competition by james causey _they would learn what caused the murderous disease--if it was the last thing they did!_ greta _january 18, earth time_ i wish max would treat me like a _woman_. an hour ago, at dinner, john armitage proposed a toast, especially for my benefit. he loves to play the gallant. big man, silver mane, very blue eyes, a porcelain smile. the head of wsc, the perfect example of the politician-scientist. "to the colony," he announced, raising his glass. "may epsilon love them and keep them. may it only be transmittal trouble." "amen," max said. we drank. taylor bishop put down his glass precisely. bishop is a gray little man with a diffident voice that belies his reputation as the best biochemist in the system. "has farragut hinted otherwise?" he asked mildly. armitage frowned. "it would be scarcely prudent for senator farragut to alarm the populace with disaster rumors." bishop looked at him out of his pale eyes. "besides, it's an election year." the silence was suddenly ugly. then armitage chuckled. "all right," he said. "so the senator wants to be a national hero. the fact still remains that epsilon had better be habitable or pan-asia will scream we're hogging it. they want war anyway. within a month--boom." * * * * * for a moment, i was afraid he was going to make a speech about earth's suffocating billions, the screaming tension of the cold war, and the sacred necessity of our mission. if he had, i'd have gotten the weeping shrieks. some responsibilities are too great to think about. but instead he winked at me. for the first time, i began to realize why armitage was the director of the scientists' world council. "hypothesis, greta," he said. "epsilon is probably a paradise. why should the test colony let the rest of the world in on it? they're being selfish." i giggled. we relaxed. after supper, armitage played chess with bishop while i followed max into the control room. "soon?" i said. "planetfall in eighteen hours, doctor." he said it stiffly, busying himself at the controls. max is a small dark man with angry eyes and the saddest mouth i've ever seen. he is also a fine pilot and magnificent bacteriologist. i wanted to slap him. i hate these professional british types that think a female biochemist is some sort of freak. "honestly," i said. "what do you think?" "disease," he said bitterly. "for the first six months they reported on schedule, remember? a fine clean planet, no dominant life-forms, perfect for immigration; unique, one world in a billion. abruptly they stopped sending. you figure it." i thought about it. "i read your thematic on venusian viruses," he said abruptly. "good show. you should be an asset to us, doctor." "thanks!" i snapped. i was so furious that i inadvertently looked into the cabin viewplate. bishop had warned me. it takes years of deep-space time to enable a person to stare at the naked universe without screaming. it got me. the crystal thunder of the stars, that horrible hungry blackness. i remember i was sort of crying and fighting, then max had me by the shoulders, holding me gently. he was murmuring and stroking my hair. after a time, i stopped whimpering. [illustration: illustrated by stone] "thanks," i whispered. "you'd better get some sleep, greta," he said. i turned in. i think i'm falling in love. * * * * * _january 19_ today we made planetfall. it took max a few hours to home in on the test colony ship. he finally found it, on the shore of an inland sea that gleamed like wrinkled blue satin. for a time we cruised in widening spirals, trying to detect some signs of life. there was nothing. we finally landed. max and armitage donned spacesuits and went toward the colony ship. they came back in a few hours, very pale. "they're dead." armitage's voice cracked as he came out of the airlock. "all of them." "skeletons," max said. "how?" bishop said. armitage's hands were shaking as he poured a drink. "looks like civil war." "but there were a hundred of them," i whispered. "they were _dedicated_--" "i wonder," bishop said thoughtfully. "white and brown and yellow. russian and british and french and german and chinese and spanish. they were chosen for technical background rather than emotional stability." "rot!" armitage said like drums beating. "it's some alien bug, some toxin. we've got to isolate it, find an antibody." he went to work. * * * * * _january 22_ i'm scared. it's taken three days to finalize the atmospheric tests. oxygen, nitrogen, helium, with trace gases. those trace gases are stinkers. bishop discovered a new inert gas, heavier than xenon. he's excited. i'm currently checking stuff that looks like residual organic, and am not too happy about it. still, this atmosphere seems pure. armitage is chafing. "it's in the flora," he insisted today. "something, perhaps, that they ate." he stood with a strained tautness, staring feverishly at the chronometer. "senator farragut's due to make contact soon. what'll i tell him?" "that we're working on it," bishop said dryly. "that the four best scientists in the galaxy are working toward the solution." "that's good," armitage said seriously. "but they'll worry. you _are_ making progress?" i wanted to wrap a pestle around his neck. we were all in the control room an hour later. armitage practically stood at attention while farragut's voice boomed from the transmitter. it was very emetic. the senator said the entire hemisphere was waiting for us to announce the planet was safe for immigration. he said the stars were a challenge to man. he spoke fearfully of the coming world crisis. epsilon was man's last chance for survival. armitage assured him our progress was satisfactory, that within a few days we would have something tangible to report. the senator said we were heroes. finally it was over. max yawned. "wonder how many voters start field work at once." armitage frowned. "it's not funny, cizon. not funny at all. inasmuch as we've checked out the atmosphere, i suggest we start field work at once." taylor blinked. "we're still testing a few residual--" "i happen to be nominal leader of this party." armitage stood very tall, very determined. "obviously the atmosphere is pure. let's make some progress!" * * * * * _february 2_ this is progress? for the past ten days, we've worked the clock around. quantitative analysis, soil, water, flora, fauna, cellular, microscopic. nothing. max has discovered a few lethal alkaloids in some greenish tree fungus, but i doubt if the colony were indiscriminate fungus eaters. bishop has found a few new unicellular types, but nothing dangerous. there's one tentacled thing that reminds me of a frightened rotifer. max named it _armitagium_. armitage is pleased. perhaps the fate of the hundred colonists will remain one of those forever unsolved mysteries, like the fate of the _mary celeste_ or the starship _prometheus_. this planet's _clean_. * * * * * _february 4_ today max and i went specimen-hunting. it must be autumn on epsilon. everywhere the trees are a riot of scarlet and ocher, the scrubby bushes are shedding their leaves. once we came upon a field of thistlelike plants with spiny seed-pods that opened as we watched, the purple spores drifting afield in an eddy of tinted mist. max said it reminded him of scotland. he kissed me. on the way back to the ship we saw two skeletons. each had its fingers tightly locked about the other's throat. * * * * * _february 20_ we have, to date, analyzed nine hundred types of plant life for toxin content. bishop has tested innumerable spores and bacteria. our slide file is immense and still growing. max has captured several insects. there is one tiny yellow bush-spider with a killing bite, but the species seem to be rare. bishop has isolated a mold bacterium that could cause a high fever, but its propagation rate is far too low to enable it to last long in the bloodstream. the most dangerous animal seems to be a two-foot-tall arthropod. they're rare and peaceable. bishop vivisected one yesterday and found nothing alarming. last night i dreamed about the first expedition. i dreamed they all committed suicide because epsilon was too good for them. this is ridiculous! we're working in a sort of quiet madness getting no closer to the solution. armitage talked to senator farragut yesterday and hinted darkly that the first ship's hydroponics system went haywire and that an improper carbohydrate imbalance killed the colony. pretty thin. farragut's getting impatient. bishop looks haggard. max looks grim. * * * * * _february 23_ our quantitative tests are slowing down. we play a rubber of bridge each night before retiring. last night i trumped max's ace and he snarled at me. we had a fight. this morning i found a bouquet of purple spore-thistles at my cabin door. max is sweet. this afternoon, by mutual consent, we all knocked off work and played bridge. bishop noticed the thistle bouquet in a vase over the chronometer. he objected. "they're harmless," max said. "besides, they smell nice." i can hardly wait for tomorrow's rubber. our work is important, but one does need relaxation. * * * * * _february 25_ armitage is cheating. yesterday he failed to score one of my overtricks. we argued bitterly about it. taylor, of course, sided with him. three hands later, armitage got the bid in hearts. "one hundred and fifty honors," he announced. "that's a lie," i said. "it was only a hundred," he grinned. "but thank you, greta. now i shan't try the queen finesse." no wonder they've won the last three evenings! max is furious with them both. * * * * * _february 28_ we played all day. max and i kept losing. i always knew armitage was a pompous toad, but i never realized he was _slimy_. this afternoon it was game all, and armitage overcalled my diamond opener with three spades. bishop took him to four and i doubled, counting on my ace-king of hearts and diamonds. i led out my diamond ace and armitage trumped from his hand. bishop laid down his dummy. he had clubs and spades solid, with doubleton heart and diamonds. "none?" max asked armitage dangerously. armitage tittered. i wanted to scratch his eyes out. he drew trump immediately and set up clubs on board, dumping the heart losers from his hand, and finally sluffing--_two diamonds_. "made seven," he said complacently, "less two for the diamond renege makes five, one overtrick doubled. we were vulnerable, so it's game and rubber." i gasped. "you reneged deliberately!" "certainly. doubleton in hearts and diamonds in my hand. if you get in, i'm down one. as it was, i made an overtrick. the only penalty for a renege is two tricks. the rule book does not differentiate between deliberate and accidental reneges. sorry." i stared at his florid throat, at his jugular. i could feel my mouth twitching. on the next hand i was dummy. i excused myself and went into the lab. i found a scalpel. i came up quietly behind armitage and bishop saw what i was going to do and shouted and i was not nearly fast enough. armitage ducked and bishop tackled me. "thanks, dear," max said thoughtfully, looking at the cards scattered on the floor. "we would have been set one trick. club finesse fails." "she's crazy!" armitage's mouth worked. "the strain's too much for her!" i cried. i apologized hysterically. after a while, i convinced them i was all right. max gave me a sedative. we did not play any more bridge. over supper i kept staring at armitage's throat. after eating, i went for a long walk. when i got back to the ship, everyone was sleeping. * * * * * _march 1_ bishop found armitage this morning, in his cabin. he came out, very pale, staring at me. "you bitch," he said. "ear to ear. now what'll i do for a partner?" "you can't prove it," i said. "we'll have to confine her to quarters," max said wearily. "i'll tell farragut." "and let him know the expedition is failing?" max sighed. "you're right. we'll tell them armitage had an accident." i said seriously, "it was obviously suicide. his mind snapped." "oh, god," max said. they buried armitage this afternoon. from my cabin, i watched them dig the grave. cheaters never prosper. * * * * * _march 2_ max talked with senator farragut this morning. he said armitage had died a hero's death. farragut sounds worried. the pan-asians have withdrawn their embassy from imperial africa. tension is mounting on the home front. immigration _must_ start this week. max was very reassuring. "just a few final tests, senator. we want to make sure." we puttered in our laboratories all afternoon. bishop seemed bored. after dinner he suggested three-handed bridge and max said he knew a better game, a friendly game his grandmother had taught him--hearts. * * * * * _march 5_ it's a plot! all day long bishop and max have managed to give me the queen of spades. it's deliberate, of course. three times i've tried for the moon and bishop has held out one damned little heart at the end. once max was slightly ahead on points and bishop demanded to see the score. i thought for a moment they would come to blows, but bishop apologized. "it's just that i hate to lose," he said. "quite," max said. when we finally turned in, bishop was ahead on points. too far ahead. * * * * * _march 6_ i suppose it's bishop's laugh. it has a peculiar horselike stridency that makes me want to tear out his throat. twice today i've broken down and cried when he made a jackpot. i'm not going to cry any more. supper was the usual, beef-yeast and vita-ale. i remember setting bishop's plate in front of him, and the way his pale eyes gleamed between mouthfuls. "three thousand points ahead," he gloated. "you'll never catch me now. never, never!" that was when he gripped his throat and began writhing on the floor. max felt his pulse. he stared at me. "very nice," he said. "quick. did you use a derivative of that green fungus?" i said nothing. max's nostrils were white and pinched. "must i make an autopsy?" "why bother?" i said. "it's obviously heart failure." "yes, why bother?" he said. he looked tired. "stay in your cabin, greta. i'll bring your meals." "i don't trust you." his laughter had a touch of madness. * * * * * _march 10_ max unlocked my cabin door this morning. he looked drawn. "listen," he said. "i've checked my respiration, pulse, saliva, temperature. all normal." "so?" "come here," he said. i followed him into the lab. he indicated a microscope. his eyes were bright. "well?" "a drop of my blood," he said. "look." i squinted into the microscope. i saw purple discs. oddly, they did not attack the red blood cells. there was no fission, no mitosis. the leucocytes, strangely enough, let them alone. my hands were shaking as i took a sterile slide and pricked my finger. i put the slide under the microscope. i adjusted the lens and stared. purple discs, swimming in my bloodstream. thriving. minding their own business. "me, too," i said. "they're inert," max said hoarsely. "they don't affect metabolism, cause fever, or interfere with the body chemistry in any way. do they remind you of anything?" i thought about it. then i went to the slide file that was marked _flora--negative_. "right," max said. "the purple thistle. spores! the atmosphere is clogged with them. greta, my sweet, we're infected." "i feel fine," i said. all day long we ran tests. negative tests. we seem to be disgustingly healthy. "symbiosis," max said finally. "live and let live. apparently we're hosts." only one thing disturbs me. most symbiotes _do_ something for their host. something to enhance the host's survival potential. we played chess this evening. i won. max is furious. he's such a poor sport. * * * * * _march 11_ max talked with senator farragut this morning. he gave epsilon a clean bill of health and the senator thanked god. "the first starship will leave tonight," the senator said. "right on schedule, with ten thousand colonists aboard. you're world heroes!" max and i played chess the rest of the day. max won consistently. he utilizes a fianchetto that is utterly impregnable. if he wins tomorrow, i shall have to kill him. * * * * * max _march 13_ it was, of course, necessary for me to destroy armitage and bishop. they won far too often. but i am sorry about greta. yet i had to strangle her. if she hadn't started that infernal queen's pawn opening it would have been different. she beat me six times running, and on the last game i pulled a superb orang-outang, but it was too late. she saw mate in four and gave me that serpent smirk i know so well. how could i have ever been in love with her? * * * * * _march 14_ frightfully boring to be alone. i have a thought. chess. right hand against left. white and black. jolly good. * * * * * _march 16_ i haven't much time. left was black this morning and i beat him, four out of five. we're in the lab now. he's watching me scribble this. his thumb and forefinger are twitching in fury. he looks like some great white spider about to spring. he sees the scalpel, by the microscope. now his fingers are inching toward it. treacherous beast. i'm stronger. if he tries to amputate ... --james causey transcriber's note: this etext was produced from _galaxy science fiction_ may 1955. extensive research did not uncover any evidence that the u.s. copyright on this publication was renewed. minor spelling and typographical errors have been corrected without note. syndrome johnny by charles dye illustrated by emsh [transcriber's note: this etext was produced from galaxy science fiction july 1951. extensive research did not uncover any evidence that the u.s. copyright on this publication was renewed.] the plagues that struck mankind could be attributed to one man. but was he fiend ... or savior? the blood was added to a pool of other blood, mixed, centrifuged, separated to plasma and corpuscles, irradiated slightly, pasteurized slightly, frozen, evaporated, and finally banked. some of the plasma was used immediately for a woman who had bled too much in childbirth. she died. others received plasma and did not die. but their symptoms changed, including a syndrome of multiple endocrine unbalance, eccentricities of appetite and digestion, and a general pattern of emotional disturbance. an alert hospital administrator investigated the mortality rise and narrowed it to a question of who had donated blood the week before. after city residents were eliminated, there remained only the signed receipts and thumbprints of nine men. nine healthy unregistered travelers poor enough to sell their blood for money, and among them a man who carried death in his veins. the nine thumbprints were broadcast to all police files and a search began. the effort was futile, for there were many victims who had sickened and grown partially well again without recognizing the strangeness of their illness. three years later they reached the carrier stage and the epidemic spread to four cities. three more years, and there was an epidemic which spread around the world, meeting another wave coming from the opposite direction. it killed two out of four, fifty out of a hundred, twenty-seven million out of fifty million. there was hysteria where it appeared. and where it had not appeared there were quarantines to fence it out. but it could not be fenced out. for two years it covered the world. and then it vanished again, leaving the survivors with a tendency toward glandular troubles. time passed. the world grew richer, more orderly, more peaceful. a man paused in the midst of his work at the u.n. food and agriculture commission. he looked up at the red and green production map of india. "just too many people per acre," he said. "all our work at improving production ... just one jump ahead of their rising population, one jump ahead of famine. sometimes i wish to god there would be another plague to give us a breathing spell and a fair chance to get things organized." he went back to work and added another figure. two months later, he was one of the first victims of the second plague. * * * * * in the dining hall of a university, a biochemical student glanced up from his paper to his breakfast companion. "you remember johnny, the mythical carrier that they told about during the first and second epidemics of syndrome plague?" "sure. syndrome johnny. they use that myth in psychology class as a typical example of mass hysteria. when a city was nervous and expecting the plague to reach them, some superstitious fool would imagine he saw syndrome johnny and the population would panic. symbol for death or some such thing. people imagined they saw him in every corner of the world. simultaneously, of course." it was a bright morning and they were at a window which looked out across green rolling fields to a towering glass-brick building in the distance. the student who had gone back to his paper suddenly looked up again. "some peruvians here claim they saw syndrome johnny--" "idiotic superstition! you'd think it would have died down when the plague died." the other grinned. "the plague didn't die." he folded his newspaper slowly, obviously advancing an opening for a debate. his companion went on eating. "another of your wild theories, huh?" then through a mouthful of food: "all right, if the plague didn't die, where did it go?" "nowhere. _we have it now._ we all have it!" he shrugged. "a virus catalyst of high affinity for the cells and a high similarity to a normal cell protein--how can it be detected?" "then why don't people die? why aren't we sick?" "because we have sickened and recovered. we caught it on conception and recovered before birth. proof? why do you think that the countries which were known as the hungry lands are now well-fed, leisured, educated, advanced? because the birth rate has fallen! why has the birth rate fallen?" he paused, then very carefully said, "because two out of three of all people who would have lived have died before birth, slain by syndrome plague. we are all carriers now, hosts to a new guest. and"--his voice dropped to a mock sinister whisper--"with such a stranger within our cells, at the heart of the intricate machinery of our lives, who knows what subtle changes have crept upon us unnoticed!" his companion laughed. "eat your breakfast. you belong on a horror program!" * * * * * a police psychologist for the federated states of the americas was running through reports from the bureau of social statistics. suddenly he grunted, then a moment later said, "uh-huh!" "uh-huh what?" asked his superior, who was reading a newspaper with his feet up on the desk. "remember the myth, of syndrome johnny?" "ghost of syndrome plague. si, what of it?" "titaquahapahel, peru, population nine hundred, sent in a claim that he turned up there and they almost caught him. crime statistics rerouted the report to mass phenomena, of course. mass phenomena blew a tube and sent their folder on syndrome johnny over here. every report they ever had on him for ninety years back! a memo came with it." he handed the memo over. the man behind the desk looked at it. it was a small graph and some mathematical symbols. "what is it?" "it means," said the psychologist, smiling dryly, "that every crazy report about our ghost has points of similarity to every other crazy report. the whole business of syndrome johnny has been in their 'funny coincidence' file for twenty years. this time the suspect hits the averaged description of johnny too closely: a solid-looking man, unusual number of visible minor scars, and a disturbing habit of bending his fingers at the first-joint knuckles when he is thinking. the coincidence has gotten too damn funny. there's a chance we've been passing up a crime." "an extensive crime," said the man at the desk softly. he reached for the folder. "yes, a considerable quantity of murder." he leafed through the folder and then thought a while, looking at the most recent reports. thinking was what he was paid for, and he earned his excellent salary. "this thumbprint on the hotel register--the name is false, but the thumbprint looks real. could we persuade the bureau of records to give their data on that print?" "without a warrant? against constitutional immunity. no, not a chance. the public has been touchy about the right to secrecy ever since that police state was attempted in varga." "how about persuading an obliging judge to give a warrant on grounds of reasonable suspicion?" "no. we'd have the humanist press down on our necks in a minute, and any judge knows it. we'd have to prove a crime was committed. no crime, no warrant." "it seems a pity we can't even find out who the gentleman is," the crimes department head murmured, looking at the thumbprint wistfully. "no crime, no records. no records, no evidence. no evidence, no proof of crime. therefore, we must manufacture a small crime. he was attacked and he must have defended himself. someone may have been hurt in the process." he pushed a button. "do you think if i send a man down there, he could persuade one of the mob to swear out a complaint?" "that's a rhetorical question," said the psychologist, trying to work out an uncertain correlation in his reports. "with that sort of mob hysteria, the town would probably give you an affidavit of witchcraft." * * * * * "phone for you, doctor alcala." the nurse was crisp but quiet, smiling down at the little girl before vanishing again. ricardo alcala pushed the plunger in gently, then carefully withdrew the hypodermic needle from the little girl's arm. "there you are, cosita," he said, smiling and rising from the chair beside the white bed. "will that make me better, doctor?" she piped feebly. he patted her hand. "be a good girl and you will be well tomorrow." he walked out into the hospital corridor to where the desk nurse held out a phone. "alcala speaking." the voice was unfamiliar. "my deepest apologies for interrupting your work, doctor. at this late hour i'm afraid i assumed you would be at home. the name is camba, federation investigator on a health case. i would like to consult you." alcala was tired, but there was nothing to do at home. nita was at the health resort and johnny had borrowed all his laboratory space for a special synthesis of some sort, and probably would be too busy even to talk. interest stirred in him. this was a federation investigator calling; the man's work was probably important. "tonight, if that's convenient. i'll be off duty in five minutes." thirty minutes later they were ordering in a small cantina down the street from the hospital. julio camba, federation investigator, was a slender, dark man with sharp, glinting eyes. he spoke with a happy theatrical flourish. "order what you choose, senor. we're on my expense account. the resources of the federated states of all the americas stand behind your menu." alcala smiled. "i wouldn't want to add to the national debt." "not at all, senor. the federated states are only too happy thus to express a fraction of their gratitude by adding a touch of luxury to the otherwise barren and self-sacrificing life of a scientist." "you shame me," alcala said dryly. it was true that he needed every spare penny for the health of nita and the child, and for the laboratory. a penny saved from being spent on nourishment was a penny earned. he picked up the menu again and ordered steak. the investigator lit a cigar, asking casually: "do you know john osborne drake?" * * * * * alcala searched his memory. "no. i'm sorry...." then he felt for the first time how closely he was being watched, and knew how carefully his reaction and the tone of his voice had been analyzed. the interview was dangerous. for some reason, he was suspected of something. camba finished lighting the cigar and dropped the match into an ash-tray. "perhaps you know john delgados?" he leaned back into the shadowy corner of the booth. johnny! out of all the people in the world, how could the government be interested in him? alcala tried to sound casual. "an associate of mine. a friend." "i would like to contact the gentleman." the request was completely unforceful, undemanding. "i called, but he was not at home. could you tell me where he might be?" "i'm sorry, senor camba, but i cannot say. he could be on a business trip." alcala was feeling increasingly nervous. actually, johnny was working at his laboratory. "what do you know of his activities?" camba asked. "a biochemist." alcala tried to see past the meditative mask of the thin dark face. "he makes small job-lots of chemical compounds. special bug spray for sale to experimental plantations, hormone spray for fruits, that sort of thing. sometimes, when he collects some money ahead, he does research." camba waited, and his silence became a question. alcala spoke reluctantly, anger rising in him. "oh, it's genuine research. he has some patents and publications to his credit. you can confirm that if you choose." he was unable to keep the hostility out of his voice. a waiter came and placed steaming platters of food on the table. camba waited until he was gone. "you know him well, i presume. is he sane?" the question was another shock. alcala thought carefully, for any man might be insane in secret. "yes, so far as i know." he turned his attention to the steak, but first took three very large capsules from a bottle in his pocket. "i would not expect that a doctor would need to take pills," camba remarked with friendly mockery. "i don't need them," alcala explained. "mixed silicones. i'm guinea pigging." "can't such things be left to the guinea pigs?" camba asked, watching with revulsion as alcala uncapped the second bottle and sprinkled a layer of gray powder over his steak. "guinea pigs have no assimilation of silicones; only man has that." "yes, of course. i should have remembered from your famous papers, _the need of trace silicon in human diet_ and _silicon deficiency diseases_." * * * * * obviously camba had done considerable investigating of alcala before approaching him. he had even given the titles of the research papers correctly. alcala's wariness increased. "what is the purpose of the experiment this time?" asked the small dark federation agent genially. "to determine the safe limits of silicon consumption and if there are any dangers in an overdose." "how do you determine that? by dropping dead?" he could be right. perhaps the test should be stopped. every day, with growing uneasiness, alcala took his dose of silicon compound, and every day, the chemical seemed to be absorbed completely--not released or excreted--in a way that was unpleasantly reminiscent of the way arsenic accumulated without evident damage, then killed abruptly without warning. already, this evening, he had noticed that there was something faulty about his coordination and weight and surface sense. the restaurant door had swung back with a curious lightness, and the hollow metal handle had had a curious softness under his fingers. something merely going wrong with the sensitivity of his fingers--? he tapped his fingertips on the heavy indestructible silicone plastic table top. there was a feeling of heaviness in his hands, and a feeling of faint rubbery _give_ in the table. tapping his fingers gently, his heavy fingers ... the answer was dreamily fantastic. _i'm turning into silicon plastic myself_, he thought. but how, why? he had not bothered to be curious before, but the question had always been--what were supposedly insoluble silicons doing assimilating into the human body at all? several moments passed. he smoothed back his hair with his oddly heavy hand before picking up his fork again. "i'm turning into plastic," he told camba. "i beg your pardon?" "nothing. a joke." camba was turning into plastic, too. everyone was. but the effect was accumulating slowly, by generations. * * * * * camba lay down his knife and started in again. "what connections have you had with john delgados?" _concentrate on the immediate situation._ alcala and johnny were obviously in danger of some sort of mistaken arrest and interrogation. as alcala focused on the question, one errant whimsical thought suddenly flitted through the back of his mind. in red advertising letters: try our new model rust-proof, waterproof, heat & scald resistant, strong--extra-long-wearing human being! he laughed inwardly and finally answered: "friendship. mutual interest in high ion colloidal suspensions and complex synthesis." impatience suddenly mastered him. "exactly what is it you wish to know, senor? perhaps i could inform you if i knew the reasons for your interest." camba chose a piece of salad with great care. "we have reason to believe that he is syndrome johnny." alcala waited for the words to clarify. after a moment, it ceased to be childish babble and became increasingly shocking. he remembered the first time he had met john delgados, the smile, the strong handclasp. "call me johnny," he had said. it had seemed no more than a nickname. the investigator was watching his expression with bright brown eyes. johnny, yes ... but not syndrome johnny. he tried to think of some quick refutation. "the whole thing is preposterous, senor camba. the myth of syndrome plague johnny started about a century ago." "doctor alcala"--the small man in the gray suit was tensely sober--"john delgados is very old, and john delgados is not his proper name. i have traced his life back and back, through older and older records in argentina, panama, south africa, the united states, china, canada. everywhere he has paid his taxes properly, put his fingerprints on file as a good citizen should. and he changed his name every twenty years, applying to the courts for permission with good honest reasons for changing his name. everywhere he has been a laboratory worker, held patents, sometimes made a good deal of money. he is one hundred and forty years old. his first income tax was paid in 1970, exactly one hundred and twenty years ago." "other men are that old," said alcala. "other men are old, yes. those who survived the two successive plagues, were unusually durable." camba finished and pushed back his plate. "there is no crime in being long-lived, surely. but he has changed his name five times!" "that proves nothing. whatever his reasons for changing his name, it doesn't prove that he is syndrome johnny any more than it proves he is the cow that jumped over the moon. syndrome johnny is a myth, a figment of mob delirium." * * * * * as he said it, he knew it was not true. a federation investigator would not be on a wild goose chase. the plates were taken away and cups of steaming black coffee put between them. he would have to warn johnny. it was strange how well you could know a man as well as he knew johnny, firmly enough to believe that, despite evidence, everything the man did was right. "why must it be a myth?" camba asked softly. "it's ridiculous!" alcala protested. "why would any man--" his voice cut off as unrelated facts fell into a pattern. he sat for a moment, thinking intensely, seeing the century of plague as something he had never dreamed.... a price. not too high a price in the long run, considering what was purchased. of course, the great change over into silicon catalysis would be a shock and require adjustment and, of course, the change must be made in several easy stages--and those who could not adjust would die. "go on, doctor," camba urged softly. "'_why_ would any man--'" he tried to find a way of explaining which would not seem to have any relationship to john delgados. "it has been recently discovered"--but he did not say _how_ recently--"that the disease of syndrome plague was not a disease. it is an improvement." he had spoken clumsily. "an improvement on life?" camba laughed and nodded, but there were bitterness and anger burning behind the small man's smile. "people can be improved to death by the millions. yes, yes, go on, senor. you fascinate me." "we are stronger," alcala told him. "we are changed chemically. the race has been improved!" "come, doctor alcala," camba said with a sneering merriment, "the syndrome plagues have come and they have gone. where is this change?" alcala tried to express it clearly. "we are stronger. potentially, we are tremendously stronger. but we of this generation are still weak and ill, as our parents were, from the shock of the change. and we need silicone feeding; we have not adjusted yet. our illness masks our strength." he thought of what that strength would be! camba smiled and took out a small notebook. "the disease is connected with silicones, you say? the original name of john delgados was john osborne drake. his father was osborne drake, a chemist at dow corning, who was sentenced to the electric chair in 1967 for unauthorized bacterial experiments which resulted in an accidental epidemic and eight deaths. dow corning was the first major manufactury of silicones in america, though not connected in any way with osborne drake's criminal experiments. it links together, does it not?" "it is not a disease, it is strength!" alcala insisted doggedly. * * * * * the small investigator looked up from his notebook and his smile was an unnatural thing, a baring of teeth. "half the world died of this strength, senor. if you will not think of the men and women, think of the children. millions of children died!" the waiter brought the bill, dropping it on the table between them. "lives will be saved in the long run," alcala said obstinately. "individual deaths are not important in the long run." "that is hardly the philosophy for a doctor, is it?" asked camba with open irony, taking the bill and rising. they went out of the restaurant in silence. camba's 'copter stood at the curb. "would you care for a lift home, doctor alcala?" the offer was made with the utmost suavity. alcala hesitated fractionally. "why, yes, thank you." it would not do to give the investigator any reason for suspicion by refusing. as the 'copter lifted into the air, camba spoke with a more friendly note in his voice, as if he humored a child. "come, alcala, you're a doctor dedicated to saving lives. how can you find sympathy for a murderer?" alcala sat in the dark, looking through the windshield down at the bright street falling away below. "i'm not a practicing medico; only one night a week do i come to the hospital. i'm a research man. i don't try to save individual lives. i'm dedicated to improving the average life, the average health. can you understand that? individuals may be sick and individuals may die, but the average lives on. and if the average is better, then i'm satisfied." the 'copter flew on. there was no answer. "i'm not good with words," said alcala. then, taking out his pen-knife and unfolding it, he said, "watch!" he put his index finger on the altimeter dial, where there was light, and pressed the blade against the flesh between his finger and his thumb. he increased the pressure until the flesh stood out white on either side of the blade, bending, but not cut. "three generations back, this pressure would have gone right through the hand." he took away the blade and there was only a very tiny cut. putting the knife away, he brought out his lighter. the blue flame was steady and hot. alcala held it close to the dashboard and put his finger directly over it, counting patiently, "one, two, three, four, five--" he pulled the lighter back, snapping it shut. "three generations ago, a man couldn't have held a finger over that flame for more than a tenth part of that count. doesn't all this prove something to you?" the 'copter was hovering above alcala's house. camba lowered it to the ground and opened the door before answering. "it proves only that a good and worthy man will cut and burn his hand for an unworthy friendship. good night." disconcerted, alcala watched the 'copter lift away into the night, then, turning, saw that the lights were still on in the laboratory. camba might have deduced something from that, if he knew that nita and the girl were not supposed to be home. alcala hurried in. johnny hadn't left yet. he was sitting at alcala's desk with his feet on the wastebasket, the way alcala often liked to sit, reading a technical journal. he looked up, smiling. for a moment alcala saw him with the new clarity of a stranger. the lean, weathered face; brown eyes with smile deltas at the corners; wide shoulders; steady, big hands holding the magazine--solid, able, and ruthless enough to see what had to be done, and do it. "i was waiting for you, ric." "the feds are after you." ricardo alcala had been running. he found he was panting and his heart was pounding. delgados' smile did not change. "it's all right, ric. everything's done. i can leave any time now." he indicated a square metal box standing in a corner. "there's the stuff." what stuff? the product johnny had been working on? "you haven't time for that now, johnny. you can't sell it. they'd watch for anyone of your description selling chemicals. let me loan you some money." "thanks." johnny was smiling oddly. "everything's set. i won't need it. how close are they to finding me?" "they don't know where you're staying." alcala leaned on the desk edge and put out his hand. "they tell me you're syndrome johnny." "i thought you'd figured that one out." johnny shook his hand formally. "the name is john osborne drake. you aren't horrified?" "no." alcala knew that he was shaking hands with a man who would be thanked down all the successive generations of mankind. he noticed again the odd white web-work of scars on the back of johnny's hand. he indicated them as casually as he could. "where did you pick those up?" * * * * * john drake glanced at his hand. "i don't know, ric. truthfully. i've had my brains beaten in too often to remember much any more. unimportant. there are instructions outlining plans and methods filed in safety deposit boxes in almost every big city in the world. always the same typing, always the same instructions. i can't remember who typed them, myself or my father, but i must have been expected to forget or they wouldn't be there. up to eleven, my memory is all right, but after dad started to remake me, everything gets fuzzy." "after he did _what_?" johnny smiled tiredly and rested his head on one hand. "he had to remake me chemically, you know. how could i spread change without being changed myself? i couldn't have two generations to adapt to it naturally like you, ric. it had to be done artificially. it took years. you understand? i'm a community, a construction. the cells that carry on the silicon metabolism in me are not human. dad adapted them for the purpose. i helped, but i can't remember any longer how it was done. i think when i've been badly damaged, organization scatters to the separate cells in my body. they can survive better that way, and they have powers of regrouping and healing. but memory can't be pasted together again or regrown." john drake rose and looked around the laboratory with something like triumph. "they're too late. i made it, ric. there's the catalyst cooling over there. this is the last step. i don't think i'll survive this plague, but i'll last long enough to set it going for the finish. the police won't stop me until it's too late." * * * * * another plague! the last one had been before alcala was born. he had not thought that johnny would start another. it was a shock. alcala walked over to the cage where he kept his white mice and looked in, trying to sort out his feelings. the white mice looked back with beady bright eyes, caged, not knowing they were waiting to be experimented upon. a timer clicked and john delgados-drake became all rapid efficient activity, moving from valve to valve. it lasted a half minute or less, then drake had finished stripping off the lab whites to his street clothes. he picked up the square metal box containing the stuff he had made, tucked it under his arm and held out a solid hand again to alcala. "good-by, ric. wish me luck. close up the lab for me, will you?" alcala took the hand numbly and mumbled something, turned back to the cages and stared blindly at the mice. drake's brisk footsteps clattered down the stairs. * * * * * another step forward for the human race. god knew what wonders for the race were in that box. perhaps something for nerve construction, something for the mind--the last and most important step. he should have asked. there came at last a pressure that was a thought emerging from the depth of intuition. _doctor ricardo alcala will die in the next plague, he and his ill wife nita and his ill little girl.... and the name of alcala will die forever as a weak strain blotted from the bloodstream of the race...._ he'd find out what was in the box by dying of it! he tried to reason it out, but only could remember that nita, already sickly, would have no chance. and alcala's family genes, in attempting to adapt to the previous steps, had become almost sterile. it had been difficult having children. the next step would mean complete sterility. the name of alcala would die. the future might be wonderful, but it would not be _his_ future! "johnny!" he called suddenly, something like an icy lump hardening in his chest. how long had it been since johnny had left? running, alcala went down the long half-lit stairs, out the back door and along the dark path toward the place where johnny's 'copter had been parked. a light shone through the leaves. it was still there. "johnny!" john osborne drake was putting his suitcase into the rear of the 'copter. "what is it, ric?" he asked in a friendly voice without turning. _it would be impossible to ask him to change his mind._ alcala found a rock, raised it behind syndrome johnny's back. "i know i'm being anti-social," he said regretfully, and then threw the rock away. his fist was enough like stone to crush a skull. well, naturally kaiser would transmit baby talk messages to his mother ship! he was- growing up on big muddy by charles v. de vet illustrated by turpin [transcriber's note: this etext was produced from galaxy science fiction july 1957. extensive research did not uncover any evidence that the u.s. copyright on this publication was renewed.] kaiser stared at the tape in his hand for a long uncomprehending minute. how long had the stuff been coming through in this inane baby talk? and why hadn't he noticed it before? why had he had to read this last communication a third time before he recognized anything unusual about it? he went over the words again, as though maybe this time they'd read as they should. oo is sick, smoky. do to beddy-by. keep um warm. when um feels better, let usns know. ss ii kaiser let himself ease back in the pilot chair and rolled the tape thoughtfully between his fingers. overhead and to each side, large drops of rain thudded softly against the transparent walls of the scout ship and dripped wearily from the bottom ledge to the ground. "damn this climate!" kaiser muttered irrelevantly. "doesn't it ever do anything here except rain?" his attention returned to the matter at hand. why the baby talk? and why was his memory so hazy? how long had he been here? what had he been doing during that time? listlessly he reached for the towel at his elbow and wiped the moisture from his face and bare shoulders. the air conditioning had gone out when the scout ship cracked up. he'd have to repair the scout or he was stuck here for good. he remembered now that he had gone over the job very carefully and thoroughly, and had found it too big to handle alone--or without better equipment, at least. yet there was little or no chance of his being able to find either here. calmly, deliberately, kaiser collected his thoughts, his memories, and brought them out where he could look at them: the mother ship, _soscites ii_, had been on the last leg of its planet-mapping tour. it had dropped kaiser in the one remaining scout ship--the other seven had all been lost one way or another during the exploring of new worlds--and set itself into a giant orbit about this planet that kaiser had named big muddy. the _soscites ii_ had to maintain its constant speed; it had no means of slowing, except to stop, and no way to start again once it did stop. its limited range of maneuverability made it necessary to set up an orbit that would take it approximately one month, earth time, to circle a pinpointed planet. and now its fuel was low. kaiser had that one month to repair his scout or be stranded here forever. that was all he could remember. nothing of what he had been doing recently. a small shiver passed through his body as he glanced once again at the tape in his hand. baby talk.... * * * * * one thing he could find out: how long this had been going on. he turned to the communicator and unhooked the paper receptacle on its bottom. it held about a yard and a half of tape, probably his last several messages--both those sent and those received. he pulled it out impatiently and began reading. the first was from himself: your suggestions no help. how am i going to repair damage to scout without proper equipment? and where do i get it? do you think i found a tool shop down here? for god's sake, come up with something better. visited seal-people again today. still have their stink in my nose. found huts along river bank, so i guess they don't live in water. but they do spend most of their time there. no, i have no way of estimating their intelligence. i would judge it averages no higher than seven-year-old human. they definitely do talk to one another. will try to find out more about them, but you get to work fast on how i repair scout. swelling in arm worse and am developing a fever. temperature 102.7 an hour ago. smoky the ship must have answered immediately, for the return message time was six hours later than his own, the minimum interval necessary for two-way exchange. doing our best, smoky. your immediate problem, as we see it, is to keep well. we fed all the information you gave us into sam, but you didn't have much except the sting in your arm. as expected, all that came out was "data insufficient." try to give us more. also detail all symptoms since your last report. in the meantime, we're doing everything we can at this end. good luck. ss ii sam, kaiser knew, was the ship's mechanical diagnostician. his report followed: arm swollen. unable to keep down food last twelve hours. about two hours ago, entire body turned livid red. brief periods of blankness. things keep coming and going. sick as hell. hurry. smoky the ship's next message read: infection quite definite. but something strange there. give us anything more you have. ss ii his own reply perplexed kaiser: last letter funny. i not understand. why is oo sending garble talk? did usns make up secret messages? smoky the expedition, apparently, was as puzzled as he: what's the matter, smoky? that last message was in plain terran. no reason why you couldn't read it. and why the baby talk? if you're spoofing, stop. give us more symptoms. how are you feeling now? ss ii the baby talk was worse on kaiser's next: twazy. what for oo tending twazy letters? fink um can wead twazy letters? skin all yellow now. cold. cold. co the ship's following communication was three hours late. it was the last on the tape--the one kaiser had read earlier. apparently they decided to humor him. oo is sick, smoky. do to beddy-by. keep um warm. when um feels better, let usns know. ss ii that was not much help. all it told him was that he had been sick. he felt better now, outside of a muscular weariness, as though convalescing from a long illness. he put the back of his hand to his forehead. cool. no fever anyway. he glanced at the clock-calendar on the instrument board and back at the date and time on the tape where he'd started his baby talk. twenty hours. he hadn't been out of his head too long. he began punching the communicator keys while he nibbled at a biscuit. seem to be fully recovered. feeling fine. anything new from sam? and how about the damage to scout? give me anything you have on either or both. smoky kaiser felt suddenly weary. he lay on the scout's bunk and tried to sleep. soon he was in that phantasm land between sleep and wakefulness--he knew he was not sleeping, yet he did dream. it was the same dream he had had many times before. in it, he was back home again, the home he had joined the space service to escape. he had realized soon after his marriage that his wife, helene, did not love him. she had married him for the security his pay check provided. and though it soon became evident that she, too, regretted her bargain, she would not divorce him. instead, she had her revenge on him by persistent nagging, by letting herself grow fat and querulous, and by caring for their house only in a slovenly way. her crippled brother had moved in with them the day they were married. his mind was as crippled as his body and he took an unhealthy delight in helping his sister torment kaiser. * * * * * kaiser came wide awake in a cold sweat. the clock showed that only an hour had passed since he had sent his last message to the ship. still five more long hours to wait. he rose and wiped the sweat from his neck and shoulders and restlessly paced the small corridor of the scout. after a few minutes, he stopped pacing and peered out into the gloom of big muddy. the rain seemed to have eased off some. not much more than a heavy drizzle now. kaiser reached impulsively for the slicker he had thrown over a chest against one wall and put it on, then a pair of hip-high plastic boots and a plastic hat. he opened the door. the scout had come to rest with a slight tilt when it crashed, and kaiser had to sit down and roll over onto his stomach to ease himself to the ground. the weather outside was normal for big muddy: wet, humid, and warm. kaiser sank to his ankles in soft mud before his feet reached solid ground. he half walked and half slid to the rear of the scout. beside the ship, the "octopus" was busily at work. tentacles and antennae, extending from the yard-high box of its body, tested and recorded temperature, atmosphere, soil, and all other pertinent planetary conditions. the octopus was connected to the ship's communicator and all its findings were being transmitted to the mother ship for study. kaiser observed that it was working well and turned toward a wide, sluggish river, perhaps two hundred yards from the scout. once there, he headed upstream. he could hear the pipings, and now and then a higher whistling, of the seal-people before he reached a bend and saw them. as usual, most were swimming in the river. one old fellow, whose chocolate-brown fur showed a heavy intermixture of gray, was sitting on the bank of the river just at the bend. perhaps a lookout. he pulled himself to his feet as he spied kaiser and his toothless, hard-gummed mouth opened and emitted a long whistle that might have been a greeting--or a warning to the others that a stranger approached. the native stood perhaps five feet tall, with the heavy, blubbery body of a seal, and short, thick arms. membranes connected the arms to his body from shoulder-pits to mid-biceps. the arms ended in three-fingered, thumbless hands. his legs also were short and thick, with footpads that splayed out at forty-five-degree angles. they gave his legs the appearance of a split tail. about him hung a rank-fish smell that made kaiser's stomach squirm. the old fellow sounded a cheerful chirp as kaiser came near. feeling slightly ineffectual, kaiser raised both hands and held them palm forward. the other chirped again and kaiser went on toward the main group. * * * * * they had stopped their play and eating as kaiser approached and now most of them swam in to shore and stood in the water, staring and piping. they varied in size from small seal-pups to full-grown adults. some chewed on bunches of water weed, which they manipulated with their lips and drew into their mouths. they had mammalian characteristics, kaiser had noted before, so it was not difficult to distinguish the females from the males. the proportion was roughly fifty-fifty. several of the bolder males climbed up beside kaiser and began pawing his plastic clothing. kaiser stood still and tried to keep his breathing shallow, for their odor was almost more than he could bear. one native smeared kaiser's face with an exploring paw and kaiser gagged and pushed him roughly away. he was bound by regulations to display no hostility to newly discovered natives, but he couldn't take much more of this. a young female splashed water on two young males who stood near and they turned with shrill pipings and chased her into the water. the entire group seemed to lose interest in kaiser and joined in the chase, or went back to other diversions of their own. kaiser's inspectors followed. they were a mindless lot, kaiser observed. the river supplied them with an easy existence, with food and living space, and apparently they had few natural enemies. kaiser walked away, following the long slow bend of the river, and came to a collection of perhaps two hundred dwellings built in three haphazard rows along the river bank. he took time to study their construction more closely this time. they were all round domes, little more than the height of a man, built of blocks that appeared to be mud, packed with river weed and sand. how they were able to dry these to give them the necessary solidity, kaiser did not know. he had found no signs that they knew how to use fire, and all apparent evidence was against their having it. they then had to have sunlight. maybe it rained less during certain seasons. the domes' construction was based on a series of four arches built in a circle. when the base covering the periphery had been laid, four others were built on and between them, and continued in successive tiers until the top was reached. each tier thus furnished support for the next above. no other framework was needed. the final tier formed the roof. they made sound shelters, but kaiser had peered into several and found them dark and dank--and as smelly as the natives themselves. the few loungers in the village paid little attention to kaiser and he wandered through the irregular streets until he became bored and returned to the scout. the _soscites ii_ sent little that helped during the next twelve hours and kaiser occupied his time trying again to repair the damage to the scout. the job appeared maddeningly simply. as the scout had glided in for a soft landing, its metal bottom had ridden a concealed rock and bent inward. the bent metal had carried up with it the tube supplying the fuel pump and flattened it against the motor casing. * * * * * opening the tube again would not have been difficult, but first it had to be freed from under the ship. kaiser had tried forcing the sheet metal back into place with a small crowbar--the best leverage he had on hand--but it resisted his best efforts. he still could think of no way to do the job, simple as it was, though he gave his concentration to it the rest of the day. that evening, kaiser received information from the _soscites ii_ that was at least definite: set yourself for a shock, smoky. sam finally came through. you won't like what you hear. at least not at first. but it could be worse. you have been invaded by a symbiote--similar to the type found on the sand world, bartel-bleethers. give us a few more hours to work with sam and we'll get you all the particulars he can give us. hang on now! soscites ii kaiser's reply was short and succinct: what the hell? smoky _soscites ii's_ next communication followed within twenty minutes and was signed by the ship's doctor: just a few words, smoky, in case you're worried. i thought i'd get this off while we're waiting for more information from sam. remember that a symbiote is not a parasite. it will not harm you, except inadvertently. your welfare is as essential to it as to you. almost certainly, if you die, it will die with you. any trouble you've had so far was probably caused by the symbiote's difficulty in adjusting itself to its new environment. in a way, i envy you. more later, when we finish with sam. j. g. zarwell kaiser did not answer. the news was so startling, so unforeseen, that his mind refused to accept the actuality. he lay on the scout's bunk and stared at the ceiling without conscious attention, and with very little clear thought, for several hours--until the next communication came in: well, this is what sam has to say, smoky. symbiote amicable and apparently swiftly adaptable. your changing color, difficulty in eating and even baby talk were the result of its efforts to give you what it believed you needed or wanted. changing color: protective camouflage. trouble keeping food down: it kept your stomach empty because it sensed you were in trouble and might have need for sharp reflexes, with no excess weight to carry. the baby talk we aren't too certain about, but our best conclusion is that when you were a child, you were most happy. it was trying to give you back that happy state of mind. obviously it quickly recognized the mistakes it made and corrected them. sam came up with a few more ideas, but we want to work on them a bit before we send them through. sleep on this. ss ii * * * * * kaiser could imagine that most of the crew were not too concerned about the trouble he was in. he was not the gregarious type and had no close friends on board. he had hoped to find the solitude he liked best in space, but he had been disappointed. true, there were fewer people here, but he was brought into such intimate contact with them that he would have been more contented living in a crowded city. his naturally unsociable nature was more irksome to the crew because he was more intelligent and efficient than they were. he did his work well and painstakingly and was seldom in error. they would have liked him better had he been more prone to mistakes. he was certain that they respected him, but they did not like him. and he returned the dislike. the suggestion that he get some sleep might not be a bad idea. he hadn't slept in over eighteen hours, kaiser realized--and fell instantly asleep. the communicator had a message waiting for him when he awoke: sam couldn't help us much on this part, but after research and much discussion, we arrived at the following two conclusions. first, physical property of symbiote is either that of a very thin liquid or, more probably, a virus form with swift propagation characteristic. it undoubtedly lives in your blood stream and permeates your system. second, it seemed to us, as it must have to you, that the symbiote could only know what you wanted by reading your mind. however, we believe differently now. we think that it has such close contact with your glands and their secretions, which stimulate emotion, that it can gauge your feelings even more accurately than you yourself can. thus it can judge your likes and dislikes quite accurately. we would like to have you test our theory. there are dozens of ways. if you are stumped and need suggestions, just let us know. we await word from you with great interest. ss ii by now, kaiser had accepted what had happened to him. his distress and anxiety were gone and he was impatient to do what he could to establish better contact with his uninvited tenant. with eager anticipation, he set to thinking how it could be done. after a few minutes, an idea occurred to him. taking a small scalpel from a medical kit, he made a shallow cut in his arm, just deep enough to bleed freely. he knew that the pain would supply the necessary glandular reaction. the cut bled a few slow drops--and as kaiser watched, a shiny film formed and the bleeding stopped. that checked pretty well with the ship's theory. perhaps the symbiote had made his senses more acute. he tried closing his eyes and fingering several objects in the room. it seemed to him that he could determine the texture of each better than before, but the test was inconclusive. walking to the rear of the scout, he tried reading the printed words on the instrument panel. each letter stood out sharp and clear! kaiser wondered if he might not make an immediate, practical use of the symbiote's apparent desire to help him. concentrating on the discomfort of the high humidity and exaggerating his own displeasure with it, he waited. the result surprised and pleased him. the temperature within the scout cabin seemed to lower, the moisture on his body vanished, and he was more comfortable than he had yet been here. as a double check, he looked at the ship's thermometer. temperature 102, humidity 113--just about the same as it had been on earlier readings. * * * * * during the next twenty-four hours, kaiser and the mother ship exchanged messages at regular six-hour intervals. in between, he worked at repairing the damaged scout. he had no more success than before. he tired easily and lay on the cot often to rest. each time he seemed to drop off to sleep immediately--and awake at the exact times he had decided on beforehand. at first, despite the lack of success in straightening the bent metal of the scout bottom, there had been a subdued exhilaration in reporting each new discovery concerning the symbiote, but as time passed, his enthusiasm ebbed. his one really important problem was how to repair the scout and he was fast becoming discouraged. at last kaiser could bear the futility of his efforts no longer. he sent out a terse message to the _soscites ii_: taking short trip to another location on river. hope to find more intelligent natives. could be that the settlement i found here is analogous to tribe of monkeys on earth. i know the chance is small, but what have i to lose? i can't fix scout without better tools, and if my guess is right, i may be able to get equipment. expect to return in ten or twelve hours. please keep contact with scout. smoky kaiser packed a mudsled with tent, portable generator and guard wires, a spare sidearm and ammunition, and food for two days. he had noticed that a range of high hills, which caused the bend in the river at the native settlement, seemed to continue its long curve, and he wondered if the hills might not turn the river in the shape of a giant horseshoe. he intended to find out. wrapping his equipment in a plastic tarp, kaiser eased it out the doorway and tied it on the sled. he hooked a towline to a harness on his shoulders and began his journey--in the opposite direction from the first native settlement. he walked for more than seven hours before he found that his surmise had been correct. and a second cluster of huts, and seal-people in the river, greeted his sight. he received a further pleasant surprise. this group was decidedly more advanced than the first! they were little different in actual physical appearance; the change was mainly noticeable in their actions and demeanor. and their odor was more subdued, less repugnant. by signs, kaiser indicated that he came in peace, and they seemed to understand. a thick-bodied male went solemnly to the river bank and called to a second, who dived and brought up a mouthful of weed. the first male took the weed and brought it to kaiser. this was obviously a gesture of friendship. the weed had a white starchy core and looked edible. kaiser cleaned part of it with his handkerchief, bit and chewed it. the weed had a slight iron taste, but was not unpalatable. he swallowed the mouthful and tried another. he ate most of what had been given him and waited with some trepidation for a reaction. * * * * * as dusk fell, kaiser set up his tent a few hundred yards back from the native settlement. all apprehension about how his stomach would react to the river weed had left him. apparently it could be assimilated by his digestive system. lying on his air mattress, he felt thoroughly at peace with this world. once, just before dropping off to sleep, he heard the snuffling noise of some large animal outside his tent and picked up a pistol, just in case. however, the first jolt of the guard-wire charge discouraged the beast and kaiser heard it shuffle away, making puzzled mewing sounds as it went. the next morning, kaiser left off all his clothes except a pair of shorts and went swimming in the river. the seal-people were already in the water when he arrived and were very friendly. that friendliness nearly resulted in disaster. the natives crowded around as he swam--they maneuvered with an otter-like proficiency--and often nudged him with their bodies when they came too close. he had difficulty keeping afloat and soon turned and started back. as he neared the river edge, a playful female grabbed him by the ankle and pulled him under. kaiser tried to break her hold, but she evidently thought he was clowning and wrapped her warm furred arms around him and held him helpless. they sank deeper. when his breath threatened to burst from his lungs in a stream of bubbles, and he still could not free himself, kaiser brought his knee up into her stomach and her grip loosened abruptly. he reached the surface, choking and coughing, and swam blindly toward shore until his feet hit the river bottom. as he stood on the bank, getting his breath, the natives were quiet and seemed to be looking at him reproachfully. he stood for a time, trying to think of a way to explain the necessity of what he had done, but there was none. he shrugged helplessly. there was no longer anything to be gained by staying here--if they had the tools he needed, he had no way of finding out or asking for them--and he packed and started back to the scout. kaiser's good spirits returned on his return journey. he had enjoyed the relief from the tedium of spending day after day in the scout, and now he enjoyed the exercise of pulling the mudsled. above the waist, he wore only the harness and the large, soft drops of rain against his bare skin were pleasant to feel. when he reached the scout, kaiser began to unload the sled. the tarpaulin caught on the edge of a runner and he gave it a tug to free it. to his amazement, the heavy sled turned completely over, spilling the equipment to the ground. perplexed, kaiser stooped and began replacing the spilled articles in the tarp. they felt exceptionally light. he paused again, and suddenly his eyes widened. * * * * * moving quickly to the door of the scout, he shoved his equipment through and crawled in behind it. he did not consult the communicator, as he customarily did on entering, but went directly to the warped place on the floor and picked up the crowbar he had laid there. inserting the bar between the metal of the scout bottom and the engine casing, he lifted. nothing happened. he rested a minute and tried again, this time concentrating on his desire to raise the bar. the metal beneath yielded slightly--but he felt the palms of his hands bruise against the lever. only after he dropped the bar did he realize the force he had exerted. his hands ached and tingled. his strength must have been increased tremendously. with his plastic coat wrapped around the lever, he tried again. the metal of the scout bottom gave slowly--until the fuel pump hung free! kaiser did not repair the tube immediately. he let the solution rest in his hands, like a package to be opened, the pleasure of its anticipation to be enjoyed as much as the final act. he transmitted the news of what he had been able to do and sat down to read the two messages waiting for him. the first was quite routine: reports from the octopus indicate that big muddy undergoes radical weather-cycle changes during spring and fall seasons, from extreme moisture to extreme aridity. at height of dry season, planet must be completely devoid of surface liquid. to survive these unusual extremes, seal-people would need extreme adaptability. this verifies our earlier guess that natives have symbiosis with the same virus form that invaded you. with symbiotes' aid, such radical physical change could be possible. will keep you informed. give us any new information you might have on natives. ss ii the second report was not so routine. kaiser thought he detected a note of uneasiness in it. suggest you devote all time and effort to repair of scout. information on seal-people adequate for our purposes. ss ii kaiser did not answer either communication. his earlier report had covered all that he had learned lately. he lay on his cot and went to sleep. in the morning, another message was waiting: very pleased to hear of progress on repair of scout. complete as quickly as possible and return here immediately. ss ii * * * * * kaiser wondered about the abrupt recall. could the _soscites ii_ be experiencing some difficulty? he shrugged the thought aside. if they were, they would have told him. the last notes had had more than just a suggestion of urgency--there appeared to be a deliberate concealing of information. strangely, the messages indicated need for haste did not prod kaiser. he knew now that the job could be done, perhaps in a few hours' time. and the _soscites ii_ would not complete its orbit of the planet for two weeks yet. without putting on more than the shirt and trousers he had grown used to wearing, kaiser went outside and wandered listlessly about the vicinity of the ship for several hours. when he became hungry, he went back inside. another message came in as he finished eating. this one was from the captain himself: why have we received no verification of last instructions? repair scout immediately and return without further delay. this is an order! h. a. hesse, capt. kaiser pushed the last of his meal--which he had been eating with his fingers--into his mouth, crumpled the tape, wiped the grease from his hands with it and dropped it to the floor. he pondered mildly, as he packed his equipment, why he was disregarding the captain's message. for some reason, it seemed too trivial for serious consideration. he placated his slightly uneasy conscience only to the extent of packing the communicator in with his other equipment. it was a self-contained unit and he'd be able to receive messages from the ship on his trip. * * * * * the tracks of his earlier journey had been erased by the soft rain, and when kaiser reached the river, he found that he had not returned to the village he had visited the day before. however, there were other seal-people here. and they were almost human! the resemblance was still not so much in their physical makeup--that was little changed from the first he had found--as in their obviously greater intelligence. this was mainly noticeable in their facile expressions as they talked. kaiser was even certain that he read smiles on their faces when he slipped on a particularly slick mud patch as he hurried toward them. where the members of the first tribes had all looked almost exactly alike, these had very marked individual characteristics. also, these had no odor--only a mild, rather pleasing scent. when they came to meet him, kaiser could detect distinct syllabism in their pipings. most of the natives returned to the river after the first ten minutes of curious inspection, but two stayed behind as kaiser set up his tent. one was a female. they made small noises while he went about his work. after a time, he understood that they were trying to give names to his paraphernalia. he tried saying "tent" and "wire" and "tarp" as he handled each object, but their piping voices could not repeat the words. kaiser amused himself by trying to imitate their sounds for the articles. he was fairly successful. he was certain that he could soon learn enough to carry on a limited conversation. the male became bored after a time and left, but the girl stayed until kaiser finished. she motioned to him then to follow. when they reached the river bank, he saw that she wanted him to go into the water. * * * * * before he had time to decide, kaiser heard the small bell of the communicator from the tent behind him. he stood undecided for a moment, then returned and read the message on the tape: still anxiously awaiting word from you. in meantime, give very close attention to following. we know that the symbiotes must be able to make radical changes in the physiology of the seal-people. there is every probability that yours will attempt to do the same to you--to better fit your body to its present environment. the danger, which we hesitated to mention until now--when you have forced us by your obstinate silence--is that it can alter your mind also. your report on second tribe of seal-people strongly indicates that this is already happening. they were probably not more intelligent and humanlike than the others. on the contrary, you are becoming more like them. danger acute. return immediately. repeat: immediately! ss ii kaiser picked up a large rock and slowly, methodically pounded the communicator into a flattened jumble of metal and loose parts. when he finished, he returned to the waiting girl on the river bank. she pointed at his plastic trousers and made laughing sounds in her throat. kaiser returned the laugh and stripped off the trousers. they ran, still laughing, into the water. already the long pink hair that had been growing on his body during the past week was beginning to turn brown at the roots. a complete edition of the works of nancy luce, of west tisbury, dukes

nancy luce. god's words. the lord has put down in the bible; he says: the sin in the world,- it grieves him to his heart. the lord he forbiddeth all cruelty to dumb creatures, and helpless human too. he will cut the sinners asunder hereafter. god says: "ye shall not afflict any helpless or fatherless child. if thou afflict them in any wise, and they cry at all unto me, i will surely hear their cry." human, they cannot get into heaven, without they do god's commandments, in deeds, words, and thoughts, to human, and dumb creatures too. consider how you would feel yourselves to be crueled. the greatest sin is to cruel the poor harmless dumb creatures, they cannot speak, nor help themselves, the next sin is to cruel sick human, the next sin is to cruel any who cannot help themselves. the lord give human his word, to do justice to the afflicted and needy, to all poor sufferers, human and dumb creatures too, to be tender and kind to all. o may our sympathizing hearts, in generous pleasures know, kindly to share in others' joy, and weep for others' woe. o charity, thou heavenly grace, all tender, soft and kind; a friend to all the living race, to all that's good inclined. the lord takes pleasure in them, which will not hurt dumb creatures, nor human, in not any way whatever, have holy hearts, tender and kind. the wicked shall their triumph see, and gnash their teeth in agony, they and their envy, pride, and spite, sink down to everlasting punishment. the full rank of evil one wants all to be cruel, to the poor harmless dumb creatures, and cruel to sick human too, and take the advantage and cruel all. the full rank of evil one wants all to be murders, and lie, rob, cheat, and steal, and deceit, and contraryness, and so on, and plague every body they can. the good god of heaven, will cast off such sinners, to their double rank, punishment hereafter. poor thoughtless sinners, going on in sin, minding the evil one, their punishment they will have hereafter. god has given human his word, to have no evil conduct, and no evil speaking, and no evil thoughts. god wants all to be tender and kind, soft be our hearts, their misery to feel, and swift our hands to aid. this world a place of misery, some of the worst of sinners have destroyed my head, i cannot bear it up, o my misery, their heart is made of stone, to do such a thing. o lord, my god of heaven, i pray for thy holy spirit to go in all the needy hearts in the whole wide world around. o that they may be tender and kind to all the poor harmless dumb creatures, and sick human too, and others too. the sinners will have their punishment according to their sins, if they will not have the holy spirit. o lord, my god of heaven, i pray thee, enable me what to do, and what to say, and what to think, day after day. o lord, my god, be with me. love god with all your soul and strength, with all your heart and mind, be faithful, just, and kind, have tender feelings in your heart. deal with another as you'd have another deal with you, what you're unwilling to receive be sure you never do. the wicked shall see it, and grieve away, and gnash with their teeth, and melt away, the desire of the wicked shall perish away, and away they will go, to punishment great. they slay the helpless, they murder the fatherless, god will hold up the fatherless child, if it is his own. o god, the father of the fatherless, have mercy on me, deliver me from the wicked. god says, depart from evil, and good they must do. prepare ye the way of the lord, and make your paths straight. be ye therefore merciful, as your father in heaven also is merciful. thus saith the lord of hosts: turn ye now from your evil ways, and from your evil doings. thus saith the lord of hosts; consider your ways. i am cast down to the dust of the earth, with trouble, trials, and sickness, i am grieved to my heart for sin in the world, for the poor harmless dumb creatures, and for the best human too. * * * * * lines composed by nancy luce about poor little tweedle tedel beebee pinky, when she was a little chicken. and you will find more reading in the book about her. when poor little heart pinky, was about six weeks old, she was taken with the chicken distemper, chickens died off all over this island. she was catching grasshoppers, and crickets, in the forenoon smart, at twelve o'clock she was taken sick, and grew worse. at one o'clock she was past opening her eyes, and could not stand, her body felt cold and stiff to my hand. i give her a portion of epsom salts, with a little black pepper in it, i wept over her that afternoon, i prayed to the lord to save me her life. i sat up that night, with her in my lap, till eleven o'clock that night, then she seemed to be better. then i put her in a thing, a good soft bed, and lay down and spoke to her often, say how do you do, little dear, she answered me quick, then i knew she was better. the next day i gave her warm water to drink, the third day she was herself, got well and smart. she remained well four years, and laid me pretty eggs, then the lord thought best to take her from the evil to come, without being sick but a very little while. when i was raising poor little dear in my lap, and it rained on the window, she would look at the rain, and put her head under my cape. and take it out every once in a while, and look at the rain, and put it under my cape again, up most to my shoulder. poor cunning little dear, my heart is broken for her, she and i loved each other so well, and she had more than common wit. that dear little heart, remembered four years, ever since she was a little chicken, i know it by many things. her dear friend is left in trouble, and undergo sickness too. them that knew me once, know--me--no--more, her death renewed me to seek for god, to land in heaven hereafter. nancy luce west tisbury, dukes county, mass., 1872. prayer. hear my prayer, o lord, my god of heaven, grant me i beseech thee, o lord, send thy holy spirit into all the needy hearts, in the whole wide world around, convince them of sin, give them the holy spirit, o that they may be kind and tender to the poor harmless dumb creatures, they cannot speak, nor help themselves, o lord, prepare the inhabitants of the earth to live in this world and in the world to come. o lord, i beseech thee, protect me from committing sin, o lord, help me to watch and pray, o lord, i give thee thanks for what blessings i have, o lord, can thou deliver me from sickness, trouble and trials? o lord, stand my friend in this world and in the world to come. o lord, that the professing inhabitants may not fall back and go to sinning again. o that they may be true christians, the holy spirit, love and tender kindness for dumb creatures and human too, love god and land in heaven, o lord, enable me to have the holy spirit all the days of my life, o lord, grant me i beseech thee, i pray for thy kingdom to come, to destroy all sin, for the poor harmless dumb creatures, and for sick human too. and for all the troubled in the wide world round, human and dumb creatures too, for thine is the kingdom and the glory forever. amen. sickness. sickness distressing, by trouble and trials, walk, stir, or do a little in the house, it hurts me very bad, and i cannot ride to have comfort. my head a misery place all of my time, and part of my time in great misery, and noise sets my head in a dreadful condition. most nothing hurts me, and most nothing beats me out, i am dreadful worn down with long sickness, and trials, and sometimes trouble too. sick i do feel all my whole time, and misery feelings from head to feet. a number of years, i have undergone great sickness. some of my diseases are cured a few years ago, and some of them helped some, and some of them patched along, and some of them not any better at all, but i am dreadful wore down with long sickness. a common thing in my sickness, milk my cow, take care of my hens, in such misery, i felt as if i must fall at every step, but i must do it, i must do it. oh, thou who dry'st the mourner's tear, how dark this world would be. if when deceived and wounded here, we could not fly to thee. when sore afflictions press me down, i need thy quickning powers, thy word that i have rested on, shall help my heaviest hours. poor little hearts. a sketch of two poor little banties, they died with old age, over twelve years ago, poor little ada queetie died over thirteen years ago, in 1858. poor little beauty linna died over twelve years ago, in 1859. o my poor deceased little ada queetie, she knew such a sight, and her love and mine, so deep in our hearts for each other, the parting of her and her undergoing sickness and death, o heart rending! she and i could never part, do consider the night i was left, what i underwent, no tongue could express, weeping the whole night through. poor little ada queetie's sickness and death, destroyed my health at an unknown rate, with my heart breaking and weeping, i kept fire going night after night, to keep poor little dear warm, i kept getting up nights to see how she was, and see what i could do for her. three her last days and nights, she breathed the breath of life here on earth, she was taken down very sick, then i was up all night long, the second night i was up till i was going to fall, then i fixed her in her box warm, close by the fire, put warm clothes under, over and around, and left fire burning and lay down, with all my clothes on, a very little while, and got up and up all the time. the third night i touched no bed at all, poor little heart, she was struck with death at half past eleven o'clock. she died in my arms at twelve o'clock at night, o heart rending! i could been heard to the road, from that time till daylight, no tongue could express my misery of mind. she had more than common wit, and more than common love, her heart was full of love for me, o do consider my poor little heart. she was my dear and nearest friend, to love and pity me, and to believe that i was sick, she spoke to me, and looked at me most all the time, and could not go from me. poor little heart, she used to jump down to the door to go out, she would look around, and call to me to go with her, she found i could not go, she would come in again, she loved her dear friendy so well she could not go out and leave me. o my dear beloved little heart, she was my own heart within me, when she was well and i was sick, and made out to sit in my chair, she knew i was sick, because i didn't say but a very little to her. she would stand close to me all the time, and speak to me, i could not take her eyes off my face, and look as grieved as it her heart must break, she was so worried for me, and if i was forced to lay down, then she was more worried than ever. when poor little heart happened to be out the room, and i was forced to lay down, she would come and peek at me, and take on, as if her heart must break, and come straight to me and lament my cause, and would not go from me, her feelings was so deeply rooted in her heart for me. they was brought from chilmark to new town, and remained there one year for me to get able to take care of them. and then they was brought to me. poor little ada queetie, she used to do everything i told her, let it be what it would, and knew every word i said to her. if she was as far off as across the room, and i made signs to her with my fingers, she knew what it was, and would spring quick and do it. if she was far off and i only spoke her name, she would be sure to run to me quick, without wanting anything to eat. she would do 54 wonderful cunning things, poor sissy would do 39, they would do part of them without telling, and do all the rest of them with telling. i use to dream distressing dreams, about what was coming to pass, and awoke making a dreadful noise, and poor little ada queetie was making a mournful noise, she was so worried for me, then i would speak to her and say: little dear, nothing ails you friendy. then she would stop and speak a few pretty words to me. she use to shake my cape, with all her strength and might, every time i told her, they would both put one foot into my hand, every time i told them, they would both scratch my hand, and peck on my cap, every time i told them. when some one used to happen to shut them out the room, they would take on at a dreadful rate, i let them straight in, and as soon as the person was gone, poor little ada queetie would not keep out of my lap, squeezing me close up, talking to me, and poor little beauty linna would not keep off my shoulders, with her face squeezed close to my face, talking to me, they was so glad they got back in this room with me, and i wasn't hurt and carried away. consider those dear hearts, that loved me so well, and depended all on me to be their true friend. poor little beauty linna, departed this life, my hands around her by the fire, my heart aching, i wept steady from that time, till next day, i took the best of care of her, days and nights, i did everything could be done, i did the best i could do, i sat up nights with her, till it made me very lame, then i fixed her in her bed, warm, close by the fire, put warm clothes under, over and around, and left fire burning and lay down with all my clothes on, and got up very often with her, and sat up as long as i could. i never took off none of my clothes for 18 days and nights. poor little heart, never can call me back no more, when i go out the room, she did it as long as she was able, for eight months after poor sissy's decease, she would not let me go out the room, called me straight back, as soon as i went out. i fed her with a teaspoon in her sickness, good milk and nutmeg, and good porridge, and so i did poor sissy. i made fire days and nights, to keep poor beauty linna warm, the day before poor little dear was taken away, she opened her eyes and looked me up into my face, for the last time, o heart melting, poor little beauty linna, she could not have the wind to blow on her, all her last summer through, she would keep out the wind. a mournful scene it was to me, to see their breath depart, consider soon my time will come, and i must follow on. anxiety of mind will keep any one up and doing, if they have a friend sick, if their own health is very miserable. no one here on earth can know, but only them that knows, how hard it is to undergo trouble and sickness. when i am taken away, i must be buried to the east side, of my poor little dears' graves. poor little beauty linna, she remembered poor sissy, for eight months after poor sissy's decease, i know it by many things. they would always have the best of good cake, and best of good wheat, brought from the west. when they was both alive, and i had fire in the north room, and it came up too cold for them, they would go in the east room, and call me to come to them, they would stand side and side, and look at the fire place, and look at me, deaning me to make fire there for them, then i would make fire there, and they and i sat down together, now they are gone and i am left broken hearted. when poor little ada queetie departed this life, that was the first cause of my seeking for god. the path of sorrow, and that path alone, leads to the land where sorrows are unknown. the sick, the troubled, god hears when they complain, and all the sons of grief, with tender heart, delights to bless, and love to give relief. it is not every one that says, lord, lord, that can enter the kingdom of heaven, it is them that doeth god's commandments, in deeds, words, and thoughts, to human and dumb creatures too, and love god and hate the evil one. milk. you needn't talk against milk, if you make your victuals of water, what you put with water won't go half so far, and awful eating and distress ailing folks, and no nourishment to it. make your victuals of milk, and what you put with milk will go twice as far, and good eating and nourishment to it. milk is cooling to health, and strengthening, other victuals distress my stomach, because i am out of health; milk agrees with me, other victuals distress me. i cannot eat bread, &c., i must have milk to live on or go without eating till i die. no comfort. you don't know how hard it is to me, because i cannot ride somewhere, i cannot ride nor walk out, impossible yet, i used to ride once in a while, on a canter, galop, and run, o what comfort that was. i have had horses to run with me, so that the ground looked all in black and white streaks. there never was a horse that ever started me from their back, now i am deprived from all comforts of life. poor, sick i, days are very dark, to undergo sickness, and no comforts of life, i hope to have comfort in heaven. o how much better to go to house of mourning, than to go to house of plays and frolicking, sorrow is better than laughter, by sadness of the countenance the heart is made better. o how i love the holy law, 'tis daily my delight, and thence my meditations draw, divine advice by night. touched with sympathy within, christ knows our feeble frame, he knows what sore temptations mean, for he has felt the same. restraining prayer we cease to fight, prayer makes the christian's armor bright, and satan trembles when he sees, the weakest saint upon his knees. afflictions, though they seem severe, in mercy oft are sent, they stopped the prodigal's career, and forced him to repent. prayer makes the darkened cloud withdraw, prayer climbs the ladder jacob saw, gives exercise to faith and love, brings every blessing from above. the lord will sustain our weakest powers, with his almighty arm, and watch our most unguarded hours, against surprising harm. poor, weak, and worthless though i am, i have a rich, almighty friend, jesus, the saviour, is his name, he freely loves and without end. human, god is love and truth, god requires human to consider dumb creatures, what a site of wit they have got, and what a site of love they have got for one another, and love for human too, if they are kind to them, if human are cruel to dumb creatures in any way, or let them suffer in any way, god will cast off such sinners, to everlasting punishment. god requires human to take it to their own case, if they was dumb creatures, could not speak, nor help themselves, and human crueled them in any way, or let them suffer in any way. consider what you would undergo to be crueled, if you could not help yourselves. god requires human to leave off all their sins, and pray to the lord with truth, to take away their heart of stone, and give them a good heart, the holy spirit, prepare them to both live, and die, without true repentance, they will go to punishment, according to their sins, the thoughts are the ground work of all sin, and ground work of all goodness too, if any one is cruel to dumb creatures, they cannot get into heaven, they have not love of god in their hearts, they will go to punishment hereafter. prayers. our father in heaven, o lord, grant me i beseech thee, send thy holy spirit to all the wicked inhabitants in this world, that they may see the evil of their ways, and have the holy spirit, true christians, love and tenderness for the poor harmless dumb creatures, and human too, love and serve the lord all their days, and land in heaven hereafter. o that the professing inhabitants may not fall back, and go to sinning again, o that they may be true christians, the holy spirit, love and tenderness for the poor harmless dumb creatures, and human too, love and serve the lord all their days, and then land in heaven, o grant me i beseech thee, enable me to have the holy spirit all my days, and not fall back, and love and serve the lord all the days of my life, then land in heaven. o lord protect me from committing sin, o lord, help me to watch, and pray, o lord, enable me to put my whole trust in thee, that i may be protected from all harm in this world, and in the world to come, o lord, i beseech thee, help me through this world of misery, and land me in heaven, where no sickness, no trouble, no trials, distress me no more, come quickly, lord jesus, come, and put a stop to all sin, thy kingdom come, thy will be done on earth as it is done in heaven, for thine is the kingdom, the power and the glory forever. amen. this world a place of misery, i am grieved to my heart, for sin in the world. blessed are the merciful: for they shall obtain mercy. blessed are they which are persecuted for righteousness sake: for theirs is the kingdom of heaven. the lord give human his word to do justice to the afflicted and needy, to all the poor sufferers, human, and dumb creatures too, to be kind, and tender to all. god forbiddeth all profaning of any thing, thereby god maketh himself known. god says, all the horns of the wicked will be cut off, but the horns of the righteous will be exalted. hear my prayer, o lord, my god of heaven, and let my cry come unto thee, grant me i beseech thee, o lord, send thy holy loving kindness into the whole wide world around, and protect all the poor harmless dumb creatures from all cruelty till the world ends, o that i may praise thee for thy holy loving kindness, as long as i have breath to breathe. o lord, i beseech thee, send thy holy loving kindness and protect me from all cruelty, from the wicked, as long as i live. o there i may praise thee as long as i live. o lord, grant me, i beseech thee, send thy holy loving kindness and protect all the good folks from cruelty from the wicked, till the world ends. o that i may praise thee as long as i live. o lord, land me in the best place in heaven. o deliver me from sickness, trouble, trials. the lord is nigh unto them that call upon him in truth. o god, my heart is fixed, i will praise thee. the lord will maintain the cause of the afflicted. the lord is righteous, he will cut asunder the cords of the wicked. amen. poor little heart. poor tweedle, tedel, bebbee, pinky. she is gone. she died june 19th, 1871, at quarter past 7 o'clock in the evening, with my hands around her, aged 4 years. i never can see poor little dear again. poor pinky, that dear little heart, she is gone, sore broke in her, died in distress, poor little heart, o it was heart rending. o sick i do feel ever since, i am left broken hearted, she was my own heart within me, she had more than common wit. poor pinky's wit, and she loved me so well, them was the reasons, i set so much by her, and i raised her in my lap too. she is taken from the evil to come, if i had died and left her, she would mourn for me, and suffer, and die for me. i wept all that night, and by spells ever since, to god i cried, he supported me, god has held me up, through all my trials, and all i have to lean upon, in every cause. if i had died and left her, to mourn, and suffer, and could have known i should die and leave her, i should have felt a great deal worse to leave her, than i do now, that she is gone before me. i must be as reconciled as i can, to part with poor little dear, all i have to comfort me is, she is taken from the evil to come. i hope i never shall have a hen, to set so much by again, from over sea, she was brought to me, one week old, i raised her in my lap, she loved me dreadful dearly. she would jam close to me, every chance she could get, and talk to me, and want to get in my lap, and set down close. and when she was out from me, if i only spoke her name, she would be sure to run to me quick, without wanting anything to eat. she placed her whole affections on me; when she was alive, and saw me to the east window, she would put her head through the pickets, and look at me, as long as she could see my face. she had more wit than any hen i ever knew, poor, sweet little dear, down in her silent grave, turning to dust, o heart rending, i never can see her again. god is supporting me under my trouble, he took away my dear friend, he has done it for the best, it is all right and just. but o it was heart rending, for that poor little heart, to undergo death, and for me to part with her. when overwhelmed with grief, my heart within me dies, helpless, and far from all relief, to heaven i lift my eyes. this world a place of misery, o lord land me in heaven, that holy, happy place, when i bid adieu to this vain world. blessed are they, which have feelings to melt, for the poor harmless dumb creatures, and for sick human too. and for all the troubled, in the wide world around, human and dumb creatures too, great sympathy and love, they will have from the lord. i must be as reconciled as i can, to part with poor little dear, it is all for the best, from the evil to come. she was sick and died very sudden, only two hours and a quarter, about fifteen minutes dying. bloody water pouring out her mouth, and her breath agoing, poor little heart. o dreadful melancholy i do feel for my dear, she laid eggs till three days before her death, she laid the most eggs, this four years around, than any hen i have on earth. soon my turn will come, and i must follow on, i hope to land on that blest shore, where no sickness, no trouble, no trials, distress me no more. my heart is fix'd on thee, my god, i rest my hope on thee alone, christ wept so much himself, he counts, and treasures up my tears. prayer an answer will obtain, through the lord a little delay; none shall seek his name in vain, none be empty sent away. the lord takes pleasure in the just, whom sinners treat with scorn, the meek, that lie despised in dust, salvation shall adorn. blest are the meek who stand afar, from rage and passion, noise and war, god will secure their happy state, and plead their cause against the great. to god i cried when troubles rose, he heard me and subdued my foes, he did my rising fears control, and strength diffused through all my soul. consider how distressing sickness is to undergo, and how distressing in many ways, my parents' sickness, a number of years, caused them to sell cows, oxen, horses, and sheep, english meadow, clear land, and wood land, consider how distressing sickness is in many ways. our saviour's golden rule. be you to others kind and true, as you'd have others be to you, and never do nor say to them, whate'er you would not take again. hen's names.

doctor hens, they doctor them wrong, it hurts them, and it is dreadful cruel to let them die. it is as distressing to dumb creatures to undergo sickness, and death, as it is for human, and as distressing to be crueled, and as distressing to suffer. god requires human to take good care of dumb creatures, and be kind to them, or not keep any. now do understand, and i will tell you exact. stoppage in stomach.--if a hen has stoppage in her stomach, her corn stops in her crop, hard and swell large, and she sick, first work with your fingers carefully, get it soft, then take a small teaspoon and measure it full of epsom salts, and dissolve it in water, and give it to her with a teaspoon; you must keep to work with your fingers often, to keep it from hardening again, and the next day, if her breath smells bad, there is a rottenness in her stomach, then give her most as much of epsom salts again. put a little flour porridge in her mouth with a teaspoon, three times a day, and a little soaked cracker, soaked in water; put a little in her mouth if she can swallow it, in five days she eat with the hens and be well. this is the way i cure them. folks bring hens to me in this disease, to the point of death, been sick a long time, i cure them in five days; they must not have any milk in this disease, it will kill them, do as i tell you and you can cure them. once in a great while one of my hens have stoppage in their stomach; i cure them with only my fingers, because i take her as soon as the corn stops. milk does not agree with hens in sickness nor health, it keeps up in their stomach, and they vomit it up. i think strange it does not agree with hens, because milk is so good for human. you must not give your hens any castor oil, nor rhubarb, in not any disease whatever; it is poison for them, my reason tells me so, and i hear of folks killing their hens by giving them such stuff. my hens all keep healthy, because i keep them clean, and keep victuals and clean water standing by them, and take good care of them. i can cure a good many diseases for hens, but i cannot cure every disease. every once in a while a sick hen is brought to me, to the point of death, been sick a great while, most dead, some ail one disease, some ail a number of diseases; i receive them into my care, i doctor them, and take care of them, i raise them up to health, i am unable to do anything, but i must take pity. froth in throat.--if a hen has froth in her throat and crop, measure a small teaspoonful of epsom salts, dissolve it, put in a little black pepper, and give it to her with a teaspoon, it will cure this disease; but if she make a screaming noise with it, and distressed with it, then a sore growing in her, then no cure. gapes.--if a hen or chicken gapes a great deal, and sick, and complains of her throat, make pills of black pepper, cream, white flour, and put a pill in her mouth and make her swallow it till she takes down enough; the black pepper kills the worms. i cure them so. bag stone.--this is a seldom case, i have known this case once in a while. if a hen has a bag of stones grow in her, hang down under her, you must give her the best of good cake to eat, the stones will consume in a few weeks, then she will eat corn and oats with the hens, and lay you eggs; but if you do not give her the best of cake she will certainly die, she cannot eat anything else then, in this disease, but best of cake. i cured them so. skin in hen.--if a hen goes on her nest, and try to lay an egg, and cannot, and there most all day, then a skin of an egg is in her, she will certainly die if the skin of egg is not took out of her; some one has a small finger, and common sense, take the skin of egg out of her, then she is all right. i cure them so. bones.--if a hen is wounded in her hips, or any of her bones, bathe freely with mcquesten's extractor a number of times every day, put on a good deal, till she gets well; i have cured a number of hens with this extractor, they could not stand nor walk, their bones was so spraint, and so wrenched, &c. if their bones stiff too, then put on dr. job sweet's sprain liniment, if any sore, then put on castile soap. i cure them so. wild.--i bought a young hen last year, she was dreadful wild, and when one week was at an end she came to me, and let me take her up, she keep still, and eat out of my hand, she remains gentle ever since, and a good hen to lay eggs. green.--if a hen has bright green come from her, look same as bright green paint, with yellow in it, give her rice water with nutmeg grated in it, and jamaica ginger, a number of times a day, till it cures this disease. i cure them in a few days. feeling.--it is your duty to take good care, and not let anything hurt your hens, consider dear little hens. birds.--when i step down to the door, the little harmless birds come fly down on the ground, only one yard off my feet, and some of them half a yard off my feet. i give them oats and dough to eat; they eat it. will they come to any one else? so few folks have feeling. diarrhoea.---if a hen has diarrhoea, and pain with it, you must be as careful about what she eats, as her medicines; she must not have not any corn, and not any corn meal dough, not till she is well. give her a little warm flour porridge, five times a day, with a teaspoon; her medicine, jamaica ginger, put in warm rice water, and grate in good deal nutmeg, give it to her three times a day, take good care of her, and she get well. i cure them so. lice.--human, some of them, have lice on their hens, it is cruel, the reason is, the hen-house above the ground, and keep dirty, that breeds lice on hens, and breeds diseases too; have a cellar for your hens, and take up the dressing every morning, be no lice, lice will not breed in a cellar, i never have any lice on my hens, and they keep healthy. folks bring sick hens to me, i cure them, and lice on them too, i put black pepper in their feathers, it kills the lice. god meant for human to take good care of dumb creatures, and be kind to them, or not keep any. do by dumb creatures as you would wish to be done by if you was dumb creatures, consider how you would feel. cows.--meal is good for cows, but it will not do for her to have it dry, it gets in her nose and lungs, and hurt her, wet it; the best way is to scald it, and cool it, does more good. cracked corn is better; boil it, put on cover, it steams it soft very soon, one quart makes two and a half. cows must not have dusty hay, it hurts their lungs, &c. cows ought not to have timothy herds grass hay, it is physic. hay ought to be wet. warped neck.--if a hen has warped neck, rub on castor oil, faithful, a number of times, and give her a little huile d'olive to take inside, a good chance, her neck come in place again. swelled head.--if a hen has swelled head and face, and blue black, put on huile d'olive, i had one so, i cured her. fever.--if a hen has a fever, and her crop swelled soft, take a small teaspoon full of epsom salts and dissolve it in warm water, and put in a little black pepper in it, and give it to her with a teaspoon, and give her as much warm water as she wants to drink in her sickness, i cure hens and chickens so in three days, and give her a little porridge with a teaspoon, five times a day, till she is able to eat. i cure them so. feeling.--if any one is cruel to dumb creatures, they will go to everlasting punishment, and have the greatest punishment. sick, i am, and very unable to do anything, but i must take pity,--dear little hens. * * * * * god is good, love and truth, merciful in all his ways. if the will of god could be done in full, it would be a great happiness among dumb creatures and human too. cruelty is of the evil one. the good god is looking down upon such folks; he will cast them off to everlasting punishment. human must do god's commandments in deeds, words and thoughts. be kind to poor hens in every way, and not let them suffer with hunger nor cold; cruelty not in any way; must not affrighten them; doctor them when they have diseases. be good and kind to them. think how good god is. act up to his will in all your ways and all your thoughts too. you must keep your hens from suffering with cold, and give them enough to eat, and keep them clean, and not affrighten them, &c., &c., or they cannot lay you eggs. if your hens or chickens have their crops swelled soft, and a fever, give them a portion of epsom salts, with a little black pepper in it, and give them as much warm water as they can drink; in their sickness take good care of them, they get well. if they have stoppage in their stomach, their crop swelled hard, take your fingers and jam carefully till their crop is soft, then give them a portion of epsom salts. i have cured them with only my fingers, they get well. if they have itching feet and scurfy, if mutton tallow will not cure it, then put their feet in a thing of warm water and wash them every morning till they get well. when they shed their feathers, their stomach is weak then, they must have soft victuals then, hard corn will distress their stomach then. if hen's body comes out, put it back in her and see to her, she be well by the next day. if it comes more than half way out, it can be put back if any one has common sense. if a string of hen's insides comes out, with a egg fast to it, break the egg, and take it off from her insides and put her insides back in her and see to her, she be well by the next day. if hen's legs chilled with cold for want of sun, and they cannot walk, take them by the fire and rub their legs and feet, faithful, half a day, then rub on black pepper mixed with warm water, they get well. if a hen is starved she must not have hard corn at first, give her flour bread soaked soft in milk, till she is able to eat corn. hens must not go in snow, it hurts them. they must not have fat meat. they must not be crowded, their room must be large enough. their roosts must not be too high, for them to fly down on hard floor, it hurts their feet and hips. i know it. hens want sun in winter and shade in summer. if hens' feet crack, bleed, and sore places, melt mutton tallow and white sugar together, rub it on faithful, they get well. if they bleed great deal, put on warm alum water first, they get well. if hens' feet swell, put on sweet apple balsam every day, they get well. if hens' head turns over, give her epsom salts and black pepper, she get over it for a while. if hens have diarrhoea, give them boiled rice, black pepper, nutmeg, mixed, they get well if you take good care of them. hens must not have fish, it physics them. hens must not have anything relaxing. if hens have rattling in their throat give them epsom salts and black pepper, they get well. if hen has her head quiver, and stagger, give her epsom salts, and keep her quiet, and her food soak cracker in milk, she get well. if hens taken lame in the afternoon without being hurt, rub on mutton tallow and black pepper, they get well. if hen's bones spraint or bruised, bathe freely with mequesten's extracter, take good care of her, she get well in time, must have little time for it. this medicine will cure burns, scalds, on human, no doubt on hens too. it will cure sores, put it on when they first begin to come. if anything ails hens' eyes, rain-water is good, new milk put on, mutton tallow put around her eyes, salve made of rose water and cream, put around her eyes. hens must not be confined in wind, it hurts them, they cannot lay you eggs. god placed us in this world to be kind to dumb creatures, or not keep any, and kind to human too. consider what a wickedness it is to go contrary from it. i keep cow and hens, i do my duty for them. if hens have watery stomachs give them black pepper, put it in their dough, if they are able to eat it, if not able, then mix the pepper with water, and give it to her with a teaspoon, be careful and not have it too strong, to take her breath. if hens have pip, give them the same medicine, it will cure pip and watery stomach. help them in season. if hen has swelled throat, put on sweet oil and black pepper, she get well. you must not give your hens salt, it will kill them. you must not give them rye, it will hurt them. if hen lays soft shell eggs, let her set two or three weeks, she lay hard shell eggs again. you must take good care of your poor hens or they cannot lay you eggs. hens must be kept clean and must not have any bad smell with them, it will poison them. you must not give them cayenne pepper, it will poison them, it drives a redness into their heads, then they fail till they die. black pepper is good for them when they need it. hens must have clean victuals and clean water to drink. take the chill off the water in winter. keep good yellow southern corn standing by them, they take a little when they want it, it does them more good, and it takes less to keep them. give them boiled oats, it is good for them to lay eggs. i give my hens boiled oats all the time, and corn standing by them. i give them some other victuals too, sometimes, and sometimes i give them some boiled potatoes. i mash it with cream for them. my hens lay me more eggs than anybody's hens anywhere, by what i hear. good flour bread is splendid to make them lay eggs, but i am not able to cook it for them. the bread must not be sour. keep fine clam shells by them, and gravel sand. they must be kept warm in winter and cool in summer. they must have clean, warm cellar room, you will have double the eggs. take up the dressing every morning certain, and oftener, if they stay down there days. when cold, keep them in the cellar, when the weather is suitable, let them out days. if cold morning, keep them in till the sun gets up warm. be clever to them. they must not be affrighted. they can never get over it. i hear what folks do all my days, and their poor hens cannot lay much and they die off. it is wicked for folks to be so cruel. be good and kind to all that breathes, act up our good saviour's laws, have tender feelings in your hearts, for all the poor, harmless dumb creatures. my hens are all in better order since i had a cellar for them, than they were before, and lay me double the eggs. hens must not suffer with the cold, nor no other sufferings, you cannot have eggs. raise your chickens on good flour bread, it will make them healthy, grow fast and smart; they must be fed often; i do not think meal is very good for hens or chickens; meal is splendid for cows. if you are forced to give your hens or chickens meal, you must sift it fine and scald it and cool it. i used to raise my chickens on flour middlings dough, it is splendid for them. flour bread is better. i do not set any hens now. you must not let young chickens go in cold nor wet ground, nor rain, &c., &c. you must boil some corn in winter, and give it to your hens warm, besides other victuals. human, those that are cruel to dumb creatures and to human too, and murder, rob, steal, cheat, contrary, spite, deceit, and take the advantage of any one, to damage them in any way, &c., &c., those will go to everlasting punishment hereafter, and have the greatest punishment. be tender hearted, be kind one to another, do your duty to those who still live. god requires human to do as they wish to be done by, in deeds, words and thoughts, to human and dumb creatures too. the greatest sin is, in the sight of god, is to cruel the poor harmless dumb creatures, they cannot speak nor help themselves. the next sin is to cruel sick human, the next sin is to cruel any who cannot help themselves, and especially the cruel to the poor, harmless dumb creatures. the lord will cut asunder the cords of such sinners. this world a place of misery, i pray for thy kingdom to come, to destroy all sin, o lord, land me in heaven, that holy, happy place, when i bid adieu to this vain world, my good god in heaven, my only true friend, has held me up with his arm, and all i have to lean upon. christ, a man of grief, he wept so much himself, on him i lean, who not in vain, he counts and treasures up my tears. nancy luce. west tisbury, dukes county, mass., 1871. * * * * * this reading below is on my gravestones: poor little heart, ada queetie, o my

etext was produced from galaxy magazine february 1961. extensive research did not uncover any evidence that the u.s. copyright on this publication was renewed.] suddenly the biggest thing in the universe was the very tiniest. there were suns, which were nearby, and there were stars which were so far away that no way of telling their distance had any meaning. the suns had planets, most of which did not matter, but the ones that did count had seas and continents, and the continents had cities and highways and spaceports. and people. the people paid no attention to their insignificance. they built ships which went through emptiness beyond imagining, and they landed upon planets and rebuilt them to their own liking. suns flamed terribly, renting their impertinence, and storms swept across the planets they preëmpted, but the people built more strongly and were secure. everything in the universe was bigger or stronger than the people, but they ignored the fact. they went about the businesses they had contrived for themselves. they were not afraid of anything until somewhere on a certain small planet an infinitesimal single molecule changed itself. it was one molecule among unthinkably many, upon one planet of one solar system among uncountable star clusters. it was not exactly alive, but it acted as if it were, in which it was like all the important matter of the cosmos. it was actually a combination of two complicated substances not too firmly joined together. when one of the parts changed, it became a new molecule. but, like the original one, it was still capable of a process called autocatalysis. it practiced that process and catalyzed other molecules into existence, which in each case were duplicates of itself. then mankind had to take notice, though it ignored flaming suns and monstrous storms and emptiness past belief. men called the new molecule a virus and gave it a name. they called it and its duplicates "chlorophage." and chlorophage was, to people, the most terrifying thing in the universe. * * * * * in a strictly temporary orbit around the planet altaira, the _star queen_ floated, while lift-ships brought passengers and cargo up to it. the ship was too large to be landed economically at an unimportant spaceport like altaira. it was a very modern ship and it made the regulus-to-cassim run, which is five hundred light-years, in only fifty days of earthtime. now the lift-ships were busy. there was an unusual number of passengers to board the _star queen_ at altaira and an unusual number of them were women and children. the children tended to pudginess and the women had the dieted look of the wives of well-to-do men. most of them looked red-eyed, as if they had been crying. one by one the lift-ships hooked onto the airlock of the _star queen_ and delivered passengers and cargo to the ship. presently the last of them was hooked on, and the last batch of passengers came through to the liner, and the ship's doctor watched them stream past him. his air was negligent, but he was actually impatient. like most doctors, nordenfeld approved of lean children and wiry women. they had fewer things wrong with them and they responded better to treatment. well, he was the doctor of the _star queen_ and he had much authority. he'd exerted it back on regulus to insist that a shipment of botanical specimens for cassim travel in quarantine--to be exact, in the ship's practically unused hospital compartment--and he was prepared to exercise authority over the passengers. he had a sheaf of health slips from the examiners on the ground below. there was one slip for each passenger. it certified that so-and-so had been examined and could safely be admitted to the _star queen's_ air, her four restaurants, her two swimming pools, her recreation areas and the six levels of passenger cabins the ship contained. he impatiently watched the people go by. health slips or no health slips, he looked them over. a characteristic gait or a typical complexion tint, or even a certain lack of hair luster, could tell him things that ground physicians might miss. in such a case the passenger would go back down again. it was not desirable to have deaths on a liner in space. of course nobody was ever refused passage because of chlorophage. if it were ever discovered, the discovery would already be too late. but the health regulations for space travel were very, very strict. he looked twice at a young woman as she passed. despite applied complexion, there was a trace of waxiness in her skin. nordenfeld had never actually seen a case of chlorophage. no doctor alive ever had. the best authorities were those who'd been in patrol ships during the quarantine of kamerun when chlorophage was loose on that planet. they'd seen beamed-up pictures of patients, but not patients themselves. the patrol ships stayed in orbit while the planet died. most doctors, and nordenfeld was among them, had only seen pictures of the screens which showed the patients. * * * * * he looked sharply at the young woman. then he glanced at her hands. they were normal. the young woman went on, unaware that for the fraction of an instant there had been the possibility of the landing of the _star queen_ on altaira, and the destruction of her space drive, and the establishment of a quarantine which, if justified, would mean that nobody could ever leave altaira again, but must wait there to die. which would not be a long wait. a fat man puffed past. the gravity on altaira was some five per cent under ship-normal and he felt the difference at once. but the veins at his temples were ungorged. nordenfeld let him go by. there appeared a white-haired, space-tanned man with a briefcase under his arm. he saw nordenfeld and lifted a hand in greeting. the doctor knew him. he stepped aside from the passengers and stood there. his name was jensen, and he represented a fund which invested the surplus money of insurance companies. he traveled a great deal to check on the business interests of that organization. the doctor grunted, "what're you doing here? i thought you'd be on the far side of the cluster." "oh, i get about," said jensen. his manner was not quite normal. he was tense. "i got here two weeks ago on a q-and-c tramp from regulus. we were a ship load of salt meat. there's romance for you! salt meat by the spaceship load!" the doctor grunted again. all sorts of things moved through space, naturally. the _star queen_ carried a botanical collection for a museum and pig-beryllium and furs and enzymes and a list of items no man could remember. he watched the passengers go by, automatically counting them against the number of health slips in his hand. "lots of passengers this trip," said jensen. "yes," said the doctor, watching a man with a limp. "why?" jensen shrugged and did not answer. he was uneasy, the doctor noted. he and jensen were as much unlike as two men could very well be, but jensen was good company. a ship's doctor does not have much congenial society. the file of passengers ended abruptly. there was no one in the _star queen's_ airlock, but the "connected" lights still burned and the doctor could look through into the small lift-ship from the planet down below. he frowned. he fingered the sheaf of papers. "unless i missed count," he said annoyedly, "there's supposed to be one more passenger. i don't see--" a door opened far back in the lift-ship. a small figure appeared. it was a little girl perhaps ten years old. she was very neatly dressed, though not quite the way a mother would have done it. she wore the carefully composed expression of a child with no adult in charge of her. she walked precisely from the lift-ship into the _star queen's_ lock. the opening closed briskly behind her. there was the rumbling of seals making themselves tight. the lights flickered for "disconnect" and then "all clear." they went out, and the lift-ship had pulled away from the _star queen_. "there's my missing passenger," said the doctor. * * * * * the child looked soberly about. she saw him. "excuse me," she said very politely. "is this the way i'm supposed to go?" "through that door," said the doctor gruffly. "thank you," said the little girl. she followed his direction. she vanished through the door. it closed. there came a deep, droning sound, which was the interplanetary drive of the _star queen_, building up that directional stress in space which had seemed such a triumph when it was first contrived. the ship swung gently. it would be turning out from orbit around altaira. it swung again. the doctor knew that its astrogators were feeling for the incredibly exact pointing of its nose toward the next port which modern commercial ship operation required. an error of fractional seconds of arc would mean valuable time lost in making port some ten light-years of distance away. the drive droned and droned, building up velocity while the ship's aiming was refined and re-refined. the drive cut off abruptly. jensen turned white. the doctor said impatiently, "there's nothing wrong. probably a message or a report should have been beamed down to the planet and somebody forgot. we'll go on in a minute." but jensen stood frozen. he was very pale. the interplanetary drive stayed off. thirty seconds. a minute. jensen swallowed audibly. two minutes. three. the steady, monotonous drone began again. it continued interminably, as if while it was off the ship's head had swung wide of its destination and the whole business of lining up for a jump in overdrive had to be done all over again. then there came that "ping-g-g-g!" and the sensation of spiral fall which meant overdrive. the droning ceased. jensen breathed again. the ship's doctor looked at him sharply. jensen had been taut. now the tensions had left his body, but he looked as if he were going to shiver. instead, he mopped a suddenly streaming forehead. "i think," said jensen in a strange voice, "that i'll have a drink. or several. will you join me?" nordenfeld searched his face. a ship's doctor has many duties in space. passengers can have many things wrong with them, and in the absolute isolation of overdrive they can be remarkably affected by each other. "i'll be at the fourth-level bar in twenty minutes," said nordenfeld. "can you wait that long?" "i probably won't wait to have a drink," said jensen. "but i'll be there." the doctor nodded curtly. he went away. he made no guesses, though he'd just observed the new passengers carefully and was fully aware of the strict health regulations that affect space travel. as a physician he knew that the most deadly thing in the universe was chlorophage and that the planet kamerun was only one solar system away. it had been a stop for the _star queen_ until four years ago. he puzzled over jensen's tenseness and the relief he'd displayed when the overdrive field came on. but he didn't guess. chlorophage didn't enter his mind. not until later. * * * * * he saw the little girl who'd come out of the airlock last of all the passengers. she sat on a sofa as if someone had told her to wait there until something or other was arranged. doctor nordenfeld barely glanced at her. he'd known jensen for a considerable time. jensen had been a passenger on the _star queen_ half a dozen times, and he shouldn't have been upset by the temporary stoppage of an interplanetary drive. nordenfeld divided people into two classes, those who were not and those who were worth talking to. there weren't many of the latter. jensen was. he filed away the health slips. then, thinking of jensen's pallor, he asked what had happened to make the _star queen_ interrupt her slow-speed drive away from orbit around altaira. the purser told him. but the purser was fussily concerned because there were so many extra passengers from altaira. he might not be able to take on the expected number of passengers at the next stop-over point. it would be bad business to have to refuse passengers! it would give the space line a bad name. then the air officer stopped nordenfeld as he was about to join jensen in the fourth-level bar. it was time for a medical inspection of the quarter-acre of banthyan jungle which purified and renewed the air of the ship. nordenfeld was expected to check the complex ecological system of the air room. specifically, he was expected to look for and identify any patches of colorlessness appearing on the foliage of the jungle plants the _star queen_ carried through space. the air officer was discreet and nordenfeld was silent about the ultimate reason for the inspection. nobody liked to think about it. but if a particular kind of bleaching appeared, as if the chlorophyll of the leaves were being devoured by something too small to be seen by an optical microscope--why, that would be chlorophage. it would also be a death sentence for the _star queen_ and everybody in her. but the jungle passed medical inspection. the plants grew lushly in soil which periodically was flushed with hydroponic solution and then drained away again. the uv lamps were properly distributed and the different quarters of the air room were alternately lighted and darkened. and there were no colorless patches. a steady wind blew through the air room and had its excess moisture and unpleasing smells wrung out before it recirculated through the ship. doctor nordenfeld authorized the trimming of some liana-like growths which were developing woody tissue at the expense of leaves. the air officer also told him about the reason for the turning off of the interplanetary drive. he considered it a very curious happening. the doctor left the air room and passed the place where the little girl--the last passenger to board the _star queen_--waited patiently for somebody to arrange something. doctor nordenfeld took a lift to the fourth level and went into the bar where jensen should be waiting. he was. he had an empty glass before him. nordenfeld sat down and dialed for a drink. he had an indefinite feeling that something was wrong, but he couldn't put his finger on it. there are always things going wrong for a ship's doctor, though. there are so many demands on his patience that he is usually short of it. jensen watched him sip at his drink. "a bad day?" he asked. he'd gotten over his own tension. * * * * * nordenfeld shrugged, but his scowl deepened. "there are a lot of new passengers." he realized that he was trying to explain his feelings to himself. "they'll come to me feeling miserable. i have to tell each one that if they feel heavy and depressed, it may be the gravity-constant of the ship, which is greater than their home planet. if they feel light-headed and giddy, it may be because the gravity-constant of the ship is less than they're used to. but it doesn't make them feel better, so they come back for a second assurance. i'll be overwhelmed with such complaints within two hours." jensen waited. then he said casually--too casually, "does anybody ever suspect chlorophage?" "no," said nordenfeld shortly. jensen fidgeted. he sipped. then he said, "what's the news from kamerun, anyhow?" "there isn't any," said nordenfeld. "naturally! why ask?" "i just wondered," said jensen. after a moment: "what was the last news?" "there hasn't been a message from kamerun in two years," said nordenfeld curtly. "there's no sign of anything green anywhere on the planet. it's considered to be--uninhabited." jensen licked his lips. "that's what i understood. yes." nordenfeld drank half his drink and said unpleasantly, "there were thirty million people on kamerun when the chlorophage appeared. at first it was apparently a virus which fed on the chlorophyll of plants. they died. then it was discovered that it could also feed on hemoglobin, which is chemically close to chlorophyll. hemoglobin is the red coloring matter of the blood. when the virus consumed it, people began to die. kamerun doctors found that the chlorophage virus was transmitted by contact, by inhalation, by ingestion. it traveled as dust particles and on the feet of insects, and it was in drinking water and the air one breathed. the doctors on kamerun warned spaceships off and the patrol put a quarantine fleet in orbit around it to keep anybody from leaving. and nobody left. and everybody died. _and_ so did every living thing that had chlorophyll in its leaves or hemoglobin in its blood, or that needed plant or animal tissues to feed on. there's not a person left alive on kamerun, nor an animal or bird or insect, nor a fish nor a tree, or plant or weed or blade of grass. there's no longer a quarantine fleet there. nobody'll go there and there's nobody left to leave. but there are beacon satellites to record any calls and to warn any fool against landing. if the chlorophage got loose and was carried about by spaceships, it could kill the other forty billion humans in the galaxy, together with every green plant or animal with hemoglobin in its blood." "that," said jensen, and tried to smile, "sounds final." "it isn't," nordenfeld told him. "if there's something in the universe which can kill every living thing except its maker, that something should be killed. there should be research going on about the chlorophage. it would be deadly dangerous work, but it should be done. a quarantine won't stop contagion. it can only hinder it. that's useful, but not enough." jensen moistened his lips. nordenfeld said abruptly, "i've answered your questions. now what's on your mind and what has it to do with chlorophage?" jensen started. he went very pale. "it's too late to do anything about it," said nordenfeld. "it's probably nonsense anyhow. but what is it?" jensen stammered out his story. it explained why there were so many passengers for the _star queen_. it even explained his departure from altaira. but it was only a rumor--the kind of rumor that starts up untraceably and can never be verified. this one was officially denied by the altairan planetary government. but it was widely believed by the sort of people who usually were well-informed. those who could sent their families up to the _star queen_. and that was why jensen had been tense and worried until the liner had actually left altaira behind. then he felt safe. nordenfeld's jaw set as jensen told his tale. he made no comment, but when jensen was through he nodded and went away, leaving his drink unfinished. jensen couldn't see his face; it was hard as granite. and nordenfeld, the ship's doctor of the _star queen_, went into the nearest bathroom and was violently sick. it was a reaction to what he'd just learned. * * * * * there were stars which were so far away that their distance didn't mean anything. there were planets beyond counting in a single star cluster, let alone the galaxy. there were comets and gas clouds in space, and worlds where there was life, and other worlds where life was impossible. the quantity of matter which was associated with life was infinitesimal, and the quantity associated with consciousness--animal life--was so much less that the difference couldn't be expressed. but the amount of animal life which could reason was so minute by comparison that the nearest ratio would be that of a single atom to a sun. mankind, in fact, was the least impressive fraction of the smallest category of substance in the galaxy. but men did curious things. there was the cutting off of the _star queen's_ short-distance drive before she'd gotten well away from altaira. there had been a lift-ship locked to the liner's passenger airlock. when the last passenger entered the big ship--a little girl--the airlocks disconnected and the lift-ship pulled swiftly away. it was not quite two miles from the _star queen_ when its emergency airlocks opened and spacesuited figures plunged out of it to emptiness. simultaneously, the ports of the lift-ship glowed and almost immediately the whole plating turned cherry-red, crimson, and then orange, from unlimited heat developed within it. the lift-ship went incandescent and ruptured and there was a spout of white-hot air, and then it turned blue-white and puffed itself to nothing in metallic steam. where it had been there was only shining gas, which cooled. beyond it there were figures in spacesuits which tried to swim away from it. the _star queen's_ control room, obviously, saw the happening. the lift-ship's atomic pile had flared out of control and melted down the ship. it had developed something like sixty thousand degrees fahrenheit when it ceased to flare. it did not blow up; it only vaporized. but the process must have begun within seconds after the lift-ship broke contact with the _star queen_. in automatic reaction, the man in control of the liner cut her drive and offered to turn back and pick up the spacesuited figures in emptiness. the offer was declined with almost hysterical haste. in fact, it was barely made before the other lift-ships moved in on rescue missions. they had waited. and they were picking up castaways before the _star queen_ resumed its merely interplanetary drive and the process of aiming for a solar system some thirty light-years away. when the liner flicked into overdrive, more than half the floating figures had been recovered, which was remarkable. it was almost as remarkable as the flare-up of the lift-ship's atomic pile. one has to know exactly what to do to make a properly designed atomic pile vaporize metal. somebody had known. somebody had done it. and the other lift-ships were waiting to pick up the destroyed lift-ship's crew when it happened. the matter of the lift-ship's destruction was fresh in nordenfeld's mind when jensen had told his story. the two items fitted together with an appalling completeness. they left little doubt or hope. * * * * * nordenfeld consulted the passenger records and presently was engaged in conversation with the sober-faced, composed little girl on a sofa in one of the cabin levels of the _star queen_. "you're kathy brand, i believe," he said matter-of-factly. "i understand you've been having a rather bad time of it." she seemed to consider. "it hasn't been too bad," she assured him. "at least i've been seeing new things. i got dreadfully tired of seeing the same things all the time." "what things?" asked nordenfeld. his expression was not stern now, though his inner sensations were not pleasant. he needed to talk to this child, and he had learned how to talk to children. the secret is to talk exactly as to an adult, with respect and interest. "there weren't any windows," she explained, "and my father couldn't play with me, and all the toys and books were ruined by the water. it was dreadfully tedious. there weren't any other children, you see. and presently there weren't any grownups but my father." nordenfeld only looked more interested. he'd been almost sure ever since knowing of the lift-ship's destruction and listening to jensen's account of the rumor the government of altaira denied. he was horribly sure now. "how long were you in the place that hadn't any windows?" "oh, dreadfully long!" she said. "since i was only six years old! almost half my life!" she smiled brightly at him. "i remember looking out of windows and even playing out-of-doors, but my father and mother said i had to live in this place. my father talked to me often and often. he was very nice. but he had to wear that funny suit and keep the glass over his face because he didn't live in the room. the glass was because he went under the water, you know." nordenfeld asked carefully conversational-sounding questions. kathy brand, now aged ten, had been taken by her father to live in a big room without any windows. it hadn't any doors, either. there were plants in it, and there were bluish lights to shine on the plants, and there was a place in one corner where there was water. when her father came in to talk to her, he came up out of the water wearing the funny suit with glass over his face. he went out the same way. there was a place in the wall where she could look out into another room, and at first her mother used to come and smile at her through the glass, and she talked into something she held in her hand, and her voice came inside. but later she stopped coming. * * * * * there was only one possible kind of place which would answer kathy's description. when she was six years old she had been put into some university's aseptic-environment room. and she had stayed there. such rooms were designed for biological research. they were built and then made sterile of all bacterial life and afterward entered through a tank of antiseptic. anyone who entered wore a suit which was made germ-free by its passage through the antiseptic, and he did not breathe the air of the aseptic room, but air which was supplied him through a hose, the exhaled-air hose also passing under the antiseptic outside. no germ or microbe or virus could possibly get into such a room without being bathed in corrosive fluid which would kill it. so long as there was someone alive outside to take care of her, a little girl could live there and defy even chlorophage. and kathy brand had done it. but, on the other hand, kamerun was the only planet where it would be necessary, and it was the only world from which a father would land his small daughter on another planet's spaceport. there was no doubt. nordenfeld grimly imagined someone--he would have had to be a microbiologist even to attempt it--fighting to survive and defeat the chlorophage while he kept his little girl in an aseptic-environment room. she explained quite pleasantly as nordenfeld asked more questions. there had been other people besides her father, but for a long time there had been only him. and nordenfeld computed that somehow she'd been kept alive on the dead planet kamerun for four long years. recently, though--very recently--her father told her that they were leaving. wearing his funny, antiseptic-wetted suit, he'd enclosed her in a plastic bag with a tank attached to it. air flowed from the tank into the bag and out through a hose that was all wetted inside. she breathed quite comfortably. it made sense. an air tank could be heated and its contents sterilized to supply germ-free--or virus-free--air. and kathy's father took an axe and chopped away a wall of the room. he picked her up, still inside the plastic bag, and carried her out. there was nobody about. there was no grass. there were no trees. nothing moved. here kathy's account was vague, but nordenfeld could guess at the strangeness of a dead planet, to the child who barely remembered anything but the walls of an aseptic-environment room. her father carried her to a little ship, said kathy, and they talked a lot after the ship took off. he told her that he was taking her to a place where she could run about outdoors and play, but he had to go somewhere else. he did mysterious things which to nordenfeld meant a most scrupulous decontamination of a small spaceship's interior and its airlock. its outer surface would reach a temperature at which no organic material could remain uncooked. and finally, said kathy, her father had opened a door and told her to step out and good-by, and she did, and the ship went away--her father still wearing his funny suit--and people came and asked her questions she did not understand. * * * * * kathy's narrative fitted perfectly into the rumor jensen said circulated among usually well-informed people on altaira. they believed, said jensen, that a small spaceship had appeared in the sky above altaira's spaceport. it ignored all calls, landed swiftly, opened an airlock and let someone out, and plunged for the sky again. and the story said that radar telescopes immediately searched for and found the ship in space. they trailed it, calling vainly for it to identify itself, while it drove at top speed for altaira's sun. it reached the sun and dived in. nordenfeld reached the skipper on intercom vision-phone. jensen had been called there to repeat his tale to the skipper. "i've talked to the child," said nordenfeld grimly, "and i'm putting her into isolation quarters in the hospital compartment. she's from kamerun. she was kept in an aseptic-environment room at some university or other. she says her father looked after her. i get an impression of a last-ditch fight by microbiologists against the chlorophage. they lost it. apparently her father landed her on altaira and dived into the sun. from her story, he took every possible precaution to keep her from contagion or carrying contagion with her to altaira. maybe he succeeded. there's no way to tell--yet." the skipper listened in silence. jensen said thinly, "then the story about the landing was true." "yes. the authorities isolated her, and then shipped her off on the _star queen_. your well-informed friends, jensen, didn't know what their government was going to do!" nordenfeld paused, and said more coldly still, "they didn't handle it right. they should have killed her, painlessly but at once. her body should have been immersed, with everything that had touched it, in full-strength nitric acid. the same acid should have saturated the place where the ship landed and every place she walked. every room she entered, and every hall she passed through, should have been doused with nitric and then burned. it would still not have been all one could wish. the air she breathed couldn't be recaptured and heated white-hot. but the chances for altaira's population to go on living would be improved. instead, they isolated her and they shipped her off with us--and thought they were accomplishing something by destroying the lift-ship that had her in an airtight compartment until she walked into the _star queen's_ lock!" the skipper said heavily, "do you think she's brought chlorophage on board?" "i've no idea," said nordenfeld. "if she did, it's too late to do anything but drive the _star queen_ into the nearest sun.... no. before that, one should give warning that she was aground on altaira. no ship should land there. no ship should take off. altaira should be blocked off from the rest of the galaxy like kamerun was. and to the same end result." jensen said unsteadily; "there'll be trouble if this is known on the ship. there'll be some unwilling to sacrifice themselves." "sacrifice?" said nordenfeld. "they're dead! but before they lie down, they can keep everybody they care about from dying too! would you want to land and have your wife and family die of it?" the skipper said in the same heavy voice, "what are the probabilities? you say there was an effort to keep her from contagion. what are the odds?" "bad," said nordenfeld. "the man tried, for the child's sake. but i doubt he managed to make a completely aseptic transfer from the room she lived in to the spaceport on altaira. the authorities on altaira should have known it. they should have killed her and destroyed everything she'd touched. and _still_ the odds would have been bad!" jensen said, "but you can't do that, nordenfeld! not now!" "i shall take every measure that seems likely to be useful." then nordenfeld snapped, "damnation, man! do you realize that this chlorophage can wipe out the human race if it really gets loose? do you think i'll let sentiment keep me from doing what has to be done?" he flicked off the vision-phone. * * * * * the _star queen_ came out of overdrive. her skipper arranged it to be done at the time when the largest possible number of her passengers and crew would be asleep. those who were awake, of course, felt the peculiar inaudible sensation which one subjectively translated into sound. they felt the momentary giddiness which--having no natural parallel--feels like the sensation of treading on a stair-step that isn't there, combined with a twisting sensation so it is like a spiral fall. the passengers who were awake were mostly in the bars, and the bartenders explained that the ship had shifted overdrive generators and there was nothing to it. those who were asleep started awake, but there was nothing in their surroundings to cause alarm. some blinked in the darkness of their cabins and perhaps turned on the cabin lights, but everything seemed normal. they turned off the lights again. some babies cried and had to be soothed. but there was nothing except wakening to alarm anybody. babies went back to sleep and mothers returned to their beds and--such awakenings being customary--went back to sleep also. it was natural enough. there were vague and commonplace noises, together making an indefinite hum. fans circulated the ship's purified and reinvigorated air. service motors turned in remote parts of the hull. cooks and bakers moved about in the kitchens. nobody could tell by any physical sensation that the _star queen_ was not in overdrive, except in the control room. there the stars could be seen. they were unthinkably remote. the ship was light-years from any place where humans lived. she did not drive. her skipper had a family on cassim. he would not land a plague ship which might destroy them. the executive officer had a small son. if his return meant that small son's death as well as his own, he would not return. all through the ship, the officers who had to know the situation recognized that if chlorophage had gotten into the _star queen_, the ship must not land anywhere. nobody could survive. nobody must attempt it. so the huge liner hung in the emptiness between the stars, waiting until it could be known definitely that chlorophage was aboard or that with absolute certainty it was absent. the question was up to doctor nordenfeld. he had isolated himself with kathy in the ship's hospital compartment. since the ship was built it had been used once by a grown man who developed mumps, and once by an adolescent boy who developed a raging fever which antibiotics stopped. health measures for space travel were strict. the hospital compartment had only been used those two times. * * * * * on this voyage it had been used to contain an assortment of botanical specimens from a planet seventy light-years beyond regulus. they were on their way to the botanical research laboratory on cassim. as a routine precaution they'd been placed in the hospital, which could be fumigated when they were taken out. now the doctor had piled them in one side of the compartment, which he had divided in half with a transparent plastic sheet. he stayed in that side. kathy occupied the other. she had some flowering plants to look at and admire. they'd come from the air room and she was delighted with their coloring and beauty. but doctor nordenfeld had put them there as a continuing test for chlorophage. if kathy carried that murderous virus on her person, the flowering plants would die of it--probably even before she did. it was a scrupulously scientific test for the deadly stuff. completely sealed off except for a circulator to freshen the air she breathed, kathy was settled with toys and picture books. it was an improvised but well-designed germproof room. the air for kathy to breathe was sterilized before it reached her. the air she had breathed was sterilized as it left her plastic-sided residence. it should be the perfection of protection for the ship--if it was not already too late. the vision-phone buzzed. doctor nordenfeld stirred in his chair and flipped the switch. the _star queen's_ skipper looked at him out of the screen. "i've cut the overdrive," said the skipper. "the passengers haven't been told." "very sensible," said the doctor. "when will we know?" "that we can go on living? when the other possibility is exhausted." "then, how will we know?" asked skipper stonily. doctor nordenfeld ticked off the possibilities. he bent down a finger. "one, her father took great pains. maybe he did manage an aseptic transfer from a germ-free room to altaira. kathy may not have been exposed to the chlorophage. if she hasn't, no bleached spots will show up on the air-room foliage or among the flowering plants in the room with her. nobody in the crew or among the passengers will die." he bent down a second finger. "it is probably more likely that white spots will appear on the plants in the air room _and_ here, and people will start to die. that will mean kathy brought contagion here the instant she arrived, and almost certainly that altaira will become like kamerun--uninhabited. in such a case we are finished." * * * * * he bent down a third finger. "not so likely, but preferable, white spots may appear on the foliage inside the plastic with kathy, but not in the ship's air room. in that case she was exposed, but the virus was incubating when she came on board, and only developed and spread after she was isolated. possibly, in such a case, we can save the passengers and crew, but the ship will probably have to be melted down in space. it would be tricky, but it might be done." the skipper hesitated. "if that last happened, she--" "i will take whatever measures are necessary," said doctor nordenfeld. "to save your conscience, we won't discuss them. they should have been taken on altaira." he reached over and flipped off the phone. then he looked up and into the other part of the ship's hospital space. kathy came out from behind a screen, where she'd made ready for bed. she was beaming. she had a large picture book under one arm and a doll under the other. "it's all right for me to have these with me, isn't it, doctor nordenfeld?" she asked hopefully. "i didn't have any picture books but one, and it got worn out. and my doll--it was dreadful how shabby she was!" the doctor frowned. she smiled at him. he said, "after all, picture books are made to be looked at and dolls to be played with." she skipped to the tiny hospital bed on the far side of the presumably virusproof partition. she climbed into it and zestfully arranged the doll to share it. she placed the book within easy reach. she said, "i think my father would say you were very nice, doctor nordenfeld, to look after me so well." "no-o-o-o," said the doctor in a detached voice. "i'm just doing what anybody ought to do." she snuggled down under the covers. he looked at his watch and shrugged. it was very easy to confuse official night with official day, in space. everybody else was asleep. he'd been putting kathy through tests which began with measurements of pulse and respiration and temperature and went on from there. kathy managed them herself, under his direction. he settled down with one of the medical books he'd brought into the isolation section with him. its title was _decontamination of infectious material from different planets_. he read it grimly. * * * * * the time came when the _star queen_ should have come out of overdrive with the sun circe blazing fiercely nearby, and a green planet with ice caps to be approached on interplanetary drive. there should have been droning, comforting drive noises to assure the passengers--who naturally could not see beyond the ship's steel walls--that they were within a mere few million miles of a world where sunshine was normal, and skies were higher than ship's ceilings, and there were fascinating things to see and do. some of the passengers packed their luggage and put it outside their cabins to be picked up for landing. but no stewards came for it. presently there was an explanation. the ship had run under maximum speed and the planetfall would be delayed. the passengers were disappointed but not concerned. the luggage vanished into cabins again. the _star queen_ floated in space among a thousand thousand million stars. her astrogators had computed a course to the nearest star into which to drive the _star queen_, but it would not be used unless there was mutiny among the crew. it would be better to go in remote orbit around circe iii and give the news of chlorophage on altaira, if doctor nordenfeld reported it on the ship. time passed. one day. two. three. then jensen called the hospital compartment on vision-phone. his expression was dazed. nordenfeld saw the interior of the control room behind jensen. he said, "you're a passenger, jensen. how is it you're in the control room?" jensen moistened his lips. "the skipper thought i'd better not associate with the other passengers. i've stayed with the officers the past few days. we--the ones who know what's in prospect--we're keeping separate from the others so--nobody will let anything out by accident." "very wise. when the skipper comes back on duty, ask him to call me. i've something interesting to tell him." "he's--checking something now," said jensen. his voice was thin and reedy. "the--air officer reports there are white patches on the plants in the air room. they're growing. fast. he told me to tell you. he's--gone to make sure." "no need," said nordenfeld bitterly. he swung the vision-screen. it faced that part of the hospital space beyond the plastic sheeting. there were potted flowering plants there. they had pleased kathy. they shared her air. and there were white patches on their leaves. "i thought," said nordenfeld with an odd mirthless levity, "that the skipper'd be interested. it is of no importance whatever now, but i accomplished something remarkable. kathy's father didn't manage an aseptic transfer. she brought the chlorophage with her. but i confined it. the plants on the far side of that plastic sheet show the chlorophage patches plainly. i expect kathy to show signs of anemia shortly. i'd decided that drastic measures would have to be taken, and it looked like they might work, because i've confined the virus. it's there where kathy is, but it isn't where i am. all the botanical specimens on my side of the sheet are untouched. the phage hasn't hit them. it is remarkable. but it doesn't matter a damn if the air room's infected. and i was so proud!" jensen did not respond. * * * * * nordenfeld said ironically, "look what i accomplished! i protected the air plants on my side see? they're beautifully green! no sign of infection! it means that a man can work with chlorophage! a laboratory ship could land on kamerun and keep itself the equivalent of an aseptic-environment room while the damned chlorophage was investigated and ultimately whipped! and it doesn't matter!" jensen said numbly, "we can't ever make port. we ought--we ought to--" "we'll take the necessary measures," nordenfeld told him. "very quietly and very efficiently, with neither the crew nor the passengers knowing that altaira sent the chlorophage on board the _star queen_ in the hope of banishing it from there. the passengers won't know that their own officials shipped it off with them as they tried to run away.... and i was so proud that i'd improvised an aseptic room to keep kathy in! i sterilized the air that went in to her, and i sterilized--" then he stopped. he stopped quite short. he stared at the air unit, set up and with two pipes passing through the plastic partition which cut the hospital space in two. he turned utterly white. he went roughly to the air machine. he jerked back its cover. he put his hand inside. minutes later he faced back to the vision-screen from which jensen looked apathetically at him. "tell the skipper to call me," he said in a savage tone. "tell him to call me instantly he comes back! before he issues any orders at all!" he bent over the sterilizing equipment and very carefully began to disassemble it. he had it completely apart when kathy waked. she peered at him through the plastic separation sheet. "good morning, doctor nordenfeld," she said cheerfully. the doctor grunted. kathy smiled at him. she had gotten on very good terms with the doctor, since she'd been kept in the ship's hospital. she did not feel that she was isolated. in having the doctor where she could talk to him at any time, she had much more company than ever before. she had read her entire picture book to him and discussed her doll at length. she took it for granted that when he did not answer or frowned that he was simply busy. but he was company because she could see him. doctor nordenfeld put the air apparatus together with an extremely peculiar expression on his face. it had been built for kathy's special isolation by a ship's mechanic. it should sterilize the used air going into kathy's part of the compartment, and it should sterilize the used air pushed out by the supplied fresh air. the hospital itself was an independent sealed unit, with its own chemical air freshener, and it had been divided into two. the air freshener was where doctor nordenfeld could attend to it, and the sterilizer pump simply shared the freshening with kathy. but-but the pipe that pumped air to kathy was brown and discolored from having been used for sterilizing, and the pipe that brought air back was not. it was cold. it had never been heated. so doctor nordenfeld had been exposed to any contagion kathy could spread. he hadn't been protected at all. yet the potted plants on kathy's side of the barrier were marked with great white splotches which grew almost as one looked, while the botanical specimens in the doctor's part of the hospital--as much infected as kathy's could have been, by failure of the ship's mechanic to build the sterilizer to work two ways: the stacked plants, the alien plants, the strange plants from seventy light-years beyond regulus--they were vividly green. there was no trace of chlorophage on them. yet they had been as thoroughly exposed as doctor nordenfeld himself! the doctor's hands shook. his eyes burned. he took out a surgeon's scalpel and ripped the plastic partition from floor to ceiling. kathy watched interestedly. "why did you do that, doctor nordenfeld?" she asked. he said in an emotionless, unnatural voice, "i'm going to do something that it was very stupid of me not to do before. it should have been done when you were six years old, kathy. it should have been done on kamerun, and after that on altaira. now we're going to do it here. you can help me." * * * * * the _star queen_ had floated out of overdrive long enough to throw all distance computations off. but she swung about, and swam back, and presently she was not too far from the world where she was now many days overdue. lift-ships started up from the planet's surface. but the _star queen_ ordered them back. "get your spaceport health officer on the vision-phone," ordered the _star queen's_ skipper. "we've had chlorophage on board." there was panic. even at a distance of a hundred thousand miles, chlorophage could strike stark terror into anybody. but presently the image of the spaceport health officer appeared on the _star queen's_ screen. "we're not landing," said doctor nordenfeld. "there's almost certainly an outbreak of chlorophage on altaira, and we're going back to do something about it. it got on our ship with passengers from there. we've whipped it, but we may need some help." the image of the health officer aground was a mask of horror for seconds after nordenfeld's last statement. then his expression became incredulous, though still horrified. "we came on to here," said doctor nordenfeld, "to get you to send word by the first other ship to the patrol that a quarantine has to be set up on altaira, and we need to be inspected for recovery from chlorophage infection. and we need to pass on, officially, the discovery that whipped the contagion on this ship. we were carrying botanical specimens to cassim and we discovered that they were immune to chlorophage. that's absurd, of course. their green coloring is the same substance as in plants under sol-type suns anywhere. they couldn't be immune to chlorophage. so there had to be something else." "was--was there?" asked the health officer. "there was. those specimens came from somewhere beyond regulus. they carried, as normal symbiotes on their foliage, microörganisms unknown both on kamerun and altaira. the alien bugs are almost the size of virus particles, feed on virus particles, and are carried by contact, air, and so on, as readily as virus particles themselves. we discovered that those microörganisms devoured chlorophage. we washed them off the leaves of the plants, sprayed them in our air-room jungle, and they multiplied faster than the chlorophage. our whole air supply is now loaded with an airborne antichlorophage organism which has made our crew and passengers immune. we're heading back to altaira to turn loose our merry little bugs on that planet. it appears that they grow on certain vegetation, but they'll live anywhere there's phage to eat. we're keeping some chlorophage cultures alive so our microörganisms don't die out for lack of food!" the medical officer on the ground gasped. "keeping phage _alive_?" * * * * * "i hope you've recorded this," said nordenfeld. "it's rather important. this trick should have been tried on kamerun and altaira and everywhere else new diseases have turned up. when there's a bug on one planet that's deadly to us, there's bound to be a bug on some other planet that's deadly to it! the same goes for any pests or vermin--the principle of natural enemies. all we have to do is find the enemies!" there was more communication between the _star queen_ and the spaceport on circe iii, which the _star queen_ would not make other contact with on this trip, and presently the big liner headed back to altaira. it was necessary for official as well as humanitarian reasons. there would need to be a health examination of the _star queen_ to certify that it was safe for passengers to breathe her air and eat in her restaurants and swim in her swimming pools and occupy the six levels of passenger cabins she contained. this would have to be done by a patrol ship, which would turn up at altaira. the _star queen's_ skipper would be praised by his owners for not having driven the liner into a star, and the purser would be forgiven for the confusion in his records due to off-schedule operations of the big ship, and jensen would find in the ending of all terror of chlorophage an excellent reason to look for appreciation in the value of the investments he was checking up. and doctor nordenfeld.... he talked very gravely to kathy. "i'm afraid," he told her, "that your father isn't coming back. what would you like to do?" she smiled at him hopefully. "could i be your little girl?" she asked. doctor nordenfeld grunted. "hm ... i'll think about it." but he smiled at her. she grinned at him. and it was settled. one against the stars by vaseleos garson earth's last hope against the vicious radio-plague. a gleaming ship racing to bring salvation back from venus. and hidden on the ship a thirteenth man--a plague carrier whose touch brought screaming death. [transcriber's note: this etext was produced from planet stories summer 1944. extensive research did not uncover any evidence that the u.s. copyright on this publication was renewed.] this was it. its slim bright shape was earth's last hope. what matter the sweat, the blood and the tears that had gone into each rivet, every plate? what matter the eyes blurred and dulled with plans, blueprints? what matter the cost. this was it. it was done. they stood there--the riveters, the welders; the draughtsmen, the engineers; the mathematicians, the technicians--and there glowed in their eyes a living flame. this was the ship of hope. its rockets flickered into blue flames. their soft purr of power deepened. abruptly, the earth was trembling to the throaty roar of rockets. in its long steel-rollered cradle, the ship trembled. one of the workers, his denim trousers grease-stained, bending down, scooped up a handful of the dust at his feet, flung it at the shining ship. "just for luck," he said. in the glass bulge atop the shining ship, john bairn, the pilot, licked feverish lips. he brushed the black hair away from his gray eyes. his stubby fingers raced over the keys of the control panel before him. his right hand touched--almost reverently--the scarlet handle of the firing lever. he pushed the lever forward one notch ... two ... three.... he braced himself in the hydraulic-cushioned pilot's chair. "venus, here we come!" the rockets roared faintly even in this sound-proofed cubicle. then the pounding blood in his ears washed out all other sound. the pounding in his ears grew throatier, louder. the 9g acceleration blacked him out. that dive was a little too steep, he was thinking, first time i ever blacked out with somebody on my tail. he jerked his head around to see where the butcher was. and then he remembered. he looked ahead. the stars were steady white flames in the black pool of space. ah, there it was! the pale green flame that was venus. somewhere, there, lay earth's salvation. arlington arden, the metal expert, came into the cubicle then, his blond face pale. "some shove, huh?" he opined. bairn nodded, his gray eyes watched the orientation chart whose red and green and yellow lights were flickering in the rhythm that showed they were on the mathematically-charted course. "think the stuff is really there, arlie?" bairn questioned. "we're staking our lives on it, john." "yeah, and the lives of a billion like us. what if it isn't?" "venus' spectrum shows its presence. it's not an emanation that is easily duplicated. if it isn't, it's too much of a grim joke--because the money in this ship could have paid for a thousand experiments. my mary's got a touch of blue coloring in her skin--the first symptom, y'know." "sorry," bairn said, and his voice was soft. "beautiful," arden said. "i hope mary can see it sometime." he was looking out at space, his arms clasped behind him. "it's not like i thought, though--this being the first humans to see the stars away from earth." he stopped. "it's so damn big and beautiful it hurts," he said at last. "yeah, i know," bairn put in. "it makes guys like us feel cheap and small." "no!" the word was explosive. bairn jerked around in the pilot's cradle and stared. arden had a frown on his forehead. "and who in blue blazes are you?" bairn snapped. "joe," the big blocky youngster said, as if that explained everything. "joe, huh?" bairn grunted. "how did you get on this ship?" * * * * * joe's brown eyes stared steadily at bairn, and his big shoulders shrugged. "i stowed away." and then as the two stared blankly at him, he hurried on: "i had to. really. there's a legend in our family that a man named joe will be the first to reach the stars. it was promised way back when. so i had to come. i had to!" bairn grunted again. "isn't much we can do about it now, i guess. but you'll have to earn your way. what can you do?" joe grinned--a big grin that made bairn and arden smile. he shrugged and grinned again. "i don't know. but i'll be good for something. you'll see." "all right. arlie, will you take him down to the rocket room? maybe the gang can find something for him to do." "come on, joe," arden said. joe shook his head. "not just yet," he answered. "i'd like to tell you something first." he pointed out toward the stars. "a minute ago, you said"--he nodded at bairn--"this makes us feel cheap and small. "you're wrong. you're just afraid. all this is man's--yours, mine, ours. it's just so darn big, we don't realize it. but this is our destiny--that's what the prophet said a long time ago. it took a disease like that sweeping the earth now to get us here. but we're here. the stars are our destiny. no sense in being otherwise. no sense in feeling cheap and small." he stopped, looked at bairn and arden. "don't you feel it?" joe asked. "this first time the earth shackles are loosed? don't you feel the power and understanding and strength the stars give you out here? "this is where i belong," joe said. "out here where you can see what you're reaching for. that's why i had to come." he stopped and a slow embarrassed flush crept over his face. "see what i mean?" surprisingly, it was bairn who answered: "thanks, kid, you're good for something all right. i don't know what it is about you, but you give a guy a sense of--peace, i guess you'd say." "belonging?" arden put in. "that it, johnny?" "yeah, that's it," bairn said, and turned back to his orientation board. "so run along, kid." arlie arden, leading the way down the circular staircase that went to the power room, said abruptly: "you're no city man, are you, joe? i've never seen cloth like that made in the cities. that tunic you're wearing looks like it's made up for the north forests." "no," joe answered shortly, "i'm not a city man. i'm a wooder." they left the stairway, moved along a tube passage. "not a member of that crazy cult that wants a back-to-the-forests movement?" joe's denial was quick, and arden looked at him sharply. the stowaway was looking down at his toes as he walked on. arden shrugged. "here," arden said at last, stopping before a huge oval door that jutted from the tube. he twisted a wheel on the door, pushed the heavy portal open. arden watched the stowaway as he stepped into the power room. joe stopped and his brown eyes lifted first, then dropped down to rest on the huge generators that were making the air pulse with vibration. then his eyes moved to the huge dull-metal bulk that occupied the whole far end of the power room. his gaze took in the feeder pipe that evenly cleaved the huge bulk of the machine in half; the long neat rows of switches and valves that broke the austere front of the power plant. joe breathed deep once then turned questioningly to arden who was watching him. * * * * * "that's what drives the ship, joe," arden said. "reduced to its simple terms it's an atom smasher. hidden deep within that bulky outfit lies a block of uranium, constantly bombarded with electrons made a trifle heavier by running up against a magnetic current operating at right angles to them. the resultant disturbance of the uranium is harnessed and fed into the rocket tubes." arden glanced at joe whose eyes were fixed on the feeder pipe. "that's a funny thing, joe, that pipe you're looking at." "why?" "through that pipe comes water." "water?" arden nodded. "for some reason that not even the technicians who worked on that plant know, microscopic jets of water have to be hurled into the chamber with the bombarding particles to cause proper power." "water?" joe asked. "you drive this ship with water?" arden smiled. "yes, water and the help--not negligible either--of uranium. it'll take exactly two hundred and twelve gallons of water to drive to venus, and the same amount back--at least that's what black tom figures." arden nodded to the huge dark-skinned, black-haired man in white coveralls who stood by an instrument panel, checking figures off on a clip board he held. "come on, joe," arden said, heading for a ladder that was bolted to the wall at one side of the huge power room. joe followed up the ladder, was on the heels of arden as the metal expert crawled through a cubbyhole at the top. "see?" arden said straightening up. "water." joe looked at the row of horizontal metal cylinders that stretched before him. the tops of them were a foot taller than his head, and he moved to the side, and counted aloud to eleven before arden said: "we might starve and go naked, but we'll never run out of catalyst or get thirsty," arden opined. "each of those tanks holds six hundred gallons and there're twenty-four of them." joe moved to the nearest of the tanks, rubbed his hands on the moist surfacing and commented absently: "it feels like velvet." arden laughed a little. "come on, joe, i'll turn you over to black tom and he'll put you to work doing something. he never likes to see anyone idle." they crawled out of the wall cubby and down the ladder. a second white-garbed man had joined the power room head and they were talking together as arden and joe approached. "that's whitey burnet," arden said, and started, for joe had halted dead in his tracks. black tom morrissey and burnet turned then. morrissey said, "hello, arlie," briefly and turned back to his gauge panel. burnet stood rigid for a moment at the sight of joe. then with three quick strides burnet was at joe. he said softly: "damn you, joe." and lashed out with a hard fist. the blow caught joe on the cheek, cutting the skin, and staggering him momentarily. joe started to swing his browned fist up, then slowly he lowered it. he looked at burnet with quiet brown eyes. "i can't hit you, paul. you know that." paul's face was white. "no," he said, and he was almost bitter. "i know that." then he turned his back on joe and walked away. arden's blue eyes watched the by-play, observed: "whitey doesn't like you very much, huh?" joe's brown eyes were dull looking as he pulled his gaze from burnet's retreating back and looked at arden. "no," he said, and his voice was flat. "paul doesn't like me much." with an effort he smiled, added: "shall we find out what i can do?" arden nodded.... joe wilding met the rest of the crew at the arbitrary meal that was termed supper. * * * * * joe came in behind arden, and unobtrusively slid to one side of the door, and watched the men around the table laughing and joking. arden said: "fellas, i'd like you to meet a new crew member." the laughing and joking stopped, and the eyes of eleven men measured joe wilding. black tom winked at joe and went back to his eating. whitey burnet, after a brief angry glance, turned back to his plate. arden added: "his name is joe wilding." the others at the table smiled, nodded or spoke according to their habits--except one, a nervous redhead, who stared at joe. then he looked around at the others at the table. he was a little apologetic. the redhead said: "i know this guy. i piloted the ship that took him to the rock for sedition. i don't think we want him on the ship. he's one of those wild ones who tried to kidnap the president." arden grunted: "i thought so." burnet, his normally ruddy face white, reared to his feet: "no!" he shouted. "you're wrong, herd. he was pardoned. i know. they found he had nothing to do with the kidnaping." "maybe so," charlie herd, assistant pilot said, still apologetically. "but i know i took him to the rock--and i didn't hear anything after that about him. but he's the same guy. "he was a wild one," herd said almost dreamily. "he knocked out two of the guards, grabbed one of the chutes and was almost out of the ship before i rolled the crate over and bashed him against the cabin wall." whitey burnet's face was still white. "look," he said. "i don't like joe, but it's something personal. the tribunal found him innocent, so why not give him a chance?" arden turned to joe who still stood by the side of the door, his handsome bronzed face stiff. "well?" arden asked. joe smiled. he said, looking at the red-headed herd: "you're right as far as you went. i was taken to the rock. i did try to break loose. the tribunal found me not guilty and apologized. i was released. and here i am." herd looked back at joe, and then he smiled, half-apologetically: "i'll take you at face value. you look all right." "thanks," joe said. bob and ronnie guetschow, the bulky professor twins, broke the ensuing silence with: "come on and eat." the ice broke silently. arden motioned joe toward an empty chair at the table. joe moved forward, then stopped as his eyes counted the men at the table. "sit down, joe," arden grunted, picking himself a convenient, padded chair. surprisingly, joe shook his head. "no," he said, and for the first time he looked embarrassed. there was a slight flush under his tan. the table talk stopped again. george keating, the thin, wiry electrical engineer, said half-jokingly: "afraid you'll get contaminated?" joe's tan skin lost its red of embarrassment, twisted strangely. "sorry," put in keating hastily. "only joking." joe swallowed. then: "i'm just superstitious, i guess." the words rushed out. "if i sit down, that'll make thirteen." * * * * * ed parman, black-haired assistant to black tom, jumped hastily to his feet. "good gravy, he's right. you sit down, joe, i'll finish my pudding in the corner." joe said: "sit down. i'm used to discomfort. i'm a wooder." he grinned. parman grinned back, started in on his pudding. joe, the men were to notice in the coming days, seemed to make a point of never eating with the bunch after that. but he did it so smoothly, it wasn't offensive.... venus, in the days that followed, grew from a tiny yellow-green flame, that bairn, the pilot, had noticed in the first hours of the flight, to a white globe, just hinting a tint of blue, that began to fill the heavens before him. joe, on an off hour from the power room, sat quietly in the co-pilot's chair, drinking in the planet. he and bairn, usually so taciturn, had talked much in the days of the flight. this day, when joe came in, bairn looked at him with a strange twist to his mouth. he said nothing for quite a while, the two just sitting there, joe looking up and ahead, bairn, apparently preoccupied with figures on his charts. finally bairn said: "has arden said anything to you?" joe shook his head. "no," he said. "why?" bairn, apparently speaking absentmindedly, said: "arlie's wife, mary, has the radio disease. she's in the first stage. has the blue coloring. it means everything to arlie that this ship gets to venus and back. venus has the only radio-active static compound that matches the stuff from the meteorite." "yes," joe said. "i know. it was only luck that scientist, struthers, had that meteorite in the room with him when he had the disease. it cured him. and then scientists and astronomers searched star spectrums to find a match for the color scheme that they found in the meteorite metal." "this ship," bairn put in, "cost billions; it meant the first real cooperative program the world's nations ever had. it would be ghastly if one man caused the destruction of earth's last hope from doom. wouldn't it, joe?" joe's face was grim as he nodded. "how would you feel if you were to blame for drowning out humanity, joe?" joe stood up, and his body was shaking. "tell me, joe," bairn said quietly. "why have you kept yourself from eating with the rest of the guys? why is it when you come here you're always smelling of antiseptic?" there were tears in joe's brown eyes when he faced bairn. "okay, john, what shall i do?" "there's not much harm done yet? arlie says that in the first stages, it's only communicable by contact. but once it gets past that first stage, it goes hog wild. "tell me, joe, when did the nauseous attacks first come?" joe's brown eyes were dead. "two days before the ship left." "you were willing to sacrifice mankind just to see the stars yourself, joe?" it was arlie arden who came in quietly, then. "no," said joe, and then he looked at the two of them. "believe me," he said, and his voice was deep, vibrant. "i was drawn to the ship by a power greater than any of us. i knew the terrible gamble. for if this ship crashes before it gets back to earth with that venus ore, it means the end of man. "i knew that. everything my mind said pointed out the consequences. my mind said no in every possible way. but ... my mind had no chance against the impulse that drove me aboard ship. "somehow i know that my presence on board this ship means the salvation of mankind...." he shook his head at arden whose lips were pursed to speak. "it's not egotism or some crack-brained idea. i couldn't rest until i was aboard ship. i'm chosen to do something to preserve mankind, not destroy it. it's just as if something bigger than me or you or the universe had taken hold of me, placed me here." arden said: "do you know what we're going to do to you, joe?" joe looked at him steadily as arden drew a gun from his pocket. "we're going to kill you and throw you out in space. it's the only way to keep you from contaminating the rest of us." joe said: "you can't." simply, he said it. bairn said quietly. "we will, joe." arden lipped: "do you think we can value one life against earth's billions? this is the ship of hope, joe. this is earth's last chance. if we fail, it's the end. for once the disease starts, there is no stopping it." he leveled the automatic "good-bye, joe." * * * * * joe's body slumped, almost in weakness. then he galvanized into a human whirlwind. the gun cracked but joe was not there. he'd spun quickly, diving for the cubicle door, flinging a chart as he fled. the flying chart disturbed arden's aim. the gun blasted, and joe felt the wind of the bullet fanning his cheek. then joe was in the sloping passageway, sliding down the ramp. he heard the crack and the banshee wail as another bullet struck the duralloy wall and ricocheted. he hurled his body toward the branch passage that led toward the power room, and then a communications speaker ahead of him cried out, bringing arden's voice from the pilot's cubicle: "kill joe wilding--but for your life don't touch him!" joe stopped running abruptly then. he was trapped, for that communications system had outlets all over the ship, and it wouldn't do to advertise his presence by running. only the stealth he'd learned in his years of wooding could help him now. but what good was all his wood training in this huge hulk of shining metal? no chance for camouflage, no chance to dive into a creek and swim away so that your spoor could be lost in the swirling water. and then joe smiled and began to run softly. he had a place to hide if he could make it. the quick pat of hurrying steps stopped him short and his quick mind hurled his body to the side of the passage and asprawl on the floor where the lights cast a shadow. it was paul burnet hurrying up the passage, the light glinting on the butt of the automatic belted at his waist. only for an instant did burnet hesitate, then he ran on. his voice drifted back softly: "i'm giving _you_ another chance. we're even now, joe." joe rose to his feet and hurried on to the power room. joe halted, breathing deeply. black tom would be too interested in his charts to hear what little sound he might make. at the huge oval door leading into the power room, joe halted, breathing deeply. then, quietly, easily, he swung open the heavy door, stepped inside, his eyes searching for black tom. softly, he pulled the portal closed, stood there breathing in long, quiet breaths. then he moved across the huge power room, feet moving as cautiously as if he were stalking a deer in the autumn woods. black tom's head was bent over a report sheet, his fingers were busy with a pencil. he shook his head, and joe was motionless. then a chuckle came from black tom's lips, and under cover of the sound, joe made for the ladder leading to the water compartment. black tom's head lifted as if startled; his head began to turn toward the exit door. joe went up the ladder like a frightened monkey, fairly blasted himself through the cubbyhole at the top and then rolled quietly inside. he lay there, his heart pounding with the quick exertion as he heard black tom's footsteps moving across the floor. he held his breath; black tom's grunt of puzzlement came muted to his ears. the footsteps returned to the chart table, and joe risked a look to see black tom's head once more bent in study. joe lifted himself to his feet, went over and touched the wet surface of the first of the water cylinders reverently. he walked on down the line, patting each of the huge tanks till he had reached the last. his arms reached up, his hands gripped the top of the cylinder and the sinewy muscles in his back and arms lifted himself to the top of it. then he slid down from the top into the wedge shaped space between the circumference of the tank and the bulwark of the wall. this was sanctuary, joe thought. like a cave in the forest when the wolf-pack keened out their howls for your blood. only different. for it was your friends who wanted to kill you. in the darkness, joe's teeth gleamed in a quick smile. then joe fell asleep. * * * * * arden was weary when he met john bairn coming down from his time of duty in the pilot cubicle. "he's gone," arden said. "just as if he had stepped out into space. now we're worse off than ever." bairn nodded, said: "i get it. if he's on this ship, he'll have to come in for food; we won't know what he's touched. maybe one of the more susceptible among us with a scratch may touch something he had and won't know. the infected one will pass like the touch of death among us." arden said: "everything we know he might have touched has been destroyed or disinfected, but there may have been something we missed. damn him!" arden's voice was flat, hopeless. "it's hard to imagine joe as the destroyer he is. i talked to him by the hour. i liked him; and even now, when i know what a potential of death he is--that's what makes me so damn mad." "tomorrow," arden said abruptly. "tomorrow we'll know if this cruise is in vain." bairn amended it: "tomorrow, we land on venus; if the stuff's there, okay. if it isn't, we won't have to worry about joe wilding any more." * * * * * joe didn't know what time it was when it happened. but he knew the first leg of the journey was over. that steady thrumming of the motors that had worked its way into his body so that it had become a part of him drew away gradually and left a sense of emptiness behind. joe climbed down from his hiding place, flexed his cramped muscles and stood erect. he faced the wall, the blank duralloy steel wall and stared as if his eyes could pierce the opaqueness and look out upon venus. he stood there a long time, his hands clenched into hard fists at his side, bright-eyed and staring. "god!" he whispered. how did it look out there on venus--on that planet when this first earth ship landed? was it like earth--friendly, familiar? or inimical, alien? if he came out now, he could see it with his own wondering eyes--and die. if he stayed here, he might never see it. but his mission was not fulfilled. somehow, quite clearly, he realized that. so joe crawled back into his metal cave, into the darkness. the only sound in the quiet water compartment was a muffled sobbing. * * * * * arden it was who closed the heavy door to the chamber. "that's it," he said, and his voice was a caress. "there's enough of it in that lead-lined vault to rid the world. it's up to you, john, to take us safely home." some one of the men said: "how about wilding?" a hush came to the room, a silence tight and somehow menacing. arden's voice was harsh: "he can't hurt us now. we have the metal to cure us if he should contaminate us." whitey burnet said: "why not cure him?" "no," said arden. "i have the key to the vault. if one of us is infected, i'll open it and treat him. but joe wilding deserves to die. it wasn't his fault that we are still uninfected. he was willing to destroy the earth in order to be here. that threat is gone now, but he must suffer." "arlie," bairn said softly. "would mary want you to let joe wilding die?" arden spoke coldly: "did wilding care about mary when he stowed away on this ship?" bairn had no answer. * * * * * joe wilding was restless. even the fiery fever that racked him could not quiet him. he paced the long water compartment, legs weary but restless. he couldn't stand it here much longer; he had to get out into the light, out where he could move and see and feel something besides the dampness dripping upon him, the quick mutter of the pumps as they drove the catalyst to the firing chambers. he walked to the cubbyhole, looked down into the power room. whitey burnet was there, alone. impulsively, joe wilding climbed out of the cubbyhole and down the ladder. "paul," he said softly. "i'm hungry." paul burnet turned slowly. "hello, joe." they stood there, the two of them. whitey burnet, immaculate in his white work clothes; joe wilding, a heavy growth of beard on his face, his tunic dirtied, his hair mussed. "i gave you your chance, joe. just as you gave me mine. we're even." burnet turned to the communications phone, then turned back suddenly. "now you know, joe. now you know how i felt. you know how it is to be hunted, to be afraid of your own shadow, to know what a despicable creature you are. to be followed by a fear that freezes your guts--" "but i'm not afraid, paul. i'm just hungry, and tired of being alone." "i was alone, joe." "no, paul, you weren't alone, ever. carol's thoughts were ever of you. i hunted you the world over; but you always ran away. you never would give me a chance. and carol's letters always came back marked: 'no such person at this address'." paul's voice was almost mocking: "even now you act the gentleman, pretending. i hate your guts, joe wilding. but for you, carol and i would have been married long ago. i liked you once, joe wilding, i even thought what a wonderful brother-in-law you'd make. even now, i find myself liking you a little bit--but god knows i don't know why." "you'd better call them, whitey," joe said. "no, not yet. you saved my life when you dragged me away that day my kidnap plan failed. you carried me, fractured skull and all, away from the greatest chance a man ever had to make this a real world. if we had got the president we could have forced the wildwood doctrine down the people's throats." joe shook his head. "the people won't take forced medicine. they must have sugar-coated pills to cure them and lead them right." whitey cut in: "then you made me promise i'd quit. and you told carol of my plot, and she wouldn't look me in the face when i came." "she cried her eyes out when you left. she asked me to find you and bring you back. but you wouldn't listen." then, softly, "she's still waiting, paul. waiting for you." paul stood tensely, his eyes searching joe's bearded face. the atomic motor thrummed quietly. "you'd better call them, paul." whitey jumped unexpectedly, as the shrill keening of the danger siren suddenly keened into the power room. bairn's voice cracked through the speaker: "grab something, guys. a meteor, and we can't dodge!" like an exclamation point to his words came the heeling crash. * * * * * joe and paul were flung to the floor as the ship rocked and heaved. the lights went out, the motors suddenly cut off. there was a shuddering scream as metal tore; the air turned hot and dry. [illustration: _hell burst in the engine room._] the ship kept rocking as if caught in a great stormy sea. rolling on the floor, joe heard a deep roar that was beginning to grow shrill. a warning bell was ringing in his head; then he realized it was the bell signaling escaping air. then he was on his feet, holding himself against the heeling motion of the ship, crying out: "paul, where are you? paul, paul, paul...." "here," whitey's voice was weak, but joe followed it. he found paul, heaved him to his shoulders and staggered away toward a wall. it was the wall to the passageway he decided dully and felt along it until he found the door. it opened easily as if pushed by a giant hand. he struggled hard to get across the threshold against the pushing air. he made it, dropped paul to the passageway. then he tugged desperately against the pull of the air against the door as he dragged it shut. somehow, he got it closed, twisted the locking lever. he sat down against the wall of the passage and breathed in long, shallow breaths. in the darkness, he heard paul's voice: "did you mean that about carol," paul asked, and his heart was in it. "yes," said joe. "she's still waiting for you to come back to her." it was quiet there for a moment, with only the muted ringing of the bell from the power room seeping through the wall. joe said: "did i hurt you when i dropped you, paul?" "not much," burnet answered. "my head's a little dizzy, but it takes more than an easy jar like that to make it dangerous. forget it." "but how did you get through the physical for the trip? the metal plate in your skull should have barred you." "i'm one of the few who know what the power plant here is like, remember? besides, the physical wasn't too steep. and joe, i'm sorry i was such a heel to sock you when you couldn't hit me back. you'd have killed with the blow." "i know," said joe. he heard paul breathing in harsh gasps. "paul," he said anxiously. "it's all right." "but it isn't! here, i'll carry you to the first aid room." joe got up, lifted paul to his shoulders. joe had carried paul perhaps a hundred feet when lights flickering on the walls and the sound of footsteps signaled the advance of the others. "so," came arden's voice as the beam from a flashlight centered on joe's face, "the rat came out of his hole." after the blackness, the light hurt joe's eyes and he lowered his head. arden came forward quickly, slapped joe openhanded across the mouth. "i've waited a long time for this!" he slapped him again, and joe felt the blood trickling from his lips. joe lowered paul burnet easily to the floor. he wiped his lips with the back of his hand, said: "you don't understand. i'm bringing paul, he's hurt. his skull was fractured a long time ago, and it's reacting." he knelt beside burnet, took the hurt man's wrist. "how are you now, paul?" burnet smiled weakly: "a little better." arden kicked joe aside: "keep your diseased hands off him, traitor." joe got wearily to his feet. "arden," he said, "bairn told me how upset you are about your wife. that's why i excused those slaps. but this--" joe's right arm drew back swiftly, drove his doubled fist to arden's jaw. arden dropped as if the floor had fallen from under him. "that tears it, joe," bairn said. "i'm sorry, joe. but we have no recourse but to lock you up. you're a walking plague, and socking arden was the last straw." from the floor, burnet said weakly: "but arden had it coming...." "we can't be the judge of that. joe is worth no consideration now. don, lock joe up in one of the empty storage rooms, but don't get near him." "right," said timnson, the mathematician. "come on, wilding." joe started to move away, stopped and said: "see that one of the twins looks after paul, will you?" "go on," said bairn. joe went ahead of timnson. * * * * * the heavy door clanged shut behind joe, and he was alone in the darkness. the motors were still silent, and he wondered how much damage the meteorite had done to the ship. he felt his way to the communications phone, unhooked it. but the steady hum that signified that it was alive was absent. even the call speaker gave no sound. wearied, joe sat down against the wall, and despite the hunger feeling throbbing in his stomach fell asleep. it was the overhead light shining into his eyes that awakened him. his ears sought for the sound of the motors, no familiar thrum. the wandering meteor must have done quite a bit of damage. the communications phone buzzed. joe answered. "hello, joe," it was burnet's voice. "how are you, paul? the dizziness gone?" "right, but i guess it doesn't do any good. we're not going anywhere." burnet's voice was a little strained. "why?" put in joe. "that damn meteor knocked hell out of the rear blasting tubes, and some of the fellows are outside trying to replace the busted ones. but even if they get it fixed we're still derelict. that meteor took all of our water, and i guess you know what that means." joe was silent. then: "no catalyst, no move, is that it, paul?" "uh huh," paul answered, "no h-2-o, no go." "the cans," joe said, abruptly. "cans?" paul questioned over the wire. "cans?" "sure," said joe, and he was breathless as he hurried on. "paul, all that canned food. there's water in them. and there must be some water left in the pipes to the kitchen and the lav? have they thought of that?" "yes," said paul. "the pipes, i mean, not the cans. arden and bairn are having the pipes pumped out now, doc guetschow tells me. but i'll pass along the can suggestion." "was it really bad?" joe asked. "sure, they got the power room sealed again. but that water compartment was mashed to junk, and the water just went pftt! it's a good thing you got out there when you did, or you'd have been pftt! too. i'll ring you back with any later developments." joe pronged the receiver. he began to pace the room. he couldn't stay in here. there must be something he could do out there. but this room was better than any prison. his eyes searched the room. joe's eyes were sparkling all of a sudden. bless the planners who laid out this ship! he broke the heavy crowbar from the emergency wall chest. he twisted the heavy steel in the locking mechanism on the inner panel of the door. bracing his feet against the door and drawing the heavy bar toward him, he strained desperately. he knew from his meandering around the ship that the locking device was only to insure the doors would not open accidentally. the muscles in his back and shoulders bulged so that the tunic he wore split down the back. he tugged until his muscles quivered with the strain. he should break loose now so he could open the door from the inside. but nothing happened. * * * * * joe relaxed, stood back and wiped the sweat from his brow; the lack of food had weakened him. the locking mechanism should have given way. once more he inserted the bar in the device. once more he called on his wood-trained muscles. he tried desperately this time, exerting all the strength he could summon. blackness threatened to engulf. then as if in a dream, he heard the muffled cling! that meant the device had snapped. he fell to the floor, his breath coming in sobs. then he quieted, lifted his body up, and twisted the wheel. it turned easily, and the door pulled open at his tug. he came out into the passageway to face arden, gun drawn. arden cursed softly: "won't you stay put, joe?" joe shrugged. "you need me," he said. "need you?" repeated arden. "need you to infect us so we can't get the ship going again." joe watched arden, then he said: "arden, why not cure me; then i won't be dangerous and i can help?" "no." arden's voice was flat. "i'm the only man on ship who knows how to give the treatment, and you're not getting any. your life is forfeit for what you almost managed to do." "you won't stop me, now, arden," joe said. "you can barely see me now, and you're trying so hard to keep from vomiting out your guts. you've got the radio disease; why don't you cure yourself?" joe moved back slowly; arden's gun followed him hesitantly. "you," arden said. "you did it. you gave it to me." the gun steadied. "no," joe said. "you had it before i ever came aboard ship. but you didn't know it, did you, arden? you're a carrier, and you came to the ship straight from your wife." arden shook his head weakly. "i took the usual tests; it showed me free of it." "but you know the usual tests, arden; you know you can't tell for sure until you get the nausea. and it acts at varying speeds with different people, doesn't it?" arden's fingers whitened on the gun; and joe leapt aside suddenly. the shot blasted out. then the gun dropped from arden's fingers and he fell forward on his face, retching. joe lifted the fallen metal expert almost tenderly, and carried him toward the hospital room. when he brought his burden in, joe saw burnet sitting on the edge of the bed, slipping on his sandals. doc guetschow, one of the professor twins, was remonstrating with him, trying to keep him in bed. burnet shook himself free and stood up. then he saw joe placing arden's body on the bed. "well!" joe turned and smiled. then he was serious: "arden's got the radio disease." "your fault, joe," burnet said. "he was right." "no," joe said doggedly. "he had it when he came aboard, too. he's got it bad, too. see what you can do for him, doc." then joe trotted out of the hospital room, and headed for the kitchen storerooms. wick wilson, who doubled as cook and metallurgist, was opening cans and draining off the liquid into a tub. "help?" asked joe. wick wilson looked at joe briefly, said: "i thought you were in the brig." then, "sure, lug the tub down to the power room. we're trying to get enough water out of the juice to make catalyst." joe hoisted the tub to one shoulder. "how about something to eat?" wick went into the kitchen, pulled a half chicken out of the refrigerator, brought back. "southern fried," he said. "it'll hold you together." joe bit off a chunk and carried the rest in one hand as he balanced the tub of fruit and vegetable juices on one shoulder and strode from the room. * * * * * black tom was putting the finishing touches on a metal cylinder he had salvaged from some of the shattered tanks. as joe came in the power room door, black tom asked: "how does it look? been a long time since i did any welding, but it'll hold water." black tom and herd, the assistant pilot, had bolted the jury rigged tank to the floor, and had, through some amateur plumbing work, hooked up a pipe system to the atomic motor. joe jerked his chicken-filled hand at the tub on his shoulder. "where does this juice go?" morrissey apparently had just realized that joe was free. he looked at him blankly for a moment. "dump it in the tank," he said, pointing to the metal ladder leaning against the tank. "but keep your distance," he added. "we don't want to catch the plague." joe grinned, stuffed the remainder of the chicken in his mouth, carried the tub up the ladder, and dumped the conglomerated juices into the circular opening at the top of the tank. joe came down the ladder. "got enough yet?" he questioned. "hell, no," exploded black tom. "look at the gauge we rigged up. here." joe looked at the gauge affixed to the side of the tank. it was about two inches below a chalk line black tom had drawn. "the white line marks the absolute minimum of water we need to get the ship within gravitational pull of the earth; from there in it's up to our extensor vanes." "how much do you need yet?" joe asked. black tom grunted. "about twelve gallons--and if those juices run out, we'll have to do some wholesale lemon and orange squeezing." joe started to turn. black tom said: "thanks, joe, for the can suggestion. it may pull us through." joe nodded, went up with his tub for another load of juice. when he had dumped the second load in, he said: "wick's got whitey, ronnie guetschow and keating squeezing lemons. this is the last of the loose juice." he shook his head to clear his mind, said briefly, "excuse me," and hurriedly left the power room. when he came back, his face pale, his limbs shaking from the retching stomach, bairn and ed parman were talking to black tom. * * * * * bairn looked serious. "hell," he said. "it would boil down to that. the motor's okay, ed says. but i don't know where in blue blazes we're going to get enough water. timnson's got the hydraulic press from the workroom rigged up squeezing out the garbage we didn't dump." he turned to black tom: "you're sure your sand filter will take all the solids out, so it won't plug up the water jets?" black tom nodded. it was then bairn noticed joe. bairn said wearily: "haven't you caused enough grief, joe? arden's sick with the disease because of you. you've been a jinx ever since the trip started. why don't you crawl in a hole and die?" "i'm trying to help," joe said. "nuts," said bairn tiredly. then he turned to black tom. "we've got gasoline galore for operating the electrical units. think gas'll work?" "no," tom said briefly. joe's stomach was beginning to quiver again, and the figures of tom, bairn and parman were weaving. he could feel his pulses pounding raggedly, as if a million drummers were anxious to keep out of tempo. he forced himself to walk slowly from the room, but the dizziness caught him at the door and he had to hang on to the lever to keep from keeling over. his thoughts were kaleidoscoping, but one finally broke through clearly. it was the answer. he pulled himself erect, said through feverish lips: "bairn...." bairn said, without turning his head: "beat it, joe!" "please, john," joe said, "i know where to get more water." he staggered toward the three men, the floor rocking under him. he felt his mind shouting the words, but his desperate mind couldn't make his lips move. his eyes wouldn't focus; his legs wouldn't work. he only half-felt the hurt as his head struck the power room floor. "good," said bairn, almost pleased. "that's taking care of him. parman, shove him over in the corner. better put these rubber gloves on." it was a good three hours later when bairn and black tom stood at the gauge measuring the height of the water in the tank. "not good enough," black tom said. "if we don't crash on the moon, we'll end up as a satellite. that's all the water we can squeeze out of it." "damn," breathed bairn, "another gallon would take us home. but there isn't another lick of water on the ship." he checked off on his fingers: "the lav, the connecting pipes, the canned food, the garbage, the storage batteries, that does it, guys, i guess." the others stood quietly. bairn went on: "we might as well get going. maybe, the fruit juice has got more umph to it than the water, and we might coast in. but black tom says we've got enough to reach the moon's orbit track, but not enough to reach the gravity pull of the earth. "we've done all we can," he said. "now it's up to whatever providence watches over people like us." he licked dry lips and smiled. * * * * * the muted thrumming of the atomic motor gradually worked its way into joe's consciousness. he moved wearily, and then his mind, short-circuited by the ravages of the fever, cleared itself and he became aware of his surroundings. how long he'd lain there, joe couldn't tell as he staggered to his feet and toward the door. he had the answer, if he could make bairn listen. his glazed eyes stared around the power room. there was no one there. he weaved toward the water gauge, stared at it for a long time before it registered. why, his mind said dully, the tank's almost empty. joe staggered for the door. the door was a ton weight that fought against him to open it. when it finally opened, he left it that way. he got outside in the passageway, and his stomach rebelled. he was very sick for many moments. he crawled and staggered up the circular stairway toward the pilot's cubicle. his body was bruised and hurting from the many times his weak legs had betrayed him before he reached the door to the cubicle. he couldn't move the lever to the door. he tried to shout, but his voice was hoarse, weak. he pounded with both hands against the thick metal. but there was no answer. once again, he was sick. then wearily he retraced his footsteps, pounded lengthily on each door with his weakened muscles. they couldn't hear him, a bitter voice nagged at him. he had the answer, and they wouldn't listen. he didn't feel the pain as he rolled down the circular steps and lay at the bottom in a heap. somehow he moved on, crawling. if they couldn't listen, he'd have to do it. he reached the door to the power room, lifted his body across the threshold, and then weakness held him motionless. was this it, his heart questioned. this was what he had to do before the radio disease got him, wasn't it. he couldn't see, he couldn't hear, he couldn't feel. oh, god, he couldn't even think. was this it? his heart asked again. whatever the answer, it was somehow adequate ... for joe's body, weakened by the life-sucking plague moved slowly ... so very slowly.... * * * * * "we've nearly reached the last of the catalyst, if black tom's figures are right," bairn said to the men crowded into the pilot's cubby. "there's earth," parman said, and his voice was a caress. the whole crew was there in the cubby, save for arden and burnet and the medical guetschow twin. doc guetschow was down in sick bay with the other two, burnet's head having started to act up again after three days without water. "tom, you're sure your figures are right?" the other guetschow twin asked. "much as i hate to say it, yes. only a few hundred miles and we're finished." tom licked his puffed lips. it was quiet there in the cubby as the atomic motor drove the ship at tremendous speed through the void. "can't we coast in?" parman asked. "we've got tremendous acceleration." "but not enough," bairn said, "with the moon's gravitation field to reckon with." all their hearts must have stopped then, when the steady thrum became a staccato beat. "this is it," bairn said. the staccato turned to a broken rhythm, hesitated, and finally halted. "god," said herd, the co-pilot apologetically, "if the moon weren't around to hold us back." but it was there, looming huge and ugly off the starboard side. parman said: "i can feel it pulling." the strain made two or three of them giggle. bairn said as if to a naughty child: "it isn't that strong, ed." bairn's hand moved to click off the firing lever when the motors suddenly broke into thrumming life. the inertia of new flight came to the ship again. * * * * * they made a frozen tableau, those men standing in the pilot's cubby. ed parman was the first to break the tableau. he slumped to the floor, and lay there, his shoulders shaking convulsively. "herd," bairn said suddenly, "take over. come on, tom. whatever did this is in the power room." "joe?" herd asked. "i don't know." the two of them fled, leaving behind them, parman on his knees staring at the void, the others half-crying, half-laughing. bairn and black tom morrissey came into the power room. they stood awed at what they saw. joe was there. bairn said finally, voice as soft as the night wind over earth: "joe was right. he was good for something after all." tenderly, he and black tom lifted joe's dead body down from the tank, laid him gently on the floor. "the only thing we forgot, tom," bairn said. "_blood._" crimson still oozed slowly from joe wilding's cut wrists. there was a smile on his dead lips. for it was a man named joe who was the first to reach the stars--and the roaring rockets had scattered his eternal life across the star trails. mate in two moves by winston marks illustrated by ashman [transcriber note: this etext was produced from galaxy science fiction may 1954. extensive research did not uncover any evidence that the u.s. copyright on this publication was renewed.] [illustration] [sidenote: _murt's virus was catastrophically lethal, but it killed in a way no disease had ever thought of--it loved its victims to death!_] love came somewhat late to dr. sylvester murt. in fact, it took the epidemic of 1961 to break down his resistance. a great many people fell in love that year--just about every other person you talked to--so no one thought much about dr. murt's particular distress, except a fellow victim who was directly involved in this case. high dawn hospital, where 38-year-old dr. murt was resident pathologist, was not the first medical institution to take note of the "plague." the symptoms first came to the attention of the general practitioners, then to the little clinics where the g. p.s sent their patients. but long before anything medical was done about it, the plague was sweeping north and south america and infiltrating every continent and island in the world. murt's assistant, dr. phyllis sutton, spotted the first irregularity in the _times_ one morning and mentioned it to him. they were having coffee in murt's private office-lab, after completing reports on two rush biopsies. she looked up from the editorial page and remarked, "you know, someone should do a research on the pathology of pantie raids." * * * * * murt spooned sugar into his mug of coffee and stared at her. in their six months' association, it was the first facetious remark she had made in his presence. to this moment, he had held an increasing regard for her quiet efficiency, sobriety, professional dignity and decorum. true, she wore her white coat more tightly belted than was necessary and, likewise, she refused to wear the very low hospital heels that thickened feminine ankles. but she wore a minimum of come-hither in both her cosmetic and personality makeup. this startling remark, then, was most unexpected. "pantie raids?" he inquired. "whatever would justify an inquiry into such a patently behavioristic problem?" "the epidemic nature and its increasing virulence," she replied soberly. "this spring, the thing has gotten out of hand, according to this editorial. a harmless tradition at a few of the more uninhibited campuses has turned into a national collegiate phenomenon. and now secondary effects are turning up. instructors say that intramural romance is turning the halls of ivy into amatory rendezvous." murt sipped his coffee and said, "be thankful you aren't a psychiatrist. bacterial mutations are enough of a problem, without pondering unpredictable emotional disturbances." his assistant pursued it further. "it says the classrooms are emptying into the marriage bureaus, and graduation exercises this year will be a mockery if something isn't done. what's more, statistics show a startling increase in marriages at the high school level." murt shrugged broad shoulders that were slightly bent from long hours over a microscope. "then be thankful you aren't an overworked obstetrician," he offered as an amendment. she glanced up from the paper, with annoyance showing in her dark, well-spaced eyes. "is it of no interest to you that several hundred thousand youngsters are leaving high school and college prematurely because they can't control their glands?" "be glad, then," murt said coldly, "that you aren't an endocrinologist--now drink your coffee. i hear the microtome working. we'll have some business in a minute." dr. phyllis sutton rustled the pages of the _times_ together, folded it up and threw it at the wastebasket with more vigor than was necessary. the subject was momentarily closed. * * * * * his staff position at high dawn paid less, but the life suited dr. murt better than the hectic, though lucrative, private practices of many of his colleagues. he arrived at the hospital early, seven o'clock each day, to be on hand for quick tissue examinations during the morning operations. by ten, the biopsies were usually out of the way, and he spent the rest of the morning and early afternoon checking material from the bacteriology section and studying post-operative dissections of tumorous tissues and organs removed in surgery. it was engrossing, important work, and it could be accomplished in a normal work-day, leaving the pathologist considerable leisure to study, read and relax. shortly after the pantie-raid conversation with phyllis sutton, he found the evening paper attracting more than his usual quick perusal. this emotional fuss in the young human animal was beginning to preoccupy the newspaper world. writers were raising their eyebrows and a new crop of metaphors at the statistics, which they described variously as alarming, encouraging, disheartening, provocative, distressing, romantic or revolting, depending upon the mood and point of view. as june, the traditional mating month, wore into july, national statistics were assembled to reveal that marriages were occurring at almost double the highest previous rate, that the trend was accelerating rather than diminishing. jewelers and wholesale diamond merchants chalked up fabulous increases in the sale of engagement and wedding settings. clergymen and qualified public officials were swamped with requests for religious and civil marriage ceremonies. parks, beaches and drive-in theaters were jammed with mooning and/or honeymooning couples, and amusement parks began expanding their over-patronized tunnel-of-love facilities. the boom in houses, furniture, appliances and tv was on, and last year's glut of consumer goods for the home was rapidly turning into a shortage. all was not good news, however. the divorce courts reported their calendars stacked months ahead of time, and an increasing number of lurid headlines were devoted to the love-triangular troubles of the rich, famous and notorious. love-nest exposés and bigamous marriages rocketed in number. the whole world, adolescent and adult, was falling in love, with the inevitable unrequited infatuations, the jealousies, infidelities and the bitter-sweetness of wholesale, illicit, impossible love situations in which vulnerable people found themselves increasing astronomically. writers of popular newspaper psychology columns attributed the rampaging emotional fire to everything from mass-hysteria, caused by sunspots, to the paternalism of a government that gave increased income-tax deductions to married people. * * * * * dr. murt's growing interest was not entirely academic. his bachelorhood was no accident of fate, but rather a carefully contrived independence, for which he paid the price of eternal vigilance. as the world supply of eligible bachelors diminished sharply, his wariness increased, and he became more and more curt with nurses and female technicians at the hospital. he revealed the depth of his leeriness one afternoon at the scrub-up sink, where he and his assistant were washing after a messy dissection. phyllis sutton remarked, "holly, down in personnel, showed me a tabulation she ran off for her own curiosity today, doctor. do you realize that in this whole hospital there are only _eight_ unmarried female employees?" murt threw water droplets from his bare arms and muttered, "yes, and every one of them's giving me the eye--to say nothing of half the married ones." his aide dried her long arms and slender hands and looked at him with a crooked smile. "not to underestimate your good looks, doctor, but i am one of the unmarried females. i trust i'm not giving you too much trouble?" he looked up, startled. "yes--no, _no_--of course not. i'm referring to the nurses and the technicians. what's got into them? the whole lot seems to be on the make!" phyllis combed out her short dark hair and looked at him in the mirror. "i assure you the males are just as bad. these interns and four of the male nurses give me a physical with their eyes every time i happen to meet them." "i suppose this ties in somehow with your pantie-raid theory." "well, what do _you_ think?" "i don't think. i just dodge. you'd do well to do the same," murt told her, putting on his jacket and adjusting his tie. she sat down in his oak swivel-chair and crossed her slender ankles. "are you aware of the problem they have downstairs in the out-patient clinic?" "hadn't heard," murt said. * * * * * she removed a file from her purse and touched up her short nails. "the outlying clinics are sending their overflow to us. they can't seem to diagnose the odd symptoms they're getting." "i had noticed the large number of negative test results coming out of the lab," murt acknowledged. "haven't followed any of them through, though." "i have," phyllis said with a little frown. "seems to be a psychosomatic nightmare down there." "what are the symptoms?" "mostly neurotic," she said. "listlessness, loss of appetite, palpitations, cold sweats and absent-mindedness." "why don't they go to the psychiatric clinics?" "overloaded. they're sending patients here." "what age groups?" "from puberty to senility. i'd like your permission to do a little special work on blood samples." "another theory?" he asked caustically. "yes. will you give me your permission to test it?" murt adjusted his panama straw in the mirror and noticed that the nostrils of his straight nose were flared for some reason. "your time is your own after three p. m. every day. if you want to take time out from your thesis research, that's your business." he crossed to the door and was opening it when he became aware that he had had no answer. he looked back at the profile of his assistant's body, which was now stretched out full length, suspended at three points--her higher-than-practical heels on the linoleum tile, her spine and curved hips using only an inch of the chair's edge, and her head tilted over the chair's back. she inhaled from a king-size filter-tip cigarette and blew a feather of smoke at the ceiling. "_yuh!_" she said finally. her flat abdomen jumped at the exhaled syllable, and so did her generous breasts under the soft emerald-green street dress. "good _night_!" murt closed the door behind him quickly and became aware of a sharp stab of what he defined as pure rut--the first he had suffered in fifteen years. ii he taxied downtown to the athletic club, where he maintained his three-room apartment. the 20-story building was a citadel of masculinity--no females allowed--and recently it was an especial relief to enter the lobby and leave behind the world of turbulently mixed sexes. the small but lush entry chamber had a deserted air about it this afternoon. at the room desk, crumbley, the clerk, handed him his key with a pallid hand and returned to sigh over a colored picture in _esquire_--it was the "fold-out" page, featuring a gorgeous blonde reclining at full length. crumbley's expression, however, was far from the loose-lipped, lecherous leer that he normally exposed to such art. his eyes had a thin glaze over them, he breathed shallowly and, if dr. murt had not known the little man's cynically promiscuous nature so well, he'd have sworn crumbley was in love. upstairs, murt donned rubber-soled gym shoes and sweat clothes and rode the elevator back down to the gymnasium. three times a week, he put his muscles through the whole routine-work on the bars, rings, the leather horse, the rope climb and a twenty-lap jog around the balcony racetrack. afterward, he showered, took a dip in the swimming pool and retired to the health service department for a rubdown and some sunlamp. throughout the whole routine, he encountered not a single other member. while charlie, the husky blond masseur, hammered and kneaded his muscles, murt reflected on the abating interest in athletics at the club. "are we losing members, charlie?" he asked. "you'd think so from how dead it is up here," charlie replied. "but crumbley says we aren't. the guys just aren't exercising. can't figure it, doc. even with the usual summer slump, it's never been this slow." when he had absorbed all the punishment he could stand, murt rolled off, went into the ultraviolet room, set an alarm clock and lay down by himself on one of the paper-covered tables. he adjusted the dark goggles and reflected thankfully that he didn't have to go to the beach for his sun and have sand kicked in his face by a procession of predatory females, ogling his long limbs and trying to attract his attention. the clean smell of ozone was pleasant, the warmth of the lamps relaxed him, and he dozed off. he dreamed that he heard someone else come in and lie down on the next table and, when he raised his head to see who it was, was amazed to discover his assistant, dr. phyllis sutton, stretched out like himself, wearing only shower-sandals and goggles. the alarm clock wakened him from the disturbing dream. he was sweating profusely and took another shower, using the cold water at full needle force to dispel his shock at his subconscious. * * * * * wrapping the robe around him, murt returned to his apartment to dress for dinner. as he snapped the paper laundry band off a clean shirt, he caught himself wondering how old phyllis sutton was. twenty-eight? thirty? she appeared younger, but she was in her last year of residence to gain her specialty of pathology. that meant over eleven years of school and practice. she was a lovely creature, but she was no child. he had half an impulse to phone her for dinner, then became lost in studying his own reaction to the thought. pulse over a hundred, respiration quickening, irregular. there was a tensing of the abdomen, a faint burning in the pit of his stomach. he remembered the urge at the office, the dream in the sunroom, the sudden sweat that had required five minutes under the cold needle shower. after so many years of deliberate, scholarly celibacy, what was happening to him? he stared at the phone. with six motions of one finger, he could dial phyllis sutton's face into view, and suddenly he yearned to do that very ridiculous thing. after staring at her, off and on, for the six months since she had transferred to high dawn to complete her residency, now he wanted to see her face outside of working hours for some inexplicable reason. call her up, date her, take her dancing, proposition her--get this silly feeling off your chest! suppose she was busy or refused to go out with him? suppose she already had a boy friend? this last thought deepened the burn in the pit of his stomach, and he finished dressing listlessly. to hell with it! this was poker night. if he did succeed in dating his assistant, they'd inevitably talk shop. that was why he enjoyed a night of cards with his six non-medical brother clubmen, once a week. it was refreshing to break away from the professional point of view. no, he wouldn't sacrifice that for any woman. * * * * * he ate alone, read the paper, joined the poker party at seven o'clock, played six hands of stud, cashed in his chips and returned to his room. in a mood of deep irritation, he found phyllis sutton's home phone number and rang it four times with no result. he thought to try the hospital. she answered from the lab extension on audio only, but her voice and its frankly curious tone sent vertically polarized chills through him. "i--i wanted to apologize for my rudeness this afternoon," he said with difficulty from a suddenly dry mouth. there was a brief silence. "have you been drinking, dr. murt?" he noticed that she did not call him sylvester. why was he so damned thirsty for some little sign of warmth and friendliness from her? he cleared his throat. "no, i'm serious. it occurred to me that your interest in the out-clinic problem was commendable, and that i was rather short in my remarks to you." "oh! i take it i have your permission to work my project in during the day, then?" "that's right, so long as it doesn't interfere with the routine." he sounded stuffy to himself, but he was entirely out of practice in speaking to please a female. "thanks," she said wryly, and the conversation ended. somehow, the brief talk with her restored his perspective. once again she was his assistant, and the significance of her as a woman faded. she was a dedicated physician like himself. in another few years, she would find a residency of her own. she had no more inclination to knock off and become a woman than he had to squander his time and energy on attaining the status of family man. * * * * * it was with mounting admiration that he followed her new project in examining blood samples. as they came up from the clinic, she sorted the specimen tubes at once, putting a tiny snip of yellow scotch tape under the label of each sample that belonged to a patient with the new undiagnosed disorder. then, after the requested hemoglobin, blood sugar and other standard tests had been run, she retrieved the samples from the technicians, grouped them in a special rack and devoted every spare minute to further examination. she centrifuged, precipitated, filtered and stained over and over, using every qualitative procedure in the book. murt signed her requisitions for exotic reagents and rare stains. he helped her balance out the large centrifuge to get the maximum r.p.m. from it. he let her use the most costly of the fine-porosity filters. he had little hope of success, but it was good practice for her. she was required to identify every organism she found, bone up on its known effects, then determine that it could not cause the symptoms reported. she did all this without impairing her usefulness to murt. when he needed her, she was at his side, dissecting, taking down notes, preparing delicate sections and checking slides before they came to him. in several weeks, she exhausted all known tests on the first samples. after lunch one day, she turned her palms up. "_nichts da!_" she said, pulling a mashed cigarette from the huge pocket of her white smock. he glanced at her and swiveled to stare out the window. it was part of his tight campaign to prevent a disastrous recurrence of the emotional tempest he had suffered the day she had begun this research. "it was a nice brush-up on your bacteriology," he said. "have you saved the filtrates?" "yes, of course. did i overlook anything?" "nothing that we could do here, but there's an electron microscope downtown at ebert industrial labs. how about photomicrography? could be a filtrable virus." he knew that she was aware of the possibility, and also that she was reluctant to ask him for additional funds to go into a virus hunt with the expensive piece of equipment. "wonderful!" she told him. "i did hate to ask you, but it would be a shame to waste all that immaculate filtrate." iii a week passed, during which a bulletin from the government health service announced official suspicion that the human race was suffering a mysterious, pandemic affliction which was as yet undiagnosed. although the symptoms, as reported by hundreds of clinics, were relatively mild, the effect on the nation's economy was growing serious. industry and business reported unprecedented absenteeism. factory supervisors and insurance companies were frantic over the upsurge in accidents. it was estimated that almost fifty per cent of the population exhibited the symptoms of depression, absent-mindedness, insomnia and loss of appetite. negligent driving was increasing the highway toll sharply. educational institutions reported classroom discipline rapidly vanishing. armed forces headquarters cautiously admitted a new high in desertions and awols. the consensus among psychiatrists and psychologists was that the condition stemmed from pathogenic causes. dr. murt raised his eyebrows when he read this. perhaps phyllis sutton was right, after all. the bulletin continued, "all clinical pathologists are requested to be alert to the presence of any unusual organisms discovered in body fluids or tissues examined. please report your findings to the u. s. public health service." murt found phyllis sutton at the microtome, finishing a wax section, and showed her the bulletin. "score one for woman's intuition," he smiled. "federal health service tends to agree with your theory." "now i _am_ eager to see those pictures," she said. * * * * * less than two hours later, a messenger brought the photomicrographs, and the two pathologists bent over them together. phyllis had submitted eighteen samples, six of which were controls taken from healthy, unafflicted subjects. per her instructions, smears of the specimens in various degrees of dilution had been photographed through the great electron microscope. [illustration] murt muttered to himself as they compared the controls with the "infected specimens." the "healthy" samples were relatively clear, except for minute protein matter. conversely, all twelve suspect specimens swarmed with shadowy six-sided dots. phyllis' eyes widened. "there is something there! do you suppose it could be the love bug?" "love bug?" "certainly. that bulletin didn't go into the psychologists' findings. the diagnosticians downstairs say that the symptoms appear to be no more than complaints of the lovesick." "are you back on the pantie-raid theme again?" "i've never been off it," she replied. "from the first, i've had a notion that some organism was increasing glandular activity. excess emotionalism often originates in overstimulated glands." "of course, but mental attitudes can trigger the glands, and they are interacting. how do you separate the effects? how could you guess that an organism was responsible?" she shrugged. "it was a possibility within our specialty, so i set out to prove or disprove it. from the appearance of these photographs, i don't think we have _disproved_ it." it was a properly cautious statement that pleased murt. they were a long way from proving that their newly discovered virus was the culprit, but the research had definitely produced a question mark. murt ordered copies of the photomicrographs from ebert industrial labs and arranged for a complete dossier to be forwarded to the u. s. health service. that night, he was startled by a headline and lead story that quoted the government bulletin. the science editor had a field day, tying in speculation that "doctors suspect love bug epidemic." * * * * * the next day, three reporters called upon him, each with the same query. "it's rumored that you are doing research on the love bug, dr. murt. anything to report?" he shooed them out angrily, after learning that someone at ebert labs had given them the tip. phyllis smiled at him as he slammed the door after the last reporter. "you still discount the love bug idea, don't you?" she asked. "i dislike sensationalism in a matter like this," he said. "even if their assumptions were true, i wouldn't like it." "you can't blame the papers. they're starved for some explanation. i pity your passion for anonymity if your virus proves to be the causative factor." "_my_ virus?" "certainly. the whole project is under your auspices and direction." "see here, phyl, _you_ did the work." "don't you dare mention my name," she said. "you're my superior and senior pathologist and it's your duty to protect me against the press. i don't want columnists popping out of my bathroom any more than you do." murt gave up. "the argument is entirely anticipatory," he pointed out. "the virus might turn out to be a batch of dormant german measles. would you consider having dinner with me tonight?" "why?" she shot the question back at him like a rebounding tennis ball. "answer that first!" murt opened his mouth. he could not recall ever hearing such a rude rejoinder to an invitation to dinner. not that there had been a plethora of amenities between them, but this was unthinkable! the question was, why _should_ she have dinner with him? give her eight good reasons. what was his motive in asking her? in one word, _why_? murt searched her face, but only a quiet interest showed in her expression. "why does any man invite any woman to dinner?" he countered. "you aren't _any_ man, dr. murt. nor am i _any_ woman. i want your specific reason for inviting me to dinner. is it to discuss professional matters or--what?" "good lord, dr. sutton!" he followed her lead in using the formal address. "man is a social animal! i would enjoy your company at dinner, that's all. at least, i thought i would." she looked at him unrelentingly. "if the talk will be about baseball, books or billiards, i'm for it. if it's to be moonlight, roses and dimmed lights--no sale." * * * * * it was like asking one's grandfather for a date. his regard for her highly professional approach turned to resentment. after all, she was a woman, a woman who persisted in belting her smock too tightly and wearing sheer nylons. why this absurd revulsion at his casual acknowledgment of her sex? he almost withdrew the invitation, but changed his mind at the last moment. "you name the place and the subject for conversation." she nodded. "very well, i'll pick you up at seven." he had his date--with an emancipated female, and she didn't let him forget it during the whole meal. the restaurant she picked was expensive, but about as romantic as a bus depot. she ordered beer instead of a cocktail, toyed wordlessly with a $5.00 steak, and argued over the check. only as they were preparing to leave did she betray a sign of femininity. a platinum blonde, two tables away, had been eying murt. suddenly, she lurched to her feet without a word to her escort, staggered over to the pathologist, slurred, "you're what i've b'n lookin' for all m'life," and planted a wet alcoholic kiss on his mouth before he could defend himself. her escort peeled her away with sad-eyed apologies. there was no jealousy or anger in his face, only a deep hurt. "she--she isn't well, i think," he said. "you know, this new--whatever it is that's going around." murt wiped off the lipstick and looked at phyllis, expecting to find at best sardonic amusement, but she seemed pale and annoyed. "i'm sorry i brought you here," she said. "think nothing of it," murt told her. "you heard the man. this is what's going around. do you think i'll catch it?" phyllis wasn't amused. she did let him ride the taxi to her apartment, but bade him a terse goodby at the door. except for the incident of the blonde and phyl's reaction, the evening had been a bust. murt wondered how he had ever visualized her as a warm-blooded, responsive female. he smiled at the evening of torment she had once given him. she was entirely frigid or else so leery of men that she might as well have been one herself. iv the following morning, he presided at a specialists' conference at the hospital, during which he revealed the results of the blood research. they had all read the health service bulletin and were sharply interested in the photomicrographs. when the meeting was over, feldman, the bacteriologist, and stitchell, an endocrinologist, volunteered to work with murt. they gave phyllis' "gland-irritation" theory more credence than murt. he outlined a program. both agreed to take the problem back to their own departments. the conference set murt behind in his work and he spoke scarcely five words to his assistant until he was ready to leave. as he finished scrubbing up, she handed him an early edition of the _times_. "local doctor isolates love bug!" the story was sketchy and not half so positive as the headline, but it did name him and high dawn hospital, and described the new virus. he stared at phyllis sutton. "did you--" "of course not. the reporters were here, but i sent them away. i told them we were medicine men, not tobacco men." "your name isn't even mentioned," he said suspiciously. "you signed the report to the health service," she pointed out. "the leak probably came at that end." she put her hand on his arm. "it wasn't your fault." his fury cooled as he noted her gesture. then she realized that he was looking down at her hand and withdrew it quickly. the next few days were blindly busy. a note from the government acknowledged receipt of his report and pictures, and was followed by a message that the virus could not be identified. the implication was that there was a strong possibility that it was the causative factor in the new _malaise_. * * * * * murt devoted more attention to the joint laboratory work on the virus. the newspapers continued to come up with confidential information they shouldn't have had, and they dubbed the love bug, _murt's virus_. the name stuck, and the pathologist found himself famous overnight. phyllis continued to force all the credit upon him, on threat of transferring out if he violated her confidence. except for the nuisance of dodging reporters, the accolade was not entirely unpleasant. his pictures--old ones, lord knew where they had dug them up--began appearing in the papers. instead of reproving him, the hospital board voted him a substantial salary increase and gave him a free hand in directing the research. a government grant was obtained to supplement his budget, and the work picked up speed. necessarily, the lead that phyllis sutton's early research had given them on the rest of the medical world was maintained largely because of the time lag in disseminating the information contained in murt's report, and the additional time it took for other clinical laboratories to confirm it. cages of experimental animals began arriving along with several additional specialists. ebert industrial labs, contrite over the original information leak, made available their electron microscope, and murt assigned the new toxicologist to work over there with feldman, the bacteriologist, studying ways to weaken or destroy the virus. stitchell, the endocrinologist, and a trio of psychologists from the state university began injecting monkeys with virus when feldman found he could propagate it in sterile medium. on september 12, 1961, dr. sylvester murt became a victim of the virus which bore his name. * * * * * he had slept poorly and he awakened feeling empty. his first dismal thought was that phyl wouldn't be at the hospital this morning. he had told her to spend a few hours down at ebert labs, getting notes on their progress. as he shaved, dressed and breakfasted, this thought preyed on his mind. it wasn't until he had put in half the morning clock-watching and door-gazing that he stepped outside his wretchedness and took an objective look at his feelings. it wasn't that he missed her help--he had plenty of personnel at his disposal now. he simply longed for the sight of her, for the sound of her voice and her heels clipping busily around his office-lab. _here we go again_, he thought, and then he came up short. the feeling was similar to the silly evening of infatuation he had allowed himself, but it was intensified tenfold. the burn in his stomach was almost painful. he caught himself sighing like a frustrated poet, and he grew to hate the sight of the hall door, through which she kept right on not appearing. when she failed to show up by 11:30, and he gagged over his lunch, he knew he was sick. he had murt's virus! now what? did knowing you had it make it any easier? easier to make a damned fool of himself, he supposed. he'd have to take hold of himself or he'd scare her off the grounds. at the thought of her leaving him for good, something like a dull crosscut saw hacked across his diaphragm, and he dropped his forkful of potato salad. back at his office, he diluted 30 cc of pure grain alcohol with water and swallowed it. some of the distress and anxiety symptoms were relieved, and he bent determinedly to his work. when her distinctive steps finally came through the door, he refused to raise his head from the binocular microscope. "how are they making out over there?" he mumbled. "it's slow," she said, dropping her notes on his desk. "they're halfway through the sulfas so far. no results yet." * * * * * relief at having her near him again was so great, it was almost frightening. but he gained equal pleasure from finding his self-control adequate to keep from raising his head and devouring her with his eyes. "sylvester," her voice came from behind his stool, "if you don't mind, i'd rather not go over there again." "why not?" her voice was strangely soft. "because i--i missed...." at that instant, her hand rested on his shoulder and it sent a charge of high voltage through him. he stiffened. "_don't do that!_" he said sharply. he could see her reflection dimly in the window glass. she took a step backward. "what's the matter, sylvester?" he fought back the confusion in his brain, considered explaining that he was making a fine adjustment on the scope. but he didn't. he turned and let her have it. "because i've got the virus," he said in a flat voice. "and the object of my affection--or infected, overstimulated glands--is _you_!" "oh, dear! that blonde at the restaurant...." phyl's face was pale, but she composed her features quickly. "do you want me to leave?" "lord no! that magnifies the symptoms. stay with me and--and just be yourself. i won't bother you. if i lay a finger on you, clobber me." "have you had your blood tested?" "i don't have to. i've got all the symp--" he broke off, realizing that he was taking for granted that the new virus _was_ the cause of his feeling. clinically, this was nowhere near proved yet. slowly he rolled up his sleeve above the elbow. he dipped a swatch of gauze in alcohol and swabbed a vein. "all right, phyl, you're the doctor. make with the syringe." * * * * * by nightfall, murt came to understand the reasons for the increase in industrial accidents, absenteeism and the rest of the social effects of the "mild" epidemic. phyllis sutton was in his mind constantly. he deliberately did not look at her. but he was aware of her every movement, the texture and shape of her hand when she handed him a slide, the scent of her powder, the sound of her heels. when she left the room, he found himself awaiting her return and conjecturing on what she was doing every moment. not that it was difficult to adjust his behavior--no, that was relatively easy. all he had to do was think about every remark he made to her, censoring word, inflection and tone of voice--and, by keeping his back to her, it was easy to prevent his eyes from darting glances at her profile and staring at the curve of her hip below the tight belt. by staying busy, he fought off the depression until he left for the club, when it closed in on him like an autumn fog. he stopped at the club bar. curly, the bald-headed bartender, eyed him curiously when he ordered a double scotch. "heavy going down at the hospital these days?" curly asked. murt envied him his relaxed, carefree expression. he nodded. "pretty busy. i suppose you're catching it, too. lot of people drowning their sorrows these days?" curly looked up at the clock. "you said it! in about a half hour, the place'll be loaded. this epidemic is going to run the distilleries dry if it doesn't end pretty soon." "does liquor help any?" "seems to--a little. it's the damnedest thing! everybody's in love with the wrong people--i mean ten times as bad as usual. of course, not everybody. take my wife--she's got it bad, but she's still in love with _me_. so it could be worse." * * * * * "what do you mean?" murt asked, raising his head. "i mean it's bad enough for the poor woman to have the guy she wants. it's the jealousy angle. every minute i'm away, she sits at home wondering if i'm faithful. calls me up six times a shift. i don't dare take her out anyplace. every time another female comes in sight, she starts worrying. kate's a damned good wife, always has been, or i wouldn't be putting up with it. that's what's happening to a lot of marriages. some guys get fed up and start looking around. about that time, the bug bites _them_ and look out, secretary!" "but it's not her fault," murt said emphatically. "i know," curly shrugged. "a lot of people don't make any allowances for it, though. you know peter, the elevator boy? he and his wife both got it. for a while it was okay, but i guess they finally drove themselves nuts, keeping tabs on each other. now they can't stand to be together and they can't stand to be apart. poor joker ran the cage past the basement limit-switch three times today and had to be bailed out of the shaft. mr. johnson said he'd fire him if he could get another boy." the implication was shocking to murt. he had supposed that unhappiness would stem principally from cases of unrequited love, such as his own, but it was apparent that the disease magnified the painful aspects of mutual love as well. over-possessiveness and jealousy were common reefs of marriage, so it was hardly illogical that the divorce courts were as busy as the marriage license bureaus, after all. * * * * * it helped a little to immerse himself in the troubles of others, but, after another double scotch, he went to his apartment and immediately fell into despondency. the desire to phone phyllis was almost overpowering, though he knew talking to her wouldn't help. instead, he dressed and went to dinner. the club boasted a fine chef, but the food tasted like mucilage. later, he went to the bar and drank excessively. yet he had to take a sedative to get to sleep. he awoke in a stupor at ten o'clock. his phone was jangling persistently. it was phyllis sutton, and her face showed sharp concern. "are you all right, sylvester?" for a moment his hangover dominated, but then it all came back. "good morning! i'm _great_!" he moaned. "stitchell and the new toxicologist think they have something to report," she said. "so do i. alcohol is positively not the answer." "this is important. your suggestion on the sulfa series seems to have paid off." "i'll be right over," he said, "as soon as i amputate my head." "come down to the zoo. i'll be there." the thought of a remedy that might relieve him was a fair hangover cure. he dressed quickly and even managed to swallow a little coffee and toast. v at the hospital, he went directly to the "zoo" in the basement. a knot of personnel, including phyllis, peterson, the toxicologist, and feldman, opened to admit him to the cage under their inspection. a quick glance at the control cages showed no change in the undoctored monkeys. males and females were paired off, huddling together miserably, chattering and sadly rubbing their heads together. each couple eyed the other couples suspiciously. even here, the overpossessiveness was evident, and murt cringed from the pitiful, disconsolate expressions. the cage before him, however, appeared normally animated. the monks were feeding and playing happily. feldman was grinning. "had to try a new derivative, sylvester, but the sulfa series was the right approach." murt stared at the cage, redeyed. "hadn't realized you succeeded in producing the symptoms in monkeys." phyllis said, "why, i gave you that report yester--" she broke off with an understanding glance. peterson was exclaiming, "i never saw such a rapid-acting remedy! and so far, there's no evidence of toxic effect." "it must absorb directly into the gland tissue," feldman added. "hardly had time to materially reduce the virus content significantly." murt murmured words of congratulations to them, turned on his heel and stalked out. phyllis followed him to his office. "get me some of the stuff and notes on the dosages they administered," he ordered. "certainly," she said. "but why didn't you ask--_dr. murt, you aren't going to try it on yourself?_" "why not?" he barked hoarsely. "it'll be weeks before we can determine if it's safe," she protested, horrified. "we haven't got weeks. people are falling apart. this thing's contagious." even while murt said it, he felt it was the wrong approach. he knew his own perspective was shot, but phyllis would probably try to protect him against himself. she did not. instead, her face softened with sympathy and something else he refused to identify. she said, "i'll be right back." * * * * * the pressure in his head throbbed down his neck into his body. he wanted her so much, it was difficult to resist following her out into the hall. she returned in a few minutes with a 500-cc glass-stoppered reagent bottle half full of a milky fluid. "oral administration?" he asked. she nodded. "fifteen cc for the monkeys." she secured a small beaker and a tapered graduate from the glassware cabinet and set them before him. he poured 50 cc into the graduated measure and transferred it to the beaker. [illustration] "what do they call it?" he asked. "sulfa-tetradine," she replied. "one of a series peterson was testing. there is no physiological data on it yet. all he knows is that it inhibited the virus in culture. so they tried it on the monkeys." murt raised the beaker to his lips. it was against every sensible tenet of scientific procedure. he was amazed that phyllis was silent as he swallowed the bland, chalky fluid. he heard a clink. turning, he saw her raising the graduate to her lips. in it was a like quantity of sulfa-tetradine. "what are you doing?" he half-shouted. "we don't need a test-control!" "i'm not a control," she said softly, touching her lips with a scrap of gauze. "i've had the virus for months." he stared at her unbelievingly. "how do you know?" "one of the first test samples was my own blood," she said. "you saw it. it was one of the twelve positive." "but the symptoms--you don't show a sign of--" "thanks," she said. "i started to break down yesterday, but you didn't notice. you see, you are my fixation and when you told me that you had it, too, i--" "_your_ fixation!" the beaker slipped from his fingers and smashed to the tile. "_you're in love with me?_" her arms hung loosely at her sides and tears rimmed her eyes. "pathologically or otherwise, i've been a case since before i started the blood tests." they moved together and clung to each other. "phyl, phyl--why didn't you tell me?" * * * * * fiercely, she closed his lips with her own, and her fingers dug deeply into his shoulders. his arms pulled her closer yet, trying to fill the void in him that was greater than the universe. for a long minute, the knowledge of her love and physical contact with her straining body dispelled the bleak loneliness. when their lips parted, they gasped for breath. it was no good. it was like tearing at an itching insect bite with your fingernails. the relief was only momentary, and it left the wound bleeding and more irritated than ever. even if they were married--look at peter at the club--peter and his wife, mutually in love and completely miserable. it wasn't normal love. it was the damned virus! as well argue with gravity. he tried to tell her, but he couldn't make her understand. her restraint had been magnificent, but when the dam broke, it was beyond stopping the flood of her emotion. and now he couldn't believe it himself. nothing this wonderful could be destroyed by mere misunderstanding. he cursed the years of his celibacy. all that time wasted--lost! it was six o'clock before they reached her apartment. the license bureau had been a mob scene. hours more, upstairs in the city hall waiting for the judge, while they held hands like a pair of college sophomores, staring into each others' eyes, drinking, drinking the elixir of adoration with a thirst that wouldn't be sated. phyllis weakened first. in the cab, after the ceremony, she released his hand and wiped her damp forehead. then, in the elevator, murt felt himself relaxing. the alchemy of sustained passion had exhausted them both, he decided. as phyllis slipped the key in the door, she looked up at him in surprise. "do you know, i'm hungry. i'm starved--for the first time in months." murt discovered his own stomach was stirring with a prosaic pangful demand of its own. "we should have stopped to eat," he said, realizing they had forgotten lunch. "_steaks!_ i have some beauties in my freezer!" phyllis exclaimed. they peeled off their coats and she led him into the small kitchen. she pointed at the cupboard and silverware drawer. "set the table. we'll eat in five minutes." * * * * * slipping into an apron, she explored the freezer for meat and french fries, dropped them into the hf cooker and set the timer for 90 seconds. when it clicked off, she was emptying a transparent sack of prepared salad into a bowl. "coffee will be ready in 50 seconds, so let's eat," she announced. for minutes, they ate silently, ravenously, face to face in the little breakfast nook. murt had forgotten the pure animal pleasure of satisfying a neglected appetite, and so, apparently, had his wife. _wife!_ the thought jolted him. their eyes met, and he knew that the same thing was in her mind. the sulfa-tetradine! with the edge barely off his hunger, he stopped eating. she did, too. they sipped the steaming coffee and looked at each other. "i--feel better," phyllis said at last. "so do i." "i mean--i feel differently." he studied her face. it was new. the tenseness was gone and it was a beautiful face, with soft lips and intelligent eyes. but now the eyes were merely friendly. and it aroused no more than a casual pleasure in him, the pleasure of viewing a lovely painting or a perfect sunset. a peaceful intellectual rapport settled over them, inducing a physical lethargy. they spoke freely of their sensations, of the hypo-adrenal effects, and wondered that there was no unpleasant reaction. they decided that, initially at least, sulfa-tetradine was a miraculous success. murt thought he should go back to the hospital and work out a report right away. phyllis agreed and offered to accompany him, but he said she had better get a night's sleep. the next day would be hectic. after four hours at his desk, he called a taxi and, without hesitation, gave the address of his club. not until he fell wearily into bed did he remember it was his wedding night. by mutual agreement, the marriage was annulled the next day. feldman and peterson were gratified at the efficacy of their drug, but both were horrified that murt had chosen to experiment on himself. as usual, phyl had insisted on being left out of the report. * * * * * after a week of close observation, one of the monkeys was chloroformed and tissue-by-tissue examination was made by an army of histologists. blood samples showed completely clear of the virus, as did a recheck on murt's own blood. no deleterious effects could be detected, so the results were published through the government health service. it was the day before christmas before dr. sylvester murt first noticed the approaching symptoms of a relapse, or reinfection--he couldn't guess which. the past weeks had been pleasantly busy and, as acclaimed authority on murt's virus, he had had little time to think subjectively about his experience. sulfa-tetradine was now considered the specific for the affliction and was being produced and shipped by the carload all over the world. the press had over-generously insisted on giving him all the credit for the remedy as well as the isolation of the disease virus. he was an international hero. the warning of another attack came to him at 3:30 in the afternoon, when phyllis sutton was leaving. she stuck her head back in the door and gave him an uncommonly warm smile and cried, "merry christmas, doctor!" he waved at her and, as the door closed, caught his breath. there was the burn in his stomach again. it passed away and he refused to give it further thought. his own cab wound its way through the heavy christmas eve traffic an hour before store-closing time. finally, the vehicle stalled in a jam. it was only six blocks to his club, so murt paid off the driver and walked. part of his strategy of bachelorhood had been to ignore christmas and the other sentimental seasons, when loneliness costs many a man his independence. but now it was impossible to ignore the snowflakes, the bustling, package-laden crowds and the street-corner santa clauses with their tinkling bells. * * * * * he found himself staring into department store windows at the gay decorations. a pair of shimmering, nearly invisible nylons caught his eye. they were the most impalpable of substances, only their bare outline visible against the white background. he thought of phyllis and, on impulse, went into the store and bought a pair. the clerk had to pick a size at random for him. outside, on the sidewalk, he stared at the prettily gift-wrapped package and finally acknowledged the tremor, the tension and the old ache in the region of his diaphragm. _relapse!_ he plodded three slushy blocks up a side-street before he found a cab. he gave phyllis sutton's address to the driver and sank back in the taxi as a wave of weakness overcame him. what if she weren't home? it was christmas eve. she would probably be visiting friends or relatives. but she wasn't. she opened the door under his impatient knock, and her eyes widened cordially. "sylvester!" she exclaimed. "merry christmas! is that for me?" she pointed to the package, clutched forgotten in his hands. "merry, hell!" he said dispiritedly. "i came to warn you to look out for a relapse. mine's been coming on all day." she drew him inside, made him take off his coat and sit down before she acknowledged his remark. the apartment was cozy, with a tiny christmas tree decorated in the window. she returned from the hall closet and sat beside him. "look what i did--on impulse," he said and tossed the package on her lap. "that's what really turned it on." she opened the nylons and looked up at him sideways. he continued unhappily, "i saw them in a window. made me think of you, and about that time the seizure began. i tried to kid myself that i was just getting you a little token of--of my esteem, but the symptoms are almost as bad as before already." * * * * * apparently she refused to accept the seriousness of the situation. her smile was fatuous, he thought, kissably fatuous. "don't you realize what this means?" he demanded. "peterson and feldman turned up a very distressing fact. sulfa-tetradine deposits out in the endocrines, so a single dose is all a person can take. this relapse of mine means we have it all to do over again." "think, dr. murt! just think a minute," she urged. "about what?" "if the sulfa deposits out in the very glands it's there to protect, how could you be suffering another attack?" his arms ached to reach out and emphasize his argument. "i don't know. all i know is how i feel. in a way, this is even worse, because--" "i know," phyllis said and perversely moved close to him. "my relapse came last tuesday when i bought you a tie for christmas. i sent a blood sample over to ebert labs right away. and do you know what?" "what?" murt asked in a bewildered fog. "it was negative. i don't have murt's virus." she slipped an arm around his waist and put her head on his shoulder. "all i've got is murt himself." contagion by katherine maclean [transcriber's note: this etext was produced from galaxy science fiction october 1950. extensive research did not uncover any evidence that the u.s. copyright on this publication was renewed.] minos was such a lovely planet. not a thing seemed wrong with it. excepting the food, perhaps. and a disease that wasn't really. it was like an earth forest in the fall, but it was not fall. the forest leaves were green and copper and purple and fiery red, and a wind sent patches of bright greenish sunlight dancing among the leaf shadows. the hunt party of the _explorer_ filed along the narrow trail, guns ready, walking carefully, listening to the distant, half familiar cries of strange birds. a faint crackle of static in their earphones indicated that a gun had been fired. "got anything?" asked june walton. the helmet intercom carried her voice to the ears of the others without breaking the stillness of the forest. "took a shot at something," explained george barton's cheerful voice in her earphones. she rounded a bend of the trail and came upon barton standing peering up into the trees, his gun still raised. "it looked like a duck." "this isn't central park," said hal barton, his brother, coming into sight. his green spacesuit struck an incongruous note against the bronze and red forest. "they won't all look like ducks," he said soberly. "maybe some will look like dragons. don't get eaten by a dragon, june," came max's voice quietly into her earphones. "not while i still love you." he came out of the trees carrying the blood sample kit, and touched her glove with his, the grin on his ugly beloved face barely visible in the mingled light and shade. a patch of sunlight struck a greenish glint from his fishbowl helmet. * * * * * they walked on. a quarter of a mile back, the space ship _explorer_ towered over the forest like a tapering skyscraper, and the people of the ship looked out of the viewplates at fresh winds and sunlight and clouds, and they longed to be outside. but the likeness to earth was danger, and the cool wind might be death, for if the animals were like earth animals, their diseases might be like earth diseases, alike enough to be contagious, different enough to be impossible to treat. there was warning enough in the past. colonies had vanished, and traveled spaceways drifted with the corpses of ships which had touched on some plague planet. the people of the ship waited while their doctors, in airtight spacesuits, hunted animals to test them for contagion. the four medicos, for june walton was also a doctor, filed through the alien homelike forest, walking softly, watching for motion among the copper and purple shadows. they saw it suddenly, a lighter moving copper patch among the darker browns. reflex action swung june's gun into line, and behind her someone's gun went off with a faint crackle of static, and made a hole in the leaves beside the specimen. then for a while no one moved. this one looked like a man, a magnificently muscled, leanly graceful, humanlike animal. even in its callused bare feet, it was a head taller than any of them. red-haired, hawk-faced and darkly tanned, it stood breathing heavily, looking at them without expression. at its side hung a sheath knife, and a crossbow was slung across one wide shoulder. they lowered their guns. "it needs a shave," max said reasonably in their earphones, and he reached up to his helmet and flipped the switch that let his voice be heard. "something we could do for you, mac?" the friendly drawl was the first voice that had broken the forest sounds. june smiled suddenly. he was right. the strict logic of evolution did not demand beards; therefore a non-human would not be wearing a three day growth of red stubble. still panting, the tall figure licked dry lips and spoke. "welcome to minos. the mayor sends greetings from alexandria." "english?" gasped june. "we were afraid you would take off again before i could bring word to you.... it's three hundred miles.... we saw your scout plane pass twice, but we couldn't attract its attention." * * * * * june looked in stunned silence at the stranger leaning against the tree. thirty-six light years--thirty-six times six trillion miles of monotonous space travel--to be told that the planet was already settled! "we didn't know there was a colony here," she said. "it is not on the map." "we were afraid of that," the tall bronze man answered soberly. "we have been here three generations and yet no traders have come." max shifted the kit strap on his shoulder and offered a hand. "my name is max stark, m.d. this is june walton, m.d., hal barton, m.d., and george barton, hal's brother, also m.d." "patrick mead is the name," smiled the man, shaking hands casually. "just a hunter and bridge carpenter myself. never met any medicos before." the grip was effortless but even through her airproofed glove june could feel that the fingers that touched hers were as hard as padded steel. "what--what is the population of minos?" she asked. he looked down at her curiously for a moment before answering. "only one hundred and fifty." he smiled. "don't worry, this isn't a city planet yet. there's room for a few more people." he shook hands with the bartons quickly. "that is--you are people, aren't you?" he asked startlingly. "why not?" said max with a poise that june admired. "well, you are all so--so--" patrick mead's eyes roamed across the faces of the group. "so varied." they could find no meaning in that, and stood puzzled. "i mean," patrick mead said into the silence, "all these--interesting different hair colors and face shapes and so forth--" he made a vague wave with one hand as if he had run out of words or was anxious not to insult them. "joke?" max asked, bewildered. june laid a hand on his arm. "no harm meant," she said to him over the intercom. "we're just as much of a shock to him as he is to us." she addressed a question to the tall colonist on outside sound. "what should a person look like, mr. mead?" he indicated her with a smile. "like you." june stepped closer and stood looking up at him, considering her own description. she was tall and tanned, like him; had a few freckles, like him; and wavy red hair, like his. she ignored the brightly humorous blue eyes. "in other words," she said, "everyone on the planet looks like you and me?" patrick mead took another look at their four faces and began to grin. "like me, i guess. but i hadn't thought of it before. i did not think that people could have different colored hair or that noses could fit so many ways onto faces. i was judging by my own appearance, but i suppose any fool can walk on his hands and say the world is upside down!" he laughed and sobered. "but then why wear spacesuits? the air is breathable." "for safety," june told him. "we can't take any chances on plague." pat mead was wearing nothing but a loin cloth and his weapons, and the wind ruffled his hair. he looked comfortable, and they longed to take off the stuffy spacesuits and feel the wind against their own skins. minos was like home, like earth.... but they were strangers. "plague," pat mead said thoughtfully. "we had one here. it came two years after the colony arrived and killed everyone except the mead families. they were immune. i guess we look alike because we're all related, and that's why i grew up thinking that it is the only way people can look." _plague._ "what was the disease?" hal barton asked. "pretty gruesome, according to my father. they called it the melting sickness. the doctors died too soon to find out what it was or what to do about it." "you should have trained for more doctors, or sent to civilization for some." a trace of impatience was in george barton's voice. pat mead explained patiently, "our ship, with the power plant and all the books we needed, went off into the sky to avoid the contagion, and never came back. the crew must have died." long years of hardship were indicated by that statement, a colony with electric power gone and machinery stilled, with key technicians dead and no way to replace them. june realized then the full meaning of the primitive sheath knife and bow. "any recurrence of melting sickness?" asked hal barton. "no." "any other diseases?" "not a one." max was eyeing the bronze red-headed figure with something approaching awe. "do you think all the meads look like that?" he said to june on the intercom. "i wouldn't mind being a mead myself!" * * * * * their job had been made easy by the coming of pat. they went back to the ship laughing, exchanging anecdotes with him. there was nothing now to keep minos from being the home they wanted, except the melting sickness, and, forewarned against it, they could take precautions. the polished silver and black column of the _explorer_ seemed to rise higher and higher over the trees as they neared it. then its symmetry blurred all sense of specific size as they stepped out from among the trees and stood on the edge of the meadow, looking up. "nice!" said pat. "beautiful!" the admiration in his voice was warming. "it was a yacht," max said, still looking up, "second hand, an old-time beauty without a sign of wear. synthetic diamond-studded control board and murals on the walls. it doesn't have the new speed drives, but it brought us thirty-six light years in one and a half subjective years. plenty good enough." the tall tanned man looked faintly wistful, and june realized that he had never had access to a full library, never seen a movie, never experienced luxury. he had been born and raised on minos. * * * * * "may i go aboard?" pat asked hopefully. max unslung the specimen kit from his shoulder, laid it on the carpet of plants that covered the ground and began to open it. "tests first," hal barton said. "we have to find out if you people still carry this so-called melting sickness. we'll have to de-microbe you and take specimens before we let you on board. once on, you'll be no good as a check for what the other meads might have." max was taking out a rack and a stand of preservative bottles and hypodermics. "are you going to jab me with those?" pat asked with interest. "you're just a specimen animal to me, bud!" max grinned at pat mead, and pat grinned back. june saw that they were friends already, the tall pantherish colonist, and the wry, black-haired doctor. she felt a stab of guilt because she loved max and yet could pity him for being smaller and frailer than pat mead. "lie down," max told him, "and hold still. we need two spinal fluid samples from the back, a body cavity one in front, and another from the arm." pat lay down obediently. max knelt, and, as he spoke, expertly swabbed and inserted needles with the smooth speed that had made him a fine nerve surgeon on earth. high above them the scout helioplane came out of an opening in the ship and angled off toward the west, its buzz diminishing. then, suddenly, it veered and headed back, and reno unrich's voice came tinnily from their earphones: "what's that you've got? hey, what are you docs doing down there?" he banked again and came to a stop, hovering fifty feet away. june could see his startled face looking through the glass at pat. hal barton switched to a narrow radio beam, explained rapidly and pointed in the direction of alexandria. reno's plane lifted and flew away over the odd-colored forest. "the plane will drop a note on your town, telling them you got through to us," hal barton told pat, who was sitting up watching max dexterously put the blood and spinal fluids into the right bottles without exposing them to air. "we won't be free to contact your people until we know if they still carry melting sickness," max added. "you might be immune so it doesn't show on you, but still carry enough germs--if that's what caused it--to wipe out a planet." "if you do carry melting sickness," said hal barton, "we won't be able to mingle with your people until we've cleared them of the disease." "starting with me?" pat asked. "starting with you," max told him ruefully, "as soon as you step on board." "more needles?" "yes, and a few little extras thrown in." "rough?" "it isn't easy." a few minutes later, standing in the stalls for spacesuit decontamination, being buffeted by jets of hot disinfectant, bathed in glares of sterilizing ultraviolet radiation, june remembered that and compared pat mead's treatment to theirs. in the _explorer_, stored carefully in sealed tanks and containers, was the ultimate, multi-purpose cureall. it was a solution of enzymes so like the key catalysts of the human cell nucleus that it caused chemical derangement and disintegration in any non-human cell. nothing could live in contact with it but human cells; any alien intruder to the body would die. nucleocat cureall was its trade name. but the cureall alone was not enough for complete safety. plagues had been known to slay too rapidly and universally to be checked by human treatment. doctors are not reliable; they die. therefore spaceways and interplanetary health law demanded that ship equipment for guarding against disease be totally mechanical in operation, rapid and efficient. somewhere near them, in a series of stalls which led around and around like a rabbit maze, pat was being herded from stall to stall by peremptory mechanical voices, directed to soap and shower, ordered to insert his arm into a slot which took a sample of his blood, given solutions to drink, bathed in germicidal ultraviolet, shaken by sonic blasts, breathing air thick with sprays of germicidal mists, being directed to put his arms into other slots where they were anesthesized and injected with various immunizing solutions. finally, he would be put in a room of high temperature and extreme dryness, and instructed to sit for half an hour while more fluids were dripped into his veins through long thin tubes. all legal spaceships were built for safety. no chance was taken of allowing a suspected carrier to bring an infection on board with him. * * * * * june stepped from the last shower stall into the locker room, zipped off her spacesuit with a sigh of relief, and contemplated herself in a wall mirror. red hair, dark blue eyes, tall.... "i've got a good figure," she said thoughtfully. max turned at the door. "why this sudden interest in your looks?" he asked suspiciously. "do we stand here and admire you, or do we finally get something to eat?" "wait a minute." she went to a wall phone and dialed it carefully, using a combination from the ship's directory. "how're you doing, pat?" the phone picked up a hissing of water or spray. there was a startled chuckle. "voices, too! hello, june. how do you tell a machine to go jump in the lake?" "are you hungry?" "no food since yesterday." "we'll have a banquet ready for you when you get out," she told pat and hung up, smiling. pat mead's voice had a vitality and enjoyment which made shipboard talk sound like sad artificial gaiety in contrast. they looked into the nearby small laboratory where twelve squealing hamsters were protestingly submitting to a small injection each of pat's blood. in most of them the injection was followed by one of antihistaminics and adaptives. otherwise the hamster defense system would treat all non-hamster cells as enemies, even the harmless human blood cells, and fight back against them violently. one hamster, the twelfth, was given an extra large dose of adaptive, so that if there were a disease, he would not fight it or the human cells, and thus succumb more rapidly. "how ya doing, george?" max asked. "routine," george barton grunted absently. on the way up the long spiral ramps to the dining hall, they passed a viewplate. it showed a long scene of mountains in the distance on the horizon, and between them, rising step by step as they grew farther away, the low rolling hills, bronze and red with patches of clear green where there were fields. someone was looking out, standing very still, as if she had been there a long time--bess st. clair, a canadian woman. "it looks like winnipeg," she told them as they paused. "when are you doctors going to let us out of this blithering barberpole? look," she pointed. "see that patch of field on the south hillside, with the brook winding through it? i've staked that hillside for our house. when do we get out?" * * * * * reno ulrich's tiny scout plane buzzed slowly in from the distance and began circling lazily. "sooner than you think," max told her. "we've discovered a castaway colony on the planet. they've done our tests for us by just living here. if there's anything here to catch, they've caught it." "people on minos?" bess's handsome ruddy face grew alive with excitement. "one of them is down in the medical department," june said. "he'll be out in twenty minutes." "may i go see him?" "sure," said max. "show him the way to the dining hall when he gets out. tell him we sent you." "right!" she turned and ran down the ramp like a small girl going to a fire. max grinned at june and she grinned back. after a year and a half of isolation in space, everyone was hungry for the sight of new faces, the sound of unfamiliar voices. * * * * * they climbed the last two turns to the cafeteria, and entered to a rich subdued blend of soft music and quiet conversations. the cafeteria was a section of the old dining room, left when the rest of the ship had been converted to living and working quarters, and it still had the original finely grained wood of the ceiling and walls, the sound absorbency, the soft music spools and the intimate small light at each table where people leisurely ate and talked. they stood in line at the hot foods counter, and behind her june could hear a girl's voice talking excitedly through the murmur of conversation. "--new man, honest! i saw him through the viewplate when they came in. he's down in the medical department. a real frontiersman." the line drew abreast of the counters, and she and max chose three heaping trays, starting with hydroponic mushroom steak, raised in the growing trays of water and chemicals; sharp salad bowl with rose tomatoes and aromatic peppers; tank-grown fish with special sauce; four different desserts, and assorted beverages. presently they had three tottering trays successfully maneuvered to a table. brant st. clair came over. "i beg your pardon, max, but they are saying something about reno carrying messages to a colony of savages, for the medical department. will he be back soon, do you know?" max smiled up at him, his square face affectionate. everyone liked the shy canadian. "he's back already. we just saw him come in." "oh, fine." st. clair beamed. "i had an appointment with him to go out and confirm what looks like a nice vein of iron to the northeast. have you seen bess? oh--there she is." he turned swiftly and hurried away. a very tall man with fiery red hair came in surrounded by an eagerly talking crowd of ship people. it was pat mead. he stood in the doorway, alertly scanning the dining room. sheer vitality made him seem even larger than he was. sighting june, he smiled and began to thread toward their table. "look!" said someone. "there's the colonist!" shelia, a pretty, jeweled woman, followed and caught his arm. "did you _really_ swim across a river to come here?" overflowing with good-will and curiosity, people approached from all directions. "did you actually walk three hundred miles? come, eat with us. let me help choose your tray." everyone wanted him to eat at their table, everyone was a specialist and wanted data about minos. they all wanted anecdotes about hunting wild animals with a bow and arrow. "he needs to be rescued," max said. "he won't have a chance to eat." june and max got up firmly, edged through the crowd, captured pat and escorted him back to their table. june found herself pleased to be claiming the hero of the hour. * * * * * pat sat in the simple, subtly designed chair and leaned back almost voluptuously, testing the way it gave and fitted itself to him. he ran his eyes over the bright tableware and heaped plates. he looked around at the rich grained walls and soft lights at each table. he said nothing, just looking and feeling and experiencing. "when we build our town and leave the ship," june explained, "we will turn all the staterooms back into the lounges and ballrooms and cocktail bars that used to be inside." "oh, i'm not complaining," pat said negligently. he cocked his head to the music, and tried to locate its source. "that's big of you," said max with gentle irony. they fell to, pat beginning the first meal he had had in more than a day. most of the other diners finished when they were halfway through, and began walking over, diffidently at first, then in another wave of smiling faces, handshakes, and introductions. pat was asked about crops, about farming methods, about rainfall and floods, about farm animals and plant breeding, about the compatibility of imported earth seeds with local ground, about mines and strata. there was no need to protect him. he leaned back in his chair and drawled answers with the lazy ease of a panther; where he could think of no statistic, he would fill the gap with an anecdote. it developed that he enjoyed spinning campfire yarns and especially being the center of interest. between bouts of questions, he ate with undiminished and glowing relish. june noticed that the female specialists were prolonging the questions more than they needed, clustering around the table laughing at his jokes, until presently pat was almost surrounded by pretty faces, eager questions, and chiming laughs. shelia the beautiful laughed most chimingly of all. june nudged max, and max shrugged indifferently. it wasn't anything a man would pay attention to, perhaps. but june watched pat for a moment more, then glanced uneasily back to max. he was eating and listening to pat's answers and did not feel her gaze. for some reason max looked almost shrunken to her. he was shorter than she had realized; she had forgotten that he was only the same height as herself. she was dimly aware of the clear lilting chatter of female voices increasing at pat's end of the table. "that guy's a menace," max said, and laughed to himself, cutting another slice of hydroponic mushroom steak. "what's eating you?" he added, glancing aside at her when he noticed her sudden stillness. "nothing," she said hastily, but she did not turn back to watching pat mead. she felt disloyal. pat was only a superb animal. max was the man she loved. or--was he? of course he was, she told herself angrily. they had gone colonizing together because they wanted to spend their lives together; she had never thought of marrying any other man. yet the sense of dissatisfaction persisted, and along with it a feeling of guilt. len marlow, the protein tank-culture technician responsible for the mushroom steaks, had wormed his way into the group and asked pat a question. now he was saying, "i don't dig you, pat. it sounds like you're putting the people into the tanks instead of the vegetables!" he glanced at them, looking puzzled. "see if you two can make anything of this. it sounds medical to me." pat leaned back and smiled, sipping a glass of hydroponic burgundy. "wonderful stuff. you'll have to show us how to make it." len turned back to him. "you people live off the country, right? you hunt and bring in steaks and eat them, right? well, say i have one of those steaks right here and i want to eat it, what happens?" * * * * * "go ahead and eat it. it just wouldn't digest. you'd stay hungry." "why?" len was aggrieved. "chemical differences in the basic protoplasm of minos. different amino linkages, left-handed instead of right-handed molecules in the carbohydrates, things like that. nothing will be digestible here until you are adapted chemically by a little test-tube evolution. till then you'd starve to death on a full stomach." pat's side of the table had been loaded with the dishes from two trays, but it was almost clear now and the dishes were stacked neatly to one side. he started on three desserts, thoughtfully tasting each in turn. "test-tube evolution?" max repeated. "what's that? i thought you people had no doctors." "it's a story." pat leaned back again. "alexander p. mead, the head of the mead clan, was a plant geneticist, a very determined personality and no man to argue with. he didn't want us to go through the struggle of killing off all minos plants and putting in our own, spoiling the face of the planet and upsetting the balance of its ecology. he decided that he would adapt our genes to this planet or kill us trying. he did it all right.'" "did which?" asked june, suddenly feeling a sourceless prickle of fear. "adapted us to minos. he took human cells--" * * * * * she listened intently, trying to find a reason for fear in the explanation. it would have taken many human generations to adapt to minos by ordinary evolution, and that only at a heavy toll of death and hunger which evolution exacts. there was a shorter way: human cells have the ability to return to their primeval condition of independence, hunting, eating and reproducing alone. alexander p. mead took human cells and made them into phagocytes. he put them through the hard savage school of evolution--a thousand generations of multiplication, hardship and hunger, with the alien indigestible food always present, offering its reward of plenty to the cell that reluctantly learned to absorb it. "leucocytes can run through several thousand generations of evolution in six months," pat mead finished. "when they reached to a point where they would absorb minos food, he planted them back in the people he had taken them from." "what was supposed to happen then?" max asked, leaning forward. "i don't know exactly how it worked. he never told anybody much about it, and when i was a little boy he had gone loco and was wandering ha-ha-ing around waving a test tube. fell down a ravine and broke his neck at the age of eighty." "a character," max said. why was she afraid? "it worked then?" "yes. he tried it on all the meads the first year. the other settlers didn't want to be experimented on until they saw how it worked out. it worked. the meads could hunt, and plant while the other settlers were still eating out of hydroponics tanks." "it worked," said max to len. "you're a plant geneticist and a tank culture expert. there's a job for you." "uh-_uh_!" len backed away. "it sounds like a medical problem to me. human cell control--right up your alley." "it is a one-way street," pat warned. "once it is done, you won't be able to digest ship food. i'll get no good from this protein. i ate it just for the taste." hal barton appeared quietly beside the table. "three of the twelve test hamsters have died," he reported, and turned to pat. "your people carry the germs of melting sickness, as you call it. the dead hamsters were injected with blood taken from you before you were de-infected. we can't settle here unless we de-infect everybody on minos. would they object?" "we wouldn't want to give you folks germs," pat smiled. "anything for safety. but there'll have to be a vote on it first." the doctors went to reno ulrich's table and walked with him to the hangar, explaining. he was to carry the proposal to alexandria, mingle with the people, be persuasive and wait for them to vote before returning. he was to give himself shots of cureall every two hours on the hour or run the risk of disease. * * * * * reno was pleased. he had dabbled in sociology before retraining as a mechanic for the expedition. "this gives me a chance to study their mores." he winked wickedly. "i may not be back for several nights." they watched through the viewplate as he took off, and then went over to the laboratory for a look at the hamsters. three were alive and healthy, munching lettuce. one was the control; the other two had been given shots of pat's blood from before he entered the ship, but with no additional treatment. apparently a hamster could fight off melting sickness easily if left alone. three were still feverish and ruffled, with a low red blood count, but recovering. the three dead ones had been given strong shots of adaptive and counter histamine, so their bodies had not fought back against the attack. june glanced at the dead animals hastily and looked away again. they lay twisted with a strange semi-fluid limpness, as if ready to dissolve. the last hamster, which had been given the heaviest dose of adaptive, had apparently lost all its hair before death. it was hairless and pink, like a still-born baby. "we can find no micro-organisms," george barton said. "none at all. nothing in the body that should not be there. leucosis and anemia. fever only for the ones that fought it off." he handed max some temperature charts and graphs of blood counts. june wandered out into the hall. pediatrics and obstetrics were her field; she left the cellular research to max, and just helped him with laboratory routine. the strange mood followed her out into the hall, then abruptly lightened. coming toward her, busily telling a tale of adventure to the gorgeous shelia davenport, was a tall, red-headed, magnificently handsome man. it was his handsomeness which made pat such a pleasure to look upon and talk with, she guiltily told herself, and it was his tremendous vitality.... it was like meeting a movie hero in the flesh, or a hero out of the pages of a book--deer-slayer, john clayton, lord greystoke. she waited in the doorway to the laboratory and made no move to join them, merely acknowledged the two with a nod and a smile and a casual lift of the hand. they nodded and smiled back. "hello, june," said pat and continued telling his tale, but as they passed he lightly touched her arm. "oh, pioneer!" she said mockingly and softly to his passing profile, and knew that he had heard. * * * * * that night she had a nightmare. she was running down a long corridor looking for max, but every man she came to was a big bronze man with red hair and bright blue eyes who grinned at her. the pink hamster! she woke suddenly, feeling as if alarm bells had been ringing, and listened carefully, but there was no sound. she had had a nightmare, she told herself, but alarm bells were still ringing in her unconscious. something was wrong. lying still and trying to preserve the images, she groped for a meaning, but the mood faded under the cold touch of reason. damn intuitive thinking! a pink hamster! why did the unconscious have to be so vague? she fell asleep again and forgot. they had lunch with pat mead that day, and after it was over pat delayed june with a hand on her shoulder and looked down at her for a moment. "i want you, june," he said and then turned away, answering the hails of a party at another table as if he had not spoken. she stood shaken, and then walked to the door where max waited. she was particularly affectionate with max the rest of the day, and it pleased him. he would not have been if he had known why. she tried to forget pat's blunt statement. june was in the laboratory with max, watching the growth of a small tank culture of the alien protoplasm from a minos weed, and listening to len marlow pour out his troubles. "and elsie tags around after that big goof all day, listening to his stories. and then she tells me i'm just jealous, i'm imagining things!" he passed his hand across his eyes. "i came away from earth to be with elsie.... i'm getting a headache. look, can't you persuade pat to cut it out, june? you and max are his friends." "here, have an aspirin," june said. "we'll see what we can do." "thanks." len picked up his tank culture and went out, not at all cheered. * * * * * max sat brooding over the dials and meters at his end of the laboratory, apparently sunk in thought. when len had gone, he spoke almost harshly. "why encourage the guy? why let him hope?" "found out anything about the differences in protoplasm?" she evaded. "why let him kid himself? what chance has he got against that hunk of muscle and smooth talk?" "but pat isn't after elsie," she protested. "every scatter-brained woman on this ship is trailing after pat with her tongue hanging out. brant st. clair is in the bar right now. he doesn't say what he is drinking about, but do you think pat is resisting all these women crowding down on him?" "there are other things besides looks and charm," she said, grimly trying to concentrate on a slide under her binocular microscope. "yeah, and whatever they are, pat has them, too. who's more competent to support a woman and a family on a frontier planet than a handsome bruiser who was born here?" "i meant," june spun around on her stool with unexpected passion, "there is old friendship, and there's fondness, and memories, and loyalty!" she was half shouting. "they're not worth much on the second-hand market," max said. he was sitting slumped on his lab stool, looking dully at his dials. "now _i'm_ getting a headache!" he smiled ruefully. "no kidding, a real headache. and over other people's troubles yet!" other people's troubles.... she got up and wandered out into the long curving halls. "i want you june," pat's voice repeated in her mind. why did the man have to be so overpoweringly attractive, so glaring a contrast to max? why couldn't the universe manage to run on without generating troublesome love triangles? * * * * * she walked up the curving ramps to the dining hall where they had eaten and drunk and talked yesterday. it was empty except for one couple talking forehead to forehead over cold coffee. she turned and wandered down the long easy spiral of corridor to the pharmacy and dispensary. it was empty. george was probably in the test lab next door, where he could hear if he was wanted. the automatic vendor of harmless euphorics, stimulants and opiates stood in the corner, brightly decorated in pastel abstract designs, with its automatic tabulator graph glowing above it. max had a headache, she remembered. she recorded her thumbprint in the machine and pushed the plunger for a box of aspirins, trying to focus her attention on the problem of adapting the people of the ship to the planet minos. an aquarium tank with a faint solution of histamine would be enough to convert a piece of human skin into a community of voracious active phagocytes individually seeking something to devour, but could they eat enough to live away from the rich sustaining plasma of human blood? after the aspirins, she pushed another plunger for something for herself. then she stood looking at it, a small box with three pills in her hand--theobromine, a heart strengthener and a confidence-giving euphoric all in one, something to steady shaky nerves. she had used it before only in emergency. she extended a hand and looked at it. it was trembling. damn triangles! while she was looking at her hand there was a click from the automatic drug vendor. it summed the morning use of each drug in the vendors throughout the ship, and recorded it in a neat addition to the end of each graph line. for a moment she could not find the green line for anodynes and the red line for stimulants, and then she saw that they went almost straight up. there were too many being used--far too many to be explained by jealousy or psychosomatic peevishness. this was an epidemic, and only one disease was possible! the disinfecting of pat had not succeeded. nucleocat cureall, killer of all infections, had not cured! pat had brought melting sickness into the ship with him! who had it? the drugs vendor glowed cheerfully, uncommunicative. she opened a panel in its side and looked in on restless interlacing cogs, and on the inside of the door saw printed some directions.... "to remove or examine records before reaching end of the reel--" after a few fumbling minutes she had the answer. in the cafeteria at breakfast and lunch, thirty-eight men out of the forty-eight aboard ship had taken more than his norm of stimulant. twenty-one had taken aspirin as well. the only woman who had made an unusual purchase was herself! she remembered the hamsters that had thrown off the infection with a short sharp fever, and checked back in the records to the day before. there was a short rise in aspirin sales to women at late afternoon. the women were safe. it was the men who had melting sickness! melting sickness killed in hours, according to pat mead. how long had the men been sick? * * * * * as she was leaving, jerry came into the pharmacy, recorded his thumbprint and took a box of aspirin from the machine. she felt all right. self-control was working well and it was pleasant still to walk down the corridor smiling at the people who passed. she took the emergency elevator to the control room and showed her credentials to the technician on watch. "medical emergency." at a small control panel in the corner was a large red button, precisely labeled. she considered it and picked up the control room phone. this was the hard part, telling someone, especially someone who had it--max. she dialed, and when the click on the end of the line showed he had picked the phone up, she told max what she had seen. "no women, just the men," he repeated. "that right?" "yes." "probably it's chemically alien, inhibited by one of the female sex hormones. we'll try sex hormone shots, if we have to. where are you calling from?" she told him. "that's right. give nucleocat cureall another chance. it might work this time. push that button." she went to the panel and pushed the large red button. through the long height of the _explorer_, bells woke to life and began to ring in frightened clangor, emergency doors thumped shut, mechanical apparatus hummed into life and canned voices began to give rapid urgent directions. a plague had come. * * * * * she obeyed the mechanical orders, went out into the hall and walked in line with the others. the captain walked ahead of her and the gorgeous shelia davenport fell into step beside her. "i look like a positive hag this morning. does that mean i'm sick? are we all sick?" june shrugged, unwilling to say what she knew. others came out of all rooms into the corridor, thickening the line. they could hear each room lock as the last person left it, and then, faintly, the hiss of disinfectant spray. behind them, on the heels of the last person in line, segments of the ship slammed off and began to hiss. they wound down the spiral corridor until they reached the medical treatment section again, and there they waited in line. "it won't scar my arms, will it?" asked shelia apprehensively, glancing at her smooth, lovely arms. the mechanical voice said, "next. step inside, please, and stand clear of the door." "not a bit," june reassured shelia, and stepped into the cubicle. inside, she was directed from cubicle to cubicle and given the usual buffeting by sprays and radiation, had blood samples taken and was injected with nucleocat and a series of other protectives. at last she was directed through another door into a tiny cubicle with a chair. "you are to wait here," commanded the recorded voice metallically. "in twenty minutes the door will unlock and you may then leave. all people now treated may visit all parts of the ship which have been protected. it is forbidden to visit any quarantined or unsterile part of the ship without permission from the medical officers." presently the door unlocked and she emerged into bright lights again, feeling slightly battered. she was in the clinic. a few men sat on the edge of beds and looked sick. one was lying down. brant and bess st. clair sat near each other, not speaking. approaching her was george barton, reading a thermometer with a puzzled expression. "what is it, george?" she asked anxiously. "some of the women have slight fever, but it's going down. none of the fellows have any--but their white count is way up, their red count is way down, and they look sick to me." she approached st. clair. his usually ruddy cheeks were pale, his pulse was light and too fast, and his skin felt clammy. "how's the headache? did the nucleocat treatment help?" "i feel worse, if anything." "better set up beds," she told george. "get everyone back into the clinic." "we're doing that," george assured her. "that's what hal is doing." she went back to the laboratory. max was pacing up and down, absently running his hands through his black hair until it stood straight up. he stopped when he saw her face, and scowled thoughtfully. "they are still sick?" it was more a statement than a question. she nodded. "the cureall didn't cure this time," he muttered. "that leaves it up to us. we have melting sickness and according to pat and the hamsters, that leaves us less than a day to find out what it is and learn how to stop it." suddenly an idea for another test struck him and he moved to the work table to set it up. he worked rapidly, with an occasional uncoordinated movement betraying his usual efficiency. it was strange to see max troubled and afraid. she put on a laboratory smock and began to work. she worked in silence. the mechanicals had failed. hal and george barton were busy staving off death from the weaker cases and trying to gain time for max and her to work. the problem of the plague had to be solved by the two of them alone. it was in their hands. another test, no results. another test, no results. max's hands were shaking and he stopped a moment to take stimulants. she went into the ward for a moment, found bess and warned her quietly to tell the other women to be ready to take over if the men became too sick to go on. "but tell them calmly. we don't want to frighten the men." she lingered in the ward long enough to see the word spread among the women in a widening wave of paler faces and compressed lips; then she went back to the laboratory. another test. there was no sign of a micro-organism in anyone's blood, merely a growing horde of leucocytes and phagocytes, prowling as if mobilized to repel invasion. * * * * * len marlow was wheeled in unconscious, with hal barton's written comments and conclusions pinned to the blanket. "i don't feel so well myself," the assistant complained. "the air feels thick. i can't breathe." june saw that his lips were blue. "oxygen short," she told max. "low red corpuscle count," max answered. "look into a drop and see what's going on. use mine; i feel the same way he does." she took two drops of max's blood. the count was low, falling too fast. breathing is useless without the proper minimum of red corpuscles in the blood. people below that minimum die of asphyxiation although their lungs are full of pure air. the red corpuscle count was falling too fast. the time she and max had to work in was too short. "pump some more co_{2} into the air system," max said urgently over the phone. "get some into the men's end of the ward." * * * * * she looked through the microscope at the live sample of blood. it was a dark clear field and bright moving things spun and swirled through it, but she could see nothing that did not belong there. "hal," max called over the general speaker system, "cut the other treatments, check for accelerating anemia. treat it like monoxide poisoning--co_{2} and oxygen." she reached into a cupboard under the work table, located two cylinders of oxygen, cracked the valves and handed one to max and one to the assistant. some of the bluish tint left the assistant's face as he breathed and he went over to the patient with reawakened concern. "not breathing, doc!" max was working at the desk, muttering equations of hemoglobin catalysis. "len's gone, doc," the assistant said more loudly. "artificial respiration and get him into a regeneration tank," said june, not moving from the microscope. "hurry! hal will show you how. the oxidation and mechanical heart action in the tank will keep him going. put anyone in a tank who seems to be dying. get some women to help you. give them hal's instructions." the tanks were ordinarily used to suspend animation in a nutrient bath during the regrowth of any diseased organ. it could preserve life in an almost totally destroyed body during the usual disintegration and regrowth treatments for cancer and old age, and it could encourage healing as destruction continued ... but they could not prevent ultimate death as long as the disease was not conquered. the drop of blood in june's microscope was a great, dark field, and in the foreground, brought to gargantuan solidity by the stereo effect, drifted neat saucer shapes of red blood cells. they turned end for end, floating by the humped misty mass of a leucocyte which was crawling on the cover glass. there were not enough red corpuscles, and she felt that they grew fewer as she watched. she fixed her eye on one, not blinking in fear that she would miss what might happen. it was a tidy red button, and it spun as it drifted, the current moving it aside in a curve as it passed by the leucocyte. then, abruptly, the cell vanished. june stared numbly at the place where it had been. behind her, max was calling over the speaker system again: "dr. stark speaking. any technician who knows anything about the life tanks, start bringing more out of storage and set them up. emergency." "we may need forty-seven," june said quietly. "we may need forty-seven," max repeated to the ship in general. his voice did not falter. "set them up along the corridor. hook them in on extension lines." his voice filtered back from the empty floors above in a series of dim echoes. what he had said meant that every man on board might be on the point of heart stoppage. * * * * * june looked blindly through the binocular microscope, trying to think. out of the corner of her eyes she could see that max was wavering and breathing more and more frequently of the pure, cold, burning oxygen of the cylinders. in the microscope she could see that there were fewer red cells left alive in the drop of his blood. the rate of fall was accelerating. she didn't have to glance at max to know how he would look--skin pale, black eyebrows and keen brown eyes slightly squinted in thought, a faint ironical grin twisting the bluing lips. intelligent, thin, sensitive, his face was part of her mind. it was inconceivable that max could die. he couldn't die. he couldn't leave her alone. she forced her mind back to the problem. all the men of the _explorer_ were at the same point, wherever they were. moving to max's desk, she spoke into the intercom system: "bess, send a couple of women to look through the ship, room by room, with a stretcher. make sure all the men are down here." she remembered reno. "sparks, heard anything from reno? is he back?" sparks replied weakly after a lag. "the last i heard from reno was a call this morning. he was raving about mirrors, and pat mead's folks not being real people, just carbon copies, and claiming he was crazy; and i should send him the psychiatrist. i thought he was kidding. he didn't call back." "thanks, sparks." reno was lost. max dialed and spoke to the bridge over the phone. "are you okay up there? forget about engineering controls. drop everything and head for the tanks while you can still walk." june went back to the work table and whispered into her own phone. "bess, send up a stretcher for max. he looks pretty bad." there had to be a solution. the life tanks could sustain life in a damaged body, encouraging it to regrow more rapidly, but they merely slowed death as long as the disease was not checked. the postponement could not last long, for destruction could go on steadily in the tanks until the nutritive solution would hold no life except the triumphant microscopic killers that caused melting sickness. there were very few red blood corpuscles in the microscope field now, incredibly few. she tipped the microscope and they began to drift, spinning slowly. a lone corpuscle floated through the center. she watched it as the current swept it in an arc past the dim off-focus bulk of the leucocyte. there was a sweep of motion and it vanished. for a moment it meant nothing to her; then she lifted her head from the microscope and looked around. max sat at his desk, head in hand, his rumpled short black hair sticking out between his fingers at odd angles. a pencil and a pad scrawled with formulas lay on the desk before him. she could see his concentration in the rigid set of his shoulders. he was still thinking; he had not given up. * * * * * "max, i just saw a leucocyte grab a red blood corpuscle. it was unbelievably fast." "leukemia," muttered max without moving. "galloping leukemia yet! that comes under the heading of cancer. well, that's part of the answer. it might be all we need." he grinned feebly and reached for the speaker set. "anybody still on his feet in there?" he muttered into it, and the question was amplified to a booming voice throughout the ship. "hal, are you still going? look, hal, change all the dials, change the dials, set them to deep melt and regeneration. one week. this is like leukemia. got it? this is like leukemia." june rose. it was time for her to take over the job. she leaned across his desk and spoke into the speaker system. "doctor walton talking," she said. "this is to the women. don't let any of the men work any more; they'll kill themselves. see that they all go into the tanks right away. set the tank dials for deep regeneration. you can see how from the ones that are set." two exhausted and frightened women clattered in the doorway with a stretcher. their hands were scratched and oily from helping to set up tanks. "that order includes you," she told max sternly and caught him as he swayed. max saw the stretcher bearers and struggled upright. "ten more minutes," he said clearly. "might think of an idea. something not right in this setup. i have to figure how to prevent a relapse, how the thing started." he knew more bacteriology than she did; she had to help him think. she motioned the bearers to wait, fixed a breathing mask for max from a cylinder of co_{2} and the opened one of oxygen. max went back to his desk. she walked up and down, trying to think, remembering the hamsters. the melting sickness, it was called. melting. she struggled with an impulse to open a tank which held one of the men. she wanted to look in, see if that would explain the name. melting sickness.... footsteps came and pat mead stood uncertainly in the doorway. tall, handsome, rugged, a pioneer. "anything i can do?" he asked. she barely looked at him. "you can stay out of our way. we're busy." "i'd like to help," he said. "very funny." she was vicious, enjoying the whip of her words. "every man is dying because you're a carrier, and you want to help." * * * * * he stood nervously clenching and unclenching his hands. "a guinea pig, maybe. i'm immune. all the meads are." "go away." god, why couldn't she think? what makes a mead immune? "aw, let 'im alone," max muttered. "pat hasn't done anything." he went waveringly to the microscope, took a tiny sliver from his finger, suspended it in a slide and slipped it under the lens with detached habitual dexterity. "something funny going on," he said to june. "symptoms don't feel right." after a moment he straightened and motioned for her to look. "leucocytes, phagocytes--" he was bewildered. "my own--" she looked in, and then looked back at pat in a growing wave of horror. "they're not your own, max!" she whispered. max rested a hand on the table to brace himself, put his eye to the microscope, and looked again. june knew what he saw. phagocytes, leucocytes, attacking and devouring his tissues in a growing incredible horde, multiplying insanely. _not his phagocytes! pat mead's!_ the meads' evolved cells had learned too much. they were contagious. and not pat mead's.... how much alike _were_ the meads?... mead cells contagious from one to another, not a disease attacking or being fought, but acting as normal leucocytes in whatever body they were in! the leucocytes of tall, red-headed people, finding no strangeness in the bloodstream of any of the tall, red-headed people. no strangeness.... a toti-potent leucocyte finding its way into cellular wombs. the womblike life tanks. for the men of the _explorer_, a week's cure with deep melting to de-differentiate the leucocytes and turn them back to normal tissue, then regrowth and reforming from the cells that were there. from the cells that _were_ there. _from the cells that were there...._ "pat--" "i know." pat began to laugh, his face twisted with sudden understanding. "i understand. i get it. i'm a contagious personality. that's funny, isn't it?" max rose suddenly from the microscope and lurched toward him, fists clenched. pat caught him as he fell, and the bewildered stretcher bearers carried him out to the tanks. * * * * * for a week june tended the tanks. the other women volunteered to help, but she refused. she said nothing, hoping her guess would not be true. "is everything all right?" elsie asked her anxiously. "how is jerry coming along?" elsie looked haggard and worn, like all the women, from doing the work that the men had always done. "he's fine," june said tonelessly, shutting tight the door of the tank room. "they're all fine." "that's good," elsie said, but she looked more frightened than before. june firmly locked the tank room door and the girl went away. the other women had been listening, and now they wandered back to their jobs, unsatisfied by june's answer, but not daring to ask for the actual truth. they were there whenever june went into the tank room, and they were still there--or relieved by others; june was not sure--when she came out. and always some one of them asked the unvarying question for all the others, and june gave the unvarying answer. but she kept the key. no woman but herself knew what was going on in the life tanks. then the day of completion came. june told no one of the hour. she went into the room as on the other days, locked the door behind her, and there was the nightmare again. this time it was reality and she wandered down a path between long rows of coffinlike tanks, calling, "max! max!" silently and looking into each one as it opened. but each face she looked at was the same. watching them dissolve and regrow in the nutrient solution, she had only been able to guess at the horror of what was happening. now she knew. they were all the same lean-boned, blond-skinned face, with a pin-feather growth of reddish down on cheeks and scalp. all horribly--and handsomely--the same. a medical kit lay carelessly on the floor beside max's tank. she stood near the bag. "max," she said, and found her throat closing. the canned voice of the mechanical mocked her, speaking glibly about waking and sitting up. "i'm sorry, max...." the tall man with rugged features and bright blue eyes sat up sleepily and lifted an eyebrow at her, and ran his hand over his red-fuzzed head in a gesture of bewilderment. "what's the matter, june?" he asked drowsily. she gripped his arm. "max--" he compared the relative size of his arm with her hand and said wonderingly, "you shrank." "i know, max. i know." he turned his head and looked at his arms and legs, pale blond arms and legs with a down of red hair. he touched the thick left arm, squeezed a pinch of hard flesh. "it isn't mine," he said, surprised. "but i can feel it." watching his face was like watching a stranger mimicking and distorting max's expressions. max in fear. max trying to understand what had happened to him, looking around at the other men sitting up in their tanks. max feeling the terror that was in herself and all the men as they stared at themselves and their friends and saw what they had become. "we're all pat mead," he said harshly. "all the meads are pat mead. that's why he was surprised to see people who didn't look like himself." "yes, max." "max," he repeated. "it's me, all right. the nervous system didn't change." his new blue eyes held hers. "my love didn't, either. did yours? did it, june?" "no, max." but she couldn't know yet. she had loved max with the thin, ironic face, the rumpled black hair and the twisted smile that never really hid his quick sympathy. now he was pat mead. could he also be max? "of course i still love you, darling." he grinned. it was still the wry smile of max, though fitting strangely on the handsome new blond face. "then it isn't so bad. it might even be pretty good. i envied him this big, muscular body. if pat or any of these meads so much as looks at you, i'm going to knock his block off. understand?" * * * * * she laughed and couldn't stop. it wasn't that funny. but it was still max, trying to be unafraid, drawing on humor. maybe the rest of the men would also be their old selves, enough so the women would not feel that their men were strangers. behind her, male voices spoke characteristically. she did not have to turn to know which was which: "this is one way to keep a guy from stealing your girl," that was len marlow; "i've got to write down all my reactions," hal barton; "now i can really work that hillside vein of metal," st. clair. then others complaining, swearing, laughing bitterly at the trick that had been played on them and their flirting, tempted women. she knew who they were. their women would know them apart, too. "we'll go outside," max said. "you and i. maybe the shock won't be so bad to the women after they see me." he paused. "you didn't tell them, did you?" "i couldn't. i wasn't sure. i--was hoping i was wrong." she opened the door and closed it quickly. there was a small crowd on the other side. "hello, pat," elsie said uncertainly, trying to look past them into the tank room before the door shut. "i'm not pat, i'm max," said the tall man with the blue eyes and the fuzz-reddened skull. "listen--" "good heavens, pat, what happened to your hair?" shelia asked. "i'm max," insisted the man with the handsome face and the sharp blue eyes. "don't you get it? i'm max stark. the melting sickness is mead cells. we caught them from pat. they adapted us to minos. they also changed us all into pat mead." the women stared at him, at each other. they shook their heads. "they don't understand," june said. "i couldn't have if i hadn't seen it happening, max." "it's pat," said shelia, dazedly stubborn. "he shaved off his hair. it's some kind of joke." max shook her shoulders, glaring down at her face. "i'm max. max stark. they all look like me. do you hear? it's funny, but it's not a joke. laugh for us, for god's sake!" "it's too much," said june. "they'll have to see." she opened the door and let them in. they hurried past her to the tanks, looking at forty-six identical blond faces, beginning to call in frightened voices: "jerry!" "harry!" "lee, where are you, sweetheart--" june shut the door on the voices that were growing hysterical, the women terrified and helpless, the men shouting to let the women know who they were. "it isn't easy," said max, looking down at his own thick muscles. "but you aren't changed and the other girls aren't. that helps." through the muffled noise and hysteria, a bell was ringing. "it's the airlock," june said. peering in the viewplate were nine meads from alexandria. to all appearances, eight of them were pat mead at various ages, from fifteen to fifty, and the other was a handsome, leggy, red-headed girl who could have been his sister. regretfully, they explained through the voice tube that they had walked over from alexandria to bring news that the plane pilot had contracted melting sickness there and had died. they wanted to come in. * * * * * june and max told them to wait and returned to the tank room. the men were enjoying their new height and strength, and the women were bewilderedly learning that they could tell one pat mead from another, by voice, by gesture of face or hand. the panic was gone. in its place was a dull acceptance of the fantastic situation. max called for attention. "there are nine meads outside who want to come in. they have different names, but they're all pat mead." they frowned or looked blank, and george barton asked, "why didn't you let them in? i don't see any problem." "one of them," said max soberly, "is a girl. _patricia_ mead. the girl wants to come in." there was a long silence while the implication settled to the fear center of the women's minds. shelia the beautiful felt it first. she cried, "no! please don't let her in!" there was real fright in her tone and the women caught it quickly. elsie clung to jerry, begging, "you don't want me to change, do you, jerry? you like me the way i am! tell me you do!" * * * * * the other girls backed away. it was illogical, but it was human. june felt terror rising in herself. she held up her hand for quiet, and presented the necessity to the group. "only half of us can leave minos," she said. "the men cannot eat ship food; they've been conditioned to this planet. we women can go, but we would have to go without our men. we can't go outside without contagion, and we can't spend the rest of our lives in quarantine inside the ship. george barton is right--there is no problem." "but we'd be changed!" shelia shrilled. "i don't want to become a mead! i don't want to be somebody else!" she ran to the inner wall of the corridor. there was a brief hesitation, and then, one by one, the women fled to that side, until there were only bess, june and four others left. "see!" cried shelia. "a vote! we can't let the girl in!" no one spoke. to change, to be someone else--the idea was strange and horrifying. the men stood uneasily glancing at each other, as if looking into mirrors, and against the wall of the corridor the women watched in fear and huddled together, staring at the men. one man in forty-seven poses. one of them made a beseeching move toward elsie and she shrank away. "no, jerry! i won't let you change me!" max stirred restlessly, the ironic smile that made his new face his own unconsciously twisting into a grimace of pity. "we men can't leave, and you women can't stay," he said bluntly. "why not let patricia mead in. get it over with!" june took a small mirror from her belt pouch and studied her own face, aware of max talking forcefully, the men standing silent, the women pleading. her face ... her own face with its dark blue eyes, small nose, long mobile lips ... the mind and the body are inseparable; the shape of a face is part of the mind. she put the mirror back. "i'd kill myself!" shelia was sobbing. "i'd rather die!" "you won't die," max was saying. "can't you see there's only one solution--" they were looking at max. june stepped silently out of the tank room, and then turned and went to the airlock. she opened the valves that would let in pat mead's sister. the arabian art of taming and training wild & vicious horses. by t. gilbert, bro. ramsey & co. printed and sold for the publisher by henry watkins printer, 225 & 227 west fifth street, cincinnati, ohio 1856. introduction. the first domestication of the horse, one of the greatest achievements of man in the animal kingdom, was not the work of a day; but like all other great accomplishments, was brought about by a gradual process of discoveries and experiments. he first subdued the more subordinate animals, on account of their being easily caught and tamed, and used for many years the mere drudges, the ox, the ass, and the camel, instead of the fleet and elegant horse. this noble animal was the last brought into subjection, owing, perhaps, to man's limited and inaccurate knowledge of his nature, and his consequent inability to control him. this fact alone is sufficient evidence of his superiority over all other animals. man, in all his inventions and discoveries, has almost invariably commenced with some simple principle, and gradually developed it from one degree of perfection to another. the first hint that we have of the use of electricity was franklin's drawing it from the clouds with his kite. now it is the instrument of conveying thought from mind to mind, with a rapidity that surpasses time. the great propelling power that drives the wheel of the engine over our land, and ploughs the ocean with our steamers, was first discovered escaping from a tea-kettle. and so the powers of the horse, second only to the powers of steam, became known to man only as experiments, and investigation revealed them. the horse, according to the best accounts we can gather, has been the constant servant of man for nearly four thousand years, ever rewarding him with his labor and adding to his comfort in proportion to his skill and manner of using him; but being to those who govern him by brute force, and know nothing of the beauty and delight to be gained from the cultivation of his finer nature, a fretful, vicious, and often dangerous servant; whilst to the arabs, whose horse is the pride of his life, and who governs him by the law of kindness, we find him to be quite a different animal. the manner in which he is treated from a foal gives him an affection and attachment for his master not known in any other country. the arab and his children, the mare and her foal, inhabit the tent together; and although the foal and the mare's neck are often pillows for the children to roll upon, no accident ever occurs, the mare being as careful of the children as of the colt. such is the mutual attachment between the horse and his master, that he will leave his companions at his master's call, ever glad to obey his voice. and when the arab falls from his horse, and is unable to rise again, he will stand by him and neigh for assistance; and if he lays down to sleep, as fatigue sometimes compels him to do in the midst of the desert, his faithful steed will watch over him, and neigh to arouse him if man or beast approaches. the arabs frequently teach their horses secret signs or signals, which they make use of on urgent occasions to call forth their utmost exertions. these are more efficient than the barbarous mode of urging them on with the spur and whip, a forcible illustration of which will be found in the following anecdote. a bedouin, named jabal, possessed a mare of great celebrity. hassad pacha, then governor of damascus, wished to buy the animal, and repeatedly made the owner the most liberal offers, which jabal steadily refused. the pacha then had recourse to threats, but with no better success. at length, one gafar, a bedouin of another tribe, presented himself to the pacha, and asked what he would give the man who should make him master of jabal's mare? "i will fill his horse's nose-bag with gold," replied hassad. the result of this interview having gone abroad; jabal became more watchful than ever, and always secured his mare at night with an iron chain, one end of which was fastened to her hind fetlock, whilst the other, after passing through the tent cloth, was attached to a picket driven in the ground under the felt that served himself and wife for a bed. but one midnight, gafar crept silently into the tent, and succeeded in loosening the chain. just before starting off with his prize, he caught up jabal's lance, and poking him with the butt end, cried out: "i am gafar! i have stolen your noble mare, and will give you notice in time." this warning was in accordance with the customs of the desert; for to rob a hostile tribe is considered an honorable exploit, and the man who accomplishes it is desirous of all the glory that may flow from the deed. poor jabal, when he heard the words, rushed out of the tent and gave the alarm, then mounting his brother's mare, accompanied by some of his tribe, he pursued the robber for four hours. the brother's mare was of the same stock as jabal's but was not equal to her; nevertheless, he outstripped those of all the other pursuers, and was even on the point of overtaking the robber, when jabal shouted to him: "pinch her right ear and give her a touch of the heel." gafar did so, and away went the mare like lightning, speedily rendering further pursuit hopeless. the _pinch in the ear_ and the _touch with the heel_ were the secret signs by which jabal had been used to urge his mare to her utmost speed. jabal's companions were amazed and indignant at his strange conduct. "o thou father of a jackass!" they cried, "thou hast helped the thief to rob thee of thy jewel." but he silenced their upbraidings by saying: "i would rather lose her than sully her reputation. would you have me suffer it to be said among the tribes that another mare had proved fleeter than mine? i have at least this comfort left me, that i can say she never met with her match." different countries have their different modes of horsemanship, but amongst all of them its first practice was carried on in but a rude and indifferent way, being hardly a stepping stone to the comfort and delight gained from the use of the horse at the present day. the polished greeks as well as the ruder nations of northern africa, for a long while rode without either saddle or bridle, guiding their horses, with the voice or the hand, or with a light switch with which they touched the animal on the side of the face to make him turn in the opposite direction. they urged him forward by a touch of the heel, and stopped him by catching him by the muzzle. bridles and bits were at length introduced, but many centuries elapsed before anything that could be called a saddle was used. instead of these, cloths, single or padded, and skins of wild beasts, often richly adorned, were placed beneath the rider, but always without stirrups; and it is given as an extraordinary fact, that the romans even in the times when luxury was carried to excess amongst them, never desired so simple an expedient for assisting the horseman to mount, to lessen his fatigue and aid him in sitting more securely in his saddle. ancient sculptors prove that the horsemen of almost every country were accustomed to mount their horses from the right side of the animal, that they might the better grasp the mane, which hangs on that side, a practice universally changed in modern times. the ancients generally leaped on their horse's backs, though they sometimes carried a spear, with a loop or projection about two feet from the bottom which served them as a step. in greece and rome, the local magistracy were bound to see that blocks for mounting (what the scotch call _loupin_-on-stanes) were placed along the road at convenient distances. the great, however, thought it more dignified to mount their horses by stepping on the bent backs of their servants or slaves, and many who could not command such costly help used to carry a light ladder about with them. the first distinct notice that we have of the use of the saddle occurs in the edict of the emperor theodosias, (a.d. 385) from which we also learn that it was usual for those who hired post-horses, to provide their own saddle, and that the saddle should not weigh more than sixty pounds, a cumbrous contrivance, more like the howdahs placed on the backs of elephants than the light and elegant saddle of modern times. side-saddles for ladies are an invention of comparatively recent date. the first seen in england was made for anne of bohemia, wife of richard the second, and was probably more like a pillion than the side-saddle of the present day. a pillion is a sort of a very low-backed arm-chair, and was fastened on the horse's croup, behind the saddle, on which a man rode who had all the care of managing the horse, while the lady sat at her ease, supporting herself by grasping a belt which he wore, or passing her arm around his body, if the _gentleman was not too ticklish_. but the mexicans manage these things with more gallantry than the ancients did. the "pisanna," or country lady, we are told is often seen mounted before her "cavalera," who take the more natural position of being seated behind his fair one, supporting her by throwing his arm around her waist, (a very appropriate support if the bent position of the arm does not cause an occasional contraction of the muscles.) these two positions may justly be considered as the first steps taken by the ladies towards their improved and elegant mode of riding at the present day. at an early period when the diversion of hawking was prevalent, they dressed themselves in the costume of the knight, and rode astride. horses were in general use for many centuries before anything like a protection for the hoof was thought of, and it was introduced, at first, as a matter of course, on a very simple scale. the first foot defense, it is said, which was given to the horse, was on the same principle as that worn by man, which was a sort of sandal, made of leather and tied to the horse's foot, by means of straps or strings. and finally plates of metal were fastened to the horse's feet by the same simple means. here again, as in the case of the sturrupless saddle, when we reflect that men should, for nearly a thousand years, have gone on fastening plates of metal under horses' hoofs by the clumsy means of straps and strings, without its ever occurring to them to try so simple an improvement as nails, we have another remarkable demonstration of the slow steps by which horsemanship has reached its present state. in the forgoing remarks i have taken the liberty of extracting several facts from a valuable little work by rolla springfield. with this short comment on the rise and progress of horsemanship, from its commencement up to the present time, i will proceed to give you the principles of a new theory of taming wild horses, which is the result of many experiments and a thorough investigation and trial of the different methods of horsemanship now in use. the three fundamental principles of my theory founded on the leading characteristics of the horse. first.--that he is so constituted by nature that he will not offer resistance to any demand made of him which he fully comprehends, if made in a way consistent with the laws of his nature. second.--that he has no consciousness of his strength beyond his experience, and can be handled according to our will, without force. third.--that we can, in compliance with the laws of his nature by which he examines all things new to him, take any object, however frightful, around, over or on him, that does not inflict pain, without causing him to fear. to take these assertions in order, i will first give you some of the reasons why i think he is naturally obedient, and will not offer resistance to anything fully comprehended. the horse, though possessed of some faculties superior to man's being deficient in reasoning powers, has no knowledge of right or wrong, of free will and independent government, and knows not of any imposition practiced upon him, however unreasonable these impositions may be. consequently, he cannot come to any decision what he should or should not do, because he has not the reasoning faculties of man to argue the justice of the thing demanded of him. if he had, taking into consideration his superior strength, he would be useless to man as a servant. give him _mind_ in proportion to his strength, and he will demand of us the green fields for an inheritance, where he will roam at leisure, denying the right of servitude at all. god has wisely formed his nature so that it can be operated upon by the knowledge of man according to the dictates of his will, and he might well be termed an unconscious, submissive servant. this truth we can see verified in every day's experience by the abuses practiced upon him. any one who chooses to be so cruel, can mount the noble steed and run him 'till he drops with fatigue, or, as is often the case with more spirited, fall dead with the rider. if he had the power to reason, would he not vault and pitch his rider, rather than suffer him to run him to death? or would he condescend to carry at all the vain imposter, who, with but equal intellect, was trying to impose on his equal rights and equally independent spirit? but happily for us, he has no consciousness of imposition, no thought of disobedience except by impulse caused by the violation of the law of nature. consequently when disobedient it is the fault of man. then, we can but come to the conclusion, that if a horse is not taken in a way at variance with the law of his nature, he will do anything that he fully comprehends without making any offer of resistance. _second._ the fact of the horse being unconscious of the amount of his strength, can be proven to the satisfaction of any one. for instance, such remarks as these are common, and perhaps familiar to your recollection. one person says to another, "if that wild horse there was conscious of the amount of his strength, his owner could have no business with him in that vehicle; such light reins and harness, too; if he knew he could snap them asunder in a minute and be as free as the air we breathe;" and, "that horse yonder that is pawing and fretting to follow the company that is fast leaving him, if he knew his strength he would not remain long fastened to that hitching post so much against his will, by a strap that would no more resist his powerful weight and strength, than a cotton thread would bind a strong man." yet these facts made common by every day occurrence, are not thought of as anything wonderful. like the ignorant man who looks at the different phases of the moon, you look at these things as he looks at her different changes, without troubling your mind with the question, "why are these things so?" what would be the condition of the world if all our minds lay dormant? if men did not think, reason and act, our undisturbed, slumbering intellects would not excel the imbecility of the brute; we would live in chaos, hardly aware of our existence. and yet with all our activity of mind, we daily pass by unobserved that which would be wonderful if philosophised and reasoned upon, and with the same inconsistency wonder at that which a little consideration, reason and philosophy would be but a simple affair. _thirdly._ he will allow any object, however frightful in appearance, to come around, over or on him, that does not inflict pain. we know from a natural course of reasoning, that there has never been an effected without a cause, and we infer from this, that there can be no action, either in animate or inanimate matter, without there first being some cause to produce it. and from this self-evident fact we know that there is some cause for every impulse or movement of either mind or matter, and that this law governs every action or movement of the animal kingdom. then, according to this theory, there must be some cause before fear can exist; and, if fear exists from the effect of imagination, and not from the infliction of real pain, it can be removed by complying with those laws of nature by which the horse examines an object, and determines upon its innocence or harm. a log or stump by the road-side may be, in the imagination of the horse, some great beast about to pounce upon him; but after you take him up to it and let him stand by it a little while, and touch it with his nose, and go through his process of examination, he will not care any thing more about it. and the same principle and process will have the same effect with any other object, however frightful in appearance, in which there is no harm. take a boy that has been frightened by a false-face or any other object that he could not comprehend at once; but let him take that face or object in his hands and examine it, and he will not care anything more about it. this is a demonstration of the same principle. with this introduction to the principles of my theory, i shall next attempt to teach you how to put it into practice, and whatever instructions may follow, you can rely on as having been proven practical by my own experiments. and knowing from experience just what obstacles i have met with in handling bad horses, i shall try to anticipate them for you, and assist you in surmounting them, by commencing with the first steps taken with the colt, and accompanying you through the whole task of breaking. how to succeed in getting the colt from pasture. go to the pasture and walk around the whole herd quietly, and at such a distance as not to cause them to scare and run. then approach them very slowly, and if they stick up their heads and seem to be frightened, hold on until they become quiet, so as not to make them run before you are close enough to drive them in the direction you want to go. and when you begin to drive, do not flourish your arms or hollow, but gently follow them off leaving the direction free for them that you wish them to take. thus taking advantage of their ignorance, you will be able to get them in the pound as easily as the hunter drives the quails into his net. for, if they have always run into the pasture uncared for, (as many horses do in prairie countries and on large plantations,) there is no reason why they should not be as wild as the sportsman's birds and require the same gentle treatment, if you want to get them without trouble; for the horse in his natural state is as wild as any of the undomesticated animals, though more easily tamed than most of them. how to stable a colt without trouble. the next step will be, to get the horse into a stable or shed. this should be done as quietly as possible, so as not to excite any suspicion in the horse of any danger befalling him. the best way to do this, is to lead a gentle horse into the stable first and hitch him, then quietly walk around the colt and let him go in of his own accord. it is almost impossible to get men, who have never practiced on this principle, to go slow and considerate enough about it. they do not know that in handling a wild horse, above all other things, is that good old adage true, that "haste makes waste;" that is, waste of time, for the gain of trouble and perplexity. one wrong move may frighten your horse, and make him think it is necessary to escape at all hazards for the safety of his life, and thus make two hours work of a ten minutes job; and this would be all your own fault, and entirely unnecessary; for he will not run unless you run after him, and that would not be good policy, unless you knew that you could outrun him; or you will have to let him stop of his own accord after all. but he will not try to break away, unless you attempt to force him into measures. if he does not see the way at once, and is a little fretful about going in, do not undertake to drive him, but give him a little less room outside, by gently closing in around him. do not raise your arms, but let them hang at your side; for you might as well raise a club. the horse has never studied anatomy, and does not know but they will unhinge themselves and fly at him. it he attempts to turn back, walk before him, but do not run; and if he gets past you, encircle him again in the same quiet manner, and he will soon find that you are not going to hurt him; and you can soon walk so close around him that he will go into the stable for more room, and to get farther from you. as soon as he is in, remove the quiet horse and shut the door. this will be his first notion of confinement--not knowing how to get in such a place, nor how to get out of it. that he may take it as quietly as possible, see that the shed is entirely free from dogs, chickens, or anything that would annoy him; then give him a few ears of corn, and let him remain alone fifteen or twenty minutes, until he has examined his apartment, and has become reconciled to his confinement. time to reflect. and now, while your horse is eating those few ears of corn, is the proper time to see that your halter is ready and all right, and to reflect on the best mode of operations; for, in the horsebreaking, it is highly important that you should be governed by some system. and you should know before you attempt to do anything, just what you are going to do, and how you are going to do it. and, if you are experienced in the art of taming wild horses, you ought to be able to tell within a few minutes the length of time it would take you to halter the colt, and learn him to lead. the kind of halter. always use a leather halter, and be sure to have it made so that it will not draw tight around his nose if he pulls on it. it should be of the right size to fit his head easily and nicely; so that the nose band will not be too tight or too low. never put a rope halter on an unbroken colt under any circumstances whatever. they have caused more horses to hurt or kill themselves, than would pay for twice the cost of all the leather halters that have ever been needed for the purpose of haltering colts. it is almost impossible to break a colt that is very wild with a rope halter, without having him pull, rear and throw himself, and thus endanger his life; and i will tell you why. it is just as natural for a horse to try to get his head out of anything that hurts it, or feels unpleasant, as it would be for you to try to get your hand out of a fire. the cords of the rope are hard and cutting; this makes him raise his head and draw on it, and as soon as he pulls, the slip noose (the way rope halters are always made) tightens, and pinches his nose, and then he will struggle for life, until, perchance, he throws himself; and who would have his horse throw himself, and run the risk of breaking his neck, rather than pay the price of a leather halter. but this is not the worst. a horse that has once pulled on his halter, can never be as well broke as one that has never pulled at all. remarks on the horse. but before we attempt to do anything more with the colt, i will give you some of the characteristics of his nature, that you may better understand his motions. every one that has ever paid any attention to the horse, has noticed his natural inclination to smell of everything which to him looks new and frightful. this is their strange mode of examining everything. and, when they are frightened at anything, though they look at it sharply, they seem to have no confidence in this optical examination alone, but must touch it with the nose before they are entirely satisfied; and, as soon as this is done, all is right. experiments with the robe. if you want to satisfy yourself of this characteristic of the horse, and learn something of importance concerning the peculiarities of his nature, etc., turn him into the barn-yard, or a large stable will do, and then gather up something that you know will frighten him; a red blanket, buffalo robe, or something of that kind. hold it up so that he can see it; he will stick up his head and snort. then throw it down somewhere in the center of the lot or barn, and walk off to one side. watch his motions, and study his nature. if he is frightened at the object, he will not rest until he has touched it with his nose. you will see him begin to walk around the robe and snort, all the time getting a little closer, as if drawn up by some magic spell, until he finally gets within reach of it. he will then very cautiously stretch out his neck as far as he can reach, merely touching it with his nose, as though he thought it was ready to fly at him. but after he has repeated these touches a few times, for the first (though he has been looking at it all the time) he seems to have an idea what it is. but now he has found, by the sense of feeling, that it is nothing that will do him any harm, and he is ready to play with it. and if you watch him closely, you will see him take hold of it with his teeth, and raise it up and pull at it. and in a few minutes you can see that he has not that same wild look about his eye, but stands like a horse biting at some familiar stump. yet the horse is never well satisfied when he is about anything that has frightened him, as when he is standing with his nose to it. and, in nine cases out of ten, you will see some of that same wild look about him again, as he turns to walk from it. and you will, probably, see him looking back very suspiciously as he walks away, as though he thought it might come after him yet. and, in all probability, he will have to go back and make another examination before he is satisfied. but he will familiarize himself with it, and, if he should run in that lot a few days, the robe that frightened him so much at first, will be no more to him than a familiar stump. suppositions on the sense of smelling. we might very naturally suppose, from the fact of the horse's applying his nose to every thing new to him, that he always does so for the purpose of smelling these objects. but i believe that it is as much or more for the purpose of feeling; and that he makes use of his nose or muzzle, (as it is sometimes called.) as we would of our hands; because it is the only organ by which he can touch or feel anything with much susceptibility. i believe that he invariably makes use of the four senses, seeing, hearing, smelling and feeling, in all of his examinations, of which the sense of feeling is, perhaps, the most important. and i think that in the experiment with the robe, his gradual approach and final touch with his nose was as much for the purpose of feeling, as anything else, his sense of smell being so keen, that it would not be necessary for him to touch his nose against anything in order to get the proper scent; for it is said that a horse can smell a man the distance of a mile. and, if the scent of the robe was all that was necessary, he could get that several rods off. but, we know from experience, that if a horse sees and smells a robe a short distance from him, he is very much frightened, (unless he is used to it,) until he touches or feels it with his nose; which is a positive proof that feeling is the controlling sense in this case. prevailing opinion of horsemen. it is a prevailing opinion among horsemen generally, that the sense of smell is the governing sense of the horse. and faucher, as well as others, have, with that view, got up receipts of strong smelling oils, etc., to tame the horse, sometimes using the chesnut of his leg, which they dry, grind into powder and blow into his nostrils. sometimes using the oil of rhodium, organnnum, etc.; that are noted for their strong smell. and sometimes they scent the hands with the sweat from under the arm, or blow their breath into his nostrils, etc., etc. all of which, as far as the scent goes have no effect whatever in gentling the horse, or conveying any idea to his mind; though the works that accompany these efforts--handling him, touching him about the nose and head, and patting him, as they direct you should, after administering the articles, may have a very great effect, which they mistake to be the effect of the ingredients used. and faucher, in his work entitled, "the arabian art of taming horses," page 17, tells us how to accustom a horse to a robe, by administering certain articles to his nose; and goes on to say, that these articles must first be applied to the horse's nose before you attempt to break him, in order to operate successfully. now, reader, can you, or any one else, give one single reason how scent can convey any idea to the horse's mind of what we want him to do? if not, then of course strong scents of any kind are of no account in taming the unbroken horse. for every thing that we get him to do of his own accord, without force, must be accomplished by some means of conveying our ideas to his mind. i say to my horse "go 'long" and he goes; "ho!" and he stops: because these two words, of which he has learned the meaning by the tap of the whip, and the pull of the rein that first accompanied them, convey the two ideas to his mind of go and stop. faucher, or no one else, can ever learn the horse a single thing by the means of a scent alone. how long do you suppose a horse would have to stand and smell of a bottle of oil before he would learn to bend his knee and make a bow at your bidding, "go yonder and bring your hat," or "come here and lay down?" thus you see the absurdity of trying to break or tame the horse by the means of receipts for articles to smell of, or medicine to give him, of any kind whatever. the only science that has ever existed in the world, relative to the breaking of horses, that has been of any account, is that true method which takes them in their native state, and improves their intelligence. powel's system of approaching the colt. but, before we go further, i will give you willis j. powel's system of approaching a wild colt, as given by him in a work published in europe, about the year 1811, on the "art of taming wild horses." he says, "a horse is gentled by my secret, in from two to sixteen hours." the time i have most commonly employed has been from four to six hours. he goes on to say: "cause your horse to be put in a small yard, stable, or room. if in a stable or room, it ought to be large in order to give him some exercise with the halter before you lead him out. if the horse belong to that class which appears only to fear man, you must introduce yourself gently into the stable, room, or yard, where the horse is. he will naturally run from you, and frequently turn his head from you; but you must walk about extremely slow and softly, so that he can see you whenever he turns his head towards you, which he never fails to do in a short time, say in a quarter of an hour. i never knew one to be much longer without turning towards me. "at the very moment he turns his head, hold out your left hand towards him, and stand perfectly still, keeping your eyes upon the horse, watching his motions if he makes any. if the horse does not stir for ten or fifteen minutes, advance as slowly as possible, and without making the least noise, always holding out your left hand, without any other ingredient in it than that what nature put in it." he says, "i have made use of certain, ingredients before people, such as the sweat under my arm, etc., to disguise the real secret, and many believed that the docility to which the horse arrived in so short a time, was owing to these ingredients; but you see from this explanation that they were of no use whatever. the implicit faith placed in these ingredients, though innocent of themselves, becomes 'faith without works.' and thus men remained always in doubt concerning this secret. if the horse makes the least motion when you advance toward him, stop, and remain perfectly still until he is quiet. remain a few moments in this condition, and then advance again in the same slow and imperceptible manner. take notice: if the horse stirs, stop without changing your position. it is very uncommon for the horse to stir more than once after you begin to advance, yet there are exceptions. he generally keeps his eyes steadfast on you, until you get near enough to touch him on the forehead. when you are thus near to him, raise slowly, and by degrees, your hand, and let it come in contact with that part just above the nostrils as lightly as possible. if the horse flinches, (as many will,) repeat with great rapidity these light strokes upon the forehead, going a little further up towards his ears by degrees, and descending with the same rapidity until he will let you handle his forehead all over. now let the strokes be repeated with more force over all his forehead, descending by lighter strokes to each side of his head, until you can handle that part with equal facility. then touch in the same light manner, making your hands and fingers play around the lower part of the horse's ears, coming down now and then to his forehead, which may be looked upon as the helm that governs all the rest. "having succeeded in handling his ears, advance towards the neck, with the same precautions, and in the same manner; observing always to augment the force of the strokes whenever the horse will permit it. perform the same on both sides of the neck, until he lets you take it in your arms without flinching. "proceed in the same progressive manner to the sides, and then to the back of the horse. every time the horse shows any nervousness return immediately to the forehead as the true standard, patting him with your hands, and from thence rapidly to where you had already arrived, always gaining ground a considerable distance farther on every time this happens. the head, ears, neck and body being thus gentled, proceed from the back to the root of the tail. "this must be managed with dexterity, as a horse is never to be depended on that is skittish about the tail. let your hand fall lightly and rapidly on that part next to the body a minute or two, and then you will begin to give it a slight pull upwards every quarter of a minute. at the same time you continue this handling of him, augment the force of the strokes, as well as the raising of the tail, until you can raise it and handle it with the greatest ease, which commonly happens in a quarter of an hour in most horses; in others almost immediately, and in some much longer. it now remains to handle all his legs. from the tail come back again to the head, handle it well, as likewise the ears, breast, neck, etc., speaking now and then to the horse. begin by degrees to descend to the legs, always ascending and descending, gaining ground every time you descend until you get to his feet. "talk to the horse in latin, greek, french, english, or spanish, or in any other language you please; but let him hear the sound of your voice, which at the beginning of the operation is not quite so necessary, but which i have always done in making him lift up his feet. hold up your foot--'live la pied'--'alza el pie'--'aron ton poda,' etc., at the same time lift his foot with your hand. he soon becomes familiar with the sounds, and will hold his foot up at command. then proceed to the hind feet and go on in the same manner, and in a short time the horse will let you lift them and even take them up in your arms. "all this operation is no magnetism, no galvanism; it is merely taking away the fear a horse generally has of a man, and familiarizing the animal with his master; as the horse doubtless experiences a certain pleasure from this handling, he will soon become gentle under it, and show a very marked attachment to his keeper." remarks on powel's treatment how to govern horses of any kind. these instructions are very good, but not quite sufficient for horses of all kinds, and for haltering and leading the colt; but i have inserted it here, because it gives some of the true philosophy of approaching the horse, and of establishing confidence between man and horse. he speaks only of the kind that fear man. to those who understand the philosophy of horsemanship, these are the easiest trained; for when we have a horse that is wild and lively, we can train him to our will in a very short time; for they are generally quick to learn, and always ready to obey. but there is another kind that are of a stubborn or vicious disposition, and, although they are not wild, and do not require taming, in the sense it is generally understood, they are just as ignorant as a wild horse, if not more so, and need to be learned just as much; and in order to have them obey quickly, it is very necessary that they should be made to fear their masters; for, in order to obtain perfect obedience from any horse, we must first have him fear us, for our motto is _fear, love, and obey_; and we must have the fulfilment of the first two before we can expect the latter, and it is by our philosophy of creating fear, love and confidence, that we govern to our will every kind of a horse whatever. then, in order to take horses as we find them, or all kinds, and to train them to our likings, we will always take with us, when we go into a stable to train a colt, a long switch whip, (whale-bone buggy whips is the best,) with a good silk cracker, so as to cut keen and make a sharp report, which, if handled with dexterity, and rightly applied, accompanied with a sharp, fierce word, will be sufficient to enliven the spirits of any horse. with this whip in your right hand, with the lash pointing backward, enter the stable alone. it is a great disadvantage in training a horse, to have any one in the stable with you; you should be entirely alone, so as not to have nothing but yourself to attract his attention. if he is wild you will soon see him in the opposite side of the stable from you; and now is the time to use a little judgement. i would not want for myself, more than half or three-quarters of an hour to handle any kind of a colt, and have him running about in the stable after me; though i would advise a new beginner to take more time, and not to be in too much of a hurry. if you have but one colt to gentle, and are not particular about the length of time you spend, and have not had any experience in handling colts, i would advise you to take mr. powel's method at first, till you gentle him, which he says takes from two to six hours. but, as i want to accomplish the same, and what is much more, learn the horse to lead in less than one hour, i shall give you a much quicker process of accomplishing the same end. accordingly, when you have entered the stable, stand still and let your horse look at you a minute or two, and as soon as he is settled in one place, approach him slowly, with both arms stationary, your right hanging by your side, holding the whip as directed, and the left bent at the elbow, with your hand projecting. as you approach him, go not too much towards his head or croop, so as not to make him move either forward or backward, thus keeping your horse stationary, if he does move a little forward or backward, step a little to the right or left very cautiously; this will keep him in one place, as you get very near him, draw a little to his shoulder, and stop a few seconds. if you are in his reach he will turn his head and smell at your hand, not that he has any preference for your hand, but because that it is projecting, and is the nearest portion of your body to the horse. this all colts will do, and they will smell of your naked hand just as quick as they will of any thing that you can put in it, and with just as good an effect, however much some men have preached the doctrine of taming horses by giving them the scent articles from the hand. i have already proved that to be a mistake. as soon as he touches his nose to your hand, caress him as before directed, always using a very light, soft hand, merely touching the horse, all ways rubbing the way the hair lays, so that your hand will pass along as smoothly as possible. as you stand by his side you may find it more convenient to rub his neck or the side of his head, which will answer the same purpose, as rubbing his forehead. favor every inclination of the horse to smell or touch you with his nose. always follow each touch or communication of this kind with the most tender and affectionate caresses, accompanied with a kind look, and pleasant word of some sort, such as: ho! my little boy, ho! my little boy, pretty boy, nice lady! or something of that kind, constantly repeating the same words, with the same kind, steady tone of voice; for the horse soon learns to read the expression of the face and voice, and will know as well when fear, love or anger, prevails as you know your own feelings; two of which, _fear and anger_, a good horseman _should never feel_. how to proceed if your horse is of a stubborn disposition. if your horse, instead of being wild, seems to be of a stubborn or _mulish_ disposition; if he lays back his ears as you approach him, or turns his heels to kick you, he has not that regard or fear of man that he should have, to enable you to handle him quickly and easily; and it might be well to give him a few sharp cuts with the whip, about the legs, pretty close to the body. it will crack keen as it plies around his legs, and the crack of the whip will affect him as much as the stroke; besides one sharp cut about his legs will affect him more than two or three over his back, the skin on the inner part of his legs or about his flank being thinner, more tender than on his back. but do not whip him much, just enough to scare him, it is not because we want to hurt the horse that we whip him, we only do it to scare that bad disposition out of him. but whatever you do, do quickly, sharply and with a good deal of fire, but always without anger. if you are going to scare him at all you must do it at once. never go into a pitch battle with your horse, and whip him until he is mad and will fight you; you had better not touch him at all, for you will establish, instead of fear and regard, feelings of resentment, hatred and ill-will. it will do him no good but an injury, to strike a blow, unless you can scare him; but if you succeed in scaring him, you can whip him without making him mad; for fear and anger never exist together in the horse, and as soon as one is visible, you will find that the other has disappeared. as soon as you have frightened him so that he will stand up straight and pay some attention to you, approach him again and caress him a good deal more than you whipped him, then you will excite the two controlling passions of his nature, love and fear, and then he will fear and love you too, and as soon as he learns what to do will quickly obey. how to halter and lead the colt. as soon as you have gentled the colt a little, take the halter in your left hand and approach him as before, and on the same side that you have gentled him. if he is very timid about your approaching closely to him, you can get up to him quicker by making the whip a part of your arm, and reaching out very gently with the but end of it, rubbing him lightly on the neck, all the time getting a little closer, shortening the whip by taking it up in your hand, until you finally get close enough to put your hands on him. if he is inclined to hold his head from you, put the end of the halter strap around his neck, drop your whip, and draw very gently; he will let his neck give, and you can pull his head to you. then take hold of that part of the halter, which buckles over the top of his head, and pass the long side, or that part which goes into the buckle, under his neck, grasping it on the opposite side with your right hand, letting the first strap loose--the latter will be sufficient to hold his head to you. lower the halter a little, just enough to get his nose into that part which goes around it, then raise it somewhat, and fasten the top buckle, and you will have it all right. the first time you halter a colt you should stand on the left side, pretty well back to his shoulder only taking hold of that part of the halter that goes around his neck, then with your hands about his neck you can hold his head to you, and raise the halter on it without making him dodge by putting your hands about his nose. you should have a long rope or strap ready, and as soon as you have the halter on, attach this to it, so that you can let him walk the length of the stable without letting go of the strap, or without making him pull on the halter, for if you only let him feel the weight of your hand on the halter, and give him rope when he runs from you, he will never rear, pull, or throw himself, yet you will be holding him all the time, and doing more towards gentling him, than if you had the power to snub him right up, and hold him to one spot; because, he does not know any thing about his strength, and if you don't do any thing to make him pull, he will never know that he can. in a few minutes you can begin to control him with the halter, then shorten the distance between yourself and the horse, by taking up the strap in your hand. as soon as he will allow you to hold him by a tolerably short strap, and step up to him without flying back, you can begin to give him some idea about leading. but to do this, do not go before and attempt to pull him after you, but commence by pulling him very quietly to one side. he has nothing to brace either side of his neck, and will soon yield to a steady, gradual pull of the halter; and as soon as you have pulled him a step or two to one side, step up to him and caress him, and then pull him again, repeating this operation until you can pull him around in every direction, and walk about the stable with him, which you can do in a few minutes, for he will soon think when you have made him step to the right or left a few times, that he is compelled to follow the pull of the halter, not knowing that he has the power to resist your pulling; besides, you have handled him so gently, that he is not afraid of you, and you always caress him when he comes up to you, and he likes that, and would just as leave follow you as not. and after he has had a few lessons of that kind, if you turn him out in a lot he will come up to you every opportunity he gets. you should lead him about in the stable some time before you take him out, opening the door, so that he can see out, leading him up to it and back again, and past it. see that there is nothing on the outside to make him jump, when you take him out, and as you go out with him, try to make him go very slowly, catching hold of the halter close to the jaw, with your left hand, while the right is resting on the top of the neck, holding to his mane. after you are out with him a little while, you can lead him about as you please. don't let any second person come up to you when you first take him out; a stranger taking hold of the halter would frighten him, and make him run. there should not even be any one standing near him to attract his attention, or scare him. if you are alone, and manage him right, it will not require any more force to lead or hold him than it would to manage a broke horse. how to lead a colt by the side of a broken horse. if you should want to lead your colt by the side of another horse, as is often the case, i would advise you to take your horse into the stable, attach a second strap to the colt's halter, and lead your horse up alongside of him. then get on the broke horse and take one strap around his breast, under his martingale, (if he has any on,) holding it in your left hand. this will prevent the colt from getting back too far; besides, you will have more power to hold him, with the strap pulling against the horse's breast. the other strap take up in your right hand to prevent him from running ahead; then turn him about a few times in the stable, and if the door is wide enough, ride out with him in that position; if not, take the broke horse out first, and stand his breast up against the door, then lead the colt to the same spot, and take the straps as before directed, one on each side of his neck, then let some one start the colt out, and as he comes out, turn your horse to the left, and you will have them all right. this is the best way to lead a colt; you can manage any kind of a colt in this way, without any trouble; for, if he tries to run ahead, or pull back, the two straps will bring the horses facing each other, so that you can easily follow up his movements without doing much holding, and as soon as he stops running backward you are right with him, and all ready to go ahead. and if he gets stubborn and does not want to go, you can remove all his stubbornness by riding your horse against his neck, thus compelling him to turn to the right, and as soon as you have turned him about a few times, he will be willing to go along. the next thing, after you are through leading him, will be to take him into a stable, and hitch him in such a way as not to have him pull on the halter, and as they are often troublesome to get into a stable the first few times, i will give you some instructions about getting him in. how to lead a colt into the stable and hitch him without having him pull on the halter. you should lead the broke horse into the stable first, and get the colt, if you can, to follow in after him. if he refuses to go, step up to him, taking a little stick or switch in your right hand; then take hold of the halter close to his head with your left hand, at the same time reaching over his back with your right arm so that you can tap him on the opposite side with your switch; bring him up facing the door, tap him lightly with your switch, reaching as far back with it as you can. this tapping, by being pretty well back, and on the opposite side, will drive him ahead, and keep him close to you, then by giving him the right direction with your left hand you can walk into the stable with him. i have walked colts into the stable this way, in less than a minute, after men had worked at them half an hour, trying to pull them in. if you cannot walk him it at once this way, turn him about and walk him round in every direction, until you can get him up to the door without pulling at him. then let him stand a few minutes, keeping his head in the right direction with the halter, and he will walk in, in less than ten minutes. never attempt to pull the colt into the stable; that would make him think at once that it was a dangerous place, and if he was not afraid of it before, he would be then. besides we don't want him to know anything about pulling on the halter. colts are often hurt, and sometimes killed, by trying to force them into the stable; and those who attempt to do it in that way, go into an up-hill business, when a plain smooth road is before them. if you want to hitch your colt, put him in a tolerably wide stall which should not be too long, and should be connected by a bar or something of that kind to the partition behind it; so that, after the colt is in he cannot get far enough back to take a straight, backward pull on the halter; then by hitching him in the center of the stall, it would be impossible for him to pull on the halter, the partition behind preventing him from going back, and the halter in the center checking him every time he turns to the left or right. in a state of this kind you can break every horse to stand hitched by a light strap, any where, without his ever knowing any thing about pulling. but if you have broke your horse to lead, and have learned him the use of the halter (which you should always do before you hitch him to any thing), you can hitch him in any kind of a stall, and give him something to eat to keep him up to his place for a few minutes at first and there is not one colt in fifty that will pull on his halter. the kind of bit and how to accustom a horse to it. you should use a large, smooth, snaffle bit, so as not to hurt his mouth, with a bar to each side, to prevent the bit from pulling through either way. this you should attach to the head-stall of your bridle and put it on your colt without any reins to it, and let him run loose in a large stable or shed, some time, until he becomes a little used to the bit, and will bear it without trying to get it out of his mouth. it would be well, if convenient, to repeat this several times before you do anything more with the colt; as soon as he will bear the bit, attach a single rein to it, without any martingale. you should also have a halter on your colt, or a bridle made after the fashion of a halter, with a strap to it, so that you can hold or lead him about without pulling on the bit much. he is now ready for the saddle. how to saddle a colt. any one man, who has this theory, can put a saddle on the wildest colt that ever grew, without any help, and without scaring him. the first thing will be to tie each stirrup strap into a loose knot to make them short, and prevent the stirrups from flying about and hitting him. then double up the skirts and take the saddle under your right arm, so as not to frighten him with it as you approach. when you get to him, rub him gently a few times with your hand, and then raise the saddle very slowly until he can see it, and smell, and feel it with his nose. then let the skirts loose, and rub it very gently against his neck the way the hair lays, letting him hear the rattle of the skirts as he feels them against him; each time getting a little farther backward, and finally slip it over his shoulders on his back. shake it a little with your hand, and in less than five minutes you can rattle it about over his back as much as you please, and pull it off and throw it on again, without his paying much attention to it. as soon as you have accustomed him to the saddle, fasten the girth. be careful how you do this. it often frightens a colt when he feels the girth binding him, and making the saddle fit tight on his back. you should bring up the girth very gently, and not draw it too tight at first, just enough to hold the saddle on. move him a little, and then girth it as tight as you choose, and he will not mind it. you should see that the pad of your saddle is all right before you put it on, and that there is nothing to make it hurt him, or feel unpleasant to his back. it should not have any loose straps on the back part of it to flap about and scare him. after you have saddled him in this way, take a switch in your right hand to tap him up with, and walk about in the stable a few times with your right arm over the saddle, taking hold of the reins on each side of his neck, with your right and left hands. thus marching him about in the stable until you learn him the use of the bridle, and can turn him about in any direction, and stop him by a gentle pull of the rein. always caress him, and loose the reins a little every time you stop him. you should always be alone, and have your colt in some tight stable or shed, the first time you ride him; the loft should be high so that you can sit on his back without endangering your head. you can learn him more in two hours time in a stable of this kind, than you could in two weeks in the common way of breaking colts, out in an open place. it you follow my course of treatment, you need not run any risk, or have any trouble in riding the worst kind of a horse. you take him a step at a time, until you get up a mutual confidence and trust between yourself and horse. first learn him to lead and stand hitched, next acquaint him with the saddle, and the use of the bit; and then all that remains, is to get on him without scaring him, and you can ride him as well as any horse. how to mount the colt. first gentle him well on both sides, about the saddle, and all over, until he will stand still without holding, and is not afraid to see you any where about him. as soon as you have him thus gentled, get a small block, about one foot or eighteen inches in height, and set it down by the side of him, about where you want to stand to mount him; step up on this, raising yourself very gently; horses notice every change of position very closely, and if you were to step up suddenly on the block, it would be very apt to scare him; but by raising yourself gradually on it, he will see you, without being frightened, in a position very near the same as when you are on his back. as soon as he will bear this without alarm, untie the stirrup strap next to you, and put your left foot into the stirrup, and stand square over it, holding your knee against the horse, and your toe out, so as to touch him under the shoulder with the toe of your boot. place your right hand on the front of the saddle and on the opposite side of you. taking hold of a portion of the mane and the reins as they hang loosely over his neck with your left hand; then gradually bear your weight on the stirrup, and on your right hand, until the horse feels your whole weight on the saddle; repeat this several times, each time raising yourself a little higher from the block, until he will allow you to raise your leg over his croop, and place yourself in the saddle. there are three great advantages in having a block to mount from. first, a sudden change of position is very apt to frighten a young horse that has never been handled; he will allow you to walk up to him, and stand by his side without scaring at you, because you have gentled him to that position, but if you get down on your hands and knees and crawl towards him, he will be very much frightened, and upon the same principle, he would frighten at your new position if you had the power to hold yourself over his back without touching him. then the first great advantage of the block is to gradually gentle him to that new position in which he will see you when you ride him. secondly, by the process of leaning your weight in the stirrups, and on your hand, you can gradually accustom him to your weight, so as not to frighten him by having him feel it all at once. and in the third place the block elevates you so that you will not have to make a spring in order to get on to the horse's back, but from it you can gradually raise yourself into the saddle. when you take these precautions, there is no horse so wild, but what you can mount him without making him jump. i have tried it on the worst horses that could be found, and have never failed in any case. when mounting, your horse should always stand without being held. a horse is never well broke when he has to be held with a tight rein while mounting; and a colt is never so safe to mount, as when you see that assurance of confidence, and absence of fear, which causes him to stand without holding. how to ride the colt. when you want him to start do not touch him on the side with your heel or do anything to frighten him and make him jump. but speak to him kindly, and if he does not start pull him a little to the left until he starts, and then let him walk off slowly with the reins loose. walk him around in the stable a few times until he gets used to the bit, and you can turn him about in every direction and stop him as you please. it would be well to get on and off a good many times until he gets perfectly used to it before you take him out of the stable. after you have trained him in this way, which should not take you more than one or two hours, you can ride him any where you choose without ever having him jump or make any effort to throw you. when you first take him out of the stable be very gentle with him, as he will feel a little more at liberty to jump or run, and be a little easier frightened than he was while in the stable. but after handling him so much in the stable he will be pretty well broke, and you will be able to manage him without trouble or danger. when you first mount him take a little the shortest hold on the left rein, so that if any thing frightens him you can prevent him jumping by pulling his head around to you. this operation of pulling a horse's head around against his side will prevent any horse from jumping ahead, rearing up, or running away. if he is stubborn and will not go you can make him move by pulling his head around to one side, when whipping would have no effect. and turning him around a few times will make him dizzy, and then by letting him have his head straight, and giving him a little touch with the whip, he will go along without any trouble. never use martingales on a colt when you first ride him; every movement of the hand should go right to the bit in the direction in which it is applied to the reins, without a martingale to change the direct of the force applied. you can guide the colt much better without them, and learn him the use of the bit in much less time. besides, martingales would prevent you from pulling his head around if he should try to jump. after your colt has been rode until he is gentle and well accustomed to the bit, you may find it an advantage if he carries his head too high, or his nose too far out, to put martingales on him. you should be careful not to ride your colt so far at first as to heat, worry or tire him. get off as soon as you see he is a little fatigued; gentle him and let him rest, this will make him kind to you and prevent him from getting stubborn or mad. the proper way to bit a colt. farmers often put bitting harness on a colt the first thing they do to him, buckling up the bitting as tight as they can draw it to make him carry his head high, and then turn him out in a lot to run a half day at a time. this is one of the worst punishments that they could inflict on the colt, and very injurious to a young horse that has been used to running in pasture with his head down. i have seen colts so injured in this way that they never got over it. a horse should be well accustomed to the bit before you put on the bitting harness, and when you first bit him you should only rein his head up to that point where he naturally holds it, let that be high or low; he will soon learn that he cannot lower his head, and that raising it a little will loosen the bit in his mouth. this will give him the idea of raising his head to loosen the bit, and then you can draw the bitting a little tighter every time you put it on, and he will still raise his head to loosen it; by this means you will gradually get his head and neck in the position you want him to carry it, and give him a nice and graceful carriage without hurting him, making him mad, or causing his mouth to get sore. if you put the bitting on very tight the first time, he cannot raise his head enough to loosen it, but will bear on it all the time, and paw, sweat and throw himself. many horses have been killed by falling backward with the bitting on, their heads being drawn up, strike the ground with the whole weight of the body. horses that have their heads drawn up tightly should not have the bitting on more than fifteen or twenty minutes at a time. how to drive a horse that is very wild, and has any vicious habit take up one fore foot and bend his knee till his hoof is bottom upwards, and merely touching his body, then slip a loop over his knee, and up until it comes above the pasture joint to keep it up, being careful to draw the loop together between the hoof and pasture joint with a second strap of some kind, to prevent the loop from slipping down and coming off. this will leave the horse standing on three legs; you can now handle him as you wish, for it is utterly impossible for him to kick in this position. there is something in this operation of taking up one foot that conquers a horse quicker and better than any thing else you can do to him. there is no process in the world equal to it to break a kicking horse, for several reasons. first, there is a principle of this kind in the nature of the horse; that by conquering one member you conquer to a great extent the whole horse. you have perhaps seen men operate upon this principle by sewing a horse's ears together to prevent him from kicking. i once saw a plan given in a newspaper to make a bad horse stand to be shod, which was to fasten down one ear. there were no reasons given why you should do so; but i tried it several times, and thought it had a good effect--though i would not recommend its use, especially stitching his ears together. the only benefit arising from this process is, that by disarranging his ears we draw his attention to them, and he is not so apt to resist the shoeing. by tying up one foot we operate on the same principle to a much better effect. when you first fasten up a horse's foot he will sometimes get very mad, and strike with his knee, and try every possible way to get it down; but he cannot do that, and will soon give it up. this will conquer him better than anything you could do, and without any possible danger of hurting himself or you either, for you can tie up his foot and sit down and look at him until he gives up. when you find that he is conquered, go to him, let down his foot, rub his leg with your hand, caress him and let him rest a little, then put it up again. repeat this a few times, always putting up the same foot, and he will soon learn to travel on three legs so that you can drive him some distance. as soon as he gets a little used to this way of traveling, put on your harness and hitch him to a sulky. if he is the worst kicking horse that ever raised a foot you need not be fearful of his doing any damage while he has one foot up, for he cannot kick, neither can he run fast enough to do any harm. and if he is the wildest horse that ever had harness on, and has run away every time he has been hitched, you can now hitch him in a sulky and drive him as you please. and if he wants to run you can let him have the lines, and the whip too, with perfect safety, for he cannot go but a slow gait on three legs, and will soon be tired and willing to stop; only hold him enough to guide him in the right direction, and he will soon be tired and willing to stop at the word. thus you will effectually cure him at once of any further notion of running off. kicking horses have always been the dread of every body; you always hear men say, when they speak about a bad horse, "i don't care what he does, so he don't kick." this new method is an effectual cure for this worst of all habits. there are plenty of ways by which you can hitch a kicking horse and force him to go, though he kicks all the time; but this don't have any good effect towards breaking him, for we know that horses kick because they are afraid of what is behind them, and when they kick against it and it hurts them they will only kick the harder, and this will hurt them still more and make them remember the scrape much longer, and make it still more difficult to persuade them to have any confidence in any thing dragging behind them ever after. but by this new method you can hitch them to a rattling sulky, plow, wagon, or anything else in its worst shape. they may be frightened at first, but cannot kick or do any thing to hurt themselves, and will soon find that you do not intend to hurt them, and then they will not care any thing more about it. you can then let down the leg and drive along gently without any farther trouble. by this new process a bad kicking horse can be learned to go gentle in harness in a few hours' time. on balking. horses know nothing about balking, only as they are brought into it by improper management, and when a horse balks in harness it is generally from some mismanagement, excitement, confusion, or from not knowing how to pull, but seldom from any unwillingness to perform all that he understands. high spirited, free going horses are the most subject to balking, and only so because drivers do not properly understand how to manage this kind. a free horse in a team may be so anxious to go that when he hears the word he will start with a jump, which will not move the load, but give him such a severe jerk on the shoulders that he will fly back and stop the other horse; the teamster will continue his driving without any cessation, and by the time he has the slow horse started again he will find that the free horse has made another jump, and again flew back, and now he has them both badly balked, and so confused that neither of them knows what is the matter, or how to start the load. next will come the slashing and cracking of the whip, and hallooing of the driver, till something is broken or he is through with his course of treatment. but what a mistake the driver commits by whipping his horse for this act. reason and common sense should teach him that the horse was willing and anxious to go, but did not know how to start the load. and should he whip him for that? if so, he should whip him again for not knowing how to talk. a man that wants to act with any rationality or reason should not fly into a passion, but should always think before he strikes. it takes a steady pressure against the collar to move a load, and you cannot expect him to act with a steady, determined purpose while you are whipping him. there is hardly one balking horse in five hundred that will pull true from whipping; it is only adding fuel to fire, and will make them more liable to balk another time. you always see horses that have been balked a few times, turn their heads and look back, as soon as they are a little frustrated. this is because they have been whipped and are afraid of what is behind them. this is an invariable rule with balked horses, just as much as it is for them to look around at their sides when they have the bots; in either case they are deserving of the same sympathy and the same kind, rational treatment. when your horse balks, or is a little excited, if he wants to start quickly, or looks around and don't want to go, there is something wrong, and needs kind he treatment immediately. caress him kindly, and if he don't understand at once what you want him to do he will not be so much excited as to jump and break things, and do everything wrong through fear. as long as you are calm and can keep down the excitement of the horse, there are ten chances to have him understand you, where there would not be one under harsh treatment, and then the little _flare up_ would not carry with it any unfavorable recollections, and he would soon forget all about it, and learn to pull true. almost every wrong act the horse commits is from mismanagement, fear or excitement; one harsh word will so excite a nervous horse as to increase his pulse ten beats in a minute. when we remember that we are dealing with dumb brutes, and reflect how difficult it must be for them to understand our motions, signs and language, we should never get out of patience with them because they don't understand us, or wonder at their doing things wrong. with all our intellect, if we were placed in the horse's situation, it would be difficult for us to understand the driving of some foreigner, of foreign ways and foreign language. we should always recollect that our ways and language are just as foreign and unknown to the horse as any language in the world is to us, and should try to practice what we could understand, were we the horse, endeavoring by some simple means to work on his understanding rather than on the different parts of his body. all balked horses can be started true and steady in a few minutes time; they are all willing to pull as soon as they know how, and i never yet found a balked horse that i could not teach him to start his load in fifteen, and often less than three minutes time. almost any team, when first balked, will start kindly, if you let them stand five or ten minutes, as though there was nothing wrong, and then speak to them with a steady voice, and turn them a little to the right or left, so as to get them both in motion before they feel the pinch of the load. but if you want to start a team that you are not driving yourself, that has been balked, fooled and whipped for some time, go to them and hang the lines on their hames, or fasten them to the wagon, so that they will be perfectly loose; make the driver and spectators (if there is any) stand off some distance to one side, so as not to attract the attention of the horses; unloose their checkreins, so that they can get their heads down, if they choose; let them stand a few minutes in this condition, until you can see that they are a little composed. while they are standing you should be about their heads, gentling them; it will make them a little more kind, and the spectators will think that you are doing something that they do not understand, and will not learn the secret. when you have them ready to start, stand before them, and as you seldom have but one balky horse in a team, get as near in front of him as you can, and if he is too fast for the other horse, let his nose come against your breast; this will keep him steady, for he will go slow rather than run on you; turn them gently to the right, without letting them pull on the traces, as far as the tongue will let them go; stop them with a kind word, gentle them a little, and then turn them back to the left, by the same process. you will have them under your control by this time, and as you turn them again to the right, steady them in the collar, and you can take them where you please. there is a quicker process that will generally start a balky horse, but not so sure. stand him a little ahead, so that his shoulders will be against the collar, and then take up one of his fore feet in your hand, and let the driver start them, and when the weight comes against his shoulders, he will try to step; then let him have his foot, and he will go right along. if you want to break a horse from balking that has long been in that habit, you ought to set apart a half day for that purpose. put him by the side of some steady horse; have check lines on them; tie up all the traces and straps, so that there will be nothing to excite them; do not rein them up, but let them have their heads loose. walk them about together for some time as slowly and lazily as possible; stop often, and go up to your balky horse and gentle him. do not take any whip about him, or do any thing to excite him, but keep him just as quiet as you can. he will soon learn to start off at the word, and stop whenever you tell him. as soon as he performs right, hitch him in an empty wagon; have it stand in a favorable position for starting. it would be well to shorten the stay chain behind the steady horse, so that if it is necessary he can take the weight of the wagon the first time you start them. do not drive but a few rods at first; watch your balky horse closely, and if you see that he is getting balky, stop him before he stops of his own accord, caress him a little, and start again. as soon as they go well, drive them over a small hill a few times, and then over a large one, occasionally adding a little load. this process will make any horse true to pull. to break a horse to harness. take him in a tight stable, as you did to ride him; take the harness and go through the same process that you did with the saddle, until you get him familiar with them, so that you can put them on him and rattle them about without his caring for them. as soon as he will bear this, put on the lines, caress him as you draw them over him, and drive him about in the stable till he will bear them over his hips. the _lines_ are a great aggravation to some colts, and often frighten them as much as if you were to raise a whip over them. as soon as he is familiar with the harness and line, take him out and put him by the side of a gentle horse, and go through the same process that you did with the balking horse. always use a bridle without blinds when you are breaking a horse to harness. how to hitch a horse in a sulky. lead him to and around it; let him look at it, touch it with his nose, and stand by it till he does not care for it; then pull the shafts a little to the left, and stand by your horse in front of the off wheel. let some one stand on the right side of the horse, and hold him by the bit, while you stand on the left side, facing the sulky. this will keep him straight. run your left hand back and let it rest on his hip, and lay hold of the shafts with your right, bringing them up very gently to the left hand, which still remains stationary. do not let anything but your arm touch his back, and as soon as you have the shafts square over him, let the person on the opposite side take hold of one of them and lower them very gently on the shaft bearers. be very slow and deliberate about hitching; the longer time you take, the better, as a general thing. when you have the shafts placed, shake them slightly, so that he will feel them against each side. as soon as he will bear them without scaring, fasten your braces, etc., and start him along very slowly. let one man lead the horse to keep him gentle, while the other gradually works back with the lines till he can get behind and drive him. after you have driven him in this way a short distance, you can get into the sulky, and all will go right. it is very important to have your horse go gently, when you first hitch him. after you have walked him awhile, there is not half so much danger of his scaring. men do very wrong to jump up behind a horse to drive him as soon as they have him hitched. there are too many things for him to comprehend all at once. the shafts, the lines, the harness, and the rattling of the sulky, all tend to scare him, and he must be made familiar with them by degrees. if your horse is very wild, i would advise you to put up one foot the first time you drive him. how to make a horse lie down. every thing that we want to learn the horse must be commenced in some way to give him an idea of what you want him to do, and then be repeated till he learns it perfectly. to make a horse lie down, bend his left fore leg, and slip a loop over it, so that he cannot get it down. then put a circingle around his body, and fasten one end of a long strap around the other fore leg, just above the hoof. place the other end under the circingle, so as to keep the strap in the right hand; stand on the left side of the horse, grasp the bit in your left hand, pull steadily on the strap with your right; bear against his shoulder till you cause him to move. as soon as he lifts his weight, your pulling will raise the other foot, and he will have to come on his knees. keep the strap tight in your hand, so that he cannot straighten his leg if he raises up. hold him in his position, and turn his head toward you; bear against his side with your shoulder, not hard, but with a steady equal pressure, and in about ten minutes he will lie down. as soon as he lies down he will be completely conquered, and you can handle him as you please. take off the straps, and straighten out his legs; rub him lightly about the face and neck with your hand the way the hair lays; handle all his legs, and after he has lain ten or twenty minutes, let him get up again. after resting him a short time, make him lie down as before. repeat the operation three or four times, which will be sufficient for one lesson. give him two lessons a day, and when you have given him four lessons, he will lie down by taking hold of one foot. as soon as he is well broken to lie down in this way, tap him on the opposite leg with a stick when you take hold of his foot, and in a few days he will lie down from the mere motion of the stick. how to make a horse follow you. turn him into a large stable or shed, where there is no chance to get out, with a halter or bridle on. go to him and gentle him a little, take hold of his halter and turn him towards you, at the same time touching him lightly over the hips with a long whip. lead him the length of the stable, rubbing him on the neck, saying in a steady tone of voice as you lead him, come along boy! or use his name instead of boy, if you choose. every time you turn, touch him slightly with the whip, to make him step up close to you, and then caress him with your hand. he will soon learn to hurry up to escape the whip and be caressed, and you can make him follow you around without taking hold of the halter. if he should stop and turn from you, give him a few cuts about the hind legs, and he will soon turn his head toward you, when you must always caress him. a few lessons of this kind will make him run after you, when he sees the motion of the whip--in twenty or thirty minutes he will follow you about the stable. after you have given him two or three lessons in the stable, take him out into a small lot and train him; and from thence you can take him into the road and make him follow you anywhere, and run after you. how to make a horse stand without holding. after you have him well broken to follow you, stand him in the center of the stable--begin at his head to caress him, gradually working backward. if he move, give him a cut with the whip and put him back in the same spot from which he started. if he stands, caress him as before, and continue gentling him in this way until you can get round him without making him move. keep walking around him, increasing your pace, and only touch him occasionally. enlarge your circle as you walk around and if he then moves, give him another cut with the whip and put him back to his place. if he stands, go to him frequently and caress him, and then walk around him again. do not keep him in one position too long at a time, but make him come to you occasionally and follow you round in the stable. then stand him in another place, and proceed as before. you should not train your horse more than half an hour at a time. the horseman's guide and farrier. by john j. stutzman, west rushville, fairfield county, ohio. i will here insert some of the most efficient cures of diseases to which the horse is subject. i have practised them for many years with unparalleled success. i have cured horses with the following remedies, which, (in many cases,) have been given up in despair, and i never had a case in which i did not effect a cure. cure for colic. take 1 gill of turpentine, 1 gill of opium dissolved in whisky; 1 quart of water, milk warm. drench the horse and move him about slowly. if there is no relief in fifteen minutes, take a piece of chalk, about the size of an egg, powder it, and put it into a pint of cider vinegar, which should be blood warm, give that, and then move him as before. another.--take 1 ounce laudanum, 1 ounce of ether, 1 ounce of tincture of assafoetida, 2 ounces tincture of peppermint, half pint of whisky; put all in a quart bottle, shake it well and drench the horse. cure for the bots. take 1-1/2 pint of fresh milk, (just from the cow,) 1 pint of molasses. drench the horse and bleed him in the mouth; then give him 1 pint of linseed oil to remove them. for distemper. take mustard seed ground fine, tar and rye chop, make pills about the size of a hen's egg. give him six pills every six hours, until they physic him; then give him one table spoonful of the horse powder mentioned before, once a day, until cured. keep him from cold water for six hours after using the powder. long fever. in the first place bleed the horse severely. give him spirits of nitre, in water which should not be too cold, for it would chill him. keep him well covered with blankets, and rub his legs and body well; blister him around the chest with mustard seed, and be sure to give him no cold water, unless there is spirits of nitre in it. rheumatic liniment. take croton oil, aqua ammonia, f.f.f; oil of cajuput, oil of origanum, in equal parts. rub well. it is good for spinal diseases and weak back. cuts and wounds of all kinds. one pint of alcohol, half ounce of gum of myrrh, half ounce aloes, wash once a day. sprains and swellings. take 1-1/2 ounces of harts-horn, 1 ounce camphor, 2 ounces spirits of turpentine, 4 ounces sweet oil, 8 ounces alcohol. anoint twice a day. for glanders. take of burnt buck's horn a table spoonful, every three days for nine days. if there is no relief in that time, continue the powder until there is relief. saddle or collar liniment. one ounce of spirits of turpentine, half ounce of oil of spike, half ounce essence of wormwood, half ounce castile soap, half ounce gum camphor, half ounce sulphuric ether, half pint alcohol, and wash freely. liniment to set the stifle joint on a horse. one ounce oil of spike, half ounce origanum, half ounce oil amber. shake it well and rub the joints twice a day until cured, which will be in two or three days. eye water. i have tried the following and found it an efficient remedy. i have tried it on my own eyes and those of others. take bolus muna 1 ounce, white vitrol 1 ounce, alum half ounce, with one pint clear rain water: shake it well before using. if too strong, weaken it with rain water. liniment for windgalls, strains and growth of lumps on man or horse. one ounce oil of spike, half ounce origanum, half ounce amber, aqua fortis and sal amoniac 1 drachm, spirits of salts 1 drachm oil of sassafras half ounce, harts-horn half ounce. bathe once or twice a day. horse powder. this powder will cure more diseases than any other medicine known; such as distemper, fersey, hidebound, colds, and all lingering diseases which may arise from impurity of the blood or lungs.--take 1 lb. comfrey root, half lb. antimony, half lb. sulphur, 3 oz. of saltpetre, half lb. laurel berries, half lb. juniper berries, half lb. angetice seed, half lb. rosin, 3 oz. alum, half lb. copperas, half lb. master wort, half lb. gun powder. mix all to a powder and give in the most cases, one table spoonful in mash feed once a day till cured. keep the horse dry, and keep him from the cold water six hours after using it. for cuts or wounds on horse or man. take fishworms mashed up with old bacon oil, and tie on the wound, which is the surest and safest cure. oil for collars. this oil will also cure bruises, sores, swellings, strains or galls. take fishworms and put them in a crock or other vessel 24 hours, till they become clean; then put them in a bottle and throw plenty of salt upon them, place them near a stove and they will turn to oil; rub the parts affected freely. i have cured knee-sprung horses with this oil frequently. sore and scummed eyes on horses. take fresh butter or rabbit's fat, honey, and the white of three eggs, well stirred up with salt, and black pepper ground to a fine powder; mix it well and apply to the eye with a feather. also rub above the eye (in the hollow,) with the salve. wash freely with cold spring water. for a bruised eye. take rabbit's fat, and use as above directed. bathe freely with fresh spring water. i have cured many bloodshot eyes with this simple remedy. poll-evil or fistula. take of spanish flies 1 oz., gum euphorbium 3 drachms, tartar emetic 1 oz., rosin 3 oz.; mix and pulverize, and then mix them with a half lb. of lard. anoint every three days for three weeks; grease the parts affected with lard every four days. wash with soap and water before using the salve. in poll-evil, if open, pulverize black bottle glass, put as much in each ear as will lay on a dime. the above is recommended in outside callous, such as spavin, ringbone, curbs, windgalls, etc. etc. for the fersey. take 1 quart of sassafras root bark, 1 quart burdock root, spice wood broke fine, 1 pint rattle weed root. boil in 1-1/2 gallons of water; scald bran; when cool give it to the horse once a day for 3 or 4 days. then bleed him in the neck and give him the horse powder as directed. in extreme cases, i also rowel in the breast and hind legs, to extract the corruption and remove the swelling. this is also an efficient remedy for blood diseases, etc., etc. to make the hair grow on man or beast. take milk of sulphur 1/2 drachm, sugar of lead 1/2 drachm, rose water 1/2 gill, mix and bathe well twice a day for ten days. cholera or diarrhea tincture. 1 oz. of laudanum, 1 oz. of spirits of camphor, 1 oz. spirits of nitre, 1/2 oz. essence of peppermint, 20 drops of chloroform; put all in a bottle, shake well, and take 1/2 teaspoonful in cold water once every six, twelve and twenty-four hours, according to the nature of the case. cure for the heaves. give 30 grains of tartar emetic every week until cured. process of causing a horse to lay down. approach him gently upon the left side, fasten a strap around the ancle of his fore-foot; then raise the foot gently, so as to bring the knee against the breast and the foot against the belly. the leg being in this position, fasten the strap around his arm, which will effectually prevent him from putting that foot to the ground again. then fasten a strap around the opposite leg, and bring it over his shoulder, on the left side, so that you can catch hold of it; then push these gently, and when he goes to fall, pull the strap, which will bring him on his knees. now commence patting him under the belly; by continuing your gentle strokes upon the belly, you will, in a few minutes, bring him to his knees behind. continue the process, and he will lie entirely down, and submit himself wholly to your treatment. by thus proceeding gently, you may handle his feet and legs in any way you choose. however wild and fractious a horse may be naturally, after practicing this process a few times, you will find him perfectly gentle and submissive, and even disposed to follow you anywhere, and unwilling to leave you on any occasion. unless the horse be wild, the first treatment will be all sufficient; but should he be too fractious to be approached in a manner necessary to perform the first named operation, this you will find effectual, and you may then train your horse to harness or anything else with the utmost ease. in breaking horses for harness, after giving the powders, put the harness on gently, without startling him, and pat him gently, then fasten _the chain_ to a log, which he will draw for an indefinite length of time. when you find him sufficiently gentle, place him to a wagon or other vehicle. note.--be _extremely_ careful in catching a horse, not to affright him. after he is caught, and the powders given, rub him gently on the head, neck, back and legs, and on each side of the eyes, the way the hair lies, but be very careful not to whip, for a young horse is equally passionate with yourself, and this pernicious practice has ruined many fine and valuable horses. when you are riding a colt (or even an old horse), do not whip him if he scares, but draw the bridle, so that his eye may rest upon the object which has affrighted him, and pat him upon the neck as you approach it; by this means you will pacify him, and render him less liable to start in future. means of learning a horse to pace. buckle a four pound weight around the ancles of his hind legs, (lead is preferable) ride your horse briskly with those weights upon his ancles, at the same time, twitching each rein of the bridle alternately, by this means you will immediately throw him into a pace. after you have trained him in this way to some extent, change your leaded weights for something lighter; leather padding, or something equal to it, will answer the purpose; let him wear these light weights until he is perfectly trained. this process will make a smooth and easy pacer of any horse. horsemanship. the rider should, in the first place, let the horse know that he is not afraid of him. before mounting a horse, take the rein into the left hand, draw it tightly, put the left foot in the stirrup, and raise quickly. when you are seated press your knees to the saddle, let your leg, from the knee, stand out; turn your toe in and heel out; sit upright in your saddle, throw your weight forward--one third of it in the stirrups--and hold your rein tight. should your horse scare, you are braced in your saddle and he cannot throw you. indication of a horse's disposition. a long, thin neck indicates a good disposition, contrariwise, if it be short and thick. a broad forehead, high between the ears, indicates a very vicious disposition. cures, &c. _cure for the founder._--let 1-1/2 gallons of blood from the neck vein, make frequent applications of hot water to his forelegs; after which, bathe them in wet cloths, then give one quart linseed oil. the horse will be ready for service the next day. _botts._--mix one pint honey with one quart sweet milk, give as a drench, one hour after, dissolve 1 oz. pulverized coperas in a pint of water, use likewise, then give one quart of linseed oil. cure effectual. _colic._--after bleeding copiously in the mouth, take a half pound of raw cotton, wrap it around a coal of fire in such a way as to exclude the air; when it begins to smoke, hold it under the horse's nose until he becomes easy. cure certain in ten minutes. _distemper._--take 1-1/2 gallons blood from the neck vein, then give a dose of sassafras oil, 1-1/2 ounces is sufficient. cure speedy and certain. _fistula._--when it makes its appearance, rowel both sides of the shoulder; if it should break, take one ounce of verdigris, 1 ounce oil rosin, 1 ounce copperas, pulverize and mix together. use it as a salve. receipt for bone spavin or ring-bone. take a table-spoonful of corrosive sublimate; quicksilver about the size of a bean; 3 or 4 drops of muriatic acid; iodine about the size of a pea, and lard enough to form a paste; grind the iodine and sublimate fine as flour, and put altogether in a cup, mix well, then shear the hair all off the size you want; wash clean with soap-suds, rub dry, then apply the medicine. let it stay on five days; if it does not take effect, take it off, mix it over with a little more lard, and add some fresh medicine. when the lump comes out, wash it clean in soap-suds, then apply a poultice of cow dung, leave it on twelve hours, then apply healing medicine. temperance beverage. one quart of water, three pounds of sugar, one teaspoonful of lemon oil, one table-spoonful of flour, with the white of four eggs, well beat up. mix the above well together, then divide the syrup, and add four ounces of carbonic soda in one-half, and three ounces of tartaric acid in the other half; then bottle for use. sarsaparilla syrup. one ounce sarsaparilla, two pounds brown sugar, ten drops wintergreen, and half pint of water. "the most wonderful book ever written." esoteric anthropology interior science of man. a comprehensive and confidential treaties on the structure and functions, passional attractions and perversions; true and false physical and social conditions, and the most intimate relations of men and women. by t.l. nichols, m.d. 482 pages, 81 engravings, cloth. this book is all that its title indicates.--it treats of the generation, formation, birth, infancy youth, manhood, old age, and death of man; of health and disease, marriage and celibacy, virtue and vice, happiness and misery; of education, development and the laws of a true life. it is intended to answer all questions, and to give the fullest and most reliable information on every subject of a physiological or medical nature--to be a faithful friend in health and disease, and in all the conditions of life, especially to the young of both sexes, and those who are about to enter upon new relations. it contains the highest and deepest truths in human physiology, with their individual and social application; the true nature and hidden causes of disease; the condition of health, physical and passional; all that information which every human being needs, which few dare to ask for, or know how to obtain, but which, amid the discordances of civilization, is of priceless value. the portion of the work on the generative system, is written with entire frankness and fully illustrated, and is unquestionably the most remarkable exposition of the physical, spiritual, and passional nature of man ever written--so remarkable indeed, that it has seemed to many persons to be the result of direct inspiration. the whole subject of the relations of the sexes, or love, marriage, and paternity, is laid open, as it never has been by any other author. a miscellaneous chapter, forming an appendix to this portion of the work, is also of a very remarkable character. it has been truly said, "there can scarcely be any important question, which any man or woman can ever need to ask a physician, to which this book does not contain an answer." the diseases of the generative system, physical and passional, are treated of with great fitness. hundreds of voluntary testimonials to the extraordinary character and merits of this book have been received from persons eminently qualified to judge, among which are clergymen, physicians, lawyers, college professors, etc. we select the following: "i look upon it," says dr. stephens, of forest city, n.y., "as the most wonderful book ever written. it marks a new era in literature and life." "what a pity," says dr. schell, of ind., "that a copy cannot be found in every family in the whole world!" "this book," says dr. dodge, of owego, n.y., "contains more that is weighty in fact, and sound in philosophy; more that is useful in medical science and effective in medical art; more that is purificative and elevative of man than any one work, in volumes few or many that has ever grace the librarie medicale of civilization." "it contains," says dr. baker, of racine, wis. "just such knowledge as a suffering world needs, to enlighten, develop, and ennoble the minds of the people." dr. farrar, of portland, me., says, "esoteric anthropology is vital in every part, refreshing every man's and woman's soul that reads it with a most grateful sense of its truth and importance. i know of no work in the world like it, or comparable with it." "i have read 'esoteric anthropology' with all the deep earnestness and absorbing interest with which i have ever perused the most brilliant romance. it has inspired nobler emotions, and deeper pleasure. 'truth' is more attractive than 'fiction.' the work, i believe to be eminently true to nature--to her unerring laws; i hesitate not, therefore, to pronounce it a noble work. it will be a great blessing to humanity."--prof. allen, of antioch college. the enthusiastic letters respecting it, received, would fill a volume, larger than book itself. sacrificing every personal consideration, and changing his first intention, which was to keep it as strictly private and professional work, a physiological mystery, as its title indicates--the author offers esoteric anthropology to the whole public of readers; satisfied that no permanent evil can result to any human being, from the knowledge of the deepest truths, and most sacred mysteries of the science of life. mark this.--nearly every other work on this subject directs the reader to apply to its author for a prescription in case of sickness, accompanied by a fee; while this, although its author is a practising physician, contains not a line of this kind; its whole tendency being to place every reader, whether male or female, entirely above the need of a physician. * * * * * sent free by mail for one dollar. * * * * * watkin & nicholson, publishers no. 225 fifth street, cincinnati, o. _the attention of lecturers and book agents is especially called to this work as being likely to give more satisfaction to the thoughtful and inquiring reader than almost and other they could introduce._ how to eat a cure for "nerves" ----------------------------------------------------------------------"whosoever wishes to eat much must eat little." cornaro, in saying this, meant that if a man wished to eat for a great many days--that is, desired a long life--he must eat only a little each day. ----------------------------------------------------------------------how to eat a cure for "nerves" by thomas clark hinkle, m.d. rand mcnally & company chicago--new york ----------------------------------------------------------------------copyright, 1921, by rand mcnally & company ----------------------------------------------------------------------the contents page i. where the trouble lies 13 ii. how to overcome the trouble 31 iii. right and wrong diet for nervous people 55 iv. value of outdoor life and exercise 79 v. effect of right living on worry and unhappiness 109 ----------------------------------------------------------------------"nature, desirous to preserve man in good health as long as possible, informs him herself how he is to act in time of illness; for she immediately deprives him, when sick, of his appetite in order that he may eat but little." --cornaro ----------------------------------------------------------------------the introduction this author-physician's cure for "nerves" vividly recalls the simplicity of method employed in the complete restoration to health of one of olden time whose story has come ringing down the ages in the book of books. naaman, captain of the host of the king of syria, a mighty man of valor and honorable in the sight of all men, turned away in a rage when elisha, the prophet of the most high, prescribed for his dread malady a remedy so simple that it was despised in his eyes. but "his servants came near and said ... 'if the prophet had bid thee do some great thing, wouldest thou not have done it?'" in "how to eat" the author offers the sufferer from "nerves" a remedy as simple as that elisha offered naaman. he gives him an opportunity to profit by his well-tested knowledge that overeating and _rapidity_ in eating are ruinous to health and shorten life. it is seldom that there emanates from the pen of a doctor a book which, concerning any physical disorder, minimizes the efforts of the medical practitioner. while this author-physician gives full credit to the conscientious physician for the great service he is able to render in all other spheres of his profession, he wholly denies the necessity for medical care in cases of nervous breakdown, and discounts liberally the benefits to be derived from professional advice except in so far as the doctor is the patient's counselor and dictator as to what and how and how much he shall eat and drink, and the way he shall employ his time. any discourse is valuable which incites a man having a marked tendency to depressing, morbid ideas, to rid himself of them. dr. hinkle helps the sufferer to gain that confidence and cheer which result from knowledge of certain immunity from dreaded ills and positive assurance of recovery by mere regulation of food or employment along the lines of simple, everyday living. but that alone is not sufficient. it is made quite clear that no one thing by itself will insure a cure of "nerves." the cure must come through common sense exerted along several related avenues of endeavor. no matter how steadfastly one may adhere to directions as to abstaining from harmful food and injurious methods of partaking of those foods which are beneficial, if he spends the larger portion of his time idly rocking in a convenient arm chair, exerting neither body nor mind nor will, that which might be gained by proper nutrition is largely nullified by lack of physical exercise and mental activity. that this little book may serve as a spur to the bodily self-denial and self-repression and the intellectual and spiritual uplift which make for character-building, is the very evident goal of its writer. from self-analysis and self-cure he has worked out a philosophy--a system or _art_--by which those afflicted with nervous breakdown may be healed. and by putting into print the result of his practical experiments in diet and exercise he has broadened immeasurably the scope of his helpfulness to all nervebound sufferers by placing within their reach the simplest of measures by which release is secured from a condition which wholly incapacitates for active service or even for quiet, everyday usefulness. it is because the things dr. hinkle advises are so commonplace, and because the doing of them day after day, year in and year out, is so monotonous, that people will be tempted to disregard or make light of their helpfulness. but the commonplace things which make up life are all important, as susan coolidge has so aptly expressed in these lines which fittingly illustrate the author's thought: "the commonplace sun in the commonplace sky makes up the commonplace day. the moon and the stars are commonplace things, and the flower that blooms and the bird that sings; but dark were the world, and sad our lot if the flowers failed, and the sun shone not; and god, who studies each separate soul, out of commonplace lives makes his beautiful whole." it therefore behooves the sufferer from "nerves" and that great host of others who are in danger of a nervous breakdown if they do not speedily mend their ways of eating and living, to heed the kindly admonitions and follow the precepts of this author who practices what he preaches. by persistently doing commonplace things in the most commonplace way, keeping ever in mind the great objects to be attained thereby--good health, good cheer, and increased usefulness throughout a long life--the reader of this little treatise will find it worth many, many times its size, weight, and bulk. and heeding the author's admonition, "go thou and do likewise," he will not shorten his life or lose it altogether in fruitless quests for the strength and nerve vigor which constantly elude him because of lack of self-control and failure to persist in the simple but efficacious measures of relief here outlined. m. f. s. ----------------------------------------------------------------------how to eat a cure for nerves i. where the trouble lies "what we leave after making a hearty meal does us more good than what we have eaten." --cornaro it is now over twenty years since i had my first nervous breakdown. about ten years later i had another, far worse than the first one. the first lasted six months; the second a little more than two and one half years. doubtless if i had not in the strangest way in the world found out how to cure myself it would have lasted until now, unless death in the meantime had come to my relief. but right here i want to say that if you are looking for some new or miraculous treatment for such unfortunate people you might as well close the book now, for you will be disappointed. there is a cure for "nerves" but the cure is as old as the world. the trouble with poor deluded mortals--doctors included--is, we are constantly looking for a miracle to cure us, but if we look back on all the real cures that we have ever heard about, we shall find they were as simple as the sun or the rain. and in the name of common sense let me ask: what is the difference _how_ we are cured if we _are_ cured and are _happy_ as a result of it? isn't that enough? most certainly it is. and now, as we journey along through the pages of this book, i want you to know that these words have been written by one who has nothing to offer you except human experience. as we proceed you will notice that every statement is tremendously positive. when a man has been through this literal hell of "nerves" he knows all about it and what can be done for it. and so when i tell you the things you must do to get well and _stay well_, i want you to understand that i know. there is absolutely no theory to be found in these pages. if you put your finger in the fire you burn it. you don't have to take your finger out of the fire, call in a lot of learned gentlemen and say to them: "now tell me your candid opinion about my finger. is it burned or is it not?" and i am just as positive about my cure of "nerves" as you could be that fire burned your finger. that brings me to what i want to say about the so-called "rest cures" at the sanitariums. it is a well-known fact that if a case of "nerves" is pronounced cured at a sanitarium the cure is only temporary. sooner or later every one of these patients goes down hill again. and remember i am talking about people who have nervous breakdowns through no fault of their own. i have no time to spare for the person who has brought on his own trouble. i am chiefly concerned with that host of children in america--and there is a host, i am sorry to say--born of what i choose to call "pre-nervous" parents. the girls of such parents frequently break down in high school. and many of the finest boys that i know have this dreadful "thing" fastened firmly upon them just at the very beginning of their lifework. you may think i am a little vehement, but to me one of the most damnable and disgusting things in the world is that the medical profession remains so ignorant concerning the _real cure_ for such cases. i believe the late sir william osler was the greatest physician of his generation. he was not only a man of talent, he was a genius, and his knowledge of medicine almost passes understanding. yet osler himself was as much in the dark concerning the _real_ cure for so-called _neurasthenia_ as the physicians who read his works on practice. if one wants to find out how ignorant the whole profession is on the subject of a permanent cure, let the thing get hold of him, and then let him make the rounds of the physicians, follow out their advice, and see where he comes out! i have said that even the sanitariums of this country--and for that matter i might have said of any other country--do not _permanently cure_ these people. i have ample proof of this statement. i have met these people everywhere and no doubt you have, too. quite recently the subject was brought up anew to me. i had written an article on the subject for one of the magazines, a magazine having a large circulation. in a very short time my mail was literally flooded with letters. every incoming mail brought great numbers of them. they came from physicians of the regular school, and from physicians of many other schools, too. i won't mention any of them, for this is a treatise on a dreadful affliction and how one may get rid of it; it is not intended as a criticism of anyone. i have no desire to criticize and i haven't time. i am stating facts interwoven with my own life. if the cure is real, the people will find it out after they have tried it; if it is not, they will also find that out. in fact, it's exactly as gamaliel, the teacher of paul, said to the men of israel when they would have slain the apostles for teaching christ's sayings, "refrain from these men and let them alone: for if this counsel or this work be of men, it will come to naught: but if it be of god, ye cannot overthrow it." and it's exactly the same way with this healing art. the very fact that physicians of all schools of medicine--physicians who were sufferers from "nerves"--wrote me, shows plainly that they could not heal themselves. i have many letters from people who have been in sanitariums for years and who still have "nerves." the sanitariums do some people a lot of good, but they cannot remove the _cause_ of nervousness. i am certain that the very best rest cure for women is the one dr. weir mitchell first used. but such women are sure to go down again and again and still again if that is _all_ that is done for them. now frankly, if christian science could cure such cases and make them _stay_ cured i should want a practitioner of this cult to treat them. but christian science simply cannot cure them because the underlying cause of this trouble is _physical_, not _mental_. in other words, the mind becomes ill because the body is made ill by certain poisons, and the nature of the disease is so peculiar that most of these miserable sufferers will not even try a thing unless some one brings them overwhelming evidence of its having wrought a cure. or, if they do try it, they usually quit the treatment before nature has had time to do her work and set their bodies right. i have the most profound sympathy for such people. i want to speak directly to them. that is the task that i have set myself in this work. i want to talk directly to those of you who are sufferers from "nerves." i see you in every state, in every city, in every village, and throughout the farming districts of this country. i have received letters from many farmers who are suffering with this "thing." to them let me say, i know just how you feel, and from the very bottom of my heart i pity you. i know the horrible suffering of each one of you. i don't care what your ambition has been or is. i don't care what your situation in life may be. i don't care how rich or how poor you are. i don't care how much trouble you have had, or the nature of it. i want you to know these words are being written by one who knows more about your sufferings than you can imagine. i want you to believe this, because it is true. if you have longed and prayed for death, remember that the one who is writing these words also has longed and prayed for death. but one thing you must be sure to remember: while you are waiting and trying to get well you must have _patience_. i recollect one beautiful day in early spring when traveling in nebraska i passed a little cemetery. how sweet and restful the place seemed, and as i looked out over those little white stones i prayed silently that the great god who made me would not hold me much longer on earth, that he would soon grant me the rest and peace which i believed was to be found only in death and the grave. but _remember this_: in those dark days never for a moment did i think of taking my own life! these words may reach some one who has had such a thought. if so, i say to you that to take one's life is the most cowardly thing a human being can do. this is the only place where i feel like being severe with you people. shame on the man or woman who will not go on to the end fighting honorably! and now if you have ever given thought to such a thing, blot it from your mind forever. i can see how these miserable people might long for death, as i did. but no matter how we may long for release through death, the god of nature must be the judge of our time of going. now this brings me to what i want to say about such sufferers going insane. believe me, they never do! remember this always. you won't become insane. you couldn't if you tried! in letter after letter among the flood of them i have had from all over this country and canada, i read how the poor sufferer feared he or she might be going insane. i know, poor souls, just how you feel. that feeling is, i think, the most dreadful of all things connected with "nerves." i suffered from it for years. it is a dreadful feeling, but there is not the least bit of danger of such a thing happening to you. you will _not_ go insane. such persons can't. do you really get me? such persons cannot go insane. this disease is nothing but what we call a functional nervous trouble. and so forget about the danger of insanity for all time. you can be cured, but you will make your return to health just that much slower by harboring this fear. and it would be simply foolish for you to go on thinking it possible after i--let me say it again--after i have told you that it cannot happen. for the value of this treatise lies in the "i." its value is just like that of the treatise by cornaro. he lived it. and so likewise have i lived it. i have been laid low with this malady. i have staggered in black despair with staring eyes and bleeding feet and crying soul along this road strewn with thorns and stones. i know what it is to lie awake all night and cry like a baby, with none to know and none to tell me what to do. i know what it is to be tremendously ambitious. ambition! ambition! ah, god of heaven! how a poor soul suffers who beyond everything else, craves to be able to do something big in this world because he knows he should, yet is held down by this dreadful thing, "nerves!" and how little, how unspeakably little, do physicians, even the greatest of them, know, actually know, how we suffer, unless indeed there be one in whose own body the fiend has sunk deep its talons. after i had my first breakdown i made up my mind to study medicine because something told me that i was one of those "peculiar" people who just _think_ there is something the matter with them. is it not strange that with all the advance that has been made in general medicine, little or nothing has been done for the relief of the people born with this curse hanging over them? i wish this book could be put into the hands of every nervous parent for, think as you may, all nervous parents beget nervous children. but does it follow that such children should have a nervous breakdown almost before they are out of their teens? no, decidedly not; and what is more, they never should and never would break down, if they had proper food. i look back with horror on the many nights of my childhood when i suffered with "night terrors." and right here let me say: no child will _ever have night terrors_ if he is given just what he should eat, and is kept from overeating. and now a few words about the _first_ great point concerning the prevention as well as the cure of "nerves." nervous people, and many others as well, eat too much. that, you say, is nothing new. but that is just where the dreadful wrong begins; and why there has been tragedy after tragedy, and why even while this is being written there will be many more tragedies. you will hear lecturers say--i myself have said it, and to large audiences: "you people eat too much." but if that's all that is said, people straightway go away and say: "oh, yes, he's right, of course. we all eat too much." and there it ends. until recently people did not know--most of them don't know yet--that each day they are actually bringing the grave nearer by overeating. not long ago the great life insurance companies of this country held a notable convention in the city of new york. now after everything had been said and done, after every phase of life insurance had been discussed, what do you suppose was the great outstanding statement from that remarkable body of men who know more about why people die than any other body of people on earth? it was this: "the average american _man or woman_ dies at the age of 43 because he eats what he wants to eat rather than what he should eat." that means, of course, that practically all americans overeat. they are all like the child who says, "i'm not hungry for bread and butter. i'm hungry for cake." and i find that most of these poor deluded nervous sufferers eat what they want under the supposition that it is good for them because they crave it. i myself used to do so. i would eat candy by the pound. and it is odd but quite true that nervous people crave the very things that hurt them most. but there is no more sense in eating what you crave because you crave it than there is in the man who is addicted to alcohol, drinking alcohol because he craves it. i once used tobacco; i craved it, but i did not need it just because i craved it. it is true the body naturally needs some fats, some carbohydrates; in fact, a balanced ration, as we shall see later. but i want to make it mighty plain here that never was there a greater error than that of supposing you need chocolates or sweets just because you crave them. and you don't need to overeat, and keep on doing it, just because you must eat. ii. how to overcome the trouble "he who pursues a regular course of life need not be apprehensive of illness, as he who has guarded against the cause need not be afraid of the effect." --cornaro we have now come to the second step in the cure of "nerves"--eating the right food in the right way. you must chew all food until it is of the consistency of cream, and you must also sip all liquids slowly. and now, as you read these things that i have set down, i want you to remember this: doing any one thing--and doing that alone--will not cure this malady. no, it is doing a number of things at the right time. i know this is true because i have tried it. for a time i chewed my food to a cream, but that was the only thing i did in an endeavor to get well. i was doing none of the other things that are absolutely necessary for a cure. this is one great trouble with all such people. they will fletcherize for a time and then say there is nothing to that because it does not cure them. well, as i've said, that alone will not, and i want to dwell at length on this because nobody knows as well as i do, what harm such a belief does the nervous sufferer. trying out fletcherizing alone, which i say must be done together with other things if you want to get well and stay well, is like taking the handle of an axe and going out into the woods to cut down a tree. now with fletcherizing you have a perfectly good handle, but you know very well that you can't cut a tree down with only an axe handle. but that is not the fault of the handle. the fault is obviously your own. now suppose you get the axe and fit the handle to it. you can then cut the tree down if you work hard enough at the task. again, suppose you cut the tree half way through and quit. will the axe keep on until the work is done? you know it will not, and you very well know if you wish to be cured you must keep on doing your part of the work or dieting will be of no value whatever to you. now suppose a man comes along and tells you that the axe you have is no good and therefore it is no use for you to keep on trying to use it. that is exactly what some physicians still say about fletcherizing. but you say, "i must cut this tree down. nobody will do it for me; how shall i get it down? can you give me an axe that will cut it down?" "oh, no," he replies, "but anyway there's no use fooling with that one." then, if you are determined to do the work, you say, "i have to cut the tree down. you have no other axe to offer me, so i'm going to try the one i have." and you go ahead and cut down the tree. then just as you have finished, the man comes your way again, and in great delight you call out to him: "come and see! i cut this tree down with the axe you said was no good!" the man comes over to you and says, "where's the tree? i don't see it!" you are astonished and you tell him, "there it lies on the ground right before your eyes! can't you see it?" but he turns and walks away saying: "there is no tree there; it is all in your mind." this is exactly what people with "nerves" have been told again and again by physicians, by relatives, and by most other people who have never had "nerves." i tell you these things so that when you begin to eat sparingly and chew your food to a cream you may fortify yourself against well-meaning but mistaken friends and relatives. and, oddly enough, it does seem that the individual with "nerves" has more friends and relatives than any other person in the world. remember you must not only chew your food to the consistency of cream for one or two months, you must make this practice a lifelong habit. if you cannot take time to eat a meal in this way, you had much better go hungry. to people who travel and must frequently take their meals in railroad eating houses, i would say, get some bread and butter sandwiches and eat them slowly while on the train. there is always a chance to secure all you need to eat, too. you may not always be able to sit an hour at the table--the time we should give to a meal if we eat as we should. i know many object to this rule on the ground that if we followed it we should get nothing else done. but that is nonsense. did not the master of us all say, "are there not twelve hours in the day?" then can we not devote three of the twelve to our food? if we have nine hours in which we are at our highest efficiency, is it not good sense, if we eat three meals a day, to give three hours to these meals? there is only one sane answer to the question; we should take an hour for a meal. every now and then some magazine writer will state that the chewing of food to a cream does not help anybody. he will tell you that you can swallow your food any old way and it will not hurt you in the least. in fact, i actually saw an article in one of our leading periodicals containing just such statements. we should, i suppose, have only pity for an editor who would give space to such stuff, and should also pity the poor wretch who by writing it is striving to attain notoriety. at any rate there is one excellent thing about such lies, they do harm for only a little while. when people find out that a thing is harmful to them, they usually quit it, no matter how many notoriety seekers are urging and encouraging them to keep on. usually the sufferer with "nerves" is the only one in the household who will eat sparingly and chew his food slowly. but now and then i find an intelligent, sympathetic man who will do so because it is helpful to his wife. he sympathizes with her infirmity, and with fine self-denial eats as she does. and note this: he usually derives benefit from so doing. time after time when i have put a nervous woman under this regimen, and then her husband elected to go along with her, i have had the man come to me and say: "well, doctor, i declare i'm feeling a whole lot better myself! i don't get sleepy any more during the daytime, and that pain i used to have in the region of my liver is gone!" and so on and on. the fact is just this: anybody who follows the rules that i learned to apply in my own case cannot fail to be benefited. and although those not inclined to "nerves" can eat a greater variety of food, it's greatly to be desired when there is a nervous person in a household of grownups that all other members of the family enter together into this thing. it could not fail to help every one of them. to be truthful, in the beginning you will all find it mighty hard to persist in chewing all your food to a cream. mouthful after mouthful of food will get away from you when you are not thinking. this just goes to show how we are in the habit of bolting our food. at first people who fletcherize or chew their food perfectly, usually lose weight. i most certainly did. i lost about twenty pounds because of it, but i was so well and felt so good i could almost have jumped over the north star. i know that, unfortunately, a lot of people with "nerves" have started to chew their food carefully and to eat sparingly, but the minute they found themselves losing weight they were frightened and quit. they went on carrying that ten or twenty or thirty pounds of flesh and all the time suffering the tortures of the damned just in order that they might keep it. but of what benefit are a certain number of extra pounds of flesh and how can a man explain such a senseless action? the astonishing thing is that many physicians are willing to condemn a cure just as soon as they find the patient has lost a pound of beef. but as i said before, the primary mission of man in this world is not to raise beef. i do not find fault with the raising of beef in the feeding yards, but if beef must be raised let us confine the industry to the cattle pens and stock yards. let us not worship it to the degree that we would rather live in hell than part with a few extra pounds that overload our own bodies. now just here i want it distinctly understood, as i have said before, that this text is primarily for _functional nervous cases_. tubercular people belong to an entirely different class. they should live out of doors day and night and should, if possible, be treated at outdoor institutions established for such cases. but the individual with "nerves" will find what he needs and will find it abundantly if he has enough determination to take hold of it and keep at it. on the part of many it will take all the determination they have to chew their food to a cream and always eat sparingly. in regard to the amount of food taken, judgment must of course be used. we all know that it is possible to eat too little. but you should always quit eating while you still feel you would like a little more. i know of no better guide than this to offer you. but i have observed that the person who eats slowly and chews his food to a cream never eats as much food as he would if he bolted it. it is just like letting a thirsty horse drink water. i remember, as a boy on the farm, when i led a very thirsty horse from the field to the water tank how rapidly he would swallow. if my father were with me, after the horse had drunk a while he would say, "make him hold his head up." frequently when i did so the horse would draw a long breath and drink no more. had he gone right on drinking, as a thirsty horse will if you permit him to do so, he might have drunk twice as much as was good for him. and that's the way people eat. as a result the horse that drinks and drinks and drinks when he is very thirsty sometimes dies in a few hours. i have seen a horse die from drinking too much water and i have also seen people die in a few hours after a terrible gorge that they could not get rid of. do you know that most nervous people have a way of sitting down to the table and eating until they are literally full? if you could take out the stomach of such a person and look at it, the sight would frighten you. and with good reason. for as a result of this habit many nervous people have dilated stomachs. but if they would correct their manner of eating there is usually enough tone in the muscular walls of the stomach to get it back to normal. i marvel again and again over how miraculously nature restores herself even after she has been terribly abused, if only she is given a chance. i am certain that all human beings would be more efficient if they chewed all solid food to a cream and sipped all liquids slowly. the late professor william james, the great harvard psychologist, testified to the value of such a habit, as did a number of other distinguished harvard professors. i regret that some physicians still hold out in their belief that it does no good although the evidence stands out as clearly before them as a tree along the roadside. but they are like the physician who some years ago declared that bathing was bad for people. i recall how hard we all bore down upon him, as he richly deserved, and how the journal of the american medical association printed a short poem ridiculing him. i am quite certain that the members of the regular school of medicine have progressed infinitely farther toward the cure of diseases than members of all the other schools combined. i do not say this simply because i happen to be a physician of the regular school; i say it because a candid survey of what has been accomplished, and by whom, proves it. but as to diet, we have done little compared with what we should do. we have made no greater progress along this line because so many of us have been blinded by prejudice--the curse of the human race. with regard to chewing all food to a cream, most modern writers on dietetics, while acknowledging that this super-mastication is useful, maintain that it does not increase the value of the food. but they err greatly in this, as we can prove in a very few words: if a certain amount of proteins, fats, and carbohydrates is bolted by a nervous man suffering from a breakdown, it will cause intestinal toxemia as a result of the bolted food, but if he chews the food to a cream it will be digested in a normal manner and will not cause gas in the stomach or intestines. the proper amount of food is absorbed and nourishes the man as it should. now did not the thorough mastication of that food increase the value of the proteins, fats, and carbohydrates? the thing is a self-evident fact. in the first case a man takes food which quickly turns to a loathsome poison. in the second instance the same kind of food is so thoroughly mixed with the ptyalin in the saliva that whatever is eaten becomes of value as protein or fat or some other food element. after many years of sad experience with this malady we call "nerves" i am convinced that the reason why people have this disease is because they are literally "food drunk." i have treated men who had been on an alcohol debauch and i know how terribly depressed they are after such a spree is over. it is exactly the same way with the pre-nervous people that break down. they sit down to a big meal and overeat. there is a temporary stimulus, just as in the case of the person who takes intoxicants, followed by that terrible mental depression that all who have suffered from "nerves" know. and because the individual with the "nerves" is overeating two or three times each day, he stays drunk with the poisons that form in his stomach and intestines. such people over-assimilate the poisonous products of proteins, especially of sugars. of course this may seem oddly stated because we would not want any absorption of the poisons in the intestines, but it is probable that nature can and does take care of a little of it there in the healthy individual. it is perfectly absurd to say, as some physicians still continue to say, that no poisonous matter is ever absorbed in the intestinal tract. give a child something that causes intestinal indigestion and see how quickly he has a rise in temperature. this fever is the direct result of poisons absorbed in the intestines. in the case of the nervous adult, however, this poison does not as often result in fever as it does in a horrible mental depression and a complete inability to perform any sort of work. and so there seems no question but that this terrible malady we call "nerves," or a nervous breakdown in any of its many forms, is in a majority of cases the result of the wrong eating habits of the individual. the chewing of all food to a cream will go far toward curing the trouble, but in most cases this alone will not effect a cure. it would not have done so in my own case, although i did see much improvement as a result of that practice alone. and here i want to say this: there are many who say they cannot eat acid fruits because of the distress they cause. now if such people would always chew an apple, a pear, or other fruit to a cream, no distress would result from eating fresh fruit. but such people must follow in detail the diet i shall give farther on. now, facts cannot be stated too strongly. it is certain acid fruits will cause distress if you do not chew them to a cream. i would swell up like a toad if i ate only one apple hurriedly. i don't dare think what might happen to me if i ate three or four in that way. i might possibly find myself transformed into a human balloon and float away into space. but i don't eat apples that way--not now. some who read these pages may think it very strange, yet it is quite true that there really are persons suffering with "nerves" who have not gumption enough to follow this simple rule of chewing all food to a cream. i despair of ever helping those people. they still continue to dispose of a big meal in fifteen minutes, and then insist they have chewed all their food carefully. i have had that thing happen right before my own eyes. then think of their complaining that they cannot eat apples because they cause so much gas in the stomach! one reason why a large number of such people are troubled with gas, even though they do chew their food to a cream, is because they immediately follow a meal with one or two cups of tea or coffee. now please remember this: an individual afflicted with "nerves" has no business drinking either tea or coffee. he should let them both alone. plain hot water is the very best drink in the world for a nervous person. if you want a drink after your meal drink a cup of plain hot water. and you should also drink a cup of hot water half an hour before breakfast. if you do not care for breakfast, and feel you do not need this meal, drink the hot water anyway. the victim of "nerves" should never drink during the meal but after it, if he must drink anything at all. he should also drink a pint or more of cold water between meals every day. now, another thing with regard to chewing all solid food to a cream. it has been proved over and over again in my own case and in that of many others, that in doing this the brain and muscles are both made stronger and keener for work, that those who chew their food in this way have much greater endurance, both mental and physical, than those who do not. today if i should relax my vigilance in respect to chewing my food i should soon go down again. but with this aid, which i now so easily employ, combined with exactly the right things to eat, i find i need have no fear. it has been ten years since my last breakdown and in that interval i have done the very best work and by far the hardest brain work of a lifetime. i do not believe people break down from overwork. you may think that a perfectly absurd statement. but i have good grounds upon which to base my belief. if nervous people would eat sparingly and chew their food to a cream, eating the foods i shall mention later on, i am confident they would rarely, if ever, break down. it is certain that in the last ten years, with the greatest mental strain on me, i should have gone down again, and perhaps more than once, if i had not found what caused "nerves" and how to prevent it. in the meantime i have written ten or more books, and every writer, at least, knows what a nerve-racking profession writing is. in addition to all this mental labor i have gone right ahead with my medical practice. surely there is balm in this particular gilead. but if you will not chew your food to a cream you need not expect to win the entire reward. and you must do this not only one day or one week or one month or one year, but all the days, weeks, months, and years that you may live. and, alas! i know only too well all the trouble well-meaning but deluded people who sit at the table with a nervous individual will make him when they discover how much time he is taking to chew his food. at first, because of the length of time i spent at a meal, such people thought i must be eating as much as a horse. but, here and there, for i was in many places, when people found out what i was doing, they would only courteously deride me for being so gullible about what they termed fads. we are all well aware that the vast majority of americans do not chew their food to a cream or anything like it. and there are those, therefore, who advance as an argument that because the majority do not there must be something wrong with the minority who do. well, let us follow this out a little: not so many hundred years ago everybody believed the world was _flat_. but their theory did not make it flat. and so, even though thousands of people who crowd our eating houses do bolt their food, that does not prove there is no danger in the practice. and they who do it are digging their graves with their teeth. _chew your food!_ iii. right and wrong diet for nervous people "he who leads a sober and regular life, and commits no excess in his diet, can suffer but little from disorders of any kind." --cornaro people who are the offspring of nervous parents and who have had a nervous breakdown should not eat commercial sugar, eggs, or animal food of any kind whatever. these statements may seem wholly unimportant to some people, but i realize what a tremendous bomb i throw into the camps of others when they read them. you see, for centuries people have believed meat and eggs to be the best of all foods; so when i make a statement like the foregoing, the effect is not unlike that which followed columbus' statement that no matter what people believed, the fact was that the earth was round, not flat. from the very beginning it has not made a single bit of difference as to what physicians or anybody else thought; facts count. and no matter what we may think or how long we have thought it, facts go right on being facts just the same. sometimes, even after twenty years' experience, about once in two or three months--because there is nothing else at hand--i find myself eating a small bit of meat. this usually happens when i am on a lecture tour. but if i eat only a small slice of bacon at the evening meal i dream bad dreams and the next morning feel drowsy, heavy, and sluggish. animal foods as well as eggs and commercial sugar poison all those born of nervous parents. i have proved the truth of this by my own case and by several years' observation of other cases. do your children have "night terrors"? you answer, yes. well, let me tell you how to stop these horrors in the little ones. if you give them meat--and remember you should never give them pork--let them have a very small piece at noon, never at night. and they should never be permitted to have it for breakfast. give the child his one small bit of meat at noon. for the evening meal give him some cereal with milk or cream, but no sugar. give him all he wants of this special dish, but nothing else at that meal, and you will find his "night terrors" and moaning will cease. i look back on most of the nights of my childhood with horror, for until i became a man i talked in my sleep and had the most horrible dreams. i used also to get up in my sleep and walk about the room. my parents were well aware of the fact that all of their eight children were poor sleepers, and of them all i was by far the worst. and, although it was innocently done, the food they were giving us was poisoning us. you don't need to think that in order to take poison you must have strychnine or arsenic. no, indeed you don't. we were fed exactly as hundreds and thousands of poor little ones are being fed now as this is being written. we were fed on meat, eggs, and fats, and when we became ill, friends round about us thought they were doing something real kind when they sent in a nice piece of fried rabbit or some celebrated golden brown fried chicken. but we vomited at the sight of the food--which was really our salvation. i have two boys of my own. the elder, a sturdy chap not yet ten years of age, has to have clothes for a fourteen-year-old boy, and he is much stronger than any boy of his age he has ever met. the younger boy is now seven and his physical development is wonderful for a child of that age. now these boys hardly know what an egg is. they never eat one. as to meat, i am certain that since they were born they have not eaten it on an average of once a week. they have eaten a little, but you will admit that eating meat not more than once a week, and often going weeks without a bit of it, certainly is eating very little. there have been times when they have not seen meat for three months. now, i don't eat as i do and have my children eat as they do just for a fad. i think nothing is more stupid and silly than for people to do certain things just because somebody else does them. we should all have good sound reasons for our actions in this world. we should all try our very best to use sound common sense. that's why i say that people who are the offspring of nervous parents should not eat animal food of any kind after they are twenty-one, and they should never at any time eat eggs. it would be far better for them if they did not eat commercial sugar. but i do admit that when some of these people get well by dieting, they are able to eat sparingly of all these things and still keep well. but some people can never eat them and i am one of the number. i remember one summer about two years ago i was on a lecture tour for a chautauqua bureau, and it seemed that surely i got into the very worst eating places that summer that i ever had in my life. for three or four days i ate only eggs, as they seemed to be about the only food i could get besides bread and butter. at the end of the third day--i remember the time very well--when night came i could not sleep, and just as when i had one of my nervous breakdowns, that old feeling of inexpressible gloom began to settle over me. i knew instantly the cause of it, because twice before when i had purposely experimented with eating eggs i had had similar experiences. i immediately took a heavy cathartic and after having thoroughly rid myself of the poison i again slept well. but i am not alone in this fight against the use of eggs for nervous people. john burroughs said that eggs poisoned him, and i have talked with men of great wealth and great business ability who have reached the top by their own efforts, who have told me that eggs poisoned them. now i have found that for these nervous people animal food is a slow poison. sooner or later it will do its work. and just here i wish to say that there are some people who seemingly can eat almost anything and not suffer from so doing. last summer i talked with count ilya tolstoy, son of leo tolstoy, the celebrated russian writer. the count, who is also a lecturer, told me that he was obliged to have eggs and that he had eaten them all his life. he said his appetite was never satisfied unless he ate eggs. he is now past sixty, and apparently is strong and rugged. now eggs no doubt are good for him. but right here is where infinite harm can be done to nervous people like myself. people who can eat everything--and among physicians seemingly there are many who can do so--will say to these poor sufferers: "why, it's all nonsense about things hurting you! eat anything you want and all you want and then forget about it." physicians have said that to me and during the past twenty years i have heard them say it thousands of times to others. personally i do not believe in christian science--physicians of the regular school do not believe in it; but do you know that when a physician says to a sufferer from "nerves," "it's all nonsense about what you eat hurting you; eat anything you want and then forget about it," that physician is fully endorsing christian science. he is telling the person to whom he is talking that there is no such thing as physical suffering. of course, such a physician is nothing but a fool. yet that's why so many of these people turn to christian science. yes, that is exactly why they try it. it bolsters up a sufferer for a time just as contact with a magnetic and hopeful personality may for a time bolster one up. but such persons almost always go back to the sanitariums. "nerves" is not a mental disease; that is, the seat of the trouble is not mental but physical, and the mental phase of "nerves" is only a symptom, or rather one of the symptoms of the disease. we people who have gone down into the dark valley have experienced a million, more or less, different kinds of feelings. i fully believe one half of the american people are the offspring of nervous parents. this means that there are fifty-five million of this nervous type of americans. this type includes people all the way from the man in an office who gets angry quickly, to the individual who is in a state of complete collapse. and the man who is afflicted with nothing more than a quick temper, or is living under high nervous tension, is liable to beget children who will suffer from the malady in a far worse degree than ever he will, unless, indeed, he eats only the things he should eat and observes a number of other rules besides the two i have already laid down. now, the ideal diet for nervous people is a slightly modified vegetarian diet. to be specific, it is a lacto-vegetarian diet minus eggs. there are, however, two things included in this diet that i would warn one in the beginning to eat of sparingly. these are bananas and cooked cabbage. if they agree with you, well and good; but if they do not, let them strictly alone. eat all kinds of vegetables, both fresh and cooked. eat all kinds of fruits, especially fresh fruits. there is an old saying and a good one, "an apple a day keeps the doctor away." there are a thousand ways to prepare vegetables and fruits for the table, and there are a number of books that give good recipes. if a nervous individual has never yet had a breakdown i believe he can safely eat most of the vegetarian dishes that have eggs in them, but it would be a serious mistake to select the special dishes that contain eggs and live on those just because they contain eggs. i believe, too, that after a nervous person is restored to health, if he strictly observes the rules of eating sparingly and of chewing all food to a cream, he may safely try out such courses as are found in _bardsley's recipes for food reformers_ or _broadbent's forty vegetarian dinners_. it may seem odd, but there are people who for some reason or other lack the instinct, or whatever is needed, to know that a certain thing they eat hurts them. i have had men and women sit in my office and say with the utmost sincerity that they were certain that it wasn't anything they ate that hurt them because they never had any pain in the abdomen. sometimes these people were in a dreadful state of nervous breakdown. so you see the danger that lies here. if you know, you can always tell what special thing disagrees with you. for example, i know eggs disagree with me, and like john burroughs and many others, i know when they harm me. therefore, after you have recovered you might try being your own physician. but if you are not sure as to what disagrees with you, you would much better stick to a vegetarian diet and go without eggs the remainder of your days. commercial sugar also is the cause of many breakdowns among the people of this country. and is it not strange how these poor suffering people crave sweets--the very thing they should not have. they will argue with themselves--and some physicians will agree with them--that they should go right on eating candy because they want it. but, as i have already said, there is just as much sense in saying a man should have whiskey because he craves it or that a young man should have tobacco because he craves it, as to say that any one should have candy because he craves it. there is absolutely no sense in such an argument. if you are suffering from a nervous breakdown, for sixty days quit eating candy and everything sweet except honey, and follow the other rules i have already laid down. it may be that you will have to stick to this diet for three months. but try it. that is exactly what cured all my bodily ills and brought my soul out of the dark and gloomy night after everything else had failed. i do not mean to say that this diet alone cured me, but i do say it was the biggest factor in the cure. there are, however, some other things that it would be worse than folly to ignore. this i shall come to later. but just here i want to have it understood that this thing of eating--how you eat, and how much you eat, and what you eat--is of transcendent importance in the cure. of course, under some circumstances connected with cases of breakdown, nothing but the good judgment of friends will avail. for example, the question of how much one shall eat is something that not all the books in the world nor all the physicians in the world can determine. i say, always quit while you want a little more. i cannot say more or less than that. so many have written me recently asking just what i eat, that it may be a help to some of them if i set down here just what i ate today. i ate no breakfast at all. sometimes i go for weeks without eating breakfast. this is especially apt to be the case if i am engaged in writing a magazine article or a book. i find my brain is much clearer and that i can work much better when i eat no breakfast. but i do drink one or two cups of very weak tea. i use just enough tea to color the water. now i do not advise everybody to go without breakfast. some people tell me that they have a headache unless they eat something. and some writers say that if they do not eat a little breakfast they cannot write so well. thus you see where the question of common sense and using your own judgment comes in. there are always a few things you will have to decide for yourselves. at noon i ate about two handfuls of corn flakes with milk and cream but no sugar, finishing with about four ounces of bread pudding that had a little brown sugar in it. now, in mid-afternoon, as i write this, i am not hungry. tonight i shall eat another dish of corn flakes and some buttered toast and three or perhaps four good-sized apples, i usually eat three or four apples a day. if i want a piece of pie for lunch, i eat it, but i eat nothing else. i live on the plainest of plain foods. apples used to create a lot of gas in my stomach, but now they do not because i chew them to a cream. milk used to make me constipated, but it does not when i chew the cereal with it carefully and eat a number of apples. most nervous people are constipated. but apples are really the salvation of nervous people. if you are constipated, drink, or rather, sip, a glass of hot water half an hour before breakfast, then eat nothing for breakfast but apples; eat two big ones and chew them slowly to a cream. go to stool regularly every morning. this habit is half the cure of constipation. apples, of all things i know, are the finest things for the liver. if you take a patient ill from chronic indigestion, whose stools are clay colored, and put him on a diet of apples, if he chews properly, in less than twenty-four hours the stools will be of the regulation dark brown color, as they should be when the liver is working in a normal, healthful manner. and eating apples will work in exactly the same way with children as with adults. apples, apples, apples! eat them no matter what the price. you remember how good adam found the apple--or at least we presume it was an apple that he found so good--and i can think of no other single thing that would tempt a man to make all the trouble he did. if he had to sin, then i'm for adam every time, for i think had i been in his place and eve had offered me a big juicy red apple, i should have taken it and eaten it. i don't know but that i might even have eaten it without the invitation. i think that adam's great mistake was not so much in eating the apple as in trying to lay the blame on the woman. nobody should ever apologize for having eaten an apple. now, generally speaking, there is one thing a nervous parent--or any other kind of parent for that matter--should never say to a child. never tell him he is nervous. if we realize that our children are the offspring of nervous parents, it is, as i have already suggested, much better for all concerned, for we cannot avoid a danger unless we know what or where the danger is. when we know the child is nervous we should plan carefully, leaving out of his diet all pastries and rich greasy foods, and keep him largely on a vegetarian diet. but, as i have already suggested, we do not need to diet a nervous child as strictly as we do a nervous adult where infinite harm has already been done. give the nervous child meat only a part of the time, and if he goes without eggs it will be all the better for him. i wish from the bottom of my heart that i had never tasted an egg! what a fine thing it would be if we so trained our children that they would never suffer from "nerves"! and usually it could be done. the belief that because nervous parents have broken down their children sooner or later must break down, is our greatest curse. but such a belief is absurd, for if dieting, outdoor exercise, and a few other simple rules are observed, there is no danger that it will happen. to be sure, these rules must be definitely understood and strictly adhered to. if we treat this misfortune in the manner i shall mention later, we can make our lives more successful and infinitely happier than the lives of those who have never learned self-control. for instance, i am far healthier than men all around me who seem to be able to eat three christmas dinners each day. they sit at the table and boast about being "good feeders," then later they come to me for pills, saying, "there is nothing the matter with me, doctor, but i thought i had better take a little medicine so i won't get ill." but they don't fool me. i know exactly what is the matter with them. they are so full of pork they can't think. to tell the truth, we people who have suffered from a nervous breakdown or some illness akin to it, and have learned that we must eat right or die, are of all people the most fortunate. every now and then i hear some good old sister, with a face like a full moon and jowls like a bloodhound, say, as she finishes her third piece of mince pie,--her waist line having extended accordingly,--"isn't it too bad about poor brother jones! he looks so terribly thin! they say he has fallen away from one hundred and sixty pounds to only a hundred and fifty. and they do say he can't eat meat and eggs at all! the poor man!" but the real facts of the case are that brother jones is able to walk ten miles any day, and the possibility is that in the not distant future he will read in his morning paper that sister sue portly has been operated on for gall stones and the number reported is almost unbelievable, about three hundred, in fact. and so, all the time sister portly was feeling sorry for lithe, energetic brother jones, she was a walking stone quarry, as it were, and yet didn't know it. so don't worry because you have to diet or because after reading these lines you determine that you must begin to diet. for, whoever you are, and wherever you may be, you belong to a most fortunate class of people. and now i wish to say some things about what nervous people should do besides dieting, and especially do i wish to say these things to those now suffering from a nervous breakdown. much of it at least will apply to children of nervous parentage. you will observe as you go along that i keep mentioning "these children." i do so always with the thought in mind that there is absolutely no need for them ever to break down if these common sense rules are followed. i take it that not any one of us or a number of us, but that all of us love our children more than we love ourselves. admitting the truth of this, then we should all be interested in this system for them as well as for ourselves, for as their nerves are so shall their success be. iv. value of outdoor life and exercise "better to hunt in fields for health unbought. the wise for cure on exercise depend; god never made his work for man to mend." --dryden people in this country are now beginning to get away from the idea that a man or woman who is past sixty is getting "old." when the rev. john wesley, the itinerant preacher and author, was eighty-eight years old--please note the eighty-eight--he walked six miles to keep a preaching appointment. when asked if the walk tired him, he laughed and said: "why, no! not at all! the only difference i can see in my endurance now and when i was twenty is that i cannot run quite so fast." i know there are calamity-howlers who say: "oh, well, some people are born to success and long life and some are not!" the individual who permits himself to get into that frame of mind is doomed and no one can help him. such reasoning is of course all nonsense. john wesley was always a spare eater. yet he lived an active outdoor life, often traveling forty and even sixty miles a day on horseback. he never failed to keep an appointment on account of the weather. and he was a tireless worker, often preaching four and five times a day. at the same time he read and wrote every spare moment, turning out a large amount of literary work. dr. eliot, ex-president of harvard college, a constant writer and speaker, and among the greatest of american educators--now nearer 90 than 80 years of age--is also a moderate eater. he says, "i have always eaten moderately of simple food in great variety. this practice is probably the result, first, of a natural tendency, and then of confirmed habit and much experience under varying conditions of work and play. from much observation of eating habits of other people, both the young and the mature, i am convinced that moderation, simplicity, and variety in eating are more important than any other bodily habit towards maintaining good health, power of work, and, barring accidents, attaining to enjoyable old age." it is interesting to note what that eminent lawyer, legislator, and orator, chauncey m. depew, had to say on the occasion of his eighty-seventh birthday about a simple diet and reaching the century mark. "the true philosophy of life is this: the more you like a thing the more reason there is for giving it up if you find it is not good for you. if you treat nature properly, nature will adjust herself to you. "my diet is very simple. i have the same breakfast every day in the year, and it consists of an orange, one four-minute egg, one half of a corn muffin, and a cup of coffee which is mainly hot milk. i have this at half past eight. my hour of rising is seven every morning. "for luncheon i partake principally of vegetables, with no meat, and a glass of water. this is at one o'clock. at dinner i skip most of the courses and enjoy small portions of vegetables, fish, and fowl. i never eat between meals and consume now less than half i did at fifty." the vigor and long life of bishop fallows of chicago are mainly due to his living and mental habits and to his simple diet. he is well over 85 years of age, but few men of three-score years can do as much work, the year round. there are two or three sermons and several public addresses each week, and the work of a large parish--from marriages and christenings to funerals and parish visitings--which is never slighted. an active grand army man and civil war veteran, he is asked to address countless military and patriotic gatherings, and his energy seems as tireless as his spirit is willing. his ability to meet these demands can be traced back to simple living and simple eating. the bishop is temperate in all things, and refuses to worry. he neither drinks nor smokes. in regard to his diet he says, "i eat very little meat, but take plenty of fruit, cereals and vegetables. i take regularly before breakfast a cup of hot grape juice. i use it frequently at other times. i take buttermilk daily." night and morning he takes simple physical exercises, and always walks at least a couple of miles each day. the bishop's ancestors were long-lived. his great grandfather lived to be 96; his grandfather, 91; his eldest brother, 93. his father's death from a fall occurred at the age of 81. he has a brother who is 92. this in itself is evidence that he comes of a family in which right living--which means simple living--has prevailed until its effects have shown in each succeeding generation. the world-renowned american inventor, thomas a. edison, now in his 75th year, has today a mind as brilliant and ingenious, and a skill as remarkable for inventing things that are of practical use, as when at 21 he invented his automatic repeater which did so much for telegraphy. and edison is another spare eater. what he ate at the three meals of the day on which he wrote the following letter, is characteristic of the small amount he eats every day in the year. and you will learn that this is true of every man or woman who has lived long and is still doing active brain work. and so, once for all, let us think right about this matter. we get out of ourselves just about what we put into ourselves or do for ourselves in the way of food and exercise. [transcriber's note: the following is the text of a letter from mr. edison that was included as an illustration in the book.] from the laboratory of thomas a. edison, orange, n.j. march 2, 1921. dr. thomas clark hinkle cawker city, kansas. dear sir: your letter of february 25th was received. my food for the one day on which your letter was received, was as follows: breakfast cup coffee 1/2 milk, 1/2 coffee. two pieces toast, 2-1/2" ã� 4", 1/4" thick. another piece toast with two small sardines on it. midday meal glass milk. two pieces of dry toast. evening meal two glasses milk. three pieces very thin dry toast. small piece steak, 1-1/2" wide, 3/8" thick, 3" long. small baked potato. one piece nut chocolate. yours very truly, thos a edison [transcriber's note: this additional note was handwritten on the typewritten letter being reproduced in this section.] weight 185 lbs can diminish this diet without loss of weight e [transcriber's note: end of letter.] most people do not take enough systematic outdoor exercise. and exercise, i would have you understand, is another essential in the cure of one who has "nerves." but i am quite sure that a lot of bad advice has been given women sufferers along this line. i find that as a rule, women make better progress, at least at first, with complete rest or as much rest as they can possibly get. i have seen great harm come from telling a woman afflicted with "the mysterious disease"--as it is often called--to take long walks. i am always extremely careful about telling such a woman to indulge in vigorous exercise. some women, of course, are much stronger than others. my advice to a woman is to walk in the open air unless she is so ill she cannot walk at all without becoming very weak. and here again each person must use common sense and decide the matter herself. but no person with a nervous breakdown should ever work at any task or take any kind of exercise to the point of exhaustion. i well remember a man who came to me some years ago suffering from this malady. he had been trying to get well by doing heavy stunts in a gymnasium. he was very muscular, in fact he was an athlete, and was still under twenty-five years of age. his cheeks were ruddy, and to the ordinary observer he appeared to be in the pink of condition. but he had that peculiar expression of the eyes that flashed his story to me as plainly as if blazoned forth by the letters of an electric sign. i told him at once that he could never hope to cure his nerves by such violent exercises. and right here let me advise men in this condition not to run. i receive many letters of inquiry from young men with broken-down nerves who tell me they are taking long walks and finishing with a run. to all such i say: do not run. i know all about it for i have tried it. i was on my university football team. and all my life i have been fond of athletics. i am still fond of this kind of life and always expect to be, but exercise is frequently overdone by nervous people. usually, the physically strong man who breaks down with "nerves" thinks at once of physical training. but strange as it may seem, you can make such a man's muscles as hard as iron but that alone will not cure him. and it is true that many people in this condition do not seem nervous for they are not at all shaky, as some think an individual should be if he is the victim of a nervous breakdown. i well remember that one day when at my worst i could not work nor concentrate my mind on anything. i chanced to be in topeka, kansas, and passed a shooting gallery. i was a good rifle shot and i had been taking long walks and shooting kansas jack rabbits. i went in, picked up one of the rifles, and started firing at the biggest target. i rang the bell twice on that target in succession, and then aimed at the finest target there and rang the bell twice in succession on that. the proprietor was very much surprised, saying it was remarkably good shooting; and yet i was down and out with "nerves." i have seen many athletes who, to the untrained observer, looked well, but who in reality were nervous wrecks. outdoor exercise alone will not cure such people, or if seemingly it does--and this is important--sooner or later the individual is sure to go down again. you have first to remove the cause, and that is largely wrong diet. now of course it is only reasonable to say that if such an individual does not get out of doors at all he cannot get well. that is one trouble with many of our women today. they will go on a diet and stick to it, but they will not get out of doors. if they do go out, they ride a little distance in a street car or in an automobile to do some shopping. or they go to a store and spend a good deal of time there--indoors, mind you--and then are whirled home again. some of them seem to think that is taking outdoor exercise, but of course it is not. so many times they have said to me, "why, i do get out!" yes, they do get out, but they immediately go indoors again. the nervous individual, unless the collapse is so severe that the first few weeks must be spent in bed, should get out of doors at least three or four hours a day, every day in the week. this is a general rule that should be observed by everyone. it takes genuine courage, i know, for a man or woman to spend this much time out of doors. and i know that those who are compelled to work for a living cannot take three hours all at one time. but labor conditions in this country are such that i am sure the vast majority of our people could spend this much time outdoors in wholesome recreation if they would make up their mind to do so. and remember this: after the nervous person is cured he should never let anything prevent him from continuing such outdoor exercise. i am constantly trying to make this point--when you get well you should stay well. one breakdown is bad enough; don't have another. and you will not have another if you will change the habits of a lifetime as you are advised to do. among farmers there are many, the offspring of nervous parents with bad eating habits, who suffer from nervous breakdowns. so you see exercise out of doors alone will not cure such cases. sometimes a farmer will tell me he fears to give up eating meat because he will grow weak as a result. but just here i wish to call your attention to the fact that there are nations that have for ages lived on this lacto-vegetarian diet. i myself have not eaten meat or eggs for ten years. at least i have not eaten them except the few times mentioned. and every time i did break the rule i was harmed far more than i was benefited. i am very sure the farmer who chooses this lacto-vegetarian diet will thrive on it. members of our profession discovered not very long ago that at an advanced age the peasants of bulgaria are a wonderfully preserved people both mentally and physically. foolishly a great number of the profession immediately jumped to the conclusion that buttermilk alone did the miracle for these people. the drinking of buttermilk became such a fad that some of the largest of our physicians' supply houses began and are still making "buttermilk tablets." and physicians, many of them, are credulous enough to prescribe them. they might just as well prescribe chalk. while buttermilk tablets are harmless, they are of no benefit whatever. how easily fooled people--physicians included--may be! bulgarian peasants are strong and rugged and live to a great age not because they drink buttermilk, but because they live on milk and fruits and vegetables and stay out of doors. buttermilk is a good healthful drink, but it is only a minor reason for the health and strength of the bulgarian peasant. now, really, could you think of anything more absurd than to prescribe buttermilk or buttermilk tablets as the fountain of youth when the patient is breaking all the laws of health, as most buttermilk laymen and physicians are doing? it seems almost impossible that people--physicians in particular--should for a moment believe such things. but they do. barnum said there was a "sucker" born every minute, and this certainly seems to be true. no, there is no royal road to health. the buttermilk-tablet route will not take you there. if you will live out of doors as bulgarian peasants do, and if you will eat as they do,--as man is expected to eat,--you will live just as long as they do, and you will get a great deal more out of life and be much more helpful to others. when the "time" comes round for your next buttermilk tablet, do not take it. instead, do as those peasants do--leave off eating meat and take a two-hour walk in the sunshine. then when nine o'clock comes, like the bulgarian, go to bed and stay there until morning. if the person afflicted with "nerves" expects to get well and stay well, he must go to bed at an early hour and get eight or nine hours of sleep not only some nights but every night in the week. when one begins dieting and taking outdoor exercise he should go to bed regularly at an early hour even though he has not been sleeping well. no matter how many sleepless nights he has experienced before beginning this regime, he should retire early just the same, because, sooner or later, sleep will come and the relaxed body is resting even if the individual does not sleep. now i have been through all this lying awake at night, so i know from experience that it is best to go to bed early and at a regular hour. if you can, you should sleep nine hours. nervous people need more sleep than others. sleep is a better restorer of nerves than anything else we can try. i do not believe that ten or even eleven hours' sleep would be harmful to a nervous adult, because very often i have seen such a person benefited by it. children should have all the sleep they want up to ten or twelve hours. but after a child has wakened in the morning he should be permitted to get up. it is not good for him to lie in bed after he wishes to rise, for nature is calling him to get up and exercise. the nervous individual not only should exercise systematically out of doors but he should play some game. you remember when we were children how much we loved to play? well, to give up play when we grow up is all nonsense. and just because people quit playing is the reason they have wrinkles and frowns. did you ever notice how often people laugh when at play? there is something about play that compels one to laugh. and what all people need, nervous people and others as well, is to get into the habit of laughing more. and it is not hard to find something to play. i like to play at basket ball with a child, and i can enjoy tossing a ball for an hour if the child will stick to the game that long. playing basket ball in the open air on a sunshiny day is one of the very finest exercises in the world. if you are suffering from "nerves" and are able to be out of doors at all,--i mean if you are well enough to be out, and at least nine out of ten sufferers are,--get a basket ball and get some one to play with you. if at first you are poor at catching the ball you will with practice improve. gradually toss the ball a little higher and a little higher until you have difficulty in catching it. any woman or girl can stand this sort of open air exercise. if the weather is cold, no matter; wrap up and play anyway. but enter into the game with spirit. playing the regular game of basket ball is too violent exercise for the nervous person. the victim of "nerves" should always keep in mind that it is mild outdoor exercise that will do him good. tennis is too violent an exercise for people who have had nervous trouble. anyway, there is no use in one's doing anything that will make his heart beat like a trip-hammer. a women can toss a basket ball and laugh and get rosy cheeks and grow younger and prettier as easily as when playing tennis. golf is also good exercise, but a large number of people who work for a living and suffer from "nerves" would have little chance for exercise if golf were all that could be offered them. furthermore golf is practically only a summer game, and an individual belonging to the pre-nervous class needs outdoor exercise every day in the year. but golf is excellent exercise, and there is nothing better if one has the time to give to it and has access to links. bicycling is splendid exercise for nervous people, but automobiles are so numerous that it is now considered almost dangerous to ride a wheel on any of our main traveled roads. mountain climbing, i believe, is not to be recommended for most people suffering from "nerves." i have known such people to go to colorado and spend some time climbing mountains, and then come back much worse than when they went away. my advice to the nervous person who goes to the mountains is to be out of doors all the time he can, but to take things easy. it would be better for such a person to walk about slowly on the level ground through some of the towns or along the foothills. let leisure be your watchword in a hill country. i know i injured my nerves out in colorado one summer because i was ill advised. mountain air is good for you, but the mountains will do you more good if you simply look at them. if you think you must go to the top, take a burro. you will find that the burro will give you a lesson in how to do things in a leisurely way. do not get out of patience with him and whip him. remember that the burro is smarter than you are in regard to the business of mountain climbing. he has never had a nervous breakdown, and if you will let him have his own way he never will have. it will do you good to let him have his way; he affords a tremendous lesson in patience. patience, that's just what we need, and we need it badly. walking slowly in the open air for two or three hours is the best exercise for man. fortunately, like the water we drink, it is free to the poor as well as the rich. for the nervous man who is able to do it, i know of nothing better to build up muscles and keep the liver and other internal organs in good shape than sawing wood. don't scorn this sort of exercise because you have been told that the ex-kaiser is taking it. that is not to be laid up against the wood or the exercise, for, quite fortunately, the wood does not care who saws it. get some wood, then, and a buck saw, and saw wood for your own benefit. you can do this morning and evening. wood sawing brings into play every muscle in the body, and the exercise is just enough to make a man comfortably tired without doing him harm. many people who go to sanitariums for a cure pay from fifty to seventy-five dollars per week for the privilege of sawing wood, and you can take this exercise just as well and at considerably less expense at home, sawing your own wood instead of that of the sanitarium. another splendid diversion for a man with "nerves," if he can have it, is a small workshop where he can make just any old thing out of boards and nails. if one is apt in this line, he can make things that will interest children. this sort of work requires a certain kind of concentration that is most excellent for the nervous sufferer. this suggestion would of course apply to a woman, too, if she cared to try such an experiment. sewing, and especially fine needlework, is very trying to a woman's nerves, and if she has broken down under that kind of work she should quit it and do something else. if she has to make her living in that way, she of all people should observe the outdoor rules as well as rules for dieting. i am sure nervous people profit by frequenting all possible outdoor games. if a number of people afflicted with "nerves" could get together and take daily walks and at the same time determine that their conversation should always have a humorous slant, it would help all of them wonderfully. riding in an automobile is beneficial if the machine is driven slowly and the patient is kept out of doors from three to four hours. but the fast driving that is generally done is bad for these people. they come back from a ride worse than when they started. it may be set down as a general rule that any form of outdoor exercise or play is good for the nervous person if it is not violent. nervous people should, if possible, take a vacation once a year and get into new surroundings. i am certain, however, that it does not make any difference where one lives. a man is just as likely to have a breakdown in one part of the world as another. while on these vacations he should stick to his rules just as rigidly as when he is at home. i have had letters from people in canada and from others in florida who have suffered nervous breakdowns. in california some go to pieces. i have had many letters from people living there who have broken down. people also break down in colorado and in new york; in fact, in every state in the union. climate does not seem to make any difference so far as this trouble is concerned, with the exception that in high altitudes i have observed nervous people are inclined to be more restless than elsewhere. some years ago i went up pike's peak, to the summit house. i went to bed and spent the night there, but i do not say i slept, for in reality i slept only about half an hour. i was not at all sick at the stomach, as so many are who climb up there; i had prevented this by eating a very light breakfast and chewing my food to a cream. but i was extremely nervous. i have found a great many other nervous people who do not feel quite right when in a high altitude. as a general rule, sea level is as good a place as a nervous individual can find to live. but people break down there, too. the diet, you see, is the big thing. and when i say "diet" i mean the way food is eaten and the amount eaten quite as much as i do the kind of food eaten. and once more let me say, systematic outdoor exercise also counts, and you can't keep fit if you exercise only one, two, or three days a week. some people who take long walks in the country on sunday think that will suffice. but it will not. you must have exercise every day and must have some play along with it. gymnasium work is of very little value as compared to outdoor exercise. in the summertime, gardening is a splendid form of exercise. and so is the care of a small flock of chickens, which is possible for those living in the smaller towns. it is always better, when taking outdoor exercise, to have something definite to do. when walking it is a good plan, if you can, to have some definite place to go. and if you have an agreeable companion to keep up a rapid-fire talk, that will help also. all these things are mentally stimulating. then, if possible, sleep the year round on a sleeping porch. if you don't possess a porch, then, have all the windows in your sleeping room wide open day and night. if for a time you have to take physic, it is best to take some hot mineral water half an hour before breakfast. but adhering to dieting and exercise, and eating enough apples, usually overcomes constipation. now, there are some things about which a person must use his own good judgment. for instance, if you have any bad teeth you should at once go to a good dentist and have them attended to. nobody with bad teeth can have good health. again, if your tonsils have become mere pus sacs you will have to go to a good nose and throat specialist and have them removed before you can expect to have good health. this, however, applies to all people, whether nervous or not. the same thing is true with regard to your eyes. if you are suffering from eye strain because you need glasses, you cannot hope to get well of "nerves" until your eyes are properly fitted to glasses by some reliable eye specialist. these are things that each individual must discover and do for himself. he should consult a dentist, an oculist, an aurist, or other specialist according to his particular need. v. effect of right living on worry and unhappiness "neither melancholy nor any other affection of the mind can hurt bodies governed with temperance and regularity." --cornaro a very sad thing about some nervous people is the fact that in their lives there are domestic or other troubles which no physician can overcome. some of them live in depressing surroundings, but for all these there is hope. there is no doubt that if we can restore the brain to a perfectly normal, healthful state the human being can bear more suffering than when the brain is affected. perhaps when speaking of the spirit we had better call it that, rather than the brain, for that mysterious something we call spirit does make its home in the brain of man. this has been proven scientifically. so then, in this life the temple of the spirit, or soul, does affect the mind. and when i say this life, i take the opportunity to say here that i not only believe in the immortality of the soul, but now, at 45, i am as certain of it as i am of my own existence. but for some reason--although as yet no one understands why it should do so--when this temple in which the spirit dwells is out of condition, it affects the soul or spirit. so, you see, if we can make the physical man or woman well, we most certainly can help the spirit that dwells within the body. and so i recommend dieting, temperance in eating, and the careful chewing of food to all those sufferers who unfortunately live in depressing surroundings and cannot get away from them. when referring to the many pitiful letters i have received from poor human beings thus situated, i realize that i am treading on sacred ground. such things are written, of course, to a physician in confidence and the confidence must therefore be forever sacred. i have not only had letters from these unfortunate people, but have repeatedly come in contact with many of them in their every day life. i know well what added suffering such conditions bring to them. i know of nothing in this world more pitiful than a noble, high-spirited, ambitious woman, pure and clean of heart, who marries a man and becomes the mother of his children and is then condemned to live the life of a mere animal. and all too frequently the opposite also obtains. sometimes a man of high, pure purpose finds that he has chosen as the mother of his children a coarse, sensual woman. now why in the world were these two people attracted to each other? this is one of life's biggest puzzles to those who have thought much along this line. in many instances extreme youth is the reason given. while youth is mating time, it also is the time of bad judgment. thousands of young people have made this dreadful mistake simply because they married too young. on the other hand, youth is not altogether to blame. when people, young or old, are courting, each individual endeavors to appear at his or her best before the other. without being actually aware of it, under such circumstances both man and woman are doing all that lies in their power to deceive one another. if people would do their courting in everyday clothes, and if the girl would go about her housework while the man looked on, or better still, if he helped her with it for one or two years, they would undoubtedly become better acquainted. but, after all, except, perhaps, in unusual cases, there is absolutely nothing by which people know that they are going to be properly mated. if a man with a tendency to neurasthenia breaks down and is tied to a nagging wife, that is usually the last straw in the way of his recovery. this is just as true of the woman who breaks down and has a nagging husband. there are, i regret to say, thousands of such cases all over the country. on the other hand i have had a man come to me and say that he was willing to do anything on earth to aid his wife, but he could not get her to diet or even to make a serious attempt to get well. i am always tremendously sorry for such a man because he has a mighty heavy burden to bear. such a wife should try to get well as much for the man's sake as for her own. she should understand that she is needlessly torturing the one best friend she has on earth. a woman of this kind should remember that, no matter how much she may suffer, she is hopelessly selfish if she will not do all in her power to diet and to obey other necessary rules that will enable her to get rid of the malady. sometimes when a physician puts this before her kindly but firmly it results in her making a beginning and by and by getting well. i have seen this happen many times. and i wish to say right here that while i believe i was born with some natural tact, yet if i had not gone through all this horrible suffering myself i should not, i know, be able to say the things that would induce these people to do that which it is their duty to do. and here is one big difficulty i have always had to contend with. some of these people have tried so many so-called nonsense cures--eating buttermilk tablets, for instance--and have had no benefit from them, that they are unwilling to try the one and only thing that will cure them--the thing that will cure them as sure as the sun shines. i wonder why it is that since the time of christ people are always looking for a sensational or miraculous cure. our life and everything pertaining to it is miracle enough, if we only had the sense to see it. the woman or the man with "nerves" is not going to get well eating buttermilk tablets or taking patent dope while lying on a couch and shut in a house. you must bestir yourself. you must get out of doors, and above all, you must eat right. today thousands of these people are languishing in hospitals and sanitariums, and most of them will come out only to go back again and again. the institutional treatment is good for the beginning of the cure, but if an individual with "nerves" is going to get well and stay well he must change his lifelong habits. and i want to say again, that any person, man or woman, in the midst of depressing conditions can triumph over them if he will eat as he should and live as he should. there is something about the human soul, if it is pure and fine, and if proper attention is given to right living, that will enable a person to meet great sorrow and triumph over it. in fact, no amount of sorrow can defeat a person who keeps his heart and body right. and i would have you all realize that there is something far more to us than mere bones and veins and nerves. i know the terrible tendency of the one with "nerves" to get angry. but lay fast hold of yourself. fight anger as you would poison, because in reality it is poison to your nerves. anger will hurt you; it will hurt anybody. but no matter how hard you find it at first, get control of your temper. if you succeed in doing this in a year you will have won one of the greatest victories man can win in this world. i would rather meet a so-called plain man who has perfect control over his physical and mental faculties, and sit and talk quietly with him, than to meet the prime minister of england or the president of the united states if either lacked this control. for i say to you that no matter what others may say, the true measure of success does not rest in the position you occupy but in your having complete control of yourself. if you are to gain this control it means that each day you are confronted by a mighty big task, but if finally successful, you will have accomplished the greatest thing a man can do in this life. now, here is something for you to take hold of, you who all these years have believed that your life ambition has been thwarted. but your ambition, let me tell you, has not been thwarted. perhaps you have not done just what you wanted to do. but it's quite possible that you had no business trying to do that special thing anyway. most of us, i find, can be greatly mistaken about what we think we want to do. at any rate, we can never be happy unless we gain entire control of ourselves. this is something the person afflicted with "nerves" most certainly can do, and he can use this terrible "thing" as i myself and thousands of others have used it as a ladder to climb to the sunlit peaks where worry and clouds and storms cannot trouble. and, after all, no matter who we are, no matter how poor or how rich we are, and no matter where we live, life holds about the same general possibilities for all of us. i mean by this that life affords to all the same opportunities for real happiness. i know very well that there are those who will be quite unwilling to grant this, but it is as true as the life we live. many people in this old world still hold the notion that those who roll in wealth are the happy ones. but i say to you this notion is all wrong, and from knowledge gained through experience i know that in their hearts many of these wealthy people are dissatisfied and not one whit happier than you are. the most restless people, the most unhappy people, and the most thoroughly dissatisfied people that i have ever met have been people who had everything that riches could give them. andrew carnegie said he had noticed that after a man had accumulated a million dollars smiles were seldom seen on his face. i cannot understand why people insist on going through life making themselves and all those they really love miserable just because they do not happen to have riches. and a great many high-strung sensitive men are utterly cast down because they have failed to acquire wealth by the time they are forty-five or fifty years of age. i wish i could make all such poor, afflicted people see what goes to make up happiness and learn the only way to be happy. in order to get well the thing we have to do is to follow nature's simple rules--rules our creator gave to us. we must get control not only of our appetites but of all such passions as anger, hate, and envy, which poison our bodies. and let us also cast suspicion out of our minds. this is a good rule to observe: never suspect folks. it is useless, anyway, for by and by what they are or what they do is always bound to come to the surface. by gaining perfect control over yourself--and most certainly to do so is worth every effort you may make--you will also gain patience, and that is, i think, one of the crowning virtues. sometimes i think it the greatest of all virtues. certainly it stands very high in the perfecting of character. to the sufferer with "nerves" i would say: have the courage to believe that you are going to get well. then you can do it. no matter how depressing or discouraging your surroundings, do the very best you can every day. then, no matter what your ideas of success may have been, you are really succeeding wonderfully! see that you keep right on doing it! if you are a mother and have children, live for them. or if you are a father and have children, and have met with disappointments, live for those children! do everything in your power to make them happy, high of heart, and gallant of soul. do not live for yourself, live for your children. if you have no children of your own, look about and get interested in some other person's children. you will find a lot of children all around you--blessed little beings--that you can help to make happy. get your mind off yourself and your troubles and on the children of this world, and keep it there. when you were a child no doubt you had many happy days. some of us had a very happy childhood, while others may have been denied what their hearts desired. but if we did not have a happy childhood that is all the more reason why we should be glad to help some other little ones have a happy one. more and more each year i live i come to believe that it depends entirely upon grown people whether in this world children are happy or not happy. if you had a happy childhood--and most people had--do you not recall the glorious times you had? i know you do, for we all do. and i know, too, how much people affected with nerves dwell on those memories, and how much they wish they might go back to those blessed days when the sun was always shining and the birds were always singing and the streams always beckoning them to play along their sands. do you realize that you can live in those days again? i do, and i go back and dwell in them more and more the older i get. i do not mean that i am not looking forward, for i am, tremendously. how stupid we poor miserable creatures of this world become after we leave our childhood days behind us! we really should never lose sight of them. i have said that the person afflicted with "nerves" should not run. i did not quite mean all that implies. after such a man has recovered, if he has a good heart, he should run a little. i run; i can't help it. i feel so good i have to run a little now and then to work off steam. but you know very well when most people see a man running they at once think a house is afire somewhere. it is almost unbelievable that we should actually surround ourselves with so many utterly senseless customs that tend to nothing but misery and unhappiness. we should dress for comfort, and we should have the courage to live in a youthful world where all may be happy. "if the blind lead the blind," so the bible tells us, "both shall fall into the ditch." we need so to live and act that we shall not fail to be happy. happiness really is what everybody is chasing, but how very far away from it most people are getting! go back to the memories of your childhood. be with children and play with them all you possibly can. if you are a mother, begin this very day to exercise more patience with your children, recalling over and over again that when you were a child you were just as they are. and remember, for it is only too true, that the day is fast coming when your little boy will no longer be a little boy, he will be a man, and will have gone away from you. then many times you will wish him back, and you will look back on those days when you thought your nerves were being ruined, and feel a great swelling in your breast, and breathing a sigh, whisper to yourself, "dear god, i hope i did all i ought to have done for him while he was little." i know that any one can live with children and find happiness in being one with them, and i know of no better thing to do. after we have hold of ourselves with a firm grip we should endeavor to do this. i have had people suffering with "nerves" tell me they had lost a little boy or a little girl, and that it seems impossible to get over this loss. i cannot tell you how much i long to help such people. but i always urge them to go right on playing with other children and to remember, for to me it is certain truth, that they will meet that little child again. there should be nothing to grieve about in such a loss. to find compensation, the one who has had such a grief has only to keep on playing the part of a true man or true woman. childhood with all its pains and pleasures is everywhere about us. and childhood is only the beginning of immortality. late one night, a number of years ago, i was sitting in a little restaurant in a western town, and was feeling very lonely and miserable. sorrow weighed heavily upon me that night and the world never seemed blacker, yet i think my belief in the immortality of the soul had never been more certain. i looked up and high on the smoke-stained wall hung a painted picture of an old-time ship with many sails set. this painting pictured the ship sailing through the darkness of night. but through the dark, seemingly restless clouds the moon gleamed brightly on the white canvas of the sails. i had never before been so powerfully impressed by any picture. it seemed fairly to speak to me. i took an envelope from my pocket and set down the verses given here. these verses were afterwards published in one or two metropolitan papers. mr. james bryce, then english ambassador at washington, saw them and wrote me a beautiful letter about them, in which he said, "your little poem 'the last journey' attracts me very much." you see he was beginning to grow old, and i knew that was the reason these lines of mine had made an appeal to him. not very long after this i also had a letter about the verses from dr. osler, then regius professor of medicine at oxford. in it he said, "i have read your little poem 'the last journey' with unusual interest." and again i knew why. you see, it does not matter very much what our rank or our station here, no matter whether a human being is a king or what his station in life may be, he still is a human being. we are all reaching out after the same great thing. the fine thing about the sentiment of these little verses is that although you wish to and may not believe it, it is coming true anyway. ---------------------------------------------------------------------- the last journey one night when in a youthful dream, i saw a moonlit sea, and sailing o'er its dark expanse, a ship of mystery. the lonely traveler seemed to be on some great mission bound, as o'er the darkened waters it sailed without a sound. long years have passed; old age has come: the fire of life is low. again i think of that strange dream of youth so long ago. and in the ship that swiftly sailed that silent moonlit sea, i seem to see a storm-tossed soul bound for eternity. now to my mind this sweet dream comes, a peaceful memory, for soon i'll be a youth again, with immortality! goddess of the moon _a complete planet novel_ by john murray reynolds death hid behind a smile in the white-and-gold city of gral-thala. gibson, earth-spy off the derelict strathoship, well knew his captive-fate. but if he died, then the good green planet perished from the gray death.... if he died, then died diana, fair goddess of the moon. [transcriber's note: this etext was produced from planet stories spring 1940. extensive research did not uncover any evidence that the u.s. copyright on this publication was renewed.] the tokyo-to-new york stratholiner swept down toward the manhattan municipal airport early on a winter evening, with the port-holes gleaming all along the 300-foot length of her polished steel body. rockets cut off well above the city in accordance with the strict american traffic regulations, she came down with half a dozen big props spinning under the drive of her powerful diesel auxiliaries. a dozen whirling helicopters had been upthrust to take the strain. she came down to a city that lay murmurous and uneasy under the greatest threat that mankind had ever faced--the threat of the gray death! a band was playing in the liner's saloon, and passengers in the smoking-room were hurriedly gulping down the last of their drinks. there was a forced and unnatural gaiety on board. most of the passengers had taken more than a few drinks on the way across from tokyo--for the news of the spread of the gray death was ominous. it is hard to retain peace of mind when a strange new epidemic rages unchecked from alaska to cape horn and from nova zembla to new zealand. men and women were dying like flies, and all the medical science of this twenty-fourth century seemed helpless before the deadly plague. it was the steady vibration of the diesels that brought larry gibson back to an awareness of his surroundings. their resonant hum was distinctly different from the pounding blast of the rockets, and any experienced stratho-pilot could tell the difference in a second. larry tossed off the last of his drink and wiped his mouth with the back of an unsteady hand. then he pushed back his chair and stood up, swaying as he tried to hold his balance on the slightly tilted floor of the descending liner. a man at the next table glanced curiously up at him. "guess we're landing, friend," he said. "y'know, they say that there are a thousand deaths a day here in new york city now. they're digging graves in the cemeteries with electric shovels, i understand." "life," said larry with alcoholic gravity, "is cheap. too cheap. one hundred lives equals a man's career. it's all been worked out mathematically. good evening." larry left the third-class bar where he had been sitting, and walked slowly along the corridor. mechanically he turned the collar of his frayed coat up around his neck and pulled the brim of his wide hat well down over his eyes. there was always the possibility that someone would recognize him, and in these past months he had learned to keep in the shadowy byways of life. the time would come when men would forget that an unlucky person named larry gibson had ever existed, but in this year 2332 there were still plenty of people who would recognize his face. * * * * * gibson was not traveling in the first-class section of the big liner, in those luxurious quarters built into the giant wings to which his rank had once given him free entry. back in the days when he had been chief pilot of all the strathofleet he could ride there as a matter of course. now he could not afford it. he could not even afford the second-class accommodations amidships. instead, he rode in the third-class quarters back in the tail. when a man knows that he has no possible chance of getting another job, he has to hoard the money he has saved up. the giant airliner came down to an easy landing, and rolled across the field on her big wheels. the lights of the airport burned as brightly as ever, but anyone accustomed to new york could tell that there was something wrong. there were no crowds of spectators at all, and the few people who met the incoming travelers looked harassed and nervous. even the airport attendants went about their business in a listless and somehow furtive manner. it had been ten days ago that the blight first struck a peaceful world that believed it had at last made life safe and pleasant for its inhabitants. a few peasants in honan province in china had taken convulsions and died while their skins turned a peculiar silver gray. within twenty-four hours similar deaths were reported from points as widely separated as bergen, norway and santos in brazil. since then the strange new epidemic had raged unchecked. all the medical and financial resources of the confederated nations of earth had been thrown into the fight without effect. the gray death struck quickly, men and women alike dying within six hours of the appearance of the first tell-tale patches of silver on their skin. the population had not yet started to panic, except in a few isolated instances, but the nerves of all men were ragged and jumpy from the strain. standing in the crowd of third-class passengers that had just alighted from the liner, larry gibson heard two of the airport attendants talking. "he claims he's going to take that old rocket-ship to the moon!" one of them said, and his companion chuckled. "crazy, all right." "guess he is. but what i'm wondering is how he got a crew to go along with him." "have you seen them? they're the damnedest bunch of derelicts i ever saw." for a moment larry was tempted to ask the attendant for the name of the vessel they were discussing. it sounded like the one place where a disgraced and black-listed officer might get a berth. then he shrugged and turned away. nothing mattered very much, any more. ii the alighted passengers strayed slowly across toward the glass and chromium entrance to the administration building. the landing lights were cut off, and the airport became a deep pool of quiet shadow in the midst of the towering ramparts of new york's buildings. most of the structures were two hundred stories high in this queenly city that had been built on the site of the old one destroyed in the final world war of 2132. then a woman began to scream. she was standing in the glow of light from the administration building, holding out a shaking hand that was already turning silver on the back. people hurriedly backed away from her. she was already in convulsions before the white-garbed attendants from the airport hospital could get her under shelter. a man swore tonelessly, and people kept far apart as they hurried from the field. the gray death had struck again! most of the passengers took elevators to the upper floors. there they boarded monorail trains that took them to the part of the city where they were bound. or, if they happened to live near the airport, they simply went along one of the glass-enclosed cross-walks that clung to the outside of the buildings and bridged the streets in graceful curves. larry gibson did not go into the administration building at all. there would be too many people who might know him, and he dreaded their sneering smiles of recognition. he went out a small gate at the side of the airport, a gate that led to the tenth-floor level. the lower parts of new york's towering buildings formed the zone of factories and warehouses. there were few lights here at this hour, and the cross-walk was nearly deserted. larry was looking for a cheap place to stay, to conserve his dwindling resources. it wasn't that larry was particular about the kind of work that he was willing to do. that stage was far behind him! it was simply that, in this simplex and highly organized civilization of the twenty-fourth century, a man couldn't get a job without showing his properly authenticated identity papers. and when a prospective employer saw his papers, it always turned out that there were no vacancies available. there was a hard bitterness in larry gibson's eyes as he trudged away from the airport. after about half a block, larry turned in at a little place called the moorings bar. it was dingy, and smelled of stale beer. most of the customers were night-shift factory employees, waterfront loafers, and the crews of the water-borne ships that still crawled sluggishly across the ocean with those bulky and cheap commodities that the airliners did not care to handle. half a dozen roughly clad men leaned on the greasy bar. larry sat down at a corner table and called for a drink. so he was back in new york--the city that had been his home before the stratholiner _pegasus_ fell into the sea with a loss of a hundred lives two years before! larry wondered how long he would stay here. not long. a month, or perhaps six weeks. the latter would be a long time for him to remain in one place nowadays. he had become a wanderer. a rolling stone that gathered neither moss nor worldly goods, nor even much of the peace of mind that he sought. so he passed like a shadow from city to city and from land to land. he made no friends nowadays. larry gibson was still a young man, but there was a cold grimness about his face that did not encourage advances. * * * * * a radio behind the bar had been playing music, but now the sound abruptly ceased and the television screen went blank. then the face of a government announcer appeared on the screen. his voice came from the speaker sharp and clear. "though the toll of the gray death continues to be very heavy, the government of the confederation is pleased to announce to the peoples of earth that the mystery of the disease has been solved. it is found to be a new and malignant form of leprosy, caused by some hitherto unknown germ. it has also been found that the proper use of radium can control the disease, when applied by what doctors call the riesland method. that is the end of this bulletin." the radio returned to playing music. the bald-headed bartender grinned broadly. "maybe we'll have a chance to go on living after all, boys," he said. "i guess that calls for a drink on the house." "aye--the mystery of the gray death is removed!" a deep voice behind larry rumbled with heavy sarcasm. "i could have told them that answer a week ago, if i'd thought the thick-headed fools who run this planet would listen to me! but what they haven't announced is that the riesland method calls for a lot of radium, and all earth's supply is not enough to check this epidemic in time to save the population of the planet!" larry turned around to glance at the speaker. it was a man who sat alone at a table by the wall. he was a very tall man, gaunt and gray-haired with a pointed beard that jutted forward at a pugnacious angle. exceptionally heavy eyebrows gave him a quizzical appearance. his unpressed clothes were badly stained, and rakishly tilted on one side of his head was a slouch hat of a type that had gone out of style many years before. a half-empty bottle of rum stood on the table before him. somehow he gave the impression of having already consumed what liquor was missing from the bottle, and of having every intention of emptying it before leaving his table. well, larry gibson reflected with a sardonic grin, _he_ was no one to criticize a man for a little thing like excessive drinking. his own record in that regard had been pretty lurid for the past two years. just then the other man grasped his bottle firmly in one hand, and his glass in the other, and lurched over to larry's table. "mind if i join you for a bit of conversation, young feller?" he boomed. "rum, more than any other essence of bacchus, is a friendly drink that needs to be shared." larry looked up at him without cordiality. he had been living alone with his bitterness and frustration for so long that he resented any intrusion on his privacy. then he suddenly grinned. there was a reckless and irrational gallantry about this gaunt old man that appealed to some part of his own nature that had now been dormant for a long time. "sure, sit down," he said. "thanks, young feller. my name is crispin gillingwater ripon, and i feel the need of a little company after a hard day trying to recondition a rocket ship with the lousiest collection of shiftless renegades that ever signed on as crew for such a craft." "what ship is that?" larry wanted to know. "the _sky maid_." "never heard of her," larry said thoughtfully and slowly. "you wouldn't! she used to be the _orion_, but she is now renamed and my ship--subject to a matter of a few liens and some faulty hull insulation and a very good chance of never coming back to port again after i start on my voyage. have a drink, young feller!" "the _orion_!" larry exclaimed "why, she was condemned as not air-worthy over a year ago!" "how else do you think i bought her?" ripon grinned. "i'll concede that, if the world had shown a proper appreciation for my varied talents, i'd be a millionaire many times over, but i happen to be almost broke. you appear to be a promising lad, young feller. how about signing on for a trip to the moon?" "so you're the crazy man who is talking of going to the moon," larry grinned. ripon glowered at him from under his heavy brows for a minute, then grinned in return. "be more careful with your language, young feller, or i'll bust this bottle over your head! i may be eccentric, but i'm a lot saner than those pedants who claim the trip can't be made." iii ripon was sprawled back at his ease, a smoldering pipe in one hand and his glass in the other. he was smiling at larry's startled expression, but he seemed to be serious. vague memories were stirring in larry gibson's mind, memories of things he had read and heard in the old days before he became a drifter whose main effort was to avoid thinking at all. crispin gillingwater ripon! he had heard the name before, though it had been in connection with abstract science rather than with practical rocket-ship flying. somehow, his memory of the name was connected with failure, with public derision, and with rumors of outright charlatanism. "i think i've heard of you," he said cautiously. "in that case you have heard no good!" ripon said cheerfully. "i am at present the problem child of the scientific world. the horrible example! a laughing stock for seedy professors and callow students. mention of my name produces hoarse guffaws of mirth in scientific circles at the moment, young feller, but it will be different when i return from my successful trip to the moon. better come along." "why are you going at this time?" "because there are radium salts on the moon, i am convinced. this world hasn't treated me with much respect, young feller, but i've had a good time on it for my sixty-odd years and i'm fond of the old place. i want to make the trip and get back before the gray death wipes out our population--including myself!" "but you can't take a rocket-ship to the moon," larry protested. "professor staunton's attempt proved that thirty years ago." "all it proved was that neither staunton nor his ship were ever heard of again," ripon said calmly. "i knew staunton well. he was a good man, a careful man--but he wasn't crispin gillingwater ripon! i'm making some changes of my own in the _sky maid_; changes that should spell the difference between success and failure." when he looked back at it later, larry had only a hazy recollection of the rest of that evening. the rum got to him. the one thing that did stick in his mind was a snatch of song that he and ripon had sung over and over again, pounding their glasses on the table while the other men in the dingy little barroom stared at them in good-natured derision. "there's only a few of us left, and we never were worth a damn, but i'll follow my vagrant star, that's the kind of a guy i am! (drink it down!) that's the kind of a guy i am!" * * * * * larry gibson awoke the next morning to the sound of many hammers beating on a steel shell. there was also a sharp and comprehensive ache that started at the top of his head, which felt as though someone had been hitting him with the butt of a ray-gun, and spread all down through his body. he groaned and sat up. he lay in a bunk, in a steel-walled cabin. evidently the officers' quarters on some strathoship. across the white painted ceiling, where flakes of red rust were showing through the dirty paint, the word condemned had been stenciled in black. sitting upright on the edge of his bunk, larry momentarily dropped his head in his hands. then he stood up and left the cabin, grinding his teeth at the ceaseless pound of the hammers on the steel shell. at intervals, as larry went slowly down the corridor, he passed the word condemned stenciled on the walls and bulk-heads. when the government inspectors decided that a a rocket-ship was no longer safe for flights through the vast emptiness of the strathosphere, they made the fact very evident! he climbed a ladder to an open manhole, and emerged into the bright sunlight of a winter morning. for an instant he filled his smoke-tainted lungs with deep gulps of fresh air. then he looked about him. he stood atop the red-painted hull of a rocket-ship. it was an old v-39, a type that had been first built some thirty years before and was now obsolete. the weathered paint was badly rust streaked, and the worst spots had been touched up with bright red lead so that they looked like livid scars. the ship was lying in a corner of the airport, and a gang of men were busy at what appeared to be an attempt at general reconditioning. after one look larry didn't think it would do much good. turning forward along the top of the super-structure, larry met a man in a faded blue uniform that bore the two stripes of a second officer. he was a lean, swarthy-faced man with a meticulously pointed mustache that contrasted strangely with his otherwise down-at-the-heels appearance. "morning," he said shortly. "i'm colton, the second officer. guess you're the new first mate." "if so, it's news to me!" larry said grimly. "where's the madman that commands this decrepit craft?" "you'll find the old man in the control room. and if you use your head, you won't speak slightingly of the _sky maid_ in his presence." "when i want your advice i'll ask for it," larry said. colton's eyes blinked momentarily, but then he smiled and larry immediately marked him down as a man to be watched. he didn't trust people who smiled when they were insulted. "suit yourself," colton said as he turned away. crispin gillingwater ripon was bent over a set of strange diagrams spread out on the chart table in the control room. thick smoke swirled from the short pipe clenched in his teeth. his face was deeply lined this morning, and there were wrinkled hollows under his eyes, but he looked up with a broad grin as larry came into the dusty control room. his reckless eyes were bright and cheerful in spite of being bloodshot. * * * * * "cheerio, young feller!" he boomed. "how's the pride of the strathosphere this morning?" "all right," larry said shortly. "it seems that i owe you thanks for a night's lodging. but what's this about my being first mate of this hulk?" "accepting your unspoken apology for having maligned my ship," ripon said severely, "the statement is correct. you signed on last night. i have your signature to prove it--although it's a bit shaky because i had to guide your hand which seemed unable to hold the pen." "do you know who i am?" larry asked grimly. "do i know who you are?" ripon's lean, brown face suddenly crinkled into a smile. "good lord, young feller, you spent two hours last night telling me your life's history while you cried into your beer." "then i can't have told you the whole story." the hang-over, and the fact that he had not had any solid food in nearly twenty-four hours, were making larry slightly dizzy. his voice rose in spite of himself. "i'm larry gibson, black-listed in every airport in the world. 'gibson the murderer,' the newspapers called me. i'm the man who was master of the rocket-liner _pegasus_ when she fell into the south pacific with a loss of a hundred lives. it wasn't really my fault, but the inspectors believed some fools who lied to save their own skins. now, my friend, do you see why i can't sail on even your shaky old craft? i was drummed out of the service, and ever since...." "and ever since you've been going around feeling sorry for yourself!" ripon's voice cut sharply through the mists of larry's bitterness. "hell, young feller, i've been disgraced worse than that more than once. i just don't pay any attention to it. forget it. i need a first officer on this trip, and i believe your story that the disaster wasn't your fault, and there's an end to it! you're coming along." "but i haven't even a license any more." "that doesn't matter. governmental regulations don't apply to a trip to the moon. they don't license a man for what they think is suicide, you know! go ashore and get some breakfast to steady you down. then, when you feel better, come back and i'll go over the details of the trip with you." for a long moment larry stared at ripon. then he began to laugh. "by the lord harry, i think you're crazy!" he said. the gaunt scientist grinned back at him with complete good humor. "better people than you have called me that, young feller," he said cheerfully. "they've been expecting me to get myself killed for years. but crispin gillingwater ripon is still alive and healthy--albeit somewhat battered. follow my star and you'll have plenty of excitement, even though it may get you nothing more than a broken head." iv when larry gibson returned to the ancient and seedy-looking _sky maid_ after a breakfast at a nearby restaurant, he paused to look at the work in progress outside her hull. it was like nothing that he had ever seen before. a network of interlacing wires was being bolted to the outside of the ship's cigar-shaped hull, so that they formed a sort of screen with the strands some two inches apart. other men were busy at caulking rivets and repacking insulation. this last was routine stuff in connection with any attempt to recondition an old vessel for travel in the thin, chill regions of the strathosphere--but he was completely puzzled by the painstaking labor of fastening those criss-crossing wires in place. he found ripon still in the vessel's dusty control room. much of the equipment had been ripped out when the ship was first condemned. the missing articles had been hastily replaced with second-hand equipment which was often of a slightly different pattern from the original, so that the whole room had a makeshift appearance. the lean scientist looked up from the clouds of blue and vile-smelling smoke that swirled upward from his pipe. "well, young feller!" he boomed in his deep voice that could easily carry above the dull roar of rocket motors. "how do you feel now? ready to go to work?" "listen!" larry said. he had intended to be sharp and sarcastic, but he was grinning in spite of himself. it was hard to stay angry with anyone as irresponsibly cheerful as crispin gillingwater ripon. "seriously! you couldn't take the best rocket-ship on earth to the moon, let alone this old derelict. not if you want to come back alive. it's been proven that, by the time you reach the velocity of escape to get away from the earth's attraction, you have a speed too great for our present knowledge of rocket-ship technique to brake in time to prevent disaster...." "_how_ has that been proven?" ripon interrupted, jerking the pipe from between his teeth and pointing the smoking stem at larry as though it were the barrel of a ray-gun. "why--by the two attempts that have been made! you know the story. two hundred years ago, at the time we had the last war on earth, that group of defeated outlaws stole the giant transport _mercury_ and started for the moon and vanished. then, it was only thirty years ago that professor lester staunton made his attempt in the rocket cruiser _orestes_, and he vanished." "you're like all the rest," ripon grumbled. "always jumping to conclusions based on a few scraps of evidence. no man on earth really knows how a rocket-ship would behave in interplanetary travel, because it hasn't yet been done. there is a great mass of unproven theories that are generally accepted as true--but those are not facts. it was once generally accepted that the earth was flat. however--i have a new method of propulsion for this ship, by means of the amplification of magnetic currents, and i expect to supplement the rockets with that new equipment." "i think you're crazy," larry said, "but i'll go along with you anyway." "now you show the proper spirit, even if not good sense," ripon said cheerfully. it was after midnight that night before the _sky maid_ was ready to go. the crew were at launching stations, and the ship's old-fashioned diesels were rumbling as they were warmed up. larry was standing under the dome of duralite glass that covered the upper observation platform when colton came up to stand beside him. "well--we'll be off in a few minutes!" the swarthy second officer said. "wonder if we'll ever come back." "lord knows!" colton shrugged, and his dark eyes were somber. "the police of half a dozen countries are looking for me anyway. i've had my fingers crossed the whole time we've been refitting this craft." "why tell me all this?" larry asked. colton shrugged again, and his smile was half a sneer. "your own reputation isn't much better, gibson. i figure that if this trip works out it may give us both a chance to square ourselves, and if it doesn't we're not much worse off than we are now." "you may have something there," larry admitted. then ripon shouted a command, and the helicopters started to spin. only a handful of loafers watched the _sky maid_ take off. a few waved. others tapped their heads derisively. man's third attempt to navigate the 239,000 empty miles to the moon had begun! * * * * * the old ship's rickety helicopters and creaking diesels could hardly lift her high enough to reach the level required by law before the rockets could be started. high clouds veiled the stars, but the many lights of new york were still visible below them when ripon at last cut in the rocket motors. the _sky maid_ shivered all along her length as their blasting roar began, and then she started to shoot upward at a steep angle. her whole fabric creaked and groaned, and larry gibson shook his head dubiously. a few air-leaks would be all they would need to make their situation utterly hopeless. the drive of the rockets carried them into the belt of clouds. for a few seconds the glass ports were veiled by gray mist. then they were above the clouds and zooming upward in the cold light of the moon. the crew were released from their launching stations as the ship settled down to a smooth routine, and larry took over the watch. a minute later he was alone in the darkened control room with the dim glow of the varied instrument panels to keep him company. already the air was starting to thin out, so he closed the ports and turned on the vessel's air-conditioning system. the atmosphere took on the faintly chemical odor characteristic of travel in a sealed ship in the high places. from somewhere nearby larry could hear a deep voice lifted in song, a voice that rose above the pulsating throb of the rockets. the words were familiar: "there's only a few of us left, and we never were worth a damn, but i'll follow my vagrant star...." larry wondered if ripon was hitting the bottle again. they were in a bad spot if he was, for certainly no one else on board understood the new equipment that ripon had installed to solve the difficulties that had blocked previous attempts at interplanetary travel. in larry's mind there was a steadily strengthening conviction that this whole expedition was destined to failure from the start. it was too makeshift. too poorly organized and planned, too lightly financed. ill-manned and poorly equipped, led by a drunken genius on a rickety ship that wasn't really fit to navigate at all, they were probably sailing to their doom somewhere in the cold reaches of outer space. if they reached the moon at all, it would likely be as a twisted wreck dropped on the cold slope of one of that body's barren craters. larry shrugged. he had made his decision, and he did not regret it. and then, leaning beside one of the control room's glass ports while he kept an eye on the slowly climbing needle of the speed indicator, larry suddenly realized that he had found the peace of mind he had so long been seeking. the clouds were a silvery ocean far below, the moon was a glowing disc ahead. the _sky maid_ snored onward through the night with her rockets pounding. he was again back where he belonged, standing a watch in a vessel's control room. nothing else seemed to matter very much at the moment. ripon came out into the control room a little later, a faded uniform cap pushed to the back of his graying head and his empty pipe clenched in his teeth. "it's tough not to smoke," he rumbled glumly, "but i don't want to put a strain on our none too good air-conditioning equipment. how are things going?" "not so well," larry said, "the rockets aren't balanced, and we have a drift to starboard. three micro-units in every fifteen minutes. i have to keep cutting down the port rocket tubes for short periods to equalize it." "how's the speed?" "not what it should be." larry looked dubiously at the indicator needle. "even with as much rocket power as she's got, we've only built our speed up to a thousand miles an hour even though the atmosphere is greatly thinned. i don't think that we can build up the necessary velocity, chief. i'm afraid it just can't be done." "okay, friend pinzon," ripon said. catching larry's look of puzzled surprise, the gaunt scientist smiled faintly. "there was once a man named columbus who thought he could sail the atlantic, which had not been done before. he was a bit of a faker and a bluff, that genoese adventurer, and there was more than a touch of the charlatan in him. the pinzon brothers who commanded the other two ships of his fleet knew from the start that the voyage could never succeed. i'll admit that columbus didn't find just what he expected to find, but he did cross the atlantic!" ripon laughed, and dropped a hand on larry's shoulder. "hold her on to the course a while, my friend. we're not licked quite so soon!" v ripon was still staring out the control room window at the disc of the moon ahead of them. his voice came somberly as he spoke without turning around. "what's the speed now?" "eleven hundred. velocity of escape is twenty-five hundred." "y'know, larry, it seems one of fate's little ironies that the only hope of saving the people of earth from the gray death lies with this creaking ship and her polyglot crew! oh--i have no illusions about the forlornness of our hope! we have no right to get through. but i'm not entirely a fool, and i have a few aces in my sleeves. i guess it's time to try out my magnetron controls. stand by to cut rocket motors!" ripon moved to several strange-looking control boxes that had been set up at one side of the room. instrument dials glowed into light as he threw a switch, and there came a faint hum. "these tubes are the magnetron oscillators," ripon said. "these switches control the magnetic converters. this other bank governs the selectors." "but i don't get the general principle," larry said. "it's simply a selective utilization of the lines of magnetic force that fill outer space. this ship is naturally para-magnetic, so that she is easily permeable by the lines of force. by charging the wires outside the hull i can make all or part of the ship diamagnetic. furthermore, i can change its charge so that the lines will draw in either direction." "i know enough of the general principles of magnetism to understand that," larry said. "you can vary the direction of the effect, and perhaps vary the dynes. but...." "this indicator shows the hysteresis loop, the lag of magnetic indication behind the magnetizing force at any particular time," ripon continued. "the heart of my system is the group of selectors and amplifiers set up in the compartments directly below us. with them i can select the magnetic currents suited to our course, and amplify them till they move the ship along with them just as the lines of magnetic force move iron filings about a bar magnet. at least," he said with a sudden flash of his reckless smile, "that's what i think i can do. if not, we'll probably never be heard of again. you'd better hope i'm right, young feller!" ripon's craggy profile with its jutting beard was silhouetted against the moon as he bent over his dials and switches. twice he checked them, then he lifted one hand. "ready--cut rockets!" he snapped. larry threw over the lever of the engine room indicator, and the roar of the rockets abruptly ceased. the sudden silence was strangely startling to ears that had become accustomed to that steady pounding astern. running feet sounded in the passage as colton came charging into the control room to find what had gone wrong. for a moment larry had a sensation of falling, and then the _sky maid_ danced about like a leaf in a wind. he steadied himself by clinging to a stanchion and anxiously watched ripon. the gaunt scientist was hunched above his control boards like a gnome, his hands leaping from switch to dial and back again at furious speed. then the motion abruptly ceased. the _sky maid_ became steady as a rock, with the bright disc of the moon dead ahead through the forward port. there was a faint singing sound from one of the control boxes, but otherwise everything was so quiet and still that it seemed as though the ship lay motionless in space. then larry looked at the speed indicator, and saw the needle moving steadily upward. the _sky maid_ was shooting through the heavens at a speed faster than she had ever traveled when she was new and in good condition! * * * * * "gentlemen," said ripon, solemnly shaking hands with both larry and colton, "this is an historic moment! this is a prelude to that day when interplanetary travel becomes as commonplace as are rocket ship flights through the strathosphere nowadays! no longer will the name of crispin gillingwater ripon be a thing of scorn and derision. and just wait till i get a chance to spit in the faces of some of those living fossils back at the national university...." "if the ship holds together!" larry said. ripon sighed. "you _would_ bring that up, young feller. but maybe our luck will hold good. at least this method of travel is less hard on an old craft than the steady strain of a rocket blast. if the ship holds together, we'll be on the moon in forty-eight hours!" colton was grinning broadly as ripon left the control room a minute later. the second officer gave the points of his mustache an added twist, and then rubbed his hands together. "looks like the old goat really came through with something after all," he said. larry looked at him grimly. for all ripon's eccentricities, he was an able man in a great many things. it annoyed larry to hear somebody like colton, a confessed thief and an indifferent officer, speak of him in quite that tone of disrespect. "don't speak of doc ripon in that way when you're with me, colton!" he snapped. the other man's thin mouth twisted in a sneer. "trying to go high hat on me, gibson? you're no better than i am." "if we go into that i'm likely to throw you through the bulkhead," larry said evenly. "so we'll just let it go that i have some gratitude and respect for the man who picked me up out of the gutter--even if you haven't. now clear out of here till it's time for you to take over the watch." for two days and nights the _sky maid_ moved steadily forward on her way. there was, of course, neither day nor night in the airless emptiness of outer space, but they kept routine hours on board. the whole atmosphere of the ship had brightened and changed since ripon's utilization of magnetic force had proven practical. even the slovenly crew went around with their shoulders straighter. the feeling of gloom and failure had been succeeded by one of optimism. now the talk was of whether or not they would really get the desired radium salts on the moon, and of what reward they would all receive when they got back to earth. the watch off duty started a poker game based on notes against the rewards they all expected to get. ahead of the _sky maid_, the moon was now a vast disc that filled half the sky when seen from the control room ports. the bigger peaks and craters were visible to the naked eye now. back in the after observation room, the dwindling but still vast profile of earth had taken on a strange and unfamiliar appearance. it was a lonely feeling, to be so far from that friendly planet. larry wondered how things were now going there, and what had caused the spread of the gray death in the first place. probably a virus brought in on a meteor from some unknown and unhealthy planet. the hope of mankind resting within her rusty hull, the _sky maid_ slogged onward. by earthly standards she was moving at a terrific speed, but compared with the velocity of heavenly bodies and the vastness of interplanetary space she crawled slowly across a small corner of the solar system. vi at last there came the hour when the ship hovered a few hundred miles above the surface of the moon. below them was a vast and uneven surface of barren and pitted rock, round craters and jagged peaks stretching to the horizon in all directions. larry realized now how uneven the surface of the satellite really was, how different from the orange-peel appearance it had when seen through a telescope from earth. all the crew were at landing stations. ripon had adjusted his controls to hold the ship steady in space, and now he stepped back. "there's no use bothering with helicopters," he said. "since there's no atmosphere here, they'd be useless. that's probably what wrecked the ships before us--you can't make an easy landing with rockets alone, and we have no padded landing platform." "can't you lower her down easy with your magnetic control?" larry asked. "that's what i hope to do, but we're not experienced and there may be a jolt. cut off the reserve air tanks, and have all hands put on space suits." the crew of the _sky maid_ looked like a group of fantastic monsters in the metal-cloth space suits with their round helmets of duro-glass. designed for use by emergency repair crews aboard stratholiners in case of trouble, the space suits would keep a man alive and warm in an airless atmosphere for a great many hours. small containers of chemicals kept the air purified, and earphones made communication possible. "stand by for a landing!" ripon's voice buzzed in the ear phones as larry reported all hands ready. "we're going down!" the _sky maid_ went down in a series of jerky drops. with eventual refinement, a ship equipped with the ripon magnetic control would probably be able to come down as gently as a falling leaf, but this first apparatus was crude and experimental. just at the end one of ripon's elbows touched the wrong switch. the rocky surface swept up to meet them at high speed. he shouted hoarsely and spun compensating dials, but before he could check the momentum they struck with a heavy crash. the ship heeled over, and all the lights went out. as larry was flung off his feet he heard a sharp hiss of escaping air. * * * * * momentarily half stunned, larry lay on the floor in a corner of the control room with the body of another of the crew across his legs. then he saw a bulky, space-suited figure heave to its feet across the room and heard ripon's voice in his ear phones. "leaping ray-blasts, what a crash! but i seem to be alive and in one piece. how about the rest of you?" other men struggled to their feet and answered their names. one had his helmet smashed and was already dead in the airless atmosphere that remained after the air had rushed out through the shattered wall of the control room, but the rest had nothing more serious than a few bruises. "well," colton said. "here we are! and here we're likely to stay." "it may not be that serious. the first thing is to take stock of our damage." the _sky maid_, they found on making a complete survey, was far less seriously damaged than might have been the case. the wall of the control room was punctured by a jagged splinter of rock, but there were only a few other minor leaks. many of the compartments had retained their air. once the hole was patched and the other leaks stopped, their reserve tanks still held enough air to let them make a homeward voyage in safety. the network of wires outside the hull would require considerable reconditioning, but none of the internal magnetic equipment was ruined. "about five days' work!" ripon summed up. "and it's primarily a job for the engine room force. gibson, colton, the two quartermasters and i will go ashore with several days' supply of chemical capsules for the air conditioners on our helmets. chief engineer masterson remains in command of the ship. get her back in navigating shape as soon as you can, chief." masterson, a grimy and bullet-headed little man with a drooping mustache and something of the look of a mournful airedale, slapped the side of his duro-glass helmet in a casual salute. larry knew that the ship was being left in good hands. he had come to have considerable respect for the taciturn engineer. he did not know why masterson was on board the _sky maid_, very likely because he had been in some trouble similar to larry's own, but he was certainly an efficient engineer. he wished he felt as sure of the three men who were going ashore with ripon and himself. colton he considered thoroughly untrustworthy, and the two quartermasters were a pair of sullen derelicts of the sort that ripon had picked up off the beach for most of the crew. "landing party ashore!" ripon snapped. "let's get going! this isn't an ordinary exploring party, and every hour counts." vii they stood on a bare expanse of pitted rock. the _sky maid_ had crashed on the outer slope of one of the craters, and the ground rose steadily to the jagged rim of the rocky bowl. other bare peaks were all about them, black teeth against the starry sky. the earth gleamed large and pale above them. the scene was bleak and silent, unutterably desolate and forlorn, and the little group of earthlings drew closer together. then ripon pointed up the ridge. "we'll go up there and look around. larry--you carry the radium detector. we mustn't let the exploring fever make us forget our main purpose in having come here." they toiled slowly up the slope. walking was difficult. due to the power of their earthly muscles on this planet of so much lighter gravity, they had a tendency to bound into the air at each step in spite of the heavy leaden soles on the feet of the space suits. gradually they learned the necessary muscular control, a sort of sliding step, and then they made better progress. ripon was some yards in the lead as they reached the rim of the crater. for a moment the tall scientist was silhouetted against the stars, then he abruptly dropped flat on the rock and motioned back to them to do the same. his voice was a faint whisper in the ear phones. "crawl up here slowly, one at a time. careful!" larry was the first to join him, lying flat on the rock at ripon's side. together they peered down into the crater. it's flat floor was swarming with some sort of queer animal! this particular crater was a small one, and the level floor was only some thirty yards below the rim. larry stared in amazement at the creatures who were coming to sit in long rows around a small mound in the center of the crater. he hardly knew whether to call them men or animals. they had the hard shell and articulated legs of an insect, but their faces had a semi-human appearance in spite of the pair of long antennae that grew out of their foreheads. their feet made a dry rustling sound as they clambered down over the rock, and they carried metal clubs with spiked heads. larry saw that they walked with four of their six limbs while the upper pair were equipped with three curved fingers each. on the top of each antenna was a round ball that glowed with a phosphorescent light. "i thought there wasn't any life on the moon!" larry whispered. ripon grinned at him through the duro-glass of his helmet. "you thought a lot of things that were wrong, young feller!" it was a weird scene in the cold pale light of the earth. some of the insect men came out of small, dome-shaped mounds that might have been houses. others came climbing down the far side of the crater. their glowing antennae bobbed in ceaseless motion, and there was a constant dry clicking. suddenly larry realized that the creatures were talking together! that meant that there was at least some atmosphere on the moon! enough to carry sound! perhaps it had a different composition than the atmosphere of the earth. it was certainly very thin, for the air in the control room had instantly escaped through the shattered side and the man with the broken helmet had smothered, but there was enough here to sustain these odd creatures. then ripon touched him on the arm, and larry saw something that a group of the insect-men were very ceremoniously carrying to the mound in the center of the crater. it was an ordinary metal chair of a very common and familiar earthly pattern, the sort of chair to be found in the cabins and mess rooms of any stratholiner. "one of those old ships must have reached the moon after all!" larry whispered. "that chair must be from the wreckage." "heaven help the survivors if those many-legged devils got hold of them!" "they can't be very strong, with the moon's gravity so slight," larry said. "that doesn't prove a thing. they can be light in frame and still very strong. think how many times his own weight our ant can carry, or how far a flea can jump." the chair had been placed in the center of the mound, and the insect-men drew back. now thin jets of steam or mist began to pour up around the mound, forming a foggy curtain that hid it. the mist only rose a little way, then dropped slowly down again to form an icy film on the cold rocks. the jets ceased, and mist vanished, and larry gibson stared in open-mouthed amazement. a dark-haired girl was standing erect on the crest of the mound! viii the girl was white-skinned and lovely, utterly different from the grotesque creatures who surrounded her. larry was crouching near enough to see her faintly smiling eyes, and the curve of her red lips, and the dark hair that fell to her waist behind. except for the grotesque metallic helmet on her head, and the fact that she wore no clothing except for a silver loin cloth, she might have been a girl of the sort to be seen along the elevated cross-walks of new york city. "do you see her too?" ripon whispered. "i do." "we can't both be that crazy, so she must really be there. but how she breathes in that atmosphere, and how she avoids freezing to death, is more than i can tell you." the ceremony had evidently some sort of a religious significance, for the insect-men were clicking rhythmically and were bowing down before the dark-haired girl. goddess of the moon! the girl's head-dress was a grotesque representation of an insect, set with jewels. at the tops of the flexible antennae were a pair of giant rubies. "boy! wouldn't i like to get my hands on those stones!" colton whispered from where he crouched on ripon's left. then larry noticed something else! a group of perhaps a hundred of the insect-men were moving swiftly forward between the ranks of their bowing comrades. this group carried shields as well as clubs, and they had the purposeful air of men with a grim and serious errand to perform. the girl was staring over the heads of the crowd with a distant and goddess-like manner, and did not notice the newcomers till they had almost reached her. then her eyes widened in alarm. she leaped up from her throne and burst into a torrent of shrill clicking. in an instant the crater was in a turmoil. the group of the heavily armed insect-men charged straight for the mound in the center. others flung themselves in their path, rallying to the defense of the goddess. there was a wild flurry of swinging clubs. the spiked heads clanged on metal shields, or cracked sharply on the brittle brown shells of the insect-men. the significance of the scene before him was still obscure to larry, but it was evident that some kind of a revolt had broken out. the rebels among the insect-men were outnumbered, but their metal shields gave them a big advantage and they were better organized. like a spear-point they drove straight through the confused mass of worshipers and surrounded the low knoll in the center. they brushed its defenders aside and swarmed up toward the dark-haired goddess. larry had already drawn his ray-gun, but ripon was the first to leap to his feet. "come on, young feller!" he roared. "that girl is the first human thing we've seen on the moon. we can't let her down. let's show those many-legged devils how an earth man can fight!" larry and ripon went down the slope of the crater in a series of bounding leaps. the milling insect-men opened before them, seeming to welcome these unexpected reinforcements. some of the rebels had already forced the struggling girl to her knees and were lashing her hands behind her back. a solid rank of them faced about with their round shields locked and a tossing fringe of spiked clubs waving atop the metal wall. * * * * * the two earthlings dove for the shield-wall with their guns flashing. larry ducked as one of the insect-men hurled a club which just missed his glass helmet, then pressed the trigger of his ray-gun. the murky beam of the rays stabbed into the shield, melted a hole through it in a fraction of a second, and struck down the man behind. the flashing ray-guns of the two adventurers ripped the shield-wall asunder. a wave of the loyal insect-men poured in behind them. larry shifted his ray-gun to his left hand, and snatched up a fallen club with his right. it was heavier than he had expected, a well balanced and efficient weapon. the hard brown shells of the rebels cracked like china under the smashing blows of his earthly muscles. then he bounded up on the mound and struck down the pair of rebels who held the girl. her wrists were now tied behind her. throwing an arm about the girl's shoulders, larry hastily faced about. ripon was a few yards away. a ring of his slain lay around him, but his weapons had been knocked from his hands and he was struggling in the grip of a pair of the insect-men. a third of the creatures was swinging a club to strike a blow at the scientist's glass helmet. larry instantly fired, the beam of the ray striking the arm that held the club and shearing it clean off at the shoulder. a viscous yellow liquid dripped out, and the creature dropped writhing on the rock while it clicked in pain. then colton and the two quartermasters came charging belatedly up, and the fight was over. the crater was dotted with the still forms of dead insect-men. larry noticed that their hard shells gleamed dully in the dim light. the surviving rebels had fled off across the far rim of the crater, and the rest of the throng had gone chasing after them. no one remained in the crater except the strange girl and the party from the _sky maid_. when larry had freed the girl's hands, she turned to the five earth-men and touched her forehead in a gesture of thanks. then she stepped across to touch some hidden spring on the far side of the mound, and a trap door opened in what had apparently been solid rock. the girl led the way down a narrow flight of stairs, motioning for the last man down to pull the trap closed behind them. they stood in a small chamber that had walls of roughly smoothed rock. it was evidently the work of men, for tool marks showed here and there. it was lighted by a green globe set in one wall. the globe appeared to be made of some kind of flexible glass, and it glowed with a faint greenish radiance that overcame the darkness enough to give the place a dim and eerie light. at one side of the room was an oval hole like a slanting well cut in the floor. beside it stood a pile of low, flat carts. they were about two feet wide by four feet long, and they were supported on axles bearing small wheels the diameter of a man's hand. the girl spoke to larry twice, first in the clicking talk of the insect-men and then in some soft and musical tongue that was unlike anything larry had ever heard. both times he shook his head. motioning for them to follow her, she put one of the low carts down near the rim of the hole and sat on it. then she gave a push with her hands--and vanished. "come on," larry said, raking another of the carts. colton stared at him. "down that hole?" he asked. "why not? we've got to find out what all this is about." * * * * * a second later larry gibson found himself shooting down into the interior of the moon by means of a sloping tunnel cut in the rock. a series of the greenish globes were set in the ceiling at intervals to give the rocky shaft a dim light. the wheels of the cart ran in two grooves cut in the floor, and he shot swiftly downward with a dull humming sound. larry was trying to estimate the speed of his downward movement. it was not so terribly fast, probably not really as fast as the nearness of the walls made it appear while they flashed by on either hand. the slope was a gentle one. although he had gathered considerable momentum, he had no feeling of the car being out of control. as the minutes passed, larry saw something else. the moisture that had been on the outside of his space suit from the air within the _sky maid_ had frozen into a white frost a few seconds after the breaking of the control room wall let the outer cold into the ship. now the frost was melting! they were getting into warmer regions as they went down. perhaps they were also running into a heavier atmosphere! larry held his hand up before him, and had a distinct feeling of pressure against it from the rush of air sweeping up to meet him. a minute later he had tested the atmosphere with the portable oxygen-gauge carried in the equipment pocket of any space suit. then he took off his helmet. the air was quite warm, and though still very thin it was definitely breathable. its clean, earthy odor was a pleasant contrast to the chemical product used over and over again inside the helmet of a space suit. a moment later he saw a brighter light ahead and realized that he had come to the bottom of the long shaft. they were in a square room whose walls were of polished gray stone. as larry got up from his cart and moved in aside from the landing platform, the girl gave him a friendly smile. she had already taken off her ornately jeweled head-dress and placed it in a metal cabinet fastened to the wall. completely without embarrassment, she tied a strip of gayly colored silk across her bare breasts. then she tossed her long hair back from her forehead and bound another strip of silk to keep it in place. "that was quite a ride," larry said. he had spoken in english, knowing that the girl would not understand but hoping the sound of the words would convey a generally friendly impression. she stared at him in startled surprise for a second. "it is much pleasanter than the upward trip," she said at last. "but--but you spoke in english!" larry gasped. "why shouldn't i? my father is a man from earth. i am diana staunton." ix as the others came sliding down into the room, larry gave each one a formal introduction to diana. the glow in the girl's eyes showed that she enjoyed their utter amazement. for a girl who had been born on the moon, even though of earthly parents, diana staunton had a great deal of poise and self-possession. "i am only a goddess to the sluggish minds of the insect-men," she explained in answer to ripon's question. "to our own people of the lost caverns i am simply the daughter of one of the nobles." "i knew your father thirty years ago," ripon said. "he has always told me that other men from earth would come some day." "your father can tell me most of the things i want to know, but i am wondering how you managed to survive up there on the surface where there is little or no air and it is always so cold." "i could not stay very long." from a fold in her loin cloth the girl drew out a tightly closed glass bottle that held some white tablets. "these contain oxygen mixed with some gases unknown on earth, the whole very strongly compressed into solid form. ten minutes after i swallow one, it is safe for me to go out on the surface. the effect lasts for about fifteen minutes." "pretty risky if anything delays you," larry said. diana shrugged, and her blue eyes grew somber. "someone has to do it. the loyalty of the insect-men is our greatest protection against the evil lords of gral-thala. this is the first time there has ever been anything like a revolt among the insect-men. i do not know what lies behind it, but it probably means trouble for us of the lost caverns." colton was the last to come down the rocky shaft. larry noticed that the second officer was ill at ease, disinclined to meet his eyes, and wondered if colton was ashamed of either his late entry into the fight or his fear of coming down into the moon's interior. hardly likely! from what he knew of gerald colton, the man was not likely to be ashamed of anything he did. they went through a maze of gray walled passages, still trending downward. once or twice larry thought he heard stealthy footsteps behind them, but there was no one in sight when he looked back. on several occasions they passed sentries wearing a makeshift armor, who saluted diana with long bladed swords. sometimes they spoke to her in english with a peculiar soft accent, sometimes in that strange tongue that diana had first used. larry noticed that these lunarians looked only slightly different from the peoples of earth. they had larger eyes, and a greater delicacy of feature. the principle distinguishing feature was their very thin legs. often they had wide shoulders and deep chests, but since they did not need strong supporting muscles in view of the moon's slight gravity their legs were thin and narrow. the sentries stared curiously at the earth-men in their bulky space suits, but the fact that the newcomers were with diana staunton seemed to be sufficient passport. they began to pass a greater number of people in the corridors, and finally they stepped through a heavily guarded gate and came to a vast cavern. the place was huge, extending for a good mile ahead of them and with a lofty roof lost in the shadows overhead. some of the gigantic columns that supported the roof were made of heavy stone blocks. others were natural rock that had been smoothed and polished. all over the floor of the cavern were narrow streets, and small cottages built of some queer composition that came in a rainbow of different colors, and little patches of some sort of green grass. a golden and rather misty light pervaded the whole cavern. square shafts of a brighter radiance darted down from above at irregular intervals, and wherever one of them struck the floor of the cavern there was a small patch of cultivated ground with long-leafed plants. "agriculture by chemical control!" ripon whispered in larry's ear. diana glanced back at them over her shoulder. "this is chotan, largest of the lost caverns," she said. "the council of elders is now in session, and it will be best that we go direct to them." "why do you call these the lost caverns?" larry asked. "because we who live here are outlaws, and the location of these vast caves is not known to the lords of gral-thala who rule the other side of the moon." "apparently not all the inhabitants of the moon are so friendly," ripon said. "if you came into the hands of the lords of gral-thala," she said grimly, "they would tear the skin from your bodies and use it to lace their scented golden boots!" large-eyed lunarians stared curiously at the earth-men as they hurried through the streets of the underground village. diana led them direct to a broad-beamed, red-roofed building that stood by itself in the center of the cavern. a dozen elderly men sat behind a long table of carved wood that was black and cracked with age. it was, larry realized, the first wooden thing he had seen since he landed on the moon. at either side of the chamber stood a squad of armored warriors. larry was staring at a curious device that was carved in the center of the table, and carried on a banner hung above the heads of the council, and inlaid in a white metal on the bluish steel shields of the guards. and then he recognized it! it was the crescent earth, the profile of the mother planet as seen from the moon when the americas were still in sunlight and the shadows of night were creeping across the atlantic. the sight of it made him home-sick. the crescent moon had been a religious symbol to many of the ancient races of earth, and it was fitting that the crescent earth should hold a similar place on this isolated satellite. it seemed to larry that diana was a trifle nervous over something. she had entered the council chamber with an air of confidence, lifting one arm in a stately gesture of greeting and asking the elders to accept the men from earth as friends and guests, but he sensed a degree of uncertainty behind her manner. in hasty phrases she told the council of the revolt of part of the insect-men, and of the timely arrival of the strangers from the mother planet. "and so i request that you accept these men into the brotherhood of the caverns!" she finished. the graybeards behind the long table nodded gravely, but before they could speak another voice rang but in a sharp challenge. "and i, o elders of chotan, demand that these interlopers be put to death in accordance with the ancient law of the caverns concerning unwanted strangers!" x the speaker was a fair-haired young man in a green cloak. he looked more like an earthling than a lunarian, with his sturdy legs and small eyes. he pointed an accusing finger straight at larry in a dramatic gesture, and diana wheeled to face him with anger in her voice. "you talk very loudly of the ancient laws, xylon, for a newcomer only recently taken into the brotherhood because you fled as an outlaw from the lords of gral-thala!" "i did not make the laws!" xylon retorted. "the death penalty for strangers has not been strictly enforced for many years--or _you_ would not now be alive! it is up to the decision of the elders!" the council chamber was in an uproar, with shouted phrases flung back and forth. larry laid a hand on the butt of his ray-gun. a keen-eyed officer of the guards caught the gesture, and instantly larry found a pair of rifles directed at his chest. at least, they looked like some sort of compressed air rifles. they had fiber stocks, and long barrels, and a cylindrical magazine beneath the barrel. then a deep voice dominated the tumult as a red-haired man in full armor forced his way through to the forefront of the crowd. "the girl is right, o elders and members of the brotherhood!" he boomed. "xylon talks like a fool. i, pyatt of kagan, urge that the strangers from earth be accepted. let xylon remain among us for a little while longer before he attempts to dominate our councils!" larry could sense the swing of sentiment in their favor, could feel the lessening of the tension. the man called xylon shrugged and turned away. then the council took a formal vote, waving the ancient death penalty and allowing the strangers the freedom of the caverns. one of the elders near the end of the table rose to his feet. he wore the typical black robes of the council, but as larry looked closely at the man's lined face he saw the resemblance to diana and knew that he was looking at lester staunton. "since these men are from what was once my own land," staunton said, "i will make them comfortable in my house for the duration of their stay here." as the crowd began to stream out of the council-chamber, the red-headed man pushed his way through to ripon and larry. he was unusually burly and big-thewed for a lunarian, and though his face was marred by a pair of old scars he had a wide and cheerful smile. "welcome to the cavern of chotan!" he boomed. "i am pyatt of kagan, military commander of all the armed forces of the caverns. later i will want to talk to you about that revolt of the insect-men, which is something that has not happened before. also, we will drink a goblet of wine together." "then you have wines on the moon?" ripon asked, visibly brightening. "aye, wines of many sorts. though my own taste runs more to the strong-waters that fire the blood and set a man's head to spinning." "i can see that you and i have a lot in common!" ripon grinned. * * * * * just before they left, xylon came up to shake hands with larry. "no hard feelings, earthling!" he said. "it is just that the safety and liberties of the caverns are very precious to one like myself, who has so recently become an outlaw, and i did not think that we should take any chances." "that's all right," larry said shortly. now that he saw xylon at really close range, he realized that the man was older than he had thought. his appearance of youth vanished when you saw the many fine wrinkles in his face and the weariness around his eyes. he had a dissolute appearance. xylon might be sincere in his bid for friendship, but larry felt that there was something serpentine and evil about the man. with diana and her father and a few others, they walked along one of the many winding paths of chotan. larry noticed that the chemically grown plants had no scent at all. the motionless, warm air was suffused with a misty and golden light. small, neat houses built in various bright colors stood amid their plots of grass. it was a strange scene to earthly eyes, that cavern far below the moon's chill surface, but it was a pleasant spot in its way. the women they passed along the walks were dressed like diana, in a gayly colored loin-cloth with a narrow band across the breasts. most of the men wore a loose, colored cloak in addition to the single garment. only a few were armed. larry had taken off the right mitten of his space suit to shake hands with pyatt and xylon in the council chamber. several times he had started to replace the mitten, but something had always distracted him and he was still carrying it in his left hand. now, as he happened to give the mitten a shake, a small insect of a blood-red color fell out and landed on the walk. it looked something like a miniature scorpion. larry had only a hasty glimpse before pyatt of kagan leaped forward and crushed the crawling thing with the heavy sole of his sandal. "that was a _spanto_!" he said. "their bite means death within ten seconds. i wonder how it came to be in your glove!" "i wonder myself!" larry said grimly, looking across the field at the green-cloaked figure of xylon, who had turned off on another of the branching walks. it would not have been hard for xylon to have dropped the insect in his glove! as if in answer to his thought, diana spoke quietly: "i do not trust xylon any farther than i can see him, friend larry! there is something unclean in his eyes when he looks at me." "if he looks at you too much while i'm here i'll break his jaw!" larry said. the girl looked up at him with a sudden smile that was also a challenge. "i begin to understand why my father has always said that i would like the men from earth better than the lunarians!" xi they sat in professor staunton's laboratory, a square chamber where earthly equipment taken from the wreck of his space-ship was mingled with typically lunarian furniture and equipment. the walls were light blue, of that polished composition resembling bakelite that was used for building in the caverns. the walls were about ten feet high, and they ended in an ornamental cornice without any ceiling or roof at all. overhead there was a glow of misty light, and far above the rocky top of the cavern. "why should we need roofs?" diana said in reply to larry's surprised comment. "here in these caverns there is neither rain nor snow nor wind, nor any change in temperature at all. the walls give privacy, and there is no need for anything else." ripon was bending over a table on which staunton had spread a large map of the moon. the cavern of chotan was indicated by a red dot, and larry saw that there were a dozen others scattered around within a radius of a few hundred miles. "our space-cruiser was wrecked near one of the entrances to this cavern when we landed here thirty years ago," staunton said. "as you have guessed, it was the inability to land safely with rockets, in a practically airless atmosphere where helicopters were useless, that smashed us. as you did, we had fortunately put on space suits before trying to land. our ship was too badly wrecked for any chance of return." "but how have you succeeded in getting all these people to learn english?" ripon asked. "they knew that language before i came! but it is best that i give you a hasty outline of lunarian history. the simple-minded but husky insect-men were the aboriginal inhabitants of the moon. long ã¦ons ago, while most of the people of earth were living crudely in caves and using chipped stones for tools and weapons, an isolated people developed a high civilization in what i have roughly identified as the region of the himalayas. a series of great earthquakes destroyed their civilization, but a large number of them escaped and came to the moon in some kind of a space-ship. here they found, in those days, a small planetary body that had a thin but breathable air. they founded a civilization on the other side of the moon where it is always sunny, and called it gral-thala. those were pleasant days, if the old legends are to be believed, the golden age of lunarian civilization." for a moment staunton paused. all those in the room, including the lunarians who had been familiar with this tale since childhood, hung intently on his words. the broad face of pyatt of kagan was somber and moody as he sat bent forward with the scabbard of his sword resting across his armored knees. "as the centuries passed, the atmosphere continued to thin," staunton went on, "so the ancients took care to preserve what was left. gral-thala is in the fertile part of the moon, and lies in a vast valley completely surrounded by a lofty mountain range. by means of the superior engineering knowledge of the ancients, they built a lofty wall or barrier along the crest of the range so that its top is miles above the level of the valley floor. they then sucked all the air within the great barrier. gral-thala itself thus lies in a great pool of air surrounded by the ranges and the barrier. on the rest of the moon, as here, air only remains in deep crevices and caverns like this." "but these caves were a great labor in themselves..." ripon began. * * * * * "originally these caverns were built as outposts of gral-thala, built here because of their nearness to valuable mineral deposits. people came out from the sunlit cities within the great barrier to put in a tour of duty in the caverns. again life on the moon had reached a pleasant equilibrium. and then came the great disaster! some two centuries ago a group of several hundred outlaws fleeing from earth came here in a big space-ship." "the _mercury_!" larry exclaimed. "exactly. those men and women who came from earth were few in comparison to the population of the moon, but they were cruel and ruthless and they had weapons of war. the peaceful lunarians had at that time no weapons at all, for they had no need for them. within a few months the invaders made themselves lords of all gral-thala! that was when english, the language of the invaders, came to be spoken by everybody on the moon as well as the softer tongue of the lunarians themselves. a few of the hardier folk in gral-thala fled to these caverns as outlaws. the invaders made only half-hearted attempts to come after them, and with the passing of the years the location of these refuges has been forgotten by people living within the great barrier. that is why these places are now known as the lost caverns." "and the invaders still rule?" "their descendants are still lords of gral-thala. cruel and ruthless they always were, decadent and dissolute they have now become as well, but they still rule the sunny valley that was the pride of the ancient lunarians. they hold the power, and they are aided by a few groups among the people of gral-thala who have sacrificed their honor to fawn upon their masters. our spies, who penetrate beyond the barrier, tell us that before long there will come a day when the people are ready for revolt--but the time is not yet." "but surely!" said pyatt of kagan, his deep voice breaking in on the low monotone in which staunton had spoken, "surely our visitors will return to earth, now that interplanetary travel has become possible, and bring us the warriors and equipment to storm the high palaces of the tyrants of gral-thala!" "i should think that the confederation of earth would send help, particularly since the original invaders were outlaws from that planet," staunton said. "how about it, friend ripon? how are conditions back on earth at this time?" ripon straightened up and shook his shoulders. the glow in his eyes faded away, and the lines in his face deepened once more. "the lunarians can look for no help from earth until one thing is accomplished," he said. "i have been letting scientific enthusiasm make me lose sight of our reason for coming here. how are conditions on earth, you ask? i can tell you in a single sentence. unless we of earth very quickly get a new supply of radium salts suitable for use with the riesling method, in a few weeks we all perish!" "i do not understand." in a few hasty phrases ripon sketched the development of the terrible plague that was so swiftly robbing earth of its inhabitants. at the end staunton leaned back in his chair. "such salts are available on the moon in ample quantity," he said slowly, and something in the quality of his voice robbed the words of the reassurance they would otherwise have held, "but--they are all located well within the area of the great barrier. and the lords of gral-thala would never let you have even a single milligram!" "then there's only one thing to be done!" larry stood up and began to peel off his space suit. "if someone will show me the way, i'll go into gral-thala and bring out as much of the radiatron extract as i can carry." "and i will go with you!" boomed pyatt of kagan. "by gorton and laila, mythical gods of the moon, it will take more than a few of those cold-eyed tyrants to stop us!" xii time was the thing that counted. the remorseless pressure of minutes and hours that passed and could never be recalled! the tyrants who lorded it over gral-thala had no weapons more deadly than the electronic guns that had been common on earth two hundred years before. a battalion of troops from earth, wearing armor of dura-steel and carrying ray-guns, could probably have overthrown the invaders very quickly. but--there was no time! the toll of the gray death was increasing with each passing hour, back there on the good green planet, and the little group on the moon would have to do what they could without hope of assistance. they could not pause for proper preparations or careful planning. it was only half an earth day after they had landed on the moon, time enough to snatch a few hours' sleep, that larry found himself moving up toward the surface in a slowly crawling cable car. chotan already lay behind and far below them, and the oxygen indicator fastened to the sleeve of the space suit showed him that the air was thinning rapidly. colton and pyatt were with him. all three of them wore space suits of the lunarian patterns, that had a metal helmet with glass windows at the front and sides, for the difference in design of the space suits from the _sky maid_ would have made them too conspicuous. pyatt had come along because he had often penetrated beyond the great barrier in disguise, and a second lunarian was waiting for them up on the surface. ripon had also wanted to come, the idea of this daring raid setting the old, reckless light danging in his eyes. finally he agreed that one of the leaders of the _sky maid_ expedition had better remain in the caverns in case of disaster to the raiders. "that's the hell of getting along in years, young feller!" he rumbled regretfully. "there's nothing i'd like better than to penetrate the barrier with you and pull the whiskers off the tyrants in their lair. a quick wit and a ready weapon! but i couldn't keep up with you younger men if the going gets hot--though i never thought the day would come when i'd hear crispin gillingwater ripon admit a thing like that!--and you'd better go on without me." "we'll be back soon," larry said. ripon snorted. "if you're not back in five days i'm coming after you with the crew of the _sky maid_ and as many of the folk of the caverns as i can get to come along!" * * * * * the cavern of chotan was in that part of the moon which is sometimes in sunlight and sometimes in darkness, and it was night when they came out of the tunnel. the moisture on the space suit instantly froze into a fine white frost. a few lunarian sentries waited for them there, and nearly a hundred of the insect-men. with them were two carts that had high wheels and springs, something like an old-fashioned earthly buckboard. for a few moments, pyatt talked to the leaders of the insect-men in their clicking tongue. the glowing knobs atop their antennae bobbed up and down as they nodded their heads in understanding. then pyatt motioned colton into one of the carts and climbed in beside him. another lunarian, slender even in the bulky space suit, climbed into the second cart beside larry. pyatt swung his right arm forward. a score of the insect-men instantly scampered ahead as scouts, spreading out like the spokes of a fan. small parties went out to either flank. the rest, about thirty to each cart, gripped the trailing ropes and darted ahead with the wagons following behind them. they went at almost incredible speed, the four legs of each giving them a steady drive. even though the insect-men were picking the smooth stretches of the rock and were evidently following a definite though unmarked trail, it was rough going. the light wagons jolted and banged as they whizzed along, and larry had to cling to the rail with both hands to keep from being thrown off. "is all the way as rough as this?" he panted to his companion. "better soon," the lunarian said shortly. after about three hours they turned into a smooth and level road. it wound up and down over the rolling rocky plain, evidently a highway of great age. occasionally they passed crumbling ruins beside it. larry supposed that the road and the ruins dated back to those very ancient days before the lunarians withdrew their shrinking supply of air within the great barrier. now that the road was smooth, the insect-men pulled the carts along at a whizzing pace. the light wheels whirred as the wagons shot ahead. the scene, larry reflected, was like a nightmare. all about him were the chill mountains and craters of the moon, lifting their jagged peaks against the cold stars. ahead of the speeding wagon ran the toiling cluster of insect-men, their hard shells gleaming faintly in the starlight and their glowing antennae bobbing in a swift rhythm as they ran. the treads of the wheels rattled on the rocky surface of the road, the horny feet of the insect-men made a steady scraping sound as they ran. the two men seated in the cart ahead were monstrous and misshapen figures in their space suits. larry's companion had remained sullenly silent, in spite of several efforts to start a conversation. this was unusual in one of the normally pleasant and talkative lunarians, but larry had not thought much about it. now, as he made some remark about the speed of their progress, he heard a low chuckle and in his earphones sounded the voice of diana staunton. "yes, larry, we travel fast. in a few days we will enter the zone of sunlight." "_you_," he exclaimed. "this expedition is too dangerous. i would never have let you come if i had known." "why else do you think i kept so silent until now, when it is too late to send me back?" she asked, and though he could not see her face through the glass of her helmet in the darkness he could tell that she was smiling. "neither would pyatt of kagan or my father have let me come. i stole the space suit of the young man who was to accompany you and left him locked in a storeroom." "you will have to remain outside when we go within the barrier." "where you go, i go," she said with finality. * * * * * sunrise on the moon! there was no sudden onslaught of light as on the earth, for the moon day was twenty-eight days long! yet, as they progressed steadily toward the horizon, the moon's rotation brought the edge of the sun gradually into sight above the barren horizon, and as the days passed, a blinding glare of light swept in upon them and they moved the dark glasses into place in front of the windows of their space-suit helmets. the temperature rose rapidly with the coming of the two weeks' sunlight, and before long the frost on the space suits was melting. then, stretching along the crest of a mighty mountain range ahead, larry saw a lofty gray wall that went so high its top was almost lost from view above. they had come within sight of the great barrier! xiii several times along the way they had been halted by sentry-patrols from some of the other outlaw caverns, who warned them that an unusual number of strong parties of troops from gral-thala were roaming the waste-land. however, they came without incident to a tiny outlaw hide-out. this was within half a mile of one of the caverns that was under the domination of the lords of gral-thala. two hours later larry and the others stood with a score of other people, in an air-lock in a great tunnel that led through the mountain range and into gral-thala. all these people were residents of the valley returning from a tour of duty in the caverns, and the four outlaws from chotan had been furnished with forged documents that gave them the same identity. the space suits had been removed and hung on numbered racks. the three men wore the tight tunics and loose trousers that were the customary dress within the valley, as distinguished from the loin cloth and cloak of the cavern outlaws. this was fortunate, for the trousers concealed the sturdy earthly legs of larry and colton which would have stood out in sharp contrast to the typical spindly shanks of the otherwise well-built lunarians. diana wore a loose robe, with tight wrappings concealing her hair and a thin veil over her face. a heavy guard of soldiers checked the papers of all the travelers before they let them through. these troops wore light armor, and each carried an electronic gun slung from his shoulder. the officers were evidently of the invaders, cruel-eyed men cast in the same mold as xylon. the men were lunarians, generally of a rather debased type and drawn from among the worst element in the population. a heavy-featured trooper glanced at larry's papers in a perfunctory manner, then handed them back. "all right, all right!" he growled. "get along. don't block the way!" the tunnel ended on the inner slope of the mountain range surrounding gral-thala, where many cars ran down the steep incline into the city below. it was a pleasant and smiling land that larry gibson saw before him, a sunlit and fertile valley so vast that even the lofty range on the far side was invisible over the horizon. towns and villages dotted the plain. farms lay among their fertile fields. a small river wound through the center. directly below him, clustered against this part of the valley wall, was a mighty city. "this is the city of pandonaria," diana's voice came softly through her veil, "capital city of gral-thala." the city itself was a terraced mass of colored buildings cut by many streets and interspersed with gardens. several towering palaces of white and gold, the abodes of the lords of gral-thala, dominated the lower buildings. it was good to see real sunlight again! to see birds flying overhead! to smell the odor of flowers and growing things, in contrast to the flat and motionless air of the lost caverns! it was hard to believe that this pleasant spot was really the scene of such a brutal tyranny as he had been told. then they rounded a bend in the sloping road and came to an abrupt halt. * * * * * at the side of the road stood a sort of gallows, made of strips of a ruddy metal bolted together. from it hung the nude body of a young lunarian girl. she was suspended by her bound wrists high above her head, and her feet swung far off the ground. from the clotted blood at her bound wrists, and the way the eternal sun of the valley had burned her skin, larry knew that she had hung there many hours. the girl was far gone but she was not yet dead. at intervals her drooping head moved feebly from side to side. a pair of armored soldiers leaned on their weapons below the gallows. around the girl's neck hung a sign, lettered in the archaic english script that was the official language of gral-thala: "this girl dared strike one of the nobles of gral-thala who condescended to notice her." fierce anger filled larry gibson's heart, a consuming anger that set his clenched fists shaking. for some reason he thought of diana. though she stood only a few feet away from him, he visioned her hanging from such a gallows if the dissolute tyrants of this land ever stormed the lost caverns. then pyatt of kagan laid a hand on his arm. "careful, my friend!" the lunarian hissed. "your anger shows on your face, and that is bad. we cannot help that poor girl now. come!" they went down into the city, avoiding the broad boulevards and keeping to the narrower streets where the poorer people were. as they passed by the base of one of the high palaces, they came to the body of a girl who lay crushed on the stones and had evidently been thrown or jumped from one of the upper windows. an aged man stood astride the body, leaning back and shaking his skinny fists at the white and gold bulk of the palace above him. "woe be upon the lords of gral-thala!" he screamed in his shrill old voice. "triple woe upon the tyrants and upon the decadent parasites who fawn upon them. evil lies in wait for ye, lurking in your white palaces with your guards and your harlots! the hour of doom is not far away! the vengeance of gorton and laila may be long delayed, but it comes in the end! woe to the lords of gral-thala!" an uneasy, sullen, murmuring crowd was gathered around the ragged old man although they left a broad circle of vacant space around him and the body of his granddaughter. a few troopers of the garrison were making a half-hearted effort to push the crowd back. they were uncomfortable in the face of the unspoken but obvious hatred of the throng. larry and the others prudently kept to the back of the crowd. even so, they were near enough to see what happened next. silver bells rang sharply, and lackeys called an arrogant summons to clear the way. in the midst of a circle of armed guards, porters carried a swaying gilt litter. on the cushions of the litter rested a man. it was one of the nobles of gral-thala, a perfumed degenerate in silken robes with a rouged and painted face. for a moment he stared at the crowds with his arrogantly scornful eyes. then, as he saw the old man beside the girl's body and heard the curses he was shouting, his patrician face was distorted into a sneering frown. the noble snarled an order, and one of his guards lifted his electronic rifle. there was a flash of blinding light! a sudden clap of miniature thunder, and a smell of ozone. the man-made lightning bolt struck the old man in the chest and knocked him sprawling across the body of his granddaughter. with a faint smile the noble leaned back on the cushions of the litter and waved languidly to his porters to move on again. "let us go, my friends!" pyatt whispered hoarsely. "we cannot right all the wrongs of gral-thala at one stroke, and our mission is the most important thing at the moment." xiv they were walking slowly down one of the quiet streets of the city, a quarter where there were few guards and little chance of discovery. larry noticed that all the windows were equipped with heavy shutters, so that the light could be closed out when the inhabitants of this land desired to sleep. it was a place of unending daylight, always turned toward the sun, where darkness never came. colton was more interested in the metal rails that ran along the walks on the outside of the buildings. "my lord!" he said softly, "these are gold!" "of course," pyatt of kagan said absently, "gold is one of the most common metals in gral-thala. our problem is the matter of the radium salts. i happen to know that they are stored in small boxes made of ura-lead, in one of the government storehouses. it would be easier to steal some direct from the mines, but there is no time for that because of the question of proper packing and handling. we must risk everything on a bold attempt to raid the warehouses." "suits me," larry said quietly. just then diana gripped him by the arm and jerked him back against the wall of the nearest building. "look there!" she hissed. another litter was passing along the cross street just ahead of them. this litter went in evident haste, with lackeys swinging whips to clear the path and the passenger bending forward to urge his bearers to greater haste. the man who rode in the litter was xylon! the four outlaws stared at each other in grim and ominous surprise. there had been no doubt of the identity of the man who had just passed within a few yards of them. "but what does _that_ mean?" larry gasped. "it means that i have been a fool!" pyatt snarled. "xylon is evidently no outlaw who came to the caverns to seek shelter, but a spy sent out by the lords of gral-thala. now i understand the reason for that revolt among the insect-men! he must have stirred it up in an attempt to kidnap diana here because of her hold over those simple creatures. now the location of the lost caverns is at last known to the tyrants, and there will be an attack in force." "and xylon knows that we are here in pandonaria!" diana exclaimed. "which means that all our lives hang by a thread no heavier than a woman's hair! we must get under cover at once! then we will send word back to the caverns by secret radio, that they may prepare for an assault. after that we will plan an attempt on the radium salts." the outlaws of the lost caverns had certain confederates within the city, and they now took refuge in the house of a small merchant who was a distant cousin of pyatt. larry watched as pyatt and the merchant crouched over the sending set concealed in a small closet built in the thickness of one of the walls, the arkon-bulbs flashing as they sent the warning to chotan to be spread to the other caverns. at last pyatt straightened up. "at least that is done," he said. "now we will wait two hours, which will be the time of the third meal. there will be few people on the streets, and the warehouse guards will be drowsy, and we will have our best chance." * * * * * pyatt and colton had gone somewhere else in the house, and larry sat with diana in a small room whose windows looked out on the green fields beyond the city. the girl had loosened her blue veil so that it hung in soft folds about her chin. "this is the first time in my life i have been anywhere but in the caverns and on the waste-land," she said moodily. "this valley of gral-thala is a pleasant place." "you would like earth even better." "i suppose i would. will you take me back to that earth of yours when you return, larry?" "not until the gray death is overcome! i would not want to take any chance of it striking you down." "do you love me, larry?" she asked, without either coquetry or embarrassment. "i guess i do. of course, we've only known each other for a few hours--but i guess i do." "i am glad," she said simply. the two hours passed, and pyatt came striding back into the room. they had given him one of the ray-guns brought ashore from the _sky maid_, and he carried it thrust in his girdle close to his hand. "it is time to go," he said. "we must make our attempt now, win or lose. where is colton?" "i thought he was with you." "haven't seen him in two hours!" a hasty search of the merchant's house and small grounds revealed no trace of the missing officer. pyatt stood glowering blackly and pulling at his chin. "i don't like it," he said. "yet, if the soldiers had taken him, they would have come for us as well." a different thought was running through larry's mind, a grim and unpleasant suspicion. he was remembering colton's past history ... his general sullenness ... the greed that he had shown throughout the entire expedition. he was also remembering that he had seen colton in deep conversation with xylon a few hours before they had left chotan. "i am afraid," he said bitterly, "that colton has sold us out to xylon and the lords of gral-thala for promise of reward. we had better get out of this house right away, before...." larry never finished that sentence. there was a roaring crash, and the door was shattered by the impact of a pair of electronic bolts fired by the soldiers who had crept up to the house. armored figures came pouring in the door! others were at the back. pyatt of kagan, fighting furiously, went down under press of numbers. larry managed to get his ray-gun up and fire one blast that crumpled a charging trooper in mid stride, but then half a dozen gripped him and the brief fight was over. they were taken! xv the hands of the three prisoners were tied behind their backs, and nooses were placed around their necks. then they were dragged out into the street. the merchant was not taken prisoner at all, simply killed out of hand with the body left lying across his shattered threshold. a thin-lipped, hooked-nosed officer spat in larry's face as he was led past the body of the dead merchant. "not for you will there be such an easy ending," he sneered. "an example is to be made. you will die before crowds, in the plaza of the four virgins, and the process will be a slow one." they were surrounded by a double rank of guards as they were led along by the nooses about their necks. all three had been stripped to a loin cloth, and the sun was scorching hot upon larry's back and shoulders. at least, he thought thankfully, diana's long black hair gave her some protection. there were jeers and hoots as they were led through the crowded streets, but most of them came from members of the tyrant class and from the few over-dressed and foppish lunarians who aped their masters. the mass of the people gazed in stony and somehow sympathetic silence. into one of the tall white-and-gold palaces of the lords of gral-thala they were taken, and down into stone-walled dungeons far underground. they were placed in a single cell. they stood with their backs against the walls, arms out-stretched and wrists lashed to rings set in the stone, able to move little more but their heads. then, for a while, they were left alone. "well," said larry with grim humor, "here we are." "so it seems!" pyatt's voice was rasping and bitter. "i am indeed a fool for ever having allowed xylon to live in the cavern of chotan, in spite of the kind-hearted ruling of the elders." "what will they do with us?" larry asked. pyatt hesitated, licking his lips and glancing at diana, but the girl answered for herself. "we shall probably be skinned alive in the public square, dying slowly under the torture," she said. "it is the favorite punishment of the tyrants for those they particularly hate." it was a day of triumph for the lords of gral-thala. xylon's triumphant return with the information that would lead to the wiping out of the always troublesome outlaws of the lost caverns, and the capture of the three prisoners, made it a holiday for the ruling class of the valley. they came in hundreds to see the three captives. the famous military leader of the outlaws ... the girl who was considered a goddess by the primitive insect-men of the waste-land ... the the stranger from that distant earth whence their own ancestors had fled. they came to throng the dungeon corridor and stare in at the trio of captives spread-eagled against the wall of the cell. larry watched them through the barred door. for hours on end there were always a few of them in the corridor, staring and jeering. foppish men in white and gold with their curled hair laden with scent. haughty and jewel-clad women whose sharp featured faces held even more cruelty than their male companions. many were attended by lunarian slave girls whose fettered hands held their trains up from the floor, and the bare backs of the slave girls were usually marked with the crossing red marks of whips. larry knew, now, that the tales told in the caverns about the cruelty of the lords of gral-thala had not been exaggerated. * * * * * xylon came to see them after a while, opening the cell door and walking in to stand sneering at them with his thumbs hooked in his jeweled girdle. "colton sold you out for the promise of wealth and a place in the ranks of our nobles," he said. "it will be a pleasure to watch you die." for a moment he walked over to stand in front of diana who looked back at him with an expressionless face. "you are not a bad-looking wench. i can take you for one of my slaves if you wish to be agreeable." "i would rather go with an insect-man!" the girl said with calm scorn. xylon shrugged and turned away. "so be it. at that, it would be a pity to rob the crowd of the pleasure of watching you die." as near as larry could judge it, the equivalent of an earthly day had passed before they were taken out of the cell. they were given an hour to ease their stiffened muscles. then the guards bound their wrists before them, and by the trailing ends of the ropes led them out of the dungeons and through the streets to a broad open space just at the foot of the inclines that led down from the tunnel by which they had entered the city. the plaza of the four virgins, named from the four gigantic statues of polished stone that had been placed at its corners in some long ago day before the invaders came, was a vast paved space in front of an ancient temple that was now used as a government building. in front of the temple a metal scaffold had been erected with two heavy uprights and a cross-piece. the rulers of gral-thala were sprawled in cushioned ease on the steps of the temple, well guarded by their troops, and the floor of the plaza was filled with the common people of the city. these latter were present in great number, a silent and ominously sullen mass. the three prisoners were stood in a row on the scaffold. their hands were raised above their heads, and the ropes made fast to the cross-piece so that they were held tautly erect and motionless. sharp laughter and occasional jests came from the nobles and their women clustered on the steps, but as larry looked out over the crowd in the plaza he saw faces that were grim and intent. the threat of the electronic rifles of the guards would keep the unarmed mob from trying to aid the prisoners, but there was no doubt where their sympathies lay. glancing up at the tyrants grouped on the temple steps, larry suddenly saw colton. the former second officer of the _sky maid_ now wore the white and gold robes of a noble of gral-thala. xylon kept his promises! colton flushed uncomfortably when his glance met larry's grim stare, quickly turning his eyes away. he looked uncomfortable and ill-at-ease. larry glanced at him again a few minutes later and saw colton staring at diana's bound and motionless form with definite misery in his eyes. one of the nobles stepped to the front and began to address the crowd. shrill yells and catcalls drowned his words. the guards raged, but the men in the front ranks of the mob were discreetly silent and they could not reach or identify the culprits in the ranks behind. many of the nobles were muttering nervously among themselves, showing definite signs of fear. "there was never a scene like this in pandonaria before!" pyatt of kagan exulted from where he was bound beside larry. "we may die, but our death is likely to stir the people to such a pitch that the revolt will soon come!" xylon, for all his faults, was made of sterner stuff than most of his fellow nobles. he sneered down at the muttering crowd, then signed to the officer commanding the guards. "pay no attention to the dogs," he commanded sharply. "give these three a taste of the whip before the flayers rip the skins from their bodies. begin with the girl." a heavy-featured man in a black tunic stepped up to diana, pulling the lash of a heavy whip through his hands to test its suppleness. before he could strike there came a sudden interruption. a small car had been speeding down the incline from the tunnel entrance and now a gilded officer of the invaders leaped out and came running across the plaza. "great news, oh xylon and nobles of gral-thala!" he shouted. "one of our patrols has captured a great force of outlaw warriors and their insect allies, who were moving in to raid our nearer caves. some more earthlings are with them!" "good, by gorton!" exulted xylon. "we will delay the execution of these three till the others are here to see it." larry's last hope was gone. he had remembered ripon's promise to come after them if they had not returned quickly, and in the back of his mind had been the thought that the doughty scientist might yet accomplish a rescue in some way. now that hope had vanished. he sighed, and beside him diana sagged visibly in her bonds. "guess it's the end," she said. "good bye, larry!" xvi from where he stood on the scaffold, larry could see a number of the big transport cars coming down the incline. they were crowded with prisoners and guards, and he caught the gleam of the hard brown shells of insect-men. once unloaded from the cars, they all formed up in columns and came quickly across the plaza. behind the front rank of guards larry saw ripon, and some of the men from the _sky maid_, and many whom he recognized as leaders among the lunarians of the lost caverns. it was all over now. the prisoners trudged along like beaten men, utterly disheartened although they were but thinly guarded. the nobles grouped on the temple steps were laughing loudly, all their nervousness of a moment ago gone before the reassurance of this victory. then, as the prisoners were halted in the plaza directly before the double line of soldiers that guarded the temple, an officer beside xylon leaned forward to point down at the commander of the patrol that was bringing in the prisoners. "that man wears the insignia of an ensign of the first rank," he shouted, "but there is no such man in the ranks of our officers! there is treachery here!" before the man's words had died away, crispin gillingwater ripon had whipped a ray-gun out from under his cloak and smashed the officer's chest into a charred pulp with the deadly blast of the rays. in an instant the plaza was a wild turmoil. the pretended prisoners drew their hidden weapons. those who had been masquerading as guards, using the armor they had taken from the soldiers they surprised and overwhelmed when they stormed the tunnel entrance, threw the uniforms aside and charged into the fight. the rippling crashes of the electronic guns rang out again and again, the murky flashes of the earth-men's death rays stabbed into the fray, and a clicking horde of insect-men charged home with their spiked clubs swinging. [illustration: _in an instant the plaza was in a wild turmoil.... the rippling crashes of the electronic guns rang out again and again. the murky flashes of earth-men's death rays stabbed into the fray, and a clicking horde of insect-men charged home with spiked clubs swinging._] for the first few moments the fighting centered around the scaffold. xylon led a charge of picked men down to seize and keep the three prisoners bound there, ripon came storming through to effect a rescue. when the mã©lee was over, larry and pyatt were free and xylon had retreated back to the temple steps, but diana had disappeared. "we got the rest of the crew from the _sky maid_ and all the men we could collect at chotan and crept up to the tunnel mouth," ripon panted as he thrust a ray-gun into larry's hand. "we took the guards by surprise and killed them before they could warn the valley behind." it had been a daring raid, and at first its sheer audacity had carried it near to complete victory. now the superior numbers of the guards were beginning to tell, and more of the troops of gral-thala came pounding up at the double. the crash of the electronic guns became a steady roar, and bodies were thickly strewn about the blood-smeared surface of the plaza of the four virgins. then, with a long-drawn and sullen shout, the mass of watching lunarians flung themselves on the soldiery. hundreds died, but the others tore the guards to pieces with their naked hands and then snatched up their weapons. the people of gral-thala had risen against their oppressors at last! * * * * * with the uprising of the people, the battle ceased to be a fight and became a massacre. the troops were selling their lives, as dearly as they could, but thousands more citizens carrying improvised weapons were pouring in from every street and the thing was only a matter of time. then, in the rear of the panic stricken mass of nobles who were fleeing into the temple to make a last stand, while the vengeful pack bayed at their heels, larry suddenly saw xylon! the tyrant was standing beside one of the great stone columns that supported the portico of the temple. he held the half naked body of diana before him as a shield. the girl's hands were still tied and she could not pull away. a swarm of insect-men, who were bounding up the temple steps, halted as they saw xylon hold an electronic pistol to the head of their goddess. "keep back or she dies!" he shouted. "she is hostage for our safety!" larry lifted his ray-gun, and then lowered it again with a groan. he dared not shoot with diana's struggling body in the way. nor had he any doubt that xylon would kill the girl without compunction if attacked. xylon began to edge back toward the temple door. larry still stood indecisive, the others seemed frozen in their places. then another white-and-gold figure darted out from the temple behind xylon. the renegade colton twisted the gun from xylon's hand! the thing was over in an instant. xylon released diana and turned on colton with an oath, and the girl instantly dropped to the ground. steel flickered in the sunlight. xylon drove a long knife home between colton's ribs, but before he could dart away larry's ready ray-gun struck him down with its blast. his quivering body rolled slowly down the steps till the insect-men reached it and literally tore it into bloody bits. xvii the dying colton was sinking fast. his face was gray as he looked up with a faint smile at the others who were grouped around him. "i never was much good," he said faintly. "guess it just wasn't in the blood. gold always led me into twisted paths, and i couldn't resist xylon's offer. but it did something to me when i saw the way those devils were going to torture the girl. well--i guess i paid my debt at the end." "you've paid it--and you'll live to go back to earth with us," larry said. colton shook his head, his eyes glazing. "don't try to kid me. i'm cashing in my checks," he said--and died. now that it was all over, larry felt very tired. he put one arm around diana, and leaned back against the base of the column. there was still some intermittent fighting going on where mobs of vengeful lunarians had cornered some of their oppressors, but the victory was won. ripon looked about at the carnage with a satisfied smile and them sheathed his ray-gun. "it was a good fight!" he said. "i haven't had as much fun since the time i wrecked a saloon in port mahon. now, young feller, you just take care of the lady here while i take a squad and get the radium salts from the store-house." "and the _sky maid_?" larry asked. "that sour-puss masterson has been standing over the men with a ray-gun in one hand and my last jug of rum in the other ever since you left. all the repairs are finished. we start back to earth as soon as we can get our cargo aboard." "then the people of your planet will be saved?" diana asked. "they will be saved. and as soon as the gray death is checked i'll come back for you. then the moon will have to get along without its goddess for a while." "i'll be waiting," she said. an investigation into the nature of black phthisis; or ulceration induced by carbonaceous accumulation in the lungs of coal miners, and other operatives. by archibald

stated to be caused by the inhalation of substances floating in the atmosphere of the coal-pit, such as the products of the combustion of gunpowder, the smoke from the miner's lamp, and the other foreign matters with which the air of the mines is heavily charged, in consequence of their defective ventilation. in the mines in which gunpowder is used, the disease is most severe in its character, and most rapid in destroying the pulmonary tissue. the carbon in some cases is expectorated in considerable quantity for some time previous to death; in others, it is retained, and accumulates to a great extent in the lungs. as the disease advances, the action of the heart becomes feeble; and the appearance of the blood indicates a carbonaceous admixture. the carbonaceous deposit seems to supersede or supplant the formation of other morbid bodies in the substance of the lungs--such as tubercle; for in individuals belonging to families in which there exists an undoubted phthisical diathesis, tubercle is never found on dissection. the views expressed in this communication called forth the following remarks. professor christison called attention to the new and important fact, of the carbonaceous matter being found in the circulating mass. he attached great importance to dr makellar's researches. professor allen thomson remarked, that the presence of this carbonaceous matter in the blood, by no means proved, that it was formed in, or from the blood. dr hughes bennett said, that the antagonism of this carbonaceous disease to tubercle, was a fact of great interest and importance, especially in connection with two other recent observations; viz. 1st, that the depositions of carbon in the lungs of old people, (which french pathologists describe,) are not found associated with tubercle; and, 2d, that under the supposed cicatrices of pulmonary tubercular cavities, a layer of carbonaceous matter is commonly found. dr makellar's paper called forth some interesting observations from the president, professor simpson, and others. black phthisis, or ulceration induced by carbonaceous accumulation in the lungs of coal-miners among the many diseases incident to the coal-miner, none come oftener under medical treatment, than affections of the respiratory and circulating organs. while the collier is subject--during his short but laborious life--to the other diseases which afflict the labouring classes in this country, such as inflammations, fevers, acute rheumatism, and the various eruptive diseases, he, at last, unavoidably, falls a victim to lesions within the cavity of the chest, arising from the nature of his employment. in the present communication, it is proposed to lay before the profession a series of remarks, which i have been enabled to put together, with a view to elucidate the cause and progress of that very peculiar pulmonary disease, incident to coal-miners, which i shall denominate black phthisis, or ulceration induced by carbonaceous accumulation in the lungs. the rise and progress of the malady may be thus sketched: a robust young man, engaged as a miner, after being for a short time so occupied, becomes affected with cough, inky expectoration, rapidly decreasing pulse, and general exhaustion. in the course of a few years, he sinks under the disease; and, on examination of the chest after death, the lungs are found excavated, and several of the cavities filled with a solid or fluid carbonaceous matter. during the last ten years, my attention has been much directed, in the course of my professional labours in the neighbourhood of the coal-mining district of haddingtonshire, to the above phenomena in the pathology of the lungs, which have not hitherto been brought so fully before the profession, as their importance demands. the subject presents a very interesting field of investigation to the physiologist and pathologist. when we consider the difficulties which the medical man has to encounter, in prosecuting his researches in morbid anatomy in a mining district, it is sufficiently explained why the peculiarly diseased structures in the body of the coal-miner should have been left so long uninvestigated. not many years ago, the obstacles in the way of _post mortem_ examinations among colliers were insurmountable, and consequently, till lately, few medical men could obtain permission to examine, after death, the morbid appearances within the chest of a collier. with the rapid advance in the general improvement which has been going on, the collier's position in society has become greatly elevated; and his deeply-rooted superstitious feelings have been, to a great extent, dissipated. let us hope that the school-master will find his way into every collier's dwelling, enlightening his too long uncultivated mind; and that the foolish prejudices shall cease, which have been hitherto the barriers to _post-mortem_ examinations in his community. the only medical writers, as far as i am aware, who have brought this subject before the notice of the profession, are, dr j. c. gregory, in the report of a case of peculiar black infiltration of the whole lungs, resembling "melanosis," (_edinburgh medical and surgical journal_, no. cix., october 1831); dr carsewell, in an article on "spurious melanosis," (_cyclopædia of practical medicine_, vol. iii); dr marshall, in a paper in _the lancet_ for 1836, entitled "cases of spurious melanosis of the lungs;" dr william thomson, now professor of medicine in the university of glasgow, in two able essays (_medico-chirurgical transactions of london_, vols. xx. and xxi.), wherein he gives a number of very interesting cases, collected from various coal districts of scotland, illustrating different forms of the disease; dr pearson, in the _philosophical trans._ for 1813, on the "inhalation of carbon into the pulmonary air cells;" and in a paper, by dr graham, in vol. xlii. of the _edinburgh medical and surgical journal_. recently, professional and other writers have directed attention to the influence of various occupations in the production of diseases of the chest. the pernicious employment of the needle-pointers, razor and knife-grinders of sheffield, and other manufacturing towns in england,[1] have not only engaged the attention of the public at large, but science has been at work to ascertain, with as much accuracy as possible, the relative effects of the different avocations, on the constitutions of those occupied in these destructive employments. researches of this nature tend much to the well-being of society, as they make us acquainted with the maladies and sufferings peculiar to certain classes of our fellow-men; and point out, also, the causes of their early decay, and premature death. the coal-miners--those in whose behalf i would now solicit the intervention of science--are most valuable in their place, and their exhausting labours promote, in no small degree, our domestic comforts. some of the diseases of colliers have in past time been very much overlooked by the medical inquirer. there has been, within the last few years, a very searching investigation as to the employment of women and children in coal-mines; and by the laudable exertions of lord ashley--a nobleman whose name shall ever be honoured among miners, and by all who have the true interests of that community at heart--an act of the legislature has been passed, declaring it unlawful for any owner of any mine or colliery whatever, to allow any female to work therein; and also enacting, that no boy under the age of ten years can be employed in mines. it is to be regretted, however, that his lordship did not embody in his measure, provisions enforcing the free ventilation of mines under government inspection; for nothing would tend more to improve the health of those employed in them. in the course of the inquiry, which formed the prelude and basis of lord ashley's act, much valuable information regarding the diseases of colliers was elicited; and no one can peruse the voluminous parliamentary report pertaining to these investigations, without being struck with the very general prevalence of affections of the chest among miners. it is to be hoped, that the interesting facts in regard to disease, which this recent most necessary investigation has laid open, will be the means of directing the attention of scientific men to the subject, with a view to obviate, as far as human efforts can, the evils which have been exposed. it may at first appear difficult, to point out the means of removing effectually the causes of the pulmonary carbonaceous disease of miners, but, be the difficulties what they may, humanity encourages us to make the attempt. in the _first place_, let us endeavour to ascertain the cause, and _secondly_, to suggest means for the mitigation or prevention of this scourge. my present remarks do not refer to coal-miners in general, but to a district in scotland, in the lothians, east of the river forth, where the labour is hard, and where its severity is in many cases increased by a want of proper attention to the economy of mining operations. these operations, as at present carried on, are extremely unwholesome, and productive of diseases which have a manifest tendency to shorten life. i draw the materials of my description from what i saw in a part of that district referred to, where the various cases, hereafter to be adduced, came under my medical treatment, and where i had the privilege of examining the morbid appearances after death. the locality[2] in which my observations were made, is that part of the lothians, extending from south to north, stretching from the foot of the lammermoors towards the sea-coast, including the coal-works of preston-hall, huntlaw, pencaitland, tranent, and blindwells. in this range of the coal-formation, the seam of coal is variable, but generally exceedingly thin, varying in thickness from eighteen inches, to three or four feet. it is with difficulty that mining operations can be prosecuted, from the extremely limited space in which the men have to move, and from the deficient ventilation. it appears, after thorough investigation, that in the majority of the coal mines above mentioned, ventilation is very much neglected, and that this neglect is partly caused, by the immunity of these mines from carburetted hydrogen gas, which exempts them from the danger of explosion. but though there be no explosive gas, there is generated, to a certain extent, in the more remote recesses of the pit, carbonic acid and other gases, producing the most injurious effects--impairing the constitution by slow degrees, and along with the more direct cause (the smoke from the lamp, candle, and the product of the combustion of gunpowder,) making progressive inroads on the health of the unfortunate miner. and how, i ask, can it be otherwise, in such circumstances? so long as it is possible for him to go on--so long as there is air enough to support the combustion of the lamp or candle, the labourer must proceed with his toil. i say, from there being no fire-damp, less attention is paid to ventilation, and it is a common occurrence with colliers in these localities, to be obliged to leave their work, from there not being a sufficiency of oxygen to keep their lights burning, and support respiration; and this temporary cessation of labour under such circumstances is regarded as a hardship by some proprietors, while the bodily sufferings of the miner, shut up and necessitated to labour in this situation, are little considered. after labouring beyond a given time in those confined situations, there is a much freer action of the respiratory apparatus, the oxygen is considerably exhausted, and to make up for this deficiency, the volume of air inspired, (impure though it be,) is much greater. every now and then, there is a disposition to draw a deep breath, followed by a peculiar and gradual decrease of strength. therefore, in these forcible expansions of the chest, it is to be expected that a considerable quantity of the floating carbon will be conveyed to the cellular tissue. the atmosphere of the coal mine at length becomes so vitiated, by the removal of the oxygen in breathing, and the substitution of carbonic acid, that the respiration becomes gradually more difficult, and the exhausted labourer has ultimately to retire from the pit, as there is no other mode by which the noxious air can be removed--owing to the underground apartments being so small--than by gradually allowing purer air to accumulate. the miner is thus enabled to return to his employment. it is about thirty years since miners in this district adopted the use of coarse linseed oil, instead of whale oil, to burn in their lamps; and it is very generally known, that the smoke from the former is immensely greater than that from the latter, and many old miners date the greater prevalence of black spit to the introduction of the _linseed_ oil. this change took place entirely on the score of economy. any one can conceive how hurtful to the delicate tissues of the respiratory organs, must be an atmosphere thickened by such a sooty exhalation. it is now known, that this disease originates in two principal causes, viz., _first_, the inhalation of lamp smoke with the carbonic acid gas[3] generated in the pit, and that expired from the lungs; _second_, carbon, and the carburetted gases which float in the heated air after the ever-recurring explosions of gunpowder, which the occurrence of trap dykes renders necessary. to those acquainted with mining operations, an explanation of the coal and stone hewing process is unnecessary; but, for the sake of the uninitiated, i may be allowed to state, in explanation, that, previous to any coal hewing, it is needful to remove various strata of stone, to open up road-ways, and break down obstructing dykes, by the aid of gunpowder. all coal-miners are engaged exclusively with one or other kind of labour; that is either in removing stone or coal: and the peculiar disease to which each class is liable, varies considerably, according to the employment. for instance, the disease is more severe and more rapid in those who work in the stone, than in those engaged in what is strictly coal-mining, while, at the same time, both ultimately perish in consequence of it. the fact of the disease being more acute in stone-miners, i am disposed to attribute to the carbon and other products of the combustion of gunpowder, being more irritating and more destructive to the lungs. a very striking instance of this occurred, a few years ago, at the colliery of the messrs cadell of tranent. a very extensive coal level was carried through their coal field, where a great number of young, vigorous men were employed at stone-mining, or blasting, as it is called, every one of whom died before reaching the age of thirty-five years. they used gunpowder in considerable quantity:--and all expectorated carbon. it was long a very general belief with medical writers, that the various forms of discoloration in the pulmonary tissue was induced by some peculiar change taking place in the economy or function of secretion, independently of any direct influence from without. they were, therefore, usually supposed to belong to the class of melanotic formations, from presenting, as their distinguishing feature, a greater or less degree of blackness. but, by recent investigations, it has been proved, that the infiltrated carbon found in the bodies of coal miners is not the result of any original disease, or change taking place within the system,[4] but is carbon, which has been conveyed into the minute pulmonary ramifications, in various forms, during respiration; and which, while lodged in these tissues, produces irritation, terminating in chronic ulcerative action of the parenchymatous substance. the very minute bronchial ramifications first become impacted with carbon, and consequently impervious to air; by gradual accumulation, this impacted mass assumes a rather consistent form, mechanically compressing and obliterating the air-cells, irritating the surrounding substance, and promoting the progressive extension of the morbid action, till the whole lobe is infiltrated with carbonaceous matter, which, sooner or later, ends in ulceration and general disorganisation of the part. it is evident, in tracing the disease through its various stages, up to that of disorganisation, that wherever there is an impacted mass in any part of the pulmonary structure, this is followed, sooner or later, by softening, from its irritating effects upon the tissues by which it is surrounded; and as this softening process advances, the innumerable sets of vessels[5] composing the dense network of capillaries are broken down, extending the cyst, so that, as the cysts enlarge, they gradually approximate to each other, till all at last become merged in one great cavity. the majority of colliers, soon after they engage in their mining operations, become afflicted with bronchial disease to a greater or less extent. those who are hereditarily predisposed to pulmonary irritation, are, it is my decided belief, more liable to "black phthisis" than others; but i cannot suppose it possible, that any constitution, however robust and sound, could resist the morbid effects resulting from carbon deposited in the lungs. tubercular phthisis is not at all prevalent in any collier community with which i am acquainted, only occasional cases occurring, and that amongst females. it is my impression, that a phthisical person, engaged in the operations of a coal-pit, similar to those in haddingtonshire, would come under the influence of the carbonaceous disease, instead of the true phthisis; for, in all the _post-mortem_ examinations which i have conducted, connected with this pulmonary affection, i have never found tubercular deposit:--while other members of the same family, having a like predisposition, and who never entered a coal-pit, have died of phthisis. can carbon inhaled destroy a tubercular formation? i never knew or heard of a case of black spit in a female collier, and this is accounted for by the circumstance, that the women, when permitted to labour, previous to the late prohibitory enactment, were only occupied as carriers; and from their movements towards the pit shaft, in transporting the coals, were enabled to inhale at intervals a purer atmosphere. the boys also, who were employed as carriers to the pit shaft, continued to labour with like impunity, from their occasional change of situation; but the miner, lying on his side in a confined, smoky recess, under ground, gasping for breath, proceeding with his exhausting labour, cannot fail, in his deep inspirations, to draw in the deleterious vapour, to the most minute ramifications of the pulmonary structure, and, as he daily repeats his employment, so does he daily add to the accumulation of that foreign matter which shall ultimately disorganize the respiratory apparatus. in the first stage of the affection, there is an incessant dry cough, particularly at night, and all the prominent symptoms of bronchitis are present. indeed, from the time a man becomes a coal-digger, and inhales this noxious air,[6] there is ever after a manifest irritation in the lining membrane of the respiratory passages, which is apparent before carbon in any quantity can be supposed to be lodged in the lungs. the mucous membrane of the air passages, by its continually pouring out a viscid fluid, has the power of removing any foreign matter that may be lodged in them. now, should this membrane, owing to previous irritation, lose to a certain degree this secretory power, then the foreign body adheres to it, and is retained, and this, i think, constitutes the preparatory stage of black deposit. in tracing the progress of the disease, it is my belief, that immediately after the carbon is established in the air-cells, the absorbents become actively engaged, and the glandular structure soon partakes of the foreign substance. one of the peculiar features, as we shall find, when we come to describe cases, is, that the secretory function is ever after so changed in its character, that the gland which formerly secreted mucus, to lubricate the passages, now performs the same service with muco-carbon, and continues to do so during the remainder of the patient's life--even, as i have often seen, long after he has desisted from the occupation of a coal-miner. in fact, it constitutes a striking peculiarity of this disease, that when the carbon is once conveyed into the cellular tissue of the lung, that organ commences the formation of carbon, thus increasing the amount originally deposited, as was strikingly exemplified in the case of duncan and others, to be afterwards detailed. duncan had not for fifteen years been engaged in mining operations, nor was there any possibility of his having inhaled more carbon: yet in him it was found to have increased to the greatest possible extent, leaving but a small portion of useful lung. i have been long impressed with the belief, that the carbon is contained in considerable quantity in the blood, particularly in the blood of those far advanced in the disease. this impression arises, not only from its dark and inky appearance, but from its sluggish flow, and non-stimulating effects on the heart and general system; and when we examine the morbid condition of the pulmonary structure,--ascertain the presence of carbon in the glandular system and minute lymphatic vessels of the lungs, and consider the relation existing between them and the circulating fluid, we cannot suppose it possible, that such a mass of foreign matter should be lodged in their parenchymatous substance without imparting a portion to the blood. i was never more struck with this, than in the case of duncan, where the blood was more like thick brownish ink than vital fluid. no one who has witnessed the economy of these pits, can doubt the inhalation, to a great degree, of lamp and gunpowder smoke into the pulmonary tissue. what may be its chemical action there, is a question for us to attend to as we proceed. if it be considered an established fact, that carbon is inhaled, possessing all the chemical qualities of that substance found floating in the air of the coal-mine, and either expectorated from the lungs during life, or retained in those organs till after death, we cannot but conclude, that the black matter is the result of an external cause, and that that cause is the sooty matter. another question arises here, in connection with this phenomenon, viz.--does the carbon increase in the pulmonary tissues after the collier has relinquished the occupation of a miner, and when there can be no further inhalation, and if so, whence comes this increase? it must be admitted, judging from several of the cases which follow, that it does considerably augment. from this remarkable fact, does it not appear probable, that when carbon is once lodged in the pulmonary structure by inhalation, there is created by it a disposing affinity for the carbon in the blood, by which there is caused an increase in the deposit of carbon, without any more being inhaled. _appearances on dissection._ in classifying the morbid appearances observed in the pulmonary structure, i arrange them according to divisions corresponding to three stages of the disease. _first_, where there exists extensive irritation of the mucous lining of the air passages; and the carbon being inhaled, is absorbed into the interlobular cellular substance, and minute glandular system, thereby impeding the necessary change upon the blood. _secondly_, where the irritative process, the result of this foreign matter in the lungs, has proceeded so far, as to produce a variety of small cysts, containing fluid and semi-fluid carbonaceous matter, following the course of the bronchial ramifications. _thirdly_, where the ulcerative process has advanced to such an extent, as to destroy the cellular texture, and produce extensive excavation of one or more lobes. _stethoscopic signs._--in the early stages, the sounds indicate a swollen state of the air-passages, and vary in character according to the part examined. the whistling and chirping sounds are loud and distinct in the large and small bronchial ramifications, and both from the absence of expectoration and the presence of the pulmonary bruit, the highly irritated state of the mucous linings is apparent. the affection ultimately assumes a chronic form, and continues present in the respirable portions of the organ during life. as the carbonaceous impaction advances, the sounds become exceedingly dull over the whole thoracic region, and in many of the cases no sound whatever can be distinguished. where the lungs are cavernous, it is very easy to discover pectoriloquy, from the contrast to the general dulness, and when pleuritic and pericardial effusion advance much, it is difficult to ascertain the cardiac action. such is a short account of the _cause_, _progress_, and _morbid appearances_ of this deadly malady, as they came under my notice. * * * * * from a variety of cases to which my attention was directed, i i have selected _ten_, with the _post-mortem_ appearances in nine of them. these cases extend over a period of eleven years, all of them exhibiting, with some slight variation, the same character of disease, and proceeding from the same cause--inhalation of carbonaceous matter. some of the cases occurred as far back as the years 1833-34, while the last case came under my notice within these twelve months. of the ten patients, six were engaged at one period with stone-mining, and four were entirely coal-miners; eight expectorated carbonaceous matter, and two did not show any indication of black infiltration from the sputum; six exhibited, on examination, most extensive excavations of the pulmonary structure; and three only general impaction of these tissues, with numerous small cysts containing black fluid; the body of the tenth, i regret to say, was not examined, owing to neglect in communicating in time the death of the patient, which took place a few weeks ago. these morbid appearances exhibit three stages of the disease in regular progression. the first is that where the carbon is confined to the interlobular cellular tissue, and minute air-cells, producing cough, dyspnoea, slight palpitation of the heart, and acceleration of pulse, while, at the same time, the patient continues able to prosecute his daily employment. the respiratory sounds, in this state of the chest, are loud and distinct. such a condition of the pulmonary structure is often found on examination in the carron _iron-moulder_, who has been killed by accident, or has died from some other disease, having been subjected in the course of his employment to the inhalation of carbonaceous particles. the second is that stage where the softening has commenced in the several impacted pulmonary lobular-formed small cysts throughout the substance of one or more lobes, the contents of which may either be expectorated or remain encysted, giving rise to most harassing cough, laborious breathing, and palpitations, dull resonance of chest, and obscure respiratory murmur. the third and last stage, is that in which the several cysts in one or more lobes have approximated each other, forming extensive excavations, the prominent symptoms of the disease becoming considerably aggravated, and the powers of the system sinking to the lowest degree of exhaustion. * * * * * case 1. george davidson, collier from his youth. when i first saw him professionally, in may 1834, he was aged thirty-two. from his earliest years he was employed about the coal-works in pencaitland parish, and when very young, he went down the pit to assist in conveying coals to the shaft, and ultimately became a coal-miner. for a considerable length of time, he enjoyed good health, having neither cough, nor any other affection. he was well-formed, and robust in constitution. a few months previous to my seeing him, he had taken to the employment of stone-mining in the pit at huntlaw, where he was accustomed to labour, and soon after being so engaged, he began to complain of uneasiness in the chest, and troublesome short cough, quick pulse, especially at night and in the morning, for which he sought medical advice, and was treated for bronchial affection. he continued to prosecute the employment of stone-mining in this coal-pit so long as his strength would permit, which was a little more than two years, when (august 1836) he was entirely disabled, from general exhaustion. by this time his cough had much increased, and there was considerable dyspnoea, accompanied with sharp pain in the thoracic region, both in walking quickly, and when lying down. pulse 80. he expectorated bloody tough mucus without any tinge of black matter. all remedial means were adopted with a view to the removal of the irritation of the chest, without producing any very decided effect. the thoracic pain was occasionally subdued, but the cough became incessant; loss of appetite, rapid emaciation, and cold nocturnal sweats, with slow weak pulse, supervened. after a severe fit of coughing, during one of his bad nights, the black expectoration made its appearance, in considerable quantity, by which his sufferings were for a few days alleviated, when the cough returned in the same degree of severity, and was again mitigated by the black sputa, which was expectorated without difficulty, and from this time (october 1836) there was no interruption to a free carbonaceous expectoration. in the early part of this man's illness, the stomach, the alimentary canal, biliary and urinary secretions, continued unimpaired; but as the cough advanced, gastric irritation, which was followed by vomiting during the paroxysms, annoyed him; and for the last eight months of his life, he suffered occasionally from severe attacks of gastrodynia, which, when present, had the effect of considerably modifying the thoracic irritation, and allaying the cough. there was nothing very remarkable in the character of the urine; the quantity voided was small, and very high coloured, with occasionally a lithic deposit. the fæces were natural, and smeared with dark blue mucus. on examining the chest with the stethoscope, the crepitant ronchus was heard in the upper part of each lung. there was general dulness throughout the lower part of both, with the exception of a small space at the inferior angle of the left scapula, where pectoriloquy was distinctly heard, from which was concluded the cavernous state of a portion of that lung. the heart's action was languid, and often intermitting, producing vertigo and occasional syncope. the pulse was gradually becoming slower; and at this time, (nov. 1836,) it was _forty-three_ in the minute. i was informed by this man, that his chest affection first became manifest, after being engaged with a difficult job in a newly formed coal-pit at huntlaw, where he had very little room to conduct his mining operations, which were carried on with the help of gunpowder, and where he experienced a sensation of suffocation from the confined nature of the pit,[7] which did not permit of the exit of the evolved carbon, and ever after, his cough and difficulty of breathing had been increasing rapidly. during the greater part of the period he was under my charge, he continued to expectorate black matter, of the consistency of treacle, mixed with mucus in considerable quantity, and i would suppose, taking the average of each week, that he expectorated from ten to twelve ounces daily of thick treacle-like matter. i had the curiosity, during my attendance on this patient, to separate the mucus from the carbon, by the simple process of diluting the sputa with water, and thereafter separating and drying the precipitated carbon. i was enabled by this means to procure about one and a-half drachms of a beautiful black powder daily, and in the course of a week, i had collected near to two ounces of the substance. this process i continued for some weeks, till such time as i had procured a sufficient stock of this remarkable product of the pulmonary structure, and i am certain that the same quantity, if not more, could have been obtained till his death, in dec. 1836. it is undoubtedly a striking phenomenon, connected with the pathology of the chest, that the human lung can be converted into a manufactory of lamp black! towards the close of this poor man's existence, the countenance and surface of the body assumed a leaden hue, from the very general venous congestion, and as his system became more exhausted, and he was about to sink in death, the gastric irritation and nocturnal cold sweats which had been long present with him considerably increased, along with a cough so severe as actually to produce vomiting of the black sputa. his tongue and fauces became so coated with the expectoration, that a stranger viewing the patient would have said that he was vomiting black paint.[8] this case resembled in many of its features, one of tubercular phthisis, more than is generally found in the disease before us, there being cough and expectoration, dyspnoea, sharp pain in the thoracic region, colliquative sweats,[9] and great emaciation, while at the same time, the pulse was slow and weak, not exceeding thirty-six in the minute for a week before death. no hectic heat of skin, but an extraordinary depression of the arterial action, arising evidently from the redundancy of carbon deposited in the pulmonary tissue, preventing the proper oxygenation of the blood circulating in the organs, and thereby producing a morbid effect on the whole system, which sufficiently explains the cachectic condition of the body. _post-mortem examination, twenty-four hours after death._--in removing the anterior part of the thorax, the lungs appeared full and dilated, and of a very dark colour. both lungs were strongly attached to the pleura costalis, and a very considerable effusion of straw-coloured fluid was found in both cavities of the chest. a few irregularly situated dark glandular bodies were observed on the surface of the costal pleura at each side of the sternum, and on the mediastinum. the lungs were removed with difficulty on account of the strongly adhesive bands attaching them to the ribs, and in handling them they conveyed the impression of partial solidity:--several projecting, irregular firm bodies, were felt immediately beneath the surface of the pleura, and there was also present emphysematous inflation of the margins of the upper lobes. in transecting the upper lobe of the left lung, it was found considerably hollowed out, (to the degree of holding a large orange,) and containing a small quantity of semi-fluid carbon, resembling thick blacking, with the superior divisions of the left bronchus opening abruptly into it. many large blood-vessels crossed from one side of the cavity to the other, to which shreds of parenchymatous substance were attached. the inferior lobe was fully saturated with the thick black fluid, and it felt solid under the knife, and several small cysts containing the carbon in a more fluid state were dispersed throughout its substance, in which minute bronchial branches terminated, and by which this fluid was conveyed to the upper lobe, and thence to the trachea. in examining the right lung, the upper, and part of the middle lobe were pervious to air, and carried on, though defectively, the function of respiration, while the interlobular cellular tissue contained the infiltrated carbon. the inferior portion of the middle and almost the whole of the under lobe were densely impacted, so that on a small portion being detached, it sank in water. both lungs represented, in fact, a mass of moist soot, and how almost any blood could be brought under the influence of the oxygen, and the vital principle be so long maintained in a state of such disorganization, is a question of difficult solution. in tracing the various divisions of the bronchi, particularly in the inferior lobes, some of the considerable branches were found completely plugged up with solid carbon; and in prosecuting the investigation still farther, with the aid of a powerful magnifier, the smaller twigs, with the more minute structure of cells, were ascertained to contain the same substance, forming the most perfect _racemes_, some of them extending to the surface of the lung, and to be felt through the pleura. the lining membrane of the permeable bronchial ramifications, when washed and freed from the black matter, exposed an irritated and softened mucous surface, which was easily torn from the cartilaginous laminæ. the interior of the trachea and its divisions gave evidence of chronic inflammatory action of long standing which extended from about midway between the thyroid cartilage and bifurcation to the root of the lungs. a considerable number of lymphatic glands, filled with--to all appearance--the carbon, were situated along the sides, and particularly at the back part of the trachea; which, from their size, must have interfered by pressure both with respiration and expectoration. the mucous membrane of the left bronchus in particular was much swollen and partially ulcerated towards the root of the lung. in examining the heart after its removal from the body, it was found peculiarly large and flabby, its cavities considerably distended, especially the right auricle and ventricle, while the valvular structure seemed natural. the pericardium contained about 10 ounces of straw-coloured fluid. after examining the organ particularly, i could discover nothing abnormal, but the enlarged and softened state alluded to. the liver was large and highly congested with dark thick blood, but otherwise it was healthy. the gall-bladder was empty, and the spleen large and congested. the stomach was smallish and empty. the mucous membrane was smeared with a blackish, tenacious fluid, which, upon removal, appeared to be a portion of the expectoration. the structure, as far as could be ascertained, was healthy. the small and great intestines contained fluid carbon (evidently swallowed), while no disease was manifest. the mesenteric glands were small and rather firm, but they contained no black matter; the mesentery was much congested with dark venous blood. the kidneys were apparently healthy, though soft. the bladder was small and contracted. the head was not examined, as i expected nothing but general congestion of the vessels. this case comes under the third division of the disease, where the lungs were cavernous, and where there was free expectoration of carbon. case 2. the following case is one of unsuspected carbonaceous accumulation in the lungs, the history of which proves the fact, that the disease, when once established in the pulmonary structure, continues to advance till it effects the destruction of the organs, although the patient has not been engaged in any mining operations for many years previous to his death. robert reid, aged forty-six at his death, had been a collier since his boyhood. he was a short, stout-made man, of very healthy constitution, and never knew what it was to have a cough. he spent the early part of his life at a coal-mine, near glasgow (airdrie), where he all along enjoyed good health. in 1829, he removed from airdrie to the coal-work at preston-hall, mid-lothian, where he engaged in mining operations; and, from the time he made this change, he dated the affection of which he died, at the end of 1836. two months after he removed to preston-hall colliery, he was seized with bronchial affection, giving rise to a tickling cough in the morning and when going to bed, accompanied by dyspnoea, with a quick pulse (90), and palpitation of the heart. in the first stage of the affection, he had no expectoration of consequence; but soon after, a little tough mucus was coughed up, and when it was difficult to expectorate, the sputum was occasionally tinged with blood. at this period, the appetite continued to be good, and the strength little impaired. during the day, he felt in his usual health; and, therefore, he continued in full employment. at the end of the four months (jan. 1830), his cough had increased much, his palpitation of heart, dyspnoea, and bronchial irritation had become very oppressive, and general exhaustion had manifested itself. recourse was had at this period of the affection to bleeding, blisters, and expectorants, which relieved him only temporarily, and while under this treatment, he--having a large family dependent on his exertions for their support--continued to struggle on at his daily vocation so long as he was able to handle the pick-axe. at the close of 1832, which completed three years of labour in this coal-mine, he was obliged to discontinue all work, and take refuge in medical treatment, with a severe cough, palpitation, annoying dyspnoea, small intermitting pulse, and sleepless nights. on inquiring as to his general habits and mode of life, i found that he had been all along a sober, regular-living man, that he never complained of ill health till he engaged in this coal-mine at preston-hall, where the work was difficult and the pit confined, he having only twenty-four inches of coal seam which obliged him to labour lying on his side or back.[10] he was also at this time occasionally engaged as a stone-miner, and was consequently subjected not only to the inhalation of the smoke of linseed oil, but to that of gunpowder. for his chest complaint at this stage, he underwent a variety of medical treatment, which produced mere palliation in his symptoms, and though breathing a pure atmosphere in a country situation, he experienced a most painful sensation of want of air, or, as he himself expressed it, "a feeling as if he did not get enough down." by this time the countenance had become livid, the lips and eyelids dark and congested. after undergoing medical treatment in the country, without much relief, he was removed to the edinburgh infirmary, in july 1833, in the hope of deriving benefit; but after being a patient in that hospital for some weeks, he returned home much worse. in addition to the aggravation of his other symptoms, there were present oedematous swelling of the extremities, which were generally cold and benumbed, gnawing pain in the right hypochondriac region, and almost total loss of appetite. on examining the right hypochondrium, which he described as swollen, there was evident indication of an enlarged liver, and he complained much of shooting pain in that region during a paroxysm of cough. hitherto the functions of the stomach and bowels had remained unimpaired; but at this period, (september 1833,) the former became irritated, and the latter obstructed. tonics and gentle purgatives were administered, and continued for a considerable time. the urinary secretion was all along scanty and high coloured; but, as the disease advanced, the quantity became exceedingly small, (almost none was voided for days together,) for which he was taking diuretics; and on examining it with the application of heat, i repeatedly found it coagulable. general anasarca was now rapidly increasing; and as the cellular effusion advanced, the breathing became more laborious. i understand, that at the commencement of this person's affection, the pulse was frequent, with some heat of skin at night, but from the time he became my patient, there was a tendency to languor in the circulation, and the _beat_ at the wrist, for some months previous to his death, was almost imperceptible. with a view to remove the enlargement of the liver, a slight mercurial course was proposed; but owing to debility, indicated at its commencement, it was discontinued, and no effect produced on the organ. all medical treatment having been given up, except mere palliatives, such as blisters and expectorants, this poor man lingered out a most miserable existence from his pectoral symptoms, and particularly from palpitation of heart. expectoration continued the same, of tough, ropy mucus, small in quantity, and got up with difficulty from the air-passages. in repeated examinations with the stethoscope, there was considerable dulness over the whole thoracic region, no bruit whatever could be discovered in the left side of the chest, no cavernous indication, although that side of the thorax was fully developed. the mucous râle was heard very strong in the upper lobe of the right lung, and some little crepitation at the inferior angle of the scapula on the same side. the action of the heart under the stethoscope gave rather an uncertain indication as to the state of that organ, for though the sound was evidently communicated to the ear, as being transmitted through a fluid, and not the heart striking the ribs, still, from the very general dulness in the left side of the chest, it was exceedingly difficult to decide whether this obscurity arose from effusion into the pericardium, or from effusion into the cavity of the chest. there was one remarkable symptom manifested in this case,--that though the heart's action was to the observer feeble, the patient's sensations were as if the pulsation was very strong, and painfully difficult to bear, and this peculiar feeling to a great extent prevented him from sleeping. i cannot record this case without the painful recollection of this poor man's sufferings. for six months previous to his death, the dyspnoea and palpitation attendant upon his disease were of such a severe character, as to prevent him at any time lying down; and his sensations would not even permit his maintaining the sitting position, for he found it necessary to get upon his hands and knees, as the only posture affording any alleviation to his uneasiness. this peculiarity in the cardiac action was such, that, as he expressed it, "he lived in continual dread of death," and this being ever present to his mind, he was for weeks known almost never to close his eyes. he died exhausted, in november 1836; and there being doubts entertained regarding some of the symptoms of his disease, he requested that his body should be examined, which was done twenty-six hours after his death. _post-mortem examination._--the general anasarca gave the body a bulky appearance. on raising the sternum, the ribs seemed very firm and unyielding. the lungs were of a dark blue colour, and seemed at first appearance to fill completely both sides of the chest. towards the sternal end of the ribs, on the left side, three or four of the substernal or mammary glands were found enlarged and filled with black fluid. the pleura pulmonalis had (where there wore no adhesions) interspersed over it patches of false exudation, _of a dark brown colour_. the lungs adhered extensively to the pleura costalis, and from the character of the adhesions, they were evidently of some years' standing. in both sides of the chest there was effusion to a considerable extent of a dark-coloured fluid, resembling porter in appearance. on removing the left lung, which was difficult, from the strong adhesive bands, it seemed, from its weight and softness, to contain a fluid; and on making a longitudinal section of both lobes, a large quantity of thick, black matter, similar to black paint, gushed from the opening, exposing an almost excavated interior of both lobes. the carbonaceous matter contained was in quantity about an english pint, and the lung, when emptied, became quite flaccid, and very light. the air-cells of this lung were entirely destroyed, or nearly so, and one of the divisions of the left bronchus opened abruptly into the cavity at the upper part. both lobes were so completely adherent to each other, from inflammatory action, as to form a continuous sac, containing the above fluid. on examining the internal structure of the cavity, the parenchymatous substance which formed its walls presented a rugged and irregular appearance, resembling a sponge hollowed out, and infiltrated with black paint. at different points, the large pulmonary blood-vessels crossed the cavity in the form of cords, with portions of structure attached, and though these fragments had a black appearance, they exhibited, to a considerable extent, their original cellular structure when washed in water. the process of carbonaceous ulceration had proceeded so far in this lung, that at some points the pleura pulmonalis, which was much thickened, was left the sole medium between the contents of the sac and the cavity of the chest; while in other parts it was thick and spongy. on examining more minutely with the magnifier, open-mouthed bronchial twigs, and very small blood-vessels, were seen plugged up with solid and fluid carbon, and, from the appearance of the morbid structure, it was manifest, that the ulcerative process had effected a complete disorganization of the _bronchial_ tubes of every calibre, while the smaller _arterial_ vessels had alone suffered, leaving the larger ones entire.[11] along the margin of the inferior lobe, indurated accumulations were felt through the pleura, and, on being laid open, they were ascertained to be impacted lobules, which resisted the knife. previous to the division, both lungs weighed about six pounds. on examining the right lung, which seemed much similar in weight to the left, and on making a section throughout its three lobes, the morbid appearances varied in each. the upper lobe was infiltrated with carbon into the interlobular cellular tissue, leaving the bronchial ramifications respirable, and lubricated with frothy mucus. the middle lobe presented a solid appearance, and contained a mass of indurated black matter, of the size of a largish apple, and consistency of consolidated blacking. the surrounding parenchymatous substance was disorganized, and undergoing the process of softening. in dividing the indurated substance, its internal structure exhibited a variety of greyish lines, forming parallel and transverse ramifications, which resembled small check in appearance, and which, when more accurately examined, was ascertained to be the disorganised walls of the minute air-cells and cellular tissue. the inferior lobe presented a state of complete infiltration, with the air-cells generally entire, and on putting a piece of it into water, it showed its density by sinking. when we examine the morbid appearances in this case, and compare them with the symptoms--when we consider that nearly all the respiration carried on in this man's chest, was performed in the upper lobe of the right lung, we are not surprised at his sufferings, nor is there much difficulty in explaining the very painful dyspnoea, on his attempting the recumbent position; and as death was instantaneous, it was evident that the immediate cause was the bursting of the left pulmonary cyst into the corresponding bronchus; the fluid carbon thus finding its way to the trachea, produced suffocation. the liver was exceedingly large, projecting outwards and downwards from under the ribs, and pushing up the diaphragm. its substance was soft, engorged with dark blood, and easily torn. there was no carbonaceous deposit throughout its structure, and its weight was upwards of twelve pounds. there was a considerable quantity of very dark bile in the gall-bladder. the heart was large, soft, and pale. there was considerable attenuation of the walls of both auricles and ventricles. the coronary veins were much distended with dark blood. the columnæ carneæ of the right ventricle were exceedingly slender and bloodless; the tricuspid valve was much thickened, and studded on both sides with small cartilaginous granules; the other cavities of this organ were apparently healthy, though thin in substance. the pericardium, which was rough, and much distended, exhibited a variety of false membrane on its internal surface, of a dark brown colour, and contained about eight ounces of dark fluid, similar to that found in the cavity of the pleura. in tracing the bronchi from the lungs to the bifurcation, the mucous membrane, which was smeared with fluid carbon, appeared much irritated, and considerably thickened, diminishing the diameter of these passages; and there were found externally at the root of the lungs, and around the bronchi, several large glands, containing a fluid to all appearance carbonaceous. the trachea showed a similar irritated condition with that of the bronchi. a little above the bifurcation, and at the back part of the trachea, a cluster of lymphatic glands were found, some of them the size of a horse bean, filled with carbon. _the spleen_ was very large, and much darker than usual, highly congested with venous blood, easily torn with the fingers, and weighed about three pounds. kidneys small, pale, and soft; bladder small, and corrugated; large accumulation of light brown fluid into the cavity of the abdomen, to the extent of two scotch pints. the viscera were much compressed from effusion. there was a rough brown exudation upon the surface of the peritoneum and intestines. the stomach was contracted to a small size. the mucous membrane was soft, pultaceous, and easily removed, tinged with dark green bile. the lymphatic glands along both curvatures were small and flaccid, and contained no black matter. the intestines appeared empty and contracted. the duodenum showed the same softened state of its mucous membrane as was exhibited by the stomach. the mesenteric glands were free from any disease. the head, on removing skull-cap, dura mater found natural; serous effusion to small extent under the arachnoid; very general congestion of the pia mater, giving both hemispheres of the brain a blackish appearance. the superior longitudinal sinus was filled with dark, inky-looking blood. in removing the pia mater, the convolutions of the brain were firm, and appeared natural. there was a light brown effusion into both lateral ventricles to the extent of about an ounce. reid, when he first came to preston-hall, had inhaled the evolved smoke of the coal-mine, thereby laying a foundation of this infiltrated mass. it must be manifest to every one who follows out the history of this case, and attends to the morbid appearances found within the chest, that there was a progressive accumulation of carbonaceous matter going on in the substance of the lungs from the time the patient engaged in working this difficult seam of coal till his death. * * * * * case 3. d. s. was aged 39 years at his death, in august 1838. he had been engaged as a coal-miner so soon as he was able to undertake work. he was a tall, muscular man, and for a long time enjoyed excellent health. he first began mining operations at one of the pencaitland collieries, and continued to labour there for many years. about six years before his death, he was induced by an increase of wages, to undertake stone-mining in the same pit; and soon after engaging in this employment, he began to be troubled with a slight cough, accompanied by dyspnoea, palpitation, and oppressive headach, which symptoms rapidly increased in severity. he declared that his cough and general ailments first showed themselves after labouring for a considerable time at stone-work, with the aid of gunpowder, in a situation where the air became so impure, both from defective ventilation and carbonaceous particles floating in it, as materially to affect the breathing. although he repeatedly changed his place of labour from one coal-work to another more healthy in the same parish, he experienced no mitigation of his annoying cough. when i first saw this man for medical advice in july 1834, he had then been about two years engaged as a stone-miner, the bronchial irritation was very general throughout the chest, he had severe cough, hurried breathing, little or no expectoration, and on applying the ear to the thorax, the sibilant and sonorous bronchi were distinctly heard, which indicated a swollen and irritated condition of the mucous linings of the air-passages, and this irritation was also manifest in the mucous membrane of the nostrils, which was much swollen, acutely tender, and impeding considerably the passage of the air. the pulse was rather frequent, about 85 in the minute. there was present much heat of skin during the night, which subsided towards the morning. the remedial measures were blisters and expectorants, which relieved him considerably. the cough recurred in paroxysms, accompanied by severe headachs, with little frothy mucous expectoration, and there was occasionally observed a slight tinge of blood in the sputum. at this period, his appetite was good, and with the exception of his cough and difficulty of breathing at night and morning, he seemed usually very well. though labouring under his disease, he continued at his employment of stone-mining, and would not be convinced of its injurious effects. _july 1835._ there was considerable increase of the palpitation when he attempted the recumbent position, or moved hurriedly. the remedies ultimately seemed to produce little effect. his general exhaustion advanced rapidly, and obliged him to relinquish all mining occupation. at the end of the summer of 1836, when i saw him more regularly, and was enabled to watch his symptoms with more attention, these having materially changed for the worse, percussion elicited dulness over the chest, with the exception of the upper part of both lungs, where the mucous râle was heard louder than usual. the heart's action was strong and irregular, particularly so for some time after a fit of coughing, when he suffered excessively from headach, succeeded by a tendency to drowsiness. the pulse was slow and languid, not exceeding 50 in the minute. his countenance had assumed a greyish inanimate aspect, his eyes became sunk, his robust frame bent and so emaciated from this peculiar disease, that though his age did not exceed 38 years, a stranger looking at him, supposed him to have attained the age of 70. no treatment seemed to have any effect in allaying the cough, nor was he permitted to lie down. from his feeling of dyspnoea and thoracic oppression, his nights were almost sleepless, his extremities oedematous, usually cold and bloodless. during the greater part of the time he was confined to the house, the bowels were constipated, requiring daily purgatives. the urinary secretion was small in quantity and high coloured, but in neither discharge was there any thing very unnatural. in this almost inanimate condition he lingered on, when about six months before his death, during a paroxysm of cough, he expectorated a mouthful of thick black matter, and continued so to do periodically, at intervals of about three weeks, seeming to experience relief after voiding the carbonaceous sputum. there was little change in the symptoms of this man till death. he took little or no food, from his appetite being almost entirely gone, and from gastric irritation being constantly present. his cough and dyspnoea continued severe, with drowsy headachs and difficulty in keeping the body warm. the arterial action was exceedingly low. the pulse was 40 in the minute, and difficult to discern. the strongest stimulant produced no increase of action, the sitting position was the only one in which he was at all easy, and in which he remained day and night till he ceased to live. _post-mortem examination, twenty-four hours after death._--the body was much emaciated. the chest large, and integuments tightly drawn over it, the ribs unyielding. in removing the anterior part of the chest, the lungs adhered strongly to the ribs, and were covered very generally with patches of dark-red false membrane, corrugating the pleura. each side of the thorax contained fully a pint of light-brown fluid. in removing the left lung, it felt firm and developed, and in dividing it throughout its lobes, a variety of small cavities and indurated masses of carbon were found to pervade its substance, exhibiting a sooty appearance, extending throughout the whole structure. the indurated nuclei were ascertained to be impacted lobules, and the small cavities were these disorganized and softened, and communicating with the bronchial tubes. part of the upper, and the whole of the inferior lobe, were soaked with carbon, and felt indurated. the right lung was similarly disorganized with the left. the greater part of the superior lobe was permeable to air, and the interlobular tissue contained carbon, in small, hard granules. the middle and inferior lobes contained several hard, indurated bodies, progressing to a state of softening, and in separating a portion of the latter lobe, it was found to sink in water. there was emphysema of the margin of the inferior lobes. there appeared considerable irritation and softening of the mucous membrane of both bronchi, extending from the root of the lungs to beyond the bifurcation of the trachea. there were several enlarged bronchial glands at the apex of the lungs, containing black fluid. the pericardium contained about eight ounces of straw-coloured fluid. there was a light-brown exudation, extending over serous lamina of the pericardium and the surface of the heart. the heart was flaccid, the right auricle and ventricle were enlarged and attenuated, and both vena cava at their junction with the heart were much dilated, the valvular structure natural. the liver was large, soft, and easily torn. the abdominal viscera in general appeared healthy; slight effusion into the cavity of the peritoneum. in this case head not examined, but which no doubt would have shown marks of extensive congestion, as in other cases. the above case comes under the second division of this disease, where the irritative process resulting from the foreign body pervading the lungs, had advanced so far as to produce a variety of small cysts, and circumscribed, indurated masses, the former containing _fluid_, and the latter _solid_ carbon, and it is evident in tracing its progress, that there must have been a very rapid increase within the system in the carbon originally deposited in the pulmonary structure by inhalation. there was very limited black expectoration shortly before death, and this merely the contents of a few small cavities communicating with the bronchial ramifications, while both lungs were extensively infiltrated with that matter which, had the patient lived, would have produced general softening, and more extensive excavations by the coalition of the various indurated tubulæ. * * * * * case iv. j. t., aged 45 when he died, may 1837. he became a collier in early life, in the neighbourhood of glasgow, and came, at the age of 22 years, to east lothian, to engage in collier labour at blind wells, near tranent. from his own account, he was rather of a delicate constitution, and ill-fitted for the work of a coal-pit, consequently, after labouring a few years, he was, at the age of 26,--owing to cough and difficulty of breathing,--obliged to relinquish the employment of a miner. he left east lothian, and retired to the west of scotland, where he became a country merchant, and continued so occupied for upwards of fifteen years. during that time, he was occasionally troubled, particularly in the morning, with his cough and hurried breathing, which was increasing in severity, but at no period had he expectorated black matter, nor was there any indication that his sufferings arose from carbonaceous disease. on account of becoming reduced in circumstances, he was under the necessity, though labouring under chest affection, of returning to his former employment of coal-mining at blind wells, at the age of 41, august 1834. he had not been long engaged as a miner, after his return to east lothian, when his cough increased considerably, with laborious breathing, palpitations, and overpowering headach. both now and formerly, he wrought solely as a coal-miner, and at no time of his life did he work as a _stone-miner_. having a family to provide for, he struggled on laboriously under much suffering from his chest affection, till general exhaustion compelled him to leave off work, and seek regular medical advice, july 1836. from his statement regarding the cause of the disease, i was led to understand that his cough, which never left him from the time he was first seized, was induced, at an early period, by bad air generated in the coal-pit at black wells, from the work being ill ventilated, and from the general use of coarse linseed oil for the lamps. when i first saw this man professionally, he was labouring under general weakness; his pulse was not above 40 in the minute, small and thready. he suffered from drowsy headach, anorexia, cold and slightly oedematous limbs. he had incessant cough, with tough mucous expectoration. during a severe paroxysm, he vomited a mouthful of black paint-like fluid, followed by considerable relief, and ever after till his death, he continued to expectorate the same substance in great quantity, often to the extent of 15 oz. daily. in examining the chest with the ear, the sound, from the distinct pectoriloquy, indicated a cavernous state of both lungs; otherwise the bruit was obscure. the remedies were merely of a palliative character, knowing the patient to be rapidly sinking. in this exhausted state he remained for some months; his appetite was almost entirely gone; the oedema of limbs increasing. there was also a leaden hue over the surface of the body, which was constantly cold. at this stage, the quantity of urine voided was small and dark in colour. bowels obstinate; occasional vomiting. the pulse ranged from 38 to 40. the lips and ears were livid, and his drowsiness became more overpowering as death approached. _post-mortem examination._--the body was much emaciated; the ribs were prominent and unyielding. on removing the anterior part of the thorax, the lungs were found firmly adhering to the pleura costalis, and of a dark blue colour. there was an effusion to the extent of about sixteen ounces of light-brown fluid, found in the cavities of the pleura. the greater part of the effusion was into the left side. the lining membrane of the chest was almost wholly covered with false membrane of a dark brown colour. the right lung filled almost completely the right cavity of the thorax, while the left lung appeared much contracted, particularly towards the apex. the pleura of both lungs was much puckered, and interspersed with dark red patches around the adhesions. three or four of the substernal glands were found considerably enlarged, and filled with black fluid, and a cluster of the anterior mediastinal and lymphatic glands contained fluid having the same appearance. the right lung appeared solid to the feel, when removed from the body. it was rough and irregular over its surface, from a variety of indurated substances projecting from beneath the pleura. in making a section of the whole lung, each lobe was almost completely saturated with thick inky fluid, and was observed to be here and there hard and granular, particularly in the course of the larger bronchi. portions of this lung were pervious to air and emphysematous, but the greater part was disorganized, and contained carbonaceous matter in a solid and fluid state. the left lung was light and flaccid, when compared to the right. the upper lobe was extensively excavated. the parenchymatous substance was found ragged and unrespirable, and many large blood-vessels crossing from either side of the cavity, pervious to blood. with the aid of the magnifier, a variety of open-mouthed bronchial twigs and minute blood-vessels were visible, communicating with the cavity. the upper part of the inferior lobe was partially excavated, and containing about four ounces of fluid carbon. the lower margin of this lobe was firmly impacted. the mucous membrane of the trachea and bronchial divisions appeared, when washed and freed from the black matter, red and softened. the lining membrane of larynx was partially ulcerated, and the rima glottidis slightly oedematous. there were various small lymphatic glands on the back part of the trachea, which contained black fluid. the pericardium considerably distended, and contained nearly twelve ounces of light-brown fluid. evident marks of inflammatory action were observed externally. on its internal surface it was thickly coated with false membrane of a brown colour. the heart was pale, soft, and attenuated. the right auricle was much dilated, and its walls exceedingly thin. there were no further morbid appearances. head,--external congestion of an inky colour was found on the surface of the brain, which was to all appearance otherwise healthy. there was an effusion into both lateral ventricles. the abdominal viscera were natural. the liver was much larger than usual, soft, and highly congested with inky-coloured blood.[12] it is evident, from the symptoms and history of the above case, that the patient had contracted the disease of which he died at an early period of his life, and that during the fifteen years he refrained from mining operations, the pulmonary structure retained the carbon inhaled while labouring in the coal-pit, and this is one of the many cases which can be produced as examples of the fact that the foreign matter once deposited in that structure originates a process of accumulative impaction and ultimate softening of the organ, which is gradually carried on till it is entirely disorganized. this case comes under the third division of the morbid action, viz. where extensive excavation of the structure is produced. * * * * * case v. a. g., aged 52 at his death. he was a collier from his boyhood, and wrought during the greater part of his life at penston colliery in the parish of gladsmuir. he was a short-set robust man, and while labouring at penston, he enjoyed usually good health, free from cough or any affection of the chest. when he had attained the age of 48 years, (1833), he removed from the penston to the pencaitland coal-work, and about six months after making this change, he began to experience a slight difficulty of breathing, accompanied by a troublesome cough and feverish nights. the pulse was 84. various soothing remedies were administered, which relieved for a little the pectoral symptoms; and as he felt no decided physical debility, he continued as usual at underground work. in 1835 i saw him often, and found that his pulmonary symptoms were becoming more marked; his cough was excessively annoying in the morning and when going to bed; his expectoration was frothy mucus, with dyspepsia, palpitation, and occasional headach. the resonance of the chest on percussion was very slightly impaired, and the respiratory murmur was variable, being occasionally louder at one time than another, and often much obscured, from the mucous secretion. labouring under this chest affection he still continued his daily employment till the spring of 1836, when he was entirely laid aside, being unable to go below ground, or to take the slightest fatigue, for the smallest exertion produced a fit of coughing; and during a paroxysm of this kind, he expectorated a few black sputa, which in a few days disappeared, and gave place to the usual frothy mucous expectoration. this bronchial discharge was accompanied by considerable relief to the cough and dyspnoea. by this time, (june 1836), on applying the ear to the chest, the resonance is dull, and respiratory murmur obscure. the action of the heart was slow when compared to its former state. the pulse not beyond 45 in the minute. by the end of this year he appeared in a half dead state,--but a mere shadow in regard to flesh. he was expectorating at intervals of some weeks, when the cough became more severe, a few carbonaceous sputa, and suffering severely from gastric irritation.[13] during the last week of his life, he expectorated considerable quantities of black fluid, and died exhausted, january 1837. _post-mortem examination_, which was conducted hurriedly, exhibited extensive effusion into both sides of the chest. the adhesions of the pleura were strong, and evidently of long standing. there was very general carbonaceous infiltration throughout the lungs, without excavations to any extent. various empty cysts, which could contain a hazel-nut, were found in the superior and middle lobe of the right, and throughout the whole of the left lung; in which bronchial twigs terminated. the pericardium was distended, with limpid effusion. the right side of the heart was dilated, and filled with dark treacly-looking blood; and when washed, it appeared pale and bloodless. its walls were thin, various patches of brown exudation extending over both pleuræ. there were several enlarged lymphatic glands, found at the root of both lungs, filled with black fluid. in examining the head, the pia mater was found much congested; but there was no effusion discovered into any of the ventricles of the brain, nor any other indication of disease. in tracing the history of this patient, connected with the disease, it will be observed, that until he came to pencaitland colliery, he had no symptom whatever of chest affection. penston coal-work is exceedingly well ventilated, and the miners who labour there seldom, if ever, suffer from the black expectoration, owing to the evolved smoke of every kind being freely carried off from its underground works, while it is quite the contrary at pencaitland, where many colliers, on leaving penston, are seized with the disease. this case comes under the second division of the disease, where the irritative process, the result of the foreign matter in the lungs, has proceeded so far as to produce a variety of small cysts, containing fluid, or semi-fluid carbon, following the course of the bronchial ramifications. * * * * * case 6. d. l., aged twenty-six years at his death, in august 1837. he was the son of a collier, at pencaitland, and engaged at an early age in putting the coals to his father; and when he was fit for full collier-work, in 1831, he was employed at the same coal-work. he was a tall, well-formed, robust young man, and not at all liable to chest affection. for some time he wrought, as a coal-hewer, but latterly was induced, (1834), for higher wages, to become a stone-miner in the same coal-pit, where gunpowder was used extensively in the operations. about six months after he commenced stone-mining, he became affected with a short tickling cough, expectoration of pearly tenacious phlegm, hurried breathing, tightness across the chest, frequent pulse (95), heat of skin during the night, and occasional throbbing in the head. being young, and fearless of any danger from the occupation, although warned of the consequences, he continued to prosecute it, and twelve months (may 1835) after he first began, the cough had increased much in severity. the expectoration was diminished, and had become more difficult to void from the bronchi, and the breathing was more oppressive, accompanied by a painful tightness across the chest in the morning. the body was considerably reduced in bulk to what it previously had been. the pulse ranged from 80 to 90; the appetite was impaired, and there was in the morning a tendency to retching. the nocturnal heat of skin continued, without any moisture, though his body was drenched with a clammy sweat during the hours of labour. the respiratory murmur was harsh and extensive at the upper part of both lungs, while the sibilant ronchus was heard occasionally in the lower lobes. the heart's action was regular, but impulse strong, on applying the hand to the cardiac region. the remedies resorted to were blisters, bleeding (at an early stage), expectorants, and tonics, which, to a certain degree, relieved the more urgent symptoms. in october 1835, the disease having made rapid progress, all the symptoms had become more marked. the cough, from its frequency and severity, was extremely exhausting, and the expectoration had become more copious, and of a semi-black colour. the mucous râle was evident in the upper part of both lungs, while the inferior lobes were dull to the ear, and on percussion. the heart's action, at this stage, was less strong, but no peculiarity in its function could be discovered. the cardiac region exhibited every indication of effusion into the pericardium. his body was now considerably emaciated, and the anterior part of his chest was so much contracted, as to oblige him to stoop to a great degree. under this load of disease, he continued his employment of a stone-miner, gradually losing flesh, with a rapidly increasing black expectoration; and having several dependant on his exertions, he resolved to work, while he could keep on foot, which he did till september of the following year, (1836) when his once powerful body was so reduced, from disease, and his cough so incessant, that he was unable to move or speak without great fatigue. he preferred the sitting position, as giving him most freedom in breathing. the pulse was rather slow and small; the heart's action languid, and there was an evident increase of dulness upon percussion over cardiac region. at this, the closing period of the disease, (november 1836) he first complained of drowsiness, accompanied by headach. the countenance was pallid; the eyes sunk and inanimate, and the body tending to be cold; the urinary secretion of a dark brown colour, and precipitates a dark deposit. the bowels were exceedingly obstinate, with little change in any of the symptoms; he lingered till january 1837. _post-mortem examination._--the body was much emaciated. the thorax was large, and well arched. on removing the anterior part of the chest, the lungs appeared to be fully developed, and of a dark blue colour. there were several very slight adhesions between the pleuræ, and the effusion into both cavities was small in quantity. the pleura costalis was almost free from any exudation, but there were a variety of small patches of false membrane throughout the pleura pulmonalis. the left lung exhibited general carbonaceous infiltration. the upper lobe was partially excavated. the pulmonary structure, internally, was ragged and easily torn, and these cavities communicated with the bronchial divisions, the walls of which formed various septa. the inferior lobe was almost impervious to air. the minute bronchial ramifications and corresponding lobules were impacted with dense carbon. there were several clusters of small cysts throughout this lobe, containing carbon in a fluid state. a portion of this lobe sank in water from its density, and when squeezed with the hand, thick fluid carbon, containing hardened particles, could be expressed from it. the right lung was similar in external appearance to the left. the upper lobe was crepitant, though infiltrated with carbon into the interlobular cellular tissue. the air-cells were gorged with tenacious mucus. the middle lobe was partially excavated. the cellular tissue was considerably disorganized, and similar in diseased structure to the upper lobe of the left lung, with the exception of a portion affected by vascular emphysema. the inferior lobe was much condensed, and loaded with carbon of a very bright black. the mucous membrane of the bronchial tubes was thickened, and slightly ulcerated. various lymphatic glands were found at the root of both lungs, containing black fluid. the pericardium was considerably distended from effusion of a straw-coloured fluid. the internal surface of the pericardium was rough, and both laminæ appeared thickened from inflammatory action. effusion into cavity of chest to the extent of twelve ounces. the heart was natural in appearance, but thin in substance. the tricuspid and mitral valves were thickened, and exhibiting minute granulations on their surface. the right auricle and ventricle were dilated considerably. aorta, and other vessels proceeding from heart, were natural. the stomach was small, and exceedingly spongy in its mucous lining. the intestines were healthy. the kidneys were small, and peculiarly yellow in the internal structure. the liver was large, and engorged with dark thick blood; several small carbonaceous cysts throughout its substance. the spleen was large, soft, and much congested. the mesenteric glands free from black matter. _head._--the arachnoid thickened and opaque; there was very general congestion of pia mater with dark black blood, and when removed, convolutions studded over with innumerable dark points. the surface of the brain was apparently healthy, with an effusion of a light pink-like fluid into the lateral ventricles. the internal substance of the brain natural. this case is interesting, as showing the very rapid course, in some instances, of the disease to a fatal termination, and also how soon the strongest man can be brought under its destructive influence. this is the only case in which carbon was discovered in any of the other organs, as exhibited in the liver. the above case comes under the third division, showing extensive excavation of the pulmonary structure. case vii. james r. aged 54 at his death, 1836. he was a large muscular man, and wrought as a coal-miner in early life at pencaitland, and, as far as could be ascertained, he had never been engaged at stone-mining. at the age of thirty he was obliged to desist work, on account of a difficulty in his breathing, which he considered to be asthma, and he was occupied above ground, as the engine-man, during the latter part of his life. the slightest exertion produced exhaustion and palpitation of the heart; his bowels were obstinate, and his urinary secretion small in quantity. his cough was particularly troublesome in the morning, and was relieved by a free expectoration of frothy mucus. in this condition he continued, with the cough gradually increasing, for nearly twenty years, as i understand, when he began to void black sputa, which daily augmented in quantity till his decease, august 1836. for some weeks previous to his death, his pulse had become slow and thready, 36 in the minute. the oedema of the upper and lower extremities was extensive; the dyspnoea increased considerably; the countenance was livid; and the body remarkably cold. stimulants in considerable quantity were administered without the smallest effect. drowsiness supervened; and he was for some days previous to dissolution in a torpid condition, while at the same time he was quite collected when roused. _post-mortem examination._--on examining the body, the chest was large and well formed. the effusion into the cellular substance was very general. the cartilages of ribs were ossified, and both lungs were adhering strongly to the pleura costalis. there was large effusion into both cavities of the chest, to the extent of three english pints in whole. the pleura pulmonalis was much thickened and rough, with false membrane, and many patches of puckering. several lymphatic glands in the anterior part of the mediastinum contained black fluid. the left lung was carbonaceous throughout its substance. the upper lobe partially excavated and ragged; the inferior lobe infiltrated and emphysematous. the right lung was of corresponding black appearance. the lower lobe had a firm and condensed feel, and when divided, exhibited a mass resembling indurated blacking. the middle lobe was in part permeable to air; and there were several small cysts containing liquid carbon, connected with minute bronchial ramifications. various indurated knotty bodies were extended throughout its substance. in the upper lobe, the carbon was confined principally to the interlobular cellular tissue, and when pressed in the hand, gave out thick, black, frothy serum. the mucous membrane of bronchial divisions, when freed from the black matter, was swollen and eroded as far up as the bifurcation of the trachea. at several parts these passages were considerably contracted. the heart was enlarged, and dilated in all its cavities. the valves of the right and left ventricles wore thickened, from congestion of very minute veins, and were granular to the feel. the substance of the heart was soft. there were eight ounces of effusion into the pericardium, resembling that formed in the cavities of the thorax. the liver and the spleen were large; the former peculiarly yellow and oily. several very large veins, containing inky-looking blood, were seen ramifying its substance. the spleen was very friable. the kidneys were small, and apparently healthy. brain not examined. this case comes under the third division of the disease. r.'s case is peculiarly striking, from the length of time (twenty years or more) that the carbon was concealed within the pulmonary tissue, and also because he had never been engaged, as far as known, as a stone-miner; so that this case, along with others, illustrates the fact, that where the morbid action is the result of lamp smoke, from the combustion of coarse oil, and not gunpowder smoke, the disease is much slower in its progress, but ultimately fatal. * * * * * case viii. r. d., aged 37, at his death, 1839. he was the brother of george davidson, subject of the first case in this essay. he began to labour as a miner, with his brother, in early life, at pencaitland coal-work. he first began as a coal-miner, and after being so engaged for five or six years, he removed to penston coal-work, which adjoins. he continued healthy for a considerable length of time, and at his brother's death, december 1836, he was free to all appearance from any affection of the chest. he returned, 1836, to pencaitland coal-work, where he engaged as a stone-miner, knowing that such employment was destructive to life; and from that change he dated the commencement of his disease. cough, palpitation, dyspnoea, headach, quick pulse (90 in the minute), made their appearance, soon after he began trap labour, and these symptoms gradually increased, till he was laid aside in the course of two years, (1838,) when he first expectorated black sputum.[14] as his exhaustion advanced, the carbonaceous expectoration became more copious, and he discharged from the lungs at an average twelve ounces of fluid, resembling liquid blacking, daily; and he died in a manner similar to his brother, case no. 1. some weeks previous to his death, his pulse rapidly sank to about 45 or 50, and became exceedingly feeble;--cold extremities, oedema of the legs and arms, lividity of lips, eyelids, and ears, preceding dissolution. _post-mortem examination._--the chest was contracted; the ribs unyielding, with extensive adhesions of the pleuræ. both lungs were of a dark-blue colour, much puckered from patches of false exudation. there was extensive effusion into both cavities of the chest; and the right lung showed carbonaceous infiltration throughout its whole extent. the superior lobe was excavated, so as to contain a small orange; and about six ounces of thick, black matter were found in it. the middle lobe was crepitant, though soaked with black fluid; several impacted lobules were scattered throughout its substance. the inferior lobe was indurated, resembling a piece of moist peat. the left lung was cavernous in both lobes, and the cysts were empty, the contents having been expectorated. a small portion of the upper lobe was pervious to air. there were several enlarged bronchial glands at the root of both lungs; and the tracheal glands contained black fluid. the liver was large, and its substance soft. _head._--there was extensive congestion of the blood-vessels of the brain, with effusion into the lateral ventricles. the viscera of the abdomen were extensively congested, with slight effusion into the peritoneal cavity. it will be observed in referring to the history of this case, that till the time this man became a stone-miner, and carried on his operations with the aid of gunpowder, he had no symptom of the disease of which he died, and it is evident that the disease, if commenced at all, had made little or no progress till after his return from penston colliery to pencaitland, and after he had inhaled the residuum of gunpowder combustion, therefore the disorganization of the pulmonary structure was to all appearance effected between the summer of 1836 and december 1838, showing decidedly the very irritating character of gunpowder smoke upon the delicate tissue of the air-passages. case 9. j. d., aged 37, at his death, april 1844. he was a well formed man, with a fully developed chest. at so early an age as seven years, he engaged in the labour of the coal-pit at preston-hall, mid-lothian, and he continued to prosecute that employment for a period of 15 years, when he was obliged to relinquish the work on account of an affection of the chest, being, as he termed it, "touched in the breath." during the subsequent 15 years of his life, he had never once entered a coal-pit, nor had he any connexion with coal-works, but earned his bread by the trade of a travelling merchant. he had suffered much in his wanderings, from his breathing,[15] for more than two years continuously, while loss of appetite, and thoracic irritation, had rendered his physical frame as weak as that of a child. when i first saw this man, which was about a month before his death, he laboured under rending cough, with a scanty tough mucous expectoration--oppressive dyspnoea, ascites, general anasarca, occasional giddiness, and throbbing headach on motion, or on assuming the standing position. his countenance was of a light blue or slate colour, and his upper and lower extremities had much the same appearance. his lips, eyelids, ears, and nose, were swollen and livid, and his eye-balls effused, and apparently projecting from the sockets. his sight was impaired and hazy. there was continued feeling of cold, with occasional rigors, and difficulty in keeping the extremities warm. there was considerable exhaustion upon the slightest exertion. the half reclining posture was the only one in which he was comfortable. the pulse was exceedingly slow, not above 36 in the minute, it was small, and often imperceptible at the wrist. there was considerable weight and feeling of oppressive fulness in the region of the heart, which was dull on percussion. on applying the ear to the chest, little or no râle whatever was discernible, and the action of the heart was almost inaudible. he had a sensation as of great weight in the head, and difficulty in raising it. ho suffered from restless nights, short hurried breathing, with a feeling and dread of suffocation, evident fulness and enlargement in the region of liver, and inability to turn to the right side. the urine was small in quantity, of a bluish colour, and coagulable, irritability of stomach, and the bowels were obstinate and difficult to move, even with drastic purgatives. the treatment was merely palliative, no stimulant seemed to have any effect in exciting the system. ascites and general anasarca were considerable, giving the body a large appearance. for some days previous to his dissolution, there was increased lividity of countenance, and little or no action of heart. he had at no time expectorated carbon, even during many severe paroxysms of cough. upon inquiry, i found that this man had been a companion in labour to r. r. (whose case no. 2, is fully reported,) at preston-hall colliery, and from the morbid appearances found in r.'s chest, and from the character of the coal-work in which both were engaged, i was induced to believe duncan's to be a similar case. in ascertaining his early history, i found him to be a robust powerful man, though troubled with a cough and hurried breathing from his first becoming a collier, circumstances very usual with those who engage in difficult mining operations, and which they erroneously attribute to want of air, nothing more. _post-mortem examination, twenty-four hours after death._--the body was much swollen from effusion. on removing the anterior part of the chest, both lungs were much compressed from an immense effusion of a light brown fluid into the cavities of the chest to the extent of a gallon. the lungs were of a deep black colour, and irregularly spotted with dark brown patches of exudation. there were considerable adhesions of the pleuræ, and marks of very general chronic inflammation and false membrane over the greater part of the pleura costalis. there were adhesions of the left lung to the pericardium, which was much thickened, and contained about 14 ounces of a turbid fluid. on removing the left lung, it seemed large, and felt partially consolidated, and on dividing it throughout both lobes, it contained a mass of semi-fluid carbon, of a bright black colour, similar to paint. in this lung, the air-cells were almost entirely disorganized, unfitting it for the function of respiration. the upper lobe was divided into a variety of cysts, filled with carbonaceous matter in a fluid state, into which many of the smaller bronchi opened, and through which various blood-vessels passed uninjured. the inferior lobe, when emptied of its contents, was so much excavated that the parenchymatous substance felt light and flaccid. on dividing the right lung[16] it exhibited a pure black mass, but not so fully disorganized as the left. portions of each lobe were permeable to air, while other parts formed cysts, containing fluid and solid carbon, the inferior lobe showed an almost solid mass. the mucous membrane of the respiratory passages was inflamed and spongy throughout the divisions, the small ramifications were irritated and choked up with tough, frothy phlegm. there were several large bronchial glands at the root of the left lung. in tracing the divisions of the bronchi more minutely, from the root of the lungs into their substance, clusters of glands were observed filled with inky fluid, and narrowing considerably the air-passages, and in washing carefully a portion of the upper lobe of the right lung, and removing as far as possible the carbonaceous matter, several lymphatic glands were seen with the aid of the magnifier, imbedded in the interlobular cellular tissue, resembling small black beads. the tracheal glands when examined, contained black fluid, similar in appearance to what was found in the bronchial glands. the mucous membrane of the trachea was soft and irritated, smeared with tough bloody mucus, the lining membrane of the rima glottidis was thickened and slightly granular. the heart was much enlarged, and soft, with spots indicating chronic inflammatory action on and about the right auricle. both auricle and ventricle on the left side of the heart contained a deep-dark blood. there were several large lymphatic glands imbedded around the great vessels proceeding from the base of the heart, containing black fluid, the other cavities appeared healthy, though attenuated in substance. the coronary veins were congested. none of the cervical glands contained black fluid, though several of them were enlarged. the cavity of the abdomen much distended from ascites; the contained fluid was to the extent of about six scotch pints of a straw colour; the viscera much compressed, and matted together, with light brown exudation. the peritoneum was rough, and coated with the same exudation. the stomach and all the intestines correspondingly contracted; the mesentery appeared healthy; the liver was much enlarged, and darker than usual; the inferior lobe extending downwards, near to crest of ileum; the whole organ loaded with inky-coloured blood; the substance easily torn. the kidneys presented a natural appearance; the adipose substance in which they were imbedded was oedematous; the medullary substance of each presented a yellowish colour. _head._--the integuments were oedematous. on exposing membranes, considerable effusion under arachnoid; very general venous congestion, extending over the convolutions, and to the base of the brain. effusion into the lateral ventricles of a light yellow; the choroid plexuses thickened, and of a dark venous appearance; substance of brain firm and apparently healthy. from the history of this case, it will be found that d. had at no time shown any indication that carbon was infiltrated into the lungs. at an early age he came under the influence of the smoke of coarse linseed oil, and of gunpowder, while labouring in an unhealthy and ill-ventilated pit, which produced a cough common amongst colliers, who may be placed in similar circumstances; and it is evident, that during the last fifteen years of his life, the carbon--having previously taken up a lodgment in the pulmonary tissue--was gradually accumulating, and thereby producing painful dyspnoea, and the other formidable symptoms connected with the circulating organs, which followed as results, till it had almost entirely saturated the cellular structure, and rendered the lungs unfit for the functions of respiration, consequently impeding the necessary change, through the medium of that function upon the blood. there was a marked similarity in the morbid appearances between this case and that of reid, (no. 2). they both wrought in the same pit at preston-hall, and were affected in a similar manner. both had enlarged liver, and the left lung principally disorganised. both had extensive anasarcous and other effusions, and both had coagulable urine. neither expectorated black matter, and both died from the bursting of a carbonaceous cyst into the bronchi, producing suffocation. duncan lived longer under the infiltration than reid did; and this was no doubt owing to his being younger, and also his healthy occupation latterly. i have preserved a quantity of the contents of a cyst in the left lung of this patient, for chemical analysis; also a portion of the blood from the vena cava, and a little of the black fluid from the bronchial glands.[17] case 10. (the subject of the following case is still alive, 1845.) j. s., aged thirty-six. he was born of collier parents, in the parish of pencaitland, and at as early an age as eight years, went under ground to assist his parents in the transmission of the coal, and when fit for work became a coal-hewer. from his infancy he was rather of a delicate constitution, with flat and contracted chest. when i first saw him, which was about eight years ago, (1837), he was in full employment as a coal-hewer, complaining of shooting pains through his chest, tickling cough in the morning, with scanty tough expectoration, and frequent palpitations. he was repeatedly under treatment for bronchial affection, which was usually relieved by expectorants, blisters, and _continued_ counter-irritants. each attack of bronchitis was the result, as he expressed it, of "breathing bad air in the pit," in which he was obliged to relinquish labouring, as the lamp would not burn, from the state of the atmosphere. he never wrought at the stone-mining nor blasting. in examining the chest with the ear, at this stage of the affection, the mucous râle was distinctly heard, and exceedingly loud throughout the greater part of the chest. the heart's action was strong, but natural; pulse 70, full and bounding. about four years ago, he removed from huntlaw to blindwell, a coal-work towards the sea-coast, an extension of the same coal formation. at this time, 1841, he had very troublesome cough, particularly in bed, scanty frothy expectoration, annoying dyspnoea, preventing him taking sufficient nourishment, headach, obstinate bowels. he continued under all these ailments to labour with much difficulty, till the summer of 1843.[18] in reviewing the morbid appearances in the cases now detailed, it will be observed, that in the majority of them, the left lung exhibited the greater amount of diseased structure. this fact is particularly interesting, as in _tubercular_ phthisis, a similar predominance of disease is found on the left side. in almost all the cases, there was found very extensive effusion into the serous cavities, and particularly into those of the pleura and pericardium. both pleuræ were much thickened, and all the marks of a long standing pleuritic and pericardial inflammatory action were seen. the substance of the heart, in all the cases, was soft and attenuated; the right auricle and ventricle were dilated; and there was thickening of several of the valves. the liver and spleen were usually large and congested. in all the cases, as the disease advanced, the pulse came down to a very unfrequent and thready beat. from the great extent of the venous congestion, the disease often assumed the aspect of asphyxia; and in some instances the colour of the patients resembled that of persons labouring under cyanosis. the lividity of countenance, and the other concomitant symptoms, which presented themselves, gave decided indications of the morbid effects of this extraneous body. it requires little explanation to show how such a diseased state of the pulmonary organs, as has been described, should produce such results, by impeding the necessary chemical change of the blood. imperfect oxygenation of the blood, consequent on the altered pulmonary structure, must cause a general depression of all the vital organs. the excess of excrementitious matter in the circulation, must produce effusion of serum into the various cavities, and also into the cellular structure; and the appearances exhibited on the surface of the brain and its membranes, afford a full explanation of the sluggish inanimate condition of all the sufferers towards the close of their existence. from the cases above reported, it must be evident, that black phthisis is the result of foreign matter inhaled and retained within the pulmonary structure. it is a melancholy fact connected with mining occupations in the locality described, that few or none who engage in it, escape this remarkable disease. i have never known one collier in many hundreds, who, even in his usual health, was not, as he expressed it, more or less "touched in his breathing;" and after much experience in auscultation in such pulmonary affections, i am the more convinced that the dyspnoea from which they suffer, arises from impaction of the minute bronchial ramifications induced during their labour below ground, surrounded by an impure atmosphere. the east lothian colliers, of all miners throughout the kingdom, are certainly most subject to this disease; and those at pencaitland are so to a fearful extent. in the late inquiry for the parliamentary report, such has been manifestly brought out, and i am quite able to corroborate the conclusions at which the commissioners have arrived. it has been supposed by many that this carbonaceous affection was caused by inhalation of coal-dust. now, when it can be proved, that there is as much coal-dust at one coal-work as at another, the question comes to be, why should colliers, labouring at one coal-work, be subject to the disease; while those engaged at another, escape? for instance, there is as much coal-dust at penston and huntlaw, where there has never been black spit, as there is at pencaitland, preston-hall, and blindwells. i conclude, therefore, that this cannot be the cause, otherwise they should all be liable to the disease. again, those who labour as coal-bankers at the mouth of the shaft, are obliged to inhale much coal-dust in shovelling and arranging the coal received from the pit, and have the sputum tinged to a certain extent by it--which resumes its natural appearance when the collier leaves the labour producing it. they are not subject to the miners' cough, nor is there carbonaceous infiltration found in the lungs of such labourers after death. the females and boys, when, as formerly, both were allowed to labour, could not fail to inhale much of the coal-dust in which they were generally enveloped in their daily occupation; but no carbonaceous deposit has ever been found in the pulmonary tissue of either the one or the other. there are very interesting facts connected with the history of this disease, showing the length of time which the carbon can be retained, brought out by two cases on record, the one published as formerly mentioned by dr james gregory, in the _edinburgh med. and surg. journal_ for 1831, denominated, "spurious melanosis;" the other, a case published by dr william thomson, (_medico-chirurgical transactions of london_ for 1837), and which was reported to him by dr simpson, now professor of midwifery in edinburgh. dr gregory's case is that of john hogg, who had been in the army for more than twenty years, had seen much service as a soldier in america and the west indies, and had served in spain during the peninsular war. on his return to his native country, he was engaged for a short time before his death as a collier at dalkeith. i understand, upon inquiry, from those who were connected with hogg, that he wrought in early life as a miner at pencaitland coal-work, and was obliged, though a young man, to relinquish such employment on account of a chest affection, and exchange the pick for the musket. from the history of this case, and from the character of his occupation in early life, i apprehend that the carbonaceous deposit took place when he was first labouring as a miner at pencaitland; and that he carried the foreign body in his lungs, throughout his campaigns. the case reported to dr thomson by dr simpson is that of a george hogg, who lived at collinshiel, near bathgate. in early life, this man laboured at pencaitland coal-work, where the greater number of the cases now under consideration occurred; and it is stated as a certainty, that he contracted the black phthisis while occupied in that district; for i find from those who knew him at an early period, that his breathing was much affected while at pencaitland, and he was long supposed by his fellow-miners to have imbibed the disease,--indeed he removed from pencaitland on account of it. the two hoggs were relatives, and natives of east lothian. it is evident, from several of the cases, that it is no uncommon feature of this affection for the carbon to remain concealed in the pulmonary tissue for very many years; and as both the hoggs were miners at pencaitland, i have not the smallest doubt that it was then and there that the disease had its origin; for i have never known a collier who was a stone-miner who did not ultimately die of the carbonaceous infiltration. apart from colliers and coal-mines, as a proof that carbonaceous particles floating in the atmosphere are inhaled and lodged in the bronchial ramifications, i may state the following circumstance, which came under my own observation several years ago. after a gale of wind, which had continued for more than a week, off the coast of america, in the july of 1832, i was applied to for advice by several of the seamen, on account of a tickling cough, followed by a peculiarly dark blue expectoration, which i was told was almost general amongst the crew. i was certainly at a loss, and put to my shifts, to render a reason; but, upon investigating the matter further, i found that, during the gale, the chimney of the cook's apartment in the _'tween-decks_ was rendered inefficient, whereby the sleeping-berths were constantly filled with smoke. i found almost all the seamen, to the number of nearly a hundred, suffering considerably from cough, and expectorating an inky-coloured phlegm, which continued more or less for about a fortnight. i ordered soothing expectorants, and the dark sputa were profusely voided, and ultimately disappeared; but whether any of the carbon had made a permanent lodgment in the pulmonary tissue, is what i have never been able to ascertain. i am now convinced, in recalling this occurrence, that whatever be the situation, should carbon be floating in the air, it can be conveyed into the air-cells; and had these seamen been longer subjected to this foul atmosphere, a permanent lodgment of the carbon would undoubtedly have been the consequence, and the disease now under our consideration to a certainty produced. i further remember seeing, several years ago, a case of partially carbonized lungs in a person who had lived for a length of time in a smoky and confined room in glasgow. the patient died of dropsy, consequent, no doubt, on the pulmonary affection; and on examining the chest, the upper lobe of both lungs, and the bronchial glands contained black matter, similar in appearance to that found in the colliers. while engaged in committing these remarks to paper, i have been led in my investigations to compare the various kinds of labour carried on in coal-pits with the underground operations of many of the railways now in progress throughout the kingdom; and being convinced of the very injurious effects produced upon miners while prosecuting these operations in confined situations where gunpowder is used, i shall be much surprised if the same results do not follow the hazardous undertakings connected with railway tunnelling, where gunpowder is had recourse to, and in the course of years find in our public hospitals cases of carbonaceous lung arising from this cause.[19] it is no uncommon occurrence, in examining the pulmonary structure of those who have resided in large and smoky towns, to find both the substance of the lungs and bronchial glands containing black matter; and this is the case especially with persons who, in such situations, have passed the prime of life. but few, though not living in crowded towns, have not, at some period of their life, come in contact with smoke, and been obliged to breathe it, minutely combined with the air. it is not, therefore, to be supposed improbable, that a portion of the infinitely small particles, thus suspended in the atmosphere, should effect a settlement in the more minute air-cells, and in course of time, be conveyed to the interlobular cellular tissue by the process of absorption, and thence to the bronchial glands. there are several cases on record, from amongst iron-moulders,[20] where the pulmonary structure has been found heavily charged with carbonaceous matter, from the inhalation of the charcoal used in their processes, and where, during life, there was a free black expectoration.[21] there is, then, little doubt that the bronchial glands, from their appearance in miners, moulders, and others, are the recipients of a portion of impurities which have been carried into the pulmonary structure by inhalation, and also those left after the process of oxygenation of the blood; and when it is fully ascertained, from the character of the atmosphere in the coal mine, that deleterious matter in this form must be conveyed to the air-cells during respiration, there is little difficulty in coming to the conclusion, that the black fluid found to such an extent in these glands in the collier and moulder, is similar to, and a part of, that discovered infiltrated into the substance of the lungs. if we trace the black matter in the lymphatic vessels, (which has been done), from the pulmonary organs to the bronchial, mediastinal, and thoracic glands, and from thence to the thoracic duct, we cannot but admit, that it does find its way into the venous system, and thereby contaminates the vital current.[22] dr pearson of london, in his very valuable paper, published in the philosophical transactions of 1813, on the coaly matter in the bronchial glands, was convinced beyond a doubt, that it was of foreign origin, and possessed the properties of carbon conveyed into the lungs from without. he, at that period, was not in possession of such facts as have been recently elicited on the subject of deleterious inhalation; but the very interesting materials which he brought to bear on his argument, have, i think, most satisfactorily proved the assertion which he makes, that "the lymphatics of the lungs absorb a variety of substances, especially this coaly matter, which they convey to the bronchial glands, and thus render them of a black or dark-blue colour." "the texture and proportion of the tinging matter of the glands was," he says, "different in different subjects, whether the lungs to which they belonged were in a healthy or diseased condition. in persons, from about 18 to 20 years of age, some of the bronchial glands contained no tinging black matter at all, but were of a reddish colour; others were streaked or partially black." again, he says, "i think the charcoal in the pulmonary organs is introduced with the air in breathing. in the air it is suspended in invisible small particles, derived from the burning of coal, wood, and other inflammable materials in common life. it is admitted that the oxygen of atmospherical air passes through the pulmonary air-vesicles or cells into the system of blood-vessels, and it is not improbable, that through the same channel various matters contained in the air may be introduced. but it is highly reasonable to suppose, that the particles of charcoal should be retained in the minutest ramifications of the air-tubes, or even in the air-vesicles under various circumstances, to produce the coloured appearances on the surface, and in the substance of the lungs, as above described." "when i compare the black lines and black net-like figures, many of them pentagonal, on the surface of the lungs, with the plates of the lymphatic vessels by cruikshank, mascagni, and fyffe, i found an exact resemblance." dr pearson, after various chemical experiments upon the bronchial glands with caustic potash, muriatic and nitric acid, says, "i conceive i am entitled to declare the black matter obtained from the bronchial glands, and from the lungs, to be animal-charcoal in the uncombined state, _i.e._ not existing as a constituent ingredient of organized animal solids or fluids." dr graham of london, in his paper on this subject, recorded in the 42d vol. of the _edinburgh medical and surgical journal_, gives the following opinion, as the result of a series of investigations, with the view of determining the nature of the disease in question. he says, i have had several opportunities of substantiating the carbonaceous matter in a state of extraordinary accumulation in black lungs supplied by my medical friends. the black powder, as derived from the lungs, (after an analysis,) is unquestionably charcoal, and the gaseous products from heated air, result from a little water and nitric acid being retained persistently by the charcoal, notwithstanding the repeated washing, but which re-acting on the charcoal at a high temperature, coming off in a state of decomposition. in regard to another analysis of a lung, he says, "the carbonaceous matter of the lung cannot therefore be supposed to be coal, altered by the different chemical processes to which it has been submitted in separating it from the animal matter. the carbonaceous matter of this lung, appears rather to be lamp black." from the whole results, i am disposed to draw the following conclusions:-_1st_, the black matter found in the lungs is not a secretion, but comes from without. the _pigmentum nigrum_ of the ox i find to lose its colour entirely, and to leave only a quantity of white flocks, when rubbed in a mortar with chlorine water. sepia, which is a preparation of the dark-coloured liquor of the cuttle fish, was also bleached by chlorine, but the black matter of the lungs was not destroyed or bleached in the slightest degree by chlorine, it even survived unimpaired the destruction of the lungs by putrefaction in air. _2d_, this foreign matter probably varies in composition in different lungs, but in the cases actually examined, it seems to be little else than lamp black or soot. it does not appear, as far as i can ascertain, that any of the continental physiologists are familiar with the disease now under our consideration. several of them, both ancient and modern, discovered black matter in the pulmonary tissues, but not connected with nor exhibiting the black phthisis. it is therefore unnecessary to refer to them in general. the following foreign authors entertain various opinions in regard to the dark appearances in the pulmonary tissue:-bichat supposes the black matter in the lungs "to be owing to small bronchial glands extending along the surface of the pleura." breschet believes that it is formed by the blood exhaled into the cellular tissue, stating that its chemical composition leads him to that conclusion. trousseau says that it is produced by a misdirection of the natural pigments of the body, resulting from age, climate, or disease. andral says, that the black appearances are the result of secretion, and that it is more manifest as the individual advances in life. heasinger's opinion is, that it is analogous to pigment, and therefore he agrees with trousseau. lænnec was doubtful as to the real origin of black pulmonary matter. he makes a distinction between melanotic and pulmonary matter. he found that the melanotic matter was composed almost entirely of albumen, while the black pulmonary matter found in the bronchial glands contains a great quantity of carbon and hydrogen, and also that these colouring matters have other distinguishing characters. the melanotic matter is easily effaced by washing, while the other is removed with difficulty. lænnec further says, that he suspected that this pulmonary matter might arise, at least in part, from the smoke of lamps, and other combustible bodies which are used for heat and light; for some old men are to be met with whose lungs contain very little black matter, and whose bronchial glands are but partially tinged with this colour; and it has struck him that he observed this amongst villagers who had never been accustomed to watch.[23] mons. guillot, physician to the hospital for the aged at paris, has undertaken a series of researches in regard to the black matter found in the lungs of old men of very considerable age. these investigations are published in the january, february, and march numbers of the _archives générales de médecine_.[24] it is his belief that death in such cases is owing, in all appearance, more or less to a suppression of the circulation of air and blood by the black substance. his impression is, "that the carbon is not procured from without, but naturally deposited, as life advances, in the substance of the respiratory organs; and that this deposit of carbon causes death, by rendering the lungs irrespirable, while, at the same time, it has much influence in modifying the progress of _tubercular_ disease; so that, if the tubercular affection was not cured, its progress was so far checked, that life has been very long preserved." the black matter envelopes completely both the pulmonary tubercles which have undergone a transformation, and the caverns which no longer contain tuberculous matter. he, while regarding these as the results of black matter in the lungs, throws no light on the cause of the deposit of the particles of carbon within the lungs. dr william craig of glasgow, in a letter to mr graham of london, published in the 42d vol. of the _medical and surgical journal of edinburgh_, states most interesting facts connected with this subject, particularly in regard to black matter found in the pulmonary structure of old people, which deserve considerable attention. he says--"i found that a black discoloration of the lungs was by no means a rare occurrence amongst those old people; and that it was impossible in many instances to decide, whether the black colour was owing to an increase of what is called the healthy black matter,--to a morbid secretion, or to a foreign substance being imbedded with the atmospheric air. after examining a considerable number of lungs, and finding that the division of the black matter into three kinds was not founded upon observation, and that the descriptions of them given by the best authorities were insufficient to enable us to distinguish them from one another, i begin to think, that in every instance in which black matter is found in the lungs, it ought to be considered morbid. if we examine the lungs at different stages of life, we find as a general rule that the quantity of black matter increases with age. in young children we find no traces of it, the lungs being of a reddish colour. at the age of ten years the black matter makes its appearance in the outer surface of the lungs, and in the interlobular spaces. at the age of thirty or forty, the lung presents a greyish or mottled appearance, and the bronchial glands contain more or less black matter. between the age of seventy and a hundred, the lungs are generally infiltrated with fluid black matter, which can be expressed from the cut surfaces, and stain the hands black." "there are many circumstances which favour the accumulation of this black matter in the lungs; for instance, long-continued living in a smoky atmosphere, like that of this city, the inhalation of coal-dust, as in the case of colliers, or of charcoal-powder, as in the case of iron-founders. there can be no doubt that we inhale foreign substances along with the atmospheric air. "we find the mucus which has remained in the nostrils for some time to be of a dark colour, and if we examine it with a microscope, we find, that this is owing to the presence of small particles of dust or other foreign substances, which the air may have accidentally contained. the mucus first coughed up from the lungs in the morning, is of a dark colour from the same cause, and the facts now maintained prove, that foreign substances suspended in minute particles in the atmosphere, may be inhaled into the lungs. i believe in all the extreme cases which have occurred in colliers and moulders, that there must have existed some previous disease of the lungs which prevented the foreign matter from being thrown off." "according to the views which we have taken of the subject, there are only two ways by which black matters may be deposited in the lungs; first, by a morbid secretion; second, by a foreign substance inhaled with the atmosphere. the former is a rare disease, while the latter is very common. i am inclined to think that the true melanosis generally occurs in the form of rounded tumours, which, when cut in two, present a uniform black colour without any trace of air-cells, while in the spurious melanosis the deposition is general, and black matter flows freely out when the cut surfaces are pressed. at first the lung is crepitous, and swims in water; but as the black matter increases, it becomes solid, and, as in the case of colliers who die of this disease, resembles a piece of wet peat in point of consistence. it is only in the cases of colliers, moulders, or others who inhale great quantities of black matter, that the lungs are rendered perfectly solid." there is an exceedingly interesting and valuable paper, written by dr brockmann of clausthal, upon the pulmonary diseases of a certain class of german miners,--supposed to be in the hartz mountains,--in _neumeister's repertorium_ for december 1844, an abridged translation of which is to be found in the september number of the _monthly journal of medical science_. it is very evident that the disease there considered is produced by carbonaceous inhalation, and resembles in all its features the black phthisis so general amongst the colliers in haddingtonshire. the morbid appearances described by dr brockmann are very similar to the first and second division of that disease, presenting a very general carbonaceous infiltration of the pulmonary tissues; but in none of the stages are there to be found the extensive excavations discovered in the lungs of the coal-miner. dr brockmann makes three divisions of the morbid appearances, "the essential (wesentliche), accidental (zufällige), and secondary. the first shows an entirely black (pechschwärze) colour of the lungs through its whole substance, enclosing not only the air, blood, and lymph vessels, but also the connecting cellular tissue, the nervous substance, pleuræ pulmonalis, and bronchial glands." in such a state, it is usual for the lung to remain perfectly normal, and to exhibit the greatest varieties. the accidental (zufällige) is evidently the disease in a more advanced form, corresponding in a great measure with the second stage of the morbid action, found in the pulmonary organ of the collier. it is to be regretted that no accurate description is given either of the character of the mine, or the nature of the employment in which the miners are engaged, whether they be coal, silver, or lead mines, and if they are in the habit of burning coarse lint-seed oil. there is a very striking similarity between what dr brockmann calls the secondary anatomical changes, and many of those exhibited in the collier; first, membranes; second, collections of fluid into the pleuræ and pericardium; third, the softened heart, and very general emaciation; fourth, the extensive venous congestion, with thick black blood. the liver is described by dr brockmann as being small:--in the collier it is usually puffy, and much congested. the symptoms do almost in all points accord with those presented in the collier, as will appear from the following quotation, from the paper. "in the first stage, there is no local, functional, or general feature by which we can ascertain that the disease has commenced; probability is all we can reach. in the second stage, the disease is more obvious. and, first, there is a change in the expression of countenance; to a fine blooming appearance, which perhaps the patient previously had, there has succeeded a dark yellowish cast,--a change which gradually spreads over the whole body. for some time the patient may have remarked a gradual loss of strength, and now he complains of want of appetite and disordered digestion, and more particularly of shooting pains in the back and muscles of the chest. cough likewise supervenes, which may either be quite dry, or at most accompanied with a little pure mucus. there is also a greater or less degree of oppression, accompanied with palpitation of heart, not only after a severe fit of coughing, but after every exertion of the lungs. as yet no local deviation from the normal condition is seen on examination of the chest by percussion or auscultation." "the disease meanwhile passes into the third stage. the features of the patient now become more and more changed and deteriorated, and betray a deep melancholy. the colour of the face, which had been hitherto of an earthly hue, becomes blackish, as also the cornea, whereby the eye loses its lustre. the appearance of the patient becomes still more frightful from the great loss of flesh, and the dark skin hanging loose on his bones. the fat not only seems to have disappeared, but the muscular substance also--the whole frame being shrivelled. the patient complains of increasing weakness, diminished appetite, flying pains often concentrated at the pit of the stomach; and coughs much. the expectoration is for the most part difficult, and consists of masses of mucus, either greyish, or tending to a black colour. a black streak is frequently observed running through the whitish mucus; one half of it may be white, the other black, or occasional black points may be observed throughout the mass, and sometimes, though rarely, blood. dyspnoea is usually connected with the cough. it now begins to tell upon the patient, and is so characteristic, that the disease has been named asthma metallicum. the disturbance of the digestive organs increases the disease,--the appetite is entirely lost,--the tongue is covered with a white fur--there is an oppression at the stomach after a full meal--frequent eructations, and a tendency to constipation. the distress of the patient becomes increased in consequence of the shooting pains in the muscular system." "in the fourth and last stage, all the external appearances indicate the near approach of dissolution,--the face and members become bloated, and the feet greatly swollen." "the dyspnoea meanwhile, from effusion into the chest and pericardium, becomes so severe, that the patient cannot maintain the horizontal position, the expectoration becomes copious, consisting of a black inky (dintenschwarze), or ash-coloured fluid, sometimes of mere masses of mucus streaked with black." "the disease is never accompanied with colliquative sweats or diarrhoea." i am sorry to find that there is no allusion whatever to the state of the pulse. dr brockmann, in his remarks on the essential nature of this pulmonary disease of miners, brought under his notice, seems to entertain the impression that along with the inhaled carbon, resulting from the combustion of gunpowder, there is also an organic pigment-deposit present in the pulmonary tissue, which he supposes must have been formed in the lungs. i have long entertained the belief, which i have stated in another part of this essay, that if the carbon is once conveyed into, and established in the parenchyma of the lungs, that organ commences the formation of carbon; thus increasing the amount originally deposited. dr brockmann sets forth, as grounds for this view, that "if the parenchyma of the lungs were filled with carbonaceous dust, their specific gravity ought to be increased; but this is not the case. a completely melanosed lung swims in water, both as a whole and when cut into parts." it is very evident from these remarks, that the author has not seen the disease as it is exhibited in the third division of morbid action in the collier, otherwise he would have both observed the lungs considerably augmented in weight, and also so densely impacted from the accumulation of carbon, as wholly to sink in water. see for instance case no. 2, where the lungs weighed about six pounds, and parts of the cellular tissue were so indurated, as to be cut with difficulty. in this case, the patient did not expectorate. dr brockmann, as he advances, puts a question here, which more fully shows that the disease under his consideration was of a mild character compared with that under our notice. "if," says he, "pulmonary melanosis arise entirely from inhalation of carbonaceous dust, why is it not observed in other workmen, who are as much, and even more, exposed to its influence, as for instance, smelters, or moulders, and colliers?" he says, further, "were the carbon inhaled in quantity sufficient to explain the black colour of the lungs, it ought also, from its mechanical irritation, to produce inflammation in the delicate mucous membrane of the organ, but there are no symptoms of this during life, nor any traces of it after death." an answer to these remarks will be most satisfactorily given by a reference to the published cases, where the disease is principally found amongst colliers and moulders, and where the pulmonary organs, particularly in the former, are found to undergo most fearful disorganization from the presence of carbon. it is very remarkable, that the author of these exceedingly interesting observations should never have found excavations of the parenchyma, when it is so general as the result of the same disease in this country, particularly in the locality to which i refer. not knowing the character of the mine, it is impossible to judge; but i am disposed to conclude that there cannot be the same quantity of carbon floating in the atmosphere breathed by the german miner,--the disease resembles very much that milder form found in the iron moulder. with regard to the carbonaceous state of the blood, i am sorry that i have not yet completed my investigations on that subject. it is still my belief that the carbon being once inhaled, there is an affinity found for that in the circulating fluid, and from its not being consumed, owing to a deficiency of oxygen, there is a progressive increase going on. i am very much gratified to find that dr brockmann entertains a somewhat similar opinion in respect to the state of the blood. the effects of such a morbid structure upon the collier population in general is very marked. previous to the late legislative act, the tender youth of both sexes were at an early age consigned to the coal pit, and obliged to labour beyond their feeble strength, in circumstances ill adapted to their years. such early bodily exhaustion soon produced in them a pallid countenance, soft and relaxed muscular fibre, and predisposed much to disease as they advanced in life. the miner on this account was generally from his youth, thin; in fact, you never see a fat and healthy-looking collier, and, according to the advance of pulmonary disease, with them, so is the progress of emaciation. such a state of body may well be looked for in miners, labouring as they do, from ten to twelve hours in the twenty-four under ground, breathing a heated and impure atmosphere, which with difficulty sustains life, and which is demonstrably calculated, from its deleterious qualities, to induce serious disease. the effects manifest in the parent descend, and visible in the youngest children; they are squalid and wretched-looking,--and how can such offspring be otherwise? they are exceedingly subject to all children's diseases, and peculiarly predisposed to pulmonary irritation of one kind or other. with regard to medical treatment, little can be done after the disease has passed its first stage. early removal from the occupation, and proper attention to nutrition, alone seem to hold out the hope of prolonging the life of the patient; but if there be carbon lodged in the pulmonary tissues, there is a certainty of its sooner or later proving fatal. attention to the state of the digestive organs, and using every means to remove the dyspeptic symptoms, which are prominently present throughout the various stages of this disease, are indispensably requisite; and, as to nutrition, the nature of the diet should be as generous as possible. anodynes and expectorants are the only remedies which seem at all efficacious in allaying irritation. with a view to remove urgent symptoms, venesection has repeatedly been had recourse to, but in almost all instances i would say, with decidedly bad effects. blood-letting does harm, producing general debility and rapid sinking.[25] with regard to the prevention of this disease, ventilation, as has been stated, is very much neglected in the pits now under consideration, where the various cases have occurred; and to that neglect i ascribe the prevalence of the malady. in those pits referred to, the workable apartments are so confined, and become after a time so destitute of oxygen, as, along with the smoke from lamps and gunpowder, to render the air unfit for healthy respiration. the only effectual remedy is a free admission of pure air, so applied as to remove the confined smoke. this remark both applies to coal and stone-mining. the introduction of some other mode of lighting such pits than by oil is required. i know several coal-pits where there is no carbonaceous disease, nor was it ever known; and on examination i find that there is and ever has been in them a free circulation of air. for example, the penston coal-work, which joins pencaitland, has ever been free from this disease; but many of the penston colliers, on coming to work at pencaitland, have been seized with, and died shortly after, of the black spit: for instance, g. case no. 5, and d. case no. 8, are such. how this is to be accomplished, is for the scientific man to say. with all due deference, i may be allowed to suggest various modes which might be adopted to free the underground atmosphere of the noxious ingredients. could fresh air not be forced down by the power of the steam-engine, which is at every coal-pit? could extensive fanners not be erected and propelled by the same machinery?[26] i am much surprised that no attempt has been made to light these pits with portable gas in some way or other. as far as i can understand, such an application of it would not be difficult. a small gasometer could be erected, and the necessary apparatus procured at little expense, and by such means, i would suppose, it could be carried to any part of the mines, which are not extensive. many proprietors may grudge the expense involved in such improvements, and thus prove a barrier to these necessary alterations; but i would ask any candid and generous mind, what is expense when the object in view is the removal of a disease to which many human beings fall a sacrifice?[27] it must appear to every one that these collier diseases are crying evils, the preventive of which is based, as will be seen, on thorough ventilation; and in order to protect the miner, there should be a vigilant attention paid to the economy of underground works. no one need be surprised at the result of such a noxious atmosphere; and it becomes a duty with the government to protect these poor people by laws, and to adopt those measures which are best calculated to preserve their health; and should there arise difficulties of an insurmountable character in the ventilation of these pits, why continue the mining operation in such situations at such a sacrifice of human life?[28] * * * * * in the course of my investigations in regard to pulmonary carbonaceous infiltration, i was led to consider the circumstances of those engaged in other occupations than coal-mining. any one who has carefully examined the structure of the human bronchial glands, at different epochs of life, must have been struck with their appearance in those who, from their vocation, are compelled to breathe a sooty atmosphere, or who have lived in ill ventilated dwellings. i am further convinced, from the results of my recent investigations, that the bronchial glands in such persons invariably contain carbonaceous matter which has been inhaled at some period of life. having long entertained the belief that the lungs of chimney sweeps, for example, would, in all probability, be found to contain carbon, within the last few months two cases, of an exceedingly interesting character, connected with the present inquiry, have presented themselves,--the one of pulmonary disease, evidently resulting from the bronchial and lymphatic glands being impacted with inhaled carbon derived from soot,--the other a case of melanosis occurring in a young person. though the two diseases differ materially, they have often been confounded with each other and assigned to the same cause. my object in here reporting a case of stratiform melanosis, in connection with a disease having an external origin, is to afford an illustration of the fact, that all black deposits found in the system are not carbon. there exists a marked chemical distinction between the melanotic and the carbonaceous matter; and the anatomical situation of the two is also different. case.--a chimney sweep, aged 50, of the name of campbell, residing at stockbridge. the short history of his case i procured from his friends, as i did not see him during his illness. he had been a soldier in early life, and had seen much foreign service. after he relinquished the army, he became a chimney sweep, in which capacity he was constantly engaged for nearly twenty years. he had had, for a considerable time, a troublesome cough with tough expectoration. he experienced a difficulty of breathing in making any exertion, and he had considerable oedema of the limbs. from these symptoms he believed that he was subject to _asthma_. he had only been confined to bed for two days previous to his death. _post-mortem appearances._--the body exhibited extensive anasarca; the thorax was well arched; the cartilages of the ribs were ossified. on removing the anterior part of the chest, the pleuræ were found to adhere strongly, and appeared rough and puckered from extensive exudation of a brown colour, which extended very generally over the serous membranes. both cavities contained nearly three gallons of light brown fluid. the pericardium was considerably distended with a straw-coloured fluid, and several flakes of lymph floated throughout the effusion. both auricles of the heart were enlarged, and distended with exceedingly dark blood. the walls of both ventricles were much thickened. the valvular structure of the auricles was congested and granular. the lungs were removed from the chest with difficulty, owing to the very general pleuritic adhesions. both exhibited extensive emphysema. in dividing the lungs, and tracing the bronchial ramifications, each lobe was found to contain clusters of enlarged and indurated bronchial glands, impacted with thick black matter; and prosecuting the investigations, the minute lymphatic glands were observed clustered in a similar manner, and containing black fluid. in the substance of the upper lobe of both lungs, the bronchial glands were of a bright black colour; they were particularly large, and so numerous as to press considerably upon and obstruct several of the bronchial tubes. in fact the upper lobe of both lungs exhibited the plum-pudding structure. at the bifurcation and back part of the trachea, the bronchial glands were numerous, and of a deep black colour. a considerable mass of the glandular structure was removed for chemical and microscopic examination. the second case was that of a boy aged six years, who was under treatment for an affection of the heart and kidneys, and who died apparently from disease of these organs. he was, during his whole life, of a relaxed and weakly constitution, exceedingly sallow in the complexion, with a very deep blue tint of the sclerotic coat of the eye. in the course of the post-mortem examination, there was discovered, in the lower and lateral part of the right pleura, a cyst containing about an ounce of semi-fluid melanotic matter; and also the morbid secretion presented the stratified appearance described by dr carswell in his article upon melanosis, extending over the inferior half of the costal pleura and the corresponding part of the diaphragm. it formed a distinct layer on the surface of the serous membrane, resembling ink or blacking, and could with difficulty be removed. the black deposit resembled much in appearance the foreign matter found in the pulmonary organs of the coal-miner, and therefore was submitted, as well as the bronchial glands in the other case, to chemical analysis, with the view of ascertaining if there existed any analogy in the component parts of each. dr douglas maclagan submitted both these substances to the action of concentrated nitric acid, and the results were, that the glandular structure of the chimney sweep contained a very large proportion of carbon, while of the contents of the melanotic cyst, the same process did not leave a vestige of colouring matter,--evidently proving the distinction which exists between those two dark deposits, and making it sufficiently obvious, that melanotic matter is composed of the constituent elements of the blood, and has its origin within the body. there cannot remain a doubt as to the nature of the chimney sweeper's case; for, from the knowledge which we have of his occupation, and from the chemical properties manifest after investigation, i think i am entitled to declare the black matter obtained from the bronchial glands to be carbon inhaled with the air during his labour, and not existing as a constituent ingredient of organized solids or fluids. the microscopic examination showed the carbon most distinctly in a molecular form. it is my intention to return to this subject at a future time. northumberland street, edinburgh, january 1846. * * * * * footnotes: [1] vide an admirable series of papers on this subject in the volume of this journal for 1843, by dr calvert holland. [2] about ten miles east from edinburgh. [3] generated from the decay of vegetable and other substances in the _formerly wrought_ pits, which communicate with those at present in use. [4] it is proved, from the difference in the chemical character possessed by the melanotic matter, as compared with the matter found in the lungs of miners. [5] it will be observed, that, though the small blood vessels are destroyed, no hemorrhage takes place, owing to the formation of a carbonaceous plug. [6] the air of the coal-pit is so charged with carbon as to prevent the collier from distinguishing his neighbour when at work. [7] note from the evidence of a collier examined before the government commissioners in 1842, no. 147 of report. "colliers in this part of the country are subject to many oppressions; first, black spit, which attacks the men as soon as they get the length of 30 years of age;" second, note 150, "the want of proper ventilation in the pit is the chief cause, and no part requires more looking after than east lothian," the men die off like rotten sheep. note, 153, the witness, 32 years old, says, "i am unable to labour much now, as i am fashed with bad breathing--the air below is very bad, and till lately no ventilation existed." [8] the black sputum retains its colour after being submitted for some days to the action of nitric acid. [9] this is the only case in which i at any time observed colliquative sweats as a symptom of this disease. [10] to convey an impression of the nature of the labour in which the man was engaged i shall simply extract a few remarks from the evidence of the miners at this coal-work, taken by mr franks for the government's commissioners, note 105. "at all times the air is foul, and the lamps never burn bright. the seam of coal is 24 inches, and the road only three feet high." note 108--"experienced colliers do not like the work, and many are touched in the breath." and in such a situation man is doomed to labour! note 114--"most of the men here are _fashed_ with _that trouble_; foster, miller, blyth, and aitken are all clean gone in the breath together. colliers here drop down very soon." [11] it is evident in this disease that the bronchial ramifications are destroyed, while the arteries, with the exception of the minute twigs, are preserved. [12] one of the lungs (the left one) now described, i sent to dr john thomson, late professor of pathology, and will probably be found in his collection, which i understand is in the college of surgeons. [13] after a free expectoration of black matter, there was an evident mitigation of all the pectoral symptoms, and as the carbon again accumulated in the lungs, the sufferings of the patient were very considerably increased. [14] this sputum was subjected to the action of nitric acid, which produced no effect upon its colour. [15] when pulmonary disorganization has proceeded far, from the presence of carbon, there is a languor in the vital action from defective oxygenation of the blood, which produces a gradual reduction in the temperature of the body, requiring double clothing, and even that addition is, with the aid of stimulants, not sufficient to keep the patient warm. [16] this lung is in the possession of sir james clark, of london. [17] the above substances were submitted separately to the action of nitric acid and caustic potash, and the result was that a large proportion of carbon was precipitated. [18] since writing the above the patient has died; and i regret that, owing to neglect in communicating with me, i have been prevented examining the morbid appearances. [19] several of the pencaitland colliers are at present engaged in the tunnelling operations near to edinburgh, connected with the north british railway. [20] dr hamilton's of falkirk paper in the edin. med. and surgical journal, vol. xlii. [21] i have very lately, through the kindness of mr girdwood, surgeon at falkirk, had an opportunity of examining two or three iron-moulders in that district. both from the nature of the employment in those iron works, and the character which the pulmonary affection exhibits, the fact of inhalation is fully established. the moulder is at a certain stage of his labour enveloped in a cloud of finely-ground charcoal, a portion of which cannot fail to find its way to the lungs in breathing. he is subject to tickling cough, and as the disease advances, the respiratory sounds, which indicate considerable bronchial irritation, present themselves, and ultimately become dull, and in some parts obscure. of the several cases which i saw with mr girdwood, one, who has not been labouring for some years as a moulder, occasionally expectorated black matter, and in the other two, there was general dullness of both lungs; and, i doubt not, impaction. [22] it has not been in my power hitherto to procure so satisfactory a chemical analysis of the blood as i would wish, but through the kind assistance of dr douglas maclagan, who has undertaken to conduct the process, i expect very soon to be able to lay it before the profession. [23] i found little or no black matter in the lungs of farm servants, who are much in the open air. [24] _vide_ monthly journal for 1845, p. 702. [25] at any time when these colliers required venesection, particularly towards the last stage of the disease, the blood appeared peculiarly dark and treacle-like. [26] could oxygen not be prepared and forced down? [27] i am happy to find that the attention of the noble proprietor of the newbattle coal works is now directed to this subject. [28] i cannot pass from this subject without an observation on the beneficial results which have been the consequence of lord ashley's valuable colliery act. the female labourers, and particularly the unmarried, have improved not only in their appearance, but also in general physical development, since they have abandoned the unhealthy labour of the coal-mine. they are no longer the squalid, filthy, and ill-favoured race they formerly were. there is now exhibited on the face of the collier girl the bloom of health and cheerfulness; and when we descend to their domestic economy, there is observed a comfort in the management of their households, which formerly did not exist. their children are now particularly cared for, both in health and when suffering from disease; and we must regard this early watching as an important step to the removal of that predisposition to pulmonary irritation, so general in the collier community. adenoids and diseased tonsils their effect on general intelligence by margaret cobb rogers, ph.d. archives of psychology edited by r. s. woodworth no. 50 columbia university contributions to philosophy and psychology new york april, 1922 agents: g. e. stechert & co.: london: (2 star yard carey st., w. c.); paris (16, rue de conde) contents introduction purpose of the study. 5 chapter i. 7 previous literature concerning the relation of nose and throat defects to intelligence. chapter ii. 24 method and procedure. 1. a statistical study. 2. a study of improvement after treatment. selection of cases. the tests. chapter iii. 29 discussion of the results. 1. the statistical study. 2. the study of improvement after operation. chapter iv. 53 measurement of improvement after a second interval of six months. chapter v. 68 summary. conclusions. introduction--purpose during the last decade or two there has been a growing interest among physicians in defects of the nose and throat. this interest has centered in part upon those two afflictions of childhood--adenoids and diseased tonsils,--or even tonsils that are merely enlarged. there is no doubt of the physical handicap borne by a child who is possessed of them. as a seat of inflammation, a source of infection, a hindrance to proper breathing,--in a multitude of ways they have seemed to deserve the verdict,--"have them out." many physicians, to be sure, have cautioned against the wholesale removal of tonsils, saying that tonsils which are large in early childhood very commonly are absorbed at an early age. but it is not my purpose to discuss the question of the efficacy of removing adenoids and tonsils. the aim of this study is, rather, to determine experimentally whether or not there exists any causal relation between defect in this respect and lowering of intelligence level. one hears statements made both pro and con by physicians and laymen but there has been little experimental proof. it would seem to be rather useful for a physician to know in advance with how much probability of correctness he is speaking, when he advises a mother that the removal of adenoids and tonsils from the throat of her backward child will make him "bright." the question in the present case, however, is broader than that of relation between these afflictions and mental defect. we are inquiring not merely whether adenoids and tonsils are causes of sub normality or dullness, but also whether they tend to lower the intelligence quotient in general however high it may be. would the mentally normal child with adenoids and tonsils have been superior without them, and would the superior child have been still more superior? what is the relation between adenoids and tonsils, and intelligence? the method employed in the present experiment would seem to give it value from the point of view of the clinical psychologist. with the present emphasis upon exactitude in mental testing, investigators have become interested in problem of the constancy of the i.q. adenoids and abnormal tonsils have been suggested as possible factors affecting this constancy. the results of the experiment should throw some light on the question. it should be understood that this study is concerned with general intelligence, and not with the child's efficiency as a member of society. the latter question is much broader than the one we are investigating. it includes not only intelligence, but physical state, emotional make-up, volition: in short, the personality as a whole. success in school work for example, depends upon all of these factors. for that reason, the results to be reported here, cannot be interpreted as applying to this broader conception. we cannot say at the end whether or not the physical defects under consideration affect the child's success as a member of society. we hope to be able, however, to determine their effect upon one element of that success, namely intelligence. in presenting the results of this experiment, the writer is especially indebted to professor r. s. woodworth, under whose auspices the investigation was carried out, for his interest and advice; and to dr. leta s. hollingworth for the suggestion of the problem, practical aid in obtaining subjects, and constant inspiration. she is indebted to the school of education, teachers' college, for the provision of operative treatment for the subjects; to mr. mark and his officers at public school 64; and to superintendent o'brien of the manhattan eye, ear and throat hospital. it must be said that by their hearty and generous cooperation they have contributed in a large measure to whatever value this study may possess. adenoids and diseased tonsils: their effect upon general intelligence chapter i. previous literature concerning the relation of nose and throat defects to intelligence there are very few experimental studies of the relation between intelligence and the two defects considered here. there are a few statistical studies, and among earlier writers especially many statements of opinion on the matter. characteristic of the latter is the following extract from an article in the boston medical and surgical journal, march, 1886.[1] [1]: f. hooper, m. d., quoting from a paper by b. frankel. "... it is a fact that their intelligence may become weakened and their characters changed. they do not progress in their studies at school, are generally at the bottom of the class and remain in it longer than the prescribed time.... that the impairment of intellect and want of energy manifested by these children is real, and not merely in the expression of countenance, is made evident by watching these same children after the growths have been removed. to the gratification and astonishment of the parents and teachers, the children hitherto sluggish and dull of comprehension, now make rapid progress, and their comrades soon cease to make a laughing stock of them." the following quotation from an article by irving townsend, m. d., is in the same vein:[2] [2]: adenoid growths of the naso-pharynx. read before the homeopathic medical society of new york, february, 1895. "aprosexia is the rather imposing term applied to the imperfect or arrested mental development attributed to this condition. this is denied by some authors, who claim that the dullness of comprehension and inattention are only apparent, and due only to defective hearing. a strong evidence of its reality lies in the fact that these children show most marvelous intellectual development after the removal of the growth, even in cases where deafness is not markedly improved." a most enthusiastic denouncer of adenoids and abnormal tonsils is h. addington bruce. concerning their direful effects upon the intelligence, and the magical results of their removal, he is continually reiterating:[3] [3]: h. addington bruce, psychology and parenthood, 1916. "often a surprising development of both mental and physical power follows the removal of adenoids. in one case reported by professor swift, a girl of fourteen grew three inches within six months after an operation for adenoids, and at the same time showed an improvement in her school work that contrasted strikingly with the dullness that preceded it. another, three years younger, grew six inches in about five months, and from being a sad idler was transformed into an unexpectedly attractive and bright pupil. a boy of twelve, backward both mentally and physically, likewise lost his dullness and laziness within an astonishingly short time after the impediment had been removed." and again: "the boy or girl suffering from adenoids[4] is usually a mouth-breather because of the difficulty experienced in breathing through the nose. but mouth-breathing means difficult breathing, and this in turn means deficient oxidation of the tissues, with a resultant lowering of vital activities generally and of the activity of the brain in particular. accordingly, the psychologist of today insists that every adenoid-afflicted child should be given prompt medical attention, with a view to correcting the vicious mouth-breathing habit, and thus aiding the child to gain a fair start in the development of mental and physical health." [4]: h. addington bruce in the century magazine, 1916--the mind of the child. the following extracts are quoted from burgerstein's "handbuch der schulhygiene": "bresgen und heymann machen endlich darauf aufmerksam, dass die ursache der kephalalgie haufig in der behinderung der nasenatmung zu suchen ist, als folgerscheinung von verengerung der nase bei ingen baue des knochengerustes, knochenkaries und geschwulsten, schwelungen der scheimhaute, akuten schnupfen, verstofungen der highmorshöhle, vergrosserung der mandeln u. s. w."... "viele kinder erscheinen schwachbegabt, ohne os zu sein, da bei denselben entweder nach behebung von ohrenkrankheiten, nach herstellung der freien _atmung oder gebrauch einer entsprechenden brille die scheinbare geistesschwache schwindet_."[5] [5]: the italics are mine. quotations like these, and equally unsupported by experimental evidence, might be multiplied indefinitely, especially if we look into the literature of a dozen years ago. since they can have little authoritative value, i shall limit myself to two more specimens, one taken from the psychological clinic, 1916.[6] [6]: psych. clinic, 1916, 10, 45-48. anna johnson. the teacher in the retarded school. "but when these physical defects (poor eyesight, defective hearing, adenoids, bad tonsils, etc.) are corrected so that the mind can function without any outcry from the physical body, these children recuperate mentally and often make greater progress than the so-called normal children in the regular grades." the second is a quotation from jelliffe and white, "diseases of the nervous system." lee and ferbiger, 1917, p. 903. "an important group (of mental defects) is due to adenoid vegetations in the posterior pharynx. under such conditions of ill health, development is impaired and does not proceed at a normal rate. with ... infected tonsils, which produce a constant toxemia, the child cannot be expected to proceed in his development with normal rapidity." in the medical and psychological literature of the last few years, along with the growth of general discussion into the various phases of the operation itself, we find a general disinclination to take on faith the magic effect of adenectomy and tonsillectomy. this growth of critical spirit has shown itself in statistical investigations, and in studies of pedagogical and mental improvement after operation. the statistical studies of physical defects in the schools reveal almost universally a positive relationship between school retardation and possession of adenoids and diseased tonsils. one of these was conducted by ayres for the backward children investigation of the russell sage foundation in new york city.[7] the investigators examined the school records of 20,000 children from fifteen schools in manhattan. eight thousand of these had been examined by school physicians. the records of the physical examinations showed that 80 per cent of the children who were normal for their grade had physical defects while only about 75 per cent of the retarded children were physically defective. [7]: psych. clinic, 1909, 3, 71-77. the effect of physical defect on school progress. this astonishing result was found upon re tabulation of the data by ages, to be due to the fact that for each defect there is a gradual falling off in frequency from the age of six up to fifteen--eye-defect, only, excepted. since the retarded children in each grade will be the older children in that grade, and since older children have fewer defects, the retarded children will show a smaller proportion of defect. to overcome this difficulty, ayres used an age basis instead of a grade basis in interpreting his results. records of all the children at the ages of 10, 12, 13, and 14 were re tabulated, a group of 3304 children, and rated as dull, normal or bright according to the grade in which they were found. the results were worked out in percentages of a group, and are shown in the following tables: dull normal bright number of children examined 407 2588 309 defects per child 1·65 1·30 1·07 enlarged glands 20 13 6 defective vision 24 25 29 defective breathing 15 11 9 defective teeth 42 40 34 _hypertrophied tonsils_ _26_ _19_ _12_ _adenoids_ _15_ _10_ _6_ other defects 21 11 11 defective 75 73 68 not defective 25 27 32 average number of grades completed by pupils having no physical defects, compared with the number completed by those suffering from different defects: 3304 children, 10-14 years, grades 1-8 average grades completed % lost children having no physical defects 4·94 children having enlarged glands 4·20 14·9 children having defective vision 4·94 0 children having defective breathing 4·58 7·2 children having defective teeth 4·65 5·9 _children having hypertrophied tonsils_ _4·50_ _8·9_ _children having adenoids_ _4·24_ _14·1_ children having other defects 4·52 8·5 cornell reports several investigations in the psychological clinic, january and may, 1908. three of these, in which children were rated on the basis of grades received in school work, are here combined to show the grades of normal children, "average" children, generally defective children, those possessing adenoids and tonsils, and the deaf. general adenoids no. of cases normal average defective and tonsils adenoids deaf allison 219 9th st. 64 84 21 8 claghorn 179 252 13 grade in language 9th st. 72·9 70·5 63·3 60 claghorn 74·4 72·7 71·4 grade in arith. 9th st. 75·5 74 70 66·7 claghorn 72 70 65·1 grade in spelling 9th st. 75·4 72·8 64·8 65 grade in geography claghorn 76·6 76·5 76·2 average of grades allison 75 74 72·6 72 67 9th st. 74·6 72·4 66 63·9 claghorn 74·3 73·1 0·8 an additional investigation of four classes in the same grammar grade of the claghorn school gives the following results: class 1 class 15 class 9 class 11 bright children dull dullest number of children 50 39 32 29 normal 36 32 20 13 defective 14 7 12 16 percentage of normal 72 82 62·5 44·8 in the same article, dr. cornell gives the results of another study of philadelphia schools, made in 1906. the study comprised a comparison of children exempt from examinations on account of high standing, with those not exempt. the results follow: exempt children non-exempt children normal defective normal defective 9th st. primary 56 28 39 38 rutledge school 87 35 75 34 allison school 128 65 81 49 camac school 183 71 103 75 claghorn school 193 61 127 66 -- -- -- -- 647 260 425 262 percentage defective 28·8 38·1 when the four classes of bright and dull children were examined again, and the different sorts of defects compared for the groups, enlarged tonsils, adenoids, deafness, and nasal catarrh, were found to occur much more frequently among the two classes of duller children. class 1 class 15 class 9 class 11 bright children dull dullest number of children 50 39 32 29 nose and throat conditions, number defective 6 4 9 9 _tonsils_ _3_ _4_ _3_ _3_ _adenoids_ _2_ _1_ _5_ _6_ deaf 2 5 1 catarrh 2 3 percentage of children, nose and throat defects 12 10·2 28·1 31 during the same year, another examination along the same lines was conducted in the william mckinley primary school,[8] where a large number of dull children had been grouped in special classes. [8]: cornell, psychological clinic, 2, 1909. none of these children were mentally defective, says dr. cornell, and only a few were really backward. the proportion of physical defect was found to be very large,--in 174 pupils, 188 physical defects (68 eye-strain, 40 nasal obstruction, 80 miscellaneous, 11 hypertrophied tonsils.) in a special class at the wharton school, numbering 22 children, 14 of the children suffered from adenoids, associated in 3 cases with enlarged tonsils. since no comparison is made with normal classes, this survey cannot be regarded as conclusive. wallin, in his book, "mental health of the school child," discusses several other investigations of the relation of intelligence to physical defect. only those studies in which were included adenoids and tonsil conditions will be reviewed here. those by ayres and cornell have been described above. in elmira, new york, says wallin, "an investigation of repeaters in the second grade showed that 21 per cent of those who required three years and 40 per cent of those who required four years to complete the grade had adenoids, as against only 19 per cent of those who required only two years to do the grade." another study described by dr. wallin was made by heilman in 1907 of 1000 camden repeaters. the correlation between pedagogical retardation and percentage of defect in each group was as follows: defects retardation 1 yr. 2 yr. 3 yr. 4 yr. 5 yr. per cent health 16·5 21·3 28·0 19·0 37·5 nutrition 13·4 8·9 17·2 20·2 17·5 _adenoids_ _6·2_ _7·3_ _8·1_ _9·6_ _7·5_ speech 5·2 5·1 4·2 10·5 20·0 visual defects 15·5 15·9 18·2 22·8 22·8 auditory 8·2 6·7 4·9 6·1 10·0 burpitt[9] describes an investigation of 400 children, 200 male and 200 female, considered by their teachers to be "dull and backward, but not to fall within the meaning of feeble-mindedness as given in the mental deficiency act of 1913." the children were examined for physical defects and other abnormal conditions. the author says that in 36 per cent of the cases, the cause for backwardness was found to be "inherent dullness." (the basis for judgment of inherent dullness is not given.) adenoids and tonsillar tissue were found in 18·75 per cent of the cases, and were "more prevalent than among the children of the area as a whole." [9]: h. r. burpitt. relative degrees of dullness and backwardness in school children and their causation. journal of mental science, 1916. the degree of retardation, based upon the number of school standards below normal, was ascertained for pupils who suffered from various defects. the relative retardation was expressed by the fraction n/(a-5) where n = number of years retarded, and a = age. eighteen per cent of the children were so retarded that the fraction was greater than 3-9. these were divided into two groups,--3-9 to 4-9 and 4-9 to 5-9. the results are given in the following table: causes 46 children 24 children 3-9 to 4-9 4-9 to 5-9 inherent dullness only 8 3 inherent dullness and one or more physical defects 7 2 irregular attendance with one or more physical defects 9 6 irregular attendance 2 3 _adenoids only_ _2_ _0_ turning to what the author calls single causes,--present in 170 cases out of the 400,- causes 151 children 19 children 1-9 to 3-9 3-9 to 6-9 irregular attendance 51 6 _adenoids_ _24_ _2_ inherent dullness 59 11 the term "cause" seems to be rather loosely used in this study. the author says concerning this, "dealing with physical defects first, although they amount in the aggregate to 53 per cent (omitting defective speech, which is a secondary condition), in 10 percent only do they represent the whole cause. this is made up of those cases where the defect is of such intensity as to produce retardation in otherwise ordinary children, and of other cases of less intensity, but sufficient to weigh down the balance against those near the level of what we may call for convenience the lower limit of normal intelligence." how he determines, without removing a defect, what the child's intelligence would be without it he does not explain. the following table compares the physical condition of two groups, one comprised of children examined in the regular routine examinations during the year 1912,--the other a group of retarded school

physical defects and pedagogical retardation. but whether or not the relationship is a causal one, they do not indicate. simple co-existence of two characteristics is not necessarily significant that one is cause of the other. plainly, though, if the removal of a physical defect is followed by improvement in the school progress, it may be argued that the presence of the defect was a causal factor in the previous retardation. the method in the few following studies, which seems to be employed to a greater degree than formerly, consists of measurement of such improvement. the journal of psycho-asthenics, march and june, 1918, contains a paper on the "results obtained from the removal of tonsils and adenoids in the feeble-minded," by wm. j. g. dawson, m. d. the author starts out rather discouragingly by regarding his hypothesis as an axiom. he says, "it is a well-known fact that hypertrophy of the tonsils and presence of adenoids may produce more or less dullness of the intellect in normal children. this is a result of the imperfect aeration of the blood which supplies the brain, on account of obstruction to respiration. in the feeble-minded, conditions are more or less similar." one hundred and twelve cases in the sonoma state home, eldridge, california, were operated on. of these 6 are recorded as borderline, 39 as morons, 50 as imbeciles, and 17 as idiots. adenoids were always removed when they were present. the results of the operation are as follows: number number before after operation operation mouth breathing 43 31 eneuresis 33 32 sore throats 70 2 ear trouble 19 2 change in voice 38 improved tonsillar tissue recurred in 5 general physical health 90 improved 6 borderlines 33 morons 42 imbeciles 9 idiots mental improvement from observation 27 improved 4 borderlines 15 morons 7 imbeciles 1 idiot the inaccuracy of this investigation is evident. the mental improvement was measured by "observation," which is at best inexact, and susceptible to the influence of any expectation of improvement on the part of the observer. the degree of improvement is not mentioned, nor is the time interval allowed for the appearance of such improvement. there is no control group, and consequently, no way of knowing whether the improvement was due to the removal of the defect. a similar, though rather more careful study is reported by dr. charles james bloom in the new orleans medical and surgical journal for april, 1917. dr. bloom's experiment consisted of eighteen months' observation on the mental and physical state following the removal of adenoids and tonsils from one hundred and fourteen children. this number was later reduced to fifty-seven, because of the fact that a number failed to return. there was no selection, all the patients being taken as admitted. the patient's physical and mental state was recorded at the time of admission. school reports were used as an index of intelligence. from this time on the patients were examined, weighed and measured at monthly intervals. the ages of the children ranged from four to fourteen years, inclusive. thirty-five per cent were under six years, and sixty-five per cent, therefore, over six. twenty-nine were boys, twenty-eight girls. omitting a part of the study which though interesting has no bearing upon our problem, we turn to results in the way of mental status. there were fifty-seven cases, ten of whom were under the school limit. of the remaining forty-seven, seven sent in no report. in four, or ten percent of the forty remaining, there was no progress. in thirty-six, or ninety per cent, appreciable progress was reported. one of the four unimproved cases was syphilitic, the other, the author says was a moron. quotation of the teachers' reports will be of interest. "'some improvement.' 'better work than previous year.' 'more effort displayed.' 'improved wonderfully.' 'improvement first term, not so much second.' 'before removal, not transferred; after removal transferred.' 'very much improved, both mentally and physically.' 'has made progress.' 'remarkable improvement.' 'not transferred before removal, but after.' 'more attentive.' 'a very small but gradual improvement.' 'am happy to tell you that he is studying more since tonsils and adenoids were removed.' 'greatly improved.' 'attention better.' 'more concentration.'" in this experiment like the preceding, the judges are liable to the effect of expectation of improvement. although the reports are more explicit, they are still couched in general terms, and not commensurable. some reports refer to intelligence and some to pedagogical standing. there is no control group. on the basis of these results, the author concludes: "children exhibiting some alternatives in the normal histology of tonsils and adenoids, give marked evidences of mental impairment." this seems to be a rather sweeping statement in consideration of the number of intellectually superior children who suffer from adenoids and diseased tonsils. another investigation was made by dr. cornell in the philadelphia schools,[12] where seventy more or less retarded pupils in grades one to four were operated on for adenoids. according to the teachers' reports- 30 per cent improved considerably. 40 per cent improved. 25 per cent did not improve. 1·6 per cent deteriorated. 3·0 per cent deteriorated considerably. of those who had two chances of promotion, 6·3 per cent were promoted twice. 16·0 per cent failed twice. 33·3 per cent were promoted once. 33·3 per cent failed once. with one opportunity, 11·0 per cent were promoted. 31·7 per cent failed. [12]: wallin: "mental health of the school child." 1914. "the promotion record was thus decidedly poor. it is possible, however, that the time for promotion came before the orthogenic effects of the operations had become effective." the same criticisms may be brought against this investigation as were mentioned in connection with the preceding ones. teachers' estimates of improvement, especially when such improvement is expected, and without means of measuring it objectively, are necessarily inaccurate. again there is no control group. of even less value are the results of an investigation in new york city by cronin, where, out of eighty-seven cases operated on for enlarged tonsils and adenoids, "many advanced three grades during the rest of the school year, and only three lost time." an interesting study is one that is described by john c. simpson, m. d., in the journal of the american medical association, april 1, 1916. dr. simpson's results are based on a study of 571 boys of girard college who had been operated on for adenoids and tonsils. improvement was studied along several different lines, among them scholastic ability. for this part of the study, 45 were chosen alphabetically, 3 from each section. the only selection was for boys who were operated on long enough after coming to school to give an idea of scholastic ability; and long enough before the present study to permit a judgment as to their improvement. monthly averages were taken of each boy up to the time of the operation and from then to the time of this study. they were based on an average of 100 per cent. as a control group, there were chosen 45 boys who had had no operation, and who lived and worked under the same conditions. they also were taken alphabetically, 3 from each section. the general average of the operative cases at the first measurement was 74·04. of these 25, or 55·5 per cent gave an average increase in monthly standing of 4·45 after operation, while the remaining 20, or 44·5 per cent suffered a decrease of 6·09. the average of the boys in the control group was 74·21 and for the first group after operation 74·06. "it is interesting to note," says the author, "that the standing of slightly more than half of those operated on was improved, but when compared with those not operated on, no difference is seen." in a similar study of younger boys who had undergone the operation on entering college, and who had since had a year's study (again a group of 45), the general average was 76·61. compared to 45 in the same classes not operated on, who had an average of 74·56, the operative group is very slightly superior, 2·05 points. another study of pedagogical improvement, and a valuable contribution, is that reported by a. h. macphail in pedagogical seminary for june, 1920, entitled "adenoids and tonsils; a study showing how the removal of enlarged or diseased tonsils affects a child's work in school." "the children studied were pupils in the adams and cranch schools. only cases were considered where there was a record of ten school months before the date of the operation, and where there was a record for at least ten month after the operation. there were thirty-one cases in all. "school records were looked up for the ten school months preceding operation, and for each school month subsequent--up to the date of leaving school, or in the case of children still in school, up to the date of the study. there were thus longer school records for some than for others. "the history of each case was divided into periods of ten school months each. eighteen cases had a record of twenty months after operation and eleven cases of thirty months. "comparing the first period after the operation with the period before, it is found that only about one-third showed improvement, and a little over half were doing poorer work. by comparing an average of _all_ work done subsequent to the operation with what was done before, it became evident that improvement in school work is not often observed until after a year from the date of the operation." in the cases that had records for twenty months, 16 show that better work was done in the second period after the operation than in the period before. table a table showing where improvement begins. _per cent of cases showing improvement_ period 1 period 2 period 3 based on 31 cases 32·2 based on 18 cases 33·3 66·6 based on 11 cases 36·3 63·5 100 based on all groups 33·9 65· 100 these cases were compared with a control group chosen at random. they comprised a total of 100 children who had records for four consecutive school years. table b table showing how time of improvement of "operated cases" compares with improvement among children at random. period 1 period 2 period 3 a--per cent of 31 cases 32·2 (operated upon) per cent of 100 children 42 at random b--per cent of 18 children--20 33·3 66·6 months (operated upon) per cent of 100 children at 42 41 random c--per cent of 11 cases for 30 36·3 63·5 100 months (operated upon) per cent of 100 children at 42 41 41 random "... immediately after operation, there seems to be a dropping off in the quality of school work done," but thereafter a marked improvement while the random group shows a comparatively static percentage of improvement from year to year. the conclusion of the author is: "here seems good reason to believe that the removal of diseased tonsils and adenoids is a factor in beneficially influencing the mental life of the school child. not only is the health impaired by failure to remove these diseased parts but the mental life and activity of the child as well." it is conceivable that pedagogical retardation might exist without any defect of intelligence. the physical effects of adenoids and tonsils might produce a tendency to fatigue, an emotional instability and consequent lack in attention, which would seriously influence the quality of school work, even though the child were of normal or superior intelligence. the relation of physical defects to intelligence has been investigated experimentally by a method which will be employed to some extent in the present investigation. in the two studies to which i refer psychological tests, rather than school standings were used as a basis for judging the intelligence. in each the effects of treatment were measured, and in one, a control group makes possible a more accurate interpretation of results. the first of these investigations is described by wallin.[13] it was "an attempt to determine by controlled, objective, mental measures the influence of hygiene and operative dental treatment upon the intellectual efficiency and working capacity of a squad of twenty-seven public school children in marion school, cleveland, ohio (ten boys and seventeen girls), all of whom were handicapped to a considerable degree with diseased dentures or gums, and an insanitary oral cavity." the experiment extended over one year, from may, 1910, to may, 1911. the treatment included corrective work upon the teeth and mouth, and also instruction in oral hygiene, and follow-up work by an employed nurse. five series of psychological tests were given at stated intervals during the course of the experiment. they included tests of immediate recall, spontaneous and controlled association (opposites), adding, and attention-perception (cancellation). there were six sets of each test, numbered from one to six, of equal difficulty, and given under uniform conditions. tests 1 and 2 were given before the treatment began, and the average was taken as the "initial efficiency." the last four, or the last two, were averaged to represent the pupils' "terminal efficiency." [13]: wallin: "mental health of the school child." 1914. the results show the following influence of dental treatment upon the working efficiency of the pupils. 1. the indices of improvement are about the same for boys and girls. 2. improvement was about the same for older and younger pupils. 3. there were great individual differences in initial proficiency and in improvement. 4. improvement in one test does not presuppose improvement in another. 5. there is a decided gain in every test, "and not only are the gains decidedly more frequent than the losses but the largest gains are invariably emphatically larger than the largest losses." 6. the average gains in the tests were: memory, 19 per cent with 8 losses and 19 gains. spontaneous association, 42 per cent with 2 losses and 25 gains, addition, 35 per cent with 1 loss and 26 gains. controlled association, 29 per cent with 0 losses. perception-attention, 69 per cent with 0 losses. average gain for all tests, 57 per cent. unfortunately, wallin was unable to form a control group, so that it is impossible to estimate accurately how much of this gain is due to the treatment of the defect, and how much to other causes, such as growth, etc. "but," the writer adds, "if we concede that one-half of the gain--and that is, i believe, a sufficiently liberal concession--is due to a number of extrinsic factors, such as familiarity, practice and increased maturity, the gain solely attributable to the heightened mentation resulting from the physical improvement of the pupils would still be very considerable. there is corroborative evidence to show that there was a general improvement in the mental functioning of these pupils. this evidence is supplied by the examination of the pedagogical record of scholarship, attendance and deportment. most of the members of this experiment squad were laggards, and repeaters, pedagogically retarded in their school work from one to four years, but during the experiment year only one pupil failed of promotion, while six did thirty-eight weeks of work in twenty-four weeks, and one boy finished two years of work within the experimental year." the second investigation was equally careful in its method. it was pursued by the rockefeller foundation, under the direction of e. k. strong, with the purpose of examining the "effects of hookworm disease on the mental and physical development of children." the children were divided into five groups and tested at intervals of three and one-half months. the tests used were opposites, calculation, logical memory, memory span, hand-writing, form-board, and binet-simon. after the first test-series was given, the five groups were divided into sub-groups on the basis of this initial performance, so that the improvement was compared only for those sub-groups in which this was equal. the improvement of group a--uninfected children--proved to be greatest, and was taken as 100 per cent. on this basis, group b--infected children not treated--showed the least improvement,--only 34 per cent. group c--children completely cured of infection--improved 60 per cent. group d--severely infected children, treated but not completely cured--improved 38 per cent, and group du--an older sub-group of d--improved 9 per cent as much as the normal children, and much less than the untreated younger children. dr. strong reaches the following conclusion: "the figures show, then, that hookworm disease unmistakably affects mental development. treatment alleviates this condition to some extent but it does not, immediately, at least, permit the child to gain as he would if he had not had the disease. and the figures apparently further show that prolonged infection may produce prolonged effects upon mentality,--effects from which the individual may never recover." chapter ii. method and procedure the following investigation was carried on during the year and a half from october, 1919, to april, 1921. the subjects were pupils at public school 64, manhattan, or patients at the manhattan eye, ear and throat hospital. all were boys, between the ages of six and fourteen years. the testing in the study of improvement was done by the investigator, assisted by three other examiners, all competent and experienced in the technique of giving psychological tests. a statistical study in addition to the more lengthy experiment, a statistical study was made, comparing the intelligence levels of two groups of children, the one selected for the presence of tonsils, the other for freedom from them. these two groups were obtained from a large group of 530 children whose i.q.'s were gained from the records of public school 64, where, so far as possible, all children are tested upon entering school. we had, therefore, a group unselected for intelligence level. all the children for whom we had i.q.'s were examined by the school nurse or physician. on the basis of this examination the two groups were selected. the tonsil group consisted of those cases which in the opinion of the nurse or doctor, were pronounced enough to deserve treatment. the normal group was composed of those who were not defective, or in whom the defect was so slight as not to demand treatment. the two groups were arranged each in a surface of distribution according to the i.q.'s of the members. the results of the distribution appear in table i, and in figs. i. and ii. a study of improvement after treatment the method employed here is based on the hypothesis that if a physical defect is the cause of retardation in mental or physical development, removal of the cause will tend to lessen the retardation. in other words, if a child's working efficiency is lowered by the effects of adenoids and bad tonsils, their removal should, unless such lowering be permanent, be followed after a reasonable time by an improvement. but improvement in efficiency, following the removal of adenoids and tonsils proves nothing unless we shall compare it with the change in efficiency of a control group, whose members have not been operated on, and who thus still suffer from the effects of the growths. selection of cases the selection of the children for the experiment was effected in the following manner. the teachers at public school 64 were asked to report any cases which had come to their notice, as being seriously afflicted with adenoids and diseased tonsils. in this way a fairly large group was obtained. the parents of the children were visited with the purpose of obtaining permission for examination and operation at the post graduate hospital. it was fairly easy to obtain permission to have the children examined. they were taken in groups of four or five to the clinic, the experimenter attending in person every examination in order to learn from the doctors the degree of the defect. as a result of this method, we discarded all those cases where there was any doubt as to the serious nature of the defect. from the large group examined, we were finally successful in securing operative treatment for 10 children. discarding the cases where defect was slight, there remained a number of children who, for one reason or another, did not undergo operation. in some instances the parents refused their permission, in some they failed to keep appointments, in one or two there was sickness in the family, and in a number the hospital was overcrowded and could not receive the children. all members of this group were examined,--to the number of fifty-six, and from them the control group was finally selected. since we were unable to secure a large test group from public school 64, the experiment was continued at the manhattan eye, ear and throat hospital where opportunity was given for testing the children after they had been admitted for operation. in order to be sure that in each case the defect was sufficiently pronounced to render decisive the results of the experiment, each child's card was examined. only those children were included who were undergoing operation for both adenoids and tonsils. it may be here remarked that mental tests were given to these children on the morning of operation, and in some cases only a short time before it. the possibility suggests itself, therefore, that the results of the tests may have been influenced by excitement or fright on the part of the patients. actually, however, this did not seem to be the case. the children were perfectly cheerful and showed no signs of nervousness. the tests were given in a waiting room with the door closed so that any disturbing sights and sounds were eliminated. the possible lowering of the performance by the causes mentioned would tend to exaggerate the improvement shown by the retests, so that in the light of the results, it will be seen that they could have had little effect. the test group, then, was composed of forty members; ten from public school 64, who received operation at the post graduate hospital, and the remaining thirty from various schools throughout the city, patients at the manhattan eye, ear and throat hospital. the control group of forty was selected as previously described, and the pairs were arranged so as to have the ages of the members of one pair as nearly as possible the same. the tests since the main interest of this investigation lies with intellectual development, two tests of intelligence were given: namely, terman's revision of the binet test, and healy's picture completion test, number ii. the starred terman was always used, since it was necessary to economize time. it was expected that improvement in general health would probably follow the removal of the defects. this physical gain should come to light in increased height and weight. in every case, therefore, height and weight were measured. it is conceivable that adenoids and tonsils might have no effect upon general intelligence, and yet might cause a noticeable pedagogical retardation, simply as a result of the child's physical handicap, tendency to fatigue and consequent defect in attention or sustained effort. in order to gain some measure of this physical factor, strength of grip and speed in tapping were found. an effort was made, also, to obtain teachers' estimates of the pedagogical rankings, but this was for the most part unsuccessful, since in many cases teachers misunderstood directions, and in others the tests were made too soon after the opening of school for any such estimates to be possible. the tests described above were given before the operation to each child in the test group, allowing as short an interval as possible between test and operation. in the case of the manhattan hospital children, test and operation fell on the same day. in no case did the interval exceed ten days. the members of the control group were tested, each one within a week of his partner.[14] [14]: in a few cases where the operation was postponed after the test had been given, the child and his control were retested just previous to the operation. since both cases were retested, practice effect is of no great importance. six months after his first test, each child was retested, whenever possible. since some children had dropped out of the groups for one reason or another, the final number in each group was twenty-eight. it was necessary to rearrange the control cases somewhat in order to fill in spaces left vacant by those who were lost. in this rearrangement, the effort was made, 1. to pair cases whose ages were approximately the same; 2. to pair cases whose first tests were dated fairly close together. since all the children were tested and retested under approximately the same conditions, this rearrangement will probably not greatly influence the results. the tests were always given in the same order. the following table shows a list of the two groups, as originally paired, and as finally rearranged, with dates of tests and retests. dates of operation are given for the first group. test case original control final control test i op. test ii test i test ii test i test ii jb 10-15-19 10-20-19 lost ss 10-15-19 4-15-20

discussion of the results statistical study the statistical study compared two groups of cases in respect to i.q. these groups were selected from one large group, on the basis of presence or absence of tonsillar defect. the tonsil group was composed of 236 cases, and the normal group, of 294. the distribution of the two groups according to intelligence is set forth in table i, and in figs. i and ii. table i tonsil group normal group i.q. no. of per cent of no. of per cent of cases cases cases cases 4050 2 ·8 0 0 5060 1 ·4 2 ·7 6070 7 2·9 4 1·4 7080 21 8·9 29 9·8 8090 45 19·0 52 17·7 90-100 80

evident that the two groups are practically equal in intelligence. the average i.q. for the normal group is 95·4, as compared with 94·9 for the tonsil group. the medians are equally close,--95·6 in the normal group and 95·3 with the tonsil cases. the difference in variability is negligible, q being 8·705 and [sigma] 14·4 in the tonsil group, while in the normal q is 8·27 and [sigma] 12·2. the two cases with the lowest i.q.'s were tonsil cases, but the three highest i.q.'s also belong in this group. fig. 1. distribution of i.q.'s. number of cases. fig. 2. distribution of i.q.'s by percentage of total number of cases in the group. if the frequencies are expressed in terms of per cent of the total number of cases in the group, the two may be compared further. the following details are noticeable. i.q. per cent of per cent of tonsil group normal group below 70 4·1 2·1 below 90 32·0 29·6 above 110 10·9 11·1 above 120 3·7 3·0 above 130 1·2 0 in other words, in the percentage of cases below normal intelligence, the tonsil group exceeds by 2·4 per cent. the percentage of defective cases is also slightly greater in the tonsil group--the difference here being 2 per cent. the normal group has a negligible predominance of bright cases,--only two-tenths of one per cent difference, while with the very superior cases, the tonsil group again exceeds,--by 1·2 per cent. the per cent of the tonsil group which reaches or exceeds the median of the normal is 49 per cent. these figures seem to indicate remarkable similarity between the two groups considered. the two distributions are almost identical. while the slight predominance of cases below normal mentality in the tonsil group may indicate a very feeble tendency toward coincidence of tonsillar defect and mental dullness, it does not seem large enough to be at all significant. this is especially true when we consider that the tonsil group exceeds in superior children. if we allow the preceding contention of coincidence between dullness and tonsils, must we not argue here in the same manner for a tendency toward coincidence of superiority and tonsils? the chief source of error in this part of the study is the fact that the throat examinations were not conducted by the same person throughout the investigation. for this reason there must have been some slight disagreement as to what should constitute a reportable case. in the event, then, of a positive relationship between tonsil defect and lowering of the intelligence quotient, placement of normal tonsils in the "tonsil" group, and of diseased tonsils in the "normal" group would raise the first, and lower the second, thus tending to conceal the difference between the two. on the other hand, the cases where disagreement would occur would naturally be those of slighter defect, in which the intellectual retardation would be less likely to occur, so that the result would probably be merely an increased height at the overlapping portion of the curves, with no change at the ends. in any case, the two examiners had worked together previously, so that each must have been somewhat familiar with the opinions of the other. they were aware, also, that pronounced tonsillar defect was what we were attempting to detect. however this may be, there must always be some disagreement in diagnosis. when this is allowed for, the results of the investigation may be taken for what they are worth. contrary to expectation, there seems to be very little difference in intelligence between a group of children whose throats are normal, and one in whom the tonsils are diseased or badly enlarged. study of improvement after operation the complete results of the tests and retests are collected in table ii, where each control case is listed immediately below its respective test case, and where age, height, weight, grip, tapping rate, i.q., and score in healy picture completion are shown. from these data the more detailed observations have been made. the improvement of each child in the various tests has been computed, and a comparison drawn between the two groups. as we have previously stated, any improvement shown by the test group in excess of that of the control group, may be looked upon as significant. let us consider first the improvement of the children in general health, as shown by height and weight. in tables iii and iv we have tabulated the results, in such shape as to permit of comparison. an inspection of these tables will establish the fact that after a six months' interval, the test group shows, in respect to height and weight, a very slight gain over the control group. in weight, the average of the amounts by which the test group gains exceed the control group gains is 1·37 lbs., and in height, only ·16 inches. the medians of these amounts are 1·2 lbs. and ·2 inches respectively. comparing the improvements for the two groups, we find that in the case of the weights, the smallest gain (a loss of 1·2 lbs.) occurs in the control group, while the largest gain (10·7 lbs.) is in the test group. table ii. results of tests blank spaces indicate where tests were omitted for one reason

i.q.'s to be compared 21 pairs of weights 19 pairs of heights 16 pairs of grip measurements 20 pairs of tapping speeds 24 pairs of healy completion scores. again, in only five pairs does the gain of the control exceed that of the test case, while in the remaining sixteen pairs the gains of the test cases are greater than those of their respective controls. the greatest loss of test as compared to control is 4·2 lbs., while the largest gain is 7·9. it would seem then, that after a six months' interval a child who has been operated on for adenoids and tonsils will tend to show a slightly greater increase in weight than a child who continues to suffer from the defects. the very small group renders this conclusion far from assured. since it doubtless takes some little time to recover from the effects of the operation, and since there is comparatively little gain in weight in a six months' interval, it would be well to extend the experiment over another year. for the greater reliability of results, some degree of after-care should be given the operative cases, the control cases of course receiving the same treatment. while this was impracticable in the present study, it happened that three pairs of cases were members of a nutrition class, and therefore underwent some hygienic treatment. in one pair, (no. 11) the test case lost ·3 of a pound, while the control gained ·9. the test cases of pairs 7 and 10 gained ·8 lb. and 2·1 lbs. respectively, over and above their controls. however, these three cases alone are of little significance. a study of increase in height suffers even more than one of weight gains from the short interval which elapsed between measurements. normally, there is very little growth in six months. there are only nineteen pairs of cases in this portion of the study, a fact which renders it of even less value. however, results are offered for what they are worth. the smallest increase in height (·3 in.) is in the test group, while the greatest growth (3·5 in.) is also in the test group. there is, however, a gain of 3·3 inches in the control group as well as one of only ·4 inches. there are seven pairs in which the test group growth is less than that of the controls, one in which the two are equal, and in the remaining eleven the growth of the test cases exceeds that of the controls. the variability table iii gain in weight, 6 months, 21

improvement in intelligence after six months than those who had been afflicted for a longer space of time. we had no way of knowing definitely how long the defects had been present in the cases studied. roughly, though, we may say that in general the older boys have had defective tonsils and adenoids for a longer time than the younger ones, and that the older the boy, the older the defect. on this basis, if correlation of youth with gain in i.q. should give a larger positive value for r, we might be justified in saying that the younger boys, who have been handicapped for a lesser period, show greater mental recuperation than their older companions. such a correlation was attempted in the test group, correlating age at the first test with gain in i.q. the same methods and formulae were used as in the weight and intelligence comparison, the greatest gain in i.q. being given first position, and the lowest age. the resulting value for r was -·24, with an unreliability of ·186. the relationship would appear to be in the other direction but it is so small, with an unreliability measure so large as to be insignificant. once more, then, we find in our results no correspondence between recency of defect and quick mental recovery. table xi showing percentile ratings of the members of the two groups at the beginning and end of the six months' interval weight

table ii, with the scores given in percentile values. in each test, the group was taken as composed of the two scores of every individual--the total number of scores in tests and retests, eliminating those scores where the other member of the pair was lacking, or where no retest was given. thus case number 1 was just within the lowest 27% of the group in weight at the first weighing, but had advanced to the 44 percentile at the second. in height he gained from the 25 percentile to the 40 percentile. his total gain in all tests is 30 percentile out of a possible 415, and the average gain is·.05. the reader may see by scanning the table that the gains in the test group are practically equaled by those in the control group. there seems to be no consistent relationship between a low score in the first test and a large gain. this is true even though the method of calculation tends to minimize gains at the high end of the group, and losses at the low end. in table xii this may be seen more clearly in respect to i.q. and the results for all the tests taken together with the i.q. weighted by being counted twice. a large possible gain indicates that the score at the first testing was low, and vice versa. considering i.q. values, the largest possible gain in the test group was 95 per cent of the group. this occurred twice, in one case the actual gain being 7% of the group and in the other 2%. in the control group, the largest possible gain was 97% of the group, but actually this case fell 1% of the group. if we correlate possible gain with actual gain for each group, using

small number of cases involved the probable error is too great to allow either of these measures as indicative of relationship. we may say, then, that there is no definite tendency for those of low i.q. to improve in six months after operation to a greater degree than those of higher i.q. finally, in order to compare the results of the various tests, the measures of the gains of the test group in excess of the control were, for each test, expressed in terms of p. e. the averages and medians of these measures are collected in table xiii. they show a very slight tendency toward gain in weight, height, and weight-height-age relationship; neither improvement nor loss in grip, tapping fatigueability and i.q., and a rather curious tendency to loss in the healy scores. this latter is very probably not a true measure since performance in the healy picture completion test shows a rather high variability, and the cases are so few as to make the influence of single very high or low scores unduly great. table xiii showing improvement in various tests of operative group over and above such improvement in control group. expressed in terms of p. e. weight height height grip tapping

improvement after a second interval of six months in view of the fact that one of the experimenters[15] found improvement in school work when her study was extended to cover a second time interval after operation, it was deemed advisable to similarly extend the present investigation in order to determine whether our operated cases showed any improvement after twelve months. to this end, the fifty-six children composing the final groups of the first study, were sought after a second interval of about six months. conditions made it impossible to give all the retests exactly twelve months from the time of the operation. as a matter of fact, the period ranges from ten to seventeen months. an effort was made to keep the interval between tests equal for the two members of a given pair. [15]: a. h. macphail, adenoids and tonsils: a study showing how the removal of enlarged or diseased tonsils affects a child's work in school. ped. sem., june, 1920, pp. 188-194. the same tests were given as in the first study. about half of the testing was done by one of the former examiners, but she was obliged to turn the work over to another before it had been completed. the second examiner was highly recommended, and had had training and practical experience in the giving of tests. she was instructed in the methods which had been employed previously, so that conditions were as far as possible kept constant. the results of the tests are collected in table xiv. in the first column is given the length of the time interval for each case. it may be seen that the final group was composed of forty-two children, forming twenty-one pairs. there were fifteen pairs which received a second rating in weight; thirteen in height; thirteen in grip; fifteen in tapping, eleven in fatigue as shown by tapping, twenty-one in i.q., and eighteen in the healy test. these numbers while they are smaller than we could wish, would seem to be great enough to indicate table xiv results of the tests after an interval of from 10 to 17 months n[16] mos. weight height grip test 1 test 3 test 1 test 3 test 1 test 3 1 15 50·4 63·5 46 49·7 13 18 1c 15 53·5 62·8 46·4 49·7 11 15 2 15 40·9 47·9 42·6 45·9 9 10 2c 17 52·3 65·5 45·2 49·8 10 15 3 16 55 67·5 47 50·2 12·8 13 3c 14 61·5 57·8 51·7 54 14 14·5 4 13 51·1 60·2 47·5 50·5 9 4c 13 49·4 54·2 48·9 50·8 9·5 7 14 39·9 45·8 42·9 45·6 7 6 7c 12 38·4 42·1 41·9 43·7 9 14 8 11 60·8 69·2 50·8 52·3 10 8c 11 45·4 57·9 36·8 48·7 15 10 11 48·9 56·7 46·1 48·6 12·5 12 10c 11 47·1 51·8 45·6 48·1 10 12 11 12 47·8 55 45·8 49·5 11 11 11c 12 41·6 47 43·6 46·8 11·5 7·5 12 12 48 66·5 44·8 14 12c 11 41 69·6 41·5 6 13 12 90 112 61·3 61·8 26·5 28·5 13c 12 74·7 88 56·8 60·0 22 27 14 12 56 66 51 53·3 16 17 14c 12 81·9 98 57·9 59·5 22 22·5 15 12 57·5 51·1 15·5 15c 10 67·2 50·1 15 16 12 56 60·3 51·6 53·5 19 18·5 16c 11 51·2 55 48·7 50·1 10 10 18 12 58·2 47·3 18 18c 11 45·3 46·7 8 19 12 90 108 57·7 60·5 22 20 19c 11 52·4 59 46·7 48 15 18 20 12 44·2 47·2 11 20c 11 61·3 49·6 15 21 12 70·7 85·5 54·1 16·5 15 21c 10 62·4 69·2 49·6 19 17 23 12 51·7 47·8 11·5 15 23c 11 64·1 51·4 14·5 16 27 12 43·7 45·4 9 6 27c 11 41 44·6 8 9 28 12 71·3 78·5 54·9 56·3 23·5 28c 11 74·2 85·8 53·4 55·9 21 table xiv (continued) n[16] tapping i.q. healy test 1 test 3 (1) (3) (1) (3) 1 135 142 82 93 -25 11 1c 106 134 80 85 -50 11 2 105 135 107 113 28·5 24·5 2c 152 139 91 86 3 19·5 3 136 144 94 91 21·5 15·5 3c 135 135 82 96 17 25·5 4 103 96 111 8·5 4c 109 83 102 33 7 125 91 93 6 16 7c 105 95 112 4·5 11 8 113 128 91 92 32·5 8c 131 121 98 111 4 10 68+ 74 145+106 110 116 -12 11 10c 70+ 74 148+124 104 107 27 48·5 11 125+ 90 120+125 103 102 8 15·5 11c 155+125 102+112 101 95 -29 -20 12 98+ 69 98 86 20 1 12c 102 98 90 -10 41·5 13 160+165 176+187 70 61 43 62·5 13c 150+109 188+174 66 60 -1·5 21·5 14 190+172 228+215 96 102 12·5 77 14c 175+152 165+186 140 138 5 48·5 15 172+167 192+186 97 97 7 19 15c 140+115 145+133 78 98 1 54·5 16 145+131 65 74 49 79 16c 145+ 99 74 81 30 45·5 18 133+115 126+145 98 101 -13·5 13·5 18c 100+ 99 108+ 92 90 92 -32 -35 19 168+136 96 97 57·5 60·5 19c 100+115 98 90 -22 -15 20 105+115 122+118 106 116 0 55 20c 150+120 154+154 118 140 30 48·5 21 152+111 154+155 64 66 20 38 21c 140+136 174+150 86 93 70·5 88 23 150+119 157+157 85 80 49·5 62·5 23c 122+115 141+141 81 88 4 64 27 108+ 92 114+ 95 110 112 -25 25·5 27c 115+105 101+118 72 98 2 39·5 28 150+148 176+168 81 83 29·5 77·5 28c 178+148 172+157 95 94 64·5 83·5 any very consistent tendency toward improvement. the question, whether or not the results are affected by the differences in time interval, will be considered later. in weight, the test group showed an average gain of 11·013 pounds, with a median of 9·1 (table xv). the average gain of the control group was 9·113 pounds and the median 6·8. the gains in the test group are less variable than those of the control. the average of the gains of the test group in excess of those of the control is 1·9 pounds, and the median is 2·2 pounds; while the unreliability of the difference is ± 1·46 the average, then, is only 1·30 p. e. and the median 1·51 p. e. if we turn to table iii and compare the results there set forth with the results at the end of the second period, we find the gains of the test group exceed those of the control in the following manner. table xv weight, second retests, 15 pairs n[16] test group (a) control group (b) test 1 test 3 gain test 1 test 3 gain a-b 12 48 66·5 18·5 41 69·6 28·6 -10·1 2 40·9 47·9 7 52·3 65·5 13·2 -6·2 14 56 66 10 81·9 98 16·1 -6·1 28 71·3 78·5 7·2 74·2 85·8 11·6 -4·4 8 60·8 69·2 8·4 45·4 57·9 12·5 -4·1 16 56 60·3 3·7 51·2 55 3·8 -·1 11 47·8 55 7·2 41·6 47 5·4 1·8 7 39·9 45·8 5·9 38·4 42·1 3·7 2·2 10 48·9 56·7 7·8 47·1 51·8 4·7 3·1 1 50·4 63·5 13·1 53·5 62·8 9·3 3·8 4 51·1 60·2 9·1 49·4 54·2 4·8 4·3 21 70·7 85·5 14·8 62·4 69·2 6·8 8 13 90 112 22 74·7 88 13·3 8·7 19 90 108 18 52·4 59 6·6 11·4 3 55 67·5 12·5 61·5 57·8 -3·7 16·2 av. 58·45 69·50 11·01 55·13 63·58 9·11 1·9 m 9·1 6·8 2·2 75%ile 13·52 12·67 5·22 25%ile 7·15 4·47 -4·07 q 3·18 4·1 4·65 p. e.

indeed, it has very nearly doubled. 2. gain in height, resulting from operation, is so slight as to be unreliable. this gain does not increase during a second period of six months. 3. the height-weight-age relationship is an excellent measure of the physical well-being of the child. the figures expressing this relationship show no very reliable gain in the first six months, but improvement increases considerably during the second period. 4. the test group shows no gain over the control group in strength of grip. there seems on the other hand to be a slight loss; which does not decrease in amount during the second period. 5. speed of tapping did not increase during the first period, any more for the test group than for the control. during the second period, however, there is a marked improvement. 6. operation for adenoids and tonsils does not lessen fatigueability as shown by the tapping test. the probability is, however, that the test is at fault. 7. no rise in i.q., as a result of operation, makes itself evident after six months or after twelve months. 8. there is no improvement in the performance of the healy test either after six months or after twelve. 9. in every test except grip and tapping, there is a marked increase in the variability of the gains after the second period. this is possibly due simply to the fact that the longer interval permits the intervention of more extraneous factors which may influence the scores in one direction or the other. 10. a group of 236 children with diseased tonsils showed equal distribution of i.q. with a group of 294 children who were normal in this respect. conclusions the article by macphail, which has been reviewed in a former chapter, showed pretty conclusively that the removal of adenoids and tonsils was followed by improvement in school work. that such improvement was not due to a rise in general intelligence can be concluded from the present experiment. that efficiency in school work does not rest wholly upon intelligence has been demonstrated more than once. the tendency here noted to improve in general physical tone may, perhaps, serve as a sign of the factor upon which such improvement depends. improved health means better attention, better emotional response, greater resistance to fatigue, and probably increased efficiency. interesting investigations of such improvement in efficiency might be made by administering educational tests to groups similar to those of the present study. the results of such an experiment would be exceedingly instructive, and would be more significant than conclusions drawn from school marks. by this means also we might determine along what special line efficiency is most affected. since there was no recuperation in intelligence resulting from operation for adenoids and tonsils, it is reasonable to expect that there had been no retardation from which to recuperate. this supposition is borne out by results of the statistical study, wherein we found that a group of children suffering from diseased tonsils possessed equal intelligence with a group which was free from such defect. we can say to physicians, then, with fair amount of assurance, that removal of adenoids and tonsils will probably not raise to any great degree the intelligence level of the mentally defective child who is brought to him. we can say to students of the constancy of the i.q., that it is not greatly lowered by adenoids and diseased tonsils and we may say to the clinical psychologist that these defects have no demonstrable effect upon general intelligence, whatever effects they may have on volitional and emotional normality,--the two elements which, along with intelligence are necessary for the maintenance of the individual as an instrument of social efficiency. on phlebitis. ----"whose effect holds such an enmity with blood of man, that, with a sudden vigour, it doth posset and curd, like eager droppings into milk, the thin and wholesome blood." hamlet. plate shewing the first morbid appearance produced by the stagnation of vitiated blood in the capillaries of the lungs.

[illustration: coat of arms] london: henry renshaw, 356, strand. 1850. london. richards, printer, 100, st. martin's lane. preface. since the period when humoral pathology fell into merited disrepute, comparatively few attempts have been made, to define with any degree of accuracy, the conditions under which morbid secretions may find their way into the circulation. the diseases produced by the presence of vitiated fluids in the general system, and in parts of the body at a distance from their original source, have received more attention; but they are still far from occupying that position in our systems of medicine and surgery which their importance deserves. the difficulty of tracing diseased secretions after they have become mingled with the blood, or of recognising their presence in the vessels, has rendered the investigation of their actions often tedious and inconclusive; while, on the other hand, the changes of structure in solid parts, readily appreciated by the senses, have been more calculated to arrest the attention, and to afford that ready solution of the origin of the symptoms which, whether imaginary or real, has a tendency to relieve the mind from farther doubt and suspense. hence it has happened, that the pathology of the solid parts of the body has received a very disproportionate share of attention. most of the observations which have tended to advance our knowledge of the effects of the introduction of diseased fluids into the blood, have been recorded under the name of phlebitis or inflammation of the veins; and i have retained this title, although it is obviously inadequate to express those constitutional affections which form the most important and characteristic features of these complaints. the introduction of pus into the system has justly been regarded as the most important of this class of diseases. but the theory of the circulation of pus globules with the blood, supported as it has been by much ingenious reasoning, and most conveniently adapted to explain the formation of purulent deposits, has yet never obtained general belief. the stoppage of the pus globules in the capillary tubes, has appeared to many accustomed to the practical observation of diseases, too mechanical a solution of the origin of these abscesses; and it has become necessary to determine, with more precision than has hitherto been done, the actual conditions under which pus in substance can be received into the circulation. the simple experiment of mixing some pus with healthy, recently drawn blood, will at once shew that such a combination cannot circulate in the living body. it will be found that the blood coagulates round the globules of pus, and forms a solid mass which will adhere to the first surface with which it comes in contact; and it will be evident, that it is not till the coagulum thus formed is broken up or dissolved, that its elements can circulate with the blood. it appears not a little surprising that this, perhaps the simplest and the most instructive experiment that can be performed in reference to the subject of the formation of purulent deposits, should not have been resorted to in preference to others which have been difficult in their execution, and inconclusive in their results. it has been remarked by sir charles bell, that we can seldom rely upon the answers that are extorted from living animals by experiments which go counter to the natural feeling of mankind; and that it is our duty, if experiments are performed, at all events to prepare for them by the closest previous application of our reason, and so to narrow the question as to be certain that advantage may be gained by our proceedings. had the simple experiment mentioned above, illustrating the action of pus upon blood out of the body, been duly considered, it might have saved some of the vague and useless experiments which have been performed upon living animals in the investigation of the present subject. _sept. 1850._ _13, dover street, piccadilly._ part i. on inflammation of the veins: with experiments illustrating the effects of a vitiated condition of the blood. i. john hunter expressed his belief that the blood has "the power of action within itself",[1] and that when it coagulates, it does so in consequence of an "impression" which it receives. such an impression may be communicated by separation from the living vessels, or from "cessation of natural action"[2] in them. in certain circumstances also the living vessels themselves may be the means of exciting coagulation.[3] in others, the admixture of extraneous substances may either retard or hasten this operation.[4] the experiments made to determine the last point, mr. hunter informs us, "were rather imagined than fully carried out; and the subject rather broached and touched upon, than prosecuted".[5] in these experiments, different articles used in medicine were mixed with portions of blood taken from the body; and it was found that, in some cases, they altered both "the time," and "the firmness of the coagulation".[6] the circumstance of medicines being used in such experiments, conveys the idea, that, in instituting these researches, hunter conceived that substances which would tend to produce such actions out of the body, might likewise produce some effect upon the blood in living animals. in endeavouring to prosecute the idea thus thrown out, i have been led to try the effect of different substances upon the blood, and to consider the changes which may be produced in that fluid, by the admixture of animal secretions. the experiments which will be hereafter detailed, not only confirm mr. hunter's notion, that foreign substances may induce actions in the blood when withdrawn from the body, but also show that some of these effects may be produced still more rapidly in the living vessels. [1] hunter on the blood. ed. 1794, p. 21. [2] p. 25. [3] p. 24. [4] p. 97. [5] p. 94. [6] p. 98. in these experiments, pus was used in preference to any other fluid; first, because the power of coagulating the blood which it was found to possess, enables its influence to be traced within the body; and secondly, because, being an animal secretion, the results obtained are likely to be analogous to those produced by the admixture of other secretions with the blood. when pus is mixed with blood, fresh-drawn from a healthy animal, it is found in a marked manner to favour coagulation. this effect does not take place immediately, as in the case of the mixture of an acid with the blood; and i have reason to believe, that where the blood has lost its natural power of coagulation, no visible change is produced in it by the addition of pus. it appears, therefore, that this effect depends rather upon a vital than a chemical influence. in some cases, the coagulation takes place in less than two minutes; in others, after a longer period; but in all the experiments made, the influence of pus, when added to blood, in promoting its coagulation, was sufficiently evident. putrid pus was found to act more rapidly than healthy pus (exp. 1, _b_), but the admixture of water was found to retard the operation; the result, in this respect, differing in some degree from the conclusion drawn from a similar experiment performed by hunter.[7] the causes which usually favour coagulation out of the body, are rest, and separation of the blood into small quantities. these conditions are, in some degree, brought into play during the circulation of the blood through the capillaries; and when the influence of the admixture of pus with the blood is not sufficient to produce coagulation at once, we should naturally expect the effect to be more readily induced, where these two additional causes concur in favouring such an action. when the pus introduced is in any large quantity, the coagulation of the blood is at once determined, and the entrance of pus into the circulation thereby prevented. the experiments vi, vii, and viii, appear to furnish evidence of the correctness of this opinion, and to show that the result may be produced more quickly in the vessels than elsewhere. in these cases, so sudden was the effect, that the mixture of blood and pus coagulated before it could traverse the jugular vein, as indicated by the induration and cord-like feeling of the vessel. [7] op. cit. p. 98. in experiment viii, the obstruction formed was sufficient to resist even firm pressure, and in a great measure, if not altogether, to prevent the pus injected from finding its way along the vein. the coagulum was felt in the vessel during the operation, and was there found after death. one effect of the coagulation of the blood thus immediately produced, is necessarily to retain the vitiated blood in the part, and to prevent its being carried in the course of the circulation. this intention may be interfered with, either by accident or design. the coagulum, as in experiment vi, may be broken up during the process of its formation, or after it has formed, and the parts of which it was composed carried forward with the circulating blood. in such a case, the vein in which the coagulum first formed, is found in its natural condition (except at the part where it may have been mechanically injured), and dark patches of congestion may be found in distant systems of capillaries. if the coagulum be allowed to remain, the vein in which it is formed soon becomes thickened; but, as the experiments cited prove, _this thickening is the effect and not the cause of the stagnation of the vitiated blood in the vessel_. ii. when blood coagulates in a serous cavity, a thin pellicle forms upon its surface, and, becoming thickened by deposition from the fibrin of the blood, forms a cyst, which completely circumscribes the effusion. this point has not probably received the attention which it deserves; and as it is believed to be of primary importance in the investigation of the present subject, a short space will be devoted to the purpose of fully establishing it, and tracing its connexion with other and subsequent changes. every layer of lymph observed upon dissection, has perhaps too generally been considered as the result of inflammation; and hence there has arisen a confusion in the terms employed. that lymph may be derived from the blood directly, and deposited in the form of a membrane, without being secreted by any vessel, has been fully shown by a paper in the _medico-chirurgical transactions_.[8] such layers of lymph assume so much the appearance of others, derived by secretion from inflamed capillaries, that they have been described as identical. but the mode of their formation in the two instances is altogether different. in the one case, the process is a local one, confined to the blood itself, and subsequently to the membrane with which it happens to be in contact. in the other case, it is an effort of the constitution, accompanied by constitutional symptoms. the former of these processes was clearly described by hunter. in describing the process of union by the first intention, "coagulation", he says, "i imagine to proceed upon exactly the same principle as the union by the first intention. it is particle uniting with particle by the attraction of cohesion, which, in the blood, forms a solid; and it is this coagulum uniting to the surrounding parts which forms the union by the first intention: for union by the first intention is no more than the living parts when separated, whether naturally, or by art, forming a reciprocal attraction of cohesion with the intermediate coagulum, which immediately admits of mutual intercourse, and, as it were, one interest."[9] "when the blood has coagulated, so as to adhere to both surfaces and to keep them together, it may be said that union has begun."[10] "the uniting medium becomes immediately a part of ourselves, and the parts not being offended at it, no irritation is produced." "if the quantity of blood extravasated be large, the whole will not become vascular, but the surface only, which is in contact with the surrounding parts."[11] the process thus described in general terms may take place in serous cavities. in the third plate at the end of mr. hunter's work, is represented a coagulum of blood adhering to the _tunica vaginalis_. "the adhesion was firm, though it admitted of a separation at one end; when separated, fibres were seen running between it and the testis." [8] vol. x, p. 45-82. [9] op. cit. p. 26. [10] p. 200. [11] p. 205. it might seem unnecessary to dwell upon this process further, had not some of the highest authorities in surgery, both here and on the continent, described it as identical with adhesive inflammation. thus bichat[12] says, "the cicatrization of wounds in veins after bleeding is a result of inflammation." now, it is submitted, that when the blood coagulates, either in serous cavities or in veins, the process of union is not usually one of inflammation, or one in which the powers of the constitution are called into increased activity. it is true, that in both cases, inflammation may take place, and lymph, as the result of such inflammation, may be secreted; but this is only when, to use mr. hunter's language, the "primary intention" has not been fulfilled.[13] [12] anatomie générale, vol. ii, p. 423. [13] in speaking of the two principles, i shall use the term by "first intention", to designate that the fibrin is derived from coagulated blood; and restrict the term "adhesive inflammation" to indicate the effusion of lymph from inflamed vessels. when a membranous layer of lymph is deposited from effused blood, it adheres with some firmness to the surface with which it is in contact; but, as there is at first no vascular connexion established between them, it may be separated, leaving the part to which it adhered in its natural condition. lymph derived from adhesive inflammation, on the other hand, when separated, leaves the surface upon which it was formed rough and uneven. coagulated fibrin, when recently deposited, may thus be distinguished from effused lymph. the changes which blood undergoes when effused in serous cavities, may likewise take place when it is detained in injured or exposed veins. the coagulation of the blood in such cases (exp. vii and viii) serves as a bond of union between the sides of the veins (which may be either temporary or permanent), so as to prevent the entrance of any foreign matter into the circulation. when the blood thus coagulates in veins, changes may be produced analogous to those mentioned as occurring in serous cavities. if the quantity of blood be large, a thin pellicle is at first formed upon its surface (see preparations 1523-25 and 1525-64, in the museum of guy's hospital). this membrane becomes thickened and adheres to the internal surface of the vein (see plate no. 13, cooper and travers' _surgical essays_, part i, and prep. no. 1736, in the pathological museum of the college of surgeons). it then becomes vascular, and finally so firmly united to a part of the circumference of the vessel as to be inseparable from it, without lacerating its lining membrane. if the wounded vessel be small, or if the animal be strong and robust, the whole of the blood in the vein may at once coagulate and become united to its sides. the usual economy of nature, however, is here exercised, with a precision proportionate to the strength of the patient. a simple wound in a vein, in healing by the first intention, will not obstruct the circulation through the vessel under ordinary circumstances. a coagulum will form, sufficient to unite together the divided edges, and the circulation of blood through the vessel will be uninterrupted; but if the wound does not readily heal, coagula may form, which encroach more or less upon the cavity of the vein. there are then three ways in which a coagulum may obstruct the circulation through a vein. 1. by the outer layer of the coagulum forming a membrane, which contains the more fluid parts of the blood. 2. by the whole of the blood contained in the vessel forming a solid coagulum. 3. by a coagulum adhering to the injured side only of the vessel. in whichever of these ways the process of repair is commenced, it may be interfered with, and the union dissolved. this is practically known to farriers; who, when they want to bleed a second time from the same orifice, break down the "union by the first intention" by a blow upon the vein. during the time that the parts are united only by the fibrin from the blood, any violence must tend to produce the same effect. if the constitution is good, and the coagulating power of the blood unimpaired, the union may be frequently interrupted, and yet be as frequently re-established in the same way. when from any local cause, or from any constitutional peculiarity, the union by the first intention fails at the seat of the injury, it may yet be attempted at some distance up the vein; and then we have coagula formed at different distances along the vessel. if these coagula fill the vein, are firm, and remain undisturbed by violence, the union may be complete, and the vessel sealed at those parts, even although the original wound should suppurate. but it sometimes happens, that the same peculiarity of constitution, or the same local cause, which prevented the union at the original wound, may prevent complete union by the first intention at any other point of the vein; and then its canal is open to any secretion that may be introduced into it. foreign matter may thus find its way along a vein; but still there is a provision against its being carried the round of the circulation. it has been already shown that the blood, when in a natural condition, has a tendency to coagulate around pus, and, probably, many other fluids, even out of the body (experiments i, v), and that this property is exercised in a still more remarkable manner in the living vessels (see experiments vii, viii). foreign matter, even after it has got into the veins, may then, by the same means, be prevented from proceeding farther towards the centre of circulation. the process that takes place under such circumstances, is strictly analogous to union by the first intention. the blood may coagulate and adhere to the sides of any part of the vascular system. the union thus formed may be permanent, or the coagulum may be again broken up and carried with the blood in the course of the circulation, as shown in experiment vi. when this occurs, as is shown in the same experiment, other changes supervene in remote parts of the body. this tendency to coagulate around the foreign matter once impressed upon the blood, cannot be destroyed by the coagulum being mechanically broken up, as indeed is proved by the fact already mentioned, that after one attempt at union in a vein (in consequence of the introduction of foreign matter) has failed, another attempt is made immediately farther up the vessel. under these last circumstances, we may find a vein partially obliterated at different points, leaving intervals where lymph or pus are secreted. if the purulent matter introduced is allowed to remain a short time only in the vein, no inflammation is produced (experiment vi). but when any irritating fluid is detained there in consequence of the blood coagulating around it, adhesive, ulcerative, or suppurative inflammation, will be excited (experiments vii and viii). the slowness with which veins inflame when cut, tied, or bruised, has been made a subject of comment by different authors; and mr. travers, in particular, has endeavoured to reconcile "the infrequency of its occurrence" with the rapid and violent character of the inflammation in certain cases. although, under ordinary circumstances, a wounded vein does not inflame, yet the annexed experiments show, that pus introduced into its cavity will produce inflammation, in which the system will sympathize. other fluids besides pus will no doubt produce similar effects; but those of pus are here particularly noticed, as affording a good illustration of the series of changes produced by the introduction of foreign matter into the blood. what the symptoms are which characterize the presence of pus, as distinguished from other secretions in the blood, it would probably be difficult to determine in cases as they occur in practice. the examination of the blood in these instances affords no very satisfactory information; for the characters of pus, when the blood has once coagulated round it, are so altered, that i know of no means by which a small quantity can be recognized, when it has once entered the circulation. the conclusions drawn from the different facts now stated are,--first, that inflammation of a vein, or phlebitis, is no essential part of the primary affection which precedes constitutional symptoms, even when morbid matter has found its way into the circulation through a vein. secondly, that when inflammation of a vein does occur, in some instances at least, it is not the cause, but the consequence of the introduction of diseased or foreign matter into the blood. thirdly, that although veins are with difficulty inflamed by any mechanical injury, they are susceptible of rapid inflammation, accompanied with constitutional disorder, whenever any irritating fluids are introduced into their cavities. iii. when the principal veins in a part become obstructed, it is natural to suppose that changes should be produced in the smaller veins which supply them. these changes may be expected in a more marked degree, when the obstruction depends upon coagulation of the blood, than when it arises from other causes, inasmuch as the coagulum usually extends to several veins at the same time. in the experiments that have been made upon animals, it has been a matter of surprise that, while extreme pain was evinced upon the injection of irritating fluids into the veins, comparatively little or no suffering was produced, when similar experiments were performed upon the arteries. the foreign matter introduced in these cases would probably have the effect of coagulating the blood, as in the instances already mentioned. if this occurred in an artery, the supply of blood below the obstruction would be diminished; but if in a vein, the return of blood would be prevented: in the latter case, the continued influx of blood to the part would necessarily distend the capillaries. in m. cruveilhier's[14] experiment, of injecting ink into the veins of dogs, he found, that in thirty-six hours the legs swelled, and a number of bloody patches (_foyers apoplectiques_) were found in the substance of the muscles and the cellular tissues of the limb. the large veins were distended with adherent coagula of blood, and the smaller veins around the livid patches were also filled with coagulated blood. if the animal were allowed to live, the congested spots suppurated. the appearances thus produced in the muscles and cellular tissue of the limb were evidently not those of inflammatory action propagated along the coats of the veins, for the affection in the capillaries was circumscribed, and terminated in many places abruptly, leaving the veins in the immediate neighbourhood perfectly healthy; still less could the appearance produced depend upon the injected fluid finding its way through the veins (contrary to the course of the circulation) to the capillary system; nor, lastly, could it depend upon the ink finding its way into the general circulation, and producing its effects in its course a second time through the limb; for, not to mention that the capillaries of the lungs and other parts would be equally liable to be affected, one essential condition of the success of the experiment is mentioned to have been, that the fluid injected should _not_ find its way along the vein in the usual course of the blood. we therefore conclude, that it was the coagulation of the blood in the large veins which caused the congestion of the capillaries, those veins remaining unaffected which could discharge their contents by some collateral channel. [14] cruveilhier's path. liv. xi. in cases of phlegmasia dolens after child-birth, the same principle can sometimes be traced; thus, in a dissection performed by mr. lawrence,[15] the external and common iliac veins were filled with a substance like the laminated coagulum of an aneurism. "the tube was completely obstructed by this matter, adhering as firmly as the coagulum does in any part of an old aneurismal sac. in its centre was a cavity containing about a teaspoonful of thick fluid of the consistence of pus, of a light brownish red tint, and pultaceous appearance." the femoral vein was in this case also filled with a coagulum; but, as is observed in the account of the dissection, the red colour of that vein might have been caused by the clot everywhere in contact with it, and therefore cannot be deemed a proof of inflammation. [15] medico-chirurgical transactions, vol. xii. mr. guthrie[16] has published a case of inflammation of the veins after amputation, resembling phlegmasia dolens, in which the veins of the opposite limb, even down to the foot, had become affected. in this case, on the fourteenth and fifteenth days after amputation of the right thigh, the left leg began to swell, and became intolerably painful. "the swelling was elastic, yielding to the pressure of the finger, but not in any manner like an oedematous limb. _upon a careful examination, no pain was felt in the course of the iliac vessels upon that side_; the stump looked well, save at one small point, corresponding to the termination of the femoral vein." on examination after death, the termination of the vein on the surface of the stump _was open_, and in a sloughy condition. at the left groin, the iliac vein was greatly distended with pus. sir henry halford[17] has also mentioned three cases of what he has termed phlegmasia dolens, occurring in the male, in one of which the iliac vein was found obliterated after death. in this case, the patient had suffered, for several years before his death, from swelling of the left leg and thigh. in the interior of the obliterated vessel there is a coagulum, which has lost its colour, and become firm and completely adherent to the inner surface of the vein. (see prep. no. 1732, path. mus. coll. of surgeons.) the rapid swelling and general pain of the limb in such cases, indicate a sudden obstruction to the circulation, while the absence of tenderness in the course of the vessels during the first stages of the disease, tends to show that the contents of the vessels, and not the vessels themselves, are primarily interested in its production. [16] medical and physical journal, vol. lvi. [17] london medical gazette. the foregoing remarks have appeared necessary, in order to explain a circumstance mentioned by hunter, upon which considerable stress has been laid by subsequent writers. mr. hunter observed that the whole side of the head in horses that had been bled would frequently become swollen and inflamed. the explanation of this fact appears very simple, when viewed in relation to the general principle illustrated by the above cases. the horse has only one jugular vein upon each side; and, although in the usual operation of bleeding, its channel is not obstructed, yet if the wound do not readily heal, its contents will coagulate. the circulation will then be obstructed in all the distant branches, and the blood, if long retained, will coagulate in them also. it will then part with its serum, and give rise to all the symptoms of inflammation in the distant vessels; a pulpy elastic swelling, accompanied with great pain, will then be the principal symptom, while the turgescence on the surface will be less than where the superficial veins have been mechanically compressed. it will, however, very frequently happen, that a vein in a part may be felt distended without any symptom of inflammation being present; and, in other cases, the pain and swelling will appear and disappear too rapidly to allow the idea that they depend upon inflammation of the coats of the vein. it has occurred to the author, to feel a vein in the arm and hand distended during life, and after death, to find it empty, and its coats of their natural colour and thickness; in such a case, the coagulum gives way, becomes broken up, and mixed with the circulating blood. iv. when pus, or other diseased fluid, is confined to the cavity of a vein, the constitutional symptoms produced are comparatively mild, as long as it remains limited and circumscribed by adherent coagula; that is to say, so as to be excluded from the rest of the circulating system. (compare the frequency of the respiration in experiments vi and vii.) but the tendency of a clot of blood is to contract; and a time comes when the coagulum is either broken up, or shrinks, so that if no further changes are produced, the current of blood through the vein is re-established.[18] meanwhile, however, the coats of the veins have undergone changes corresponding to the degree of irritation produced by the contained fluids, and the intention or result to which the inflammation tends. if the coagula have long remained, the coats of the veins are always found thickened, sometimes to three or four times their natural thickness, and sometimes so as to completely obliterate the vessels. the contents of the veins are occasionally found to consist, as far as can be seen, simply of coagulated blood; at other times, they are found filled with soft yellowish coagula, deprived, more or less perfectly, of their colouring matter; more rarely, the cavity of a vein will be found filled with dark-coloured membranous layers, leaving still a channel through the vessel; and occasionally it will be found completely obstructed by "dense, dark-coloured, bluish membranes." [18] this remark i have had opportunities of verifying in cases, where needles have been introduced under varicose veins in the lower extremities, and allowed to remain, with a ligature around them, for ten days or a fortnight. the circulation through the vein will in such cases be obstructed; but, in a year or two, will be found to have become completely re-established. as the coagulum contracts in a vein, if the intention is to obliterate the vessel, its sides are gradually approximated. in the smaller veins, and in the divided extremities of large veins, the sides are soon completely drawn together. but the latter, if not wounded, may for a long time (see prep. 1732, path. mus., coll. of surg.) retain coagulated blood in their contracted, but not completely closed, cavities. in both cases, the coagula which close the veins are liable to be displaced by accident, or to have their adhesions loosened by the changes which they undergo. the position of a vein, and the structure of the organ through which it passes, may be unfavourable to its healthy reparation. the process of repair goes on frequently during a continued flow of blood over the part, and sometimes during the constant action of the muscles in the neighbourhood: at other times, an injured vein will be situated immediately in the bend of a joint, and will be subject to be continually bent and extended with the motions of the limb. in the structure of the bones, the veins lie in unyielding channels, and are consequently deprived of the assistance derived from the approximation of their sides, as in soft parts, during the process of reparation. as the coagula contract in such a case, there is danger lest the union by the first intention should be disturbed, and that the cavities of the injured veins should be left exposed. again, in the uncontracted uterus after child-birth, the veins which open upon the placental surface, pass through the firm texture of the organ, and are incapable of contraction independently of the muscular structure which surrounds them. the coagula which close their extremities secure them against the entrance of any foreign matter; but should these coagula be removed before the vessels are otherwise protected, their open mouths are exposed to any secretions that the uterus may happen to contain. in these cases, if a coagulum is not firmly formed, or if it is displaced by violence, it may be broken up, and portions of it mixed with the fluid blood. subsequent coagula may form in the veins and offer fresh obstructions to the admission of any foreign matter, but these may, as in the first instance, be disturbed, and carried, together with any admixture of the secretions of the part, in the course of the circulation. the period at which the union of a coagulum in a vein is dissolved, is sometimes marked with great precision. in a case recorded by dr. davis,[19] a patient was convalescent from an attack of phlegmasia dolens, when death took place instantaneously, while the patient was in the act of changing the sitting for the recumbent posture; the left external iliac vein was thickened, and its internal tunic was studded in several places with deposits of adherent lymph. the portion most remarkable for this incrustation, as well as for other disease, was immediately beneath poupart's ligament; the vein, although contracted, was _manifestly pervious_. [19] medico-chirurgical transactions, vol. xii. v. it has been shown in the previous sections, that secretions mixed with the blood will alter its properties, and influence the period of its coagulation: that when the blood is thus altered, it may pass through a vessel without leaving any trace of its passage; but that if it coagulates and remains in a vein, the coats of the vessel will then take on increased action. the exciting cause of the inflammation in such cases appears to be conveyed by means of the contents of the vessels to the vessels themselves. but, as in post-mortem examinations, the changes produced in the vessels are much more easily recognized than the alterations in their contents, the former have of late years almost exclusively occupied the attention of pathologists. the cases in which constitutional symptoms follow inflammation of the veins, will be found to divide themselves principally into three large classes. 1. those in which one of the larger veins has been opened. 2. those in which some portion of bone has been involved in the original lesion. 3. those that occur after child-birth. in each of these three classes of cases, a free communication will be found to exist between the injured part and the general circulation. the natural mode of sealing this communication, when it is no longer proper, is the coagulation of the blood in the veins of the injured part. when, from some constitutional affection, or from some local peculiarity of structure, this intention is not fulfilled, a ready passage remains open, through which the blood may become infected. when pus has been injected into the veins, it has frequently happened, that no great constitutional disturbance, and no signs of secondary inflammation, have been produced; but this is believed to have depended upon the coagula in the veins having prevented (as probably occurred in experiments vii and viii) the foreign matter from finding its way along the vessels. but if this obstruction be not offered, or be overcome, then the appearance of secondary inflammation, accompanied by corresponding constitutional symptoms, will be produced. if water be injected into the cancellous structure of bone, it will find its way out in drops through the apertures of the nutritious vessels. the ready communication which is thus shown to exist between the interior of bones and the veins, has been but too often exemplified by m. cruveilhier's experiments of introducing mercury into their cancellous structure, and finding it subsequently in the vascular system. this fact assumes peculiar significance, when taken in conjunction with the very large proportion of cases, in which some portions of bone will be found to have been involved in the primary lesion, in those who have died of secondary inflammations. of fifty-two consecutive cases, occurring in surgical hospital practice, of which i have preserved notes, in no less than forty-one was some portion of the osseous system implicated. again, in the third class of cases above-mentioned, if the vena cava be injected after parturition, the injection will very speedily find its way into the uterus.[20] the ready communication which is thus shown to exist between the vascular system and the local affection, in each of the three large classes of cases which usually give rise to subsequent disease, would of itself afford at least a very remarkable coincidence. but more direct evidence presents itself of the way in which the system becomes contaminated in these affections: thus, after an operation for hæmorrhoidal tumours, an effusion of lymph and pus has been found in the hæmorrhoidal veins,[21] from thence the same appearances have been traced to the inferior mesenteric vein, and the severity of the secondary affection, indicated both by the symptoms and the post-mortem appearances, has fallen upon the liver. these circumstances all tend to point to the venous system as the means by which morbid matter in such instances is introduced: and the still more conclusive facts afforded in the production of secondary disease, by injecting fluids into the veins,[22] allow scarcely a doubt to remain upon the mind, that the unprotected veins are the channels, in a very large proportion of cases, through which the blood becomes infected. [20] dance. archives générales de méd. vol. xviii, p. 480, dec. 1828. [21] in cases where pus has been found in veins surrounded by coagula, its presence and detention there have been differently accounted for. m. cruveilhier appears to have imagined that the loose coagula act as filters, through which the blood passes, while the pus is retained. (_dict. de méd. et de chir._ t. xii, p. 641.) the true explanation of the way in which coagula form round pus in the veins has already been given. [22] see m. gaspard's experiments. vi. the cancellous structure of bone may be compared to the cellular tissue in soft parts. when inflamed, its intervals become filled up by effusion from the vessels, and an abscess may be as accurately circumscribed in the hard as in the soft structures of the body. in a healthy constitution, the adhesive inflammation will, in this way, always precede the suppurative; but where the inflammation is not circumscribed by adhesion, the secretions may permeate from cell to cell in unadhering parts. in soft structures, a remedy is at hand for allowing the escape of the matter, by a free division of the parts; but in bone, where the same thing takes place, the hard unyielding sides offer an effectual obstruction to the escape of any effused fluid. the cells of the bone then may become infiltrated, and, unless the veins of the part have been closed, there is nothing to prevent the diseased secretions from finding their way into the circulation. m. cruveilhier assures us, that a single drop of mercury introduced into the cancellous structure of living bone, may subsequently be detected in the capillaries of the lung, where it becomes the centre of one or more patches of livid congestion. this experiment appears to afford a perfect illustration of the way in which diseased secretion may be conveyed into the circulation, when the natural processes of repair in bone are abortive. these processes are the same in bone as in the other structures of the body; viz., union by the first intention, and adhesive inflammation. in soft parts, as the fibrin, which forms the bond of union in the first of these, is absorbed, the divided veins collapse, and thus continue closed; but in bony structures, where the injured vessels are held open, as the fibrin which at first closed their extremities becomes removed, their channels may be left as much open to the diseased secretions of the part, as to the globule of mercury in m. cruveilhier's experiment. the low degree of organization in bone, and the comparative slowness with which actions are there carried on, render it, in a peculiar degree, liable to interruptions in the process of repair; especially when, as not unfrequently happens, there is reason to believe that the vitality of some portion of the bone has been threatened. the offensive smell of the bone, as well as the appearance of its cancellous structure infiltrated with puriform matter, will frequently show in such cases, that the processes above-named have not followed their natural course. vii. as a necessary deduction from the accompanying experiments, and those of m. cruveilhier, alluded to in the previous section, we arrive at the conclusion, that a vitiated condition of the blood may give rise to inflammation of the veins in different parts of the body. the circumstances which occasionally attend reparation of the uterine veins after child-birth, will be found to lead to the same inference; and the same general proposition will derive fresh support from the consideration of this class of cases. the veins which terminate upon the placental surface of the uterus are necessarily open when this organ is distended, and become more or less perfectly closed when it contracts. in cases when the contraction is incomplete, innumerable open-mouthed orifices are left bathed in secretions, which are often offensive and undergoing decomposition; the natural protection to the vessels then, is the coagulation of the blood in them. if examined, the uterine veins will be found filled with coagula for some distance. but in cases where this power is impaired, all the uterine veins and arteries recently separated from the placenta may be found bathed in the secretions of the part, under circumstances most favourable for their absorption. the passage of diseased secretions through the vessels cannot always be traced in this, any more than in the other forms of the disease. many of the substances introduced artificially into the circulation by m. gaspard, produced no action upon the coats of the veins through which they passed, and yet the general symptoms were precisely similar to those originating from genuine phlebitis. in accordance with this, it may be observed that the uterine veins are often found perfectly healthy when the spermatic, or renal, or still more distant veins are thoroughly disorganized. in either case, the healthy condition of the veins near the original lesion forbids the idea of inflammation having been propagated along the coats of the vessels, while all analogy appears in favour of the disease being transmitted through their contents. in a certain number of cases no lesion will be found in any of the veins of the body, but the uterine veins will be found to contain some unnatural fluid; at other times coagula of blood, which have lost their elasticity, gritty to the feel, and greyish or light brown in appearance, will be found filling the veins or leaving intervals in them, where lymph or pus may be recognized. it matters little whether the unnatural fluids, thus found in the uterine vessels, have been absorbed from the cavity of the uterus, or are the product of venous inflammation. the effect upon the blood in either case would be the same. when obstructions form in the spermatic veins, they are not indicated by any external symptoms; but when the veins opening into the internal iliac are similarly affected, the coagula are liable to extend into its cavity, and even beyond it to the external and common iliac vessels. the free return of the blood from the inferior extremity, will then be prevented. the effects of this have already been described (sec. iii.) the connection of this form of disease with affections in distant parts of the body, has been noticed by several eminent writers. legallois has expressed his conviction, that phlegmasia dolens, puerperal fever, and many other puerperal ailments, are solely dependent upon the absorption of pus from the uterine surface. this opinion appears to have been formed upon too hasty a generalization, inasmuch as other fluids besides pus, as evinced by some of the annexed experiments, may produce similar effects upon the blood. but that pus, when absorbed, will determine the coagulation of the blood in the iliac as well as in other veins, must be allowed; and that the symptoms of obstructed venous circulation arising from this cause, will exactly resemble those of phlegmasia dolens, will scarcely be denied. "besides depositions of pus in certain portions of the frame," observes dr. ferguson, "i have seen two other states of the limb, which are connected with and traceable to the cause originating puerperal fever. in one of these the malady looks like erysipelas...; in the other, the leg is attacked with a disease so exactly resembling phlegmasia dolens, as to leave no doubt in my mind that they are one and the same malady. in this, as in other forms of the disease, there may be a tendency to gangrene of the skin." the period of the occurrence of what has been described under the name of uterine phlebitis is marked with much precision, and the affection of the system is often general and sudden. it may be stated as the result of all the observations hitherto made, that it occurs most frequently from the 10th to the 20th day after parturition.[23] if the inflammation in such cases were propagated along the vessel only, it would be difficult to account for such an apparently capricious selection of time for its development. this difficulty, however, disappears when the period is observed to be so strictly in accordance with the time at which the same symptoms occur after other local complaints, and to be, moreover, the time at which the coagula formed in the veins, may naturally be expected to shrink. [23] dr. lee. medico-chirurgical transactions. it has been observed, that inflammation after child-birth usually attacks the spermatic veins alone, and for the most part the one only on that side of the uterus to which the placenta has been attached. the hypogastric veins are comparatively rarely affected. the appearances observed upon dissection in the spermatic vein, usually terminate abruptly at its opening into the vena cava on the right side, or into the renal on the left. this fact is in perfect accordance with that observed by mr. arnott, that the coagulum in veins extends usually only to the nearest collateral branch; the explanation appears to be the same in both cases, as illustrated by experiment vi. if the coagulating blood be left undisturbed, it will form adhesions to the sides of the vessel and produce increased action in its coats; but if mechanically disturbed, it will be carried forward before the process of coagulation is completed, and leave the vein in its natural condition. when any portion of a vein is obstructed, the blood is kept at rest between the obstruction and the next collateral branch; and, if disposed to coagulate, there is nothing to interfere with such an action. but the case is different, as soon as one vein opens into another. a fresh current of blood is then continually sweeping the orifice of the obstructed vessel; and, even although the blood at this point should have a tendency to coagulate, it is carried on in the course of the circulation, before it can adhere to the sides of the unobstructed vein. the sudden termination of the diseased appearances in these cases, affords an additional proof that the blood is the medium by means of which this affection is transmitted. it is true, in such instances the diseased fluid cannot be always, or even generally, traced in the veins, and very many cases occur where a retained and putrid placenta, or decomposing coagula, remain in contact with the mouths of the uterine veins, without any of the symptoms of local phlebitis being produced; but this is only in accordance with what is observed in cases where purulent or other fluids have been directly injected into the blood. the examination of the blood, or of the vessels, in such cases, will by no means invariably indicate the presence of foreign matter after it has once become thoroughly mixed with the blood, nor will inflammation of the vein through which the fluid passes, be by any means invariably produced. when a foreign substance is introduced into an artery, any immediate effects upon the blood may naturally be looked for in the system of capillaries which it supplies. if the blood then coagulates, local symptoms alone, will, in the first instance, be produced, and the constitution will remain unaffected. m. magendie,[24] indeed, asserts that fluids injected into the arteries of animals, return quickly through the corresponding veins, and that this takes place even more rapidly in the living than in the dead body. if this were universally true, it would matter little whether foreign matter were introduced into the arterial or venous system. the effect upon the constitution would be the same in either case. but if, as is now maintained, extraneous matter introduced into the blood may, under certain circumstances, produce its coagulation, then the effects will be confined, more or less completely, to the first system of capillaries which the blood meets with in the natural course of its circulation, and the constitution will be affected only in consequence of the changes which then take place. m. gaspard has shown that greasy fluids, and such as contain sediments, do not find their way readily from the small arteries into the veins. they become entangled in the intermediate capillaries, and there produce, first patches of local congestion, and subsequently serous effusion and abscesses. some clear fluids, on the other hand, such as solutions of tartar emetic, of opium, and of nux vomica, when introduced into an artery, pass readily in the course of the circulation, and produce their full effect upon the constitution; and in such cases no irritation is manifested in the capillaries through which they pass. the first of these poisons produces vomiting and purging, the second stupor, and the third tetanic rigidity, exactly in the same manner as if they had been introduced into the stomach, or injected into a vein. [24] précis elémentaire de physiologie, t. ii, p. 389. there are yet another class of substances differing in their effects from both of the former; and under this head are classed infusion of tobacco, solution of acetate of lead, putrid fluids, etc. these are distinguished from the first class above mentioned, as not offering in themselves any mechanical impediment to the circulation of the blood, and from the second, as not producing the same constitutional symptoms when injected into an artery as when thrown into a vein. m. gaspard found that, when introduced into an artery, the infusion of tobacco neither produced vomiting nor stupor, the solution of acetate of lead did not act upon the intestines, and the putrid fluids did not produce the evacuations usually observed after their introduction into the system by other means. all these substances, however, were found to produce violent local irritation in the parts to which the branches of the injected artery were distributed, and the constitutional symptoms were those produced in consequence of the local irritation, and not those which would arise directly from the action of those poisons upon the system. in experiment xx, seven or eight cubic inches of common air were gradually injected into the carotid artery of a dog, and half an hour afterwards an ounce of water, to which seventy drops of medicinal prussic acid had been added, was thrown into the same vessel; none of the peculiar effects of the poison followed this operation. at the expiration of another quarter of an hour, an ounce of a saturated solution of nux vomica was likewise injected, still without producing any constitutional symptoms. it is very remarkable in this experiment, that m. gaspard[25] should have considered that the elasticity of the air contained in the vessels was sufficient to counteract the impetus of the blood, and thus to prevent the progress of the poison along the vessels, especially when we find him stating that, on a post-mortem examination, the smaller vessels appeared to have been _obstructed by very hard clots of blood_. [25] journal de physiologie, t. v, p. 328 and 336. experiment i. (_a_). on the 25th of september, 1848, having procured four small vessels of equal sizes, i placed in the first some dilute sulphuric acid, in the second some offensive pus, and in the third some water. the fourth vessel was left empty. they were then all equally warmed, and some blood from the jugular vein of a healthy horse was received into each of them so as to fill them to the same level. they were now stirred with separate pieces of wood. at the expiration of two minutes (noted by a watch), the contents of the second vessel had become coagulated into one uniform mass. the contents of the first vessel (containing the acid) were thickened and of a dark brown colour; in the third and fourth cups the blood was of its natural fluidity, but darker coloured in the cup containing water than in the other. at the expiration of ten minutes, the blood contained in the fourth cup had begun to coagulate; the blood and water still remained fluid. at the expiration of a quarter of an hour, the blood had completely coagulated in the fourth cup, containing blood alone; and had very partially coagulated in the third cup containing the blood and water. (_b_). four vessels were taken, each capable of holding three fluid ounces. in the first was placed half an ounce of cold water, in the second half an ounce of dilute sulphuric acid, and in the third half a drachm of pus, which was quite fresh and sweet. all the vessels were then quickly filled with blood, from the jugular vein of a horse. the contents of each vessel were stirred. the blood and dilute sulphuric acid became thick, and changed in colour almost immediately, as in the first experiment, but did not coagulate. the pus and blood coagulated in six minutes, and the mass was firm in seven. the pure blood coagulated in twelve minutes and was firm in sixteen. the blood and water coagulated in about the same time, but took nineteen minutes to become firm. the above and the following experiments were made at the suggestion of the author, in conjunction with mr. t. w. mayer,[26] veterinary surgeon. [26] the present mayor of newcastle-under-lyme. experiment ii. an abscess was opened in the groin and a quantity of pus received into a gallipot; some blood from the divided vessels was also received into the same vessel; they were then stirred together, and in two minutes the mass coagulated. some blood taken from the same patient in the same manner, but not mixed with pus, coagulated in eleven and a half minutes. experiment iii. on the 20th of january, 1849, an inflamed and suppurating abscess was opened, and the blood and pus which flowed from it were mixed together. they coagulated in two minutes and twenty seconds. this experiment was repeated several times, with nearly similar results. experiment iv. in june 1849, a tense inflamed swelling was opened in the perinæum of a patient, who had for years laboured under a very obstinate stricture. a quantity of matter first escaped, and subsequently serum, mixed with shreds of lymph and small quantities of pus and blood, continued to flow for some time. portions of this mixed fluid were received into separate vessels; they coagulated on an average in about two minutes. experiment v. two ounces and six drachms of blood were taken from a healthy horse, and two drachms of pus were mixed with it. the mass coagulated in three minutes and three-quarters. experiment vi. a healthy male ass, three years old, was procured, and, with the assistance of mr. mayer, was made the subject of the following experiment, on the 23rd of september, 1848. three drachms of pus were collected from an issue in the chest of a horse, which laboured under inflammation of the lungs. the pus thus obtained was quite pure and sweet, and having been warmed, was injected, by means of a syringe, into the left brachial vein of the ass. the animal lay quiet, till nearly the whole of the pus was injected; it then struggled, and a small quantity of the pus may have been lost. when the operation was completed, the sides of the vein were brought together with a pin, and the animal was allowed to get up. the vein above the opening could now be felt as a hard, unyielding cord, as high as it could be traced with the hand; but upon gentle pressure being made, so as to propel the blood in the course of the circulation, the hardness completely disappeared. the vein which, immediately after the operation, was hard and prominent, no longer presented anything remarkable to the touch. the animal now moved from side to side, as if inclined to lie down. two hours and a half after the operation, the pulse, which naturally was 36, had risen to 60; and the respiration from 12 per minute had increased to 26. _september 24th._ pulse 52; respiration 20; mouth hot; ears cold. in the evening the pulse became 48 and the respiration 16; he coughed occasionally. _25th._ pulse 48; respiration 12; some dullness of countenance, but he is lively and occasionally playful. the left fore-leg is swollen; the ears are very cold. in the afternoon he was killed, and the blood was allowed to flow from the body. _post-mortem appearances._ the wound in the left leg opened directly into the brachial vein, which was filled with lymph and a thin pus for a very short distance, both above and below the external opening; immediately above this, the vein was healthy, nor was there any appearance of disease in any of the other veins of the limb, nor in the veins leading to the heart. the glands in the axilla were swollen. the lungs were found studded irregularly in different parts, with circumscribed spots of livid congestion: these existed both upon the surface and in the substance of the lungs; they were generally about the size of a filbert, but in some places they occupied a single lobule, and were accurately circumscribed by its outline. experiment vii. on the 23rd of november, 1848, about an ounce of perfectly pure pus (previously warmed) was injected into the right jugular vein of an aged ass; the vein immediately became "corded", and the blood appeared to have coagulated in the vessel. the operation did not much excite the breathing; but the pulse, which naturally was 35 in the minute, rose to 60, and subsequently fell to 55. _24th._ the animal dejected; appetite indifferent. the vein can be traced as a thickened cord as far as the sternum. respiration 12 (the natural standard); pulse 50. _25th._ the parts around the vein much infiltrated with serum: pulse 55; respiration 12. _26th._ the wound in the neck began to suppurate, and an abscess subsequently formed in the course of the vein, about midway between the opening and the sternum. the general symptoms continued, with very slight variation, until the 4th of december, when the animal was destroyed. _post-mortem appearances._ the jugular vein was found to have become inflamed only in the course of the circulation, and to be obliterated a short distance below the external opening. the surrounding parts were greatly infiltrated with serum and lymph, and several abscesses had formed in the immediate neighbourhood. the lungs did not present any well-defined patches of congestion, as in the last mentioned experiment. experiment viii. a healthy ass, six years old, was operated on upon the 16th of november, 1848. the respiration was naturally 14 in the minute, and the pulse 38. about two ounces of highly offensive pus, obtained from the frontal sinus of a horse, were injected into the left jugular vein; the pus had unintentionally been mixed with water previous to its being injected. the vein became full during the operation, as though the blood in it were in a semi-coagulated state. the pulse now became 60, and the respiration 20 in a minute; slight rigors occurred in two hours. _november 17th._ the animal is tranquil; appetite good; pulse 48, small and wiry; respiration 16. in the evening he was rather more excited; the vein was becoming inflamed downwards towards the heart; pulse 60; respiration 20. _november 18th._ the vein was more inflamed, and slight suppuration was visible at the orifice of the wound. respiration 16; pulse 55. from this period to the 23rd, the pulse continued from 55 to 60, and the respiration varied from 12 to 18. _november 26th._ the swelling in the situation of the vein is rapidly subsiding; pulse 55; respiration 12. the animal gradually recovered, and on the 26th of february, 1849, was made the subject of another experiment. the right jugular vein having been opened, two fluid ounces of pure healthy pus were injected, and propelled in the course of the circulation, by pressure upon the vein externally. the vein became tense during the operation, and sensibly resisted the attempts that were made to propel its contents towards the heart. _even forcible pressure was not sufficient to overcome the resistance offered to the return of blood._ soon after the operation, the animal had a rigor; the breathing became laborious, but not accelerated; pulse 57. after the lapse of seven hours, the animal appeared dejected; he refused to eat or drink; the extremities were cold; breathing 16 in the minute; pulse 60, small and irregular. _february 27th._ the vein can be felt thickened as far as the sternum. the general symptoms are the same as on the previous evening. _28th._ there appears less constitutional irritation; pulse 60; respiration 14. _march 2nd._ appetite still indifferent; pulse 60; respiration 16. from this date to the 7th, when the animal was destroyed, the general symptoms continued much the same, but the induration and swelling around the jugular vein, from the opening to the sternum, became greater. _post-mortem appearances._ the left jugular vein was found completely obliterated. the remains of a firm coagulum obstructed its canal for some distance below the opening which had been made into it, and terminated, below, in an elongated conical portion, which adhered to one side only of the vessel. on the right side, an abscess had formed in the course of the vein; and for two inches, the whole of the parts were imbedded in a confused mass of pus and lymph, in which it was impossible to distinguish the structure of the vein. both above and below this, for several inches, the vein was filled with coagula, which effectually obliterated it. these coagula extended for several inches in the course of the circulation; but beyond them, in both directions, the vessel was pervious. the lungs presented some slight spots of congestion, but not of the same characteristic kind observed in experiment vi. the other organs were healthy. experiment ix.[27] [27] this, and the following experiments, are among those recorded by m. gaspard, referred to in the foregoing dissertation. two drachms of pus, somewhat fetid, derived from a large common ulcer, and diluted with a little water, were injected into the jugular vein of a middling-sized dog. the animal immediately made several convulsive efforts to swallow, and soon became faint. it showed indications of pain, and vomited more than six times in the course of the day. at the expiration of an hour, it appeared slightly relieved by an evacuation, and by passing turbid urine. in the evening, it was very ill; it lay upon its side with its legs extended; had a very feeble pulse and scarcely perceptible respiration. ten hours after the experiment, it passed black, liquid, and extremely offensive motions; these were accompanied by immediate relief. the animal regained its appetite, eat and drank freely, and went to sleep. the day following, it appeared nearly well. on the third day, three drachms of the same pus were injected into the opposite vein; after the lapse of a certain time, there occurred, as in the first instance, faintness, vomiting, and frequent desire to pass urine; twelve hours after the injection, frequent liquid, white, and very fetid motions were passed, and the animal died at the expiration of twenty-four hours. on opening the body, no alteration was found either in the intestines or other organs. experiment x. the last experiment was repeated on a greyhound with the same results: faintness, fever, vomiting, and repeated evacuations succeeded each other, with recovery after the first experiment, but not after the second. on opening the body, no lesion was observed, except that the inferior lobes of the lungs were gorged and almost hepatized. experiment xi. three drachms of recent pus, derived from the same patient as in the last experiments, were injected into the jugular vein of a small emaciated unhealthy dog. after the expiration of three minutes, there was an abundant evacuation of urine, followed by continued vomiting, and repeated ineffectual efforts to pass fæces. for nearly a quarter of an hour, there was a kind of emprosthotonos, rigidity of the limbs, and a death-like condition. subsequently, fresh vomiting ensued, with very fetid liquid evacuations, which were followed by apparent relief; soon after, however, long continued tenesmus made its appearance, and terminated in death, five hours after the injection of the pus. on opening the body, the mucous membrane of the intestines was found red, swollen, and inflamed, especially in the colon and rectum. experiment xii. half an ounce of pus, similar to that used in the preceding instances, but more putrid, in consequence of having been longer kept, was introduced into the veins of a middling sized dog. the animal, as in the other cases, was seized with vomiting, accompanied by violent straining. subsequently, strongly marked nervous symptoms made their appearance. the eyes wandered; there was extreme sensibility, and involuntary convulsive twitching over the whole body, accompanied by faintness, hiccough, and short piteous cries. the walk was unsteady, staggering, and without apparent object. there was furious delirium, ardent thirst, dyspnoea, palpitation of the heart, etc. this state lasted for nearly two hours, and the animal died in frightful convulsions, without having experienced any critical evacuations, as in the former cases. _post-mortem appearances._ on opening the body, while still warm, the venous blood was found very firmly coagulated, not parting with any of its serum when left at rest; the left ventricle of the heart showed, on its external surface, some stains of the colour of lees of wine, formed by a kind of concrete pellicle, which disappeared only after long rubbing and maceration. the other organs appeared healthy. experiment xiii. some beef was allowed to decompose in some dog's blood; half an ounce of the fluid resulting from the decomposition, was injected into the jugular vein of a little bitch. immediately, the animal made several convulsive efforts to swallow, and soon became oppressed, uneasy, and faint. at the expiration of an hour, there was great prostration, accompanied by repeated gelatinous and bloody evacuations, and vomiting of bilious matter. the strength became gradually less, and the animal died three hours after the injection. _post-mortem appearances._ the lungs were found inflamed in a very peculiar manner. they were gorged with blood, of a violet or black colour, and presented many petechial spots, like small ecchymoses. these spots existed also on the left ventricle of the heart, in the spleen, in the mesenteric glands, in the gall-bladder, and even in the subcutaneous cellular tissue. the peritoneum contained some spoonsful of a reddish serum; but the mucous membrane of the digestive organs was found to have been principally affected. in the stomach it was slightly inflamed. in the intestines, but especially in the duodenum and rectum, it was of a livid colour, presenting many black spots, and covered by a gelatinous and bloody secretion, resembling lees of wine. the tissues in these parts were slightly thickened. experiment xiv. the preceding experiment was repeated, by injecting into the jugular vein of a moderately large dog, an ounce of fluid, derived from the maceration of putrid beef in water. the animal very soon passed extremely offensive, liquid evacuations, with much urine. the breathing became quick and deep, the pulse small and quick. repeated efforts were made to empty the bowels. there was great depression and want of strength. at the expiration of an hour, a kind of diarrhoea or dysentery made its appearance. liquid, bloody, and fetid evacuations, continued for an hour and a half, when the animal died. _post-mortem appearances._ livid, brown, and black patches were found scattered over the lungs. the intestinal canal was filled with a bloody mucous secretion, resembling the matter that had been voided; its mucous membrane was of a livid colour, as in the preceding case. experiment xv. two ounces and a half of thick fetid fluid, derived from the maceration of cabbage leaves in an equal quantity of water, for two days, at a temperature of 77 fah., were injected into the right jugular vein of a moderate sized dog. during the operation, the animal made several efforts to swallow, and soon became faint, and vomited several times. some hours afterwards, there was great uneasiness and oppression, with recurrence of the vomiting, and continued faintness during the day. after nine hours, a most copious and very fetid evacuation took place. the discharge was as black as soot, and composed of mucus, with a little fæcal matter, and a large quantity of what appeared to be corrupted blood. some time afterwards, there was a second evacuation of bloody mucus, exactly resembling the first. on the following day, there was much loss of strength: the animal lay upon its side, or staggered as it walked. there was great and insatiable thirst, with a small feverish pulse. but the most remarkable symptom was the occurrence, at intervals, of palpitation of the heart, accompanied by extraordinary force and sound, resembling that produced by long continued hypertrophy of that organ, in consequence of aneurism[28] of one of the large arteries. on the third and fourth days, the animal was better, but there were still great thirst, fever, and occasional rejection of fluids from the stomach. on the fifth day, the symptoms became aggravated; there was extreme weakness, a tottering gait, excessive thirst, the eyes red and filled with gum; the nostrils were stuffed, swollen, and obstructed with mucus; and the lining membrane of the mouth was tumid, and of a violet red colour. in the middle of the day, there was a liquid greyish white evacuation, resembling pus in its odour, consistence, and appearance, mixed with some clots of putrified blood. death occurred during the following night. [28] i once observed a similar condition in a young woman in st. george's hospital. each pulsation of the heart could be heard with great distinctness at a distance of two or three yards from the patient; during the paroxysms, there was the greatest difficulty of breathing; the countenance became anxious and livid, and a distinct thrill was communicated to all the arteries. after death, the countenance and upper part of the body were found livid from venous congestion. the lungs did not readily collapse when the chest was opened. the auricles of the heart were greatly distended with black blood; the inner surface of the left ventricle presented a white patch, of about two square inches in extent; the lining membrane of the aorta, for several inches, was of a bright red colour; this extended round one-third only of the circumference of the vessel. no other structural change could be found in the heart or vessels, which would account for the symptoms observed during life. _post-mortem appearances._ the mucous membrane of the eyes, nose, and mouth, was red or violet, and covered by a very abundant thick mucus. the lungs were of a dark colour, with some black patches, but still crepitant. the left ventricle of the heart presented several brown stains, resembling ecchymoses, which penetrated into its tissue. its internal surface was of the colour of lees of wine, offering a singular contrast to that of the right side, which, however, contained a hard fibrinous concretion, two drachms and a half in weight, of a light yellow colour, and resembling grease in appearance. this was of the same consistence throughout, everywhere free, with the exception of a portion of the size of a finger nail, which adhered to an irregular and apparently inflamed spot on the inner surface of the ventricle; no appearance of the injected fluid could be recognized in this clot. it was continued of the same colour and consistence into the pulmonary artery, and into the vena cava, the vena azygos, the axillary, and even the right jugular vein. the intestinal mucous membrane, especially in the rectum, the duodenum, and a small portion of the small intestines, was of a violet red colour. it was inflamed in longitudinal stripes and in patches, which gave a mottled appearance, even to the outer surface of the intestines, before they were opened. this discolouration was not accompanied by any thickening of the tissues, nor by ulceration, and appeared rather the result of ecchymosis or hæmorrhage. the lining membrane of the rectum was principally affected, and its mucous glands were swollen and very prominent. this intestine contained puriform fluid, resembling the matter evacuated before death. the other intestines contained a very thick greyish white mucus. the mesenteric glands were inflamed, and appeared as if infiltrated with blood. the gall bladder was mottled on its surface by brown and violet patches, and contained black, thick, ropy bile, resembling melted tar. experiments xvi and xvii. _shewing the effects of the introduction of mercury into an artery._ an ounce and a half of mercury, mixed with water, was injected into the left carotid artery of a sheep. the animal immediately evinced pain, and stood immoveable upon its feet. the head was held down, there was stupor and heaviness, and the eyes were protruded and widely open. the fore legs subsequently became bent, and the head inclined over the right shoulder with a kind of convulsive rigidity, which continued till death. two hours afterwards, the animal became comatose, with some convulsive motions of the limbs, and the left eye became red and inflamed. death took place fifty hours after the operation. _post-mortem appearances._ the left eye was found in a state of suppuration, and contained mercury. many of the branches of the left carotid artery also contained some mercury, which had not penetrated to the capillary system. all the organs supplied with these vessels were red, swollen, and inflamed, in consequence of the presence of the foreign matter. the thyroid gland, the tongue, the cheeks, and the lips, were, however, only affected as far as the median line, leaving the opposite halves pale and in their natural condition. a drachm and a half of mercury, mixed with some warm water, was injected into the crural artery of a large dog. the animal evinced no pain, and walked resting slightly on the affected limb, which became sensibly colder. after the expiration of an hour, the animal refused its food, became restless, and indicated severe pain in the limb, which was now very hot. on the following day, the leg was swollen and oedematous. on the third day, there was extreme thirst, increased oedema, and great suffering. the animal was killed sixty hours after the operation. _post-mortem appearances._ no disease was found in any organ, excepting the affected limb. this was swollen and oedematous in every part; abscesses of different sizes had formed, which contained sanious fluid, mercury, and pus; some parts were in an incipient state of mortification, and gave out a considerable quantity of air. globules of mercury were found in different parts, occupying usually the centre of the abscesses, and ran out upon the scalpel when incisions were made into the limb. experiment xviii. _shewing the effect of the injection of oil into an artery._ three drachms of olive oil were thrown into the crural artery of a large dog. slight pain was experienced, and the limb became evidently cold, and the pulse under the tendo-achillis could no longer be felt. two hours afterwards, a like quantity of oil was again injected. the leg now began to inflame, and became tender. the following day, the whole limb was oedematous, much swollen, and very painful. twenty-nine hours after the first experiment, the muscles of the thigh and leg, as well as the cellular tissue, were found in some places gorged with blood, and inflamed in livid patches; in others, infiltrated with yellow serum and gelatinous exudations. no oil could be detected in the affected parts. experiment xix. an ounce of putrid water, in which some beef had been macerated, was injected into the crural artery of a middling-sized dog. the artery having been tied, the pulse ceased below the tendo-achillis; the limb, however, preserved its usual degree of heat, offering a contrast in this respect to the last experiment. a considerable degree of fever and restlessness followed the operation; this continued the whole day and the following night, without any vomiting or evacuations, which so constantly followed similar operations upon the veins. the next day the limb was very painful, but not swollen; there was thirst, with the ordinary secretion of fæces and urine. on the third day, the animal was evidently better; the appetite had become almost natural, and he could walk more easily, although the limb was still very painful. in the night, there were some soft, almost liquid, evacuations. the fourth day, the animal was evidently recovering, when an ounce and a half of very fetid and very concentrated fluid (derived from the maceration of beef), was injected into the crural artery of the opposite limb. the animal immediately evinced pain, accompanied by very violent and remarkable palpitation of the heart. it walked lame, keeping the leg raised, and soon became feverish and uneasy. the symptoms were exactly the same as after the first experiment. the leg became gradually more and more painful, extremely sensitive, but not infiltrated with serum. during the night, there was much expression of pain, and the animal was in continual motion. death occurred nineteen hours after the second injection. the limb had become swollen only within five or six hours previous to death. _post-mortem appearances._ the limb presented a very large quantity of bloody fluid infiltrated in all the tissues. the superficial muscles were black, and presented more or less the appearances of gangrene. the deep muscles existed as such no longer, but were entirely disorganized, and converted into a putrid pulp, resembling masses of the red lees of wine, extremely fetid, and disengaging a quantity of gas. the limb first injected was still swollen, and presented, in the interior of the adductor muscles, two or three cavities filled with a putrid bloody serum. in the chest, the lungs were healthy, as were also the right cavities of the heart; but the left cavities presented several reddish-black spots, scattered over their external surface. in the left auricle was a firm yellowish-white coagulum, adhering to an inflamed spot on its inner surface. the intestinal canal was filled with a brownish red fluid, resembling altered blood, which, in the stomach and duodenum, was of the colour of soot. the mucous membrane of these organs, as well as of the jejunum and rectum, were gorged with blood, of the colour of the lees of red wine, but without any inflammatory thickening of their coats. experiment xx. _shewing the effect of the introduction of air into an artery._ seven or eight cubic inches of common air were injected gradually into the crural artery of a large dog. a peculiar rustling noise, depending upon the admixture of the air with the blood, accompanied the operation. no particular symptoms followed; but after some minutes the corresponding vein became distended with frothy blood, which moved with difficulty, and became stagnant in the vessel. the whole limb crepitated upon pressure, but no untoward symptom presented itself for more than half an hour. an ounce of water, to which seventy drops of medicinal prussic acid had been added, was now injected into the same artery. this produced no apparent effect upon the constitution. a quarter of an hour after, an ounce of saturated solution of nux vomica was injected into the same vessel. this also was followed by no particular symptoms. an hour after the first injection, half an ounce of a weak infusion of tobacco was introduced into the same artery. excessive pain immediately followed, accompanied by great rapidity of breathing. the animal now appeared as if he were going to die; however, he slowly recovered, appeared giddy and inclined to vomit, and kept himself in a continual state of restlessness. this condition was succeeded by fever, accompanied by extreme sensibility of the limb, and irregularity of the pulse. at the expiration of some hours, he appeared better; the pulse became more regular and less feverish, but the leg continued swollen, and extremely painful upon pressure. during the night, the pain returned, indicated by howling and restlessness. there were several evacuations of fæces and urine. the following morning, there was great prostration with much fever, and apparent suffering. the limb was slightly emphysematous, swollen, inflamed, and infiltrated with serum. on the following day, two ounces and a half of water, in which some nux vomica had been boiled, were injected into the crural artery of the opposite limb. the dog expressed no pain; but, at the expiration of ten or twelve minutes, slight convulsive motions became evident, which were gradually converted into violent tetanic spasms. the animal threw himself backwards with his limbs extended, and died, after repeated convulsive attacks, an hour and a half after the last injection. _post-mortem appearances._ on opening the body, _no unusual appearances were observed in the limb_ upon which the last experiment had been tried, but the opposite one was tumid and emphysematous, infiltrated with a greyish red frothy serum of a fetid odour. _the small vessels were obstructed by firm clots of blood._ the gall-bladder was greatly distended; and the intestinal canal contained a quantity of yellowish mucus. part ii. on the introduction of vitiated fluids into the blood; its consequences, and treatment, with cases. viii. the experiments cited in the first part of this essay, illustrate the power possessed by the blood of preventing certain foreign substances from circulating with it. they shew that pus, in particular, has a tendency to coagulate the blood; and that by this means, when introduced into the vessels, its progress is arrested in some part of the circulating system. this fact, which, taken by itself, might appear of little consequence, assumes considerable importance when considered as one of the inherent properties of the blood, at all times ready, under favourable circumstances, to be called into action in the living body. the conditions under which pus will determine the coagulation of the blood, and those under which it will circulate in the living vessels, require to be accurately ascertained, before we can rightly interpret the discordant evidence which we at present have upon this point. dr. sédillot,[29] in a work recently published, mentions, that a great number of cases are met with, in which pus is poured into the general circulation without meeting with any obstruction, and states that, in such instances, he can detect the globules of pus in different parts of the circulating system. he even affirms that he can recognise a disease caused by purulent infection, by examining, under a microscope, a portion of the blood abstracted from the body. [29] de l'infection purulente, p. 399. m. dance, and, since his time, equally accurate observers, have, on the other hand, failed to detect the characters of pus in the blood, even when that fluid had been injected into the veins of living animals. the results of these different observations may perhaps be reconciled, by considering the influence exercised upon the globules of pus by the blood, before its coagulating power has been impaired. this subject appears not to have hitherto occupied the attention of pathologists. in all the cases quoted by dr. sédillot, in which he detected the globules of pus in the blood, the patients died of the disease; but in the researches instituted by m. dance and others, the experiments were made upon animals in perfect health. in the latter, the pus cannot enter the circulation, as has already been shewn, or can only do so after the blood has partially or entirely coagulated round it, and the coagulum has subsequently become broken up. in the act of coagulation under these circumstances, the appearances of the globules of pus are changed,--these being perhaps mechanically compressed by the contraction of the fibrine,--so that the most experienced eye can no longer recognise them. pus, mixed with healthy recently drawn blood, out of the body, will entirely lose its characters in this way; and as the coagulation, is by no means retarded in the living vessels, we may, without fear of contradiction, affirm, that globules of pus cannot be detected when introduced into the vessels in small quantities, and mixed with healthy blood. in cases where, from long-continued disease and the repeated introduction of vitiated fluids into the circulation, the blood has lost its power, there appears no reason to doubt the correctness of dr. sédillot's observations; and it is probable that pus-globules may then circulate with those of the blood. in experiments upon animals, it has always been found that the power of the constitution, in resisting the effects of the injection of pus into the veins, was much greater at the first than at any subsequent operation. this circumstance would appear to associate itself directly with the observations now made, and to afford another illustration of the power of healthy blood in resisting the entrance of some foreign matters into the system. from the consideration of these facts, and of the experiments previously recorded, it becomes evident, that the introduction of pus into the system through an injured or inflamed vein, can rarely be the first step towards purulent infection of the system. some change must previously have passed in the blood, by which its coagulating power is impaired, or some unusual mechanical means must have been employed, before the pus can find its way in the course of the circulation. the contradictory statements which have been made by those who have injected pus into the veins, may thus be reconciled, by taking into account the power exercised by the blood in the experiments which have been made. there can be little doubt that, while, in some instances, a portion of the pus has been forced into the general circulation, in the great majority of cases it has been detained in the vein into which it was first introduced, and has never become part of the circulating fluid. we accordingly find some experimenters recording the secondary diseases which they observed, while in other hands these appearances were not produced. dr. sédillot[30] has attempted to prove that the globules, or solid parts of pus, must be introduced into the system, in order to produce well-marked indications of purulent infection. but this hypothesis would not only appear to be at variance with the oft-repeated experiments of mm. gaspard and cruveilhier, in which similar effects were produced by the injection of mercury and of putrid fluids, but would also leave unexplained the mode of the introduction of these globules, where there is evidence that the disease has been communicated through the lymphatic system. the changes which all substances undergo in their passage through the absorbent glands, would at once forbid the idea that globules of pus could be thus introduced unchanged into the circulation; and yet we have direct evidence (case xxix) that irritating fluids are conveyed in this way into the system, and lead to the formation of secondary abscesses. [30] in deducing general conclusions from experiments upon animals, it must be borne in mind, that in them suppuration is induced with great difficulty. many of the appearances produced by the injection of putrid fluids (as in experiment xiv) would, in man, probably have terminated in suppuration. dr. sédillot has nevertheless established the fact, that, generally speaking, a different class of post-mortem appearances may be expected from the introduction of decomposed serum, to those produced from fluids containing solid particles. another class of cases, in which there would be difficulty in admitting the doctrine of the introduction of pus in substance into the circulation, presents itself, where, in the primary affections (as in case vi), no evidence can be obtained of the original lesion having suppurated. the fluids effused in such cases may be serum, lymph, or blood, mixed in different proportions; and yet the constitutional symptoms will be exactly similar to those which follow the formation of pus in other instances. there may exist, both in the primary and in the secondary affection, every intermediate gradation between the healthy secretion of a part, and the formation of pure pus, or pus mixed with blood or lymph, without any of the essential characters of the disease being absent. an inflamed bursa, or a punctured wound, without the formation of pus, (cases iv and v), may give rise to symptoms as severe, and consequences as fatal, as any that arise from the direct introduction of pus into the system. the secondary affections, in such cases, may run their course and prove as speedily fatal, as where well-formed purulent deposits have taken place. the most severe constitutional symptoms will sometimes be followed by the effusion of bloody fluid only, in one of the serous cavities (case xxx). it would be unphilosophical, even were it practicable, to refer such cases to a different disease, merely because the accidental circumstance of the formation of pus is wanting. the origin of the affection in such instances may be as well-marked, the poison can often be traced as distinctly into the system, and the secondary disease may be as clearly connected with the primary, as in any case where pus has been originally formed. in some cases again, the constitutional symptoms which accompany, or are followed by, effusions into distant parts of the body, begin before sufficient time has elapsed to allow the supposition that pus can have been fully formed at the original seat of injury. such instances occasionally, although rarely, present themselves in extensive burns and scalds, occurring in enfeebled habits, and after amputation of the limbs in scrofulous children. in nearly all cases, when the origin of the constitutional disease cannot be traced to the introduction of diseased fluid into the system through an open vein, it will be found that the part primarily injured has wanted the degree of vigour, requisite to establish and maintain healthy adhesive inflammation. upon another occasion,[31] i have endeavoured to show that, where lymph is effused around a poisoned wound, the virus will find its way less easily along the absorbent vessels, than when no such effusion has taken place; and that when, in such a wound, the effusion of lymph is checked or prevented, as by the administration of mercury, a larger proportion of cases will indicate an affection of the lymphatic system, than when the natural process has not been interfered with. there can be little doubt, that the same principle may be observed with regard to ordinary wounds. the number of cases in which the absorbents inflame, will be in inverse proportion to the number of those in which the original wounds are circumscribed by healthy adhesive inflammation. in case xxvii, it is mentioned, that the surface of a muscle, implicated in the original lesion, was as cleanly dissected as if done with a scalpel, thus showing the total absence of any surrounding effusion of lymph. the absence of, or defect in, the process of adhesion may thus be associated with inflammation of the absorbents, as the want of "union by first intention" has been shown to be connected with inflammation of the veins (section ii.) [31] london journal of medicine, vol. i, p. 799. the minuteness of the absorbent vessels, and the changes which their contents undergo in their glands, prevent any unhealthy fluids from being as readily recognised in them as in the veins. but when the progress of inflammation can be traced along these vessels from a wound, towards the centre of the circulation, marked, as it often is, at intervals, by the formation of abscesses, we cannot doubt that an irritating fluid has found its way along their canals: and when the constitutional symptoms, which arise at the same time, terminate in the formation of purulent deposits (as in case xxix), we cannot but admit that the absorbent vessels are the direct means by which, in such cases, diseased secretions are poured into the blood, and the system becomes infected. it would, therefore, appear that there are two principal conditions, under which local disease may produce a general infection of the system by the direct introduction of vitiated fluids into the blood. the first of these is connected with defective union in injured veins; the second is associated with want of healthy adhesion in inflamed lymphatics. the period of invasion of the attack differs in some degree in the different classes of cases, but it is generally marked with great precision: even when apparent recovery has been followed by a second attack, the occurrence has in each instance been accurately noted by the sudden appearance of constitutional symptoms (see case xxxvii). when one of the large veins has been originally affected, the period which elapses before symptoms of infection of the system manifest themselves, is comparatively short (case i). in cases occurring after child-birth, it is usually longer, extending to the end of the second week. after surgical operations or accidents involving some portion of bone, the access of the disease will be marked by a rigor during the third or fourth week; and finally, when the absorbent system is primarily affected, the period of the occurrence of the constitutional symptoms may be much farther removed from that of the original injury (if any such existed), and is by no means so accurately defined. at the time of the occurrence of the general disturbance of the system, the local injury or wound will generally put on an unhealthy appearance. the skin in the immediate neighbourhood will sometimes assume a dull brownish-red appearance, which will gradually fade into the colour of the surrounding parts. this symptom will usually commence near the termination of the vessels, which are derived from the same trunk as those which supply the injured part. when the original injury is complicated with a wound upon the surface of the body, it will usually become dry and glazed, and the blush upon the skin will commence in its neighbourhood, or a short distance from it, and will usually extend towards the centre of the circulation, without presenting any very defined margin: occasionally it will extend, in the form of erratic erysipelas, over a large part of the body.[32] [32] in a case of fracture of the femur into the knee-joint, i have observed a dark ill-defined erysipelatous blush extend from the affected limb to the body, and thence to the head. purulent deposits formed in various parts of the body, of which the patient died. ix. the commencement of constitutional disease, after direct infection of the blood, is marked by a sudden change in the manner and appearance of the patient; a severe rigor is usually the most prominent symptom, and is followed by much febrile excitement, or by extreme depression; a very peculiar heat of skin (case xxii) will sometimes be present, while, at other times, the surface will be covered by a profuse clammy perspiration. the rigor may be repeated at irregular intervals, but occasionally it will recur about the same hour for three or four days in succession (case xxxvii); and in a few instances it will not be observed at all. great depression frequently accompanies even the first stages of this disease, indicated by a want of tone in the pulse, by an extremely listless manner, and sometimes by a tendency to syncope (case i). the countenance becomes anxious, the tongue dry and brown in the centre, and red at the edges, or, in other instances, it presents a coating of a pasty yellowish-white colour; a dusky yellow hue frequently pervades the skin, and sometimes the conjunctivæ of the eyes. this may or may not depend upon an accompanying affection of the liver. the pulse varies much in frequency in different cases, and at different times in the same case: generally it is very rapid, especially when accompanied with much heat of skin. the pain is sometimes severe, and may be referred exactly to the spot which subsequent examination shows to have been the seat of secondary inflammation; at other times it is not confined to any particular situation, but consists of general ill-defined feelings of short duration, and recurring at irregular intervals. the peculiarity of such sensations is best expressed by the terms applied to them by the patients themselves. "catching pains all over", "soreness of the stomach", and "thrilling in the blood", not unfrequently accompany this disease. vomiting may occur, either as a symptom of constitutional disturbance, or as indicative of inflammation of an abdominal organ (case xxvi). in the latter case, it is extremely obstinate, and the fluid ejected is generally of a green colour. diarrhoea is a symptom of frequent occurrence, and appears to exercise a considerable influence on the course of the disease. its appearance will not unfrequently be accompanied by relief of the other symptoms (case iii); when it occurs, it is generally profuse, and little under the control of medicine, but, if checked, may be followed by a sudden change for the worse in the condition of the patient. the intellect is seldom affected during the first stages of the complaint; but subsequently, in severe cases, restlessness, delirium, and coma, seldom fail to succeed each other. these symptoms are all peculiar, both in regard to the rapidity with which they make their appearance, and also the sudden manner in which they occasionally disappear. the disease may seem, within a few hours, to leave a part which it has first attacked, and to fall upon a different organ in some remote part of the body. x. the post-mortem appearances observed in those who die in consequence of the introduction of vitiated fluids into the blood, cannot, for the most part, be distinguished from similar changes produced by other causes; yet there are some effects which are peculiar, and may be directly associated with the reception of foreign matter into the circulation. the most characteristic circumstance, attending the extension of disease to different organs of the body through the medium of the blood, is that several parts of these organs, or even different organs, will be simultaneously attacked. the disease will appear at once in various spots, which will become rapidly disorganized, while the surrounding textures will remain unaltered, either in structure or colour. the appearances observed upon dissection will vary according to the part attacked, and the stage of development in which the disease is found. the lungs are the organs in which the successive changes may best be observed. when puriform fluid has entered the circulation, the first appearance produced in the structure of the lungs, is that of one or more congested or dilated veins[33] of very small diameter. this will be followed by a well defined spot, of much darker colour than the surrounding texture. several of these spots will probably appear at the same time, and each one of them will soon become surrounded by a hard spherical patch of purple congestion. effusion of lymph will now take place, commencing in the centre of each affected portion, and gradually extending towards its circumference. if the disease continue, each spot will suppurate, and the different parts will become softened and broken down, in the same order in which they were previously solidified. [33] for the knowledge of this fact, i am indebted to mr. cæsar hawkins, of st. george's hospital. the liver frequently becomes the seat of secondary inflammation. in the early stage, brownish-red spots may be observed scattered through its substance. these, as they extend, assume a bluish or slate-colour; and the structure of the liver thus affected is found to have lost its consistence, and to be very easily broken down by pressure. every part affected here, as in the lungs, proceeds rapidly to suppuration; and the usual appearance presented after death, is that of several small circumscribed abscesses, around which the structure of the liver has been condensed only to a very small extent. it sometimes happens, that the larger veins in the liver become inflamed. these vessels, being held open by the firm structure of the part, are not so readily obliterated as in other situations; and it consequently happens, that the lymph and pus poured into them become irregularly mixed with the blood, more or less perfectly coagulated, which they contain: a very peculiar mottled appearance, resembling granite, is thus occasionally produced. affections of the spleen, produced by the introduction of foreign matter into the blood, are probably not so readily recognised as similar affections in the lungs and liver. for, although the spleen is often found to be diseased in those who die from infection of the blood, yet it is comparatively seldom that secondary abscesses have been found in it. in the accompanying table, containing twenty-three cases, some morbid appearance, not recognised as peculiarly the result of secondary inflammation, was observed in the spleen in no less than eight instances. so large a proportion of cases renders it probable, that the alterations observed have more than an accidental connexion with the disease of which the patient died, although they presented no characters which could be said to be peculiar to that disease. in well-marked cases of secondary affections of the spleen, one or more well defined, but frequently irregular indurations, of a chocolate colour, may be recognised; such patches are usually seen soon after the commencement of the complaint, and in a very short time become softened or broken down. the rapidity with which they lose their original character, may probably account for their being comparatively seldom observed in post-mortem examinations. deposits of lymph are sometimes met with in the kidneys; but these are of small extent, of a light colour, and resemble lymph deposited in consequence of ordinary inflammation. the patches of congestion, so characteristic of this disease in other organs, are not here observed. this may depend upon the peculiar disposition of the capillary system of the kidney. the blood has to pass through the malpigian tufts, and may be purified, or altered in character, before it reaches the proper venous system of the organ. in cases where purulent infection of the blood has been purposely produced, portions of the kidney will not unfrequently be found inflamed and firmer than natural; but, if the origin of the disease were not known these appearances could not be distinguished from those produced by inflammation of the kidney from other causes. the skin is liable to be affected in three different forms. (see cases i, ii, iii, ix, x, and xxxiv). the first of these occurs very rarely, and consists of small deposits of matter in the structure, or upon the surface of the skin, resembling in many respects the pustules of small-pox. the second form is also of rare occurrence, and consists of small congested spots on the surface of the skin. these are generally of a dark purple hue, but i have seen one case in which they were of a bright red colour. in this instance, a secondary abscess had formed in the knee-joint, and some pustules appeared upon the skin in the neighbourhood. a fortnight before the death of the patient, a number of small bright red spots made their appearance in different parts of the thigh and upper part of the leg; some of these were three or four lines in diameter while others were so small as not to be seen without attention; they appeared in accurately defined spots, of a brighter colour than the mucous membrane of the lips, and continued unchanged in appearance till death. the third form presents itself much more frequently than either of the others, although it has not hitherto much attracted the attention of pathologists, in connexion with purulent or other infection of the blood. it commences very suddenly, and frequently without any particular attention being directed to the part. a large circular patch of congestion, livid or purple in the centre, but becoming of a lighter colour towards the circumference, will form, usually upon some part of the lower extremities. the skin of the calf of the leg is perhaps more frequently attacked than that of any other part. in the centre of the congested portion, mortification very rapidly takes place, and is indicated by the part assuming a black or dull leaden colour. in some cases, it would be difficult to say where the mortification ceases, and the congestion begins; but in other instances, there is a distinct line of demarcation formed: a zone of bright red congestion will then occasionally surround the mortified part. some modifications of this third form of affection of the skin may be met with occasionally in the course of the disease. blotches assuming a livid or dusky red appearance (which gradually fades into the colour of the surrounding skin), will present themselves in different parts (case xxxvi), and terminate in thick exfoliation of the cuticle, or in small sloughs of the skin. in some instances, the superficial portions only of the skin are destroyed, and the parts beneath appear comparatively unaffected; small circumscribed portions of the outer layer of the skin will exfoliate, and the subjacent parts will heal without suppuration, by a process similar to that of scabbing (case iii). it is remarkable in this disease, that the most vascular parts are those which soonest lose their vitality. thus, in the case last referred to, portions of the surface of the skin perished, while the deeper layers recovered; again, it is not unusual to observe the whole thickness of the skin destroyed, without any corresponding affection of the cellular membrane beneath. the quantity of blood sent to a part would thus appear to favour mortification in this disease. the reason of this peculiarity will be considered in the next section. in two of the instances recorded in the appendix (cases xxii and xxvi), the lining membrane of the rectum was found of a very dark colour, and in one it had assumed a greenish appearance. this discoloration was at first looked upon as some accidental complication, or as depending upon previous disease. but m. gaspard has noticed a similar condition, after the artificial introduction of putrid fluid into the blood.[34] in one of the experiments referred to, the mucous membrane of the intestines was everywhere healthy, except in the _rectum_ and _duodenum_. in the former situation, the rugæ were prominent, and of a violet colour; in the latter, the membrane was of the colour of pale lees of wine. from the coincidence thus observed, we are led to believe that the same condition which produces congestion in the skin, may produce an analogous affection of the mucous membrane. nor must we omit to note, in connexion with this subject, the fact of the mucous membrane of the vagina being occasionally found of a dark purple colour in those who die of puerperal affections. [34] journal de physiologie, t. iv, p. 45. in the cellular membrane, serum, lymph, and pus, may be deposited, mixed with each other in various proportions. the surrounding vascularity, in these cases, is unusually small, and the lymph effused not properly organized; there is, consequently, no natural boundary to the disorganizing process, and the fluid secreted becomes infiltrated in the surrounding parts. when the muscular structure is affected, suppuration takes place with great rapidity; portions of muscles may be found quite soft, and sometimes pultaceous, in circumscribed patches, around which the fibre is perfectly healthy. pus is occasionally deposited on the exterior of muscles; and it will be then smeared over the surface, and rather infiltrated in the cellular tissue, than contained in a cyst. in the interior of muscles, there is the same absence of the natural limit to the inflammation; but, owing to the more compact structure of the part, the deposits of matter generally remain circumscribed. the brain and its membranes frequently present diseased appearances in those who die from secondary inflammation; these, for the most part, may be altogether independent of any peculiar effects of the disease; but, in some cases, it appears probable that they are not altogether unconnected with it. in one of the accompanying cases, the _pons varolii_ and _medulla oblongata_ were found of a pink colour, in consequence of congestion, where the system had become contaminated by the absorption of diseased secretion; and, in another, a layer of purulent lymph was found within the cavity of the arachnoid, accompanied by marks of inflammatory action in the fourth, and in one of the lateral ventricles. the serous membranes are peculiarly liable to be attacked by secondary inflammation; and, when affected, suppurate with the greatest readiness. they generally exhibit but a slight degree of vascularity, and sometimes scarcely appear more injected than in their natural condition. in the peritoneal cavity, large quantities of unorganised lymph are frequently poured out, mixed with turbid serum or pus. the synovial membranes of joints, when affected, appear to run directly into suppuration, and will become distended with pus in a very short space of time. the pleura, on the other hand, will seldom suppurate at first; but lymph will be deposited upon its surface, and its cavity will contain turbid serum, occasionally mixed with blood. xi. in the first sections, the changes produced in the blood, both in and out of the body, by the admixture of purulent or diseased secretions, were considered; and, in the last section, the post-mortem appearances observed in the different organs of those who have died in consequence of secondary inflammations, have been described. it now remains to connect these two series of observations, and to trace the relation that they bear to each other. the most direct way in which diseased blood produces disease in the parts to which it is conveyed, is by communicating to them its own condition. even foreign substances, which have no natural connexion with the body, may, in this way, be conveyed in the blood, and deposited in the organs of the body. hunter relates a case,[35] in which a house-painter, who had been paralytic in his hands and legs for a considerable time, had his thigh broken, and died, about three weeks after, of the accident: "on examining the body, after death, the muscles, particularly those of the arms, had lost their natural colour; but, instead of being ligamentous and semitransparent, as happens in common paralysis, they were opaque, resembling exactly in appearance parts steeped in a solution of goulard's extract. from this case it appears, that the lead had been evidently carried along with the blood into the muscles themselves. the blood can thus receive and retain extraneous matter capable of destroying the solids." [35] op. cit. p. 99. if foreign matter may, in this way, be conveyed to different parts of the frame, and there produce its chemical effects, it will readily be admitted, that a mechanical or vital action commenced in the blood,[36] may be continued in it when moved to a different part of the body. [36] it may appear unusual to speak of action going on in the blood; but, in so doing, we only illustrate the principle with which we commenced, viz., that "the blood has the power of action within itself." in those who die of secondary inflammations, the result of such actions may frequently be traced from the seat of the primary injury even to the heart itself; and, as it has already been shown that contaminated blood will communicate morbid action to the vessels in which it is contained (section iii), there no longer remains any difficulty in accounting for the sudden way in which this disease may fall upon a particular organ, or the unexpected manner in which the symptoms may shift from one part of the body to another. the conditions of the blood, which may be observed upon dissection, in this disease, so far as they tend to illustrate the present subject, may be included in two general expressions: 1st, those in which the blood has had a preternatural tendency to coagulate impressed upon it; and, 2nd, those in which its coagulating power has, to a greater or less extent, been impaired. in one case, the blood is generally found of a dark colour, with firm, and sometimes adherent coagula in the vessels; in the other, it is thin and fluid. when a preternatural tendency to coagulate has been impressed upon the blood, it will lodge in different parts of the vascular system, in situations which are most favourable to such an action; when, on the contrary, it has lost its coagulating power, extensive effusions may be expected, or the symptoms included under the term "gangrenous diathesis" may manifest themselves. as the aggregate diameter of the vessels in the body decreases, the blood in them flows with greater rapidity and force; and when near the heart, it is placed in circumstances unfavourable to coagulation, in consequence of the rapid motion there communicated to it; and we accordingly find that, although adherent coagula may be formed in the veins leading from the seat of injury, and may be traced thence through other larger vessels, they will usually terminate abruptly, when these open into the vena cava. but when the blood arrives in the cavities of the heart, the tendency to coagulate may again manifest itself. diseased coagula, presenting a "mottled appearance, partly brown, and partly of a dirty yellow colour", or "dark coloured, and partly composed of a yellowish grey opaque substance", or "with portions inelastic, and of an opaque yellow colour", will be found entangled among the projecting fibres of the auricles and ventricles. in the arteries, the blood is in the most unfavourable circumstances for coagulation during life, in consequence of the comparative smallness of their diameters, and the succession of impulses communicated to their contents; but even here, diseased and adherent coagula may be found in cases of secondary inflammations. m. cruveilhier[37] relates an instance in which, after child-birth, the pulmonary artery was found filled with coagula following its divisions. the principal clot had lost its colour, and was _adherent_ to the sides of the vessel, and contained in its centre puriform fluid. [37] op. cit. p. 669. in another case, following the operation for necrosis, the following post-mortem appearances were observed. the left lung presented, in several places, patches of red hepatization, perfectly defined, and resembling so many spots of lobular inflammation. when cut into, these patches presented several puncta of puriform fluid. the _veins_ of the lung contained fibrinous-looking coagula blocking up their cavities; and in the centre of these coagula was a whitish purulent looking fluid. the diseased condition of the blood may thus be traced visibly from the original wound, through the larger vessels, to the heart, and again from the heart to the capillary system. the disposition to coagulate, once impressed upon the blood, is not destroyed by that fluid being conveyed to a different part of the body: the action may be retarded by motion in, as well as out of the body, but will nevertheless occur when it is placed under more favourable circumstances. these circumstances, in the living vessels, are when the blood becomes separated into small quantities, and when it moves slowly along the capillaries. the blood will then coagulate in circumscribed patches,[38] as illustrated in the first characteristic marks of secondary disease which have already been mentioned as occurring in the lungs, the liver, the spleen, and the skin. the accompanying plate is taken from the lung of a donkey in which purulent fluid had been made to circulate with the blood. the stagnation of the blood, when the pus was first introduced, was mechanically prevented, and the livid spots produced by its subsequent coagulation in the capillaries of the lungs has been very faithfully represented. (see experiment no. vi.) [38] the term ecchymosis does not appear appropriate to the discoloured condition of parts observed in the commencement of this disease; the blood is not at first extravasated from the vessels, but coagulated in them. "besides the disposition for coagulation," observes mr. hunter, "the blood has, under certain circumstances, a disposition for the separation of the red globules, and probably of all its parts; for i have reason to believe, that a disposition for a separation of the red part and coagulation, are not the same thing, but arise from two different principles. this is always observable in bleeding; for if we tie up an arm and do not bleed immediately, the first blood that flows from the orifice, or that which has stagnated for some time in the veins, will soonest separate into its three constituent parts: this circumstance exposes more of the coagulating lymph at the top, which is supposed by the ignorant to indicate more inflammation, while the next quantity taken suspends its red parts in the lymph, and gives the idea that the first small quantity had been of such service at the time of its flowing, as to have altered for the better the whole mass of blood. best, therefore, maybe regarded as one of the immediate causes of the separation." _hunter_, p. 29. this disposition of the blood to separate into its constituent parts is evinced in a very marked degree in one class of secondary affections. extensive effusions of serum, lymph, and pus, mixed in different proportions, will take place in the serous cavities of the body, and become infiltrated in the cellular membrane, accompanied with very slight indications of inflammatory action. the colouring matter of the blood will also sometimes become effused with its other parts; but when this is the case, the blood will be found to have lost its coagulating power: in this respect presenting a direct contrast to the effusion from a healthy wounded vessel. the lymph deposited will be found lying in unorganized flakes, wanting its usual adhesive properties, and very slightly attached to parts, presenting little or no increased vascularity. the rapid manner in which these depositions take place, shows that they are separated from the blood without undergoing any very elaborate process. in this condition of the system, any organ upon which the disease falls, may rapidly become disorganized, or may readily mortify; and, after death, a tendency to rapid decomposition will be manifested. the veins on the surface of the body may frequently be traced as dark blue lines, as though the skin covering them were stained by the colouring matter of the blood. the lungs and other organs may, under these circumstances, be found in every grade of disorganization, till they present all the characteristics of gangrene: even the peculiar fetor which accompanies mortification of the lung, will, in some instances, be present. a tendency to the formation of petechial spots may also be observed in different parts; and even the organs which do not appear to have been the peculiar seat of the disease, will be found to have lost their consistency, and to break down upon comparatively slight pressure. mr. hunter found, that in proportion as the blood retained the power of coagulation, it had the power of resisting putrefaction; and conversely, we observe that, in this class of cases, the deficiency of the former is accompanied in a marked manner by the absence of the latter. the two conditions of the blood which have now been mentioned, appear to bear a direct relation to the two classes of post-mortem appearances, observed in cases of secondary inflammations: the first being generally connected with congestion of different organs during the first stages of the disease, the second with extensive effusions, accompanied with comparatively little vascularity. xii. the treatment of secondary inflammations naturally divides itself into local and constitutional, both as regards the primary lesion and the subsequent affections. the circumstances which interfere with union by the first intention in veins, have been shown to be the same as those which precede the formation of purulent deposits, in a large class of cases. whatever then tends to favour the healthy reparation of a wounded vein, may be regarded as affording security against any subsequent disease; and the chief point in the local treatment is, perhaps, to prevent any accidental circumstances from interfering with the natural process of repair. when the powers of the constitution are enfeebled, even the natural motions of a part may interfere with recovery, and rest sometimes becomes an important object in the treatment. how necessary this is after child-birth, when the divided veins are being closed, every one who has attended such cases practically knows. again, after bleeding, the arm will inflame in a much greater proportion of cases, when the patient is obliged to follow his usual occupation, or when, from accidental circumstances (as from the pain experienced in case i), the arms are kept in motion. it has occurred to me, to see the symptoms of purulent deposits set in, on the day following prolonged attempts to bring fractured portions of bone into position. in all such cases, any external violence (as in experiment no. vi), or even the motion of the body, as in dr. davis's case (section iv) may loosen the coagula formed, either between the wounded edges, or in the cavities of veins. in the treatment of the local injury, a valuable hint has been left us by mr. hunter, connected directly with the consideration of the pathology of the disease. "the way in which sore arms after bleeding come on, shows plainly that they arise from the wound not healing by the first intention"; and he recommends that the two sides of the vein should be approximated by a compress, until union of the divided edges has taken place. it has been shown upon very high authority, that the sides of a vein do not unite after venesection (as has sometimes been presumed to be mr. hunter's opinion); but that the divided edges only of the vessel are agglutinated by the coagulum, which "serves as a bed to the new membrane." but the case is different, should this first attempt at union fail; the sides of the vessel may then become united, and its cavity for a time obstructed (section iv). the approximation of the sides of the veins would materially facilitate this action, which is the natural security, under the circumstances, against the admission of foreign matter. when an abscess is suspected to have formed in a vein, a similar mode of treatment is recommended by hunter; the compress, in this case, being placed between the inflamed part and the centre of the circulation. in the pathological museum of the college of surgeons, one of mr. hunter's preparations (no. 1728) exhibits such a case, where, from the imperfect union of a vein, the contents of the abscess had become mixed with the blood. as the process of reparation has been variously described by authors, so the different theories propounded have led to different kinds of treatment. at the veterinary college, even within the last few years, it was publicly taught, that a coagulum in a vein was a foreign substance, and ought to be removed; and the jugular vein in horses which had been bled, was sometimes slit up for several inches, in order to remove the coagula which formed in successive portions of its course. that a coagulum in a vein may be an irritating substance has been fully proved (sections i and ii); but the irritation depends upon the accidental admixture of foreign matter: and the inflammation of the veins, produced by the contact of impure blood, requires to be carefully distinguished from the natural mode of union by the first intention. to remove coagula which have formed round purulent secretion (if such could be recognised), might be to remove a cause of irritation; but to remove them in ordinary cases, is to remove the very means prepared by nature for the restoration and safety of the part. in operations involving large vessels, the local conditions which may influence the actions in the veins, appear not to have been fully determined; for while some surgeons regard the tying or cutting of a vein as a serious operation, others are in the habit of doing it without any unusual precaution. in operations upon hæmorrhoidal tumours, the veins involved are of some size, and in two of the instances recorded in the appendix, a ligature applied to them was followed by purulent deposits. in the usual mode of passing a needle armed with a double ligature through the base of such a tumour, the hæmorrhoidal veins are necessarily sometimes wounded, and there is danger that, in tying the ligatures, the sides of a wounded vein may be drawn asunder. the vessel may thus be held open, and be in a similar condition to the vessels contained in bony structures. a safe way of performing this operation, when admissible, is to destroy a portion of the mucous membrane with strong nitric acid. the blood in the vessels then becomes charred, and their cavities obstructed, till they are permanently closed by adhesive inflammation. every means of treating a local injury which tends to produce healthy union or adhesion, may be considered in some sort as a preventive mode of treatment. position, topical applications, bandages, and temperature, may all have their influence in producing these healthy actions; but, as the wounds which precede purulent deposits are generally characterized by feeble powers, those conditions which tend to invigorate the parts are principally indicated. "when action is greater than strength, whatever has the tendency to raise the power above irritability should be used: the object of this practice consists in bringing the strength of the constitution and parts as near upon a par with the action as possible, by which means, a kindly resolution, or suppuration may take place, according as the parts are capable of acting." the irritability of a wound frequently appears nothing else than a series of attempts to bring about an action, which it has not the power to accomplish: as soon as that is fulfilled, which the necessity of the parts demands for their healthy condition, irritation will cease. in such cases, everything that will confer strength to carry out the intended action, will prevent inflammation. but no local applications will be sufficient to produce this effect, unless the powers of the constitution are supported at the same time. a heavy man received a wound in the back of his head from an iron spike; he was kept very low, complaining occasionally of want of food. repeated hæmorrhage took place at intervals of a day or two, which no local applications could suppress, and he ultimately died from loss of blood. the wound was found to extend through the bone into the lateral sinus, which contained only some fluid blood. no inflammatory action had taken place within the skull, nor had any attempt apparently been made to close the wounded vessel. any vitiated secretion in contact with the lacerated edges of the vessel would, in such a case, have free access to the circulation. the constitutional treatment of cases, liable to be succeeded by purulent deposits, is most important; for during the healing of the primary wound, the system may be influenced by remedies, which may be subsequently quite useless. it is evident, observes m. cruveilhier,[39] that the treatment of phlebitis ought to be concentrated on the first period of the disease, viz., that of the coagulation of the blood; for as soon as pus has become mixed with the circulating blood, medicine is generally of no avail. when there are indications of the extension of inflammation along a vein, the mode of treatment usually adopted in this country has been the administration of calomel and opium; and, in france, general bleeding, but especially the application of large numbers of leeches. "we may subdue inflammation of veins, whatever their situation, by general blood-letting, and especially by local bleeding, repeated sufficiently often and in sufficient quantities!"[40] it is true that patients recover after such treatment; but the published records of cases not unfrequently terminate with such a description as the following: "the patient was repeatedly bled, and with apparent relief every time, the blood being extremely sizy. _two days, however, previous to death, the vital principle was so exhausted as to need the use of cordials!!_" [39] op. cit. p. 662. [40] op. cit. p. 662. if the explanation of the mode of adhesion in veins already given be correct, neither the propriety of bleeding, nor of the administration of mercury, as a rule, derives much support from a consideration of the pathology of the disease. careful comparative experience is still wanting, before we can form a satisfactory judgment of the value of these remedies. the theoretical views upon which they have been adopted, are confirmed neither by the statistical records of cases, nor by the principles of sound physiology. the numerical evidence which we have in some instances, even tends to indicate an opposite plan of treatment. at a period when puerperal fever was rife, forty cases, attacked with some form of the disease, "were treated without any bleeding or leeching, or without any attempt to induce the constitutional effects of mercury; and of these, only two died."[41] "in irritable habits, when the inflammation becomes more diffused," says mr. hunter, "bleeding should be performed with great caution: even a quick, hard pulse, and sizy blood, are not always to be depended upon as sure indications of bleeding being the proper method of the resolution of the inflammation; more must be taken into the account. the kind of blood is of great consequence to be known; for although it should prove sizy, yet if it lies squat in the basin, and is not firm in texture, and if the symptoms at the same time are very violent, bleeding must be performed very sparingly, if at all; for i suspect, that under such a state of blood, if the symptoms continue, bleeding is not the proper mode of treatment. if we had medicines which, when given internally, could be taken into the constitution, and were endowed with a power of making the vessels contract, such, i apprehend, would be proper medicines. bark has certainly this property, and is of singular service, i believe, in every inflammation attended with weakness; and therefore, i conceive, should be oftener given than is commonly done." [41] ferguson (dr.) on the diseases of women. these cases formed one-fifth of the whole number treated. in bleeding women suffering from puerperal fever during an epidemic, in which the disease frequently terminated in purulent deposits, i have occasionally seen an irregular transparent bluish layer form upon the surface of the blood, almost immediately after the operation; in consequence of this, a repetition of the bleeding was sometimes had recourse to, when the subsequent stages of the disease appeared to indicate that it had not been required. the transparent layer of lymph on the surface of the blood, may, in such instances, be only an indication of its tendency to separate into its different parts, as previously described. large bleedings, under such circumstances, inasmuch as they tend to diminish the already enfeebled power of coagulation in the blood, may predispose to the infection of the system, and to the formation of purulent deposits. the influence of mercury upon the system, as illustrated in case xxvi, may have the same tendency. the action of mercury, so far as it can be traced upon the surface of the body, is certainly unfavourable both to union by the first intention, and to adhesive inflammation; and, inasmuch as the safety of the patient, after an injury or wound, depends upon the due performance of these processes, its effect upon the system must be regarded as of, at least, doubtful advantage. when salivation has been induced, serum is poured out, and the texture of the gums is loosened and rendered spongy. when lymph is effused upon the iris, the action of mercury loosens its adhesions, and dissolves its connexions; it cannot, therefore, be supposed that its effect upon the system should render the union of divided vessels stronger, or the newly-formed adhesions in wounds, firmer. the cases in which purulent deposits usually form, indicate a debilitated state of constitution. they are of much more frequent occurrence in large towns than in the country, and in hospital than in private practice. the depressing influences which give rise to erysipelas, or puerperal fever, will also predispose to the formation of these abscesses; and as scanty diet, loss of blood, debilitating surgical operations, and over-crowded rooms, have been found among the causes of the former, so may they be looked upon as favouring the production of the latter. the treatment of inflammation of the veins, in which purulent deposits frequently originate, is thus spoken of, after matured observation: "all the experience that i have had on the subject, would lead me to believe that, like erysipelas, it has its origin in a low asthenic state of the system, and that those persons are especially liable to it, who have been much lowered by hæmorrhage at the time of an operation, or by too scanty a diet afterwards. an operation is a shock upon the system, making a great demand upon the vital powers. the effects of this shock are often much aggravated by loss of blood, and a very scanty diet actually makes the patient more liable to some kinds of inflammation. our mode of practice ought to be rather to sustain his powers by allowing him wholesome nourishment, and not to add to the influence of the other depressing causes, the still worse one of starvation."[42] [42] brodie (sir b. c.) medical gazette, vol. xxxvii, p. 642. the lowering influence of mercury may be considered in a similar way. there can be little doubt that while, on the one hand, it favours the absorption of vitiated fluids, it may, on the other, render the system less able to resist the injurious consequences which they produce. as many circumstances, besides mere debility, tend to depress the vital powers, so tonic medicines, and a generous diet, must not be looked upon as the only preventive modes of treatment. each case that occurs in practice may present some peculiarity; in one case, the patient will be found to have previously suffered from diabetes; in another, from disease of the spleen; and in a third, from organic disease of the kidney; and, in each of these, a peculiar mode of treatment may be required. the general management of this disease, after the formation of purulent deposits has commenced, is probably as little satisfactory as any that come under the notice of the surgeon. the whole character of the affection is characterized by what has been aptly designated as action without power. the excitement of the system will imitate all the acts of genuine inflammation, without any of its healthy results; and loss of energy will appear immediately after, or even arise in conjunction with, the first symptoms of increased action. in the treatment of such cases, it must be borne in mind, that the secondary inflammations are not the disease, but the effect of a concealed cause, which may develope itself in any part of the system; and that, while the relief of one organ is sought by depletion or mercurial remedies, additional vigour may be given to the latent evil, so as to render it more ready to develope itself in some other part. when purulent deposits occur, the sudden congestions, which indicate their commencement, are not accompanied by any reparative actions, and the lymph, which is effused in the second stage of their formation, is not so disposed as to circumscribe and limit the inflammation; there is, therefore, no natural process by means of which such collections of fluid can be evacuated; hence, when situated near the surface, they should be opened as soon as they are detected. it will sometimes happen, that, after the symptoms of secondary inflammation of internal organs have commenced, an abscess will present itself near the surface of the body, and relief will be afforded to the part first affected; at other times, an obstinate and violent diarrhoea will precede recovery. although the mode of treatment adopted may have little influence either in bringing on, or checking, such salutary actions, it is important to watch their occurrence, and perhaps still more important, to be careful not to mistake a remedial action for a symptom of the disease. "what treatment," says cruveilhier, "shall we oppose to purulent infection? to this question experience is as yet dumb, while theory would seem to point to diffusible stimuli and tonics; to ammonia, quinine, and sudorifics; to hot external applications, to the vapour baths, to purgatives, and especially to emetics; to tartarized antimony, in large doses; to vesicatories, and to strong diuretics. calomel has been extensively employed, to create a fluxion from the intestinal mucous membrane; but all these means have failed as signally in my hands as in those of others; yet, when the injection of putrid matters into the veins of living animals has been followed by abundant and very fetid evacuations, they have usually got well. it is a fundamental fact of pathology, that the intestinal canal is chiefly affected in diseases caused by miasmata. i am certain that diseases resulting from purulent infection would not be stamped with the seal of incurability, and that nature, seconded by art, would triumph in the majority of cases, if the pus, which is incessantly renewed, did not incessantly renew the sources of infection. as soon as constitutional symptoms manifest themselves, neither general nor local bleeding affords any advantage. a portion of the _materies morbi_ is, no doubt, abstracted with the blood; but, as it is constantly being reproduced, the constitution is only deprived of the power it would otherwise have of resisting the disease."[43] in accordance with this remark, m. gaspard found that animals, which recovered after the injection of a certain quantity of pus into their veins, often died when the experiment was repeated. the recovery was usually preceded by black, liquid, and extremely fetid evacuations, which often seemed to afford immediate relief. when such evacuations have taken place in other diseases, the gall-bladder has been found distended with black bile;[44] and it appears probable that the liver, in these cases, is one of the principal organs through which the cleansing of the system is attempted. if the supply of morbid matter to the system could be checked, mercurial action, in this stage of the disease, might be of service, by enabling the liver, or other organs, to throw off their vitiated secretions. when patients recover from purulent deposits (cases iii and xxvii), they are often left in a debilitated and languid state, in which ordinary tonics exercise little influence. the consequences of the disease appear to hang about the system, long after the cause which gave rise to it has ceased. the pulse will sometimes continue irritable, and there will be a tendency to derangement of the secretions of the skin, bowels, and other organs, accompanied by occasional slight attacks of fever. in this condition, an alterative course of mercury, combined with sarsaparilla, has been found beneficial. these remedies, by stimulating the activity of the excreting organs, may assist the constitution in throwing off the disease; and their mode of action may be the same as in other cases, where the system has been infected by an animal poison. [43] op. cit. p. 662. [44] i have observed this condition after injuries of the spine which proved fatal, by causing inflammation of other parts. appendix of cases. a. cases of secondary inflammation, accompanied by mortification of the skin. case i. william ford, 33, an apparently healthy man, was seized with the symptom of strangulated hernia, at harrow, december 28th. he was bled in both arms; but, as the hernia remained unreduced, he was sent to town, in a state of considerable restlessness and suffering. during his journey, the hernia returned of its own accord. he left quite relieved, and remained well till the 31st, when he had a rigor. on the 1st of february, there was a considerable degree of febrile excitement, and the anterior part of the left arm was red, swollen, and painful upon pressure. the tenderness and pain soon extended up the arm, in the course of the cephalic vein: the redness assumed the character of erysipelas. on the 3rd, he suffered from sickness, the matter vomited being green and acid. he had two severe rigors, followed by great heat of skin, and a quick full pulse. the orifice in the left arm discharged a thin serous fluid. on the 4th, he complained of stiffness in the right arm; also of being very feeble and faint. 5th. wandered much during the night. the right arm was a good deal swollen about the end of the elbow-joint, and presented a patch of a bright red colour above the condyle. the pulse was weak and tremulous; motions of the hands were occasionally observed. he complained of pain in the ring-finger of the right hand, and in the ball of the right great toe. the skin, in both these situations, had assumed a red appearance. 6th. was delirious during the greater part of the night; countenance expressive of much anxiety; pulse very weak; tongue covered by a brown dry fur; profuse perspiration; complained of severe pain in the calves of his legs. he died during the following night. _post-mortem appearances._ a small deposit of thick pus was found on the external surface of the left cephalic vein. the blood was coagulated in its cavity, its coats were thickened, and its lining membrane appeared very red. this redness could be traced, though in a less degree, through the whole extent of the vena innominata. on the right side, the cellular tissue, both above and below the elbow-joint, was greatly distended with serum. the cephalic vein of the right arm presented marks of having been inflamed; but not nearly to the same extent as upon the opposite side. the joints in which pain had been experienced during life, were distended with turbid pus; deposits of pus were also found in the anterior mediastinum, and between the oesophagus and trachea. a large gangrenous spot was observed in the skin of the calf of the right leg. the subjacent cellular tissue was much distended with serum. case ii. richard mason had a small cancerous tumour removed from the lower lip. the operation was performed in the usual way, and the wound appeared to heal by the first intention; a small abscess, however, followed by some ulceration, subsequently appeared in the neighbourhood of the cicatrix. nine days after the operation, he complained of sore throat and general uneasiness, and three days afterwards he was seized with rigors, followed by cold perspiration and coma. _post-mortem appearances._ a small deposit of matter was found, situated beneath the fascia of the left thigh. the synovial membrane of the left knee was highly inflamed, and contained a large quantity of pus. on the right side, the skin of the whole inferior extremity presented a dark livid appearance, with the exception of that situated upon the fore part of the thigh. the same dark colour was observed in the muscles of the limb, which were infiltrated with blood and serum. the arteries and veins were discoloured, but in other respects presented nothing remarkable. it was ascertained, that, two years previously, this patient had suffered from diabetes; and upon examining the urine found in the bladder, it was found to contain sugar. case iii. jane thornton, æt. 32, came under treatment on the 22nd of march. a week previously, her right ancle had become red and painful, and inflammation subsequently extended up the inner side of the leg. when first seen, she was evidently much out of health, although no one organ could be said to be particularly affected. on the 28th of march, she was attacked with severe rigors, and experienced pains in different parts of her limbs: the rigors were repeated for several days in succession. the inflammation of the leg now entirely disappeared, and she complained of pain in the right knee, which was slightly swollen. on the 31st, her bowels became much relaxed; there was great general depression, and much nervous agitation. both knees were swollen. the general symptoms now became somewhat relieved; but on the 4th april, she was attacked with vomiting, which recurred frequently during the day, and was accompanied with great depression, and severe pain in the epigastrium. on the 5th, the sickness continued, apparently quite uninfluenced by any remedies. she passed considerable quantities of blood by stool: her countenance presented a dusky yellow hue: the pulse was excited, without power, and the sense of depression was greatly increased. on the 7th, the vomiting still continued, and she still passed blood by stool. some spots of a dark purple colour now made their appearance upon her face. the hands both became slightly swollen; and upon the right one, some small, dark, livid spots, similar to those upon the face, made their appearance. she was much troubled with hiccough. on the 9th, the countenance was very anxious, the complexion more sallow: some more livid spots appeared upon the face and cheeks. the right hand and arm were swollen and painful: some fresh livid spots appeared, upon the knuckles. complained much of faintness: had extreme debility with occasional hiccough: pulse extremely weak: the surface of the body was covered with cold perspiration. the sickness had entirely ceased, and there was no blood in the motions: the tongue was rather dry in the centre, but tolerably clean. 10th. she wandered slightly during the night, and vomited once: some blood again appeared in the motions; the right hand and arm were less swollen. 11th. the countenance was anxious, the pulse about 90, and intermitting irregularly. the vomiting recurred several times. the livid spots on the right hand had not increased in size, but appeared like distinct small black superficial sloughs of the skin; these all scabbed off, without suppuration. 12th. the pain and swelling of the arm had nearly subsided. the bowels acted very freely with the aid of medicine, and she expressed herself much relieved. from this time the patient slowly but gradually improved, with one or two slight intermissions, till the beginning of may, when she again complained of pain at the inner part of the right arm, above the elbow. some hardness could here be felt in the course of the basilic vein. some small collections of matter were now deposited upon the back of the right hand, resembling, in some respects, the eruption of confluent small-pox. on may 11th, she had regained much of her strength, but still felt some pain in the elbow upon motion. she also complained of the joints of one of her fingers. she now left london for change of air. b. _the following table is formed of cases taken consecutively during one year._ --------------------------+-----------------+------------------------ | period | heads of cases. | of secondary | post-mortem | inflammation. | appearances. --------------------------+-----------------+------------------------ case iv. elizth. | a few days after| dark-coloured serum, mackintosh, æt. 25. | the appearance | mixed with shreds of inflamed bursa patellæ;

has a constant short cough; perspires very freely. 26th. the pulse has become weaker, but remains of the same frequency (130). it communicates a peculiar jerking sensation to the finger. 28th. pulse 96, weaker; slight diarrhoea; he vomited several times during the day. 29th. restless, with delirium. 30th. passed another restless night, but became better in the course of the day; his appetite returned. _oct._ 5th. his appetite again failed; complained of a sense of distension in the abdomen. 8th. an abscess was discovered at the lower and back part of the right leg; the skin over this presented various shades of yellow and brown, giving the appearance of having been extensively bruised. about two ounces of discoloured pus were evacuated, together with a considerable quantity of grumous blood. 10th. has much improved since the last report; the wound discharges dark semi-coagulated blood. 13th. a second abscess now presented itself in the same leg, and the skin covering it assumed the same discoloured appearance as in the first instance. when opened, it discharged dark-coloured semi-coagulated blood with the matter. he now rapidly improved in health, and at length perfectly recovered. case xxviii. samuel todd, æt. 58, fell from a wagon fifteen miles from town, and was brought up in an open cart, during a sharp frost. there was a compound fracture of the left leg. two days afterwards, he suffered from cellular inflammation around the wound. on the 24th day, he had a slight rigor, and complained of slight stiffness in the right shoulder. he ate and drank well till within two days of his death, which took place on the thirty-fourth day. _post-mortem appearances._ both lungs contained secondary abscesses, in various stages of formation. the left external iliac and common femoral veins were blocked up with firm coagula, and confined by these was a quantity of purulent-looking fluid; an adherent layer could, for some distance, be peeled off the internal surface of these vessels. case xxix. james howard, æt. 33, had a small abscess in the dorsum of the right foot, which was followed by inflammation of the absorbents; abscesses subsequently formed in the right thigh and groin. two months after the first appearance of the abscess on his foot, he was seized with rigors, vomiting, and profuse perspiration. he complained also of pain in the lower part of the left lung, and it was said that the respiratory murmur was deficient in this situation. he died on the 23rd day from the appearance of the symptoms of the secondary affection. post-mortem appearances. the skin and conjunctivæ were of a light yellow colour; there were incisions in the right groin. in the cavity of the right pleura, were some patches of recently effused lymph, of a yellowish colour. in the lower lobe of the right lung, were several patches of secondary deposit; these were found in different stages of their formation, and some of them were of considerable size; some of the pulmonary veins, in the neighbourhood of those which had suppurated, were found to contain a fluid resembling pus. on the left side was a small abscess, under the pleura costalis. the liver was healthy in structure, rather larger than usual. kidneys healthy. the veins in the groin presented a healthy appearance. case xxx. a gentleman was operated upon for hæmorrhoidal tumours in the usual manner, and died shortly afterwards, with effusion of bloody serum into one of the pleural cavities. the only peculiarity that could be detected in the appearance of the rectum was, that the blood was still fluid in one of the largest veins. this vein led directly to an ulcer produced by the operation; and, even at its extremity, it contained no appearance of coagulum. d. cases in which vitiated fluids were observed in the veins of the uterus after child-birth. case xxxi.[45] on the second day after a natural labour, a woman had prolonged rigors, which were followed by abdominal pain and much perspiration. on the fourth day, she was affected with syncope and bilious vomiting, accompanied by extreme prostration. on the fifth day, the abdominal pain, which had subsided, re-appeared with agitation and delirium. on the sixth, she had cold sweats, irregular pulse, rapid breathing, and vomiting. she died on the following morning. _post-mortem appearances._ there was a small quantity of limpid serum in the cavity of the peritoneum. some of the uterine veins were found to contain a turbid fluid. the heart was half filled with brown blood. the lungs were congested, and the other organs natural. case xxxii. a woman, twenty-two years of age, of a nervous temperament, miscarried at the expiration of the first month. she was almost immediately afterwards attacked by rigors and bilious vomiting, accompanied by pains in the loins and in the hypogastrium. on the following day, there was coma, with indications of extreme debility. on the third day, consciousness returned. there was difficult articulation, and moaning. the extremities became cold, the pulse imperceptible, and death occurred upon the same day. [45] this, and the two following cases, are taken from tonellé. the author is responsible for the accuracy of all the preceding cases. _post-mortem appearances._ the peritoneum was slightly injected, and contained a small quantity of reddish serum. the cervix uteri was covered with a layer of pus. semi-transparent lymph was found in some of the uterine veins. the brain, and other organs, were found healthy. case xxxiii. a feeble girl, 21 years of age, was confined at the expiration of the eighth month. on the fourth day, there was shivering and prolonged fainting. the following morning, she had acute abdominal pain, fever, and diarrhoea. on the seventh day, the symptoms had all subsided, but on the eighth the abdominal pain returned, accompanied by syncope. she died two days afterwards. _post-mortem appearances._ the peritoneum was slightly injected, and contained about a pint of red-coloured serum. the uterus was large, white, and firm, its veins half filled with fluid blood; its lymphatics natural; its inner surface lined with a layer of fetid brown blood, but otherwise healthy; the cervix covered with a grey, thin exudation. the lungs, heart, brain, and other organs, were quite sound. case xxxiv.[46] anne biggs, æt. 39, confined march 18th, 1830, eighth child. on the evening of her confinement, her manner was much excited. on the 19th, she was incoherent, and complained of pain in the calf of the right leg, which was tender on pressure. the pulse being hard, she was bled to eight ounces. on the 28th, the leg was swollen and white; the pain in it much increased: towards evening the calf of the limb became black, while, at the tendo-achillis, the skin was hot, tender, dry, and mottled. the bowels were much opened, the head giddy, the pulse quick and strong. she was again bled, to twenty-six ounces, and twelve leeches were applied to the temple. on the 21st, there was nausea, vomiting, and diarrhoea. on the 23rd, she complained much of the confusion in her head, the leg was tolerably easy, but the upper and inner part of the thigh was very tender. on the 24th, the diarrhoea continued, and there was increased weakness. a hard swelling, about half as large as an egg, appeared at the wrist, and one of the orifices made by venesection was black and painful. she died in the evening. [46] dr. ferguson. _post-mortem appearances._ all the ventricles of the brain were dilated with serum, and there was a good deal of effusion into the arachnoid and pia mater. the viscera were perfectly healthy, except the heart and spleen: the latter was very large, and on pressing it, a large quantity of dirty red pulpy matter exuded. the lining membrane of the right auricle and ventricle, when washed, had a dark red hue. the femoral vein, just at the ingress of the saphæna, and the superficial vein in the back of the leg, had their coats much thickened, so as to cut like arteries. their lining membrane was similar to that of the right cavity of the heart. when they were divided, purulent matter, mixed with thin light-coloured blood, escaped. the cellular tissue forming the sheath of the femoral vessels, and on the calf of the leg, shewed marks of recent inflammation; but there was no appearance of pus in these situations. none of the glands in the groin or ham were enlarged. the inferior vena cava appeared healthy. e. cases of purulent deposits, connected with inflammation of the veins after delivery, recorded by dr. robert lee in the med.-chir. transactions. case xxxv. mrs. mayhew, æt. 33, was delivered on the 2nd march 1829. on the 5th, there was a discharge of blood from the uterus. from the 6th to the 20th, she made no complaint of uneasiness in any region of the body, though her strength rapidly declined. the countenance was of a dusky yellow hue. the heat of the surface slightly increased; the respiration hurried, particularly on bodily exertion, and the pulse above 130, and feeble; the tongue pale and glossy, with loss of appetite. the lochial discharge had a peculiarly offensive smell. she died upon the 28th of march. _post-mortem appearances._ when the uterus was laid open, there was found to be a portion of the placenta, about the size of a nutmeg, in a putrid state, adhering to its inner surface. the substance of the uterus, to the extent of an inch around this, was of a peculiarly dark colour, almost black, and as soft as a sponge. on cutting into it, about a teaspoonful of purulent matter escaped from the veins, and a small additional quantity was pressed out from them.... on opening the capsular ligament of the right knee-joint, about six ounces of thin purulent matter escaped, and the cartilages of the femur and tibia were extensively eroded. there was no appearance of inflammation, however, on the exterior of the capsular ligament. the right wrist was swollen, and the cellular membrane around it was unusually vascular, and infiltrated with serum. case xxxvi. mrs. pope, æt. 40, was delivered, on the 26th of oct., of her fourteenth child, and appeared to recover favourably until the 3rd of nov., when she was suddenly attacked with a severe rigor. this was followed by intense head-ache, vomiting, general soreness of abdomen, and suppression of lochia. nov. 6th. great prostration of strength; laborious respiration, with pain at the bottom of the sternum, and frequent hacking cough; pulse 135, extremely feeble; skin hot and dry.... occasional retching and vomiting. several hard, lumpy cords were found running up in the inside of the thigh, in the direction of the superficial veins. 7th. delirium; general debility greatly increased; the surface of the body was covered with a yellow suffusion; the middle finger of the left hand was much swollen around the second joint, and the skin covering it was of a dusky red colour. case xxxvii. mrs. edwards, æt. 35, was suddenly attacked, three weeks after delivery, with pain in the calf of the right leg, and loss of power in the whole right inferior extremity. on the 5th day from the attack, a considerable swelling, without induration, had taken place from the ham to the foot, and great tenderness was experienced along the inner surface of the thigh to the groin. the extremity became universally swollen, painful, and deprived of all power of motion. the temperature along the inner surface of the limb increased; the integuments were pale and glistening, not pitting upon pressure. the femoral vein, from the groin to the middle of the thigh, was indurated, enlarged, and exquisitely sensible; pulse 80; tongue much loaded; thirst; bowels open. on the 23rd day from the attack, the disease was apparently declining. the femoral vein could no longer be felt, but there was still a sense of tenderness in its course down the thigh, and she experienced considerable uneasiness between the umbilicus and pubes, as well as in the loins. she now, for the first time, began to have rigors, accompanied by a quick pulse, loaded tongue, and thirst. from this period to the 31st day, the swelling of the limb and tenderness in the course of the femoral vessels subsided, but she experienced attacks of acute pain in the umbilical region, loins, and back, which assumed a regular intermittent form. every afternoon there was a rigor of an hour's duration, followed by increased heat, and profuse perspiration: the skin was hot and dry; pulse 125; tongue brown and parched; bowels open. these febrile attacks gradually declined in severity, and she appeared to recover till the 43rd day, when she had a long and violent fit of cold shivering. the countenance now became expressive of great anxiety, and the pulse extremely weak and feeble. 45th day. vomiting; pain upon the left side, increased upon taking a deep respiration. 46th day. another severe and prolonged rigor; skin hot and dry; pulse 140; tongue brown and parched; diarrhoea; respiration hurried, with frequent cough; surface of body presenting a peculiar yellow tinge. the conjunctiva of the right eye now suddenly became of a deep red colour, and so much swollen, that the eyelids could not be closed. on the day following, the left eye also became red and swollen, the surface of the body was cold and clammy, pulse 140, extremely feeble, with great debility, and repeated attacks of vomiting. from this date, the patient lived nearly three weeks, but for the last fortnight the vision in both eyes was entirely destroyed. _post-mortem appearances._ the left pleural cavity contained upwards of two pints of a thin, purulent fluid. the inferior lobe of the left lung was of a dark colour, and soft in texture. in its centre, about an ounce of thick cream-coloured pus was found deposited in its dark and softened texture. this was not contained in any cyst or membrane, but was infiltrated into the pulmonary tissue. the coats of the vena cava inferior were considerably thickened; its whole cavity was occupied by a coagulum, terminating above in a loose pointed extremity. the left common iliac vein was plugged up, by a continuation of the coagulum from the cava. the coagulum was continued beyond the entrance of the internal iliac, which it completely closed, and terminated in a pointed extremity about the middle of the external iliac. neither the remainder of the vessel, nor the femoral vein, exhibited any morbid changes. the right common iliac vein was contracted to more than one-half its natural size; it was firm to the touch, of a greyish blue colour; to its internal coat adhered an adventitious membrane of the same colour, containing within it a firm coagulum. the internal iliac was rendered quite impervious by dense, dark coloured bluish membranes; and, at its entrance into the common iliac, it was converted into a solid cord. the contracted external iliac contained within it a soft yellowish coagulum; its coats were three or four times their natural thickness, and lined with dark-coloured membranous layers. the right femoral vein, from poupart's ligament to the middle of the thigh, was diminished in size, and almost inseparable from the artery. its tunics were thickened, and its interior coated with a dense membrane, surrounding a solid purple coagulum strongly adherent to it. f. case, shewing the period at which a coagulum may give way in a wounded vessel. case xxxviii. george haydon, ætat. 37, received a wound about half an inch in length over the right radial artery, on march 5th, 1848. the hæmorrhage was arrested by pressure. on the 12th, a small slough formed in the bottom of the wound, the edges of which were inflamed and painful. on the 14th, slight bleeding from the wound occurred, which at first was arrested by the application of cold; but in the evening it recurred in considerable quantity, and again was checked by cold and pressure; during the night, however, profuse hæmorrhage again took place, and was only stopped by the application of the tourniquet above the elbow. on the 15th, the radial artery was tied; but as this did not prevent the hæmorrhage from returning, when the tourniquet was relaxed, the original wound was enlarged. the opening in the radial artery was now with some difficulty discovered; it extended two-thirds round the circumference of the vessel, leaving one-third undivided. g. cases shewing the organisation of the outer layer of extravasated blood; reported by mr. hewett. case xxxix.[47] a middle-aged man received a severe injury of the chest; he lived eleven days after the accident, and during this time he never presented a single inflammatory symptom. the cavity of the left pleura was found completely filled with bloody fluid, and was subdivided into two compartments, by a portion of coloured fibrine, presenting a honeycombed appearance, which passed from the ribs to the lung. the lower compartment was itself subdivided into several others, by layers of coloured fibrine intersecting each other. large portions of loosely coagulated blood were found in all the cavities; some of these clots were of a rusty colour, others approached nearer to the natural colour of the blood. the lung was compressed against the spine, and the whole surface of the pleural sac was coated by a false membrane, about two lines in thickness, formed by coagulated fibrine. the fibrine which lined the pleura pulmonalis and pleura diaphragmatica, presented on its inner surface a smooth and polished appearance, and in colour exactly resembled the yellowish fibrine found in the clots of the heart of this patient. so uniform was the coating, and so continuous was it throughout its whole extent, that it looked at first merely like thickened pleura; but this appearance was easily destroyed, by peeling off this adventitious membrane from the serous tissue, which there presented the same appearances as the pleura on the opposite side, with the exception of not being quite so smooth: there was neither thickening nor the slightest increase of vascularity in this pleura. a large rent, from which the hæmorrhage had proceeded, was found in the substance of the lung. [47] med.-chir. transactions, vol. xxviii. case xl. a man was attacked with diffuse cellular inflammation of the inferior extremity, which terminated in two days with extensive gangrene of the skin. in the superficial and common femoral veins were extensive coagula; these did not completely fill the veins, but slightly adhered at different points to their internal coats. these clots still retained, in some places, the colouring matter of the blood, whilst at others the colourless fibrine alone remained; in both veins, the clots were enveloped in a perfectly transparent, smooth, and polished membrane, presenting the appearance of a serous tissue. in the structure of these membranes were several distinct arborescent vessels, minutely injected;[48] some of these vessels were of sufficient size to allow of the blood being made, by gentle pressure, to circulate through them; but no communication could be traced between these vessels and the coats of the veins. the membranes were easily peeled off from the surface of the clots with which they were in contact. the interior coats of the veins presented their natural colour and polished surfaces, except at the points where the slight adhesions above-mentioned existed. [48] mr. gray, the curator of the museum of st. george's hospital, has recently shewed me the outer layer of an effusion of blood into the arachnoid cavity, injected from the middle meningeal artery. finis. richards, printer, 100, st. martin's lane. * * * * * transcriber's notes page 81, case xxvii. aug 5th follows september 30th. this has been changed to oct 5th. italics are represented thus _italic_. this treatise on the diseases of women is dedicated to the women of the world. yours for health lydia e. pinkham this entire book copyrighted in 1901 and 1904 by the lydia e. pinkham medicine co., of lynn, mass., u. s. a. all rights reserved and will be protected by law. list of lydia e. pinkham's remedies. +illustration of products+ lydia e. pinkham's vegetable compound. put up in three forms: liquid, lozenge, and pills price, $1.00 lydia e. pinkham's liver pills, per box " .25 lydia e. pinkham's blood purifier " 1.00 lydia e. pinkham's sanative wash, per packet " .25 all the above, excepting the liquids, can be sent by mail on receipt of price. all druggists sell mrs. pinkham's remedies. chapter i. a woman best understands a woman. =experience a perfect teacher.=--do you know what it is to suffer pain? have you had your body racked and torn with intense suffering? have you ever experienced that indescribable agony which comes from overworked nerves? have you ever felt the sharp, stinging pain, the dull, heavy pain, the throbbing, jumping pain, the cramping, tearing pain, the sickening, nauseating pain? then you know all about them. nobody can tell you anything more. experience is a perfect teacher. =book-learning alone not sufficient.=--suppose you had never experienced pain, but had just read about it in a book, do you think you would have any kind of an idea of what genuine suffering was? most certainly not. book knowledge is valuable. it teaches the location of countries, the use of figures, and the history of nations; but there are some things books cannot do, and the greatest of these is, they cannot describe physical and mental suffering. these are things that must be experienced. =personal experience necessary.=--after you have once suffered, how ready you are to sympathize with those who are going through the same severe trials. if a member of your own home or a friend is passing through the trying ordeal of motherhood, and you have suffered the same, how you can advise, suggest, comfort, guide! if you have had a personal experience of intense agony once every month, do you not think you are in a far better position to talk with one who is suffering in the same way than you would be if you had never gone through all this? =you best understand yourself.=--but let us go a little farther in this study. when you listen to an eminent orator, you have but little idea whether he is nervous or not, but little idea whether he is undergoing a severe strain or not; for you have never been in his place, cannot understand just that condition. men become greatly interested in political matters; perhaps it often seems to you that they become too much disturbed; and yet how can you judge, for you have never been in their place? and so we might go on, giving illustration after illustration as additional proof to this one great fact. it takes a woman to understand a woman. =man cannot know woman's suffering.=--what does a man know about the thousand and one aches and pains peculiar to a woman? he may have seen manifestations of suffering, he may have read something about these things in books, but that is all. even though he might be exceedingly learned in the medical profession, yet what more can he know aside from that which the books teach? did a man ever have a backache like the dragging, pulling, tearing ache of a woman? no. it is impossible. =even medical men cannot understand these things.=--to a man, all pain must be of his kind; it must be a man-pain, not a woman-pain. take, for instance, the long list of diseases and discomforts which come directly from some derangement of the female generative organs; as, for instance, the bearing-down pains, excessive flowing, uterine cramps, and leucorrhoea. do you think it possible for a man to understand these things? granting that he may be the most learned man in the medical profession, how can he know anything about them only in a general way? you know, we know, everybody knows that he cannot. a woman can best prescribe for a woman. =relief first offered in 1873.=--away back in '73 these thoughts came to lydia e. pinkham. she saw the most intense suffering about her on every hand, and yet no one seemed able to give relief. her thorough education enabled her to understand that nearly all the suffering of womankind was due to diseases and affections peculiar to her sex. the whole question resolved itself into just this: if a remedy could be made that would relieve all inflammations and congestions of the ovaries, fallopian tubes, uterus, and other female organs, the days of suffering for women would be largely over. =first made on a kitchen stove.=--could this be done? mrs. pinkham believed with all her heart that it was possible. so on a kitchen stove she began the great work which has made her name a household word wherever civilization exists. without money, but with a hopeful heart, she made up little batches of this remedy to give to neighbors and friends whom she felt could be relieved by it. the story soon spread from house to house, from village to village, from city to city. now it looked as if a business might be established upon a permanent basis, a basis resting upon the wonderful curative properties of the medicine itself. ="we can trust her."=--by judicious advertising the merits of this remarkable remedy were set forth; and before she was hardly aware of it, she found herself at the head of one of the largest enterprises ever established in this country. that face so full of character and sympathy, soon after it was first published, years ago, began to attract marked attention wherever it was seen. women said, "here is one to whom we can tell our misery, one who will listen to our story of pain, one whom we can fully trust." and so the letters began to arrive from every quarter. now hundreds of these letters are received every day. more than a hundred thousand were written in a single year. everyone is opened by a woman, read by a woman, sacredly regarded as written strictly in confidence by one woman to another. men do not see these letters. =men never see your letters.=--do you want a strange man to hear all about your particular disease? would you feel like sitting down by the side of a stranger and telling him all those sacred things which should be known only by women? it isn't natural for a woman to do this; it isn't like her, isn't in keeping with her finer sense of refinement. =no boys around.=--and then, how would it be when some boy opens the letters, steals time to read a few before they are handed to some other boy clerk to distribute (and probably read) around the office to the various departments? it makes one almost indignant to think how light and trivial these serious matters are so often regarded. =you write to a woman.=--but when you know your letter is going to be seen only by a woman, one who sympathizes with you, feels sorry for you, knows all about you, how different all this seems. =confidence never violated.=--although there are preserved in the secret files of lydia e. pinkham's laboratory many hundreds of thousands of letters from women from all parts of the world, yet in not a single instance has the writer accused mrs. pinkham of violating her confidence. =the largest experience in the world.=--the one thing that qualifies a person to give advice on any subject is experience--experience creates knowledge. no person can speak from a greater experience with female ills nor a greater record of success than mrs. pinkham. thousands of cases come each month, some personally, others by mail; and this has been going on thirty years, day after day, and day after day, thirty years of constant success--think of the knowledge thus gained. surely women are wise in seeking advice from a woman with such an experience--especially when it is free. if you are ill get a bottle of lydia e. pinkham's vegetable compound at once--then write mrs. pinkham, lynn, mass. what medical man has ever lived who has prescribed for so many women? what whole corps of physicians in any hospital or medical college has answered so many letters, or treated in any way so many patients? =she helps everyone.=--no woman ever writes to her for advice without getting help. no matter how rare you think your case may be, she is almost certain to find letters on file asking advice for other cases of the same kind. by special permission of the writers i print a few of the letters showing what cures have been effected. but if the reader could go through these secret files which are never shown, she might hour after hour, day after day, week after week, spend her whole time reading letters, each one telling some special story of rescue from serious illness, intense suffering, or impending death. =the largest record of cures.=--the writers of these letters are found in every clime and there is hardly a country in the world without its multitude of grateful women cured by lydia e. pinkham's medicines. they have the largest record of absolute cures from female ills known to have been effected by any physician or his medicines. chapter ii. what shall the future generation be? =important to the nation.=--it is impossible to fully comprehend how important to us as a nation is the health of the young women of to-day. we fail to realize that these women are to be the mothers of the next generation, and that in their hands will lie, in large measure, the power to form the characters and direct the destinies of the boys and girls of the future. =woman must be strong.=--we may educate our young men all we wish, yet we cannot have national power through their strength alone. the women of the country must have this physical education if we are to have a people that is strong and hearty. upon the sound health and vigor of the young women of to-day will depend, to a large extent, the health and capacity of the future generations. =what are girls worth?=--it is estimated that there are about twelve million young women in the united states between fourteen and twenty-eight years of age. what are these young women worth to the home, to the state, to the nation, to the human race? this is largely a question of physical health. it is the stern duty of the mother to make this clear to her daughter, and it is the solemn duty of every young woman to thoroughly study the subject herself. =not prepared for motherhood.=--but largely through ignorance, often through indifference, these young girls become mothers when little prepared to do so, and they find not only their own health shattered thereby, but also that they are the mothers of weak, delicate, and perhaps deformed children. =women desire children.=--we read a great deal in the newspapers about how american women are doing everything they possibly can to prevent having children. this is not in accord with our experience. it is a slander on american womanhood,--it is an outrageous falsehood. in not one letter in a thousand which we receive do wives ask how childbearing may be prevented, while every day brings us many, many letters asking if something cannot be done in order that there may be a baby in the house. =a healthy mother and child.=--if you desire a child, you wish a healthy child; and you certainly desire to be a strong mother, one capable of caring for her infant in every way, and able to direct it all through its young life. then let us give you some advice. =why some women do not have children.=--the reason why some wives do not have children may be entirely the fault of the husband; but if this is not the case, then in all probability there is some inflammation of the generative organs. this may be of recent or of old standing. it must be thoroughly removed before the impregnated egg from the ovary can become attached. =the cure for this condition.=--that these changes can be brought about in a vast number of cases i have the most positive testimony. i have advised such wives to continually use lydia e. pinkham's vegetable compound; and, with this treatment alone, such a healthy condition of the generative organs has been brought about that pregnancy has very soon followed. this is precisely according to nature's laws, as i have indicated before. therefore, i say to every wife who desires a child, "give lydia e. pinkham's vegetable compound a thorough trial. if the fault is yours, the compound will surely remove it, and the longing of your heart will be satisfied." chapter iii. reproduction. =the reproductive instinct strong.=--the reproductive instinct is very strong in the human race, as is indicated by the large amount of energy the woman expends in the bearing of children, and by both sexes in the care and education of their young. as we know, it is only by the production of new individuals that the continuance of the race is assured. =problems of reproduction.=--the problems of reproduction are extremely broad, involving not only the immediate questions of individual reproduction, but also those broader and deeper ones which relate to heredity. =a new life, by chance.=--it is a most astonishing fact that nearly all persons born into the world are given life as the result of chance rather than by careful design. "if my parents had only known!" is the frightful wail of many a wretched life. =to create is divine.=--at no time does man come so near being omnipotent as when, by the tremendous powers given him, a new life is called into existence. and yet, whether strong or weak, refreshed or exhausted, healthy or diseased, sober or intoxicated, sweet or ill-tempered, yielding or resisting, a new life is begun which may be either of two extremes. how great are such questions! the human mind seems appalled when asked to consider them. =education on these subjects necessary.=--it is not the purpose of this book to moralize upon these themes, or to say what should and should not be done; but knowing something of the wretchedness of womankind, and the fearful slavery she often has to endure, i can only hope, with all my heart, that the coming generation may be better educated on these most important topics. it is with a thought or two of this kind in mind that i append the following brief outline of this subject:-=two sexes necessary.=--in the higher animals two sexes are necessary for the reproduction of the race, the male and the female. each contributes some particular element toward the beginning of a new life; this is known as the germ-cell. =the germ-cells.=--the germ-cells of the male are called spermatozoa, and those of the female, ova. the reproductive process is simply a fusion, or union of these male and female germ-cells. =the male elements.=--the spermatozoa are exceedingly delicate and minute; they constitute the greatest part of the semen, or sperm. they are peculiar shaped bodies, having a head, body, and tail, as illustrated in the accompanying figure, and they can only be seen by powerful magnifying glasses. (fig. 1.) ~fig. 1. at the left are six spermatozoa, or male-elements, male germ-cells. at the right is an ovum, egg, female germ-cell. all highly magnified.~ they have the remarkable property of moving about with considerable activity, and their number is almost beyond computation. =only one male element necessary.=--although this number is so vast, yet only a single one is required to endow the female cell, or egg, with life. it is another illustration of how nature does everything possible to increase the chances of perpetuating the race, for without such immense numbers, the chances of the female egg being fertilized would be much less. =may live for days.=--although these male elements can live but a few hours outside of the body, even when especial precautions are taken to make every thing favorable to their existence, yet they have been known to maintain their full life in the vaginal canal for more than eight days after their discharge; another remarkable provision of nature, for the prolonged existence of these cells increases the probability of the fertilization of an egg, and thus increases the chances of producing a new life. =the female element.=--as i have already said, the female germ-cell is also known as the ovum, or egg. a single ovum is shown in fig. 1. if not fertilized by the male elements, the egg passes off into the outside world; if fertilized, it stops in the cavity of the uterus, where it forms an attachment. here it remains until perfectly developed, when, at the end of nine months, it is brought forth to the outside world as a perfect infant. =one female element; many male elements.=--the human ovum is often said to be a miniature of the egg of the common fowl, although there are some quite marked differences between the two. it is a very interesting fact to note that there is only one egg given off at a time; while there are many thousands of the male elements. this is in harmony with the larger size of the egg, and the fact that while this egg awaits fertilization it is most carefully protected within the body of the mother. =where is life first made?=--where the wonderful union of the male and female elements takes place is not definitely known, although it is generally believed that it is upon the surface of the ovary, itself. if this be true, then it is necessary for the male element to traverse the whole length of the uterine cavity, out along the course of the fallopian tube, and there be deposited on the surface of the ovary. =the fertilized egg.=--when a fertilized or impregnated egg is set free from the surface of the ovary, it follows the same course that the unimpregnated egg does until it reaches the uterus. here some most remarkable changes immediately take place whereby the egg is held firmly to the inner wall of the uterine cavity; while the unimpregnated egg, as i have said, passes down the uterine cavity into the vagina, and thus out of the body. in other words, the fertilized egg is retained within the body, while the unfertilized one is cast off. =one egg discharged each month.=--an ovum, or egg, is discharged during each menstrual period. it cannot be seen because of its minute size, a magnifying glass being necessary to detect it, even under favorable conditions. at just what time during this period the ovum is cast from the body is not definitely known, but it is generally thought to be toward the latter part. =time when fertilization is most probable.=--from this it is seen that but one egg fully develops and ripens ready to be fertilized each month. as it is the ripened egg which is thrown off at each menstrual period, therefore it follows that the fertilization of this egg would be most probable at about the time of menstruation. =times when ova do not ripen.=--as a rule, these ova do not ripen, or develop, either during pregnancy, or during the nursing of the child, although there are certain exceptions to this rule; for menstruation occasionally takes place during lactation and pregnancy, and pregnancy itself may occur while the mother is nursing her child. chapter iv. the remedy that cures. =a vegetable compound.=--i hardly think it necessary to mention in detail the separate ingredients of lydia e. pinkham's vegetable compound. we wish to call your attention, however, to that word "vegetable." i do not believe in mercury, arsenic, and the host of mineral poisons which are found in so many remedies. when taken into the system they disturb every function, interfere with the most vital processes, and produce the most disastrous consequences. =the purest and best.=--knowing these things, mrs. pinkham was exceedingly careful to put only the purest and choicest of products of the vegetable kingdom into her compound. each of the roots and herbs is selected with the most extreme care, and all are prepared under the personal supervision of the most thoroughly trained specialists. =one secret.=--one great secret of the success of lydia e. pinkham's vegetable compound is that each vegetable is so treated that all useful elements are retained, and all useless discarded. =highly concentrated.=--for instance, it is possible for the expert workmen in our laboratory to condense all the medicinal power that exists in a pound of the coarse root into a mass no larger than could be held on the point of a knife. in this way it is possible for a teaspoonful of the vegetable compound to represent all the curative properties usually found in eight or ten times that quantity; in other words, it is highly concentrated. =acts upon female organs.=--mrs. pinkham knew from the very first that she was on the right track. she knew that her vegetable compound contained medicines which act directly and naturally upon the female organs. she knew that one ingredient produced certain effects on the uterus, while other ingredients tended to relieve pain in the ovaries. she knew that one remedy would heal an inflamed uterine cavity, while another ingredient would cause better circulation in the blood-vessels of this part of the body. having the theory all worked out most carefully, she awaited the practical test, feeling confident as to the result. =success was immediate.=--but she did not have to wait long. immediately the cures began, and her neighbors and friends told each other what had been done for them. soon letters came by the hundreds from all parts of the world. thousands upon thousands have written to mrs. pinkham telling her their story, and giving to her, also, full permission to use their testimonials. =it bridges the gulf.=--i am sure you would be delighted, as well as surprised, if you could see the immense difference between the first and last letters received from women. the first is the story of suffering, of extreme agony with prolonged misery and abandoned hope. the last is a song of gratitude, of great love, of joy and peace. the first tells of disease, the last of health. but what an immense gulf between these two!--a gulf, however, i am glad to say, that can be bridged with lydia e. pinkham's vegetable compound. =you cannot possibly doubt.=--i do not believe you can possibly doubt for one moment the power of this marvelous remedy to cure the diseases of women. how can you doubt it? for a quarter of a century it has gone into every city, village, and hamlet in our land, and into almost every country home. across the water it is finding its way among the rich and the poor. no remedy was ever known that was so generally used. wherever there are women, there are suffering women; and wherever there are suffering women you are sure to find lydia e. pinkham's vegetable compound. =the testimonials are true.=--do you think there are hundreds of thousands of your own sex who would wilfully falsify? do you think that any could be found who would deliberately do this, and without hope of gain or reward? yet i could point you to hundreds of thousands of letters received from women who write from the fulness of the heart to thank us for what we have done for them. =we speak strongly.=--then am i not justified in speaking strongly to you? don't you think we feel sure of our position? i certainly know what we have done for others, and that makes us feel sure we can do the same for you. =we can cure you.=--i believe our vegetable compound will cure you. i believe it will cure every case where a cure is among the possibilities. you need not be particular whether the soreness in the lower part of your body is in the right side or the left side; whether the pain is sharp, or dull and heavy; whether you suffer terrible agony each month with local pain, or whether it is mental depression; whether the flow is too scant or too profuse. =it corrects the wrong.=--you need not be particular about these things, for they all show that something is wrong, and lydia e. pinkham's vegetable compound corrects this wrong. that is what it was made for; that is precisely the work it does. =have faith in us.=--don't purchase a bottle thinking you will "see what it will do," having made up your mind that you will "try the experiment." don't come in this spirit, for there is no need of it. come with the feeling that has inspired so many thousands of your sisters,--come believing that you have at last found a remedy that will relieve you from this terrible slavery to suffering. i am anxious to have you enjoy all the robust health that is your right. i am anxious to make you happy, hopeful, healthy. put your confidence in lydia e. pinkham's vegetable compound. you will never be disappointed. chapter v. the female pelvis and its contents. =the pelvis.=--the pelvis is the bony framework which forms the lower part of the body. on each side it forms a union with the hip bone to make the hip joint. the female pelvis contains the reproductive organs (uterus, vagina, and ovaries), and also the bladder and lower bowel. fig. 2 gives a very good idea of the shape and general structure of this bony framework; while a careful study of fig. 3 will enable one to form a very correct idea of the relative size and position of the various parts contained in this framework. ~fig. 2. the female pelvis. the flanging sides form the hips. the union of the bones in front forms the pubic arch which is felt at the front of the lower part of the body. the lower end of the spinal column, or backbone, is seen at the back of the figure.~ =the vagina.=--the vagina is a membranous canal extending from the surface of the body to the uterus, or womb. its posterior wall is about 3-1/2 inches long, and its anterior about 3 inches. a careful study should be made of our illustration, in order that the relation of the vagina and uterus to the rectum behind and the bladder in front may be thoroughly understood; also the angle which is formed by the vagina and the uterus. notice should be taken, also, of the opening of the uterus into the upper part of the vagina; as inflammation of the uterus often causes a discharge which passes into the upper part of the vagina and finally out of the body. this gives rise to the belief that the only trouble is in the vagina itself, whereas the real seat of the disease may be high up in the uterus. ~fig. 3. a lateral view of the contents of the female pelvis. 1. the vagina; 2. uterus; 3. bladder; 4. lower bowel; 5. bone forming the pubic arch; 6. the spinal cord, with bone in front and back of it.~ =the uterus.=--the uterus, or womb, is a hollow organ formed of muscular tissue, and lined with a delicate mucous membrane. the bladder is in front, the rectum behind, and the vagina below. =three parts.=--physicians divide this important organ into three parts,--the fundus, body, and neck. the fundus is all the upper rounded portion; the body all that portion between the fundus and the neck; and the neck all the rounded lower part. =the cavity of the uterus.=--this is divided into the cavity of the body and the cavity of the neck. by consulting our illustration it is seen that these cavities differ greatly in shape; that of the body being triangular, while that of the neck is barrel-shaped. by referring again to fig. 4 it will be seen that the cavity of the body has three openings, one on either side at the top going to the fallopian tubes, and an opening at the bottom passing into the cavity of the neck. a constriction exists between these two cavities; but after childbirth this is largely done away with, and there is not that marked difference which existed formerly. =glands in uterus.=--in the mucous membrane lining the uterus are vast numbers of minute glands which secrete mucus. it has been asserted that in the cavity of the neck alone there are from ten to twelve thousand of these glands. it is in this mucous membrane that such remarkable changes occur each month during menstruation, and still more wonderful changes during pregnancy. =the ligaments of the uterus.=--by referring to fig. 5 it will be seen that there are on each side of the uterus flat bands of tissue known as "broad ligaments." these ligaments are attached to the sides of the pelvic cavity, and aid greatly in holding the uterus firmly in place. there are also other ligaments concerned in this same work, although the broad ligaments are most important. the illustration also shows the walls of the vagina cut open, in order that the position of the mouth of the uterus may be easily seen. ~fig. 4. this illustration shows the cavities in a uterus which has been pregnant. 1, the vagina; 2, cavity of the neck of the uterus; 3, cavity of the body, above which is the fundus of the uterus; 4, fallopian tubes, extending to the ovaries.~ ~fig. 5. the female generative organs. 1, the vagina; 2, uterus; 3, broad ligament of left side; 4, a smaller ligament; 5, fallopian tube; 6, ovary; 7, fringed end of fallopian tube.~ =blood-vessels surrounding uterus.=--the uterus is well supplied with blood-vessels, as fig. 6 shows. indeed, there is all over the walls of the uterus and through its tissue a vast network of these vessels. whenever, for any reason, the circulation of the blood through the pelvis is disturbed, these blood-vessels are likely to become engorged, over-filled, producing congestion and inflammation. ~fig. 6. the blood-vessels of the right side of the uterus. 1, blood vessels; 2, end of the fallopian tube; 3, ovary; 4, right edge of uterus.~ =all parts closely related.=--the close relation of these blood-vessels to the blood-supply of the bowels, liver, etc., makes it possible for most serious disturbances to take place even from slight causes. =study the illustrations.=--by studying these illustrations it can be readily seen how an over-distended rectum may produce such an impediment to the circulation that there will be congestion of all the neighboring parts. or, the intestines themselves may become over-distended with fã¦cal matter, or gas, from dyspepsia, and the pressure induced thereby may be sufficient to interfere with the free circulation of these parts, and thus uterine congestion produced. it is also seen how improper dress may compress the organs about these parts, and thus interfere with the circulation. again, it is easily understood, simply from studying the illustrations alone, how any of these causes might produce dislocation of the uterus itself. =object of uterus.=--the uterus is the source of the menstrual discharge, a place for the foetus during its development, and the source of the nutritive supply of this foetus. it is the uterus which contracts at full term and expels the child. =uterus not rigidly fixed.=--in a perfectly normal condition there is considerable mobility to the uterus; in other words, it is not fixed firmly by the ligaments already mentioned. it is rather simply suspended, or hung in the pelvic cavity, by these broad flat bands of tissue. a full bladder will push it backward, while a distended rectum will move it forward; as the body changes its posture, so will the uterus change its position by force of gravity. =cannot be bent upon itself.=--the uterus cannot be bent upon itself without producing injury; neither can it be pushed too far forward or backward, nor crowded down too far without causing great distress and actual disease. =fallopian tube.=--figs. 4 and 5 show that there is given off from each side of the upper part of the uterus a tube. this is called the fallopian tube. each tube is about four inches long. near the uterus its cavity will just admit an ordinary bristle; but near its free end, at the ovary, it is as large as a goose-quill. it is a peculiar tube in that it terminates in a number of fringe-like processes, one of which is always attached to the ovary itself. ~fig. 7. part of an ovary, showing a ripe ovum, or egg, about to be cast off, as occurs at each menstrual period. it is here this egg may be fertilized or impregnated by the male elements.~ =object of this tube.=--the fallopian tube conveys the sperm of the male from the uterus to the ovary, and also takes the germ-cell (or ovule, or egg) from the ovary to the uterus. when a ripe egg is about to be discharged from the ovary, one of these fringe-like processes of the fallopian tube grasps it and receives it into the mouth of the tube, whence it is conveyed directly into the uterine canal. =ovary.=--on each side of the uterus and in each side of the pelvic cavity is an ovary. it is about one and a half inches in length, three-fourths of an inch in width, and one-third of an inch in thickness. it weighs from one to two drachms, and is an elongated, oval-shaped body. ~fig. 8. this figure illustrates the course followed by an ovum. the ripened egg leaves the ovary (1), passes down the fallopian tube (2), and thence into the uterine cavity (3).~ ~fig. 9. an exceedingly minute piece of an ovary, highly magnified. it shows eight ova or eggs.~ =object of ovaries.=--the ovaries are the essential organs of generation in the female. in each ovary are large numbers of cells, ovules, or eggs, one of which, at least, is supposed to pass into the uterine cavity with each menstruation. anatomists tell us that each human ovary contains as many as 30,000 of these ovules, or eggs. local treatment.--fast passing away. =it makes one indignant.=--when i recall the terrible and almost horrible treatment which women have had to undergo in the past, i cannot help but become deeply indignant. it seems as if all medical study had gone for naught, as if the teachings of nature had been forgotten, and most of all, as if no such thing as delicacy and modesty existed. =this makes confirmed invalids.=--it is only necessary for a woman to complain of discomfort in the back, a bearing-down pain, or some unnatural discharge, when some physician says that local treatment, and local treatment only, must be taken. women so thoroughly understand what their physician is going to say that they do not consult him, but go on suffering more and more until they become almost confirmed invalids. others, after they are told what must be done, return home and become gloomy and melancholy over the outlook. =specialists are crazy for work.=--the specialists are so crazy for this kind of work that it seems as though they would gladly scrape and burn the inside of the stomach for dyspepsia, if they could do so! or, they would take a long probe and go down into the interior of the lungs and apply strong caustics, if such a thing were possible! =the patient is deceived.=--if the ache, or the pain, or the discharge was on the back of the hand where it could be seen, and where these "treatments" could be watched, the specialists would have a hard showing indeed, for the patient herself would then see that little good came from these local applications. but being situated within the body, so that only the physician himself can examine the parts, the patient has to rest content, not knowing whether a little pure water is applied (and the fee collected), or whether the strongest acids which burn deep into the tissues are used (and the fee collected). =local treatment unnecessary.=--now all of this is almost invariably unnecessary. it is not showing ordinary common-sense, not in accord with nature, and not in keeping with the best medical science of to-day. yet thousands upon thousands of women are undergoing the worst kind of mental and physical torture in taking these local treatments, while all the savings of the household have to go toward paying the enormous bills of the specialist. =the true doctor not blamed.=--_do not misunderstand me, please. i am not talking against doctors, not against the real, true, genuine, noble physicians and surgeons._ there is no nobler profession than that of the physician, none practiced more faithfully than the good old family physician of this country practice theirs. the best of them are glad to help their patients in any way they can, and in spite of professional prejudice, many have tried lydia e. pinkham's vegetable compound upon their patients and have been delighted at the wonderful success of the trial. =nature the best teacher.=--the trouble with so many of these physicians who call themselves "specialists on diseases of women" is that they get it into their head that they know more than nature. they map out a course of their own, and pay no attention whatever to the laws of health. just as if a dog barking at the moon would make it shine less brightly! now any one who has given any thought to the preservation of the health can readily understand how impossible it would be to cure an inflammation of the uterus or ovaries, or check an unnatural discharge from the vagina, by applying strong acids, nitrate of silver, pure carbolic acid, strong tincture of iodine, or other destroying, caustic, irritating, and dangerous drugs. all of these must be injurious, must postpone recovery, and if their use be continued for any great length of time must make a cure quite impossible. =a good medicine needed.=--of course what is needed in these cases is something that will restore the natural circulation of the blood through the tissues of the uterus, something that will relieve congestion and cure inflammation. when the swelling and irritation have subsided, then the nerves are no longer irritated, and all pain disappears. =what this will do.=--then all these parts become better nourished, the weakened and diseased tissues take on new strength, and all unnatural discharges cease. when the relaxed ligaments are properly fed and toned up, then they hold the uterus in its natural position, and all bearing-down pains and other symptoms of displacement quickly disappear. of course this constitutional treatment with lydia e. pinkham's vegetable compound is hastened by keeping the parts perfectly clean, which can be easily done with lydia e. pinkham's sanative wash. =a hearty welcome to the perfect cure.=--a hearty welcome to the most scientific treatment; a hearty welcome to the most natural, the most easy, and the most perfect method of cure; a hearty welcome to lydia e. pinkham's vegetable compound; a hearty welcome to the remedy that never fails to restore the uterus to perfect health and natural position. chapter vi. menstruation. =occurs monthly.=--once every twenty-eight days very remarkable changes occur in the uterus, giving rise to that peculiar monthly periodicity called menstruation, monthly sickness, monthlies, or being unwell. although this usually occurs once in about four weeks, yet it may be a week less or a week longer; or, indeed, the variation may be even greater than this. =symptoms of its approach.=--as a perfectly natural menstrual period approaches, there is a certain degree of discomfort and lassitude, a sense of weight in the lower part of the body, and more or less disinclination to enter society. these symptoms may be slightly pronounced or very prominent, for it is quite unusual to find a person who does not have at least some general discomfort at this time. =its appearance.=--first there is a slight discharge of mucus which soon becomes of a rusty brown or yellow color from the mixture of a small quantity of blood. by the second or third day the discharge has the appearance of pure blood. the unpleasant sensations which were so marked at first now gradually subside, and the discharge, after continuing for a certain number of days, grows more and more scanty. the color changes from a pure red to a rusty tinge, and finally disappears altogether. then the ordinary duties are resumed. =the age of puberty.=--menstruation begins at about fourteen or fifteen years of age, this period being known as "the age of puberty." it is preceded and attended by peculiar signs. the whole figure becomes more plump and round, the hips increase in breadth, and the breasts rapidly develop. the more striking changes, however, occur in the inclinations and emotional susceptibilities. =age modified.=--a great many circumstances modify the age at which the first menstruation takes place. in hot climates this takes place earlier, the difference between hot and cold countries being as great as three years; yet heredity has more to do with this than anything else. "as was the mother so is the child" is a common saying among women. =continues about thirty years.=--the menstrual function continues active from this age until about the forty-fifth year, although this may be extended even ten years later. during all these years the woman is capable of bearing children, because at each month there has been a fully developed ovum, or egg, ready to be fertilized. =the change of life.=--when the menstrual function ceases, then the period of childbearing is over. the time of its disappearance is known as "the change of life, or menopause." =amount of monthly loss.=--the amount of blood lost during menstruation varies greatly with different individuals, and it would be quite impossible to give anything like an accurate rule. it varies, normally, from one to eight ounces, the average being probably about five ounces. =duration of period.=--the duration of the period is from one to eight days, the average being five days. hence it will be seen that the average loss of fluid per day would be about one ounce. =loss should be small.=--it should be stated here that, as a rule, those enjoy the best health who lose but a small quantity of blood at this time. some persons seem to think that a very free discharge is necessary, and that they feel better at such times; but there is no possible reason why this should be the case. =the first menstruation.=--the appearance of the first menstruation is a most critical time in the life of every young girl, and the mother should be prepared to give her daughter the best of advice. some slight inattention, some undue exposure, some thoughtlessness due entirely to ignorance on these great subjects, may change the whole future from a life of comfort and good health to prolonged days of misery and intense suffering. =menstruation and childbearing.=--it is the belief at the present time, among all who have studied this subject, that menstruation is closely connected with the function of childbearing. the changes which take place each month within the uterine cavity are of precisely the proper character to prepare this tissue for the reception of the fertilized egg. =rules to be observed.=--a few rules should be carefully followed during each menstruation, in order that future trouble may be prevented. first of all, it is necessary to avoid taking cold; yet a person should not stay in the house by the side of a fire, or in a warm room all the time, for this would increase the susceptibility to cold. care should be taken to avoid undue exposure, for nothing will disturb the menstrual process quicker than the sudden chilling of the body, especially when moist with perspiration. intense mental excitement should be avoided, also. if the young girl is at school, she should be told to study more lightly at this time; while any great excitement of any kind, as giving way to anger, or extreme merriment, should be avoided. the feeling of debility and depression which usually accompanies this time is a gentle warning by nature that the body should remain quiet and at rest. it is natural for many persons to be especially depressed at this time; an effort should be made by those who understand the situation to make everything as agreeable and pleasant as possible to the sufferer. =danger to school girls.=--without the slightest doubt, many women are suffering intensely to-day who might be enjoying the best of health had they not been obliged to study so intensely while in school. a moderate amount of study does no harm at this time, but the dread of examinations, with our modern system of cramming at certain times of the school year, has, without doubt, so worked upon the nervous system that many a life has been made miserable as a result. =danger to office girls.=--it is astonishing, when one fully understands the processes of menstruation, how so many girls and young women can remain all day behind the counter in the store, or at the work-table, during these few trying days, and even escape without serious illness. employers never think of the subject, and there is a natural delicacy on the part of those most concerned to mention the subject. there should be in all such establishments some woman to whom these girls could confide their condition. this woman, or overseer, could easily be made responsible for the apparent neglect of duties by these girls at such times. =criminal carelessness.=--how often is it true that young ladies attend balls, skate, and otherwise recklessly expose themselves at this most critical time. one is almost inclined to call such exposures really criminal, because of the terrible consequences so sure to follow. a simple wetting of the feet, or resting quietly in a draught after exercise, during menstruation may impose upon the person a life-long injury. how carefully, then, should mothers watch their daughters at these periods, and how strongly should they impress upon them the necessity of special care. =condition of bowels important.=--the condition of the bowels should also be carefully looked after at these times. indeed, this is so important that it should never be neglected. there should be at least one good movement of the bowels each day. nothing can more certainly derange the menstrual function than persistent constipation. =regularity important.=--every mother should make careful inquiry into the exact frequency of the menstrual period with her young daughter, at least during the first two years of the menstrual function. if there is pain at this time, then something is certainly wrong, and treatment should be taken at once. if there is irregularity, this also requires most prompt attention, as it will surely develop into something serious sooner or later. if the flow is too free, or not free enough, or if there is any deviation from the standard of health, the mother should be acquainted with it, and should proceed at once to correct the difficulty. =first two years very important.=--if a girl can get through the first two years of her menstrual life without serious disease, she stands a very good chance of enjoying good health during the rest of her life; while a slight mistake at this time may produce the most serious disease in later life. if you do not understand your ailments write to mrs. pinkham, lynn, mass. her advice is free and always helpful. chapter vii. disorders of menstruation. =amenorrhoea.=--this is a condition in which the monthly flow is suspended. it can hardly be called a disease, as it is rather a symptom of some disorder of the uterus, or of some constitutional defect. this may occur at the time when menstruation should normally appear, namely, from fourteen to fifteen years of age. =danger of a decline.=--if the young girl does not menstruate at sixteen, seventeen, or eighteen, something is certainly wrong, and treatment should be taken at once in order to correct the difficulty before the girl goes into a decline. it is not wise to trust too much to nature in these cases. such girls are generally thin and pale, with a peculiar sallow, or yellowish-green color to the skin which has given rise to the term "green-sickness," or "chlorosis." they fall easy victims to scrofula, consumption, nervous prostration, insomnia, and other diseases. =treatment.=--when the time for menstruation arrives, and the flow does not appear, the mother should give her daughter regular doses of lydia e. pinkham's vegetable compound. this remedy acts strictly according to the laws of nature, and simply brings about natural conditions. for some reason nature may not succeed in beginning this important change in the girl's life, but with the help that comes from the vegetable compound, this is sure to come to pass. =how lydia e. pinkham's vegetable compound acts.=--a better circulation is established, the condition of the blood is improved, the nervous system is greatly invigorated, and, as a result, the menstrual flow is established. this should set at rest a great deal of worry on the part of the mother, and it means a great deal to the daughter, as well. now, the mother can be assured that one great danger is passed, and, with proper care and attention, there need be no more trouble. lydia e. pinkham's vegetable compound, however, should be taken for some weeks or months until the habit is well established and menstruation appears regularly every twenty-eight days. =delicate girls.=--if the young girl menstruates, and yet is not in good health, then she should certainly take the vegetable compound for a week before the time when menstruation is expected; the great object being to establish regularity in the menstrual function. =keep the bowels regular.=--in all these cases attention should be given to the condition of the bowels, which are usually constipated. to correct this, the girl should take laxative doses of lydia e. pinkham's liver pills, just enough each night so that there may be one good, natural movement the day following. =look well to the diet.=--a great deal can be done, also, in the way of diet. girls, especially at this time, have a most perverted appetite, preferring pickles, olives, rich pies and cakes, and other indigestible foods. these are all bad, of course, as they disturb the digestion and keep the blood thin. let the diet consist principally of rich milk, eggs, lamb chops, beefsteak, chicken, and good bread and butter. if the milk rests heavy on the stomach, then add a tablespoonful of lime water to each glass of milk. daily exercise in the open air is also of value, and the sleeping-room should be well ventilated, especially at night. =menstruation suspended during pregnancy.=--during pregnancy menstruation is usually suspended, although the regular monthly flow may continue for two or three months. of course, suspension at this time is natural, and nothing should be done to bring on the flow. if menstruation appears when there is a strong probability that pregnancy exists, then the person should remain quietly in bed and eat only light food, and every precaution should be taken lest a miscarriage be brought on. =should a mother nurse her child while menstruating?=--menstruation is also usually suspended during nursing, although not infrequently this function is resumed again three or four months after childbirth. the question here arises whether the mother should continue to nurse her child while menstruating. if the child remains healthy, keeps steadily gaining in weight, and seems to be well nourished, and if the mother is not losing ground in any way, then there is no reason why the mother should not keep on nursing her child. if, however, the mother's health fails, or if there is evidence that the child is not prospering, then weaning should take place. as a rule, a menstruating mother does not have good milk for her child; it is usually thin and watery; although, as i have said, under certain conditions nursing may continue. =sudden suppression.=--sudden suppression of menstruation is most generally due to a cold, mental shock, or undue exposure of some kind. it is always accompanied with pain in the back, headache, more or less fever, and other unpleasant symptoms. it should generally be considered as a dangerous condition, and every effort should be made to restore the menstrual function. sometimes when menstruation is suddenly suppressed in this way, a so-called "vicarious" menstruation occurs, and there is hemorrhage from the lungs, the nose, the gums, the bowels, or from some other source. =treatment of suppression.=--the treatment of sudden suppression consists of a hot foot-bath, or sitting in a tub of hot water. at the same time the person should drink a bowl of hot ginger tea, or hot lemonade, be covered well with blankets, and every effort be made to bring about a profuse sweating. then have the person go to bed, and apply hot cloths across the lower part of the bowels. place at the feet bottles of hot water, or hot bricks, and keep up the perspiration in this way for an hour or two. this is all that need be done in the great majority of cases. =only one medicine to be taken.=--as the shock to the system tends to disturb the menstrual function for some time to come, the person should begin at once with lydia e. pinkham's vegetable compound, and should continue it through the coming month, in order to insure that the next menstruation may be normal in every way. =scanty menstruation.=--often menstruation appears with perfect regularity and yet is greatly deficient in amount. as we have stated elsewhere, there is no rule about this, and yet when the menstrual function is scanty, it is almost invariably a symptom of anã¦mia, or poverty of the blood. =anã¦mic girls.=--such girls are listless, easily tired, nervous, with little appetite, poor digestion, and with no resistive power. by taking lydia e. pinkham's blood purifier regularly a most remarkable change is brought about; and by the use of an easily digested and very nourishing diet, as just given in this chapter, together with plenty of outdoor exercise, this condition can be corrected before serious trouble ensues. =dysmenorrhoea.=--this is better known as "painful menstruation." it is due to a large number of causes, and yet can almost invariably be relieved by proper treatment. =two great causes.=--in the great majority of cases the cause is two-fold: weakness of the nerves and congestion of the uterus. these are so closely allied that it is often quite impossible to tell which is the ruling factor; indeed, one seems to be largely dependent upon the other. it is certainly true that congestion of the uterus almost invariably produces neuralgia of different parts of the body; while nervous exhaustion, nervous prostration, neuralgia, and general nervousness often show themselves by this increased pain at the menstrual period. =symptoms of dysmenorrhoea.=--usually the most marked pain is before the flow is well established. the person has a heavy pain in the lower part of the bowels, with sharp, darting pains extending down the back of the limbs. then the pain becomes more concentrated in the uterus itself, or sometimes in an ovary at the side. the pain may begin as a dull, heavy ache, which gradually changes into a sharp, darting pain, and which culminates at last in distinct and positive attacks of uterine colic, or cramps. the person suffers such intense pain that a chill may be produced which is followed by a high fever. often the pains are of a bearing-down character, and are not unlike those in the last stages of ordinary labor. =often make a complete wreck.=--these attacks of uterine cramps tell severely on the general health of the person, and if they are allowed to continue without treatment, they almost invariably make a complete wreck of the constitution. =can be cured.=--this most distressing and most agonizing complaint may be quickly and entirely cured by a thorough course of treatment with lydia e. pinkham's vegetable compound. this remedy should be taken continuously; not a day should pass without the regular dose. =old cases cured.=--if the disease has existed for some time, it must not be expected that it can be cured in a month, but by perseverance the cure will certainly come and will be perfectly satisfactory. =a valuable aid.=--in the meantime, the person who suffers from painful menstruation, a day or two before menstruation is expected, should take lydia e. pinkham's vegetable compound, being careful to keep the bowels in good condition. =additional treatment.=--if possible, the person had better remain in bed, or recline upon a sofa, for at least a day before the expected menstruation, certainly as soon as the first uncomfortable symptoms appear. then have her take a hot foot-bath, get into bed and cover with warm blankets, with bags or bottles of hot water, or hot bricks at the feet and back, and with warm cloths over the lower part of the abdomen. =temporary relief.=--if the pain is exceedingly severe, and is not relieved by these simple measures, then wring out flannel cloths from as hot water as can be borne and place these over the lower part of the bowels, directly over the uterus, covering them with dry flannels. as soon as these become cool, change for hot cloths again, using care, of course, that the cloths be not hot enough to burn. it is often surprising what instant relief from pain this simple procedure will produce. =do not take opium.=--no one should think for a moment of taking opium in any form at these times, as the opium habit is very easily contracted and is almost impossible to break up. this is also true of other anodyne remedies. by carrying out the suggestions given above, it will be found that their use will not be necessary. =thousands of grateful letters.=--if the readers of this book could only see the thousands of letters from grateful women the world over telling how this vegetable compound relieved them from the fearful torture which they had been enduring for years once a month, they would use every endeavor possible to spread the good news to every suffering friend that at last there is a perfect and absolute cure for this most distressing and most frightful complaint. =reasons for these startling cures.=--the reason why lydia e. pinkham's vegetable compound works so admirably in these cases is easily understood when we call to mind the fact that some of its ingredients are the strongest of nerve tonics, building up, strengthening, and giving tone to the whole nervous system; while other ingredients have the remarkable property of relieving congestion of all the female generative organs. =to illustrate "congestion."=--if a string be tied around the base of the finger snugly, but not too tightly, the finger soon becomes darkened from the obstructed circulation. we say the finger is "congested." all that has to be done, in this case, is to cut the string and the congestion is promptly relieved. =cures congestion.=--in cases of congestion of the uterus, lydia e. pinkham's vegetable compound removes obstruction to the circulation as effectually as cutting the string relieves the congestion of the finger. when the circulation is perfectly natural through these parts, then the congestion and inflammation must disappear and the uterus itself must again resume its natural position. =menorrhagia.=--this is better known as "profuse menstruation." just what constitutes an unnatural loss of blood cannot be stated, as each woman is a rule to herself. from experience she knows just about what is the normal amount she should lose each month and retain her health and strength. when this amount is more than natural, especially when sufficient to produce weakness and prostration, then it becomes "profuse." =occurs in the full-blooded.=--profuse menstruation may occur in those who are very full-blooded, or in those who are extremely weak and pale. when occurring in the former, the person usually complains of a dull, heavy, throbbing headache, pain in the back, and other symptoms of fever. such persons recover from an excessive flow of blood quite promptly, and do not suffer severely from it. =occurs in the pale.=--on the other hand, when this condition occurs in those who are very weak, pale, and thin, there is usually great prostration, which may even become most alarming. =treatment for the former.=--when profuse menstruation occurs in those who are full-blooded, the diet should be quite simple and plain. indeed, it would be better if the person should take but two meals a day and should eat but little or no meat. immediately upon the appearance of menstruation she should go to bed and remain there as quiet as possible, for in this way the pain and fever will be less and the amount of the flow greatly diminished. =treatment when pale and debilitated.=--it is a much more serious matter when this excessive loss occurs in those who are pale and debilitated. often the most energetic measures are necessary even to preserve life itself. the following rule should be observed when possible:--just as soon as menstruation appears, the person should go to bed and remain there quietly until the flow is nearly over. of course it is an easy matter to give these directions, and exceedingly hard, often quite impossible, for them to be carried out. many women have work that must be done, or children who must be cared for during these days just as well as any other time, and it is almost out of the question for them to remain quiet. yet the question seems to be whether they will remain in bed two or three days at this time, and then have far better health for the rest of the month, or whether they will drag along through all the month. we would certainly urge that this suggestion be carried out as often as possible, and that for one or two days the person keep as quietly in bed as possible. =when very excessive.=--if the flow is very free, then the foot of the bed may be raised three or four inches by placing blocks of wood under each lower corner. this will tend to check the flow. =wonderful cures possible.=--lydia e. pinkham's vegetable compound has made some most startling and almost miraculous cures in just these conditions. an immense number of letters are on file from women who have despaired of relief, given up all hope, and who were confirmed invalids until after taking this famous remedy. its continued use heals the inflammation in the cavity of the uterus, causes a better circulation through that organ, makes the blood richer, strengthens the digestion, and thus greatly improves the general health. =relief is prompt.=--the very next month after beginning its use the flow is diminished, the next month it is still less, and so on, until soon there is only a regular, natural menstruation. =a happy change.=--and what a change this means to suffering women! it means new life, new hope, new ambition, new courage. it means work better done, children better cared for, and all social and domestic duties better performed. i am indeed most happy in being able to tell suffering women what prompt relief lydia e. pinkham's vegetable compound is sure to bring them. in these cases i always recommend the use of the vegetable compound in the form of lozenges, or pills. =metrorrhagia.=--when there is great loss of blood at other times than during the menstrual period, it is given the technical name of metrorrhagia. it means "uterine hemorrhage." keep the person quietly in bed, and have the foot of the bed raised as suggested above. if the hemorrhage is at all severe, a physician should be summoned in order that a careful examination may be made and the cause of this unusual occurrence thoroughly understood. =if you do not understand your ailments write to mrs. pinkham, lynn, mass. her advice is free and always helpful.= all such letters are strictly confidential; only women assist her in answering them. chapter viii. diseases of the uterus and ovaries. =inflammation of the uterus.=--inflammation of the uterus may be either acute or chronic. when acute, as following an abortion, taking cold during menstruation, etc., there is considerable fever, pain in the lower part of the bowels, nausea, and sometimes vomiting, tenderness on pressure over the uterus, pain when passing the urine and general discomfort. =treatment of the acute form.=--the treatment consists in having the person remain quietly in bed, applying bottles of hot water to the feet, if they are cold, and keeping cool cloths over the head if hot from the fever. in this way the circulation may be better balanced, and the tendency to congestion relieved. then take a flannel cloth about six inches square, dip it in hot water, and wring as dry as possible with the hands; now sprinkle ordinary spirits of turpentine freely over one side, and place this side directly over the centre of the lower part of the bowels, that is, just over the uterus. cover this flannel with another warm, dry flannel, and allow it to remain on until the smarting is quite pronounced, or the skin red. then remove this, and apply hot cloths wrung from hot water. use the turpentine cloth again in four or six hours, if the tenderness and pain still persist. =only one medicine needed.=--begin at once with lydia e. pinkham's vegetable compound, in order that the attack may be cut short. this the compound will certainly do if taken faithfully according to directions. after the acute attack is over, if there is any constipation, this should be relieved by lydia e. pinkham's liver pills; and if there is any discharge from the uterus, lydia e. pinkham's sanative wash should be used once or twice each day, in order to hasten recovery all that is possible. =chronic inflammation.=--it is not exaggerating in the least to say that probably 75 out of every 100 women in the world have more or less chronic inflammation of the uterus. =causes.=--the causes of this are many, as improper dress, which constricts the waist, and presses down upon the delicate organs in the pelvis; improper attention to the health at each menstruation; over-work; anxiety; miscarriages; unskillful treatment at childbirth, etc. =lives of suffering and sorrow.=--what miserable lives women have to endure who go about from day to day with a chronic inflammation of the uterus. each hour there is that dragging, pulling, bearing-down pain; that heavy weight; that terrible depression; and that feeling of abandoned hope. yet hundreds of thousands, i might say millions of women have had all this suffering and sadness turned to joy and comfort, simply by taking lydia e. pinkham's vegetable compound. =stories almost beyond belief.=--the stories received from our friends seem almost beyond belief. the most striking of them cannot be printed because i fear my readers would think such cures were quite impossible. the letters tell as terrible stories, as frightful conditions as could possibly exist, and yet all this has quickly and promptly changed to robust health by the use of lydia e. pinkham's vegetable compound. so often has this been reported that there is not the least room for doubt. =i speak positively.=--i am not guessing in this matter; it is altogether too serious; there is too much at stake. so i urge upon you to give lydia e. pinkham's vegetable compound a thorough trial, feeling positive, without the slightest question of a doubt, that you will be quickly and permanently cured. =leucorrhoea.=--this is also known as "the whites, or the female weakness." it is a symptom of inflammation of the uterus; and that this disease is so prevalent is again proved by this almost universal ailment among women. it is characterized by a white discharge from the vagina which often becomes very irritating, and is especially bad just before or after menstruation. it is a symptom that should not be allowed to go untreated, for it shows that there is serious trouble which may bring about an incurable condition. yet when properly treated, it may be quickly remedied, and all danger removed. =treatment.=--first of all, it is necessary to remove the inflammation that exists in the uterus itself. this is done by the persistent use of lydia e. pinkham's vegetable compound. as i have described elsewhere, this will remove all congestion, heal the inflammation, and bring about a healthy circulation. for this i strongly recommend that lydia e. pinkham's sanative wash be also used with a syringe for local treatment.[1] this should be used each night as a vaginal injection, according to directions, thus thoroughly cleansing the parts, and entirely relieving all irritation which these acrid secretions are sure to set up. if this discharge has been irritating enough to cause any chafing, eruption, itching, or uncomfortable sensation of any kind about the external parts, then the sanative wash should be used for bathing the parts; the relief will be immediate, and the cure very prompt. =may be quickly cured.=--i speak with great positiveness here, because of vast experience and because of the universal success of this treatment. i do not believe there is a case of leucorrhoea which cannot be relieved and soon permanently cured by this treatment. there is no delay; relief comes at once. a great improvement in all the symptoms is very marked, even after the second or third day of treatment. =neglect causes ulceration.=--i would add a word of caution here to women who are afflicted in this way, as the retention of these discharges is likely to produce an irritation about the mouth of the uterus which will result in serious ulceration, and even be the means of producing the most serious and most incurable diseases. =ulcers on the uterus.=--because of the low condition of the system, thin blood, and the local inflammation in the uterus itself, ulcers may form about the mouth of the uterus. these are accompanied by more or less pain, a sense of heaviness and weight in the lower part of the bowels, and a whitish discharge similar to that of leucorrhoea only frequently streaked, or tinted, with blood. the discharge continues about the same all through the month between the days of menstruation. this condition should have the same treatment as that mentioned above for leucorrhoea, and the recovery will be equally prompt. =early treatment necessary.=--if women only understood better how easy a matter it is for these ulcerations to widen and deepen until some incurable and terrible disease results, they would be more prompt in taking treatment, especially when this is sure to be followed by a perfect cure. when the blood is thin and poor, and when the weight is reduced, lydia e. pinkham's blood purifier should be used regularly. the blood purifier, the vegetable compound, and the sanative wash, have done as great work in preventing serious disease as in curing it. =displacement of the uterus forward.=--the uterus may be displaced either forward, backward, or downward. by referring to the illustration in the first part of this book, it will be noticed that the uterus naturally tips slightly forward, so that when it is displaced forward, the condition is simply an exaggeration of its natural state. =causes bladder trouble.=--by referring to this illustration again, it is at once apparent that this tipping forward must bring about some difficulty with the bladder, and such is the case. the most marked symptom is painful and frequent passing of the urine, with a dull and heavy pain across the lower part of the bowels. often this weight is so increased by walking that the person can be upon the feet only a short time without causing discomfort and pain. this condition may be brought about by some unusual effort at lifting, jumping, or straining, or especially by wearing too tight clothing about the waist, tight lacing being probably the most frequent cause of all. =the cure.=--the general treatment here consists in taking a thorough course of treatment with lydia e. pinkham's vegetable compound, in order to strengthen the ligaments of the uterus which hold this organ in place. when the condition of the system is improved, the nerves strengthened, and the blood made more rich by the use of this compound, then these ligaments partake of this general improvement, and by becoming more tense, bring the uterus back into position. =displacement backwards.=--the uterus may be tipped backward, in which case it will rest against the lower bowel. the principal symptom here is pain in the lower part of the back, as if a movement of the bowels were necessary. there is great discomfort in walking, because of this sense of pressure. the pain is always increased when the bowels move, and is associated with a sense of obstruction, and painful menstruation is very common. =the treatment.=--here the same treatment should be followed as mentioned for the opposite condition above. in the first place, the bowels should be kept in good condition by the use of lydia e. pinkham's liver pills, taking these in just sufficient amount to cause a free movement of the bowels daily. then thorough and prolonged treatment with mrs. pinkham's vegetable compound will give such strength and tone to the ligaments about the uterus that they will again bring back this organ to its proper position. =falling of the womb.=--the most distressing of all these displacements is that known as "prolapsus, or falling of the womb." the most frequent cause of this condition is complete relaxation of the ligaments which naturally support this organ. when the ligaments become weak, they easily stretch, and thus allow the uterus to fall down into the vaginal canal, even nearly to the surface of the body. =symptoms.=--this displacement causes irritation of the bladder and lower bowel, discomfort in walking, painful menstruation, leucorrhoea, a dragging pain in the back, and most marked bearing-down pain in the lower part of the body. =the cure is certain.=--the treatment of this most distressing affection is usually followed by prompt and permanent results. lydia e. pinkham's vegetable compound should always be taken, because of its great power to relieve all inflammation and give strength and tone to the ligaments which hold up the uterus. lydia e. pinkham's sanative wash should be used, also, for its cleansing and strengthening properties, on the local parts. if a sitz bath-tub is in the house it may be used to great advantage in these cases. a single pail of water will be sufficient, and should be as hot as can be comfortably borne. if a tub of this kind is not at hand, then an ordinary bath-tub may be used, having in it sufficient water to come well over the hips when the person sits in it. =the one permanent cure.=--by taking lydia e. pinkham's vegetable compound, these relaxed ligaments are given strength and tone so that they assume their former power. as they gain strength they contract, pulling the uterus up into its natural position, and holding it there permanently. i can most positively assure every woman who is suffering from all the discomfort and terrible distress which always accompany falling of the womb, that she may be promptly and most perfectly cured if she will only follow my advice. =an abundance of proof.=--so many letters have come from women who have suffered and have been cured that it is not possible for a reasonable person to doubt what they say. i can only urge all affected with these complaints to give lydia f. pinkham's vegetable compound a good trial, feeling perfectly assured that they will be abundantly satisfied in every way. if you do not understand your ailments write to mrs. pinkham, lynn, mass. her advice is free and always helpful. such letters are strictly confidential communications from one woman to another who will never betray the confidence. footnote: [1] every woman suffering from uterine or vaginal troubles should own and use a syringe. i would recommend the use of ruth paxton's improved fountain syringe. i believe it is the only one that will convey the solution to every part of the vaginal cavity. the ordinary syringe is inadequate. it can be obtained by sending to the r. paxton company, 221 columbus ave., boston, mass. price $1.75, postpaid--registered letter or postal note. it will repay you a thousand times to take the trouble to send for it, as the recoveries from disease are quicker when it is used. anyway, send two-cent stamp for her little book of information. you will see by the letters it contains how the syringe is regarded by those who are using it. chapter ix. diseases of uterus and ovaries (continued). =ovaries, congestion of.=--this disease usually comes from taking cold during menstruation, from some injury, extra strain during lifting, or from some slow inflammatory process. the symptoms are pain and tenderness in one or both sides of the lower part of the body. there is more or less continuous pain, which is always worse in standing or walking. the tenderness in the sides is increased during menstruation, especially if pressure be made over the part. sometimes the pain is quite severe when the bowels move. there is always a feeling of distress, frequently associated with nausea, and often more or less fever. =treatment.=--for treatment the person should have as good surroundings as possible, and should take complete rest during menstruation. in order to relieve the congestion in these parts and thoroughly control the pain, lydia e. pinkham's vegetable compound should be taken at once. =removal of ovaries.=--this condition of the ovaries gave rise to the practice of removing these organs. just as soon as a woman consulted a physician and complained of tenderness over the ovaries, he was sure to advise her to have these organs removed. =less operating than formerly.=--but this practice is rapidly passing away, and the very surgeons who were so anxious to operate a few years ago are now found advising against it. this is because of the serious results which follow this operation. while the pain and tenderness in these parts would be relieved, yet the profound and overwhelming impression made upon the nervous system, by producing such a remarkable change in the life of the woman, was even worse than the disease itself. =results of removal of ovaries.=--women who have had their ovaries removed are frequently the victims of hysteria, melancholia, extreme nervous prostration, insomnia, and other distressing and dangerous complaints. =surgical operations unnecessary.=--then, again, it is becoming well known over the whole country that lydia e. pinkham's vegetable compound can relieve congestion and pain so thoroughly that the surgeon's knife is unnecessary. i am so confident in this belief that it hardly seems possible that any woman would continue to suffer in this way, when it is so useless. i know we can make every woman perfectly comfortable and at rest, no matter how long she may have suffered, if she will only follow our simple directions. =the one certain cure.=--all she has to do is to keep her bowels in good condition by taking lydia e. pinkham's liver pills, and at the same time take a thorough course of treatment with the vegetable compound. if you have any friends or neighbors who are suffering from this disease, and who fear that it will lead to ovarian tumors, which must ultimately necessitate a dangerous surgical operation, i urge upon you to tell them the story of this vegetable compound. =always brings good cheer.=--it has brought happiness to so many homes, has relieved so much suffering, and has cheered and comforted so many thousands of women, that i am sure you will be doing a great deed of charity if you will only aid in spreading this glad news. =tumors of the uterus.=--the uterus is subject to tumors, or growths, the symptoms of which are much like those of chronic inflammation. as a rule, the person suffering from these tumors knows nothing whatever of their existence until some competent physician has told her such is the case. =fibroid tumors.=--the most common tumors are known as fibroids. they are often small, and yet sometimes attain a considerable size. until within a few years surgeons were always anxious to operate upon these tumors; but this is now largely done away with, for they are not fatal in themselves, and only become serious when they attain an exceedingly large size, or, what is more frequently the case, cause excessive flowing during or between the menstrual periods. =tumors cured without the knife.=--in these cases lydia e. pinkham's vegetable compound shows its remarkable power to great advantage. by establishing a better circulation through the uterus, and relieving the congestion in the surrounding parts, and by giving strength and tone to the smaller blood-vessels, the hemorrhage is controlled and the inflammation is reduced. the tumors cease to grow, diminish in size, and disappear altogether under its influence. =vagina, inflammation of.=--occasionally there is an acute and most intense inflammation of the vagina caused by exposure to cold, irritating discharges from the womb, the use of pessaries, supporters, or some contagious disease. many women suffer from this complaint towards the close of menstruation, when the discharges are acrid and most irritating. =promptly cured.=--this inflammation can be promptly cured by the frequent use of lydia e. pinkham's sanative wash. prepare this strictly according to the directions on each package, and use it as a vaginal injection two or three times a day. the cure will be hastened by employing a sitz-bath (sitting in a tub of hot water, or in a bath-tub). =to prevent extension of disease.=--in order to prevent the inflammation from extending into the uterus, it is always wise to take lydia e. pinkham's vegetable compound for a few days after an attack of this kind. =pruritus, itching.=--pruritus, or itching of the external parts, is a most annoying affection, which often renders life itself almost unendurable. its most frequent cause is due to irritating discharges from the uterus or vagina. quite a large per cent of the women who are passing through the "change of life" are troubled in this way. it is also a marked symptom of diabetes, or "sugar in the urine;" and if the itching is associated with an unusually large flow of urine, together with dryness of the mouth and extreme thirst, there is a probability that the person is suffering from diabetes. in such a case a specimen of the urine should be taken to a competent physician, and he should be asked to make a thorough examination of it in order to definitely determine this point. =treatment.=--the treatment of pruritus consists in keeping the parts thoroughly cleansed by frequent vaginal injections of lydia e. pinkham's sanative wash, even three or four injections daily; and also bathing the external parts with the same solution. =can be promptly controlled.=--although medical writers so generally claim that this disease is almost impossible to relieve, and although they recommend the application of severe caustics, yet i have never found any difficulty in promptly controlling and curing this affection by the faithful and persistent use of lydia e. pinkham's sanative wash as a local application and the vegetable compound for its constitutional effects. =constitutional treatment necessary.=--although this disease shows itself in only one place, yet the difficulty is in the whole system, and can only be thoroughly removed by the internal use of lydia e. pinkham's vegetable compound. thousands of letters from women tell that their life of agony, distress, and sleeplessness was changed to one of perfect comfort almost immediately upon the use of these remedies. =bladder, inflammation of.=--sometimes the inflammation of the vagina and uterus is so severe that it involves the bladder; or an irritable condition of the bladder may be produced by a pregnant uterus pressing forward against it; or the uterus may be tipped forward a trifle more than natural, and thus press against the bladder sufficient to cause irritation. =symptoms.=--the principal symptom of congestion or inflammation of the bladder is a frequent desire to pass the urine. this act is almost always painful, and is sometimes accompanied with spasmodic contractions of the walls of the bladder, causing severe straining. =may become chronic.=--if treatment be neglected, this condition easily becomes chronic, when it is very difficult to cure. prompt treatment in these cases is strongly urged because it can be cured in every instance, and thus an immense amount of suffering avoided. =treatment.=--if possible, the person should remain in bed or recline on a couch. the diet should consist largely of liquids, nothing being better than good milk. meats, rich soups, and all pastries should be avoided. mrs. pinkham's vegetable compound should be taken at once, because of its most happy effect in relieving congestion and inflammation of all the pelvic organs. indeed, here is one instance where the vegetable compound is alike useful to both sexes. the most flattering testimonials have come from men who have tried this remedy "because it was in the house," and who were most happily surprised to find that the relief was prompt and the cure speedy. for all irritable conditions of the bladder, whether of recent or old standing, i do not believe there is a remedy in the world that holds out such great promises of complete relief equal to lydia e. pinkham's vegetable compound. =the menopause, or "change of life."=--this is a cessation of menstruation. it usually occurs between the ages of forty and fifty years, although frequently before and even after this time. =symptoms.=--the person first notices that although menstruation had previously been regular, yet now it has become irregular, not appearing more frequently than once every six weeks or two months; or possibly passing over a month, and then appearing regularly again for the following two or three months; or the flow may be less and less month after month, until gradually it disappears altogether; or, not infrequently, menstruation ceases abruptly, without any warning whatever. =a natural condition.=--the change of life should be a perfectly natural condition, not associated with any unpleasant symptom whatever. yet this is rarely the case, while often the suffering at this time is most intense in every way. =affects nervous system.=--the most severe effects are frequently produced on the nervous system. these are known as "heat flashes." it is a marked symptom with a great many women, and is described as a sensation of waves of heat passing over the body. sometimes these are very severe, causing the face to become very red, producing dizziness and intense headache. often there is melancholia, great depression, and not infrequently complete prostration of the nervous system. the digestion may be disturbed, producing constipation, diarrhoea, dyspepsia, loss of appetite, offensive breath, biliousness, etc. most marked changes are certainly taking place in the whole system, and it is but natural that every part of the body should be profoundly impressed. =not expensive treatment.=--i cannot urge too strongly upon my readers the necessity of their taking lydia e. pinkham's vegetable compound all through these remarkable changes. it is not a great expense to take this vegetable compound in moderate doses four times a day for weeks, or even months, during these changes. =a critical time.=--if this period of life be passed over in safety, then there may be years and years of robust health remaining; while if it be not attended to properly, the remainder of the life may be one prolonged day of agony. even when persons have suffered during all their menstrual life, they can now have perhaps a score or more of years of complete relief if they properly care for themselves during this change. =keep under its influence.=--lydia e. pinkham's vegetable compound is a great tonic in itself, bracing up the whole nervous system, aiding digestion, and causing all the forces of the body to act more in accord with nature. then it has a special influence over the uterus and ovaries; indeed, so marked is its power to correct disease that all the trying days of the "change of life" may be passed over in perfect safety, if only the system be continuously kept under its influence. =may be made easy and natural.=--women who have been dreading this change, and who have been made to look upon it as something horrible to pass through, may now lay all such anxiety aside, for mrs. pinkham long ago solved the problem of making this time of life as healthy and natural as any other. it is not claiming too much to say that if women everywhere will only take lydia e. pinkham's vegetable compound through this trying time, they will come out of it feeling better in every way than they have felt for many years. =if you do not understand your ailments, write to mrs. pinkham, lynn, mass. her advice is free and always helpful. such letters are strictly confidential and answered with the help of women only.= chapter x. pregnancy, its symptoms, diseases, etc. =sometimes difficult to tell.=--even the most skilled physicians sometimes make mistakes in stating that pregnancy exists when it does not. =the first sign.=--the most valuable and striking sign of pregnancy is the cessation of the monthly periods; yet even this is not always reliable. sometimes menstruation continues for three or four months, especially during the first pregnancy, although this is exceedingly rare. as a rule, to which there is hardly an exception, if menstruation ceases in a married woman who has previously been regular, she is, in all probability, pregnant. =other signs.=--another important sign is the enlargement of the abdomen, although this cannot be detected much before the fourth month. a valuable sign, also, is the enlargement of the breasts, with a widening and browning of the pink ring around the nipples. enlargement of the breasts often begins as early as the second month, and is quite marked by the fourth or fifth month. =morning sickness.=--morning sickness is a symptom present in the majority of cases. it usually consists of a marked nausea upon rising, and perhaps vomiting. this may last only a few hours in the early morning, or continue through the greater part of the day. it generally appears in the second month and lasts only through the third month, although, in bad cases, it may continue through the whole period, and very seriously affect the health. =treatment.=--there are any number of remedies recommended for the treatment of this morning sickness. what will cure one case seems to be perfectly useless in another. it has been my experience that the best way to manage these cases is as follows: have the person take a slice of toasted bread, or a toasted cracker, with a little coffee if desired, while in bed, remaining there at least half an hour after eating. or, the person may take a glass of milk to which two tablespoonfuls of lime water have been added. then, by rising slowly and moving about carefully, it is often possible to go through the day without any sickness whatever. i have known many cases to be entirely relieved by eating a little ordinary pop-corn. =the morning meal.=--the morning meal may consist of milk to which a little lime water has been added; or a poached or soft-boiled egg. sometimes scarped beef, lean and rare, salted and spread on very thin bread, quiets the stomach at once, while it is highly nourishing. =only one medicine needed.=--it is surprising what happy changes lydia e. pinkham's vegetable compound brings about in this condition. the irritability subsides, the digestion is greatly improved, the nervous system is strengthened, and all these uncomfortable and disagreeable symptoms pass away. the compound should be taken in small doses three times a day, after meals. =a bandage may relieve nausea.=--an abdominal bandage will sometimes relieve the morning sickness, if placed snugly, but not too tightly, about the body. it need be worn only a week or two, for a trial, and should always be taken off at night. if the nausea persists during the day, then let the food be light and taken in small amounts, at frequent intervals. ="quickening."=--this is another sign of pregnancy. the word refers to the detection by the mother of the movements of the child. although, without doubt, the child moves within the mother at a much earlier period, yet these movements are too feeble to be noticed until pregnancy has advanced four or four and a half months. =other symptoms of pregnancy.=--other symptoms are morbid longings for unusual articles of food, as sour apples, vinegar, charcoal, clay, slate pencils, etc. these longings, however, should not be satisfied, as they do not represent the demand of nature for these substances. they belong to the same class of changes which are shown by a marked difference in the disposition of a person whereby the lively and cheerful woman becomes melancholy, gloomy, and irritable. =diet during pregnancy.=--the diet during the whole of pregnancy should be generous, yet easily digestible. a great many women do not change their diet at all, and if the person is in good health and does not suffer in any way, there is no reason whatever why the diet should be changed, unless the evening meal be made somewhat lighter. =eat sparingly of meat.=--it is always wise not to eat meat more than once a day. this is because a meat diet throws more work upon the kidneys, and any failure of the kidneys increases the probability of serious trouble at childbirth. so far as is known, there is no foundation for the belief that any special article of diet has any particular effect upon the development of the child. =care of the breasts.=--the care of the breasts during pregnancy must be commenced early. all pressure of the clothing should be removed, in order to give them full opportunity to develop. they should be kept warm, however, and well supported, if the size renders them uncomfortable. =mothers should nurse their children.=--statistics show that the summer diarrhoeas and dysenteries, which carry off such immense numbers of children each year, are almost unknown among babies that nurse. it is the artificially fed child which suffers from wasting diseases and disturbances of the digestion which are so fatal to life. therefore, every prospective mother should do everything in her power to prepare for the proper nursing of her child. =care of the nipples.=--if the nipples are flat, they can be pulled out gently each day with the fingers, and thus the difficulty entirely remedied. at the beginning of the last month of pregnancy, the nipples should be hardened in order that nursing may be painless, and that all fissures, or cracks, may be avoided. every morning and night apply the following solution to the nipples with a piece of absorbent cotton:- glycerite of tannin, 1 fluid ounce. water, 1 fluid ounce. allow this to remain on the nipple. this cannot be used after confinement, for the bitter taste would be objectionable to the child. =can sex be foretold?=--mothers often wish to know if it is possible to determine the sex of the child before it is born. although a great deal has been written on this subject, and a number of so-called rules have been made, yet it is absolutely impossible to tell whether the child will be a boy or a girl; and it is also equally impossible to do anything that could in any way exert an influence in producing a child of the desired sex. =to tell time of confinement.=--for two hundred and eighty days, or forty weeks, the prospective mother has been conducting herself in the best way she thought possible, that all good might be exerted upon the new life. the question now comes, when may the day of confinement be expected? i give here a table for calculating this day, which i am sure will be found very convenient. obstetrical table. --------+--------------------------------------------- january | 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 oct'r | 8 9 10 11 12 13 14 15

is the average. the table presents at a glance the beginning and end of 280 days for every day in the year. find the date of menstruation in the upper line of the horizontal column, and the figure below, with the corresponding month, will indicate 280 days. =to avoid miscarriage.=--the pregnant woman must be very careful as the usual time for menstruation approaches. it is then that any undue effort, unusual lifting, excessive grief, or shock to the system, may bring on a miscarriage. this is especially true if such a misfortune has previously occurred. =a great preventive.=--the most abundant testimony shows that lydia e. pinkham's vegetable compound is an almost certain preventive to miscarriage or abortion. it gives strength to the uterine walls, quiets the first approach of pain, controls any spasmodic contractions, and brings about such a healthy condition that all danger is averted. i cannot speak too strongly of this vegetable compound for these cases. so many mothers have written us that they are now happy in the possession of a child, when, for time and time again, they would have a miscarriage at the third or fourth month. =keep it in the house.=--every pregnant woman should always keep in the house a bottle of lydia e. pinkham's vegetable compound. she does not know the day when she will need it, and when that day comes she will require it promptly. at any time when there is soreness, tenderness, unusual pain, any unnatural discharge, or any symptom whatever that shows pregnancy is not pursuing a perfectly natural course, she should begin to use the vegetable compound at once. it should be taken in small doses two or three times a day, just enough to produce its strengthening, quieting, and healing effects. if she finds she has been overdoing, has strained herself in any way, or fears that some unfortunate result will follow an extra hard day's labor, let her take a few doses of lydia e. pinkham's vegetable compound as a certain preventive to future trouble. =the one universal cure.=--in other words, i repeat what i have already said so many times, that whenever there is trouble of any kind with any part of the female generative organs, whenever these do not act in a perfectly natural manner, then the lydia e. pinkham vegetable compound is indicated; for it is the one great, universal and never-failing cure for all the affections which fall to the lot of womankind. =makes mother and child strong.=--many thousands of wives owe the fact that they are mothers to-day to this grand remedy, and thousands upon thousands of children are happy, strong and robust because their mothers were wise enough to use it. keep it in the house. do not be a day without it. have it where you can reach it at any time. put your confidence in it. 'twill prove a never-failing friend to you in time of need. =mothers' marks.=--there is a wide belief among women that any strong impression made at a certain time during pregnancy will exert a powerful influence in producing some defect or deformity in the child. the opposite is also held, to the effect that beautiful objects, delightful music, and everything elevating and ennobling will have a favorable effect upon the body or mind of the child. an immense amount of testimony can be produced on both sides of this question. the weight of evidence, however, is rather in favor of these so-called "maternal impressions." in other words, it seems possible that under very unusual conditions the mother may affect her unborn child because of some powerful impression made upon the system. yet hundreds of thousands of mothers become frightened and undergo the most terrible experiences without having the slightest unfavorable effect upon the child; while other mothers give birth to deformed children when they have been surrounded with every comfort and have not been disturbed in any way. no one understands this subject, and but little can truly be said about it. =hereditary influences are strong.=--on the other hand, we all know how strong is heredity. therefore it is only acting the part of ordinary wisdom for every pregnant woman to avoid all disagreeable things possible and cultivate everything that is good and true. =early training necessary.=--when we come to study the theory of heredity, we see that it is impossible for any mother to completely change her course of life simply during pregnancy and have a corresponding effect upon her child. to produce the best results on the offspring it is necessary that the mother should have cultivated her own mind and body through many years of training. =were cured early in life.=--lydia e. pinkham's vegetable compound has done untold good to the present generation. there are hundreds of thousands of children living to-day who are healthy and happy because years before they were born their mothers, when young girls, took this grand household medicine. they were restored to health, a great load was lifted, and things again looked cheerful and bright, and in this condition a happy baby was born into the world. =if you do not understand your ailments write to mrs. pinkham, lynn, mass. her advice is free and always helpful. such letters are strictly confidential and answered with the help of women only.= chapter xi. problems in nursing. =diet during nursing.=--many mothers believe that it is necessary to eat only certain articles of diet while nursing their baby, for fear the child may be given the colic. while this may be true in certain cases, yet it is the exception. as a rule, mothers may eat nearly everything digestible without fear of affecting the baby. =exceptions.=--sometimes raw fruits or acid substances may change the milk in some way so that it will disagree with the baby, but as i have said, this is not the rule. occasionally, however, when such articles of diet as onions, cauliflower, and cabbage have been eaten, these will impart such an odor and taste to the milk that the child will refuse to nurse. =must be guided by experience.=--the only precaution the mother need take is that if she finds some article of diet disagrees with her, or if she knows a certain article always causes pain or discomfort in the child, then these should be avoided. it is true that certain medicines, especially purgatives, may be taken by the mother which will affect the child very quickly. here the same rule should be the guide as should always govern one, namely, no article of diet should be used which is known to disturb the digestion. =insufficient supply of milk.=--when a mother knows that the chances of her child's life are greatly increased if it has its natural food, she will certainly make unusual efforts to supply all the food necessary. mothers are too likely to think that an increase in the quantity of the milk answers every purpose; but this is of no use unless the quality is increased as well. the free use of soups and some malt extracts may increase the quantity, but this does the child no good. it too much resembles the example of the milk-man who uses the well-pump to increase his supply of milk. =how increased.=--however, the supply of milk can easily be increased in quantity and correspondingly improved in quality if the mother will drink freely of cow's milk, and use other substantial foods at the same time. if the milk is constipating, or rests heavy on the stomach, then a little lime water may be added to it in the proportion of one or two tablespoonfuls to a glass of milk. regular exercise in the open air is also necessary in order that the general health may be kept in the best possible condition. =anger may poison milk.=--it is a fact that if the child nurses after the mother has had a severe fright, or has become violently angry, the milk will sometimes act as an intense poison. in such cases the mother had better empty the breasts with a breast-pump, and not nurse the child for ten or twelve hours afterward, substituting some artificially prepared food. =extra supply of milk.=--sometimes the secretion of milk is so great that even a strong child cannot take it all. this produces a distention of the breasts, causing what is known as "caked breasts," or "milk cake." this should be promptly attended to, as there is great danger of an abscess forming. =to prevent caked breasts.=--the way to relieve this condition is to gently but firmly rub the breasts with warm sweet-oil, continuing this for fifteen or twenty minutes at a time. an occasional use of the breast-pump is necessary also. =how to diminish supply.=--when weaning-time comes, the question arises how the secretion of milk may be diminished. this is best done by having the mother take as little liquid as possible, whether of water, tea, milk, soup, or anything of this kind. she should also take a gentle laxative each day, as a little hunyadi water, or laxative mineral water of any kind. then support the breasts by passing a broad band beneath them, and carrying it over the shoulders, compressing the breasts slightly, but not too greatly. the breast-pump should be used as soon as any distention becomes painful, and the breasts should be diligently rubbed with warm sweet-oil. =if you do not understand your ailments write to mrs. pinkham, lynn, mass. her advice is free and always helpful. such letters are strictly confidential and answered with the help of women only.= chapter xii. to prevent convulsions at childbirth. =work of the kidneys most important.=--the kidneys are constantly engaged in removing from the body certain poisonous substances which are held in solution in the urine. if they should fail to do this work, or if no urine should be secreted for even a few hours, most serious consequences would follow. =cause of convulsions.=--when these poisons are retained in the system to a sufficient degree they cause convulsions and unconsciousness, and are frequently fatal. the convulsions which some women have at childbirth are caused by this imperfect action of the kidneys. =to tell if danger is present.=--an examination of the urine at any time will tell whether the kidneys are acting well or not, and thus it is possible to determine whether there is danger of having these convulsions during confinement. therefore i urge upon all pregnant women the necessity of having their urine examined once or twice during the course of pregnancy, and certainly during the eighth or ninth month. =albumen in the urine.=--imperfect action of the kidneys is shown by the appearance of albumen in the urine. any competent physician can easily determine whether this albumen is in the urine or not, and if present he can take such prompt measures as to remedy the evil before any serious danger occurs. of course i know that hundreds of thousands of women pass safely through childbirth and have no unfavorable symptom at all; yet i also know that now and then a most valuable life is lost when it might just as well have been spared as not, if these simple suggestions had been carried out. it is the teaching of all the best medical authorities in the world that this precaution should be taken by every expectant mother. =symptoms of kidney trouble.=--when the kidneys are not performing their work properly, the mother may know it, herself. if she finds her feet and ankles swelling at night, if she has a puffy look under the eyes, and especially if the amount of urine passed in twenty-four hours is not so great as formerly, then there is probably albumen in the urine. in this case she should stop eating meat of all kinds, and live largely upon milk, keeping the bowels in laxative condition by using lydia e. pinkham's liver pills, and bathing the skin well once or twice a day. she should also begin at once the use of lydia e. pinkham's vegetable compound, resting assured that this will remove the congestion in the kidneys, and will cause a more free secretion of the urine. =self-abuse (masturbation).=--this is a cause of many of the diseases of women, also men. small girls learn the practice from larger ones, and through ignorance continue it often to maturity without knowing that it is bringing upon them a physical and moral injury. _if mothers instructed their daughters on this subject there would be fewer broken lives._ symptoms.--the main symptoms are wakefulness, restless nights, headache, indolence, melancholy, indisposition to study, forgetfulness, despondency, weakness in the back and private organs, no confidence in one's own abilities, a desire for seclusion from society; whites, hysterics, and inability to look any one in the face. sometimes the muscles are relaxed, limbs tremble, the skin is sallow and dry, with pain in the womb. =remarks. write to mrs. pinkham in perfect confidence, and she will tell you exactly what to do. delay is dangerous in this matter.= chapter xiii. dyspepsia, constipation, general debility, sleeplessness. =dyspepsia, acute.=--acute dyspepsia is usually caused by some improper diet, as the eating of an unusual article of food or of a larger amount than necessary. such articles of diet as cucumbers, unripe or overripe fruit, an excessive amount of sweets, rich salads, heavy puddings, etc., may so irritate the stomach that an acute attack of dyspepsia follows. =nature often cures.=--nature often makes a prompt cure in these cases by causing a sharp attack of vomiting or diarrhoea. if a cure is not made in this way, then we can imitate nature by giving an emetic, or by taking a laxative, in order to rid the body of the indigestible material as soon as possible. =treatment.=--if there is much pain in the stomach, a mustard plaster should be placed directly over the pit of the stomach, or cloths wrung out in hot water. for the next day following the attack the diet should be restricted to milk, or poached eggs on toast, or something of this kind. =chronic dyspepsia.=--it is chronic dyspepsia, however, which is so annoying because of its persistence. it has been called "the american disease" because so many people are troubled with it. =symptoms.=--persons suffering from chronic dyspepsia complain of a bad taste in the mouth, dry throat, nausea, and a feeling of great weight in the stomach for an hour or two after each meal. frequently there is no appetite whatever, or it may be even more ravenous than natural because of the irritation and inflammation in the stomach. when the latter is the case, food does not satisfy, and it becomes necessary to eat every two or three hours in order to quiet the gnawing and empty feeling in the stomach. the chronic dyspeptic suffers greatly from nervousness and depression of spirits; indeed, it seems almost impossible to maintain the usual cheerfulness. =thought to be the heart.=--many persons go to their family physician thinking they have a serious form of heart disease, when the whole trouble is with the stomach, the violent beating of the heart being simply a nervous manifestation caused by the irritable condition of the stomach. =two diseases closely associated.=--chronic dyspepsia is almost invariably associated with the diseases of women. indeed, the two seem almost inseparable, for whenever you find a woman complaining of soreness across the lower part of the bowels, irregular menstruation, ovarian irritation, inflammation of the bladder, leucorrhoea, etc., you will find a confirmed dyspeptic. the blood is thin and watery, the bowels are constipated, and the whole nervous system seems to be upset. =which disease is the cause?=--the question comes whether the disease in the pelvis causes the difficulty with the stomach, or whether the stomach produces the inflammation in the uterus and surrounding parts. probably one is true at one time and another at another time. the fact is that both conditions need correcting, and there is one remedy which answers perfectly in each case. =both must be cured.=--the digestion certainly cannot be perfect while there is this inflammation in the pelvic organs; while the latter can hardly maintain a healthy condition if the stomach fails to do its work. =both may be cured.=--by paying attention to a few rules of diet, and by taking lydia e. pinkham's vegetable compound for a short time, i believe every case will promptly yield to treatment. =cures dyspepsia of men.=--indeed, strange as it may seem, a great many men who have taken lydia e. pinkham's compound because they have seen its good action on the stomach in cases of other members of the family have written reporting good results. it certainly has a most soothing and strengthening power on this organ, while its gently stimulating effect on the whole alimentary canal brings about the most desirable changes. =regular action of the bowels.=--i would recommend that lydia e. pinkham's liver pills be taken each night in just sufficient doses to cause a regular action of the bowels each day. then if lydia e. pinkham's vegetable compound be taken, it will not only allay all inflammation in the stomach and impart great strength, but it will at the same time remove the soreness and pain in the pelvic organs. =a simple but valuable aid.=--all such persons will obtain relief by drinking a cupful of hot water at least half an hour before breakfast each morning; and if the case is very bad, then the hot water may be repeated before each meal. the water should be as hot as can be comfortably taken. =useful hints.=--i would strongly urge the necessity of thoroughly chewing the food and eating slowly. if this rule alone were observed there would be far less dyspeptics in the country. drink should be used sparingly at meal-time, also, for while the body requires a great deal of liquid during the day, yet this should be taken between meals rather than during meals. the stomach should certainly have time to rest from its work of digesting the food, hence nothing should be eaten between meals. the habit so many girls have of eating before retiring is very injurious to the health, and should be corrected at once. meals should be taken at regular intervals and not at any time when most convenient. =diet for dyspeptics.=--the chronic dyspeptic should use soups sparingly, for, as a rule, they are quite difficult of digestion, while they do not contain much nourishment. plain mutton and beef soup without much fat are the least harmful. such fish as pickerel, trout, shad, and white fish may be used moderately; while oysters, especially when raw, are easily digested. the best kinds of meat are roasted or broiled beef, lamb chops, and some fowl, as chicken. eggs are easily digested, and are exceedingly valuable as an article of diet for the dyspeptic. they may be cooked in almost any form except hard-boiled. they are highly nourishing, can be prepared in many delicate ways, and are, as i have said, as valuable an article of diet as the dyspeptic can have. persons with chronic dyspepsia do not digest vegetables well, as a rule, although such green vegetables as lettuce, green peas, asparagus, celery, and spinach may be used. potatoes often ferment in the stomach, producing gases, and should be used sparingly. toast is always well borne, but should never be buttered while hot. bread should not be used until it is at least a day old. rolled oats, cracked wheat, etc., may be taken, although with many they cause fermentation. nearly all cooked fruits are well borne by the stomach, and so are nearly all ripe fruits. puddings made from rice and custard are easily digested. milk is valuable at all times, and if the chronic dyspeptic bears it well, this diet alone will frequently make a marked cure. if it rests heavy on the stomach, a little lime water may be added to it in the proportion of a tablespoonful of lime water to a cupful of milk. =forbidden diet.=--there are certain articles of diet which the dyspeptic should not use under any circumstances. among such are fried foods of all kinds, pork, liver, veal, rich soups, turkey, goose, duck, mackerel, lobster, cucumbers, cabbage, turnips, parsnips, string beans, pies and cakes, cheese and nuts. =constipation.=--as we have already stated, constipation is productive of the most serious evils. when the lower bowel is distended, pressure is made upon the surrounding blood-vessels, and thus the circulation seriously interfered with. =causes inflammation of uterus.=--as a result, there is congestion in the blood-vessels of the ovaries and uterus, and inflammation of these organs is likely to follow with its long train of ailments. constipation also seriously interferes with the general health, producing nausea, indigestion, headache, backache, nervousness, general debility, etc. =daily movements necessary.=--nature intended that the alimentary canal should be relieved of its contents at least once every twenty-four hours, and if this is not done, then certain poisons are absorbed into the blood which produce the most undesirable effects. =to cure constipation.=--for constipation i strongly recommend lydia e. pinkham's liver pills. i know they give the most prompt and satisfactory relief. i have received letters from hundreds of women who have been cured of the most distressing ailments of the uterus and bladder simply by using these liver pills, and all because constipation was cured and in this way the cause of the suffering removed. =diarrhoea.=--diarrhoea, as a rule, is an effort of nature to get rid of some offensive material. while this may be the first reason for its existence, yet if it is allowed to go on, it produces such an irritation in the bowels that serious results may easily follow. =treatment.=--if the person is conscious of having eaten something indigestible, as unripe or overripe fruit, then it is best to aid nature by taking some gentle laxative, as a laxative dose of lydia e. pinkham's liver pills, thus hastening the removal of the indigestible substance. if, however, there have been a number of movements of the bowels, until the offending material is probably all removed, then the following plan is all that will be necessary to make a cure: let the person rest at full length upon a couch or bed, remaining as quiet as possible. for the diet nothing should be taken but hot milk. a glass of hot milk can be slowly sipped once every three hours, and nothing else whatever should be taken into the stomach for a day, at least, or until the diarrhoea is checked. if the pain is quite severe in the stomach or bowels, then a mustard plaster may be placed over the most painful part, or cloths wrung from hot water; or a poultice of linseed meal or slippery elm may be applied. i have seen the good results of this treatment of "rest and hot milk" in so many cases, and it is so exceedingly simple, that i earnestly recommend its trial. =general debility, exhaustion, anã¦mia.=--many women go about suffering from great debility, being hardly able to drag themselves through the day. when night comes they are too tired to sleep, and when morning comes it seems they are more tired than they were at night. all parts of the body partake of this general weakness. there are great discomfort and suffering through the lower part of the body, difficulty in passing the urine, constipation of the bowels, leucorrhoea, and all other affections which naturally come from an impoverished condition of the blood. =may be promptly cured.=--to all women who are suffering from this general debility, exhaustion, and nervous prostration i earnestly recommend lydia e. pinkham's blood purifier. if the inflammation in the uterus and surrounding organs is quite marked at the same time, then the blood purifier may be taken before meals and the vegetable compound after. if the female generative organs are not much involved, then the blood purifier may be used alone. =a grand medicine.=--this grand medicine has done great good, and i am confident it will build up the system, purify the blood, and greatly improve the general health. persons suffering from general debility of this kind do not prosper well on a milk diet alone. they need more hearty food, such as rare beefsteak, rare roast beef, lamb chops, and eggs. =sleeplessness.=--sleeplessness is frequently the result of a too liberal use of tea or coffee. many persons cannot take a cup of coffee at any time during the evening without lying awake many hours to pay for it. it is a strong stimulant to those who have a sensitive nervous system, and should be used only sparingly at all times and never after the midday meal. strong tea acts in this way upon a great many, and if any of my readers are troubled with sleeplessness, and yet at the same time use tea and coffee freely, i would suggest that they try, first of all, to do without these drinks and note the effect. =treatment.=--a warm (not hot) foot-bath taken just before retiring will often cause a good night's rest, as it draws the blood from the head, makes the circulation more evenly distributed, and in this way induces sleep. frequently a baby or young child may be made to sleep all through the night if a warm bath be given just before retiring. when the sleeplessness is due to nerve exhaustion, as is frequently the case, the very best results will follow the use of lydia e. pinkham's vegetable compound, because of its great nerve tonic properties. =a hard cold.=--whenever any one has taken a hard cold, it can often be speedily and completely broken up in the following manner: take a hot foot-bath for at least half an hour. while the feet are still in the hot water throw a blanket completely about the limbs and body, in order to retain all the heat possible. at the same time drink one or two cupfuls of hot lemonade, or hot ginger tea. then retire to bed, having the bed previously well warmed, if during the wintertime. put on plenty of covering, keeping a hot flat-iron or a hot water-bottle at the feet, and in every way try to induce free perspiration. after an hour or two, gradually remove the extra clothing. be careful about going out the next morning, for the body will be especially susceptible to the cold. in this way it is possible to break up a hard cold at once. if there is any tendency to cough, or any tightness or soreness in the chest, place a mustard plaster directly over the chest, and allow it to remain on until the skin is quite red. =sore throat.=--an old-fashioned remedy for sore throat, and a very good one, too, is to bind on each side of the throat a piece of salt pork. the surface of the pork may be slightly covered with black pepper, in order to increase its drawing power. this is allowed to remain on all night, but should be taken off in the morning. during the day a flannel is worn about the neck. a gargle for sore throat may be made by dissolving half a teaspoonful of chlorate of potash in a cupful of warm water. gargle the throat with this every hour or two during the day, but do not swallow the mixture. after this has been used for a day or two, then a solution may be made by adding a teaspoonful of pulverized alum to a cupful of warm water; this is applied to the inflamed sides of the throat by means of a swab. gargling the throat with a solution of ordinary extract of witch hazel, one part, and water two parts, also very useful. =croup.=--as a rule, croup may be quickly cured by the use of either hot or cold water. immediately the child begins to breathe hard and cough with a dry, hollow, barking cough, wring out a towel from cold water and apply around the throat, covering this with a dry towel. the wet towel should be changed in a few minutes, just as soon as it becomes a little warm. often before the second cloth is removed the spasm will be broken, and the danger passed. _cool_ water will not answer; it must be _cold_. if the spasm does not break, and the breathing does not become easy within fifteen or twenty minutes, then change to hot water. wring out the cloth from water as hot as can be borne and apply about the neck, changing in a few moments, and so on. =how to lose flesh.=--i have often been asked whether it were possible to have the flesh reduced without in any way affecting the general health. if the person be only slightly heavier than usual, and is in the best of health, it certainly seems wrong to experiment in any way to reduce the weight, especially when this is done only to better follow the dictates of fashion. if, however, the excess of flesh is becoming so great as to be uncomfortable, to interfere with the regular work, or to cause weak action of the heart, etc., then something should be done. there are a few rules which a person may follow to advantage in such cases, although the change should be made gradually. so long as a person continues to gain in flesh, it is positive evidence that more food is being taken than necessary. therefore the first rule is that the quantity of food should be gradually diminished. the second rule is that exercise should be taken regularly. this will keep up the general health, while it will cause the fat to be more evenly distributed over the body. another rule is to keep the bowels well open, so that there may be at least two movements daily. for this special purpose the mineral laxative waters are best. =diet for reducing the flesh.=--fatty foods should be avoided, and so should all drinks in excess. foods containing sugar or starch should be taken sparingly, as oatmeal, potatoes, rice, cakes, sweetened tea and coffee. milk is very fattening to many, hence should not be used. the eminent dr. mitchell, of philadelphia, instituted a course of treatment for reducing the weight, which is quite rigid, but nevertheless effective. the regular diet should be changed gradually until it meets dr. mitchell's demands. he prescribes outdoor exercise, and a diet of one cupful of milk and one egg every three hours when awake. no other food or drink is allowed for twenty days, when the list of foods is gradually extended. there are a number of anti-fat remedies upon the market, but many of them depend for a cure upon their power to disturb digestion, and thus interfere with the general health. =how to gain flesh.=--when it is natural for persons to be thin, it is quite impossible for them to gain in weight under any kind of diet or treatment. many persons, however, are thin simply because some of the digestive organs do not perform their work properly; or because the diet is not the right kind. thin persons need good meats and some vegetables. if the digestion is all right, then such meats as mutton, chicken, broiled bacon, broiled ham, etc., may be used; also rare broiled steak, rare roast beef, etc. eggs may be used in any way except hard-boiled. good bread, oatmeal, cracked wheat, hominy, etc., are good. such indigestible foods as pork and veal, thin soups, cabbage, turnips, pickles, pies, and pastries of all kinds should not be used. often a good preparation of cod-liver oil will increase the weight; and this is also true of many of the extracts of malt. it is useless, however, to try to increase the weight by using a generous diet, unless the digestion is in good order. when the digestion is weak, the person should take lydia e. pinkham's vegetable compound because of its power to strengthen the digestion and enable the system to obtain all the good possible from the food. =pimples, rashes, eruptions.=--many persons, especially young girls, are afflicted with pimples on the face, rashes, blackheads, etc. to cure this condition it is necessary that the bowels be made to act regularly each day, which is easily done by the use of lydia e. pinkham's liver pills. then a good course of treatment should be taken with lydia e. pinkham's blood purifier in order to make the blood perfectly pure in every way. attention should also be paid to the diet, and such indigestible articles as pork, pickles, rich pies and cakes, and rich sauces, sweetmeats and nuts should be avoided. for local treatment, the face should be washed each day in warm, soapy water, using the best castile soap. then with a sponge or wash cloth wash off this water with as hot water as can be borne. it is best to keep up this sponging with the hot water for at least five minutes in order that the face may become thoroughly steamed. the face should then be wiped dry and rubbed briskly for a few minutes. =burns.=--burns are likely to occur at any time in the household, and one should always know what to do promptly. the best treatment is to add a teaspoonful of ordinary baking-soda to a cupful of water. saturate some cloths in this solution and lay them over or loosely bind them about the burned part. this will take out the pain and sting at once. as the cloths become dry, more of the solution should be poured over them, and they should not be removed from the burned parts. after a few hours, these wet cloths may be replaced by cloths well covered with vaseline. =if you do not understand your ailments write to mrs pinkham. her advice is free and always helpful. such letters are strictly confidential; they are never shown without the writer's express permission; women only assist in answering them.= free medical advice to women all correspondence strictly confidential +lady with raised hand+ in addressing mrs. pinkham you are confiding your private ills to a woman--a woman who speaks from a greater experience in treating women's diseases than can any living physician--male or female. you can talk freely to a woman when it is revolting to relate your private troubles to a man--besides, a man does not understand--simply because he is a man. many women suffer in silence and drift along from bad to worse, knowing full well that they ought to have immediate assistance, but a natural modesty impels them to shrink from exposing themselves to the questions and probably examinations of even their family physician. it is unnecessary. without money or price you can consult a woman, who can speak from a greater actual experience than can any local physician in the world. every one will agree that there are the strongest of all reasons why, if we are ill, we should appeal to the person who knows the most about the kind of illness with which we are afflicted--one who has had the greatest experience in treating just such cases and meeting just the symptoms that are manifest in our particular case. what confidence does one gain by consulting one who has occasionally met a case just like ours, but has had no great experience? none whatever. all treatment under such a person must of necessity be experimental. but in writing mrs. pinkham you consult one who has, actually filed in her office for ready reference, an immense correspondence with patients suffering from female ills which has been constantly going on for more than twenty-five years; and it is safe to say there is not a case or complication of female derangements with which she is not familiar. it is a positive fact, easily verified, that within the last few months she, with her corps of trained women assistants, has advised in over one hundred thousand cases, and that a vast number of the women of this country owe the restoration of their health to her advice and lydia e. pinkham's vegetable compound. now, if a woman is ill and miserable, it seems to us only simple justice to herself that she should avail herself of the help of a woman of such enormous experience. mrs. pinkham's standing invitation. women suffering from any form of female weakness are invited to promptly communicate with mrs. pinkham, at lynn, mass. she asks nothing in return, except their good will, and her advice has relieved thousands. surely any woman, rich or poor, is very foolish if she does not take advantage of this generous offer of assistance. =address simply mrs. pinkham, lynn, mass., u. s. a.= el compuesto vegetal de lydia e. pinkham es un remedio seguro para todas las enfermedades de las mujeres, incluyendo la caã­da del ãºtero, leucorrea, menstruaciones irregulares y dolorosas, inflamaciones y ulceraciones de la matriz y del

terribles dolores en el abdomen, espalda etc., desmayos, pesadez en las extremidades, y de toda clase de otros dolores. una cura segura se encuentra en el compuesto vegetal de lydia e. pinkham. =leucorrea (ã³ flores blancos).=--uno de los primeros sã­ntomas de la inflamacã­on del ãºtero es la leucorrea, familiarmente conocida bajo el nombre de flores blancos, la cual consiste en una secreciã³n blancusca de la vagina la cual debilita muchã­simo el sistema y produce una irritaciã³n de la membrana mucosa que reviste el canal vaginal. el uso regular del compuesto vegetal, por sus efectos en la constituciã³n, y la lociã³n sanativa de lydia e. pinkham usada en inyecciones curarã¡ positivamente los casos mã¡s graves de leucorrea. la negligencia de esta dolorosa enfermedad originarã¡ ãºlceras, flujos excesivos, estableciendo los cimientos para la mã¡s terrible de todas las enfermedades--el cancer. =caã­da del utero.=--existen muchos desplazamientos del ãºtero, pero el mã¡s principal es ã©l conocido generalmente con el nombre de la caã­da del utero. esto es debido muchas veces ã¡ la flojedad de los ligamentos que soportan este ã³rgano. el compuesto vegetal de lydia

enfermedad va siempre acompaã±ada de algunos dolores de la regiã³n de los ovarios y de una sensaciã³n de pesadez especialmente durante la menstruaciã³n. a menudo el dolor extiã©ndese por el costado y

durante este perã­odo las mujeres sufren toda clase de dolores y enfermedades, pero si el compuesto vegetal de lydia e. pinkham se toma regularmente este cambio importante puede ser pasado sin peligro de enfermedades ã³ muerte. =las enfermedades de los riã±ones y de la vejiga= son comunes en ambos sexos, generalmente de difã­cil curaciã³n, pero pueden curarse si se atienden ã¡ tiempo; nada sin embargo es tan fatal como el no atenderlos debidamente ã¡ su tiempo, siendo la muerte el resultado inevitable. el compuesto vegetal de lydia e. pinkham no reconoce rival entre los remedios que para estas enfermedades han sido descubiertos. es digno de absoluta confianza tanto por hombre como por mujer. =los dolores de la espalda= no son una enfermedad pero son uno de los principales sã­ntomas;

espalda. el compuesto vegetal de lydia e. pinkham curando las enfermedades del ãºtero y de los riã±ones harã¡ desaparecer los dolores de la espalda. =dispepsia ã© indigestiã³n.=--nada en el mundo

alla qvinnosjukdomar, sã¥som lifmoderns nedfallande, hvitsot, oregelbunden och smã¤rtsam rening, inflammation och sã¥rnad p㥠lifmodern och ã¤ggstockarne, samt alla andra svagheter uti de qvinliga skaporganen, ã¤fvensom njurlidande hos bã¥da kã¶nen. det ã¤r sammansatt af utvalda och renaste slag af rã¶tter och ã¶rter, sã¥som naturen sjelf frã¥mstã¤llt dem fã¶r botandet af qvinnans lidanden. =rening.=--fã¶r tidig rening ã¤r icke ã¶nskvã¤rd, ehuru densamma vanligen bã¶rjar vid omkring tretton intill femton ã¥rs ã¥lder; emellertid beror dervid mycket p㥠flickans kroppsbyggnad. om hon nã¥tt denna ã¥lder och ã¤nnu icke haft rening, bã¶r modren fã¤sta sã¤rskild uppmã¤rksamhet dervid; hennes dotter blir antagligen mager och blek, med en egendomlig gulblek hy och hon blir ett sã¤kert och lã¤tt offer fã¶r lungsot och nervã¶s nedslagenhet. ingenting i verlden nã¤r upp till lydia e. pinkhams vegetable compound i dylika fall. det bidragar att ã¥stadkomma den vigtiga fã¶rã¤ndring uti en flickas lif, som bã¶r ega rum vid omkring denna ã¥lder och fã¶rebygger sã¥lunda ã¥ratal af elã¤nde, som ã¤r en sã¤ker fã¶ljd af uraktlã¥tenhet. medicinen mã¥ste tagas bestã¤mdt enligt fã¶reskrift, intill reningen intrã¤ffar regelbundet hvarje tjuguã¥ttonde dag. om inelfvorna ã¤ro benã¤gna att hoptrã¤nga sig, borde lefver-piller (lydia e. pinkhams liver-pills) begagnas, hvilka blifvit sã¤rskildt sammansatta fã¶r qvinnans bruk och verka i fullkomlig harmoni med vegetable compound. =fã¶rhindrande af flytningen= ã¤r ett uppharonde sedan reningen vederbã¶rligen bã¶rjat. om ett upphã¶rande eger rum, s㥠framt det icke ã¤r en fã¶ljd af hafvandeskap eller gifvande af di, ã¤r det ett allvarligt fall och lydia e. pinkhams vegetable compound bã¶r tagas tills reningen ã¥ter blir regelbunden. den

det inverkar ej om detta fã¶rhã¥llande nyligen intrã¤dt eller om det egt rum under mã¥nga mã¥nader; om lydia e. pinkhams vegetable compound tages regelbundet och enligt fã¶reskrift ã¤r ett botande sã¤kert. =fã¶r ymnig rening= fã¶rekommer ofta hos dem, som ã¤ro blodfulla, liksom hos dem som ã¤ro bleka och svaga. lydia e. pinkhams vegetable compound har ã¥tstadkommit ã¥tskilliga af de mest fã¶rvã¥nansvã¤rda botaden i just dylika fall. fã¶r fã¶r ymnig rening eller flytning rekommendera vi alltid lydia e. pinkhams vegetable compound i torr form, antingen som piller eller kakor. =inflammation och sã¥rnad p㥠lifmodern= ã¤r orsaken till nã¤stan alla qvinnosjukdomar. lydia e. pinkhams vegetable compound har botat mera ã¤n en million fall af lifmoderfel. de skildringer, som erhã¥llits frã¥n qvinnor, hvilka varit dã¶dsjuka och som botats genom lydia e. pinkhams vegetable compound ã¤ro nã¤stan otroliga. en qvinna vet sã¤kerligen om hon har nã¥got slags lifmoderfel, enã¤r dylikt nã¤stan alltid ã¥tfã¶ljes af en nedtyngande kã¤nsla uti underlifvet, ryggvã¤rk, svimmingsanfall, styfhet i lederna och all annan tã¤nkbar vã¤rk och smã¤rta. ett aldrig svikande botemedel ã¤r lydia e. pinkhams vegetable compound. =leucorrhea eller hvitflytning.=--en af de fã¶rsta symptomerna af lifmoderns inflammation ã¤r leucorrhea, vanligen kallad "hvitt," hvilken bestã¥r af en hvit flytning frã¥n moderslidan och som ã¤r mycket kraftnedsã¤ttande fã¶r systemet och retande fã¶r moderslidans kã¤nsliga slemhinna. ett regelbundet begagnande af lydia e. pinkhams vegetable compound p㥠grund af dess inverkanp㥠kroppsbeskaffenheten och lydia e. pinkhams lã¤kande medel fã¶r insprutning uti moderslidan, botar sã¤kert de allvarligaste fall af hvitflytning. fã¶rsummande af denna ledsamma sjukdom fã¶rorsakar sã¥rnader, ã¶fverdrifven flytning och lã¤gger grunde fã¶r den forskrã¤ckligaste af alla sjukdomar nemligen krã¤fta. =lifmoderns nedfallande.=--det finnes mã¥nga olika rubbningar hos lifmodern, den vanligaste kã¤nd under namn af lifmoderns nedfallande. detta beror hufvudsakligast p㥠fã¶rslappning af de band som uppbara detta organ eller hã¥lla det p㥠sin plats. lydia e. pinkhams vegetable compound starker dessa band, lindrar inflammation och ã¥terstã¤ller s㥠smã¥ningen delarne uti deras behã¶riga lã¤ge. lydia e. pinkhams vegetable compound borttager svullnad uti lifmodern i dess tidigare stadium lika sã¤kert som solen skiner. =inflammation uti ã�ggstockarne= ã¤r en sã¤rdeles allvarlig sjukdom, som angriper qvinnan mellan 20 och 40 ã¥rs ã¥lder. den ã¥tfã¶ljes alltid af ã¶mhet och hã¥rda smã¤rtor i trakten af ã¤ggstockarne och en kã¤nsla af uppfyllnad isynnerhet under reningen. ofta utstracka sig smartorna till sidan och ryggen, isynnerhet till venstra sidan, med ett stã¤ndigt begã¥r att urinera. s㤠framt icke denna sjukdom genast hã¤fvas, kan ingenting rã¤dda patienter frã¥n operationsknifven. lydia e. pinkhams vegetable compound har emellertid botat tusentals qvinnor fã¶r sjukdomar uti ã¤ggstockarne och rã¤ddat mã¥ngfaldiga frã¥n hospitalet och en allvarlig operation. =ofruktbarhet= har often sin orsak uti ytterlig svaghet och kroniskt inflammeradt tillstã¥nd af lifmodern. regelbundet begagnande af lydia e. pinkhams medicin har ofta ã¥terstã¤llt lifmoderns fruktbara organer till deras normala tillstã¥nd och lindrat frã¥n den bekymrande tanken att ofruktbarheten var obotlig. =fã¶rã¤ndring i lifvet= ar en farlig period fã¶r alla qvinnor, som hunnit till 45 ã¥rs ã¥lder. under denna tid har qvinnan all slags sjukdom och smã¤rta, men om lydia e. pinkhams vegetable compound tages regelbundet, kan denna vigtiga fã¶rã¤ndring i en qvinnas lif passeras utan fara fã¶r sjugdom eller dã¶d. =njurlidande och blã¥skatarr= hos bã¥da kã¶nen aro vanliga och svã¥ra sjukdomar, men de kunna botas om de tagas itu med i rã¤tt tid. ingenting ar emellertid s㥠olycksbringande som symptomerna till dessa sjukdomar om de ej gifvas akt p㥠i tid och dã¶den ã¤r oundviklig. lydia e. pinkhams vegetable compound ã¶fvertrã¤ffas ej af nã¥got annat botemedel, som nã¥gonsin uppstã¥ckts fã¶r botande af alla sjugdomar i njurarne och blã¥san. det ã¤r fullt tillfã¶rlitligt bã¥de fã¶r mã¤n och qvinnor. =ryggvark= ã¤r icke en sjukdom utan en tydlig symptom da sjukdom fã¶refinnes uti skaporganen och ger sig tillkã¤nna som om det vore uti den stora sympatiska nerv, som har ett af sina fã¶rnã¤msta lã¤gen i lã¤gre delen af ryggen. lydia e. pinkhams vegetable compound, som hã¤fver lifmoders-, ã¤ggstocks-, och njurlidanden, botar tryckande ryggvã¤rk. =magsyra och dã¥lig matsmã¥ltning.=--ingenting verlden har nã¥gonsin uppstã¤ckts, som uppnã¥r lydia e. pinkhams vegetable compound for magsjukdomar. =hafvande tillstand.=--vid barnsbã¶rd intraffer mycken smã¤rta och lidande, som kunde helt och hã¥llet undvikas om den blifvande modern stã¤rkte sitt system genom regelbunden behandling med lydia e. pinkhams vegetable compound under en

hudsjukdomar m. m. sã¤ljes hos apotekare, prepareradt af lydia e. pinkham medicine company, lynn, mass., fã¶renta staterna. le remã�de vã�gã�tal de lydia e. pinkham. =le remã¨de vã©gã©tal de lydia e. pinkham= est un remã¨de absolument sã»r pour toutes les maladies de femme telles que le prolapsus de la matrice, la leucorrhã©e, les menstrues irreguliã¨res et douloureuses, l'inflammation et l'ulcã©ration de la matrice et des ovaires, ainsi que pour toutes les autres affections des organes gã©nitaux de la femme, et les maladies des reins et du foie des deux sexes. il se compose des herbes et racines les plus pures, telles que les pourvoit la nature elle mãªme. =menstrues.=--il n'est pas ã  dã©sirer que les rã¨gles aient lieu a un ã¢ge trop jeune, quoiqu'en gã©nã©ral les menstrues commencent entre la 13e et la 15e annã©e, la constitution de la jeune fille y jouant un certain rã´le. si la fille a atteint cet ã¢ge et qu'elle n'ait pas encore ses rã¨gles, la mã¨re ne saurait ãªtre trop soigneuse; il est probable que la fille est pã¢le et maigre, et que son teint montre cette couleur livide qui nous fait craindre qu'elle ne devienne sous peu la victime de la phthisie et qu'elle ne devienne fortement neurasthã©nique. pour empãªcher un tel malheur rien n'ã©gale "lydia e. pinkham's vegetable compound." il produit d'une maniã¨re salutaire et prompte le changement qui devrait alors avoir lieu, en prã©venant ainsi de longues annã©es de souffrances, rã©sultat inã©vitable de tout manque de prã©caution. lydia e. pinkham's vegetable compound doit ãªtre pris strictement selon les instructions, jusqu'ã  ce que les rã¨gles aient lieu tous les 28 jours. si, de plus, il y a de la constipation, on se servira des pilules de foie de lydia e. pinkham, faites exprã¨s pour l'usage des femmes et opã©rant entiã¨rement d'accord avec le remã¨de. =l'absence des rã¨gles= aprã¨s qu'elles ont commencã© une fois, ã  moins qu'elle ne soit due ã  la grossesse ou ã  l'allaitement, est une affaire de la plus grande importance et personne ne devrait manquer de se servir de lydia e. pinkham's vegetable compound jusqu'ã  ce que de nouveau les menstrues se montrent reguliã¨rement. =rã¨gles douloureuses.=--il y a bien des femmes qui, pendant le temps de leurs rã¨gles, souffrent des douleurs tout ã  fait terribles. notre remã¨de guã©rira d'une maniere sã»re cette affection n'importe si c'est un cas rã©cent ou vieux de plusieurs mois. on peut s'attendre ã  une guã©rison sã»re et efficace pourvu que le remã¨de soit pris reguliã¨rement et suivant les instructions. =les rã¨gles excessives= se montrent d'abord chez des personnes sanguines et chez les personnes affaiblies et pales. notre remã¨de, lydia e. pinkham's vegetable compound, a obtenu des rã©sultats tout ã  fait merveilleux dans ces cas. pour guã©rir l'excã¨s ou l'hã©morrhagie des rã¨gles nous conseillons l'emploi du remã¨de dans sa forme sã¨che, c'est ã  dire en pilules ou en pastilles. =l'inflammation ainsi que l'ulcã©ration de la matrice= peuvent ãªtre regardã©es comme cause de presque toutes les maladies de la femme. cependant lydia e. pinkham's vegetable compound a guã©ri plus d'un million de maladies de la matrice. les rapports que nous recevons des femmes qui ont failli en mourir et qui ensuite ont ã©tã© gueries, sont presque incroyables. la femme peut s'assurer assez facilement, si elle est atteinte ou non d'une affection de la matrice, vu le fait qu'ordinairement elle est sujette ã  des tiraillements d'estomac, ã  des peines dans les reins, ã  des ã©vanouissements, ã  l'engourdissement des membres et ã  une foule d'autres douleurs. le seul remã¨de infaillible pour guã©rir toutes ces affections est lydia e. pinkham's vegetable compound. =la leucorrhã©e= que nous connaissons plus familiã¨rement sous le nom de "fleurs blanches," reprã©sente un des premiers symptã´mes de l'inflammation de la matrice. le mal se montre sous la forme d'une secrã©tion blanchã¢tre du vagin, enfaiblissant le systã¨me et exerã§ant un irritation trã¨s sã©rieuse sur la muqueuse du vagin. l'emploi rã©gulier de lydia e. pinkham's vegetable compound, grã¢ce ã  son effet sur le systã¨me, ainsi que de la lotion sanitaire de lydia e. pinkham (lydia e. pinkham's sanative wash) appliquã©e sous forme d'injections dans le vagin, ne tardera guã¨re de guã©rir les cas les plus obstinã©s de leucorrhã©e. en nã©gligeant cette maladie dã©sastreuse on est sã»r de donner lieu ã  des secrã©tions excessives, ã  des ulcã¨res ainsi qu'a la plus dangereuse de toutes les maladies--le cancer. =prolapsus de la matrice.=--il y a un grand nombre de dã©placements dont le plus important est appelã© "le prolapsus de la matrice." celui-ci est produit d'abord par une relaxation des ligaments qui, dans leur ã©tat normal, maintiennent cet organe ã  sa place. lydia e. pinkham's vegetable compound fortifiera ces ligaments, l'inflammation disparaã®tra et peu ã  peu l'organe sera remis dans sa condition normale. notre remã¨de aura de plus un succã¨s indiscutable pour guã©rir toutes les tumeurs de la matrice pourvu qu'on commence ã  s'en servir dã¨s leurs premiã¨re phases. =l'inflammation des ovaires= est une des maladies les plus dã©sastreuses atteignant les femmes entre la vingtiã¨me et la quarantiã¨me annã©e. les personnes qui en souffrent s'aperã§evront vite d'une sensibilitã©

namen "vegetable compound" auf den markt gebracht, ist ein absolut zuverlã¤ssiges heilmittel fã¼r sã¤mmtliche frauenkrankheiten, einschlieã�lich vorfall der gebã¤rmutter, leukorrhoe, unregelmã¤ã�ige und schmerzhafte menstruation, entzã¼ndung und geschwã¼rbildung in der gebã¤rmutter und den eierstã¶cken, ferner fã¼r alle sonstigen schwã¤chezustã¤nde in den weiblichen geschlechtsorganen und fã¼r nierenkrankheiten bei beiden geschlechtern. das mittel ist aus den reinsten und erlesensten wurzeln und krã¤utern, wie sie mutter natur zur heilung aller frauenleiden selbst geschaffen hat, zusammengestellt. =menstruation.= eine ã¼bermã¤ã�ig frã¼he menstruation ist keineswegs wã¼nschenswerth; obwohl die monatsregel oder menstruation im allgemeinen in der zeit vom dreizehnten bis zum fã¼nfzehnten jahre aufzutreten pflegt, wobei jedoch viel von der constitution des betreffenden mã¤dchens abhã¤ngt. hat sie jedoch dieses alter erreicht, und sollte sich die menstruation noch nicht eingestellt haben, so muã� die mutter sich um die sache bekã¼mmern. wahrscheinlich ist das junge mã¤dchen mager und blaã�, wobei der teint ein besonders, gelbliches aussehen hat, so daã� es nur zu leicht ein opfer der auszehrung und allgemeiner nervenschwã¤che wird. fã¼r solche fã¤lle ist lydia e. pinkham's vegetable compound geradezu unvergleichlich. es trã¤gt vor allem dazu bei, daã� der wechsel im mã¤dchenleben, der um diese zeit eintreten sollte, auch richtig stattfindet, und es verhindert somit jahrelanges leiden, das in der regel eine sichere folge einer vernachlã¤ssigung in diesem sinne bildet. lydia e. pinkham's vegetable compound sollte genau nach vorschrift eingenommen werden, bis die regeln regelmã¤ã�ig sich alle 28 tage einstellen. zeigt sich anlage zu verstopfung, so muã� man auch lydia e. pinkham's leberpillen brauchen, die speciell fã¼r den gebrauch von frauen zusammengestellt worden sind und in jeder beziehung harmonisch mit dem "compound" zusammenwirken. =ausbleiben der regeln.= mit diesem ausdruck bezeichnet man das nichterscheinen der menstruation, nachdem dieselbe einmal zu erscheinen angefangen hat. ein derartiges ausbleiben, sofern es nicht der schwangerschaft oder dem stillen zuzuschreiben ist, ist eine ernsthafte angelegenheit, und lydia e. pinkham's vegetable compound muã� eingenommen werden, bis die menstruation wieder regelmã¤ã�ig eintritt. durch den gebrauch dieses mittels kann man zuverlã¤ssig alle unregelmã¤ã�igkeiten beseitigen. =schmerzhafter monatsfluã�.= bei vielen frauen verursacht der monatsfluã� ã¼beraus groã�e schmerzen, und alle, die daran leiden, sollten ja nicht verfehlen, sich durch den gebrauch von lydia e. pinkham's vegetable compound von dieser wahrhaften geiã�el zu retten. dabei ist es gleichgã¼ltig, ob der fall ein akuter ist oder ob er schon viele monate gedauert hat. vorausgesetzt, daã� das vegetable compound regelmã¤ã�ig und genau nach vorschrift genommen wird, darf man zuverlã¤ssig eine heilung erwarten. =zu starker monatsfluã�.= sowohl vollblã¼tige als auch besonders bleichsã¼chtige und schwã¤chliche personen leiden hã¤ufig unter zu starker menstruation. gerade mit bezug auf derartige zustã¤nde vermag lydia e. pinkham's vegetable compound auã�erordentlich gã¼nstige resultate aufzuweisen. doch empfehlen wir bei zu reichlich auftretender blutung lydia e. pinkham's vegetable compound in seiner trockenen form, d. h. in der form von pillen oder pastillen einzunehmen. beinahe alle frauenkrankheiten haben ihren ursprung in =entzã¼ndung und geschwã¼rbildung in der gebã¤rmutter=, und es ist daher nicht genug hervorzuheben, daã� lydia e. pinkham's vegetable compound schon mehr als eine million fã¤lle von gebã¤rmutteraffektionen glã¼cklich geheilt hat. fast unglaublich klingen die berichte vieler frauen, die todtkrank waren, und die dem vegetable compound ihre rettung verdanken. es ist nicht schwer fã¼r eine frau zu erkennen, ob sie an einer affektion der gebã¤rmutter leidet, da eine derartige erkrankung fast stets von ziehenden, ã¤uã�erst empfindlichen schmerzen im unterleib, rã¼ckenschmerzen, ohnmachtsanfã¤llen, erstarrung â»einschlafenâ« der gliedmaã�en, sowie von einer reihe anderer schmerzen begleitet ist. lydia e. pinkham's vegetable compound ist ein unfehlbares mittel gegen alle derartigen erkrankungen. =die leukorrhoe oder der weiã�e fluã�.= eines der allerersten symptome, die eine entzã¼ndung der gebã¤rmutter anzeigen, ist die leukorrhoe, oder wie man sich gewã¶hnlich ausdrã¼ckt: der weiã�e fluã�. derselbe zeigt sich als eine weiã�liche absonderung aus der vagina oder mutterscheide, die den kã¶rper auffallend angreift und schwã¤cht und besonders die empfindliche schleimhaut des scheidekanals irritiert. aber selbst die hartnã¤ckigsten fã¤lle von weiã�em fluã� lassen sich positiv kurieren durch den gebrauch von lydia e. pinkham's vegetable compound in verbindung mit lydia e. pinkham's "sanative wash" oder â»hygienischem waschwasser.â« das erstere stã¤rkt das system und das zweite heilt die lokalen erscheinungen, da es direct in die scheide eingespritzt wird. man hã¼te sich ja, diese art von krankheit zu vernachlã¤ssigen, da sich sonst leicht geschwã¼re und ã¼bermã¤ã�ige absonderung einstellen kã¶nnen, die oftmals den ersten grund zu der schrecklichsten aller krankheiten -dem krebs legen. =gebã¤rmuttervorfall.= es giebt eine reihe von fã¤llen, wo die gebã¤rmutter eine verã¤nderung ihrer normalen lage erleidet; von diesen ist der wichtigste der sogenannte gebã¤rmuttervorfall. derselbe kommt hauptsã¤chlich von einer erschlaffung der bã¤nder her, die dieses organ stã¼tzen und in seiner richtigen lage erhalten sollen. lydia e. pinkham's vegetable compound stã¤rkt diese bã¤nder, vermindert die entzã¼ndung und verleiht nach und nach den erkrankten theilen ihren frã¼heren, normalen zustand wieder. die =entzã¼ndung der eierstã¶cke= ist eine ã¤uã�erst schwere erkrankung, die frauen im alter von 20 bis 40 jahren befã¤llt. sie ist stets von groã�er empfindlichkeit und scharfen schmerzen in der gegend der eierstã¶cke begleitet, wozu sich ein gefã¼hl der vã¶lle, besonders zur zeit der menstruation, gesellt. die schmerzen erstrecken sich auch hã¤ufig auf die seite und den rã¼cken, mit vorliebe aber auf die linke seite, in verbindung mit fortwã¤hrendem verlangen das wasser abzuschlagen. wird nicht prompt gegen diese erkrankung eingeschritten, so vermag nichts den kranken vom messer des chirurgen zu retten. lydia e. pinkham's vegetable compound hat aber tausende von fã¤llen von eierstockerkrankungen geheilt und hat viele frauen der nothwendigkeit enthoben, sich im hospital einer gefã¤hrlichen operation auszusetzen. =unfruchtbarkeit= ist oft weiter nichts als der folgezustand ausnehmender schwã¤che, sowie einer chronischen entzã¼ndung der gebã¤rmutter. der regelmã¤ã�ige gebrauch von lydia e. pinkham's vegetable compound hat schon in vielen fã¤llen die weiblichen zeugungsorgane wiederum ihrer normalen thã¤tigkeit zurã¼ckgegeben und eine anscheinend gã¤nzliche unfruchtbarkeit glã¼cklich gehoben. die sogenannten =wechseljahre= oder die =menopause= sind eine zeit wirklicher gefahr fã¼r alle diejenigen frauen, die das 45. jahr ã¼berschritten haben. wã¤hrend dieser zeit sind die frauen allen mã¶glichen beschwerden und erkrankungen ausgesetzt, die sich aber alle vermeiden lassen, ohne ernstliche krankheit oder sogar den tod fã¼rchten zu mã¼ssen, wenn man wã¤hrend dieser sehr wichtigen periode des frauenlebens regelmã¤ã�ig lydia e. pinkham's vegetable compound einnimmt. =nierenund blasenbeschwerden= sind hã¤ufige und hartnã¤ckige leiden beider geschlechter. sie sind alle heilbar, vorausgesetzt, daã� man sich bei zeiten um sie kã¼mmert; werden sie aber vernachlã¤ssigt, so kã¶nnen sie leicht verhã¤ngnisvoll werden und sogar den tod nach sich ziehen. sicher ist aber, daã� lydia e. pinkham's vegetable compound als ausgezeichnetes mittel zur heilung aller nierenund blasenkrankheiten von keinem anderen bisher erfundenen mittel ã¼bertroffen wird. mã¤nner und frauen kã¶nnen volles vertrauen in dasselbe setzen. =rã¼ckenschmerzen= sind nicht eine krankheit, sondern sind vielmehr nur ein, gewisse krankheiten anzeigendes, symptom. bei krankheiten der geschlechtsorgane wird der groã�e sympathische nerv, dessen hauptcentrum im unteren theil des rã¼ckens liegt, in mitleidenschaft gezogen und verkã¼ndet sozusagen das vorhandensein einer derartigen krankheit. dadurch, daã� lydia e. pinkham's vegetable compound alle affektionen der gebã¤rmutter, der eierstã¶cke und der nieren heilt, heilt es auch das so sehr peinigende rã¼ckenweh. =verdauungsbeschwerden.= es giebt in der ganzen welt kein besseres mittel gegen alle stã¶rungen der magenthã¤tigkeit als gerade lydia e. pinkham's vegetable compound. =schwangerschaft.= oftmals ist die geburt eines kindes mit vielen schmerzen und beschwerden fã¼r die mutter verbunden, und doch kã¶nnten alle diese zum groã�en theil vermieden werden, wollte nur die mutter ungefã¤hr zwei monate vor der entbindung anfangen, ihren kã¶rper durch den regelmã¤ã�igen gebrauch von lydia e. pinkham's vegetable compound zu krã¤ftigen. gebrauchsanweisung. fã¼r sã¤mmtliche oben erwã¤hnte beschwerden nehme man alle vier stunden wã¤hrend des tages je einen eã�lã¶ffel voll von lydia e. pinkham's vegetable compound ein. * * * * * man weiche ein viertel packet von lydia e. pinkham's sanative wash in genã¼gend wasser, um nach dem durchseihen ein pint zu haben. ist die absonderung sehr bedeutend,

following testimonials. dear mrs. pinkham: i wish all women suffering from female troubles might know what you have done for me. a year ago last june i was very sick, and on examination my physician said i had polypus of the womb and that i would not stop flowing until i had an operation. i always had a horror of operations and could not bear the thoughts of having one, as i am a nervous person. i wrote to you and followed all your directions faithfully, and all the while i prayed that i might not have to have one. at that time i could hardly walk across the floor and i was pale and thin. now i weigh one hundred and thirty-five pounds, do all my work, and my husband and children say that i am growing young. i am still taking your medicine and will do so until after the turn of life. mrs. nelson bavier, west hartford, conn. dear mrs. pinkham: i suffered for over three years with female weakness brought on by falling on an icy pavement. i had frequent backache and fearful headaches, blinding me with pain. i also had intense pains at the menstrual period. my family physician prescribed several remedies, but although he was considered an excellent physician, he was unable to relieve me. a cousin who visited me had a bottle of lydia e. pinkham's vegetable compound with her and spoke so highly of its efficacy that i took a few doses of it. i was pleased and surprised to find that it seemed to relieve my pains in twenty-four hours. i took it regularly, and within twenty-four hours more i felt like a different woman, and two weeks continued use of it restored me to health and strength such as i had not known in years. i consider lydia e. pinkham's vegetable compound the only medicine on the market which is reliable for the ills of the sex. miss maud bell, 408 lanwee west, lansing, mich. grand recorder, daughters of american independence. september 22, 1902. i would like to have your advice as i am a married woman and would be pleased to have children. i cannot tell what is the trouble, but i lose them and i am as careful as i can be. it happens just when i am on the fourth month. i have just had my third miscarriage and been flowing over two weeks and have much pain in back and womb. my menstruation is very painful and some months i have it twice. my stomach bothers me. i suffer with indigestion and dyspepsia. mrs. frank wilcox. august 25, 1903. i will let you know that i have a son, and if it had not been for lydia e. pinkham's vegetable compound i would not have my baby. your medicine kept me well until the last minute. i did not know what an ache was. i used fourteen bottles of the compound and three boxes of your liver pills. i cannot thank your medicine too much as it has done me more good than the doctors. mrs. frank wilcox. 43 orange st., bloomfield, n. j. june 26, 1903. i have been a sufferer for seven years with womb trouble, ever since my child was born. my doctor says my ovaries are affected also and will have to be

the good of others for everyone ought to know of your wonderful medicine. mrs. j. d. curtis, box 262, monaca, pa. january 15, 1901. i was reading to-day in a paper of the recovery of a lady after writing to you and as her case seemed to be very much the same as mine, i was impressed with the desire to write to you to see if i could not get relief. i am the mother of two children and have never had any weakness of any kind until the past year. i am pregnant at present, my back pains me nearly all the time and left side of abdomen. my back pains so sometimes i cannot stand on my feet or straighten up. my appetite is poor and my friends tell me i look badly. i hope that you will be able to give me some advice. mrs. d. d. eddy. june 27, 1903. about one year and a half ago, i wrote you in regard to my taking your medicine. i was pregnant at the time and in perfect misery. i suffered everything. you very kindly wrote to me advising your lydia e. pinkham's vegetable compound which i began to take at once and when my baby was born, i was sick only half an hour and the sixth day i was upon my feet and felt as well and strong as i ever felt in my life. my baby is a strong healthy boy. i wish to thank you from the bottom of my heart for your kind letter to me. lydia e. pinkham's vegetable compound is the grandest medicine in the world for women. i shall recommend it as long as i live. mrs. d. d. eddy, 243 east ave., saratoga springs, n.y. dear mrs. pinkham: i am very grateful for the good lydia pinkham's vegetable compound did for me. i began using it when i thought there was no help for me and that i would be an invalid for life. the doctor said that i would not get well unless i underwent an operation for ovarian and female difficulties. i was afraid that my health would not stand the strain and so when a friend who was similarly afflicted told me of the good lydia pinkham's vegetable compound did her, i immediately began to use it and i am glad that i did so, for in less than four months i could report as she did a perfect cure. words fail to express my thankfulness. very truly yours, margrite ryan, hotel english, indianapolis, ind. treasurer st. andrews society. dear mrs. pinkham: last spring my health seemed gradually to decline, until i finally felt so weak i thought i would have to give up entirely. i lost my appetite, had headaches, and bearing down pains with cramps so that i was in perfect misery. i became wakeful and extremely nervous. reading of the value of lydia e. pinkham's vegetable compound in our paper here, i decided to try it, and am pleased to state that i derived immediate benefit, and soon enjoyed permanent relief. within eight weeks i was restored to normal health, and felt refreshed and strengthened as though i had enjoyed a lengthy vacation. since that time i have recommended your compound to a number of my lady friends suffering with female irregularities, and those who have used it report great benefit from its use. mrs. e. e. van dinter, 965 college ave., appleton, wis. vice-president social economic club. +lady on sofa with head obscured by pillows; child sitting on floor crying+ ~don't~ don't wait until your suffering have driven you to despair, with your nerves all shattered and your courage gone. help and happiness surely await you if you accept mrs. pinkham's advice. disease makes women nervous, irritable, and easily annoyed by children and household duties; such women need the counsel and help of a woman who understands the peculiar troubles of her sex; that woman is mrs. pinkham, who with that famous medicine, =lydia e. pinkham's vegetable compound=, has restored thousands upon thousands of sick and discouraged women to health and happiness. her address is lynn, mass., and her advice is free. write to-day, do not wait. =will not the volumes of letters from women who have been made strong by lydia e. pinkham's vegetable compound convince others of the virtues of this great medicine?= =when a medicine has been successful in more than a million cases, is it justice to yourself to say, without trying it, "i do not believe it would help me?"= =surely you cannot wish to remain weak and sick and discouraged, exhausted with each day's work. if you have some derangement of the feminine organism try lydia e. pinkham's vegetable compound. it will surely help you.= i am firmly persuaded after eight years experience with lydia e. pinkham's vegetable compound that it is the safest and best medicine for any suffering woman to use. immediately after my marriage i found that my health began to fail me. i became weak and pale with severe bearing down pains, fearful headaches and frequent dizzy spells. the doctors prescribed for me and yet i did not improve. i would at times bloat after eating and have frequent vomiting. i had acrid discharge and pains down through my limbs so i could hardly walk. it was as bad a case of female trouble as i have ever known. lydia e. pinkham's vegetable compound cured me within four months and since that time i have had occasion to recommend it to a number of patients suffering with all forms of female difficulties and i found that while it is considered unprofessional to recommend patent medicines, i could honestly recommend your vegetable compound for i have found it cures where other medicines fail. my mother and two sisters have used it also and their health has been restored and their strength renewed. it is a grand medicine for sick women. mrs. martha pohlman, 55 chester ave., newark, n. j. graduate nurse from blockley training school at philadelphia and for 6-1/2 years the chief clinic nurse at the philadelphia hospital. march 31, 1902. lydia e. pinkham's vegetable compound has done me a great deal of good. when i first had my monthly period i suffered very much. i would have such headaches, also pain in abdomen and side. was not able to go to school. after taking several bottles of your medicine i was relieved of my trouble and i am now well and enjoying good health. miss mary e. rogers, kipton, ohio. october 8, 1901. it gives me great pleasure to tell what your vegetable compound has done for me for the benefit of other suffering women. i would have been a total wreck and probably not living to-day had i not taken your medicine. my legs were so stiff and my back so sore that i could not be on my feet and at times i would have the sick headache so bad that i did not know what i was doing. i also had leucorrhoea all the time which caused me to feel very weak. i lost in flesh until i weighed only ninety-eight pounds. i was unable to carry babe to maturity. my first child being born in seven months. since taking your medicine i have had two little girls which are pictures of health and which i owe to lydia e. pinkham's vegetable compound. i have taken twelve bottles of the vegetable compound, used one box of liver pills which i found excellent to regulate the bowels. i am now in good health and weigh one hundred and twenty-five pounds. i cannot praise your medicine enough for the benefit i have derived from its use. what a blessing it is that women can consult with a lady and if every woman feels as i do, they would all consult you far and near. mrs. nelson f. spangler, center oak, pa. april 18, 1901 i will now write you a letter of gratitude for what your medicine has done for me. i suffered with very painful menstruation and could not become pregnant which was my great desire. i began the use of your medicine and after taking sixteen bottles i found myself pregnant. i continued the use of your vegetable compound and felt well all the time. last october my baby was born, it was a girl and weighed eleven and one-half pounds. it is my belief that i would never have had my baby if i had not used your medicine. i recommend lydia e. pinkham's vegetable compound to all, believing there is no better medicine for women. mrs. chas. rohde, 621 vine street, peoria, ill. i have intended for some time to write to you and tell you what lydia e. pinkham's vegetable compound has done for me. i had been feeling weak and nervous, very easily tired and had much backache. i took two bottles of your compound and felt so much better that i enjoyed, instead of dreading my household duties. i can and do gladly recommend your medicines to anyone suffering from female troubles. mrs. m. e. shepler, 17 amesbury place, cleveland, ohio. household cares +top right: lady sitting in chair with large broom in the backgroud; bottom left: lady standing with forefinger on cheek+ a sick woman's devotion to duty is a heroism which a well person cannot understand. how distressing to see a woman struggling with her daily round of household duties, when her back and head are aching, and every movement brings out a new pain. one day the poor woman is wretched and utterly miserable; in a day or two she is better, and laughs at her fears, thinking there is nothing much the matter after all; but before night the deadly backache reappears, the limbs tremble, the lips twitch--it seems as though all the imps of satan were clutching her vitals; she "goes to pieces" and is flat on her back. no woman ought to arrive at this terrible state of misery, because these symptoms are a sure forerunner of womb troubles. she must remember that =lydia e. pinkham's vegetable compound= is almost an infallible cure for all female ills, such as irregularity of periods, which cause weak stomach, sick headache, etc., displacements and inflammation of the womb, or any of the multitude of illnesses which beset the female organism. read how mrs. frake wrote to mrs. pinkham when she was in great trouble. her letter tells the result, and how a cure was effected by the use of lydia e. pinkham's vegetable compound. _read these letters from mrs. frake._ "dear mrs. pinkham:--i have read of your medicine making so many cures, and have been advised to write to you, but i feel that it is of no use. the doctor says that i have womb trouble, but he does not seem to help me a great deal. i have such a weakness across me most of the time--have backache, am very nervous, and am troubled with leucorrhoea. i am very weak, cannot walk any distance or stand long unless i ache all over. i would like to know it you think your medicine would do me any good."--mrs. samuel frake, prospect plains, n.j. "dear mrs. pinkham:--i cannot thank you enough for what =lydia e. pinkham's vegetable compound= has done for me. when i first wrote to you i had suffered for years. the doctor said i had congestion of the womb, was troubled with my kidneys and bladder, my back ached dreadfully all the time, and i suffered with bearing-down feeling, could scarcely walk about to do my own housework. i stopped doctoring with the physician and took your medicine, and am now able to do my own work, have no more backache or weakness across me, and can do all my own work. i cannot praise your medicine enough, and would advise all suffering women to try it."--mrs. samuel frake, prospect plains, n.j. the medicine that has restored a million women to health is lydia e. pinkham's vegetable compound. june 10, 1901. my daughter sixteen years old, has been in very poor health ever since the change to womanhood a year ago. she had the best of doctors but they did her little good. she complained of feeling tired all the time, did not care for anything, pain in her back, very nervous, poor in flesh and so pale. it made her tired to ride or walk any distance, could not go to school. some thought she could not live long. through the use of lydia e. pinkham's vegetable compound she is now in the best of health. i feel that your medicine saved her life. mrs. anna hughes, altmar, n. y. december 12, 1902. about a month ago i took a very bad cold and it was at time of menstruation and it stopped my menses. i began to have pains in my ovaries and at last i had inflammation of the ovaries and pain in my kidneys and bladder. i got over that but did not flow hardly any. the last time i came around i began to have that pain in my right ovary and it lasted a week and i have been flowing for a week. i would like some advice as i do not know what to think of my case. miss ruby mushrush. july 22, 1903. about three months ago the doctor turned the x-ray on me to see what was the matter and found that i had an abscess near my ovary and in a place that if it had broken would have killed me right away. the doctor's medicine did me no good, so mama went to the store and got me a bottle of lydia e. pinkham's vegetable compound. i am now so well that i can work, thanks to your medicine. it has saved me from an operation. miss ruby mushrush, east chicago, ind. february 10, 1902. as i have heard

but have also been relieved of this. i cannot praise your medicine enough. i think it is the best thing made for women. i advise, everyone who suffers with female trouble to try lydia e. pinkham's vegetable compound. mrs. annie m. wahl, bellwood, blair co., pa. october 10, 1901. i think it is my duty to let you know the good that lydia e. pinkham's vegetable compound has done for me. i think it is the best medicine in the world. i was well until i weaned my baby and then i began to bloat and had bearing down pains. i took to filling up with water in my abdomen. i had the doctor and he said it was abdominal dropsy and that not having menstruation was the cause of it. he said i would have to be tapped. he tapped me once and took eleven quarts of water from me and in a week i began to fill up again and he was waiting to tap me again. i wrote to mrs. pinkham and began to take the vegetable compound and the water began to leave me. when i had taken two bottles it had all left me and menses appeared. i now feel as well as i ever did and am able to do all my work. i feel very thankful to you. mrs. hattie riley, waterford, ohio. backache ~miss pearl ackers.~ the ordinary every-day life of most of our women is a ceaseless treadmill of work. how much harder the daily tasks become when some derangement of the female organs makes every movement painful and keeps the nervous system all unstrung. one day she is wretched and utterly miserable; in a day or two she is better and laughs at her fears, thinking there is nothing much the matter after all; but before night the deadly backache reappears, the limbs tremble, the lips twitch--it seems as though all the imps of satan were clutching her vitals, she "goes to pieces" and is flat on her back. no woman ought to arrive at this terrible state of misery, because these symptoms are a sure indication of womb diseases, and backache is merely a symptom of more serious trouble. women should remember that an almost infallible cure for all female ills, such as irregularity of periods, which cause weak stomach, sick headache, etc., displacements and inflammation of the womb, or any of the multitudes of illnesses which beset the female organism may be found in lydia e. pinkham's vegetable compound =when a medicine has been successful in more than a million cases, why should you say, "i do not believe it will help me?" if you have some derangement of the feminine organism try lydia e. pinkham's vegetable compound. it will surely help you. if there is anything in your case about which you would like special advice, write freely to mrs. pinkham, lynn, mass.; her advice is given free and will greatly help you.= "dear mrs. pinkham:--about two years ago i consulted a physician about my health, which had become so wretched that i was no longer able to be about. i had severe backache, bearing-down pains, pains across the abdomen, was very nervous and irritable, and this trouble grew worse each month. "the physician prescribed for me, but i soon discovered he was unable to help me, and i then decided to try =lydia e. pinkham's vegetable compound=, and soon found that it was doing me good. my appetite was returning, the pains disappearing, and the general benefits were well marked. "you cannot realize how pleased i was, and after taking the medicine for only three months, i found i was completely cured of my trouble, and have been well and hearty ever since and no more fear of the monthly period, as it now passes without pain to me. yours very truly, miss pearl ackers, 327 north summer st., nashville, tenn." march 10, 1902. i now write to tell you what your medicine has done for me. after my first child was born, my womb came down so far that the doctor had to replace it and it was always weak and would never stay in place. a friend told me about lydia e. pinkham's vegetable compound. i got one bottle of it without any faith at all for i was so bad, i did not think it would do as much good as she said. well, i took seven bottles and now i am entirely well. i have used the vegetable compound right along when pregnant and found it a great help, child-birth being almost painless. i have had four children and have always been able to do my work even the washing until the child was born. it certainly is a wonderful medicine for pregnant women and i would not be without it at that time. mrs. george goodchild, port kennedy, pa. june 9, 1901. i had falling of the womb and such an aching across my pelvis bone could hardly walk as the least jar hurt so. i was better before i had finished the second bottle and after taking six bottles was entirely cured. i can recommend lydia e. pinkham's vegetable compound to any one. mrs. rosa g. burton, 1006 brandywine st., phila., pa. august 19, 1902. i take great pleasure in writing to thank you for what lydia e. pinkham's vegetable compound has done for me. i suffered for years with painful menstruation, pains in the back, leucorrhoea, dizziness and nervous prostration. since taking your medicine, i feel like a new woman. i never will be without your vegetable compound and will recommend it as long as i live. hoping my testimonial may be of benefit to others, i remain, yours truly, mrs. mary brady, 1929 dumaine st., nr. prieur, new orleans, la. july 16, 1901 i have been taking lydia e. pinkham's vegetable compound for the past eight months and it has done me a great deal of good. before taking it, i suffered with my head and pains in my back and when i had my changes i suffered agony, could hardly stand on my feet. i have taken twelve bottles of the compound and to-day i am a well woman. i weighed one hundred and twenty pounds before taking it and now i weigh one hundred and forty-five. i keep a laundry and recommend your medicine to my customers. augusta bliss, 530 e. 84th st., new york, n. y. april 29, 1902. i write this letter so that all suffering women may know what your wonderful medicine has done for me. before i began taking your medicine i was very weak and not able to do anything. i had had a miscarriage and a bad flooding spell and my husband had given up all hopes of my ever getting strong again. some of my friends told me to try lydia e. pinkham's vegetable compound. i was in bed at the time. after taking a few doses i began to feel better. i have taken now three bottles and am telling my friends what it has done for me. my husband would not have me do without the medicine. mrs. george perry, box 52, fort gibson, ind. ter. june 14, 1901. when i wrote to you for advice a year and a half ago, i was confined to my bed and had just about given up hopes of ever being well again. i had heard so much about lydia e. pinkham's vegetable compound i told my husband i would like to try it. he got me a bottle and after taking two bottles i was able to get up and walk a little. my trouble was enlargement of the womb, also had ovarian trouble. i had spells of flooding nearly losing my life at monthly periods. altogether i was sick and discouraged. the pains and aches i suffered i cannot explain. i took seventeen bottles of your vegetable compound and was cured. in due time i gave birth to a nice baby girl. my baby is now six months old and so fat and healthy and i am so well, no more female trouble or pain in back. mrs. may m. morgareidge, mayoworth, wyo. fibroid tumors cured. a distressing case of fibroid tumor, which baffled the skill of boston doctors. mrs. hayes, of boston, mass., in the following letter tells how she was cured, after everything else failed, by =lydia e. pinkham's vegetable compound=. =mrs. hayes' first letter appealing to mrs. pinkham for help:= "dear mrs. pinkham--i have been under boston doctors' treatment for a long time without any relief. they tell me i have a fibroid tumor. i cannot sit down without great pain, and the soreness extends up my spine. i have bearing-down pains both back and front. my abdomen is swollen, and i have had flowing spells for three years. my appetite is not good. i cannot walk or be on my feet for any length of time. "the symptoms of fibroid tumor given in your little book accurately describe my case, so i write to you for advice."--(signed) mrs. e. f. hayes, 22 ruggles st., (roxbury) boston, mass. =note the result of mrs. pinkham's advice--although she advised mrs. hayes, of boston, to take her medicine--which she knew would help her--her letter contained a mass of additional instructions as to treatment, all of which helped to bring about the happy result.= "dear mrs. pinkham--sometime ago i wrote to you describing my symptoms and asked your advice. you replied, and i followed all your directions carefully, and to-day i am a well woman. "the use of =lydia e. pinkham's vegetable compound= entirely expelled the tumor and strengthened my whole system. i can walk miles now.

to mrs. hayes.= woman's kidney troubles. lydia e. pinkham's vegetable compound is especially successful in curing this fatal woman's disease. of all the diseases known with which the female organism is afflicted, kidney disease is the most fatal. in fact, unless early and correct treatment is applied, the weary patient seldom survives. being fully aware of this, mrs. pinkham, early in her career, gave exhaustive study to the subject, and in producing her great remedy for woman's ills--lydia e. pinkham's vegetable compound--was careful to see that it contained the correct combination of herbs which was sure to control that fatal disease, woman's kidney troubles. the vegetable compound acts in harmony with the laws that govern the entire female system, and while there are many so-called remedies for kidney troubles, lydia e. pinkham's vegetable compound is the only one especially prepared for women. the following letters will show how marvellously successful it is. oct. 17, 1901. i have noticed your advertisement in the papers of your wonderful medicine, and i wish to consult you in regard to my sickness. i have been a sufferer of female weakness for the past six months; have doctored a great deal, but it has done me no good. i have _kidney_ and _bladder_ trouble, backache, constipation, headache, terrible pains in my left side, have leucorrhoea, painful menstruation, which compels me to take my bed for two and three days; also have falling of the womb. blood is very thin. i hope to hear from you soon. mrs. w. n. matthews, 548 w. jefferson st., springfield, ill. april 15, 1902. i am almost ashamed to acknowledge the receipt of your letter received last fall. after i had doctored for a year without receiving any relief, i then wrote you for advice in regard to my sickness and began the use of your medicine. i am happy to say that i never felt better in my life than i do now. i can eat hearty, sleep well, and feel like a new woman. many thanks for your kind and highly appreciated letter. i wish every suffering woman would try lydia e. pinkham's vegetable compound. mrs. w. n. matthews, 548 w. jefferson st., springfield, ill. june 15, 1901. it affords me great pleasure to give you my testimony in regard to the value of lydia e. pinkham's valuable remedies. i suffered for some time with internal trouble, being at times unable to walk across the floor. i had weakness of the bladder and was very nervous. after taking one bottle vegetable compound i felt better. i continued its use, and after taking five bottles could walk two miles without difficulty. my health is now good and i am sixty years old. i think your vegetable compound the best medicine i have ever taken. mrs. henry gittelman, 1004 n. 6th st., reading, pa. june 26, 1901. i will write and let you know how much good lydia e. pinkham's vegetable compound has done me. i cannot express the terrible suffering i have had to endure. i was taken last may with nervous prostration; also had female trouble, liver, stomach, _kidney_ and _bladder_ trouble. i was in a terrible condition. the doctor attended me for a year, but i kept getting worse. i got so i was not able to do any work. was confined to my bed most of the time, and thought i would never be able to do anything. people thought i would not live. i decided to try your medicine. i have taken twelve bottles vegetable compound and cannot praise it too highly, for i know it will do all and even more than it is recommended to do. i tell every suffering woman about your medicine and urge them to try it. mrs. emma sawyer, conyers, ga. ~change of life~ a danger period through which every woman must pass. owing to modern methods of living, not one woman in a thousand approaches this perfectly natural change without experiencing a train of very annoying and sometimes painful symptoms. at this period a woman indicates a tendency towards obesity or tumorous growths. those dreadful hot flashes, sending the blood surging to the heart until it seems ready to burst, and the faint feeling that follows, sometimes with chills, as if the heart were going to stop forever, are only a few of the symptoms of a dangerous nervous trouble. the nerves are crying out for assistance. the cry should be heeded in time. =lydia e. pinkham's vegetable compound= was prepared to meet the needs of woman's system at this trying period of her life, and all women who use it pass through this trying period with comfort and safety. august 6, 1902. my trouble was change of life and cramping. no human tongue can describe what i suffered with the cramp. i dreaded from one time to another so much that i almost wanted to die. our family physician did everything he could for me, but i got no relief. he said if i lived to get through with the other trouble it would wear away after a time, but i had it six years, and could not walk or exercise in any way without bringing on an attack of the cramp, and i would suffer untold misery until i would be perfectly exhausted and helpless. i read in one of your little books about lydia e. pinkham's vegetable compound being good for female trouble and change of life, and thought there was no harm in trying it. so i did, and it helped me, and i was able to take walks and work some. i am very thankful for the relief your medicine has been to me. mrs. v. m. blake, deep water, w. va. dear mrs. pinkham: i began to dread the approach of change of life some years ago, as so many of my friends had been miserable for five or six years during that period and as i was not very strong and being subject to headaches and weakness, i felt that i did not have the strength to carry me through this dangerous period and had it not been for lydia e. pinkham's vegetable compound, i feel that i would not have been alive to-day. i began to take it about three years ago when i felt the change coming on and continued taking it for three months, then i did not take any for a couple of months, and began to feel so badly that i started to use it again, and then continued to take it for about six months out of every year for three years and am pleased to state that it has kept me free from sickness. very truly yours, mrs. george shepherd, berlin, wis. vice-president mothers' club. june 28, 1902. i thought i would write and state my condition to you and ask if you think you can do me any good. i am fifty-five years old, never had any children. i came here from brooklyn for my husband's health, he having consumption. i have always had good health, never any trouble with my menses, always regular until two or three months before my husband died, which was march 25, 1901. as soon as he died, i commenced and flowed constantly ever since. i know it must be the change of life. i did not worry about it for four or five months, then i had a doctor but he did me no good. i had another with the same result. last may i had to go to new york and traveling i think was too much for me as i have been worse. i saw a doctor there and he wanted me to go to the hospital and have my womb curetted, but i did not feel like having that done. i never have any pain only once in a while a little backache. please let me know if you think you can do me any good. mrs. j. j. reardon. january 18, 1903. i feel that i must write and thank you for the good you have done me. i wrote to you my case last summer. i flowed constantly for sixteen months so badly that i dared not go any where and the doctors all said an operation. nothing did me any good. as a last resort i appealed to you. i had no faith in your medicine, but thought i would try it and if it did me no good i would go to the hospital. i took two boxes of the lydia e. pinkham's compound pills and started on the third and now i am all right. i was run down, nervous, could not sleep, no appetite, but lydia e. pinkham's compound has cured me entirely. i am very grateful to you and wish that everyone afflicted as i was would try it. mrs. j. j. reardon, milford, pa. november 20, 1901. lydia e. pinkham's vegetable compound did wonders for me during the _change of life_. i was troubled with backache and headache, hot flashes and cold chills, pains in my hips, and at times would have such pains under my shoulder blades that i could hardly move for a while. i hope that other suffering women will take your medicine. many thanks for what you have done for me. mrs. sarah derfer, dundee, ohio. +ladies in profile+ tired mothers =a nervous, irritable mother, often on the verge of hysterics, is unfit to care for children; it ruins a child's disposition and reacts upon herself. the trouble between children and= their mothers too often is due to the fact that the mother has some female weakness, and she is entirely unfit to bear the strain upon her nerves that governing a child involves; it is impossible for her to do anything calmly. she cannot help it, as her condition is due to suffering and shattered nerves caused by some derangement of the uterine system with backache, headache, and all kinds of pain, and she is on the verge of nervous prostration. when a mother finds that she cannot be calm and quiet with her children, she may be sure that her condition needs attention, and she cannot do better than to take lydia e. pinkham's vegetable compound it builds up her system, strengthens her nerves, and enables her to calmly handle a disobedient child without a scene. the children will soon realize the difference, and seeing their mother quiet, will themselves become quiet. _=read what the vice-pres. of the mothers' club, at hot springs, ark., says:=_ "dear mrs. pinkham--=lydia e. pinkham's vegetable compound= will make every mother well, strong, healthy and happy. i dragged through nine years of miserable existence, worn out with pain and weariness. i then noticed a statement of a woman troubled as i was, and the wonderful results she had obtained from your compound, and decided to try what it would do for me, and used it for three months. at the end of that time i was a different woman, and the neighbors remarked it, and my husband fell in love with me all over again. it seemed like a new existence. i had been suffering with inflammation and falling of the womb, but your medicine cured that, and built up my entire system, till i was indeed like a new woman."--sincerely yours, mrs. chas. f. brown, vice-pres. mothers' club, hot springs, ark. free medical advice to women. =from a vast experience in treating female ills, extending over 20

lydia e. pinkham's vegetable compound has done for me. my trouble was misplacement of the womb, also womb was lacerated, and had inflammation of the ovaries. i went away for treatment to a specialist on female diseases and passed through twelve operations. was gone from home eight weeks and gradually grew worse and returned home to die, having given up all hope of ever getting well. my heart would stop beating at times and i became very weak, could not sit up in bed. a friend of mine brought me a bottle of the vegetable compound and i began its use and by the time i had taken half a bottle i could see that i had improved. i used in all twelve bottles of the compound and am now able to do all my house work and enjoy better health than i have in six years. i owe my life to you, for i

street, rahway, n. j. +ladies with children+ dyspepsia of women =requires treatment which acts in harmony with the female system.= a great many women suffer with a form of indigestion or dyspepsia which does not seem to yield to ordinary medical treatment. while the symptoms seem to be similar to those of ordinary indigestion, yet the medicines universally prescribed do not seem to restore the patient's normal condition. =mrs. pinkham= claims that there is a kind of dyspepsia that is caused by derangement of the female organism, and which while it causes disturbance similar to ordinary indigestion cannot be relieved without a medicine which not only acts as a stomach tonic, but has peculiar utero-tonic effects as well; in other words, a derangement of the female organs may have such a disturbing effect upon a woman's whole system as to cause serious indigestion and dyspepsia, and it cannot be relieved without curing the original cause of the trouble, which seems to find its source in the pelvic organs. as proof of this theory, we call attention to the letter from mrs. maggie wright, who was completely cured by the use of lydia e. pinkham's vegetable compound. "my dear mrs. pinkham--for two years i suffered more or less with dyspepsia, which so degenerated my entire system that i was unfit to properly attend to my daily duties. i felt weak and nervous, and nothing i ate tasted good or felt comfortable in my stomach. i tried several dyspeptic cures, but nothing seemed to help me permanently. i decided to give =lydia e. pinkham's vegetable compound= a trial, and was happily surprised to find that it acted like a fine tonic, and in a few days i began to enjoy and properly digest my food. my recovery was rapid, and in five weeks i was a different woman. seven bottles completely cured me, and a dozen or more of my friends have used it since."--mrs. maggie wright, 12 van voorhis st., brooklyn, new york. =many women were utterly discouraged, and life lacked all joy to them when they wrote mrs. pinkham, lynn, mass. they received advice which made them strong women again.= +lady sitting in chair with elbow on table and hand propped on chin+ the blues =don't wait until your sufferings have driven you to despair, with your nerves all shattered and your courage gone.= when a cheerful, brave, light-hearted woman is suddenly plunged into that perfection of misery, the blues, it is a sad picture. it is usually this way: she has been feeling "out of sorts" for some time; head has ached, and back also; has slept poorly, been quite nervous, and nearly fainted once or twice; head dizzy, and heart beats very fast; then that bearing-down feeling. her doctor says: "cheer up; you have dyspepsia; you will be all right soon." but she does not get "all right." she grows worse day by day, till all at once she realizes that a distressing female complaint is established. her doctor has made a mistake. she has lost faith in him; hope vanishes; then comes the brooding, morbid, melancholy, everlasting blues. =lydia e. pinkham's vegetable compound= instantly asserts its curative powers in all those peculiar ailments of women, and the story recited above is the true experience of hundreds of american women, whose letters of gratitude we constantly publish. =surely you cannot wish to remain weak, and sick and discouraged, exhausted with each day's work. if you have some derangement of the female organism try the remedy that has restored a million women to health=, lydia e. pinkham's vegetable compound.

physicians and gradually grew worse. about a year ago i was advised by a friend to try your sanative wash and vegetable compound, which i did. after using your vegetable compound and sanative wash i am now enjoying better health than i ever did, and attribute the same to your wonderful remedies. i cannot find words to express what a godsend your remedies have been to me. whenever i begin to feel nervous and ill, i know i have a never failing physician at hand. it would afford me pleasure to know that my words have directed my suffering sisters to the road to health and strength through your most excellent remedies. i thank you again for what your remedies have done for me. miss mary sachner, 205 e. town st., columbus, ohio. sanative wash. i am glad to state that through the use of your vegetable compound and sanative wash, etc., i am cured from the worst form of female weakness. i was troubled very much with leucorrhoea, bearingdown pains and backache. it seemed that i had no strength at all. i was in pain all over. i began to feel better after taking the first dose of vegetable compound, and am now like a new woman. i know if other suffering women would only try it, it would help them. mrs. george. w. shepard, box 127, boonville, n. y. lydia e. pinkham's blood purifier is far superior to any other known remedy for the cure of all diseases arising from impurities of the blood, such as scrofula, cancerous humor, erysipelas, rheumatism, canker, salt rheum and skin diseases. impure blood can be made rich and pure. there is no condition of the human system so uncertain or so deceptive as the condition of the blood. other disease makes itself known by aches or appearance, but the blood courses on with no sign of vitiation, carrying its poison to every nerve and fibre of the body. suddenly comes the awakening; pains that were never thought of before, ulcers or eruptions where never a pimple existed, make you ask in wonder, if not in agony, the cause. this effect may come in various ways, but the cause is always impure blood. this impurity or blood poisoning produces _rheumatism_, _debility_, _neuralgia_, _scrofula_, _mercurial or syphilitic ulcers_, _fistula_, _eruptions_, _consumption_, _scurvy_, _&c._ indigestion and biliousness. these two complaints are closely akin and generally exist together. _dyspepsia, or chronic indigestion_, is more prevalent in this country than anywhere else on the face of the earth, the chief reason being that we eat with intemperate haste, and consequently do not, as a rule, properly masticate our food. the work that should be done by the dental mill we remit to the stomach; and, as it cannot accomplish the task, the _food-grist_ is not properly ground up and applied, and the whole body--aye, every fibre and tissue of it--suffers. we need not here describe the pains and penalties of _dyspepsia_. they are within the personal experience of two-thirds of the adult population of the united states. _biliousness_ is a somewhat indefinite term, but it means, in its common acceptation, an _unnatural determination of bile to the channels of circulation_. the yellow tinge of the skin and of the white of the eyes in bilious cases is caused by the undue presence of bile in the superficial blood-vessels. a proper course of lydia e. pinkham's blood purifier, together with her celebrated liver pills, will purify the blood and drive off the bile, making you happy and pleasant, instead of grouty and disagreeable. lydia e. pinkham's blood purifier is as great a success as her celebrated vegetable compound, and may be used with great benefit in all diseases caused by impurities of the blood. do not class it with bitters of any kind. it is not a drink or an appetizer, but a _strictly medicinal preparation_. it is a powerful alterative, but a purely vegetable preparation, and may be taken without fear by any invalid. the dose is small and with good nutritious diet of any kind, avoiding highly seasoned or greasy food, you will be free from the tortures of rheumatism, clear of scrofulous sores or ulcers, and eradicate every taint, whether inherited or contracted. you will have a beautiful complexion and a soft, smooth skin, and rejoice in a healthy body and pure blood. =for sale by your druggist, $1.00 per bottle.= sept. 15, 1902. i feel it my duty to send you a testimonial and tell you how much good lydia e. pinkham's vegetable compound and blood purifier has done my daughter. she feels like a different person. her menstruation was irregular; did not come around for two months. she took some medicine from the doctor which did not help her, and he thought she would have to take treatments. she took some of your vegetable compound and now her menses are regular again and she rests well nights, which she had not been able to do for about a year. her friends all wonder at her improved looks as well as health. i never fail to recommend your medicine when i know of any woman who has female troubles. mrs. magdalena schick, washington, ill. jan. 21, 1902. i will tell you what your remedy has done for me. i was in a very bad condition with scrofula swellings around my neck. it started with a bunch on the side of my neck, and it kept growing until the whole side of my face was swollen. i had tried everything in the shape of patent medicines for five years. i had gone under an operation in one of the hospitals in boston and had them cut out. i had thirty little tubular glands taken from back of my ear down my shoulder. they looked like a bunch of grapes, and about the same size. after the cuts healed over they started to come again worse than before. after suffering so much i thought i would try lydia e. pinkham's blood purifier, and before i had taken two bottles there was a great change in the swellings. i continued its use and to-day i am a well woman. every word of this is true. i cannot speak too highly in praise of your blood purifier. mrs. w. h. haynes, 38 adams ave., everett, mass. lydia e. pinkham's liver pills are especially adapted to the needs of the stomach and liver, the derangement of which they prevent and cure. they are purely vegetable and perfectly harmless. they do not purge, gripe or weaken, but are a gentle effective laxative which stimulates the natural action of the bowels. they are excellent in conjunction with the vegetable compound; especially in those cases when the complaints that are peculiar to women are attended with constipation and sluggishness of the liver. in such cases these pills enable the vegetable compound to do its work more speedily and effectively. the enormous sale of lydia e. pinkham's liver pills has been attained purely on their merit. during the last 25 years, we have found nothing to excel them. one box contains more than three times the number of pills ordinarily sold for 25 cents and we therefor justly claim superiority both in quantity and quality. january 12, 1901. i write you these few lines to see if you can suggest some means to cure me. a little more than a year ago, i was sick with menstruation for the first time and since then i am sick all the time in some way or other. i have painful and irregular menstruation. i went to summer resorts for my health and was doctored all summer, but to no effect. i have not flowed for two months and thought i would see if you could do me any good. marion barber. may 25, 1903. about two years ago i wrote to you for advice, being troubled with irregular menstruation and womb disease. i began taking lydia e. pinkham's vegetable compound and liver pills and using the sanative wash and i am glad to say i am completely cured and have not had any sickness since. i wish to thank you for your kind advice and shall recommend your medicine to my lady friends. marion barber, 101 bracewell ave., north adams, mass. i am passing through the change of life, am suffering from extreme nervousness and depression of spirits, am very constipated and blood impoverished. i have heard so much about lydia e. pinkham's medicine i wish to give it a trial. please advise me. mrs. alice pickering, 14 george street, providence, r. i. june 29, 1900. six months ago i wrote to you stating my case. you advised me to take lydia e. pinkham's vegetable compound, blood purifier and liver pills. i followed your instructions. i never used anything in my life that benefited me so much. they are wonderful medicines. i cannot say enough in their praise. i know i should have been insane if i had not taken them. mrs. alice pickering, 14 george street, providence, r. i. important when writing to mrs. pinkham for advice and counsel, it is highly important that you should answer the following questions: =is your menstruation regular?= =is your menstruation profuse?= =is your menstruation scanty?= =is your menstruation painful?= =are you married or single?= =if married, have you borne children?= =have you any discharge from the vagina other than the courses?= =have you a free movement of the bowels daily?= =are you constipated?= =is your blood in good condition?= write out plainly all symptoms you do not understand. be sure of the strictest confidence. mrs. pinkham never betrays a trust. you can rely on her help implicitly. address your letters to "mrs. pinkham, lynn, mass." a word of warning. no other medicine in the world has received such widespread and unqualified endorsement as has lydia e. pinkham's vegetable compound. no other medicine has such a record of cures of female troubles or such hosts of grateful friends. do not be persuaded that any other medicine is just as good. any dealer who asks you to buy something else when you go into his store purposely to buy lydia e. pinkham's vegetable compound, has no interest in your case. he is merely trying to sell you something on which he can make a larger profit. he does not care whether you get well or not, so long as he can make a little more money out of your sickness. if he wished you well he would, without hesitation, hand you the medicine you ask for, and which he knows is the best woman's medicine in the world. follow the record of this medicine, and remember that these thousands of cures of women whose letters are constantly printed in this paper were not brought about by "something else," but by =lydia e. pinkham's vegetable compound, the great woman's remedy for woman's ills=. those women who refuse to accept anything else are rewarded a hundred thousand times, for they get what they want--a cure. moral--stick to the medicine that you =know= is best. =when a medicine has been successful in restoring to health more than a million women, you cannot well say without trying it, "i do not believe it will help me." if you are ill, do not hesitate to get a bottle of lydia e. pinkham's vegetable compound at once, and write mrs. pinkham, lynn, mass, u. s. a., for special advice. it is free and helpful, and will cost you nothing.= this entire book copyrighted in 1901 and 1904 by the lydia e. pinkham medicine co., of lynn, mass., u. s. a. all rights reserved and will be protected by law. ~the

one considers how prevalent epilepsy, hysteria and neurasthenia are, among all ranks and ages of both sexes, it seems remarkable some such popular book was not written long ago. i add nothing to our knowledge of these ills, my object being to put what we know into simple words, and to insist on the necessity for personal discipline being allied to expert aid. the book aims at helping, not ousting, the doctor, who may find it of use in getting his patient to see--and to act on--the obvious. "nervous disease", as here used, includes only the three diseases treated of; "neuropath"--victims of them. "advice" to a neuropath is usually a very depressing decalogue of "thou shalt nots!" if it be made clear _why_ he must _not_ do so-and-so, the patient endeavours to obey; peremptorily ordered to obey, he rebels. much sound advice is wasted for lack of an interesting, convincing, "reason why!" which would ensure the hearty and very helpful co-operation of a patient who had been taught that writing prescriptions is not the limit of a doctor's activities. many folk, with touching belief in his own claims, regard the quack as a hoary-headed sage, who from disinterested motives devotes his life to curing ailments, by methods of which he alone has the secret, at low fees. to fight this dangerous idea i have tried to show in an interesting way how science deals with nerve ills, and to prove that qualified aid is needed. suggestions and criticisms will be welcomed. i. g. briggs the university, birmingham, _june_, 1921 * * * * * "lette than clerkes enditen in latin, for they have the propertie of science, and the knowing in that facultie: and lette frenchmen in their frenche also enditen their queinte termes, for it is kyndely to their mouthes; and let us showe our fantasies in soche wordes as we lerneden of our dames tongue." --chaucer. * * * * * epilepsy, hysteria, and neurasthenia * * * * * chapter i major and minor epilepsy (_grand and petit mal_) "my son is sore vexed, for ofttimes he falleth into the fire, and ofttimes into the water."--matthew xvii, 15. "oft, too, some wretch before our startled sight, struck as with lightning with some keen disease, drops sudden: by the dread attack o'erpowered he foams, he groans, he trembles, and he faints; now rigid, now convuls'd, his labouring lungs heave quick, and quivers each exhausted limb. * * * * * "he raves, since soul and spirit are alike disturbed throughout, and severed each from each as urged above, distracted by the bane; but when at length the morbid cause declines, and the fermenting humours from the heart flow back--with staggering foot first treads led gradual on to intellect and strength."--lucretius. epilepsy, or "falling sickness", is a chronic abnormality of the nervous system, evinced by attacks of _alteration of consciousness_, usually accompanied by convulsions. it attacks men of every race, as well as domesticated animals, and has been known since the earliest times, the ancients imputing it to demons, the anger of the gods, or a blow from a star. it often attacks men in crowds, when excited by oratory or sport, hence the roman name: _morbus comitialis_ (crowd sickness). in mediæval times, sufferers were regarded with awe, as being possessed by a spirit. witch doctors among savages, and founders and expounders of differing creeds among more civilized peoples, have taken advantage of this infirmity to claim divine inspiration, and the power of "seeing visions" and prophesying. epilepsy has always interested medical men because of its frequency, the difficulty of tracing its cause, and its obstinacy to treatment, while it has appealed to popular imagination by the appalling picture of bodily overthrow it presents, so that many gross superstitions have grown up around it. the description in mark ix. 17-29, is interesting: "master, i have brought thee my son, which hath a dumb spirit. and wheresoever he taketh him, he teareth him: and he foameth, and gnasheth with his teeth, and pineth away: ... straightway the spirit tare him; and he fell on the ground, and wallowed foaming. "and he asked his father, how long is it ago since this came unto him? and he said, of a child. and ofttimes it hath cast him into the fire, and into the waters, to destroy him. "and he said unto them, this kind can come forth by nothing, but by prayer and fasting." up to the present, epilepsy can be ascribed to no specific disease of the brain, the symptoms being due to some morbid disturbance in its action. epilepsy is a "functional" disease. grand mal ("_great evil_") an unusual feeling called an _aura_ (latin--vapour), sometimes warns a patient of an impending fit, commonly lasting long enough to permit him to sit or lie down. this is followed by giddiness, a roaring in the ears, or some unusual sensation, and merciful unconsciousness. in many cases this stage is instantaneous; in others it lasts some seconds--but an eternity to the sufferer. this stage is all that victims can recall (and this only after painful effort) of an attack. as unconsciousness supervenes, the patient becomes pale, and gives a cry, which varies from a low moan to a loud, inhuman shriek. the head and eyes turn to one side, or up or down, the pupils of the eyes enlarge and become fixed in a set stare, and the patient drops as if shot, making no effort to guard his fall, being often slightly and sometimes severely injured. the whole body then becomes stiff. the hands are clenched, with thumbs inside the palms, the legs are extended, the arms stiffly bent, and the head thrown back, or twisted to one side. the muscles of the chest and heart are impeded in their action, breathing ceases, the heart is slowed, and the face becomes pale, and then a livid, dusky blue. the skin is cold and clammy, the eyebrows knit; the tongue may be protruded, and bitten between the teeth. the eyeballs seem starting from their sockets, the eyes are fixed or turned up, so that only the sclerotic ("whites") can be seen, and they may be touched or pressed without causing blinking. the stomach, bladder, and bowels may involuntarily be emptied. this _tonic_ stage only lasts a few seconds, and is followed by convulsions. the head turns from side to side, the jaws snap, the eyes roll, saliva and blood mingle as foam on the lips, the face is contorted in frightful grimaces, the arms and legs are twisted and jerked about, the breathing is deep and irregular, the whole body writhes violently, and is bathed in sweat. the spasms become gradually less severe, and finally cease. deep breathing continues for some seconds; then the victim becomes semi-conscious, looks around bewildered, and sinks into coma or deep sleep. "...as one that falls, he knows not how, by force demoniac dragg'd to earth, and through obstruction fettering up in chains invisible the powers of man; who, risen from his trance, gazeth around bewilder'd with the monstrous agony he hath indured, and, wildly staring, sighs: ..." in a few hours he wakes, with headache and mental confusion, not knowing he has been ill until told, and having no recollection of events just preceding the seizure, until reminded of them when they are slowly, and with painful effort, brought to mind. he is exhausted, and often vomits. in severe cases he may be deaf, dumb, blind, or paralysed for some hours, while purple spots (the result of internal hemorrhage) may appear on the head and neck. victims often pass large quantities of colourless urine after an attack, and, as a rule, are quite well again within twenty-four hours. this is the usual type, but seizures vary in different patients, and in the same sufferer at different times. the cry and the biting of the tongue may be absent, the first spasm brief, and the convulsions mild. epilepsy of all kinds is characterized by an _alteration_ (not necessarily a _loss_) of consciousness, followed by loss of memory for events that occurred during the time that alteration of consciousness lasted. attacks may occur by day only, by day and by night, or by night only, though in so-called nocturnal epilepsy, it is _sleep_ and not night that induces the fit, for night-workers have fits when they go to sleep during the day. victims of nocturnal epilepsy may not be awakened by the seizure, but pass into deeper sleep. intermittent wetting of the bed, occasional temporary mental stupor in the morning, irritability, temporary but well-marked lapses of memory, sleep-walking, and causeless outbursts of ungovernable temper all suggest nocturnal epilepsy. such a victim awakes confused, but imputes his mental sluggishness to a hearty supper or "a bad night". a swollen tongue, blood-stained pillow, and urinated bed arouse suspicion as to the real cause, suspicion which is confirmed by a seizure during the day. he is more fortunate (if such a term can rightly be used of any sufferer from this malady) than his fellow victim whose attacks occur during the day, often under circumstances which, to a sensitive nature, are very mortifying. epileptic attacks are of every degree of violence, varying from a moment's unconsciousness, from which the patient recovers so quickly that he cannot be convinced he has been ill, to that awful state which terrifies every beholder, and seems to menace the hapless victim with instant death. every degree of frequency, too, is known, from one attack in a lifetime, down through one in a year, a month, a week, or a day; several in the same periods, to _hundreds_ in four-and-twenty hours. petit mal ("_little evil_") this is incomplete _grand mal_, the starting stages only of a fit, recovery occurring before convulsions. _petit mal_ often occurs in people who do not suffer from _grand mal_, the symptoms consisting of a loss of consciousness for _a few seconds_, the seizure being so brief that the victim never realizes he has been unconscious. he suddenly stops what he is doing, turns pale, and his eyes become fixed in a glassy stare. he may give a slight jerk, sway, and make some slight sound, smack his lips, try to speak, or moan. he recovers with a start, and is confused, the attack usually being over ere he has had time to fall. if talking when attacked, he hesitates, stares in an absent-minded manner, and then completes his interrupted sentence, unaware that he has acted strangely. whatever act he is engaged in is interrupted for a second or two, and then resumed. a mild type of _petit mal_ consists of a temporary _blurring_ of consciousness, with muscular weakness. the victim drops what he is holding, and is conscious of a strange, extremely unpleasant sensation, a sensation which he is usually quite unable to describe to anyone else. the view in front is clear, he understands what it is--a house here, a tree there, and so on--yet he does not _grasp_ the vista as usual. other victims have short spells of giddiness, while some are unable to realize "where they are" for a few moments. frequent _petit mal_ impairs the intellect more than _grand mal_, for convulsions calm the patient as a good cry calms hysterical people. after a number of attacks of _petit mal, grand mal_ usually supervenes, and most epileptics suffer from attacks of both types. some precocious, perverse children are victims of unrecognized _petit mal_, and when pushed at school run grave risks of developing symptoms of true epilepsy. the "little evil" is a serious complaint. * * * * * chapter ii rarer types of epilepsy if it be true that: "one half the world does not know how the other half lives", how true also is it that one half the world does not know, and does not care, what the other half suffers. epilepsy shows every gradation, from symptoms which cannot be described in language, to severe _grand mal_. gowers says: "the elements of an epileptic attack may be extended, and thereby be made less intense, though not less distressing. if we conceive a minor attack that is extended, and its elements protracted, with no loss of consciousness, it would be so different that its epileptic nature would not be suspected. swiftness is an essential element of ordinary epilepsy, but this does not prevent the possibility of deliberation." in serial epilepsy, a number of attacks of _grand mal_ follow one another, with but very brief intervals between. serial epilepsy often ends in _status epilepticus_, in which a series of _grand mal_ attacks follow one another with no conscious interval. the temperature rises slowly, the pulse becomes rapid and feeble, the breathing rapid, shallow and irregular, and death usually occurs from exhaustion or heart-failure. though not invariably fatal, the condition is so very grave that a doctor must instantly be summoned. nearly all victims of severe, confirmed epilepsy (25 per cent of all epileptics) die in _status epilepticus_. jacksonian epilepsy, named after hughlings jackson, who in 1861 traced its symptoms to their cause, is not a true epilepsy, being due to a local irritation of the cortex (the outermost layer) of the brain. there is usually an _aura_ before the attack, often a tingling or stabbing pain. the chief symptoms are convulsions of certain limbs or areas of the body, which, save in very severe cases, are confined to one side, and are not attended by loss of consciousness. the irritation spreads to adjacent areas, as wavelets spread from a stone thrown into a pond, with the result that convulsions of other limbs follow in sequence, all confined to one side. as every part of the brain is connected to every other part by "association fibres", in very violent attacks of jacksonian epilepsy the irritation spreads to the other side of the brain also, consciousness is lost, the convulsions become general and bilateral, and the patient presents exactly the same picture as if the attack were due to _grand mal_. all degrees of violence are seen. the convulsions may consist only of a rapid trembling, or the limb or limbs may be flung about like a flail. jackson said: "the convulsion is a brutal development of a man's own movements, a sudden and excessive contention of many of the patient's familiar motions, like winking, speaking, singing, moving, etc." these acts are learned after many attempts, and leave a memory in certain groups of brain cells; irritate those cells, and the memorized acts are performed with convulsive violence. the convulsions are followed by temporary paralysis of the involved muscles, but power finally returns. as we should expect, this paralysis lasts longest in the muscles first involved, and is slightest in the muscles whose brain-centres were irritated by the nearly exhausted waves. if the disease be untreated, the muscles in time may become totally paralysed, wasted, and useless. friends should very carefully note exactly where and how the attack begins, the exact part first involved, and the precise order in which the spasms appear, as this is the only way the doctor can localize the brain injury. the importance of this cannot be overrated. the consulting surgeon will say if operation is, or is not, advisable, but _operation is the sole remedy for jacksonian epilepsy_, for the causes that underly its symptoms cannot be reached by medicines. patients must consult a good surgeon; other courses are _useless_. psychic or mental epilepsy is a trance-state often occurring after attacks of _grand_ or _petit mal_, in which the patient performs unusual acts. the epileptic feature is the patient's inability to recall these actions. the complaint is fortunately rare. the face is usually pale, the eyes staring, and there may be a "dream state". without warning, the victim performs certain actions. these may be automatic, and not seriously embarrassing--he may tug his beard, scratch his head, hide things, enter into engagements, find the presence of others annoying and hide himself, or take a long journey. such a journey is often reported in the papers as a "mysterious disappearance". yet, had he committed a crime during this time, he would probably have been held "fully responsible" and sentenced. the actions may be more embarrassing: breaking something, causing pain, exhibiting the sexual organs; the patient may be transported by violent rage, and abuse relatives, friends or even perfect strangers; he may spit carelessly, or undress himself--possibly with a vague idea that he is unwell, and would be better in bed. finally the acts may be criminal: sexual or other assault, murder, arson, theft, or suicide. in this state, the patient is dazed, and though he appreciates to some extent his surroundings, and may be able to answer questions more or less rationally, he is really in a profound reverie. the attack soon ends with exhaustion; the victim falls asleep, and a few moments later wakes, ignorant of having done or said anything peculiar. we usually think of our _mind_ as the aggregate of the various emotions of which we are actually _conscious_, when, in reality, consciousness forms but a small portion of our mentality, the _subconscious_--which is composed of all our past experiences filed away below consciousness--directing every thought and act. inconceivably delicate and intricate mind-machinery directs us, and our idlest fancy arises, _not by chance_ as most people surmise, but through endless associations of subconscious mental processes, which can often be laid bare by skilful psycho-analysis. our subconscious mind does not let the past jar with the present, for life would be made bitter by the eternal vivid recollection of incidents best forgotten. every set of ideas, as it is done with, is locked up separately in the dungeons of subconsciousness, and these imprisoned ideas form the basis of memory. _nothing is ever forgotten_, though we may never again "remember" it this side the grave. in a few cases we can unlock the cell-door and release the prisoner--we "remember"; in some, we mislay the key for awhile; in many, the wards of the lock have rusted, and we cannot open the door although we have the key--we "forget"; finally, our prisoner may pick the lock, and make us attend to him whether we wish to or not--something "strikes us". normally, only one set of ideas (a complex) can hold the stage of consciousness at any one time. when two sets get on the boards together, double-consciousness occurs, but even then they cannot try to shout each other down; one set plays "leading lady", the other set the "chorus belle" and so life is rendered bearable. this "dissociation of consciousness" occurs in all of us. a skilled pianist plays a piece "automatically" while talking to a friend; we often read a book and think of other things at the same time: our full attention is devoted to neither action; neither is done perfectly, yet both are done sufficiently well to escape comment. day-dreaming is dissociation carried further. "leading lady" and "chorus belle" change places for a while--imaginary success keeps us from worrying about real failure. dissociation, day-dreaming, and mental epilepsy are but few of the many milestones on a road, the end of which is insanity, or complete and permanent dissociation, instead of the partial and fleeting dissociation from which we all suffer. the lunatic never "comes to", but in a world of dreams dissociates himself forever from realities he is not mentally strong enough to face. the writing of "spirits" through a "medium" is an example of dissociation, and though shown at its best in neuropaths, is common enough in normal men, as can be proved by anyone with a planchette and some patience. if the experimenter puts his hands on the toy, and a friend talks to him, while another whispers questions, he may write more or less coherent answers, though all the time he goes on talking, and does not know what his hand is writing. his mind is split into two smaller minds, each ignorant of the other, each busily liberating memory-prisoners from its own block of cells in the gaol of the subconscious. the writing often refers to long-forgotten incidents, the experiment sometimes being of real use in cases of lost memory. dreams are dissociations in sleep, while the scenes conjured up by crystal-gazing are only waking dreams, in which the dissociation is caused by gazing at a bright surface and so tiring the brain centres, whereupon impressions of past life emerge from the subconscious, to surprise, not only the onlookers to whom they are related, but also the gazer herself, who has long "forgotten them". it is childish to attach supernatural significance to either dreams or crystal-gazing, both of which mirror, not the future, but only the past, the subject's own past. it is noteworthy that women dream more frequently and vividly than men. when a dreamer has few worries, he usually dreams but forgets his dream on waking; when greatly worried, he often carries his problems to bed with him, and recent "representative dreams" are merely unprofitable overtime work done by the brain. occasionally, dreams have a purely physical basis as when palpitation becomes transformed in a dream into a scene wherein a horse is struggling violently, or where an uncovered foot originates a dream of polar-exploration; in this latter type the dream is protective, in that it is an effort to side-track some irritation without breaking sleep. since freud has traced a sex-basis in all our dreams, many worthy people have been much worried about the things they see or do in dreams. let them remember that virtue is not an inability to conceive of misconduct, so much as the determination to refrain from it, and it may well be that the centres which so determinedly inhibit sexual or unsocial thoughts in the day, are tired by the very vigour of their resistance, and so in sleep allow the thoughts they have so stoutly opposed when waking to slip by. the man who is long-suffering and slow to wrath when awake, may surely be excused if he murders a few of his tormentors during sleep. epileptiform seizures are convulsions due to causes other than epilepsy, and only a doctor can tell if an attack be epileptic or not and prescribe appropriate treatment. to give "patent" medicines for "fits", to a man who may be suffering from lead poisoning or heart disease, is criminal. convulsions in children often occur before or after some other ailment. such children need careful training, but less than 10 per cent of children who have convulsions become epileptic. epilepsy should only be suspected if the first attack occurs in a previously healthy child of over two years of age. there are many possible causes for infantile convulsions, and but one treatment; call in a doctor _at once_, and, while waiting for him, put the child in a warm bath (not over 100° f.) in a quiet, darkened room, and hold a sponge wrung out of hot water to the throat at intervals of five minutes. never give "soothing syrups" or "teething powders". the "soothing" portion of such preparations is some essential oil, like aniseed, caraway or dill, and there are often present strong drugs unsuitable for children. according to the analyses made by the british medical association, the following are the _essential_ ingredients of some well-known preparations for children: mrs. winslow's soothing potassium bromide, syrup. aniseed, and syrup (sugar and water). woodward's gripe sodium bicarbonate, water. caraway, and syrup. atkinson and barker's pot. and magnesium royal infant bicarbonate, several preservative. oils, and syrup. mrs. johnson's american spirits of salt, common soothing syrup. salt, and honey. convulsions during pregnancy. send for a doctor instantly. feigned epilepsy is an all-too-common "ailment". the false fit, as a rule, is very much overdone. the face is red from exertion instead of livid from heart and lung embarrassment, the spasms are too vigorous but not jerky enough, the skin is hot and dry instead of hot and clammy, the hands may be clenched, but the thumb will be _outside_ instead of _inside_ the palm, foam comes in volumes but is unmixed with blood, and the whole thing is kept up far too long. almost before a crowd can gather an epileptic seizure is over, whereas the sham sufferer does not begin seriously to exhibit his questionable talents until a crowd has appeared. pressure on the eye, which will blink while the "sufferer" will swear; bending back the thumb and pressing in the end of the nail, when the hand will be withdrawn in feigned but not in true epilepsy; blowing snuff up the nose, which induces sneezing in the sham fit alone, or using a cold douche will all expose the miserable trick. it is, unfortunately, far easier to suggest than to apply these tests, for anyone foolish enough to try experiments within reach of the wildly-waving arms will probably get such a buffet as will damp his ardour for amateur diagnosis for some time. * * * * * chapter iii general remarks "do not muse at me, my most worthy friends; i have a strange infirmity, which is nothing to those that know me." "macbeth," act iii. starr's table shows that combinations of all types of epilepsy are possible, and that mental epilepsy is rare: grand mal 1150 grand and petit mal 589 petit mal 179 jacksonian 37 mental 16 grand mal and jacksonian 10 grand mal, petit mal and jacksonian 8 grand mal and mental 3 grand mal, petit mal and mental 6 petit mal and mental 2 fits by day only 660 fits day and night 880 fits by night only 380 the majority of victims have attacks both by day and by night. of 115,000 seizures tabulated by clark, 55,000 occurred during the day (6 a.m. to 6 p.m.) and 60,000 by night. the _usual course_ of a case of epilepsy is somewhat as follows: the disease begins in childhood, the first convulsion, about the age of three, being followed some twelve months later by a second, and this again by a third within a few months. then attacks occur more frequently until a regular periodicity--from one a day to one a year--is reached after about five years, and this frequently persists throughout life. the effect of epilepsy on the general health is not serious, but it has a more serious effect on the mind, for epileptic children cannot go to school (though special schools are now doing something towards removing this serious disability), and grow up with an imperfect mental training. they become moody, fretful, ill-tempered, unmanageable, and at puberty fall victims to self-abuse, which helps to lead to neurasthenia. then they may drift slowly into a state of mental weakness, and often require as much care as imbeciles. if the fits are severe from an early age, arrest of mental development and imbecility follow. if the disease be very mild in character, and especially if it be _petit mal_, the victim may be very precocious, get "pushed" at school, and later become eccentric or insane. adult victims necessarily lead a semi-invalid life, often cut off from wholesome work and from the pleasures of life, and become hypersensitive, timid, impulsive, forgetful, irritable, incapable of concentration, suspicious, show evidences of a weakened mind, have few interests, and are difficult to manage. about 10 per cent--the very severe cases--go on to insanity; either temporary attacks of mania, calling for restraint, or permanent epileptic dementia with progressive loss of mind. some victims are accidentally killed in, or die as a result of a fit; about 25 per cent--severe cases again--die in _status epilepticus_, but the majority after being sufferers throughout life are finally carried off by some other disease. there are many exceptions to this general course. some patients have attacks very infrequently, and are possessed of brilliant talent, though apt to be eccentric. others may have a number of seizures in youth, and then "outgrow" the complaint. a few victims are attacked only after excessive alcoholic or sexual indulgence, some women only during their menses, while other women are free from attacks during pregnancy, which state, however (contrary to popular belief), commonly aggravates the trouble. victims may be free from attacks during the duration of, and for some time after, an infectious disease; while spratling says that a consumptive epileptic may have no fits for months, or even years. some epileptics are normal in appearance, but many show signs of degeneration. this is common in the insane, but less frequent and pronounced in neurasthenics. an abnormal shape of the head or curvature of the skull, a high, arched palate, peculiarly-shaped ears, unusually large hands and feet, irregular teeth from narrow jaws, a small mouth, unequal length and size of the limbs, a projecting occiput, and poor physical development may be noted. these are most pronounced in intractable cases, in whom mental peculiarities are most frequently seen--either dullness, stupidity and ungovernable temper, or very marked talent in one direction with as marked an incapacity in others. in all epileptics, the pupils of the eye are larger than normal, and, after contracting to bright light soon enlarge again. the facial expression of most epileptics indicates abnormal mentality. when the seizures have been so frequent and severe as to cause mental decay, the actions are awkward, and the gait slouching and irregular. progressive poor memory is one of the first signs of intellectual damage consequent upon severe epilepsy. though the disease may occur at any age, most cases occur before the age of twenty, there being good reason to look for other causes (often syphilis) in cases which occur after that age. of 1,450 of gowers' cases, 30 per cent commenced before the age of ten; 75 per cent before twenty. in starr's 2,000 cases, 68 per cent commenced before the patient was twenty-one. according to turner, the first epoch is from birth to the age of six, during which 25 per cent of all cases commence, usually associated with mental backwardness, and some due to organic brain trouble. the second epoch is ten to twenty-two, the time of puberty and adolescence, during which time no less than 54 per cent of all cases commence. this is, _par excellence_, the age of onset of genuine epilepsy, the mean age of maximum onset being fourteen in men and sixteen in women. the remaining 21 per cent of cases occur after the age of twenty-two. in 430 cases of epilepsy in children, osler found that 230 were attacked before they reached the age of five, 100 between five and ten, and 100 between ten and fifteen. epilepsy, then, is a disease of early youth, coming on when the development and growth of the nervous and reproductive systems is taking place. during this period, causes, insignificant for stable people, may light up the disease in those of unstable, nervous constitution, a fact which explains the importance of training the child. both sexes are attacked. if we consider only cases of true idiopathic epilepsy female patients are probably in excess, but in epilepsy in adults, from all causes, males predominate. in females, the menopause may arrest the disease. in days gone by, epilepsy more rarely commenced after the age of twenty, but in these days of nerve stress it commences more frequently than formerly in people of mature age. a victim who has a fit for the first time after the age of twenty, however, should consult a nerve specialist immediately. in its early stages there are no changes of the brain due to, or the cause of, epilepsy, but in long-standing, severe cases, well-marked, morbid changes may be found. these are the effects, not the cause, of the disease, and they vary in intensity according to the manner of death and the length and severity of the malady. they probably cause the mental decay and slouching gait mentioned before. fits may suddenly cease for a long time, but they usually recur, and most patients have them more or less regularly through life. the fact that recovery is rare should not be hidden from patients and friends. perhaps 8 per cent of all classes recover--and "recovery" may only be a long interval--but 4 per cent of these are jacksonian, syphilitic or accident cases. only one victim in every thirty recovers from true epilepsy; and these are very mild cases, in which the fits are infrequent, there is no mental impairment, and bromides are well borne. the earlier the onset, the more severe and frequent the attacks, the deeper the coma, and the worse the mental decay, the poorer the outlook. _cure is exceptional_, but by vigorous treatment the severity of the malady may be much abated. _petit mal_ is no more hopeful than _grand mal_; less so in cases with severe giddiness; in all cases, the better the physical condition and digestive powers of the patient, the brighter the outlook. to sum up, epilepsy is a chronic abnormality of the higher nervous system, characterized by periodic attacks of alteration of consciousness, often accompanied by spasms of varying violence, affecting primarily the brain and secondarily the body, based on an abnormal readiness for action of the motor cells, occurring in persons with congenital nerve weakness, and leading to mental decay of various types and degrees of severity. * * * * * chapter iv causes of epilepsy "find out the cause of this effect, or rather say, the cause of this defect, for this effect defective comes by cause." "hamlet," act ii. the mechanism of the fit the brain consists of cells of _grey matter_, grouped together to form centres for thought, action or sensation, and _white matter_, consisting of nerve strands, which act as lines of communication between different parts of brain and body. the wrinkled surface (_cortex_) of the brain, is covered with grey matter, which dips into the fissures. there are also islands of grey matter embedded in the white. the front part of the brain is supposed, with some probability, to be the seat of intelligence, while a ribbon three inches wide stretched over the head from ear to ear would roughly cover the rolandic area, in which are contained the _motor cells_ through which impulse is translated to action. these motor cells are controlled by _inhibitory cells_, which act as brakes and release nerve energy in a gentle stream; otherwise our movements would be convulsive in their violence, and life would be impossible through inability usefully to direct our energy. that is how inhibition acts physically; mentally it is the power to restrain impulses until reason has suggested the wisest course. irritation of the cortex, especially the motor area, causes convulsions, and experiment has shown that epilepsy may be due to a disease or instability of certain inhibitory cells of the cortex. the motor cells of epileptics are restrained, with some difficulty, by these cells in normal times. when irritation from any cause throws additional strain on the motor cells, the defective brakes fail, and the uncontrolled energy, instead of flowing in a gentle stream through the usual channels, bursts forth in a tidal wave through other areas of the brain, causes unconsciousness, and exhausts itself in those violent convulsions of the limbs which we term a fit. the primary cause of epilepsy is an inherent instability of the nervous system. secondary causes are factors which cause the first fit in a person with predisposing nervous instability; later, the brain gets the _fit habit_, and attacks recur independently of the secondary cause. in most cases no secondary causes can be discovered, and the disease is then termed _idiopathic_, for want of an explanation. injuries to the brain may cause epilepsy, and many cases date from birth, a difficult labour having caused a minute injury to the brain. some accident is often wrongly alleged as the cause of fits, for most victims come of a bad stock, and when the first fit occurs, their relatives recollect an injury or a fright in the past, which is said to be the cause. great fright may cause epilepsy, as in the case of a nervous girl whose brother entered her room, covered with a sheet, as a "ghost", a "joke" that was followed by a fit within an hour. sunstroke may cause fits, and a few cases follow infectious diseases. alcoholism is a strong secondary factor, fits often occurring during a drinking-bout and in topers, but in many cases, drunkenness, instead of being the cause, is only the result of a lack of self-control following epilepsy. pregnancy may be a secondary cause of the malady: it may lead to more frequent and severe seizures in women who are already victims; bring on a recurrence of the malady after it has apparently been cured; or, very rarely, induce a temporary or permanent cure. epilepsy may be due to abortives. these drugs wreck the constitution of the undesired children, who contract epilepsy from causes which would not so have affected them had they started fairly. in many families, the first child, who was wanted, is normal; some or all the others, who were not desired and on whom attempts were probably made to prevent birth, are neuropaths, as are many illegitimate children. it cannot too emphatically be stated that there is no drug known which will procure abortion without putting the woman's life in so grave a danger as to prevent medical men using it; legal abortion is always procured surgically. dealing in abortifacients would be a capital offence under the laws of a rational community. self-abuse may perhaps play some part in epilepsy commencing or recurring after the age of ten. the onset of menstruation often coincides with the onset of epilepsy, and in some cases irregularity of the menses seems to be a secondary or exciting cause. exciting causes aggravate the trouble when present, causing more frequent and severe seizures. the chief are irritation of stomach and bowels (from decaying teeth, unchewed, unsuitable, or indigestible food, constipation, or diarrhoea), exhaustion, work immediately after a meal, passion or excitement, fright, worry, mental work, alcoholism, sexual excess, nasal growths, eye-strain; in short, anything that irritates brain or body. theories as to cause. epilepsy is usually classed as a _functional disorder_; that is, the brain cells are physically normal, but, for some unknown reason, they act abnormally at certain times. this term is a very loose one, and there is reason to believe that the basis of epilepsy is some obscure disease of the brain which has not been detected by present methods. the new school of psychologists regard the malady as a mental _complex_--a system of ideas strongly influenced by the emotions--the convulsions being but minor symptoms. fits are most frequent between 9-10 p.m. the hours of deepest repose. one school says this is due to anæmia of the brain during sleep. clark traces the cause to lessened inhibitory powers owing to the higher brain centres being at rest, while haig claims to have explained the high incidence at this hour by the fact that uric acid is present in the system in the greatest amount at this time. some doctors have thought, on the contrary, that _excess_ of blood in the head was the cause, but results of treatment so directed did not bear out the sanguine hopes built on the theory. the fact that convulsions occur in diabetes and alcoholism, suggested that epilepsy was due to poisons circulating in the blood, and thus irritating the brain. every act uses up cell material and leaves waste products, exactly as the production of steam uses up coal and leaves ashes. various waste products have been found in more than normal quantities in the blood of epileptics, but it is uncertain whether accumulation of waste products causes the seizure. a convincing theory must satisfactorily account for all the widely diverse phenomena seen in epilepsy, and the problem must remain largely a matter of speculation, until research work has given us a far deeper insight into the biochemistry of both the brain cells, and the germ-plasm than we have at present. * * * * * chapter v prevention of attacks in health matters, prevention is nine points of the law. some patients are obsessed by a peculiar sensation (the "aura") just before a fit. this warning takes many forms, the two most common being a "sinking" or feeling of distress in the stomach, and giddiness. the character of the aura is very variable--terror, excitement, numbness, tingling, irritability, twitching, a feeling of something passing up from the toes to the head, delusions of sight, smell, taste, or hearing (ringing, or buzzing, etc.), palpitation, throbbing in the head, an impulse to run or spin around--any of these may warn a victim that a fit is at hand. some patients "lose themselves" and make curious mistakes in talking. the warning is nearly always the same each time with the same patient, and is more common in mild than in severe cases. rarely, the attack does not go beyond this stage. when the patient becomes conscious of the aura he should sit in a large chair, or lie down on the floor, well away from fire, and from anything that can be capsized. he must never try to go upstairs to bed. some one should draw the blind, as light is irritating. if the warning lasts some minutes, the patient should carry with him, a bottle of uncoated one-hundredth-grain tabloids of nitroglycerin, replacing the screw cap with a cork, so that they can quickly be extracted. when the warning occurs, one--or two--should be taken, and the head bent forward. the arteries are dilated, the blood-pressure thus lowered, and the attack _may_ be averted. the use of nitroglycerin is based on the theory that seizures are caused by anæmia due to vasomotor constriction. success is only occasional, but this is so welcome as to justify the habitual use of the method. if the aura be brief, buy a few "pearls" of amyl nitrite, crush one in your handkerchief, and sniff the vapour. this has the same affect as nitroglycerin, but the action occurs in 15 seconds and only persists 7 minutes. a headache occasionally follows the use of these drugs, and they should not be employed without professional advice. when the warning is felt in the hand or foot, a strap should be worn round the ankle or wrist, and pulled tight when the aura commences. this sometimes aborts a fit, as biting a finger in which the aura commences may also do. if a victim feels unwell after a meal, he must never eat the next meal at the usual time, simply because it _is_ the usual time. should a patient feel unwell between, say, dinner and tea, instead of eating his tea he must empty his bowels by an enema, or croton oil (see chemist), and his stomach by drinking a pint of warm water in which has been stirred a tablespoonful of mustard powder and a teaspoonful of salt. after vomiting, drink warm water. _never attempt to empty the stomach at the onset of a definite aura_, for if the seizure occurs, the vomit will probably obstruct the trachea, and suffocate the victim. after the stomach has been empty ten minutes, the patient should take a double dose of bromides (chapter xix) and go to bed. next morning he will be well, whereas if he eats but a single piece of bread-and-butter he will probably have a fit within five minutes. unfortunately, in 60 per cent of cases, there is no warning at all, while in those cases which do exhibit an aura, the measures mentioned above more often fail than succeed. * * * * * chapter vi first-aid to victims "first-aid is the assistance which can be given in case of emergency by those who, with certain easily acquired knowledge are in a position, not only to relieve the sufferer, but also to prevent further mischief being done pending the arrival of a doctor."--dickey. _never try to cut short a fit_. placing smelling-salts beneath the nose, together with all other remedies for people who have "fainted", are useless in epilepsy. lay the patient on his back, with head slightly raised; admit air freely; remove scarf or collar and tie, unfasten waistcoat, shirt, stays or other tight garments, and if it be known or observed that the victim wears artificial teeth, remove them. if five people are at hand, let two persons grasp each a leg of the victim, holding it above the ankle and above the knee; two others should each hold a hand and the shoulder; the fifth supports the head. do not kneel opposite the feet or you may receive a severe kick. prevent the limbs from striking the floor, but _allow them full play_. if the victim rolls on his face gently turn him on his back. roll a large handkerchief up _from the side_ (not diagonally) and holding one end firmly, tie a knot in the other end, and place it between the teeth to protect the tongue; or slide the handle of a spoon or a piece of smooth wood between the teeth, and thus hold the tongue down. soft articles like cork and indiarubber should not be used, for if they are bitten through, the rear portion will fall down the throat and choke the victim. after the fit, lower the head to one side to clear any vomitus which, if left, might be drawn into the windpipe, lift the patient on to a couch, cover him warmly, and let him sleep. an epileptic's bed should be placed on the ground floor; if his bed be upstairs, it is difficult to get him there after an attack, while he may at any time fall downstairs and be killed. any effort to rouse him will only make the post-epileptic stupor more severe, but whether he sleeps or not, he must carefully be watched, for patients in this state are apt to slip away, often half-clothed, and travel towards nowhere in particular at a wonderfully rapid rate. if several fits follow one another, or if one is very long or severe, send for a doctor. when a seizure occurs in public, a constable should be summoned, who, being a "st. john" man, will be of far more use than bystanders brimming over with sympathy--_and ignorance_. if some kindly householder near by will allow the victim to sleep for an hour or two--a boon usually denied more from fear of recurrence than lack of sympathy, it is better than taking him home. if not, let someone call a cab, and deliver the victim safely to his friends. every epileptic should carry always with him a card stating his full name and address, with a request that some one present at any seizure will escort him home. if the victim wakes with a headache, give him a 10-grain aspirin powder, or a 5-grain phenalgin tablet; _never patent "cures"_. if possible, the patient should lie abed the day after a fit, undisturbed, taking only soda-and-milk and eggs beaten up in _hot_ milk. * * * * * chapter vii neurasthenia "some of your hurts you have cured, and the worst you still have survived; but what torments of mind you endured from evils which never arrived." --lowell. to-day, the need to eat forces even sensible men to live--and die--at a feverish rate. in bygone days the world was a peaceful place, in which our forefathers were denied the chance of combining exercise with amusement dodging murderous taxis; knew not the blessings of "bile beans", nor the biliousness they blessed either; they did not fall victims to "advert-diseases"; and they left the waters beneath to the fishes, and the skies above to the birds. withal they were sound trenchermen, who called their few ailments "humours" or "vapours" and knew what peace of mind meant. sixty years ago there was one lunatic in every six hundred people; to-day there is one in every two hundred. at the same time, the "neurasthenic temperament" is not altogether a modern product, for plato described it with great precision, and declared such people to be "undesirable citizens" for his ideal republic. neurasthenia is due to exhaustion and poisoning of the nervous system, the chief symptoms of which is persistent _neuro-muscular fatigue with general irritability_. its minor symptoms are almost as numerous as the various activities possible in mind and body. the predisposing cause of neurasthenia is inherited nervous instability, but among nervous diseases, neurasthenia seems the least dependent on heredity, this factor playing a less important part than exciting causes which are the sparks that fire explosive trains laid by the living, and often by the dead. worry in any form (especially when accompanied by excess of brain-work), accident-shock, sexual abuse, abuse of drink, drugs or tobacco, lack of exercise, exhausting diseases, menopause, and diseases of the womb, "society life", retirement, are the commonest exciting causes of neurasthenia; hard brain-work, unless accompanied by worry, not being injurious. the disease is more common in men than women (because of the more active part played by them in the struggle for existence), in cities than in the country, in mental than in manual workers, in the "idle rich", and in races which live feverishly, like the americans. it is rare in old age. ambition, the race for "success", the struggle to carry out projects beyond the reasonable capacity of one man, and the ceaseless work and worry with little sleep and no real rest which mark life to-day are responsible for this disease. competition has increased in all conditions of life; free course is given to ambition, individuals impose on their brains a work beyond their strength; and then comes care and perhaps reverse of fortune; and the nervous system, under the wear and tear of incessant excitation, at last becomes exhausted, the basic symptom is an inability to stand a normal amount of mental or physical strain, and shows itself in seven marked ways: 1. muscular fatigue, which is often most marked in the morning. the patient rises reluctantly, feeling as if he had not slept, is listless and "lazy", and can neither work nor play much without getting unduly tired. this weariness may pass off as the day wears on. 2. backache is often constant and annoying. it may be a pain, or a general discomfort, and may be felt anywhere in the back, the nape of the neck and down the spine being common places. the legs often "give way", and, in severe cases, patients believe they cannot stand, and become bed-ridden. under sudden excitement they may walk again, becoming "miracles of healing". these _spinal symptoms_ are common in neurasthenia following accident. 3. headache is more often an abnormal sensation than an intense pain. pulsations, feelings of distress, of lightness, fullness, heaviness and pressure are common, or a band may seem to be drawn tightly round the head across the forehead. the sensations are usually located in the back of the head, and may be accompanied by dizziness, noises in the ears, or dimness of sight. there may be a feeling of unsteadiness when walking, or a sense of being in motion when at rest. the headache varies in intensity; it is worst in the morning, is increased by thinking, diminished after eating, often improves at night, and never keeps the patient awake. 4. stomach and bowel disorders. the victim is indifferent to food, though dainties often tempt him, when he cannot face a square meal. he has a feeling of general well-being after a meal, but within an hour signs of imperfect digestion arise; he feels oppressed, and has flatulence. later, there are flushes of heat, palpitation, drowsiness, and a craving for food. constipation is usually obstinate, while diarrhoea may cause great weakness. 5. sleeplessness. some patients go to sleep readily, but after some instants wake suddenly, in a state of excitement that persists despite their efforts to calm themselves, and only at an early hour in the morning do they sleep again. other patients go to bed with the conviction they will not sleep, and are kept awake by incessant cogitation, their minds being harassed by a rapid flow of images, ideas and memories. in some cases the person is calm, his mind is at rest, yet he cannot sleep. 6. circulatory disturbances. more blood flows to an organ at work than to one at rest. in health we do not notice these changes, but in neurasthenia these internal tides are exaggerated as rushes of blood to the head, flushings of various parts, and coldness of hands and feet. heart palpitation is alarming but not dangerous, and the distended blood-vessels of the ears may set up vibrations in the drum, so that at night when the head is on the pillow, every beat of the heart is heard as a thump, which banishes sleep, and works the victim into a state of high tension. a pain in the chest, arms and elbows is often felt, limbs may swell (shown by the tightness of rings, collars, etc.) while the hands and feet are usually moist and clammy. the patient may have to empty the bladder every half-hour. disorders of menstruation are common. 7. mental fatigue. hundreds of pages would be needed to describe all the symptoms due to mental fatigue, the morbid belief that the victim has a fatal disease being very common, though his "disease" rarely makes him lie up; in the day he works, at night describes his symptoms to the home circle. the inability of most men to apply themselves steadfastly to any one set of ideas is seen in the immense popularity of music halls, cinemas, and short-story magazines, which offer a change of interest every few minutes. in normal people there is a slight consciousness of mental processes, but the mind rarely watches itself work; the neurasthenic is unable to concentrate, and gets charged with inconstancy and shiftlessness. his ideas are restive, continuous thought is impossible, and when talking he has to be "brought back to the point" many times. memory and attention flag, and he listens to a long conversation, or reads pages of a book without grasping its import, and consequently he readily "forgets" what in reality he never laboured to learn. trembling of limbs is common. he lacks initiative, and whatever course he is forced to take--after much indecision--he is convinced, a moment later, it would have been wiser to have taken the opposite one. all his acts are done inattentively. he goes to his room for something, but has forgotten what when he gets there; later, he wonders if he locked the drawer, and goes back to see. at night he gets up to make sure he bolted the door, put out the gas, and damped the fire. regret for the past, dissatisfaction with the present, and anxiety for the future are plagues common to most people, but they become acute in a neurasthenic, who reproaches himself with past shortcomings of no moment, infuriates himself over to-day's trivialities, and frets himself over evils yet unborn. such a patient is often greatly upset by a trifle, yet little affected by a real shock, which by its very severity arouses his reactive faculties which lay dormant and left him at the mercy of the minor event. he will fret over a farthing increase in the price of a loaf, but if his bank fails he sets manfully to. duty that should be done to-day he leaves to be shirked to-morrow; he is easily discouraged, timid, and vacillating. extremely self-conscious, he thinks himself the observed of all observers. if others are indifferent toward him, he is depressed; if interested, they have some deep motive; if grave, he has annoyed them; if gay, they are laughing at him; the truth, that they are minding their own business, never occurs to him, and if it did, the thought that other people were _not_ interested in him, would only vex him. he is extremely irritable (slight noises make him start violently), childishly unreasonable, wants to be left alone, rejects efforts to rouse him, but is disappointed if such efforts be not made, broods, and fears insanity. the true melancholic is convinced he himself is to blame for his misery; it is a just punishment for some unpardonable sin, and there is no hope for him in this world or the next. the neurasthenic, on the contrary, ascribes his distress to every conceivable cause save his own personal hygienic errors. a neurasthenic, if epileptic, fears a fit will occur at an untoward moment. he dreads confined or, maybe, open spaces, or being in a crowd. when he reaches an open space (after walking miles through tortuous byways in an endeavour to avoid it) he becomes paralysed by an undefinable fear, and stops, or gets near to the wall. he fears trains, theatres, churches, social gatherings, or the office. other victims fear knives, canals, firearms, gas, high places, and railway tracks, when the basic fear is of suicide. many patients have sudden impulses--on which the attention is focussed with abnormal intensity--to perform useless, eccentric, or even criminal actions; to count objects, to touch lamp-posts, to continually reiterate certain words, and so on. the victim is fully aware that there are no grounds for his panic or impulse, but though his reason ridicules, it cannot disperse, his fear, and the wretched man finds relief in sleep alone, which adds to his woes by being a coy lover. an almost invariable stage is that wherein the patient studies a patent-medicine advertisement and finds that a disease, or collection of diseases, is the root of his troubles. this alarms but interests him; he studies other advertisements, sends for pamphlets, and so becomes familiar with a few medical terms. he then takes a "treatment", and talks of his "complaint" and how he "diagnosed" it. he has become hypochondriac. he borrows a book on anatomy from the public library to discover in what part of the body his ailment is located. he draws up (or copies) a special diet-sheet, and talks of "proteids", notices a slight cloudiness in his urine, and underlines "the uric-acid diathesis" in one of his pamphlets. then his heart bumps, he diagnoses anew, and so goes on, usually ending by taking phosphorus for his "brain fag". then he finds he has a disease unknown to the faculty, which discovery interests him as intensely as it irritates his unfortunate friends. this prince of pessimists has a conviction that, compared with him, job was a happy man, and that he will go insane. he does not know that it is only when there are flaws in the brain from inheritance or organic disease that mental worry leads to lunacy; a sound brain never becomes unhinged from intellectual stress alone. books and friends are daily questioned about his "diseases", and in spite of reassuring replies, he continues to doubt, re-question and cross-examine endlessly, feeding his hopes on the same assurances, consoling himself with the same sympathies, and worrying himself with the same fears. other folk may be "nervy", he is seriously ill; he _knows_ it because he _feels_ it. he expects the greatest consideration himself, denies it to others, and then complains he is "misunderstood". "every symptom becomes magnified; the trifling ache or pain, the trivial flatulence, the disinclination or mere hesitation of the bowels to adhere to a strict schedule, all minor events such as occur to the majority of healthy men from time to time unheeded, come to be of vast importance to the psychasthenic individual." he keeps a record of hourly changes in his condition, and pesters his family doctor to death. he goes from physician to physician, from hospital to hospital. having been induced by his friends to see a specialist, he bores that good man--who knows him all too well--with a minute description of his symptoms, presenting for inspection carefully preserved prescriptions, urinary examination records, differential blood counts, and the like. coming away with precious advice, he feels he omitted to describe all his symptoms, begins to doubt if the specialist really understands _his_ case, and so the pitiful farce goes on--for years. the extraordinary fact is that while he is suffering (_sic_) from cancer, or heart disease, or bright's disease, and spasmodically from minor affections like tuberculosis, arterio-sclerosis, and liver-fluke, he is probably running a successful business. while making money he forgets his ills; the moment his attention is diverted from the "root of evil" he proceeds to further "diagnosis". in the end, he makes a pleasant hobby of his imaginary maladies, trying each patent nostrum, and giving herbalists, electric-belt men, christian scientists, and dozens of other weird "specialists" a chance to cure him. sexual neurasthenia occurs chiefly in young men given to self-abuse or sexual excesses. erections and emissions are frequent, first at night with amorous dreams, then in the day as a result of sexual thoughts; weakness and pain in the back follow, and the sexual act may become impossible. the patient usually studies a quack advertisement, and passes into the hands of men who make a living by bleeding such wretches dry. cold baths and the treatment outlined in chapter ix will cure him. course and outlook. neurasthenia is very curable. if the cause be removed, and vigorous treatment instituted, the victim may be well in a couple of months, but in most cases there are obstacles to radical treatment, and the disease drags on indefinitely. egoism, moral cowardice, and sexual excess play a part in much neurasthenia, but relatives must not forget, in their indignation at these laxities, that the patient really _is_ ill; it is unkind, unjust and useless to tell an ailing man the unpalatable truth that it is his own fault. * * * * * chapter viii hysteria "diseased nature oftentimes breaks forth in strange eruptions; ..." "king henry iv." hysteria, recorded in legend and law, in manuscript and marble, in folk-lore and chronicle, right from history's dawn, is still a puzzle of personality, and only equalled by syphilis in the protean nature of its manifestations. the sacred books of the east said delayed menstruation due to a devil was its cause; the thrashing-out of the devil its cure. chinese legends describe it, and its symptoms were ascribed by the inquisition to witchcraft and sorcery. old egyptian papyri tell how to dislodge the devil from the stomach, and there were hysteria specialists in 450 b.c. all old theories fix on the womb as the seat of the disease. the name hysteria is the greek word for womb, and 97 per cent of patients are women. a few of the very numerous modern theories may be noticed. the unconscious (or the subconscious) and the conscious are only parts of one whole. our "conscious" activities are those which have developed late in the history of the race, and which develop comparatively late in the history of the individual. the "conscious" is the product of the racial education of the "unconscious"; the first is the man, the modern, the civilized; the last is the child, the primitive, the savage. between the two there is no gulf fixed, and the oxford metaphysician need not go to timbuctoo to seek a superstitious savage; he may find one within himself. in hysteria, janet says, the field of consciousness is narrowed, and the patient lives through subconscious experiences, which she forgets when she again "comes to". she journeys back into the past, back a few years individually, back centuries or æons racially, and becomes a savage child again. normally, when anything goes wrong, or we suffer from excessive emotion, we give vent to our feelings by tears, abuse, anger, or impulsive action; in some way we "hit back", and relieve ourselves of the feeling of oppression. then we forget, which heals the sore, and closes the experience. if, at the moment, we bottle up our emotions, they obtrude later at inconvenient times until we "get them off our mind" by confiding in some one, when we get peace of mind. open confession _is_ good for the soul, and it is better to "cry your eyes out" than to "eat your heart out". there are some experiences, however, to which we cannot react by anger or confidence, and so we imprison our emotions, and try to obtain peace of mind by forgetting the irritation. freud thinks perverted sex ideas are thus repressed, and cause hysteria by coming into conflict with the normal sex life. if these old sores can be laid bare by psycho-analysis, and the mental abscess drained by confession and contrition, cure follows. the biologists consider hysteria as an adult childishness, a primitive mode of dodging difficulties. victims cannot live up to the complicated emotional standard of modern life, and so act on a standard which to us seems natural only in children and uncivilized races. savill gives the following differences between neurasthenia and hysteria: neurasthenia hysteria sex both sexes equally. 97 per cent females. age any age. first attack before page of 25. mental intellectual weakness; deficient will power, peculiarities bad memory want of control and attention. over emotions. causes overwork; dyspepsia; emotional upset or accident; shock. nervous shock. course fairly even. paroxysms. vary from hour to hour. mental mental exhaustion; emotional; wayward; symptoms unable to study; no self-analysis, restless; sad; living by irritable; not rule or reading equal to medical books; amusement. may fond of gaiety; be suicidal. sad and joyous by turns. never suicidal. general occasional giddiness; flushing; convulsions symptoms fainting rare; and fainting convulsions; common; no headache; backache; symptoms between sleeplessness; no attacks; local loss of feeling. anæsthesia or hyperæsthesia. termination lasts weeks or lasts lifetime in months. spasms. curable. temporarily curable. hysteria is a disease of youth, usually ceasing at the climacteric. social, financial and domestic worries are exciting causes, a happy marriage often curing, and an unhappy one greatly aggravating the complaint. it is most common among the races we usually deem "excitable", the slavs, latin races and jews, and is often associated with anæmia and pelvic disorders. symptoms. changeability of mood is striking. "all is caprice. they love without measure those they will soon hate without reason." sensationalism is manna to them. they _must_ occupy the limelight. pains are magnified or manufactured to attract sympathy; they pose as martyrs--refusing food at table, and eating sweets in their room, or stealing down to the larder at night--to the same end. if mild measures fail, then self-mutilation, half-hearted attempts at suicide, and baseless accusations against others are brought into play to focus attention on them. minor attacks usually commence with palpitation and a "rising" in the stomach or a lump in the throat, the _globus hystericus_, which the patient tries to dislodge by repeated swallowing. this is followed by a feeling of suffocation, the patient drags at her neck-band, throws herself into a chair, pants for breath, calls for help, and is generally in a state of great agitation. she may tear her hair, wring her hands, laugh or weep immoderately, and finally swoon. the recovery is gradual, is accompanied by eructations of gas, and a large quantity of pale, limpid, urine may be passed later. major attacks have attracted attention through all ages, ancient statues showing the same poses as modern photographs. the beginning stage--which may last a few moments or a few days--is one of mental unrest, the victim being irritable and depressed. in some cases a warning aura then occurs; clutchings at the throat, or the _globus hystericus_, palpitation, dizziness, sounds in the ears, spots dancing before the eyes, or feelings of intense "_tightness_" as if the skin is about to tear or the stomach to burst. the victim throws herself on a chair or couch, from which she slides to the floor, apparently senseless, the head being thrown back, the arms extended, the legs held straight and stiff. the face is that of a dreamer, and the crucifix position is not uncommon. this stage is a gigantic sexual stretch. next comes the convulsive stage, but the convulsions are not the true jerky movements of epilepsy, but are bilateral tossing, kicking, and rolling movements, interspersed with various irregular passionate attitudes. there is great alteration but _not loss_ of consciousness. the patient struggles with those about her, bites them, but never her own tongue, shrieks and fights, but never passes urine, throws things about, and arches the back until the body rests on head and feet (_opisthotonos_). the stretching and convulsive stages alternate, and the attack lasts a long time, being stopped by pain or by the departure of onlookers. during this stage the face may reflect the various emotions passing through the mind--with a fidelity that would rouse the envy of an irving. the patient gradually calms down, and a fit of tears or a scream ends the attack, after which the worn-out victim is depressed but not confused, though memory for the events of the attack may only be partial. the patient sometimes passes into the "dream state", described in chapter ii, for some hours or occasionally for far longer; these are the women described with much gusto in the local press as being in a trance--"the living dead". the victim of these attacks _is_ suffering from a disease, for she shows many temporary mental symptoms which could not possibly be feigned, while there is often a genuine partial forgetfulness of the incidents of an attack. she says she cannot help it; candid friends say she will not. the truth is that she cannot _will_ not to help it; for though intelligence and memory are often good and sometimes abnormal, the judgment and will are always weak--indecision, obstinacy, and doubt being common. treatment. a thorough examination by a doctor is _absolutely essential_, to prove that the patient is merely hysterical, and not the victim of unrecognized organic disease. in a few cases, skilled attention to some minor ailment will result in an apparently miraculous cure. many who habitually "go into hysterics", are merely grown-up "spoiled children", and in all cases, the basic factor is a lack of control and self-discipline. unfortunately, these tainted individuals who are so exquisitely sensitive that any reproof brings floods of tears, turn with mercurial rapidity from passionate fury to passionate self-reproach, and assuage by impassioned protestations of affection the distress they have carelessly inflicted, and, as a consequence of their momentary but undoubtedly sincere contrition, escape blame and punishment. harmful sympathy is thus substituted for helpful discipline, and the more stable members of the family are often made slaves to the whims and caprices of the hysterical member. the usual home treatment of the victim passes through various stages, and lacks persistence. violent methods are succeeded by studied indifference; and that again by reproaches and recriminations. greene's remarks are very pertinent: "the condition must be regarded as an acquired psycho-neurosis to be ameliorated, and perhaps removed, by suggestion and a complete control, which, though kind, is firm, persistent, insistent, and _lacking in every element that enters into the upbuilding of the hysterical temperament_." for anæmic patients, the following is a useful prescription: r. quininæ valerianatis gr. xx ferri valerianatis gr. xx ammon. valerianatis gr. xx misce et fiant pilulæ no. xx sig.: one or two three times a day, after meals. as far as the minor symptoms are concerned, the disease is usually chronic, for as soon as one symptom has been overcome another takes its place, and there is little hope of cure save when the case is taken vigorously in hand in childhood, treatment being best given in a home or hospital. home treatment consists in an attempt to inculcate the lost or never-acquired habit of self-control, and in the hygienic measures laid down for neuropaths in general in the rest of this book. in a major attack, _show no sympathy_. let every one leave the room, save one attendant, whom the victim knows to be of firm character, and calm but determined disposition. this attendant should get a jug of water, and threaten to douche the victim unless she makes vigorous efforts to control herself. if she cannot, or will not, _douche her_, then hold a towel over her nose and mouth, and she will perforce cease her gymnastics to breathe, though the attendant must be prepared for an outburst of abuse when she has recovered her breath. between attacks, all who are brought into contact with the victim, must adopt a tolerant but unsympathetic attitude, while efforts are made to inculcate habits of control. * * * * * chapter ix advice to neuropaths "great temperance, open air, easy labour, little care." the above quotation epitomizes the cure for neurasthenia, for as huxley said: "our life, fortune, and happiness depend on our knowing something of the rules of a game far more complicated than chess, which has been played since creation; every man, woman and child of us being one of the players in a game of our own. the board is the world, the pieces the phenomena of the universe, while the rules of the game are the laws of nature. though our opponent is hidden, we know his play is fair, just and patient, but we also know to our sorrow that he never overlooks a mistake or makes the slightest allowance for ignorance. to the man who plays well, the highest stakes are paid with that overflowing generosity with which the strong show their delight in strength. the one who plays badly is checkmated; without haste, but without remorse. ignorance is visited as sharply a as wilful disobedience; incapacity meets with the same punishment as crime." in many cases some real trouble is the best medicine for a neurasthenic, for though disaster may crush him, it is more likely to act as a spur, by diverting his thoughts from his woes, and making him fight instead of fret. since such blessings in disguise cannot be booked to order, first see a doctor. though little be physically wrong, the sense of comfort and relief from fear, which a clear idea of what _is_ wrong brings, goes a long way towards cure by giving the patient hope and confidence. having seen the doctor, assist him by carrying out the following advice as far as real limitations--not lazy inclinations--permit. do not say after reading this chapter, "i know all that"; you have to _do_ "all that", for medicine alone, whether patent or prescribed, is useless. * * * * * go for a long sea voyage, if possible. if not, get a long holiday in a quiet farmhouse, or, better still, get to the country for good, be it in never so humble a capacity, for a healthy cowman is happier than a neurasthenic clerk. the rural worker has no theatres, but he can walk miles without meeting another; he has woods to roam in, hills to climb, trees to muse under: he has ample light and air, and his is a far happier lot than that of a vainglorious but miserable, sedentary machine in a great city. the rural districts round braemar, the channel islands, cromer, deal, droitwich, scarborough, and weston-super-mare are, in general, suitable holiday resorts for neuropaths. avoid alcohol, tea, coffee, much meat, all excitement, anger and _worry_. take tickets only for comedy at the theatre, and leave lectures, social gatherings and dances alone. nerve-starvation needs generous feeding with easily digested food. drink milk in gradually increasing amounts up to half a gallon per day. if more food is needed, add eggs, custard, fruit, spinach, chicken, or fish, but do not forgo any milk. avoid starchy foods and sweets. eat only what you can digest, and digest all you eat. chew every mouthful a hundred times. this is one of the few sensible food fads. drink water copiously between meals, and take no liquid (save the milk) with them. keep the bowels open. if you _must_ "occupy your mind", take up some very simple, quiet hobby. gardening, fretwork, photography and gymnastics are not necessarily quiet hobbies. chess, billiards, and contortions with gymnastic apparatus are not to be recommended. if you _must_ read, peruse only humorous novels. never study, and leave exciting fiction and medical work alone. symptoms are the most misleading things in a most misleading world. after your evening meal, take a quiet walk, go to bed _and sleep_. you should occasionally spend from saturday midday to monday morning in bed, with blinds drawn, living on milk, seeing nobody and doing _nothing_. the deepest degradation of the sabbath is to fill it with odd jobs which have accumulated through the week. do not get out of bed too early in the morning, but rise in time to eat your breakfast slowly, attend to the toilet, and catch the car without haste. if your occupation be an indoor one, rise an hour earlier, and walk or cycle quietly to work. take a warm bath followed by a cold douche on rising. if no warm after-glow follows, use tepid water. keep your body warm; your head cool. be continent. nerve-tone and sexual delights are not compatible. matrimony, while a convenient cloak, is no excuse for lust. try suggestion for fears and impulses (see chapter xviii), for it is useless to try to "reason them out", though it is useful for a brief period each day to try deliberately to turn the mind away from the obsession, by singing or whistling, gradually prolonging the attempts. rest, to prevent the manufacture of more waste products, the elimination of those present, and the generation of nerve-strength from nourishing food are the things that cure. chapters xix and xx deal with the drug treatment. do not worry. whatever your trouble is, it is useless to "look before and after, and sigh for what is not" for the future cannot be rushed nor the past remedied. all patients reply promptly that they "can't help" worrying, when in truth they do not try. work never hurt anyone, but harassing preoccupation with problems which no amount of thought will solve drives many thousands to early graves. anger exhausts itself in a few minutes, fatigue in a few hours, and real overwork with a week's rest, but worry grows ever worse. ponder meredith's lines: "i _will_ endure; i will not strive to peep behind the barrier of the days to come." "look on the bright side!" said an optimist to a melancholy friend. "but there is no bright side." "then polish up the dull one!" was the sound advice tendered. _learn to forget_! one cannot open a periodical without being exhorted to train one's memory for a variety of reasons. the neuropath needs a system of forgetfulness. lethe is often a greater friend than mnemosyne. to brood on disappointments, failures and griefs only wastes energy, sours temper, and upsets the general health. resolve _beforehand_ that when unhappy ideas arise you will _not_ dwell on them, but turn your thoughts to pleasant trifles; take up a humorous book, or take a turn in the fresh air, and you will soon acquire the habit of laughing instead of whining at fate. to sum up: go slow! your neurons have been exhausted in your foolish attempt to "live this day as if thy last" in a wrong sense; feverish activity and unnecessary work must be abandoned to enable the nerves to recuperate. when the doctor says "rest", he means "_rest_", not change your bustle from work to what you are pleased to regard as play. so much is _absolute rest_ recognized as the foundation of treatment, that severe cases undergo the "weir-mitchell treatment". the patient is _utterly secluded_; letters, reading, talking, smoking and visits from friends are forbidden. he is put to bed, not allowed even to sit up, sees no one save nurse and doctor, is massaged, treated electrically, grossly overfed, fattened up, and freed from every care. in leaving his habitual circle, the patient escapes the too-attentive care of his relatives, and the incessant questions about his complaint with which they overwhelm him. the results of this régime with semi-insane wrecks are marvellous. it is a very drastic but very successful "rest-cure", and while it cannot be undergone at home, neurasthenics will benefit by following its principles as far as they can in their own homes. high-frequency or static electricity sometimes works wonders in the hands of a specialist, but the electric batteries, medical coils, finger-rings and body-belts so persistently advertised are _useless_. when the patient has in some measure recuperated, he may try the following exercises in mental concentration. vittoz claims good results from them, but they must be done quite seriously. 1. walk a few steps with the definite idea that you are putting forward right and left feet alternately. go on by easy stages until you concentrate on the movement of the whole body. 2. take any object in your hand, and note its exact form, weight, colour, etc. 3. look in a shop-window while you count ten, and as you walk on, try to recall all the objects therein exhibited. 4. accustom yourself to defining the sounds you hear, and concentrating on a special one, as that of a passing tram, or a ticking watch. 5. make a rapid examination several times daily of your feelings and thoughts, and try to express them definitely. 6. concentrate on the mental reproduction of a regular curve: a figure 8 placed on its side. 7. listen to a metronome, and, a friend having stopped it, mentally repeat the ticking to time. 8. whenever you handle anything, try to retain the impression of that object and its properties for several minutes, to the exclusion of other ideas. 9. concentrate on ideas of calm, and of energy controlled. 10. place three objects on a sheet of white paper. remove them one by one, at the same time effacing the impression of each one as it is removed, until the mind, like the paper, is blank. 11. efface two of the objects, and retain the impression of one only. 12. replace the impressions in your mind, but not the objects on the paper, one by one. the object of these exercises is to get your wandering mind daily a little more under control; do not exhaust yourself. after some months of treatment, ask yourself-am i able to walk ten miles with ease? when introduced to a stranger of either sex or any age, to converse agreeably, profitably and without embarrassment? to entertain visitors so that all enjoy themselves? to read essays or poetry with as much pleasure as a novel? to listen to a lecture, and be able afterwards to rehearse the main points? to be good company for myself on a rainy day? to submit to insult, injustice or petulance with dignity and patience, and to answer them wisely and calmly? when you are able to answer, "yes!" to these queries, your nerves are sound. * * * * * chapter x first steps towards health "all sick people want to get well, but rarely in the best way. a 'jolly good fellow' said: 'strike at the root of the disease, doctor!' and smash went the whisky bottle under the faithful physician's cane." in neuropaths, all irritation to the nervous system is dangerous, and must be eliminated, and to this end, eyes, ears, nose and teeth, all in close touch with nerves and brain, must be put and kept in perfect order. the eye. only 4 per cent, of people have _perfect_ sight. errors in refraction--common in neuropaths--mean that the unstable brain-cells are constantly irritated. dodd corrected eye-errors in 52 epileptics, 36 of whom showed improvement. you take your watch to a watchmaker, not a chemist; take your eyes to an oculist, and if you cannot afford to see one privately, get an eye-hospital note. (to allow a chemist or "optician" to try lenses until he finds a pair through which you "see better" is very dangerous.) then you go to a qualified optician, who makes a proper frame, and inserts the lenses prescribed. patients should inquire if the glasses are to be worn continually, or only when doing close work or reading. the ears. giddiness and other unpleasant symptoms may be due to ear trouble. if there is any discharge, buzzing or ringing, see a doctor, for if ear disease gains a firm hold it is usually incurable. the nose. neuropaths often suffer from moist nasal catarrh, or from a dry type in which crusts of offensive mucus form, the disagreeable odour of which is not apparent to the patient himself. he must pay careful attention to the general health, take nourishing food, and wash out the nose three times a day with: 1 oz. bicarbonate of soda, 1 oz. common salt, 1 oz. borax, dissolved in 1 pint hot water. for obstinate nasal trouble, consult an aural surgeon. the teeth. "most men dig their graves with their teeth."--chinese proverb. serious ills are caused by defective teeth, for microbes decompose the food left in the crevices to acid substances which dissolve the lime salts from the teeth, and this process continues until the tooth is lost. faulty teeth are common in neuropaths, and at the risk of being wearisome--and good advice is wearisome to people--patients must get proper aid, privately or at a dental hospital, from a _registered dentist_, who, like a doctor, does not advertise. teeth gone beyond recall will be painlessly extracted, those going, "stopped", and tartar or scale scraped off. if necessary, have artificial teeth, but remember that the comfort of a plate depends upon skilled workmanship, not on gold or platinum. everyone should visit the dentist as a matter of routine once a year. buy 3 ozs. precipitated chalk, 1 oz. chlorate of potash, and brush the teeth with this mixture ere going to bed; use tepid water after meals. do not brush across, but, holding the brush horizontally, brush with a circular motion, cleaning top and bottom teeth at once. use a moderately hard brush with a curved surface which fits the teeth. after each meal, it is essential to cleanse the interstices between the teeth with a quill toothpick or dental floss, never with a pin, for it is the decomposition of tiny particles that starts decay; _a tooth never decays from within_. 1½ fl. oz. glycerine, 1 fl. oz. carbolic acid, ½ fl. oz. methylated chloroform. with ten drops of this mixture in a wineglassful of tepid water, wash out your mouth and gargle your throat after every meal, sending vigorous waves between the teeth, and so removing any particles left by toothpick and brush. children should be taught these habits as soon as they can eat, for the custom of a lifetime is easy. * * * * * chapter xi digestion "we may live without poetry, music and art; we may live without conscience, and live without heart; we may live without friends, we may live without books, but civilized man cannot live without cooks." the human digestive system consists of a long tube, in which food is received, nutriment taken from it as it passes slowly downwards, and from which waste is discharged, in from sixteen to thirty hours afterwards. six glands pour saliva into the mouth, where it should be--but how rarely is--mixed with the food, causing chemical changes, and moistening the bolus to pass easily down. the acid gastric juice, of which a quart is secreted daily, stops the action of the saliva, and commences to digest the proteins, which pass through several stages, each a little more assimilable than the last. the lower end of the stomach contracts regularly and violently, churning the food with the juice, and gradually squirting it, when liquified to chyme, into the small intestine. if food is not chewed until almost liquified, the gastric juice cannot act normally, but has to attack as much of the surface of the food-lump as possible, leaving the interior to decompose, causing dyspepsia and flatulence. most people suppose the stomach finishes digestion, but it only initiates the digestion of those foodstuffs which contain nitrogen, leaving fats, starches and sugars untouched. by an obscure process, the acid chyme stimulates the walls of the bowel to send a chemical messenger, a hormone through the blood to the liver and pancreas, warning them their help is needed, whereupon they actively secrete their ferments. the secretion of the pancreas is very complex. it carries on the work of the saliva, and also splits insoluble fats into a soluble milky emulsion. fats are unaffected in the mouth and stomach, which explains why hot, buttered toast, and other hot, greasy dishes are so indigestible. the butter on plain bread is quickly cleared off, and the bread attacked by the gastric juice, but in toast or fatty dishes, the fat is intimately mixed with other ingredients, none of which can properly be dealt with. always butter toast when cold. to continue: the secretion of the pancreas also contains a very active ferment, which, on entering the bowel, meets and mixes with another ferment four times as powerful as gastric juice, which completes the digestion of the proteids. meantime, the secretions of lieberkühn's glands (of which there are immense numbers in the small intestine) are further aiding the digestion of the chyme, while the liver (the largest and most important gland in the body) sends its ferments, and the gall-bladder its bile, which further emulsifies the fatty acids and glycerin until they are ready to be absorbed. the chemically-changed chyme is now termed chyle, and is ready to be absorbed by the minute, projecting villi. the fatty portion of the chyle is absorbed by minute capillaries and ultimately mingles with the blood, which may look quite milky after a fatty meal. the remaining food is absorbed by the blood capillaries in the villi, and passes to the liver for filtration and storage. the large bowel has lieberkühn's glands, but not villi, and is relatively unimportant, though most of the water the body needs is absorbed from here. how food becomes energy and tissue we do not know. the tissues are continually being built up from assimilated food, and as constantly being burnt away, oxygen for this purpose being extracted from the air we inhale, and carried via the blood to every corner of the body. the ashes of this burning are expelled into the blood and lymph, and carried out of the body by the kidneys, lungs, skin and bowels. the product of the burning is the marvel--life; the extinction of the fire is the terror--death. energy is obtained almost solely from the combustion of fats and sugars, proteids being reconverted into albumin, and then broken down to obtain their carbon for combustion, the nitrogen being expelled, but proteids are essential for the building of the tissues themselves, the stones of the furnaces which burn up carbohydrates and fats. the time taken in the digestion of foods was first studied through a wound in the stomach of st. martin, a canadian. experiments were made with various well-masticated foods, and with similar foods placed unchewed, into the stomach through the wound, the latter experiment being carried out by millions of people at every meal, by a slightly different route. boiled food is more easily digested than fried or roasted (the frying pan should be anathema to a neuropath); lean meat than fat; fresh than salt; hot meat than cold; full-grown than young animals, though the latter are more tender; white flesh than red; while lean meat is made less, and fat meat more digestible, by salting or broiling. oily dishes, hashes, stews, pastries and sweetmeats are hard to digest. bread should be stale, and toasted crisply _right through_. the time, compared with the thoroughness of digestion, is of little importance, as it varies widely within physiologic bounds. most people fancy that the more they eat the stronger they become, whereas the digestion of all food beyond that actually needed to repair the waste due to physical and mental effort consumes priceless nerve energy, and weakens one. the greater part of excessive food has literally to be _burnt away_ by the body, which causes great strain, mainly on the muscles. the question is not: "how much can i eat?" but: "how much do i need?" * * * * * chapter xii indigestion "we know how dismal the world looks during a fit of indigestion, and what a host of evils disappear as the abused stomach regains its tone. indigestion has lead to the loss of battles; it has caused many crimes, and inspired much sulphurous theology, gloomy poetry and bitter satire."--hollander. the nervous dyspeptic suffers no marked pain, but often feels a "sinking", has no appetite, and cannot enjoy life because his stomach, though sound, does not get enough nerve-force to run it properly. a great deal of nerve-force is required for digestion, and if a man comes to the table exhausted, bolts his food, uses nerve-force scheming while he is bolting, and, immediately he has bolted a given amount, rushes off to work, digestion is imperfectly performed, nutriment is not assimilated, the nerve-force supply becomes deficient. he continues to overdraw his account in spite of the doctor's warning, and stomachic bankruptcy occurs, followed by a host of ills. nervous dyspepsia is a very obstinate complaint, but if tackled resolutely, it can to a great extent be mitigated; but let it be emphasized at once, that medicines, patent or otherwise, are useless. if dyspepsia be aggravated by other complaints, these should receive appropriate treatment, but the assertions so unblushingly made in patent-pill advertisements are unfounded. the very variety of the advertised remedies is proof of the uselessness of all. set aside certain periods three times a day for meals. fifteen minutes before meal times, sit in a comfortable chair, relax all your muscles, close the eyes, and try to make the mind a blank. _rest_! then eat the meal slowly and thoroughly. conversation may lighten and lengthen a meal, but avoid politics, "shop" and topics of that type. what is wanted at table is wit, not wisdom. water may be drunk with meals, provided it is drunk between eating, and not while masticating, for it has decidedly beneficial effects upon the digestive functions. water is usually forbidden with meals because if patients drink while eating, the water usurps the functions of saliva, and moistens the bolus, which is then swallowed with little or no mastication. if you cannot drink between mouthfuls, then drink only between meals. _never drink while food is in the mouth!_ after the meal, lie down on the right side for half an hour, _resting_, and so directing all available nerve-energy to getting digestion well under way. indifferent appetites must be tempted by wholesome dishes made up in a variety of enticing ways. fats are good, but must be taken in a tasty form. eat fruit deluged with cream. the crux of digestion is to "_chew_! chew!! and keep on chewing!!!" for until food is thoroughly masticated there will be no relief. the only part of the whole digestive process placed under the control of consciousness is mastication, and, paradoxically, it is the only part that consciousness usually ignores. a healthy man never knows he has a stomach; a dyspeptic never knows he has anything else, because he will not _eat_ his food, but throws it into his stomach as the average bachelor throws his belongings into a trunk. a varied, tasty diet, thoroughly chewed and salivated, with rest before and after meals, is the only means of curing dyspepsia, for no medicine can supply and properly distribute nerve-energy. digestive pills are all purgatives, with a bitter to increase appetite, and occasionally a stomachic, bound together with syrup or soap. practically all contain aloes, and very rarely a minute quantity of a digestive ferment like pepsin. taken occasionally as purges, most digestive pills would be useful, but none are suited to continuous use, and the price is, as a rule, out of all proportion to the primary cost, while one or two are, frankly, barefaced swindles. the analyses of the british medical association give the following as the probable formulæ for some well-known preparations: beecham's pills.............................aloes;

"alas! what things i dearly love- puddings and preserves- are sure to rouse the vengeance of all pneumogastric nerves!" --field. the man who pores over a book to discover the exact number of calories (heat units) of carbohydrates, proteins and fats his body needs, means well, but is wasting time. in theory it is excellent, for it should ensure maximum work-energy with minimum use of digestive-energy, but in practice it breaks down badly, a weakness to which theories are prone. one man divided four raw eggs, an ounce of olive oil, and a pound of rice into three meals a day. theoretically, such a diet is ideal, and for a short time the experimenter gained weight, but malnutrition and dyspepsia set in, and he had to give up. the best diet-calculator is a normal appetite, and fancy aids digestion more than a pair of scales. in spite of rabid vegetand other "arians", most foods are good (making allowances for personal idiosyncrasy) if thoroughly masticated. the oft-quoted analogy of the cow is incorrect, for herbivora are able to digest cellulose; but even cows masticate most laboriously. meat juices are the most digestion-compelling substances in existence, and a little meat soup, "oxo" or "bovril" is an excellent first course. no one needs more than three meals per day, while millions thrive on one or two only, which should be ready at fixed hours; for the stomach when habituated becomes congested and secretes gastric juice at those hours without the impulse of the will, is ready to digest food, and gets that rest between-times which is essential to sound digestion. the man who has snacks between meals, and chocolates and biscuits between snacks can never hope to get well. to eat the largest meal at midday, as is the custom of working-men, is best, provided one can take half an hour's rest afterwards. drink a pint of tepid water half an hour before every meal. if the stomach be very foul, add a teaspoonful of bicarbonate of soda to the water. the question of alcohol is a vexed one, but paul's "take a little wine for thy stomach's sake," is undoubtedly sound advice, though had paul been trained at a london hospital, he would have added "after meals". unfortunately, moderation is usually beyond the ability of the neuropath, and consequently he should be forbidden to take alcohol at all. spirits must be avoided. moderately strong, freshly made tea or coffee may be consumed in reasonable quantity. vegetable salads are excellent if compounded with liquids other than vinegar or salad oil, and of ingredients other than cucumbers, radishes, and the like. take little starchy food and sweetmeats. it may surprise those with "a sweet tooth" to learn that, to the end of the middle ages, sugar was used only as a medicine. meat must be eaten--if at all--in the very strictest moderation, and never more than once a day. eggs, fish and poultry--in moderation too--take its place. healthy children need very little meat, while it is a moot point if children of unstable, nervous build need any at all. the diet at homes for epileptics is usually vegetarian, and gives excellent results. never swallow skin, core, seeds or kernels of fruits, many of which, excellent otherwise, are forbidden because of the irritation caused to stomach and bowels by their seeds or skins. bromides are said to give better results if salt is not taken. a little may be used in cooking, if, as is usually the case, the patient has to eat at the common table, but condiments are unnecessary and often irritating to delicate stomachs. the diet of nervous dyspeptics must be very simple, and though it is trying and monotonous to forgo harmful dainties in favour of wholesome dishes, it is but one of the many limitations nature inflicts on neuropaths. many an epileptic, after believing himself cured, has brought on a severe attack by an imprudent meal. la rochefoucauld says: "preserving the health by too strict a regimen is a wearisome malady", but it is open to all men to choose whether they will endure the remedy or the disease. most men eat six times the minimum and twice the optimum quantity of food per day. for every one who starves, hundreds gorge themselves to death. "food kills more than famine", and the poor, who eat sparsely from necessity, suffer far less from gout, cancer, rheumatism and other food-aggravated diseases than the rich. most books give detailed lists of foods to be eaten and to be avoided, but this we believe is productive of little good. let the patient eat a mixed diet, well and suitably cooked, taking what he fancies in reason, masticating everything thoroughly, and gradually eliminating foods which experience teaches him are difficult for him to digest. * * * * * chapter xiv constipation "causing a symptom to disappear is seldom the cure of any ill; the true course is to _prevent_ the symptom." rings of muscle cause wormlike movements of the bowels, and so propel forward food and waste. weakening of these muscles or their nerve controls from any cause, results in a "condition of the bowels in which motions occur only when provoked by medicines or injections". in some cases though motions occur freely, food ingested is retained too long in the digestive tract. the blood extracts what water it needs from the fluid waste in the large bowel, but when the weak muscles allow this to remain too long, an excess of moisture is removed, leaving hard, dry masses, painful to pass. when the fæces reach the anus, they cause an uneasy feeling, which directs us to seek relief, but if we neglect this impulse the bowel may become so insensitive that it ceases to warn its owner of the need to evacuate. meantime, the muscles which expel the fæces get weak, so that every motion needs a strong effort of will, and much harmful straining. much misery is caused by false modesty in the presence of others. it can never be immodest to attend to the calls of nature, and such hypersensitiveness is dangerous, for rupture, piles, fissure, prolapse, fistula, are often due to straining. lack of exercise weakens the intestinal and abdominal muscles. unsuitable or imprudent foods or drinks, indigestion, excessive worry, and anything that lowers the general health tend to produce constipation. bacteria flourish freely in fæces, and though it is doubtful whether the "auto-intoxication" so freely ascribed to them, is supported by facts, it cannot be doubted that, whatever the precise mechanism by which the effects are produced, constipation does result in a lowering of the resistance to disease. more frequent fits, colic, foul breath, headache right across the forehead, lost appetite, drowsiness, skin eruptions, irritability, insomnia, melancholia and anæmia (especially the "green sickness" of women, usually connected with menstrual irregularities) are but a few of many ills partly or wholly due to or consequent upon constipation. the symptoms of constipation of the small bowel are dry stools, usually light in colour. to cure this type, more water should be drunk, so that the waste may pass to the large bowel in a fluid state. drink freely between meals, especially in summer, when profuse perspiration often causes obstinate constipation. the symptoms of constipation of the large bowel are furred tongue, foetid breath, sallow or jaundiced complexion, and mottled stools of round, hard balls, the first portion being very firm, and the remainder nearly liquid. there are occasional attacks of colic. the first step towards cure is to form regular habits. at a suitable time, say shortly after breakfast, or after supper if you suffer from hæmorrhoids, go to the lavatory, whether you feel uncomfortable or not. wait patiently, do not try to hasten matters by violent straining, and if for some weeks there is little improvement, do not despair, for the habits of a lifetime are not overcome in five minutes, just because you have decided to amend your careless ways. a short, brisk walk beforehand often helps. if necessary, use a chamber and "squat" as savages do. in this position, the thighs support the abdomen, and force is exerted without straining. massaging the abdomen by firmly rubbing it round and round, clockwise, with the hand, often does good, as does pressure with a finger on the flesh between the end of the backbone and the anus. try every method before taking purgatives, for with patience and determination these are rarely necessary. carefully cooked and "concentrated", easily digested and "pre-digested" foods contain little residue; every meal should contain some indigestible matter to stimulate the intestines. brown bread, porridge, lettuce, cress, apples and coarse vegetables are all good for this purpose, but if taken too freely may cause heartburn and flatulence. meat, milk, fish, eggs and most patent foods have not enough waste. boiled milk is very constipating. purgatives, injections and medicines, alone, are useless, for the bowel becomes still more insensitive to natural calls under the artificial stimulation of drugs, on which it becomes so entirely dependent that without their aid it will not act. it may be necessary to clean out the bowel by an enema. make a lather with clean warm water and plain soap, and fill the enema syringe (a half-pint size is useful). smear the nozzle with vaseline, lean forward and insert into the anus, pointing a little to the left. press the bulb, withdraw the nozzle, retain the liquid a few moments and a desire to go to stool will be felt. a simpler plan is to buy glycerin suppositories. one is inserted into the anus and acts like an injection. it must be clearly understood that these are emergency measures. if internal piles come down at stool, do not allow them to remain and get engorged with blood. see that your hands are scrupulously clean, and your nails closely cut and free from dirt; then moisten the middle finger with a little vaseline taken to the lavatory for the purpose, and gently return the hæmorrhoids, sitting down for a few minutes to retain them. a mild purge may be taken once a week with advantage. glauber's salts (sodium sulphate), cascara sagrada, and liquid paraffin are all good, while castor oil globules are suited for children. for flatulence, take a 10-minim capsule of terebine after meals, or charcoal, either as french rusks ("biscols fraudin") or a teaspoonful of powdered charcoal between meals. one drop of creosote on a lump of sugar, peppermint water, and sal volatile may also be used. sufferers should toast bread, and use sugar sparingly. patent medicines almost invariably contain a brisk aperient. * * * * * chapter xv general hygiene "better to hunt in fields for health unbought, than fee the doctor for a nauseous draught." --dryden. if men but realized what complicated machines they were, they would use themselves better. in the body are 240 bones and hundreds of muscles. the heart, no bigger than the clenched fist, beats 100,000 times a day; the aerating surface of the lungs is equal in area to the floors of a six-roomed house, and by means of its minute blood-vessels which would stretch across the atlantic, 500 gallons of blood are brought into contact with over 3,000 gallons of air every day. seven million sweat-glands, 30 miles long, get rid of a pint of liquid and an ounce of solid waste each day while it takes a tube 30 feet long, with millions of glands, to deal with a sip of milk. man's finest steam engine turns one-eighth of the energy supplied into work; nature's engine, muscle, turns one-third into work. the body contains 9 gallons of water, enough carbon to make 9,000 lead pencils, phosphorus for 8,000 boxes of matches, iron for 5 tacks, and salt enough to fill half a dozen salt-cellars. over 40 food-ferments have been found in the liver; there are 5,000,000 red and 30,000 white blood corpuscles in a space as big as a pin's head, each one of which travels a mile a day and lives but a fortnight, millions of new ones being built up in the bone-marrow every second; a flash of light lasting only one eight-millionth of a second, will stimulate the eye, which can discriminate half a million tints. the ear can distinguish 11,000 tones, and is so sensitive that we hear waves of air less than one sixty-thousandth of an inch long; a mass of almost liquid jelly--for 81 per cent of the brain is water, and aristotle thought it was a wet sponge to cool the hot heart--sends out impulses ordering our every thought and act, and stores up memory, we know not how or where. there are 10,000,000,000 of cells in the brain cortex alone, and 560,000 fibres pass from the brain down the spinal cord. a clear, watery cell, no larger than the dot on an "i" encloses factors causing genius or stupidity, honesty or roguery, pride or humility, patience or impulsiveness, coldness or ardour, tallness or shortness, form of head or hands, colour of eyes and hair, male or female sex, and the thousand details that make a man. yet man uses this marvellous mechanism but carelessly, and the widespread poverty, the worry and discord in the lives of the happiest, our ignorance, the evil habits we contract, and the vice, miseries, diseases and labours to which most expectant mothers are too often exposed, explain why one baby in every eight never walks; why but four of them live to manhood; why less than 40 years is now man's average span; and why this brief space is filled with suffering and misery, from which many escape by self-destruction. sound children do not come from unclean air, surroundings, habits, pursuits, passions and parents. children conceived in unsuitable surroundings by unsuitable parents, die; must die; ought to die. they are not built for the stern battle of life. * * * * * "where the sun does not enter, the doctor does!" --italian proverb. plenty of fresh, clean air is essential to health. in all rooms a block of wood nine inches high should be inserted beneath the whole length of the bottom sash of the window. this leaves a space between the top and bottom sashes through which fresh air passes freely, without draught, both night and day, for it should never be closed. a handy man will fit a simple device to prevent the windows being forced at night, but better let in a burglar than keep out air. if it be cold or draughty in the bedroom, hang a sheet a foot from the window, put more blankets or an overcoat on the bed, or put layers of brown paper above the sheets, _but never close the window_. you can take too much of many good things, but never too much pure air. cleanliness. keep the body clean by taking at least one hot bath per week; per day if possible. much filth is excreted by your sweat-pores; why let it cake on skin and underlinen, and silently silt up your thirty miles of skin canals, thus overworking the other excretory organs, and gradually poisoning yourself? neuropaths always suffer from sluggish circulation of the extremities, and to improve this, hot and cold baths, spinal douches and massage are excellent. a hot bath (98-110° f.) ensures a thorough cleansing, but it brings the blood to the surface, where its heat is quickly lost, enervating one, and causing a bout of shivering which increases the production of heat by stimulating the heat-regulating centre in the brain. baths above 110° f. induce faintness. to prevent shivering, take a cold douche after the hot bath, and have a brisk rub down with a coarse towel, when a delightful, warm glow will result. do not freeze yourself, or the reaction will not occur; what is wanted is a short, sharp shock, which sends the blood racing from the skin, to which it returns in tingling pulsations, which brace up the whole system. the douche is over in a few seconds, and may be enjoyed the year round, commencing in late spring. the cold bath must not be made a fetish. if the glow is not felt, give it up, and bathe in tepid (85-92° f.) or warm (93-98° f.) water. when started in the vigour of youth, the cold bath may often be continued through life, but it is unwise to commence in middle life. parents should never force their children to take cold baths, to "harden them". other hygienic points. tobacco is undesirable for neuropaths, save in moderation. clothes should be light, loose, and warm. epileptics should wear low, stiff collars, half a size too large, with clip ties. such a combination does not form a tight band round the neck, and can quickly be removed if necessary. wear thick, woollen socks, and square-toed, low-heeled, double-soled boots. hats should be large, light, and of soft material. woollen underwear is best. change as often as possible, and aim at health, not appearance. let all rooms be well lighted, well ventilated, moderately heated, and sparsely furnished with necessities. shun draperies, have no window boxes, cut climbing plants ruthlessly away from the windows, and never obstruct chimneys. buy muller's "my system", which gives a course of physical exercises without apparatus, which only take fifteen minutes a day. the patient must conscientiously perform the exercises each morning, not for a week, nor for a month, but for an indefinite period, or throughout life. finally, remember that so few die a natural death from senile decay because so few live a natural life. * * * * * chapter xvi sleeplessness "o magic sleep! o comfortable bird that broodest o'er the troubled sea of the mind till it is hushed and smooth." --keats. some men need only a few hours' sleep, but no one ever overslept himself in natural slumber. there are anecdotes of great men taking little sleep, but their power usually consisted in going without sleep for some days when necessary, and making up for it in one long, deep sleep. neuropaths require from 10-13 hours to prepare the brain for the stress of the next day, but quality is more important than quantity. patients go to bed tired, but cannot sleep; fall asleep, and wake every other hour the night through; sleep till the small hours, and then wake, to get no more rest that night; only fall asleep when they should be rising; or have their slumber disturbed by nightmare, terrifying dreams, heart palpitation, and so on. noise often prevents sleep. a clock that chimes the quarters, or a watch that in the silence ticks with sledge-hammer beats, has invoked many a malediction. traffic and other intermittent noises are very trying, as the victim waits for them to recur. townsmen who seek rural quiet have got so used to town clatter, that barking dogs, rippling streams, lowing cows, rustling leaves, singing birds or chirruping insects keep them awake. too much light, eating a heavy supper, all tend to banish repose, as do also violent emotions which produce toxins, torturing the brain and causing gruesome nightmares. grief and worry--especially business and domestic cares--constipation, indigestion, bad ventilation, stimulants, excitement and a hearty supper are a few of the many causes of insomnia. in children sleeplessness is often due to the bad habit of picking a child up whenever it cries, usually from the pain of indigestion due to having been given unsuitable food. feed children properly, and train them to regular retiring hours. school home-work may cause insomnia; if so, forbid it. man spends a third of his life in the bedroom, which should be furnished and used for no other purpose. pictures, drapery above or below the bed, and wallpaper with weird designs in glaring colours are undesirable. the wall should be distempered a quiet green or blue tint, and the ceiling cream. a bedroom should never be made a storeroom for odds and ends, nor is the space beneath the bed suitable for trunks; least of all for a soiled-linen basket. some time before retiring, excitement and mental work should be avoided. the patient should take a quiet walk after supper, drink no fluid, empty bladder and bowels, and take a hot foot-bath. retire and rise punctually, for the brain, like most other organs, may be trained to definite habits with patience. if sleeplessness be ascribed, rightly or wrongly, to an empty stomach, a glass of hot milk and two plain biscuits should be taken in bed; dyspeptics should take no food for three hours before retiring. if the patient wakes in the early morning he may find a glass of milk (warmed on a spirit-stove by the bedside) and a few plain biscuits of value. a victim of insomnia should lie on his side on a firm bed with warm, light coverings, open the window, close the door, and endeavour to fix his attention on some monotonous idea; such as watching a flock of white sheep jump a hedge. think of trifles to avoid thinking of troubles. how often do we hear people complain that they suffer from insomnia, when in fact they get a reasonable amount of sleep, and indeed often keep others awake by their snoring. when you wake, _get up_, for a second sleep does no good. when some one, on seeing the narrow camp-bed in which wellington slept, said: "there is no room to turn about in it," the iron duke replied: "when a man begins to turn about in his bed it is time he turned out of it." the only safe narcotic is a day's hard work. for severe insomnia consult a doctor; do not take drugs--that way lies ruin. by taking narcotics, or patent remedies containing powerful drugs, you will easily get sleep--for a time only--and then fall a slave to the drug. such victims may be seen in dozens in any large asylum. * * * * * chapter xvii the effects of imagination "the surest way to health, say what they will is never to suppose we shall be ill; most of the ailments we poor mortals know from doctors and imagination flow." --churchill. "men may die of imagination, so depe may impression be take." --chaucer. "suggestion is the introduction into the mind of a practical belief that works out its own fulfilment."--guyau. man suffers from no purely imaginary ills, for mental ills are as real as physical ills, and though an individual be ailing simply because he persuades himself he is ailing, his mind so affects his body that he is actually unwell physically, though the cause of his trouble is purely mental. the suffering of this world is out of all proportion to its actual disease, many people being tortured by fancied ills. some dread a certain complaint because a relative has died of it. others are unwell, but while taking proper treatment they brood gloomily, and get worse instead of better as they should and _could do_. cheap medical and pseudo-medical works are not an unmixed blessing, for many a person who knows, and needs to know, nothing about disease, gets hold of one, and soon has most of the ills known to the faculty and some which are not. if a patient be an optimist and persuades himself he is improving, he _does_ improve. this is the explanation of "faith moving mountains", for the curative power of prayer, christian science, laying-on of hands, suggestion treatment and patent medicine, depends on man's own faith, not on the supernatural. a doctor in whom a patient has perfect confidence, will do him far more good with the same medicines, or even with no medicines at all, than one of riper experience in whose skill he has no faith. eloquent, though often inaccurate accounts of the benefits derived from patent medicines are persistently advertised until the mind is so influenced by the constant reiteration of miraculous cures, that, either because the healing forces of the body are thereby stimulated, or because the disease is curable by suggestion, the patient is benefited by such medicines. thinking of pain makes it worse and vice versa. the curative effects of auto-suggestion were demonstrated at the siege of breda in 1625. the garrison was on the point of surrender when a learned doctor eluded the besiegers, and got in with some minute phials of an extraordinary eastern elixir, one drop of which taken after each meal cured all the ills flesh was heir to; two drops were fatal. the "learned doctor" was a quick-witted soldier, and the elixir was _coloured water_ sold by order of the commander. its potency was due to the faith of all, who persuaded each other they were getting better, and an epidemic of infectious wellness followed ills due to depressed spirits. one man after reading a list of symptoms said in great alarm: "good heavens. i have got that disease!" and, on turning the page, found it was... _pregnancy_. as the great scotch physiologist, reid, said seventy years ago: "hope and joy promote the surface circulation of the body, and the elimination of waste matter and thus make the body capable of withstanding the causes which lead to disease, and of resisting it when formed. grief, anguish and despair enfeeble the circulation, diminish or vitiate the secretions, favour the causes which induce disease, and impede the action of the mechanism by which the body may get rid of its maladies. an army when flushed with victory and elated with hope maintains a comparative immunity from disease under physical privations and sufferings which, under the opposite circumstances of defeat and despair, produce the most frightful ravages." the classic description of the woeful effects of imagination is in jerome's "three men in a boat". harris, having a little time on his hands, strolls into a public library, picks up a medical work, and discovers he has every affliction therein mentioned, save housemaid's knee. he consults a doctor friend and is given a prescription. after an argument with an irate chemist, he finds he has been ordered to take beefsteak and porter, and not meddle with matters he does not understand. a sounder prescription never was penned. * * * * * chapter xviii suggestion treatment "to purge the veins of melancholy, and clear the heart of those black fumes that make it smart; and clear the brain of misty fogs which dull our senses, our souls clog." --burton. hypnosis and suggestion have suffered from those people who put back every reform many years--quacks and cranks--for while science, with open mind, was testing this new treatment, the quacks exploited it up hill and down dale. yet there is nothing supernatural in suggestion, for we employ it on ourselves and others every hour we live. conscience consists only of the countless stored-up suggestions of our education, which by opposing any contrary suggestions, cause uneasiness. many of us conform through life to the suggestions of others, affection, awe, hero-worship and fear taking the place of reason. the most resolute of men are influenced by tactful suggestions, which quietly "tip-toe" on to the margin of consciousness, awaken ideas which link up more and more associations, until an avalanche is started which forces itself on to the field of consciousness, the subject thinking the idea is his own. author and actor try by suggestion to make us think, laugh, or weep at their will, books are sold by suggestive titles, and many clothes are worn only to suggest wealth or respectability. the best salesman is he who by artful suggestion sells us what we do not want; the best buyer he who by equally astute suggestion makes the seller part at a price which makes him regret the bargain the moment it is closed. suggestion treatment is of great use in curing nervous states and bad habits, and all neuropaths should practice selfor auto-suggestion. in severe cases a specialist must give the treatment. the patient is taken by the neurologist to a cosy, restfully-furnished, half-lighted room, and placed in a huge easy chair facing a cheery fire. he sinks into the depths of the chair, relaxes every muscle, allows his thoughts to wander pleasantly, and soon his brain is at rest, and his mind, undisturbed by the fears which usually harass it, is ready to receive suggestions. the doctor talks quietly, soothingly, but with the conviction born of knowledge to the patient about his trouble, assuring him that he _can_ control his cravings; that he _can_ put away the doubts or fears that have grown upon him. the true reason of his illness is pointed out, any little organic factors given due weight, and the idea that it is hereditary or due to fate dispelled. faults of character, reasoning and living are unsparingly exposed and appropriate remedies suggested, and he is shown how unmanly his self-torturing reproaches are, and how futile is remorse unless transmuted into reform. the doctor's earnestness inspires confidence, and the patient unburdens his secret troubles, discusses means of remedying them, and turns from pain to promise, from remorse to resolve, from introspection to action, from dreading to doing. struck by the way the psycho-analyst reads his soul and lays bare petty meannesses, impressed by the patient thoroughness with which the doctor attends to each little symptom, confident that organic troubles--if there be any--will receive appropriate treatment, ready to carry out instructions, and disposed to believe the new treatment is of real value: under all these circumstances, the physician's suggestions carry very great weight with the patient. the resolutions passed by the victim in this calm state sink deep into subconsciousness, and when next temptation, impulse or fear assails him, his own resolutions and the doctor's suggestions are so vividly recalled that he tries to control his thoughts, and, in due time he "wins out". anyone may induce the calm state, and repeat suitable suggestions. the patient should go to a quiet room, and, reclining on a comfortable couch before a cheery fire, close the eyes, relax the muscles, breathe deeply, and avoid all sense of strain. the next step is to fix the imagination on some scene which suggests tranquility--smooth seas, autumnal landscapes, snow-clad heights, old-world gardens, deep, shady silent pools, childhood's lullabies, secluded backwaters, dim aisles of ancient churches. after a few evenings' practice, you will be able gradually to exclude all other ideas, and focus on one, inducing a state which, somewhat similar outwardly, is free from the excitement of religious exaltation, and from the delusions of a medium's trance. in this state, an appropriate suggestion must be made, sincerely, and with _absolute faith_ in its power. christ's miracles were the result of suggestive therapeutics, and he took care to inspire relatives with faith, to exclude scoffers, to surround himself by his believing apostles, and, after treatment, said: "see thou tell no man!" well knowing that suggestion cannot withstand derision. in this way, a patient of limited means can do for himself exactly what more fortunate ones pay large fees to specialists to do for them. the treatment is uncommon, but sound, for the medical profession is perhaps the most conservative on earth, and when specialists of repute use a method, you may be confident it is of value. to cure sleeplessness, see that stomach and brain are at rest, bed comfortable, and feet warm; calm yourself, and focus on the idea of sleep, saying: "i shall go to sleep in a few minutes, and wake at eight o'clock in the morning." repeat this a few times, persist for a few nights and you will quickly get drowsy, and fall asleep. phrases for other requirements will readily occur, as: "i shall feel confident in open spaces!" "i shall find no more pleasure in alcohol!" and so on. suggestion will not cure epilepsy, hysteria or neurasthenia, but it overcomes many of the symptoms which make the patient so wretched.

the nature of each herb, to know which cures and which can kill." --dryden. so distressing a malady as epilepsy early attracted attention, and every treatment superstition could devise, or science could suggest, has been tried. culpepper in his "herbal" (300 years old), recommends bryony; lunar caustic (nitrate of silver) was extensively used, because silver was the colour of the moon, which caused madness. the royal touch for scrofula (king's evil) was also extended to epilepsy, the king blessing a ring, which was worn by the sufferer. another old remedy was to cut off a lock of the victim's hair while in a seizure and put it in his hand, which stopped (?) the attack. in berkshire a piece of silver collected at the communion service and made into a ring was specific, but in devon a ring made of three nails from an old coffin was preferred. lupton says: "a piece of child's navel-string borne in a ring is good against falling sickness." nearly every drug in the pharmacopoeia has been tried, the drugs now generally used being sodium, potassium and ammonium bromide. before bromides were introduced by locock in 1857, very strict hygienic, dietic and personal disciplinary treatment combined with the use of drugs often effected improvement. since the use of bromides, these personal habits have, unfortunately, been neglected, far too much reliance being placed on the "three times a day after meals" formula. all bromides are quickly absorbed from the stomach and bowels, and enter the blood as sodium bromide, which lowers the activity of both motor and sensory centres, and renders the brain less sensitive to disturbing influences. unfortunately, the influence of bromides is variable, uncertain, and markedly good in only a small proportion of cases. in about 25 per cent of cases, in which mild seizures occur at long periods, without mental impairment, the bromides arrest the seizures, either temporarily or permanently, after a short course. in another 25 per cent the bromides lessen the frequency and severity of the fits, this being the common _temporary_ result of their use in _all cases_ in the first stages. in quite 50 per cent of cases, the effect of bromides diminishes as they are continued, and they finally exert no influence at all. many cases are temporarily "cured", the drug is stopped, and the seizures recur. bromides are valuable in recent and mild cases, but no medicine exerts much effect on severe cases of long standing, which usually end in an institution. when these drugs are taken continuously, nausea, vomiting, sleepiness, confusion of thought and speech, lapses of memory, palpitation, furred tongue, unsteady walk, acne and other symptoms of "bromism" may arise, whereupon the patient must stop taking bromides and see a doctor, who will substitute other drugs for a time. if heart palpitation be troublesome while using bromides, take a teaspoonful of sal volatile in water. see a doctor if you can; _until_ you see him, get from a chemist: potassii bromidi 10 grains. sodii bromidi 10 grains. boracis purificati 5 grains. aquæ 1 fluid ounce. two tablespoonfuls in water three times a day after meals. this prescription is for an adult. if the patient be under twenty-one, tell the chemist his age, and he will make it up proportionately. victims who have seizures with some regularity at a certain time, should take the three doses in one, two hours before the attack is expected. if there are long intervals between attacks, cease taking bromides after one fit and recommence three weeks before the next seizure is apprehended. when there is an interval of six months or more between attacks, take no drugs. bromides in solution are unpalatable, patients grow careless of regularity and dosage. you must learn from your doctor and your own experience the prescription, time and dose best suited to your case, and then _never miss a dose until you have been free from fits for two years_, for the beneficial action of bromide depends on the tissues becoming and remaining "saturated" with the drug. never give up bromides suddenly after long use, but gradually reduce the dose. it is just when the disease has been brought under control, that patients consider further doctor's bills an unnecessary expense, with the result that a little later the fits recur, and a tedious treatment has to be commenced over again. no value can be placed on any specific for epilepsy until it has been thoroughly tested for some years, and so proved that its effects are permanent, for almost any treatment is of value for a time, possibly through the agency of suggestion. * * * * * chapter xx patent medicines "men who prescribe purifications and spells and other illiberal practices of like kind."--hippocrates. "...corrupted by spell and medicines bought of mountebanks." "othello." act i. carlyle said the world consisted of "so many million people, _mostly fools_"; and he was right, for to public credulity alone is due the immense growth of the patent-medicine trade. it was formerly thought that for each disease, a specific drug could be found, but this idea is exploded. the doctor determines the exact condition of his patient, considers how he best may assist nature or prevent death, and selects suitable drugs. he carefully notes their action and modifies his treatment as required. the use of set prescriptions for set diseases is obsolete; the doctor of to-day treats the patient, not the disease. a few patent medicines are of limited value; many are made up from prescriptions culled from medical works, and the rest are frauds, like potato starch. the evil lies in charging from three to four hundred times a just price, in ascribing to a medicine which may be good for a certain disorder, a "cure-all" virtue it does not possess, and in inducing ignorant people to take powerful drugs, reckless of results. ephemeral patent-medicine businesses, run by charlatans, whose aim is frankly to make money before they are exposed, spring up like mushrooms; and their cunningly worded advertisements meet the eye in the columns of every paper one opens for a few months; then they drop out, to reappear under another name, at another address. these rogues buy a few gross pills from a wholesale druggist, insert a small advertisement, and so lay the foundations of a profitable business. the lure of the unknown is turned to account. "the discoverer went back to the heart of nature--and found many rare herbs used by native tribes." "the "heart of nature" was probably a single-room office tucked away down a fleet street alley, and analysis proves these medicines contain only common drugs, one "_herbal remedy_" being _metallic_ phosphates. a common procedure is to send a question form, and, after answering the query, "what are you suffering from?" with "neurasthenia", the company "carefully study" this, and then inform you with a gravity that would grace the pages of "punch", "you are the victim of a very intractable type of neurasthenia", so intractable in fact that it will need "additional treatment"--at an "additional" fee. the quack's advertisements are models of the skilful use of suggestion, and turn to rare account the half-knowledge of physiology most men pick up from periodicals. he frightens you with alarming and untrue statements, gains your confidence by a display of semi-true facts reinforced where weak by false assertions, and, having benefited himself far more than you, leaves you to do what you should have done at first, go to a doctor or a hospital. were it made compulsory for the recipe to be printed on all patent medicines, people would lose their childlike faith in coloured water and purges, and cease the foolish and dangerous practice of treating diseases of which they know little with drugs of which they know less. the british medical association of 429, strand, london, w.c., issue two 1_s_. books--"secret remedies: what they cost and what they contain", "more secret remedies"--giving the ingredients and cost price of most patent medicines. you are strongly urged to send for these books, which should be in every home. _the basis of every cure for epilepsy_ (not obviously fraudulent) _is bromides_. the usual method is to condemn vigorously the use of potassium bromide, and substitute ammonium or sodium bromide for it. some advertisers condemn all the bromides, and prescribe a mixture of them; others condemn potassium bromide, and shamelessly forward a pure solution of this same salt in water as a "positive cure!" in all cases the sale price is out of reasonable proportion to the cost, victims paying outrageous sums for very cheap drugs. most epileptics are poor, because their infirmity debars them from continuous or well-paid work, leaving them dependent on relatives, often in poor circumstances also. the picture of patients, already lacking many real necessities, still further denying themselves for weeks or months to purchase a worthless powder, is truly a pitiful one. bromides are unsatisfactory drugs in the treatment of epilepsy, but they are the best we have at present. get them made up to the prescription of a doctor, and see him every month to report progress and be examined. in the end, this plan will be very much cheaper, and incomparably better, than buying crude bromides from quacks. * * * * * there is no drug treatment for either hysteria or neurasthenia, and when the doctor gives medicines for these complaints, it is to remedy organic troubles, or, more often because necessity forces him to pander to the irrational and pernicious habit into which the public have fallen of expecting a bottle of medicine whenever they visit a doctor. osier, the famous professor of medicine at oxford, truly observed that he was the best doctor who knew the uselessness of medicines. but when public opinion demands a bottle, and is unwilling either to accept or pay for advice alone, the doctor may be forced to give medicines which he feels are of little value, hoping that their suggestive power will be greater than is their therapeutic value. neuropaths invariably contract the habit of physicking themselves, and taking patent foods and drugs which are valueless. so universal is this pernicious habit that we deem it desirable to criticize it here at some length. one highly popular type consists of port wine, reinforced (?) by malt and meat extracts, and sold under a fanciful name. it has about the same value as a bottle of port, which costs considerably less. it is well to remember that many a confirmed drunkard has commenced with these "restoratives". malt extracts are also popular. they contain diastase, and therefore aid the digestion of starch, but the diastatic power of most commercial extracts is negligible. meat extracts of various makes contain no nourishment, but are valuable appetisers. meat gravy is as effective and far cheaper. foods containing digestive ferments, which are widely advertised under various proprietary names are practically valueless, as are the ferments themselves sold commercially. digestive disorders are very rarely due to deficiency of ferments, while pepsin is the only one among all the ferments that could act (and that only for a little while) in the digestive system. some of the disadvantages of predigested foods have been noted, and their prices are usually so exorbitant that eggs at 2_s._ 6_d._ each would be cheaper. the remarks of sollmann the great pharmacologist are pertinent: _limitations_. the administration of food in the guise of medicine is sometimes advantageous; but medicinal foods are subject to the ordinary law of dietetics, and therefore cannot accomplish the wonders which are often claimed for them. the proprietary foods have been enormously overestimated, and have probably done more harm than good. the ultimate value of any food depends mainly on the amount of calories which it can yield, and on its supplying at least a minimum of proteins. in these respects, the medical foods are all inferior, for they cannot be administered practically in sufficient quantity to supply the needs of the body. they have a place as adjuvants to other foods, permitting the introduction of more food than the patient could otherwise be induced to take. aside from the special diabetes foods and cod-liver oil, their value is largely psychic. _predigested foods_. the value of these is doubtful, for digestive disturbances involve the motor functions and absorption more commonly than the chemical functions. their continued use often produces irritation. _liquid predigested foods_. as sold, these are flavoured solutions containing small amounts (½-6 per cent) of predigested proteins, ½-15 per cent of sugars and other carbohydrates, with 12-19 per cent of alcohol, and often with large quantities (up to 30 per cent) of glycerin. their protein content averages less than that of milk, and in energy value they are vastly inferior. their daily dose yields but 55-300 calories including their alcohol; this is only one-thirtieth to one-fifth the minimum requirements of resting patients. to increase their dose to that required to maintain nutrition would mean the ingestion of an amount of alcohol equivalent to a pint of whisky per day. of recent years very expensive preparations of real or alleged organic iron compounds have had a large sale. iron is a component of hæmoglobin, a solid constituent (13 per cent by weight) of the blood, which combines with the oxygen in the lungs, and is carried (as oxyhæmoglobin) all over the body, giving the oxygen up to the tissues. hæmoglobin is an exceedingly complex substance, but it contains only one-third per cent by weight of iron in organic form. the liver is the storehouse of iron, its reserve being depleted when there is an extraordinary demand for iron. the minute amounts of iron in ordinary food are amply sufficient for all our needs; any excess is simply stored, and, later excreted, and has no effect whatever on the circulating hæmoglobin. iron is only of value in certain forms of anæmia, and the many patent medicines purporting to contain hæmoglobin or organic iron are therefore useless to neuropaths. the roman plan of drinking water in which swords had been rusted, is quite as valuable as drinking expensive proprietary compounds. when iron is indicated blaud's pills are perhaps the best preparation. huge quantities of patent medicines containing phosphates in the form of hypo-or glycerophosphates, and (or) lecithin are sold annually. all phosphorus compounds are reduced to inorganic phosphates in the digestive tract, absorbed and eliminated, so that, as with iron, if phosphates are needed, the form in which they are taken is of no moment. why, then, pay huge sums for organic-phosphorus compounds (synthesized from inorganic phosphates) when they are immediately reduced to the same constituents from which they were constructed, the only value in the reduction process being seen in the immense fortunes which patent-medicine proprietors accumulate? lecithin is isolated from animal brain, or egg-yolk, and commercial lecithin is impure. not only does the ordinary daily diet contain ample lecithin (5 grammes), but two eggs will double this, while liver or sweetbread, both rich in phosphorous, may be eaten. the much-vaunted glycerophosphates are decomposed to and excreted as phosphates. sollmann's remarks apply to all similar proprietary articles: "a proprietary compound of glycerophosphates and casein has been widely and extravagantly advertised as 'sanatogen'. it is a very costly food, and in no sense superior to ordinary casein, such as cottage cheese." hypophosphites have been boomed by various people, chiefly for financial reasons. five or six of them are usually prescribed, with the addition of cod liver oil, and perhaps quinine, and (or) iron and strychnine, the complexity of the prescription being expected, apparently, to compensate for the uselessness of its various ingredients. to deduce rational remedies, it is first necessary to elucidate the causes of inefficiency; and to expect a brain which is out of order to function in an orderly manner simply because it is supplied with one of the substances necessary to its normal functioning (regardless of whether a deficiency of that substance is the cause of the disorder), is as rational as it would be to expect to restart an automobile engine, the magneto of which was broken, by filling up the half-empty petrol tank. * * * * * chapter xxi training the nervous child "when shall i begin to train my child?" said a young mother to an old doctor. "how old is the child, madam?" "two years, sir!" "then, madam, you have lost just two years," answered the old physician, gravely. neuropathic children are super-emotional, and from them come prodigies, geniuses, perverts and madmen. they are usually spare of build, with pale, sallow complexions, and dark rings under the eyes. they can never sit still, but wriggle restlessly about on their seats, pick their nostrils, and bite their nails. they are always wanting to be doing something, but soon tire of it, and start something else, which is as quickly cast aside; their energy is feverish but fitful. they jump to conclusions, quickly grasp ideas; as quickly forget them. having no capacity for calm, reasoned judgment, they are creatures of impulse, imperative but timid, suffer from strange ideas, and worry over trifles. the affections are strong and vehement, likes and dislikes are taken without reason, while intense personal attachments--often unrequited--occur, but not seldom swing round to indifference, or even bitter enmity. the passions and emotions are all abnormal, for owing to deficiency in the higher inhibitory centres, the victim is blown about by every idle emotional wind that blows. the slightest irritation may provoke an outburst of maniacal rage, or a fit. consequently, they require the most careful, but firm training, right from birth, to bring them up with a minimum of nerve-strain. twitchings, night or day terrors, sleep walking, and incontinence of urine often trouble them. they should be examined by a doctor once a year. these children have no _balance_, and are usually selfish, always garrulous, with a love of romancing, while a ready wit combined with fertile imagination often gains them a bubble reputation for learning they do not possess. invention, poetry, music, artistic taste and originality are occasionally of a high order, and the memory is sometimes phenomenal; but desultory, half-finished work, and shiftlessness are the rule. their appetite is fitful and fanciful, they like unsuitable foods, and their digestive system is easily upset. at puberty, sexual perversity is common, and the animal appetite, is as a rule, very strong, though rarely, it may be absent. during adolescence, there is excessive shyness or bravado, always introspection, and exaggerated self-consciousness. as they grow older, they readily contract hypochondria, neurasthenia, hysteria, alcoholism, insomnia and drug habits, and react unduly to the most trifling external causes, even to the weather, by which they are exhilarated or depressed. education. send them to school only when the law compels you, and observe them closely while there, for health is far more important to them than education. "infant prodigies" lack the mental staying power and physical robustness which real success demands, though they may do well for a time. go to your old school: the successes of to-day were dunces twenty years ago; about those whose names are proudly emblazoned in fading gold on rolls of honour, a discreet silence is maintained. keep a keen lookout for symptoms of over-effort. sleepiness, languor, a vacant expression, forehead wrinkled, eyebrows knit, eyes dull, sunken and surrounded by dark rings, twitchings, restlessness, or loss of appetite are all warnings that the pace is too strong for the child. "these are the cases in which the school board--who ordain that if children are well enough to play or run errands, they are well enough to attend school--should be defied." this defiance must of course be reinforced by a doctor's certificate. to the healthy, the strain of preparing for and enduring an examination is tremendous; to highly strung children it is dangerous. home-work should be forbidden in spite of the authorities. let the child join in the sports of the school as much as possible. school misdemeanours form a thorny problem, for discipline must be maintained, and a stern but just discipline is very wholesome for this type, who are too apt to assume that because they are abnormal, they can be idle and refractory. on the other hand, parents should promptly and vigorously object to their children being punished for errors in lessons, or struck on the head. diet. food, while being nourishing, and easily digested, must not be stimulating or "pappy". meat, condiments, tea, coffee and alcohol are highly undesirable, a child's beverage being milk and water. meals should be ready at regular hours, and capricious appetites should freely be humoured among suitable foods, served in appetizing form to tempt the palate. let them chatter, but see they do not get the time to talk by bolting their food. most children can chew properly soon after they are two, but they are never taught. their food is "mushy", or is carefully cut, and gives them no incentive to masticate. so long as food is digestible, the harder it is the better, and plain biscuits, raw fruits, and foods like "grape nuts", are splendid. mastication helps digestion; it also prevents nasal troubles. the desire for food at odd moments causes trouble, which is aggravated if the meals are not ready at stated hours. gently but firmly refuse the piece of bread-and-butter they crave, explain why you do so, and though they weep, or fly into a passion, do not lose your own temper, or beat, or give way to them. when accustomed to regular hours and firm refusals they will not crave for titbits between meals. it is very hard for them to see other members of the family freely partaking of condiments, drinks and unsuitable foods, and be told they are the only ones who must refrain. a little personal self-sacrifice helps immensely, and if your child _must_ refrain so _might_ you. all foods must be pure. avoid tinned goods, and cheap jams, which contain mangels and glucose. judged by the nutriment they contain--most cheap foods are very expensive. lightly boil, poach, or scramble eggs; steam fish and vegetables; cook rice and sago in the oven for three hours. see that milk puddings are chewed, for usually they are bolted more quickly than anything else. the stomach is expected to deal with unchewed rice pudding, because it is "nourishing". so are walnuts, but you do not swallow them whole. fruit must be fresh, ripe and raw, with skin and core removed. brown bread, crisply toasted and buttered when cold, is best. porridge is admirable, but many children dislike it. try to induce a taste by giving plenty of milk, and sugar or syrup with it. the starch-digesting ferments in the saliva and pancreas are not active until the age of 18 months, before which infants must not be given starchy foods like potatoes, cereals, puddings and bread. all greenstuffs must be thoroughly washed, or worms may pass into the system. foul breath, picking the nose, restlessness, fever and startings are often attributed to worms, when the real "worms" are mince pies, raisins, sour apples, and even beer. never force fat on children in a form they do not like, for there are plenty of palatable fats, as butter, dripping, lard and milk. cream is as cheap, as good, and far nicer than cod-liver oil. decide on your children's diet, but do not discuss it with or before them. if a child _does_ dislike a dish, never force it on him, but try to induce a liking by serving it in a more appetizing way. never mix medicines with food. worms. various symptoms are due to intestinal worms, and a sharp lookout should be kept for the appearance of any in the stools, and suitable treatment given when necessary. treatment for thread and round worms: r. santonini........................gr. ij. hydrarg. chloridi mitis..........gr. ij. pulv. aromatici..................gr. iv. mix and divide into four. take one at bedtime every other night, followed by castor oil in the morning. tapeworms. these are rarer, being much more frequently talked or read about than seen. a doctor should be consulted. moral training. the road to hell is broad and easy; so is that to heaven, for if bad habits are easily acquired, so are good ones. example is the best moral precept, and if the conduct of parents is good, little moral exhortation is needed. "what is the moral ideal set before children in most families? not to be noisy, not to put the fingers in the nose or mouth, not to help themselves with their hands at table, not to walk in puddles when it rains, etc. to be 'good'!" to hedge in the child's little world, the most wonderful it will ever know, by hidebound rules enforced by severe punishments, is to repress a child, not to train it. while the commonest error is to spoil a child, it is just as harmful to crush it. be firm, be kindly, and, above all, _be fair_. issue no command hastily, but only if necessary, and shun prohibitions based on petulance or pique. give the child what it wants if easily obtainable and not harmful. if the desire is harmful, explain why, but if a child asks for a toy, do not pettishly reply: "it's nearly bedtime!" when it is not, or even if it is. discipline is essential, but discipline does not consist in inconsistent nagging; harshly insisting on unquestioning obedience to some unreasonable command one moment, and weakly giving way--to avoid a scene--on some matter vitally affecting the child's welfare the next. there must be no coddling, and no inducement to self-pity. such children must be taught that they are capable of real success and real failure, and that upon personal obedience to the laws of health of body and of mind, this success or failure largely depends. a child should be early accustomed to have confidence in himself. for this purpose all about him must encourage him and receive with kindliness whatever he does or says out of goodwill, only giving him gently to understand, if necessary, that he might have done better and been more successful if he had followed this or that other course. nothing is more apt to deprive a child of confidence in himself than to tell him brutally that he does not understand, does not know how, cannot do this or that, or to laugh at his attempts. his educators must persuade him that he _can_ understand, and that he _can_ do this thing or that, and must be pleased with his slightest effort. it seems a trifle to let a child have the run of cake plate or sweet-tray, or to stay up "just another five minutes, mummy!" to avoid a howl, but these are the trifles that sow acts to reap habits, habits to reap character, and character to fulfil destiny. it is selfish of parents to avoid trouble by not teaching their children habits of obedience, self-restraint, order and unselfishness. between five and ten is the age of greatest imitation, when habits are most readily contracted. come to no decision until hearing the child's wishes or statements, and thinking the matter out; having come to it, _be inexorable_ despite the wiles, whines and wails of a subtle child. reduce both promises and threats to a minimum, but _rigidly_ fulfil them, for a threat which can be ignored, and a promise unfulfilled, are awful errors in training a child. persuade, rather than prohibit or prevent, a child from doing harmful actions. if it wants to touch a hot iron, say clearly it is hot, and will burn, but _do not move it_. then, if the child persists, it will touch the iron tentatively, and the small discomfort will teach it that obedience would have been better. let it learn as far as possible by the hard, but wholesome, road of experience. makeshift answers must never be given to a child. awkward questions require truthful answers, even though these only suggest more "whys?" sentimentality must be nipped promptly in the bud, and an imaginative and humorous view of things encouraged. the child must be taught to keep the passions under control, and to face pain (that great educator which neurotic natures feel with exaggerated keenness) with fortitude. fear must be excluded from a child's experience. "bogies!" "ghosts!" "robbers!" and "black-men!" if unintroduced, will not naturally be feared. the mental harm a highly strung child does by rearing most fearsome imaginings on small foundations is incalculable, and has led more than one to an asylum. try to train the child to go to sleep in the dark, but if it is frightened give it a nightlight. as guthrie says, the comfort derived from the assurance that unseen powers are watching over it, is small compared to that given by a nightlight. he mentions a child who, when told she need not fear the dark because god would be with her, said: "i wish you'd take god away and leave the candle." if the child wakes terrified, it is stupid and wicked to call upstairs: "go to sleep!" a child cannot go to sleep in that state, and a wise mother will go up and softly soothe the frightened eyes to sleep. neuropathic children often have night terrors within an hour or two of going to bed. piercing screams cause a hasty rush upstairs, where the child is found sitting up in bed, crouching in a corner, or trying to get out of door or window. his face is distorted with fear and he stares wildly at the part of the room in which he sees the terrifying apparition. he clings to his mother but does not know her. after some time he recovers, but is in a pitiful state and has to have his hand held while he dozes fitfully off. he often wets the bed or passes a large amount of colourless urine. medical treatment is imperative. corporal punishment is unsuitable for neuropathic children, for the mere suggestion of its application usually causes such excessive dread, mental upset and terror as make it really dangerous. such children are often said to be "naughty" when in reality they are unable to exercise self-control, owing to defective inhibitory power. try patiently to inculcate obedience from the desire to do right, and make chastisement efficacious from its very exceptional character. "the young child is too unconscious to have a deliberately perverse intention; to ascribe to him the fixed determination to do evil, is to judge him unjustly and often to develop in him an evil instinct. it is better in such a case to tell him he has made a mistake, that he did not foresee the consequences to which his action might lead, etc." many parents fall into a habit of shaking, ear-boxing, and such-like harmful minor punishments for equally minor offences, which should be overlooked. in all little troubles, keep _quite calm_. the child's nerve and association centres have not yet got "hooked up", and you cannot expect it to act reasonably instead of impulsively. this excuse does not apply to you. one excitable person is more than enough, for if both get angry, sensible measures will certainly not result. the necessity for calmness cannot too strongly be urged. the treatment for a fit of temper, is to give the unfortunate child a warm bath, and put it to bed, with a few toys, when it will soon fall asleep, and awake refreshed and calm. proceed gently but with absolute firmness, _start early_, and remember that example is better than precept. religion. offering advice on this subject is skating on very thin ice, and we do so but to give grave warning against neuropathic youth being allowed to contract religious "mania", "ecstasy", or "exaltation". neuropaths are given naturally to "see visions and dream dreams", and if this tendency be exaggerated an unbalanced moral type results. jones says: "the epileptic is apt to be greatly influenced by the mystical or awe-inspiring, and is disposed to morbid piety. he has an outer religiousness without corresponding strictness of morals; indeed the sentiment of religious exaltation may be in great contrast to his habitual conduct, which is a mixture of irritability, vice and perverted instincts." lay stress on the simple moral teaching of the new testament, and avoid cranky creeds, cross references, or higher criticism. teach them to practise the moral precepts, not to quote them by the page. without this practical bent, a "revival" meeting is apt to result in a transient but harmful "conversion"; a form of religious sentiment which finds outlet, not so much in works as in morbid excitement. in these people, as in the insane, there is often a weird mixing-up of religious and sexual emotion. teach these children that the greatest good is not to sob over their fancied sins at "salvation" meetings, but to love the just and good, to hate the unjust and evil, and to do unto others as they would others should do unto them. it is better for them to join one of the great churches, than become members of those small sects which maintain peculiar tenets. a word of special warning must be given against spiritualism. there may or may not be a foundation for this belief, but it is highly abnormal, and has led thousands into asylums. the medium and the majority of her audience are highly neurotic, and a more unwholesome environment for an actual or potential neuropath could not be imagined. the educated neuropath often peruses certain agnostic works, the result usually being deplorable, for this class are dependent on some stable base outside themselves, such as is found in a calm religion manifested in a steadfast attempt to overcome the weakness of the flesh, by ordering life in accordance with the teachings of the new testament. so long as abnormalities of character do not become too pronounced, friends must be content. such children must be trained to express themselves in a practical manner, not in weaving gorgeous phantasies in which they march to imaginary victory. day dreams form one of those unlatched doors of the madhouse that swing open at a touch, the phantasy of to-day being written "emotional dementia" on a lunacy certificate to-morrow. finally, remember that above them hangs the curse: "unstable as water, _thou shall not excel_." "go thou softly with them, all their days!" and whether your tears fall on the ashes of a loved and loving, but weak and wilful one, or whether their tears bedew the grave of the only friend they ever knew, you will not have lacked a rich reward. * * * * * chapter xxii dangers at and after puberty "th' expense of spirit in a waste of shame is lust in action;

_learn he will_; if you will not teach your child, his pet rabbit will. when children ask awkward questions, say quietly that such matters are not discussed with children, but promise to tell them all about it when they are ten years old; delay no longer, for most children learn self-abuse between ten and twelve. self-abuse is a bad habit, and no more a "sin" than is biting the nails. unfortunately, people with no other qualification than a desire to do good, wrongly harp on the "sin" of it and draw lurid pictures of physical and mental wreck as the end of such "sinners", ignorant that if all masturbators went mad the world would be one huge asylum. exaggeration never pays in teaching youth. tell the truth, which is bad enough without adding "white lies" with an eye to effect. coitus causes slight prostration, nature's device to remind man to keep sexual intercourse within bounds, for while in moderation it is harmless, in excess it causes great prostration. _exactly the same applies to self-abuse_, for, paradoxical as it seems, the real harm is done by the _fear_ of the supposed harm. the masturbator first suffers from the knowledge he is indulging in a pleasure he knows would be forbidden, and from fear of being found out; later he learns from friends, quack advertisements, or well-meaning books that self-abuse is a most deadly practice, and thereupon a tremendous struggle occurs between desire and fear, each act ending in an agony of remorse and dread of future consequences, which struggle does a thousand-fold more harm than the loss of a little semen. the ill-effects of these mental struggles disappear after marriage, which means greater indulgence, but indulgence free from mental stress. in neuropaths, these mental struggles are the worst things that could occur, for they tend to make permanent the states we are trying to cure. the most serious results of masturbation are moral not physical. loss of will-power, self-reliance, presence of mind, reasoning power, memory, courage, idealism, and self-control; mental and physical debility, laziness, a diseased fondness for the opposite sex, and in later years, some degree of impotence or sterility, are its commoner results. teach _your_ child, therefore, not from fear of physical harm, but because you wish him to be one of those fortunate few who live and die "gentlemen unafraid", because they had wise parents. let the mother instruct a girl, the father a boy, and not leave so vital a matter to an unsuitable pamphlet. buy one of the many "knowledge for boys or girls" books and read it carefully. having made sure you can convey a simple account of the wonders of reproduction, and that you have rooted out the idea that sex is something to be apologized for, see the child and tell him it is time he learned of his private parts, as manhood draws near. then, speaking in a quiet, unembarrassed way, deliver your little homily, all the time insisting on the marvel, the romance, the poetry and the beauty of the sex. let chivalry be your text, not fear, and repeat the squire's sound parting advice to tom brown: "never listen to or say things you would not have your mother or sister hear." give a clear and complete description in simple words of the mechanism and marvel of reproduction, for half-knowledge generates a prurient curiosity about the other sex, thus defeating the very end you have so earnestly striven for. purity not impurity should be your text, and you should only refer to masturbation as a harmful habit, which should not be contracted. warn them to "keep the heart with all diligence, for out of it are the issues of life!" by turning their thoughts instantly and determinedly away from sex ideas when they arise, as they _will_ arise, time and again. it is useless to try _not_ to think of them, the child must instantly turn its thoughts to to _something else_, for one who cannot stamp out a spark will not subdue a fiercely-raging conflagration. babies should not be carelessly caressed, and a fretful infant must never be soothed by playing with the genitals, as is done innocently by some mothers and nurses, and by others from motives more questionable. freud showed that there are subconscious sexual desires in infants, which die out until reanimated at puberty in nature's own way. if exaggerated by exuberant fondling, they gather force in the dark corners of the mind, and are later manifested in morbid sexual or mental perversity. if you have good grounds for believing the habit has already been contracted, enlist medical advice. a great factor in the successful treatment of self-abuse is early recognition, and, after the unhygienic nature of the habit has carefully been pointed out, the child's sense of honour should be invoked. without further reference to the matter, try to become your child's confidant, for he will have to fight fires within and foes without. see that his time is filled with healthy sport and play, and ennoble his ideas with talk, books and plays which lay stress on chivalry and manliness. give him plain food, tepid douches, and a firm bed with light, fairly warm clothing. get him up reasonably early in the morning, and let him play until he is "dog-tired" at night. let children rub shoulders with others, keep them from highly exciting tales, let them read but little, and train them to be observant of external objects all the time. neuropaths develop very early sexually, and contract bad habits in the endeavour to still their unruly passions; with them, the future is darker than with the normal child, and the parent who neglects his duty may justly be held accountable for what happens to his child or his child's children. puberty is always a critical period in epilepsy, many cases commencing at this time, while in a number, fits commence in infancy, cease during childhood, and recommence at puberty, the baneful stimulus of masturbation being undoubtedly a factor in many of these cases. * * * * * chapter xxiii work and play although most people would assume that epileptics are unable to follow a trade, there is hardly an occupation from medicine to mining, from agriculture to acting, that does not include epileptics among its votaries. outdoor occupations involving but little mental work or responsibility are best, but unfortunately just those which promise excitement and change are those which appeal to the neuropath. a light, clean, manual trade should be chosen, and those that mean work in stuffy factories, amid whirring wheels and harmful fumes, using dangerous tools, or climbing ladders, must be avoided. for the fairly robust, gardening or farming are good occupations, such workers getting pure air, continuous exercise, and little brain-work. wood-working trades are good, if dangerous tools like circular saws are left to others. for the frail neuropath with a fair education, drawing, modelling, book-keeping, and similar semi-sedentary work may do. other patients might be suited as shoemakers, stonemasons, painters, plumbers or domestic servants, so long as they always work on the ground. some work is essential; better an unsuitable occupation than none at all, for the downward tendency of the complaint is sufficiently marked without the victim becoming an idler. work gives stability. epilepsy limits patients to a humble sphere, and though this is hard to a man of talent, it is but one of many hard lessons, the hardest being to realize clearly his own limitations. if seizures be frequent, the ignorant often refuse to work with a victim, who can only procure odd jobs, in which case he should strive to find home-work, at which he can work slowly and go to bed when he feels ill. a card in the window, a few handbills distributed in the district, judicious canvassing, and perhaps the patronage of the local doctor and clergy may procure enough work to pay expenses and leave a little over, for the essential thing is to occupy the mind and exercise the body, not to make money. very few trades can be plied at home and many swindlers obtain money under the pretence of finding such employment, charging an excessive price for an "outfit", and then refusing to buy the output, usually on the pretext that it is inferior. envelope-addressing, postcard-painting and machine-knitting have all been abused to this end. an auto-knitter seems to offer possibilities, but victims must investigate offers carefully. photography is easy. a cheap outfit will make excellent postcards, modern methods having got rid of the dark room and much of the mess, and postcard-size prints can be pasted on various attractive mounts. if the work is done slowly, and in a good light, and the patient has an aptitude for it, ticket-writing is pleasant. among small shopkeepers there is a constant demand for good, plainly printed tickets at a reasonable price. on an allotment near home vegetables and poultry might be raised, an important contribution to the household, and one which removes the stigma of being a non-earner. the mental discipline furnished by this home-work is invaluable, neuropaths, especially if untrained, are unable to concentrate their attention on any matter for long, and do their work hastily to get it finished. when they find that to sell the work it must be done slowly and perfectly they have made a great advance towards training their minds to concentrate. their weak inhibitory power is thus strengthened with happy results all round. when the work and the weather permit, work should be done outdoors, and when done indoors windows should be opened, and, if possible, an empty or sparsely-furnished bedroom chosen for the work. recreations. these offer a freer choice, but those causing fatigue or excitement must be avoided, for patients who have no energy to waste need only fresh air and quiet exercise. manual are better than mental relaxations. dancing is unsuitable, swimming dangerous, athletics too tiring and exciting. bowls, croquet, golf, walking, quoits, billiards, parlour games and quiet gymnastics without apparatus are good, if played in moderation and much more gently than normal people play them. play is recreation only so long as a pastime is not turned into a business. when a player is annoyed at losing, though he loses naught save his own temper, any game has ceased to be recreative. * * * * * chapter xxiv heredity "man is composed of characters derived from pre-existing germ-cells, over which he has no control. be they good, bad, or indifferent, these factors are his from his ancestry; the possession of them is to him a matter of neither blame nor praise, but of necessity. they are inevitable."--leighton. the body is composed of myriads of cells of _protoplasm_, in each of which, is a _nucleus_ which contains the factors of the hereditary nature of the cell. in growth, the nucleus splits in half, a wall grows between and each new cell has half the original factors, female _ovum_ and male _sperm_ (the cells concerned with reproduction) divide, thus losing half their factors, and when brought together by sexual intercourse form a _germ-cell_ having an equal number of factors from mother and father. how these factors are mingled--whether shuffled like two packs of cards, or mixed like two paints--we do not know. if two opposite factors are brought together, one must lie dormant. the offspring may be male or female, tall or short; it cannot be both, nor will there be a mixture. _this rule only applies to clearly defined factors._ we are _made by_ the _germ-plasm_ handed down to us by our ancestors; in turn we pass it on to our children, _unaltered_, but mixed with our partner's plasm. "the dead dominate the living" for our physical and mental inheritance is a mosaic made by our ancestors. variations which may or may not be inheritable do arise spontaneously, we know not how, and by variations all living things evolve. a child resembles his parents more than strangers, not because they made cells "after their own image" but because both he and they got their factors from the same source. man's physical and mental, and the _basis_ of his moral, qualities depend entirely on the types of ancestral plasm combined in marriage. man may control his environment; his heritage is immutable. to suppress an undesirable trait the germ-cell must unite with one that has never shown it--one from a sound stock. an unsuitable mating in a later generation, however, may bring it out again (for factors are indestructible), and the individual showing it will have "reverted to ancestral type". to give an instance: does the son of a drunkard inherit a tendency to drink? no! the father is alcoholic because he lacks control, consequent upon the factors which make for control having been absent from his germ-plasm. he passes on this lack; if the mother does the same, the defect occurs--in a worse form--in the son. if the mother gives a control factor, the son may be unstable or _apparently_ stable, this depending entirely on chance, but if the mother's plasm contains a _strong_ control-factor, the defect will lie dormant in her son, who will have self-control, though if he marries the wrong woman he will have weak-willed children. if the son becomes a toper, therefore, it is because he, like his father before him, was born with a defect--weak control--which might have made of him a drug-fiend, a tobacco-slave, a rake, or a criminal; in his home drink would naturally be the temptation nearest to hand, and he would show his lack of control in drunkenness. the way a lily-seed is treated makes a vast difference to the plant which arises. if sown in poor soil, and neglected, a dwarf, sickly plant will result; if sown in rich soil, and given every care that enthusiasm, money and skill can suggest or procure, the result will be magnificent. so with man. a well-nourished mother, free from care and disease, may have a finer child than a half-starved woman, crushed by worry and work, but neither starvation nor nourishment alter the inborn character of the child. the _body-cells_ are greatly changed by disease, poison, injury, and overwork, but these changes are not passed on, and despite the influence of disease from time immemorial, the _germ-cell_ produces the same man as in ancient days. without this fixity of character, this "continuity of the germ-plasm", "man" would cease to be, for the descendants of changeable cells would be of infinite variety, having fixity of neither form nor character. epilepsy, hysteria and neurasthenia are all outward signs of defect in the germ-plasm, and so they (or a predisposition to them) can be passed on, and inherited. if a man shows a certain character, his plasm, had, and has, the causative factor. he may have received it from _both_ his parents, when it will be _strong_, or from one only, when it will be _normal_. if he have it not, it is absent. the same applies to the plasm of the woman he mates, so there are six possible combinations, with results according to "mendel's law." _all_ the children will not inherit a taint unless _both_ parents possess it, but, however strong one parent be, if the other is tainted, _none_ of the children can be absolutely clean, but will show the taint, weak, strong, or dormant. this means that neuropathy will recur--and that it has previously occurred--in the same family, unless there be continual mating into sound stocks. if there is continual mating into bad stocks, it will recur frequently and in severe forms. all intermediate stages may occur, depending entirely on the qualities of the combining stocks. from this we shall expect, in the same stock, signs of neuropathic taint other than the three diseases dealt with here, and these we get; for alcoholism, criminality, chorea, deformities, insanity and other brain diseases, are not infrequent among the relatives of a neuropath, showing that the family germ-plasm is unsound. epilepsy, one symptom of taint, is more or less interchangeable with other defects; the taint, as a whole, is an inheritable unit whose inheritance will appear as any one of many defects. this is shown by the fact that very few epileptics have an epileptic parent. starr's analysis of 700 cases of epilepsy emphasizes this point. epilepsy in a parent 6 epilepsy in a near relative 136 alcoholism in a parent 120 nervous diseases in family 118 rheumatism and tuberculosis 184 combinations of above diseases 142 as medicine and surgery cannot add or delete plasmic factors, the only way to stamp out neuropathy in severe forms would be to sterilize victims by x-rays. this would be painless, would protect the race and not interfere with personal or even with sexual liberty. in fifty years such diseases would be almost extinct, and those arising from accident or the chance union of dormant factors in apparently normal people could easily be dealt with. there are 100,000 epileptics in great britain, and as _all_ their children carry a taint which tends to reappear as epilepsy in a later generation _the number of epileptics doubles every forty years_. we protect these unfortunates against others; why not posterity against them? neuropaths must pass on _some_ defect; therefore, though victims may marry, _no neuropath has a right to have children_. * * * * * chapter xxv character "all men are not equal, either at birth or by training. nature gives each of us the neural clay, with its properties of pliability and of receiving impressions; nurture moulds and fashions it, until a _character_ is formed, a mingling of innate disposition and acquired powers. but clay will be clay to the end; you cannot expect it to be marble."--thomson & geddes. "heaven lay not my transgression to my charge."--king john. it is essential that attendants, relatives, and friends carefully study the character of neuropaths, and recognize clearly how abnormal it is, for untold misery is caused by judging neuropaths by normal standards. patients are often harshly treated because others regard the victim of defective inhibition as having gone deliberately to work, through wicked perversity and pure wilfulness, to make himself a nuisance, to persist in being a nuisance, and to refuse to be other than a nuisance, rather than exercise what more fortunate men are pleased to term self-control. character is usually appraised as "good" or "evil" by the nature of a man's actions, the assumption being made that he can control his impulses if he be so minded. this is not so. "good" and "evil" are only relative terms. what one man thinks "evil", a second holds "good", while a third is not influenced. now the performance of the act judged is directed by the performer's brain, the constitution of which was pre-determined by the germ-plasm from which he arose, so that _the basis of character is inherited_. the moral sense is the last evolved and least stable attribute of the last evolved and least stable of our organs, the brain; and brains are born, not made to order. to blame a man for having weak control--a sick will--is as unreasonable as to blame him for a cleft palate or a squint. the "good" people who jog so quietly through life little reck how much they owe their ancestors, from whom they received stability. these tendencies represent the total material for building character. training and environment can only nourish good tendencies and give bad ones no encouragement to grow gigantic. if training and environment alone formed character, then children reared together would be of similar disposition; by no means the case. similarly, if external influences altered inborn tendencies, then, not only would the evil man be totally reformed by strong inducements to virtue, but strong inducements to vice would lead totally astray the good man, for "good" is no _stronger_ than "evil", both being attributes of mind. in mind as in body, from the moment he is conceived to the moment his dust rests in the tomb, man is directed by immutable laws, though he is not simply a machine directed by impulses over which he has no control. there is real meaning in "strong will" and "weak will" will being a tendency to deliberate before and be steadfast in action, a tendency which varies immensely in different people. the fallacy of "free will" lies in assuming that every one has this tendency equally developed, making character a mere matter of saying "yes!" and "no!" without reference to the individual's mental make-up. deliberate, persistent wickedness implies a strong will, just what neuropaths lack. a man of weak will can never be a very good nor yet a very bad man. he will be very good at times, very bad at times, and neutral at times, but neither for long; before sudden impulses, whether good or bad, neuropaths are largely powerless. the many perversities of a neuropath are not deliberately put forth of his "free will" to annoy both himself and others, for the neuropath inherits his weak-control no less than his large hands. friends _must_ remember they are dealing with a person whose _nature_ it is to "go off half-cock", and who cannot be normal "if he likes". the neuropath, young or old, says what he "thinks" _without thinking_, that is he says what he _feels_, and acts hastily without weighing consequences. _cassius_: have you not love enough to bear with me, when that rash humour which my mother gave me makes me forgetful? _brutus_: yes, cassius; and, from henceforth when you are over-earnest with your brutus, he'll think your mother chides, and leave you so. * * * * * one cannot detail the effects of neuropathy on character, when its victims include madmen, sexual perverts, idiots, criminals, imbeciles, prostitutes, humble but honest citizens, common nuisances, invalids of many kinds, misanthropists, designers, enthusiasts, composers, communists, reformers, authors, artists, agitators, statesmen, poets, prophets, priests and kings. very mild epilepsy--from one fit a year to one in several years--instead of hindering, seems rather to help mentality, and many geniuses have been epileptic. these talented victims, are less rare than the public suppose, owing to the jealous care with which symptoms of this disease are guarded. socrates, julius cæsar, mahomet, joan of arc, peter the great, napoleon, byron, swinburne, and dostoieffsky are but a few among many great names in the world of art, religion and statecraft. epileptic princes, kings and kinglets who have achieved unenviable notoriety might be named by scores, wilhelm ii being the most notable of modern times. this brilliant mentality is always accompanied by instability, and usually by marked disability in other ways. the success of these men often depends on an ability to view things from a new, quaint or queer standpoint, which appeals to their more normal fellows. in matters that require great fertility, a quick grasp, ready wit, and brilliant but not sustained mental effort, numerous neuropaths excel. in things calling for calm, well-balanced judgment, or stern effort to conquer unforseen difficulties, they fail utterly. subtle in debate, they are but stumbling-blocks in council; brilliant in conception, they fail in execution; fanciful designers, they are not "builders of bridges". they are boastful, sparkling, inventive, witty, garrulous, vain and supersensitive, outraging their friends by the extravagance of their schemes; embarrassing their enemies by the subtlety of their intrigues. they wing on exuberant imagination from height to height, but the small boulders of difficulty trip them up, for they are hopelessly unpractical; they have neither strength of purpose nor fortitude, and their best-laid schemes are always frustrated at the critical moment, by either the incurable blight of vacillation, or by the determination to amplify their scheme ere it has proved successful, sacrificing probable results for visionary improvements. great and cunning strategists while fortune smiles, they are impotent to direct a retreat, but flee before the fury they ought to face. they rarely have personal courage, but are timid, conciliatory and vacillating just when bravery, sternness, and determination are needed; furious, obstinate and reckless, when gentleness, diplomacy and wisdom would carry their point. they are ready to forgive when there is magnanimity, vainglory and probably folly in forgiveness, but will not overlook the most trivial affront when there is every reason for so doing. they have brain, but not ballast, and their whole life is usually a lopsided effort to "play to the gallery". in poetry and literature, fancy has free play, and they often succeed, sometimes rising to sublime heights; usually in the depiction of the whimsical, the wonderful, the sardonic, the bizarre, the monstrous, or the frankly impossible. they are not architects as much as jugglers of words, and descriptive writing from an acute angle of vision is their forte. they sometimes succeed as artists or composers, for in these spheres they need not elaborate their ideas in such clean-cut detail, but many who might succeed in these branches have not sufficient strength of purpose to do the preliminary "spadework". they have too many talents, too many differing inclinations, too much impetuosity, too much vanity, too little concentration and will-power, and they fail in ordinary walks of life from the lack of resolution to lay the foundations necessary to successful mediocrity. no greater obstacle to progress exists than the reputation for talent which this class acquire on a flimsy basis of superficial brilliance in conversation or a penchant for witty repartee. they are self-opinionated and egoistical, with a conceit and assurance out of all proportion to their abilities. their mental perspective is distorted and they are conspicuous for their obstinacy. in conversation they are prolix and pretentious, and they often contract religious mania, in which their actions by no means accord with their protestations, for they have very elementary notions of right and wrong, or no notions at all. often they are precocious, but untruthful, cruel, and vicious; the despair of relatives, friends, and teachers. they combine unusual frankness with an audacity and impulsiveness that is very misleading, for below this show of fire and power there is no stability. their character is a tangle of mercurial moods, the neuropath being passionate but loving, sullen one moment, overflowing with sentimental affection the next, vicious a little while later, quick to unreasoning anger, and as quick to repent or forgive, obstinate but easily led, versatile but inconstant, noble and mean by turns, full of contradictions and contrasts, at best a brilliant failure, vain, deaf to advice or reproof, having in his ailing frame the virtues and vices of a dozen normal men. mercier aptly describes him: "there is a large class of persons who are often of acute and nimble intelligence, in general ability equal to or above the average, of an active, bustling disposition, but who are utterly devoid of industry. for by industry we mean steady persistence in a continuous employment in spite of monotony and distastefulness; an employment that is followed at the cost of present gratification for the sake of future benefit. of such self-sacrifice these persons are incapable. they are always busy, but their activity is recreative, in the sense that it is congenial to them, and from it they derive immediate gratification. as soon as they tire of what they are doing, as soon as their occupation ceases to be in itself attractive it is relinquished for something else, which in its turn is abandoned as soon as it becomes tedious. "such people form a well-characterized class: they are clever; they readily acquire accomplishments which do not need great application; and agreeably to the recreative character of their occupations, their natures are well developed on the artistic side. they draw, paint, sing, play, write verses and make various pretty things with easy dexterity. their lack of industry prevents them ever mastering the technique of any art; they have artistic tastes, but are always amateurs. "with the vice of busy idleness they display other vices. the same inability to forgo immediate enjoyment, at whatever cost, shows itself in other acts. they are nearly always spendthrifts, usually drunkards, often sexually dissolute. next to their lack of industry, their most conspicuous quality is their incurable mendacity. their readiness, their resources, their promptitude, the elaborate circumstantiality of their lies are astonishing. the copiousness and efficiency of their excuses for failing to do what they have undertaken would convince anyone who had no experience of their capabilities in this way. "withal, they are excellent company, pleasant companions, good-natured, easy-going, and urbane. their self-conceit is inordinate, and remains undiminished in spite of repeated failures in the most important affairs of life. they see themselves fall immeasurably behind those who are admittedly their inferiors in cleverness, yet they are not only cheery and content, but their confidence in their own powers and general superiority to other people remains undiminished. "_the lack of self-restraint is plainly an inborn character_, for it may show itself in but one member of the family brought up in exactly the same circumstances as other members who do not show any such peculiarity. the victim is born with one important mental faculty defective, precisely as another may be born with hare-lip." in neuropaths the mental mechanism of _projection_, which we all show, is often marked. any personal shortcoming, being repugnant to us causes self-reproach, which we avoid by "projecting" the fault (unconsciously) on some one else. readers should get "the idiot" by fedor dostoieffsky, an epileptic genius who saw that for those like him, happiness could be got through peace of mind alone, and not in the cut-throat struggle for worldly success. he projected his stabler self into prince muishkin, the idiot, and every one of the six hundred odd pages of this amazing description of a neuropathic nation is stamped with the hall-mark of genius. * * * * * chapter xxvi marriage "between two beings so complex and so diverse as man and woman, the whole of life is not too long for them to know one another well, and to learn to love one another worthily."--comte. no neuropath should have children, but marriage is good in mild cases, for neuropaths are benefited by sympathetic companionship, and their sexual passions are so strong that they must be gratified, by marriage, prostitution, or unnaturally. bernard shaw's sneer- "marriage is popular because it combines the maximum of temptation with the maximum of opportunity"-is justifiable, though the "maximum of opportunity" is better than a maximum of unnatural devices to satisfy and intensify normal and abnormal cravings. there is a popular belief that an epileptic girl is cured by pregnancy, a state that ought never to occur. the lack of sex-education causes millions of miserable marriages. sexual desire is cultivated out of all proportion to other desires, the will cannot control the desire to relieve an intolerable sense of discomfort, and men eagerly seize the first chance of being able to satisfy these fierce cravings at pleasure. if sex were treated sensibly it would develop into a powerful instead of an overpowering appetite, and reason would have some say in the choice of a life-partner. a neuropath needs a calm, even-tempered, "motherly" wife. for him, gentleness, self-control, sound common sense and domestic virtues are superior to wit or beauty. unfortunately, contrary to public belief, people are attracted by their like, not by their opposites. the sensitive, refined neuropath finds the normal person insipid and dull; the normal person is rendered uncomfortable by the morbid caprices of the neuropath. there must be no disparity of age, for at the menopause the woman no longer seeks the sexual embrace, and if her husband be young unfaithfulness ensues. not only that, but she, knowing, probably to her sorrow, how rarely the hopes of youth mature, cannot take a keen interest in his ambitions like a younger woman, or fire his dying enthusiasm at difficult parts of the way. if he be his wife's senior he will be as little able to appreciate her ideas and habits. an excitable, volatile, garrulous, "neighbourly" woman, or one who can do little save strum on the piano or make embroidery as intricate as it is useless, means divorce or murder. for him, sweetness, gentleness, self-control, sound common sense, shrewdness, and domestic virtues are incomparably superior to any mental brilliance or physical comeliness. he needs a "homely" woman, and should remember that no banking account can match a sweet, womanly personality, and no charms compare to a sunny heart, and an ability steadfastly to "see the silver lining". he must on no account marry a woman in indifferent health, for under the strain of her husband's infirmity the woman, who if she were well would be a help, is a source of expense, worry and friction. on the other hand the woman who receives a proposal from a neuropath, be he ever so gifted, has grave grounds for pausing, though it is hard to counter the specious arguments of one who may be "a man o' pairts", a witty companion and an ardent lover. it is doubtful if a neuropath is ever permeated by a steadfast emotion, for all his emotions are fierce but unstable, the love of an inconsistent man being ten times more ardent than that of a faithful one, _while it lasts_. "you can't marry a man without taking his faults with his virtues," and love must be strong enough to stand, not storms alone, but the minor miseries of life, the incessant pinpricks, the dreary days when the smile abroad has become the scowl at home. at best, her husband will be capricious, hard to please, and though rabidly jealous without cause, at the same time very partial to the attractions of other women. he usually needs the attention of the whole household, which his varying health and moods keep in a mingled state of anxious solicitude and smouldering resentment. his infirmity may mean a very secluded and humdrum life. she will have to make home an ever-cheery place, an ideal that means hard work and self-sacrifice through lonesome years in which her nobility will be unrecognized and unrewarded. a woman fond of amusements and sport, and having many acquaintances would find this unbearable. any happiness in marriage to a neuropath is largely dependent on the self-sacrifice of the wife. should marriage occur, the wife must judiciously curb her husband's passions without driving him to other women by coldness, a problem which is often solved by separation. the suggestion should never come from her, and the more she can curb his ardour by tactful suggestion, the healthier will he and the happier will she be, for nothing causes such an irritable, nervous state as excessive coitus. she will often have to give way in this matter, but must be firm on the necessity for preventing conception, for she can only bear a tainted child; her responsibility is great, and she must _insist_ that her husband use those simple methods which prevent conception, thereby ending in himself one branch of a worthless tree. this must be done at any cost, for her happiness is nought compared to the welfare of future generations. bitter though it be that no fruit of her womb may call her blessèd, it is less bitter than hearing her children call themselves accursèd. "so many severall wayes are we plagued and punished for our father's defaultes, that it is the greatest part of our felicity to be well born, and it were happy for humankind if only such parentes as are sounde of body and mind should be suffered to marry. an husbandman will sow none but the choicest seed upon his lande; he will not reare a bull nor an horse, except he be right shapen in all his parts, or permit him to cover a mare, except he be well assured of his breed; we make choice of the neatest kine, and keep the best dogs, and how careful then should we be in begetting our children? in former tyme, some countreys have been so chary in this behalf, so stern, that if a child were crooked or deformed in body or mind, they made it away; so did the indians of old, and many other well gouverned commonwealths, according to the discipline of those times. heretofore in scotland, if any were visited with the falling sickness, madness, goute, leprosie, or any such dangerous disease, which was like to be propagated from the father to the son, he was instantly gelded; a woman kept from all company of men; and if by chance, having some such disease, she was found to be with child she with her brood were buried alive; and this was done for the common good, lest the whole nation should be injured or corrupted. a severe doom, you will say, and not to be used among christians. yet to be more looked into than it is. for now, by our too much facility in this kind, in giving way to all to marry that will, too much liberty and indulgence in tolerating all sorts, there is a vast confusion of hereditary diseases; no family secure, no man almost free from some grievous infirmity or other. our generation is corrupt, we have so many weak persons, both in body and mind, many feral diseases raging among us, crazed families: our fathers bad, and we like to be worse." her husband will want much petting and caressing, and she must foster his love by lavishing on him much fondness, and ignoring amours as but the mischievous results of his restless, intriguing mind. she must let him see in an affectionate way that she can let others enjoy his company betimes, secure in the knowledge that she is supreme in his affections--cajolery that flatters his overweening vanity, and rarely fails. in anger, as in every other emotion, the neuropath is as transient as he is truculent. a trivial "tiff" will make him blaze up in ungovernable rage and say most abominable and untruthful things; even utter violent threats. he will not admit he is wrong, but like a spoilt child must be kissed and coaxed into a good temper, first with himself and with others next. at one moment he is in a perfect paroxysm of fury; five minutes later he is passionately embracing the luckless object of it and vowing eternal devotion. in a further five he has forgotten all his remarks and would hotly deny he used the vexing statements imputed to him. epileptics are morbidly sensitive, and reference to their malady must be avoided. victims are intensely suspicious, and a pitying look will reveal to them the fact that some outsider knows all about the jealously-guarded skeleton. resentment, distrust and misery follow such an exposure, for every innocent look is then translated into a contemptuous glance, and the victim detects slights undreamt of in any brain save his own. unless seizures are severe, no one should be called in; if they cause alarm, ask a discreet male neighbour to assist when necessary, leaving when the convulsions abate so that the victim is not aware of his presence. avoid the word "fit" and "epilepsy", and if reference to the attack be necessary, refer to it as a "faint" or "turn". living with a man liable to have a fit at inopportune times is a tremendous strain, and the soundest advice one can offer a woman thinking of marrying such a one is punch's--"don't!" we have painted the black side, but, tactfully managed, a neuropath will merge in the kindest of husbands, the most constant of lovers. the wife need not be unhappy. tactless, masterful women will fail, but no one is more easily led, particularly in the way he should not go, than a neuropath. a man with definite views of his own value will not be successful foil for "mother-in-lawing", nor remain quiet under the interference of relatives, who should remember that well-meaning intentions do not justify meddling actions. many a neuropath led a useful life and gained success in a profession, solely because his wife tactfully kept him in the path, watched his health, prevented him frittering away his gifts in many pursuits or useless repining, and made home a real haven. when the yolk seems unbearably heavy, the wife should remember her husband has to bear the primary, she only the reflected misery, for the limitations neuropathy puts on every activity and ambition, social and professional, are frightfully depressing. in spite of his peevishness her husband may be trying hard to minimize his defects and be a reasonable, helpful companion. "judge not the working of his brain, and of his heart thou can'st not see; what looks to thy dim eyes a stain in god's pure light may only be a scar brought from some well-fought field, where thou would'st only faint and yield." magnify his virtues and be tenderly charitable to his many frailties, for he is "not as other men" and too well he knows it. love at its best is so complex that it easily goes awry, but death will one day dissolve all its complexity, and when, maybe after "many a weary mile" "the voice of him i loved is still, the restless brain is quiet, the troubled heart has ceased to beat and the tainted blood to riot"-it will comfort you to reflect that you did your duty and, to best the of your ability, fulfilled your solemn pledge to love and honour him. to quote george eliot: "what greater reward can thou desire than the proud consciousness that you have strengthened him in all labour, comforted him in all sorrow, ministered to him in all pain, and been with him in silent but unspeakably holy memories at the moment of eternal parting?" surely, none! we have considered the mournful case of a wife with a neuropathic husband, and must now say a few words about the truly distressing fate of a husband afflicted with a neuropathic wife, for neuropathy in its unpleasant consequences to others is far worse in woman than in man. a man is at work all day, and his mind is perforce distracted from his woes, and, though he retails them at night to the home circle, they get so used to them as to disregard them, proffering a few words of agreement, sympathy or scorn quite automatically. with women the distraction of work is not so complete, for housework can be neglected, there are always neighbours and friends to listen to tales of woe and thus generate a very harmful self-pity, and women are not content to enumerate their woes, but demand the attention and sympathy of all listeners. many of the facts in the foregoing parts of this chapter apply with equal force to both sexes, but women being usually more patient, tactful, resigned and self-sacrificing than men, can--and often do--alleviate the lot of the male neuropath; whereas the absence of these qualities in the average man means that he aggravates, instead of alleviating, the lot of any female neuropath to whom he may be wedded. having taken her "for better, for worse" he will find her irritating, unreasonable, and unfitted to shoulder domestic responsibilities. her likes and dislikes, fickle fancies, unreasonable prejudices, selfish ways will cause trouble; he must be prepared for misunderstandings and feuds with relatives and friends, and on reaching home tired and worried, he is like to find his house in disorder, be assailed by a tale of woe, and perhaps find that his wife's vagaries have involved him in a tiff with neighbours. she will be fretful, exacting, impatient, and given to ready tears. sensitive to the last degree, she will see slights where none are intended, and a chiding word, a reproachful look, or a weary sigh will mean a fit of temper or depression. not only are men less gifted for "managing" women than vice versa, but women are far less susceptible to tactful management than men; a man, like a dog, can be led almost anywhere with a little dragging at the chain and growling now and then; a woman, like a cat, is more likely to spit, swear, and scratch than come along. consequently, it is almost impossible to suggest means of obtaining relief to one who has been luckless enough to marry, or be married by, a neuropathic woman. if the husband sympathize, the condition will but be aggravated; medicinal measures will only increase, instead of diminishing, the number of symptoms; indifference will procure such an exhibition as will both prove its uselessness and ensure the attention craved. * * * * * chapter xxvii summary to sum up: we have learnt that epilepsy is a very ancient disease due to some instability of the brain, in which convulsions are a common but not invariable symptom. its actual cause is unknown. heredity plays a big part, but there are secondary causes beside factors which excite attacks. various methods and drugs to prevent seizures have a limited use. first-aid treatment consists solely in preventing the victim sustaining any injury. neurasthenia is a disease due to nerve-exhaustion and poisoning from overwork and worry. its symptoms are many, but fatigue and irritability are the chief. hysteria is an obstinate, functional, nervous disease in which the patient acts in an abnormal manner, which is highly provoking to other individuals. the cure for hysteria and neurasthenia is solely hygienic, and depends mainly on the patient. the first step towards health consists in getting any slight organic defects remedied. digestion is often poorly performed. this must be remedied by thorough mastication and rational dieting. constipation is very inimical to neuropaths, and must be remedied. patients must pay careful attention to general hygiene. insomnia is exhausting and must be conquered. the effects of imagination are profound. suggestion treatment overcomes imaginary ills. drug treatment is either of very limited utility, or frankly useless. patent medicines are never of the slightest use. the rational training of neuropathic children is a very difficult but essential task. puberty and adolescence are very critical times. occupations and recreations must be wisely chosen. heredity is the primary cause of these diseases. as it cannot be treated, sufferers must not have children. character is abnormal in nervous disease. marriage is very undesirable. as a parting injunction, whether you are an epileptic or a neurasthenic, or a friend, relative, or attendant of such a one: "go thou softly all thy days!" * * * * * bibliography "oh!

i have had the pleasure of curing this book is respectfully dedicated beauty's fall. it was an image good to see, with spirits high and full of glee, and robust health endowed; its face was loveliness untold, its lines were cast in beauty's mold; at its own shrine it bowed. with perfect form in each respect, it proudly stood with head erect and skin surpassing fair; surveyed itself from foot to head, and then complacently it said: "naught can with me compare." when lo the face began to pale, the body looked too thin and frail, the cheek had lost its glow; the tongue a tale of woe did tell, with nerves impaired its spirits fell; the fire of life burned low. in the intestinal canal waste matter lay, and sad to tell, was left from day to day; and while it was neglected there it undermined that structure fair, and caused it to decay. the doctor's words i would recall who said: "neglect precedes a fall," and verily 'tis true; for ye who disregard your health, and value not that precious wealth, will surely live to rue. preface. the following chapters were contributions to _health_--a monthly magazine published in new york city. certain peculiarities of form and considerable repetition of statement--both of which the reader cannot fail to notice--are owing to the fact that about two-thirds of the chapters were written under the caption "auto-genetic poisons in the intestinal canal and their auto-infection." in revising these contributions for book form i have given to each chapter a caption of its leading thought; but i am convinced that repetition of some of the matters treated, especially if the repetition be in a somewhat different connection, is not such a very bad thing. i have used my blue pencil sparingly, and as a consequence the consecutive reader will find that constipation, diarrhea, biliousness, indigestion, auto-infection and proctitis are treated in nearly all the chapters--but with varying applications. therefore anyone suffering from one of these complaints would better read the whole book instead of only the chapter with the corresponding title. these pages were written for intelligent laymen by a specialist, during a busy, assiduous practice. i take such radical ground, however, going to the very root of the matter, that the general practitioner will do well to give my thesis his careful consideration; he should at least glance at the following introduction for the gist of my claim. contents. chapter i. page man, composed almost wholly of water, is constipated. why? 1 chapter ii. the physics of digestion and egestion 12

this book is proctitis, inflammation of the anal and rectal canals. hardly a civilized man escapes proctitis from the day of the diaper to that of death. the diaper is in truth chiefly responsible for proctitis, and proctitis is in turn chiefly responsible for chronic constipation, chronic diarrhea, auto-infection; and hence for mal-assimilation, mal-nutrition, anemia; and for a thousand and one reflex functional derangements of the system as well. the inflamed surface of the intestinal canal (proctitis) inhibits the passage of feces. absorbent glands begin to act on the retained sewage, and the whole system becomes more or less infected with poisonous bacteria. various organs (especially the feeblest) endeavor to perform vicarious defecation, and the patient, the friends, and even the physician are deceived by such vicarious performance into thinking and treating it as a local ailment. i cannot, accordingly, insist too emphatically that proctitis, the exciting cause, must be treated primarily if we would cure chronic constipation. millions of human beings are sent to untimely graves by these ailments. indeed, the body of nearly every human being is a pest-house of absorbed poison instead of being the worthy temple of a wondrous soul. all due to proctitis! intestinal ills chapter i. man, composed almost wholly of water, is constipated. why? naturally the mind of man was first educated to observe external objects and forces in their effects upon himself, and the external still continues to engross his attention as if he were a child in a kindergarten. fascinated by the without, he ignores the within. but, marvel of marvels, disease (which when looked at with discerning eyes is seen to be an angel in disguise) comes to enlighten him concerning the world within. disease gradually acquaints him with the fact that there are within him organs and functions corresponding to the objects and forces in the world without,--servitors in fact which must not be ignored under penalty of transforming them into foes to his well-being. disease makes him aware that by ignoring the claims of his inner relations he has been converting his very food, juices and gases into insidious and formidable poisons, which perforce he absorbs into his blood and tissues and circulates throughout his entire system. thus does the disguised angel admonish the ignorant that the rights of the inner world must not be ignored--that one's duties thereto cannot be neglected without disastrous consequences. thus does pathology, which is really physiology reversed, become the self-revealer _par excellence_. through digestion and assimilation the physiological process takes up the food, juices and gases, to support and augment the life of man. the pathological process, on the contrary, because the conditions for nutrition are ignored, reverses the upbuilding processes; and the organs of life wither, waste and weaken, until life goes out like fire unfed. man has been slowly learning to take sanitary measures in reference to everything that contributes to comfort in his surroundings, and hygienic measures in reference to everything conducive to stability in his health. through ages he has learned, by experience and experiment, of the changes that inevitably occur in such perishable nutritive substances as water, milk, meats, vegetables, fruits, etc., if they be left uncared for; and he has been led thus to the inference of the law of decomposition--or putrefactive and fermentative changes. idle substances, like idle minds, have decomposition and the devil for companions. substances confined in containers open to the air--ponds, cesspools, etc.--are every-day object lessons to man of the fact that the chemical changes they undergo furnish the conditions for breeding bacterial poisons, and that these poisons are a dread menace to animal life. if the reader will observe the analogy between the decomposition of substances in vessels or pools, and the decomposition of food in the reservoir called the stomach; and its further decomposition in a long canal (the small intestine), connecting the stomach with other receptacles called the colon and sigmoid flexure; and then the decomposition of _their_ contents; he will readily comprehend the chemical putrefactive or fermentative changes or bacterial action that take place in the organism, if for any reason the contents be confined. of the four chief elements that enter into the composition of living bodies three are gaseous, or convertible into gas. in the physical man water constitutes three-fourths of the weight of the body. this being so we realize why, notwithstanding our sense of solidity and weight, chemical changes occur quite as readily in our organism as in the substances we see about us. there are no waterproof walls in the body of man to impede the percolation of liquids freighted with promiscuous passengers from the alimentary canal; passengers designed to nourish the organs for which they have an affinity. but there are those that have no organic affinity, and these are tramps, vagabonds, and even murderers, disturbing and destroying the normal functions of the system. through extravasation, that is, through fluid infiltration of tissues, these passengers come to be one with us, and we make them part of our tissue; but some of the passengers are the demolishers of the living temple. water is universally present in all the tissues of the body, and it is indispensable for introducing new substances into the system and for eliminating the worn-out tissues and foreign substances. it is indeed important to emphasize the fact that properly to eliminate the foreign and waste products from the system requires, in a healthy person, at least five pints of water during twenty-four hours. the amount of gastric juice secreted in twenty-four hours is from six to fourteen pints; of pancreatic juice, one pint; of bile there are two to three pints, and of saliva one to three pints. it is estimated that the juices secreted during digestion in a man weighing 140 pounds amount to twenty-three pounds in twenty-four hours. these fluids are poured back and forth in the process of transforming food into flesh and eliminating waste material. in the alimentary canal there are vessels for holding fluid, semi-fluid and moist masses of substance, in all of which decomposition occurs if the substances be retained beyond the normal length of time. these vessels or reservoirs are the stomach, duodenum, small intestines, colon, sigmoid flexure, and too often the rectum. through the harmonious action of this intestinal retinue of servitors man is well equipped and qualified for health, and he in whom this harmonious subservience prevails is among the blessed and elect of mankind. but alas! the great majority of human beings are sufferers from the inharmonious and insubordinate action of these servitors. how many a human being suffers from _chronic constipation and indigestion_, the exciting causes of which are insidious, and the consequences a protean enemy to his happiness! medical writers on the subject of chronic constipation have assigned numerous causes, and likewise prescribed multitudinous remedies to the patient; but as a general rule this patient, after suffering various woes, if still surviving the many years of medication, rebels against taking further remedies and resigns himself to the chronic enemy on the best terms he can make with diet. for this large class of chronic sufferers we have good news; and for the class that have suffered five or ten years we have better news; and for the class of infants and children that have started on the road of ill-health we have real glad tidings. to know that there is only one chief cause for chronic constipation and its train of disorders, and that that cause overshadows all other causes combined, and is easily diagnosed and treated, is news long hoped and prayed for by a multitude of sufferers the world over. twenty years as a specialist in diseases of the lower bowels have demonstrated to the writer that chronic inflammation, and often ulceration, of the rectum and sigmoid flexure, in ninety-nine cases out of a hundred, is the cause of chronic constipation and the long army of ills resulting from it. and yet, as the reader is well aware, constipation has had many "causes," since the days of hippocrates, especially the abnormal condition of the liver. the etiology, that is, the exciting cause, of the inflammation of the anus, rectum, colon, etc., may date from the time a diaper was placed on the new-born infant. excoriations of the integument about the anus by the excretions of bowels and bladder indicate that the mucous membrane of anus and rectum demands local remedies, as well as the integument of the buttocks, and that it is not the liver which is at fault. the many applications of the diaper during the period of its use, and the frequently delayed removal at night or during long rides in baby wagons, railway trains or carriages, and during long social visits of the nurse; constipating foods, lack of drinking water, constipating medicines, followed by all sorts of purgatives, etc., are among a few of the direct causes of diseases of the rectum. a child at the age of eighteen months with a healthy rectum is most rare. the ten thousand and one chances for contracting disease of the anus and rectum do not cease with the period of infancy. the child is left pretty much to shift for itself as to regularity of eating and the evacuation of the contents of its bowels, wherein disease has already obtained a foothold. all kinds of foodstuffs, at all hours, with seeds, stones, etc., are poked into its stomach, followed by constipating remedies to quiet inevitable troubles, or brisk purgatives given with the hope of expelling the arrested contents of the bowels. is it any wonder that ninety-eight persons of adult age out of every hundred suffer more or less from chronic inflammation and ulceration of anus, rectum, sigmoid flexure, colon, or appendix? traumatic (externally produced) injuries to the mucous membrane of the rectum frequently cause inflammation, and hard pieces of bone, wood, seeds, imbedded in the feces, scratch, cut and bruise the tissues before and during the act of defecation. cold boards, stones, earth and other substances used as seats may produce inflammation of the rectum. there are many and various causes which may be the means of exciting inflammation of the anus and rectum later in life; but it is the writer's opinion that the cause can be traced back to infancy or early childhood, and that accidents or imprudence in after years merely excite an already-existing chronic inflammation. piles, fissure, itching pockets, tabs, prolapse, abscesses, fistulã¦, etc., are only the outcome and symptoms of a chronic disease which has incubated for fifteen, twenty or more years. none of this list of troubles produces constipation. it is the inflammation located at the middle portion of the rectum and extending into the sigmoid flexure that causes constipation; that protean monster which deranges more lives with nervousness than any other pathological condition to which the flesh of man is heir! chapter ii. the physics of digestion and egestion. a tree is simply an extension from its roots; and, in an analogous manner, man's body may be said to be an extension from the alimentary canal. does it not follow, consequently, that the digestive apparatus, from a physiological point of view, is the most important organ of the human body? it must be prime and paramount because all other organs depend upon it: it provides them with nourishment for preservation and improvement, and it punishes them--if they do not mind the laws of normality--by withholding its gifts, or by presenting these gifts in the form of poisons that impoverish, hinder and degenerate the system of organs. uncleanliness is surely one of the chief ways in which physiological thoughtlessness is exhibited, and due punishment will inevitably follow disobedience. foodstuffs are prepared for assimilation in the alimentary laboratory through the process of normal fermentation. is it not essential, therefore, that the connecting canals and receptacles be cleansed of the fermented debris that may remain unused and unexpelled, before more food be taken by the digestive apparatus? the all-important question is:--how soon and how well have the residuary part of the food (for some part will always be undigested or unassimilated), and the waste resulting from worn-out tissues of the various organs, been eliminated from the system? wisdom declares that it is not so much what we eat, but what and how well we eliminate, that decides the issues of health and disease. do the egesta pass out in the form of normal feces? three times in twenty-four hours foodstuffs are taken, and as many times the bowels should be freed of accumulated excrement and gases. does nature have her way, or do neglect and bad habits rule the assimilative and eliminative functions of the bowels? the habit of storing feces for twenty-four hours ought to concur and keep pace with a habit of eating one meal in the same period. household and laboratory receptacles in which fermentation has occurred are emptied and cleaned before fresh material is put into them. is not the same precaution more essential with the receptacles for digestion and egestion? they constitute our chief physiological economy; they are precious household and laboratory utensils; exceedingly precious, as we can purchase no other set when these are worn and wasted beyond repair. what marvelous possessions, and how reckless most of us are with them! neither love nor money will bring another "body"-house to us when this decays; when poisons or parasites infest it as the result of a pernicious diathesis, of debasing, destructive tendencies; in short, of unmindfulness! too often criminal negligence or the lack of proper convenience has brought on the habit of using the intestinal canal as a storehouse for dried feces, and the glands and blood-vessels as reservoirs for the absorbed fluid poisons from the feces that have been stored and thus dried. this baneful habit is general throughout civilized communities. it is this habit that has made the words "constipation," "indigestion," "diarrhea," etc., familiar and household subjects of complaint. medical writers agree that "constipation" is the most common malady that afflicts mankind; but they are also unanimous in preposterously attributing the cause to the abnormal action of the liver and the secondary symptoms of constipation. chronic constipation is the result of proctitis and colitis. proctitis, the inflammation of the rectal and anal canals, is the most common disease that afflicts the human creature from infancy to old age; and colitis is only the extension of proctitis to the colon. the scientific diagnosis of constipation predicates proctitis and sometimes colitis. it is declared that constipation is its primary symptom; and that diarrhea is one of its secondary symptoms, resulting from constipation. there is a legion of secondary symptoms of proctitis, all of which medical empiricism considers and denominates causes. as constipation is such an every-day complaint of almost everybody one meets, it will not tax our imagination unduly to conceive how it may be a frequent cause of diarrhea, which is only nature's effort to get rid of its useless and excessive burden of retained feces and gases. constipation, semi-constipation, and irregular action of the bowels, excessive fermentation, putrefaction, self-generated or auto-infection, are the factors to be considered. it is to be noted that in many cases diarrhea is simply an increased peristalsis of the bowels, often due to local and diffused irritation and often to inflammation of the mucous membrane (not infrequently with ulceration); all of these may be the outcome of fecal impaction. to make intelligible the physics of the digestive and egestive processes, we must understand the apparatus. one would naturally think that were the bends or curves of the large intestine undone, it would be found to be a long, straight, smooth canal or bore like a rubber tube. but such is not the case. the outer muscular longitudinal bands are much shorter than the musculo-areolo-mucous tube, an arrangement which brings about a transverse puckering of the gut and mucous membrane, thus forming valves, folds, sacs or pouches at short intervals along the canal. these transverse folds or valves inhibit the too hasty passage of the feces along the bowels by checking and retaining the egested product in the large recesses or pools between the folds; they thus serve as so many dams in the passage of feces toward elimination. this wise provision of nature to moderate the steady motion of the feces as they proceed toward the sigmoid flexure or receptacle, to wait there till there is a proper stimulus for expulsion, is wofully abused by man. he is quite willing to take foodstuffs three or four times a day, to fill the long row of intestinal pools between the dams with feces and gases in all stages of decomposition, not dreaming of the danger from developing bacteria and their absorption into the system. really he is inclined to eat at all times, yet begrudges a few minutes spent in a hurried effort to perform the act of defecation once in twenty-four hours. some of us even have our minds absorbed in reading while awaiting an "automatic action" of the bowels. what a contrast between the gusto and time spent in taking foodstuffs and the indifference and indolence regarding the action of the bowels, unless indeed severe biliousness or diarrhea reminds us strongly of our sewer of waste products. an attack of acute or chronic diarrhea is the penalty some pay for long inattention to the demands nature makes for intestinal cleanliness three times in twenty-four hours. constipated people, semi-constipated people, irregular people and twenty-four-hour people, are not healthy. they are constantly being poisoned by the abnormal products of indigestion and putrefaction resulting from fecal stagnation, which products enter the blood and circulate through every tissue of the body. all cases of proctitis are more or less accompanied by constipation and diarrhea. in all cases of chronic constipation i have found proctitis, and often colitis, and am forced to believe it is the most common and proximate cause of chronic constipation of the bowels. constipation being a primary symptom, there must of necessity follow numerous secondary symptoms, of which diarrhea well marks the progress of septic infection. some of the symptoms of infection are headache, megrim, vertigo, dyspepsia, foul tongue and mouth, back-aches, stiff neck, gnawing pain or numb feeling at the lower end of the spine, biliousness, bad odor from breath and skin, muddy complexion, cold hands and feet, jaundice, neurasthenia, loss of memory, drowsy feeling, pernicious anemia, emaciation, flabby obesity with pallor, capricious appetite, fits of great mental depression, palpitation of the heart, bloating of the stomach and bowels, disturbance of the kidneys, liver, lungs and mucous membrane in general, and especially chronic rhinitis and pharyngitis, which latter are among the first symptoms of imperfect alimentary excretion. as auto-intoxication (that condition of the system when it is continually poisoned, usually by one's own excretions) gains the mastery of the vital forces at any period of life, the mucous membranes are likely to be first affected by inflammation of catarrhal character; then the serous membranes of the body. mal-assimilation, mal-nutrition, cell-atrophy, are symptoms of the giving way of the vital energies to the invasion of the filth and bacterial poisons absorbed from the intestinal canal. on the inner surface of the alimentary canal, from the stomach to the colon, there are, it is estimated, over 20,000,000 rootlets (called glands, lacteals, follicles, villi), which take up intestinal juices as roots of a plant take sap from the soil. these millions of rootlets give a velvety appearance to the alimentary canal, like a nap or downy surface. intestinal rootlets of the small intestines, like vegetal rootlets, demand a certain amount of normal fluid and solid substance, free from noxious gas. it is the down or nap of fabrics, and not their body, that shows damage first. so it is with the frail structure of vegetal and animal life if not properly supplied with nourishment from day to day. there is probably in the vegetal bodies a continuous circulation of sap corresponding to the digestive circulating fluids of the alimentary canal. this circulation from the alimentary canal to the blood-vessels, and from the blood-vessels to the alimentary canal, involves a wonderful mechanism, facilitating the flow of several gallons daily from each to the other during the process of metamorphosis of food into flesh. you can thus see how inevitable it is that the functions of these millions of secreting and excreting rootlets will be disturbed by the clogging of the system with filth and bacterial poisons as a consequence of chronic constipation, biliousness and general foulness of the alimentary canal. through such disturbance nutrition is diminished, cell-atrophy progresses, and emaciation becomes more marked. the progressive destruction of these rootlets, involving the pathological change indicated, will be manifest in one of its results, either costiveness or diarrhea. often the power of properly digesting and absorbing the foodstuffs is so greatly diminished that the alimentary canal is about as useless as a soft rubber tube. millions on millions of these glands, lacteals and follicles in the stomach and small intestines, are destroyed like the rootlets of a plant or tree in unwholesome soil. the active circulation of the digestive fluids ceases, and the sufferer is said to be costive or to have chronic diarrhea. both symptoms are the outgrowth of many years of intestinal foulness, and indicate the degree and character of intestinal irritability and semi-starvation of the body, as a consequence of either the absorption of poisons or the excessive elimination of the vital substance of the body through diarrhea. chapter iii. the inter-dependence of anus, rectum, sigmoid flexure, and colon. physiologically, or in a normal state, the rectum is not a receptacle for liquids and feces but a conduit during the act of defecation. should, therefore, the feces have passed into the rectum and the desire to stool be not responded to--though the desire continue urgent--the feces will be returned to the sigmoid cavity by physiological action. when, however, the functions of the anus and rectum are disturbed by chronic inflammation, etc., the lower portion of the rectum becomes a more or less roomy pouch, a receptacle for feces and liquids; and instead of being physiologically empty it becomes pathologically distended, the result of spasmodic action or of more or less permanent stricture of the sphincter ani. see illustration in my book entitled _how to become strong_ (page 14). the putrid fecal mass of solid and liquid contents accumulated in the artificial reservoir at the end of the intestinal sewer, is one of the most common and serious pathogenic (disease-producing) and pyogenic (pus-producing) sources, which, by auto-infection, afflict man from infancy to old age. here--in the dilated and obstructed sewer--the ptomain and leucomain class of poisons, and many of the poisonous germs, led by the king of morbid disturbers, the bacillus coli communis, find another and last chance to be taken up by the absorbing cells of the mucous membrane and returned to the blood; with which they are carried to all parts of the body, clogging the glands, choking up the pores and obstructing the circulation, thereby causing congestion and inflammation of the various organs. the action of cathartics, laxatives, etc., fills the ano-rectal cavity with a watery solution of foul substances; this solution is readily absorbed into the circulation, aggravating the auto-intoxication (the established self-poisoned condition) already existing. danger does not end with the absorption of bacterial poisons, as we have to reckon with the deleterious effects of the various intestinal gases, resulting, with rapid augmentation of volume, from the putrefactive changes in the imprisoned feculent matter. a sphincter ani permanently constricted or irritable owing to disease results in an _abnormal_ receptacle just above the anal orifice (as shown in the illustration referred to); and a constricted and irritable rectum results in the impaction and dilatation of the sigmoid cavity, which is normally a receptacle, closed at its lower end by circular fibres separating it (the cavity) from the rectum and performing the function of a sphincter muscle. the rectal muscular fibres perform the office of a sphincter for the sigmoid cavity. the pathological changes that result in rectal impaction of feces usually extend to the sigmoid cavity. this cavity is 17-1/2 inches in length, shaped in a double curve like an italic _s_. civilized man should consider the disturbance to the functional action of body and brain, and the danger to health and longevity involved in the storage of effete and fetid matter. the disturbance and danger are enhanced when the tissues of the sigmoid flexure and the rectum are invaded by inflammation. a healthy action of the sigmoid receptacle depends on the rectum (a conduit six to eight inches in length); and as it is the universal verdict that disease of the rectum is one of the most common maladies that afflict the human race, it must inevitably follow that the feces will be abnormally stored in the sigmoid cavity, occasioning thereby habitual constipation which in turn brings on a host of functional disturbances throughout the system. the colon is a receptacle and a conduit some three feet in length (see ib. p. 13) and its action depends upon the ability of the sigmoid flexure to perform its function as a final normal receptacle; and this in turn upon the rectum, which depends on the sphincter ani. the colon does not appear to possess any digestive powers, though it is capable of absorbing substances. its function is not only to receive and forward the trifling residue of food which escapes digestion and absorption, but chiefly to excrete, through its own minute glands, the waste of the system coming from the blood. the excretion from these glands of the colon into the colon, plus the effete portion of the food received by the colon from the small intestine, approximate in weight from four to six ounces in an adult person in twenty-four hours; and of this amount passed 75 per cent is water; so that were the excreta dried the solid matter thus evacuated would not be found to weigh more than one ounce, or one and a half ounces. chapter iv. indigestion, intestinal gas, and other matters. we noted the fact that the "digestive secretions" in a man weighing 140 pounds amount to twenty-three pounds in twenty-four hours; now add to these the food and liquids taken in that period, and you will form some estimate of the work done in the human chemical laboratory in its normal and abnormal states. we noted further that substances confined too long in receptacles decompose and generate pathogenic poisons, that is, poisons productive of disease; and that the intestinal reservoirs are no exception to this law of putrefactive changes. how could we avoid drawing the inference, therefore, that disease-breeding germs, (generated in the organism and hence called "autogenetic"), and their auto-infection, _i.e._, absorption by the system, are an inevitable consequence of the undue retention and fermentation of the contents of these reservoirs: a consequence, in other words, of that intestinal uncleanliness commonly called biliousness, constipation, indigestion. by far the most common and immediate source of autogenetic (self-produced) poisons and their auto-infection, is some degree of chronic constipation and the deadening, smothering effects of constipation on digestion; an effect analogous to what takes place when we allow waste material or ashes to bank up against a fire, shutting off its draft. does the fire then continue to digest the coal? clog up the receptacle for ashes and the coal grows cold. dam up the colon or sigmoid and digestion is disturbed, diminished and debased, as evidenced by the local and general discomfort, and later by the train of inevitable disorders. indigestion is a household word. it has the widest range of all the diseases, because it forms a part of almost every other; and some diseases, such as chronic catarrh and pulmonary consumption, are in many cases produced by indigestion; which in turn had its source in chronic constipation caused by injury or inflammation of the lower bowel, as explained in our first chapter. diminished nutrition, impoverished blood, and loss of weight of from ten to twenty-five pounds, are the signs that indicate the coming disaster to the sufferer from auto-intoxication: the thoroughly poisoned state of the system resulting from auto-infection. vessels used by the dairyman and by those who furnish us with food products and liquids are kept scrupulously clean. why? because it is a question of loss of trade--of money. should these vessels be used when foul from fermentation or putrefaction of their contents, wealth would flee from the coffers of our purveyors, and the boards of health would, or rather should, take a hand in the matter. and these same purveyors, by the way, why do they care more for wealth than for health, their own and ours? but why are we all of us so neglectful of inner cleanliness and so careful of outer? the receptacles of the inner man reek with augean filth, and we cleanse them not. the immortal fountains of health and happiness are dammed, blasted and degraded by just this neglect of our imperative duty; the duty of furnishing full opportunity for the functions of replenishment and life, _by keeping the sewer passages clear_. are a sour stomach and foul intestinal canal fit receptacles for food and liquids? when our receptacles are in this condition, why do we add more material for the generation of poisons of the ptomain and leucomain classes, and morbid gaseous elements? it has been demonstrated that during fermentation an apple will evolve a volume of gas six hundred times its own size. what folly then to add to the fermenting mass! food taken under such conditions will produce results not hard to imagine. the gases that are commonly found in the stomach and small intestines are carbonic acid, nitrogen, oxygen and hydrogen; while, besides all these, sulphureted and carbureted hydrogen are found in the large intestine, causing in a normal state the necessary and useful distention of the alimentary canal. the writer has long regarded the abnormal production of gaseous substances in the intestinal canal from putrefactive changes as of itself not only a grave menace to health, but as a condition productive of morbific results of which we have still much to learn. the more or less constant and excessive distention of the whole or even of a part of the intestinal canal by gases is a serious condition, affecting as it does the various organs of the body, not only through the absorption of these gases into the general circulation but also through the reflex nervous reaction of these organs. it is astonishing what amount of mechanical force is exerted by the gases in the intestinal canal. they distend not only the muscular walls of the intestines and stomach but the strong abdominal walls as well, until the clothing worn has to be loosened for ease and comfort. this more or less extreme mechanical pressure may account for many cases of hernia, prolapse of the uterus, dislocation of various organs, disturbance of the circulation of the blood, and interference with the function of the nervous system, as indicated by its many protests in the way of aches and pains. naval-constructor hobson has lately demonstrated the dynamic power of gas confined in bags or receptacles in raising battleships; and it still remains for some physiologist or pathologist to demonstrate the morbid dynamic results of gases confined in the alimentary apparatus. the deleterious effect of the abnormal quantity of gases on all the organs of the body is imperfectly understood at present, but will be better apprehended when we are able to study more minutely the pathogenic poisons of the human system. it is known, however, that a stream of carbonic acid gas, or even of hydrogen, will paralyze a muscle against which it is directed. chapter v. key to auto-infection. in a previous chapter we stated that the average quantity of fecal discharge daily, by an adult, is from four to six ounces, and that of this weight 75 per cent is water. we referred of course to the daily passage from the bowels alone, not including that from the bladder. our studies have thus furnished us with the key wherewith to unlock the secret chambers of auto-infection. what is that key? it is the discovery that the system may possibly absorb as high as three-fourths of this feculent substance in the colon; that this absorption is made possible by an obstructed or sluggish intestinal canal where disease germs are propagated and lodged; that these germs, along with a certain amount of excrement, invade the tissues by absorption; and that we thus have the system constantly saturated with poisonous germs and filth, re-excreted, re-absorbed and re-secreted--no one knows how many times--by the various organs of the body. that the importance of intestinal cleanliness may be better appreciated, i will quote from the following authors on the subjects of excretion, absorption and circulation of the intestinal fluids. dr. murchison states that: "from what is now known of the diffusibility of fluids through animal membranes, it is impossible to conceive bile long in contact with the lining membrane of the gall-bladder, bile-ducts, and intestine, without a portion of it (including the dissolved pigment) passing into the blood. a circulation is constantly taking place between the fluid contents of the bowel and the blood, the existence of which, till within the last few years, was quite unknown, and which even now is too little heeded. it is now known, says dr. parker, that in varying degrees there is a constant transit of fluid from the blood into the alimentary canal, and as rapid absorption. the amount thus poured out and absorbed in twenty-four hours is almost incredible, and of itself constitutes a secondary or intermediate circulation never dreamt of by harvey. the amount of gastric juice alone passing into the stomach in a day, and then re-absorbed, amounted in the case lately examined by grunewald to nearly 23 imperial pints. if we put it at 12 pints we shall certainly be within the mark. the pancreas, according to krã¶ger, furnishes 12-1/2 pints in twenty-four hours, while the salivary glands pour out at least 3 pints in the same time. the amount of the bile is probably over 2 pints. the amount given out by the intestinal mucous membrane cannot be guessed at, but must be enormous. altogether the amount of fluid effused into the alimentary canal in twenty-four hours amounts to much more than the whole amount of blood in the body (which is 18 pounds in a man weighing 143 pounds); in other words, _every portion of the blood may, and possibly does, pass several times into the alimentary canal in twenty-four hours_. the effect of this continual out-pouring is supposed to be to aid metamorphosis; the same substance more or less changed seems to be thrown out and re-absorbed until it be adapted for the repair of tissues, or become effete." the reader will readily perceive how the system may become so charged that other organs of the body will vicariously attempt to play the part of a receptacle and conduit for the bowel, in order to excrete and eliminate ancient and offensive filth and bacterial poisons. the phenomenon of vicarious excretion may occur through the kidneys, lungs, skin, throat, nose, vagina, or uterus, thus keeping up chronic diseases and discharges that would not exist but for the chronic constipation or even for _incomplete action of the bowels each day_. over-distention of the rectum, sigmoid and colon, due to the pressure of gases and the impaction of feces, results in inflammation, ulceration, stricture, appendicitis, abscess, strangulation, intussusception, and abnormal ballooning or roominess in certain portions of these intestines or conduits. this roominess, though it becomes filled with feces, and often with liquids, permits of sufficient space for even the daily passage of feces without dislodging the stored contents. the fact that there is a passage daily deceives both sufferer and medical adviser as to the source of the poisonous condition of the system, and masks the origin of such disorders as chronic inflammation and ulceration of the nose, throat, lungs, stomach, duodenum, colon, appendix vermiformis, uterus, bladder, kidneys and edema of the legs. but these evidences of auto-infection are generally preceded and accompanied by a general loss of vitality and weight, by anemia, by a lowering of the resisting power of the organism--all of which produce a fit soil for the various diseases to which flesh is heir. as soon as the system becomes saturated with bacteria and effete matter, auto-intoxication results, in which condition there is but little or no store of vitality for resistance, reaction and recuperation. dr. bright has recorded several instances of fecal accumulation in the colon mistaken for enlargement of the liver and for malignant tumors. in one of the cases there was jaundice which disappeared after free evacuation of the bowels. frerichs also relates a case where enlargement from fecal accumulation was at first ascribed to a pregnant uterus, and subsequently, on the supervention of deep jaundice, to an enlarged liver, but in which purgatives dispelled the patient's anxiety about a diseased liver and at the same time her hopes for a child. dr. n. chapman, in his _clinical lectures_ (p. 304), says: "the feces sometimes accumulate in distinct indurated scybala or in enormous masses, solid and compact. taunton, a surgeon of london, has a preparation of the colon and rectum of more than twenty inches in circumference containing three gallons of feces, taken from a woman, whose abdomen was as much distended as in the maturity of pregnancy. by lemazurier, another case is reported of a pregnant woman, who was constipated for two months, from whom, after death, thirteen and one-half pounds of solid feces were taken away, though a short time before between two and three pounds had been scraped out of the rectum. cases are reported by dr. graves of dublin, which he saw in women, where from the great distentions in certain directions of the abdomen, the one was considered to be owing to a prodigious hypertrophy of the liver, and the other of the ovary; in the latter of which he removed a bucket-full of feces in two days. mr. wilmot of london has recently given a case where a gallon of matter was lodged in the cã¦cum, and the intestines perforated by ulceration." dr. pavy, in his treatise on _the functions of digestion_ (p. 232), writes: "the morbid conditions that constipation may occasion are of various kinds. under an undue retention of fecal matters within the colon noxious products may be formed there, and act as irritants upon the mucous coat, setting up inflammation, followed by ulceration. it is to be here remarked that fecal matters are sometimes retained in the sacculi or pouches of the colon, and may give rise to the circumstances referred to, whilst a passage exists along the centre of the canal that shall permit a daily evacuation to occur. the dejections, even, may be loose in character, and still the same sequence of events ensue. from the irritating influence of preternaturally retained feces, colicky pains are, as a rule, induced, and the ultimate effects may be such as to lead to the production of fatal inflammation. "the effect of constipation upon the muscular coat of the bowel is, through distention to which it is subjected, to weaken or deteriorate its evacuating power. as the result of a great amount of distention, like as happens in the case of the urinary bladder, more or less complete paralysis is induced. from the prolonged retention of fecal matter accompanying constipation, excrementitious products that ought to be eliminated become absorbed and thereby contaminate the contents of the circulatory system. as the result of this contamination, the secretions become vitiated, and a general disturbance of the conditions of life is produced. the action of the liver becoming deranged, its eliminative office is imperfectly discharged, and thus sallowness of the face and a bilious-tinged conjunctiva are produced. a coated tongue, foul mouth, loss of appetite, and other dyspeptic manifestations, accompany the general disorder of the digestive organs that prevails. the accumulation existing in the colon leads to a sense of distention and uneasiness in the abdomen. the kidneys vicariously discharge products that ought to have been eliminated by the alimentary canal. in this manner the urine becomes preternaturally loaded. from the contaminated state of the blood the functions of animal life also become disturbed; and hence the lassitude, debility, headache, giddiness and dejected spirits, that form such frequent accompaniments of constipation.... a distended cã¦cum, colon, and rectum may also, by the pressure exerted upon the nerves and vessels of the lower extremities, be the cause of numbness, cramps, pains and edema of the legs. the edema occasioned by constipation, if not exclusively confined to one side, will in all probability be decidedly greater in one leg than in the other." case (from _gaz. mã©d. de paris_, july 20, 1839): a woman of fifty was troubled with habitual diarrhea and frequent calls to urinate, in which urine could be discharged only by drops. after six years of suffering and unsuccessful use of remedies, she was examined for the first time per anum, and an accumulation of fecal matter discovered, forming a mass the size of an infant's head. this was removed and found to weigh four pounds. she then got well. chapter vi. how auto-infection affects the gastric digestion, and vice versa. frederick the great said that all culture comes through the stomach. this saying emphasizes pithily the dependence of psychology upon physiology. the stomach with the intestines is certainly the source from which every portion of the body receives its nourishment and most of its diseases. the physiological _plus_ and _minus_ processes leave their reflex on the mind. prof. ch. bouchard, in his lectures on auto-intoxication (oliver's trans., p. 14), says: "the organism in its normal, as in its pathological state, is a receptacle and a laboratory of poisons. amongst these some are formed by the organism itself, others by microbes, which either are the guests, the normal inhabitants of the intestinal tube, or are parasites at second-hand, and disease producing." in the preceding chapters we have mentioned some of the most common cases of retention of excreta in the rectum, sigmoid cavity, colon, cecum, duodenum and stomach, and how the consequent foul conditions often resulted in diarrhea. auto-infection impairs the functions of every organ in the body, by clogging the pores with poisons and filth. by the transfer of disease germs from one infected, that is, tainted, contaminated part of the body to parts that were free from infection, the kidneys, mucous membrane and skin receive these unnatural products, and their functions are disturbed thereby. the disturbance of the various organs throughout the system sets up such a multiplicity of symptoms that one gets the impression of a pandemonium--a veritable council-hall of evil spirits. the visitation is omnipresent. infliction, misery, are everywhere. the taint of auto-generated intestinal morbific products, carried and communicated to the remotest parts, manifests itself now here now there as if it were a local trouble, and it is difficult therefore, nay, impossible, to classify scientifically the symptoms of auto-infection. a classification, though necessarily imperfect, will aid in the diagnosis and treatment of the various abnormal conditions of the stomach and intestines, that is, of mal-digestion. the sympathy, good understanding and responsiveness between the brain and the digestive apparatus are so close and intimate that the physician must take into consideration the inter-relationship of these organs before deciding which one is reporting reflex nervous symptoms, and which direct symptoms. plutarch says in one of his essays: "should the body sue the mind before a court judicature for damages, it would be found that the mind had been a ruinous tenant to its landlord." the digestive apparatus is, or should be, a farm for the mind, but unfortunately it usually has to wait twenty or more years before the tenant understands how to cultivate it for the uses of his intellectual and esthetical life. i have referred to the fact that the most common causes of constipation, indigestion and other foul conditions of the alimentary canal favorable to the production of autogenetic poisons and their auto-infection, are such common and every-day matters, so familiar to almost every one that the victim, the parents and the physician feel no alarm of the coming danger for years. during these ignorant and innocent years the poison and filth were being absorbed, infecting the system with their morbific taint and lowering the quality of the blood and lessening its quantity, producing the state known as anemia. associated with progressive anemia is mal-assimilation, improper nutrition, ebbing of the nervous and vital forces and the lessening of the secretory, excretory and digestive powers. by the time the poor victim is weighing fifteen to twenty-five pounds less than he ought to the symptoms of ill-health are sufficiently alarming to compel the sufferer to seek medical aid for disease of the stomach, bowels, liver, kidneys, lungs, etc. _slow digestion_ is perhaps the most common form of functional disturbance of the stomach, due to an insidious auto-infection for years. the eyes and the skin begin to show the effect of the poisonous infection. the skin becomes dry, pale and muddy in color; has more or less annoying eruptions, and exhibits a jaundiced appearance. the body is ill nourished, the nervous system depressed, the blood impoverished, the memory failing, the general appearance languid, irritable, anxious. what a household picture this is to every one of the human family! but let us fill it out somewhat more fully. note how the undue delay of food in the stomach occasions a sense of weight and oppression, the feeling beginning about an hour after a meal and continuing for hours, sometimes attended with fermentation and sometimes without it. at times there is a feeling of drowsiness due to the absorption of an excessive amount of the gases which distend the stomach and bowels, and this absorption is accompanied by pains in the stomach, head, between the shoulders and in the region of the heart. sleep is disturbed by dreams, or one is awakened with a feeling of numbness and palpitation of the heart. at times the urine is scanty, strongly acid or high-colored. the tongue is more or less foul, with white or creamy coating. now and then tasteless or saltish eructations occur. the appetite may be too good, or there is no appetite at all. note the careworn expression, the wondering what to eat, what to drink or what remedy to take. so between much worse and some better, the trouble continues--both of body and mind. _indigestion_, however, with undue formation of acids proper, or acids unnatural, to the stomach, is a much more annoying affliction than slow digestion. the sufferer from indigestion may be debilitated, anemic, may have a general want of tone; or he may be a more or less vigorous and plethoric person. in some cases flatulence is very troublesome. but the most usual symptoms are heartburn, acid eructations that produce burning sensations, sour taste at intervals or constantly in the mouth, setting the teeth on edge. in the more vigorous or plethoric sufferers a gouty diathesis may exist, which may result in a tendency to inflammation, bringing on neuralgia, rheumatism, gout, etc. tongue more or less foul; uric acid in the system; confusion in the mind; headaches; pains in the loins, legs and feet; in fact, more or less shifting pains everywhere: these are the common exhibits of indigestion. on the whole, the sufferer is a victim to an irritable body and a fretful mind, necessitating the cultivation by him of patience and the effort to be agreeable. besides the symptoms mentioned, indigestion may also be accompanied by gastric pain or by uneasiness at the pit of the stomach. it may be a sense of fulness or tightness, or a feeling of distention or weight, or again, a feeling of emptiness, goneness or sinking. now and then there are burning, tearing, gnawing, dragging sensations under the breast-bone; and there is a general complaint of a capricious appetite, heartburn, vomiting, nervous headache, neuralgia and cold extremities. other symptoms are pain from lack of food at the proper hour, or from food taken at the improper time; both of which practices may be followed by flatulency, occasioning a swollen, drum-like condition of the stomach and abdomen; the body of the tongue will be coated white, while the edges will present a redder appearance than in health. _impaired digestion_ with nervous symptoms--in which the morbid sensibility of the mind is apparently the greatest--is called _hypochondria_. this class of sufferers, whose bodily and mental ills and morbid fears are so chaotically interwoven, are deserving of much consideration. so numerous are their fears and so fertile are their reasons for the many changes they arbitrarily make in their efforts to get well or keep from getting worse, so obstinately sure are they of being always right--that we can but give them our sincerest pity. in some cases the functional troubles of the stomach and mind are aggravated by disease of the pelvic organs, which adds to the depression of the mind through nervous sympathy with the abdominal organs. dr. cullen says on this point:- "in certain persons there is a state of mind distinguished by a concurrence of the following circumstances: a languor, a listlessness, or want of resolution and activity with respect to all undertakings; a disposition to seriousness, sadness and timidity as to all future events; an apprehension of the worst or most unhappy state of them; and therefore, often upon slight grounds, an apprehension of great evil. such persons are particularly attentive to the state of their own health, to every smallest change of feeling in their bodies; and from any unusual feeling, perhaps of the slightest kind, they apprehend great danger and even death itself. in respect to all these feelings and apprehensions, there is commonly the most obstinate belief and persuasion." (quoted in leared, _on imperfect digestion_, p. 106.) chapter vii. how auto-infection affects intestinal digestion, and vice versa. intestinal indigestion is a more common form of functional disturbance than is gastric indigestion. it is a well established fact that the greater portion of the digestive work is done beyond the stomach, in the duodenum, by the hepatic and pancreatic fluids. the duodenum--very properly called the _second stomach_--has none of the peculiar characteristics of a receptacle that receives crude substances--the office of the stomach. much greater sensitiveness characterizes the digestive canal than the stomach; which is accounted for by the fact that a network of nerves, forming the sympathetic system, surrounds the bowels. the symptoms of intestinal indigestion are not always clearly defined and distinguishable from gastric indigestion, especially as the two are frequently associated. the cecum, more than any other portion of the digestive canal, resembles the stomach, and it secretes an acid, albuminous fluid having considerable solvent properties. it is to be observed that as the cecum is only three inches in length and two and a half in diameter, and as its contents are necessarily propelled in opposition to gravity, a slight casualty will hinder or obstruct the upward movement of the pultaceous mass of the effete ingesta. the turning point in the ascending colon affords another ready hindrance to the upward and onward movement of this mass; and the gases and ancient feces beyond the turn conduce to further sluggish peristalsis, bringing about more or less obstruction and reflex irritation of the remaining length of intestinal canal. undue retention of the contents of the cecum, and the disturbance and obstruction of the duodenum by the pressure incident to the distention of the colon with feces and gases, lead to congestion, inflammation and occasionally to ulceration of the mucous membrane in various parts of the intestinal tube. this condition of affairs increases the occlusion (closing) of the bowels, but makes very easy indeed the entrance and propagation of micro-organisms in the sub-mucous coat of the intestine. the conditions are now ripe and rife for auto-infection. which of the following microbes are the most active agents of progressive auto-infection: the streptococcus lanceolatus, the bacterium pyogenes, the bacillus subtilis, the staphylococci, the bacterium coli commune? they all play a part in the game, reducing the body in time to a charnel-house. or are such substances as putrescein, cadaverin, skatol or indol--which are derived through chemical change in the putrescent mass--contributors to the spread of the poisonous taint throughout the system? any single one or a group of the fifty or more bacterial poisons may be the responsible agents in the ensuing auto-infection. chemical analysis of the gases resulting from decomposition reveals oxygen, nitrogen, hydrogen, carbonic acid, protocarbonated hydrogen and sulphureted hydrogen, ammonia, and sulphate of ammonia. leucin, tyrosin, lithic acid, lithates, xanthin, cystin, keratin, sulphureted hydrogen, etc., are deposits in the urine and are signs of the derangement of the intestinal canal and liver. the external symptoms observed are the following: the tongue is large, pale, flabby and indented by the teeth at the edge of the anterior third, while its surface is white and the papill㦠often enlarged; the appetite may be excellent, though there is great functional derangement of the liver with lithemia, so that the sufferer is tempted to eat what he knows from experience will disagree with him; a bitter coppery taste in the mouth, due to taurocholic acid--a common symptom of lithemia or of imperfect oxidation of albumen; emaciation, fatigue, depression, headache, buzzing in the ears and deafness, disturbance of sight, loss of memory, faintness and vertigo, very marked in some cases; sometimes tenderness and pain under the cartilages of the right ribs; the fretting of the sensitive surface of the bowels by imperfectly digested, semi-putrescent food, resulting sometimes in convulsions, coma, paralysis, or in fetid diarrhea of an acid character producing a burning sensation or pain of the anus when the discharges are being passed; rumbling and twisting sensations in the region of the navel occurring with flatulency, and occasionally colicky pains which at times are so severe as to simulate poisoning. in some people certain articles of food, without being either toxic or putrid, induce indigestion and the production of microbes in quantity amounting to one third of fecal dejections. prof. ch. bouchard says: "the consequence of this development of acid in the whole length of the digestive tube is an inflammatory condition. we notice catarrh of the stomach, ulcerative gastritis, to which patients often succumb after twenty-five years of _bad stomach_; these are the _false cancers_, as they are called, or malignant gastritis without tumor. the large intestine is inflamed; around the fecal matter are seen glairy secretions and sometimes blood (membranous enteritis)." (op. cit., p. 159.) in chronic inflammation of the rectum and colon there is more or less discharge of mucous, and in some cases of membranous, desquamation, with yellow or bloody mucus. the shreds, cords or complete tubular casts are discharged constantly or at varying intervals. the quantity and character often alarm the sufferer. the discharge is nothing less than a thick, tenacious mucus that had formed a thin coating on the inflamed mucous membrane, and become exfoliated in casts or thin shreds--the result of many years of morbid intestinal exaggerated action. microscopical examination of the desquamated intestinal membrane and mucus from a man forty years of age, revealed the following products: crystals, mostly complete; incomplete phosphates, very numerous; mucous shreds in abundance; fat globules and granules, numerous; anal epithelia; red blood globules, few; connective tissue, scanty; pus corpuscles, very few; margaric acid and detritus (substances resulting from the destruction or wearing away of the part); undigested material, mostly cellulose; leptothrix threads, micrococci; and the bacillus coli communis. diagnosis: foul, undigested material, due to a chronic inflammation of the lower intestinal tract. the microscopical examination of mucus and desquamated membrane from a woman sixty-five years of age, disclosed that she was suffering from proctitis and colitis. she wrote: "please tell me how long this mucous discharge must continue. i am alarmed at the quantity of membrane, cords, casts, etc., in my excreta, and i think that if this process goes on much longer there will soon be no bowels left to purify." this letter was written some weeks after contracting a severe cold, which accounts for the unusual amount of exfoliation and mucus. the sample she sent contained a large quantity of mucus, both threads and corpuscles; with a moderate number of epithelial scales, partly anal and partly intestinal. pus corpuscles were present in small numbers; also vegetable fibres, fat, starch, muscle fibres and cellulose--the remains of undigested material. in the membranes themselves no micro-organisms were found; in the pieces containing undigested material the bacillus coli communis was found as well as micrococci, and the bacilli of putrefaction (secondary formation) were seen. chapter viii. the cause of constipation and how we ignorantly treat it. one of the best preparations for active life is a first-class intestinal canal. "an old scotch physician," says sir astley cooper, "for whom i had a great respect and whom i frequently met in consultation, used to say to me as we were about to enter our patient's room together, 'weel, misther cooper, we ha' only twa things to keep in meend, and they'll serve us for here and herea'ter; one is au'ways to hae the fear o' the laird before our e'es, that'll do for herea'ter; and th' t'other is to keep our boo'els au'ways open, and that'll do for here.'" a person whose mind is devoted to the realization of ideals, and whose body has a set of bowels that perform the act of defecation twice every twenty-four hours is doubly prepared for a useful life. "if thou well observe in what thou eat'st and drink'st, seek from thence due nourishment, not gluttonous delight, till many years over thy head return: so may'st thou live, till like ripe fruit thou drop into thy mother's lap, or be with ease gathered, not harshly plucked, for death mature." milton's advice in poetic lines is all very well for those who have escaped chronic inflammation of the lower bowels, an ailment common and troublesome even under the very best dietetic regulations. inflammation having once penetrated the circular and longitudinal muscular fibres or bands of a section of the intestine, all hope of a comfortable existence is at an end, for such inflammation will bring on constipation and constipation nervous misery. it is inevitable that inflammation should determine this outcome since it induces spasmodic contraction of the muscular walls of the tube, lessening the bore or closing the portion of the canal invaded. plastic infiltration takes place in the walls of the gut, thickening and binding them together; or, if the inflammation be of a simple catarrhal or atrophic nature, the plastic infiltration will more or less bind the circular muscular bands of the gut together in their abnormally contracted state! the presence of feces and gases above the zone of the disease will increase the irritation and contraction of the affected portion of the intestine. consequent upon these changes wrought by inflammation, gases and excrementitious material are perforce imprisoned in the intestine, inducing constipation, foul fermentation, flatulency, diarrhea, indigestion, nausea, loss of appetite, sick headache and, in fine, autogenetic poisons, the source of auto-infection, ending in auto-intoxication, the chronic poisoned condition of the system. since the most common cause of chronic constipation, internal sluggishness and uncleanliness, is known, too much cannot be said in condemnation of the wide-spread abuse of "liver and atony persuaders" and the use of irritating suppositories and dilating bougies, candles, etc. the numerous and various drastic purgative nostrums--which literally fill our medical literature--and the universal demand for them, are evidence of this very common disease, which disease is rendered worse by the drugs taken for the relief of a foul intestinal alveus. an abnormal amount of watery secretion is forced by the drug into the foul canal, to mix there with its contents, of which the major portion is retained and re-absorbed into the system. and to make the bad condition and treatment worse, all such sufferers, as a rule, drink very little water, some scarcely any. the demand for an irritating stimulus to "open the bowels" (the exciters contribute to close them) is largely due to the popular error in thinking, "i can treat my own bowels quite as well as the doctor, if not better." no intelligent person would think of stimulating and irritating daily an inflamed region of tissue on the outer portion of the body; yet this is precisely what intelligent persons do when they habitually use liver and peristaltic persuaders. the primary disease in the lower bowels and the consequent symptoms are gradually aggravated as the "physic" habit is formed. as in the case of opium fiends and drunkards, so with habitual cathartic drug-users, should they be suddenly deprived of the accustomed artificial stimulus and irritant they become absolutely miserable, mentally and physically. it is a well-known physiological fact that every artificial stimulation of the intestines is followed by a corresponding loss of vitality and reaction. now that the almost universal cause of undue retention of foul, effete matter has been ascertained, it is important to communicate to the world at large the best means of cleansing the bowels without increasing the local primary disease and its annoying symptoms. that external physical cleanliness is next to godliness is an apt proverb. that internal physical cleanliness is nearer to godliness no one will deny. water is a universal solvent and therapeutic agent and is therefore indispensable in the cleansing and purifying of the integument and mucous membrane of the body. a large quantity of water is necessary to carry on the functions of the animal economy. water enters every cell and fibre of the living organism, aiding in nutrition and in the elimination of worn-out tissues which if retained turn into poisons. it is really not an intelligent but rather a barbarous practice to prescribe liver and intestinal exciters for the purpose of throwing into the alimentary tract a sufficient quantity of watery excretions to "cleanse itself"; to succeed they must first soften and liquefy the dry, hardened feces and scybalous masses (little ancient, bullet-like formations) imprisoned above an inflamed and fevered lower bowel, even colon. normal feces consist of 75 per cent water; and when unduly retained in the colon much of this fetid percentage is absorbed into the system. then drugs are prescribed to liquefy the hardened putrid remnant and absorption begins again: a fact very shocking to a sensitive, even sensible, person. chapter ix. cures for constipation: "fearfully and wonderfully made." diseases of the anus and rectum are very common, very numerous and of very critical consequences. this is especially true of the disease of chronic inflammation, one of whose symptoms is piles or hemorrhoids. in the writings of the early greek and roman physicians will be found minute descriptions of the latter disorder. but on the whole, the most important symptom of chronic inflammation of the lower bowel, and the most far-reaching in its morbific results, is that protean monster, chronic constipation. it deranges more lives, from infancy to old age, than any other pathological condition that can be named. for the cause and cure of that mere symptom of a disease, constipation, the so-called scientific physicians, from the early history of medication to the present time, have had one immutable theory as to the leading cause, and one grand motto as to the "safe and sure" cure. they have always prescribed remedies for this malady on the theory of portal congestion and hepatic derangement, and hence their supreme motto: "_physic! physic!! physic!!!_" the layman naturally adopted the theory and the motto of his medical advisers; hence in his self-medication and also under advice he consumes such vast quantities of purgative nostrums. i have just received some medical literature beginning with the usual salutation--"dear doctor"--setting forth a new and remarkable theory of the cause, and an original motto for the cure, of constipation. its authors have discovered that the "rectal nerve-tissues" are hungry, torpid, anemic, and to overcome the "atony" they must be "_fed! fed!! fed!!!_" "the greatest of physical ills in america," we are informed, "is digestive torpor or semi-paralysis, originally induced by a kind of starvation of the intestinal nerve-tissues. one of its most prevalent forms is constipation," caused by "local torpor or semi-paralysis, dependent upon an anemic condition of the nerve-tissues of the rectal region." by "feeding directly" the limpid, bedraggled rectum and colon, they receive their "appropriate nutriment, by which comes added vigor,"--the nutriment the stomach and the rest of the system had failed to furnish on account of constipation, excessive fermentation, indigestion and auto-infection. to overcome this "atony" of two or more feet of the lower bowel, a little "nutritious" suppository, weighing twenty grains, is a "specific." it is claimed to cure chronic auto-infection and the spasmodic occlusion of the lower bowel! the excessive activity of all the region invaded by the chronic inflammation and the local irritation are perpetuated by such "feeding" instead of allayed! does it not stand to reason that there is already too much activity, and that when the irritability reaches a certain stage diarrhea or looseness of the bowels must result? twenty grains prescribed once a day to nourish an organ (the rectum) six to eight inches in length, and from one and a half to two and a half inches in diameter! when for two to three feet the lower bowel requires nourishment, a suppository night and morning is prescribed! however, the new treatment has the merit of some consistency between the diagnosis and the treatment, notwithstanding both are wrong. chronic inflammation of the lower bowel causes, as i have pointed out, excessive activity and thereby excessive nutrition of the tissues involved in the morbid process. but sphincter ani gymnastics have been suggested by some one who thinks chronic constipation is owing to a lack of muscular activity of the lower bowels; and the following reason is given: "physiological experiments have shown that rapid voluntary movements of the external sphincter ani and the levator ani produce very active peristaltic movements of the large intestine. this effect is produced by the mechanical excitement of the plexus myentericus of auerbach. this curious automatic center lies between the two muscular coats of the intestine and controls the peristaltic movements. a person suffering from constipation should make powerful movements of the sphincter ani, and of the levator ani, in as rapid succession as possible, continuing the exercise for three or four minutes or until the muscles are fatigued. the time chosen for this exercise should be either before breakfast or an hour after breakfast, according to the natural habit of the individual in respect to the evacuation of the large intestines." there are surgeons who recommend stretching and paralyzing the external sphincter muscle; and if they are correct in their diagnosis and treatment, those who prescribe _bile-bouncers_, and those who prescribe "_nutrient suppositories_," and those who prescribe the use of _rubber bougies_ and _candles_, should call a convention (to meet in, say, new york city) to discuss the subject and see if they cannot agree to inform the people that constipation is a sign of, or a factor in, the evolution of the human race. those who believe in the gymnastics of man's ears and of his sphincter ani and the therapeutic merits of this and of that could readily assent to the same glorious conclusion. strange to say, there are in new york physicians who are in the habit of inserting a rubber bougie up their patients' rectums two or three times a week for the cure of constipation. some, more bold, intrust the bougie performance to the patient in order that a daily dilatation and stimulation may be kept up until "recovery from the disease is effected." others, more original, order the patient to insert a candle some six inches in length up the rectum and allow it to remain ten minutes, with the hope of a "rapid cure." a mrs. p----, who had used the candle treatment for a great length of time by order of her distinguished physician, once consulted me. on examination, i found her afflicted with atrophic catarrh, chronic constipation and anal ulceration, from which she had suffered for seven years, with but little intermission from pain during each day of that entire period. chapter x. biliousness and bilious attacks. commonly the source of chronic gastro-intestinal uncleanliness, of dyspepsia, of autogenetic poisons and auto-infection is inflammatory occlusion--more or less permanent or spasmodic--of some part of the lower bowel. many years of auto-infection will exhibit such diseased symptoms as poor appetite, bad digestion, impoverished blood, emaciation, etc., accompanied by increased virulence of the catarrhal discharge of mucus, shreds, etc., and a mind and body sinking down to the morbid plane of hysteria, hypochondriasis (fear of illness) and neurasthenia (debility of the nervous system). biliousness and bilious attacks are evidence that there is a more or less constipated condition, that there has been an occasional imprudence in diet, and that the dreadful sense of fulness up to the end of the tongue is a faithful report of the state of affairs. what is it but a full foul condition of the digestive canal, a complete blockade of the canal from the rectum or colon to the stomach, making the victim feel that there must be something done in the way of cleaning out? he fears that the condition will be followed by fever--not infrequently this is the case. biliousness is usually supposed to be occasioned by hindrance to the flow of bile, and the conclusion is drawn that the liver requires stimulating. this supposition is erroneous and very far from pathological veritude, as the liver, like the other organs, is merely _a secondary sufferer from the over-eating and the closed sewer_. "the _bowels_ with sullen vapours cloud the brain, and bind the spirits in _their_ heavy chain; howe'er the cause fantastick may appear, the effect is real, and the pain severe." the bilious attack is usually noticed in the morning before food has been taken. the tongue is heavily coated and often so foul that it is necessary to scrape it and cleanse the mouth of disagreeable taste. eructations, nausea followed by vomiting of undigested foul-smelling food, and if the vomiting be long-continued, mucus from the stomach and bile that had accumulated in the duodenum, are sufficient evidence that there was no torpidity of the liver. there is likewise more or less headache, neuralgia, giddiness, hebetude (state of mild stupidity), dejection, confusion of the senses, skin disease, acne rosacea (scarlet redness of the nose and cheeks), eczema, etc. the headache may be seated in the centre of the brain and extend to one or both eyeballs and be increased by stooping. should diarrhea occur many of the annoying symptoms are likely not to be present. in this form of indigestion the bowels are often much constipated, which is usually only a more marked symptom of chronic constipation. the system now and then vigorously rebels against this chronic condition and an acute bilious attack is the evidence of such rebellion. the whole digestive canal is involved in the rebellion, resulting in the symptoms described and also in a morose, petulant and querulous temper, accompanied by a peculiar, despairing expression,--partly due, perhaps, to regrets of having only _one_ digestive apparatus,--or in some cases, perhaps, of having _any_. that the character and disposition may be materially influenced by such a state of the bowels is well established. plato believed that "an infirm constitution is an obstacle to virtue, because such persons think of nothing but their own wretched carcasses"; for which reason he contended that ã�sculapius should not undertake to patch up persons habitually complaining, lest they beget children as useless as themselves, being persuaded that it was an injury both to the community and to the infirm person himself that he continue in the world, even though he were richer than midas. acting on this well-known fact, the celebrated voltaire, in one of the articles in his _philosophical dictionary_, has very humorously ascribed half the evils of europe to the intestinal irritations of the public men of the age. "let the person," he adds, "who may wish to ask a favor of a minister, or a minister's secretary, or kept mistress, endeavor previously, by all means, to ascertain whether they go to stool regularly; and, if possible, to approach them after a comfortable evacuation, that being a most propitious moment, one of the _mollia tempora fandi_, when the individual is good-humored and pleased with all around him." chapter xi. king liver and bile-bouncers. the "house not made with hands"--the human body--has, like the house made with hands, _its_ sewer system, which is over twenty-five feet in length. to cleanse (?) this wonderfully delicate, tortuous and extended passage-way of waste material, civilized man knows no better than to put in at the top of the house, purgatives, cathartics, bile-bouncers, etc., with one hope and purpose in view, namely, that these policemen go searching, scouring and hustling the intestines in the greatest possible haste, in order to remove an obstruction about three hundred inches distant from where these "forcers" had entered the intestinal sewer. with mercury as a scavenger the work is pretty thoroughly done, though extra care has to be taken that some of the teeth may remain after the victim survives the additional intestinal inflammation occasioned by its drastic measures. traits acquired by the father are inherited by the children; present-day doctors follow early practitioners; they still pour in many and various decoctions at the top of the obstructed sewer of the human house to dislodge accumulated gases and feces at the bottom. the plumber treats the sewer of the house of brick and stone more wisely. our fathers partook of laxatives, cathartics, purgatives, and in consequence we start in life with teeth, intestines, appendices, out of gear and nervous systems on edge. with unconscious stupidity we continue the fatuous practice. the monarch selected to preside over the functions of human life was the liver; and it is only with bated breath that any doctor dares question the legitimacy of that monarch's claim. the loyal subjects of king liver are ever ready to call out "quack," "charlatan," etc., to those who dare repudiate the sovereignty of the liver. so much attention and flirtation does the liver receive from the _liver-persuaders_ that the pancreas ought to be very jealous. the pancreas excretes quite as much fluid into the duodenum as its larger neighbor, and is, therefore, no mean organ. and we need not wonder should we find the intestinal glands piqued at our over-attention to the liver, as they, in their work at the metamorphosis of digested food into blood, excrete two or three gallons of fluid in a day to the liver's two or three pints; yet witness our medieval solicitude for the liver, for one among many organs. the liver is located near the upper portion of the intestinal canal and connected by a tube (the bile duct) to the rest of the excursion route. the following liver-persuading knights-errant are prescribed and ordered by disciples of hippocrates, galen, herodicus, and iccus, to treat with that digestive and eliminative monarch, the liver--usually at night-time, that the family may not be disturbed. after making as good terms as possible they journey on, riotously churning and swashing the long, tortuous canal and its contents in search of ancient toxic gases and feces lodged in the lower bowel. it is believed by the prescribers that the length of the journey adds dignity to the drastic, dredging knights-errant. the reader needs no introduction to the podophyllins, the aloes, the jalaps, the rhubarbs, the mercurys, the croton oils, the sennas, the salines, the seltzers, the carters, the beechams, the websters, the pierces, the ayers, the ripans, the warners, and others belonging to "the four hundred" fashionable grenadiers, with their credentials and stamp! after these knights-errant have paid their respects to king liver, and ended their long, tortuous and eventful journey, they depart and leave behind them burning and painful abdominal and anal regrets, and then some soothing, stimulating and tonic remedies are in order, so that the dredged though chronically constipated sufferer and his friends may still hope that life will be spared to repeat the same nauseating and often painful process in a few days or weeks, taking, in the meanwhile, milder bile-bouncers daily as a reminder to king liver that the time for the knights-errant is coming again. sufferers from chronic constipation receive assurances that by the use of these "remedies" the anemia will be corrected, nutrition and digestion restored, atony of the liver and intestines overcome, yellow complexion and morbid feeling disappear. in short, remove the numerous symptoms and "causes" of toxicity of the body and of chronic constipation, and proclaim the victory of powder and pill! all of us would believe medicus, the son who so abjectly follows in the footsteps of his father, if we could really feel the possibility of such a victory; but the protests of our bowels are living witnesses against the validity of the medieval practice as here described; and we ask for a modern scientific solution of the fulness and foulness within and the fatuity without. i must now apologize to the large class of sufferers from chronic constipation for hurting their feelings. i know very well how seriously they have been compelled to regard their trouble, and out of respect for their protracted suffering and efforts to get relief i should instead have sympathized and condoled with them in their dire misfortune. but we all know and realize that there are occasions when we get into awful and painful predicaments, and, when the whole situation is taken in, it becomes comical and ridiculous, so that for a time we cannot treat it seriously, even when old chronic biliousness and the mighty knights-errant are having a deadly combat at our internal and external (and possibly infernal) expense. chapter xii. semi-constipation and its dangers. "at least six times in every fleeting day some tribute to the renal functions pay, and twice or thrice all alvine calls obey." what has been said thus far has been based on chronic constipation mainly, and the accompanying intestinal foulness, which condition was shown to be so annoying that it compelled the sufferer to resort frequently to some more or less direct and artificial means for the relief of the bowels and the incidental indigestion. it has been further shown that many of the chronic cases fail to take on the normal amount of flesh or lose what flesh they have because of self-poisoning (auto-infection), which in turn is the outcome of mal-assimilation and mal-nutrition, and that this consequence must occur wherever there is an absorption of waste through a checking or disturbance of systemic functions. emaciation and anemia are inevitable in such cases. on the other hand, there are cases that have such great powers of assimilation and elimination that they are able to stand the invasion of destructive material, may maintain the normal amount of flesh, or even take on an abnormal amount, but with the invariable accompaniment of more or less impoverishment of blood, disturbed circulation, indigestion, and the usual nervous derangements. the harmful practice of the lean and the fleshy sufferers of resorting to daily medicines--cathartics, digestives and tonics--has been commented upon. willingly do they squander their money to get relief from an ever-present ailment. cases are these of hope deferred that maketh the heart sick. the primary cause of chronic constipation, namely, proctitis, has been explained, and its many symptoms, as indicated by the functional disturbances of many or all of the organs of the body, enumerated. but beside the cases of chronic constipation--both lean and fat--there are many sufferers from auto-infection who have only semi-constipation, or partial evacuation of the feces daily. though they suffer from the effects of self-poisoning, yet they have no such well-defined symptoms of local disease and functional disturbance as are always found in those who have chronic constipation. nevertheless, they have disturbances of practically all the functions of the system. believing as they do that the evacuation of their bowels is complete, they are at a loss to find a cause for the toxemia (blood-poisoning), mal-nutrition, debility and general atony. the symptoms of auto-infection with the semi-constipated are as complex as with the severer cases, but not so well defined. the most prominent symptoms are those connected with the process of katabolism, that is, of degeneration of the tissues, as indicated by their color and texture. the liver, however, is usually held responsible for the bad complexion, impaired nutrition, constipation and diminished vitality, when really the liver is only indirectly concerned, as made manifest in the previous articles. the seat and source are found to be the diseased colon and rectum. dr. treves says: "the colon being the part of the bowel involved in obstruction due to fecal accumulation, it may be further assumed that the blocking of the gut will most usually concern its lower or terminal parts. accumulation of feces is most common in the rectum and sigmoid flexure, and then in the cecum. masses of feces may block the colon at any point, and more particularly at the flexures of the bowel. still, the three common sites of the accumulation are those just named. the accumulation in the colon may assume the form of a more or less isolated nodule or mass. thus a considerable lump may be found in the cecum or sigmoid flexure and the rest of the colon be comparatively clear of any gross accumulation. an isolated lump may even persist after free purgation. on the other hand, the accumulation may assume the form of several isolated fecal masses. one of them may occupy the cecum, another the transverse colon, and possibly a third the sigmoid flexure. the bowel between these masses may appear to be fairly clear." a number of the exciting causes of inflammation of the lower or terminal portion of the large intestine have been mentioned. it cannot, however, be too strongly emphasized that chronic inflammation of the colon and rectum results in hyperkinesis (excessive muscular irritability) and contraction of the diseased portion invaded, thereby retarding or preventing the passage of feces and gases. a portion of the daily accumulation of feces in the sigmoid may pass through the diseased rectum every day, but not without increasing the inflammation and the spasmodic contraction; this in time inhibits the elimination of the accumulating feces, which by undue retention become condensed and hardened. each day will then be a repetition of the abnormal and partial effort of the organ to accomplish the act of defecation, and there will be no thought of the cumulative and chronic intoxication (poisoning) of the system from the imprisoned feces and gases. it may be stated without reservation that the rectal canal cannot be involved in chronic inflammation without involving the anal canal, and _vice versa_. one half of civilized people are suffering from chronic constipation, and very nearly the remainder from semi-constipation. the semi-constipated are now under consideration. the chronic cases are those that have a _complete_ impaction of feces in the terminal portion of the sigmoid and rectum; the semi-constipated have the usual daily _partial_ impaction, that is, an incomplete or partially successful evacuation of the contents of the bowels: the incompleteness is due to disease of the anal and rectal canals. the anal and rectal canals are made up of circular and longitudinal muscular bands, which, when invaded by disease, lose their proper or normal sensibility and coã¶perative voluntary action. the excessive contraction of the circular muscles closes the calibre or bore of the gut, and the excessive contraction of the longitudinal muscles shortens the length of the gut, thus throwing the mucous membrane into abnormal folds which increase the depth of the sacculi, or cavities, between the fibrous folds. in the normal gut the sacculi and bands act as valves to control the descent of the feces. this valvular arrangement and the curvatures of the lower bowels conserve the energy of the involuntary and voluntary nerve force until there is a sufficient accumulation of feces to excite a normal desire for stool; otherwise the feces would rush upon the anus at once and occasion much inconvenience. catarrhal inflammation of the mucous membrane of the anal canal will sooner or later penetrate the muscular structure of that canal, causing an abnormal irritability and contraction of the sphincter ani and the other tissues composing its structure. the contraction of the anal tissues becomes more permanent as the muscular tissues of the structure become cohered or bound together by the process of inflammation. the normal stimulus and sensation that should precede the act of defecation are perverted or destroyed by the excessively irritable contraction of the sphincter ani, which contraction is occasioned by the presence of feces and gases just above the seat of inflammation, that is, above the anal canal or at the lower end of the rectum. as the bulk of feces and gases lodged at this point increases, the anal contraction becomes firmer in grip, and as a consequence permits no hint of the imprisoned contents until the accumulating bulk is beyond the power of toleration by the organ. daily a portion of the lodged feces, or some new addition to the mass, passes the anal canal, but the attending irritation or contraction of the muscles prevents any further exit of the imprisoned rectal contents. chapter xiii. the etiology of the most common form of diarrhea, i.e., excessive intestinal peristalsis. if you are interested to know why a certain plant does not flourish in the temperature and light to which it has been accustomed, you investigate the soil--the source of nourishment--and thus determine why the downy or velvety appearance has left the flower; why the leaves are yellow, dry or falling; why the stems are withering. even the most ignorant person knows that the symptoms the plant presents did not bring about the unsuitableness of the soil; that, on the contrary, the condition of the soil is responsible for the plant's present state. would it not be unwisdom, therefore, to treat directly the symptoms of decay, instead of treating the soil, or changing it? just so misguided is the judgment of the physician who prescribes physic or tonics in the case of a person having a foul intestinal canal, a condition destructive of the absorbent and the excretory glands. but members of county medical societies do just such foolish things. notwithstanding their prescriptions, a point will be reached by the patient where the restoration of his millions of small rootlets, or organic feeders, will be impossible, and like a decaying plant in unfavorable soil he gradually decays or withers, here and there, until finally he topples over before he knows it, probably long before maturity has been reached. it is not generally known among laymen, nor sufficiently appreciated among physicians, that the mass of fecal matter normally evacuated from the bowels comes mainly from the blood; and that this mass is not, as it is usually supposed to be, the residue of the food that has been left unassimilated. embedded in the mucous membrane of the colon are tubular glands under the control of the nervous system. when these glands become unduly excited through local inflammation and irritation, the normal flow from them is increased to such an extent that a rapid waste of precious tissue occurs throughout the system, and the vital force--which had taken perhaps years to store--is depleted to the point of exhaustion, sometimes even in a few hours. almost every one has had some experience of exhaustion following diarrhea. the increased flow of blood to the mucous membrane of the colon furthers this extraordinary secretion by the glands. as has been pointed out, inflammation, septic poisoning, intestinal foulness, or retained feces, act as irritants on the mucous membranes, thereby drawing the blood to the colon where it is excreted and exhaustion follows. the great danger in diarrhea, therefore, is the rapid depletion of the vital force. but when the small intestines are affected the consequences may be still more deplorable. then the unassimilated food is hurried along too quickly for absorption and the body receives but little nourishment to restore its powers. thus another draught is made upon the sufferer's reservoir of vitality, and hence additional exhaustion. but this waste of tissue, loss of vital force, non-assimilation and non-supply, are not so grave as the positive danger of the permanent destruction of the millions of small absorbing vessels (villi) of the small intestine by a continuance of this abnormal irritation. of course the secretory and excretory glands of the colon also suffer, and we then have costiveness resulting from lack of absorption and excretion. abnormal irritability of the bowels is necessarily involved in the inflammatory process known as proctitis and colitis. increase this irritability to a certain point and diarrhea takes the place of constipation--a much more alarming symptom. diarrhea is more alarming because the intensified local activity of the excretory glands of the bowels brings on, as has been said, a general exhaustion of the vital powers. the severity of diarrheal symptoms is much increased by the character and abundance of bacterial poisons. bacteria find a ready medium in fetid feces, and are absorbed by the excited glands to the degree in which these glands have time and power for absorption. of course the extent and character of the intestinal irritation have a good deal to do with the severity of the diarrheal symptoms. this irritation is not infrequently intensified by a catarrhal process, or by a lesion of an ulcerative nature. all these forms of irritation bring on "excessive intestinal peristalsis"--which, accordingly, is our definition of diarrhea. the normal peristaltic action of the intestines propels the nutritive as well as the effete material through the canal at a rate that allows of both proper absorption and timely elimination. but when excessive peristalsis occurs, neither absorption nor elimination will be normal or suited to the requirements of the system. undigested foodstuffs may become an irritant, or increase, as is usually the case, the established irritation, and thus bring on an acute attack of diarrhea. the immediate consequence of the acute attack may indeed be, and often is, comparatively beneficial, inasmuch as the diarrhea removes the undigested material that occasioned the irritation. when this removal is accomplished, the diarrhea usually subsides without treatment. this is the case, however, only when the patient has committed an infrequent error in diet. when such errors are habitual the burden on the glands of the intestinal mucous membrane becomes intolerable, and the chronic inflammation once established has a tendency to proceed from bad to worse. it will then be observed that digestion becomes more and more impaired. in such a case diarrhea will no longer serve a good end, but will on the contrary debilitate the system. a change to better dietetic habits will then aid, but will not suffice for cure. only treatment and time will restore the inflamed parts to a healthy tone. when, however, the digestive tract is invaded by any of the many forms of bacteria, treatment will avail little and serious consequences follow rapidly. too much cannot be said or done to secure intestinal cleanliness in infancy, childhood and maturity. mothers and nurses cannot give this subject too much thought and care, since the welfare of future generations depends largely upon intestinal cleanliness, in view of the rich and racy life of our hothouse civilization. we are a people poisoned through constipation and diarrhea: two affections that derange more lives than all other pathological conditions together. banish alimentary uncleanliness and you take most of the poisons from the human race--poisons that stunt the body and blunt the mind. the soul of man should dwell in a palace, not in a pest-house; in a human temple, velvety, lined with down, inside and out; in which there are hundreds of millions of lilliputian trappings, fittings and articles of furniture, to carry on the minute and finer functions and chemistry of the soul. the very multitude of the fine equipments that decorate the temple give it that beautiful blending of color and form which its coating has when in normal condition. they adorn this body-house with health, and supply it with the rich red wine of joy. the blood is dependent for its richness not only on the digestive fluids, but also on the proper eliminating powers of the system. if you would avoid premature decay you must not neglect the reservoir of vitality, the alimentary canal, but see to it that it be kept clean and pure. then will the elixir of life spring from an almost inexhaustible fountain. to recur to our plant analogy. keep the soil in your own vegetable garden sweet, for intestinal cleanliness corresponds to soil fitness. purity of the stomach and bowels is more important than quantity or quality of food. that defecation should occur normally two or three times in twenty-four hours is more important than that three meals should be eaten within that time. the conveniences for eating and drinking are on every hand, but oh, how few, inaccessible, miserably constructed, and poorly cared for, are the toilet cabinets for the accommodation of the gourmand! suspenders and silk hats mark the progress of our outer refinement; toilet cabinets and flushing appliances, of our inner. when the _inner_ refinement comes we shall live longer and be healthier. chapter xiv. ballooning of the rectum. to make plainer what has been said of the rectal and anal tubes or canals, consider the sleeve of an infant's gown. this sleeve well represents the rectal tube, the wrist-band the anal orifice and tube--an inch or more long. think of the sleeve or rectal tube as being made up of four layers of material or membranes; and counting from the inside of the sleeve or rectum there are (1) the mucous layer; (2) the areolar layer; (3) the muscular layer; (4) the serous layer. the muscular membrane is itself composed of two layers, and may be said to form the framework of the rectum. one layer is composed of circular muscular fibres, and the other of longitudinal muscular fibres. in a similar manner you could make a sleeve out of fine circular rubber bands; then bind them together by rubber strings extending lengthwise of the sleeve. with the circular bands the bore of the sleeve may be contracted or widened; and with the longitudinal bands the length may be shortened or extended. just so with the corresponding muscular membranes of the rectum, in their normal and abnormal conditions. outside of the longitudinal muscular bands are the serous and areolar layers, the latter covering the lower half of the rectum. as you look inside the incomplete model of the rectum, or rather sleeve, you observe circular muscular bands or fibres which it is necessary to cover with soft spongy or fatty substance in whose meshes are nerves, blood-vessels, etc. this is called the areolar layer or coat. one more layer or coat upon this--the mucous coat--completes the structure. this latter possesses the power of accommodating itself to the distention and contraction of the muscular tube. the mucous membrane is thrown into folds and columns which serve as valves to inhibit the undue descent of the feces, thus assisting the mucous membrane in performing its office. the length of the rectum varies in different persons, six inches is the average length. it is divided into two parts. the upper part is a little more than three inches long; beginning in front of the third sacral vertebra and extending down to the end or tip of the coccyx. in shape this part conforms to the curve of the sacrum and the coccyx, to which it is attached behind. the lower part of the rectum is a little shorter than the upper part, and begins at the tip of the coccyx and extends down with the same curve as the upper part, terminating at the upper portion of the anal canal. returning to the sleeve again; the portion of it from the shoulder to the elbow illustrates the upper part of the rectum when partially covered with a serous coat on the side opposite the bore (the outside). from the elbow to the wrist-band illustrates the lower part of the rectum, when covered on the outside with an areolar coat. the wrist-band of the sleeve will represent the anal tube if drawn into a pucker and turned slightly backward from the direction of the sleeve of which it is a continuation. the muscular fibres described above likewise enter into the formation of the anal canal or orifice. this orifice is closed by two strong muscles that lie close together and are called internal and external sphincters, which are abundantly supplied with nerves and blood-vessels whose branches extend to the neighboring organs. nine persons in every ten have more or less chronic inflammation of the mucous membrane of the anus and rectum. in time the areolar and muscular coats become invaded by the morbid process, and this increases the irritability of the tissues of the organ. the change from the normal functions of the anal membranes is slow, and the symptoms are not well marked and are consequently ignored for years owing to inexpertness in detecting an invading serious disease, until the time comes when the suffering can no longer be tolerated by the victim of the neglect. the result of disease to muscular tissue is contraction of its fibres, and the contractions become more painful as the disease increases. accompanying the inflammation, there is a more or less inflammatory product secreted between muscular fibres that "glues" them together in their contracted state. and as the anal and rectal tubes are made up of round muscular fibres, it is not hard to see how the bore of the canal can be lessened by the slow binding together of its fibres in the contracted state. the fact is that when the anal structure is invaded by inflammation, there is more or less stricture of the canal and of the orifice. recalling the sleeve illustration, and how the wrist-band was puckered and bent back a trifle so that the contents of the sleeve would not pass out so easily, suppose you now pucker the wrist-band rather tightly, and suppose there is a forcible descent of sand in the sleeve, the natural result would be a bulging out of the lower portion of the sleeve just above the wrist-band, or place of undue constriction. if the abnormally constricted condition of the anal orifice has been growing from bad to worse for years, the locality immediately above the anal canal will become dilated or cavernous (caused by retained feces or gases), which cavity is called ballooning of the rectum. when a speculum is introduced into the rectum (as shown on page 14 of pamphlet _how to become strong_), and through it a bent probe is inserted to determine the depth of the dilatation or abnormal cavity, it is as if one were poking inside of an inflated balloon: hence the name. anatomists describe the rectum as terminating in a forward pouch, which is close to the prostate gland in the male and the lower part of the vagina in the female. in some cases there may be such a slight pouch, due to the anal canal not following the direction of the rectum, and slightly turning backward; but in most cases such a normal pouch is not perceptible or observed through the speculum. the small pouch sometimes found on the anterior wall of the rectum i have thought due to a very acute inflammation on the verge of forming abscess, which often occurs in the triangular space. (see 4 in diagram in pamphlet cited above.) immediately above the sphincter muscles on the posterior wall of the rectum the greatest dilatation is found (as shown by the bent probe), and extends on each side with less depth about the anterior wall of the rectum. the greater portion of the lower part of the rectum, which part is about three inches long, is usually involved in the dilatation or ballooning. often the upper half or more of the anal canal is also dilated with the rectum, leaving the sphincter muscles quite bare of fatty tissue, with anal length of a quarter of an inch or less. your attention was called to a sleeve containing sand, and the bulging or dilatation above the puckered wrist-band that was an inch or more broad. now suppose there were two strong rubber rings at the lower end of the wrist-band, whose power of resistance to pressure is much greater than the tissues above them forming the wrist-band. naturally, the tissues which form the upper part of the wrist-band would dilate the same as the terminal portion of the sleeve just above the wrist-band. similar changes in structure or formation take place in diseases of the anal and rectal canals which result in ballooning of the rectum; and two frail constricted sphincter muscles are left to guard this balloon, filled, as it so often is, with feces and gas. chronic inflammation, that results in contraction of the circular muscular fibres, will sooner or later constrict the gut so that it will lose its normal power to expand without causing pain. the anal canal may be said to be strictured to the degree in which it is unable to dilate normally, and this strictured condition usually grows from bad to worse. the first symptom of rectal disease is usually an affection of the anus, which affection occasions an inhibition, that is, a reluctant permission for the passage of the feces; and this inhibition results, consequently, in some degree of constipation. and this constipation reacts more or less on the peristaltic action of the bowels and in time defeats the function of peristalsis. all this will react on the inflammatory processes at the anus, which originally engendered the constipation. the narrow and contracted strait or canal through which the feces must pass, gives a tape-like shape to the stools. the anal and rectal mucous membrane is of a firm and tough structure, similar to the integument at the bottom of a boy's heel. after many years' observation of diseases of the anus and rectum i am forced to conclude that as a rule inflammation exists in the tissues twenty or more years before the severe symptoms, such as piles, fissure, anal pockets, pruritus, hypertrophy, atrophy, tabs, abscesses, and fistula, are sufficiently annoying to compel the sufferer to seek medical aid. i believe it to be of as much importance to give early attention to disease of the anus and rectum as to teeth and eyes, or even more. chapter xv. ballooning of the rectum--continued. in the last chapter a description was given of the anatomy of the anus and rectum; and it was shown how a chronic inflammatory process involving these organs develops stricture in the parts invaded; and it was shown how a partial stricture of the anal canal results in ballooning or dilatation of the lower part of the rectum. the primary cause of all the symptoms of rectal disease is chronic inflammation (proctitis) involving the whole structure of the anal tubes and in a few cases the sigmoid flexure as well. perhaps the first marked symptom of disease of the rectum is constipation, semi-constipation or of chronic character. the function of the anus and rectum being disturbed by the inflammation, the fecal mass is unduly retained and its moisture is absorbed by the system. this accounts for the condensed and hardened fecal mass in isolated lumps of various proportions. a hard-formed stool is abnormal, and is evidence of auto-infection. when three-fourths of the normal fecal mass has been re-absorbed by the system, does it not stand to reason that the blood and tissues have been poisoned by their own waste products (auto-intoxication) and that anemia, emaciation and local disturbances of other organs of the body are symptoms of such intoxication? the loading and blocking of the sigmoid flexure come from _too much activity or irritability, due to inflammation, of the upper half of the rectal tube_. a consequence of this excessive sensitiveness is a diminished or perverted normal stimulus, notice or desire, that the act of defecation should take place. the victim of proctitis simply forms a habit of daily soliciting an evacuation, though the normal invitation or desire to stool may be entirely absent, and the evacuation in such cases is attended with more or less delay and straining effort to accomplish partially or wholly the expulsion of the more or less inspissated feces. as the extreme sensitiveness of the inflamed upper half of the rectum offers resistance to the passage of the fecal contents of the sigmoid flexure; so, in a somewhat similar manner, the inflamed anal tube, in its more or less constricted state, prevents the passage of feces and gases as they approach the terminal part of the rectum. as a consequence, the feces and gas deposit and lodge at this latter location, producing in so doing the abnormal cavity called ballooning of the rectum, so often found just above the anal tube. the greatest depth of the dilated pouch is on the posterior wall of the rectum, or just in front of the tip of the coccyx. in some cases the pouch measures two and a half inches in depth at the back and gradually diminishes in depth on each side as you near the anterior wall of the rectum. often the upper end of the anal canal is higher than the depressed circumference of the spacious cavity that almost surrounds it. the irritable orifice of the cavity will invariably compel a quantity of liquids and feces to lodge in the cavity as a permanent cesspool, allowing the absorbent vessels to absorb as much as they can by incessant work. the height or length of this abnormal cone-shaped rectal cavity is from two to three inches, involving usually the lower half of the rectum. the anal canal frequently becomes shortened by the dilating process to a quarter of an inch, leaving two frail, irritable muscles at the vent, to guard the rectal cavity. and fortunate are these two thin, sore, contracted muscles, and the possessor of them, if they escape the surgeon's barbarous notion of operating on them. if the medical butcher has operated on them, you will find an anal canal open to such an extent that two fingers can be inserted without distending the tissues in the least. and when the victim of ballooning of the rectum and ignorant operation makes further complaint to the surgeon of the aches and pains, he is consoled by being informed that the end of the spine will have to be removed. irreparable damage done and no aid at all received! it is a pity such ignorance on the subject should exist in the medical profession in this city. the abnormal cavity, so difficult to empty properly owing to its depth and diseased outlet, is seldom free from gases, feces and liquids. daily evacuations will not empty this cavity, nor will cathartics or diarrhea. a permanent cesspool of poisons is this, where all forms of poisonous germs are propagated, and infect the system by absorption. no use to take medicines for your _poor blood, bad complexion and horrid feelings_, as they will not cleanse the augean stable so long neglected. no use to journey to other localities for health so long as you carry so formidable a foe to health with you. the mucous membrane in the chronic state of the disease presents a rather dry, indolent and bluish appearance, except that here and there the tissues show more activity of the disease, more especially so over the anal region, due to harsher disturbance during the act of stooling. in the subacute or acute stage of the inflammatory process there is more general redness and puffiness of the mucous membrane, or a swollen condition with increased discharge of mucus and perhaps some blood. there is a heavy, uncomfortable feeling, with more or less soreness and pain, especially after evacuation of the feces. if a fissure or anal ulcer is present the pain is in proportion to its size and the general aggravation of all the diseased parts. itching or pruritus about the anus may accompany the trouble to a very annoying extent, being an evidence that the anal pockets are becoming much diseased. the partially constricted and irritable sphincter muscles become excited during the act of stooling and react on the anal grip or contraction, making it more intense. this latter condition may shut off the flow of blood in a local vein; and the blood becoming coagulated forms a painful bluish grape-like tumor at the external opening of the anus. abscesses may form at some portion of the diseased gut and result in an external fistula. piles may co-exist in some cases of ballooning, but are usually not annoying. it is the local anal or external annoyances that compel the sufferer to seek medical advice and aid, and he learns that the troubles complained of are only symptoms of a chronic disease, therefore easily removed without harsh treatment while the cause is being properly cured. it is very fortunate for the sufferer from ballooning of the rectum to have in or near the anal canal those painful hints or symptoms of a very grave and long existing disease whose constitutional symptoms were well marked but attributed to other causes, especially to disease of the liver--an organ of _so much solicitude_ that the poor liver-worshipping patient ought to receive more gracious response from it. in every case of chronic proctitis, or inflammation of the anus and rectum, the sigmoid flexure must be more or less dilated, as the upper part of the rectum is very irritable and contracted and inhibits the feces from passing beyond the sigmoid; but this irritability and contraction of the rectum, as a rule, is not nearly so severe as that of the anal canal, whose orifice is closed by very strong sphincter muscles. such being the pathological change in the sigmoid flexure and especially in the lower portion of the rectum, as described in these two chapters, who, with ordinary intelligence and an idea of cleanliness, would take or prescribe remedies to move the bowels, if it were possible to cleanse the foul capacious cavities with water? we know that they can be thus cleansed, and that it can be easily accomplished with benefit to the diseased canals. after the system has absorbed 75 per cent of the fecal mass, a "remedy" is taken to excite a flow of watery excretions into the bowels, of which a portion will be retained in the colon, and especially the ballooned cavities, and reabsorbed; and every day the objectionable practice is repeated without any thought of the harm being done. the flushing of the rectum, sigmoid flexure and colon with water is not a _cure-all_, but it is one of the means of treating a grave chronic disease, a disease insidious and far-reaching in its poisonous effects on the human organism. chapter xvi. the usual diagnosis and treatment of bowel troubles wrong. herodotus tells us that among certain tribes when a man fell sick his next-door neighbor did not wait for him to become thin but killed him at once, lest by the loss of his adipose his flesh might be rendered less appetizing. but alas! in this age of constipation and piles, of self-generated poisons and self-infection, how changed is the custom! our next-door neighbor, the doctor, waits till we are really thin, and then begins to feed and grow fat on our ills! in our day, through the continuous process of self-poisoning we take on no flesh from puny, peaked childhood, or we insidiously lose what little flesh we had, and when our bones are well exposed, become alarmed, realize that we are sick, rush for the doctor, and dispossess ourselves of our spare cash. very frequently, as stated in the first chapter, auto-infection begins in infancy and slowly but steadily progresses, but it may not be before adult age is reached and one or more organs are seriously diseased that it becomes apparent to all. the vital round of the alternate building-up and breaking-down of the system has been going on unceasingly during these years of increasing infection, but prematurely the balance between up and down is lost in favor of down; the building-up process becoming feebler, slower, and the breaking-down process quicker, easier. what can the inevitable outcome be but _emaciation_ and _anemia_, and all their attendant suffering and consequences? it is the superabundance of vitality in the growing child that retards (inhibits) the morbid changes going on in the blood and tissues of the system; but the process is all the more insidious by being thus restrained, and its very subtlety and stealth beguile us all into fancied security: parents, friends, physicians--all are deceived. as stated in a previous chapter, the first unwelcome visitor, in infancy, is inflammation of the integument and mucous membrane of the anal orifice, invited by the uncleanliness involved in the use of diapers; and this visitor takes up its residence slowly along several inches of the lower bowel. its first symptoms are likely to be constipation, flatulency, colic, indigestion, bacterial and other poisons, occasionally diarrhea, and the usual general disturbance of the system as above detailed. it is admitted by all authors that inflammation of the anus, rectum, etc., is by far the most common disease that afflicts mankind at all ages; and i maintain that the natural result of such inflammation is a more or less extensive occlusion of the lower bowel, which in turn involves an undue retention of the feces, and thus we have the foul intestinal canal and stomach called gastric and intestinal indigestion. the wrong treatment of constipation, diarrhea, indigestion and auto-intoxication up to the present time has been due to improper diagnosis. writers on these subjects speak of them as causes when they are merely symptoms. and the remedies for these "causes" are even more numerous. _mistaken diagnosis on the one hand, measured doses on the other, and there you have the scientific doctor!_ the primary cause, inflammation, like the original spark applied to dry shavings, sets up morbid changes in the various parts of the digestive canal and the other organs of the body, and these "set up" or established changes are properly secondary or derivative causes accompanied by their own symptoms. the primary disease and symptoms may exist for five, ten, twenty or more years before any pronounced secondary or derivative diseases and their symptoms occur or are noticeable to a sufficiently marked degree. the chronic character of the malady, and the complication of primary with secondary diseases and their symptoms, have thoroughly disconcerted the doctors. hence the many "causes" assigned for indigestion, constipation, etc., and the many kinds of remedies prescribed with the one sure result, failure; and hence, also, not a few of the selfand drug-intoxicated ones dubbed, or actually developed into, hypochondriacs. diagnosis wrong, treatment wrong, failure certain, and the foulness of the intestinal canal continued! this is the experience and testimony of the many, many sufferers from the most common malady that afflicts humanity from infancy to old age, and which will continue to afflict the great majority until it is properly understood and treated. when a sewer of a town is obstructed, the most sensible plan is to begin the investigation at the outlet and then proceed up, section after section, to trace the obstacle that had occasioned the accumulation of debris. when the waste-pipes of a house are clogged, we do not expect the plumber to go to the top of the building and poke substances down the pipe to dislodge the unduly retained material some twenty-five feet or more away. nor would we believe him if he informed us that the sewer-gas and overflow of waste in the house were the _cause_ of the constipated condition of the drain. but just this is what the doctor declares concerning our sewer; just this is what he does when he doses it with laxatives, cathartics, purgatives. such is the treatment we receive when we rush to the doctor, or such the treatment we give ourselves. the poor, sensitive, inflamed canal is desecrated on all hands, though part of a house not made with hands--a house that should be a home for the soul of man. chapter xvii. costiveness. the words constipation, obstipation and costiveness are often employed as if of exactly similar meaning, but it is well to let each stand for a particular condition. obstipation implies that the canal of the intestine is stopped up or closed. constipation carries the idea that the canal is completely filled up with refuse matter. in the normal condition the intestine is divided by transverse bulges or valves or dams into a number of separate segments, the entire arrangement having the effect of preventing too rapid descent of the feces. these folds within the canal may become too much narrowed by disease and thus prevent the movement of the matters inside; this is obstipation. constipation, stuffing of the gut, may be the result of neglecting the call of nature, and after a time the ability to recognize and answer it is lost; or it may result from inflammation which itself comes from the bad habit mentioned. the author prefers to use the term costiveness for the general debased condition of the system from auto-intoxication depending upon proctitis and similar conditions of the intestinal tract. and it must be remembered that the same patient may have two or more of these conditions at the same time. constipation, obstipation and diarrhea may alternate through the progress of the case. we would expect people suffering from constipation or obstipation to pass as fairly well people for a time, but the same is not true of patients having the other condition, costiveness. as we may speak of the stages of a disease like consumption, so we may speak of these three conditions as different stages of one affliction, the worst being costiveness with its progressive self-poisoning by the products of intestinal decomposition. early in the case the system may pass these poisons out of the body with comparative ease, by way of the lungs, skin and kidneys. in time the second stage begins to make itself apparent, vitality becomes less and less, calling for a greater variety of medicines to correct the condition, as in the second stage of consumption, and also to arrest the progress of emaciation and anemia or anemic obesity. the third stage of auto-intoxication is a most unhappy one. the impoverished tissues offer a most favorable soil for the development of diseased conditions. these three stages which are clear to the experienced eye of the physician may to the patient seem to be indistinguishable, the one from the other; and it must not be forgotten that the three conditions do not mean simply that a smaller or larger part of the intestine is clogged by its contents, but that the whole system is involved as well. it cannot indeed be otherwise with the rapid circulation of the blood, nor need it excite wonder that such patients are thin and debilitated by the deadening of the powers of absorption, assimilation and elimination. as a rule the many thin and puny infants and children of either sex, with bony points well exposed under a tightly drawn skin, which latter is clay-colored and pimply; children with headache and languor, without healthy interest in either studies or play;--these are the victims of intestinal poisoning as described. if they have inherited a spare habit of body from their parents such bodily ills will manifest themselves the more quickly. they ought to be fat and hearty as are the young of animals, but alas many are not! when the young animal is spare, a few days of rest with good diet will put flesh on it, demonstrating that the state of the bowels and the powers of assimilation are intact. why does not man take on flesh in a similar way? if the intelligent animals could talk, they would undoubtedly make all manner of fun of the intestinal canals which they see walking about, with a little flesh here and there seemingly by accident, and a skin which is clay-colored or jaundiced, anemic or flabby, the owner of it all poisoning himself by decomposition in his intestines! chapter xviii. inflammation. if we desire to get a general idea of the changes that occur in an organ when it becomes inflamed, we must first have a knowledge of the normal structure of that organ, even though that knowledge be but superficial. taking the intestines, for example, we see under the microscope that they are composed of layers of different tissues, called connective, epithelial, muscle, and nerve tissue; the first two forming a large part of the structure. in the connective (and fatty) tissues a great many blood-vessels are found (varying in different parts of the organ), the existence of which is necessary for the production of inflammation, since at the very outset of the process, a discharge (or exudation) takes place from these blood-vessels, accompanied by changes or degenerations in the other kinds of tissue. the process of inflammation is commonly associated with symptoms of heat, redness, swelling and pain, in greater or less degree, combined with which a change in the function of the organ is soon noticed. micro-organisms are considered the primary cause of inflammation in many or even in most cases in which mechanical or chemical influences may undoubtedly be responsible primarily; and then again, each of these causes may be either external--that is, may originate from the outside world--or internal, that is, may be produced in and by the body itself. the first pronounced change occurring in an organ under inflammation is an increase in the rapidity with which the blood circulates through the vessels--a so-called hyperemia--which soon gives place to a diminution (stasis) in the current together with an exudation from the blood-vessels; the latter is due to changes in the structure of their walls. this exudation soon occasions a cloudiness of the connective tissues and at the same time a desquamation (shedding in scales) of the epithelia (cells of the thin mucous surface). an irritation of the nerves also takes place. the varieties of inflammation can be best apprehended by considering the different characters of the exudation. the exudation may be watery (called serous) or dense, the latter either fibrinous or albuminous. with a serous exudation there is swelling of the connective tissue and a desquamation of epithelia--the latter usually slight in character--which constitutes what is known as a catarrh; while with a fibrinous or albuminous exudation there is usually more or less destruction of the tissue itself, when, for example, we have "croup" or "diphtheria." when the changes in the epithelia are only slight and secondary, it is spoken of as an interstitial (lying between) inflammation, which strictly speaking denotes confined to connective tissue, and is therefore a term not entirely correct. when the inflammation of the epithelia is severe and may lead to their partial destruction, it is called a parenchymatous inflammation; that is, one involving the soft cellular substance. there is still another variety, the suppurative, which is the most intense of all, and indicates the production of an abscess and the entire destruction of the tissue implicated. beside these general grades of inflammation there are special sorts produced by specific micro-organisms. in all general inflammation we may expect to find such organisms, which in most cases belong to the class of micrococci, such as staphylococci and streptococci. in gonorrhea we have a special organism called the "gonococcus"; while in tuberculosis--a variety of inflammation in which the blood-vessels are completely destroyed and a change or degeneration called "cheesy" is produced, leading to the production of a tubercle--a rod-like bacillus is invariably found, the well-known and unfortunately too common tubercle bacillus. in syphilis--another special variety of inflammation--a specific micro-organism is also surely present, but of this microbe science has not as yet discovered the exact nature. the question of the origin of tumors or new growths is also an extremely important one; and it is undoubtedly true that many tumors arise where there was a previous inflammation, this being especially the case in tumors of the rectum. why such a growth should arise in some cases and not in others is as yet unknown, though microbes are held by many to play an important rã´le. when an inflammation has lasted for such a length of time that it has become chronic, a new tissue will sooner or later be produced in varying amount; and this newly formed fibrous connective tissue may entirely replace previous normal structures. through the exudation and consequent changes in the normal tissue a large amount of mucus is at first secreted, but this secretion becomes less and less marked the more the inflammation causes a desquamation of the epithelia. pronounced desquamation with new formation of connective tissue and no fresh exudation will, sooner or later, occasion dryness--this dryness being sometimes very pronounced. the longer the inflammation lasts, the severer it will be; and the greater the amount of tissue it attacks, the more will the normal tissue be destroyed and replaced by a new connective tissue. a partial destruction will cause shrinkage of the organ (so-called "cirrhosis"); while a complete destruction of certain parts will result in what is known as "atrophy" (a wasting away of normal tissue). in atrophy the blood-vessels as well as the original connective and epithelial tissue are destroyed; while the newly formed tissue leads to hypertrophy (excessive over-growth) of other portions of the organ. such a hypertrophy must not be confounded with an induration that may be present later, or even at the very commencement of an inflammation, due to modification of the blood-vessels and surrounding tissues. chronic inflammation, sooner or later, leads to secondary degenerations, that is, new products of the protoplasm, the most common of which is fatty degeneration. in this form fat granules and globules arise, which are at first minute, later on larger; these in certain organs, such as the liver, may become so pronounced as to entirely replace the original tissue. another degeneration--which, however, is found only in chronic systemic disturbances, such as tuberculosis or syphilis--is the waxy or amyloid degeneration, a peculiar chemical change the exact nature of which is unknown. various chemical changes are by no means uncommon. an important question is the decision as to the length of time an inflammation has lasted; and this at best can be determined only approximately and after long experience. the older the inflammation, the more the connective tissue has developed; this connective tissue is at first soft, but soon becomes more and more dense; the result being a varying degree of hardness of the organs. again, secondary degenerations are more pronounced in long-standing processes. in comparatively fresh cases blood-vessels are still more or less numerous and the tissue appears red, while in older cases these vessels become completely obliterated, and the tissues take on a white, glistening color, becoming harder and denser as the years advance. if a process has lasted twenty or thirty years, the changes to the eye and touch are practically the same as after forty or sixty years. the changes, as here described, will be the same upon any mucous membrane; and in the large intestine can be easily studied and are perfectly characteristic. rarely does an infant escape repeated attacks of inflammation of the integument of the anus and the mucous membrane of the anal canal. the inflamed integument is treated and healed, but no attention is given to the inflamed mucous membrane so that the inflammation in time becomes chronic, involving the rectum also. should the infant be so fortunate as to escape inflammation (proctitis) of these organs during the wearing of the diaper, there are numerous other exciting causes of inflammation which it will not be likely to escape, hence the almost universal symptom of constipation among civilized people; and hence later in life you hear the familiar expression, "i have a touch of the piles," and many other complaints of bowel ailments that are usually the outcome of that deplorable inflammation. i have endeavored to make clear the fact that inflammation destroys normal tissues and blood-vessels, and that the newly formed tissue is cicatricial in character, that is poor in cells and vessels, with a tendency to contraction which of course lessens the bore of the gut. when the hypertrophy or thickening is extensive the appearance of the mucous membrane suggests the addition of one or more thicknesses of a chamois skin added to the inner surface of the anal and rectal canals. the hypertrophied or newly formed tissue may be limited to the rectum, leaving the anal tissues comparatively exempt from the superabundant cicatricial formation; or the hypertrophy may involve, to quite a degree, only the anal tissues and the integument around the anal orifice. the added connective tissue about the anus forms the skin into tabs, or into a circle of elongated integument around the orifice, with a mucous lining. these hypertrophied tabs or folds, like pruritus ani, are symptoms of proctitis. proctitis (the inflammation of the anal and rectal canals) is the most common and serious disease that afflicts man. the system is not only poisoned by bacteria and filth through proctitis, but proctitis is also the cause of the many annoying and painful local symptoms, such as hypertrophy, piles, abscess, fistula, cancer, polypus, fissure, pruritus, etc. when the subject of proctitis is better understood by laymen they will see to it that the rectums of children receive an examination before the children are six years old, and thus obviate the necessity of dosing them with all sorts of medicine that follow improper diagnosis. chapter xix. proctitis and piles. piles (hemorrhoids) are not the result of either the normal or abnormal growth of the tissues of the anal and rectal mucous membrane. they are developed by the combination of pathological and physiological conditions: (1) chronic inflammation or proctitis; (2) stricture of the anal canal and lower portion of the rectum, which may be spasmodic, or more or less permanent, which stricture pinches or constricts the canal, thereby inhibiting the circulation of the blood; (3) the pressure or straining effort during the act of defecation, occasioned by the constricted canal, which effort brings on greater local congestion and constriction of the tissues. pile formations are a symptom of chronic proctitis of fifteen, twenty or more years duration. proctitis (inflammation of the anus or rectum) and periproctitis (inflammation of the connective tissue about the rectum) are by no means uncommon inflammatory processes. the mucous membrane like the skin is liable to injury or poisons and especially so at the orifices of the body. let inflammation set in: if it be not cured at once, it will invade the canal, especially a canal like the rectum; in which case it will establish itself throughout from six to ten inches of its length, sometimes taking in the sigmoid flexure and even the colon. just how long chronic inflammation confines itself to the mucous membrane before invading the areolar or lace-like connective tissue and the muscular tissue of the organ, i am unable to state. the first symptom or indication that all the tissues are involved in the inflammatory process will most naturally be constipation. you have observed that inflammation of a portion of the skin on the arm, trunk or leg does not disturb the muscular movements of the region involved, except when the muscles underneath the skin are affected also, as in the case of deep burns where the movements are very much disturbed by the irritability, soreness and contraction of the diseased muscles. there is also an adhesive product excreted from the inflamed tissue that binds the muscular fibres of an organ together, and you have contraction of the organ and its usefulness impaired. now, as this is precisely the pathological or diseased condition which chronic cases of proctitis and periproctitis present, you will readily understand how spasmodic and partial stricture or contraction occurs in the sore muscles (circular and longitudinal) of the anus and rectum. the length and the bore of the canal are diminished, and thus the circulation of the blood arrested by the pressure or gripping of the contracted muscles. this congestion of the blood brings about an anatomical change in the structure of the mucous membrane, which we call piles: a mere symptom of inflammation. medical authors have defined inflammation as follows: "(1) a series of changes constituting the local reaction to injury; (2) a series of changes that constitute the local attempt at repair of actual or referred injury of a part; (3) a series of local phenomena that are developed in consequence of primary lesion of the tissues and that tend to heal these lesions; (4) the method by which an organism attempts to render inert the noxious elements introduced from without or arising within it; (5) a disturbance of the mechanism of nutrition of an organ or tissue, affecting the structures concerned in its function." these effects or changes give rise to the five cardinal symptoms of inflammation: pain, heat, redness, swelling and impaired function (dolor, calor, rubor, tumor, functio lã¦sa). proctitis may exist many years before the pain and heat become noticeable or are complained of by the victim of this insidious disease, the bodily symptoms of which are well expressed before the local trouble demands attention and treatment. the sufferer from proctitis is unable to detect the change from a normal color of the mucous membrane (a light, muddy gray) to an extremely abnormal one (a fiery redness). the swelling or puffiness of the mucous membrane becomes more marked as repeated attacks of subacute and acute inflammation occur, from year to year, over a period of twenty or more years. during all this time impairment of the function and structure of the anal and rectal canals is incessantly going on. the nervous and muscular spasmodic contraction of the diseased anus and rectum, which in time become more or less permanently constricted, steadily increases the stagnation and engorgement of blood in the dilated arteries, veins, arterioles, venous rootlets and capillaries. all of the circulatory vessels, especially the smaller ones, become enlarged, varicose; and an aggregation of varicosed vessels forms a tumor called a pile or hemorrhoid. inflammation interferes with nutrition of the anal and rectal tissues, rendering them friable or weak and easily broken; whence the bleeding and painful fissure or the anal ulcer, which so often are the outcome of proctitis and an accompaniment of piles. as already stated, piles are one of the symptoms of proctitis, and all cases of piles involve more or less irritability and contraction of the anal canal and the terminal portion of the rectum through which the fecal matter is forced. all the muscular ability of the rectum, assisted by straining effort of the abdominal muscles, is concentrated upon the feces to force it through the constricted portion of the lower bowel. the force exerted not only develops pile tumors, but carries out with the feces those tumors that had reached considerable proportions; thus the frail diseased mucous membrane is torn, and another symptom added to a chronic disease. observation for over twenty years has convinced me that chronic proctitis usually exists fifteen, twenty or more years before piles are developed (if developed at all), from daily pressure on the inflamed, congested, dilated, varicose, friable blood-vessels and surrounding tissue. piles are easily and quickly cured without any annoyance to the sufferer. chronic proctitis may be cured, but not quickly, as time is required to undo damage to tissues so long invaded by inflammatory process. any one that allows a continuance of "a touch of the piles," as the expression is, and omits to take proper treatment as soon as this "touch" is felt, simply invites or takes chances of some form of cancer of the lower bowel later in life. all other forms of disease of the lower bowel will yield to treatment satisfactory to physician and patient, but i am sorry to say cancer cases are numerous, and up to the present time we have no cure for this dreadful disease. if you value health, if you desire to avoid future suffering and disease, be sure that the lower bowel is free from inflammation, for with such freedom you will escape the many symptoms of proctitis described in my treatise on diseases of the anus and rectum. chapter xx. pruritus or itching of the anus. one of the many symptoms of proctitis is the existence of anal channels from which an inflammatory product exudes through the skin, causing painful itching of the skin around the anal margin and not infrequently around the buttocks to the distance of three, six or even more inches from the anal orifice. an aggravated form of pruritus ani is much more trying to physical endurance than severe pain. sometimes the torture is so great that a portion of the body will be covered with cold perspiration. the natural color of the integument about the anus slowly changes to a dull whitish appearance. as the pathological process goes on, the skin becomes thickened and parchment-like. in exceptional cases the mucous membrane of the anal canal becomes toughened and hardened like cardboard. as a consequence there is a degree of inertia in the muscular action of the parts affected. the inflamed, thickened and indurated integument near the anus takes on the form of folds, wrinkles or rugã¦, of more or less prominence; but as these extend out over the buttocks they become more and more obliterated, leaving no clue to the direction of the channel which leads from the site of inflammation; which latter, however, may be learned from the itching, or from the burning sensation with some soreness, over portions of their length. during a practice extending over twenty years, i have found only two cases in which one of these channels was the seat of a slight abscess. it is not usual that pus formations occur in these inflammatory channels. at the margin of the opening from the rectum to the anal tube are five or six small crescent-shaped loops, semi-lunar valves, separated by vertical ridges (the anal columns). naturally in chronic proctitis the zone of tissue just above the sphincter muscles and slightly within their grasp at the upper portion of the anal tube, would suffer greatly from the morbid process, owing to the abnormal constriction of the tissues and to the incidental pressure and injury, from time to time, as the stool passes the diseased region. just under the mucous membrane covering the anal columns and semilunar valves is the fatty tissue forming a bed upon which the mucous membrane rests. it is sufficiently lax to permit considerable movement of the mucous membrane on the muscular coat beneath it. the frail, fatty, loose connective tissue in the grasp of the sphincter muscles would be the first to become impaired by inflammatory process, the product of which finds its way down and out under the mucous membrane of the anal canal and integument of the buttocks for quite a distance, occasioning itching, pain, soreness or burning in the integument covering the course of the channel. here we have the pathological reason why local remedies to the outer surface of the skin will not cure pruritus ani. also the reason why dieting is useless, and why internal remedies are worthless for the cure of anal itching; for the itching, as shown, is the result of an inflammatory product in the channels under the skin of the victim, numbering from five to twenty. over fifteen years ago i discovered the cause of the great suffering from painful itching at the anus and contiguous tissues and have been able to give instant relief, and in a little time permanent cure, in every case treated since then. it is well for those who have an occasional attack of pruritus ani to take treatment at once for proctitis proper, as well as for this symptom, itching resulting from these channels. the proctitis, if neglected, will only be the means of increasing the size, length and number of these channels. in chronic, sub-acute and acute stages of proctitis there is more or less secretion of inflammatory product; and often the sufferer is able to discover, in dejections from the bowels, a yellow syrup-like fluid, of the consistency of glycerine or white of egg, at times streaked with blood and purulent matter indicating ulceration. should the proctitis be cured and these channels remain, there may be sufficient inflammatory product in the channels to ooze through the skin to the outer surface, and excite itching; or if a portion of the channel escapes treatment, the same symptom may be expected at any time. the size and length of these channels are best determined by making a small opening into them through the integument, then inserting a silver probe in both directions, determining the distance under the mucous membrane of the anal tube and the distance under the skin of the buttocks. in some cases a few of these channels open into the rectum just above the internal sphincter muscles and become filled with water during the use of the enema taken to move and cleanse the bowels. as a rule, one end of the channel is under the mucous membrane of the terminal portion of the rectum, and the other somewhere under the skin of the anus or of the buttocks. i presume that no disease of the human body has been assigned more reasons for its existence, with the exception of constipation, than that mere symptom of a disease, anal pruritus; a symptom which "regulars" call a "disease," but "irregulars" know to be only a symptom. it is very amusing to observe how they fill pages in their text-books, guessing, wondering and paying their respects to the imaginary quack doctors, "who are reaping a harvest of ill-gotten gain." the usual medical writer is a compound of ignorance, egoism and garrulity, and this may account for the great crop of reasons for "diseases." however, the writers in question are not so much to blame after all, even though they do belong to county medical societies; for how can they well resist the literary itch with which most of them are afflicted? let them keep on writing while victims of pruritus ani wear out their weary lives scratching through weary nights--nights that extend into years, until permanent invalidism seems to be their destiny and end. who, verily, are the medical quacks? i will leave it to a jury composed of those who have been cured of pruritus ani. i have yet to meet the first case of pruritus ani that is without the presence of the channels above described. there may be cases of itching at the anus and these channels entirely absent, but i have yet to discover such a case and i very much doubt if it exists. i am happy to inform the reader that all cases of pruritus ani are cured with ease and without any restrictions as to diet, and without internal remedies for the blood, nervous system, etc., given by doctors that guess. the causes are easily discovered; the symptoms are easily found and removed; the victim of pruritus ani may therefore escape from the labyrinth of error of the medical authors and practitioners who ought to be educators instead of "obstacators"--obstacles and stumbling-blocks in medical progress. chapter xxi. abscess and fistula. in our daily affairs we take thought for the future and reason from cause to effect. we observe, anticipate, expect and suspect. this is a commendable practice, for it is the one that is most likely to lead to success. can we not acquire a similar attitude and habit in regard to our health? habit is sub-conscious attention. can we not give sub-conscious attention to the little details of such bodily functions as are liable to get out of order? can we not by a settled habit, that is, by the formation of a second nature, assure our vital success, on which the continuance of the enjoyment of life so much depends? if some part of a complicated machine gets out of order it must be repaired at once or damage may result to other parts of it. again, if our business accounts will not balance, the error must be found and corrected at once, or the evidence of it will annoy us sooner or later. why should not such prompt care and attention be given to the human mechanism, to the economy of vital functions? it is not often that we neglect disease of the hands, head, face or neck because the exposure of such disease to public gaze might embarrass us; but alas for the portion of the body out of sight, especially for the internal organs, when they fail to perform their functions normally. most of us allow the mechanism of the human body to shift as best it can and as long as it can, should it happen to become ungeared, ignoring the frequent warnings which the ever increasing morbid changes and wreckage give us. and then we surrender and succumb. what else can we do? our vital creditors file their claims in the high court of vital bankruptcy. what poor business policy, and what a wretched tenant! for fifteen or more years we may have had warning "touches of the piles," sometimes accompanied with indigestion, constipation, diarrhea and insidious auto-infection and occasionally with local symptoms in and around the anal canal and its external orifice; these to an intelligent tenant should have been evidence of proctitis, or worse, of periproctitis--inflammation of the connective tissue of the rectal tube. what have we done? we have disregarded the warnings of our ungeared, disordered machine, or else we have merely tinkered with it. the human factory receives less attention than does the commercial. soon, all too soon, the silver cord is loosed and the golden bowl broken, and just before that event, frightened, but too late, we do a little more tinkering under a doctor's direction, and spill the contents--of the golden bowl with which we were so careless--spill it into another world, to begin our folly over again! do you know that this occasional "touch of the piles" over a period of many years, and all that it involves, is a precursor and an invitation to the development of that deadly enemy, cancer--a worse disaster than financial ruin? it is my duty to utter a warning here. only one making a specialty of the diseases of the alimentary canal is aware of the frequency of the occurrence of cancer in the lower bowel resulting from chronic inflammatory process, induration, etc. i have been, again and again, shocked and alarmed at the reckless neglect that has brought on this as yet incurable disease--cancer. these remarks apply well to what i have to say on abscess and fistula at the terminal portion of the intestinal canal. it is the old, old story of being "touched by the piles for many years," and neglect, ending in dread and despair at the necessity of being bored full of holes by pus seeking an outlet. the victim wonders at the spread of the local trouble, and that an opening for the pus canals has frequently to be made three to sixteen inches away from the seat of the abscess. in a former chapter the subject of proctitis and piles was gone into, and some idea given of the invasion of inflammation in the rectal and anal tissues. in exceptional cases the exciting cause of anal and rectal abscess and fistula, or of abscess and fistula of the buttocks, may be a traumatic injury or accident, produced, say, by a blow or a fall bruising the tissues, or by sharp, hard substances--such as pieces of bone or nutshell--from within the canal, lacerating it. but wounds of this character are very infrequent compared with chronic inflammation (proctitis) as the exciting cause. there are several varieties of proctitis recognized as the exciting cause of abscess and fistula, namely, traumatic, dysenteric, diphtheritic, gonorrheal, catarrhal, etc. the reader should not only pardon me, but should be grateful if by adding another name to the list i point out the most common cause, namely, _diaper-itic proctitis_. as pointed out in the first chapter or two, the improper use of the diaper will evidence its deplorable result when the period of manhood or womanhood is reached, by some of the many symptoms of proctitis. proctitis may be considered as acute, subacute or chronic according to the duration of the process; or as atrophic or hypertrophic from the structural changes induced. but no matter about the cause and character of the proctitis, the question is, have you inflamed anal and rectal canals? if you have, then the very annoying symptom, abscess or fistula, is liable to occur any day. can you afford to take the chances? just under the mucous membrane of the anus and rectum there is a layer of loose, fatty, connective tissue, called areolar tissue. when it is invaded by inflammation, abscess and fistula may occur. on the outside of the rectal wall, at the terminal portion, there is also much loose, fatty (areolar) tissue filling the ischio-rectal fossa, which is very prone to suppuration, and inflammation here is called periproctitis. this is the most common and serious seat and source of the septic process, which process is usually the proximate cause of death after capital surgical operations upon the rectum. beside the abundance of fatty tissue--whose function is to serve as a cushion to the rectum at its terminal portion and at the back and sides of the wall--there is a triangular space in front of the rectum containing fatty areolar tissue, which space is often the location of a pus cavity. pus, like all fluids, follows the path of least resistance. the progress of imprisoned pus may take weeks, months and years before an abnormal communication between the abscess and the external portion of the body is completed. the imprisoned contents of the abscess cavity and the pus canal or fistula often give rise to much annoyance before finding an outlet. there will be pain in the muscles of the buttocks, called myalgia; and pain at the end of the spine, called coccygodynia. for this latter pain do not, i pray you, as is so often done, have your spine removed by the too ready surgeon. no need of it at all. you might just as sensibly have the muscles cut out for myalgia. pus in fistulous channels may burrow for several years through the muscular and connective tissue structures before finally forming an external opening through the integument; although its nearness to the surface is frequently marked by a localized puffiness and inflammation, which, however, may disappear for a time without forming an external opening. this condition of affairs results in periodical attacks of coccygodynia, myalgia and neuralgia of the buttocks and lower extremities. the important question with the victim of abscess and fistula is, "how did i get it? i don't care for the various and numerous names you give to these fistulas: what i should like to know is, how does it come about that i, an apparently healthy person, have such a nasty disease?" simply years of neglect, is my answer. neglect is due sometimes, and perhaps generally, to ignorance of the thing neglected. the laity can in large measure blame the medical profession for it, and especially those surgeons who have long made a specialty of the treatment of anal and rectal diseases. chapter xxii. the origin and use of the enema. pliny recorded the fact that "the use of clysters or enemata was first taught by the stork, which may be observed to inject water into its bowels by means of its long beak." the _british medical journal_, reviewing the newly published _storia della farmacia_, says that frederigo kernot describes in it the invention of the enema apparatus, which he looks upon as an epoch in pharmacy as important as the discovery of america in the history of human civilization. the glory of the invention of this instrument, so beneficial to suffering mankind, belongs to an italian, gatenaria, whose name ought to find a modest place together with columbus, galileo, gioja and other eminent and illustrious italians. he was a compatriot of columbus and professor at pavia, where he died in 1496, after having spent several years in perfecting his instrument. the enema apparatus may be justly named the queen of the world, as it has reigned without a rival for three hundred years over the whole continent, besides brazil and america. the enema came into use soon after the invention of the apparatus itself. bouvard, physician to louis xiii, applied two hundred and twenty enemata to this monarch in the course of six months. in the first years of louis xiv it became the fashion of the day. ladies took three or four a day to keep a fresh complexion, and the dandies used as many for a white skin. enemata were perfumed with orange, angelica, bergamot and roses, and mr. kernot exclaims enthusiastically, "_o se tornasse questa moda!_" (oh, that this fashion would return!). the medical profession at first hailed the invention with delight, but soon found the application _infra dig._, and handed it over to the pharmacist; but shameful invectives, sarcasms and epigrams, hurled at those who exercised the humble duty of applying the apparatus, made them at last resign it to barbers and hospital attendants. (_year book of therapeutics_, wood, 1872.) "the history of the warm bath," says dr. paris, "presents another curious instance of the vicissitudes to which the reputation of our valuable resources is so universally exposed. that which for so many ages was esteemed the greatest luxury in health, and the most efficacious remedy in disease, fell into total disrepute in the reign of augustus, for no other reason than because antonius musa had cured the emperor of a dangerous malady by the use of the cold bath. the most frigid water that could be procured was in consequence recommended on every occasion.... this practice, however, was doomed but to an ephemeral popularity, for, although it restored the emperor to health, it shortly afterward killed his nephew and son-in-law marcellus, an event which at once deprived the remedy of its credit and the physician of his popularity. "that the _warm_ and not the _cold_ bath was esteemed by the ancient greeks for its invigorating properties may be inferred from a dialogue of aristophanes, in which one of the characters says, 'i think none of the sons of the gods ever exceeded hercules in bodily and mental force.' upon which the other asks, 'where didst thou ever see a cold bath dedicated to hercules?' "thus there exists a fashion in medicine, as in the other affairs of life, regulated by the caprice and supported by the authority of a few leading practitioners, which has been frequently the occasion of dismissing from practice valuable medicines and of substituting others less certain in their effects and more questionable in their nature. as years and fashion revolve, so have these neglected remedies, each in its turn, risen again into favor and notice, whilst old receipts, like old almanacs, are abandoned until the period may arrive that will once more adjust them to the spirit and fashion of the times." (j. a. paris, _pharmacologia_, p. 31, new york, 1825.) "a story told of voltaire," says dr. arthur leared, "well illustrates both the evil effects of constipation and the advantage of using the enema. the great philosopher was one day so miserable and dejected that he told a friend he had resolved to hang himself. his friend called the next morning to ascertain whether the resolve had been or was intended to be carried out. but voltaire only replied, with a smile, 'i have been well washed out this morning.'" (op. cit., p. 200.) for those suffering from chronic intestinal uncleanliness or constipation, an occasional intestinal wash-out, or bath, is quite as satisfactory as an "occasional" external bath or the "occasional" use of a cathartic medicine. if there is a necessity for cleansing and purifying the bowels at all, why not do it properly and systematically until the condition that made the artificial cleansing necessary is removed? who would tolerate the cleaning of dining-room, kitchen, dairy and other utensils in domestic use only when they became so foul that they could not be endured any longer without great annoyance? away with the "occasional" cleansing habit for either external or internal bodily cleanliness! there are persistent causes for internal uncleanliness, for the tardy action of the bowels, which require regular periods for cleansing until cure is effected. it is estimated that food taken into the stomach will reach the colon in five hours. for nineteen hours the sewage waste of the body is gradually becoming a fetid pool before an outlet is furnished it by the one-movement-a-day people; and o ye gods of health! how many of us there are that haven't even one movement a day! for a few hours the absorbent cells of the colon will try to extract as much of the nutritious residue as the system calls for, but along with it a lot of poisonous filth will be absorbed. the call of the system for nourishment should be fully answered by the small intestines. savages have four or five movements a day, and we certainly should not have less than three. people of refined sentiments will, at such a disclosure, bestir themselves to better things. water, when properly applied, is the only remedy that meets the physiological and pathological requirements of the chronically constipated. by its use the diseased, spasmodically contracted muscular tube is simply dilated, and the imprisoned feces and gases above are permitted to pass down and through the temporarily occluded section of the diseased bowels, the patient will have the consciousness of neatly accomplishing an imperative requirement, and the satisfaction which cleanliness entails. chapter xxiii. how often should an enema be taken? the following lines will show you how advertising is done in medical journals. "dear doctor: the spring being the time for cathartics, i beg to call your attention to r. l. (yellow label),..." why is spring a special time for cathartics? has the intestinal canal been obstructed like the erie canal during the winter months? with as much propriety they might advertise: "dear doctor: the spring being the time for bathing, i beg to call your attention to antiseptic bath soap,..." i suppose that a sort of annual cleansing of the alimentary canal is suggested so that the summer heat may be less objectionable, as it warms up foul bodies. however, attention once a year is better than none at all, as said of the augean stables. not long ago i had a conversation with the proprietor of a bath cabinet company, who had given some thought to hygienic measures, and he considered it essential to flush the bowels with water once a month to secure "proper cleanliness." this opinion is quite in advance of the annual cathartic cleansing. some people may have acquired the habit of a monthly cathartic "cleansing"; others wash out once a week, and a few once a day: all of them act from their idea of cleanliness, as they would perform the ablution of their hands, face and body. there are some hygienic students who have adopted the idea of "cleansing" the bowels with warm water once or twice a week, which practice is quite in advance of the annual or monthly attention. all have reasons for the manner and time they adopt to "cleanse" the bowels; and yet they find that they are not cleansed properly, as they still have spells of biliousness and misery. they wonder at themselves for being so rash and bold as to take an enema twice a week, and begin to feel that they have reached a point of positive danger. one anxiety is that they will weaken the bowels by the use of a pint or a quart of water once a month, or once or twice a week. another is that they will wash away the mucus, leaving the membrane of the bowels as dry as an oven. another is that they will form the dreadful habit of using the enemata. what a pity to form such a cleanly habit! sorry for them! another stubborn objection is, that flushing of the bowels is not natural. these foolish objections and fears can be attributed to medical authors who belong to medical societies. it is very strange how these authors adopt so many wrong notions about the physiology and pathology of the bowels. what an erroneous and absurd idea that the enema should weaken the bowels! why should it? exercise ought to strengthen muscular tissue; and what could give the bowels more gentle muscular exercise than the proper use of them? has the reader any idea of the amount of water requisite for the distention of an elastic muscular tube, about five feet in length and two and a half inches in diameter in the widest part? the large intestine is capable of great distention, as is frequently demonstrated in fecal impaction described in previous chapters. the quantity is named in gallons. the amount of water usually injected at one time--from one pint to two quarts--can hardly be said to distend the bowels at all. i wish the enemata did have power to weaken that part of the bowel involved in disease. i am very sorry it does not weaken it. for twenty years it has been demonstrated to my mind that almost every case of chronic constipation, biliousness, intestinal foulness, diarrhea, indigestion, self-poisoning (auto-infection or auto-intoxication) was due to too much activity and vigor of the lower bowels, this excessive activity and vigor being the result of chronic proctitis, colitis, etc. to lessen this muscular irritability, and to devise means to relieve and cure quickly, has cost me more studious hours than the aggregate of all the other diseases and symptoms of the lower bowels. if liquids washed away the mucus from the mucous membrane, the throats of many individuals ought to be very harsh and dry, inasmuch as six to eight glasses of liquids pass through their mouths and throats during every day of twenty-four hours. even after the "dry feeling in the throat and stomach" has been bountifully attended to by the owner, the conversation usually becomes more loquacious and hilarious, and there is no suggestion that the intemperate person had spent many hours in a hot desert without water. the frequent flushings they give their throats and stomachs really do not seem to wash the mucus away. when a person consults an oculist about an affection of the eyes and glasses are prescribed, good sense will inform him that the glasses must be worn while the imperfect functioning of the eyes requires them. if a limb be fractured and splints be applied, would you worry lest you form the habit of wearing them? certainly not; you expect in due time to recover the proper use of the limb. so if you are compelled to use crutches you do not worry about forming the crutch habit, for you will use them as long as needed and discard them at the proper time. as to its being unnatural to flush the bowels with water, i would say that it is very unnatural to suffer from proctitis accompanied with its annoying symptoms, such as constipation, indigestion, diarrhea, auto-intoxication, emaciation, anemia, muddy complexion, foul breath, blotches and pimples on the face, each and all of which indicate a physical debasement. it is unnatural to wear glasses, crutches, splints, wigs, artificial teeth, artificial eyes, but many people do such unnatural things. many of our habits are not exactly "natural," but they are rational, none the less; such, for example, as bathing the body night and morning; cleansing the mouth and teeth after each meal; and the nostrils and ears several times a day. the frequency of these practices may, with some people, be unnecessary and useless, but no real harm is done by their scrupulous cleanliness--physical and mental. proctitis is usually worse than it seems to be. this is because of the insidious progress of the inflammation during the fifteen, twenty or more years before the local symptoms at the anus or in the anal canal are sufficiently annoying to compel the sufferer to seek treatment. such sufferers are, as a rule, born with the idea that the liver regulates the whole alimentary canal; and if the sufferer has not this hereditary notion, his physician will soon impart it to him with his diagnosis and treatment. the disciple of cathartics, whether the cathartics be in the form of pills, powders, or solutions, or contain belladonna and opium to overcome the cramping pain the dose would otherwise occasion, has no legitimate reason to indulge in the hope of a cure or of even moderate relief of the real source of trouble--the proctitis. it is proceeding on the liver theory, when the key is, as has been shown in these articles, _proctitis_, inflammation of the anus and rectum. physicians ignorant of the key to all bowel troubles even prescribe strychnine in order to stimulate bowels which have already an excessive amount of stimulation due to the presence of the proctitis, which, as has been said, over-stimulates the lower bowels because of the inflammation. the chronic character of proctitis of many years' duration, improperly diagnosed and treated, must necessarily compel a rather long and continued use of the enema, especially so if not accompanied by proper local treatment of all the inflamed surface. i should not care to treat patients suffering from proctitis, constipation, etc., unless they used the enema twice a day. the feces and gases should escape the bowels at least twice in twenty-four hours. any less than two stools a days is abnormal and will result in infection and disease. you may not always succeed in having two stools when first treating the local disease, but what you properly start out to accomplish will be attained in due time. free evacuation of the contents of the bowels should occur at least twice in twenty-four hours. this can be accomplished by injecting into the colon from one to four quarts of warm water. before taking the large injection, relieve the bowels of any gas seeking liberation, and of course, also, of whatever feces may come readily. then take a small injection, using very little water: just enough to bring on a relief of as much feces and gas as possible. it is not well to drive the gas back and up into the colon; hence the precaution to suggest a further passage with a small quantity of water before taking the large injection. enemata, and also the use of the recurrent douche, can in no way be harmful--if the water be of a proper temperature--to a normal or even to a diseased bowel; therefore the fear of habit is absurd and should not receive a moment's consideration. the length of time during which the enemata and the douche are to be used, whether months or years, will depend on the character of the disease that made its use necessary. chapter xxiv. man's best friend. travel the world from end to end you ne'er will find a better friend than sparkling water, pure and free, most precious boon to you and me. it cheers the faint, it crowns the feast, makes food to grow for man and beast; in sickness soothes the fevered frame, there's healing in its very name. and what can more life-giving be than cooling breezes from the sea, whose bosom bears upon their way the stately ships from day to day? a treasure trove of priceless worth; a jewelled belt for mother earth, encircling with its silvery bands, she binds together many lands. to cure disease dame nature brings her remedy in mineral springs; water without, water within, equally good for stout or thin; and more than man can e'er devise invigorates and purifies. travel the world from end to end, you ne'er will find a better friend. chapter xxv. physiological irrigation. the scientific irrigation of land is pretty well understood by those who have financial interest in soil requiring it. the wonderful beauty and freshness of flower and fruit give evidence of what scientific irrigation can do. so from a commercial and esthetic point of view the proper amount of daily moisture for land, tree or vine, is of such importance that it receives the consideration of those interested. how many persons, however, in the course of a lifetime have given ten minutes to serious consideration of the question: _how much water should be imbibed daily under the varying conditions of the body's garden?_ those who give no consideration to the problem of how to attain and maintain a healthy and vigorous physical basis are persons who usually drift into habits for which they will, sooner or later, have to pay the penalty. for the first twenty or more years the body is, as a rule, unfortunate in not having an intelligent tenant. for man misuses his physiological estate, and lets things go to rack and ruin ere he wakes to realize how it might have been as to length of days and strength of body and mind. enlighten him, after he has reached adult years, on the values and needs of physiological and psychological functions; you will find that however eager he may be to follow the light he is handicapped by vicious habits and by confirmed, destructive changes which had seized on him when he was quite too young and incompetent to care for his body. what a topsy-turvy world this is, to be sure! it is astonishing what a number of people there are who drink little or nothing, and especially amazing is it to find this lack of sense in people suffering from constipation. one would suppose that they above all others would see the wisdom of irrigating their bowels. but it is seldom that there is one who thinks of such a thing. a cup of coffee or tea at meal-time, in addition to the liquid contained in the food, is the extent of water consumption by ever so many teetotalers and other "totalers," especially women, until they reach, say, thirty years of age. such persons as a rule are not long-lived, inasmuch as their power of resistance is small, owing to their lack of blood, a lack in quality as well as in quantity. the blood pressure in their arteries and veins is light, as evidenced by their pale, sallow complexion, and the dry, scaly, feverish skin, which seldom or never perspires. the body garden has not been properly irrigated and is slowly drying up as age advances. did you ever notice how like death such persons appear when they are asleep? their dull, pasty complexions alarm us then. when i see them a desire to soak these dried specimens of humanity possesses me. is it not unfortunate that we were not born with an automatic irrigator? we even lack a tube on our boiler to indicate the danger point! deficient by nature in these little conveniences, and unaided by science, man is compelled to give some attention to the irrigation of his physiological soil, however indifferent or careless he may be. planters and gardeners have treatises on irrigation. have mothers or nurses any similar guides? such books are unknown to modern civilization. infants, boys and girls, and adults are brought up haphazard, and their garden of life becomes choked with weeds. the drought soon makes itself felt, and a little graveyard mound is their usual fate. before some of us wither and fade, to what a pest-weed is our adipose changed for want of life-giving water. man's most serious physiological fault is the toleration of constipation; or even of semi-constipation induced by the twenty-four-hour habit of stooling. in other words, his fault is the toleration of intestinal uncleanliness. and next to this foolhardiness is his negligence in the matter of drinking daily a quantity of pure soft water sufficient to aid in the proper stimulation and circulation of the blood, in the proper elimination of the waste material from the body, and in the proper assimilation of nutriment by the system. if parents would encourage their children to become bibbers of pure spring water daily it would not be easy to make them bibbers of intoxicants in after years. i would give a child all the liquid it desires, i would even encourage it to take more rather than less, and the best liquid of all for this purpose is pure soft water. man's body is 70 per cent water. it is therefore a good-sized water cask with a ramification of countless canals or pipes imbedded in soft connective tissues, nerves and muscles, all of which are supported by a bony framework; through the centre of this runs the alimentary canal, down which waters may flow and disappear like unto a stream lost in the sand, to reappear and ooze from skin, lungs, kidneys and intestinal canal. every organ and tissue luxuriates in water; they lave and live in and by it. with all kinds of food it is introduced into the body. water acts as a solvent for the nutritious elements and as a sponsor for the elimination of foreign substances and worn-out tissues of the system. it also serves to maintain a proper degree of tension in the tissues, which tension is essential to the proper circulation of the lymphatic fluids. the tonic reaction of externally applied water is well known. but the advantages of the internal use of water are hardly known at all because the reactions of the circulation, temperature, respiration, digestion and secretions are less noticed. two or three pints of cold water at a temperature of forty to forty-five degrees drunk at intervals of half an hour will reduce the pulse from eight to thirty beats. the copious drinking of cold water will act as a diuretic, removing stagnated secretions, and will at the same time improve the quality of the pulse and the arterial tone. the drinking of warm water will increase the pulse from five to fifteen beats, and at the same time will relax the vessel walls and also increase the cutaneous secretions to a marked degree. the drinking of a large quantity of water not only increases the secretions of the kidneys--assisting them in the work of carrying off solid constituents, especially urea--it also increases the secretions of the skin, saliva, bile, etc. under proper conditions the internal use of water acts as a stimulant to the nerves that control the blood-vessels, a stimulant similar to that produced by its external application. i advise the drinking of a copious quantity of water daily. there need be no fear that this practice will thin the blood too much, as the ready elimination of the water will not permit such a result to ensue. i would further advise the generous use of water (temperature 60â°) at meal-times. i pray you do not drink to wash down food: a bad habit of most of us. drink all you desire; and if you are like many who have no desire for water, cultivate it, even if it takes years. the imbibed water will be in the tissues in about an hour; and the entire quantity will escape in about three and one-half hours. the demand on the part of the system for water is subject to great variation and is somewhat regulated by the quantity discharged from the organism. physiologists declare that water is formed in the body by a direct union of oxygen and hydrogen, but those who have cultivated the drink-little habit need not hope to find an excuse for themselves in this fact: chronic ill-health betrays them. water in organic relations with the body never exists uncombined with inorganic salts (especially sodium chloride) in any of the fluids, semi-solids, or solids of the body. it enters into the constitution of the tissues, not as pure water, but always in connection with inorganic salts. in case of great loss of blood by hemorrhage, a saline solution of six parts of sodium chloride with one thousand parts of sterilized water injected into the system will wash free the stranded corpuscles and give the heart something to contract upon. when water is taken into the stomach, its temperature, its bulk, and its slight absorption react upon the system; but the major part of it is thrown into the intestinal canal. when it is of the temperature of about 60â° it gives no very decided sensation either of heat or cold; between 60â° and 45â° it creates a cool sensation, and below 45â° a decidedly cold one. water at a temperature of about 50â° is a generator of appetite. a sufficient quantity should be taken for that end; say, one or two tumblers an hour or so before each meal, followed by some exercise. those who have acquired the waterless habit, and the many ills resulting from it, will hardly relish cool water as an appetizer; but if they would become robust they must adopt the water habit--a habit that will refresh and rejuvenate nature. water of a temperature between 60â° and 100â° relaxes the muscles of the stomach and is apt to produce nausea, especially if the effect of bulk be added to that of temperature. lukewarm water seems to excite an upward peristalsis of the intestines and thus produces sickness. hot water acts as a stimulant and antiseptic, as a sedative and as a food. water at a temperature of 110â° to 120â°, or more, will nearly always relieve a foul stomach and intestines. it should be slowly sipped, so that the stomach may not be uncomfortably distended. after imbibing a pint or a pint and a half, wait for fifteen or thirty minutes to give it time to pass into the bowels, then drink more if thought advisable. drink it an hour before meal-time. it will excite downward peristalsis, will dilute the foul contents of the stomach, and will thus aid the escape of these contents into the intestines, which latter require the washing process as well. sometimes it is a good thing to omit one, two or three meals while the washing process is being continued. commence treatment with pure hot water. to make it appetizing, add a pinch of salt or of bicarbonate of soda; with children add sugar. it will pay you to follow this treatment for the cleansing of the alimentary canal. the vitality of the body may be sustained for days and weeks on water alone; there is therefore no hurry about food. if human beings would only keep their bowels and stomachs clean they would avoid all the ills that flesh is heir to, except, of course, those due to accident. my remarks have been confined to irrigation _per orem_ (that is, by way of the mouth), and nothing has been said of irrigation _per anum_ (by injection), since i have treated the latter subject fully in several previous chapters, to which the reader is referred. be sure to follow the counsel there given, and use the enema two or three times a day in moderate quantities as indicated. chapter xxvi. proper treatment for diseases of the anus and rectum very essential. no doubt the readers of the preceding chapters on proctitis and its numerous symptoms--noted under separate headings--would like to know something about the home treatment for such an insidious and grave disease. every sufferer wants to be a self-doctor. this commendable desire it is usually impossible to put into practice. if physicians so often fail to cure the ailments i have described, what can be expected of those who have no knowledge at all of diagnosis and treatment? a skilful physician is the choicest gem of civilization, and an intelligent patient its worthy setting. surely it is a moral crime, an inexcusable folly to tolerate a disease with its inevitable train of dire consequences, up to the point when the discomfort compels one to seek treatment. there are patients, of course, who have good and sufficient excuses for their painful predicament; they have, for example, tried persistently for relief and cure, but have failed to find a physician competent to treat their particular case. how many unskilled prescribers there are, and how glaring their shortcomings! some hold out taking inducements to sufferers; their one object being to transfer their patients' cash to their own pocket. 'twere charitable to consider these ignorant; but alas! many of them are poisoned by the "fakir" germ. stuff is sold by the conscienceless, claiming to cure "piles," to "give instant relief," and promising "a complete cure in a few days"; and as to itching piles, why! "only a few applications are necessary for a cure; six boxes for five dollars"! etc. no remedy that sufferers apply themselves can be more than a temporary relief: it cannot really cure piles, polypus, fistula, tabs, pruritus (itching)--all of them consequences of proctitis. of course one should be thankful for the little relief to be got temporarily from advertised and drug-store drugs; nothing more than relief can be expected of them. there are indeed times when a palliative treatment will serve to tide the sufferer over a few days until he is able to consult a competent physician. but how strange it is that so many sufferers regard their anatomy and physiology so lightly as to think of using remedies, even for relief, without first undergoing a thorough examination by a competent physician. in troubles of a rectal character it is exceedingly foolhardy to allow any one to prescribe without insisting upon a thorough examination to ascertain whether there be any disease of a cancerous nature present, or what the trouble actually is, and its progress. to expect one remedy or prescription to meet all the requirements for the cure of a chronic disease of the anus and rectum and of the many complications accompanying it is hardly sensible, but that is just what a great many do expect. no one remedy in the market, or any number of them combined can effect a cure, for the simple reason that proper local treatment by a physician is of paramount importance. unless of a traumatic (externally produced wound) origin, diseases of the anal and rectal canals are usually of fifteen, twenty or more years' incubation before the annoying symptoms become apparent. this accounts for the slight attention to the maturing trouble and for the fact that such attention can afford nothing more than a palliation or postponement. a real cure requires a combination of means, all working harmoniously for the proper length of time. proper treatment and the proper time are the two prime requisites; and the third and final requisite is, of course, a sensible patient. before home treatment is to be thought of it is accordingly advisable to have an examination and a prescription for the specific local treatment necessary for a trouble like piles, fissure, polypus, tabs, itching, fistula, varicose veins, abscess, ulcer, granulation, hypertrophy, or atrophy as the case may be. the local treatment can best be aided by a combination of remedies with suitable instruments for their use between the periods of local attention by the physician. the writer of this has no cure-all to send the sufferers, although it might be to his financial advantage to have one; he is, however, always ready to advise and relieve those who cannot visit him immediately. the relief afforded often facilitates the cure by permitting a more extensive local treatment at the first visit. _the use of instruments for injecting water._ to do something at home for one's self for relief from soreness and pain due to anal and rectal diseases, a few suitable instruments are required with which specific remedies may be used, especially that excellent remedy--water. it is unfortunate that the anal and rectal canals cannot be given rest when invaded by disease. daily elimination of feces is a very important factor to health and to treatment. to accomplish this the very best means is water in various quantities as the case demands. it does not irritate the diseased canals--as cathartics do--but aids in the escape of imprisoned feces and gases which lodge above the region of the morbid process. evacuation should be accomplished twice a day, by the injection at first of three or four quarts of water--thus obtaining a good daily flushing of one's sewer--and then, if advisable, gradually lessening the quantity at subsequent injections to one or two pints at a time. the temperature should be 100â° to 105â° or more. some people have an idea that water at the temperature named has a remedial effect on an inflamed anus and rectum. it has none whatever; all it does is to wash away the deposits which might irritate the inflamed surface. water at a temperature of 100â° to 105â° is not an especially good antiseptic; and its intestinal use should not be continued longer than to bring away the effete and fetid material which may be lodged in the colon, sigmoid flexure and rectum. in the majority of cases its use should be limited to aiding the feces to escape from their normal receptacle--the sigmoid flexure--whenever proctitis does not extend beyond the rectum. but many persons are deceived by the conduct of proctitis and are thus likely to omit the regular irrigation twice a day. they believe themselves to be in pretty good condition and do not realize that their old, implacable enemy may be excited into riot any day; in which case the insurrection may last for months and then slowly settle down to semi-quiet again, reaching finally the point of its best behavior for a short period or until again provoked. _the use of the recurrent douche._ water at a temperature of 120â° to 130â° properly applied is a good therapeutic agent in the treatment of proctitis. at that temperature it is an excellent antiseptic and astringent. its continuous use for half to one hour applied with a recurrent douche brings about a contraction of the engorged and dilated blood-vessels; and accompanied by local treatment and by other remedies is the best means known for restoring the nerves to their normal function of controlling the proper circulation of blood in the diseased organ. treatment with the recurrent douche is of course to follow, not to precede, the evacuation of the bowels; but at any time when there is a tendency toward additional evacuation on the admission of the hot water, the new douche is easily adjustable to the contingency without removal from the anal canal; it will facilitate the escape of the feces with the return flow of the water. the new recurrent douche has therefore the great advantage of promoting simultaneously both the thorough evacuation of the bowels, and the therapeutic effect of hot water. _sitz-bath._ there are patients who, because of years of neglect of their local ailments, are taken with severe attacks of inflammation of the anus and rectum, involving considerable prolapse, much swelling around the anus, and general local soreness and pain; all of which is often accompanied by a general disrelish of life. for this condition nothing is so good as a very hot sitz-bath, if properly adjusted to the parts and continued for about an hour at a sitting. the alleviation afforded is so decided and the local and prolonged application of hot water so restorative that it may be left to the sufferer to determine how often this bath is to be repeated. it may be taken as often as there is an inclination to do so. the sitz-bath apparatus should be scientifically adapted to the parts so that the bather will not sit lower than ten or twelve inches, thereby avoiding a straining position. during the bath there should be more or less pressure against the anal tissues, which assists the hot water in expelling the blood from the inflamed parts. from the beginning to the end of the bath the water must be as hot as the tissues will tolerate. only a small portion of the buttocks need be immersed in the hot water. _spring water the ideal beverage._ those who suffer from disease of the rectum, with rare exceptions, are constipated or semi-constipated, which condition in turn aggravates or disturbs the inflamed parts. to overcome this constipated condition all sorts of laxatives are taken, which will in the end do grave harm not only to the whole system, but especially to the inflamed parts, irritating them still more. there is a valuable therapeutic agent seldom taken by the constipated; in fact, it is never thought of; unfortunately the remedy is not easily to be had in its pure state by most of us, boxed as we are in cities. sold under various names as mineral water, it is too often adulterated. 'tis a simple remedy, and yet it has a wider range of healing power than any other; a universal solvent, applicable to all diseases and all states of health. i would write it at the head of all remedial agents: pure spring water! we do not drink enough water. if we were to imbibe at least two quarts of pure water daily we would be healthier and have better movements of our bowels. water may be taken freely during mealtime; not, however, for the purpose of washing down half-masticated food. alcoholic drinks, coffee and tea would better be dispensed with, also tobacco. the nervous system has enough to bear without the use of avoidable irritants. _other hygienic agencies._ too much cannot be urged as to the advisability of a proper amount of exercise, sleep, rest, food, breathing, cleanliness (internal and external), as well as and above all, pure, high-minded thoughts and serene temper--the outcome of the habit of viewing life philosophically. care should be taken to protect the feet and body from sudden climatic changes, thus avoiding catarrhal troubles, especially of the lower bowels. as to the wise and proper use of nature's pharmacopoeia, nothing need be said here. however, i may be within my limits when i advise patients to use a little sense and not neglect disease of the lower bowel any more than they would neglect that of the eye, ear and throat. in the latter case they submit at once to an examination. why not in the former? let them bear in mind that the cure of chronic proctitis is no holiday job; that it is, on the contrary, a task which requires constant attention. to merely relieve the annoying symptoms that accompany it cannot be called a cure. but on the other hand relief may be the commencement of a cure. of course the true way of looking at the subject of this disease is to regard the cure of proctitis as necessarily leading to the disappearance in time of all the other troubles that were the outcome of that ailment. through the harmonious efforts of patient and physician, marvellous results are often obtainable. chapter xxvii. the body's book-keeping. man's food is as varied as his work, more varied than the climate, with one food for the luxurious and one for the poor. the majority of us take what we can get, making no complaints; even when we have a cook and a good one the same is true. the ideal diet prepared by the ideal cook no one has as yet made fashionable, but one thing is within the reach of all--cleanliness of the sewers of the body. keep the contents of the bowels moving down and out steadily and regularly and you may eat almost any food and in almost any preparation and still be healthy. just as a steam-engine, running at a given rate of speed, must be supplied with fuel sufficient to maintain that speed, so the human body must have the requisite food to maintain the speed of civilized society and business, and replace the waste of the tissues; otherwise decline sets in and the reserve store of strength is exhausted. how shall we determine the proper amount and kind of food for the various ages, sexes, and conditions of life? a leading authority says that the character and amount of the daily excreta furnish suggestions as to the required food supply. (kirk's _physiology_, p. 208.) these excreta are found to be carbon, nitrogen, hydrogen, oxygen in great part, with some sulphur, phosphorus, chlorine, sodium, etc. a summary is given (_ibid._, p. 432) of the expenditure for twenty-four hours: 1. from the lungs: carbonic acid about 15,000 grains water " 5,000 " 2. from the skin: water " 11,500 " solid and gaseous matters " 250 " 3. from the kidneys: water " 23,000 " organic matter " 680 " saline bodies " 420 " 4. from the intestines: water " 2,000 " organic and mineral substances " 800 " total daily expenditure: solid matters " 17,150 " water " 49,500 " altogether about eight and a half pounds. the credit side of the sheet is about as follows: solids (chemically dry foods) " 8,000 grains water, combined or otherwise 35,000 to 40,000 " oxygen, absorbed by the lungs " 13,000 " altogether about eight and a half pounds. with the proper balance between the intake and the outgo, the functions of the body will be carried on normally, but the balance must be a proper one; that is, not only must the entire waste be repaired but the correct proportions of one kind of food and another must be observed. if all the elements needed are not furnished there can be no true counterpoise. how do we expend the energy? by the common wear-and-tear incident upon all voluntary motion, all work and recreation, carrying on the internal movements of digestion and respiration, by thinking, by loss of temperature, by indulgence of any of our functions, and by any wrong indulgence especially. excessive use, voluntary or otherwise, will of course diminish our total capital and cut short our lives. could we always maintain the right balance we need never die. the importance of what has been said must now be clearly apparent. we ought to be wisely interested in choosing the proper foods for our daily needs and in having them properly prepared; we ought to know how much carbohydrates we need, how much proteids, and regulate our diet accordingly. the foods which contain nitrogen are chiefly the following: flesh of all animals, milk, eggs, leguminous fruits (peas, beans, lentils); those which contain carbohydrates chiefly are bread, starch, vegetables and especially potatoes, rice, etc.; foods supplying fat are butter, lard, fat of meat, etc. salts are furnished in almost all other substances, but especially in green vegetables and fruits. liquid food is obtained by water, too often neglected, and tea, coffee, beer, cider, etc. alcohol has no power to form tissue or to repair waste and cannot be regarded as a true food. tea and coffee are almost entirely stimulant, not nutritious, and should be taken sparingly or not at all. the common mistakes in diet are over-feeding or taking too much of one kind of food, and of the latter class perhaps an excess of starchy food is the most mischievous. if taken in excess, especially by the young, the starchy foods are not digested and what does not digest must putrefy: the result is a bowel distended with harmful gases. many people eat too much nitrogenous food, with resulting plethora or gout. a great deal of vigorous exercise in the open air is required to use up such a diet. chapter xxviii. selection and preparation of food. the requirements for normal digestion, assimilation and elimination are: (1) an intestinal canal clean and sound from mouth to anus; (2) nutritious food properly prepared; (3) regularity and moderation in eating; (4) free use of pure water, sufficient to forward the emulsification and assimilation of the food and the elimination of waste--whether that waste be of the residual portion of the food or of detritus of tissue; (5) a seasonably clad body, free from fatigue or loss of sleep; (6) a cheerful mind. every sensible person will grant that a good digestion of vegetable or animal food furnishes sufficient steam and stimulus for the physical man; that a good digestion of intellectual food (ideas) furnishes the corresponding requisites for the mental man; and that exalted sentiments are the pabulum of the spiritual. why over-stimulate the physical, and reflexively degrade the mental and spiritual, by indulgence in tea, coffee, beer, wine, liquors, opium, tobacco, etc.? over-stimulation will bring on indigestion; and prostration will follow that. remember that nature does not carry long credit accounts. a suggestion for the selection and preparation of physical foods is here given; this book being hardly the place for a corresponding list of mental and spiritual foods. foods easy of

for indigestion. indigestion is a symptom of a functional disturbance or is due to a local disease in some portion of the digestive apparatus. therefore diet must be adapted to the sensibility of the stomach and bowels, to gastric and intestinal secretions, mobility, absorption and elimination, to the abnormal increased feeling of hunger or to the absence of the sensation of hunger. the food should be of easy solubility and offer slight resistance to the digestive juices. it should not mechanically or chemically irritate or impede intestinal peristalsis. it should not increase fermentation or putrefaction and the greater portion of it should be absorbed. the object of diet is not to eat less food than usual but to secure more nourishment until the proper quantity is consumed each day. the restriction of foods does not mean limitation. regular hours for meals should be religiously observed by sufferers from indigestion. the food should be thoroughly masticated. good judgment should be used by each individual in selecting and preparing the foodstuffs; also in the amount taken at each meal, and the proper length of time to continue the diet. you may take: _soup_--in moderate quantity: doxsee's clam juice, and little neck clams; cream of peas, etc.; vermicelli; tapioca; tomato; clear soups of chicken, beef, mutton. _fish_: trout; bass; perch; shad; weakfish; whitefish; smelts; raw oysters. _meat_: roasted or boiled beef; mutton; venison; calf s head; tongue; sweetbread; lamb chops; squab; roasted partridge; pigeon; calf's-foot jelly; armour & co.'s vigoral; valentine's or wyeth's beef juice, or wiel's beef jelly. _eggs_: raw; soft-boiled; poached; omelette; eggs on toast. _bread_--all over a day old: brown; graham; gluten; rye; zwieback; crackers; cracked wheat; corn meal; hominy; wheaten and graham grits; rolled rye and oats; granose; cerealin; macaroni with toasted bread-crumbs; farina, boiled with milk; milkine; horlick's or mellin's food. _vegetables_: spinach; green peas; greens; lettuce; watercress; sweet corn; asparagus; celery; artichokes; baked tomatoes; cauliflower. _dessert_: baked, roasted or stewed apples; stewed pears or peaches; baked bananas; grapes; oranges; and most ripe fruits, if fresh. _beverages_: hot, cool or cold water an hour before meals. drink freely of the same during meal-time, but not to wash down food. drink also: cereal coffee; buttermilk; koumiss; fresh cider; bouillon. _avoid_: coffee; tea; milk; ice-water; cocoa; chocolate; malt liquors; spirituous liquors; sweet and effervescent wines; sugar; candies; foods containing much starch; rich soups; sauces and chowders; all fried foods; hot or fresh bread; griddle-cakes; doughnuts; veal; pork; liver; kidney; hashes; stews; pickled, canned, preserved and potted meats; turkey; goose; duck; sausage; salmon; salt mackerel; cabbage; radishes; cucumbers; cole-slaw; turnips: potatoes; beets; pastry; jellies; jams; nuts. chapter xxx. diet for constipation and obstipation. diet is too often a makeshift for ignorance, or it may be an aid until the cause of indigestion is removed; or if not curable, a compromise effected on the best possible terms for continued existence. we have found out the almost universal cause for constipation, obstipation and costiveness; therefore until you can have the proper local treatment we suggest the following foodstuffs, trusting to the sufferer's judgment how much and how often to take the nourishment. coarse foods, stimulants and laxatives unduly excite the bowels. avoid them if possible. be regular in your habits as to meal-times; eat three times daily, and about an equal amount at each meal. you may take: _soup_: all kinds of meat and vegetable soup; broth; bouillon. reliable preparations of beef juice, jelly, etc. _fish_: all kinds, broiled or baked; raw oysters; doxsee's clam preparations. _meat_: boiled or roasted; poultry; game, etc. _bread_: graham; brown; whole wheat; corn; rye; ginger; shredded-wheat biscuit. _cereals_: wheaten grits; wheatena; granose; oatmeal porridge; milkine; horlick's and mellin's food. _vegetables_: cauliflower; spinach; beans; asparagus; carrots; onions; brussels sprouts; tomatoes; peas; celery; cabbage. vegetables should be especially well cooked to render them soft and easy of digestion. _salads_: may be eaten if dressed with a generous supply of olive oil. _dessert_: oranges; melons; prunes; tamarinds; figs; apples (raw or baked); pears; plums; peaches; cherries; raisins; stewed fruit; honey; blackberries; strawberries; huckleberries; bananas. some may find it advantageous to eat fruit before or between meals. _beverages_: water--pure spring water preferably; if this cannot be had, get, if possible, distilled water that has been aã«rated; buttermilk; fresh cider; beer; ale. mineral waters like hunyadi, etc., irritate the cause of constipation (proctitis) in a way similar to cathartic remedies. drink a tumbler or more of hot or cold water an hour before meals--preferably hot water. if the hot water be distasteful add a little salt. drink freely of water about the temperature of 60â° during the meals, but not for the purpose of emptying the mouth of food. on retiring at night and rising in the morning sip slowly from a quarter to half pint of water (hot or cold). in the morning be sure to rinse the mouth free of the accumulated mucus before drinking the water. the use of tea, chocolate, coffee and alcoholic drinks is so abused by those even who consider themselves temperate in their habits, that i recommend these beverages as remedies only in certain conditions of the system. about four pints of pure water (_i.e._, free from all salts or other foreign ingredients) should be imbibed in twenty-four hours. _avoid_: sweets; pastry of all kinds; puddings; rice; milk; cheese; new bread; nuts; fried foods; rich gravies; farina and sago puddings; salt meats; salt fish; veal; goose; liver; hard-boiled eggs; pork; tea; tobacco; spirituous liquors; uncooked strawberries and huckleberries. avoid also tomatoes and peaches when not fresh, as the acid generated by keeping them a few days is very irritating to an already inflamed bowel. avoid substances that would inflame the tissues or cause congestion of any organ of the body. if the tongue be coated avoid sugar, starchy foods and fresh milk. chapter xxxi. costiveness, diet, etc. take anything in the way of food which the unconsciously starved person can eat without the stomach and intestines protesting too much; any of the foods recommended for constipation, indigestion, diarrhea; and take yet more food if by so doing there is a gain in flesh, after exercising much patience as to time. irrigate the system by imbibing freely of hot and cold water at various periods of the day. good red wine mixed with the water drunk at meal-time may serve a good purpose in helping to enrich the blood. keep the pores of the skin open by bathing; and all the functions of the body active by exercise, massage, pure air, sunlight, rest, sleep and seasonable clothing. the large intestines should be kept clean by proper amounts of water injected into them. the local cause of all the trouble should be treated by a competent physician. and with all the efforts, continue the treatment long enough to accomplish some good and then a much longer time to get well. do not give up treatment under which you have improved if it requires one, two or three years to accomplish what you have so well started out to do. chapter xxxii. diet for diarrhea. a period marked by constipation, biliousness or poisons generated within or taken into the intestinal canal is often followed by diarrhea. mental excitement will induce it in some persons. more often man's early and most common malady, proctitis, is the direct or indirect cause. some forms of ulceration of the lower bowel induce diarrhea. chronic cases of diarrhea usually follow the decline of vitality marked by the symptom of costiveness, which means the interruption of all the functions of nutrition. the intestinal canal is then like a rubber tube with the contents hurried through it. the whole system is irritable as the result of an accumulation of secondary symptoms expressed by the word auto-intoxication. the food should be nutritious and non-irritating to the intestinal canal. reliance must be placed, in severe cases, on liquid foods and beverages. the more solid foods may be taken in limited quantity as the recovery progresses. in more acute cases it is well to stop all food for twelve or twenty-four hours. you may take: _liquid food and beverages_: drink, if possible, pure spring water. if this cannot be obtained, sterilize the water, or distil and aã«rate it; it must be pure and soft. better still: drink toastor rice-water; kefyr, four days old; koumiss; lactic-acid water; zoolak; egg lemonade; sterilized milk with one third lime-water; whortleberry wine; acorn cocoa; unfermented grape-juice. _soup_: chicken; mutton; clam; oyster broth; doxsee's clam-juice; bouillon; milkine; horlick's and mellin's food. _meat_: minced chicken; scraped beef; roast fowl; beef steak; fillet of beef; raw beef; sweetbread; raw oysters. _eggs_: lightly boiled, poached. _cereals and fruit_: grapes at all hours, eaten without seeds or skin; arrowroot; tapioca; sago; barley mush; macaroni; rice boiled with milk; milk toast; dry toast; crackers; junket; bread pudding; egg pudding, not sweetened; hasty pudding, with flour and milk; mashed potatoes. _avoid_: pork; veal; nuts; salt meats; fish; fried foods; sugary foods; fruits, cooked or raw; oatmeal; brown and graham bread; new bread; vegetables; and most soups. a final word to those to whom i have dedicated this book. it is very evident from the perusal of this work that the symptoms of proctitis, both general and local, proceed from no trifling disease; and also that the disease may have existed for a very long time, perhaps as much as twenty, forty or more years. during the greater part of its existence all sorts of medication have been tried to allay this or that annoying prominent symptom with a hope of a cure. at the congress of physicians that met in paris in 1900, one of the subjects discussed was chronic constipation and their "wise" conclusion was that man needed more grease, therefore they mourned the loss of the frying-pan. symptoms induced by proctitis in various parts of the body are often accompanied by painful local symptoms, called piles or a "touch of the piles." then local medication is added to the general treatment, and as usual matters go from bad to worse. physicians consulted have been honest and kind, but with all their advice the increasing troubles continue. your demands grow more pressing on your doctor and as a last resort he mentions a surgical operation for the removal of one or more painful local symptoms. the fright is sufficient in most cases to make the sufferer endure the ills he has rather than flee to others he knows not, even risking life itself. others more bold submit to an examination by the surgeon, which proves so painful at the time and causes so much subsequent suffering that they are now really content not to importune any more for help. a few in desperation make up their minds to have the local anal symptom removed regardless of the final result. thus millions of human beings have suffered and died and countless numbers are enduring the ills they have, not knowing of a rational and humane system of treatment; a treatment that not only removes the numerous annoying symptoms, but _the cause as well_; a system that will stand the test of time, _of common-sense_, _of constant investigation_ to know the _why_ and _wherefore_ of both disease and treatment. for over twenty years i have concerned myself with this and allied ailments, and have treated--without the use of the knife--all cases of piles, polypus, fissure, stricture, ulcerations, etc. at the present time physicians are writing me in this wise: "i want to take a course of instruction from you. i have performed some successful surgical operations on the rectum, but it is not profitable; the people will not submit to it." another writes: "your treatment of hemorrhoids has been brought to my notice by my friend and patient, mr. ----. the method you practise is certainly an ideal one and seems to have been most successful in your hands, and i would like to adopt it." to physicians and laymen interested, i will send, for twenty-five cents, my treatise on diseases of the anus and rectum (entitled _how to become strong_). it contains over 100 anatomical illustrations, and 125 testimonials, and forms, therefore, a valuable adjunct to this volume. all whose testimonials appear in the 64-page book suffered from proctitis to a greater or less extent and with the exception of a few all suffered from chronic constipation, indigestion, etc. surgeons usually desire strong and vigorous patients. the author asks merely for an intelligent patient, or for some one to direct the home attention necessary between treatments. this book, as well as the one entitled _how to become strong_, and the author's other printed instructions, are the result of his desire to make his patients intelligent on the subject of the disease and symptoms for which they seek his assistance. they truly cannot know too much for their own good in this regard; an ignorant patient can not do justice either to himself or to his physician. those who have tried all the fads and so-called cures in order to relieve their troubles will certainly appreciate what i have here presented for their study. with enlightenment comes the desire to set things right. so i have no appeal to make to the lazy: i shall leave them to their ills and their pills. and for those who appreciate the beauty of cleanliness, both external and internal, i shall write another book on that subject, including a prophecy for coming generations. eternal vigilance is the price we must pay if we would enjoy the highest physical, mental and spiritual expression of our personalities. thanking the indulgent reader who has read my description of intestinal ills, i advise him to rewrite it in his own organism, if not in printer's ink: the world will be better for it! intestinal ills. no. 1. chronic constipation and the use of the enema. "civilized" man is the victim, by inheritance from distant ancestors, of undesirable characteristics, traits, and tendencies. while, during the long process of evolution, some of the cruder features of the physical and mental traits have been refined or eliminated, the modern man still clings to certain habits inherited from his wholly animalistic days. even as the man of that day, so the man of to-day eats far too much and far too frequently. to the scientific eye, your capacious digestive apparatus is a psycho-physical exhibit of the racial proclivity to overeat. here, in this exhibit, the race's inordinate craving for food and drink, its gluttonous thought, have embodied themselves; and this exhibit, this apparatus, is accordingly not merely physical, but also psychical, for its sub-conscious outreach for "more and always more" is only too apparent. man's stomach and bowels are too much like those of a mere animal, and are the source of nine-tenths of his ills. all great consumers of foodstuffs, nature declares, should walk on all fours; if you will persist in walking on your hind legs, you will have to pay the penalty. you will, moreover, contract other habits not conducive to real animal health. and, as nature predicted, man's social customs to-day are out of all accord with gluttonous feeding; he, as well as his capacious bowels, suffers the consequences of his excessive feeding, and this suffering leads him to adopt artificial means for relief or escape. up-to-date civilization has constrained man to adopt a cooped-up existence, one that shuts out, to a great extent, sunshine and air; an existence, moreover, that involves but a limited amount of exercise. how, then, can it be otherwise than--gormand that he is--that he should fare ill with this gluttonous, mammoth digestive canal? man is not as yet more than half human, and he will not become truly human until he makes more use of the upper lobes of his brain, nor until the spiritual part of his nature becomes dominant. when that day dawns he will have a corresponding evolution of the physical body, especially of the gastro-intestinal canal. some one has sagely said that man's brain is a mere extension of his intestinal canal. well, possibly by and by the intestinal canal may become an extension of a spiritually awakened mind, with all its dominating influence over the physical body. surely the evolutional trend from animal to complete manhood may be aided by intelligent foresight as to bodily care and hygiene. cooped up like a canary bird, or penned up and fattening like a hog, with his enormous eating capacity and vast intestinal storage space, poor man has matters made worse by having his several orifices liable to inflammatory invasions. he does not seem able to escape from his enemies anywhere. the mucous membrane lining the orifices of the body is nothing more than the skin turned in to line canals for air, gases, liquids, and solids to pass in and out in order to keep up the physio-logical functions of the body. very rarely, indeed, do we find, from childhood to old age, the orifice of the intestinal sewer otherwise than chronically inflamed, the invasion extending, moreover, the whole length of the rectum for some distance into the sigmoid colon. it is no trifling matter to have the function of some thirty feet of the gastro-intestinal tract disturbed, especially of the large intestine--some five feet in length, two and a half inches in diameter in not a few sections. almost without exception, we find the lower portion of the intestinal sewer the seat of chronic inflammation that extends into the sigmoid colon; and, as an inevitable result of the inflammation, contraction more or less permanent has taken place in the circular and longitudinal muscular bands that form its structure. the constriction is especially severe at the junction of the rectum with the sigmoid colon, where it flexes upon itself in the region where the bore of the rectum is less. the comparative shutting up of the caliber of the upper end of the rectum and lower portion of the sigmoid colon occasions undue retention of the feces and gases which accumulate, and in accumulating dislocate various portions of the large intestine, thus forming pouches, sacks, reservoirs, prolapse, etc., which hold the products of putrefaction as well as the irritating, poisonous mucus thrown out from the inflamed tissue. i regard the occlusion of the upper portion of the rectum, and especially of the region involved in the flexure of the bowel, as the most usual seat and source of constipation. not so very long ago it was the custom to stretch the sphincter muscles for the "cure" of constipation; at the present time the "cure" is found in the valves of the middle lower portion of the rectum. the folly of these "cures" becomes apparent when we understand that the parts treated were neither the seat nor the source of constipation. i have always regarded great retention of feces in the rectum as _impaction_ in a delivery canal, due to contraction of the anal muscles, not as constipation, which can only take place in the temporary storage-place--the sigmoid flexure. the lower two-thirds of the rectum plays no part in constipation of the bowels. form a manikin, made out of very thin, soft rubber tubing, to represent the stomach and small and large intestine, holding the various parts in place with elastic bands, and cotton to represent fat. when all portions are properly and anatomically placed close the lower eight or ten inches of the manikin, representing the lower portion of the sigmoid colon, rectum, and anus, just as tightly as we should find it closed in sufferers from chronically acute proctitis and colitis. now insert at the stomach portion of the manikin a generous amount of man's usual mixture of foodstuffs and liquids, and repeat the supply three or four times during the day (without any previous attempts at cleansing), and then note the fermentative and putrefactive changes that take place; the ensuing bacterial poisons and the great volume of poisonous gases--all of which occasion squirming, twisting movements of the manikin as dislocations here and there occur, as pouches and reservoirs develop, as the walls become distended with gas and putrid substance; and then, time elapsing, the usual foodstuffs are added to the foul mass within! now, if there is any pity in your soul, you medical man, for the enfouled and deformed human manikin, you will want to wash it out with cleansing water before its structure comes to an untimely end. we medical men all know the numerous and grave symptoms exhibited by one or more organs of the body, or by all of them, from the persistent work of the deleterious gases and bacterial poisons on the system--a work going on for years, finally placing the victim beyond medical aid. all of us are agreed that the capacious gastro-intestinal canal should be clean. what, i submit, is the best means of keeping clean this long, large, tortuous, spacious, valved and flexed canal--a canal that disease has here and there pouched, dislocated, bagged, reservoired; a canal at whose lower end a great cesspool exists; that, like other portions of the gut, is never empty and clean--what is the best means but a flushing with copious amount of water? proctitis or colitis is a very serious disease; like a railroad injury, it is found, on examination, to be much worse than appearances at first indicated. a physician who prescribes for a case of chronic constipation or diarrhea without first examining the sufferer for proctitis and colitis, is either ignorant or does wilful harm to his patient and injury to his practice. the abominable, aboriginal and almost universal custom at the present time of giving some physic to "cleanse" the gastro-intestinal canal is in every respect a deplorable mistake for a conscientious doctor to make. many persons suffering from chronic constipation drink very little or no water. as a consequence, they are a sort of dirty, dried-up plant, with but little juice of life in them. others, again, equally unclean, or more so, take a moderate amount of fluid every day, and present a more or less roly-poly appearance, with considerable abdominal distention, due to malnutrition and gases. of course, their eyes, skin, tongue, breath, and lack of vim and vigor tell the story of a long process of self-poisoning, with every now and then the eventuation of a storm of foulness, called a bilious attack--meaning an overflow of filth. death often brings about a radical change in such poisoned bodies. now, what can a prescriber of a gastro-intestinal ejector expect to accomplish by disturbing the maleconomy of this apparatus? usually he expects that considerable trouble will ensue; consequently, he will add belladonna or some other soothing drug to mitigate the act of expulsion. the ejector (called laxative, purgative, cathartic) occasions irritation, which sets up twisting, writhing, rumbling of the bowels, accompanied with a shower of liquid into the canal (as tears fill the eyes from the effects of sand or a blow), which liquid mingles again with the putrid refuse materials, from which it had been recently absorbed, and, mingling, proceeds to fill up the normal and abnormal spaces just described, _to be again reabsorbed into the system_. oh, the foulness of it all! the spirits of the departed, as well as the still incarnate patients, demand of the healing art safe and sane hygienic methods of cure. _the enema, regularly and properly used, is the remedy par excellence._ those that suffer from chronic constipation are usually deficient in the quantity and quality of intestinal secretions. physic increases the depletion of the intestinal juices. of the watery secretion forced into the bowels, four-fifths are reabsorbed into the system, plus poisons and filth. the system soon becomes accustomed to the irritation of drugs, and requires an ever-increasing amount. these irritate and increase the chronic inflammation of the lower bowel, often to the extent of a discharge of blood. straining effort to induce defecation is injurious. the use of massage, of vibratory exercises, of electricity; the spraying of cold water on the abdomen, etc.,--none of them are calculated to remove or even to relieve the proctitis and colitis. the temperature of the water used for an enema should be about one hundred degrees. it should be taken at least twice daily, preferably on retiring at night and soon after breakfast, at regular times, if possible. such practice obviates the need of large injections. in beginning the use of the enema it is well to inject from a half to a pint of water, and expel it. this constitutes a preliminary injection. frequently it is desirable to take another preliminary injection before taking the large one, which latter is variously called "flushing the colon," "taking an enema," "taking an internal bath" or "a washout," etc. it is essential first to get rid of the feces and gases in the rectum, so that they be not sent back when you proceed to flush the colon. no. 2. objections to the use of enema answered. the privilege of raising objections belongs to the ignorant as well as to the intelligent. but the objector is under as great obligations to state his reasons as the advocate. the _first_ plausible objection to the use of the enema is that it is not natural. admitting this charge, i should say that, inasmuch as proctitis, colitis, and constipation are unnatural, the use of a preternatural or, in other words, a rational means to overcome the consequences of these diseases is imperative. the enema is such a means. can any one that suffers from proctitis, etc., have a natural stool? unnatural conditions require preternatural aids, as we all know. the injected water dilates the constricted portion of the gut and arouses a revulsive impulse to expel the invading water. in obeying this impulse the imprisoned feces, gases, etc., are ejected with the water. it may be unnatural to put water into the rectum, etc., but once there its expulsion from healthy bowels would be quite natural. no natural action can be expected from unhealthy bowels; they do the best they can under the circumstances. eye-glasses, false teeth, crutches, etc., are unnatural but invaluable aids, but no more so than is the enema as a means of relief from overloaded bowels. the enema, moreover, be it noted, not only aids the system by relieving it of its loads; it cleanses and soothes an organ that must be kept at work and perform its functions even when invaded by disease. surely it is unhygienic and irrational to ignore the valuable service of the enema in cases in which the bowels are in an unnatural condition. the _second_ objection is that the water will wash away the mucus from the mucous membrane of the bowels and leave them dry and parched, and thus apt to crack and break in two. i would remind the objector that, since about 75 per cent. of the normal feces is water, it seems strange that so great a quantity of water in contact with the mucous surface of the bowels should not also cause dryness. the integument of the body and that of the mucous membrane are similar in structure, yet whoever had a fear of producing dryness of the skin by much application of water? the mucous membrane is simply the skin turned inward; and since it is much more vascular it is less apt to become dry--if, indeed, its dryness were at all possible. the objector should also remember that the body is composed of over 80 per cent. of water--an organism not to be made dry or parched by the application of water to the skin or to the mucous membrane two or three times a day. the mucous membrane of the lower bowel is not unlike that of the mouth, throat, or stomach. do you realize how often the upper end of the intestinal canal is washed or bathed daily with liquids, soft and hard drinks, hot and cold, especially by those who have formed the drink habit instead of the enema habit? they have no fear of drying the mucous membrane thereby; but if you can instil this fear they will increase the quantity with pleasure. this second objection, being the result of too vivid an imagination and too little reflection, is a very nonsensical objection indeed. a _third_ objection is that if you begin the use of the enema you will have to continue its use; you can't stop, and, lo and behold! the enema habit is formed--a new habit in addition to the many habits civilized man is already carrying; the constipated habit, the physic habit, the sand, bran, sawdust-food habit, the muscular peristaltic habit, etc.--and with all these habits the poor victim of proctitis and intestinal foulness wonders that he is alive. usually the first symptom of proctitis is constipation, and for relief the enema habit should be formed and continued while the constipation remains. when the proper means are found to remove the intestinal inflammation--proctitis and colitis--then the constipation will disappear, and with its disappearance the enema habit can be discontinued. but let it be well noted that the enema is itself an aid in curing the cause, an aid superior to any other at our command. a cleanly habit ought not to be an objectionable one, especially in cases in which it is most needed to prevent toxic substances from entering the system. a _fourth_ objection is that after taking the first enema the constipation is worse. with many persons a certain amount of undue accumulation of feces will excite a sufficient muscular effort of the gut to force the dried mass through the proctitisand colitis-strictured bowels. this unnatural effort may occur once a day or once in two or three days, and has doubtless been a habit of many years' duration. to introduce a new order of conduct on the part of the bowels requires time. if the bowels have been in the habit of expelling feces in the morning, and an enema were taken the night before, there might be no desire to stool the next morning because of the fact that the bulk or accumulated mass of excrement was no longer there to create a vigorous call or impulse for defecation. but we have found the extent of local damage and reflex to the organs, and more especially the constant absorption of poisons into the system, due to the presence of feces. it is for this reason that the elimination of feces twice or thrice in twenty-four hours is advised. the condition for which an enema is used is one of disturbance and poison to the system. it is, therefore, a most unnatural condition. what is more rational, consequently, than to employ an "unnatural" yet not harmful means to bring about a more normal condition, one free from poisoning and irritating consequences? a _fifth_ objection is made by those who have as a symptom of proctitis a large development of pile tumors or hemorrhoids (distended mucous membrane). the objection is that at times these tumors or sacs prolapse very freely during the act of expelling the injected water. but this prolapse occurs in many cases whether water is used or not. a certain amount of anal irritation caused by the passage of feces occurs, causing contraction of the circular muscular tissue that forms the anal and rectal canal, also of the longitudinal muscular bands and the levator muscles of the organs. the enema lessens or entirely diminishes the irritation of passing feces, and the natural result is that the serum-filled sacs, called piles, and the tissue loosened by the inflammatory product will more readily prolapse during the act of defecating. it is simply a choice between irritation of the stool keeping the tissue up and no irritation permitting a prolapse. of course, if there be no expulsion of feces and water the stretched or dilated sacs may keep their places in the rectum. and then again, the enema may be used for quite a period, when all at once a large prolapse of sacculated mucous membrane occurs, and the enema is thought to be the cause of it. that this is not the cause, let it be remembered that in all cases of proctitis the chronic inflammation is apt to become subacute or acute, and that this intense engorgement and enlargement of the tissue with blood and the increased fever in the parts often result in prolapse at any time, especially at times of convulsive effort at evacuation. whatever follows the proper use of an enema, even though what follows be annoying, should not be blamed on the enema, for its action is most kindly, lessening as it does the irritation that otherwise would be more severe when the feces pass through a disease-constricted canal. the _sixth_ objection is that the use of the enema will weaken the bowels, which are already too "weak" to expel their contents. "atony, paralysis, fatty degeneration of the gut, are bad enough," say these objectors, "without having an enema increase their uselessness." diagnosis wrong and objection groundless. distend and contract an organ for a short time two or three times a day, and it will gain in strength from the exercise. every one knows that this is the case. what more gentle means of exercising the large intestines than by the enema? but the truth of the matter is that in all cases of proctitis and constipation the diseased portion of the gut is too active in its muscular movements, contracting spasmodically, as it does, at even the suggestion or suspicion of feces near it. every impulse of the bowels above the constricted section to force the feces down through the closed bore only intensifies the spasmodic action and increases the muscular obstruction, compelling the victim to resort to some one of the many drastic means of relief. the enema does no more than kindly to dilate the constricted region, which, when dilated, evokes a harmonious concerted action of all the nerves and muscles to pass along and down the burden of feces, which, without the aid of a flood of water, they had been incapable of moving, and would have had to leave to poison the system. the _seventh_ objection is quite naive: "inasmuch as the indians of this country had no use for the enema, why should we resort to it?" the all-sufficient answer to this objection is that the indians lived a natural life, while ours is artificial. much can be said on this point, but the reader is surely rational enough to follow out the distinction suggested. our lives are much more important than were the lives of the aborigines of this country, and our "demands of nature" are more exigent. if your life is of no greater value than theirs, for leisure's sake don't use the enema! you will be taking too much trouble. it really should seem that the cleanliness of the skin and mucous membrane, the care we take of our bodies, is an indication and measure of our sense of refinement. an ancient scripture hath it: "let those that are filthy, be filthy still." it all depends upon how you wish to be classed--with the filthy or the cleanly. the _eighth_ objection to be noted is the fear of "poking things" (points of instruments) "into the rectum." this looks like a real objection. no healthy nor even unhealthy organ, for that matter, should be "abused." and what seems more likely to cause it trouble than to poke a hard or soft rubber point or tube through its vent in opposition to its bent or inclination? still, the muscles of the vent are strong, and they soon accommodate themselves to the practice. their slight disinclination is not to be considered alongside of the relief and cure you effect by the use of the enema. have no fear that the point will occasion disease when intelligently used. always see to it that the point is scrupulously clean. those made of hard rubber or metal can be kept so without effort. soft rubber points are always foul and dangerous, especially after they are used a few times. a good rule is never to put a point higher in the bowel than is absolutely necessary. the _ninth_ objection seems serious. it is that in taking an enema the water escaping from the syringe point will injure the mucous membrane where the jet strikes. but on examination this objection falls to the ground, for it stands to reason the jet cannot directly hit the surface for more than a moment. immediately thereafter the accumulation of water will force the jet to spend its energy on the increasing volume, to lift it out of the way so that the continuous inflow may find room. but even were it possible for the jet to strike a definite section of the mucous membrane during the taking of the enema, it could do no harm provided the water be at the proper temperature. and this is true even if a hydrant pressure be used. not a few persons use the hydrant pressure of their houses in taking an enema. for a really successful flushing of the colon a considerable pressure is requisite to force the volume up and along a distance of five feet, especially when sitting upright. but it is folly to use a long syringe point, since it is like introducing one canal into another for the purpose of cleansing it. therefore, have no fear from the use of proper syringe points; the jet of water will not hurt the mucous membrane. my professional brethren at least ought to know that the idea of such harm is sheer nonsense. the _tenth_ objection to using an enema is in being obliged to use it from the fact of having such a disease as chronic inflammation of the rectum and colon. every victim hates to be compelled to do a thing, and the victim of proctitis and colitis is no exception to the rule. in fact, he is beginning to realize that unless he uses it his system will be poisoned by the absorption of the sewage waste. let the victim object to the disease that necessitates the use of the enema and he will shortly be well. then this objection to the use of the enema will indeed be the most important of all. the _eleventh_ objection, and the most ridiculous of all, is that it requires too much time to take the enema twice or thrice daily. i lose all patience with persons urging this objection. those that have little or no system with their daily duties seldom have time to do anything of importance. they suffer from "haphazarditis," a very difficult disease to cure, and they are in many cases hopeless. usually they are an uncleanly lot of people, full of good intentions, but their intentions though taken often, seldom operate as an antidote to foulness. their one sigh the livelong day is: "oh, could we be like birds that can stool while on the wing or on foot!" this feat of time-saving being hardly possible in the present incarnation and order of society, they content themselves with making a storehouse out of the intestinal canal for an indefinite length of time as they concern themselves with external affairs of work or sport. a sorry lot they are indeed when they are laid up for repairs. many doctors, i am sorry to say, encourage with a chuckle this foolish practice. "any time to stool you can manage to get, so that you stool at least once a day, or once in every two or three days; stool when it is normal for you to do so." this criminal advice just suits the sleepy, the lazy, or the "awfully busy." the american habit of doing things en masse, of handling things in large quantities or in bulk, has something to do with their don't care constipated habit. small evacuations two or three times a day seem too much like small business, which, of course, is a waste of precious time. wholesaling, laziness, lack of system, hurry, are the cause of good-for-nothingness of body and mind. _it should never be too much trouble to restore the lost impulse for stooling twice or thrice daily._ is it a small matter to have the main sewer of a city partly or entirely closed, or the main sewer pipe of a dwelling stopped up? think of the dire results, notwithstanding that the windows and doors remain wide open! the board of health would soon deal with the negligent official or landlord. with very few exceptions, "civilized" men, women, and children are negligent and niggardly caretakers of the human dwelling place--the marvellous body of man. "lack of time," "haven't the time," or "no time," is the excuse they give themselves and others. notwithstanding the numberless victims around them, none of these negligent and niggardly ones seem to get alarmed until the secondary symptoms, such as indigestion, gout, rheumatism, or disease of some vital organ, are sufficiently annoying to demand attention. but i have full faith in humanity. man does the best he knows how, as a general rule. but often he doesn't know how; he needs enlightening. the hints i have given will, i am confident, be considered and acted upon by all to whose attention they are brought, for by acting upon them, normal bodies and minds will result, and blessings attained heretofore considered impossible. normal health depends on right doing and being. eternal vigilance is the price to be paid for the attainment and maintenance of the goal of normal life and progress. eliminate all waste material from the body and all shifty vermin from the mind, and the millennium for all things in the universe will soon dawn. fourteen reasons why we should bathe internally as well as externally 1. because very few persons are free from chronic inflammation of the anus, rectum, and sigmoid flexure, which causes contraction of the caliber of the organs. 2. none escape self-poisoning from the gastro-intestinal canal. many are constantly being poisoned from the entrance of bacterial and other toxic substances into the system. 3. nine-tenths of the ills that afflict mankind have their origin in a foul digestive apparatus and a consequently poisoned body. 4. disease of the anus, rectum, and sigmoid flexure results in from two-thirds to three-fourths of the feces being daily absorbed into the system. 5. feces unduly retained become very foul or malodorous. if the feces of birds and domestic fowls and animals were as obnoxious as that usually ejected by man their discharges would require immediate removal from human neighborhoods. 6. man is the only creature that has formed the habit of making a fecal cesspool of his large intestine; hence his diseases of many varieties. there is nothing wholesome about him and he is quite destitute of vim, vigor, and push. the fecal poisoning of his parents is stamped upon him, and the unhygienic condition of his bowels makes matters worse. 7. man needs to form the habit of stooling as frequently as birds, fowls, and quadrupeds--at least as many times in twenty-four hours as he partakes of food. 8. making a reservoir of the lower bowels is not a time-saving habit, but, on the contrary, a breeder of many poisons, causing all sorts of acute and chronic diseases, which demand much time and attention, as countless numbers know to their sorrow. 9. you are a factor in the social and business world; then why not look, feel, and be your best by simply adopting internal hygienic measures? 10. by the use of the internal j.b.l. cascade bath you can secure two or three stools a day, as desired; and while you are preventing self-poisoning you are regaining a normal habit and natural health, which for so many years and generations have been denied you. do not longer perpetuate the dire results of a foul alimentary canal and consequently diseased body. 11. all desire to be strong and healthy, and many would add beauty of form and complexion, which is also commendable. this can be attained by preventing disease through hygienic attention and the proper use of water. 12. the gastro-intestinal canal is a physiological, moving food supply for the body, and, like any other vessel that has contained fermenting substances, it should be emptied and cleaned before a fresh supply is put into it. this is only a sensible, reasonable, and cleanly duty to one's self. 13. who can fear being made sick by adopting cleanly habits? you have perhaps tried all other means to keep well, and have failed; now try intestinal cleanliness--a method you should have thought of long ago. 14. every one desires to avoid surgery, the taking of numerous medicines, and the spending of money in that way--and they _can_ be avoided if you keep _clean_, both internally and externally. * * * * * you're not healthy unless you're clean inside and the one way to real internal cleanliness--by which you are protected against ninety per cent of all human ailments--is through _proper_ internal bathing, with plain antiseptic warm water. there is nothing unusual about this treatment--no drugs, no dieting--nothing but the correct application of nature's own cleanser. but only since the invention of the j.b.l. cascade has a means for _proper_ internal bathing existed. only one treatment is known for actually cleansing the colon without the aid of elaborate surgical apparatus. this is the internal bath by means of the j.b.l. cascade prof. metchnikoff, europe's leading authority on intestinal conditions, is quoted as saying that, if the colon and its poisonous contents were removable, people would live in good health to twice the present average of human life. dr. a. wilfred hall, ph.d., l.l.d., and w. e. forest, b.d., m.d., two world-famous authorities on internal bathing, are among the thousands of physicians who have given their hearty and active endorsement and support to the j.b.l. cascade treatment. fully half a million men and women and children now use this real boon to humanity--most of them in accordance with their doctor's orders. let dr. tyrrell advise you dr. tyrrell is always very glad of an opportunity to consult freely with anyone who writes him--and at no expense or obligation whatever. describe your case to him and he gives you his promise that you will learn facts about yourself which you will realize are of vital importance. you will also receive his book, "the what, the why, the way," which is a most interesting treatise on internal bathing. consultation with dr. tyrrell involves no obligation. charles a. tyrrell, m.d. 134 w. 65th street, new york if you suffer from rough, scaly, cracked skin if you value a good complexion dr. tyrrell's health soap effectually disposes of troubles. it is refreshing, purifying, invigorating among the necessities of life there is one to which few people pay the attention they ought, and that is soap. yet it is undoubtedly a most important matter, for the skin is a very delicate and sensitive organ, and the constant application of impure or inferior soaps injures its texture, and gives rise to numerous cutaneous troubles. most people are content, so long as it appeals to the eye and the sense of smell, without stopping to consider that perfumes may be employed to hide defects. dr. tyrrell has given this matter long and profound consideration and now offers to the public a soap that leaves nothing to be desired. it is not only absolutely free from any deleterious substance, but is a perfect antiseptic and healing soap. its use thoroughly cleanses and invigorates the skin, keeps it soft, flexible and healthy, and effectually prevents rough, cracked and scaly conditions. it is invaluable for tan, freckles, sunburn, etc., and is a perfect hygienic safeguard against cutaneous disorders. it is a positive pleasure to use it for the toilet or bath, as it leaves such a grateful, refreshing after-effect. as a shaving soap it is unequalled, absolutely preventing those disagreeable results

now offered to you. the j. b. l. catarrh remedy is one of those sterling specifics whose curative effects are quickly realized on the first trial. it is intended to be used in connection with the flushing treatment, and the two used in conjunction rarely fail to effect a cure. catarrh is first caused by inflammation of the membrane of the nasal cavities and air passages, which is followed by ulceration, when nature, in order to shelter this delicate tissue, and protect the olfactory nerves, throws a tough membrane over the ulcerated condition. flushing the colon lays the foundation for recovery, but the membrane must be removed, and for that purpose the j.b.l. catarrh remedy is without an equal. it is composed of several kinds of oils, and gently, but effectually, removes the membrane that nature has built over the inflamed parts, while its emollient character soothes and allays the inflammation. these drugs are not absorbed into the system, but act only locally. the most obstinate case will readily yield to this treatment. the price is one dollar per bottle, which, in view of its marvellous curative power, is a veritable gift, and with each bottle we furnish an inhaler specially manufactured for the purpose. two bottles will usually effect a cure--though one has been frequently known to do so in mild cases--but in the event of any one taking six bottles without being cured, we will forfeit one hundred dollars, now deposited in the lincoln trust co. of new york, if they can honestly make oath that they have faithfully used the remedy according to the directions, and have received no benefit from it. you cannot afford to neglect this opportunity of ridding yourself of this most distressing complaint, which, if neglected too often leads to consumption. _delays are dangerous._ charles a. tyrrell, m.d. formerly president of tyrrell's hygienic institute, 134 west 65th street new york the j.b.l. antiseptic tonic should always be used when introducing water into the intestines. the use of this preparation renders the water completely sterile unless it be notoriously impure. such water should never be used. but the antiseptic tonic possesses another important property which is most valuable in cases of constipation, for it acts as an admirable tonic on the muscular coat of the colon, strengthening it and restoring it to normal. for these reasons it is invaluable. owing to the importance of using the tonic, i have arranged to make it as inexpensive as possible and am prepared to furnish it (to users of the cascade only) in one pound air-proof cans at the price of $1.00; by mail twenty cents extra. you can buy this at your druggist and save mail charges. charles a. tyrrell, m.d. 134 west 65th street, new york city note:

london williams and norgate the university press, cambridge, u.s.a. 1913 preface in this little volume the author has endeavored to portray disease as life under conditions which differ from the usual. life embraces much that is unknown and in so far as disease is a condition of living things it too presents many problems which are insoluble with our present knowledge. fifty years ago the extent of the unknown, and at that time insoluble questions of disease, was much greater than at present, and the problems now are in many ways different from those in the past. no attempt has been made to simplify the subject by the presentation of theories as facts. the limitation as to space has prevented as full a consideration of the subject as would be desirable for clearness, but a fair division into the general and concrete phases of disease has been attempted. necessarily most attention has been given to the infectious diseases and their causes. this not only because these diseases are the most important but they are also the best known and give the simplest illustrations. the space given to the infectious diseases has allowed a merely cursory description of the organic diseases and such subjects as insanity and heredity. of the organic diseases most space has been devoted to disease of the heart. there is slight consideration of the environment and social conditions as causes of disease. very few authors are mentioned in the text and no bibliography is given. there is lack of literature dealing with the general aspects of disease; the book moreover is not written for physicians, and the list of investigators from whose work the knowledge of disease has been derived would be too long to cite. it has been assumed that the reader has some familiarity with elementary anatomy and physiology, and these subjects have been considered only as much as is necessary to set the scene for the drama. i am indebted to my friend, mr. w. r. thayer, for patiently enduring the reading of the manuscript and for many suggestions as to phrasing. contents chapter page chapter i definition of disease.--characteristics of living matter.--cells as the living

comprehensive. disease may be defined as "a change produced in living things in consequence of which they are no longer in harmony with their environment." it is evident that this conception of disease is inseparable from the idea of life, since only a living thing can become diseased. in any dead body there has been a preëxisting disease or injury, and, in consequence of the change produced, that particular form of activity which constitutes life has ceased. changes such as putrefaction take place in the dead body, but they are changes which would take place in any mass similarly constituted, and are not influenced by the fact that the mass was once living. disease may also be thought of as the negation of the normal. there is, however, in living things no definite type for the normal. an ideal normal type may be constructed by taking the average of a large number of individuals; but any single individual of the group will, to a greater or less extent, depart from it. no two individuals have been found in whom all the bertillon measurements agree. disease has reference to the individual; conditions which in one individual would be regarded as disease need not be so regarded in another. comparisons between health and disease, the normal and the abnormal, must be made not between the ideal normal and abnormal, but between what constitutes the normal or usual and the abnormal in a particular individual. the conception of disease is so inseparably associated with that of life that a brief review of the structure and properties of living things is necessary for the comprehension of the definition which has been given. living matter is subject to the laws which govern matter, and like matter of any other sort it is composed of atoms and molecules. there is no force inherent in living matter, no vital force independent of and differing from the cosmic forces; the energy which living matter gives off is counterbalanced by the energy which it receives. it undergoes constant change, and there is constant interchange with the environment. the molecules which compose it are constantly undergoing change in their number, kind and arrangement. atom groups as decomposition products are constantly given off from it, and in return it receives from without other atom groups with which it regenerates its substance or increases in amount. all definitions of life convey this idea of activity. herbert spencer says, "life is the continuous adjustment of internal relations to external conditions." the molecules of the substances forming the living material are large, complex and unstable, and as such they constantly tend to pass from the complex to the simple, from unstable to stable equilibrium. the elementary substances which form living material are known, but it has hitherto not been found possible artificially so to combine these substances that the resulting mass will exhibit those activities which we call the phenomena of life. the distinction between living and nonliving matter is manifest only when the sum of the activities of the living matter is considered; any single phenomenon of the living may appear also in the non-living material. probably the most distinguishing criterion of living matter is found in its individuality, which undoubtedly depends upon differences in structure, whether physical or chemical, between the different units. certain conditions are essential for the continued existence of living matter. it must be surrounded by a fluid or semi-fluid medium in order that there may be easy interchange with the environment. it must constantly receive from the outside a supply of energy in the form of food, and substances formed as the result of the intracellular chemical activity must be removed. in the case of many animals it seems as though the necessity of a fluid environment for living matter did not apply, for the superficial cells of the skin have no fluid around them; these cells, however, are dead, and serve merely a mechanical or protective purpose. all the living cells of the skin and all the cells beneath this have fluid around them. living matter occurs always in the form of small masses called "cells," which are the living units. the cells vary in form, structure and size, some being so large that they can be seen with the naked eye, while others are so small that they cannot be distinctly seen with the highest power of the microscope. the living thing or organism may be composed of a single cell or, in the case of the higher animals and plants, may be formed of great numbers of cells, those of a similar character being combined in masses to form organs such as the liver and brain. in each cell there is a differentiated area constituting a special structure, the nucleus, which contains a peculiar material called "chromatin." the nucleus has chiefly to do with the multiplication of the cell and contains the factors which determine heredity. the mass outside of the nucleus is termed "cytoplasm," and this may be homogeneous in appearance or may contain granules. on the outside there is a more or less definite cell membrane. it is generally believed that the cell material has a semi-fluid or gelatinous consistency and is contained within an intracellular meshwork. it is an extraordinarily complex mass, whether regarded from a chemical or physical point of view. (fig. 1.) [illustration: fig. 1.--diagram of cell. 1. cell membrane. 2. cell substance or cytoplasm. 3. nucleus. 4. nuclear membrane. 5. nucleolus.] a simple conception of health and disease can be arrived at by the study of these conditions in a unicellular animal directly under a microscope, the animal being placed on a glass slide. for this purpose a small organism called "amoeba" (fig. 2), which is commonly present in freshwater ponds, may be used. this appears as a small mass, seemingly of gelatinous consistency with a clear outline, the exterior part homogeneous, the interior granular. the nucleus, which is seen with difficulty, appears as a small vesicle in the interior. many amoebæ show also in the interior a small clear space, the contractile vesicle which alternately contracts and expands, through which action the movement of the intracellular fluid is facilitated and waste products removed. the interior granules often change their position, showing that there is motion within the mass. the amoeba slowly moves along the surface of the glass by the extension of blunt processes formed from the clear outer portion which adhere to the surface and into which the interior granular mass flows. this movement does not take place by chance, but in definite directions, and may be influenced. the amoeba will move towards certain substances which may be placed in the fluid around it and away from others. in the water in which the amoebæ live there are usually other organisms, particularly bacteria, on which they feed. when such a bacterium comes in contact with an amoeba, it is taken into its body by becoming enclosed in processes which the amoeba sends out. the enclosed organism then lies in a small clear space in the amoeba, surrounded by fluid which has been shown to differ in its chemical reaction from the general fluid of the interior. this clear space, which may form at any point in the body, corresponds to a stomach in a higher animal and the fluid within it to the digestive fluid or gastric juice. after a time the enclosed organism disappears, it has undergone solution and is assimilated; that is, the substances of which its body was composed have been broken up, the molecules rearranged, and a part has been converted into the substance of the amoeba. if minute insoluble substances, such as particles of carmine, are placed in the water, these may also be taken up by the amoeba; but they undergo no change, and after a time they are cast out. under the microscope only the gross vital phenomena, motion of the mass, motion within the mass, the reception and disintegration of food particles, and the discharge of inert substances can be observed. the varied and active chemical changes which are taking place cannot be observed. [illustration: fig. 2.--amoeba. 1. nucleus. 2. contractile vesicle. 3. nutritive vacuole containing a bacillus.] up to the present it has been assumed that the environment of the amoeba is that to which it has become adapted and which is favorable to its existence. under these conditions its structure conforms to the type of the species, as do also the phenomena which it exhibits, and it can assimilate food, grow and multiply. if, during the observation, a small crystal of salt be placed in the fluid, changes almost instantly take place. motion ceases, the amoebæ appear to shrink into smaller compass, and they become more granular and opaque. if they remain a sufficiently long time in this fluid, they do not regain their usual condition when placed again in fresh water. none of the phenomena which characterized the living amoebæ appear: we say they are dead. after a time they begin to disintegrate, and the bacteria contained in the water and on which the amoebæ fed now invade their tissue and assist in the disintegration. by varying the duration of the exposure to the salt water or the amount of salt added, a point can be reached where some, but not all, of the amoebæ are destroyed. whether few or many survive depends upon the degree of injury produced. much the same phenomena can be produced by gradually heating the water in which the amoebæ are contained. it is even possible gradually to accustom such small organisms to an environment which would destroy them if suddenly subjected to it, but in the process of adaptation many individuals will have perished. it is evident from such an experiment that when a living organism is subject to an environment to which it has not become adapted and which is unfavorable, such alterations in its structure may be produced that it is incapable of living even when it is again returned to the conditions natural to it. such alterations of structure or injuries are called the _lesions_ of disease. we have seen that in certain individuals the injury was sufficient to inhibit for a time only the usual manifestations of life; these returned when the organism was removed from the unfavorable conditions, and with this or preceding it the organisms, if visibly altered, regained the usual form and structure. we may regard this as disease and recovery. in the disease there is both the injury or lesion and the derangement of vital activity dependent upon this. the cause of the disease acted on the organism from without, it was external to it. whether the injurious external conditions act as in this case by a change in the surrounding osmotic pressure, or by the destruction of ferments within the cell, or by the introduction into the cell of substances which form stable chemical union with certain of its constituents, and thus prevent chemical processes taking place which are necessary for life, the result is the same. the experiments with the amoebæ show also two of the most striking characteristics of living matter. 1. it is _adaptable_. under the influence of unusual conditions, alterations in structure and possibly in substance, may take place, in consequence of which the organisms under such external conditions may still exhibit the usual phenomena. the organism cannot adapt itself to such changes without undergoing change in structure, although there may be no evidence of such changes visible. this alteration of structure does not constitute a disease, provided the harmonious relation of the organism with the environment be not impaired. an individual without a liver should not be regarded as diseased, provided there can be such an internal adjustment that all of the vital phenomena could go on in the usual manner without the aid of this useful and frequently maligned organ. 2. it is _individual_. in the varying degrees of exposure to unfavorable conditions of a more serious nature some, but not all, of the organisms are destroyed; in the slight exposure, few; in the longer, many. unfavorable conditions which will destroy all individuals of a species exposed to them must be extremely rare.[1] there is no such individuality in non-living things. in a mass of sugar grains each grain shows just the same characteristics and reacts in exactly the same way as all the other grains of the mass. individuality, however expressed, is due to structural variation. it is almost impossible to conceive in the enormous complexity of living things that any two individuals, whether they be single cells or whether they be formed of cell masses, can be exactly the same. it is not necessary to assume in such individual differences that there be any variation in the amount and character of the component elements, but the individuality may be due to differences in the atomic or molecular arrangements. there are two forms of tartaric-acid crystals of precisely the same chemical formula, one of which reflects polarized light to the left, and the other to the right. all the left-sided crystals and all the right-sided are, however, precisely the same. the number of possible variations in the chemical structure of a substance so complex as is protoplasm is inconceivable. in no way is the individuality of living matter more strongly expressed than in the resistance to disease. the variation in the degree of resistance to an unfavorable environment is seen in every tale of shipwreck and exposure. in the most extensive epidemics certain individuals are spared; but here care must be exercised in interpreting the immunity, for there must be differences in the degree of exposure to the cause of the epidemic. it would not do to interpret the immunity to bullets in battle as due to any individual peculiarity, save possibly a tendency in certain individuals to remove the body from the vicinity of the bullets; in battle and in epidemics the factors of chance and of prudence enter. no other living organism is so resistant to changes in environment as is man, and to this resistance he owes his supremacy. by means of his intelligence he can change the environment. he is able to resist the action of cold by means of houses, fire and clothing; without such power of intelligent creation of the immediate environment the climatic area in which man could live would be very narrow. just as disease can be acquired by an unfavorable environment, man can so adjust his environment to an injury that harmony will result in spite of the injury. the environment which is necessary to compensate for an injury may become very narrow. for an individual with a badly working heart more and more restriction of the free life is necessary, until finally the only environment in which life is even tolerably harmonious is between blankets and within the walls of a room. the various conditions which may act on an organism producing the changes which are necessary for disease are manifold. lack of resistance to injury, incapacity for adaptation, whether it be due to a congenital defect or to an acquired condition, is not in itself a disease, but the disease is produced by the action on such an individual of external conditions which may be nothing more than those to which the individuals of the species are constantly subject and which produce no harm.

(_a_) simple or tubular gland, (_b_) compound or racemose gland.] all of the causes of disease act on the body from without, and it is important to understand the relations which the body of a highly developed organism such as man has with the world external to him. this relation is effected by means of the various surfaces of the body. on the outside is the skin [fig. 3], which surface is many times increased by the existence of glands and such appendages to the skin as the hair and nails. a gland, however complicated its structure, is nothing more than an extension of the surface into the tissue beneath [fig. 4]. in the course of embryonic development all glands are formed by an ingrowth of the surface. the cells which line the gland surface undergo a differentiation in structure which enables them to perform certain definite functions, to take up substances from the same source of supply and transform them. the largest gland on the external surface of the body is the mammary gland [fig. 5] in which milk is produced; there are two million small, tubular glands, the sweat glands, which produce a watery fluid which serves the purpose of cooling the body by evaporation; there are glands at the openings of the hairs which produce a fatty secretion which lubricates the hair and prevents drying, and many others. [illustration: fig. 5.--a section of the mammary gland. (_a_) the ducts of the gland, by which the milk secreted by the cells which line all the small openings, is conveyed to the nipple. all these openings are continuous with the surface of the skin. on each side of the large ducts is a vein filled with blood corpuscles.] [illustration: fig. 6.--photograph of a section of the lung of a mouse. _x x_ are the air tubes or bronchi which communicate with all of the small spaces. on the walls of the partitions there is a close network of blood vessels which are separated from the air in the spaces by a thin membrane.] the external surface passes into the interior of the body forming two surfaces, one of which, the intestinal canal, communicates in two places, at the mouth and anus, with the external surface; and the other, the genito-urinary surface, which communicates with the external surface at one place only. the surface of the intestinal canal is much greater in extent than the surface on the exterior, and finds enormous extensions in the lungs and in the great glands such as the liver and pancreas, which communicate with it by means of their ducts. the extent of surface within the lungs is estimated at ninety-eight square yards, which is due to the extensive infoldings of the surface [fig 6], just as a large surface of thin cloth can, by folding, be compressed into a small space. the intestinal canal from the mouth to the anus is thirty feet long, the circumference varies greatly, but an average circumference of three inches may safely be assumed, which would give between seven and eight square feet of surface, this being many times multiplied by adding the surfaces of the glands which are connected with it. a diagram of the microscopic structure of the intestinal wall shows how little appreciation of the extent of surface the examination with the naked eye gives [fig. 7]. by means of the intestinal canal food or substances necessary to provide the energy which the living tissue transforms are introduced. this food is liquefied and so altered by the action of the various fluids formed in the glands of the intestine and poured out on the surface, that it can pass into the interior of the body and become available for the living cells. various food residues representing either excess of material or material incapable of digestion remain in the intestine, and after undergoing various changes, putrefactive in character, pass from the anus as feces. [illustration: fig. 7.--a section of the small intestine to show the large extent of surface. (_a_) internal surface. the small finger-like projections are the villi, and between these are small depressions forming tubular glands.] by means of the lungs, which represent a part of the surface, the oxygen of the air, which is indispensable for the life of the cells, is taken into the body and carbonic acid removed. the interchange of gases is effected by the blood, which, enclosed in innumerable, small, thin-walled tubes, almost covers the surface, and comes in contact with the air within the lungs, taking from it oxygen and giving to it carbonic acid. the genito-urinary surface is the smallest of the surfaces. in the male (fig. 8,--27, 28, 30) this communicates with the general external surface by the small opening at the extremity of the penis, and in the female by the opening into the vagina. in its entirety it consists in a surface of wide extent, comprising in the male the urethra, a long canal which opens into the bladder, and is continuous with ducts that lead into the genital glands or testicles. the internal surface of the bladder is extended by means of two long tubes, the ureters, into the kidneys, and receives the fluid formed in these organs. in the female (fig 9) there is a shallow external orifice which is continued into the bladder by a short canal, the urethra, the remaining urinary surface being the same as in the male; the external opening also is extended into the short, wide tube of the vagina, which is continuous with the canal of the uterus. this canal is continued on both sides into the fallopian tubes or oviducts. there is thus in the female a more complete separation of the urinary and the genital surfaces than in the male. practically all of the waste material of the body which results from cell activity and is passed from the cells into the fluid about them is brought by the blood to the kidneys, and removed by these from the blood, leaving the body as urine.

but the connection with the surface is lost in further development and it becomes completely enclosed. connected with the central nervous mass, forming really a part of it and developing from it, are the nerves, which appear as white fibrous cords and after dividing and subdividing, are as extremely fine microscopic filaments distributed to all parts of the body. by means of the nerves all impressions are conveyed to the brain and spinal cord; all impulses from this, whether conscious or unconscious, are conveyed to the muscles and other parts. the brain is the sole organ of psychical life; by means of its activity the impressions of the external world conveyed to it through the sense organs are converted into consciousness. whatever consciousness is, and on this much has been written, it proceeds from or is associated with the activity of the brain cells just as truly as the secretion of gastric juice is due to the activity of the cells of the stomach. the activity of the nervous system is essential for extra-uterine life; life ceases by the cessation of circulation and respiration when either the whole or certain small areas of its tissue are destroyed. in intra-uterine life, with the narrow and unchanging environment of the fluid within the uterine cavity which encloses the foetus, life is compatible with the absence or rudimentary development of the nervous system. the foetus in this condition may be otherwise well developed, and it would be not a misuse of words to say that it was healthy, since it is adjusted to and in harmony with its narrow environment, but it would not be normal. the intra-uterine life of the unborn child, it must be remembered, is carried out by the transmission of energy from the mother to the foetus by means of the close relation between the maternal and foetal circulation. it is only when the free existence demands activities not necessary in intra-uterine life that existence without a central nervous system becomes impossible. it is essential in so complicated a structure as the body that some apparatus should exist to provide for the interchange of material. the innumerable cell units of the body must have material to provide energy, and useless material which results from their activity must be removed. a household might be almost as much embarrassed by the accumulation of garbage and ashes as by the absence of food and coal. the food, which is taken into the alimentary canal and converted by the digestive fluids into material more directly adapted to the uses of cells, must be conveyed to them. a supply of oxygen is essential for the life of the cells, and the supply which is given by respiration must be carried from the lungs to every cell of the body. all this is effected by the circulation of the blood, which takes place in the system of branching closed tubes in which the blood remains (fig. 11). certain of these tubes, the arteries, have strong and elastic walls and serve to convey and distribute the blood to the different organs and tissues. from the ultimate branches of the arteries the blood passes into a close network of tubes, the capillaries, which in enormous numbers are distributed in the tissues and have walls so thin that they allow fluid and gaseous interchange between their contents and the fluid around them to take place. the blood from the capillaries is then collected into a series of tubes, the veins, by which it is returned to the heart. this circulation is maintained by means of a pumping organ or heart, which receives the blood from the veins and by the contraction of its powerful walls forces this into the arteries, the direction of flow being determined as in a pump, by a system of valves. the waste products of cell life pass from the cells into the fluid about them, and are in part directly returned into the blood, but for the greater part pass into it indirectly through another set of vessels, the lymphatics. these are thin-walled tubes which originate in the tissues, and in which there is a constant flow towards the heart, maintained by the constant but varying pressure of the tissue around them, the direction of flow being maintained by numerous valves. the colorless fluid within these vessels is termed "lymph." at intervals along these tubes are small structures termed the lymph nodes, which essentially are filters, and strain out from the fluid substances which might work great injury if they passed into the blood. between the capillary vessels and the lymphatics is the tissue fluid, in which all the exchange takes place. it is constantly added to by the blood, and returns fluid to the blood and lymph; it gives material to the cells and receives material from them. [illustration: fig. 11.--a diagrammatic view of the blood vessels. an artery (_a_) opens into a system of capillaries, (_c_) and after passing through these collects into a vein (_b_). notice that the capillaries connect with other vascular territories at numerous points (_d_). if the artery (_a_) became closed the capillaries which it supplies could be filled by blood coming from other sources.] in addition to the strength and elasticity of the wall of the arteries, which enables them to resist the pressure of the blood, they have the power of varying their calibre by the contraction or expansion of their muscular walls. many of the organs of the body function discontinuously, periods of activity alternating with comparative repose; during the period of activity a greater blood supply is demanded, and is furnished by relaxation of the muscle fibres which allows the calibre to increase, and with this the blood flow becomes greater in amount. each part of the body regulates its supply of blood, the regulation being effected by means of nerves which control the tension of the muscle fibres. the circulation may be compared with an irrigation system in which the water supply of each particular field is regulated not by the engineer, but by an automatic device connected with the growing crop and responding to its demands. [illustration: fig. 12.--the various cells in the blood. (_a_) the red blood cells, single and forming a roll by adhering to one another; (_b_) different forms of the white blood cells; those marked "1" are the most numerous and are phagocytic for bacteria.] the blood consists of a fluid, the blood plasma, in which numerous cells are contained. the most numerous of these are small cup-shaped cells which contain a substance called _hæmoglobin_, to which the red color of the blood is due. there are five million of these cells in a cubic millimeter (a millimeter is .03937 of an inch), giving a total number for the average adult of twenty-five trillion. the surface area of all these, each being one thirty-three hundredth of an inch in diameter, is about thirty-three hundred square yards. the hæmoglobin which they contain combines in the lungs with the oxygen in the inspired air, and they give up this indispensable substance to the cells everywhere in the body. there are also eight thousand leucocytes or colorless cells in a cubic millimeter of blood, this giving a total number of four billion in the average adult, and these vary in character and in relative numbers (fig. 12). the most numerous of these are round and slightly larger than the red cells; they have a nucleus of peculiar shape and contain granules of a definite character. these cells serve an important part in infectious diseases in devouring and destroying parasites. they have power of active independent motion and somewhat resemble certain of the free living unicellular organisms. the blood plasma, when taken from the vessels, clots or passes from a fluid into a gelatinous or semi-solid condition, which is due to the formation within it of a network of fine threads termed fibrin. it is by means of the clotting of the blood that the escape of blood from ruptured vessels is arrested. several of the organs of the body, in addition to the formation of secretions which are discharged on the surfaces by means of their ducts, produce also substances which pass directly into the blood or lymph, and have an influence in stimulating or otherwise regulating the activity of other organs. there are also certain organs of glandular structure which are called the _ductless glands_; these are not connected with the surface and all their secretion passes into the blood. it is a part of recent knowledge that the substances produced in these glands are of great importance for the body, some of them even essential for the maintenance of life. in front of the neck is such an organ, the thyroid gland (fig. 8, 14). imperfect development or absence of this organ, or an inactive condition of it, produces in the child arrested growth and deficient mental development known as cretinism, and in the adult the same condition gives rise to mental deterioration, swelling of the skin, due to a greater content of water, and loss of hair. this deficiency in the production of thyroid secretion can be made good and the symptoms removed by feeding the patient with similar glands removed from animals. the very complex disease known as exophthalmic goitre, and shown by irregular and rapid action of the heart, protruding eyeballs and a variety of mental symptoms, is also associated with this gland, and occasioned not by a deficiency but by an excess or perversion of its secretion. adjoining the thyroid there are four small glands, the parathyroids, each about the size of a split pea. the removal of these glands in animals produces a condition resembling acute poisoning accompanied by spasmodic contraction of the muscles. a small glandular organ at the base of the brain, the pituitary body, produces a secretion, one of the most marked properties of which is a control of growth, particularly that of the bones. most cases of giantism, combined as they are with imperfect mentality, are due to disease of this gland. there are glands near the kidney which regulate the pressure of the blood in the arteries by causing contraction of their muscular walls. the sexual characteristics in the male and female are due to an internal secretion produced by the respective sexual glands which affects growth, body development and mentality. so is the body constituted. a series of surfaces, all connected, of enormous size, which enclose a large number of organs and tissues, the activities of which differ, but all are coördinated to serve the purposes of the organism as a whole. we should think of the body not as an assemblage of more or less independent entities, but as a single organism in which all parts are firmly knit together both in structure and in function, as are the components of a single cell. footnotes: [1] they do, however, take place, since within comparatively few years whole species have completely disappeared; for example, the great auk and the passenger pigeon. in these cases it is not known what part disease played in the destruction. [2] a tissue represents an aggregate of similar cells with the intercellular substances in relation with these as connective tissue, muscular tissue, etc. where such cell aggregates are localized and where the cells are arranged in structures having definite form and size and performing a definite function, it is customary to designate such structures as organs, as the brain, liver, etc. chapter ii no sharp line of demarkation between health and disease.--the functional nutritive and formative activities of cells.--destruction and repair constant processes in living matter.--injuries to the body.--the effect of heat.--the action of poisons.--the lesions of disease.--repair.--the laws governing repair.--relation of repair to complexity of structure and age.--the reserve force of the body.-compensatory processes in the body.--old age.--the diminution of resistance to the effect of the environment a prominent factor in old age.--death.--how brought about.--changes in the body after death.-the recognition of death. there is no sharp line separating health from disease; changes in the tissues of the same nature, or closely akin to those which are found in disease, are constantly occurring in a state of health. the importance of parasites in causing disease has led to the conception of disease as almost synonymous with parasitism; but it must be remembered that the presence of parasites living at the expense of the body is perfectly consistent with a state of health. degeneration, decay and parasitism only become disease factors when the conditions produced by them interfere with the life which is the normal or usual for the individual concerned. all the changes which take place in the cells are of great importance in conditions of both health and disease, for life consists in coördinated cell activity. the activities of the cells can be divided into those which are nutritive, those which are functional and those which are formative. in the functional activity the cell gives off energy, this loss being made good by the receipt of new energy in the form of nutritive material with which the cell renews itself. in certain cells an exact balance seems to be maintained, but in those cells whose activity is periodic function takes place at the expense of the cell substance, the loss being restored by nutrition during the period of repose. this is shown particularly well in the case of the nerve cells (fig. 13). both the functional and nutritive activity can be greatly stimulated, but they must balance; otherwise the condition is that of disease. [illustration: fig 13.--nerve cells of an english sparrow (_a_) cells after a day's full activity, (_b_) cells after a night's repose. in (_a_) the cells and nuclei are shrunken and the smaller clear spaces in the cells are smaller and less evident than in (_b_). (hodge)] the formative activity of cells is also essential to the normal state. destruction of cells is constantly taking place in the body, and more rapidly in certain tissues than in others. dried and dead cells are constantly and in great numbers thrown off from the surface of the skin: such epidermic appendages as the hair and nails grow and are removed, millions of cells are represented in the beard which is daily removed. cells are constantly being destroyed on the intestinal surface and in the glands. there is an enormous destruction of the blood cells constantly taking place, certain essential pigments, as that of the bile, being formed from the hæmoglobin which the red blood corpuscles contain and which becomes available on their destruction. all such loss of cells must be made good by the formation of new ones and, as in the case of the nutritive and functional activity, the loss and renewal must balance. the formative activity of cells is of great importance, for it is by means of this that wounds heal and diseases are recovered from. this constant destruction and renewal of the body is well known, and it is no doubt this which has given rise to the belief, widely held, that the body renews itself in seven years and that the changes impressed upon it by vaccination endure for this period only. the truth is that the destruction and renewal of most tissues in the body takes place in a much shorter interval, and, as we shall see, this has nothing to do with the changes concerned in vaccination. all these activities of the cells vary in different individuals, in different parts and at different ages. the lesions or injuries of the body which form so prominent a part of disease vary in kind, degree and situation, depending upon the character of the injurious agent, the duration of its action and the character of the tissue affected. the most obvious injuries are those produced by violence. by a cut, blood vessels are severed, the relations of tissues disturbed, and at the gaping edges of the wound the tissue usually protected by the skin is exposed to the air, resulting in destruction of the cells contained in a thin layer of the surface. the discoloration and swelling of the skin following a blow is due to rupture of vessels and escape of blood and fluid, and further injury may result from the interruption of the circulation. by the application of heat the tissue may be charred and the albumen of the blood and tissue fluids coagulated. living cells are very susceptible to the action of heat, a temperature of 130 degrees being the thermal death point, and even lower temperatures are fatal when their action is prolonged. the action of the heat may produce definite coagulation of the fluid within the cells in the same way that the white of an egg is coagulated. certain of the albumens of the body coagulate at a much lower temperature than the white of the egg (as the myosin, one of the albumens of the muscle which coagulates at 115° f., egg white coagulating at 158° f.), and in addition to such coagulation or without it the ferments within the cell and to the action of which cellular activity is due may be destroyed. in diseases due to parasites, the parasite produces a change in the tissue in its immediate vicinity often so great as to result in the death of the cells. the most general direct cause of lesions is toxic or poisonous substances, either introduced from without or formed in the body. in the case of the parasitic diseases the mere presence of the parasite in the body produces little or no harm, the injury being caused by poisons which it produces, and which act both locally in the vicinity of the parasite and at a distance, being absorbed and entering the blood stream. how certain of the poisonous substances act is easy to see. strong caustics act by coagulating the albumen, or by the withdrawal of water from the cell. other poisons act by forming stable chemical compounds with certain of the cell constituents and thereby preventing the usual chemical processes from taking place. death from the inhalation of illuminating gas is due to the carbon monoxide contained in this, forming a firm chemical union with the hæmoglobin of the red corpuscles so that the function of these as oxygen carriers is stopped. in order that most poisons may act, it is essential that they enter into the cell, and they cannot do this unless they are able to combine chemically with certain of the cell constituents. to this is due the selective action of many poisons. morphine, for example, acts chiefly on the cells of the brain; strychnine acts on the cells of the spinal cord which excite motion and thus causes the characteristic muscular spasm. the poisonous substances produced by bacteria, as in the case of diphtheria, act on certain of the organs only. different animal species owe their immunity to certain poisons to their cells being so constituted that a poison cannot gain entrance into them; pigeons, for example, cannot be poisoned by morphia. individual variations play an important part also; thus, shellfish are poisonous for certain individuals and not so for others. owing to the variability of living structures a substance may be poisonous at one time and not at another, as the following example shows. a man, very fond of crab meat, was once violently poisoned after eating crabs, being at that time seemingly in his usual state of health, and no illness resulted in others who had partaken of the same crabs. two months later a hearty meal of crabs produced no ill result. there are also individuals so constituted that so simple a food as the egg is for them an active poison. the lesions produced by the action of injurious conditions are usually so distinctive in situation and character that by the examination of the body after death the cause of death can be ascertained. the lesions of diseases may be very obvious to the naked eye, or in other cases only the most careful microscopic examination can detect even the presence of alterations. in the case of poisons the capacity of the cell for adaptation to unusual conditions is of great importance. it is probable that certain changes take place within the cells, owing to which the function can be continued in spite of the unusual conditions which the presence of the poison brings about. it is in this way that the habitual use of such poisons as morphine, alcohol and tobacco, to speak only of those best known, is tolerated. the cell life can become so accustomed to the presence of poisons that the cell activities may suffer in their absence. _repair_ of the injuries which the body receives is effected in a variety of ways. we do not know how intracellular repair takes place, but most probably the cells get rid of the injured areas either by ejecting them, or chemical changes are produced in the altered cell substance breaking up and recombining the molecules. when single cells are destroyed, the loss is made good by new formation of cells, the cell loss stimulating the formative activity of the cells in the vicinity. the body maintains a cell and tissue equilibrium, and a loss is in most cases repaired. the blood fluid lost in a hæmorrhage is quickly restored by a withdrawal of the fluid from the tissues into the blood, but the cells lost are restored by new formation of cells in the blood-forming organs. the blood cells are all formed in bone marrow and in the lymph nodes, and not from the cells which circulate in the blood, and the stimulus to new cell formation which the loss of blood brings about affects this remote tissue. in general, repair takes place most easily in tissues of a simple character, and where there is the least differentiation of cell structure for the purposes of function. a high degree of function in which the cell produces material of a complex character necessitates a complex chemical apparatus to carry this out, and a complicated mechanism is formed less easily than a simple one. in certain tissues the cells have become so highly differentiated that all formative activity is lost. such is the case in the nerve cells of the brain and spinal cord, a loss in which tissue is never repaired by the formation of new cells; and in the muscles the same is true. the least differentiation is seen in those cells which serve the purpose of mechanical protection only, as the cells of the skin, and in these the formative activity is very great. not only must the usual loss be supplied, but we are all conscious of slight injuries of the surface which are quickly repaired. repair, other things being equal, takes place more easily in the young than in the old. new formation of cells goes on with great rapidity in intra-uterine life, the child, beginning its existence as a single cell one two hundred and fiftieth of an inch in diameter, attains in nine months a weight of seven pounds. the only similar rapidity of cell formation is seen in certain tumors; although the body may add a greater amount of weight and in a shorter time, by deposit of fat, this in but slight measure represents a new formation of tissue, but is merely a storage of food material in cells. the remarkable repair and even the new formation of entire parts of the body in the tadpole will not take place in the completely developed frog. repair will also take place the more readily the less complicated is the architectural structure of the part affected. when a series of tissues variously and closely related to one another enter into the structure of an organ, there may be new formation of cells; but when the loss involves more than this, the complicated architectural structure will not be completely replaced. a brick which has been knocked out of a building can be easily replaced, but the renewal of an area of the wall is more difficult. in the kidney, for example, the destruction of single cells is quickly made good by new cell formation, but the loss of an area of tissue is never restored. in the liver, on the other hand, which is of much simpler construction, large areas of tissue can be newly formed. for the formation of new cells in a part there must be a sufficient amount of formative material; then the circulation of the blood becomes more active, more blood being brought to the part by dilatation of the vessels supplying it. repair after a loss can be perfect or imperfect. the tissue lost can be restored so perfectly that no trace of an injury remains; but when the loss has been extensive, and in a tissue of complex structure, complete restoration does not take place and a less perfect tissue is formed which is called a scar. examination of the skin in almost anyone will show some such scars which have resulted from wounds. they are also found in the internal organs of the body as the result of injuries which have healed. the scar represents a very imperfect repair. in the skin, for example, the scar tissue never contains such complicated apparatus as hair and sweat glands; the white area is composed of an imperfectly vascularized fibrous tissue which is covered with a modified epidermis. the scar is less resistant than the normal tissue, injury takes place more easily in it and heals with more difficulty. loss brought about by the injuries of disease can be compensated for, even when the healing is imperfect, by increased function of similar tissue in the body. there always seems to be in the body under the usual conditions a reserve force, no tissue being worked to its full capacity. meltzer has compared the reserve force of the body to the factor of safety in mechanical construction. a bridge is constructed to sustain the weight of the usual traffic, but is in addition given strength to meet unusual and unforeseen demands. the stomach provides secretion to meet the usual demands of digestion, but can take care of an unusual amount of food. the work of the heart may be doubled by severe exertions, and it meets this demand by increased force and rapidity of contraction; and the same is true of the muscles attached to the skeleton. the constant exercise of this reserve force breaks down the adjustment. if the weight of the traffic over the bridge be constantly all that it can carry, there quickly comes a time when some slight and unforeseen increase of weight brings disaster. the conditions in the body are rather better than in the case of the bridge, because with the increased demand for activity the heart, for example, becomes larger and stronger, and reserve force rises with the load to be carried, but the ratio of reserve force is diminished. this discussion of injury and repair leads to the question of old age. old age, as such, should not be discussed in a book on disease, for it is not a disease; it is just as natural to grow old and to die as it is to be born. disease, however, differs in many respects in the old as compared with the young and renders some discussion of the condition necessary. changes are constantly taking place in the body with the advance of years, and in the embryo with the advance of days. in every period of life in the child, in the adult, in the middle-aged and in the old we meet with conditions which were not present at earlier periods. there is no definite period at which the changes which we are accustomed to regard as those of old age begin. this is true of both the external appearances of age and the internal changes. one individual may be fully as old, as far as is indicated by the changes of age, at fifty as another at eighty. with advancing age certain organs of the body atrophy; they become diminished in size, and the microscopic examination shows absence or diminished numbers of the cells which are peculiar to them. the most striking example of this is seen in the sexual glands of females, and, to a less degree, in those of the male. there is a small mass or glandular tissue at the root of the neck, the thymus, which gradually grows from birth and reaches its greatest size at the age of fifteen, when it begins slowly to atrophy and almost disappears at the age of forty. this is the gland which in the calf is known as the sweetbread and is a delicious and valued article of food. the tonsils, which in the child may be so large as to interfere with breathing and swallowing, have almost disappeared in the adult; and there are other such examples. in age atrophy is a prominent change. it is seen in the loss of the teeth, in the whitening and loss of the hair, in the thinning of the skin so that it more easily wrinkles, in the thinning and weakening of the muscles so that there is not only diminished force of muscular contraction, but weakening of the muscles of support. the back curves from the action of gravity, the strength of the support of the muscles at the back not counteracting the pull of the weight of the abdominal viscera in front. the bones become more porous and more brittle. the effect of atrophy is also seen in the diminution of all functions, and in loss of weight in individual organs. that the brain shares in the general atrophy is evident both anatomically and in function. mental activity is more sluggish, impressions are received with more difficulty, their accuracy may be impaired by accompanying changes in the sense organs, and the concepts formed from the impressions may differ from the usual. the slowness of mental action and the diminution in the range of mental activity excited by impressions, and the slowness of expression, may give a false idea of the value of the judgment expressed. the expression changes, the face becomes more impassive because the facial muscles no longer reflect the constant and ever changing impressions which the youthful sense organs convey to a youthful and active brain. that the young should ape the old, should seek to acquire the gravity of demeanor, to restrain the quick impulse, is not of advantage. loss of weight of the body as a whole is not so apparent, there being a tendency to fat formation owing to the non-use of fat or fat-forming material which is taken into the body. one of the most evident alterations is a general diminution in the fluid of the tissues, to which is chiefly due the lack of plumpness, the wrinkles of age. the facial appearance of age is given to an infant when, in consequence of a long-continued diarrhoea, the tissues become drained of fluid. every market-man knows that an old animal is not so available for food, the tissues are tougher, more fibrous, not so easily disintegrated by chewing. this is due to a relative increase in the connective tissue which binds all parts together and is represented in the white fibres of meat. senile atrophy is complex in its causes and modes of production. the atrophy affects different organs in different degree and shows great variation in situation, in degree and in progress. atrophic changes of the blood vessels are of great importance, for this affects the circulation on which the nutrition of all tissues depends. while there is undoubted progressive wear of all tissues, this becomes most evident in the case of the blood vessels of the body. it is rare that arteries which can be regarded as in all respects normal are found in individuals over forty, and these changes progress rapidly with advancing age. so striking and constant are these vascular changes that they seem almost in themselves sufficient to explain the senile changes, and this has been frequently expressed in the remark that age is determined not by years, but by the condition of the arteries. comparative studies show the falsity of this view, for animals which are but little or not at all subject to arterial disease show senile changes of much the same character as those found in man. there is another condition which must be considered in a study of causes of age. in the ordinary course of life slight injuries are constantly being received and more or less perfectly repaired. an infection which may but slightly affect the ordinary well-being of the individual may produce a considerable damage. excess or deficiency or improper food, occasional or continued use of alcohol and other poisons may lead to very definite lesions. repair after injury is rarely perfect, the repaired tissue is more susceptible to injury, and with advancing age there is constant diminution in the ease and perfection of repair. the effect of the sum of all these changes becomes operative: a vicious circle is established in which injury becomes progressively easier to acquire and repair constantly less perfect. there is some adjustment, however, in that the range of activities is diminished, the environment becomes narrower and the organism adapts its life to that environment which makes the least demands upon it. whether there is, entirely apart from all conditions affecting nutrition and the effect of injuries which disturb the usual cell activities, an actual senescence of the cells of the body is uncertain. in the presence of the many factors which influence the obvious diminution of cell activity in the old, it is impossible to say whether the loss of cell activity is intrinsic or extrinsic. the life of the plant cell seems to be immortal; it does not grow old. trees die owing to accidents or because the tree acquires in the course of its growth a mass of tissue in which there is little or no life, and which becomes the prey of parasites. the growing tissue of a tree is comprised in a thin layer below the bark, and the life of this may seemingly be indefinitely prolonged by placing it in a situation in which it escapes the action of accidental injuries and decay, as by grafting on young trees. where the nature of the dead wood is such that it is immune from parasites and decay, as in the case of the sequoias, life seems to be indefinitely prolonged. the growing branches of one of these trees, whose age has been estimated with seeming accuracy at six thousand years, are just as fresh and the tree produces its flowers and fruit in the same degree as a youthful brother of one thousand years. nor does old age supervene in the unicellular organisms. an amoeba assimilates, grows and multiplies just as long as the environment is favorable. old age in itself is seldom a cause of death. in rare cases in the very old a condition is found in which no change is present to which death can be attributed, all organs seem to share alike in the senescence. death is usually due to some of the accidents of life, a slight infection to which the less resistant body succumbs, or to the rupture of a weakened blood vessel in the brain, or to more advanced decay in some organ whose function is indispensable. the causes and conditions of age have been a fertile source for speculation. many of the hypotheses have been interesting, that of metschnikoff, for example, who finds as a dominating influence in causing senescence the absorption of toxic substances formed in the large intestine by certain bacteria. he further finds that the cells of the body which have phagocytic powers turn their activity against cells and tissues which have become weakened. there may be absorption of injurious substances from the intestines which the body in a vigorous condition is able to destroy or to counteract their influence, and these may be more operative in the weaker condition of the body in the old. phagocytes will remove cells which are dead and often cells which are superfluous in a part, but there is no evidence that this is ever other than a conservative process. since it is impossible to single out any one condition to which old age is due, the hypothesis of metschnikoff should have no more regard given it than the many other hypotheses which have been presented. death of the body as a whole takes place from the cessation of the action of the central nervous system or of the respiratory system or of the circulation. there are other organs of the body, such as the intestine, kidney, liver, whose function is essential for life, but death does not take place immediately on the cessation of their function. the functions of the heart, the brain and the lungs are intimately associated. oxygen is indispensable for the life of the tissues, and its supply is dependent upon the integrity of the three organs mentioned, which have been called the tripos of life. respiration is brought about by the stimulation of certain nerve cells in the brain, the most effective stimulus to these cells being a diminution of oxygen in the blood supplying them. these cells send out impulses to the muscles concerned in inspiration, the chest expands, and air is taken into the lungs. respiration is then a more complicated process than is the action of the heart, for its contraction, which causes the blood to circulate, is not immediately dependent upon extrinsic influences. death is usually more immediately due to failure of respiration than to failure of circulation, for the heart often continues beating for a time after respiration has ceased. thus, in cases of drowning and suffocation, by means of artificial respiration in which air is passively taken into and expelled from the lungs, giving oxygen to the blood, the heart may continue to beat and the circulation continue for hours after all evident signs of life and all sensation has ceased. by this general death is meant the death of the organism as a whole, but all parts of the body do not die at the same time. the muscles and nerves may react, the heart may be kept beating, and organs of the body when removed and supplied with blood will continue to function. certain tissues die early, and the first to succumb to the lack of oxygenated blood are the nerve cells of the brain. if respiration and circulation have ceased for as short a time as twelve minutes, life ceases in certain of these cells and cannot be restored. this is again an example of the greater vulnerability of the more highly differentiated structure in which all other forms of cell activity are subordinated to function. there are, however, pretty well authenticated cases of resuscitation after immersion in water for a longer period than twelve minutes, but these cases have not been carefully timed, and time under such conditions may seem longer than it actually is; and there is, moreover, the possibility of a slight gaseous interchange between the blood and the water in the lungs, as in the case of the fish which uses the water for an oxygen supply as the mammal does the air. there are also examples of apparent death or trances which have lasted longer, and the cases of fakirs who have been buried for prolonged periods and again restored to life. in these conditions, however, all the activities of the body are reduced to the utmost, and respiration and circulation, so feeble as to be imperceptible to ordinary observation, suffice to keep the cells living. with the cessation of life the body is subject to the unmodified action of its physical environment. there is no further production of heat and the body takes the temperature of the surroundings. the only exceptions are rare cases in which such active chemical changes take place in the dead body that heat is generated by chemical action. at a varying interval after death, usually within twelve hours, there is a general contraction and hardening of the muscles due to chemical changes, probably of the nature of coagulation, in them. this begins in the muscles of the head, extends to the extremities, and usually disappears in twenty-four hours. it is always most intense and most rapid in its onset when death is preceded by active muscular exertion. there have been cases of instantaneous death in battle where the body has remained in the position it held at the moment of death, this being due to the instantaneous onset of muscular rigidity. the blood remains fluid for a time after death and settles in the more dependent parts of the body, producing bluish red mottled discolorations. later the blood coagulates in the vessels. the body loses moisture by evaporation. drying of the surface takes place where the epidermis is thin, as over the transparent part of the eye and over areas deprived of epidermis. decomposition and putrefaction of the body due to bacterial action takes place. the bacteria ever present in the alimentary canal make their way from this into the dead tissue. certain of these bacteria produce gas which accumulates in the tissues and the body often swells enormously. a greenish discoloration appears, which is due to the union of the products of decomposition with the iron in the blood; this is more prominent over the abdomen and appears in lines along the course of the veins. the rapidity with which decomposition takes place varies, and is dependent upon many factors, such as the surrounding temperature, the nutrition of the body at the time of death, the cause of death. it is usually not difficult to recognize that a body is dead. in certain cases, however, the heart's action may be so feeble that no pulse is felt at the wrist, and the current of the expired air may not move a feather held to the nostril or cloud the surface of a mirror by the precipitation of moisture upon it. this condition, combined with unconsciousness and paralysis of all the voluntary muscles, may very closely simulate death. the only absolute evidence of death is given by such changes as loss of body heat, rigor mortis or stiffening of the muscles, coagulation of the blood and decomposition. chapter iii the growth of the body.--growth more rapid in embryonic period.--the coördination and regulation of growth.--tumors.--the growth of tumors compared with normal

also will grow, and the rapidity and character of growth and the maximum size of the crystal depends upon the character of the substance which forms the crystal. from the single cell or ovum formed by the union of the male and female sexual cells, growth is continuous until a size corresponding to the type of the species is attained. from this time onward growth is limited to the degree necessary to supply the constant loss of material which the body undergoes. the rapidity of the growth of the body and of its component parts differs at different ages, and becomes progressively less active from its beginning in the ovum until the adult type of the species is attained. as determined by the volume, the embryo increases more than ten thousand times in size during the first month of intra-uterine life. at birth the average weight is six and a half pounds; at the end of the first year eighteen and a half pounds, a gain of twelve pounds; at the end of the second year twenty-three pounds, a gain of four and a half pounds. the growth is coördinated, the size of the single organs bearing a definite ratio, which varies within slight limits, to the size of the body, a large individual having organs of corresponding size. knowing that the capacity of growth is one of the inherent properties of living matter, it is much easier to understand the continuance of growth than its cessation. it is impossible to avoid the conclusion that there is some internal mechanism of the body which controls and regulates growth. in the first chapter reference was made to organs producing substances which pass directly into the circulation; these substances act by control of the activities of other parts, stimulating or depressing or altering their function. two of these glands, the thymus, lying in front, where the neck joins the body and which attains its greatest size at puberty, and the pituitary body, placed beneath the brain but forming no part of it, have been shown by recent investigations to have a very definite relation to growth, especially the growth of the skeleton. the growth energy chiefly resides in the skeleton, and if the growing animal has a diet sufficient only to maintain the body weight, the skeleton will continue to grow at the expense of the other tissues, literally living upon the rest of the body. disease of the glands mentioned leading to an increase or diminution or alteration of their function may not only inhibit or unduly increase the growth of the skeleton, but may also interfere with the sexual development which accompanies the skeleton growth. the difficulties which arise in an endeavor to comprehend normal growth are greater when the growth of tumors is considered. a tumor is a mass of newly formed tissue which in structure, in growth, and the relations which it forms with adjoining tissues departs to a greater or less degree from the type of the tissue to which it is related in structure or from which it originates. it is an independent structure which, like a parasite, grows at the expense of the body, contributing nothing to it, and its capacity for growth is unlimited. a tumor cannot be considered as an organ, its activities not being coordinated with those of the body. a part of the body it certainly is, but in the household economy it is to be considered as a wild and lawless guest, not influenced by or conforming with the regulations of the household. the rapidity of growth varies; certain tumors for years increase but little in size, while others may be seen to increase from day to day. the growth is often intermittent, periods of great activity of growth alternating with periods of quiescence. the nutrition and growth of a tumor is only slightly influenced by the condition of nutrition of the bearer. its cells have a greater avidity for food than have those of the body, and, like the growing bones of an insufficiently fed animal, growth in some cases seems to take place at the expense of the body, the normal cells not obtaining sufficient nutriment to repair their waste. a tumor may be of any size: so small as to be invisible to the naked eye, or its weight may exceed that of the individual who bears it. the limitations to its growth are extrinsic and not intrinsic. there is no distinct color. certain tumors have color which depends upon the presence of a dark brown or black pigment within the cells. hæmorrhages within them are not infrequent, and they may be colored by the blood or by pigments formed from it. usually they have a gray color modified by their varying vascularity, or the cut surface may be mottled due to areas of cell degeneration. the consistency varies; some tumors are so soft that they can be pressed through a sieve, others are of stony hardness. there is no distinct shape, this being influenced by the nature of the tumor, the manner of growth and situation. when the tumor grows on or near a surface, it may project from this and be attached by a narrow band only; in the interior of the body it may be irregular in outline, round or lobular, the shape being influenced by many factors. tumors like the tissues of the normal body are nourished by the blood and contain blood vessels often in great numbers. a tumor arises by the cells of a part of the body beginning to grow and taking on the characteristics of a tumor. its growth is independent, the cells of the adjoining tissue taking no part in it. the tissue in the vicinity of the tumor is partly pushed aside by the mass, or the tumor grows into it and the tissue disappears as the tumor advances. the destruction of the surrounding tissue is brought about partly by the pressure which the tumor exerts, partly by the compression of the blood vessels or the blood supply of the organs is diverted to the tumor. the characteristics of a tumor are due to the cells which it contains (fig 14). these often become separated from the main mass and are carried by the blood into other parts of the body, where they grow and form tumors similar in character to the parent tumor. in the extraordinary capacity for growth possessed by tumor cells, they resemble vegetable rather than animal cells. there is no limit to the growth of a tumor save by the death of the individual who bears it, thus cutting off the supply of nutrition. the cells of tumors peculiar to man show a narrow range of adaptation. they will grow only in the body of the individual to whom the tumor belongs, and die when grafted on another individual. in the case of tumors which arise in animals, pieces of the tumor when grafted on another animal of the same species will grow, and in this way the growth capacity of the tumor cells has been estimated. thus, by transplanting a small section of a mouse tumor into other mice, the small transplanted fragments will in two weeks grow to the size of filberts, and each of these will furnish material to engraft upon ten mice. these new tumors are similar in character to the original tumor, and really represent parts of it in the same way that all the baldwin apples in the world are parts of the original tree which was found in baldwinville many years ago, and as all the concord grape vines are really parts of the original vine. it has been estimated that if all the growth capacity of this mouse tumor were availed of by the successive inoculation of other mice, a mass of tumor several times the diameter of the sun would grow in two years. the condition of the individual seems to exert no influence upon the growth of the tumor. growth may be as rapid when the bearer is in a condition of extreme emaciation as it is when the bearer is well nourished and robust. [illustration: fig 14.--photograph of a microscopic preparation from a cancer of the uterus. a large mass of cells is extending into the tissue of the uterus which is shown as the fibrous structure. such a cell mass penetrating into the tissue represents the real cancer, the tissue about the cell masses bear the blood vessels which nourish the tumor cells.] those tumors which grow rapidly and invade and destroy the surrounding tissue are called malignant tumors or cancers, but in a strict sense no tumor can be regarded as benign, for none can serve a useful purpose. a tumor after a period of slow growth can begin to grow rapidly. tumors may arise in any part of the body, but there are certain places of preference particularly for the more malignant tumors. these are places where the cells naturally have a marked power of growth, and especially where growth is intermittent as in the uterus and mammary gland. little is known in regard to the influence of inheritance on the formation of tumors. study of the tumors of mice show a slightly greater susceptibility to tumor formation in the progeny of mice who have developed tumors. studies of human families seem to show that heredity has a slight influence, but in the frequency of tumors such statistical evidence is of little value. the question of inheritance has much bearing on the origin of tumors. if the tumor is accidental and due entirely to extraneous causes, inheritance is not probable; but if there is some predisposition to tumor formation in certain individuals due to some peculiarity, then inheritance may exert an influence. the question as to whether tumors are an increasing cause of disease is equally difficult of solution. the mortality statistics, if taken at their face value, show an enormous increase in frequency; but there are many factors which must be considered and which render the decision difficult and doubtful. tumors are largely a prerogative of age, and the increased duration of life which preventive medicine has brought about brings more people into the age when tumors are more common. owing to the greater skill in the diagnosis of tumors, especially those of the internal organs, they are now recognized more frequently and more deaths are correctly ascribed to them. deaths from tumors were formerly often purposely concealed and attributed to some other cause. no age is immune to tumors. they may be present at birth or develop shortly afterwards. the age from five to twenty years is the most free from them, that from forty-five to sixty-five the most susceptible, particularly to the more malignant forms. a tumor is a local disease. the growing tissue of the tumor is the disease, and it is evident that if the entire tumor were removed the disease would be cured. this is the end sought by surgical interference, but notwithstanding seemingly thorough removal, the tumor often reappears after an interval of months or years. there are many conditions which may render the complete removal of a tumor difficult or impossible. it is often impossible to ascertain just how far the tumor cells have invaded the neighboring structures; the situation of the tumor may be such that an extended removal would injure organs which are essential for life, or at the time of removal the tumor cells may have been conveyed elsewhere by the blood or lymphatic vessels. successful removal depends mainly upon the length of time the tumor has been growing. at an early stage even the most malignant tumor may be successfully removed. it is evident from this how disastrous may be the neglect of proper surgical treatment of a tumor. the time may be very short between the first evidence of the presence of a tumor and the development of a condition which would render complete removal impossible. the effect of a tumor upon its bearer depends upon its character and situation. pain is very commonly present, and is due to the pressure which the growing tumor exerts upon the sensory nerves. pain may, however, not be present or appear only at the last. a condition of malnutrition and emaciation often results due to the passage into the blood of injurious substances formed in the tumor, or to the destruction of important organs by the growing tumor. the growth of a tumor in the intestine may obstruct or close the canal and thus interfere with nutrition. the cause or causes of tumors are unknown. we know that the tumor represents essentially an abnormal growth, and that this growth is due to new formation of cells. in certain cases the tumor repeats the structure of the organ or tissue in which it originates, in others it departs widely from this; always, however, its structure resembles structures found in the body at some period of life. the tumor cells, like all other cells of the body, grow by means of the nutriment which the body supplies; they have no intrinsic sources of energy. the great problem is what starts the cells to grow and why the growth differs from that of normal tissue, why it is not regulated and coördinated as are other forms of growth. when a small piece of the skin, for instance, is cut out growth as rapid as that in tumors takes place in the adjoining cells, _but it ceases when the loss is restored_. the same is true when a piece of the liver is removed. various hypotheses have been formed to explain the tumor, all of them of interest, and they have had great importance in that the attempt to prove or disprove the hypothesis by continued observation and experiment along definite lines has produced new knowledge. the various theories as to cause may be divided into three heads. the parasitic theory. this supposes that a living parasite invades the body, and by its presence excites the cells of certain tissues to grow in tumor form. it is known that active growth of the cells of the body can be excited in a number of ways, by chemical substances such as certain of the coal tar products, and that it often takes place under the influence of bacteria. it is further known that parasites can produce tumor-like growths in plants. the large, rough excrescences on the oaks are produced by a fly which lays its eggs in or beneath the bark, and the larva which develops from the egg secretes a substance which causes the cells about it to multiply, and a huge mass is formed which serves the developing insect for both food and protection. large tumor-like masses are formed on the roots and stalk of cabbages as the result of the invasion of the cells by a minute organism: the tumors of olive trees are due to a bacterium; the peculiar growths on cedar trees, the so-called "witches' brooms," are produced by a fungus, and there are many other such examples. these have many analogies with tumors in animals. under the stimulus of the parasite the cells seem to have unlimited growth capacity and a greater nutritive avidity than have the normal plant cells; the character of the mass produced differs as does the tumor, to a greater or less extent, from the normal growth; on the cedar, for instance, the "witches' broom" consists of a thick mass of foliage with small stems less green than the usual foliage, the leaves wider and not so closely applied to the stems. the entire plant suffers in its nutrition and a condition resembling tumor cachexia[1] is produced, and there are no fundamental differences between the plant and animal tumors. support has also been given to the parasitic theory by the discovery within tumor cells of bodies which were supposed to be a peculiar sort of parasite. if the truth of the parasitic theory could be proved, there would be justifiable expectation that the tumor disease might be controlled as are many of the parasitic diseases, but the hypothesis awaits the demonstration of its correctness. despite the study of tumors which is being actively pursued in many places and by the most skilled investigators, no parasites have been found in animal tumors; the objects previously described as parasites have been found not to be such. it is difficult to bring in accord with the parasitic theory the great variation in tumor structure, the relation of certain tumors, as the malignant tumors of the breast and uterus, with the age of the bearer, the congenital tumors which develop in intra-uterine life, and there are many other conditions which oppose the theory. the traumatic[2] theory. there is much in favor of this. in a certain number of cases tumors do develop at the site of injuries. the coincidence of injury and tumor is apt to be overestimated because of the strong tendency to connect succeeding events. tumors are not most common on those parts of the body which are most exposed to injury. they are rare, for instance, on the hands and feet, and very rarely do they appear at the site of wounds caused by surgical operations. for those tumors which develop in intra-uterine life it is difficult to assign injury as a cause. there does, however, seem to be a relation between tumors and injuries of a certain character. the natives of cashmere use in winter for purposes of heat a small charcoal stove which they bind on the front of the body; burns often result and tumors not infrequently develop at the site of such burns. injuries of tissue which are produced by the x-ray not infrequently result in tumor formation and years may elapse between the receipt of the injury and the development of the tumor. these x-ray injuries are of a peculiar character, their nature but imperfectly understood, and the injured tissues seem to have lost the capacity for perfect repair. in regard to the possible action of both injuries and parasites in causing tumors, the possibility that their effects on different individuals may not be the same must be considered. in addition to the trauma or the parasite which may be considered as extrinsic factors, there may be conditions of the body, intrinsic factors, which favor their action in tumor development. the peculiar tissue growth within the uterus called decidua, which occurs normally in pregnancy and serves to fasten the developing ovum to the inner lining of the uterus, may be produced experimentally. this growth depends upon two factors, an internal secretion derived from the ovary and the introduction into the uterus of a foreign body of some sort; in the case of pregnancy the developing embryo acts as the foreign body. it is not impossible that some variation in the complex relations which determine normal growth may be one factor, possibly the most important, in tumor formation. another theory is that the tumor is the result of imperfect embryonic development. the development of the child from the ovum is the result of a continued formation and differentiation of cells. a cell mass is first produced, and the cells in this differentiate into three layers called ectoderm, entoderm and mesoderm, from which the external and internal surfaces and the enclosed tissues respectively develop, and the different organs are produced by growth of the cells of certain areas of these layers. the embryonic theory assumes that in the course of embryonic development not all the cell material destined for the formation of individual organs is used up for this purpose, that certain of the embryonic cells become enclosed in the developing organs, they retain the embryonic capacity for growth and tumors arise from them. there is no doubt that something like this does take place. there is a relation between malformations due to imperfect development of the embryo and tumors, the two conditions occurring together too frequently to be regarded as mere coincidence. also tumors may occur in parts of the body in which there is no tissue capable of forming structures which may be present in the tumors. the theory, however, is not adequate, but it may be among the factors. the problems concerned in the nature and cause of tumors are the most important in medicine at the present time. no other form of disease causes a similar amount of suffering and anxiety, which often extends over years and makes a terrible drain on the sympathy and resources of the family. the only efficient treatment for tumors at the present time is removal by surgical operation, and the success of the operation is in direct ratio to the age of the tumor, the time which elapses from its beginning development. it is of the utmost importance that this should be generally recognized, and the facts relating to tumors become general knowledge. tumors form one of the most common causes of death (after the age of thirty-five one in every ten individuals dies of tumor); medical and surgical resources are, in many cases, powerless to afford relief and the tumor stands as a bar to the attainment of the utopia represented by a happy and comfortable old age, and a quiet passing. every possible resource should be placed at the disposal of the scientific investigation of the subject, for with knowledge will come power to relieve. footnotes: [1] by cachexia is understood a condition of malnutrition and emaciation which is usually accompanied by a pale sallow color of the skin. [2] by trauma is understood a wound or injury of any sort. chapter iv the reactions of the tissues of the body to injuries.--inflammation.-the changes in the blood in this.--the emigration of the corpuscles of the blood.--the evident changes in the injured part and the manner in which these are produced.--heat, redness, swelling and pain.--the production of blisters by sunburn.--the changes in the cells of an injured part.--the cells which migrate from the blood-vessels act as phagocytes.--the macrophages.--the microphages.--chemotropism.--the healing of inflammation.--the removal of the cause.--cell repair and new formation.--new formation of blood-vessels.--acute and chronic inflammation.--the apparently purposeful character of the changes in inflammation. injury and repair have already been briefly considered in their relation to the normal body and to old age; there are, however, certain phenomena included under the term inflammation which follow the more extensive injuries and demand a closer consideration than was given in chapter ii. these phenomena differ in degree and character; they are affected by the nature of the injurious agent and the intensity of its action, by the character of the tissue which is affected and by variations in individual resistance to injury. a blow which would have no effect upon the general surface of the body may produce serious results if it fall upon the eye, and less serious results for a robust than for a weak individual. most of the changes which take place after an injury and their sequence can be followed under the microscope. if the thin membrane between the toes of a living frog be placed under the microscope the blood vessels and the circulating blood can be distinctly seen in the thin tissue between the transparent surfaces. the arteries, the capillaries and veins can be distinguished, the arteries by the changing rapidity of the blood stream within them, there being a quickening of the flow corresponding with each contraction of the heart; the veins appear as large vessels in which the blood flows regularly (fig. 11). between the veins and arteries is a large number of capillaries with thin transparent walls and a diameter no greater than that of the single blood corpuscles; they receive the blood from the arteries and the flow in them is continuous. the white and red blood corpuscles can be distinguished, the red appearing as oval discs and the white as colorless spheres. in the arteries and veins the red corpuscles remain in the centre of the vessels appearing as a rapidly moving red core, and between this core and the wall of the vessels is a layer of clear fluid in which the white corpuscles move more slowly, often turning over and over as a ball rolls along the table. if, now, the web be injured by pricking it or placing some irritating substance upon it, a change takes place in the circulation. the arteries and the veins become dilated and the flow of blood more rapid, so rapid, indeed, that it is difficult to distinguish the single corpuscles. in a short while the rapidity of flow in the dilated vessels diminishes, becoming slower than the normal, and the separation between the red and white corpuscles is not so evident. in the slowly moving stream the white corpuscles move much more slowly than do the red, and hence accumulate in the vessels lining the inner surface and later become attached to this and cease to move forward. the attached corpuscles then begin to move as does an amoeba, sending out projections, some one of which penetrates the wall, and following this the corpuscles creep through. red corpuscles also pass out of the vessels, this taking place in the capillaries; the white corpuscles, on the other hand, pass through the small veins. not only do the white corpuscles pass through the vessels, but the blood fluid also passes out. the corpuscles which have passed into the tissue around the vessels are carried away by the outstreaming fluid, and the web becomes swollen from the increased amount of fluid which it contains. the injured area of the web is more sensitive than a corresponding uninjured area and the foot is more quickly moved if it be touched. if the injury has been very slight, observation of the area on the following day will show no change beyond a slight dilatation of the vessels and a great accumulation of cells in the tissue. everyone has experienced the effect of such changes as have been described in this simple experiment. an inflamed part on the surface of the body is redder than the normal, swollen, hot and painful. the usual red tinge of the skin is due to the red blood contained in the vessels, and the color is intensified when, owing to the dilatation, the vessels contain more blood. the inflamed area feels hot, and if the temperature be taken it may be two or three degrees warmer than a corresponding area. the increased heat is due to the richer circulation. heat is produced in the interior of the body chiefly in the muscles and great glands, and the increased afflux of blood brings more heat to the surface. a certain degree of swelling of the tissue is due to the dilatation of the vessels; but this is a negligible factor as compared with the effect of the presence of the fluid and cells of the exudate.[1] the fluid distends the tissue spaces, and it may pass from the tissue and accumulate on surfaces or in the large cavities within the body. the greatly increased discharge from the nose in a "cold in the head" is due to the exudation formed in the acutely inflamed tissue, and which readily passes through the thin epithelial covering. various degrees of inflammation of the skin may be produced by the action of the sun, the injury being due not to the heat but to the actinic rays. in a mild degree of exposure only redness and a strong sense of heat are produced, but in prolonged exposure an exudate is formed which causes the skin to swell and blisters to form, these being due to the exudate which passes through the lower layers of the cells of the epidermis and collects beneath the impervious upper layer, detaching this from its connections. if a small wad of cotton, soaked in strong ammonia, be placed on the skin and covered with a thimble and removed after two minutes, minute blisters of exudate slowly form at the spot. the pain in an inflamed part is due to a number of factors, but chiefly to the increased pressure upon the sensory nerves caused by the exudate. the pain varies so greatly in degree and character that parts which ordinarily have little sensation may become exquisitely painful when inflamed. the pain is usually greater when the affected part is dense and unyielding, as the membranes around bones and teeth. the pain is often intermittent, there being acute paroxysms synchronous with the pulse, this being due to momentary increase of pressure when more blood is forced into the part at each contraction of the heart. the pain may also be due to the direct action of an injurious substance upon the sensory nerves, as in the case of the sting of an insect where the pain is immediate and most intense before the exudate has begun to appear. when an inflamed area is examined, after twenty-four hours, by hardening the tissue in some of the fluids used for this purpose and cutting it into very thin slices by means of an instrument called a microtome, the microscope shows a series of changes which were not apparent on naked eye examination. the texture is looser, due to the exudate which has dilated all the spaces in the tissue. red and white corpuscles in varying numbers and proportions infiltrate the tissue; all the cells which belong to the part, even those forming the walls of the vessels, are swollen, the nuclei contain more chromatin, and the changes in the nuclei which indicate that the cells are multiplying appear. the blood vessels are dilated, and the part in every way gives the indication of a more active life within it. there are also evidences of the tissue injury which has called forth all the changes which we have considered. (fig. 15.) [illustration: fig. 15--a section of an inflamed lung showing the exudate within the air spaces. compare this with fig 6. fig 15 is from the human lung, in which the air spaces are much larger than in the mouse.] the microscopic examination of any normal tissue of the body shows within it a variable number of cells which have no intimate association with the structure of the part and do not seem to participate in its function. they are found in situations which indicate that these cells have power of active independent motion. in the inflamed tissue a greatly increased number of these cells is found, but they do not appear until the height of the process has passed, usually not before thirty-six or forty-eight hours after the injury has been received. the numbers present depend much upon the character of the agent which has produced the injury, and they may be more numerous than the ordinary leucocytes which migrate from the blood vessels. all these changes which an injured part undergoes are found when closely analyzed to be purposeful; that is, they are in accord with the conditions under which the living matter acts, and they seem to facilitate the operation of these conditions. it has been said that the life of the organism depends upon the coördinated activity of the living units or cells of which it is composed. the cells receive from the blood material for the purpose of function, for cell repair and renewal, and the products of waste must be removed. in the injury which has been produced in the tissue all the cells have suffered, some possibly displaced from their connections, others may have been completely destroyed, others have sustained varying degrees of injury. if the injury be of an infectious character, that is, produced by bacteria, these may be present in the part and continue to exert injury by the poisonous substances which they produce, or if the injury has been produced by the action of some other sort of poison, this may be present in concentrated form, or the injury may have been the result of the presence of a foreign body in the part. under these conditions, since the usual activities of the cells in the injured part will not suffice to restore the integrity of the tissue, repair and cell formation must be more active than usual, any injurious substances must be removed or such changes must take place in the tissue that the cell life adapts itself to new conditions.

(_a_) contains a number of round bacteria, and (_b_) similar bacteria arranged in chains, and (_c_) a number of rod-shaped bacteria (_d_) is a cell phagocyte or macrophage which contains five red blood corpuscles.] all life in the tissues depends upon the circulation of the blood. there is definite relation between the activity of cells and the blood supply; a part, for instance, which is in active function receives a greater supply of blood by means of dilatation of the arteries which supply it. if the body be exactly balanced longitudinally on a platform, reading or any exercise of the brain causes the head end to sink owing to the relatively greater amount of blood which the brain receives when in active function. the regulation of the blood supply is effected by means of nerves which act upon the muscular walls of the arteries causing, by the contraction or the relaxation of the muscle, diminution or dilatation of the calibre of the vessel. after injury the dilatation of the vessels with the greater afflux of blood to the part is the effect of the greatly increased cell activity, and is a necessity for this. in many forms of disease it has been found that by increasing the blood flow to a part and producing an active circulation in it, that recovery more readily takes place and many of the procedures which have been found useful in inflammation, such as hot applications, act by increasing the blood flow. so intimate is the association between cell activity, as shown in repair and new formation of cells, and the blood flow, that new blood vessels frequently develop by means of which the capacity for nutrition is still more increased. the cornea or transparent part of the eye contains no blood vessels, the cells which it contains being nourished by the tissue fluid which comes from the outside and circulates in small communicating spaces. if the centre of the cornea be injured, the cells of the blood vessels in the tissue around the cornea multiply and form new vessels which grow into the cornea and appear as a pink fringe around the periphery; when repair has taken place the newly formed vessels disappear. the exudate from the blood vessels in various ways assists in repair. an injurious substance in the tissue may be so diluted by the fluid that its action is minimized. a small crystal of salt is irritating to the eye, but a much greater amount of the same substance in dilute solution causes no irritation. the poisonous substances produced by bacteria are diluted and washed away from the part by the exudate. not only is there a greater amount of tissue fluid in the inflamed part, but the circulation of this is also increased, as is shown by comparing the outflow in the lymphatic vessels with the normal. the fluid exudate which has come from the blood and differs but slightly from the blood fluid exerts not only the purely physical action of removing and diluting injurious substances, but in many cases has a remarkable power, exercised particularly on bacterial poisons, of neutralizing poisons or so changing their character that they cease to be injurious. we have learned, chiefly from the work of metschnikoff, that those white corpuscles or leucocytes which migrate from the vessels in the greatest numbers have marked phagocytic properties, that is, they can devour other living things and thus destroy them just as do the amoebæ. in inflammations produced by bacteria there is a very active migration of these cells from the vessels; they accumulate in the tissue and devour the bacteria. they may be present in such masses as to form a dense wall around the bacteria, thus acting as a physical bar to their further extension. the other form of amoeboid cell, which metschnikoff calls the macrophage, has more feeble phagocytic action towards bacteria, and these are rarely found enclosed within them. it is chiefly by means of their activity that other sorts of substances are removed. they often contain dead cells or cell fragments, and when hæmorrhage takes place in a tissue they enclose and remove the granules of blood pigment which result. they often join together, forming connected masses, and surround such a foreign body as a hair, or a thread which the surgeon places in a wound to close it. they may destroy living cells, and do this seemingly when certain cells are in too great numbers and superfluous in a part, their action tending to restore the cell equilibrium. the foreign cells do even more than this: they themselves may be devoured by the growing cells of the tissue, seemingly being actuated by the same supreme idea of sacrifice which led buddha to give himself to the tigress. the explanation of most of the changes which take place in inflammation is obvious. it is a definite property of all living things that repair takes place after injury, and certain of the changes are only an accentuation of those which take place in the usual life; but others, such as the formation of the exudate, are unusual; not only is the outpouring of fluid greatly increased, but its character is changed. in the normal transudation[2] the substances on which the coagulation of the blood depends pass through the vessel wall to a very slight extent, but the exudate may contain the coagulable material in such amounts that it easily clots. the interchange between the fluid outside the vessels and the blood fluid takes place by means of filtration and osmosis. there is a greater pressure in the vessels than in the fluid outside of them, and the fluid filters through the wall as fluid filters through a thin membrane outside of the body. osmosis takes place when two fluids of different osmotic pressure are separated by animal membrane. difference in osmotic pressure is due to differences in molecular concentration, the greater the number of molecules the greater is the pressure, and the greater rapidity of flow is from the fluid of less pressure to the fluid of greater pressure. the molecular concentration of tissue and blood fluid is constantly being equalized by the process of osmosis. in the injured tissue the conditions are more favorable for the fluid of the blood to pass from the vessels: by filtration, because owing to the dilatation of the arteries there is increased amount of blood and greater pressure within the vessels, and the filtering membrane is also thinner because the same amount of membrane (here the wall of the vessel) must cover the larger surface produced by the dilatation. it is, moreover, very generally believed that there are minute openings in the walls of the capillaries, and these would become larger in the dilated vessel just as openings in a sheet of rubber become larger when this is stretched. osmosis towards the tissue is favored because, owing to destructive processes the molecular pressure in the injured area is increased; an injured tissue has been shown to take up fluid more readily outside of the body than a corresponding uninjured tissue. the slowing of the blood stream, in spite of the dilatation of the vessels, is due to the greater friction of the suspended corpuscles on the walls of the vessels. this is due to the loss from the blood of the outstreaming fluid and the relative increase in the number of corpuscles, added to by the unevenness of surface which the attached corpuscles produce. the wonderful migration of the leucocytes, which seems to show a conscious protective action on their part, takes place under the action of conditions which influence the movement of cells. when an actively moving amoeba is observed it is seen that the motion is not the result of chance, for it is influenced by conditions external to the organism; certain substances are found to attract the amoebae towards them and other substances to repel them. these influences or forces affecting the movements of organisms are known as _tropisms_, and play a large part in nature; the attraction of various organisms towards a source of light is known as _heliotropism_, and there are many other instances of such attraction. the leucocytes as free moving cells also come under the influence of such tropisms. when a small capillary tube having one end sealed is partially filled with the bacteria which produce abscess and placed beneath the skin it quickly becomes filled with leucocytes, these being attracted by the bacteria it contains. dead cells exert a similar attraction for the large phagocytes. such attraction is called _chemotropism_ and is supposed to be due in the cases mentioned, to the action of chemical substances such as are given off by the bacteria or the dead cells. the direction of motion is due to stimulation of that part of the body of the leucocyte which is towards the source of the stimulus. the presence in the injured part of bacteria or of injured and dead cells exerts an attraction for the leucocytes within the vessels causing their migration. when the centre of the cornea is injured, this tissue having no vessels, all the vascular phenomena take place in the white part of the eye immediately around the cornea, this becoming red and congested. the migration of leucocytes from the vessels takes place chiefly on the side towards the cornea, and the migrated cells make their way along the devious tracts of the communicating lymph spaces to the area of injury. the objection may be raised that it is difficult to think of a chemical substance produced in an injured area no larger than a millimeter, diffusing through the cornea and reaching the vessels outside this in such quantity and concentration as to affect their contents, nor has there been any evidence presented that definite chemical substances are produced in injured tissues; but there is no difficulty in view of the possibilities. it is not necessary to assume that an actual substance so diffuses itself, but the influence exerted may be thought of as a force, possibly some form of molecular motion, which is set in action at the area of injury and extends from this. no actual substance passes along a nerve when it conveys an impulse. we have left the injured area with an increased amount of fluid and cells within it, with the blood vessels dilated and with both cells and fluid streaming through their walls, and the cells belonging to the area actively repairing damages and multiplying. the process will continue as long as the cause which produces the injury continues to act, and will gradually cease with the discontinuance of this action, and this may be brought about in various ways. a foreign body may be mechanically removed, as when a thorn is plucked out; or bacteria may be destroyed by the leucocytes; or a poison, such as the sting of an insect, may be diluted by the exudate until it be no longer injurious, or it may be neutralized. even without the removal of the cause the power of adaptation will enable the life of the affected part to go on, less perfectly perhaps, in the new environment. the excess of fluid is removed by the outflow exceeding the inflow, or it may pass to some one of the surfaces of the body, or in other cases an incision favors its escape. the excess of cells is in part removed with the fluid, in part they disappear by undergoing solution and in part they are devoured by other cells. with the diminishing cell activity the blood vessels resume their usual calibre, and when the newly formed vessels become redundant they disappear by undergoing atrophy in the same way as other tissues which have become useless. when these changes take place rapidly the inflammation is said to be acute, and chronic when they take place slowly. chronic inflammation is more complex than is the acute, and there is more variation in the single conditions. the chronicity may be due to a number of conditions, as the persistence of a cause, or to incompleteness of repair which renders the part once affected more vulnerable, to such a degree even that the ordinary conditions to which it is subjected become injurious. a chronic inflammation may be little more than an almost continuous series of acute inflammations, with repair continuously less perfect. chronic imflammations are a prerogative of the old as compared with the young, of the weak rather than the strong. footnotes: [1] the term exudation is used to designate the passing of cells and fluid from the vessels in inflammation;

the majority of deaths are caused directly or indirectly by infection. no other diseases have been so much studied, and in no other department of science has knowledge been capable of such direct application in promoting the health, the efficiency and the happiness of man. this knowledge has added years to the average length of life, it has rendered possible such great engineering works as the panama canal, and has contributed to the food supply by making habitation possible over large and productive regions of the earth, formerly uninhabitable owing to the prevalence of disease. it is not too much to say that our modern civilization is dependent upon this knowledge. the massing of the people in large cities, the factory life, the much greater social life, which are all prominent features of modern civilization, would be difficult or impossible without control of the infectious diseases. the rapidity of communication and the increased general movement of people, which have developed in equal ratio with the massing, would serve to extend widely every local outbreak of infection. the principles underlying fermentation and putrefaction which have been applied with great economic advantage to the preservation of food were many of them developed in the course of the study of the infectious diseases. whether the development of the present civilization is for the ultimate advantage of man may perhaps be disputed, but medicine has made it possible. the infectious diseases appearing in the form of great epidemics have been important factors in determining historical events, for they have led to the defeat of armies, the fall of cities and of nations. war is properly regarded as one of the greatest evils that can afflict a nation, since it destroys men in the bloom of youth, at the age of greatest service, and brings sorrow and care and poverty to many. but the most potent factor in the losses of war is not the deaths in battle but the deaths from disease. if we designate the lives lost in battle, the killed and the wounded who die, as 1, the loss of the german army from disease in 1870-71 was 1.5, that of the russians in 1877-78 was 2.7, that of the french in mexico was 2.8, that of the french in the crimea 3.7, that of the english in egypt 4.2. the total loss of the german army in 1870-71 from wounds and disease was 43,182 officers and men, and this seems a small number compared with the 129,128 deaths from smallpox in the same period in prussia alone. in the spanish american war there were 20,178 cases of typhoid fever with 1,580 deaths. in the south african war there were in the british troops 31,118 cases of typhoid with 5,877 deaths, and 5,149 deaths from other diseases while the loss in battle was 7,582. the athenian plague which prevailed during the peloponnesian war, 431-405 b.c., not only caused the death of pericles, but according to thucydides a loss of 4,800 athenian soldiers, and brought about the downfall of the athenian hegemony in greece. in the crimean war between 1853-56, 16,000 english, 80,000 french and 800,000 russians died of typhus fever. the plague contributed as much as did the arms of the turks to the downfall of constantinople and the eastern empire in 1453. it was the plague which in 1348 overthrew siena from her proud position as one of the first of the italian cities and the rival of florence, and broke the city forever, leaving it as a phantom of its former glory and prosperity. the work on the great cathedral which had progressed for ten years was suspended, and when it was resumed it was upon a scale adjusted to the diminished wealth of the city, and the plan restricted to the present dimensions. as a little relief to the darkness the same plague saw the birth of the novel in the tales of boccaccio, which were related to a delighted audience of the women who had fled from the plague in florence to a rural retreat. the knowledge which has come from the study of infectious disease has served also to broaden our conception of disease and has created preventive medicine; it has linked more closely to medicine such sciences as zoölogy and botany; it has given birth to the sciences of bacteriology and protozoölogy and in a way has brought all sciences more closely together. above all it has made medicine scientific, and never has knowledge obtained been more quickening and stimulating to its pursuit. although the dimensions of this book forbid much reference to the historical development of a subject, some mention must still be made of the development of knowledge of the infectious diseases. it was early recognized that there were diseases which differed in character from those generally prevalent; large numbers of people were affected in the same way; the disease beginning with a few cases gradually increased in intensity until an acme was reached which prevailed for a time and the disease gradually disappeared. such diseases were attributed to changes in the air, to the influence of planets or to the action of offended gods. the priests and charlatans who sought to excuse their inability to treat epidemics successfully were quick to affirm supernatural causes. hippocrates (400 b.c.), with whom medicine may be said to begin, thought such diseases, even then called epidemics, were caused by the air; he says, "when many individuals are attacked by a disease at the same time, the cause must be sought in some agent which is common to all, something which everyone uses, and that is the air which must contain at this time something injurious." aristotle recognized that disease was often conveyed by contact, and varro (116-27 b.c.) advanced the idea that disease might be caused by minute organisms. he says, "certain minute organisms develop which the eye cannot see, and which being disseminated in the air enter into the body by means of the mouth and nostrils and give rise to serious ailments." in spite of this hypothesis, which has proved to be correct, the belief became general that epidemics were due to putrefaction of the air brought about by decaying animal bodies, (this explaining the frequent association of epidemics and wars,) by emanations from swamps, by periods of unusual heat, etc. with the continued study of epidemics the importance of contagion was recognized; it was found that epidemics differed in character and in the modes of extension. some seemed to extend by contact with the sick, and in others this seemed to play no part; it was further found impossible in many cases to show evidence of air contamination, and contamination of the air by putrefactive material did not always produce disease. most important was the recognition that single cases of diseases which often occurred in epidemic form might be present and no further extension follow; this led to the assumption in epidemics of the existence of some condition in addition to the cause, and which made the cause operative. in this way arose the theory of the epidemic constitution, a supposed peculiar condition of the body due to changes in the character of the air, or to the climate, or to changes in the interior of the earth as shown by earthquakes, or to the movements of planets; in consequence of this peculiar constitution there was a greater susceptibility to disease, but the direct cause might arise in the interior of the body or enter the body from without. the character of the disease which appeared in epidemic form, the "genius epidemicus," was determined not by differences in the intrinsic cause, but by the type of constitution which prevailed at that time. the first epidemic of cholera which visited europe in 1830-37 was for the most part referred to the existence of a peculiar epidemic constitution for which various causes were assigned. it was only when the second epidemic of this disease appeared in 1840 that the existence of some special virus or poison which entered the body was assumed. meanwhile, by the study of the material of disease knowledge was being slowly acquired which had much bearing on the causes. the first observations which tended to show that the causes were living were made by a learned jesuit, athanasius, in 1659. he found in milk, cheese, vinegar, decayed vegetables, and in the blood and secretions of cases of plague bodies, which he described as tiny worms and which he thought were due to putrefaction. he studied these objects with the simple lenses in use at that time, and there is little doubt that he did see certain of the larger organisms which are present in vinegar, cheese and decaying vegetables, and it is not impossible that he may have seen the animal and vegetable cells. the first description of bacteria with illustrations showing their forms was given by loewenhoeck, a linen dealer in amsterdam in 1675. the fineness of the linen being determined by the number of threads in a given area, it is necessary to examine it with a magnifying lens, and he succeeded in perfecting a simple lens with which objects smaller than had been seen up to that time became visible. it must be added that he was probably endowed with very unusual acuteness of vision. he found in a drop of water, in the fluid in the intestines of frogs and birds, and in his evacuations, objects of great minuteness which differed from each other in form and size and in the peculiar motion which some of them possessed. in the year 1683 he presented to the royal society of london a paper describing a certain minute organism which he found in the tartar of his teeth. after these observations of loewenhoeck became known to the world they quickly found application in disease, although the author had expressed himself very cautiously in this regard. the strongest exponent of the view of a living contagion was plenciz, 1762, a physician of vienna, basing his belief not only on the demonstration of minute organisms by loewenhoeck which he was able to verify, but on certain shrewdly conceived theoretical considerations. he was the first to recognize the specificity of the epidemic diseases, and argued from this that each disease must have a specific cause. "just as a certain plant comes from the seed of the same plant and not from any plant at will, so each contagious disease must be propagated from a similar disease and cannot be the result of any other disease." further he says, "it is necessary to assume that during the prevalence of an epidemic the contagious material undergoes an enormous increase, and this is compatible only with the assumption that it is a living substance." but as is so often the case, speculation ran far ahead of the observations on which it is based. there was a long gap between the observations of loewenhoeck and the theories of plenciz, justified as these have been by present knowledge. in the spirit of speculation which was dominant in europe and particularly in germany in the latter half of the eighteenth and the first half of the nineteenth centuries, hypotheses did not stimulate research, but led to further speculations. as late as 1820 ozanam expressed himself as follows: "many authors have written concerning the animal nature of the contagion of disease; many have assumed it to be developed from animal substance, and that it is itself animal and possesses the property of life. i shall not waste time in refuting these absurd hypotheses." the theory of a living contagion was too simple, and not sufficiently related to the problems of the universe to serve the medical philosophers. knowledge of the minute organisms was slowly accumulating. the first questions to be determined were as to their nature and origin. how were they produced? did they come from bodies of the same sort according to the general laws governing the production of living things, or did they arise spontaneously? a question which could not be solved by speculation but by experiment. the first experiments, by needham, 1745, pointed to the spontaneous origin of the organisms. he enclosed various substances in carefully sealed watch crystals from which the air was excluded, and found that animalculi appeared in the substance, and argued from this that they developed spontaneously. in 1769, spallanzani, a skilled experimental physiologist, in a brilliant series of experiments showed the imperfect character of needham's work and the fallacy of his conclusions. spallanzani placed fluids, which easily became putrid, in glass tubes, which he then hermetically sealed and boiled. he found that the fluid remained clear and unchanged; if, however, he broke the sealed point of such a tube and allowed the air to enter, putrefaction, or in some cases fermentation, of the contents took place. he concluded that boiling the substances destroyed the living germs which they contained, the sealed tubes prevented the air from entering, and when putrefaction or fermentation of the contents took place the organisms to which this was due, being contained in the air, entered from without. objection was made to the conclusions of spallanzani that heating the air in the closed tubes so changed its character as to prevent development of organisms in the contents. this objection was finally set aside by pasteur, who showed that it was not necessary to seal the end of the tube before boiling, but it could be closed by a plug of cotton wool, which mechanically removed the organisms from the air which entered the tube, or if the tube were bent in the shape of a _u_ and the end left open, organisms from the air could not pass into the tube against gravity when air movement within the tube was prevented by bending. the possibility of spontaneous generation cannot be denied, but that it takes place is against all human experience. it was not possible to attain any considerable knowledge of the bacteria discovered by loewenhoeck until more perfect instruments for studying them were devised. lenses for studying objects were used in remote antiquity, but the compound microscope in which the image made by the lens is further magnified was not discovered until 1605, and when first made was so imperfect that the best simple lenses gave clearer definition. with the betterment of the microscope, increasing the magnifying power and the sharpness of the image of the object seen, it became possible to classify the minute organisms according to size and form and to study the separate species. the microscope has now reached such a degree of perfection that objects smaller than one one hundred thousandth of an inch in diameter can be clearly seen and photographed. great impetus was given to the biological investigation of disease by the discoveries which led to the formulation of the cell theory in 1840 and the brilliant work of pasteur on fermentation,[1] but it was not until 1878 that it was definitely proved that a disease of cattle called anthrax was due to a species of bacteria. what should be regarded as such proof had been formulated by henle in 1840. to prove that a certain sort of organism when found associated with a disease is the cause of the disease, three things are necessary: 1. the organism must always be found in the diseased animal and associated with the changes produced by the disease. 2. the organism so found must be grown outside of the body in what is termed pure cultures, that is, not associated with any other organisms, and for so long a time with constant transfers or new seedings that there can be no admixture of other products of the disease in the material in which it is grown. 3. the disease must be produced by inoculating a susceptible animal with a small portion of such a culture, and the organism shown in relation to the lesions so produced. it is worth while to devote some attention to the disease anthrax. this occupies a unique position, in that it was the first of the infectious diseases to be scientifically investigated. in this investigation one fact after another was discovered and confirmed; some of these facts seemed to give clearer conceptions of the disease, others served to make it more obscure; new questions arose with each extension of knowledge; in the course of the work new methods of investigation were discovered; the sides of the arch were slowly and painfully erected by the work of many men, and finally one man placed the keystone and anthrax was for a long time the best known of diseases. men whose reputation is now worldwide first became known by their work in this disease. it was a favorable disease for investigation, being a disease primarily of cattle, but occasionally appearing in man, and the susceptibility of laboratory animals made possible experimental study. anthrax is a disease of domestic cattle affecting particularly bovine cattle, horses and sheep, swine more rarely. the disease exists in practically all countries and has caused great economic losses. there are no characteristic symptoms of the disease; the affected cattle have high fever, refuse to eat, their pulse and respiration are rapid, they become progressively weaker, unable to walk and finally fall. the disease lasts a variable time; in the most acute cases animals may die in less than twenty-four hours, or the disease may last ten or fourteen days; recovery from the disease is rare and treatment has no effect. it does not appear in the form of epidemics, but single cases appear frequently or rarely, and there is seemingly no extension from case to case, animals in adjoining stalls to the sick are not more prone to infection than others of the herd. on examination after death the blood is dark and fluid, the spleen is greatly enlarged (one of the names of the disease "splenic fever" indicates the relation to the spleen) and there is often bloody fluid in the tissues. where the disease is prevalent there are numbers of human cases. only those become infected who come into close relations with cattle, the infection most commonly taking place from small wounds or scratches made in skinning dead cattle or in handling hides. the wool of sheep who die of the disease finds its way into commerce, and those employed in handling the wool have a form of anthrax known as wool-sorters' disease in which lesions are found in the lungs, the organisms being mingled with the wool dust and inspired. in boston occasional cases of anthrax appear in teamsters who are employed in handling and carrying hides. the disease in man is not so fatal as in cattle, for it remains local for a time at the site of infection, and this local disease can be successfully treated. the beginning of our knowledge of the cause dates from 1851, when small rod-shaped bodies (fig. 17) were found in the blood of the affected cattle, and by the work of a number of observers it was established that these bodies were constantly present. nothing was known of their nature; some held that they were living organisms, others that they were formed in the body as a result of the disease. next the causal relation of these bodies with the disease was shown and in several ways. the disease could be caused in other cattle by injecting blood containing the rods beneath the skin, certainly no proof, for the blood might have contained in addition to the rods something which was the real cause of the disease. next it was shown that the blood of the unborn calf of a cow who died of the disease did not contain the rods, and the disease could not be produced by inoculating with the calf's blood although the blood of the mother was infectious. this was a very strong indication that the rods were the cause; the maternal and foetal blood are separated by a membrane through which fluids and substances in solution pass; but insoluble substances, even when very minutely subdivided, do not pass the membrane. if the cause were a poison in solution, the foetal blood would have been as toxic as the maternal. the blood of infected cattle was filtered through filters made of unbaked porcelain and having very fine pores which allowed only the blood fluid to pass, holding back both the blood corpuscles and the rods, and such filtered blood was found to be innocuous. it was further shown that the rods increased enormously in number in the infected animal, for the blood contained them in great numbers when but a fraction of a drop was used for inoculation. attempts were also made with a greater or less degree of success to grow the rod shaped organisms or bacilli in various fluids, and the characteristic disease was produced by inoculating animals with these cultures; but it remained for koch, 1878, who was at that time an obscure young country physician, to show the life history of the organism and to clear up the obscurity of the disease. up to that time, although it had been shown that the rods or bacilli contained in the blood were living organisms and the cause of the disease, this did not explain the mode of infection; how the organisms contained in the blood passed to another animal, why the disease occurred on certain farms and the adjoining farms, particularly if they lay higher, were free. koch showed that in the cultures the organisms grew out into long interlacing threads, and that in these threads spores which were very difficult to destroy developed at intervals; that the organisms grew easily in bouillon, in milk, in blood, and even in an infusion of hay made by soaking this in water. this explained, what had been an enigma before, how the fields became sources of infection. the infection did not spread from animal to animal by contact, but infection took place from eating grass or hay which contained either the bacilli or their spores. when a dead animal was skinned on the field, the bacilli contained in the blood escaped and became mingled with the various fluids which flowed from the body and in which they grew and developed spores. it was shown by pasteur that even when a carcass was buried the earthworms brought spores developed in the body to the surface and deposited them in their casts, and in this way also the fields became infected. from such a spot of infected earth the spores could be washed by the rains over greater areas and would find opportunity to develop further and form new spores in puddles of water left on the fields, which became a culture medium by the soaking of the dead grass. the contamination of the fields was also brought about by spreading over them the accumulations of stable manure which contained the discharges of the sick cattle. the tendency of the disease to extend to lower-lying adjacent fields was due to the spores being washed from the upper fields to the lower by the spring freshets. meanwhile pasteur had discovered that by growing the organisms at higher temperatures than the animal body, it was possible to attenuate the virulence of the bacilli so that inoculations with these produced a mild form of the disease which rendered the inoculated animals immune to the fatal disease. the description of pasteur's work on the disease as given in the account of his life by his son-in-law is fascinating. hides and wool taken from dead animals invariably contained the spores which could pass unharmed through some of the curing processes, and were responsible for some of the cases in man. owing to the introduction of regulations which were based on the knowledge of the cause of the disease and the life history of the organism, together with the prophylactic inoculation devised by pasteur, the incidence of the disease has been very greatly lessened. looking at the matter from the lowest point of view, the money which has been saved by the control of the disease, as shown in its decline, has been many times the cost of all the work of the investigations which made the control possible. it is a greater satisfaction to know that many human lives have been saved, and that small farmers and shepherds have been the chief sharers in the economic benefits. the indirect benefits, however, which have resulted from the application of the knowledge of this disease, and the methods of investigation developed here, to the study of the infections more peculiar to man, are very much greater. footnote: [1] the interesting analogy between fermentation and infectious disease did not escape attention. a clear fluid containing in solution sugar and other constituents necessary for the life of the yeast cells will remain clear provided all living things within it have been destroyed and those in the air prevented from entering. if it be inoculated with a minute fragment of yeast culture containing a few yeast cells, for a time no change takes place; but gradually the fluid becomes cloudy, bubbles of gas appear in it and its taste changes. finally it again becomes clear, a sediment forms at the bottom, and on re-inoculating it with yeast culture no fermentation takes place. the analogy is obvious, the fluid in the first instance corresponds with an individual susceptible to the disease, the inoculated yeast to the contagion from a case of transmissible disease, the fermentation to the illness with fever, etc., which constitutes the disease, the returning clearness of the fluid to the recovery, and like the fermenting fluid the individual is not susceptible to a new attack of the disease. it will be observed that during the process both the yeast and the material which produced the disease have enormously increased. fermentation of immense quantities of fluid could be produced by the sediment of yeast cells at the bottom of the vessel and a single case of smallpox would be capable of infecting multitudes. chapter vi classification of the organisms which cause disease.--bacteria: size, shape, structure, capacity for growth, multiplication and spore formation.--the artificial cultivation of bacteria.--the importance of bacteria in nature.--variations in bacteria.--saprophytic and parasitic forms.--protozoa.--structure more complicated than that of bacteria.--distribution in nature.--growth and multiplication.-conjugation and sexual reproduction.--spore formation.--the necessity for a fluid environment.--the food of protozoa.--parasitism.--the ultra-microscopic or filterable--organisms.--the limitation of the microscope.--porcelain filters to separate organisms from a fluid.-foot and mouth disease produced by an ultra-microscopic organism.-other diseases so produced.--do new diseases appear? the living organisms which cause the infectious diseases are classified under bacteria, protozoa, yeasts, moulds, and ultra-microscopic organisms. it is necessary to place in a separate class the organisms whose existence is known, but which are not visible under the highest powers of the microscope, and have not been classified. the yeasts and moulds play a minor part in the production of disease and cannot be considered in the necessary limitation of space.

(_l_) the screw-shaped spirochite which is the cause of syphilis.] the bacteria (fig. 17) are unicellular organisms and vary greatly in size, shape and capacity of growth. the smallest of the pathogenic or disease-producing bacteria is the influenza bacillus, 1/51000 of an inch in length and 1/102000 of an inch in thickness; and among the largest is a bacillus causing an animal disease which is 1/2000 of an inch in length and 1/25000 of an inch in diameter. among the free-living non-pathogenic forms much larger examples are found. in shape bacteria are round, or rod-shaped, or spiral; the round forms are called micrococci, the rod-shaped bacilli and the spiral forms are called spirilli. a clearer idea of the size is possibly given by the calculation that a drop of water would contain one billion micrococci of the usual size. their structure in a general way conforms with that of other cells. on the outside is a cell membrane which encloses cytoplasm and nucleus; the latter, however, is not in a single mass, but the nuclear material is distributed through the cell. many of the bacteria have the power of motion, this being effected by small hair-like appendages or flagellæ which may be numerous, projecting from all parts of the organisms or from one or both ends, the movement being produced by rapid lashing of these hairs. a bacterium grows until it attains the size of the species, when it divides by simple cleavage at right angles to the long axis forming two individuals. in some of the spherical forms division takes place alternately in two planes, and not infrequently the single individuals adhere, forming figures of long threads or chains or double forms. the rate of growth varies with the species and with the environment, and under the best conditions may be very rapid. a generation, that is, the interval between divisions, has been seen to take place in twenty minutes. at this rate of growth from a single cholera bacillus sixteen quadrillion might arise in a single day. such a rate of growth is extremely improbable under either natural or artificial conditions, both from lack of food and from the accumulation in the fluid of waste products which check growth. many species of bacteria in addition to this simple mode of multiplication form spores which are in a way analogous to the seeds of higher plants and are much more resistant than the simple or vegetative forms; they endure boiling water and even higher degrees of dry heat for a considerable time before they are destroyed. when these spores are placed in conditions favorable for bacterial life, the bacterial cells grow out from them and the usual mode of multiplication continues. this capacity for spore formation is of great importance, and until it was discovered by cohn in 1876, many of the conditions of disease and putrefaction could not be explained. spores, as the seeds of plants, often seem to be produced when the conditions are unfavorable; the bacterium then changes into this form, which under natural conditions is almost indestructible and awaits better days. the bacteria are divided into species, the classification being based on their forms, on the mode of growth, the various substances which they produce and their capacity for producing disease. the differentiation of species in bacteria is based chiefly upon their properties, there being too little difference in form and size to distinguish species. the introduction of methods of culture was followed by an immediate advance of our knowledge concerning them. this method consists in the use of fluid and solid substances which contain the necessary salts and other ingredients for their food, and in or on which they are planted. the use of a solid or gelatinous medium for growth has greatly facilitated the separation of single species from a mixture of bacteria; a culture fluid containing sufficient gelatine to render it solid when cooled is sown with the bacteria to be tested by placing in it while warm and fluid, a small portion of material containing the bacteria, and after being thoroughly mixed the fluid is poured on a glass plate and allowed to cool. the bacteria are in this way separated, and each by its growth forms a single colony which can be further tested. it is self-evident that all culture material must be sterilized by heat before using, and in the manipulations care must be exercised to avoid contamination from the air. the refraction index of the bacterial cell is so slight that the microscopic study is facilitated or made possible by staining them with various aniline dyes. owing to differences in the cell material the different species of bacteria show differences in the facility with which they take the color and the tenacity with which they retain it, and this also forms a means of species differentiation. the interrelation of science is well shown in this, for it was the discovery of the aniline dyes in the latter half of the nineteenth century which made the fruitful study of bacteria possible. from the simplicity of structure it is not improbable that the bacteria are among the oldest forms of life, and all life has become adapted to their presence. they are of universal distribution; they play such an important part in the inter-relations of living things that it is probable life could not continue without them, at least not in the present way. they form important food for other unicellular organisms which are important links in the chain; they are the agents of decomposition, by which the complex substances of living things are reduced to elementary substances and made available for use; without them plant life would be impossible, for it is by their instrumentality that material in the soil is so changed as to be available as plant food; by their action many of the important foods of man, often those especially delectable, are produced; they are constantly with us on all the surfaces of the body; masses live on the intestinal surfaces and the excrement is largely composed of bacteria. it has been said that life would be impossible without bacteria, for the accumulation of the carcasses of all animals which have died would so encumber the earth as to prevent its use; but the folly of such speculation is shown by the fact that animals would not have been there without bacteria. it has been shown, however, that the presence of bacteria in the intestine of the higher animals is not essential for life. the coldest parts of the ocean are free from those forms which live in the intestines, and fish and birds inhabiting these regions have been found free from bacteria; it has also been found possible to remove small animals from their mother by cæsarian section and to rear them for a few weeks on sterilized food, showing that digestion and nutrition may go on without bacteria. certain species of bacteria are aërobic, that is, they need free oxygen for their growth; others are anaërobic and will not grow in the presence of oxygen. most of the bacteria which produce disease are facultative, that is, they grow either with or without oxygen; but certain of them, as the bacillus of tetanus, are anaërobic. there is, of course, abundance of oxygen in the blood and tissues, but it is so combined as to be unavailable for the bacteria. bacteria may further be divided into those which are saprophytic or which find favorable conditions for life outside of the body, and the parasitic. many are exclusively parasitic or saprophytic, and many are facultative, both conditions of living being possible. it has been found possible by varying in many ways the character of the culture medium and temperature to grow under artificial conditions outside of the body most, if not all, of the bacteria which cause disease. thus, such bacteria as tubercle bacilli and the influenza bacillus can be cultivated, but they certainly would not find natural conditions which would make saprophytic growth possible. bacteria may be very sensitive to the presence of certain substances in the fluid in which they are growing. growth may be inhibited by the smallest trace of some of the metallic salts, as corrosive sublimate, although the bacteria themselves are not destroyed. if small pieces of gold foil be placed on the surface of prepared jelly on which bacteria have been planted, no growth will take place in the vicinity of the gold foil. variations can easily be produced in bacteria, but they do not tend to become established. in certain of the bacterial species there are strains which represent slight variations from the type but which are not sufficient to constitute new species. if the environment in which bacteria are living be unusual and to a greater or less degree unfavorable, those individuals in the mass with the least power of adaptibility will perish, those more resistant and with greater adaptability will survive and propagate; and the peculiarity being transmitted a new strain will arise characterized by this adaptability. bacteria with slight adaptability to the environment of the tissues and fluids of the animal body can, by repeated inoculations, become so adapted to the new environment as to be in a high degree pathogenic. in such a process the organisms with the least power of adaptation are destroyed and new generations are formed from those of greater power of adaptation. when bacteria are caused to grow in a new environment they may acquire new characteristics. the anthrax bacilli find the optimum conditions for growth at the temperature of the animal body, but they will grow at temperatures both above and below this. pasteur found that by gradually increasing the temperature they could be grown at one hundred and ten degrees. when grown at this temperature they were no longer so virulent and produced in animals a mild non-fatal form of anthrax which protected the animal when inoculated with the virulent strain. the well known variations in the character of disease, shown in differences in severity and ease of transmission, seen in different years and in different epidemics, may be due to many conditions, but probably variation in the infecting organisms is the most important. the protozoa, like the bacteria, are unicellular organisms and contain a nucleus as do all cells. they vary in size from forms seen with difficulty under the highest power of the microscope to forms readily seen with the unaided eye. their structure in general is more complex than is the structure of bacteria, and many show extreme differentiation of parts of the single cells, as a firm exterior surface or cuticle, an internal skeleton, organs of locomotion, mouth and digestive organs and organs of excretion. they are more widely distributed than are the bacteria, and found from pole to pole in all oceans and in all fresh water. there are many modes of multiplication, and these are often extremely complicated. the most general mode and one which is common to all is by simple division; a modification of this is by budding in which projections or buds form on the body and after separation become new organisms. in other cases spores form within the cell which become free and develop further into complete organisms. these simple modes of multiplication often alternate in the same organism with sexual differentiation and conjugation. there is never a permanent sexual differentiation, but the sexual forms develop from a simple and non-sexual organism. usually the sexual forms develop only in a special environment; thus the protozoon which in man is the cause of malaria, multiplies in the human blood by simple division, but in the body of the mosquito multiplication by sexual differentiation takes place. under no conditions is multiplication so rapid as with the bacteria, and in general the simpler the form of organism the more rapid is the multiplication. it is common to all of the protozoa to develop forms which have great powers of resistance, this being due in some cases to encystment, in which condition a resistant membrane is formed on the outside, in others to the production of spores. a fluid environment is essential to the life of the protozoa, but the resistant forms can endure long periods of dryness or other unfavorable environmental conditions. the universal distribution of the protozoa is due to this; the spores or cysts can be carried long distances by the wind and develop into active forms when they reach an environment which is favorable. their distribution in water depends upon the amount of organic material this contains. in pure drinking water there may be very few, but in stagnant water they are very numerous, living not on the organic material in solution in this, but on the bacteria which find in such fluid favorable conditions for existence. the food of protozoa consists chiefly of other organisms, particularly bacteria, and they are classed with the animals. the protozoa are the most widely distributed and the most universal of the parasites. the infectious diseases which they produce in man, although among the most serious are less in number than those produced by bacteria. so marked is the tendency to parasitism that they are often parasitic for each other, smaller forms entering into and living upon the larger. variation does not seem to be so marked in the protozoa as in the bacteria, though this is possibly due to our greater ignorance of them as a class. we are not able, except in rare instances, to grow them in pure culture, and study innumerable generations under changes in the environment, as the bacteria have been studied. if we regard the living things on earth from the narrow point of view as to whether they are necessary or useless or hostile to man, the protozoa must be regarded as about the least useful members of the biological society. it is very possible that such a conclusion is due to ignorance; so closely are all living things united, so dependent is one form of cell activity upon other forms that it is impossible to foretell the result of the removal of a link. the protozoa do not seem to be as necessary for the life of man as are the bacteria; they produce many of the diseases of man, many of the diseases of animals on which man depends for food; they cause great destruction in plant life, and in the soil they feed upon the useful bacteria. it is well to remember, however, that fifty years ago several of the organs of the body whose activity we now recognize as furnishing substances necessary for life were regarded as useless members and, since they became the seat of tumors, as dangerous members of the body. the only organ which now seems to come into such a class is the vermiform appendix, and its lowly position among organs is due merely to an unhappy accident of development. the class of organisms known as the filterable viruses or the ultra-microscopic or the invisible organisms have a special interest in many ways. the limitation in the power of the microscope for the study of minute objects is due not to a defect in the instrument but to the length of the wave of light. it is impossible to see clearly under the microscope using white light, objects which are smaller in diameter than the length of the wave which gives a limit of 0.5µ. or 1/125,000 of an inch. by using waves of shorter length, as the ultra-violet light, objects of 0.1µ. or 1/250000 of an inch can be seen; but as these methods depend upon photography for the demonstration of the object the study is difficult. the presence of objects still smaller than 0.1 m. can be detected in a fluid by the use of the dark field illumination and the ultra-microscope, the principle of which is the direction of a powerful oblique ray of light into the field of the microscope. the objects are not visible as such, but the dispersion of the light by their presence is seen. the demonstration that infectious diseases were produced by organisms so small as to be beyond demonstration with the best microscopes was made possible by showing, that some fluid from a diseased animal was infectious; and capable of producing the disease when inoculated into a susceptible animal. the fluid was then filtered through porcelain filters which were known to hold back all objects of the size of the smallest bacteria and the disease produced by inoculating with the clear filtrate. there are a number of such filters of different degrees of porosity manufactured, and they are often used to procure pure water for drinking, for which use they are more or less, generally however, less efficacious. the filter has the form of a hollow cylinder and the liquid to be filtered is forced through it under pressure. for domestic use the filter is attached by its open end to the water tap and the pressure from the mains forces the water through it. in laboratory uses, denser filters of smaller diameters are used, and the filter is surrounded by the fluid to be tested. the open end of the filter passes into a vessel from which the air is exhausted and filtration takes place from without inward. the test of the effectiveness of the filter is made by adding to the filtering fluid some very minute and easily recognizable bacteria and testing the filtrate for their presence. these filters have been studied microscopically by grinding very thin sections and measuring the diameter of the spaces in the material. these are very numerous, and from 1/25000 to 1/1000 of an inch in diameter, spaces which would allow bacteria to pass through, but they are held back by the very fine openings between the spaces and by the tortuosity of the intercommunications. when the coarser of such filters have been long in domestic service in filtering drinking water, bacteria may grow in and through them giving greater bacterial content to the supposed bacteria-free filtrate than in the filtering water. that an animal disease was due to such a minute and filterable organism was first shown by loeffler in 1898 for the foot and mouth disease of cattle. this is one of the most infectious and easily communicable diseases. the lesions of the disease take the form of blisters which form on the lips and feet and in the mouths of cattle, and inoculation with minute quantities of the fluid in the blisters produces the disease. loeffler filtered the fluid through porcelain filters, hoping to obtain a material which inoculated into other cattle would render them immune, and to his surprise found that the typical disease was produced by inoculating with the filtrate. naturally the first idea was that the disease was caused by some soluble poison and not by a living organism, but this was disproved in a number of ways. the most powerful poison known is obtained from cultures of the tetanus bacillus of which 0.000,000,1 of a gram (one gram is 15.43 grains) kills a mouse, or one gram kills ten million mice. loeffler found that 1/30 gram of the contents of the vesicles killed a calf of two hundred kilograms weight, and assuming that the essential poison was present in the fluid in one part to five hundred it would be several hundred times more powerful than the tetanus poison. further, the disease produced by inoculation of the filtrate was itself inoculable and could be transmitted from animal to animal. it was also found that when the virus was filtered several times it ceased to be inoculable, showing that each time the fluid was passed through the filter some of the minute organisms contained in it were held back. it is not known whether these organisms belong to the bacteria or protozoa, and naturally nothing is known as to their form, size and structure. up to the present about twenty diseases are known to be due to a filterable virus, and among these are some of the most important for animals and for man. among the human diseases, yellow fever, poliomyelitis, and dengue are so produced; of the animal diseases in addition to foot and mouth disease, pleuropneumonia, cattle plague, african horse sickness, several diseases of fowls and the mosaic disease of the tobacco plant have all been shown to be due to a filterable virus. of these organisms the largest is that which produces pleuropneumonia in cattle, and this alone has been cultivated. it gives a slight opacity to the culture fluids, and when magnified two thousand diameters appears as a minute spiral or round or stellate organism having a variety of forms. its size is such that it passes the coarse, but is held back by the finer, filters and it is possible that this does not belong to the same class with the others.[1] the diseases produced by the filterable viruses taken as a class show much similarity. they run an acute course, are severe, and the immunity produced by the attack endures for a long time. considered in its biological relations, infection is the adaptation of an organism to the environment which the body of the host offers. it is rather singular that variations in organisms represented by such adaptation do not more frequently arise, in which case new diseases would frequently occur. it cannot be denied that new diseases appear, but there is no certain evidence that they do, and there is equally no evidence that diseases disappear. from the meagre descriptions of diseases, usually of the epidemic type, which have come down to us from the past, it is difficult to recognize many of the diseases described. the single diseases are recognized by comparing the causes, the lesions and the symptoms with those of other diseases, and new diseases are constantly being separated off from other diseases having more or less common features. many new diseases have been recognized and named, but it is always more than probable that previously they were confounded with other diseases. smallpox is such a characteristic disease that one would think it would have been recognized as an entity from the beginning, but although the description of some of the epidemics in remote times conform more or less to the disease as we know it, the first accurate description is in the eighth century by the arabian physician rhazes. cerebro-spinal meningitis was not recognized as a separate disease until 1803, diphtheria not until 1826, and the separation between typhoid and typhus fever was not made before 1840. nor is it sure that any diseases have disappeared, although there seems to have been a change in the character of many. it is difficult to reconcile leprosy as it appears now with the universal horror felt towards it, due to the persistence of the old traditions. it is possible, however, that the disease has not changed its character, but that such diseases as smallpox, syphilis, and certain forms of tuberculosis were formerly confounded with leprosy, thus giving a false idea of its prevalence. in certain cases the adaptation of the organism is for a narrow environment; for example, the parasitism may extend to a simple species only, in others the adaptation may extend to a number of genera. in certain cases the adaptation is mutual, extending to both parasite and host and resulting in symbiosis, and this condition may be advantageous for both. certain of the protozoa harbor within them cells of algæ utilizing to their own advantage the green chlorophil of the algæ in obtaining energy from sunlight and in turn giving sustenance to the algæ. although the algæ are useful guests, when they become too numerous the protozoan devours them. it is evident that symbiosis is the most favorable condition for the existence of the parasite, and an injurious action exerted by the parasite on the host unfavorable. the death of the host is an unfortunate incident from the parasite's point of view in that it is deprived of habitation and food supply, being placed in the same unfortunate situation as may befall a social parasite by the death of his host. footnote: [1] flexner has recently succeeded in isolating and cultivating the organism of poliomyelitis, but the organism is so small that its classification is not possible. chapter vii the nature of infection.--the invasion

injury of the body by living organisms which enter it. the body is in relation to the external world by its surfaces only, and organisms must enter it by some one of these surfaces. it is true that the bacteria in the intestine--either those normally present or unusual varieties--may, under certain circumstances, produce substances which are injurious when absorbed; but this is not infection, and is analogous to any other sort of poisoning. each surface of the body has its own bacterial flora. organisms live on the surface either on matter which is secreted by the surface or they use up an inappreciable amount of body material. many of these bacteria are harmless, some are protective, producing by their growth such changes in the surface fluids that these become hostile to the existence of other and pathogenic forms. the surfaces also frequently harbor pathogenic organisms which await some condition to arise which will permit them to effect entrance into the tissues. the surfaces of the body protect from invasion to a greater or less degree. the skin protects by the impervious horny layer on the outside, the external cells of which are dead and constantly being thrown off. bacteria are always found on and in this layer, but the conditions for growth here are not very favorable and the surface is constantly cleansed by desquamation. the new cells to supply the loss are produced in the deepest layer of the epidermis, and the movement of cells and fluids takes place from within outwards. the protection is less perfect about the hairs and the sweat glands. infection by the route of the sweat glands is, however, uncommon, for the sweat is a fluid unfavorable for bacterial growth and the flow acts mechanically in washing away organisms which may have entered the ducts. infection by the route of the hair follicles is common. there is no mechanical cleansing as by the sweat, the space around the hair is large and the accumulated secretion of the hair glands and the desquamated cells furnish a material in which bacteria may grow. growing as a mass in this situation, they may produce sufficient toxic material to destroy adjacent living cells and thus effect entrance. infection from the eye is not common, the surface, though moist, is smooth; the eyelashes around the margin of the lids give some mechanical protection from the entrance of bacteria contained in dust, and the movements of the lids and the constant and easily accelerated secretion of tears act mechanically in removing foreign substances. it is possible that the mechanical cleansing of the skin by the daily bath may have some action in preventing infection. the internal surfaces are much more exposed to attack and the protection is not so efficient. the moisture of these surfaces is both a protection and a source of danger. it protects by favoring the lodgment near the orifices of organisms which are in the inspired air, for when bacteria touch a moist surface they cannot be raised from this and carried further by air currents. the moisture is a source of danger in that it favors the growth of bacteria which lodge on the surface. the respiratory surface which is most exposed to infection from the air is further protected by the cilia, which are fine hair-like processes covering the cells of the surface and which by their constant motion sweep out fine particles of all sorts which lodge upon them. the cavity of the mouth harbors large numbers of organisms, many of them pathogenic. it forms a depot from which bacteria may pass to communicating surfaces and infection from these may result. food particles collect in the mouth and provide culture material, and there are many crypts and irregularities of surface which oppose mechanical cleaning. infection of the middle ear, the most common cause of deafness, takes place by means of the eustachian tube which connects the cavity of the ear with the mouth. organisms from the mouth can extend into the various large salivary glands by means of the ducts and give rise to infections. the tonsils, particularly in children, provide a favorable surface for infection. the mucous surface extends into these forming deep pockets lined with very thin epithelium, and in these débris of all sorts accumulates and provides material favorable for bacterial growth. the lungs at first sight seem to offer the most favorable surface for infection. the surface, ninety-seven square yards, is enormous; it is moist, the epithelial covering is so thin as to give practically no mechanical protection, large amounts of air constantly pass in and out, and the surface is in contact with this. they are protected from infection in many ways. the tubes or bronchi by which the air passes into and from the lungs are covered with cilia; the surface area of these tubes constantly enlarges as they branch, the sum of the diameters of the small tubes being many times greater than that of the windpipe, and this enlargement by retarding the motion of the air favors the lodgment of particles on the surface whence they are removed by the action of the cilia. the entering air is also brought closely in contact with a moist surface at the narrow opening of the larynx. that bacteria and other foreign substances can enter the lungs in spite of these guards is shown not only by the infections which take place here, but also by the large amount of black carbon deposited in them from the soot contained in the air. infection rarely takes place from the surface of the gullet or oesophagus which leads from the mouth to the stomach. this is due to the smoothness of the surface and to the rapidity with which food passes over it. infection by the stomach also is rare, for this contains a strong acid secretion which destroys many of the bacteria which are taken in with the food. it is found impossible to infect animals with cholera unless the acidity of the stomach contents be neutralized by an alkali. many organisms, although their growth in the stomach is inhibited, are not destroyed there and pass into the intestines, where the conditions for infection are more favorable. this large and very irregular surface is bathed in fluid which is a good culture medium and but a single layer of cells covers it. the organisms which cause many of the infectious diseases in both man and animals find entrance by means of the alimentary canal, as cholera, dysentery, typhoid fever, chicken cholera, hog cholera. infection by the genito-urinary surface is comparatively rare. the surface openings are usually closed, and the discharge of urine has a mechanical cleansing effect. the wide tube of the vagina is further protected by a normal bacterial flora which produces conditions hostile to other and pathogenic bacteria. the most common infections are the sexual diseases, which are due to organisms which find favorable conditions for growth in and on the surface and which are conveyed from a similar surface by sexual contact. it remains a question whether bacteria can penetrate an intact surface producing no injury at the point of entrance and be carried by the lymph or blood into internal organs where they produce disease. internal infections are often found with seemingly intact body surfaces, but it is impossible to exclude the presence of minute or microscopic surface injuries by which the organisms may have entered. it is also possible that a slight injury at the point of entrance may heal so completely as to leave no trace. the chief danger from wounds is that their surfaces may become infected. death from wounds is due more frequently to infection than to the actual injury represented by the wounds. much depends upon the character of the wound. infection of clean wounds which are made by a sharp cutting instrument and from which there is abundant hæmorrhage with sealing of the edges of the wound by clotted blood, rarely happens. typical wounds of this sort are often made in shaving, and infection of such wounds is extraordinarily rare. if, with the wound, pathogenic organisms are placed in the tissue, or foreign substances such as bits of clothing are carried in with a bullet, for example, or if the instrument causing the wound be of such a character as to produce extensive lacerations of tissue, infection is more apt to occur. the less frequency of infection in modern wars is in part due to the simpler character of the wounds and in part to the fact that modern fixed ammunition is practically free from germs. the old spear-head, the arrow, the cross bow bolt, had little regard for the probabilities of infection. whether infection follows a wound depends both upon the entry of pathogenic organisms and upon these finding in the tissues suitable opportunities for growth. in wounds in which there is much laceration of tissue organisms find the most favorable conditions for development. the very slight wounds produced by the exploded cap in the toy pistol give suitable conditions for the development of the bacillus which produces tetanus or lockjaw. the deaths of children from lockjaw following a fourth of july celebration have often exceeded the total deaths in a central american revolution. the tetanus bacillus is a widely distributed organism, whose normal habitat is in the soil and which is usually present on the dirty hands of little boys. the toy-pistol wounds are made by small bits of paper or metal being driven into the skin by the explosion of the cap. the wound is of little moment, the surface becomes closed, and a bit of foreign substance, a few dead cells and the tetanus bacilli from the surface remain enclosed and in a few days the fatal disease develops. infection of the surfaces of old wounds such as the surface of an ulcer takes place with difficulty. large numbers of leucocytes which give protection by phagocytosis are constantly passing to the surface, and there is also a constant stream of fluid towards the surface. on such a surface there may be an abundant growth of pathogenic organisms, but no infection results. in most infections there is a focus where the infectious organisms are localized; this may correspond to the point of entrance on a surface or it may be in the interior of the body, the organisms being deposited there after entrance. at this primary localization, the _atrium_ of infection,[1] the organisms multiply and from this point further invasion takes place. many secondary foci may be formed in the organs by distribution of the organisms, or there may be infection of the blood and fluids of the body. the injuries which are produced depend upon the nature of the infecting organisms. the most common lesion consists in the death of the tissue about the infecting organisms. in most cases the sum of the changes are so characteristic that from them the nature of the infection is easily determined, and these changes often give names to the disease; thus tuberculosis is a disease characterized by the formation of tubercles or little nodules in the body. the situation of the foci of disease is determined by many conditions, the most important being the varying resistance of the different organs of the body to the growth of bacteria. certain organs, such as the central nervous system, the muscles, the testicles and the ovaries, have a high resistance to the growth of bacteria. the disease may be localized in certain organs because only in these do the bacteria find favorable conditions for growth. in spite of a high general resistance to infection the lesions in chronic glanders are most marked in the muscles, those of poliomyelitis in the spinal cord. there are few bacterial diseases which are localized in the blood, but many of the diseases caused by protozoa have this localization. in every infection some organisms enter the blood, which acts as a carrier and deposits them in the organs. bacteria cause disease by producing substances called toxines which are poisonous to the cells, and of which two sorts are distinguished. one form of toxines is produced by the bacteria as a sort of secretion, and is formed both in the body and when the bacteria are growing in cultures. substances of this character, many of them highly poisonous, are produced both by animals and plants. they may serve the purpose both of offence and defence, as in the case of the snake venom, and in other cases they seem to benefit their producers in no way whatever, and may even be injurious to them. after the different cereals have been grown for succeeding years in the same place, growth finally diminishes not from the exhaustion of the soil, but from the accumulation in it of substances produced by the plants. beneath certain trees, as the norway maple, grass will not grow, and it has been shown that the tree produces substances which inhibit the growth of grass. when bacteria are grown in a culture flask, growth ceases long before the nutritive material has been consumed, from the accumulation of waste products in the fluid. the other class of toxic substances, called endotoxines, are not secretion products, but are contained in the bacterial substance and become active by the destruction and disintegration of the bacteria. they can be artificially produced by grinding up masses of bacteria, and in the body the destruction and solution of bacteria which is constantly taking place sets them free. the toxines and the endotoxines are of an albuminous nature, and act only when they come in contact with the living cells within the body. when taken into the alimentary canal they are either not absorbed or so changed by the digestive fluids as to be innocuous. many of the ordinary food substances, even a material apparently so simple as the white of an egg, are highly injurious if they reach the tissues in an unchanged form. by means of these substances the bacteria produce such changes in their environment within the body that this becomes adapted to their parasitic existence. in symbiosis the bacteria probably undergo changes by which they become adapted to the environment, and in parasitism the environment becomes adapted to them. in the same way man can change his immediate environment by means of clothing, artificial heating, etc., and adapt it to his needs; or by hardening his body he can adapt it to the environment. the pathogenic bacterium finds the living tissue hostile, its cells devour him, the tissue fluids destroy him, and by means of the toxines he changes the environment from that of living to dead tissue, or in other ways so alters it that it is no longer hostile. the parasite has also means of passive defence comparable to the armor of the warrior in the past. it may form a protective mantle called a capsule around itself, which serves to protect it from the action of the body fluids. such capsule formation is a very common thing in the pathogenic organisms, and they are found only when these are growing in the body and do not appear in cultures (fig. 17-c). it is evident that just as the parasite has his weapons of offence and defence so has the host, otherwise there would be no recovery from infectious diseases. although many of the infectious diseases have a high mortality, which in rare instances reaches one hundred per cent, the majority do recover. in certain cases the recovery is attended by immunity, the individual being protected to a greater or less degree from a recurrence of the same disease. the immunity is never absolute; it may last for a number of years only, and usually, if the disease be again acquired, the second attack is milder than the primary. probably the most enduring immunity is in smallpox, although cases are known of two and even three attacks; the immunity is high in scarlet fever, measles, mumps and typhoid fever. the immunity from diphtheria is short, and in pneumonia, although there must be a temporary immunity, future susceptibility to the disease is probably increased. in certain cases the immunity is only local; the focus of disease heals because the tissue there has evolved means of protection from the parasite, but if any other part of the body be infected, the disease pursues the usual course. a boil, for example, is frequently followed by the appearance of similar boils in the vicinity due to the infection of the skin by the micrococci from the first boil, which by dressings, etc., have become spread over the surface. the natural methods of defence of the host against the parasites have formed the main subject in the study of the infectious diseases for the last twenty years. speculation in this territory has been rife and most of it fruitless, but by patient study of disease in man and by animal experimentation there has been gradually evolved a sum of knowledge which has been applied in many cases to the treatment of infectious diseases with immense benefit. research was naturally turned to this subject, for it was evident that the processes by which the protection of the body was brought about must be known before there could be a really rational method of treatment directed towards the artificial induction of such processes, or hastening and strengthening those which were taking place. previous to knowledge of the bacteria, their mode of life, their methods of infection and knowledge of the defences of the body, most of the methods of prevention and treatment of the infectious diseases was based largely on conjecture, the one brilliant exception being the discovery of vaccination by jenner in 1798. the host possesses the passive defences of the surfaces which have already been considered. the first theories advanced in explanation of immunity were influenced by what was known of fermentation. one, the exhaustion theory, assumed that in the course of disease substances contained in the body and necessary for the growth of the bacteria became exhausted and the bacteria died in consequence. another, the theory of addition, assumed that in the course of the disease substances inimical to the bacteria were formed. both these theories were inadequate and not in accord with what was known of the physiology of the body. the most general mode of defence is by phagocytosis, the property which many cells have of devouring and digesting solid substances (fig. 16-p). although this had been known to take place in the amoebæ and other unicellular organisms, the wide extent of the process and its importance in immunity was first recognized by metschnikoff in 1884 and the phagocytic theory of immunity advanced and defended by a brilliant series of experiments by metschnikoff and his pupils conducted in the pasteur institute. metschnikoff's first observations were made on the daphnea, a small animalcule just visible to the naked eye which lives in fresh water. the structure of the organism is simple, consisting of an external and internal surface between which there is a space, the body cavity; daphneæ are transparent and can be studied under the microscope while living. metschnikoff observed that certain of them in the aquarium gradually lost their transparency and died, and examining these he found they were attacked by a species of fungus having long, thin spores. these spores were taken into the intestine with other food; they penetrated the thin wall of the intestine, passed into the body cavity, multiplied there, and in consequence the animal died. in many cases, however, those penetrating became enclosed in cells which the body cavity contains and which correspond with the leucocytes of the blood; in these the spores were digested and destroyed. the daphneæ in which this took place recovered from the infection. here was a case in which all the stages of an infectious disease could be directly followed under the microscope, and the whole process was simple in comparison with infections in the higher animals. the pathogenic organism was known, the manner and site of invasion was clear, it was also evident that if the multiplication of the parasite was unchecked the animal died, but if the parasite was opposed by the body cells and destroyed the animal recovered. the studies were carried further into the diseases of the higher animals, and it was found the leucocytes in these played the same part as did the cells in the body cavity of the daphnea. the introduction of bacteria into certain animals was followed by their destruction within cells and no disease resulted; if this did not take place, the bacteria multiplied and produced disease. support also was given the theory by the demonstration at about the same time that in most of the infectious diseases the leucocytes of the blood became increased in number,--that in pneumonia, for instance, instead of the usual number of eight thousand in a cubic millimeter of blood, there were often thirty thousand or even fifty thousand. at about the same time also chemotaxis, or the action of chemical substances in attracting or repelling organisms, excited attention, and all these facts together became woven into the theory. it was soon seen, however, that this theory, based as it was on observation and supported by the facts observed, was not, at least in its first crude form, capable of general application. many animals have natural immunity to certain diseases; they do not have the disease under natural conditions, nor do they acquire the disease when the organisms causing it are artificially introduced into their tissues by inoculation. such natural immunity seemed to be unconnected with defence by phagocytosis, for the leucocytes of the animal might or might not have phagocytic reaction to the particular organisms to which the animal was immune. it was also seen that recovery from infection in certain diseases was unconnected with phagocytosis. it had also been demonstrated, by german observers chiefly, that the serum of the blood, the colorless fluid in which the corpuscles float, was itself destructive, and that in an animal rendered immune to a special bacterium the destructive action of the serum on that organism was greatly increased. in this hostile serum the bacteria often became clumped together in masses, the bodies became swollen, broken up, and finally disintegrated. this property of the serum was described as due to a substance in the serum called _alexine_, which in the immune animal became greatly increased in amount. it was even denied by some that phagocytosis of living bacteria took place, and that all those included in the cells were dead, having been destroyed in the first instance by the serum. the strife became a national one between the french and germans,--on the one side in france the phagocytic theory was defended, and in germany, on the other, the theory of serum immunity. the mass of experimental work which poured from the laboratories of the two countries in attack and defence became so great that it could not easily be followed. it had a good influence because, without the stimulation of this national rivalry, the knowledge which gradually arose from this work would not have been so quickly acquired. it is interesting that the mode of action of the serum in destroying bacteria was demonstrated not by a german but by bordet, a french observer and a pupil of metschnikoff. he showed that the serum contained two distinct substances, each necessary for the destructive action. the separate action of these substances can be studied since one is _thermolabile_, or destroyed by heating the serum to one hundred and thirty-three degrees; the other _thermostabile_, or capable of withstanding a greater degree of heat. these substances are known only by their effect, they have never been separated from the serum. the thermostabile substance, or _amboceptor_, as it is generally called, has in itself no destructive action on the bacteria; but in some way so alters them that they can be acted on by the thermolabile substance called _complement_ whose action is destructive. the amount of amboceptor may increase in the course of infection and its formation stimulated, the amount of complement remains unchanged. the action of the amboceptor is specific, that is, directed against a single species of bacterium only; the destructive power of the blood may be very great against a single bacterium species and have no effect on others. there seem naturally to be many different amboceptors in the blood, and the number may be very greatly increased. it has been shown as a result of the work of many investigators that the shield has two faces,--there is destruction both by cells and fluids and there is interaction by both. the amboceptors so necessary for the destructive action of the serum are produced by the body cells, particularly the leucocytes. the serum assists in pagocytosis by the action on bacteria of substances called _opsonins_ which are contained in it, and the formation of which can be very greatly stimulated. again, not all inclusion of bacteria within leucocytes is indicative of phagocytosis; in many cases the bacteria seem to find the best conditions for existence within the leucocytes, and these and not the bacteria are destroyed. so far it has been shown that the best defence of the body is, as is the best defence in war, by offensive measures, as illustrated by phagocytosis and destruction by the serum. both of these actions can be increased by their exercise just as the strength of muscular contraction can be increased by exercise, and the facility for doing everything increased by habit. certain of the infectious diseases are, as has been said, essentially toxic in their nature, and in cultures the organisms produce poisonous substances. by the injection into the tissues of such substances the same disturbances are produced as when the bacteria are injected. such a disease is diphtheria. in this there is only a superficial invasion of the tissues. the diphtheria bacilli are located on the surface of the tonsils or pharynx or windpipe, where, as a result of their action, the membrane so characteristic of the disease is produced. the membrane may be the cause of death when it is so extensively formed as to occlude the air passages, but the prominent symptoms of the disease, the fever, the weakness of the heart and the great prostration are due not to the presence of the membrane, but to the action of toxic substances which are formed by the bacteria growing in the superficial lesions and absorbed. tetanus, or lockjaw, is another example of these essentially toxic diseases. the body must find some means of counteracting or destroying these injurious toxic substances. it does this by forming antagonistic substances called antitoxines, which act not by destroying the toxines, but by uniting with them, the compound substance being harmless. it has been found that the production of antitoxine can be so stimulated by the injection of toxine that the blood of the animal used for the purpose contains large amounts of antitoxine. the horse is used in this way to manufacture antitoxine, and the serum injected into a patient with diphtheria has a curative action, a greater amount being thus introduced than the patient can manufacture. [illustration: fig. 18.--diagram to illustrate ehrlich's theory of antitoxine formation. the surface of the cell (_n_) is covered with receptors some of which (_b_) fit the toxine molecule, (_a_) allowing the toxine to act upon the cell. under the stimulus of this the cell produces these receptors in excess which enter into the blood and there combine with the toxine as in _a^1 b^1_, thus anchoring it and preventing it from acting upon the cells. the receptors _c_ and _d_ do not fit the toxine molecule.] a very ingenious theory which well accords with the facts has been given by ehrlich in explanation of the production of antitoxine and of the reaction between toxine and antitoxine (fig. 18). this is based on the hypothesis, which is in accord with all facts and generally accepted, that the molecules which enter into the structure of any chemical substance have in each particular substance a definite arrangement, and that in a compound substance each elementary substance entering into the compound molecule has chemical affinities, most of which may be satisfied by finding a suitable mate. ehrlich assumes that the very complex chemical substances which form the living cells have many unsatisfied chemical affinities, and that it is due to this that molecules of substances adapted for food can enter the cells and unite with them; but there must be some coincidence of molecular structure to enable the union to take place, the comparison being made of the fitting of a key into a lock. the toxines--that produced by the diphtheria bacillus being the best example--are substances whose molecular structure enables them to combine with the cells of the body, the combination being effected through certain chemical affinities belonging to the cells termed _receptors_. unless the living cells have receptors which will enable the combination with the toxine to take place, no effect can be produced by the toxine and the cells are not injured. this is the case in an animal naturally immune to the action of the diphtheria bacillus or its toxines. in the case of the susceptible animal the receptors of the cells of the different organs combine with the toxine to a greater or less extent, which explains the fact that different degrees of injury are produced in the different tissues; the toxine of tetanus, or lockjaw, for example, combines by preference with the nervous tissue, that of diphtheria with the lymphatic tissue. it is known that in accordance with the general law of injury and repair, a loss in any part of the body stimulates the tissue of the same kind to new growth and the loss is thus repaired; it is assumed that the cell receptors which combine with the toxine are lost for the cell which then produces them in excess. the receptors so produced pass into the blood, where they combine with the toxine which has been absorbed; the combination is a stable one, and the toxine is thus prevented from combining with the tissue cells. the antitoxine which is formed during the disease, and the production of which in the horse can be enormously stimulated by the injection of toxine, represents merely the excess of cell receptors, and when the serum of the horse containing them is injected in a case of diphtheria the same combination takes place as in the case of receptors provided by the patient. in the case of the destruction of bacteria in the blood by the action of amboceptor and complement, the amboceptor must be able to combine with both the bacterial cell and the complement which brings about its destruction, and just as antitoxine is formed so new amboceptors may be formed. few hypotheses have been advanced in science which are more ingenious, in better accord with the facts, have had greater importance in enabling the student to grasp the intricacies of an obscure problem, and which have had an equal influence in stimulating research. the immunity which results from disease in accordance with this theory, is due not to conditions preventing the entrance of organisms into the body, but to greater aptitude on the part of the cells to produce these protective substances having once learned to do so. an individual need not practise for many years, having once learned them, those combinations of muscular action used in swimming; but the habit at once returns when he falls into the water. infectious diseases and recovery are phases of the struggle for existence between parasite and host, and illustrate the power of adaptation to environment which is so striking a characteristic of living matter. footnotes: [1] the comparison here is with the atrium of a pompeiian house. chapter viii secondary, terminal and mixed infections.--the extension of infection in the individual.--tuberculosis.--the tubercle bacillus.--frequency of the disease.--the primary foci.--the extension of bacilli.--the discharge of bacilli from the body.--influence of the seat of disease on the discharge of bacilli.--the intestinal diseases.--modes of infection.--infection by sputum spray.--infection of water supplies.--extension of infection by insects.--trypanosome diseases.--sleeping sickness.--malaria.--the part played by mosquitoes.--parasitism in the mosquito.--infection as influenced by habits and customs.--hookworm disease.--inter-relation between human and animal diseases.--plague.--part played by rats in transmission.--the present epidemic of plague. the infectious diseases are often complicated by secondary infections, some other organism finding opportunity for invasion in the presence of the injuries produced in the primary disease. in many diseases, such as diphtheria, scarlet fever and smallpox, death is frequently due to the secondary infection. the secondary invaders not only find local conditions favoring a successful attack, but the activity of the tissue cells on which the production of protective substances essentially depends has suffered by the primary infection, or the cells are occupied in meeting the exigencies of this. the body is in the position of a state invaded by a second power where all its forces and resources are engaged in repelling the first attack. what are known as terminal infections occur shortly before death. no matter what the disease which causes death, in the last hours of life the body usually becomes invaded by organisms which find their opportunity in the then defenceless tissues, and the end is often hastened by this invasion. there are also mixed infections in which two different organisms unite in attack, each in some way assisting in the action of the other. the best known example of this is in the highly infectious disease of swine known as hog cholera. it has been shown that in this disease two organisms are associated,--one an invisible and filterable organism, and the other a bacillus. it was first supposed that the bacillus was the specific organism; it was found in the lesions and certain, but not all, the features of the disease were produced by inoculating hogs with pure cultures. the disease so produced is not contagious, and the contagious element seems to be due to the filterable virus. the modes of transmission of infectious diseases are of great importance and are the foundation of measures of public health. in the preceding chapter we have seen that in the infected individual the disease extends from one part of the body to another. there is a primary focus of disease from which the extension takes place, and the study of the modes of extension in the individual throws some light on the much more difficult subject of the transmission of disease from one individual to another. there are four ways by which extension in the individual may take place. 1. by continuity of tissue, an adjoining tissue or organ becoming infected by the extension of a focus of infection. 2. by means of lymphatics. organisms easily enter these vessels which are in continuity with the tissue spaces and receive the exudate from the focus of infection. the organisms are carried to the lymph nodes, which, acting as filters, retain them and for a time prevent a further extension. the following illustrates the importance of the part the nodes may play in mechanically holding back a flood of infection. a physician examined after death the body of a person who died from infection with a very virulent micrococcus and in the course of the examination slightly scratched a finger. one of the organs of the body was removed, sent to a laboratory and received by a laboratory worker, a woman physician, who had slight abrasions and fissures in the skin of the hands from contact with irritating chemicals. in the course of a few hours the wound on the finger of the man became inflamed, intensely painful, and red lines extended up the arm in the course of the lymphatic vessels, showing that the organisms were in the lymphatics and causing inflammation in their course. the lymph nodes in the armpit into which these vessels empty became greatly inflamed, swollen, and an abscess formed in them which was opened. there was high fever, great prostration, a serious illness from which the man did not recover for several months. the woman only handled the organ which was sent to the laboratory in order to place it in a fluid for preservation. she also had a focus of infection of a finger with the same red lines on the arm, showing extension by the lymphatics; but there was no halt of the infection in the armpit, for all the lymph nodes there had been removed several years before in the course of an operation for a tumor of the breast. a general infection of the blood took place, there was very high fever, and death followed in a few days. the halt of the infection is important in allowing time for the body to make ready its means of defence. one cannot avoid comparing the lymph node with a strong fortress thrown in the path of a victorious invading army behind which the defenders may gather and which affords them time to renovate their strength. 3. by means of the blood. the blood vessels are universally distributed, the smaller vessels have thin walls easily ruptured and easily penetrated. it is probable that in every infection some organisms enter the blood which, under usual conditions, is peculiarly hostile to bacteria. these may, however, be carried by the blood to other organs and start foci of infection in these. 4. by means of continuous surfaces. the bacteria may either grow along such surfaces forming a continuous or more or less broken layer, or may be carried from place to place in the fluids which bathe them. all these modes of extension are well shown in tuberculosis. this disease is caused by a small bacillus which does not produce spores, has no power of saphrophytic growth under natural conditions, and is easily destroyed. moisture and darkness are favorable conditions for its existence, sunlight and dryness the reverse. there are three varieties or strains of the tubercle bacilli which infect respectively man, cattle and birds, and each class of animals shows considerable resistance to the varieties of the bacillus which are most infectious for the others. the primary seat of the infection in man is generally in the upper part of the lung. the organisms settle on the surface here and cause multiplication of the cells and an inflammatory exudate in a small area. with the continuous growth of the bacilli in the focus, adjoining areas of the lung become affected, and there is further extension in the immediate vicinity by means of the lymphatics. small nodules are formed and larger areas by their coalescence. infection with tuberculosis is so common that at least three-fourths of all individuals over forty show evidences of it. the examination of two hundred and twenty-five children of the average age of five years who had died of diphtheria showed tuberculous infection in one-fifth of the cases and the frequency of infection increases with age. the defence on the part of the body is chiefly by the formation of dense masses of cicatricial tissue which walls off the affected area and in which the bacilli do not find favorable conditions for growth. this mode of defence, which is probably combined with the production of substances antagonistic to the toxines produced by the bacilli, is so efficacious that in the great majority of cases no further extension of the process takes place. in certain cases, however, the growth of the bacilli in the focus is unchecked, the tissue about them is killed and becomes converted into a soft semi-fluid material; further extension then takes place. all parts of the enormous surface of the lungs are connected by means of the system of air tubes or bronchi, and the bacilli have favorable opportunity for distribution, which is facilitated by sudden movements of the air currents in the lung produced by coughing. the defence of the body can still keep pace with the attack, and even in an advanced stage the infection can be checked in some cases permanently; in others the check is but temporary, the process of softening continues, and large cavities are produced by the destruction of the tissue. on the inner surface of these cavities there may be a rapid growth of bacilli. from the lungs the bacilli are carried by the lymphatics to the lymph nodes at the root of the lungs, in which a similar process takes place; this, on the whole, is favorable, because further extension by this route is for a time blocked. the extension by means of surfaces continues, the abundant sputum which is formed in the lungs and which contains large numbers of bacilli, becomes the vehicle of transportation. the windpipe and larynx may become infected, the back parts of each are more closely in contact with the sputum and are the parts most generally infected. a large part of the sputum is swallowed and infection of the intestine takes place, the lesions taking the form of large ulcers. from the intestinal ulcers there is further extension by means of the lymphatics, to the large lymph nodes in the back of the abdominal cavity (fig. 8-25); the bacilli may also pass from the ulcers into the abdominal cavity and be distributed over the surface of the peritoneum resulting in tuberculous peritonitis. when the disease has reached an advanced stage, bacilli in small numbers continually pass into the blood and are distributed by this over the body, producing small nodules in many places. in rare cases distribution by the blood is the principal method of extension, and immense numbers of small foci of disease are produced, the form of disease being known as acute miliary tuberculosis. although the bacilli are distributed everywhere, certain organs, as the brain and muscles, are usually exempt, because in these the conditions are not favorable to further growth of the bacilli. tuberculosis, although frequently a very acute disease, is usually one of the best types of a chronic disease and may last for many years. the chronic form is characterized by periods of slow or rapid advance when conditions arise in the body favorable for the growth of the bacilli, and periods when the disease is checked and quiescent, the defensive forces of the body having gained the upper hand. often the intervention of some other disease so weakens the defences of the body that the bacilli again find their opportunity. thus typhoid fever, scarlet fever and other diseases may be followed by a rapidly fatal advance of the tuberculosis, starting from some old and quiescent focus of the disease. tuberculosis is also one of the best examples of what is known as latent infection. in this the infectious organisms enter the body and produce primary lesions in which the organisms persist but do not extend owing to their being enclosed in a dense and resistant tissue, or to the production of a local immunity to their action. dr. head has recently examined the children of households in which there was open tuberculosis in some member of the household. by open tuberculosis is understood a case from which bacilli are being discharged. he found with scarcely an exception that all the children in such families showed evidences of infection. the detection of slight degrees of tuberculous infection is now made easy by certain skin reactions on inoculation of the skin with a substance derived from the tubercle bacilli. such latent infections may never become active and in the majority of cases do not. when, however, in consequence of some intercurrent disease or conditions of malnutrition the general defences of the body become weakened extension follows. such latent infections explain the enormous frequency of tuberculosis in prisons. under the general prison conditions infection in the prisons probably does not take place to any extent, and the disease is as common when the prisoners are kept in individual cells as in common prisons. it is probable that in these cases the prisoners have latent tuberculosis when entering, and the disease becomes active under the moral and physical depression which prison life entails. for the extension of infection from one individual to another the infecting organisms must in some way be transferred. the most important of the conditions influencing this are the localization of the disease and the character of the infectious organisms, particularly with regard to their resistance to the conditions met with outside of the body. the seat of disease influences the discharge of organisms; thus, if the disease involve any of the surfaces the organisms become mingled with the secretions of the surface and are discharged with these. if the seat of disease be in the lungs, the throat or the mouth, the sputum forms the medium of extension, which can take place in many ways. the sputum may become dried, forms part of the dust and the organisms enter with the inspired air. the organisms which cause most of the diseases in which the sputum becomes infectious are quickly destroyed by conditions in the open, such as the sunlight and drying; street dust does not play so prominent a part in extension as is generally supposed. organisms find much more favorable conditions within houses. it is now generally recognized that infection with tuberculosis does not take place in the open, but in houses in which the bacilli on being discharged are not destroyed. the hands, the clothing and surroundings even with the exercise of the greatest care may become soiled with the saliva. it has been shown that in coughing and speaking very fine particles of spray are formed by the intermingling of air and saliva, which may be projected a considerable distance and remain floating in the air for some time. these particles are so fine as to be invisible; they may be inspired, and their presence in the air forms an area of indeterminate extent around the infected person within which such infection is possible. such spray formation is also an important means of the extension of infection in the sick individual, for it is continually formed and inspired. it is in this way that the extreme prevalence of broncho-pneumonia in infants and young children is to be explained. no matter what the essential disease, an almost constant finding in young children after death is small areas of inflammation in the lungs in and around the terminations of the air tubes. the situation renders it evident that the organisms which caused the lesions entered the lung by the air tubes. the mouth of the child is unclean and harbors numbers of the same sort of organisms as those causing the lung inflammation; but in the absence of such a mode of infection as is given by spray formation it is difficult to see how the extension from the mouth to the lungs could take place. the weakened condition of the body in these cases favors the secondary infection. if the disease be located in the intestines, as in typhoid fever and dysentery, the organisms are contained in the fecal discharges, and by means of these the infection is extended. in typhoid fever, dysentery and cholera massive infections of the populace may take place from the contamination of a water supply and the disease be extended over an entire city. one of the most striking instances of this mode of extension was in the epidemic of cholera in hamburg in 1892. there were two sources of water supply, one of which was infected, and the cases were distributed in the city in the track of the infected supply. many such instances have been seen in typhoid fever. certain articles of food, particularly milk, serve as sources of infection. this is more apt to happen when the organism causing the infection grows easily outside of the body. a few such organisms entering into the milk can multiply enormously in a few hours and increase the amount of infectious material. in all these cases the sick individual remains a source of infection, for it is almost impossible to avoid some contamination of the body and the immediate surroundings with the organisms contained in the discharges. transmission by air plays but little part in the extension of infection. in such a disease as smallpox, where the localization is on the surface of the body, the organisms are contained in or on the thin epithelial scales which are constantly given off. these are light, and may remain floating in the air and carried by air currents just as is the pollen of plants. there seem to have been cases of smallpox where other modes of more direct transmission could be excluded and in which the organisms were carried in the air over a considerable space. all sorts of intermediate objects, both living and inanimate, such as persons, domestic animals, toys, books, money, etc., can serve as conveyors of infection. insects play a most important part in the transmission of disease, and in certain cases, as when a disease is localized in the blood, this is the only means of transmission. there are three ways in which the insect plays the rôle of conveyor. 1. the insect may play a purely passive part in that its exterior surface becomes contaminated with the discharges of the sick person, and in this way the organisms of disease may be conveyed to articles of food, etc. the ordinary house fly conveys in this way the organisms of typhoid and dysentery. flies seek the discharges not only for food, but for the purpose of depositing their eggs, and the hairy and irregular surface of their feet facilitates contamination and conveyance. when flies eat such discharges the organisms may pass through the alimentary canal unchanged and be deposited with their feces; they also often vomit or regurgitate food, and in this way also contaminate objects. flies very greedily devour the sputum of tuberculous patients, and the tubercle bacilli contained in this pass through them unchanged and are deposited in their feces. [illustration: fig. 19.--trypanosomes from birds. all the trypanosomes are very much alike. they contain a nucleus represented by the dark area in the centre and a fur-like membrane terminating in a long whip-like flagellum. they have the power of very active motion within the blood.] 2. diseases which are localized in the blood are transmitted by biting flies. the biting apparatus becomes contaminated with the organisms contained in the blood, and these are directly inoculated into the blood of the next victim. the trypanosome diseases form the best example of this mode of transmission. the trypanosomes are widely distributed, exclusively parasitic, flagellated protozoa which live in the blood of a large number of animals and birds (fig. 19). they may give rise to fatal diseases, but in most cases there is mutual adaptation of host and parasite and they seem to do no harm. one of the most dangerous diseases in man, the african sleeping sickness, is caused by a trypanosome, and the disease of domestic cattle in africa, nagana, or tsetse fly disease, is also so produced. in certain regions of africa where a biting fly, the _glossina morsitans_, occurs in large numbers, it has long been known that cattle bitten by these flies sickened and died, and this prevented the settling and use of the land. in the blood of the sick cattle swarms of trypanosomes are found. the source from which the tsetse fly obtained the trypanosomes which it conveyed to the cattle was unknown until it was discovered that similar trypanosomes exist in the blood of the wild animals which inhabit the region, but these have acquired by long residence in the region immunity or adaptation to the parasite and no disease is produced. with the gradual extension of settlement of the country and the accompanying destruction of wild life the disease is diminishing. some of the inter-relations of infections are interesting. the destruction of wild animals in south africa which, by removing the sources of nagana, rendered the settlement of the country possible was due chiefly to the introduction of another infectious disease, rinderpest, which not only destroyed the wild animals but produced great destruction of the domestic cattle as well. the _sleeping sickness_ has many features of interest. in the old slavery days it was found that the negroes from the congo region in the course of the voyage or after they were landed sometimes were affected with a peculiar disease. they were lethargic, took little notice of their surroundings, slept easily and finally passed into a condition of somnolence in which they took no food and gradually died. there was no extension of the disease and it was attributed to extreme homesickness and depression. a similar disease has been known for more than one hundred years on the west coast of africa, and attracted a good deal of interest and curiosity on account of the peculiar lethargy which it produced and from which it has received the name of "sleeping sickness." although apparently infectious in its native haunts, it lost the power of spreading from man upon removal to regions where it did not prevail. at first confined to a very small region on the niger river, it gradually extended with the development of trade routes and the general increase of communications which trade brings, until it prevails in the entire congo basin, in the british and german possessions in east africa, and is extending north and south of these regions. the cause of the disease and its mode of conveyance was discovered in 1903. the fly _glossina palpalis_ which conveys the disease is a biting fly about the size of the common house fly and lives chiefly in the vicinity of water. when such a fly bites an individual who has sleeping sickness its bite can convey the disease to monkeys, on whom the transmission experiments were made. after biting the fly is infectious for a period of two days. after this it is harmless, unless it again obtains a supply of living trypanosomes. there is quite a period in which there are no symptoms of the disease, although trypanosomes are found in the blood and in the lymph nodes, and the individual is a source of infection. the peculiar lethargy which has given the disease its name does not appear until the nervous system is invaded by the parasites. it is impossible to compute accurately the numbers of deaths from this disease--in the region of victoria nyanza alone the estimates extend to hundreds of thousands. 3. in the third mode of insect conveyance the insect does not play a merely passive rôle, but becomes a part of the disease, itself undergoing infection, and a period in the life cycle of the organism takes place within it. in all these cases quite a period of time must elapse before the insect is capable of transmitting the disease; in malaria, which is the best type of such a disease, this period is ten days. malaria is due to a small protozoan, the _plasmodium malariæ_, which was discovered by lavaran, a french investigator, in 1882. the organism lives within or on the surface of the red blood corpuscles. it first appears as a very minute colorless body with active amoeboid movements, and increases in size, attacks a succession of corpuscles, and finally attains a size as large as or larger than a corpuscle. the corpuscles attacked become pale by the destruction of hæmoglobin, swell up and disintegrate, the hæmoglobin becoming converted into granules of black pigment inside the parasite. having attained a definite size the organism forms a rosette and divides into a number of forms similar to the smallest seen inside the corpuscles; these small forms enter other corpuscles and the cycle again begins. this cycle of development takes place in forty-eight hours, and segmentation is always accompanied by a paroxysm of the disease shown in a chill followed by fever and sweating which is due to the effect of substances liberated by the organism at the time of segmentation. a patient may have two crops of the parasite developing independently in the blood, and the two periods of segmentation give a paroxysm for each, so that the paroxysms may appear at intervals of twenty-four hours instead of forty-eight (fig. 20). this cycle of development may continue for an indefinite time, and there may be such a rapid increase in the parasites as to bring about the death of the individual; but with him the parasite would also perish, for there would be no way of extending the infection and providing a new crop. the disease has been transmitted by injecting the infected blood into a normal individual. [illustration: fig. 20.--part of the cycle of development of the organism of malaria, _a-g_, cycle of forty-eight hour development, the period of chill coinciding with the appearance of _f_ and _g_ in the blood. the organisms _g_, which result from segmentation, attack other corpuscles and a new cycle begins. _h_, the male form or microgametocyte, with the protruding and actively moving spermatozoa, one of which is shown free. _i_ and _j_ are the macrogametes or female forms. _k_ shows one of these in the act of being fertilized by the entering spermatozoön. the differentiation into male and female forms takes place in the blood, the further development of the sexual cycle within the mosquito.] if a mosquito of the species _anopheles_ bites the affected person, it obtains a large amount of blood which contains many parasites. within the mosquito the parasite undergoes a further development into male and female sexual forms, which may also form in the blood, termed respectively _microgametocyte_ and _macrogamete_. from the microgametocyte small flagellate bodies, the male sexual elements _microgametes_ or _spermatozoa_, develop and fertilize the _macrogametes_; after fertilization this develops into a large body, the _oöcyst_ which is attached to the wall of the stomach of the mosquito. within the oöcyst, innumerable small bodies, the sporozoites, develop, make their way into the salivary glands and are injected into the individual who becomes the prey of the mosquito, and again the cycle of development begins. the presence of the parasite within the mosquito does not constitute a disease. so far as can be determined, life goes on in the usual way, and its duration in the insect is not shortened. the nature of the parasite which produces yellow fever is unknown, for it belongs to the filterable viruses; the infectious material, however, has been shown by inoculation to exist in the blood, and the disease is transmitted by a mosquito of another species, the _stegomyia_. the development cycle within this takes a period of twelve days, which time must elapse after the mosquito has bitten before it can transmit the disease. here again the mutual interdependence of knowledge is shown. nothing could have seemed less useful than the study of mosquitoes, the differentiation of the different species, their mode of life, etc., and yet without this knowledge discoveries so beneficial and of such far-reaching importance to the whole human race as that of the cause and mode of transmission of malaria and yellow fever would have been impossible; for it could easily have been shown that the ordinary _culex_ mosquito played no rôle. the rôle which insects may play in the transmission of disease was first shown by theobald smith in this country, in the transmission by a tick of the disease of cattle known as texas fever. the infecting organism _pyrosoma bigenimum_ is a tiny pear-shaped parasite of the red corpuscles. smith's investigations on the disease, published in 1893, is one of the classics in medicine, and one of the few examples of an investigation which has not been changed or added to by further work. one of the most interesting methods of extension of infection, showing on what small circumstances infection may depend, is seen in the case of the hookworm disease, which causes such devastation in the southern states. the organism which produces the disease, the _uncinaria_, belongs to the more highly developed parasites, and is a small round worm one-third of an inch long. the worms which inhabit the intestines have a sharp biting mouth by which they fasten themselves to the mucous membrane and devour the blood. the most prominent symptom of the disease is anæmia, or loss of blood, due not only to the direct eating of the parasite, but to bleeding from the small wounds caused by its bite. large numbers of eggs are produced by the parasite which are passed out with the feces, which becomes the only infectious material. in a city provided with water-closets and a system of sewerage there would be no means of extension of infection. the eggs in the feces in conditions of warmth and moisture develop into small crawling larvæ which can penetrate the skin, producing inflammation of this, known in the region as the ground itch. the larvæ enter the circulation and are carried to the lungs, where they perforate the capillaries and reach the inner surface; from this they pass along the windpipe, and then by way of the gullet and stomach reach their habitat, the small intestine. unfortunately, the habits and poverty of the people in every way facilitate the extension of the infection. there is no proper disposal of the feces, few of the houses have even a privy attached to them, and the feces are distributed in the vicinity of the houses. this leads to contamination of the soil over wide areas. most of the inhabitants of the country go barefoot the greater part of the year, and this gives ready means of contact with the larvæ which crawl over the surface of the ground. the disease is necessarily associated with poverty and ignorance, the amount of blood is reduced to a low point, and industry, energy and ambition fall with the blood reduction; the schools are few and inefficient; the children are backward, for no child can learn whose brain cells receive but a small proportion of the necessary oxygen; and a general condition of apathy and hopelessness prevails in the effected communities. the control of the disease depends upon the disinfection of the feces, or at least their disposal in some hygienic method, the wearing of shoes, and the better education of the people, all of which conditions seem almost hopeless of attainment. the infection is also extended by means of the negroes who harbor the parasite, but who have acquired a high degree of immunity to its effects and whose hygienic habits are even worse than those of the whites. the organism was probably imported with the negroes from africa and is one of the legacies of slavery. the diseases of animals are in many ways closely linked with those of man. in the case of the larger parasites, such as the tapeworms and the trichina, there is a direct interchange of disease with animals, certain phases of the life cycle of the organisms are passed in man and others in various of the domestic animals. a small inconspicuous tapeworm inhabits the intestine of dogs and seems to produce no ill effects. the eggs are passed from the dog, taken into man, and result in the formation of large cystic tumors which not infrequently cause death. where the companionship between dog and man is very close, as in iceland, the cases are numerous. most of the diseases in animals caused by bacteria and protozoa are not transmitted to man, but there is a conspicuous exception. plague is now recognized as essentially an animal disease affecting rats and other small rodents, and from these the disease from time to time makes excursions to the human family with dire results. the greatest epidemics of which we have any knowledge are of plague. in the time of justinian, 542 b.c., a great epidemic of plague extended over what was then regarded as the inhabited earth. this pandemic lasted for fifty years, the disease disappeared and appeared again in many places and caused frightful destruction of life. cities were depopulated, the land in many places reverted to a wilderness, and the works of man disappeared. the actual mortality cannot be known, but has been estimated at fifty millions. plague played a large part in the epidemics of the middle ages. an epidemic started in 1346 and had as great an extension as the justinian plague, destroying a fourth of the inhabitants of the places attacked; and during the fifteenth and sixteenth and seventeenth centuries the disease repeatedly raised its head, producing smaller and greater epidemics, the best known of which, from the wonderful description of de foe, is that of london in 1665, and called the black death. little was heard of the disease in the nineteenth century, although its existence in asia was known. in 1894 it appeared in hong kong, extended to canton, thence to india, japan, san francisco, mexico, and, in fact, few parts of the tropics or temperate regions of the earth have been free from it. mortality has varied greatly, being greatest in china and in india; in the last the estimate since 1900 is seven million five hundred thousand deaths. the disease is caused by a small bacillus discovered in 1894 which forms no spores and is easily destroyed by sunlight, but in the dark is capable of living with undiminished virulence for an indefinite time. the disease in man appears in two forms, the most common known as bubonic plague, from the great enlargement of the lymph nodes, those of the groin being most frequently affected. the more fatal form is known as pneumonic plague, and in this the lungs are the seat of the disease. in the old descriptions of the disease it was frequently mentioned that large numbers of dead rats were found when it was prevalent, and the most striking fact of the recent investigations is the demonstration that the infection in man is due to transference of the bacillus from infected rats. there are endemic foci of the disease where it exists in animals, the present epidemic having started from such a focus in northern china, in which region the _tarabagan_, a small fur-bearing animal of the squirrel species, was infected. rats are easily infected, the close social habits of the animal, the vermin which they harbor, and the habits of devouring their dead fellows favor the extension of infection. the disease extends from the rat to man chiefly by means of the fleas which contain the bacilli, and in cases of pneumonic plague from man to man by means of sputum infection. the disease once established in animals tends to remain, the virus being kept alive by transmission from animal to animal, and the persistence of the infection is favored by mild and chronic cases. chapter ix disease carriers.--the relation between sporadic cases of infectious disease and epidemics.--smallpox.--cerebro-spinal meningitis.--poliomyelitis.--variation in the susceptibility of individuals.--conditions which may influence susceptibility.--racial susceptibility.--influence of age and sex.--occupation and environment.--the age period of infectious diseases. we have seen that insects serve as carriers of disease in two ways: in one, by becoming contaminated with organisms they serve as passive carriers, and in the other they undergo infection and form a link in the disease. the more recent investigations of modes of transmission of infectious diseases have shown that man, in addition to serving while sick as a source of infection, may serve as a passive carrier in two ways. for infection to take place not only must the pathogenic organism be present, but it must be able to overcome the passive and active defences of the body and produce injury. pathogenic organisms may find conditions favorable for growth on the surfaces of the body, and may live there, but be unable to produce infection, and the individual who simply harbors the organisms can transmit them to others. such an individual may be a greater source of infection than one with the disease, because there is no suspicion of danger. the organisms which thus grow on the surfaces have in some cases been shown to be of diminished virulence, but in others have full pathogenic power. such passive carriers of infection have been found for a number of diseases, as cerebro-spinal meningitis, diphtheria, poliomyelitis and cholera. in all these cases the organisms are most frequently found in those individuals who have been exposed to infection as members of a family in which there have been cases of disease. the other sort of carrier has had and overcome the disease, but mutual relations have been established with the organism which continues to live in the body cavity. diphtheria bacilli usually linger in the throat after convalescence is established, and until they have disappeared the individual is more dangerous than one actually sick with the disease. health officers have recognized this in continuing the quarantine against the disease until the organism disappears. in typhoid fever bacilli may remain in the body for a long time and be continually discharged, as in the well-known case of "typhoid mary."[1] single cases of certain infectious diseases may appear in a community year after year, and at intervals the cases become so numerous that the disease is said to be epidemic. such a disease is smallpox. this is a highly infectious disease, towards which all mankind is susceptible. complete protection against the disease can be conferred by jenner's discovery of vaccination. the disease becomes modified when transferred to cattle, producing what is known as cowpox, in which vesicles similar to those of smallpox appear on the skin. the inoculation of man with the contents of such a vesicle produces a mild form of disease known as vaccinia, which protects the individual from smallpox. this protection is fully as adequate as that produced by an attack of smallpox, and we are warranted in saying that if thorough vaccination, or the inoculation with vaccinia, were carried out smallpox would disappear. there are great difficulties in the way of carrying out effective vaccination of the whole population, which are accentuated by the active opposition of people who are ignorant and wilfully remain so. there exists in every state a number of people unprotected by vaccination, and among these single cases of smallpox appear. the unprotected individuals gradually increase in number, forming an inflammable material awaiting the spark or infection which produces a conflagration in the one case and an epidemic in the other. cerebro-spinal meningitis is another example of a disease which exists in sporadic and epidemic form. this disease is caused by a small micrococcus, the organisms joined in pairs. the seat of the disease is in the meninges or membranes around the brain and spinal cord. the micrococci enter the body from the throat and nose, and either pass directly from here into the meninges, or they enter into the blood and are carried by this into the meninges. the organisms are easily destroyed and cannot long survive the conditions outside the body, so that for infection to take place the transmission must be very direct. carriers who have the organisms in the throat, but who do not have the disease, are the principal agents in dissemination. the mortality is high, and even in recovery permanent damage is often done to the brain or to the organs of special sense. sporadic cases constantly occur in small numbers, and it is difficult or impossible to trace any connection between these cases. at varying intervals, often twenty years intervening, an epidemic appears which sometimes remains local in a city or state, sometimes extends to adjoining cities or states, and may even extend over a very large area. in the epidemics the mortality is much higher than in the sporadic cases. the same explanation given for smallpox cannot apply here, for there is not a similar accumulation of susceptible material. we know there is a great deal of variation in the virulence of the different pathogenic organisms, and the virulence can be artificially increased and diminished. in epidemics of meningitis the virulence of the organisms is increased, as is shown by the greater mortality. it is highly probable that such epidemics are due to changes which arise in the organisms from causes we do not know and which increase their capacity for harm. it is possible that such a change would convert a carrier into a case of disease, the organism acquiring greater powers of invasion. such a strain of organisms arising in one place and producing an epidemic could be transported to another locality and exert the same action, or similar changes in the organisms could arise simultaneously in a number of places. analogies to such conditions are given in plants. in certain plants it has been shown that from unknown causes there appears a tendency to the production of variations. a very beautiful herbaceous peony known as "bridesmaid" after having grown for a number of years in single form, in one year wherever grown suddenly became double. the peculiar thing with the lower unicellular organisms is that the changes which so arise do not tend to become permanent, the organism reverts to its usual character, the disease to its sporadic type. a very fatal form of poliomyelitis has for a number of years prevailed in sweden. in the united states there have been continually a number of single cases of the disease, and it is not impossible that a more pathogenic strain of the organism has developed in sweden and has been imported into this country, giving rise to the much greater extension of the disease in a number of places. the most cursory study of the infectious diseases shows that there is great variation in the susceptibility of individuals. even in the most severe epidemics all are not equally affected, some escape the infection, others have the disease lightly, others severely, some die. chance enters into this, but plays a small part, for the same varying individual susceptibility is shown experimentally. if a given number of animals of the same species, age and weight, even those from the same litter, be inoculated with a given number of bacteria shown to be pathogenic for that species, the results differ. if the dose be necessarily fatal, death will take place at intervals; if a dose smaller than the fatal be used, some animals will die, others will recover. the defences of the organism being centred in the activity of the living tissue, any condition which depresses cell activity may have an effect in increasing susceptibility to infection. animals which ordinarily are not susceptible to infection with a certain organism may be made so by prolonged hunger, or fatigue, by the influence of narcotics, by reduction of the body temperature, by loss of blood. in man prolonged fatigue, cold, the use of alcohol to excess and even psychic depression increases susceptibility. it has been shown that such conditions are accompanied by a diminution in the power of the blood to destroy bacteria. there is variation in the susceptibility to infection in the different races of man. if a race be confined to one habitat with close intercourse between the people, such a race may acquire a high degree of immunity to local diseases by a gradual weeding out of the individuals who are most susceptible. a degree of comparative harmony may be gradually established between host and parasite, as is the case in wild animals. these have few diseases, the weak die, the resistant breed; they harbor, it is true, large numbers of parasites, but there is mutual adjustment between parasite and host. diseases in animals greatly increase under the artificial conditions of domestication. certain highly specialized breeds of cattle, as the alderneys, are much more susceptible to tuberculosis than the less specialized. the high development of the variation which consists in a marked ability to produce milk fat is probably combined with other qualities, shown in diminished resistance to disease, and under natural conditions the variation would not have persisted. the introduction of a new disease into an isolated people has often been attended with dire consequences. it is much the same thing with the introduction of disease of plants. in europe the brown-tail moth and the gypsy moth produce continuously a certain amount of damage to the trees, but their parasitic enemies have developed with them and check their increase. these pests were brought to this country in which there were no conditions retarding their increase and have produced great damage. it is very difficult to estimate the degree of racial susceptibility. the negro race seems to be more susceptible to certain diseases, such as tuberculosis and smallpox, less so to others, as yellow fever, malaria and uncinariasis. what are apparently differences in susceptibility may be explained by racial customs. a statistical inquiry into death in india from poisonous snakes might be interpreted as showing a marked resistance on the part of the white to the action of the venom, but it is merely a question of the boots of the whites and the naked feet and legs of the natives. the relatively greater frequency of smallpox in the blacks is due to the greater difficulties in carrying out vaccination measures among them and the greater opportunity for infection which results from their less hygienic life. it has always been noted that when plague prevails in oriental cities, the natives are more frequently attacked than are europeans. this does not depend upon differences in susceptibility, but on the better hygienic conditions of the whites which prevent the close relation to rats and vermin by which infection is extended. there would be but little extension of the hookworm disease in a community where shoes were worn and the habits were cleanly. it is by no means improbable that the formation of the habits of civilization was influenced by infection. most of these habits, such as personal cleanliness, the avoidance of close contact, the demand for individual utensils for eating and drinking, are all of distinct advantage in opposing infection. certain habits, on the other hand, such as kissing, which probably represents the extension of a habit of sexual origin, are disadvantageous and infection is often transmitted in this way. in syphilitic infection the mouth forms one of the most common localizations of the disease and may contain the causal organisms in great numbers. this, the _spirochæta pallida_, is an organism of great virulence, and man is the most susceptible animal. the disease, like gonorrhoea, is essentially a sexual disease, the primary location is in the sexual organs, and it is transmitted chiefly by sexual contact. of all the infectious diseases, it is the one most frequently transmitted to the unborn child; in certain cases the disease is transmitted, in others the developing foetus may be so injured by the toxic products of the disease that various imperfections of development result, as is shown in deformities, or in conditions which render the entire organism or individual organs, particularly the nervous system, more susceptible to injury. following the primary localization of the acquired form of the disease, there is usually secondary localization in the mucous membrane of the mouth, and the disease may be transmitted by kissing or by the use of contaminated utensils. the habit of indiscriminate kissing is one which might with great benefit be given up. there is definite relation between age and the infectious diseases. in general, susceptibility is increased in the young; young animals can be successfully inoculated with diseases to which the adults of the species are immune, and certain human diseases, such as scarlet fever, measles and whooping cough, seem to be the prerogatives of the child. it must be remembered, however, that one attack of these diseases confers a strong and lasting immunity and children represent a raw material unprotected by previous disease. where measles has been introduced into an island population for the first time, all ages seem equally susceptible. all ages are equally susceptible to smallpox, and yet in the general prevalence of the disease in the prevaccination period it was almost confined to children, the adults being protected by a previous attack. the habits and environment at different ages have an influence on the opportunities for infection. there is comparatively little opportunity for infection during the first year, in which period the infant is nursed and has a narrow environment within which infection is easily controlled. with increasing years the opportunities for infection increase. when the child begins to move and crawl on hands and knees the hands become contaminated, and the habit of putting objects handled into the mouth makes infection by this route possible. food also becomes more varied, milk forms an important part of the diet, and we are now appreciating the possibilities of raw milk in conveying infection. with the enlarging environment, with the school age bringing greater contact of the child with others, there come greater opportunities for infection which are partly offset by the increase in cleanliness. the dangers of infection in the school period are now greatly lessened by medical inspection and care of the school children. in the small epidemic of smallpox which prevailed in boston from 1881 to 1883, there was a sharp decline in the incidence of the disease in children as soon as the school age was reached, this being due to the demand of vaccination as a condition for entrance into the schools. many of the infectious diseases are much milder in children than in adults. this is the case in typhoid fever, malaria and yellow fever. the comparative immunity of the natives to yellow fever in regions where this prevails seems to be due to their having acquired the disease in infancy in so mild a form that it was not recognized as such. the infectious diseases are preëminently the diseases of the first third of life. after the age of forty man represents a select material. he has acquired immunity to many infections by having experienced them. habits of life have become fixed and there is a general adjustment to environment. the only infectious disease which shows no abatement in its incidence is pneumonia, and the mortality in this increases with age. between thirty-five and fifty-five man stands on a tolerably firm foundation regarding health; after this the age atrophies begin, the effects of previous damage begin to be apparent, and the tumor incidence increases. footnote: [1] this was the case of a woman, by occupation a cook, whose numerous exchanges of service were accompanied by the appearance of cases of typhoid fever in the families. this became so marked that an examination was made and she was found to be a typhoid carrier and as such constantly discharging typhoid bacilli. she is now isolated. chapter x inheritance as a factor in disease.--the process of cell multiplication.--the sexual cells differ from the other cells of the body.--infection of the ovum.--intra-uterine infection.--the placenta as a barrier to infection.--variations and mutations.--the inheritance of susceptibility to disease.--the influence of alcoholism in the parents on the descendants.--the heredity of nervous diseases.--transmission of disease by the female only.--hemophilia.-the inheritance of malformations.--the causes of malformations.--maternal impressions have no influence.--eugenics. the question of inheritance of disease is closely associated with the study of infection, and the general subject of heredity in its bearing on disease can be considered here. by heredity is understood the transference of similar characteristics from one generation of organisms to another. the formation of the sexual cells is a much more complex process than that of the formation of single differentiated cells, for the properties of all the cells of the body are represented in the sexual cells, to the union of which the heredity transmission of the qualities of the parents is due. in the nucleus of all the cells in the body there is a material called _chromatin_, which in the process of cell division forms a convoluted thread; this afterwards divides into a number of loops called _chromosomes_, the number of which are constant for each animal species. in cell division these loops divide longitudinally, one-half of each going to the two new cells which result from the division; each new cell has one-half of all the chromatin contained in the old and also one-half of the cytoplasm or the cell material outside of the nucleus. the process of sexual fertilization consists in the union of the male and female sex cells and an equal blending of the chromatin contained in each (fig. 22). in the process of formation of the sexual cells a diminution of the number of chromosomes contained in them takes place, but this is preceded by such an intimate intermingling of the chromatin that the sexual cells contain part of all the chromosomes of the undifferentiated cells from which they were formed. the new cell which is formed by the union of the male and female sexual cells and which constitutes a new organism, contains the number of chromosomes characteristic of the species and parts of all the chromatin of the undifferentiated cells of male and female ancestors. as a result of this the most complicated mechanism in nature, it is evident that in a strict sense there can be no heredity of a disease because heredity in the mammal is solely a matter of the chromosomes and these could not convey a parasite. the new organism can, however, quickly become diseased and, by the transference of disease to it and by either parent, there is the appearance of hereditary transmission of disease, though in reality it is not such. the ovum itself can become the site of infection; this, which was first discovered by pasteur in the eggs of silkworms, takes place not infrequently in the infection of insects with protozoa. in texas fever the ticks which transmit the disease, after filling with the infected blood, drop off and lay eggs which contain the parasites, and the disease is propagated by the young ticks in whom the parasites have multiplied. the same thing is true in regard to the african relapsing or tick fever, which is also transferred by a tick. in the white diarrhoea of chickens the eggs become infected before they are laid and the young chick is infected before it emerges from the shell. it is highly improbable, and there is no certain evidence for it, that the extremely small amount of material contributed by the male can become infected and bring infection to the new organism. in the cases in which disease of the male parent is transferred to the offspring, it is either by an infection of the female by the male, with transference of the infection from her to the developing organism, or with the male sexual cells there may be a transference to the female of the infectious material and the new organism may be directly infected. no other disease in man is so easily and directly transferred from either parent to offspring as is syphilis, and the disease is extremely malignant for the foetus, usually causing death before the normal period of intra-uterine development is reached. [illustration: fig. 21.--diagram showing the relation of the sexual cells to the somatic cells or those of the general body. the sexual cells are represented to the left of the line at the bottom of diagram and are black. from the fertilized ovum at the top there is a continuous cell development, with differentiation represented in the cell groups of the bottom row. it is seen that the sexual cells are formed directly from the germ cell and contain no admixture from the cells of the body.] the mother gives the protection of a narrow and unchanging environment and food to the new organism which develops within the uterus, and there is always a membranous separation between them. disease of the mother may affect the foetus in a number of ways. in most cases the membrane of separation is an efficient guard preventing pathogenic organisms reaching the foetus from the mother. in certain cases, however, the guard can be passed. in smallpox, not infrequently, the disease extends from the mother to the foetus, and the child may die of the infection or be born at term with the scars resulting from the disease upon it. syphilis in the mother in an active stage is practically always extended to the foetus. we have said that in an infectious disease substances of an injurious character are produced by bacteria, and such substances being in solution in the blood of the infected mother can pass through the membranous barrier and may destroy the foetus although the mother recovers from the infection. [illustration: fig. 22.--diagrammatic representation of the process of fertilization. (boveri.) in the first cell (_a_) the ovum is shown in process of fertilization by the entering spermatozoon or male sexual element. in the following cells there is shown the increase in amount of the male material and the final intimate commingling in _g_ which precedes the first segmentation. _g_ represents a new organism formed by the union of the male or female cell but differing from either of them.] living matter is always individual, and this individuality is expressed in slight structural variations from the type of the species as shown in an average of measurements, and also in slight variations in function or the reactions which living tissue shows towards the conditions acting upon it. the anatomical variations are more striking because they can be demonstrated by weight and measure, but the functional variations are equally numerous. thus, no two brains react in exactly the same way to the impressions received by the sense organs; there are differences in muscular action, differences in digestion; these variations in function are due to variations in the structure of living material which are too minute for our comparatively coarse methods of detection. in the enormous complexity of living matter it is impossible that there should not be minute differences in molecular arrangement and to this such functional variations may be due. chemistry gives us a number of examples of variations in the reaction of substances which with the same composition differ in the molecular arrangement. even in so simple a mechanism as a watch there are slight differences in structure which gives to each watch certain individual characteristics, but the type as an instrument constructed for recording time remains. in the fusion of the chromosomes of the male and female sexual cells, to which the hereditary transmission of the ancestral qualities to the new offspring is due, there are differences in the qualities of each, for the individuality of the parents is expressed in the germ cells, and the varying way in which these may fuse gives to the new cell qualities of its own in addition to qualities which come from each ancestor, and from remote ancestors through these. the qualities with which the new organism starts are those which it has received from its ancestors plus its individuality. the fact that the sexual cells are formed from the early formed cells of the new organism which represent all of the qualities of the fertilized ovum or primordial cell, renders it unlikely that the new offspring will contain qualities which the parents have acquired. the question of the inheritance of characteristics which the parents have acquired as the result of the action of environment upon them is one which is still actively investigated by the students of heredity, but the weight of evidence is opposed to this belief. in the new organism the type of the species is preserved and the variations from the mean to which individuality is due are slight. we are accustomed to regard as variations somewhat greater departures from the species type than is represented in individuality, but there is no sharp dividing line between them. very much wider departures from the species type are known as mutations. such variations and mutations, like individuality, may be expressed in qualities which can be weighed and measured, or in function, and all these can be inherited; certain of them known as dominant characteristics more readily than others, which are known as recessive. if these variations from the type are advantageous, they may be preserved and become the property of the species, and it is in this way that the characteristics of the different races have arisen. certain of the variations are unfavorable to the race. the varying predisposition to infection which undoubtedly exists and may be inherited represents such a variation. tuberculosis is an instance of this; for, while the cause of the disease is the tubercle bacillus, there is enormous difference in the resistance of the body to its action in different individuals. the disease is to a considerable extent one of families, but while this is true the degree of the influence exerted by heredity can be greatly overestimated. the disease is so common that in tracing the ancestry of tuberculous patients it is rare to find the disease not represented in the ancestors. a further difficulty is that the environment is also inherited. the child of a tuberculous parent has much better opportunity to acquire the infection than a child without such an environment [page 167]. other diseases than the infectious seem to be inherited, of which gout is an example. in gout there is an unusual action of the cells of the body which leads to the formation and the retention in the body of substances which are injurious. here it is not the disease which is inherited, but the variation in structure to which the unusual and injurious action of the cells is due. while tuberculosis and gout represent instances in which, although the disease itself is not inherited yet the presence of the disease in the ascendants so affects the germinal material that the offspring is more susceptible to these particular diseases, much more common are the cases in which disease in the parents produces a defective offspring, the defect consisting in a general loss of resistance manifested in a variety of ways, but not necessarily repeating the diseased condition of the parent. in these cases the disease in the parents affects all the cells of the body including the germinal cells, and the defective qualities in the germ cells will affect the cells of the offspring which are derived from these. there is a tendency in these cases to the repetition in the offspring of the disease of the parents, because the particular form of the parental disease may have been due to or influenced by variation of structure. one of the best examples of affection of the offspring by diseased conditions of the parents produced by a toxic agent which directly or indirectly affects all the cells of the body is afforded by alcohol when used in excess. since drunkenness has become a medical rather than a moral question, a great deal of reliable data has accumulated in regard to it as a factor in the heredity of disease. grotjahn gives the following examples: six families were investigated in which there were thirty-one children. in all these families the father and grandfather on the father's side were chronic alcoholics, and in certain of the families drunkenness prevailed in the more remote ancestors. the following was the fate of the children: eight died shortly after birth of general weakness, seven died of convulsions in the first month, three were malformed, three were idiotic, three were feeble-minded, three were dwarfs, three were epileptics, two were normal. in a second group of three families there were twenty children. the fathers were drunkards, but their immediate ancestors were free: four children died of general weakness, three of convulsions in the first month, two were feeble-minded, one was a dwarf, one was an epileptic, seven were normal. in a family in which both father and mother and their ancestors were drunkards there were six children: three died of convulsions within six months, one was an idiot, one a dwarf, and one an epileptic. for comparison there were taken from the same station in life ten families in which there was no drunkenness: three children died from general weakness, three from intestinal troubles, two of nervous affection, two were feeble-minded, two were malformed, fifty were normal. legrain has studied on a larger scale the descendants of two hundred and fifteen families of drunkards in which there were eight hundred and nineteen children. one hundred and forty-five of these were insane, sixty-two were criminals, and one hundred and ninety-seven drunkards. of course all this cannot be attributed to alcohol alone. there is first to be considered a probable variation in the nervous system which is expressed in the alcoholic habit; second, the environment consisting in poverty, bad associates, etc., which the alcoholic habit brings; third, the alcohol alone. that defective inheritance so frequently takes the form of alcoholism is largely due to the environment. there has never been the opportunity to study on a large scale the effect of the complete deprivation of alcohol from a people living in the environment of modern civilization. there is a possibility, and even probability, that the defective nervous organization which predisposes to alcoholism would seek satisfaction in the use of some other sedative drug. so complex are all the interrelations of the social system that it would be possible to regard alcohol as an agent useful in removing the defective, were it not for its long-enduring action and its effects on the descendants, procreation not being affected by its use. diseases of the nervous system are particularly apt to affect the offspring, and often the inherited condition repeats that of the parents. this is due to the fact that most of the nervous diseases depend both upon intrinsic factors which consist in some defective condition of the nervous system representing a variation, and extrinsic factors due to environment or occupation which make the basal condition operative. the definite relation between alcoholism and insanity is due to alcohol acting not as an intrinsic but an extrinsic factor, bringing into effectiveness the hereditary weakness of the nervous system. the influence of heredity in producing insanity is variously estimated at from twenty-six per cent to sixty per cent of all cases. this great difference in the estimation of the hereditary influence is due to the personal equation of the statistician, and the care with which other factors are eliminated. in the more severe form of the hereditary degeneration the same pathological conditions are repeated in the descendants. in certain cases the severity of the condition increases from generation to generation. according to morel there may be merely what is recognized as a nervous temperament often associated with moral depravity and various excesses in the first generation; in the second, severe neuroses, a tendency to apoplexy and alcoholism; in the third, psychic disturbances, suicidal tendencies and intellectual incapacity; and in the fourth, congenital idiocy, malformations and arrests of development. there are some very definite data with regard to inheritance in the nervous disease known as epilepsy. the essential condition in this consists in attacks of unconsciousness, usually accompanied by a discharge of nerve force shown in convulsions, the attack being often preceded by peculiar sensations of some sort known as the aura. in the most marked forms of the affection heredity plays but little part, owing to the early supervention of imbecility and helplessness, and it is a greater factor in the better classes of society than in the proletariat. in the better classes, owing to the greater care of the cases and the avoidance of exciting causes of the attacks, the disease is better controlled and rarely advances to the extent that it does among the poor. the association of epilepsy and alcoholism is especially dangerous, for a slight amount of alcohol may greatly accentuate the disease. in five hundred and thirty-five children in whose parentage there were sixty-two male and seventy-four female epileptics, twenty-two were born dead, one hundred and ninety-five died from convulsions in infancy, twenty-seven died in infancy from other causes, seventy-eight were epileptics, eleven were insane, thirty-nine were paralyzed, forty-five were hysterical, six had st. vitus's dance, one hundred and five were ordinarily healthy. that variations in the nervous system which produce more or less unusual mental peculiarities and which do not take the form of nervous disease are inherited, the most superficial consideration shows. a child in its mental characteristics is said to take after one or the other of its parents, certain habits and mental traits are the same, often even the handwriting of a child resembles that of a parent. in certain cases the inheritance is transmitted by the female alone. this is the case in the hæmophilia, the unfortunate subjects of which are known as bleeders. there is in this a marked tendency to hæmorrhage which depends upon an alteration in the character of the blood which prevents clotting. this, the natural means of stopping bleeding from small wounds, being in abeyance, fatal hæmorrhage may result from pulling a tooth or from an insignificant wound. there is a seeming injustice in the inheritance, for the females do not suffer from the disease although they transmit it, while the males who have the disease cannot even create additional sympathy by transmitting it. the most obvious inheritance is seen in the case of malformations. these represent wide departures from the type of the species as represented in the form. there is no hard and fast line separating the slight departures from the normal type known as variations and mutations, from the malformations. certain of the malformations known as monstrosities hardly represent the human type. these are the cases in which the foetus is represented in a formless mass of tissue, or there is absence of development of important parts such as the nervous system or there is more or less extensive duplication of the body. there has always been a great deal of popular interest attached to the malformations owing to the part which maternal impressions are supposed to play in their production. in this, some striking impression made on the pregnant woman is supposed to affect in a definite way the structure of the child. the cases, for instance, in which a woman sees an accident involving a wound or a loss of an arm and the child at birth shows a malformation involving the same part. there is no association between maternal impressions and malformations, although there have been many striking coincidences. all malformations arise during the first six weeks of pregnancy known as the embryonic period, in which the development of the form of the child is taking place, and during which time there is little consciousness of pregnancy. maternal impressions are usually received at a later period, when the form of the child is complete and it is merely growing. it must be remembered also that there is neither nervous nor vascular connection between the child in the uterus and the mother, the child being from the period of conception an independent entity to which the mother gives nutriment merely. of course, as has been said, the mother may transmit to the child substances which are injurious, and in certain cases parasites may pass from the mother to the foetus. the same types of malformations which occur in man are also seen in birds, and it would require a more vigorous imagination than is usual to believe that a brooding hen could transmit an impression to an egg and that a headless chick could result from witnessing the sacrifice of an associate. the idea of the importance of maternal impressions in influencing the character of the offspring is a very old one, a well-known instance being the sharp practice of jacob's using peeled wands to influence the color of his cattle. in regard to coincidences the great number of cases in which strong impressions made on the mind of the pregnant mother without result on the offspring are forgotten. the belief has been productive of great anxiety and even unhappiness during a period which is necessarily a trying one, and should be dismissed as being both theoretically impossible and unsupported by fact. the malformations are divided anatomically into those characterized, first, by excess formation, second, by deficient formation, third, by abnormal displacement of parts. they are due to intrinsic causes which are in the germ, and which may be due to some unusual conditions in either the male or female germ cell or an imperfect commingling of the germinal material, and to extrinsic causes which physically, as in the nature of a shock or chemically as by the action of a poison, may affect the embryo through the mother. malformations are made more numerous in chickens by shaking the eggs before brooding. a number of malformations are produced by accidental conditions arising in the environment; for instance, the vascular cord connecting mother and child may become wound around parts constricting them or even cutting them off, and the membrane around the child may become adherent to certain parts and prevent the development of these. the extrinsic causes are more operative the more unfavorable is the environment of the mother. malformations are more common in illegitimate children than in legitimate and more common in alcoholic mothers; there is an unfavorable environment of poverty in both cases, added to in the latter and usually in the former by the injurious action of the alcohol. the more extensive malformations have no effect on heredity, because the subjects of them are incapable of procreation. the malformations which arise from the accidents of pregnancy and which are compatible with a perfectly normal germ are in the nature of acquired characteristics and are not inherited. those malformations, however, which are due to qualities in the germinal material itself are inherited, and certain of them with remarkable persistence. there are instances in which the slight malformation consisting in an excess of fingers or toes has persisted through many generations. it may occasionally lapse in a generation to reappear later. in certain cases, notably in the bleeders, the inheritance is transmitted by the female alone, in other cases by the sexes equally, but there are no cases of transmission by the male line only. it is evident that when the same malformation affects both the male and the female line the hereditary influence is much stronger. a case has been related to me in which most of the inhabitants in a remote mountain valley in virginia where there has been much intermarriage have one of the joints of the fingers missing. there is a very prevalent idea that in close intermarriage in families variations and malformations often unfortunate for the individual are more common. all experimental evidence obtained by interbreeding of animals shows that close interbreeding is not productive of variation, but that variations existing in the breed become accentuated. variations either advantageous or disadvantageous for the race or individual may either of them become more prevalent by close intermarriage. it seems, however, to have been shown by the customs of the human race that very close intermarriage is disadvantageous. eugenics, which signifies an attempt at the betterment of the race by the avoidance of bad heredity, has within recent years attracted much attention and is of importance. some of its advocates have become so enthusiastic as to believe that it will be possible to breed men as cattle and ultimately to produce a race ideally perfect. it is true that by careful selection and regulation of marriage certain variations, whether relating to coarse bodily form or to the less obvious changes denoted by function, can be perpetuated and strengthened. that the semitic race excels in commerce is probably due to the fact that the variation of the brain which affected favorably the mental action conducive to this form of activity, was favorable for the race in the hostile environment in which it was usually placed and transmitted and strengthened by close intermarriage. it is impossible, however, to form a conception of what may be regarded as an ideal type of the human species. the type which might be ideal in a certain environment might not be ideal in another, and environment is probably of equal importance with the material. the eugenics movement has enormously stimulated research into heredity by the methods both of animal experimentation and observation, and study of heredity in man. as in all of the beginning sciences there is not the close inter-relation of observed facts and theory, but there is excess of theory and dearth of facts. certain considerations, however, seem to be evident. it would seem to be evident that individuals should be healthy and enabled to maintain themselves in the environment in which they are placed, but the qualities which may enable an individual successfully to adapt himself to factory life, or life in the crowds and strong competition of the city, may not be, and probably are not, qualities which are good for the race in general or for his immediate descendants. at present our attempts to influence heredity should be limited to the heredity of disease only. we can certainly say that intermarriage between persons who have tuberculosis or in whose families the disease has prevailed is disadvantageous for the offspring; the same holds true for insanity and for nervous diseases of all sorts, for forms of criminality, for alcoholism, and for those diseases which are long enduring and transmitted by sexual contact such as syphilis and gonorrhoea. it is of importance that the facts bearing on the hereditary transmission of disease should become of general knowledge, in order that the dangers may be known and voluntarily avoided. no measures of preventive medicine are successful which are not supported by a public educated to appreciate their importance, and the same holds true of eugenics. how successful will be public measures leading to the prevention of offspring in the obviously unfit by sterilization of both males and females is uncertain. it is doubtful whether public sentiment at the present time will allow the measure to be thoroughly carried out. some results in preventing unfit heredity may be attained by the greater extension of asylum life, but the additional burden of this upon the labor of the people would be difficult to bear. at best such measures would only be carried out in the lower class of society. chapter xi chronic diseases.--disease of the heart as an example.--the structure and function of the heart.--the action of the valves.--the production of heart disease by infection.--the

diseases are diseases of long duration and which do not tend to result in complete recovery; in certain cases a cause of disease persists in the body producing constant damage, or in the course of disease some organ or organs of the body are damaged beyond the capacity of repair, and the imperfect action of such damaged organs interferes with the harmonious inter-relation of organs and the general well-being of the body. the effect of damage in producing chronic disease may not appear at once, for the great power of adaptation of organs and the exercise of reserve force may for a time render the damage imperceptible; when, however, age or the supervention of further injury diminishes the power of adaptation the condition of disease becomes evident. chronic disease may be caused by parasites when the relation between host and parasite is not in high degree inimical, as in tuberculosis, gonorrhoea, syphilis, most of the trypanosome diseases and the diseases produced by the higher parasites. in certain cases the chronic disease represents really a series of acute onsets; thus in the case of the parasites there may be periods of complete quiescence of infection but not recovery, the parasites remaining in the body and attacking when the defences of the body are in some way weakened. in such cases there may be temporary immunity produced by each excursion of the disease, but the immunity is not permanent nor is the parasite destroyed. there is a further connection between chronic disease and infection in that the damage to the organs, which is the great factor underlying chronic disease, is so often the result of an infection. the infectious diseases are those of early life; chronic disease, on the other hand, is most common in the latter third of life. this is due to the fact that in consequence of the general wear of the body this becomes less resistant, less capable of adaptation, and organic injury, which in the younger individual would be in some way compensated for, becomes operative. the territory of chronic disease is so vast that not even a superficial review of the diseases coming under this category can be attempted in the limits of this book, and it will be best to give single examples only, for the same general principles apply to all. one of the best examples is given in chronic disease of the heart. the heart is a hollow organ forming a part of the blood vascular system and serving to give motion to the blood within the vessels by the contraction of its strong muscular walls. it is essentially a pump, and, as in a pump, the direction which the fluid takes when forced out of its cavity by the contraction of the walls diminishing or closing the cavity space, is determined by valves. the contraction of the heart, which takes place seventy to eighty times in a minute, is automatic and is due to the essential quality of the muscle which composes it. the character, frequency and force of contraction, however, can be influenced by the nervous system and by the direct action of substances upon the heart muscle. the heart is divided by a longitudinal partition into a right and left cavity, and these cavities are divided by transverse septa, with openings in them controlled by valves, each into two chambers termed _auricle_ and _ventricle_. the auricle and ventricle on each side are completely separated. the circulation of the blood through the heart is as follows: the blood, which in the veins of the body is flowing towards the heart, passes by two channels, which respectively receive the blood from the upper and lower part of the body, into the right auricle. when this becomes distended it contracts, forcing the blood into the right ventricle; the ventricle then contracts and sends the blood into the arteries of the lungs, the passage of blood into the auricle being prevented by valves which close the opening between auricle and ventricle when the latter contracts upon its contents. when the ventricle empties by its contraction the wall relaxes and the back flow from the artery is prevented by crescentic-shaped valves placed where the artery joins the ventricle. a similar arrangement of valves is on the left side of the heart. the pressure given the blood by the contraction of the right ventricle sends it through the lungs; from these, after it has been oxygenated, it passes into the left auricle, then into the left ventricle and from this into the great artery of the body, the aorta, which gives off branches supplying the capillaries of all parts of the body. both of the auricles and both of the ventricles contract at the same, time, the ventricular contraction following closely upon the contraction of the auricles. contraction or systole is followed by a pause or diastole during which the blood flows from the veins into the auricles. the work which the right ventricle accomplishes is very much less than that of the left, and the right ventricle has a correspondingly thinner wall. the size of the heart is influenced by the size and the occupation of the individual being larger in the large individual than in the small, and larger in the active and vigorous than in the inactive. generally speaking, the heart is about as large as the closed fist of its possessor. imperfections of the heart which interfere with its action may be the result of failure of development or disease. an imperfect heart which can, however, fully meet the limited demands made upon it in intra-uterine life, may be incapable of the work placed upon it in extra-uterine life. children with imperfectly formed hearts may be otherwise perfect at birth, but they have a bluish color due to the imperfect supply of the blood with oxygen, and are known as blue babies. the condition becomes progressively worse due to the progressive demands made upon the heart, and death takes place after some days or months or years, the time depending upon the degree of the imperfection. much of the damage of the heart in later life is due to infection. the valves of the heart are a favorite place for attack by certain sorts of bacteria which get into the blood. this is due to the prominent position of the valves which brings them in contact with all the blood in the body, the large extent and unevenness of the surface and to the rubbing together and contact of their edges when closed. at the site of infection there is a slight destruction of tissue and on this the blood clots producing rough wart-like projections. the valves in some cases are to a greater or less extent destroyed, they may become greatly thickened and by the deposit of lime salts converted into hard, stony masses. essentially two conditions are produced. in one the thickened, unyielding valves project across the openings they should guard, and thus by constricting the opening interfere with the passage of blood either through the heart or from it. in the other the valves are so damaged that they cannot properly close the orifices they guard, and on or after the contraction of the cavities there is back flow or regurgitation of the blood. if, for instance, the orifice of the heart into the aorta is narrowed, then the left ventricle can only accomplish its work of projecting into the aorta a given amount of blood in a given time by contracting with greater force and giving a greater rapidity to the stream passing through the narrow orifice. this the heart can do because, like all other organs of the body, it has a large reserve force which enables it, even suddenly, to meet demands double the usual, and like all other muscles of the body it becomes larger and stronger by increased work. the condition here is much simpler than when the same valve is incapable of perfect closure, or when both obstruction and imperfect closure, are combined as they not infrequently are. in such cases the ventricle must do more than in the first case. it must force through the orifice, which may be narrowed, the amount of blood which is necessary to keep up the pressure within the aorta and give to the circulation the necessary rapidity of flow, and also the amount which flows back into the heart through the imperfectly acting valve. this it can do by contracting with greater force upon a larger amount of blood, the cavity becoming enlarged to receive this. not only may such damage to the valves be produced, but the muscular tissue of the heart may suffer from defective nutrition or from the effect of poisons, whether these are formed in the body as the effect of disease or introduced from without; or in consequence of disease in the lungs the flow of blood through them may be impeded, or disease elsewhere in the body, as in the kidneys may, by increasing the pressure of the blood within the arteries, throw more than the usual amount of work upon the heart. the power of the heart in meeting these conditions, however various they are and however variously they act, seems little short of marvellous, and it goes on throwing three and one-third ounces of blood seventy or eighty times a minute into a tube against nine feet of water pressure, working often perfectly under conditions which would be fatal to a machine. as long as this goes on the injury is said to be compensated for; the increased work which the heart is able to accomplish by the exercise of its reserve force and by becoming larger and stronger enables it to cope with the adverse conditions. with increased demand for work there is a gradual diminution of the reserve force. an individual may be able to carry easily forty pounds up a hill and by exerting all his force may carry eighty pounds, but if he habitually carries the eighty pounds, even though the muscles become stronger by exercise the load cannot be again doubled. the dilatation of the heart which is so important in compensation is fraught with danger, because any weakening of the muscle increases the dilatation, until a point is reached when, owing to the dilatation of the orifices between auricles and ventricles, the valves become incompetent to close them. when the heart is not able to accomplish its work, the effect of the condition becomes apparent by the accumulation of blood within the veins and a less active circulation. this affects the nutrition and the capacity for work of all the organs of the body, and the imperfect function of the organs may in a variety of ways make still greater demands upon an already overloaded heart. other conditions supervene. the increased pressure within the veins and capillaries due to the impossibility of the blood in the usual amount passing through or from the heart increases the amount of fluid in the tissues. there is always an interchange between the blood within the vessels and the fluid outside of them; the passage of fluid from the vessels is facilitated by the increased pressure within them, just as pressure upon a filtering fluid increases the rapidity of filtration, and the increase of pressure within veins and capillaries impedes passage of tissue fluid into them. the fluid accumulates within the tissues leading to dropsy, or the accumulation may take place in some of the cavities of the body. the diminished flow of blood through the lungs prevents its proper oxygenation; this may also be interfered with by the accumulation of fluid within the air spaces of the lungs. every additional burden thrown upon the heart increases the evil. in women the additional burden of pregnancy may suffice to overcome a compensation which has been perfect, and the same may result from an acute attack of disease. age, diminishing as it does the capacity for work in all organs, diminishes the compensation capacity of the heart, and a heart which at the age of forty acts perfectly may break down at the age of fifty. compensation may be gained in other ways, as by reducing the demand made upon the heart by changing the mode of life, by leading an inactive rather than an active life, by avoiding excitement or any condition which entails work of the heart. social conditions are of great importance; it makes a great difference whether the unfortunate possessor of such a heart be a stevedore whose capital lies in the strength of his muscles, or a more fortunately placed member of society for whom the stevedore works and whose occupation or lack of occupation does not interfere with the adjustment of his external relations to the condition of his heart. disease of the nervous system does not differ from disease elsewhere. the system is complex in structure and in function. it consists in nerves which are composed of very fine fibrils distributed in all parts of the body and serve the purpose of conduction, and a central body composed of the brain and spinal cord which is largely cellular in character; it receives impressions by means of the nerves and sends out impulses which produce or affect action in all parts. by means of the organs of special sense, the brain receives impressions from the outer world which it transforms into the concepts of consciousness. many of the impressions which the central nervous system receives from nerves other than those of special sense and even many of the impressions from these and the impulses which it sends out do not affect consciousness. the memory faculty is seated in the brain and all parts of the brain are closely connected by means of small nerve fibres. the nervous system plays an important part in the internal regulation and coordination of all parts of the body, and it is by means of this that the general adjustment of man with his environment is effected. malformations of the brain, except very gross conditions which are incompatible with extra-uterine existence, are not very common. at birth those parts of the brain which are the seat of memory and what are understood as the higher faculties are very imperfectly developed. variations in structure are extremely common, there are differences in different individuals in the nerves and in the number, size, form and arrangement of the nerve cells, and so complex is the structure that considerable variation can exist without detection. the tissue of the central nervous system has a considerable degree of resistance to the action of bacteria, but is, however, very susceptible to injury by means of poisons. serious injury or destruction of tissue of the brain and spinal cord is never regenerated or repaired, but adjustment to such conditions may be effected by reciprocity of function, other cells taking up the functions of those which were destroyed. certain parts of the brain are associated with definite functions; thus, there are areas which influence or control speech and motion of parts as the arm or leg, and there are large areas known as the silent areas whose function we do not know. all activity of the central nervous system, however expressed, is due to cell activity and is associated with consumption of cell material which is renewed in periods of repose and sleep. fig. 13 shows a nerve cell of a sparrow at the end of a day's activity and the same after the repose of a night. diseases of the nervous system have a special interest in that they so often interfere with man in his relations with his fellows. in diseases of other organs the disturbances set up concern the individual only. thus, others need not be disturbed save by the demands made on their sympathies by an individual with a cold in the head or a cancer of the stomach. disease of the nervous system is another affair, instead of those reactions and expressions of activity to which we are accustomed and to which society is adjusted, the reactions and activities are unusual and the individual in consequence does not fit into the social state and is said to be anti-social. there are all possible grades of this, from mere unpleasantness in the social relations with such an individual, to states in which he is dangerous to society and must be isolated from it. insanity is an extreme case. there is no disease signified in the expression, but it is merely a legal term to designate those individuals whose actions are opposed to the social state and who are not responsible for them. in insanity there is falsity in impressions, in conceptions, in judgment, a defective power of will and an uncontrollable violence of emotion. the individual is prevented from thinking the thoughts or feeling the feelings and doing the duties of the social body in the community in which he lives. the insane are out of harmony with their social environment, but not necessarily in opposition to it. there is no very sharp line between insanity and criminality. the criminal is in direct antagonism to the laws of social life. an insane person may cause the same injury to society as a criminal, but his actions are not voluntary, whereas the criminal is one who can control his actions, but does not. mentally degenerated persons, however, can be both insane and criminal. whatever the state of society, this reprobates the actions of one opposed to it; in a society in which it were usual to appropriate the possessions of others or to devour unpleasant or useless relatives, virtue and lack of appetite would be reprobated as unsocial. the symptoms of insanity or the manner in which the defective action of the brain expresses itself and the various underlying pathological changes vary, and by combining these it has been possible to subdivide insanity into a number of distinct forms. there are both intrinsic and extrinsic causes of insanity. the intrinsic are the structural differences in the brain as compared with the normal or usual, whether these are due to imperfection in development or to defective heredity or to the injury of disease; the extrinsic causes are those which come from without and bring the intrinsic into activity. syphilis is a frequent cause of insanity, and probably the only cause of the condition known as general paralysis of the insane, acting by means of the injury which it produces in the cortex of the brain. the abuse of alcohol is another fertile cause, but the changes produced in this are not so obvious as in the case of syphilis. tumors of the brain are not infrequently a cause, and the same is true of infections, even those not located in the brain. how susceptible the brain is to the effects of the toxines of the infectious diseases is shown in the frequency of delirium in these diseases. there is an interesting relation between this and alcoholism. alcohol abuse may produce injury, but not sufficient to manifest itself under ordinary conditions; when, however, the action of toxic substance is superadded to the effect of the alcohol the delirium of fever is more marked. probably of greater importance than the acquired pathological conditions of the brain in producing insanity is a congenital condition in which the nervous system is defective. the most fertile cause of insanity lies in the inheritance; by this it must not be understood that insane parents produce insane offsprings, but that conditions inherited from immediate or remote ancestors appear in a diminished resistance of the nervous system which is sooner or later expressed as insanity. given such a defective nervous system, extrinsic conditions which would have no effect on another individual or would be felt in different ways may produce insanity. in these cases occupation plays a great role. the excitement and privations of war especially in the tropics and the ennui of camps leads to insanity in soldiers; occupations such as that of the baker in which there is loss of sleep and the mental strain of students can all act in the same way. a woman who gives no sign of nervous defect may become insane under the strain of pregnancy. although insanity is determined by the social relations of man, that part of the social organization which is termed _society_, and which has been developed by the idle as a diverting game, is a fertile source of nervous disease and even of insanity, affecting particularly females. the strenuosity of the life, the nervous excitement alternating with ennui, the lack and improper times of sleep, the lack of rest and particularly of restful occupation, the not infrequent use of alcohol in injurious amounts, are all factors calculated to make a defect operative. the so-called "coming out" of young girls is an important element in the game, and their headlong plunge into such a life at a period under any conditions full of danger to the nervous system is especially to be reprobated. if we consider the influence of the game in other respects as conducing to lack of moral sense, to alcoholic abuse (for without the seeming stimulation, but which is really the blunting of impressions which alcohol brings, the game would not be possible), to discontent, to mental enfeeblement, it is all bad. curiously enough the game is one which in all periods has been played by the idle, but its evil influence is greater now than before when it was the game of royalty chiefly, because there are now more people living from the work of others. the unusual mental action of the insane not infrequently expresses itself by suicide. the analysis of three hundred deaths from suicide showed pathological changes in the brain in forty-three per cent, and when we think that mental disturbances are very often without recognizable anatomical changes after death, the percentage is very large. in another analysis of one hundred and twenty-four suicides forty-four of these were mentally affected to various degrees. five of the men and seven women were epileptics, in ten of the families there was hysteria, twenty-four of the men and four of the women were chronic alcoholics. it is extremely difficult at the present time to say whether insanity is increasing. statistics in all lands giving the numbers committed to insane hospitals show on their face a great increase, but so many factors enter into these statistics that their value is uncertain. there is now an ever-increasing provision for the care of the insane. owing to the recognition of insanity as a part of nervous disease and its separation from criminality there is no longer the same attempt to conceal it as was formerly the case, and hospitals for the insane are no longer associated with ideas of bedlam. it is generally believed that modern conditions in the hurry and excitement of life, and the extreme social differences, the greater urban life, the greater extension of factory life, all tend to an increase in insanity, but there is no absolute proof that this is true. we know very little about insanity in the middle ages, but the conditions then were not conducive to a quiet life. there prevailed then as now excess and want, luxury and poverty, enjoyment and deprivations, balls and dinner parties and other features of the social game. there were factions in the cities, public executions, not infrequent sieges, scenes of horror, epidemics, famines, and all these combined with religious superstition and the often unjust and cruel laws should have been factors for insanity. there were actual epidemics of insanity affecting masses of the population, as shown in the children's crusade, the jewish massacres and the dancing mania in the rhine provinces. where civilization seems to be the highest, statistics show the most insane, but this most probably depends upon better recognition of the condition and better provision for asylum care. the so-called functional diseases have a close relation with diseases of the nervous system, for they chiefly concern the reactions of nerve tissue. disease expressing itself in disturbance of function only, does not seem to fit in with the conceptions of disease which have been expressed, nor can we imagine a disturbance of function which does not depend upon a change of material. living matter does not differ intrinsically from any other sort of matter; like other matter its reactions depend upon its composition structure[1] and the character of the action exerted upon it. by functional disease there is expressed merely that no anatomical or chemical change is discoverable in the material which gives the unusual reaction. the further our researches into the nature of disease extend, particularly the researches into the physiology and chemistry of disease, the smaller is the area of functional disease. in functional disease there may be either vague discomfort or actual pain under conditions when usually such would not be experienced, and on examination no condition is found which in the vast majority of cases would alone give rise to that impression on the nervous system which is interpreted as pain. in the production of the sensations of disease there can be change at any place along the line, in the sense organs, in the conducting paths or in the central organ. thus there may be false visual impressions which may be due to changes in the retina or in the optic nerve or in the brain matter to which the nerve is distributed. it is perfectly possible that substances of an unusual character or an excess or deficiency of usual substances in the fluids around brain cells may so change them that such unusual reactions appear. there may be, of course, very marked individual susceptibility, which may be congenital or acquired. the perception of every stimulus involves activity of the nerve cells, and it is possible that the constant repetition of stimuli of an ordinary character may produce sufficient change to give rise to unusual reactions, and this particularly when there is lack of the restoration which repose and sleep bring. we know into what a condition one's nervous system may be thrown by the incessant noise attending the erection of a building in the vicinity of one's house or the pounding of a plumber working within the house, this being accentuated in the latter case by the thought of impending financial disaster. even the confused and disagreeable sound due to the clatter of high-pitched women's voices at teas and receptions may, when frequently repeated, be productive of changes in the nerve cells sufficiently marked to give rise to the unusual reactions which are evidence of disease. in the condition known as neurasthenia, which is often taken as a type of a functional disease, the basal and intrinsic cause is activity of the nervous system with the using up of material which is not compensated for by the renewal which comes in repose and sleep. neurasthenia is one of the common conditions of our civilization, found among children and adults, the poor and rich, the idle and the factory worker; it is rife in the scholastic professions and among those who earn their living by brain work. it seems to be more common in the upper classes and particularly in the women, but this is because these are more subject to medical care and the condition is more in evidence. there are all sorts of symptoms attached to the condition, for the unusual mental action can be variously expressed. the cerebral form has been thus described by a well-known medical writer: "one of the most characteristic features of cerebral neurasthenia is a weary brain. the sensation is familiar enough to any fagged man, especially if he fall short of sleep. impressions seem to go half into one's head and there sink into a woolly bed and die. voices sound far off, the lines of a book run into one another and the meaning of them passes unperceived. doors bang and windows rattle as they never did before; if a shoestring breaks, an imprecation is upon the lips. business matters are in a conspiracy to go wrong. letters are left unopened partly from want of will, partly from a senseless dread lest they contain bad news. at night the patient tosses on his bed possessed by all the cares which blacken with darkness. headache is common, loss of memory is distressing, and in severe cases it is wider and deeper than mere inattention can explain. there is often the torture of acute hearing, or an inability to suppress attention; the hater of clocks and crowing cocks is a neurasthenic." the disease is especially common in the women players of the social game, and its unhappy victims too often seek relief from the nervous irritability which is a common early symptom in still greater nervous excitement. it is a sad commentary on our civilization that one of the means of treatment for these persons which has been found efficacious is to supply them with some restful household occupation such as knitting or plain sewing, and there are institutions which combine refuge from social activities, often called duties, with simple occupation. footnote: [1] by structure as used in this wide sense, there must be understood not merely the anatomical structure, which is revealed by the dissecting knife and microscope, but molecular structure, or the manner in which elements are arranged to form the molecule, as well. chapter xii the rapid development of medicine in the last fifty years.--the influence of darwin.--preventive medicine.--the dissemination of medical knowledge.--the development of conditions in recent years which act as factors of disease.--factory life.--urban life.--the increase of communication between peoples.--the introduction of plant parasites.--the increase in asylum life.--infant mortality.--wealth and poverty as factors in disease. certain conditions have arisen in the past fifty years which have profoundly affected the thoughts, the beliefs and the activities of man. within this period what is generally known as darwinism, including under this evolution, has developed. unlike theories which came from philosophical speculation only, the theory of evolution was one which could be subjected to observation and experiment. it freed man's mind from dogmas, it stimulated the imagination, it enlarged the territory in which it seemed possible to extend knowledge by the methods of science, and has resulted in an enormous increase of knowledge. this has been more striking in medical science than elsewhere, and in this of more far-reaching influence. evolution coincided with another important development. history shows that all great periods of civilization have at their back sources of energy. in the civilizations of the past such sources of energy have come from the enslavement of conquered peoples or from commerce, or more direct forms of robbery, which have enabled a favored class to appropriate for its purposes the results of the work of others. while these sources have not been absent in the development of our civilization, the great source of energy has come from the rapid, and usually wasteful and reckless, utilization of the stored energy of the earth. the almost incredible advance in medical and other forms of scientific knowledge and the utilization of this knowledge is largely due to the greater forces which we have become possessed of. disease plays such a large part in the life of man and is so closely related to all of his activities that the changes in this period must have exerted an influence on disease. we have already seen that within the period we have obtained knowledge of the causes of disease and the conditions under which these causes became operative. the mystery which formerly enveloped disease is gone; disease is recognized as due to conditions which for the most part are within the control of man, and like gravity and chemical attraction it follows the operation of definite laws. there has been developed within the period what is known as preventive medicine, which aims rather at prevention than cure, and the resources of prevention are capable of much greater extension. have there been new conditions developed within the period, or an increase of existing conditions which can be regarded as disease factors and which counterbalance the results which have come from the knowledge of prevention and cure? there has been an increase of certain factors of immense importance in the extension of disease. these are: 1. the increase in industrialism, involving as this does an increase in factory life. in many ways this is a factor in disease. (_a_) by favoring the extension of infection, particularly in such diseases as tuberculosis. (_b_) the life indoors, and frequently with the combination of insufficient air and space, produces a condition of malnutrition and deficient general resistance. (_c_) the family life is interfered with by the mothers, whose primary duty is the care of home and children, working in factories, and the too frequent conversion of the house into a factory. (_d_) the influence of factory life is towards a loss of moral stamina rendering more easy of operation the conditions of alcoholism and general immorality. how great has been this increase in industrialism, fostered as it has been by conditions both natural and artificially created by unwise legislation, is shown in the figures from the last census. the number of factory operatives increased forty per cent between 1899 and 1909 and the total population of the country in the period between 1900 and 1910 increased twenty per cent. it is probable that the future will see an extension rather than a diminution of mass labor. 2. the increase in urban life is as conspicuous as the increase in industrialism. in 1880, twenty-nine and five-tenths per cent of the population was urban and seventy and five-tenths per cent was rural; in 1910, forty-six and three-tenths per cent was urban and fifty-three and seven-tenths was rural, the increase being most marked in cities of over five hundred thousand inhabitants. of the total increase in population between 1900 and 1910, seven-tenths per cent was in the cities and three-tenths per cent in the country. city life in itself is not necessarily unhealthy and there are many advantages associated with it. the conditions which have chiefly fostered it are the immigration of people who are accustomed to community life, the increase in factory life and the increased number of people of wealth who seek the advantages which the city gives them. the city has always been the favored playground for the social game. the unhealthy conditions of city life are due to the crowding, the more uncertain means of livelihood, the greater influence of vice and alcoholism. prostitution and the sexual diseases are almost the prerogatives of the cities. 3. all means of transportation have increased and communication between peoples has become more extended and more rapid. in the past isolation was one of the safeguards of the people against disease. with the increase and greater rapidity of communication there is a tendency not only to loss of individuality in nations as expressed in dress, customs, traditions and beliefs, but many diseases are no longer so strictly local as formerly--pellagra, for example. only those diseases which are transmitted by insects which have a strictly local habitat remain endemic, although the region of endemic prevalence may become greatly extended, as is seen in the distribution of sleeping sickness. diseases of plants and of animals have become disseminated. any plants desirable for economic use or for beauty of foliage and flower become generally distributed, their parasites are removed from the regions where harmonious parasitic inter-relations have been established, and in new regions the parasites may not find the former restrictions to their growth. there have been many examples of this, such as the ravages of the brown-tail and gypsy moths which were introduced into new england and of the san jose scale which was introduced into california. there have been many other examples of the almost incredible power of multiplication of an animal or plant when taken into a new environment, removed from conditions which held it in check, as the introduction of the mongoose into jamaica, the rabbit into australia, the thistle into new south wales and the water-plant chara into england. it is very difficult to say, but it seems as though there is an increasing unevenness in the distribution of wealth, an increase in the number of persons who live at the expense of the laboring class. mass labor, effective though it be, makes it easier to divert the proceeds of labor from the laborers. the evidence of this is seen in the increase in number and the prosperity of those pursuits which purvey to luxury, as the automobile industry and the florists' trade and the greatly increased scope and activity of the social game. on the other hand, there is an increase in the number of people who are to a greater or less extent dependent upon extraneous aid, evinced among other ways by the increase in the asylum populations. both these conditions, wealth and poverty, are important disease factors. tuberculosis is now a disease of the proletariat chiefly. the measures both of prevention and cure can be and are carried out by the well-to-do, but the disease must remain where there are the conditions of the slums. of all the conditions favoring infant mortality poverty comes first. in erfurt, a small city of germany, of one thousand infants born in each of the different classes, there died of the illegitimate children three hundren and fifty-two; of those of the laboring class, three hundred and five; of those in the medium station (official class largely), one hundred and seventy-three; of those in higher station, eighty-nine. the same relation of infant mortality to poverty becomes apparent when estimated in other ways. in berlin, with an average infant mortality of one hundred and ninety-six per thousand, the deaths in the best districts of the city were fifty-two and in the poorer quarters four hundred and twenty. the effect of poverty is seen particularly in the bottle-fed infants; with natural nursing the child of poverty has almost as good a chance as the child of wealth. from reasons which are almost self-evident, the mortality in illegitimate infants is almost double that of the legitimate. the greater infant mortality in poverty is due to the more numerous children preventing individual care, the separation of the mother from the nursing child in consequence of the demand made upon her earning capacity, and the decline in breast nursing. wealth is on the whole more advantageous from the narrow point of view of disease than is poverty, but if we regard its influence on the race its advantages are not so evident. nothing can be worse for a race than that it should die out, and wealthy families have never reproduced themselves. conditions always tending to destruction are a necessary part of the environment of poverty; wealth voluntarily creates these conditions, and chiefly by the pernicious influence of its amusements on the young. a new and in many respects a nobler conception of medicine has been developed. formerly medical practice was almost exclusively a personal service to the sick individual, and measures looking toward the general relief of disease and its prevention received scanty consideration. the idea of a wider service to the city, to the state, to the nation, to humanity rather than the personal service to the individual, is becoming dominant in medicine. this is seen in the establishment of laboratories by boards of health in cities and states in which knowledge obtained by exact investigations can be made of direct service to the people; in the medical inspection of schools and factories; in promulgating laws directed against conditions which affect health, in the extension of hospitals, and in divers other ways. the idea of public service and of returning to the people in an effective way some of the results of their labor also underlies the large donations which have been given for the creation of special laboratories and institutes in which, through research, greater knowledge of disease may be obtained and made available. the researches which have been made on the nutrition of man and the nutritive value of different foods are of great importance, and this knowledge has not yet begun to be applied as it should be. there seems to be a balance maintained between the restriction of disease by prevention and the increased influence of social conditions which are in themselves factors of disease. preventive medicine seems to have made possible, by restricting their harmful influence, the increase in industrialism, in urban life, and in the intercommunications of peoples. the most important aid in the future to the influence of preventive medicine must be the education of the people so that the conditions of disease, the intrinsic and the extrinsic causes and the manner in which these act, shall all become a part of general knowledge, and the sympathy of the people with health legislation and their active assistance in carrying out measures of prevention may be obtained. the effect of social conditions on disease must become more generally recognized. glossary atrophy--a condition of imperfect nutrition producing diminution in size and loss of function of parts. bertillon--a french anthropologist who devised a system of measurements of the human body for purposes of identification. blood-plasma--the fluid of the blood. cell--the unit of living matter. living things may be unicellular or composed of a multitude of cells which are interdependent. the general mass of material forming the cell is termed cytoplasm. in this there is a differentiated area termed nucleus which governs the multiplication of cells. in the nucleus is a material termed chromatin which bears the factors of heredity. chemotropism--the influence of chemical substances in directing the movement of organisms. exudate--the material which passes from the blood into an injured part and causes the swelling. fibrin--the gelatinous material formed in the blood when it clots. hæmoglobin--a substance which gives the red color to the blood; by means of its ready combination with the oxygen of the air in the lungs this necessary element is carried to all parts of the body. inflammation--literally a "burning"; the changes which take place in a part after injury. lymph--the fluid which is contained in the lymphatic vessels--nodes. circumscribed masses of cells connected with the lymphatic vessels. osmosis--the process of diffusion between fluids of different molecular pressures. spore formation--a mode of reproduction in lower forms of life by which resistant bodies, _spores_, are formed. these have many analogies with the seed of higher plants. symbiosis--a mutual adaptation between parasite and host. transudation--the normal interchange of fluid between the blood and the tissue fluids. the material interchanged is the transudate. tropism--the influence of forces which direct the movement of cells. ultra-microscope--a form of microscope which by means of oblique illumination renders visible objects so small as to be invisible with the ordinary microscope. virus--a substance either living or formed by living things which may cause disease. index amoeba, 13 anthrax, 109 antitoxin, 154 bacteria, 116 adaptation in, 123 ærobic, 122 anærobic, 122 artificial cultivation of, 119 distribution in nature, 121 growth and reproduction, 118 mode of action in disease, 144 size, 117 spore formation, 118 substances affecting growth of, 123 toxin production by, 144 variations in, 123 blood, 35 circulation of, 33, 80 vessels, 32 body, 22 defenses of, 146 organs of, 28 reserve force of, 50 surfaces of, 22 brain, 31 cerebro-spinal meningitis, 188 chemotropism, 93 cretinism, 37 darwinism, 240 death, 57 decomposition after, 51 rigor after, 60 signs of, 59 disease, 1 action of poisons, 44 acute and chronic, 219 industrialism as factor in, 243 lesions of, 46 superstitions concerning, 10 urban life as factor in, 244 wealth and poverty as factors in, 246 ductless glands, 37 embryo, 77 epilepsy, 209 eugenics, 215 foetus, 32 infection of, 200 foot and mouth disease, 129 glands, 22 growth, 62 heart, 33, 221 disease of, 223 heliotropism, 93 heredity, 197 influence of alcohol, 206 of insanity, 209 variations and imitations, 204 hookworm disease, 179 immunity, 148 theories of, 149 natural, 150 infection, 135 from external surface, 136 from genito-urinary surface, 137 from lungs, 138 from mouth, 138 from stomach and intestines, 139 from wounds, 141 in children, 195 in wild animals, 191 latent, 166 mixed, 160 racial susceptibility to, 191 resistance to, 143 by air, 170 by insects, 171 infectious diseases, 97 carriers of, 185 comparison with fermentation, 108 epidemics of, 98 endemic, epidemic and sporadic forms, 188 modes of transmission, 161 inflammation, 80 acute and chronic, 95 injury, 54-74 insanity, 231 causes of, 232 question of increase, 235 lesion, 17 leucocytes, 36 migration of, 92 living matter, 10 malaria, 175 rôle of mosquito in transmitting, 178 malformations, 211 heredity of, 215 maternal impressions, 212 nervous system, 228 disease of, 230 effect of social life on, 233 neurasthenia, 238 old age, 51 atrophy in, 51 blood vessels in, 54 causes of death in, 56 in animals and plants, 55 mental activity in, 53 osmosis, 91 opsonius, 153 ovum, 201 fertilization of, 198 infection of, 199 phagocytosis, 86 plague, 182 transmission by animals, 183 plasmodium malariae, 175 preventive medicine, 242 protozoa, 124 distribution in nature, 125 mode of growth, 125 sexual differentiation, 125 spore formation, 125 polyomyelitis, 190 repair, 46 conditions influencing, 47 scar, 49 skin, 21 sleeping sickness, 173 smallpox, 187 spontaneous generation, 106 sunburn, 83 syphilis, 193 tetanus, 142 thymus, 52 thyroid, 37 tonsils, 52 toxins, 144 tropisms, 93 trypanosomes, 172 tuberculosis, 163 infection by sputum, 169 modes of extension, 163 tumors, 64 benign and malignant, 69 cells of, 66 color, size and shape, 65 growth of, 65 importance of, 77 origin of, 66 question of increase, 69 theories of cause, 71 treatment of, 77 typhoid fever, 170 ultra-microscopic organisms, 128 virus, 128 yellow fever, 178 google books (the university of california) transcriber's notes: 1. page scan source: https://books.google.com/books?id=u3spaqaaiaaj (the university of california) the seafarers by the same author a bitter heritage. fortune's my foe. the scourge of god. across the salt seas. the clash of arms. denounced. in the day of adversity. the hispaniola plate. the desert ship. a gentleman adventurer. the silent shore. his own enemy. the seafarers by john bloundelle-burton author of 'the clash of arms' 'fortune's my foe,' 'across the salt seas' london c. arthur pearson limited henrietta street w.c. 1900 to all old friends and comrades who have been, or are still seafarers either in the royal navy or other branches of the sea service i inscribe this book contents chap. 1.

'here is my journey's end' chapter i 'sweeter than blue-eyed violets or the damask rose' that bella waldron should have felt sad, and her night's rest have been disturbed in consequence, was, in the circumstances, most natural. for one cannot suppose that any young girl leaves her home, her mother, and her country without much grief and perturbation; without tears and sorrow and heavy sighs, as well as tremendous fears that she may never return to, nor see, them again. and such is what bella was about to do when this particular night should have come to an end: she was about to traverse not one ocean, but two; to pass from a life that, if not luxurious, was at least comfortable, to another which, if more brilliant, would undoubtedly be strange, and, consequently, not easily to be adopted at first. in fact, to go from one side of the world to the other. yet, all the same, it was singular that, between her intervals of weeping and sobbing, and when she had at last cried herself to sleep, she should have been tormented with such frightful dreams as those which came to her. dreams of horrors that in their weirdness became almost ludicrous, or would have been ludicrous to those who, knowing of them, did not happen to be experiencing them. thus, the idea of a crocodile regarding one with a glittering eye from its ambush in the sand, seems for some reason, in our waking moments, to conjure up a comical sense of terror--perhaps because of the 'glittering eye'; yet there was nothing comical about it to the mind of bella as she awoke with a shriek from her sleep after the vision of the creature had had momentary existence in the cells of her brain. and, even when she was thoroughly awakened and knew that she had only been suffering from a bad dream, she still shuddered at the recollection, and muttered, 'it appeared as if it was creeping towards me to seize me with its horrid jaws! oh, it was dreadful!' then she slept again--only, however, to dream of other things. of a desolate shore at first, with, upon it, a misty creature waving its hands mournfully above its head, those hands being enveloped in some gauzy material, so that the figure appeared more like a skirt-dancer than aught else; then, of two lions fighting savagely; and then of a vast black cave with an opening as high as st. paul's and as wide as a railway terminus is long, against which, armed with a spear and protected with a buckler, she seemed to stand trembling. trembling, too, because she could not see one yard into the deep and profound darkness before her, yet into which, as she peered furtively and with horror, she appeared to perceive things--forms half-animal and half-human--crawling, revolving, creeping about. then, again, she awoke with a start. but by now the room was light with the gray, mournful glimmer of the approaching dawn; so light that she could see her wicker-basket trunks in their american-cloth wrappers standing by the wall, with the lids open against it; soon, too, she heard the sparrows twittering outside, as well as other congenial suburban sounds, such as the newspaper boys shrieking hideously to one another, and the milkman uttering piercing yells; and--though it was her last day in england--she was glad to spring out of bed and know herself once more a unit in the actual world instead of a wanderer in a world of dreams. 'i wish,' the girl muttered to herself, standing by the window and drawing up the blind half-way, whereby she was enabled to see that the gray dawn of a may morning gave promise of a warm, fine day later on, 'that, if i were to have such bad dreams at all, i might have been spared them on the very day of my departure for the other side of the globe. i am not superstitious, yet, yet--well!--i shall think of this dream, i know, for many a day to come.' then she slipped on her dressing-gown, thrust her pretty little white feet into some warm, felt bath-slippers, and, opening her door quietly, because it was still early and she did not wish to awaken those in the house who might be asleep, she went across the passage to her mother's room. yet, ere she did so, let us regard this young girl, whose story and adventures we are now to follow--this girl whose dreams of leering crocodiles and dark, mystic caves, with hideous creatures gyrating in them, will, as we shall see, be far outnumbered and outshone by the actual realities that she will experience in her passage across the world. for it had been resolved on by fate, or providence, or destiny, or whatever one may term that power which controls our earthly existence, that to bella waldron were to come experiences, strange, horrible, and fantastic, such as the last decade of our expiring century rarely assaults men with, and women hardly ever. standing there in the now clear light of the morning, her long dressing-gown enshrouding her tall, shapely, and _svelte_ figure, and with her masses of hair hanging dishevelled--hair a warm brown with golden gleams in it, such as has the ripening corn--an observer would decide at once that she was beautiful. beautiful, also, by the gift of clear, hazel-gray eyes--eyes that were pure and innocent in their glance; beautiful as well by her softly-rounded face, her rich red lips--the upper one divinely short--and also by her colouring. if, too, one applies to her the lines of that old poet dead and gone two hundred years ago, the words describing gloriana:- more fair than the red morning's dawn, sweeter than pearly dews that scent the lawn, than blue-eyed violets, or the damask rose when in her hottest fragrancy she glows, bella waldron may be considered as depicted. 'mother,' she said, going in now to the room where the poor lady whom she addressed had herself passed a sad and tearful night, bemoaning the fact that soon--in a few hours--indeed now--because the fateful day had come--her child was to be torn from her. 'oh, mother! it is to-day--to-day! oh, my darling! how can i part from you?' and then, folding her mother in her arms while she sat on the bedside, the two women wept together. 'yet,' said mrs. waldron, to whom advancing years brought the power of philosophic resignation, if not the thorough strength to overcome that which rendered her unhappy, 'yet, bella, my dearest, it is so much for you. such a position, such a future! oh, think of it! a position you could scarcely ever have hoped to obtain. and the love, my child, the love! think how gilbert loves you and you love him. for you do love him, bella. of all men, he is the one for you.' 'with my whole heart and soul i love him!' her daughter answered. 'mother, if i had never met him i do not believe i could have ever loved any other man. ah, i am glad juliet called romeo the god of her idolatry! it has taught me how to think of gilbert.' 'and the position, bella. the position--think of that! in our circumstances, even though you come of a good stock and are descended from ladies and gentlemen on both sides from far-off years, you could never have hoped to make such a match.' 'the position is nothing to me, mother. i love gilbert fondly. i long to be his wife. why should i think of the position?' 'every woman must think of it, child. when you are as old--and worn--as i am, you--you will teach your own children to think of it. it is everything to be the wife of a gentleman, better still the wife of a man of rank. everything! short of being the wife of a distinguished man, a man whose name is on everybody's tongue, there is no other position so good. and, even then, that distinguished man may not be a gentleman as well. that would be dreadful. yet your husband will be both. think, bella! he is sure to become a nobleman, and he may become the most renowned admiral in the navy.' 'you dear old mother! but i love gilbert because he is gilbert. otherwise, neither the nobility which is certain, nor the renown which is prospective, would take me across the world to him. do you think i would go to bombay to marry the heir to a title or a possible admiral if i did not love him?' 'heaven forbid!' mrs. waldron replied, as she sat up in her bed and smoothed her hair. 'heaven forbid! yet,' she murmured, perhaps a little weakly for a lady who had just delivered herself of such admirable sentiments, 'yet i do honestly think, darling, that the love you bear each other--yes! above all, the love--and the position--i must think of the position, bella!--and the certainty of a brilliant future for you, reconcile me a little to parting with you. some day, when you are a mother, you will understand me.' 'i understand you now, darling. yet, yet--ah!' and now she sobbed on her mother's shoulder--'yet, to think of our being parted for so long--for three years! gilbert must remain on the station for that length of time.' now it is certain that mrs. waldron was sobbing too, yet, because there was something of the spartan mother, something, too, of cornelia, mother of the gracchi, about her, she calmed her sobs. for she, too, had been ruthlessly torn by an all-conquering lover, who would take no denial, from her parents, arms. yet that lover had had no such proud future to offer her as the gilbert of whom they spoke had to offer his beloved arabella; for her there had been nothing to flavour her existence except the glorious spice tasted by us all--of loving and being loved. and now--now that she was what she called old--which was not the case, since she was still short of her forty-fifth year--now she knew--and, knowing, said--that love accompanied by brilliant prospects and an assured future was the most satisfactory of all loves. 'your father,' mrs. waldron said, 'remained on his station, the pacific, for seven years, and we were separated all that time. he there, i here, in london. and in lodgings, bella--oh those lodgings and that cooking!--you remember, darling? you must remember the lodgings and the cooking, child though you were. and he was not a future peer, though he did once think he might become an admiral.' 'forgive me, mother,' bella said, kissing her mother again and again. 'i will not repine any more. i ought not to do so, i know. for is not my gilbert the handsomest, bravest sailor that ever wore the queen's uniform? and it won't be so long after all. only--only--i do wish there wasn't that awful journey. oh if there were only a bridge!' and for the first time she smiled. 'or a railway,' she added. 'i am sure, bella,' her mother said, forgetting how she would feel that evening when her child was gone, and neither the bright voice nor brisk footsteps would be heard any more in the house, 'i am sure you cannot complain of the manner in which you are going out. the vessel may not be as comfortable as they say the great liners are, but at least your uncle is the captain, and it is his own ship. and that cabin he showed us yesterday, when we went down to gravesend, is far better than anything you could get in any liner, even the best. i had one once, when i went out to join your father at halifax, in which there was nowhere but the pockets of my clothes to keep things in, while the other lady above me could open the scuttle as she lay in her berth. and your cabin is as big as a dining-room, with a sofa----' 'you dear, darling mother!' bella exclaimed. 'you are an angel to comfort me thus, when i know all the time that your heart is as sad as mine. oh if we had not to part!' and again the two women hugged and kissed each other. chapter ii stephen charke a year before this momentous day when arabella waldron was to set sail for india in her uncle's full-rigged ship, the emperor of the moon, there had come to her that supreme joy which is the most sweet experience of a young girl's life. the man she was madly in love with had asked her to be his wife, and, so far as it was possible to forecast the future, it seemed that before them both there stretched a long vista of happy years to be spent together, or as many years together as a sailor and his wife can pass during the greater part of their lives. yet, who can foretell the future--even so much as what to-morrow may bring forth? to-day we are here, to-morrow we are gone. a bicycle accident has done for us, or we have caught a fever or pneumonia, and we are no more. how, then, was bella to know that events would so shape themselves that, ere she had been a year engaged to her future husband, she would be on board the _emperor of the moon_, bound for the other side of the world, and that during her passage in the good old ship, named after an ancient play--a representation of which one of the late owners had witnessed in his boyhood--she would encounter such calamities and perils? but let us not anticipate. rather, instead, let us describe who bella was, and how she came to love and to be loved, to be wooed and won. our english girl! the girl fairly tall, and full to the brim with health; full, too, of a liking for all exercise which befits the dawning woman--for boating, riding, walking, cycling: not ashamed to acknowledge that she likes a good dance and that she has a good appetite for a ball supper; one who is, withal, not a fool! where in all the world can you find anything better than that--better than the honest girls who have been our mothers, are our wives, and, please god, are what our daughters will be? such a one was bella waldron. she could take a scull--and pull it, too--as well as any of her sisters whom you shall meet 'twixt richmond and windsor; she could cycle thirty miles a day, eat a good dinner afterwards, and then go to a dance in the evening; and she thought nothing of walking from west kensington to piccadilly or regent street, with a glance at the kensington high street shops on her way!--especially when the winter remnant sales were on and advertised daily in glowing terms. of riding she knew little, because horse-exercise is a more or less expensive luxury, and also because an income of £600 a year does not allow much in the way of luxuries, even when there are only two people in the family and two servants (with an odd boy) kept. and that sum represented mrs. waldron's income. bella's mother had been a miss pooley, who had married the late commander waldron (retired with the brevet rank of captain), and to this lady there remained only one near relative, besides bella, at the time this veracious narrative opens. now, this gentleman merits a slight description, not only because he plays a considerable part in those adventures and tribulations which, later on, befell the girl, but also because he occupied a position almost unique and, consequently, conspicuous in these modern days. fifty--nay, thirty years ago, there would not have been anything peculiar in the career he followed; but now, with the twentieth century close upon us, that career was almost a singular one. captain pooley was a sea captain--a mercantile sea captain--owning two ships of his own, and always in command of one of them. that which he now commanded was the very _emperor of the moon_ of which you have already heard, and of which, if you follow this narrative, you will hear a great deal more; the other was a brig called _sophy_, which will not figure at all in these pages. now captain pooley, as he was called by everybody, though, of course, he had no right whatever to that distinctive appellation, had as a young man possessed an extraordinary love for the sea, so intense a love, indeed, that he, not being able to obtain a nomination for the royal navy, had induced his father to apprentice him to the merchant service. later in life--one must be brief in these preliminary descriptions!--he had, after obtaining all his certificates, purchased one after the other, with some little money he had inherited, shares in first the one ship and then the second, and eventually, by aid of savings and successful trading, had become the entire owner of both. for the rest--to be again brief--he was a gentleman in manner and in feelings, while in his person he was a handsome, burly man, with the brightest of blue eyes, a vast shock of remarkably white hair above a good-looking, ruddy, tan-brown face; and was also the possessor of a smile which appeared more often than not upon his good-humoured countenance, and helped to make him welcome wherever he went, both at home and abroad. he was, it should be added, a married man, but childless, and it was not unusual for him to occasionally take his wife on the voyages he made for the purpose of transporting the goods which he sold in distant parts of the world, as well as for the purpose of purchasing other goods for sale in england. otherwise, mrs. pooley remained at home in a pretty little villa at blackheath, of which he owned a long lease. it was a year before the great joy of bella's life came to her that the 'captain,' returned from a voyage to calcutta, and, as was always the case with him, he went to west kensington to visit his sister and niece, accompanied by his wife. these visits were invariably paid, and also invariably returned by mrs. and miss waldron, and were generally productive of a great deal of pleasure on either side. captain pooley--as we will continue to term him--was a kind-hearted, open-handed man, who loved his own kith and kin and cherished an old-fashioned notion--still in existence, heaven be praised, amongst many members of various classes of society--that people should do as much as lay in their power to make their relatives happy. wherefore, on this night, he said, as he took the head of mrs. waldron's table--which she always insisted on his doing whenever he stayed with her--and while he carved a pair of most excellent fowls: 'so i think we shall have a good time of it all round, mary,'--mary being mrs. waldron's name. 'to-night we will go to the lyceum, and to-morrow--well, to-morrow--we'll see. then, next week, southsea. southsea's the place for us. great doings there next week, bell. the visit of the foreign fleet now there will beat everything that has gone before.' 'but the expense, george!' exclaimed his sister. 'the expense will be terrible. i saw in the paper that everything would be at famine price.' the captain pooh-poohed this remark, however, saying that an old friend of his, who had retired from the royal navy and was now living at that lively watering-place, knew of a little furnished house which could be obtained reasonably if taken for the following week, as well as for the principal one. and he clinched the remark by saying, 'and i have told him to secure it.' there was therefore nothing further to be said on that score, bella alone remarking that she had the best old uncle and aunt that ever lived. 'there will be,' he continued, putting a slice of the breast upon her plate, probably as a reward for her observation, 'plenty to amuse bella. there is a garden-party at whale island; another given by the general; and a ball given by the navy at the town hall. that's the place for you, bella. if you don't find a husband there--and you a sailor's daughter, too--well!----' but these remarks were hushed by his wife, who told him not to tease the child, and by the beautiful rose blush which promptly rushed to his niece's cheeks. yet, all the same, bella thought it very likely that she would have a good time of it. they were playing _madame sans-gêne_ at the lyceum that evening--though pooley rather wished it had been something by shakespeare--and on the road to the theatre in the cab he told them that he had taken another stall, to which he had invited a young friend of his whom he had run against in town a day or two ago. 'and a very good fellow, too,' he said, 'besides being a first-rate sailor. and he has had a pretty hard struggle of it, owing to his being cursed with a cross-grained old father, who seemed to imagine his son was only brought into the world that he might sit upon him in every way. all the same, though, stephen charke got to windward of him somehow.' 'whoever is he, uncle?' bella asked, interested in this story of the unknown person who was to make a fifth of their party; while her mother addressed a similar question to mrs. pooley. 'he is,' said the captain, 'a young man of about thirty, who once went to sea with me in the _sophy_; the son of an old retired officer, who was years ago in a west indian regiment. after petting and spoiling the boy, and--as stephen charke himself told me--almost treating him with deference because he happened to have been born his son, he afterwards endeavoured to exert a good deal of authority over him, which led to disagreeables. he wanted the lad to go in for the army, and stephen wanted to go to sea.' 'and got his way, apparently,' said bella. 'he did,' her uncle replied, 'by absolutely running away to sea--just like a hero in a boy's book.' 'how lovely!' the girl exclaimed. 'ha! humph!' said pooley, rather doubtfully, he being a man who entirely disapproved of disobedience in any shape or form from a subordinate. 'anyhow, his experiences weren't lovely at first. they don't take runaways in the best ships, you know. however, he stuck to it--he had burnt his boats as far as regards his father--and--well!--he holds a master's certificate now, and he's both a good sailor and a good fellow. he is in the naval reserve, too, and has had a year in a battleship.' 'and his father?' mrs. waldron asked. 'are they reconciled?' 'the old man is dead, and charke has three or four thousand or so, which makes him more or less independent. he's a queer fish in one way, and picks and chooses a good deal as to what kind of ship he will serve in. for instance, he won't go in a passenger steamer, because, he says, the mates are either treated with good-natured tolerance or snubbed by the travellers, and he aims at being an owner. however, as i said before, he's a good fellow.' by this time the cab had forced its way along the strand amidst hundreds of similar vehicles, many of which were disgorging their fares at the various other theatres, and at last, after receiving a gracious permission to pass from those autocratic masters of the public--the police stationed at the foot of wellington street--wrenched itself round and pulled up in its turn beneath the portico of the theatre. 'there's charke!' said pooley, while, as he spoke, a rather tall, good-looking man of dark complexion, who was irreproachably attired in evening dress, came up to them and was duly introduced. to bella, whose knowledge of the world--outside the quiet, refined circle in which she had moved--was small, this man came more as a surprise than anything else. she knew nothing of the sea, although she was the daughter of an officer who had been in the royal navy, and her idea of what a 'mate' was like was probably derived from those she had seen on the jersey or boulogne packet-boats, when her mother and she had occasionally visited these and similar places in the out-of-town season. yet stephen charke (she supposed because he was a gentleman's son, and also because of that year in a battleship as an officer of the r.n.r.) was not at all what she had expected. his quiet, well-bred tones as he addressed her--with, in their deep, ocean-acquired strength, that subtle inflexion which marks the difference between the gentleman and the man who is simply not bad-mannered--took her entirely by surprise; while the courteous manner in which he spoke, accompanied by something that proclaimed indubitably his acquaintance, not only with the world, but its best customs, helped to contribute to that surprise. so that, as they proceeded towards their stalls, she found herself reflecting on what a small acquaintance she had with things in general outside her rather limited circle of vision. chapter iii 'let those love now who never loved before' the 'captain' led the way into the five stalls he had booked, followed, of course, by the elder ladies, and, as stephen charke naturally went last, it fell out that bella and he sat by each other. and between the acts, the intervals of which were quite long enough for sustained conversation to take place, the girl had time to find her interest in him, as well as her surprise, considerably increased. she had perused in her time a few novels dealing with the sea, and, in these, the mates of ships of whom she had read had more or less served to confirm her opinion, already slightly formed from real life. but, when charke began to talk to her about the actual source from which the play they were witnessing was drawn, she acknowledged to herself that, somehow, she must have conceived a wrong impression of those seafarers. certainly he, she thought, could not be one of the creatures who cursed and abused the men if they objected to their food, and threatened next to put them in irons; nor did she remember that such individuals had ever been depicted in sea stories as knowing much about the revolution in france and the vulgar amusements of napoleon. then, during the next interval, he approached the subject of the forthcoming festivities at portsmouth, to which bella's uncle had told him he was going to take his relatives, and from that he glided off into the statement that he himself would be there. 'i am going down next monday,' he said, 'to see one or two of my old mess-mates of the _bacchus_--in which i served for a year in the channel squadron--and i fancy i shall be in at most of the functions. have you ever been to a naval ball?' bella told him she never had been to one, her mother's intimacy with the service having entirely ceased since captain waldron's death, and he then proceeded to give her an account of what these delightful functions were like. indeed, so vividly did he portray them that bella almost wished they were going on that very night to take part in one. when the play was over, she--who acknowledged to herself that which probably no power on earth would have induced her to acknowledge so soon to any one else, namely, that stephen charke was an agreeable, if not a fascinating, companion--in company with the others prepared to return to west kensington, bidding goodbye to him in the vestibule of the theatre. 'where are you staying?' mrs. waldron asked him, as they stood on the steps waiting for their cab to make its appearance in turn. 'and are you in london for any time?' charke mentioned the name of a west end caravanserai, at which he had a room, as his abode for the next day or so, and by doing so he administered one more shock of surprise to the girl standing hooded and muffled by his side. for, again, in her ignorance, or perhaps owing to her reading of nautical novels, she had always thought of the officers of merchant vessels as living somewhere in the purlieus of ratcliffe highway when ashore, and rarely penetrating farther west than the city itself. it seemed, however, that either she had formed a totally erroneous impression of such people, or that the above sources of information must be wrong if all were really like mr. charke. but then, suddenly, there occurred to her mind the fact that her uncle had said this young officer was in possession of some few thousand pounds of his own--and this, probably, would explain why he was living in a comfortable manner when he was ashore. 'i am at home to my friends every other friday,' mrs. waldron said, as now the cab had got to the portico, and a man was bawling out 'mrs. pooley's carriage' at the top of his voice--which announcement, nevertheless, served the purpose required--'and the day after to-morrow happens to be one of those fridays. if you care to call--though i know gentlemen despise such things--we shall be glad to see you.' 'i do not despise them,' charke answered, 'and i shall be delighted to come.' then he bade them all good-night, saw the cab off, and strolled down to his hotel. in his innermost heart charke did despise such things as 'at homes,' or 'tea fights,' as he termed them contemptuously to himself, yet, in common with a great many other men, he was willing enough to go to them when there was any attraction strong enough to draw him. and he told himself that there was an attraction at mrs. waldron's such as he had never been subjected to before. 'what a lovely girl,' he thought to himself; 'what eyes and hair--and a nice girl, too! now i begin to understand why other men curse the sea, and say they would rather earn their living on shore driving busses than following our calling. and, also, why they nail up photographs in their cabins and watch every chance of getting mails off from the shore. i suppose i should have understood it earlier if i had ever met a girl like this.' he did call on the following friday, after having passed the intervening two days in wandering about london; in going to a race meeting one day and a cricket match at the oval the next; in trying a dinner at one foreign restaurant on the wednesday, and another at a second foreign restaurant on thursday; but all the time he felt restless and unsettled, and wished that four o'clock on friday was at hand. 'this won't do,' he said to himself, before the cricket match on thursday was half over, and while he sat baking in the sun that streamed down on to the oval--which disturbed him not at all, and had no power to make him any browner--'this won't do. i must go to sea at once. by the time i have seen that girl again i shall be head over ears in love with her. and the interest on £4000 in india stock--by jove! it isn't quite £4000 since i've been loafing about on shore!--and a chief officer's pay won't keep a wife. not such a wife as she would be, anyway.' he did not know it--or, perhaps, he did know it and would not acknowledge it to himself--but he was very nearly head over ears in love with bella waldron already. and he had only seen her once--been by her side at a theatre for three hours--with three intervals of ten minutes in which to talk to her! yet the girl's beauty, her gentle innocence, and above all, that trusting confidence with which she seemed to look out upon all that was passing before her, and to regard the world as what it appeared to be and to take it at its own valuation, had captured him. still, he should have known--he must have known--that when a man who has never thought much of the women he has met heretofore, and has generally forgotten what their features were like by the next day, takes to lying awake for hours dreaming at last of one woman with whom he has by chance come into contact, he is as nearly in love with her as it is possible for him to be. so, at least, those report who have been in love, and so it has been told to the writer of this narrative! he made his way to montmorency road, west kensington, exactly at four o'clock, and while he sat in the pretty drawing-room talking to mrs. waldron, who was alone at present--the appearance of bella being promised by her mother in a few moments--he found himself wondering what the girl did with her life here. he had seen a bicycle in the passage as he was shown upstairs, so he supposed she rode that; while there were some photographs of rather good-looking men standing about on the semi-grand and on the plush-covered mantelshelf--which made him feel horribly annoyed, until mrs. waldron, seeing his glance fixed on them, informed him that they were mostly cousins who were out of the country, and that one or two of them happened to have succumbed to various climatic disorders abroad, for which catastrophes he did not seem to feel as sorry as he supposed he ought to do. then bella came in, looking radiantly beautiful in a summer dress (a description of which masculine ignorance renders impossible), and stephen charke was happy for ten minutes. for they all talked of the impending _fêtes_ at portsmouth in honour of the foreign fleet, and charke found himself in an elysium when bella promised him--without the slightest self-consciousness or false shame--that she would undoubtedly have some dances reserved for him. yet, soon, other callers came in, and stephen charke found himself deprived of the pleasure of further conversation with bella. an elderly dowager claimed her attention, and a middle-aged lady--of, as he considered, menacing aspect--regaled him with the evil doings of her domestic servants, a subject of about as much interest to this wanderer of the seas as that of embroidery or tatting would have been. an irish doctor of divinity also disturbed his meditations on bella's beauty by telling funny stories, the point of which the divine had forgotten until he refreshed his memory by reference to a little note-book in which he had them all written down, while a young militia subaltern who had failed for the army--and seemed rather proud of it!--irritated him beyond endurance. yet, even through this fatuous individual, there came something that was welcome to him, since he saw bella regarding the youth with a look of scarcely veiled contempt, and he longed to tell the idiot that the only failure for which women have no pity in this world is that of the intellect. 'goodbye,' he said to bella, who accompanied him to the head of the stairs, after he had made his adieux to her mother. 'goodbye. next week--portsmouth--and--my dances.' 'i shall not forget,' she said. after which he wandered off by devious and intricate ways (which reminded him of some of the narrow passages he knew of between the islands in the china seas) and so arrived at the district railway. and all the time he was telling himself that he was a fool--an absolute fool. 'i have fallen in love with a girl i have only seen twice,' he meditated, as the train ran through the sulphurous regions underground, and he endeavoured to protect his lungs by smoking cigarette after cigarette; 'a girl who is not, and never can be, anything to me. she will make a good match some day; she must make a good match--girls of her position and looks always do; and, a year or two hence, i shall luff into some unearthly harbour abroad, and run against pooley, who will tell me that she has done so.' yet, all the same, he took comfort from remembering that he had not seen anybody at mrs. waldron's 'afternoon' who was likely to be the individual to carry her off. but, in spite of this soothing reflection, he braced himself to a stern resolution: he determined that, as already in his life he had triumphed over other things, so he would triumph now. he would triumph over this swift-flowering and still growing love; conquer it by absence from the object which inspired it; trample it down till there was nothing left of life in it. 'i have no money to keep a wife,' he thought, as he walked up from charing cross station to his hotel; 'certainly no money to keep such a wife as she would be. and, even if i had, it is not likely that she would marry me; "a common mate," as i have heard ourselves called. portsmouth shall end it,' he concluded. 'i'll have one good week there, and then to sea again on a long cruise. that ought to do it! i'll go down to the docks to-morrow and see what's open.' wherefore, full of this determinate resolution to drive from out of him the frenzy which had taken possession of his heart and mind, he went to the hotel and read in his bedroom for an hour or so, during all of which time bella waldron's face was looking out at him from the pages of the _navy and army illustrated_, and was always before him until he went forth to try still another foreign restaurant. yet she was there too, and her pure, innocent eyes were gazing at him across the imitation flowers and the red candle-shades in the middle of the table; and so, also, they were in the stalls of the empire, until he fell asleep in his seat. nor was she absent from his mind during the long hours of the night. chapter iv portsmouth _en fête_ the lunch at whale island was over, and there was a slight breathing-space ere the garden-party, which followed it, began. meanwhile, from southsea pier, from down by the pontoon at the foot of the old hard, and over from gosport, picket-boats, steam pinnaces, and launches--all belonging to her majesty's ships lying out at spithead--were coming fast, as well as shore boats and numerous other craft that blackened the waters. and they bore in them a gaily-dressed crowd of men and women, the ladies being adorned in all those beauteous garments which they know so well how to assume on such an occasion; while, among the gentlemen, frock-coats, tall hats, and white waistcoats, as well as full dress, or 'no. 1' uniform, were the order of the day. for all these ship's-boats, after putting off from the battleships and cruisers to which they belonged, had, by order of the vice-admiral commanding the channel squadron, called at the above-named places to fetch off the visitors to the whale island festivities. stephen charke, in the uniform of the r.n.r., came in the picket-boat of the _bacchus_, wherein he had been lunching with the wardroom officers, and as she went alongside of southsea pier, and afterwards at the old town pier, he had eagerly scanned the ladies who were waiting to be taken off. he was not, however, particularly disappointed or cast down at not seeing the one girl he was looking out for at either of them, since, in the continual departure of similar boats, and the running backwards and forwards of these craft between whale island and the landing-stages, it was, of course, hardly to be supposed that she would happen upon the particular boat in which he was. he saw her, however, directly he, with his companions, had made their way to the lawn on which the wife of the port-admiral was receiving her guests, and--in so seeing her--he recognised instantly that he was not going to enjoy his afternoon as much as he had hoped to do. 'who's that?' he asked of the staff-commander of the _bacchus_, with whom he happened to be walking at the moment. 'i mean that flag-lieutenant talking to the young lady in the white dress?' 'that?' replied his companion, regarding the young officer indicated. 'oh, that's gilbert bampfyld, flag-lieutenant to the rear-admiral. he's a good chap; i'll introduce you later. a lucky fellow, too. he's heir to his uncle, lord d'abernon. he's all right,' he concluded inconsequently. 'i know the young lady,' stephen said. 'i've been at sea with her uncle.' 'good-looking,' said the staff-commander, who was a single man. 'fine girl, too. i hope she's coming to the ball.' 'she is,' charke replied, and then stood observing her companion from the little group of which they now formed part. certainly the young officer was 'all right,' if good looks and a manly figure can entitle any one to that qualification. he was undoubtedly handsome, with the manliness which women are stated (by authorities on such matters) to admire: his bright eyes and good complexion, as well as his clear-cut, regular features, leaving little else to desire. he was also fairly tall, while, if anything were required to set off his appearance, it was furnished by his full-dress and his flag-lieutenant's aiguillettes. he was talking now in an animated way, as charke could see easily enough from where he stood by the refreshment tent; and it was not possible for him to doubt that he was making himself very interesting to bella. for a moment, stephen stood hesitating as to whether he should go up and present himself to the girl who had never been out of his thoughts since he said 'goodbye' to her in west kensington; then, while he still debated the matter in his mind, bella saw him and smiled and nodded pleasantly, while she looked--as he thought--as though she expected he should come up to her. which of course decided him. there was no affectation in the manner wherewith bella greeted him; in truth, she was glad to see him and, honestly, as she did everything else, she said so. 'i have been looking for you for the last half-hour,' she remarked, as he reached her side, 'and wondering if you were coming or not'; after which she introduced stephen charke and gilbert bampfyld to each other. then, some other officers coming up at this moment, more introductions took place, while bampfyld said that he must move off. 'i have escaped from my admiral for a few moments,' he said, while he added with a laugh: 'i am not quite sure, however, that he is not congratulating himself on having escaped from me. i hope, miss waldron,' he added, 'that you have an invitation for the ball?' 'yes,' bella said; and she smiled at lieutenant bampfyld's request that he might not be forgotten on that occasion, though she did not say positively whether that calamity would occur or not. then, when he had moved on to join the distinguished officer to whom it was his duty to be attached almost as tightly as a limpet to a rock, she said to charke, 'come, now, and see mamma. she is in the shade behind the tent, and she has found an old friend of father's.' but it was so evident that mrs. waldron was thoroughly enjoying herself with that old friend, who was a retired post-captain (she was, indeed, at the moment of their arrival engaged in reminiscences of the north american and west indian stations), that they strolled away together, and, finding soon another shady seat, sat down and passed an agreeable hour or so. wherefore, as you may thus see, stephen charke did spend a happy afternoon, notwithstanding that first apparition of the flag-lieutenant in converse with the girl who was now never out of his thoughts. indeed, it would have been to him a perfect afternoon, had he not more than once seen bampfyld (who again appeared to have escaped from his admiral!) roaming about the place with a somewhat disconsolate, as well as penetrating, look upon his face; which look charke construed into meaning that the other was seeking for the girl of whom he himself had now obtained temporary possession. however, even so, he did not think it necessary to call bella's attention to the fact. but we must not tarry over these soft summer beguilements to which the old naval capital and all in her had given themselves up. there lie other matters before us--matters which, when they afterwards occurred, caused three people now partaking of these enjoyments to, perhaps, cast back their memories,--memories that were not untinged by regret. suffice it, therefore, that we hurry on, and passing over another garden-party which took place at the military commandant's, and an 'at home' given on board the foreign visitors, flagship, as well as entertainments at which only the male sex were present, we come to the naval ball at the town hall. that was a great night, a night on which, if one may judge by subsequent events, many loving hearts were made happy; on which, too, some saw the dawn of the first promise of future happiness--and one man, at least, was made unhappy. it was a great night! a night no more forgotten by three people in the days that followed it than was the garden-party which preceded it by a day or so. the first lord of the admiralty led off the quadrille with the wife of the commander-in-chief, while the prince who was in command of the foreign fleet danced with the first lord's wife; there being in that set, round which the other guests formed a vast circle, the most prominent individuals then present in portsmouth. and bella, standing close by with her hand upon the arm of stephen charke, while they waited for the first dance in which all the guests could participate, felt that, at last, she knew what a ball was. 'it isn't quite like a state ball,' whispered lieutenant bampfyld to them as he passed by with his admiral, he being qualified to give such information in consequence of his duties as flag-lieutenant having often given him the opportunity of attending those great functions, 'but it is much prettier.' then he disappeared for a time. 'it could scarcely be prettier than it is,' bella said to charke. 'how has the room been made so beautiful?' 'the men of the _vernon_ have done it all,' her companion answered; 'they are good at that sort of thing.' as, indeed, they seemed to be, judging by the effect they had produced. trophies of arms, flags, devices, life-buoys white as snow, with the names of vessels belonging both to the visitors and ourselves painted in gold upon them, decorated the vast room; while, from the dockyard, had been unearthed old armour and weapons, such as, in these present days, are forgotten. also the colour lent by various uniforms, naval, military, and marine, as well as by flowers and the bouquets carried by ladies, added to the brilliant scene--while the sombre black of civilians helped to give a contrast to the bright hues. for civilians were not forgotten: admiralty officials, private residents, special correspondents--with a wary eye on their watches, so that they might be able to rush over to the post-office with their last messages for the great london and provincial papers--were all there. 'come,' said stephen charke, as the band of the royal marines struck up the first waltz, 'come, miss waldron; it is our turn now.' and for ten minutes he realised what happiness meant. that he would have to resign her for the greater part of the evening, he knew very well--her programme was already full!--his name appearing three times on it, and lieutenant bampfyld's also three times--yet, later, he did so none the less willingly for that knowledge. how could he? he loved the girl with his whole heart and soul--madly! 'i shall love her always, until i die,' he muttered to himself as he stood by, seeking no other partner and watching her dancing now with the flag-lieutenant. then, next, he saw her dancing with the flag-lieutenant of the other admiral--though that did not seem to him to be so disturbing a matter. 'till i die!' he repeated again; and then once more called himself a fool. his second dance with her arrived, and once more he was in his seventh heaven; for the moment he was again supremely happy. 'i hope i may have the pleasure of taking you in to supper,' he almost whispered in her ear as they paused for a moment for breath, and it seemed as if the light of his enjoyment--for that evening at least--had been suddenly extinguished when she, raising those sweet, clear eyes to his, exclaimed: 'oh, i am so sorry! but i have promised lieutenant bampfyld that he shall do so.' for the remainder of the ball charke did not let a single dance pass by without taking part in it, and allowed his friends to introduce him right and left to any lady who happened to require a partner, though reserving, of course, the one for which he was engaged to bella at what would be almost the end of the evening. in fact, as his friend the staff-commander said, 'he let himself go pretty considerably,' and he so far exemplified that gentleman's remark that he took in to supper one of the plainest of those middle-aged ladies who happened to be gracing the ball with their presence. yet this lady found nothing whatever to complain of to herself (to her friends she would have uttered no complaint of her cavalier, even though he had been as stupid as an owl and as dumb as a stone, she being a wary old campaigner), but, instead, thought him a charming companion. perhaps, too, she had good reason to do so, since, from the moment he conducted her across the temporarily constructed bridge which led from the town hall proper to the supper tent erected in a vacant plot of ground, his conversation was full of smart sayings and pleasant, though occasionally sub-acid, remarks on things in general. yet, naturally, it was impossible that she should know that the undoubtedly bright and piquant conversation with which he entertained her was partly produced by his bitterness at seeing gilbert bampfyld and bella enjoying themselves thoroughly at a table _à-deux_ close by where he and his partner were seated, and partly by his stoical determination to 'let things go.' and by, also, another determination at which he had arrived--namely, to go to sea again at the very first moment he could find a ship. chapter v 'so farewell, hope!' nine months had passed since the entertainment of the foreign fleet at portsmouth--months that had been pregnant with events concerning the three persons with whom this narrative deals; and bella sat now, at the end of a dull march afternoon, in the pretty drawing-room in west kensington. she sat there meditating deeply, since she happened to be alone at the moment, owing to mrs. waldron having gone out to pay several calls. of all who had been at those entertainments, of all in the party which, in the preceding june, had gathered together at portsmouth, the three ladies of the family, mrs. waldron, mrs. pooley, and bella, were alone in england; the three men--the three sailors--were all gone to different parts of the world. captain pooley had sailed with his vessel to australia; stephen charke had gone to china as first officer of a large vessel; and gilbert bampfyld, who, in consequence of the rear-admiral's retirement, no longer wore the aiguillettes of a flag-lieutenant, had been appointed to the _briseus_, on the east indian station. and bella, sitting now in her arm-chair in front of the drawing-room fire, with a letter lying open on her lap before her, was thinking of the writer of that letter, as well as of all that it contained. if one glances at it as it lies there before her, much may be gleaned of what has happened in those nine months; while perhaps, also, some idea, some light, may be gained of that which is to come. 'my darling,' it commenced (and possibly the writer, far away, may have hoped that, as he wrote those words, they would be kissed as often by the person to whom they were addressed as he fondly desired), 'my darling--your letter came to me to-day, and i must write back to you at once--this very instant--not only because i want to put all my thoughts on paper, but also because i can thus catch the p. and o. mail. how good! how good you are! while, also, i do not forget how good your mother is. i know i ought not--at least i suppose i ought not--to ask you to do such a thing as come out to me, and i can assure you i hesitated for weeks before daring to do so. yet, when i reflected that, if you could not bring yourself to come, as well as induce your mother to give her consent to your coming, we could not possibly be married for three years, i could not hesitate any longer. and now--now--oh, bella, my darling! i could dance for joy if my cabin was big enough to allow of such a thing--you are coming! you will come! how happy we shall be! i can think of nothing else--nothing. you don't know how i feel, and it's useless for me to try to tell you....' no more need be read of this letter, however, and, since the reader will shortly be informed of what led to it, nothing more need be said than that, after a good deal of explanation as to how the young lady to whom it was addressed was to make her plans for reaching bombay, it was signed 'gilbert bampfyld.' so that one sees now what had been the outcome of that week of delight at portsmouth during the last summer; one understands all that had been the result of those garden-parties and that ball. they--the festivities--were followed by a renewal of the acquaintanceship between mrs. waldron and her daughter and gilbert bampfyld, as, indeed, the latter had quite made up his mind should be the case, and as--since the truth must always be spoken--bella had hoped would happen. they were followed, that is to say, directly the naval man[oe]uvres were over, for which important function both divisions of the channel squadron were of course utilised, while not a week had elapsed from the time of the return of the ships to their stations before gilbert bampfyld presented himself in montmorency road. and that presentation of himself at this suburban retreat was, it is surely unnecessary to say, succeeded by many other things, all showing what was impending and what actually happened later on. gilbert bampfyld told bella that he loved her and wanted her for his wife, and--well, one can imagine the rest. what was there to stand between those loving hearts? what? nothing to impede their engagement, nothing that need have impeded their immediate marriage, except the fact that bella's maiden modesty could never have been brought to consent to a union so hurriedly entered into as would have been necessary, had she agreed to become gilbert's wife ere he set out for bombay to join the _briseus_, to which he was now appointed. one regrets, however, when describing such soft and glowing incidents as these, that space is so circumscribed (owing to the canvas having to be filled with larger events now looming near) as to leave no room for more minute description of this love idyl. it would have been pleasant to have dwelt upon bella's ecstatic joy at having been asked to be the wife of the one man--the first man--whose love she had ever desired (ah, that is it--to be the first man or the first girl who has ever touched the heart of him or her we worship); only it must not be--the reader's own imagination shall be asked to fill the missing description. let those, therefore, who remember the earliest whispered word of love they ever spoke or had spoken to them; who recall still the first kiss they ever gave or took; and those who can remember, also, all the joy that came to them when first they loved and knew themselves beloved, fill the hiatus. that will suffice. 'we shall be so happy, dearest,' gilbert said, when all preliminaries had been arranged in so far as their engagement was concerned, and when he did not know at the time that he was about to be sent on foreign service, but hoped that he would either be allowed to remain in the channel squadron or be transferred to the training squadron, or, at worst, appointed to the mediterranean. 'we shall be so happy, darling. i hoped from the first to win you--though--though sometimes i feared there might be some one else.' 'there could never have been any one else. never, after i had once met you,' she murmured. 'oh, gilbert!' and then she, too, said she was so happy. yet a moment later she whispered: 'but, somehow, it seems too good to be true. all has come so easily in the way that i--well, as we--desired, that sometimes i think there may be--that something may arise to--to----' 'what--prevent our marriage? nothing can do that. nothing could have done that--nothing!' 'suppose your uncle, lord d'abernon, had objected?' she said, remembering that she had heard how this nobleman was not always given to making things quite as easy and comfortable to those by whom he was surrounded as was considered desirable. 'suppose that had happened?' 'oh, he's all right,' gilbert replied. 'he expected his opinion to be asked and his consent obtained, and all that sort of thing, but, outside that, he's satisfied. and if he wasn't, it wouldn't have made any difference to me--after i had once seen you.' for which remark he was rewarded with one of those chaste salutes which bella had learnt by now to bestow without too much diffidence. as regards mrs. waldron--well, she was a mother, and it was not to be supposed that such a distinguished match as bella was about to make could be aught but satisfactory to her; while captain pooley, who had not yet departed with the _emperor of the moon_ for australia, told his niece that she was a lucky girl. he also informed gilbert that, as he was a childless man, bella would eventually fall heiress to anything he and his wife might leave behind them. matters looked, therefore, as though they would all go merry as the proverbial marriage bell. all, as the old romancists used to say, was very well. then fell the first blow--the one that was to separate those two fond hearts. gilbert was suddenly appointed to the _briseus_ and ordered to proceed to bombay to join her at once, and a fortnight later he was gone, and poor bella was left behind lamenting. she was sitting, lamenting still, before her fire on this march day, with this newly-arrived letter on her lap--in solemn truth, she had been lamenting his departure ever since it had taken place--when, suddenly, there broke in upon her ears the sound of a visitor's knock below. then, ere she could distinguish whose voice was addressing the servant who had answered the door, she heard a manly footstep on the stairs, and, a moment later, the maidservant announced: 'mr. charke.' mr. charke! the man whose memory had almost faded from her mind--as she had reproached herself for more than once, when it did happen to recur to her--the man whom she had learnt to like so much during all that happy time last year. now, as she gazed on him, and noticed how brown he was as he came forward--more deeply browned, indeed, than she had thought it possible for him, who was already so tanned and sunburnt, to be--and noticed, too, the strong, self-reliant look on his face, she reproached herself again. she acknowledged, also, that she had liked him so much that even her new-found happiness ought not to have driven all recollection of him entirely from her mind. then she greeted him warmly, saying all the pleasant little words of welcome that a woman whose heart goes in unison with her good breeding knows how to say; and made him welcome. yet, as she did so, she observed that he was graver, more sad, it seemed to her, than she had ever remarked before. 'you are not ill?' she asked, as this fact became more and more apparent to her. 'surely, you, a sailor, have not come back from the sea unwell? at least i hope not.' 'no,' he said, 'no. nor, i hope, do i seem so. do you know that, besides any desire to call and see you, i came for another purpose?' and now his eyes rested on her with so strange a light--so mournful, deep a light--that in a moment her woman's instinct told her what he meant as plainly as though his voice had done so. like a flash of lightning, that instinct revealed to her the fact that this man loved her; that, from the moment they had parted, months ago, she had never been absent from his mind. she knew it; she was certain she was right--she could not be deceived! then to herself she said: 'heaven help him--heaven prevent him from telling me so.' but aloud, her heart full of pity, she said: 'indeed,' and smiled bravely on him while she spoke. 'indeed, what was that purpose?' 'to congratulate you. to---'congratulate me!' 'yes. i met the _emperor of the moon_ at capetown. we were both homeward bound. and--and--your uncle told me the news. i offer my congratulations now.' yet, as he said the words, she saw that his face was turned a little aside so that she could not perceive his eyes. congratulations! well, they might be sincere in so far as that, because he loved her, he wished her well and desired that she should be happy, but--but--otherwise--no! it was not to be thought upon. as he said the words: 'i congratulate you,' he followed an old custom--one more foreign than english--and held out his hand, taking hers. and he kept it, too, fast in his own, while he said in the voice that his struggles with the elements had made so deep and sonorous: 'yes, i congratulate you. i must do that. to--to--see you happy--to know you are so, is all that i have--all--i hope for now. yet there is no treachery to him in what i say. heaven help me! i mean none--but--but--i--from the first--i have lo----' 'no, no,' she murmured, striving to withdraw her hand, yet not doing so angrily. 'no, no. don't say it, mr. charke. don't, pray don't.' and, now, neither could he see her eyes nor her averted face. 'don't say it. you do not desire to make me unhappy?' she murmured. 'never, as god hears me. but--i have said it. i had to say it. goodbye.' 'goodbye,' she said--and then, as he neared the door, she turned once and looked at him with eyes that were full of intense pity and compassion. chapter vi 'and bend the gallant mast, my boys' events are now drawing near to that night when bella was to have those distressing dreams which have been mentioned at the opening of this narrative; all was arranged for her departure to bombay. a little more, and she will be on her way to india and to wedlock. yet all had not been quite easy and smooth in the settlement of affairs. at first, mrs. waldron, good, loving mother though she was, and fully cognisant of the facts--namely, that bella loved lieutenant bampfyld madly and would be an unhappy woman if she did not become his wife long ere three years had passed, and that the match which her child was about to make was undoubtedly a brilliant one--refused to hear of such a thing as that she should go out to him. 'if you are worth having,' she said, when first the proposal was submitted to her, 'you are surely worth coming for.' and, since this was a truism, it was hardly to be gainsaid. yet, as we know by now, she had been won over by her daughter's pleadings and entreaties; by, too, the plain and undeniable fact that there was not the slightest possibility of lieutenant bampfyld being able to come home to marry her, or to return to england in any way--short of being invalided--until the _briseus_ herself returned. then, no sooner had this difficulty been surmounted than another reared its head before mother and daughter. how was she to go out to bombay alone and unprotected? a young married woman, who had to proceed to india to join her husband, might very well undertake such a journey, but not a young single woman such as bella was, while for chaperon or protectress there was no one forthcoming. at first, it is true, mrs. waldron had meditated accompanying bella herself (she being an old sailor, to whom long sea voyages were little more than railway journeys are to some more stay-at-home ladies); only, down in the depths of her nature, which was an extremely refined one, there was some voice whispering to her that it would be indelicate to thus bring her daughter out in pursuit of her affianced husband. it is true, however, that authorities on social etiquette who have since been consulted have averred that this was a false feeling which was in possession of mrs. waldron's mind; but be that as it may, it existed. then, too, she still regarded the matter of her child going to her future husband, instead of that husband coming to fetch her, as one of particular delicacy; one of such nicety as to permit of no elaboration; and she resolved that, come what might--even though she should have to purchase, or hire rather, the services of an elderly and austere travelling companion--she must not herself accompany bella. 'heaven knows what is to be done,' she said to her daughter, as they discussed the important point, 'but i suppose it will come to that'; the 'that' meaning the hired chaperon. then she sighed a little, remembering how the late captain waldron had encompassed thousands of miles in a voyage which he made from the antipodes to espouse her. yet, ere many days had passed, the clouds of obstruction were suddenly removed in a manner which seemed almost--as the fond mother stated--providential. captain pooley's ship had followed home, after a week or so of interval, that in which stephen charke had returned to england, and its arrival was soon succeeded by his own in montmorency road. 'going out to him to be married!' he exclaimed, after his sister--who happened to be alone at the time of his visit--had made him acquainted with what she had given her consent to some two or three months before, on gilbert's application backed up by bella's supplications, and which consent she had moaned over inwardly ever since she had so given it. 'going out to be married, eh? why, she must want a husband badly!' yet, because he knew well enough the customs of her majesty's service and the impossibility which prevailed in that service of an officer coming home to marry his bride, he did not repeat her words, 'if she is worth having, she is worth coming for.' 'so other people have thought, if they have not openly said so,' mrs. waldron replied. 'i am sure they must have thought so. yet,' she went on, with determination, 'i have agreed to it, and i cannot retract my word. it is given, and must be kept. no, it is not that which troubles me.' 'what, then?' 'why, the getting out. how is the child to go alone, in a great liner, with two or three hundred passengers, all the way to bombay? how?' she repeated. 'bombay, eh? bombay. oh, well, if that's her destination, she can go comfortably enough. there need be no trouble about that. only she will be more than double the time the p. and o., or any other line, would take to carry her.' 'what do you mean, george?' 'why,' he said, 'i happen to be taking the old _emperor_ to bombay next month with a general cargo--calling at the cape on the way. she can go with me, and welcome. there's a cabin fit for a duchess which she can have.' * * * * * * it was a cabin fit for a duchess, as bella and her mother acknowledged when, a fortnight later, they went down to gravesend to inspect the _emperor of the moon_, and after it had been decided in solemn family conclave that, by this ship, the former should make the voyage to india. and it was more than likely that the girl would make it under particularly pleasant circumstances, since this was one of those occasions on which mrs. pooley had decided to accompany her husband, she not having felt very well during the past winter. at present, the cabin was empty and denuded of everything, pooley having decided to have it refurnished; but when he told them how that furniture would be arranged in the great roomy place, which would have been dignified as a 'state-room' in one of the old clippers, bella said again, as she had said so often before, that 'he was the best old uncle in the world.' now the _emperor of the moon_ was a smart, though old-fashioned, full-rigged ship of about six hundred tons, her lines being perfect, while leaving her full of room inside. her saloon was a comfortable one, well furnished with plush-covered chairs and benches--the covering being quite new; a piano--also looking new--was lashed to the stem of the mizzen-mast, while there were swinging vases, in which, no doubt, fresh ferns and flowers would be placed later. on deck she was very clean and white, with much brass and everything neat and shipshape, while the seaman who should regard her bows and stern would at once acknowledge that she left little to desire, old as she was. for, in the days when she was laid, they built ships with a view to both sea qualities and comfort, and the _emperor of the moon_ lacked neither. her sleeping-cabins were bedrooms, her saloon was a dining-room as good as you would find in a fifty-pound-a-year suburban residence, and her masts would have done credit to one of her majesty's earlier ships. altogether, bella was pleased with everything, especially with her cabin, which was on the port side of the saloon, and she was, besides, pleasantly excited at the idea of so long a sailing voyage. 'i know,' she said to her uncle, 'that we shall have a delightful time of it, and for companionship i shall have you and auntie. that's enough.' 'you will have some one else, too,' pooley said, with a smile; 'you know i have two officers. come'--and again he smiled--'it is our "lay days,"' by which he meant that they were shipping their cargo. 'come, i will introduce them to you.' then he led the way up the companion to the deck. they met one of these officers, the second mate, a young man whom pooley introduced as mr. fagg, and then, while they were all talking together, bella heard a deep, low voice behind her say: 'how do you do, miss waldron?' a voice that caused her to start as she turned round to find herself face to face with stephen charke. 'you!' she exclaimed involuntarily. 'you! are you going on this voyage?' 'i am first officer,' he said. 'i wanted a berth, and captain pooley has given me one.' and amidst her uncle's joyous laughter and his remark that he knew this would be a pleasant surprise for bella, and while, too, mrs. waldron said that she was delighted to think he would be in the ship to look after her daughter, that daughter had time to think herself--to reflect. in her heart, she would far rather that charke had not been here; while she wondered, too, how he could have brought himself to accept his present position, knowing, as he must have known, that she was going in the ship. 'it is so vain, so useless,' she thought; 'and can only lead to discomfort. we shall both feel embarrassed all the way. oh, i wish he were not coming!' then, although she pitied him, and although she had always liked him, she resolved that, through the whole of the time they were together in the ship, she would see as little of stephen charke as possible. 'you do not object to my presence, i hope?' he said a moment later, as they both stood by the capstan alone--pooley and his wife and sister having moved off forward. 'i should be sorry to think that my being here was disagreeable to you. i have to earn my living, you know.' 'what right could i have to object, mr. charke?' 'perhaps you think i have behaved indiscreetly?' for a moment she let her eyes fall on him and rest upon his own; then she said: 'i will not give any opinion. you have to earn your living, as you say; while as for me--well, you know what i am going to india for.' 'yes,' he answered. 'i do know.' after which he added: 'do not be under any wrong impression. i shall not annoy you. i am the chief officer of this ship and you are a passenger. that is, i understand, how the voyage is to be made?' 'if you please,' bella replied very softly, and the tones of her voice might well have brought some comfort to him, if anything short of the possession of her love could have done so. a fortnight or three weeks later the pilot had left the _emperor of the moon_, the lee main braces were manned, the ship was lying over under her canvas, the wind was well astern. bella was on her way to india and her lover! let us pass over this parting between mother and child, the fond embraces, the tears and sobs which accompanied that parting following after the dawn when we first made the girl's acquaintance, and following, too, that night of unrest and disturbing dreams. no description of such partings is necessary; many of us, young and old, men and women, have had to make them; to part from the loved, gray-haired mother who has sobbed on our breast ere we went forth to find our livelihood, if not our fortune, in a strange world; many of us have had to let the child of our longings and our hopes and prayers go forth from us who have sheltered and nurtured it--from us who have perhaps prayed god night and day that, in his mercy, it might never leave our side. we go away ourselves because we must; also they go from us because they must; and there is nothing but the same hope left in all our hearts--the hope that we shall not be forgotten--that, as the years roll by, those we have left behind will keep a warm spot for us in their memory, or that those who have left us behind will sometimes turn their thoughts back longingly to us in our desolation. it has to be, and it has to be borne; alas, that parting is the penalty we all have to pay for having ever been permitted to be together. and, so, across the seas, the stout old _emperor of the moon_ went; buffeting with the channel, throwing aside the rough waves with her forefoot as though she despised them, sinking england and home behind her with every plunge she made. and at the moment that she was leaving the lizard far away astern of her, and was running well out into the atlantic, a telegram was delivered in montmorency road addressed to bella, which was opened by her mother. a telegram signed 'gilbert,' which ran: 'don't start. _briseus_ appointed to east coast africa, slaver catching.' a telegram that had come three days too late! a telegram that was re-forwarded to capetown, where it lay for forty-seven days awaiting the arrival of the _emperor of the moon_, and, then,--was forgotten! chapter vii 'an ocean waif' from the time the men had sheeted home the topsails as the _emperor of the moon_ got under way until now when, having left the cape of good hope behind her, she was travelling through the water at a very fair speed and with her head set due north, scarcely anything had occurred much worthy of note. soon--after the first two days had passed, during which time bella had lain flat in her berth in the large roomy cabin provided for her by her uncle, while his wife had administered to her odd glasses of champagne, little cups of rich, succulent soup, and such like delicacies--the girl was able to reach the deck. and, once there and under an awning stretched from the ensign staff to past the mizzen-mast, she would sit and meditate for hours on the forthcoming meeting with her lover which was drawing nearer and nearer with each plunge of the emperor's forefoot into the sapphire sea. sometimes, too, she would read aloud a novel to mrs. pooley, who, perhaps because she was good and motherly, and fat, would listen to nothing but the most romantic love-stories which the vivid brains of fashionable novelists could turn out; though, when alone, and reading for her own amusement, bella would pore over books of adventure in wild parts of the world, or devour some of the histories of marine voyages which her uncle possessed in his neat mahogany bookcases below. of stephen charke she saw, of course, a good deal, as it was natural she should do. you cannot be in a ship, however large or small, without seeing much of all on board; but when it comes to sitting down every twenty-four hours to what captain pooley called 'four square meals a day, with intervals between for refreshments,' you must not only be brought into constant touch with your companions, but also enter into much discourse with them. yet, as the girl told herself, charke was behaving well, extremely well; so that, gradually, she lost all sense of discomfort that would otherwise have arisen through being thrown continuously into his society, and, ere long, she would observe his approach without the slightest tremor of susceptibility. soon, too, she began to acknowledge to herself that stephen was a gentleman in his feelings, and that, no matter what his sentiments might be towards her--if they existed still and were unchanged from what they had once been--he at least knew how to exercise that control over them which a gentleman should be capable of. until now, he had never said one word to her that any other person might not have uttered who had found himself thrown into her society on board the _emperor of the moon_, nor had he unduly sought her presence or, being in it, endeavoured to remain there as long as it was possible. nothing of much note had occurred thus far on the voyage, it has been said; yet there had of course been some of those incidents without which no voyage of any distance is ever made. once through the bay, and, while they ran swiftly south, they had found themselves in a dense fog--a most unusual thing in such a latitude and at such a time of year; then, upon the top of that fog, there had sprung up a stiff breeze which gradually developed into a gale, so that, from clewing the main royal to furling the top-gallant sails of the mizzen and foremasts was but the action of a moment, as was the next work of taking in the main top-gallant sail. and thus, ere long, bella had her first experience of what a storm at sea was like, and, as she heard the live stock grunting and squealing forward; the ship's furniture more or less thundering about wherever it could get loose; the piano--on which, only the night before, she had played the accompaniment to her uncle's deep bass voice as he trolled out 'in cellar cool'--thumping heavily against the bulkhead to which it was usually lashed, and the cries of the sailors as they uttered words which might not, perhaps, be properly denominated as 'cries, alone, she began to wonder how her darling gilbert could ever have chosen such a calling. while, too, the streaming planks when, at last, she ventured on deck, the dull sepia clouds and the mournful look of the emperor herself, under reefed topsails, foresail, fore topmast staysail, main trysail and spanker, as she rolled and yawed about in the troughs and hollows of the sea, and took the water first over one bow and then over another--and then, for a change, over her stem--only increased that wonder. yet, lo! the next morning--for the sea is a great quick-change artist, volatile and variable as a flirt, though too often as tragic as medea herself--when bella looked out of her scuttle, against which the green water now slapped boisterously but not viciously--all was changed. a bright sun shone down from the blue heavens, the ship had still got a roll on her, though not an unpleasant one--and the girl felt hungry. which was as good a sign that the storm was over as could well be wished for. 'it has been a rough night,' stephen charke said, as he rose from his breakfast on her entrance to the saloon, helped her to her chair, and bade the steward bring coffee and hot rolls and bacon--all of which were already perfuming the air. 'your uncle is now on deck. we have been there all night.' 'i thought,' said bella, pouring out her coffee and smiling pleasantly, since now all fear had departed from her mind that charke would misconstrue any friendly marks of intimacy she might be disposed to graciously bestow on him, 'that i was at the end of my journey. indeed, that we all were; that it was brought to a sudden end; accomplished. that----' 'that,' said stephen, smiling too, sadly enough, yet enhancing wonderfully his dark, handsome looks by doing so, 'that perhaps mr. bampfyld might miss his bride!' for a moment bella's hazel eyes flashed at him, and he thought how wondrously beautiful they looked as they did so--then a serious expression came on her face. while, after pausing a moment, as though scarcely knowing what answer to make or whether she should make one at all, she said: 'yes. that he might miss his bride. my death, and that alone, could cause him to do so.' and as she spoke she looked stephen straight in the face, while feeling again--to her regret--that old sentiment of doubt of him which she had come to believe she had conquered and subdued. 'his death would cause the same result,' he answered, speaking slowly, hesitatingly, for in truth he felt as if he were treading on dangerous ground. and in a moment he found such was the case. 'mr. charke,' the girl said, very quietly now, 'i should be so much obliged to you if, during the remainder of our journey together, you will neither discuss my affairs nor those of my future husband, nor him. it will make the voyage pleasanter to me if you will do that.' as she spoke, the bell struck two, and, since the watches had been disorganised by the storm of the night, that sound meant that captain pooley would now come below for his breakfast, and his place above be taken by the mate. therefore, he turned towards the stairs, muttering: 'i beg your pardon, i am sure. pray forgive me. i will not offend again.' then he disappeared on to the deck. yet an hour later he stood by her side beneath the awning, and now he was directing her attention to something that, a mile off, was the object of attention from every one on board. the captain and his wife were both regarding it fixedly; so, too, were the men forward; the only persons not present being, of course, the watch below and the second mate, mr. fagg, who had now turned in. 'what do you make it out to be?' asked pooley of stephen, as they still gazed at it. 'it is not a baby nor a child; yet it is scarcely bigger than the first. can it be a dog?' 'no,' said charke authoritatively, as though his younger eyesight was not to be disputed; 'it is either a young tiger or a panther cub afloat on a water-cask. there has been a wreck during the night, i expect, and it has got adrift. perhaps,' he said, 'if we cruise around a bit we may find some human life to save.' 'how should it be aboard any ship?' asked the captain. 'who takes tigers or panthers for passengers?' 'plenty of people,' charke answered quietly. 'they are brought home to sell to the menageries and zoos. a cub like that is worth twenty pounds--worth looking after. guffies bring them home sometimes, sailors often. meanwhile,' he added, 'according to the set of the waves, that thing will be alongside us in a quarter of an hour. i'll bet a day's pay it strikes the ship betwixt the main and mizzen channels.' 'oh,' exclaimed mrs. pooley and bella together, 'do let us save it and get it on board! it will,' said the latter, 'be such a lovely plaything--and such a curiosity! fancy a girl from west kensington who has never had a plaything or pet more stupendous than a canary, a cat, or a fox-terrier, having a tiger. why,' she exclaimed, with a laugh which gave to her short upper lip an appearance of tantalising beauty, 'una will be outdone by me--a girl of the nineteenth century!' tantalising or not as that smile might be, it led to the salvation of the cub; for, with a swift look at the captain which was meant to ask for his assent, charke called to one of the sailors to get over into the channels and down on to the fourth futtock, he telling him with wonderful accuracy the exact spot where the water-cask would strike the stationary ship. five minutes later, that which he had calculated with such precision came to pass, the cask touched the vessel's side almost immediately beneath the man's feet, and, in another moment, the cub had been caught by its loose skin in the exact middle of its back and hauled up, squealing, spitting and scratching, on to the deck. 'the little beast!' exclaimed the mate, as he sucked the back of his hand where the creature had clawed him; 'the little beast! this is a pretty reward for our saving it from drowning!' and he administered a sound kick to the thing as it lay on the deck. so sound and rousing a one, indeed, that it gave a grunt of pain, and, with its claws--about as big, or bigger, than those of a good-sized cat--endeavoured to fasten on to his legs. while, from its yellow, scintillating eyes, it emitted a glance of such malignant ferocity as, had it been more fully grown, might have alarmed a braver man than he. 'oh, how cruel to kick that poor little half-drowned thing!' bella exclaimed reproachfully; 'it never meant to hurt you, only it was frightened. poor little thing!' she said again, and, even as she spoke, she knelt down on the deck and stroked the wet, striped ball that lay there. and it seemed as if her gentleness had some power to soothe whatever ferocious instincts--still dormant and undeveloped at present--were smouldering within it. for, instead of now using its paws as weapons with which to strike out and attack anything near it, it played with her as a kitten plays with a ball, tapping at her hand and trying to catch it, and pushing and kicking against her with its hind legs. 'you see,' she said, looking up at charke with a glance in which she could not disguise her dislike of his violence, 'you see, at present, at least, it does not try to harm those who treat it well.' 'yes,' he said, 'i see.' then he added, half-bitterly, half-morosely: 'no one doubts your powers of fascination, miss waldron.' chapter viii 'his name is--what?' the saving of this creature, which bella elected to call bengalee, because she said she was sure it came from bengal, and also because she had once sung a song having that name, was followed by no other events of any importance whatever. nor need their stay at the cape be dwelt upon, because it consisted simply of various visits which were paid in the outskirts by mr. and mrs. pooley, accompanied by bella; by the unloading of a considerable portion of the cargo of the _emperor of the moon_, and by the refilling of the hold with other goods saleable in india. and, now, they were once more on their way towards the equator, going due north instead of due south, as when they had last approached it, and with a cool southern breeze driving the emperor along under full sail. yet, so gentle was this breeze that, even if there had been any who were not sailors in the ship--as bella, as well as mrs. pooley, might now well be considered, after the length of voyage she had already gone through, added to a few extra days and nights of turbulence and storm--scarcely would they have felt any inconvenience from the motion. thus, therefore, with occasionally a dropping of the wind which reduced their speed a few knots, and, sometimes, with a total drop in it, so that they did not progress a knot an hour, while the ship swung slowly round and round the compass, they found themselves at the time which is about to be described in about latitude 45.10 s., and longitude 30.50 e., or, as near as may be, about 250 miles to the s.w. of mauritius. wherefore, since the _emperor of the moon_ has arrived thus far in the indian ocean there has now to be set down a series of strange events which befell her, of so remarkable and peculiar a nature that one wonders that those events have never been chronicled before. for, far different from the ordinary stress and disasters which overtake ships at sea were those which have to be described; far different from those which the recorders of maritime calamities are in the habit of chronicling either in romance or dry-as-dust descriptions of facts. all of which the writer now proceeds to relate, beginning with so strange a coincidence as, perhaps, none but those readers who, in their voyage through life, have recognised that truth is more strange than the wildest fiction, will be willing to allow within the bounds of likelihood. however, to make a beginning--since the coincidence is true--the _emperor of the moon_ was in those latitudes above described when, it being a bright hot morning with the sea already gleaming like molten brass, with the pitch between the planks already of the consistency of putty, and with the brasswork in such a state of heat that it was unsafe to touch it unless one wanted to leave the skin of his palms and fingers behind them, the look-out on the fo'c's'le head yelled: 'sail, right ahead!' now, since nothing of this kind, neither steamer nor sailing vessel, had been seen since they had northed out of the west-wind drift, and since, also, the liners were rarely found outside of the equatorial current, this cry was sufficient to fill every one on board with a considerable amount of interest and excitement. 'whereaway?' called out charke, who was on the poop at this moment, the captain, his wife, and bella being below at breakfast; and, ere the man could repeat that the sail was right ahead and about five miles off, all those others there had come on deck. 'how pretty it looks, shining in the sun!' the girl exclaimed, as she regarded it through a pair of marine glasses which her uncle had placed at her disposal; 'and how the sail glistens! it looks like a star.' 'humph!' said the captain, as he gazed through his binocular. 'like a star! true enough, so it does. and,' he said, addressing the two mates who were standing near him, 'we have seen such stars hereabouts before, eh? do you think,' he went on, addressing charke, lowering his voice a little, 'it is one of those?' 'don't know,' charke said, working his own glass a good deal. 'can't see how it can be; too far to the east. bussorah, muscat, ras-el-had, mohamrah, oman--that's their mark. what should they be doing here?' 'all the same,' exclaimed pooley, 'it's the rig, and the true shape, that of a jargonelle pear cut in half. i do believe that's what it is. they might have been blown out of their course, you know, or chased by one of her majesty's ships. what do you think?' 'i think,' said charke, who always spoke of everything connected with his calling in the most unemotional manner possible, 'i think we shall know when we come up to her, as we must do in about half an hour. while,' he continued, with a subdued tone in his voice, while his eye glinted sideways towards where bella stood, 'we are not naval officers but only humble merchant seamen. there's no prize-money for us, therefore it is not our business.' bella had, of course, been listening attentively to all that had been said since she had come on deck after running lightly up the poop ladder, and now, hearing these words about 'naval officers' and 'prize-money,' her interest became more intense than before. 'oh, uncle!' she exclaimed, putting her hand on his sleeve, 'what does it all mean? naval officers and prize-money! that's not one of her majesty's ships?' 'no, my dear,' the captain replied, 'that is not one of her majesty's ships; but i shall be precious surprised if she doesn't turn out to be one of the very craft that her majesty's ships are always on the look-out for hereabouts, only rather closer in towards the african coast than this. she has all the build of an arab slave-dhow.' 'ay,' exclaimed charke, who was still using his glass freely, from where he stood behind them. 'ay, and something more than the build, too. if i'm not mistaken, her hatches have open gratings. what do you say, fagg?' turning to his junior. 'seems so, sir,' said that young officer, who never wasted more words than necessary, 'though i'm not quite sure.' 'i am,' replied charke. 'i can see the grating slits perfectly as we get nearer.' 'what does that mean?' asked bella, to whom this conversation conveyed nothing. 'it means,' said pooley, 'that there is live stock below those gratings. black cattle, as they used to be called on the west coast. ordinary hatches, to simply cover up cargo, are not made to let the air in. cargo can do without breathing.' 'how awful!' bella exclaimed, while through her mind there ran recollections of what she had heard or read casually of the slave trade in the old days, and also of the horrors of the north-west passage. 'how awful!' 'bad enough,' replied pooley, 'though not as bad as the old west african days, nor as shocking as you might think. the slave trade is a valuable one in this ocean, and those who are carried in the dhows are well enough fed. rice, indian corn, maize, and cassava is given them for food, and they have mats and matting galore to sleep on. persian merchants and arab gentlemen don't buy starved scarecrows for their domestic servants.' 'whatever she is, and whatever her cargo is, there's something wrong with her,' the chief mate suddenly exclaimed. 'she's off the wind now, and the fellow who was at the helm has left it. it is abandoned. by jove!' he exclaimed, 'he is lying wriggling by it. what on earth's the matter?' 'and,' added the second mate, 'there's a negro woman waving a red scarf. something's wrong there, no doubt.' 'we shall be up to them in ten minutes,' the master said, all bustle and excitement now. 'let go the foretack. stand by to lower the starboard-quarter boat'; while, as he spoke, the men of the watch who had been leaning on the fife-rail rushed to the falls to be ready to let the boat sink to the water when the proper moment came. to bella this seemed the most exciting moment of her life! there, in front of her, was one of those vessels, the name of which, or class of which, was almost unknown to her, except that, from odds and ends of conversation with her lover, she had gathered that these were the things in the chasing of which part of his existence might be passed until they met once more at bombay. here, on this glistening, glassy sea, the dhow lay--her one mast raking towards her bow instead of her stern, as is the case with most vessels of the western world, and her long white triangle of a sail unfilled and flapping listlessly. a dhow--perhaps a slaver! as her uncle and the mate had said--a dhow in sore distress with, writhing by her helm, the man who had lately been steering her, and, over her bow, that negro woman waving frantically the red scarf. excitement there was, indeed, in all this; excitement which caused bella, even as she eagerly watched the vessel they were approaching, to wonder how the striking up of the band at a ball, or the ring of the prompter's bell ere the curtain rose on a drama that all london was flocking to see, could have ever stirred her pulses. what were they, those trivialities, to the smiling, glistening face of this eastern sea--to the horror and the cruelties that this now tranquil ocean's bosom had enfolded through the ages. still the negress waved, not recognising, perhaps, in her blind, besotted, dumb, animal-like ignorance that help was at hand, and still, through their glasses, they could see that he who had steered the dhow now lay motionless. then, at her ear, as the _emperor_ came within six cable-lengths of the dhow, her uncle gave a few rapid orders, the second mate, accompanied by the boat's crew, jumped into the quarter-boat--the man at the wheel luffed until the vessel had not a motion in her. swiftly the boat was lowered, the rudder and thole pins shipped, and she was on her way to the dhow. 'what do you make of it?' the master roared to fagg ten minutes later, as, by then, the _emperor of the moon_ had come closer to the dhow through the motion of the swell. 'what?' 'i don't know what to make of it, sir,' the second mate called back. 'the man who was steering is, i think, dead. he does not move, and there is a white film over his eyes. the woman who waved the handkerchief seems well, but i cannot understand what she means. she does nothing but howl and point below.' 'are the hatches grated?' 'yes, sir, and there are four negroes beneath them. it is a slave dhow for certain. the negroes are shackled and handcuffed.' 'have you searched further?' 'i am going to do so now. the ship is settling, i think. there is a kind of poop superstructure forming cabins.' 'search at once; then bring all alive on board us.' in a moment mr. fagg had disappeared into what he had termed a 'kind of poop superstructure,' and, while he was in it, all on board the _emperor_ were occupied in speculating on what could have brought a slaver so far to the east and out of her ordinary course, and also in wondering what the mate would find during his further search. but that wonderment was soon to be resolved, for, ere mr. fagg had been out of their sight five minutes, he rushed back from the superstructure to the deck, and bawled through his hands: 'there is a young naval officer lying in the poop cabin, and he is slightly wounded. his name is--is----' 'what?' roared pooley, astonished at the mate's hesitation. 'it is marked on the rim of his cap--inside. it is--i--i am afraid it is miss waldron's _fiancé_. the--the--name is bampfyld.' chapter ix come over, come home through the salt sea foam. never, perhaps, on all that old highway of the waters, that silent road along which so many had steered their course to fabled ormuz and to ind, nor amidst fierce sea-fights 'twixt arab and persian, or arab and european in later centuries, nor in the howl of storm when the waters closed around the shipwrecked and doomed, had there arisen a more piercing shriek than that which now issued from bella waldron's blanched lips. 'my god!' she screamed, repeating the second mate's words. '"the name is bampfyld!" oh, it's gilbert--gilbert! there is no other in the navy list. let me go to him, uncle!' 'no, no,' the master said, while good mrs. pooley put her arms round the girl as she stood there by the poop-rails and endeavoured to calm and soothe her. 'no, no, bella; they will bring him on board directly, then,'--and in his desire to ease the girl's heart he raised the ghost of a smile to his lips--'then you shall nurse him till he is well. yet,' he muttered to charke, as he walked over to where the first mate stood, 'yet, how on earth does he find himself in that infernal dhow!' 'heaven knows,' the other answered. 'but, perhaps, 'tis not so strange, after all. there may have been a fight between his ship and the slaver--though there's not much fight in them when they get a sight of the british flag!--or he may have been sent to board her and got cut down, or half-a-hundred things. all of which,' he added, with his now usual cynicism, 'are equally likely or unlikely. anyhow, he is here--or will be in a few moments--and we shall have him for a passenger to bombay. your niece is in luck, sir,' and he turned on his heel and went down the ladder to the deck to see to the raising of the boat, which was now making its way back to the ship. to stephen charke, still loving the girl as madly as he did, still raging inwardly at the knowledge that every knot which the ship made was bringing her nearer to the man who, as he considered, had torn her from him, this incident seemed the last and most crushing blow of all. god knows what hopes the mate had cherished in his bosom since first he had learnt that bella was to be a passenger in her uncle's ship for about four months; what ideas might have been revolving in his mind as to whether, in those four months, something extraordinary, something almost unheard of--not to be dreamt of nor foreseen--might happen to give him one more chance of winning her. he was a romantically-minded man, a man with so rich an imagination that, to him, there sometimes came ideas that few are ever burdened with. and, in that full and teeming imagination, there had been pictured to him visions of the _emperor of the moon_ being wrecked and bella and he alone spared--he, of course, saving her at the peril of his own life and winning her away from her more aristocratic lover by so doing. or, he dreamt of that lover being himself wrecked and lost, or pierced by an arab spear in some affray, or shot in a hand-to-hand fight with a particularly bold slaver (since he knew well enough that the ships of the bombay station were often enough down here) or--or--or he cherished any mad vision that first rose to his brain. and now--now--this very man, this successful rival, this aristocratic naval officer, with his high birth and future peerage, was actually being brought aboard the ship where the woman was whom they both loved--brought on board 'slightly wounded,' and his own last chance thus gone. gone for ever now! perhaps, therefore, it was no wonder he should bite his lip and smother unholy murmurs deep down in his throat; perhaps, too, he merits compassion. he had loved this girl fondly since first he set eyes on her, and once, at one time, he thought he had almost won her. then this other had come in his way, had swept him out of bella's heart, or the approach to it, and his chance was over. yet, once again, they had met through an almost unheard of, and scarcely to be imagined, opportunity, and--lo! here was his successful rival once more at hand to thwart him. it was hard on him, or, as he muttered to himself, 'devilish rough.' the quarter-boat was coming back to the ship now, fagg steering her, while, between him and the stroke oar, there lay the body of the young naval officer, clad in his 'whites.' and again as bella, madly whispering 'gilbert, gilbert, my darling,' stood by the head of the accommodation ladder--which had been lowered while the boat was gone to the dhow--the men brought her lover gently up and laid him on the deck under the awning. 'oh, gilbert!' she cried again, as now she bent over him, while stroking his hair, which, on the left side of his head, was all matted with thick coagulated blood, 'oh, gilbert! to think that we should meet thus! sir!' she screamed to fagg, who was about to descend again to the boat to fetch off the others still in the dhow, 'where is he wounded? where? have you had time to discover?' 'i have looked him over, miss waldron, and, to tell you the truth, i do not think there is much the matter with him.' 'thank god! oh, thank god!' 'that blood,' the second mate continued, 'comes from a heavy contusion at the side of his head, but the skull is uninjured. also there is no concussion--observe the pupils of the eyes are not at all dilated.' then he turned away and went swiftly down the ladder again, muttering that, if he was to save the arabs and the negroes, there was no time to be wasted. the dhow was filling fast, he added. there was a big hole in her below the waterline, and a quarter of an hour would see the end of her. and now gilbert was carried to the cabin corresponding with bella's on the port side of the vessel, aft of the saloon, and mrs. pooley, with the steward, went in to undress him, telling bella that, as soon as he was comfortably placed in the bunk, she should come and take her place by his side. whereon the girl, distracted by both her hopes and fears--hopes that the second mate was right in his surmises as to her lover's wounds, and fears that he was wrong--sat herself down on the great locker that was in the gangway, and gave herself up to tearful meditations. 'ah, if he should die!' she murmured; 'if he should die! then my heart will break.' though, as you shall see, and have undoubtedly divined, gilbert was not to die then, at least. but, by this time, other things were taking place above which were almost as startling as the discovery of lieutenant bampfyld in that slave-dhow. startling, not only because of the unexplained cause that had brought the arab slaver into this portion of the indian ocean, but also because of the strange and mysterious behaviour of those others who were now being conveyed on board the _emperor of the moon_. ere they came, however, mr. fagg had sent over information surprising enough in itself, and sufficient to prepare all on board the ship for what, a little later, they were to see. 'the owner--if he is the owner,' he cried, 'the man who fell down while steering, is dead. he is stiffening. i presume i had best leave him to go down with the dhow?' 'ay,' called back pooley. 'ay. what about the others?' 'i cannot make them out. the negress seems well enough, but terribly frightened. as for the four men below, they all appear blind. we have taken their shackles off and they grope their way about as though in the dark. my men have to lead them up the ladders--yet their eyes look clear enough.' 'have they been kept in the dark, think you, and is the sun dazzling them now?' 'no, sir. the open gratings have furnished the part of the hold they were in with plenty of light.' he paused a moment, and those in the _emperor_ saw him gazing down steadfastly to that hold; then he called again: 'we must come away now, sir. the water is pouring in. the dhow will not swim much longer.' 'do so,' answered back pooley; and five minutes afterwards the boat was on her way to the ship, laden with the rescued negroes. mr. fagg had proved right in his surmise as to the necessity for leaving the slaver at once. for, ere he came on board, she was observed to heel over a little to starboard, then to further do so with a jerk; then, suddenly, she righted until she was on a level keel--and, next, sank below the waves like a stone, the body of the dead man, who had fallen down while steering, alone remaining above the heaving waters, and being swirled round and round in the whirlpool caused by the wreck, until it too went down. creeping up the companion, their hands directed to the side-ropes by the sailors; feeling the steps with their huge splay feet--as a mule feels its way along the thin line of insecure path that rounds the smooth face of a precipice--those stricken men came; huge, splendid specimens of the swart negroes of wyassa and wahiyou and wagindo, whom the arab slaver ships from kilwa, below zanzibar, and transports to bussorah and mohamra, whence they often reach the more distant turkish harems. now, looking at them as they stood on the deck of the _emperor of the moon_, it seemed as though their course was almost run. for, though these men would never be slaves to arab or persian or turk, of what use to himself or any one else is an unhappy blind nigger who, to exist at all, must work like a dray-horse? 'poor wretches!' said pooley to charke as they both stood regarding these blacks, 'see how the shackles have eaten into their ankles. poor brutes! they say that sometimes these fellows sell themselves willingly into slavery; i doubt much if these have done so. ah, well! we must take them with us to bombay, where, at least, they will be free. i wish,' he added, 'we could communicate with them somehow and learn who and what they are.' 'perhaps,' said charke quietly, unemotionally as ever, 'lieutenant bampfyld can tell us when he comes to. since he was in the dhow, he probably knows what she was and where she came from.' then, breaking off to cast his eye around, he said: 'sir, there is a breeze coming aft. shall we not make sail?' 'ay,' cried pooley, springing to the poop, 'ay, we have had little enough wind for some days. summon the watch.' a few moments later the order to square the yards thundered along the deck; the men rushed to the braces. far off, up from the dusky, wizard south, the wind was coming as they fisted the canvas, and the _emperor_, heeling over, gathered way and sped once more towards india. she gathered way faster and faster as outer jib and topsails were loosed and sheeted home, fore and main top-gallant sails and spanker yards braced sharp up, and main-sail, main-royal and mizzen top-gallant sails set, as well as jibs and staysails. she talked, as the sailors say, as she went through the water; she hummed and sang beneath the breeze that came up from far down by the antarctic circle--a breeze whose cool breath was gone and was, instead, perfumed now by the warm spicy odours of adjacent mauritius and reunion. away, over the vast waste of golden waters she flew, and the master, standing on the poop, called down to his first mate joyfully to ask him if this would not do well enough for bombay. 'ay, ay, sir,' answered charke, turning round from giving orders to the men aloft to answer his chief. 'ay, ay, sir.' while to himself he muttered: 'bombay! india! well, when we are there, all is ended for me!' chapter x the growing terror the sailor is, as all the world knows, a light-hearted, mercurial creature. face to face with death in some form or other during every hour of his life--although, often, the mere presence of death is neither known nor suspected--he is only too elated and happy when momentarily without anything to cause him anxiety. such was the case now with captain pooley, since his beautiful ship was rapidly picking up all the time she had lost by lack of wind and delays, 'and since,' as he jovially phrased it, 'all his new passengers were doing well.' 'first and foremost,' he said that evening, as he sat at the head of his table with bella in the place of honour on his right hand, his wife on the left, and mr. fagg opposite to him, while his honest, sunburnt face gleamed rubicund beneath the inch of white under his hair which his cap had preserved from the sun, 'bella's young man is all right. then bella's new plaything, the tiger, takes kindly to its lodgings--though you will have to sell it, my child, directly we get to bombay, and distribute the money it fetches among the men. then those wretched slaves--even they will eat and drink, won't they, fagg?' 'not much of that, sir,' the second mate answered, who was eating and drinking pretty well himself, however; 'they don't care to do much of either. they make a good deal of moaning up in that deck-cabin forward which you have given them. the woman, however, seems all right. i suppose the lieutenant has not been able to tell you much about the dhow yet, miss waldron?' he asked, bending forward a little as he addressed her. 'at present,' she replied, 'we have had little conversation. he says, however, that he sent me a telegram from bombay, telling me not to start as the _briseus_ was coming down here. he only came-to an hour ago, however,' she went on, while a ravishing blush swept over her face, 'and we--we--have had so much to----' 'spare her, fagg,' said pooley, with a laugh, and passing the claret at the same time. 'spare her. suppose you woke up one fine afternoon and found your sweetheart bending over you in your berth and whispering all sorts of endearing things in your ears, as well as kiss----' 'uncle!' cried bella, while mrs. pooley touched her husband's arm reprovingly with her forefinger, and mr. fagg hid his face behind the vase of brilliant cape gooseberries on the table. 'uncle!' whereon the bluff, good-natured sailor desisted, and began to speculate on the blindness with which the rescued negroes were attacked, and on that attack being, as he imagined, a recent one. 'they capture these poor wretches inland,' he went on musingly, 'in the big lake region as often as not; but, as far as i have ever heard, blindness is not one of their afflictions. moreover, these arab owners and captains wouldn't buy blind slaves, either for selling farther north, or for using as sailors in their dhows. therefore, i take it, this blindness must have come on them since they were shipped. that's strange, isn't it?' while, as he spoke, he rose, and went to his neat mahogany bookcase which was securely fastened to one of the saloon's bulkheads, and took down the two medical works he possessed--the one dealing with all general human complaints to which our flesh is heir, and the other with tropical diseases more especially. yet neither under the heading of 'eye,' nor 'blindness,' nor 'optics,' could he find aught that bore upon the subject; nor, in his book on tropical complaints, could he discover any information that might enlighten him as to why the four negroes should be so stricken. he spoke again, however, after turning over the leaves of these erudite volumes a second time, saying: 'fever, i know, sometimes produces blindness as an after-effect, yet--well, we have all seen these fellows, and there's no fever in them, i should say. oh, deuce take this confusion of tongues!' he exclaimed irritably; 'if it did not exist we could find out so much from the sufferers themselves. bella, our only hope is in you and your patient. if lieutenant bampfyld can't tell us something, we shall never know who these men and the woman are, where they came from, what is the matter with them, and to whom the dhow belonged. can he speak anything but english, child?' 'he knows some hindustani,' bella replied; 'and, i think he said, some words of swahili. he has taken up eastern languages in the service, which was one of the reasons for his being appointed to the _briseus_. he may be some help. at least he can tell us how he came on board that horrid ship.' as she spoke, eight-bells struck on deck, and, as the sound came through the skylight, both she and mr. fagg rose, the girl doing so because it was the hour at which she intended to visit gilbert again, and the latter because it was time to relieve stephen charke, who would now come below to take his supper. for bella had fixed this hour for paying her last evening visit to her future husband because she knew that the second mate would then descend, and she was never now desirous of being more in his company than necessary. she therefore left the saloon before fagg could have relieved charke, and, going to the cabin in which gilbert bampfyld lay, pushed back the curtain that hung at the door and went in to him, while observing as she did so that he was awake and gazing upwards as he lay. and she saw that he smiled happily on perceiving her, and whispered the word 'darling' as she advanced to his bedside. 'you are better, dearest,' she said, bending over him and putting her hand on his forehead, which was cool and moist. 'much better. aunt will come soon with fresh bandages for your poor head, and then you will have a good night's refreshing sleep. and to-morrow, perhaps, you will be able to tell us how you came to be in that hideous slaver. oh, bertie!'--for so she often called him--'what a mercy it was that we found you as we did. and what a miracle that we should have met thus. home-keeping and narrow-minded people would say, if they read it all in a book, that such a thing was unnatural and impossible.' their first meeting, their joy at discovering that they had come together again in this marvellous manner; their rapture when, a few hours before, gilbert bampfyld had emerged from his stupor and unconsciousness, has not been forgotten, although the description of it has been omitted. omitted for the simple reason that most of us have been, or are, lovers; most of us have known in our time, or know now--and those are the happy ones!--the sweet, unutterable joy with which such meetings are welcomed. who does not remember the sudden, quickened beat of the heart at some period of their existence, as they met again the one they loved the best of all in this world; the creature upon whom their thoughts were for ever dwelling, and from whom those thoughts, however wandering they had heretofore been, were, at last, never more to roam! picture to yourself, therefore, what rhapsody was bella's when, forgetting everything else but that she held her lover to her heart, she wept over his salvation from an awful, swift, impending death; picture also to yourself the delirious joy which coursed through gilbert's now unclouded mind, as he found himself in her arms--with her--close to her. picture this, and no further description is needed of their meeting in that cool, darkened cabin of the old ship. imagine for yourself what your own ecstasy would have been in such or kindred circumstances, and you possess the knowledge of what theirs was. 'darling,' he said again now, as she held to his lips a cooling drink that she had brought into the cabin with her, 'darling, i can tell you in half-a-dozen sentences or less----' 'no,' she said. 'no; not now. to-morrow, when you have slept----' 'yes, now. why, dearest, i am well! i could take the middle watch to-night if necessary, or--or--do anything that a sailor may be called on to do. and as for finding me in that dhow, why, it's the simplest thing on earth--or the waters. listen. the _briseus_, as you would have learnt by that telegram i sent you if you had ever received it, was suddenly ordered to join the cape squadron--dhow-catching. and i can tell you we were not so very long before the game began, since by the time we were abreast of kilwy--which is the southern limit of the legal slave trade--we fell in with twelve dhows, one of them being our friend from which i was rescued by your people. and you may depend we were after them like lightning, while beginning to ply them with shell and shot from our little gun forward. they scattered, of course, though some got hit and lay disabled on the water, while i went off in the whaler with her crew to attack one that seemed badly knocked about. the one in which i was when found by you.' 'the horror!' exclaimed bella, with a pretty shudder. 'no, no; don't call her that, because, after all, i owe my life to her.' 'well, the angel!' exclaimed bella now, with sudden change. 'though i don't altogether know that the captain meant to save me----' 'the wretch! i'm glad he's dead.' gilbert laughed at these variations in bella's mental temperature. then he continued. 'they are artful--incredibly artful--in these dhows. they will let our pinnaces or whalers or any other of the ship's boats come alongside, then, all of a sudden, they cut their lee halliards, and down comes their great sail over us, enveloping the boat and all in it, just as if it was in a net or a bag.' 'ah!' gasped bella. 'and that's not all. when you are caught like that, they have another pleasing little way of firing at you from above through the canvas, so that you are being shot down while, all the time, you have no chance of escape.' 'oh!' exclaimed bella. 'to think of it! ah, the wretches.' 'they do, bella. fortunately, however, this one couldn't do it, being disabled, and she had, therefore, come up to the wind with hardly any way on her. this was all right for us, as i meant to board, so as we came alongside each other we hooked on to her anchor cable, which was hanging pretty low down, and we should have got on board, too, only at that moment the dhow gave a lurch which sent the whaler half-seas under, and i got a blow on the head which knocked me insensible----' 'oh, gilbert! that wound on your head!' 'i suppose so. at any rate, i knew no more about it; and i don't know anything further, now, since i was insensible till i woke up here this morning and found you bending over me. however, i'm all right now, or soon shall be.' 'but how did you come into the dhow you were found in?' bella asked, while pouring out, directly afterwards, one question after another. 'and when did it happen--yesterday, or a week ago? and where was the whaler, and the sailors, and the _briseus_? and why did they all desert you? what a nice kind of a captain yours must be, to be sure!' 'my opinion is now,' said gilbert, 'that the dhow you found me in, rescued me--picked me up. and i expect our captain--he is a rattling good skipper, bella, all the same--heard i was drowned and thinks i've missed my muster. my cousin jack will imagine for a month or so--till we get in to bombay--that he is the future lord d'abernon,' and he laughed as he thought of how soon cousin jack would be undeceived. 'but the dhow we found you in--how did she escape, and why didn't the _briseus_ capture her?' 'some must have got off in the confusion since it was only an hour from dark. i'm certain to be reported lost when the ship goes into either zanzibar or aden, and---what's that?' he exclaimed, breaking off suddenly. 'surely that's your uncle's voice!' he recognised it because captain pooley had been in to see him after he recovered his consciousness and had congratulated him on doing so, as well as on being practically restored, while saying also that he was delighted at being the means of rescuing him out of the sinking slaver. 'yes,' bella replied, 'that's uncle's voice; and the other is that of mr. charke, the first mate.' 'listen! what is it he is saying?' it was perfectly easy to hear what he was saying, since both master and mate were conversing in the saloon, to which charke had descended. and the words which reached their ears, as they fell from the latter's lips, were: 'oh, no doubt about it whatever, sir; not the least. the negress is now as blind as the negroes themselves. she cannot see her way along the deck, nor any of the signs we have made before her eyes.' chapter xi the terror increases the southerly wind did not hold as it should have done considering the time of year, and the consequence was that the _emperor of the moon_ was by no means making such a passage as was to be expected of her. indeed, by the time that the second day had passed since the rescue of gilbert from the slaver, and when the evening was at hand, she was almost motionless on the water, while such sails as were still left standing hung as listlessly as though they were suspended in a back room. now, this was disheartening to all on board--that is to say, to all except one person--as is generally the case when such things happen. the master was grieved because he looked upon the delay as an absolute waste of valuable time, while as for bella and gilbert--well, it is scarcely necessary to write down here what they were looking forward to at the end of their journey, or what visions haunted the mind of the latter concerning the cathedral in bombay and a ceremony of marriage being performed at the altar-rails by the bishop. yet, all--passengers, master, officers and men--had to swallow their disappointment as best they might, and to recognise the fact that bombay was still over three thousand miles away and not likely to be reached for very many days. the one person who was, however, resigned to the affliction of delay was stephen charke, in whose brain there still lingered a wild and chimerical idea that there might yet be sent by fate some extraordinary piece of good fortune which would, even at the last moment, sever gilbert and bella, with the subsequent result of bringing him and her together. it has been said that he was a dreamer, and never had he been so more than now, since, sleeping and waking, he still mused on the possibility of some extraordinary set of circumstances arising which should force the girl into his arms. yet, he had to own to himself that nothing was more unlikely than that any such circumstances could by any possibility arise. if anything visited these seas, this stupendous ocean, at this period of the year, it was most likely to be a flat calm such as that which they were now experiencing, instead of storms; and, even if storms should come, of what avail would they be to separate gilbert bampfyld and bella waldron? 'i am a fool,' he would mutter to himself, as he smoked his pipe in either the solitude of his own cabin or on the deck at night, 'a fool. a madman! one has only to observe how they love each other, how they never leave each other's side, to see that nothing could ever bring her to me. even though she and i were cast on some deserted shore, even though i saved her from forty thousand threatened deaths--even though bampfyld himself were dead and buried, she would never give herself to me. i am,' he would repeat again, 'a fool.' and this acknowledgment would, for a time, operate wholesomely on him--a man whose mind was not altogether that of a visionary and whose heart was not, by nature, a perverted or warped one--and he would resolve that, henceforth, he would think no more of this girl for whom his love was so fierce and, to him, so disturbing. he made resolutions, therefore, and kept them--until the next time that he saw the lovers together, smiling, talking, happy in each other--'billing and cooing,' as he called it, with a smothered curse. they were on deck together, now, on the evening of the second day of calm as stephen went up to take the first watch, since gilbert had refused to remain a prisoner in the cabin allotted to him for more than twenty-four hours, and pooley was also there, fagg being below finishing his supper. mrs. pooley sat on the poop in a deck-chair engaged in some needlework she had constantly on hand, and, forward, the men were engaged in smoking and telling yarns, while the general idleness which pervades the forecastle when a ship is becalmed prevailed everywhere. one man was reading a short story to his mates out of a country paper six months old, another had a sewing-machine between his legs with which he was mending his and his comrades, clothes, a third was teasing and playing with 'bengalee,' the tiger cub, which was growing--or seemed to be growing--fast. at present, however, it was safe to let it loose since it had no more strength than a large-sized cat, and teeth not much bigger than those domestic animals possess. generally, the creature followed bella about wherever she went, rolling down the companion ladder after her like a striped ball when she went below, or lying on the edge of her dress when she sat on deck; but at night it was shut up in a locker forward and looked after by the sailors. the hour for its temporary retirement had not, however, yet arrived, wherefore it was still gambolling about amongst the men. altogether, the vessel presented a peaceful scene as she lay 'idle as a painted ship upon a painted ocean,' while, from forward, there came the droning voice of the sailor who was reading the storiette to his mates, interrupted only by the laughter of the others at the cub's leaps and growls; and, from the after part of the ship, the talk of the 'quarter-deck' people arose. 'come,' said pooley now, addressing charke, 'come, let us go and look at those unfortunate niggers. the lord knows what is to become of them. the woman, you say, never rises from the floor of the cabin, but only lies there and moans. it is the strangest thing i ever heard of in my life. i wish, mr. bampfyld,' turning to that gentleman as he passed with bella, 'that you could give us some information about that dhow we found you in.' but, of course, gilbert could tell them no more than he had already done a dozen times, while repeating in substance all that he had said to his _fiancée_. 'i am sorry,' he had said on each occasion, and again said now, 'but i know absolutely nothing. i was insensible when i was taken into the dhow--as taken in i must have been, since i could never have got in by myself--and, as you are well aware, i was insensible when i was brought out. i positively know nothing.' 'the helmsman's death was as strange as anything,' pooley observed. 'fagg says there was no wound about him that he could see. what, therefore, could he have died of?' 'sunstroke, i imagine,' the first mate said, in his usual emphatic, crisp manner. 'sunstroke. it could not have been fever, otherwise these negroes would have it, too. yet,' he went on, in a manner more meditative than usual with him, 'those arabs, if he was an arab, rarely suffer from that. it takes a white man to get sunstroke.' 'well, come,' said the master again, 'let's go and see to them. the sun is on the horizon; it will be dark in a quarter of an hour's time.' whereon he strode forward, accompanied by charke, while mr. fagg, who had come up from the saloon, began to keep such watch as was necessary. and gilbert, bidding bella go and sit with mrs. pooley, strode after them, since he was anxious to have a look at the unhappy creatures who had been rescued at the same time as himself. the male blacks had been put into a deck cabin (in which was usually kept an assortment of things such as spare lamps, a boat sail or two, and mr. fagg's bicycle, on which he disported himself whenever he got ashore anywhere), wherein some matting had been thrown down for their accommodation. and, as now they neared this cabin, they heard sounds proceeding from within it which were really moans, but, to their ears, had more the semblance of the bleating of sheep. also, it seemed as if one of them within was chanting some sort of song or incantation. 'we shall have to stop this noise in some way, sir,' charke said to the captain; 'it has been going on more or less ever since they came on board, and the men complain that it disturbs them in the fo'c's'le. it's a pity we can't communicate with them somehow. perhaps lieutenant bampfyld might try, as he says he knows some words of swahili'; while as he spoke he looked at the man who had once more, as he considered, or chose to consider, stepped in between him and the woman he loved. yet, because he never forgot that he was a gentleman born, there was nothing in his manner that was otherwise than polite when he addressed gilbert. 'i have tried,' said the latter, 'more than once to-day. and either my swahili is defective, or that is not their language. i suspect that it's galla, of which i do not know a word.' meanwhile, the captain had drawn back the cocoanut matting which hung in front of the deck cabin door, though, after peering into the sombre dusk for a moment, he started back, exclaiming: 'good heavens! what has happened now? have they murdered one of their companions, or what?' it was, in truth, a weird sort of scene on which he, as well as gilbert and charke, gazed, as the swiftly-failing tropical evening light illumined the interior of the cabin. flat on the floor of it lay one of the negroes, undoubtedly dead, since there was on his face the gray, slate-coloured hue which the african assumes in death. yet his eyes were open, only now, instead of that bright glassy look which all their eyes had had since they were brought on board, there was a dull filmy look, which told plainly enough that there was no life behind them. still, dead as the man undoubtedly was, he did not present the most uncanny spectacle of all within! that was furnished by those who of late had been his comrades, and by the strange grotesqueness--a grotesqueness that was horrible in itself--of their actions. all three of the living negroes were on their knees in the cabin, which was roomy enough to amply admit of their being so, while, with their great black hands, they were pawing the man all over, feeling his breast and body, and endeavouring to bend his fingers and toes as well as his legs and arms; while, even as they did so, from their great mouths came that moaning incantation which resembled so much the bleating of sheep. doubtless they felt almost sure that their fellow-slave was dead, and these actions were being performed as tests. yet, also, there was a solemn, wild unearthliness attached to the whole thing by the manner in which, when one of the visitors standing at the door and peering in made a remark, all turned their sightless eyes towards that door and then held up each a hand, and emitted a hissing noise through their great pendulous lips, as though enjoining silence and respect for the dead. they held up those hands with the fingers stretched enormously apart and with the palms towards the intruders. their eyes were bright enough as they glared at the three white men outside, whom they could not see, yet, somehow, the gleam in them and the knowledge that they were sightless gave so creepy a feeling to those regarding them that they could not restrain a shudder. 'what in god's name is it?' exclaimed pooley, he being the first to speak. 'what? what horrible disease that blinds them to commence with, and then kills--and kills not only negro, but arab--captured and captor? who--which--will be the next?' as he spoke, a thought struck each of the three as they stood there gazing at one another in the swiftly-arrived darkness of the tropical night--a thought to which, however, not one of them gave utterance. _who_ would be the next? an arab had died from some strange, unknown disease in the ship wherein these men had been found, and, now, one of them, too--a negro! had, they reflected, this insidious horror been, therefore, brought into a ship full of white men? would they also fall victims to that which had killed the others? that was the thought in their minds--in the minds of all of them, though not one gave voice to that thought. 'he must be got away from them--taken out of that cabin,' pooley said, his speech a little changed now, and more husky and less clear than usual. 'perhaps the woman, the negress, may be of some avail. i doubt if they will let us remove him without difficulty--though--poor blind things as they are--they could scarcely make any resistance. go across to the other cabin, mr. charke, and fetch her over.' he had been anticipated in his order, however, by the chief mate ere he spoke, charke having, through some idea of his own, already crossed the deck to the opposite cabin in which the woman was placed. therefore, as pooley looked round to see why the mate did not answer him, he saw in the darkness that he was returning; while he perceived--even in this darkness, which was not quite all darkness yet, and by the light of the foredeck lantern--that charke looked pale and agitated. 'the woman,' he said, 'is dead, too, i believe. she is lying on the cabin floor motionless--and cold.' chapter xii 'stricken' it was from this time that there began to creep over the ship a feeling shared by all, both fore and aft, that the voyage would not end without something untoward happening. what form, however, any misfortune which might come to them would be likely to take, none were bold enough to attempt to prophesy. yet, all the same, the feeling was there, and, since every man on board the ship was a sailor, while, for the ladies, one was a sailor's wife and the other a sailor's future wife (each of whom was certain to be strongly receptive of the ideas and superstitions of her own particular sailor), it was not very strange that such should be the case. and, there was also in the thoughts of all that idea to which none of the men congregated outside the cabin, when the negro had been found dead, had ventured to give expression--the idea that the unknown, insidious disease--which had struck him and the negress, and also, possibly, the arab _negoda_ down--might eventually seize on them. there were, however, at present at least, no symptoms of anything of the kind happening. all on board continued well enough, and, up to the time that the man and woman had both been buried in the sea for more than twenty-four hours, no complaints were heard from any one of feeling at all unwell, while the three remaining blacks seemed no worse than before. yet, it was a pity, perhaps, that at this time the ship should still have been forced to remain becalmed and almost motionless; that neither from south nor west any breeze blew--from the north and cast there was scarcely a possibility of wind at this season--and that, except for the strong southern current which carried her along at a considerable though almost imperceptible rate, she hardly stirred at all. a pity, because it gave the sailors too many idle watches wherein to talk and chatter, to spin yarns of old-time horrors which had fallen upon vessels in different parts of the world, and to relate strange visitations which they had either personally suffered under or had 'heerd tell on,' and so forth. nor aft, in the saloon, did those who used it fail to discuss the strange circumstance of--not so much the death which had stricken the africans--as the blindness that had fallen upon them. and here, stephen charke, better read perhaps than any of the others owing to his studious nature, was able to discuss the matter more freely than either the captain or those who sat at his table. 'i do distinctly recollect reading somewhere,' the mate said one evening, as all sat under the great after-deck awning, fanning themselves listlessly, while fagg worked a kind of punkah which his ingenuity had devised, 'i do distinctly recollect reading somewhere of all those in a ship, on board of which was a large cargo of west african negroes bound for america, being stricken with blindness. i wish i could recall where i read it. in that way we might be able, also, to find out how to take some steps to avoid the same thing happening to us in the old _emperor_.' 'a cheerful prospect, truly,' said the captain, 'if that is to occur'; and as he spoke he roamed his eye around the tranquil, glassy sea, on which there was not so much as a ripple. 'a pleasant thing, indeed, if one-half of us get blind and a rough time comes on. how, then, is the ship to be worked three thousand miles. how are the sails to be attended to?' and now he directed his eyes aloft to where all the canvas was neatly furled with the exception of the studding sails. 'we'll hope it won't be as bad as that, sir,' said fagg. 'only the black people, and those out of another ship than ours, seem to suffer. until one of us,'--by which he meant the europeans on board--'gets affected we haven't much to fear, i take it. while, you know, sir, we can find shelter before we reach bombay. there are the seychelles, for instance, from which we are not so very far off.' 'such a delay as that would mean a very serious loss for me,' pooley replied. 'as it is, i expect, one way or another, i shall miss one voyage out of two years.' 'i hope not,' said gilbert bampfyld, seriously, 'otherwise i shall begin to think it was a pity you ever came in contact with the dhow in which you found me.' yet, as he spoke, he saw bella's beautiful eyes fixed on his face, and knew that no more crowning mercy had ever been vouchsafed to any two mortals than had been accorded to his sweetheart and himself by his rescue. 'well,' said pooley, 'we won't talk about that. i am devoutly thankful that we were enabled, by god's mercy, and also by the aid of something which is almost a miracle, to rescue you. for the rest a sailor must take all that comes in his way and never repine. the _emperor_ has been a good old tank to me; pray heaven she continues so to the end.' then he suddenly stopped and peered forward under the awning towards the forecastle, where, beneath another awning, the sailors had been lying about, some sleeping, some chatting idly, and most of them--even to those who had dropped off--with a pipe between their lips. 'what's that commotion forward?' he asked, addressing himself to charke, who, ever on the _qui vive_ as became a chief officer, had sprung to his feet and was gazing keenly towards the foredeck. 'what's the matter with the men, and why are those three holding wilks up like that?' 'forward there!' sang out charke in a voice like a trumpet, as he, too, saw that which the master had described, namely, three of the hands standing up round the man named wilks, and one grasping him on either side, while he himself pushed his arms out before him in a manner that implied a sort of doubting helplessness on his part. 'forward there! what's the matter with that man?' 'he says he can't see, sir,' roared back another man on the forecastle deck, pulling his hair to charke as he spoke. 'he was asleep just now; and then, when he woke up, he asked what time o'night it was because it was so dark.' 'my god!' exclaimed pooley, while the faces of all around him took on a blanched, terrified look, and bella, with the beautiful carnation of her lips almost white now, grasped her lover's arm. 'my god!' then he turned to fagg and muttered, repeating the other's words: '"not much to fear until one of us gets affected." heavens! we haven't had long to wait!' while, following charke who had already gone forward, and followed by fagg, he went towards the forecastle. his mates were bringing wilks down the ladder now, since charke sang out that he should be taken into the comparative darkness of their quarters at once, thereby to escape the glare of the sun; and not one of those who were eagerly watching his descent but observed how like his actions were to the actions of the blind negroes when they were brought off from the dhow, and the actions of the others to the behaviour of the men who had assisted them to come on board. for his companions directed his hands to the ladder's ropes even as the blacks, hands had been directed; while in each of his motions was the same hesitation, followed by the same careful grasping of the rail, as there had been in the motions of the slaves. 'oh, gilbert,' bella exclaimed piteously, as she clung to him, 'what is going to happen? what is hanging over us? supposing--supposing----' 'what, darling?' 'that--oh, i don't dare to say what i dread. but if this terrible thing should spread all through the ship. if uncle, if you, if all the sailors were attacked. and you--you--dearest; you, my darling.' 'let us hope it will not come to that. besides i, personally, matter the least of any----' 'bertie!' she almost shrieked, alarmed, 'when you know that those others--some of them at least--that those poor black creatures have died after it. and you say that you matter the least of any; you, whom i love so.' 'i meant as regards the ship. i am not one of her officers, nor concerned in the working of her; and bella, dearest bella, don't get those dreadful ideas into your pretty head. never give way to panic in an emergency. doubtless some more will find their eyesight leave them--temporarily--but it can scarcely be that all will be attacked. and as regards death following, why, those other niggers are all right, and they are just as blind as those who have died!' it happened--as so often such things happen in this world--that he spoke a little too soon. he hit upon the denial of the likelihood of a possibility occurring which, by a strange decree of fate or chance, was, at the very moment of that denial, to occur; since, just as the repudiation of such probability was uttered by him, and before the men helping wilks had had time to get him comfortably into his berth in the forecastle, there arose once more that strange, weird, moaning kind of incantation from the deck-cabin in which the remaining negroes were, that had been heard before by all. and, added to it, was something more than any had heretofore heard, namely, a series of wild turbulent shouts in the unknown barbaric tongue used by the africans--shouts that seemed to issue alone from one of their throats. a noise, a bellowing, in which, though on board the _emperor of the moon_ there was not one person who could understand the words that voice uttered, all recognised the tones that denote fear, terror, and misery extreme. instantly, so stridently horrible were those cries, every one of the englishmen about rushed towards the cabin, pooley and charke being the first there, while gilbert, running forward from the afterpart and along the waist, was soon by their sides. and then, looking in, they saw that the poor blind, excited savage who was emitting those shouts had, in truth, sufficient reason for his frenzy. he seemed--he was, indeed--demented, as, with both his great hands, he felt all over the bodies of his comrades who were lying lifeless on the cabin deck, and presented an awful appearance to those who gazed on him as his great features worked in excitement, his vast mouth, with its adornment of huge white teeth, opened and shut like a wild beast's at bay, and his blind, but brilliant, eyes glared hideously. that he was nearly mad with fright and terror was easily apparent, since, while recognising without seeing that there were others near, he snarled and bit at the space in front of him, and struck out with his fists or clawed at the air with his enormous hands. 'he will spring out at us directly,' charke said, drawing to one side of the cabin. 'the fellow is mad with fear or grief.' then, ready in expedient as ever, he ran the cabin door out of its slide and shut in the negro with his dead companions. nor did he do so too soon, since, a moment later, those without heard the huge form of the man leaping towards the door; once they heard him slip, as though he had trodden on the body or one of the limbs of those lying dead on the floor; and then there came a beating and hammering on that door which seemed to promise that, in a few seconds, the panels would be dashed out and the maddened black be among them. 'this is too awful,' muttered pooley. 'is he really gone mad, do you think?' he asked, appealing to charke, gilbert and fagg at one and the same time. 'no doubt about it,' they answered together. 'no doubt. and if he once gets out to the deck, sir,' said charke, 'a dozen of us will not be able to hold him.' 'we must capture him if he does. better throw a rope round him somehow. if he were not blind, we should have to shoot him. ha! see, he has smashed open the panel! stand by there, some of you men, to catch him as he leaps out.' while, even as he spoke, the gigantic madman, with another howl, broke down the door and sprang amongst them. chapter xiii 'spare her! spare her!' mrs. pooley, bella and gilbert sat alone in the saloon that night, the faces of the two women being careworn and depressed in appearance, while on that of the young naval officer was a look, if not of consternation, at least of doubt and anxiety. that all of them should present this appearance of perturbation was natural enough, because by this time it was impossible to suppose that any less than a calamity was impending over the _emperor of the moon_ and all in her. two more men, named burgess and truby, had been attacked with blindness, while the negro, who had been the last survivor amongst the slaves, was himself now dead. 'it was too awful,' said gilbert, who had come below to tell the ladies that which had happened above, since to keep silence on the subject was useless, in consequence of the turmoil in the ship which had accompanied the poor creature's last moments. 'he died a raving maniac--nothing short of that. you heard his howls and yells after we had got him safely tied up; _we_ saw a sight that i, at least--and i should think everybody else--hope never to see again. even roped as he was, his leaps and convulsions were something shocking. thank god, they soon came to an end. i believe he died of the exhaustion caused by his mania.' 'what is to become of us all?' asked mrs. pooley sadly. 'what? the ship moves only by the current; my husband said just now that, if things go on and get worse, there will be none left to control her when the wind does come.' 'the trouble is,' said gilbert, 'that, if they make sail when the wind springs up, there may be no men to take it in if that wind comes on too strong. and, at all events, it will be serious if more men are attacked. i have offered my services in any capacity if wanted, and will serve either as officer or man if captain pooley will let me.' bella threw an admiring glance at her lover in approval of what she, in her own mind, probably considered his noble disinterestedness; then she said: 'but surely all are not going to be attacked one after another in this way? and if so, uncle can't possibly think of trying to get to bombay when the wind does come.' 'i have suggested the same thing to him that fagg did this afternoon--namely, the seychelles. they're all right, and the climate is first-rate for the tropics. he says, however, he will see what happens by the time we get a wind. he won't give in if no more men are attacked.' meanwhile, even as he spoke, each of the trio were occupied with thoughts which they would not have cared to put into language. mrs. pooley's were those good wifely reflections which busied themselves only with her husband's interests, and were disturbed by considerations of what a loss to him the delay would produce should it be further prolonged. yet, there was also growing upon her, if it were not already full-grown--as was now the case with all others in the ship--a gruesome, indefinable horror of what might be the outcome of this strange affliction that had fallen on the vessel. suppose, she had asked herself a hundred times in common with all the others on board--the sailors alone expressing their thoughts openly--suppose everyone in the _emperor_ succumbed to this blindness! what then would happen, even if it were not followed by death? would they drift about the ocean helplessly if the calm continued, until they were seen and rescued by some other vessel; or, if a strong gale came up, would they--with no one capable of so much as steering the ship be shipwrecked and sent to the bottom? while, as to the horrible idea of death following on blindness, and the _emperor of the moon_ drifting about, a floating catacomb--that was not to be thought about! it was too fearful a thing to reflect upon and still preserve one's sanity. yet, all the same, not only was it thought about but talked about among the sailors, while many ideas were propounded as to what was to be done ere the worst came to the worst. as for bella, her reflections were all of one kind, and one only. would gilbert be spared! for herself she cared but little, though she would scarcely have been the brave, womanly girl she was if she had not repined at the dark cloud which had now settled down over the existence of her lover and herself, and which threatened, if it continued to hover over them and their fortunes, to darken that existence still more. further than this she did not dare to look, and, consequently, could only pray fervently that the cloud might be lifted ere long, even as she strove to force herself to believe that such would undoubtedly be the case. yet gilbert's meditations were perhaps the most melancholy and bitter of any of the three persons now assembled in the saloon--brave, self-reliant young officer as he was, and full of hope and belief in many happy years still to come and to be passed in the possession of a beautiful and devoted wife, as well as in the service of a glorious profession. for he could not disguise from, nor put away from, his mind the recollection that, with his coming into this ship, with his rescue, there had come also that intangible, mysterious disease which was striking down those around him one by one at extremely short intervals; and, although he knew that he was no more responsible for its presence than if he had never been found in that accursed dhow, he began to think that there were many in the _emperor of the moon_ who would regard him as being more or less so. which, in truth, was a weak supposition, born in his usually strong, clear head by the calamities now happening with great frequency one after the other; a supposition shared by no one else in the ship. for--as he himself knew very well, yet took no comfort in knowing--had he not been in the dhow her other inhabitants would have been rescued all the same and taken off by pooley, and would have brought on board with them the infection which was now supposed to be at the root of the disasters that were happening. the meditations of all three were now, however, disturbed by the descent of stephen charke to the saloon, he being about to eat his evening meal before taking the first watch. as usual and, almost, it seemed, unjustly so--since never had he said any further words to bella which she could construe into an approach to anything dealing with his regard for her--his appearance was unwelcome to her. he seemed, however, to be entirely oblivious of what her sentiments towards him might be, and, after giving a slight bow to both ladies, rang the bell for the steward to bring him his supper. then, as he seated himself at the table, he said: 'i fancy we shall have to avail ourselves of your offer of service after all, lieutenant bampfyld, and in spite of our having refused it an hour ago. fagg,' he went on, as he cut himself a crust from the loaf, 'is attacked with blindness now.' 'great heavens!' exclaimed gilbert, while bella, scarcely knowing why, burst into tears and hid her head on mrs. pooley's ample shoulder. 'yes, it is too awful. so is payn, the bo'sun, attacked.' 'my god!' and now mrs. pooley's fortitude gave way too, and she sobbed quietly to herself until, recognising that two tearful women were scarcely in their proper place in the saloon with these young men, she rose, and, taking bella with her, they went off to their cabins. 'the watch, of course,' went on charke, 'is nothing now with the ship at a standstill. yet one has to keep it more or less. fagg's turn would have been the middle of to-night, but if you like to fall in you can take the first, and i'll----' 'thank you,' said gilbert quietly, 'but i have done plenty of watch-keeping, both before and after i was a flag-lieutenant. the middle watch won't hurt me. i will relieve you at midnight.' 'as you like. of course, the skipper and i recognise that it is a great obligation on your part----' 'oh, rubbish! we are absolutely and literally "all in the same boat" now, and we've got to make the best of it.' then gilbert rose and said: 'by the way, i should like to go and see that poor chap, fagg, if he is in his cabin. he's a nice young fellow.' 'he is, and a good sailor, though he doesn't make any fuss. lord knows what's going to be the end of it all. i hope to heaven those who are struck won't go the way of those niggers, and that their sight will come back before long.' 'i hope so, too; or else this will be one of the most awful calamities that ever fell upon any ship on a voyage. and the worst is, no one knows what the end is to be.' then he turned on his heel and moved away with the intention of going to fagg's cabin, while charke, who was now half-way through his supper, went on steadily with it; yet, as gilbert reached the gangway outside, the other made a further remark. 'by-the-by,' he said, 'another strange thing has happened. that infernal tiger-cub of miss waldron's--her pet!--seems going the same way as the others. it is crawling about the foredeck in a half-blind fashion, and evidently can't see signs made before its eyes. as far as the little beast goes, i shouldn't mind seeing it fall through one of the scuppers back into the sea it was dragged out of. it was rather rubbish to save it at all!' the words 'that infernal tiger-cub of miss waldron's' grated somewhat on gilbert's feelings, as did also the brutality of the remark about its falling into the sea. why this was so he did not know, unless it was that he had seen the interest bella took in the little creature, and in feeding it and calling every one's attention to the extraordinary manner in which it seemed to grow almost hourly. nevertheless, the observation did grate on him, and he began to tell himself that he did not care much for stephen charke. however, like a good many other young naval officers, he had thoroughly learnt the excellent system of controlling his thoughts in silence, wherefore, without making any further remark than saying that he was sorry to hear about 'bengalee,' he went on his way towards mr. fagg's cabin, leaving the first mate to finish his supper by himself. he left him, also, to some strange meditations which, had they been uttered aloud in the presence of any listener, might have caused that person to imagine that he was the recipient of the babblings of a visionary. put into words those musings would have taken some such form as this:-'supposing this malady or pestilence, or whatever it is, should be followed by madness and death, as was the case with the negroes. and supposing also that, among those who are struck, our friend lieutenant bampfyld--the future lord d'abernon!--should be one. what happens? bella'--for so he dared to call her in his thoughts and to himself--'bella is deprived of him. suppose, also, that the whole management of the ship falls into my hands; pooley may be attacked, too--then--then--then----' but here his mental ramblings had to come to a conclusion, because, wild as his riotous thoughts were, his mind was clear enough to perceive that he was just as likely to be attacked by the blindness as was either pooley or bampfyld. while he saw very plainly that so, too, was bella. and this pulled his meditations up with a jerk, since he could imagine nothing more horrible that could occur now than that the majority of all the men on board should remain sound and unstricken, and capable of working the _emperor of the moon_ safely into some port or other, while the beautiful girl whom he worshipped and adored so much should succumb to the hateful affliction. 'oh, my god!' he almost moaned aloud, 'if--if she should be the next. if she should be taken and we left. how--how could i endure that?' and then, because he was a man with the best of impulses beneath all the gall which had arisen in his heart at losing the girl he had once hoped so much to win, he moaned once more: 'not that--not that. spare her, at least, heaven! spare her, even though i have to stand by and see him win her after all. spare her! spare her!' chapter xiv struck down but still the days went on and no wind came--the one thing which, even now, after they had been becalmed for nearly a week, might have saved the ship from any fearful calamity that was at last, almost without a doubt, in store for her. for, according to their reckonings, taken regularly both by aid of the brilliant sun which still poured down its vertical rays upon them, and also by the use of a cherub log which they possessed, as well as the ordinary ones, the current had drifted them some three hundred miles north, so that they had consequently the northern coast of madagascar on their port bow, as well as the aldabra islands, and with galega, providence and farquhar islands almost directly ahead of them. only--the wind would not come, and the ship lay upon the water as motionless, except for the current, as though she had been fixed upon the solid and firm-set earth. and, meanwhile, the blindness which had seized upon one man after another was still continuing its progress, and more than half--indeed, three-parts--of the complement of the _emperor of the moon_ were now sightless. of seventeen sailors, eleven were down with this terrible, paralysing affliction, as well as one officer, mr. fagg; so that, if now the long-hoped-for breeze should spring up, there were scarcely enough men in the whole vessel to set the sails, even including pooley--who certainly could not go aloft with safety!--and charke and gilbert; while, presuming all of them could do so and the wind should freshen much, they would undoubtedly be far from able to take them in again. and then the result must be swift--undoubted--deadly. the ship would rush to her destruction, would be beyond all control; she would either go over under the force of the elements, or be dashed to pieces on some solitary coral island which she might encounter in her mad, ungovernable flight. consequently, there remained but one chance, and one only, for her, that chance being to forgo the advantage of the wind when it came at last, and to let her drift under bare poles until they were seen, and perhaps rescued, by a passing vessel. but, again there arose the fear in all hearts, as already it had done before--namely, would any other ship which might encounter them be willing to take on board men in such a plight as they were, and suffering from a disease that none could venture to doubt must be contagious? meantime, the life in the vessel itself was, possibly, the strangest form of existence which has prevailed for many a long sea-voyage. for she was subject to no stress whatever of weather, the elements were all in favour of her safety, if not her progress; she was comfortable and easy and well found with everything of the best--since, in the _emperor of the moon_, there was neither rotten pork nor weevily biscuits for old shellbacks to grumble and curse at and mutiny over, as those who wish to make the sailor dissatisfied with his lot are too often fond of representing to be the case--every one was well housed and well provided with good, wholesome food. yet, all the same, she was a stricken ship--stricken, in truth, by the visitation of god; smitten by the hand of god with a curse which none could understand or explain. fortunately, however--if the word fortune may be used in connection with those now in her!--this curse seemed to have stopped at the blindness--though god knows that was bad enough! death did not seem to be following after it, nor madness, nor delirium, as had been the case with the others--certainly as death had been. those who were down lay in their berths, blind, it is true; but otherwise there was nothing else the matter with them; and, since they were ministered to by those who, up to now, had themselves escaped the visitation, they did not suffer in any other way. bella and mrs. pooley were at this time more or less in charge of the provisions, the latter dealing out the men's rations under the orders of her husband, while bella, arrayed in a long white apron which gave her a charmingly strange appearance in the eyes of all who beheld her, attended to the meals of those who used the saloon, took her place in the cook's galley--the unfortunate man being one who was down with the scourge--and saw to all preparations necessary for their now hastily devised and uncomfortable meals. 'she's a good 'un,' the six remaining healthy men muttered to themselves, as they saw her busying herself about the ship, making soup and broth for them as well as for the after-cabin, and working indefatigably from morning to night on behalf of all on board, 'a real good 'un. and this here navy lieutenant what's to marry her is a lord, ain't he, bill?' 'he ain't a lord yet, but he's a-going to be. ah, well; if we ever all gets safe into port, her ladyship will know summat about what her servants ought to be like. her cooks won't get to windward of her in a hurry, i'll go bail!' 'if we ever get safely into port!' that was the sentiment which pervaded all minds on board the _emperor of the moon_ at that time. 'if they ever got safely into port!' for all on board began now to doubt whether they would do so. the eighth day of their being becalmed had come, even as those forecastle hands discussed the girl's goodness--with also, in whispers, many an admiring remark on her beauty and generally trim-built appearance--the eighth day had come and, suddenly, just as the forenoon watch was over, two more men suddenly called out together that they were 'struck'--were blind! two more, leaving now only four sailors and three officers--counting gilbert in place of fagg--and two helpless women! 'well,' said the chief mate, coming up to where gilbert and bella were discussing gravely this new affliction, while close by them the usual business was going on of getting the two fresh cases into their berths in the forecastle--which was now a lazaretto--'well, this ends it. the wind may blow as much as it likes now, we shall never be able to make sail. we must drift about till we are picked up or----' then, seeing the look of terror on bella's face, he refrained from finishing his sentence, saying instead: 'if we had as many hands to do one man's work as you have in her majesty's service, lieutenant bampfyld, we should still be all right.' 'i don't know,' gilbert replied coldly, and in a manner which, quite unknown to himself, he had been gradually adopting of late towards his unsuspected, would-be rival. 'i don't know. we may have a dozen hands to do one man's work in our service, as you seem to suggest, and as is often supposed, yet, all the same, i'd back four of our men and two young officers to get a lot of sail on a ship of this size, anyhow!' 'they might. yet, clever as they are, you wouldn't like to back them for much to furl those sails again if the breeze freshened into a strong wind, would you?' 'i think so,' said gilbert, still more coldly. 'at any rate, i'd back them to have a rare good try.' 'try!' exclaimed charke. 'try! oh, we can all try! as far as that goes, i'd have all the blind ones out to put their weight on the braces while the rest went aloft, if the wind would only come; they could do that without seeing. and we could try getting the sails off again if it blew too hard--but i doubt our doing it. any one can try.' after which he walked forward to make inquiries about the two fresh cases of blindness. 'i don't like that man, bella,' gilbert said when the other was out of hearing, 'although he's a smart officer and a gentleman. and i don't think he likes me.' for a moment she stood there saying nothing, and with her eyes cast down on the soft pitch of the seams, which was greasy and seething under the fierce sun. then she looked up at her lover and said: 'no more do i much now, bertie. in fact, i almost fear him.' 'i wonder if he was ever in love with you?' bampfyld said, while remembering, as she spoke, how once, in those delicious days when they had first acknowledged their own love for one another, she had jokingly told him that he was not the first sailor who had tried to woo her. and he recalled, too, the fact that charke had been introduced to her mother's house by her uncle, and had been more or less of a frequent visitor there. 'was he, bella?' he continued. 'was he the sailor you once told me of who wanted your love?' 'yes,' she said, gazing up at him with her clear, truthful eyes. 'he was. he told me so long after i met you. and i believe now--i have thought so for some time--that he would never have applied for the position he holds in this ship if uncle hadn't told him that i was coming in it. he was far too ambitious for such a post when i first knew him, and aspired to be captain in one of the great liners, and eventually to be an owner.' 'i'm glad you've told me, darling. especially as it quite explains his not liking me over much. poor chap! i can understand that he should not do so in the circumstances,' he added, while gazing down on his sweetheart with such a glowing look of love as to cause her to forget all their unfortunate surroundings and revel only in her delight at being so much beloved by him. 'yet,' gilbert continued, 'i can't understand his wanting to come into this ship, even though it would give him three or four months more of your society. such a thing as that would have been maddening to ordinary men--i know it would have been to me! if you had rejected me--i--i--well, there! i can't say what i should have done; but, at any rate, i couldn't have borne the torture of being in your presence--especially if you were on your way to marry another fellow.' 'he is a strange man,' bella said, 'and although i never loved him, i cannot help admiring his force of character. his father, a selfish old man, treated him badly and baulked him of going into your service, yet he managed to be a sailor in another way, and to enforce respect from every one. and he is a cultivated man and wonderfully well read. still, i don't altogether like his force of character, or rather, the direction it takes. he told me, on that day at portsmouth, that he never faltered in his purpose, and that, when once he had made up his mind to do a thing or get a thing, he did it, or got it, somehow. i believe, too, that he meant it as a kind of defiance to me.' 'did he, though!' exclaimed gilbert, as now they sat beneath the awning, at which they had arrived while talking. 'did he! well, he won't get you, anyway, will he? not while i'm alive, anyhow. if, however, i were to die----' but this remark was promptly hushed by bella, who would not allow her lover to even finish it, and, as his watch commenced at six o'clock, he now went below to get an hour or so's rest before that time arrived, while she still sat on beneath the awning, thinking dreamily of him alone and of their future--if any lay before them, which now seemed doubtful, or, at least, very uncertain. then, suddenly, as thus she mused, there happened a thing which startled and amazed her so that she sprang out of her singapore chair and gazed aft, away down towards the south. a thing which even she, a landswoman, a girl originally unacquainted with anything connected with seafaring matters, had, by now, come to recognise and understand as vital to all on board that ship. she had felt the back of the straw hat she wore lifted by a slight warm ripple of air, while, at the same moment, some of the pages of a book she had left lying on the table were suddenly turned over swiftly and with a loud rustle. 'it is the breeze,' she muttered, 'the breeze! the wind at last!' the others on deck had perceived it as quickly as she. at once, those who were about had sprung into action and thrown off the listlessness which had pervaded all in the ship since they had been becalmed. in an instant all was bustle and confusion; the four remaining men who could see rushing about eagerly. the master came out from where he had been talking to some of the sufferers, while charke, running along the waist, called out: 'miss waldron! miss waldron! where is the lieutenant? we want his services now, at once. perhaps he, too, can do as much as any of his own men could if we look alive.' 'i will fetch him directly,' bella cried, full of excitement, and, swiftly, she ran down the companion to the saloon on her way to hammer on gilbert's cabin-door and awaken him. but, as she reached the place she stopped, petrified almost and filled with a vague alarm at she scarcely knew what, while, at the same time, she smothered a shriek which rose to her lips, and exclaimed in its place: 'bertie! bertie! what is the matter?' for she saw him standing by the saloon-table gazing at her, smiling even as he heard her loved voice, yet holding on to the edge with one hand while, with the other, he felt, as it seemed, cautiously before him. and again she cried: 'bertie, what is it? what does it mean?' then she heard his voice saying: 'it means, darling, that i too am struck down. that i too am blind.' chapter xv a light from the past four seamen only left untouched by blindness now, and two officers, to work a ship of six hundred tons! how was it to be, how could it ever be, done? the task was hopeless, and so all recognised on board that unhappy, ill-omened ship, even as now the wind freshened and the bosom of the ocean became flecked with little white spits of foam, while the breeze, hot as the breath of a panting wolf, swept up from the south. a breeze hot now, though once it had been cool--glacial--as it left the icebergs of the antarctic circle. what was to be done? they muttered now, as, together, the six unstricken men took counsel while they stood in the shade of the foredeck awning, and forgot, in their excitement, that one was the master and owner, the other the first officer, and the four remaining ones only poor, ignorant sailors. what! what! what! 'i,' exclaimed pooley, at last, after much discussion, 'can at least steer her. some one must do it if she is to move at all; otherwise, in spite of my seventeen stone, i would be up those ratlins like a boy. but, even then, of what use are five to fist all the canvas she can carry?' 'we can fist some of it, at any rate,' said charke, strong, determined as ever. 'by heaven!' he cried, 'lieutenant bampfyld shall never go back to any of her majesty's ships and say that half-a-dozen men under the red ensign couldn't do something; couldn't make one stroke to save themselves!' then, in an instant, he asked the captain to go to the wheel, while he sent the man, whose trick it was, forward, and, a second later, he was issuing orders to his subordinates. somehow, these orders were obeyed, and in about an hour, during which time all worked with a will and as if their lives depended on it, the _emperor of the moon_ was under close-reefed topsails, foresail and fore-topmast staysail, when, if she had only had her full complement of able-bodied men to do the necessary work, she might well have been under full sail before the still increasing wind, and making a good nine or ten knots an hour. but, now, that was impossible; even if those five could have got all her canvas on her the thing would have been madness. a little further increase of force in the wind, and they would at once have to shorten sail again--which, in the circumstances, it would be almost impossible for them to do--or to stand by and see the masts jumped out or blown overboard. as it was, the _emperor_, under the combined power of the current and what wind they could avail themselves of, was making something like five knots an hour. during all this time bella had been below with gilbert and a prey to terrible anguish, yet endeavouring in every way to cheer and solace him and to thrust her own fears and forebodings into the background. fears and forebodings of she scarcely knew what, yet fears that were, all the same, assuming by degrees a more or less tangible shape. for of late--indeed, long since--there had been intensifying more and more in her mind that feeling of dislike and mistrust of stephen charke which she had experienced from the first moment that she had discovered him to be the second in command of the vessel in which she was to make so long a voyage; for, over and over again, she had remembered, had recalled, how he had said that he was never baulked in the end of what he desired to obtain, and that if he wanted a thing he generally managed to get it. and she knew that he had meant it as a warning, if not a threat; though, certainly, since that miracle had happened which had brought her lover into the very ship which was taking her to india and to him, she had laughed at, had inwardly despised, the threat, if it was one. but now--now! with gilbert stricken down by her side, helpless, crippled by blindness, unable to do aught for himself or her, and with her uncle broken down and worn almost to equal helplessness with his enforced labour and his despair at the ruin which threatened him through the probable destruction of his ship, what--what might not charke do? _he_ was not blind yet, nor---then, as her meditations reached this point, and while gilbert sat by her side on the pretty plush-covered locker with his head on her shoulder, he broke in on those meditations, and what he said could not by any possibility be construed by her as helping to dispel them, but, rather, indeed, to aggravate them. 'at the rate we have been going on,' he said, 'since i came aboard, there will not be a living soul left with their eyesight by the end of the next two or three days. oh, my god! bella, what will it be like when this ship is at the mercy of the ocean, with every person on board blind.' 'don't let us think about it, darling. don't, don't! and even now some may retain their sight. uncle, i, mr. charke, the men----' 'ah,' he said, 'charke; yes, charke. excepting you, dearest, i would sooner charke kept his sight than almost any one else.' 'why?' she asked, thinking that of all who were in the ship she, perhaps, cared less whether charke preserved his sight or not. 'think what a strong, self-confident man he is. even if all the others were blinded and he was not, he would devise something for keeping the vessel afloat, though, of course, he could not work her. he would manage to get us all taken off somehow.' this, the girl acknowledged, not only to him but herself, was true enough. as regarded charke's sailor-like self-confidence, courage and determination, as well as how to do everything best that was necessary in the most sudden emergency, there was nobody on board the ship, nor ever had been, who was superior, or even equal, to him. yet--in sole command and possession of that ship, supposing the other inhabitants of her should also be attacked with blindness and helplessness--what might he not do, if his dogged resolution never to be baulked of anything he had set his mind upon was allowed full sway? her imagination was not a tragic one, nor more romantic than that of most young women who had been brought up as she had been, yet--yet--she shuddered at fears which were almost without actual shape in her thoughts. with all the others blind, herself included; with none to observe what charke did; with the opportunity of removing for ever from his path any who had crossed it--of removing the one whom she felt sure, whom she _divined_, he was anxious to remove; with an open sea around him----'oh, god!' she broke off, while exclaiming to herself, even as her reflections shaped themselves thus, 'never--never will i believe it. never will i think so basely of any man, especially since he has given me no cause to do so. and, as yet, there are plenty left with their eyesight; plenty to see what is going on.' her uncle and aunt came into the saloon now, full of a distress that was visibly marked upon both their faces as well as their demeanour, yet both as kindly as ever in their manner, and uttering expressions of sympathy with gilbert in his affliction. but, all the same, bella could not but observe the look of absolute illness and grief on captain pooley's countenance, nor help trembling inwardly at the fear that he might be the next one attacked. nevertheless, he said cheerfully enough, after he had exhausted his condolences with the young man: 'we are doing some good now, at any rate. the "cherub" is marking about six knots; if the wind keeps where and as it is we may yet fetch mahe, or one of the other seychelles. in fact, we must reach them, or some other place, or----' 'or what?' asked bella, looking at him with tear-laden eyes. 'or,' her uncle said, not, however, concluding his speech as he had originally meant to do, 'or drift about until we fall in with another vessel. we ought to do that, too,' he continued, 'for we are almost in the direct track from the red sea to australia; we are in the track of the big liners.' 'how,' asked gilbert now, while forcing a smile to his face as he spoke, although it was but a poor, wan substitute for the bright, joyous one that generally lit up his countenance--and, indeed, it was only assumed with the hope of cheering his sweetheart by his side, wherefore, like all other substitutes for the real thing, it was but a wretched copy--'how are my brother-sufferers? it would be cheering news to hear that some of them were regaining their sight.' 'at present,' pooley replied, 'only one of your "fellow-sufferers" seems to be doing so, and that's not a human being but no other than bella's _protégé_ the tiger-cub. that creature is, we all believe, coming round. it is rambling about the deck by itself, but it undoubtedly can see now to avoid hitting its head against the raffle lying there. however,' he went on, 'here's a little information which you may both be glad of, upon which he dropped his hand into his nankeen jacket and produced from it an old, dirty, and much-thumbed book, on which, in addition to many other unclean marks and stains, were added droppings from candles.' it was evidently, as bella at once divined, one which had been pored over at night; while, had she been well acquainted with the habits of those who dwelt in the forecastle, she would have also understood that mercantile jack is often in the habit of sticking lighted bits of candle about whenever he wants to read, and even to the sides of his bunk in which he lies, when he sleeps in one instead of in a hammock. 'millett,' her uncle went on, naming one of the men who had still retained his eyesight, 'showed me this an hour ago. it belongs to poor wilks, and is a book entitled _calamities of sailors_, it being a collection of odds and ends accumulated from various writers by an unknown hand. now, here,' he went on, 'is a strange account of blindness attacking a vessel in much the same way as those in my poor old _emperor_ have been attacked, and----' 'did they regain their sight?' exclaimed his listeners together; all three, namely, mrs. pooley, gilbert, and bella, asking the same question in almost the same words. 'they did,' the master went on, 'in this case. it happened on board the _james simpson_, in 1803. but in another, i am sorry to say, they did not; and also, i am sorry to say, this is a very circumstantial account, given by m. benjamin constant to the french chamber of deputies, in 1820, when he was speaking on the horrors of the west african slave trade. he tells how a french ship, _le rôdeur_, having a crew of twenty-two men and a hundred and sixty slaves, left bonny in 1819, and was attacked with almost precisely the same blindness which has now fallen on most of us. things were worse with them than in this ship, however. they had scarcely any water, the air below was horribly impure, and, when the poor wretched slaves were allowed on deck, they locked themselves in each other's arms and leaped overboard in their agony, so that the french captain ordered some of them to be shot as a warning.' 'yet,' exclaimed gilbert, '_le rôdeur_ must have got safely into harbour at last, or m. constant would not have given his information.' 'yes,' said pooley, 'that of course is so. pray god we do, too'; whereon he closed the book and dropped it into his pocket. it was well he should do so. well, too, that bella did not ask to be allowed to read it for herself, for it contained a good deal more than her uncle had thought fit to read out, and described further horrors which it was not advisable that any in that saloon should be made acquainted with.[1] chapter xvi man overboard another day had passed and the south wind still blew gently, neither increasing nor decreasing in force, so that the log showed that the _emperor of the moon_ had progressed between a hundred and fifty and two hundred miles farther north. farther north, as all said now, but not to bombay, since they had abandoned all hope of reaching that port in their present short-handed condition, and without obtaining fresh assistance--but towards the seychelles. that was the harbour of refuge to which their thoughts and aspirations pointed at this time; the spot where, even though they should obtain nothing else, they would at least be in safety, and the one from which they could be taken off by some other ship if they were not able to find the means of working their own. but, even as this day was drawing towards its conclusion--a day hotter, it seemed to all on board, than any they had previously experienced, and when neither the awnings nor the breeze that came aft protected them sufficiently to allow of their being on deck, unless duty demanded that they should be there--a change was perceived to have taken place in the condition of one or two who had been attacked by blindness. mr. fagg had declared that he was regaining his sight, and that, although he could not distinguish small objects with any amount of clearness, he was nevertheless able to see large things, such as the form of a man or woman, in a blurred, indistinct manner if he or she happened to enter his cabin; while wilks averred that his sight was also returning rapidly to him. 'for, see here, sir,' he said to charke, who, learning what was happening, or said to be happening, had gone forward to question him on the subject, 'i can walk aft to the break of the poop without stumbling against anything or over anything either. may i show you, sir?' 'ay,' replied charke. 'show me. let's see what you can really do,' while at the same time he motioned to a sailor, who happened to be by the mizzen-mast, to throw down gently a coil of rope he held in his hand so that, when wilks neared the spot where it was, they would be able to observe whether he could see clearly enough to avoid it or not. meanwhile, wilks, having received the necessary permission, had started from close by the fife-rail, where the conversation had been going on, and was making it perfectly clear that what he had stated was undoubtedly the truth. for, independently of the coil which the sailor had deposited abreast of the mizzen-mast, there was at this moment a good deal of raffle lying about the deck, as well as a bucket or so, and also a squeegee alongside the saloon skylight. but wilks saw them all and steered himself along, avoiding each and every object both great and small, while, when he approached the coil of cable, he passed round it in almost precisely the same manner that a man in possession of his ordinary eyesight would have done. then he looked back--at least he turned his face back--towards where he had started from, and, with a gratified grin on his countenance, asked charke if he was not all right. 'yes,' replied charke, 'or getting so. if one or two more of your mates would only recover in the same way, we might bend another sail and, so, make a few more knots. yet, curse it!' he muttered to himself, 'as one gets well another gets ill.' this was unhappily only too true, for not an hour before he had been called to observe that wilks seemed to be on a fair way towards recovery, he had learnt that pooley was, although not stricken with the blindness, yet rapidly becoming blind. he had himself discovered such to be the case when, after lying down for an hour, he had been unable to perceive anything clearly on awakening. and, in another hour after this had been found by him to be the case, he was obliged to acknowledge his darkness of vision was becoming more intense, and that he feared his sight would be entirely gone by nightfall. this was, perhaps, the greatest blow of all to several on board the unfortunate ship; on bella it fell with overwhelming force. for now she recognised that, of all others, the very man she most feared and dreaded--though she could not have explained why that dread should have taken possession of her--was in absolute control over the ship, and could indeed do what he liked with it. her uncle, she understood, could of course still issue orders, but--how was it to be known that those orders were being obeyed? then, strong-minded as she was, and feeling more so, as well as more self-possessed because of the presence of her lover in the ship, she again forced herself to discard such miserable and--as she termed them in her own mind--ridiculous fears, and set herself about the task which had now for some time developed on her of attending to the catering of the ship and looking after the sufferers generally. for, from mrs. pooley, bella had not at any time received much assistance, owing to the fact of the poor lady having been quite ill since the calamities on board began to follow each other in such frequent succession, while, now that her husband was struck down, she appeared to have collapsed altogether. indeed, at this present time, she was doing nothing except lying on the plush-covered sofa of the saloon, while moaning feebly that they were all doomed, and that, even if the ship was not utterly cast away and lost, there would soon not be a living soul on board who would be able to see. 'and then,' she sobbed, 'what can happen to a vessel--in the night, especially--full of men and women who are all blind and cannot find their way from one end of the deck to another?' 'nonsense, aunty, dear, nonsense!' bella replied, while endeavouring bravely to dispel her aunt's forebodings, which, in solemn truth, she shared to the full with her, though not for worlds would she acknowledge that she did so. 'are not some already getting well--mr. fagg, and the sailor, wilks, and bengalee----' 'while at the same time others succumb to the blindness,' mrs. pooley interjected, still with a moan. 'and now your poor uncle, of all others.' 'well,' said bella, still stout of heart, 'we have this comfort: it soon passes away. let me see. bengalee has been blind about a fortnight, wilks and mr. fagg about twelve days--whatever is that noise!' she exclaimed, breaking off suddenly. as she uttered that exclamation there had come a sudden racket above their heads, the noise descending through the wide-open skylight. a noise which seemed first like the yelp of a dog in pain; then another which resembled somewhat the spitting of a cat, followed by a shrieking kind of growl, and then the voice of charke exclaiming angrily: 'i'll have the infernal thing thrown overboard. here you, catch hold of it--make a loop and fling it over its neck. catch it, one of you!' 'oh!' cried bella, forgetting everything else for the moment, and rushing towards the companion, 'it's bengalee!' then she swiftly ran up to the deck, and saw the tiger-cub standing close up by the frame of the skylight and growling at charke, whom it regarded with terribly vicious eyes. and she noticed, too, that it held up one of its hind legs as though it were injured. 'what are you doing to the creature?' she cried. 'you have been kicking it again, you----' she was going to say 'brute,' but restrained herself. 'and you shall not have it thrown overboard, as i heard you order the men to do!' she continued. then she went towards the creature perfectly fearlessly, and spoke to it, and eventually stroked its back, so that at last its growls subsided altogether. the chief mate's face had presented an appearance of scowling rage as she reached the deck, while it had on it an expression that boded ill for any extended existence being accorded to bengalee had she not appeared at the moment she did. yet, by the time she had ceased petting the animal he had managed to control himself considerably, and to smooth out the look of temper from his countenance. and now he said: 'oh, of course i did not really mean to do that, miss waldron. though it will have to be got rid of eventually. it is impossible that it can be kept much longer. and, you know, we have enough work to do without attending to such an animal as this. just think! i am the only officer fit for duty, and i have only four able men to work with--since wilks cannot be called well yet.' honestly, bella felt sorry that she had spoken as hotly as she had done, since she did indeed recognise the almost superhuman amount of work that had fallen on charke's shoulders just now. he seemed never to sleep but was on deck night and day, sometimes steering, sometimes even going aloft alone, and hardly ever snatching a quarter of an hour for his hasty meals. she murmured, therefore, some words of regret, and was going on to say how sorry she was for having been excited, when he stopped her. 'no, no, miss waldron. it was nothing--nothing. the thing did spring at me angrily as i passed where it was sleeping, and i kicked it. i am sorry, too. and you know i would not injure anything you liked,' while, as he spoke, he bent his dark, handsome eyes on her. perhaps it was a pity he uttered these last words, since in her own heart she did not believe that they were true. she had seen his glances more than once directed at gilbert when he had not known that she was observing him, and she thoroughly believed that, in them, there was a malignant look, a look of hatred, which belied his words. and she had seen--she _thought_ she had seen--something else in those glances when gilbert was first attacked with blindness which, if not gloating, was very like it. she said, therefore, now, as she turned towards the ladder: 'then you won't punish it, mr. charke, will you? you won't let it be thrown overboard in any circumstances, will you?' 'it shall be as sacred to me as you are,' he replied. 'its life as sacred as yours.' but all the same, she told herself as she went back to the saloon, that, if there was anything charke hated in that ship, or rather, any two things he hated more than all else, those things were her lover and bengalee. presently, not ten minutes later, she again heard his voice, calling out loudly to one of the men this time: 'if we could only get another on her we could make two more knots, i believe. if only some of those who are blind but not otherwise incapacitated would help on the braces and get the yards round, we could do it.' she was not the only person who heard these words. not a moment had they left his lips before the curtains in front of gilbert's and mr. fagg's cabins were pushed swiftly back with a metallic jangle, as the rings ran along the rod, and each of the young men appeared in the saloon and began making his way guided by his hands, towards the stairs leading up to the deck. 'oh!' cried bella, not quite understanding what it was charke wanted done, or what assistance could be rendered by persons who were blind, 'what are you going to do? gilbert, don't do anything rash! nor you, mr. fagg!' though she saw by their faces and the smile that came to each that she had overrated any harm that was possible. 'we'll get that sail on,' exclaimed gilbert, as he felt his way up the stairs, and fagg said: 'we will so,' as he followed him after they had each jostled the other at the foot in a slight collision which their sightlessness had caused, and, a moment afterwards, bella and mrs. pooley were left alone in the cabin. yet they could hear, plainly enough, the words of approval bestowed on gilbert and fagg for their promptness, when the meaning of it was recognised by those on deck; and they caught, too, the orders bawled with great rapidity by charke the instant he had received this extra assistance. also, they heard him ordering one man to the starboard main braces and another to go forward and loose the jib. a moment later they heard something else as well. the cry of two or three voices together, the roar of charke, and then his trumpet-tones, exclaiming: 'my god! he's overboard!' and bella, with the image of one man alone in her mind, reeled backwards towards the sofa where mrs. pooley lay, and gradually slid, fainting, on to the cabin floor by her side. chapter xvii 'farewell, my rival' had bella known more about a ship and its intricacies she would have understood that, notwithstanding some one had undoubtedly gone overboard, the sailor, whoever he was, could not by any possibility have been one of those who had gone to help in squaring the yards. instead, she would have been aware that such an accident could only have happened to some seaman who had either gone aloft or out on to the jib-boom. and, in fact, the latter was the case; the unfortunate fellow, a man named brown, falling off the boom while endeavouring to set the flying jib, and being struck a moment later by the frame timbers forward as he fell. yet the unhappy sailor seemed still to have some life left in him, as those who rushed to the port side could see, since, as he was passed by the ship, he was observed to rise to the surface--his head all shiny with blood--and to strike out manfully. but what could that avail, since, by the time the _emperor_ could be brought to the wind and a life-buoy thrown overboard, he was half a mile astern? to lower the boats in time to save him would also have been an impossibility, even if it could have been done at all; and, moreover, the swift-coming instantaneous darkness of the equator was at hand, so that the man himself was, by now, almost invisible. 'steer her course again,' charke called out, therefore, to the man who was at the wheel, in a voice in which regret for the unfortunate sailor was mingled with a tone denoting some other sentiment that, perhaps, none would have been able to understand, even though they had been swift to observe it, as, in their excitement, none were. then, at once, in a few moments, the _emperor of the moon_ was again heading towards where the seychelles lay. what was that other sentiment which now pervaded the breast of this strong, masterful sailor; this man who had worked untiringly for hour after hour on stretch, and who seemed to rise triumphant over nature's command that both sleep and meals should be properly partaken of? the man who had not changed his clothes for three days, nor even had them off his back when he sought a quarter of an hour's rest here or ten minutes there? what was this sentiment? nothing but a certainty that this was the last voyage the ship was ever to make--a feeling of intense conviction, which had been growing upon him for some time, that all in the ship were doomed. for he, at least, could see--_he_ was not blind yet--and, more than all else on board, perhaps, could feel; and his sight showed him things over the water, in the density of the atmosphere, even in the appearance of the brassy heavens above, which told him that, ere long, the slight whispering breeze which blew would be changed into a hurricane howling across the ocean. his feelings, his nerves, the moisture of his skin corroborated, also, what his sight proclaimed. 'it will come,' he muttered to himself, as now he paced the after-deck, with his eyes never off the light sail that the ship was carrying. 'it will come soon, and then we are done for, even though i get every inch of canvas off her first. this man's death leaves me and three other sailors as the only persons to work the ship. it is strange if, even under bare poles, we continue to swim.' then, as he turned his head towards where bella (who had soon recovered from her faintness) was now standing talking with her uncle and her lover, he muttered another sentence to himself--a sentence which, should a romancist or a dramatist inspire one of his characters with it, would, perhaps, be deemed unnatural, yet which this man of iron will and fierce determination muttered to himself as calmly as he would have given an order to one of his few remaining sailors. 'if it blows, as i believe it will, twenty-four hours will see the end of us all. she--oh, my god! she will be dead--but so will he and so shall i. well, there's consolation in that. if i can't have her, no more can he. that thought makes the end mighty cheap.' here he strode towards those three standing by the break of the poop, and touching his cap to bella--he was, as she had observed, a gentleman, and in all that became the outward semblance of a gentleman he never failed--he said quietly to the poor, blind captain standing by her side with his fingers resting lightly on her arm: 'we must get in all the sail, sir, now. there is a change coming; i know it--feel it. the glass, too, stands very low, and since we cannot work the ship in a storm, short-handed as we are, we had better commence at once. it will be pitch dark in ten minutes and there is no moon.' 'good god!' exclaimed pooley, 'what is to happen next? the glass low, you say? well, that means a change of some sort, though not necessarily bad weather. what are these feelings you speak of, charke?' 'the feelings of a sailor,' he replied. 'you know them as well as i do. ha!' he exclaimed, 'there's lightning in the south. no time to be lost.' then he seized the boatswain's whistle, which he had hung round his neck and used since the man himself had become disabled, and blew it as a signal to his three remaining hands to be ready for his orders. 'now then,' he cried, 'up with you and stow the few sails that there are. what do you say?'--to one who muttered something--'tired--been working all day? why, damn you! haven't i been working too.' charke rarely swore, but he was impelled to do so now, especially as he had moved out of bella's hearing. 'do you see that lightning down there in the south? do you want the ship to be blown over and go to the bottom in her? here, you stop at the wheel,' addressing the man who was already at it, 'we others can do it somehow. follow me'; and away he went to the topsail yard, selecting the most arduous part of the business for himself. while he muttered to himself as he did so: 'now, if i should go, too--fall off the yard--they are doomed beyond all help. nothing then can save him.' which thought caused a strange, weird kind of smile to be on his face as he sprang up the ratlins. and, stirred to action by his own indomitable energy, the men did set about the work and managed it somehow, the sails being stowed in a very unshipshape fashion (or what would have been an unshipshape fashion if the proper quantity of sailors had been there to do the job) and in such a manner that the first gust of the coming tempest would be as likely as not to blow them clean off their lashings. still, it was done at last, and not too soon either, since, ere they had concluded their work, the lightning was flashing incessantly and huge drops of rain were falling. 'it's a south-easterly wind,' said gilbert to bella, turning his cheek towards it. 'where will it blow us to now?' charke thought he knew, as he listened to the remarks, since he had returned to their vicinity after coming down from the topsail-yard, but he uttered never a word. even now he loved the girl by their side too much to frighten her more than was necessary. yet, had he said that he knew that, short of a miracle, it must be the bottom of the ocean--as was the case--she would probably not have heard him, since, at this moment, with a devilish shriek, the gale was upon them. upon them and almost pooping the ship as it struck her right aft, and then driving her forward in the churned sea with a horrible, sickening motion, while, since she was fairly deeply laden, she recovered herself from the avalanche of water but slowly. an avalanche that, sweeping over the poop with a roar and a swish, took bella and gilbert off their feet and hurled them forward staggering, and buffeted against each other. 'below--go below, all of you!' roared charke to them, and also to pooley, who had himself been sent sliding along the deck and was now hanging on to a belaying-pin, even as he called out to know where bella was. 'below, i say! we must close the hatches, or she will have the sea in her. below, quick!' and, rushing towards bella, he led her to the after-companion, dragging gilbert with his other hand and returning for pooley. and now the tropical lightning--that violet-hued lightning which is so beautiful and also so sure a sign of awful turbulence in the elements--played incessantly on the ill-starred _emperor of the moon_; the seas were mountains at one moment, valleys at another. the ship, too, was rolling so that it seemed as if everything on her deck must be pitched off her into the sea--as was indeed the case with many of the smaller things which went to form the raffle lying all about--and each time that she went over to port or starboard she took tons of water over her side. then, a still more gigantic wave caught her on her port-bow, and absolutely threw her up, it rolling directly afterwards under her counter and letting her drop directly afterwards into the trough, while over her poop, again, came that which seemed to be not a wave but the whole indian ocean itself. amidst it all charke still stood at the wheel, holding on to it as perhaps few solitary men had ever held on to a wheel in such a sea before; his arms actually bars of iron, yet appearing to him as though deprived of all sense and feeling. he stood there silent, determined, resolved, awaiting death, knowing that it must come and not dismayed--because it must come to that other, too, that man below in the saloon who loved and was beloved by bella. then, suddenly, he knew that he was not to die there alone at his post while his rival expired in his sweetheart's arms, or she in his; he knew--he discovered that not to him alone was to belong all the bravery and the resolution. creeping up from below, thanking god that the hatch had not yet been closed, feeling his way by his hands and gradually reaching the wheel--buffeted here and there; knocked down once, then up again--gilbert bampfyld crept to his side, and, an instant later, was fingering and, next, gripping the spokes. 'let me help you!' he roared, so as to be heard, while feeling as he did so which way the other man who already had hold of the wheel was exerting his force. 'blind as i am, i can do that. who are you?' 'stephen charke,' the other answered, also shrieking his name. 'help, if you like. but it is useless. we are going.' 'i know it,' gilbert answered. 'well! we will go down standing.' and charke, still endeavouring to hold up the ship, still to protract life from one moment to another, muttering inwardly: 'curse him! he is a man. one worthy of her.' then, unceasingly, he continued his work, wrenching, striving, endeavouring in every way to save the ship from being pooped or flung over as the waves took her and cast her up like a ball, or hurled her down like a falling house into the gaping, hellish troughs that lay below, yawning for their victim. but still the lightning played upon the doomed craft, illuminating her from stem to stern, showing the fore top-gallant mast gone and the jib-boom carried away, broken off short, three feet from the bowsprit head. also it showed something else--something that, had he had time to think of aught but preventing the ship from falling off the course he was endeavouring to steer, might have struck a feeling of wild horror to his uncanny breast. for some of the blind, stricken men forward had crept by now out of the forecastle and other places where they had herded, and were crawling about the foredeck, holding on to whatever they could clutch--belaying-pins, the fife-rail, the racks, even the ring-bolts. amongst them, too, was the tiger-cub, an almost unrecognisable lump, except for the topaz gleam which his eyes emitted: a gleam that, as a sea, which was in truth a cataract, washed it from the foremast almost to where he stood, appeared to charke malignant, devilish, threatening. and he heard those unhappy men's voices, cursing, blaspheming, praying: roaring that they feared no death which they could see, but that they wanted to go neither to heaven nor hell enveloped in utter darkness. 'no jack who ever sailed,' they screamed, 'feared a death that he could face, but we fear this. and if we had but our sight, maybe there'd be no death at all!' 'ay, but there would, though,' muttered charke to himself--'there would. ha! by god, look there,' he cried aloud, forgetting that the only man who could hear his words was blind. the ship had given another hideous plunge--had wrenched herself as a giant might give a wrench in endeavouring to free himself from the chains that bound him--then down! down! down! she went into the hollows of the ocean, so that up above her on either side were nothing but vast walls of sea. walls that would, that must close together, charke understood, fifty feet above their heads, leaving the ship beneath them. and then he turned to the other man by his side, saying calmly: 'now is the time! you love bella waldron. so do i. and neither of us will ever set eyes on her again. farewell--my rival!' chapter xviii 'she will never know' 'how in heaven's name has she ever done it?' muttered charke to himself, three minutes later, as, dripping like a dog dragged out of a pond, he still stood by the wheel while holding on like a vice to the spokes. and still both he and gilbert had each got their legs twisted in the radii to prevent them from slipping, since now the ship lay over frightfully to starboard and did not recover herself at all. 'ah, well,' he continued, 'it does not matter much how. another five minutes and over she goes--turtle. it is a hundred to one she has six feet of water below.' how had she done it? that was the wonder, the marvel; the more especially a wonder if, as charke thought, she had six feet of water in her, since twice that amount would have taken her to the bottom even though she lay in the most tranquil waters of the universe. it was impossible she would have risen again, if overloaded thus. yet, water in her or not, she had accomplished a marvellous feat for any craft that ever left the shipbuilder's yard. for, from down below in those awful depths, with, on either side of her, and glistening all around her in the glare of the lightning like the sides of a crevasse, those walls of sea, she had still risen above them and had (a moment or so after they seemed to be closing in on her and shutting her out for ever from the world above) been once more poised on the crest of a huge billow. she had done it, and now lay listing over on to her starboard side, as some great wounded creature might do whose right ribs had all been broken in by the blows of a pole-axe. but still she travelled through the water in the darkness of the night; for now the lightning was ceasing and, also, she carried no lighted lantern since there were none to attend to such things--while, even though there had been, the beating of the gale would soon have extinguished them. she travelled swiftly, too, cutting her way through billow and wave, taking in huge seas aft which swept her decks--yet going still. but with some of those spectral forms, those blind groping men, departed for ever; swept down the sloping deck by tons of water, down and over into the ocean. and of the few, the three who had still their sight, one lay with a broken neck at the foot of the foredeck companion-way, having been flung down the hatch-way head foremost; the other two were drunk. they had broken into the steward's room, where there were none to control them, and had found some bottles of beer, as well as one of brandy and one of rum--and this was the result! at that moment the wheel spun round in gilbert's hands, dragging him with it in its revolution, so that he thought he would have to let go or be thrown in a somersault over into the sea; then, as he forced it back, he heard charke's voice bellowing at him: 'can you hold her up for five minutes? i can grasp the spokes no more; i am done. i would not have let go like that, god knows i wouldn't, but i have lost all sensation in my arms and hands. i will lead fagg out. perhaps he can help.' 'i may hold her steady,' gilbert answered, 'but no more. what can a blind, stricken man do?' 'it is enough,' charke said. 'sight would not aid you to do more, and, after all, it is of no use. we but prolong life for nothing. yet, here goes.' he made his way below, falling, sliding down the companion-ladder, tumbling along in the darkness to where he judged the door of fagg's cabin was; he fell over things that had been hurled out of the steward's pantry on the port side--broken dishes, plates, tin utensils, potatoes peeled ready for cooking, and a joint of meat--he felt all these with his feet and benumbed hands, and found a bottle, too, which his smell told him was rum. then he tore the cork out of it with his teeth and drained a tumblerful of the raw spirits. that gave him fresh life and energy; the blood coursed and danced through his veins again, his fingers began to feel, his arms to strengthen. sliding back the door of fagg's cabin he called him by name, and, receiving no answer, felt in the berth to see if he was there, while, even as he discovered that the bed was empty, he trod on an upturned face, and then stooped down and felt it and the head, and found the latter all broken. whereby he understood what had happened to the unfortunate young officer, and knew that he had either been hurled out of his bed against a bulkhead, or, being out of it, had been dashed to death. he would have gone back now to relieve gilbert, and was turning to do so when his eye caught the glimmer of a light down the narrow gangway leading to the saloon, and he knew at once that somehow those within had managed to get the bracket-lamp over the table lit. whereon he went towards that saloon, intent on seeing how those who were in it--especially _one_ in it--were preparing to meet their end. were they bearing up bravely? was she--was that girl who maddened him, that girl, through his unrequited love for whom, he knew, he felt, that all his better qualities had been driven out of him--preparing to meet her death nobly, valiantly? the sight he saw might have struck horror to a bolder, a better man than he. a sight more fitting to meet the eyes of one who gazed into a catacomb or charnel-house than into what had been, not long before, a pretty, bright saloon. mrs. pooley lay flat upon her back, moaning feebly, her stout body rolling backwards and forwards with every swing of the ship and every plunge it made. the captain was on his face, and above him lay half the debris of the shattered, sea-wrecked cabin. but bella! she frightened, startled him! 'the others may be dead,' he whispered, 'but she, surely she is alive. god! how her eyes stare, yet--yet how lovely she is still.' the girl was sitting upright upon the saloon sofa, her hands gripping the head of it as though, all unconscious as she appeared to be, she still knew that she must do that to save herself from being flung down, and her lips moved faintly. then he wrenched the bottle of rum from out of his pocket, he having put it there with a view to administering some to gilbert when he regained the deck, rival though he was, and moistened her lips with it. 'miss waldron--bella,' he whispered, allowing himself in those last moments the luxury of calling her by the name that he had whispered so often softly to himself. 'bella! for god's sake, say something. tell me that you are not dying.' and she did whisper something--a word that he heard above all the roar of the hurricane thundering aloft, above the awful concussions of the ship's sides as again and again the tons of water struck at her, heavily, savagely, and as, also, she struck at them in her maimed progress; above even the rattle of ship's furniture rolling about, and the sickening thumps of the unlashed piano as it beat against the stem of the mizzen-mast. she whispered a word or so. 'gilbert,' those white, cold lips muttered; 'gilbert, my darling, we are dying together. clasp me to your arms now. hold me in them to the end.' with a moan, not a curse!--a curse would not have availed or eased him now--he started back in that dim cabin, hurling the bottle from him as he did so. his rival! his rival! again, even now! his name the last word on her lips, his image the last thing present to her in the hour of death. then he fled from the cabin back again to his post, back to the wheel to which he swore he would lash himself, and so go down thinking of nothing but his duty. there was, his fevered mind told him, nothing but that--but his duty--left. as he went along he noticed, distraught though he was, that the vessel was making a kind of rotatory movement under him; that she seemed, indeed, to be gliding round and round in a circle although beaten back more than once by the awful force beneath her. 'he has left the wheel!' he cried, his swift and accurate seaman's knowledge and intelligence telling him at once what had happened. 'is he mad--or dead?' and clutching, grasping at everything that offered a hold to him, he forced himself back to where the wheel stood, only to find when there that gilbert was lying senseless by it. senseless but not dead, as one thrust of charke's hand under the other's wet clothes, towards the region of the heart, told him very well. an instant later he had resumed his hold on the spokes, and was endeavouring to put the ship on her course before the howling winds, to keep her straight on into the dark, impenetrable depth of blackness ahead of her. again the marvel was that she did not go over, or did not suddenly sink beneath the weight of water that was pouring in on all sides--sink like a stone. and he began to tell himself now that, as she had borne up so long, as the storm could, by no possibility, become worse and must, at last, abate, there was still a hope. a hope of what? that he and bella might both be saved; be saved, and saved alone, together. 'she is alive and i am alive. the others are dead, or dying. oh, god! if she and i are spared----' but that sentence was never finished! for, as he partly uttered it there came an awful crash, a crash that hurled him back, then flung him over and over on the poop--a grinding, horrible concussion, followed by the most terrible thumps and by the sudden cessation of the ship's passage. and, a moment later, the vessel heeled over, though still beating and thumping heavily, so that now the water poured into her forwards, and, gradually, her fore-part was entirely immersed. but still the pounding and the awful grating continued, while growing worse and worse. 'she has struck,' he muttered to himself. 'struck on a reef or a rock. the end has truly come.' in a moment he had picked himself up from the poop-deck, and, difficult as it was to move with the vessel beating backwards and forwards, had dragged himself down to the saloon--down to where bella was, the woman whom he would save or die with. the lamp had gone out with the concussion. all was in darkness, and, above the roar of the tempest outside, he could hear the furniture beating about the saloon as the ship swayed and wrenched. yet he went on towards where he had left her ten minutes before; on towards the sofa on which she had been sitting almost unconscious. she was not there he found, but, instead, lying insensible at the foot of the sofa. insensible, he knew, because, to his words, his summons, she returned no answer. then, in a moment, he had seized her in his arms, had lifted her up, and, with her head upon his shoulder, was groping his way with unsteady, stumbling feet towards the gangway. her head upon his shoulder now, her hair brushing his face now, in this moment, in the hour of destruction--for one, for both of them! her head upon his shoulder! and he a mortal man! it was beyond endurance; more than he could bear! acknowledging this, recognising it, he slightly moved, with the hand which was around those shoulders, that face so close to him, that face so close, so cold and chill--and kissed her long and passionately. 'she will never know,' he muttered, 'never know. yet--yet it has made death sweeter. death! the death that will be ours ere many more moments have passed.' yet, near as that death was, so near as to be beyond all doubt, as much beyond all doubt as that the rocking, shivering ship was breaking up fast, he felt his way towards where he knew the life-buoys were, and rapidly fitted one on to each of them; while, as he did so, he murmured again and again: 'if any are saved it can only be she and i. yet even of that there is no hope.' chapter xix 'i almost dreaded this man once' the indian ocean lay beneath the purple-scarlet rays of the setting sun as calmly and as peacefully as though, across its treacherous bosom, nothing more violent than a cat's-paw had ever swept. indeed, so calm and peaceful was the spaceless sheet of cobalt that, almost, one might have thought he gazed upon some quiet tarn, or inland lake, shut in and warded off from any breeze that might blow or any tempest that could ever roar. only--he who should stand upon the pebbly beach of a little island upon whose white stones the surf hissed gently as it receded slowly and faintly--as though it were asleep and languid--would have known that, for thousands of miles ahead of him, there was nothing to oppose the tempests of the east and south, or prevent them from lashing that now calm and placid ocean into madness, or from exerting their powers of awful destruction. a little island set in that glittering, sapphire sea, with, all around its circumference of five miles, a belt of white bleached stone and sand, and with, inland and running up from the belt, green grassy slopes, in which grew tall palm trees, vast bushes or tufts of bananas, orange and lemon trees, mangoes and yams. there, too, were grassy dells through which limpid streams of pure cool water ran until they mingled with the salt ocean; there the wild turtle-dove cooed from guava and tamarind tree, the quails and guinea-fowls ran about upon the white silvery sands; while, to complete all these natural advantages, neither mosquito nor sandfly existed. a little island girt by coral reefs--the ocean's teeth, strong, fierce, and jagged; teeth that can rip the copper sheathing off a belated vessel as easily as a man can rip the skin from off the island's pink and golden bananas; teeth that can thrust themselves a dozen or twenty feet into the bowels of forlorn and castaway barks and tear them all to pieces as the tusk of the 'must' elephant tears the bowels of its victims. a little island, one of a thousand in that sometimes smiling, sometimes devilish, sea--such as are in the chagos archipelago, or the seychelles, or the cormoras, and, like so many of those islands, untrod, unvisited by man. unvisited because, where all are equally and bounteously supplied by nature, there is no need for any ship to draw near this solitary speck that is guarded from all approach by those belts of coral, and also because, to this small island, there is no natural harbour should rough winds blow. now--as still the setting sun went swiftly down amidst its regal panoply of purple and violet and crimson, while, above those hues, its rays shot forth great fleaks and flames of amber gold--it was not uninhabited, not desolate of all human life. upon a grassy slope a man lay, his head bound up with linen bands; one of his hands being swathed, too, in similar wrappings. and his eyes were closed as though he were sleeping--or dead. to her who gazed on him it seemed almost as if it must be the latter--the greater, the more everlasting sleep, that had fallen on him. for there were two in this island now; she who thus looked down on the prostrate man being a woman clad in a long dress, which once had been of a soft, delicate white fabric, but, now, was stained and smeared with many splashes and marks, and was rough and crumpled with hard usage and by the effects of seawater. her hair, too, was all dishevelled, uncombed and unbrushed; tossed up in a great mass upon her head; bound with a piece of ordinary tape. and still she was as beautiful as she had ever been; beautiful in this negligence which was the result of shipwreck and of battling with tempest, of cruel buffetings from merciless waves and jagged rocks--beautiful, though on her face and in her eyes was now the sombre beauty of a despair and misery too deep for words. for he whom she loved, he whose wife she was to have been, was not upon that island with them, and had no more been heard of since, in the arms of stephen charke, she had been plunged into the sea and, in those arms, borne to safety and to life. she gazed down on him now, in the last glimmering beams of the golden light that shot athwart the island, while regarding him with some expression in her glance which caused that glance to be not altogether a reflex of her own misery and despair. an expression that seemed to denote a supreme pity, an almost divine regret for him who lay before, and beneath, her, in pain and suffering. 'how brave--how strong he was!' she murmured inwardly, her lips not moving. 'how he fought with that storm--fought with death to save me and himself! no!' she broke off, still uttering her meditations to her own heart alone--'why do him such injustice even in my thoughts? it was not to save us both, but me alone. there was but one desire in his soul--to save me!' she turned and went to a small heap of fruit that she had gathered earlier in the day, and selected one of the great pink bananas--pink with a lustrous beauty which those who only see them when they arrive in northern climes could never believe they have once possessed--then she took a scooped-out cocoanut shell, and, going to a little babbling rill that ran through the grassy defile, filled it with water. after which she returned to where the other lay, and, kneeling by his side, gazed on him again. 'my god!' she whispered. 'i almost dreaded him once. feared him for i knew not what. feared him! him! and he has been my saviour.' he seemed to know that she was by his side and near him; for, even as she murmured these words to herself, stephen charke opened his eyes--a faint smile appearing in them--and gazed into hers. 'you are better?' she asked, as she gave him the shell with the water in it, which he was not too weak to be able to take and raise to his lips, while she tore off the rind of the banana. 'your forehead,' she went on, while putting her hand upon it calmly, as a sister might, 'is cooler. are you still in pain?' 'no,' he answered. 'no--only very weak. are--are--any more saved from that?' and he directed his glance to where, two hundred yards off from the island, lay something protruding above the water which looked like the rounded back of a whale, but was, in truth, the torn and lacerated keel of the _emperor of the moon_. in her last struggles--in her last convulsions as the gale had hurled her on to the coral reef--she had turned almost completely over. 'no,' she replied, her face an awful picture of despair and anguish. 'none are saved but you and i. oh!' and she buried that face in her hands and wept aloud, piteously, heartbrokenly. 'god rest their souls,' he said solemnly. 'god pity them! why i, too, should have been spared except to save you, i do not know. i might as well have gone down with them.' 'no! no!' she cried. 'no, mr. charke. you must be spared for better days, for greater things. oh,' she exclaimed, 'how bravely you battled with it all! uncle told us,' she went on through her tears, 'when we were below and before i became insensible, that your efforts were superhuman; that, if the ship could be saved, it would be by you alone. and,' she continued, 'how you saved me i do not know. only--only--i wish i had gone with him, with gilbert.' 'nay,' he said--'nay. do not say that. and--and--i ask you to believe that, had it been possible, i would have saved him too. but it was impossible. impossible to so much as slip a life-buoy over his shoulders. the end was at hand, the ship broken in half. it was impossible,' he repeated earnestly. 'how,' she asked, as she sat by his side gazing out across the calm, waveless sea through the fast-coming tropic night, and watching the great stars--almost as big as northern moons---sparkling, incandescent like, in the blue heavens above--'how did you do it? i remember nothing till i found myself lying there,' and she pointed down to the white sand, from which there came, through the sultry night, the gentle hiss of the sea, 'and saw you lying near me, and dead, as i thought.' 'nor do i remember, or only very little more than you can do. i dragged you from the saloon, and, after fixing a life-buoy on to each of us, leaped into the sea with you, striking out vigorously to avoid the ship. and i can recall my battlings with the waves for a few moments--only a few--then feeling my breath knocked out of me. and, then, nothing more until i came to and found you looking at me here. it was the life-buoys that saved us.' 'in god's mercy. under his providence. yet--yet--if it were not wicked to say so--if it were not for my poor dear mother at home--i--should----' 'no, no!' he almost moaned. 'no, no! not that!' then, after a moment or so of silence, he said: 'do you know how long we have been here? can you guess?' 'this is the second night, i suppose,' she answered. 'when i came-to yesterday morning, i imagine it was the first one after the wreck.' 'possibly. and have you seen nothing pass at sea, either near or far off?' 'nothing. yet i have gazed seaward all the time it has been light on each day. where do you think we are?' 'if the island is uninhabited, i think it must be one of the cormora group, since it can scarcely be part of the chagos archipelago--they are too far to the east. and all the others in the indian ocean--certainly in this part of it--are inhabited.' she made no reply now--she did not say what almost every other woman in her position would undoubtedly have said--namely, that she hoped they would in some way be taken off the island. for, in absolute fact, she did not hope so. to be saved from this desolation, to be put on board some ship which might be going to any part of the world, even though that part should be england itself, meant leaving gilbert behind--leaving him to his ocean grave. and she would not--certainly she would not yet--consent to believe that he had met with such a grave. the _emperor of the moon_ was still there, a part of her above the water although she was almost turned upside down, or 'turned turtle,' as she knew the sailors called it, and--and--might not some of those who were in her when she struck be still sheltering, clinging to some portion of the wreck that happened to be above water? she did not know much about ships, this awful, fateful voyage being her only experience, wherefore she thought and hoped and prayed that such a chance as this which she imagined in her mind might be possible. while, too, she remembered that gilbert and her uncle were both blind. therefore, if they were still alive, they could not cast themselves into the sea to escape out of the vessel--they would not, indeed, know that there was an island close to them, and, probably, would imagine that the ship was wrecked upon some reef or rock, so that it would be doubly dangerous to venture to leave her. and, again, even if they could by any wild chance have guessed that there was an island near, how would they in their blindness have known which way to proceed to reach it? thus, by such arguments, she had endeavoured to solace her sad, aching heart, and now, as she rose to leave stephen charke for the night, she put into words the thoughts which had been present to her mind from almost the first moment she had discovered that they themselves were saved. 'do you think,' she asked, standing there gazing down on him once more--'do you think any who were in the ship when we escaped can be still alive? is there any hope of that?' he looked up at her swiftly as she made the suggestion, then--because he felt that it was useless to encourage such vain longings--because, also, he knew that such a thing was impossible--absolutely, entirely impossible, he said: 'no, no! it cannot be. those who were in the cabin would be submerged as the ship went over, and those who were on the deck would be thrown into the sea.' she gave a bitter sigh as he answered her--and it went to his heart to hear that sigh, since now his pity for her was heroic, sublime, in its self-abnegation--as great as were also his love and adoration; then she asked: 'and where was gilbert--lieutenant bampfyld?' 'he--he--was lying by the wheel. god pity him! he was a brave, noble officer. even in his blindness he had crept up to help at the wheel, and was determined to do something towards saving the ship if possible. then--then--he fell down from exhaustion. he----' '--is dead!' she muttered, in a voice that sounded like a knell. 'dead! oh, my god! he is dead. i wish i were dead, too!' chapter xx 'i do believe you' she moved away from him now that the night was at hand, intending to seek a little knoll that was hollowed out by nature so that it presented the appearance of a small cave of about six feet in depth and the same in breadth. above it there grew, tall, stately, and feathery, two cocoa trees close together; around it trailed tropical creepers and huge-leaved plants which bore upon them large white flowers. it was into this cave she had crept the night before and had slept, and to it she now intended to go again, it being, as she thought, better perhaps to pass the night there than in the open air. yet, had she but known, it offered her no necessary shelter, since, in truth, none was required--especially at this season. dews scarcely ever arose in the island, there being little, if any, of that dampness at night for which the poisonous deadly west coast of africa is so evilly renowned, and one might sleep in the open air as free from the dangers of exhalations as in any closed place that could be devised here. but, not being aware of this--as how should she who, hitherto, had known so little of the world outside london--outside england?--she spoke to stephen charke ere she left him for the night, saying: 'i wish there was something to cover you with--something to protect you. yet there is nothing--not a rag.' 'it is of no importance,' he said, looking up at her, and able to see her face, pale and ghostlike, by the light of the stars. 'of none whatever. i shall be able to lie here and sleep very well. there is no fear of damp or fever in all this locality. i know it well. and, tomorrow, i hope to be able to get up and go about the island. perhaps, beyond that mountain at the back, there may be some signs of human habitation--of human life. do not think of me. good-night. sleep well. try to sleep well.' 'good-night,' she answered, 'good-night'; and then she slowly withdrew to the cave in the little knoll, and so left him. but, when she had gone, and had lain herself down upon the soft, dry sand within that cave, sleep refused to come to her. the night before she had slept long and soundly, perhaps because of all that she had gone through, and because also she was battered and bruised and weak after her immersion in the sea and the contact with the rocks. but to-night she could not do so--her mind was now triumphant over her body; the hour of that mind's agony was upon her. and she bent and swayed beneath this agony, and recognised, acknowledged, all the ruin that had fallen on her future life and hopes and dreams of happiness to come. her lover, her future husband, was gone--was dead! her heart was broken; there was in actual fact no future before her. she had loved him madly, blindly, almost from the first time she had set eyes on him, and now--now he was dead. there was nothing more. she would never love any other man; none other could ever find his way into her heart as gilbert bampfyld had done, nor set every pulse and fibre in her body stirring, nor cause her to thank god when she awoke each morning that another day had dawned when, even though she might not see him, she could still pass many waking hours in thinking of him. no; no other man would ever have the power to cause all that. henceforth, if she ever left this island alive, it would be to return to a joyless, hopeless life--a woman widowed ere she had become a wife. thus she thought and mused as she lay in the cave, her head supported on one hand while she looked out on all that devilish, cruel waste of waters which had hurled the ship to its destruction and slain almost every soul on board her, and which now--like some wanton trampling on the ruin and despair that she has caused--was smiling before her in the rays of a crescent moon that was just peeping above the eastern horizon. indeed, the glimmer which this young moon sent shimmering along the tropical sea was not unlike the false sad smile that a wanton's lips might wear in the hour of her victim's ruin; the smile that bespeaks 'the painting of a sorrow, a face without a heart.' a little breeze sprang up now, a ripple soft as a lover's kiss; balmy, too--as it played among all the rich tropical vegetation of the island--as a young girl's pure breath, and she saw that her fellow-castaway perceived it, since he turned himself so as to bring his face towards it--doubtless to cool his heated frame and to get relief from the warm, tepid air that hung all around--air that was like the atmosphere of a turkish bath. and this led her thoughts away from her own sorrows into the direction of those griefs which must be his--towards this brave, valiant man, who had saved her life at, as she knew must be the case, the risk of his own. his lot was also sad, she recognised, sad because he loved her--as it would have been the merest affectation for her to pretend to doubt--and because she knew that never could this love obtain that which it hungered for. yet, all the same, there had come into her heart a feeling of intense sorrow for him; sorrow and pity that had welled up into her bosom and was almost holy in its depth and purity. 'to love and lose, as i have done,' she murmured; 'to love and never win, as is the case with him. oh, god! could there be aught to make our bitterness--our lot--more terrible?' suddenly, she started and raised herself higher with her elbow, her nerves quivering, her heart beating violently, her eyes staring intently into the shade beneath a copse, in which grew in wild profusion a tangled mass of cocoa trees and tamarinds, of orange bushes and lemon trees, and into which, now, the new moon's rays were glinting. for she had seen something moving there--something creeping, crawling close to the ground--stealthily, secretly--as though desirous to approach the spot where they were both so near together, without being heard or seen. what new horror was this that approached them in the night, that crept in ambush towards them as though intent on secret murder and attack? what! some native of this horrid region lusting for the stranger's blood, or some wild beast as fierce! her; tongue cleaved to her mouth--she could feel that the roof of the latter was becoming dry--she tried to scream--and failed! and, still, close to the earth, that thing crept--nearer--nearer--and once, as it either pushed some underbrush aside or came more into view, a ray of the moon glistened on a pair of eyes, illuminating the pupils for a moment. then she found her voice and shrieked aloud: 'mr. charke! mr. charke! there is something creeping towards us. save us! save us!' in a moment he was endeavouring to spring to his feet, but this he could not do owing to his soreness and contusions; yet, nevertheless, he staggered up a moment later and gazed around, wishing that he had some weapon to his hand. that cry of bella's--it rang along the desolate beach as, may be, no woman's voice had ever rung there before!--brought matters to a crisis. there was a rush, a spring from the creature that had, by now, crawled so near to them; a spring which hurled charke back reeling as the thing passed him and then brought it, itself, close to bella, about and around whom it at once began to gambol, rudely and roughly, as some great watch-dog might do who had found its lost mistress. the creature was bengalee, the tiger-cub, and, in some way, it, if nothing else, was saved from the wreck of the _emperor of the moon_. 'oh!' cried bella, half fearfully at its furious bounds and leaps, which, even in her nervousness, she could not but construe into a wild, savage joy on its part at once more being in her presence, 'it is bengalee. oh, thank god!' 'thank god?' charke repeated, not understanding. 'thank god for what?' 'it is a sign,' she said, 'a sign that we are not the only ones who have escaped. think! think! if this creature could get ashore, so--so may others have done.' for a moment he said nothing, contenting himself with watching the exultation of the creature and in reflecting that it was her shriek which had told it who those were to whom it had drawn so near--with, perhaps, if stung by hunger and privation, a vastly different intention from that of fondling either of them! and he did think of what she hinted in connection with its safety and its having reached the island alive, as well as of that safety pointing to the fact that others, that human beings, might also have done so. only--he knew, and knowing, refrained from saying, that her deduction was by no means accurate. this animal had been on the deck when the ship heeled over on the reef; it was confined only in a locker from which it might easily have forced its way out in its terror, or, indeed, might have fallen out of it, but it was an animal, and its blindness had left it! gilbert bampfyld had also been on the deck, charke remembered, but was still blind. there was no analogy between the tiger-cub and any human soul on board. 'you do not answer,' she said, as now bengalee lay panting at her feet, its rough evidences of delight having ceased for a time; 'you do not speak. you think there is no likelihood of any others being saved from the wreck?' 'i cannot think so. heaven knows that, if i could comfort you with such hopes, i would. but----' and now he repeated aloud those silent thoughts and arguments of a moment ago; while, as he did so, he saw, in the moonlight, that she turned from him, and he heard her whisper low: 'heaven help me!' then, because her misery and woe struck like a knife to his heart, he said: 'to-morrow, if i am strong enough, as i think i shall be, i will make a journey round the island and explore every spot upon it, where, if--if any one should have, by god's mercy, been fortunate enough to reach the land, i must light upon them. believe me, nothing shall be left undone that i can do.' 'i do believe you,' she cried; 'i do, indeed. ah, mr. charke,' she almost wailed, 'how good and noble you are! oh that such goodness, such nobility must go for ever unrequited!' 'that,' he answered, and she, also, could see by the aid of the moon's rays that on his face there came a wan smile, a smile that had not even the ghost of happiness in it, 'that is not to be thought of--never. let us put away for ever all thoughts of my desires; let us think only of what we have to do. to find, first, whether, in providence, there should be any others who have escaped from the wreck, and, next, how we are to escape out of this. if there are other islands near here which are inhabited, no matter by whom or what, it may be easy.' 'and if not?' 'then we must wait until, by some signal or other which i may devise, we can attract the attention of a passing vessel. beyond this i can think of nothing.' 'oh!' she exclaimed, 'much as i long to return home to england, to my mother--i think only of her now, i have none other of whom to think--yet--yet, ah, i could not go till i was sure, sure beyond all possibility of doubt, that gilbert was not here or somewhere near. think, if he should be still alive and blind and wounded! here and unable to help himself. oh, it would be almost worse than to know that he was dead.' 'i do think,' charke answered; 'i understand. and until we are sure, one way or the other, we will not go: no, not even though rescue came to-morrow.' then, looking down at the tiger-cub which had now risen to its feet again, and was pacing restlessly about with the sinuous, lithe movements peculiar to its race, he said: 'but there is also one other thing that must be done. that creature is now beyond control, even by you; and these beasts are treacherous to the core. if it is to live, and we are to live also, it must be secured--made prisoner. otherwise something terrible will happen. i know it; feel sure of it.' chapter xxi washed ashore they had both slept again by the time that the morning broke with the suddenness of the tropics, while the coming of the sun was heralded by the pale primrose hue which all who have been between capricorn and cancer know so well; that hue being followed by the vermilion and golden shafts of light, and then by a deep blood-red tinge which suffused all the horizon. they had slept uneasily, each in their place; with--outside, near the opening of the little cave under the knoll--the tiger lying tranquilly as though keeping watch and ward over her whom, probably, it deemed its friend and mistress. yet, ever and again, as she, while waking to regard it more than once--because of the fear which stephen's words had engendered in her mind--saw very well, its yellow eyes peered out restlessly from their closed slits of eyelids, the pupil of each eye being itself a horizontal slit only. and she acknowledged that charke had spoken aright, that the time had come for the creature to be either imprisoned or made away with. all its evil instincts were undoubtedly being developed with its growth; soon, they would have obtained their full force and be, perhaps, exerted. it was time. but now the dawn was come, the blood-red of the eastern sky was plainly visible, and the birds of the island were twittering to each other and pluming themselves; whereon the girl rose and left the cave, and passed quietly by the creature lying so close to her as though in fear of arousing it. in actual fear of it, indeed, since she did not know but that it might turn and rend her at any moment. for it was big enough and strong enough to do so now, its size being that of a large retriever, or a year-old mastiff; and she, or he, even--that stalwart muscular sailor--would probably have had little chance against it if it had set upon them, since both were unarmed and both were weakened and broken down by their struggles in the tempest-tossed waves. charke, seeing the girl rise from her recumbent position, rose also, quickly and quietly, and came towards her, while as he did so he said: 'now, to-day is the time for me to make that search round the island which i promised you. we will but eat a little fruit, and then i will set out.' 'shall i go with you?' she asked, as, taking up the cocoanut shell, she turned to go towards the rivulet that ran at her feet, 'or is it better for me to remain here? perhaps, too, it may be more than i can do. or, indeed,' she hastened to add, 'more than you can accomplish in one day, and in such heat as there will be. oh, mr. charke,' she continued, 'you are not strong enough to undertake it yet!' 'i feel strong enough this morning,' he replied, 'and, if i cannot make the whole tour of the place in one day, i can at least do a considerable part of it. i will begin at once, before the sun becomes too fierce. but, as for you, perhaps it would be best if you stayed here. the outlook from this portion of the island is, i think, the one from which any ship that happened to pass would be most likely to be observed. you see, we look west from here, towards where africa lies, and vessels use that track in preference to running more out into the open.' 'i will do anything you suggest,' she said. 'anything you think will be for the best. but'--and again there came upon her face that stricken look which made his heart so sad for her, and which, whenever he observed it, caused him to bury every sorrow for himself in a more profound and unselfish one for her--'but--you know--i--i--at present--just at present--for a day or so--do not wish to see a ship come here to rescue us.' 'i know, i know,' he answered, not daring to keep his eyes fixed full upon that lovely but unhappy face. 'i know. well, we will not look out for rescue yet. but, still, i think you had better stay here. we do not know for certain the size of this island; it is only guesswork on my part. it may be too far a walk, too much of an undertaking for you. you are not afraid--of that?' he continued, as he directed his eyes towards bengalee, while seeing how, as he was speaking, she, too, had let her glance fall upon the cub, which was now pacing restlessly about at their feet. 'no,' she said, 'i am not. yet what you said in the night was true. it is growing beyond control, and, of course, i know how treacherous and savage these animals are. it was a piece of girlish folly on my part to beg poor uncle to save it.' 'i scarcely know how we are to make away with it,' he replied. 'i have nothing but this,'--and he took from his pocket a little white-handled penknife, which he had probably bought for a shilling off a card exposed in a london shop window. 'i could hardly kill it with that. however, one thing is certain, it will die of starvation ere long on this island. it cannot live on fruit as we can, nor catch birds, and there are no signs of animals, not even rats or mice, as far as i can see.' 'oh, poor thing; what a dreadful death to die!' the girl exclaimed, her pity at once awakened for a creature which had been more or less her pet for some few weeks. yet she hastened to ask if starvation did not make such animals even more fierce than usual, and if the risk to them both would not, thereby, be increased. then, before he could reply, she suddenly exclaimed, as her glance fell on the sea, 'what is that out there? surely--surely--it is not a drowned man? oh, not that--not that!' following the direction of that glance, he saw something drifting about on the tranquil, almost rippleless, water over which by now the rays of the risen sun were gleaming horizontally. something that, since it was end-on towards them and the island, was not easily to be distinguished, yet was, all the same, undoubtedly no drowned man nor human body, alive or dead. at first he thought it might be a dead shark--his knowledge of the sea telling him at once that it was not a living one, since they never expose aught but the dorsal fin when swimming--then, a second later, he recognised what the object was. 'no,' he exclaimed, anxious to appease her terrors at once--while knowing to whom, and, above all others, to whose _dead_ body those terrors pointed--'no, that is no body, living or dead. instead, it is one of our quarter-boats. washed out of the chocks when the ship turned on her side, no doubt, and floating about ever since.' 'it is coming nearer,' bella exclaimed, her eyes still on it and full of delight at hearing that in it there was, at least, no confirmation of one awful fear; 'do you not think so?' 'undoubtedly it is coming nearer. it will strike the shore just there if the reef does not catch it'; and he pointed with sailor-like certainty to a spot close by. 'it will be a mercy if it does.' 'why? we could not escape from this place in that, could we?' 'hundreds of sailors have escaped death in smaller boats than that; ay, and lived for many days, too, on an open and rough sea in such boats. but it is not for that only. if it comes ashore i can make a visit to the poor old _emperor_ and find out something, if not all, that i--that we---want to know. while, though we need not put to sea in it, we may use it to get to some other island which is inhabited, by, perhaps, white men; but, anyhow, by some one. it will be of the greatest assistance, especially as, since it floats, it must be undamaged. i trust the oars, if not the sail, are in it.' and now, listening to his words, bella became as eager for the quarter-boat to come ashore as her companion was, and, together, they went down to the spot he had indicated as that which the boat was likely to arrive at--a spot about sixty yards from where they were. as bella walked by her preserver's side she was wondering many things, and especially if he would, indeed, be able now to discover what the fate of the others in the _emperor_ had been, and, above all, if, by the aid of this boat, he would be enabled to solve for her the question she hourly, momentarily, asked herself by day and night--the question whether there was any hope left of a life of happiness and bliss to be passed by her lover's side, or whether, for her, the future could bring nothing but a joyless, heartbroken existence henceforth. also, she mused upon one other thing--namely, what charke was thinking of while, with his eyes never off the incoming boat, he meditated deeply as, from his knit brows and fixed look, she felt sure he was doing. the thoughts, those that actually were in his mind, he would, undoubtedly, not have divulged, even though she had asked him to do so, since they were such as could only have caused grief unspeakable. for he was thinking that, since this quarter-boat had been washed out of the chocks and off the deck into the sea, and had then floated about for forty-eight hours in the neighbourhood previous to being directed by some subtle current to the island, so other things that were on deck would be subject to the same conditions. the bodies of drowned men; the body of her lover! he knew that the sea and its currents and tides work in calm weather with as much regularity as the sun and the moon work in their rising and setting, and, indeed, as the seasons themselves work; and he knew, also, that if gilbert's body--which was close to where the quarter-boat rested when the ship struck--had been washed into the sea at the same time as it, then it was most probable, nay, almost certain, that it also would come ashore at the same spot and perhaps almost at the same time. what horror, what fresh horror, would that be for this poor devoted girl to experience! for, in his own heart, he never doubted for one moment that somewhere close at hand the body of gilbert bampfyld was floating about. the boat was coming very close into the shore now, so close that they could see that one oar was in it, but only one, and that there was nothing else, while they observed, too, that the rudder was not fixed in the braces. yet that mattered little to stephen charke if he could only once get possession of the boat itself, since with one oar on such a glossy sheet of water as this ocean was now, he could propel and steer it easily enough. 'i am glad, thankful, it is coming ashore,' he said now. 'i had thought of swimming out to the ship, only i dreaded the sharks. little use as one's life may be, one would scarcely care to lose it by the jaws of those brutes.' and, though he did not see it, the girl by his side gave him a glance such as would, perhaps, have cheered his heart had he done so. 'was not her own life, also, of little enough use,' she asked herself as he spoke, 'to make her sympathise with his remark? would it not be a broken and dejected one, henceforth, if that which she dreaded, which she had almost forced herself to feel sure must be the case, should be proved to be so beyond all doubt before many more hours had passed?' for every hope with which she had buoyed herself was sinking in her breast, as moment after moment went by and the time grew longer and longer since the wreck had taken place. the boat touched the white, pebbly beach now, grating on it with a gentle scrape, and stephen, who had gone close to the water's edge to await its arrival, put out his hand, and, seizing first the stern and then the painter, drew it a foot or two farther on shore. then he got into it, and, grasping the solitary oar which had remained in the boat simply because the loom, or handle, had got caught beneath the stern thwart, prepared to shove off in it. 'you will not mind,' he said, as he did so, 'being left alone for half an hour? this will not take me away from you for so long as when i go round the island.' while she, in answer, shook her head to indicate that she was not at all afraid of being left by herself. chapter xxii a sailor's knife 'she is perfectly sound and watertight,' he called back to her as, with the hand which was uninjured, he threw the oar over the boat's stern, and worked her out from the shore. 'if we want her to help us off to another island she will do it, if i can only find another oar floating about somewhere.' then he propelled her as swiftly as he could to where the _emperor of the moon_ lay outside the rock, her keel and copper bottom gleaming in the bright morning sun. as he drew near to the ship he began to perceive how all hope of the likelihood that any one should still be alive and imprisoned in the ship must be abandoned. she had turned over even more than he had at first imagined when regarding her from the shore of the island, so that the keel was almost level in a manner exactly the opposite from what sailors mean when they talk about a 'level keel.' it stuck up now, so far as it was out of water, as some sharp mountain ridge seems to stick up when regarded from a valley, and showed an almost horizontal line; while, beneath the keel and above the water, for half the length of the vessel, there was visible a portion of the outside of the main hold, down to (or up from) her diagonal ribboned-lines. and, here, there was a great gaping wound, a hole smashed into her side large enough to have let the whole indian ocean pour into the devoted ship directly it was made, and (although there might well be others which were not visible) sufficient to have filled and sunk, forthwith, the largest vessel that was ever launched. the force of the impact was to be appreciated, too, by the manner in which her copper sheathing was driven into her and burst, so that, where the blow had been struck by the jagged tooth of the rock, the latter looked like a destroyed _chevaux-de-frise_, or, for a better comparison, a paper hoop through which an acrobat had passed. and, in this burst and broken protection, as in other and less terrible circumstances it might have been (though naturally it had proved useless here), the sheathing-nails stuck out like brilliant, gleaming yellow teeth, all broken and distorted. charke brought the quarter-boat alongside the upturned or leaning bottom, so that, by looking through this gaping wound, he could peer into the now reversed decks and see that there lay, on what had once been the roof of it but was now the floor, a mass of articles, such as is usually stowed away in a ship's lower decks. a mass, composed of cables and old and new sails, as well as some stores, consisting of dozens of tinned-meat cans unopened, boxes of sardines, and so forth, and several old sea chests and trunks--all lying, of course, helter-skelter, as they had been thrown together by the ship's reversal. 'there are some things of use here,' charke thought, 'and worth taking away,' whereupon he ran the painter through a small hole in the sheathing and tied it tightly, and then scrambled up the vessel's inverted side until he was able to drop himself through the opening into the deck, taking care that he tore neither his flesh nor his clothes in doing so. being there, he selected a small sail which he found; it was indeed, a boat sail, and had its gear of mast and tackle attached, while, passing it through the orifice, he dropped it carefully into the boat, and then he took next a few of the tins of provisions, and dropped them into her, too. and, also, he found something which would be to him, in the utterly unprovided condition in which bella and he had escaped to the island, of the greatest service. this was a long, sharp knife in its leather sheath, such as sailors strap to their sides, and was new and in good condition, so that he did not doubt that the last seaman who had been sent below to this deck had dropped it there, and he was able to picture to himself the man's annoyance, probably expressed aloud and with a good deal of vehemence and strong language, over his loss. this done--and the doing of it had not taken long--he prepared to leave the disordered hold, when he remembered that there was one thing he wanted, namely, some cable. 'that tiger has to die at once,' he muttered to himself. 'with a piece of stout rope and this knife--which would slay anything, from a horse downwards--its death should not be difficult of accomplishment.' then, having selected two or three pieces of cable of different strands, he got out through the hole again and into the boat. it is almost needless to write down that he found no sign of human life as he rowed about and round the wrecked _emperor of the moon_ for some moments afterwards. needless, too, perhaps, to add that he had never expected to find any. he was a sailor, accustomed to disaster at sea and full also of much acquired knowledge pertaining to many of the calamities which it had never been his lot to experience heretofore; and he knew--he felt sure, and would have staked his life upon the certainty of his convictions--that of all who had been in that doomed ship an hour before she struck, none except bella waldron and himself were now alive. those who had been below in the cabins or saloon, those also who were in forecastle or galley, had met, must have met, not only with their deaths but their graves at one and the same time; while as for the unhappy and blind young officer who had caused him so much heartache by winning the woman whom he loved so fondly, and whom he had once hoped to win--why, it was impossible that he should still be alive. if he had been washed ashore, it could be only as a corpse, and it was most improbable that even that should have happened. in truth, he believed that, with all the others, he had been carried below by the overturning of the ship and then pinned down, buried, beneath the mass of the fabric. otherwise, since the boat had floated ashore, so, too, would he have done by now. 'the woman he had hoped to win,' he repeated softly to himself, as still he sculled the quarter-boat round and round while peering down into the dark blue depths as far as he could penetrate; and while endeavouring also to perceive some sign or memorial--even so much as a cap or straw hat--of one of those poor drowned sailors imprisoned below--'the woman he had hoped to win!' and as the phrase rose to his mind, though not to his lips, he recalled as well how he had cherished the thought of the length of voyage that had lain before her ere she could join her lover in india; how, too, he had pondered on half a hundred things which might happen ere the old _emperor_ should be anchored in bombay harbour. almost, now, those meditations seemed to have been prophetic--for what had not happened! the girl's lover was gone, removed by death, and she had none other in the world on whom to lean but himself. and what was more, she spoke kindly to him; she pitied him, he could well perceive; there was something between them now, a deep sympathy, a reliance on each other in their misfortunes, which had never existed before. 'the woman he had hoped to win?' well!--he scarce dared whisper the thought to his longing heart, yet it was there!--the thought, the hope that in days to come, in after-months, perhaps years, when her grief for gilbert bampfyld was mellowed and softened by time, when she knew him better and should fully recognise how profound his adoration for her was, he might still win her! she could not, young as she was, and with all the years of a long life before her, sorrow for ever--sorrow for a memory that would at last be nothing but a shadow. 'he _would_ win her!' he said aloud to himself now, as he worked the boat ashore, 'he was resolved he would.' the one obstacle in his path was removed, the brave, gallant young officer was gone, brushed aside by fate. he would win her yet! he stepped ashore now to where she was standing watching him, and it seemed almost--if his recent thoughts had not tinged his present fancies with a roseate hue--that there was a look of greeting and welcome to him in her eyes, even as she saw that he had come back--even at the ending of so short an absence as his had been! was she beginning now--now that she had none other in the world to watch for--to desire to have him always near her? ah, if that were indeed so! then--then he might win her at last. 'you found,' she asked, speaking low, and in those sad tones which had come into her voice of late, and since disaster had fallen heavily on them, 'you found no sign of any others having been saved?' 'no,' he said, also softly. 'no, there are no signs of that. miss waldron--i am neither cruel nor hard of heart, but--oh, how can i say it!--it is useless to hope.' 'useless! ah, well, i suppose it is--it must be! and, god help me, it must also be borne.' then she turned away from him with the desire to prevent the tears which had risen to her eyes from being seen by him, and went back to the shade of the trees under which she had been sitting until she saw the quarter-boat returning with him in it. and he followed her, carrying the cable which he brought away from the ship; the knife which he had found being in his pocket and the sail with its gear left in the boat. the sun was terribly fierce now, so fierce that to be beneath its rays for only a few moments was to risk sunstroke or to be burnt more red than he had long since been, or she since her exposure on the island; and, of course, he could not attempt the projected tour of the place until that sun once more sank low in the west. there was, therefore, nothing now to do but to sit idly gazing out to sea and watch for signs of any ship which might pass near enough to perceive them, when they should have erected signals. 'after the tour round the island,' he said to her, as he sat by her side beneath the palm trees and occupied his time in plaiting some of the long, thick grass which grew at their feet into something that should serve for hats, or, at least, coverings for their heads, 'after the tour, when we have had the last sad satisfaction of knowing that there can be none who have escaped, you will not object to my endeavouring to arrange for our being taken off? the mozambique channel is full of ships on their way to india during the time of the southwest monsoon--you will let me make signals, will you not?' 'i am in your hands,' she replied, her eyes on him. 'you must do all that you think best. ah, mr. charke, you do not know how grateful i feel to you!' 'never say that. not a word. i knew, i thought, i could save one besides myself, and, naturally,' he went on simply, 'i saved you.' then both sat on musing and meditating in silence. 'here comes the tiger,' he said now, seeing the creature stalking towards them in the lithe, treacherous manner peculiar to its race. 'i imagine it has been endeavouring to find food. i brought off some tinned things from the ship; yet, cruel as it seems to be, it is not advisable, i think, to give it anything in the shape of flesh. meanwhile, if it will only go to sleep we ought to secure it,' and, as he spoke, he took up one of the pieces of cable and commenced tying what is known to sailors as a double-diamond knot. but, previously, he had fastened the other end securely round one of the palm trees that grew close by him. 'there will be one advantage in this,' he said, 'namely, that the more it pulls against it the tighter will come the loop, so that its intelligence will prevent it from straining at the rope and strangling itself.' 'poor wretch,' bella exclaimed, 'how gaunt and lean it is growing! i recognise that it cannot be kept alive or even taken off with us when we are found here; yet--yet i am sorry for it.' 'yes,' he answered, 'i understand that, but it has to be done--must be done--it is imperative. in the state it is now in from hunger, and also owing to its increasing strength, our lives are no longer safe with it, and certainly not with it at large; while, if one of us were to scratch our hands, or even get the slightest wound, and the creature smelt the blood, which it would undoubtedly do--well, the result might be terrible. now, see, it's going to sleep; it appears exhausted. i must drop the loop over its head.' 'no,' she answered, 'let me do that. it is still very docile with me,' and, as she spoke, she took the loop from his hand and, while patting the creature's head--whereon it raised it as a dog will raise its head when stroked by a loved hand--she dropped that hand down until the rope was round its neck, though not without muttering some words of regret as to what she deemed her treachery. 'it is no treachery,' he said, 'no more treachery, indeed, than to tie up a mastiff in its kennel. and, even though it were, it would not matter. these creatures are themselves the incarnation of treachery. however, the main point is that it is now secure. it is not yet strong enough to burst this rope.' such was the case, yet it was strange that to so acute a mind as charke's there had not occurred the idea that it would not take a tiger very long to gnaw a ship's rope through if it desired its release. chapter xxiii 'the tiger did that' when the sun began to drop towards where africa lay, afar off and invisible, and when (because of the dense foliage which crowned the slopes of the island that rose behind the beach) that portion where they sat was rapidly becoming shaded from its burning rays, stephen charke said that the time had come for him to think of making his tour of the place, or, at least, of accomplishing a part of it. the air, it is true, still resembled that which one feels when they have approached too near to a furnace, or, for a further simile, have descended into the engine-room of a steamer. yet, now, there would be no danger of sunstroke, and the expedition, such as it was, might very well be undertaken. 'my idea is,' charke said, 'to begin now, this afternoon, by starting to the left and going on along the shore until i am nearly opposite this place on the other side of the island; then i will come back here, crossing it, and to-morrow i will do the same thing with the other side. that way there cannot be much left unexplored by to-morrow evening. what do you think?' 'i think,' bella answered, 'that you are the most unselfish, heroic man i ever knew. ah, mr. charke,' she continued, 'i know very well why you are doing this, why you are going to make this journey round the island. it is to satisfy me, it is for my sake. if you were alone here you would never do it, but occupy yourself only on thoughts of how to get away, and----' 'no,' he said, 'no. had i been the only person who got ashore from the wreck i should, as a sailor, as a comrade of the others, have deemed it my duty to make a thorough search through the island ere i took steps to quit it. i shall have, as the survivor of the _emperor of the moon_, to make a report----' 'i understand,' she said quietly. 'i understand. nothing that you can say will make me feel my obligations to you any the less.' for bella waldron knew as well as stephen charke himself knew, that what she had just said was the absolute fact; she knew that he was going to undertake this fresh toil--for toil it was, after all he had gone through, after his bruises and buffeting with the waves, and in this terrible torrid-zone heat--for her and on her account alone. he was going to undertake it with the desire of easing her heart and preventing her, in after-years, from being able to reproach herself with having left the spot while any chance remained of there being one of those who were dear to her upon it. she was, too, perfectly aware that he did not for one moment believe--alas! how could he, a trained, intelligent seaman, believe?--that there was any other soul left alive out of all those who had been in the ill-fated vessel when she struck on the rock. and, being thus unable to believe, could she regard him as aught else than that which a moment before she had termed him, 'a most unselfish, heroic man'? before he left her he asked if she would not partake of some of the tinned meats, or sardines, which he had managed to obtain from the upturned hold, but as the girl replied that it was far too hot to eat anything but the wild fruit growing in such profusion all around, and also that she was not hungry, he decided that he would not open one of the tins for himself. he, too, could do very well on what there was to their hands for the trouble of picking, since, here, in this tropical, steaming atmosphere, eating scarcely seemed a necessity of life; while, if it were, then those glorious bananas whose golden and crimson hues merged so superbly into each other were amply sufficient. but, also, he had another reason for not opening the preserved meat. the odour of it would--might--arouse the cub's desires, and, once aroused, they would possibly stir the animal almost to frenzy if ungratified. he rose now and prepared to set out, there being still two full hours of daylight left; two full hours ere the sun would be gone and the swift, dark night had fallen at once upon all around--the outcome of a dusky veil which the sun appears to fling behind it as it departs, and out of which emerges black obscurity, lit only by the burning, silvery constellations. but, ere he went, he asked if she feared to be left alone for so long. 'no,' she replied, 'no. why should i? what is there to hurt me here?' 'there may be people on the island all the same,' he replied, 'even if they have not yet discovered our presence; although i do not think it likely.' 'nor do i. if there were they would by now, in two days, have observed that,'--and she pointed towards the wreck--'and have come down to it. we are alone,' she concluded with a sigh. 'there is no one else here but you and i.' and still again she sighed. 'yes,' he answered, understanding all that her words meant, all the heartbrokenness that they expressed. 'yes, we are alone; there are no others.' after which he left her, saying that, by dark, or very shortly afterwards, he would be back again. when he had departed, after looking round once to wave his hand ere a bend of the shore hid him from her view (and she noticed that, true to his sailor's instincts, he went towards the boat and inspected it, and then drew it up a little more on to the white-pebbled beach and made the painter more secure), she went down to the rivulet and cooled her face and hands and feet in it, and made some attempt at arranging her hair, while using the stream as a mirror. yet it was little enough that she could do in the way of a toilet, since she had nothing that would serve as a comb nor any soap or towel. after which, feeling refreshed, nevertheless, by this attempt, she returned to where she had been sitting and gazed out seaward, meditating deeply. 'what an end,' she murmured, as she did so, while from her eyes the tears flowed freely now--the more so because there was none to observe them--'what an end to all! gilbert, who was to have been my husband, dead! gilbert, whom i so loved with my whole heart and soul, dead! and lying beneath that ship. oh, gilbert, gilbert, gilbert, my love, come back to me. and my poor uncle and aunt, too. oh, god, what a disaster! what a disaster!' and now she wept piteously, so piteously that, if that other man, who had risked his own chances to save her as well as himself, could have seen her, the sight would have gone near to break his heart. that other man! at this moment her thoughts turned to him too. almost unconsciously she found herself thinking of him, speculating on what his future would be. 'he will never marry,' she murmured. 'i know it. feel sure of it. it would be the idlest affectation to ignore his sentiments for me. yet--yet--how sad, how mournful a life must his be henceforth; no home to go to, no wife to welcome him, none to make him happy. poor mr. charke. poor stephen. our lots will be similar, we must be friends, always friends.' meanwhile, he was making his way along the beach, which was still shaded from the sun and becoming, indeed, more and more so as he progressed farther round the island, away from the west. and every step which he took served only to confirm him in what he had believed, known from the first--the unlikelihood of there being any other person saved from the wreck. 'surely,' he muttered to himself, 'if he should have drifted ashore, it would have been here. the current sets this way, and also the monsoon blows towards this island. living or dead, he would have come to this neighbourhood if he had come at all. the tiger did that, and, doubtless----' he paused at those words. 'the tiger did that!' and for a moment it seemed to him that his heart stood still. 'the tiger did that!' ay, but did it? was he wrong in the surmise, wrong in his deduction? did the cub land here or hereabouts? reflecting, recalling the night before, the early dawn, when bella shrieked to him and awoke him from a half-slumber into which he had fallen, he recollected that the beast had sprung forth from the copse of orange and lemon trees that was to the right of the little spot where he had waded ashore with the girl in his arms, and where, after carrying her up far above the waterline, he had dropped senseless. it had sprung at them from the right side, was coming from the right; and it was not to be believed, it was, indeed, beyond all belief, that it could previously have passed across where they were from the other side without having been noticed by one of them, especially by bella, who was wide awake. it was coming from the right; it had, doubtless, therefore, got ashore, been cast ashore, to the right. and he was seeking for signs on--had set out to--the left! had he, therefore, chosen the most unlikely place in which, if, by the most remote chance, any human being should have been washed ashore, to discover them? 'shall i go back,' he mused, 'and begin again on the other side? shall i?' yet, as he meditated, he reflected that there would be little use in doing so; certainly little use in doing so to-day. an hour had now passed, or nearly so, since he quitted bella; the sun, he knew, since he could no longer see it, was sinking fast--over the whole of the rich, luxurious vegetation that stretched inland there was now the golden hue, the amber light that, in the tropics, follows after the dazzling, blinding, molten brilliancy of the noontide, directly the sun is no longer vertically above the globe. and also, there was the odour of the coming night all about him, the odour of the declining day when, from every fruit and flower that has drooped through the hottest hours of the earlier portions of that day, there exudes the luscious, sickly scent that travellers know so well. 'no,' he said to himself, 'no. it would be little use to turn back now or to begin again to-night! and--and,' he murmured, thinking deeply as he did so, 'even though he had been cast ashore, he could not now be alive. blind--unable to see his way--to find any of all the fruit that grows here in such profusion, poor bampfyld would succumb to starvation, even if the life had not been beaten out of him by the waves.' it was of gilbert bampfyld alone that he thought, of him alone about whom he speculated, since, of all the others who had been in the _emperor of the moon_, he was the only one whose body could by any possibility have come ashore. they, those others, pooley and his wife, were in the submerged cabin, no power on earth could have got them out of it; any men left in the galley and the forecastle were in as equally bad a plight. nothing could have saved them, or have even released their bodies. but, as he thought of gilbert bampfyld, so he felt sure that he also must have perished, even though he was not thus below as those others had been. still musing on all this, but with one other image ever present to his mind--the image of the woman he loved--dishevelled and storm-beaten, but always beautiful--the woman of whom, now, he began to dream once more, to dream of winning for his own in some distant day--he went on along the beach, his eyes glancing everywhere around and near him. glancing into the wild, tangled vegetation, along the channels of the rivulet's courses, but sometimes with them fixed on the beach. suddenly he stopped, his heart quivering again, beating fast. at his feet there lay a sailor's rough jacket, and, a little farther off, a cap--a common, blue-flannel thing, such as the mercantile sailor buys for a few pence at a ratcliffe highway slop-shop. he stopped, regarding them--not with that agitation which the greatest romancer who ever lived has depicted as clutching at crusoe's heart when he saw the footmarks, but, instead, with a feeling of astonishment; yet a feeling of astonishment which, he told himself, he, a sailor, ought not to experience. 'do not all wrecks,' he muttered, 'send forth around them countless articles of débris, countless portions of the raffle that encumbers their decks? what more likely than that a sailor's jacket and a cap should have floated ashore?' then he stooped, and, feeling them, found that they were thoroughly dry, so that they must have been ashore for some hours at least, since even the fierce sun of the now declining day could not have dried them in less time, all soaked with water as they had been. chapter xxiv beaten! defeated! 'no,' he said to bella some time later, and when he had returned to her, 'no other signs than these. nothing,' while, as he spoke, he pointed to the jacket and cap at his feet. he had brought them with him after the discovery, thinking that perhaps they might be useful when the time came for them to set out in the quarter-boat, as he fully imagined they would have to do, thereby to reach some other island. 'yet,' she whispered, 'if they, if this animal, too,' indicating bengalee, who now, what with his being made prisoner by the rope and also by his long fasting, displayed a horrible state of nervous agitation, a state which frightened bella and rendered even charke very uneasy, 'if they could be thrown ashore, why not others? mr. charke, do you think there is any hope?' 'i cannot buoy you up by saying that i do think so,' he answered. 'yet be assured of one thing--you will know soon now. to-morrow, at the first sign of dawn, i set out to accomplish the inspection of the other half of the island. it is smaller even than i thought; it will not take long.' and at daybreak he roused himself to carry out his undertaking, though, even as he rose from the warm, soft sand on which he had lain, he knew, he felt sure, that he was going on a bootless task. again and again he had told himself, through the night, that, even though gilbert bampfyld's body had reached the island, it had never done so with life in it. yet he would make sure for her sake and for his. 'heaven bless you,' she exclaimed from where she also rose as she saw him do so, and while going towards him. 'heaven bless you. you spare yourself no trouble nor fatigue on my account.' 'it is best,' he answered, though he scarcely knew what reply to make. 'it is best that there should be no chance lost. if--if----' then he held out his hand to her as he had not done before, and at once, after she had taken it, set out upon the remaining portion of his search. and, for some reason which he, perhaps, could not have explained to himself, he cast back no last look at her in the swift-coming daylight--nor gave any word of farewell as he had done on the previous afternoon. that daylight brought a little breeze with it which was cool and soft as it came off the ocean that, for some hours, had been free from the burning rays of the sun; and charke made his way along the beach while glancing everywhere, as he had done during his search of yesterday,--into every spot wherein, if any one, anything, had come ashore, they would probably have been cast. but as it had been when he proceeded towards the left or south, so it was now as he went towards the right or north end of the island. he found nothing; not even, this time, a rag of clothing or a spar from the ship. he observed, however, amongst other things of which his vigilant eyes took notice, that here the formation of the island was considerably different from what it had been on the southern side. there, as he made his way back inland to bella, cutting across from the eastern to the western shore, he had found the glades and groves almost flat, except for small knolls and little eminences on which, as everywhere else, there grew the long, deep-green grass, the cocoa trees and tamarinds, and the flowering shrubs and bushes. but here, upon the side he was now following, all was very different. inland, he could perceive that the surface rose until it developed into quite high hills, and that those hills, forming into spurs as they ran down to the water's edge, created a number of little bays or coves, some of them being scarcely more than fifty yards in breadth. also he perceived that on high, where the crests or summits of these spurs were, their sides were abrupt declivities resembling often the sheer sides of cliffs instead of sloping gradually and being covered by the deep emerald-green, velvety grass. and they were white as english cliffs--as those of dover!--and, sometimes, as precipitous. huge masses, too, of fallen, crumbling rock lay tumbled together at their base and in the tiny valleys which they formed between them, and gave, thereby, signs of either a convulsion which had some time or another taken place, or of their lack of solidity and insecure composition. 'i shall have,' charke thought, 'a mountainous, up-and-down kind of return journey if i go back to her inland. yet it will cut off a good deal of the way and make it easier for me.' he found as he progressed, however, that soon, if he wished to continue his inspection of the whole of the coast, he would, in any circumstances, have to continue his walk more or less inland, since now he could observe, by looking about, that the spurs ran quite out into the sea, so that they hid each little bay from its neighbour on either side of it. consequently, if he wished to inspect the space between each, he would have to mount to their tops and thus peer down into the recesses that they formed. at present, however, there was no necessity for him to do this. still looking, he saw that there were three more bays, or coves, which he could reach by walking between the feet of the spurs and the water, the spurs stopping some yards short of the gentle surf which the morning breeze was raising. 'three,' he said, 'three. this one where i am now, the first; then two more. and, after that, i must ascend and gaze down. there will be no getting farther along the bank.' so he entered the first cove, finding it as desolate and bare as the others into which he glanced in his journey; bare of everything, and with its white beach so void of all else but its own stones, that it might, that morning, have been swept clean and clear. the second was the same, except that here, upon its beach, there lay the long iron shank of an anchor with one arm and fluke upon it, but with the other gone. an anchor that, he knew at a glance, had never been made in recent days--that, by its quaint form, must be some centuries old. and, even as he continued his journey, he wondered how it had come there, and if, in long-forgotten and unnumbered years, some toilers of the sea had been flung ashore in this spot, and if this was all that had been left by time to hint at the story. then he entered the third, and last, bay or cove which remained passable by the shoreway--the last he would be able to inspect until he ascended to the cliffs above. as he did so he started--knowing, feeling, that beneath his bronze and sunburn he had turned white--recognising that he was trembling with a faint, nervous tremor. for this cove to which he had penetrated was different from the previous ones; it ran back between the two spurs which formed its walls until it merged into the wooded, grassy declivity that sloped down from above, while, at the foot of that declivity, was more grass forming a little carpeted ravine and, growing on it, some of the island trees--orange trees, lemon trees, even bananas. and on the grass there lay a man. dead or asleep! a man, fair-haired, clad in a white drill suit with brass buttons--they glistened now in the rays of the risen sun!--the white uniform of the royal navy. a man who was gilbert bampfyld. his heart like ice within his breast--all was lost now, every hope gone that, of late, he had once again begun to cherish!--stephen charke advanced to where that man lay, and, approaching noiselessly, looked down on him. looked down and recognised that here was no sign of death or coming death; that the man was sleeping peacefully and calmly; that he was rescued for the second time within the last month from a sudden doom. he also saw something else--he observed that bampfyld had recovered his sight. this he could not doubt. near him was some fruit which he must have gathered recently. and he had pulled down some of the branches of the trees which grew close by, and had shed them of their leaves, upon which he was now lying, they making an easier pallet than the grass alone would have done, while charke perceived, also, that he had been fashioning a sturdy branch of the tamarind into a stout stick. doubtless, he had recovered his sight through the shock of his immersion, when the ship heeled over. strong, determined, masterful as stephen charke had been through all the disasters which had overwhelmed the _emperor of the moon_; brave and stalwart as he had shown himself when, with none other left to command the doomed ship but himself, he had helped to furl and unfurl sails, to steer like any ordinary seaman at the wheel, and to endeavour manfully to hold the vessel up and ward off instant destruction--he was beaten now. beaten! defeated! and he felt suddenly feeble, so feeble that he was forced to sit down by the saved man's side, while doing it so quietly that the other did not awaken. beaten! defeated! ay, and with nothing left of prospect in the future, nor ever any hope. nothing! nothing! nothing! what had he hoped? he found himself asking: what, in these last few days? what dreamt of? a home, a wife; perhaps, in the future, children waiting for his return, running to meet him and to beg for stories of the sea, of tempests surmounted, of dangers passed. now, there would never be any home, nor wife, nor children. nothing! he had loved one woman fondly, madly; the one woman in all the world for him. until ten minutes ago he had believed that, some day, he would win her. and, now, it was never to be. his home would be the desolate home which the sailor ashore inhabits; his existence a long series of toiling across the seas in any ship wherein he could find employment, first one, then the other, for poor wages and without one gleam of sunshine to cheer him. what a life! and--and it had seemed, only an hour ago, that all was likely to be so different. she, bella waldron--his love--no, not his! never his now--was being drawn towards him, she relied on him, trusted in him; but, henceforth, she would need him no more. this other had come back, would come back into her life again, and--he would go out of it for ever. god! it was bitter. his hand, as he lifted it in his agony and let it fall again, struck against something hard in his pocket. thrusting it into the pocket, he felt there the sailor's knife which he had found in the hold of the ship, and drew it forth, regarding it. it was a good knife, he found himself reflecting, a good knife. the man who owned it had kept it in excellent order, too; sharp and keen. how he must have railed at losing it. and he, stephen, had found it! a good knife, long and stout-bladed, well pointed--a knife that would sever the stoutest cable or----! men had been slain with worse weapons than this. a blow from it over the heart, under the left shoulder, and struck downwards--yes! such blows must be struck downwards, or otherwise they might fail--and a life could easily be taken. easily--in a moment. it was a good knife, he thought again. as he opened it and ran his finger along its tapering blade, and observed the thick, solid back which that blade possessed, he could not but acknowledge this. the man who had owned it and lost it had paid money for that knife. this was no slop-shop thing bought of a thievish whitechapel or houndsditch jew who preyed on poor seamen. a good knife! he turned his head and looked at gilbert bampfyld lying there, still sleeping peacefully; looked at the man whom he had come out to seek, and--had found! found as he had never expected to do, as he had never believed it possible he should do. he looked at him, recognising all that his being there meant, all that this third human existence on the island, where formerly there had been but two persons, meant to him; the ruin that it cast upon his hopes. and again he regarded the knife, holding it by the tip, weighing it, balancing it. it _was_ a good knife; one that would strike hard and sure. and, as he so thought, he rose from his seat, went down to where the surf was beating violently now upon the beach, and flung the thing far off into the sea. then he returned to the sleeping man, and, kneeling by his side, shook his arm gently, saying: 'come, lieutenant bampfyld. come! wake up, rouse yourself.' chapter xxv i have loved my last, and that love was my first. 'my god!' exclaimed gilbert, as, beneath that light touch, he awoke and saw stephen charke by his side, 'is it a dream! you--you here! saved! thank god for all his mercies. i thought all were lost but me.' then, suddenly, even as he rose to his feet (limping on one of them, as charke saw, and grasping the tamarind cudgel he had cut himself as though for support), he cried, lifting his other hand to his eyes--'but, bella. oh, bella, my darling! are,' he added hoarsely, 'any others saved besides yourself? speak, put me out of my misery, one way or the other.' he saw, he must have seen, the answer in stephen charke's eyes, for now he fell down on the leaves and grass at his feet and clasped his hands as though thanking heaven fervently for its mercies. but he could not speak yet, nor for some moments, or only spoke to once more mutter incoherent words of thanksgiving for this last crowning mercy. 'yes,' charke said, and it seemed to himself as though his voice was tuneless, dead--as if it came from him with difficulty. 'yes, she is saved; is safe. and she hopes always to see you again.' 'but how? how? for god's sake, tell me that. she was in the cabin--surely she was in the cabin--i left her there when i struggled to the wheel. how was she saved?' 'i,' said charke, 'was enabled to help her. we got ashore together.' 'to help her!' gilbert said, looking into his eyes. 'to help her! it was more than that, i know. i am a sailor as well as you; such help is no light thing. should you not rather say you risked your life for hers? you could have done it in no other way.' 'no,' charke said, 'i risked nothing. it was nothing. any one could have done it.' again the other looked at him, knowing, feeling sure that the man before him was refusing to take any credit for what he had done. then he said: 'where is she? can i see her at once, now? soon?' 'she is not far. within two miles from here; she awaits, hopes for, your coming.' 'two miles! heaven help me! i can scarcely crawl. two miles, and i think my ankle is sprained.' 'she can come to you,' charke replied, and the deadness, the lack of tone in his voice, the lifelessness of it, was apparent to the listener now, as well as to himself. 'i can fetch her.' 'do! do! at once, i beseech you. oh to see her, to see my girl again. yet, still i do not understand. how could she hope to ever see me in life again, how await my coming? she could not dream, she could not dare to dream, that i might be saved.' 'she would not believe anything else. for myself,' charke went on, scorning to say that which was not the case, 'i did not believe you could be saved. it seems to me now, as you stand before me, that a miracle must have been worked in your behalf. and i told her so, mincing no matters. i told her you must be dead. but she would not believe. instead, she bade me, besought me to search this island, though, to be honest, i considered it useless to do so. yesterday i took the other side, to-day this. and she was right. i--have found you.' his tone was not aggressive, crisp and incisive though his words might be, yet there was something in the former, and, perhaps, the latter, which told gilbert bampfyld that the search he spoke of had been one of chivalrous obedience to a helpless woman's request, and not one made at his own desire. and he remembered how bella had told him this man had loved her once, and had hoped for her love in return. well, no matter, he had saved her at what must have been peril to his own life. he could not cavil at, nor feel hurt at, the coldness of his speech. 'what you have done,' he said, 'is more than words can repay; and, even though they were sufficient, now is not the time for them. mr. charke, can you bring her to me?' 'i will go at once. but--but she will, undoubtedly, be anxious, excited to know something of how you were saved. as we return to you she will desire to be told everything; will be impatient to hear. what shall i tell her, over and above the greatest news of all, that you are restored to her?' 'there is not much to tell. as i was swept over the ship's side my hand touched the port quarter-boat which was being thrown out at the moment.' 'ah! it has come ashore too.' 'and, naturally, i clutched at it. i would not let go; i held on like grim death, knowing that my only chance was in it. and, do you know, i found that i could see again; distinctly, or almost so. i could see the waves, the surf ahead; knew that some shore or coast was near. but, even as i recognised this, wondering, too, why at the moment when i was doomed to be drowned i should have this gift accorded me, i lost my hold on the boat and, a moment later, was thrown ashore or, at least, touched bottom. and--and it was a hard fight; i never thought to win through it. each recoil of the waves tore me back again only to find myself thrown forward with the next. three times it happened. then--then, at last, when i knew that, on the next occasion, i should have no breath left in my body, i was flung still farther on land than i had been before, and, this time, i determined i would not be dragged back alive, so i dug my foot and hands into the soft sand. i wrestled with those waves and i beat them. they receded, leaving me spread-eagled on the shingle, free of them for a moment, and, ere they could return and catch me again, i had scrambled out of their reach.' 'was that here, on this spot where we are now?' 'no, it was farther that way, between a mile and two miles farther.' and, as gilbert bampfyld spoke, he pointed with the stick in the direction where bella waldron and stephen charke had taken up their quarters since they had got ashore. therefore, her lover had been close to them once, and they had never known it! 'i stayed there one night,' gilbert went on, 'then feeling sure there were islands to the north--as there must be, you know--i came this way. only, i slipped on the beach and, i think, sprained my ankle, so that i could get no farther.' 'god has been very good to you,' stephen said, 'and to her. now i will go and bring her here: it will not take long. soon, very soon, you will be together. you will be happy. in a couple of hours she will be here. it would, perhaps, be in less time than that, only, you observe, the sea is rising and the surf getting very high. we must come inland, above, by the cliffs. farewell till then.' 'farewell. god bless you. ah, mr. charke, if you could only know my gratitude to you for saving her, also what happiness you have brought into my life again. if you could only know that!' but charke was on his way back to where he had left bella almost before gilbert had concluded his sentence, and, beyond a backward wave of his hand, had made no acknowledgment of his words. he climbed up to the summit of the cliffs easily enough, for by now all his strength had come back to him, and he felt as vigorous as he had ever done in his life. yet, when he gained the top, he noticed that there was still something wanting, some of the spring and elasticity which had characterised the manner in which he had returned to bella yesterday from the other side of the island. why was this, he asked himself? why? but he could find no answer to the question. yet, perhaps, his musings on what he had heard half an hour before were sufficient to have driven all the life, all the hope, out of him. his musings on the change that this last half-hour had brought into his future. god! his future. 'he was there, close to us,' he reflected, 'and we neither of us knew nor dreamt of it. i could have sworn it was impossible he should be saved. she--well, she did not dare to hope. and for two days! for two days he has been close to us, and--and in those two days what have i not pictured to myself, what dreams have i not had! what a fool's paradise i have been imagining for myself. now, there is nothing before me. nothing--now, or ever.' but still he forced himself to stride on, passing sometimes beneath the cocoa trees that grew on the little upland, sometimes through open glades in which the morning sun beat down upon his head with a fierceness only inferior to the strength it would assume an hour or so later--yet he heeded nothing. he felt that he must reach bella as soon as possible and tell her everything. there was no more joy left in existence for him, but he was the bearer of news that would give her joy extreme, and--he loved her. because he did so he would not keep that news from her one moment longer than was necessary. 'yet,' he whispered to himself, while thinking thus, 'she would have come to love me in his place some day, she would--she must. i divined it, saw it. now, it will never be. never. my god! it is a long word.' then he braced himself up still more and went on, until he stood upon the summit of the little elevation which rose behind the spot that they had made their resting-place. perhaps she had seen him returning; perhaps she had had some divination of his approach, since he perceived that she was coming towards him and was mounting the ascent to meet him, her head protected by the cap of the drowned sailor, while, over it, she held with one hand a great palm leaf to protect her from the sun. then, as they approached each other, she gave a gasp--it was almost a shriek, and cried out: 'mr. charke! mr. charke! what is the matter? what has happened? you are ghastly pale beneath your bronze. and--and your face is changed. what is it?' 'i come,' he said,--and now she gave another gasp, for his voice was changed too,--'as the bearer of good--of great tidings. of----, and he paused. for as he spoke she, too, had turned white. then, raising both her hands to her breast, she stood panting before him. 'he is saved!' she said. 'he is saved! gilbert is saved. is that it? are those the tidings?' 'yes,' he answered. 'yes. he is saved.' for a moment she stood before him, her hands still raised to her bosom, then, suddenly, she swayed forward and would have fallen but that he caught her in his arms, and, an instant later, had laid her on the soft grass, while he ran down to the rivulet to fetch some water to revive her. this happened directly after he had returned, but, when he had bathed her forehead and moistened her lips with the water, she soon sat up, saying: 'come, let us go to him. at once. we must go at once. yet--why does he not come to me?' 'he has hurt his foot. but it is nothing. only a sprain. if you are recovered from your swoon let us set out. it is not far. we shall be there soon.' whereon he gave her his hand and assisted her to rise, repeating that it was best to set out at once. and then they did so, he offering his arm to assist her up the slope, while explaining that, owing to the increased roughness of the sea, it was impossible to proceed by the beach to where her lover was. and, next, he began the account of how he found gilbert, and went through with it almost uninterruptedly, she listening without saying a word beyond now and again exclaiming, 'poor gilbert!' or 'thank god!' indeed, her silence during his narrative was such that more than once he glanced down at her, while wondering at that which seemed listlessness on her part. yet he would have wronged her deeply had he really believed her listless, since bella waldron would have been no true, honest, english girl had she by this time become indifferent to the news that her betrothed was saved. indeed, in her heart she was thanking god again and again, and far more often than she was giving outward utterance to those thanks, for having saved her lover and preserved him to her---only! only what? only, that she knew how, with their restored happiness, there had come to this other man--to him to whom she owed her life and, with it, the possibility of being once more united to gilbert--a broken heart and the destruction of every hope of happiness that he had cherished. she could see it in his face, hear it in his voice, discern it even by the manner in which he walked by her side. that which she knew he hoped for could never have been, she told herself; never, never, never! had gilbert died, still it could never have been; none could ever have taken his place. but, she was a woman with a true woman's heart in her breast--and her pity was womanly--sublime. chapter xxvi "here is my journey's end, here is my butt, and very seamark of my utmost sail." they had progressed so far towards the cliffs above the little bay or cove, where gilbert was, that now they had but to cross the summit of one more spur and then they would be able to descend to him. 'you will see him soon now,' charke said to the girl, 'very soon. then you will be happy. to-night, he and i will arrange the signals that may bring some succour to us. at any rate, it cannot be long in coming. if we are where i think, hundreds of ships pass near here annually. and, at the worst, one may live here very well for some time.' she heard his words, she missed no tone nor inflection of his voice--but she could not answer him. it was impossible. for, though he spoke on subjects which were appropriate enough to their surroundings, she knew that his speech, instead of conveying his thoughts, was only used to hide them; and that beneath what he said lay a sadness too deep for utterance. therefore, she made no attempt at reply, but contented herself with letting her eyes rest on his face now and again, and then withdrawing them directly afterwards. suddenly, however, and after having cast a glance backwards across the little plateau which they had passed along, he exclaimed: 'why, lieutenant bampfyld will find another companion of his in the poor old _emperor_ here to greet him. see, there comes bengalee, behind us. how has he broken away from the cable? it was stout enough to hold a small frigate,' and, as she turned to look in the direction he had indicated, she saw the tiger-cub coming after them along the plateau at a considerable pace. coming swiftly, too, and always with the lithe and hateful sinuosity which marks the progress of the species. then, as she, too, turned and saw its striped body winding in and out beneath the tamarind and palm trees, she remembered that she had observed it gnawing at the cable ere she set out, and told stephen so. and she also told him that it had seemed much excited at being left behind, and had made considerable struggles to break loose when she moved away. 'it will perhaps be appeased,' he answered, 'when it finds itself once more with you. poor wretch! its hunger must be frightful. yet--yet--how else to kill it? and killed it must be.' 'i wish,' she said again, as she had so often said before, 'that i had never asked to have it saved. it would have been better to have let it die in the sea.' 'perhaps,' he answered. 'perhaps. we can, however, leave it here when we get taken off, and then it must take its chance.' they were now upon the last ridge of the spur beneath which he had left gilbert, and he told her that, in another moment, she would see him by looking down. 'indeed,' he said, 'if you glance over now you can see him, i imagine.' then he bade her hold his hand and lean over the lip of the precipice, and trace the run of the hill seawards. following his instructions, she did so, when suddenly, below, they heard a rattling, a sliding as of a mass of earth and stones slipping, and he felt a slight withdrawal, a sinking of the ground, beneath their feet. he felt it and understood its significance in an instant, while recalling the masses of fallen chalk and earth which he had observed lying at the foot of this and other cliffs earlier in the day. 'back,' he cried, 'back!' while, as he did so, he seized bella with his other hand as well as the one she already held, and sprang away from the ridge, the violence of his action causing her to fall on her knees. yet, still knowing her danger--their danger--he dragged her back and saved her. though not a moment too soon--not an instant!--for, as he clutched at her, the earth for a foot or so in front of them--the very portion of it on which they had been standing! the very portion, indeed, across which he had but now drawn her--gave way. it gave way, broke off in a long line, and fell with a crash to the depths below, leaving an abyss above the spot over which he had drawn her. 'my god!' she gasped, 'you have saved my life again! again--ah!' that last exclamation was, in truth, a shriek of dismay, of awful agony, of terror in the extreme. for she, whose face was towards the way they had come, as his back was towards it, saw that which he had no knowledge of; that which paralysed her, struck her an instant after dumb with horror. she saw the tiger-cub close behind him and crouching for a spring, she saw its devilish eyes gleaming like topazes, and she saw its body hurled with tremendous force towards charke as he stood looking down on her. full at him it sprang, its savage jaws open and its forelegs extended. and it partly missed him through passing on his left side, yet not doing so altogether. instead, it struck his left shoulder, spinning him round like a drunken, reeling man, and causing him to stagger backwards towards the chasm and, with a gasp, to fall over it and disappear. and bella, left alone in that awful moment--for the tiger's leap had carried it far over the cliff and to its own destruction--saw a man below--her lover--shouting and gesticulating--and then she knew no more. * * * * * * an hour later, stephen charke lay on his back below the cliff, his eyes upturned to the sun, which was by now peeping over the hill and illuminating all the little valley with its rays--he lay there breathing his last and with his back broken. by his side knelt bella waldron, while gilbert bampfyld stood near, their faces the true index of their sorrow. 'no,' stephen whispered hoarsely, now, in answer to a question from her. 'no. i feel no pain, nothing but the numbness of my back and lower limbs. nay, nay, do not weep.' then he lowered the poor, feeble voice a little more and whispered even more calmly to her--'i am content, well content. and--it--is better so. there was no life, no future for me.' 'oh!' she said, wringing her hands while the tears streamed from her eyes and dropped upon his upturned face. 'oh! that you should have died in saving me. that you, whom i honour so, should die at all--young, strong, as you are. and through the outcome of my wilfulness, of my letting that creature be saved. saved to slay you. ah! god, it is too hard!' 'it thought,' he said, after a pause, during which she wiped the drops from his forehead and moistened his lips, 'that i was attacking you. doubtless it did so. it hated me and loved you.' then, he added to himself, 'as all love you.' 'gilbert,' she shrieked now to her lover, 'gilbert, can nothing be done; nothing to save him? ah! perhaps his back is not broken; it may be but a terrible fall--he may recover yet. can we do nothing?' but it was stephen who answered, 'nothing.' 'old chap,' said gilbert, also close by him now, and kneeling down to take his hand, 'is--is there anything you want done; any message sent to any one at home? only say the word. you know you can depend on me.' 'if it can be,' the dying man said, and now his voice was very low, almost inaudible, 'if you can have it done later, when you are found, bury me--at--the--spot where she and i--came ashore. there, in the little knoll. you know.' and his eyes sought hers. 'that is where i want--to lie--until we meet again.' they could not answer him, their voices were no longer their own; hardly could they see him through their tears, but still they were able to tell him by their gestures that it should be as he desired. after which gilbert managed to rise to his feet and whisper in bella's ears, 'he is--going--now. the end is close at hand. say--say "goodbye" to him, and--and kiss him. he deserves it from you, and--i shall not grudge it.' then, in his manliness, he turned away from them. perhaps the dying man guessed what had been said; and, because he knew his hour had come, he opened his eyes for the last time and gazed wistfully at her. 'goodbye,' he said. 'farewell.' 'goodbye. oh, god! that i should have to say it to you. goodbye--goodbye, stephen,' and she stooped down and kissed the cold, white lips of the man who had loved her so. and, next, she put her arm beneath his neck and let his head lie on it, while, amidst the tempest of her sobs, she heard him murmur feebly: 'i loved you--from--the first--moment. i love--you--now.' then his head turned over on her arm and lay there motionless. * * * * * * the wedding was over, gilbert bampfyld and bella were man and wife, the marriage having taken place at capetown. while the only difference between the ceremony and that which had been originally intended was that the archbishop of capetown joined their hands instead of the bishop of bombay doing so. therefore, at last, these two loving hearts were made happy, and, in spite of all that had threatened both bella and her lover during the past few months, the future now looked bright and cheerful. not three days had elapsed since stephen charke's death when gilbert (who, with bella, sat from sunrise to sunset beneath a clump of cocoa trees on the highest point to which they could attain, he being soon able to reach it quite easily by the aid of his cudgel and owing to the rapid improvement in the sprain he had suffered from) saw a vessel not two miles away from the island. 'and i swear,' he exclaimed, 'one of her majesty's cruisers. look at those yellow funnels, one aft of the other. that's a cruiser right enough. i wonder if it's the _briseus_.' then he fell to making every kind of signal which he could devise when unprovided with the means of attracting her attention either by pistol-shot or fire, and in about half an hour they had the joy of seeing one of her cutters manned and lowered, and, a moment later, making for the shore. the cruiser turned out to be the _clytie_, on her way home from calcutta to plymouth, and, even as the cutter fetched the shore, the coxswain recognised gilbert as an officer with whom he had previously served. then he furnished him with the intelligence that he was reported dead. 'not yet,' said gilbert; 'though, since i left the _briseus_, when in charge of her whaler, i have had two narrow escapes. unfortunately, others, with whom i have been in company, are so.' then, briefly, he told the man all that had happened to him, and stated that he was going to ask the captain of the _clytie_ for a passage for himself and his future wife, the young lady by his side. first, however, there was one thing to be done--namely, to bury stephen charke in the place which he had indicated. this was a thing which would now be very easy of accomplishment, since the sea was perfectly calm again and the body could be easily carried from the spot where he had fallen to that where he desired to be buried. but, to begin with, the permission of the captain had to be obtained, which was done by signalling, and then the rest was easy. some more men were sent off in the second cutter, with the chaplain as well as some spades for digging a grave, after which the sailors marched under gilbert's command to where he and bella had covered up stephen charke's remains with palm and other leaves that were within their reach, and then removed the body. and very reverently was the interment performed, all standing round the spot with the exception of bella, who was so overcome that she had to be led away from the grave. and so they laid him in it; and there, in the little solitary island, they left him to his long sleep. perhaps, nothing so much as his death--not even his heroism in the stricken ship, nor his masterful strength in fighting the storm and the waves, and in succeeding at the risk of his own life in saving that of the woman whom he so tenderly loved--kept his memory green in both their hearts. perhaps, too, that last sacrifice which he made--his life!--at the moment when once more he was preserving hers, furnishes the reason which again and again prompts gilbert to say to his wife, in a voice always full of a tone of regret for the brave man who lies so far away: 'after all, bella, i am not sure that you chose the right one. poor stephen charke was the better man of the two.' yet, when he observes the glance she gives him in return, he is comforted by knowing that, in no circumstances, could that other have ever won her heart as he did. footnotes [footnote 1: this is not fictitious. m. constant made his speech to the

1912, 1920, by c. v. mosby company _press of c. v. mosby company st. louis_ to my mother this volume is affectionately dedicated preface to third edition several years have elapsed since the appearance of the second edition of this book. during this time there has been considerable experimentation and much writing on arteriosclerosis. the total of all work has not been to add very much to our knowledge of the etiology of arterial degeneration. points of view and opinions change from time to time. it is so with arteriosclerosis. in this edition arteriosclerosis is not regarded as a disease with a definite etiologic factor. rather it is looked upon as a degenerative process affecting the arteries following a variety of causes more or less ill defined. it is not considered a true disease. possibly syphilitic arteritis may be viewed as an entity, the cause is known and the lesions are characteristic. much new material and many new figures have been added to this edition. some rearranging has been done. the chapter on blood pressure has been much expanded and some original observations have been included. the literature has been selected rather than indiscriminately quoted. much that is written on the subject is of little value. it has always seemed to the author that there is not enough of the personal element in medical writings. at the risk of being severely criticized, he has attempted to make this book represent largely his own ideas, only here and there quoting from the literature. new chapters on cardiac irregularities associated with arteriosclerosis, and blood pressure in its clinical application have been added. the fact that the book has passed through two editions is very gratifying and seems to show that it has met with favor. the author takes this opportunity of thanking those who have loaned him illustrations. wherever figures are borrowed due credit is given. it is hoped that the kind of reception accorded to the first and second editions will also not be withheld from this present edition. louis m. warfield. milwaukee, wisc. preface to the second edition in this second edition so many changes and additions have been made that the book is practically a new one. all the chapters which were in the previous edition have been carefully revised. two chapters, "pathology" and "physiology," have been completely rewritten and brought up to date. it was thought best to add some references for those who had interest enough to pursue the subject further. these references have been selected on account of the readiness with which they may be procured in any library, public or private. two new chapters have been added--one on "the physical examination of the heart and arteries," the other on "arteriosclerosis in its relation to life insurance," and it is hoped that these will add to the practical value of the book. arteriosclerosis can scarcely be considered apart from blood pressure, and in the view expressed within, with which some may not concur, high tension is considered to be a large factor in the production of arteriosclerosis. as the data on blood pressure have increased, the importance of it has become more evident. the chapter on "blood pressure" has been wholly rewritten, expanded so as to give a comprehensive grasp of the essential features, and several illustrations have been added in order to elucidate the text more fully. the chief objects in view were to make clear to the physician the technique and the necessity for estimating both systolic and diastolic pressures. the author is grateful for the kindly reception accorded the first edition. no one is more keenly aware of the imperfections than he. the necessity for a second edition is taken to mean that the book has found a place for itself and has been of use to some. the author hopes that this new edition will fulfill adequately the purpose for which he prepared the book--namely, as a practical guide to the knowledge and appreciation of a most important and exceedingly common disease. louis m. warfield. milwaukee, may, 1912. preface to the first edition it is hoped that this small volume may fill a want in the already crowded field of medical monographs. the author has endeavored to give to the general practitioner a readable, authoritative essay on a disease which is especially an outcome of modern civilization. to that end all the available literature has been freely consulted, and the newest results of experimental research and the recent ideas of leading clinicians have been summarized. the author has supplemented these with results from his own experience, but has thought it best not to burden the contents with case histories. the stress and strain of our daily life has, as one of its consequences, early arterial degeneration. there can be no doubt that arterial disease in the comparatively young is more frequent than it was twenty-five years ago, and that the mortality from diseases directly dependent on arteriosclerotic changes is increasing. fortunately, the almost universal habit of getting out of doors whenever possible, and the revival of interest in athletics for persons of all ages, have to some extent counteracted the tendency to early decay. nevertheless, the actual average prolongation of life is more probably due to the very great reduction in infant mortality and in deaths from infectious and communicable diseases. the wear and tear on the human organism in our modern way of living is excessive. hard work, worry, and high living all predispose to degenerative changes in the arteries, and so bring on premature old age. the author has tried to emphasize this by laying stress on the prevention of arteriosclerosis rather than on the treatment of the fully developed disease. no bibliography is given, as this is not intended as a reference book, but rather as a guide to a better appreciation and understanding of a most important subject. it has been difficult to keep from wandering off into full discussions of conditions incident to and accompanied by arteriosclerosis, but, in order to be clear in his statements and complete in his descriptions, the author has to invade the fields of heart disease, kidney disease, brain disease, etc. it is hoped, however, that these excursions will serve to show how intimately disease of the arteries is bound up with diseases of all the organs and tissues of the body. some authors have been named when their opinions have been given. thanks are extended also to many others to whom the writer is indebted, but of whom no individual mention has been made. the author also takes this opportunity of expressing his appreciation of the kindness of dr. d. l. harris, who took the microphotographs, and to the publishers for their unfailing courtesy and consideration. louis m. warfield. st. louis, august, 1908. contents page chapter i anatomy 25

increased wear and tear on the human organism. "a man is as old as his arteries" is an old dictum, and, like many proverbs, the application to mankind today is, if anything, more pertinent than it was when the saying was first uttered. notwithstanding the fact that the average age of mankind at death has been materially lengthened--the increase in years amounting to fourteen in the past one hundred years of history--clinicians and pathologists are agreed that the arterial degeneration known as arteriosclerosis is present to an alarming extent in persons over forty years of age. figures in all vital statistics have shown us that all affections of the circulatory and renal systems are definitely on the increase. "arterial diseases of various kinds, atheroma, aneurysm, etc., caused 15,685 deaths in 1915, or 23.3 per 100,000. this rate, although somewhat lower than the corresponding ones for 1912 and 1913, is higher than that for 1914, and is very much higher than that for 1900, which was 6.1." the great group of cases of which cardiac incompetence, aneurysm, cerebral apoplexy, chronic nephritis, emphysema, and chronic bronchitis are the most frequent and important appear as terminal events in which arteriosclerosis has probably played an important part. thus, in the sense in which we speak of tuberculosis or pneumonia as a distinct disease, we can not so designate the diseased condition of the arteries. arteriosclerosis is not a disease =sui generis=. it is best viewed as a degeneration of the coats of the arteries, both large and small resulting in several different more or less distinct types. these types blend one into the other and in the same patient all types may be found. thus the sclerosis of the arteries is the result of a variety of causes, none of which is definitely known in the sense of a bacterial disease. as we shall see later, one type of arteriosclerosis has a special pathology and etiology, the syphilitic arterial changes. bearing in mind that arteriosclerosis (called by some "arteriocapillary fibrosis," by others "atherosclerosis") is not a true disease, it may, for convenience be defined as a chronic disease of the arteries and arterioles, characterized anatomically by increase or decrease of the thickness of the walls of the blood vessels, the initial lesion being a weakening of the middle layer caused by various toxic or mechanical agencies. this weakness of the media leads to secondary effects, which include hypertrophy or atrophy of the inner layer--and not infrequently hypertrophy of the outer layer--connective tissue formation and calcification in the vessels, and the formation of minute aneurysms along them. the term arteriocapillary fibrosis has a broader meaning, but is a cumbersome phrase, and conveys the idea that the capillary changes are an essential feature of the process, whereas these are for the most part secondary to the changes in the arteries. the veins do not always escape in the general morbid process, and when these are affected the whole condition is sometimes called vascular sclerosis or angiosclerosis. upon the anatomical structure of the arteries depends, as a rule, the character and extent of the arteriosclerotic lesions. for the clear comprehension of the process, it is necessary to keep in mind the essential histological differences between the aorta and the larger and smaller branches of the arterial tree. the vascular system is often likened to a central pump, from which emanates a closed system of tubes, beginning with one large distributing pipe, which gives rise to a series of tubes, whose number is constantly increasing at the same time that their caliber is decreasing in size. from the smallest of these tubes, larger and larger vessels collect the flowing blood, until, at the pump, two large trunks of approximately the same area as the one large distributing trunk empty the blood into the heart, thus completing the circle. this is but a rough illustration, and, while possibly useful, takes into account none of the vital forces which are constantly controlling every part of the distributing system. general structure of the arteries the aorta and its branches are highly elastic tubes, having a smooth, glistening inner surface. when the arteries are cut open, they present a yellowish appearance, due to the large quantity of elastic tissue contained in the walls. the elasticity is practically perfect, being both longitudinal and transverse. the essential portion of any blood vessel is the endothelial tube, composed of flat cells cemented together by intercellular substance and having no stomata between the cells. this tube is reinforced in different ways by connective tissue, smooth muscle fibers, and fibroelastic tissue. although the gradations from the larger to the smaller arteries and from these to the capillaries and veins are almost insensible, yet particular arteries present structural characters sufficiently marked to admit of histological differentiation. the whole vascular system, including the heart, has an endothelial lining, which may constitute a distinct inner coat, the tunica intima, or may be without coverings, as in the case of the capillaries. the intima (fig. 1) consists typically of endothelium, reinforced by a variable amount of fibroelastic tissue, in which the elastic fibers predominate. the tunica media is composed of intermingled bundles of elastic tissue, smooth muscle fibers, and some fibrous tissue. the adventitia or outer coat is exceedingly tough. it is usually thinner than the media, and is composed of fibroelastic tissue. this division into three coats is, however, somewhat arbitrary, as in the larger arteries particularly it is difficult to discover any distinct separation into layers. [illustration: fig. 1.--cross section of a large artery showing the division into the three coats; intima, media, adventitia. the intima is a thin line composed of endothelial cells. the wavy elastic lamina is well seen. the thick middle coat is composed of muscle fibers and fibroelastic tissue. the loose tissue on the outer (lower portion of cut) side of the media is the adventitia. (microphotograph, highly magnified.)] the muscular layer varies from single scattered cells, in the arterioles, to bands of fibers making up the body of the vessel in the medium-sized arteries and veins. there is elastic tissue in all but the smallest arteries, and it is also found in some veins. it varies in amount from a loose network to dense membranes. in the intima of the larger arteries the elastic tissue occurs as sheets, which under the microscope appear perforated and pitted, the so-called fenestrated membrane of henle. the nutrient vessels of the arteries and veins, the vasa vasorum, are present in all the vessels except those less than one millimeter in diameter. the vasa vasorum course in the external coat and send capillaries into the media, supplying the outer portion of the coat and the externa with nutritive material. the nutrition of the intima and inner portion of the media is obtained from the blood circulating through the vessel. lymphatics and nerves are also present in the middle and outer layers of the vessels. arteries the structure of the arteries varies notably, depending upon the size of the vessel. a cross section of the thoracic aorta reveals a dense network of elastic fibers, occupying practically all of the space between the single layer of endothelial cells and the loose elastic and connective tissue network of the outer layer. smooth muscle fibers are seen in the middle coat, but, in comparison with the mass of elastic tissue, they appear to have only a limited function. in a cross section of the radial artery one sees a wavy outline of intima, caused by the endothelium following the corrugations of the elastica. the endothelium is seen as a delicate line, in which a few nuclei are visible. the media is comparatively thick, and is composed of muscle cells, arranged in flat bundles, and plates of elastic tissue. between the media and the externa the elastic tissue is somewhat condensed to form the external elastic membrane. the adventitia varies much in thickness, being better developed in the medium-sized than in the large arteries. it is composed of fibrous tissue mixed with elastic fibers. "followed toward the capillaries, the coats of the artery gradually diminish in thickness, the endothelium resting directly upon the internal elastic membrane so long as the latter persists, and afterward on the rapidly attenuating media. the elastica becomes progressively reduced until it entirely disappears from the middle coat, which then becomes a purely muscular tunic, and, before the capillary is reached, is reduced to a single layer of muscle cells. in the precapillary arterioles the muscle no longer forms a continuous layer, but is represented by groups of fiber cells that partially wrap around the vessel, and at last are replaced by isolated elements. after the disappearance of the muscle cells the blood vessel has become a true capillary. the adventitia shares in the general reduction, and gradually diminishes in thickness until, in the smallest arteries, it consists of only a few fibroelastic strands outside the muscle cells." (piersol's anatomy.) the large arteries differ from those of medium size mainly in the fact that there is no sharp line of demarcation between the intima and the media. there is also much more elastic tissue distributed in firm bundles throughout the media, and there are fewer muscle fibers, giving a more compact appearance to the artery as seen in cross section. the predominance of elastic tissue permits of great distention by the blood forced into the artery at every heartbeat, the caliber of the tube being less markedly under the control of the vasomotor nerves than is the case in the small arteries, where the muscle tissue is relatively more developed. the adventitia of the large arteries is strong and firm, and is made up of interlacing fibroelastic tissue, of which some of the bundles are arranged longitudinally. veins the walls of the veins are thinner than those of the arteries; they contain much less elastic and muscular tissue, and are, therefore, more flaccid and less contractile. many veins, particularly those of the extremities, are provided with cup-like valves opening toward the heart. these valves, when closed, prevent the return of the blood to the periphery and distribute the static pressure of the blood column. the bulgings caused by the valves may be seen in the superficial veins of the arm and leg. there are no valves in the veins of the neck, where there is no necessity for such a protective mechanism, gravity sufficing to drain the venous blood from the cranial cavity. capillaries these are endothelial tubes in the substance of the organs, the tissue of the organ giving them the necessary support. they are the final subdivisions of the blood vessels, and the vast capillary area offers the greatest amount of resistance to the blood flow, thus serving to slow the blood stream and allowing time for nutritive substances or waste products to pass from and to the blood. usually the capillaries are arranged in the form of a network, the channels in any one tissue being of nearly uniform size, and the closeness of the mesh depending upon the organ. as far back as 1865, stricker observed contraction of the capillaries. this observation was apparently forgotten until revived again by krogh recently. the latter finds that the capillaries are formed of cells which are arranged in strands encircling the vessel. the capillaries are rarely longer than 1 mm., and, according to krogh, are capable of enormous dilatation. the rate of flow through any capillary area is very inconstant, and the usual explanation has been that the capillaries were endothelial tubes the blood flow of which was dependent upon the contraction or dilatation of the terminal arterioles. the actual fact that in an observed capillary area some capillaries are empty renders the above explanation untenable. the color of a tissue depends upon the state of filling of the capillaries with blood. it would seem that all the evidence now leads us to believe that the capillaries themselves are contractile and it is even possible that they may be under vasomotor control. if the anatomic structure as stated above, is correct, it would take but a slight contraction of the encircling cell to shut off completely the capillary. when the enormous capillary bed is considered, it is not inconceivable that circulating poisons may act on large areas and produce a true capillary resistance to the onflow of blood which might express itself, if long continued, in actual hypertrophy of the heart. chapter ii pathology the whole subject of the pathology of arteriosclerosis has been much enriched by the study of the experimental lesions produced by various drugs and microorganisms upon the aortas of rabbits. simple atheroma must not be confused with the lesions of arteriosclerosis. the small whitish or yellowish plaques so frequently seen on the aorta and its main branches, may occur at any age, and have seemingly no great significance. such plaques may grow to the size of a dime or larger, and even become eroded. they represent fatty degeneration of the intima which, at times, has no demonstrable cause; at times follows in the course of various diseases, and undoubtedly is due to disturbances of nutrition in the intima. except for the remote danger of clot formation on the uneven or eroded spot, these places are of no special significance, and are not to be confused with the atheroma of nodular sclerosis. the lesions of arteriosclerosis are of a different character. it has been customary to differentiate three types: (1) nodular; (2) diffuse; (3) senile. it must be understood that this is not a classification of distinct types. as a rule in advanced arteriosclerosis, lesions representing all types and all grades are found. the nodular type, however, may occur in the aorta alone, the branches remaining free. this is most often found in syphilitic sclerosis where the lesion is confined to the ascending portion of the arch of the aorta. the retrogressive changes of advancing years can not be rightly termed disease, yet it becomes necessary to regard them as such, for the senile changes, as we shall see, may be but the advanced stages of true arteriosclerosis. much depends on the nature of the arterial tissue and much on the factors at work tending to injure the tissue. a man of forty years may therefore have the calcified, pipe stem arteries of a man of eighty. our parents determine, to great extent, the kind of tissue with which we start life. the arteries are elastic tubes capable of much stretching and abuse. in the aorta and large branches there is much elastic tissue and relatively little muscle. when the vessels have reached the organs, they are found to be structurally changed in that there is in them a relatively small amount of elastic tissue but a great deal of smooth muscle. this is a provision of nature to increase or decrease the supply of blood at any point or points. the aorta and the large branches are distributing tubes only. it is after all in the arterioles and smaller arteries that the lesions of arteriosclerosis do the most damage. a point to be emphasized is that the whole arterial system is rarely, if ever, attacked uniformly. that is, there may be a marked degree of sclerosis in the aorta and coronary arteries with very little, if any, change in the radials. on the contrary, a few peripheral arteries only may be the seat of disease. a case in point was seen at autopsy in which the aorta in its entirety and all the large peripheral branches were absolutely smooth. in the brain, however, the arteries were tortuous, hard, and were studded with miliary aneurysms. it is not possible to judge accurately the state of the whole arterial system by the stage of the lesion in any one artery; but on the whole one may say that an undue thickening of the radial artery indicates analogous changes in the mesenteric arteries and in the aorta. so far as the anatomical lesions in the aorta and branches are concerned, there is much uniformity even though the etiologic factors have been diverse. the only difference is one of extent. to thoma we owe the first careful work on arteriosclerosis. he regarded the lesion in arteriosclerosis as one situated primarily in the media; there is a lack of resistance in this coat. his views are now chiefly of historical interest. as the author understands him, he considered a rupture in the media to be the cause of a local widening and consequently the blood could not be distributed evenly to the organ which was supplied by the diseased artery or arteries. moreover, there was danger of a rupture at the weak spot unless this were strengthened. it was essential for the even distribution of blood that the lumen be restored to its former size. nature's method of repair was a hypertrophy of the subintimal connective tissue and the formation of a nodule at that point. the thickening was compensatory, resulting in the establishment of the normal caliber of the vessel. thoma showed that by injecting an aorta in the subject of such changes, with paraffin at a pressure of 160 mm. of mercury, these projections disappeared and the muscle bulged externally. he recognized the fact that the character of the artery changed as the years passed, and to this form he gave the name, primary arteriosclerosis. to the group of cases caused by various poisonous agents, or following high peripheral resistance and consequent high pressure, he gave the name, secondary arteriosclerosis. this is a useful but not essential division, as the changes which age and high tension produce may not be different from those produced in much younger persons by some circulating poison. and most important to bear in mind, octogenarians may have soft, elastic arteries. as the body ages, certain changes usually take place in the arteries leading to thickening and inelasticity of their walls. this is a normal change, and in estimating the palpable thickening of an artery, such as the radial, the age of the individual must always be considered. thayer and fabyan, in an examination of the radial artery from birth to old age, found that, in general, the artery strengthens itself, as more strain is thrown upon it, by new elastica in the intima and connective tissue in the media and adventitia. up to the third decade there is only a strengthening of the media and adventitia. during the third and fourth decades there is also distinct connective tissue thickening in the intima. "in other words, the strain has begun to tell upon the vessel wall, and the yielding tube fortifies itself by the connective tissue thickening of the intima and to a lesser extent of the media." by the fifth decade the connective tissue deposits in the intima are marked, there is an increase of fibrous tissue upon the medial side of the intima and, in lesser degree, throughout the media. "finally, in these sclerotic vessels degenerative changes set in, which are somewhat different from those seen in the larger arteries, consisting, as they do, of local areas of coagulation necrosis with calcification, especially marked in the deep layers of the connective tissue thickenings of the intima, and in the muscle fibers of the media, particularly opposite these points. these changes may ... go on to actual bone formation." the mesenteric artery differs in some respects from the radial, but in the main, the changes brought about by age are the same. thayer and fabyan note two striking points of difference: "(1) calcification is apparently much less frequent than in the radials; (2) in several cases plaques were seen with fatty softening of the deeper layers of the intima and superficial proliferation--a picture which we have never seen in the radial." (see fig. 2.) [illustration: fig. 2.--cross-section of a coronary artery, x50, showing nodular sclerosis. note the heaping up of cells in the intima, the fracture of the elastica, and the destruction of the media beneath the nodule. the primary lesion evidently was in the media. the thickened intima is the effort on the part of nature to heal the breach. at such places as shown here aneurysms may form. (microphotograph.)] aschoff's studies of the aorta show that, "in infancy the elastic lamin㦠of the media stand out sharply defined, well separated from each other by the muscle layers, which are well developed.... from childhood there is to be observed a slowly progressive increase in the elastic elements of the media. not only do the individual lamell㦠seen in cross-sections become thicker, but also they afford an increasing number of fine secondary filaments feathering off from these and crossing the muscle layer, so that now they are no longer sharply defined, but more ragged upon cross-section. this progressive increase attains its maximum at or about the age of thirty-five, and from now on for the next fifteen years the condition is relatively stationary. after fifty there is to be observed a slowly progressive atrophy of the elastica. the media becomes obviously thinner and presumably weaker." (adami.) it has also been found (klotz) that after the age of thirty-five, the muscle of the media begins to exhibit fatty degeneration which after fifty years is well marked. the fatty degeneration may then give place to a calcareous infiltration or the fibers may undergo complete absorption. it would appear that the thinning of the aortic media is due not so much to the atrophy of the elastic tissue as to that of the muscle tissue. the elastic tissue does lose its specific property and the artery thus becomes practically a connective tissue tube. scheel has made very careful measurements of the ascending, the thoracic, and the abdominal aorta, and the pulmonary artery. he found that from birth to sixty years, the aorta became progressively wider and lost its elasticity. the pulmonary changed little, if at all, after thirty to forty years, and where before it was wider than the aorta, it now was found to be smaller. in chronic nephritis both were widened. the continuous increase of width and length of the aorta stands in reverse relationship to the elasticity of its walls. although the division of the lesions into nodular, diffuse, and senile has been the usual one, it is better to separate three groups into (1) nodular, (2) diffuse or senile, and (3) syphilitic. there is more known about the histology of the syphilitic form and the lesions which consist of puckerings and scars seen on opening an aorta just above the valves, and on the ascending portion of the arch are characteristic. a macroscopic examination suffices in most cases for a definite diagnosis. in the nodular form the lesions are found on the aorta and large branches particularly at or near the orifices of branching vessels. these nodules may increase in size, forming rather large, slightly raised plaques of yellowish-white color. they are, as a rule, irregularly scattered throughout the aorta and branches and tend to be more numerous and larger in the abdominal aorta. the initial lesion is in the media, consisting of an actual dissolution of this coat with rupture of the elastic fibers and infiltration with small round cells. there is thus a weak spot in the artery. hypertrophy of the intimal cells takes place, layer upon layer being added in an attempt to strengthen the vessel at the injured place. coincidently with this, there is thickening by a connective tissue growth in the adventitia. the process begins, at least in syphilis, around the terminals of the vasa vasorum. it will be recalled that the blood supply of the inner portion of the media comes from within the vessel itself. as the intimal growth increases, the blood supply is cut off. the inevitable result is softening of the portion farthest from the lumen of the vessel. as a rule there has been a sufficient growth of connective tissue in the media and adventitia to repair the damage done to the media. this softening and dissolution gives rise to a granular debris composed of degenerated cells and fat. this is the so-called atheromatous abscess. there are no leucocytes as in ordinary pus. these "abscesses" are frequent and in rupturing leave open ulcers with smooth bases, the atheromatous ulcer. a further change which often takes place is calcification of the bases of the ulcers and calcification of the softened spots before rupture takes place. this only occurs in advanced cases. (see fig. 3.) [illustration: fig. 3.--arteriosclerosis of the thoracic and abdominal aorta, showing irregular nodules, atheromatous plaques, denudation of the intima, thin plates of bone scattered throughout with spicules extending into the lumen of the vessel. note the contraction of the openings of the large branches, the rough appearance of the aorta and the greater degree of sclerosis of the upper two-thirds, i. e., of the aorta above the diaphragm. this aorta in the recent state was much thickened and almost inelastic.] [illustration: fig. 4.--arteriosclerosis of the arch of the aorta. numerous calcified plaques, thickening and curling of the aortic valves, giving rise to insufficiency of the aortic valves. the aortic ring is rigid and not much dilated. (milwaukee county hospital.)] [illustration: fig. 5.--normal aorta. compare with fig. 3. note the perfectly smooth, glossy appearance of the intima. the openings of all the intercostal arteries are distinctly seen. in the recent state this artery was highly elastic, capable of much stretching both transversely and longitudinally.] rather contrary to what one would expect, there are no new capillaries advancing from the media to the intima in the nodular form of arteriosclerosis, consequently there is no granulation tissue to heal and leave scars. it must be borne in mind that these changes rarely, if ever, are the only ones found throughout the arterial system. nevertheless, the manifold changes, as will be shown within, appear to be but stages of one primary process. the character of the changes which are known as diffuse arteriosclerosis seems to have, at first sight, little in common with those of the nodular sclerosis. the aorta may or may not have plaques of nodular sclerosis, while the arteries, such as the radial or temporal, may be beaded or pipe stem in hardness. in spite of these far advanced peripheral lesions the aorta may appear smooth but it is markedly dilated, particularly the thoracic portion, it is noticeably thinned even on macroscopic examination, it has elongated as evidenced by its slight tortuosity, and it has lost the greater part of its elasticity. the abdominal aorta is not so extensively affected, although this, too, shows some elongation and slight thinning. this is considered by some pathologists to be the uncomplicated form of the so-called senile arteriosclerosis. it is more of the nature of a degenerative change, it is true, but, as will be shown later, it has its beginnings, at times, in comparatively young persons and its etiology is not simple. this type has been studied most carefully by moenckeberg, who showed that on the large branches of the aorta there were depressions due to a degeneration of the middle coat. these depressions encircled the vessel to a greater or lesser extent, causing small bulgings at such places and giving to the vessel a beaded appearance. on viewing such an artery held to the light, the sacculated spots are seen to be much thinner than the contiguous normal artery. associated with such changes in the aorta and large branches is marked sclerosis of the smaller arteries. intimal fibrosis is common, together with hypertrophy and fibrosis of the middle coat. not infrequently periarterial thickening is also seen. calcification of the media is found and is said to be preceded by hypertrophy of the middle coat. pure cases of this, the so-called moenckeberg type, are seen but seldom. most commonly there are nodules and plaques in the aorta and large branches together with thinning and sacculation of other portions of the vessels' walls. while the two processes appear at a glance to be so different from each other, it is possible for them to have a common origin. the initial lesion is in the media but the resulting sclerotic changes depend upon the kind of vessel, the strength of the coats, the pressure in the vessel, and other causes. thus the sclerosis of the radials of such an extent that these arteries are easily palpable, appears to be a different process from that of the sclerosis in the aorta, yet fundamentally it is the same. the difference lies in the anatomic structure of the two vessels, and possibly also in the degree of stretching and strain to which the vessels are subjected at every heart beat. in the radial artery the media as usual is affected first. the muscle cells undergo degeneration and either marked thickening takes place or sacculation results, depending upon the severity of the exciting cause. calcification of the media is common. this occasionally takes the form of rings encircling the vessel, and gives to the examining finger the sensation of feeling a string of fine beads. there may be calcification of the subintimal tissue without deposits of lime salts in the media, but this is more commonly found in the larger arteries. when the calcification occurs in plates through the media, the well known pipe stem vessel is produced. (fig. 6.) [illustration: fig. 6.--radiogram of a man aged seventy-five, showing calcification of both radial and ulnar arteries.] the senile sclerosis found in old people is usually a combination of the moenckeberg type in the large and medium-sized arteries, and the nodular type in the aorta, leading eventually to calcareous intimal deposits, and widened, elongated, inelastic aorta. =syphilitic aortitis= [illustration: fig. 7.--syphilitic aortitis of long standing. the aortic valves are curled and thickened, the heart is enlarged and the cavity of the left ventricle is dilated. (milwaukee county hospital.)] the seat of election of the syphilitic poison is in the aorta just above the aortic valves, fig. 7, and in the ascending portion of the arch. there are semitranslucent, hyaline-like plaques which have a tendency to form into groups and, instead of undergoing an atheromatous change as in the ordinary nodular form of arteriosclerosis, they are prone to scar formation with puckering, so that macroscopically the nature of the process may, as a rule, be readily diagnosed. microscopically the process is found to be a subacute inflammation of the media, which has been called a mesaortitis. there is marked small celled infiltration around some of the branches of the vasa vasorum and there appears to be actual absorption of the tissue elements of the middle coat. this is accompanied by hypertrophy of the intimal tissue. there follows degeneration in the deeper portions of this new tissue and new capillaries are formed which have their origin in the inflammatory area in the media. as is everywhere the case throughout the body, granulation tissue in the process of healing contracts and forms scars. this explains the scar formation in the aorta. when the process is more acute, instead of there being a reparative attempt on the part of the intima, there is actual stretching of the wall at the weakened spot and there results an aneurysmal dilatation. =spirochet㦠pallidã¦= have been found in the degenerated media and in small gummata which were situated beneath the intima. within the past years it has been found that a large percentage of patients with cardiovascular disease give the wassermann reaction. in cases of aortic insufficiency, the reaction is present in almost every case. this is in marked contrast to the cases of diffuse endocarditis where the reaction is rarely present. according to adami the effects of syphilis upon the aorta are the following: (1) the primary disturbance is a granulomatous, inflammatory degeneration of the media; (2) this leads to a local giving way of the aorta; (3) if this be moderate it results in a strain hypertrophy of the intima and of the adventitia, with the development of a nodose intimal sclerosis; (4) if it be extreme, there results, on the contrary, an overstrain atrophy of the intima and aneurysm formation; (5) the intimal nodosities are here not of an inflammatory type and are nonvascular, although, with the progressive laying down of layer upon layer of connective tissue on the more intimal aspect of the intima, the earlier and deeper-placed layers of new tissue gain less and less nourishment, and so are liable to exhibit fatty degeneration and necrosis; (6) these products of necrosis exert a chemotactic influence upon the nearby vessels of the medial granulation tissue, with, as a result, (a) a secondary and late entrance of new vessels into the early and deeply-placed atheromatous area, (b) absorption of the necrotic products, (c) replacement by granulation tissue, (d) contraction of the granulation tissue, and (e) depression and scarring of the sclerotic nodules so characteristic of syphilitic sclerosis. in the smaller arteries and arterioles the arteriosclerotic process appears on superficial examination to be a different process from that in the aorta and large arteries, but the difference is only apparent. it will be recalled that there is relatively much more muscle tissue in the arterioles than in the large arteries. the size, of course, is much less. large nodular plaques are not possible. the atheromatous degeneration is not marked. in the smaller muscular arteries is seen the intimal proliferation, the stretching of the moenckeberg type, and the calcification of the media rather than the intima. the media is thinned beneath the marked intimal proliferation so that the artery exhibits translucent areas when held to the light. again, there is seen degeneration of the muscle and replacement by connective tissue with or without hypertrophy of the intima. in the arterioles three kinds of changes occur: a muscular hypertrophy; a fibrosis of all the coats; or a marked proliferation of the intimal endothelium. the last two are probably the same process, the connective tissue having its origin in the proliferated endothelial cells. such a deposition of layer upon layer of cells in an arteriole and the resulting fibrosis leads to the condition of disappearance of the lumen of the vessel, endarteritis obliterans. this obliterating endarteritis is not, of course, due alone to syphilis. syphilis is only a type of poison which produces such changes as have been described above. it is in the organs such as the kidney, liver, spleen, and intestines that one sees the most perfect examples of this obliterating endarteritis. endarteritis deformans is a term applied to the condition of the arteries as a result of irregular thickenings and deposits of lime salts in the walls. these changes give rise to marked tortuosity of the vessels. occasionally such an obliterating process takes place in a larger artery. a thrombus forms and by a process of central softening, new channels permeate the thrombus, thus restoring to some extent the function of the vessel. that the same process leads at one time to thinning and at another time to thickening of the arterial walls has been noted above. prof. adami holds that the regular development of layer upon layer of new connective tissue is non-inflammatory. he calls it a "strain hypertrophy." it is analogous to the localized hypertrophy of bone where the muscle tendons are attached, as is so frequently seen in athletes. the increased tension on connective tissue, provided that it is not overstrained, leads to its overgrowth, but only when there is sufficient nourishment. such conditions are adequately fulfilled in the arteries. when a local giving way under pressure occurs in the media, the intima is put on the stretch (see fig. 8), and there results a hypertrophy of the intima until the volume of the new tissue and the resistance which this affords to the mean distending force, balances the loss sustained by the weakened media. when the balance is struck, the hypertrophy is arrested. the youngest tissue is thus found directly beneath the endothelium. now should this local weakening of the media have an acute origin, instead of a stimulus to growth there is overstrain, and there is, in consequence, not hypertrophy but atrophy. the beginning process is here a mesaortitis, but the acuteness of the poison, and the pressure from within the artery so stretches the artery that there is no compensatory hypertrophy, but a thinning, and the ground is prepared for aneurysmal dilatation or pouching. [illustration: fig. 8.--i, media weakened at m' with overgrowth of intima filling in the depression. ii, with postmortem rigor and contraction of the muscles of the media and removal of the blood pressure from within, the stretched media at m'' contracts; the intimal thickening thus projects into the arterial lumen. (after adami.)] again, one not infrequently encounters intimal nodosities when the underlying media appears of normal thickness. the explanation of this apparent exception is that the media in the living aorta is actually thinned, but the layers of subintimal tissue deposited over the weak spot due to strain hypertrophy become bulged inward when the pressure is relieved, as at postmortem. the media has not lost all of its elasticity (see fig. 9), hence it contracts and there is the appearance of a nodule on the intima beneath which is a media equal in thickness to that of the healthy surrounding media. [illustration: fig. 9.--schematic representation of the increased strain brought to bear upon the cells of the intima, int., when the media, med., undergoes a localized expansion through relative weakness. (after adami.)] the essential lesion in arteriosclerosis of the aorta and large arteries is a degeneration in the middle coat. this may be brought about by a variety of poisons circulating in the body. in syphilis, for example, the initial lesion has been shown to be a mesaortitis. the media seems to be dissolved, the artery is consequently thinned, there is actual depression along the level of the vessel. the elastic fibers disappear and small-celled infiltration takes its place. the intima hypertrophies, layer upon layer being added in an attempt to restore the strength of the vessel. there is also, as a rule, rather pronounced hypertrophy of the adventitia. =experimental arteriosclerosis= within the past few years many workers have attempted by various means, to produce arterial lesions in animals, chiefly rabbits and dogs. the present status is somewhat chaotic, some affirming and some denying that arterial changes follow the various methods employed. following the injection of small, repeated doses of adrenalin over a certain period of time, changes occur in the arteries of rabbits which are arteriosclerotic in type, the essential lesion being a degeneration of the muscular and elastic tissue of the media with the consequent production of aneurysm in the vessel. this is said by some to be quite like the type of arteriosclerosis in man which has been so well described by moenckeberg. the degenerations in the arteries following the experimental lesions are of the nature of a fatty metamorphosis, and later proceed to calcification. barium chloride, digitalin, physostigmin, nicotin and other substances, as well as adrenalin, have been found to exert a selective toxic action on the muscle cells of the middle coat of the aorta. the infundibular portion of the pituitary body, the portion which is developed from the infundibulum of the brain, possesses an internal secretion, which, injected intravenously, causes a marked rise of blood pressure and slowing of the heart beat. so far as i know, this active principle of the gland has not been used in an attempt to produce experimentally the lesions of arteriosclerosis. wacker and hueck succeeded in producing aortic disease in rabbits which they considered to be in many points quite like human arteriosclerosis. they injected the rabbits intravenously with cholesterin. they feel that this is of great importance in view of the fact that exercise (muscle metabolism) dyspnea, certain poisons, as well as adrenalin, and even adrenal extirpation occasion a high cholesterin content of the blood. anitschow's experiments are confirmatory. he fed rabbits on large amounts of cholesterin-containing substances (yolk of egg, brain tissue) and pure cholesterin and found changes in the intima and inner portion of the media consisting of fatty infiltration between the muscle and elastic fibres, advent of small round cells and large phagocytic cells containing fat droplets of cholesterin esters. the elastic fibres were dissolved, broken up into fibrill㦠and these seemed to be absorbed. the internal elastic lamina as such disappeared and the inner layer of the aorta fused with the middle coat. he considers these changes to be quite analogous to those found in human aortas. oswald loeb produced changes in the arteries of rabbits by feeding them sodium lactate (lactic acid). his controls fed on other acids became cachectic, but showed no arterial changes. he further found that in 100 gm. of human blood there was normally from 15 to 30 mg. of lactic acid. after heavy work, he found as much as 150 gm. he considers that after adrenalin or nicotin injections, the function of the liver is so disturbed that lactic acid is not bound. the arteriosclerosis is actually due to the presence of free lactic acid in the circulation. he succeeded, also, in producing lesions of the intima in a dog fed for a long time on protein poor diet, plus lactic acid and sodium lactate. another investigator, steinbiss, fed rabbits on animal proteins only, a diet totally foreign to their natural habits. he succeeded, however, in keeping some alive for three months. he also tried various substances and in the general conclusions says that no aortic changes could be produced in animals kept in natural living conditions by any mechanical means, increase of blood pressure, digital compression, hanging by hind legs, etc. in infectious diseases, especially septic, widespread sclerotic changes occurred in the aorta. a most suggestive conclusion in this "the most important result of feeding rabbits with animal proteins is, along with a constant glycosuria, disease of the aorta and peripheral arteries which is identical with changes in the aorta produced by injections of adrenalin. the degree of disease of the circulatory system increases with the duration of the experiment." by a small addition of vegetable to the protein diet, the lives of the animals were prolonged at will. with this modification of the experiment, the findings in the vessel walls were noticeably altered. the changes affected chiefly the intima, to less degree the media, and histologically were very much like human intimal disease. i have been unable to produce the slightest arterial lesions in rabbits by intravenous injections of lead. frothingham had no success feeding animals with lead. in a study of autopsy material from persons up to 40 years, who died of infectious disease, he found changes in the arteries of those who had succumbed to infection with the pus cocci or to very severe infectious disease. these changes were, however, localized, and were not like those of the general diffuse arteriosclerosis. adler has recently reported experiments on dogs, to which he fed or injected intravenously various substances supposed to induce arteriosclerotic changes. he was unable to find any arterial lesions comparable to human arteriosclerosis. the difficulty experienced by experimenters is not surprising when the character of the changes is considered. arteriosclerosis is not an acute process. in its very nature, it is of months' or years' standing, the specific changes are of slow growth, and more in the nature of degeneration. it would seem that a very careful study of the histories of those with arteriosclerosis and a final examination upon the actual tissue might eventually give us data for the etiology. the most frequent site of disease in these experimental lesions is the thoracic aorta, and it is there also that the most severe changes are seen. while the toxic action is felt in the vessels all over the body, the lesions are, as a rule, scattered and small. the thoracic aorta stands the brunt of the high pressure, and this combined with the poisonous action of the drug or drugs, results in the formation of a fusiform aneurysmal dilatation which stops at the diaphragmatic opening. the aortic opening in the diaphragm seems to act as a flood gate, allowing only a certain amount of blood to flow through, and thus the abdominal aorta is protected to a great extent from the deleterious effects of increased pressure. focal degenerative lesions are, however, found in the abdominal aorta. changes somewhat analogous to those found in the human aorta as the result of intimal proliferations, are produced in animals by the toxins of the typhoid bacillus and the streptococcus pyogenes. clinically, thayer and brush have found that the arteries of those who have recovered from an attack of typhoid fever are more palpable than the arteries of average individuals of equal age who have never had the disease. experimentally, the changes caused by the toxins above noted are proliferations of cells in the intima and subintimal tissues, and a breaking up of the internal elastic lamin㦠into several parallel layers which stretch themselves among the proliferating cells. the diphtheria toxin, on the contrary, produces a lesion more like that caused by adrenalin. all pathologists are not agreed as to whether the experimental lesions produced by blood pressure raising drugs are similar to the arteriosclerotic changes in the arteries of man. some of the work on rabbits has been discredited for the reason that arteriosclerosis appears spontaneously in about fifteen per cent of all laboratory rabbits. furthermore, comparatively young rabbits have been found with arteriosclerosis. o. loeb, however, denies this. he has examined in the course of eight years 483 healthy rabbits and never found arterial changes. the spontaneous lesions can not be distinguished histologically from those due to adrenalin. they differ macroscopically in that the lesion is usually limited to a few foci near the origin of the aorta. lesions produced by the drugs enumerated above represent one type of experimental arteriosclerosis. more interesting and important are the experiments which seem to show that high tension alone is capable of producing lesions in arteries which in all respects correspond to adami's strain hypertrophy and overstrain theory. it has been shown that when a portion of vein is placed under conditions of high arterial pressure, as in a transplantation of a portion of vein into a carotid artery, the vein undergoes marked connective tissue hypertrophy which includes all the coats. this is evidently strain hypertrophy. again, it has been demonstrated that by suspending a previously healthy rabbit by the hind legs for three minutes daily over a period of three to four months, there results hypertrophy of the heart with thinning and dilatation of the arch and the upper part of the thoracic aorta. no change was found in the abdominal aorta. the carotids, however, were larger than normal and they showed typical intimal sclerosis with connective tissue thickening. neither i nor others have been able to confirm this experiment, so it is very doubtful whether mechanical pressure alone can produce true arteriosclerosis. some evidence is adduced to bear on this point, however, in the fact that sclerosis of the pulmonary artery follows often upon mitral stenosis. yet we do not know but that factors other than pressure alone produce the arteriosclerotic change in such cases, so we are forced back on our conclusion expressed above; viz., that experiments on animals fail to sustain the purely mechanical origin of arteriosclerosis. the changes in the intima constitute the effort on the part of nature to repair a defect in the vessel wall which is to compensate for the weakened media and the widened lumen. this applies only to true arteriosclerosis, not to the condition produced experimentally by the toxin of the typhoid bacillus, for example. when an artery loses its elasticity and begins to have connective tissue deposited in its walls, the pressure of the blood stretches the vessel which is now no longer capable of retracting when the pulse wave has passed, and, in consequence, the artery is actually lengthened. this necessarily causes a tortuosity of the vessel which can be easily seen in such arteries as the temporals, brachials, radials, and other arteries near the surface of the skin. the exact mechanism of increase of blood pressure is not satisfactorily explained. the smaller arteries all over the body are supplied with vasoconstrictor and vasodilator nerve fibers from the sympathetic nervous system. normally when an organ is actively functionating the vessels are widely dilated and the flow of blood is rapid. among the many factors which influence blood pressure and blood supply must be reckoned the psychic. we know that normally there is a certain resistance offered to the propulsion of blood through the arteries by the contraction of the heart. this tonus is essential to the maintenance of an equalized circulation. the muscular arterioles throughout the body by their tonus serve to keep up the normal blood pressure and to distribute the blood evenly to the various organs. contraction of a large area of arterioles increases the blood pressure and, strangely enough, the arteries respond to increased arterial pressure, not by dilatation, but by contraction. it would appear that rise of blood pressure tends to throw increased work upon the musculature of the arterioles. this may be sufficient only to cause them to hypertrophy, but further strain may easily lead to exhaustion and to dilatation. "as a result strain hypertrophy of the intima shows itself with thickening, and it may also be of the adventitia, resulting in chronic periarteritis. and now with continued degeneration of the medial muscle in those muscular arteries, fibrosis of the media may also show itself. i would thus regard muscular hypertrophy of the arteries and fibrosis of the different coats as different stages in one and the same process. whether these peripheral changes are the more marked, or the central, depends upon the relative resisting power of the elastic and muscular arteries of the individual respectively." (adami.) [illustration: fig. 10.--cross-section of a small artery in the mesentery. note that the vessel appears capable of being much widened. the internal elastic lamina is thrown into folds somewhat resembling the convolutions of the brain. note also that the middle coat of the artery is composed almost entirely of muscle. the enormous number of such vessels in the mesentery and intestines explains the ability of the splanchnic area to accommodate the greater part of the blood in the body. universal constriction of these vessels would naturally render the intestines anemic. the vasomotor control of these vessels plays an important rã´le in the distribution of the blood. small arteries in the skin and in other organs, possibly the brain, have a similar function. (microphotograph, highly magnified.)] it is conceivable that in one section of the body the vessels may be markedly contracted, but if there is dilatation in some other part there will be no increased work on the part of the heart, and theoretically, there should be no rise of blood pressure. the vascular system, however, while likened to a system of rubber tubes, must be regarded as a very live system, every subsystem having the property of separate control. for blood tension to be raised all over the body, conditions must favor the generalized contraction of a large area of arterioles. some authors consider that the so-called viscosity of the blood also is a factor in the causation of increased tension. the usual cause for the high tension is probably the presence in the blood of some poisonous substance. it is held by some authors that the great splanchnic area is capable of holding all the blood in the body and in respect of its liability to arteriosclerosis, it is second only to the aorta and coronary arteries. the enormous area of the skin vessels could probably contain most of the blood. the tone of the vasoconstrictor center controls the distribution of blood throughout the body. the fact that the vessels in the splanchnic area are frequently attacked by sclerotic changes means, as a rule, increase of work for the heart.[1] the resistance offered to the passage of the blood must be great and signifies that, for blood to travel at the same rate that it did before the resistance set in, more power must be expended in its propulsion. in other words, the heart must gradually become accustomed to the changed conditions, and, as a result of increased work, the muscle hypertrophies. (see fig. 11.) [1] longcope and mcclintock, however, conclude that permanent constriction of the superior mesenteric artery and celiac axis, as well as gradual occlusion of one or both of these vessels, may be present in dogs for at least five months without giving rise to definite and constant elevation of blood pressure or to hypertrophy of the heart. further, they have been unable to find at autopsy on man a definite association between sclerosis of the abdominal aorta and great splanchnic vessels and cardiac hypertrophy. [illustration: fig. 11.--enormous hypertrophy of left ventricle probably due to prolonged increased peripheral resistance. note that the whole anterior surface of the heart is occupied by the left ventricle. the right ventricle does not appear to be much affected. x2/3.] in diffuse arteriosclerosis accompanied by chronic nephritis the heart is always hypertrophied. this is a result, not a cause of the condition. in the pure type, there is hypertrophy only of the left ventricle without dilatation of the chamber. the muscle fibers are increased in number and in size, and there are frequently areas of fibrous myocarditis due to necrosis caused by insufficient nutrition of parts of the muscle. in these cases the coronary arteries share in the generalized arteriosclerotic process. the openings of the arteries behind the semilunar valves may be very small. there is often thickening and puckering of the aortic valves and of the anterior leaflet of the mitral valve leading, at times, to actual insufficiency of the orifice. later, when the heart begins to weaken, there is dilatation of the chambers and loud murmurs result, caused by the inability of the nondistensible valves to close the dilated orifices. until the compensation is established, it is impossible to say whether or not true insufficiency is present. in senile arteriosclerosis there is the physiologic atrophy of the media to be reckoned with. this change has already been referred to. when such degeneration has taken place, the normal blood pressure may be sufficient to cause stretching of the already weakened media with or without hypertrophy of the intima. the arteries may be so lined with deposits of calcareous matter that they appear as pipe stems. more frequently there are rings of calcified material placed closely together or irregular beading, giving to the palpating finger the impression of feeling a string of very fine beads. the arteries are often tortuous, hard, and are absolutely nondistensible. at times no pulse wave can be felt. the larger arteries such as the brachials and femorals are most affected. the walls become thinned and show cracks, and areas apparently, but not actually denuded of intima. yellowish-white, irregular, raised plaques are scattered here and there. interspersed among these areas are irregularly shaped clean-cut ulcers having as a rule a smooth base, and frequently on the base is a thin plate of calcified matter. the color of these denuded areas is usually brownish red or reddish brown. white thrombi may be deposited on these areas. the danger of an embolus plugging one of the smaller arteries is great and probably happens more often than we think. the collateral circulation is able to supply the thrombosed area. should the thrombus be on the carotid arteries, hemiplegia may result from cerebral embolism. on microscopic examination of the arteries there is seen extreme degeneration of all the coats, the degeneration of the media leading almost to an obliteration of that coat. on seeing such arteries as these one wonders how the circulation could have been maintained and the organs nourished. senile atrophy of the internal organs naturally goes hand in hand with such arterial changes. there is, as a rule, no increase in arterial tension; on the contrary, the pressure is apt to be low. this is readily understood when the heart is seen. this organ is small, the muscle is much thinned, it is flabby and of a brownish tint, the so-called "brown atrophy." microscopically, there is seen to be much fragmentation of the fibers with a marked increase of the brown pigment granules which surround the cell nuclei. cases are seen, however, in which blood pressure increases as the patient grows older. the hearts in such cases are more or less hypertrophied and show extensive areas of fibroid myocarditis. from what has been said, it follows that hypertension alone may be the cause of arteriosclerosis; that certain poisons in the blood which attack the media and cause it to degenerate and weaken cause arteriosclerosis without increased blood pressure; that the normal blood pressure may be, for the artery which is physiologically weakened in an individual over fifty, really hypertension, and arteriosclerosis may result. our observations lead us to believe that the process is at bottom one and the same. the different types noted clinically depend upon the nature of the etiologic factors and the kind of arterial tissue with which the individual is endowed. this view at least brings some order out of previous chaos, and corresponds well with our present knowledge of the disease. there are many cases of arteriosclerosis which lead to definite interference with the closure of the valves of the heart, particularly the aortic and the mitral. it has been said that puckerings of the valves frequently occur (fig. 12). this arteriosclerotic endocarditis at times leads to very definite heart lesions, chiefly aortic or mitral insufficiency, or both with, at times, murmurs of a stenotic character at the base. there is rarely true aortic stenosis, however. the murmur is caused by the passage of the blood over the roughened valves and into the dilated aorta. aortic stenosis is one of the rarest of the valvular lesions affecting the valves of the left heart, and should be diagnosed only when all factors, including the typical pulse tracings, are taken into consideration. [illustration: fig. 12.--aortic incompetence with hypertrophy and dilatation of left ventricle, the result of arteriosclerosis affecting the aortic valves. note how the valves have been curled, thickened, and shortened, the edges of valves being a half inch below the upper points of attachment. the anterior coronary artery is shown, the lumen narrowed. (reduced one-half.)] the kidneys, as a rule, show extensive sclerosis. they are small, firm, and contracted and not always to be differentiated from the contracted kidneys of chronic inflammation. the lesions of the arteriosclerotic kidney are due to narrowing and eventual obstruction of the afferent vessels. the organs are usually bright red or grayish red in color. at times there is marked fatty degeneration of cortex and medulla, giving to them a yellowish streaking. the capsule is here and there adherent, the cortex is much thinned and irregular. the surface presents a roughly granular appearance. the glomeruli stand out as whitish dots and the sclerosed arteries are easily recognized, as their walls are much thickened. the process does not, as a rule, affect the whole kidney equally, but rather affects those portions corresponding to the interlobular arteries. the replacement of the normal kidney tissue by connective tissue and the resulting contraction of this latter tissue leads to the formation of scars. as the process is not regular, the scarring is deeper in some places than in others, with the result that localized rather sharply depressed areas appear on the surface. the pelvis is relatively large and is filled with fat. the renal artery is often markedly sclerosed and the whole process may be due to localized thickening of the artery, or as part of a general arteriosclerosis. the latter is the more frequent. microscopically, it is seen that the tubules are atrophied, the bowman's capsules are, as a rule, thickened, and the glomeruli are shrunken or have been replaced by fibrous tissue. in places they have fallen out of the section. there is marked proliferation of connective tissue in cortex and medulla. the arterioles are thickened, the sclerosis being either of the intima or media or of both. there is even occlusion of many arterioles. changes in other organs as the result of arteriosclerosis of their afferent vessels occur, but are not so characteristic as in the kidney. in the brain the result of gradual thickening of the arterioles is a diminished blood supply, softening of the portion supplied by the artery, and later a connective tissue deposit. the occurrence of thrombi is favored and, now and again, a thrombus plugs an artery which supplies an important and even vital part of the brain. the arteries of the brain are end arteries, hence there is no chance for collateral circulation. it is therefore evident how serious a result may follow the disturbance in or actual deprivation of blood supply to any of the brain centers or to the internal capsule. =arteriosclerosis of the pulmonary arteries= there have been a number of cases of sclerosis of the pulmonary arteries, either alone, or associated with general systemic arteriosclerosis. a primary and a secondary form are recognized, the former in conjunction with congenital malformations of the heart, the latter as the result of severe infection or of mitral stenosis. these two causes seem to be the most important in the production of the arterial changes. the cases thus far described have revealed widespread thickening of the pulmonary arteries. if one may judge by the description of the pathologic changes, the condition is quite similar to that produced in a vein by transplantation along the course of an artery. the diffuse form with connective tissue thickening of all coats has been generally described. there is also obliterating endarteritis of the smaller vessels. in the etiology of the condition severe infection seems to play a prominent rã´le. the constant presence of right ventricular hypertrophy is interesting, the heart dullness extends, as a rule, far to the right of the sternum. in some of the cases no demonstrable changes were observed in the bronchial arteries or in the pulmonary veins. sanders has described a case of primary pulmonary arteriosclerosis with hypertrophy of the right ventricle. recently warthin[2] has reported a case of syphilitic sclerosis of the pulmonary artery which places the lesion in exactly the same category as that of syphilis in the systemic arteries. there was also aneurysm of the left upper division present and, to settle the etiologic nature of the process, spirochete pallida were found in the wall of the aneurysm sac and in that of the pulmonary artery. the microscopic picture in the pulmonary artery could not be told from that in a syphilitic aorta. [2] warthin, a. s.: am. jour. syph., 1918, i, 693. =sclerosis of the veins= phlebosclerosis not infrequently occurs with arteriosclerosis. it is seen in those cases characterized by high blood pressure. such increased pressure in the veins is due, for example, to cirrhosis of the liver which affects the portal circulation, or to mitral stenosis which affects the pulmonary veins. the affected vessels are usually dilated. the intima shows compensatory thickening especially where the media is thinned. as a rule all the coats are involved in the connective tissue thickening. occasionally hyaline degeneration or calcification of the new-formed tissue is seen. "without existing arteriosclerosis the peripheral veins may be sclerotic usually in conditions of debility, but not infrequently in young persons." (osler.) in many cases of arteriosclerosis, the pathologic changes are not confined to the arteries, but are found in the veins as well as in the capillaries. such cases could be called angiosclerosis. chapter iii physiology of the circulation no attempt will be made to cover the entire subject of the physiology of the circulation. only in so far as it relates to arteriosclerosis and blood pressure and has a bearing on the probable explanation of blood pressure phenomena will it be discussed. "the heart and the blood vessels form a closed vascular system, containing a certain amount of blood. this blood is kept in endless circulation mainly by the force of the muscular contractions of the heart; but the bed through which it flows varies greatly in width at different parts of the circuit, and the resistance offered to the moving blood is very much greater in the capillaries than in the large vessels. it follows, from the irregularities in size of the channels through which it flows, that the blood stream is not uniform in character throughout the entire circuit--indeed, just the opposite is true. from point to point in the branching system of vessels the blood varies in regard to its velocity, its head of pressure, etc. these variations are connected in part with the fixed structure of the system and in part are dependent upon the changing properties of the living matter of which the system is composed." (w. h. howell.) if the vascular system were composed of a central pump, projecting at every stroke a given amount of liquid into a series of rigid tubes, the aggregate cross sections of which were equal to the cross section of the main pipe, then the velocity at the openings would be the same as at the source (making allowances for friction). the problem would then be a simple one. in the circulation of the blood no such simple condition obtains. the capillary beds is an enormous area through which the blood flows slowly. from the time the blood is thrown into the aorta the velocity begins to diminish until it reaches its minimum in the capillaries. in no two persons is the initial velocity at the heart the same, nor in the same person is it the same at all times of day. the size of the heart, the actual strength of the muscle, the amount of blood ejected at every beat, and the size and elasticity of the aorta are some of the factors which determine the velocity of blood at the aortic orifice. when to these factors are added the differences in arterial tissue, the activity or resting stage of the various organs, etc., the question becomes exceedingly complicated. in spite of these many disturbing elements, attempts more or less successful have been made to estimate the velocity of the blood in animals. thus, in the carotid of the horse the velocity was found to be 300 mm. per second (volkman) and 297 mm. (chauveau); in the carotid of the dog, 260 mm. (vierordt). in the jugular vein of the dog vierordt found the velocity to be 225 mm. per second. these figures do not represent the actual velocity of the blood in all horses or all dogs, but they do give us some general idea of the rate of flow of the blood. for man it has been calculated that the velocity in the aorta is about 320 mm. per second. the velocity is not uniform in the large arteries, where at every heart beat there is a sudden increase followed by a decrease as the heart goes into diastole. the farther away from the heart the measurements are made the more even is the flow. observations by w. h. luedde with the zeiss binocular corneal microscope on the rate of flow in the conjunctival capillaries must modify somewhat our former conceptions. he finds that "the rate varies in the different arteries, capillaries, and veins from a barely perceptible motion to a little more than 1 mm. per second. further, some parts of the capillary network are ordinarily supplied with blood elements only occasionally. this is shown by the passage of a column of corpuscles along a certain line, followed after an interval of seconds, during which no corpuscles pass, by another column in the same line as before." the vessels of the conjunctiva probably are quite like superficial vessels in the skin and mucous membranes. therefore, we must be free to admit that the circulation in them is not absolutely steady. luedde found further that in syphilitics there were tortuosities, irregularities, minute aneurysmal dilatations and even obliterations of capillaries. some of the changes occurred as early as one month after infection. the rate in the capillaries of man is estimated to be between 0.5 mm. and 0.9 mm. per second. as the blood is collected into the veins and the bed becomes smaller, the velocity increases until at the heart it is almost the same as in the aorta. that the velocity could not be exactly the same is evident from the fact that the cross section of the veins, which return the blood to the right auricle, is greater than is the cross section of the aorta. the volume of the bed is subject to rapid and wide fluctuations, which are dependent on many causes, both physiologic and pathologic. the call of an actively functionating organ or group of organs causes a widening of a more or less extensive area, and the velocity necessarily varies. in states of great relaxation of the vessels there may be a capillary pulse. in order to force blood at the same rate through dilated vessels as through normal vessels, there must be more blood or there must be a more rapid contraction of the central pump. what actually happens, as a rule, is an increase in the rate of the heart beat. there are conditions--such, for example, as aortic insufficiency--where actually more blood is thrown into the circulation at every beat, so that the rate is not changed. it has been calculated that the average amount of blood thrown into the aorta at every systole of the heart is from 50 to 100 c.c. this is forcibly ejected into a vessel already filled (apparently) with blood. in order to accommodate this sudden accession of fluid, the aorta must expand. the aortic valves close, and during diastole the blood is forced through the vascular system by the forcible, steady contraction of the highly elastic aorta. other large vessels which branch from the aorta also have a part in this steady propulsion of blood. from seventy to eighty times a minute the aorta is normally forcibly expanded to accommodate the charge of the ventricle. it is not difficult to understand the great frequency of patches of sclerosis in the arch when these facts are borne in mind. what relationship the viscosity of the blood has to the rate and volume of flow is not fully understood. as yet there is not much known about the subject, and no one has devised a satisfactory means of measuring the viscosity. it is thought by some that an increased viscosity assists in producing an increased amount of work for the heart. =blood pressure= blood pressure is the expression used for a series of phenomena resulting from the action of the heart. as every heart beat is actual work done by the heart in overcoming resistance to the outflow of blood, this force is approximately measurable in a large artery such as the brachial. it has been determined that the pressure in the brachial artery is almost equal to the intraventricular pressure in the left ventricle. in animals it is easy to attach manometers to the carotid artery and to measure the blood pressure accurately. formerly the method consisted in attaching a tube and allowing the blood to rise in the tube. the height to which the blood rose measured the maximum pressure. this is a crude method and has been replaced by the u-tube of mercury with connection made to the artery by saline or ringer's solution. this apparatus is familiar to all physiologists. in man the measurement is most conveniently made from the brachial artery. there is some difference in the pressure in the femoral and the brachial and some use both arteries. however, the difficulty of adjusting instruments to the upper leg, the great force which must be used to compress the femoral artery and the relative inaccessibility of the leg as compared to the arm, make the leg an inconvenient part for use in blood pressure determinations. it is not to be recommended. blood pressure is a valuable aid in diagnosis and of material help in many cases in prognosis, but it is not infallible neither can it be used alone to diagnose a case. blood pressure is only one of many links in a chain of evidence leading to diagnosis. it has been badly used and much abused. it has been condemned unjustly when it did not furnish _all_ the evidence. it has been made a fetish and worshipped by both doctors and patients. a sane conception of blood pressure must be widely disseminated lest we find it being discarded altogether. blood pressure consists of more than the estimation of the systolic pressure. the blood pressure picture consists of (1) the systolic pressure, (2) the diastolic pressure, (3) the pulse pressure which is the difference between the systolic and diastolic pressure, (4) the pulse rate. expressed in the literature it should read thus: 120-80-40; 72. that tells the whole story in a brief, accurate form. this is recommended in history reporting. it must be ever kept in mind that a blood pressure reading represents the work of the heart at the _moment when it was taken_. within a few minutes the pressure may vary up or down. there is no normal pressure as such, but an average pressure for any group of people of the same age living under similar conditions. the habit of speaking of any systolic figure as normal should be broken. a pressure picture may be normal but a systolic reading, whatever it may be, is not accurately designated as normal. this distinction is worth insisting upon. =blood pressure instruments= there are several instruments which are in common use for the purpose of recording blood pressure in man. historically, the determination of blood pressure for man began with the attempt of k. vierordt in 1855 to measure the blood pressure by placing weights on the radial pulse until this was obliterated. the first useful instrument, however, was devised by marcy in 1876. he placed the hand in a closed vessel containing water connected by tubing with a bottle for raising the pressure and by another tube with a tambour and lever for recording the size of the pulse waves. he maintained that when pressure on the hand was made, the point where oscillations of the lever ceased was the maximal pressure, the point where the oscillations of the recording lever was largest, was the minimal pressure. this pioneer work was practically forgotten for twenty-five years. it was not until 1887 that v. basch devised an instrument which was used to some extent. this instrument recorded only maximum pressure. it consisted of a small rubber bulb filled with water communicating with a mercury manometer. the bulb was pressed on the radial artery until the pulse below it was obliterated and the pressure then read off on the column of mercury. v. basch later substituted a spring manometer for the mercury column. potain modified the apparatus by using air in the bulb with an aneroid barometer for recording the pressure. these instruments are necessarily grossly inaccurate. moreover, they do not record the diastolic pressure. in 1896 and 1897 further attempts were made to record blood pressure by the introduction of a flat rubber bag encased in some nonyielding material, which was placed around the upper arm. riva-rocci used silk, while hill and barnard used leather. the latter used a bulb or davidson syringe to force air into the cuff around the arm and palpated the radial artery at the wrist, noting the point of return of the pulse after compression of the upper arm, and reading the pressure on a column of mercury in a tube. except that the width of the cuff has been increased from 5 cm. to 12 cm., this is the general principle upon which all the blood pressure instruments now in use are based. most of the apparatuses make use of a column of mercury in a u-tube to record the millimeters of pressure. as the mercury is depressed in one arm to the same extent as it is raised in the other arm the scale where readings are made is .5 cm. and the divisions represent 2 mm. of mercury but are actually 1 mm. apart. the cuff was made 12 cm. in diameter because it was shown (v. recklinghausen) that with narrow cuffs much pressure was dissipated in squeezing the tissues. janeway has shown that with the use of the 12 cm. cuff accurate values are obtained independently of the amount of muscle and fat around the brachial artery. in other words if an actual systolic blood pressure of 140 mm. is present in two individuals, the one with a thin arm, the other with a thick arm, the instrument will record these pressures the same where a 12 cm. arm band is used. we need have no fear of obtaining too high a reading when we are taking pressure in a stout or very muscular individual. janeway also was the first to call attention to the fact that the diastolic or minimal pressure was at the point where the greatest oscillation of the mercury took place. this is difficult to estimate in many cases as the eye can not follow slight changes in the oscillation when the pressure in the cuff is gradually reduced. practically this is the case in small pulses. the riva-rocci instrument was modified by cook. (see fig. 13.) he used a glass bulb containing mercury into which a glass tube projected. the bulb was connected by outlet and tubing to the cuff and syringe. the glass tube was marked off in centimeters and millimeters and for convenience was jointed half way in its length. the instrument could be carried in a box of convenient size. this instrument is fragile and more cumbersome, although lighter in weight, than others and is very little used at present. [illustration: fig. 13.--cook's modification of riva-rocci's blood pressure instrument.] stanton's instrument (fig. 14) is practically cook's made more rigid in every way but without the jointed tube. the cuff has a leather casing, the pressure bulb is of heavy rubber, the glass tube in which the mercury rises is fixed against a piece of flat metal and there are stopcocks in a metal chamber introduced between the bulb and mercury with which to regulate the inand out-flow of air. the pressure can be gradually lowered conveniently without removing the pressure bulb. [illustration: fig. 14.--stanton's sphygmomanometer.] the most accurate mercury manometer is that of erlanger. (fig. 15.) the instrument is bulky and is not practicable for the physician in practice. the principle is that used by riva-rocci. there is an extra t-tube introduced between the manometer and air bulb connecting with a rubber bulb in a glass chamber. the oscillations of this are communicated to a marey tambour and recorded on smoked paper revolving on a drum. there is a complicated valve which enables the operator to reduce the pressure with varying degrees of slowness. the mercury is placed in a u-tube with a scale alongside it. the instrument is expensive and not as easy to manipulate as its advocates would have us believe. hirschfelder has added to the usefulness (as well as to the complexity) of the erlanger instrument, by placing two recording tambours for the simultaneous registering of the carotid and venous pulses. in spite of its complexity and necessary bulkiness, very valuable data are obtained concerning the auricular contractions. [illustration: fig. 15.--the erlanger sphygmomanometer with the hirschfelder attachments by means of which simultaneous tracings can be obtained from the brachial, carotid, and venous pulses.] one of the best of the mercury instruments is the brown sphygmomanometer. in this (fig. 16) the mercury is in a closed, all-glass tube so that it can not spill under any sort of manipulation. it is in this sense "fool-proof." the cuff, however, is poorly constructed. it is too short and there are strings to tie it around the arm. i have found that this causes undue pressure in a narrow circle and renders the reading inaccurate. in the clinic we use this mercury instrument with a long cuff like that provided by the tycos instrument. [illustration: fig. 16.--desk model baumanometer.] the faught instrument (fig. 17) is larger than the brown, but is less easily broken and is not too cumbersome to carry around. the substitution of a metal air pump for the rubber makes the apparatus more durable. [illustration: fig. 17.--the faught blood pressure instrument. an excellent instrument which is quite easily carried about and is not easily broken.] the v. recklinghausen instrument is not employed to any extent in this country. it is both expensive and cumbersome, and has no advantages over the other instruments. several other instruments have been devised and new ones are constantly being added to the already large list. with those employing mercury the principle is the same. the aim is to make an instrument which is easily carried, durable, and accurate. in all the mercury instruments the diameter of the tube is 2 mm. one would suppose that there would be noticeable differences in the readings of the different mercury instruments depending upon the amount of mercury used in the tube. by actual weight there is from 35 to 45 gms. of mercury in the several instruments. after many trials, no noticeable differences in blood pressure readings can be made out between a column weighing 35 gm. and one weighing 45 gm. there is, however, the inertia of the mercury to be overcome, friction between the tube and the mercury, and vapor tension. the mercury is therefore not as sensitive to rapid changes of pressure in the cuff as a lighter fluid would be. the mercury must be clean and the tube dry so that there is no more friction than what is inherent between the mercury and glass. in making readings on a rapid pulse the oscillations of the mercury column are apt to be irregular or to cease now and then, due to the fact that the downward oscillation coincides with a pulse wave, or an upward oscillation receives the impact of two pulse waves transmitted through the cuff. instruments have been devised to obviate this difficulty, but they have not come into favor. they are usually too complicated and at present can not be recommended. [illustration: fig. 18.--rogers' "tycos" dial sphygmomanometer.] an instrument devised by dr. rogers (the "tycos") has met with considerable popularity. (fig. 18.) this is not an instrument which operates with a spring and lever. the instrument is composed essentially of two metal discs carefully ground and attached at their circumferences to the metal casing below the dial. there is an air chamber between these discs through the center of which air is forced by the syringe bulb. when air is forced into the space between these two discs, they are forced apart to a very slight extent, with the highest pressures only 2-3 mm. of bulging occurs. from data gathered after extensive use for five years these discs were not found to have sprung. a lever attached to a cog which in turn is attached to the dial needle magnifies to an enormous extent the slightest expansion of the discs. every dial is handmade and every division is actually determined by using a u. s. government mercury manometer of standard type. no two dials therefore are alike in the spacing of the divisions of the scale but every one is calibrated as an individual instrument. there is no doubt in the author's mind that for the general practitioner the instrument has some advantages over the mercury instruments. it reveals the slightest irregularity in force of the heart beat. the oscillation of the dial needle is more accurately followed by the eye than is that of the column of mercury. the needle passes directly over the divisions of the scale, while with usual mercury instruments the scale is an appreciable distance (sometimes .5 cm.) from the column of mercury at the side. (fig. 19.) the diastolic pressure is more easily read on the "tycos." it is where the maximum oscillation of the needle occurs as the pressure is slowly released from the cuff. although it does not appear that this instrument, if properly made and standardized, could become inaccurate, nevertheless it is advisable to check it every few months against a known accurate mercury manometer instrument. [illustration: fig. 19.--detail of the dial in the "tycos" instrument.] [illustration: fig. 20.--faught dial instrument.] [illustration: fig. 21.--detail of the dial of the faught instrument.] another perfectly satisfactory dial instrument is the faught (figs. 20 and 21). the general plan of this differs in some minor points from the "tycos." i have compared the two and have found no difference in the readings. both can be recommended. [illustration: fig. 22.--the sanborn instrument.] one or two other cheaper dial instruments are on the market. the sanborn seems to be quite satisfactory. (fig. 22.) it is cheaper than the other dial instruments. there is this much to be said, no instrument using a spring as resistance to measure pressure can be recommended. =technic= the same technic applies to all the mercury instruments. the patient sits or lies down comfortably. the right or left arm is bared to the shoulder, the cuff is then slipped over the hand to the upper arm. (see fig. 23.) at least an inch of bare arm should show between the lower end of the cuff and the bend of the elbow. the rubber is adjusted so that the actual pressure from the bag is against the inner side of the arm. the straps are tightened, care being taken not to compress the veins. the upper part of the cuff should fit more snugly than the lower part. the part of the instrument carrying the mercury column is now placed on a level surface; the two arms of the mercury in the tube must be even, and at _0_ on the scale. with the fingers of one hand on the radial pulse, the bag is compressed until the pulse is no longer felt. (see fig. 24.) one should raise the pressure from 10-12 mm. above this, and close the stopcock between the bulb and the mercury tube. in a good instrument the column should not fall. if it does there is a leak of air in the system of tubing and arm bag. now with the finger on the pulse, or where the pulse was last felt, gradually allow air to escape by turning the stopcock so that the column of mercury falls about 2 mm. (one division on the scale) for every heart beat or two. one must not allow the column of mercury to descend too slowly as it is uncomfortable for the patient and introduces a psychic element of annoyance which affects the blood pressure. on the other hand, the pressure must not be released too rapidly, else one runs over the points of systolic and diastolic pressure and the readings are grossly inaccurate. it is impossible to say how rapidly the mercury must fall. every operator must find that out for himself by practice. the first perceptible pulse wave felt beneath the palpating finger at the wrist, represents on the scale the systolic pressure. this can be seen to correspond to a sudden increase in the magnitude of the oscillation of the mercury column. the systolic pressure, thus obtained, is from 5-10 mm. lower than the real systolic pressure. the more sensitive the palpating finger, the more nearly does the systolic pressure reading approach that found by using such an instrument as erlanger's, where the first pulse wave is magnified by the lever of the tambour. [illustration: fig. 23.--method of taking blood pressure with a patient in sitting position.] [illustration: fig. 24.--method of taking blood pressure with patient lying down.] the pressure is now allowed to fall, until the palpating finger feels the largest possible pulse wave, which is coincident with the greatest oscillation of the mercury. this is the diastolic pressure. beyond this point there is no oscillation of the mercury column. the difference between the two is the pulse pressure. thus the pulse is felt after compression at 120 on the scale, and the maximum oscillation occurs at 80. the systolic pressure is 120 mm., the diastolic is 80 mm., and the pulse pressure is 40 mm. with the "tycos" or faught the arm band is snugly wound around the arm, the bag next to the skin and the end tucked in, so that the whole band will not loosen when air is forced into the bag. the cuff is blown up until the pulse is no longer felt. one should raise the pressure not more than 10 mm. above the point of obliteration of the pulse. the valve is then carefully opened so that the needle gradually turns toward zero. at the first return of the pulse wave felt at the wrist, the needle is sure to give a sudden jump. this is the systolic pressure and is read off on the scale. the needle is now carefully watched until it shows the maximum oscillation. this is the diastolic pressure. the difference between the two is, as above, the pulse pressure. in taking pressure one should take the average of several, three or four. moreover, one must not take consecutive readings too quickly and one must be sure that between every two readings all the air is out of the cuff and that the mercury or dial is at zero. _it has been repeatedly shown that in a cyanosed arm the systolic pressure is raised so that even slight cyanosis between readings must be carefully avoided._ the only accurate method of determining both the systolic and diastolic pressure, but especially the diastolic, is by the so-called auscultatory method. (see fig. 25.) the cuff is adjusted in the usual way and one places the bell of a binaural stethoscope over the brachial artery from one to two centimeters below the lower edge of the cuff.[3] care must be taken that the bell is not pressed too firmly against the arm and that the edge of the bell nearest the cuff is not pressed more firmly than the opposite end. for this purpose, one can not use the ordinary bowles stethoscope or any of the other much lauded stethoscopes, because the surface of the bell is too large. the diameter of the bell must not be more than twenty-five millimeters, twenty is still better. it is advisable before beginning the observation to locate with the finger the pulse in the brachial artery just above the elbow, so that the stethoscope may be placed over the course of the artery. (fig. 26.) the first wave which comes through is heard as a click, and occurs at a point on the manometer or dial scale from 5-10 mm. higher than can usually be palpated at the radial artery. this is the true systolic pressure. by keeping the bell of the stethoscope over the brachial artery while the pressure is falling, one comes to a point when all sound suddenly ceases. this is said to be the diastolic pressure. this is incorrect as will be shown later. [3] a firm makes a stethoscope so that the bell is clamped on the arm leaving both the operator's hands free. [illustration: fig. 25.--observation by the auscultatory method and a mercury instrument. one hand regulates the stop cock which releases air gradually.] [illustration: fig. 26.--observation by the auscultatory method and a dial instrument. the right hand holds the bulb and regulates the air valve.] =arterial pressure= the arterial pressure in the large arteries undergoes extensive fluctuations with every heart beat. the maximum pressure produced by the systole of the left ventricle of the heart is known as the =maximum= or =systolic pressure=. it practically equals the intraventricular pressure. the minimum pressure in the artery, the pressure at the end of diastole, is called the =diastolic pressure=. the difference between the systolic and diastolic pressures is known as the =pulse pressure=. there is yet another term known as the =mean pressure=. for convenience, this may be said to be the arithmetical mean of the systolic and diastolic pressures. actually, however, this can not be the case, owing to the form of the pulse wave, which is not a uniform rise and fall--the upstroke being a straight line, but the downstroke being broken usually by two notches. we do not make use of the mean pressure in recording results. it is of experimental interest and needs only to be mentioned here. [illustration: fig. 27.--schema to illustrate the gradual decrease in pressure from the heart to the vena cava: (a), arteries; (c), capillaries; (v), veins; (a), aorta, pressure 150 mm.; (b), brachial artery, pressure 130 mm.; (f), femoral vein, 20 mm.; (ivc), inferior vena cava, 3 mm. (modified from howell.)] it has been shown that the mean pressure is quite constant throughout the whole arterial system. the maximum pressure necessarily falls as the periphery of the vascular system is approached. in general it may be said that the minimal pressure is quite constant. too little attention is paid to minimal and pulse pressure. the minimal pressure is important, for it gives us valuable data as to the actual propulsive force driving the blood forward to the periphery at the end of diastole. it is readily understood how the maximum pressure falls as the periphery is approached, until in the arterioles the maximum and minimum pressures are about equal. the pressure then in these arterioles is practically the same as the diastolic pressure. actually it is a few millimeters less. the diastolic blood pressure would, therefore, measure the peripheral resistance and, as the maximum for systolic pressure represents approximately the intraventricular pressure, the difference between the two, the pulse pressure, actually represents the force which is driving the blood onward from the heart to the periphery. it is hence very evident that the mere estimation of the systolic pressure gives us but a portion of the information we are seeking. the pulse pressure is subject to wide fluctuations but as a rule for any one normal heart it remains fairly constant as the rate varies. in a rapidly beating heart the diastole is short and the diastolic pressure rises. if the systolic pressure does not also rise, as in a normal heart following exercise, we will say, the pulse pressure falls. we know that when the pulse rate is constant, vasodilatation causes a fall in diastolic pressure and a rise in pulse pressure. on the contrary, vasoconstriction causes a rise in diastolic pressure and a fall in pulse pressure. it is very probably the case that with two individuals of equal age and equal pulse rate, and equal systolic pressure of 160 mm., the one with a diastolic pressure of 110 mm. and, therefore, a pulse pressure of 50 mm. is much worse off than the other with a diastolic pressure of 90 mm. and a pulse pressure of 70 mm. the latter may be normal for the age of the person especially when certain forms of fibrous arteriosclerosis accompanied by enlarged heart are present. the former is not normal for any age. low pulse pressure usually means a weak vasomotor control and is only found in failing circulation or in markedly run down states, such as after serious illness or in tuberculosis. therefore, it is most important to estimate accurately the diastolic pressure as well as the systolic pressure, for only in this way can we obtain any data of value regarding the driving power of the heart and the condition of the vasomotor system. a high systolic pressure does not necessarily mean that a great deal of blood is forced into the capillaries. actually it may mean that very little blood enters the periphery. the heart wastes its strength in dilating constricted vessels without actually carrying on the circulation adequately. =normal pressure variations= the systolic pressure varies considerably under conditions which are by no means abnormal. thus, the average for men at all ages is about 127 mm. hg. (all measurements are taken from the brachial artery, with the individuals in the sitting posture.) for women the average is somewhat lower, 120 mm. hg. the pressure is lowest in children. in children from 6-12 years the average systolic pressure is 112 mm. normally, there is a gradual increase as age comes on, due, as will be shown in the succeeding chapter, to physiologic changes which take place in the arteries from birth to old age. in the chart here appended is graphically shown the normal variations in the blood pressure at different ages compiled from observations made on one thousand presumably normal persons. (fig. 28.) [illustration: fig. 28.--chart showing the normal limits of variation in systolic blood pressure. (after woley.)] the diastolic pressure has been estimated to be about 35 to 45 mm. hg lower than the systolic pressure, and consequently these figures represent the pulse pressure in the brachial artery of man. this is equivalent to saying that every systole of the left ventricle distends this artery by a sudden increase in pressure equal to the weight of a column of mercury 2 mm. in diameter and 35 to 45 mm. high. naturally, at the heart the pressure is highest. as the blood goes toward the capillary area the pressure gradually decreases until, at the openings of the great veins into the heart, the pressure is least. at the aorta (a) the pressure (systolic) is approximately 150 mm. hg, at the brachial artery (b) it is 130 mm., in the capillary system (c) it is 30 mm., in the femoral vein (f) it is 20 mm., at the opening of the inferior vena cava (i) it is 3 mm. attention has been called to the normal systolic pressure at different ages. this is not the only cause for variations in the blood pressure. normally, it is greater when in the erect position than when seated, and greater when seated than when lying down. during the day there are well-recognized changes. the pressure is lowest during the early morning hours, when the person is asleep. in women there are variations due to menstruation. muscular exercise raises the blood pressure markedly. the effect of a full meal is to raise the blood pressure. the explanation is that during and following a meal there is dilatation of the abdominal vessels. this takes blood from other parts of the body, provided that the other factors in the circulation remain constant. a fall of pressure would necessarily occur in the aorta. to compensate for this, there is increased work on the part of the heart, which reveals itself as increased pressure and pulse pressure. it is well known that the interest in the process taken by an individual upon whom the blood pressure is estimated for the first time tends to increase the rate of the heart and to raise the blood pressure. for this reason the first few readings on the instrument must be discarded, and not until the patient looks upon the procedure calmly can the true blood pressure be obtained. as a corollary to this statement, mental excitement, of whatever kind, has a marked influence on the pressure. the patient must remain absolutely quiet. raising the head or the free arm causes the pressure to rise. another important physiologic variation is produced by concentrated mental activity. this tends to hurry the heart and increase the force of the beat. in short, it may be stated as a general rule that any active functioning of a part of the body which naturally requires a great excess of blood tends to elevate the blood pressure. at rest the pressure is constant. variations caused by the factors mentioned act only transitorily, and the pressure shortly returns to normal. =the auscultatory blood pressure phenomenon= since the first description of the auscultatory blood pressure sounds by korotkov in 1905, this method has been more and more employed until today it is the standard, recognized method of determining the points in the blood pressure reading. when one applies the 12 cm. arm band over the brachial artery and listens with the bell of the stethoscope about one cm. below the cuff directly over the brachial artery near the bend of the elbow, one hears an interesting series of sounds when the air in the cuff is gradually reduced. the cuff is blown up above the maximum pressure. as the air pressure around the arm gradually is lowered, the series of sounds begins with a rather low-pitched, clear, clicking sound. this is the first phase. this only lasts through a few millimeters fall when a murmur is added and the tone becomes louder. this click and murmur phase is the second phase. a few millimeters more of drop in pressure and a clear, sharp, loud tone is audible. usually this tone lasts through a greater drop than any of the other tones. this is the third phase. rather suddenly the loud, clear tone gives place to a dull muffled tone. in general the transition is quite sharp and distinct. this is the fourth phase. the tone gradually or quickly ceases until no tone is heard. this is the fifth phase (ettinger.) the first phase is due to the sudden expansion of the collapsed portion of the artery below the cuff and to the rapidity of the blood flow. this causes the first sharp clicking sound which measures the systolic pressure. the second, or murmur and sound phase, is due to the whorls in the blood stream as the pressure is further released and the part of the artery below the cuff begins to fill with blood. the third tone phase is due to the greater expansion of the artery and to the lowered velocity in the artery. a loud tone may be produced by a stiff artery and a slow stream or by an elastic artery and a rapid stream. this tone is clear cut and in general is louder than the first phase. the fourth phase is a transition from the third and becomes duller in sound as the artery approaches the normal size. the fifth phase, no sound phase, occurs when the pressure in the cuff exerts no compression on the artery and the vessel is full throughout its length. it is generally conceded that the sounds heard are produced in the artery itself and not at the heart. the tones vary greatly in different hearts. a very strong third tone phase or prolongation of this phase usually means that the heart which produces the tone is a strongly acting one, although allowances must be made for a sclerosed artery in which there is a tendency to the production of a sharp third phase. weakness of the third phase, as a rule, indicates weakness of the heart and this dulling of the third phase may be so excessive that no sound is produced. goodman and howell have carried this method further by measuring the individual phases and calculating the percentage of each phase to the pulse pressure. thus, if in a normal individual the systolic pressure is 130 mm., the diastolic 85 mm., and the pulse pressure 45 mm., the first phase lasts from 130 to 116 or 14 mm., the second from 116 to 96, or 20 mm., the third from 96 to 91 or 5 mm., the fourth from 91 to 85, or 6 mm. the first phase would then be 31.1 per cent of the total pulse pressure, the second phase 44.4 per cent, the third phase 11.1 per cent, and the fourth phase 13.3 per cent. they consider that the second and third phases represent cardiac strength (c. s.) and the first and fourth represent cardiac weakness (c. w.). they believe that c. s. should normally be greater than c. w. in the example above c. s.:c. w. = 55.5:44.4. in weak hearts, especially in uncompensated hearts, the conditions are reversed and c. w. > c. s. this is often the case. as a heart improves c. s. again tends to become greater than c. w. they think that the phases should be studied in respect to the sounds and also to the encroachment of one sound upon another. these observations are interesting but we have not found the division into phases as helpful as it was thought to be. we spent a great deal of time on this question. all that can be said, in my opinion, is that a loud, long third phase is usually evidence of cardiac strength. a further interesting feature which can be heard in all irregular hearts is a great difference in intensity of the individual sounds. goodman and howell call this phenomenon tonal arrhythmia. irregularities can be made out by the auscultatory method which can not be heard at the heart. in anemia the sounds are very loud and clear and do not seem to represent the actual strength of the heart. the general lack of vasomotor tone in the blood vessels together with some atrophy and flabbiness of the coats probably explains the loud sounds. in polycythemia the sounds have a curious, dull, sticky character and can not be differentiated accurately into phases, a condition which was predicted from the knowledge of the sharp sounds in anemia. in not all cases can all phases be made out. it is usually the fourth phase which fails to be heard. in such cases the loud third tone almost immediately passes to the fifth phase or no sound phase. the importance of this will later be taken up. "in arteriosclerosis, with hardening and loss of elasticity of the vessel walls, the auscultatory phenomena, according to krylow, are apt to be more pronounced, since the back pressure at the cuff probably causes some dilatation of the vessel above it, while the lumen of the vessel is smaller than normal. both of these factors cause an increased rapidity in the transmission of the blood wave when pressure in the cuff is released, which in time favors the vibration of the vessel walls. "in high grade thickening of the arterial walls, however, especially where calcification had occurred, fischer found that the sounds were distinctly less loud than normal, the more so in the arm, which showed the greater degree of hardening. according to ettinger's experience, the rapidity of the flow distinctly increases the auscultatory phenomenon." (gittings.) the sounds depend upon the resonating character of the cuff, upon the size and accessibility of the vessel, upon the force of the heart beat, and upon the velocity of the blood. =the maximum and minimum pressures= the maximum (systolic) pressure is read at the point where the first audible click is heard after the cuff is blown up and the pressure gradually reduced by means of the needle valve in the hand bulb or on the upright of the glass containing the mercury. all are agreed upon this point. there has been some dispute as to the place where the diastolic pressure should be read. korotkov considered that the diastolic pressure should be read at the fourth phase when the loud tone suddenly becomes dulled. others held that the diastolic pressure should be read at the fifth phase, the absence of all sound. experiments carried out to determine this point were made by me with the assistance of prof. eyster and dr. meek at the physiological laboratory of the university of wisconsin. we arranged apparatus making it possible to hold the pressure in the carotid artery of dogs at maximum or minimum. a femoral artery was then dissected and an instrument devised to compress the artery with a water jacket. the whole was connected up with a kymograph. a time marker was put in so as to record the place where changes in sound were heard while listening below the cuff around the femoral artery. two sets of records were taken. one with pressure greater than minimum pressure and a falling pressure over the femoral artery (fig. 29), the other with pressure at zero and gradually raised to minimum pressure (fig. 30). both sets of records showed the same result; viz., that at a point corresponding to the sudden change of tone the pressure on the artery corresponded to the minimum pressure. it was therefore concluded that experimentally in dogs the point where diastolic pressure should be read is at the tone change from clear to dull, not at the point where all sound disappears. [illustration: fig. 29.--tracing of auscultatory phenomena. (see explanation in legend of fig. 30.)] [illustration: fig. 30.--figures are to be read from left to right. the top line records the points where sounds were heard, the figures above the short vertical lines refer to tones (see text). mx. b. p., maximum blood-pressure. m. b. p., minimum blood-pressure. p. b., pressure bulb recorder. it was impossible to lower and raise this bulb by hand without obtaining the great irregular oscillations of the attached lever above the mercury manometer. b. l., base line.] erlanger showed some years ago, that with his instrument, the point at which diastolic pressure should be read was at the instant when the maximum oscillation of the lever suddenly became smaller. while checking up the graphic with the auscultatory method using erlanger's instrument, it was noticed that the disappearance of all sound did not correspond with the sudden diminution of the oscillation of the lever connected with the brachial artery. a series of records were carefully made on patients. it was seen that during the period of the third tone phase the oscillations of the lever on the drum reached a maximum (fig. 31) and remained at approximately the same height for some millimeters while the pressure was gradually falling. at a point at which the third tone, clear and distinct, became dull, there was an appreciable decrease in the height of the pulse wave. from this point to the disappearance of all sound there was a gradual diminution of the size of the pulse waves. [illustration: fig. 31.--fast drum. sudden decrease in size of pulse wave at 4, marking the change from clear sharp tone to dull tone.] [illustration: fig. 32.--slow drum. sudden decrease in amplitude at 4.] for normal pressures the difference between the fourth (dull) tone and the fifth (disappearance of all tone) phase, amounted to 4 to 10 mm. occasionally the difference was so little, the change from sharp third tone through fourth dull tone to disappearance of all sound was so abrupt, that one could take the disappearance of all sound as the diastolic pressure, with an error of not more than 2 to 4 mm. this is within the limits of normal error and practically may be used by those who have difficulty in noting the change from third to fourth phase. for high pressures, however, the difference between fourth and fifth phases was never less than 8 mm., and was found as much as 16 mm. the diastolic, therefore, should always be taken at the fourth phase if possible. it was found that with the dial instrument the greatest fling of the lever corresponded to the third phase and the sudden lessened amplitude of the oscillation was at the fourth phase and was coincident with the change of tone from sharp to dull. thus the diastolic pressure may be read off on the dial scale by watching the fling of the hand and with some practice one might acquire considerable accuracy. it is better, simpler, and, for most observers, more accurate to use the stethoscope and hear the change of sound. =the relative importance of the systolic and diastolic pressures= the systolic pressure represents the maximum force of the heart. it is measured by noting the first sound audible over the brachial artery using the auscultatory method. it is the summation of two factors largely; the force expended in opening the aortic valves (potential) and the force expended from that point to the end of systole, the force which is actually driving the blood to the periphery (kinetic). to start the blood in motion, the heart must overcome a dead weight equal to the sum of all the forces holding the aortic valves closed. this sum of factors, called the peripheral resistance, must be reached and passed by the force of the ventricular beat before one drop of blood is set in motion along the aorta. this factor of resistance assumes a great importance. the systolic pressure is always fluctuating as it depends upon so many conditions, and the calls of the body except during sleep are many and various. in a study of diurnal variations in arterial blood pressure it has been found that--(1) a rise of maximum pressure averaging 8 mm. of hg. occurs immediately on the ingestion of food. a gradual fall then takes place until the beginning of the next meal. there is also a slight general rise of the maximum pressure during the day. (2) the range of maximum pressure varies considerably in different individuals, but the highest and lowest maximum pressures are practically equidistant from the average pressure of any one individual.[4] [4] weyse, a. w., and lutz, b. r.: diurnal variations in arterial blood pressure, am. jour. physiol., 1915, xxxvii, 330. the pressure is lowest during sleep and gradually rises near the end of sleep, so that on awakening the pressure was the same as before sleep. physiologically there are many conditions which modify the systolic pressure. sleep, position, meals, exercise, emotional states cause often wide fluctuations which may be very sudden. it should be constantly borne in mind, that the systolic pressure reading which is made, is the maximum effort of the heart at that moment only. the diastolic pressure measures the peripheral resistance. it measures the work of the heart, the potential energy, up to the moment of the opening of the aortic valves. it is the actual pressure in the aorta. the diastolic pressure is not very variable; it is not subject to the same influences which disturb the systolic pressure. it fluctuates as a rule, within a small range. it is not affected by diet, by mental excitement, by subconscious psychic influences, to anything like the extent to which the systolic pressure is affected by the action of these factors. the diastolic pressure is determined by the tone in the arterioles and is under the control of the vasomotor sympathetic system. any agent which causes chronic irritation of the whole vasomotor system produces increase in the peripheral resistance with consequent rise in the diastolic pressure. any agent which acts to produce thickening of the walls of the arterioles, narrowing their lumina, produces the same effect. such states naturally result in increased work on the part of the heart, which as a result, hypertrophies in the left ventricle. the increase in size and strength is a compensatory process in order to keep the tissues supplied with their requisite quota of blood. conversely, paralysis of the vasomotor system produces fall of diastolic pressure which, if long continued, results in death. the diastolic pressure then is of importance for the following reasons: 1. it measures peripheral resistance. 2. it is the measure of the tonus of the vasomotor system. 3. it is one of the points to determine pulse pressure. 4. pulse pressure measures the actual driving force, the kinetic energy of the heart. 5. it enables us to judge of the volume output, for pulse pressure which is only determined by measuring both systolic and diastolic pressure, is such an index. 6. it is more stable than the systolic pressure, subject to fewer more or less unknown influences. 7. it is increased by exercise. 8. it is increased by conditions which increase peripheral resistance. 9. the gradual increase of diastolic pressure means harder work for the heart to supply the parts of the body with blood. 10. increased diastolic pressure is always accompanied by increased pulse pressure, and increased size of the left ventricle, temporarily (exercise) or permanently. 11. decreased diastolic pressure goes hand in hand with vasomotor relaxation, as in fevers, etc. 12. low diastolic pressure is frequently pathognomonic of aortic insufficiency. 13. when the systolic and diastolic pressures approach, heart failure is imminent either when pressure picture is high or low. when all these factors are taken into consideration, it becomes apparent that the diastolic pressure is most important, if not the most important part of the pressure picture. up to within a very brief time all the statistical evidence of blood pressure was based on systolic readings alone. this data is most valuable and much has been learned as to diagnosis and prognosis, but it is a mass of data based on a one-sided picture and can not be as valuable as the statistics which will undoubtedly be published later when all the pressure picture figures can be analyzed. =pulse pressure= the pulse pressure is the actual head of pressure which is forcing the blood to the periphery. at every systole a certain amount of blood 75-90 c.c. (howell) is thrown violently into an already comfortably filled aorta. the sudden ejection of this blood instigates a wave which rapidly passes down the arteries as the pulse wave. the elastic recoil of the aorta and large arteries near the heart contract upon the blood and keep it moving during diastole. normally the blood-vessels are highly elastic tubes with an almost perfect coefficient of elasticity. the pulse pressure varies under normal conditions from 30 to 50 mm. hg. there is a very definite relationship between the velocity of blood and the pulse pressure which is expressed thus; velocity = pulse rate x pulse pressure.[5] further it has been demonstrated that under normal conditions and during various procedures--the pulse pressure is a reliable index of the systolic output.[6] [5] erlanger and hooker: an experimental study of blood pressure and of pulse pressure in man, johns hopkins hosp. rep., 1904, xii, 145. [6] dawson and gorham: the pulse pressure as an index of systolic output, jour. exper. med., 1908, x, 484. increased pulse pressure therefore goes hand in hand with greater systolic output. physiologically this is most ideally seen during exercise. following exercise the pulse rate increases, the systolic pressure rises greatly, the diastolic slightly or not at all. the pulse pressure therefore is increased. the velocity also is much increased. the call comes for more blood and the heart responds. in the chronic high pulse pressures there are four correlated conditions which, so far as i have studied them, are always present. these are: (1) an increase in size of the cavity of the left ventricle. the ventricle actually by measurement contains more blood than normal, and therefore throws out more blood at every systole. the volume output is greater per unit of time. (2) there is actual permanent increase in diameter of the arch of the aorta. this is a compensating process to accommodate the increased charge from the left ventricle. (3) there are on careful auscultation over the manubrium, particularly the lower half, breath sounds which vary from bronchial to intensely tubular, depending upon the anatomic placing of the aorta, the shape of the chest, and the degree of dilatation. often there is very slight impairment of the percussion note as well. (4) there is increase in size of all the large distributing arteries, carotids, brachials, femorals, renals, celiac axis, etc., with fibrous changes in the media, loss of some elasticity, and increase in size of the pulse wave. increased pulse pressure means increased volume output, but does not always mean increased velocity. the proper distribution of blood to the various organs of the body is regulated by the vasomotor system acting upon the small arteries which contain considerable unstriated muscle. when fibrous arteriosclerosis is present there is loss of elasticity in the distributing arteries and a greater volume of blood must be thrown out by the ventricle at every systole in order that every organ shall have its full quota of blood. a force which is sufficient to send blood through elastic normal distributing tubes becomes totally insufficient to send the same amount of blood through tortuous and more or less inelastic tubes. it is evident then that pulse pressure is exceedingly important. it can only be determined by measuring both the _systolic_ and _diastolic_ pressure. the pulse rate must also be known in order to compute the velocity. it is essential to have the whole pressure picture for all cases if correct conclusions are to be drawn. in an irregular heart, especially in the cases due to myocardial disease, it is quite impossible to determine the true diastolic pressure. one can only approximate it and say that the pulse pressure is low or high. as a matter of fact the real systolic pressure can not be determined. for this figure the place on the scale where most of the beats are heard may be taken for the average systolic pressure. no one can seriously maintain that he can measure the diastolic pressure under all circumstances. by means of the auscultatory method of measuring blood pressure we are able to determine irregularities of force in the heart beats more easily than by listening to the heart sounds. a pulsus alternans is readily made out. the irregular tones heard over the brachial artery in cases of irregular heart action have been called "tonal arrhythmias." =blood pressure variations= a recent study of diurnal variations in blood pressure has shown that while the maximum pressure rises after the ingestion of food and steadily rises slightly throughout the day, the minimum blood pressure is very uniform throughout the day, and is little affected by the ingestion and digestion of meals. when it is affected, a rise or a fall may take place. throughout the day, it tends to become slightly lower. the pulse pressure then is greater towards evening. weysse and lutz in a study of this question draw the following conclusions: 1. a rise of maximum pressure averaging 8 mm. of hg occurs immediately on the ingestion of food. a gradual fall then takes place until the beginning of the next meal. there is also a slight general rise of the maximum pressure during the day. 2. the average maximum blood pressure for healthy young men in the neighborhood of 20 years of age is 120 mm. of hg. this pressure obtains commonly one hour after meals. the higher maximum pressures occur immediately after meals, and the lower, as a rule, immediately before meals. 3. the range of maximum pressure varies considerably in different individuals, but the highest and lowest maximum pressures are practically equidistant from the average pressure of any one individual. 4. the minimum blood pressure is very uniform throughout the day, and is little affected by the ingestion and digestion of meals. when it is affected a rise or fall may take place. there is a tendency for a slight general lowering of the minimum pressure throughout the day. 5. the average minimum blood pressure for healthy young men in the neighborhood of 20 years of age is 85 mm. of hg. thus we get an average pulse pressure of 35 mm. of hg. 6. pulse pressure, pulse rate, and the relative velocity of the blood flow are increased immediately upon the ingestion of meals. they attain the maximum, as a rule, in half an hour, and then decline slowly until the next meal. there is a general increase in each throughout the day. these measurements were made upon persons at rest. almost any form of exercise would have made the variations much greater. no account is taken of the psychic variations which for the physician are the most important to bear in mind. neglect to take this variation into account will inevitably lead to false conclusions. the average diurnal blood pressure record of the ten subjects

hot and cold applications on and within the abdomen, hammett, tice and larson found that heat applied to the outside of the abdomen raises the blood pressure. the application of cold produces no change. either hot or cold saline introduced within the abdomen causes a fall in blood pressure. experimentally, certain drugs such as adrenalin, barium chloride, nicotine, digitalis, strophanthus and the infundibular portion of the pituitary body known as pituitrin raise the maximum pressure. in the clinic it is difficult to conclude always whether the drug alone is responsible for rise in maximum pressure. adrenalin given intravenously will raise the pressure. so will digitalis and strophanthus. i have watched the maximum pressure rise within three minutes following an intravenous injection of gr. 1/100 (0.0006 gm.) strophanthin 20 mm. of hg: i have seen the subcutaneous injection of 10 minims of adrenalin repeated several times daily for six months fail to have the least effect on the blood pressure picture. elevation of the foot of the bed about nine inches proved so efficacious in steadying failing hearts in acute infectious diseases, particularly typhoid, that a study was made of the effect upon blood pressure. many observations were made, but no instrumental proof of rise in blood pressure could be adduced. exercise always raises blood pressure, the maximum much more than the minimum. in athletes the minimum pressure may actually fall, the maximum rise so that a greater volume output results from the greater pulse pressure. shock and hemorrhage lower it. hemorrhage lowers also the pulse pressure, and it may be possible to prognosticate internal hemorrhage by frequent estimations of the systolic and diastolic pressures (wiggers). compression of the superior mesenteric artery or the celiac axis in dogs raises the blood pressure measured in the carotid artery for a period of at least an hour. this seems to be dependent on purely mechanical causes, and is not a reflex vasomotor phenomenon. (longcope and mcclintock.) experimentally blood pressure can be increased by direct compression of the brain as cushing has shown. it was thought at one time that in man the same effect would result from tumor of the brain or especially from subdural or extradural hemorrhage following head injuries. this, however, is not the case. no information of great value can be obtained by the measurement of blood pressure in these states. we do know that too high and too prolonged compression of the medulla brings about exhaustion of the cardiac center accompanied with rapid pulse, low pressure and eventual death. =hypertension= all the conflict during the past few years over the subject of blood pressure has revolved around this much overworked word. hypertension means high pressure, and yet it carries with it a suggestion of high pressure which is harmful to the individual. as a matter of fact hypertension is a compensatory process, it is often a saving process in spite of the fact that it carries possibilities of harm in its possessor. it has been made a fetish, a god to fall down before and worship and it has been the means of holding a torch of fear over a patient which has not been lost on the charlatans. popularization of blood pressure has brought its crop of evils, no one of which has been as fruitful in dollars to unprincipled quacks as hypertension. hypertension is the expression on the part of the circulation to meet new conditions in the tissues so that all tissues will be nourished and all will be enabled to function. looked at from that point of view it is a conservative process and in many cases it is. it is not an average normal state, but it is normal state for the man who has it in chronic form. hypertension should be viewed rationally and its proper place in the whole make-up of the patient determined. hypertension is a relative term. what might be high pressure in a man of sedentary habits who reaches the age of fifty, might not be high pressure in a full blooded formerly athletic man of the same age. temporary hypertension due to excitement, exercise, etc., must be kept in mind. it is not intended to convey the impression that hypertension is of no moment. it is a matter for investigation, but not a matter to worship as the all-in-all. hypertension is, after all, a physiologic response on the part of the organism in order to maintain the circulation in equilibrium in the face of conditions which tend to produce vasoconstriction in large areas and, therefore tend to deprive these areas of blood. that there must be some substance in the blood stream which causes this constriction seems certain. what it is, is not at present known. recently, voegtlin and macht[7] have isolated a crystalline substance from the blood of man and other mammals which they regard as a lipoid and closely related to cholesterin. this substance was recovered by them from the cortex of the adrenal gland. this becomes of added interest in the light of observations made by gubar (quoted by voegtlin and macht). he noted "that the vasoconstricting properties of blood serum vary in different pathologic conditions, being increased in nephritis, for instance, and diminished in others." in some experiments made in the summer of 1913, we found there was no marked difference in the anaphylactic shock produced in half-grown rabbits by the injection of normal and uremic blood serum. as lipoids do not cause anaphylaxis, there should be no difference in the reaction of normal and uremic sera unless in one there was some form of protein not in the other. this does not seem to be the case. the presence of something in the circulation, therefore, produces constriction of vessels. this calls for more force in contraction on the part of the heart. this substance may be of lipoid nature. the continued presence of this hypothetical substance naturally would lead to hypertrophy of the heart. [7] isolation of a new vasoconstrictor substance from the blood and the adrenal cortex, jour. am. med. assn., 1913, lxi, 2136. what makes hypertension of significance is not the hypertension itself, but the fact that it is the expression of processes going on in the body which demand exhaustive investigation. to attach a blood pressure cuff to the arm, find the pressure, and diagnose hypertension is like putting a thermometer under the tongue, noting a rise in the mercury, and diagnosing fever. what causes the hypertension? can the causes be removed? those are the really vital questions after the symptom hypertension has been discovered. all states of hypertension are accompanied by more or less increase of pulse pressure. in other words the systolic pressure is always increased to greater degree than the diastolic pressure. in studies carried out in the wards and pathological laboratory of the milwaukee county hospital, milwaukee, we found that in all of the cases of chronic high blood pressure with resulting high pulse pressure four correlated factors were found. if any one of these factors is present, the other three are found. 1. in all high pulse pressure cases there is increase in the size of the cavity of the left ventricle. the ventricle actually contains more blood when it is full, and throws out, therefore, more blood at each systole. the actual volume output is greater per unit of time. such hearts always show increase in thickness of the ventricular wall. i quite agree with stone,[8] who says, "it is merely to be emphasized that when the pulse pressure persistently equals the diastolic pressure (high pressure pulse, in other words) with a resulting 50 per cent, _overload_, which means the expenditure of double the normal amount of kinetic energy on the part of the heart muscle, cardiac hypertrophy has occurred." they are found in aortic insufficiency, in chronic nephritis, in the diffuse fibrous type of arteriosclerosis, and in some cases of exophthalmic goiter. such a condition occurs temporarily after exercise. [8] stone, w. j.: the differentiation of cerebral and cardiac types of hyperarterial tension in vascular diseases, arch. int. med., november, 1915, p. 775. 2. in all high pulse pressure cases there is actual permanent increase in diameter of the arch of the aorta. this is a compensating process to accommodate the increased charge from the left ventricle. smith and kilgore[9] have shown this to be true in cases of chronic nephritis with hypertension. their research confirms my own observations. they found dilatation of the arch in (1) syphilis (that is, aortitis); (2) age over 50 (that is, probable factor of arteriosclerosis); (3) other serious cardiac enlargement, and (4) hypertension (with more or less hypertrophy, as in chronic nephritis). [9] smith, w. h., and kilgore, a. r.: dilatation of the arch of the aorta in chronic nephritis with hypertension, am. jour. med. sc., 1915, cxlix, 503. in ten cases showing arches at the upper limit of normal (that is, 6 cm. in diameter) and hypertrophy of the heart, three were chronic mitral endocarditis; one was chronic aortic endocarditis; three were chronic mitral and aortic endocarditis, and there was one each of hyperthyroidism, pericarditis and adherent pericardium. in fourteen cases of hypertension (highest systolic 270 mm., average systolic, 215 mm.), all showed cardiac hypertrophy. "all but three of these cases had great vessels whose transverse diameters measured over the normal limit of 6 cm., and in one of those measuring 6 cm. the roentgen-ray diagnosis was 'slight dilatation' of the arch." smith and kilgore are at a loss to explain the three exceptions. they did not give diastolic pressures, so pulse pressures are not known. possibly the three exceptions were cases of high diastolic pressure in which the pulse pressure possible was not over 60 mm. such cases might show "slight dilatation of the arch," but not marked dilatation, such as was found in the other, evidently high pulse pressure cases. we have found that only the high pulse pressure cases show dilatation of the arch. certain high tension cases which have had a very high diastolic pressure do not reveal any accurately measurable dilatation of the aortic arch. an empty aorta after death is quite different from a functionating aorta during life. hence the dilatation which is found postmortem must have been considerable during life. and conversely, a dilatation which was present during life might not be looked on as such after death. 3. in all high pulse pressure cases one will find on careful auscultation over the manubrium, particularly its lower half, breath sounds which vary from bronchial to intensely tubular. at times the percussion note will be slightly impaired, as mccrae[10] has shown in dilatation of the arch of the aorta. this auscultatory sign is evidence of some more or less solid body in the anterior mediastinum which is lying on the trachea and permits the normal tubular breathing in the trachea to be audible over the upper part of the sternum. it is found in cases of dilated aortic arch. fluoroscopic examination has confirmed the findings on auscultation. [10] mccrae, thomas: dilatation of the arch of the aorta, am. jour. med. sc., 1910, cxl, 469. 4. in all high pulse pressure cases, in which the pulse pressure is over 70 mm. of mercury, there is increase in the size of all large distributing arteries, carotids, brachials, femorals, renals, celiac axis, etc., with fibrous changes in the media, loss of some of the elasticity, and in the palpable superficial arteries, increase in size of the pulse wave. increased pulse pressure means increased volume output, but does not always mean increased velocity. the proper distribution of blood to the various organs of the body is regulated by the vasomotor system acting on the small arteries which contain considerable unstriated muscle. in order that there may be enough blood at all times and under varying conditions of rest and function, there must be a proper supply coming through the distributing vessels, the large arteries, those containing much elastic tissue, and only a very small amount of unstriated muscle tissue or none whatever. fibrous sclerosis of these vessels causes them to become enlarged and tortuous and to lose much of their elasticity, which is essential for the even distribution of blood. a greater blood volume is therefore necessary in order that the organs may receive their quota of blood. a force which is sufficient to send blood through elastic normal distributing tubes becomes totally insufficient to send the same amount of blood through tortuous and more or less inelastic tubes. as a compensatory process the pulse pressure increases. for this to increase, the left ventricular cavity dilates, the arch dilates, and as a greater force must be exerted to keep the increased mass in motion, the heart responds by hypertrophy of its left ventricle and becomes itself the subject of fibrous changes in the myocardium. the mass movement of blood is therefore greater in high pulse pressure cases than in cases of normal pulse pressure. in cases of chronic interstitial nephritis--contracted granular kidney--it may well be that the sclerosis of the arteries is a secondary process caused, as adami thinks, by the hypertension itself. in aortic insufficiency the situation is somewhat different. the high pulse pressure is due to a very low diastolic pressure, for in my experience with uncomplicated aortic insufficiency the systolic pressure is, as a rule, not much increased above the normal for the individual's age. here peripheral resistance is so low that a capillary pulse is common. the volume output per unit of time is greatly increased, the arch of the aorta is dilated, and the pulse is large. the fact that a large part of the blood regurgitates during diastole back into the ventricle, and the fact that the diastolic pressure is low means that there is no increased resistance to overcome, and the systolic pressure is not raised. stone[11] has divided the cases of hypertension into the cerebral and cardiac types. he finds that there is a difference in prognosis and in the mode of death in the two groups. he has further attempted to judge of the work placed upon the heart by calculating what he calls the heart load or pressure-ratio. for example, he takes a normal pressure at 120-80-40. the relation between 80 and 40 is 1/2 or 50 per cent. that he considers normal. when the heart load increases so that the pulse pressure equals or exceeds the diastolic pressure, the heart load is 100 per cent or more, he considers the danger of myocardial exhaustion graver than when the heart load is normal or less than 50 per cent. [11] stone, w. j.: arch. int. med., 1915, xvl, 775. it is his opinion, in which i heartily concur, "that an individual with a systolic pressure of 200 and a diastolic pressure of 140, is in greater danger of cerebral death than an individual with a systolic pressure of 200 and a diastolic pressure of 100." he is "likewise certain that the individual with a systolic pressure of 200 and a diastolic of 90 to 100 is in greater danger of a cardiac death. it is apparently the constant high diastolic pressure rather than the intermittently high systolic pressure which predisposes to cerebral accident." i have not been able to confirm all of stone's conclusions. his contention holds good for some cases, but not, in my experience, for the great majority of the hypertension cases. i feel that in the classification of the chronic high pressure case we can go one step farther and split his first group into two usually differentiable groups. syphilis is not an etiological factor in any of these groups. it is not considered that these groups are absolutely distinct and can always be rigidly separated. there are variations and combinations which render an exact separation impossible. but bearing this in mind the following classification is proposed as a working classification. group a. chronic nephritis. group b. essential hypertension. group c. arteriosclerotic hypertension. group a. _chronic nephritis._ these are the cases with a high-pressure picture, that is to say, high systolic (200+) and high diastolic (120-140+). the pulse pressure is much increased. the palpable arteries are hard and fibrous. there is puffiness of the under eyelids, which is more pronounced in the morning on arising. polyuria with low specific gravity and nycturia are present. there are almost constant traces of albumin in the urine, with hyaline and finely granular casts. functionally these kidneys are much under normal. the functional capacity determined by mosenthal's modification of the schlayer-hedinger method shows a marked inability to concentrate salts and nitrogen. the phthalein output is below normal. as the case advances the phthalein output becomes less and less, until a period is reached when there are only traces or complete suppression at the end of a two-hour period. such patients may live for ten weeks (one of our cases) or longer, all the time showing mild uremic symptoms, and suddenly pass into coma and die. the natural end of patients in this group is either uremia or cardiac decompensation (so-called cardiorenal disease). cerebral accidents may happen to a small number. it is only to this group, in my opinion, that the term cardiorenal disease should be applied. formerly i believed that all high systolic pressure cases were cases of chronic nephritis of some definite degree. from the purely pathologic standpoint that is true, but from the important, functional standpoint it is far from being the true state of the cases. in this group there is marked hypertrophy and moderate dilatation of the left ventricle with dilatation and nodular sclerosis of the aorta. the kidneys are firm, red, small, coarsely granular, the cortex much reduced, the capsule adherent. cysts are common. it is the familiar primary contracted kidney. mallory calls this capsular-glomerulonephritis. the etiology is obscure. often no cause can be found. again, there is a history of some kidney involvement following one of the acute infectious diseases, or it may follow the nephritis of pregnancy. usually, however, these cases fall into the group of secondary contracted kidneys, chronic parenchymatous nephritis. illustrative case.--r. z., a woman, aged thirty-six years, was seen july 26, 1916, in coma. there was a history of typhoid fever at nineteen years, but no other disease. she had had nine full-term pregnancies, the last one thirteen months previously. for a week before the onset of the present illness she had complained of severe headaches and dizziness. there were no heart symptoms. for the past year she has had nycturia. physical examination revealed tubular breathing beneath the manubrium, a few rales in the chest, an enlarged heart (left side), with a systolic murmur over the aortic area. blood pressure was 178-125-53, the pulse rate 96, leucocytes 27,250. venesection of 500 c.c. of blood and intravenous injections of 500 c.c. of 5 per cent nahco_3 in normal saline were employed. lumbar puncture withdrew 60 c.c. of clear fluid under pressure with 6 cells per cubic millimeter. the eye grounds showed distinct haziness of the disks and dilatation of the veins. blood pressure after venesection was 164-122-42, pulse 76, but in a few days rose to 222-142-80, pulse 70. a second venesection of 400 c.c. and proctoclysis of 1000 c.c. saline solution was tried. the blood-pressure now was 198-140-58. the ph of the blood was 7.6, the alkaline reserve was 35 volume per cent (van slyke), and the co_2 tension of the alveolar air (marriott) was 25 mm. the phthalein on the day following the second venesection was 45 per cent in two hours. the urine at first showed 500 c.c. in twenty-four hours, specific gravity 1016, albumin and casts. later she passed 1300 to 1600 c.c. with specific gravity around 1010. the blood-pressure fluctuated considerably, reaching as low as 138-98-40, pulse 88. she was discharged improved september 10, 1916. she had constant headache but managed to keep up. in june, 1917, she suddenly died in an uremic coma. group b. this one might designate as the hereditary type, although there is not always a history in the antecedent. this group includes the robust, florid, exuberantly healthy people. they often are heard to boast that they have never had a doctor in their lives. they are usually thick-set or very large, fleshy people. the pressure picture is exceedingly high. the pulse pressure is moderately increased. the arteries are rather large, fibrous, and often quite tortuous, although this is not always the case. some persons have hard, small, fibrous arteries. there is no puffiness beneath the eyes, no polyuria, and no nycturia as a rule. the urine is of normal amount, color, and specific gravity. albumin is only rarely found and then in traces, but careful search of a centrifuged specimen invariably reveals a few hyaline casts. the phthalein excretion is normal or only slightly reduced. the kidneys excrete salt and nitrogen normally. it is in this group that apoplexy is found most frequently. the rupture of the vessel occurs when the victim is in perfect health, often without any warning. occasionally when such a case recovers sufficiently to be around, cardiac decompensation sets in later and he dies then of the cardiac complications. pathologically the hearts of such persons are found to have the most enormous hypertrophy of the wall of the left ventricle. the cavity is somewhat enlarged, as is always the case when the pulse-pressure is increased, but the size of the cavity is not the striking feature. the aorta is fibrous, thick walled, and the arch is slightly dilated. there are patches of arteriosclerosis. one such case seen only at autopsy had a rupture of the aorta just above the sinus of valsalva and died of hemopericardium. the kidneys are of normal size, dark red, firm, the capsule strips readily, the surface is smooth or finely granular, the cortex is not decreased. the pyramids are congested and red streaks extend into the cortex. microscopically the capsules of the glomeruli are a trifle thickened; a few show hyaline changes. there is rather diffuse, mild, round-cell infiltration between the tubules. the tubular epithelium shows little or no demonstrable changes. the arterioles are generally the seat of a moderate thickening of the intima and media, but it is not usual to find obliterating endarteritis. there is evidently a diffuse fibrous change which has not affected either the tubules or glomeruli to any great extent. illustrative case.--l. c., a man, aged fifty-six years, stonemason by trade, is a stocky, thick-necked individual. he had never been ill in his life until a year ago, when he fell from his chair unconscious. he had a right-sided hemiplegia which has cleared up so completely that except for a very slight drag to his foot he walks perfectly well. he came in complaining of shortness of breath and cough. there was no swelling of the feet. here evidently was left-heart decompensation. examination showed the blood pressure to be 240-130-110, pulse irregular, 104 to the minute. there were cyanosis and rales throughout both chests. the urine was normal in color, specific gravity 1025, small amount of albumin, few casts, hyaline and granular. the phthalein elimination was 65 per cent in two hours. under rest, purgatives, and digitalis he was much improved. he has since had two other apoplectic strokes, the last of which was fatal. when these patients are seen with acute cardiac decompensation, there are, of course, much albumin and many casts in the urine, and the phthalein output is, for the time being, decreased. group c. this might be called the arteriosclerotic high-tension group (stone's cardiac group). the cases are usually over fifty years old. they are men and women who have lived high and thought hard. often they have had periods of great mental strain. many men in this group were athletes in their young manhood. many have been fairly heavy drinkers, although never drinking to excess. they are usually well nourished and inclined to stoutness. the pressure picture is high systolic with normal or only slightly increased diastolic and large pulse pressure. the arteries are large, full, fibrous, usually tortuous. the heart is very large, the apex far down and out. there is no polyuria; nycturia is uncommon, quite the exception. the urine is normal in color, amount, and specific gravity. albumin is only rarely found and hyaline casts are not invariably present. the phthalein excretion is quite normal and the excretions of salt and nitrogen are also normal. the terminal condition in most of the patients in this group is cardiac decompensation. they may have several attacks from which they recover, but after every attack the succeeding one is produced by less exertion than the preceding one, and it becomes more and more difficult to control attacks. eventually the patients become bedor chair-ridden, and finally die of acute dilatation of the heart. occasionally patients in this group may have a cerebral attack, but in my experience this is uncommon. pathologically the heart is large, at times true _cor bovinum_, dilated and hypertrophied. the cavity of the left ventricle is much dilated. the aorta is dilated and sclerosed. the kidneys are increased in size, are firm, dark red in color, with fatty streaks in the cortex. the capsule strips readily and the cortex is normal in thickness or only slightly increased. the organ offers some resistance to the knife. the microscope shows small areas scattered throughout where the glomeruli are hyalinized, the stroma full of small round cells, the tubules dilated, and the cells are almost bare of protoplasm. naturally the tubules are full of granular cast material. also the arterioles show extensive intimal thickening, fibrous in character, with occasional obliterating endarteritis. one gets the impression that the small sclerotic lesions are the result of anemia and gradual replacement of scattered glomeruli by fibrous tissue. for the most part the kidney, except for the chronic passive congestion, appears quite normal. one can readily understand that in such a kidney function could not have been much interfered with. illustrative case.--c. k., an active, stout, business man, aged fifty-six years, consulted me on account of shortness of breath and swelling of the feet in may, 1915. he had just returned from a hospital in another city, where he had gone with what was apparently cardiac decompensation. in his early manhood he had been a gymnast and a prize winner. he has worked hard, often given way to violent paroxysms of temper, has eaten heavily but drunk very moderately. the heart was greatly enlarged, the arch of the aorta dilated, a mitral murmur was audible at the apex. the radials and temporals were large, tortuous, and fibrous. the blood pressure picture ranged around 180-90-90. he was easily made dyspneic and had a tendency to swelling of the lower legs. the urine was acid, of normal specific gravity, normal in amount, normal phthalein, normal concentration of salt and nitrogen, contained albumin only when he was suffering from decompensation of the heart. casts were always found. he finally died, after sixteen months, with all the symptoms of chronic myocardial insufficiency. the heart was enormous, a true _cor bovinum_. the kidneys were typical of this condition, possibly somewhat larger than usual. =hypotension= when the pressure is constantly below the normal, it is called hypotension. this may be transient--as in fainting--it may be a normal state of the individual, it occurs in most fevers and in a great variety of diseases, including anemias. in arteriosclerosis, especially the diffuse (senile) type, the blood pressure is invariably low, and may be spoken of as hypotension. the heart in such a case is small, the muscle is flabby, there is brown atrophy of the fibers, and some replacement of the muscle cells by connective tissue. the same causes which have produced general arteriosclerosis have also produced sclerosis of the coronary arteries, and probably the lessened blood supply accounts for much of the atrophy of the heart muscle. in typhoid fever the maximum blood pressure during beginning convalescence may be as low as 65 mm. hg. i have frequently seen hypotension of 80 mm. this is common. meningitis is the only acute infectious disease in which the blood pressure is more often high than low. this is accounted for by the increased intracranial tension. following large hemorrhages the blood pressure is reduced. in venesection the withdrawal of blood may not affect the blood pressure. the procedure is done to relieve overdistension of the heart. in pleurisy with effusion and in pericarditis with effusion there is hypotension. collapse, whether from poisoning by drugs or as the result of dysentery, cholera, or profuse vomiting from whatever cause, reduces the blood pressure. in cachectic states, such as cancer, the blood pressure is low. general wasting of the whole musculature includes that of the heart and the heart muscle shows the condition known as "brown atrophy." a most interesting and important condition in which hypotension occurs is pulmonary tuberculosis. haven emerson has recently gone over the whole subject in a careful piece of work and his summary is as follows: "hypotension or subnormal blood pressure is universally found in advanced pulmonary tuberculosis, in which condition emaciation may play a part in its causation. hypotension is found in almost all cases of moderately advanced tuberculosis, or in early cases in which the toxemia is marked except when arteriosclerosis, the so-called arthritic or gouty diathesis, chronic nephritis, or diabetes complicate the tuberculosis and bring about a normal pressure or a hypertension. occasionally the period just preceding a hemoptysis or during a hemoptysis may show hypertension in a patient whose usual condition is that of hypotension. "hypotension has been found by so many observers in early, doubtful or suspected cases with or before physical signs of the disease in the lungs, and is considered by competent clinicians so useful a differential sign between various conditions and tuberculosis, that it should be sought for as carefully as it is the custom at present to search for pulmonary signs. "hypotension when found persistently in individuals or families or classes living under certain unhygienic conditions should put us on our guard against at least a predisposition to tuberculosis. most unhygienic conditions, overwork, undernourishment and insufficient air, are of themselves causes of a diminished resistance, and it seems likely that a failure of normal cardiovascular response to exercise or change of position may be found to indicate this stage of susceptibility, especially to tuberculous infection. "... hypotension, when it is present in tuberculosis, increases with an extension of the process. recovery from hypotension accompanies arrest or improvement. return to normal pressure is commonly found in those who are cured. continuation of hypotension seems never to accompany improvement. prognosis can as safely be based on the alteration in the blood pressure as on changes in the pulse or temperature...." there are a few drugs which lower the blood pressure, but, as a rule, their effects are more or less transitory. we know of no drug, unless it be iodide of potassium, which has the property of causing changes in the blood (decrease in viscosity?), which tends to reduce the blood pressure when it is excessive. this drug fails us many times. some drugs which influence the blood pressure =pressure raisers= adrenalin, when injected directly into a vein or deep into the muscles. the action is transitory. caffeine, preferably in the form of caffeine-sodium-benzoate. a good drug. strychnine, which does not act directly but seemingly through the higher centers. ergot, somewhat uncertain. nicotine, not used therapeutically. camphor, used in sterile olive oil and injected deeply into the muscles. digitalis, when the cardiac tone is low and decompensation is present. its action is prolonged but slow. injections of the infundibular portion of the pituitary body. not in use clinically. =pressure depressors= nitroglycerine and amyl nitrite, action transitory but rapid. sodium nitrite and erythrol tetranitrate. action somewhat more prolonged. aconite, veratrum viride, chloral, etc. these depress the heart. purgatives, drastic and hydragogue. potassium and sodium iodide may lower blood pressure. when they do, the action is prolonged. diuretin and theocin-sodium-acetate. =venous pressure= comparatively little work has been done upon the determination of the pressure in the veins in man. it is conceivable that this procedure may, at times, be of great value. a number of attempts have been made to measure the venous pressure by compressing the arm veins and noting on a manometer the force necessary to obliterate the vein. as the pressure is so slight, water is used instead of mercury, and readings have been given in centimeters of water. [illustration: fig. 33.--apparatus for estimating the venous blood pressure in man, devised by drs. hooker and eyster. the small figure is the detail of the box b. see explanation in text.] in the apparatus shown in the figure (fig. 33), drs. hooker and eyster succeeded in making estimations of the venous pressure. the box _b_ is held in position by the tapes _a_, so that the vein is visible through the rectangular opening in the thin rubber covering the bottom. the box is connected with the water manometer _g_, by a rubber tube, from which a t-tube enters the rubber bulb _e_. when the bulb _e_ is compressed between the plates _d_, by the coarse thumbscrew _c_, air is forced into the box _b_, exerting a pressure on the vein lying exposed beneath. this pressure is transmitted directly to the manometer =g=, and may be read off in centimeters of water on the accompanying scale. the veins of the back of the hand are used and there must be no obstruction between them and the heart. the rubber-covered box is accurately and lightly fitted over a vein and pressure made until it is obliterated. by measuring the distance above or below the heart level that the hand was when the observation was made, and subtracting or adding these figures to the manometer reading, we obtain the venous pressure at the heart level. eyster has modified this instrument so that it is now much simpler to operate. he uses a small glass cup with a flaring edge and a diameter of about 2 cm. this is sealed to the skin directly over a vein on the back of the hand by means of collodion. the stem of the cup has a rubber tube leading to a small hand bulb and to the manometer tube which contains colored water. slight compression of the hand bulb obliterates the vein which can be seen through the glass cup. the pressure in centimeters of water is then read off. (fig. 34.) the principle is the same as in the earlier instrument, but the application is easier. [illustration: fig. 34.--new venous pressure instrument. (after eyster.)] practically hooker and eyster found that the normal variation in healthy subjects was from 3 to 10 cm. of water. the pressure rose in cases of decompensated hearts with dyspnea and venous stasis, and returned to normal with improvement in the condition of the patient. it might be possible with this instrument to foretell an oncoming decompensation by the rise in venous pressure. the venous pressure may also be estimated roughly by slowly elevating the arm and noting the instant at which a particular vein collapses. by measuring the height of the vein above the heart some idea may be obtained of the pressure within the right auricle. =the pulse= there is nothing characteristic about the pulse of a person suffering from arteriosclerosis, except it be the difference in the pulse of high tension and of low tension. the pulse of high tension has a gradual rise, a more or less rounded apex, and the dicrotic wave is slightly marked and occurs about half-way down on the descending limb. in arteriosclerosis with low tension the radial artery is usually so rigid that very little pulse wave can be obtained. the general form of a low tension pulse is a sharp upstroke, a pointed summit, and a secondary wave on the base line, which corresponds to the dicrotic wave. such a pulse can be easily palpated, and is known as a dicrotic pulse. however, such a pulse can occur only when the artery still retains all or a large part of its elasticity; hence in arteriosclerotic low tension we would never see such a pulse as the typical dicrotic. =the venous pulse= it would carry us too far to discuss fully the character of the venous pulse, but a brief summary of the essential features of the normal venous pulse is presented. the venous pulse is a term used to express the tracing obtained from the internal or external jugular vein at the root of the neck. normally a very characteristic curve is produced, which can be readily analyzed into a series of waves corresponding to the fluctuations in the cardiac cycle. to understand these waves and their values, the accompanying figure is helpful. (fig. 35.) [illustration: fig. 35.--semidiagrammatic representation of the events in the cardiac cycle: jug., pulse in the jugular vein; aur., contraction of auricle; v. pr., intraventricular pressure; pap. m., contraction of the papillary muscles; car., carotid pulse. below are given the times of occurrence of the heart sounds and of the opening and closing of the heart valves. (after hirschfelder.)] bachmann summarizes the normal waves in the venous pulse tracing as follows: "the physiological or so-called venous pulse consists of three positive and three negative waves, bearing a more or less definite relation to the events of the cardiac cycle, and having their origin in the various movements of the chambers and structures of the right heart. the first positive wave (_a_) is presystolic in time, and is due to the contraction of the auricle, causing a slowing of the venous current and producing a centrifugal wave through a sudden arrest of the inflowing blood. the second positive wave (_s_) is presystolic in time, and originates in the sudden projection of the tricuspid valve into the cavity of the auricle during the quick, incipient rise in the intraventricular pressure occurring in the protosystolic period. the third positive wave (_v_) occurs toward the end of ventricular systole. it consists of two lesser waves separated by a shallow notch. the factors entering into its formation are the relaxation of the papillary muscle at a time when the intraventricular is still higher than the intraauricular pressure, resulting in an upward movement of the tricuspid leaflets and a return of the auriculoventricular septum to its position of rest. "the first negative wave (between positive wave _a_ and _s_) is due to the relaxing auricle. the second negative wave (_af_) occurs during the diastole of the auricle. it is due to the dilatation of its walls, to the displacement of the auriculoventricular septum toward the apex occurring at the time of ventricular systole, and to the pull of the papillary muscles on the tricuspid valve leaflets. the third negative wave (_vf_) appears during ventricular diastole and in the common pause of the heart chambers. its cause is found in the passage of the blood from the auricle into the ventricle. it is somewhat modified possibly by the continual ascent of the auriculoventricular septum and by a wave of stasis due to the accumulation of blood coming from the periphery." (fig. 36.) [illustration: fig. 36.--simultaneous tracings of the jugular and carotid pulses showing normal waves in the venous pulse and relation to carotid pulse. (after bachmann.)] hirschfelder has described another wave which he calls the "h" wave, which is due to the floating up of the tricuspid valve by the blood in the ventricle before the complete filling of the ventricle following the auricular systole. (fig. 37.) [illustration: fig. 37.--jugular and carotid tracing from a normal individual with a well-marked third heart sound showing a large "h" and a smaller pre-auricular wave "w." ? indicates a small wave in mid-diastole following the "h" wave, occasionally found though perhaps an artefact. (after hirschfelder.)] =the electrocardiogram= in the past few years an immense amount of work has been done by numerous observers on the changes in the electrical potential of the various portions of the heart during contraction. the very elaborate and delicate electrocardiograph with the string galvanometer devised by einthoven is used. it has been definitely determined that the impulse to cardiac contraction originates in the sinus node, a collection of differentiated nerve cells situated at the junction of the superior vena cava with the right auricle. from there the impulse travels in certain fibers in the interauricular wall, passes through another node, the auriculoventricular or tawara node, situated in the auricular wall just above the auriculoventricular ring, thence via the y-bundle, or bundle of his to the ventricles. this sequence is orderly, regular, and normally invariable. (fig. 38.) [illustration: fig. 38.--right side of the heart showing diagrammatically the distribution of the two vagus nerves to different parts of the viscus. the impulse to contraction originates at the sino-auricular node and passes over the wall of the auricle to tawara's node, and thence over his' bundle across the auriculoventricular septum to be distributed throughout the ventricular wall. if the upper, sino-auricular, node is damaged, or if its impulses fail to get across the wall of the auricle, tawara's node acts in its place to start off the ventricle. if a lesion at the base of the mesial segment of the tricuspid valve damages his' bundle, so that tawara's node is cut off from the ventricle, then the ventricle may originate its own impulses to contraction. (hare's practice of medicine.)] the sino-auricular (s-a) node is the most irritable portion of the heart, it is endowed with the greatest amount of rhythmicity as well. it is under the control of the vagus nerve. its inherent rate of rhythmicity is probably more rapid than the usual numbers of impulses per minute, but it is inhibited by the vagus. paralysis of the vagus endings increases the rate of impulse formation and therefore the rate of the heart. the electrocardiogram is a graphic representation on a photographic film or sensitive bromide paper of the changes of electrical potential during muscular activity. the lines are made by the highly magnified string of the galvanometer as it moves across the slit in the photographic apparatus in response to the induction currents set up in the heart magnified by the special galvanometer. the record is made in three so-called leads. lead i the electrodes are attached to right arm and left arm. lead ii the electrodes are attached to right arm and left leg. lead iii the electrodes are attached to left arm and left leg. a series of regular figures is normally obtained in which are depressions and elevations and regular spacing of these elevations and depressions. the waves so-called have been arbitrarily designated _p_, _q_, _r_, _s_, _t_. there is some difference in the three leads. "the wave _p_ is positive in _all leads_. _p_ to _r_ interval varies slightly in the _three leads_. all the waves of _lead ii_ are greater than those of _leads i_ and _iii_. the wave _r_ is positive in _all leads_. _t_ is usually positive in _all leads_, but is occasionally negative in lead iii. even in normal individuals there is a considerable range of variation in the electrocardiogram which is within the limits of the normal." (hart.) (fig. 39.) [illustration: fig. 39.--normal electrocardiogram. (after hart.)] the _p_ wave is admitted to be the wave of auricular contraction. _q_, _r_, _s_, is the ventricular complex caused, it is thought, by the current passing over the ventricles. _t_ wave is not yet definitely settled. it has been thought by some that it represented actual ventricular contraction and its height and shape had some meaning in heart force. this is denied by others. hart defines it as "the final activity of the ventricle." the _t_ wave is usually increased in size during exercise. the _p-r_ interval is almost the most important feature of the tracing. it is the actual conduction time in fractions of a second of the impulse from s-a node to the ventricles. normally this is about 0.2 second or slightly less. much that was hoped for from the electrocardiograph in the clinic has not been forthcoming. its greatest value is in states of abnormal conductivity, such as various grades of heart block, extrasystoles, whether originating in auricles or in either ventricle, abnormalities of rhythm, as flutter and fibrillation. it has, however, aided materially in the intelligent interpretation of many phenomena heretofore not well understood, and has enormously increased our knowledge of the physiology and pathologic physiology of the heart. it is not possible to enter farther into the subject here. this brief discussion must suffice. the reader is referred to works on this subject in connection with diseases of the heart. chapter iv important cardiac irregularities associated with arteriosclerosis arteriosclerosis of the aorta, of the coronary arteries, or of both, is practically always found in cases dying of various cardiac irregularities other than those the result of rheumatic cardiac lesions. it is not that arteriosclerosis causes the cardiac lesions (although the thickening of the walls of the coronary arteries does interfere mechanically with the nutrition of the heart muscle), but the arteriosclerosis is a part of the tissue reaction in the arteries to some set of causes affecting the whole body. it is true when one boils down the question to its last analysis, general arteriosclerosis may mechanically so interfere with the blood supply to tissues that the tissue is thrown out of function either in the reduction or even loss of function. so it may be that occasionally the arteriosclerosis in the arteries supplying the heart is really responsible for the cardiac irregularity. the past few years have been fruitful ones in increasing our knowledge of the various irregularities of the heart. we can do no more than sketch briefly some of them in relation to arteriosclerosis. the chief irregularities are (1) auricular flutter, (2) auricular fibrillation, (3) ventricular fibrillation, (4) auricular extrasystole, (5) ventricular extrasystole, (6) heart block, partial or complete. =auricular flutter= auricular flutter is an abnormal rhythm characterized by very rapid, but rhythmic auricular contractions usually 250 to 300 per minute. the auricular contractions are so rapid that the ventricle can not respond, so that an electrocardiagram of a heart in such a state (fig. 40) shows the ventricle beating regularly but at a much slower rate than the auricle. [illustration: fig. 40.--(after hart.)] the majority of cases exhibiting this peculiar rhythm are over 40 years of age. in many cases sclerosis of the coronary arteries as a part of general arteriosclerosis has been found. auricular flutter can be suspected when the pulse is regular or not particularly irregular and a fluttering, rapid pulsation is seen in the jugular vein on the right side. one can only be sure of the condition by making graphic records of the heart. attacks usually come on suddenly and may disappear as suddenly, suggesting paroxysmal tachycardia. the patient feels a commotion in his chest, dyspnea, precordial distress, etc. the attack may last for weeks or months, in which case the patient may carry on his usual work but be conscious of palpitation in his chest. one may safely assume that the flutter is a sign of a failing myocardium and sooner or later the heart will pass to the graver stage of auricular fibrillation. =auricular fibrillation= in this condition the auricle is widely dilated and over its surface are countless twitchings of individual muscles giving to the auricle the appearance of a squirming bunch of worms. such a condition may be readily produced in a dog's exposed heart by direct faradization of the auricle. it should be seen by every physician in order fully to appreciate the passive, dilated sac part which the auricle plays when in such a state. there is no auricular wave on the electrocardiogram (figs. 41 and 42) only a series of fine tremulous lines, and the ventricles beat irregularly with many dropped beats and variations in the size and force of individual beats. extrasystoles are also frequent. the heart is absolutely irregular. such a condition is readily recognizable as the state of broken compensation. graphic records are not essential as in auricular flutter to establish the condition. inspection of the root of the neck for jugular pulsations and examination of the pulse with the patient's evident dyspneic, cyanotic, edematous condition settles the diagnosis. [illustration: fig. 41.--electrocardiogram showing auricular fibrillation in leads i (upper) and ii (middle and lower). (courtesy of dr. g. c. robinson.)] [illustration: fig. 42.--auricular fibrillation. (after hart.)] in no case of auricular fibrillation is the heart muscle free from extensive fibrous changes. these may be the result of general arteriosclerotic changes or may result from toxic changes. it is the general consensus of opinion that auricular fibrillation may persist for months or even years. some hold that the state of perpetual irregular pulse is associated with auricular fibrillation. if that is true, then auricular fibrillation may last for many years. patients may go about their work but always live with the imminent danger of a sudden dilatation of the ventricle and symptoms of acute cardiac decompensation. in these cases the blood pressure is of particular interest. it is often stated that the blood pressure is lowered as compensation returns and digitalis has exhibited its full action. as a matter of fact this statement needs some modification. if one takes the highest pressure at the strongest beat, which may be only one in a dozen or more, that may be true, but that does not represent the action of the much embarrassed heart. we know that the circulation is much interfered with, that there is hypostatic congestion, that the mass action is slow. the pulse pressure is greatly disturbed and the head of pressure which should force the blood to the periphery is so little that the circulation almost ceases. a count of the cardiac contractions heard with the stethoscope and a count of the pulse shows a great discrepancy in number. this has been called the "pulse deficit" (hart). in order to arrive at the true average systolic pressure the following procedure is done. "the apex and radial are counted for one minute, at the same time by two observers, (if possible) then a blood pressure cuff is applied to the arm, and the pressure raised until the radial pulse is completely obliterated; the pressure is then lowered 10 mm., and a second radial count is made; this count is repeated at intervals of 10 mm. lowered pressure until the cuff-pressure is insufficient to cut off any of the radial waves (between each estimation the pressure on the arm should be lowered to zero). from the figures thus obtained the average systolic blood pressure is calculated by multiplying the number of radial beats by the pressures under which they came through, adding together these products and dividing their sum by the number of apex-beats per minute, the resulting figure is what we have called the 'average systolic blood pressure.'" (fig. 43.) [illustration: fig. 43.--the shaded area represents the pulse deficit; the upper edge is the apex rate, the lower edge the radial rate. the broken line indicates the "average systolic blood pressure." (compare these values with the figures at the bottom of the chart, which show the systolic blood pressure determined by the usual method.) (after hart.)] for example: "b. s., april 29, 1910, apex 131; radial, 101; deficit, 30. brachial pressure radial count 100 mm. hg. 0 90 mm. 13 13 x 90 = 1170 80 mm. 47 13 = 34 x 80 = 2720 70 mm. 75 47 = 28 x 70 = 1960 60 mm. 82 75 = 7 x 60 = 420 50 mm. 101 82 = 19 x 50 = 950 --- apex = 131) 7220 --- average systolic blood-pressure 55 plus b. s., may 11, 1910, apex 79; radial, 72; deficit 7. brachial pressure radial count 120 mm. hg. 0 110 mm. 44 44 x 110 = 4840 100 mm. 64 44 = 20 x 100 = 2000 90 mm. 72 64 = 8 x 90 = 720 --- apex = 79) 7560 --- average systolic blood-pressure 95 plus" the diastolic pressure in these cases can not be determined except approximately. this may be done by using an instrument with a dial and noting the pressure where the oscillations of the dial hand show the maximum excursion. the diastolic pressure is not at all important under such conditions of acute cardiac breakdown. it would make no difference in treatment whether the case was one of pure cardiac disease or one of the hypertension groups. after the heart has rallied and the circulation is reestablished, then a careful determination of the diastolic pressure can be made and the prognosis will rest on what is found at the compensated stage. =ventricular fibrillation= ventricular fibrillation as its name implies, is fibrillation of the ventricle analogous to that of the auricle, but the condition is rarely observed as it is incompatible with life. it has been shown that hearts at the time of death at times enter a state of fibrillation of the ventricles and that cases of sudden death may be due to this condition. recently g. canby robinson[12] has seen and made electrocardiograms of a case of ventricular fibrillation. (fig. 44.) the case was that of a woman forty-five years old, "who had a series of attacks of prolonged cardiac syncope, closely resembling stokes-adams syndrome, from which she recovered." during an attack of unconsciousness in which there was no apex beat for about four minutes, the electrocardiogram was taken. following this the tracings showed an almost regular heart beating at the rate of 85 to 100 per minute. the patient had three convulsions and died with edema of lungs about 30 hours after the attack of ventricular fibrillation. [12] robinson, g. c., and bredeck, j. f.: arch. int. med., 1917, xx, 725. [illustration: fig. 44.--upper curve. record obtained during period of cardiac syncopy at 2:48 p.m., lead ii. lower curve from dog. ventricular fibrillation observed in the exposed heart. lead from right foreleg and left hind leg. (courtesy of dr. g. c. robinson.)] autopsy revealed chronic fibrous endocarditis of aortic and mitral valves, arteriosclerosis, bilateral carcinoma of the ovaries, and signs of general chronic passive congestion. it is possible that the syncopal attacks in this case were the result of sclerosis of the vessels supplying the heart muscle although careful microscopical examination did not throw much light on the ultimate cause. =extrasystole= whenever there is a dropped beat or an intermittent pulse one may be sure that it is the result of an extrasystole. such extrasystoles are produced in the ventricle at some point other than the regular path of conduction of impulses. the extrasystole may have its origin in either the auricle or the ventricle. if there is auricular extrasystole it can not usually be recognized except by graphic methods. (fig. 45.) the ventricular extrasystole on the contrary is commonly seen and readily recognized. most of those seen in the clinic have their origin in some part of the ventricular wall. their two characteristics are that they occur too early and that they are followed by a pause longer than the normal diastolic pause. (fig. 46.) [illustration: fig. 45.--electrocardiogram showing auricular extrasystoles (p). (courtesy of dr. g. c. robinson.)] [illustration: fig. 46.--electrocardiogram showing ventricular extrasystole. heart rate 56-60 beats per minute. note that diastolic pause in which extrasystole occurs is practically equal to two normal diastolic pauses. (courtesy of dr. g. c. robinson.)] when one listens over the chest to a heart when extrasystoles are occurring, one suddenly hears a weak beat which has taken place rather too early after the previous systole to be strong enough to effect the opening of the aortic valves. consequently there is no pulse, the blood does not move, and that beat is lost to the circulation. moreover, when the next regular stimulus comes from the s-a node it finds the ventricle in a refractory condition, having just ceased a contraction, and it is not until the next sinus impulse that the ventricle responds normally. (fig. 46.) patients who have occasional extrasystoles will say that all of a sudden the heart turns upside down in the chest. sometimes there is slight sharp twinge of pain. patients are at times quite alarmed about their condition. provided there is no evidence of gross myocardial lesion, the extrasystole itself is of no great significance. while many cases showing pathologic causes for extrasystoles have more or less marked arteriosclerosis, there are other states in which no arteriosclerosis is found where the extrasystole is present. =heart block= as heart block occurs frequently in cases characterized by extensive arteriosclerosis, a brief discussion of the essential features will be given. it is, however, probable that arteriosclerosis is not the cause of any of the cases of heart block directly, but it is only a result of the same etiological conditions which produce the lesion or lesions which result in heart block. we may define heart block as the condition in which the auricles and ventricles beat independently of each other. there may be delayed conduction (fig. 47), partial (fig. 48), or complete heart block (fig. 49). in the former there are ventricular silences, during which the auricles beat two, three, four, five, even up to nine times, with only one ventricular contraction. it is believed by most physiologists that the essential factor in the production of heart block is an interference in the conduction of impulses from the auricles to the ventricles through the band of tissue known as the auriculoventricular bundle. [illustration: fig. 47.--electrocardiogram showing delayed conduction (lengthening of p-r interval). these p-r intervals are quite regular. when irregular there is apt to be extrasystole of ventricle or occasional blocking of impulse going to ventricle. (courtesy of dr. g. c. robinson.)] [illustration: fig. 48.--electrocardiogram showing partial heart-block in the three leads. note the variability of p-r interval calculated in seconds in lead ii. (courtesy of dr. g. c. robinson.)] [illustration: fig. 49.--complete heart block. (courtesy of dr. g. c. robinson.)] the bundle of muscles described by his in 1905, connecting the auricles and ventricles, has been definitely shown to be the path through which impulses having their origin in the orifices of the great veins pass to the ventricles. the situation and size of this bundle has been thus described in man by retzer: "when viewed from the left side, the bundle lies just above the muscular septum of the ventricles and below the membranous septum. in some hearts the muscular septum is so well developed that it envelops the bundle. it is then difficult to find, but occasionally it can be seen directly by means of transmitted light. from the left side the bundle can be followed no farther posteriorly than the right fibrous trigone, for here the connective tissue becomes so dense that it is difficult to dissect it away. the impression is, therefore, received that this mass of connective tissue forms the insertion of the bundle. the bundle may be followed anteriorly until it becomes intimately mixed with the musculature of the ventricles. "when viewed from the right side of the heart, the bundle can not be seen, because it is covered by the mesial leaflet of the tricuspid valve, whose line of attachment passes obliquely over the membranous septum. then, if the endocardium is removed from the posterior part of the septum of the auricle up to the membranous septum, the posterior part of the auriculoventricular bundle will be exposed. if, in addition, the membranous septum be removed, the bundle may be traced from the point to which it could be followed when viewed from the left side as it passes posteriorly over the muscular septum. in the region of the auriculoventricular junction it loses its compactness, the fibers divide, and the bundle seems to fork. one branch passes into the superficial part of the valve musculature which descends from the auricles, and the other branch passes directly into the musculature of the auricle. "briefly, the auriculoventricular bundle runs posteriorly in the septum of the ventricles about 10 mm. below the posterior leaflet of the aortic semilunar valves; with a gentle curve it passes posteriorly just over the upper edge of the muscular septum and sends its fibers into the musculature of the right auricle and of the auricular valves. in the heart of the adult the bundle is 18 mm. long, 2.5 mm. wide, and 1.5 mm. thick." (erlanger.) all normal impulses have their origin in the sino-auricular node at the junction of the superior vena cava with the right auricle (fig. 50). from there the impulse travels in the wall of the auricle in the interauricular septum to the node of tawara or a-v node (fig. 51), thence through the bundle of his to be distributed to the fibers of the right and left ventricles. this sequence is orderly and perfectly regular. [illustration: fig. 50.--showing alternating periods of sinus rhythm and auriculoventricular rhythm. (after eyster and evans.)] [illustration: fig. 51.--period of auriculoventricular or "nodal" rhythm following exercise in sitting posture. (after eyster and evans.)] it has also been shown that the independent auricular and ventricular rates vary somewhat, that of the auricle being in general faster than that of the ventricle. a strip of mammalian ventricle placed outside of the body in proper surroundings will begin to beat automatically at the rate of about 40 beats a minute. experimentally various grades of heart block have been produced in the dog's heart by more or less compression of the bundle at the a-v ring. the block may be partial, when two to nine auricular beats occur to every one of the ventricle, up to absolute complete block when the auricles and ventricles beat independently of one another. in any stage of partial block, pressure on the vagus nerve in the neck produces certain specific changes. (fig. 52.) robinson and draper[13] have found qualitative differences in the two vagi. the right vagus sends most of its fibers to the s-a node (fig. 53) and has a more evident influence on the rate and force of the cardiac contractions. the majority of fibers from the left vagus are distributed to the a-v node so that its most evident action is upon the conductivity of the impulse. pressure then on the right vagus will have a tendency to slow the whole heart. pressure on the left vagus will have a tendency to prolong the p-r interval until even complete block occurs. even when the heart block is complete, stimulation of the accelerator nerve, as a rule, increases the rate of both auricles and ventricles. [illustration: fig. 52.--influence of mechanical pressure on the right vagus nerve. (after eyster and evans.)] [illustration: fig. 53.--schematic distribution of right and left vagus. (after hart.)] [13] jour. exper. med., 1911, xiv, 217. if the block is functional, depending upon some temporary overstimulation of the vagus nerve, atropin, which paralyzes the endings of the vagus, will naturally lift the block. if the block is due to some actual lesion of the bundle of his, such as fibrosis, gumma, or other lesion, then atropin will have no influence to terminate the block. in this manner we are able to distinguish between functional and organic heart block. chapter v blood pressure in its clinical applications it is well to bear constantly in mind the point made over and over in this work, that blood pressure is only one of many methods of acquiring information. he who worships his sphygmomanometer as a thing apart and infallible will sooner or later come to grief. judgment must be used in interpreting changes in blood pressure just as judgment is essential in properly evaluating any instrumental help in diagnosis. one must not forget the personal equation which enters into even accurate instrumental recording in medicine and surgery. in this chapter there will be no attempt to quote largely from what others have said or thought. every one has his own opinion as to the value of certain methods after he has worked with them for a long time. the ideas here expressed, except in cases where no opportunity has offered to make personal studies, are those gathered from personal experience. =blood pressure in surgery= careful estimation of the blood pressure in surgical cases has, at times, great value. in all surgical diseases the most important fact to know is not the systolic pressure, but the pulse pressure. if the pulse pressure keeps within the range of normal, does not drop much below 30 mm. in an adult, then so far as we can tell the circulation is being carried on. when the systolic pressure is gradually falling and the diastolic remains the same, the circulation is failing and unless the pulse pressure can be established again the patient will die. again we see the value of the pulse pressure. all prolonged febrile diseases tend to produce a lowering of the blood pressure picture. the diastolic does not fall to the same extent as the systolic so that there is a pulse pressure smaller than normal. this is to be expected from what we know of the general depression of the circulation in fevers. the blood pressure reading is only a graphic record of what we have long known, and enables us from day to day accurately to measure the general circulation. =head injuries= it was claimed that in fracture of the skull or in concussion much could be gained by frequent estimations of the blood pressure. this seemed probable in the light of experiments on compressing the brains of dogs by the use of bags inserted through trephine openings (cushing). in the clinic, however, it has not been found of any material value. it has a value in differentiating a simple fracture, let us say, from a case of uremia which is picked up on the street with a bump on the head. there the high pressure usually found would at once direct attention to the kidneys and the newer methods of blood examination would at once settle the question. naturally uremics may also have skull fracture. there the diagnosis would be complicated. a decompression done at once would be indicated. if the skull fracture happened in a uremic, the decompression would probably do no harm. in fact, there are some who advise decompression for uremia. =shock and hemorrhage= in shock the blood pressure picture is low but the pulse pressure drops to abnormally low figures. it seems to me that the blood pressure instrument has its greatest value in surgery in the warning it gives to the operating surgeon in cases of impending shock. it is well known that the first effect of ether, the commonly used anesthetic, is to raise the blood pressure and quicken the pulse rate. the whole blood pressure picture is at first elevated (fig. 54). soon the whole pressure falls slightly but continues at a higher level than normal. the diastolic pressure drops back nearly to normal and the increased pulse pressure is due almost entirely to the slight rise in the systolic pressure. now the whole duty of the anesthetist is to administer the ether so that this ratio of systolic and diastolic is maintained throughout the operation. warning comes to him of impending shock before it comes to any one in the neighborhood (fig. 55). any sudden change in the pressure is a signal for increased watchfulness. should the pressure all at once drop he can immediately notify the surgeon and institute measures to resuscitate the patient. [illustration: fig. 54.--blood pressure record from a normal reaction to ether. note that the systolic and diastolic rise and fall together. at the end of the anesthetization the pulse pressure is practically the same as at the beginning. compare this with the record in fig. 55, where the operation had to be discontinued on account of the onset of shock.] [illustration: fig. 55.--beginning of operative shock. chart showing the method of recording blood pressure during operation. note that the pulse and respiration show no remarkable changes, but the blood pressure steadily fell, the systolic more than the diastolic so that the pulse pressure was gradually reaching the danger point. further work on this case was stopped following the warning given by the blood pressure. the patient was returned to the ward and a week later anesthesia was again given, the operation was completed, and the patient had a satisfactory convalescence.] a method which is widely used is as follows: the anesthetist wraps the cuff of one of the dial instruments around the patient's arm, and arranges the dial so that it can easily be seen by him at all times. this does not in any way interfere with the work of the surgeon. over the brachial artery below the cuff is the bell of a binaural stethoscope held in place by the strap attachment now on the market. the tubes of the stethoscope are long enough to reach conveniently to the ear pieces. a watch is pinned to the sheet of the table. he has a chart, as illustrated (fig. 56) on a board and makes a dot in every space for five minute intervals. by joining the lines a curve is obtained which tells at a glance what the circulation is doing. i feel sure that more attention and care exercised on the part of the anesthetist would be the means of conserving many lives lost from shock following operation. [illustration: fig. 56.--showing method of using blood pressure instrument during operation without interfering with the operator or assistants. sheet thrown back to show cuff on arm of patient. anesthetist has chart on table beside him, dial pinned to pad in full view, bulb near hand. extra tubing must be put on the blood pressure instrument.] a sudden drop in the pressure picture may mean a large hemorrhage. the gradual return of the pressure picture means that the vasomotor mechanism has acted to keep up the pulse pressure. should the diastolic pressure continually fall, it may mean that the hemorrhage is still taking place (wiggers). =blood pressure in obstetrics= one might affirm almost without fear of contradiction that the constant determination of blood pressure during pregnancy is more important than the examination of the urine. within recent years a number of observers having access to a large material, have given the results of their findings. there is a striking unanimity of opinion, although now and then a difference in minor details. the blood pressure should be taken frequently during pregnancy. the usual and highly essential precautions in taking pressure in general apply most particularly in these cases. towards the end of pregnancy the pressure should if possible be taken daily and oftener if necessary. pressure in women is usually below 120 mm. many patients have a temporary rise in blood pressure during pregnancy, due oftenest to constipation, without developing other symptoms. this is common to all conditions and has no significance. some think that an abnormally low pressure, that is, a systolic below 90 mm., suggests that the patient is likely to react unduly to the strain of labor. this is denied by others. among 1000 cases (irving) the pressure was below 90 in only one case. a gradually rising pressure precedes albuminuria, as a rule. if there is albumin without change in pressure the albumin may usually be disregarded. some think that a pressure over 130 mm. systolic should be carefully watched. the danger limit is set by some at 150 mm. if the blood pressure from the very first is high, it may mean only that that was the patient's normal pressure. this calls for increased watchfulness. it is held by some that high blood pressure favors hemorrhage and probably explains the hemorrhagic lesions in the placenta and some viscera in eclampsia and albuminuria. all are agreed that the most significant change is the gradual but sure rise from a low pressure. when this is combined with albuminuria the danger of toxemia is imminent. the high blood pressure in those under thirty years of age seems to be a more certain sign of approaching toxemia than the same pressure in those older. the pressure falls within a few days to its normal after delivery in the toxic cases. although the emesis gravidarum is held to be a sign of a toxemia of some unknown nature, the blood pressure is never raised even in the pernicious form. =infectious diseases= in all infectious diseases the blood pressure tends to be lower than normal. during chills the systolic may rise to great height due to the violent muscular contractions. we found the blood pressure of great value in giving information concerning the circulation. again we repeat that it is not the systolic alone or the diastolic alone but the pulse pressure which we wish to keep informed about. in pneumonia we have tried out gibson's law only to discard it. this so-called law is that in pneumonia the systolic pressure in millimeters should remain above the figure for the pulse rate. when the figure in mm. of pressure is equalled by or exceeded by the pulse rate the prognosis is grave. in typhoid fever we have made many estimations at various stages of the disease. we can only say that the pressure picture tends to fall during the course. the systolic falls more than the diastolic so that it is not uncommon to see pulse pressures of 20 mm. at the beginning of convalescence in spite of the high caloric feeding practiced. at the time of perforation the systolic pressure may be raised. this is only the reflex from the initial pain. soon the pressure falls and if peritonitis sets in, the pressure is exceedingly low and the pulse pressure gradually falls until the circulation can no longer be carried on. in large hemorrhage the pressure suddenly falls. if only one hemorrhage has occurred a gradual rise takes place, but the general pressure picture remains at a lower level for days, gradually returning where it was before the hemorrhage. in beginning failure of the circulation we found elevation of the foot of the bed about nine inches to be of such value that we felt there must be some increase in blood pressure. numerous readings were made covering a period of several months. although we felt certain that the circulation was improved, we rarely needed cardiac stimulation, we never could prove any increase of blood pressure with the sphygmomanometer. in all infectious diseases there is no help offered by blood pressure estimations in diagnosis. the sole and important use is that of keeping track of the circulation. =valvular heart disease= no rules can be laid down for blood pressure in valvular heart disease. aortic stenosis, the rarest of the valvular lesions, is practically always accompanied by high pressure picture. mitral stenosis on the contrary usually shows a low pressure picture. mitral insufficiency may show an exceedingly low picture or an exceedingly high picture. aortic insufficiency also may be accompanied by a high systolic or by a normal systolic pressure. it depends on the etiology. practically all the rheumatic cases have low pressure, the syphilitic cases have a high pressure. it is characteristic of all cases of aortic insufficiency that the diastolic pressure is low, even as low as 30 mm. the pulse pressure is invariably high. usually there is no difficulty in determining the diastolic pressure. the intense third tone suddenly becomes dull at the point of diastolic pressure and frequently the dull sound can be distinctly heard over the artery down to the zero of the scale. if difficulty is found in reading the diastolic as the pressure is reduced, the estimation may be reversed and the pressure gradually increased from zero to the point where the dull tone suddenly becomes loud and clear. these points always coincide. =kidney diseases= this has already been discussed somewhat fully in chapter iii and will receive more consideration later. it might be remarked in passing that in a case of seeming coma where albumin is found in the urine but where the blood pressure is low or normal, i have found at autopsy in several cases pyonephrosis and not chronic nephritis. the blood pressure may be useful in differentiating uremic coma from the coma of pyonephrosis. also in the cases of coma with anasarca, either the acute, subacute or chronic form the blood pressure is not raised as a rule. other diseases of the kidney, as tuberculosis, cancer, infection with pyogenic organisms, are not accompanied with any notable changes in blood pressure. =other diseases, liver, spleen, abdomen, etc.= blood pressure is only of value in the above diseases in affording information concerning the state of the circulation. there is nothing characteristic about the pressure in any of these diseases. chapter vi etiology the causes of arteriosclerosis are many and varied. no two persons have the same resisting power toward poisons that circulate in the blood. some go through life exposed to all the infectious diseases without ever becoming infected, while others fall easy victims to every disease that comes, no matter how careful they may be, and it is quite the same in regard to the resistance of the arterial tissues. if the tubing is of first class quality and the individual does not place too much strain on it, he may live to the biblical three-score years and ten, and possess arteries which have undergone such slight changes that they are not palpable. such a person is, however, the exception. on the other hand, if the tissue is of poor quality, even the ordinary wear and tear of life causes early changes in the vessels, and a person of forty may have hard arteries. we have described in a previous chapter the changes which normally occur in the arteries as age advances. an artery that is normal for a man of fifty years would be distinctly abnormal for a boy of fifteen. two broad divisions of arteriosclerosis may be made: (1) congenital, or the result of inherited tendency; (2) acquired. =congenital form= when dr. o. w. holmes was asked how to live to the age of seventy, he replied that a man should begin to pick his ancestors one hundred years before he was born. our parents determine the character of the tissues with which we start in life, and this determines our general resistance. we might properly speak of congenital arteriosclerosis where the affected individual had poor arterial tissue with which to begin life, for that, in a sense, is a congenital defect, and arterial tissue that is poor in quality is prone to disease. the author is more and more impressed with the part that heredity plays in the determination of arterial degeneration. especially does syphilis in the parents or grandparents leave its stigma in the succeeding generations in the shape of poor arterial tissue which is prone to early degeneration. recently w. w. graves has called attention to a malformation of the vertebral border of the scapula which consists in a concavity instead of the normal convexity of the bone. to this malformation he has given the name, scaphoid scapula. he considers this to be but one manifestation of a general lack of development in the individual. he speaks of this maldevelopment as a blight and considers that syphilis in the ancestors is responsible for the condition in the offspring. he finds that even in children, the subjects of the scaphoid scapula, the arteries are very definitely thickened. while confirmation of his observations is lacking, there is no doubt that we must lay the blame for much of the arteriosclerosis in our patients to the poor quality of arterial tissue transmitted by ancestors who have acquired some constitutional disease. it may have been syphilis, it may have been the degeneration produced by alcohol or other drug. we can not ignore the part which heredity plays. the various factors to be considered in the production of the acquired form of arteriosclerosis appear to me to be but contributory factors to a very great extent, the essential and fundamental factor being the quality of arterial tissue with which the individual is endowed. arteriosclerosis may occur in infants. cases have been reported of calcification of the arteries in infants and children. the arteriosclerosis may occur without nephritis or rise of blood pressure. cerebral hemorrhage in a child of two years has been seen. heredity in these cases plays a most important rã´le. in many of the reported cases there was no question of congenital syphilis. aneurysms, single or multiple, have been found in the arteries of children, and even the pulmonary artery may show sclerotic changes. =acquired form= as a rule the cases usually seen belong in this group because it seems as if a connection could be established almost always between one or more of the etiologic factors to be described and the disease. while this apparently is the case, we must never lose sight of the part which the quality of the tissue plays. when we leave this out of our calculations we undoubtedly make many false deductions. when two men of the same age who have been exposed to the same conditions as far as we can learn, are found to have quite different arteries, the one normal, the other thickened, we must postulate congenitally poor tissue on the part of the latter. such tissue readily becomes diseased following conditions which would very likely have produced no noticeable effect on perfectly normal, healthy tissue. =hypertension= hypertension must still be reckoned with in the etiology of arteriosclerosis although the rã´le that it was thought to play does not seem so important. changes of blood pressure alone are not considered by many to be sufficient for the production of arteriosclerosis. this may play some part, but there are many other factors mostly unknown which determine in any case the production of arterial lesions. with every systole of the heart, blood is forced out into the arterial system against a certain amount of resistance represented by the tonicity of the capillary area, and the amount of cohesion between the viscous blood and the walls of arterioles. when a dilatation of the capillaries over any large area takes place, the blood pressure falls, provided there is no compensatory contraction in other areas to make up for the decreased resistance in the dilated vessels. the viscosity of the blood, as such, probably has very little effect on the resistance to the flow. with the systole of the heart there is a sudden dilatation of the arch of the aorta, and a wave of expansion follows, which is transmitted to the periphery and is lost only in the capillaries. the blood pressure is constantly changing. physiologically there are relatively wide variations in the pressure in a perfectly normal individual. there are some persons who have hypotension, a blood pressure much below the normal. such persons have usually small hearts, small aortas, and they seem to have but little resistance to disease. many diseases, especially the prolonged fevers, diminish markedly the blood pressure. whether the hypertension is the cause of the structural changes that are found in the walls of the vessels, or is the result of the diminished area of the arterial tree through which the same amount of blood has to be driven as before the vessel walls became narrowed, is still disputed. as has been stated, experimental evidence would tend to place the initial blame upon the poisons circulating in the blood, which first damage the vessel walls. the subsequent changes then produce thickening and inelasticity. some think (allbutt) that the hypertension is primary. there are cases seen clinically that lend support to this view and there is experimental evidence also (v. chap. ii). not infrequently individuals in middle life begin to show increase of arterial blood pressure without discoverable cause. in such case it may be that there is slowly progressing chronic nephritis. the urine if examined only superficially in single specimens may not reveal any abnormalities. careful functional examination by means of the newer tests may reveal functional deficiency. it must not be supposed that all cases of increasing hypertension are cases of chronic nephritis. the opinion has already been expressed (chap. iii) concerning this point. experience has convinced me that the opinion expressed in former editions is not altogether correct. =age= no age is exempt from the lesions of arteriosclerosis if we consider the two groups. however, the disease is seen for the most part in persons past middle life. the relative frequency with which it is found in the different decades depends on so many factors that it is of no value to tabulate them. as has been stated, arteriosclerosis of all types is an involution process that advances with age. longevity is a question of the integrity of the arterial tissue, and no one can tell what sort of "vital rubber" (osler) any one of us has. however, many with poor tubing may make such use of it that it will outlast good tubing that is badly treated. unfortunately we have no way of telling early enough with just what sort of arterial tissue we are starting life. =sex= there is no doubt that men are far more prone to arterial disease than women are; all statistics are in accord on this point. this is explained by the greater exposure of men to those conditions of life which tend to produce circulatory strain, and so to produce arteriosclerosis, or vice versa. arteriosclerosis in women is not often seen until after the fiftieth year. cases of the most extreme grade of pipe stem arteries are, however, seen in old women, and calcified arteries are not hard to find among the inmates of an old woman's home. =race= some of the most beautiful examples of arteriosclerosis in this country are seen in the negro. not only is this disease more frequent in the black race, but the age of onset is much earlier than in the caucasian. the accidents of arteriosclerosis, viz., aneurysm, cerebral hemorrhage, etc., are more common among the negro males. the etiologic factors that are most often found in the history are the prevalence of syphilis and hard physical labor. =occupation= certain occupations have a distinct causal relationship to arteriosclerosis; among such are particularly those entailing prolonged muscular exercise, especially if much lifting is necessary. every one is familiar with the phenomena accompanying the exertion of lifting. the breath is drawn in, the glottis is closed, and the muscles of the chest wall are held rigidly while the exertion lasts. this causes a great increase in blood pressure, and constant repetition of this will produce permanent high tension. in hospitals, the stevedores as a class have marked arteriosclerosis, and, almost without exception, they are comparatively young men. occupations that are accompanied with prolonged mental strain, such as now occur to the heads of large manufacturing and financial institutions, also predispose to early arterial changes. psychic activity, especially when it is accompanied by worry, is a potent factor in the production of the increased blood pressure which is the chief factor in producing arterial disease. it has been suggested that sexual continence in high-strung men produces changes in the nervous system which can conceivably lead to the production of high tension and further to arteriosclerosis. this, however, i can not think has any foundation in fact except in so far as such men are prone to live at high speed and wear themselves out sooner than the normal person. the sexual continence _per se_ is not harmful. there are, however, men who seem not to be harmed by the constant wear and tear of our modern life. these are the exceptions. workers in factories where paint is made and the ingredients hand-mixed, are prone to develop arteriosclerosis early in life. it has been found that the laborers most apt to be victims of lead intoxication are those who are careless in their habits of cleanliness, particularly in regard to the fingernails. the continuous absorption of lead into the system, brings about a condition of hypertension that has its inevitable results. the fact is that any occupation which entails either the absorption of toxic substances, or prolonged muscular labor, will hasten markedly the onset of arterial disease. =food poisons= the opinion that arteriosclerosis is due in large part to poisoning by end products or by-products of protein digestion is now receiving much support. experiments on dogs and rabbits have lent some confirmation to chemical observations. it has been shown that dogs fed for a long time on putrefied meat developed inflammation and degeneration of the adventitia and media, with hyperplasia and calcification of the intima of many arteries. in the pulmonary and carotid arteries, in the vena cavas and myocardium, there were extensive necroses and hyaline degeneration. moreover, injections of sodium urate and ergot caused necroses in the muscularis and elastica of the aorta, pulmonary artery, vena cavas inferior and heart muscle, but there was no calcification. guinea pigs which were fed indol in small doses by the mouth over a long period showed atheromatous degeneration of the aorta. =infectious diseases= as more study has been given to the arteries in persons who have died of the acute infectious diseases, more has come to light concerning the effects of the toxins of these diseases on the vessel walls. in the arteries of children who have died of measles, scarlet fever, diphtheria, cerebrospinal meningitis, etc., degenerative changes in the arteries occur, modified only by the length of time that the toxins have acted. thayer has shown that the arteries of those who have passed through an attack of moderately severe or severe typhoid fever are as a rule more readily palpable than are the vessels of persons of corresponding years who have never had the disease. clinically the typhoid toxin appears to cause the early production of arteriosclerosis. the changes in the arteries occur for the most part, and always earlier, in the peripheral arteries, and the media is chiefly affected. minute yellowish patches are found on the aorta, carotids, and coronaries. in persons who have passed through an attack of one of the fevers, and have later died from some other cause, regenerative changes are sometimes found to have taken place in the arteries, consisting of an ingrowth of elastic fibers from the intact adventitia to the diseased media. that there are some other factors than the infectious disease which are concerned in the production of arterial changes seems evident from a study[14] made recently among a group of almshouse inmates ranging in age from 38 to 90 years. the study included 500 persons of both sexes. careful histories were taken to determine the presence of antecedent infectious disease. the radial artery was palpated to determine the presence of sclerosis. among the cases giving a history of one infectious disease the following table gives the results: ------------------------------------------------------------ disease no. + ++ +++ positive negative ------------------------------------------------------------ measles 47 10 6 12 28 19 infectious arthritis 38 9 6 4 19 19 pneumonia 30 5 8 5 18 12 typhoid 27 6 8 3 17 10 scarlet fever 10 0 0 4 4 6 smallpox 14 1 4 0 5 9 miscellaneous 12 2 5 2 9 3 ------------------------------------------------------------ 178 33 37 30 100 78 ------------------------------------------------------------ [14] warfield, l. m.: jour. lab. and clin. med., november, 1917. a summary of the cases showed: 252 cases without sclerosis; 248 with sclerosis; 147 cases with infections but no sclerosis; 180 cases with infections and sclerosis. this study failed to throw any positive light on the question. infectious diseases undoubtedly play a certain rã´le, particularly those continuing a long time and certain particular infectious diseases, as measles. =syphilis= syphilis is one of the most important of the etiologic factors in the production of arteriosclerosis. it has been shown that in 85 per cent of cases of aortic insufficiency in persons, usually males, over forty-five years, who did not have chronic infective endocarditis, the wassermann reaction was positive. acute aortitis affecting the ascending and transverse portions of the arch of the aorta is very commonly seen, and the irregular, scattered, slightly raised, yellowish-white patches of sclerosis in the arch which are found years after the syphilitic lesion, are considered by some to be very characteristic of syphilis. mesaortitis is the primary lesion and acts as a _locus minoris resistentiã¦_ where an aneurysm forms. hypertensive cardiovascular cases have been serologically studied, and a positive wassermann reaction found in a large percentage of one series. in fifty cases, 90 per cent either gave a positive wassermann reaction or luetin test, were known to have syphilis, or had children with hereditary syphilis. this suggests what might be called "familial cardiovascular syphilis." hypertensive disease is possibly one of the common so-called "late" manifestations of syphilis. that syphilis is responsible for the arterial disease in the vessels of the brain, resulting in apoplexy or sudden cardiac death in middle life, has long been known. in fact, it is claimed (osler) that all aneurysms occurring in persons under thirty years of age are due to syphilitic aortitis. in the late stages of syphilis the arterial lesions may be of a diffuse character. =chronic drug intoxications= lead, tobacco, and according to some, tea and coffee, are to be classed as causal factors in the production of arteriosclerosis. certain it is that all these substances have a tendency to raise the arterial pressure, but whether the drug itself causes first a degeneration, and later a hypertension results, or vice versa, is not yet positively known. we have just mentioned that lead particularly has a marked effect in producing arterial lesions. other drugs as adrenalin, barium chloride, physostigmin, etc., while producing experimental arteriosclerosis, hardly could produce the disease in man. =alcohol= has been blamed for much, and as an etiologic factor in the production of arteriosclerosis formerly was accorded a first place. more recently much doubt has been thrown on this supposition by the work of cabot, who showed that the mere drinking of even large quantities of spirits had no effect in producing arterial disease. this observation has been recently substantiated by hultgen, who carefully studied clinically 460 cases of chronic alcoholism. he says, "there are no cardiovascular symptoms which might be termed characteristic of chronic alcoholism, unless it be the peculiar fetal qualities of the heart sounds which we know as embryocardia. i find this very frequent among drinkers, but i can offer only a tentative explanation for it, namely the following: embryocardia can only occur with low tension blood pressure, and in the absence of renal insufficiency. hence it might be considered as a useful condition of no pathologic significance at all. that alcohol is a sclerogenic pharmakon and productive of arteriosclerosis with its usual train of symptoms may be a fact, but its demonstration would be difficult and is really not shown by my tabulations. there were cardiovascular changes, such as myocarditis, aortitis, valvular heart disease and arteriosclerosis in chronic alcoholics in 54.3 per cent of 461 cases, but this by no means constitutes a proof of the causal relationship between these lesions and the abuse of liquors. i believe it, nevertheless, to be good reasoning to ascribe the bulk of cardiovascular symptoms to the sclerogenic action of alcohol, while abstaining from an interpretation of its pathogenesis." just what rã´le =tobacco= plays is difficult to say. my own opinion is, that of itself when used in moderation, it has no ill effects. however, as tobacco is a drug that may raise the blood pressure, excessive use must be held responsible for the production of arteriosclerosis. it is difficult to separate its effects from those produced by eating and drinking. =overeating= there can be no doubt but that the constant overloading of the stomach with rich or difficultly digestible food is responsible for a large number of cases of arteriosclerosis. every one must have noted the increase in force and volume of the heart beat after the ingestion of a large meal. the constant repetition of such processes conceivably can lead to damage to the vessel walls through hypertension. in the metabolism of food in the intestines there are substances produced which are poisonous when absorbed directly into the circulation. ordinarily these substances are rendered harmless either before absorption or are detoxicated in the liver to harmless substances. it is conceivable that a constant overproduction of such poisons would eventually damage the defensive mechanism of the body to such an extent that some of the poisons would circulate in the blood. an expression of a surplus of one, at least, of these decomposition products is the appearance of indican in the urine. it is not believed that indicanuria has the importance attached to it which some authors would have us believe. it is found too often and in too many varying conditions, nevertheless it undoubtedly does reveal the presence of perverted metabolism. in how far the toxins absorbed from the intestinal tract are responsible for the production of arterial disease, it is not possible to say. some observers lay great stress on this factor as a cause of arteriosclerosis. the author believes that the rã´le played by the absorption of products of perverted intestinal metabolism is an important one. the primary change is an increased tension in the arterioles which later leads to thickening of the coats of the vessels and to the other consequences of arterial disease. a vicious circle is thus established which has a tendency to become progressively worse. =mental strain= more and more does one become impressed with the fact that patients with arteriosclerosis are very often those who take life too seriously and either from ambition or from an exalted sense of duty lead especially strenuous lives. not always are these persons addicted to drug or liquor habit. many are rather abstemious in their habits. it is not so often that we see as a victim of arteriosclerosis, the carefree person who laughs his way through life without worrying about the morrow. he is not so prone to arteriosclerosis. worry is a far more potent cause of breakdown than actual manual work. it is the rule to find thickened arteries among neurasthenics. this may be only part of a generalized degeneration of all tissue in the body. the blood pressure in such persons is usually low. so many men of our better class live under a continuous mental strain in the business world. the increase in arteriosclerosis cases is real, not apparent. the intense mental strain seems to cause a marked increase in blood pressure (for short periods of mental effort this has been proved) over a period of time sufficient to cause permanent changes in the vessel walls. the same sequence of events repeats itself; high tension, arterial strain, compensatory thickening, hypertrophied heart, etc. certainly the character of the arterial tissue has much to do with the determination of degenerative changes which may result from the action of one or more of the etiologic factors. =muscular overwork= muscular overwork is to be reckoned with as an etiologic factor. one sees it especially among the laboring class in both whites and negroes. possibly other factors, as alcohol and coarse heavy food, contribute to the early arterial degeneration. hypertrophy of the heart occurs in athletes, and statistics gathered among the oarsmen especially, show a relatively high mortality at the different decades traceable to the high tension produced while in training. this question deserves more consideration than has been accorded it. =renal disease= chronic disease of the kidneys (contracted red kidney) is one of the most certain producers of hypertension; in fact, some maintain that high tension, even without demonstrable kidney lesions, as revealed by careful urine examinations, is a valuable sign pointing to chronic nephritis. this is doubted by others, myself among them. just what causes the increase in blood pressure sometimes to over 270 mm. of hg, is not definitely known. it seems most probable that it is some poison elaborated by the diseased kidneys and absorbed into the general circulation. there it acts primarily on the musculature of the arterioles causing tonic contraction and an increase of work on the part of the heart to force the blood through narrowed channels. one fact is certain. we see patients in coma due to renal disease with blood pressure much over 200 mm of hg. as these cases clear up, the pressure may fall, and should they seemingly recover, the recovery is accompanied with a marked decrease in blood pressure, finally reaching the normal for the individual. moreover, in the course of a severe acute or subacute nephritis, hypertension is associated with headache, partial or total blindness, and drowsiness. when the pressure is reduced, all these symptoms disappear. there is also the chronically shrunken and scarred kidney known pathologically as the arteriosclerotic kidney. it is probable that there are two groups of cases which we may designate: (1) primary; (2) secondary. in the primary group the kidney disease antedates the sclerosis of the arteries, and the sclerosis is most probably dependent on the constant high tension. we know that prolonged hypertension will produce severe forms of arteriosclerosis. the arterial disease in this group is caused by the renal disease. in the second group the kidney changes are apparently due to the general arteriosclerosis which, affecting the kidney vessels, causes changes leading to atrophy and subsequent fibrous tissue ingrowth of scattered areas. these cases are not necessarily associated with hypertension; on the contrary there is more apt to be hypotension. where the first group occurs for the most part in young and active middle-aged people, the second group is the result of involutionary processes which accompany advanced age. however careful a urinalysis may be, there is no assurance that one can predict the pathologic state of the kidney. often so-called normal urine will be secreted by a badly diseased kidney, whereas a urine which contains considerable albumin and many casts may be secreted by a kidney which is only temporarily the seat of inflammation. what matters after all is not the state of the kidney which the pathologist describes, but the actual functional response of the kidney in the body to the various tests now well known. =ductless glands= at the present time the tendency among some writers is to make the ductless glands the responsible agents in almost all diseases. arteriosclerosis is no exception to this tendency. sajous, for example, divides the morbid process producing arteriosclerosis into three types; (1) autolytic, (2) adrenal, (3) denutrition. in the first type he finds the pancreas to be the most important gland. it supplies an internal secretion which "takes a direct part in the protein metabolism of the tissue cells, and also in the defensive reactions within these cells, as well as in the phagocytes and in the blood stream." this being the case exaggeration of this digestive process has tissue destruction as its result, arteriosclerosis among them. in the adrenal type sajous argues that adrenalin produces lesions experimentally, therefore the adrenal gland has a profound influence by its internal secretion in connection with the sympathetic system in producing degenerations leading to arteriosclerosis. the denutrition type has as its particular gland the thyroid. the sclerotic process in the arteries is due to the lack of thyroid as in cases of myxedema. after a long rã©sumã© of his ideas he concludes "that arteriosclerosis is the result of excessive or deficient activity of certain ductless glands, the thyroid and adrenal in particular." no one can dogmatically deny the part which the ductless glands may play in the production of arteriosclerosis, but it hardly seems that there is enough actual experimental evidence to show that they take such an important part as sajous believes. until further and more convincing evidence is offered by competent investigators, i prefer to look with some skepticism upon the ductless gland theory of the causation of arteriosclerosis. the field lends itself too easily to speculation and imagery. some are already allowing themselves the mental debauch of this nature. chapter vii the physical examination of the heart and arteries =heart boundaries= in order to be able to estimate the departures from normal in the boundaries of the heart, it is essential that there be a definite appreciation of the boundaries of the normal heart in relation to the chest wall. it is frequently stated that the right limit of cardiac dullness is normally, in the adult, just at the right border of the sternum. this is not strictly accurate. careful dissections at the autopsy table and x-ray plates of the chest made at a distance of two meters from the tube show that the border of the right auricle is from one to one and a half and even two centimeters from the edge of the sternum at the level of the fourth rib, and on the living subject this can be also demonstrated. the right border of the heart usually is from 3 to 4 cm. from the midsternal line at the level of the fourth rib. again there is a term used in defining the apex, known as the point of maximum impulse. as this does not always coincide with the apex beat and with the outer lower left border of the heart, it would be better to use the term apex beat. normally, then, the cardiac dullness, the so-called relative cardiac dullness, begins above at the upper border of the third costal cartilage, as a rule, and taking a somewhat curved line with the concavity inward, descends to the fifth interspace or beneath the fifth rib from 9 to 10 cm. from a line drawn through the center of the sternum parallel to its length, the midsternal line. this seems to me to be a better method of recording the size of the heart than by the lines commonly used; viz., the nipple, or midclavicular, or parasternal line. below, the cardiac dullness is merged into the tympany from the stomach and the dullness from the liver. at the sixth right costosternal articulation there is a sharp turn upwards forming at that point with the liver the cardiohepatic angle. at the fourth right cartilage or the third interspace, the dullness is from one to two centimeters from the edge of the sternum. we have then a somewhat pear-shaped area or triangular area with the apex at the apex of the heart. the so-called absolute cardiac dullness does not appear to me to be of any great significance. in reality it is the limit of lung resonance and may be greater or less, not so much on account of variations in the size of the heart, as of variations in size of the lungs and shape of the chest wall. the really crucial question which should always be asked is, is the heart enlarged or decreased in size? the position of the apex beat alone can not determine this, neither can the limit to the right of the sternum. the distance between these two points and the depth of the dullness at a distance of 5 cm. from the midsternal line on the left side, will give the size of the heart as nearly as can be obtained in the living subject. a series of measurements in normal adults average 13 to 14 cm. and 9 to 10 cm. respectively. for women they are about 1 cm. less in each direction. the elaborate mechanism known as the orthodiagraph is probably the best means of determining the actual limits of the heart, but few men have such an expensive instrument, and, moreover, at the bedside such an instrument could not be used. from comparative measurements i concur in the belief of those who affirm that careful percussion will furnish equally as accurate limits. the first step in making an examination of the heart is to expose the patient's chest in a good light, and, sitting at his right side, carefully inspect the chest. the position of the apex beat, heaving, bulging, retraction of interspaces, etc., can easily be seen if visible. after careful inspection has given all the data which it is possible to obtain, one next lays the palm of the hand over the heart and attempts to palpate the apex beat. the thrust of the apex in a hypertrophied heart can readily be felt, and one can feel whether the heart is regular, irregular, intermittent, or has other change in rhythm. the shock of the closing valves, particularly the aortic, can be felt, and that and the forcible apical impulse are very suggestive signs of hypertrophy and hypertension. thrills may also be felt and can be timed in relation to the heart cycle. =percussion= it is to percussion that we next proceed, and for the data in regard to the size of the heart, it is, for our purpose, the most valuable of all the physical methods of heart examination. first and foremost we wish by percussion to learn the actual size of the heart, in other words what is ordinarily called the relative cardiac dullness. with the absolute dullness we are not concerned. that irregular area represents, as has been said, actually the =limits of lung resonance=. the heart may or may not be covered with lung; there may or may not be the incisura cardiaca. what i wish to insist upon is that the size of the area of absolute dullness can give us no data in regard to the size of the heart. what we must endeavor to learn is the actual size of the heart as nearly as our crude means will permit. light, very light, almost inaudible percussion, what goldscheider called "schwellungsperkussion," must be practiced. use the middle finger of the right (left) hand as the hammer and the last joint of the middle finger of the left (right) hand pressed firmly against the chest, as pleximeter. i believe it is better to place the pleximeter finger parallel to the boundary to be limited although some place the finger perpendicularly, that is, pointing toward the boundary. now and then it helps to bend the pleximeter finger at the second joint, hold it perpendicularly to the chest wall, and strike the joint directly in line of the finger. this in my hands has been of great assistance in percussing the limits of the heart dullness. pottenger's "light touch palpation" is a modification of the light palpation and, to my mind, has no very special advantages. auscultatory percussion is of great value at times. the bell of the stethoscope is placed over the portion of heart uncovered by lung (should such be the case), and with this point as a center the chest is lightly and quickly tapped along radii converging toward the stethoscope. one soon learns to recognize the change of pitch as the tapping reaches the border of the heart. it is well to use all methods, especially in difficult cases, and to compare the results. personally i have found that by light percussion i can limit with much accuracy the upper, right, and left borders of the heart. there is much to be gained by using light percussion. strong blows set in vibration not only the underlying structures, but also more or less of the chest wall. we wish to avoid this source of error, we do not wish to differentiate by pitch alone. finally one's pleximeter finger becomes, after long practice, so sensitive to changes in the resonance of structures lying below it, that there is actual feeling of impairment to the slightest degree. this delicate touch is what we should endeavor to cultivate. it is at times of advantage to use immediate percussion. this is done by bending the fingers of the striking hand, bringing the tips in a line and striking the chest lightly with the four fingers as one finger. some find it easier to percuss the dullness due to the heart in this way than by mediate percussion. the little hammer and hard rubber, celluloid, bone, or ivory pleximeter does not seem to me to be nearly as good as the fingers. moreover, one always has his hands, but may forget his hammer and pleximeter. =auscultation= in auscultating the heart i prefer the binaural stethoscope of the ford pattern. the recent substitution of an aluminum bell for the hard rubber bell is an improvement. personally i do not favor the phonendoscope or any of the new patent non-roaring instruments now for sale by urgent instrument makers. the phonendoscope has its uses, for example in auscultating the back when a patient is lying in bed or in listening to the heart sounds when a patient is under an anesthetic; but for differentiating the murmurs and for heart diagnosis, i much prefer the regular bell stethoscope. in arteriosclerosis the two places over which it is important to listen are the apex and the second right cartilage, the aortic area. over the former, one gains data in regard to the strength of the heart as indicated by the first sound, over the latter point, one learns of the tension in the aorta by the character of the sound produced when the aortic valves close. the hypertrophy of the heart in arteriosclerosis is invariably due to the enlargement and thickening of the left ventricle. from the nature of the position which the heart assumes in the thorax, this enlargement is downward and to the left. the apex beat will therefore be found in the fifth or sixth interspace, and definitely at an increased distance from the midsternal line. as stated above, it is most important that this distance be accurately measured and put down in the notes of the case for future reference. no satisfactory prognosis can be given unless this is done, for the gradual increase or the decrease under treatment in the size of the heart can thus be definitely known, and, knowing the other factors, a prognosis may be given which will be of some value to the patient. =the examination of the arteries= it is exceedingly difficult at times to affirm definitely that an artery, the radial for example, is actually sclerosed. much depends on the sensitiveness of the fingers of him who palpates, and much upon the relation of the palpated artery to the surrounding, chiefly underlying, structures. in the examination of arteries it is well to inspect the body for the pulsations caused by them. frequently an exceedingly tortuous artery, such as the brachial, may be seen throughout its whole extent and yet the radial appear little, if any, thickened by palpation. again the artery of a pulse of high tension which is small in size but full between the beats, may not be as sclerosed as one which collapses and feels much softer. it is difficult to obtain accurate data in regard to the tension in an artery by feeling it with the fingers of one hand. one should use both hands. with the middle finger of the right (left) hand the artery is compressed peripherally, that is, nearest the wrist. the blood is then pressed out of the artery with the middle finger of the left (right) hand, so as to obliterate completely the pulse wave and the two or three inches between the middle fingers are felt with the index fingers. by holding the finger firmly on the artery near the wrist so as to block any wave that may come through the palmar arch by anastomosis with the ulnar artery and by releasing pressure on the proximal middle finger, some idea may be had of the degree of pulse tension. however, no amount of practice can more than approximate the tension and when one is surest that he can tell how many millimeters of pressure there are, he is apt to be farthest wrong when he checks his guess with the sphygmomanometer. much may be learned from carefully palpating the peripheral arteries, and, as a rule, the sclerosis of these arteries means general arteriosclerosis, although there are many exceptions to this. a more recent method, and one which in the author's hands has been found to be valuable, is that proposed by wertheim-salomonson who palpates the artery not with the ball of the finger but with the fingernail. the finger is held so that the nail is perpendicular to the surface of the skin and the artery is felt with the end of the nail. the sensation is perceived at the root and makes use of all the sensitive nerve endings there. in this way it is possible to feel the arterial wall distinctly, and a little practice will enable one to determine whether or not the vessel wall is thickened. it is also possible to determine with a considerable degree of accuracy the diameter of the artery and the size of the wall when the current is cut off by pressure on the proximal side of the artery. it is best to have a firm background when this "fingernail" palpation is used. this may be obtained by palpating the radial artery against the lower end of the radius. probably the best method of palpating the arteries, especially the radial, to determine the degree of sclerosis and thickening, is to use the tip of the finger and roll it carefully over the artery. the tip of the finger is exceedingly sensitive and, moreover, it is a firmer palpating surface than the ball, thus enabling one to appreciate degrees of sclerosis which could not be differentiated by palpation with the soft yielding ball. this finger tip palpation is well illustrated in the figures here shown. (figs. 57 and 58.) [illustration: fig. 57.--a method of finger-tip palpation of the radial artery. (graves.)] [illustration: fig. 58.--another method of finger-tip palpation of the radial artery. (graves.)] =estimation of blood pressure= it must be borne in mind at the outset that arteriosclerosis and high blood pressure are not always associated. as a matter of fact in the severest grades of senile arteriosclerosis the blood pressure is usually below the normal for the individual's years. however, as high tension is a frequent factor in the production of arterial thickening, blood pressure readings are of importance. the instrument which one uses is of minor importance provided it is properly standardized. the most important feature of the instrument is the cuff. this must be 12 cm. wide and be long enough to wrap around the arm several times so that the pressure is evenly distributed over the whole arm and not over a small portion. one mercury instrument we had in the hospital was reported to be at great variance with a dial instrument. this mercury instrument was provided with a cuff which was short and was tied around the arm by means of a piece of tape. this caused a tight constriction over a small area and rendered the estimation too high. a new, long tailed cuff easily remedied the apparent defect in the instrument. in taking blood pressures the difference from day to day of 10 or even 15 mm. of systolic pressure has no great significance. fluctuations of the systolic pressure alone, it is insisted upon, have very little meaning. one must take the whole pressure picture into consideration and determine how the picture changes in order to draw any conclusion in regard to the state of the blood pressure. failure to pay attention to this evident point has caused much futile work to be written and published. it is well to emphasize again the point that the blood pressure picture consists of the systolic, the diastolic, the pulse pressure and the pulse rate. =palpation= hoover has called attention to the direct palpation of the femoral artery just below poupart's ligament as a more accurate index of the pressure in the aorta than the palpation of the radial artery. possibly one can obtain a more accurate estimate of the blood pressure in this way. this, however, is open to dispute. to estimate the blood pressure by palpating the radial artery is most deceptive. in about 75 per cent of cases one can tell fairly well whether the pressure is abnormally high or abnormally low. small variations are impossible to determine. unquestionably it is most advantageous to get into the habit of palpating the femoral artery and checking the result with the sphygmomanometer so that the fingers may be trained to appreciate as accurately as possible changes of pressure. it may be that one day when the instrument is needed it is not at hand. a well-trained touch then becomes a great asset. =precautions when estimating blood pressure= there are certain precautions which must be strictly observed when deductions are drawn from the manometer readings. the psychic factor must be reckoned with. any emotion may cause marked variations in the pressure. excitement and anger are especial sources of error. even the slight excitement arising from taking the first blood pressure on a nervous patient especially is apt to give false values. usually the readings must be taken many times at the first sitting and the first few may have to be set aside. worry is a potent factor in raising the pressure. a walk to the physician's office, especially if rapid, has its effect. the position of the patient when the blood pressure is taken is important. usually in the office the pressure is taken when the patient sits in a chair. he should assume a relaxed, comfortable attitude. the readings should be made at the same time of day and at the same interval between meals. the pressure in both arms should be measured and comparisons should be made only between readings on the same arm. these precautions may seem useless and even somewhat trivial, and the conditions difficult to control. but unless they are carefully observed the readings will be false, no comparisons can be drawn between the readings on different days, and the instrument will most probably be blamed. i have known this to happen so often that i can not emphasize too strongly the importance of controlling all the essential conditions which go to make accurate work. =the value of blood pressure= in the past few years there has been a veritable avalanche of blood pressure instrument salesmen who have covered the country, sold instruments, and have made many startling claims for the instrument. they have emphasized its value out of proportion to what the instrument can do even in the hands of one familiar will all the defects. consequently it is not necessary to emphasize the value of blood pressure. it seems best to utter a few words of caution in regard to its interpretation. the value lies not in the occasional estimation compared with some other one reading, but in the frequent estimation and in the visualization of the blood pressure picture. for the great majority of diseases the blood pressure has no particular value except to show that the circulation is not materially disturbed. the limits of normal are rather wide, so that consideration of the patient's age, sex, build, etc., will give us some idea of a base line, so to speak, for any one person. wide departures from relatively normal figures are important, but are not diagnostic or, rather, pathognomonic. i can not help but feel that the diastolic pressure is _the_ most important part of the blood pressure picture. persistent high diastolic pressure means increased work for the heart, which, if acting for a long time against the high peripheral resistance, must eventually hypertrophy. the arteries become thickened, lose their wonderful elasticity, fibrous tissue is deposited in their walls, and the vicious circle is established which leads to pathologic hypertension. blood pressure readings must be intimately mixed with brains in order to be of any great value in diagnosis or prognosis. chapter viii symptoms and physical signs =general= well developed arteriosclerosis shows four pathognomonic signs: (1) hypertrophy of the heart; (2) accentuation of the aortic second sound; (3) palpable thickening of the arteries; and (4) heightened blood pressure. however, it must not be inferred that these signs must be present in order to diagnose arteriosclerosis. it has already been said that a very marked degree of thickening, with even calcification of the palpable arteries, may occur with absolutely no increase of blood pressure, and at autopsy a small flabby heart may be found. while arteriosclerosis is usually a disease which is of slow maturation, nevertheless cases are occasionally seen which develop rather rapidly. the peripheral arteries have been noticed to become stiff and hard in as relatively brief a time as two years from the recognized onset of the disease. since involution processes are physiologic, as has been described (vide infra), arteriosclerosis may assume an advanced grade and run its course devoid of symptoms referable to diseased arteries. it is doubtful whether the sclerosis itself could produce symptoms, except in cases later to be described, were it not that the organs supplied by the diseased arteries suffer from an insufficient blood supply and the symptoms then become a part of the symptom-complex of any or all the affected organs. there are cases, however, in comparatively young persons where a combination of certain ill-defined symptoms gives a clue to the underlying pathologic processes. these symptoms of early arteriosclerosis are the result of slight and variable disturbances in the circulation of the various organs. normally there are frequent changes in the blood pressure in the organs, but the vasomotor control of normal elastic vessels is so perfect that no symptoms are noted by the individual. when the arteries are sclerosed, they are less elastic and the blood supply is, therefore, less easily regulated. at times symptoms occur only after effort. the patient may tire more readily than he should for a given amount of mental or bodily exercise; he is weary and depressed, and occasionally there is noted an unusual intolerance of alcohol or tobacco. vertigo is common, especially on rising in the morning or in suddenly changing from a sitting to a standing position. some complain of constant roaring or ringing in the ears. there may be dull headache that the accurate fitting of glasses does not alleviate. unusual irritability or somnolency with a disinclination to commence a new task may be present. sometimes the effort of concentrating the attention is sufficient to increase the headache. this has been called "the sign of the painful thought." numbness and tingling in the hands, feet, arms, or legs are also complained of, and neuralgias, not following the course of the nerves but of the arteries, also occur. it is important to remember that the train of symptoms resembling neurasthenia in a person over forty-five years old may be due to incipient arteriosclerosis. this tardy neurasthenia frequently accompanies cancer, tuberculosis, diabetes, and incipient general paralysis, as well as incipient arteriosclerosis. bleeding from the nose, epistaxis, taking place frequently in a middle-aged person, sometimes is an early symptom. the bleeding may be profuse, but is rarely so large as to be positively harmful. in fact, it may do much good in relieving tension. slight edema of the ankles and legs is seen. dyspnea on slight exertion is not uncommon. dyspeptic symptoms are not infrequent, pyrosis (heartburn), a feeling of fullness after meals with belching or a feeling of weight in the epigastrium. the dyspeptic symptoms may be so marked that one might almost speak of a variety of arteriosclerosis, the dyspeptic type. for quite a while before any symptoms that would definitely fix the case as one of undoubted arteriosclerosis, the patient complains that foods which previously were digested with no difficulty now give him gastric distress. the examination of the stomach contents of a patient presenting gastric symptoms reveals usually a subacidity. the total acidity measured after the ewald test meal may be only 20 and the free hcl may be absent. attention has been called to an unnatural pallor of the face in early arteriosclerosis. progressive emaciation is sometimes seen in cases of arteriosclerosis and may be the only symptom of which the patient complains. =hypertension= not all cases of arteriosclerosis are accompanied by increased arterial tension. as has been stated in a previous chapter, the blood pressure in the arterial system depends chiefly on two factors; viz., the degree of peripheral (capillary) resistance, and the force of the ventricular contraction. the highest arterial pressures recorded with the sphygmomanometer occur not in pure arteriosclerosis but in cases where there is concomitant chronic interstitial disease of the kidneys. when this is found there is always arteriosclerosis more or less marked. in cases where the arteries are so sclerosed that they feel like pipe stems there may be an actual decrease in the blood pressure. hence the clinical measuring of the pressure in the brachial artery alone is not sufficient for a diagnosis of arteriosclerosis. a persistent high blood pressure even with normal urinary findings is not a sign of arteriosclerosis. the high tension later may lead to the production of sclerosis of the arteries, but in these cases the kidney may be primarily at fault. the impression must not be gained that hypertension in itself always constitutes a disease or even a symptom of disease. hypertension itself is practically always a compensatory process. that is to say, it is the attempt on the part of the body to equalize the distribution of blood in the body when there is some poison causing constriction of the small arteries. in this sense hypertension is not only essential, but actually life-saving. a heart which is so diseased that it can not respond to the call for increased action by hypertrophy of its fibers, would shortly wear out. the very fact that the heart becomes enlarged and the tension in the arteries becomes high, indicates that in such a heart there was great reserve power. but while hypertension is largely an effort at adjustment among the various parts of the circulation, it nevertheless tends to increase, provided the cause or causes which produced it act continuously. moreover, as has been said (chap. ii), the arterioles do not respond to increased work on the part of the heart by expanding, but by contracting. a vicious circle is thus maintained which eventually must lead to serious consequences. hypertension is then, if anything, only a symptom which may or may not demand treatment. that hypertension leads to the production of sclerosis of the arteries has been repeatedly affirmed here. in certain cases it is good and should not be experimented with. in other cases it is bad and some treatment to reduce the tension must be tried. the main point is to regard hypertension as one regards a compensated heart lesion. prof. t. clifford allbutt divides the causes of arteriosclerosis clinically into three classes: (1) the toxic class--the results of poisons of the most part of extrinsic origin, chiefly those of certain infections. in some of these diseases, the blood pressures, as for example, in syphilis, are ordinarily unaffected; in others, as in lead poisoning, they are raised. (2) the class he calls hyperpietic,[15] in which an arteriosclerosis is the consequence of tensile strength, of excessive arterial blood pressure persisting for some years. a considerable example of this class is the arteriosclerosis of granular kidney, but in many cases kidney disease is, clinically speaking, absent. (3) the involutionary class, in which the change depends upon a senile, or quasisenile degradation. this may be no more than wear and tear, a disposition of all or of certain tissues to premature failure--partly atrophic, partly mechanical--under ordinary stresses; or it also may be toxic, a slow poisoning by the "faltering rheums of age." in ordinary cases of this class the blood pressures for the age of the patient are not excessive. although the toxins of the specific fevers, notably typhoid, as stated above, and influenza, have been shown to produce arteriosclerosis, this, under favorable circumstances he believes tends to disappear. this has been shown by wiesel. [15] from piesã´ to squeeze, oppress or distress. hyperpiesis, therefore, signifies excessive pressure. as the blood pressure is dependent on the resistance offered by the capillaries and arterioles, there are only two ways in which increased pressure can be brought about; either by rendering the blood more viscous, or by the generation of some poison from the food taken into the body which, acting on the vasomotor center or directly on the finer vessels, arteriolar or capillary, sets up a constriction over any large area, and mainly in the splanchnic area. in regard to the liability to arteriosclerosis, this area stands second only to the aortic and coronary areas. he believes that arteriosclerosis itself has little effect in raising arterial pressure. many cases are seen in which with extreme arteriosclerosis there was no rise in blood pressure, and some in which pressures have been rising even long before the appearance of arterial disease. prof. allbutt also believes that in the hyperpietic cases the arteries undergo a transient thickening, which can be removed if the causes can be reached and overcome. clinically speaking, then, hyperpietic arteriosclerosis is not a disease, but a mechanical result of disease. if the narrowing of the arterioles is brought about by thickening due to arteriosclerosis, then it would seem _a priori_ that such obliteration should cause a rise in pressure. were the vascular system a mere mechanical set of tubes and a pump, this would happen, but other factors of great importance must be taken into consideration besides the mechanical factors; viz., chemical and biological factors. thus, whole parts may be closed and with compensatory dilatation in other parts there would be little or no change in pressure, unless there were hyperpiesis. in established hyperpiesis, we note two conditions in the radial artery: first, a comparatively straight vessel with a small diameter; secondly, a larger, more tortuous vessel, "the large leathery artery." in the cases of the first group, hyperpiesis is often more marked, although not appearing so to the examining finger, than in the second class. in view of the difficulty of estimating by touch alone the amount of hyperpiesis in a contracted hard artery, it is often overlooked until a ruptured vessel in the brain startles us to a realization of our mistake. the "narrow" artery is more dangerous than the tortuous one, for with every change in pressure the passive vessels of the brain must receive blood that under normal conditions would go to other parts of the circulation. in involutionary sclerosis there is a gradual thickening and tortuosity of the vessel, which although it may be greater than in the hyperpietic cases, yet is never so dangerous to life. the heart in hyperpiesis hypertrophies and dilates, but such a heart is the result, not an integral part, of the arterial disease. =the heart= when the arterial tree becomes narrowed and the resistance offered to the flow of blood thereby is increased, more muscular work is required of the left ventricle and according to the general laws which govern muscles the ventricle hypertrophies. there is an actual increase in number of fibers as well as an increase in the size of the individual fibers. some of the best examples of simple hypertrophy of the left ventricle are found under such circumstances. the chambers as a rule do not dilate until the resistance becomes greater than the contraction can overcome, when symptoms of broken compensation of the heart take place. the hypertrophy of the left ventricle brings more of this portion of the heart toward the anterior chest wall. the enlargement is toward the left, also, consequently the apex-beat is found below and to the left of its usual site, even an inch or more beyond the nipple line. the impulse is heaving, pushing the palpating hand forcibly up from the chest wall. the visible area of pulsation may occupy three interspaces and the precordium is seen to heave with every systole. on auscultation the second sound at the aortic cartilage is ringing, clear, and accentuated. not infrequently, too, the first sound is loud and booming, but has a curious muffled sound that may even be of a murmurish quality. the leaflets of the mitral valve may be the seat of sclerosis, the edges are slightly thickened and do not quite approximate, thus causing a definite murmur with every systole. this murmur may be transmitted out into the axilla and be heard at the inferior angle of the left scapula. =palpable arteries= not every artery that can be felt is the subject of arteriosclerosis, and, as has been stated, palpable arteries being more or less a condition of advancing years, judgment as to whether the artery is pathologically or physiologically thickened may be a matter of individual opinion. a radial artery that lies close to the lower end of the radius and can actually be seen to pulsate when the hand is held slightly extended on the back of the wrist, is easily felt, but must not, therefore, be considered a sclerosed artery. the radial may be so deeply situated in the wrist of a fat subject that it is difficultly palpable. yet the two cases just described may have arteries of identical structure, there being no more retrogressive changes in the one than in the other. "experience is fallacious and judgment difficult." the small, contracted, wiry artery of a chronic nephritic may feel like a pipe stem, but if properly felt the mistake will not be made of considering such an artery an unusually sclerosed one. when the wave is pressed out of such a high tension artery, it is found that what seemed to be a firm sclerosed vessel, was in reality an artery tightly stretched over the column of blood. =ocular signs and symptoms= it would not exaggerate too much to say that the examination of the eye grounds with the ophthalmoscope is the most important aid in the early diagnosis of arteriosclerosis. long before there are any subjective symptoms, changes can be seen in the blood vessels of the retina which, while not always diagnostic, at least call attention to a beginning chronic disease. as i become more proficient in the use of the ophthalmoscope, i am impressed with the importance of the ocular signs of arterial disease. i would urge practitioners to familiarize themselves with this instrument. the electrically lighted instruments on the market now have so simplified the technic that any physician should be able to see the grosser changes which take place in the arteries and veins of the retina and in the disc. frequently the ophthalmologist is the first to recognize early arteriosclerosis. in the fundus are seen increased tortuosity of the retinal vessels and their terminal twigs with more or less bending of the vessels at their crossings. the arteries are terminal ones, and small patches of retinitis are therefore found. the changes have been divided into (1) suggestive, (2) pathognomonic. under (1) are: (a) uneven caliber of the vessels, (b) undue tortuosity, (c) increased distinctness of the central light streak, (d) an unusually light color of the breadth of the artery. under (2) are: (a) changes in size and breadth of the retinal arteries so that they look beaded, (b) distinct loss of translucency, (c) alternate contractions and dilatations in the veins, (d) most important of all, the indentation of the veins by the stiffened arteries. there is yet another sign which appears to be pathognomonic. the arteries are pale, appear rigid and through the center, parallel to the course, is a rather bright, fine threadlike line. the appearance is known as the "silverwire" artery. it is particularly constant in hypertension where the most beautiful examples are seen. moreover, there is the arcus senilis, the fine translucent to opaque circle surrounding the outer portion of the iris. practically every one with a well-marked arcus senilis has arteriosclerosis, but vice versa not every one with even marked arteriosclerosis has an arcus senilis. in general, the symptoms are gradual loss of acute vision, and attacks of transient loss of vision. the explanation which has been offered for these phenomena is the contraction in a diseased central artery. =nervous symptoms= the onset of arteriosclerosis is, in the majority of cases, so insidious that certain nervous manifestations, due in all probability to disturbances in blood pressure, are present long before the actual sclerosis of the arteries can be felt. these nervous symptoms are at times the sign posts to show us the way to accurate diagnosis. there may be gradual increase in irritability of temper, inability to sleep, vertigo even extending to transient attacks of unconsciousness. loss of memory for details frequently is an early symptom of sclerosis of the cerebral arteries. nervous indigestion may be present. various paresthesias as numbness, tingling, a sense of coldness or of heat or burning, a sense of stiffness or even actual stiffness or weakness may occur in the arms and legs, more frequently in the legs. the pain complained of may be due to occlusion of an artery, although evidence for this is lacking. it has been thought by some that the pain in angina pectoris might be due to this cause. several curious and interesting diseases which have been thought by some to have arteriosclerosis as a basis are accompanied by pain. such are erythromelalgia, raynaud's disease, "dead fingers," and intermittent claudication. erb has reported a large series of intermittent limp (claudication) from his private practice. he finds that the large majority of the cases occur in men. the abuse of tobacco was evidently the main etiologic factor in about half of the cases. repeated exposure to cold and the abuse of alcohol were responsible for most of the other cases. curiously enough he finds that a history of syphilis was present in only a small proportion of his cases. it is his firm conviction that intermittent limping--which he thinks should be called angiosclerotic dysbasia--is frequently incorrectly diagnosed. it is mistaken for other troubles and treated wrongly. as gangrene may develop this is particularly dangerous. the affection generally develops gradually, although he has seen cases where the onset was rather acute. the partial or complete lack of the pulse in the foot is the one striking sign, together with the varying behavior of the pulse, its disappearance when the feet are cold and its return after a warm foot bath or under other treatment. signs of general arteriosclerosis were present in nearly every case. when there is a tendency to the development of intermittent limp he finds that a valuable sign is the manner in which the leg blanches when it is lifted repeatedly while the patient is recumbent and becomes hyperemic later when placed horizontally. in health this change occurs more rapidly. chapter ix symptoms and physical signs =special= our conception of arteriosclerosis as a degenerative process affecting the vascular tree rather than a disease, removes the possibility of discussing special symptoms. as a matter of fact, we know of very few organs where even profound pathologic changes in the vascular system produced during life any symptoms which could be laid to these arterial changes. kind nature has given to us such an excess of organs of every kind that the destruction of large portions of any organ seems to affect the function but little. so only particular groups of organs, which show symptomatic changes as the result of arteriosclerotic processes, will be discussed. it is realized that this may not give teutonic completeness to the discussion, but it certainly saves paper and has a distinct practical value to the long suffering reader. although arteriosclerosis is a disease which affects the whole arterial system, it nevertheless never reaches the same grade all over the body. the difference in the structure and functions of the various organs determines to great extent the eventual symptomatology. endarteritis obliterans of a small sized artery in the liver or leg would lead to no marked symptoms, as the circulation is so rich that the anastomoses of the blood vessels would soon establish a collateral circulation that would be perfectly competent to sustain the function of the part. quite different would it be should one of the small arteries of the brain, the lenticulo-striate, for example, which supplies the corpus striatum, become the seat of a thrombosis or embolism caused by arteriosclerosis. the arteries of the brain are terminal arteries and the blood supply would be cut off entirely with a resulting anemic necrosis of the part supplied by the artery and a loss of function of the part. what would be of no moment in the leg or arm might prove even fatal in the brain. the further symptomatology, therefore, of arteriosclerosis depends entirely on the organ or organs most affected by the interference with the blood supply. the following groups may be recognized: 1. cardiac. 2. renal. 3. abdominal. 4. cerebral. 5. spinal. 6. local vasomotor effects. 7. pulmonary. =cardiac= most cases of arteriosclerosis sooner or later present symptoms referable to the heart. when the organ is hypertrophied and is already working against an enormous peripheral resistance, a slight excess of work put upon it may cause a dilatation of the chambers with the resulting broken compensation. there is dyspnea on slight exertion, possibly some precordial distress, slight edema of the ankles and lower legs and possibly scanty urine. with proper care, a patient with such symptoms may recover, but the danger of another break in compensation is enhanced. the next attack is more severe. the edema is greater, there may be signs of edema of the lungs, effusions into the serous cavities may occur. the heart shows marked dilatation. there is gallop or canter rhythm and there are loud murmurs at the apex. when a patient is first seen in this stage, it may be quite impossible to state whether or not there is true valvular disease of the heart. the muscle is usually diseased in that there is fibroid degeneration of more or less extensive character. this factor causes the heart to lose much of its elasticity and increases the tendency to permanent dilatation. such cases must be watched before one can say that true valvular insufficiency is not present. the fatal termination of such a case is quite like that of true valvular disease. there is increasing dyspnea, increasing anasarca, and the patient usually succumbs to edema of the lungs, drowned in his own secretions. [illustration: fig. 59.--aneurysm of the heart wall. (milwaukee county hospital.)] a very rare complication of the fibroid degeneration of the heart muscle is aneurysm of the heart wall. (fig. 59.) the apex of the left ventricle is most commonly the site of the aneurysm and rupture occasionally occurs. such an accident is rapidly fatal. in the arteriosclerotic process which occurs at the root of the aorta, the coronary arteries become involved both at the openings and along the courses of the vessels. a branch or branches or even one artery may become blocked as a result of obliterating endarteritis. the arteries of the heart are not terminal vessels but as a rule blocking of a large branch leads to anemic infarct. these areas become replaced by fibrous tissue which in the gross specimen appears as streaks of whitish or yellowish color in the musculature. anemic infarcts may not occur. in such cases the anastomosis between branches of the coronary arteries is unusually free. through arteriosclerosis of the coronary vessels extensive fibrous changes may occur that lead to a myocardial insufficiency with its attending symptoms--dyspnea, irregular and intermittent heart, gallop rhythm, edema, etc. one of the most distressing and dangerous results of sclerosis of the coronary arteries and of the root of the aorta is angina pectoris. while in almost every case of angina pectoris there is disease of the coronary arteries, the contrary does not hold true, for most extensive disease, even embolism, of the arteries is frequently found in persons who never suffered any attacks of pain. this symptom group is more common in males than in females and as a rule occurs only in adult life. "in men under thirty-five syphilitic aortitis is an important factor." (osler.) since the valuable experiments of erlanger on heart block, considerable attention has been paid to lesions of the y-shaped bundle of fibers, a bundle arising at the auriculoventricular node and extending to the two ventricles, known also as the auriculoventricular bundle of his. interference with the transmission of impulses through this bundle gives rise to the symptom group known as the stokes-adams syndrome, which is characterized by: (a) slow pulse, (b) cerebral attacks--vertigo, syncope, transient apoplectiform and epileptiform seizures, (c) visible auricular impulses in the veins of the neck. many of the cases which occur are in elderly people the subjects of arteriosclerosis. [illustration: fig. 60.--large aneurysm of the aorta eroding the sternum. death from rupture through the skin preceded by frequent small hemorrhages. (milwaukee county hospital.)] so far as we now know all cases of the stokes-adams syndrome are caused by heart block which is only another name for disease in the auriculoventricular bundle. of interest here is the fact that besides gummata, ulcers, and other lesions of the bundle, definite arteriosclerotic changes have been found. "the investigation of a typical case of stokes-adams disease has shown that the symptoms of this case are caused by some lesion in the heart which gives rise to the condition now generally termed heart block. practically all degrees of heart block have been observed, namely, complete heart block and partial block with 4:1, 3:1, and 2:1 rhythm, and occasionally ventricular silences. these stages occurred during recovery. "experiments testing the reaction of the heart to various extrinsic influences demonstrate that when the block is complete the ventricles do not respond to influences presumably of vagus origin, although the auricles still respond normally to such influences, that effects exerted upon the heart presumably through the accelerators still influence the rate of the ventricles as well as that of the auricles. "when the block is partial the rate of the ventricular contraction varies proportionally with the rate of the auricular contractions but only within certain limits. when these limits are exceeded the block becomes more complete, i. e., a 2:1 rhythm may be changed into a 3:1 rhythm, this into a 4:1 rhythm, and this into complete block, and vice versa. "the syncopal attacks are, in all probability, directly dependent upon a marked reduction of the ventricular rate. such reductions of the ventricular rate are always associated with an increase of the auricular rate, and it is believed that the latter is the cause of the former." (erlanger.) the epileptiform seizures of the syndrome may be caused by the anemia of the brain resulting from failure of the heart to supply a sufficient quantity of blood. the apoplectiform attacks are most probably caused by venous congestion when the slowing of the ventricular contractions is not sufficient to cause convulsions, but will just cause complete unconsciousness. =renal= chronic nephritis, hypertension, arteriosclerosis form a most important trinity. some stoutly affirm that in all cases of high tension there is chronic renal disease. certainly the very highest blood pressures which we see occur in the chronic interstitial forms of kidney disease. the cause is most probably to be sought in some poison which is elaborated in the kidney, is absorbed into the circulation and acts powerfully either on the vasoconstrictor center as a stimulus, or directly on the musculature of the small arteries all over the body. usually hypertension is progressive but it may be temporary. a man, 43 years old, entered the milwaukee county hospital in uremic coma. the systolic blood pressure was 280-290 mm. hg, the diastolic pressure 220 mm. (janeway instrument). under treatment his blood pressure gradually became lower, at the same period the albumin and casts gradually disappeared from the urine. in two weeks from admission he seemed perfectly well, there were no albumin or casts found in the urine, and the systolic blood pressure was 136 mm., not a high figure for a muscular man of the laboring class. it must be admitted, however, that such cases are the exception, not the rule. patients suffering from the association of chronic nephritis with hypertension die slowly, usually. there is gradual development of anasarca. headache is frequent and severe. pains all over the body may occur. the sight may suddenly become dim or may even be lost. dizziness may be complained of and dyspnea is usually marked. cyanosis comes on, the pulse becomes weak, irregular or intermittent, heart failure sets in, and the patient dies with edema of the lungs. another class of renal arteriosclerosis is characterized by a small granular kidney in which fibrous changes of a patchy character have taken place. these scattered areas are the result of obliterating endarteritis of renal arteries here and there with consequent anemia, death of cells, and replacement by fibrous tissue. it occurs as part of a generalized arteriosclerosis in which the whole arterial system is the seat of diffuse (senile) sclerosis. the palpable arteries are usually beaded or even encircled with calcareous deposits and the aorta is the seat of an extensive nodular and ulcerating sclerosis. the heart is usually small, shows extensive fibrous and fatty changes and possibly the condition known as "brown atrophy;" the blood pressure is low. such cases do not show any special symptoms. they are anemic, short of breath on exertion, have the appearance and show the signs of senility. in the first group it is, at times, difficult to say whether the kidney disease or the arterial disease is the most important. from a clinical standpoint the decision is not essential as the end results are much the same in both. however, when actual uremic symptoms dominate the picture, it becomes evident that the disease of the kidney is the chief feature in the causation of the symptoms. =abdominal or visceral= there is an important group of cases to which but little attention has been paid until quite recently. this is the abdominal or visceral type of arteriosclerosis. it has been stated that arteriosclerosis of the splanchnic vessels almost invariably causes high tension. among others, janeway has shown that general arteriosclerosis without marked disease of the splanchnic vessels does not cause as a rule increase of blood pressure. there are cases in which the brunt of the lesion falls upon the abdominal vessels. such cases have been called "angina abdominalis." it has been suggested (harlow brooks) that this type of arteriosclerosis may be determined by constant overloading of the stomach with food, especially rich and spiced food. this causes overwork of the special arteries connected with digestion and so leads to sclerosis of the vessels of the stomach, pancreas, and intestines. personal habits probably influence to great extent the production of this more or less =localized= condition. the organs supplied by the diseased arteries suffer from changes analogous to those occurring in general or local malnutrition, such as starvation, old age, or local anemias. these changes are atrophy with hemachromatosis (brown atrophy) or fatty infiltration and degeneration. following the degenerative changes there result connective tissue growth and further limitation of the functionating power of the affected organs. pain is a more or less constant symptom of visceral sclerosis. in the early stages there may be only a sense of oppression, of weight, or of actual pressure in the abdomen or pit of the stomach. there may be only recurring attacks of violent abdominal pain accompanied by vomiting. in some cases symptoms of tenderness in the epigastrium, pains in the stomach after eating, vomiting and backache may suggest gastric ulcer. there may be dyspnea and a sense of anguish accompanied with a rapid and feeble pulse. hematemesis may make the symptom group even more like ulcer of the stomach, and only the course of the disease with the failure of rigid ulcer treatment and the substitution of treatment directed toward relief of the arterial spasm with resulting betterment, enables one to make a diagnosis. the condition may be present for years and the symptoms only epigastric tenderness with dizziness and sweating on lying down after dinner, as in one of perutz's patients. the attacks are probably due to spasmodic contraction of the sclerosed intestinal vessels with a resulting local rise in blood pressure. the pains are most probably due to the spasm of the intestinal muscles, and some think they are located in the sympathetic and mesenteric plexuses. this result of arteriosclerosis is not so uncommon, and by keeping this cause of obscure abdominal pain in mind we are now and then enabled to save a patient from operation. an autopsy on a case which for many years had attacks of abdominal pain and cramp-like attacks, with high blood pressure and heart hypertrophy, showed extensive sclerosis of the abdominal aorta, superior mesenteric and iliacs. these vessels were calcified. hypertrophy of the left ventricle was found. the kidneys were microscopically normal. there were no changes in the ascending aorta but in the descending portion there were scattered nodules and small calcified plaques. the attacks of pain from which this patient suffered for many years, the hypertrophy of the left ventricle and the increased blood pressure were thought to be directly due to the sclerosis of the abdominal vessels. =cerebral= it has been stated that arteriosclerosis is a general disease, yet certain systems of vessels may be affected far more than others, and indeed there may be marked sclerosis at one part of the body and none demonstrable at another part. in advanced sclerosis there may be one or more of a series of accidents due to embolism, thrombosis, or rupture of the vessels. such conditions as transient hemiplegia, monoplegia or aphasia may occur. the attacks may come on suddenly and be over in a few minutes; what allbutt calls "larval apoplexies." they may last from a few hours up to a day, and are very characteristic. a patient aged 64 years with pipe stem radials and tortuous hard temporals would be lying quietly in bed when suddenly he would stiffen, the eyes would become fixed and the breathing cease. in a few seconds consciousness returned, the patient would shake himself, pass his hand over his brow and ask, "where am i? oh, yes, that's all right." he had as many as thirty of these attacks in twenty-four hours, none of them lasting over one minute. to just what such attacks are due, it is hard to say. some have attributed them to spasm of the smaller blood vessels of the brain, but there have never been demonstrated in the vessels any constrictor fibers. there is a well recognized form of dementia caused by arteriosclerosis. in general paralysis of the insane and in senile dementia the blood vessels are always diseased. milder grades of psychic disturbances are accompanied by such symptoms as mental fatigue, persistent headaches, vertigo, memory weakness and fainting. aphasia, periods of excitement and mental confusion occur in some. later stages are at times accompanied by inclination to fabulate, loss of judgment, disorientation, narrowing of the external interests, episodes of confusion and hallucinatory delirium. the hemiplegias, monoplegias and paraplegias may occur again and again and last for one or two days. unless there has been rupture of the vessels, there is complete recovery as a rule. in persons who have arteriosclerosis with high tension attacks of melancholia are seen. there are at the same time fits of depression, insomnia, irritability, fretfulness, and a generally marked change in disposition. when the tension is reduced by appropriate treatment these symptoms disappear, to recur when the tension again becomes high. on the contrary, attacks of mania are accompanied by low blood pressure. the dizziness and vertigo in cerebral arteriosclerosis are probably due to the stiffness of the vessels which prevents them from following closely the variations of pressure produced by position, and thus, at times, the brain is deprived of blood and a transient anemia occurs. arteriosclerosis of the cerebral vessels is always a serious condition. the greatest danger is from rupture of a blood vessel. another of the dangers is gradual occlusion of the arteries bringing about necrosis with softening of the brain substance. the latter is more apt to be associated with psychic changes, dementia, etc.; the former, with hemiplegia. it is curious that a small branch of the sylvian artery, the lenticulo-striate, which supplies the corpus striatum, should be the one which most frequently ruptures. where the motor fibers from the whole cortex are gathered together in one compact bundle, a very small hemorrhage may and does cause very serious effects. a comparatively large hemorrhage in the silent area of the brain may cause few or no symptoms. =spinal= it is conceivable that arteriosclerosis of the vessels of the spinal cord might cause symptoms which would be referred to the areas of the cord where the process was most advanced. the lesions would be scattered and consequently the symptoms might be protean in character. true epileptic convulsions dependent on arteriosclerotic changes are also seen and are not so uncommon. this is on the whole a rare condition, much less common than arteriosclerosis of the cerebral vessels. collins and zabriskie report the following typical case: "h., a fireman, fifty-one years old, was in ordinary good health until toward the end of 1902. at that time he noticed that his legs were growing weak and that they tired easily. later he complained of a jerking sensation in different parts of the lower extremities and at times of sharp pain, which might last from several minutes to two or three hours. the legs were the seat of a heavy, unwieldy sensation, but there was no numbness or other paresthesia. about the same time he began to have difficulty in holding the urine, a symptom which steadily increased in severity. these symptoms continued until march, 1903, i. e., for three months, then he awakened one morning to find that he was unable to stand or walk, and the sphincters of the bowels and bladder relaxed. there was no complaint of pain in the back or legs, no difficulty in moving the arms, in swallowing or in speaking. he says he was able to tell when his lower extremities were touched and he could feel the bed and clothes. he was admitted to the city hospital three weeks later and the following record was made on april 21, 1903. "the patient was a frail, emaciated man of medium height, who had the appearance of being 55-60 years of age. he was unable to stand or walk. when he was lying, he could flex the thigh and the legs slowly and feebly. there was slight atrophy of the anterior and inner muscles, more of the left than of the right side. the knee jerks and ankle jerks were absent. irritation of the soles caused quite a typical babinski phenomenon. the patient had fair strength in the upper extremities, but the arms tired very soon, he said. the grip was moderate and alike in each hand. the motility of the face, head, and neck was not noticeably impaired. there was no difficulty in swallowing, and articulation was not defective. tactile sensibility was slightly disordered in the lower extremities, although he could feel contact of the finger, the point of a pin, and the like. sensibility was not so acute as normal; there was a quantitative diminution. sensory perception was not delayed. there was a distinct zone of slight hyperesthesia about as wide as the hand above the femoral trochanters. above that, sensibility was normal. there was no discernible impairment of thermal sensibility. no part of the body was particularly tender on pressure. a bedsore existed over the sacrum, and there was excoriation of the genitals from constant dribbling of urine. "examination of the chest showed shallow respiratory movements. the heart was regular, weak, there were no murmurs, the second sound was accentuated. examination of the abdomen showed that the liver and spleen were palpable, but were not enlarged. the abdominal reflexes, both upper and lower, were sluggish. the patient was slow of speech, likewise apparently of thought. he did not seem to show an adequate interest in his condition, still he was fully oriented and seemed to have a fair memory. his mental reflex was slow. there were indications in the peripheral blood vessels and heart of a moderate degree of general arteriosclerosis. the peripheral vessels such as the radial, were palpable, the walls thickened, the blood pressure increased. "the patient did not complain of pain while he was in the hospital, a period of four weeks, nor was there any particular change in the patient's symptoms, subjective and objective, during this time. his mental state remained clear until forty-eight hours before death, when he became sleepy, stuporous, and comatose, dying apparently of cardiac weakness, which had set in simultaneously with the clouding of consciousness." at autopsy, except for a few small hemorrhages in the posterior horns of the lower dorsal segments on the right side and a similar condition of the left anterior horns, there was nothing noticed. on microscopic examination, there was found widespread sclerosis of the vessels of the cord to a marked degree with only slight thickening of the vessels of the brain. there were secondary degenerations of ascending and descending type particularly marked at the ninth dorsal segment. they included portions of all the tracts, the pyramidal tract as well. the symptoms in brief were: (1) weakness and easily induced fatigue of the legs; (2) peculiar sensations in the lower extremities, described as jerky, numbness, heaviness, and occasionally sharp pain; (3) progressive incontinence of urine; (4) progressive paraplegia. since one of the chief manifestations of syphilis is sclerosis of the arteries, neurologic cases characterized by irregular symptoms and signs which can not be placed in any of the definite system disease groups, are possibly due to irregularly scattered areas of sclerosis throughout the spinal cord caused by obliterating arteritis. such cases are not so very uncommon. several have come under my observation. further studies of the spinal cords of these cases at autopsy are necessary before a final opinion can be given as to their dependence on arteriosclerosis of the spinal vessels. =local or peripheral= when the arteriosclerosis in the peripheral arteries reaches a stage where endarteritis obliterans supervenes, there is usually no chance for a compensatory or collateral circulation to be established. the area supplied by the vessel undergoes dry gangrene. a portion of a toe or finger or a whole foot or hand may shrivel up. it is more common to see the spontaneous amputation take place in the lower extremities. the same effect may be produced by the plugging of a vessel with a thrombus. there may be much pain connected with the sudden blocking, whereas the gradual obliteration of the blood supply of a toe or foot is not as a rule at all painful. the condition is at times revealed more or less accidentally when a patient injures his toe or foot and discovers that there is no sensation in the part and that the wound instead of healing is inclined to grow larger. other interesting vasomotor phenomena are frequently connected with arteriosclerosis. such a one is the curious condition known as raynaud's disease, a vascular disorder which is divided into three grades of intensity: (1) local syncope, (2) local asphyxia, (3) local or symmetrical gangrene. this is not the place to describe this condition except to say that the condition called "dead fingers" is the most characteristic feature of the first stage. chilblains represent the mildest grade of the second stage. the parts are intensely congested and there may be excruciating pain. any one who has ever had chilblains knows how painful they can be. the general health is not impaired as a rule, although the attacks are apt to come on when the person is run down. the third stage may vary from a very mild grade, with only small necrotic areas at the tips of the fingers, to extensive multiple gangrene. another and very rare condition in which chronic endarteritis was the only constant finding is the disease described by s. weir mitchell and called by him erythromelalgia (red neuralgia). this is "a chronic disease in which a part or parts--usually one or more extremities--suffer with pain, flushing, and local fever, made far worse if the parts hang down." (weir mitchell.) probably the most frequently seen result of arteriosclerosis in the leg arteries is the remarkable condition, first described by charcot, known as intermittent claudication. persons the subject of this disease are able to walk if they go slowly. if, however, any attempt be made to hurry the step, there results total disability accompanied at times by considerable cramp-like pain. the condition is much more prone to occur in men than in women, and hebrews seem more frequently affected. the cause is most probably to be sought in the anemia which results from the narrowing of the channels through which the blood reaches the part. the stiff, much narrowed arteries allow sufficient blood to pass along for the nutrition of the part at rest or in quiet motion. just as soon as more violent exercise is taken, calling for more blood, an ischemia of the part supervenes, for the stiff vessels can not accommodate themselves to changes in the necessary vascularity of the part. a rest brings about a gradual return of blood and the function of the part is restored. pulsation may be totally absent in the dorsal arteries of the feet and when the legs are allowed to hang down there is apt to be deep congestion. in this connection a curious case reported by parkes weber will not be out of place. the patient, a male, aged 42 years, complained of cramp-like pains in the sole of the left foot and calf of the leg occurring after walking for a few minutes and obliging him to rest frequently. when the legs were allowed to hang over the side of the bed, the distal portion of the left foot became red and congested looking. no pulsation could be felt in the dorsal artery of the left foot or in the posterior tibial artery. there was no evidence of cardiovascular or other disease. an ulcer on the little toe had slowly healed, but cramp-like muscular pains still occurred on walking. the disease had lasted about five years without the appearance of gangrene. weber calls this case one of arteritis obliterans with intermittent claudication. =pulmonary artery= in the symptomatology of sclerosis of the pulmonary artery the clinical signs and symptoms are mostly referable to the obliterating endarteritis of the smaller vessels, while the physical signs are more apt to reveal the involvement of the main trunk. a history of severe infection in the past is frequent, especially smallpox, and accompanying aortic sclerosis with insufficiency of the mitral valve or stenosis of this valve is the rule. striking cyanosis is an early symptom, while there is little if any dyspnea and edema. intermittent dyspragia is common. there seems to be no tendency to clubbed fingers. repeated hemorrhages from the lungs without the formation of infarcts may occur. there is usually an area of dullness at the upper left margin of the sternum and nearby parts, sensitive to pressure and to percussion, and the heart dullness extends unusually far towards the right. the diagnosis of the right ventricular hypertrophy may be substantiated by a fluoroscopic examination. chapter x diagnosis =early diagnosis= arteriosclerosis is essentially a disease of middle life and old age. it is not unusual, however, to find evidences of the disease in persons in the third decade and even in the second decade. hereditary influences play a most important rã´le, syphilis and the abuse of alcohol in the family history are particularly momentous. the recognition of the early changes in the arteries among young persons depends largely upon how carefully these changes are looked for. the difference in the point of view of one man who finds many cases in the comparatively young, and another man who rarely finds such changes early in life, at times, depends upon the acuity of perception and observation and not upon the fact that one man has had a series of unusually young arteriosclerotic subjects. the diagnosis of arteriosclerosis may be so easily made that the tyro could not fail to make it. it is, however, the purpose of this volume to lay stress on the earliest possible diagnosis and, if possible, to point out how the diagnosis may be arrived at. it is obviously much to the advantage of the patient to know that certain changes are beginning in his arteries, which, if allowed to go on, will inevitably lead to one or more of the symptom groups described in the preceding chapters. the combination of (1) hypertrophied heart, (2) increased blood pressure, (3) palpable arteries, and (4) ringing, accentuated second sound at the aortic cartilage is, in reality, the picture of advanced arteriosclerosis. if the individual is in good condition much may be done by judicious advice and treatment to ward off complications and prolong life with a considerable degree of comfort. but we should not wait until such signs are found before making a diagnosis and instituting treatment. as in all forms of chronic disease the early diagnosis is all important. the history of the case is the first essential. often a careful inquiry into the personal habits of a patient, with the record of all the preceding infectious diseases will give us valuable information and may be the means of directing the attention at once to the possible true condition. particularly must we inquire into the family history of gout and rheumatism. an individual who comes of gouty stock is certainly more prone to arterial degeneration than one who can show a healthy heredity. alcoholism in the family also is of importance because of the fact that the children of alcoholics start in life with a poor quality of tissue, and conditions that would not affect a man from healthy stock might cause early degeneration of arterial tissue in one of bad ancestry. what infectious diseases has the patient had? even the exanthemata may cause degenerations in the arteries, but, as has been shown, such lesions probably heal completely with no resulting damage to the vessel. should the patient have passed through a long siege of typhoid fever the problem is quite different. here (vide supra) (thayer), the palpable arteries do appear to be sclerosed permanently. probably the length of time that the toxin has had a chance to act determines the permanent damage to the vessel wall. more potent than all other diseases to cause early arteriosclerosis is syphilis, and hence very careful inquiry should be made in regard to the possibility of infection with this virus. not only the fact of actual infection but the duration and thoroughness of treatment are important matters for the physician to know. what is the patient's occupation? has he been an athlete, particularly an oarsman? has he been under any severe, prolonged, mental strain? is he a laborer? if so, in what form of manual labor is he engaged? such questions as these should never be overlooked, as they form the foundation stones of an accurate diagnosis, and early, accurate diagnosis, we repeat, is essential to successful therapy. we have called attention to the factor of sustained high pressure in the production of arteriosclerosis. constant overstretching of the vessels leads to efforts of the body to increase the strength of the part or parts. the material which is used to strengthen the weakened walls has a higher elastic resistance than muscle and elastic tissue, but a lower limit of elasticity, and is none other than the familiar connective tissue. in athletes, laborers, brain workers who are under constant mental strain, and in those whose calling brings them into contact with such poisons as lead, there is every factor necessary for the production of high tension and consequently of arteriosclerosis. another question in regard to personal habits is how much tobacco does the patient use and in what form does he use it? our experience is that the cigar smoker is more prone to present the symptoms of arteriosclerosis than the cigarette smoker, the pipe smoker, or the one who chews the tobacco. a very irritable heart results not infrequently from cigarette smoking but such is almost always found in young men in whom the lesions of arteriosclerosis are exceedingly rare. the probabilities are that the arteriosclerosis in cigar smoking results from the slowly acting poison which causes a rapid heart rate with an increase of pressure. last but not least, and perhaps the most important question is, has the patient been a heavy eater? this i believe to be a potent cause of splanchnic arteriosclerosis with the resulting indigestion, cramp-like attacks, high blood pressure, etc. in a joking manner we are accustomed to remark, "overeating is the curse of the american people." there is, however, much truth in that sentence. osler, than whom there is no keener observer, states that he is more and more impressed with the fact that overloading the stomach with rich or heavy or spiced foods is today one of the first causes of arterial degeneration. it stands to reason that this is true. we know that organs exposed constantly to hard work undergo hypertrophy, and that the blood tension in those organs is high. blood tension is, after all, dependent on capillary resistance, and if the capillaries are distended with blood, the resistance is great. the digestive organs can be no exception to this rule. increased work means an increase of blood. this inevitably causes distension of the capillaries with stretching of the arteries and consequent damage to the walls. once arteriosclerosis is present a vicious circle is established. a man about forty-five consults us and says that he has noticed recently that he gets out of breath easily; in tying his shoes he experiences some dizziness. he finds that he has palpitation of the heart and possibly pain over the precordial region now and then. he notices also that he is irritable, that is, his family tell him he is, and he notices that things that formerly did not annoy him, now are almost hateful to him. on examination, one finds a palpable radial, a somewhat hypertrophied heart and slightly accentuated second aortic sound. the blood pressure may be high. the urine may or may not reveal any abnormalities. not infrequently, although no albumin may be found, there are hyaline casts. such a case of arteriosclerosis is evidently not to be regarded as early. then the question arises, how are we to recognize early arteriosclerosis? i do not believe that the solution of this problem lies entirely in the hands of the physician. some men are fortunate enough to come up for an examination for life insurance before an observant doctor who recognizes the palpable artery, makes out the beginning heart hypertrophy and the slightly accentuated second aortic sound. the patient will tell you that he never felt better in his life. he gets up at seven, works all day, plays golf, drinks his three to six whiskies, and is proud of his physical development. but the great mass of people are not fortunate from this standpoint. they do not seek the advice of the physician until they are stretched out in bed. they boast of the fact that for twenty years they have never had a doctor. one may well say that it is a problem how to reach such persons. it seems to me that there can be but one way to do this. the people must be taught that the duty of a physician is just as much to keep them in health as it is to bring them back to health when they are ill. to that end people should be taught that at least twice a year they should be carefully examined. i do not mean that the patient should present himself to the doctor and, after a few questions the doctor say cheerfully, "you are all right." the patient should be systematically examined. that means a removal of the clothing and examination on the bare skin. such cooperation on the part of patient and doctor would save the patient years of active life and make of the doctor, what his position entitles him to be, the benefactor to the community. too often careless work on the physician's part lulls the patient into a false sense of security and he wakes up too late to find that he has wasted months or years of life. early diagnosis of arteriosclerosis is only possible in exceptional cases unless people present themselves to the physician with the thought in mind that he is the guardian of health as well as the healer. there are patients who go to the ophthalmologist for failing vision. physically they feel quite well. they have been heavy eaters, hard workers, men and women who have been under great mental strain. on examination of the fundus of the eye there is found slight tortuosity of the vessels with possibly areas of degeneration in the retina. a careful physical examination will usually reveal the signs of arteriosclerosis elsewhere. we have mentioned frequently high tension as an early sign. this must be taken with somewhat of a reservation, for this reason: not infrequently a persistent high tension is the earliest sign of chronic nephritis. the arteries may be pipe stem in character and the heart small and flabby. however, if one watches for the palpably thickened superficial arteries (always bearing in mind the normal palpability as age advances) and the high tension, he can not go far wrong in his treatment whether the case is one of chronic nephritis or of arteriosclerosis. there is also this to bear in mind. arteriosclerosis may be marked in some vessels and so slight in the peripheral vessels that it can not with certainty be made out. but when the radials are sclerosed, it is usually the case that similar changes exist in other parts. then too, there may be marked changes at the root of the aorta leading to sclerosis of the coronary vessels alone, and the first intimation that the patient or any one else has that there is disease, may be an attack of angina pectoris. except for symptoms on the part of the heart there is no way to make the diagnosis of sclerosis of the coronary arteries. =differential diagnosis= in arriving at a diagnosis, when the question is whether or not arteriosclerosis is the main etiologic factor, the most important fact to know is the age of the patient. other points that have been dwelt on fully must of necessity also be borne in mind. possibly the chief conditions that may be confused with some of the results of arteriosclerosis are pseudo angina pectoris which may be mistaken for true angina pectoris, and ulcer of the stomach, appendicitis (?) or other inflammatory abdominal condition which may be mistaken for angina abdominalis. differential tables are sometimes of value in fixing the chief points of difference graphically. =pseudo angina pectoris=. etiology rather certain; hysteria, neurasthenia, toxic agents, and reflex irritations. no age is exempt. usually in young people, chiefly females. paroxysms of pain occur spontaneously, are periodic and often nocturnal. pain, while severe, is diffuse and sensation is of distension of heart. no sense of real anguish. duration may be an hour or more. restlessness and emotional symptoms of causative conditions are prominent. usually no increase in arterial tension. prognosis favorable. =true angina pectoris=. etiology not certain but almost always associated with arteriosclerosis of the coronary arteries and also aortic regurgitation. age is important factor. rare before forty, and males usually affected. paroxysms brought on by overexertions or excessive mental emotion. rarely periodic. intense pain, radiating down arm; heart felt as in a vise. sense of anguish and impending dissolution. duration from few seconds to several minutes. silent and fixed attitude, rigidity rather than restlessness. arterial tension is as a rule increased. prognosis most unfavorable. in differentiating between ulcer of the stomach and angina abdominalis the following points may be of service: =ulcer=. occurs as a rule in young persons, more often females. pain of boring character increased by food and by certain positions with food in stomach. felt through to left of spine. occult blood found in stools. considerable anemia apt to be present. arterial tension usually low. =angina abdominalis=. only occurs in adults over forty who have been heavy eaters and drinkers, mostly males. pain cramp-like, diffuse, although more localized in epigastrium. not necessarily any connection with food. no occult blood in stools. anemia more often absent. arterial tension high. (splanchnic sclerosis.) =diseases in which arteriosclerosis is commonly found= there are certain more or less chronic diseases in which arteriosclerosis is found either as a separate disease or as a result of the chronic disease itself, or the sclerosis may be the cause of the disease. as examples of the first class are diabetes mellitus and cirrhosis of the liver. as examples of the second class are chronic nephritis, gout, syphilis, and lead poisoning. examples of the third class have already been fully described. then certain rare diseases that have been briefly described in this chapter, viz.: raynaud's disease and erythromelalgia are frequently associated with demonstrable arteriosclerosis. chapter xi prognosis in a disease that presents as many vagaries as arteriosclerosis, it is not possible to give a certain prognosis. unfortunately we do not as a rule see the arteriosclerotic until the disease is well advanced, or even after some of the more serious complications have taken place. by that time the condition is progressive, and while the prognosis is grave the individual may live a number of years. it is fortunate for the arteriosclerotic that mild grades of the disease are compatible with a fairly active life. the disease in this stage may become arrested and the patient may live many years. not only in the mild grades is this possible. even patients with advanced sclerosis may enjoy good health provided the organs have not been so damaged as to render them unfit to perform their functions. the frequency with which we see advanced arteriosclerosis at the postmortem table as an accidental discovery, attests the truth of the foregoing statement. yet how often does it happen that individuals, apparently in the best of health, suddenly succumb to an asthmatic or uremic attack, an apoplexy, cessation of the heart beat, or a rupture of the heart due to arteriosclerosis! in order to arrive at an intelligent opinion in regard to prognosis certain factors must be taken into consideration, chief of which are: the seat of the sclerosis; the probable stage; the existing complications; and, last and most important, the patient himself. the whole man must be studied and even then our prognosis must be most guarded. it is much more dangerous for the patient when the process is in the ascending portion of the arch of the aorta than when it has attacked the peripheral arteries. here, at the root of the aorta, are the openings of the coronary arteries and the arteries supplying the brain are close by. the coronary arteries here control the situation. when loud murmurs are heard at the aortic orifice and the heart is evidently diseased, it is useful to divide the endocarditis into two types, the arteriosclerotic and the endocarditic. the etiology of the former is sclerosis and the prognosis is grave because of the liability, nay the probability, that the orifices of the coronary arteries will become narrowed. the etiology of the second type is in most cases rheumatic fever or some other infectious disease, and the prognosis is far better than in the first type. true, the two may be combined. in such a case, the prognosis is entirely dependent upon the course of the arteriosclerosis. the involvement of the arteries in the kidneys is of considerable importance, for it is usually bilateral and widespread. as a rule, the disease makes but slow progress provided that the general condition of the patient is good, but at any time from a slight indiscretion or for no assignable cause, symptoms of renal insufficiency may appear and may rapidly prove fatal. it must not be thought that because the localization of the arteriosclerosis in the peripheral arteries is usually the most favorable condition that it is therefore devoid of ill effects. on the contrary, very serious, even fatal, results may be brought about by interference with the circulation with resultant extensive gangrene of the part supplied by the diseased arteries. the amputation of a portion of a leg, for instance, may relieve, to some extent, an overburdened heart and prove life-saving to the patient, but the neuritic pains are not necessarily relieved. the torture from these pains may be excruciating. no stage of the disease is exempt from its particular danger. in the early stages of the disease before the artery or arteries have had time to become strengthened by proliferation of the connective tissue, there is the danger of aneurysm. later, the very same protective mechanism leads to stiffening and narrowing of the arteries and hence to increased work on the part of the heart with all of its consequences. thrombosis is favored, and where atheromatous ulcers are formed, embolism is to be feared. as the complications and results of arteriosclerosis come to the front every one must be considered by itself and as if it were the true disease. there may be a slight apoplectic attack from which the patient fully recovers, but the prognosis is now of a grave character, as the chances are that another attack may supervene and carry off the subject. yet, after an apoplectic attack, patients have lived for many years. probably the most noted illustration of this is the life of pasteur. he had at forty-six hemiplegia with gradual onset. he recovered with a resulting slight limp, did some of his best work after the stroke, and lived to be seventy-three years old. yet the exception but proves the rule and the prognosis after one apoplectic stroke should always be guarded. the first attack of cardiac asthma is to be looked upon as the beginning of the end. the end may be postponed for some time, but it comes nearer with every subsequent attack. one may recover from what appears to be a fatal attack of cardiac asthma accompanied by edema of the lungs and irregular, intermittent, laboring heart, but the recovery is slow and the chances that the next attack will be the fatal one are increased. the significance of albuminuria is difficult to determine. the kidneys secrete albumin under so many conditions that the mere presence of albumin in the urine may have but little prognostic value. many cases are seen where there is no demonstrable albumin, and yet the patient may suddenly have a cerebral hemorrhage. as a general rule the urine should be carefully examined, but not too much stress should be laid on the discovery of albumin and casts. it is not always possible to determine the extent of the kidney lesion by the urinary examination, yet at any time a uremic attack may appear and prove fatal. after all the most important fact for the patient is not what the pathologist finds in his kidneys after he is dead, but what the living functional capacity of the kidneys is. this can now be determined in a variety of ways as the result of extensive work carried out in quite recent years. the simplest method of determining the functional capacity of the kidneys is by the injection into the muscles of the back of a solution containing 6 mg. of the drug phenolsulphonephthalein in one c.c. of fluid. this comes already prepared in ampules, with full directions for its employment.[16] some clinicians use indigo-carmine in place of phthalein. the general consensus of opinion is in favor of phthalein. [16] i have found the small colorimeter made by hynson, westcott and dunning, baltimore, mo., costing $5.00, a very practical instrument. the nephritic test meal carefully worked out by mosenthal[17] gives much valuable information. the determination of the nonprotein nitrogen or the creatinin in the blood also reveals the functional capacity of the kidneys.[18] [17] mosenthal, h. o.: arch. int. med., 1915, xvi, 733. [18] myers and lough: arch. int. med., 1915, xvi, 536. one might say that the appearance of albumin in the urine of an arteriosclerotic where it had not been before, is a bad sign, and in making a prognosis this must be taken into consideration. bleeding from the nose is not infrequently seen in those who have arteriosclerosis. it can hardly be called a dangerous symptom as it can always be controlled by tampons. there are times when epistaxis is decidedly beneficial as it relieves headache, dizziness, and may avert the danger of a hemorrhage into the brain substance. it is rare to have nose bleed except in cases of high tension in plethoric individuals. my experience has been that it has saved me the trouble of bleeding the patient. it is always of serious import in that it indicates a high degree of tension, but there is scarcely ever any immediate danger from the nose bleed itself. intestinal hemorrhage is always a grave sign. as has been shown, arteriosclerosis of the splanchnic vessels not infrequently occurs, and an embolus or thrombus may completely occlude the superior mesenteric artery. the chances of the establishment of a collateral circulation are small, as the arteries of the intestines are end arteries. necrosis of the part follows, blood is found in the stools, and perforation or gangrene, or both, are apt to follow. there may be blocking of small branches only, leading to ulceration of the intestine. under all conditions the prognosis is serious. the general condition of the patient, his build, physical strength, powers of recuperation, etc., must be taken into account in giving a prognosis. the more powerful the individual, the more favorable, as a rule, is the prognosis, with this reservation always in mind, that the greater the body development, the greater is the heart hypertrophy, and the accidents from high tension must not be overlooked. many puny individuals with stiff, calcified arteries go about with more ease than a robust man with thickened arteries only. the differentiation as pointed out by allbutt (page 186), is well to keep in mind in giving a prognosis. it can not be too strongly emphasized that it is the whole patient that we must consider and not any one system that at the time happens to be the seat of greatest trouble, and by its group of symptoms dominates the picture. it is evident from what has been said that an accurate prognosis in arteriosclerosis is no easy matter. were arteriosclerosis a simple disease of an acute character there might be grounds for giving a more or less definite prognosis. the most that can be said is that arteriosclerosis is always a serious disease from the time that symptoms begin to make themselves known. the gravity depends altogether on the seat of the greatest arterial changes, and is necessarily greater when the seat is in the brain than when it is in the legs or arms. the attitude of the patient himself also determines to a great extent the prognosis. some men, especially those who have always enjoyed good health, turn a deaf ear to warnings and instead of ordering their lives according to the advice of the physician, persist in going their own way in the hope that the luck that has always been with them will continue to stand at their elbows. neither firmness nor pleadings avail with some men. the only salve for the conscience of the physician is that he has done his best to steer the patient away from the shoals and breakers. in others who realize their condition and take advantage of the advice given as to the regulation of their lives, the prognosis is generally favorable. to sum up the chapter in a few words, i should say: always remember that the patient is a human being; study his habits and character and mode of life; look at him as a whole; take everything into consideration, and give always a guarded prognosis. chapter xii prophylaxis arteriosclerosis comes to almost every one who lives out his allotted time of life. as has been noted within, many diseases and many habits of life are conducive to the early appearance of arterial degeneration. decay and degeneration of the tissues are necessary concomitants of advancing years and none of us can escape growing old. from the period of adolescence certain of the tissues are commencing a retrograde metamorphosis, and hand in hand with this goes the deposit of fibrous tissue which later may become calcified. the arterial tissue is no exception to this rule, and we have already shown that certain changes normally take place as the individual grows older, changes which are arteriosclerotic in type and are quite like those caused in younger people by many of the etiologic factors of the disease. we are absolutely dependent upon the integrity of our hearts and blood vessels for the maintenance of activity and span of life. respiration may cease and be carried on artificially for many hours while the heart continues to beat. even the heart has been massaged and the individual has been brought back to life after its pulsations have ceased, but such cases are few in number. we can not live without the heart beat and the prophylaxis of arteriosclerosis consists in the adjustment of our lives to our environment, so that we may get the maximum amount of work accomplished with the minimum amount of wear and tear on the blood vessels. the struggle for existence is keen. competition in every profession or trade is exceedingly acute, so much so that to rise to the head in any branch of human activity requires exceptional powers of mind. among those who are entered in this keen competition, the fittest only can survive for any period of time. the weaklings are bound to succumb. a scion of healthy stock will stand the wear and tear far better than will the progeny of diseased parentage. it is only necessary to call attention to the part that alcohol, syphilis and insanity play in heredity. these have been discussed fully in the earlier part of this book. we live rapidly, burning the candle at both ends. it is not strange that so many comparatively young men and women grow old prematurely. while heredity is a factor as far as the prophylaxis of arteriosclerosis is concerned, of far more importance is the mode of life of the individual. scarcely any of us lead strictly temperate lives. if we do not abuse our bodies by excessive eating and drinking and so wear out our splanchnic vessels and cause general sclerosis by the high tension thereby induced, we abuse our bodies by excessive brain work and worry with all their multitudinous evils. the prophylaxis of arteriosclerosis might well be labeled, "the plea for a more rational mode of life." moderation in all things is the keynote to health, and to grow old gracefully is an art that admits of cultivation. excesses of any kind, be they mental, moral, or physical, tend to wear out the organism. people habitually eat too much; many drink too much. they throw into the vascular system excessive fluid combined frequently with toxic products that cause eventually a condition of high arterial tension. it has been shown how poisonous substances absorbed from the intestines have some influence on the blood pressure. anything that causes constant increase of pressure should be studiously avoided. mild exercise is an essential feature of prophylaxis. one may, by judicious exercise and diet, make of himself a powerful muscular man without, at the same time, raising his average blood pressure. the man who goes to excess and continually overburdens his heart, will suffer the consequences, for the bill with compound interest will be charged against him. it is a great mistake for any one to work incessantly with no physical relaxation of any kind, and yet, after all, it is not so much physical relaxation that is necessary, as the pursuit of something entirely different, so that the mind may be carried into channels other than the accustomed routes. diversification of interests is as a rule restful. that is what every man who reaches adult life should aim at. hobbies are sometimes the salvation of men. they may be ridden hard, but even then they are helpful in bearing one completely away from daily cares and worries. the man who can keep the balance between his mental and physical work is the man who will, other things being equal, live the longest and enjoy the best health. nowadays the trend of medicine is toward prophylaxis. we give the state authority to control epidemics so far as it is possible by modern measures to control them. we urge over and over again the value of early diagnosis in all chronic diseases, for we know that many of them, and this applies particularly to arteriosclerosis, could be prevented from advancing by the recognition of the condition and the institution of proper hygienic and medicinal treatment. _it is the patent duty of every physician to instruct the members of his clientele in the fundamental rules of health._ recently the president of the american medical association, in his address before the 1908 meeting, urged the dissemination of accurate knowledge concerning diseases among the laity. while this may be done by city and state boards of health, it seems far better for the modern trained physician to work among his own people. with concise information concerning the modes of infection and the dangers of waiting until a disease has a firm hold before consulting the health mender, people should be able to protect themselves from infections and be able to nip chronic processes in the bud. but it is difficult to turn the average individual away from the habit of having a drug-clerk prescribe a dose of medicine for the ailment that troubles him. it is really unfortunate that most of the pains and aches and morbid sensations that one has speedily pass away with little or no treatment. herein lies the strength of charlatanism and quackery. unfortunate, yes, for a man can not tell whether the trivial complaint from which he suffers is any different from the one that was so easily conquered six months ago. but instead of recovering, he grows worse. hope that springs eternal in the human breast, leads him to dilly-dally until he at last seeks medical advice, only to find that the disease has made such progress that little can be done. _instruct the public to consult the doctors twice a year._ the dentists have their patients return to them at stated intervals only to see if all is well. _how much more rational it would be if men and women past the age of forty had a physical examination made twice a year to find out if all is well._ the prophylaxis of arteriosclerosis is moderation in all the duties and pleasures of life. this in no sense means that a man has to nurse himself into neurasthenia for fear that something will happen to him. as one grows in years exercise should not be as violent as it was when younger, and food should be taken in smaller quantities. many forms of exercise suggest themselves, particularly walking and golf. walking is a much neglected form of exercise which, in these modern days with our thousand and one means of locomotion, is becoming almost extinct. there is no better form of exercise than graded walking. to strengthen the heart selected hill climbing is one of the best therapeutic methods that we have. the patient is made to exercise his heart just as he is made to exercise his legs, and as with exercise of voluntary muscles comes increase in strength, so by fitting exercise may the heart muscle be increased in power. a warning should be sounded, however, against over exercise. this leads naturally to hypertrophy with all its disastrous possibilities. men who have been athletes when young should guard against overeating and lack of exercise as they grow older. many of the factors which favor the development of arteriosclerosis are already there, and a sedentary, ordinary life, such as office all day, club in afternoon, a few drinks and much rich food, will inevitably lead to well-advanced arterial disease. karl marx in his famous socialistic platform said: "no rights without duties; no duties without rights." so we may paraphrase this and say: "no brain work without moderate physical exercise in the open air; no physical exercise without moderate brain work." there is yet one other point that is important, the combination of concentrated brain work and constant whiskey drinking. this is most often seen in men of forty-five to fifty-five, heads of large business concerns who habitually take from six to twelve drinks of whiskey daily, and with possibly a bottle of wine for dinner. such men appear ruddy and in prime health but, almost invariably, careful examination will reveal unmistakable signs of arterial disease. there is usually the enlarged heart and pulse of high tension with or without the trace of albumin in the urine. the lurking danger of this group of manifestations has so impressed the medical directors of several of the large insurance companies that a blood pressure reading must be made on all applicants over forty years of age. should high blood pressure be found, the premium is increased, as the expectation of life is proportionately shorter in such men than in normal persons. therefore, let every physician act his part as guardian of health. only in this way is the prophylaxis of arteriosclerosis possible. chapter xiii treatment although it has been rather dogmatically stated (vide supra) that every one who reaches old age has arteriosclerosis, it must not be inferred that absolutely no exceptions to this rule are found. cases are known where persons of ninety years even had soft arteries, and we have seen persons of eighty whose arteries could not be palpated. when infants and children are seen with considerable sclerosis, it proves that, after all, it is the quality of the tissue even more than the wear and tear, that is the determining factor in the production of arteriosclerosis. it would be well if those who can not bring healthy progeny into the world were to leave this duty to those who can. in general the treatment of arteriosclerosis is prophylactic and symptomatic. in the preceding chapter i had something to say about prophylaxis in general; i must again refer to it in detail. arteriosclerosis is essentially a chronic progressive disease, and the secret of success in the management of it is not to treat the disease or the stage of the disease, but to treat the patient who has the disease. to infer the stage of the disease from the feeling of the sclerosed artery, may lead to serious mistakes. persons with calcified arteries may be perfectly comfortable, while those with only moderate thickening may have many severe symptoms. the keynote is individualization. it is manifestly absurd to treat the laboring man with his arteriosclerosis as one would treat the successful financier. the habits, mode of life, every detail, should be studied in every patient if we expect to gain the greatest measure of success in the treatment. one may treat fifty patients who have typhoid fever by a routine method and all may recover. individualizing, while of great value in the treatment of acute diseases, yet is not absolutely essential in order that good results may be obtained. far different is it when treating a disease like arteriosclerosis. one who relies on textbook knowledge will find himself at a loss to know what to do. textbooks can only outline, in the briefest manner, the average case, and no one ever sees the average book case. at the bedside with the patients is the place to learn therapeutics as well as diagnosis. all that can be hoped for in outlining the treatment of arteriosclerosis is to lay down a few principles. the tact, the intuition, the subtle something that makes the successful therapeutist, can not be learned from books. so the man who treats cases by rule of thumb is a failure from the beginning. there are certain general principles that will be our sheet anchors at all times and for all cases. the art of varying the application of these fundamentals to suit the individual case, is not to be culled from printed words. =hygienic treatment= every man is more or less the arbiter of his own fate. granted that he has good tissue to begin life, his own habits and actions determine his span of comfortable existence. no one cares to live after his brain begins to fail, and the failing brain is often due to disease of the cranial arteries. the hygienic treatment resolves itself into advice in regard to prophylaxis. first and foremost is exercise. it has seemed to us that the revival of out-of-door sports is one of the best signs of promise of the preservation of a virile, hardy race. that women, as well as men, indulge in the lighter forms of out-of-door exercise should bring it about that the coming generation will start in life under the most advantageous conditions of bodily resistance. among all the forms of exercise, golf probably is the best. it is not too violent for the middle-aged man, yet it gives the young athlete quite enough exercise to tire him. it is played in the open. one is compelled to walk up and down in pleasant company, for golf is essentially a companionable game, while he reaps the full benefit of the invigorating exercise. the blood courses through the muscles and lungs more rapidly; the contraction of the skeletal muscles serves to compress the veins and so to aid the return of blood to the heart: the lungs are rendered hyperemic, deeper and fuller breaths must be taken; oxidation is necessarily more rapid, and effete products, which if not completely oxidized would possibly act as vasoconstrictors, are oxidized to harmless products and eliminated without irritating the excretory organs. other forms of out-door exercise that can be recommended are tennis, canoeing, rowing, fishing, horseback riding, swimming, etc. tennis is the most violent of all the sports mentioned and might readily be overdone. rowing as practiced by the eights at college is undoubtedly too violent a form of exercise, and may be productive in later life of very grave results. canoeing is a delightful and invigorating exercise. the muscles of the arms, shoulders, and trunk are especially used, the leg muscles scarcely at all. nevertheless, the deep breathing that necessarily comes with all chest exercises aerates every portion of the lungs, and is of great benefit to the whole body. swimming as an exercise has much to recommend it. in this sport all the muscles take part and at the same time the chest is broadened and deepened. all these methods of using the muscles to keep oneself in trim, so to speak, are part and parcel of the general hygienic mode of life that is conducive to a healthy old age. exercise can be overdone, as eating can be overdone. both are essential and yet both can be the means of hastening an individual to a premature grave. when the arteriosclerosis has advanced so far that it is easily recognizable, certain forms of exercise should be absolutely prohibited. such are tennis, rowing and swimming. horseback riding to be allowed must be strictly supervised. at times this may be an exceedingly violent exercise. as an out-of-door sport, there is nothing that equals golf. the physician, knowing the character of the course, and the length of it, can say to his patient that he may play six, nine, twelve, or eighteen holes, depending on the patient's condition. for those who are not able to get out, exercise in the room with the windows open must take the place of out-of-door sports. here the use of chest weights is a most excellent means of keeping up the tone of the muscles. by adjusting the weights, the exercise may be made light, medium, or heavy. every physician should be familiar with the chest weight exercises. they are not as good as open air exercise but they undoubtedly have been the means of saving years of life to many patients with arterial disease. there comes a time when all forms of exercise must be prohibited on account of the dyspnea, edema, dizziness, etc. it seems unwise to keep such a patient in bed, even though the edema be considerable. once on his back in bed he becomes weak, and the danger of edema of the lungs or hypostatic congestion of the bases, with subsequent bronchopneumonia, is very great. such patients may be allowed to sit up in a comfortable chair with the legs supported straight out on a stool or other chair. the half reclining position is not easy to assume in bed. considerable ingenuity must often be exercised by the physician in making the patient comfortable without increasing the symptoms from which the patient suffers following the least amount of exercise. although such persons can not exercise actively, they should have passive exercise in the form of massage, carefully given, so that no injury is done to the rigid vessels. it is possible to rupture a vessel, the walls of which are encrusted with lime salts, and full of small aneurysmal dilatations. every patient must be watched carefully and measures instituted for the individual. =balneotherapy= as a tonic and invigorator, the cold or cool bath (shower or tub), in the morning on arising can be highly recommended. it promotes skin activity, is a stimulant to the bowels and kidneys and to the general circulation, besides being cleansing. we find today that the morning bath has become such a necessity to the average american that all new hotels are fitted with private baths, and old hotels, in order to get patronage, are arranging as many baths connected with sleeping rooms as is possible. our generation assuredly is a ruddy, clean-bodied one. what the actual results of this out-door life and frequent bathing will be for the race remains to be seen, but one can not but feel that it must build up a stronger, more resistant race of people, who not only enjoy better health than did their forefathers, but enjoy it longer. not every one can stand a cold bath. it is folly to urge it on one to whom it is distasteful, or on one who does not feel the comfortable glow that should naturally result. for the well, or those with a tendency to arteriosclerosis, or those in whose families there have been several members who had early arteriosclerosis, such proceedings as recommended could not be improved upon. however, for the person who has well recognized sclerosis, only warm baths should be advised, and these not daily. the water should be at a temperature of 90-95â° f. care should be taken that persons sent to spas be cautioned against hot baths. it is not inconceivable that the increased force of the heart beat that accompanies a hot bath might be sufficient to rupture a small cranial vessel. hence, turkish and russian baths should be most unqualifiedly condemned. as a matter of fact, persons vary so in their habits with regard to bathing that what might suit one person would do another much harm. =personal habits= the personal habits of the individual, more than any other factor, determine whether or not arteriosclerosis sets in early in his life. the man or woman who is moderate in eating and drinking, sees that the kidneys are kept in good condition, and attends strictly to regularity of the bowels, lays a good basis for the measure of health which is so essential for happiness. it has been shown that sclerosis of the splanchnic vessels may be due to constant irritation of toxic products elaborated in digesting constantly enormous meals. in obstinate constipation, many poisons, the nature of which we do not know, are absorbed and circulate in the blood. we have not sufficient data to prove that constipation favors the production of arteriosclerosis, but our impression has been that it does favor it. constipation can often be relieved by a glass of water before breakfast, a regular time to go to stool, and abdominal massage or exercises. some maintain that it is a bad habit only, and can be readily overcome. whatever is done, avoid leading the patient into the drug habit, for the last state of the patient will be worse than the first. habits of sleep are not of such great importance. most persons get enough sleep except when under severe mental strain. most adults need from seven to eight hours' sleep, although some can do all their work and keep in prime health on five or six hours' sleep. tobacco has been accused of causing many ills and has been thereby much maligned. we can not see that the use of tobacco in any form in moderation is harmful to most men. undoubtedly the blood pressure is raised when mild tobacco poisoning occurs, and individual peculiarities of reaction to the weed are multitudinous. but to condemn offhand its use is the height of folly. there is no reason why the arteriosclerotic who has always used tobacco in moderation, should not continue to use it, whether he smoke cigarettes, cigars, or pipe. his supply should be decreased, but there is no sense in depriving a man of one of the solaces of life, unless, as is sometimes the case, abstinence is easier for the patient than moderation. as for alcohol, opinions differ widely.[19] some see in alcohol one of the most frequent causes of arteriosclerosis; others do not believe that the part played by alcohol is a serious one, only in conjunction with other poisonous substances is it dangerous. probably unreasoning fanaticism has had much to do with the wholesale condemnation of alcoholic beverages. the general effect of alcohol is to lower the blood pressure by causing marked dilatation of all the vessels of the skin. true, the alcohol circulates in the blood, and is broken up in the liver, and this organ would seem to bear the brunt of the harm done. alcoholic drinks in moderation, i do not believe have any deleterious effect on health. on the contrary, i believe that they may in some cases assist digestion and assimilation. indiscriminate indulgence is to be condemned, as is overindulgence in exercise or eating. what may be moderate for a, might be excessive for b. every man is then the arbiter of his own fortune and within his own limits can indulge moderately (a relative term after all) without fear of doing himself harm. in advanced arteriosclerosis it is necessary to decrease the supply of alcohol just as it is necessary to cut down the food supply. this must rest entirely on the judgment of the physician, who must not act arbitrarily, but must have his reasons for every one of his orders. [19] discussion of alcohol at present has value only as it relates to the past. the present is dry. the future is in the lap of the gods. =dietetic treatment= most persons eat too much. we not only satisfy our hunger, but we satisfy our palates, and, instead of putting substantial foodstuffs into our stomachs, we frequently take unto ourselves concoctions that defy description. foodstuffs are composed of one or all of three classes: (1) proteins, (2) fats, (3) carbohydrates. as examples of the first are beef and white of egg; of the second, the oils, butter, lard; of the third, sugar, potato, beet, corn, etc. the physiologists and chemists have shown us that both endogenous and exogenous uric acid in excess will cause a rise of blood pressure, but the bodies most concerned in the production of elevated blood pressure are the purin bodies, those organic compounds which are formed from proteins and represent chemically a step in the oxidation of part of the protein molecule to uric acid. red meat contains more of the substances producing purin bodies than any other one common foodstuff, and for this reason the excessive meat eater is, _ceteris paribus_, more apt to develop arteriosclerosis comparatively early in life. the fats and carbohydrates contain practically no substances that react on the body of the ordinary individual in a deleterious manner during their digestion. the extra work that is put on the heart by the formation of many new blood vessels in adipose tissue is the only harmful effect of overindulgence in these foodstuffs. it has been found that nitrogen equilibrium can be maintained at a wide range of levels. formerly 135-150 gms. of protein daily were considered necessary for a man doing light work. now it is known that half that amount is sufficient to keep one in nitrogenous equilibrium, and to enable one to keep his weight. a person at rest requires even less than that. one who is engaged in hard physical labor burns up more fuel in the muscles, and so must have a larger fuel supply. although we habitually eat too much we drink too little water. for those who have any form of arterial disease an excess of fluid is harmful, as the vessels become filled up and a condition of plethora results, which necessarily reacts injuriously on the heart and circulation. the drinking of a glass of water during meals is, in the author's opinion, good practice. the water must be taken mouthful at a time, and not gulped down. if this is done, there results sufficient dilution of the solid food to enable the gastric juices successfully and rapidly to reach all parts of the meal. some are in favor of a rigid milk diet for those who have arteriosclerosis. some men have lived on nothing but milk for several years and have not only kept in good health, but have actually gained weight and led at the same time active lives. it has been held by others that rigid milk diet is positively harmful on account of the relatively large quantity of calcium salts that are ingested. this was thought to favor the deposition of calcareous material in the walls of the already diseased arteries. while possibly there may be some danger of increased calcification, the majority of clinicians are in favor of a milk cure given at intervals. thus the patient is made to take three to four quarts daily for a period of a month. there is then a gradual return to a general diet, exclusive of meat, for several weeks, then another rigid milk diet period. if we are bold enough to follow metschnikoff in his theories of longevity, we might advise resection of the large intestine, on the ground that it is an enormous culture tube that produces prodigious amounts of poisonous substances which are thrown into the general circulation. to combat such a grave (?) condition as the carrying of several feet of large intestine, we are recommended to take buttermilk or milk soured by means of the _b. acidus lacticus_. clinical experience has taught that in arteriosclerosis buttermilk is of great value, whether it be the natural product, or made directly from sweet milk by the addition of the bacilli. the latter is a smoother product and has, to my mind, a delightful flavor. it may be diluted with vichy or plain soda water. cases that can not take milk or any other food will often take buttermilk, and do well on this restricted diet. from two to four quarts daily should be taken. it should be drunk slowly as should milk. =medicinal= it has long been thought that the iodides have some specific effect on the advancing arteriosclerosis, checking its spread, if not really aiding nature to a limited restoration of the diseased arteries. it is possible that the eulogies upon the iodides owe their origin to the successful treatment of syphilitic arteriosclerosis, in which condition these drugs have a specific action. however that may be, there is no doubt that the administration of sodium or potassium iodide is good therapeutics in cases of arteriosclerosis. unfortunately many persons have such irritable stomachs that they can not take the iodides, even though they be diluted many times. they may be made less irritating by giving them with essence of pepsin. unless the case is syphilitic, it is doubtful whether it is of value to increase the dose gradually until a dram or even more is taken three times daily after meals. usually a maximum dose of ten grains seems to be quite sufficient. this may be taken three times a day, well diluted, for three months. there follows a month's rest, then the treatment is resumed for another period of three months, and so on. either sodium or potassium iodide in saturated solution may be given. the sodium salt is possibly less irritating, and contains more free iodine than the potassium salt, although the latter is more generally used. the strontium iodide may also be used. one sees a patient now and then who can not take the iodides, however they may be combined. for such patients one may obtain good results with iodopin, sajodin, or other of the preparations put up by reputable firms. personally i have never yet seen a patient who could not take the ordinary iodides in some form or other, and i am opposed to ready made drugging. the action of the iodides is to lower the blood pressure, and they are of greatest value when the blood pressure is high, and when headache and precordial pain are present. when the case is moderately advanced, very mild doses, gr. 1/2, morning and evening, of the thyroid extract may be given. it is generally believed that the internal secretion of the thyroid and the adrenal are antagonistic. that the thyroid secretion lowers blood pressure in certain forms of hypertension is certain, possibly on account of its iodine content. some combinations of iodine and thyroid such as the iodothyroidin have been used and have had some measure of success attributed to them. hypertension does not always demand active measures for its reduction. viewed from the physiologic standpoint, hypertension is but the expression of a compensating mechanism which is designed to keep the blood moving through narrowed channels. heart hypertrophy then is absolutely essential to the maintenance of life. it has been said that the highest blood pressures occur in chronic disease of the kidneys. the poisonous substances produced in the kidneys must exert their action through absorption into the general blood stream. this toxin may be completely eliminated, if we accept as our criterion the reduction of tension to normal together with the complete return of the affected individual to health. a concrete example is as follows: a man aged 44 years was brought to the milwaukee county hospital in coma. his systolic blood pressure was over 280 mm. hg, diastolic 170 mm., his urine contained considerable albumin and many casts. he had general anasarca. venesection was done at once and 300 c.c. blood obtained. immediately following this operation the pressure was 210-150, but within twelve hours it was again above 280-170. he was given no medication to reduce pressure except that he was freely purged. he was given a steam sweat bath daily. frequent blood pressure readings were taken. within seven days the pressure was 130-86. he had, in the meantime, completely recovered from his symptoms. he was kept in the hospital for two weeks longer assisting in the work on the ward, and he was discharged with a pressure (systolic) between 130 and 136 diastolic 80-84. the treatment was rest in bed, free purging, venesection, and sweat baths, simple but exceedingly effective. should there be actual indications for reducing the blood pressure, i must admit that it can not always be done. the majority of cases will do well on the sodium nitrite or erythrol tetranitrate. however, these do not always lower blood pressure and keep it within normal limits. when a man has very high tension we do not wish to reduce it to what it should normally be for the age of the patient, as symptoms of collapse might set in at any time under such conditions. observations made with the sphygmomanometer[20] show that the effect of nitroglycerin is transient or of no effect except in doses which are relatively enormous (one drop of the one per cent solution given every hour). sodium nitrite may lower the blood pressure but the effects will have worn off in two hours. it is the same with erythrol tetranitrate. sodium sulphocyanate in doses of from one to three grains three times a day is highly recommended by some. my own experience with it does not lead me to believe that it is of any great value in hypertension. it, however, may be tried. benzyl benzoate has been used recently to reduce the high blood pressure of hypertension. macht has reported some success. in the author's hands it has been efficacious in a few cases. as long as the patient takes the drug the pressure may be slightly reduced, but upon the withdrawal of the drug the pressure returns to its former level. it is well worth a trial and further experimentation may reveal better methods of administration. the dose is from 2 to 6 c.c. mixed with water at intervals. [20] miller, jos. l.: hypertension and the value of the various methods for its reduction. jour. am. med. assn., 1910, liv, p. 1666. in the hypertension of the menopause some have had success with large doses of corpus luteum extract. as a matter of fact the drug treatment of hypertension, when it becomes necessary to treat this condition with drugs, has suffered a notable set-back since more careful control has been made with the blood pressure instruments. in giving any of the depressor drugs their action should be controlled by blood pressure measurements, for only in this way can we be sure that the drug is exerting its physiological effect and we may expect results. the individual reaction to these drugs varies greatly and no rule for dosage can be dogmatically laid down. the only successful therapy is rigid individualization. this is the keystone to treatment in cases of arteriosclerosis and high tension. it must not be inferred from what has been said that the nitrites are of no value. they are of decided value but they have their limitations. the most evanescent of these drugs is amyl nitrite. this is put up in the form of capsules, or pearls, containing from one to three minims. when it is desired to dilate the peripheral vessels suddenly, one or two of these capsules are broken in a cloth held to the nose. the effect is almost instantaneous. there is flushing of the face and other peripheral vessels, particularly near the head, denoting a relaxation and widening of the bed of the blood stream, and a consequent decrease in pressure in the arteries. these effects are over in a short while. it is only used in attacks of cardiac spasm, as in angina pectoris. nitroglycerin, the spiritus glonoini of the u. s. p., acts in about the same manner as amyl nitrite but the effects last usually a trifle longer. one drop of the one per cent solution may be given every hour until physiologic effects are produced. it may be given hypodermically. this may be a means of reducing pronounced high tension. this drug has been found of benefit especially in cases where arteriosclerosis combined with chronic nephritis causes cardiac asthma. the other drug which may be of service in these conditions, one whose sphere of action is somewhat broader, because its effects are more lasting, is sodium nitrite. this is given in water in doses of one to three or five grains every four hours. some have objected to the use of this drug, but my experience has made me place considerable confidence in its harmlessness, provided that the patient is carefully watched. this, however, applies to all of the nitrite compounds. my experience with erythrol tetranitrate is not large. it may be used in place of sodium nitrite. for a mild case, one often finds that sweet spirits of niter is sufficient to control the pressure and relieve the distressing symptoms, and it is undoubtedly the least harmful of all the nitrites. drugs that are of great value, but of which little is noted in textbooks, are aconite and veratrum viride. both of these drugs are well known to be marked circulatory depressors. veratrum viride in my experience should be very cautiously used, and never used unless a trained attendant is constantly at hand. with regard to aconite i have no such feeling, and a mixture of tincture of aconite and spiritus etheris nitrosi may be given for several weeks with no fear of doing any harm. personally, of all the drugs mentioned, i prefer the nitrite of sodium or the combination just given. they may be advantageously alternated. my own feeling is that the most successful means of treatment of acute high tension is without the use of drugs. the most important measure is absolute rest in bed. this often suffices to lower the blood pressure and to arrest the symptoms produced by high tension. venesection i believe is also of value. true the arterioles appear to contract almost immediately upon the lessened quantity of blood, or there is immediate interchange of serum from the tissues which brings the blood volume back to the original amount. whatever happens the pressure is not greatly reduced, at times not reduced at all, but often the symptoms are relieved. hot packs or sweat baths assuredly do reduce the pressure in many cases. this seems to me to be an exceedingly valuable measure. finally the diet should be nourishing, but very light, not too much fluid should be ingested, and the bowels should be freely opened. with the fibrolysin of merck, i have had no experience. some men assert that they have had good results from its use, but on the whole the evidence is not highly favorable. morphine is invaluable. no drug is of such value in the nocturnal dyspneic attacks that occur in the late stages of arteriosclerosis when the heart or the kidneys are failing. morphine not only relaxes spasm and quiets the cerebral centers, but is an actual heart stimulant under such conditions, and should never be withheld, as the danger of the patient's becoming addicted to its use is more fanciful than real. however, morphine, at times, suppresses the secretion of urine. so that if after trial the urine becomes scanty and the edema increases, recourse must be had to other drugs. the various hypnotics may be used with caution. one which seems to be very useful is adalin. as heart stimulants, one may use strychnine, spartein, caffein, or camphor. in desperate cases, where a rapidly diffusible stimulant is needed, a hypodermic syringeful of ether may be given, and repeated in a short while. several years ago a so-called serum was brought out by trunecek which was said to have a favorable effect on the metabolism of the vessel walls. it was given at first hypodermatically or intravenously but the former method was painful. it was later stated that given by mouth it acted just as well. the results with the trunecek serum have not come up to the expectations that the early favorable reports promised. the original serum was composed as follows: nacl, 4.92 gm.; na_2so_4, 0.44 gm.; na_2co_3, 0.21 gm.; k_2so_4, 0.40 gm.; aqua destil. q. s. ad. 100.0 c.c. later this was modified for internal use to the following prescription: r_{x} natrii chlor. 10. gm. natrii sulphat. 1. gm. natrii carbonat. 0.40 gm. natrii phosphat. 0.30 gm. calcii phosphat. magnesii phosphat. aa. 0.75 gm. m. ft. cachets no. xiii. the contents of every cachet corresponds to 15 c.c. of the fluid serum or to 150 c.c. of blood serum. the preparation called antisclerosin consists of the salts contained in the serum. as to its efficacy, i can not judge, as i have never felt that it was worth while to use it. reports of cases in which it has been tried do not speak very highly of it. in the general treatment of arteriosclerosis, there is no one factor of more importance than the regular daily bowel movement. attention to this may save the patient much discomfort and even acute attacks of cardiac embarrassment. the choice of the purgative is immaterial, with this reservation only, that the mild ones, such as cascara, rhubarb, licorice powder and the mineral waters, should be thoroughly tried before we resort to the more drastic purgatives. plenolphthalein in 3 to 5 grain doses acts remarkably well in some people as a pleasant laxative. agar-agar with or without cascara may be useful. liquid paraffin under a variety of names is a most useful and efficacious laxative. as its action is purely mechanical it may be taken indefinitely without doing harm to the intestinal musculature. the old lady webster dinner pill is an excellent tonic aperient. when the heart is embarrassed and edema of the legs and effusion into the serous cavities have taken place, then it becomes necessary to use the drastic purgatives that cause a number of watery movements. epsom salts given in concentrated form, elaterin gr. 1-12, the compound cathartic pill, blue mass and scammony, or even croton oil may be used. since the observation of a greatly congested intestine from a patient who had been given croton oil, i have ceased to use this purgative, and i doubt much whether its use is ever justifiable in these cases. the management of the ordinary case of arteriosclerosis resolves itself into a careful hygienic and dietetic regime with the addition of the iodides, aconite, or the nitrites. a diet consisting of very little meat, alcohol in moderation or even absolutely prohibited, and not too much fluid should be prescribed. condiments and spices should also be used sparingly. cold baths, shower baths, cold and hot sheets alternating, are of great benefit in assisting the heart to do its best work by making the large capillary area of the skin more permeable. it is not true that such baths raise the blood pressure so markedly. certain acts, as sneezing, violent coughing, etc., increase the blood pressure much more than judicious bathing. =symptomatic treatment= the fact that arteriosclerosis really loses much of its own identity and, in later stages, becomes merged with the symptomatology of the diseases of various organs, as the kidney, brain, heart, compels us, for completeness' sake, to say a few words about the treatment of these complications. one of the results of arteriosclerosis of the coronary arteries, angina pectoris, demands prompt treatment. in the acute attack, the chief object is to relieve the spasm and pain. pearls of amyl nitrite should be inhaled, and morphine sulphate with atropine sulphate given hypodermatically at the very earliest moment. it is senseless to withhold morphine. the only possible reason for withholding it would be uncertainty as to the diagnosis. it is probably better to err on the safe side, and should the case prove to be one of pseudo angina, in the next attack sterile water can be given instead of the morphine and atropine. when a patient is seen in the condition of broken compensation with the much dilated heart, anasarca, dyspnea and suppression of urine, there is no better practice than venesection. especially is this valuable when the tension is still fairly high and the individual is robust. following the abstraction of six to eight ounces of blood (300-500 c.c.)[21] the whole picture changes, so that a man who a short while before was apparently at death's door, notices his surroundings and takes an interest again in life. this should be followed up with thorough purgation, and cardiac stimulants should be ordered. in such cases digitalis is useful, but its action is never so striking as in cases of this general character due to uncompensated valvular disease. it must be remembered that in arteriosclerosis the changes in the myocardium must be of a considerable grade for the heart to give away. therefore, digitalis can not be expected to act on a diseased muscle as it acts on a comparatively healthy muscle. it is only in such cases of broken compensation that digitalis should ever be used. [21] i have taken as much as 1700 c.c. from a large man. he recovered and went back to work. digitalis is not a general vasoconstrictor as used to be taught. its action on the kidney is actually a vasodilator one. and in its action on the heart the digitonin dilates the coronary arteries, according to macht, while the digitoxin acts on the heart muscle. overdosing with digitalis has produced partial heart block in many cases. it is absolutely contraindicated in stokes-adams syndrome. there are, however, some cases, especially those with transudations, when digitalis may be carefully tried even though high tension be present. it is sometimes of advantage to combine digitalis with the nitrites although they are said to be physiologically incompatible. still another drug, that is of great value in conditions such as have been described, is diuretin. this may be given in capsule or tablets, grs. x. three times daily. there is only one caution to express in the use of this drug. it should not be given when the kidneys are the seat of chronic inflammatory changes; in fact, actual harm may be done by administering the drug under such conditions. the same is true even to a greater extent with theocin. this is a powerful diuretic. if given by mouth it should be well diluted as it is most irritating to the stomach. it is best given intravenously in doses of two and a half to three grains dissolved in five to six cubic centimeters of distilled water. one must be reasonably sure that the kidneys are not the subject of chronic disease and are functionally, therefore, below par. the intravenous dose should not be given oftener than once in four days. for the pain in aneurysm, nothing (except, of course, morphine) is so valuable as iodide of potassium. patients who are suffering agony, when put to bed and given ki grs. x. three times a day, soon lose all the distressing symptoms. this applies particularly to aneurysms of the arch of the aorta. when the sclerosis has affected the cerebral arteries to such an extent that symptoms result, the case is, as a rule, exceedingly grave. not much can be done except to relieve the headaches and keep down the blood pressure, if this is high, by means of rest in bed, the iodides, aconite, or the nitrites. the cases of transient monoplegias or hemiplegias can be much relieved by careful hygienic measures and judicious administration of drugs. much ingenuity is sometimes required to overcome the idiosyncrasies of patients, but care and patience will succeed in surmounting all such difficulties. the treatment of intermittent claudication is the treatment of arteriosclerosis in general. sometimes the circulation in the affected leg or legs is much helped by daily warm foot baths. light massage might be tried and the galvanic current may be used once or twice daily. there are a few distressing symptoms that occur usually late in the disease, when complications have already occurred, which frequently baffle the therapeutic skill of the physician. the chief of these--insomnia, dyspnea, and headache--may not be late manifestations, but insomnia and headache are frequently associated with the moderately advanced stages of arteriosclerosis. at times all the symptoms seem to be due to the high tension, the relief of which causes them to disappear. there are, unfortunately, times when high tension is not responsible for the headache and insomnia. under these circumstances such drugs as trional, veronal, amylene hydrate, ammonol, etc., may be tried until one is found which produces sleep. for the headaches, phenacetin, alone or in combination with caffein and bromide of sodium, may be tried. acetanilid, cautiously used, is at times of value. there have been cases of arteriosclerosis with low blood pressure, accompanied by severe headaches, that have been relieved by ergot. codeine should be used with care, and morphine only as a very last resource. great care must always be exercised in giving drugs that depress the circulation, for it is easily conceivable that more harm than good can come from injudicious drugging. chapter xiv arteriosclerosis in its relation to life insurance the value of the early recognition of cases of arteriosclerosis and hypertension has been spoken of within, but it needs to be further emphasized. there is perhaps no class among physicians to whom is afforded a better opportunity of seeing early cases than the medical examiners of life insurance companies. the relationship between a patient and the physician whom he consults, and the applicant for life insurance and the examiner are diametrically opposite. in the former the patient desires to conceal nothing and the physician is called upon to diagnose and treat disease. in the latter the applicant, a presumably healthy person, may have much to conceal and the examiner is there to pass upon the state of health. the question is this--"is the applicant now in good health?" it becomes then of vital importance for the examiner to be able to detect among other abnormal conditions the incipient signs of arteriosclerosis and of hypertension. parenthetically it may be stated that arteriosclerosis and hypertension are not one and the same disease as has been so frequently insisted upon within; the former may occur without the latter but the latter can not from its very nature be present for long without arterial thickening supervening. it is necessary in discussing the question here to group the two conditions together in order to prevent needless repetition. such a case as the following is common. a successful business man of forty-four years was brought to me by an agent in 1905 for examination. the man was six feet tall, weighed 218 pounds, had a ruddy color and looked to be the picture of health. he was not strictly intemperate, he never became intoxicated, but every day he drank three or four whiskies and often he had a bottle of wine for dinner in the evening. when he was examined his pulse was of good quality and owing to the fleshiness of the wrist it was difficult to say positively whether the radial artery was sclerosed or not. in the heart no murmurs were heard, and it was difficult to be sure that the left ventricle was enlarged. there was, however, a slight but definite accentuation of the second sound at the aortic cartilage which might readily have been overlooked had the patient not been stripped and a careful examination made with the stethoscope. upon taking the blood pressure it was found to be from 170-175 mm. of hg. the urine specimen examined at the visit was normal, no casts were found. the applicant was seen at his home and the blood pressure measured. it was again the same. he was seen a third time and practically the same systolic blood pressure was found. under protests from all the agency staff the man was declined. two years later he died of apoplexy. the man was angry at being refused. instead of looking the matter squarely in the face he thrust aside the idea that there was anything the matter with him. he had never had one ill day in his life, his forebears had lived to ripe old age, and he was sure that he knew more about himself than the examiner. had this applicant showed a sense of reasonableness he should have been grateful to the doctor for calling his attention to a condition which surely would sooner or later prove either fatal itself or lead to some fatal lesion. it was learned that this man had gone directly to his family physician who laughed at such nonsense as had been told the (now) patient by the examiner. another illustration of a slightly different type of case is afforded in the following history. a man of fifty years of age, five feet ten in height and 164 lbs. in weight, was brought for examination. in his youth there was a history of a mild attack of scarlet fever. he was almost a total abstainer, rarely taking liquor in any form. physically he appeared to be an excellent risk. however, on examining the heart it was found that there was slight hypertrophy with an accentuated second aortic sound at the base, and the blood pressure was 180 mm. of hg. some sclerosis of the radial arteries was found. one company had refused him on account of albumin in the urine. there was none in the first specimen which was passed while in the office. the specific gravity was 1014. a morning specimen was obtained and contained a trace of albumin. several specimens were then examined. some contained albumin, some had no albumin content. the man was declined; no protests from the agent as albumin had been found. there was something tangible in that. had the applicant been refused on account of his high tension, sclerosis of the radials, and slightly enlarged heart there would undoubtedly have been protests. and yet an applicant revealing such a state of the cardiovascular system without albumin in the urine should unhesitatingly be declined. attention has been called to hypertension as an early, and some think an invariable, sign of chronic nephritis. my own experience has confirmed me in the belief that in hypertension the kidneys are often the seat of chronic interstitial changes. careful palpation of the radial and brachial arteries will in every case reveal more or less thickening. there is yet another group of cases which the examiner sees as healthy subjects, namely those cases of sclerosis of the peripheral arteries without sclerosis of the aorta and without high tension. in such cases the radials, brachials, temporals and other superficial arteries are readily palpable, sometimes even revealing irregularities along the course of a vessel. such cases are not subjects for insurance. the recognition of such a condition is of great importance to the one who has it and he should be urged to go to his regular physician for thorough examination. should the physician ridicule the idea, as has happened to me more than once when i was actively engaged in insurance work, the examiner has done his full duty to the company, the applicant, and himself. a life insurance examiner has a difficult position to fill. he has four people to satisfy; the applicant, the agent, the medical director and himself. the straight and narrow path of strict honesty is his only salvation. by being honest with himself he necessarily gives a square deal to the other three parties. no applicant who has palpable arteries or hypertension can be considered a first class risk. it can not be denied that men with arteriosclerosis live to an advanced age and may even outlive those who have apparently normal arteries, but the average life expectancy at any age for an arteriosclerotic is less than that for a normal person. the apparently healthy applicant who learns for the first time when examined for life insurance that he has the early or moderately advanced signs of arterial disease, should thank the agent and examiner for showing him the danger signals ahead. the sensible man then orders his life so that he puts as little strain on his heart, arteries, and kidneys as possible and may add many years to his life. it is on account of this very insidiousness of onset that i have elsewhere urged as a prophylactic measure the examination every six months of all persons over forty years of age. i am more and more convinced that it is of vital importance to the health of the public. as i have remarked, the average man consults his dentist at least once a year so that no tooth may be so far diseased that it can not be saved. it is purely a means of preserving the teeth. why not do the same with the whole body? of what use is it to save the teeth and lose the body? it seems to me that the great army of life insurance examiners are in an enviable position in their ability to add years of life to many men and women. i doubt whether they realize their importance in the campaign for health. i should urge life insurance companies not to employ recent graduates unless they have had at least a year's hospital experience. for the company as well as for the individuals i believe that there is a prognostic sense which the examiner should have and this can only be acquired by experience. i believe that arteriosclerosis and hypertension are increasing for the reasons which have been given in another chapter. there can be no doubt that when these conditions are recognized long before symptoms would naturally supervene, men and women would not only live longer but also die more comfortably and many very likely would be carried off by some disease having no relationship whatever to arteriosclerosis. slight enlargement of the heart downward and to the left, accentuation of the second aortic sound at the base, a full pulse, arteries which are palpably thickened, increased blood pressure are signs to which attention must be paid. when the peripheral arteries are palpable they are not always sclerosed. the radial artery, the one usually palpated, may lie very close to the bone in a thin person. under these conditions the artery can be easily felt. it is better then to palpate for the brachial as it lies beneath the inner edge of the biceps muscle. should this artery be felt then very probably sclerosis is present. opinion as to whether or not sclerosis is present, when it is slight, may differ. it is difficult at times to say definitely. should such be the case the applicant should be most carefully questioned as to his family and past history, the heart should be carefully outlined by percussion and the blood pressure should be taken, both the systolic and diastolic pressures. the urine should be examined with particular care. i am aware that the average examination for life insurance is not made with the care which is bestowed upon a patient. yet i see no reason why the same attention to detail should not be given in one as in the other. the examination of the great majority of applicants can he made in a short time, as there is no question of latent chronic disease. when the exception turns up he should be given a searching examination and a full report should be sent to the medical director. only in this way will it be possible to weed out the undesirable risks. on the surface it does not seem to require any great diagnostic acumen to be a life insurance examiner. in the old days of many of the companies there were no examiners. the applicant was brought before the president or other appointed official and he was passed or rejected on his general appearance. this has changed, and now the medical department with its scores of examiners in the field is a well organized department. it seems to me that the examiner should be an exceedingly able diagnostician and prognosticator. there is no telling when he may be called upon to pass judgment on a borderline case. from personal experience i know how difficult it is to make a decision in some cases. these suspicious cases after a careful examination had better be passed by the examiner and a supplementary report sent to the medical director containing unbiased details. but no applicant with readily palpable arteries, even though the blood pressure be normal, should be considered a first class insurance risk. the question of the value of the diastolic pressure reading in examinations for life insurance is not yet settled to the satisfaction of all medical directors. certain medical directors with clinical experience behind them, lay great stress on the increased diastolic pressure and consider a persistent diastolic of 100 mm. really more significant as an indication of hypertension than a systolic pressure of 160 mm. other directors pay little or no attention to the diastolic reading. should an applicant show a systolic above the average normal on several successive readings, he is declined. when one takes into consideration the psychic effect of knowing that he is being examined for high blood pressure, it seems unfair to refuse insurance on such grounds as is constantly done. up to the present there are no extensive series of life-expectancy tables in which hundreds of thousands of cases are analyzed from the diastolic pressure values. there are many such tables for the systolic pressures alone. in the tabulation of such statistics one must not lose sight of the important fact that the figures are taken by thousands of men of varying capacity and different degrees of intelligence. such studies to be of any real value must be taken from records made at the home offices by capable men. we shall await these tables with interest. in the meantime we must be permitted to have the impression that the diastolic pressure has been much neglected. this has no doubt been due to the difficulty of measuring it with any degree of accuracy. now with the auscultatory method and the correct place to read the diastolic pressure the results of blood pressure estimations should begin to have some value for statistical data. clinically the diastolic is probably more important than the systolic. until proof is brought to the contrary we shall believe that in life insurance examinations it has the same importance. chapter xv practical suggestions the time spent in obtaining a careful history of a case is time well spent. often the diagnosis can be made from the history alone, the physical examination merely adding confirmation to the data already obtained. the younger the patient who has arteriosclerosis, the more probable is it that syphilis is the etiologic factor. a denial of infection should have little weight if the history of possible exposure is present. miscarriages in a woman should arouse the suspicion of lues in her husband. the complement-fixation reaction will often clear up an apparently obscure diagnosis. there are various ways of examining a patient but there is only one right way; the examination should be made on the bare skin. however skillful one may be in the art of physical diagnosis, he can gather few accurate data by examining over the clothes even if he use a phonendoscope. the immoderate eater is laying up for himself a wealth of trouble at the time when he can least afford to bear it. the ounce of advice in time is worth more to him than the pounds of medicine later. it is a wise maxim never to drive a horse too far. apply that to the human being and the rule holds equally well. there may be no symptoms in a case of advanced arteriosclerosis. do not on that account neglect to advise a patient in whom the disease is accidentally discovered. many a man owes a debt of gratitude to the life insurance examiner. he rarely feels grateful. when a competent ophthalmologist refers a case to a general practitioner with the statement that he believes from the appearance of the fundus of the eye that arteriosclerotic changes are present over the body, the case should be most carefully examined. the earliest diagnoses are not infrequently made by the ophthalmologist. it is the part of wisdom never to have such a firmly preconceived idea of the diagnosis that facts observed are perverted in order to fit into the diagnosis. let the facts speak for themselves. beware of the snap diagnosis. even in a case of well-marked arteriosclerosis when the diagnosis seems to be written in large letters all over the patient, go through the routine. nine times out of ten this may seem needless. the tenth time it saves your conscience and reputation. always consider that you are examining a tenth case. gradual loss of weight in a person over fifty years old should arouse the suspicion of arteriosclerosis. do not call the nervous symptoms displayed by a middle-aged man or woman neurasthenia until you have ruled out all organic causes, particularly arteriosclerosis. when palpating the radial artery, always use both hands according to the method already described. pay attention to the superficial or deep situation of the artery. the examination of one specimen of urine does not give much information, especially if it should be found to contain no abnormal elements. fairly accurate data may be gathered from the mixed night and morning urine; most accurate data from the twenty-four hour specimen. to be of any real value there should be frequent examinations of the day's excretion. in measuring the day's output a good rule is as follows: begin to collect urine after the first morning's micturition and collect all including the first quantity passed the next morning. it is best to examine the centrifugated urine for casts even though no albumin be present. it is useless to look for casts in an alkaline urine. casts are not infrequently found in chemically normal urine from a middle-aged patient. other things being normal, the finding has no significance. the kidneys must be carefully tested functionally. blood pressure readings should always be taken with the patient in the same posture at every estimation. at the first examination it is advisable to take readings from both brachial arteries. let the patient sit comfortably and relax all muscles. differentiate as soon as possible between the uncompensated heart caused by valvular disease and that caused by arteriosclerosis. there is a difference in prognosis. both give the same symptoms, and are treated similarly until compensation returns; thereafter the management of the two forms is different. aortic incompetence that comes on late in life is generally the result of curling of the free margins of the valves caused by syphilitic arteriosclerosis. prognosis is grave because of the fact that the heart muscle also is the seat of degenerative changes and compensatory hypertrophy is established with difficulty. when laying down a regime for a patient, consider his disposition, and individualize the treatment. remember that exercise is an essential feature of the hygiene of the patient's life but do not forget to be explicit about the amount and character of the permissible exercise. in the prophylaxis of arteriosclerosis, a rational mode of living is the all-important factor. as a rule, the less meat one eats, the less is the liability of arterial degeneration as age advances. the exceptions to this rule are many, and probably depend upon the character of the "vital rubber" with which the individual begins life. the diet in well-marked cases of arteriosclerosis should be carefully selected with regard to its nutritive and non-irritating character. animal proteins should be sparingly used. milk should have an important place in the dietary. no drug relieves the pain of uncomplicated aneurysm as surely as iodide of potassium. iodides frequently upset the stomach. be cautious in the use of them. the irritable stomach may turn the scales against your patient. use cardiac stimulants with care and judgment. if all the valuable ammunition is used up at first, the fight will be lost. use digitalis with especial care. its chief usefulness is in steadying the decompensated heart, improving the conduction of impulses, and increasing the tone of the cardiac muscle. _it should never be given to patients with very slow pulses, the subjects of stokes-adams syndrome._ digitalis has been found to produce partial to complete heart block when therapeutically administered. remember that in the uncompensated heart morphine not only eases the oppressive dyspnea, but also steadies and stimulates the heart. see to it that the patient has a daily movement of the bowels. in the early stage try the effect of liquid paraffin or of the mineral waters such as pluto, or hunyadi janos, or artificial carlsbad salts (sprudel salts). these last can be made as follows: sodium chloride, ounce i; sodium bicarbonate, ounce ii; sodium sulphate, ounce iv. take two tablespoonsful of this in a glass of hot water before breakfast. should these not succeed, assist the action of the drugs by the use of enemata. the pill of aloin, strychnine sulphate, and extract of cascara, with the addition of a small quantity of hyoscyamus, is a mild tonic purgative. in cases of constipation with high tension, there is no drug as valuable as calomel or one of the other mercurials given occasionally. never give epsom salts unless copious watery stools are desired to deplete effusion into the serous cavities or into the subcutaneous tissue. chronic constipation increases the gravity of the prognosis. in case of suppression of urine and anasarca, hot air packs may be of value. the patient may be wrapped in a hot wet sheet and covered with blankets. i do not believe in administering pilocarpine to assist the sweating. remember to treat the patient and not the disease. the careful hygienic and dietetic treatment, combined with the least amount of drugging, is the best and most rational method of treatment. index a abdominal symptoms, 201 aconite in treatment, 242

endoscopy and laryngeal surgery. the abstract was prepared under the author's direction by a reader, in order to get a reader's point of view on the presentation of the subject in the earlier book. with this abstract as a starting point, the author has endeavored, so far as lay within his limited abilities, to accomplish the difficult task of presenting by written word the various purely manual endoscopic procedures. the large number of corrections and revisions found necessary has confirmed the wisdom of the plan of getting the reader's point of view; and these revisions, together with numerous additions, have brought the treatment of the subject up to date so far as is possible within the limits of a working manual. acknowledgment is due the personnel of the w. b. saunders company

bibliography 311 index 315 [17] chapter i--instrumentarium direct laryngoscopy, bronchoscopy, esophagoscopy and gastroscopy are procedures in which the lower air and food passages are inspected and treated by the aid of electrically lighted tubes which serve as specula to manipulate obstructing tissues out of the way and to bring others into the line of direct vision. illumination is supplied by a small tungsten-filamented, electric, "cold" lamp situated at the distal extremity of the instrument in a special groove which protects it from any possible injury during the introduction of instruments through the tube. the bronchi and the esophagus will not allow dilatation beyond their normal caliber; therefore, it is necessary to have tubes of the sizes to fit these passages at various developmental ages. rupture or even over-distention of a bronchus or of the thoracic esophagus is almost invariably fatal. the armamentarium of the endoscopist must be complete, for it is rarely possible to substitute, or to improvise makeshifts, while the bronchoscope is in situ. furthermore, the instruments must be of the proper model and well made; otherwise difficulties and dangers will attend attempts to see them. _laryngoscopes_.--the regular type of laryngoscope shown in fig. i (a, b, c) is made in adult's, child's, and infant's sizes. the instruments have a removable slide on the top of the tubular portion of the speculum to allow the removal of the laryngoscope after the insertion of the bronchoscope through it. the infant size is made in two forms, one with, the other without a removable slide; with either form the larynx of an infant can be exposed in but a few seconds and a definite diagnosis made, without anesthesia, general or local; a thing possible by no other method. for operative work on the larynx of adults, such as the removal of benign growths, particularly when these are situated in the anterior portion of the larynx, a special tubular laryngoscope having a heart-shaped lumen and a beveled tip is used. with this instrument the anterior commissure is readily exposed, and because of this it is named the anterior commissure laryngoscope (fig. 1, d). the tip of the anterior commissure laryngoscope can be used to expose either ventricle of the larynx by lifting the ventricular band, or it may be passed through the adult glottis for work in the subglottic region. this instrument may also be used as an esophageal speculum and as a pleuroscope. a side-slide laryngoscope, used with or without the slide, is occasionally useful. _bronchoscopes_.--the regular bronchoscope is a hollow brass tube slanted at its distal end, and having a handle at its proximal or ocular extremity. an auxiliary canal on its under surface contains the light carrier, the electric bulb of which is situated in a recess in the beveled distal end of the tube. numerous perforations in the distal part of the tube allow air to enter from other bronchi when the tube-mouth is inserted into one whose aerating function may be impaired. the accessory tube on the upper surface of the bronchoscope ends within the lumen of the bronchoscope, and is used for the insufflation of oxygen or anesthetics, (fig. 2, a, b, c, d). for certain work such as drainage of pulmonary abscesses, the lavage treatment of bronchiectasis and for foreign-body or other cases with abundant secretions, a drainage-bronchoscope is useful the drainage canal may be on top, or on the under surface next to the light-carrier canal. for ordinary work, however, secretion in the bronchus is best removed by sponge-pumping (q.v.) which at the same time cleans the lamp. the drainage bronchoscope may be used in any case in which the very slightly-greater area of cross section is no disadvantage; but in children the added bulk is usually objectionable, and in cases of recent foreign-body, secretions are not troublesome. as before mentioned, the lower air passages will not tolerate dilatation; therefore, it is necessary never to use tubes larger than the size of the passages to be examined. four sizes are sufficient for any possible case, from a newborn infant to the largest adult. for infants under one year, the proper tube is the 4 mm. by 30 cm.; the child's size, 5 mm. by 30 cm., is used for children aged from one to five years. for children six years or over, the 7 mm. by 40 cm. bronchoscope (the adolescent size) can be used unless the smaller bronchi are to be explored. the adult bronchoscope measures 9 mm. by 40 cm. the author occasionally uses special sizes, 5 mm. x 45 cm., 6 mm. x 35 cm., 8 mm. x 40 cm. _esophagoscopes_.-the esophagoscope, like the bronchoscope, is a hollow brass tube with beveled distal end containing a small electric light. it differs from the bronchoscope in that it has no perforations, and has a drainage canal on its upper surface, or next to the light-carrier canal which opens within the distal end of the tube. the exact size, position, and shape of the drainage outlets is important on bronchoscopes, and to an even greater degree on esophagoscopes. if the proximal edge of the drainage outlet is too near the distal end of the endoscopic tube, the mucosa will be drawn into the outlet, not only obstructing it, but, most important, traumatizing the mucosa. if, for instance, the esophagoscope were to be pushed upon with a fold thus anchored in the distal end, the esophageal wall could easily be torn. to admit the largest sizes of esophagoscopic bougies (fig. 40), special esophagoscopes (fig. 5) are made with both light canal and drainage canal outside the lumen of the tube, leaving the full area of luminal cross-section unencroached upon. they can, of course, be used for all purposes, but the slightly greater circumference is at times a disadvantage. the esophageal and stomach secretions are much thinner than bronchial secretions, and, if free from food, are readily aspirated through a comparatively small canal. if the canal becomes obstructed during esophagoscopy, the positive pressure tube of the aspirator is used to blow out the obstruction. two sizes of esophagoscopes are all that are required--7 mm. x 45 cm. for children, and 10 mm. x 53 cm. for adults (fig. 3, a and b); but various other sizes and lengths are used by the author for special purposes.* large esophagoscopes cause dangerous dyspnea in children. if, it is desired to balloon the esophagus with air, the window plug shown in fig. 6, is inserted into the proximal end of the esophagoscope, and air insufflated by means of the hand aspirator or with a hand bulb. the window can be replaced by a rubber diaphragm with a perforation for forceps if desired. it will be noted that none of the endoscopic tubes are fitted with mandrins. they are to be introduced under the direct guidance of the eye only. mandrins are obtainable, but their use is objectionable for a number of reasons, chief of which is the danger of overriding a foreign body or a lesion, or of perforating a lesion, or even the normal esophageal wall. the slanted end on the esophagoscope obviates the necessity of a mandrin for introduction. the longer the slant, with consequent acuting of the angle, the more the introduction is facilitated; but too acute an angle increases the risk of perforating the esophageal wall, and necessitates the utmost caution. in some foreign-body cases an acute angle giving a long slant is useful, in others a short slant is better, and in a few cases the squarely cut-off distal end is best. to have all of these different slants on hand would require too many tubes. therefore the author has settled upon a moderate angle for the end of both esophagoscopes and bronchoscopes that is easy to insert, and serves all purposes in the version and other manipulations required by the various mechanical problems of foreign-body extraction. he has, however, retained all the experimental models, for occasional use in such cases as he falls heir to because of a problem of extraordinary difficulty. * a 9 mm. x 45 cm. esophagoscope will reach the stomach of almost all adults and is somewhat easier to introduce than the 10 mm. x 53 cm., which may be omitted from the set if economy must be practiced. [fig. i.--author's laryngoscopes. these are the standard sizes and fulfill all requirements. many other forms have been devised by the author, but have been omitted from the list as unnecessary. the infant diagnostic laryngoscope (c) is not for introducing bronchoscopes, and is not absolutely necessary, as the larynx of any infant can be inspected with the child's size laryngoscope (b). a adult's size; b, child's size; c, infant's diagnostic size; d, anterior commissure laryngoscope; e, with drainage canal; 17, intubating laryngoscope, large lumen. all the laryngoscopes are preferred without drainage canals.] [fig. 2.--the author's bronchoscopes of the sizes regularly used. various other lengths and diameters are on hand for occasional use for special purposes. with the exception of a 6 mm. x 35 cm. size for older children, these special bronchoscopes are very rarely used and none of them can be regarded as necessary. for special purposes, however, special shapes of tube-mouth are useful, as, for instance, the oval end to facilitate the getting of both points of a staple into the tube-mouth the illustrated instruments are as follows: a, infant's size, 4 mm. x 30 cm.; b, child's size, 5 mm. x 30 cm.; c, adolescent's size, 7 mm. x 40 cm.; d, adult's size, 9 mm. x 40 cm.; e, aspirating bronchoscope made in all the foregoing sizes, and in a special size, 5 mm. x 45 cm.] [fig. 3.--the author's esophagoscopes of the sizes he has standardized for all ordinary requirements. he uses various other lengths and sizes for special purposes, but none of them are really necessary. a gastroscope, 10 mm. x 70 cm., is useful for adults, especially in cases of gastroptosis. drainage canals are placed at the top or at the side of the tube, next to the light-carrier canal. a, adult's size, 10 mm. x 53 cm.; b, child's size, 7 mm. x 45 cm.; c and d, full lumen, with both light canal and drainage canal outside the wall of the tube, to be used for passing very large bougies. this instrument is made in adult, child, and adolescent (8 mm. by 45 cm.) sizes. gastroscopes and esophagoscopes of the sizes given above (a) and (b), can be used also as gastroscopes. a small form of c, 5 mm. x 30 cm. is used in infants, and also as a retrograde esophagoscope in patients of any age. e, window plug for ballooning gastroscope, f.] [fig. 4.--author's short esophagoscopes and esophageal specula a, esophageal speculum and hypopharyngoscope, adult's size; b, esophageal speculum and hypopharyngoscope, child's size; c, heavy handled short esophagoscope; d, heavy handled short esophagoscope with drainage.] [fig. 5.--cross section of full-lumen esophagoscope for the use of largest bourgies. the canals for the light carrier and for drainage are so constructed that they do not encroach upon the lumen of the tube.] [25] the special sized esophagoscopes most often useful are the 8 mm. x 30 cm., the 8 mm. x 45 cm., and the 5 mm. x 45 cm. these are made with the drainage canal in various positions. for operations on the upper end of the esophagus, and particularly for foreign body work, the esophageal speculum shown at a and b, in fig. 4, is of the greatest service. with it, the anterior wall of the post-cricoidal pharynx is lifted forward, and the upper esophageal orifice exposed. it can then be inserted deeper, and the upper third of the esophagus can be explored. two sizes are made, the adult's and the child's size. these instruments serve, very efficiently as pleuroscopes. they are made with and without drainage canals, the latter being the more useful form. [fig. 6.--window-plug with glass cap interchangeable with a cap having a rubber diaphragm with a perforation so that forceps may be used without allowing air to escape. valves on the canals (e, f, fig. 3) are preferable.] _gastroscopes_.--the gastroscope is of the same construction as the esophagoscope, with the exception that it is made longer, in order to reach all parts of the stomach. in ordinary cases, the regular esophagoscopes for adults and children respectively will afford a good view of the stomach, but there are cases which require longer tubes, and for these a gastroscope 10 mm. x 70 cm. is made, and also one 10 mm. x 80 cm., though the latter has never been needed but once. [26] _pleuroscopes_.--as mentioned above the anterior commissure laryngoscope and the esophageal specula make very efficient pleuroscopes; but three different forms of pleuroscopes have been devised by the author for pleuroscopy. the retrograde esophagoscope serves very well for work through small fistulae. _measuring rule_ (fig. 7).--it is customary to locate esophageal lesions by denoting their distance from the incisor teeth. this is readily done by measuring the distance from the proximal end of the esophagoscope to the upper incisor teeth, or in their absence, to the upper alveolar process, and subtracting this measurement from the known length of the tube. thus, if an esophagoscope 45 cm. long be introduced and we find that the distance from the incisor teeth to the ocular end of the esophagoscope as measured by the rule is 20 cm., we subtract this 20 cm. from the total length of the esophagoscope (45 cm.) and then know that the distal end of the tube is 25 cm. from the incisor teeth. graduation marks on the tube have been used, but are objectionable. [fig. 7.--measuring rule for gauging in centimeters the depth of any location by subtraction of the length of the uninserted portion of the esophagoscope or bronchoscope. this is preferable to graduations marked on the tubes, though the tubes can be marked with a scale if desired.] _batteries_.--the simplest, best, and safest source of current is a double dry battery arranged in three groups of two cells each, connected in series (fig. 8). each set should have two binding posts and a rheostat. the binding posts should have double holes for two additional cords, to be kept in reserve for use in case a cord becomes defective.* the commercial current reduced through a rheostat should never be used, because there is always the possibility of "grounding" the circuit through the patient; a highly dangerous accident when we consider that the tube makes a long moist contact in tissues close to the course of both the vagi and the heart. the endoscopist should never depend upon a pocket battery as a source of illumination, for it is almost certain to fail during the endoscopy. the wires connecting the battery and endoscopic instrument are covered with rubber, so that they may be cleansed and superficially sterilized with alcohol. they may be totally immersed in alcohol for any length of time without injury. * when this is done care is necessary to avoid attempting to use simultaneously the two cords from one pair of posts. [fig 8.--the author's endoscopic battery, heavily built for reliability. it contains 6 dry cells, series-connected in 3 groups of 2 cells each. each group has its own rheostat and pair of binding posts.] _aspirating tubes_.--independent aspirating tubes involve delay in their use as compared to aspirating canals in the wall of the endoscopic tube; but there are special cases in which an independent tube is invaluable. three forms are used by the author. the "velvet eye" cannot traumatize the mucosa (fig. 9). to hold a foreign body by suction, a squarely cut off end is necessary. for use through the tracheotomic wound without a bronchoscope a malleable tube (fig. 10) is better. [fig. 9.--the author's protected-aperture endoscopic aspirating tube for aspiration of pharyngeal secretions during direct laryngoscopy and endotracheobronchial secretions at bronchoscopy, also for draining retropharyngeal abscesses. the laryngoscopes are obtainable with drainage canals, but for most purposes the independent aspirating tube shown above is more satisfactory. the tubes are made in 20 30, 40, and 60 cm. lengths. an aperture on both sides prevents drawing in the mucosa. it can be used for insufflation of ether if desired. an aspirating tube of the same design, but having a squarely cut off end, is sometimes useful for removing secretions lying close to a foreign body; for removing papillomata; and even for withdrawing foreign bodies of a soft surface consistency. it is not often that the foreign bodies can be thus withdrawn through the glottis, but closely fitting foreign bodies can at least be withdrawn to a higher level at which ample forceps spaces will permit application of forceps. such aspirating tubes, however, are not so safe to use as the protected, double aperture tubes.] [fig. 10.--the author's malleable tracheotomic aspirating tube for removal of secretions, exudates, crusts, etc., from the tracheobronchial tree through the tracheotomic wound without a bronchoscope. the tube is made of copper so that it can be bent to any curve, and the copper wire stylet prevents kinking. the stylet is removed before using the tube for aspiration.] [28] _aspirators_.--the various electric aspirators so universally used in throat operations should be utilized to withdraw secretions in the tubes fitted with drainage canals. they, however, have the disadvantages of not being easily transported, and of occasionally being out of order. the hand aspirator shown in fig. 11 is, therefore, a necessary part of the instrumental equipment. it never fails to work, is portable, and affords both positive and negative pressures. the positive pressure is sometimes useful in clearing the drainage canal of any particles of food, tissue, clots, or secretion which may obstruct it; and it also serves to fill the stomach or esophagus with air when the ballooning procedure is used. the mechanical aspirator (fig. 12) is highly efficient and is the one used in the bronchoscopic clinic. the positive pressure will quickly clear obstructed drainage canals, and may be used while the esophagoscope is in situ, by simply detaching the minus pressure tube and attaching the plus pressure. in the lungs, however, high plus pressures are so dangerous that the pressure valve must be lowered. [fig. 11--portable aspirator for endoscopy with additional tube connected with the plus pressure side for use in case of occlusion of the drainage canal. this aspirator has the advantage of great power with portability. where portability is not required the electrically operated aspirator is better.] [fig. 12.--robinson mechanical aspirator adapted for bronchoscopic and esophagoscopic aspiration by the author. the positive pressure is used for clearing obstructed drainage canals and tubes.] [fig. 13.--apparatus for insufflation of ether or chloroform during bronchoscopy, for those who may desire to use general anesthesia. the mechanical methods of intratracheal insufflation anesthesia subsequently developed by meltzer and auer, elsberg, geo. p. muller and others have rightly superseded this apparatus for all general surgical purposes.] _sponge-pumping_.--while the usually thin, watery esophageal and gastric secretions, if free from food, are readily aspirated through a drainage canal, the secretions of the bronchi are often thick and mucilaginous and aspirated with difficulty. further-more, bronchial secretions as a rule are not collected in pools, but are distributed over the walls of the larger bronchi and continuously well up from smaller bronchi during cough. the aspirating bronchoscopes should be used whenever their very slight additional area of cross-section is unobjectionable. in most cases, however, the most advantageous way to remove bronchial secretion has been found to be by introducing a gauze swab on a long sponge carrier (fig. 14), so that the sponge extends beyond the distal end of the bronchoscope, causing cough. then withdrawal of the sponge carrier will remove all of the secretion in the tube just as the plunger in a pump will lift all of the water above it. by this maneuver the walls of the bronchus are wiped free from secretions, and the lamp itself is cleansed. [fig. 14.--sponge carrier with long collar for carrying the small sponges shown in fig. 15. the collar screws down as in the coolidge cotton carrier. about a dozen of these are needed and they should all be small enough to go through the 4 mm. (diameter) bronchoscope and long enough to reach through the 53 cm. (length) esophagoscope, so that one set will do for all tubes. the schema shows method of sponging. the carrier c, armed with the sponge, s, when rotated as shown by the dart, d, wipes the field, p, at the same time wiping the lamp, l. the lamp does not need ever to be withdrawn for cleaning during bronchoscopy. it is protected in a recess so that it does not catch in the sponges.] [fig 15.--exact size to which the bandage-gauze is cut to make endoscopic sponges. each rectangle is the size for the tubal diameter given. the dimensions of the respective rectangles are not given because it is easier for the nurse or any one to cut a cardboard pattern of each size directly from this drawing. the gauze rectangles are folded up endwise as shown at a, then once in the middle as at b, then strung one dozen on a safety pin. in america gauze bandages run about 16 threads to the centimeter. different material might require a slightly different size and the pattern could be made to suit.] [32] the gauze sponges are made by the instrument nurse as directed in fig. 15, and are strung on safety pins, wrapped in paper, the size indicated by a figure on the wrapper, and then sterilized in an autoclave. the sterile packages are opened only as needed. these "bronchoscopic sponges" are also made by johnston and johnston, of new brunswick, n. j. and are sold in the shops. _mouth-gag_.--wide gagging prevents proper exposure of the larynx by forcing the mandible down on the hyoid bone. the mouth should be gently opened and a bite block (fig. 16) inserted between the teeth on the left side of the patient's mouth, to prevent closing of the jaws on the delicate bronchoscope or esophagoscope. [fig. 16.--bite block to be inserted between the teeth to prevent closure of the jaws on the endoscopic tube. this is the mckee-mccready modification of the boyce thimble with the omission of the etherizing tube, which is no longer needed. the block has been improved by dr. w. f. moore of the bronchoscopic clinic.] _forceps_.--delicacy of touch and manipulation are an absolute necessity if the endoscopist is to avoid mortality; therefore, heavily built and spring-opposed forceps are dangerous as well as useless. for foreign-body work in the larynx, and for the removal of benign laryngeal growths, the alligator forceps with roughened jaws shown in fig. 17 serve every purpose. [fig. 17.--laryngeal grasping forceps designed by mosher. for my own use i have taken off the ratchet-locking device for all general work, to be reapplied on the rare occasions when it is required.] _bronchoscopic and esophagoscopic grasping forceps_ are of the tubular type, that is, a stylet carrying the jaws works in a slender tube so that traction on the stylet draws the v of the open jaws into the lumen of the tube, thus causing the blades to approximate. they are very delicate and light, yet have great grasping power and will sustain any degree of traction that it is safe to exert. they permit of the delicacy of touch of a violin bow. the two types of jaws most frequently used, are those with the forward-grasping blades shown in fig. 18, and those having side-grasping blades shown in fig. 19. the side-curved forceps are perhaps the most generally useful of all the endoscopic forceps; the side projection of the jaws makes them readily visible during their closure on an object; their broader grasp is also an advantage., the projection of the blades in the side-curved grasping forceps should always be directed toward the left. if it is desired that they open in another direction this should be accomplished by turning the handle and not by adjusting the blade itself. if this rule be followed it will always be possible to tell by the position of the handle exactly where the blades are situated; whereas, if the jaws themselves are turned, confusion is sure to result. the forward-grasping forceps are always so adjusted that the jaws open in an up-and-down direction. on rare occasions it may be deemed desirable to turn the stylet of either forceps in some other direction relative to the handle. [fig. 18.--the author's forward grasping tube forceps. the handle mechanism is so simple and delicate that the most exquisite delicacy of touch is possible. two locknuts and a thumbscrew take up all lost motion yet afford perfect adjustability and easy separation for cleansing. at a is shown a small clip for keeping the jaws together to prevent injurious bending in the sterilizer, or carrying case. at the left is shown a handle-clamp for locking the forceps on a foreign body in the solution of certain rarely encountered mechanical problems. the jaws are serrated and cupped.] [fig. 19.--jaws of the author's side-curved endoscopic forceps. these work as shown in the preceding illustration, each forceps having its own handle and tube. originally the end of the cannula and stylet were squared to prevent rotation of the jaws in the cannula. this was found to be unnecessary with properly shaped jaws, which wedge tightly.] _rotation forceps_.--it is sometimes desired to make traction on an irregularly shaped foreign body, and yet to allow the object to turn into the line of least resistance while traction is being made. this can be accomplished by the use of the rotation forceps (fig. 20), which have for blades two pointed hooks that meet at their points and do not overlap. rotation forceps made on the model of the laryngeal grasping forceps, but having opposing points at the end of the blades, are sometimes very useful for the removal of irregular foreign bodies in the larynx, or when used through the esophageal speculum they are of great service in the extraction of such objects as bones, pin-buttons, and tooth-plates, from the upper esophagus. these forceps are termed laryngeal rotation forceps (fig. 31). all the various forms of forceps are made in a very delicate size often called the "mosquito" or "extra light" forceps, 40 cm. in length, for use in the 4 mm. and the 5 mm. bronchoscopes. for the 5 mm. bronchoscopes heavier forceps of the 40 cm. length are made. for the larger tubes the forceps are made in 45 cm., 50 cm., and 60 cm. lengths. a square-cannula forceps to prevent turning of the jaws was at one time used by the author but it has since been found that round cannula pattern serves all purposes. [fig. 20.--the author's rotation forceps. useful to allow turning of an irregular foreign body to a safer relation for withdrawal and for the esophagoscopic removal of safety pins by the method of pushing them into the stomach, turning and withdrawal, spring up.] _upper-lobe-bronchus forceps_.--foreign bodies rarely lodge in an upper-lobe bronchus, yet with such a problem it is necessary to have forceps that will reach around a corner. the upper-lobe-bronchus forceps shown in fig. 27 have curved jaws so made as to straighten out while passing through the bronchoscope and to spring back into their original shape on up from the lower jaw emerging from the distal end of the bronchoscopic tube, the radius of curvature being regulated by the extent of emergence permitted. they are made in extra-light pattern, 40 cm. long, and the regular model 45 cm. long. the full-curved model, giving 180 degrees and reaching up into the ascending branches, is made in both light and heavy patterns. forceps with less curve, and without the spiral, are used when it is desired to reach only a short distance "around the corner" anywhere in the bronchi. these are also useful, as suggested by willis f. manges, in dealing with safety pins in the esophagus or tracheobronchial tree. [fig. 21.--tucker jaws for the author's forceps. the tiny lip projecting down from the upper, and up from the lower jaw prevents sidewise escape of the shaft of a pin, tack, nail or needle. the shaft is automatically thrown parallel to the bronchoscopic axis. drawing about four times actual size.] [36] _tucker forceps_--gabriel tucker modified the regular side-curved forceps by adding a lip (fig. 21) to the left hand side of both upper and lower jaws. this prevents the shaft of a tack, nail, or pin, from springing out of the grasp of the jaws, and is so efficient that it has brought certainty of grasp never before obtainable. with it the solution of the safety-pin problem devised by the author many years ago has a facility and certainty of execution that makes it the method of choice in safety-pin extraction. [fig. 22.--the author's down-jaw esophageal forceps. the dropping jaw is useful for reaching backward below the cricopharyngeal fold when using the esophageal speculum in the removal of foreign bodies. posterior forceps-spaces are often scanty in cases of foreign bodies lodged just below the cricopharyngeus.] [fig. 23.--expansile forceps for the endoscopic removal of hollow foreign bodies such as intubation tubes, tracheal cannulae, caps, and cartridge shells.] _screw forceps_.--for the secure grasp of screws the jaws devised by dr. tucker for tacks and pins are excellent (fig. 21). _expanding forceps_.--hollow objects may require expanding forceps as shown in fig. 23. in using them it is necessary to be certain that the jaws are inside the hollow body before expanding them and making traction. otherwise severe, even fatal, trauma may be inflicted. [fig. 24.--the author's fenestrated peanut forceps. the delicate construction with long, springy and fenestrated jaws give in gentle hands a maximum security with a minimum of crushing tendency.] [fig. 25--the author's bronchial dilators, useful for dilating strictures above foreign bodies. the smaller size, shown at the right is also useful as an expanding forceps for removing intubation tubes, and other hollow objects. the larger size will go over the shaft of a tack.] [fig. 26.--the author's self-expanding bronchial dilator. the extent of expansion can be limited by the sense of touch or by an adjustable checking mechanism on the handle. the author frequently used smooth forceps for this purpose, and found them so efficient that this dilator was devised. the edges of forceps jaws are likely to scratch the epithelium. occasionally the instrument is useful in the esophagus; but it is not very safe, unless used with the utmost caution.] _tissue forceps_.--with the forceps illustrated in fig. 28 specimens of tissue may be removed for biopsy from the lower air and food passages with ease and certainty. they have a cross in the outer blade which holds the specimen removed. the action is very delicate, there being no springs, and the sense of touch imparted is often of great aid in the diagnosis. [fig. 27.--the author's upper-lobe bronchus forceps. at a is shown the full-curved form, for reaching into the ascending branches of the upper-lobe bronchus a number of different forms of jaws are made in this kind of forceps. only 2 are shown.] [fig 28--the author's endoscopic tissue forceps. the laryngeal length is 30 cm. for esophageal use they are made 50 and 60 cm. long. these are the best forceps for cutting out small specimens of tissue for biopsy.] the large basket punch forceps shown in fig. 33 are useful in removing larger growths or specimens of tissue from the pharynx or larynx. a portion or the whole of the epiglottis may be easily and quickly removed with these forceps, the laryngoscope introduced along the dorsum of the tongue into the glossoepiglottic recess, bringing the whole epiglottis into view. the forceps may be introduced through the laryngoscope or alongside the tube. in the latter method a greater lateral action of the forceps is obtainable, the tube being used for vision only. these forceps are 30 cm. long and are made in two sizes; one with the punch of the largest size that can be passed through the adult laryngoscope, and a smaller one for use through the anterior-commissure laryngoscope and the child's size laryngoscope. [fig. 29.--the author's papilloma forceps. the broad blunt nose will scalp off the growths without any injury to the normal basal tissues. voice-destroying and stenosing trauma are thus easily avoided.] [fig. 30.--the author's short mechanical spoon (30 cm. long).] _papilloma forceps_.--papillomata do not infiltrate; but superficial repullulations in many cases require repeated removals. if the basal tissues are traumatized, an impaired or ruined voice will result. the author designed these forceps (fig. 29) to scalp off the growths without injury to the normal tissues. [fig. 31.--the author's laryngeal rotation forceps.] [fig. 32.--enlarged view of the jaws of the author's vocal-nodule forceps. larger cups are made for other purposes but these tiny cups permit of that extreme delicacy required in the excision of the nodules from the vocal cords of singers and other voice users.] [fig 33.-extra large laryngeal tissue forceps. 30 cm. long, for removing entire growths or large specimens of tissue. a smaller size is made.] _bronchial dilators_.--it is not uncommon to find a stricture of the bronchus superjacent to a foreign body that has been in situ for a period of months. in order to remove the foreign body, this stricture must be dilated, and for this the bronchial dilator shown in fig. 25 was devised. the channel in each blade allows the closed dilator to be pushed down over the presenting point of such bodies as tacks, after which the blades are opened and the stricture stretched. a small and a large size are made. for enlarging the bronchial narrowing associated with pulmonary abscess and sometimes found above a bronchiectatic or foreign body cavity, the expanding dilator shown in fig. 26 is perhaps less apt to cause injury than ordinary forceps used in the same way. the stretching is here produced by the spring of the blades of the forceps and not by manual force. the closed blades are to be inserted through the strictured area, opened, and then slowly withdrawn. for cicatricial stenoses of the trachea the metallic bougies, fig. 40, are useful. for the larynx, those shown in fig. 41 are needed.

[fig 38.--half curved hook, 45 cm. and 60 cm. full curved patterns are made but caution is necessary to avoid them becoming anchored in the bronchi. spiral forms avoid this. the author makes for himself steel probe-pointed rods out of which he bends hooks of any desired shape. the rod is held in a pin-vise to facilitate bending of the point, after heating in an alcohol or bunsen flame.] _hooks_.--no hook greater than a right angle should be used through endoscopic tubes; for should it become caught in some of the smaller bronchi its extraction might result in serious trauma. the half curved hook shown in fig. 38 is the safest type; better still, a spiral twist to the hook will add to its uses, and by reversing the turning motion it may be "unscrewed" out if it becomes caught. hooks may easily be made from rods of malleable steel by heating the end in a spirit lamp and shaping the curve as desired by means of a pin-vise and pliers. about 2 cm. of the proximal end of the rod should be bent in exactly the opposite direction from that of the hook so as to form a handle which will tell the position of the hook by touch as well as by sight. coil-spring hooks for the upper-lobe-bronchus (fig. 39) will reach around the corner into the ascending bronchus of the upper-lobe-bronchus, but the utmost skill and care are required to make their use justifiable. [fig. 39.--author's coil-spring hook for the upper-lobe, bronchus] _safety-pin closer_.--there are a number of methods for the endoscopic removal of open safety-pins when the point is up, one of which is by closing the pin with the instrument shown in fig. 37 in the following manner. the oval ring is passed through the endoscope until it is beyond the spring of the safety-pin, the ring is then turned upward by depressing the handle, and by the aid of the prong the pin is pushed into the ring, which action approximates the point of the pin and the keeper and closes the pin. removal is then less difficult and without danger. this instrument may also be used as a mechanical spoon, in which case it may be passed to the side of a difficultly grasped foreign body, such as a pebble, the ring elevated and the object withdrawn. elsewhere will be found a description of the various safety-pin closers devised by various endoscopists. the author has used arrowsmith's closer with much satisfaction. _mechanical spoon_.--when soft, friable substances, such as a bolus of meat, become impacted in the upper esophagus, the short mechanical spoon (fig. 30) used through the esophageal speculum is of great aid in their removal. the blade in this instrument, as the name suggests, is a spoon and is not fenestrated as is the safety-pin closer, which if used for friable substances would allow them to slip through the fenestration. a longer form for use through bronchoscopes and esophagoscopes is shown in fig. 36. a laryngeal curette, cautery electrodes, cautery handle, and laryngeal knife are illustrated in fig. 34. the cautery is to be used with a transformer, or a storage battery. _spectacles_.--if the operator has no refractive error he will need two pairs of plane protective spectacles with very large "eyes." if ametropic, corrective lenses are necessary, and duplicate spectacles must be in charge of a nurse. for presbyopia two pairs of spectacles for 40 cm. distance and 65 cm. distance must be at hand. hook temple frames should be used so that they can be easily changed and adjusted by the nurse when the lenses become spattered. the spectacle nurse has ready at all times the extra spectacles, cleaned and warmed in a pan of heated water so that they will not be fogged by the patient's breath, and she changes them without delay as often as they become soiled. the operator should work with both eyes open and with his right eye at the tube mouth. the operating room should be somewhat darkened so as to facilitate the ignoring of the image in the left eye; any lighting should be at the operator's back, and should be insufficient to cause reflections from the inner surface of his glasses. [fig. 40.--the author's endoscopic bougies. the end consists of a flexible silk woven tip attached securely to a steel shank. sizes 8 to 30 french catheter scale. a metallic form of this bougie is useful in the trachea; but is not so safe for esophageal use.] [fig. 41.--the author's laryngeal bougie for the dilatation of cicatricial laryngeal stenosis. made in 10 sizes. the shaded triangle shows the cross-section at the widest part.] [fig. 42.--the author's bronchoscopic and esophagoscopic table.] [46] _endoscopic table_.--any operating table may be used, but the work is facilitated if a special table can be had which allows the placing of the patient in all required positions. the table illustrated in fig. 42 is so arranged that when the false top is drawn forward on the railroad, the head piece drops and the patient is placed in the correct (boyce) position for esophagoscopy or bronchoscopy, i.e., with the head and shoulders extending over the end of the table. by means of the wheel the plane of the table may be altered to any desired angle of inclination or height of head. _operating room_.--all endoscopic procedures should be performed in a somewhat darkened operating room where all the desired materials are at hand. an endoscopic team consists of three persons: the operator, the assistant who holds the head, and the instrument assistant. another person is required to hold the patient's arms and still another for the changing of the operator's glasses when they become spattered. the endoscopic team of three maintain surgical asepsis in the matter of hands and gowns, etc. the battery, on a small table of its own, is placed at the left hand of the operator. beyond it is the table for the mechanical aspirator, if one is used. all extra instruments are placed on a sterile table, within reach, but not in the way, while those instruments for use in the particular operation are placed on a small instrument table back of the endoscopist. only those instruments likely to be wanted should be placed on the working table, so that there shall be no confusion in their selection by the instrument nurse when called for. each moment of time should be utilized when the endoscopic procedure has been started, no time should be lost in the hunting or separating of instruments. to have the respective tables always in the same position relative to the operator prevents confusion and avoids delay. [fig 43.--the author's retrograde esophagoscope.] _oxygen tank and tracheotomy instruments_.--respiratory arrest may occur from shifting of a foreign body, pressure of the esophagoscope, tumor, or diverticulum full of food. rare as these contingencies are, it is essential that means for resuscitation be at hand. no endoscopic procedure should be undertaken without a set of tracheotomy instruments on the sterile table within instant reach. in respiratory arrest from the above mentioned causes, respiratory efforts are not apt to return unless oxygen and amyl nitrite are blown into the trachea either through a tracheotomy opening or better still by means of a bronchoscope introduced through the larynx. the limpness of the patient renders bronchoscopy so easy that the well-drilled bronchoscopist should have no difficulty in inserting a bronchoscope in 10 or 15 seconds, if proper preparedness has been observed. it is perhaps relatively rarely that such accidents occur, yet if preparations are made for such a contingency, a life may be saved which would otherwise be inevitably lost. the oxygen tank covered with a sterile muslin cover should stand to the left of the operating table. _asepsis_.--strict aseptic technic must be observed in all endoscopic procedures. the operator, first assistant, and instrument nurse must use the same precautions as to hand sterilization and sterile gowns as would be exercised in any surgical operation. the operator and first assistant should wear masks and sterile gloves. the patient is instructed to cleanse the mouth thoroughly with the tooth brush and a 20 per cent alcohol mouth wash. any dental defects should, if time permit, as in a course of repeated treatments, be remedied by the dental surgeon. when placed on the table with neck bare and the shoulders unhampered by clothing, the patient is covered with a sterile sheet and the head is enfolded in a sterile towel. the face is wiped with 70 per cent alcohol. it is to be remembered that while the patient is relatively immune to the bacteria he himself harbors, the implantation of different strains of perhaps the same type of organisms may prove virulent to him. furthermore the transference of lues, tuberculosis, diphtheria, pneumonia, erysipelas and other infective diseases would be inevitable if sterile precautions were not taken. all of the tubes and forceps are sterilized by boiling. the light-carriers and lamps may be sterilized by immersion in 95 per cent alcohol or by prolonged exposure to formaldehyde gas. continuous sterilization by keeping them put away in a metal box with formalin pastilles or other source of formaldehyde gas is an ideal method. knives and scissors are immersed in 95 per cent alcohol, and the rubber covered conducting cords are wiped with the same solution. _list of instruments_.--the following list has been compiled as a convenient basis for equipment, to which such special instruments as may be needed for special cases can be added from time to time. the instruments listed are of the author's design. 1 adult's laryngoscope. 1 child's laryngoscope. 1 infant's diagnostic laryngoscope. 1 anterior commissure laryngoscope. 1 bronchoscope, 4 mm. x 30 cm. 1 bronchoscope, 5 mm. x 30 cm. 1 bronchoscope, 7 mm. x 40 cm. 1 bronchoscope, 9 mm. x 40 cm. 1 esophagoscope, 7 mm. x 45 cm. 1 esophagoscope, 10 mm. x 53 cm. 1 esophagoscope, full lumen, 7 mm. x 45 cm. 1 esophagoscope, full lumen, 9 mm. x 45 cm. 1 esophageal speculum, adult. 1 esophageal speculum, child. 1 forward-grasping forceps, delicate, 40 cm. 1 forward-grasping forceps, regular, 50 cm. 1 forward-grasping forceps, regular, 60 cm. 1 side-grasping forceps, delicate, 40 cm. 1 side-grasping forceps, regular, 50 cm. 1 side-grasping forceps, regular, 60 cm. 1 rotation forceps, delicate, 40 cm. 1 rotation forceps, regular, 50 cm. 1 rotation forceps, regular, 60 cm. 1 laryngeal alligator forceps. 1 laryngeal papilloma forceps. 10 esophageal bougies, nos. 8 to 17 french (larger sizes to no. 36 may be added). 1 special measuring rule. 6 light sponge carriers. 1 aspirator with double tube for minus and plus pressure. 2 endoscopic aspirating tubes 30 and 50 cm. 1 half curved hook, 60 cm. 1 triple circuit bronchoscopy battery. 6 rubber covered conducting cords for battery. 1 box bronchoscopic sponges, size 4. 1 box bronchoscopic sponges, size 5. 1 box bronchoscopic sponges, size 7. 1 box bronchoscopic sponges, size 10. 1 bite block, 1 adult. 1 bite block, child. 2 dozen extra lamps for lighted instruments. 1 extra light carrier for each instrument.* 4 yards of pipe-cleaning, worsted-covered wire. [* messrs. george p. pilling and sons who are now making these instruments supply an extra light carrier and 2 extra lamps with each instrument.] _care of instruments_.--the endoscopist must either personally care for his instruments, or have an instrument nurse in his own employ, for if they are intrusted to the general operating room routine he will find that small parts will be lost; blades of forceps bent, broken, or rusted; tubes dinged; drainage canals choked with blood or secretions which have been coagulated by boiling, and electric attachments rendered unstable or unservicable, by boiling, etc. the tubes should be cleansed by forcing cold water through the drainage canals with the aspirating syringe, then dried by forcing pipe-cleaning worsted-covered wire through the light and drainage canals. gauze on a sponge carrier is used to clean the main canal. forceps stylets should be removed from their cannulae, and the cannulae cleansed with cold water, then dried and oiled with the pipe-cleaning material. the stylet should have any rough places smoothed with fine emery cloth and its blades carefully inspected; the parts are then oiled and reassembled. nickle plating on the tubes is apt to peel and these scales have sharp, cutting edges which may injure the mucosa. all tubes, therefore, should be unplated. rough places on the tubes should be smoothed with the finest emery cloth, or, better, on a buffing wheel. the dry cells in the battery should be renewed about every 4 months whether used or not. lamps, light carriers, and cords, after cleansing, are wiped with 95 per cent alcohol, and the light-carriers with the lamps in place are kept in a continuous sterilization box containing formaldehyde pastilles. it is of the utmost importance that instruments be always put away in perfect order. not only are cleaning and oiling imperative, but any needed repairs should be attended to at once. otherwise it will be inevitable that when gotten out in an emergency they will fail. in general surgery, a spoon will serve for a retractor and good work can be done with makeshifts; but in endoscopy, especially in the small, delicate, natural passages of children, the handicap of a defective or insufficient armamentarium may make all the difference between a success and a fatal failure. a bronchoscopic clinic should at all times be in the same state of preparedness for emergency as is everywhere required of a fire-engine house.

a fact easily demonstrated by the simple insertion of the direct laryngoscope and further demonstrated by the absence of dysphagia when the epiglottis is surgically removed, or is destroyed by ulceration. closure of the larynx is accomplished by the approximation of the ventricular bands, arytenoids and aryepiglottic folds, the latter having a sphincter-like action, and by the raising and tilting of the larynx. the _arytenoids_ form the upper posterior boundary of the larynx and our particular interest in them is directed toward their motility, for the rotation of the arytenoids at the cricoarytenoid articulations determines the movements of the cords and the production of voice. approximation of the arytenoids is a part of the mechanism of closure of the larynx. the _cricoid cartilage_ was regarded by esophagoscopists as the chief obstruction encountered on the introduction of the esophagoscope. as shown by the author, it is the cricopharyngeal fold, and the inconceivably powerful pull of the cricopharyngeal muscle on the cricoid cartilage, that causes the difficulty. the cricoid is pulled so powerfully back against the cervical spine, that it is hard to believe that this muscles is inserted into the median raphe and not into the spine itself (fig. 68). the _ventricular bands_ or false vocal cords vicariously phonate in the absence of the true cords, and assist in the protective function of the larynx. they form the floor of the _ventricles_ of the larynx, which are recesses on either side, between the false and true cords, and contain numerous mucous glands the secretion from which lubricates the cords. the ventricles are not visible by mirror laryngoscopy, but are readily exposed in their depths by lifting the respective ventricular bands with the tip of the laryngoscope. the _vocal cords_, which appear white, flat, and ribbon-like in the mirror, when viewed directly assume a reddish color, and reveal their true shelf-like formation. in the subglottic area the tissues are vascular, and, in children especially, they are prone to swell when traumatized, a fact which should be always in mind to emphasize the importance of gentleness in bronchoscopy, and furthermore, the necessity of avoiding this region in tracheotomy because of the danger of producing chronic laryngeal stenosis by the reaction of these tissues to the presence of the tracheotomic cannula. the _trachea_ just below its entrance into the thorax deviates slightly to the right, to allow room for the aorta. at the level of the second costal cartilage, the third in children, it bifurcates into the right and left main bronchi. posteriorly the bifurcation corresponds to about the fourth or fifth thoracic vertebra, the trachea being elastic, and displaced by various movements. the endoscopic appearance of the trachea is that of a tube flattened on its posterior wall. in two locations it normally often assumes a more or less oval outline; in the cervical region, due to pressure of the thyroid gland; and in the intrathoracic portion just above the bifurcation where it is crossed by the aorta. this latter flattening is rhythmically increased with each pulsation. under pathological conditions, the tracheal outline may be variously altered, even to obliteration of the lumen. the mucosa of the trachea and bronchi is moist and glistening, whitish in circular ridges corresponding to the cartilaginous rings, and reddish in the intervening grooves. the right bronchus is shorter, wider, and more nearly vertical than its fellow of the opposite side, and is practically the continuation of the trachea, while the left bronchus might be considered as a branch. the deviation of the right main bronchus is about 25 degrees, and its length unbranched in the adult is about 2.5 cm. the deviation of the left main bronchus is about 75 degrees and its adult length is about 5 cm. the right bronchus considered as a stem, may be said to give off three branches, the epiarterial, upperor superior-lobe bronchus; the middle-lobe bronchus; and the continuation downward, called the loweror inferior-lobe bronchus, which gives off dorsal, ventral and lateral branches. the left main bronchus gives off first the upper-or superior-lobe bronchus, the continuation being the lower-or inferior-lobe bronchus, consisting of a stem with dorsal, ventral and lateral branches. [fig. 44.--tracheo-bronchial tree. lm, left main bronchus; sl, superior lobe bronchus; ml, middle lobe bronchus; il, inferior lobe bronchus.] the septum between the right and left main bronchi, termed the carina, is situated to the left of the midtracheal line. it is recognized endoscopically as a short, shining ridge running sagitally, or, as the patient lies in the recumbent position, we speak of it as being vertical. on either side are seen the openings of the right and left main bronchi. in fig. 44, it will be seen that the lower border of the carina is on a level with the upper portion of the orifice of the right superior-lobe bronchus; with the carina as a landmark and by displacing with the bronchoscope the lateral wall of the right main bronchus, a second, smaller, vertical spur appears, and a view of the orifice of the right upper-lobe bronchus is obtained, though a lumen image cannot be presented. on passing down the right stem bronchus (patient recumbent) a horizontal partition or spur is found with the lumen of the middle-lobe bronchus extending toward the ventral surface of the body. all below this opening of the right middle-lobe bronchus constitutes the lower-lobe bronchus and its branches. [fig. 45.--bronchoscopic views. s; superior lobe bronchus; sl, superior lobe bronchus; i, inferior lobe bronchus; m, middle lobe bronchus.] [56] coming back to the carina and passing down the left bronchus, the relatively great distance from the carina to the upper-lobe bronchus is noted. the spur dividing the orifices of the left upperand lower-lobe bronchi is oblique in direction, and it is possible to see more of the lumen of the left upper-lobe bronchus than of its homologue on the right. below this are seen the lower-lobe bronchus and its divisions (fig. 45). _dimensions of the trachea and bronchi_.--it will be noted that the bronchi divide monopodially, not dichotomously. while the lumina of the individual bronchi diminish as the bronchi divide, the sum of the areas shows a progressive increase in total tubular area of cross-section. thus, the sum of the areas of cross-section of the two main bronchi, right and left, is greater than the area of cross section of the trachea. this follows the well known dynamic law. the relative increase in surface as the tubes branch and diminish in size increases the friction of the passing air, so that an actual increase in area of cross section is necessary, to avoid increasing resistance to the passage of air. the cadaveric dimensions of the tracheobronchial tree may be epitomized approximately as follows: adult male female child infant diameter trachea, 14 x 20 12 x 16 8 x 10 6 x 7 length trachea, cm. 12.0 10.0 6.0 4.0 length right bronchus 2.5 2.5 2.0 1.5 length left bronchus 5.0 5.0 3.0 2.5 length upper teeth to trachea 15.0 23.0 10.0 9.0 length total to secondary bronchus 32.0 28.0 19.0 15.0 in considering the foregoing table it is to be remembered that in life muscle tonus varies the lumen and on the whole renders it smaller. in the selection of tubes it must be remembered that the full diameter of the trachea is not available on account of the glottic aperture which in the adult is a triangle measuring approximately 12 x 22 x 22 mm. and permitting the passage of a tube not over 10 mm. in diameter without risk of injury. furthermore a tube which filled the trachea would be too large to enter either main bronchus. the normal movements of the trachea and bronchi are respiratory, pulsatory, bechic, and deglutitory. the two former are rhythmic while the two latter are intermittently noted during bronchoscopy. it is readily observed that the bronchi elongate and expand during inspiration while during expiration they shorten and contract. the bronchoscopist must learn to work in spite of the fact that the bronchi dilate, contract, elongate, shorten, kink, and are dinged and pushed this way and that. it is this resiliency and movability that make bronchoscopy possible. the inspiratory enlargement of lumen opens up the forceps spaces, and the facile bronchoscopist avails himself of the opportunity to seize the foreign body. the esophagus a few of the anatomical details must be kept especially in mind when it is desired to introduce straight and rigid instruments down the lumen of the gullet. first and most important is the fact that the esophageal walls are exceedingly thin and delicate and require the most careful manipulation. because of this delicacy of the walls and because the esophagus, being a constant passageway for bacteria from the mouth to the stomach, is never sterile, surgical procedures are associated with infective risks. for some other and not fully understood reason, the esophagus is, surgically speaking, one of the most intolerant of all human viscera. the anterior wall of the esophagus is in a part of its course, in close relation to the posterior wall of the trachea, and this portion is called the party wall. it is this party wall that contains the lymph drainage system of the posterior portion of the larynx, and it is largely by this route that posteriorly located malignant laryngeal neoplasms early metastasize to the mediastinum.

(1 in.) sixth cervical antero-posterior 17 mm. (3/4 in.) aortic transverse 24 mm. (1 in.) fourth thoracic antero-posterior 19 mm. (3/4 in.) left-bronchial transverse 23 mm. (1 in.) fifth thoracic antero-posterior 17 mm. (3/4 in.) diaphragmatic transverse 23 mm. (1 in+) tenth thoracic antero-posterior 23 mm. (in.--) for practical endoscopic purposes it is only necessary to remember that in a normal esophagus, straight and rigid tubes of 7 mm. diameter should pass freely in infants, and in adults, tubes of 10 mm. the 4 demonstrable constrictions from above downward are at 1. the crico-pharyngeal fold. 2. the crossing of the aorta. 3. the crossing of the left bronchus. 4. the hiatus esophageus. there is a definite fifth narrowing of the esophageal lumen not easily demonstrated esophagoscopically and not seen during dissection, but readily shown functionally by the fact that almost all foreign bodies lodge at this point. this narrowing occurs at the superior aperture of the thorax and is probably produced by the crowding of the numerous organs which enter or leave the thorax through this orifice. _the crico-pharyngeal constriction_, as already mentioned, is produced by the tonic contraction of a specialized band of the orbicular fibers of the lowermost portion of the inferior pharyngeal constrictor muscle, called the cricopharyngeal muscle. as shown by the author it is this muscle and not the cricoid cartilage alone that causes the difficulty in the insertion of an esophagoscope. this muscle is attached laterally to the edges of the signet of the cricoid which it pulls with an incomprehensible power against the posterior wall of the hypopharynx, thus closing the mouth of the esophagus. its other attachment is in the median posterior raphe. between these circular fibers (the cricopharyngeal muscle) and the oblique fibers of the inferior constrictor muscle there is a weakly supported point through which the esophageal wall may herniate to form the so-called pulsion diverticulum. it is at this weak point that fatal esophagoscopic perforation by inexperienced operators is most likely to occur. _the aortic narrowing_ of the esophagus may not be noticed at all if the patient is placed in the proper sequential "high-low" position. it is only when the tube-mouth is directed against the left anterior wall that the actively pulsating aorta is felt. the bronchial narrowing of the esophagus is due to backward displacement caused by the passage of the left bronchus over the anterior wall of the esophagus at about 27 cm. from the upper teeth in the adult. the ridge is quite prominent in some patients, especially those with dilatation from stenoses lower down. the hiatal narrowing is both anatomic and spasmodic. the peculiar arrangement of the tendinous and muscular structure of the diaphragm acts on this hiatal opening in a sphincter-like fashion. there are also special bundles of muscle fibers extending from the crura of the diaphragm and surrounding the esophagus, which contribute to tonic closure in the same way that a pinch-cock closes a rubber tube. the author has called the hiatal closure the "diaphragmatic pinchcock." _direction of the esophagus_.--the esophagus enters the chest in a decidedly backward as well as downward direction, parallel to that of the trachea, following the curves of the cervical and upper dorsal spine. below the left bronchus the esophagus turns forward, passing through the hiatus in the diaphragm anterior to and to the left of the aorta. the lower third of the esophagus in addition to its anterior curvature turns strongly to the left, so that an esophagoscope inserted from the right angle of the mouth, when introduced into the stomach, points in the direction of the anterior superior spine of the left ileum. it is necessary to keep this general course constantly in mind in all cases of esophagoscopy, but particularly in those cases in which there is marked dilatation of the esophagus following spasm at the diaphragm level. in such cases the aid of this knowledge of direction will greatly simplify the finding of the hiatus esophageus in the floor of the dilatation. the extrinsic or transmitted movements of the esophagus are respiratory and pulsatory, and to a slight extent, bechic. the respiratory movements consist in a dilatation or opening up of the thoracic esophageal lumen during inspiration, due to the negative intrathoracic pressure. the normal pulsatory movements are due to the pulsatile pressure of the aorta, found at the 4th thoracic vertebra (24 cm. from the upper teeth in the adult), and of the heart itself, most markedly felt at the level of the 7th and 8th thoracic vertebrae (about 30 cm. from the upper teeth in adults). as the distances of all the narrowings vary with age, it is useful to frame and hang up for reference a copy of the chart (fig. 46). the intrinsic movements of the esophagus are involuntary muscular contractions, as in deglutition and regurgitation; spasmodic, the latter usually having some pathologic cause; and tonic, as the normal hiatal closure, in the author's opinion may be considered. swallowing may be involuntary or voluntary. the constrictors are anatomically not considered part of esophagus proper. when the constrictors voluntarily deliver the bolus past the cricopharyngeal fold, the involuntary or peristaltic contractions of the esophageal mural musculature carry the bolus on downward. there is no sphincter at the cardiac end of the esophagus. the site of spasmodic stenosis in the lower third, the so-called cardiospasm, was first demonstrated by the author to be located at the hiatus esophageus and the spasmodic contractions are of the specialized muscle fibers there encircling the esophagus, and might be termed "phrenospasm," or "hiatal esophagismus." regurgitation of food from the stomach is normally prevented by the hiatal muscular diaphragmatic closure (called by the author the "diaphragmatic pinchcock") plus the kinking of the abdominal esophagus. in the author's opinion there is no spasm in the disease called "cardiospasm." it is simply the failure of the diaphragmatic pinchcock to open normally in the deglutitory cycle. a better name is functional hiatal stenosis. at retrograde esophagoscopy the cardia and abdominal esophagus do not seem to exist. the top of the stomach seems to be closed by the diaphragmatic pinchcock in the same way that the top of a bag is closed by a puckering string. [63] chapter iii--preparation of the patient for peroral endoscopy the suggestions of the author in the earlier volumes in regard to preparation of the patient, as for any operation, by a bath, laxative, etc., and especially by special cleansing of the mouth with 25 per cent alcohol, have received general endorsement. care should be taken not to set up undue reaction by vigorous scrubbing of gums unaccustomed to it. artificial dentures should be removed. even if no anesthetic is to be used, the patient should be fasted for five hours if possible, even for direct laryngoscopy in order to forestall vomiting. except in emergency cases every patient should be gone over by an internist for organic disease in any form. if an endolaryngeal operation is needed by a nephritic, preparatory treatment may prevent laryngeal edema or other complications. hemophilia should be thought of. it is quite common for the first symptom of an aortic aneurysm to be an impaired power to swallow, or the lodgment of a bolus of meat or other foreign body. if aneurysm is present and esophagoscopy is necessary, as it always is in foreign body cases, "to be fore-warned is to be forearmed." pulmonary tuberculosis is often unsuspected in very young children. there is great danger from tracheal pressure by an esophageal diverticulum or dilatation distended with food; or the food maybe regurgitated and aspirated into the larynx and trachea. therefore, in all esophageal cases the esophagus should be emptied by regurgitation induced by titillating the fauces with the finger after swallowing a tumblerful of water, pressure on the neck, etc. aspiration will succeed in some cases. in others it is absolutely necessary to remove food with the esophagoscope. if the aspirating tube becomes clogged by solid food, the method of swab aspiration mentioned under bronchoscopy will succeed. of course there is usually no cough to aid, but the involuntary abdominal and thoracic compression helps. should a patient arrive in a serious state of water-hunger, as part of the preparation the patient must be given water by hypodermoclysis and enteroclysis, and if necessary the endoscopy, except in dyspneic cases, must be delayed until the danger of water-starvation is past. as pointed out by ellen j. patterson the size of the thymus gland should be studied before an esophagoscopy is done on a child. every patient should be examined by indirect, mirror laryngoscopy as a preliminary to peroral endoscopy for any purpose whatsoever. this becomes doubly necessary in cases that are to be anesthetized. [65] chapter iv--anesthesia for peroral endoscopy a dyspneic patient should never be given a general anesthetic. cocaine should not be used on children under ten years of age because of its extreme toxicity. to these two postulates always in mind, a third one, applicable to both general and local anesthesia, is to be added--total abolition of the cough-reflex should be for short periods only. general anesthesia is never used in the bronchoscopic clinic for endoscopic procedures. the choice for each operator must, however, be a matter for individual decision, and will depend upon the personal equation, and degree of skill of the operator, and his ability to quiet the apprehensions of the patient. in other words, the operator must decide what is best for his particular patient under the conditions then existing. _children_ in the bronchoscopic clinic receive neither local nor general anesthesia, nor sedative, for laryngoscopic operations or esophagoscopy. bronchoscopy in the older children when no dyspnea is present has in recent years, at the suggestion of prof. hare, been preceded by a full dose of morphin sulphate (i.e., 1/8 grain for a child of six years) or a full physiologic dose of sodium bromide. the apprehension is thus somewhat allayed and the excessive cough-reflex quieted. the morphine should be given not less than an hour and a half before bronchoscopy to allow time for the onset of the soporific and antispasmodic effects which are the desiderata, not the analgesic effects. dosage is more dependent on temperament than on age or body weight. atropine is advantageously added to morphine in bronchoscopy for foreign bodies, not only for the usual reasons but for its effect as an antispasmodic, and especially for its diminution of endobronchial secretions. true, it does not diminish pus, but by diminishing the outpouring of normal secretions that dilute the pus the total quantity of fluid encountered is less than it otherwise would be. in cases of large quantities of pus, as in pulmonary abscess and bronchiectasis, however, no diminution is noticeable. no food or water is allowed for 5 hours prior to any endoscopic procedure, whether sedatives or anesthetics are to be given or not. if the stomach is not empty vomiting from contact of the tube in the pharynx will interfere with work. with _adults_ no anesthesia, general or local, is given for esophagoscopy. for laryngeal operation and bronchoscopy the following technic is used: one hour before operation the patient is given hypodermatically a full physiologic dose of morphin sulphate (from 1/4, to 3/8 gr.) guarded with atropin sulphate (gr. 1/150). care must be taken that the injection be not given into a vein. on the operating table the epiglottis and pharynx are painted with 10 per cent solution of cocain. two applications are usually sufficient completely to anesthetize the exterior and interior of the larynx by blocking of the superior laryngeal nerve without any endolaryngeal applications. the laryngoscope is now introduced and if found necessary a 20 per cent cocain solution is applied to the interior of the larynx and subglottic region, by means of gauze swabs fastened to the sponge carriers. here also two applications are quite sufficient to produce complete anesthesia in the larynx. if bronchoscopy is to be done the gauze swab is carried down through the exposed glottis to the carina, thus anesthetizing the tracheal mucosa. if further anesthetization of the bronchial mucosa is required, cocain may be applied in the same manner through the bronchoscope. in all these local applications prolonged contact of the swab is much more efficient than simply painting the surface. [67] in cases in which cocain is deemed contraindicated morphin alone is used. if given in sufficient dosage cocain can be altogether dispensed with in any case. it is perhaps _safer for the beginner_ in his early cases of esophagoscopy to have the patient relaxed by an ether anesthesia, provided the patient is not dyspneic to begin with, or made so by faulty position or by pressure of the esophagoscopic tube mouth on the tracheoesophageal "party wall." as proficiency develops, however, he will find anesthesia unnecessary. local anesthesia is needless for esophagoscopy, and if used at all should be limited to the laryngopharynx and never applied to the esophagus, for the esophagus is without sensation, as anyone may observe in drinking hot liquids. _direct laryngoscopy in children_ requires neither local nor general anesthesia, either for diagnosis or for removal of foreign bodies or growths from the larynx. general anesthesia is contraindicated because of the dyspnea apt to be present, and because the struggles of the patient might cause a dislodgment of the laryngeal intruder and aspiration to a lower level. the latter accident is also prone to follow attempts to cocainize the larynx. _technic for general anesthesia_.--for esophagoscopy and gastroscopy, if general anesthesia is desired, ether may be started by the usual method and continued by dropping upon folded gauze laid over the mouth after the tube is introduced. endo-tracheal administration of ether is, however, far safer than peroral administration, for it overcomes the danger of respiratory arrest from pressure of the esophagoscope, foreign body, or both, on the trachea. chloroform should not be used for esophagoscopy or gastroscopy because of its depressant action on the respiratory center. for bronchoscopy, ether or chloroform may be started in the usual way and continued by insufflating through the branch tube of the bronchoscope by means of the apparatus shown in fig. 13. in case of paralysis of the larynx, even if only monolateral, a general anesthetic if needed should be given by intratracheal insufflation. if the apparatus for this is not available the patient should be tracheotomized. hence, every adult patient should be examined with a throat mirror before general anesthesia for any purpose, and the necessity becomes doubly imperative before goiter operations. a number of fatalities have occurred from neglect of this precaution. _anesthetizing a tracheotomized patient_ is free from danger so long as the cannula is kept free from secretion. ether is dropped on gauze laid over the tracheotomic cannula and the anesthesia watched in the usual manner. if the laryngeal stenosis is not complete, ether-saturated gauze is to be placed over the mouth as well as over the tracheotomy tube. _endo-tracheal anesthesia_ is by far the safest way for the administration of ether for any purpose. by means of the silk-woven catheter introduced into the trachea, ether-laden air from an insufflation apparatus is piped down to the lungs continuously, and the strong return-flow prevents blood and secretions from entering the lower air-passages. the catheter should be of a size, relative to that of the glottic chink, to permit a free return-flow. a number 24 french is readily accommodated by the adult larynx and lies well out of the way along the posterior wall of the larynx. because of the little room occupied by the insufflation catheter this method affords ideal anesthesia for external laryngeal operations. operations on the nose, accessory sinuses and the pharynx, apt to be attended by considerable bleeding, are rendered free from the danger of aspiration pneumonia by endotracheal anesthesia. it is the safest anesthesia for goiter operations. endo-tracheal anesthesia has rendered needless the intricate negative pressure chamber formerly required for thoracic surgery, for by proper regulation of the pressure under which the ether ladened air is delivered, a lung may be held in any desired degree of expansion when the pleural cavity is opened. it is indicated in operations of the head, neck, or thorax, in which there is danger of respiratory arrest by centric inhibition or peripheral pressure; in operations in which there is a possibility of excessive bleeding and aspiration of blood or secretions; and in operations where it is desired to keep the anesthetist away from the operating field. various forms of apparatus for the delivery of the ether-laden vapor are supplied by instrument makers with explicit directions as to their mechanical management. we are concerned here mainly with the technic of the insertion of the intratracheal tube. the larynx should be examined with the mirror, preferably before the day of operation, for evidence of disease, and incidentally to determine the size of the catheter to be introduced, though the latter can be determined after the larynx is laryngoscopically exposed. the following list of rules for the introduction of the catheter will be of service (see fig. 59). rules for insertion of the catheter for insufflation anesthesia 1. the patient should be fully under the anesthetic by the open method so as to get full relaxation of the muscles of the neck. 2. the patient's head must be in full extension with the vertex firmly pushed down toward the feet of the patient, so as to throw the neck upward and bring the occiput down as close as possible beneath the cervical vertebrae. 3. no gag should be used, because the patient should be sufficiently anesthetized not to need a gag, and because wide gagging defeats the exposure of the larynx by jamming down the mandible. 4. the epiglottis must be identified before it is passed. 5. the speculum must pass sufficiently far below the tip of the epiglottis so that the latter will not slip. 6. too deep insertion must be avoided, as in this case the speculum goes posterior to the cricoid, and the cricoid is lifted, exposing the mouth of the esophagus, which is bewildering until sufficient education of the eye enables the operator to recognize the landmarks. 7. the patient's head is lifted off the table by the spatular tip of the laryngoscope. actual lifting of the head will not be necessary if the patient is fully relaxed; but the idea of lifting conveys the proper conception of laryngeal exposure (fig. 55). [71] chapter v--bronchoscopic oxygen insufflation bronchoscopic oxygen insufflation is a life-saving measure equalled by no other method known to the science of medicine, in all cases of asphyxia, or apnea, present or impending. its especial sphere of usefulness is in severe cases of electric shock, hanging, smoke asphyxia, strangulation, suffocation, thoracic or abdominal pressure, apnea, acute traumatic pneumothorax, respiratory arrest from absence of sufficient oxygen, or apnea from the presence of quantities of irrespirable or irritant gases. combined with bronchoscopic aspiration of secretions it is the best method of treatment for poisoning by chlorine gas, asphyxiating, and other war gases. bronchoscopic oxygen insufflation should be taught to every interne in every hospital. the emergency or accident ward of every hospital should have the necessary equipment and an interne familiar with its use. the method is simple, once the knack is acquired. the patient being limp and recumbent on a table, the larynx is exposed with the laryngoscope, and the bronchoscope is inserted as hereinafter described. the oxygen is turned on at the tank and the flow regulated before the rubber tube from the wash-bottle of tank is attached to the side-outlet of the bronchoscope. it is necessary to be certain that the flow is gentle, so that, with a free return flow the introduced pressure does not exceed the capillary pressure; otherwise the blood will be forced out of the capillaries and the ischemia of the lungs will be fatal. another danger is that overdistension causes inhibition of inspiration resulting in apnea continuing as long as the distension is maintained, if not longer. the return flow from the bronchoscope should be interrupted for 2 or 3 seconds several times a minute to inflate the lungs, but the flow must not be occluded longer than 3 seconds, because the intrapulmonary pressure would rise. a pearl of amyl nitrite may be broken in the wash bottle. slow rhythmic artificial respiratory movements are a useful adjunct, and unless the operator is very skillful in gauging the alternate pressures and releases with the thumb according to the oxygen pressure, it is vitally necessary to fill and deflate the lungs rhythmically by one of the well known methods of artificial respiration. anyone skilled in the introduction of the bronchoscope can do bronchoscopy in a few seconds, and it is especially easy in cases of respiratory arrest, because of the limp condition of the patient. the foregoing applies to cases in which a pulmotor would be used, such as apnea from electric shocks, etc. for obstructive dyspnea and asphyxia, tracheotomy is the procedure of choice, and the skillful tracheotomist would be justified in preferring tracheotomy for the other class of cases, insufflating the oxygen and amyl nitrite through the tracheotomic wound. the pulmotor and similar mechanisms are, perhaps, the best things the use of which can be taught to laymen; but as compared to bronchoscopic oxygen insufflation they are woefully inefficient, because the intraoral pressure forces the tongue back over the laryngeal orifice, obstructing the airway in this "death zone." by the introduction of the bronchoscope this death zone is entirely eliminated, and a free airway established for piping the oxygen directly into the lungs. [73] chapter vi--position of the patient for peroral endoscopy it is the author's invariable practice to place the patient in the dorsally recumbent position. the sitting position is less favorable. while lying on a well-padded, flat table the patient is readily controlled, the head is freely movable, secretions can be easily removed, the view obtained by the endoscopist is truly direct (without reversal of sides), and, most important, the employment of one position only favors smoother and more efficient team work, and a better endoscopic technic. _general principles of position_.--as will be seen in fig. 47 the trachea and esophagus are not horizontal in the thorax, but their long axes follow the curves of the cervical and dorsal spine. therefore, if we are to bring the buccal cavity and pharynx in a straight line with the trachea and esophagus it will be found necessary to elevate the whole head above the plane of the table, and at the same time make extension at the occipito-atloid joint. by this maneuver the cervical spine is brought in line with the upper portion of the dorsal spine as shown in fig. 55. it was formerly taught, and often in spite of my better knowledge i am still unconsciously prone to allow the head and cervical spine to assume a lower position than the plane of the table, the so-called rose position. with the head so placed, it is impossible to enter the lower air or food passages with a rigid tube, as will be shown by a study of the radiograph shown in fig. 49. extension of the head on the occipito-atloid joint is for the purpose of freeing the tube from the teeth, and the amount required will vary with the degree to which the mouth can be opened. whether the head be extended, flexed, or kept mid-way, the fundamental principle in the introduction of all endoscopic tubes is the anterior placing of the cervical spine and the high elevation of the head. the esophagus, just behind the heart, turns ventrally and to the left. in order to pass a rigid tube through this ventral curve the dorsal spine is now extended by lowering the head and shoulders below the plane of the table. this will be further explained in the chapter on esophagoscopy. in all of these procedures, the nose of the patient should be directed toward the zenith, and the assistant should _prevent rotation of the head_ as well as _prevent lowering of the head_. the patient should be urged as follows: "don't hold yourself so rigid." "let your head and neck go loose." "let your head rest in my hand." "don't try to hold it." "let me hold it." "relax." "don't raise your chest." [fig. 47.--schematic illustration of normal position of the intra-thoracic trachea and esophagus and also of the entire trachea when the patient is in the correct position for peroral bronchoscopy. when the head is thrown backward (as in the rose position) the anterior convexity of the cervical spine is transmitted to the trachea and esophagus and their axes deviated. the anterior deviation of the lower third of the esophagus shows the anatomical basis for the "high low" position for esophagoscopy] [fig. 48.--correct position of the cervical spine for esophagoscopy and bronchoscopy. (_illustration reproduced from author's article jour. am. med. assoc., sept. 25, 1909_)] [fig. 49.--curved position of the cervical spine, with anterior convexity, in the rose position, rendering esophagoscopy and bronchoscopy difficult or impossible. the devious course of the pharynx, larynx and trachea are plainly visible. the extension is incorrectly imparted to the whole cervical spine instead of only to the occipito-atloid joint. this is the usual and very faulty conception of the extended position. (_illustration reproduced from author's article, jour. am. med. assoc., sept. 25, 1909._)] [76] for _direct laryngoscopy_ the patient's head is raised above the plane of the table by the first assistant, who stands to the right of the patient, holding the bite block on his right thumb inserted in the left corner of the patient's mouth, while his extended right hand lies along the left side of the patient's cheek and head, and prevents rotation. his left hand, placed under the patient's occiput, elevates the head and maintains the desired degree of extension at the occipito-atloid joint (fig. 50). [fig 50.--direct laryngoscopy, recumbent patient. the second assistant is sitting holding the head in the boyce position, his left forearm on his left thigh his left foot on a stool whose top is 65 cm. lower than the table-top. his left hand is on the patient's sterile-covered scalp, the thumb on the forehead, the fingers under the occiput, making forced extension. the right forearm passes under the neck of the patient, so that the index finger of the right hand holds the bite-block in the left corner of the patient's mouth. the fingers of the operator's right hand pulls the upper lip out of all danger of getting pinched between the teeth and the laryngoscope. this is a precaution of the utmost importance and the trained habit of doing it must be developed by the peroral endoscopist.] _position for bronchoscopy and esophagoscopy_.--the dorsally recumbent patient is so placed that the head and shoulders extend beyond the table, the edge of which supports the thorax at about the level of the scapulae. during introduction, the head must be maintained in the same relative position to the table as that described for direct laryngoscopy, that is, elevated and extended. the first assistant, in this case, sits on a stool to the right of the patient's head, his left foot resting on a box about 14 inches in height, the left knee supporting the assistant's left hand, which being placed under the occiput of the patient maintains elevation and extension. the right arm of the assistant passes under the neck of the patient, the bite block being carried on the middle finger of the right hand and inserted into the left side of the patient's mouth. the right hand also prevents rotation of the head (fig. 51). as the bronchoscope or esophagoscope is further inserted, the head must be placed so that the tube corresponds to the axis of the lumen of the passage to be examined. if the left bronchus is being explored, the head must be brought strongly to the right. if the right middle lobe bronchus is being searched, the head would require some left lateral deflection and a considerable degree of lowering, for this bronchus, as before mentioned, extends anteriorly. during esophagoscopy when the level of the heart is reached, the head and upper thorax must be strongly depressed below the plane of the table in order to follow the axis of the lumen of the ventrally turning esophagus; at the same time the head must be brought somewhat to the right, since the esophagus in this region deviates strongly to the left. [fig. 51.--position of patient and assistant for introduction of the bronchoscope and esophagoscope. the middle of the scapulae rest on the edge of the table; the head and shoulders, free to move, are supported by the assistant, whose right arm passes under the neck; the right middle finger inserts the bite block into the left side of the mouth. the left hand, resting on the left knee maintains the desired degree of elevation, extension and lateral deflection required by the operator. the patient's vertex should be 10 cm. higher than the level of the top of the table. this is the boyce position, which has never been improved upon for bronchoscopy and esophagoscopy.] [fig. 52.--schema of position for endoscopy. a. normal recumbency on the table with pillow supporting the head. the larynx can be directly examined in this position, but a better position is obtainable. b. head is raised to proper position with head flexed. muscles of front of neck are relaxed and exposure of larynx thus rendered easier; but, for most endoscopic work, a certain amount of extension is desired. the elevation is the important thing. c. the neck being maintained in position b, the desired amount of extension of the head is obtained by a movement limited to the occipito-atloid articulation by the assistant's hand placed as shown by the dart (b). d. faulty position. unless prevented, almost all patients will heave up the chest and arch the lumbar spine so as to defeat the object and to render endoscopy difficult by bringing the chest up to the high-held head, thus assuming the same relation of the head to the chest as exists in the rose position (a faulty one for endoscopy) as will be understood by assuming that the dotted line, e, represents the table. if the pelvis be not held down to the table the patient may even assume the opisthotonous position by supporting his weight on his heels on the table and his head on the assistant's hand.] in obtaining the position of high head with occipito-atloid extension, the easiest and most certain method, as pointed out to me by my assistant, gabriel tucker, is first to raise the head, strongly flexed, as shown in fig. 52; then while maintaining it there, make the occipito-atloid extension. this has proven better than to elevate and extend in a combined simultaneous movement. if the patient would relax to limpness exposure of the larynx would be easily obtained, simply by lifting the head with the lip of the laryngoscope passed below the tip of the epiglottis (as in fig. 55) and no holding of the head would be necessary. but only rarely is a patient found who can do this. this degree of relaxation is of course, present in profound general ether anesthesia, which is not to be thought of for direct laryngoscopy, except when it is used for the purpose of insertion of intratracheal insufflation anesthetic tubes. for this, of course, the patient is already to be deeply anesthetized. the muscular tension exerted by some patients in assuming and holding a faulty position is almost as much of a hindrance to peroral endoscopy as is the position itself. the tendency of the patient to heave up his chest and assume a false position simulating the opisthotonous position (fig. 52) must be overcome by persuasion. this position has all the disadvantages of the rose position for endoscopy. [fig. 53.--the author's position for the removal of foreign bodies from the larynx or from any of the upper air or food passages. if dislodged, the intruder will not be aided by gravity to reach a deeper lodgement.] the one exception to these general positions is found in procedures for the removal of foreign bodies from the larynx. in such cases, while the same relative position of the head to the plane of the table is maintained, the whole table top is so inclined as to elevate the feet and lower the head, known as jackson's position. this semi-inversion of the patient allows the foreign body to drop into the pharynx if it should be dislodged, or slip from the forceps (fig. 53). [82] chapter vii--direct laryngoscopy _importance of mirror examination of the larynx_.--the presence of the direct laryngoscope incites spasmodic laryngeal reflexes, and the traction exerted somewhat distorts the tissues, so that accurate observations of variations in laryngeal mobility are difficult to obtain. the function of the laryngeal muscles and structures, therefore, can best be studied with the laryngeal mirror, except in infants and small children who will not tolerate the procedure of indirect laryngoscopy. a true idea of the depth of the larynx is not obtained with the mirror, and a view of the ventricles is rarely had. with the introduction of the direct laryngoscope it is found that the larynx is funnel shaped, and that the adult cords are situated about 3 cm. below the aryepiglottic folds; the cords also assume their true shelf-like character and take on a pinkish or yellowish tinge, rather than the pearly white seen in the mirror. they are not to any extent differentiated by color from the neighboring structures. their recognition depends almost wholly on form, position and movement. accurate observation is stimulated in all pathologic cases by making colored crayon sketches, however crude, of the mirror image of the larynx. the location of a growth may be thus graphically recorded, so that at the time of operation a glance will serve to refresh the memory as to its site. it is to be constantly kept in mind, however, that in the mirror image the sides are reversed because of the facing positions of the examiner and patient. direct laryngoscopy is the only method by which the larynx of children can be seen. the procedure need require less than a minute of time, and an accurate diagnosis of the condition present, whether papilloma, foreign body, diphtheria, paralysis, etc., may be thus obtained. the posterior pharyngeal wall should be examined in all dyspneic children for the possible existence of retropharyngeal abscess. [plate ii--direct and indirect laryngeal views from author's oil-color drawings from life: 1, epiglottis of child as seen by direct laryngoscopy in the recumbent position. 2, normal larynx spasmodically closed, as is usual on first exposure without anesthesia. 3, same on inspiration. 4, supraglottic papillomata as seen on direct laryngoscopy in a child of two years. 5, cyst of the larynx in a child of four years, seen on direct laryngoscopy without anesthesia. 6, indirect view of larynx eight weeks after thyrotomy for cancer of the right cord in a man of fifty years. 7, same after two years. an adventitious band indistinguishable from the original one has replaced the lost cord. 8, condition of the larynx three years after hemilaryngectomy for epithelioma in a patient fifty-one years of age. thyrotomy revealed such extensive involvement, with an open ulceration which had reached the perichondrium, that the entire left wing of the thyroid cartilage was removed with the left arytenoid. a sufficiently wide removal was accomplished without removing any part of the esophageal wall below the level of the crico-arytenoid joint. there is no attempt on the part of nature to form an adventitious cord on the left side. the normal arytenoid drew the normal cord over, approximately to the edge of the cicatricial tissue of the operated side. the voice, at first a very hoarse whisper, eventually was fairly loud, though slightly husky and inflexible. 9, the pharynx seen one year after laryngectomy for endothelioma in a man aged sixty-eight years. the purple papilla; anteriorly are at the base of the tongue, and from this the mucosa slopes downward and backward smoothly into the esophagus. there are some slight folds toward the left and some of these are quite cicatricial. the epiglottis was removed at operation. the trachea was sutured to the skin and did not communicate with the pharynx. (direct view.)] _contraindications to direct laryngoscopy_.--there are no absolute contraindications to direct laryngoscopy in any case where direct laryngoscopy is really needed for diagnosis or treatment. in extremely dyspneic patients, if the operator is not confident in his ability for a prompt and sure introduction of a bronchoscope, it may be wise to do a tracheotomy first. _instructions to the patient_.--before beginning endoscopy the patient should be told that he will feel a very disagreeable pressure on his neck and that he may feel as though he were about to choke. he must be gently but positively made to understand (1) that while the procedure is alarming, it is absolutely free from danger; (2) that you know just how it feels; (3) that you will not allow his breath to be shut off completely; (4) that he can help you and himself very much by paying close attention to breathing deeply and regularly; (5) and that he must not draw himself up rigidly as though "walking on ice," but must be easy and relaxed. _direct laryngoscopy. adult patient_.--before starting, every detail in regard to instrumental equipment and operating room assistants, (including an assistant to hold the arms and legs of the patient) must be complete. preparation of the patient and the technic of local anesthesia have been discussed in their respective chapters. the dorsally recumbent patient is draped with (not pinned in) a sterile sheet. the head, covered by sterile towels, is elevated, and slight extension is made at the occipitoatloid joint by the left hand of the first assistant. the bite block placed on the assistant's right thumb is inserted into the left angle of the patient's open mouth (see fig. 50). the laryngoscope must always and invariably be held in the left hand, and in such a manner that the greatest amount of traction is made at the swell of the horizontal bar of the handle, rather than on the vertical bar. the right hand is then free for the manipulation of forceps, and the insertion of the bronchoscope or other instrument. during introduction, the fingers of the right hand retract the upper lip so as to prevent its being pinched between the laryngoscope and the teeth. the introduction of the direct laryngoscope and exposure of the larynx is best described in two stages. 1. exposure and identification of the epiglottis. 2. elevation of the epiglottis and all the tissues attached to the hyoid bone, so as to expose the larynx to direct view. _first stage_.--the spatular end of the laryngoscope is introduced in the right side of the patient's mouth, along the right side of the anterior two-thirds of the tongue. it was the german method to introduce the laryngoscope over the dorsum of the tongue but in order to elevate this sometimes powerful muscular organ considerable force may be required, which exercise of force may be entirely avoided by crowding the tongue over to the left. when the posterior third stage of the tongue is reached, the tip of the laryngoscope is directed toward the midline and the dorsum of the tongue is elevated by a lifting motion imparted to the laryngoscope. the epiglottis will then be seen to project into the endoscopic field, as seen in fig. 54. [fig. 54.--end of the first of direct laryngoscopy, recumbent adult patient. the epiglottis is exposed by a lifting motion of the spatular tip on the tongue anterior to the epiglottis.] _second stage_.--the spatular end of the laryngoscope should now be tipped back toward the posterior wall of the pharynx, passed posterior to the epiglottis, and advanced about 1 cm. the larynx is now exposed by a motion that is best described as a suspension of the head and all the structures attached to the hyoid bone on the tip of the spatular end of the laryngoscope (fig. 55). particular care must be taken at this stage not to pry on the upper teeth; but rather to impart a lifting motion with the tip of the speculum without depressing the proximal tubular orifice. it is to be emphasized that while some pressure is necessary in the lifting motion, great force should never be used; the art is a gentle one. the first view is apt to find the larynx in state of spasm, and affords an excellent demonstration of the fact that the larynx can he completely closed without the aid of the epiglottis. usually little more is seen than the two rounded arytenoid masses, and, anterior to them, the ventricular bands in more or less close apposition hiding the cords (fig. 56). with deep general anesthesia or thorough local anesthesia the spasm may not be present. by asking the patient to take a deep breath and maintain steady breathing, or perhaps by requesting a phonatory effort, the larynx will open widely and the cords be revealed. if the anterior commissure of the larynx is not readily seen, the lifting motion and elevation of the head should be increased, and if there is still difficulty in exposing the anterior commissure the assistant holding the head should with the index finger externally on the neck depress the thyroid cartilage. if by this technic the larynx fails to be revealed the endoscopist should ask himself which of the following rules he has violated. [fig. 55.--schema illustrating the technic of direct laryngoscopy on the recumbent patient. the motion is imparted to the tip of the laryngoscope as if to lift the patient by his hyoid hone. the portion of the table indicated by the dotted line may be dropped or not, but the back of the head must never go lower than here shown, for direct laryngoscopy; and it is better to have it at least 10 cm. above the level of the table. the table may be used as a rest for the operator's left elbow to take the weight of the head. (note that in bronchoscopy and esophagoscopy the head section of the table must be dropped, so as to leave the head and neck of the patient out in the air, supported by the second assistant.)] [fig. 56.--endoscopic view at the end of the second stage of direct laryngoscopy. recumbent patient. larynx exposed waiting for larynx to relax its spasmodic contraction.] rules for direct laryngoscopy 1. the laryngoscope must always be held in the left hand, never in the right. 2. the operator's right index finger (never the left) should be used to retract the patient's upper lip so that there is no danger of pinching the lip between the instrument and the teeth. 3. the patient's head must always be exactly in the middle line, not rotated to the right or left, nor bent over sidewise; and the entire head must be forward with extension at the occipitoatloid joint only. 4. the laryngoscope is inserted to the right side of the anterior two-thirds of the tongue, the tip of the spatula being directed toward the midline when the posterior third of the tongue is reached. 5. the epiglottis must always be identified before any attempt is made to expose the larynx. 6. when first inserting the laryngoscope to find the epiglottis, great care should be taken not to insert too deeply lest the epiglottis be overridden and thus hidden. 7. after identification of the epiglottis, too deep insertion of the laryngoscope must be carefully avoided lest the spatula be inserted back of the arytenoids into the hypo-pharynx. 8. exposure of the larynx is accomplished by pulling forward the epiglottis and the tissues attached to the hyoid bone, and not by prying these tissues forward with the upper teeth as a fulcrum. 9. care must be taken to avoid mistaking the ary-epiglottic fold for the epiglottis itself. (most likely to occur as the result of rotation of the patient's head.) 10. the tube should not be retained too long in place, but should be removed and the patient permitted to swallow the accumulated saliva, which, if the laryngoscope is too long in place, will trickle down the trachea and cause cough. (swallowing is almost impossible while the laryngoscope is in position.) the secretions may be removed with the aspirator. 11. the patient must be instructed to breathe deeply and quietly without making a sound. [88] _difficulties of direct laryngoscopy_.--the larynx can be directly exposed in any patient whose mouth can be opened, although the ease varies greatly with the type of patient. failure to expose the epiglottis is usually due to too great haste to enter the speculum all the way down. the spatula should glide slowly along the posterior third of the tongue until it reaches the glossoepiglottic fossa, while at the same time the tongue is lifted; when this is done the epiglottis will stand out in strong relief. the beginner is apt to insert the speculum too far and expose the hypopharynx rather than the larynx. the elusiveness of the epiglottis and its tendency to retreat downward are very much accentuated in patients who have worn a tracheotomic cannula; and if still wearing it, the patient can wait indefinitely before opening his glottis. over extension of the patient's head is a frequent cause of difficulty. if the head is held high enough extension is not necessary, and the less the extension the less muscular tension there is in the anterior cervical muscles. only one arytenoid eminence may be seen. the right and the left look different. practice will facilitate identification, so that the endoscopist will at once know which way to look for the glottis. of the difficulties that pertain to the operator himself the greatest is lack of practice. he must learn to recognize the landmarks even though a high degree of spasm be present. the epiglottis and the two rounded eminences corresponding to the arytenoids must be in the mind's eye, for it is only on deep, relaxed inspiration that anything like a typical picture of the larynx will be seen. he must know also the right from the left arytenoid when only one is seen in order to know whether to move the lip of the laryngoscope to the right or the left for exposure of the interior of the larynx. _instruments for direct laryngoscopy_.--in undertaking direct laryngoscopy one must always be prepared for bronchoscopy, esophagoscopy, and tracheotomy, as well. preparations for bronchoscopy are necessary because the pathological condition may not be found in the larynx, and further search of the trachea or bronchi may be required. a foreign body in the larynx may be aspirated to a deeper location and could only be followed with the bronchoscope. sudden respiratory arrest might occur, from pathology or foreign body, necessitating the inserting of the bronchoscope for breathing purposes, and the insufflation of oxygen and amyl nitrite. trachectomy might be required for dyspnea or other reasons. it might be necessary to explore the esophagus for conditions associated with laryngeal lesions, as for instance a foreign body in the esophagus causing dyspnea by pressure. in short, when planning for direct laryngoscopy, bronchoscopy, or esophagoscopy, prepare for all three, and for tracheotomy. a properly done direct laryngoscopy would never precipitate a tracheotomy in an unanesthetized patient; but direct laryngoscopy has to deal so frequently with laryngeal stenosis, that routine preparation for tracheotomy a hundred unnecessary times is fully compensated for by the certainty of preparedness when the rare but urgent occasion arises. _direct laryngoscopy in children_.--the epiglottis in children is usually strongly curled, often omega shaped, and is very elusive and slippery. the larynx of a child is very freely movable in the neck during respiration and deglutition, and has a strong tendency to retreat downward during examination, and thus withdraw the epiglottis after the arytenoids have been exposed. in following down with the laryngoscope the speculum is prone to enter the hypopharynx. lifting in this location will expose the mouth of the esophagus and shut off the larynx, and may cause respiratory arrest. practice, however, will soon develop a technic and ability to recognize the landmarks in state of spasm, so that on exposing the approximated arytenoid eminences the endoscopist will maintain his position and wait for the larynx to open. the procedure should be done without any form of anesthesia for the following reasons: 1. anesthesia is unnecessary. 2. it is extremely dangerous in a dyspneic patient. 3. it is inadmissable in a patient with diphtheria. 4. if anesthesia is to be used, direct laryngoscopy will never reach its full degree of usefulness, because anesthesia makes a major procedure out of a minor one. 5. cocain in children is dangerous, and its application more annoying than the examination. _inducing a child to open its mouth (author's method)_.--the wounding of the child's mouth, gums, and lips, in the often inefficacious methods with gags, hemostats, raspatories, etcetera, are entirely unnecessary. the mouth of any child not unconscious can be opened quickly and without the slightest harm by passing a curved probe between the clenched jaws back of the molars and down back of the tongue toward the laryngopharynx. this will cause the child to gag, when its mouth invariably opens. [91] chapter viii--direct laryngoscopy (_continued_) _technic of laryngeal operations_.--preparation of the patient and anesthesia have been mentioned under their respective chapters. the prime essential of successful laryngeal operations is perfect mastery of continuous left-handed laryngeal exposure. the right hand must be equally trained in the manipulation of forceps, and the right eye to gauge depth. blood and secretions are best removed by a suction tube (fig. 9) inserted through the laryngoscope, or directly into the pharynx outside the laryngoscope. _for the removal of benign growths_ the author's papilloma forceps, fig. 29, or the laryngeal grasping forceps shown in fig. 17 will prove more satisfactory than any form of cutting forceps. these growths should be removed superficially flush with the normal structure. the crushing of the base incident to the plucking off of the growth causes its recession. by this conservative method damage to the cords and impairment of the voice are avoided. for growths in the anterior portion of the larynx, and in fact for the removal of most small benign growths, the anterior commissure laryngoscope is especially adapted. its shape allows its introduction into the vestibule of the larynx, and if desired it may be introduced through the glottic chink for the treatment of subglottic conditions. it will not infrequently be observed that a pedunculated subglottic growth which is found with difficulty will be pulled upward into view by the gauze swab introduced to remove secretions. the growth is then often held tightly between the approximated cords for a few seconds--perhaps long enough to grasp it with forceps. [92] _removal of growth from the laryngeal ventricle_.--after exposing the larynx in the usual manner, if the head is turned strongly to the right, the tip of the laryngoscope, directed from the right side of the mouth, may be used to lift the left ventricular hand and thus expose the ventricle, from which a growth may be removed in the usual manner (fig. 57). the right ventricle is exposed by working from the left side of the mouth. [fig. 57.-schema illustrating the lateral method of exposing a growth in the ventricle of morgagni, by bending the patient's head to the opposite side, while the second assistant externally fixes the larynx with his hand. m, patient's mouth; t, thyroid cartilage; r, right side; l, left. v, b, ventricular band. c, c, vocal cord. the circular drawing indicates the endoscopic view obtainable by this method. the tube, e, is dropped to the corner of the mouth, b, and the tube is inserted down to r. the lip of the spatula can then be used to lift the ventricular band so as to expose more of the ventricle. the drawing shows an unusually shallow ventricle.] _taking a laryngeal specimen for diagnosis_.--the diagnosis of carcinoma, sarcoma, and some other conditions can be made certain only by microscopic study of tissue removed from the growth. the specimen should be ample but will necessarily be small. if the suspected growth be small it should be removed entire, together with some of the basal tissues. if it is a large growth, and there are objections to its entire removal, the edge of the growth, including apparently normal as well as neoplastic tissue, is necessary. if it is a diffuse infiltrative process, a specimen should be taken from at least two locations. tissue for biopsy is to be taken with the punch forceps shown in fig. 28 or that in fig. 33. the forceps may be inserted through the tube or from the angle of the mouth; the "extubal" method (see fig. 58). [fig. 58.--schema illustrating removal of a tumor from the upper part of the larynx by the author's "extubal" method for large tumors. the large alligator basket punch forceps, f, is inserted from the right corner of the mouth and the jaws are placed over the tumor, t, under guidance of the eye looking through the laryngoscope, l. this method is not used for small tumors. it is excellent for amputation of the epiglottis with these same punch forceps or with the heavy snare.] _removal of large benign tumors above the cords_ may be done with the snare or with the large laryngeal punch forceps. both are used in the extubal method. _amputation of the epiglottis_ for palliation of odynophagia or dysphagia in tuberculous or malignant disease, is of benefit when the ulceration is confined to this region; though as to tuberculosis the author feels rather conservatingly inclined. early malignancy of the extreme tip can be cured by such means. the function of the epiglottis seems to be to split the food bolus and direct its portions laterally into the pyriform sinuses, rather than to take any important part in the closure of the larynx. following the removal of the epiglottis there is rarely complaint of food entering the larynx. the projecting portion of the epiglottis may be amputated with a heavy snare, or by means of the large laryngeal punch forceps (fig. 33). _endoscopic operations for laryngeal stenosis_.--web formations may be excised with sliding punch forceps, or if the web is due to contraction only, incision of the true band may allow its retraction. in some instances liberation of adhesions will favor the formation of adventitious vocal cords. a sharp anterior commissure is a large factor in good phonation. _endoscopic evisceration of the larynx_ will cure a few cases of laryngeal cicatricial stenosis, and should be tried before resorting to laryngostomy. a sliding punch forceps is used to remove all the tissue in the larynx out to the perichondrium, but care should be taken in cicatricial cases to avoid removing any part of either arytenoid cartilage. in cases of posticus paralysis the excision may include portions of the vocal processes of the arytenoids. ventriculocordectomy is preferable to evisceration. the ventricular floor is removed with punch forceps (fig. 33) first on one side, then after two months, on the other. _vocal results_.--a whispering voice can always be had as long as air can pass through the larynx, and this may be developed to a very loud penetrating stage whisper. if the arytenoid motility has been uninjured the repeated pulls on the scar tissue may draw out adventitious bands and develop a loud, useful, though perhaps rough and inflexible voice. _galvano-cauterization_ is the best method of treatment for chronic subglottic edema or hyperplasia such as is seen in children following diphtheria, when the stenosis produced prevents extubation or decannulation. the utmost caution should be used to avoid deep cauterizations; they are almost certain to set up perichondritis which will increase the stenosis. some of the most difficult cases that have come to the author have been previously cauterized too deeply. _galvano-cautery puncture_ of tuberculous infiltrations of the larynx at times yields excellent results in cases with mild pulmonary lesions, and has quite replaced the use of the curette, lactic acid, and other caustics. the direct method of exposing the larynx renders the application of the cautery point easy and accurate. in severely stenosed tuberculous larynges a tracheotomy should first be done, for though the reaction is slight it might be sufficient to close a narrowed glottis. the technic is the usual one for laryngeal operations. local anesthesia suffices. the larynx is exposed. the rheostat having been previously adjusted to heat the electrode to nearly white heat, the circuit is broken and the electrode introduced cold. when the point is in contact with the desired location the current is turned on and the point thrust in as deeply as desired. usually it should penetrate until a firm resistance is felt; but care must be used not to damage the cricoarytenoid joint. the circuit is broken at the instant of withdrawal. punctures should be made as nearly as possible perpendicular to the surface, so as to minimize the destruction of epithelium and thus lessen the reaction. a minute gray fibrous slough detaches itself in a few days. cautery puncture should be repeated every two or three weeks, selecting a new location each time, until the desired result is obtained. great caution, as mentioned above, must be used to avoid setting up perichondritis. many cases of laryngeal tuberculosis will recover as quickly by silence and a general antituberculous regime. _radium_, in form of capsules or of needles inserted in the tissues may be applied with great accuracy; but the author is strongly impressed with pyriform sinus applications by the freer method. _after-care of endolaryngeal operations_ includes careful cleansing of the teeth and mouth; and if the extrinsic area of the larynx is involved in the wound, sterile liquid food and water should be given for four days. the patient should be watched for complications by a special nurse who is familiar with the signs of laryngeal dyspnea (q.v.). _complications during endolaryngeal operations_ are rare. dyspnea may require tracheotomy. idiosyncrasy to cocain, or the sight or taste of blood may nauseate the patient and cause syncope. serious hemorrhage could occur only in a hemophile. the careless handling of a bite block might damage a frail tool or dental fixture. _complications after endolaryngeal operations_ are unusual. carelessness in asepsis has been known to cause cervical cellulitis. emphysema of the neck has occurred. edema of the larynx occasionally occurs, and might necessitate tracheotomy. serious bleeding after operation is very rare except in bleeders. hemorrhage within the larynx can be stopped by the introduction of a roll of gauze from above, tracheotomy having been previously performed. morphin subcutaneously administered, has a constricting action on the vessels which renders it of value in controlling hemorrhage. [97] chapter ix--introduction of the bronchoscope no one should do bronchoscopy until he is able to expose the glottis by left-handed direct laryngoscopy in less than one minute. when he has mastered this, one minute more should be sufficient to introduce the bronchoscope into the trachea. technic of bronchoscopy local anesthesia is usually employed in the adult. the patient is placed in the boyce position shown in fig. 51, with head and shoulders projecting over the edge of the table and supported by an assistant. the glottis is exposed by left-handed laryngoscopy. the instrument-assistant now inserts the distal end of the bronchoscope into the lumen of the laryngoscope, the handle being directed to the right in a horizontal position. the operator now grasps the bronchoscope, his eye is transferred from the laryngoscope to the bronchoscope, and the bronchoscope is advanced and so directed that a good view of the glottis is obtained. the slanted end of the bronchoscope should then be directed to the left, so as clearly to expose the left cord. in this position it will be found that the tip of the slanted end is in the center of the glottic chink and will slip readily into the trachea. no great force should be used, because if the bronchoscope does not go through readily, either the tube is too large a size or it is not correctly placed (fig. 60). normally, however, there is some slight resistance, which in cases of subglottic laryngitis may be considerable. the trained laryngologist will readily determine by sense of touch the degree of pressure necessary to overcome it. when the bronchoscope has been inserted to about the second or third tracheal ring, the heavy laryngoscope is removed by rotating the handle to the left, removing the slide, and withdrawing the instrument. care must be taken that the bronchoscope is not withdrawn or coughed out during the removal of the laryngoscope; this can be avoided by allowing the ocular end to rest against the gown-covered chest of the operator. if preferred the operator may train his instrumental assistant to take off the laryngoscope, while the operator devotes his attention to preventing the withdrawal of the bronchoscope by holding the handle with his right hand. at the moment of insertion of the bronchoscope through the glottis, an especially strong upward lift on the beak of the spatula will facilitate the passage. it is necessary to be certain that the axis of the bronchoscope corresponds to the axis of the trachea, in order to avoid injury to the subglottic tissue which might be followed by subglottic edema (fig. 47). if the subglottic region is already edematous and causes resistance, slight rotation to the laryngoscope, and bronchoscope will cause the bronchoscope to enter more easily.

[fig. 62.--insertion of the bronchoscope. note direction of the trachea as indicated by the bronchoscope. note that the patient's head is held above the level of the table. the assistant's left hand should be at the patient's mouth holding the bite-block. this is removed and the assistant is on the wrong side of the table in the illustration in order not to hide the position of the operator's hands. note the handle of the bronchoscope is to the right.] [fig. 63.--the heavy laryngoscope has been removed leaving the light bronchoscope in position. the operator is inserting forceps. note how the left hand of the operator holds the tube lightly between the thumb and first two fingers of the left hand, while the last two fingers are hooked over the upper teeth of the patient "anchoring" the tube to prevent it moving in or out or otherwise changing the relation of the distal tube-mouth to a foreign body or a growth while forceps are being used. thus, also, any desired location of the tube can be maintained in systematic exploration. the assistant's left hand is dropped out of the way to show the operator's method. the assistant during bronchoscopy holds the bite-block like a thimble on the index finger of the left hand, and the assistant should be on the right side of the patient. he is here put wrongly on the left side so as not to hide the instruments and the manner of holding them.] _examination of the trachea and bronchi_.--all bronchial orifices must be identified _seriatim_; because this is the only way by which the bronchoscopist can know what part of the tree he is examining. appearances alone are not enough. it is the order in which they are exposed that enables the inexperienced operator to know the orifices. after the removal of the laryngoscope, the bronchoscope is to be held by the left hand like a billiard cue, the terminal phalanges of the left middle and ring fingers hooking over the upper teeth, while the thumb and index finger hold the bronchoscope, clamping it to the teeth tightly or loosely as required (fig. 63). thus the tube may be anchored in any position, or at any depth, and the right hand which was directing the tube may be used for the manipulation of instruments. the grasp of the bronchoscope in the right hand should be similar to that of holding a pen, that is, the thumb, first, and second fingers, encircle the shaft of the tube. the bronchoscope should never be held by the handle (fig. 64) for this grasp does not allow of tactile sense transmission, is rigid, awkward, and renders rotation of the tube a wrist motion instead of but a gentle finger action. any secretion in the trachea is to be removed by sponge pumping before the bronchoscope is advanced. the inspection of the walls of the trachea is accomplished by weaving from side to side and, if necessary, up and down; the head being deflected as required during the search of the passages, so that the larynx be not made the fulcrum in the lever-like action. [fig. 64.--at a is shown an incorrect manner of holding the bronchoscope. the grasp is too rigid and the position of the hand is awkward. b, correct manner, the collar being held lightly between the finger and the thumb the thumb must not occlude the tube mouth.] _the fulcrum of the bronchoscopic lever is at the upper thoracic aperture; never at the larynx_.--disregard of this rule will cause subglottic edema and will limit the lateral motion of the tip of the bronchoscope. it is the function of the assistant to make the head and neck follow the direction of the proximal end of the bronchoscope and thus avoid any pressure on the larynx (see peroral endoscopy, fig. 135, p. 164). in passing down the trachea the following two rules must be kept in mind: 1. before attempting to enter either main bronchus the carina must be identified. 2. before entering either main bronchus the orifices of both should be identified and inspected. _the carina_ is identified as a sharp vertical spur (recumbent patient) at the distal end of the trachea, on either side of which are the openings of the main bronchi. as the carina is situated to the left of the midline of the trachea, the lip of the bronchoscope should be turned toward the left, and slight lateral pressure should be made on the left tracheal wall while the head of the patient is held slightly to the right. this will expose the left bronchial orifice and carina. _entering the bronchi_.--the lip of the bronchoscope should be turned in the direction of the bronchus to be explored, and the axis of the bronchoscope should be made to correspond as nearly as possible to the axis of this bronchus. the position of the lip is designated by the direction taken by the handle. upon entering the right bronchus, the handle of the bronchoscope is turned horizontally to the right, and at the same time the assistant deflects the head to the left. _the right upper-lobe bronchus_ is recognized by its vertical spur; the orifice is exposed by displacing the right lateral wall of the right main bronchus at the level of the carina. usually this orifice will be thus brought into view. if not the bronchoscope may be advanced downward 1 or 2 cm., carefully to avoid overriding. this branch is sometimes found coming off the trachea itself, and even if it does not, the overriding of the orifice is certain if the right bronchus is entered before search is made for the upper-lobe-bronchial orifice. the head must be moved strongly to the left in order to view the orifice. a lumen image of the right upper-lobe bronchus is not obtainable because of the sharp angles at which it is given off. _the left upper-lobe bronchus_ is entered by keeping the handle of the bronchoscope (and consequently the lip) to the left, and, by keeping the head of the patient strongly to the right as the bronchoscopist goes down the left main bronchus. this causes the lip of the bronchoscope to bear strongly on the left wall of the left main bronchus, consequently the left upper-lobe-bronchial orifice will not be overridden. the spur separating the upper-lobe-bronchial orifice from the stem bronchus is at an angle approximately from two to eight o'clock, as usually seen in the recumbent patient. a lumen image of a descending branch of the upper-lobe bronchus is often obtained, if the patient's head be borne strongly enough to the right. [fig. 65.--schema illustrating the entering of the anteriorly branching middle lobe bronchus. t, trachea; b, orifice of left main bronchus at bifurcation of trachea. the bronchoscope, s, is in the right main bronchus, pointing in the direction of the right inferior lobe bronchus, i. in order to cause the lip to enter the middle lobe bronchus, m, it is necessary to drop the head so that the bronchoscope in the trachea tt, will point properly to enable the lip of the tube mouth to enter the middle lobe bronchus, as it is seen to have done at ml.] branches of the stem bronchus in either lung are exposed, or their respective lumina presented, by manipulation of the lip of the bronchoscope, with movement of the head in the required direction. posterior branches require the head quite high. a large one in the left stem just below the left upper-lobe bronchus is often invaded by foreign bodies. anterior branches require lowering the head. the _middle-lobe bronchus_ is the largest of all anterior branches. its almost horizontal spur is brought into view by directing the lip of the bronchoscope upward, and dropping the head of the patient until the lip bears strongly on the anterior wall of the right bronchus (see fig. 65). [106] chapter x--introduction of the esophagoscope the esophagoscope is to be passed only with ocular guidance, never blindly with a mandrin or obturator, as was done before the bevel-ended esophagoscope was developed. blind introduction of the esophagoscope is equally as dangerous as blind bouginage. it is almost certain to cause over-riding of foreign bodies and disease. in either condition perforation of the esophagus is possible by pushing a sharp foreign body through the normal wall or by penetrating a wall weakened by disease. landmarks must be identified as reached, in order to know the locality reached. the secretions present form sufficient lubrication for the instrument. a clear conception of the endoscopic anatomy, the narrowings, direction, and changes of direction of the axis of the esophagus, are necessary. the services of a trained assistant to place the head in the proper sequential "high-low" positions are indispensible (figs. 52 and 70). introduction may be divided into four stages. 1. entering the right pyriform sinus. 2. passing the cricopharyngeus. 3. passing through the thoracic esophagus. 4. passing through the hiatus. the patient is placed in the boyce position as described in chapter vi. as previously stated, the esophagus in its upper portion follows the curves of the cervical and dorsal spine. it is necessary, therefore, to bring the cervical spine into a straight line with the upper portion of the dorsal spine and this is accomplished by elevation of the head--the "high" position (figs. 66-71). [plate iii--esophagoscopic views from oil-color drawings from life, by the author: 1, direct view of the larynx and laryngopharynx in the dorsally recumbent patient, the epiglottis and hyoid bone being lifted with the direct laryngoscope or the esophageal speculum. the spasmodically adducted vocal cords are partially hidden by the over-hang of the spasmodically prominent ventricular hands. posterior to this the aryepiglottic folds ending posteriorly in the arytenoid eminences are seen in apposition. the esophagoscope should be passed to the right of the median line into the right pyriform sinus, represented here by the right arm of the dark crescent. 2, the right pyriform sinus in the dorsally recumbent patient, the eminence at the upper left border, corresponds to the edge of the cricoid cartilage. 3, the cricopharyngeal constriction of the esophagus in the dorsally recumbent patient, the cricoid cartilage being lifted forward with the esophageal speculum. the lower (posterior) half of the lumen is closed by the fold corresponding to the orbicular fibers of the cricopharyngeus which advances spasmodically from the posterior wall. (compare fig. 10.) this view is not obtained with an esophagoscope. 4, passing through the right pyriform sinus with the esophagoscope; dorsally recumbent patient. the walls seem in tight apposition, and, at the edges of the slit-like lumen, bulge toward the observer. the direction of the axis of the slit varies, and in some instances it is like a rosette, depending on the degree of spasm. 5, cervical esophagus. the lumen is not so patulent during inspiration as lower down; and it closes completely during expiration. 6, thoracic esophagus; dorsally recumbent patient. the ridge crossing above the lumen corresponds to the left bronchus. it is seldom so prominent as in this patient, but can always be found if searched for. 7, the normal esophagus at the hiatus. this is often mistaken for the cardia by esophagoscopists. it is more truly a sphincter than the cardia itself. in the author's opinion there is no truly sphincteric action at the cardia. it is the failure of this hiatal sphincter to open as in the normal deglutitory cycle that produces the syndrome called "cardiospasm." 8, view in the stomach with the open-tube gastroscope. the form of the folds varies continually. 9, sarcoma of the posterior wall of the upper third of the esophagus in a woman of thirty-one years. seen through the esophageal speculum, patient sitting. the lumen of the mouth of the esophagus, much encroached upon by the sarcomatous infiltration, is seen at the lower part of the circle. 10, coin (half-dollar) wedged in the upper third of the esophagus of a boy aged fourteen years. seen through the esophageal speculum, recumbent patient. forceps are retracting the posterior lip of the esophageal "mouth" preparatory to removal. 11, fungating squamous-celled epithelioma in a man of seventy-four years. fungations are not always present, and are often pale and edematous. 12, cicatricial stenosis of the esophagus due to the swallowing of lye in a boy of four years. below tile upper stricture is seen a second stricture. an ulcer surrounded by an inflammatory areola and the granulation tissue together illustrates the etiology of cicatricial tissue. the fan-shaped scar is really almost linear, but it is viewed in perspective. patient was cured by esophagoscopic dilatation. 13, angioma of the esophagus in a man of forty years. the patient had hemorrhoids and varicose veins of the legs. 14, luetic ulcer of the esophagus 26 cm. from the upper teeth in a woman of thirty-eight years. two scars from healed ulcerations are seen in perspective on the anterior wall. branching vessels are seen in the livid areola of the ulcers. 15, tuberculosis of the esophagus in a man of thirty-four years. 16, leukoplakia of the esophagus near the hiatus in a man aged fifty-six years.] the hypopharynx tapers down to the gullet like a funnel, and the larynx is suspended in its lumen from the anterior wall. the larynx is attached only to the anterior wall, but is held closely against the posterior pharyngeal wall by the action of the inferior constrictor of the pharynx, and particularly by its specialized portion--the cricopharyngeus muscle. a bolus of food is split by the epiglottis and the two portions drifted laterally into the pyriform sinuses, the recesses seen on either side of the larynx. but little of the food bolus passes posterior to the larynx during the act of swallowing. it is through the pyriform sinus that the esophagoscope is to be inserted, thereby following the natural food passage. to insert the esophagoscope in the midline, posterior to the arytenoids, requires a degree of force dangerous to exert and almost certain to produce damage to the cricoarytenoid joint or to the pharyngeal wall, or to both. the esophagoscope is steadied by the left hand like a billiard cue, the terminal phalanges of the left middle and ring fingers hooked over the upper teeth, while the left index finger and thumb encircle the tube and retract the upper lip to prevent its being pinched between the tube and upper teeth. the right hand holds the tube in pen fashion at the collar of the handle, not by the handle. during introduction the handle is to be pointed upward toward the zenith. _stage i. entering the right pyriform sinus_.--the operator standing (as in fig. 66), inserts the esophagoscope along the right side of the tongue as far as and down the posterior pharyngeal wall. a lifting motion imparted to the tip of the esophagoscope by the left thumb will bring the rounded right arytenoid eminence into view (a, fig. 69). this is the landmark of the pyriform sinus, and care must be taken to avoid injury by hooking the tube mouth over it or its fellow. the tip of the tube should now be directed somewhat toward the midline, remembering the funnel shape of the hypopharynx. it will then be found to glide readily through the right pyriform sinus for 2 or 3 cm., when it comes to a full stop, and the lumen disappears. this is the spasmodically closed cricopharyngeal constriction. [fig. 66.--esophagoscopy by the author's "high-low" method. first stage. "high" position. finding the right pyriform sinus. in this and the second stage the patient's vertex is about 15 cm. above the level of the table.] _stage 2. passing the cricopharyngeus_ is the most difficult part of esophagoscopy, especially if the patient is unanesthetized. local anesthesia helps little, if at all. the handle of the esophagoscope is still pointing upward and consequently we are sure that the lip of the esophagoscope is directed anteriorly. force must not be used, but steady firm pressure against the tonically contracted cricopharyngeus is made, while at the same time the distal end of the esophagoscope is lifted by the left thumb. at the first inspiration a lumen will usually appear in the upper portion of the endoscopic field. the tip of the esophagoscope enters this lumen and the slanted end slides over the fold of the cricopharyngeus into the cervical esophagus. there is usually from 1 to 3 cm. of this constricted lumen at the level of the cricopharyngeus and the subjacent orbicular esophageal fibers. [109] [fig. 67.--schematic illustration of the author's "high-low" method of esophagoscopy. in the first and second stages the patient's head fully extended is held high so as to bring it in line with the thoracic esophagus, as shown above. the rose position is shown by way of accentuation.] [fig. 68.--schematic illustration of the anatomic basis for difficulty in introduction of the esophagoscope. the cricoid cartilage is pulled backward against the cervical spine, by the cricopharyngeus, so strongly that it is difficult to realize that the cricopharyngeus is not inserted into the vertebral periosteum instead of into the median raphe.] [fig. 69.--the upper illustration shows movements necessary for passing the cricopharyngeus. the lower illustration shows schematically the method of finding the pyriform sinus in the author's method of esophagoscopy. the large circle represents the cricoid cartilage. g, glottic chink, spasmodically closed; vb, ventricular band; a, right arytenoid eminence; p, right pyriform sinus, through which the tube is passed in the recumbent posture. the pyriform sinuses are the normal food passages.] _stage 3. passing through the thoracic esophagus_.--the thoracic esophagus will be seen to expand during inspiration and contract during expiration, due to the change in thoracic pressure. the esophagoscope usually glides easily through the thoracic esophagus if the patient's position is correct. after the levels of the aorta and left bronchus are passed the lumen of the esophagus seems to have a tendency to disappear anteriorly. the lumen must be kept in axial view and the head lowered as required for this purpose. _stage 4. passing through the hiatus esophageus_.--when the head is dropped, it must at the same time be moved horizontally to the right in order that the axis of the tube shall correspond to the axis of the lower third of the esophagus, which deviates to the left and turns anteriorly. the head and shoulders at this time will be found to be considerably below the plane of the table top (fig. 71). the hiatal constriction may assume the form of a slit or rosette. if the rosette or slit cannot be promptly found, as may be the case in various degrees of diffuse dilatation, the tube mouth must be shifted farther to the left and anteriorly. when the tube mouth is centered over the hiatal constriction moderately firm pressure continued for a short time will cause it to yield. then the tube, maintaining this same direction will, without further trouble glide into and through the abdominal esophagus. the cardia will not be noticed as a constriction, but its appearance will be announced by the rolling in of reddish gastric mucosal folds, and by a gush of fluid from the stomach. [fig. 70.--schematic illustration of the author's "high-low" method of esophagoscopy, fourth stage. passing the hiatus. the head is dropped from the position of the 1st and 2nd stages, cl, to the position t, and at the same time the head and shoulders are moved to the right (without rotation) which gives the necessary direction for passing the hiatus.] [fig. 71.--esophagoscopy by the author's "high-low" method. stage 4. passing the hiatus the patient's vertex is about 5 cm. below the top of the table.] _normal esophageal mucosa_ under proper illumination is glistening and of a yellowish or bluish pink. the folds are soft and velvety, rendering infiltration quickly noticeable. the cricoid cartilage shows white through the mucosa. the gastric mucosa is a darker pink than that of the esophagus and when actively secreting, its color in some cases tends toward crimson. _secretions_ in the esophagus are readily aspirated through the drainage canal by a negative pressure pump. food particles are best removed by "sponge pumping," or with forceps. should the drainage canal become obstructed positive pressure from the pump will clear the canal. _difficulties of esophagoscopy_.--the beginner may find the esophagoscope seemingly rigidly fixed, so that it can be neither introduced nor withdrawn. this usually results from a wedging of the tube in the dental angle, and is overcome by a wider opening of the jaws, or perhaps by easing up of the bite block, but most often by correcting the position of the patient's head. if the beginner cannot start the tube into the pyriform sinus in an adult, it is a good plan to expose the arytenoid eminence with the laryngoscope and then to insert the 7 mm. esophagoscope into the right pyriform sinus by direct vision. passing the cricopharyngeal and hiatal spasmodically contracted narrowings will prove the most trying part of esophagoscopy; but with the head properly held, and the tube properly placed and directed, patient waiting for relaxation of the spasm with gentle continuous pressure will usually expose the lumen ahead. in his first few esophagoscopies the novice had best use general anesthesia to avoid these difficulties and to accustom himself to the esophageal image. in the first favorable subject--an emaciated individual with no teeth--esophagoscopy without anesthesia should be tried. in cases of kyphosis it is a mistake to try to straighten the spine. the head should be held correspondingly higher at the beginning, and should be very slowly and cautiously lowered. once inserted, the esophagoscope should not be removed until the completion of the procedure, unless respiratory arrest demands it. occasionally in stenotic conditions the light may become covered by the upwelling of a flood of fluid, and it will be thought the light has gone out. as soon as the fluid has been aspirated the light will be found burning as brightly as before. if a lamp should fail it is unnecessary to remove the tube, as the light carrier and light can be withdrawn and quickly adjusted. a complete instrument equipment with proper selection of instruments for the particular case are necessary for smooth working. _ballooning esophagoscopy_.--by inserting the window plug shown in fig. 6 the esophagus may be inflated and studied in the distended state. the folds are thus smoothed out and constrictions rendered more marked. ether anesthesia is advocated by mosher. the danger of respiratory arrest from pressure, should the patient be dyspneic, is always present unless the anesthetic be given by the intratracheal method. if necessary to use forceps the window cap is removed. if the perforated rubber diaphragm cap be substituted the esophagus can be reballooned, but work is no longer ocularly guided. the fluoroscope may be used but is so misleading as to render perforation and false passage likely. _specular esophagoscopy_.--inspection of the hypopharynx and upper esophagus is readily made with the esophageal speculum shown in fig. 4. high lesions and foreign bodies lodged behind the larynx are thus discovered with ease, and such a condition as a retropharyngeal abscess which has burrowed downward is much less apt to be overlooked than with the esophagoscope. high strictures of the esophagus may be exposed and treated by direct visual bouginage until the lumen is sufficiently dilated to allow the passage of the esophagoscope for bouginage of the deeper strictures. _technic of specular esophagoscopy_.--recumbent patient. boyce position. the larynx is to be exposed as in direct laryngoscopy, the right pyriform sinus identified, the tip of the speculum inserted therein, and gently insinuated to the cricopharyngeal constriction. too great extension of the head is to be avoided--even slight flexion at the occipito-atloid joint may be found useful at times. moderate anterior or upward traction pulls the cricoid away from the posterior pharyngeal wall and the lumen of the esophagus opens above a crescentic fold (the cricopharyngeus). the speculum readily slides over this fold and enters the cervical esophagus. in searching for foreign bodies in the esophagus the speculum has the disadvantage of limited length, so that should the foreign body move downward it could not be followed. _complications following esophagoscopy_.--these are to be avoided in large measure by the exercise of gentleness, care, and skill that are acquired by practice. if the instructions herein given are followed, esophagoscopy is absolutely without mortality apart from the conditions for which it is done. injury to the crico-arytenoid joint may simulate recurrent paralysis. posticus paralysis may occur from recurrent or vagal pressure by a misdirected esophagoscope. these conditions usually recover but may persist. perforation of the esophageal wall may cause death from septic mediastinitis. the pleura may be entered,--pyopneumothorax will result and demand immediate thoracotomy and gastrostomy. aneurysm of the aorta may be ruptured. patients with tuberculosis, decompensating cardiovascular lesions, or other advanced organic disease, may have serious complications precipitated by esophagoscopy. _retrograde esophagoscopy_.--the first step is to get rid of the gastric secretions. there is always fluid in the stomach, and this keeps pouring out of the tube in a steady stream. fold after fold is emptied of fluid. once the stomach is empty, the search begins for the cardial opening. the best landmark is a mark with a dermal pencil on the skin at a point corresponding to the level of the hiatus esophageus. when it is desired to do a retrograde esophagoscopy and the gastrostomy is done for this special purpose, it is wise to have it very high. once the cardia is located and the esophagus entered, the remainder of the work is very easy. bouginage can be carried out from below the same as from above and may be of advantage in some cases. strictural lumina are much more apt to be concentric as approached from below because there has been no distortion by pressure dilatation due to stagnation of the food operating through a long period of time. at retrograde esophagoscopy there seems to be no abdominal esophagus and no cardia. the esophagoscope encounters only the diaphragmatic pinchcock which seems to be at the top of the stomach like the puckering string at the top of a bag. retrograde esophagoscopy is sometimes useful for "stringing" the esophagus in cases in which the patient is unable to swallow a string because he is too young or because of an epithelial scaling over of the upper entrance of the stricture. in such cases the smallest size of the author's filiform bougies (fig. 40) is inserted through the retrograde esophagoscope (fig. 43) and insinuated upward through the stricture. when the tip reaches the pharynx coughing, choking and gagging are noticed. the filiform end is brought out the mouth sufficiently far to attach a silk braided cord which is then pulled down and out of the gastrostomic opening. the braided silk "string" must be long enough so that the oral and the abdominal ends can be tied together to make it "endless;" but before doing so the oral end should be drawn through nose where it will be less annoying than in the mouth. the purpose of the "string" is to pull up the retrograde bougies (fig. 35) [117] chapter xi--acquiring skill endoscopic ability cannot be bought with the instruments. as with all mechanical procedures, facility can be obtained only by educating the eye and the fingers in repeated exercise of a particular series of maneuvers. as with learning to play a musical instrument, a fundamental knowledge of technic, positions, and landmarks is necessary, after which only continued manual practice makes for proficiency. for instance, efficient use of forceps requires that they be so familiar to the grasp that their use is automatic. endoscopy is a purely manual procedure, hence to know how is not enough: manual practice is necessary. even in the handling of the electrical equipment, practice in quickly locating trouble is as essential as theoretic knowledge. there is no mystery about electric lighting. no source of illumination other than electricity is possible for endoscopy. therefore a small amount of electrical knowledge, rendered practical by practice, is essential to maintain the simple lighting system in working order. it is an insult to the intelligence of the physician to say that he cannot master a simple problem of electric testing involving the locating of one or more of five possibilities. it is simply a matter of memorizing five tests. it is repeated for emphasis that a commercial current reduced by means of a rheostat should never be used as a source of current for endoscopy with any kind of instrument, because of the danger to the patient of a possible "grounding" of the circuit during the extensive moist contact of a metallic endoscopic tube in the mediastinum. the battery shown in fig. 8 should be used. the most frequent cause of trouble is the mistake of over-illuminating the lamps. _the lamp should not be over-illuminated to the dazzling whiteness usually used in flash lights_. excessive illumination alters the proper perception of the coloring of the mucosa, besides shortening the life of the lamps. the proper degree of brightness is obtained when, as the current is increased, the first change from yellow to white light is obtained. never turn up the rheostat without watching the lamp. _testing for electric defects_.--these tests should be made beforehand; not when about to commence introduction. if the first lamp lights up properly, use it with its light-carrier to test out the other cords. if the lamp lights up, but flickers, locate the trouble before attempting to do an endoscopy. if shaking the carrier cord-terminal produces flickering there may be a film of corrosion on the central contact of the light carrier that goes into the carrier cord-terminal. if the lamp fails to show a light, the trouble may be in one of five places which should be tested for in the following order and manner. 1. the lamp may not be firmly screwed into the light-carrier. withdraw the light-carrier and try screwing it in, though not too strongly, lest the central wire terminal in the lamp be bent over. 2. the light-carrier may be defective. 3. the cord may be defective or its terminals not tight in the binding posts. if screwing down the thumb nuts does not produce a light, test the light-carrier with lamp on the other cords. reserve cords in each pair of binding posts are for use instead of the defective cords. the two sets of cords from one pair of binding posts should not be used simultaneously. 4. the lamp may be defective. try another lamp. 5. the battery may be defective. take a cord and light-carrier with lamp that lights up, detaching the cord-terminals at the binding posts, and attach the terminals to the binding posts of the battery to be tested. _efficient use of forceps_ requires previous practice in handling of the forceps until it has become as natural and free from thought as the use of knife and fork. indeed the coordinate use of the bronchoscopic tube-mouth and the forceps very much resembles the use of knife and fork. yet only too often a practitioner will telegraph for a bronchoscope and forceps, and without any practice start in to remove an entangled or impacted foreign body from the tiny bronchi of a child. failure and mortality are almost inevitable. a few hundred hours spent in working out, on a bit of rubber tubing, the various mechanical problems given in the section on that subject will save lives and render easily successful many removals that would otherwise be impossible. it is often difficult for the beginner to judge the distance the forceps have been inserted into the tube. this difficulty is readily solved if upon inserting the forceps slowly into the tube, he observes that as the blades pass the light they become brightly illuminated. by this _light reflex_ it is known, therefore, that the forceps blades are at the tube-mouth, and distance from this point can be readily gauged. excellent practice may be had by picking up through the bronchoscope or esophagoscope black threads from a white background, then white threads from a black background, and finally white threads on a white background and black threads on a black background. this should be done first with the 9 mm. bronchoscope. it is to be remembered that the majority of foreign body accidents occur in children, with whom small tubes must be used; therefore, practice work, after say the first 100 hours, should be done with the 5 mm. bronchoscope and corresponding forceps rather than adult size tubes, so that the operator will be accustomed to work through a small calibre tube when the actual case presents itself. [120] _cadaver practice_.--the fundamental principles of peroral endoscopy are best taught on the cadaver. it is necessary that a specially prepared subject be had, in order to obtain the required degree of flexibility. injecting fluid of the following formula worked out by prof. j. parsons schaeffer for the bronchoscopic clinic courses, has proved very satisfactory: sodium carbonate--1 1/2 lbs. white arsenic--2 1/2 lbs. potassium nitrate--3 lbs. water--5 gal. boil until arsenic is dissolved. when cold add: carbolic acid 1500 c.c. glycerin 1250 c.c. alcohol (95%) 1250 c.c. for each body use about 3 gal. of fluid. the method of introduction of the endoscopic tube, and its various positions can be demonstrated and repeatedly practiced on the cadaver until a perfected technic is developed in both the operator and assistant who holds the head, and the one who passes the instruments to the operator. in no other manner can the landmarks and endoscopic anatomy be studied so thoroughly and practically, and in no other way can the pupil be taught to avoid killing his patient. the danger-points in esophagoscopy are not demonstrable on the living without actually incurring mortality. laryngeal growths may be simulated, foreign body problems created and their mechanical difficulties solved and practice work with the forceps and tube perfected. _practice on the rubber-tube manikin_.--this must be carried out in two ways. 1. general practice with all sorts of objects for the education of the eye and the fingers. 2. before undertaking a foreign body case, practice should be had with a duplicate of the foreign body. it is not possible to have a cadaver for daily practice, but fortunately the eye and fingers may be trained quite as effectually by simulating foreign body conditions in a small red rubber tube and solving these mechanical problems with the bronchoscope and forceps. the tubing may be placed on the desk and held by a small vise (fig. 72) so that at odd moments during the day or evening the fascinating work may be picked up and put aside without loss of time. complicated rubber manikins are of no value in the practice of introduction, and foreign body problems can be equally well studied in a piece of rubber tubing about 10 inches long. no endoscopist has enough practice on the living subject, because the cases are too infrequent and furthermore the tube is inserted for too short a space of time. practice on the rubber tube trains the eye to recognize objects and to gauge distance; it develops the tactile sense so that a knowledge of the character of the object grasped or the nature of the tissues palpated may be acquired. before attempting the removal of a particular foreign body from a living patient, the anticipated problem should be simulated with a duplicate of the foreign body in a rubber tube. in this way the endoscopist may precede each case with a practical experience equivalent to any number of cases of precisely the same kind of foreign body. if the object cannot be removed from the rubber tube without violence, it is obvious that no attempt should be made on the patient until further practice has shown a definite method of harmless removal. during practice work the value of the beveled lip of the bronchoscope and esophagoscope in solving mechanical problems will be evidenced. with it alone, a foreign body may be turned into favorable positions for extraction, and folds can always be held out of the way. sufficient combined practice with the bronchoscope and the forceps enable the endoscopist easily to do things that at first seem impossible. it is to be remembered that lateral motion of the long slender tube-forceps cannot be controlled accurately by the handle, this is obtained by a change in position of the endoscopic tube, the object being so centered that it is grasped without side motion of the forceps. when necessary, the distal end of the forceps may be pushed laterally by the manipulation of the bronchoscope. [fig. 72.--a simple manikin. the weight of the small vise serves to steady the rubber tubing. by the use of tubing of the size of the invaded bronchus and a duplicate of the foreign body, any mechanical problem can he simulated for solution or for practice, study of all possible presentations, etc.] _practice on the dog_.--having mastered the technic of introduction on the cadaver and trained the eye and fingers by practice work on the rubber tube, experience should be had in the living lower air and food passages with their pulsatory, respiratory, bechic and deglutitory movements, and ever-present secretions. it is not only inhuman but impossible to obtain this experience on children. fortunately the dog offers a most ready subject and need in no way be harmed nor pained by this invaluable and life-saving practice. a small dog the size of a terrier (say 6 to 10 pounds in weight) should be chosen and anesthetized by the hypodermic injection of morphin sulphate in dosage of approximately one-sixth of a grain per pound of body weight, given about 45 minutes before the time of practice. dogs stand large doses of morphin without apparent ill effect, so that repeated injection may be given in smaller dosage until the desired degree of relaxation results. the first effect is vomiting which gives an empty stomach for esophagoscopy and gastroscopy. vomiting is soon followed by relaxation and stupor. the dog is normal and hungry in a few hours. dosage must be governed in the clog as in the human being by the susceptibility to the drug and by the temperament of the animal. other forms of anesthesia have been tried in my teaching, and none has proven so safe and satisfactory. phonation may be prevented during esophagoscopy by preventing approximation of the cords, through inserting a silk-woven cathether in the trachea. the larynx and trachea may be painted with cocain solution if it is found necessary for bronchoscopy. a very comfortable and safe mouth gag is shown in fig. 73. great gentleness should be exercised, and no force should be used, for none is required in endoscopic work; and the endoscopist will lose much of the value of his dog practice if he fails to regard the dog as a child. he should remember he is not learning how to do endoscopy on the dog; but learning on the dog how safely to do bronchoscopy on a human being. the degree of resistance during introduction can be gauged and the color of the mucosa studied, while that interesting phenomenon, the dilatation and lengthening of the bronchi during inspiration and their contraction and shortening during expiration, is readily observed and always forms subject for thought in its possible connection with pathological conditions. foreign body problems are now to be solved under these living conditions, and it is my feeling that no one should attempt the removal of a foreign body from the bronchus of a child until he has removed at least 100 foreign bodies from the dog without harming the animal. dogs have the faculty of easily ridding their air-passages of foreign objects, so that one need not be alarmed if a foreign body is lost during practice removal. it is to be remembered that dogs swallow very large objects with apparent ease. the dog's esophagus is relatively much larger than that of human beings. therefore a small dog (of six to eight pounds' weight) must be used for esophagoscopic practice, if practice is to be had with objects of the size usually encountered in human beings. the bronchi of a dog of this weight will be about the size of those of a child. [fig. 73.--author's mouth gag for use on the dog. the thumb-nut serves to prevent an uncomfortable degree of expansion of the gag. a bandage may be wound around the dog's jaws to prevent undue spread of the jaws.] _endoscopy on the human being_.--dog work offers but little practice in laryngoscopy. because of the slight angle at which the dog's head joins his spine, the larynx is in a direct line with the open mouth; hence little displacement of the anterior cervical tissues is necessary. moreover the interior of the larynx of the dog is quite different from that of the human larynx. the technic of laryngoscopy in the human subject is best perfected by a routine direct examination of the larynx of anesthetized patients after such an operation as, for instance, tonsillectomy, to see that the larynx and laryngopharynx are free of clots. to perform a bronchoscopy or esophagoscopy under these conditions would be reprehensible; but direct laryngoscopy for the seeking and removal of clots serves a useful purpose as a preventative of pulmonary abscess and similar complications.* diagnosis of laryngeal conditions in young children is possible only by direct laryngoscopy and is neglected in almost all of the cases. no anesthesia, general or local, is required. much clinical material is neglected. all cases of dyspnea or dysphagia should be studied endoscopically if the cause of the condition cannot be definitely found and treated by other means. invaluable practice in esophagoscopy is found in the treatment of strictures of the esophagus by weekly or biweekly esophagoscopic bouginage. * dr. william frederick moore, of the bronchoscopic clinic, has recently collected statistics of 202 cases of post-tonsillectomic pulmonary abscess that point strongly to aspiration of infected clots and other infective materials as the most frequent etiologic mechanism (moore, w. f., pulmonary abscess. journ. am. med. assn., april 29, 1922, vol. 78, pp. 1279-1281). in acquiring skill as an endoscopist the following paraphrased aphorisms afford food for thought. aphorisms educate your eye and your fingers. be sure you are right, but not too sure. follow your judgment, never your impulse. cry over spilled milk enough to memorize how you spilled it. let your mistakes worry you enough to prevent repetition. let your left hand know what your right hand does and how to do it. nature helps, but she is no more interested in the survival of your patient than in the survival of the attacking pathogenic bacteria. [126] chapter xii--foreign bodies in the air and food passages the air and food passages may be invaded by any foreign substance of solid, liquid or gaseous nature, from the animal, vegetable, or mineral kingdoms. its origin may be from within the body (blood, pus, secretion, broncholiths, sequestra, worms); introduced from without by way of the natural passages (aspirated or swallowed objects); or it may enter by penetration (bullet, dart, drainage tube from the neck). _prophylaxis_.--if one put into his mouth nothing but food, foreign body accidents would be rare. the habit of holding tacks, pins and whatnot in the mouth is quite universal and deplorable. children are prone to follow the bad example of their elders. no small objects such as safety pins, buttons, and coins should be left within a baby's reach; children should be watched and taught not to place things in their mouths. mothers should be specially cautioned not to give nuts or nut candy of any kind to a child whose powers of mastication are imperfect, because the molar teeth are not erupted. it might be made a dictum that: "no child under 3 years of age should be allowed to eat nuts, unless ground finely as in peanut butter." digital efforts at removal of foreign bodies frequently force the object downward, or may hook it forward into the larynx, whereas if not meddled with digitally the intruder might be spat out. before general anesthesia the mouth should be searched for loose teeth, removable dentures, etc., and all unconscious individuals should be likewise examined. when working in the mouth precautions should be taken against the possible inhalation or swallowing of loose objects or instruments. [126] objects that have lodged in the esophagus, larynx, trachea, or bronchi should be endoscopically removed. _foreign bodies in the insane_.--foreign bodies may be introduced voluntarily and in great numbers by the insane. hysterical individuals may assert the presence of a foreign body, or may even volitionally swallow or aspirate objects. it is a mistake to do a bronchoscopy in order to cure by suggestion the delusion of foreign body presence. such "cures" are ephemeral. _foreign bodies in the stomach_.--gastroscopy is indicated in cases of a foreign body that refuses to pass after a month or two. foreign bodies in very large numbers in the stomach, as in the insane, may be removed by gastrostomy. _the symptomatology of foreign bodies_ may be epitomized as given below; but it must be kept in mind, that certain symptoms may not be manifest immediately after intrusion, and others may persist for a time after the passage, removal, or expulsion of a foreign body. esophageal foreign body symptoms 1. there are no absolutely diagnostic symptoms. 2. dysphagia, however, is the most constant complaint, varying with the size of the foreign body, and the degree of inflammatory or spasmodic reaction produced. 3. pain may be caused by penetration of a sharp foreign body, by inflammation secondary thereto, by impaction of a large object, or by spasmodic closure of the hiatus esophageus. 4. the subjective sensation of foreign body is usually present, but cannot be relied upon as assuring the presence of a foreign body for this sensation often remains for a time after the passage onward of the intruder. 5. all of these symptoms may exist, often in the most intense degree, as the result of previous violent attempts at removal; and the foreign body may or may not be present. symptoms of laryngeal foreign body 1. initial laryngeal spasm followed by wheezing respiration, croupy cough, and varying degrees of impairment of phonation. 2. pain may be a symptom. if so, it is usually located in the laryngeal region, though in some cases it is referred to the ears. 3. the larynx may tolerate a thin, flat, foreign body for a relatively long period of time, a month or more; but the development of increasing dyspnea renders early removal imperative in the majority of cases. symptoms of tracheal and bronchial foreign body 1. tracheal foreign bodies are usually movable and their movements can usually be felt by the patient. 2. cough is usually present at once, may disappear for a time and recur, or may be continuous, and may be so violent as to induce vomiting. in recent cases fixed foreign bodies cause little cough; shifting foreign bodies cause violent coughing. 3. sudden shutting off of the expiratory blast and the phonation during paroxysmal cough is almost pathognomonic of a movable tracheal foreign body. 4. dyspnea is usually present in tracheal foreign bodies, and is due to the bulk of the foreign body plus the subglottic swelling caused by the traumatism of the shiftings of the intruder. 5. dyspnea is usually absent in bronchial foreign bodies. 6. the respiratory rate is increased only if a considerable portion of lung is out of function, by the obstruction of a main bronchus, or if inflammatory sequelae are extensive. 7. the asthmatoid wheeze is usually present in tracheal foreign bodies, and is often louder and of lower pitch than the asthmatoid wheeze of bronchial foreign bodies. it is heard at the open mouth, not at the chest wall; and prolonged expiration as though to rid the lungs of all residual air, may be necessary to elicit it. 8. pain is not a common symptom, but may occur and be accurately localized by the patient, in case of either tracheal or bronchial foreign body. early symptoms of irritating foreign body such as a peanut kernel in the bronchus 1. initial laryngeal spasm is almost invariably present with foreign bodies of organic nature, such as nut kernels, peas, beans, maize, etc. 2. a diffuse purulent laryngo-tracheo-bronchitis develops within 24 hours in children under 2 years. 3. fever, toxemia, cyanosis, dyspnea and paroxysmal cough are promptly shown. 4. the child is unable to cough up the thick mucilaginous pus through the swollen larynx and may "drown in its own secretions" unless the offender be removed. 5. "drowned lung," that is to say natural passages idled with pus and secretions, rapidly forms. 6. pulmonary abscess develops sooner than in case of mineral foreign bodies. 7. the older the child the less severe the reaction. symptoms of prolonged foreign body sojourn in the bronchus 1. the time of inhalation of a foreign body may be unknown or forgotten. 2. cough and purulent expectoration ultimately result, although there may be a delusive protracted symptomless interval. [130] 3. periodic attacks of fever, with chills and sweats, and followed by increased coughing and the expulsion of a large amount of purulent, usually more or less foul material, are so nearly diagnostic of foreign body as to call for exclusion of this probability with the utmost care. 4. emaciation, clubbing of the fingers and toes, night sweats, hemoptysis, in fact all of the symptoms of tuberculosis are in most cases simulated with exactitude, even to the gain in weight by an out-door regime. 5. tubercle bacilli have never been found, in the cases at the bronchoscopic clinic, associated with foreign body in the bronchus.* in cases of prolonged sojourn this has been the only element lacking in a complete clinical picture of advanced tuberculosis. one point of difference was the almost invariably rapid recovery after removal of the foreign body. the statement in all of the text-books, that foreign body is followed by phthisis pulmonalis is a relic of the days when the bacillary origin of true tuberculosis was unknown, hence the foreign-body phthisis pulmonalis, or pseudo tuberculosis, was confused with the true pulmonary tuberculosis of bacillary origin. 6. the subjective sensation of pain may allow the patient accurately to localize a foreign body. 7. foreign bodies of metallic or organic nature may cause their peculiar taste in the sputum. 8. offensive odored sputum should always suggest bronchial foreign body; but absence of sputum, odorous or not, should not exclude foreign body. 9. sudden complete obstruction of one main bronchus does not cause noticeable dyspnea provided its fellow is functionating. [131] 10. complete obstruction of a bronchus is followed by rapid onset of symptoms. 11. the physical signs usually show limitation of expansion on the affected side, impairment of percussion, and lessened trans-mission or absence of breath-sounds distal to the foreign body. * the exceptional case has at last been encountered. a boy with a tack in the bronchus was found to have pulmonary tuberculosis. symptoms of gastric foreign body foreign body in the stomach ordinarily produces no symptoms. the roentgenogram and the fluoroscopic study with an opaque mixture are the chief means of diagnosis. diagnosis of foreign body in the air or food passages the questions arising are: i. is a foreign body present? 2. where is it located? 3. is a peroral endoscopic procedure indicated? 4. are there any contraindications to endoscopy? in order to answer these questions the definite routine given below is followed unvaryingly in the bronchoscopic clinic. 1. history. 2. complete physical examination, including mirror laryngoscopy. 3. roentgenologic study. 4. endoscopy. the history should note the date of, and should delve into the details of the accident; special note being made of the occurrence of laryngeal spasm, wheezing respiration heard by the patient or others (asthmatoid wheeze), fever, cough, pain, dyspnea, dysphagia, odynphagia, regurgitation, etc. the amount, character and odor of sputum are important. increasing amounts of purulent, foul-odored, sometimes blood-tinged sputum strongly suggest prolonged bronchial foreign body sojourn. the mode of onset of the persisting symptoms, whether immediately following the supposed accident or delayed in their occurrence, is to be noted. do attacks of sudden dyspnea and cyanosis occur? what has been the previous treatment and what attempts at removal have been made? the nature of the foreign body is to be determined, and if possible a duplicate thereof obtained. _general physical examination_ should be complete including inspection of the eyes, ears, nose, pharynx, and mirror inspection of the naso-pharynx and larynx. special attention is paid to the chest for the localization of the object. in order to discover conditions rendering endoscopy unusually hazardous, all parts of the body are to be examined. aneurysm of the aorta, excessive blood pressure, serious cardiac and renal conditions, the presence of a hernia and the existence of central nervous disease, as tabes dorsalis, should be at least known before attempting any endoscopic procedure. dysphagia might result from the pressure of an unknown aneurysm, the symptoms being attributed to a foreign body, and aortic aneurysm is a definite contraindication to esophagoscopy unless there be foreign body present also. there is no absolute contraindication to the endoscopic removal of a foreign body, though many conditions may render it wise to post-pone endoscopy. laryngeal crises of tabes might, because of their sudden onset, be thought due to foreign body. physical signs in esophageal foreign body there are no constant physical signs associated with uncomplicated impaction of a foreign body in the esophagus. should perforation of the cervical esophagus occur, subcutaneous emphysema, and perhaps cellulitis, may be found; while a perforation of the thoracic region causing mediastinitis is manifested by toxemia, fever, and rapid sinking. perforation of the pleura, with the development of pyopneumothorax, is manifested by the usual signs. it is to be emphasized that blind bouginage has no place in the diagnosis of any esophageal condition. the roentgenologist will give the information we desire without danger to the patient, and with far greater accuracy. foreign bodies in the larynx laryngeally lodged foreign bodies produce a wheezing respiration, the quality of which is peculiar to the larynx and is readily localized to this organ. if swelling or the size of the foreign body be sufficient to produce dyspnea, inspiratory indrawing of the suprasternal notch, supraclavicular fossae, costal interspaces and lower sternum will be present. cyanosis is only an accompaniment of suddenly produced dyspnea; the facies will therefore usually be anxious and pale, unless the patient is seen immediately after the aspiration of the foreign body. if labored breathing has been prolonged, and exhaustion threatened, the heart's action will be irregular and weak. the foreign body can be seen with the mirror, but a roentgenograph must nevertheless be made, for the object may be of another nature than was first thought. the roentgenograph will show its position, and from this knowledge the plan of removal can be formulated. for example, a straight pin may be so placed in the larynx that only a portion of its shaft will be visible, the roentgenogram will tell where the head and point are located, and which of these will be the more readily disengaged. (see chapter on mechanical problems.) physical signs of tracheal foreign body if fixed in the trachea the only objective sign of foreign body may be a wheezing respiration, the site of which may be localized with the stethoscope, by the intensity of the sound. movable foreign bodies may produce a palpatory thrill, and the rumble and sudden stop can be heard with the stethoscope and often with the naked ear. the lungs will show equal aeration, but there may be marked dyspnea without the indrawing of the fossae, if the object be of large size and located below the manubrium. to the peculiar sound of the sudden subglottic, expiratory or bechic arrest of the foreign body the author has given the name "audible slap;" when felt by the thumb on the trachea he calls it the "palpatory thud." these signs can be produced by no condition other than the arrest of some substance by the subglottic taper. once heard and felt they are unmistakable. physical signs of bronchial foreign body in most cases there will be limitation of expansion on the invaded side, even though the foreign body is of such a shape as to cause no bronchial obstruction. it has been noted frequently in conjunction with the presence of such objects as a common straight pin in a small branch bronchus. this peculiar phenomenon was first noted by thomas mccrae in one of the author's cases and has since been abundantly corroborated by mccrae and others as one of the most constant physical signs. to understand the peculiar physical findings in these cases it is necessary to remember that the bronchi are not tubes of constant caliber; there occurs a dilatation during inspiration, and a contraction of the lumen during expiration; furthermore, the lumen may be narrowed by swollen mucosa if the foreign body be of an irritant nature. the signs vary with the degree of obstruction of the bronchus, and with the consequent degree of interference with aeration and drainage of the subjacent portion of the lung. we have three definite types which show practically constant signs in the earlier stages of foreign body invasion. 1. complete bronchial occlusion. 2. obstruction complete during expiration, but allowing the passage of air during the bronchial dilatation incident to inspiration, constituting an expiratory valve-like obstruction. 3. partial bronchial obstruction, allowing to-and-fro passage of air. 1. _complete bronchial obstruction_ is manifested by limitation of expansion, markedly impaired percussion note, particularly at the base, absence of breath-sounds, and rales on the invaded side. an atelectasis here exists; the air imprisoned in the lung is soon absorbed, and secretions rapidly accumulate. on the free side a compensatory emphysema is present. 2. _expiratory valve-like obstruction_.--the obstructed side shows marked limitation of expansion. percussion is of a tympanitic character. the duration of the vibrations may be shortened giving a muffled tympany. various grades and degrees of tympany may be noted. breath sounds are markedly diminished or absent. no rales are heard on the invaded side, although rales of all types may be present on the free side. in some cases it is possible to hear a short inspiratory sound. vocal resonance and fremitus are but little altered. the heart will be found displaced somewhat to the opposite side. these signs are explained by the passage of some air past the foreign body during inspiration with its trapping during expiration, so that there is air under pressure constantly maintained in the obstructed area. this type of obstruction is most frequently observed when the foreign body is of an organic nature such as nut kernels, beans, corn, seed, etc. the localized swelling about the irritating foreign body completes the expiratory obstruction. it may also be present with any foreign body whose size and shape are such as to occlude the lumen of the bronchus during its contracted expiratory phase. it was present in cases of pebbles, cylindrical metallic objects, thick tough balls of secretion etcetera. the valvular action is here produced most often by a change in the size of the valve seat and not by a movement of the foreign body plug. in other cases i have found at bronchoscopy, a regular ball-valve mechanism. pneumothorax is the only pathologic condition associated with signs similar to those of expiratory, valve-like bronchial obstruction by a foreign body. 3. _partial bronchial obstruction_ by an object such as a nail allows air to pass to and fro with some degree of retardation, and impairs the drainage of the subjacent lung. limitation of expansion will be found on the invaded side. the area below the foreign body will give an impaired percussion note. breath-sounds are diminished in the area of dullness, and vocal resonance and fremitus are impaired. rales are of great diagnostic import; the passage of air past the foreign body is accompanied by blowing, harsh breathing, and snoring; snapping rales are heard usually with greatest intensity posteriorly over the site of the foreign body (usually about the scapular angle). a knowledge of the topographical lung anatomy, the bronchial tree, and of endoscopic pathology* should enable the examiner of the chest to locate very accurately a bronchial foreign body by physical signs alone, for all the significant signs occur distal to the foreign body lodgment. * jackson, chevalier. pathology of foreign bodies in the air and food passages. mutter lecture, 1918. surgery, gynecology and obstetrics, march, 1919. also, by the same author, mechanism of the physical signs of foreign bodies in the lungs. proceedings of the college of physicians, philadelphia, 1922. _the asthmatoid wheeze_ has been found by the author a valuable confirmatory sign of bronchial foreign body. it is a wheezing heard by placing the observer's ear at the open mouth of the patient (not at the chest wall) during a prolonged forced expiration. thomas mccrae elicits this sign by placing the stethoscope bell at the patient's open mouth. the quality of the sound is dryer than that heard in asthma and the wheeze is clearest after all secretion has been removed by coughing. the mechanism of production is, probably, the passage of air by a foreign body which narrows the lumen of a large bronchus. as the foreign body works downward the wheeze lessens. the wheeze is often so loud as to be heard at some distance from the patient. it is of greatest value in the diagnosis of non-roentgenopaque foreign body but its absence in no way negates foreign body. its presence or absence should be recorded in every case. _prolonged bronchial obstruction_ by foreign body is followed by bronchiectasis and lung abscess usually in a lower lobe. the symptoms may with exactitude simulate tuberculosis, but this disease should be readily excluded by the basal, unilateral site of the lesion, absence of tubercle bacilli in the sputum, and roentgenographic study. chest examination in the foreign body cases reveals limitation of expansion, often some retraction, flat percussion note, and greatly diminished or absent breath-sounds over the site of the pulmonary lesion. rales vary with the amount of secretion present. these physical signs suggest empyema; and rib resection had been done before admission in a number of cases only to find the pleura normal. roentgenray study in foreign body cases _roentgenography_.--all cases of chest disease should have the benefit of a roentgenologic study to exclude bronchial foreign body as an etiological factor. negative opinions should never be based upon any plates except the best that the wonderful modern development of the art and science of roentgenology can produce. in doubtful cases, the negative opinion should not be conclusive until a roentgenologist of long experience in chest work, and especially in foreign body cases, has been called in consultation. even then there will be an occasional case calling for diagnostic bronchoscopy. antero-posterior and lateral roentgenograms should always be made. in an antero-posterior film a flat foreign body lying in the lateral body plane might be invisible in the shadow of the spine, heart, and great vessels; but would be revealed in the lateral view because of the greater edgewise density of the intruder and the absence of other confusing shadows. fluoroscopic examination will often discover the best angle from which to make a plate; but foreign bodies casting a very faint shadow on a plate may be totally invisible on the fluoroscopic screen. the value of a roentgenogram after the removal of a foreign body cannot be too strongly emphasized. it is evidence of removal and will exclude the presence of a second intruder which might have been overlooked in the first study. fluoroscopic study of the swallowing function with barium mixture, or a barium-filled capsule, will give the location of a nonroentgenopaque object (such as bone, meat, etc.) in the esophagus. if a flat or disc-shaped object located in the cervical region is seen to be lying in the lateral body plane, it will be found to be in the esophagus, for it assumed that position by passing down flatwise behind the larynx. if, however, the object is seen to be in the sagittal plane it must lie in the trachea. this position was necessary for it to pass through the glottic chink, and can be maintained because of the yielding of the posterior membranous wall of the trachea. the roentgenographic signs of expiratory-valve-like bronchial obstruction the roentgenray signs in expiratory valve-like obstruction of a bronchus are those of _an acute obstructive emphysema_ (fig. 74), namely, 1. greater transparency on the obstructed side (iglauer). 2. displacement of the heart to the free side (iglauer). 3. depression and flattening of the dome of the diaphragm on the invaded side (iglauer). 4. limitation of the diaphragmatic excursion on the obstructed side (manges). it is very important to note that, as discovered by manges, the differential emphysema occurs at the end of expiration and the plate must be exposed at that time, before inspiration starts. he also noted that at fluoroscopy the heart moved laterally toward the uninvaded side during expiration.* * dr. manges has developed such a high degree of skill in the fluoroscopic diagnosis of non-opaque foreign bodies by the obstructive emphysema they produce that he has located peanut kernels and other vegetable substances with absolute accuracy and unfailing certainty in dozens of cases at the bronchoscopic clinic. [fig. 74--expiratory valve-like bronchial obstruction by non-radiopaque foreign body, producing an acute obstructive emphysema. peanut kernel in right main bronchus. note (a) depression of right diaphragm; (b) displacement of heart and mediastinum to left; (c) greater transparency of the invaded side. ray-plate made by willis f. manges.] _complete bronchial obstruction_ shows a density over the whole area the aeration and drainage of which has been cut off (fig. 75). pulmonary abscess formation and "drowned lung" (accumulated secretion in the bronchi and bronchioli) are shown by the definite shadows produced (fig. 76). [140] dense and metallic objects will usually be readily seen in the roentgenograms and fluoroscope, but many foreign bodies are of a nature which will produce no shadow; the roentgenologist should, therefore, be prepared to interpret the pulmonary pathology, and should not dismiss the case as negative for foreign body because one is not seen. even metallic objects are in rare cases exceedingly difficult to demonstrate. [fig. 75.--radiograph showing pathology resulting from complete obstruction of a bronchus with atelectasis and drowned lung resulting. foot of an alarm clock in left bronchus of 4 year old child. present 25 days. plate made by johnston and grier.] _positive films of the tracheo-bronchial tree as an aid to localization_.--in order to localize the bronchus invaded by a small foreign body the positive film is laid over the negative of the patient showing the foreign body. the shadow of the foreign body will then show through the overlying positive film. these positive films are made in twelve sizes, and the size selected should be that corresponding to the size of the patient as shown by the roentgenograph. the dome of the diaphragm and the dome of the pleura are taken as visceral landmarks for placing the positive films which have lines indicating these levels. if the shadow of the foreign body be faint it may be strengthened by an ink mark on the uncoated side of the plate.

[143] 3. do not fail to have a roentgenogram made, if possible, whether the foreign body in question is of a kind dense to the ray or not. 4. do not fail to search endoscopically for a foreign body in all cases of doubt. 5. do not pass blindly an esophageal bougie, probang, or other instrument. 6. do not tell the patient he has no foreign body until after roentgenray examination, physical examination, indirect examination, and endoscopy have all proven negative. summary symptomatology and diagnosis of foreign bodies in the air and food passages _initial symptoms_ are choking, gagging, coughing, and wheezing, often followed by a symptomless interval. the foreign body may be in the larynx, trachea, bronchi, nasal chambers, nasopharynx, fauces, tonsil, pharynx, hypopharynx, esophagus, stomach, intestinal canal, or may have been passed by bowel, coughed out or spat out, with or without the knowledge of the patient. initial choking, etcetera may have escaped notice, or may have been forgotten. _laryngeal foreign body_.--one or more of the following laryngeal symptoms may be present: hoarseness, croupy cough, aphonia, odynphagia, hemoptysis, wheezing, dyspnea, cyanosis, apnea, subjective sensation of foreign body. croupiness in foreign body cases, as in diphtheria, usually means subglottic swelling. obstructive foreign body may be quickly fatal by laryngeal impaction on aspiration, or on abortive bechic expulsion. lodgement of a non-obstructive foreign body may be followed by a symptomless interval. direct laryngoscopy for diagnosis is indicated in every child having laryngeal diphtheria without faucial membrane. (no anesthetic, general or local is needed.) in the presence of laryngeal symptoms, think of the following: 1. a foreign body in the larynx. 2. a foreign body loose or fixed in the trachea. 3. digital efforts at removal. 4. instrumentation. 5. overflow of food into the larynx from esophageal obstruction due to the foreign body. 6. esophagotracheal fistula from ulceration set up by a foreign body in the esophagus, followed by the leakage of food into the air-passages. 7. laryngeal symptoms may persist from the trauma of a foreign body that has passed on into the deeper air or food passages or that has been coughed or spat out. 8. laryngeal symptoms (hoarseness, croupiness, etcetera) may be due to digital or instrumental efforts at the removal of a foreign body that never was present. 9. laryngeal symptoms may be due to acute or chronic laryngitis, diphtheria, pertussis, infective laryngotracheitis, and many other diseases. 10. deductive decisions are dangerous. 11. if the roentgenray is negative, laryngoscopy (direct in children, indirect in adults) without anesthesia, general or local, is the only way to make a laryngeal diagnosis. 12. before doing a diagnostic laryngoscopy, preparation should be made for taking a swab-specimen and for bronchoscopy and esophagoscopy. _tracheal foreign body_.--(1) "audible slap," (2) "palpatory thud," and (3) "asthmatoid wheeze" are pathognomonic. the "tracheal flutter" has been observed by mccrae in a case of watermelon seed. cough, hoarseness, dyspnea, and cyanosis are often present. diagnosis is by roentgenray, auscultation, palpation, and bronchoscopy. listen long for "audible slap," best heard at open mouth during cough. the "asthmatoid wheeze" is heard with the ear or stethoscope bell (mccrae) at the patient's open mouth. history of initial choking, gagging, and wheezing is important if elicited, but is valueless negatively. _bronchial foreign body_.--initial symptoms are coughing, choking, asthmatoid wheeze, etc. noted above. there may be a history of these or of tooth extraction. at once, or after a symptomless interval, cough, blood-streaked sputum, metallic taste, or special odor of foreign body may be noted. non-obstructive metallic foreign bodies afford few symptoms and few signs for weeks or months. obstructive foreign bodies cause atelectasis, drowned lung, and eventually pulmonary abscess. lobar pneumonia is an exceedingly rare sequel. vegetable organic foreign bodies as peanut-kernels, beans, watermelon seeds, etcetera, cause at once violent laryngotracheobronchitis, with toxemia, cough and irregular fever, the gravity and severity being inversely to the age of the child. bones, animal shells and inorganic bodies after months or years produce changes which cause chills, fever, sweats, emaciation, clubbed fingers, incurved nails, cough, foul expectoration, hemoptysis, in fact, all the symptoms of chronic pulmonary sepsis, abscess, and bronchiectasis. these symptoms and some of the physical signs may suggest pulmonary tuberculosis, but the apices are normal and bacilli are absent from the sputum. every acute or chronic chest case calls for the exclusion of foreign body. _the physical signs_ vary with conditions present in different cases and at different times in the same case. secretions, normal and pathologic, may shift from one location to another; the foreign body may change its position admitting more, less, or no air, or it may shift to a new location in the same lung or even in the other lung. a recently aspirated pin may produce no signs at all. the signs of diagnostic importance are chiefly those of partial or complete bronchial obstruction, though a non-obstructive foreign body, a pin for instance, may cause limited expansion (mccrae) or, rarely, a peculiar rale or a peculiar auscultatory sound. the most nearly characteristic physical signs are: (1) limited expansion; (2) decreased vocal fremitus; (3) impaired percussion note; (4) diminished intensity of the breath-sounds distal to the foreign body. complete obstruction of a bronchus followed by drowned lung adds absence of vocal resonance and vocal fremitus, thus often leading to an erroneous diagnosis of empyema. varying grades of tympany are obtained over areas of obstructive or compensatory emphysema. with complete obstruction there may be tympany from the collapsed lung for a time. rales in case of complete obstruction are usually most intense on the uninvaded side. in partial obstruction they are most often found on the invaded side distal to the foreign body, especially posteriorly, and are most intense at the site corresponding to that of the foreign body. a foreign body at the bifurcation of the trachea may give signs in both lungs. early in a foreign body case, diminished expansion of one side, with dulness, may suggest pneumonia in the affected side; but absence of, or decreased, vocal resonance, and absence of typical tubular breathing should soon exclude this diagnosis. bronchial obstruction in pneumonia is exceedingly rare. memorize these signs suggestive of foreign body: 1. expansion--diminished. 2. percussion note--impaired (except in obstructive emphysema). 3. vocal fremitus--diminished. 4. breath sounds--diminished. the foregoing is only for memorizing, and must be considered in the light of the following fundamental note by prof. mccrae "there is no one description of physical signs which covers all cases. if the student will remember that complete obstruction of a bronchus leads to a shutting off of this area, there should be little difficulty in understanding the signs present. the diagnosis of empyema may be made, but the outline of the area of dulness, the fact that there is no shifting dulness, and the greater resistance which is present in empyema nearly always clear up any difficulty promptly. the absence of the frequent change in the voice sounds, so significant in an early small empyema, is of value. a large empyema should give no difficulty. if difficulty remains the use of the needle should be sufficient. in thickened pleura vocal fremitus is not entirely absent, and the breath-sounds can usually be heard, even if diminished. in case of partial obstruction of a bronchus, it is evident that air will still be present, hence the dulness may be only slight. the presence of air and secretion will probably result in the breath-sounds being somewhat harsh, and will cause a great variety of rales, principally coarse, and many of them bubbling. difficulty may be caused by signs in the other lung or in a lobe other than the one affected by the foreign body. if it is remembered that these signs are likely to be only on auscultation, and to consist largely in the presence of rales, while the signs in the area supplied by the affected bronchus will include those on inspection, palpation, and percussion, there should be little difficulty." _the roentgenray_ is the most valuable diagnostic means; but careful notation of physical signs by an expert should be made in all cases preferably without knowledge of ray findings. expert ray work will show all metallic foreign bodies and many of less density, such as teeth, bones, shells, buttons, etcetera. if the ray is negative, a diagnostic bronchoscopy should be done in all cases of unexplained bronchial obstruction. peanut kernels and watermelon seeds and, rarely, other foreign bodies in the bronchi produce obstructive emphysema of the invaded side. fluoroscopy shows the diaphragm flattened, depressed and of less excursion on the invaded side; at the end of expiration, the heart and the mediastinal wall move over toward the uninvaded side and the invaded lung becomes less dense than the uninvaded lung, from the trapping of the air by the expiratory, valve-like effect of obliteration of the "forceps spaces" that during inspiration afford air ingress between the foreign body and the swollen bronchial wall. this partial obstruction causes obstructive emphysema, which must be distinguished from compensatory emphysema, in which the ballooning is in the unobstructed lung, because its fellow is wholly out of function through complete "corking" of the main bronchus of the invaded side. _esophageal foreign body_.--after initial choking and gagging, or without these, there may be a subjective sense of a foreign body, constant or, more often, on swallowing. odynphagia and dysphagia or aphagia may or may not be present. pain, sub-sternal or extending to the back is sometimes present. hematemesis and fever may occur from the foreign body or from rough instrumentation. symptoms referable to the air-passages may be present due to: (1) overflow of the secretions on attempts to swallow through the obstructed esophagus; (2) erosion of the foreign body through from the esophagus into the trachea; or (3) trauma inflicted on the larynx during attempts at removal, digital or instrumental, the foreign body still being present or not. diagnosis is by the roentgenray, first without, then, if necessary, with a capsule filled with an opaque mixture. flat objects, like coins, always lie with their greatest diameter in the coronal plane of the body, when in the esophagus; in the sagittal plane, when in the trachea or larynx. lateral, anteroposterior, and sometimes also quartering roentgenograms are necessary. one taken laterally, low down on the neck but clear of the shoulder, will often show a bone or other semiopaque object invisible in the anteroposterior exposure. [149] chapter xiii--foreign bodies in the larynx and tracheobronchial tree the protective reflexes preventing the entrance of foreign bodies into the lower air passages are: (1) the laryngeal closing reflex and (2) the bechic reflex. laryngeal closing for normal swallowing consists chiefly in the tilting and the closure of the upper laryngeal orifice. the ventricular bands help but slightly; and the epiglottis and the vocal cords little, if at all. the gauntlet to be run by foreign bodies entering the tracheobronchial tree is composed of: 1. epiglottis. 2. upper laryngeal orifice. 3. ventricular bands. 4. vocal cords. 5. bechic blast. the epiglottis acts somewhat as a fender. the superior laryngeal aperture, composed of a pair of movable ridges of tissue, has almost a sphincteric action, in addition to a tilting movement. the ventricular bands can approximate under powerful stimuli. the vocal cords act similarly. the one defect in the efficiency of this barrier, is the tendency to take a deep inspiration preparatory to the cough excited by the contact of a foreign body. _site of lodgment_.--the majority of foreign bodies in the air passages occur in children. the right bronchus is more frequently invaded than the left because of the following factors: i. its greater diameter. 2. its lesser angle of deviation from the tracheal axis. 3. the situation of the carina to the left of the mid-line of the trachea. 4. the action of the trachealis muscle. 5. the greater volume of air going into the right bronchus on inspiration. the middle lobe bronchus is rarely invaded by foreign body, and, fortunately, in less than one per cent of the cases is the object in an upper lobe bronchus. _spontaneous expulsion of foreign bodies from the air passages_. a large, light, foreign body in the larynx or trachea may occasionally be coughed out, but the frequent newspaper accounts of the sudden death of children known to have aspirated objects should teach us never to wait for this occurrence. the cause of death in these cases is usually the impaction of a large foreign body in the glottis producing sudden asphyxiation, and in a certain proportion of these cases the impaction has occurred on the reverse journey, when cough forced the intruder upward from below. the danger of subglottic impaction renders it imperative that attempts to aid spontaneous expulsion by inverting the patient should be discouraged. sharp objects, such as pins, are rarely coughed out. the tendency of all foreign bodies is to migrate down and out to the periphery as their size and shape will allow. most of the reported cases of bechic expulsion of bronchially lodged foreign bodies have occurred after a prolonged sojourn of the object, associated which much lung pathology; and in some cases the object has been carried out along with an accumulation of pus suddenly liberated from an abscess cavity, and expelled by cough. this is a rare sequence compared to the usual formation of fibrous stricture above the foreign body that prevents the possibility of bechic expulsion. to delay bronchoscopy with the hope of such a solution of the problem is comparable to the former dependence on nature for the cure of appendiceal abscess. we do our full duty when we tell the patient or parents that while the foreign body may be coughed up, it is very dangerous to wait; and, further, that the difficulty of removal usually increases with the time the foreign body is allowed to remain in the air passages. _mortality and morbidity of bronchoscopy_ vary directly with the degree of skill and experience of the operator, and the conditions for which the endoscopies are performed. the simple insertion of the bronchoscope is devoid of harm if carefully done. the danger lies in misdirected efforts at removal of the intruder and in repeating bronchoscopies in children at too frequent intervals, or in prolonging the procedure unduly. in children under one year endoscopy should be limited to twenty minutes, and should not be repeated sooner than one week after, unless urgently indicated. a child of 5 years will bear 40 to 60 minutes work, while the adult offers no unvarying time limit. more can be ultimately accomplished, and less reaction will follow short endoscopies repeated at proper intervals than in one long procedure. _indications for bronchoscopy for suspected foreign body_ may be thus summarized: 1. the appearance of a suspicious shadow in the radiograph, in the line of a bronchus. 2. in any case in which lung symptoms followed a clear history of the patient having choked on a foreign body. 3. in any case showing signs of obstruction in the trachea or of a bronchus. 4. in suspected bronchiectasis. 5. symptoms of pulmonary tuberculosis with sputum constantly negative for tubercle bacilli. if the physical signs are at the base, particularly the right base, the indication becomes very strong even in the absence of any foreign body circumstance in the history. 6. in all cases of doubt, bronchoscopy should be done anyway. there is no absolute _contraindication to bronchoscopy for foreign bodies_. extreme exhaustion or reaction from previous efforts at removal may call for delay for recuperation, but pulmonary abscess and even the rarer complications, bronchopneumonia and gangrene of the lung, are improved by the early removal of the foreign body. _choice of time to do bronchoscopy for foreign body_.--the difficulties of removal usually increase from the time of aspiration of the object. it tends to work downward and outward, while the mucosa becomes edematous, partly closing over the foreign body, and even completely obliterating the lumen of smaller bronchi. later, granulation tissue and the formation of stricture further hide the object. the patient's health deteriorates with the onset of pulmonary pathology, and renders him a less favorable subject for bronchoscopy. organic foreign bodies, which produce early and intense inflammatory reaction and are liable to swell, call for prompt bronchoscopy. when a bronchus is completely obstructed by the bulk of the foreign body itself immediate removal is urgently demanded to prevent serious lung changes, resulting from atelectasis and want of drainage. in short, removal of the foreign body should be accomplished as soon as possible after its entrance. this, however, does not justify hasty, ill-planned, and poorly equipped bronchoscopy, which in most cases is doomed to failure in removal of the object. the bronchoscopist should not permit himself to be stampeded into a bronchoscopy late at night, when he is fatigued after a hard day's work. _bronchoscopic finding of a foreign body_ is not especially difficult if the aspiration has been recent. if secondary processes have developed, or the object be small and in a bronchus too small to admit the tube-mouth, considerable experience may be necessary to discover it. there is usually inflammatory reaction around the orifice of the invaded bronchus, which in a measure serves to localize the intruder. we must not forget, however, that objects may have moved to another location, and also that the irritation may have been the result of previous efforts at removal. care must be exercised not to mistake the sharp, shining, interbronchial spurs for bright thin objects like new pins just aspirated; after a few days pins become blackened. if these spurs be torn pneumothorax may ensue. if a number of small bronchi are to be searched, the bronchoscope must be brought into the line of the axis of the bronchus to be examined, and any intervening tissue gently pushed aside with the lip of the bronchoscope. blind probing for exploration is very dangerous unless carefully done. the straight forceps, introduced closed, form the best probe and are ready for grasping if the object is felt. once the bronchoscope has been introduced, it should not be withdrawn until the procedure is completed. the light carrier alone may be removed from its canal if the illumination be faulty. complications and after-effects of bronchoscopy all foreign body cases should be watched day and night by special nurses until all danger of complications is passed. complications are rare after careful work, but if they do occur, they may require immediate attention. this applies especially to the subglottic edema associated with arachidic bronchitis in children under 2 years of age. _general reaction_.--there is usually no elevation in temperature following a short bronchoscopy for the removal of a recently lodged metallic foreign body. if, however, an inflammatory condition of the bronchi existed previous to the bronchoscopy, as for instance the intense diffuse, purulent laryngotracheobronchitis associated with the aspiration of nut kernels, or in the presence of pulmonary abscess from long retained foreign bodies, a moderate temporary rise of temperature may be expected. these cases almost always have had irregular fever before bronchoscopy. disturbance of the epithelium in the presence of pus without abscess usually permits enough absorption to elevate the temperature slightly for a few days. _surgical shock_ in its true form has never followed a carefully performed and time-limited bronchoscopy. severe fatigue resulting in deep sleep may be seen in children after prolonged work. _local reaction_ is ordinarily noted by slight laryngeal congestion causing some hoarseness and disappearing in a few days. if dyspnea occur it is usually due to (1) drowning of the patient in his own secretions. (2) subglottic edema. (3) laryngeal edema. _drowning of the patient in his own secretions_.--the accumulation of secretions in the bronchi due to faulty bechic powers and seen most frequently in children, is quickly relievable by bronchoscopic sponge-pumping or aspiration through the tracheotomic wound, in cases in which the tracheotomy may be deemed necessary. in other cases, the aspirating bronchoscope with side drainage canal (fig. 1, e) may be used through the larynx. frequent peroral passage of the bronchoscope for this purpose is contraindicated only in case of children under 3 years of age, because of the likelihood of provoking subglottic edema. in such cases instead of inserting a bronchoscope the aspirating tube (fig. 9) should be inserted through the direct laryngoscope, or a low tracheotomy should be done. _supraglottic edema_ is rarely responsible for dyspnea except when associated with advanced nephritis. _subglottic edema_ is a complication rarely seen except in children under 3 years of age. they have a peculiar histologic structure in this region, as is shown by logan turner. even at the predisposing age subglottic edema is a very unusual sequence to bronchoscopy if this region was previously normal. the passage of a bronchoscope through an already inflamed subglottic area is liable to be followed by a temporary increase in the swelling. if the foreign body be associated with but slight amount of secretion, the child can usually obtain sufficient air through the temporarily narrowed lumen. if, however, as in cases of arachidic bronchitis, large amounts of purulent secretion must be expelled, it will be found in certain cases that the decreased glottic lumen and impaired laryngeal motility will render tracheotomy necessary to drain the lungs and prevent drowning in the retained secretions. subglottic edema occurring in a previously normal larynx may result from: 1. the use of over-sized tubes. 2. prolonged bronchoscopy. 3. faulty position of the patient, the axis of the tube not being in that of the trachea. 4. trauma from undue force or improper direction in the insertion of the bronchoscope. 5. the manipulation of instruments. 6. trauma inflicted in the extraction of the foreign body. _diagnosis_ must be made without waiting for cyanosis which may never appear. pallor, restlessness, startled awakening after a few minutes sleep, occurring in a child with croupy cough, indrawing around the clavicles, in the intercostal spaces, at the suprasternal notch and at the epigastrium, call for tracheotomy which should always be low. such a case should not be left unwatched. the child will become exhausted in its fight for air and will give up and die. the respiratory rate naturally increases because of air hunger, accumulating secretions that cannot be expelled because of impaired glottic motility give signs wrongly interpreted as pneumonia. many children whose lives could have been saved by tracheotomy have died under this erroneous diagnosis. _treatment_.--intubation is not so safe because the secretions cannot easily be expelled through the tube and postintubational stenosis may be produced. low tracheotomy, the tracheal incision always below the second ring, is the safest and best method of treatment. [156] chapter xiv--removal of foreign bodies from the larynx _symptoms and diagnosis_.--the history of a sudden choking attack followed by impairment of voice, wheezing, and more or less dyspnea can be usually elicited. laryngeal diphtheria is the condition most frequently thought of when these symptoms are present, and antitoxin is rightly given while waiting for a positive diagnosis. extreme dyspnea may render tracheotomy urgently demanded before any attempts at diagnosis are made. further consideration of the symptomatology and diagnosis of laryngeal foreign body will be found on pages 128, 133 and 143. _preliminary examination_.--in the adult, mirror examination of the larynx should be done, the patient being placed in the recumbent position. whenever time permits roentgenograms, lateral and anteroposterior, should be made, the lateral one as low in the neck as possible. one might think this an unnecessary procedure because of the visibility of the larynx in the mirror; but a child's larynx cannot usually be indirectly examined, and even in the adult a pin may be so situated that neither head nor point is visible, only a portion of the shaft being seen. the roentgenogram will give accurate information as to the position, and will thus allow a planning of the best method for removal of the foreign body. a bone in the larynx usually is visible in a good roentgenogram. accurate diagnosis in children is made by direct laryngoscopy without anesthesia, but direct laryngoscopy should not be done until one is prepared to remove a foreign body if found, to follow it into the bronchus and remove it if it should be dislodged and aspirated, and to do tracheotomy if sudden respiratory arrest occur. [157] _technic of removal of foreign bodies from the larynx_.--the patient is to be placed in the author's position, shown in fig. 53. no general anesthesia should be given, and the application of local anesthesia is usually unnecessary and further, is liable to dislodge and push down the foreign body.* because of the risk of loss downward it is best to seize the foreign body as soon as seen; then to determine how best to disimpact it. the fundamental principles are that a pointed object must either have its point protected by the forceps grasp or be brought out point trailing, and that a flat object must be so rotated that its plane corresponds to the sagittal plane of the glottic chink. the laryngeal grasping forceps (fig. 53) will be found the most useful, although the alligator rotation forceps (fig. 31) may occasionally be required. * in adolescents or adults a few drops of a 4 per cent solution of cocain applied to the laryngopharynx with an atomizer or a dropper will afford the minimum risk of dislodgement; but the author's personal preference is for no anesthesia, general or local. [158] chapter xv--mechanical problems of bronchoscopic foreign body extraction* * for more extensive consideration of mechanical problems than is here possible the reader is referred to the bibliography, page 311, especially reference numbers 1, 11, 37 and 56. the endoscopic extraction of a foreign body is a mechanical problem pure and simple, and must be studied from this viewpoint. hasty, ill-equipped, ill-planned, or violent endoscopy on the erroneous principle that if not immediately removed the foreign body will be fatal, is never justifiable. while the lodgement of an organic foreign body (such as a nut kernel) in the bronchus calls for prompt removal and might be included under the list of emergency operations, time is always available for complete preparation, for thorough study of the patient, and localization of the intruder. the patient is better off with the foreign body in the lung than if in its removal a mediastinitis, rupture into the pleura, or tearing of a thoracic blood vessel has resulted. the motto of the endoscopist should be "i will do no harm." if no harm be inflicted, any number of bronchoscopies can be done at suitable intervals, and eventually success will be achieved, whereas if mortality results, all opportunity ceases. the first step in the solution of the mechanical problem is the study of the roentgenograms made in at least three planes; (1) anteroposterior, (2) lateral, and (3) the plane corresponding to the greatest plane of the foreign body. the next step is to put a duplicate of the foreign body into the rubber-tube manikin previously referred to, and try to simulate the probable position shown by the ray, so as to get an idea of the bronchoscopic appearance of the probable presentation. then the duplicate foreign body is turned into as many different positions as possible, so as to educate the eye to assist in the comprehension of the largest possible number of presentations that may be encountered at the bronchoscopy on the patient. for each of these presentations a method of disimpaction, disengagement, disentanglement or version and seizure is worked out, according to the kind of foreign body. prepared by this practice and the radiographic study, the bronchoscope is introduced into the patient. the location of the foreign body is approached slowly and carefully to avoid overriding or displacement. a _study of the presentation_ is as necessary for the bronchoscopist as for the obstetrician. it should be made with a view to determining the following points: 1. the relation of the presenting part to the surrounding tissues. 2. the probable position of the unseen portion, as determined by the appearance of the presenting part taken in connection with the knowledge obtained by the previous ray study, and by inspection of the ray plate upside down on view in front of the bronchoscopist. 3. the version or other manipulation necessary to convert an unfavorable into a favorable presentation for grasping and disengagement. 4. the best instruments to use, and which to use first, as, hook, pincloser, forceps, etc. 5. the presence and position of the "forceps spaces" of which there must be two for all ordinary forceps, one for each jaw, or the "insertion space" for any other instrument. until all of these points are determined it is a grave error to insert any kind of instrument. if possible even swabbing of the foreign body should be avoided by swabbing out the bronchus, when necessary, before the region of the intruder is reached. when the operator has determined the instrument to be used, and the method of using it, the instrument is cautiously inserted, under guidance of the eye. [160] _the lip of the bronchoscope_ is one of the most valuable aids in the solution of foreign-body problems. with it partial or complete version of an object can be accomplished so as to convert an unfavorable presentation into one favorable for grasping with the forceps; edematous mucosa may be displaced, angles straightened and space made at the side of the foreign body for the forceps' jaw. it forms a shield or protector that can be slipped under the point of a sharp foreign body and can make counterpressure on the tissues while the forceps are disembedding the point of the foreign body. with the bronchoscopic lip and the forceps or other instrument inserted through the tube, the bronchoscopist has bimanual, eye-guided control, which if it has been sufficiently practiced to afford the facility in coordinate use common to everyone with knife and fork, will accomplish maneuvers that seem marvelous to anyone who has not developed facility in this coordinate use of the bronchoscopic instruments. _the relation of the tube mouth and foreign body_ is of vital importance. generally considered, the tube mouth should be as near the foreign body as possible, and the object must be placed in the center of the bronchoscopic field, so that the ends of the open jaws of the forceps will pass sufficiently far over the object. but little lateral control is had of the long instruments inserted through the tube; sidewise motion is obtained by a shifting of the end of the bronchoscope. when the foreign body has been centered in the bronchoscopic field and placed in a position favorable for grasping, it is important that this position be maintained by anchoring the tube to the upper teeth with the left, third, and fourth fingers hooked over the patient's upper alveolus (fig. 63) _the light reflex on the forceps_.--it is often difficult for the beginner to judge to what depth an instrument has been inserted through the tube. on slowly inserting a forceps through the tube, as the blades come opposite the distal light they will appear brightly illuminated; or should the blades lie close to the light bulb, a shadow will be seen in the previously brilliantly lighted opposite wall. it is then known that the forceps are at the tube mouth, and the endoscopist has but to gauge the distance from this to the foreign body. this assistance in gauging depth is one of the great advances in foreign body bronchoscopy obtained by the development of distal illumination. _hooks_ are useful in the solution of various mechanical problems, and may be turned by the operator himself into various shapes by heating small probe-pointed steel rods in a spirit lamp, the proximal end being turned over at a right angle for a controlling handle. hooks with a greater curve than a right angle are prone to engage in small orifices from which they are with difficulty removed. a right angle curve of the distal end is usually sufficient, and a corkscrew spiral is often advantageous, rendering removal easy by a reversal of the twisting motion (bib. 11, p. 311). _the use of forceps in endoscopic foreign body extraction_.--two different strengths of forceps are supplied, as will be seen in the list in chapter 1. the regular forceps have a powerful grasp and are used on dense foreign bodies which require considerable pressure on the object to prevent the forceps from slipping off. for more delicate manipulation, and particularly for friable foreign bodies, the lighter forceps are used. spring-opposed forceps render any delicacy of touch impossible. forceps are to be held in the right hand, the thumb in one ring, and the third, or ring finger, in the other ring. these fingers are used to open and close the forceps, while all traction is to be made by the right index finger, which has its position on the forceps handle near the stylet, as shown in fig. 78. it is absolutely essential for accurate work, that the forceps jaws be seen to close upon the foreign body. the impulse to seize the object as soon as it is discovered must be strongly resisted. a careful study of its size, shape, and position and relation to surrounding structures must be made before any attempt at extraction. the most favorable point and position for grasping having been obtained, the closed forceps are inserted through the bronchoscope, the light reflex obtained, the forceps blades now opened are turned in such a position that, on advancing, the foreign body will enter the open v, a sufficient distance to afford a good grasp. the blades are then closed and the foreign body is drawn against the tube mouth. few foreign bodies are sufficiently small to allow withdrawal through the tube, so that tube, forceps and foreign body are usually withdrawn together. [fig. 78.--proper hold of forceps. the right thumb and third fingers are inserted into the rings while the right index finger has its place high on the handle. all traction is made with the index finger, the ring fingers being used only to open and close the forceps. if any pushing is deemed safe it may be done by placing the index finger back of the thumb-nut on the stylet.] _anchoring the foreign body against the tube mouth_.--if withdrawal be made a bimanual procedure it is almost certain that the foreign body will trail a centimeter or more beyond the tube mouth, and that the closure of the glottic chink as soon as the distal end of the bronchoscope emerges will strip the foreign body from the forceps grasp, when the foreign body reaches the cords. this is avoided by anchoring the foreign body against the tube mouth as soon as the foreign body is grasped, as shown in fig. 79. the left index finger and thumb grasp the shaft of the forceps close to the ocular end of the tube, while the other fingers encircle the tube; closure of the forceps is maintained by the fingers of the right hand, while all traction for withdrawal is made with the left hand, which firmly clamps forceps and bronchoscope as one piece. thus the three units are brought out as one; the bronchoscope keeping the cords apart until the foreign body has entered the glottis. [fig. 79--method of anchoring the foreign body against the tube mouth after the object has been drawn firmly against the lip of the endoscopic tube the left finger and thumb grasp the forceps cannula and lock it against the ocular end of the tube, the other fingers of the left hand encircle the tube. withdrawal is then done with the left hand; the fingers of the right hand maintaining closure of the forceps.] [164] _bringing the foreign body through the glottis_.--stripping of the foreign body from the forceps at the glottis may be due to: 1. not keeping the object against the tube mouth as just mentioned. 2. not bringing the greatest diameter of the foreign body into the sagittal plane of the glottic chink. 3. faulty application of the forceps on the foreign body. 4. mechanically imperfect forceps. should the foreign body be lost at the glottis it may, if large become impacted and threaten asphyxia. prompt insertion of the laryngoscope will usually allow removal of the object by means of the laryngeal grasping forceps. the object may be dropped or expelled into the pharynx and be swallowed. it may even be coughed into the naso-pharynx or it may be re-aspirated. in the latter event the bronchoscope is to be re-inserted and the trachea carefully searched. care must be used not to override the object. if much inflammatory reaction has occurred in the first invaded bronchus, temporarily suspending the aerating function of the corresponding lung, reaspiration of a dislodged foreign body is liable to carry it into the opposite main bronchus, by reason of the greater inspiratory volume of air entering that side. this may produce sudden death by blocking the only aerating organ. _extraction of pins, needles and similar long pointed objects_.--when searching for such objects especial care must be taken not to override them. pins are almost always found point upward, and the dictum can therefore be made, "search not for the pin, but for the point of the pin." if the point be found free, it should be worked into the lumen of the bronchoscope by manipulation with the lip of the tube. it may then be seized with the forceps and withdrawn. should the pin be grasped by the shaft, it is almost certain to turn crosswise of the tube mouth, where one pull may cause the point to perforate, enormously increasing the difficulties by transfixation, and perhaps resulting fatally (fig. 80). [fig. 80.--schematic illustration of a serious phase of the error of hastily seizing a transfixed pin near its middle, when first seen as at m. traction with the forceps in the direction of the dart in schema b will rip open the esophagus or bronchus inflicting fatal trauma, and probably the pin will be stripped off at the glottic or the cricopharyngeal level, respectively. the point of the pin must be disembedded and gotten into the tube mouth as at a, to make forceps traction safe.] [fig. 81.--schema illustrating the mechanical problem of extracting a pin, a large part of whose shaft is buried in the bronchial wall, b. the pin must be pushed downward and if the orifice of the branches, c, d, are too small to admit the head of the pin some other orifice (as at a) must be found by palpation (not by violent pushing) to admit the head, so that the pin can be pushed downward permitting the point to emerge (e). the point is then manipulated into the bronchoscopic tube-mouth by means of co-ordinated movements of the bronchoscopic lip and the side-curved forceps, as shown at f.] _inward rotation method_.--when the point is found to be buried in the mucosa, the best and usually successful method is to grasp the pin as near the point as possible with the side-grasping forceps, then with a spiral motion to push the pin downward while rotating the forceps about ninety degrees. the point is thus disengaged, and the shaft of the pin is brought parallel with that of the forceps, after which the point may be drawn into the tube mouth. the lips added to the side-curved forceps by my assistant dr. gabriel tucker i now use exclusively for this inward rotation method. they are invaluable in preventing the escape of the pin during the manipulation. a hook is sometimes useful in disengaging a buried point. the method of its use is illustrated in fig. 82. [fig. 82.--mechanical problem of pin, needle, tack or nail with embedded point. if the forceps are pulled upon the pin point will be buried still deeper. the side curved forceps grasp the pin as near the point as possible then with a corkscrew motion the pin is pushed downward and rotated to the right when the pin will be found to be parallel with the shaft of the forceps and can be drawn into the tube. if the pin is prevented by its head from being pushed downward the point may be extracted by the hook as shown above the side curved forceps may be used instead of the hook for freeing the point, the author's "inward rotation" method. the very best instrument for the purpose is the forceps devised by my assistant, dr. gabriel tucker (fig. 21). the lips prevent all risk of losing the pin from the grasp, and at the same time bring the long axis of the pin parallel to that of the bronchoscope.] pins are very prone to drop into the smaller bronchi and disappear completely from the ordinary field of endoscopic exploration. at other times, pins not dropping so deeply may show the point only during expiration or cough, at which times the bronchi are shortened. in such instances the invaded bronchial orifice should be clearly exposed as near the axis of its lumen as possible; the forceps are now inserted, opened, and the next emergence watched for, the point being grasped as soon as seen. _extraction of tacks, nails and large headed foreign bodies from the tracheobronchial tree_.--in cases of this sort the point presents the same difficulty and requires solution in the same manner as mentioned in the preceding paragraphs on the extraction of pins. the author's inward-rotation method when executed with the tucker forceps is ideal. the large head, however, presents a special problem because of its tendency to act as a mushroom anchor when buried in swollen mucosa or in a fibrous stenosis (fig. 83). the extraction problems of tacks are illustrated in figs. 84, 85, and 86. nails, stick pins, and various tacks are dealt with in the same manner by the author's "inward rotation" method. _hollow metallic bodies_ presenting an opening toward the observer may be removed with a grooved expansile forceps as shown in figs 23 and 25, or its edge may be grasped by the regular side-grasping forceps. the latter hold is apt to be very dangerous because of the trauma inflicted by the catching of the free edge opposite the forceps; but with care it is the best method. should the closed end be uppermost, however, it may be necessary to insert a hook beyond the object, and to coax it upward to a point where it may be turned for grasping and removal with forceps. [fig. 83.--"mushroom anchor" problem of the upholstery tack. if the tack has not been _in situ_ more than a few weeks the stenosis at the level of the darts is simply edematous mucosa and the tack can be pulled through with no more than slight mucosal trauma, _provided_ axis-traction only be used. if the tack has been in situ a year or more the fibrous stricture may need dilatation with the divulsor. otherwise traction may rupture the bronchial wall. the stenotic tissue in cases of a few months' sojourn maybe composed of granulations, in which case axis-traction will safely withdraw it. the point of a tack rarely projects freely into the lumen as here shown. more often it is buried in the wall.] [168] [fig. 84.-schema illustrating the "mushroom anchor" problem of the brass headed upholstery tack. at a the tack is shown with the head bedded in swollen mucosa. the bronchoscopist, looking through the bronchoscope, e, considering himself lucky to have found the point of the tack, seizes it and starts to withdraw it, making traction as shown by the dart in drawing b. the head of the tack catches below a chondrial ring and rips in, tearing its way through the bronchial wall (d) causing death by mediastinal emphysema. this accident is still more likely to occur if, as often happens, the tack-head is lodged in the orifice of the upper lobe bronchus, f. but if the bronchoscopist swings the patient's head far to the opposite side and makes axis-traction, as shown at c, the head of the tack can be drawn through the swollen mucosa without anchoring itself in a cartilage. if necessary, in addition, the lip of the bronchoscope can be used to repress the angle, h, and the swollen mucosa, h. if the swollen mucosa, h, has been replaced by fibrous tissue from many months' sojourn of the tack, the stenosis may require dilatation with the divulsor.] [fig. 85.--problem of the upholstery tack with buried point. if pulled upon, the imminent perforation of the mediastinum, as shown at a will be completed, the bronchus will be torn and death will follow even if the tack be removed, which is of doubtful possibility. the proper method is gently to close the side curved forceps on the shank of the tack near the head, push downward as shown by the dart, in b, until the point emerges. then the forceps are rotated to bring the point of the tack away from the bronchial wall.] [169] _removal of open safety pins from the trachea and bronchi_.-removal of a closed safety pin presents no difficulty if it is grasped at one or the other end. a grasp in the middle produces a "toggle and ring" action which would prevent extraction. when the safety pin is _open with the point downward_ care must be exercised not to override it with the bronchoscope or to push the point through the wall. the spring or near end is to be grasped with the side-curved or the rotation forceps (figs. 19, 20 and 31) and pulled into the bronchoscope, thus closing the pin. an open safety pin lodged point up presents an entirely different and a very difficult problem. if traction is made without closing the pin or protecting the point severe and probably fatal trauma will be produced. the pin may be closed with the pin-closer as illustrated in fig. 37, and then removed with forceps. arrowsmith's pin-closer is excellent. another method (fig. 87) consists in bringing the point of the safety pin into the bronchoscope, after disengaging the point with the side curved forceps, by the author's "inward rotation" method. the forceps-jaws (fig. 21) devised recently by my assistant, dr. gabriel tucker, are ideal for this maneuver. as the point is now protected, the spring, seen just off the tube mouth, is best grasped with the rotation forceps, which afford the securest hold. the keeper and its shaft are outside the bronchoscope, but its rounded portion is uppermost and will glide over the tissues without trauma upon careful withdrawal of the tube and safety pin. care must be taken to rotate the pin so that it lies in the sagittal plane of the glottis with the keeper placed posteriorly, for the reason that the base of the glottic triangle is posterior, and that the posterior wall of the larynx is membranous above the cricoid cartilage, and will yield. a small safety-pin may be removed by version, the point being turned into a branch bronchial orifice. no one should think of attempting the extraction of a safety pin lodged point upward without having practiced for at least a hundred hours on the rubber tube manikin. this practice should be carried out by anyone expecting to do endoscopy, because it affords excellent education of the eye and the fingers in the endoscopic manipulation of any kind of foreign body. then, when a safety pin case is encountered, the bronchoscopist will be prepared to cope with its difficulties, and he will be able to determine which of the methods will be best suited to his personal equation in the particular case. [fig. 86.--schema illustrating the "upper-lobe-bronchus problem," combined with the "mushroom-anchor" problem and the author's method for their solution. the patient being recumbent, the bronchoscopist looking down the right main bronchus, m, sees the point of the tack projecting from the right upper-lobe-bronchus, a. he seizes the point with the side-curved forceps; then slides down the bronchoscope to the position shown dotted at b. next he pushes the bronchoscopic tube-mouth downward and medianward, simultaneously moving the patient's head to the right, thus swinging the bronchoscopic level on its fulcrum, and dragging the tack downward and inward out of its bed, to the position, 1). traction, as shown at c, will then safely and easily withdraw the tack. a very small bronchoscope is essential. the lip of the bronchoscopic tube-mouth must be used to pry the forceps down and over, and the lip must be brought close to the tack just before the prying-pushing movement. s, right stem-bronchus.] [fig. 87.--one method of dealing with an open safety pin without closing it.] _removal of double pointed tacks_.--if the tack or staple be small, and lodged in a relatively large trachea a version may be done. that is, the staple may be turned over with the hook or rotation forceps and brought out with the points trailing. with a long staple in a child's trachea the best method is to "coax" the intruder along gently under ocular guidance, never making traction enough to bury the point deeply, and lifting the point with the hook whenever it shows any inclination to enter the wall. great care and dexterity are required to get the intruder through the glottis. in certain locations, one or both points may be turned into branch bronchi as illustrated in fig. 88, or over the carina into the opposite main bronchus. another method is to get both points into the tube-mouth. this may be favored, as demonstrated by my assistant, dr. gabriel tucker, by tilting the staple so as to get both points into the longest diameter of the tube-mouth. in some cases i have squeezed the bronchoscope in a vise to create an oval tube-mouth. in other cases i have used expanding forceps with grooved blades. [fig. 88.-schema illustrating podalic version of bronchially-lodged staples or double-pointed tacks. h, bronchoscope. a, swollen mucosa covering points of staple. at e the staple has been manipulated upward with bronchoscopic lip and hooks until the points are opposite the branch bronchial orifices, b, c. traction being made in the direction of the dart (f), by means of the rotation forceps, and counterpressure being made with the bronchoscopic lip on the points of the staple, the points enter the branch bronchi and permit the staple to be turned over and removed with points trailing harmlessly behind (k).] _the extraction of tightly fitting foreign bodies from the bronchi. annular edema_.--such objects as marbles, pebbles, corks, etc., are drawn deeply and with force by the inspiratory blast into the smallest bronchus they can enter. the air distal to the impacted foreign body is soon absorbed, and the negative pressure thus produced increases the impaction. a ring of edematous mucosa quickly forms and covers the presenting part of the object, leaving visible only a small surface in the center of an acute edematous stenosis. a forceps with narrow, stiff, expansive-spring jaws may press back a portion of the edema and may allow a grasp on the sides of the foreign body; but usually the attempt to apply forceps when there are no spaces between the presenting part of the foreign body and the bronchial wall, will result only in pushing the foreign body deeper.* a better method is to use the lip of the bronchoscope to press back the swollen mucosa at one point, so that a hook may be introduced below the foreign body, which then can be worked up to a wider place where forceps may be applied (fig. 89). sometimes the object may even be held firmly against the tube mouth with the hook and thus extracted. for this the unslanted tube-mouth is used. * the author's new ball forceps are very successful with ball-bearing balls and marbles. [fig. 89.--schema illustrating the use of the lip of the bronchoscope in disimpaction of foreign bodies. a and b show an annular edema above the foreign body, f. at c the edematous mucosa is being repressed by the lip of the tube mouth, permitting insinuation of the hook, h, past one side of the foreign body, which is then withdrawn to a convenient place for application of the forceps. this repression by the lip is often used for purposes other than the insertion of hooks. the lip of the esophagoscope can be used in the same way.] _extraction of soft friable foreign bodies from the tracheobronchial tree_.--the difficulties here consist in the liability of crushing or fragmenting the object, and scattering portions into minute bronchi, as well as the problem of disimpaction from a ring of annular edema, with little or no forceps space. there is usually in these cases an abundance of purulent secretion which further hinders the work. the great danger of pushing the foreign body downward so that the swollen mucosa hides it completely from view, must always be kept in mind. extremely delicate forceps with rather broad blades are required for this work. the fenestrated "peanut" forceps are best for large pieces in the large bronchi. the operator should develop his tactile sense with forceps by repeated practice in order to acquire the skill to grasp peanut kernels sufficiently firmly to hold them during withdrawal, yet not so firmly as to crush them. nipping off an edge by not inserting the forceps far enough is also to be avoided. small fragments under 2 mm. in diameter may be expelled with the secretions and fragments may be found on the sponges and in the secretions aspirated or removed by sponge pumping. it is, however, never justifiable deliberately to break a friable foreign body with the hope that the fragments will be expelled, for these may be aspirated into small bronchi, and cause multiple abscesses. a hook may be found useful in dealing with round, friable, foreign bodies; and in some cases the mechanical spoon or safety-pin closer may be used to advantage. the foreign body is then brought close to, but not crushed against the tube mouth. [174] _removal of animal objects from the tracheobronchial tree_ is readily accomplished with the side-curved forceps. leeches are not uncommon intruders in european countries. small insects are usually coughed out. worms and larvae may be found. cocaine or salt solution will cause a leech to loosen its hold. _foreign bodies in the upper-lobe bronchi_ are fortunately not common. if the object is not too far out to the periphery it may be grasped by the upper-lobe-bronchus forceps (fig. 90), guided by the collaboration of the fluoroscopist. these forceps are made so as to reach high into the ascending branches of the upper-lobe bronchus. full-curved coil-spring hooks will reach high, but must be used with the utmost caution, and the method of their disengagement must be practiced beforehand. _penetrating projectiles_.--foreign bodies that have penetrated the chest wall and lodged in the lung may be removed by oral bronchoscopy if the intruder is not larger than the lumen of the corresponding main bronchus (see bibliography, 43) [fig. 90.--schematic illustration of the author's upper-lobe-bronchus forceps in position grasping a pin in an anteriorly ascending branch of the upper-lobe bronchus. t, trachea; ul, upper-lobe bronchus; lb, left bronchus; sb, stem bronchus. these forceps are made to extend around 180 degrees.] rules for endoscopic foreign body extraction 1. never endoscope a foreign body case unprepared, with the idea of taking a preliminary look. 2. approach carefully the suspected location of a foreign body, so as not to override any portion of it. [175] 3. avoid grasping a foreign body hastily as soon as seen. 4. the shape, size and position of a foreign body, and its relations to surrounding structures, should be studied before attempting to apply the forceps. (exception cited in rule 10.) 5. preliminary study of a foreign body should be from a distance. 6. as the first grasp of the forceps is the best, it should be well planned beforehand so as to seize the proper part of the intruder. 7. with all long foreign bodies the motto should be "search, not for the foreign body, but for its nearer end." with pins, needles, and the like, with point upward, _search always for the point_. try to see it first. 8. remember that a long foreign body grasped near the middle becomes, mechanically speaking, a "toggle and ring." 9. remember that the mortality to follow failure to remove a foreign body does not justify probably fatal violence during its removal. 10. _laryngeally lodged_ foreign bodies, because of the likelihood of dislodgment and loss, may be seized by any part first presented, and plan of withdrawal can be determined afterward. 11. for similar reasons, laryngeal cases should be dealt with only in the author's position (fig. 53). 12. an esophagoscopy may be needed in a bronchoscopic case, or a bronchoscopy in an esophageal case. in every case both kinds of tubes should be sterile and ready before starting. it is the unexpected that happens in foreign body endoscopy. 13. do not pull on a foreign body unless it is properly grasped to come away readily without trauma. then do not pull hard. 14. do no harm, if you cannot remove the foreign body. 15. full-curved hooks are to be used in the bronchi with greatest caution, if used at all, lest they catch inextricably in branch bronchi. [176] 16. don't force a foreign body downward. coax it back. the deeper it gets the greater your difficulties. 17. the watchword of the bronchoscopist should be, "if i can do no good, i will at least do no harm." _fluoroscopic bronchoscopy_ is so deceptively easy from a superficial, theoretical, point of view that it has been used unsuccessfully in cases easily handled in the regular endoscopic way with the eye at the proximal tube-mouth. in a collected series of cases by various operators the object was removed in 66.7 per cent with a mortality of 41.6 per cent. in the problem of a pin located out of the field of bronchoscopic vision, the fluoroscopist will yield invaluable aid. an extremely delicate forceps is to be inserted closed into the invaded bronchus, the grasp on the object being confirmed by the fluoroscopist. it is to be kept in mind that while the object itself may be in the grasp of the forceps, the fluoroscope will not show whether there may not be included in the forceps' grasp a bronchial spur or other tissue, the tearing of which may be fatal. therefore traction must not be sufficient to lacerate tissue. if the foreign body does not come readily it must be released, and a new grasp may then be taken. all of the cautions in faulty seizure already mentioned, apply with particular force to fluoroscopic bronchoscopy. the fluoroscope is of aid in finding foreign bodies held in abscess cavities. the fluoroscope should show both the lateral and anteroposterior planes. to accomplish this quickly, two coolidge tubes and two screens are necessary. fluoroscopic bronchoscopy, because of its high mortality and low percentage of successes, should be tried only after regular, ocularly guided, peroral bronchoscopy has failed, and only by those who have had experience in ocularly guided bronchoscopy. [177] chapter xvi--foreign bodies in the bronchi for prolonged periods the sojourn of an inorganic foreign body in the bronchus for a year or more is followed by the development of bronchiectasis, pulmonary abscess, and fibrous changes. the symptoms of tuberculosis may all be presented, but tubercle bacilli have never been found associated with any of the many cases that have come to the bronchoscopic clinic.* the history of repeated attacks of malaise, fever, chills, and sweats lasting for a few days and terminated by the expulsion of an amount of foul pus, suggests the intermittent drainage of an abscess cavity, and special study should be made to eliminate foreign body as the cause of the condition, in all such cases, whether there is any history of a foreign body accident or not. bronchoscopy for diagnosis is to be done unless the etiology can be definitely proven by other means. in all cases of chronic chest disease foreign body should be eliminated as a matter of routine. * one exception has recently come to the clinic. 12 _the time of aspiration of a foreign body_ may be unknown, having possibly occurred in infancy, during narcosis, or the object may even enter the lower air passages without the patient being aware of the accident, as happened with a particularly intelligent business man who unknowingly aspirated the tip of an atomizer while spraying his throat. in many other cases the accident had been forgotten. in still others, in spite of the patient's statement of a conviction that the trouble was due to a foreign body he had aspirated, the physician did not consider it worthy of sufficient consideration to warrant a roentgenray examination. it is curious to note the various opinions held in regard to the gravity of the presence of a bronchial foreign body. one patient was told by his physician that the presence of a staple in his bronchus was an impossibility, for he would not have lived five minutes after the accident. others consider the presence of a foreign body in the bronchus as comparatively harmless, in spite of the repeated reports of invalidism and fatality in the medical literature of centuries. the older authorities state that all cases of prolonged bronchial foreign body sojourn died from phthisis pulmonalis, and it is still the opinion of some practitioners that the presence of a foreign body in the lung predisposes to the development of true tuberculosis. with the dissemination of knowledge regarding the possibility of bronchial foreign body, and the marvellous success in their removal by bronchoscopy, the cases of prolonged foreign body sojourn should decrease in number. it should be the recognized rule, and not the exception, that all chest conditions, acute or chronic, should have the benefit of roentgenographic study, even apart from the possibility of foreign body. often even with the clear history of foreign-body aspiration, both patient and physician are deluded by a relatively long period of quiescence in which no symptoms are apparent. this symptomless interval is followed sooner or later by ever increasing cough and expectoration of sputum, finally by bronchiectasis and pulmonary abscess, chronic sepsis, and invalidism. _pathology_.--if the foreign body completely obstructs a main bronchus, preventing both aeration and drainage, such rapid destruction of lung tissue follows that extensive pathologic changes may result in a few months, or even in a few weeks, in the case of irritating foreign bodies such as peanut kernels and soft rubber. very minute, inorganic foreign bodies may become encysted as in anthracosis. large objects, however, do not become encysted. the object is drawn down by gravity and aspirated into the smallest bronchus it can enter. later the negative pressure below from absorption of air impacts it still further. swelling of the bronchial mucosa from irritation plus infection completes the occlusion of the bronchus. retention of secretions and bacterial decomposition thereof produces first a "drowned lung" (natural passages full of pus); then sloughing or ulceration in the tissues plus the pressure of the pus, causes bronchiectasis; further destruction of the cartilaginous rings results in true abscess formation below the foreign body. the productive inflammation at the site of lodgement of the foreign body results in cicatricial contraction and the formation of a stricture at the top of the cavity, in which the foreign body is usually held. the abscess may extend to the periphery and rupture into the pleural cavity. it may drain intermittently into a bronchus. certain irritating foreign bodies, such as soft rubber, may produce gangrenous bronchitis and multiple abscesses. for observations on pathology (see bibliography, 38). _prognosis_.--if the foreign body be not removed, the resulting chronic sepsis or pulmonary hemorrhage will prove fatal. removal of the foreign body usually results in complete recovery without further local treatment. occasionally, secondary dilatation of a bronchial stricture may be required. all cases will need, besides removal of the foreign body, an antituberculous regimen, and offer a good prognosis if this be followed. _treatment_.--bronchoscopy should be done in all cases of chronic pulmonary abscess and bronchiectasis even though radiographic study reveals no shadow of foreign body. the patient by assuming a posture with the head lowered is urged to expel spontaneously all the pus possible, before the bronchoscopy. the aspirating bronchoscope (fig. 2, e) is often useful in cases where large amounts of secretion may be anticipated. granulations may require removal with forceps and sponging. disturbed granulations result in bleeding which further hampers the operation; therefore, they should not be touched until ready to apply the forceps, unless it is impossible to study the presentation without disturbing them. for this reason secretions hiding a foreign body should be removed with the aspirating tube (fig. 9) rather than by swabbing or sponge-pumping, when the bronchoscopic tube-mouth is close to the foreign body. it is inadvisable, however, to insert a forceps into a mass of granulations to grope blindly for a foreign body, with no knowledge of the presentation, the forceps spaces, or the location of branch-bronchial orifices into which one blade of the forceps may go. dilatation of a stricture may be necessary, and may be accomplished by the forms of bronchial dilators shown in fig. 25. the hollow type of dilator is to be used in cases in which the foreign body is held in the stricture (fig. 83). this dilator may be pushed down over the stem of such an object as a tack, and the stricture dilated without the risk of pushing the object downward. it is only rarely, however, that the point of a tack is free. dense cicatricial tissue may require incision or excision. _internal bronchotomy_ is doubtless, a very dangerous procedure, though no fatalities have occurred in any of the three cases in the bronchoscopic clinic. it is advisable only as a last resort. [181] chapter xvii--unsuccessful bronchoscopy for foreign bodies the limitations of bronchoscopic removal of foreign bodies are usually manifested in the failure to find a small foreign body which has entered a minute bronchus far down and out toward the periphery. when localization by means of transparent films, fluoroscopy, and endobronchial bismuth insufflation has failed, the question arises as to the advisability of endoscopic excision of the tissue intervening between the foreign body and bronchoscope with the aid of two fluoroscopes, one for the lateral and the other the vertical plane. with foreign bodies in the larger bronchi near the root of the lung such a procedure is unnecessary, and injury to a large vessel would be almost certain. at the extreme periphery of the lung the danger is less, for the vessels are smaller and serious hemorrhage less probable, through the retention and decomposition of blood in small bronchi with later abscess formation is a contingency. the nature of the bridge of tissue is to be considered; should it be cicatricial, the result of prolonged inflammatory processes, it may be carefully excised without very great risk of serious complications. the blood vessels are diminished in size and number by the chronic productive inflammation, which more than offsets their lessened contractility. the possibility of the foreign body being coughed out after suppurative processes have loosened its impaction is too remote; and the lesions established may result fatally even after the expulsion of the object. pulmonary abscess formation and rupture into the pleura should not be awaited, for the foreign body does not often follow the pus into the pleural cavity. it remains in the lung, held in a bed of granulation tissue. furthermore, to await the development is to subject the patient to a prolonged and perhaps fatal sepsis, or a fatal pulmonary hemorrhage from the erosion of a vessel by the suppurative process. the recent developments in thoracic surgery have greatly decreased the operative mortality of thoracotomy, so that this operation is to be considered when bronchoscopy has failed. bronchoscopy can be considered as having failed, for the time being, when two or more expert bronchoscopists on repeated search have been unable to find the foreign body or to disentangle it; but the art of bronchoscopy is developing so rapidly that the failures of a few years ago would be easy successes today. before considering thoracotomy months of study of the mechanical problem are advisable. it is probable that any foreign body of appreciable size that has gone down the natural passages can be brought back the same way. in the event of a foreign body reaching the pleura, either with or without pus, it should be removed immediately by pleuroscopy or by thoracotomy, without waiting for adhesive pleuritis. the problem may be summarized thus: 1. large foreign bodies in the trachea or large bronchi can always be removed by bronchoscopy. 2. the development of bronchoscopy having subsequently solved the problems presented by previous failures, it seems probable that by patient developmental endeavor, any foreign body of appreciable size that has gone down through the natural passages, can be bronchoscopically removed the same way, provided fatal trauma is avoided. at the author's bronchoscopic clinics 98.7 per cent of foreign bodies have been removed. chapter xviii--foreign bodies in the esophagus _etiology_.--the lodgement of foreign bodies in the esophagus is influenced by: 1. the shape of the foreign body (disc-shaped, pointed, irregular). 2. resiliency of the object (safety pins). 3. the size of the foreign body. 4. narrowing of the esophagus, spasmodic or organic, normal, or pathologic. 5. paralysis of the normal esophageal propulsory mechanism. the lodgement of a bolus of ordinary food in the esophagus is strongly suggestive of a preexisting narrowing of the lumen of either a spasmodic or organic nature; a large bolus of food, poorly masticated and hurriedly swallowed, may, however, become impacted in a perfectly normal esophagus. carelessness is the cause of over 80 per cent of the foreign bodies in the esophagus (see bibliography, 29). _site of lodgement_.--almost all foreign bodies are arrested in the cervical esophagus at the level of the superior aperture of the thorax. a physiologic narrowing is present at this level, produced in part by muscular contraction, and mainly by the crowding of the adjacent viscera into the fixed and narrow upper thoracic aperture. if dislodged from this position the foreign body usually passes downward to be arrested at the next narrowing or to pass into the stomach. the esophagoscopist who encounters the difficulty of introduction at the cricopharyngeal fold expects to find the foreign body above the fold. such, however, is almost never the case. the cricopharyngeus muscle functionates in starting the foreign body downward as if it were food; but the narrowing at the upper thoracic aperture arrests it because the esophageal peristaltic musculature is feeble as compared to the powerful inferior constrictor. _symptoms_.--_dysphagia_ is the most frequent complaint in cases of esophageally lodged foreign bodies. a very small object may excite sufficient spasm to cause aphagia, while a relatively large foreign body may be tolerated, after a time, so that the swallowing function may seem normal. intermittent dysphagia suggests the tilting or shifting of a foreign body in a valve-like fashion; but may be due to occlusion of the by-passages by food arrested by the foreign body. _dyspnea_ may be present if the foreign body is large enough to compress the trachea. _cough_ may be excited by reflex irritation, overflow of secretions into the larynx, or by perforation of the posterior tracheal wall, traumatic or ulcerative, allowing leakage of food or secretion into the trachea. (see chapter xii for discussion of symptomatology and diagnosis.) _prognosis_.--a foreign body lodged in the esophagus may prove quickly fatal from _hemorrhage_ due to perforation of a large vessel; from _asphyxia_ by pressure on the trachea; or from _perforation_ and _septic mediastinitis_. slower fatalities may result from suppuration extending to the trachea or bronchi with consequent edema and asphyxia. sooner or later, if not removed, the foreign body causes death. it may be tolerated for a long period of time, causing abscess, cervical cellulitis, fistulous tracts, and ultimately extreme stenosis from cicatricial contraction. perichondritis of the laryngeal or tracheal cartilages may follow, and result in laryngeal stenosis requiring tracheotomy. the damage produced by the foreign body is often much less than that caused by blind and ill-advised attempts at removal. if the foreign body becomes dislodged and moves downward, the danger of intestinal perforation is encountered. the _prognosis_, therefore, must be guarded so long as the intruder remains in the body. _treatment_.--it is a mistake to try to force a foreign body into the stomach with the stomach tube or bougie. sounding the esophagus with bougies to determine the level of the obstruction, or to palpate the nature of the foreign body, is unnecessary and dangerous. esophagoscopy should not be done without a previous roentgenographic and fluoroscopic examination of the chest and esophagus, except for urgent reasons. the level of the stenosis, and usually the nature of the foreign body, can thus be decided. blind instrumentation is dangerous, and in view of the safety and success of esophagoscopy, reprehensible. if for any reason removal should be delayed, bismuth sub-nitrate, gramme 0.6, should be given dry on the tongue every four hours. it will adhere to the denuded surfaces. the addition of calomel, gramme 0.003, for a few doses will increase the antiseptic action. should swallowing be painful, gramme 0.2 of orthoform or anesthesin will be helpful. emetics are inefficient and dangerous. holding the patient up by the heels is rarely, if ever, successful if the foreign body is in the esophagus. in the reported cases the intruder was probably in the pharynx. _external esophagotomy_ for the removal of foreign bodies is unjustifiable until esophagoscopy has failed in the hands of at least two skillful esophagoscopists. it has been the observation in the bronchoscopic clinic that every foreign body that has gone down through the mouth into the esophagus can be brought back the same way, unless it has already perforated the esophageal wall, in which event it is no longer a case of foreign body in the esophagus. the mortality of external esophagotomy for foreign bodies is from twenty to forty-two per cent, while that of esophagoscopy is less than two per cent, if the foreign body has not already set up a serious complication before the esophagoscopy. furthermore, external esophagotomy can be successful only with objects lodged in the cervical esophagus and, moreover, it has happened that after the esophagus has been opened, the foreign body could not be found because of dislodgement and passage downward during the relaxation of the general anesthesia. should this occur during esophagoscopy, the foreign body can be followed with the esophagoscope, and even if it is not overtaken and removed, no risk has been incurred. esophagoscopy is the one method of removal worthy of serious consideration. should it repeatedly fail in the hands of two skillful endoscopists, which will be very rarely, if ever, then external operation is to be considered in cervically lodged foreign bodies. [187] chapter xix--esophagoscopy for foreign body _indications_.--esophagoscopy is demanded in every case in which a foreign body is known to be, or suspected of being, in the esophagus. _contraindications_.--there is no absolute contraindication to careful esophagoscopy for the removal of foreign bodies, even in the presence of aneurism, serious cardiovascular disease, hypertension or the like, although these conditions would render the procedure inadvisable. should the patient be in bad condition from previous ill-advised or blind attempts at extraction, endoscopy should be delayed until the traumatic esophagitis has subsided and the general state improved. it is rarely the foreign body itself which is producing these symptoms, and the removal of the object will not cause their immediate subsidence; while the passage of the tube through the lacerated, infected, and inflamed esophagus might further harm the patient. moreover, the foreign body will be difficult to find and to remove from the edematous and bleeding folds, and the risk of following a false passage into the mediastinum or overriding the foreign body is great. water starvation should be relieved by means of proctoclysis and hypodermoclysis before endoscopy is done. the esophagitis is best treated by placing dry on the tongue at four-hour intervals the following powder: rx. anesthesin...gramme 0.12 bismuth subnitrate...gramme 0.6 calomel, gramme 0.006 to 0.003 may be added to each powder for a few doses to increase the antiseptic effect. if the patient can swallow liquids it is best to wait one week from the time of the last attempt at removal before any endoscopy for extraction be done. this will give time for nature to repair the damage and render the removal of the object more certain and less hazardous. perforation of the esophagus by the foreign body, or by blind instrumentation, is a contraindication to esophagoscopy. it is manifested by such signs as subcutaneous emphysema, swelling of the neck, fever, irritability, increase in pulsatory and respiratory rates, and pain in the neck or chest. gaseous emphysema is present in some cases, and denotes a dangerous infection. esophagoscopy should be postponed and the treatment mentioned at the end of this chapter instituted. after the subsidence of all symptoms other than esophageal, esophagoscopy may be done safely. pleural perforation is manifested by the usual signs of pneumothorax, and will be demonstrated in the roentgenogram. esophagoscopic extraction of foreign bodies it is unwise to do an endoscopy in a foreign-body case for the sole purpose of taking a preliminary look. everything likely to be needed for extraction of the intruder should be sterile and ready at hand. furthermore, all required instruments for laryngoscopy, bronchoscopy or tracheotomy should be prepared as a matter of routine, however rarely they may be needed. sponging should be done cautiously lest the foreign body be hidden in secretions or food accumulation, and dislodged. small food masses often lodge above the foreign body and are best removed with forceps. the folds of the esophagus are to be carefully searched with the aid of the lip of the esophagoscope. if the mucosa of the esophagus is lacerated with the forceps all further work is greatly hampered by the oozing; if the laceration involve the esophageal wall the accident may be fatal: and at best the tendency of the tube-mouth to enter the laceration and create a false passage is very great. _"overriding" or failure to find a foreign body known to be present_ is explained by the collapsed walls and folds covering the object, since the esophagoscope cannot be of sufficient size to smooth out these folds, and still be of small enough diameter to pass the constricted points of the esophagus noted in the chapter on anatomy. objects are often hidden just distal to the cricopharyngeal fold, which furthermore makes a veritable chute in throwing the end of the tube forward to override the foreign body and to interpose a layer of tissue between the tube and the object, so that the contact at the side of the tube is not felt as the tube passes over the foreign body (fig. 91). the chief factors in overriding an esophageal foreign body are: 1. the chute-like effect of the plica cricopharyngeus. 2. the chute-like effect of other folds. 3. the lurking of the foreign body in the unexplored pyriform sinus. 4. the use of an esophagoscope of small diameter. 5. the obscuration of the intruder by secretion or food debris. 6. the obscuration of the intruder by its penetration of the esophageal wall. 7. the obscuration of the intruder by inflammatory sequelae. [fig. 91.--illustrating the hiding of a coin by the folding downward of the plica cricopharyngeus. the muscular contraction throws the beak of the esophagoscope upward while the interposed tissue prevents the tactile appreciation of contact of the foreign body with the side of the tube after the tip has passed over the foreign body. other folds may in rare instances act similarly in hiding a foreign body from view. this overriding of a foreign body is apt to cause dangerous dyspnea by compression of the party wall.] _the esophageal speculum for the removal of foreign bodies_ is useful when the object is not more than 2 cm. below the cricoid in a child, and 3 cm. in the adult. the fold of the cricopharyngeus can be repressed posteriorward by the forceps which are then in position to grasp the object when it is found. the author's down-jaw forceps (fig. 22) are very useful to reach down back of the cricopharyngeal fold, because of the often small posterior forceps space. the speculum has the disadvantage of not allowing deeper search should the foreign body move downward. in infants, the child's size laryngoscope may be used as an esophageal speculum. general anesthesia is not only unnecessary but dangerous, because of the dyspnea created by the endoscopic tube. local anesthesia is unnecessary as well as dangerous in children; and its application is likely to dislodge the foreign body unless used as a troche. forbes esophageal speculum is excellent. mechanical problems of esophagoscopic removal of foreign bodies the bronchoscopic problems considered in the previous chapter should be studied. _the extraction of transfixed foreign bodies_ presents much the same problem as those in the bronchi, though there is no limit here to the distance an object may be pushed down to free the point. thin, sharp foreign bodies such as bones, dentures, pins, safety-pins, etcetera, are often found to lie crosswise in the esophagus, and it is imperative that one end be disengaged and the long axis of the object be made to correspond to that of the esophagus before traction for removal is made (fig. 92). should the intruder be grasped in the center and traction exerted, serious and perhaps fatal trauma might ensue. [191] [fig. 92.--the problem of the horizontally transfixed foreign body in the esophagus. the point, d, had caught as the bone, a, was being swallowed. the end, e, was forced down to c, by food or by blind attempts at pushing the bone downward. the wall, f, should be laterally displaced to j, with the esophagoscope, permitting the forceps to grasp the end, m, of the bone. traction in the direction of the dart will disimpact the bone and permit it to rotate. the rotation forceps are used as at k.] [fig. 93.--solution of the mechanical problem of the broad foreign body having a sharp point by version. if withdrawn with plain forceps as applied at a, the point b, will rip open the esophageal wall. if grasped at c, the point, d, will rotate in the direction of f and will trail harmlessly. to permit this version the rotation forceps are used as at h. on this principle flat foreign bodies with jagged or rough parts are so turned that the potentially traumatizing parts trail during withdrawal.] the extraction of broad, flat foreign bodies having a sharp point or a rough place on part of their periphery is best accomplished by the method of rotation as shown in fig. 93. _extraction of open safety-pins from the esophagus_.--an open safety pin with the point down offers no particular mechanical difficulty in removal. great care must be exercised, however, that it be not overridden or pushed upon, as either accident might result in perforation of the esophagus by the pin point. the coiled spring is to be sought, and when found, seized with the rotation forceps and the pin thus drawn into the esophagoscope to effect closure. an open safety-pin lodged point upward in the esophagus is one of the most difficult and dangerous problems. a roentgenogram should always be made in the plane showing the widest spread of the pin. it is to be remembered that the endoscopist can see but one portion of the pin at a time (except in cases of very small safety-pins) and that if he grasps the part first showing, which is almost invariably the keeper, fatal trauma will surely be inflicted when traction is made. it may be best to close the safety pin with the safety-pin closer, as illustrated in fig. 37. for this purpose arrowsmith's closer is excellent. in other cases it may prove best to disengage the point of the pin and to bring the pointed shaft into the esophagoscope with the tucker forceps and withdraw the pin, forceps, and esophagoscope, with the keeper and its shaft sliding alongside the tube. the rounded end of the keeper lying outside the tube allows it to slip along the esophageal walls during withdrawal without inflicting trauma; however, should resistance be felt, withdrawal must immediately cease and the pin must be rotated into a different plane to release the keeper from the fold in which it has probably caught. the sense of touch will aid the sense of sight in the execution of this maneuver (fig. 87). when the pin reaches the cricopharyngeal level the esophagoscope, forceps, and pin should be turned so that the keeper will be to the right, not so much because of the cricopharyngeal muscle as to escape the posteriorly protuberant cricoid cartilage. in certain cases in which it is found that the pointed shaft of a small safety pin has penetrated the esophageal wall, the pin has been successfully removed by working the keeper into the tube mouth, grasping the keeper with the rotation forceps or side-curved forceps, and pulling the whole pin into the tube by straightening it. this, however, is a dangerous method and applicable in but few cases. it is better to disengage the point by downward and inward rotation with the tucker forceps. _version of a safety pin_.--a safety pin of very small size may be turned over in a direction that will cause the point to trail. an advancing point will puncture. this is a dangerous procedure with a large safety pin. _endogastric version_.--a very useful and comparatively safe method is illustrated in figs. 94 and 95. in the execution of this maneuver the pin is seized by the spring with a rotation forceps, and thus passed along with the esophagoscope into the stomach where it is rotated so that the spring is uppermost. it can then be drawn into the tube mouth so as to protect the tissues during withdrawal of the pin, forceps, and esophagoscope as one piece. only very small safety-pins can be withdrawn through the esophagoscope. _spatula-protected method_.--safety-pins in children, point upward, when lodged high in the cervical esophagus may be readily removed with the aid of the laryngoscope, or esophageal speculum. the keeper end is grasped with the alligator forceps, while the spatular tip of the laryngoscope is worked under the point. instruments and foreign body are then removed together. often the pin point will catch in the light-chamber where it is very safely lodged. if the pin be then pulled upon it will straighten out and may be withdrawn through the tube. [fig. 94.--endogastric version. one of the author's methods of removal of upward pointed esophageally lodged open safety-pins by passing them into stomach, where they are turned and removed. the first illustration (a) shows the rotation forceps before seizing pin by the ring of the spring end. (forceps jaws are shown opening in the wrong diameter.) at b is shown the pin seized in the ring by the points of the forceps. at c is shown the pin carried into the stomach and about to be rotated by withdrawal. d, the withdrawal of the pin into the esophagoscope which will thereby close it. if withdrawn by flat-jawed forceps as at f, the esophageal wall would be fatally lacerated.] _double pointed tacks and staples_, when lodged point upward, must be turned so that the points trail on removal. this may be done by carrying them into the stomach and turning them, as described under safety-pins. _the extraction of foreign bodies of very large size_ from the esophagus is greatly facilitated by the use of general anesthesia, which relaxes the spasmodic contractions of the esophagus often occurring when attempt is made to withdraw the foreign body. general anesthesia, though entirely unnecessary for introduction of the esophagoscope, in any case may be used if the body is large, sharp, and rough, in order to prevent laceration through the muscular contractions otherwise incident to withdrawal.* in exceptional cases it may be necessary to comminute a large foreign body such as a tooth plate. a large smooth foreign body may be difficult to seize with forceps. in this case the mechanical spoon or the author's safety-pin closer may be used. * it must always be remembered that large foreign bodies are very prone to cause dyspnea that renders general anesthesia exceedingly dangerous especially in children. [fig. 95.--lateral roentgenogram of a safety-pin in a child aged 11 months, demonstrating the esophageal location of the pin in this case and the great value of the lateral roentgenogram in the localization of foreign bodies. the pin was removed by the author's method of endogastric version. (plate made by george c. johnston )] _the extraction of meat and other foods from the esophagus_ at the level of the upper thoracic aperture is usually readily accomplished with the esophageal speculum and forceps. in certain cases the mechanical spoon will be found useful. should the bolus of food be lodged at the lower level the esophagoscope will be required. _extraction of foreign bodies from the strictured esophagus_.--foreign bodies of relatively small size will lodge in a strictured esophagus. removal may be rendered difficult when the patient has an upper stricture relatively larger than the lower one, and the foreign body passing the first one lodges at the second. still more difficult is the case when the second stricture is considerably below the first, and not concentric. under these circumstances it is best to divulse the upper stricture mechanically, when a small tube can be inserted past the first stricture to the site of lodgement of the foreign body. _prolonged sojourn of foreign bodies in the esophagus_, while not so common as in the bronchi is by no means of rare occurrence. following their removal, stricture of greater or less extent is almost certain to follow from contraction of the fibrous-tissue produced by the foreign body. _fluoroscopic esophagoscopy_ is a questionable procedure, for the esophagus can be explored throughout by sight. in cases in which it is suspected that a foreign body, such as pin, has partially escaped from the esophagus, the fluoroscope may aid in a detailed search to determine its location, but under no circumstances should it be the guide for the application of forceps, because the transparent but vital tissues are almost certain to be included in the grasp. [197] complications and dangers of esophagoscopy for foreign bodies. asphyxia from the pressure of the foreign body, or the foreign body plus the esophagoscope, is a possibility (fig. 91). faulty position of the patient, especially a low position of the head, with faulty direction of the esophagoscope may cause the tube mouth to press the membranous tracheo-esophageal wall into the trachea, so as temporarily to occlude the tracheal lumen, creating a very dangerous situation in a patient under general anesthesia. prompt introduction of a bronchoscope, with oxygen and amyl nitrite insufflation and artificial respiration, may be necessary to save life. the danger is greater, of course, with chloroform than with ether anesthesia. cocain poisoning may occur in those having an idiosyncrasy to the drug. cocain should never be used with children, and is of little use in esophagoscopy in adults. its application is more annoying and requires more time than the esophagoscopic removal of the foreign bodies without local anesthesia. traumatic esophagitis, septic mediastinitis, cervical cellulitis, and, most dangerous, gangrenous esophagitis may be present, caused by the foreign body itself or ill-advised efforts at removal. perforation of the esophagus with the esophagoscope is rare, in skillful hands, if the esophageal wall is sound. the esophageal wall, however, may be weakened by ulceration, malignant disease, or trauma, so that the possibility of making a false passage should always deter the endoscopist from advancing the tube beyond a visible point of weakening. to avoid entering a false passage previously created, is often exceedingly difficult, and usually it is better to wait for obliterative adhesive inflammation to seal the tissue layers together. _treatment_.--acute esophagitis calls for rest in bed, sterile liquid food, and the administration of bismuth powder mentioned in the paragraph on contraindications. an ice bag applied to the neck may afford some relief. the mouth should be hourly cleansed with the following solution: dakin's solution 1 part cinnamon water 5 parts. emphysema unaccompanied by pyogenic processes usually requires no treatment, though an occasional case may require punctures of the skin to liberate the air. gaseous emphysema and pus formation urgently demand early external drainage, preferably behind the sternomastoid. should the pleura be perforated by sudden puncture pyo-pneumothorax is inevitable. prompt thoracotomy for drainage may save the patient's life if the mediastinum has not also been infected. foreign bodies ulcerating through may reach the lung without pleural leakage because of the sealing together of the visceral and parietal pleurae. in the serious degrees of esophageal trauma, particularly if the pleura be perforated, gastrostomy is indicated to afford rest of the esophagus, and for alimentation. a duodenal feeding tube may be placed through an esophagoscope passed into the stomach in the usual way through the mouth, avoiding by ocular guidance the perforation into which a blindly passed stomach tube would be very likely to enter, with probably dangerous results. [199] chapter xx--pleuroscopy _foreign bodies in the pleural cavity_ should be immediately removed. the esophageal speculum inserted through a small intercostal incision makes an excellent pleuroscope, its spatular tip being of particular value in moving the lung out of the way. this otherwise dark cavity is thus brilliantly illuminated without the necessity of making a large flap resection, an important factor in those cases in which there is no infection present. the pleura and wound may be immediately closed without drainage, if the pleura is not infected. excessive plus pressure or pus may require reopening. in one case in which the author removed a foreign body by pleuroscopy, healing was by first intention and the lung filled in a few days. drainage tubes that have slipped up into the empyemic cavity are foreign bodies. they are readily removed with the retrograde esophagoscope even through the smallest fistula. the aspirating canal keeps a clear field while searching for the drain. _pleuroscopy for disease_.--most pleural diseases require a large external opening for drainage, and even here the pleuroscope may be of some use in exploring the cavities. usually there are many adhesions and careful ray study may reveal one or more the breaking up of which will improve drainage to such an extent as to cure an empyema of long standing. repeated severing of adhesions, aspiration and sometimes incision of the thickened visceral pleura may be necessary. the author is so strongly imbued with the idea that local examination under full illumination has so revolutionized the surgery of every region of the body to which it has been applied, that every accessible region should be thus studied. the pleural cavity is quite accessible with or without rib-resection, and there is practically no risk in careful pleuroscopy. [201] chapter xxi--benign growths in the larynx benign growths in the larynx are easily and accurately removable by direct laryngoscopy; but perhaps no method has been more often misused and followed by most unfortunate results. it should always be remembered that benign growths are benign, and that hence they do not justify the radical work demanded in dealing with malignancy. the larynx should be worked upon with the same delicacy and respect for the normal tissues that are customary in dealing with the eye. _granulomata in the larynx_, while not true neoplasms, require extirpation in some instances. _vocal nodules_, when other methods of cure such as vocal rest, various vocal exercises, etcetera have failed may require surgical excision. this may be done with the laryngeal tissue forceps or with the author's vocal nodule forceps. sessile vocal nodules may be cured by touching them with a fine galvanocautery point, but all work on the vocal cords must be done with extreme caution and nicety. it is exceedingly easy to ruin a fine voice. _fibromata_, often of inflammatory genesis, are best removed with the laryngeal grasping forceps, though the small laryngeal punch or tissue forceps may be used. if very large, they may be amputated with the snare, the base being treated with galvanocautery though this is seldom advisable. strong traction should be avoided as likely to do irreparable injury to the laryngeal motility. _cystomata_ may get well after simple excision or galvanopuncture of a part of the wall of the sac, but complete extirpation of the sac is often required for cure. the same is true of _adenomata._ [202] angiomata, if extensive and deeply seated, may require deep excision, but usually cure results from superficial removal. usually no cauterization of the vessels at the base is necessary, either to arrest hemorrhage or to lessen the tendency to recurrence. a diffuse telangiectasis, should it require treatment, may be gently touched with a needle-pointed galvanocaustic electrode at a number of sittings. the galvanonocautery is a dangerous method to use in the larynx. radium offers the best results in this latter form of angioma, applied either internally or to the neck. _lymphoma, enchondroma and osteoma_, if not too extensively involving the laryngeal walls, may be excised with basket punch forceps, but lymphoma is probably better treated by radium.* _true myxomata and lipomata_ are very rare. _amyloid tumors_ are occasionally met with, and are very resistant to treatment. _aberrant thyroid tumors_ do not require very radical excision of normal base, but should be removed as completely as possible. in a general way, it may be stated that with benign growths in the larynx the best functional results are obtained by superficial rather than radical, deep extirpation, remembering that it is easier to remove tissue than to replace it, and that cicatrices impair or ruin the voice and may cause stenosis. * in a case reported by delavan a complete cure with perfect restoration of voice resulted from radium after i had failed to cure by operative methods. (proceedings american laryngological association, 1921.) [203] chapter xxii--benign growths in the larynx (continued) papillomata of the larynx in children of all benign growths in the larynx papilloma is the most frequent. it may occur at any age of childhood and may even be congenital. the outstanding fact which necessarily influences our treatment is the tendency to recurrences, followed eventually in practically all cases by a tendency to disappearance. in the author's opinion multiple papillomata constitute a benign, self-limited disease. there are two classes of cases. 1. those in which the growth gets well spontaneously, or with slight treatment, surgically or otherwise; and, 2, those not readily amenable to any form of treatment, recurrences appearing persistently at the old sites, and in entirely new locations. in the author's opinion these two classes of case represent not two different kinds of growths, but stages in the disease. those that get well after a single removal are near the end of the disease. papillomata are of inflammatory origin and are not true neoplasms in the strictest sense. _methods of treatment_.--irritating applications probably provoke recurrences, because the growths are of inflammatory origin. formerly laryngostomy was recommended as a last resort when all other means had failed. the excellent results from the method described in the foregoing paragraph has relegated laryngostomy to those cases that come in with a severe cicatricial stenosis from an injudicious laryngofissure; and even in these cases cure of the stenosis as well as the papillomata can usually be obtained by endoscopic methods alone, using superficial scalping off of the papillomata with subsequent laryngoscopic bouginage for the stenosis. thyrotomy for papillomata is mentioned only to be condemned. fulguration has been satisfactory in the hands of some, disappointing to others. it is easily and accurately applied through the direct laryngoscope, but damage to normal tissues must be avoided. radium, mesothorium, and the roentgenray are reported to have had in certain isolated cases a seemingly beneficial action. in my experience, however, i have never seen a cure of papillomata which could be attributed to the radiation. i have seen cases in which no effect on the growths or recurrence was apparent, and in some cases the growths seemed to have been stimulated to more rapid repullulations. in other most unfortunate cases i have seen perichondritis of the laryngeal cartilages with subsequent stenosis occurring after the roentgenotherapy. possibly the disastrous results were due to overdosage; but i feel it a duty to state the unfavorable experience, and to call attention to the difference between cancer and papillomata. multiple papillomata involve no danger to life other than that of easily obviated asphyxia, and it is moreover a benign self-limited disease that repullulates on the surface. in cancer we have an infiltrating process that has no limits short of life itself. _endolaryngeal extirpation_ of papillomata in children requires no anesthetic, general or local; the growths are devoid of sensibility. if, for any reason, a general anesthetic is used it should be only in tracheotomized cases, because the growths obstruct the airway. obstructed respiration introduces into general anesthesia an enormous element of danger. concerning the treatment of multiple papillomata it has been my experience in hundreds of cases that have come to the bronchoscopic clinic, that repeated superficial removals with blunt non-cutting forceps (see chapter i) will so modify the soil as to make it unfavorable for repullulation. the removals are superficial and do not include the subjacent normal tissue. radical removal of a papilloma situated, for instance, on the left ventricular band or cord, can in no way prevent the subsequent occurrence of a similar growth at a different site, as upon the epiglottis, or even in the fauces. furthermore, radical removal of the basal tissues is certain to impair the phonatory function. excellent results as to voice and freedom from recurrence have always followed repeated superficial removal. the time required has been months or a year or two. only rarely has a cure followed a single extirpation. if the child is but slightly dyspneic, the obstructing part of the growth is first removed without anesthesia, general or local; the remaining fungations are extirpated subsequently at a number of brief seances. the child is thus not terrified, soon loses dread of the removals, and appreciates the relief. should the child be very dyspneic when first seen, a low tracheotomy is immediately done, and after an interim of ten days, laryngoscopic removal of the growth is begun. tracheotomy probably has a beneficial effect on the disease. tracheal growths require the insertion of the bronchoscope for their removal. _papillomata in the larynx of adults_ are, on the whole, much more amenable to treatment than similar growths in children. tracheotomy is very rarely required, and the tendency to recurrence is less marked. many are cured by a single extirpation. the best results are obtained by removal of the growths with the laryngeal grasping-forceps, taking the utmost care to avoid including in the bite of the forceps any of the subjacent normal tissue. radical resection or cauterization of the base is unwise because of the probable impairment of the voice, or cicatricial stenosis, without in anyway insuring against repullulation. the papillomata are so soft that they give no sensation of traction to the forceps. they can readily be "scalped" off without any impairment of the sound tissues, by the use of the author's papilloma forceps (fig. 29). cutting forceps of all kinds are objectionable because they may wound the normal tissues before the sense of touch can give warning. a gentle hand might be trusted with the cup forceps (fig. 32, large size.) sir felix semon proved conclusively by his collective investigations that cancer cannot be caused by the repeated removals of benign growths. therefore, no fear of causing cancer need give rise to hesitation in repeatedly removing the repullulations of papillomata or other benign growths. indeed there is much clinical evidence elsewhere in the body, and more than a little such evidence as to the larynx, to warrant the removal of benign growths, repeated if necessary, as a prophylactic of cancer (bibliography, 19). [207] chapter xxiii--benign growths primary in the tracheobronchial tree extension of papillomata from the larynx into the cervical trachea, especially about the tracheotomy wound, is of relatively common occurrence. true primary growths of the tracheobronchial tree, though not frequent, are by no means rare. these primary growths include primary papillomata and fibromata as the most frequent, aberrant thyroid, lipomata, adenomata, granulomata and amyloid tumors. chondromata and osteochondromata may be benign but are prone to develop malignancy, and by sarcomatous or other changes, even metaplasia. edematous polypi and other more or less tumor-like inflammatory sequelae are occasionally encountered. _symptoms of benign tumors of the tracheobronchial tree_.--cough, wheezing respiration, and dyspnea, varying in degree with the size of the tumor, indicate obstruction of the airway. associated with defective aeration will be the signs of deficient drainage of secretions. roentgenray examination may show the shadow of enchondromata or osteomata, and will also show variations in aeration should the tumor be in a bronchus. _bronchoscopic removal of benign growths_ is readily accomplished with the endoscopic punch forceps shown in figs. 28 and 33. quick action may be necessary should a large tumor producing great dyspnea be encountered, for the dyspnea is apt to be increased by the congestion, cough, and increased respiration and spasm incidental to the presence of the bronchoscope in the trachea. general anesthesia, as in all cases showing dyspnea, is contraindicated. the risks of hemorrhage following removal are very slight, provided fungations on an aneurismal erosion be not mistaken for a tumor. multiple papillomata when very numerous are best removed by the author's "coring" method. this consists in the insertion of an aspirating bronchoscope with the mechanical aspirator working at full negative pressure. the papillomata are removed like coring an apple; though the rounded edge of the bronchoscope does not even scratch the tracheal mucosa. many of the papillomata are taken off by the holes in the bronchoscope. aspiration of the detached papillomata into the lungs is prevented by the corking of the tube-mouth with the mass of papillomata held by the negative pressure at the canal inlet orifice. chapter xxiv--benign neoplasms of the esophagus as a result of prolonged inflammation edematous polypi and granulomata are not infrequently seen, but true benign tumors of the esophagus are rare affections. keloidal changes in scar tissue may occur. cases of retention, epithelial and dermoid cysts have been observed; and there are isolated reports of the finding of papillomata, fibromata, lipomata, myomata and adenomata. the removal of these is readily accomplished with the tissue forceps (fig. 28), if the growths are small and projecting into the esophageal lumen. the determination of the advisability of the removal of keloidal scars would require careful consideration of the particular case, and the same may be said of very large growths of any kind. the extreme thinness of the esophageal walls must be always in the mind of the esophagoscopist if he would avoid disaster. [210] chapter xxv--endoscopy in malignant disease of the larynx the general surgical rule applying to individuals past middle life, that benign growths exposed to irritation should be removed, probably applies to the larynx as well as to any other epithelialized structure. the facility, accuracy and thoroughness afforded by skilled, direct, laryngeal operation offers a means of lessening the incidence of cancer. to a much greater extent the facility, accuracy, and thoroughness contribute to the cure of cancer by establishing the necessary early diagnosis. well-planned, careful, external operation (laryngofissure) followed by painstaking after-care is the only absolute cure so far known for malignant neoplasms of the larynx; and it is a cure only in those intrinsic cases in which the growth is small, and is located in the anterior two-thirds of the intrinsic area. by limiting operations strictly to this class of case, eighty-five per cent of cures may be obtained.* in determining the nature of the growth and its operability the limits of the usefulness of direct endoscopy are reached. it is very unwise to attempt the extirpation of intrinsic laryngeal malignancy by the endoscopic method, for the reason that the full extent of the growth cannot be appreciated when viewed only from above, and the necessary radical removal cannot be accurately or completely accomplished. * the author's results in laryngofissure have recently fallen to 79 per cent of relative cures by thyrochondrotomy. _malignant disease of the epiglottis_, in those rare cases where the lesion is strictly limited to the tip is, however, an exception. if amputation of the epiglottis will give a sufficiently wide removal, this may be done en masse with a heavy snare, and has resulted in complete cure. very small growths may be removed sufficiently widely with the punch forceps (fig. 33); but piece meal removal of malignancy is to be avoided. _differential diagnosis of laryngeal growths in the larynx of adults_.--determination of the nature of the lesion in these cases usually consists in the diagnosis by exclusion of the possibilities, namely, 1. lues. 2. tuberculosis, including lupus. 3. scleroma. 4. malignant neoplasm. in the bronchoscopic clinic the following is the routine procedure: 1. a wassermann test is made. if negative, and there remains a suspicion of lues, a therapeutic test with mercury protoiodid is carried out by keeping the patient just under the salivation point for eight weeks; during which time no potassium iodid is given, lest its reaction upon the larynx cause an edema necessitating tracheotomy. if no improvement is noticed lues is excluded. if the wassermann is positive, malignancy and the other possibilities are not considered as excluded until the patient has been completely cured by mercury, because, for instance, a leutic or tuberculous patient may have cancer; a tuberculous patient may have lues; or a leutic patient, tuberculosis. 2. pulmonary tuberculosis is excluded by the usual means. if present the laryngeal lesion may or may not be tuberculous; if the laryngoscopic appearances are doubtful a specimen is taken. lupoid laryngeal tuberculosis so much resembles lues that both the therapeutic test and biopsy may be required for certainty. 3. in all cases in which the diagnosis is not clear a specimen is taken. this is readily accomplished by direct laryngoscopy under local anesthesia, using the regular laryngoscope or the anterior commissure laryngoscope. the best forceps in case of large growths are the alligator punch forceps (fig. 33). smaller growths require tissue forceps (fig. 28). in case of small growths, it is best to remove the entire growth; but without any attempt at radical extirpation of the base; because, if the growth prove benign it is unnecessary; if malignant, it is insufficient. _inspection of the party wall in cases of suspected laryngeal malignancy_.--when taking a specimen the party wall should be inspected by passing a laryngoscope or, if necessary, an esophageal speculum down through the laryngopharynx and beyond the cricopharyngeus. if this region shows infiltration, all hope of cure by operation, however radical, should be abandoned. _radium and the therapeutic roentgenray_ have given good results, but not such as would warrant their exclusive use in any case of malignancy in the larynx operable by laryngofissure. with inoperable cases, excellent palliative results are obtained. in some cases an almost complete disappearance of the growth has occurred, but ultimately there has been recurrence. the method of application of the radium, dosage, and its screening, are best determined by the radiologist in consultation with the laryngologist. radium may be applied externally to the neck, or suspended in the larynx; radium-containing needles may be buried in the growth, or the emanations, imprisoned in glass pearls or capillary tubes, may be inserted deeply into the growth by means of a small trocar and cannula. for all of these procedures direct laryngoscopy affords a ready means of accurate application. tracheotomy is necessary however, because of the reactionary swelling, which may be so great as to close completely the narrowed glottic chink. where this is the case, the endolaryngeal application of the radium may be made by inserting the container through the tracheotomic wound, and anchoring it to the cannula. the author is much impressed with freer's method of radiation from the pyriform sinus in such cases as those in which external radiation alone is deemed insufficient. the work of drs. d. bryson delavan and douglass m. quick forms one of the most important contributions to the subject of the treatment of radium by cancer. (see proceedings of the american laryngological association, 1922; also proceedings of the tenth international otological congress, paris, 1922.) [214] chapter xxvi--bronchoscopy in malignant growths of the trachea the trachea is often secondarily invaded by malignancy of the esophagus, thyroid gland, peritracheal or peribronchial glands. primary malignant neoplasms of the trachea or bronchus have not infrequently been diagnosticated by bronchoscopy. peritracheal or peribronchial malignancy may produce a compressive stenosis covered with normal mucosa. endoscopically, the wall is seen to bulge in from one side causing a crescentic picture, or compression of opposite walls may cause a "scabbard" or pear shaped lumen. endotracheal and endobronchial malignancy ulcerate early, and are characterized by the bronchoscopic view of a bleeding mass of fungating tissue bathed in pus and secretion, usually foul. the diagnosis in these cases rests upon the exclusion of lues, and is rendered certain by the removal of a specimen for biopsy. sarcoma and carcinoma of the thyroid when perforating the trachea may become pedunculated. in such cases aberrant non-pathologic thyroid must be excluded by biopsy. endothelioma of the trachea or bronchus may also assume a pedunculated form, but is more often sessile. _treatment_.--pedunculated malignant growths are readily removed with snare or punch forceps. cure has resulted in one case of the author following bronchoscopic removal of an endothelioma from the bronchus; and a limited carcinoma of the bronchus has been reported cured by bronchoscopic removal, with cauterization of the base. most of the cases, however, will be subjects for palliative tracheotomy and radium therapy. it will be found necessary in many of the cases to employ the author's long, cane-shaped tracheal cannula (fig. 104, a), in order to pipe the air down to one or both bronchi past the projecting neoplasm. it has recently been demonstrated that following the intravenous injection of a suspension of the insoluble salt, radium sulphate, that the suspended particles are held in the capillaries of the lung for a period of one year. intravenous injections of a watery suspension, and endobronchial injections of a suspension of radium sulphate in oil, have had definite beneficial action. while as yet, no relatively permanent cures of pulmonary malignancy have been obtained, the amelioration and steady improvement noted in the technic of radium therapy are so encouraging that every inoperable case should be thus treated, if the disease is not in a hopelessly advanced stage. in a case under the care of dr. robert m. lukens at the bronchoscopic clinic, a primary epithelioma of the trachea was retarded for 2 years by the use of radium applied by dr. william s. newcomet, radium-therapist, and miss katherine e. schaeffer, technician. [216] chapter xxvii--malignant disease of the esophagus cancer of the esophagus is a more prevalent disease than is commonly thought. in the male it usually develops during the fourth and fifth decades of life. there is in some cases the history of years of more or less habitual consumption of strong alcoholic liquors. in the female the condition often occurs at an earlier age than in the male, and tends to run a more protracted course, preceeded in some cases by years of precancerous dysphagia. squamous-celled epithelioma is the most frequent type of neoplasm. in the lower third of the esophagus, cylindric cell carcinoma may be found associated with a like lesion in the stomach. sarcoma of the esophagus is relatively rare (bibliography 1, p. 449). the sites of the lesion are those of physiologic narrowing of the esophagus. the middle third is most frequently involved; and the lower third, near the cardia, comes next in frequency. cancer of the lower third of the esophagus preponderates in men, while cancer of the upper orifice is, curiously, more prevalent in women. the lesion is usually single, but multiple lesions, resulting from implantation metastases have been observed (bibliography 1, p. 391). bronchoesophageal fistula from extension is not uncommon. _symptoms_.--malignant disease of the esophagus is rarely seen early, because of the absence, or mildness, of the symptoms. dysphagia, the one common symptom of all esophageal disease, is often ignored by the patient until it becomes so marked as to prevent the taking of solid food; therefore, the onset may have the similitude of abruptness. any well masticated solid food can be swallowed through a lumen 5 millimeters in diameter. the inability to maintain the nutrition is evidenced by loss of weight and the rapid development of cachexia. when the stenosis becomes so severe that the fluid intake is limited, rapid decline occurs from water starvation. pain is usually a late symptom of the disease. it may be of an aching character and referred to the vertebral region or to the neck; or it may only accompany the act of swallowing. blood-streaked, regurgitated material, and the presence of odor, are late manifestations of ulceration and secondary infection. in some cases, constant oozing of blood from the ulcerated area adds greatly to the cachexia. if the recurrent laryngeal nerves are involved, unilateral or bilateral paralysis of the larynx may complicate the symptoms by cough, dyspnea, aphonia, and possibly septic pneumonia. _diagnosis_.--it has been estimated that 70 per cent of stenoses of the esophagus in adults are malignant in nature. this should stimulate the early and careful investigation of every case of dysphagia. when all cases of persistent dysphagia, however slight, are endoscopically studied, precancerous lesions may be discovered and treated, and the limited malignancy of the early stages may be afforded surgical treatment while yet there is hope of complete removal. luetic and tuberculous ulceration of the esophagus are to be eliminated by suitable tests, supplemented in rare instances by biopsy. aneurysm of the aorta must in all cases of dysphagia be excluded, for the dilated aorta may be the sole cause of the condition, and its presence contraindicates esophagoscopy because of the liability of rupture. foreign body is to be excluded by history and roentgenographic study. spasmodic stenosis of the esophagus may or may not have a malignant origin. esophagoscopy and removal of a specimen for biopsy renders the diagnosis certain. it is to be especially remembered, however, that it is very unwise to bite through normal mucosa for the purpose of taking a specimen from a periesophageal growth. fungations and polypoid protuberances afford safe opportunities for the removal of specimens of tissue. _the esophagoscopic appearances of malignant disease_, varying with the stage and site of origin of the growth, may present as follows:- 1. submucosal infiltration covered by perfectly normal membrane, usually associated with more or less bulging of the esophageal wall, and very often with hardness and infiltration. 2. leucoplakia. 3. ulceration projecting but little above the surface at the edges. 4. rounded nodular masses grouped in mulberry-like form, either dark or light red in color. 5. polypoid masses. 6. cauliflower fungations. in considering the esophagoscopic appearances of cancer, it is necessary to remember that after ulceration has set in, the cancerous process may have engrafted upon it, and upon its neighborhood, the results of inflammation due to the mixed infections. cancer invading the wall from without may for a long time be covered with perfectly normal mucous membrane. the significant signs at this early stage are: 1. absence of one or more of the normal radial creases between the folds. 2. asymmetry of the inspiratory enlargement of lumen. 3. sensation of hardness of the wall on palpation with the tube. 4. the involved wall will not readily be made to wrinkle when pushed upon with the tube mouth. in all the later forms of lesions the two characteristics are (a) the readiness with which oozing of blood occurs; and (b) the sense of rigidity, or fixation, of the involved area as palpated with the esophagoscope, in contrast to the normally supple esophageal wall. esophageal dilatation above a malignant lesion is rarely great, because the stenosis is seldom severely obstructive until late in the course of the disease. _treatment_.--the present 100 per cent mortality in cancer of the esophagus will be lowered and a certain percentage of surgical cures will be obtained when patients with esophageal symptoms are given the benefit of early esophagoscopic study. the relief or circumvention of the dysphagia requires early measures to prevent food and water starvation. _bouginage_ of a malignant esophagus to increase temporarily the size of the stenosed lumen is of questionable advisability, and is attended with the great risk of perforating the weakened esophageal wall. _esophageal intubation_ may serve for a time to delay gastrostomy but it cannot supplant it, nor obviate the necessity for its ultimate performance. the charters-symonds or guisez esophageal intubation tube is readily inserted after drawing the larynx forward with the laryngoscope. the tube must be changed every week or two for cleaning, and duplicate tubes must be ready for immediate reinsertion. eventually, a smaller, and then a still smaller tube are needed, until finally none can be introduced; though in some cases the tube can be kept in the soft mass of fungations until the patient has died of hemorrhage, exhaustion, complications or intercurrent disease. _gastrostomy_ is always indicated as the disease progresses, and it should be done before nutrition is greatly impaired. surgeons often hesitate thus to "operate on an inoperable case;" but it must be remembered that no one should be allowed to die of hunger and thirst. the operation should be done before inanition has made serious inroads. as in the case of tracheotomy, we always preach doing it early, and always do it late. if postponed too long, water starvation may proceed so far that the patient will not recover, because the water-starved tissues will not take up water put in the stomach. _radiotherapy_.--radium and the therapeutic roentgenray are today our only effective means of retarding the progress of esophageal malignant neoplasms. no permanent cures have been reported, but marked temporary improvement in the swallowing function and prolongation of life have been repeatedly observed. the combination of radium treatment applied within the esophageal lumen and the therapeutic roentgenray through the chest wall, has retarded the progress of some cases. the dosage of radium or the therapeutic ray must be determined by the radiologist for the particular individual case; its method of application should be decided by consultation of the radiologist and the endoscopist. two fundamental points are to be considered, however. the radium capsule, if applied within the esophagus, should be so screened that the soft, irritating, beta rays, and the secondary rays, are both filtered out to prevent sloughing of the esophageal mucosa. the dose should be large enough to have a lethal effect upon the cancer cells at the periphery of the growth as well as in the center. if the dose be insufficient, development of the cells at the outside of the growth is stimulated rather than inhibited. it is essential that the radium capsule be accurately placed in the center of the malignant strictured area and this can be done only by visual control through the esophagoscope (fig. 95) drs. henry k. pancoast, george e. pfahler and william s. newcomet have obtained very satisfactory palliative effects from the use of radium in esophageal cancer. [221] chapter xxviii--direct laryngoscopy in diseases of the larynx the diagnosis of laryngeal disease in young children, impossible with the mirror, has been made easy and precise by the development of direct laryngoscopy. no anesthetic, local or general, should be used, for the practised endoscopist can complete the examination within a minute of time and without pain to the patient. the technic for doing this should be acquired by every laryngologist. anesthesia is absolutely contraindicated because of the possibility of the presence of diphtheria, and especially because of the dyspnea so frequently present in laryngeal disease. to attempt general anesthesia in a dyspneic case is to invite disaster (see tracheotomy). it is to be remembered that coughing and straining produce an engorgement of the laryngeal mucosa, so that the first glance should include an estimation of the color of the mucosa, which, as a result of the engorgement, deepens with the prolongation of the direct laryngoscopy. _chronic subglottic edema_, often the result of perichondritis, may require linear cauterization at various times, to reduce its bulk, after the underlying cause has been removed. _perichondritis and abscess_, and their sequelae are to be treated on the accepted surgical precepts. they may be due to trauma, lues, tuberculosis, enteric fever, pneumonia, influenza, etc. _tuberculosis of the larynx_ calls for conservatism in the application of surgery. ulceration limited to the epiglottis may justify amputation of the projecting portion or excision of only the ulcerated area. in either case, rapid healing may be expected, and relief from the odynphagia is sometimes prompt. amputation of the epiglottis is, however, not to be done if ulceration in other portions of the larynx coexist. the removal of tuberculomata is sometimes indicated, and the excision of limited ulcerative lesions situated elsewhere than on the epiglottis may be curative. these measures as well as the galvanocautery are easily executed by the facile operator; but their advisability should always be considered from a conservative viewpoint. they are rarely justifiable until after months of absolute silence and a general antituberculous regime have failed of benefit. _galvanopuncture_ for laryngeal tuberculosis has yielded excellent results in reducing the large pyriform edematous swellings of the aryepiglottic folds when ulceration has not yet developed. deep punctures at nearly a white heat, made perpendicular to the surface, are best. care must be exercised not to injure the cricoarytenoid joint. fungating ulcerations may in some cases be made to cicatrize by superficial cauterization. excessive reactions sometimes follow, so that a light application should be made at the first treatment. _congenital laryngeal stridor_ is produced by an exaggeration of the infantile type of larynx. the epiglottis will be found long and tapering, its lateral margins rolled backward so as to meet and form a cylinder above. the upper edges of the aryepiglottic folds are approximated, leaving a narrow chink. the lack of firmness in these folds and the loose tissue in the posterior portion of the larynx, favors the drawing inward of the laryngeal aperture by the inspiratory blast. the vibration of the margins of this aperture produces the inspiratory stridor. diagnosis is quickly made by the inspection of the larynx with the infant diagnostic laryngoscope. no anesthetic, general or local, is needed. stridorous respiration may also be due to the presence of laryngeal papillomata, laryngeal spasm, thymic compression, congenital web, or an abnormal inspiratory bulging into the trachea of the posterior membranous tracheo-esophageal wall. the term "congenital laryngeal stridor" should be limited to the first described condition of exaggerated infantile larynx. _treatment of congenital laryngeal stridor_ should be directed to the relief of dyspnea, and to increasing the nutrition and development of the infant. the insertion of a bronchoscope will temporarily relieve an urgent dyspneic attack precipitated by examination; but this rarely happens if the examination is not unduly prolonged. tracheotomy may be needed to prevent asphyxia or exhaustion from loss of sleep; but very few cases require anything but attention to nutrition and hygiene. recovery can be expected with development of the laryngeal structures. _congenital webs of the larynx_ require incision or excision, or perhaps simply bouginage. congenital goiter and congenital laryngeal paralysis, both of which may cause stertorous breathing, are considered in connection with other forms of stenosis of the air passages. _aphonia_ due to cicatricial webs of the larynx may be cured by plastic operations that reform the cords, with a clean, sharp anterior commissure, which is a necessity for clear phonation. the laryngeal scissors and the long slender punch are often more useful for these operations than the knife. [224] chapter xxix--bronchoscopy in diseases of the trachea and bronchi _the indications for bronchoscopy in disease_ are becoming increasingly numerous. among the more important may be mentioned: 1. bronchiectasis. 2. chronic pulmonary abscess. 3. unexplained dyspnea. 4. dyspnea unrelieved by tracheotomy calls for bronchoscopic search for deeper obstruction. 5. paralysis of the recurrent laryngeal nerve, the cause of which is not positively known. 6. obscure thoracic disease. 7. unexplained hemoptysis. 8. unexplained cough. 9. unexplained expectoration. _contraindications to bronchoscopy in disease_ do not exist if the bronchoscopy is really needed. serious organic disease such as aneurysm, hypertension, advanced cardiac disease, might render bronchoscopy inadvisable except for the removal of foreign bodies. _bronchoscopic appearances in disease_.--the first look should note the color of the bronchial mucosa, due allowance being made for the pressure of tubal contact, secretions, and the engorgement incident to continued cough. the carina trachealis normally moves slowly forward as well as downward during deep inspiration, returning quickly during expiration. impaired movement of the carina indicates peritracheal and peribronchial pathology, the fixation being greatest in advanced cancer. in children and in the smaller tubes of the adult, the lengthening and dilatation of the bronchi during inspiration, and their shortening and contraction during expiration are readily seen. _anomalies of the tracheobronchial tree_.--tracheobronchial anomalies are relatively rare. congenital esophagotracheal and esophagobronchial fistulae are occasionally seen, and cases of cervicotracheal fistulae have been reported. congenital webs and diverticula of the trachea are cited infrequently. laryngoptosis and deviation of the trachea may be congenital. substernal goitre, aneurysm, malignant growths, and various mediastinal adenopathies may displace the trachea from its normal course. the emphysematous chest fixed in the deep voluntary inspiratory position produces in some cases an elevation of the superior thoracic aperture simulating laryngoptosis (bibliography r, pp. 468, 594). _compression stenosis of the trachea and bronchi_.--compression of the trachea is most commonly caused by goiter, substernal or cervical, aneurysm, malignancy, or, in children, by enlarged thymus. less frequently, enlarged mediastinal tuberculous, leukemic, leutic or hodgkin's glands compress the airway. the left bronchus may be stenosed by pressure from a hypertrophied cardiac auricle. compression stenosis of the trachea associated with pulmonary emphysema accounts for the dyspnea during attacks of coughing. the endoscopic picture of compression stenosis is that of an elliptical or scabbard-shaped lumen when the bronchus is at rest or during inspiration. concentric funnel-like compression stenosis, while rare, may be produced by annular growths. _treatment of compression stenoses of the trachea_.--if the thymus be at fault, rapid amelioration of symptoms follows roentgenray or radium therapy. tracheotomy and the insertion of the long cane-shaped cannula (fig. 104) past the compressed area is required in the cases caused by conditions less amenable to treatment than thymic enlargement. permanent cure depends upon the removability of the compressive mass. should the bronchi be so compressed by a benign condition as to prevent escape of secretions from the subjacent air passages, bronchial intubation tubes may be inserted, and, if necessary, worn constantly. they should be removed weekly for cleansing and oftener if obstructed. _influenzal laryngotracheobronchitis_.--influenzal infection, not always by the same organism, sweeps over the population, attacking the air passages in a violent and quite characteristic way. bronchoscopy shows the influenzal infection to be characterized by intense reddening and swelling of the mucosa. in some cases the swelling is so great as to necessitate tracheotomy, or intubation of the larynx; and if the edema involve the bronchi, occlusion may be fatal. hemorrhagic spots and superficial erosions are commonly seen, and a thick, tenacious exudate, difficult of expectoration, lies in patches in the trachea. infants may asphyxiate from accumulation of this secretion which they are unable to expel. the differential diagnosis from diphtheria is sometimes difficult. the absence of true membrane and the failure to find diphtheria bacilli in smears taken from the trachea are of aid but are not infallible. in doubtful cases, the administration of diphtheria antitoxin is a wise precaution pending the establishment of a definite diagnosis. the pseudomembrane sometimes present in influenzal tracheobronchitis is thinner and less pulpy than that of the earlier stages of diphtheria. the casts of the later stages do not occur in influenzal tracheobronchitis (bibliography i, p. 480). _edematous tracheobronchitis_.--this is chiefly observed in children. the most frequently encountered form is the epidemic disease to which the name "influenza" has been given (q.v. supra). the only noticeable difference between the epidemic and the sporadic cases is in the more general susceptibility to the infective agent, which gives the influenzal form an appearance of being more virulently infective. possibly the sporadic form is simply the attack of children not immunized by a previous attack during an epidemic. there is another form of edematous tracheobronchitis often of great severity and grave prognosis, that results from the aspiration of irritating liquids or vapors, or of certain organic substances such as peanut kernels, watermelon seeds, etcetera. tracheotomy should be done if marked dyspnea be present. secretions can then be easily removed and medication in the form of oily solutions be instilled at will into the trachea. in the bronchoscopic clinic many children have been kept alive for days, and their lives finally saved by aspiration of thick, tough, sometimes clotted and crusted secretions, with the aspirating tube (fig. 10). it is better in these cases not to pass the bronchoscope repeatedly. if, however, evidences of obstruction remain, after aspiration, it is necessary to see the nature of the obstruction and relieve it by removal, dilatation, or bronchial intubation as the case may require. it is all a matter of "plumbing" i.e., clearing out the "pipes," and maintaining a patulous airway. _tracheobronchial diphtheria_.--urgent dyspnea in diphtheria when no membrane and but slight lessening of the laryngeal airway is seen, calls for bronchoscopy. many lives have been saved by the bronchoscopic removal of membrane obstructing the trachea or bronchi. in the early stages, pulpy masses looking like "mother" of vinegar are very obstructive. later casts of membrane may simulate foreign bodies. the local application of diphtheria antitoxin to the trachea and bronchi has also been recommended. a preparation free from a chemical irritant should be selected. _abscess of the lung_.--if of foreign-body origin, pulmonary abscess almost invariably heals after the removal of the object and a regime of fresh air and rest, without local measures of any kind. acute pulmonary abscess from other causes may require bronchoscopic drainage and gentle dilatation of the swollen and narrowed bronchi leading to it. some of these bronchi are practically fistulae. obstructive granulations should be removed with crushing, not biting forceps. the regular foreign-body forceps are best for this purpose. caution should be used as to removal of the granulations with which the abscess "cavity" is filled in chronic cases. the term "abscess" is usually loosely applied to the condition of drowned lung in which the pus has accumulated in natural passages, and in which there is neither a new wall nor a breaking down of normal walls. chronic lung-abscess is often successfully treated by weekly bronchoscopic lavage with 20 cc. or more of a warm, normal salt solution, a 1:1000 watery potassium permanganate solution, or a weak iodine solution as in the following formula: rx. monochlorphenol (merck) .12 lugol's solution 8.00 normal salt solution 500. perhaps the best procedure is to precede medicinal applications by the clearing out of the purulent secretions by aspiration with the aspirating bronchoscope and the independent aspirating tube, the latter being inserted into passages too small to enter with the bronchoscope, and the endobronchial instillation of from 10 to 30 cc. of the medicament. the following have been used: argyrol, 1 per cent watery solution; silvol, 1 per cent watery solution; iodoform, oil emulsion 10 per cent; guaiacol, 10 per cent solution in paraffine oil; gomenol, 20 per cent solution in oil; or a bismuth subnitrate suspension in oil. robert m. lukens and william f. moore of the bronchoscopic clinic report excellent results in post-tonsillectomy abscesses from one tenth of one per cent phenol in normal salt solution with the addition of 2 per cent lugol's solution. chlorinated solutions are irritating, and if used, require copious dilution. liquid petrolatum with a little oil of eucalyptus has been most often the medium. _gangrene of the lung_.--pulmonary gangrene has been followed by recovery after the endobronchial injection of oily solutions of gomenol and guaiacol (guisez). the injections are readily made through the laryngoscope without the insertion of a bronchoscope. a silk woven catheter may be used with an ordinary glass syringe or a long-nozzled laryngeal syringe, or a bronchoscopic syringe may be used. _lung-mapping_ by a roentgenogram taken promptly after the bronchoscopic insufflation of bismuth subnitrate powder or the injection of a suspension of bismuth in liquid petrolatum is advisable in most cases of pulmonary abscess before beginning any kind of treatment. _bronchial stenosis_.--stenosis of one or more bronchi results at times from cicatricial contraction following secondary infection of leutic, tuberculous or traumatic lesions. the narrowing resulting from foreign body traumatism rarely requires secondary dilatation after the foreign body has been removed. tuberculous bronchial stenoses rarely require local treatment, but are easily dilated when necessary. luetic cicatricial stenosis may require repeated dilatation, or even bronchial intubation. endobronchial neoplasms may cause a subjacent bronchiectasis, and superjacent stenosis; the latter may require dilatation. cicatricial stenoses of the bronchi are readily recognizable by the scarred wall and the absence of rings at or near the narrowing. _bronchiectasis_.--in most cases of bronchiectasis there are strong indications for a bronchoscopic diagnosis, to eliminate such conditions as foreign body, cicatricial bronchial stenosis, or endobronchial neoplasm as etiologic factors. in the idiopathic types considerable benefit has resulted from the endobronchial lavage and endobronchial oily injections mentioned under lung abscess. it is probable that if bronchoscopic study were carried out in every case, definite causes for many so-called "idiopathic" cases would be discovered. lung-mapping as elsewhere herein explained is invaluable in the study of bronchiectasis. _bronchial asthma_ affords a large field for bronchoscopic study. as yet, sufficient data to afford any definite conclusions even as to the endoscopic picture of this disease have not been accumulated. of the cases seen in the bronchoscopic clinic some showed no abnormality of the bronchi in the intervals between attacks, others a chronic bronchitis. in cases studied bronchoscopically during an attack, the bronchi were found filled with bubbling secretions and the mucosa was somewhat cyanotic in color. the bronchial lumen was narrowed only as much as it would be, with the same degree of cough, in any patient not subject to asthma. the secretions were removed and the attack quickly subsided; but no influence on the recurrence of attacks was observed. it is essential that the bronchoscopic studies be made, as were these, without anesthesia, local or general, for it is known that the application of cocain or adrenalin to the larynx, or even in the nose, will, with some patients, stop the attack. when done without local anesthesia, allowance must be made for the reaction to the presence of the tube. in those cases in which other means have failed to give relief, the endobronchial application of novocain and adrenalin, orthoform, propaesin or anesthesin emulsion may be tried. cures have been reported by this treatment. argentic nitrate applied at weekly intervals has proven very efficient in some cases. associated infective disease of the bronchial mucosa brings with it the questions of immunity, allergy, anaphylaxis, and vaccine therapy; and the often present defective metabolism has to be considered. _autodrownage_.--autodrownage is the name given by the author to the drowning of the patient in his own secretions. tracheobronchial secretions in excess of the amount required to moisten the inspired air, become, in certain cases, a mechanical menace to life, unless removed. the cough reflex, forced expiration, and ciliary action, normally remove the excess. when these mechanisms are impaired, as in profound asthenia, laryngeal paralysis, laryngeal or tracheal stenosis, etc.; and especially when in addition to a mild degree of glottic stenosis or impaired laryngeal mobility, the secretions become excessive, the accumulation may literally drown the patient in his own secretions. this is illustrated frequently in influenza and arachidic bronchitis. infants cannot expectorate, and their cough reflex is exceedingly ineffective in raising secretion to the pharynx; furthermore they are easily exhausted by bechic efforts; so that age may be cited as one of the most frequent etiologic factors in the condition of autodrownage. bronchoscopic sponge-pumping (_q.v._) and bronchoscopic aspiration are quite efficient and can save any patient not afflicted with conditions that are fatal by other pathologic processes. _lues of the tracheobronchial tree_.--compared to laryngeal involvement, syphilis of the tracheobronchial tree is relatively rare. the lesions may be gummatous, ulcerative, or inflammatory, or there may be compressive granulomatous masses. hemoptysis may have its origin from a luetic ulceration. excision of fungations or of a portion of the margin of the ulceration for biopsy is advisable. the wassermann and therapeutic tests, and the elimination of tuberculosis will be required for confirmation. luetic stenoses are referred to above. _tuberculosis of the tracheobronchial tree_.--the bronchoscopic study of tuberculosis is very interesting, but only a few cases justify bronchoscopy. the subglottic infiltrations from extensions of laryngeal disease are usually of edematous appearance, though they are much more firm than in ordinary inflammatory edema. ulcerations in this region are rare, except as direct extensions of ulceration above the cord. the trachea is relatively rarely involved in tuberculosis, but we may have in the trachea the pale swelling of the early stage of a perichondritis, or the later ulceration and all the phenomena following the mixed pyogenic infections. these same conditions may exist in the bronchi. in a number of instances, the entire lumen of the bronchus was occluded by cheesy pus and debris of a peribronchial gland which had eroded through. as a rule, the mucosa of tuberculosis is pale, and the pallor is accentuated by the rather bluish streak of vessels, where these are visible. erosion through of peri-bronchial or peri-tracheal lymph masses may be associated with granulation tissue, usually of pale color, but occasionally reddish; and sometimes oozing of blood is noticed. a most common picture in tuberculosis is a broadening of the carina, which may be so marked as to obliterate the carina and to bulge inward, producing deformed lumina in both bronchi. sometimes the lumina are crescentic, the concavity of the crescent being internal, that is, toward the median line. absence of the normal anterior and downward movement of the carina on deep inspiration is almost pathognomonic of a mass at the bifurcation, and such a mass is usually tuberculous, though it may be malignant, and, very rarely, luetic. the only lesion visible in a tuberculous case may be cicatrices from healed processes. in a number of cases there has been a discharge of pus coming from the upper-lobe bronchus. [fig. 96.--the author's tampons for pulmonary hemostasis by bronchoscopic tamponade. the folded gauze is 10 cm. long; the braided silk cord 60 cm. long.] _hemoptysis_.--in cases not demonstrably tuberculous, hemoptysis may require bronchoscopic examination to determine the origin. varices or unsuspected luetic, malignant, or tuberculous lesions may be found to be the cause. it is mechanically easy to pack off one bronchus with the author's packs (fig. 96) introduced through the bronchoscope, but the advisability of doing so requires further clinical tests. _angioneurotic edema_.--angioneurotic edema manifests itself by a pale or red swollen mucosa producing stenosis of the lumen. the temporary character of the lesion and its appearance in other regions confirm the diagnosis. _scleroma of the trachea_ is characterized by infiltration of the tracheal mucosa, which greatly narrows the lumen. the infiltration may be limited in area and produce a single stricture, or it may involve the entire trachea and even close a bronchial orifice. drying and crusting of secretions renders the stenosis still more distressing. this disease is but rarely encountered in america but is not infrequent in some parts of europe. treatment consists in the prevention of crusts and their removal. limited stenotic areas may yield to bronchoscopic bouginage. urgent dyspnea calls for tracheotomy. radium and roentgenray therapy have been advised, and cure has been reported by intravenous salvarsan treatment (see article by s. shelton watkins, on scleroma in surg. gynecol. and obst., july, 1921, p. 47). _atrophic tracheitis_, with symptoms quite similar to atrophic rhinitis is a not unusual accompaniment of the nasal condition. it may also exist without nasal involvement. on tracheoscopy the mucosa is thinned, pale and dry, and is covered with patches of thick mucilaginous secretion and crusts. decomposition of secretion produces tracheal "ozena," while the accumulated crusts give rise to the sensation of a foreign body and may seriously interfere with respiration, making bronchoscopic removal imperative. the associated development of tracheal nodular enchondromata has been described. the internal administration of iodine and the intratracheal injection of bland oily solutions of menthol, guaiacol, or gomenol are helpful. [235] chapter xxx--diseases of the esophagus the more frequent causes of the one common symptom of esophageal disease, dysphagia, are included in the list given below. to avoid elaboration and to obtain maximum usefulness as a reminder, overlapping has not been eliminated. 1. anomalies. 2. esophagitis, acute. 3. esophagitis, chronic. 4. erosion. 5. ulceration. 6. trauma. 7. stricture, congenital. 8. stricture, spasmodic, including cramp of the diaphragmatic pinchcock. 9. stricture, inflammatory. 10. stricture, cicatricial. 11. dilatation, local. 12. dilatation, diffuse. 13. diverticulum. 14. compression stenosis. 15. mediastinal tumor. 16. mediastinal abscess. 17. mediastinal glandular mass. 18. aneurysm. 19. malignant neoplasm. 20. benign neoplasm. 21. tuberculosis. 22. lues. 23. actinomycosis. 24. varix. 25. angioneurotic edema. 26. hysteria. 27. functional antiperistalsis. 28. paralysis. 29. foreign body in (a) pharynx, (b) larynx, (c) trachea, (d) esophagus. [236] _diagnosis_.--the swallowing function can be studied only with the fluoroscope; esophagoscopy for diagnosis, should therefore always be preceded by a fluoroscopic study of deglutition with a barium or other opaque mixture and examination of the thoracic organs to eliminate external pressure on the esophagus as the cause of stenosis. complete physical examination and wassermann reaction are further routine preliminaries to any esophagoscopy. special laboratory tests are done as may be indicated. the physical examination is meant to include a careful examination of the lips, tongue, palate, pharynx, and a mirror examination of the larynx when age permits. _indications for esophagoscopy in disease_.--any persistent abnormal sensation or disturbance of function of the esophagus calls for esophagoscopy. vague stomach symptoms may prove to be esophageal in origin, for vomiting is often a complaint when the patient really regurgitates. _contraindications to esophagoscopy_.--in the presence of aneurysm, advanced organic disease, extensive esophageal varicosities, acute necrotic or corrosive esophagitis, esophagoscopy should not be done except for urgent reasons, such as the lodgment of a foreign body; and in this case the esophagoscopy may be postponed, if necessary, unless the patient is unable to swallow fluids. esophagoscopy should be deferred, in cases of acute esophagitis from swallowing of caustics, until sloughing has ceased and healing has strengthened the weak places. the extremes of age are not contraindications to esophagoscopy. a number of newborn infants have been esophagoscoped by the author; and he has removed foreign bodies from patients over 80 years of age. _water starvation_ makes the patient a very bad surgical subject, and is a distinct contraindication to esophagoscopy. water must be supplied by means of proctoclysis and hypodermoclysis before any endoscopic or surgical procedure is attempted. if the esophageal stenosis is not readily and quickly remediable, gastrostomy should be done immediately. _rectal feeding_ will supply water for a limited time, but for nutrient purposes rectal alimentation is dangerously inefficient. _preliminary examination of the pharynx and larynx with tongue depressor_ should always precede esophagoscopy, for any purpose, because the symptoms may be due to laryngeal or pharyngeal disease that might be overlooked in passing the esophagoscope. a high degree of esophageal stenosis results in retention in the suprajacent esophagus of the fluids which normally are continually flowing downward. the pyriform sinuses in these cases are seen with the laryngeal mirror to be filled with frothy secretion (jackson's sign of esophageal stenosis) and this secretion may sometimes be seen trickling into the larynx. this overflow into the larynx and lower air passages is often the cause of pulmonary symptoms, which are thus strictly secondary to the esophageal disease. anomalies of the esophagus _congenital esophagotracheal fistulae_ are the most frequent of the embryonic developmental errors of this organ. septic pneumonia from the entrance of fluids into the lungs usually causes death within a few weeks. _imperforate esophagus_ usually shows an upper esophageal segment ending in a blind pouch. a lower segment is usually present and may be connected with the upper segment by a fistula. _congenital stricture_ of the esophagus may be single or multiple, and may be thin and weblike, or it may extend over a third or more of the length of the esophagus. it may not become manifest until solids are added to the child's diet; often not for many months. the lodgment of an unusually large bolus of unmasticated food may set up an esophagitis the swelling of which may completely close the lumen of the congenitally narrow esophagus. it is not uncommon to meet with cases of adults who have "never swallowed as well as other people," and in whom cicatricial and spasmodic stenosis can be excluded by esophagoscopy, which demonstrates an obvious narrowing of the esophageal lumen. these cases are doubtless congenital. _webs in the upper third of the esophagus_ are best determined by the passage of a large esophagoscope which puts the esophagus on the stretch. the webs may be broken by the insertion of a closed alligator forceps, which is then withdrawn with opened blades. better still is the dilator shown in fig. 26. this retrograde dilatation is relatively safe. a silk-woven esophagoscopic bougie or the metallic tracheal bougie may be used, with proper caution. subsequent dilatation for a few times will be required to prevent a reproduction of the stenosis. _treatment of esophageal anomalies_.--gastrostomy is required in the imperforate cases. esophagoscopic bouginage is very successful in the cure of all cases of congenital stenosis. any sort of lumen can be enlarged so any well masticated food can be swallowed. careful esophagoscopic work with the bougies (fig. 40) will ultimately cure with little or no risk of mortality. any form of rapid dilatation is dangerous. congenital stenosis, if not an absolute atresia, yields more readily to esophagoscopic bouginage than cicatricial stenosis. rupture and trauma of the esophagus these may be spontaneous or may ensue from the passage of an instrument, or foreign body, or of both combined, as exemplified in the blind attempts to remove a foreign body or to push it downwards. digestion of the esophagus and perforation may result from the stagnation of regurgitated gastric juice therein. this condition sometimes occurs in profound toxic and debilitated states. rupture of the thoracic esophagus produces profound shock, fever, mediastinal emphysema, and rapid sinking. pneumothorax and empyema follow perforation into the pleural cavity. rupture of the cervical esophagus is usually followed by cervical emphysema and cervical abscess, both of which often burrow into the mediastinum along the fascial layers of the neck. lesser degrees of trauma produce esophagitis usually accompanied by fever and painful and difficult swallowing. the treatment of traumatic esophagitis consists in rest in bed, sterile liquid food, and the administration of bismuth subnitrate (about one gramme in an adult), dry on the tongue every 4 hours. rupture of the esophagus requires immediate gastrostomy to put the esophagus at rest and supply necessary alimentation. thoracotomy for drainage is required when the pleural cavity has been involved, not only for pleural secretions, but for the constant and copious esophageal leakage. it is not ordinarily realized how much normal salivary drainage passes down the esophagus. the customary treatment of shock is to be applied. no attempt should be made to remove a foreign body until the traumatic lesions have healed. this may require a number of weeks. decision as to when to remove the intruder is determined by esophagoscopic inspection. subcutaneous emphysema does not require puncture unless gaseous, or unless pus forms. in the latter event free external drainage becomes imperative. acute esophagitis this is usually of traumatic or cauterant origin. if severe or extensive, all the symptoms described under "rupture of the esophagus" may be present. the endoscopic appearances are unmistakable to anyone familiar with the appearance of mucosal inflammations. the pale, bluish pink color of the normal mucosa is replaced by a deep-red velvety swollen appearance in which individual vessels are invisible. after exudation of serum into the tissues, the color may be paler and in some instances a typical edema may be seen. this may diminish the lumen temporarily. folds of swollen mucosa crowd into the lumen if the inflammation is intense. these folds are sometimes demonstrable in the roentgenogram by the bismuth or barium in the creases between which the prominence of the folds show as islands as beautifully demonstrated by david r. bowen in one of the author's cases. if the inflammation is due to corrosives, a grayish exudate may be visible early, sloughs later. ulceration of the esophagus superficial erosions of the esophagus are by no means an uncommon accompaniment of the stagnation of food and secretions. from the irritation they produce, spastic stenosis may occur, thus constituting a vicious circle; the spasm of the esophagus increases the stagnation which in turn results in further inflammation and ultimate ulceration. healing of such ulcers may result in cicatricial contraction and organic stenosis. ulceration may follow trauma by instrument, foreign body, or corrosive. differential diagnosis of ulcer of the esophagus _simple ulcer_ requires the exclusion of lues, tuberculosis, epithelioma, endothelioma, sarcoma, and actinomycosis. simple ulcer of the esophagus is usually associated with stenosis, spastic or organic. _luetic ulcers_ commonly show a surrounding inflammatory areola, and they usually have thickened elevated edges, generally free from granulation tissue, with a pasty center not bleeding readily when sponged. the wassermann reaction may contribute to the diagnosis; but if negative, a thorough and prolonged test with mercury is imperative. it must be remembered that a person with lues may have a simple, mixed, or malignant ulceration of the esophagus, or the three lesions may even be combined. it may be in some cases possible to demonstrate the treponema pallidum in scrapings taken from the ulcer. the single _tuberculous ulcer_ is usually pale, superficial, and granular in base. if it is a continuation from more extensive extra-esophageal tuberculous ulceration, pale cauliflower granulations may be present. slight cicatrices may be seen. tuberculosis in other organs can almost always be demonstrated by roentgenographic, physical, or laboratory studies. tuberculin tests and animal injection with an emulsion of a specimen of tissue may be required. the specimen must be taken very superficially to avoid risk of perforation. _sarcomatous ulcers_ do not differ materially in appearance from those of carcinoma, but they are much more rare. _carcinomatous ulcer_ is usually characterized by the very vascular bright red zone, raised edges, fungations, granulation tissue that bleeds freely on the lightest touch, and above all, it is almost invariably situated on an infiltrated base which communicates a feeling of hardness to the pressure of sponges or the esophagoscope itself. a scar may be from the healing of an ulcer from stasis, or one of specific or precancerous character. it may be a cancerous process developing on the site of a scar, so that the presence of scar tissue does not absolutely negative malignancy. as a rule, however, scars are absent in cancer of the esophagus. the firm and sometimes prominent ridge of the crossing of the left bronchus must not be mistaken for infiltration, and the esophagoscopist must be familiar with the normal rigidity of the cricopharyngeus. [242] mixed infection gives to all esophageal ulceration a certain uniformity of appearance, so that laboratory studies of smears or histologic and bacteriologic study of tissue specimens taken from fungations or thickened edges are often required to confirm the endoscopic diagnosis. if the edges are thin and flat, the taking of a specimen involves some risk; fungations can be removed without risk; so can nodules, but care must be taken that projecting folds are not mistaken for nodules. it is always wise to push the therapeutic test with potassium iodid and especially mercury in any case of esophageal ulceration unassociated with stasis. _treatment of acute and subacute inflammation and ulceration of the esophagus_.--bismuth subnitrate in doses of about one gramme, given dry on the tongue and swallowed without water, has a local antiseptic and protective action. its antiseptic power may be enhanced by the addition of calomel to the powder, in such amount as may be tolerated by the bowels. if pain be present the combination of a grain or two of anesthesin or orthoform with the bismuth will be grateful. the local application of argyrol in 25 per cent watery solution is also of great value. the mouth and teeth are to be kept clean with a mouth wash of dakin's solution, 1 part, to peppermint water, 6 parts. the esophagus must be placed at rest as far as possible by liquid diet or, if need be, by gastrostomy. chronic esophagitis this is usually a result of stagnation of food or secretion, and will be considered under spasmodic stenosis and diffuse dilatation of the esophagus. a very marked case with local distress and pain extending through to the back was seen by the author in consultation with dr. john b. wright who had made the diagnosis. the patient was a sufferer from ankylostomiasis. [243] compression stenosis of the esophagus the esophagus may be narrowed by the pressure of any periesophageal disease or anomaly. the lesions most frequently found are: 1. goiter, cervical or thoracic. 2. malignancy of any of the intrathoracic viscera. 3. aneurysm. 4. cardiac and aortic enlargement. 5. lymphadenopathies. hodgkins' disease. leukemia. lues. tuberculosis. simple infective adenitis. 6. lordosis. 7. enlargement of the left hepatic lobe. endoscopically, compression stenosis of the esophagus is manifested by a slit-like crevice which occupies the place of the lumen and which does not open up readily before the advancing tube. the long axis of the slit is almost always at right angles to the compressive mass, if the esophageal wall be uninvolved. the covering mucosa may be normal or it may show signs of chronic inflammation. malignant compressions are characterized by their hardness when palpated with the tube. associated pressure on the recurrent laryngeal nerve often makes laryngeal paralysis coexistent. the nature of the compressive mass will require for its determination the aid of the roentgenologist, internist, and clinical laboratory. compression by the enlarged left auricle has been observed a number of times. the presence of aneurysm is a distinct contraindication to esophagoscopy for diagnosis except in case of suspected foreign body. _treatment of compressive stenosis of the esophagus_ depends upon the nature of the compressive lesion and is without the realm of endoscopy. in uncertain cases potassium iodid, and especially mercury, should always be given a thorough and prolonged trial; an occasional cure will result. esophageal intubation is indicated in all conditions except aneurysm. gastrostomy should be done early when necessary. diffuse dilatation of the esophagus this is practically always due to stagnation ectasia, which is invariably associated with either organic or "spasmodic" stricture, existing at the time of observation or at some time prior thereto. the dilating effect of the repeatedly accumulated food results in a permanent enlargement, so that the esophagus acts as the reservoir of a large funnel with a very small opening. when food is swallowed the esophagus fills, and the contents trickle slowly through the opening. gases due to fermentation increase the distension and cause substernal pressure, discomfort, and belching. a very large dilatation of the thoracic esophagus indicates spastic stenosis. cicatricial stenoses do not result in such large dilatations and the dilatation above a malignant stenosis is usually slight, probably because of its relatively shorter duration. the _treatment of diffuse esophageal dilatation_ consists in dilating the "diaphragmatic pinchcock" that is, the hiatal esophagus. chronic esophagitis is to be controlled by esophageal lavage, the regulation of the diet to liquefiable foods and the administration of bismuth subnitrate. the patient can be taught to do the lavage. the local esophagoscopic application of a small quantity of a 25 per cent watery solution of argyrol may be required for the static esophagitis. the redundancy probably never disappears; but functional and subjective cures are usually obtainable. [245] chapter xxxi--diseases of the esophagus (_continued_) spasmodic stenosis of the esophagus _etiology_.--the functional activity of the esophagus is dependent upon reflex action. the food is propulsed in a peristaltic wave by the same mechanism as, and through an innervation (auerbach and meissner plexus) similar to that which controls intestinal movements. the vagus also is directly concerned with the deglutitory act, for swallowing is impossible if both vagi are cut. anything which unduly disturbs this reflex arc may serve as an exciting cause of spasmodic stenosis. bolting of food, superficial erosions, local esophageal disease, or a small foreign body, may produce spasmodic stenosis. spasm secondary to disease of the stomach, liver, gall bladder, appendix, or other abdominal organ is clinically well recognized. a perpetuating cause in established cases is undoubtedly "nerve cell habit," and in many cases there is an underlying neurotic factor. shock as an exciting cause has been well exemplified by the number of cases of phrenospasm developing in soldiers during the world war. _cricopharyngeal spasmodic stenosis_ usually presents the subjective symptom of difficulty in starting the bolus of food downward. once started, the food passes into the stomach unimpeded. regurgitation, if it occurs, is immediate. the condition consists in a tonic contraction, ahead of the bolus, of the circular fibers of the inferior constrictor known as the cricopharyngeus muscle, or in a failure of this muscle to relax so as to allow the bolus to pass. in either case the disorder may be secondary to an organic lesion. local malignant disease or foreign bodies may be the cause. globus hystericus, "lump in the throat," and the sense of constriction and choking during emotion are due to the same spasmodic condition. _diagnosis_.--at esophagoscopy there will be found marked exaggeration of the usual spasm which occurs at the cricopharyngeus during the introduction of the tube. the lumen may assume various shapes, or be so tightly closed that the folds form a mammilliform projection in the center. if the spasm gradually yields, and a full-sized esophagoscope passes without further resistance, it may be stated that the esophagus is of normal calibre, and a diagnosis of spasmodic stenosis can be made. considerable experience is required to distinguish between normal and pathologic spasm in an unanesthetized individual. to the less experienced esophagoscopist, examination under ether anesthesia is recommended. deep anesthesia will relax the normal cricopharyngeal reflex closure as well as any abnormal spasm, thus assisting in the differentiation between an organic stricture and one of functional character. under deep general anesthesia, however, it is impossible to differentiate between the normal reflex and a spasmodic condition, since both are abolished. many cases of intermittent esophageal stenosis supposed to be spasmodic are due to organic narrowness of lumen plus lodgement of food, obstructive in itself and in the esophagitis resulting from its presence. the organic narrowing, congenital or pathologic, is readily recognizable esophagoscopically. _treatment_.--the fundamental cause of the disturbance of the reflex should be searched for, and treated according to its nature. purely functional cases are often cured by the passage of a large esophagoscope. recurrences may require similar treatment. [247] functional hiatal stenosis. hiatal esophagismus. phrenospasm, diaphragmatic pinchcock stenosis. (so-called cardiospasm) there is no sphincteric muscular arrangement at the cardiac orifice of the esophagus, so that spasmodic stenosis at this level is not possible and the term cardiospasm is, therefore, a misnomer. it was first demonstrated by the author that in so-called cardiospasm the functional closure of the esophagus occurred at the diaphragmatic level, and that it was due to the "diaphragmatic pinchcock." anatomical studies have corroborated this finding by demonstrating a definite sphincteric mechanism consisting of muscle bands springing from the crura of the diaphragm and surrounding the esophagus at the under surface of the hiatus. an inspection of the cadaveric diaphragm from below will demonstrate an arrangement like double shears admirably adapted to this "pinchcock" action. further confirmation is the fact that all dilatation of the esophagus incident to spasm at its lower extremity is situated above the diaphragm. in passing it may be stated that the pinchcock action, plus the kinking of the esophagus normally prevents regurgitation when a man with a full stomach "stands on his head" or inverts his body. for the upward escape of food from the stomach an involuntary co-ordinated antiperistaltic cycle is necessary. the dilatation resulting from phrenospasm may reach great size (fig. 96a), and the capacity of the sac may be as much as two liters. while the esophagus is usually dilated, the stomach on the other hand is often contracted, largely from lack of distention by food, but possibly also because of a spastic state due to the same causes as the phrenospasm. recently mosher has demonstrated that hepatic abnormality may furnish an organic cause in many cases formerly considered spasmodic. the _symptoms of hiatal esophagismus_ are variable in degree. substernal distress, with a feeling of fullness and pressure followed by eructations of gas and regurgitation of food within a period of a quarter of an hour to several hours after eating, are present. if the esophageal dilatation be great, regurgitation may occur only after an accumulation of several days, when large quantities of stale food will be expelled. the general nutrition is impaired, and there is usually the history of weight loss to a certain level at which it is maintained with but slight variation. this is explained by the trickling of liquified food from the esophageal reservoir into the stomach as the spasm intermittently relaxes, this occurring usually before a serious state of inanition supervenes. at times the hiatal spasms are extremely violent and painful, the pain being referred from the xiphoid region to the back, or upward into the neck. patients are often conscious of the times of patulency of the esophagus; they will know the esophagus to be open and will eat without hesitation, or will refuse food with the certain knowledge that it will not pass into the stomach. periods of remission of symptoms for months and years are noted. the neurotic character of the lesion in some cases is evidenced by the occasionally sudden and startling cures following a single dilatation, as well as by the tendency to relapse when the individual is subject to what is for him undue nervous tension. in a very few cases, with patients of rather a stolid type, all neurotic tendencies seem to be absent. the _diagnosis of hiatal esophagismus_ requires the exclusion of local organic esophageal lesions. in the typical case with marked dilatation, the esophagoscopic findings are diagnostic. a white, pasty, macerated mucosa, and normally contracted hiatus esophageus which when found permits the large esophagoscope to pass into the stomach, will be recognized as characteristic by anyone who has seen the condition. in the cases with but little esophageal distension the diagnosis is confirmed by the constancy of the obstruction to a barium mixture at the phrenic level, while at esophagoscopy the usual resistance at the hiatus esophageus is found not to be increased, and no other local lesion is found as the esophagoscope enters the stomach. it is the failure of the diaphragmatic pinchcock to open, as in the normal deglutitory cycle, rather than a spasmodic tightness, that obstructs the food. the presence of organic stenosis at the hiatus may remove the case altogether from the spasmodic class, or a cicatricial or infiltrated narrowing may be the result of static esophagitis. a compressive stenosis due to hepatic abnormality may simulate spasmodic stenosis as shown by mosher, who believes that 75 per cent of so-called cardiospasms are organic. _treatment of hiatal esophagismus (so-called cardiospasm)_ consists in the over-dilatation of the "diaphragmatic pinchcock" or hiatus esophageus, and in proper remedial measures for the removal of the underlying neurosis. the simple passage of the esophagoscope suffices to cure some cases. further dilatation by endoscopic guidance may be obtained by the introduction of mosher's divulsor through the esophagoscope, by which accurate placement is obtained. the distension should not usually exceed 25 mm. numerous water and air bags have been devised for stretching the hiatus, and excellent results have been obtained by their use. possibly some of the cures have been due to the dilatation of organic lesions, or to the crowding back of an enlarged malposed, or otherwise abnormal left lobe of the liver, which mosher has shown to be an etiologic factor. certain cases prove very obstinate of cure, and require esophageal lavage for the esophagitis, and feedings through the stomach tube to increase nutrition and to dilate the contracted stomach. gastrostomy for feeding rarely becomes necessary, for a stomach tube can always be placed with the esophagoscope if it will not pass otherwise. retrograde dilatation with the fingers through a gastrostomy opening has been done, but seems hardly warranted in view of the excellent results obtainable from above. instructions should be given concerning the proper mastication of food, and during treatment the frequent partaking of small quantities of liquid foods is recommended. liquids and foods should be neither hot nor cold. the neurologist should be consulted in cases deemed neurotic. [96a.-functional hiatal stenosis. cramp of the diaphragmatic pinchcock (so-called cardiospasm).] endocrine imbalance should be investigated and treated, as urged by macnab. _esophageal antiperistalsis_ is the name given by the author to a heretofore undescribed disease associated with regurgitation of food from the esophagus, the food not having reached the stomach. it may be continuous or paroxysmal and may be of so serious a degree as to threaten starvation. the best treatment in severe cases is gastrostomy to put the esophagus at rest. milder cases get well under liquid diet, rest in bed, endocrine therapy, cure of associated abdominal disease, etcetera. [251] chapter xxxii--diseases of the esophagus (_continued_) cicatricial stenosis of the esophagus _etiology_.--the accidental swallowing of caustic alkali in solutions of lye or proprietary washing and cleansing powders, is the most frequent cause of cicatricial stenosis. commercial lye preparations are about 95 per cent sodium hydroxide. the cleansing and washing powders contain from eight to fifty per cent of caustic alkali, usually soda ash, and are sold by grocers everywhere. the labels on their containers not only give no warning of the dangerous nature of the contents nor antidotal advice, but have such directly misleading statements as : "will not injure the most delicate fabric," "will not injure the hands," etc. utensils used to measure or dissolve the powders are afterward used for drinking, without rinsing, and thus the residue of the powder remaining is swallowed in strong solution. at other times solutions of lye are drunk in mistake for water, coffee, or wine. these entirely preventable accidents would be rare if they were as conspicuously labelled "poison" as is required by law in the case of these and any other poisons, when sold by druggists. the necessity for such labelling is even greater with the lye preparations because they go into the kitchen, whereas the drugs go to the medicine shelf, out of the reach of children. "household ammonia," "salts of tartar" (potassium carbonate), "washing soda" (sodium carbonate), mercuric chloride, and strong acids are also, though less frequently, the cause of cicatricial esophageal stricture. tuberculosis, lues, scarlet fever, diphtheria, enteric fever and pyogenic conditions may produce ulceration followed by cicatrices of the esophagus. spasmodic stenosis with its consequent esophagitis and erosions, and, later, secondary pyogenic infection, may result in serious cicatrices. peptic ulcer of the lower esophagus may be a cause. the prolonged sojourn of a foreign body is likely to result in cicatricial narrowing. [fig. 97.--schematic illustration of a series of eccentric strictures with interstrictural sacculations, in the esophagus of a boy aged four years. the strictures were divulsed seriatim from above downward with the divulsor, the esophageal wall, d, being moved sidewise to the position of the dotted line by means of a small esophagoscope inserted through the upper stricture, a, after divulsion of the latter.] _location of cicatricial esophageal strictures_.--the strictures are often multiple and their lumina are rarely either central or concentric (fig. 97). in order of frequency the sites of cicatricial stenosis are: 1. at the crossing of the left bronchus; 2. in the region of the cricopharyngeus; 3. at the hiatal level. stricture at the cardia has rarely been encountered in the bronchoscopic clinic. stenosis of the pylorus has been noted, but is rare. _prognosis_.--spontaneous recovery from cicatricial stenosis probably never occurs, and the mortality of untreated small lumen strictures is very high. blind methods of dilatation are almost certain to result in death from perforation of the esophageal wall, because some pressure is necessary to dilate a stricture, and the point of the bougie, not being under guidance of the eye, is certain at sometime or other to be engaged in a pocket instead of in the stricture. pressure then results in perforation of the bottom of the pocket (fig. 98). this accident is contributed to by dilatation with the wrinkled, scarred floor which usually develops above the stricture. rapid divulsion and internal esophagotomy are mechanically very easily and accurately done through the esophagoscope, and would yield a few prompt cures; but the mortality would be very high. under certain circumstances, to be explained below, gentle divulsion of the proximal one of a series of strictures has to be done. with proper precautions and a gentle hand, the risk is slight. under esophagoscopic bouginage the prognosis is favorable as to ultimate cure, the duration of the treatment varying with the number of strictures, the tightness, and the extent of the fibrous tissue-changes in the esophageal wall. mortality from the endoscopic procedure is almost nil, and if gastrostomy is done early in the tightly stenosed cases, ultimate cure may be confidently expected with careful though prolonged treatment. [fig. 98.--schema illustrating the mechanism of perforation by blind bouginage. on encountering resilient resistance the operator, having a false conception, pushes on the bougie. perforation results because in reality the bougie is in a pocket of the suprastrictural eccentric dilatation.] _symptoms_.--dysphagia, regurgitation, distress after eating, and loss of weight, vary with the degree of the stenosis. the intermittency of the symptoms is sometimes confusing, for the lodgment of relatively large particles of food often simulates a spasmodic stenosis, and in fact there is often an element of spasm which holds the foreign body in the strictured area until it relaxes. static esophagitis results in a swelling of the esophageal walls and a narrowing of the lumen, so that swallowing is more or less troublesome until the esophagitis subsides. _esophagoscopic appearances of cicatricial stenosis_.--the color of the cicatricial area is usually paler than the normal mucosa. the scars may be very white and elevated, or they may be flush with the normal mucosa, or even depressed. occasionally the cicatrix is annular, but more often it is eccentric and involves only a part of the circumference of the wall. if the amount of scar tissue is small, the lumen maintains its mobility; opens and closes during respiration, cough, and vomiturition. between two strictures there is often a pouch containing food remnants. it is rarely possible to see the lumen of the second stricture, because it is usually eccentric to the first. stagnation of food results in superjacent dilatation and esophagitis. erosions and ulcerations which follow the stagnation esophagitis increase the cicatricial stenosis in their healing. _differential diagnosis_.--when the underlying condition is masked by inflammation and ulceration, these lesions must be removed by frequent lavage, the administration of bismuth subnitrate with the occasional addition of calomel powder, and the limitation of the diet to strained liquids. the cicatricial nature of the stenosis can then be studied to better advantage. in most cases the cicatrices are unmistakably conspicuous. spasmodic stenoses are differentiated by the absence of cicatrices and the yielding of the stenosis to gentle but continuous pressure of the esophagoscope. while it is possible that spasmodic stenosis may supplement cicatricial stenosis, it is certainly exceedingly rare. nearly all of the occasions in which a temporary increase of the stenosis in a cicatricial case is attributed to an element of spasm, the real cause of the intermittency is not spasm but obstruction caused by food. this occurs in three ways: 1. actual "corking" of the strictured lumen by a fragment of food, in which case intermittency may be due to partial regurgitation of the "corking" mass with subsequent sinking tightly into the stricture. 2. the "cork" may dissolve and pass on through to be later replaced by another. 3. reactionary swelling of the esophageal mucosa due to stagnation. here again the obstruction may be prolonged, or it may be quite intermittent, due to a valve-like action of the swollen mucosal surfaces or folds intermittently coming in contact. cancerous stenosis is accompanied by infiltration of the periesophageal tissue, and usually by projecting bleeding fungations. cancer may, however, develop on a cicatrix, favored no doubt by chronic inflammation in tissue of low resistance. compression stenosis of the esophagus is characterized by the sudden transition of the lumen to a linear or crescentic outline, while the covering mucosa is normal unless esophagitis be present. the compressive mass can be detected by the sensation transmitted to the touch by the esophagoscope. _treatment_.--blind bouginage should be discarded as an obsolete and very dangerous procedure. if the stenosis be so great as to interfere with the ingestion of the required amount of liquids, gastrostomy should be done at once and esophagoscopic treatment postponed until water hunger has been relieved. gastrostomy aids in the treatment by putting the esophagus at rest, and by affording the means of maintaining a high degree of nutrition unhampered by the variability or efficiency of the swallowing function. careful diet and gentle treatment will, however, usually avoid gastrostomy. the diet in the gastrostomy-fed patients should be as varied as in oral alimentation; even solids of the consistency of mashed potatoes, if previously forced through a wire gauze strainer, may be forced through the tube with a glass injector. liquids and readily liquefiable foods are to be given the non-gastrostomized patient, solids being added when demonstrated that no stagnation above the stricture occurs. thorough mastication and the slow partaking of small quantities at a time are imperative. should food accumulation occur, the esophagus should be emptied by regurgitation, following which a glassful of warm sodium bicarbonate solution is to be taken, and this also regurgitated if it does not go through promptly. the esophagus is thus lavaged and emptied. in all these cases, whether being fed through the mouth or the gastrostomic tube, it is very important to remember that milk and eggs are not a complete dietary. a pediatrist should be consulted. prof. graham has saved the lives of many children by solving the nutritive problems in the cases at the bronchoscopic clinic. fruit and vegetable juices are necessary. vegetable soups and mashed fruits should be strained through a wire gauze coffee strainer. if the saliva is spat out by the child because it will not go through the stricture the child should be taught to spit the saliva into the funnel of the abdominal tube. this method of improving nutrition was discovered by miss groves at the bronchoscopic clinic. _esophagoscopic bouginage_ with the author's silk-woven steel-shank endoscopic bougies (fig. 40) has proven the safest and most successful method of treatment. the strictured lumen is to be centered in the esophagoscopic field, and three successively increasing sizes of bougies are used under direct vision. larger and larger bougies are used at the successive treatments which are given at intervals of from four to seven days. no anesthesia, general or local, is used for esophagoscopic bouginage. the tightness of the grasping of the bougie by the stricture on withdrawal, determines the limitation of sizes to be used. when the upper stricture is dilated, lower ones in the series are taken seriatim. if concentric, two or more closely situated strictures may be simultaneously dilated. for the use of bougies of the larger sizes, the special esophagoscopes with both the light-carrier canal and the drainage canal outside the lumen of the tube are needed. functional cure is obtained with a relatively small lumen at the point of stenosis. a lumen of 7 mm. will allow the passage of any well masticated food. it is unwise and unsafe to attempt to restore the lumen to its normal anatomic size. in cicatricial stricture cases it is advisable to examine the esophagus at monthly periods for a time after a functional cure has been obtained, in order that tendency to recurrence may be early detected. _divulsion_ of an upper stricture may be deemed advisable in order to reach others lower down, especially in cases of multiple eccentric strictures (fig. 97). this procedure is best done with the author's esophagoscopic divulser, accurately placed by means of the esophagoscope; but divulsion requires the utmost care, and a gentle hand. even then it is not so safe as esophagoscopic bouginage. _internal esophagotomy_ by the string-cutting instruments and esophagotome are relatively dangerous methods, and perhaps yield in the end no quicker results than the slower and safe bouginage per tubam. _electrolysis_ has been used with varying results in the treatment of cicatricial stenosis. _thermic bouginage_ with electrically heated bougies has been found useful in some cases by dean and imperatori. [258] _string-swallowing_, with the passage of olives threaded over the string has yielded good results in the hands of some operators. the string may be used to pull up dilators in increasing sizes, introduced through a gastrostomic fistula. the string stretched across the stomach from the cardia to the pylorus, is fished out with the author's pillar retractor, or is found with the retrograde esophagoscope (fig. 43). the string is attached to a dilator (fig. 35), and a fresh string is pulled in to replace the one pulled out. this is the safest of the blind methods. it is rarely possible to get a child under two years of age to swallow and tolerate a string. it is better after each treatment to draw the upper end of the string through the nose, as it is not so likely to be chewed off and is less annoying. with the esophagoscope, the string is not necessary, because the lumen of the stricture can be exposed to view by the esophagoscope. _retrograde esophagoscopy_ through a gastrostomy wound offers some advantages over peroral treatment; but unless the gastrostomy is high, the procedure is undoubtedly more difficult. the approach to the lowest stricture from below is usually funnel shaped and free from dilatation and redundancy. it must be remembered the stricture seen from below may not be the same one seen from above. roentgenray examination with barium mixture or esophagoscopes simultaneously in situ above and below are useful in the study of such cases. _impermeable strictures_ of the cervical esophagus are amenable to external esophagotomy, with plastic reformation of the esophagus. those in the middle third have not been successfully treated by surgical methods, though various ingenious operations for the formation of an extrathoracic esophagus have been suggested as means of securing relief. impermeable strictures of the lower third can with reasonable safety be treated by the brenneman method, which consists in passing the esophagoscope down to the stricture while the surgeon, inserting his finger up into the esophagus from the stomach, can feel the end of the esophagoscope. an incision through the tissue barrier is then made from below, passing the knife along the finger as a guide. a soft rubber stomach-tube is pulled up from below and left in situ, being replaced at intervals by a fresh one, pulled up from the stomach, until epithelialization of the new lumen is complete. catheters are used in children. in replacing the catheter or stomach tube the fresh one is attached to the old one by stitching in a loop of braided silk. frequent esophagoscopic bouginage will be required to maintain the more or less fistulous lumen until it is epithelialized, and in occasional cases, for a long time thereafter. in cases of absolute atresia the saliva does not reach the stomach. no one realizes the quantity of normal salivary drainage, nor its importance in nutritive processes. oral insalivation is of little consequence compared to esophagogastric drainage. gastrostomized children with absolute atresia of the esophagus do not thrive unless they regurgitate the salivary accumulations into the funnel of the gastrostomic feeding tube. this has been abundantly proven by observations at the bronchoscopic clinic. my attention was first called to this clinical fact by miss frances groves who has charge of these cases. _intubation of the esophagus_ with soft rubber tubes has occasionally proven useful. [260] chapter xxxiii--diseases of the esophagus (_continued_) diverticulum of the esophagus diverticula may, and usually do, consist in a pouching by herniation, of the whole thickness of the esophageal wall; or they may be herniations of the mucosa between the muscular layers. they are classified according to their etiology, as traction and pulsion diverticula. [fig. 99.--traction diverticulum of the esophagus rendered visible in the roentgenogram by a swallowed opaque mixture. case of h. w. dachtler, am. journ. roentgenology.] _traction diverticulum of the esophagus_ (fig. 99) is a rare condition, usually occurring in the thorax, and as a rule constituting a one-sided enlargement of the gullet rather than a true pouch formation. it is supposed to be formed by the pulling during cough, respiration, and swallowing, on localized adhesions of the esophagus to periesophageal structures, such as inflammatory peribronchial glands. _diagnosis_ is often incidental to examination of the gastrointestinal tract for other conditions, because traction diverticula usually cause no symptoms. unless a very large esophagoscope be used, a traction diverticulum may easily be overlooked in the mucosal folds. careful lateral search, however, will reveal the dilatation, and the localized periesophageal fixation may be demonstrated. the subdiverticular esophagus is readily followed, its lumen opening during inspiration unless very close to the diaphragm, which is very rare. perhaps most cases will be discovered by the roentgenologist. it has been said that traction diverticula are more readily demonstrated in the roentgenologic examination, if the patient be placed with pelvis elevated. _pulsion diverticulum of the esophagus_ is an acquired hernia of the mucosa between the circular and oblique fibers of the inferior constrictor muscle of the pharynx. a congenital anatomic basic factor in etiology probably exists. the pouching develops in the middle part of the posterior wall, between the orbicular and oblique fibers of the cricopharyngeus muscle, at which point there is a gap, leaving the mucosa supported only by a not very resistant fascia (fig. 100). when small, the sac is in the midline, but with increase in size, it presents either to the right or the left side, commonly the latter. the sac may be very small, or it may be sufficiently large to hold a pint or more, and to cause the neck to bulge when filled. when large, the pouch extends into the mediastinum. it will be seen that anatomically the pulsion diverticulum has its origin in the pharynx; the symptoms, however, are referable to the esophagus and the subdiverticular esophagus is stenosed by compression of the pouch; therefore, it is properly classified as an esophageal disease. [fig. 100.--schema illustrative of the etiology of pressure diverticula. o, oblique fibers of the cricopharyngeus attached to the thyroid cartilage, t. the fundiform fibers, f, encircle the mouth of the esophagus. between the two sets of fibers is a gap in the support of the esophageal wall, through which the wall herniates owing to the pressure of food propelled by the oblique fibers, o, advance of the bolus being resisted by spasmodic contraction of the orbicular fibers, f.] _etiology_.--pressure diverticula occur after middle life, and more often in men than in women. the hasty swallowing of unmasticated food, too large a bolus, defective or artificial teeth, flaccidity of tissues, and spasm of the cricopharyngeus muscle, are etiologic factors. cicatricial stenosis below the level of the inferior constrictor is a contributory cause in some cases. _prognosis_.--after the pouch is formed, it steadily increases in size, since the swallowed food first fills and distends the sac before the overflow passes down the esophagus. when a pendulous sac becomes filled with food, it presses on the subdiverticular esophagus, and produces compression stenosis; so that there exists a "vicious circle." the enlargement of the sac produces increasing stenosis with consequent further distension of the pouch. this explains the clinically observed fact, that unless treated, pulsion diverticula increase progressively in size, and consequently in distressing symptoms. the sac becomes so large in some cases as to contribute to the occurrence of cerebral apoplexy by interference with venous return. practically all cases can be cured by radical operation. the operative mortality varies with the age, state of nutrition, and general health of the patient. in general it may be said to have a mortality of at least 10 per cent, largely due to the fact that most cases are poor surgical subjects. recurrences after radical operation are due to a persistence of the original causes, i.e., bolting of food; stenosis, spasmodic or organic, of the esophageal lumen; and weakness in the support of the esophageal wall, which, unsupported, has little strength of its own. _symptoms_.--dysphagia, regurgitation, a gurgling sound and subjective bubbling sensation on swallowing, sour odor to the breath, and cough, are the chief symptoms. with larger pouches, emaciation, pressure sensation in the neck and upper mediastinum, and the presence of a mass in the neck when the sac is filled, are present. tracheal compression by the filled pouch may produce dyspnea. the sac may be emptied by pressure on the neck, this means of relief being often discovered by the patient. the sac sometimes spontaneously empties itself by contraction of its enveloping muscular layer, and one of the most annoying symptoms is the paroxysm of coughing, waking the patient, when during the relaxation of sleep the sac empties itself into the pharynx and some of its contents are aspirated into the larynx. there are no pathognomonic symptoms. those recited are common to other forms of esophageal stenosis, and are urgent indications for diagnostic esophagoscopy. _diagnosis_.--roentgenray study with barium mixtures, is the first step in the diagnosis (fig. 101). this is to be followed by diagnostic esophagoscopy. malignant, spasmodic, cicatricial, and compression stenosis are to be excluded by esophagoscopic appearances. aneurysm is to be eliminated by the usual means. the boyce sign is almost invariably present, and is diagnostic. it is elicited by telling the patient to swallow, which action imprisons air in the sac. the imprisoned air is forced out by finger-pressure on the neck, over the sac. the exit of the air bubble produces a gurgling sound audible at the open mouth of the patient. _esophagoscopic appearances in pulsion diverticulum_.--the esophagoscope will without difficulty enter the mouth of the sac which is really the whole bottom of the pharynx, and will be arrested by the blind end of the pouch, the depth of which may be from 4 to 10 cm. in some cases the bottom of the pouch is in the mediastinum. the walls are often pasty, and may be eroded, or ulcerated, and they may show vessels or cicatrices. on withdrawing the tube and searching the anterior wall, the subdiverticular slit-like opening of the esophagus will be found, though perhaps not always easily. the esophageal speculum will be found particularly useful in exposing the subdiverticular orifice, and through this a small esophagoscope may be passed into the esophagus, thus completing the diagnosis. care must be exercised not to perforate the bottom of the diverticular pouch by pressure with the esophagoscope or esophageal speculum. the walls of the sac are surprisingly thin. [fig. 101.--pulsion diverticulum filled with bismuth mixture in a man of fifty years.] _treatment of pulsion diverticulum_.--if the pouch is small, the subdiverticular esophageal orifice may be dilated with esophagoscopic bougies, thus overcoming the etiologic factor of spastic or organic stenosis. the redundancy remains, however, though the symptoms may be relieved. cutting the common wall between the esophagus and the sac by means of scissors passed through the endoscopic tube, has been successfully done by mosher. various methods of external operation have been devised, among which are: (1) freeing the sac through an external cervical incision and suturing its fundus upward against the pharynx, which has proved successful in some cases. (2) inversion of the sac into the pharynx and suture of the mouth of the pouch. in a case so treated the pouch was blown out again during a fit of sneezing eight months after operation. (3) plication of the walls of the sac by catgut sutures, as in the matas obliterative operation for aneurysm. (4) freeing and removing the sac, with suture of the esophageal wound. (5) removal of the sac by a two-stage operation, in which method the initial step is the deliverance of the sac into the cervical wound, where it remains surrounded by gauze packing until adhesions have walled off the mediastinum. the work is completed by cutting off the sac and either suturing the esophageal wound or touching it with the cautery, and allowing it to heal by granulation. external exposure and amputation of the sac has been more frequently done than any other operation. unless the pouch is large, it is extremely difficult to find after the surgeon has exposed the esophagus, for the reasons that at operation it is empty and that when the adhesions about it are removed the walls of the sac contract. after removal, the sac is disappointingly small as compared with its previous size in the roentgenogram, which shows it distended with opaque material. it has been the chagrin of skilled surgeons to find the diverticulum present functionally and roentgenographically precisely the same as before the performance of the very trying and difficult operation. the time of operation may be shortened at least by one-half by the aid of the esophagoscopist in the gaub-jackson operation. intratracheally insufflated ether is the anesthesia of choice. after the surgeon has exposed the esophagus by dissection, the endoscopist introduces the esophagoscope into the sac, and delivers it into the wound, while the surgeon frees it from adhesions. the esophagoscope is now withdrawn from the pouch and entered into the esophagus proper, below the diverticulum, while the surgeon cuts off the hernial sac and sutures the esophagopharyngeal wound over the esophagoscope. the presence of the esophagoscope prevents too tight suture and possible narrowing of the lumen (fig. 102). [fig. 102.--schematic representation of esophagoscopic aid in the excision of a diverticulum in the gaub-jackson operation. at a the esophagoscope is represented in the bottom of the pouch after the surgeon has cut down to where he can feel the esophagoscope. then the esophagoscopist causes the pouch to protrude as shown by the dotted line at b. after the surgeon has dissected the sac entirely loose from its surroundings, traction is made upon the sac as shown at h and the esophagoscope is inserted down the lumen of the esophagus as shown at c. the esophagoscope now occupies the lumen which the patient will need for swallowing. it only remains for the surgeon to remove the redundancy, without risk of removing any of the normal wall. the esophagoscope here shown is of the form squarely cut off at the end. the standard form of instrument with slanted end will serve as well.] _after-care_.--feeding may be carried on by the placing of a small nasal feeding tube into the stomach at the time of operation. gastrostomy for feeding as a preliminary to the esophageal operation has been suggested, and is certainly ideal from the viewpoint of nutrition and esophageal rest. the decision of its performance may perhaps be best made by the patient himself. should leakage through the neck occur, the fistula should be flushed by the intake of sterile water by mouth. oral sepsis should, of course, be treated before operation and combated after operation by frequent brushing of the teeth and rinsing of the mouth with dakin's solution, one part, to ten parts of peppermint water. a postoperative barium roentgenogram should be made in every case as a matter of record and to make certain the proper functioning of the esophagus. [268] chapter xxxiv--diseases of the esophagus (_continued_) paralysis of the esophagus the passage of liquids and solids through the esophagus is a purely muscular act, controlled, after the propulsive usually voluntary start given to the bolus by the inferior constrictor, by a reflex arc having connection with the central nervous system through the vagus nerve. gravity plays little or no part in the act of deglutition, and alone will not carry food or drink to the stomach. paralysis of the esophagus may be said to be motor or sensory. it is rarely if ever unassociated with like lesions of contiguous organs. _motor paralysis of the esophagus_ is first manifested by inability to swallow. this is associated with the accumulation of secretion in the pyriform sinuses (the author's sign of esophageal stenosis) which overflows into the larynx and incites violent coughing. motor paralysis may affect the constrictors or the esophageal muscular fibers or both. _sensory paralysis of the esophagus_ by breaking the continuity of the reflex arc, may so impair the peristaltic movements as to produce aphagia. the same filling of the pyriform sinuses will be noted, but as the larynx is usually anesthetic also, it may be that no cough is produced when secretions overflow into it. _etiology_.--1. toxic paralysis as in diphtheria. 2. functional paralysis as in hysteria. 3. peripheral paralysis from neuritis. 4. central paralysis, usually of bulbar origin. embolism or thrombosis of the posterior cerebral artery is a reported cause in two cases. lues is always to be excluded as the fundamental factor in the groups 3 and 4. esophageal paralysis is not uncommon in myasthenia gravis. _esophagoscopic findings_ are those of absence of the normal resistance at the cricopharyngeus, flaccidity and lack of sensation of the esophageal walls, and perhaps adherence of particles of food to the folds. the hiatal contraction is usually that normally encountered, for this is accomplished by the diaphragmatic musculature. in paralysis of sensation, the reflexes of coughing, vomiturition and vomiting are obtunded. _diagnosis_.--hysteria must not be decided upon as the cause of dysphagia, until after esophagoscopy has eliminated paralysis. dysphagia after recent diphtheria should suggest paralysis of the esophagus. the larynx, lips, tongue, and pharynx also, are usually paralyzed in esophageal paralysis of bulbar origin. the absence of the cricopharyngeal resistance to the esophagoscope passed without anesthesia, general or local, is diagnostic. _treatment_.--the internist and neurologist should govern the basic treatment. nutrition can be maintained by feeding with the stomach-tube, which meets no resistance to its passage. should this be contraindicated by ulceration of the esophagus, gastrostomy should be done. lues of the esophagus _esophageal syphilis_ is a rather rare affection, and may show itself as a mucous plaque, a gumma, an ulceration, or a cicatrix. cicatricial stenosis developing late in life without history of the swallowing of escharotics or ulcerative lesions is strongly suggestive of syphilis, though the late manifestation of a congenital stenosis is a possibility. _esophagoscopic appearances_ of lues are not always characteristic. as in any ulcerative lesion, the inflammatory changes of mixed infections mask the basic nature. the mucous plaque has the same appearance as one situated on the velum, and gummata resemble those seen in the mucosa elsewhere. there is nothing characteristic in luetic cicatrices. _the diagnosis_ of luetic lesions of the esophagus, therefore, depends upon the history, presence of luetic lesions elsewhere, the serologic reaction, therapeutic test, examination of tissue, and the demonstration of the treponema pallidum. the therapeutic test by prolonged saturation of the system with mercury is imperative in all suspected cases and no other negative result should be deemed sufficient. _the treatment_ of luetic esophagitis is systemic, not local. luetic cicatrices contract strongly, and are very resistant to treatment, so that esophagoscopic bouginage should be begun as early as possible after the healing of a luetic ulceration, in order to prevent stenosis. a silk-woven endoscopic bougie placed in position by ocular guidance, and left _in situ_ for from half to one hour daily, may prevent severe contraction, if used early in the stage of cicatrization. prolonged treatment is required for the cure of established luetic cicatricial stenosis. if gastrostomy has been done retrograde bouginage (fig. 35) may be used. tuberculosis of the esophagus _esophageal tuberculosis_ is not commonly met, but is probably not infrequently associated with the dysphagia of tuberculous laryngitis. it may rarely occur as a primary infection, but usually the esophagus is involved in an extension from a tuberculous process in the larynx, mediastinal lymphatics, pleura, bronchi, or lungs. primary lesions appear as superficial erosions or ulcerations, with a surrounding yellowish granular zone, or the granules may alone be present. the mucosa in tuberculous lesions is usually pallid, the absence of vascularity being marked. invasion from the periesophageal organs produces more or less localized compression and fixation of the esophagus. the character of open ulceration is modified by the mixed infections. healed tuberculous lesions, sometimes resulting from the evacuation of tuberculous mediastinal lymph nodes into the esophagus may be encountered. the local fixation and cicatricial contraction may be the site of a traction diverticulum. tuberculous esophago-bronchial fistulae are occasionally seen. _diagnosis_, to be certain, requires the demonstration of the tubercule bacilli and the characteristic cell accumulation of the tubercle in a specimen of tissue removed from the lesion. actinomycosis must be excluded, and the possibility of mixed luetic and tuberculous lesions is to be kept in mind. post-tuberculous cicatrices have no recognizable characteristics. _treatment_.--the maintenance of nutrition to the highest degree, and the institution of a strict antituberculous regime are demanded. local applications are of no avail. gastrostomy for feeding should be done if dysphagia be severe, and has the advantage of putting the esophagus at rest. the passage of a stomach-tube for feeding purposes may be done, but it is often painful, and is dangerous in the presence of ulceration. pain is not marked if the lesion be limited to the esophagus, though if it is present orthoform, anesthesin, or apothesin, in powder form, swallowed dry, may prove helpful. varix and angioma of the esophagus these lesions are sometimes the cause of esophageal hemorrhage, the regurgitated blood being bright red, and alkaline in reaction, in contradistinction to the acid "coffee ground" blood of gastric origin. esophageal varices may coexist with the common dilatation of the venous system in which the veins of the rectum, scrotum, and legs are most conspicuously affected. cirrhosis and cancer of the liver may, by interference with the portal circulation, produce dilatation of the veins in the lower third of the esophagus. angioma of the esophagus is amenable to radium treatment. actinomycosis of the esophagus _esophageal actinomycosis_ has been autoptically discovered. its diagnosis, and differentiation from tuberculosis, would probably rest upon the microscopic study of tissue removed esophagoscopically, though as yet no such case has been reported. angioneurotic edema _angioneurotic edema_ involving the esophagus, may produce intermittent and transient dysphagia. the lesions are rarely limited to the esophagus alone; they may occur in any portion of the gastrointestinal, genitourinary, or respiratory tracts, and concomitant cutaneous manifestations usually render the diagnosis clear. the treatment is general. deviation of the esophagus _deviation of the esophagus_ may be marked in the presence of a deformed vertebral column, though dysphagia is a very uncommon symptom. the lack of esophageal symptoms in deviation of spinal production is probably explained by the longitudinal shortening of the spine which accompanies the deflection. compression stenosis of the esophagus is commonly associated with deviations produced by a thoracic mass.

[275] like many other valuable diagnostic means, gastroscopy is very valuable in its positive findings. negative results are entitled to little weight except as to the explorable area. the gastroscopist working in conjunction with the abdominal surgeon should be able to render him invaluable assistance in his work on the stomach. the surgeon with his gloved hand in the abdomen, by manipulating suspected areas of the stomach in front of the tube-mouth can receive immediately a report of its interior appearance, whether cancerous, ulcerated, hemorrhagic, etc. _lens-system ballooning gastroscopy_ may possibly afford additional information after all possible data from open-tube gastroscopy has been obtained. care must be exercised not to exert an injurious degree of air-pressure. the distended portion of the stomach assumes a funnel-like form ending at the apex in a depression with radiating folds, that leads the observer to think he is looking at the pylorus. the foreshortening produced by the lens system also contributes to this illusion. the best lens-system gastroscope is that of henry janeway, which combines the open-tube and the lens system. _gastroscopy for foreign bodies_.--the great majority of foreign bodies that reach the stomach unassisted are passed per rectum, provided the natural protective means are not impaired by the administration of cathartics, changes in diet, etcetera. this, however, does not mean that esophageal foreign bodies should be pushed into the stomach by blind methods, or by esophagoscopy, because a swallowed object lodged in the esophagus can always be returned through the mouth. foreign bodies in the stomach and intestines should be fluoroscopically watched each second day. if an object is seen to lodge five days in one location in the intestines, it should be removed by laparotomy, since it will almost certainly perforate. certain objects reaching the stomach may be judged too large to pass the pylorus and intestinal angles. these should be removed by gastroscopy when such decision is made. it is to be remembered that gastric foreign bodies may be regurgitated and may lodge in the esophagus, whence they are easily removed by esophagoscopy. the double-planed fluoroscope of manges is helpful in the removal of gastric foreign bodies, but there is great danger of injury to the stomach walls, and even the peritoneum, unless forceps are used with the utmost caution. [277] chapter xxxvi--acute stenosis of the larynx _etiology_.--causes of a relatively sudden narrowing of the lumen of the larynx and subjacent trachea are included in the following list. two or more may be combined. 1. foreign body. 2. accumulation of secretions or exudate in the lumen. 3. distension of the tissues by air, inflammatory products, serum, pus, etc. 4. displacement of relatively normal tissues, as in abductor paralysis, congenital laryngeal stridor, etcetera. 5. neoplasms. 6. granulomata. _edema of the larynx_ may be at the glottic level, or in the supraglottic or subglottic regions. the loose cellular tissue is most frequently concerned in the process rather than the mucosal layer alone. in children the subglottic area is very vascular, and swelling quickly results from trauma or inflammation, so that acute stenosis of the larynx in children commonly has its point of narrowing below the cords. dyspnea, and croupy, barking, cough with no change in the tone or pitch of the speaking voice are characteristic signs of subglottic stenosis. edema may accompany inflammation of either the superficial or deep structures of the larynx. the laryngeal lesion may be primary, or may complicate general diseases; among the latter, typhoid fever deserves especial mention. _acute laryngeal stenosis_ complicating typhoid fever is frequently overlooked and often fatal, for the asthenic patient makes no fight for air, and hoarseness, if present, is very slight. the laryngeal lesion may be due to cordal immobility from either paralysis or inflammatory arytenoid fixation, in the absence of edema. perichondritis and chondritis of the laryngeal cartilages often follow typhoid ulceration of the larynx, chronic stenosis resulting. _laryngeal stenosis in the newborn_ may be due to various anomalies of the larynx or trachea, or to traumatism of these structures during delivery. the normal glottis in the newborn is relatively narrow, so that even slight encroachment on its lumen produces a serious degree of dyspnea. the characteristic signs are inspiratory indrawing of the supraclavicular fossae, the suprasternal notch, the epigastrium, and the lower sternum and ribs. cyanosis is seen at first, later giving place to pallid asphyxia when cardiac failure occurs. little air is heard to enter the lungs, during respiratory efforts and the infant, becoming exhausted by the great muscular exertion, soon ceases to breathe. paralytic stenosis of the larynx sometimes follows difficult forceps deliveries during which stretching or compression of the recurrent nerves occur. _acute laryngeal stenosis in infants, from laryngeal perichondritis_, may be a delayed result of traumatism to the laryngeal cartilages during delivery. the symptoms usually develop within four weeks after birth. lues and tuberculosis are possible factors to be eliminated by the usual methods. _surgical treatment of acute laryngeal stenosis_.--multiple puncture of acute inflammatory edema, while readily performed with the laryngeal knife used through the direct laryngoscope, is an uncertain measure of relief. tracheotomy, if done low in the neck, will completely relieve the dyspnea. by its therapeutic effect of rest, it favors the rapid subsidence of the inflammation in the larynx and is the treatment to be preferred. intubation is treacherous and unreliable except in diphtheritic cases; but in the diphtheritic cases it is ideal, if constant skilled watching can be had. [279] chapter xxxvii--tracheotomy _indications_.--tracheotomy is indicated in dyspnea of laryngotracheal origin. the cardinal signs of this form of dyspnea are: 1. indrawing at the suprasternal notch. 2. indrawing around the clavicles. 3. indrawing of the intercostal spaces. 4. restlessness. 5. choking and waking as soon as the aid of the voluntary respiratory muscles ceases in falling to sleep. 6. cyanosis is a dangerously late symptom. as a therapeutic measure in diseases of the larynx its place has been thoroughly established. marked improvement of the laryngeal lesions has been observed to follow tracheotomy in advanced laryngeal tuberculosis, and in cancer of the larynx. it has proven, in some cases, a useful adjunct in the treatment of luetic laryngitis, though it cannot be regarded as indicated, in the absence of dyspnea. perichondritis and other inflammations are benefited by tracheotomy. a marked therapeutic effect on multiple laryngotracheal papillomata in children has been noted by the author in hundreds of cases. _tracheotomy for foreign body_ is no longer indicated either for the removal of the intruder, or for the insertion of the bronchoscope. tracheotomy may be urgently indicated for foreign body dyspnea, but not for foreign body removal. _subcutaneous rupture of the trachea_ from external trauma may produce dyspnea and generalized emphysema, both of which will be relieved by tracheotomy. [280] _acromegalic stenosis of the larynx_ is a rare but urgent indication for tracheotomy. _contraindications_.--there are no contraindications to tracheotomy for dyspnea. _the instruments_ required for an orderly tracheotomy are: headlight scalpels 2 retractors trousseau dilator 6 hemostats scissors (dissecting) tracheal cannulae (six sizes) curved needles needle holder hypodermic syringe for local anesthesia no. 1 plain catgut ligatures linen tape gauze sponges these are sterilized and kept in a sterile copper box ready for instant use. beside the patient's bed following the tracheotomy the following sterile materials are placed: sterile gloves 1 hemostat sterile new gauze trousseau dilator scissors duplicate tracheotomy tube silver probe basin of bichloride of mercury solution, 1 : 10,000 tracheotomy is one of the oldest operations known to surgery, yet strange to say, it is probably more often improperly performed today, and more often followed by needless mortality, than any other operation. the two chief preventable sequelae are death from improper routine surgical care and wrongly fitted tube, and stenosis from too high an operation. the classical descriptions of crico-thyroidotomy and high and low tracheotomy have been handed down to generations of medical students without revision. every medical graduate has been taught that there are two kinds of tracheotomy, high and low, the low operation being very difficult, the high operation very easy. when he is suddenly called upon to do an emergency tracheotomy, this erroneous teaching is about all that remains in the dim recesses of his memory; consequently he makes sure of doing the operation high enough, and goes in through the larynx, usually dividing the cricoid cartilage, the only complete ring in the trachea. as originally made the distinction between high and low as applied to tracheotomy referred to operations above and below the isthmus of the thyroid gland, in a day when primitive surgery attached too much importance to operations upon the thyroid gland. the isthmus is entitled to absolutely no consideration whatever in deciding the location at which to incise so vital a structure as the trachea. students are taught different short skin incisions for these two operations, and it is no wonder that they, as did their predecessors, find tracheotomy a difficult, bloody, and often futile operation. the trachea is searched for at the bottom of a short, deep wound filled with blood, the source of which is difficult to find and impossible to control. _tracheotomic cannulae_ should be made of sterling silver. german silver plated with pure silver is good enough for temporary use, but the plating soon wears off under the galvanic action set up between the two metals. aluminum becomes roughened by boiling and contact with secretions, and causes the formation of granulations which in time lead to stenosis. hard rubber tubes cannot be boiled, the walls are so thick as to leave too little lumen, and the rubber is irritating to the tissues. all tracheotomy tubes should be fitted with pilots. many of the tubes furnished to patients have no pilots to facilitate the introduction, and the tubes are inserted with somewhat the effect of a cheese tester, and with great pain and suffering on the part of the patient. most of the the tubes in the shops are too short to allow for the swelling of the tissues of the neck following the operation. they may reach the trachea at the time of the operation, but as soon as the reactionary swelling occurs, the end of the tube is pulled out (fig. 103) of the tracheal incision; the air hissing along the tube is considered by the attendant to indicate that the tube is still in place, and the increasing dyspnea and accelerated respiratory rate are attributed to supposed pneumonia or edema of the lungs, under which erroneous diagnosis the patient is buried. in all cases in which it is reported that in spite of tracheotomy the dyspnea was only temporarily relieved, the fault is the lack of a "plumber." that is, an attendant who will make sure that there is at all times a clear airway all the way down to the lungs. with a bronchoscope and aspirator he will see that the airway is clear. to begin with, a proper sized cannula must be selected. the series of different sized, full curved tubes, one of which is illustrated in fig. 104, will under all conditions reach the trachea. if the tube seems to be too long in any given case, it will usually be found that the tracheotomy has been done too high, and a lower one should be done at once. if the operation has not been done too high, and the cannula is too long, a pad of gauze under the shield will take up the surplus length. in cases of tracheal compression from new growth, thymus or other such cases, in which the ordinary tube will not pass the obstruction, the author's long cane-shaped cannula (see fig. 104) can be inserted past the obstruction, and if necessary into either bronchus. the fenestrum placed in the cannula in many of the older tubes, with the supposed function of allowing partial breathing through the larynx, is a most pernicious thing. a properly fitted tube should not take up more than half of the cross section of the trachea, and should allow the passage of sufficient air for free laryngeal breathing when it is completely corked. the fenestrum is, moreover, rarely so situated that air can pass through it; the fenestral edges act as a constant irritant to the wound, producing bleeding and granulation tissue. [fig. 103.--schema showing thick pad of gauze dressing, filling the space, a, and used to hold out the author's full-curved cannula when too long, prior to reactionary swelling, and after subsidence of the latter. at the right is shown the manner in which the ordinary cannula of the shops permits a patient to asphyxiate, though some air is heard passing through the tracheal opening, h, after the cannula has been partially withdrawn by swelling of the tissues, t.] [fig. 104.--the author's tracheotomic cannulae. a, shows cane-shaped cannula for use in intrathoracic compressive or other stenoses. b, shows full curved cannula for regular use. pilots are made to fit the outer cannula; the inner cannula not being inserted until after withdrawal of the pilot.] _anesthesia_.--no dyspneic patient should be given a general anesthetic; because any patient dyspneic enough to need a tracheotomy for dyspnea is depending largely upon the action of the accessory respiratory muscles. when this action is stopped by beginning unconsciousness, respiration ceases. if the trachea is not immediately opened, artificial respiration instituted, and oxygen insufflated, the patient dies on the table. skin infiltration along the line of incision with a very weak cocaine solution (1/10 of 1 per cent), apothesine (2 per cent), novocaine, schleich's fluid or other local anesthetic, suffices to render the operation painless. the deeper structures have little sensation and do not require infiltration. it has been advocated that an interannular injection of cocaine solution with a hypodermic syringe be done just prior to incision of the trachea for the purpose of preventing cough after the incision of the trachea and the insertion of the cannula. it would seem, however, that this introduces the risk of aspiration pneumonia and pulmonary abscess, by permitting the aspiration and clotting of blood in small bronchi, followed by subsequent breaking down of the clots. as the author has so often said, "the cough reflex is the watch dog of the lungs," and if not drugged asleep by local or general anesthesia can safely be relied upon to prevent all possibility of the blood or the pus which nearly always is present in acute or chronic conditions calling for tracheotomy, being aspirated into the deeper air-passages. cocaine in any form, by any method, and in any dosage, is dangerous in very young children. _technic_.--the patient should be placed in the recumbent position, with the extended head held in the midline by an assistant. the shoulders, not the neck, should be slightly raised with a sand bag. the head should be somewhat lower than the feet, to lessen the danger of aspiration of blood. a midline incision dividing the skin and fascia is made from the thyroid notch to just above the suprasternal notch. the cricoid is now located, and the deeper dissection is continued from below this point. the ribbon muscles are separated with dissecting scissors or knife, and held apart with retractors. if the isthmus of the thyroid gland is in the way, it may be retracted upward; if large, however, it should be divided and ligated, for it is apt to slip over the tracheal incision afterward, and render difficult the quick finding of the incision during after-care. this covering of the tracheal incision by the slipping back of the drawn-aside thyroidal isthmus is one of the most frequent avoidable causes of mortality, because it deflects the cannula off into the tissues when it is replaced after cleaning during the early postoperative period. the corrugated surface of the trachea can be felt, and its exact location can be determined by the index finger. if the tracheotomy is proceeding in an orderly manner, all bleeding points should be caught and tied with plain catgut (no. 1) before the trachea is opened. because of distension of vessels during cough, all but the tiniest vessels should be ligated. side-cut veins are particularly treacherous. they should be freed of tissue, cut across and the divided ends ligated. the _incision in the trachea_ should be as low as possible, and should never be made through the first ring. the incision should be through the third, fourth and fifth rings. only in cases of laryngoptosis will it be necessary to incise the trachea higher than this. the incision must be made in the midline, and in the long axis of the trachea, and care must be exercised that the point of the knife does not perforate the posterior tracheal wall. stab incisions are always to be avoided. if the incision in the trachea is found to be of insufficient length, the original incision must be found and elongated. a second incision must not be made, for the portion of cartilage between the two incisions will die and will almost certainly make a site of future tracheal stenosis. the cricoid should never be cut, for stenosis is almost sure to follow the wearing of a cannula in this position. a trousseau dilator should now be inserted in the tracheal incision, its blades gently separated. with the tracheal lumen thus opened, a cannula of proper size is introduced with absolute certainty of its having entered the trachea. a quadruple-folded square of gauze in the form of a pad about four inches square is moistened with mercuric chloride solution (1:10,000) and is slit from the lower border to its midpoint. this pad is slipped from above downward under the tape holder of the cannula, the slit permitting the tubal part of the cannula to reach the central part of the pad (fig. 108), and completely covers the wound. no attempt should be made to suture the skin wound, for this tends to form a pocket in which lodge the bronchial secretions that escape alongside the tube, resulting in infection of the wound. furthermore it renders the daily changing of the tube much more difficult. in fact it prevents the attendant from being certain that the tube is actually placed in the trachea. suturing of the skin to the trachea should never be done, for the sutures soon tear out and often set up a perichondritis of the tracheal cartilages, with resulting difficult decannulation. [fig. 105.--schema of practical gross anatomy to be memorized for emergency tracheotomy. the middle line is the safety line, the higher the wider. below, the safety line narrows to the vanishing point vp. the upper limit of the safety line is the thyroid notch until the trachea is bared, when the limit falls below the first tracheal ring. in practice the two-dark danger lines are pushed back with the left thumb and middle finger as shown in fig. 106, thus throwing the safety line into prominence. this is generally known as jackson's tracheotomic triangle.] [fig. 106.--schema showing the author's method of rapid tracheotomy. first stage. the hands are drawn ungloved for the sake of clearness. the upper hand is the left, of which the middle finger (m) and the thumb are used to repress the sterno-cleido-mastoid muscles, the finger and thumb being close to the trachea in order to press backward out of the way the carotid arteries and the jugular vein. this throws the trachea forward into prominence, and one deep slashing cut will incise all of the soft tissues down to the trachea.] _emergency tracheotomy_.--stabbing of the cricothyroid membrane, or an attempted stabbing of the trachea, so long taught as an emergency tracheotomy, is a mistake. the author's "two stage, finger guided" method is safer, quicker, more efficient, and not likely to be followed by stenosis. to execute this promptly, the operator is required to forget his textbook anatomy and memorize the schema (fig. 105). the larynx and trachea are steadied by the thumb and middle finger of the left hand, which at the same time push back the important nerves and vessels which parallel the trachea, and render the central safety line more prominent (fig. 106). a long incision is now made from the thyroid notch almost to the suprasternal notch, and deep enough to reach the trachea. this completes the first stage. [fig. 107.--illustrating the author's method of quick tracheotomy. second stage. the fingers are drawn ungloved for the sake of clearness. in operating the whole wound is full of blood, and the rings of the trachea are felt with the left index which is then moved slightly to the patient's left, while the knife is slid down along the left index to exactly the middle line when the trachea is incised.] second stage. the entire wound is full of blood and the trachea cannot be seen, but its corrugations can be very readily felt by the tip of the free left index finger. the left index finger is now moved a little to the patient's left in order that the knife shall come precisely in the midline of the trachea, and three rings of the trachea are divided from above downward (fig. 107). the trousseau dilator should now be inserted, the head of the table should be lowered, and the patient should be turned on the side to allow the blood to run away from the wound. if respiration has ceased, a cannula is slipped in, and artificial respiration is begun. oxygen insufflation will aid in the restoration of respiration, and a pearl of amyl nitrite should be crushed in gauze and blown in with the oxygen. in all such cases, excessive pressure of oxygen should be avoided because of the danger of producing ischemia of the lungs. hope of restoring respiration should not be abandoned for half an hour at least. one of the author's assistants, dr. phillip stout, saved a patient's life by keeping up artificial respiration for twenty minutes before the patient could do his own breathing. the _after-care_ of the tracheotomic wound is of the utmost importance. a special day and night nurse are required. the inner tube of the cannula must be removed and cleaned as soon as it contains secretion. secretion coughed out must be wiped away quickly, but gently, before it is again aspirated. the gauze dressing covering the wound must be changed as soon as soiled with secretions from the wound and the air-passages. each fresh pad should be moistened with very weak bichloride of mercury solution (1:10,000). the outer tube must be changed every twenty-four hours, and oftener if the bronchial secretion is abundant. student-physicians who have been taught my methods and who have seen the cases in care of our nurses have often expressed amazement at the neglect unknowingly inflicted on such cases elsewhere, in the course of ordinary routine surgery. it is not unusual for a patient to be sent to the bronchoscopic clinic who has worn his cannula without a single changing for one or two years. in some cases the tube had broken and a portion had been aspirated into the trachea. [fig. 108.--method of dressing a tracheotomic wound. a broad quadruple, in-folded pad of gauze is cut to its centre so that it can be slipped astride of the tube of the cannula back of the shield. no strings, ravellings or strips of gauze are permissible because of the risk of their getting down into the trachea.] if the respiratory rate increases, instead of attributing it to pulmonary complications, the entire cannula should be removed, the wound dilated with the trousseau forceps, the interior of the trachea inspected, and all secretions cleaned away. then the tracheal mucosa below the wound should be gently touched with a sterile bent probe, to induce cough to rid the lower air passages of accumulated secretions. in many cases it is a life-saving procedure to insert a sterile long malleable aspirating tube to remove secretions from the lower air-passages. when all is clear, a fresh sterile cannula which has been carefully inspected to see that its lumen has been thoroughly cleaned, is inserted, and its tapes tied. good "plumbing," that is, the maintenance at all times of a clear, clean passage in all the "pipes," natural and artificial, is the reason why the mortality in the bronchoscopic clinic has been less than half of one per cent, while in ordinary routine surgical care in all hospitals collectively it ranges from 10 to 20 per cent. _bronchial aspiration_.--as mentioned above, bronchial aspiration is often necessary. when the patient is unable to get up secretions, he will, as demonstrated by the author many years ago, "drown in his own secretions." in some cases bronchoscopic aspiration is required (peroral endoscopy, p. 483). occasionally, very thick secretions will require removal with forceps. pus may become very thick and gummy from the administration of morphin. opiates do not lessen pus formation, but they do lessen the normal secretions that ordinarily increase the quantity and fluidity of the pus. when to this is added the dessicating effect of the air inhaled through the cannula, unmoistened by the upper air-passages, the secretions may be so thick as to form crusts and plugs that are equivalent to foreign bodies and require removal with forceps. diphtheritic membrane in the trachea may require removal with bronchoscope and forceps. thinner secretions may be removed by sponge-pumping. in most cases, however, secretions can be brought up through an aspirating tube, connected to a bronchoscopic aspirating syringe (fig. 11), an ordinary aspirating bottle, or preferably, a mechanical aspirator such as that shown in fig. 12. in this, combined with bronchoscopic oxygen insuflation (q.v.), we have a life-saving measure of the highest efficiency in cases of poisoning by chlorine and other irritant and asphyxiating gases. an aspirating tube for insertion into the deeper air passages should be of copper, so that it can be bent to the proper curve to reach into the various parts of the tracheobronchial tree, and it should have a removable copper-wire core to prevent kinking, and collapse of the lumen. the distal end should be thickened, and also perforated at the sides, to prevent drawing-in of the mucosa and trauma thereto. a rubber tube may be used, but is not so satisfactory. the one shown in fig. 10 i had made by mr. pilling, and it has proved very satisfactory. _decannulation_.--when the tracheal incision is placed below the first ring, no difficulty in decannulation should result from the operation per se. when by temporarily occluding the cannula with the finger it is evident that the laryngeal aperture has regained sufficient size to allow free breathing, a smaller-sized tracheotomic tube should be substituted to allow free passage of air around the cannula in the trachea. in doing this, the amount of secretion and the handicap of impaired glottic mobility in the expulsion of thick secretions must be borne in mind. babies labor under a special handicap in their inefficient bechic expulsion and especially in their small cannulae which are so readily occluded. if breathing is not free and quiet with the smaller tube; the larger one must be replaced. if, however, there is no trouble with secretions, and the breathing is free and quiet, the inner cannula should be removed, and the external orifice of the outer cannula firmly closed with a rubber cork. if the laryngeal condition has been acute, decannulation can usually be safely done after the patient has been able to sleep quietly for three nights with a corked cannula. if free breathing cannot be obtained when the cannula is corked, the larynx is stenosed, and special work will be required to remove the tube. children sometimes become panic stricken when the cannula is completely corked at once and they are forced to breathe through the larynx instead of the easier shortcut through the neck. in such a case, the first step is partially to cork the cannula with a half or two-thirds plug made from a pure rubber cord fashioned in the desired shape by grinding with an emery wheel (fig. 112). thus the patient is gradually taught to use the natural air-way, still feeling that he has an "anchor to windward" in the opening in the cannula. when some swelling of the laryngeal structures still exists, this gradual corking has a therapeutic effect in lessening the stenosis by exercising the muscles of abduction of the cords and mobilizing the cricoarytenoid articulation during the inspiratory effort. the forced respiration keeps the larynx freed from secretions, which are more or less purulent and hence irritating. after removing the cannula, in order that healing may proceed from the bottom upward, the wound should be dressed in the following manner: a single thickness of gauze should be placed over the wound and the front of the neck, and a gauze wedge firmly inserted over this to the depths of the tracheotomic wound, all of this dressing being held in place by a bandage. if the skin-wound heals before the fibrous union of the tracheal cartilages is complete, exuberant granulations are apt to form and occlude the trachea, perhaps necessitating a new tracheotomy for dyspnea. it is so important to fix indelibly in the mind the cardinal points concerning tracheotomy that i have appended to this chapter the teaching notes that i have been for years giving my classes of students and practitioners, hundreds of whom have thanked me for giving them the clear-cut conception of tracheotomy that enabled them, when their turn came to do an emergency tracheotomy, to save human life. resume of tracheotomy _instruments_. headlight sandbag scalpel hemostats small retractors tenaculum tracheotomic cannulae (proper kind) long. half area cross-section trachea. proper curve: radius too short will press ant. tracheal wall;

(b) the cannula is long enough to reach well down into the trachea. a cannula that was long enough when the operation was done may be too short after the cervical tissues swell. (c) the distal end of the cannula actually is deeply in the trachea. the only way to be sure is, when inserting the cannula, to spread the wound and the tracheal incision with a trousseau dilator, then _see_ the interior of the tracheal lumen and _see_ the cannula enter therein. 15. if after attending to the above mentioned details there are still signs of obstructive dyspnea, a bronchoscopy should be done for finding and removal of the obstruction in the trachea or main bronchi. 16. if all the "pipes," natural and instrumental, are clear there can be no such thing as obstructive dyspnea. 17. pneumonia and pulmonary edema may exist before tracheotomy, but they are rare sequelae. 18. decannulation, in cases of tracheotomy done for temporary conditions should not be attempted until the patient has slept at least 3 nights with his cannula tightly corked. a properly fitted cannula (i.e. one not larger than half the area of cross section of the trachea) permits the by-passage of plenty of air. a partial cork should be worn for a few days first for testing and "weaning" a child away from the easier breathing through the neck. in cases of chronic laryngeal stenosis a prolonged test is necessary before attempting decannulation. 19. a tracheotomic case may be aphonic, hence unable to call for help. 20. the foregoing rules apply to the post-operative periods. after the wound has healed and a fistula is established, the patient, if not a child, may learn to care for his own cannula. [298] 21. do not give cough-sedatives or narcotics. the cough reflex is the watch dog of the lungs. notes on nursing tracheotomized patients bedside tray should contain: duplicate cannula scalpel trousseau dilator hemostat dressing forceps sterile vaseline scissors tape probe gauze sponges gauze squares probe-pointed curved bistoury. 1. room should be abundantly ventilated, as free from dust and lint as possible, and the air should be moistened by steam in winter. 2. keep mouth clean. tooth brush. rinse alcohol 1:10. 3. sponge away secretion after the cough before drawn in. 4. remove inner cannula (not outer) as often as needed. not less often than every hour. replace immediately. never boil a cannula until you have thoroughly cleaned it. 5. obstruction of cannula calling for cleaning indicated by: blue or ashy color. indrawing at clavicles, sternal notch, epigastrium. noisy breathing.

[299] 12. report at once if food or water leaks through wound. (coughing and choking). 13. never leave a tracheotomized patient unwatched during the first days or weeks, according to case. 14. remember trousseau dilator or hemostat will spread the tracheal wound or fistula when cannula is out. 15. remember life depends on a clear cannula if the patient gets no air through the mouth. 16. remember it takes very little to clog the small cannula of a child. 17. remember a tracheotomized patient cannot call for help. 18. decannulation. testing by corking partially. watch corks not too small, or broken. attach them by braided silk thread. pure rubber cord ground down makes best cork. [300] chapter xxxviii--chronic stenosis of the larynx and trachea the various forms of laryngeal stenosis for which tracheotomy or intubation has been performed, and the difficulties encountered in restoring the natural breathing, may be classified into the following types: 1. panic 2. spasmodic 3. paralytic 4. ankylotic (arytenoid) 5. neoplastic 6. hyperplastic 7. cicatricial (a) loss of cartilage (b) loss of muscular tissue (c) fibrous _panic_.--nothing so terrifies a child as severe dyspnea; and the memory of previous struggles for air, together with the greater ease of breathing through the tracheotomic cannula than through even a normal larynx, incites in some cases so great a degree of fear that it may properly be called panic, when attempts at decannulation are made. crying and possibly glottic spasm increase the difficulties. _spasmodic stenosis_ may be associated with panic, or may be excited by subglottic inflammation. prolonged wearing of an intubation tube, by disturbing the normal reciprocal equilibrium of the abductors and adductors, is one of the chief causes. the treatment for spasmodic stenosis and panic is similar. the use of a special intubation tube having a long antero-posterior lumen and a narrow neck, which form allows greater action of the musculature, has been successful in some cases. repeated removal and replacement of the intubation tube when dyspnea requires it may prove sufficient in the milder cases. very rarely a tracheotomy may be required; if so, it should be done low. the wearing of a tracheotomic cannula permits a restoration of the muscle balance and a subsidence of the subglottic inflammation. corking the cannula with a slotted cork (fig. 111) will now restore laryngeal breathing, after which the tracheotomic cannula may be removed.

in most cases, however, operation on both sides is needed. an interval of two months between operations is advisable to avoid adhesions. in almost all cases, ventriculocordectomy will result in a sufficient increase in the glottic chink for normal respiration. the ultimate vocal results are good. evisceration of the larynx, either by the endoscopic or thyrotomic method, usually yields excellent results when no lesion other than paralysis exists. only too often, however, the condition is complicated by the results of a faultily high tracheotomy. a rough, inflexible voice is ultimately obtained after this operation, especially if the arytenoid cartilage is unharmed. in recent bilateral recurrent paralysis, it may be worthy of trial to suture the recurrent to the pneumogastric. operations on the larynx for paralytic stenosis should not be undertaken earlier than twelve months from the inception of the condition, this time being allowed for possible nerve regeneration, the patient being made safe and comfortable, meanwhile, by a low tracheotomy. _ankylosis_.--fixation of the crico-arytenoid joints with an approximation of the cords may require evisceration of the larynx. this, however, should not be attempted until after a year's lapse, and should be preceded by attempts to improve the condition by endoscopic bouginage, and by partial corking of the tracheotomic cannula. _neoplasms_.--decannulation in neoplastic cases depends upon the nature of the growth, and its curability. cicatricial contraction following operative removal of malignant growths is best treated by intubational dilatation, provided recurrence has been ruled out. the stenosis produced by benign tumors is usually relieved by their removal. _papillomata_.--decannulation after tracheotomy done for papillomata should be deferred at least 6 months after the discontinuance of recurrence. not uncommonly the operative treatment of the growths has been so mistakenly radical as to result in cicatricial or ankylotic stenoses which require their appropriate treatments. it is the author's opinion that recurrent papillomata constitute a benign self-limited disease and are best treated by repeated superficial removals, leaving the underlying normal structures uninjured. this method will yield ultimately a perfect voice and will avoid the unfortunate complications of cicatricial hypertrophic and ankylotic stenosis. _compression stenosis of the trachea_.--decannulation in these cases can only follow the removal of the compressive mass, which may be thymic, neoplastic, hypertrophic or inflammatory. glandular disease may be of the hodgkins' type. thymic compression yields readily to radium and the roentgenray, and the tuberculous and leukemic adenitides are sometimes favorably influenced by the same agents. surgery will relieve the compression of struma and benign neoplasms, and may be indicated in certain neoplasms of malignant origin. the possible coexistence of laryngeal paralysis with tracheal compression is frequently overlooked by the surgeon. monolateral or bilateral paralysis of the larynx is by no means an uncommon postoperative sequel to thyroidectomy, even though the recurrent nerves have been in no way injured at operation. probably a localized neuritis, a cicatricial traction, or inclusion of a nerve trunk accounts for most of these cases. _hyperplastic and cicatricial chronic stenoses_ preventing decannulation may be classified etiologically as follows: 1. tuberculosis 2. lues 3. scleroma 4. acute infectious diseases (a) diphtheria (b) typhoid fever (c) scarlet fever (d) measles (e) pertussis 5. decubitus (a) cannular (b) tubal 6. trauma (a) tracheotomic (b) intubational (c) operative (d) suicidal and homicidal (e) accidental (by foreign bodies, external violence, bullets, etc.) most of the organic stenoses, other than the paralytic and neoplastic forms, are the result of inflammation, often with ulceration and secondary changes in the cartilages or the soft tissues. [304] _tuberculosis_.--in the non-cicatricial forms, galvanocaustic puncture applied through the direct laryngoscope will usually reduce the infiltrations sufficiently to provide a free airway. should the pulmonary and laryngeal tuberculosis be fortunately cured, leaving, however, a cicatricial stenosis of the larynx, decannulation may be accomplished by laryngostomy. _lues_.--active and persistent antiluetic medication must precede and accompany any local treatment of luetic laryngeal stenosis. prolonged stretching with oversized intubation tubes following excision or cauterization may sometimes be successful, but laryngostomy is usually required to combat the vicious contraction of luetic cicatrices. _scleroma_ is rarely encountered in america. radiotherapy has been advocated and good results have been reported from the intravenous injection of salvarsan. radium may be tried, and its application is readily made through the direct laryngoscope. _diphtheria_.--chronic postdiphtheritic stenosis may be of the panic, spasmodic or, rarely, the paralytic types; but more often it is of either the hypertrophic or cicatricial forms. only too frequently the stenosis should be called posttracheotomic rather than postdiphtheritic, since decannulation after the subsidence of the acute stenosis would have been easy had it not been for the sequelae of the faulty tracheotomy. prolonged intubation may induce either a supraglottic or subglottic tissue hyperplasia. _the supraglottic type_ consists in an edematous thickening around the base of the epiglottis, sometimes involving also the glossoepiglottic folds and the ventricular bands. an improperly shaped or fitted tube is the usual cause of this condition, and a change to a correct form of intubation tube may be all that is required. excessive polypoid tissue hypertrophy should be excised. the less redundant cases subside under galvanocaustic treatment, which may be preceded by tracheotomy and extubation, or the intubation tube may be replaced after the application of the cautery. the former method is preferable since the patient is far safer with a tracheotomic cannula and, further, the constant irritation of the intubation tube is avoided. _subglottic hypertrophic stenosis_ consists in symmetrical turbinal-like swellings encroaching on the lumen from either side. cautious galvanocauterant treatment accurately applied by the direct method will practically always cure this condition. preliminary tracheotomy is required in those cases in which it has not already been done, and in the cases in which a high tracheotomy has been done, a low tracheotomy must be the first step in the cure. cicatricial types of postdiphtheritic stenosis may be seen as webs, annular cicatrices of funnel shape, or masses of fibrous tissue causing fixation of the arytenoids as well as encroachment on the glottic lumen. (see color plates.) as a rule, when a convalescent diphtheritic patient cannot be extubated two weeks after three negative cultures have been obtained the advisability of a low tracheotomy should be considered. if a convalescent intubated patient cough up a tube and become dyspneic a low tracheotomy is usually preferable to forcing in an oversized intubation tube. _typhoid fever_.--ulcerative lesions in the larynx during typhoid fever are almost always the result of mixed infection, though thrombosis of a small vessel, with subsequent necrosis is also seen. if the ulceration reaches the cartilage, cicatricial stenosis is almost certain to follow. _trauma_.--the chief traumatic factors in chronic laryngeal stenosis are: (a) prolonged presence of a foreign body in the larynx (b) unskilled attempts at intubation and the wearing of poorly fitting intubation tubes; (c) a faulty tracheotomy; (d) a badly fitting cannula; (e) war injuries; (f) attempted suicide; (g) attempted homicide; (h) neglect of cleanliness and care of either intubation tubes or tracheotomic cannulae allowing incrustation and roughening which traumatize the tissues at each movement of the ever-moving larynx and trachea. _treatment of cicatricial stenosis_.--a careful direct endoscopic examination is essential before deciding on the method of treatment for each particular case. granulations should be removed. intubated cases are usually best treated by tracheotomy and extubation before further endoscopic treatment is undertaken. a certain diagnosis as to the cause of the condition must be made by laboratory and therapeutic tests, supplemented by biopsy if necessary. vigorous antiluetic treatment, especially with protiodide of mercury, must precede operation in all luetic cases. necrotic cartilage is best treated by laryngostomy. intubational dilatation will succeed in some cases. [fig. 109.--schema showing the author's method of laryngostomy. the hollow upward metallic branch (n) of the cannula (c) holds the rubber tube (r) back firmly against the spur usually found on the back wall of the trachea. moreover, the air passing up through the rubber tube (r) permits the patient to talk in a loud whisper, the external orifice of the cannula being occluded most of the time with the cork (k). the rubber tubing, when large sizes are reached may extend down to the lower end of the cannula, the part c coming out through a large hole cut in the tubing at the proper distance from the lower end.] _laryngoscopic bouginage_ once weekly with the laryngeal bougies (fig. 42) will cure most cases of laryngeal stenosis. for the trachea, round, silk-woven, or metallic bougies (fig. 40) are better. [307] _laryngostomy_ consists in a midline division of the laryngeal and tracheal cartilages as low as the tracheotomic fistula, excision of thick cicatricial tissue, very cautious incision of the scar tissue on the posterior wall, if necessary, and the placing of the author's laryngostomy tube for dilatation (fig. 109). over the upward branch of the laryngostomy tube is slipped a piece of rubber tubing which is in turn anchored to the tape carrier by braided silk thread. progressively larger sizes of rubber tubing are used as the laryngeal lumen increases in size under the absorptive influence of the continuous elastic pressure of the rubber. several months of wearing the tube are required until dilatation and epithelialization of the open trough thus formed are completed. painstaking after-care is essential to success. when dilatation and healing have taken place, the laryngostomy wound in the neck is closed by a plastic operation to convert the trough into a trachea by supplying an anterior wall. _intubational treatment of chronic laryngeal stenosis_ may be tried in certain forms of stenosis in which the cicatrices do not seem very thick. the tube is a silver-plated brass one of large size (fig. 110). a post which screws into the anterior surface of the tube prevents its expulsion. over the post is slipped a block which serves to keep open the tracheal fistula. detailed discussion of these operative treatments is outside the scope of this work, but mention is made for the sake of completeness. before undertaking any of the foregoing procedures, a careful study of the complete descriptions in peroral endoscopy is necessary, and a practical course of training is advisable. [fig. 110.--the author's retaining intubation tube for treatment of chronic laryngeal stenosis. the tube (a) is introduced through the mouth, then the post (b) is screwed in through the tracheal wound. then the block (c) is slid into the wound, the square hole in the block guarding the post against all possibility of unscrewing. if the threads of the post are properly fitted and tightly screwed up with a hemostat, however, there is no chance of unscrewing and gauze packing is used instead of the block to maintain a large fistula. the shape of the intubation tube has been arrived at after long clinical study and trials, and cannot be altered without risk of falling into errors that have been made and eliminated in the development of this shape.] [309] chapter xxxix--decannulation after cure of laryngeal stenosis in order to train the patient to breathe again through the larynx it is necessary to occlude the cannula. this is best done by inserting a rubber cork in the inner cannula. at first it may be necessary to make a slot in the cork so as to permit some air to enter through the tube to supplement the insufficient supply obtainable through the insufficiently patulous glottis, new corks with smaller grooves being substituted as laryngeal breathing becomes easier. corking the cannula is an excellent orthopedic treatment in certain cases where muscle atrophy and partial inflammatory fixation of the cricoarytenoid joints are etiological factors in the stenosis. the added pull of the posterior cricoarytenoid muscles during the slight effort at inspiration restores their tone and increases the mobility of all the attached structures. by no other method can panic and spasmodic stenosis be so efficiently cured. [fig. 111.--illustration of corks used to occlude the cannula in training patients to breathe through the mouth again, before decannulation. the corks allow air leakage, the amount of which is regulated by the use of different shapes. a smaller and still smaller air leak is permitted until finally an ungrooved cork is tolerated. a central hole is sometimes used instead of a slot. a, one-third cork; b, half cork; c, three-quarter cork; d, whole cork.] following the subsidence of an acute laryngeal stenosis, it is my rule to decannulate after the patient has been able to breathe through the larynx with the cannula tightly corked for 3 days and nights. this rule does not apply to chronic laryngeal stenosis, for while the lumen under ordinary conditions might be ample, a slight degree of inflammation might render it dangerously small. in these cases, many weeks are sometimes required to determine when decannulation is safe. a test period of a few months is advisable in most cases of chronic laryngeal stenosis. recurrent contractions after closure of the wound are best treated by endoscopic bouginage. the corks are best made of pure rubber cord, cut and ground to shape, and grooved, if desired, on a small emery wheel (fig. 112). the ordinary rubber corks and those made of cork-bark should not be used because of their friability, and the possible aspiration of a fragment into the bronchus, where rubber particles form very irritant foreign bodies. [fig. 112.--this illustration shows the method of making safe corks for tracheotomic cannulae by grinding pure rubber cord to shape on an emery wheel. after grinding the taper, if a partial cork is desired, a groove is ground on the angle of the wheel. if a half-cork is desired half of the cork is ground away on the side of the wheel. reliable corks made in this way are now obtainable from messers charles j. pilling and son.] bibliography the following list of publications of the author may be useful for reference: 1. peroral endoscopy and laryngeal surgery, textbook, 1914.

the various articles contributed by the author to pepper's system of medicine, buck's reference handbook of the medical sciences, and keating's cyclopædia of the diseases of children. moreover, in the endeavor to present the subject as tersely and briefly as compatible with clear understanding, the several standard treatises on diseases of the skin by tilbury fox, duhring, hyde, robinson, anderson, and crocker, have been freely consulted, that of the last-named author suggesting the pictorial presentation of the "anatomy of the skin." the space allotted to each disease has been based upon relative importance. as to treatment, the best and approved methods only--those which are founded upon the aggregate experience of dermatologists--are referred to. for general information a

(_after duhring._)] #symptomatology.# the symptoms of cutaneous disease may be objective, subjective or both; and in some diseases, also, there may be systemic disturbance. #what do you mean by objective symptoms?# those symptoms visible to the eye or touch. #what do you understand by subjective symptoms?# those which relate to sensation, such as itching, tingling, burning, pain, tenderness, heat, anæsthesia, and hyperæsthesia. #what do you mean by systemic symptoms?# those general symptoms, slight or profound, which are sometimes associated, primarily or secondarily, with the cutaneous disease, as, for example, the systemic disturbance in leprosy, pemphigus, and purpura hemorrhagica. #into what two classes of lesions are the objective symptoms commonly divided?# primary (or elementary), and secondary (or consecutive). #primary lesions.# #what are primary lesions?# those objective lesions with which cutaneous diseases begin. they may continue as such or may undergo modification, passing into the secondary or consecutive lesions. #enumerate the primary lesions.# macules, papules, tubercles, wheals, tumors, vesicles, blebs and pustules. #what are macules (maculæ)?# variously-sized, shaped and tinted spots and discolorations, without elevation or depression; as, for example, freckles, spots of purpura, macules of cutaneous syphilis. #what are papules (papulæ)?# small, circumscribed, solid elevations, rarely exceeding the size of a split-pea, and usually superficially seated; as, for example, the papules of eczema, of acne, and of cutaneous syphilis. #what are tubercles (tubercula)?# circumscribed, solid elevations, commonly pea-sized and usually deep-seated; as, for example, the tubercles of syphilis, of leprosy, and of lupus. #what are wheals (pomphi)?# variously-sized and shaped, whitish, pinkish or reddish elevations, of an evanescent character; as, for example, the lesions of urticaria, the lesions produced by the bite of a mosquito or by the sting of a nettle. #what are tumors (tumores)?# soft or firm elevations, usually large and prominent, and having their seat in the corium and subcutaneous tissue; as, for example, sebaceous tumors, gummata, and the lesions of fibroma. #what are vesicles (vesiculæ)?# pin-head to pea-sized, circumscribed epidermal elevations, containing serous fluid; as, for example, the so-called fever-blisters, the lesions of herpes zoster, and of vesicular eczema. #what are blebs (bullæ)?# rounded or irregularly-shaped, pea to egg-sized epidermic elevations, with fluid contents; in short, they are essentially the same as vesicles and pustules except as to size; as, for example, the blebs of pemphigus, rhus poisoning, and syphilis. #what are pustules (pustulæ)?# circumscribed epidermic elevations containing pus; as, for example, the pustules of acne, of impetigo, and of sycosis. #secondary lesions.# #what are secondary lesions?# those lesions resulting from accidental or natural change, modification or termination of the primary lesions. #enumerate the secondary lesions.# scales, crusts, excoriations, fissures, ulcers, scars and stains. #what are scales (squamæ)?# dry, laminated, epidermal exfoliations; as, for example, the scales of psoriasis, ichthyosis, and eczema. #what are crusts (crustæ)?# dried effete masses of exudation; as, for example, the crusts of impetigo, of eczema, and of the pustular and ulcerating syphilodermata. #what are excoriations (excoriationes)?# superficial, usually epidermal, linear or punctate loss of tissue; as, for example, ordinary scratch-marks. #what are fissures (rhagades)?# linear cracks or wounds, involving the epidermis, or epidermis and corium; as, for example, the cracks which often occur in eczema when seated about the joints, the cracks of chapped lips and hands. #what are ulcers (ulcera)?# rounded or irregularly-shaped and sized loss of skin and subcutaneous tissue resulting from disease; as, for example, the ulcers of syphilis and of cancer. #what are scars (cicatrices)?# connective-tissue new formations replacing loss of substance. #what are stains?# discolorations left by cutaneous disease, which stains may be transitory or permanent. #distribution and configuration.# #what do you mean by a patch of eruption?# a single group or aggregation of lesions or an area of disease. #when is an eruption said to be limited or localized?# when it is confined to one part or region. #when is an eruption said to be general or generalized?# when it is scattered, uniformly or irregularly, over the entire surface. #when is an eruption universal?# when the whole integument is involved, without any intervening healthy skin. #when is an eruption said to be discrete?# when the lesions constituting the eruption are isolated, having more or less intervening normal skin. #when is an eruption confluent?# when the lesions constituting the eruption are so closely crowded that a solid sheet results. #when is an eruption uniform?# when the lesions constituting the eruption are all of one type or character. #when is an eruption multiform?# when the lesions constituting the eruption are of two or more types or characters. #when are lesions said to be aggregated?# when they tend to form groups or closely-crowded patches. #when are lesions disseminated?# when they are irregularly scattered, with no tendency to form groups or patches. #when is a patch of eruption said to be circinate?# when it presents a rounded form, and usually tending to clear in the centre; as, for example, a patch of ringworm. #when is a patch of eruption said to be annular?# when it is ring-shaped, the central portion being clear; as, for example, in erythema annulare. #what meaning is conveyed by the term "iris"?# the patch of eruption is made up of several concentric rings. difference of duration of the individual rings, usually slight, tends to give the patch variegated coloration; as, for example, in erythema iris and herpes iris. #what meaning is conveyed by the term "marginate"?# the sheet of eruption is sharply defined against the healthy skin; as, for example, in erythema marginatum, eczema marginatum. #what meaning is conveyed by the qualifying term "circumscribed"?# the term is applied to small, usually more or less rounded, patches, when sharply defined; as, for example, the typical patches of psoriasis. #when is the qualifying term "gyrate" employed?# when the patches arrange themselves in an irregular winding or festoon-like manner; as, for instance, in some cases of psoriasis. it results, usually, from the coalescence of several rings, the eruption disappearing at the points of contact. #when is an eruption said to be serpiginous?# when the eruption spreads at the border, clearing up at the older part; as, for instance, in the serpiginous syphiloderm. #relative frequency.# #name the more common cutaneous diseases and state approximately their frequency.# eczema, 30.4%; syphilis cutanea, 11.2%; acne, 7.3%; pediculosis, 4%; psoriasis, 3.3%; ringworm, 3.2%; dermatitis, 2.6%; scabies, 2.6%; urticaria, 2.5%; pruritus, 2.1%; seborrh[oe]a, 2.1%; herpes simplex, 1.7%; favus, 1.7%; impetigo, 1.4%; herpes zoster, 1.2%; verruca, 1.1%; tinea versicolor, 1%. total: eighteen diseases, representing 81 per cent. of all cases met with. (these percentages are based upon statistics, public and private, of the american dermatological association, covering a period of ten years. in private practice the proportion of cases of pediculosis, scabies, favus, and impetigo is much smaller, while acne, acne rosacea, seborrh[oe]a, epithelioma, and lupus are relatively more frequent.) #contagiousness.# #name the more actively contagious skin diseases.# impetigo contagiosa, ringworm, favus, scabies and pediculosis; excluding the exanthemata, erysipelas, syphilis and certain rare and doubtful diseases. [at the present time when most diseases are presumed to be due to bacteria or parasites the belief in contagiousness, under certain conditions, has considerably broadened.] #rapidity of cure.# #is the rapid cure of a skin disease fraught with any danger to the patient?# no. it was formerly so considered, especially by the public and general profession, and the impression still holds to some extent, but it is not in accord with dermatological experience. #ointment bases.# #name the several fats in common use for ointment bases.# lard, petrolatum (or cosmoline or vaseline), cold cream and lanolin. #state the relative advantages of these several bases.# _lard_ is the best all-around base, possessing penetrating properties scarcely exceeded by any other fat. _petrolatum_ is also valuable, having little, if any, tendency to change; it is useful as a protective, but is lacking in its power of penetration. _cold cream_ (ungt. aquæ rosæ) is soothing and cooling, and may often be used when other fatty applications disagree. _lanolin_ is said to surpass in its power of penetration all other bases, but this is not borne out by experience. it is an unsatisfactory base when used alone. it should be mixed with another base in about the proportion of 25% to 50%. these several bases may, and often with advantage, be variously combined. #what is to be added to these several bases if a stiffer ointment is required?# simple cerate, wax, spermaceti, or suet; or in some instances, a pulverulent substance, such as starch, boric acid, and zinc oxide. #class i.--disorders of the glands.# #hyperidrosis.# [illustration: fig. 6. a normal sweat-gland, highly magnified. (_after neumann._) _a_, sweat-coil: _b_, sweat-duct; _c_, lumen of duct; _d_, connective-tissue capsule; _e_ and _f_, arterial trunk and capillaries.] #what is hyperidrosis?# hyperidrosis is a functional disturbance of the sweat-glands, characterized by an increased production of sweat. this increase may be slight or excessive, local or general. #as a local affection, what parts are most commonly involved?# the hands, feet, especially the palmar and plantar surfaces, the axillæ and the genitalia. #describe the symptoms of the local forms of hyperidrosis.# the essential, and frequently the sole symptom, is more or less profuse sweating. if the hands are the parts involved, they are noted to be wet, clammy and sometimes cold. if involving the soles, the skin often becomes more or less macerated and sodden in appearance, and as a result of this maceration and continued irritation they may become inflamed, especially about the borders of the affected parts, and present a pinkish or pinkish-red color, having a violaceous tinge. the sweat undergoes change and becomes offensive. #is hyperidrosis acute or chronic?# usually chronic, although it may also occur as an acute affection. #what is the etiology of hyperidrosis?# debility is commonly the cause in general hyperidrosis; the local forms are probably neurotic in origin. #what is the prognosis?# the disease is usually persistent and often rebellious to treatment; in many instances a permanent cure is possible, in others palliation. relapses are not uncommon. #what systemic remedies are employed in hyperidrosis?# ergot, belladonna, gallic acid, mineral acids, and tonics. constitutional treatment is rarely of benefit in the local forms of hyperidrosis, and external applications are seldom of service in general hyperidrosis. precipitated sulphur, a teaspoonful twice daily, is also well spoken of, combined, if necessary, with an astringent. #what external remedies are employed in the local forms?# astringent lotions of zinc sulphate, tannin and alum, applied several times daily, with or without the supplementary use of dusting-powders. weak solutions of formaldehyde, one to one hundred, are sometimes of value. dusting-powders of boric acid and zinc oxide, to which may be added from ten to thirty grains of salicylic acid to the ounce, to be used freely and often:- [rx] pulv. ac. salicylici ................. gr. x-xxx. pulv. ac. borici ..................... [dram]v. pulv. zinci oxidi .................... [dram]iij m. diachylon ointment, and an ointment containing a drachm of tannin to the ounce; more especially applicable in hyperidrosis of the feet. the parts are first thoroughly washed, rubbed dry with towels and dusting-powder, and the ointment applied on strips of muslin or lint and bound on; the dressing is renewed twice daily, the parts each time being rubbed dry with soft towels and dusting-powder, and the treatment continued for ten days to two weeks, after which the dusting-powder is to be used alone for several weeks. no water is to be used after the first washing until the ointment is discontinued. one such course will occasionally suffice, but not infrequently a repetition is necessary. faradization and galvanization are sometimes serviceable. repeated mild exposures to the röntgen rays have a favorable influence in some instances. #sudamen.# (_synonym:_ miliaria crystallina.) #what is sudamen?# sudamen is a non-inflammatory disorder of the sweat-glands, characterized by pin-point to pin-head-sized, discrete but thickly-set, superficial, translucent whitish vesicles. #describe the clinical characters.# the lesions develop rapidly and in great numbers, either irregularly or in crops, and are usually to be seen as discrete, closely-crowded, whitish, or pearl-colored minute elevations, occurring most abundantly upon the trunk. in appearance they resemble minute dew-drops. they are non-inflammatory, without areola, never become purulent, and evince no tendency to rupture, the fluid disappearing by absorption, and the epidermal covering by desquamation. #give the course and duration of sudamen.# new crops may appear as the older lesions are disappearing, and the affection persist for some time, or, on the other hand, the whole process may come to an end in several days or a week. in short, the course and duration depend upon the subsidence or persistence of the cause. #what is the anatomical seat of sudamen?# the lesions are formed between the lamellæ of the corneous layer, usually the upper part; and are thought to be due to some change in the character of the epithelial cells of this layer, probably from high temperature, giving rise to a blocking up of the surface outlet. #what is the cause of sudamen?# debility, especially when associated with high fever. the eruption is often seen in the course of typhus, typhoid and rheumatic fevers. #how would you treat sudamen?# by constitutional remedies directed against the predisposing factor or factors, and the application of cooling lotions of vinegar or alcohol and water, or dusting-powders of starch and lycopodium. #hydrocystoma.# #describe hydrocystoma.# hydrocystoma is a cystic affection of the sweat-gland ducts, seated upon the face. the lesions may be present in scant numbers or in more or less profusion. they have the appearance of boiled sago grains imbedded in the skin; the larger lesions may have a bluish color, especially about the periphery. it is not common, and is usually seen in washerwomen and laundresses, or those exposed to moist heat. in some cases it tends to disappear during the winter months. there are no subjective symptoms. treatment consists of puncturing the lesions and application of dusting-powder. avoidance of the exciting cause (moist heat) is important. #anidrosis.# #describe anidrosis.# it is the opposite condition of hyperidrosis, and is characterized by diminution or suppression of the sweat secretion. it occurs to some extent in certain systemic diseases and also in some affections of the skin, such as ichthyosis; nerve-injuries may give rise to localized sweat-suppression. treatment is based upon general principles; friction, warm and hot-vapor baths, electricity and similar measures are of service. #bromidrosis.# (_synonym:_ osmidrosis.) #describe bromidrosis.# bromidrosis is a functional disturbance of the sweat-glands characterized by a sweat secretion of an offensive odor. the sweat production may be normal in quantity or more or less excessive, usually the latter. the condition may be local or general, commonly the former. it is closely allied to hyperidrosis, and may often be considered identical, the odor resulting from rapid decomposition of the sweat secretion. the decomposition and resulting odor have been thought due to the presence of bacteria. #what parts are most commonly affected in bromidrosis?# the feet and the axillæ. #what is the treatment of bromidrosis?# it is essentially the same as that of hyperidrosis (_q. v._), consisting of applications of astringent lotions, dusting-powders, especially those containing boric acid and salicylic acid, and the continuous application of diachylon ointment. in obstinate cases weak formaldehyde solutions, röntgen rays, and high-frequency currents can be tried. #chromidrosis.# #describe chromidrosis.# this is a functional disorder of the sweat-glands characterized by a secretion variously colored, and usually increased in quantity. it is, as a rule, limited to a circumscribed area. the most common color is red. the condition is probably of neurotic origin and tends to recur. (true chromidrosis is extremely rare; most of the cases formerly thought to be such are now known to be examples of pseudochromidrosis.) treatment should be invigorating and tonic, with special reference toward the nervous system. the various methods of local electrization should also be resorted to. mild antiseptic and astringent lotions or dusting powders should also be advised. _red chromidrosis_ or _pseudochromidrosis_ is a condition in which the coloring of the sweat occurs after its excretion and is due to the presence of chromatogenous bacteria which are found attached to the hairs of the part in agglutinated masses. the axilla is the favorite site. treatment consists of frequent soap-and-water washings, and the application of boric acid, resorcin, and corrosive sublimate lotions. #uridrosis.# #describe uridrosis.# uridrosis is a rare condition in which the sweat secretion contains the elements of the urine, especially urea. in marked cases the salt may be noticeable upon the skin as a colorless or whitish crystalline deposit. in most instances it has been preceded or accompanied by partial or complete suppression of the renal functions. #phosphoridrosis.# #describe phosphoridrosis.# phosphoridrosis is a rare condition, in which the sweat is phosphorescent. it has been observed in the later stages of phthisis, in miliaria, and in those who have eaten of putrid fish. #seborrh[oe]a (eczema seborrhoicum).# _synonyms:_ (steatorrh[oe]a; acne sebacea; ichthyosis sebacea; dandruff.) #what is seborrh[oe]a?# seborrh[oe]a is a disease of the sebaceous glands, characterized by an excessive and abnormal secretion of sebaceous matter, appearing on the skin as an oily coating, crusts, or scales. in many cases the sweat-glands are likewise implicated, and the process may also be distinctly, although usually mildly, inflammatory. #at what age is seborrh[oe]a usually observed?# between fifteen and forty. it may, however, occur at any age. #name the parts most commonly affected.# the scalp, face, and (less frequently) the sternal and interscapular regions of the trunk. it is sometimes seen on other parts. #what varieties of seborrh[oe]a are encountered?# seborrh[oe]a oleosa and seborrh[oe]a sicca; not infrequently the disease is of a mixed type. #what are the symptoms of seborrh[oe]a oleosa?# the sole symptom is an unnatural oiliness, variable as to degree. its most common sites are the regions of the scalp, nose, and forehead. in many instances mild rosacea coexists with oily seborrh[oe]a of the nose. #give the symptoms of seborrh[oe]a sicca.# a variable degree of greasy scalines, which may be seated upon a pale, hyperæmic or mildly inflammatory surface. the parts affected are covered scantily or more or less abundantly with somewhat greasy, grayish, or brownish-gray scales. if upon the scalp (_dandruff_, _pityriasis capitis_), small particles of scales are found scattered through the hair, and when the latter is brushed or combed, fall over the shoulders. if upon the face, in addition to the scaliness, the sebaceous ducts are usually seen to be enlarged and filled with sebaceous matter. #describe the symptoms of the ordinary or mixed type.# it is common upon the scalp. the skin is covered with irregularly diffused, greasy, grayish or brownish scales and crusts, in some cases moderate in quantity, in others so great that large irregular masses are formed, pasting the hair to the scalp. if removed, the scales and crusts rapidly re-form. the skin beneath is found slate-colored, hyperæmic or mildly inflammatory, and exceptionally it has in places an eczematous aspect (_eczema seborrhoicum_). extraneous matter, such as dust and dirt, collects upon the parts, and the whole mass may become more or less offensive. there is a strong tendency to falling-out of the hair. itching may or may not be present. [illustration: seborrh[oe]a (eczema seborrhoicum).] #describe the symptoms of seborrh[oe]a of the trunk and other parts.# [illustration: fig. 7. a normal sebaceous gland in connection with a lanugo hair. (_after neumann._) _a_, capsule; _b_, fatty secretion; _c_, _h_, secreting cells; _d_, root of lanugo hair; _e_, hair-sac; _f_, hair-shaft; _g_, acini of sebaceous gland.] seborrh[oe]a corporis differs in a measure, in its symptoms, from seborrh[oe]a of the scalp and is usually illustrative of the variety known as eczema seborrhoicum; it occurs as one or several irregular or circinate, slightly hyperæmic or moderately inflammatory patches, covered with dirty or grayish-looking greasy scales or crusts, usually moderate in quantity, and upon removal are found to have projections into the sebaceous ducts. it is commonly seen upon the sternal and interscapular regions. it rarely exists independently in these regions, being usually associated with and following the disease on the scalp. it may also invade the axillæ, genitocrural, and other regions. #what is the usual course of seborrh[oe]a?# essentially chronic, the disease varying in intensity from time to time. in occasional instances it disappears spontaneously. #give the cause or causes of seborrh[oe]a.# general debility, anæmia, chlorosis, dyspepsia, and similar conditions are to be variously looked upon as predisposing. in some instances, however, the disease seems to be purely local in character, and to be entirely independent of any constitutional or predisposing condition. the view recently advanced that the disease is of parasitic nature and contagious has been steadily gaining ground. #what is the pathology of seborrh[oe]a?# seborrh[oe]a is a disease of the sebaceous glands, and probably often involving the sweat-glands also; its products, as found upon the skin, consisting of the sebaceous secretion, epithelial cells from the glands and ducts, and more or less extraneous matter. not infrequently evidences of superficial inflammatory action are also to be found, and it is especially for this type that the name eczema seborrhoicum is most appropriate. in long-continued and neglected cases slight atrophy of the gland-structures may occur. #with what diseases are you likely to confound seborrh[oe]a?# upon the scalp, with eczema and psoriasis; upon the face, with lupus erythematosus and eczema; and upon the trunk, with psoriasis and ringworm. as a rule, the clinical features of seborrh[oe]a are sufficiently characteristic to prevent error. #what are the differential points?# eczema, psoriasis, and lupus erythematosus are diseases in which there are distinct _inflammatory symptoms_, such as thickening and infiltration and redness; moreover, psoriasis, and this holds true as to ringworm also, occurs in sharply-defined, circumscribed patches, and lupus erythematosus has a peculiar violaceous tint and an elevated and marginate border. a microscopic examination of the epidermic scrapings would be of crucial value in differentiating from ringworm. quite frequently, especially in the interscapular and sternal regions, the segmental configuration constitutes an important feature of seborrh[oe]a--of the eczema seborrhoicum variety. #what is the prognosis in seborrh[oe]a?# favorable. all types are curable, and when upon the non-hairy regions, usually readily so; upon the scalp it is often obstinate. relapses are not uncommon. in those cases of seborrh[oe]a capitis which have been long-continued or neglected, and attended with loss of hair, this loss may be more or less permanent, although ordinarily much can be done to promote a regrowth (see _treatment of alopecia_). #how would you treat seborrh[oe]a of the scalp?# by constitutional (if indicated) and local remedies; the former having in view correction or modification of the predisposing factor or factors, and the latter removal of the sebaceous accumulations and the application of mildly stimulating antiseptic ointments or lotions. #what constitutional remedies are commonly employed?# the various tonics, such as iron, quinine, strychnia, cod-liver oil, arsenic, the vegetable bitters, laxatives, malt and similar preparations. the line of treatment is to be based upon indications. #how do you free the scalp of the sebaceous accumulations?# in mild types of the disease shampooing with simple castile soap (or any other good toilet soap) and hot water will suffice; in those cases in which there is considerable scale-and crust-formation the tincture of green soap (tinct. saponis viridis) is to be employed in place of the toilet soap, and in some of these latter cases it may be necessary to soften the crusts with a previous soaking with olive oil. the frequency of the shampoo depends upon the conditions. in mild cases once in five or ten days will be sufficiently frequent to keep the parts clean, but in those cases in which there is rapid scale-or crust-production once daily or every second day may at first be demanded. #name the most effectual applications in seborrh[oe]a capitis.# sulphur, ammoniated mercury, salicylic acid, resorcin, and carbolic acid. sulphur is used in the form of an ointment, from twenty grains to one drachm in the ounce. ammoniated mercury, in the form of an ointment, ten to sixty grains to the ounce. salicylic acid, either alone as an ointment, ten to thirty grains to the ounce; or it may often be added with advantage, in the same proportion, to the sulphur or ammoniated mercury ointment above named. resorcin, either as an ointment, ten to thirty grains to the ounce, or as an alcoholic or aqueous lotion, as the following:- [rx] resorcini ............................ [dram]j-[dram]iss. ol. ricini ........................... [minim]xxx-f[dram]ij. alcoholis ............................ f[oz]iv. m. carbolic acid, to the amount of ten to thirty grains, can be added to this. if an aqueous lotion is desirable, then in the above formula the oleum ricini is replaced with glycerine, and the alcohol with water; three to five minims of glycerine in each ounce is usually sufficient, as a greater quantity makes the resulting lotion sticky. petrolatum alone, or with 10 to 30 per cent. lanolin, is usually the most satisfactory base for the ointments. in some cases of the inflammatory variety the skin is found quite irritable, and the mildest applications are at first only admissible. #how are the remedies to be applied?# a small quantity of the lotion, ointment, or oil is gently applied to the skin; when to the scalp, a lotion or oil can be conveniently applied by means of an eye-dropper. in the beginning of the treatment an application once or twice daily is ordered; later, as the disease becomes less active, once every second or third day. #how is seborrh[oe]a upon other parts to be treated?# in the same general manner as seborrh[oe]a of the scalp, except that the local applications must be somewhat weaker. the several sulphur lotions employed in the treatment of acne (_q. v._) may also be used when the disease is upon these parts. in obstinate patchy cases occasional paintings with a 20 to 50 per cent alcoholic solution of resorcin is curative; following the painting a mild salve should be used. #comedo.# (_synonyms:_ blackheads; flesh-worms.) #what is comedo?# comedo is a disorder of the sebaceous glands, characterized by yellowish or blackish pin-point or pin-head-sized puncta or elevations corresponding to the gland-orifices. #at what age and upon what parts are comedones found?# usually between fifteen and thirty, and upon the face and upper part of the trunk, where they may exist sparsely or in great numbers. they are occasionally associated with oily seborrh[oe]a, the parts presenting a greasy or soiled appearance. exceptionally they occur as distinct, and usually symmetrical, groups upon the forehead or the cheeks. on the upper trunk so-called double and multiple comedo have been noted--the two, three, or even four closely-contiguous blackheads are, beneath the surface, intercommunicable, the dividing duct-walls having apparently disappeared by fusion. #describe an individual lesion.# it is pin-point to pin-head in size, dark yellowish, and usually with a central blackish point (hence the name _blackheads_). there is scarcely perceptible elevation, unless the amount of retained secretion is excessive. upon pressure this may be ejected, the small, rounded orifice through which it is expressed giving it a thread-like shape (hence the name _flesh-worms_). #what is the usual course of comedo?# chronic. the lesions may persist indefinitely or the condition may be somewhat variable. in many instances, either as a result of pressure or in consequence of chemical change in the sebaceous plugs or of the addition of a microbic factor, inflammation is excited and acne results. the two conditions are, in fact, usually associated. [illustration: fig. 8. demodex folliculorum, x 300. ventral surface. (_after simon._)] #to what may comedo often be ascribed?# to disorders of digestion, constipation, chlorosis, menstrual disturbance, lack of tone in the muscular fibres of the skin, the infrequent use of soap, and working in a dirty or dusty atmosphere. a small parasite (_demodex folliculorum_, _acarus folliculorum_) is sometimes found in the sebaceous mass, but its presence is without etiological significance, as it is also found in healthy follicles. a microbacillus has been found by several observers, and credited with etiological influence. #what is the pathology of comedo?# the sebaceous ducts or glands, or both, become blocked up with retained secretion and epithelial cells. the dark points which usually mark the lesions are probably due to accumulation of dirt, but may, as some writers maintain, be due to the presence of pigment-granules resulting from chemical change in the sebaceous matter. #is there any difficulty in the diagnosis of comedo?# no. it can scarcely be confounded with milium, as in this latter disease the lesion has no open outlet, no black point, and the contents cannot be squeezed out. #give the prognosis of comedo.# the result of treatment is usually favorable, although the disease is often rebellious. relapses are not uncommon. #how would you treat a case of comedo?# by systemic (if indicated) and local measures. the constitutional treatment aims at correction or palliation of the predisposing conditions, and the external applications have in view a removal of the sebaceous plugs and stimulation of the glands and skin to healthy action. [illustration: fig. 9. comedo extractor.] #name the systemic remedies commonly employed.# cod-liver oil, iron, quinine, arsenic, nux vomica and other tonics; ergot in those cases in which there is lack of muscular tone, salines and aperient pills in constipation. the digestion is to be looked after and the bowels kept regular; indigestible food of all kinds is to be interdicted. hygienic measures, such as general and local bathing, local massage, calisthenics, and open-air exercise, are of service. #describe the local treatment.# steaming the face or prolonged applications of hot water; washing with ordinary toilet soap and hot water, or, in sluggish cases, using tincture of green soap (tinct. saponis viridis) instead of the toilet soap; removal of the sebaceous plugs by mechanical means, such as lateral pressure with the finger ends or perpendicular pressure with a watch-key with rounded edges, or with an instrument specially contrived for this purpose; and after these preliminary measures, which should be carried out every night, a stimulating sulphur ointment or lotion, such as employed in the treatment of acne (_q. v._), is to be thoroughly applied. the following is valuable:- [rx] zinci sulphatis, potassi sulphureti, .

[illustration: fig. 10. milium needle.] in rare instances they may undergo calcareous metamorphosis, constituting the so-called _cutaneous calculi_. #what is the anatomical seat of milium?# the sebaceous gland (probably one or several of the superficially-situated acini), the duct of which is in some manner obliterated, the sebaceous matter collects, becomes inspissated and calcareous, forming the pin-head lesion. the epidermis is the external covering. #what is the treatment?# the usual plan is to prick or incise each lesion and press out the contents. in some milia it may be necessary also, in order to prevent a return, to touch the base of the excavation with tincture of iodine or with silver nitrate. electrolysis is also effectual. in those cases where the lesions are numerous the production of exfoliation of the epiderm by means of resorcin applications (see acne) is a good plan. #steatoma.# (_synonyms:_ sebaceous cyst; sebaceous tumor; wen.) #describe steatoma.# steatoma, or sebaceous cyst, appears as a variously-sized, elevated, rounded or semi-globular, soft or firm tumor, freely movable and painless, and having its seat in the corium or subcutaneous tissue. the overlying skin is normal in color, or it may be whitish or pale from distention; in some a gland-duct orifice may be seen, but, as a rule, this is absent. #what are the favorite regions for the development of steatoma?# the scalp, face and back. one or several may be present. #what is the course of sebaceous cysts?# their growth is slow, and, after attaining a variable size, may remain stationary. they may exist indefinitely without causing any inconvenience beyond the disfigurement. exceptionally, in enormously distended growths, suppuration and ulceration result. #what is the pathology?# a steatoma is a cyst of the sebaceous gland and duct, produced by retained secretion. the contents may be hard and friable, soft and cheesy, or even fluid, of a grayish, whitish or yellowish color, and with or without a fetid odor; the mass consisting of fat-drops, epidermic cells, cholesterin, and sometimes hairs. #are sebaceous cysts likely to be confounded with gummata?# no. gummata grow more rapidly, are usually painful to the touch, are not freely movable, and tend to break down and ulcerate. #describe the treatment of steatoma.# a linear incision is made, and the mass and enveloping sac dissected out. if the sac is permitted to remain, reproduction almost invariably takes place. #class ii.--inflammations.# #erythema simplex.# #what do you understand by erythema simplex?# erythema simplex is a hyperæmic disorder characterized by redness, occurring in the form of variously-sized and shaped, diffused or circumscribed, non-elevated patches. #name the two general classes into which the simple erythemata are divided.# idiopathic and symptomatic. #what do you include in the idiopathic class?# those erythemas due to external causes, such as cold and heat (_erythema caloricum_), the action of the sun (_erythema solare_), traumatism (_erythema traumaticum_), and the various poisons or chemical irritants (_erythema venenatum_). #what do you include in the symptomatic class?# those rashes often preceding or accompanying certain of the systemic diseases, and those due to disorders of the digestive tract, stomachic and intestinal toxins, to the ingestion of certain drugs, and to use of the therapeutic serums. #describe the symptoms of erythema simplex.# the essential symptom is redness--simple hyperæmia--without elevation or infiltration, disappearing under pressure, and sometimes attended by slight heat or burning; it may be patchy or diffused. in the idiopathic class, if the cause is continued, dermatitis may result. #what is to be said about the distribution of the simple erythemata?# the idiopathic rashes, as inferred from the nature of the causes, are usually limited. the symptomatic erythemas are more or less generalized; desquamation sometimes follows. #describe the treatment of the simple erythemata.# a removal of the cause in idiopathic rashes is all that is needed, the erythema sooner or later subsiding. the same may be stated of the symptomatic erythemata, but in these there is at times difficulty in recognizing the etiological factor; constitutional treatment, if necessary, is to be based upon general principles. intestinal antiseptics are useful in some instances. local treatment, which is rarely needed, consists of the use of dusting-powders or mild cooling and astringent lotions, such as are employed in the treatment of acute eczema (q. v.). #erythema intertrigo.# (_synonym:_ chafing.) #what do you understand by erythema intertrigo?# erythema intertrigo is a hyperæmic disorder occurring on parts where the natural folds of the skin come in contact, and is characterized by redness, to which may be added an abraded surface and maceration of the epidermis. #describe the symptoms of erythema intertrigo.# the skin of the involved region gradually becomes hyperæmic, but is without elevation or infiltration; a feeling of heat and soreness is usually experienced. if the condition continue, the increased perspiration and moisture of the parts give rise to maceration of the epidermis and a mucoid discharge; actual inflammation may eventually result. #what is the course of erythema intertrigo?# the affection may pass away in a few days or persist several weeks, the duration depending, in a great measure, upon the cause. #mention the causes of erythema intertrigo.# the causes are usually local. it is seen chiefly in children, especially in fat subjects, in whom friction and moisture of contiguous parts of the body, usually the region of the neck, buttocks and genitalia, are more common; in such, uncleanliness or the too free use of soap washings will often act as the exciting factor. disorders of the stomach or intestinal canal apparently have a predisposing influence. #what treatment would you advise in erythema intertrigo?# the folds or parts are to be kept from contact by means of lint or absorbent cotton; thin, flat bags of cheese cloth or similar material partly filled with dusting-powder, and kept clean by frequent changes, are excellent for this purpose, and usually curative. cleanliness is essential, but it is to be kept within the bounds of common sense. dusting-powders and cooling and astringent lotions, such as are employed in the treatment of acute eczema (_q. v._), can also be advised. the following lotion is valuable:- [rx] pulv. calaminæ, pulv. zinci oxidi, .. [=a][=a] ...... [dram]iss. glycerinæ, .......................... [minum]xxx alcoholis, .......................... f[dram]ij aquæ, ............................... oss. m. exceptionally a mild ointment, alone or supplementary to a lotion, acts more satisfactorily. in persistent or obstinate cases attention should also be directed to the state of the general health, especially as regards the digestive tract. #erythema multiforme.# #what is erythema multiforme?# erythema multiforme is an acute, inflammatory disease, characterized by reddish, more or less variegated macules, papules, and tubercles, occurring as discrete lesions or in patches of various size and shape. #upon what parts of the body does the eruption appear?# usually upon the extremities, especially the dorsal aspect, from the knees and elbows down, and about the face and neck; it may, however, be more or less general. #describe the symptoms of erythema multiforme.# with or without precursory symptoms of malaise, gastric uneasiness or rheumatic pains, the eruption suddenly makes its appearance, assuming an erythematous, papular, tubercular or mixed character; as a rule, one type of lesion predominates. the lesions tend to increase in size and intensity, remain stationary for several days or a week, and then gradually fade; during this time there may have been outbreaks of new lesions. in color they are pink, red, or violaceous. slight itching may or may not be present. exceptionally, in general cases, the eruption partakes of the nature of both urticaria and erythema multiforme, and itching may be quite a decided symptom. in some instances there is preceding and accompanying febrile action, usually slight in character; in others there may be some rheumatic swelling of one or more joints. [illustration: fig. 11. erythema multiforme, in which many of the lesions have become bullous--erythema bullosum.] #what type of the eruption is most common?# the papular, appearing usually upon the backs of the hands and forearms, and not infrequently, also, upon the face, legs and feet. the papules are usually pea-sized, flattened, and of a dark red or violaceous color. #describe the various shapes which the erythematous lesions may assume.# often the patches are distinctly ring-shaped, with a clear centre--_erythema annulare_; or they are made up of several concentric rings, presenting variegated coloring--_erythema iris_; or a more or less extensive patch may spread with a sharply-defined border, the older part tending to fade--_erythema marginatum_; or several rings may coalesce, with a disappearance of the coalescing parts, and serpentine lines or bands result--_erythema gyratum_. #does the eruption of erythema multiforme ever assume a vesicular or bullous character?# yes. in exceptional instances, the inflammatory process may be sufficiently intense to produce vesiculation, usually at the summits of the papules--_erythema vesiculosum_; and in some instances, blebs may be formed--_erythema bullosum_. a vesicular or bullous lesion may become immediately surrounded by a ring-like vesicle or bleb, and outside of this another form; a patch may be made up of as many as several such rings--_herpes iris_. in the vesicular and bullous cases the lips and the mucous membranes of the mouth and nose also may be the seat of similar lesions. #what is the course of erythema multiforme?# acute, the symptoms disappearing spontaneously, usually in one to three or four weeks. in some instances the recurrences take place so rapidly that the disease assumes a chronic aspect; it is possible that such cases are midway cases between this disease and dermatitis herpetiformis. #mention the etiological factors in erythema multiforme.# the causes are obscure. digestive disturbance, rheumatic conditions, and the ingestion of certain drugs are at times influential. intestinal toxins are doubtless important etiological factors in some cases. certain foods, such as are apt to undergo rapid putrefactive or fermentative change, especially pork meats, oysters, fish, crabs, lobsters, etc., are, therefore, not infrequently of apparent causative influence. it is most frequently observed in spring and autumn months, and in early adult life. the disease is not uncommon. #what is the pathology of erythema multiforme?# it is a mildly inflammatory disorder, somewhat similar to urticaria, and presumably due to vasomotor disturbance; the amount of exudation, which is variable, determines the character of the lesions. #name the diagnostic points of erythema multiforme.# the multiformity of the eruption, the size of the papules, often its limitation to certain parts, its course and the entire or comparative absence of itching. it resembles urticaria at times, but the lesions of this latter disease are evanescent, disappearing and reappearing usually in the most capricious manner, are commonly seated about the trunk, and are exceedingly itchy. in the vesicular and bullous types the acute character of the outbreak, the often segmental and ring-like shape, their frequent origin from erythematous papules, and the distribution and association with the more common manifestations, are always suggestive. #what prognosis would you give in erythema multiforme?# always favorable; the eruption usually disappears in ten days to three weeks, although in rare instances new crops may appear from day to day or week to week, and the process last one or two months. one or more recurrences in succeeding years are not uncommon. those rare cases in which vesicular or bullous lesions are also seen on the lips and in the mouth, are more prone to longer duration and to more frequent recurrences. #what remedies are commonly prescribed in erythema multiforme?# quinin, and, if constipation is present, saline laxatives. calcined magnesia is valuable as a laxative. intestinal antiseptics, such as salol, thymol, and sodium salicylate, are valuable in cases probably due to intestinal toxins. in those exceptional instances in which there may be associated febrile action and rheumatic swelling of the joints, the patient should be kept in bed till these symptoms subside. local applications are rarely required, but in those exceptional cases in which itching or burning is present, cooling lotions of alcohol and water or vinegar and water are to be prescribed. the vesicular and bullous types demand mild protective applications, such as used in eczema and pemphigus. #erythema nodosum.# (_synonym:_ dermatitis contusiformis.) #what is erythema nodosum?# erythema nodosum is an inflammatory affection, of an acute type, characterized by the formation of variously-sized, roundish, more or less elevated erythematous nodes. #is there any special region of predilection for the eruption of erythema nodosum?# yes. the tibial surfaces, to which the eruption is often limited; not infrequently, however, other parts may be involved, more especially the arms and forearms. #describe the symptoms of erythema nodosum.# the eruption makes its appearance suddenly, and is usually ushered in with febrile disturbance, gastric uneasiness, malaise, and rheumatic pains and swelling about the joints. the lesions vary in size from a cherry to a hen's egg, are rounded or ovalish, tender and painful, have a glistening and tense look, and are of a bright red, erysipelatous color which merges gradually into the sound skin. at first they are somewhat hard, but later they soften and appear as if about to break down, but this, however, never occurs, absorption invariably taking place. in occasional instances they are hemorrhagic. exceptionally the lesions of erythema multiforme are also present. lymphangitis is sometimes observed. in rare instances symptoms pointing to visceral involvement, to cerebral invasion, and to heart complications have been observed. #are the lesions in erythema nodosum usually numerous?# no. as a rule not more than five to twenty nodes are present. #what is the course of erythema nodosum?# acute. the disease terminating usually in one to three weeks. as the lesions are disappearing they present the various changes of color observed in an ordinary bruise. #what is known in regard to the etiology?# the affection is closely allied to erythema multiforme, and is, indeed, by some considered a form of that disease. it occurs most frequently in children and young adults, and usually in the spring and autumn months. intestinal toxins are thought responsible in some cases. digestive disturbance and rheumatic pain and swellings are often associated with it. by many the malady is thought to be a specific infection. #what is the pathology of erythema nodosum?# the disease is to be viewed as an inflammatory [oe]dema, probably resulting, in some instances at least, from an inflammation of the lymphatics or an embolism of the cutaneous vessels. #what diseases may erythema nodosum resemble?# bruises, abscesses, and gummata. #how are the lesions of erythema nodosum to be distinguished from these several conditions?# by the bright red or rosy tint, the apparently violent character of the process, the number, situation and course of the lesions. #state the prognosis of erythema nodosum.# favorable, recovery usually taking place in ten days to several weeks. #state the treatment to be advised in erythema nodosum.# rest, relative or absolute, depending upon the severity of the case, and an unstimulating diet; internally intestinal antiseptics, quinin and saline laxatives, and locally applications of lead-water and laudanum. #erythema induratum.# (_synonym:_ erythema induratum scrofulosorum.) #what do you understand by erythema induratum?# a rare disease characterized in the beginning by one or more usually deep-seated nodules, and, as a rule, seated in the legs, especially the calf region. the nodules gradually enlarge, the skin becomes reddish, violaceous or livid in color. absorption may take place slowly, or the indurations may break down, resulting in an indolent, rather deep-seated ulcer, closely resembling a gummatous ulcer. the disease is slow and persistent, and is commonly met with in girls and young women, usually of strumous type. it suggests a tuberculous origin. treatment consists in administration of cod-liver oil, phosphorus and other tonics. rest is of service. locally antiseptic applications, and support with roller bandage are to be advised. #urticaria.# (_synonyms:_ hives; nettlerash.) #give a definition of urticaria.# urticaria is an inflammatory affection characterized by evanescent whitish, pinkish or reddish elevations, or wheals, variable as to size and shape, and attended by itching, stinging or pricking sensations. #describe the symptoms of urticaria.# the eruption, erythematous in character and consisting of isolated pea or bean-sized elevations or of linear streaks or irregular patches, limited or more or less general, and usually intensely itchy, makes its appearance suddenly, with or without symptoms of preceding gastric derangement. the lesions are soft or firm, reddish or pinkish-white, with the peripheral portion of a bright red color, and are fugacious in character, disappearing and reappearing in the most capricious manner. in many cases simply drawing the finger over the skin will bring out irregular and linear wheals. in exceptional cases this peculiar property is so pronounced and constant that at any time letters and other symbols may be produced at will, even when such subjects are free from the ordinary urticarial lesions (_urticaria factitia_, _dermatographism_, _autographism_). the mucous membrane of the mouth and throat may also be the seat of wheals and urticarial swellings. #what is the ordinary course of urticaria?# acute. the disease is usually at an end in several hours or days. #does urticaria always pursue an acute course?# no. in exceptional instances the disease is chronic, in the sense that new lesions continue to appear and disappear irregularly from time to time for months or several years, the skin rarely being entirely free (_chronic urticaria_). [illustration: fig. 12. dermatographism. (_after c.n. davis._)] #are subjective symptoms always present in urticaria?# yes. itching is commonly a conspicuous symptom, although at times pricking, stinging or a feeling of burning constitutes the chief sensation. #in what way may the eruption be atypical?# exceptionally the wheals, or lesions, are peculiar as to formation, or another condition or disease may be associated, hence the varieties known as urticaria papulosa, urticaria hæmorrhagica, urticaria tuberosa, and urticaria bullosa. #describe urticaria papulosa.# urticaria papulosa (formerly called _lichen urticatus_) is a variety in which the lesions are small and papular, developing usually out of the ordinary wheals. they appear as a rule suddenly, rarely in great numbers, are scattered, and after a few hours or, more commonly, days gradually disappear. the itching is intense, and in consequence their apices are excoriated. sometimes the papules are capped with a small vesicle (vesicular urticaria). it is seen more particularly in ill-cared for and badly-nourished young children. #describe urticaria hæmorrhagica.# urticaria hæmorrhagica is characterized by lesions similar to ordinary wheals, except that they are somewhat hemorrhagic, partaking, in fact, of the nature of both urticaria and purpura. #describe urticaria tuberosa.# in urticaria tuberosa the lesions, instead of being peaor bean-sized, as in typical urticaria, are large and node-like (also called _giant urticaria_). #what is acute-circumscribed [oe]dema?# in rare instances there occurs, along with the ordinary lesions of the disease or as its sole manifestation, sudden and evanescent swelling of the eyelids, ears, lips, tongue, hands, fingers, or feet (_urticaria [oe]dematosa_, _acute_ _circumscribed [oe]dema_, _angioneurotic [oe]dema_). one or several of these parts only may be affected at the one attack; in recurrences, so usual in this variety, the same or other parts may exhibit the manifestation. (these [oe]dematous swellings occurring alone might be looked upon, as they are by most observers, as an independent affection, but its close relationship to ordinary urticaria is often evident.) #describe urticaria bullosa.# urticaria bullosa is a variety in which the inflammatory action has been sufficiently great to give rise to fluid exudation, the wheals resulting in the formation of blebs. #what is the etiology of urticaria?# any irritation from disease, functional or organic, of any internal organ, may give rise to the eruption in those predisposed. gastric derangement from indigestible or peculiar articles of food, intestinal toxins, and the ingestion of certain drugs are often provocative. the so-called "shell-fish" group of foods play an important etiological part in some cases. idiosyncrasy to certain articles of food is also responsible in occasional instances. various rheumatic and nervous disorders are not infrequently associated with it, and are doubtless of etiological significance. external irritants, also, in predisposed subjects, are at times responsible. #what is the pathology of urticaria?# anatomically a wheal is seen to be a more or less firm elevation consisting of a circumscribed or somewhat diffused collection of semi-fluid material in the upper layers of the skin. the vasomotor nervous system is probably the main factor in its production; dilatation following spasm of the vessels results in effusion, and in consequence, the overfilled vessels of the central portion are emptied by pressure of the exudation and the central paleness results, while the pressed-back blood gives rise to the bright red periphery. #from what diseases is urticaria to be differentiated?# from erythema simplex, erythema multiforme, erythema nodosum, and erysipelas. #mention the diagnostic points of urticaria.# the acuteness, character of the lesions, their evanescent nature, the irregular or general distribution, and the intense itching. #what is the prognosis in urticaria?# the acute disease is usually of short duration, disappearing spontaneously or as the result of treatment, in several hours or days; it may recur upon exposure to the exciting cause. the prognosis of chronic urticaria is to be guarded, and will depend upon the ability to discover and remove or modify the predisposing condition. #what systemic measures are to be prescribed in acute urticaria?# removal of the etiological factor is of first importance. this will be found in most cases to be gastric disturbance from the ingestion of improper or indigestible food, and in such cases a saline purgative is to be given, probably the best for this purpose being the laxative antacid, magnesia; or if the case is severe and food is still in the stomach, an emetic, such as mustard or ipecac, will act more promptly. alkalies, especially sodium salicylate, and intestinal antiseptics are useful. calcium chloride in doses of five to twenty grains should be tried in obstinate cases. the diet should be, for the time, of a simple character. #what systemic measures are to be prescribed in chronic and recurrent urticaria?# the cause must be sought for and treatment directed toward its removal or modification. treatment will, therefore, depend upon indications. in obscure cases, quinine, sodium salicylate, arsenic, pilocarpine, _atropia_, potassium bromide, calcium chloride, and ichthyol are to be variously tried; general galvanization is at times useful, as is also a change of scene and climate. a proper dietary and the maintenance of free action of the bowels, preferably, as a rule, with a saline laxative, is of great importance in these chronic cases. in acute circumscribed [oe]dema treatment is essentially that of urticaria, the diet being given special attention. #what external applications would you advise for the relief of the subjective symptoms?# cooling lotions of alcohol and water or vinegar and water; lotions of carbolic acid, one to three drachms to the pint; of thymol, one-fourth to one drachm to the pint of alcohol and water; of liquor carbonis detergens, one to three ounces to the pint of water, or the following:- [rx] acidi carbolici, ..................... [dram]j-[dram]iij acidi borici, ........................ [dram]iv glycerinæ, ........................... f[dram]j alcoholis, ........................... f[oz]ij aquæ, ................................ f[oz]xiv. m. alkaline baths are also useful, and may advantageously be followed by dusting-powders of starch and zinc oxide. #urticaria pigmentosa.# (_synonym:_ xanthelasmoidea.) #describe urticaria pigmentosa.# urticaria pigmentosa is a rare disease, variously viewed as an unusual form of urticaria and as an urticaria-like eruption in which there is an element of new growth in the lesions. it begins usually in infancy or early childhood and continues for months or years, and is characterized by slightly, moderately, or intensely itchy, wheal-like elevations, which are more or less persistent and leave yellowish, orange-colored, greenish or brownish stains. exceptionally subjective symptoms are almost entirely absent. anatomical studies show that the lesion has in some respects the structure of an ordinary wheal, with [oe]dema and pigment deposit in the epidermal portion, and cellular infiltration made up principally of mast-cells. [illustration: fig. 13. urticaria pigmentosa.] the nature of the disease is obscure and treatment unsatisfactory. ordinarily as early youth or adult life is reached it spontaneously disappears. the treatment advised is usually on the same lines as that of chronic urticaria. #dermatitis.# #what is implied by the term dermatitis?# dermatitis, or inflammation of the skin, is a term employed to designate those cases of cutaneous disturbance, usually acute in character, which are due to the action of irritants. #mention some examples of cutaneous disturbance to which this term is applied.# the dermatic inflammation due to the action of excessive heat or cold, to caustics and other chemical irritants, and to the ingestion of certain drugs. #what several varieties are commonly described?# dermatitis traumatica, dermatitis calorica, dermatitis venenata, and dermatitis medicamentosa. #describe dermatitis traumatica.# under this head are included all forms of cutaneous inflammation due to traumatism. to the dermatologist the most common met with is that produced by the various animal parasites and from continued scratching; in such, if the cause has been long-continued and persistent, a variable degree of inflammatory thickening of the skin and pigmentation result, the latter not infrequently being more or less permanent. the inflammation due to tight-fitting garments, bandages, to constant pressure (as bed-sores), etc., also illustrates this class. #what is the treatment of dermatitis traumatica?# removal of the cause, and, if necessary, the application of soothing ointments or lotions; in bed-sores, soap plaster, plain or with one to five per cent. of ichthyol. #what is dermatitis calorica?# cutaneous inflammation, varying from a slight erythematous to a gangrenous character, produced by excessive heat (_dermatitis ambustionis_, _burns_) or cold (_dermatitis congelationis_, _frostbite_). #give the treatment of dermatitis calorica.# in burns, if of a mild degree, the application of sodium bicarbonate, as a powder or saturated solution, is useful; in the more severe grade, a twoto five-per-cent. solution will probably be found of greater advantage. other soothing applications may also be employed. in recent years a one-per-cent. solution of picric acid has been commended for the slighter burns of limited extent. upon the whole, there is nothing yet so generally useful and soothing in these cases as the so-called carron oil; in some cases more valuable with 1/2 to 1 minim of carbolic acid added to each ounce. in frostbite, seen immediately after exposure, the parts are to be brought gradually back to a normal temperature, at first by rubbing with snow or applying cold water. subsequently, in ordinary chilblains, stimulating applications, such as oil of turpentine, balsam of peru, tincture of iodine, ichthyol, and strongly carbolized ointments are of most benefit. if the frostbite is of a vesicular, pustular, bullous, or escharotic character, the treatment consists in the application of soothing remedies, such as are employed in other like inflammatory conditions. #what do you understand by dermatitis venenata?# all inflammatory conditions of the skin due to contact with deleterious substances such as caustic, chemical irritants, iodoform, etc., are included under this head, but the most common causes are the rhus plants--_poison ivy_ (or _poison oak_) and _poison sumach_ (_poison dogwood_). mere proximity to these plants will, in some individuals, provoke cutaneous disturbance (_rhus poisoning_, _ivy poisoning_), although they may be handled by others with impunity. many other plants are also known to produce cutaneous irritation in certain subjects; among these may be mentioned the nettle, primrose, cowhage, smartweed, balm of gilead, oleander, and rue. the local action of iodoform (_iodoform dermatitis_) in some individuals is that of a decided irritant, bringing about a dermatitis, which often spreads much beyond the parts of application, and which in those eczematously inclined may result in a veritable and persistent eczema. #describe the symptoms of rhus poisoning.# the symptoms appear usually soon after exposure, and consist of an inflammatory condition of the skin of an eczematous nature, varying in degree from an erythematous to a bullous character, and with or without [oe]dema and swelling. as a rule, marked itching and burning are present. the face, hands, forearms and genitalia are favorite parts, although it may in many instances involve a greater portion of the whole surface. #what is the course of rhus poisoning?# it runs an acute course, terminating in recovery in one to six weeks. in those eczematously inclined, however, it may result in a veritable and persistent form of that disease. #how would you treat rhus poisoning?# by soothing and astringent applications, such as are employed in acute eczema (_q. v._), which are to be used freely. among the most valuable are: a lotion of fluid extract of grindelia robusta, one to two drachms to four ounces of water; lotio nigra, either alone or followed by the oxide-of-zinc ointment; a saturated solution of boric acid, with a half to two drachms of carbolic acid to the pint; a lotion of zinc sulphate, a half to four grains to the ounce; weak alkaline lotions; cold cream, petrolatum, and oxide-of-zinc ointments. #how would you treat the dermatitis due to other deleterious substances of this class?# by applications of a soothing and protective character, similar to those used in eczema and burns. #dermatitis medicamentosa.# #what do you understand by dermatitis medicamentosa?# under this head are included all eruptions due to the ingestion or absorption of certain drugs. in rare instances one dose will have such effect; commonly, however, it results only after several days' or weeks' continued administration. with some drugs such effect is the rule, with others it is exceptional, nor are all individuals equally susceptible. #how is the eruption produced in dermatitis medicamentosa?# in some instances it is probably due to the elimination of the drug through the cutaneous structures; in others, to the action of the drug upon the nervous system. the view that the drug acts as a toxin or generates some toxin or irritant material in the blood, to which the eruptive phenomena may be due, has also been advanced. [illustration: dermatitis medicamentosa. bullous dermatitis from iodide of potassium.] #what is the character of the eruption in dermatitis medicamentosa?# it may be erythematous, papular, urticarial, vesicular, pustular or bullous, and, if the administration of the drug is continued, even gangrenous. #name the more common drugs having such action.# antipyrin, arsenic, atropia (or belladonna), bromides, chloral, copaiba, cubebs, digitalis, iodides, mercury, opium (or morphia), quinine, salicylic acid, stramonium, acetanilid, sulphonal, phenacetin, turpentine, many of the new coal-tar derivatives, etc. #state frequency and types of eruption due to the ingestion of antipyrin.# not uncommon. _erythematous_, morbilliform and erythemato-papular; itching is usually present and moderate desquamation may follow. acetanilid, sulphonal, phenacetin, and other drugs of this class may provoke like eruptions. #mention frequency and types of eruption due to the ingestion of arsenic.# rare. erythematous, erythemato-papular; exceptionally, herpetic, and pigmentary. herpes zoster has been thought to follow its use. keratosis of the palms and soles has also been occasionally observed, which, in rare instances, has developed into epithelioma. #mention frequency and types of eruption due to the ingestion of atropia (or belladonna).# not uncommon. _erythematous_ and _scarlatinoid_; usually no febrile disturbance, and desquamation seldom follows. #give frequency and types of cutaneous disturbance following the administration of the bromides (bromine).# common. _pustular_, sometimes furuncular and carbuncular and superficially ulcerative. in exceptional instances papillomatous or vegetating lesions have been observed. co-administration of arsenic or potassium bitartrate is thought to have a preventive influence in some cases. #state frequency and types of cutaneous disturbance due to the administration of chloral.# occasional. scarlatinoid and urticarial, and exceptionally purpuric; in rare instances, if drug is continued, eruption becomes vesicular, hemorrhagic, ulcerative and even gangrenous. #state frequency and types of eruption following the administration of copaiba.# not uncommon. _urticarial_, erythemato-papular and _scarlatinoid_. #mention frequency and types of eruption resulting from the ingestion of cubebs.# uncommon. erythematous and small papular. [illustration: fig. 14. a somewhat rare form of eruption from the ingestion of iodine compounds. (_after j.c. mcguire._)] #mention frequency and types of eruption resulting from the administration of digitalis.# exceptional. scarlatinoid and papular. #state frequency and types of eruption resulting from the iodides (iodine).# common. _pustular_, but may be erythematous, papular, vesicular, bullous, tuberous, purpuric and hemorrhagic. co-administration of arsenic or potassium bitartrate is thought to have a preventive influence in some cases. #give the frequency and types of eruption observed to follow the administration of mercury.# exceptional. erythematous and erysipelatous. #give the frequency and types of the cutaneous disturbance following the ingestion of opium (or morphia).# not uncommon. erythematous and _scarlatinoid_, and sometimes urticarial. #mention the frequency and the types of eruption following the administration of quinine.# not infrequent. usually _erythematous_, but may be urticarial, erythemato-papular, and even purpuric. there is, in some instances, preceding or accompanying systemic disturbance. furfuraceous or lamellar desquamation often follows. #state frequency and types of eruption resulting from the ingestion of salicylic acid.# not common. erythematous and urticarial; exceptionally, vesicular, pustular, bullous, and ecchymotic. #give frequency and type of cutaneous disturbance due to the administration of stramonium.# not common. erythematous. #state frequency and types of eruption resulting from the administration of turpentine.# not uncommon. _erythematous_, and small-papular; exceptionally vesicular. #x-ray dermatitis.# #what several grades of x-ray dermatitis (x-ray burns, rontgen-ray burns) are observed?# three grades are usually described: erythema, superficial vesication, and necrosis. the first and second may come on shortly--a few hours to several days--after exposure; occasionally later. the third grade may present also in the first several days, but in many cases one to several weeks may elapse before it appears; it is quite commonly preceded by erythema and vesication. the necrosis may be superficial or deep, and quite usually results in a persistent ulcer covered by a leathery coating; it is usually painful. [illustration: fig. 15. _x_-ray burn] #give the prognosis and treatment of x-ray dermatitis.# the first grade--the erythematous--usually disappears in one to ten days; the second grade requires one to several weeks, and may be quite sore and tender; the severe or necrotic burns are persistent, sometimes lasting for months and several years, with little tendency to spontaneous disappearance, and rebellious to treatment. treatment of the milder types is that of erythema (_q. v._); the necrotic type occasionally demands thorough curetting and skin-grafting before it will heal. #dermatitis factitia.# (_synonym:_ feigned eruptions.) #what do you understand by feigned eruptions?# feigned, or artificial, eruptions, occasionally met with in hysterical females and in others, are produced, for the purpose of exciting sympathy or of deception, by the action of friction, cantharides, acids or strong alkalies; the cutaneous disturbance may, therefore, be erythematous, vesicular, bullous, or gangrenous. it is usually limited in extent, and, as a rule, seen only on parts easily reached by the hands. [illustration: fig. 16. dermatitis factitia--note the unusually uniform and regular character and arrangement of the lesions.] #dermatitis gangrænosa.# #what do you understand by dermatitis gangrænosa?# dermatitis gangrænosa (_erythema gangrænosum_, _raynaud's disease_, _spontaneous gangrene_) is an exceedingly rare affection, characterized by the formation of gangrenous spots and patches. it may be idiopathic or symptomatic. some of these cases, especially in hysterical subjects, belong under the "feigned eruptions," being self-produced. as an idiopathic disease, it begins as erythematous, dark-red spots--usually preceded and accompanied by mild or grave systemic disturbance--which gradually pass into gangrene and sloughing; the eventual termination may be fatal, or recovery may take place. as a symptomatic disease, it is occasionally met with in diabetes and in grave cerebral and spinal affections. in raynaud's disease (symmetric gangrene) the parts affected are the extremities, such as fingers and toes, the ears and nose, only occasionally other parts. the first symptoms observed are coldness and paleness of the part; followed sooner or later by congestion of a dark red, livid, or bluish color, with sometimes swelling, and tenderness and shooting pains. the termination is usually in gangrene of a dry character, with, in some instances, vesicles and blebs along the edges; in other cases the parts become atrophied, withered, and indurated. treatment is based upon general principles. #erysipelas.# #what is erysipelas?# erysipelas is an acute specific inflammation of the skin and subcutaneous tissue, commonly of the face, characterized by shining redness, swelling, [oe]dema, heat, and a tendency in some cases to vesicleand bleb-formation, and accompanied by more or less febrile disturbance. #describe the symptoms and course of erysipelas.# a decided rigor or a feeling of chilliness followed by febrile action usually ushers in the cutaneous disturbance. the skin at a certain point or part, commonly where there is a lesion of continuity, becomes bright red and swollen; this spreads by peripheral extension, and in the course of several hours involves a portion or the whole region. the parts are shining red, swollen, of an elevated temperature, and sharply defined against the sound skin. after several days or a week, during which time there is usually continued mild or severe febrile action, the process begins to subside, and is followed by epidermic desquamation. in some cases vesicles and blebs may be present; in other cases the disease seriously involves the deeper parts, and is accompanied by grave constitutional symptoms. in exceptional instances sloughing takes place. a mild, transitory, limited, and often recurrent erysipelatous condition of the outlet and immediate neighborhood of one or both nostrils is met with, taking its origin from an inflammation of the hair-follicles just inside the margin of the nose; constitutional symptoms are usually wanting. somewhat similar, doubtless, is the erysipelatous inflammation (_erysipeloid_) observed on the fingers and hands of butchers, etc., starting from a wound, apparently as a result of infection from putrid meat or fish. #what is erysipelas migrans (or erysipelas ambulans)?# a variety of erysipelas which, after a few hours or days, disappears at one region and appears at another, and so continues for one or several weeks. #what is the cause of erysipelas?# the disease is due to a specific streptococcus--the streptococcus of fehleisen. depression of the vital forces and local abrasions are predisposing factors. #state the diagnostic points.# the character of the onset, the shining redness and swelling, the sharply-defined border, and the accompanying febrile disturbance. #what is the prognosis in erysipelas?# in most instances the disease runs a favorable course, terminating in recovery in one to three weeks. exceptionally, in severe cases, a fatal termination ensues. #what is the treatment of erysipelas?# _internally_, a purge, followed by the tincture of the chloride of iron and quinia, and stimulants if needed. _locally_, one to three per cent. carbolic-acid lotion or ointment, a saturated solution of boric acid, or a tento twenty-per-cent. aqueous solution or ointment of ichthyol may be employed. in some cases the spread of the disease is apparently controlled by painting the bordering healthy skin with a ring of tincture of iodine or strong solution of nitrate of silver. #phlegmona diffusa.# #what do you understand by phlegmona diffusa?# phlegmona diffusa is a more or less extensive inflammation of the cutaneous and subcutaneous tissues presenting symptoms partaking of the nature of both deep erysipelas and flat carbuncles, and usually attended with varying constitutional disturbance. suppuration at several points takes place, and sloughing may ensue. recovery usually finally results, but a fatal issue is possible. treatment is based upon general principles. #furunculus.# (_synonyms:_ furuncle; boil.) #define furunculus.# furunculus, or boil, is an acute, deep-seated, inflammatory, circumscribed, rounded or more or less acuminated, firm, painful formation, usually terminating in central suppuration. #describe the symptoms and course.# a boil begins as a small, rounded or imperfectly defined reddish spot, or as a small, superficial pustule; it increases in size, and when well advanced appears as a pea or cherry-sized, circumscribed, reddish elevation, with more or less surrounding hyperæmia and swelling; it is painful and tender, and ends, in the course of several days or a week, in the formation of a central slough or "_core_," which finally involves the central overlying skin (_pointing_). one or several may be present, gradually maturing and disappearing. insignificant scarring may remain. in some cases sympathetic constitutional disturbance is noticed. #what is a blind boil?# a sluggish boil exhibiting little, if any, tendency to point or break. #what is furunculosis?# furunculosis is that condition in which boils, singly or in crops, continue to appear, irregularly, for weeks or months. #state the etiology of furuncle.# a depraved state of the general health is often to be considered as a predisposing factor. persistent furunculosis is not infrequent in diabetes mellitus. the immediate exciting cause is the entrance into the follicle of a microbe, the staphylococcus pyogenes aureus. it is not improbable, however, that boils may also be due to other pus-producing organisms. workmen in paraffin oils or other petroleum products often present numerous furuncles and cutaneous abscesses. conditions favoring a persistent miliaria have also a causative influence, especially observed in infants and young children. in these latter, especially among the poorer classes, sluggish boils or subcutaneous abscesses about the scalp in hot weather, are not at all infrequent. #what is the pathology of furuncle?# a boil is an inflammatory formation having its starting point in a sebaceous-gland, sweat-gland, or hair-follicle. the core, or central slough, is composed of pus and of the tissue of the gland in which it had its origin. #how would you distinguish a boil from a carbuncle?# a boil is comparatively small, rounded or acuminate, and has but one point of suppuration; a carbuncle is large, flattened, intensely painful, often with grave systemic disturbance, and has, moreover, several centres of suppuration. #state the prognosis.# when occurring in crops (furunculosis) the affection is often rebellious; recovery, however, finally resulting. #what is the method of treatment of furunculus?# if there be but one lesion, with no tendency to the appearance of others, local treatment alone is usually employed. if, however, several or more are present, or if there is a tendency to successive development, both constitutional and local measures are demanded. #name the internal remedies employed.# such nutrients and tonics as cod-liver oil, malt, quinine, strychnia, iron and arsenic; in some instances calx sulphurata, one-tenthto one-fourth-grain doses every three or four hours has been thought to be of service. brewers' yeast has been recently again brought forward as a remedy of value. #what is the external treatment?# local treatment consists in the beginning, with the hope of aborting the lesion, of the application of carbolic acid to the central portion, or the use of a twenty-five-per-cent. ointment of ichthyol applied as a plaster:- [rx] ichthyol, ............................ [dram]j emp. plumbi, ........................... [dram]ij emp. resinæ, ........................... [dram]j. m. or the injection of a five-per-cent. solution of carbolic acid into the apex of the boil may be tried if the formation is more advanced. if suppuration is fully established, evacuation of the contents, followed by antiseptic applications, constitutes the best method. a saturated solution of boric acid or a lotion of corrosive sublimate (one to three grains to the ounce) applied to the immediate neighborhood of the boil or boils tends to prevent the formation of new lesions. frequent washing of the parts with soap and water or tincture of green soap and water is also a preventive measure of value. in repeatedly infected areas, mild exposures to _x_-rays, at intervals of a few days, will often prove of curative value. #carbunculus.# (_synonyms:_ anthrax; carbuncle.) #what is carbuncle?# a carbuncle is an acute, usually egg to palm-sized, circumscribed, phlegmonous inflammation of the skin and subcutaneous structures, terminating in a slough. #at what age and upon what parts is carbuncle usually observed?# in middle and advanced life, and more commonly in men. it is seen most frequently at the nape of the neck and upon the upper part of the back. #what are the symptoms and course of carbuncle?# there is rarely more than one lesion present. it begins, usually with preceding and accompanying malaise, chilliness and febrile disturbance, as a firm, flat, inflammatory infiltration in the deeper skin and subcutaneous tissue, spreading laterally and finally involving an area of one to several inches in diameter. the infiltration and swelling increase, the skin becomes of dark red color, and sooner or later, usually at the end of ten days or two weeks, softening and suppuration begin to take place, the skin finally giving away at several points, through which sanious pus exudes; the whole mass finally sloughs away either in portions or in its entirety, resulting in a deep ulcer, which slowly heals and leaves a permanent cicatrix. in some cases, especially in old people, constitutional disturbance of a grave character is noted, septicæmia is developed, and a fatal result may ensue. #what is the cause of carbuncle?# the same causes are considered to be operative in carbunculus as in furuncle; general debility and depression, from whatever cause, predisposing to its formation, and the introduction of a microbe, probably the same as in furunculus, being at present looked upon as the exciting factor. #what is the pathology?# the inflammation starts simultaneously from numerous points, from the hair-follicles, sweat-glands or sebaceous glands. the inflammatory centres break down, and the pus finds its way to the surface; finally the process ends in gangrene of the whole area. #how would you distinguish carbuncle from a boil?# by its flat character, greater size, and multiple points of suppuration. #what is the prognosis of carbuncle?# occurring in those greatly debilitated or in late life, and in those cases in which two or more lesions exist, or when seated about the head, the prognosis is always to be guarded, as a fatal result is not uncommon. in fact, in every instance the disease is to be considered of possible serious import. #what constitutional treatment is usually employed in carbuncle?# a full nutritious diet, the use of such remedies as iron, quinia, nux vomica, with malt and stimulants, if indicated. calx sulphurata, one-tenth to one-fourth grain every two or three hours, appears, in some instances, to have a beneficial effect. if the pain is severe, morphia or chloral should be given. #what external measures are employed?# in the early part of the formation, injection of a five or ten per cent. carbolic acid solution, or covering the whole area with a twenty-five per cent. ichthyol ointment, may be employed. when it has broken down the pus may be drawn out with a cupping-glass, and carbolized glycerine or carbolized water introduced into each opening, and the ichthyol ointment superimposed. if the whole part has sloughed, it should be removed as rapidly as possible, and antiseptic dressings used. or, if its progress is slow, and grave systemic disturbance be present, the whole part may be incised and curetted, and then treated antiseptically. mild exposure to the _x_-rays is also to be commended. #pustula maligna.# (_synonyms:_ anthrax; malignant pustule.) #what is malignant pustule?# malignant pustule is a furuncleor carbuncle-like lesion resulting from inoculation of the virus generated in animals suffering from splenic fever, or "charbon," and is accompanied by constitutional symptoms of more or less gravity. a fatal termination is not unusual. #what is the cause of pustula maligna?# the disease is due to the presence of the bacillus anthracis. #what is the treatment of malignant pustule?# early excision or destruction with caustic potash, with subsequent antiseptic dressings; and internally the free use of stimulants and tonics. #post-mortem pustule.# (_synonym:_ dissection wound.) #describe post-mortem pustule.# post-mortem pustule develops at the point of inoculation, beginning as an itchy red spot, becoming vesico-pustular, and later pustular, with usually a broad inflammatory base, and accompanied with more or less pain and redness and not infrequently lymphangitis, erysipelatous swelling, and slight or severe sympathetic constitutional disturbance. #what is the treatment of post-mortem pustule?# treatment consists in opening the pustule and thorough cauterization, and the subsequent use of antiseptic applications or dressings. _internally_ quinia and stimulants if indicated. #framb[oe]sia.# (_synonyms:_ yaws; pian.) #describe framb[oe]sia.# framb[oe]sia is an endemic, contagious disease met with in tropical countries, characterized by the appearance of variously-sized papules, tubercles, and tumors, which, when developed, resemble currants and small raspberries, and finally break down and ulcerate. it is accompanied by constitutional symptoms of variable severity. hygienic measures, good food, tonics, and antiseptic and stimulating applications are curative. #verruga peruana.# (_synonyms:_ peruvian warts; carrion's disease; oroya fever.) #describe verruga peruana.# a specific inoculable affection endemic in some valleys of the western andes, in peru, and characterized by a prodromal febrile period and subsequent outbreak of peculiar pin-headto pea-sized, or larger, bright reddish, rounded, wart-like elevations. the prodromal symptoms, of an irregular malarial or typhoid type, with associated rheumatic and muscular pains, may last for weeks or several months, usually abating when eruption presents. the lesions may be crowded together in great bunches. the face and limbs are favorite localities. the disease is inoculable and thought to be due to a bacillus. the fatality varies between 10 and 20 per cent. tonics and stimulants are prescribed. #equinia.# (_synonyms:_ farcy; glanders.) #what is equinia, or glanders?# a rare contagious specific disease of a malignant type, derived from the horse, and characterized by grave constitutional symptoms, inflammation of the nasal and respiratory passages, and a deep-seated papulo-pustular, or tubercular, nodular (_farcy buds_), ulcerative eruption. a fatal issue is not uncommon. it is due to a micro-organism. treatment, both local and constitutional, is based upon general principles. #miliaria.# (_synonyms:_ prickly heat; heat rash; lichen tropicus; red gum; strophulus.) #what do you understand by miliaria?# an acute mildly inflammatory disorder of the sweat-glands, characterized by the appearance of minute, discrete but closely crowded papules, vesico-papules, and vesicles. #describe the symptoms of miliaria.# the eruption, consisting of pin-point to millet-seed-sized papules, vesico-papules, vesicles, or a mixture of these lesions, discrete but usually numerous and closely crowded, appears suddenly, occurring upon a limited portion of the surface, or, as commonly observed, involving a greater part or the whole integument. the trunk is a favorite locality. the papular lesions are pinkish or reddish, and the vesicles whitish or yellowish, surrounded by inflammatory areola, thus giving the whole eruption a bright red appearance--_miliaria rubra_. later, the areolæ fade, the transparent contents of the vesicles become somewhat opaque and yellowish-white, and the eruption has a whitish or yellowish cast--_miliaria alba_. in long-continued cases, especially in children, boils and cutaneous abscesses sometimes develop; and it may also develop into a true eczema. itching, or a feeling of burning, slight or intense, is usually present. #what is the course of the eruption?# the vesicles show no disposition to rupture, but dry up in a few days or a week, disappearing by absorption and with slight subsequent desquamation; the papular lesions gradually fade away, and the affection, if the exciting cause has ceased to act, terminates. #what is the cause of miliaria?# excessive heat. debilitated individuals, especially children, are more prone to an attack. being too warmly clad is often causative. #what is the nature of the disease?# the affection is considered to be due to sweat-obstruction, with mild inflammatory symptoms as a cause or consequence, congestion and exudation taking place about the ducts, giving rise to papules or vesicles, according to the intensity of the process. #how would you distinguish miliaria from papular and vesicular eczema, and from sudamen?# the papules of eczema are larger, more elevated, firmer, slower in their evolution, of longer duration, and are markedly itchy. the vesicles of eczema are usually larger, tend to become confluent, and also to rupture and become crusted; there is marked itchiness, and the inflammatory action is usually severe and persistent. in sudamen there is absence of inflammatory symptoms. #what is the prognosis of miliaria?# the affection, under favorable circumstances, disappears in a few days or weeks. if the cause persists, as for instance, in infants or young children too warmly clad, it may result in eczema. #what is the treatment of miliaria?# removal of the cause, and in debilitated subjects the administration of tonics; together with the application of cooling and astringent lotions, as the following:- [rx] aeidi carbolici, ..................... [dram]ss-[dram]j acidi borici, ........................ [dram]iv glycerinæ, ........................... f[dram]j alcoholis, ........................... f[oz]ij aquæ, ................................ [oz]xiv. m. this is sometimes more efficient if zinc oxide, six to eight drachms, is added. lotions of alcohol and water or vinegar and water, and also the various lotions used in acute eczema, are often employed with relief. dusting-powders of starch, boric acid, lycopodium, talc, and zinc oxide are also valuable; the following combination is satisfactory:- [rx] pulv. acidi borici, pulv. talci veneti, pulv. zinci oxidi, pulv. amyli, .............[=a][=a].....[dram]ij. m. probably the best plan is to use a lotion and a dusting-powder conjointly; dabbing on the wash freely, allowing it to dry, and then dusting over with the powder. #pompholyx.# (_synonyms:_ dysidrosis; cheiro-pompholyx.) #what is pompholyx?# pompholyx is a rare disease of the skin of a vesicular and bullous character, and limited to the hands and feet. #describe the symptoms of pompholyx.# in most instances the hands only are affected. it begins usually with a feeling of burning, tingling or tenderness of the parts, followed rapidly by the appearance of deeply-seated vesicles, especially between the fingers and on the palmar aspect. these beginning lesions look not unlike sago grains imbedded in the skin. in some instances the disease does not extend beyond this stage, the vesicles disappearing after a few days or weeks by absorption, and usually without desquamation. ordinarily, however, the lesions increase in size, new ones arise, become confluent, and blebs result, the skin in places appearing as if undermined with serous exudation. the parts are commonly inflamed to a slight or marked degree. the skin comes off in flakes, new lesions may appear for several days or two or three weeks, and the process then declines, recovery gradually taking place. there are no constitutional symptoms, although it is usually noticed that the general health is below par. #what is the character of the subjective symptoms in pompholyx?# the subjective symptoms consist of a feeling of tension, burning and tenderness, and sometimes itching. not infrequently, also there is neuralgic pain. #what is the cause of pompholyx?# the eruption is thought to be due to a depressed state of the nervous system. it is more common in women, and is met with chiefly in adult and middle life. #what is the pathology?# opinion is divided; some considering it a disease of the sweat-glands and others an inflammatory disease independent of these structures. #state the diagnostic features of pompholyx.# the distribution and the peculiar characters and course of the eruption. it is to be differentiated from eczema. #what is the prognosis?# for the immediate attack, favorable, recovery taking place in several weeks or a few months. recurrences at irregular intervals are not uncommon. #what is the treatment of pompholyx?# the general health is to be looked after, and the patient placed under good hygienic conditions. remedies of a tonic nature, directed especially toward improving the state of the nervous system, are to be prescribed. _locally_, soothing and anodyne applications, such as lead-water and laudanum, boric-acid lotion, oxide-of-zinc, boric-acid and diachylon ointments, are most suitable; or the parts may be enveloped with the following:- [rx] pulv. ac. salicylici, ................ gr. x pulv. ac. borici, pulv. amyli, .......... [=a][=a] ..... [dram]ij petrolati, ........................... [dram]iv. m. in fact, the external treatment is similar to that employed in acute eczema. #herpes simplex.# (_synonym:_ fever blisters.) #what is herpes simplex?# an acute inflammatory disease, characterized by the formation of pin-head to pea-sized vesicles, arranged in groups, and occurring for the most part about the face and genitalia. #describe the symptoms of herpes simplex.# in severe cases, malaise and pyrexia may precede the eruption, but usually it appears without any precursory or constitutional symptoms. a feeling of heat and burning in the parts is often complained of. the vesicles, which are commonly pin-head in size, are usually upon a hyperæmic or inflammatory base, and tend to occur in groups or clusters. their contents are usually clear, subsequently becoming more or less milky or puriform. there is no tendency to spontaneous rupture, but should they be broken a superficial excoriation results. in a short time they dry to crusts which soon fall off, leaving no permanent trace. #is the eruption in herpes simplex abundant?# no. as a rule not more than one or two clusters or groups are observed. #upon what parts does the eruption occur?# usually about the face (_herpes facialis_), and most frequently about the lips (_herpes labialis_); on the genitalia (_herpes progenitalis_), the lesions are commonly found on the prepuce (_herpes præputialis_) in the male, and on the labia minora and labia majora in the female. #state the causes of herpes simplex.# herpes facialis is often observed in association with colds and febrile and lung diseases. malaria, digestive disturbance, and nervous disorders are not infrequently predisposing factors. herpes progenitalis is said to occur more frequently in those who have previously had some venereal disease, especially gonorrh[oe]a, but this is questionable. it is probably often purely neurotic. #what are the diagnostic points?# the appearance of one or several vesicular groups or clusters about the face, and especially about the lips, is usually sufficiently characteristic. the same holds true ordinarily when the eruption is seen on the prepuce or other parts of the genitalia; it is only when the vesicles become rubbed or abraded and irritated that it might be mistaken for a venereal sore, but the history, course and duration will usually serve to differentiate. #give the prognosis.# the eruption will usually disappear in several days or one or two weeks without treatment. remedial applications, however, exert a favorable influence. herpes progenitalis exhibits a strong disposition to recurrence. #what is the treatment of herpes facialis?# anointing the parts with camphorated cold cream, with spirits of camphor or similar evaporating and stimulating applications will at times afford relief to the burning, and shorten the course. #what is the treatment of herpes progenitalis?# in herpes about the genitalia cleanliness is of first importance. a saturated solution of boric acid, a dusting-powder of calomel or oxide of zinc, and the following lotion, containing calamine and oxide of zinc, are valuable:- [rx] zinci oxidi, calaminæ, .......... [=a][=a] ........ gr. v glycerinæ, alcoholis, ......... [=a][=a] ........ [minim]vj aquæ, ................................ [oz]j m. in obstinate recurrent cases, frequent applications of a mild galvanic current will have a favorable influence. #hydroa vacciniforme.# (_synonyms:_ recurrent summer eruption; hydroa puerorum; hydroa aestivale.) #describe hydroa vacciniforme.# it is a rare vesicular disease usually seen in boys (only two or three exceptions), occurring upon uncovered parts, especially the nose, cheeks, and ears. the lesions begin as red spots, discrete or in groups, rapidly exhibit vesiculation, and later umbilication; the contents become milky, dry to crusts, which fall off and leave small pit-like scars. fresh outbreaks may take place almost continuously, and the process go on indefinitely, at least up to youth or manhood, when the tendency subsides. its activity is usually limited to the warm season. arthritic symptoms and general disturbance are sometimes noted in severe cases. it is doubtless a vasomotor neurosis. exposure to sun and wind is an important, if not essential, etiological factor. primarily the lesion begins in the rete middle layers, and is purely vesicular in character; later, necrosis of the rete and extending deep in the corium is observed. treatment so far has only been palliative, consisting of the applications employed in similar conditions. constitutional medication is based upon general principles. the patient should avoid exposure to the sun, strong wind and excessive artificial heat. #epidermolysis bullosa.# #describe epidermolysis bullosa.# this is a rare, usually hereditary, disease or condition, characterized by the formation of vesicles and blebs on any part subjected to slight rubbing or irritation. no scarring is left, and no pigmentation noted. the predisposition to these lesions persists indefinitely. the general health is not involved. the nature of the disease is obscure. treatment has no influence in modifying or lessening this tendency. the vulnerable parts should so far as possible be protected from knocks and undue friction. #dermatitis repens.# #what do you understand by dermatitis repens?# it is a rare spreading dermatitis starting from an injury, extending by a serous undermining of the epidermis, and usually occurring upon the upper extremities. it usually begins shortly after an injury, and, as a rule, presents itself by redness and serous exudation. the overlying epidermis breaks, and the area of disease gradually progresses by an extension of the serous undermining process, the denuded part looking red and raw, with usually an oozing surface. as the disease spreads the oldest part becomes dry and heals, the new epidermal covering being thin and atrophic in appearance. its most usual beginning is on some part of the hand, and from here it may spread up the arm and involve considerable area. the injury from which it starts may be extremely insignificant, apparently affording an opening for the introduction of the causative factor, doubtless parasitic. beyond a feeling of soreness there seem to be no special subjective symptoms. #give the prognosis and treatment.# the malady shows but little tendency to spontaneous cure. the frequent or constant application of a mild antiseptic lotion, such as boric acid and resorcin, or of a mild parasiticide ointment will generally bring the disease gradually to an end. #herpes zoster.# (_synonyms:_ zoster; zona; shingles.) #give a definition of herpes zoster.# herpes zoster is an acute, self-limited, inflammatory disease, characterized by groups of vesicles upon inflammatory bases, situated over or along a nerve tract. #upon what parts of the body may the eruption appear?# it may appear upon any part, following the course of a nerve; it is therefore always limited in extent, and confined to one side of the body. it is probably most common about the intercostal, lumbar and supra-orbital regions. in rare instances the eruption has been observed to be bilateral. #are there any subjective or constitutional symptoms?# yes; there is, as a rule, neuralgic pain preceding, during and following the eruption; and in some cases, also, there may be in the beginning mild febrile disturbance. there is also a variable degree of tenderness and pain. #what are the characters of the eruption?# several or more hyperæmic or inflammatory patches over a nerve course appear, upon which are seated vesico-papules irregularly grouped; these vesico-papules become distinct vesicles, of size from a pin-head to a pea, and soon dry and give rise to thin, yellowish or brownish crusts, which drop off, leaving in most instances no permanent trace, in others more or less scarring. in some cases the lesions may become pustular and, on the other hand, the eruption may be abortive, stopping short of full vesiculation. #what is known in regard to the nature of the disease?# an inflamed and irritable state of the spinal ganglia, nerve tract, or peripheral branches is directly responsible for the eruption, and this state may be due to atmospheric changes, cold, nerve-injuries and similar influences. the view has also been advanced that the disease is of specific and infectious character. #give the chief diagnostic features of herpes zoster.# the prodromic neuralgic pain, the appearance of grouped vesicles upon inflammatory bases following the course of a nerve tract, and the limitation of the eruption to one side of the body. #what is the prognosis?# favorable; the symptoms usually disappearing in two to four weeks. in some instances, however, the neuralgic pains may be persistent, and in zoster of the supra-orbital region the eye may suffer permanent damage. #how would you treat herpes zoster?# _constitutional treatment_, usually tonic in character, is to be based upon general principles; moderate doses of quinia, with one-sixth grain of zinc phosphide, four or five times daily, appear in some cases to have a special value. the accompanying neuralgic pain may be so intense as to require anodynes. _local treatment_ should be of a soothing and protective character. a dusting-powder of oxide of zinc and starch (to the ounce of which twenty to thirty grains of camphor may be added) proves useful; and over this, in order that the parts be further protected, a bandage or a layer of cotton batting. oxide-of-zinc ointment, and in those cases in which there is much pain, ointments containing powdered opium or belladonna, or orthoform, may be used. a mild galvanic current applied daily to the parts is often of great advantage, both in its influence upon the course of the eruption and upon the neuralgic pain. the plan, so often advised, of painting the parts with flexible collodion is not to be commended. #dermatitis herpetiformis.# (_synonyms:_ hydroa herpetiforme (tilbury fox); herpes gestationis (bulkley); pemphigus prurigiuosus; duhring's disease.) #give a definition of dermatitis herpetiformis.# dermatitis herpetiformis is a somewhat rare inflammatory disease, characterized by an eruption of an erythematous, papular, vesicular, pustular, bullous or mixed type, with a decided disposition toward grouping, accompanied by itching and burning sensations, with, as a rule, more or less consequent pigmentation, and pursuing usually a chronic course with remissions. #describe the erythematous type of dermatitis herpetiformis.# the character of the eruption in the erythematous type resembles closely that of erythema multiforme and of urticaria, especially the former. the efflorescences usually make their appearance in crops, and are more or less persistent; fading sooner or later, however, and giving place to new outbreaks. vesicles are often intermingled, developing from erythematous and erythemato-papular lesions or arising from apparently normal skin. it may continue in the same type, or change to the vesicular, bullous or other variety. #describe the papular type of dermatitis herpetiformis.# this is rarely seen as consisting purely of papular lesions, but is commonly associated with the erythematous and vesicular varieties. in a measure it resembles the papular manifestations of erythema multiforme, with a distinct disposition toward group formation. the papules tend, sooner or later, to develop into vesicles, new papular outbreaks occurring from time to time; or the whole eruption changes to the vesicular or other type of the disease. it is not a common type. #describe the vesicular type of dermatitis herpetiformis.# this is the common clinical type of the disease, and is characterized by pin-head to pea-sized, rounded or irregularly-shaped, distended or flattened and stellate vesicles, occurring, for the most part, in irregular and segmental groups of three or more lesions, seated either upon apparently normal integument or upon hyperæmic or inflammatory skin. they exhibit no tendency to spontaneous rupture, but after remaining a shorter or longer time, are broken or disappear by absorption. the lesions tend to appear in crops. it may, as it not infrequently does, continue in the same type, or it may become more or less erythematous or bullous in character. in not a few instances pustules, few or in numbers, are at times intermingled. #describe the pustular type of dermatitis herpetiformis.# this is rare. it is similar in its clinical characters to the vesicular type, except that the lesions are pustular. it is met with, as a rule, in association with the vesicular and bullous varieties of the disease. #describe the bullous type of dermatitis herpetiformis.# the bullous expression of the disease is usually of a markedly inflammatory nature, often innumerable blebs, small and large, appearing almost continuously, and in some instances involving the greater part of the surface. the lesions arise from erythematous skin, from preëxisting vesicles or vesicular groups, or from apparently normal integument. there is a marked disposition to appear in clusters. a change of type to the erythematous or vesicular varieties is not unusual. #describe the mixed type of dermatitis herpetiformis.# in this type the eruption is made up of erythematous patches, vesicles, bullæ, and often with pustules intermingled, appearing irregularly or in crops, and with a tendency to patch or group formation. #describe the characters of the vesicles, pustules and blebs.# as a rule, these several lesions, especially the vesicles and blebs, are somewhat peculiar: they are usually of a strikingly irregular outline, oblong, stellate, quadrate, and when drying are apt to have a puckered appearance. they are herpetic in that they show little disposition to spontaneous rupture, occur in groups, and are usually seated upon erythematous or inflammatory skin--in some respects similar to the groups of simple herpes and herpes zoster. #what is to be said in regard to the subjective symptoms?# the subjective symptoms are usually the most troublesome feature of the disease, consisting of intense and persistent itching and a feeling of heat and burning. #are there any constitutional symptoms in dermatitis herpetiformis?# as a rule, not, excepting the distress and depression necessarily consequent upon the intense itchiness and loss of sleep. in the pustular and bullous varieties there may be mild or grave systemic symptoms, but even in these types the constitutional involvement is, in most instances, slight in comparison to the intensity of the cutaneous disturbance. #what is the course of dermatitis herpetiformis?# extremely chronic, in most instances lasting, with remissions, indefinitely. the skin is rarely entirely free. from time to time the type of the disease may undergo change. from the continued irritation and scratching more or less pigmentation results. #what is to be said in regard to the etiology?# the disease is in many instances essentially neurotic, and in exceptional instances septicæmic. pregnancy and the parturient state are factors in some instances (so-called herpes gestationis). it is possible in some instances that the eruption may be an expression of a mild toxemia of gastro-intestinal origin. in some cases no cause can be assigned. in the majority of patients the general health, considering the violence of the eruptive phenomena, remains comparatively undisturbed. nervous shock and mental worry are factors in some cases. polyuria, with sugar in the urine, has occasionally been noted. eosinophile cells have been found both in the vesicles and the blood. in some instances--exceptionally, it is true--the disease has appeared shortly after vaccination. #mention the diagnostic features of dermatitis herpetiformis.# the multiformity of the eruption, the characters of the lesions, the disposition to grouping, the absence of tendency to form solid sheets of eruption (as in eczema), the intense itching, history, chronicity and course. in doubtful cases, an observation of several weeks will always suffice to distinguish it from eczema, erythema multiforme, herpes iris and pemphigus, diseases to which it at times bears strong resemblance. #give the prognosis of dermatitis herpetiformis.# an opinion as to the outcome of the disease should be guarded. it is exceedingly rebellious to treatment, and relapses are the rule. exceptionally the bullous and pustular varieties prove eventually fatal. the erythematous and vesicular varieties are the most favorable. #state the treatment to be advised.# there are no special remedies. constitutional treatment must be conducted upon general principles. a free action of the bowels is to be maintained. in occasional instances arsenic in progressive doses seems of value. externally protective and antipruritic applications, such as are employed in the treatment of eczema and pemphigus, are to be employed:- [rx] ac. carbolici, ....................... [dram]j-[dram]ij thymol, .............................. gr. xvj. glycerinæ, ........................... [oz]ss-[oz]j alcoholis, ........................... f[oz]ij aquæ, q.s., ......... ad ............. oj. m. other valuable applications are: lotions of carbolic acid, of liquor carbonis detergens, of boric acid; alkaline baths, mild sulphur ointment and carbolized oxide-of-zinc ointment, and dusting-powders of starch, zinc oxide, talc and boric acid. a twoto ten-per-cent. ichthyol lotion or ointment is sometimes of advantage; thiol employed in the same manner has also been commended. #psoriasis.# #give a definition of psoriasis.# psoriasis is a chronic, inflammatory disease, characterized by dry, reddish, variously-sized, rounded, sharply-defined, more or less infiltrated, scaly patches. [illustration: psoriasis.] #at what age does psoriasis usually first make its appearance?# most commonly between the ages of fifteen and thirty. it is rarely seen before the tenth year, and a first attack is uncommon after the age of forty. #has psoriasis any special parts of predilection?# the extensor surfaces of the limbs, especially the elbows and knees, are favorite localities, and even when the eruption is more or less general, these regions are usually most conspicuously involved. the face often escapes, and the palms and soles, likewise the nails, are rarely involved. in exceptional instances, the eruption is limited almost exclusively to the scalp. #are there any constitutional or subjective symptoms in psoriasis?# there is no systemic disturbance; but a variable amount of itching may be present, although, as a rule, it is not a troublesome symptom. #describe the clinical appearances of a typical, well developed case.# twenty or a hundred or more lesions, varying in size from a pin-head to a silver dollar, are usually present. they are sharply defined against the sound skin, are reddish, slightly elevated and infiltrated, and more or less abundantly covered with whitish, grayish or mother-of-pearl colored scales. the patches are usually scattered over the general surface, but are frequently more numerous on the extensor surfaces of the arms and legs, especially about the elbows and knees. several closely-lying lesions may coalesce and a large, irregular patch be formed; some of the patches, also, may be more or less circinate, the central portion having, in a measure or completely, disappeared. #give the development and history of a single lesion.# every single patch of psoriasis begins as a pin-point or pin-head-sized, hyperæmic, scaly, slightly-elevated lesion; it increases gradually, and in the course of several days or weeks usually reaches the size of a dime or larger, and then may remain stationary; or involution begins to take place, usually by a disappearance, partially or completely, of the central portion, and finally of the whole patch. #describe the so-called clinical varieties of psoriasis.# as clinically met with, the patches present are, as a rule, in all stages of development. in some instances, however, the lesions, or the most of them, progress no further than pin-head in size, and then remain stationary, constituting _psoriasis punctata_; in other cases, they may stop short after having reached the size of drops--_psoriasis guttata_; in others (and this is the usual clinical type) the patches develop to the size of coins--_psoriasis nummularis_. in some cases there is a strong tendency for the central part of the lesions to disappear, and the process then remain stationary, the patches being ring-shaped--_psoriasis circinata_; and occasionally several such rings coalesce, the coalescing portions disappearing and the eruption be more or less serpentine--_psoriasis gyrata_. or, in other instances, several large contiguous lesions may coalesce and a diffused, infiltrated patch covering considerable surface results--_psoriasis diffusa, psoriasis inveterata_. [illustration: fig. 17. psoriasis.] #is the eruption of psoriasis always dry?# yes. #what course does psoriasis pursue?# as a rule, eminently chronic. patches may remain almost indefinitely, or may gradually disappear and new lesions appear elsewhere, and so the disease may continue for months and, sometimes, for years; or, after continuing for a longer or shorter period, may subside and the skin remain free for several months or one or two years, and, in rare instances, may never return. [illustration: fig. 18. psoriasis.] #is the course of psoriasis influenced by the seasons?# as a rule, yes; there is a natural tendency for the disease to become less active or to disappear altogether during the warm months. #what is known in regard to the etiology of psoriasis?# the causes of the disease are always more or less obscure. there is often a hereditary tendency, and the gouty and rheumatic diathesis must occasionally be considered potential. in some instances it is apparently influenced by the state of the general health. it is a rather common disease and is met with in all walks of life. #is psoriasis contagious?# no. in recent years the fact of its exhibiting a family tendency has been thought as much suggestive of contagiousness as of heredity. #what is the pathology?# according to modern investigations, it is an inflammation induced by hyperplasia of the rete mucosum; and it is beginning to be believed that this hyperplasia may have a parasitic factor as the starting-cause. #with what diseases are you likely to confound psoriasis?# chiefly with squamous eczema and the papulo-squamous syphiloderm; and on the scalp, also with seborrh[oe]a. it can scarcely be confounded with ringworm. #how is psoriasis to be distinguished from squamous eczema?# by the sharply-defined, circumscribed, scattered, scaly patches, and by the history and course of the individual lesions. #in what respects does the papulo-squamous syphiloderm differ from psoriasis?# the scales of the squamous syphilide are usually dirty gray in color and more or less scanty; the patches are coppery in hue, and usually several or more characteristic scaleless, infiltrated papules are to be found. the face, palms, and soles are often the seat of the syphilitic eruption; and, moreover, _concomitant symptoms of syphilis_, such as sore throat, mucous patches, glandular enlargement, rheumatic pains, falling out of the hair, together with the history of the initial lesion, are one, several, or all usually present. #how does seborrh[oe]a differ from psoriasis?# seborrh[oe]a of the scalp is usually diffused, with but little redness and no infiltration; moreover, the scales of seborrh[oe]a are greasy, dirty gray or brownish, while those of psoriasis are dry and comonly whitish or mother-of-pearl colored. psoriasis of the scalp rarely exists independently of other patches elsewhere on the general surface. that variety of seborrh[oe]a, commonly known as eczema seborrhoicum, presents at times, both on scalp and general surface, a strong resemblance to psoriasis, but the character of the scales and distribution of psoriasis, as above stated, are distinguishing points; seborrh[oe]a, moreover, favors hairy surfaces and in extensive examples the scalp, eyebrows, sternal, and pubic regions rarely escape. #how does psoriasis differ from ringworm?# by its greater scaliness, by its higher degree of inflammatory action, and by its larger number of patches, as also by its history. in ringworm _all_ the patches tend to clear up in the centre; in psoriasis this is rarely, if ever, so. if there is still any doubt, microscopic examination of the scrapings will determine. #give the prognosis of psoriasis.# the prognosis is usually favorable, so far as concerns the immediate eruption, but as to recurrences, nothing positive can be stated. in rare instances, however, the cure remains permanent. #how is psoriasis treated?# both constitutional and local remedies are demanded in most cases. #do dietary measures exert any influence?# as a rule, no; but the food should be plain, and an excess of meat avoided. #name the important constitutional remedies usually employed in psoriasis.# _arsenic_ is of first importance. it is not suitable in acute or markedly inflammatory types; but is most useful in the sluggish, chronic forms of the disease. the dose should never be pushed beyond slight physiological action. it may be given as arsenious acid in pill form, one-fiftieth to one-tenth of a grain three times daily, or as fowler's solution, three to ten minims at a dose. _alkalies_, of which liquor potassæ is the most eligible. it is to be given in ten to twenty minim doses, largely diluted. it is valuable in robust, plethoric, rheumatic or gouty individuals with psoriasis of an acute or markedly inflammatory type; it is not to be given to debilitated or anæmic subjects. _salicin_, sodium salicylate, and salophen in moderately full doses act well in some cases. occasionally thyroid preparations have a good effect. _potassium iodide_, in doses of thirty to one hundred grains, t.d., acts favorably in some instances; there are no special indications pointing toward its selection, unless it be the existence of a gouty or rheumatic diathesis. oil of copaiba, potassium acetate, oil of turpentine, oil of juniper, and other diuretics are valuable in some instances, and, while often failing, sometimes exert a rapid influence, especially in those cases in which the disease is extensive and inflammatory. wine of antimony, given cautiously, is also sometimes of service in the acute inflammatory type in robust subjects. #are such remedies as iron, quinine, nux vomica and cod-liver oil ever useful in psoriasis?# yes. in debilitated subjects the administration of such remedies is at times attended with improvement in the cutaneous eruption. #what are the indications as regards the external measures?# removal of the scales, and the use of soothing or stimulating applications, according to the individual case. #how are the scales removed?# in ordinary cases, either by warm, plain, or alkaline baths, or hot-water-and-soap washings; in those cases in which the scaling is abundant and adherent, washing with sapo viridis and hot water may be required. baths of sal ammoniac, two to six ounces to the bath are also valuable in removing the scaliness. the tincture of green soap (tinctura saponis viridis) is especially valuable for cleansing purposes in psoriasis of the scalp. the hot vapor bath once or twice weekly is serviceable in keeping the scaliness in abeyance, and has, moreover, in some cases, a therapeutic value. the frequency of the baths or washings will depend upon the rapidity with which the scales are reproduced. #are soothing applications often demanded in psoriasis?# in exceptional cases; in those in which the disease is acute, markedly inflammatory and rapidly progressing, mild, soothing applications must be temporarily employed, such as plain or bran baths, with the use of some bland oil or ointment. as a rule, however, the conditions, when coming under observation, are such as to permit of stimulating applications from the start. the most efficient soothing applications are the mild lotions and ointments employed in eczema of acute type. #how are the stimulating remedies employed in psoriasis applied?# as ointments, oils, and paints (pigmenta). an ointment, if employed, is to be thoroughly rubbed in the diseased areas once or twice daily. the same may be said of the oily applications. the paints (medicated collodion and gutta-percha solution) are applied with a brush, once daily, or every second or third day, depending mainly upon the length of time the film remains intact and adherent. #name the several important external remedies.# chrysarobin, pyrogallol, tar, ammoniated mercury, [beta]-naphthol, and resorcin. #are these several external remedies equally serviceable in all cases?# no. their action differs slightly or greatly according to the case and individual. a change from one to another is often necessary. #in what forms and strength are these remedies to be applied?# _chrysarobin_ is applied in several ways: as an ointment, twenty to sixty grains to the ounce, rubbed in once or twice daily; this is the most rapid but least cleanly and eligible method. as a pigment, or paint, as in the following:- [rx] chrysarobini, ........................ [dram]j acidi salicylici, .................... gr. xx etheris, ............................. f[dram]j ol. ricini, .......................... [minim]x collodii, ............................ f[dram]vij. m. or it may be used in liquor gutta-perchæ (traumaticin), a drachm to the ounce. it may also be employed in chloroform, a drachm to the ounce; this is painted on, the chloroform evaporating, leaving a thin film of chrysarobin; over this is painted flexible collodion. if the patches are few and large, chrysarobin rubber-plaster may be used. chrysarobin is usually rapid in its effect, but it has certain disadvantages; it may cause an inflammation of the surrounding skin, and, if used near the eyes, may give rise to conjunctivitis. as a rule, it should not be employed about the head. moreover, it stains the linen permanently and the skin temporarily. _pyrogallol_ is valuable, and is employed in the same manner and strength as chrysarobin. in collodion it should at first not be used of greater strength than three to four per cent., as in this form pyrogallol sometimes acts with unexpected energy. it is less rapid than chrysarobin, but it rarely inflames the surrounding integument. it stains the linen a light brown, however, and is not to be used over an extensive surface for fear of absorption and toxic effect. oxidized pyrogallic acid, a somewhat milder drug in its effect, has been highly commended, and has the alleged advantage of being free from toxic action. _tar_ is, all things considered, the most important external remedy. it is comparatively slow in its action, but is useful in almost all cases. as employed usually it is prescribed in ointment form, either as the official tar ointment, full strength or weakened with lard or petrolatum. it may also be used as pix liquida, with equal part of alcohol. or the tar oils, oil of cade (ol. cadini), and oil of birch (ol. rusci) may be employed, either as oily applications or incorporated with ointment or with alcohol. liquor carbonis detergens, in ointment, one to three drachms to the ounce of simple cerate and lanolin is a mild tarry application which is often useful. in stubborn patches an occasional thorough rubbing with a mixture of equal parts of liquor carbonis detergens and vleminckx's solution, followed by a mild ointment, sometimes proves of value. in whatsoever form tar is employed it should be thoroughly rubbed in, once or twice daily, the excess wiped off, and the parts then dusted with starch or similar powder. _ammoniated mercury_ is applied in ointment form, twenty to sixty grains to the ounce. compared to other remedies it is clean and free from staining, although, as a rule, not so uniformly efficacious. it is especially useful for application to the scalp and exposed parts. it should not be used over extensive surface for fear of absorption. _[beta]-naphthol_ and _resorcin_ are applied as ointments, thirty to sixty grains to the ounce, and as they are (especially the former) practically free from staining, may be used for exposed surfaces. gallacetophenone and aristol also act well in some cases, applied in fiveto ten-per-cent. strength, as ointments. in obstinate patches the _x_-ray may be resorted to, employing it with caution and in the same manner as in other diseases. #pityriasis rosea.# (_synonym:_ pityriasis maculata et circinata.) #what do you understand by pityriasis rosea?# pityriasis rosea is a disease of a mildly inflammatory nature, characterized by discrete, and later frequently confluent, variously sized, slightly raised scaly macules of a pinkish to rosy-red, often salmon-tinged, color. #upon what part of the body is the eruption usually found?# the trunk is the chief seat of the eruption, although not infrequently it is more or less general. #describe the symptoms of pityriasis rosea.# the lesions, which appear rapidly or slowly, are but slightly elevated, somewhat scaly, usually rounded, except when several coalesce, when an irregularly outlined patch results. at first they are pale or bright pink or reddish, later a salmon tint (which is often characteristic) is noticed. the scaliness is bran-like or flaky, of a dirty gray color, and, as a rule, less marked in the central portion; it is never abundant. the skin is rarely thickened, the process being usually exceedingly superficial. #what course does pityriasis rosea pursue?# the eruption makes its appearance, as a rule, somewhat rapidly, usually attaining its full development in the course of one or two weeks, and then begins gradually to decline, the whole process occupying one or two months. #to what is pityriasis rosea to be attributed?# the cause is not known; it is variously considered as allied to seborrh[oe]a (eczema seborrhoicum), as being of a vegetable-parasitic origin, and as a mildly inflammatory affection somewhat similar to psoriasis. it is not a frequent disease. #how is pityriasis rosea distinguished from ringworm, psoriasis and the squamous syphiloderm?# from ringworm, by its rapid appearance, its distribution, the number of patches, and, if necessary, by microscopic examination of the scrapings. psoriasis is a more inflammatory disease, is seen usually more abundantly upon the limbs, the scales are profuse and silvery, and the underlying skin is red and has a glazed look; moreover, psoriasis, as a rule, appears slowly and runs a chronic course. the squamous syphiloderm differs in its history, distribution, and above all, by the presence of concomitant symptoms of syphilis, such as glandular enlargement, sore throat, mucous patches, rheumatic pains, and falling out of the hair. #state the prognosis of pityriasis rosea.# it is favorable, the disease tending to spontaneous disappearance, usually in the course of several weeks or one or two months. #what treatment is to be advised in pityriasis rosea?# laxatives and intestinal antiseptics, and ointments of salicylic acid (5-15 grains to the ounce), of sulphur (10-40 grains to the ounce); or a compound ointment containing both these ingredients can be prescribed. the ointment base can be equal parts of white vaselin and cold cream; in some instances lassar's paste (starch powder, zinc oxid powder, each, [dram]ij; vaselin, [dram]iv) seems more satisfactory. #dermatitis exfoliativa.# (_synonyms:_ general exfoliative dermatitis; recurrent exfoliative dermatitis; desquamative scarlatiniform erythema; acute general dermatitis; recurrent exfoliative erythema; pityriasis rubra.) #describe dermatitis exfoliativa.# dermatitis exfoliativa is an inflammatory disease of an acute type, characterized by a more or less general erythematous inflammation, in exceptional instances vesicular or bullous, with epidermic desquamation or exfoliation accompanying or following its development. constitutional disturbance, which may be of a serious character, is sometimes present. it is a rare and obscure affection, running its course usually in several weeks or months, but exhibiting a decided tendency to relapse and recurrence. in many cases it is persistently chronic, with exacerbations and remissions. in some instances it develops from a long-continued and more or less generalized eczema or psoriasis, and in exceptional cases it is started by the careless use of mercurial ointment and of chrysarobin ointment. [illustration: fig. 19. dermatitis exfoliativa.] in another type of the disease, formerly described as _pityriasis rubra_, the skin is pale red or violaceous-red, but is rarely thickened, continued exfoliation in the form of thin plates taking place. its course is variable, lasting for years, with remissions. an exfoliating generalized dermatitis is exceptionally observed in the first weeks of life (_dermatitis exfoliativa neonatorum_), lasting some weeks, and in most cases followed by recovery. there are no special constitutional symptoms, the fatal cases usually dying of marasmus. as will be seen dermatitis exfoliativa varies considerably in degree; it may be extremely mild, resembling in appearance the scarlet-fever eruption (erythema scarlatiniforme) and running a rapid course; or the skin-condition and the systemic symptoms may be of grave and persistent character. #give the treatment of dermatitis exfoliativa.# general treatment is based upon indications, and externally soothing applications, such as are employed in acute and subacute eczema, are to be used. #lichen planus.# #what is lichen planus?# lichen planus is an inflammatory disease characterized by small, flat and angular, smooth and shining, or scaly, discrete or confluent, red or violaceous-red papules, having a distinctly papular or papulo-squamous course, and attended with more or less itching. #describe the symptoms of lichen planus.# the eruption, as a rule, begins slowly, usually showing itself upon the extremities; the forearms, wrists and legs being favorite localities. it may appear as one or more groups or in the form of short or long bands. occasionally its evolution is rapid and a considerable part of the surface may be invaded. the lesions are pin-head to small pea-sized, irregularly grouped or so closely crowded together as to form solid patches; they are quadrangular or polygonal in shape, usually flat, with central depression or umbilication, and are reddish or violaceous in color. at first they have a glazed or shining appearance; later, becoming slightly scaly, the scaliness being more marked where solid patches have resulted. new papules may appear from time to time, the older lesions disappearing and leaving persistent reddish or brownish pigmentation. exceptionally the eruption presents in bands or lines, like rows of beads (_lichen moniliformis_). very exceptionally a vesicular or bleb tendency in some of the lesions has been noted; doubtless, in most instances at least, this has been due to the arsenic so generally administered in this disease. in rare instances lichen planus lesions are also seen on the glans penis and on the buccal mucous membrane. in some cases, especially in the region of the ankle, the papules become quite large (_lichen planus hypertrophicus_), and in occasional cases there is a tendency in some of the lesions or patches to clear up centrally. there is, as a rule, considerable itching. there are no constitutional symptoms. #what is the etiology of lichen planus?# in some cases the disease is distinctly neurotic in character, in others no cause can be assigned. it is more especially met with at middle age, and among the wealthier, professional, and luxurious classes. pathologically the first change noted in the epidermis is thought to be an acanthosis, followed by epithelial atrophy, and a hyperkeratosis, intercellular edema, and colloid degeneration of the prickle cells. #does the disease bear any resemblance to the miliary papular syphilide, psoriasis, and papular eczema?# in some instances it does, but the irregular and angular outline, the slightly-umbilicated, flattened, smooth or scaly summits, and the dull-red or violaceous color, the history and course, of lichen planus, will serve to differentiate. #state the prognosis.# under proper management the eruption, although often obstinate, yields to treatment. #what treatment would you prescribe in lichen planus?# a general tonic plan of medication is indicated in most cases, with such remedies as iron, quinine, nux vomica, and cod-liver oil and other nutrients. in many instances arsenic exerts a special influence, and should always be tried. mercurials in moderate dosage have also a favorable action in most cases. locally, antipruritic and stimulating applications, such as are used in the treatment of eczema, are to be employed, alkaline baths and tarry applications deserving special mention. liquor carbonis detergens, applied weakened with several parts water, is a valuable application. in some cases, particularly if the disease is limited, external applications alone often suffice to bring about a cure. #pityriasis rubra pilaris.# (_synonyms:_ lichen ruber; lichen ruber acuminatus.) #describe pityriasis rubra pilaris.# pityriasis rubra pilaris is an extremely rare disease, usually of a mildly inflammatory nature, characterized by grayish, pale-red or reddish-brown follicular papules with somewhat hard or horny centres; discrete and confluent, and covering a part or the entire surface. the skin is harsh, dry and rough, feeling to the touch somewhat like the surface of a nutmeg-grater or a coarse file. more or less scaliness is usually present in the confluent patches and on the palms and soles; in these latter regions the papules are rarely seen. the duration of the disease is variable, and relapses are common. it bears resemblance at times to keratosis pilaris, ichthyosis, dermatitis exfoliativa; it is considered identical with the lichen ruber acuminatus of kaposi, and by many also with the lichen ruber of hebra. the etiology is obscure. treatment, both constitutional and local, is to be based upon general principles; stimulating applications, with frequent baths, such as are advised in psoriasis, are the most satisfactory. it is rebellious, and not much more than palliation can be effected in some cases, in others the outlook is more hopeful. #lichen scrofulosus.# #describe lichen scrofulosus.# lichen scrofulosus is a chronic, inflammatory disease, characterized by millet-seed-sized, rounded or flat, reddish or yellowish, more or less grouped, desquamating papules. the lesions have their start about the hair-follicles, occur usually upon the trunk, tend to group and form patches, and sooner or later become covered with minute scales. as a rule, there is no itching. it is a rare disease, and but seldom met with in america; it is seen chiefly in children and young people of a scrofulous diathesis. scarring, slight in character, may or may not follow. #what is the treatment of lichen scrofulosus?# the condition responds to tonics and anti-strumous remedies. #eczema.# (_synonym:_ tetter; salt rheum.) #what is eczema?# an acute, subacute or chronic inflammatory disease, characterized in the beginning by the appearance of erythema, papules, vesicles or pustules, or a combination of these lesions, with a variable amount of infiltration and thickening, terminating either in discharge with the formation of crusts, in absorption, or in desquamation, and accompanied by more or less intense itching and a feeling of heat or burning. #what are the several primary types of eczema?# erythematous, papular, vesicular and pustular; all cases begin as one or more of these types, but not infrequently lose these characters and develop into the common clinical or secondary types--eczema rubrum and eczema squamosum. [illustration: fig. 20. papular eczema (leg).] #what other types are met with clinically?# eczema rubrum, eczema squamosum, eczema fissum, eczema sclerosum and eczema verrucosum. eczema seborrhoicum is probably a closely allied disease, occupying a middle position between ordinary eczema and seborrh[oe]a. #describe the symptoms of erythematous eczema.# erythematous eczema (_eczema erythematosum_) begins as one or more small or large, irregularly outlined hyperæmic macules or patches, with or without slight or marked swelling, and with more or less itching or burning. at first it may be ill-defined, but it tends to spread and its features to become more pronounced. it may be limited to a certain region, or it may be more or less general. when fully developed, the skin is harsh and dry, of a mottled, reddish or violaceous color, thickened, infiltrated and usually slightly scaly, with, at times, a tendency toward the formation of oozing areas. punctate and linear scratch-marks may usually be seen scattered over the affected region. [illustration: fig. 21. eczema rubrum.] its most common site is the face, but it is not infrequent upon other parts. #what course does erythematous eczema pursue?# it tends to chronicity, continuing as the erythematous form, or the skin may become considerably thickened and markedly scaly, constituting eczema squamosum; or a moist oozing surface, with more or less crusting, may take its place--eczema rubrum. #describe the symptoms of papular eczema.# papular eczema (_eczema papulosum_) is characterized by the appearance, usually in numbers, of discrete, aggregated or closely-crowded, reddish, pin-head-sized acuminated or rounded papules. vesicles and vesico-papules are often intermingled. the itching is commonly intense, as often attested by the presence of scratch-marks and blood crusts. [illustration: fig. 22. eczema squamosum et tissum.] it is seen most frequently upon the extremities, especially the flexor surfaces. #what course does papular eczema pursue?# the lesions tend, sooner or later, to disappear, but are usually replaced by others, the disease thus persisting for weeks or months; in places where closely crowded, a solid, thickened, scaly sheet of eruption may result--eczema squamosum. #describe the symptoms of vesicular eczema.# vesicular eczema (_eczema vesiculosum_) usually appears, on one or several regions, as more or less diffused inflammatory reddened patches, upon which rapidly develop numerous closely-crowded pin-point to pin-head-sized vesicles, which tend to become confluent and form a solid sheet of eruption. the vesicles soon mature and rupture, the discharge drying to yellowish, honeycomb-like crusts. the oozing is usually more or less continuous, or the disease may decline, the crusts be cast off, to be quickly followed by a new crop of vesicles. in those cases in which the process is markedly acute, considerable swelling and [oe]dema are present. scattered papules, vesico-papules and pustules may usually be seen upon the involved area or about the border. the face in infants (_crusta lactea_, or _milk crust_, of older writers), the neck, flexor surfaces and the fingers are its favorite localities. #what course does vesicular eczema pursue?# usually chronic, with acute exacerbations. not infrequently it passes into eczema rubrum. #describe the symptoms of pustular eczema.# pustular eczema (_eczema pustulosum_, _eczema impetiginosum_) is probably the least common of all the varieties. it is similar, although usually less actively inflammatory, in its symptoms to eczema vesiculosum, the lesions being pustular from the start or developing from preëxisting vesicles; not infrequently the eruption is mixed, the pustules predominating. there is a marked tendency to rupturing of the lesions, the discharge drying to thick, yellowish, brownish or greenish crusts. its most common sites are the scalp and face, especially in young people and in those who are ill-nourished and strumous. #what course does pustular eczema pursue?# usually chronic, continuing as the same type, or passing into eczema rubrum. #describe the symptoms of squamous eczema.# squamous eczema (_eczema squamosum_) may be defined as a clinical variety, the chief symptoms of which are a variable degree of scaliness, more or less thickening, infiltration, and redness, with commonly a tendency to cracking or fissuring of the skin, especially when the disease is seated about the joints. it is developed, as a rule, from the erythematous or papular type. itching is slight or intense. the disease is not uncommon upon the scalp. #what is the course of squamous eczema?# essentially chronic. [illustration: fig. 23. eczema of the face and scalp.] #describe the symptoms of eczema rubrum.# eczema rubrum is characterized by a red, raw-looking, weeping, oozing or discharging surface, attended with more or less inflammatory thickening, infiltration and swelling; the exudation, consisting of serum, sometimes bloody, dries into thick yellowish or reddish-brown crusts. at one time the whole diseased area may be hidden under a mass of crusting, at other times a red, raw-looking, weeping surface (_eczema madidans_) is the most striking feature. itching is slight or intense, or the subjective symptom may be a feeling of burning. it is an important clinical type, usually developing from the vesicular, pustular or other primary variety. it is common about the face and scalp in children, and the middle and lower part of the leg in elderly people. #what is the course of eczema rubrum?# chronic, varying in intensity from time to time. #describe the symptoms of fissured eczema.# the conspicuous symptom is a marked tendency to fissuring or cracking of the skin (_eczema fissum_; _eczema rimosum_). this tendency is usually a part of an erythematous or squamous eczema, the fissuring constituting the most conspicuous and troublesome symptom. _chapping_ is an extremely mild but familiar example of this type. it is especially common about the hands and fingers. #what is the course of fissured eczema?# it is more or less persistent, the tendency to fissuring varying considerably according to the state of the weather, often disappearing spontaneously in the summer months. #describe eczema sclerosum and eczema verrucosum.# in eczema sclerosum the skin is thickened, infiltrated, hard, and almost horny. eczema verrucosum presents similar conditions, but, in addition, displays a tendency to papillary or wart-like hypertrophy. in both varieties the disease is usually seated about the ankle or the foot, developing from the papular or squamous type. they are uncommon, and obstinately chronic. #state the nature of the subjective symptoms in eczema.# itching, commonly intense, is usually a conspicuous symptom; it may be more or less paroxysmal. in some cases burning and heat constitute the main subjective phenomena. #is eczema accompanied by febrile or systemic symptoms?# no. in rare instances, in acute universal eczema, slight febrile action, or other systemic disturbance, may be noted at the time of the outbreak. #is the eczematous eruption (patch or patches) sharply defined against the neighboring sound skin?# no. in almost all instances the diseased area merges gradually and imperceptibly into the surrounding healthy integument. #what is the character of eczema as regards the degree of inflammatory action?# the inflammatory action may be acute, subacute or sluggish in character, and may be so from the start and so continue throughout its whole course; or it may, as is usually the case, vary in intensity from time to time. #state the character of eczema as regards duration.# as a rule, it is a persistent disease, showing little, if any, tendency to spontaneous disappearance. #is eczema influenced by the seasons?# yes. with comparatively few exceptions the disease is most common and much worse in cold, windy, winter weather. #to what may eczema be ascribed?# eczema may be due to constitutional or local causes, or to both. it may be considered, in fact, as a reaction of the skin tissues against some irritant, and the latter may have its origin from within or without. #name some of the important constitutional or predisposing causes.# gouty diathesis, rheumatic diathesis, disorders of the digestive tract, general debility or lack of tone, an exhausted state of the nervous system, dentition and struma. #is a constitutional cause sufficient to provoke an attack?# yes; but often the attack is brought about in those so predisposed by some local or external irritant. #mention some of the external causes.# heat and cold, sharp, biting winds, excessive use of water, strong soaps, vaccination, dyes and dyestuffs, chemical irritants, and the like. there is a growing belief that some cases presenting eczematous aspects are probably parasitic in origin. in fact, some observers hold to the microbic view of all cases of eczema. contact with the rhus plants, while producing a peculiar dermatitis, usually running an acute course terminating in recovery, may, in those predisposed, provoke a veritable and persistent eczema. in fact, in our examination as to causes in a given case, especially of the hands and face, all possible exciting factors should be inquired into, such as the handling of plants, chemicals, dyes, etc. [illustration: fig. 24. eczema of face.] #is eczema contagious?# no. the acceptance of a parasitic cause for the disease, however, necessarily carries with it the possibility of contagiousness under favoring conditions. such is not supported, however, by practical experience. #what is the pathology?# the process is an inflammatory one, characterized in all cases by hyperæmia and exudation, varying in degree according to the intensity and duration of the disease. the rete and papillary layer are especially involved, although in severe and chronic cases the lower part of the corium and even the subcutaneous tissue may share in the process. #do the cutaneous manifestations of the eruptive fevers bear resemblance to the erythematous type of eczema?# scarlatina and erysipelas may, to a slight extent, but the presence or absence of febrile and other constitutional symptoms will usually serve to differentiate. #what common skin diseases resemble some phases of eczema?# psoriasis, seborrh[oe]a, sycosis, scabies and ringworm. #how would you exclude psoriasis in a suspected case of eczema (squamous eczema)?# psoriasis occurs in variously-sized, rounded, _sharply-defined_ patches, usually scattered irregularly over the general surface, with special predilection for the elbows and knees. they are covered more or less abundantly with whitish, silvery or mother-of-pearl colored imbricated scales. the patches are always dry, and itching is, as a rule, slight, or may be entirely absent. eczema, on the contrary, is often localized, appearing as one or more large, irregularly diffused patches; it merges imperceptibly into the sound skin, and there is often a history of characteristic serous or gummy oozing; the scaling is usually slight and itching almost invariably a prominent symptom. #how would you exclude seborrh[oe]a (eczema seborrhoicum) in a suspected case of eczema?# seborrh[oe]a of the scalp is more commonly over the whole of that region and is relatively free from inflammatory symptoms; the scales are of a greasy character and the itching is usually slight or nil. on the other hand, in eczema of this region the parts are rarely invaded in their entirety; there may be at times the characteristic serous or gummy oozing; inflammatory symptoms are usually well-marked, the scales are dry and the itching is, as a rule, a prominent symptom. these same differences serve to differentiate the diseases in other regions. #how does scabies differ from eczema?# scabies differs from eczema in its peculiar distribution, the presence of the burrows, the absence of any tendency to patch formation, and usually by a clear history of contagion. #how would you exclude ringworm in a suspected case of eczema?# ringworm is to be distinguished by its circular form, its fading in the centre, and in doubtful cases by microscopic examination of the scrapings. #how does eczema differ from sycosis?# sycosis is limited to the hairy region of the face, is distinctly a follicular inflammation, and is rarely very itchy; eczema is diffused, usually involves other parts of the face, and itching is an annoying symptom. #state the general prognosis of eczema.# the disease is, under favorable circumstances, curable, some cases yielding more or less readily, others proving exceedingly rebellious. the length of time to bring about a result is always uncertain, and an opinion on this point should be guarded. #upon what would you base your prognosis in the individual case?# the extent of disease, its duration and previous behavior, the removability of the exciting and predisposing causes, and the attention the patient can give to the treatment. in eczema involving the lips, face, scrotum, and leg, and especially when this last-named exhibits a varicose condition of the veins, a cure is effected, as a rule, only through persistent and prolonged treatment. #does eczema ever leave scars?# no. upon the legs, in long-continued cases, more or less pigmentation usually remains. #how is eczema treated?# as a rule, eczema requires for its removal both constitutional and external treatment. certain cases, however, seem to be entirely local in their nature, and in these cases external treatment alone will have satisfactory results. #what general measures as to hygiene and diet are commonly advisable?# fresh air, exercise, moderate indulgence in calisthenics, regular habits, a plain, nutritious diet; abstention from such articles of food as pork, salted meat, acid fruits, pastry, gravies, sauces, cheese, pickles, condiments, excessive coffee or tea drinking, etc. as a rule, also, beer, wine, and other stimulants are to be interdicted. #upon what grounds is the line or plan of constitutional treatment to be based?# upon indications in the individual case. a careful examination into the patient's general health will usually give the cue to the line of treatment to be adopted. #mention the important remedies variously employed in the constitutional treatment.# _tonics_--such as cod-liver oil, quinine, nux vomica, the vegetable bitters, iron, arsenic, malt, etc. _alkalies_--sodium salicylate, potassium bicarbonate, liquor potassæ, and lithium carbonate. _alteratives_--calomel, colchicum, arsenic, and potassium iodide. _diuretics_--potassium acetate, potassium citrate, and oil of copaiba. _laxatives_--the various salines, aperient spring waters, castor oil, cascara sagrada, aloes and other vegetable cathartics. _digestives_--pepsin, pancreatin, muriatic acid and the various bitter tonics. #are there any remedies which have a specific influence?# no; although arsenic, in exceptional instances, seems to exert a special action. cod-liver oil is also of great value in some cases. upon the whole the most important remedies are those which keep in view the maintenance of a proper and healthful condition of the gastro-intestinal tract, and especially with regular and rather free action of the bowels. #in what class of cases does arsenic often prove of service?# in the sluggish, dry, erythematous, scaly and papular types. #in what cases is arsenic usually contraindicated?# it should never be employed in acute cases; nor in any instance (unless its action is watched), in which the degree of inflammatory action is marked, as an aggravation of the disease usually results. #what should be the character of the external treatment?# it depends mainly upon the degree of inflammatory action; but the stage of the disease, the extent involved, and the ability of the patient to carry out the details of treatment, also have a bearing upon the selection of the plan to be advised. #what is to be said about the use of soap and water in eczema?# in acute and subacute conditions soap and water are to be employed, as a rule, as infrequently and as sparingly as possible, as the disease is often aggravated by their too free use. washing is necessary, however, for cleanliness and occasionally, also, for the removal of the crusts. on the other hand, in chronic, sluggish types the use of soap and water frequently has a therapeutic value. #how often should remedial applications be made?# usually twice daily, although in some case, and especially those of an acute type, applications should be made every few hours. #mention several remedies or plans of treatment to be used in the acute or actively inflammatory cases.# black wash and oxide-of-zinc ointment conjointly, the wash thoroughly dabbed on, allowed to dry, the parts gently smeared with ointment; or the ointment may be applied spread on lint as a plaster. boric-acid wash (15 grains to the ounce) and oxide-of-zinc ointment, applied in the same manner as the above. a lotion containing calamine and zinc oxide, the sediment drying and coating over the affected surface:- [rx] calaminæ, zinci oxidi, ... [=a][=a] ......... [dram]ij-[dram]iij glycerinæ, alcoholis, ..... [=a][=a] ......... f[dram]ss liq. calcis, ...................... f[oz]ij aquæ, .......... q.s. ad .......... f[oz]vj. m. another excellent lotion somewhat similar to the last, but of oily character, is made up of three drachms each of calamine and zinc oxide, one drachm of boric acid, ten to thirty drops of carbolic acid, and three ounces each of lime-water and oil of sweet almonds. carbolic-acid lotion, about two drachms to the pint of water, to which may be added two or three drachms each of glycerin and alcohol; or, if there is intense itching, carbolic acid may be added to the several washes already mentioned. a lotion made of one or two drachms of liquor carbonis detergens[a] to four ounces of water. the following wash, especially in the dry form of the disease:- [rx] ac. borici, .......................... [dram]iv ac. carbolici, ....................... [dram]j glycerinæ, ........................... [dram]ij alcoholis, ........................... [dram]ij aquæ, ............. q.s. ad .......... oj. m. [footnote a: liquor carbonis detergens is made by mixing together nine ounces of tincture soap bark and four ounces of coal tar, allowing to digest for eight days, and filtering. the tincture of soap bark used is made with one pound of soap bark to one gallon of 95 per cent. alcohol, digesting for a week or so. instead of the proprietary name above, prof. duhring has suggested that of tinctura picis mineralis comp.] dusting-powders, of starch, zinc oxide and venetian talc, alone or severally combined, applied freely and often, so as to afford protection to the inflamed surface:- [rx] talci venet, zinci oxidi, ....... [=a][=a] ........ [dram]iv amyli, ............................... [oz]j m. if washes or dusting-powders should disagree or are not desirable or practicable, ointments may be employed, such as-oxide-of-zinc ointment, cold cream, petrolatum, plain or carbolated, diachylon ointment (if fresh and well prepared), and a paste-like ointment, as the following, usually called "salicylic-acid paste"; in markedly itchy cases, five to fifteen grains of carbolic may be added to each ounce: [rx] ac. salicylici, ...................... gr. v-x pulv. amyli, pulv. zinci oxidi, .... [=a][=a] ..... [dram]ij petrolati, ........................... [dram]iv m. or the following ointment:- [rx] calaminæ, ............................ [dram]j ungt. zinci oxidi, ................... [dram]vij. m. #name several external remedies and combinations useful in eczema of a subacute or mildly inflammatory type.# the various remedies and combinations useful when the symptoms are acute or markedly inflammatory (mentioned above), and more especially the several following:- [rx] zinci oxidi, ......................... [dram]ij liq. plumbi subacetat. dilut., ....... f[dram]vj glycerinæ, ........................... f[dram]ij infus. picis liq., ................... f[oz]iij m. a lotion containing resorcin, five to thirty grains to the ounce. solution of zinc sulphate, one-half to three grains to the ounce. an ointment containing calomel or ammoniated mercury, as in the annexed formula:- [rx] hydrargyri ammoniat. seu hydrargyri chloridi mit., ................... gr. x-xxx ac. carbolici, ..................... gr. v-x ungt. zinci oxidi, ................. [oz]j m. another formula, more especially useful in eczema of the hands and legs, is the following:- [rx] ac. salicylici, ...................... gr. xxx emp. plumbi, emp. saponis, petrolati, ...... [=a][=a] ........... [oz]j. m. (this is to be applied as a plaster, spread on strips of lint, and changed every twelve or twenty-four hours.) the paste-like ointment, referred to as useful in acute eczema, may also be used with a larger proportion (20 to 60 grains to the ounce) of salicylic acid. the following, containing tar, may often be employed with advantage:- [rx] ungt. picis liq., .................... [dram]j ungt. zinci oxidi, ................... [dram]vij. m. #what is to be said in regard to the use of tarry applications?# ointments or lotions containing tar should always be tried at first upon a limited surface, as occasionally skins are met with upon which this remedy acts as a more or less violent irritant. the coal tar lotion (liquor carbonis detergens) is the least likely to disagree and may be used as a mild ointment, one or two drachms to the ounce, or it may be diluted and used as a weak lotion as already referred to. #what external remedies are to be employed in eczema of a sluggish type?# the various remedies and combinations (mentioned above) useful in acute and subacute eczema may often be employed with benefit, but, as a rule, stronger applications are necessary, especially in the thick and leathery patches. the following are the most valuable:-an ointment of calomel or ammoniated mercury; forty to sixty grains to the ounce. strong salicylic-acid ointment; a half to one drachm of salicylic acid to the ounce of lard. tar ointment, official strength; or the various tar oils, alone or with alcohol, as a lotion, or in ointment form. liquor picis alkalinus[b] is a valuable remedy in chronic _thickened_, _hard_ and _verrucous_ patches, but is a strong preparation and must be used with caution. it is applied diluted, one part with from eight to thirty-two parts of water; or in ointment, one or two drachms to the ounce. in such cases, also, the following is useful:- [rx] saponis viridis, picis liq., alcoholis, .......... [=a][=a] ....... [dram]iij. m. sig. to be well rubbed in. [footnote b: [rx] potassæ, ............................. [dram]j picis liq., .......................... [dram]ij aquæ, ................................ [dram]v. dissolve the potash in the water, and gradually add to the tar in a mortar, with thorough stirring.] in similar cases, also, the parts may be thoroughly washed or scrubbed with sapo viridis and hot water until somewhat tender, rinsed off, dried, and a mild ointment applied as a plaster. lactic acid, applied with one to ten or more parts of water is also of value in the sclerous and verrucous types. caustic potash solutions, used cautiously, may also be occasionally employed to advantage in these cases. another remedy of value in these cases, as well as in others of more or less limited nature, is the _x_-ray. exposures every few days, of short duration and 4 to 10 inches distance, with medium vacuum tube. this method has served me well in occasional cases; caution is necessary, and it should not be pushed further than the production of the mildest reaction. the repeated application of a high-frequency current, by means of the vacuum electrodes, is a safer and sometimes an equally beneficial method. #is there any method of treating eczema with fixed dressings?# several plans have been advised from time to time; some are costly, and some require too great attention to details, and are therefore impracticable for general employment. the following are those in more common use:-the _gelatin dressing_, as originally ordered, is made by melting over a water-bath one part of gelatin in two parts of water--quickly painting it over the diseased area; it dries rapidly, and to prevent cracking glycerine is brushed over the surface. or the glycerine may be incorporated with the gelatin and water in the following proportion: glycerine, one part; gelatin, four parts, and water eight parts. medicinal substances may be incorporated with the gelatin mixture. a good formula is the following:- [rx] gelatin, ............................. [oz]j zinci oxidi, ......................... [oz]ss glycerini, ........................... [oz]iss aquæ, ................................ [oz]ii-[oz]iij. this should be prepared over a water-bath, and two per cent. ichthyol added. a thin gauze bandage can be applied to the parts over which this dressing is painted, before it is completely dry; it makes a comfortable fixed dressing and may remain on several days. _plaster-mull_ and _gutta-percha plaster_. the plaster-mull, consisting of muslin incorporated with a layer of stiff ointment, and the gutta-percha plaster, consisting of muslin faced with a thin layer of india-rubber, the medication being spread upon the rubber coating. _rubber plasters._ these are medicated with the various drugs used in the external treatment of skin diseases, and are often of service in chronic patches. two new excipients for fixed dressings have recently been introduced--bassorin and plasment; the former is made from gum tragacanth, and the latter from irish moss. the following is a satisfactory formula for a tragacanth dressing: [rx] tragacanth, .......................... gr. lxxv glycerini, ........................... [minim] xxx ac. carbolici, ....................... gr. x-xx zinci oxidi, ......................... [dram]iss-[dram]iiss. m. this is painted over the parts and allowed to dry, and a mild dusting powder sprinkled over. it cannot be used in warm weather or in folds, as it is apt to get sticky. the following is a bassorin paste which may be variously medicated. [rx] bassorin, ............................ [dram]x dextrin, ............................. [dram]vj glycerini, ........................... [oz]ij. aquæ, ....................... q.s. ad. [oz]iij. it should be prepared cold. another "drying dressing" which may be used in cool weather is: [rx] zinci oxidi, ......................... [oz]j glycerini, ........................... [oz]ss mucilag. acaciæ, ..................... [oz]ii-[oz]iv. it may be variously medicated. the plaster-mull is used in all types, especially the acute; the gelatin dressing, and the gutta-percha plaster, in the subacute and chronic; and the rubber plaster in chronic, sluggish patches only. acacia, tragacanth, bassorin and plasment applications are used in cases of a subacute and chronic character. #prurigo.# #define prurigo.# prurigo is a chronic, inflammatory disease, characterized by discrete, pin-headto small pea-sized, solid, firmly-seated, slightly raised, pale-red papules, accompanied by itching and more or less general thickening of the affected skin. #describe the symptoms and course of prurigo.# the disease first appears upon the tibial regions, and its earliest manifestation may be urticarial, but there soon develop the characteristic small, millet-seed-sized, or larger, firm elevations, which may be of the natural color of the skin or of a pinkish tinge. the lesions, whilst discrete, are in great numbers, and closely crowded. the overlying skin is dry, rough and harsh; itching is intense, and, as a result of the scratching, excoriations and blood crusts are commonly present. in consequence of the irritation, the inguinal glands are enlarged. sooner or later the integument becomes considerably thickened, hard and rough. eczematous symptoms may be superadded. in severe cases the entire extensor surfaces of the legs and arms, and in some instances the trunk also, are invaded. it is worse in the winter season. #what is known in regard to etiology and pathology?# it is a disease of the ill-fed and neglected, usually developing in early childhood, and persisting throughout life. it is extremely rare, even in its milder types, in this country. clinically and pathologically it bears some resemblance to papular eczema. #give the prognosis and treatment of prurigo.# the disease, in its severer types is, as a rule, incurable, but much can be done to alleviate the condition. good, nourishing food, pure air and exercise are of importance. tonics and cod-liver oil are usually beneficial. the local management is similar to that employed in chronic eczema. an ointment of [beta]-naphthol, one-half to five per cent. strength, is highly extolled. #acne.# #give a definition of acne.# acne is an inflammatory, usually chronic, disease of the sebaceous glands, characterized by papules, tubercles, or pustules, or a mixture of these lesions, and seated usually about the face. #at what age does acne usually occur?# between the ages of fifteen and thirty, at which time the glandular structures are naturally more or less active. #describe the symptoms of acne.# irregularly scattered over the face, and in some cases also over the neck, shoulders and upper part of the trunk, are to be seen several, fifty or more, pin-headto pea-sized papules, tubercles or pustules; commonly the eruption is of a mixed type (_acne vulgaris_), the several kinds of lesions in all stages of evolution and subsidence presenting in the single case. interspersed may generally be seen blackheads, or comedones. the lesions may be sluggish in character, or they may be markedly inflammatory, with hard and indurated bases. in the course of several days or weeks, the papules and tubercles tend gradually to disappear by absorption; or, and as commonly the case, they become pustular, discharge their contents, or dry and slowly or rapidly disappear, with or without leaving a permanent trace, new lesions arising, here and there, to take their place. in exceptional instances the eruption is limited to the back, and in these cases the eruption is usually extensive and persistent, and not infrequently leaves scars. #what do you understand by acne punctata, acne papulosa, acne pustulosa, acne indurata, acne atrophica, acne hypertrophica, and acne cachecticorum?# these several terms indicate that the lesions present are, for the most part, of one particular character or variety. #describe the lesions giving rise to the names of these various types.# blocking up of the outlet of the sebaceous gland (comedo), which is usually the beginning of an acne lesion, may cause a moderate degree of hyperæmia and inflammation, and a slight elevation, with a central yellowish or blackish point results--the lesion of _acne punctata_; if the inflammation is of a higher grade or progresses, the elevation is reddened and more prominent--_acne papulosa_; if the inflammatory action continues, the interior or central portion of the papule suppurates and a pustule results--_acne pustulosa_; the pustule, in some cases, may have a markedly inflammatory and hard base--_acne indurata_; and not infrequently the lesions in disappearing may leave a pit-like atrophy or depression--_acne atrophica_; or, on the contrary, connective-tissue new growth may follow their disappearance--_acne hypertrophica_; and, in strumous or cachectic individuals, the lesions may be more or less furuncular in type, often of the nature of dermic abscesses, usually of a cold or sluggish character, and of more general distribution--_acne cachecticorum_. #what is acne artificialis?# acne artificialis is a term applied to an acne or acne-like eruption produced by the ingestion of certain drugs, as the bromides and iodides, and by the external use of tar; this is also called _tar acne_. #what course does acne pursue?# essentially chronic. the individual lesions usually run their course in several days or one or two weeks, but new lesions continue to appear from time to time, and the disease thus persists, with more or less variation, for months or years. in many cases there is, toward the age of twenty-five or thirty, a tendency to spontaneous disappearance of the disease. [illustration: acne.] #is the eruption in acne usually abundant?# it varies in different cases and at different periods in the same case. in some instances, not more than five or ten papules and pustules are present at one time; in others they may be numerous. not infrequently several lesions make their appearance, gradually run their course, and the face continues free for days or one or two weeks. #does the eruption in acne disappear without leaving a trace?# in many instances no permanent trace remains, but in others slight or conspicuous scarring is left to mark the site of the lesions. #are there any subjective symptoms in acne?# as a rule, not; but markedly inflammatory lesions are painful. #state the immediate or direct cause of an acne lesion.# hypersecretion or retention of sebaceous matter. recent investigations point to the possibility of a special bacillus being the exciting cause, in some instances at least. the pyogenic cocci are added factors in the pustular and furuncular cases. #name the indirect or predisposing causes of acne.# digestive disturbance, constipation, menstrual irregularities, chlorosis, general debility, lack of tone in the muscular fibres of the skin, scrofulosis; and medicinal substances such as the iodides and bromides internally, and tar externally. working in a dusty or dirty atmosphere is often influential, resulting in a blocking-up of the gland ducts. workmen in paraffin oils or other petroleum products often present a furuncle-like acne. the disease is more common in individuals of light complexion. #is there any difficulty in the diagnosis of acne?# not if it be remembered that acne eruption is limited to certain parts and is always follicular, and that the several stages, from the comedo to the matured lesion, are usually to be seen in the individual case. #in what respect does the pustular syphiloderm differ from acne?# by its general distribution, the longer duration of the individual lesions, the darker color, and the presence of concomitant symptoms of syphilis. #what is the pathology of acne?# primarily, acne is a folliculitis, due to retention or decomposition of the sebaceous secretion or to the introduction of a micro-organism; subsequently, the tissue immediately surrounding becoming involved, with the possible destruction of the sebaceous follicle as a result. the degree of inflammatory action determines the character of the lesions. #state the prognosis of acne.# it is usually an obstinate disease, but curable. some cases yield readily, others are exceedingly rebellious, especially acne of the back. success depends in a great measure upon a recognition and removal of the predisposing condition. treatment is ordinarily a matter of months. #what measures of treatment are usually demanded in acne?# constitutional and local measures; the former when indicated, the latter always. #upon what is the constitutional treatment based?# upon indications. diet and hygienic measures are important. in dyspepsia and constipation, bitter tonics, alkalies, acids, pepsin, saline and vegetable laxatives, are variously prescribed. special mention may be made of the following:- [rx] ext. rhamni pursh. fl., .............. f[dram]ij-f[dram]iv tinct. nucis vom., ................... f[dram]iij tinct. cardamomi comp., .......q.s. ad [oz]iij. m. sig.--f[dram]t.d. or hunyadi janos or friedrichshall water may be employed for a laxative purpose. in chlorotic and anæmic cases the ferruginous preparations are of advantage. cod-liver oil is often a remedy of great value, and is especially useful in strumous and debilitated subjects. calx sulphurata in pill form, one-tenth to one-fourth grain four or five times daily, is said, acts well in the pustular variety. in some instances, more particularly in sluggish papular acne, arsenic, especially the sulphide of arsenic, acts favorably. upon the whole, the line of treatment that keeps in view proper and healthy action of the gastro-intestinal canal is the most successful. [illustration: acne of back.] in inflammatory cases occurring in robust individuals the following is often of service:- [rx] potassii acetat., .................... [dram]iv liq. potassæ, ........................ f[dram]ij liq. ammonii acetat., .... q.s. ad ... f[oz]iij. m. sig.--f[dram]j-f[dram]ij t.d., largely diluted. #state the character of the local treatment in acne.# this must vary somewhat with the local conditions. cases which are acute in character, in the sense that the lesions are markedly hyperæmic, tender and painful, require milder applications, and in exceptional instances soothing remedies are to be prescribed. as a rule, however, stimulating applications may be employed from the start. the remedies are, for obvious reasons, most conveniently applied at bedtime. #what preliminary measures are to be advised in ordinary acne cases?# washing the parts gently or vigorously, according to the irritability of the skin, with warm water and soap; subsequently rinsing, and sponging for several minutes with hot water, and rubbing dry with a soft towel; after which the remedial application is made. in sluggish and non-irritable cases sapo viridis or its tincture may often be advantageously used in place of the ordinary toilet soap. the blackheads, so far as practicable, are to be removed by pressure with the fingers or with a suitable instrument (see comedo), and the superficial pustules punctured and the contents pressed out. scraping the affected parts with a blunt curette is a valuable measure, but is temporarily disfiguring. as a rule, however, cases do just as well without puncturing and scraping, and these methods sometimes leave behind scarring. #state the methods of external medication commonly employed.# by ointments and lotions. if an ointment is used, it is to be thoroughly rubbed in, in small quantity; if a lotion is employed, it is to be well shaken, the parts freely dabbed with it for several minutes and then allowed to dry on. #state the object in view in local medication.# to hasten the maturation and disappearance of the existing lesions, and to stimulate the skin and glands to healthy action. if slight irritation or scaliness results, the application is to be intermitted one or two nights; in the meantime nothing except the hot-water sponging, with or without the application of a mild soothing ointment, is to be employed. #is it usually necessary to change from one external remedy to another in the course of treatment?# yes. after a certain time one remedy, as a rule, loses its effect, and a change from lotion to ointment or the reverse, and from one lotion or ointment to another, will often be found necessary in order to bring about continuous improvement. #name the various important remedies and combinations employed in the external treatment of acne.# sulphur is the most valuable. it may often be applied with benefit as a simple ointment:- [rx] sulphur, præcip., .................... [dram]ss-[dram]j adipis benz. lanolin, ............ [=a][=a] ....... [dram]ij. or it may be used as a lotion, as in the annexed formula:- [rx] sulphur, præcip., .................... [dram]iss pulv. tragacanthæ, ................... gr. x1 pulv. camphoræ, ...................... gr. xx liq. calcis, ........ q.s. ad ........ f[oz]iv. m. another lotion, especially useful in those cases in which an oily condition of the skin is present, is the following:- [rx] sulphur, præcip., .................... [dram]iss etheris, ............................. f[dram]iv alcoholis, ........................... f[oz]iijss. m. a compound lotion containing sulphur in one of its combinations is also valuable in many cases:- [rx] zinci sulphatis, potassii sulphureti, .... [=a][=a] ... [dram]ss-[dram]iv aquæ, ................................ [oz]iv. m. (the salts should be dissolved separately and then mixed; reaction takes place and the resulting lotion, when shaken, is milky in appearance, and free from odor; allowed to stand the particles settle, the sediment constituting about one-fourth to three-fourths of the whole bulk). at times the addition to this formula of several drachms of alcohol and of five to ten minims of glycerin is of advantage. an external remedy, often valuable, is ichthyol. it is thus prescribed:- [rx] ichthyol, ............................ [dram]ss-[dram]j cerat. simp., ........................ [dram]iv. m. the various mercurial ointments, especially one of white precipitate, five to fifteen per cent. strength, are sometimes beneficial. a compound lotion, containing mercury, which frequently proves serviceable, is:- [rx] hydrarg. chlorid. corros., ........... gr. ii-viij zinci sulphatis, ..................... gr. x-xx tinct. benzoini, ..................... f[dram]ij aquæ, ............ q.s. ad ........... f[oz]iv. in extremely sluggish cases the following, used cautiously, is of value:- [rx] ichthyol, saponis viridis, sulphur, præcip., lanolin, ............. [=a][=a] ...... [dram]j. in such instances the application of a strong alcoholic resorcin lotion, ten to twenty-five per cent. strength, repeated several times daily till marked irritation and exfoliation occur (a matter usually of one to three days), will sometimes be followed by marked improvement. acne of the back is treated with the same applications, but usually stronger; in this region applications of vleminckx's solution and formaldehyde solution, weakened considerably, at first at least, prove of value. _obstinate and indurated lesions_ may be incised, the contents pressed out, and the interior touched with carbolic acid by means of a pointed stick. the _x_-ray has proved a most valuable addition to our resources in the treatment of acne, and is especially serviceable in extensive and obstinate cases. an exposure should be made about twice weekly, at a distance of five to ten inches and for from three to ten minutes, and a tube of medium vacuum used. it must be used with great caution and never beyond the production of the mildest erythema. the hair, eyes, and lips should be protected. the _x_-ray treatment is best reserved for obstinate cases, and then used mildly, and rather as an adjuvant to the ordinary methods than as the sole measure. #what precaution is to be taken in advising a change from a sulphur to a mercurial preparation or the reverse?# several days should be allowed to intervene, otherwise a disagreeable, although temporary, staining or darkening of the skin results--from the formation of the black sulphuret of mercury. #acne rosacea.# #give a descriptive definition of acne rosacea.# acne rosacea is a chronic, hyperæmic or inflammatory disease, limited to the face, especially to the nose and cheeks, characterized by redness, dilatation and enlargement of the bloodvessels, more or less acne and hypertrophy. #describe the symptoms of acne rosacea.# the disease may be slight or well-marked. redness, capillary dilatation, and acne lesions seated on the nose and cheeks, and sometimes on chin and forehead also, constitute in most cases the entire symptomatology. a mild variety consists in simple redness or hyperæmia, involving the nose chiefly and often exclusively, and is to be looked upon as a passive congestion; this is not uncommon in young adults and is often associated with an oily seborrh[oe]a of the same parts. in many cases the condition does not progress beyond this stage. in other cases, however, sooner or later the dilated capillaries become permanently enlarged (_telangiectasis_) and acne lesions are often present--constituting the middle stage or grade of the disease; this is the type most frequently met with. in exceptional instances, still further hypertrophy of the bloodvessels ensues, the glands are enlarged, and a variable degree of connective-tissue new growth is added; this latter is usually slight, but may be excessive, the nose presenting an enlarged and lobulated appearance (_rhinophyma_). [illustration: fig. 25. acne rosacea.] #are there any subjective symptoms in acne rosacea?# as a rule, no. some of the acne lesions may be tender and painful, and at times there is a feeling of heat and burning. #what do you know in regard to the etiology?# in many cases the causes are obscure. chronic digestive and intestinal disorders, anæmia, chlorosis, continued exposure to heat or cold, menstrual and uterine irregularities, and the too free use of spirituous liquors, tea, etc. are often responsible factors. it is essentially a disease of adult life, common about middle age, occurring in both sexes, but rarely reaching the same degree of development in women as observed at times in men. #is acne rosacea easily recognized?# yes. the redness, acne lesions, dilated capillaries, and, at times, the glandular and connective-tissue hypertrophy; the limitation of the eruption to the face, especially the region of the nose; the evident involvement of the sebaceous glands, the absence of ulceration, taken with the history of the case, are characteristic. it is to be distinguished from the tubercular syphiloderm and lupus vulgaris, diseases to which it may bear rough resemblance. #state the prognosis of acne rosacea.# all cases may be favorably influenced by treatment; the mild and moderately-developed types are, as a rule, curable, but usually obstinate. it is a persistent disease, showing little, if any, tendency to disappear spontaneously. #what is the method of treatment?# both constitutional and local measures are demanded in most cases. #upon what is the constitutional treatment to be based?# the constitutional treatment, beyond a regulation of the diet, is to be based upon a correct appreciation of the etiological factors in the individual case. there are no special remedies. iron, cod-liver oil, tonics, ergot, alkalies, saline laxatives, and similar drugs are to be variously prescribed. #what is the external treatment?# in many respects, both as to the preliminary measures and remedies, essentially the same as that employed in the treatment of simple acne (_q. v._). the _x_-ray treatment is not so efficient in this disease, however, as in acne. in addition to the treatment there found, several other applications deserve mention:-in many cases _vleminckx's solution_[c] is valuable, applied diluted with one to ten parts of water. also, a mucilaginous paste containing sulphur:- [rx] mucilag. acaciæ, ..................... f[dram]iij glycerinæ, ........................... f[dram]ij sulphur, præcip., .................... [dram]iij. m. [footnote c: [rx] calcis, .............................. [oz]ss sulph. sublimat., .................... [oz]j aquæ, ................................ [oz]x. to be boiled down to [oz]vj and filtered.] or a similar paste with the glycerine in the foregoing replaced with ichthyol may be used. #in what manner are the dilated bloodvessels and connective-tissue hypertrophy to be treated?# the enlarged capillaries are to be destroyed by incision or by electrolysis. properly managed the vessels may be thus destroyed, but unless the predisposing causes have disappeared or have been remedied, a new growth may take place. if the knife is employed, the vessels are either slit in their length or cut transversely at several points. the method by electrolysis is the same as used in the removal of superfluous hair (_q. v._).; the needle may, if the vessel is short, be inserted along its calibre, or if long, may be inserted at several points in its length. excessive connective-tissue growth, exceptionally met with, is to be treated by ablation with the scissors or knife. #acne varioliformis.# (_synonyms:_ acne frontalis; acne rodens; acne necrotica; lupoid acne; necrotic granuloma.) #describe acne varioliformis.# acne varioliformis is characterized by lesions of a moderately superficial papulo-pustular type, which in disappearing leave slight or pit-like scars. the forehead and scalp are the favorite sites, but they may also occur elsewhere. the eruption is rather scanty as a rule, consisting usually of ten to thirty lesions. they begin as small maculo-papules, as papules, or as minute nodules in or on the skin, and gradually become small pea-sized, with a tendency to slight vesiculation or pustulation at the central part. the lesion is sluggish in its course, drying to a thin crust, which finally falls off, leaving a depressed variola-like scar. new lesions arise from time to time, and the disease thus continues almost indefinitely. there may or may not be itching. in what appears to be a variety of this disease, known usually as _acne urticata_, there is considerable itching just at the time the lesion is appearing. the malady is not frequent, but occurs in both sexes, usually in those between the ages of twenty and fifty. it seems probable that the eruption is parasitic in origin. the maladies variously known as hydradenitis suppurativa, acnitis, spiradenitis, folliclis, granuloma necroticum, etc., in which the lesions, primarily at least, are somewhat deeper seated, sluggish in their course, and followed by scarring, could be also included under this head. #give the prognosis and treatment.# the disease is rebellious and tends to recur. the most efficient applications are those of sulphur and resorcin, the same as prescribed in ordinary acne. #sycosis.# (_synonyms:_ sycosis vulgaris; sycosis non-parasitica; folliculitis barbæ; sycosis coccogenica.) #what do you understand by sycosis?# sycosis is a chronic, inflammatory affection involving the hair-follicles, usually of the moustache and bearded regions only, and characterized by papules, tubercles, and pustules perforated by hairs. #describe the symptoms of sycosis.# sycosis begins by the formation of papules and pustules about the hair-follicles; the lesions occur in numbers, in close proximity, and together with the accompanying inflammation, make up a small or large area. the pustules are small, rounded, flat or acuminated, discrete, and yellowish in color; they are perforated by hairs, show no tendency to rupture, and are apt to occur in crops, drying to thin yellowish or brownish crusts. papules and tubercles are often intermingled. more or less swelling and infiltration are noticeable. [illustration: fig. 26. sycosis--not infrequently begins in, and sometimes limited to, this region.] the disease is seen, as a rule, only on the bearded part of the face, either about the cheeks, chin or upper lip, involving a small portion or the whole of these parts. it is also sometimes met with involving the hair follicles just within the nasal orifice, and may even be limited to this region. occasionally a sycosiform eruption, usually of the side of the bearded region, leaves behind a smooth or keloidal scar, the disease gradually extending--_ulerythema sycosiforme_ (lupoid sycosis). an inflammation of the hair-follicles of the scalp apparently sycosiform in character, occurring as discrete or aggregated lesions, is sometimes observed, the follicles being destroyed and atrophy or slight scarring resulting--_folliculitis decalvans_. #does conspicuous hair loss occur in sycosis?# ordinarily not; the hairs are, especially at first, usually firmly seated, but in those cases in which suppuration is active, and has involved the follicles, they may, as a rule, be easily extracted. in some cases destruction of the follicles ensues and slight scarring and permanent hair loss result. #state the character of the subjective symptoms.# pain and itching and a sense of burning, variable as to degree, may be present. #what is the course of the disease?# essentially chronic, the inflammatory action being of a subacute or sluggish character, with acute exacerbations. #state the causes of sycosis.# upon the upper lip it may have its origin in a nasal catarrh. entrance into the follicles of pyogenic micrococci is now regarded as the essential factor. this view being accepted, carries with it the possibility of contagiousness. it is seen in the male sex only, usually in those between the ages of twenty-five and fifty; and is met with in those in good and bad health, and among rich and poor. it is comparatively infrequent. #what is the pathology of sycosis?# the disease is primarily a perifolliculitis, the follicle and its sheath subsequently becoming involved in the inflammatory process. #how would you distinguish sycosis from eczema?# eczema is rarely sharply limited to the bearded region, but is apt to involve other parts of the face; moreover, the lesions are usually confluent, and there is either an oozing, red crusted surface, or it is dry and scaly. #how would you exclude tinea sycosis in the diagnosis?# in tinea sycosis, or ringworm sycosis, the history of the case is different. the parts are distinctly lumpy and nodular; the hairs are soon involved and become dry, brittle, loose, and fall out, or they may be readily extracted. the superficial type of ringworm sycosis is readily distinguished by the ring-like character of the patches. in doubtful cases, microscopic examination of the hairs may be resorted to. #give the prognosis of sycosis.# the disease is curable, but almost invariably obstinate and rebellious to treatment. the duration, extent, and character of the inflammatory process must all be considered. an expression of an opinion as to the length of time required for a cure should always be guarded. ulerythema sycosiforme is extremely obstinate. folliculitis decalvans is also rebellious. #how is sycosis to be treated?# mainly, and often exclusively, by external applications. [illustration: fig. 27. sycosis.] #is constitutional treatment of no avail in sycosis?# in some instances; but, as a rule, it is negative. if indicated, such remedies as tonics, alteratives, cod-liver oil and the like are to be prescribed. #describe the external treatment.# crusting, if present, is to be removed by warm embrocations. if the inflammation is of a high grade, and the parts tender and painful, soothing applications, such as bland oils, black wash and oxide-of-zinc ointment, cold cream and petrolatum, are to be used; boric-acid solution, fifteen grains to the ounce, may be advised in place of black wash. in most cases, however, astringent and stimulating remedies are demanded from the start, such as: diachylon ointment, alone or with ten to thirty grains of calomel to the ounce; oleate of mercury, as a fiveto twenty-per-cent. ointment; precipitated sulphur, one to three drachms to the ounce of benzoated lard, or lard and lanolin; a tento twenty-five-per-cent. ichthyol ointment; and resorcin lotion or ointment, ten to twenty per cent. strength. [illustration: fig. 28. sycosis.] a change from one application to another will be found necessary in almost all cases. in obstinate cases the x-ray treatment can be used, as it has proved itself valuable in some instances; as in other diseases, it should be employed cautiously. #what would you advise in regard to shaving?# when bearable (and after a few days' application of soothing remedies it almost always is), it is to be advised in all cases, as it materially aids in the treatment. after a cure is effected it should be continued for some months, until the healthy condition of the parts is thoroughly established. #when is depilation advisable as a therapeutic measure?# when the suppurative process is active, in order to save the follicles from destruction; incising or puncturing the pustules will often accomplish the same end. depilation is in all cases a valuable therapeutic measure, but it is painful; as a routine practice, shaving is less objectionable and, upon the whole, is probably as satisfactory. those who make free use of the x-ray commonly push it to the point of producing depilation. #dermatitis papillaris capillitii.# (_synonym:_ acne keloid.) [illustration: fig. 29. dermatitis papillaris capillitii.] #describe dermatitis papillaris capillitii.# this is a peculiar, mildly inflammatory, sycosiform, keloidal, acne-like disease of the hairy border of the back of the neck, often extending upward to the occipital region; partaking, especially later in its course, somewhat of the nature of keloid. several or more acne-like lesions, papular and pustular, closely grouped or bunched, appear, developing slowly, usually to the size of peas; are red, pale red, or whitish, often enveloping small tufts of hair, and attended with more or less hair loss. its course is gradual and persistent. it is an exceedingly rare condition, the exact nature of which is still obscure. #give the treatment.# treatment, which is usually unsatisfactory, consists of stimulating applications--the same, in fact, as employed in sycosis, sulphur and ichthyol deserving special mention. depilation is essential. #impetigo contagiosa.# #give a descriptive definition of impetigo contagiosa.# impetigo contagiosa is an acute, contagious, inflammatory disease, characterized by the formation of discrete, superficial, flat, rounded, or ovalish vesicles or blebs, soon becoming vesico-pustular, and drying to thin yellowish crusts. #upon what parts does the eruption commonly appear?# upon the face, scalp, and hands, and exceptionally upon other regions. #describe the symptoms of impetigo contagiosa.# one, several or more small pin-head-sized papulo-vesicles or vesicles make their appearance, usually upon the face and fingers. in the male adult the region of the neck and beard is a favorite situation. they increase in size by extending peripherally, but are more or less flattened and umbilicated, and are without conspicuous areola. the lesions may attain the size of a dime or larger, and when close together may coalesce and form a large patch. in some cases distinct blebs result, and a picture of pemphigus eruption presented; it is probable that many of the cases of "contagious pemphigus" belong to this class. new lesions may appear for several days, but finally, in the course of a week or ten days, they have all dried to thin, wafer-like crusts, of a straw or light-yellow color, but slightly adherent, and appearing as if stuck on; these soon drop off, leaving faint reddish spots, which gradually fade. in some cases there is so decided a tendency to clear and dry up centrally while spreading peripherally that the eruption has a ring-like aspect; this seems especially so in the bearded region of the male adult. instead of presenting as described, it may occur as one or more peaor finger-nail-sized, rounded and elevated, usually firm, discrete pustules, scattered over one part, or more commonly over various regions, such as the face, hands, feet and lower extremities. the pustules are such from the beginning, and when developed are usually of the size of a pea or finger-nail, elevated, semi-globular or rounded, with somewhat thick and tough walls, and of a whitish or yellowish color; at first there may be a slight inflammatory areola, but as the lesion matures this almost, if not entirely, disappears. the pustules show no disposition to umbilication, rupture or coalescence; drying in the course of several days or a week to yellowish or brownish crusts, which soon drop off, leaving no permanent trace. this variety was formerly thought to be a distinct disease, and was described under the name of _impetigo simplex_. as a rule there are no constitutional symptoms, but in the more severe cases the eruption may be preceded by febrile disturbance and malaise. itching may or may not be present. #state the cause of the disease.# it is contagious, the contents of the lesions being inoculable and auto-inoculable. at times it seems to prevail in epidemic form. pyogenic microörganisms are now regarded as causative. a relationship to vaccination has been alleged by some observers. it is more commonly observed in infants and young children. #from what diseases is impetigo contagiosa to be differentiated?# from eczema, pemphigus, and ecthyma. #how does impetigo contagiosa differ from these several diseases?# by the character of the lesions, their growth, their superficial nature, their course, the absence of an inflammatory base and areola, the thin, yellowish, wafer-like crusts, and usually a history of contagion. #state the prognosis.# the effect of treatment is usually prompt. the disease, indeed, tends to spontaneous disappearance in two to four weeks; in exceptional instances, more especially in those cases in which itching is present, the excoriations or scratch-marks become inoculated, and in this way it may persist several weeks. #what is the treatment of impetigo contagiosa?# treatment consists in the destruction of the auto-inoculable properties of the contents of the lesions; this is effected by removing the crusts by means of warm water-and-soap washings, and subsequently rubbing in an ointment of ammoniated mercury, ten to twenty grains to the ounce. some cases respond more rapidly to the use of a drying ointment, such as lassar's paste, with ten to twenty grains of white precipitate or sulphur to the ounce. in itching cases, a saturated solution of boric acid, or a carbolic-acid lotion, one to two drachms to the pint, is to be employed for general application. #impetigo herpetiformis.# #describe impetigo herpetiformis.# impetigo herpetiformis is an extremely rare disease, observed usually in pregnant women, and is characterized by the appearance of numerous isolated and closely-crowded pin-head-sized superficial pustules, which show a decided disposition to the formation of circular groups or patches. the central portion of these groups dries to crusts, while new pustules appear at the peripheral portion. they tend to coalesce, and in this manner a greater part of the whole surface may, in the course of weeks or months, become involved. profound constitutional disturbance, usually of a septic character, precedes and accompanies the disease; in almost every instance a fatal termination sooner or later results. it is possibly a grave type of dermatitis herpetiformis. #ecthyma.# #give a descriptive definition of ecthyma.# ecthyma is a disease characterized by the appearance of one, several or more discrete, finger-nail-sized, flat, usually markedly inflammatory pustules. #describe the symptoms and course of ecthyma.# the lesions begin as small, usually pea-sized, pustules; increase somewhat in area, and when fully developed are dime-sized, or larger, somewhat flat, with a markedly inflammatory base and areola. at first yellowish they soon become, from the admixture of blood, reddish, and dry to brownish crusts, beneath which will be found superficial excoriations. the individual pustules are usually somewhat acute in their course, but new lesions may continue to appear from day to day or week to week. as a rule, not more than five to twenty are present at one time, and in most cases they are seated on the legs. more or less pigmentation, and sometimes superficial scarring, may remain to mark the site of the lesions. itching is rarely present, but there may be more or less pain and tenderness. #what is the cause of ecthyma?# it is essentially a disease of the poorly cared-for and ill-fed; the direct exciting cause is the introduction of pyogenic microörganisms into the follicular openings. it is closely allied to impetigo contagiosa, and may in fact be regarded as a markedly inflammatory form of the latter affection. it seems much less contagious, however. it is commonly observed in male adults. #from what diseases is ecthyma to be differentiated?# from impetigo contagiosa, and the flat pustular syphiloderm. #how is it distinguished from these several diseases?# the size, shape, inflammatory action, and the depraved general condition, the distribution and lesser-contagiousness will distinguish it from impetigo contagiosa; and the absence of concomitant symptoms of syphilis, and of positive ulceration, as well as its distribution and more rapid and inflammatory course, will exclude the pustular syphiloderm. #state the prognosis.# the disease is readily curable, disappearing upon the removal of the predisposing cause and the employment of local antiseptic applications. #what treatment is to be advised?# good food, proper hygiene and tonic remedies; and, locally, removal of the crusts and stimulation of the underlying surface with an ointment of ammoniated mercury, ten to thirty grains to the ounce. the following mild antiseptic lotion, which materially lessens the tendency to the formation of new lesions, may be applied to the affected region two or three times daily:- [rx] acidi borici, ........................ [dram]iv resorcini, ........................... [dram]ij glycerinæ, ........................... f[dram]ij alcoholis, ........................... f[oz]j aquæ, ........... q.s. ad ............ oj. m. a weak lotion of thymol, corrosive sublimate or ichthyol would doubtless be equally effectual. #pemphigus.# #what do you understand by pemphigus?# pemphigus is an acute or chronic disease characterized by the successive formation of irregularly-scattered, variously-sized blebs. #name the varieties met with.# two varieties are usually described--pemphigus vulgaris and pemphigus foliaceus. #describe the symptoms and course of pemphigus vulgaris.# with or without precursory symptoms of systemic disturbance, irregularly scattered blebs, few or in numbers, make their appearance, arising from erythematous spots or from apparently normal skin. they vary in size from a pea to a large egg, are rounded or ovalish, usually distended, and contain a yellowish fluid which, later, becomes cloudy or puriform. if ruptured, the rete is exposed, but the skin soon regains its normal condition; if undisturbed, the fluid usually disappears by absorption. each lesion runs its course in several days or a week. a grave type of pemphigus is exceptionally observed in the newborn--_pemphigus neonatorum_. #what course does pemphigus vulgaris pursue?# usually chronic. the disease may subside in several months and the process come to an end, constituting the acute type. as a rule, however, the disease is chronic, new blebs continuing to appear from time to time for an indefinite period. [illustration: fig. 30. pemphigus (mulatto).] #in what respects does the severe form of pemphigus vulgaris differ from the ordinary type?# in the severe or malignant type the eruption is more profuse; there is marked, and often grave, systemic depression, and the lesions are attended with ulcerative action. #describe the symptoms and course of pemphigus foliaceus.# in this, the grave type of the disease, the blebs are loose and flaccid, with milky or puriform contents, rupturing and drying to crusts, which are cast off, disclosing the reddened corium. new blebs appear on the sites of disappearing or half-ruptured lesions, and the whole surface may be thus involved and the disease continue for years, compromising the general health and eventually ending fatally. in some cases of pemphigus (pemphigus vegetans) a vegetating or papillomatous condition develops from the base of the lesion, with an offensive discharge; it is usually a grave type of the malady. exceptionally cases (dermatitis vegetans) are met with which have a close similarity in their symptoms to pemphigus vegetans, but in which the eruption is more or less limited to the genitocrural region. the disorder is not malignant and usually yields to cleanliness and antiseptics. #what is the character of the subjective symptoms in pemphigus?# the subjective symptoms consist variously of heat, tenderness, pain, burning and itching, and may be slight or troublesome. #what is known in regard to the etiology of pemphigus?# the causes are obscure; general debility, overwork, shock, nervous exhaustion, and septic conditions (microörganisms) are thought to be of influence. there seems no doubt that those who have to do with cattle products, especially butchers, are subjects of acute and usually grave pemphigus. vaccination has exceptionally been responsible for the disease, probably through some coincidental infection. the disease is not contagious, nor is it due to syphilis. it may occur at any age. it is a rare disease, especially in this country. most of the cases diagnosed as pemphigus by the inexperienced are examples of bullous urticaria, bullous erythema multiforme, and impetigo contagiosa. #what is the pathology?# the lesions are superficially seated, usually between the horny layer and upper part of the rete. round-cell infiltration and dilated blood vessels are found about the papillæ and in the subcutaneous tissue. the contents of the blebs, always of alkaline reaction, are at first serous, later containing blood corpuscles, pus, fatty-acid crystals, epithelial cells, and occasionally uric acid crystals and free ammonia. #from what diseases is pemphigus to be differentiated?# from herpes iris, the bullous syphiloderm, impetigo contagiosa and dermatitis herpetiformis. #how do these several diseases differ from pemphigus?# the acute course, small lesions, concentric arrangement, variegated colors, and distribution, in herpes iris; the thick, bulky, greenish crusts, the underlying ulceration, the course, history, and the presence of concomitant symptoms of syphilis, in the bullous syphiloderm; the history, course, distribution, the character of the crusting, and the contagious and auto-inoculable properties of the contents of the lesions, in impetigo contagiosa; the tendency to appear in groups, the smaller lesions, the intense itchiness, course, multiform characters of the eruption and the disposition to change of type in dermatitis herpetiformis,--will serve as differential points. #state the prognosis of pemphigus.# its duration is uncertain, and the issue may in severe cases be fatal. in the milder types, after months or several years, recovery may take place. the extent and severity of the disease and the general condition of the patient are always to be considered before an opinion is expressed. pemphigus neonatorum usually ends fatally. #give the treatment of pemphigus.# both constitutional and local measures are demanded. good nutritious food and hygienic regulations are essential. arsenic and quinia are the most valuable remedies. the former, in occasional instances, seems to have a specific influence, and should always be tried, beginning with small doses and increasing gradually to the point of tolerance and continued for several weeks or longer. the remedy should not be set aside as long as there are signs of improvement, unless the supervention of stomachic, intestinal or other disturbance demand its discontinuance. other tonics, such as iron, strychnia and cod-liver oil, are also at times of service. the blebs should be opened and the parts anointed or covered with a mild ointment. in more general cases bran, starch and gelatin baths, and in severe cases the continuous bath, if practicable, are to be used. #class iii.--hemorrhages.# #purpura.# #define purpura.# purpura is a hemorrhagic affection characterized by the appearance of variously-sized, usually non-elevated, smooth, reddish or purplish spots or patches, not disappearing under pressure. #name the several varieties met with.# three--purpura simplex, purpura rheumatica and purpura hæmorrhagica; denoting, respectively, the mild, moderate and severe grade of the disease. the division is, to a great extent, an arbitrary one. #describe the clinical appearance and course of an individual lesion of purpura.# the spot, which may be pin-head, pea-, bean-sized or larger, appears suddenly, and is of a bright red or purplish red color. its brightness gradually fades, the color changing to a bluish, bluish-green, bluishor greenish-yellow, dirty yellowish, yellowish-white, and finally disappearing; varying in duration from several days to several weeks. #describe the symptoms of purpura simplex.# purpura simplex, or the mild form, shows itself as pin-point to peaor bean-sized, bright or dark-red spots, limited, as a rule, to the limbs, especially the lower extremities; fading gradually away and coming to an end in a few weeks, or new crops appearing irregularly for several months. there is rarely any systemic disturbance, and, as a rule, no subjective symptoms; in exceptional cases an urticarial element is added--_purpura urticans_. #describe the symptoms of purpura rheumatica.# purpura rheumatica (also called _peliosis rheumatica_) is usually preceded by symptoms of malaise, rheumatic pains and sometimes swelling about the joints; these phenomena abate and frequently disappear upon the outbreak of the eruption. the lesions are peato dime-sized, smooth, non-elevated, or slightly raised, and of a reddish or purplish color; the eruption may be more or less generalized, most abundant upon the limbs, or it may be limited to these parts. it may end in a few weeks, or may persist for several months, new spots appearing irregularly or in the form of crops. as somewhat allied to this is another form (_schönlein's disease_), quite alarming in its symptoms. it is rare. it is characterized by symptoms partaking of the nature of rheumatism, purpuric spots, blotches and ecchymoses, erythema multiforme, and often associated with considerable edema. the throat is also usually invaded, and indeed the first symptom is commonly in this region. considerable constitutional disturbance, of a threatening character, is commonly observed. recovery usually takes place. _henoch's purpura_, observed chiefly in children, resembles the above, with the erythema multiforme character and the [oe]dematous swellings more pronounced, while the actual purpuric symptoms are less conspicuous. gastric and intestinal symptoms and hemorrhages from the mucous membrane are commonly noted. it is fatal in about 20 per cent. of the cases. #describe the symptoms of purpura hæmorrhagica.# purpura hæmorrhagica (also called _land scurvy_) is characterized usually by premonitory, and frequently accompanying, symptoms of general distress, and by the appearance of coin to palm-sized, red or purplish hemorrhagic spots or patches, smooth, non-elevated or raised. hemorrhage from the mouth, gums and other parts, slight or serious in character, may occur. new lesions continue to appear for several days or weeks; and in exceptional instances, repeated relapses take place, and the disease thus persists for months. it may end fatally. #state the etiology of purpura.# in most instances no cause can be assigned. the disease occurs at all ages from childhood to advanced life, and in individuals, apparently, in good and bad health alike. the hemorrhagic type is oftener seen in subjects debilitated or in a depraved state of health. a microörganism is also looked upon as a factor by some observers, especially in the grave type of disease. #state the diagnostic characters of purpura.# the appearance, irregularly or in crops, of bright-red or purplish spots, evidently of hemorrhagic nature, and not _disappearing upon pressure_, and as they are fading, going through the several changes of color usually observed in any ecchymosis. #how does scurvy (scorbutus) differ from purpura?# scurvy, which may resemble the severe grade of purpura, has a different history, a recognizable cause, usually a peculiar distribution, and is accompanied with general weakness and a spongy, soft and bleeding condition of the gums. #what is the pathology of purpura?# the lesion of purpura consists essentially of a hemorrhage into the cutaneous tissues. the blood is subsequently absorbed, the hæmatin undergoing changes of color from a red to greenish and pale yellow, and finally fading away. #state the prognosis# the milder varieties disappear in the course of several weeks or months, and are rarely of serious import; the outcome of purpura hæmorrhagica is somewhat uncertain; although usually favorable, a fatal result from internal hemorrhage is possible. the variety known as schönlein's disease is alarming, but seldom fatal. henoch's disease is, however, always of grave import. #what is the treatment of purpura?# hygienic and dietary measures, the administration of tonics and astringents, and, in severe cases, by relative or absolute rest. the drugs commonly prescribed are: ergot, oil of erigeron, oil of turpentine, quinia, strychnia, iron, mineral acids, and gallic acid. _external_ treatment is rarely called for, but if deemed advisable, astringent lotions may be employed. #scorbutus.# (_synonyms:_ scurvy; sea scurvy; purpura scorbutica.) #describe scorbutus.# scurvy is a peculiar constitutional state, developed in those living under bad hygienic conditions, and is characterized by emaciation, general febrile and asthenic symptoms, a more or less swollen, turgid and spongy and even gangrenous condition of the gums; and concomitantly, or sooner or later, by the appearance, usually upon the lower portion of the legs only, of dark-colored hemorrhagic patches or blotches. the skin of the affected part may become brawny and slightly scaly, and not infrequently may break down and ulcerate. hemorrhages from the various mucous surfaces, slight or grave, may also take place. #state the etiology of scurvy.# it is due to long-continued deprivation of proper food, especially of fruits and vegetables. other bad hygienic conditions favor its development. it is seen most commonly in sailors and others taking long voyages. #how is scurvy to be distinguished from purpura?# by the asthenic and emaciated general condition and the peculiar puffy, spongy state of the gums. the cutaneous manifestation is more diffused, forming usually large palm-sized patches, and, as a rule, limited to the region of the ankles or lower part of the legs. #give the prognosis of scurvy.# the disease is remediable, and usually rapidly so. in those instances in which the same bad hygienic conditions and the ingestion of improper food are continued, death finally results. #what treatment would you advise in scurvy?# proper food, with an abundance of fruit and vegetables. lemon or lime juice is especially valuable, and is to be taken freely. if indicated, tonics and stimulants are also to be prescribed. for the relief of the tumid, spongy condition of the gums, astringent and antiseptic mouth washes are to be employed. the cutaneous manifestations, when tending to ulceration, are to be treated upon general principles. #class iv.--hypertrophies.# #lentigo.# (_synonym:_ freckle.) #describe lentigo.# lentigo, or freckle, is characterized by round or irregular, pin-head to pea-sized, yellowish, brownish or blackish spots, occurring usually about the face and the backs of the hands. it is a common affection, varying somewhat in the degree of development; the freckles present may be few and insignificant, or they may exist in profusion and be quite disfiguring. heat and exposure favor their development. those of light complexion, especially those with red hair, are its most common subjects. the color of the lesion is usually a yellowish-brown. it is common to all ages, but is generally seen in its greatest development during adolescence, the disposition to its appearance becoming less marked as age advances. #what is the pathology of lentigo?# lentigo consists simply of a circumscribed deposit of pigment granules--merely a localized increase of the normal pigment, differing from chloasma (_q. v._) only in the size and shape of the pigmentation. #state the prognosis.# the blemishes can be removed by treatment, but their return is almost certain. #name the several applications commonly employed for their removal.# an aqueous or alcoholic solution of corrosive sublimate, one-half to three grains to the ounce; lactic acid, one part to from six to twenty parts of water; and an ointment containing a drachm each of bismuth subnitrate and ammoniated mercury to the ounce. the applications, which act by removing the epidermal and rete cells and with them the pigment, are made two or three times daily, and their use intermitted for a few days as soon as the skin becomes irritated or scaly. touching each freckle for a few seconds with the electric needle, just pricking the epidermis, will occasionally remove the blemish. #chloasma.# #what do you understand by chloasma?# chloasma consists of an abnormal deposit of pigment, occurring as variously-sized and shaped, yellowish, brownish or blackish patches. #describe the clinical appearances of chloasma.# chloasma appears either in ill-defined patches, as is commonly the case, or as a diffuse discoloration. its appearance is rapid or gradual, generally the latter. the patches are rounded or irregular, and usually shade off into the sound skin. one, several or more may be present, and coalescence may take place, resulting in a large irregular pigmented area. the color is yellowish, or brownish, and may even be blackish (_melasma_, _melanoderma_). the skin is otherwise normal. the face is the most common site. #into what two general classes may the various examples of chloasma be grouped?# idiopathic and symptomatic. #what cases of chloasma are included in the idiopathic group?# all those cases of pigmentation caused by external agents, such as the sun's rays, sinapisms, blisters, continued cutaneous hyperæmia from scratching or any other cause, etc. #what cases of chloasma are included in the symptomatic group?# all forms of pigment deposit which occur as a consequence of various organic and systemic diseases, as the pigmentation, for instance, seen in association with tuberculosis, cancer, malaria, addison's disease, uterine affections, and the like. in such cases, with few exceptions, the pigmentation is usually more or less diffuse. #what is chloasma uterinum?# chloasma uterinum is a term applied to the ill-defined patches of yellowish-brown pigmentation appearing upon the faces of women, usually between the ages of twenty-five and fifty. it is most commonly seen during pregnancy, but may occur in connection with any functional or organic disease of the utero-ovarian apparatus. #what is argyria?# argyria is the term applied to the slate-like discoloration which follows the prolonged administration of silver nitrate. #state the pathology of chloasma.# the sole change consists in an increased deposit of pigment. #give the prognosis of chloasma.# unless a removal of the exciting or predisposing cause is possible, the prognosis is, as a rule, unfavorable, and the relief furnished by local applications usually but temporary. #if constitutional treatment is advisable, upon what is it to be based?# upon general principles; there are no special remedies. #how do external remedies act?# mainly by removing the rete cells and with them the pigmentation; and partly, also, by stimulating the absorbents. #are all external remedies which tend to remove the upper layers of the skin equally useful for this purpose?# no; on the contrary some such applications are followed by an increase in the pigment deposit. #name the several applications commonly employed.# corrosive sublimate in solution, in the strength of one to four grains to the ounce of alcohol and water; a lotion made up as follows:- [rx] hydrargyri chlorid. corros., ......... gr. iij-viij ac. acet. dilut., .................... f[dram]ij sodii borat., ........................ [scruple]ij aquæ rosæ, ........................... f[oz]iv. m. and also the following:- [rx] hydrargyri chlorid. corros., ......... gr. iij-viij zinci sulphat., plumbi acetat., ...... [=a][=a] ...... [dram]ss aquæ, ................................ f[oz]iv. m. and lactic acid, with from five to twenty parts of water; and an ointment containing a drachm each of bismuth subnitrate and white precipitate to the ounce. hydrogen peroxide occasionally acts well. trichloracetic acid, usually weakened with one or two parts water, may be cautiously tried. the application of a strong alcoholic solution of resorcin, twenty to fifty per cent. strength, is also valuable, as is also a two to ten per cent. alcoholic solution of salicylic acid. (applications are made two or three times daily, and as soon as slight scaliness or irritation is produced are to be discontinued for one or two days.) _tattoo-marks_ are difficult to remove. excision is the surest method. electrolysis, applying the needle at various points, somewhat close together, and using a fairly strong current--three to eight milliampères--will exceptionally, especially when repeated several times, produce a reactive inflammation and casting-off of the tissue containing the pigment; a scar is left. several writers claim good results with glycerole of papain, pricking it in in the same manner as in tattooing. _gun-powder marks._ if recent, but a day or so after their occurrence, the larger specks may be picked or scraped out. later, electrolysis, using a fairly strong current, may result in their removal. their removal may also be satisfactorily effected with a minute cutaneous trephine. #keratosis pilaris.# (_synonyms:_ pityriasis pilaris; lichen pilaris.) #what is meant by keratosis pilaris?# keratosis pilaris may be defined as a hypertrophic affection characterized by the formation of pin-head-sized, conical, epidermic elevations seated about the apertures of the hair follicles. #describe the clinical appearances of keratosis pilaris.# the lesions are usually limited to the extensor surfaces of the thighs and arms, especially the former. they appear as pin-head-sized, whitish or grayish elevations, consisting of accumulations of epithelial matter about the apertures of the hair follicles. each elevation is pierced by a hair, or the hair may be twisted and imprisoned within the epithelial mass; or it may be broken off just at the point of emergence at the apex of the papule, in which event it may be seen as a dark, central speck. the skin is usually dry, rough and harsh, and in marked cases, to the hand passing over it, feels not unlike a nutmeg-grater. the disease varies in its development, in most cases being so slight as to escape attention. as a rule, it is free from itching. #what course does keratosis pilaris pursue?# it is sluggish and chronic. #mention some of the etiological factors.# it is not an uncommon disease, and is seen usually in those who are unaccustomed to frequent bathing, being most frequently met with during the winter months. it is chiefly observed during early adult life. #is there any difficulty in the diagnosis?# no. it is thought at times to bear some resemblance to goose-flesh (cutis anserina), the miliary papular syphiloderm in its desquamating stage, and lichen scrofulosus. in goose-flesh the elevations are evanescent and of an entirely different character; the papules of the syphiloderm are usually generalized, of a reddish color, tend to group, are more solid and deeply-seated, less scaly and are accompanied with other symptoms of syphilis; in lichen scrofulosus the papules are larger, incline to occur in groups, and appear usually upon the abdomen. #state the prognosis.# the disease yields readily to treatment. #give the treatment of keratosis pilaris.# frequent warm baths, with the use of a toilet soap or sapo viridis, will usually be found curative. alkaline baths are also useful. in obstinate cases the ordinary mild ointments, glycerine, etc., are to be advised in conjunction with the baths. #keratosis follicularis.# #describe keratosis follicularis.# keratosis follicularis (_darier's disease_, _ichthyosis follicularis_, _ichthyosis sebacea cornea_, _psorospermosis_) is a rare disease characterized by pin-head to pea-sized pointed, rounded, or irregularly-shaped grayish, brownish, red or even black, horny papules or elevations, arising from the sebaceous or hair-follicles. they are, for the most part, discrete, with a tendency here and there to form solid aggregations or areas. many of them contain projecting cornified plugs which may be squeezed out, leaving pit-like depressions. the face, scalp, lower trunk, groins and flanks are the parts chiefly affected. the view advanced by darier, that the malady was due to psorosperms, is now denied, the bodies thought to be such having been demonstrated to be due to cell transformation. as to treatment, in one instance the induction of a substitutive dermatic inflammation had a favorable influence. #molluscum epitheliale.# (_synonyms:_ molluscum contagiosum; molluscum sebaceum; epithelioma molluscum.) #give a definition of molluscum epitheliale.# molluscum epitheliale is characterized by pin-head to pea-sized, rounded, semi-globular, or flattened, pearl-like elevations, of a whitish or pinkish color. #describe the symptoms and course of molluscum epitheliale.# the usual seat is the face; not infrequently, however, the growths occur on other parts. the lesions begin as pin-head, waxy-looking, rounded or acuminated elevations, gradually attaining the size of small peas. they have a broad base or occasionally may tend to become pedunculated. they rarely exist in profusion, in most cases three to ten or twelve lesions being present. when fully developed they are somewhat flattened and umbilicated, with a central, darkish point representing the mouth of the follicle. they are whitish or pinkish, and look not unlike drops of wax or pearl buttons. at first they are firm, but eventually, in most cases, tend to become soft and break down. not infrequently, however, the lesions disappear slowly by absorption, without apparent previous softening. their course is usually chronic. the contents, a cheesy-looking mass, may commonly be pressed out without difficulty. #what is the cause of molluscum epitheliale?# it is now generally accepted that the disease is mildly contagious. it occurs chiefly in children, and especially among the poorer classes. the belief in the parasitic nature of the disease is gaining ground; recently the opinion has been advanced that it is due to psorosperms (psorospermosis); but further investigations have indicated that these bodies were degenerated epithelia. #state the pathology.# [illustration: fig. 31. molluscum epitheliale.] according to recent investigations, molluscum epitheliale is to be regarded as a hyperplasia of the rete, the growth probably beginning in the hair-follicles; the so-called molluscum bodies--peculiar, rounded or ovoidal, sharply-defined, fatty-looking bodies found in microscopical examination of the growth--are to be viewed as a form of epithelial degeneration. #what are the diagnostic points in molluscum epitheliale?# the size of the lesions, their waxy or glistening appearance, and the presence of the central orifice. it is to be differentiated from molluscum fibrosum, warts and acne. #state the prognosis.# the growths are amenable to treatment. in some instances the disease, after existing some weeks, tends to disappear spontaneously. #what is the treatment of molluscum epitheliale?# incision and expression of the contents, and touching the base of the cavity with silver nitrate. pedunculated growths may be ligated. in some cases an ointment of ammoniated mercury, twenty to forty grains to the ounce, applied, by gently rubbing, once or twice daily, will bring about a cure. #callositas.# (_synonyms:_ tylosis; tyloma; callus; callous; callosity; keratoma.) #what do you understand by callositas?# a hard, thickened, horny patch made up of the corneous layers of the epidermis. #describe the clinical appearances.# callosities are most common about the hands and feet, and consist of small or large patches of dry, grayish-yellow looking, hard, slight or excessive epidermic accumulations. they are somewhat elevated, especially at the central portion, and gradually merge into the healthy skin. the natural surface lines are in a great measure obliterated, the patches usually being smooth and horn-like. _keratosis palmaris et plantaris_ (symmetric keratodermia), as regards the local condition, is a somewhat similar affection. it consists of hypertrophy of the corneous layer of the palm and soles, usually of a more or less horny and plate-like character, but is congenital or hereditary, and not necessarily dependent upon local friction or pressure. #are there any inflammatory symptoms in callositas?# no; but exceptionally, from accidental injury, the subjacent corium becomes inflamed, suppurates, and the thickened mass is cast off. #state the causes of callositas.# pressure and friction; for example, on the hands, from the use of various tools and implements, and on the feet from ill-fitting shoes. it is, indeed, often to be looked upon as an effort of nature to protect the more delicate corium. in exceptional instances it arises without apparent cause. #what is the pathology?# the epidermis alone is involved; it consists, in fact, of a hyperplasia of the horny layer. #state the prognosis of callositas.# if the causes are removed, the accumulation, as a rule, gradually disappears. the effect of treatment is always rapid and positive, but unless the etiological factors have ceased to act, the result is usually but temporary. #how is callositas treated?# when treatment is deemed advisable, it consists in softening the parts with hot-water soakings or poultices, and subsequently shaving or scraping off the callous mass. the same result may also be often effected by the continuous application, for several days or a week, of a 10 to 15 per cent. salicylated plaster, or the application of a salicylated collodion, same strength; it is followed up by hot-water soaking, the accumulation, as a rule, coming readily away. #clavus.# (_synonym:_ corn.) #what is clavus?# clavus, or corn, is a small, circumscribed, flattened, deep-seated, horny formation usually seated about the toes. #describe the clinical appearances.# ordinarily a corn has the appearance of a small callosity; the skin is thickened, polished and horny. exceptionally, however, occurring on parts that are naturally more or less moist, as between the toes, maceration takes place, and the result is the so-called _soft corn_. the dorsal aspect of the toes is the common site for the ordinary variety. the usual size is that of a small pea. they are painful on pressure, and, at times, spontaneously so. #state the causes.# corns are caused by pressure and friction, and may usually be referred to improperly fitting shoes. #what is the pathology of clavus?# it is a hypertrophy of the epiderm. its shape is conical, with the base external and the apex pressing upon the papillæ. it is, in fact, a peculiarly-shaped callosity, the central portion and apex being dense and horny, forming the so-called core. #give the treatment of clavus.# a simple method of treatment consists in shaving off, after a preliminary hot-water soaking, the outer portion, and then applying a ring of felt or like material, with the hollow part immediately over the site of the core; this should be worn for several weeks. it is also possible in some cases to extract the whole corn by gently dissecting it out; the after-treatment being the same as the above. another method is by means of a tento fifteen-per-cent. solution of salicylic acid, in alcohol or collodion, or the following:- [rx] ac. salicylici, ...................... gr. xxx ext. cannabis ind., .................. gr. x collodii, ............................ f[dram]iv. m. this is painted on the corn night and morning for several days, at the end of which time the parts are soaked in hot water, and the mass or a greater part of it, will be found, as a rule, to come readily away; one or two repetitions may be necessary. lactic acid, with one to several parts of water, applied once or twice daily, acts in a similar manner. soft corns, after the removal of pressure, may be treated with the solid stick of nitrate of silver, or by any of the methods already mentioned. in order that treatment be permanently successful, the feet are to be properly fitted. if pressure is removed, corns will commonly disappear spontaneously. #cornu cutaneum.# (_synonyms:_ cornu humanum; cutaneous horn.) #what is cornu cutaneum?# a cutaneous horn is a circumscribed hypertrophy of the epidermis, forming an outgrowth of horny consistence and of variable size and shape. #at what age and upon what parts are cutaneous horns observed?# they are usually met with late in life, and are mostly seated upon the face and scalp. [illustration: fig. 32. cutaneous horns. showing beginning epitheliomatous degeneration of the base. (_after pancoast._)] #describe the clinical appearances.# in appearance cutaneous horns resemble those seen in the lower animals, differing, if at all, but slightly. they are hard, solid, dry and somewhat brittle; usually tapering, and may be either straight, curved or crooked. their surface is rough, irregular, laminated or fissured, the ends pointed, blunt or clubbed. the color varies; it is usually grayish-yellow, but may be even blackish. as commonly seen they are small in size, a fraction of an inch or an inch or thereabouts in length, but exceptionally attain considerable proportions. the base, which rests directly upon the skin, may be broad, flattened, or concave, with the underlying and adjacent tissues normal or the papillæ hypertrophied; and in some cases there is more or less inflammation, which may be followed by suppuration. they are usually solitary formations. they are not, as a rule, painful, unless knocked or irritated. #what course do cutaneous horns pursue?# their growth is usually slow, and, after having attained a certain size, they not infrequently become loose and fall off; they are almost always reproduced. #what is the cause of these horny growths?# the cause is not known; appearing about the genitalia, they usually develop from acuminated warts. they are rare formations. #state the pathology of cornu cutaneum.# horns consist of closely agglutinated epidermic cells, forming small columns or rods; in the columns themselves the cells are arranged concentrically. in the base are found hypertrophic papillæ and some bloodvessels. they have their starting-point in the rete mucosum, either from that lying above the papillæ or that lining the follicles and glands. #does epitheliomatous degeneration of the base ever occur?# yes. #state the prognosis.# cutaneous horns may be readily and permanently removed. #what is the treatment?# treatment consists in detachment, and subsequent destruction of the base; the former is accomplished by dissecting the horn away from the base or forcibly breaking it off, the latter by means of any of the well-known caustics, such as caustic potash, chloride of zinc and the galvano-cautery. another method is to excise the base, the horn coming away with it; this necessitates, however, considerable loss of tissue. #verruca.# (_synonym:_ wart.) #what is verruca?# verruca, or wart, is a hard or soft, rounded, flat, acuminated or filiform, circumscribed epidermal and papillary growth. #name the several varieties of warts met with.# verruca vulgaris, verruca plana, verruca plana juvenilis, verruca digitata, verruca filifortnis and verruca acuminata. #describe verruca vulgaris.# this is the common wart, occurring mostly upon the hands. it is rounded, elevated, circumscribed, hard and horny, with a broad base, and usually the size of a pea. at first it is smooth and covered with slightly thickened epidermis, but later this disappears to some extent, the hypertrophied papillæ, appearing as minute elevations, making up the growth. one, several or more may be present. #describe verruca plana.# this is the so-called flat wart, and occurs commonly upon the back, especially in elderly people (_verruca senilis_, _keratosis pigmentosa_). it is, as a rule, but slightly elevated, is usually dark in color, and of the size of a pea or finger-nail. #describe verruca plana juvenilis.# the warts are mostly pin-head in size, flat, but slightly elevated, rounded, irregular or square-shaped, and of a light yellowish-brown color. they bear resemblance to lichen planus papules. they are apt to be numerous, often becoming aggregated or fused, and occur usually in young children, and, as a rule, on the face and hands. #describe verruca filiformis.# this is a thread-like growth about an eighth or fourth of an inch long, and occurring commonly about the face, eyelids and neck. it is usually soft to the touch and flexible. #describe verruca digitata.# this is a variety of wart, which, especially about the edges, is marked by digitations, extending nearly or quite down to the base. it is commonly seen upon the scalp. #describe verruca acuminata.# this variety (_venereal wart_, _pointed wart_, _pointed condyloma_), usually occurs about the genitalia, especially upon the mucous and muco-cutaneous surfaces. it consists of one or more groups of acuminated, pinkish or reddish, raspberry-like elevations, and, according to the region, may be dry or moist; if the latter, the secretion, which is usually yellowish and puriform, from rapid decomposition, develops an offensive and penetrating odor. the formation may be the size of a small pea, or may attain the dimensions of a fist. #what is the cause of warts?# the etiology is not known. they are more common in adolescent and early adult life. irritating secretions are thought to be causative in the acuminated variety. it is highly probable that a parasitic factor will finally be demonstrated. they are doubtless mildly contagious. [illustration: fig. 33. verruca acuminata--about the anus. (_after ashton._)] #state the pathology of warts.# a wart consists of both epidermic and papillary hypertrophy, the interior of the growth containing a vascular loop. in the acuminated variety there are marked papillary enlargement, excessive development of the mucous layer, and an abundant vascular supply. #give the treatment of warts.# for ordinary warts, excision or destruction by caustics. the repeated application of a saturated alcoholic solution of salicylic acid is often curative, the upper portion being pared off from time to time. the filiform and digitate varieties may be snipped off with the scissors, and the base touched with nitrate of silver; or a ligature may be used. curetting is a valuable operative method. the growths may also be removed by electrolysis. when warts are numerous and close together parasiticide applications can be daily made to the whole affected region. for this purpose a boric acid solution, containing five to thirty grains of resorcin to the ounce, and vleminckx's solution, at first diluted, prove the most valuable. verruca acuminata is to be treated by maintaining absolute cleanliness, and the application of such astringents as liquor plumbi subacetatis, tincture of iron, powdered alum and boric acid. the salicylic acid solution may also be used. in obstinate cases, glacial acetic acid or chromic acid may be cautiously employed. #nævus pigmentosus.# (_synonym:_ mole.) #describe nævus pigmentosus.# nævus pigmentosus, commonly known as mole, may be defined as a circumscribed increase in the pigment of the skin, usually associated with hypertrophy of one or all of the cutaneous structures, especially of the connective tissue and hair. it occurs singly or in numbers; is usually pea-, bean-sized or larger, rounded or irregular, smooth or rough, flat or elevated, and of a color varying from a light brown to black; the hair found thereon may be either colorless or deeply pigmented, coarse and of considerable length. it is, as a rule, a permanent formation. #name the several varieties of nævus pigmentosus met with.# nævus spilus, nævus pilosus, nævus verrucosus, and nævus lipomatodes. so-called linear nævus might also be considered as belonging in this group. #what is nævus spilus?# a smooth and flat nævus, consisting essentially of augmented pigmentation alone. [illustration: fig. 34. linear nævus.] #what is nævus pilosus?# a nævus upon which there is an abnormal growth of hair, slight or excessive. #what is nævus verrucosus?# a nævus to which is added hypertrophy of the papillæ, giving rise to a furrowed and uneven surface. #what is linear nævus?# linear nævus is a formation usually of a verrucous character, more or less pigmented, sometimes slightly scaly, occurring in band-like or zoster-like areas, and, as a rule, unilaterally. #what is nævus lipomatodes?# a nævus with excessive fat and connective-tissue hypertrophy. #state the etiology of nævus pigmentosus.# the causes are obscure. the growths are usually congenital; but the smooth, non-hairy moles may be acquired. #give the pathology of nævus pigmentosus.# microscopical examination shows a marked increase in the pigment in the lowest layers of the rete mucosum, as well as more or less pigmentation in the corium usually following the course of the bloodvessels; in the verrucous variety the papillæ are greatly hypertrophied, in addition to the increased pigmentation. there is, as a rule, more or less connective-tissue hypertrophy. #what is the treatment of nævus pigmentosus?# in many instances interference is scarcely called for, but when demanded consists in the removal of the formation either by the knife, by caustics, or by electrolysis. this last is, in the milder varieties at least, perhaps the best method, as it is less likely to be followed by disfiguring cicatrices. in nævus pilosus the removal of the hairs alone by electrolysis is not infrequently followed by a decided diminution of the pigmentation. in recent years both liquid air and carbon dioxide have also been used successfully in the removal of these growths. pigmented nævi, which show the least tendency to growth or degenerative change, should be radically removed, as they not infrequently lead to carcinomatous and sarcomatous growths. #ichthyosis.# (_synonym:_ fish-skin disease.) #give a descriptive definition of ichthyosis.# ichthyosis is a chronic, hypertrophic disease, characterized by dryness and scaliness of the skin, with a variable amount of papillary growth. #at what age is ichthyosis first observed?# it is first noticed in infancy or early childhood. in rare instances it is congenital (ichthyosis congenita), and in such cases it is usually severe, and of a grave type; the children are, as a rule, prematurely born, and frequently do not survive many days or weeks. #what extent of surface is involved?# usually the whole surface, but it is most marked upon the extensor surfaces of the arms and legs, especially at the elbows and knees; the face and scalp, in mild cases, often remain free. #name the two varieties of ichthyosis usually described.# ichthyosis simplex and ichthyosis hystrix, terms commonly employed to designate the mild and severe forms respectively. #describe the clinical appearances of ichthyosis.# the milder forms of the disease may be so slight as to give rise to simple dryness or harshness of the skin (_xeroderma_); but as commonly met with it is more developed, more or less marked scaliness in the form of thin or somewhat thick epidermal plates being present. the papillæ of the skin are often slightly hypertrophied. in slight cases the color of the scales is usually light and pearly; in the more marked examples it is dark gray, olive green or black. in the severe variety--ichthyosis hystrix--in addition to scaliness there is marked papillary hypertrophy, forming warty or spinous patches. this type is rare, and, as a rule, the surface involved is more or less limited. #are there any inflammatory symptoms in ichthyosis?# no. in fact, beyond the disfigurement, the disease causes no inconvenience; in those well-marked cases, however, in which the scales are thick and more or less immovable, the natural mobility of the parts is compromised and fissuring often occurs. in the winter months, in the severer cases, exposed parts may become slightly eczematous. #does ichthyosis vary somewhat with the season?# yes. in all cases the disease is better in the warm months, and in the mild forms may entirely disappear during this time. this favorable change is purely mechanical--due to the maceration to which the increased activity of the sweat glands gives rise. #is the general health affected in ichthyosis?# no. #what course does ichthyosis pursue?# chronic. beginning in early infancy or childhood, it usually becomes gradually more marked until adult age, after which time it, as a rule, remains stationary. #what is the etiology?# beyond a hereditary influence, which is often a positive factor, the causes are obscure. it is not a common disease. #state the pathology.# anatomically the essential feature is epidermic hypertrophy, with usually a varying degree of papillary hypertrophy also. #mention the diagnostic features of ichthyosis.# the harsh, dry skin, epidermic and papillary hypertrophy, the furfuraceous or plate-like scaliness, the greater development upon the extensor surfaces, a history of the affection dating from early childhood, and the absence of inflammatory symptoms. #how is ichthyosis to be distinguished from eczema, psoriasis, and other scaly inflammatory diseases?# by the absence of the inflammatory element. #what is the outlook for a case of ichthyosis?# the prognosis is unfavorable as regards a cure, but the process may usually be kept in abeyance or rendered endurable by proper measures. #what treatment would you prescribe for ichthyosis?# treatment that has in view removal of the scaliness and the maintenance of a soft and flexible condition of the skin. in mild cases frequent warm baths, simple or alkaline, will suffice; in others an application of an oily or fatty substance, such as the ordinary oils or ointments, made several hours or immediately before the bath may be necessary. in moderately developed cases the skin is to be washed energetically with sapo viridis and hot water, followed by a warm bath, after which an oily or fatty application is made. in some of the more severe cases the following plan is often useful: the parts are first rubbed with a soapy ointment consisting of one part of precipitated sulphur and seven parts of sapo viridis; a bath is then taken, the skin wiped dry, and a one to five per cent. ointment of salicylic acid gently rubbed in. glycerine lotions, one or two drachms to the ounce of water, are also beneficial; as also the following:- [rx] ac. salicylici, ...................... gr. x-xl glycerini, ........................... [dram]ss-[dram]j lanolin, petrolati, .................. [=a][=a] [oz]ss in severe cases of ichthyosis hystrix it may be necessary, also, to employ caustics or the knife. #what systemic treatment would you prescribe?# constitutional remedies are practically powerless; occasionally some good is accomplished by the internal administration of linseed oil and jaborandi. #onychauxis.# (_synonym:_ hypertrophy of the nail.) #describe onychauxis.# onychauxis, or hypertrophy of the nail, may take place in one or all directions, and this increase may be, and often is, accompanied by changes in shape, color, and direction of growth. one or all the nails may share in the process. as the result of lateral deviation of growth, the nail presses upon the surrounding tissues, producing a varying degree of inflammation--_paronychia_. #what is the etiology of hypertrophy of the nail?# the condition may be either congenital or acquired. in the latter instances it is usually the result of the extension to the matrix of such cutaneous diseases as psoriasis and eczema; or it is produced by constitutional maladies, such as syphilis. #give the treatment of hypertrophy of the nail.# treatment consists in the removal of the redundant nail-tissue by means of the knife or scissors; and, when dependent upon eczema or psoriasis, the employment of remedies suitable for these diseases. when it is the result of syphilis, the medication appropriate to this disease is to be employed. in paronychia the nail should be frequently trimmed and a pledget of lint or cotton be interposed between the edge of the nail and the adjacent soft parts; astringent powders and lotions may often be employed with advantage; and in severe and persistent cases excision of the nail, partial or complete, may be found necessary. #hypertrichosis.# (_synonyms:_ hirsuties; hypertrophy of the hair; superfluous hair.) #what is meant by hypertrichosis?# hypertrichosis is a term applied to excessive growth of hair, either as regards region, extent, age or sex. #describe the several conditions met with.# the unnatural hair growth may be slight, as, for instance, upon a nævus (_nævus pilosus_); or it may be excessive, as in the so-called hairy people (_homines pilosi_); or it may also appear on the face, arms and other parts in females, resulting from a hypertrophy of the natural lanugo hairs. #state the causes of hypertrichosis.# hereditary influence is often a factor; the condition may also be congenital. if acquired, the tendency manifests itself usually toward middle life. in women, it is not infrequently associated with diseases of the utero-ovarian system; in many instances, however, there is no apparent cause. local irritation or stimulation has at times a causative influence. #how is hypertrichosis to be treated?# for general hypertrichosis there is no remedy. small hairy nævi may be excised, or, as also in the larger hairy moles, the hairs may be removed by electrolysis. on the faces of women, if the hairs are coarse or large, electrolysis constitutes the only satisfactory method; if the hairs are small and lanugo-like, the operation is not to be advised. it is somewhat painful, but never unbearable. in the past several years the _x_-ray has been advocated by several writers, but it requires usually numerous exposures pushed to the point of producing erythema; it is not without risk, and the hairs are said to return in some months. #what temporary methods are usually resorted to for the removal of superfluous hair?# shaving, extraction of the hairs and the use of depilatories. as a depilatory, a powder made up of two drachms of barium sulphide and three drachms each of zinc oxide and starch, is commonly (and cautiously) employed; at the time of application enough water is added to the powder to make a paste, and it is then spread thinly upon the parts, allowed to remain five to fifteen minutes, or until heat of skin or a burning sensation is felt, washed off thoroughly, and a soothing ointment applied. this preparation must be well prepared to be efficient. #describe the method of removal of superfluous hair by electrolysis.# a fine needle in a suitable handle is attached to the _negative_ pole of a _galvanic_ battery, introduced into the hair-follicle to the depth of the papilla, and the circuit completed by the patient touching the positive electrode; in several seconds slight blanching and frothing usually appear at the point of insertion; a few seconds later the current is broken by release of the positive electrode, and the needle is then withdrawn. sometimes a wheal-like elevation arises, remains several minutes or hours, and then disappears; or occasionally, probably from secondary infection, it develops into a pustule. a strength of current of a half to two milliamperes is usually sufficient; the time necessary for the destruction of the papilla varying from several to thirty seconds. #how are you to know if the papilla has been destroyed?# the hair will readily come out with but little, if any, traction. #what is the result if the current has been too strong or too long continued?# the follicle suppurates and a scar results. #why should contiguous hairs not be operated upon at the same sitting?# in order that the chances of marked inflammatory action and scarring (always possibilities) may be reduced to a minimum. #in case of failure to destroy an individual papilla, should a second attempt be made at the same sitting?# as a rule not, in order to avoid the possibility of too much destructive action, and consequent scarring. #can scarring always be prevented?# in the average case, with skill and care, the use of an exceedingly fine needle and the avoidance of too strong a current, _perceptible_ scarring (scarring perceptible to the ordinary observer or at ordinary distance) need rarely occur. #what measures are to be advised for the irritation produced by the operation?# hot-water applications and the use of an ointment made of two drachms cold cream and ten grains of boric acid are of advantage not only in reducing the resulting hyperæmia, but also in preventing suppuration and consequent scarring. to lessen the chances of the latter, cleansing the parts with alcohol just before and after the operation is also of service. #[oe]dema neonatorum.# #describe [oe]dema neonatorum.# the essential symptoms are [oe]dema and a variable degree of hardness and induration. it develops in the first few days of life, and usually upon the extremities, especially the lower. it may remain more or less limited to these parts, but, as a rule, slowly extends. the skin is of a yellowish, dusky, or livid color, and sometimes glossy or shining. there are general symptoms of drowsiness, subnormal temperature, weakened circulation, and impaired respiration, which gradually increase, and in eighty to ninety per cent. of the cases lead to death. it is believed to be similar to anasarca in the adult and to be due to like causes. treatment consists in maintaining the body-heat, sufficient and proper nourishment and stimulation. #sclerema neonatorum.# (_synonyms:_ scleroderma neonatorum; sclerema of the newborn.) #what is sclerema neonatorum?# sclerema neonatorum is a disease of infancy, showing itself usually at or shortly after birth, and is characterized by a diffuse stiffness and rigidity of the integument, accompanied by coldness, [oe]dema, discoloration, lividity and general circulatory disturbance. #describe the symptoms, course, nature and treatment of sclerema neonatorum.# as a rule the disease first manifests itself upon the lower extremities, and then gradually, but usually rapidly, invades the trunk, arms and face. the surface is cold. the skin, which is noted to be reddish, purplish or mottled, is [oe]dematous, stiff and tense; in consequence the infant is unable to move, respires feebly and usually perishes in a few days or weeks. in extremely exceptional instances the disease, after involving a small part, may retrogress and recovery take place. the disease is rare, and in most cases is found associated with pneumonia and with affections of the circulatory apparatus. treatment should be directed toward maintaining warmth and proper alimentation. #scleroderma.# (_synonyms:_ sclerema; scleriasis; dermatosclerosis; morph[oe]a; keloid of addison.) #what is scleroderma?# scleroderma is an acute or chronic disease of the skin characterized by a localized or general, more or less diffuse, usually pigmented, rigid, stiffened, indurated or hide-bound condition. morph[oe]a, by some formerly thought to be a distinct affection, is now believed to be a form of scleroderma; as typically met with it is characterized by one or more rounded, oval, or elongate, cointo palm-sized, pinkish, or whitish ivory-looking patches. in some instances such patches are seen in association with the more classic type of scleroderma just defined. #describe the symptoms of ordinary scleroderma.# the disease may be acute or chronic, usually the latter. a portion or almost the entire surface may be involved, or it may occupy variously sized and shaped areas. the integument becomes more or less rigid and indurated, hard to the touch, hide-bound, and in marked cases immobile. [oe]dema may, especially in the more acute cases, precede the induration. pigmentation, of a yellowish or brownish color, is often a precursory and accompanying symptom. the skin feels tight and contracted, and in some instances numbness and cramp-like pains are complained of. #describe the variety known as morph[oe]a.# the patches (one, several, or more), occurring most frequently about the trunk, are in the beginning usually slightly hyperæmic, later becoming pale-yellowish or white, and having a pinkish or lilac border made up of minute capillaries. they are, as a rule, sharply defined, with a smooth, often shining and atrophic-looking surface; are soft, fine or leathery to the touch, on a level or somewhat depressed, and appearing not unlike a piece of bacon or ivory laid in the skin. occasionally the patches are noted to occur over nerve-tracts. the adjacent skin may be normal or there may be more or less yellowish or brownish mottling. the subjective symptoms of tingling, itching, numbness, and even pain, may or may not be present. #what is the course of the disease?# sooner or later, usually after months or years, the disease ends in resolution and recovery, or in marked atrophic changes, causing contraction and deformity. as a rule, the general health remains good. #state the causes of scleroderma.# the condition is to be considered as probably of neurotic origin. exposure and shock to the nervous system are to be looked upon as influential. it is a rare disease, observed usually in early adult or middle life, and is more frequent in women than in men. #what is the pathology?# in typical and advanced cases both the true skin and the subcutaneous connective tissue show a marked increase of connective tissue-element, with thickening and condensation of the fibers. #is there any difficulty in reaching a diagnosis in scleroderma?# as a rule, no. the characters--rigidity, stiffness, hardness, and hide-bound condition of the skin--are always distinctive. the peculiar appearance, the course and character of the patches, of morph[oe]a are quite distinctive. #give the prognosis of scleroderma.# it should always be guarded. in many instances recovery takes place, whilst in others the disease is rebellious, lasting indefinitely. the prognosis of the variety known as morph[oe]a is less unfavorable than general scleroderma, and recovery more frequent. #what is the treatment of scleroderma?# tonics, such as arsenic, quinia, nux vomica, and cod-liver oil; conjointly with the local employment of stimulating, oily or fatty applications, friction, and electricity. röntgen-ray treatment is often of value, more especially in the morph[oe]a type. #elephantiasis.# (_synonyms:_ elephantiasis arabum; pachydermia; barbadoes leg; elephant leg.) #give a descriptive definition of elephantiasis.# elephantiasis is a chronic hypertrophic disease of the skin and subcutaneous tissue characterized by enlargement and deformity, lymphangitis, swelling, [oe]dema, thickening, induration, pigmentation, and more or less papillary growth. [illustration: fig. 35. elephantiasis of moderate development.] #what parts are commonly involved in elephantiasis?# usually one or both legs; occasionally the genitalia; other parts are seldom affected. #describe the symptoms of elephantiasis.# the disease usually begins with recurrent (at intervals of months or years) erysipelatous inflammation, with swelling, pain, heat, redness and lymphangitis; after each attack the parts remain somewhat increased in size, although at first not noticeably so. after months or one or two years the enlargement or hypertrophy becomes conspicuous, the part is chronically swollen, [oe]dematous and hard; the skin is thickened, the normal lines and folds exaggerated, the papillæ enlarged and prominent, and with more or less fissuring and pigmentation. #what is the further course of the disease?# there is gradual increase in size, the parts in some instances reaching enormous proportions; the skin becomes rough and warty, eczematous inflammation is often superadded, and, sooner or later, ulcers, superficial or deep, form--which, together with the crusting and moderate scaliness, present a striking picture. there may be periods of comparative inactivity, or, after reaching a certain development, the disease may, for a time at least, remain stationary. #are there any subjective symptoms?# a variable degree of pain is often noted, especially marked during the inflammatory attacks. the general health is not involved. #state the cause of elephantiasis.# the etiology is obscure. the disease rarely occurs before puberty. it is most common in tropical countries, more especially among the poor and neglected. it is not hereditary, nor can it be said to be contagious. inflammation and obstruction of the lymphatics, probably due, according to late investigations, to the presence of large numbers of filaria (microscopic thread-worms) in the lymph channels and bloodvessels, is to be looked upon as the immediate cause. #what is the pathology?# all parts of the skin and subcutaneous connective-tissue are hypertrophied, the lymphatic glands are swollen, the lymph channels and bloodvessels enlarged, and there is more or less inflammation, with [oe]dema. secondarily, from pressure, atrophy and destruction of the skin-glands, and atrophic degeneration of the fat and muscles result. #what are the diagnostic characters of beginning elephantiasis?# recurrent erysipelatous inflammation, attended with gradual enlargement of the parts. the appearances, later in the course of the disease, are so characteristic that a mistake is scarcely possible. #give the prognosis of elephantiasis.# if the case comes under treatment in the first months of its development, the process may probably be checked or held in abeyance; when well established, rarely more than palliation is possible. #what is the treatment of elephantiasis?# the inflammatory attacks are to be treated on general principles. quinia, potassium iodide, iron and other tonics are occasionally useful; and, especially in the earlier stages, climatic change is often of value. between the inflammatory attacks the parts are to be rubbed with an ointment of iodine or mercury, together with galvanization of the involved part. in elephantiasis of the leg, a roller or rubber bandage, or the gum stocking, is to be worn; compression and ligation of the main artery, and even excision of the sciatic nerve, have all been employed, with more or less diminution in size as a result. in elephantiasis of the genitalia, if the disease is well advanced, excision or amputation of the parts is to be practised. eczematous inflammation, if present, is to be treated with the ordinary remedies. #dermatolysis.# (_synonym:_ cutis pendula.) #give a descriptive definition of dermatolysis.# dermatolysis is a rare disease, consisting of hypertrophy and looseness of the skin and subcutaneous connective tissue, with a tendency to hang in folds. #describe the symptoms and course of dermatolysis.# it may be congenital or acquired, and maybe limited to a small or large area, or develop simultaneously at several regions. all parts of the skin, including the follicles, glands and subcutaneous connective and areolar tissue, share in the hypertrophy; and this in exceptional instances may be so extensive that the integument hangs in folds. the enlargement of the follicles, natural folds and rugæ gives rise to an uneven surface, but the skin remains soft and pliable. there is also increased pigmentation, the integument becoming more or less brownish. #what course does dermatolysis pursue?# its development is slow and usually progressive. it gives rise to no further inconvenience than its weight and consequent discomfort. #give the etiology.# the etiology is obscure. it is considered by some authors as allied to molluscum fibrosum, and, in fact, as a manifestation of that disease, ordinary molluscum tumors sometimes being associated with it. it is not malignant. #what is the pathology?# the disease consists of a simple hypertrophy of all the skin structures and the subcutaneous connective tissue. #what is the treatment of dermatolysis?# excision when advisable and practicable. #class v.--atrophies.# #albinismus.# #what do you understand by albinismus?# congenital absence, either partial or complete, of the pigment normally present in the skin, hair and eyes. #describe complete albinismus.# in complete albinismus the skin of the entire body is white, the hair very fine, soft and white or whitish-yellow in color, the irides are colorless or light blue, and the pupils, owing to the absence of pigment in the choroid, are red; this absence of pigment in the eyes gives rise to photophobia and nystagmus. _albinos_--a term applied to such individuals--are commonly of feeble constitution, and may exhibit imperfect mental development. #describe partial albinismus.# partial albinismus is met with most frequently in the colored race. in this form of the affection the pigment is absent in one, several or more variously-sized patches; usually the hairs growing thereon are likewise colorless. #is there any structural change in the skin?# no. the functions of the skin are performed in a perfectly natural manner, and microscopical examination shows no departure from normal structure save the complete absence of pigment. #what is known in regard to the etiology?# nothing is known of the causes producing albinismus beyond the single fact that it is frequently hereditary. #does albinismus admit of treatment?# no; the condition is without remedy. #vitiligo.# (_synonyms:_ leucoderma; leucopathia.) #give a definition of vitiligo.# vitiligo may be defined as a disease involving the pigment of the skin alone, characterized by several or more progressive, milky-white patches surrounded by increased pigmentation. #describe the symptoms of vitiligo.# the disease may begin at one or more regions, the backs of the hands, trunk and face being favorite parts; its appearance is usually insidious, and the spots may not be especially noticeable until they are the size of a pea or larger. the patches grow slowly, are milky or dead white, smooth, non-elevated, and of rounded outline; the bordering skin is darker than normal, showing increased pigmentation. several contiguous spots may coalesce and form a large, irregularly-shaped patch. hair growing on the involved skin may or may not be blanched. there are no subjective symptoms. #what course does vitiligo pursue?# the course of the disease is slow, months and sometimes years elapsing before it reaches conspicuous development. it may after a time remain stationary, or, in rare instances, retrogress; as a rule, however, it is progressive. exceptionally, the greater part, or even the whole surface may eventually be involved. #give the etiology of vitiligo.# disturbed innervation is thought to be influential. the disease develops often without apparent cause. alopecia areata and morph[oe]a have been observed associated with it. [illustration: fig. 36. vitiligo.] #state the pathology of vitiligo.# the disease consists, anatomically, of both a diminution and increase of the pigment--the white patch resulting from the former, and the pigmented borders from the latter. there is no textural change, the skin in other respects being normal. #from what diseases is vitiligo to be differentiated?# from morph[oe]a and from the anæsthetic patches of leprosy. #in what respects do these diseases differ from vitiligo?# in morph[oe]a there is textural change, and in leprosy both textural change and constitutional or other symptoms. #what prognosis is to be given?# it should always be guarded, the disease in almost all cases being irresponsive to treatment. #what is the treatment of vitiligo?# the general health is to be looked after, and remedies directed especially toward the nervous system to be employed. arsenic, in small and continued doses, seems at times to have an influence; when there is lack of general tone it may be prescribed as follows:- [rx] liq. potassii arsenitis, ............. f[dram]j tinct. nucis vom., ................... f[dram]iij elix. calisayæ, ....... q. s. ad ..... f[oz]iv. m. sig.--f[dram]j t. d. suprarenal-gland preparations in moderate dosage long continued has appeared in a few instances to be of some benefit. when upon exposed parts, stimulation of the patches, with the view of producing hyperæmia and consequent pigment deposit; conjoined with suitable applications to the surrounding pigmented skin, with a view to lessen the coloration (see _treatment of chloasma_), will be of aid in rendering the disease less conspicuous. or the condition may be, in a measure, masked by staining the patches with walnut juice or similar pigment. #canities.# (_synonym:_ grayness of the hair.) #describe canities.# canities, or graying of the hair, may occur in localized areas or it may be more or less general; the blanching may be slight, scarcely amounting to slight grayness, or it may be complete. it is common to advancing years (_canities senilis_); it is seen also exceptionally in early life (_canities præmatura_). the condition is usually permanent. the loss of pigment takes place, as a rule, slowly, but several apparently authentic cases have been reported in which the change occurred in the course of a night or in a few days. #what is the etiology of canities?# the causes are obscure. heredity is usually an influential factor, and conditions which impair the general nutrition have at times an etiological bearing. intense anxiety, fright, and other profound nervous shock are looked upon as causative in sudden graying of the hair. #give the treatment.# canities is without remedy. dyeing, although not to be advised, is often practised, and the condition thus masked. #alopecia.# (_synonym:_ baldness.) #what do you understand by alopecia?# by alopecia is meant loss of hair, either partial or complete. #name the several varieties of alopecia.# the so-called varieties are based mainly upon the etiology, and are named congenital alopecia, premature alopecia and senile alopecia. #describe congenital alopecia.# congenital alopecia is a rare condition, in which the hair-loss is usually noted to be patchy, or the general hair-growth may simply be scanty. in rare instances the hair has been entirely wanting; in such cases there is usually defective development of other structures, such as the teeth. #describe premature alopecia.# loss of hair occurring in early and middle adult life is not uncommon, and may consist of a simple thinning or of more or less complete baldness of the whole or greater part of the scalp. it usually develops slowly, some months or several years passing before the condition is well established. it is often idiopathic, and without apparent cause further than probably a hereditary predisposition. it may also be symptomatic, as, for example, the loss of hair, usually rapid (_defluvium capillorum_), following systemic diseases, such as the various fevers, and syphilis; or as a result of a long-continued seborrh[oe]a or seborrh[oe]ic eczema (_alopecia furfuracea_). #describe senile alopecia.# this is the baldness so frequently seen developing with advancing years, and may consist merely of a general thinning, or, more commonly a general thinning with a more or less complete baldness of the temporal and anterior portion or of the vertex of the scalp. #what is the prognosis in the various varieties of alopecia?# in those cases in which there is a positive cause, as, for instance, in symptomatic alopecia, the prognosis is, as a rule, favorable, especially if no family predisposition exists. in the congenital and senile varieties the condition is usually irremediable. in idiopathic premature alopecia, the prognosis should be extremely guarded. #how would you treat alopecia?# by removing or modifying the predisposing factors by appropriate constitutional remedies, and by the external use of stimulating applications. #name several remedies or combinations usually employed in the local treatment.# sulphur ointment, full strength or weakened with lard or vaseline; a lotion of resorcin consisting of one or two drachms to four ounces of alcohol, to which is added ten to thirty minims of castor oil; and a lotion made up as follows:- [rx] tinct. cantharidis, .................. f[dram]iv tinct. capsici, ...................... f[oz]j ol. ricini, .......................... f[dram]ss-f[dram]j alcoholis, .... q. s. ad ............. f[oz]iv. m. the following is sometimes beneficial:- [rx] resorcin, ............................ gr. lxxx quininæ (alkaloid), .................. gr. xv ol. ricini, ..........................

(the application selected should be gently--not rubbing--applied daily or every second or third day, according to the case; if a lotion, moistening the parts with it; if an ointment, merely greasing the parts. shampooing every one to three weeks, according to circumstances.) #alopecia areata.# (_synonyms:_ area celsi; alopecia circumscripta.) #what do you understand by alopecia areata?# [illustration: fig. 37. alopecia areata.] alopecia areata is an affection of the hairy system, in which occur one or more circumscribed, round or oval patches of complete baldness unattended by any marked alteration in the skin. #upon what parts and at what age does the disease occur?# in the large majority of cases the disease is limited to the scalp; but it may invade other portions of the body, as the bearded region, eyebrows, eyelashes, and, in rare instances, the entire integument. it is most common between the ages of ten and forty. #describe the symptoms of alopecia areata.# the disease begins either suddenly, without premonitory symptoms, one or several patches being formed in a few hours; or, and as is more usually the case, several days or weeks elapse before the bald area or areas are sufficiently large to become noticeable. the patches continue to extend peripherally for a variable period, and then remain stationary, or several gradually coalesce and form a large, irregular area involving the entire or a greater portion of the scalp. the skin of the affected regions is smooth, faintly pink or milky white, and at first presents no departure from the normal; sooner or later, however, the follicles become less prominent, and slight atrophy or thinning may occur, the bald plaques being slightly depressed. [illustration: fig. 38. alopecia areata--complete hair loss.] occasionally, usually about the periphery and in the early stages, a few hair-stumps may be seen. #what course does alopecia areata pursue?# almost invariably chronic. after the lapse of a variable period the patches cease to extend, the hairs at the margins of the bald areas being firmly fixed in the follicles; sooner or later a fine, colorless lanugo or down shows itself, which may continue to grow until it is about a half-inch or so in length and then drop out; or it may remain, become coarser and pigmented, and the parts resume their normal condition. not infrequently, however, after growing for a time, the new hair falls out, and this may happen several times before the termination of the disease. #are there any subjective symptoms in alopecia areata?# as a rule, not; but occasionally the appearance of the patches is preceded by severe headache, itching or burning, or other manifestations of disturbed innervation. #state the cause of alopecia areata.# the etiology is obscure. two theories as to the cause of the disease exist: one of these regards it as parasitic, and the other considers it to be trophoneurotic. doubtless both are right, as a study of the literature would indicate that there are, as regards etiology, really two varieties--the contagious and the non-contagious. in america examples of the contagious variety are uncommon. #does the skin undergo any alterative or destructive changes?# microscopical examination of the skin of the diseased area shows little or no alteration in its structure beyond slight thinning. #how do you distinguish alopecia areata from ringworm?# the plaques of alopecia areata are smooth, often completely devoid of hair, and free from scales; while those of ringworm show numerous broken hairs and stumps, desquamation, and usually symptoms of mild inflammatory action. in doubtful cases recourse should be had to the microscope. #what is the prognosis in alopecia areata?# the disease is often rebellious, but in children and young adults the prognosis is almost invariably favorable, permanent loss of hair being uncommon. the same holds true, but to a much less extent, with the disease as occurring in those of more advanced age. in extensive cases--those in which the hair of the entire scalp finally entirely disappears, and sometimes involves all hairy parts--the prognosis is unfavorable. only exceptionally does recovery ensue in such instances. the uncertain duration, however, must be borne in mind; months, and in some instances several years, may elapse before complete restoration of hair takes place. relapses are not uncommon. #how is alopecia areata treated?# by both constitutional and local measures, the former having in view the invigoration of the nervous system, and the latter a stimulating and parasiticidal action of the affected areas. #give the constitutional treatment.# arsenic is perhaps the most valuable remedy, while quinine, nux vomica, pilocarpine, cod-liver oil and ferruginous tonics may, in suitable cases, often be administered with benefit. #name several remedies or combinations employed in the external treatment of alopecia areata.# ointments of tar and sulphur of varying strength; the various mercurial ointments; the tar oils, either pure or with alcohol; stimulating lotions, containing varying proportions, singly or in combination, of tincture of capsicum, tincture of cantharides, aqua ammoniæ, and oil of turpentine. the following is a safe formula, especially in dispensary and ignorant class practice: [rx] [beta]-naphthol, ..................... [dram]ss-[dram]j ol. cadini, .......................... [dram]j ungt. sulphuris, .......... q. s. ad ... [oz]j m. the cautious use of a five to twenty per cent. chrysarobin ointment is of value. painting the patches with pure carbolic acid or trikresol every ten days or two weeks sometimes acts well; it should not be applied over large areas nor used in young children. galvanization or faradization of the affected parts may also be employed, and with, occasionally, beneficial effect. stimulation with the high-frequency current by means of the vacuum electrode is also of value. when practicable, the finsen light can be applied with hope of benefit and cure. #atrophia pilorum propria.# (_synonym:_ atrophy of the hair.) #what do you understand by atrophy of the hair?# an atrophic, brittle, dry condition of the hair, and which may be either symptomatic or idiopathic. #describe the several conditions met with.# as a symptomatic affection, the dry, brittle condition of the hair met with in seborrh[oe]a, in severe constitutional diseases, and in the various vegetable parasitic affections, may be referred to. as an idiopathic disease it is rare, consisting simply of a brittleness and an uneven and irregular formation of the hair-shaft, with a tendency to split up into filaments (_fragilitas crinium_); or there may be localized swelling and bursting of the hair-shaft, the nodes thus produced having a shining, semi-transparent appearance (_trichorrhexis nodosa_). this latter usually occurs upon the beard and moustache. #state the causes of atrophy of the hair.# the causes of the symptomatic variety are usually evident; the etiology of idiopathic atrophy is obscure, but by many is thought due to parasitism. [illustration: fig. 39. trichorrhexis nodosa. (_after michelson._)] #what would be your prognosis and treatment in atrophy of the hair?# symptomatic atrophy usually responds to proper measures, but always slowly; treatment is based upon the etiological factors. for the idiopathic disease little, as a rule, can be done; repeated shaving or cutting the hair has, in exceptional instances, been followed by favorable results. #atrophia unguis.# (_synonyms:_ atrophy of the nails; onychatrophia.) #describe atrophy of the nails.# the nails are soft, thin and brittle, splitting easily, and are often opaque and lustreless, and may have a worm-eaten appearance. several or more are usually affected. #state the causes of atrophy of the nails.# the condition may be congenital or acquired, usually the latter. it may result from trauma, or be produced by certain cutaneous diseases, notably eczema and psoriasis; or it may follow injuries or diseases of the nerves. syphilis and chronic wasting constitutional diseases may also interfere with the normal growth of the nail-substance, producing varying degrees of atrophy. the fungi of tinea trichophytina and tinea favosa at times invade these structures and lead to more or less complete disintegration--_onychomycosis_. [illustration: fig. 40. atrophy of the nails.] #what is the treatment of atrophy of the nails?# treatment will depend upon the cause. when it is due to eczema or psoriasis, appropriate constitutional and local remedies should be prescribed. if it is the result of syphilis, mercury and potassium iodide are to be advised. in onychomycosis--an exceedingly obstinate affection--the nails should be kept closely cut and pared, and a oneto five-grain solution of corrosive sublimate applied several times a day; a lotion of sodium hyposulphite, a drachm to the ounce, is also a valuable and safe application. #atrophia cutis.# (_synonyms:_ atrophoderma; atrophy of the skin.) #what do you understand by atrophy of the skin?# by atrophy of the skin is meant an idiopathic or symptomatic wasting or degeneration of its component elements. #state the several conditions met with.# glossy skin, general idiopathic atrophy of the skin, parchment skin, atrophic lines and spots, senile atrophy, and the atrophy following certain cutaneous diseases. #describe glossy skin (atrophoderma neuriticum), and state the treatment.# glossy skin is a rare condition following an injury or disease of the nerve. it is usually seen about the fingers. the skin is hairless, faintly reddish, smooth and shining, with a varnished and thin appearance, and with a tendency to fissuring. more or less severe and persistent burning pain precedes and accompanies the atrophy. protective applications are called for, the disease tending slowly to spontaneous disappearance. #describe general idiopathic atrophy of the skin, and give the treatment.# general idiopathic atrophy of the skin is extremely rare, and is characterized by a gradual, more or less general, degenerative and quantitative atrophy of the skin structures, accompanied usually with more or less discoloration and pigmentation. treatment is palliative and based upon indications. #describe parchment skin, and state the treatment.# parchment skin (_xeroderma pigmentosum_, _angioma pigmentosum et atrophicum_) is a rare disease, the exact nature of which is not understood. it is characterized by the appearance of numerous disseminated, freckle-like pigment-spots, telangiectases, atrophied muscles, more or less shrinking and contraction of the integument, and followed, in most instances, by epitheliomatous tumors and ulceration, and finally death. it is usually slow in its course, beginning in childhood and lasting for years. it is not infrequently seen in several children of the same family. treatment is palliative, consisting, if necessary, of the use of protective applications and of the administration of tonics and nutrients. #describe atrophic lines and spots.# atrophic lines and spots (_striæ et maculæ atrophicæ_) may be idiopathic or symptomatic, the lesions consisting of scar-like or atrophic-looking, whitish lines and macules, most commonly seen on the trunk. they are smooth and glistening. slight hyperæmia usually precedes their formation. as an idiopathic disease its course is insidious and slow, and its progress eventually stayed. the so-called _lineæ albicantes_, resulting from the stretching of the skin produced by pregnancy or tumors, and from rapid development of fat, may be mentioned as illustrating the symptomatic variety. in course of time the atrophy becomes less conspicuous. #describe senile atrophy.# senile atrophy is not uncommon, the atrophy resulting, as the name inferentially implies, from advancing age. it is characterized by thinning and wasting, dryness, and a wrinkled condition, with more or less pigmentation and loss of hair. circumscribed pigmentary deposits and seborrh[oe]a, with degeneration, are also noted. #what several diseases of the skin are commonly followed by atrophic changes?# favus, lupus, syphilis, leprosy, scleroderma and morph[oe]a. #class vi.--new growths.# #keloid.# (_synonyms:_ keloid of alibert; cheloid.) #give a descriptive definition of keloid.# keloid is a fibro-cellular new growth of the corium appearing as one or several variously-sized, irregularly-shaped, elevated, smooth, firm, pinkish or pale-reddish cicatriform lesions. #describe the clinical appearance of keloid.# the growth begins as a small, hard, elevated, pinkish or reddish tubercle, increasing gradually, several months or years usually elapsing before the tumor reaches conspicuous size. when developed, it is one or more inches in diameter, is sharply defined, elevated, hard, rounded or oval, fungoid or crab-shaped, and firmly implanted in the skin. it is usually pinkish, pearl-white, or reddish, commonly devoid of hair, with no tendency to scaliness, and with, usually, several vessels coursing over it. in some instances it is tender, and it may be spontaneously painful. the breast, especially over the sternal region, is a favorite site for its appearance. one, several or more may be present in the single case. #what course does keloid pursue?# chronic; usually lasting throughout life. in rare instances spontaneous involution takes place. #state the etiology of keloid.# the causes are obscure. the growth usually takes its start from some injury or lesion of continuity; for instance, at the site of burns, cuts, acne and smallpox scars, etc.--_cicatricial keloid, false keloid_; or it may also, so it is thought, originate in normal skin--_spontaneous keloid, true keloid_. #what is the pathology of keloid?# the lesion is a connective-tissue new growth having its seat in the corium. #is there any difficulty in the diagnosis of keloid?# no. it resembles hypertrophic scar; but this latter, which is essentially keloidal, never extends beyond the line of injury. #give the prognosis.# the growth is persistent and usually irresponsive to treatment. in some cases, however, there is eventually a tendency to spontaneous retrogression, up to a certain point at least. #what is the treatment of keloid?# usually palliative, consisting of the continuous application of an ointment such as the following:- [rx] acidi salicylici, .................... gr. x-xx emplast. plumbi, emplast. saponis, ... [=a][=a] ....... [dram]iij petrolati, ........................... [dram]ij. m. an ointment of ichthyol, twenty-five per cent. strength, rubbed in once or twice daily, is sometimes beneficial. operative measures, such as punctate and linear scarification, electrolysis and excision, are occasionally practised, but the results are rarely satisfactory and permanent; not infrequently, indeed, renewed activity in the progress of the growth is noted to follow. the _x_-ray can be tried with some hope of improvement. the administration of thyroid has been thought to have a possible influence in some instances. #fibroma.# (_synonyms:_ molluscum fibrosum; fibroma molluscum.) #what do you understand by fibroma?# fibroma is a connective-tissue new growth characterized by one or more sessile or pedunculated, peato egg-sized or larger, soft or firm, rounded, painless tumors, seated beneath and in the skin. #describe the clinical appearances of fibroma.# the growth may be single, in which case it is apt to be pedunculated or pendulous, and attain considerable dimensions; as a result of weight or pressure surface-ulceration may occur. or, as commonly met with, the lesions are numerous, scattered over large surface, and vary in size from a pea to a cherry; the overlying skin being normal, pinkish or reddish, loose, stretched, hypertrophied or atrophied. the tumors are painless. the general health is not involved. [illustration: fig. 41. fibroma. (_after octerlony._)] #what is the course of fibroma?# chronic and persistent. #what is the etiology of fibroma?# the cause is not known. heredity is often noted. the affection is not common. #state the pathology of fibroma.# the growths are variously thought to have their origin in the connective tissue of the corium, or in that of the walls of the hair-sac, or in the connective-tissue framework of the fatty tissue. recent tumors are composed of gelatinous, newly-formed connective tissue, and the older growths of a dense, firmly-packed, fibrous tissue. #from what growths is fibroma to be differentiated?# from molluscum contagiosum, neuroma and lipoma; the first is differentiated by its central aperture or depression, neuroma by its painfulness, and lipoma by its lobulated character and soft feel. #give the prognosis of fibroma.# the disease is persistent, and irresponsive to all treatment save operative measures. #what is the treatment of fibroma?# treatment consists, when desired and practicable, in the removal of the growths by the knife, or in large and pedunculated tumors by the ligature or by the galvano-cautery. #neuroma.# #describe neuroma.# neuroma of the skin is an exceedingly rare disease, characterized by the formation of variously-sized, usually numerous, firm, immovable and elastic fibrous tubercles containing new nerve-elements, and accompanied by violent, paroxysmal pain. their growth is slow and usually progressive. later they are painful upon pressure. they are limited to one region. the tumors are seated in the corium, extending into the deeper structure, and consist of nerve-fibres, yellow elastic tissue, blood vessels and lymphoid cells. in the two cases reported, excision of the nerve-trunk gave, in one instance, permanent relief; in the other the effect was only temporary. #xanthoma.# (_synonyms:_ vitiligoidea; xanthelasma.) #what is xanthoma?# xanthoma is a connective-tissue new growth characterized by the formation of yellowish, circumscribed, irregularly-shaped, variously-sized, non-indurated, flat or raised patches or tubercles. #name the two varieties met with.# the macular or flat (_xanthoma planum_) and the tubercular (_xanthoma tuberculatum_ or _tuberosum_). in some instances both varieties (_xanthoma multiplex_) are seen in the same individual. #describe the clinical appearances of xanthoma planum.# the macular or flat variety is usually seen about the eyelids. it consists of one, several or more small or large, smooth, opaque, sharply-defined, often slightly raised, yellowish patches, looking not unlike pieces of chamois-skin implanted in the skin. #describe the clinical appearances of xanthoma tuberosum.# the tubercular variety is commonly met with upon the neck, trunk and extremities. it occurs as small, raised, isolated, yellowish nodules, or as patches made up of aggregations of millet-seed-sized or larger tubercles. the lesions may be few or they may exist in great numbers. #what is the course of xanthoma?# extremely slow; after reaching a certain development the growths may remain stationary. #state the etiology of xanthoma.# the causes are obscure. jaundice not infrequently precedes and accompanies its development, especially in the tubercular variety. the disease is uncommon, and is usually seen in middle and advanced life, and more frequently in women. in some cases (_xanthoma diabeticorum_) of general xanthoma diabetes is the causative factor. #what is the pathology of xanthoma?# it is a benign, connective-tissue new growth, with concomitant or subsequent, but usually partial, fatty degeneration. #give the prognosis of xanthoma.# the condition is persistent, and usually irresponsive to all treatment save destructive or operative measures. #what is the treatment of xanthoma?# treatment consists, in suitable cases, of excision; in some instances, electrolysis is serviceable. applications of trichloracetic acid cautiously made are sometimes of value. in that form of general xanthoma due to diabetes the treatment of this latter condition will materially and sometimes completely remove the eruption. #myoma.# (_synonyms:_ myoma cutis; dermatomyoma; liomyoma cutis.) #describe myoma.# the disease is rare, and consists usually of one or several (exceptionally numerous), variously-sized tumors of the skin, made up of smooth muscular fibres. they are flat, rounded, oval or pedunculated, and have a smooth surface and a pale-red color; as a rule, they are painless. the growth is benign, and consists essentially of a new formation of unstriped muscular fibres; but it may also be composed largely of connective tissue (_fibromyoma_); or it may contain an abundance of bloodvessels (_myoma telangiectodes_, _angiomyoma_); or there may be lymphatic involvement (_lymphangiomyoma_). #angioma.# (_synonyms:_ nævus vasculosus; nævus sanguineus.) #give a definition of angioma.# angioma is a congenital hypertrophy of the vascular tissues of the corium and subcutaneous tissue. exceptionally it makes its appearance a few weeks or a month after birth. #into what two classes may angiomata be roughly grouped?# the flat (or non-elevated) and the prominent (or elevated). #describe the flat, or non-elevated, variety of angioma.# the flat, or non-elevated, angioma (_nævus flammeus_, _nævus simplex_, _angioma simplex_, _capillary nævus_) may be pin-headto bean-sized; or it may involve an area of several inches in diameter, and, exceptionally, a whole region. it is of a brightor dark-red color, and is met with most frequently about the face. in some instances it extends after birth, reaches a certain size and then remains stationary; occasionally, when involving a small area, it undergoes involution and disappears. the so-called _port-wine mark_ is included in this group. #describe the prominent, or elevated, variety of angioma.# the prominent variety (_venous n[oe]vus_, _angioma cavernosum_, _n[oe]vus tuberosus_) is variously-sized, often considerably elevated, clearly-defined, compressible, smooth or lobulated, and of a dark, purple color; it may, also, be erectile and pulsating. the growth is usually a single formation, and is met with upon all parts of the body. #what is the pathology of angioma?# it is a new growth, consisting of a variable hypertrophy of the cutaneous and subcutaneous arterial and venous bloodvessels, with or without an increase of the connective tissue. #give the treatment of angioma.# in some instances, especially in infants, painting the parts repeatedly with collodion or liquor plumbi subacetatis will act favorably. for well-established, small, capillary nævi electrolysis or puncturing with a red-hot needle or with a needle charged with nitric acid may be employed; for "port-wine mark" frequent and closely contiguous electrolytic punctures are occasionally followed by a slight diminution in color. for the _prominent growths_, vaccination, the ligature, puncturing with the galvano-cautery, and excision are variously resorted to. in recent years applications of liquid air and carbon dioxide have proved of service in some cases. #telangiectasis.# #describe telangiectasis.# telangiectasis consists of a new growth or enlargement of the cutaneous capillaries, usually appearing during middle adult life, and seated, for the most part, about the face. #to what extent may telangiectasis develop?# it may be limited to a red dot or point, with several small radiating capillaries (_nævus araneus_, _spider nævus_), or a whole region, usually the face, may show numerous scattered or closely-set capillary enlargements or new formations (_rosacea_). the latter is frequently associated with acne (_acne rosacea_). the etiology is obscure. #what is the treatment of telangiectasis?# destruction of the vessels by electrolysis or by the knife. (see treatment of acne rosacea.) #lymphangioma.# (_synonym:_ lymphangiectodes.) #describe lymphangioma.# lymphangioma is a rare disease, consisting of localized dilatations of the lymphatic vessels, appearing as discrete or aggregated pin-head or pea-sized, compressible, hollow, tubercle-like elevations, of a pinkish or faint lilac color, and occurring for the most part about the trunk. it is of slow but usually progressive development, and is unaccompanied by subjective symptoms. a rare condition, kaposi described as lymphangioma tuberosum multiplex, characterized by more or less solid, somewhat cystic, pearly to pinkish red, sometimes crowded lesions, is now known to be "benign cystic epithelioma"; its most common site is the face. while called "benign," ulcerative action may eventually ensue. treatment, when demanded, consists of operative measures. #rhinoscleroma.# #describe rhinoscleroma.# rhinoscleroma is a rare and obscure disease, slow but progressive in its course, characterized by the development of an irregular, dense and hard, flattened, tubercular, non-ulcerating, cellular new growth, having its seat about the nose and contiguous parts. the overlying skin is normal in color, or it may be lightor dark-brown or reddish. marked disfigurement and closure, partial or complete, of the nasal orifices gradually results. it is met with chiefly in austria and germany. treatment, consisting of partial or complete extirpation, is rarely permanent in its results, the disease tending to recur. #lupus erythematosus.# (_synonyms:_ lupus erythematodes; lupus sebaceus; seborrh[oe]a congestiva.) #what is lupus erythematosus?# lupus erythematosus may be roughly defined as a mildly to moderately inflammatory superficial new-growth formation, characterized by one, several, or more circumscribed, variously sized and shaped, pinkish or dark red patches, covered slightly, and more or less irregularly, with adherent grayish or yellowish scales. #upon what parts is lupus erythematosus observed?# its common site is the face, usually the nose and cheeks, with a tendency toward symmetry; it is often limited to these parts, but may occasionally be seen upon other regions, more especially the lips, ears, and scalp. in rare instances a great part of the general surface may become involved. #describe the symptoms of lupus erythematosus.# usually the disease begins as one or several rounded, circumscribed, pin-headto pea-sized lesions; slightly scaly, somewhat elevated, and of a pinkish, reddish or violaceous color. they slowly, or somewhat rapidly, increase in area, and after attaining variable size remain stationary; or they may progress and coalesce, and in this manner sooner or later involve considerable surface. the patches are sharply defined against the sound skin by an elevated border, while the central portion is somewhat depressed and usually atrophic. more or less thickening and infiltration are observed. _there is no tendency to ulceration_. the scaliness is, as a rule, scanty. the gland-ducts are enlarged, patulous or plugged with sebaceous and epithelial matter. the subjective symptoms of burning and itching are usually slight and often wanting. #what course does lupus erythematosus pursue?# as a rule, the disease is persistent, although somewhat variable. at times the patches retrogress, involution taking place with or without slight sieve-like atrophy or scarring. #state the causes of lupus erythematosus.# the etiology is obscure. some observers believe it to be a variety of cutaneous tuberculosis. it is essentially a disease of adult and middle age; is more common in women, and more frequent in those having a tendency to disorders of the sebaceous glands. it may, in fact, begin as a seborrh[oe]a. #what is the pathology?# it was formerly considered a new growth, but recent opinion tends toward regarding it as a chronic inflammation of the cutis, superinducing degenerative and atrophic changes. variable [oe]dema of the prickle layer and of the cutis is found. there is no tendency to pus formation. [illustration: fig. 42. lupus erythematosus.] #is there any difficulty in the diagnosis of lupus erythematosus?# as a rule, not, as the features of the disease--the sharply circumscribed outline, the reddish or violaceous color, the elevated border, the tendency to central depression and atrophy, the plugged up or patulous sebaceous ducts, the adherent grayish or yellowish scales, together with the region attacked (usually the nose and cheeks)--are characteristic. #state the prognosis of lupus erythematosus.# the disease is often capricious and extremely rebellious to treatment; some cases, up to a certain point at least, yield readily, and occasionally a tendency to spontaneous disappearance is observed; a complete cure is, however, it must be confessed, rather rare. the disease in nowise compromises the general health. in those rare instances of generalized disease the patient has usually died from an intercurrent tuberculosis. #how is lupus erythematosus to be treated?# the general health is to be looked after and systemic treatment prescribed, if indicated. as a rule, constitutional remedies exert little, if any, influence, but exceptionally, cod-liver oil, arsenic, phosphorus, salicin, quinine, or potassium iodide proves of service. locally, according to the case, soothing remedies, stimulating applications and destruction of the growth by caustics or operative measures are to be employed. (_try the milder applications first._) #mention the stimulating applications commonly employed.# washing the parts energetically with tincture of sapo viridis, rinsing and applying a soothing ointment, such as cold cream or vaseline. a lotion containing zinc sulphate and potassium sulphuret thoroughly dabbed on the parts morning and evening:- [rx] zinci sulphatis, potassii sulphurati, .... [=a][=a] ... [dram]i-[dram]iv glycerinæ, ........................... [minim]iv aquæ, ................................ f[oz]iv. m. the calamine-and-zinc oxide lotion used in acute eczema is also often extremely valuable. lotions of ichthyol and of resorcin, five to sixty grains to the ounce; ichthyol in ointment, fiveto twenty-per-cent. strength, is also useful. painting the patches with pure carbolic acid; repeating a day or two after the crusts have fallen off. the continuous application of mercurial plaster. sulphur and tar ointments, officinal strength or weakened with lard, and also the following:- [rx] ol. cadini, alcoholis, saponis viridis, ..... [=a][=a] ...... [dram]iiss. m. (this is to be rubbed in, in small quantity, once or twice daily, and later a soothing remedy applied.) in recent years both the _x_-ray and finsen light have been used with variable success. repeated applications of the high-frequency current, with the vacuum electrode, have also proved serviceable. cautious applications of liquid air or carbon dioxide have also been used with some success in the past few years. #when are destructive and operative measures justifiable?# in obstinate, sluggish, and long-persistent patches, and then only after other methods of treatment have failed. (remember that a patch or patches of the disease _may_ disappear in course of time spontaneously, and occasionally _without leaving a scar_.) #state the methods of treatment commonly used in obstinate, sluggish and persistent patches of lupus erythematosus.# cauterization--with nitrate of silver, with applications of pyrogallic acid in ointment or in liquor gutta-perchæ, fifteen to thirty per cent. strength, and with solutions (cautiously employed) of caustic potash, and exceptionally with the galvano-cautery. [illustration: fig. 43. single scarifier.] [illustration: fig. 44. multiple scarifier. (_as modified by van harlingen._)] operative--scarification, either punctate or linear, and erosion with the curette. (see treatment of lupus vulgaris.) #lupus vulgaris.# (_synonyms:_ lupus; lupus exedens; lupus vorax; tuberculosis of the skin.) #what do you understand by lupus vulgaris?# lupus vulgaris is a cellular new growth, characterized by variously-sized, soft, reddish-brown, papular, tubercular and infiltrated patches, usually terminating in ulceration and scarring. #upon what region is lupus vulgaris usually observed?# the face, especially the nose, but any part may be invaded. the area involved may be small or quite extensive, usually the former. #at what age is the disease noted?# in many cases it begins in childhood or early adult life, but as it is persistent and tends to relapse, it may be met with at any age. #describe the earlier symptoms of lupus vulgaris.# the disease begins by the development of several or more pin-head to small pea-sized, deep-seated, brownish-red or yellowish tubercles, having their seat in the deeper part of the corium, and which are somewhat softer and looser in texture than normal tissue. as the disease progresses, variously-sized and shaped aggregations or patches result, covered with thin and imperfectly-formed epidermis. #what changes do the lupus tubercles or infiltrations undergo?# the lesions, having attained a certain size or development, may remain so for a time, but sooner or later retrogressive changes occur: the matured papules or tubercles, or infiltrated patches, slowly disappear by absorption, fatty degeneration, and exfoliation, leaving a yellowish or brownish pigmentation, usually with more or less atrophy or cicatricial-tissue formation--_lupus exfoliativus_; or disintegration and destruction result, terminating in ulceration--_lupus exedens, lupus exulcerans_. this latter is the more usual course. #describe the clinical appearances and behavior of the lupus ulcerations.# they are rounded, shallow excavations, with soft and reddish borders. in exceptional instances exuberant granulations appear--_lupus hypertrophicus_; or papillary outgrowths are noted--_lupus verrucosus_. the ulcerations secrete a variable amount of pus, usually slight in quantity, which leads to more or less crust formation; later, however, cicatricial tissue, generally of a _firm and fibrous_ character, results. [illustration: fig. 45. lupus of arm.] #in what manner does the disease spread?# the patches spread by the appearance of new tubercles, or infiltrations at the peripheral portion. new islets and areas of disease may continue to make their appearance from time to time, usually upon contiguous parts. #are the mucous membranes of the mouth, throat and larynx ever involved?# in some instances, and either primarily or secondarily. [illustration: lupus vulgaris.] [illustration: lupus vulgaris.] #is the bone tissue ever involved in lupus vulgaris?# no. #what course does lupus vulgaris pursue?# it is slowly but, as a rule, steadily progressive. several years or more may elapse before the area of disease is conspicuous. #what is the cause of lupus vulgaris?# it is now known to be due to the invasion of the cutaneous structures by the tubercle bacillus; in short, a tuberculosis of the skin. it is not infrequently observed in the strumous and debilitated. it is entirely independent of syphilis. #what is the pathology of lupus vulgaris?# according to recent investigations, the infiltrations of lupus are due chiefly to cell-proliferation and outgrowth from the protoplasmic walls and adventitia of the bloodvessels and lymphatics. the fibrous-tissue network, vessels and a portion of the cell infiltration are thus produced, the fixed and wandering connective-tissue cells of the inflamed stroma of the cutis being responsible for the other portion of the new growth (robinson). #state the diagnostic features of lupus vulgaris.# in a typical, developed patch of lupus are to be seen:--cicatricial formation, usually of a fibrous and tough character; ulcerations; the yellowish-brown tubercles and infiltration; and the characteristic soft, small, yellowish or reddish-brown, cutaneous and subcutaneous points and tubercles. #how does the tubercular syphiloderm differ from lupus vulgaris?# the tubercular syphiloderm is much more rapid in its course, the ulceration is deeper and the discharge copious and often offensive; the scarring is soft, and, compared to the amount of ulceration, but slightly disfiguring; and it is, for obvious reasons, a disease of adult or late life. the history, together with other evidences of previous or concomitant symptoms of syphilis, will often aid in the differentiation. #how does epithelioma differ from lupus vulgaris?# the edges of the epitheliomatous ulcer are hard, elevated and waxy; the base is uneven, the secretion thin, scanty and apt to be streaked with blood; the ulceration usually starts from one point, and is often painful; the tissue destruction may be considerable; there is little, if any, tendency to the formation of cicatricial tissue; and, finally, it is usually a disease of advanced age. #in what respects does lupus erythematosus differ from lupus vulgaris?# lupus erythematosus has no papules, tubercles or ulceration. #how does acne rosacea differ from lupus vulgaris?# acne rosacea is characterized by hyperæmia, dilated vessels, papules, pustules, the absence of ulceration, and a different history. #state the prognosis of lupus vulgaris.# lupus vulgaris is always a chronic disease, often exceedingly rebellious to treatment, and one that calls for a guarded opinion. relapses are not uncommon. [illustration: fig. 46. galvano-cautery needle, knife and spiral points. (_as devised by bésnier._)] the general health usually remains good, but in some instances death by tuberculosis of the lungs has been noted. #is external or internal treatment called for in lupus vulgaris?# always external, and not infrequently constitutional also. #what is the constitutional treatment?# the general health must be cared for; good, nutritious food, fresh air and out-door exercise, together with, in many cases, the administration of such remedies as cod-liver oil, potassium iodide, iron and quinine, are of therapeutic importance. tuberculin may be tried in severe and obstinate cases, but its use is not without danger. #state the object of local treatment.# the destruction or removal of the diseased tissue. #may milder methods of treatment sometimes prove beneficial and even curative?# exceptionally, mercurial plaster, corrosive-sublimate lotion and ointment (gr. j to [oz]j), a plaster containing five to fifteen per cent. of salicylic acid and creasote, repeated paintings with carbolic acid, and the constant application of lead plaster containing twenty per cent. of ichthyol, are valuable. [illustration: fig. 47. double curette.] of the milder methods, those most in vogue to-day are the _finsen light_ and _x-ray_. either proves extremely valuable in some cases, but the finsen method is the favorite method. #what methods are commonly employed for the rapid removal or destruction of lupus tissue?# cauterization, scarification, erasion and excision are variously practised; the particular method depending, in great measure, upon the extent of the disease, the part involved, and other circumstances. #name the several caustics, and state how they are employed.# _pyrogallic acid_, used as an ointment:- [rx] ac. pyrogallici, ..................... [dram]ij emplast. plumbi, ..................... [dram]j cerat. resinsæ, ...................... [dram]v. m. it is applied for one or two weeks. every several days the parts are poulticed, the slough thus removed, and the ointment reapplied, and so on until the diseased tissue has been destroyed. it is useful in those cases in which a mild and comparatively painless caustic is advisable. in most cases several repetitions of this plan are necessary. _arsenious acid_, employed as an ointment- [rx] ac. arseniosi, ...................... gr. xx hydrarg. sulphid. rub., ............. gr. lx ungt. aquæ rosæ, .................... [oz]i.--m. it is painful but thorough; it is spread on lint and renewed daily. the action is usually sufficient in three days, and the parts are then poulticed until the slough comes away, after which a simple dressing is employed. its application is advisable for a small area only--not more than four square inches--as absorption is possible. _galvano-cautery._--the diseased tissue is destroyed by numerous punctures with a red-heated point or by linear incision with a red-heated knife. it is often a practicable and satisfactory method. the paquelin cautery and liquid air and carbon dioxide also have their advocates. #describe the operative measures employed in the removal of lupus tissue.# _linear scarification._--the parts are thoroughly cross-tracked, cutting through the diseased tissue, and subsequently a simple salicylated ointment applied. the operation is repeated from time to time, and as a result the new growth undergoes retrogressive changes, and cicatrization takes place. _punctate scarification._--by means of a simple or multiple-pointed instrument numerous closely-set punctures are made, and repeated from time to time, usually with the same action and result as from linear scarification. _erasion._--the parts are thoroughly scraped with a curette, and a supplementary caustic application made, either with caustic potash or several days' use of the pyrogallic-acid ointment. the result is usually satisfactory. the dental-burr is also useful in breaking up discrete tubercles. _excision._--this is an effective method if the disease consists of a small peaor bean-sized circumscribed patch. of these various operative methods those now most favored are erasion and excision, punctate and linear scarification methods are now rarely employed. #tuberculosis cutis.#[d] (_synonym:_ scrofuloderma.) [footnote d: the most important clinical variety of this class is lupus vulgaris, which is considered above, separately, at some length.] #what do you understand by tuberculosis cutis?# the term is applied to those peculiar suppurative and ulcerative conditions of the skin due to the tubercle bacilli. #how does the common type of tuberculosis cutis begin?# the most common type of tuberculous ulceration or involvement of the skin usually results by extension from an underlying caseating and suppurating lymphatic gland; or it may have its origin as subcutaneous tubercles independently of these structures. it tends to spread, and may involve an area of one or several inches. [illustration: fig. 48. tuberculosis verrucosa cutis (negro).] #what are the clinical appearances and behavior of this type of tuberculous ulceration?# it is usually superficial, has thin, red, undermined edges of a violaceous color, and an irregular base with granulations covered scantily with pus. as a rule, it spreads gradually as a simple ulceration, with but slight, if any, outlying infiltration. subjective symptoms of a painful or troublesome character are rarely present. its course is usually progressive but slow and chronic. other symptoms of tuberculosis are commonly to be found. #are other forms of tuberculosis cutis met with?# a papulo-pustular eruption is sometimes observed, especially on the upper extremities and face; sluggish and chronic in character and leaving small pit-like scars; has been known as the _small pustular scrofuloderma_. [illustration: fig. 49. tuberculosis verrucosa cutis (patient had a coexistent pulmonary tuberculosis).] an ulcerative papillomatous or verrucous tuberculosis of the skin (tuberculosis verrucosa cutis) is also occasionally noted, most commonly seated upon the lower leg or the back of the hand. it may be slight or extensive. its mildest phase is the so-called verruca necrogenica. #describe verruca necrogenica.# verruca necrogenica is a rare, localized, papillary or wart-like formation, occurring usually about the knuckles or other parts of the hand. it begins, as a rule, as a small, papule-like growth, increasing gradually in area, and when well advanced appears as a pea, dime-sized or larger, somewhat inflammatory, elevated, flat, warty mass, with usually a tendency to slight pus-formation between the hypertrophied papillæ; the surface may be horny or it may be crusted. it tends to enlarge slowly and is usually persistent, but it at times undergoes involution. [illustration: fig. 50. tuberculosis cutis (verruca necrogenica). (_after model in guy's museum._)] #state the etiology.# heredity, insufficient and unwholesome food, impure air, and the like are predisposing. the tubercle bacillus is the immediate exciting cause. the disease usually appears in childhood or early adult life, and not infrequently follows in the wake of some severe systemic disease. etiologically it is identical in nature with lupus. #how is the tuberculous ulcer to be differentiated from syphilis?# by the peculiar character of the tuberculous ulceration, the absence of outlying tubercles and infiltration, together with its history, course, and often the presence of other tuberculous symptoms. #state the prognosis.# these various types of tuberculosis cutis are, as a rule, more amenable to treatment than that form known as lupus vulgaris (_q. v._). #what is the treatment of these forms of tuberculosis cutis?# constitutional remedies, such as cod-liver oil, iodide of iron or other ferruginous tonics, together with good food and pure air; phosphorus one-hundredth to one-fiftieth of a grain three times daily is also of benefit in some cases. the local treatment consists in thorough curetting and the subsequent application of a mildly stimulating ointment. the several other plans of external treatment employed in lupus (_q. v._) are also variously practised. in recent years the _x_-ray and finsen light plans have, in a measure, supplanted the previous methods of treatment. they are slow, however, and might be, especially the _x_-ray, more satisfactorily employed as a supplementary measure. #ainhum.# #describe ainhum.# ainhum is a disease of the african race, met with chiefly in brazil, the west indies, and africa, and consists of a slow but gradual linear strangulation of one or more of the toes, especially the smallest, resulting, eventually, in spontaneous amputation. the affected toes themselves undergo fatty degeneration, often with increase in size, and are, when strangulation is well advanced, considerably misshapen. the nature of the disease is obscure. _treatment_ consists, in the early stages, of incision through the constricting band; when the disease is well advanced, amputation is the sole recourse. #mycetoma.# (_synonyms:_ fungous foot of india; madura foot; podelcoma.) #decribe mycetoma.# it is a disease involving usually the foot, and is met with chiefly in india. it is characterized by swelling and the formation of tubercular or nodular lesions which break down and form the external openings of sinuses which lead to the interior of the affected part. these discharge, and are studded with, whitish granules or black, roe-like masses, mixed with a sanious or sero-purulent fluid. the whole part is gradually disintegrated, the process lasting indefinitely. its nature is obscure; it is thought to be due to a fungus. _treatment_ consists in the early stages, when the disease is limited, of thorough curetting and cauterization; later, after the part is more or less involved, amputation, at a point well up beyond the disease, becomes necessary. potassium iodide internally may exert a favorable influence. #perforating ulcer of the foot.# #describe perforating ulcer of the foot.# perforating ulcer of the foot is a rare disease, consisting of an indolent and usually painless sinus leading down to diseased bone. the external opening, which is through the centre of a corn-like formation, is small, and may or may not show the presence of granulations. the affected part is commonly more or less anæsthetic and of subnormal temperature. one or several may be present, either on one or both feet. the most common site is over the articulation of the metatarsal bone with the phalanx of the first or last toe. the disease is dependent upon impairment or degeneration of the central, truncal or peripheral nerves. #what is to be said in regard to the prognosis and treatment?# treatment, which is, as a rule, unsatisfactory, consists in the maintenance of absolute rest, and the use of antiseptic and stimulating applications. amputation is also resorted to, but even this is at times futile, as a new sinus may appear upon the stump. #syphilis cutanea.# (_synonyms:_ syphiloderma; dermatosyphilis; syphilis of the skin.) #in what various types may syphilis manifest itself upon the integument?# syphilis may show itself as a macular, papular (rarely vesicular), pustular, bullous, tubercular and gummatous eruption; or the eruption may be, in a measure, of a mixed type. #in what respects do the early (or secondary) eruptions of syphilis differ from those following several years or more after the contraction of the disease?# the early or secondary eruptions are more or less generalized, with rarely any attempt at special configuration. their appearance is often preceded by symptoms of systemic disturbance, such as fever, loss of appetite, muscular pains and headache; and accompanied by concomitant signs of the disease, such as enlargement of the lymphatic glands, sore throat, mucous patches, falling of the hair and rheumatic pains. #state the distinguishing characters of the late eruptions.# the late eruptions (those following one or more years after the contraction of the disease) are usually of tubercular, gummatous or ulcerative type; are limited in extent, and have a marked tendency to appear in circular, semicircular or crescentic forms or groups. pain in the bones, bone lesions and other symptoms may or may not be present. #what is the color of syphilitic lesions?# usually, a dull brownish-red or ham-red, with at times a yellowish cast. #are there any subjective symptoms in syphilitic eruptions?# as a rule, no; but in exceptional instances of the generalized eruptions, more especially in negroes, there may be slight itching. #describe the macular, or erythematous, eruption of syphilis.# the _macular syphiloderm_ is a general eruption, showing itself usually six or eight weeks after the appearance of the chancre. it consists of small or large, commonly peaor bean-sized, rounded or irregularly-shaped, not infrequently slightly raised, macules. when well established they do not entirely disappear under pressure. at first a pale-pink or dull, violaceous red, they later become yellowish or coppery. the eruption is generally profuse; the face, backs of the hands and feet may escape. it persists several weeks or one or two months; as a rule, it is rapidly responsive to treatment. #how would you distinguish the macular syphiloderm from measles, rötheln and tinea versicolor?# measles is to be differentiated by its catarrhal symptoms, fever, form and situation of the eruption; rötheln, by its small, roundish, confluent pinkish or reddish patches, its precursory pyrexic symptoms, its epidemic nature, and short duration; tinea versicolor by its scaliness, peripheral growth, distribution and history. and, finally, by the absence or presence of other symptoms of syphilis. [illustration: fig. 51. macular syphiloderm.] #what several varieties of the papular eruption of syphilis are met with?# there are two forms of the papular eruption--the small and large; those of the latter type may undergo various modifications. #describe the small-papular eruption of syphilis.# the _small-papular syphiloderm_ (_miliary papular syphiloderm_) usually shows itself in the third or fourth month of the disease, and consists of a more or less generalized eruption of disseminated or grouped, firm, rounded or acuminated pin-head to millet-seed-sized papules, with smooth or slightly scaly summits, and in some lesions showing pointed pustulation. scattered minute pustules and some large papules are usually present. the eruption is profuse, most abundant upon the trunk and limbs; and in the early part of the outbreak is of a brightor dull-red color, later assuming a violaceous or brownish tint. it runs a chronic course, is somewhat rebellious to treatment, and displays a tendency to relapse. [illustration: fig. 52. moist papules. (_after miller._)] #how would you distinguish the small-papular syphiloderm from keratosis pilaris, psoriasis punctata, papular eczema, and lichen ruber?# the distribution and extent of the eruption, the color, the grouping, with usually the presence of pustules and large papules and other concomitant symptoms of syphilis, are points of difference. pustules never occur in the several diseases named, except in eczema. #describe the large-papular eruption of syphilis.# the _large-papular syphiloderm_ (or _lenticular syphiloderm_) is a common form of cutaneous syphilis, appearing usually in the first six or eight months, and consists of a more or less generalized eruption of peato dime-sized or larger, flat, rounded or oval, firmly seated, more or less raised, dull-red papules; with at first a smooth surface, which later usually becomes covered with a film of exfoliating epidermis. the papules, as a rule, develop slowly, remain stationary several weeks or a few months, and then pass away by absorption, leaving slight pigmentation, which gradually fades; or they may undergo certain modifications. in most cases it responds rapidly to treatment. [illustration: small-papular syphiloderm.] [illustration: fig. 53. palmar syphiloderm.] #what modifications do the papules of the large-papular syphiloderm sometimes undergo?# they may change into the moist papule and squamous papule. #describe the moist papule of syphilis.# the change into the moist papule (also called _mucous patch, flat condyloma_) is not uncommon where opposing surfaces and natural folds of skin are subjected to more or less contact, as about the anus, the scroto-femoral regions, umbilicus, axillæ and beneath the mammæ. the dry, flat papules gradually become moist and covered with a grayish, sticky, mucoid secretion; several may coalesce and form large, flat patches. they may so remain, or they may become hypertrophic, warty or papillomatous, with more or less crust formation (_vegetating syphiloderm_). [illustration: fig. 54. annular syphiloderm. (_after i.e. atkinson._)] #describe the squamous papule of syphilis.# this tendency of the large-papular eruption to become scaly, when exhibited, is more or less common to all papules, and constitutes the _squamous_ or _papulo-squamous syphiloderm_ (improperly called _psoriasis syphilitica_). the papules become somewhat flattened and are covered with dry, grayish or dirty-gray, somewhat adherent scales. the scaling, as compared to that of psoriasis, is, as a rule, relatively slight. the eruption may be general, as usually the case in the earlier months of the disease, or it may appear as a relapse or a later manifestation, and be limited in extent. as a limited eruption it is most frequently seen on the palms and soles--the _palmar and plantar syphiloderm_. occurring on these parts it is often rebellious to treatment. [illustration: maculo-papular syphiloderm.] #how are you to distinguish the papulo-squamous syphiloderm from psoriasis?# in psoriasis the eruption is more inflammatory, and usually bright red; the scales whitish or pearl-colored and, as a rule, abundant. it is generally seen in greater profusion upon certain parts, as, for instance, the extensor surfaces, especially of the elbows and knees. it is not infrequently itchy, and, moreover, presents a different history. in the syphilitic eruption some of the papules almost invariably remain perfectly free from any tendency to scale formation; there is distinct deposit or infiltration, and the lesions are of a dark, sluggish red or ham tint; and, moreover, concomitant symptoms of syphilis are usually present. #describe the annular eruption of syphilis.# the _annular syphiloderm_ (_circinate syphiloderm_) is observed usually in association with the large-papular eruption, and consists of several or more variously sized, ring-like lesions, with a distinctly elevated solid ridge or wall peripherally and a more or less flattened centre. it is commonly seen about the mouth, forehead and neck. the lesion appears to have its origin from an ordinary, usually scaleless or slightly scaly, large papule, the central portion of which has been incompletely formed or has become sunken and flattened. the manifestation is rare, and is seen most frequently in the negro. #what several varieties of the pustular syphiloderm are met with?# the small acuminated-pustular syphiloderm, the large acuminated-pustular syphiloderm, the small flat-pustular syphiloderm, and the large flat-pustular syphiloderm. #describe the small acuminated-pustular eruption of syphilis.# the _small acuminated-pustular syphiloderm_ (_miliary pustular syphiloderm_) is an early or late secondary eruption, commonly encountered in the first six or eight months of the disease. it consists of a more or less generalized, disseminated or grouped, millet-seed-sized, acuminated pustules, usually seated upon dull-red, papular elevations. the eruption is, as a rule, profuse, and usually involves the hair-follicles. the pustules dry to crusts, which fall off and are often followed by a slight, fringe-like exfoliation around the base, constituting a grayish ring or collar. minute pin-point atrophic depressions or stains are left, which gradually become less distinct. scattered large pustules, and sometimes papules, are not infrequently present. #describe the large acuminated-pustular eruption of syphilis.# the _large acuminated-pustular syphiloderm_ (_acne-form syphiloderm_, _variola-form syphiloderm_) is a more or less generalized eruption, occurring usually in the first six or eight months of the disease. it consists of small or large pea-sized, disseminated or grouped, acuminated or rounded pustules, resembling the lesions of acne and variola. they develop slowly or rapidly, and at first may appear more or less papular. they dry to somewhat thick crusts, and are seated upon superficially ulcerated bases. it pursues, as a rule, a comparatively rapid and benign course. in relapses the eruption is usually more or less localized. #how would you distinguish the large acuminated-pustular syphiloderm from acne and variola?# in acne the usual limitation of the lesions to the face or face and shoulders, the origin, more rapid formation and evolution of the individual lesions, and the chronic character of the disease, are usually distinctive points. in variola, the intensity of the general symptoms, the shot-like beginning of the lesions, their course, the umbilication, and the definite duration, are to be considered. the presence or absence of other symptoms of syphilis has, in obscure cases, an important diagnostic bearing. #describe the small flat-pustular eruption of syphilis.# the _small flat-pustular syphiloderm_ (_impetigo-form syphiloderm_) consists of a more or less generalized, pea-sized, flat or raised, discrete, irregularly-grouped, or in places confluent, pustules, appearing usually in the first year of the disease. the pustules dry rapidly to yellow, greenish-yellow, or brownish, more or less adherent, thick, uneven, somewhat granular crusts, beneath which there may be superficial or deep ulceration; where the lesions are confluent a continuous sheet of crusting forms. the eruption is often scanty. it is most frequently observed about the nose, mouth, hairy parts of the face and scalp, and about the genitalia, frequently in association with papules on other parts. #are you likely to mistake the small flat-pustular syphiloderm for any other eruption?# scarcely; but when upon the scalp, it may bear rough resemblance to pustular eczema, but the erosion or ulceration will serve to differentiate. moreover, concomitant symptoms of syphilis are to be looked for. #describe the large flat-pustular eruption of syphilis.# the _large flat-pustular syphiloderm_ (_ecthyma-form syphiloderm_) consists of a more or less generalized, scattered eruption, of large peaor dime-sized, flat pustules. they dry rapidly to crusts. the bases of the lesions are a deep-red or copper color. two types of the eruption are met with. in one type--the superficial variety--the crust is flat, rounded or ovalish, of a yellowish-brown or dark-brown color, and seated upon a superficial erosion or ulcer. the lesions are usually numerous, and most abundant on the back, shoulders and extremities. it appears, as a rule, within the first year, and generally runs a benign course. [illustration: fig. 55. rupia. (_after tilbury fox._)] in the other type--the deep variety--the crust is greenish or blackish, is raised and more bulky, often conical and stratified, like an oyster shell--_rupia_; beneath the crusts may be seen rounded or irregular-shaped ulcers, having a greenish-yellow, puriform secretion. it is usually a late and malignant manifestation. #how would you differentiate the large flat-pustular syphiloderm from ecthyma?# the syphilitic lesions are more numerous, are scattered, are attended with superficial or deep ulceration, and followed by more or less scar-formation. moreover, the history, and presence or absence of other symptoms of syphilis have an important diagnostic value. [illustration: fig. 56. ulcerating tubercular syphiloderm.] #describe the bullous eruption of syphilis.# the _bullous syphiloderm_, (of acquired syphilis) is a rare and usually late eruption, appearing in the form of discrete, disseminated, rounded or ovalish, peato walnut-sized, partially or fully distended, blebs. the serous contents soon become cloudy and puriform. in some cases the lesions are distinctly pustular from the beginning. the crust, which soon forms, is of a yellowish-brown or dark green color, and may be thick and stratified (_rupia_), as in the deep variety of the large flat-pustular syphiloderm. the erosions or ulcers beneath the crusts secrete a greenish-yellow fluid. it is a malignant type of eruption, and is usually seen in broken-down subjects. it is not an uncommon manifestation of hereditary syphilis (_q. v._) in the newborn. [illustration: fig. 57. tubercular syphiloderm.] #how is the bullous syphiloderm to be differentiated from other pemphigoid eruptions?# by the gravity of the disease, the accompanying ulceration, the course and history; and by other evidences, past or present, of syphilis. #describe the tubercular eruption of syphilis.# the _tubercular syphiloderm_ (_syphiloderma tuberculosum_) may exceptionally occur within the first year as a more or less generalized eruption. as a rule, however, it is a late manifestation, at times appearing many years after the initial lesion; is limited in extent, and shows a decided tendency to occur in groups, often forming segments of circles and circular areas, clearing in the centre and spreading peripherally. it consists (as a late, limited manifestation) of several or more firm, circumscribed, deeply-seated, smooth, glistening or slightly scaly elevations; rounded or acuminated in shape, of a yellowish-red, brownish-red or coppery color and usually of the size of small or large peas. several groups may coalesce, and a serpiginous tract result (_serpiginous tubercular syphiloderm_). the lesions develop slowly, and are sluggish in their course, remaining, at times, for weeks or months, with but little change. as a rule, however, they terminate sooner or later, either by absorption, leaving a more or less permanent pigment stain with or without slight atrophy (_non-ulcerating tubercular syphiloderm_), or by ulceration (_ulcerating tubercular syphiloderm_). [illustration: fig. 58. ulcerating tubercular syphiloderm.] #describe the ulcerating tubercular syphiloderm.# the ulceration may be superficial or deep in character, and involve several or all of the lesions forming the group. the patch may consist, therefore, of small, discrete, punched-out ulcers, or of one or more continuous ulcers, segmented, crescentic or serpiginous in shape. they are covered with a gummy, grayish-yellow deposit or they may be crusted. as the ulcerative changes take place, new lesions, especially about the periphery of the group or patch, may appear from time to time. [illustration: tubercular syphiloderm.] [illustration: large-pustular syphiloderm.] in some instances, more especially about the scalp, the surface of the ulcerations becomes papillary or wart-like, with an offensive, yellowish, puriform secretion (_syphilis cutanea papillomatosa_). #from what diseases is the tubercular syphiloderm to be differentiated?# from tubercular leprosy, epithelioma and lupus vulgaris, especially the last-named. #what are the chief diagnostic characters of the tubercular syphiloderm?# the tendency to form segments, crescents and circles, the color, the pigmentation and ulceration, the history, and not infrequently marks or scars of former eruptions. [illustration: fig. 59. tubercular syphiloderm.] #describe the gummatous eruption of syphilis.# the _gummatous syphiloderm_ (_syphiloderma gummatosum_, _gumma_, _syphiloma_) is usually a late manifestation, showing itself as one, several or more painless or slightly painful, rounded or flat, more or less circumscribed tumors; they are slightly raised, moderately firm, and have their seat in the subcutaneous tissue. they tend to break down and ulcerate. the lesion begins usually as a pea-sized deposit or infiltration, and grows slowly or rapidly; when fully developed it may be the size of a walnut, or even larger. the overlying skin becomes gradually reddish. at first firm, it is later soft and doughy. it may, even when well advanced, disappear by absorption, but usually tends to break down, terminating in a small or large, deep, punched-out ulcer. [illustration: fig. 60. tubercular syphiloderm.] #does the gummatous syphiloderm invariably appear as a rounded well-defined tumor?# no. exceptionally, instead of a well-defined tumor, it may appear as a more or less diffused patch of infiltration, leading eventually to extensive superficial or deep ulceration. #from what formations is the gummatous syphiloderm to be differentiated?# from furuncle, abscess, and sebaceous, fatty and fibroid tumors. attention to the origin, course, and behavior of the lesion, together with a history, must all be considered in doubtful cases. [illustration: fig. 61. large pustular syphiloderm.] #what is to be said in regard to the character and time of appearance of the cutaneous manifestations of hereditary syphilis?# in a great measure the cutaneous manifestations of hereditary syphilis are essentially the same as observed in acquired syphilis. they are usually noted to occur within the first three months of extra-uterine life. the macular, papular, and bullous eruptions are most common. #describe these several cutaneous manifestations of hereditary syphilis.# the _macular_ (erythematous) eruption begins as large or small, brightor dark-red macules, later presenting a ham or café-au-lait appearance. at first they disappear upon pressure. the lesions are more or less numerous, usually become confluent, especially about the folds of the neck, about the genitalia and buttocks; in these regions resembling somewhat erythema intertrigo. the _papular_ eruption is observed in conjunction with the erythematous manifestation, or it occurs alone. the lesions are but slightly elevated, and seem to partake of the nature of both macules and papules. they are usually discrete, and rarely abundant; they may become decked with a film-like scale, and at the various points of junction of skin and mucous membrane, and in the folds, they become abraded and macerated, developing into _moist papules_. the _bullous_ eruption consists of variously-sized, more or less purulent blebs, and is usually met with at or immediately following birth. it is most abundant about the hands and feet. macules and papules are often interspersed. there may be superficial or deep ulceration underlying the bullæ. #what other symptoms in addition to the cutaneous manifestations are noted in hereditary syphilis in the newborn?# mucous patches, and sometimes ulcers, in the mouth and throat; hoarseness, as shown by the peculiar cry, and indicating involvement of the larynx; snuffles, a sallow and dirty appearance of the skin, loss of flesh and often a shriveled or senile look. #what is the pathology of cutaneous syphilis?# the syphilitic deposit consists of round-cell infiltration. the mucous layer, the corium, and in the deep lesions the subcutaneous connective tissues also, are involved in the process. the infiltration disappears by absorption or ulceration. the factor now believed to be responsible for the disease and the pathological changes is the spirochæta pallida, discovered by schaudinn and hoffmann, and usually found in numbers in the tissues. #give the prognosis of cutaneous syphilis.# in _acquired syphilis_, favorable; sooner or later, unless the whole system is so profoundly affected by the syphilitic poison that a fatal ending ensues, the cutaneous manifestations disappear, either spontaneously or as the result of treatment. the earlier eruptions will often pass away without medication, but treatment is of material aid in moderating their severity and hastening their disappearance, and is to be looked upon as essential; in the late syphilodermata treatment is indispensable. in the large pustular, the tubercular and gummatous lesions, considerable destruction of tissue may take place, and in consequence scarring result. ill-health from any cause predisposes to a relapse, and also adds to the gravity of the case. in _hereditary infantile syphilis_, the prognosis is always uncertain: the more distant from the time of birth the manifestations appear the more favorable usually is the outcome. #how is cutaneous syphilis to be treated?# always with constitutional remedies; and in the graver eruptions, and especially in those more or less limited, with local applications also. #what constitutional and local remedies are commonly employed in cutaneous syphilis?# _constitutional remedies._--mercury and potassium iodide; tonics and nutrients are necessary in some cases. _local remedies._--mercurial ointments, lotions and baths, and iodol in ointment or in (and also calomel) powder form. #give the constitutional treatment of the earlier, or secondary, eruptions of syphilis.# in secondary or early eruptions mercury alone in almost every case; with tonics, if called for. if mercury is contraindicated (extremely rare), potassium iodide may be substituted. #how is mercury usually administered in the eruptions of secondary syphilis?# by the mouth, chiefly as the protiodide, calomel and blue mass, in dosage just short of mild physiological action; by _inunction_, in the form of blue ointment; by _hypodermic injection_, usually as corrosive sublimate solution. the method by _fumigation_, with calomel or bisulphuret, is now rarely employed. the method by the mouth is the common one, and it is only in rare instances that any other method is necessary or advisable. #what local applications are usually advised in the eruptions of secondary syphilis?# if the eruption is extensive, and more especially in the pustular types, baths of corrosive sublimate ([dram ii-dram-iv] to cong. xxx) may be used; and ointment of ammoniated mercury, twenty to sixty grains to the ounce, blue ointment, and the ten per cent. oleate of mercury alone or with an equal quantity of any ointment base. the same applications or a dusting powder of calomel may also be used on moist papules. #how long is mercury to be actively continued in cases of early (secondary) syphilis?# until one or two months after all manifestations (cutaneous or other) have disappeared, and then, as a general rule, continued, as a small daily dose (about one-quarter to one-third of that prescribed during the active treatment) for a period of two or three months; then another cycle of the active dosage for a period of four to six weeks; then a resumption of the smaller daily dose for another two or three months; and so on, for a period of at least two years. (almost all authorities are agreed as to the importance of prolonged treatment, but differ somewhat on the question of intermittent or uninterrupted administration.) #give the constitutional treatment of the late, or localized, syphilodermata.# mercury always, usually in small or moderate dosage, as the biniodide or corrosive chloride, and potassium iodide; the latter in dose varying from two grains to two drachms or more, t.d., depending upon its action and the urgency of the case. #how long is constitutional treatment to be continued in cases of the late syphilodermata?# actively for several weeks after the disappearance of all symptoms, and then (especially the mercury) continued in smaller dosage (about one-third) for several months longer. #what applications are usually advised in the late, or localized, syphilodermata?# ointment of ammoniated mercury, twenty to sixty grains to the ounce; oleate of mercury, five to ten per cent. strength; mercurial plaster, full strength or weakened with lard or petrolatum; a two to twenty per cent. ointment of iodol; resorcin, twenty to sixty grains to the ounce of ointment base; and lotions of corrosive sublimate, one-half to three grains to the ounce. the following is valuable in offensive and obstinate ulcerations:- [rx] hydrarg. chlorid. corros., ........... gr. iv-gr. viij ac. carbolici, ....................... gr. x-xx alcoholis, ........................... f[dram]iv glycerinæ, ........................... f[dram]j aquæ, ............ q.s. ad ........... [oz]iv. m. ointments are to be rubbed in or applied as a plaster; lotions, employed chiefly in ulcers and ulcerations, are to be thoroughly dabbed on, and usually supplemented by the application of an ointment. iodol may also be applied to ulcers as a dusting-powder, usually mixed with one to several parts of zinc oxide or boric acid. #give the treatment of hereditary infantile syphilis.# it is essentially the same (but much smaller dosage) as employed in acquired syphilis. attention to proper feeding and hygiene is of first importance. mercury may be given by the mouth, as mercury with chalk (gr. ss-gr. ij, t.d.); as calomel (gr. 1/20-gr. 1/6, t.d.); and as a solution of corrosive sublimate (gr. ss-[oz]vj, [dram]j, t.d.). if mercury is not well borne by the stomach, it may be administered by inunction; for this purpose, blue ointment is mixed with one or two parts of lard and spread (about a drachm) upon an abdominal bandage and applied, being renewed daily. treatment by means of baths (gr. x-xxx to the bath) of corrosive sublimate is, at times, a serviceable method. potassium iodide, if exceptionally deemed preferable, may be given in the dose of a fractional part of a grain to two or three grains three times daily. #what local measures are to be advised in cutaneous syphilis of the newborn?# if demanded, applications similar to those employed in eruptions of acquired syphilis, but not more than one-third to one-half the strength. #lepra.# (_synonyms:_ leprosy; elephantiasis græcorum.) #what do you understand by leprosy?# lepra, or leprosy, is an endemic, chronic, malignant constitutional disease, characterized by alterations in the cutaneous, nerve, and bone structures; varying in its morbid manifestations according to whether the skin, nerves or other tissues are predominantly involved. #what is the nature of the premonitory symptoms of leprosy?# in some instances the active manifestations appear without premonition, but in the majority of cases symptoms, slight or severe in character, pointing toward profound constitutional disturbance, such as mental depression, malaise, chills, febrile attacks, digestive derangements and bone pains, are noticed for weeks, months, or several years preceding the outbreak. #what several varieties of leprosy are observed?# two definite forms are usually described--the tubercular and the anæsthetic. a sharp division-line cannot, however, always be drawn; not infrequently the manifestations are of a mixed type, or one form may pass into or gradually present symptoms of the other. [illustration: fig. 62. tubercular leprosy. (_after stoddard._)] #describe the symptoms of tubercular leprosy.# the formation of tubercles and tubercular masses of infiltration, usually of a yellowish-brown color, with subsequent ulceration, constitute the important cutaneous symptoms. along with, or preceding these characteristic lesions, blebs and more or less infiltrated, hyperæsthetic or anæsthetic, pinkish, reddish or pale-yellowish macules make their appearance from time to time; subsequently fading away or remaining permanently (_lepra maculosa_). when well advanced, the tubercular or nodular masses give rise to great deformity; the face, a favorite locality, becomes more or less leonine in appearance (_leontiasis_). the tubercles persist almost indefinitely without material change, or undergo absorption or ulceration; this last takes place most commonly about the fingers and toes. the mucous membrane of the mouth, pharynx and other parts may also become involved. [illustration: fig. 63. anæsthetic leprosy.] #describe the symptoms of anæsthetic leprosy.# following or along with precursory symptoms denoting general systemic disturbance, or independently of any prodromal indications, a hyperæsthetic condition, in localized areas or more or less general, is observed. lancinating pains along the nerves and an irregular pemphigoid eruption are also commonly noted. there soon follows the special eruption, coming out from time to time, and consisting of several or more, usually non-elevated, well-defined, pale-yellowish patches, one or two inches in diameter. as a rule, they are at first neither hyperæsthetic nor anæsthetic, but may be the seat of slight burning or itching. they spread peripherally, and tend to clear in the centre. the patches eventually become markedly anæsthetic, and the overlying skin, and the skin on other parts as well, becomes atrophic and of a brownish or yellowish color. the subcutaneous tissues, muscle, hair and nails undergo atrophic or degenerative changes, and these changes are especially noted about the hands and feet. these parts become crooked, the bone tissues are involved, the phalanges dropping off or disappearing by disintegration or absorption (_lepra mutilans_). sooner or later various paralytic symptoms, showing more active involvement of the nerve trunks, present themselves. #state the cause of leprosy.# present knowledge points to a peculiar bacillus as the active factor, while climate, soil, heredity, food and habits exert a predisposing influence. #is leprosy contagious?# the consensus of opinion points to the acceptance of the possible contagiousness of leprosy; probably by inoculation, but only under certain unknown favoring conditions. #what are the pathological changes?# the lesions consist essentially of a new growth, made up of numerous small, more or less aggregated round cells, beginning in the walls of the bloodvessels. in this way the tubercular masses and various other lesions are formed. as yet, positive involvement ot the central nervous system has not been shown, but some of the nerve trunks are found to be inflamed and swollen, with a tendency toward hardening. #what several diseases are to be eliminated in the diagnosis of leprosy?# syphilis, morph[oe]a, vitiligo, lupus, and syringomyelia. when well advanced, the aggregate symptoms of leprosy form a picture which can scarcely be confused with that of any other disease. in doubtful cases microscopical examinations of the involved tissues, for the bacilli, should be made. #state the prognosis of leprosy.# unfavorable; a fatal termination is the rule, but may not be reached for a number of years. the tubercular form is the most grave, the mixed variety next, and the anæsthetic the least. patients are not infrequently carried off by intercurrent disease. proper management will often delay the fatal ending, and exceptionally, in the anæsthetic variety, stay the progress of the disease. #what is the treatment of leprosy?# hygienic measures are important. chaulmoogra oil and gurjun oil internally and externally are in some instances of service. strychnia alone, or with either of these oils, is ofttimes beneficial. ichthyol internally, and external applications of the same drug, and of resorcin, chrysarobin, and pyrogallic acid, have been extolled. change of climate, especially to a region where the disease does not prevail, is often of great advantage. #pellagra.# (_synonym:_ lombardian leprosy.) #describe pellagra.# pellagra is a slow but usually progressive disease occurring chiefly in italy, due, it is thought, to the continued ingestion of decomposed or fermented maize. it is characterized by cutaneous symptoms, at first upon exposed parts, of an erythematous, desquamative, vesicular and bullous character, and by general constitutional disturbance of a markedly neurotic type. a fatal ending, if the disease is at all severe or advanced, is to be expected. treatment is based upon general principles. #epithelioma.# (_synonyms:_ skin cancer; epithelial cancer; carcinoma epitheliale.) #what several varieties of epithelioma are met with?# three--the superficial, the deep-seated, and the papillomatous. #describe the clinical appearances and course of the superficial variety of epithelioma.# the superficial, or flat variety (_rodent ulcer_), begins, usually on the face, as a minute, firm, reddish or yellowish tubercle, as an aggregation of such, as a warty excrescence, or as a localized degenerative seborrh[oe]ic patch. the latter lesion (known also as keratosis senilis, old-age atrophic patches), consisting of a yellowish or yellowish-brown greasy or hardened scurfy spot or patch is quite frequently the starting-point of epithelial growths. sooner or later, commonly after months or several years, the surface becomes slightly excoriated, and an insignificant, yellowish or brownish crust is formed. the excoriation gradually develops into superficial ulceration, and the diseased area becomes slowly larger and larger. new lesions may continue, from time to time, to appear about the edges and go through the same changes. [illustration: fig. 64. epithelioma. (_after d. lewis._)] the ulcer has usually an uneven surface, secretes a thin, scanty, viscid fluid, which dries to a firm, adherent crust. it is usually defined against the healthy skin by a slightly elevated, hard, roll-like, waxy-looking border. in rare instances there is a disposition, at points, to spontaneous involution and scar formation; as a rule, however, the ulcerative action slowly progresses. the general health is unimpaired, the neighboring lymphatic glands are not involved, and the local condition, beyond the disfigurement, gives rise to little trouble, unless, as occasionally happens, it passes into the more malignant, deep-seated variety. #describe the clinical appearances and course of the deep-seated variety of epithelioma.# the deep-seated variety starts from the superficial form, or it begins as a tubercle or nodule in the skin. when typically developed, a reddish, shining tubercle or nodule, or area of infiltration, forms in the skin or subcutaneous tissue. in the course of weeks or months superficial or deep-seated ulceration takes place; the ulcer having hardened, and, as a rule, everted edges. the surface is reddish and granular, and secretes an ichorous discharge. the infiltration spreads, the ulcer enlarges both peripherally and in depth--muscle, cartilage and bone often becoming invaded. the neighboring lymphatic gland may become implicated, pains of a burning or neuralgic type are experienced, and from septicæmia, marasmus, or involvement of vital parts, death eventually ensues. #describe the clinical appearances and course of the papillomatous variety of epithelioma.# the papillomatous type usually arises from the superficial or deep-seated variety, or it may begin as a papillary or warty growth. when fully developed, it presents an ulcerated, fissured and papillomatous surface, with an ichorous discharge which dries to crusts. it is slowly progressive, and sooner or later may develop a malignant tendency. #upon what parts is epithelioma commonly observed?# about the face, especially the nose, eyelids and lips; and also about the genitalia. it may involve any part. #at what age is epithelioma usually noted?# it is essentially a disease of middle and late life, although it is exceptionally met with in the young. #what is the cause of epithelioma?# the etiology is obscure. it is not, as a rule, inherited. any locally irritated tissue may be the starting point of the disease. #state the pathology.# the process consists in the proliferation of epithelial cells from the mucous layer; the cell-growth takes place downward, in the form of finger-like prolongations or columns, or it may spread out laterally, so as to form rounded masses, the centres of which usually undergo horny transformation, resulting in the formation of onion-like bodies, the so-called cell-nests or globes. the rapid cell-growth requires increased nutriment, and hence the bloodvessels become enlarged; moreover, the pressure of the cell-masses gives rise to irritation and inflammation, with corresponding serous and round-cell infiltration. #how would you distinguish epithelioma from syphilitic ulceration, wart, and lupus vulgaris?# from syphilis it is to be differentiated by the history, duration, character of the base and edges, its comparative slow progress, its usually slight, viscid discharge, often streaked with blood, and, if necessary, by the therapeutic test. wart or warty growths are to be differentiated by attention to their history and course. long-continued observation may be necessary before a positive opinion is warrantable. the appearance of any tendency to crusting, to break down or ulcerate is significant of epitheliomatous degeneration. in lupus vulgaris the deposits are peculiar and multiple, the ulcerations are of different character, the tendency to scar-formation constant; and, with few exceptions, it has, moreover, its beginning in childhood or early adult life. #what factors are to be considered in giving a prognosis in epithelioma?# the variety, extent, and rapidity of the process. the superficial form may exist for years, and give rise to no alarm; whereas the deeper-seated varieties are always to be viewed as serious, and are, indeed, often fatal. involving the genitalia, its course is often strikingly rapid. relapses, after removal, are not uncommon. #what is the special object in view in the treatment of epithelioma?# thorough destruction or removal of the epitheliomatous tissue. #how is the destruction or removal of the epitheliomatous tissue effected?# by the use of such caustics as caustic potash, chloride-of-zinc paste, pyrogallic acid, arsenic, and the galvano-cautery; and by operative measures, such as excision and erasion with the dermal curette, and by the _x_-ray. (see treatment of lupus vulgaris.) in small lesions the use of an arsenical paste is a most admirable method of treatment, although somewhat painful. the paste is made of one part powdered acacia and one to two parts arsenious acid; at the time of application sufficient water is added to make a paste. this is applied thickly, and a piece of lint superimposed. a good deal of pain and inflammatory swelling ensue; at the end of twenty-four hours the part is poulticed till the slough comes away; the ulcer is then treated as a simple ulcer, under which healing takes place. occasionally a second application is found necessary. upon the whole, the best method in the average case is to curette thoroughly, and supplement with momentary cauterization, with caustic potash, or with several days' use of the pyrogallic acid ointment. during the healing process, short exposures to the röntgen ray--about every three to five days--is good practice. the degenerative changes in the beginning of scurfy, seborrh[oe]ic spots or patches seen in old people can frequently be lessened or wholly stopped by the daily application of an ointment containing 5 to 10 per cent. of sulphur and 2 to 5 per cent. of salicylic acid. #what can be said of the value of the x-ray in epithelioma?# the _x_-ray method is now much in vogue, and proves curative in many superficial cases, and of benefit in some of the deeper-seated varieties. in most cases it must be pushed to the point of producing a mild _x_-ray erythema; and in some instances benefit or cure only occurs after more active exposure, sufficient to cause an _x_-ray burn of the second degree. the method is not attended with much risk if properly used. the healthy parts should be protected by lead-foil. exposure should be two to five times weekly, at a distance of three to eight inches, and from five to twenty minutes, employing a tube of medium vacuum. unfortunately the method is usually slow. the radium treatment is essentially similar to that by the _x_-ray. the much better plan, as already intimated, is to employ one of the several operative or caustic methods, and supplementing, while healing, with the _x_-ray. #paget's disease of the nipple.# (_synonyms:_ malignant papillary dermatitis; paget's disease.) #what do you understand by paget's disease of the nipple?# paget's disease is a rare, inflammatory-looking, malignant disease of the nipple and areola in women, usually of advancing years, eventually terminating in cancerous involvement of the entire gland. #describe the symptoms of paget's disease.# the first symptoms, which usually last for months or years, are apparently eczematous, accompanied with more or less burning, itching and tingling. gradually, the diseased area, which is sharply-defined, and feels like a thin layer of indurated tissue, presents a florid, intensely red, very finely-granular, raw surface, attended with a more or less copious viscid exudation. sooner or later retraction and destruction of the nipple, followed by gradual scirrhous involvement of the whole breast, takes place. #what is the pathology of paget's disease?# although it was thought at one time to be a cancerous disease resulting from a continued eczematous inflammation of the parts, there is now but little doubt that it is of malignant nature from the earliest stages. the psorosperm-like bodies found, to the presence of which the disease has by some authorities been attributed (psorospermosis), are now known to be merely changed and degenerated epithelia. the morbid changes consist of an inflammation of the papillary region of the derma, leading to [oe]dema and vacuolation of the constituent cells of the epidermis, followed by their complete destruction in places and their abnormal proliferation in others (fordyce). #state the diagnostic features of paget's disease.# the age of the patient; the sharp limitation; the well-defined, indurated film of infiltration; the peculiar, red, raw, granulating appearance; and, later, the retraction of the nipple; and, finally, the involvement of the deeper parts. #what is the prognosis?# if the disease is recognized early, and properly treated, a cure may be anticipated; later the outlook is that of scirrhus of the breast. #what is the treatment of paget's disease?# thorough cauterization by means of caustic potash or the galvano-cautery; or, its extirpation by means of the curette or excision. after extirpation or cauterization, supplementary treatment by the _x_-ray is advisable as an additional measure of precaution against relapse. until the diagnosis is thoroughly established, soothing applications, such as are employed in acute eczema, are to be advised. #sarcoma.# (_synonyms:_ sarcoma cutis; sarcoma of the skin.) #describe the several varieties of sarcoma.# sarcoma of the skin is a more or less malignant new growth, of rapid or slow progress, characterized by the appearance of single or multiple, variously-shaped, discrete, non-pigmented or pigmented tubercles or tumors, of size varying from that of a shot to a hazelnut or larger. as a rule the growths are smooth, firm and elastic, somewhat painful upon pressure, and exhibit a tendency to ulcerate. the overlying skin is at first normal and somewhat movable, but as the growths approach the surface it becomes reddened and adherent; or, if the disease is of the pigmented variety, it acquires a bluish-black color. it is now generally believed that the most of the pigmented cases formerly thought to be of sarcomatous nature are really carcinomatous in character. the multiple pigmented sarcoma (_melano-sarcoma_) appears first, usually on the soles and dorsal surfaces of the feet, and later on the hands. there is more or less diffuse thickening of the integument. the lesions themselves manifest a disposition to bleed. #state the prognosis and treatment of sarcoma.# the disease is always more or less malignant and, as a rule, sooner or later a fatal termination takes place. it is usually slow in its course. excision or extirpation, _x_-ray exposures, and the administration of arsenic in increasing dosage (preferably by hypodermic injection) now are generally considered the most promising in this usually hopeless malady. #granuloma fungoides.# #describe granuloma fungoides.# a rare form of disease, heretofore looked upon as sarcomatous, but now generally recognized as granuloma, and formerly described under the names _mycosis fungoides_, _inflammatory fungoid neoplasm_, and several others. it is characterized usually by symptoms of an eczematous, urticarial, and erysipelatous nature, and by the sudden or gradual appearance of pinkish or reddish, tubercular, nodular, lobulated, or furrowed tumors or flat infiltrations, which may disappear by involution or may be followed by ulceration; several or a larger number of the growths present a mushroom, papillomatous, or fungoid appearance, sometimes roughly resembling the cut part of a tomato. in most cases the tumor stage of the malady is not reached for two or more years; in exceptional instances, however, they appear in the first few months. the lesions, especially in their early stages, are, as a rule, accompanied with more or less burning and itching. #state the prognosis and treatment of granuloma fungoides.# the malady may last for several years or much longer, a fatal termination, with rare exceptions, sooner or later taking place. after the tumor stage is well established, the patient usually succumbs in from several months to one or two years. [illustration: fig. 65. granuloma fungoides.] treatment consists of tonics, if indicated, and the administration of arsenic, preferably hypodermically, and röntgen-ray exposures, along with the application of mild antiseptics, and operative interference when necessary or advisable. #class vii.--neuroses.# #hyperæsthesia.# #what is hyperæsthesia?# by hyperæsthesia is meant increased cutaneous sensibility. it is usually more or less localized, and is met with as a symptom in functional and organic nervous diseases. #dermatalgia.# (_synonyms:_ neuralgia of the skin; rheumatism of the skin; dermalgia.) #what do you understand by dermatalgia?# by dermatalgia is meant a tender or painful condition of the skin unattended by structural change. it is commonly limited to a small area, and is usually symptomatic of functional or organic nervous disease. as an idiopathic affection it is looked upon as of a rheumatic origin. treatment depends upon the cause. #anæsthesia.# #what is anæsthesia?# anæsthesia is a diminution, comparative or complete, of cutaneous sensibility. it is usually localized, and is met with in the course of certain nervous affections. it is also encountered in leprosy, morph[oe]a and like diseases. #pruritus.# #what do you understand by pruritus?# pruritus is a functional disease of the skin, the sole symptom of which is itching, there being no structural change. #describe the symptoms of pruritus.# the sole and essential symptom is itchiness, usually more or less paroxysmal, and worse at night. there are no primary structural lesions, but in severe and persistent cases the parts become so irritated by continued scratching that secondary lesions, such as papules and slight thickening and infiltration, may result. it is much more common in advanced life--_pruritus senilis_. in such cases, as well as in those cases in younger and middle-aged individuals in which the itchiness develops at the approach of cold weather and disappears upon the coming of the warm season (_pruritus hiemalis_), the pruritus is usually more or less generalized, although not infrequently in the latter the legs are specially involved. in some individuals an attack of pruritus, of variable intensity, lasting from five to thirty minutes, comes on immediately after a bath (_bath-pruritus_). it is usually confined to the legs from the hips down. #is pruritus always more or less generalized?# no; not infrequently the itching is limited to the genital region (_pruritus scroti_, _pruritus vulvæ_) or to the anus (_pruritus ani_). #to what may pruritus often be ascribed?# to digestive and intestinal derangements, hepatic disorders, the uric acid diathesis, gestation, diabetes mellitus, and a depraved state of the nervous system. pruritus vulvæ is at times due to irritating discharges, and pruritus ani occasionally to hemorrhoids and seat-worms. #is there any difficulty in the diagnosis of pruritus?# no. the subjective symptom of itching without the presence of structural lesions is diagnostic. in those severe and persistent cases in which excoriations and papules have resulted from the scratching, the history of the case, together with its course, must be considered. care should be taken not to confound it with pediculosis. in this latter the excoriations usually have a somewhat peculiar distribution, being most abundant on those parts of the body with which the clothing lies closely in contact. (see pediculosis corporis.) in pruritus of the genitocrural region the possibility of pediculi being the cause must be kept in mind; an examination of the parts for the parasite or for ova (attached to the hairs) would prevent error. (see pediculosis pubis.) #what prognosis would you give in pruritus?# in the majority of cases the condition responds to proper treatment, but in others it proves rebellious. the prognosis depends, in fact, upon the removability of the cause. temporary relief may always be given by external applications. #how would you treat pruritus?# with systemic remedies directed toward a removal or modification of the etiological factors, and, for the temporary relief of the itching, suitable antipruritic applications. in obscure cases, quinia, salophen, lithia salts, calcium chloride, belladonna, nux vomica, arsenic, pilocarpine, and general galvanization may be variously tried. alkalies prove useful in many cases. exceptionally, the relief furnished by external treatment is more or less permanent. #name the important antipruritic applications.# alkaline baths; lotions of carbolic acid ([dram]j-[dram]iij to oj), of resorcin ([dram]j-[dram]iv to oj), of liquor carbonis detergens ([oz]j-[oz]iv to oj), and liquor picis alkalinus ([dram]j-[dram]iv to oj), used cautiously. one or several ounces of alcohol and one or two drachms of glycerin in each pint of these lotions will often be of advantage, as the following:- [rx] ac. carbolici, ....................... [dram]j-[dram]iij gylcerinæ, ........................... f[dram]ij alcoholis, ........................... f[oz]ij aquæ, ......... q.s. ad .............. oj. m. various dusting-powders, alone or in conjunction with the lotions. and in some cases, especially those in which the skin is unnaturally dry, ointments may be used, such as equal parts of lard, lanolin, and petrolatum, to the ounce of which may be added from five to thirty grains of carbolic acid, three to twenty grains of thymol, ten to thirty minims of chloroform, or two to ten grains of menthol. #what external applications are to be used in the local varieties of pruritus?# in _pruritus ani_ and _pruritus vulvæ_, in addition to the various applications above, a cocaine ointment, one to ten grains to the ounce, a strong solution of the same (gr. v-xx to [oz]j), and an ointment containing ten to thirty minims of the oil of peppermint to the ounce; sponging with hot water, often affords temporary relief. in pruritus vulvæ, moreover, astringent applications and injections of zinc sulphate, alum, tannic or acetic acid, in the strength commonly employed for vaginal injections, are at times curative. in bath-pruritus weak glycerine lotions, and an ointment containing a few grains of thymol and menthol to the ounce sometimes give moderate relief. turkish baths are sometimes free from subsequent pruritus. #class viii.--parasitic affections.# #tinea favosa.# (_synonym:_ favus.) #what is tinea favosa?# tinea favosa, or favus, is a contagious vegetable-parasitic disease of the skin, characterized by pin-head to pea-sized, friable, umbilicated, cup-shaped yellow crusts, each usually perforated by a hair. #upon what parts and at what age is favus observed?# it is usually met with upon the scalp, but it may occur upon any part of the integument. occasionally the nails are invaded. it is seen at all ages, but is much more common in children. #describe the symptoms of favus of the scalp.# the disease begins as a superficial inflammation or hyperæmic spot, more or less circumscribed, slightly scaly, and which is soon followed by the formation of yellowish points about the hair follicles, surrounding the hair shaft. these yellowish points or crusts increase in size, become usually as large as small peas, are cup-shaped, with the convex side pressing down upon the papillary layer, and the concave side raised several lines above the level of the skin; they are umbilicated, friable, sulphur-colored, and usually each cup or disc is perforated by a hair. upon removal or detachment, the underlying surface is found to be somewhat excavated, reddened, atrophied and sometimes suppurating. as the disease progresses the crusting becomes more or less confluent, forming irregular masses of thick, yellowish, mortar-like crusts or accumulations, having a peculiar, characteristic odor--that of mice, or stale, damp straw. the hairs are involved early in the disease, become brittle, lustreless, break off and fall out. in some instances, especially near the border of the crusts, are seen pustules or suppurating points. _atrophy_ and more or less actual _scarring_ are sooner or later noted. itching, variable as to degree, is usually present. #what is the course of favus of the scalp?# persistent and slowly progressive. [illustration: fig. 66. achorion schönleinii x 450. (_after duhring._) showing simple mycelium, in various stages of development, and free spores.] #what are the symptoms of favus when seated upon the general surface?# the symptoms are essentially similar to those upon the scalp, modified somewhat by the anatomical differences of the parts. the _nails_, when affected, become yellowish, more or less thickened, brittle and opaque (_tinea favosa unguium_, _onychomycosis favosa_). #to what is favus due?# solely to the invasion of the cutaneous structures, especially the epidermal portion, by the vegetable parasite, the _achorion schönleinii_. it is contagious. it is a somewhat rare disease in the native-born, being chiefly observed among the foreign poor. the nails are rarely affected primarily. it is also met with in the lower animals, from which it is doubtless not infrequently communicated to man. #what are the diagnostic features of favus?# the yellow, and often cup-shaped, crusts, brittleness and loss of hair, atrophy, and the history. [illustration: fig. 67. epilating forceps.] #how would you distinguish favus from eczema and ringworm?# from eczema by the condition of the affected hair, the atrophic and scar-like areas, the odor, and the history. from ringworm by the crusting and the atrophy. in this latter disease there is usually but slight scaliness, and rarely any scarring. finally, if necessary, a microscopic examination of the crusts may be made. #state the method of examination for fungus.# a portion of the crust is moistened with liquor potassæ and examined with a power of three to five hundred diameters. the fungus, (achorion schönleinii), consisting of mycelium and spores, is luxuriant and is readily detected. #state the prognosis of favus.# upon the scalp, favus is extremely chronic and rebellious to treatment, and a cure in six to twelve months may be considered satisfactory; in neglected cases permanent baldness, atrophy, and scarring sooner or later result. although favus of the scalp persists into adult life, it becomes less active and, finally, as a rule, gradually disappears, leaving behind scarred or atrophic bald areas. upon the general surface it usually responds readily to treatment, excepting favus of the nails, which is always obstinate. #how is favus of the scalp treated?# treatment is entirely local and consists in keeping the parts free from crusts, in epilation and applications of a parasiticide. the crusts are removed by oily applications and soap-and-water washings. the hair on and around the diseased parts is to be kept closely cut, and, when practicable, depilation, or extraction of the affected hairs, is advised; this latter is, in most cases, essential to a cure. remedial applications--the so-called parasiticides--are, as a rule, to be made twice daily. if an ointment is used, it is to be thoroughly rubbed in; if a lotion, it is to be dabbed on for several minutes and allowed to soak in. #name the most important parasiticides.# corrosive sublimate, one to four grains to an ounce of alcohol and water; carbolic acid, one part to three or more parts of glycerine; a ten per cent. oleate of mercury; ointments of ammoniated mercury, sulphur and tar; and sulphurous acid, pure or diluted. the following is valuable:- [rx] sulphur, præcip., ....................

[oz]ss. m. chrysarobin is a valuable remedy, but must be used with caution; it may be employed as an ointment, five to ten per cent. strength, as a rubber plaster, or as a paint, a drachm to an ounce of gutta-percha solution. formalin, weakened or full strength, has been extolled. some observers have experimentally tried the effect of _x_-ray exposure with alleged good results, pushing the treatment to the point of producing depilation; if used great caution should be exercised. #how is favus upon the general surface to be treated?# in the same general manner as favus of the scalp, but the remedies employed should be somewhat weaker. in favus of the nail frequent and close paring of the affected part and the application, twice daily, of one of the milder parasiticides, will eventually lead to a good result. #is constitutional treatment of any value in favus?# it is questionable, but in debilitated subjects tonics, especially cod-liver oil, may be prescribed with the hope of aiding the external applications. #tinea trichophytina.# (_synonym:_ ringworm.) #what is tinea trichophytina?# tinea trichophytina, or ringworm, is a contagious, vegetable-parasitic disease due to the invasion of the cutaneous structures by the vegetable parasite, the trichophyton, or the microsporon audouinii. #do the clinical characters of ringworm vary according to the part affected?# yes, often considerably; thus upon the scalp, upon the general surface, and upon the bearded region, the disease usually presents totally different appearances. #describe the symptoms of ringworm as it occurs upon non-hairy portions of the body.# ringworm of the general surface (_tinea trichophytina corporis_, _tinea circinata_) appears as one or more small, slightly-elevated, sharply-limited, somewhat scaly, hyperæmic spots, with, rarely, minute papules, vesico-papules, or vesicles, especially at the circumference. the patch spreads in a uniform manner peripherally, is slightly scaly, and tends to clear in the centre, assuming a ring-like appearance. when coming under observation, the patches are usually from one-half to one inch in diameter, the central portion pale or pale red, and the outer portion more or less elevated, hyperæmic and somewhat scaly. as commonly noted one, several or more patches are present. after reaching a certain size they may remain stationary, or in exceptional cases may tend to spontaneous disappearance. at times when close together, several may merge and form a large, irregular, gyrate patch. itching, usually slight, may or may not be present. exceptionally ringworm appears as a markedly inflammatory pustular circumscribed patch, formerly thought to be a distinct affection and described under the name of _conglomerate pustular folliculitis_. it consists of a flat carbuncular or kerion-like inflammation, somewhat elevated, and usually a dime to silver dollar in area. the most common seats are the back of the hands and the buttocks. the surface is cribriform, and a purulent secretion may be pressed out from follicular openings. [illustration: fig. 68. tinea trichophytina cruris--so-called eczema marginatum--of unusually extensive development. (_after piffard._)] #describe the symptoms of ringworm when occurring about the thighs and scrotum.# in adults, more especially males, the inner portion of the upper part of the thighs and scrotum (_tinea trichophytina cruris_, so-called _eczema marginatum_) may be attacked, and here the affection, favored by heat and moisture, develops rapidly and may soon lose its ordinary clinical appearances, the inflammatory symptoms becoming especially prominent. the whole of this region may become involved, presenting all the symptoms of a true eczema; the border, however, is sharply defined, and usually one or more outlying patches of the ordinary clinical type of the disease may be seen. #describe the symptoms of ringworm when involving the nails.# in ringworm of the nails (_tinea trichophytina unguium_) these structures become soft or brittle, yellowish, opaque and thickened the changes taking place mainly about the free borders. ringworm on other parts usually coexists. #describe the symptoms of ringworm as it occurs upon the scalp.# ringworm of the scalp (_tinea trichophytina capitis_, _tinea tonsurans_) begins usually in the same manner as that upon the general surface, but, as a rule, much more insidiously. sooner or later, however, the hair and follicles are invaded by the fungus, and in consequence the hair falls out or becomes brittle and breaks off. the follicles, except in long-standing cases, are slightly elevated and prominent, and the patch may have a puffed or goose-flesh appearance. in addition, there is slight scaliness. #describe the appearances of a typical patch of ringworm of the scalp.# the patch is rounded, grayish, somewhat scaly, and slightly elevated; the follicles are somewhat prominent; there is more or less alopecia, with here and there broken, gnawed-off-looking hairs, some of which may be broken off just at the outlet of the follicles and more or less surrounded by a whitish or grayish-white dust. this type is produced by the small-spore fungus--microsporon. #does ringworm of the scalp always present typical appearances?# not invariably. in some cases the patch or patches may become almost completely bald, and in others a tendency to the formation of pustules, with more or less crust-formation, may be seen. the affection may also appear as small scattered spots or points. [illustration: fig. 69. ringworm (rather inflammatory type, and produced by the trichophyton).] the markedly inflammatory and pustular types are produced by the large-spore fungus--trichophyton. #what is tinea kerion?# tinea kerion (_kerion_) is a markedly inflammatory type of ringworm of the scalp involving the deeper tissues, appearing as a more or less bald, rounded, inflammatory, [oe]dematous, boggy, honeycombed tumor, discharging from the follicular openings a mucoid secretion. #does ringworm of the scalp ever occur in adults?# no. (extremely rare exceptions.) [illustration: fig. 70. ringworm fungus (trichophyton) x 450. (_after duhring._) as found in epidermic scrapings of ringworm, showing mycelium and spores.] #describe the symptoms of ringworm of the bearded region.# ringworm of the bearded region (_tinea trichophytina barbæ_, _tinea sycosis_, _parasitic sycosis_, _barber's itch_) begins usually in the same manner as ringworm on other parts, as one or more rounded, slightly scaly, hyperæmic patches. in rare instances the disease may persist as such, with very little tendency to involve the hairs and follicles; but, as a rule, the hairy structures are soon invaded, many of the hairs breaking off, and many falling out. from involvement of the follicles, more or less subcutaneous swelling ensues, the parts assuming a distinctly _lumpy and nodular_ condition. the skin is usually considerably reddened, often having a glossy appearance, and studded with few or numerous pustules. the nodules tend, ordinarily, to break down and discharge, at one or more of the follicular openings, a glairy, glutinous, purulent material, which may dry to thick, adherent crusts. [illustration: fig. 71. ringworm fungus (microsporon) x 500. (_after duhring._) short, broken-off hair of scalp invaded with masses of free spores.] the disease may be limited to one patch, or a large area, even to the extent of the whole bearded region, becomes involved. the upper lip is rarely invaded. ringworm of the bearded region is due to the trichophyton. [illustration: fig. 72. ringworm fungus (trichophyton) x 300. (_after duhring._) short, stout hair of beard, with the root-sheath attached, showing free spores and chains of spores.] #to what is ringworm due?# to the presence and growth in the cutaneous structures of a vegetable parasite. although the disease is contagious, individuals differ considerably as to susceptibility. it is much more common in children than in those past the age of puberty, ringworm of the scalp being limited to the former (rare exceptions), and tinea sycosis being a disease of the male adult. until recently the ringworm was thought to be due to but one fungus--the trichophyton; it is now known that there are several forms of fungi, the main forms being the small-spored (microsporon audouini) and the large-spored (trichophyton). of this latter there are two main subvarieties--endothrix and ectothrix. the small-spored fungus is found as the cause in the majority of scalp cases; the endothrix also commonly invades the scalp integument. the ectothrix variety is usually derived directly or indirectly from domestic animals, and is chiefly responsible for body-ringworm, and for suppurative ringworm, whether upon the bearded region or elsewhere. #what is the pathology of ringworm?# on the general surface the fungus has its seat in the epidermis, especially in the corneous layer; upon the scalp and bearded region the epidermis, hair-shaft, root and follicle are invaded. the inflammatory action may vary considerably in different cases, and at different times in the same case. the fungus consists of mycelium and spores. in the epidermic scrapings it is never to be found in abundance, and the mycelium predominates, while in affected hairs the spores and chains of spores are almost exclusively seen, and are usually present in great profusion. #how do you examine for the fungus?# the scrapings or hair should be moistened with liquor potassæ, and examined with a power from three hundred diameters upward. #how is ringworm of the general surface to be distinguished from eczema, psoriasis and seborrh[oe]a?# by the growth and characters of the patch, the slight scaliness, the tendency to disappear in the centre, by the history, and, if necessary, by a microscopic examination of the scales. #how is ringworm of the scalp to be distinguished from alopecia areata, favus, eczema, seborrh[oe]a, and psoriasis?# by the peculiar clinical features of ringworm on this region--the slight scaliness, broken hair and hair stumps, with a certain amount of baldness--and in doubtful cases by a microscopical examination of the hairs. in favus, although the same condition of the hair is noted, the yellow, cup-shaped crusts, and the presence of the atrophic areas in that disease are pathognomonic. #how is ringworm of the bearded region to be distinguished from eczema and sycosis?# by the peculiar lumpiness of the parts, the brittleness of the hair, more or less hair loss, and the history. the superficial type of ringworm sycosis--those cases in which the disease remains a surface disease--is readily distinguished, as the symptoms are essentially the same as ringworm of non-hairy parts, except that some of the hairs in the areas may become invaded and break off or fall out. in doubtful cases recourse may be had to microscopical examination. #what is the prognosis of ringworm of these several parts?# when upon the general surface, the disease usually responds rapidly to therapeutical applications; upon the scalp it is always a stubborn affection, and, as a rule, requires several months to a year of energetic treatment to effect a cure. in this latter region the disease will disappear spontaneously as the age of fifteen or sixteen is reached. tinea sycosis yields in most instances in the course of several weeks or a few months. #is ringworm of these several parts treated with the same remedies?# as a rule, yes; but the strength must be modified. the scalp will stand strong applications, as will likewise the bearded region; upon non-hairy portions the remedies should be used somewhat weaker. they should be applied twice daily; ointments, if used, being well rubbed in, and lotions thoroughly dabbed on. #how would you treat ringworm of the general surface?# by applications of the milder parasiticides, such as a ten to fifteen per cent. solution of sodium hyposulphite; carbolic acid, five to thirty grains to the ounce of water, or lard; a saturated solution of boric acid; ointments of tar, sulphur and mercury, official strength or weakened with lard; and tincture of iodine, pure or diluted. when occurring upon the upper and inner part of the thighs (so-called eczema marginatum), the same remedies are to be employed, but usually stronger. deserving of special mention is a lotion of corrosive sublimate, one to four grains to the ounce; or the same remedy, in the same proportion, may be used in tincture of myrrh or benzoin, and painted on the parts. #how would you treat ringworm of the scalp?# by occasional soap-and-hot-water washing; by extraction of the involved hairs, when practicable; by carbolic acid or boric acid lotions to the whole scalp, so as to limit, as much as possible, the spread of the disease; and by daily (or twice daily) applications to the patches and involved areas of a parasiticide. the following are the most valuable: the oleate of mercury, with lard or lanolin, in varying strength, from ten to twenty per cent.; carbolic acid, with one to three or more parts of glycerine or oil; corrosive sublimate, in solution in alcohol and water, one to four grains to the ounce; sulphur ointment; and citrine ointment, with one or two parts of lard. chrysarobin is a valuable remedy, but is to be employed with care; it may be prescribed as a rubber plaster, or in a solution of gutta-percha, or as an ointment, ten to fifteen per cent. strength. [beta]-naphthol in ointment form, five to fifteen per cent. strength, is also useful. an excellent application for beginning areas on the scalp is a solution of the red iodide of mercury in iodine tincture, one to three grains to an ounce. a compound ointment, containing several of the active remedies named, is convenient for dispensary practice, such as:- [rx] [beta]-naphthol, ................. [dram]ss-[dram]j ol. cadini, ......................... [dram]j ungt. sulphuris, ............ q.s. ad [oz]j. m. in that form known as tinea kerion mild applications are demanded at first; later the same treatment as in the ordinary type. #how is ringworm of the bearded region to be treated?# on the same general plan and with the same remedies (excepting chrysarobin) as in ringworm of the scalp. depilation is to be practised as an essential part of the treatment. special mention may be made of an ointment of oleate of mercury, sulphur ointment, a lotion of sodium hyposulphite ([dram]j-[oz]j), and a lotion of corrosive sublimate (gr. j-iv to [oz]j). the _x_-ray has been used in ringworm of this region with alleged success, pushing it to the production of a mild erythema and depilation. the above methods are, however, usually successful, and are without risk of damage. #how is the certainty of an apparent cure in ringworm of the scalp or bearded region to be determined?# by the continued absence of roughness and of broken hairs and stumps, and by microscopical examination of the new-growing hairs from time to time for several weeks after discontinuance of treatment. cure of ringworm of the general surface is usually self-evident. #is systemic treatment of aid in the cure of ringworm?# it is doubtful, although in children in a depraved state of health the disease is often noted to be especially stubborn, and in such cod-liver oil and similar remedies may at times prove of benefit. #tinea imbricata.# (_synonym:_ tokelau ringworm.) #what is tinea imbricata?# a vegetable parasitic disease of moist tropical countries, characterized by the formation of patches composed of concentrically arranged, imbricated, scaly rings. it may begin at one or several points as a brownish, slightly raised spot, spreading peripherally; the renewed epidermis of the central part of the patch goes again through the same process; the result is a small or large area of concentrically arranged, imbricated, slightly scaly eruption. several such areas fusing together may cover a large part of the surface, the ring-like arrangement being sometimes more or less completely lost. the malady is chronic. there may be a variable degree of itching. the cause of the disease, which is of a contagious nature, is a vegetable parasite closely similar to the trichophyton. the treatment is by the parasiticides, being essentially the same, in fact, as ringworm. #tinea versicolor.# (_synonyms:_ pityriasis versicolor; chromophytosis.) #what is tinea versicolor?# tinea versicolor is a vegetable-parasitic disease of the skin, characterized by variously-sized and shaped, slightly scaly, macular patches of a yellowish-fawn color, and occurring for the most part upon the upper portion of the trunk. #describe the symptoms of tinea versicolor.# the disease begins as one or more yellowish macular points; these, in the course of weeks or months, gradually extend, and, together with other patches that arise, may form a more or less continuous sheet of eruption. there is slight scaliness, always insignificant and furfuraceous in character, and at times, except upon close inspection, scarcely perceptible. the color of the patches is pale or brownish-yellow; in rare instances, in those of delicate skin, there may be more or less hyperæmia, and in consequence the eruption is of a reddish tinge. the number of patches varies; there may be but a few, or, on the other hand, a profusion. slight itching, especially when the parts are warm, is usually present. #does the eruption of tinea versicolor show predilection for any special region?# yes; the upper part of the trunk, especially anteriorly, is the usual seat of the eruption, but in exceptional instances the neck, axillæ, the arms, the whole trunk, the genitocrural region and poplitea, and in rare cases even the lower part of the face, may become invaded. #what course does tinea versicolor pursue?# persistent, but somewhat variable; as a rule, however, slowly progressive and lasting for years. #to what is tinea versicolor due?# to a vegetable fungus--the _microsporon furfur_. the affection is tolerably common, and occurs in all parts of the world. with rare exceptions, it is a disease of adults, and while looked upon as contagious, must be so to an extremely slight degree. [illustration: fig. 73. microsporon furfur x 400. (_after duhring._) showing mycelium in various stages of development, groups of spores and free spores.] #what is the pathology?# the fungus, consisting of mycelium and spores, the latter showing a marked tendency to aggregate, invades the superficial portion of the epidermis. #is tinea versicolor readily diagnosticated?# yes; if the color, peculiar characters and distribution of the eruption are kept in mind. it is not to be confounded with vitiligo, chloasma, or the macular syphiloderm. if in doubt, have recourse to the microscope. #state the method of examination for fungus.# the scrapings are taken from a patch, moistened with liquor potassæ, and examined with a power of three to five hundred diameters. #state the prognosis of tinea versicolor.# with proper management the disease is readily curable. relapses are not uncommon. [illustration: fig. 74. tinea versicolor.] #what is the treatment of tinea versicolor?# it consists in daily washing with soap and hot water (and in obstinate cases with sapo viridis instead of the ordinary soap) and application of a lotion of--sulphite or hyposulphite of sodium, a drachm to the ounce; sulphurous acid, pure or diluted; carbolic acid, or resorcin, ten to twenty grains to the ounce of water and alcohol; or corrosive sublimate, one to three grains to the ounce of water. sulphur and ammoniated-mercury ointments are also serviceable. the following used alone, simply as a soap, or in conjunction with a lotion, is often of special value:- [rx] sulphur, præcip., .................... [dram]iv saponis viridis, ..................... [dram]xii. m. after the disease is apparently cured, an occasional remedial application should be made for several months, in order to guard against the possibility of a relapse. #erythrasma.# #describe erythrasma.# erythrasma is an extremely rare disease, due to the presence and growth in the epidermic structures of the vegetable parasite--the _microsporon minutissimum_. it is characterized by small and large, slightly furfuraceous, reddish-yellow or reddish-brown patches, occurring usually on warm and moist parts, such as the axillary, inguinal, anal and genitocrural regions. it is slowly progressive and persistent, but is without disturbing symptoms other than occasional slight itching. [illustration: fig. 75. microsporon minutissimum x 1000. (_after riehl._)] treatment, which is rapidly effective, is the same as that employed in tinea versicolor. #dhobie itch.# dhobie itch is a name used in certain tropical countries to designate a somewhat peculiar itching eruption of the genitocrural and axillary regions, and by some also a similar eruption about the feet. it consists of a dermatitis of variable degree, usually with a festooned, irregular border, with considerable itching. it is believed that such cases are variously due to the trichophyton of ringworm, to the microsporon furfur of tinea versicolor, to the microsporon minutissimus of erythrasma, and to other parasites. #actinomycosis.# #describe actinomycosis.# actinomycosis of the skin is an affection due to the ray fungus, and characterized by a sluggish, red, nodular, or lumpy infiltration, usually with a tendency to break down and form sinuses. the affection may involve almost any part, but its most common site is about the jaw, neck, and face. as a rule, the first evidence is a hard subcutaneous swelling or infiltration, which may increase slightly or considerably. the overlying skin gradually becomes of a sluggish or dark-red color. softening ensues, and the diseased area breaks down at one or more points, from which there oozes a discharge of a sero-purulent, purulent, or sanguinolent character. in this discharge can be usually noted minute, friable, yellowish or yellowish-gray bodies representing conglomerate collections of the causative fungus. the course of the malady is commonly slow and insidious. unless systemic pyemic infection occurs or the fungus elements find their way to the deeper organs or structures the general health remains apparently undisturbed. #what is the treatment?# the administration of moderate to large doses of potassium iodide, conjointly with curetting or excision of the diseased mass. local applications of iodine solution can also be tried. #blastomycetic dermatitis.# #what do you understand by blastomycetic dermatitis?# blastomycetic dermatitis is a rare disease beginning usually as a small papule or nodule, enlarging slowly, breaking down and developing into a verrucous or papillomatous-looking area, similar in appearance to tuberculosis cutis verrucosa. a muco-purulent or purulent secretion can visually be pressed out from between the papillomatous elevations. it may also present the appearance of a serpiginous lupus vulgaris or syphiloderm. as a rule it is slow in its course. furuncular or abscess-like formations may develop, usually from secondary infection. the disease is due to the invasion of the cutaneous tissues by the blastomyces. [illustration: blastomycetic dermatitis.] treatment consists in administration of moderate to large doses of potassium iodide, and in the employment of antiseptic and parasiticide applications; usually, however, radical treatment, such as employed in lupus vulgaris, may be necessary. #scabies.# (_synonym:_ the itch.) #what is scabies?# scabies, or itch, is a contagious animal-parasitic disease characterized by a multiform eruption of a somewhat peculiar distribution, attended by intense itching. #describe the symptoms of scabies.# the penetration and presence of the parasites within the cutaneous structures besides often giving rise to several or more complete or imperfectly formed _burrows_, excite varying degrees of irritation, and in consequence the formation of vesicles, papules and pustules, accompanied with more or less intense itching. secondarily, crusting, and at times a mild or severe grade of dermatitis, may be brought about. the parasite seeks preferably tender and protected situations, as between the fingers, on the wrists, especially the flexor surface, in the folds of the axilla, on the abdomen, about the anal fissure, about the genitalia, and in females also about the nipples, and hence the eruption is most abundant about these regions. the inside of the thighs and the feet are also attacked, as, indeed, may be almost every portion of the body. the scalp and face are not involved; exceptionally, however, these parts are invaded in infants and young children. #is the grade of cutaneous irritation the same in all cases of scabies?# no; in those of great cutaneous irritability, especially in children, the skin being more tender, the type of the eruption is usually much more inflammatory. in those predisposed a true eczema may arise, and then, in addition to the characteristic lesions of scabies, eczematous symptoms are superadded; in long-persistent cases, indeed, the burrows and other consequent lesions may be more or less completely masked by the eczematous inflammation, and the true nature of the disease be greatly obscured. #what do you mean by burrows?# burrows, or _cuniculi_, are tortuous, straight or zigzag, dotted, slightly elevated, dark-gray or blackish thread-like linear formations, varying in length from an eighth to a half an inch. [illustration: fig. 76. burrow, or cuniculus, greatly magnified. (_after kaposi._) showing the mite, ova, empty shells and excrement.] #how is a burrow formed?# by the impregnated female parasite, which penetrates the epidermis obliquely to the rete, depositing as it goes along ten or fifteen ova, forming a minute passage or burrow. #upon what parts are burrows most commonly to be found?# in the interdigital spaces, on the flexor surface of the wrists, about the mammæ in the female, and on the shaft of the penis in the male. #are burrows usually present in numbers?# no. several may be found in a single case, but they are rarely numerous, as the irritation caused by the penetration of the parasites leads either to violent scratching and their destruction, or gives rise to the formation of vesicles and pustules, and consequently their formation is prevented. #what course does scabies pursue?# chronic and progressive, showing no tendency to spontaneous disappearance. #to what is scabies due?# to the invasion of the cutaneous structures by an animal parasite, the sarcoptes scabiei (_acarus scabiei_). the male mite is never found in the skin and apparently takes no direct part in the production of the symptoms. [illustration: fig. 77. fig. 78. sarcoptes scabiei x 100. (_after duhring._) female. ventral surface. male.] the disease is contagious to a marked degree, and is most commonly contracted by sleeping with those affected, or by occupying a bed in which an affected person has slept. it occurs, for obvious reasons, usually among the poor, although it is now quite frequently met with among the better classes. #state the diagnostic features of scabies.# the burrows, the peculiar distribution and the multiformity of the eruption, the progressive development, and usually a history of contagion. #how do vesicular and pustular eczema differ from scabies?# eczema is usually limited in extent, or irregularly distributed, is distinctly patchy, with often the formation of large diffused areas; it is variable in its clinical behavior, better and worse from time to time, and differs, moreover, in the absence of burrows and of a history of contagion. #how does pediculosis corporis differ from scabies?# in the distribution of the eruption. the pediculi live in the clothing and go to the skin solely for nourishment, and hence the eruption in that condition is upon covered parts, especially those parts with which the clothing lies closely in contact, as around the neck, across the upper part of the back, about the waist and down the outside of the thighs; _the hands are free_. #state the prognosis of scabies.# it is favorable. the disease is readily cured, and, as soon as the parasites and their ova are destroyed, the itching and the secondary symptoms, as a rule, rapidly disappear. #how is scabies treated?# treatment is entirely external, and consists of a preliminary soap-and-hot-water bath, an application, twice daily for three days, of a remedy destructive to the parasites and ova, and finally another bath. inquiry as to others of the family should be made, and, if affected, treated at the same time. the wearing apparel should be looked after--boiled, baked, or sulphur-fumigated. #what remedial applications are employed in scabies?# sulphur, balsam of peru, styrax, and [beta]-naphthol, singly or severally combined. in children, or in those of sensitive skin, the following:- [rx] sulphur. præcip., .................... [dram]iv balsam. peruv., ...................... [dram]ij adipis, petrolati, ......... [=a][=a] ........ [oz]iss. m. and in adults, or those of non-irritable skin:- [rx] sulphur, præcip., .................... [oz]j balsam. peruv., ...................... [oz]ss [beta]-naphthol, ..................... [dram]ij adipis, petrolati, ... [=a][=a] ... q.s. ad .. [oz]iv. m. styrax is a remedy of value and is commonly employed as an ointment in the strength of one part to two or three parts of lard. #is one such course of treatment sufficient to bring about a cure?# yes, in ordinary cases, if the applications have been carefully and thoroughly made; exceptionally, however, some parasites and ova escape destruction, and consequently itching will again begin to show itself at the end of a week or ten days, and a repetition of the treatment become necessary. #does the secondary dermatitis which is always present in severe cases require treatment?# only when it is unusually persistent or severe; in such cases the various soothing applications, lotions or ointments employed in acute eczema are to be prescribed. #is a dermatitis due to too active and prolonged treatment ever mistaken for persistence of the scabies?# yes. #pediculosis.# (_synonyms:_ phtheiriasis; lousiness.) #define pediculosis.# pediculosis is a term applied to that condition of local or general cutaneous irritation due to the presence of the animal parasite, the pediculus, or louse. #name the several varieties met with.# three varieties are presented, named according to the parts involved, pediculosis capitis, pediculosis corporis, and pediculosis pubis; the parasite in each being a distinct species of pediculus. #pediculosis capitis.# #describe the symptoms of pediculosis capitis.# pediculosis capitis (_pediculosis capillitii_), due to the presence of the pediculus capitis, occurs much more frequently in children than in adults. it is characterized by marked itching, and the formation of various inflammatory lesions, such as papules, pustules and excoriations--resulting from the irritation produced by the parasites and from the scratching to which the intense pruritus gives rise. in fact, an eczematous eruption of the pustular type soon results, attended with more or less crust formation. in consequence of the cutaneous irritation the neighboring lymphatic glands may become inflamed and swollen, and in rare cases suppurate. the occipital region is the part which is usually most profusely infested, more especially in young girls and women. in those of delicate skin, especially in children, scattered papules, vesico-papules, pustules, and excoriations may often be seen upon the forehead and neck. in some instances, however, especially in boys, there may be many pediculi present, with but little cutaneous disturbance, the itching being the sole symptom. [illustration: fig. 79. pediculus capitis x 25. (_after duhring._) female. dorsal surface.] in addition to the pediculi, which, as a rule, may be readily found, their _ova_, or _nits_, are always to be seen upon the shaft of the hairs, quite firmly attached. #describe the appearance of the ova.# they are dirty-white or grayish looking, minute, pear-shaped bodies, visible to the naked eye, and fastened upon the shaft of the hairs with the small end toward the root. [illustration: fig. 80. ova of the head-louse attached to a hair. magnified. (_after kaposi._)] #is there any difficulty in the diagnosis of pediculosis capitis?# no. the diagnosis is readily made, as the pediculi are usually to be found without difficulty, and even when they exist in small numbers and are not readily discovered, _the presence of the ova_ will indicate the nature of the affection. pustular eruptions upon the scalp, especially posteriorly, should always arouse a suspicion of pediculosis. the possibility of the pediculosis being secondary to eczema must not be forgotten. #what is the treatment of pediculosis capitis?# treatment consists in the application of some remedy destructive to the pediculi and their ova. crude petroleum is effective, one or two thorough applications over night being usually sufficient; in order to lessen its inflammability, and also to mask its somewhat disagreeable odor, it may be mixed with an equal part of olive oil and a small quantity of balsam of peru added. tincture of cocculus indicus, pure or diluted, may also be applied with good results. when the parts are markedly eczematous, an ointment of ammoniated mercury or [beta]-naphthol, thirty to sixty grains to the ounce may be used. daily shampooing with soap and water, and the twice daily application of a five per cent. carbolic acid lotion, together with the use of a fine-toothed comb, is a safe and efficient method for dispensary practice; as it is, indeed, for any class of patients. #how are the ova or their shells to be removed from the hair?# by the frequent use of acid or alkaline lotions, such as dilute acetic acid and vinegar, or solutions of sodium carbonate and borax. #pediculosis corporis.# #describe the symptoms of pediculosis corporis.# pediculosis corporis is dependent upon the presence of the pediculus corporis (_pediculus vestimenti_), a larger variety than that infesting the scalp. it is characterized by more or less general itching, together with various inflammatory lesions and excoriations. as the parasites are to be found chiefly in the folds and seams of the clothing, visiting the skin for the purpose of feeding, the various symptoms--the minute hemorrhagic puncta showing the points at which they have been sucking, and the consequent papules, pustules and excoriations--are, therefore, to be found most abundantly on those parts with which the clothing comes closely in contact, as, for instance, around the neck, across the shoulders, around the waist, and down the outside of the thighs. it is uncommon in children. [illustration: fig. 81. pediculus corporis x 25. (_after duhring._) female. dorsal surface.] #state the diagnostic characters of pediculosis corporis.# the presence of the minute hemorrhagic puncta, the multiform character and peculiar distribution of the eruption. careful search will almost invariably disclose one or more pediculi. #what is the treatment of pediculosis corporis?# the clothing and bed-coverings are to be thoroughly baked or boiled, the pediculi and their ova being in this manner destroyed; a thymol or carbolized boric-acid lotion may be used to relieve the cutaneous irritation. when attention to the wearing apparel is not immediately practicable, ointments of sulphur and staphisagria, and lotions of carbolic acid, may be advised as temporary measures. the wearing of a bag of loosely woven texture containing some lump sulphur next to the skin is useful in such cases; at the temperature of the body the sulphur undergoes slow oxidation. in hairy individuals the malady is often persistent, due to the fact that ova have become attached to the hair and a new progeny soon hatched out. continued treatment over a few weeks will usually suffice to rid the patient of their presence. #pediculosis pubis.# #describe the symptoms of pediculosis pubis.# pediculosis pubis is a condition due to the presence of the pediculus pubis, or crab-louse. it is characterized by more or less itching about the genitalia, together with papules, excoriations, and other inflammatory lesions. the amount of irritation varies; it may be slight, or, on the other hand, severe. the parasite, which is the smallest of the three varieties, may be discovered upon close examination seated near the roots of the hairs, clutching the hair, with its head downward and buried in the follicle. the ova may be seen attached to the hair-shafts. it infests adults chiefly, being in many instances probably contracted through sexual intercourse. #is the pediculus pubis found upon any other part of the body?# yes. although its favorite habitat is the region of the pubes, it may, in exceptional instances, also infest the axillæ, the sternal region of the male, the beard, eyebrows, and even the eyelashes. #state the diagnostic characters of pediculosis pubis.# the region involved, itching, variable amount of irritation, and, above all, the presence of the pediculi and their ova. [illustration: fig. 82. pediculus pubis x 25. (_after duhring._) female. dorsal surface.] #name several applications prescribed for pediculosis pubis.# a lotion of corrosive sublimate, one to four grains to the ounce; infusion of tobacco; a ten to twenty per cent. ointment of oleate of mercury; ammoniated mercury ointment, and a five to ten per cent. [beta]-naphthol ointment. repeated washings with vinegar or dilute acetic acid, or with alkaline lotions, will free the hairs of the ova. #cysticercus cellulosæ.# #describe the cutaneous disturbance produced by the cysticercus cellulosæ.# the presence of cysticerci in the skin and subcutaneous tissue gives rise to pea to hazelnut-sized, rounded, firm, movable tumors which, when developed, may remain unchanged for months. the parasites are disclosed by microscopic examination. most of the cases have been observed in germany. #filaria medinensis.# (_synonym:_ guinea-worm.) #state the character of the lesions produced by the filaria medinensis.# the young microscopic worm penetrates the skin or deeper tissue, where it grows gradually, finally reaching several inches or more in length and about a half-line in thickness; inflammation is excited and a tumor-like swelling makes its appearance, which, sooner or later, breaks, disclosing the worm. it may also present a cord-like appearance. it is rarely met with outside of tropical countries. treatment consists in gradual extraction, or in the injection of a corrosive sublimate solution (1:1000) into the forming tumor. asafetida internally has been found to be curative, the parasite being destroyed and subsequently absorbed or discharged. #ixodes.# (_synonym:_ wood-tick.) #state the character of the cutaneous disturbance produced by the ixodes.# the tick sticks its proboscis into the skin and sucks blood until it is several times its natural size, and then falls off; an urticarial lesion results. if caught in the act the animal should not be forcibly extracted, as its proboscis may be thus broken off and remain in the skin, and give rise to pain and inflammation. it may be made to relinquish its hold by placing on it a drop of an essential oil. a thymol or carbolized boric-acid lotion will relieve the irritation. #leptus.# (_synonym:_ harvest-mite.) #state the characters of the lesion produced by the leptus.# this minute brick-red mite buries itself in the skin, especially about the ankles and feet, giving rise to papules, vesicles and pustules. treatment consists of the use of a mild sulphur ointment or of a carbolic-acid lotion. #[oe]strus.# (_synonym:_ gad, or bot-fly.) #describe the cutaneous disturbance produced by the [oe]strus.# the ova are deposited in the skin, develop and give rise to the formation of furuncle-like tumors with central aperture, through which a sanious discharge exudes; or as the result of the burrowing of the larvæ, irregular serpiginous lines or wheals are produced. it is chiefly met with in central and south america. _larva migrant_, or _creeping disease_, is doubtless in this same class. it is characterized by a thread-like linear formation of an erythematous, erythemato-papular, or vesicular nature that gradually extends, the older part disappearing; considerable surface may be covered before the parasite disappears or dies. the treatment consists in endeavoring to destroy the organism by means of excision or caustic applications at the point of its suspected site which is just ahead of the extending line. #pulex penetrans.# (_synonyms:_ sand flea; jigger.) #describe the cutaneous disturbance produced by the pulex penetrans.# this microscopic animal penetrates the skin, especially about the toes, producing an inflammatory swelling, vesicle or pustule, or even ulceration. it is met with in warm and tropical countries. treatment consists in extraction. essential oils are used as a preventive. a carbolic-acid or alkaline lotion relieves irritation. #cimex lectularius.# (_synonym:_ bed-bug.) #describe the characters of a bed-bug bite.# an inflammatory papule or wheal-like lesion results, somewhat hemorrhagic; the purpuric or hemorrhagic point or spot remains after the swelling subsides, but finally, in the course of several days or a few weeks, disappears. treatment consists in the application of alkaline or acid lotions. #culex.# (_synonym:_ gnat; mosquito.) #describe the cutaneous disturbance produced by the culex.# it consists of an erythematous spot or a wheal-like lesion. alkaline or acid lotions usually give relief. #pulex irritans.# (_synonym:_ common flea.) #describe the cutaneous disturbance produced by the pulex irritans.# it consists of an erythematous spot with a minute central hemorrhagic point. in irritable skin, a wheal-like lesion may result. treatment consists of applications of camphor or ammonia-water; carbolic acid and thymol lotions are also useful. relative

========================================================================= saunders' text-books continue to gain the list of text-books recommended in the various colleges again shows a #decided gain for the saunders publications#. during the present college year, in the list of recommended books published by 164 colleges (the other 23 have not published lists), the saunders books are mentioned 3278 times, as against 3054 the previous year--#an increase of 224#. in other words, in each of the medical colleges in this country an average of 20 (18-2/5 the previous year) of the teaching books employed are publications issued by w. b. saunders company. that this increase is not due alone to the publication of new text-books, but rather to a most gratifying increase in the recommendation of text-books recognized as standards, is at once evident from the following: ashton's gynecology shows an increase of 19; dacosta's surgery, an increase of 12; hirst's obstetrics, 14; howell's physiology, 25; jackson on the eye, 16; sahli's diagnostic methods, 11; scudder's fractures, 11; stengel's pathology, 13; stelwagon on the skin, 11. these are but examples of similar remarkable gains throughout the entire list, and is undoubted evidence that the #saunders text-books are recognized as the best#. #a complete catalogue of our publications will be sent upon request# bandler's medical gynecology * * * * * #medical gynecology#. by s. wyllis bandler, m.d., adjunct. professor of diseases of women, new york post-graduate medical school and hospital. octavo of 680 pages, with 135 original illustrations. cloth, $5.00 net; half morocco, $6.50 net. #just ready--exclusively medical gynecology# this new work by dr. bandler is just the book that the physician engaged in general practice has long needed. it is truly _the practitioner's gynecology_--planned for him, written for him, and illustrated for him. there are many gynecologic conditions that do not call for operative treatment; yet, because of lack of that special knowledge required for their diagnosis and treatment, the general practitioner has been unable to treat them intelligently. this work gives just the information the practitioner needs. it not only deals with those conditions amenable to non-operative treatment, but it also tells how to recognize those diseases demanding operative treatment, so that the practitioner will be enabled to advise his patient at a time when operation will be attended with the most favorable results. the chapter on pessaries is especially full and excellent, the proper manner of introducing the pessary being clearly described and illustrated with original pictures that show plainly the correct technic of this procedure. the chapters on vaginal and abdominal massage, and particularly that on artificial hyperemia and anemia, are extremely valuable to the practitioner. they express the very latest advances in these methods of treatment. hydrotherapy, especially the ferguson and nauheim baths, are treated _in extenso_, and electrotherapy receives the full consideration its importance merits. pain as a symptom and its alleviation is dealt with in an unusually practical way, its value as an aid in diagnosis being emphasized. gonorrhea and syphilis and their many complications are treated in detail, every care being taken to have these sections--of special interest to the practitioner--complete in every particular. other chapters of great importance are those on constipation, sterility, associated nervous conditions in gynecology, and pregnancy and abortion. kelly and noble's gynecology and abdominal surgery #gynecology and abdominal surgery#. edited by howard a. kelly, m.d., professor of gynecology in johns hopkins university; and charles p. noble, m.d., clinical professor of gynecology in the woman's medical college, philadelphia. two imperial octavo volumes of 900 pages each, containing 650 illustrations, mostly original. per volume: cloth, $8.00 net; half morocco, $9.50 net. both volumes now ready with 650 original illustrations by hermann becker and max brödel in view of the intimate association of gynecology with abdominal surgery the editors have combined these two important subjects in one work. for this reason the work will be doubly valuable, for not only the gynecologist and general practitioner will find it an exhaustive treatise, but the surgeon also will find here the latest technic of the various abdominal operations. it possesses a number of valuable features not to be found in any other publication covering the same fields. it contains a chapter upon the bacteriology and one upon the pathology of gynecology, dealing fully with the scientific basis of gynecology. in no other work can this information, prepared by specialists, be found as separate chapters. there is a large chapter devoted entirely to _medical gynecology_, written especially for the physician engaged in general practice. heretofore the general practitioner was compelled to search through an entire work in order to obtain the information desired. _abdominal surgery_ proper, as distinct from gynecology, is fully treated, embracing operations upon the stomach, upon the intestines, upon the liver and bile-ducts, upon the pancreas and spleen, upon the kidney, ureter, bladder, and the peritoneum. special attention has been given to _modern technic_ and illustrations of the very highest order have been used to make clear the various steps of the operations. indeed, the illustrations are truly magnificent, being the work of _mr. hermann becker_ and _mr. max brödel_, of the johns hopkins hospital. ashton's practice of gynecology * * * * * #the practice of gynecology#. by w. easterly ashton,

flushing, hirst's treatment for vaginismus, dudley's treatment of cystocele, montgomery's round ligament operation, chorio-epithelioma of the uterus, passive incontinence of the urine, and moynihan's methods in intestinal anastomosis. nothing is left to be taken for granted, the author not only telling his readers in every instance what should be done, but also precisely _how to do it_. a distinctly original feature of the book is the illustrations, numbering about one thousand line drawings made especially under the author's personal supervision from actual apparatus, living models, and dissections on the cadaver. these line drawings show in detail the procedures and operations without obscuring their purpose by unnecessary and unimportant anatomic surroundings. #howard a. kelly, m.d.# _professor of gynecology, johns hopkins university._ "it is different from anything that has as yet appeared. the illustrations are particularly clear and satisfactory. one specially good feature is the pains with which you describe so many _details_ so often left to the imagination." #charles b. penrose, m.d.,# _formerly professor of gynecology, university of pennsylvania._ "i know of no book that goes so thoroughly and satisfactorily into all the _details_ of everything connected with the subject. in this respect your book differs from the others." #george m. edebohls, m.d.#

and in thousands of cases of war neuroses as reported by smith and pear, eder, maccurdy, and other military observers. these army experts have shown that shell-shock in war is the same as nervousness in civil life and that both may be cured by psycho-analysis and re-education. for more than a decade, in handling nervous cases, i have made use of the findings of recognized authorities on psychopathology. truths have been applied in a special way, with the features of re-education so emphasized that my home has been called a psychological boarding-school. as the alumni have gone back to the game of life with no haunting memories of usual sanatorium methods, but with the equipment of a fuller self-knowledge and sense of power, they have sent back a call for some word that shall extend this helpful message to a larger circle. there has come, too, a demand for a book which shall give accurate and up-to-date information to those physicians who are eager for light on the subject of nervous disorders, and especially for knowledge of the significant contributions of sigmund freud, but who are too busy to devote time to highly technical volumes outside their own specialties. this need for a simple, comprehensive presentation of the freudian principles i have attempted to meet in this primer of psychotherapy, providing enough of biological and psychological background to make them intelligible, and enough application and illustration to make them useful to the general practitioner or the average layman. josephine a. jackson. pasadena, california, 1921. contents part i: the strange ways of nerves chapter i page in which most of us plead guilty to the charge of "nerves." nervous folk 3 chapter ii in which we learn what "nerves" are not and get a hint of what they are. the drama of nerves 10 part ii: "how the wheels go round" chapter iii in which we find a goodly inheritance. the story of the instincts 33 chapter iv in which we learn more about ourselves. the story of the instincts (continued) 51 chapter v in which we look below the surface and discover a veritable wonderland. the subconscious mind 77 chapter vi in which we learn why it pays to be cheerful. body and mind 118 chapter vii in which we go to the root of the matter. the real trouble 141 part iii: the mastery of "nerves" chapter viii in which we pick up the clue. the way out 183 chapter ix in which we discover new stores of energy and relearn the truth about fatigue. that tired feeling 219 chapter x in which the ban is lifted. dietary taboos 250 chapter xi in which we learn an old trick. the bugaboo of constipation 278 chapter xii in which handicaps are dropped. a woman's ills 300 chapter xiii in which we lose our dread of night. that interesting insomnia 322 chapter xiv in which we raise our thresholds. feeling our feelings 333 chapter xv in which we learn discrimination. choosing our emotions 359 chapter xvi in which we find new use for our steam. finding vent in sublimation 379 glossary 386 bibliography 390 index 393 outwitting our nerves chapter i _in which most of us plead guilty to the charge of "nerves."_ nervous folk who's who whenever the subject of "nerves" is mentioned most people begin trying to prove an alibi. the man who is nervous and knows that he is nervous, realizes that he needs help, but the man who has as yet felt no lack of stability in himself is quite likely to be impatient with that whole class of people who are liable to nervous breakdown. it is therefore well to remind ourselves at once that the line between the so-called "normal" and the nervous is an exceedingly fine one. "nervous invalids and well people are indistinguishable both in theory and in practice,"[1] and "after all we are most of us more or less neurasthenic."[2] the fact is that everybody is a possible neurotic. [footnote 1: putnam: _human motives_, p. 117.] [footnote 2: dubois: _physic treatment of nervous disorders_, p. 172.] so, as we think about nervous folk and begin to recognize our friends and relatives in this class, it may be that some of us will unexpectedly find ourselves looking in the mirror. some of our lifelong habits may turn out to be nervous tricks. at any rate, it behooves us to be careful about throwing stones, for most of us live in houses that are at least part glass. the earmarks =am i "like folks"?= before we begin to talk about the real sufferer from "nerves," the nervous invalid, let us look for some of the earmarks that are often found on the supposedly well person. all of these signs are deviations from the normal and are sure indications of nervousness. the test question for each individual is this: "am i 'like folks'?" to be normal and to be well is to be "like folks." can the average man stand this or that? if he can, then you are not normal if you cannot. do the people around you eat the thing that upsets you? if they do, ten chances to one your trouble is not a physical idiosyncrasy, but a nervous habit. in bodily matters, at least, it is a good thing to be one of the crowd. many people who would resent being called anything but normal--in general--are not at all loth to be thought "different," when it comes to particulars. are there not many of us who are at small pains to hide the fact that we "didn't sleep a wink last night," or that we "can't stand" a ticking clock or a crowing rooster? we sometimes consider it a mark of distinction to have a delicate appetite and to have to choose our food with care. if we are frank with ourselves, some of us will have to admit that our own ailments seem interesting, while the other person's ills are "merely nervous" or imaginary or abnormal. after all, a good many of us will have to plead guilty to the charge of nervousness. we have only to read the endless advertisements of cathartics and "internal baths," or to check up the quantity of laxatives sold at any drug store, to realize the wide-spread bondage to that great bugaboo constipation. he who is constipated can hardly prove an alibi to "nerves." then there are the school-teachers and others who are worn out at the end of each year's work, hardly able to hold on until vacation; and the people who can't manage their tempers; and those who are upset over trifles; and those who are dissatisfied with life. to a certain degree, at least, all of these are nervous persons. the list grows. =half-power engines.= these people are all supposed to be well. they keep going--by fits and starts--and as they are used to running on three cylinders, with frequent stops for repairs, they accept this rate of living as a matter of course, never realizing that they might be sixty horse-power engines, instead of their little thirty or forty. for this large and neglected class of people psychotherapy has a stimulating message, and for them many of the following pages have been written. =the real sufferers.= these so-called normal people are merely on the fringe of nervousness, on the border line between normality and disease. beyond them there exists a great company of those whose lives have been literally wrecked by "nerves." their work interrupted or given up for good, their minds harassed by doubts and fears, their bodies incapacitated, they crowd the sanatoria and the health resorts in a vain search for health. from new england to florida they seek, and on to colorado and california, and perhaps to hawaii and the orient, thinking by rest and change to pull themselves together and become whole again. there are thousands of these people--lawyers, preachers, teachers, mothers, social workers, business and professional folk of all sorts, the kind of persons the world needs most--laid off for months or years of treatment, on account of some kind of nervous disorder. =various types of nervousness.= the psychoneuroses are of many forms.[3] to some people "nerves" means nervous prostration, breakdown, fatigue, weakness, insomnia, the blues, upset stomach, or unsteady heart,--all signs of so-called neurasthenia or nerve-weakness. to others the word "nerves" calls up memories of strange, emotional storms that seem to rise out of nowhere, to sweep the sky clear of everything else, and to pass as they came, leaving the victim and the family equally mystified as to their meaning. these strange alterations of personality are but one manifestation of hysteria, that myriad-faced disorder which is able to mimic so successfully the symptoms of almost every known disease, from tumors and fevers to paralysis and blindness. [footnote 3: the technical term for nervousness is _psycho-neurosis_--disease of the psyche. there are certain "real neuroses" such as paralysis and spinal-cord disease, which involve an organic impairment of nerve-tissue. however, as this book deals only with psychic disturbance, we shall, throughout, use the term _neuroses_ and _psycho-neuroses_ indiscriminately, to denote nervous or functional disorders.] to still other people nervous trouble means fear,--just terrible fear without object or meaning or reason (anxiety neuroses); or a definite fear of some harmless object (phobia); or a strange, persistent, recurrent idea, quite foreign to the personality and beyond the reach of reason (obsession); or an insistent desire to perform some absurd act (compulsion); or perhaps, a deadly and pall-like depression (the blues). as a matter of fact, the neuroses include all these varieties, and various shades and combinations of each. there are, however, certain mental characteristics which recur with surprising regularity in most of the various phases--dissatisfaction, lack of confidence, a sense of being alone and shut in to oneself, doubt, anxiety, fear, worry, self-depreciation, lack of interest in outside affairs, pessimism, fixed belief in one's powerlessness, along whatever line it may be. underneath all these differing forms of nervousness are the same mechanisms and the same kind of difficulty. to understand one is to understand all, and to understand normal people as well; for in the last analysis we are one and all built on the same lines and governed by the same laws. the only difference is, that, as jung says, "the nervous person falls ill of the conflicts with which the well person battles successfully." summary since at least seventy-five per cent. of all the people who apply to physicians for help are nervous patients; and since these thousands of patients are not among the mental incompetents, but are as a rule among the highly organized, conscientious folk who have most to contribute to the leadership of the world, it is obviously of vital importance to society that its citizens should be taught how to solve their inner conflicts and keep well. in this strategic period of reconstruction, the world that is being remodeled cannot afford to lose one leader because of an unnecessary breakdown. there is greater need than ever for people who can keep at their tasks without long enforced rests; people who can think deeply and continuously without brain-fag; people who can concentrate all their powers on the work in hand without wasting time or energy on unnecessary aches and pains; people whose bodies are kept up to the top notch of vitality by well-digested food, well-slept sleep, well-forgotten fatigue, and well-used reserve energy. that such a state of affairs is no utopian dream, but is merely a matter of knowing how, will appear more clearly in later chapters. chapter ii _in which we learn what "nerves" are not, and get a hint of what they are_ the drama of nerves an exploded theory ="nerves" not nerves.= pick up any newspaper, turn over a few pages, and you will be sure to come to an advertisement something like this: tired man, your nerves are sick! they need rest and a tonic to restore their worn-out depleted cells! no wonder people have believed this kind of thing. it has been dinned into their ears for many years. they have read it with their breakfast coffee and gazed at it in the street cars and even heard it from their family physicians, until it has become part and parcel of their thinking; yet all the time the fundamental idea has been false, and now, at last, the theory is exploded. so far as the modern laboratory can discover, the nerves of the most confirmed neurotic are perfectly healthy. they are not starved, nor depleted, nor exhausted; the fat-sheath is not wanting, there is no inflammation, there is nothing lacking in the cell itself, and there is no accumulation of fatigue products. paradoxical as it may sound, there is nothing the matter with a nervous person's nerves. the faithful messengers have borne the blame for so long that their name has gotten itself woven into the very language as symbolic of disease. when we speak of nervous prostration, neurasthenia, neuroses, nervousness, and "nerves" we mean that body and mind are behaving badly because of functional disorder. these terms are good enough as figures of speech, so long as we are not fooled by them; but accepting them in their literal sense has been a costly procedure. thanks to the investigations of physiologist and psychologist, usually combined in the person of a physician, "nervousness" has been found to be not an organic disease but a functional one. this is a very important distinction, for an organic disease implies impairment of the tissues of the organ, while a functional disorder means only a disturbance of its action. in a purely nervous disorder there seems to be no trouble with what the nerves and organs are, but only with what they do; it is behavior and not tissue that is at fault. of course, in real life, things are seldom as clear-cut as they are in books, and so it happens that often there is a combination of organic and functional disease that is puzzling even to a skilled diagnostician. the first essential is a diagnosis as to whether it be an organic disease, with accompanying nervous symptoms, or a functional disturbance complicated by some minor organic trouble. if the main cause is organic, only physical means can cure it, but if the trouble is functional, no amount of medicine or surgery, diet or rest, will touch it; yet the symptoms are so similar and the dividing line is so elusive, that great skill is sometimes required to determine whether a given symptom points to a disturbance of physical tissue or only to behavior. if the physician is sometimes fooled, how much more the sufferer himself! nausea from a healthy stomach is just as sickening as nausea from a diseased one. a fainting-spell is equally uncomfortable, whether it come from an impaired heart or simply from one that is behaving badly for the moment. it must be remembered that in functional nervousness the trouble is very real. the organs are really "acting up." sometimes it is the brain that misbehaves instead of the stomach or heart. in that case it often reports all kinds of pains that have no origin outside of the brain. pain, of course, is perceived only by the brain. cut the telegraph wire, the nerve, and no amount of injury to the finger can cause pain. it is equally true that a misbehaving brain can report sensations that have no external cause, that have not come in through the regular channel along the nerve. the pain feels just the same, is every bit as uncomfortable as though its cause were external. sometimes, instead of reporting false pains, the brain misbehaves in other ways. it seems to lose its power to decide, to concentrate, or to remember. then the patient is almost sure to fancy himself going insane. but insanity is a physical disease, implying changes or toxins in the brain cells. functional disorders tell another story. their cause is different, even though the picture they present is often a close copy of an organic disease. =distorted pictures.= it should not be thought, however, that the symptoms of functional and organic troubles are identical. hysteria and neurasthenia closely simulate every imaginable physical disease, but they do not exactly parallel any one of them. it may take a skilled eye to discover the differences, but differences there are. functional troubles usually show a near-picture of organic disease, with just enough contradictory or inconsistent features to furnish a clue as to their real nature. for this reason it is important that the treatment of the disease be solely the province of the physician; for only the carefully trained in all the requirements of diagnosis can differentiate the pseudo from the real, the innocuous from the disastrous. false or nervous neuritis may feel like real neuritis (the result of poisons in the blood), but it gives itself away when it localizes itself in parts of the body where there is no nerve trunk. the exhaustion of neurasthenia sometimes seems extreme enough to be the result of a dangerous physical condition; but when this exhaustion disappears as if by magic under the proper kind of treatment, we know that the trouble cannot be in the body. let it be said, then, with all the emphasis we can command, "nerves" are not physical. laboratory investigation, contradictory symptoms, and response to treatment all bear witness to this fact. whatever symptoms of disturbance there may be in pure nervousness, the nerves and organs can in no way be shown to be diseased. the positive side ="nerves" not imaginary.= "but," some one says, "how can healthy organs misbehave in this way? something must be wrong. there must be some cause. if 'nerves' are not physical, what are they? they surely can't be imaginary." most emphatically, they are real; nothing could be more maddening than to have some one suggest that our troubles are "mere imagination." no wonder such theories have been more popular with the patient's family than with the patient himself. many years ago a physician put the whole truth into a few words: "the patient says, 'i cannot'; his friends say, 'he will not'; the doctor says, 'he cannot will.'" he tries, but in the circumstances he really cannot. =the man behind the body.= the trouble is real; the organs do "act up"; the nerves do carry the wrong messages. but the nerves are merely telegraph wires. they are not responsible for the messages that are given them to carry. behind the wires is the operator, the man higher up, and upon him the responsibility falls. in functional troubles the body is working in a perfectly normal way, considering the perverted conditions. it is doing its work well, doing just what it is told, obeying its master. the troubles are not with the bodily machine but with the master. the man behind the body is in trouble and he really has no way of showing his pain except through his body. the trouble in nervous disorders is in the personality, the soul, the realm of ideas, and that is not your body, but _you_. loss of appetite may mean either that the powers of the physical organism are busily engaged in combating some poison circulating in the blood, or that the ego is "up against" conditions for which it has "no stomach." paralysis may be due to a hemorrhage into the brain tissues from a diseased blood vessel, or it may symbolize a sense of inadequacy and defeat. exaggerated exhaustion, halting feet, stammering tongue, may give evidence of a disturbed ego rather than of a diseased brain. =all body and no mind.= at last we have begun to realize what we ought to have known all along,--that the body is not the whole man. the medical world for a long time has been in danger of forgetting or ignoring psychic suffering, while it has devoted itself to the treatment of physical disease. by way of condoning this fault it must be recognized that the five years of medical school have been all too short to learn what is needed of physiology and anatomy, histology, bacteriology, and the various other physical sciences. but at last the medical schools are realizing that they have been sending their graduates out only half-prepared--conversant with only one half of a patient, leaving them to fend for themselves in discovering the ways of the other half. many an m.d. has gone a long way in this exploration. native common sense, intuition, and careful study have enabled him to go beyond what he had learned in his text-books. but in the best universities the present-day student of medicine is now being given an insight into the ways of man as a whole--mind as well as body. the movement can hardly proceed too rapidly, and when it has had time to reach its goal, the day of the long-term sentence to nervousness will be past. in the meanwhile most physicians, lacking such knowledge and with the eye fixed largely on the body, have been pumping out the stomach, prescribing lengthy rest-cures, trying massage, diet, electricity, and surgical operations, in a vain attempt to cure a disease of the personality. physical measures have been given a good trial, but few would contend that they have succeeded. sometimes the patient has recovered--in time--but often, apparently, despite the treatment rather than because of it. sometimes, in the hands of a man like dr. s. weir mitchell, results seem good, until we realize that the same measures are ineffective when tried by other men, and that, after all, what has counted most has been the personality of the physician rather than his physical treatment. no wonder that most doctors have disliked nervous cases. to a man trained in all the exactness of the physical sciences, the apparent lawlessness and irresponsibility of the psychic side of the personality is especially repugnant. he is impatient of what he fails to comprehend. =all mind and no body.= this unsympathetic attitude, often only half conscious on the part of the regular practitioners, has led many thousands of people to follow will-o'-the-wisp cults, which pay no attention to the findings of science, but which emphasize a realization of man's spiritual nature. many of these cults, founded largely on untruth or half-falsehood, have succeeded in cases where careful science has failed. despite fearful blunders and execrable lack of discrimination in attempting to cure all the ills that flesh is heir to by methods that apply only to functional troubles, ignorant enthusiasts and quacks have sometimes cured nervous troubles where the conscientious medical man has had to acknowledge defeat. =the whole man.= but thinking people are not willing to desert science for cults that ignore the existence of these physical bodies. if they have found it unsatisfactory to be treated as if they were all body, they have also been unwilling to be treated as if they were all mind. they have been in a dilemma between two half-truths, even if they have not realized the dilemma. it has remained for modern psychotherapy to strike the balance--to treat the whole man. solidly planted on the rock of the physical sciences, with its laboratories, physiological and psychological, and with a long record of investigation and treatment of pathological cases, it resembles the mind cure of earlier days or the assertions of christian science about as much as modern medicine resembles the old bloodletting, leeching practices of our forefathers. for the last quarter-century there have been scattered groups of physicians,--brilliant, patient pioneers,--who, recognizing man as spirit inhabiting body, have explored the realm of man's mind and charted its paths. these pioneers, beginning with charcot, have been men of acknowledged scientific training and spirit, whose word must be respected and whose success in treating functional troubles stands out in sharp contrast to the fumblings of the average practitioner in this field. the results of their work have been positive, not negative. they have not merely asserted that nervous disorders are not physical; they have discovered what the trouble is and have found it to be discoverable and removable in almost every case, provided only that the right method is used. =ourselves and our bodies.= if the statement that "nervous troubles are neither physical nor imaginary but a disease of the personality," sounds rather mystifying to the average person, it is only because the average person is not very conversant with his own inner life. we shall hope, later on, to find some definite guide-posts and landmarks which will help us feel more at home in this fascinating realm. at present, we are not attempting anything more than a suggestion of the itinerary which we shall follow. a book on physical hygiene can presuppose at least a rudimentary knowledge of heart and lungs and circulation, but a book on mental hygiene must begin at the beginning, and even before the beginning must clear away misconceptions and make clear certain fundamental principles. but the gist of the whole matter is this: in a neurosis, certain forces of the personality--instincts and their accompanying emotions--which ought to work harmoniously, having become tangled up with some erroneous ideas, have lost their power of coã¶peration and are working at cross purposes, leaving the individual mis-adapted to his environment, the prey of all sorts of mental and physical disturbances. the fact that the cause is mental while the result is often physical, should cause no surprise. in the physiological realm we are used to the idea that cause and effect are often widely separated. a headache may be caused by faulty eyes, or it may result from trouble in the intestines. in the same way, we should not be too much surprised if the cause of nervous troubles is found to be even more remote, provided there is some connecting link between cause and effect. the difficulty in this case is the apparent gulf between the realm of the spirit and the realm of the body. it is hard to see how an intangible thing like a thought can produce a pain in the arm or nausea in the stomach. philosophers are still arguing concerning the nature of the relation between mind and body, but no one denies that the closest relation does exist. every year science is learning that ideas count and that they count physically, as well as spiritually. =such stuff as "nerves" are made of.= dr. tom a. williams in the little composite volume "psychotherapeutics" says that the neuroses are based not on inherently weak nervous constitutions but on ignorance and on false ideas. what, then, are some of these erroneous ideas, these misconceptions, that cause so much trouble? we shall want to examine them more carefully in later chapters, but we might glance now at a few examples of these popular bugaboos that need to be slain by the sword of cold, hard fact. =popular misconceptions about the body.= 1 "eight hours' sleep is essential to health. all insomnia is dangerous and is incompatible with health. nervous insomnia leads to shattered nerves and ultimately to insanity." 2 "overwork leads to nervous breakdown. fatigue accumulates from day to day and necessitates a long rest for recuperation." 3 "a carefully planned diet is essential to health, especially for the nervous person. a variety of food, eaten at the same time, is harmful. acid and milk--for example, oranges and milk--are difficult to digest. sour stomach is a sign of indigestion." 4 "modern life is so strenuous that our nerves cannot stand the strain." 5 "brain work is very fatiguing. it causes brain-fag and exhaustion." 6 "constipation is at the root of most physical ailments and is caused by eating the wrong kind of food." some of these misconceptions are household words and are so all but universally believed that the thought that they can be challenged is enough to bewilder one. however, it is ideas like this that furnish the material out of which many a nervous trouble is made. based on a half-knowledge of the human body, on logical conclusions from faulty premises, on hastily swallowed notions passed on from one person to another, they tend by the very power of an idea to work themselves out to fulfilment. the power behind ideas =ideas count.= ideas are not the lifeless things they may appear. they are not merely intellectual property that can be locked up and ignored at will, nor are they playthings that can be taken up or discarded according to the caprice of the moment. ideas work themselves into the very fiber of our being. they are part of us and they _do_ things. if they are true, in line with things as they are, they do things that are for our good, but if they are false, we often discover that they have an altogether unsuspected power for harm and are capable of astonishing results, results which have no apparent relation to the ideas responsible for them and which are, therefore, laid to physical causes. thinking straight, then, becomes a hygienic as well as a moral duty. =ideas and emotions.= ideas do not depend upon themselves for their driving-power. life is not a cold intellectual process; it is a vivid experience, vibrant with feeling and emotion. it therefore happens that the experiences of life tend to bring ideas and emotions together and when an idea and an emotion get linked up together, they tend to stay together, especially if the emotion be intense or the experience is often repeated. the word emotion means outgoing motion, discharging force. this force is like live steam. an emotion is the driving part of an instinct. it is the dynamic force, the electric current which supplies the power for every thought and every action of a human life. man is not a passive creature. the words that describe him are not passive words. indeed, it is almost impossible to think about man at all except in terms of desire, impulse, purpose, action, energy. there are three things that may be done with energy: first, it may be frittered away, allowed to leak, to escape. secondly, it may be locked up; this results usually in an explosion, a finding of destructive outlets. finally, it may be harnessed, controlled, used in beneficent ways. health and happiness depend upon which one of the three courses is taken. character and health evidently, it is highly important to have a working knowledge of these emotions and instincts; important to know enough about them and their purpose to handle them rightly if they do not spontaneously work together for our best character and health. the problems of character and the problems of health so overlap that it is impossible to write a book about nervous disorders which does not at the same time deal with the principles of character-formation. the laws and mechanisms which govern the everyday life of the normal person are the same laws and mechanisms which make the nervous person ill. as boris sidis puts it, "the pathological is the normal out of place." the person who is master of himself, working together as a harmonious whole, is stronger in every way than the person whose forces are divided. given a little self-knowledge, the nervous invalid often becomes one of the most successful members of society,--to use the word successful in the best sense. =it pays to know.= to be educated is to have the right idea and the right emotion in the right place. to be sure, some people have so well learned the secret of poise that they do not have to study the why nor the how. intuition often far outruns knowledge. it would be foolish indeed to suggest that only the person versed in psychological lore is skilled in the art of living. psychology is not life; it can make no claim to furnish the motive nor the power for successful living, for it is not faith, nor hope, nor love; but it tries to point the way and to help us fulfil conditions. there is no more reason why the average man should be unaware of the instincts or the subconscious mind, than that he should be ignorant of germs or of the need of fresh air. if it be argued that character and health are both inherently by-products of self-forgetful service, rather than of painstaking thought, we answer that this is true, but that there can be no self-forgetting when things have gone too far wrong. at such times it pays to look in, if we can do it intelligently, in order that we may the sooner get our eyes off ourselves and look out. the pursuit of self-knowledge is not a pleasurable pastime but simply a valuable means to an end. knowing our machine =counting on ourselves.= knowing our machine makes us better able to handle it. for, after all, each of us is, in many ways, very like a piece of marvelous and complicated machinery. for one thing, our minds, as well as our bodies, are subject to uniform laws upon which we can depend. we are not creatures of chaos; under certain conditions we can count on ourselves. freedom does not mean freedom from the reign of law. it means that, to a certain extent, we can make use of the laws. psychic laws are as susceptible to investigation, verification, and use as are any laws in the physical world. each person is so much the center of his own life that it is very easy for him to fall into the way of thinking that he is different from all the rest of the world. it is a healthful experience for him to realize that every person he meets is made on the same principles, impelled by the same forces, and fighting much the same fight. since the laws of the mental world are uniform, we can count on them as aids toward understanding other people and understanding ourselves. ="intelligent scrutiny versus morbid introspection."= it helps wonderfully to be able to look at ourselves in an objective, impersonal way. we are likely to be overcome by emotion, or swept by vague longings which seem to have no meaning and which, just because they are bound up so closely with our own ego, are not looked at but are merely felt. unknown forces are within us, pulling us this way and that, until sometimes we who should be masters are helpless slaves. one great help toward mastery and one long step toward serenity is a working-knowledge of the causes and an impersonal interest in the phenomena going on within. introspection is a morbid, emotional fixation on self, until it takes on this quality of objectivity. what cabot calls the "sin of impersonality" is a grievous sin when directed toward another person, but most of us could stand a good deal of ingrowing impersonality without any harm. the fact that the human machine can run itself without a hitch in the majority of cases is witness to its inherent tendency toward health. people were living and living well through all the centuries before the science of psychology was formulated. but not with all people do things run so smoothly. there were demoniacs in bible times and neurotics in the middle ages, as there are nervous invalids and half-well people to-day. psychology has a real contribution to make, and in recent years its lessons have been put into language which the average man can understand. psychology is not merely interested in abstract terms with long names. it is no longer absorbed merely in states of consciousness taken separately and analyzed abstractly. the newer functional psychology is increasingly interested in the study of real persons, their purposes and interests, what they feel and value, and how they may learn to realize their highest aspirations. it is about ordinary people, as they think and act, in the kitchen, on the street cars, at the bargain-counter, people in crowds and alone, mothers and their babies, little children at play, young girls with their lovers, and all the rest of human life. it is the science of _you_, and as such it can hardly help being interesting. while psychology deals with such topics as the subconscious mind, the instincts, the laws of habit, and association of ideas and suggestion, it is after all not so much an academic as a practical question. these forces govern the thought you are thinking at this moment, the way you will feel a half-hour from now, the mood you will be in to-morrow, the friends you will make and the profession you will choose, besides having a large share in the health or ill-health of your body in the meantime. summary perhaps it would be well before going farther to summarize what we have been saying. here in a nutshell is the kernel of the subject: disease may be caused by physical or by psychic forces. a "nervous" disorder is not a physical but a psychic disease. it is caused not by lack of energy but by misdirected energy; not by overwork or nerve-depletion, but by misconception, emotional conflict, repressed instincts, and buried memories. seventy-five per cent. of all cases of ill-health are due to psychic causes, to disjointed thinking rather than to a disjointed spine. wherefore, let us learn to think right. in outline form, the trouble in a neurosis may be stated something like this: lack of adaptation to the social environment--caused by lack of harmony within the personality--caused by misdirected energy--caused by inappropriate emotions--caused by wrong ideas or ignorance. working backward, the cure naturally would be: right ideas--resulting in appropriate emotions--resulting in redirected energy--resulting in harmony--resulting in readjustment to the environment. if the reader is beginning to feel somewhat bewildered by these general statements, let him take heart. so far we have tried merely to suggest the outline of the whole problem, but we shall in the future be more specific. nervous troubles, which seem so simple, are really involved with the whole mechanism of mental life and can in no way be understood except as these mechanisms are understood. we have hinted at some of the causes of "nerves," but we cannot give a real explanation until we explain the forces behind them. these forces may at first seem a bit abstract, or a bit remote from the main theme, but each is essential to the story of nerves and to the understanding of the more practical chapters in part iii. as in a bernard shaw play, the preface may be the most important part of this "drama of nerves." nor is the figure too far-fetched, because, strange as it may seem, every neurosis is in essence a drama. it has its conflict, its villain, and its victim, its love-story, its practical joke, its climax, and its denouement. sometimes the play goes on forever with no solution, but sometimes psychotherapy steps in as the fairy god-mother, to release the victim, outwit the villain, and bring about the live-happily-ever-after ending. part ii: "how the wheels go round" chapter iii _in which we find a goodly inheritance_ the story of the instincts each in his own tongue a fire mist and a planet, a crystal and a cell, a jelly-fish and a saurian, and caves where cavemen dwell; then a sense of law and beauty, and a face turned from the clod; some call it evolution and others call it god.[4] if we begin at the beginning, we have to go back a long way to get our start, for the roots of our family tree reach back over millions of years. "in the beginning--god." these first words of the book of genesis must be, in spirit at least, the first words of any discussion of life. we know now, however, that when god made man, he did not complete his masterpiece at one sitting, but instead devised a plan by which the onward urge within and the environment without should act and interact until from countless adaptations a human being was made. [footnote 4: william herbert carruth.] as the late dr. putnam of harvard university says, "we stand as the representative of a creative energy that expressed itself first in far simpler forms of life and finally in the form of human instincts."[5] and again: "the choices and decisions of the organisms whose lives prepared the way through eons of time for ours, present themselves to us as instincts."[6] [footnote 5: putnam: _human motives_, p. 32.] [footnote 6: putnam: _human motives_, p. 18.] introducing the instincts =back of our dispositions.= what is it that makes the baby jump at a noise? what energizes a man when you tell him he is a liar? what makes a young girl blush when you look at her, or a youth begin to take pains with his necktie? what makes men go to war or build tunnels or found hospitals or make love or save for a home? what makes a woman slave for her children, or give her life for them if need be? "instinct" you say, and rightly. back of every one of these well-known human tendencies is a specific instinct or group of instincts. the story of the life of man and the story of the mind of man must begin with the instincts. indeed, any intelligent approach to human life, whether it be that of the mother, the teacher, the preacher, the social worker or the neurologist, leads back inevitably to the instincts as the starting-point of understanding. but what is instinct? we are apt to be a bit hazy on that point, as we are on any fundamental thing with which we intimately live. we reckon on these instinctive tendencies every hour of the day, but as we are not used to labeling them, it may help in the very beginning of our discussion to have a list before our eyes. here, then, is a list of the fundamental tendencies of the human race and the emotions which drive them to fulfilment. the specific instincts and their emotions (after mcdougall) _instinct_ _emotion_ nutritive instinct hunger flight fear repulsion disgust curiosity wonder self-assertion positive self-feeling (elation) self-abasement negative self-feeling (subjection) gregariousness emotion unnamed acquisition love of possession construction emotion unnamed pugnacity anger reproductive instinct emotion unnamed parental instinct tender emotion these are the fundamental tendencies or dispositions with which every human being is endowed as he comes into the world. differing in degree in different individuals, they unite in varying proportions to form various kinds of dispositions, but are in greater or less degree the common property of us all. there flows through the life of every creature a steady stream of energy. scientists have not been able to decide on a descriptive term for this all-important life-force. it has been variously called "libido," "vital impulse" or "ã©lan vital," "the spirit of life," "hormã©," and "creative energy." the chief business of this life-force seems to be the preservation and development of the individual and the preservation and development of the race. in the service of these two needs have grown up these habit-reactions which we call instincts. the first ten of our list belong under the heading of self-preservation and the last two under that of race-preservation. as hunger is the most urgent representative of the self-preservative group, and as reproduction and parental care make up the race-preservative group, some scientists refer all impulses to the two great instincts of nutrition and sex, using these words in the widest sense. however, it will be useful for our purpose to follow mcdougall's classification and to examine individually the various tendencies of the two groups. =in debt to our ancestors.= an instinct is the result of the experience of the race, laid in brain and nerve-cells ready for use. it is a gift from our ancestors, an inheritance from the education of the age-long line of beings who have gone before. in the struggle for existence, it has been necessary for the members of the race to feed themselves, to run away from danger, to fight, to herd together, to reproduce themselves, to care for their young, and to do various other things which make for the well-being or preservation of the race. the individuals that did these things at the right time survived and passed on to their offspring an inherited tendency to this kind of reaction. mcdougall defines an instinct as "an inherited or innate psycho-physical disposition which determines its possessor to perceive or pay attention to objects of a certain class, to experience an emotional excitement of a particular quality upon perceiving such an object, and to act in regard to it in a particular manner, or at least to experience an impulse to such action." this is just what an instinct is,--an inherited disposition to notice, to feel, and to want to act in certain ways in certain situations. it is the something which makes us act when we cannot explain why, the something that goes deeper than reason, and that links us to all other human beings,--those who live to-day and those who have gone before. it is true that east is east and west is west, but the two do meet in the common foundation of our human nature. the likeness between men and between races is far greater and far more fundamental than the differences can ever be. =firing up the engine.= purpose is writ large across the face of an instinct, and that purpose is always toward action. whenever a situation arises which demands instantaneous action, the instinct is the means of securing it. planted within the creature is a tendency which makes it perceive and feel and act in the appropriate way. it will be noticed that there are three distinct parts to the process, corresponding to intellect, emotion, will. the initial intellectual part makes us sensitive to certain situations, makes us recognize an object as meaningful and significant, and waves the flag for the emotion; the emotion fires up the engine, pulls the levers all over the body that release its energy and get it ready for action, and pushes the button that calls into the mind an intense, almost irresistible desire or impulse to act. once aroused, the emotion and the impulse are not to be changed. in man or beast, in savage or savant, the intense feeling, the marked bodily changes, and the yearning for action are identical and unchangeable. the brakes can be put on and the action suppressed, but in that case the end of the whole process is defeated. could anything be plainer than that an instinct and its emotion were never intended to be aroused except in situations in which their characteristic action is to be desired? an emotion is the hot part of an instinct and exists solely for securing action. if all signs of the emotion are to be suppressed, all expression denied, why the emotion? but although the emotion and the impulse, once aroused, are beyond control, there is yet one part of the instinct that is meant to be controlled. the initial or receptive portion, that which notices a situation, recognizes it as significant, and sends in the signal for action, can be trained to discrimination. this is where reason comes in. if the situation calls for flight, fear is in order; if it calls for fight, anger is in order; if it calls for examination, wonder is in order; but if it calls for none of these things, reason should show some discrimination and refuse to call up the emotion. =the right of way.= there is a law that comes to the aid of reason in this dilemma and that is the "law of the common path."[7] by this is meant that man is capable of but one intense emotion at a time. no one can imagine himself strenuously making love while he is shaken by an agony of fear, or ravenously eating while he is in a passion of rage. the stronger emotion gets the right of way, obtains control of mental and bodily machinery, and leaves no room for opposite states. if the two emotions are not antagonistic, they may blend together to form a compound emotion, but if in the nature of the case such a blending is impossible, the weaker is for the time being forgotten in the intensity of the stronger. "the expulsive power of a new affection" is not merely a happy phrase; it is a fact in every day life. the problem, then, resolves itself into ways of making the desirable emotion the stronger, of learning how to form the habit of giving it the head start and the right of way. in our chapter on "choosing the emotions," we shall find that much depends on building up the right kind of sentiments, or the permanent organization of instincts around ideas. however, we must first look more closely at the separate instincts to acquaint ourselves with the purpose and the ways of each, and to discover the nature of the forces with which we have to deal. [footnote 7: sherrington: _integrative action of the nervous system_.] i the self-preservative instincts =hunger.= hunger is the most pressing desire of the egoistic or self-preserving impulse. the yearning for food and the impulse to seek and eat it are aroused organically within the body and are behind much of the activity of every type of life. as the impulse is so familiar, and its promptings are so little subject to psychic control, it seems unnecessary to do more than mention its importance. =flight and fear.= all through the ages the race has been subject to injury. species has been pitted against species, individual against individual. he who could fight hardest or run fastest has survived and passed his abilities on to his offspring. not all could be strongest for fight, and many species have owed their existence to their ability to run and to know when to run. thus it is that one of the strongest and most universal tendencies is the instinct for flight, and its emotion, fear. "fear is the representation of injury and is born of the innumerable injuries which have been inflicted in the course of evolution."[8] some babies are frightened if they are held too loosely, even though they have never known a fall. some persons have an instinctive fear of cats, a left-over from the time when the race needed to flee from the tiger and others of the cat family. almost every one, no matter in what state of culture, fears the unknown because the race before him has had to be afraid of that which was not familiar. [footnote 8: crile: _origin and nature of the emotions_.] the emotion of fear is well known, but its purpose is not so often recognized. an emotion brings about internal changes, visceral changes they are called, which enable the organism to act on the emotion,--to accomplish its object. there is only so much energy available at a given moment, stored up in the brain cells, ready for use. in such an emergency as flight every ounce of energy is needed. the large muscles used in running must have a great supply of extra energy. the heart and lungs must be speeded up in order to provide oxygen and take care of extra waste products. the special senses of sight and hearing must be sensitized. digestion and intestinal peristalsis must be stopped in order to save energy. no person could by conscious thought accomplish all these things. how, then, are they brought about? =internal laboratories.= in the wonderful internal laboratory of the body there are little glands whose business it is to secrete chemicals for just these emergencies. when an object is sighted which arouses fear, the brain cells flash instantaneous messages over the body, among others to the supra-renal glands or adrenals, just over the kidneys, and to the thyroid gland in the neck. instantly these glands pour forth adrenalin and thyroid secretion into the blood, and the body responds. blood pressure rises; brain cells speed up; the liver pours forth glycogen, its ready-to-burn fuel; sweat-glands send forth cold perspiration in order to regulate temperature; blood is pumped out from stomach and intestines to the external muscles. as we have seen, the body as a whole can respond to just one stimulus at a time. the response to this stimulus has the right of way. the whole body is integrated, set for this one thing. when fear holds the switchboard no other messages are allowed on the line, and the creature is ready for flight. but after flight comes concealment with the opposite bodily need, the need for absolute silence. this is why we sometimes get the opposite result. the heart seems to stop beating, the breath ceases, the limbs refuse to move, all because our ancestors needed to hide after they had run, and because we are in a very real way a part of them. =old-fashioned fear.= there is one passage from dr. crile's book which so admirably sums up these points that it seems worth while to insert it at length. we fear not in our hearts alone, not in our brains alone, not in our viscera alone--fear influences every organ and tissue. each organ or tissue is stimulated or inhibited according to its use or hindrance in the physical struggle for existence. by thus concentrating all or most of the nerve force on the nerve-muscular mechanism for defense, a greater physical power is developed. hence it is that under the stimulus of fear animals are able to perform preternatural feats of strength. for the same reason, the exhaustion following fear will be increased as the powerful stimulus of fear drains the cup of nervous energy even though no visible action may result.... perhaps the most striking difference between man and animals lies in the greater control which man has gained over his primitive instinctive reactions. as compared with the entire duration of organic evolution, man came down from his arboreal abode and assumed his new rã´le of increased domination over the physical world but a moment ago. and now, though sitting at his desk in command of the complicated machinery of civilization, when he fears a business catastrophe his fear is manifested in the terms of his ancestral physical battle in the struggle for existence. he cannot fear intellectually, he cannot fear dispassionately, he fears with all his organs, and the same organs are stimulated and inhibited as if, instead of its being a battle of credit, or position, or of honor, it were a physical battle with teeth and claws.... nature has but one means of response to fear, and whatever its cause the phenomena are always the same--always physical.[9] [footnote 9: crile: _origin and nature of the emotions_, p. 60 ff.] * * * * * the moral is as plain as day: learn to call up fear only when speedy legs are needed, not a cool head or a comfortable digestion. fear is a costly proceeding, an emergency measure like a fire-alarm, to be used only when the occasion is urgent enough to demand it. how often it is misused and how large a part it plays in nervous symptoms, both mental and physical, will appear more clearly in later chapters. =repulsion and disgust.= akin to the instinct of flight is that of repulsion, which impels us, instead of fleeing, to thrust the object away. it leads us to reject from the mouth noxious and disgusting objects and to shrink from slimy, creepy creatures, and has of course been highly useful in protecting the race from poisons and snakes. it still operates in the tendency to put away from us those things, mental or physical, toward which we feel aversion or disgust. recent psychological discoveries have revealed how largely a neurosis consists in putting away from us--out of consciousness,--whatever we do not wish to recognize, and so it happens that disgust plays an unexpected part in nervous disorders. =curiosity and wonder.= fortunately for the race, it has not had to wait until different features of the environment prove to be helpful or harmful. there is an instinct which urges forward to exploration and discovery and which enables the creature not only to adapt itself to the environment but to learn how to adapt the environment to itself. this is the instinct of curiosity. it is the impulse back of all advance in science, religion, and intellectual achievement of every kind, and is sometimes called "intellectual feeling." =self-assertion.= it goes almost without saying that one of the strongest and most important impulses of mankind is the instinct of self-assertion; it often gets us into trouble, but it is also behind every effort toward developed character. at its lowest level self-assertion manifests itself in the strutting of the peacock, the prancing of the horse, and the "see how big i am," of the small boy. at its highest level, when combined with self-consciousness and the moral sentiments acquired from society and developed into the self-regarding sentiment, it is responsible for most of our ideas of right, our conception of what is and what is not compatible with our self-respect. =self-abasement.= self-assertion is aroused primarily by the presence of others and especially of those to whom we feel in any way superior, but when the presence of others makes us feel small, when we want to hide or keep in the background, we are being moved by the opposite instinct of self-abasement and negative self-feeling. it may be either the real or the fancied superiority of the spectators that arouses this feeling,--their wisdom or strength, beauty or good clothes. sometimes, as in stage-fright, it is their numerical superiority. bashfulness is the struggle between the two self-instincts, assertion and abasement. our impulse for self-display urges us on to make a good impression, while our feeling of inferiority impels us to get away unnoticed. hence the struggle and the painful emotion. =gregariousness.= man has been called a gregarious animal. that is, like the animals, he likes to run with his kind, and feels a pronounced aversion to prolonged isolation. it is this "herd-instinct," too, which makes man so extremely sensitive to the opinions of the society in which he lives. because of this impulse to go with the crowd, ideas received through education are accepted as imperative and are backed up by all the force of the instinct of self-regard. when the teachings of society happen to run counter to the laws of our being, the possibilities of conflict are indeed great.[10] [footnote 10: for a thorough discussion of the importance of this instinct, see trotter's _instincts of the herd in peace and war_.] =acquisition.= another fundamental disposition in both animals and men is the instinct for possession, the instinct whose function it is to provide for future needs. squirrels and birds lay up nuts for the winter; the dog hides his bone where only he can find it. children love to have things for their "very own," and almost invariably go through the hoarding stage in which stamps or samples or bits of string are hoarded for the sake of possession, quite apart from their usefulness or value. much of the training of children consists in learning what is "mine" and what is "thine," and respect for the property of others can develop only out of a sense of one's own property rights. =construction.= there is an innate satisfaction in making something,--from a doll-dress to a poem,--and this satisfaction rests on the impulse to construct, to fashion something with our own hands or our own brain. the emotion accompanying this instinct is too indefinite to have a name but it is nevertheless a real one and plays a large part in the sense of power which results from the satisfaction of good work well done. later it will be seen how closely related is this impulse to the creative instinct of reproduction and how useful it can be in drawing off the surplus energy of that much denied instinct. =pugnacity and anger.= what is it that makes us angry? a little thought will convince us that the thing which arouses our fury is not the sight of any special object, but the blocking of any one of the other instincts. watch any animal at bay when its chance for flight has gone. the timidest one will turn and fight with every sign of fury. watch a mother when her young are threatened,--bear, or cat or lion or human. fear has no place then. it is entirely displaced by anger over the balking of the maternal instinct of protection. strictly speaking, pugnacity belongs among the instincts neither of self-preservation nor of race-preservation, but is a special device for reinforcing both groups. as fear supplies the energy for running, so anger fits us for fight,--and for nothing but fight. the mechanism is almost identical with that of fear. brain and liver, adrenals and thyroid are the means, but the emotion presses the button and releases the energy, stopping all digestion and energizing all combat-muscles. the blood is flooded with fuel and with substances which, if not used, are harmful to the body. we were never meant to be angry without fighting. the habit of self-control has its distinct advantages, but it is hard on the body, which was patterned before self-control came into fashion. the wise man, once he is aroused, lets off steam at the woodpile or on a long, vigorous walk. he probably does not say to himself that he is a motor animal integrated for fight and that he must get rid of glycogen and adrenalin and thyroid secretion. he only knows that he feels better "on the move." the wiser man does not let himself get angry in the first place unless the situation calls for fight. however, the fight need not be a hand-to-hand combat with one's fellow man. william james has pointed out that there is a "moral equivalent for war," and that the energy of this instinct may be used to reinforce other impulses and help overcome obstacles of all sorts. a good deal of the business man's zest, the engineer's determination, and the reformer's zeal spring from the fight-instinct used in the right way. as james, cannon, and others have pointed out, the way to end war may be to employ man's instinct of pugnacity in fighting the universal enemies of the race--fire, flood, famine, disease, and the various social evils--rather than let it spend its force in war between nations. even our sports may be offshoots of the fight-instinct, for mcdougall holds that the play-tendency has its root in the instinct of rivalry, a modified form of pugnacity. evidently fighting-blood is a useful inheritance, even to-day, and rightly directed is a necessary part of a complete and forceful personality. this, then, completes the list of self-preservative instincts, those which are commonly called egoistic and which have been given us for the maintenance of our own individual personal lives. but our endowment includes another set of impulses which are no less important and which must be reckoned with if human conduct is to be understood. chapter iv _in which we learn more about ourselves_ the story of the instincts (continued) ii. the race-preservative instincts =looking beyond ourselves.= we sometimes speak of self-preservation as though it were the only law of life, while as a matter of fact it is but half the story. nature has seen to it that there shall be planted in every living creature an innate urge toward the larger life of the race. although the creature may never give a conscious thought to the welfare of the race, he still bears within himself a set of instincts which have as their end and aim, not the individual at all, but society as a whole, and the life of generations that are to come. he is bigger than he knows. although he may have no notion why he feels and acts as he does, and although he may pervert the purpose for his own selfish end, he is continually being moved by the mighty impulse of the race-life, an impulse which often outrivals the desire i or his own personal existence. the craving to reproduce ourselves and the craving to cherish and protect our young are among the most dynamic forces in life. the two desires are so closely bound together that they are often spoken of as one under the name of the sex-instinct, or the family instincts. let us look first at that part of the yearning which urges toward perpetuating our own life in offspring. =watching nature work.= it is wonderful, indeed, to watch nature in the long process of evolution, as she adapts her methods to the growing complexity of the organism. with a variety and ingenuity of means, but always with the same steady purpose, she works from the lowest levels,--where there is no true reproduction, only multiplication by division,--on through the beginning of reproduction proper, where a single parent produces the offspring; then on to the level where it takes two parents of different structure to produce a new organism, and sex-life begins. at first nature does not even demand that father and mother shall come near each other. in the water, the female of this type lays an egg, and the male, guided by his instinct, swims to it and deposits his fertilizing fluid. in plant life, bird and bee, attracted by wonderfully planned perfumes and color and honey, are called in to carry the pollen from male to female cell. but it is when we come to the highest level that we find even more subtle ways planned to accomplish the desired end. here we enter the realm of individual initiative, for it is not now enough to leave to external forces the joining of the two life-elements. in order to make a new individual, father and mother must be drawn together, and so there enters into the situation a personal relationship with all that that implies. because nature has had to provide ways of drawing individuals to one another, she has put into the higher types of life the power of mutual attraction,--a power which in man, the highest of all types, is responsible for many outgrowths that seem far removed from the original purpose. =the love-motif.= on the one hand, there is the persistent desire to be attractive, which manifests itself in the subtlest ways. how many of the yearnings and activities of human life have their roots in this ancient and honorable desire! the love of pretty clothes,--however it may seem to be motivated and however it may be complicated by other motives,-draws its energy, fundamentally, from the same need that provides the gay plumage and limpid song of the bird or the painted wings of the butterfly. on the other hand, there is the capability of being attracted, with all the personal relationships which spring from the power of admiring and loving another person. the interest in others does not expend its whole force on its primary objects,--mate and children. it flows out into all human relationships, developing all the possibilities of loving which mean so much in human life; the love of man for man and woman for woman, as well as mutual love of man and woman. a force like this, once planted, especially in the higher types of life, does not spend all its energies in its main trunk. it sends out branches in many directions, bearing by-products which are rich in value for all of life. many of our richest relationships, our best impulses, and our most firmly fixed social habits spring from the family instincts of reproduction and parental care. the social life of our young people, so well calculated to bring young men and women together; all the beauty of family life and, as we shall later see, all the broader benevolent activities for society in general, are energized by the same love-instincts which form so large a part of human nature. learning to love =a four-grade school.= it is impossible to watch the growth of the love-life of a human being, to trace its development from babyhood up to its culmination in mating and parenthood, without a sense of wonder at the steady purpose behind it all. we used to believe that the love for the young girl that suddenly blooms forth in the callow youth was an entirely new affair, something suddenly planted in him as he developed into manhood; but now we know, thanks to the uncovering of human nature by the painstaking investigations of the psycho-analytic school of psychologists, that the seeds of the love-life are planted, not in puberty, but with the beginning of life itself. looked at in one way, all infancy and childhood are a preparation, a training of the love-instinct which is to be ready at the proper time to find its mate and play its part in the perpetuation of the race. nature begins early. as she plants in the tiny baby all the organs that shall be needed during its lifetime, so she plants the rudiments of all the impulses and tendencies that shall later be developed into the full-grown instincts. there have been found to be four periods in the love-life of the growing child, three of them preparatory steps leading up to maturity; periods in which the main current of love is directed respectively toward self, parents, comrades, and finally toward lover or mate. =like narcissus.= in the first stage, the baby's interest is in his own body. he is getting acquainted with himself, and he soon finds that his body contains possibilities of pleasurable sensations which may be repeated by the proper stimulation. besides the hunger-satisfaction that it brings, the act of sucking is pleasurable in itself, and so the baby begins to suck his thumb or his quilts or his rattle. later, this impulse to stimulate the nerves about the mouth finds its satisfaction in kissing, and still later it plays a definite part in the wooing process; but at first the child is self-sufficient and finds his pleasure entirely within himself. other regions of the body yield similar pleasure. we often find a tiny child rubbing his genital organs or his thighs or taking exaggerated pleasure in riding on someone's foot in order to stimulate these nerves, which he has discovered at first merely by chance. when he begins to run around, he loves to exhibit his own body, to go about naked. none of this is naughtiness or perversion; it is only nature's preparation of trends that she will later need to use. the child is normally and naturally in love with himself.[11] but he must not linger too long in this stage. none of the channels which his life-force is cutting must be dug too deep, else in later life they will offer lines of least resistance which may, on occasion, invite illness or perversion. [footnote 11: this is the stage which is technically known as auto-eroticism or self-love.] =in love with his family.= presently nature pries the child loose from love of himself and directs part of his interests to people outside himself. before he is a year old, part of his love is turned to others. in this stage it is natural that at first his affection should center on those who make up his home circle,--his parents and other members of the household. even in this early choice we see a foreshadowing of his future need. the normal little boy is especially fond of his mother, and the normal little girl of her father. not all the love goes to the parent of the opposite sex, but if the child be normal, a noticeably larger part finds its way in that direction. observing parents can often see unmistakable signs of jealousy: toward the parent of the same sex, or the brother or sister of the same sex. the little boy who sleeps with his mother while his father is away, or who on these occasions gets all the attention and all the petting he craves, is naturally eager to perpetuate this state of affairs. many a small boy has been heard to say that he wished his father would go away and stay all the time,--to the horror of the parents who do not understand. all this is natural enough, but it is not to be encouraged. the pattern of the father or the mother must not be stamped too deep in the impressionable child-mind. too little love and sympathy are bad, leading to repression and a morbid turning in of the love-force; but too much petting, too many caresses are just as bad. sentimental self-indulgence on the part of the parents has been repeatedly proved to be the cause of many a later illness for the child. as the right kind of family love and comradeship, the kind that leads to freedom and self-dependence, is among the highest forces in life, so the wrong kind is among the worst. parents and their substitutes--nurses, sisters, and brothers--are but temporary stopping-places for the growing love, stepping-stones to later attachments which are biologically more necessary. the small boy who lets himself be coddled and petted too long by his adoring relatives, who does not shake off their caresses and run away to the other boys, is doomed to failure, and, as we shall later see, probably to illness.[12] [footnote 12: one of the best discussions of this theme is found in the chapter "the only or favorite child," by a.a. brill, in _psychoanalysis_.] in the later infantile period, the child, besides wanting to exhibit his own body, shows marked interest in looking at the bodies of others, and marked curiosity on sex-questions in general. he particularly wants to know "where babies come from." if his questions are unfortunately met by embarrassment or laughing evasion, or by obvious lying about the stork or the doctor or the angels, his curiosity is only whetted, and he comes to the very natural conclusion that all matters of sex are sinful, disgusting, and indecent, and to be investigated only on the sly. this conception cannot be brought into harmony with the unconscious mental processes arising from his race-instincts nor with his instinctive sense that "whatever is is right." the resulting conflict in some four-year-old children is surprisingly intense. astonished indeed would many parents be if they knew what was going on inside the heads of their "innocent" little children; not "bad" things, but pathetic things which a little candor would have avoided. alongside the rudimentary impulses of showing and looking, there is developed another set of trends which nature needs to use later on, the so-called sadistic and masochistic impulses, the desire to dominate and master and even to inflict pain, and its opposite impulse which takes pleasure in yielding and submitting to mastery. these traits, harking back to the time when the male needed to capture by force, are of course much more evident in adolescence and especially in love-making, but have their beginning in childhood, as many a mother of cruel children knows to her sorrow. in adolescence, when sex-differentiation is much more marked, the dominating impulse is stronger in the boy and the yielding impulse in the girl; but in little children the differentiation has not yet begun. =gang and chum.= at about four or five years the child leaves the infantile stage of development, with its self-love and its intense devotion to parents and their substitutes. he begins to be especially interested in playmates of his own sex, to care more for the opinions of the gang--or if it be a little girl, of the chum--than for those of the parents. the life-force is leading him on to the next step in his education, freeing him little by little from a too-hampering attachment to his family. this does not mean that he does not love his father and mother. it means only that some of his love is being turned toward the rest of the world, that he may be an independent, socially useful man. this period between infancy and puberty is known as the latency period. all interest in sex disappears, repressed by the spontaneously developing sense of shame and modesty and by the impact of education and social disapproval. the child forgets that he was ever curious on sex-matters and lets his curiosity turn into other, more acceptable channels. =the mating-time.= we are familiar with the changes that take place at puberty. we laugh at the girl who, throwing off her tom-boy ways, suddenly wants her skirts let down and her hair done up. we laugh at the boy who suddenly leaves off being a rowdy, and turns into a would-be dandy. we scold because this same boy and girl who have always been so "sweet and tractable" become, almost overnight, surly and cantankerous, restive under authority and impatient of family restraint. we should neither laugh nor scold, if we understood. nature is succeeding in her purpose. she has led the young life on from self to parents, from parents to gang or chum, and now she is trying to lead it away from all its earlier attachments, to set it free for its final adventure in loving. the process is painful, so painful that it sometimes fails of accomplishment. in any case, the strain is tremendous, needing all the wisdom and understanding which the family has to offer. it is no easy task for any person to free himself from the sense of dependence and protection, and the shielding love that have always been his; to weigh anchors that are holding him to the past and to start out on the voyage alone. at this time of change, the chemistry of the body plays an important part in the development of the mental traits; all half-developed tendencies are given power through the maturing of the sex-glands, which bind them into an organization ready for their ultimate purpose. the current is now turned on, and the machinery, which has been furnished from the beginning, is ready for its task. after a few false starts in the shape of "puppy love," the mature instinct, if it be successful, seeks until from among the crowd it finds its mate. it has graduated from the training-school and is ready for life. civilization's problem =when nature's plans fall through.= we have been describing the normal course of affairs. we know that all too often the normal is not achieved. inner forces or outer circumstances too often conspire to keep the young man or the young woman from the culmination toward which everything has been moving. if the life-force cannot liberate itself from the old family grooves to forge ahead into new channels, or if economic demands or other conditions make postponement necessary, then marriage is not possible. all the glandular secretions and internal stimuli have been urging on to the final consummation, developing physical and emotional life for an end that does not come; or if it does come, is not sufficient to satisfy the demands of the age-old instinct which for millions of years knew no restraint. in any case, man finds himself, and woman herself, face to face with a pressing problem, none the less pressing because it is in most cases entirely unrecognized. =blundering instincts.= the older a person is, the more fixed are his habits. now, an instinct is a race-habit and represents the crystallized reactions of a past that is old. whatever has been done over and over again, millions of times, naturally becomes fixed, automatic, tending to conserve itself in its old ways, to resist any change and to act as it has always acted. this conserves energy and works well so long as conditions remain the same. but if for any reason there comes a change, things are likely to go wrong. by just so far as things are different, an automatic habit becomes a handicap instead of a help. this having to act under changed conditions is exactly the trouble with the reproductive instinct. under civilization, conditions have changed but the instinct has not. it is trying to act as it always has acted, but civilized man wills otherwise. the change that has come is not in the physical, external environment, but in man himself and in the social environment which he has created. there is in man an onward urge toward new and better things. side by side with the desire to live as he always has lived, there is a desire to make new adaptations which are for the advancement of the whole race-life. besides the natural wish to take his desires as he finds them, there is also the wish to modify them and use them for higher and more socially useful ends. as the race has found through long experience that monogamy is to be preferred to promiscuous mating; that the highest interests of life are fostered by loyalty to the institution of the family; that the careful rearing of several children rather than the mere production of many is in the long run to be desired; and that a single standard of morality is practicable; so society has established for its members a standard which is in direct opposition to the immeasurable urge of the past. to make matters worse, there have at the same time grown up in many communities a standard of living and an economic competition which still further limit the size of the family and the satisfaction of the reproductive impulse. =the perpetual feud.= there thus arises the strategic struggle between that which the race has found good in the past and that which the race finds good in the present. as the older race-experience is laid in they body and built into the very fiber of the individual, inherited as an innate impulse, it has become an integral part of himself, an individual need rather than a social one. on the other hand, man has, as another innate part of his being, the desire to go with the herd, to conform to the standards of his fellows, to be what he has learned society wants him to be. hence the struggle, insistent, ever more pressing, between two sets of desires within the man himself; the feud between the past and the present, between the natural and the social, between the selfish and the ideal. on one side, there is the demand for instinctive satisfaction; on the other, for moral control; on one side the demand for pleasure; on the other, the demands of reality.[13] [footnote 13: "all the burdens of men or society are caused by the inadequacies in the association of primal animal emotions with those mental powers which have been so rapidly developed in man-kind."--shaler quoted by hinkle: introduction to jung's _psychology of the unconscious_.] two factors intensify the conflict. in the first place, the older habits have the head start. compared with the almost limitless extent of our past history, our desire for the control of the instincts is very new indeed. it requires the long look and the right perspective to understand how very lately we have entered into our new conditions and how old a habit we are trying to break. in the second place, the larger part of the stimulus comes from within the body itself. when studying the other instincts, we saw that the best way to control was to refuse to stimulate when the situation was not suitable for discharge. but with the organically aroused sex-instinct there is no such power of choice. we may fan the flame by the thoughts we think or the environment we seek, or we may smother the flame until it is out of sight, but we cannot extinguish it by any act of ours. the issue has always been too important to be left to the individual. the stimulation comes, primarily, not by way of the mind but by way of the body. with this instinct we cannot "stop before we begin," because nature has taken the matter out of our hands and begins for us. the bulwark we have built with the competing forces so strong and the issues so great, it is not to be wondered at that society has had to build up a massive bulwark of public opinion, to establish regulations and fix penalties that are more stringent than those imposed in any other direction. nor is it remarkable that in its effort to protect itself, society has sometimes made mistakes. these blunders seem to lie in two directions. assuming that it is nearly impossible for the male to control his instincts, and that, after all, it does not matter so much whether he does or not, society has blinked at license in men, and thus has fostered a demoralizing, anti-social double standard which has broken up countless homes, has been responsible for the spread of venereal diseases, and has been among the greatest curses of modern civilization. at the same time society, in its efforts to maintain its standards for woman, has taught its children, especially its girls, that anything savoring of the word "sexual" is sinful, disgusting, and impure. to be sure, very many women have modified their childish views, but an astonishingly large number conserve, even in maturity, their warped ideas about the whole subject of sex. many a mature woman secretly believes that she, at least, is not guilty of harboring anything so "vulgar" as a reproductive instinct, not realizing that if this were so, she would be, in very truth, a freak of nature. of course, woman is by nature as fully endowed with sex instincts as is man. kipling portrays the female of the species as "deadlier than the male" in that the very framework of her constitution outlines the one issue for which it was launched,--stanch against any attack which might endanger the carrying on of life. feeling the force of this instinctive urge, she braces herself against precipitancy in response by what seems almost a negation. just as we lean well in when riding around a corner, in order to keep ourselves from falling out, so by an "over-compensation" for what is unconsciously felt to be danger woman increases her feeling of safety by setting up a taboo on the whole subject of sex. it is time that we freed our minds from the artificial and perverted attitude toward this dominant impulse; time to rescue the word "sex" from its implications of grossness and sensuousness, and to recognize the instinct in its true light as one of the necessary and holy forces of life, a force capable of causing great damage, but also holding infinite possibilities for good if wisely directed. society only gets its members into trouble when, even by implication, it attempts to deny its natural make-up, and allows little children to grow up with the false idea that one of their strongest impulses is to be shunned by them as a thing of shame. we cannot dam back the flood by building a bulwark of untruth, and then expect the bulwark to hold. =adaptable energy.= we neither have to give in to our over-insistent desires nor to deny that they exist. man has a power of adaptation. just when we seem to run up against a dead wall, to face an irreconcilable conflict, we find a wonderful power of indirect expression that affords satisfaction to all the innate forces without doing violence to the ethical standards which have proved so necessary for the development of character. hunger, which, like the reproductive instinct, is stimulated by the changing chemistry of the body, can be satisfied only by achieving its primary purpose, the taking of material food; but the creative impulse to reproduce oneself possesses a unique ability to spiritualize itself and expend its energy in other lines of creative endeavor. there seems to be some sort of close connection between the especially intense energy of the reproductive instinct and the modes of expression of the instinct for construction; a connection which makes possible the utilization of threatening destructive energy by directing it toward socially valuable work. just as we harness the mountain stream and use its wild force to light our cities, or catch the lightning to run our trolley cars, so we find man and woman--under the right conditions--easily and naturally switching over the power of their surplus sex-energy to ends which seem at first only slightly related to its original aim, but which resemble it in that they too are self-expressive and creative. if a person is able to express himself in some real way, to give himself to socially needed work; if he can reproduce himself intellectually and spiritually in artistic production, in invention, in literature, in social betterment, he is drawing on an age-old reservoir of creative energy, and by so doing is relieving himself of inner tension which would otherwise seek less beneficent ways of expression. the world knew all this intuitively for a long time before it knew it theoretically. the novelists, who are unconsciously among the best psychologists, have thoroughly worked the vein. the average man knows it. "he was disappointed in love," we say, "and we thought he would go to pieces, but now he has found himself in his work"; or, "she will go mad if she doesn't find some one who needs her." it is only lately that science has caught up with intuition, but now the physicians and psychologists who have had the most intimate and first-hand acquaintance with the human heart are recognizing, to a man, this unique power of the love-instinct and its possibilities for creative work of every sort.[14] [footnote 14: among those who have shown this connection between the love-force and creative work are freud, jung, jelliffe, white, brill, jones, wright, frink, and the late dr. putnam of harvard university, who writes: "freud has never asserted it as his opinion and it certainly is not mine, that this is the only root from which artistic expression springs. on the other hand, it is probable that all artistic productions are partly referable to this source. a close examination of many of them would enable any one to justify the opinion that it is a source largely drawn upon."--_human motives_. p. 87.] =higher levels.= freud has called this spiritualization of natural forces by a term borrowed from chemistry. as a solid is "sublimated" when transformed into a gas, so a primal impulse is said to be "sublimated" when it is diverted from its original object and made to serve other ends. by this power of sublimation the little exhibitionist, who loved to show himself, may become an actor; the "cruel" boy who loved to dissect animals may become a surgeon; the sexually curious child may turn his curiosity to other things and become a scholar; the "born mother," if denied children of her own or having finished with their upbringing, may take to herself the children of the city, working for better laws and better care for needy little ones; the man or woman whose sex-instinct is too strong to find expression in legitimate, direct ways, may find it a valuable resource, an increment of energy for creative work, along whatever line his talent may lie. there is no more marvelous provision in all life than this power of sublimation of one form of energy into another, a provision shadowing forth almost limitless possibilities for higher adaptations and for growth in character. as we think of the distance we have already traveled and the endless possibilities of ever higher excursions of the life-force, we feel like echoing paul's words: "he who began a good work in you will perfect it unto the end." the history of the past holds great promise for the future. =when sublimation fails.= but in the meantime we cannot congratulate ourselves too heartily. sublimation too often fails. there are too many nervous wrecks by the way, too many weak indulgers of original desires, too many repressed, starved lives with no outlet for their misunderstood yearnings; and, as we shall see, too many people who, in spite of a big lifework, fail to find satisfaction because of unnecessary handicaps carried over from their childhood days. "society's great task is, therefore, the understanding of the life-force, its manifold efforts at expression and the way of attaining this, and to provide as free and expansive ways as possible for the creative energy which is to work marvelous things for the future." if "the understanding of the life force" is to be available for use, it must be the property of the average man and woman, the fathers and mothers of our children, the teachers and physicians who act as their advisers and friends.[15] this chapter is intended to do its bit toward such a general understanding. [footnote 15: "appropriate educational processes might perhaps guide this enormous impulsive energy toward the maintenance instead of the destruction of marriage and the family. but up to the present time, education with respect to this moral issue has commonly lacked any such constructive method. the social standard and the individual impulse have simply collided, and the individual has been left to resolve the conflict, for the most part by his own resources."--g.a. coe: _psychology of religion_, p. 150.] parental instinct and tender emotion =until they can fly.= only half of nature's need is met by the reproductive instinct. her carefulness in this direction would be largely wasted without that other impulse which she has planted, the impulse to protect the new lives until they are old enough to fend for themselves. the higher the type of life and the greater the future demands, the longer is the period of preparation and consequent period of parental care. this fact, coupled with man's power for lasting relationships through the organization of permanent sentiments, has made the, bond between parent and child an enduring one. needless to say, this relationship is among the most beautiful on earth, the source of an incalculable amount of joy and gain. however, as we have already suggested, there lurks here, as in every beneficent force, a danger. if parents forget what they are for, and try to foster a more than ordinary tie, they make themselves a menace to those whom they most love. any exaggeration is abnormal. if the childhood bond is over-strong, or the childhood dependence too long cultivated, then the relationship has overstepped its purpose, and, as we shall later see, has laid the foundation for a future neurosis. =mothering the world.= probably no instinct has so many ways of indirect expression as this mothering impulse of protection. aroused by the cry of a child in distress, or by the thought of the weakness, or need, or ill-treatment of any defenseless creature, this mother-father impulse is at the root of altruism, gratitude, love, pity, benevolence, and all unselfish actions. there is still a great difference of opinion as to how man's spiritual nature came into being; still discussion as to whether it developed out of crude beginnings as the rest of his physical and mental endowment has developed, or whether it was added from the outside as something entirely new. be that as it may, the fact remains that man has as an innate part of his being an altruistic tendency, an unselfish care for the welfare of others, a relationship to society as a whole,--a relationship which is the only foundation of health and happiness and which brings sure disaster if ignored. the egoistic tendencies are only a part of human nature. part of us is naturally socially minded, unselfish, spiritual, capable of responding to the call to lose our lives in order that others may find theirs. summary civilized man as he is to-day is a product of the past and can be understood only as that past is understood. the conflicts with which he is confronted are the direct outcome of the evolutional history of the race and of its attempt to adapt its primitive instincts to present-day ideals. character is what we do with our instincts. according to freud, all of a man's traits are the result of his unchanged original impulses, or of his reactions against those impulses, or of his sublimation of them. in other words, there are three things we may do with our instincts. we may follow our primal desires, we may deny their existence, or we may use them for ends which are in harmony with our lives as we want them to be. as the first course leads to degeneracy, the second to nervous illness, and the third to happy usefulness, it is obviously important to learn the way of sublimation. sometimes this is accomplished unconsciously by the life-force, but sometimes sublimation fails, and is reestablished only when the conscious mind gains an understanding of the great forces of life. this method of reeducation of the personality as a means of treatment in nervousness is called psycho-therapy. =religion's contribution.= if it be asked why, amid all this discussion of instincts and motives we have made no mention of that great energizer religion, we answer that we have by no means forgotten it, but that we have been dealing solely with those primary tendencies out of which all of the compound emotions are made. man has been described as instinctively and incurably religious, but there seems no doubt that religion is a compound reaction, made up of love,--sympathetic response to the parental love of god,--fear, negative self-feeling, and positive self-feeling in the shape of aspiration for the desired ideal of character; all woven into several compound emotions such as awe, gratitude, and reverence. it goes almost without saying that religion, if it be vital, is one of the greatest sources of moral energy and spiritual dynamic, and that it is and always has been one of the greatest aids to sublimation that man has found. a force like the christian religion, which sets the highest ideal of character and makes man want to live up to it, and which at the same time says, "you can. here is strength to help you"; which unifies life and fills it with purpose; which furnishes the highest love-object and turns the thought outward to the good of mankind--such a force could hardly fail to be a dynamic factor in the effort toward sublimation. this book, however, deals primarily with those cases for which religion has had, to call science to her aid in order to find the cause of failure, to flood the whole subject with light, and to help cut the cords which, binding us to the past, make it impossible to utilize the great resources that are at hand for all the children of men. =where we keep our instincts.= it must have been impossible to read through these two chapters on instinct without feeling that, after all, we are not very well acquainted with ourselves. the more we look into human nature, the more evident it becomes that there is much in each one of us of which we are only dimly aware. it is now time for us to look a little deeper,--to find where we keep these instinctive tendencies with which it is possible to live so intimately without even suspecting their existence. we shall find that they occupy a realm of their own, and that this realm, while quite out of sight, is yet open to exploration. chapter v _in which we look below the surface and discover a veritable wonderland_ the subconscious mind strangers to ourselves =hidden strings.= a collie dog lies on the hearthrug. a small boy with mischievous intent ties a fine thread to a bone, hides himself behind a chair, and pulls the bone slowly across the floor. the dog is thrown into a fit of terror because he does not know about the hidden string. a chinese in the early days of san francisco stands spell-bound at the sight of a cable car. "no pushee. no pullee. go allee samee like hellee!" he does not know about the hidden string. a woman of refinement and culture thinks a thought that horrifies her sensitive soul. it is entirely out of keeping with her character as she knows it. in her misunderstanding she considers it wicked and thrusts it from her, wondering how it ever could have been hers. she does not know about the hidden string. in the last two chapters we thought together about some of these strings, examining the fibers of which they are made and learning in what directions they pull. we found them to be more powerful than we should have supposed, more insistent and less visible. we found that instinctive desire is the string, the cable that energizes our every act, but that our desires are neither single nor simple, and are but rarely on the surface. many of us live with them a long time, feeling the tug, but not recognizing the string. =there's a reason.= we take our thoughts and feelings and actions for granted, without stopping very often to wonder where they come from. but there is always a reason. when the law of cause and effect reaches the doorsill of our minds, it does not stop short to give way to the law of chance. we wake up in the morning with a certain thought on top. we say it "just happens." but nothing ever just happens. no thought that ever comes into our heads has been without its history,--its ancestors and its determining causes. but what about dreams? they, at least, you say, have no connections, no past and no future, only a weird, fantastic present. strange to say, dreams have been found to be as closely related to our real selves, as interwoven with the warp and woof of our lives as are any of our waking thoughts. even dreams have a reason. we find ourselves holding certain beliefs and prejudices, interested in certain things and indifferent to others, liking some foods, some colors and disliking others. search our minds as we will, we find no clue to many of these inner trends. why? the answer is simple. the cause is hidden below the surface. if we try to explain ourselves on the basis of the open-to-inspection part of our minds, we must come to the conclusion that we are queer creatures indeed. only by assuming that there is more to us than we know, can we find any rational basis for the way we think and feel and act. =a real mind.= we learn of our internal machinery by what it does. we must infer a part of our minds which introspection does not reveal, a mind within the mind, able to work for us even while we are unaware of its existence. this inner mind is usually known as the subconscious, the mind under the level of consciousness.[16] we forget a name, but we know that it will come to us if we think about something else. presently, out of somewhere, there flashes the word we want. where was it in the meanwhile, and what hunted it out from among all our other memories and sent it up into consciousness? the something which did that must be capable of conserving memories, of recognizing the right one and of communicating it,--surely a real mind. [footnote 16: writers of the psycho-analytic school use the word "unconscious" to denote the lower layers of this region, and "fore-conscious" to denote its upper layers. morton prince uses the terms "unconscious" and "conscious" to denote the different strata. as there is still a good deal of confusion in the use of terms, it has seemed to us simpler to use throughout only the general term "subconscious."] one evening my collaborator fumbled unsuccessfully for the name of a certain well-known journalist and educator. it was on the tip of her tongue, but it simply would not come, not even the initial letter. in a whimsical mood she said to herself just as she went to sleep, "little subconscious mind, you find that name to-night." in the middle of the night she awoke, saying, "williams--talcott williams." the subconscious, which has charge of her memories, had been at work while she slept. the history of literature abounds in stories of under-the-surface work. the man of genius usually waits until the mood is on, until the muse speaks; then all his lifeless material is lighted by new radiance. he feels that some one outside himself is dictating. often he merely holds the pen while the finished work pours itself out spontaneously as if from a higher source. but it is not only the man of genius who makes use of these unseen powers. he may have readier access to his subconscious than the rest of us, but he has no monopoly. the most matter-of-fact man often says that he will "sleep over" a knotty problem. he puts it into his mind and then goes about his business, or goes to sleep while this unseen judge weighs and balances, collects related facts, looks first at one side of the question and then at the other, and finally sends up into consciousness a decision full of conviction, a decision that has been formulated so far from the focus of attention that it seems to be something altogether new, a veritable inspiration. we must infer the subconscious from what it does. things happen,--there must be a cause. some of the things that happen presuppose imagination, reason, intelligence, will, emotion, desire, all the elements of mind. we cannot see this mind, but we can see its products. to deny the subconscious is to deny the artist while looking at his picture, to disbelieve in the poet while reading his poem, and to doubt the existence of the explosive while listening to the report. the subconscious is an artist, a poet, and an explosive by turns. if we deny its existence, a good portion of man's doings are unintelligible. if we admit it, many of his actions and his afflictions which have seemed absurd stand out in a new light as purposeful efforts with a real and adequate cause. =the submerged nine tenths.= the more deeply psychologists and physicians have studied into these things, the more certainly have they been forced to the conclusion that the conscious mind of man, the part that he can explore at will, is by far the smaller part of his personality. since this is to some people a rather startling proposition, we can do no better than quote the following statement from white on the relation of consciousness to the rest of the psychic life: consciousness includes only that of which we are _aware_, while outside of this somewhat restricted area there lies a much wider area in which lie the deeper motives for conduct, and which not only operates to control conduct, but also dictates what may and what may not become conscious. stanley hall has very forcibly put the matter by using the illustration of the iceberg. only one-tenth of the iceberg is visible above water; nine-tenths is beneath the surface. it may appear in a given instance that the iceberg is being carried along by the prevailing winds and surface currents, but if we keep our eyes open we shall sooner or later see a berg going in the face of the wind, and, so, apparently putting to naught all the laws of aerodynamics. we can understand this only when we come to realize that much the greater portion of the berg is beneath the surface and that it is moving in response to invisible forces addressed against this submerged portion. consciousness only arises late in the course of evolution and only in connection with adjustments that are relatively complex. when the same or similar conditions in the environment are repeatedly presented to the organism so that it is called upon to react in a similar and almost identical way each time, there tends to be organized a mechanism of reaction which becomes more and more automatic and is accompanied by a state of mind of less and less awareness.[17] [footnote 17: white: _mechanisms of character formation_.] it is easy to see the economy of this arrangement which provides ready-made patterns of reaction for habitual situations and leaves consciousness free for new decisions. since an automatic action, traveling along well-worn brain paths, consumes little energy and causes the minimum of fatigue, the plan not only frees consciousness from a confusing number of details, but also works for the conservation of energy. while consciousness is busy lighting up the special problems of the moment, the vast mass of life's demands are taken care of by the subconscious, which constitutes the bulk of the mind. "properly speaking, the unconscious is the real psyche."[18] [footnote 18: freud: _interpretation of dreams_, p. 486.] =the heart of psychology.= in the face of all this, it is not to be wondered at that the problem of the subconscious has been called not one problem of psychology but the problem. it cannot be denied that the discoveries which have already been made as to its activities have been of immense practical importance in the understanding of normal conduct and in the treatment of the psycho-neuroses. if some of the methods--such as hypnosis, automatic writing, and interpretation of dreams--which are used to investigate its activities seem to savor of the charlatan and the mountebank, it is because they have occasionally been appropriated by the ignorant and the unscrupulous. their real setting is the psychological laboratory and the physician's office. in the hands of men like sigmund freud, boris sidis, and morton prince, they are as scientific as the apparatus of any other laboratory and their findings are as susceptible of proof. we may, then, go forward with the conviction that we are walking on solid ground and that the main paths, at least, will turn into beaten highways. ancestral memories =race-memories.= an individual as he stands at any moment is the product of his past,--the past which he has inherited and the past which he has lived. in other words, he is a bundle of memories accumulated through the experience of the race, and through his own experience as a person. some of these memories are conscious, and these he calls his, while others fail to reach consciousness and are not recognized as part of his assets. the instincts form the starting-point of mind, conscious and subconscious, and are the foundation upon which the rest is built. they often show themselves as part of our conscious lives, but their roots are laid deep in the subconscious from which they can never be eradicated. this deepest-laid instinctive layer of the subconscious is little subject to change. it represents the earlier adjustments of the race, crystallized into habit. it takes no account of the differences between the present and the past. it knows no culture, no reason, no lately acquired prudence. it is all energy and can only wish, or urge toward action. but since only those race-memories became instincts which had proved needful to the race in the long run, they are on the whole beneficent forces, working for the good of the race and the good of the individual, if he learns how to handle them aright and to adapt them to present conditions. this instinctive urge toward action arouses in the individual an organic response that is felt as a tension or craving and is mainly dependent upon its own chemical constitution at the moment. hunger is the sensation caused by the little muscular contractions in the stomach when the body is low in its food supply. sudden fright is felt as an all-gone sensation "at the pit of the stomach." what really happens is a tightening up of the circular muscles of the blood-vessels lying in the network of the solar plexus, and a spasm of the muscles of the digestive tract. the hungry stomach impels to action until satisfied; the physical discomfort in fear impels toward measures of safety. the apparatus that is made use of by the subconscious in carrying out this instinctive urge is called the autonomic nervous system.[19] it regulates all the functions of living, not only under the stress of emotion, but during every moment of waking or sleeping. [footnote 19: kempf: "the tonus of automatic segments as a cause of abnormal behavior," _journal of nervous and mental diseases_, january, 1921.] =a capable manager.= the conscious mind could not possibly send messages to the numerous glands that fit the body for action, nor attend to all the delicate adjustments that enter into the process. the conscious mind in most of us does not even know of the existence of the organs and secretions involved, but something sends the messages and it is something that has a remarkable likeness to mind as we usually think of mind,--something which takes advantage of the past and gages means to an end with a nicety that excites our wonder. =take no anxious thought.= we take food into our stomachs and forget about it, if we are wise; and this subconscious overseer who through millions of years of experience has learned how to digest food does the rest. as with digestion, so with our heart-action; we lie down at night fairly sure that there will be no break in the regular rhythm of its beat. the subconscious overseer is "on the job" and he never rests. no matter how hard we sleep, he never lets us forget to take a breath; and if we trust him, he is very likely to wake us up at the appointed time in the morning. also, if we trust him, he carries us off to sleep as though we were babies. has he not had long practice in the days before insomnia was invented? =first aid to the injured.= in times of infection or injury, this subconscious manager is better than any doctor. the doctors say with truth that they only assist nature. if the infection is internal, antitoxins are produced within the body. if the injury is external, like a cut, the messages fly, and white blood-corpuscles are marshaled to take care of poisons and build up the tissue. if the injury is of the kind that needs rest, the subconscious doctor knows it. he therefore causes pain and rigidity, in order to induce us to hold the injured part still until it is restored. crile reminds us of a fact that is often noticed by surgeons. if patients under ether are handled roughly, especially in the intestinal region, respiration quickens and there are tremors and even convulsive efforts which interfere with the surgeon's work. the conscious mind cannot feel. it is asleep. but the subconscious mind, whose business it is to protect the body, is trying to get away from injury. the body uses up as much energy as though it had run for miles, and when the patient wakes up, we say that he is suffering from shock. the subconscious mind which is not affected by ether, has been exhausting itself in a vain attempt to get the body away from harm. =a tireless servant.= when the conscious mind undertakes a job, it is always more or less subject to fatigue. but the subconscious after its long practice seems never to tire. we say that its activities have become automatic. with all its inherited skill, the subconscious, if left to itself, can be depended upon to run the bodily machinery without effort and without hitch. the only things that can interfere with its work are the wrong kind of emotions and the wrong kind of suggestions from the conscious mind. barring these, it goes its way like a trusty servant, looking after details and leaving its master's mind free for other things. having been "in the family" for generations, it knows its business and resents any interference with its duties or any infringement of its rights. no man, then, comes into this world without inheritance: he receives from his ancestors two goodly sets of heirlooms, the instincts and the mechanism which carries on bodily functions. this is the capital with which man starts life; but immediately he begins increasing this capital, adding memories from his own experience to the accumulated race-records. personal memories no more startling secret has been unearthed by science than the discovery of the length and minuteness of our memories. no matter how much one may think he has forgotten, the tablets of his mind are closely written with records of infinitesimal experiences, shadowy sensations, old happenings which the conscious self has lost entirely and would scarcely recognize as its own. many of these brain records, or neurograms, as prince calls them, are never aroused from their dormant conditions. but others, aroused by emotion or association of ideas, may after years of inactivity, come forth again either as conscious memories or as subconscious forces, or even as physiological memories,--bodily repetitions of the pains, palpitations, and tremors of old emotional experiences. =irresistible childhood.= an experience that is forgotten is not necessarily lost. although the first few years of childhood are lost to conscious memory, these years outweigh all others in their influence on character. the jesuit priest was right when he said, "give me a child until he is six years old, and he will be a catholic all his life." as frink has so ably shown, the determining factors that enter into any adult choice, such as the choice of the catholic or the protestant faith, are in a large measure made up of subconscious memories from early childhood, forgotten memories of sunday-school and church, of lessons at home or passages in books,--experiences which no voluntary effort could recall, but which still live unrecognized in our mature judgments and beliefs. naturally we do not acknowledge these subconscious motives. we like to believe that all our decisions are based on reason, and so we invent plausible arguments for our attitudes and our actions, arguments which we ourselves implicitly believe. this process of substituting a plausible reason for a subconscious one is known as rationalization, a process which every one of us engages in many times a day. it is indeed true that the child is father to the man. those first impressionable years, when we believed implicitly whatever any one told us and when through ignorance we reacted emotionally to ordinary experiences, are molding us still, making us the men and women we are to-day, coloring with childish ideas many of the attitudes of our supposedly reasoning life. bergson says: the unconscious is our historical past. in reality the past is preserved automatically. in its entirety probably it follows us at every instant; all that we have felt, thought and willed from our earliest infancy is there, leaning over the present which is about to join it, pressing against the portals of consciousness that would fain leave it outside. =spontaneous outbursts.= "how do we know all this?" some one says. "what is the evidence for these sweeping statements? if we cannot remember, how can we discover these strange memories that are so powerful but so elusive? if they are below the level of consciousness, are they not, in the very nature of the case, forever hidden from view, in the sphere of the occult rather than that of science?" the answer to these questions is determined by one important fact; the line between the conscious and subconscious minds does not always remain in the same place; the "threshold of consciousness" is sometimes displaced, automatically allowing these buried memories to come to the surface. in sleep and delirium, in trance and hallucination, in hysteria and intoxication, the tables are turned; the restraining hand of the conscious mind is loosened and the submerged self comes forth with all its ancient memories. it is a common experience to have a patient in delirium repeat long-forgotten verses or descriptions of events that the "real man" has lost entirely. the renowned servant-girl, quoted by hudson, who in delirium recited passage after passage of hebrew, latin, and greek, which she had heard her one-time master repeat in his study, is typical of many such instances.[20] [footnote 20: hudson: _the law of psychic phenomena_, p. 44. quoted from _coleridge's biographia literaria_, vol. i, p. 117 (edit. 1847).] a young girl of nineteen, a patient of mine, lapsed for several weeks into a dissociated state in which she forgot all the memories and ideas of her adult life, and returned to the period of her childhood. she used to say that she saw things inside her head and would accurately describe events that took place before she was two years of age,--scenes which she had completely forgotten in her normal life. one day when i asked her to tell me what she was seeing, she began to talk about "little sister" (herself) and "little brother." "little sister and brother were the two little folks that lived with their mother and their daddy and they were playing on the sand-pile. you know there was only one sand-pile, not like all the ones they have down here (at the seaside), and they had a bucket that they would put sand in and they would dump it out again and they would make nice things, you know; they would play with their little dog ponto and he was white with black and brown spots on him. little brother had white hair and he was bigger than little sister and he had a little waist with ruffles down the front and around the collar and a black coat that came down to his knees and it had two little white bands around it. some of the waists he wore had blue specks and some had red and black specks in it. "little sister had yellow curls and she had a blue coat with jiggly streaks of white in it, and she had a little white bonnet that was crocheted, and she had little blue mittens on that were tied to a string that went around her neck and down the other arm. it got pretty cold where they lived. little sister and little brother would go out to the pile of leaves and jump on them and bounce and they would crackle. the leaves came down from the trees all of a sudden when they got tired, and they were different colors, brown and red. little sister could walk then but she could not walk one other time before then; she could stand up by holding to a chair, but she could not go herself. one morning big tom said 'run to daddy' and she went to her daddy, and after that she always walked; they were glad and she was glad. she walked all day long. big tom was a man who used to help daddy and little sister always liked him. he was a nice man." the mother verified this scene of the first walking, saying that it had occurred on her own wedding-anniversary when the child was twenty-three months old. one night i heard the same patient talk in her sleep in the slow and hesitating manner of a child reading phonetically from a printed page. i soon recognized the words as those of a poem of tagore's, called "my prayer," and remembered that a magazine containing the poem had been lying on the bed during the day. when she had finished i wakened her, saying, "now tell me what you have been dreaming." she answered in her childish way, "i think i do not dream." she went to sleep immediately and again repeated the poem, word for word, without a single mistake. again i awakened her with the words, "now tell me what you have been dreaming." and again she answered, "i think i do not dream." i said: "but yes; don't you remember you were just saying, 'when the time comes for me to go'?" (the last line of the poem). "oh, yes," she said, "i was seeing it, and i think i'll not go to sleep again. it tires me so to see it." while she was awake she had no recollection of having seen the poem and was indeed in her dissociated state quite incapable of understanding its meaning. asleep, she saw every word as plainly as if the page had been before her eyes. the distorted pictures of dreams are always made of the material which past experiences have furnished and which have in many cases been dropped out of consciousness for years only to rise out of their long oblivion when the conscious mind has been put to sleep. =unearthing old experiences.= however, psychology does not have to wait for buried memories to come forth of their own free will. it has a number of successful ways of summoning them from their hiding-place and helping them across the line into consciousness. in the hands of skilled investigators and therapeutists, hypnosis, hypnoidization, automatic writing, crystal-gazing, abstraction, free association, word-association, and interpretation of dreams have all been repeatedly successful in bringing to light memories which apparently have been for many years completely blotted out of mind. as we become better acquainted with these technical devices we shall find that there are four kinds of experiences whose records are carefully stored away in our minds. some were always so far from the center of our attention that we could swear they never had been ours; others, although once present in consciousness, were so trivial and unimportant that it seems ridiculous to suppose them conserved; others never came into our waking minds at all and entered our lives only in special states, such as sleep or delirium or dreams. all these we should expect to forget; the astonishing thing is that they ever were conserved. but there is a fourth class that is different. it is made up of experiences that were so vital, so emotional, so closely woven into the fiber of our being that it seems impossible that they ever could be forgotten. let us look at a few examples of records of all these four kinds of experiences, examples chosen from hundreds of their kind as illustrations of the all-embracing character of buried memories.[21] [footnote 21: for further examples see prince, _the unconscious_; prince, _the dissociation of a personality_, and hudson, _the law of psychic phenomena_.] =out of the corners of our eyes.= in the first place, we are much more observing than we imagine. we may be so interested in our own thoughts that details of our environment are entirely lost on the conscious mind, but the subconscious has its eyes open, and its ears. people in hypnosis have been known to repeat verbatim whole passages from newspapers which they had never consciously read. while they were busy with one column, their wide-awake subconscious was devouring the next one, and remembering it. prince relates the story of a young woman who unconsciously "took in" the details of a friend's appearance: i asked b.c.a. (without warning and after having covered her eyes) to describe the dress of a friend who was present and with whom she had been conversing perhaps some twenty minutes. she was unable to do so beyond saying that he wore dark clothes. i then found that i myself was unable to give a more detailed description of his dress, although we had lunched and been together about two hours. b.c.a. was then asked to write a description automatically. her hand wrote as follows (she was unaware that her hand was writing): "he has on a dark greenish gray suit, a stripe in it--little rough stripe; black bow cravat; shirt with three little stripes in it; black laced shoes; false teeth; one finger gone; three buttons on his coat." the written description was absolutely correct. the stripes in the coat were almost invisible. i had not noticed his teeth or the loss of a finger and we had to count the buttons to make sure of their number owing to their partial concealment by the folds of the unbuttoned coat. the shoe-strings i am sure under the conditions would have escaped nearly every one's notice.[22] [footnote 22: prince: _the unconscious_, p. 53.] automatic writing, the method used to uncover this subconscious perception, is a favorite method with some investigators and is often used by morton prince. the hand writes without the direction of the personal consciousness and usually without the person's being aware that it is writing. a dissociated person does this very easily; other people can cultivate the ability, and perhaps most of us approach it when we are at the telephone, busily writing or drawing remarkable pictures while the rest of us is engaged in conversation. the present epidemic of the ouija board shows how many persons there are who are able to switch off the conscious mind and let the subconscious control the muscles that are used in writing. the fact that the writer has no understanding of what he is doing and believes himself directed by some outside power, in no way interferes with the subconscious phenomenon. =everyday doings.= besides perceptions which were originally so far from the focus of attention that the conscious mind never caught them at all, there are the little experiences of everyday life, fleeting thoughts and impressions which occupy us for a minute and then disappear. every experience is a dynamic fact and no matter how trivial the experience may be or how completely forgotten, it still exists as a part of the personality. an amusing example of the everyday kind of forgotten experience occurred during the writing of this chapter. i wrote a sentence which pleased me very well. this is the sentence: "in the esthetic processes of evolution they [man's desires] have sunk below the surface as soon as formed, and have been covered over by an elastic and snug-fitting consciousness as the skin covers in the tissues and organs of the body." after showing this passage to my collaborator and remarking that this figure had never been used before, i was partly chagrined and partly amused to have her bring me the following sentence from white and jelliffe: "consciousness covered over and obscured the inner organs of the psyche just as the skin hides the inner organs of the body from vision." my originality had vanished and i was close to plagiarism. indeed, if a history of plagiarism could be written, it would probably abound in just such stories. i had read the article containing this sentence only once, about three years before, and had never quoted it or consciously thought of it. it had lain buried for three years, only to come forth as an original idea of my own. who knows how many times we all do just this thing without catching ourselves in the trick? =back-door memories.= there are other kinds of memories which hide in the subconscious, memories of experiences which have not come in by the front door, but have entered the mind during special states, such as sleep, delirium, intoxication, or hypnosis. what is known as post-hypnotic suggestion is the functioning of a suggestion received during hypnosis and emerging later as an impulse without being recognized as a memory. a man in a hypnotic state is told that at five o'clock he will take off his clothes and go to bed, without remembering that such a suggestion has been given him. he awakens with no recollection of the suggestion, but at five o'clock he suddenly feels impelled to go to bed, even though his unreasonable desire puts him into a highly embarrassing position. the suggestion, to be thus effective, must have been conserved somewhere in his mind outside of consciousness. suggestions that enter the mind during the normal sleep are also recorded,--a fact that carries a warning to people who are in the habit of talking of all sorts of matters while in the room with sleeping children. i have sometimes suggested to sleeping patients that on waking they will remember and tell me the cause of their symptoms. the following example shows not only the conservation of impressions gained in sleep, but also the sway of forgotten ideas of childhood, still strong in mature years. this young woman, a trained nurse, with many marked symptoms of hysteria, had been asked casually to bring a book from the public library. she cried out in consternation, "oh, no, i am afraid!" after a good deal of urging she finally brought the book, although at the cost of considerable effort. later, while she was taking a nap, i said to her, "you will not remember that i have talked to you. you will stay asleep while i am talking and while you are asleep there will come to your mind the reasons why you are afraid to go to the public library. when you waken, you will tell me all about it." upon awakening, she said: "oh, do you know, i can tell you why i have always been afraid to go to the public library. while i was in parochial school, father ---used to come in and tell us children to use the books out of the school library and never to go to the public library." i questioned her concerning her idea of the reason for such an injunction and what she thought was in the books which she was told not to read. she hesitatingly stated that it was her idea, even in childhood, that the books dealt with topics concerning the tabooed subject of the birth of children and kindred matters. =smoldering volcanoes.= let us now consider those emotional experiences which seem far too compelling to be forgotten, but which may live within us for years without giving any evidence of their existence. memories like these are apt to be anything but a dead past. many of my own patients have uncovered emotional memories through simply talking out to me whatever came into their minds, laying aside their critical faculty and letting their minds wander on into whatever paths association led them. this is known as the free-association method, and simple as it seems, is one of the most effective in uncovering memories which have been forgotten for years. one of my patients, a refined, highly educated woman of middle age, had suffered for two years with almost constant nausea. one day, after a long talk, with no suggestion on my part, only an occasional, "what does that remind you of?" she told with great emotion an experience which she had had at eighteen years of age, in which she had for a moment been sexually attracted to a boy friend, but had recoiled as soon as she realized where her impulse was leading her. she had been so horrified at the idea of her degradation, so nauseated at what she considered her sin, that she had put it out of her mind, denied that such a thought had ever been hers, repressed the desire into the subconscious, where it had continued to function unsatisfied, unassimilated with her mature judgments. her nausea was the symbol of a moral disgust. physical nausea she was willing to acknowledge, but not this other thing. upon reciting this old experience, with every sign of the original shame, she cried: "oh, doctor! why did you bring this up? i had forgotten it. i haven't thought of it in thirty years." i reminded her that i couldn't bring it up,--i had never known anything about it. with the emotional incoming of this memory and the saner attitude toward it which the mature woman's mind was able to take, the nausea disappeared for good. this case is typical of the psycho-neuroses and we shall have occasion to refer to it again. the present emphasis is on the fact that an emotional memory may be buried for many years while it still retains the power of reappearing in more or less disguised manifestation. =repressed memories.= if we ask how so burning a memory could escape from the consciousness of a grown woman, we are driven to the conclusion that this forgetting can be the result of no mere quiet fading away, but that there must have been some active force at work which kept the memory from coming into awareness. it was not lost. it was not passive. out of sight was not out of mind. there must have been a reason for its expulsion from the personal consciousness. in fact, we find that there is a reason. we find that whenever a vital emotional experience disappears from view, it is because it is too painful to be endured in consciousness. nor is it ever the pain of an impersonal experience or even the thought of what some one else has done to us that drives a memory out of mind. as a matter of fact, we never expel a memory except when it bears directly on ourselves and on our own opinion of ourselves. we can stand almost anything else, but we cannot stand an idea that does not fit in with our ideal for ourselves. this is not the pious ideal that we should like to live up to and that we hope to attain some day, not the ideal that we think we ought to have--like never speaking ill of others or never being selfish--but the secret picture that each of us has, locked away within him, the specifications of ourselves reduced to their lowest terms, below which we cannot go. energized by the instinct of positive self-feeling, and organized with the moral sentiments which we have acquired from education and the ideals of society, especially those acquired in early childhood, this ideal of ourselves becomes incorporated into our conscience and is an absolute necessity for our happiness. we have found that when two emotions clash, one drives out the other. so in this case, the woman's positive self-feeling of self-respect, combined with disgust, drove from the field that other emotion of the reproductive instinct which was trying to get expression. speaking technically, one repressed the other. the woman said to herself, "no, i never could have had such a thought," and promptly forgot it. needless to say, this kind of handling did not kill the impulse. buried in the depths of her soul, it continued to live like a live coal, until in later years, fanned by the wind of some new experience, it burst into flame. in this case the wish had originally flashed into awareness for an instant, but very often the impulse never gets into consciousness at all. the upper layers of the subconscious, where the acquired ideals live, automatically work to keep down any desires which are thought to be out of keeping with the person as he knows himself. he then would emphatically deny that such desires had ever had any place in his life. freud has called this repressing force the psychic censor. to get into consciousness, any idea from the subconscious must be able to pass this censor. this force seems to be a combination of the self-regarding and herd-instincts, which dispute with the instinct for reproduction the right to "the common path" for expression. a considerable part of any person's subconscious is made up of memories, wishes, impulses, which are repressed in this way. of course any instinctive desire may be repressed, but it is easy to understand why the most frequently denied impulse, the instinct of reproduction, against whose urgency society has cultivated so strong a feeling, should be repressed more frequently than any other.[23] [footnote 23: see foot-note, p. 145, chap. vii.] =past and present.= it matters not, then, in what state experiences come to us, whether in sleep or delirium, intoxication or hypnosis, or in the normal waking condition. they are conserved and may exert great influence on our normal lives. it matters not whether the experiences be full of meaning and emotion or whether they be so slight as to pass unnoticed, they are conserved. it matters not whether these experiences be mere sense-impressions, or inner thoughts, whether they be unacknowledged hopes or fears, undesirable moods and unworthy desires or fine aspirations and lofty ideals. they are conserved and they may at a later day rise up to bless or to curse us long after we had thought them buried in the past. the present is the product of the past. it is the past plus an element of choice which keeps us from settling down in the despair of fatalism and enables us to do something toward making the present that is, a help and not a stumbling-block to the present that is to be. some habits of the subconscious =the association of ideas.= it is only by something akin to poetic license that we can speak of lower and higher strata of mind. when we carry over the language of material things into the less easily pictured psychic realm, it is sometimes well to remind ourselves that figures of speech, if taken too literally, are more misleading than illuminating. when we speak of the deep-laid instinctive lower levels of mind and the higher acquired levels, we must not imagine that these strata are really laid in neat, mutually exclusive layers, one on top of the other in the chambers of the mind. nor must we imagine the mental elements of instinct, idea, and memory as jumbled together in chaotic confusion, or in scattered isolated units. as a matter of fact, the best word to picture the inside of our minds is the word "group." we do not know just how ideas and instincts can group themselves together, but we do know that by some arrangement of brain paths and nerve-connections, the laws of association of ideas and of habit take our mental experiences and organize them into more or less permanent systems. instinctive emotions tend to organize themselves around ideas to form sentiments; ideas or sentiments, which through repetition or emotion are associated together, tend to stay together in groups or complexes which act as a whole; complexes which pertain to the same interests tend to bind themselves into larger systems or constellations, forming moods, or sides to one's character. it is not highly important to differentiate in every case a sentiment from a complex, or a complex from a constellation, especially as many writers use "complex" as the generic term for all sorts of groups; but a general understanding of the much-used word "complex" is necessary for a comprehension of modern literature on psychology, psychotherapy or general education. "=what is a complex=?" reduced to its lowest terms, a complex is a group. it may be simply a group of associated movements, like lacing one's shoes or knitting; it may be a group of movements and ideas, like typewriting or piano-playing, which through repetition have become automatic or subconscious; it may be merely a group of ideas, such as the days of the week, the alphabet or the multiplication table. in all these types it is repetition working through the law of habit that ties the ideas and movements together into an organic whole. usually, however, the word complex is reserved for psychic elements that are bound together by emotion. in this sense, a complex is an emotional thought-habit. frink's definition, which is one of the simplest, recognizes only this emotional type: "a complex is a system of connected ideas, having a strong emotional tone, and displaying a tendency to produce or influence conscious thought and action in a definite and predetermined direction."[24] [footnote 24: frink: "what is a complex?" _journal american medical assoc_., vol. lxii, no. 12, mar. 21, 1914.] emotion and repetition are the great welders of complexes. emotion is the strongest cement in the world. a single emotional experience suffices to bind together ideas that were originally as far apart as the poles. sometimes a complex includes not only ideas, movements, and emotions, but physiological disturbances and sensations. some people cannot go aboard a stationary ship without vomiting, nor see a rose, even though it prove to be a wax one, without the sneezing and watery eyes of hay-fever. this is what is known as a "conditioned reflex." past associations plus fear have so welded together idea and bodily manifestation that one follows the other as a matter of course, long after the real cause is removed. in such ways innumerable nervous symptoms arise. the same laws which form healthy complexes, and, indeed, which make all education possible, may thus be responsible for the unhealthy mal-adaptive association-habits which lie back of a neurosis. fortunately, a knowledge of this fact furnishes the clue to the re-education that brings recovery. a complex may be either conscious or unconscious, but as it usually happens that either all or part of its elements are below the surface, the word is oftenest used to mean those buried systems of the subconscious mind that influence thought or behavior without themselves being open to scrutiny. it is these buried complexes, memory groups, gathered through the years of experience, that determine action in uniform and easily prophesied directions. every individual has a definite complex about religion, about politics, about patriotism, about business, and it is the sum of these buried complexes which makes up his total personality. =displacement.= association or grouping is, then, an intrinsic power of mind; but as all life seems to be built on opposites--light and darkness, heat and cold, love and hate--so mind, which is capable of association, is capable also of displacement or the splitting apart of elements which belong together. there is such a thing as the simple breaking up of complexes, when education or experience or neglect separate ideas and emotions which had been previously welded together; but displacement is another matter. here there is still a path between idea and emotion; they still belong to the same complex, but the connection is lost sight of. the impulse or emotion attaches itself to another substitute idea which is related to the first but which is more acceptable to the personality. sometimes the original idea is forgotten; repressed, or dissociated into the subconscious, as in anxiety neurosis; and sometimes it is merely shorn of its emotional interest and remembered as an unrelated or insignificant idea, as in compulsion neurosis. =transference.= another kind of displacement which seems hard to believe possible until it is repeatedly encountered in intelligent human beings is the process called transference, by which everybody at some time or other acts toward the people he meets, not according to rational standards but according to old unconscious attitudes toward other people. each of us carries, within, subconscious pictures of the people who surrounded us when we were children; and now when we meet a new person we are likely unconsciously to say to ourselves--not, "this person has eyebrows like my mother, or a voice like my nurse," or, "this person bosses me around as my father used to do," but, "this is my mother, this is my nurse, this is my father." whereupon we may proceed to act toward that person very much as we did toward the original person in childhood. transference is subconsciously identifying one person with another and behaving toward the one as if he were that other. analysis has discovered that many a man's hostile attitude toward the state or religion or authority in general, is nothing more than this kind of displacement of his childhood's attitude toward authority in the person of his perhaps too-domineering father. many a woman has married a husband, not for what he was in himself, but because she unconsciously identified him with her childish image of her father. students of human nature have always recognized the kind of displacement which transfers the sense of guilt from some major act or attitude to a minor one which is more easily faced, just as _lady macbeth_ felt that by washing her hands she might free herself from her deeper stain. this is a frequent mechanism in the psychoneuroses--not that neurotics are likely to have committed any great crime, but that they feel subconsciously that some of their wishes or thoughts are wicked. =the phenomena of dissociation.= when an idea or a complex, a perception or a memory is either temporarily or permanently shoved out of consciousness into the subconscious, it is said to be dissociated. when we are asleep, the part of us that is usually conscious is dissociated and the submerged part takes the stage. when we forget our surroundings in concentration or absent-mindedness, a part of us is dissociated and our friends say that we are "not all there," or as popular slang has it, "nobody home." when a mood or system of complexes drives out all other moods, one becomes "a different person." but if this normal dissociation is carried a step farther, we may lose the power to put ourselves together again, and then we may truly be said to be dissociated. almost any part of us is subject to this kind of apparent loss. in neurasthenia the happy, healthy complexes which have hitherto dominated our lives may be split off and left lying dormant in the subconscious; or the power of will or concentration may seem to be gone. in hysteria we may seem to lose the ability to see or feel or walk, or we may lose for the time all recollection of certain past events, or of whole periods of our lives, or of everything but one system of ideas which monopolizes the field of attention. sometimes great systems of memories, instincts, and complexes are alternately shifted in and out of gear, leaving first one kind of person on top and then another.[25] stevenson's _dr. jekyll_ and _mr. hyde_ is not so fantastic a character as he seems. any one who doubts the ability of the mind to split itself up into two or more distinct personalities, entertaining totally different conceptions of life, disliking each other, playing tricks on each other, writing notes to each other, and carrying on a perpetual feud as each tries to get the upper hand, should read morton prince's "dissociation of a personality," a fascinating account of his famous case, miss beauchamp. [footnote 25: when a memory or system of memories is suddenly lost from consciousness the person is said to be suffering from amnesia or pathological loss of memory.] =internal warfare.= conflict, often accentuated by shock or fatigue, represses or drives down certain ideas, perceptions, wishes, memories, or complexes into the subconscious, where they remain, sometimes dormant and passive but often dynamic, emotional, carrying on an over-excited, automatic activity, freed from the control of reason and the modifying influence of other ideas, and able to cause almost any kind of disturbance. so long as there is team-work between the various parts of our personality we are able to act as a unit; but just as soon as we break up into factions with no communication between the warring camps, so soon do we become quite incapable of coã¶rdination or adjustment, like a nation torn by civil war. many of the seemingly fantastic and bizarre mental phenomena of which a human being is capable are the result of this kind of disintegration. however, nature has a remarkable power for righting herself, and it is only under an accumulation of unfortunate circumstances that there appears a neurosis, which is nothing more than a functioning of certain parts of the personality with all the rest dissociated. we shall later inquire more fully into the causes that lead up to such a result and shall find that the mechanisms involved are these processes of organization and disorganization by which mind is wont to group together or separate the various elements within its borders. summary gathering up our impressions, we find a number of outstanding qualities which we may summarize in the following way: the subconscious is: _1 vast yet explorable_ the fraction that could accurately show the relation of the conscious to the unconscious part of ourselves would have such a small numerator and such a huge denominator that we might well wonder where consciousness came in at all.[26] some one has likened the subconscious to the great far-reaching depths of the mammoth cave, and consciousness to the tiny, flickering lamp which we carry to light our way in the darkness. however, ever the subconscious mind is becoming explorable, and it may be that science is giving the tiny lamp the revealing power of a great searchlight. [footnote 26: "the entire active life of the individual may be represented by a fraction, the numerator of which is any particular moment, the denominator is the rich inheritance of the past."--jelliffe: "the technique of psychoanalysis," _psychoanalytic review,_ vol. iii, no. 2, p. 164.] _2 ancient yet modern_ the lowest layers of the subconscious, represented by the instincts, are as old as life itself, with their lineage reaching back in direct and unbroken line to the first living things on the ooze of the ocean floor. the higher strata are more modern, full, and accurate records of our own lifetime, beginning with our first cry and ending with to-day's thoughts. _3 primitive yet refined_ the lowest level, representing the past of the race, is primitive like a savage, and infantile, like a child; it is instinctive, unalterable, and universal; it knows no restraint, no culture, and no prudence. the higher level, the storehouse of individual experience, bears the marks of acquired ideals, of cultivated refinement, and represents among other things the precepts and prudence of civilized society. _4 emotional yet intellectual_ our records of the past are not dead archives, but living forces--persistent, urging, dynamic and emotional. they give meaning to new experiences, color our judgments, shape our beliefs, determine our interests, and, if wrongly handled, make their way into consciousness as neurotic symptoms. however, the subconscious is not all emotion. it is a mind capable of elaborate thought, able to calculate, to scheme, to answer doubts, to solve problems, to fabricate the purposeful, fantastic allegories of dreams and to create from mere knowledge the inspired works of genius. but the subconscious has one great limitation, it cannot reason inductively. given a premise, this mind can reason as unerringly as the most skilful logician; that is, it can reason deductively, but it cannot arrive at a general conclusion from a number of particular facts. however, except for inductive reasoning and awareness, the subconscious seems to possess all the attributes of conscious mind and is in fact an intellectual force to be reckoned with. _5 organized yet disorganizable_ the subconscious mind is a highly organized institution, but like all such institutions it is liable to disorganization when rent by internal dissension. ordinarily it keeps its ideas and emotions, its complexes and moods in fairly accurate order, but when upset by emotional warfare, it gets its records confused and falls into a chaotic state which makes regular business impossible. _6 masterful yet obedient_ the subconscious, which is master of the body, is in normal life the servant of consciousness. one of its outstanding qualities is suggestibility. since it cannot reason from particulars to a general conclusion it takes any statement given it by consciousness, believes it implicitly and acts accordingly. the pilot wheel of the ship is, after all, the conscious mind, insignificant in size when compared with the great mass of the vessel, but all-powerful in its ability to direct the course of the voyage. nervous persons are people who are too much under the sway of the subconscious; so, too, are some geniuses, who narrowly escape a neurosis by finding a more useful outlet for their subconscious energies. while the poet, the inventor, and the neurotic are likely to be too largely controlled by the subconscious, the average man is to a greater extent ruled by the conscious mind; and the highest type of genius is the man whose conscious and subconscious minds work together in perfect harmony, each up to its full power. if, as many believe, the next great strides of science are to be in this direction, it may pay some of us to be pioneers in learning how to make use of these undeveloped riches of memory, organization, and surplus energy. the subconscious, which can on occasion behave like a very devil within us, is, when rightly used, our greatest asset, the source of powers whose appearance in the occasional individual has been considered almost superhuman, but which prove to be characteristically human, the common inheritance of the race of man. chapter vi _in which we learn why it pays to be cheerful_ body and mind the missing link =ancient knowledge.= people have always known that mind in some strange way carries its moods over into the body. the writer of the book of proverbs tells us, from that far-off day, that "a merry heart doeth good like a medicine, but a broken spirit drieth the bones." jesus in his healing ministry always emphasized the place of faith in the cure of the body. "thy faith hath made thee whole," is a frequent word on his lips, and ever since his day people have been rediscovering the truth that faith, even in the absence of a worthy object, does often make whole. faith in the doctor, the medicine, the charm, the mineral waters, the shrine, and in the good god, has brought health to many thousands of sufferers. people have always reckoned on this bodily result from a mental state. they have intuitively known better than to tell a sick person that he is looking worse, but they have not always known why. they have known that a fit of anger is apt to bring on a headache, but they have not stopped to look for the reason, or if they have, they have often gotten themselves into a tangle. this is because there has always been, until recently, a missing link. now the link has been found. after the last chapter, it will not be hard to understand that this connecting link, this go-between of body and mind, is nothing else than the subconscious mind. when we remember that it has the double power of knowing our thoughts and of controlling our bodies, it is not hard to see how an idea can translate itself into a pain, nor to realize with new vividness the truth of the statement that healthy mental states make for health, and unhealthy mental states for illness. =suggestion and emotion.= there are still many gaps in our knowledge of the ways of the subconscious, but investigation has thrown a good deal of light on the problem. two of the principles already discussed are sufficient to explain most of the phenomena. these are, first, that the subconscious is amenable to control by suggestion, and secondly, that it is greatly influenced by emotion. tracing back the principles behind any example of the power of mind over body, one finds at the root of the matter either a suggestion or an emotion, or both. if, then, the stimulating and depressing effects of mental states are to be understood, the first step must be a fuller understanding of the laws governing suggestion and emotion. the contagion of ideas one of the most important points about the subconscious mind is its openness to suggestion. it likes to believe what it is told and to act accordingly. the conscious mind, too,--proud seat of reason though it may be,--shares this habit of accepting ideas without demanding too much proof of their truth. even at his best, man is extremely susceptible to the contagion of ideas. most of us are even less immune to this mental contagion than we are to colds or influenza; for ideas are catching. they are such subtle, insinuating things that they creep into our minds without our knowing it at all; and once there, they are as powerful as most germs. let a person faint in a crowded room, and a good per cent. of the women present will begin to fan themselves. the room has suddenly become insufferably close. after we have read half a hundred times that ivory soap floats, a fair proportion of the population is likely to be seized with desire for a soap that floats,--not because they have any good reason for doing so, but simply because the suggestion has "taken." as for the harbingers of spring, they are neither the birds nor the wild flowers, but the blooming windows of the milliners, which successfully suggest in wintry february that summer is coming, and that felt and fur are out of season. it is evident that all advertising is suggestion. the training of children, also, if it is done in the right way, is largely a matter of suggestion. the little child who falls down and bumps his head is very likely to cry if met with a sympathetic show of concern, while the same child will often take his mishaps as a joke if his elders meet them with a laugh or a diverting remark. unlucky is the child whose mother does not know, either consciously or intuitively, that example and contagion are more powerful--and more pleasant--than command and prohibition. =everything suggestive.= human beings are constantly communicating, one to another. sometimes they "get over" an idea by means of words, but often they do it in more subtle ways,--by the elevation of an eyelid, the gesture of a hand, composure of manner in a crisis, or a laugh in a delicate situation. a suggestion is merely an idea passed from one person to another, an idea that is accepted with conviction and acted upon, even though there may be no logic, no reason, no proof of its truth. it is an influence that takes hold of the mind and works itself out to fulfilment, quite apart from its worth or reasonableness. of course, logical persuasion and argument have their place in the communication of ideas; an idea may be conveyed by other ways than suggestion. but while suggestion is not everything, it is equally true that there is suggestion in everything. the doctor may give a patient a very rational explanation of his case, but the doubtful shake of the head or the encouraging look of his eye is quite likely to color the patient's general impression. the eyes of our subconscious are always open, and they are constantly getting impressions, subtle suggestions that are implied rather than expressed. =abnormal suggestibility.= while everybody is suggestible, nervous people are abnormally so. it may be, as mcdougall suggests, that they have so large an amount of submission or negative self-feeling in their make-up that they believe anything, just because some one else says it is true. sometimes it is lack of knowledge that makes us gullible, and at other times the cause of our suggestibility is failure to use the knowledge that we have. sometimes our ideas are locked away in air-tight compartments with no interaction between them. the psychologists tell us that suggestion is greatly favored by a narrowing of the attention, a "contraction of the field of consciousness," a dissociation of other ideas through concentration. this all simply means that we forget to let our common sense bring to bear counter ideas that might challenge a false one; or that worry--a veritable "spasm of the attention"--has fixed upon an idea to the exclusion of all others; or that through fatigue or the dissociation of sleep or hypnosis or hysteria, our reasoning powers have been locked out and for the time being are unable to act. it was through experiments on hypnotized subjects that scientists first learned of the suggestibility of the subconscious mind. in hypnosis a person can be made to believe almost anything and to do almost anything compatible with the safety and the moral sense of the individual. the instinct of self-preservation will not allow the most deeply hypnotized person to do anything dangerous to himself; and the moral complexes, laid in the subconscious, never permit a person to perform in earnest an act of which the waking moral sense would disapprove. within these limits, a person in the dissociated hypnotic state can be made to accept almost any suggestion. we found in the last chapter how open to suggestion is a person in normal sleep. of the dissociation of hysteria we shall have occasion to speak in later chapters. although all these special states heighten suggestibility, we must not forget how susceptible each of us is in his normal waking state. =living its faith.= all this gathers meaning only when we realize that ideas are dynamic. they always tend to work themselves out to fulfilment. the subconscious no sooner gets a conviction than it tries to act it out. of course it can succeed only up to a certain limit. if it believes the stomach to have cancer, it cannot make cancer, but it can make the stomach misbehave. one of my patients, on hearing of a case of brain-tumor immediately imagined this to be her trouble, and developed a pain in her head. she could not manufacture a tumor, but she could manufacture what she believed to be the symptoms. there was another patient who was supposed to have brain-tumor. this young woman seemed to have lost almost entirely the power to keep her equilibrium in walking. her center of gravity was never over her feet, but away out in space, so that she was continually banging from one side of the room to the other, only saving herself from injury by catching at the wall or the furniture with her hands. several physicians who had been interested in the case had found the symptoms strongly suggestive of brain-tumor. there were, however, certain unmistakable earmarks of hysteria, such as childlike bland indifference to the awkwardness of the gait which was a grotesque caricature of several brain and spinal-cord diseases, with no accurate picture of any single one. this was evidently a case, not of actual loss of power but a dissociation of the memory-picture of walking. the patient was a trained nurse and knew in a general way the symptoms of brain-tumor. when the suggestion of brain-tumor had fixed itself in her mind she was able subconsciously to manufacture what she believed to be the symptoms of that disease. by injecting a keen sense of disapprobation and skepticism into the hitherto placidly accepted state of disability, by flashing a mirror on the physical and moral attitudes which she was assuming, i was able to rob the pathological complex of its (altogether unconscious) pleasurable feeling-tone, and to restore to its former strength and poise a personality of exceptional native worth and beauty. after a few weeks at my house she was able to walk like a normal person and went back to her work, for good. we have already learned enough about the inner self to see in a faint way how it works out its ideas. since the subconscious mind runs the bodily machinery, since it regulates digestion, the building up of tissue, circulation, respiration, glandular secretion, muscular tonus, and every other process pertaining to nutrition and growth, it is not difficult to see how an idea about any of these matters can work itself out into a fact. a thought can furnish the mental machinery needed to fulfil the thought. some one catches the suggestion: "concentration is hard on the brain. it soon brings on brain-fag and headache." not knowing facts to the contrary, the suggestible mind accepts the proposition. then one day, after a little concentration, the idea begins to work. whereupon the autonomic nervous system tightens up the blood-vessels that regulate the local blood supply, too much blood stays in the head, and lo, it aches! the next time, the suggestion comes with greater force, and soon the habit is formed,--all the result of an idea. it is a good thing to remember that constant thought about any part of the body never fails to send an over-supply of blood to that part; of course that means congestion and pain. =hands off!= by sending messages directly to an organ through the nerve-centers or by changing circulation, the subconscious director of our bodies can make any part of us misbehave in a number of ways. all it needs is a suggestion of an interfering thought about an organ. as we have insisted before, the subconscious cannot stand interference. sadler well says: "man can live at the equator or exist at the poles. he can eat almost anything and everything, but he cannot long stand self-contemplation. the human mind can accomplish wonders in the way of work, but it is soon wrecked when directed into the channels of worry."[27] in other words, hands off!--or rather, minds off! don't get ideas that make you think about your body. the surest way to disarrange any function is to think about it. it is a stout heart that will not change its beat with a frequent finger on the pulse, and a hearty stomach that will not "act up" under attention. "judicious neglect" is a good motto for most occasions. take no anxious thought if you would be well. know enough about your body to counteract false suggestions; fulfil the common-sense laws of hygiene,--eight hours in bed, plenty of exercise and fresh air, and three square meals a day. then forget all about it. "a mental representation is already a sensation,"[28] and we have enough legitimate sensations without manufacturing others. [footnote 27: sadler: _physiology of faith and fear_.] [footnote 28: dubois: _psychic treatment of nervous disorders_.] =from real life.= startling indeed are the tricks that we can play on ourselves by disregarding these laws. a patient who was unnecessarily concerned about his stomach once came to me in great alarm, exhibiting a distinct, well-defined swelling about the size of a match-box in the region of his stomach. i looked at it, laughed, and told him to forget it. whereupon it promptly disappeared. the first segment of the rectus muscle had tied itself up into a knot, under the stimulus of anxious attention. another patient appeared at my door one day saying, "look here!" examination showed that her abdomen was swollen to the size of more than a six-months pregnancy. as it happened, this woman had a friend who a short time before had developed a pseudo, or hysterical pregnancy which continued for several months. my patient, accepting the suggestion, was prepared to imitate her. i gave her a punch or two and told her to go and dress for luncheon. in the afternoon she had returned to her normal size. another woman, suffering from chronic constipation, was firmly convinced that her bowels could not move without a cathartic, which i refused to give. however, i did give her some strychnine pills, carefully explaining that they were not for her intestines and that they would have no effect there. she did not believe me, and promptly began to have an evacuation every day. it seems that sometimes two wrong ideas are equal to a right one. if doctors fully realized the power of suggestion, they would be more careful than they sometimes are about suggesting symptoms by the questions they ask their patients. a patient of mine with locomotor-ataxia suffered from the usual train of symptoms incident to that disease. it turned out, however, that many of the symptoms had been suggested by the questions of former physicians who had asked him whether he had certain symptoms and certain disabilities. the patient had answered in the negative and then promptly developed the suggested symptoms. when i told him what had happened, these false symptoms disappeared leaving only those which had a real physical foundation. another patient, a young girl, complained of a definite localized pain in her arm, and told me that she was suffering from angina pectoris. as we do not expect to find this disease in a young person, i asked her where she got such an idea. "dr. ---told me so last may." "did you feel the pain in this same place before that time?" i asked. she thought a minute and then answered: "why no, i had a pain around my heart but i did not notice it in my arm until after that consultation." the wise physician lets his patients describe their own symptoms without suggesting others by the implication of his questions. =autosuggestion.= of course we must remember that an idea cannot always work itself out immediately. conditions are not always ripe. it often lies fallow a long time, buried in the subconscious, only to come up again as an autosuggestion, a suggestion from the self to the self. if some one tells us that nervous insomnia is disastrous, and we believe it, we shall probably store up the idea until the next time that chance conditions keep us awake. then the autosuggestion "bobs up," common sense is side-tracked, we toss and worry--and of course stay awake. an autosuggestion often repeated becomes the strongest of suggestions, successfully opposing most outside ideas that would counteract it,--reason enough for seeing to it that our autosuggestions are of the healthful variety. at the base of every psycho-neurosis is an unhealthful suggestion. this is never the ultimate cause. there are other forces at work. but the suggestion is the material out of which those other forces weave the neurosis. suggestibility is one of the earmarks of nervousness. a sensible and sturdy spirit, stable enough to maintain its equilibrium, is a fairly good antidote to attack. "as a man thinketh in his heart, so is he." why feelings count =the emotions again.= it seems impossible to discuss any psychological principle without finally coming back to the subject of emotions. it truly seems that all roads lead to the instincts and to the emotions which drive them. and so, as we follow the trail of suggestion, we suddenly turn a corner and find ourselves back at our starting-point--the emotional life. like all other ideas, suggestions get tied up with emotions to form complexes, of which the driving-power is the emotion. if we look into our emotional life, we find, besides the true emotions, with which we have become familiar in chapter iii, a great number of feelings or feeling-tones which color either pleasurably or painfully our emotions and our ideas. on the one hand there are pleasure, joy, exaltation, courage, cheer, confidence, satisfaction; and on the other, pain, sorrow, depression, apprehension, gloom, distrust, and dissatisfaction. every complex which is laid away in our subconscious is tinted, either slightly or intensely, with its specific feeling-tone. =emotions--tonic and poisonous.= all this is most important because of one vital fact; joyful emotions invigorate, and sorrowful emotions depress; pleasurable emotions stimulate, and painful emotions burden; satisfying emotions revitalize, and unsatisfying emotions sap the strength. in other words, our bodies are made for courage, confidence, and cheer. any other atmosphere puts them out of their element, handicapped by abnormal conditions for which they were never fashioned. we were written in a major key, and when we try to change over into minor tones we get sadly out of tune. there is another factor; painful emotions make us fall to pieces, while pleasant emotions bind us together. we can see why this is so when we remember that powerful emotions like fear and anger tend to dissociate all but themselves, to split up the mind into separate parts and to force out of consciousness everything but their own impulse. morton prince in his elaborate studies of the cases of multiple personality, miss beauchamp and b.c.a., found repeatedly that he had only to hypnotize the patient and replace painful, depressing complexes by healthy, happy ones to change her from a weak, worn-out person, complaining of fatigue, insomnia, and innumerable aches and pains, into a vigorous woman, for the time being completely well. on this point he says: exalting emotions have an intense synthesizing effect, while depressing emotions have a disintegrating effect. with the inrushing of depressive memories or ideas ... there is suddenly developed a condition of fatigue, ill-being and disintegration, followed after waking by a return or accentuation of all the neurasthenic symptoms. if on the other hand, exalting ideas and memories are introduced and brought into the limelight of attention, there is almost a magical reversal of processes. the patient feels strong and energetic, the neurasthenic symptoms disappear and he exhibits a capacity for sustained effort. he becomes re-vitalized, so to speak.[29] [footnote 29: prince: _psycho-therapeutics_, chap. i.] in cases like this the needed strength and energy are not lost; they are merely side-tracked, but the person feels as weak as though he were physically ill. bodily response to emotional states =secretions.= let us look more carefully into some of the physiological processes involved in emotional changes. among the most apparent of bodily responses are the various external secretions. tears, the secretion of the lachrymal glands in response to an emotion, are too common a phenomenon to arouse comment. it is common knowledge that clammy hands and a dry mouth betray emotion. every nursing mother knows that she dares not become too disturbed lest her milk should dry up or change in character. most people have experienced an increase in urine in times of excitement; recently physiologists have discovered the presence of sugar in the urine of students at the time of athletic contests and difficult examinations.[30] we have seen what an important role the various internal secretions, such as the adrenal and thyroid secretions play in fitting the body for flight and combat, and how large a part fear and anger have in their production. constant over-production of these secretions through chronic states of worry is responsible for many a distressing symptom. [footnote 30: cannon.] most graphic evidence of the disturbance of secretions by emotion is found in the response of the salivary and gastric glands to painful or pleasurable thinking. as these are the secretions which play the largest part in the digestive processes, they lead us naturally to our next heading. =digestion.= everybody knows that appetizing food makes the mouth water, but not everybody realizes that it makes the stomach water also. nor do we often realize the vital place that this watering has in taking care of our food. "well begun is half-done," is literally true of digestion. a good flow of saliva brings the food into contact with the taste-buds in the tongue. taste sends messages to the nerve-centers in the medulla oblongata; these centers in turn flash signals to the stomach glands, which immediately "get busy" preparing the all-important gastric juice. it takes about five minutes for this juice to be made ready, and so it happens that in five minutes after the first taste, or even in some cases after the first smell, the stomach is pouring forth its "appetite juice" which determines all the rest of the digestive process, in intestines as well as in stomach. experiments on dogs and cats by pawlow, cannon, and others have shown what fear and anger and even mildly unpleasant emotions do to the whole digestive process. cannon tells of a dog who produced 66.7 cubic centimeters of pure gastric juice in the twenty minutes following five minutes of sham feeding (feeding in which food is swallowed and then dropped out of an opening in the esophagus into a bucket instead of into the stomach). although there was no food in the stomach, the juice was produced by the enjoyment of the taste and the thought of it. on another day, after this dog had been infuriated by a cat, and then pacified, the sham feeding was given again. this time, although the dog ate eagerly, he produced only 9 cubic centimeters of gastric juice, and this rich in mucus. evidently a good appetite and attractively served food are not more important than a cheerful mind. spicy table talk, well mixed with laughter, is better than all the digestive tablets in the world. what is true of stomach secretions is equally true of stomach contractions. "the pleasurable taking of food" is a necessity if the required contractions of stomach and intestines are to go forward on schedule time. a little extra dose of adrenalin from a mild case of depression or worry is enough to stop all movements for many minutes. what a revelation on many a case of nervous dyspepsia! the person who dubbed it "emotional dyspepsia" had facts on his side. =circulation.= it is not the heart only that pumps the blood through the body. the tiny muscles of the smallest blood-vessels, by their elasticity are of the greatest importance in maintaining an even flow, and this is especially influenced by fear and depression. blushing, pallor, cold hands and feet, are circulatory disturbances based largely on emotions. better than a hot-water bottle or electric pads are courage and optimism. a patient of mine laughingly tells of an incident which she says happened a number of years ago, but which i have forgotten. she says that she asked me one night as she carried her hot-water bottle to bed, "doctor, what makes cold feet?" and that i lightly answered "cowardice!" whereupon she threw away her beloved water-bag and has never needed it since. there is a disturbance of the circulation which results in very marked swelling and redness of the affected part. this is known as angio-neurotic edema, or nervous swelling. i do not have to go farther than my own person for an example of this phenomenon. when i was a young woman i taught school and went home every day for luncheon. one day at luncheon, some one of the family criticized me severely. i went back to school very angry. before i entered the school-room, the principal handed me some books which she had ordered for me. they were not at all the books i wanted, and that upset me still more. as i went into the schoolroom, i found that my face was swollen until my eyes were almost shut; it was a bright red and covered with purplish blotches. my fingers were swollen so that i could not bend the joints in the slightest degree. it was a day or two before the disturbance disappeared, and the whole of it was the result of anger. we hear much to-day about high blood pressure. they say that a man is as old as his arteries, and now it is known that the health of the arteries depends largely on blood pressure. since this is a matter that can be definitely measured at any minute, we have an easy way of noting the remarkable effect of shifting emotions. sadler tells of an ex-convict with a blood pressure of 190 millimeters. it seems that he was worrying over possible rearrest. on being reassured on this point, his blood pressure began to drop within a few minutes, falling 20 mm. in three hours, and 35 mm. by the following day. =muscular tone.= a force that affects circulation, blood pressure, respiration, nutrition of cells, secretion, and digestion, can hardly fail to have a marked effect on the tone of the muscles, internal as well as external. when we remember that heart, stomach, and intestines are made of muscular tissue, to say nothing of the skeletal muscles, we begin to realize how important is muscular tone for bodily health. over and over again have i demonstrated that a courageous mind is the best tonic. perhaps an example from my "flat-footed" patients will be to the point. one woman, the young mother of a family, came to me for a nervous trouble. besides this, she had suffered for seven or eight years from severe pains in her feet and had been compelled to wear specially made shoes prescribed by a chicago orthopedist. the shoes, however, did not seem to lessen the pain. after an ordinary day's occupation, she could not even walk across the floor at dinner-time. a walk of two blocks would incapacitate her for many days. she was convinced that her feet could never be cured and came to me only on account of nervous trouble. on the day of her arrival she flung herself down on the couch, saying that she would like to go away from everybody, where the children would never bother her again. she was sure nobody loved her and she wanted to die. within three weeks, in ordinary shoes, this woman tramped nine miles up mount wilson and the next day tramped down again. her attitude had changed from that of irritable fretfulness to one of buoyant joy, and with the moral change had come new strength in the muscles. the death of her husband has since made it necessary for her to support the family, and she is now on her feet from eight to fourteen hours a day, a constant source of inspiration to all about her, and no more weary than the average person. flabbiness in the muscles often causes this trouble with the feet. "the arches of the foot are maintained by ligaments between the bones, supported by muscle tendons which prevent undue stretching of the ligaments and are a protection against flat-foot."[31] muscle tissue has an abundant blood supply, while ligaments have very little and soon lose their resiliency if unsupported. any lack of tone in the calf-muscles throws the weight on the less resistant ligaments and on the cartilages placed as cushions between the bony structures of the arch. this is what causes the pain.[32] [footnote 31: grey's anatomy--"the articulations."] [footnote 32: actual loss of the arch by downward displacement of the bones cannot be overcome by restoring muscle-tone. the majority of so-called cases of flatfoot are, however, in the stage amenable to psychic measures.] flat-footedness is only one result of weak muscles. eye-strain is another; ptosis, or falling of the organs, is another. in a majority of cases the best treatment for any of these troubles is an understanding attempt to go to the root of the matter by bracing up the whole mental tone. the most scientific oculists do not try to correct eye trouble due to muscular insufficiency by any special prisms or glasses. they know that the eyes will right themselves when the general health and the general spirits improve. i have found by repeated experience with nervous patients that it takes only a short time for people who have been unable to read for months or years to regain their old faculty. so remarkable is the power of mind. summary we have found that the gap between the body and the mind is not so wide as it seems, and that it is bridged by the subconscious mind, which is at once the master of the body and the servant of consciousness. in recording the physical effects of suggestion and emotion, we have not taken time to describe the galvanometers, the weighing-machines and all the other apparatus used in the various laboratory tests; but enough has been said to show that when doctors and psychologists speak of the effect of mind on body, they are dealing with definite facts and with laws capable of scientific proof. we have emphasized the fact that downcast and fearful moods have an immediate effect on the body; but after all, most people know this already. what they do not know is the real cause of the mood. when a nervous person finds out why he worries, he is well on the way toward recovery. an understanding of the cause is among the most vital discoveries of modern science. the discussion, so far, has merely prepared us to plunge into the heart of the question: what is it that in the last analysis makes a person nervous, and how may he find his way out? this question the next two chapters will try to answer. chapter vii _in which we go to the root of the matter_ the real trouble pioneers =following the gleam.= kipling's elephant-child with the "'satiable curiosity" finally asked a question which seemed simple enough but which sent him on a long journey into unknown parts. in the same way man's modest and simple question, "what makes people nervous?" has sent him far-adventuring to find the answer. for centuries he has followed false trails, ending in blind alleys, and only lately does he seem to have found the road that shall lead him to his journey's end. we may be thankful that we are following a band of pioneers whose fearless courage and passion for truth would not let them turn back even when the trail led through fields hitherto forbidden. the leader of this band of pioneers was a young doctor named freud. the search for truth =early beginnings.= in 1882, when freud was the assistant to dr. breuer of vienna, there was brought to them for treatment a young woman afflicted with various hysterical pains and paralyses. this young woman's case marked an epoch in medical history; for out of the effort to cure her came some surprising discoveries of great significance to the open-minded young student. it was found that each of this girl's symptoms was related to some forgotten experience, and that in every case the forgetting seemed to be the result of the painfulness of the experience. in other words, the symptoms were not visitations from without, but expressions from within; they were a part of the mental life of the patient; they had a history and a meaning, and the meaning seemed in some way to be connected with the patient's previous attitude of mind which made the experience too painful to be tolerated in consciousness. these previous ideas were largely subconscious and had been acquired during early childhood. when by means of hypnosis a great mass of forgotten material was brought to the surface and later made plain to her consciousness, the symptoms disappeared as if by magic. =a startling discovery.= for a time breuer and freud worked together, finding that their investigations with other patients served to corroborate their former conclusions. when it became apparent that in every case the painful experience bore some relation to the love-life of the patient, both doctors were startled. along with most of the rest of the world, they had been taught to look askance at the reproductive instinct and to shrink from realizing the vital place which sex holds in human life. breuer dropped the work, and after an interval freud went on alone. he was resolved to know the truth, and to tell what he saw. when he reported to the world that out of all his hundreds of patients, he had been unable, after the most careful analysis, to find one whose illness did not grow from some lack of adjustment of the sex-life, he was met by a storm of protest from all quarters. no amount of evidence seemed to make any difference. people were determined that no such libel should be heaped on human nature. sex-urge was not respectable and nervous people were to be respected. despite public disapproval, the scorn of other scientists, and the resistance of his own inner prejudices, freud kept on. he was forced to acknowledge the validity of the facts which invariably presented themselves to view. like luther under equal duress, he cried: "here i stand. i can do no other." =freudian principles.= gradually, as he worked, he gathered together a number of outstanding facts about man's mental life and about the psycho-neuroses. these facts he formulated into certain principles, which may be summed up in the following way. 1 there is no _chance_ in mental life; every mental phenomenon--hence every nervous phenomenon--has a cause and meaning. 2 infantile mental life is of tremendous importance in the direction of adult processes. 3 much of what is called forgetting is rather a repression into the subconscious, of impulses which were painful to the personality as a whole. 4 mental processes are dynamic, insisting on discharge, either in reality or in phantasy. 5 an emotion may become detached from the idea to which it belongs and be displaced on other ideas. 6 sex-interests dominate much of the mental life where their influence is unrecognized. the disturbance in a psycho-neurosis is always in this domain of sex-life. "in a normal sexual life, no neurosis." if a shock is the precipitating cause of the trouble, it is only because the ground was already prepared by the sex-disturbance. freud was perhaps unfortunate in his choice of the word "sex," which has so many evil connotations; but as he found no other word to cover the field, he chose the old one and stretched its meaning to include all the psychic and physical phenomena which spring directly and indirectly from the great processes of reproduction and parental care, and which ultimately include all and more than our word "love."[33] [footnote 33: freud and his followers have always said that they saw no theoretical reason why any other repressed instinct should not form the basis of a neurosis, but that, as a matter of fact, they never had found this to be the case, probably because no other instinct comes into such bitter and persistent conflict with the dictates of society. now, however, the great war seems to have changed conditions. under the strain and danger of life at the front there has developed a kind of nervous breakdown called shellshock or war-neurosis, which seems in some cases to be based not on the repression of the instinct of race-preservation but on the unusual necessity for repression of the instinct of self-preservation. army surgeons report that wounded men almost never suffer from shell-shock. the wound is enough to secure the unconsciously desired removal to the rear. but in the absence of wounds, a desire for safety may at the same time be so intense and so severely repressed that it seizes upon the neurosis as the only possible means of escape from the unbearable situation. in time of peace, however, the instinct of reproduction seems to be the only impulse which is severely enough repressed to be responsible for a nervous breakdown.] =later developments.= little by little, the scientific world came to see that this wild theorizer had facts on his side; that not only had he formulated a theory, but he had discovered a cure, and that he was able to free people from obsessions, fears, and physical symptoms before which other methods were powerless. one by one the open-minded men of science were converted by the overpowering logic of the evidence, until to-day we find not only a "freudian school," counting among its members many of the eminent scientists of the day, but we find in medical schools and universities courses based on freudian principles, with text-books by acknowledged authorities in medicine and psychology. we find magazines devoted entirely to psycho-analytic subjects,[34] besides articles in medical journals and even numerous articles in popular magazines. not only is the treatment of nervous disorders revolutionized by these principles but floods of light are thrown on such widely different fields of study as ancient myths and folk lore, the theory of wit, methods of child training, and the little slips of the tongue and everyday "breaks" that have until recently been considered the meaningless results of chance. [footnote 34: _the psychoanalytic review_ and the _international journal of psychoanalysis._] =a searching question.= we find, then, that when we ask, "what makes people nervous?" we are really asking: "what is man like, inside and out, up and down? what makes him think, feel, and act as he does every hour of every day?" we are asking for the source of human motives, the science of human behavior, the charting of the human mind. it is hard to-day to understand how so much reproach and ridicule could have been aroused by the statement that the ultimate cause of nervousness is a disturbance of the sex-life. there has already been a change in the public attitude toward things sexual. training-courses for mothers and teachers, elementary teaching in the schools, lectures and magazine articles have done much to show the fallacy of our old hypersensitive attitude. since the war, some of us know, too, with what success the army has used the freudian principles in treating war-neurosis, which was mistakenly called shell-shock by the first observers. we know, too, more about the constitution of man's mind than the public knew ten years ago. when we remember the insistent character of the instincts and the repressive method used by society in restraining the most obstreperous impulse, when we remember the pain of such conflict and the depressing physical effects of painful emotions, we cannot wonder that this most sharply repressed instinct should cause mental and physical trouble. =what about sublimation?= on the other hand, it has been stated in chapter iv that although this universal urge cannot be repressed, it can be sublimated or diverted to useful ends which bring happiness, not disaster, to the individual. we have a right, then, to ask why this happy issue is not always attained, why sublimation ever fails. if a psycho-neurosis is caused by a failure of an insistent instinct to find adequate expression, by a blocking of the libido or the love-force, what are the conditions which bring about this blocking? the sex-instinct of every respectable person is subject to restraint. some people are able to adjust themselves; why not all? the question, "what makes people nervous?" then turns out to mean: what keeps people from a satisfactory outlet for their love-instincts? what is it that holds them back from satisfaction in direct expression, and prevents indirect outlet in sublimation? whatever does this must be the real cause of "nerves." the causes of "nerves" =plural, not singular.= the first thing to learn about the cause is that it is not a cause at all, but several causes. we are so well made that it takes a combination of circumstances to upset our equilibrium. in other words, a neurosis must be "over-determined." heredity, faulty education, emotional shock, physical fatigue, have each at various times been blamed for a breakdown. as a matter of fact, it seems to take a number of ingredients to make a neurosis,--a little unstable inheritance plus a considerable amount of faulty upbringing, plus a later series of emotional experiences bearing just the right relationship to the earlier factors. heredity, childhood reactions, and later experiences, are the three legs on which a neurosis usually stands. an occasional breakdown seems to stand on the single leg of childhood experiences but in the majority of cases each of the three factors contributes its quota to the final disaster. =born or made?= it used to be thought that neurotics, like poets, were born, not made. heredity was considered wholly responsible, and there seemed very little to do about it. but to-day the emphasis on heredity is steadily giving way to stress on early environment. there are, no doubt, such factors as a certain innate sensitiveness, a natural suggestibility, an intensity of emotion, a little tendency to nervous instability, which predispose a person to nerves, but unless the inborn tendency is reinforced by the reactions and training of early childhood, it is likely to die a natural death. childhood experiences =early reactions.= freud found that a neurotic is made before he is six years old. when by repeated explorations into the minds of his patients, he made this important discovery, he at first believed that the disturbing factor was always some single emotional experience or shock in childhood,--usually of a sexual nature. but freud and later investigators have since found that the trouble is not so often a single experience as a long series of exaggerated emotional reactions, a too intense emotional life, a precocity in feeling tending toward fixation of childhood habits, which are thus carried over into adult life. =fixation of habits.= fixation is the word that expresses all this,--fixation of childish habits. a neurotic is a person who made such strong habits in childhood that he cannot abandon them in maturity. he is too much ruled by the past. his unconscious emotional thought-habits are the complexes which were made in childhood and therefore lack the power of adaptation to mature life. we saw in chapter iv that nature takes great pains to develop in the child the psychic and physical trends which he will need later on in his mature love-life, and that this training is accomplished in a number of well-defined periods which lead from one to the other. if, however, the child reacts too intensely, lingers too long in any one of these phases, he lays for himself action lines of least resistance which he may never leave or to which he may return during the strain and stress of adult life. in either case, the neurotic is a grown-up child. he may be a very learned, very charming person, but he is nevertheless dragging behind him a part of his childhood which he should have outgrown long ago. part of him is suffering from an arrest of development,--not a leg or an arm but an impulse. =precocious emotions.= the habits which tend to become fixed too soon seem to be of four kinds; the habit of loving, the habit of rebelling, the habit of repressing normal instincts, and the habit of dreaming. in each case it is the excess of feeling which causes the trouble,--too much love, too much hate, too much disgust, or too much pleasure in imagination. exaggeration is always a danger-signal. an overdeveloped child is likely to be an underdeveloped man. especially in the emotions is precocity to be deplored. a premature alphabet or multiplication table is not nearly so serious as premature intensity of feeling, nor so likely to lead later to trouble. of course fixation in these emotional habits does not always lead to a serious breakdown. if the fixation is not too extreme, and if later events do not happen to accentuate the trouble, the arrest of development may merely show itself in certain weaknesses of character or in isolated symptoms without developing a real neurosis. let us examine each of these arrested habits and the excess emotion which sets the mold before it is ready for maturity. =too much self-love.= in the chapter on the reproductive instinct, we found that the natural way to learn to love is by successively loving oneself, one's parents and family, one's fellows, and one's mate. if the love-force gets too much pleasure in any one of these phases, it finds it hard to give up its old love and to pass on to the next phase. thus some children take too much pleasure in their own bodies or, a little later, in their own personalities. if they are too much interested in their own physical sensations and the pleasure they get by stimulating certain zones of the body, then in later life they cannot free themselves from the desire for this kind of satisfaction. try as they may, they cannot be satisfied with normal adult relations, but sink back into some form of so-called sex-perversion. perhaps it is another phase of self-love which holds the child too much. if, like narcissus, he becomes too fond of looking at himself, is too eager to show off, too desirous of winning praise, then forever after he is likely to be self-conscious, self-centered, thinking always of the impression he is making, unable ever to be at leisure from himself. he is fixed in the narcissistic stage of his life, and is unadapted to the world of social relations. =too much family-love.= we have already spoken of the danger of fixation in the second period, that of object-love--the period of family relationships. the danger is here again one of degree and may be avoided by a little knowledge and self-control on the part of the parents. the little girl who is permitted to lavish too much love on her father, who does not see anybody else, who cannot learn to like the boys is a misfit. the wise mother will see that her love for her boy does not express itself too much by means of hugs and kisses. the mother who shows very plainly that she loves her little boy better than she loves her husband and the mother who boasts that her adolescent boy tells her all his secrets and takes her out in preference to any girl--that deluded mother is trying to take something that is not hers, and is thereby courting trouble. when her son grows up, he may not know why, but no girl will suit him, and he will either remain a bachelor or marry some older woman who reminds him subconsciously of his mother. his love-requirements will be too strict; he will be forever trying either in phantasy or in real life to duplicate his earlier love-experiences. this, of course, cannot satisfy the demands of a mature man. he will be torn between conflicting desires, unhappy without knowing why, unable either to remain a child or to become a man, and impelled to gain self-expression in indirect and unsatisfactory ways. since it is not possible in this space to recite specific cases which show how often a nervous trouble points back to the father-mother complex,[35] it may help to cite the opinions of a few of our best authorities. freud says of the family complex, "this is the root complex of the neurosis." jelliffe: "it is the foot-rule of measurement of success in life": by which he means that just so far as we are able at the right time to free ourselves from dependence on parents are we able to adjust ourselves to the world at large. pfister: "the attitude toward parents very often determines for a life-time the attitude toward people in general and toward life itself." hinkle: "the entire direction of lives is determined by parental relationships." [footnote 35: this is technically known as the oedipus complex.] =too much hate.= besides loving too hard, there is the danger of hating too hard. if it sounds strange to talk of the hatreds of childhood, we must remember that we are thinking of real life as it is when the conventions of adult life are removed and the subconscious gives up its secrets. several references have been made to the jealousy of the small child when he has to share his love with the parent of the same sex. for every little boy the father gets in the way. for every little girl the mother gets in the way. at one time or other there is likely to be a period when this is resented with all the violence of a child's emotions. it is likely to be very soon repressed and succeeded by a real affection which lasts through life. but underneath, unmodified by time, there may exist simultaneously the old childish image and the old unconscious reaction to it, unconscious but still active in indirect ways. jealousy is very often united with the natural rebellion of a child against authority. the rebellion may, of course, be directed against either parent who is final in authority in the home. in most cases this is the father. as the impulse of self-assertion is usually stronger in boys than in girls, and as the boy's impulse in this direction is reinforced by any existing jealousy toward his father, we find a strong spirit of rebellion more often playing a subconscious part in the life of men than of women. the novelist's favorite theme of the conflict between the young man and "the old man" represents the conscious, unrepressed complex. more often, however, there is true affection for the father, while the rebellion which really belongs to the childish father-image is displaced or transferred to other symbols of authority,--the state, the law, the king, the school, the teacher, the church, or perhaps to religion and authority in general. anarchists and atheists naturally rationalize their reasons for dissent, but, for all that, they are not so much intellectual pioneers as rebellious little boys who have forgotten to grow up. =liking to be "bossed."= there is a worse danger, however, than too much rebellion, and that is too little rebellion. sometimes this yielding spirit is the result of an overdose of negative self-feeling and an under-dose of positive self-feeling; but sometimes it is over-compensation for the repressed spirit of rebellion which the child considers wicked. consciously he becomes over-meek, because he has to summon all his powers to fight his subconscious insurrection. whether he be meek by nature or by training, he is likely to be a failure. everybody knows that the child who is too good never amounts to anything. he who has never disobeyed is a weakling. naturally resenting all authority, the normal individual, if he be well trained, soon learns that some authority is necessary. he rebels, but he learns to acquiesce, to a certain degree. if he acquiesces too easily, represses too severely his rebellious spirit, swings to the other extreme of wanting to be "bossed," he is very likely to end as a nervous invalid, unfitted for the battles of life. the neurotic in the majority of cases likes authority, clings to it too long, wants the teacher to tell him what to do, wants the doctor to order him around, is generally over-conscientious, and afraid he will offend the "boss" or some one else who reminds him of the father-image. all this carries a warning to parents who cannot manage their children without dominating their lives, even when the domination is a kindly one. perhaps the modern child is in more danger of being spoiled than bullied, but analysis of nervous patients shows that both kinds of danger still exist. =too much disgust.= the third form of excessive emotion is disgust. the love-force, besides being blocked by a fixation of childish love and of childish reactions toward authority, is very often kept from free mature self-expression by a perpetuation of a childish reaction against sex. we hardly need dwell longer on the folly of teaching children to be ashamed of so inevitable a part of their own nature. disgust is a very strong emotion, and when it is turned against a part of ourselves, united with that other strong impulse of self-regard and incorporated into the conscience, it makes a chinese wall of exclusion against the baffled, misunderstood reproductive instinct, which is thrust aside as alien. =restraint versus denial.= repression is not merely restraint. it is restraint plus denial. to the clamoring instinct we say not merely, "no, you _may_ not," but "no, you _are_ not. you do not exist. nothing like you could belong to me." the woman with nausea (chapter v) did not say to herself: "you are a normal, healthy woman, possessed of a normal woman's desires. but wait a while until the proper time comes." controlled by an immature feeling of disgust, she had said: "i never thought it. it cannot be." the difference is just this. when an ungratifiable desire is honestly faced and squarely answered, it is modified by other desires, chooses another way of discharge, and ceases to be desire. when a desire is repressed, it is still desire, unsatisfied, insistent, unmodifiable by mature points of view, untouched by time, automatic, and capable of almost any subterfuge in order to get satisfaction. a repressed desire is buried, shut away from the disintegrating effects of sunlight and air. while the rest of the personality is constantly changing under the influence of new ideas, the buried complex lives on in its immaturity, absolutely untouched by time. =childish birth-theories.= when a child's questions about where babies come from are met by evasions, he is forced to manufacture his own theories. his elders would laugh if they knew some of these theories, but they would not laugh if they knew how often the childish ideas, wide of the truth, furnish the material for future neuroses. frink tells the story of a young woman who had a compulsion for taking drugs. although not a drug-fiend in the usual sense, she was constantly impelled to take any kind of drug she could obtain. it was finally revealed that during her childhood she had tried hard to discover how babies were made, and had at last concluded that they grew in the mother as a result of some medicine furnished by the doctor. the idea had long been forgotten, only to reappear as a compulsion. the natural desire for a child was strong in her, but was repressed as unholy in an unmarried woman. the associated childish idea of drug-taking was not repellent to her moral sense and was used as a substitute for the real desire to bear a child. many of my patients have suffered from the effect of some such birth-theories. one young girl, twenty years old, was greatly afflicted with myso-phobia, or the fear of contamination. she spent most of her time in washing her hands and keeping her hands and clothing free from contamination by contact with innumerable harmless objects. when cleaning her shoes on the grass, she would kneel so that the hem of her skirt would touch the grass, lest some dust should fly up under her clothes. after eating luncheon in the park with a girl who had tuberculosis, she said that she was not afraid of tuberculosis in the lungs, but asked if something like tuberculosis might not get in and begin to grow somewhere else. her life was full to overflowing of such compulsive fears. as opportunity offered itself from day to day, i would catch her compulsive ideas in the very act of expressing themselves, and would pin her down as to the association and the source of her fear, always taking care not to make suggestions or ask leading questions. she was finally convinced out of her own mouth that her real fear was the idea of something getting into her body and growing there. then she told how she had questioned her mother about the reproductive life and had been put off with signs of embarrassment. for a long time she had been afraid to walk or talk with a boy, because, not knowing how conception might occur, she feared grave consequences. very soon after the beginning of her conversations with me, the girl realized that her fear was really a disguised desire that something might be planted within and grow. with her new understanding of herself, her compulsions promptly slipped away. she began to eat and sleep, and to live a happy, natural life. =chronic repression.= it takes first-hand acquaintance with nervous patients to realize how common are stories like these. unnecessary repressions based on false training are the cause of many a physical symptom and mental distress which a little parental frankness might have forestalled.[36] [footnote 36: parents who are eager to handle this subject in the right way are often sincerely puzzled as to how to go about it. no matter how complete their education, it is very likely to fail them at this critical point. for the benefit of such parents, let it be said with all possible emphasis that the first and most important step must be a change in their own mental attitude. if there is left within them the shadow of embarrassment on the subject of sex, their children will not fail to sense the situation at once. a feeling of hesitation or a tendency to apologize for nature makes a far deeper impression on the child-mind than do the most beautiful of half-believed words on the subject. and this impression, subtle and elusive as it may seem, is a real and vital experience which is quite likely to color the whole of the child's life. if you would give your children a fair start, you must first get rid of your own inner resistances. after that, all will be clear sailing. in the second place, take the earliest opportunity to bring up the subject in a natural way. a young father told me recently that his little daughter had asked her mother why she didn't have any lap any more. "and of course your wife took that chance to tell her about the baby that is coming," i said. "oh, no," he answered, "she did nothing of the kind. mary is far too young to know about such things." there are always chances if we are on the look out for them--and the earlier the better. it has been noticed that children are never repelled by the idea of any natural process unless the new idea runs counter to some notion which has already been formed. the wise parent is the one who gets in the right impression before some other child has had a chance to plant the wrong one. then, too, we elders are judged quite as much by what we do not say as by what we do. happy is the child who is not left to draw his own conclusions from the silence and evasiveness of his parents. the sex-instruction which children are getting in the schools is often good, but it usually comes too late--the damage is always done before the sixth year. when it comes to the exact words in which to explain the phenomena of generation and birth each parent must naturally find his own way. the main point is that we must tell the truth and not try to improve on nature. if we say that the baby grows under the mother's heart and later the child learns that this is not true, he inevitably gets the idea that there is something not nice about the part of the body in which the baby does grow. what could be wrong with the simple truth that the father plants a tiny seed in the mother's body and that this seed joins with another little seed already there and grows until it is a real baby ready to come into the world? the question as to how the father plants the seed need cause no alarm. if brothers and sisters are brought up together with no artificial sense of false modesty, they very early learn the difference between the male and the female body. it is simple enough to tell the little child the function of the male structure. and it is easy to explain that the seeds do not grow until the little boy and girl have grown to be man and woman and that the way to be well and to have fine strong children is to leave the generative organs alone until that time. a sense of the dignity and high purpose of these organs is far more likely to prevent perversions--to say nothing of nervousness--than is an attitude of taboo and silence.] a certain amount of repression is inevitable and useful, but a neurotic is merely an exaggerated represser. he represses so much of himself that it will not stay down.[37] he builds up a permanent resistance which automatically acts as a dam to his normal sex instinct and forces it into undesirable outlets. [footnote 37: "a neurosis is a partial failure of repression." frink: _morbid fears and compulsions_.] a resistance is a chronic repression, repression that has become fixed and subconscious, a habit that has lost its flexibility and outlives its usefulness. it is a fixation of repression, and is built out of an over-strong complex or emotional thought habit, acquired during childhood, incorporated into the conscience and carried over into maturity, where it warps judgment and interferes with normal development because it is fundamentally untrue and at variance with the laws of nature. =too much day-dreaming.= the fourth habit which holds back the adult from maturity and predisposes toward "nerves" is the habit of imagination. it need hardly be said that a certain kind of imagination is a good thing and one of man's greatest assets. but the essence of day-dreaming is the exact opposite; it is the desire to see things as they are not, but as we should like them to be,--not in order that we may bring them to pass, but for the mere pleasure of dreaming. instead of turning a microscope or a telescope on the world of reality, as positive imagination does, this negative variety refuses even to look with the naked eye. to dream is easier than to do; to build up phantasies is easier than to build up a reputation or a fortune; to think a forbidden pleasure is easier than to sublimate. "pleasure-thinking" is not only easier than "reality-thinking,"--it is the _older_ way. children gratify many of their desires simply by imagining them gratified. much of the difficulty of later life might be avoided if the little child could be taught to work for the accomplishment of his pleasures rather than to dream of them. the normal child gradually abandons this "pleasure-thinking" for the more purposeful thinking of the actual world, but the child who loiters too long in the realm of fancy may ever after find it hard to keep away from its borders. his natural interest in sex, if artificially repressed, is especially prone to satisfy itself by way of phantasy. =turning back to phantasy.= in later life, when the love-force for one reason or another becomes too strong to be handled either directly or indirectly in the real world, there comes the almost irresistible impulse to regress to the infantile way and to find expression by means of phantasy. after long experience freud concluded that phantasy lies at the root of every neurosis. jung says that a sex-phantasy is always at least one determiner of a nervous illness, and jelliffe writes that the essence of the neurosis is a special activity of the imagination. such a statement need not shock the most sensitive conscience. the very fact that a neurosis breaks out is proof that the phantasies are repellent to the owners of them and are thrust down into the subconscious as unworthy. in fact, every neurosis is witness to the strength of the human conscience. no phantasy could cause illness. it is the phantasy plus the repression of it that makes the trouble, or rather it is the conflict between the forces back of the phantasy and the repression. the neurosis, then, turns out to be a "flight from the real," the result of a desire to run away from a difficulty. when a problem presses or a disagreeable situation is to be faced, it is easier to give up and fall ill than to see the thing through to the end. here again, we find that nervousness is a regression to the irresponsible reactions of childhood. =maturity versus immaturity.= we have been thinking of the main causes of "nerves" and have found them to be infantile habits of loving, rebelling, repressing, and dreaming. we have tried to show that these habits are able to cause trouble because of their bearing on that inevitable conflict between the ancient urge of the reproductive instinct and the later ideals which society has acquired. if this conflict be met in the light of the present, free from the backward pull, of outgrown habits, an adjustment is possible which satisfies both the individual and society. we call this adjustment sublimation. this is rather a synthesis than a compromise, a union of the opposing forces, a happy utilization of energy by displacement on more useful ideas. but if the conflict has to be met with the mind hampered by immature thinking and immature feeling; if the demands of the here-and-now are met as if it were long ago; if unhealthy and untrue complexes, old loves and hates complicate the situation; if to the necessary conflict is added an unnecessary one; then something else happens. compromise of some kind must be made, but instead of a happy union of the two forces a poor compromise is effected, gaining a partial satisfaction for both sides, but a real one for neither. the neurosis is this compromise. later experiences =the last straw.= the precipitating cause may be one of a number of things. it may be entirely within, or it may be external. perhaps it is only a quickening of the maturing instincts at the time of adolescence, making the love-force too strong to be held by the old repressions. perhaps the husband, wife, or lover dies, or the life-work is taken away, depriving the vital energy of its usual outlets. perhaps the trigger is pulled by an emotional shock which bears a faint resemblance to old emotional experiences, and which stimulates both the repressing and repressed trends and makes the person at the same time say both "yes," and "no."[38] perhaps physical fatigue lets down the mental and moral tension and makes the conflict too strong to be controlled. perhaps an external problem presses and arouses the old habit of fleeing from disagreeable reality. any or all these factors may cooperate, but not one of them is anything more than a last straw on an overburdened back. no calamity, deprivation, fatigue, or emotion has been able to bring about a neurosis unless the ground was prepared for it by the earlier reactions of childhood. [footnote 38: "the external world can only cause repression when there was already present beforehand a strong initial tension reaching back even to childhood."--pfister: _psychoanalytic method_, p. 94.] the breakdown itself ="two persons under one hat."= we can understand now why a neurotic can be described in so many ways. we often hear him called an especially moral, especially ethical person, with a very active conscience; an intensely social being, unable to be satisfied with anything but a social standard; a person with "finer intellectual insight and greater sensitiveness than the rest of mankind." at the same time we are told that a neurosis is a partial triumph of anti-social, non-moral factors, and that it is a cowardly flight from reality; we hear a nervous invalid called selfish, unsocial, shut in, primitive, childish, self-deceived. both these descriptions are true to life. a neurosis is an ethical struggle between these two sets of forces. if the lower set had triumphed, the man would have been merely weak; if the higher set had been victorious, he would have been strong. as it is, he is neither one nor the other,--only nervous. the neurosis is the only solution of the struggle which he is able to find, and serves the purpose of a sort of armed armistice between the two camps. serving a purpose if a neurosis is a compromise, if it is the easiest way out, if it serves a purpose, it must be that the individual himself has a hand in shaping that purpose. can it be that a breakdown which seems such an unmitigated disaster is really welcomed by a part of our own selves? nothing is more intensely resented by the nervous invalid than the accusation that he likes his symptoms,--and no wonder. the conscious part of him hates the pain, the inconvenience, and the disability with a real hatred. it is not pleasant to be ill. and yet, as it turns out, it is pleasanter to be ill than it is to bear the tension of unsatisfied desire or to be undeceived about oneself. every symptom is a means of expression for repressed and forgotten impulses and is a relief to the personality. it tends to the preservation of the individual, rather than to his destruction. the nervous invalid is not short-lived, but his family may be! it has been said that a neurosis is not so much a disease as a dilemma. rather might it be said that the neurosis is a way out of the dilemma. it is a harbor after a stormy sea, not always a quiet harbor, but at least a usable one. unpleasant as it is, every nervous symptom is a form of compensation which has been deliberately though unconsciously chosen by its owner. =rationalizing our distress.= among other things, a nervous symptom furnishes a seemingly reasonable excuse for the sense of distress which is behind every breakdown. something troubles us. we are not willing to acknowledge what it is. on the other hand, we must appear reasonable to ourselves, so we manufacture a reason. perhaps at the time when the person first feels distress, he is on a railroad train. so he says to himself, "it is the train. i must not go near the railway"; and he develops a phobia for cars. perhaps at the onset of the fear he happens to have a slight pain in the arm. he makes use of the pain to explain his distress. he thinks about it and holds on to it. it serves a purpose, and is on the whole less painful than the feeling of unexplained impending disaster which is attached to no particular idea. perhaps he happens to be tired when the conflict first gets beyond control. so he seizes the idea of fatigue to explain his illness. he develops chronic fatigue and talks proudly of overwork. in every case the symptom serves a real purpose, and is, despite its discomfort, a relief to the distressed personality. a neurosis is a subconscious effort at adjustment. like a physical symptom, it is nature's way of trying to cure herself. it is an attempt to get equilibrium, but it is an awkward attempt and hardly the kind that we would choose when we see what we are doing. =securing an audience.= besides furnishing relief from too intense strain, a nervous breakdown brings secondary advantages that are at most only dimly recognized by the individual. one of the most intense cravings of the primitive part of the subconscious is for an audience; a nervous symptom always secures that audience. the invalid is the object of the solicitous care of the family, friends, physician, and specialist. pomp and ceremony, so dear to the child-mind, make their appeal to the dissociated part of the personality. the repressed instincts, hungry for love and attention, delight in the petting and special care which an illness is sure to bring. secretly and unconsciously, the neurotic takes a certain pleasure in all the various changes that are made for his benefit,--the dismantling of striking clocks, the muffling of household noises, the banishing of crowing roosters, and the changes in menu which must be carefully planned for his stomach. this characteristic of finding pleasure in personal ministrations is plainly a regression to the infantile phase of life. the baby demands and obtains the center of the stage. later he has to learn to give it up, but the neurotic gets the center again and is often very loth to leave it for a more inconspicuous place. =capitalizing an illness.= then, too, a neurosis provides a way of escape from all sorts of disagreeable duties. it can be capitalized in innumerable ways,--ways that would horrify the invalid if he realized the truth. much of the resentment manifested against the suggestion that the neurosis is psychic in origin is simply a resistance against giving up the unconsciously enjoyed advantages of the illness. an honest desire to get well is a long step toward cure. the purposive character of a nervous illness is well illustrated by two cases reported by thaddeus hoyt ames.[39] a young woman, the drudge of the family, suddenly became hysterically blind, that is, she became blind despite the fact that her eyes and optic nerves proved to be unimpaired. she remained blind until it was proved to her that a part of her welcomed the blindness and had really produced it for the purpose of getting away from the monotony of her unappreciated life at home. she naturally resented the charge but finally accepted it and "turned on" her eyesight in an instant. the other patient, a man, became blind in order to avoid seeing his wife who had turned out to be not at all what he had hoped. when he realized what he was doing, he decided that there might be better ways of adjusting himself to his wife. he then switched on his seeing power, which had never been really lost, but only disconnected and dissociated from the rest of his mind. [footnote 39: thaddeus hoyt ames: _archives of ophthalmology_, vol. xliii, no. 4, 1914.] that the conscious mind has no part in the subterfuge is shown by the fact that both patients gave up their artificial haven as soon as they saw how they had been fooling themselves. the fact remains that every neurosis is the fulfilment of a wish,--a distorted, unrecognized, unsatisfactory fulfilment to be sure, but still an effort to satisfy desire. as frink remarks, "a neurosis is a kind of behaviour." we always choose the conduct we like. it is a matter of choice. does not this answer our question as to why some people always take unhealthy suggestions? if we take the bad one, it is because it serves the need of a part of our being. sign language =talking in symbols.= we have several times suggested that a nervous symptom is a disguised, indirect expression of subconscious impulses. it is the completeness of the disguise which makes it so hard for us to realize its true meaning. it takes a stretch of the imagination to believe that a pain in the body can mean a pain in the soul, or that a fear of contamination can signify a desire to bear a child. but in all this we must not forget the primitive, childlike nature of the instinctive life. the savage and the child do not think as civilized man thinks. savage or child thinks in pictures; he acts his feelings; he groups things according to superficial resemblances, he expresses an idea by its opposite; he talks in symbols. we still use these devices in poetic speech and in everyday thought. a wedding-ring stands for the marriage bond; the flag for a nation; a greyhound for fleetness; a wild beast for ferocity; sunrise for youth; and sunset for old age. "the essence of language consists in the statement of resemblance. the expression of human thought is an expression of association."[40] [footnote 40: trigant burrow: _journal of american medical association_, vol. lxvi, no. ii, 1916.] the association may be so accidental and superficial as to seem absurd to another person, or it may be so fundamental as to express the universal thought of man from the beginning of time. many of the signs and symbols which crop out in neurotic symptoms and in normal dreams are the same as those which appear in myths, fairy tales and folk-lore and in the art of the earlier races. =a secret code.= when the denied instincts of a man's repressed life insist on expression, and when the shocked proprieties of his repressing life demand conformity to social standards, the subconscious, held back from free speech, strikes a compromise by making use of figurative language. as trigant burrow says, if the moral repugnance is very strong, the disguise must be more elaborate, the symbols more far-fetched. the symbols of nervous symptoms and of dreams are a "secret code," understood by the sender but meaningless to the censoring conscience, which passes them as harmless. =the right kind of symbolism.= sublimation itself is merely a symbolic expression of basic impulses. it follows the line of our make-up, which naturally and fundamentally is wont to let one thing stand for another and to express itself in indirect ways. sublimation says: "if i cannot recreate myself in the person of a child, i will recreate myself in making a bridge, or a picture, or a social settlement,--or a pudding." it says: "if i cannot have my own child to love, i will adopt an orphan-asylum, or i will work for a child-labor law." it merely lets one thing stand for another and transfers all the passions that belong to the one on to the other, which is the same thing as saying that it gives vent to its original desire by means of symbolic expression. =the wrong kind of symbolism.= a nervous disorder is an unfortunate choice of symbols. instead of spiritualizing an innate impulse, it merely disguises it. the disguise takes a number of forms. one of the commonest ways is to act out in the body what is taking place in the soul. the woman with nausea converted her moral disgust into a physical nausea, which expressed her distress while it hid its meaning. the girl who was tired of seeing her work, and the man who wanted to avoid seeing his wife chose a way out which physically symbolized their real desire. a dentist once came to me with a paralyzed right arm. he had given up his office and believed that he would never work again. it turned out that his only son had just died and that he was dramatizing his soul-pain by means of his body. his subconscious mind was saying, "my good right arm is gone," and saying it in its own way. within a week the arm was playing tennis, and ever since it has been busy filling teeth. there were, of course, other factors leading up to the trouble, but the factor which determined its form was the sense of loss which acted itself out through the body. sometimes, as we have seen, the disguise takes another form. instead of conversion into a physical symptom, it lets one idea stand for another and displaces the impulse or the emotion to the substitute idea. the girl with the impulse to take drugs fooled her conscience by letting the drug-taking idea stand for the idea of conception. the girl with the fear of contamination carried the disguise still farther by changing the desire into fear,--a very common subterfuge. =the case of mrs. y.= there came to me a short time ago a little woman whose face showed intense fright. for several months she had spent much of the time walking the floor and wringing her hands in an agony of terror. in the night she would waken from her sleep, shaking with fear; soon she would be retching and vomiting, although she herself recognized the fact that there was nothing the matter with her stomach. part of the time her fear was a general terror of some unknown thing, and part of the time it was a specialized fear of great intensity. she was afraid she would choke her son, to whom she was passionately devoted. during the course of the treatment, which followed the lines of psycho-analysis to be described in the next chapter, i found that this fear had arisen one evening when she was lying reading by the side of her sleeping child. suddenly, without warning, she had a sort of mental picture of her own hands reaching out and choking the boy. naturally she was terrified. she jumped out of bed, decided that she was losing her mind and went into a hysterical state which her husband had great trouble in dispelling. after that she was afraid to be left alone with her children lest she should kill them. during the analysis it was discovered that what she had been reading on that first night was the thirteenth verse of the ninety-first psalm. "thou shalt tread upon the lion and the adder. the young lion and the dragon thou shalt trample under foot." to her the adder meant the snake, the tempter in the garden of eden, and hence sex. what she wanted to choke was her own insistent sex urge of which the child was the symbol and the result. on later occasions she had the same sort of hallucinations in connection with another child and on sight of a brutish kind of man who symbolized to the subconscious mind the sex-urge, of which she was afraid. not so much by what her mother had said as by what she had avoided saying, and by her expression whenever the subject was mentioned, had she given her little daughter a fundamentally wrong idea of the reproductive instinct. later when the girl was woman grown she still clung to the old conception, deploring the sex-part of the marriage relation and feeling herself too refined to be moved by any such sensual urge. but the strong sex-instinct within her would not be downed. it was so insistent as to be an object of terror to her repressing instinct, which could not bring itself to acknowledge its presence. the fear that came to the surface was merely a disguised and symbolic representation of this real fear which was turning her life into a nightmare. the nausea and vomiting in this woman seemed to be symbolic of the disgust which she felt subconsciously at the thought of her own sex-desires, but sometimes the physical disturbances which accompany such phobias are the natural physical reactions to the constant fear state. indigestion, palpitation, and tremors are not in themselves symbolic of the inner trouble but may be the result of an overdose of the adrenal and thyroid secretions and the other accompaniments of fear. in such cases the real symptom is the fear, and the physical disturbance an incidental by-product of the emotional state. in any case a nervous symptom is always the sign of something else--a hieroglyph which must be deciphered before its real meaning can be discovered. summary =three kinds of people.= absurd as it sounds, "nerves" turn out to be a question of morals; a neurosis, an affair of conscience; a nervous symptom an unsettled ethical struggle. the ethical struggle is not unusual; it is a normal part of man's life, the natural result of his desire to change into a more civilized being. the people in the world may be divided into three classes, according to the way they decide the conflict. =the primitive.= the first class merely capitulate to their primitive desires. they may not be nervous, but it is safe to say that they are rarely happy. the voice of conscience is hard to drown, even when it is not strong enough to control conduct. happily it often succeeds in making us miserable, when we desert the ways that have proved best for our kind. the "immoral" person has not yet "arrived"; he simply disregards the collective wisdom of society and gives the victory to the primitive forces which try to keep man back on his old level. we cannot break the ideals by which man lives, and still be happy. =the salt of the earth.= the second class of people decide the conflict in a way that satisfies both themselves and society. they give the victory to the higher trends and at the same time make a lasting peace by winning over the energy of the undesirable impulses. by sublimation they divert the threatening force to useful work and turn it out into real life, using its steam to make the world's wheels go round. their love-force, unhampered by childish habits, is free to give itself to adult relationships or to express itself symbolically in socially helpful ways. =nervous people.= to the third class belong the people who have not finished the fight. these are the folk with "nerves," the people in whom the conflict is fiercest because both sides are too strong. the victory goes to neither side; the tug of war ends in a tie. since the energy of the nervous person is divided between the effort to repress and the effort to gain expression, there is little left for the external world. there is plenty of energy wasted on emotion, physical symptoms, phantasy, or useless acts symbolizing the struggle. a neurotic is a normal person, "only more so." his impulses are the same impulses as those of every other person; his complexes are the same kind of complexes, only more intense. he is an exaggerated human being. he may be only slightly exaggerated, showing merely a little character-weakness or a slight physical symptom, or he may be so intensified as to make life miserable for himself and everybody near him. it is quantity, not quality, that ails him, for he differs from his steady-going neighbor not in kind but in degree. more of him is repressed and a larger part of him is fixed in a childish mold. =tricking ourselves.= a neurosis is a confidence game that we play on ourselves. it is an attempt to get stolen fruit and to look pious at the same time,--not in order to fool somebody else but to fool ourselves. no nervous symptom is what it seems to be. it is an arch pretender. it pretends to be afraid of something it does not fear at all, or to ignore something that interests it intensely. it pretends to be a physical disease, when primarily it has nothing to do with the body; and the person most deluded is the one who "owns" the symptom. its purpose is to avoid the pain of disillusionment and to furnish relief to a distracted soul which dares not face itself. although the true meaning of a symptom is hidden, there is fortunately a clue by which it can be traced. sometimes it takes the art of a psychic detective to follow the clues down, down through the different layers of the subconscious mind, until the troublesome impulses and complexes are found and dragged forth,--not to be punished for breaking the peace but to be led toward reconciliation. but "that is another story," and belongs to another chapter. we are approaching the way out. part iii--the mastery of "nerves" chapter viii _in which we pick up the clue_ the way out the science of re-education there is a story of an irishman at the world's fair in chicago. although his funds were getting low, he made up his mind that he would not go home without a ride on a camel. for several minutes he stood before a sign reading: "first ride 25â¢, second ride 15â¢, third ride 10â¢." then, scratching his head, he exclaimed, "faith, and i'll take the third ride!" should there by any chance be a reader who, eager to find the way out without paying the price of knowledge, is tempted to say to himself "faith, and i'll begin with part iii," we give him fair warning that if he does so, he will in all probability end by putting down the book in a confused and skeptical frame of mind. it is difficult to find our way out of a maze without some faint idea of the path by which we got in. he who brings to this chapter the popular notion that nervousness is the result of worn-out nerve-cells, can hardly be expected to understand how it can be cured by a process of mental adjustment. suggestion to that effect can scarcely fail to appear to him faddish and unpractical. but once a person has grasped the idea that "nerves" are merely a slip in the cog of hidden mental machinery, and has acquired at least a working-knowledge of "the way the wheels go round," he can scarcely fail to understand that the only logical cure must consist in some kind of readjustment of this underground machinery. if "nerves" were physical, then only physical measures could cure, but as they are psychic, the only effective measures must be psychic. =gross misconceptions.= nervousness is caused by a lack of adjustment to the world as it is; therefore the only possible cure must be some sort of readjustment between the person's inner forces and the demands of the social world. as this lack of adjustment is concerned chiefly with the repressed instinct of reproduction, it is only natural that there should be people who believe that "the way out" lies in some form of physical satisfaction of the sex-impulse--in marriage, in changing or ignoring the social code, in homo-sexual relations or in the practice of masturbation. but we have only to look about us to see that this prescription does not cure. freud naã¯vely asks whether he would be likely to take three years to uncover and loosen the psychic resistances of his patients, if the simple prescription of sex-license would give relief. since there are as many married neurotics as single, it is evident that even marriage is not a sure preventive of nervousness. license, on the other hand, can satisfy only a part of the individual's craving. freud insists that the sex-instinct has a psychic component as well as a physical one, and that it is this psychic part which is most often repressed. he maintains that for complete satisfaction there must be psychic union between mates, and that gratification of the physical component of sex when dissociated from psychic satisfaction, results in an accumulation of tension that reacts badly on the whole organism. the psychic tension accumulating in adult sex-relations has its inception in the mistaken attitude on the part of the wife, who remains true to her childhood training that any pleasure in sex is vulgar; or on the part of the man, who reacts to the mood of the wife, or is held by his own unbroken mother-son complex; or on the part of both the tension piles up because of society's taboo upon rearing large families. as the first two factors in this lack of adjustment grew largely out of some kind of faulty education or from faulty reaction to early experiences, the only effective way to secure a better adaptation must be through a re-education which reaches down to that part of the personality that bears the stamp of the unfortunate early factors. =remaking ourselves.= as a matter of fact, the science of psychotherapy or mental treatment is simply the science of re-education,--a process designed to break up old unhealthy complexes which disrupt the forces of the individual, and to build up healthy complexes which adjust him to the social world and enable him to use his energy in useful ways. fortunately, minds can be changed. it is easier to make over an unhealthy complex than to make over a weak heart, to straighten out a warped idea than to straighten a bent back. remarkable indeed have been some of the transformations in people who are supposed to have passed the plastic period in life. while it is true that some persons become "set" in middle life, and almost impervious to new ideas, it is also true that a person at fifty has more richness of experience upon which to draw, more appreciation of the value of the good, than has a person at twenty. if he really wants to change himself, he can do wonderful things by re-education. the first step in this re-education is a grasp of the facts. if you want to pull yourself out of a nervous disorder, first of all learn as much as you can about the causes of "nerves," about the general laws of mind and body, and about your own mental quirks. if this is not sufficient, go to a specialist trained in psychotherapy and let him help you uncover those trouble-making parts of your personality which you cannot find for yourself. it is the purpose of this book to summarize the facts which most need to be known. let us now consider those methods which the psychopathologist finds most useful in helping his patients to self-knowledge and readjustment. =various methods.= as there are a number of schools of medicine, so there are a number of distinct methods of psychotherapy, each with its own theories and methods of procedure, and each with its ardent supporters. these methods may be classified into two groups. the first group includes those methods, hypnosis and psycho-analysis, which make a thorough search through the subconscious mind for the buried complexes causing the trouble, and might, therefore, be called "re-education with subconscious exploration." the other group, includes so-called explanation and suggestion, or methods of "re-education without subconscious exploration," which content themselves with making a general survey and building up new complexes without going to the trouble of uncovering the buried past. although the theory and the technique vary greatly, the aim of all these methods is the same,--the readjustment of the individual to life. re-education with subconscious exploration =hypnosis.= the method by which most of the important early discoveries were made is hypnosis, or artificial sleep, a method by which the conscious mind is dissociated and the subconscious brought to the fore. it was through hypnosis that freud, janet, prince, and sidis made their first investigations into the nature of nervousness and worked their first cures. with the conscious mind asleep and its inhibitions out of the way, a hypnotized patient is often able to remember and to disclose to the physician hidden complexes of which he is unaware when awake. hypnosis may thus be a valuable aid to diagnosis, enabling the physician to determine the cause of troublesome symptoms. he may then begin to make suggestions calculated to break up the old complexes and to build new ones, made up of more healthful ideas, desirable emotions and happy feeling-tones. as we have seen, a hypnotized subject is highly suggestible. his counter-suggestions inactivated, he believes almost anything told him and is extremely susceptible to the doctor's influence. the dangers of hypnosis have been much exaggerated. indeed, as an instrument in the hands of a competent physician, it is not to be feared at all. it has, however, its limitations. many times the very memories which need to be unearthed refuse to come to the surface. stubborn resistances are more likely to be subconscious than conscious, and may prove too strong to be overcome in this way. moreover, the road to superficial success is very inviting. it is easy to cure the symptom, leaving the ultimate cause untouched and ready to break out in new manifestations. the drug and drink habits may be broken up without making any attempt to discover the unsatisfied longings which were responsible for the habit. a pain may be cured without finding the mental cause of the pain or initiating any measures to guard against its return, and without giving the patient any insight into the inner forces with which he still has to deal. since nervousness is a state of exaggerated suggestibility and abnormal dissociation, many psychologists believe that it is unwise to employ a method which heightens the state of suggestibility and encourages the habit of dissociation. they feel that it is wiser to use less artificial methods which rest on the rational control of the conscious mind and make the patient better acquainted with his own inner forces and more permanently able to cope with new manifestations of those forces. they believe that the character of the patient is strengthened and his morale raised by methods which increase the sovereignty of reason and decrease the role of unreasoning suggestibility. =psycho-analysis.= freud's contribution has been not only a discovery of the general causes of nervousness, but a special means of locating the cause in any particular case. abandoning hypnosis, he developed another method which he called psycho-analysis. what chemical analysis is to chemistry, psycho-analysis is to the science of the mind. it splits up the mental content into its component parts, the better to be examined and modified by the conscious mind. psycho-analysis is merely a technical process for discovering repressed complexes and bringing them into consciousness, where they may be recognized for what they are and altered to meet the demands of real life. it is a device for finding and removing the cause of nervousness,--for bringing to light hidden desires which may be honestly faced and efficiently directed instead of being left to seethe in dangerous insurrection. in order permanently to break up a real neurosis, a man must first know himself and then change himself. he must gain insight into his own mental processes and then systematically set to work to change those processes that unfit him for life. we shall later find that a detailed self-discovery through psycho-analysis is not always necessary, and that a more general understanding of oneself is sufficient for the milder kinds of nervousness. but because of the promise which psycho-analysis holds out to those stubborn cases before which other methods are powerless; because of the invaluable understanding of human nature which it places at the disposal of all nervous people, who may profit by its findings without undergoing an analysis; and because of the flood of light which it sheds on the motives, conduct, and character of every human being, no educated person can afford to be without a general knowledge of psycho-analysis.[41] [footnote 41: it is unfortunate that the records of an analysis are too voluminous for use in so brief an account as this. since the report of one case would fill a book, and a condensed summary would require a chapter, we must refer to some of the volumes which deal exclusively with the psychoanalytic principles. for a list of these books, see bibliography.] =a chain of associations.= psycho-analysis is not, like hypnosis, based on dissociation; it is based on the association of ideas. its main feature is a process of uncritical thinking called "free association." to understand it, one must realize how intricately woven together are the thoughts of a human being and how trivial are the bonds of association between these ideas. one person reminds us of another because his hair is the same color or because he handles his fork in the same way. two words are associated because they sound alike. two ideas are connected because they once occurred to us at the same time. a subtle odor or a stray breeze serves to remind us of some old experience. connections that seem far-fetched to other people may be quite strong enough to bind together in our minds ideas and emotions which have once been associated, even unconsciously, in past experience. in this way, thoughts in consciousness and in the upper layers of the subconscious are connected by a series of associations, forming links in invisible chains that lead to the deepest, most repressed ideas. even a dissociated complex has some connection with the rest of the mind, if we only have the patience to discover it. therefore, by adopting a passive attitude, by simply letting his thoughts wander, by talking out to the physician everything that comes to his mind without criticizing or calling any thought irrelevant or far-fetched, and without rejecting any thought because of its painful character, the patient is helped to trace down and unearth the troublesome complex which may have been absolutely forgotten for many years. he is helped to relive the childhood experiences back of the over-strong habits which lasted into maturity. =resisting the probe.= naturally, it is not all fair sailing. the subconscious impulses which repressed the painful complex in the first place still shrink from uncovering it. in many cases the resistance is very strong. it, therefore, often happens that after a time the patient becomes restive; he begins to criticize the doctor and to ridicule the method. his mind goes blank and no thought will come; or he refuses to tell what does come. the nearer the probe comes to the sore spot, the greater the pain of the repressing impulses and the stronger the resistance. usually a strange thing happens; the patient, instead of consciously remembering the forgotten experiences, begins to relive them with his original emotions transferred on to the doctor. depending upon what person of his childhood he identifies with him, the patient develops either a strong affection or an intense antagonism to the physician, attitudes called in technical terms positive and negative transference. if the analyst is skilful, he is able to circumvent all the subterfuges of the resisting forces and to uncover and modify the troublesome complexes. sometimes this can be accomplished at one sitting, but more often it requires long hours of conversation. freud has spent three years on a single difficult case, and very frequently the analysis drags out through weeks or months. the amount of mental material is so great, especially in a person who is no longer young, that every analysis would probably be an interminable affair if it were not for three valuable ways of finding the clue and picking up the scent somewhere near the end of the trail. the first of these clues is nothing else than so despised a phenomenon as the patient's own night-dreams, which turn out to be not meaningless jargon, as we have supposed, but significant utterances of the inner man. =the message of the dream.= when freud rescued dreams from the mental scrap-basket and learned how to piece them together so that their message to man about himself became for the first time intelligible, he furnished the human race with what will probably be considered its most valuable key to the hidden mysteries of the mind. freeing the dream from the superstition of olden times and from the neglect of later days, freud was the first to discover that it is part and parcel of man's mental life, that it has a purpose and a meaning and that the meaning may be scientifically deciphered. it then invariably reveals itself to be not a prophecy for the future but an interpretation of the present and of the past, an invaluable synopsis of the drama which is being staged within the personality of the dreamer. as modern man has swung away from the idea of the dream as a warning or a prophecy, he has accepted the even more untrue conception of dreaming as the mere sport of sleep,--the "babble of the mind," the fantastic and insignificant freak-play of undirected mental processes, or the result of physical sensations without relation to the rest of mental life. no wonder, then, that freud's startling dictum, "a dream is a disguised fulfilment of a repressed wish," should be met with astonishment and incredulity. when a person is confronted for the first time with this statement, he invariably begins to cite dreams in which he is pursued by wild beasts, or in which his loved ones are seen lying dead. he then triumphantly asserts that no such dream could be the fulfilment of a wish. the trouble is that he has overlooked the word "disguised." like wit and some figures of speech, a dream says something different from what it means. it deals in symbols. its "manifest content" may be merely a fantastic and impossible scene without apparent rhyme or reason, but the "latent content," the hidden meaning, always expresses some urgent personal problem. although the dream may seem to be impersonal and unemotional, it nevertheless deals in every case with some matter of vital concern to the dreamer himself. it is a condensed and composite picture of some present problem and of some related childish repressed wish which the experiences of the preceding day have aroused. as frink says, a dream is like a cartoon with the labels omitted--absolutely unintelligible until its symbols are interpreted. although some dreams whose symbolism is that which man has always used, can be easily understood by a person who knows, many dreams are meaningless, even to an experienced analyst, until the patient himself furnishes the labels by telling what each bit of the picture brings to his mind. the dream, as a rule, merely furnishes the starting-point for free association. each symbol is an arrow pointing the way to forbidden impulses which are repressed in waking life but which find partial expression during sleep. the subconscious part of the conscience is still on the job, so the repressed desires can express themselves only in distorted ways which will not arouse the censor and disturb sleep. the purpose of the dream is thus two-fold,--to relieve the tensions of unsatisfied desire, and to do this in such a subtle way as to keep the dreamer asleep. sometimes it fails of its purpose, but when there is danger of our discovering too much about ourselves, we immediately wake up, saying that we have had a bad dream. it is at first difficult to believe that we are capable of this elaborate mental work while we are fast asleep. however, a little investigation shows us to be more clever than we realize. the subconscious mind, in its effort to satisfy both the repressing and the repressed impulses, carries on very complicated processes, disguises material by allowing one person to stand for another, two persons to stand for one, or one person to stand for two; it shifts emotion from important to trivial matters, dramatizes, condenses, and elaborates, with a skill that is amazing. we are all of us very clever playwrights and makers of allegories--in our sleep. also, we are all very clever at getting what we want, and the dream secures for us, in a way, something which we want very much indeed and which the world of social restraint or our own warped childish notion denies us. not every one can become an interpreter of dreams. it takes a skilled and patient specialist thoroughly to understand the process. but it is fortunate indeed that we possess such a valuable means of diagnosis when extraordinary conditions make it necessary to explore the subconscious in the search for trouble-making complexes.[42] [footnote 42: for further study of the dream, see freud: _interpretation of dreams_; and _general introduction to psycho-analysis_.] =the word-test.= although dreams furnish the main clues to buried complexes, they are by no means the only instrument of the psycho-analyst. another device, called the association word-test, has been developed by dr. carl jung of switzerland. the analyst prepares a list of perhaps one hundred words, which he reads one by one to the patient, hoping in this way to strike some of the emotional reactions of which the patient himself is unaware. the latter responds with the first word that comes into his mind, no matter how absurd it may seem. the responses themselves are often significant, but the time that elapses is even more so. it usually happens that it takes very much longer for some responses than for others. if a patient's average time is one or two seconds, some responses may take five or ten or twenty seconds. sometimes no word comes at all and the patient says that his mind is a blank. he coughs or blushes, grows pale or trembles, showing all the signs of emotion even when he himself has no notion of the cause. the significant word has hit upon a subconscious association with some emotional complex. the blocking of the mind is an effort of the resistance to keep the painful ideas out of consciousness. the telltale word then furnishes a starting point for further associations. one of my patients blocked on the word "long." instead of saying "short" or "pencil" or "road" or "day" or any other word which might naturally be associated with "long," she laughed and said that no word would come. finally an emotional memory came to light. it seems that this woman had been courted by a man whom she unconsciously loved, but whom she had "turned down" because she was ambitious for a career. after the man had moved to another town, my patient heard that he was engaged to another girl. she then realized that she loved him and began to long for him with her whole heart. the meaningful word "long" thus led us to one of the emotional memories for which we were seeking. ="chance" signs.= there are other clues to hidden inner processes, other sign-posts pointing to the cause of a neurosis. not only through dreams and through emotional reactions to certain words does the subconscious reveal its desires, but also through the little slips of the tongue and of the pen, the "chance" acts and unconscious mannerisms which are usually ignored as entirely insignificant. when we "make a break" and say what we secretly mean but wish to hide from ourselves or others; when we forget an appointment which part of us really wishes to avoid, or forget a name with which we are perfectly familiar; when we lose the pen so that we cannot write or the desk key so that we cannot work; when we blunder and drop things and do what we did not mean to do; then we may know--the normal as well as the nervous person--that our subconscious minds with their repressed desires are trying to get the reins and are partially succeeding. an example from my own life may illustrate the point. in building a number of houses, i had occasion often to use the word studding, but on every occasion, i forgot the word and always had to end lamely by saying "those pieces of timber that go up and down." each time the builder supplied the word, but the next time it was no more accessible. finally, the reason came to me. one day when i was a little child i looked out of the window and cried, "oh, see that great big beautiful horse." my grandmother exclaimed, "sh! sh! that is a stud horse." over-reaction to that impression repressed the word stud so successfully that as a grown woman i could not recall another word which happened to contain the same syllable. during an analysis a patient of mine who had a mother-in-law situation on her hands told me a dream of the night before. "i dreamed that my mother-in-law, who has really been very ill, was taken with a sinking-spell. i rushed to the telephone to call the doctor, but found to my terror that i could not remember his number." "what is his number?" i asked, knowing that she ought to know it perfectly. "two-eight-nine-six," she answered at once. the number really was 2876. asleep and awake, her repressed desire for release from the mother-in-law's querulous presence was attempting to have its way. in the dream, she avoided calling the doctor by forgetting his number entirely. awake, she evaded the issue by remembering a wrong number. in the dream she thinly disguised her desire by displacing the anxious emotion from the sense of her own guilty wishes to the idea of the mother-in-law's death. when confronted with this interpretation, the woman readily acknowledged its truth. even stammering, which has always been considered a physical disorder, has been proved, by psycho-analysis, to be the sign of an emotional disturbance. h. addington bruce reports the case of one of dr. brill's patients, a young man who had been stammering for several years. observation revealed the fact that his chief difficulty was with words beginning with k and although at first he firmly denied any significance to the letter, he later confessed that his sweetheart whose name began with k had eloped with his best friend and that he had vowed never to mention her name again. upon dr. brill's suggestion he tried to think of the unfaithful lover as miss w., but soon returned, saying that he was stammering worse than ever. investigation showed that the additional unpronounceable words contained the letter w. when he was induced to renounce his oath never to call the girl's name again, he found that he had no more difficulty with his speech.[43] [footnote 43: h. addington bruce; "stammering and its cure," _mcclure's_, february, 1913.] thus we see that even the halting tongue of a stammerer may point the way to the buried complex for which search is being made. since there is no accident in mental life, and since there is behind every action a force or group of forces, no smallest action is insignificant to the person trained to understand. if this at first seems disturbing, it is only because we do not realize that there is nothing within of which we need be ashamed. people are very much alike, especially in the deeper layers of their being. what belongs to the whole human race does not need to be hidden away in darkness. there is nothing to lose and everything to gain by an increasing understanding of the chance signals which reveal the forces at work within the depths of the mind. to the analyst every little unconscious act is a valuable clue pointing toward the end of his quest.[44] [footnote 44: for further discussion of this subject, see freud's _psycho-pathology of everyday life_, translated by a.a. brill.] =the aim of psycho-analysis.= as we have seen, the object of all this technique is the discovery and the removal of the resistances which have been keeping the emotional conflicts in the dark. it is a long step just to learn that there are resistances; and by reliving, bit by bit, the earlier experiences responsible for unfortunate habits, we find that the habits themselves lose much of their old power. they can be seen for what they are, and changed to suit present conditions. a wish is incomparably stronger when unconscious than when conscious; and the old stereotyped, automatic reactions tend to cease when once they have been seen for what they are. they become assimilated with the rest of the personality and modified by the mature attitudes of the conscious mind. the person then re-educates himself by the very act of discovering himself. in other cases, the uncovering is merely the first step in the process of re-education. the analyst then assumes the rã´le of educator, cutting away old shackles, breaking down false standards, building up new complexes, showing the patient the naturalness of his desires, inducing him to look at them as biologic facts, and showing him how to sublimate those which may not find direct expression; in fact, leading him out into the self-expression of a free, unhampered life.[45] [footnote 45: "it will be readily understood that in the reconstruction of the shattered purposes, the frustrated hopes and the outraged instincts which are found to lie at the source of those human woes we call 'nervous disorders,' there takes place a gradual transposition of values, a total recasting of ideas, and that through the whole process, education in the deepest meaning of the word, enters at last into its full sovereign rights."--trigant burrow.] among my patients at one time was a woman subject to terrible fits of despondency. she was happily married and enjoyed the marriage relationship, but could not free herself from a terrible sense of guilt and degradation, a sense which was so acute that she wanted to end her life. although she was an active member of a church, she was starving for the real message of the church, continually bound by a feeling of aloofness which made her a stranger in the midst of friends. psycho-analysis revealed an experience of her childhood which she had kept a secret all these years. it seems that when she was seven years of age an old minister had driven her into town and had made some sort of sex-approach on the way. although ignorant of its significance, the child was badly frightened and overcome with a sense of guilt. she had already inferred that such subjects were not to be mentioned and she hesitated long before telling even her mother. smoldering within her through the years had been this emotional complex about the sex-life and about people connected with a church, so that even as a grown woman the relationships of her mature years were completely ruined by her old childish reaction. with insight as to the cause of her trouble, she was able to modify her attitudes and to live a free and happy life. several years ago there came to me a man of exceptional intellectual ability, who for years had been totally incapacitated because of blind resistances built up in childhood. although married to a woman whom he thoroughly liked and admired, he was absolutely miserable in his married life. he had, in fact, a deep-rooted complex against marriage, and had only allowed himself to be captured because the woman, with whom he had been good friends, had cried when he refused to marry her. during analysis it transpired that as a little boy of four he had often seen his silly young mother cry because she could not have a new dress. he had taken her side and bitterly felt that she was abused by his father. later, at six, he had heard some coarse stories about sex to which he had over-reacted. still later he had heard the workmen on the farm say that they could not go to the gold-fields because they had wives and were held back by marriage. "there are no idle words where children are," and this little boy had built up such a strong complex against marriage that he could not possibly be happy as a grown man. he was as much crippled by the old scar as is an arm which is bent and stunted from a deep scar in the flesh. after the analysis had broken up the adhesions, he found himself free, able to give mature expression to his repressed and dissatisfied love-instincts. psycho-analysis is not a process of addition, but one of subtraction. like a surgical operation, it undoes the results of old injuries, removes foreign material, and gives nature a chance to develop freely in her own satisfactory way. re-education without subconscious exploration =simple explanation.= so far, "the way out" sounds rather involved. it seems to require a special kind of doctor and a complicated, lengthy process before the exact trouble can be determined. but, fortunately for the average nervous patient, this lengthy process of analysis is by no means always necessary. people with troublesome nervous symptoms, and even those who have had a serious breakdown, are constantly being cured by a kind of re-education which breaks up subconscious complexes without trying to bring them to the surface. if the dead past can be let alone, so much the better. sometimes a bullet buried in the flesh sends up a constant stream of discomfort until it is dug out and removed; but if it has carried in no infection and the body can adjust itself, it is usually considered better to let it remain. the subconscious makes its own deductions. if resistances are not too strong it is often possible to introduce healthy ideas by way of the conscious reason, to break up old habits, and make over the mentality without going to the trouble of uncovering some of the reactions which are responsible for the difficulty. =moral hygiene.= because this is true, there has grown up a kind of psychotherapy which is known as simple explanation, or persuasion. as usually practised, this kind of re-education pays very little attention to the ultimate cause of "nerves." it has little to say about repressed instincts or the real reasons for fearful emotions and physical symptoms. instead, it attacks the symptom itself, contenting itself with teaching the patient that his trouble is psychic in origin; that it is based on exaggerated suggestibility and uncontrolled emotionalism; that it is made out of false ideas about the body, illogical conclusions, and unhealthy feeling-tones; and that it may be cured by a kind of moral hygiene, which breaks up these old habits and replaces them with new and better ones. it tries to inculcate the cheerful attitude of mind; to give the patient the conviction of power; to correct his false ideas about his stomach, his heart, or his head; to train him out of his emotionalism; to lead him into a state of mind more largely controlled by reason; and to make him find some useful and absorbing work. this kind of mental and moral treatment has been sufficient to cure many neuroses of long standing. in cases that are helped by this method, the patient's love-force, robbed of the material out of which it has woven its disguise, and trained out of its bad habits by re-education, automatically makes its own readjustments and forces new channels for itself out into more useful activities. very many nervous persons seem to need nothing more than this simple kind of help. =when simple explanation does not explain.= for very many cases, however, this procedure, good as it is, does not go deep enough. although it gives a sound objective education about the facts of one's body, it furnishes only the most superficial subjective knowledge of one's inner life. if the inner struggle be bitter, the competing forces will hold on to their poor refuge in the symptom, despite any number of explanations that the symptom can have no physical cause. sometimes it is enough for a person to be shown that he is too suggestible, but often it is far more helpful for him to get an inkling as to why he likes unhealthy suggestions, and to understand something of his starved instincts which he may learn to satisfy in better ways. psychological explanation between the two extremes of the cases which need a real analysis and those which are cured by simple explanation, i have found the great bulk of nervous cases. to simple explanation with its highly useful information, i therefore add what might be called psychological explanation, a re-education which makes use of all that illuminating material unearthed by the explorations of hypnosis and especially of psycho-analysis. along with correct ideas about such matters as digestion, sleep, and fatigue, i give, so far as the patient is able to understand, a comprehension of the rights of the denied instincts, the ways of the subconscious, the fettering hold of unfortunate childish habits, the various mental mechanisms by which we fool ourselves, and the ways by which we may make better adaptations. =according to the patient.= the treatment varies according to the nature of the trouble, and is somewhat dependent on the mentality of the patient. there are many people who would only be confused by being forced into a study of mental phenomena. not being students, they would be more bewildered than helped by the details of their inner mechanisms. others, of studious habits and inquiring minds, are encouraged to browse at will in a library of psychotherapy and to learn all that they can from the best authorities. in any case, i give the patients as much as they are able to take of my own understanding of the subject. there are no secrets in this method. the patient is treated as a rational human being who has nothing to lose and everything to gain by the fullest knowledge that he is able to acquire. without forcing him to plunge in over his depth, i encourage him to understand himself to the fullest possible extent. besides individual private conferences, we have twice a day an informal gathering of all the patients in my household--"the family" as we like to call ourselves--for a reading or talk on the various ways of the body and the mind, which need to be understood for normal living and for the cure of nerves. very often people of only average education, long without the opportunity of study, gain in a surprisingly short time enough insight to make new adaptations and cure themselves. for this, a college education is not nearly so important as an open mind. it is because of the success of this method that i have been encouraged to reach a larger number of people by means of a book, based on the same plan of re-education. =explanation vs. suggestion.= re-education through this kind of explanation is simply a matter of learning the truth and acting upon it. it is a process of real enlightenment, and is very different from suggestion which trades upon the patient's credulity, increasing his already exaggerated suggestibility. freud illustrates the difference between suggestion and psycho-analysis by saying that suggestion is like painting and psycho-analysis like sculpture. painting adds something from the outside, plastering over the canvas with extraneous matter, while sculpture cuts away the unnecessary material and reveals the angel in the marble. so suggestion covers over the real trouble by crying, "peace, peace, when there is no peace." without attempting to remove the cause, it says to the patient: "you have no pain. you are not tired. you will sleep to-night. you will be cheerful." sometimes the suggestion works and sometimes it does not, but at best the relief is likely to be a mere temporary makeshift. the symptom may be relieved, but the character is not changed and therefore no permanent relief is assured. it is far better for a nervous person to say to himself, "there is something wrong and i am going to find it," than to keep repeating over and over, "there is nothing wrong," and so on through a list of half-believed autosuggestions. on the other hand, psycho-analysis, and this kind of re-education based on psycho-analytic principles, do not pay a great deal of attention to the individual symptom. instead of adding from without they try to take away whatever has proved a hindrance to normal growth and development, and to remove unnecessary resistances which are responsible for the symptom, and which have been holding the patient back from the fullest self-expression. =incantation vs. knowledge.= there came to me one day a well-known public woman who had suffered from nervous indigestion for many years. as she was able to be with me for only one night, we had time for just one conversation, but in that time she discovered what she was doing and lost her indigestion. in the course of the conversation she turned to me, saying: "doctor, i know what a force suggestion is. i believe in its power. will you tell me why i have not been able to cure myself of this trouble? every night after i go to bed i repeat over and over these bible verses," naming a number of passages relating to god's goodness and care for his children. my answer was something like this: "you are too intelligent a woman to be cured by an incantation. when you feel surging up within you the sense of god's goodness, or when you actually want to realize his loving kindness, then by all means repeat the verses. but don't prostitute those wonderful words by making them into a charm and then expect them to cure your indigestion. it is a desecration of the words and a denial of your own intelligence. autosuggestion is a powerful force, but real psychotherapy is based not on the mechanical repetition of any set of words, but on a knowledge of the truth." =the "bullying method."= sometimes, to be sure, explanation is not enough. the brain paths between the associated ideas are so deeply worn that no amount of persuasion avails. it is easy for the doubter to say: "well, that sounds very well, but my case is different. i have tried over and over again and i know." with people of this sort, an ounce of demonstration is worth a pound of argument. by way of illustration we might mention the man who couldn't eat eggs. to be sure, he had tried many times but always had suffered the most intense cramps in his stomach, and no amount of talk could make him believe that an egg was not poison to him. i took the straight road of simply proving to him that he was mistaken, and had him eat an egg. after a time of apprehension and retching, he vomited the egg, thinking, of course, that he had proved his point. to his astonishment, i said, "now, let's go and eat another." with great consternation, he finally complied, evidently expecting to die on the spot; but as i immediately prescribed a game of tennis, he scarcely had time to think of the pain, which in fact failed to appear. however, as he thereafter insisted on eating four eggs a day,--with eggs at top-notch price i decided that the joke was on the doctor! =enjoying the right things.= in substituting healthful complexes for unhealthful ones, psychotherapy not only changes ideas and emotions, but alters the feelings of pleasure or pain that are bound up with the ideas. dr. tom a. williams writes: "the essence of psychotherapy and education is to associate useful activities with agreeable feeling-tones and to dissociate from injurious acts the agreeable feeling-tones that may have been acquired." right character consists not so much in enjoying things as in enjoying the right things. some people enjoy being martyrs. they love to tell about the terrible strain they have been under, the amount of work they have done, or the number of times they have collapsed. one of my patients gave every evidence of satisfaction as he told about his various breakdowns. "the last time i was ill," or "that time when i was in the sanatorium," were frequent phrases on his lips. finally, after i had asked him if he would boast about the number of times he had awkwardly fallen down in the street, and had shown him that a neurosis is not really a matter to be proud of, he saw the point and stopped taking pleasure in his mistakes. such signs of pleasure in the wrong things are evidence of suppressed wishes which we do not acknowledge but try to gratify in indirect ways.[46] the pleasure which ought to be associated with the idea of good work well done has somehow been switched over to the idea of being an invalid. the satisfaction which ought to go with a sense of power and ability to do things has attached itself to the idea of weakness and inability. the pleasurable feeling-tone which normally belongs to ministering to others, regresses in the nervous invalid to the infantile satisfaction of being ministered unto. [footnote 46: for a further elaboration of this theme, see holt: _the freudian wish_.] but these things are only a habit. a good look in the mirror soon makes one right about face and start in the other direction. once started, a good habit is built up with surprising ease. it is really much more satisfying to cook a good dinner for the family's comfort than to think about one's ills; much pleasanter to enjoy a good meal than to insist on hot water and toast. once we have satisfied our suppressed longings in more desirable ways, or by a process of self-training have initiated a new set of habits, we feel again the old zest in normal affairs, the old interest and pleasure in activities which add to the joy of life. thus does re-education fit a man to take his place in the world's work as a socially useful being, no longer a burden, but a contributor to the sum total of human happiness. summary =knowing and doing.= having set out to learn how to outwit our nerves, we are now ready to sum up conclusions and in the following chapters to apply them to the more common nervous symptoms. it has been shown that a nervous person is in great need of change,--not, indeed, a change in climate or in scene, in work or in diet, but a change in the hidden recesses of his own being. outwitting nerves means first and foremost changing one's mind, an inner and spiritual process very different from the kind of change which used to be prescribed for the nervous invalid. as putnam says, the slogan of the suggestion-school of psychotherapy has always been, "you can do better if you try"; while that of the psycho-analytic school is, "you can do better when you know." refuting the old adage, "where ignorance is bliss 'tis folly to be wise," the best methods of psychotherapy insist that the first step in any thorough-going attempt to change oneself must be the great step of self-knowledge. as the conflicts which result in "nerves" are always far beyond those mental regions which are open to scrutiny, a real self-knowledge requires an examination of the half-conscious or wholly unconscious longings which are usually ignored. a real understanding of self comes only when one is willing, to analyze his motives until he sees the connection between them and his nervous symptoms, which are but the symbolic gratification of desires he dares not acknowledge. although these deeply buried complexes are the real force behind a nervous illness, the material out of which the symptoms are manufactured is taken largely from superficial misconceptions concerning the bodily functions. it is therefore a great help, also, to possess a fund of information,--not technical nor detailed but accurate as far as it goes,--about the more important workings of the bodily machinery. a little knowledge about the actual chemistry of fatigue and the way it is automatically cared for by the body is likely to do away with the idea of nervous exhaustion as resulting from accumulation of fatigue. a simple understanding of the biological and physiological facts concerning the assimilation of food and the elimination of waste material leaves the intelligent person less ready to convert his psychic discomfort into indigestion and constipation. chapters ix to xiii in this book, which at first glance may seem to belong to a work on physiology rather than on psychology are designed to give just such needed insight. but knowing the truth is only the first half of the way out. every neurosis is a deliberate choice by a part of the personality. self-discovery is helpful only when it leads to better ways of self-expression. the final aim of psychotherapy is the happy adjustment of the individual to the demands of society and the establishment of useful outlets for his energy. this phase of the subject will be discussed more fully in chapter xvi. =the future hope.= much has been said about the cure of a neurosis. there are enough people already in the maze of nervousness to warrant the setting up of numerous signs reading, "this way out." but after all, is not a blocking of the way in of vastly more importance? as it is always easier to prevent than to cure, so it is easier to train than to reform. if re-education is the cure, why is not education the ounce of prevention which shall settle the problem for all time? if the general public understood what "nerves" are, it is hardly conceivable that there could be so many breakdowns as there are at present. if a man's family and friends, to say nothing of himself, understood what he is doing when he suddenly collapses and has to quit work, it is not likely that he would choose that way out of his difficulties. most important of all, when parents know that the foundation of nervousness is laid in childhood, they will see to it that their children are started right on the road to health. when fathers and mothers realize that an over-strong bond between parents and children is responsible for a large proportion of nervous troubles, most of them will make sure that such exaggeration is not allowed to develop. and, finally, when parents are freed from their "conspiracy of silence" by a reverent attitude toward the whole of life, their very saneness will impart to their children a wholesome respect for the reproductive instinct. there will then be found in the next generation fewer half-starved men and women carrying the burden of unnecessary repressions and the pain of unsatisfied yearnings. not that such a day will usher in the millennium. we are not suggesting a panacea for all the social ills. there is an inevitable conflict between the instinctive urge of the life-force and the demands of society, a conflict which makes men and women either finer or baser, according to the way they handle it. what is claimed is that the right kind of education--using the word in its largest, deepest sense--will remove the most fruitful cause of nervousness by taking away the extra burden of misconception and making it easier for people to be "content with being moral."[47] [footnote 47: frink: _morbid fears and compulsions._] chapter ix _in which we discover new stores of energy and learn the truth about fatigue_ that tired feeling unfailing resources "they that wait upon the lord shall renew their strength. they shall mount up with wings as eagles. they shall run and not be weary. they shall walk and not faint." it is safe to say that many a person loves this promise of the prophet isaiah without taking it in anything like a literal sense. the words are considered to be so figurative and so highly spiritualized that they seem scarcely to relate at all to this earthly life, much less to the possibilities of these physical bodies. besides the nervous folk who feel themselves so weary that they scarcely have strength to live, there are thousands upon thousands of men and women who are called normal but who have lost much of the joy of life because they feel their bodies inadequate to meet the demands of everyday living. to such men and women the biblical promise, "as thy day, so shall thy strength be," comes now as the message of modern science. nature is not stingy. she has not given the human race a meager inheritance. she did not blunder when she made the human body, nor did she allow the spirit of man to develop a civilization to whose demand his body is not equal. after its long process of development through the survival of the fittest, the human body, unless definitely diseased, is a perfectly adequate instrument, as abundantly able to cope with the complex demands of modern society as with the simpler but more strenuous life of the stone age. the body has stored within its cells enough energy in the shape of protein, carbohydrate and fat to meet and more than meet any drains that are likely to be made upon it, either through the monotony of the daily grind or the excitement of sudden emergency. nature never runs on a narrow margin. her motto seems everywhere to be, "provide for the emergency, enough and to spare, good measure, pressed down, running over." she does not start her engines out with insufficient steam to complete the journey. on the contrary, she has in most instances reserve boilers which are almost never touched. as a rule the trouble is not so much a lack of steam as the ignorance of the engineer who is unacquainted with his engine and afraid to "let her out." ="the energies of men."= perhaps nothing has done so much to reveal the hidden powers of mankind as that remarkable essay of professor william james, "the energies of men."[48] listen to his introductory paragraph as he opens up to us new "levels of energy" which are usually "untapped": [footnote 48: james: _on vital reserves_.] every one knows what it is to start a piece of work, either intellectual or muscular, feeling stale--or _cold_, as an adirondack guide once put it to me. and everybody knows what it is to "warm up to his job." the process of warming up gets particularly striking in the phenomenon known as the "second wind." on usual occasions we make a practice of stopping an occupation as soon as we meet the first effective layer (so to call it) of fatigue. we have then walked, played or worked "enough," so we desist. that amount of fatigue is an efficacious obstruction on this side of which our usual life is cast. but if an unusual necessity forces us to press onward, a surprising thing occurs. the fatigue gets worse up to a certain critical point, when gradually or suddenly it passes away, and we are fresher than before. we have evidently tapped a level of new energy, masked until then by the fatigue-obstacle usually obeyed. there may be layer after layer of this experience. a third and fourth "wind" may supervene. mental activity shows the phenomenon as well as physical, and in exceptional cases we may find, beyond the very extremity of fatigue-distress, amounts of ease and power that we never dreamed ourselves to own, sources of strength habitually not taxed at all, because habitually we never push through the obstruction, never pass those early critical points. again professor james says: of course there are limits; the trees don't grow into the sky. but the plain fact remains that men the world over possess amounts of resource which only very exceptional individuals push to their extremes of use. but the very same individual, pushing his energies to their extreme, may in a vast number of cases keep the pace up day after day, and find no "reaction" of a bad sort, so long as decent hygienic conditions are preserved. his more active rate of energizing does not wreck him; for the organism adapts itself, and as the rate of waste augments, augments correspondingly the rate of repair.[49] [footnote 49: ibid., pp. 6-7.] another psychologist, boris sidis, writes: "but a very small fraction of the total amount of energy possessed by the organism is used in its relation with the ordinary stimuli of its environment."[50] these men--professor james and dr. sidis--represent not young enthusiasts who ignorantly fancy that every one shares their own abundant strength, but careful men of science who have repeatedly been able to unearth unsuspected supplies of energy in "worn out" men and women, supposed to be at the end of their resources. every successful physician and every leader of men knows the truth of these statements. what would have happened in the great war if marshal foch had not known that his men possessed powers far beyond their ken, and had not had sublime faith in the "second wind"? [footnote 50: sidis: p. 112 of the composite volume _pychotherapeutics_.] =what about being tired?= if all these things are true, why do people need to be told? if man's equipment is so adequate and his reserves are so ample, why after all these centuries of living does the human race need to learn from science the truth about its own powers? the average man is very likely to say that it is all very well for a scientist sitting in his laboratory to tell him about hidden resources, but that he knows what it is to be tired. is not the crux of the whole question summed up in that word "tired"? if we do not need to rest, why should fatigue exist? if the purpose of fatigue seems to be to slow down our efforts, why should we disregard it or seek to evade its warnings? the whole question resolves itself into this: what is fatigue? in view of the hampering effect of misconception on this point, it is evident that the question is not academic, but intensely practical. we shall find that fatigue is of two kinds,--true and false, or physical and moral, or physiological and nervous,--and that while the two kinds feel very much alike, their origin and behavior are quite different. physiological fatigue =fatigue, not exhaustion.= in the first place, then, fatigue very seldom means a lack of strength or an exhaustion of energy. the average man in the course of a lifetime probably never knows what it is to be truly exhausted. if he should become so tired that he could in no circumstances run for his life, no matter how many wild beasts were after him, then it might seem that he had drained himself of all his store of energy. but even in that case, a large part of his fatigue would be the result of another cause. =a matter of chemistry.= true fatigue is a chemical affair. it is the result of recent effort,--physical, mental, or emotional,--and is the sum of sensations arising from the presence of waste material in the muscles and the blood. the whole picture becomes clear if we think of the body as a factory whose fires continuously burn, yielding heat and energy, together with certain waste material,--carbon dioxide and ash. within man's body the fuel, instead of being the carbon of coal is the carbon of glycogen or animal starch, taken in as food and stored away within the cells of the muscles and the liver. the oxygen for combustion is continuously supplied by the lungs. so far the factory is well equipped to maintain its fires. nor does it fail when it comes to carrying away waste products. like all factories, the body has its endless chain arrangement, the blood stream, which automatically picks up the debris in its tiny buckets--the blood-cells and serum--and carries it away to the several dumping-grounds in lungs, kidneys, intestines, and skin. besides the products of combustion, there are always to be washed away some broken-down particles from the tissues themselves, which, like all machinery, are being continuously worn out and repaired. by chemical tests in the laboratory, the physiologist finds that a muscle which has recently been in violent exercise contains among other things carbon dioxid, urea, creatin, and sarco-lactic acid, none of which are found in a rested muscle. since all this debris is acid in reaction and since we are "marine animals," at home only in salt water or alkaline solution, the cells must be quickly washed of the fatigue products, which, if allowed to accumulate, would very soon poison the body and put out the fires. =no back debts.= the human machine is regulated to carry away its fatigue products as fast as they are made, with but slight lagging behind that is made good in the hours of sleep, when bodily activities are lessened and time is allowed for repair. unless the body is definitely diseased, it virtually never carries over its fatigue from one day to another. in the matter of fatigue, there are no old debts to pay. nature renews herself in cycles, and her cycle is twenty-four hours,--not nine or ten months as many school-teachers seem to imagine, or eleven months as some business men suppose. in order to make assurance doubly sure, many set apart every seventh day for a rest day, for change of occupation and thought, and for catching up any slight arrears which might exist. but the point is that a healthy body never gets far behind. if through some flaw in the machine, waste products do pile up, they destroy the machine. if the heart leaks or the blood-cells fail in their carrying-power, or if lungs, kidneys or skin are out of repair, there is sometimes an accumulation of fatigue products which poisons the whole system and ends in death. but the person with tuberculosis or heart trouble does not usually allow this to happen. the body incapacitated by disease limits its activities as closely as possible within the range of its power to take care of waste matter. even the sick body does not carry about its old toxins. the man who had not eliminated the poisons of a month-old effort would not be a tired man. he would be a dead man. =a sliding scale.= if all this be true, real fatigue can only be the result of recent effort. if one is still alive, the results of earlier effort must long since have disappeared. the tissue-cells retain not the slightest trace of its effects. fatigue cannot possibly last, because it either kills us or cures itself. up to a certain point, far beyond our usual high-water mark, the more a person does the more he can do. as professor james has pointed out, the rate of repair increases with the rate of combustion. under unusual stress, the rate of the whole machine is increased: the heart-pump speeds up, respirations deepen and quicken, the blood flows faster, the endless chain of filling and emptying buckets hurries the interchange of oxygen and carbon dioxid, until the extreme capacity is reached and the organism refuses to do more without a period of rest. the whole arrangement illustrates the wonderful provisions of nature. although each individual is continuously manufacturing enough carbonic-acid gas to kill himself in a very few minutes, he need not be alarmed for fear that he may forget to expel his own poisons. nobody can hold his breath for more than a few minutes. the naughty baby sometimes tries, but when he begins to get black in the face, he takes a breath in spite of himself. the presence of carbonic-acid gas in the circulation automatically regulates breathing, and the greater the amount of gas the deeper the breath. the faster we burn the faster we blow. as with breathing, so with all the rest of elimination and repair. the body dares not get behind. ="second wind."= a city man frequently sets out on a mountain tramp without any muscular preparation for the trip. he walks ten or fifteen miles when his average is not over one or two. sometimes after a few hours he feels himself exhausted, but a glorious view opens out before him and he goes on with new zest. he has merely increased his rate of repair and drawn on a new stock of energy. that night he is tired, and the next day he is likely to be stiff and sore. there is a little fatigue left in him, but it takes only a day or two for the body to be wholly refreshed, especially if he hastens the process by another good walk. up to a certain point, far beyond our usual limit, the more we do, the more we can do. one day after a long walk my little daughter said that she could go no farther and waited to be carried. but she soon spied a dog on ahead and ran off after him with new zest. she followed the dog back and forth, running more than a mile before she reached home, and then in the exuberance of her spirits, ran around the house three times. =the emotions again.= what is the key that unlocks new stores of energy and drives away fatigue? what is it in the amateur mountain-climbers that helps the body maintain its new standard? what keeps indefatigable workers on the job long after the ordinary man has tired? is it not always an invigorating emotion,--the zest of pursuit, the joy of battle, intense interest in work, or a new enthusiasm? all great military commanders know the importance of morale. they know that troops can stand more while they are going forward than while running away, that the more contented and hopeful they are, the better fighters they make; discouragement, lack of interest, the fighting of a losing game, dearth of appreciation, futility of effort, monotony of task, all conspire in soldier or civilian to use up and to lock up energy which might have been available for real work. approaching the matter from a new angle, we find once more that the difference between strength and weakness is in many cases merely a difference in the emotions and feeling-tones which habitually control. fatigue is a safety-device of nature to keep us within safe limits, but it is a device toward which we must not become too sensitive. as a rule it makes us stop long before the danger point is reached. if we fall into the habit of watching its first signals, they may easily become so insistent that they monopolize attention. attention increases any sensation, especially if colored by fear. fear adds to the waste matter of fatigue little driblets of adrenalin and other secretions which must somehow be eliminated before equilibrium is reestablished. this creates a vicious circle. we are tired, hence we are discouraged. we are discouraged, hence we are more tired. this kind of "tire" is a chemical condition, but it is produced not by work but by an emotion. he who learns to take his fatigue philosophically, as a natural and harmless phenomenon which will soon disappear if ignored, is likely to find himself possessed of exceptional strength. we can stand almost any amount of work, provided we do not multiply it by worry. we can even stand a good deal of real anxiety provided it is not turned in on ourselves and directed toward our own health. ="decent hygienic conditions."= if fatigue products cannot pile up, why is extra rest ever needed? because there is a limit to the supply of fuel. if the fat-supply stored away for such emergencies finally becomes low, we may need an extra dose of sleeping and eating in order to let the reservoirs fill again. but this never takes very long. the body soon fills in its reserves if it has anything like common-sense care. the doctrine of reserve energy does not warrant a careless burning of the candle at both ends. it presupposes "decent hygienic conditions,"--eight hours in bed, three square meals a day, and a fair amount of fresh air and exercise. ="over there."= on the other hand, the stories that floated back to us from the war zone illustrate in the most powerful way what the human body can do when necessity forbids the slightest attention to its needs. one of the best of these stories is dorothy canfield's account of dr. girard-mangin, "france's fighting woman doctor." better than any abstract discussion of human endurance is this vibrant narrative of that little woman, "not very strong, slightly built, with some serious constitutional weakness," who lived through hardships and accomplished feats of daring which would have been considered beyond the range of possibility--before the war. think of her out there in her leaky makeshift hospital with her twenty crude helpers and her hundreds of mortally sick typhoid patients; four hundred and seventy days of continuous service with no place to sleep--when there was a chance--except a freezing, wind-swept attic in a deserted village. think of her in the midst of that terrible battle of verdun, during four black nights without a light, among those delirious men, and then during the long, long ride with her dying patients over the shell-swept roads. listen to her as she speaks of herself at the end of that ride, without a place to lay her head: "oh, then i did feel tired! that morning for the first time i knew how tired i was, as i went dragging myself from door to door begging for a room and a bed. it was because i was no longer working, you see. as long as you have work to do you can go on." then listen to her as she receives her orders to rush to a new post, before she has had time to lay herself on the bed she has finally found. "then at once my tiredness went away. it only lasted while i thought of getting to bed. when i knew we were going into action once more, i was myself again." watch her as she rides on through the afternoon and the long dangerous night; as she swallows her coffee and plum-cake, and operates for five hours without stopping; as she sleeps in the only place there is--a "quite comfortable chair" in a corner; and as she keeps up this life for twenty days before she is sent--not on a vacation, mind you, but to another strenuous post.[51] [footnote 51: dorothy canfield: _the day of glory._] this brave little woman is not an isolated example of extraordinary powers. the human race in the great war tapped new reservoirs of power and discovered itself to be greater than it knew. professor james's assertions are completely proved,--that "as a rule men habitually use only a small part of the powers which they actually possess," and that "most of us may learn to push the barrier (of fatigue) further off, and to live in perfect comfort on much higher levels of power." =how?= the practical question is: how may we--the men and women of ordinary powers, away from the extraordinary stimulus of a crisis like the great war--attain our maximum and drop off the dreary mantle of fatigue which so often holds us back from our best efforts? it may be that the first step is simply getting a true conception of physical fatigue as something which needs to be feared only in case of a diseased body, and which is quite likely to disappear under a little judicious neglect. in the second place, fatigue shows itself to be closely bound up with emotions and instincts. the great releasers of energy are the instincts. what but the mothering instinct and the love of country could uncover all those unsuspected reserves of dr. girard-mangin and others of her kind? what is it but the enthusiasm for work which explains the indefatigable energy of edison and roosevelt? if the wrong kind of emotion locks up energy, the right kind just as surely unlocks great stores which have hitherto lain dormant. if most people live below their possibilities, it is either because they have not learned how to utilize the energy of their instinctive emotions in the work they find to do, or because some of their strongest instincts which are meant to supply motive power to the rest of life are locked away by false ideas and unnecessary repressions, and so fail to feed in the energy which they control. in such a case, the "spring tonic" that is needed is a self-knowledge which shall release us from hampering inhibitions and set us free for enthusiastic self-expression. nervous fatigue _what of the nervous invalid?_ if the normal man lives constantly below his maximum, what shall we say of the nervous invalid? fatigability is the very earmark of his condition. in many instances he seems scarcely able to raise his hand to his head. sometimes he can scarcely speak for weariness. frequently to walk a block sends him to bed for a week. i once had a patient who felt that she had to raise her eyelids very slowly for fear of over-exertion. she could speak only about two or three words a day, the rest of the time talking in whispers. she could not raise a glass to her lips if it were full of water, but could manage it if only half full. a person nearly dead with some fatal disease does not appear more powerless than a typical neurasthenic. if it he true that accumulation of fatigue is promptly fatal, what shall we say of the woman who says that she is still exhausted from the labor of a year ago,--or of ten years ago? what of the business man who travels from sanatorium to sanatorium because five years ago he went through a strenuous year? what of the college student who is broken down because he studied too hard, or the teacher who is worn out because of ten hard years of teaching? there can be but one answer. no matter what their feelings, they can be suffering from no true physiological fatigue. something very real has happened to them, but only through ignorance and the power of suggestion can it be called fatigue and attributed to overwork. =stories of real people.= perhaps if we look over the stories of a few people who have been members of my household, we may work our way to an understanding of the truth. we give only the barest outline of the facts, thinking that the cumulative effect of a number of cases will outweigh a more detailed description of one or two. the most casual survey shows that whatever it was that burdened these fine men and women, it was not lack of energy. no matter how extreme had been their exhaustion, they were able at once, without rest or any other physical treatment, to summon strength for exertions quite up to those of a normal person. the second point that stands out clearly to any one acquainted with these inner histories is the conviction that in each case the trouble was related in some way to the unsatisfied love-life, to the insistent and thwarted instinct of reproduction. in some cases no search was made for the cause. the simple explanation that there was no lack of power was sufficient to release inhibited energy. but in every case where the cause was sought, it was found to be some outer lack of satisfaction, or some inner repression of the love-force. =from prostration to tennis.= one young woman, miss a., had suffered for ten years from the extremest kind of fatigue. she could not walk a block without support and without the feeling of great exhaustion. before her illness she had had a sweetheart. not understanding her normal physical sensations when he was near, she had felt them extremely wicked and had repressed them with all her strength. later, she broke off the engagement, and a little while after developed the neurosis. within a week after coming to my house, she was playing tennis, walking three miles to church, and generally living the life of a normal person. =making her own discoveries.= then there was miss b. who for four years had been "exhausted." she had such severe pains in her legs that she was almost helpless. if she sewed for half an hour on the sewing machine, she would be in bed for two weeks. although she was engaged to be married, she could not possibly shop for her trousseau. two years before, a very able surgeon had been of the opinion that the pain in the legs was caused by an ovarian tumor. he removed the tumor, assuring the patient that she would be cured. however, despite the operation and the force of the suggestion, the pains persisted. after she had been with me for a few days, she sewed for an hour on the machine. in a day or so she took a four-mile walk in a caã±on near the house and, on returning in the afternoon, walked two and a half miles down town to do some shopping. i did not make an analysis in her case because she recovered so quickly,--going home well within two weeks. but she declared that she had found the cause while reading in one of the books on psychology. i had my suspicions that the long-drawn-out engagement had something to do with the trouble, but i did not confirm my opinion. a long engagement, by continually stimulating desire without satisfying it, only too often leads to nervous illness. =afraid of heat.= professor x., of a large eastern college, had been incapacitated for four years with a severe fatigue neurosis and an intense fear of heat. constantly watching the weather reports, he was in the habit of fleeing to the maine coast whenever the weather-prophet predicted warm weather. after a short reã«ducation, he discovered that his fatigue was symbolic of an inner feeling of inadequacy, and that it bore no relation to his body. discarding his weariness and throwing all his energies into the liberty loan campaign, he found himself speaking almost continuously throughout one of the hottest days in the history of california, with the thermometer standing at 107 degrees. after that he had no doubt as to his cure. =in bed from fear.= miss c. was carried into my house rolled in a blanket. she had been confined to her bed except for fifteen minutes a day, during which time she was able to lie in a hammock! it seems that her illness was the result of fear, an over-reaction to early teaching about self-abuse. her mother had frightened her terribly by giving her the false idea that this practice often leads to insanity. having indulged in self-abuse, she believed herself going insane, and very naturally succumbed to the effects of such a fear. after a few days of re-education, she was as strong as any average person. having no clothing but for a sick-room, she borrowed hat, skirt, and shoes, and walked to church, a three-mile walk. =empty hands.= miss y., a fine woman of middle age, suffering from extreme fatigue could neither sleep nor eat. she could only weep. she had spent her life taking care of an invalid girl who had recently died. now her hands were empty. like many a mother whose family has grown up, she had no outlet for her mothering instinct, and her sense of impotency expressed itself in the only way it knew how,--through her body. as there is never any lack of unselfish work to be done, or of people who need mothering, she soon found herself and learned how to sublimate her energy in useful activities. =defying nature.= one young man from wyoming had felt himself obliged to give up his business because he could neither work nor eat. it soon cropped out that he and his wife had decided that they must not have any children. with a better understanding of the great forces which they were defying, his strength and his appetite came back and he went back to work, rejoicing. =left-over habits.= often a state of fatigue is the result of a carried-over habit. one of my patients, a young girl, had several years before been operated on for exophthalmic goiter. this is a disease of the thyroid gland, and is characterized by rapid heart, extreme fatigue, and numerous other symptoms. although this girl's goiter had been removed, the symptoms still persisted. she could not walk nor do even a little work, like wiping a few dishes. i took her down on the beach, let her feel her own pulse and mine and then ran with her on the sand. again i let her feel our pulses and discover for herself that hers had quickened no more than was normal and had slowed down as soon as mine. after a few such lessons, she was convinced that her symptoms were reverberations for which there was no longer any physical cause. another young girl, miss l., had had a similar operation for goiter six years before. since that time she had been virtually bedridden. during the first meal she had at my house her sister sat by her couch because she must not be left alone. by the second meal the sister had gone, and miss l. ate at the table with the other guests. that night she managed to crawl upstairs, with a good deal of assistance and with great terror at the probable results of such an effort. after that, she walked up-stairs alone whenever she had occasion to go to her room. her heart will always be a little rapid and her body will never be very strong, but she now lives a helpful happy life at home and among her friends. in cases like this the exaggeration proves the counterfeit. nobody could have been so down and out _physically_ without dying. the exaggeration secures attention and gives the little satisfaction to the natural desires which are denied expression, and which gain an outlet through habit along the lines previously worn by the real disease. many a person is still suffering from an old pain or an old disability whose cause has long since disappeared, but which is stamped on the mind and believed in as a present reality. since the sensation is as real as ever, it is sometimes very hard to believe that it is not legitimate, but if the person is intelligent, a little explanation and re-education usually suffices. =twenty years an invalid.= mr. s., from ohio, had spent much of his time for twenty years going from one sanatorium to another. there was scarcely a health resort in the country with which he was not familiar. the day he came to me he felt himself completely exhausted by the two-block walk from the car. he explained that he could scarcely listen to what i was saying because his brain was so fagged that concentration was impossible. when asked to read a book, he dramatically exclaimed, "books and i have parted company!" i set him to work reading "dear enemy" but it was not a week before he was devouring the deeper books on psychology, in complete forgetfulness of the pains in his head. playing golf and walking at least six miles every day, he rejoiced in a new sense of strength in his body, which for twenty years he had considered "used up." he is now doing a man-sized job in the business and philanthropic life of his home city. =brain-fag.= this feeling of brain-fag is one of the commonest nervous symptoms; and almost always it is supposed to be the result of intellectual overwork. some people who easily accept the idea that physical work cannot cause nervous breakdown can scarcely give up the deep-rooted notion that intense mental work is harmful. intellectual effort does give rise to fatigue in exactly the same way as does physical exertion, but the body takes care of the waste products of the one just as it does those of the other. du bois says that out of all his nervous cases he has not found one which can be traced to intellectual overwork. i can say the same thing, and i know no case in all the literature of the subject whose symptoms i can believe to be the result of mental labor. the college students who break down are not wrecked by intellectual work. in some cases, one strong factor in their undoing is the strain and readjustment necessary because of the discrepancies between some of their deepest religious beliefs and the truth as they learn it in the class-room. the other factors are merely those which play their part in any neurosis. =re-educating the teacher.= school-teachers are prone to believe themselves worn out from the mental work and the strain of the strenuous life of teaching. many a fine, conscientious teacher has come to me with this story of overwork. but the school-teacher is as easily re-educated as is any one else. i usually begin the process by stating that i taught school myself for ten years and can speak from experience. after i explain that there is no physical reason why the teachers of some cities are fagged out at the end of nine months while those in other cities whose session is longer can hold on for ten months, and stenographers who lead just as strenuous a life manage to exist with only a two-weeks' vacation, they begin to see that perhaps after all they have been fooling themselves by a suggestion, "setting" themselves for just so long and expecting to be done up at the end of the term. many of these same teachers have gone back to their work with a new sense of "enough and to spare" and some of them have written back that they have passed triumphantly through especially trying years with no sense of depletion. in any work, it is the feeling of strain which tells, the emotionalism and feeling sorry for oneself because one has a hard job. it is wonderful what a sense of power comes from the simple idea that we are equal to our tasks. =sudden relief.= the story of mr. v. illustrates professor james's statement that often the fatigue gets worse up to a certain critical point, and then suddenly passes away. mr. v. was another patient who was "physically exhausted." when the rest of "the family" went clamming on the beach, he felt himself too weak for such exertions, so i left him on the sand to hold the bag while the rest of us dug for clams. the minute i turned my back he disappeared. i found him lying flat on his back, resting, behind the bulk-head. i decided that he needed the two-mile walk home and we all set out to walk. "doctor, this is cruel. it is dangerous. my knees can never stand this. i shall be ill!" ran the constant refrain for the first mile. then things went a bit better. toward the last he found, to his absolute astonishment, that the fatigue had entirely rolled away. the last half-mile he accomplished with perfect ease. needless to say, he never again complained of physical exhaustion. =false neuritis.= miss t. was suffering from fatigue and very severe pains in her arms, pains which were supposed to be the result of real neuritis, but which did not correspond to the physiological picture of that disease. a consultation revealed the fact that her love-instinct had been repeatedly stimulated, and then at the last, when it had expected satisfaction, had been disappointed. a discussion of her life, its inner forces, and her future aims helped to pull her together again and give her instinct new outlets. the pains and the fatigue disappeared at once. =something wrong.= these cases are chosen at random and are typical of scores of others. in no single case was the trouble feigned or imaginary or unreal. but in every case it was a mistake. _the sense of loss of muscular power was really a sense of loss of power on the part of the soul._ some inner force was reaching out, reaching out after something which it could never quite attain. as it happened, in every case that i analyzed, the force which felt itself defeated and inadequate was the thwarted instinct of reproduction. like a man pinned to the ground by a stronger force, it felt itself most helpless while struggling the hardest. just as we feel a thrill of fright when we step up in the dark and find no step there, so this instinct had gotten itself ready for a step which was not there. inner repressions or outer circumstances had denied satisfaction and left only an undefined sense that something was wrong. the life-force, feeling itself helpless, limp, tired, had no way of expressing itself except in terms of the body. since expression is itself a relief and an outlet for feeling, the denied desire had seized on suggestions of overwork to explain its sense of weariness, and had symbolized its soul-pain by converting it into a physical pain. the feeling of inadequacy was very real, but it was simply displaced from one part of the personality to another,--from an unknown, inarticulate part to one which was more familiar and which had its own means of expression. =locked-up energy.= we do not know just how the soul can make its pain so intensely real to the body, but we do know that any conviction on the part of the subconscious mind is quickly expressed in the physical machine. a conviction of pain or of powerlessness is very soon converted into a feeling which can scarcely be denied. the mere suggestion that the body is overworked is enough to make it tired. we know, too, that the instincts are the great releasers of energy. so it happens that when our most dynamic instinct--that for the reproduction of the race--is repressed, we lack one of the greatest sources of usable energy. the energy is there, but it is not accessible. inhibited and locked away, it is not fed into the engine, and we feel exactly as though it were _nil_. despite its name, the disease neurasthenia does not signify a real asthenia or weakness. rather, it is a disorder in which there is plenty of energy that has somehow been temporarily misplaced. then, too, we must remember that under the depressing influence of chronic fear, not quite so much energy is stored away as would otherwise be. all the bodily functions are slowed down; food is not so completely assimilated, the heart-beat is weakened, the breathing is more shallow, and fatigue products are more slowly eliminated. as du bois says, "an emotion tires the organism more than the most intense physical or intellectual work." =avoid the rest-cure.= it is a healthful sign that the rest-cure is fast going out of style. wherever it has helped a nervous patient, the real curative agent has been the personality of the doctor and the patient's faith in him. the whole theory was based on ignorance of the cause of nerves. people suffering from "nervous exhaustion" are likely to be just as "tired" after a month in bed as they were before. why not? physical fatigue is quickly remedied, and what can rest do after that? what possible effect can rest have on the fatigue of a discouraged instinct? since the best releaser of energy is enthusiasm, don't try to get that by lying around in bed or playing checkers at a health resort. summary if you are chronically and perpetually fatigued, or if you tire more easily than the other people you know, consult a competent physician and let him look you over. if he tells you that you have neither tuberculosis, heart trouble, bright's disease, nor any other demonstrable disease, that you are physically fit and "merely nervous," give yourself a good shake and commit the following paragraphs to memory. a catechism for the weary one what? q. what is fatigue? a. it is a chemical condition resulting from effort that is very recent. q. what else

which the ban is lifted_ dietary taboos misunderstood stomachs =modern improvements.= most people have heard the story of the little girl who wanted to know what made her hair snap. after she had been informed that there was probably electricity in her hair, she sat quiet for a few minutes and then exclaimed: "our family has all the modern improvements! i have electricity in my hair and grandma has gas on her stomach!" judged by this standard many american families are well abreast of the times; and if we include among the modern improvements not only gas on the stomach but also nervous dyspepsia, acid stomach, indigestion, sick-headache, and biliousness, we must conclude that a good proportion of the population is both modern and improved. despite all this the stomach is one of the best-equipped mechanisms in the world. it, at least, is not modern. after their age-long development the organs of the body are remarkably standardized and adapted to the work required of them. it is safe to say that ninety per cent. of all so-called "stomach trouble" is due not to any inherent weakness of the organ itself but to a misunderstanding between the stomach and its owner. =organic trouble.= unfortunately, there are a few real organic causes for trouble. there are a few cancers of the stomach and a certain number of ulcers. but if the patients whom i have seen are in any way typical, the ulcers that really are cannot compare in number with the ulcers that are supposed to be. patients go to physicians with so many tales of digestive distress that even the best doctors are fooled unless they are especially alert to the ways of "nerves." they must find some explanation for all the various functional disturbances which the patients report, and as they are in the habit of taking only the body into account, they find the diagnosis of stomach ulcer as satisfactory as any. there is, of course, such a thing as an enlarged or sagging stomach. but it is only in the rarest of cases that such a condition leads to any functional disturbances unless complicated by suggestion. in most cases a person can go about his business as happily as ever unless he gets the idea that ptosis must inevitably lead to pain and discomfort. confusion sometimes arises when the stomach is blamed for disturbances which originate elsewhere. one day a very sick-looking girl came to me with eager expectation written all over her face. her stomach was misbehaving and she had heard that i could cure nervous indigestion. it needed little more than a glance to know that she was suffering from organic heart trouble. a boy of sixteen had been taking a stomach-tonic for three months, but the thin, wiry pulse pointed to a different ailment. his digestive disturbances were merely the echo of an organic disease of the kidneys. when the body is burdened by disease, it may have little energy left for digesting food, but in that case the trouble must be sought in other quarters than the stomach. aside from a few organic difficulties, there is almost no real disease of the stomach. its misdoings are not matters of food and chemistry, muscle-power and nerve supply, but are the end results of slips in the mental and emotional life of its owner. =fads dynamogenic.= what is it that gives the impetus to fads about eating, or about religious belief? are they advocated by the individual whose libido is finding abundant expression in the natural channels of business and family life, or by his less fortunate brother who can gain a sense of power only by means of some unaccustomed idea? william james says: this leads me to say a word about ideas considered as dynamogenic agents or stimuli for unlocking what would otherwise be unused reservoirs of individual power.... in general, whether a given idea shall be a live idea depends more on the person into whose mind it is injected than on the idea itself. which is the suggestive idea for this person and which for that one? mr. fletcher's disciples regenerate themselves by the idea (and the fact) that they are chewing and re-chewing and super-chewing their food. dr. dewey's pupils regenerate themselves by going without their breakfast--a fact, but also an ascetic idea. not every one can use these ideas with the same success. because it is so adaptable and sturdy, the stomach lends itself readily to these devices for gaining self-expression; but the danger lies in bringing the process of digestion into conscious attention which interferes with automatic functioning. still further, the disregard of physiological chemistry is likely to deprive the body of food-stuffs which it requires. the average person is too sensible to be carried off his feet by the enthusiasm of the health-crank, but as most of us are likely to pick up a few false notions, it may be well to be armed with the simple principles of food chemistry in order to combat the fads which so easily beset us and to know why we are right when we insist on eating three regular meals of the mixed and varied diet which has proved best for the race through so many years of trial and experience. what we need to eat =the essence of dietetics.= to the layman the average discussion of food principles is, to say the least, confusing. dealing largely, as it does, with unfamiliar terms like carbohydrate and hydrocarbon and calories, it is hard to translate into the terms of the potatoes left over from dinner and the vegetables we can afford to buy. but the practical deductions are not at all difficult to understand. boiled down to their simplest terms, the essential principles may be stated in a few sentences. the body must secure from the food that we eat, tissue for its cells, energy for immediate use or to be stored for emergency, mineral salts, vitamins, water and a certain bulk from fruits and vegetables,--this latter to aid in the elimination of waste matter. food for repairing bodily tissue is called protein and is secured from meat, eggs, milk, and certain vegetables, notably peas. fuel for heat and energy is in two forms--carbohydrate (starch and sugar) and fat. we get sugar from sugar-cane and beets, and from syrups, fruit, and honey. starch is furnished from flour products--mainly bread--from rice, potatoes, macaroni, tapioca, and many vegetables. fats come from milk and butter, from nuts, from meat-fat--bacon, lard and suet--and from vegetable oils. the mineral salts are obtained mainly from fruit and vegetables, which also provide certain mysterious vitamins necessary for health, but as yet not well understood. =what the market affords.= the moral from all this is plain. the human body needs all the foods which are ordinarily served on the table. whenever, through fad or through fear, we leave out of our diet any standard food, we are running a risk of cutting the body down on some element which it needs. they say that variety is the spice of life. in the matter of food it is more than that, it is the essence of life. eat everything that the market affords and you will be sure to be well nourished. if you leave out meat you will make your body work overtime to secure enough tissue material from other foods. if you leave out white bread, you will lose one of the greatest sources of energy. if you leave out tomatoes and cucumbers and strawberries, you deprive your body of the salts and vitamins which are essential. =a simple rule.= there is one point that is good to remember. the average person needs twice as much starch as he needs of protein and fat together. that is, if he needs four parts of protein and three of fat, he ought to eat about fourteen parts of starch. this does not mean that we need to bother ourselves with troublesome tables of what to eat, but only to keep in mind in a general way that we need more bread and potatoes than we do meat and eggs. the body does not have to rebuild itself every day. it is probable that a good many people eat too much protein food. if a man is doing hearty work he must have a good supply of meat, but the average person needs only a moderate amount. here again, the habits of the more intelligent families are likely to come pretty near the dictates of science. =for the children.= the mother of a family ought to know that the children need plenty of bread, butter, and milk. despite all the notions to the contrary, good well-baked white bread is neither indigestible nor constipating. it is indeed the staff of life. two large slices should form the background of every meal, unless there is an extraordinary amount of other starchy food or unless the person is too fat. milk-fat (from whole milk, cream, and butter) is by far the best fat for children. besides fat, it furnishes a certain growth-principle necessary for development. as the dairyman cannot raise good calves on skimmed milk, so we cannot raise robust children without plenty of butter and milk. the pity of it is that poor people are forced to try! milk is also the best protein for children, whose kidneys may be overstrained by trying to care for the waste matter from an excessive quantity of eggs and meat. bread and butter, milk, fruit, vegetables, and sugar in ample quantities and meat and eggs in moderate quantities are pretty sure to make the kind of children we want. above all things, let us train them not to be afraid of normal amounts of any regular food or of any combination of foods. =the fear of mixtures.= there are many people who can without flinching face almost any single food, but who quail before mixtures. perhaps there is no notion which is more firmly entrenched in the popular mind than this fear of certain food-combinations, acquired largely from the advertisements of certain so-called "food specialists." the most persistent idea is the fear of acid and milk. it is interesting to watch the new people when they first come to my table. confronted with grape-fruit and cream at the same meal, or oranges and milk, or cucumbers and milk, they eat under protest, in consternation over the disastrous results that are sure to follow. out of all these scores of people, many of whom are supposed to have weak stomachs, i have never had one case of indigestion from such a combination. when a person knows that the stomach juices themselves include hydrochloric acid which is far more acid than any orange or grapefruit, that the milk curdles as soon as it reaches the stomach, and that it must curdle if it is to be digested, he has to be very "set" indeed if he is to cling to any remnant of fear. of course to say that the stomach is well prepared chemically, muscularly, and by its nerve supply to handle any combination of ordinary food in ordinary amounts is not the same thing as saying that we may devour with impunity any amount of anything. it is a good thing for every one to know when he has reached his limit, and a person with organic heart disease should avoid eating large quantities at one time, or when he is extraordinarily fatigued or emotionally disturbed, lest at such a time he may put a fatal strain on the pneumogastric nerve that controls both stomach and heart. the fear of certain foods =physical idiosyncrasies.= most of our false fears on food subjects come from some tradition--either a social tradition or a little private, pet tradition of one's own. some one once was ill after eating strawberries and cream. what more natural than to look back to those little curdles in the dish and to start the tradition that such mixtures are dangerous? the worst of it is that the taboo habit is very likely to grow. one after another, innocent foods are thrown out until one wonders what is left. a patient of mine, mr. g., told me that he had a short time before gone to a physician with a tale of woe about his sour stomach. "what are you eating?" asked the doctor. "bran crackers and prunes." "then," said the learned doctor, "you will have to cut out the prunes!" needless to say, this man ate everything at my table, and flourished accordingly. there may be such a thing as physical idiosyncrasies for certain foods. i have often heard of them, but i have never seen one. i have often challenged my patients to show me some of the "spells" which they say invariably follow the eating of certain foods, but i have almost never been given an exhibition. the man who couldn't eat eggs did throw up once, but he couldn't do it a second time. many people have threatened to break out with hives after strawberries. one woman triumphantly brought me what looked like a nice eruption, but which proved to be the after-results of a hungry flea! after that she ate strawberries,--without the flea and without the hives. =not miracles but ideas.= conversions on food subjects are so common at my table that i should have difficulty in remembering the individual stories. scores of them run together in my mind and make a sort of composite narrative something like this: "oh, no, thank you, i don't eat this. you really must excuse me. i have tried many times and it is invariably disastrous." then a reluctant yielding and a day or two later some talk about miracles. "it really is wonderful. i don't understand," etc. experiences like these only go to show the power of the subconscious mind, both in building up wrong habit-reactions and in quickly substituting healthy ones, once the false idea is removed. among my stomach-patients there were two men, brothers-in-law, immigrants from the austrian tyrol, and now resident in one of the cow-boy states. leonardo spoke little english, and though giovanni understood a very little, he spoke only italian. several years before i knew them, giovanni had developed a severe case of stomach trouble and had finally gone to a medical center for operation. the disturbance, however, was not relieved by the operation and before long his brother-in-law fell into the same kind of trouble. for several years the two had spent much of their time dieting, vomiting, and worrying over their sour stomachs. giovanni finally became so ill that his sick-benefit society had actually assessed its members to pay for his funeral expenses. about this time a business man of their town, impressed by the cure of a former patient who had made a quick recovery after seven years of invalidism, persuaded the two men to take their little savings and come to california to be under my care. the evening meal and breakfast went smoothly enough, although the menu included articles which they had been taught to avoid. however, as i left the house on a necessary absence soon after breakfast, i saw leonardo weeping in the garden and giovanni spitting up his breakfast, out at the entrance gate. on my return, i found one of "the family" literally sitting on the coat-tails of leonardo, while giovanni hovered at a distance, safe from capture. leonardo upbraided me bitterly for having undone all the gain they had made in the long months of rigid dieting, for now the vomiting had returned, because they had eaten sugar on their oatmeal at breakfast! i made leonardo drink an egg-nog, took him into the consultation-room and held my hand on his knee to keep him in his chair, while explaining to him as best i could the physiologic action of the hydrochloric acid on the digestive juice, which he feared as a sour stomach, the sign of indigestion. during the conversation i said, "i suppose giovanni imitated you in this mistaken fear about your health." the reply was, "no, i got it off him!" nearly two hours later he exclaimed in astonishment: "why, that milk hasn't come up! maybe i am cured!" "of course you are cured," i answered; "there never was anything really the matter with your stomach, so you are cured as soon as you think you are." later giovanni was inveigled into the house by the promise that he would have to eat nothing more than milk soup. all was smooth sailing after this. for my own part i feared for the permanency of the cure, for they were returning to the old environment. but more than three years have passed, and grateful letters still come telling of their continued health. another patient, a teacher of domestic science in a big eastern university, had lived on skimmed milk and lime-water from easter to thanksgiving. several attempts to enlarge the dietary by adding cream or white of egg had only served to increase the sense of discomfort. finding nothing in the history of the case to warrant a diagnosis of organic disease of the stomach, i served her plate with the regular dinner, bidding her have no hesitancy even over the pork chops and potato chips. she gained nine pounds in weight the first week, and in two and a half months was forty pounds to the good. =when re-education failed.= but there is one patient who has had to have his lesson repeated at intervals. this man laughingly calls himself a disgrace to his doctor because he is a "repeater." his story illustrates the power of an autosuggestion and the disastrous effect of attention to a physiological function. when mr. t. came first to me he weighed only 120 pounds, although he is over six feet tall and of large frame. from the age of sixteen he had followed fads in eating and thought he had a weak stomach. i treated his "weak stomach" to everything there was in the market, including mince-pies, cabbage, cheese, and all the other so-called indigestibles. he gained 16-1/2 pounds the first week and 31 pounds in five weeks. one would think that the idea about the weak stomach would have died a natural death, but it did not. again and again he came back to me like a living skeleton, the last time weighing only 105 pounds, and again and again he has gone back to his home in the middle west plump and well. twice while he was at home he underwent unnecessary operations, once for an ulcer that was not there and once for supposed chronic spasm of the pylorus. needless to say, the operations did not help. you cannot cut out an idea with a knife. neither can you wash it out with a stomach-pump; else would mr. t. long ago have been cured! this particular idea of his seems to be proof against all my best efforts at re-education. psycho-analysis is impracticable, partly because of the duration of the habit of repression, but the history, and certain symbolic symptoms, indicate the freudian mechanisms at work. all i can do is to feed him up, bully him along, and keep him from starving to death. just now he is doing very well at home, although he has moved to california so as not to be too far away from "the miracle-worker." if mr. t.'s case had been typical, i should long ago have lost my faith in psychotherapy. keeping people from starving is worth while, but is less satisfactory than curing them of what ails them. the nervous patient who has a relapse is no credit to his doctor. it is only when the origin of his trouble is not removed that the bond of transference tends to become permanent. the neurotic who is well only while under the influence of his physician is still a neurotic. however, as most people's complexes are neither so deeply buried nor so obstinate as this, a simple explanation or a single demonstration is usually enough to loose the fettering hold of old misconceptions. common ailments ="gas on the stomach."= we all know people who suffer from "gas." indeed, very few of us escape an occasional desire to belch after a hearty meal. but the person with nervous indigestion rolls out the "gas" with such force that the noise can sometimes be heard all over the house. he may keep this up for hours at a time, under the conviction that he is freeing himself from the products of fermenting food. he may exhibit a well-bloated stomach as proof of the disastrous effect of certain articles of diet. the gas and the bloating are supposed to be the sign and the seal of indigestion, a positive evidence that undigested food is fermenting in the stomach. but what is fermentation? it is, necessarily, a question of the growth of bacteria and is a process which we may easily watch in our own kitchens. bread rises when the yeast-cells have multiplied and acted on the starch of the flour, producing enough gas to raise the whole mass. potatoes ferment because bacteria have multiplied within them. canned fruit blows up because enough bacteria have developed inside to produce sufficient gas to blow open the can. every housewife knows that it takes time for each of these processes. bread has to stand several hours before it will rise; potatoes do not ferment under twelve hours, and canned fruit is not considered safe from the fermenting process under three days. evidently there is some mistake when a person begins to belch forth "gas" within an hour or two after a meal. as a matter of fact, it is not gas at all but merely air that is swallowed with the food or that was present in the empty stomach. when the food enters the stomach it necessarily displaces air, which normally comes out automatically and noiselessly. but if, through fear or attention, a certain set of muscles contract, the pent-up air may come forth awkwardly and noisily or it may stay imprisoned until we take measures to let it out. a hearty laugh is as good as anything, but if that cannot be managed, we may have to resort to a cup of hot water which gives the stomach a slap and makes it let go. two belches are enough to relieve the pressure. after that we merely go on swallowing air and letting it out again, a habit both awkward and useless. if the emotion which ties the muscle-knot is very intense, and the stomach refuses to let go under ordinary measures, the pain may be severe. but a quantity of hot water or a dose of ipecac is sure to relieve the situation. if the person is able to give himself a good moral slap and relax his unruly muscles, he reaches the same end by a much pleasanter road. some people are fond of the popular remedy of hot water and soda. their faith in its efficacy is likely to be increased by the good display of gas which is sure to follow. as any cook knows, soda and acid always fizz. the soda is broken up by the hydrochloric acid of the stomach and forms salt and carbon dioxid, a gas. however, as the avowed aim of the remedy is the relief of gas rather than its manufacture, and as the soda uses up the hydrochloric acid needed in digestion, the practice cannot be recommended as reasonable. =gastritis.= i once knew a woman who went to a big city to consult a fashionable doctor. when she returned she told with great satisfaction that the doctor had pronounced her case gastritis. "it must be true," she added, "because i have so much gas on my stomach!" the diagnosis of gastritis used to be very common. the ending _itis_ means inflammation,--gastritis, enteritis, colitis, each meaning inflammation of the corresponding organ. an inflammation implies an irritant. there can be no kind of _itis_ without the presence of something which irritates the membrane of the affected part. if we get unusual and irritating bacteria in some spoiled food, we are likely to have an acute inflammation until the offending bacteria are expelled. but an inflammation of this kind never lasts. people who have had ptomaine poisoning sometimes assert that they are afterwards susceptible to poisoning by the kind of food which first made them ill. such a susceptibility is not so much a hold-over effect from the poison as a hold-over fear which tends to repeat the physical reaction whenever that food is eaten. i, myself, have had ptomaine poisoning from canned salmon, but i have never since had any trouble about eating salmon. =sour stomach.= sometimes when a person lies down an hour or so after a meal, some of the contents of his stomach comes up in his throat. then if he be ignorant of physiology, he may be very much alarmed because his stomach is "sour." not knowing that he would have far greater cause for alarm if his stomach were _not_ sour, he may, if the idea is interesting to him, begin to restrict his diet, to take digestive tablets, and to develop a regular case of nervous dyspepsia. sometimes when the specialists measure the amount of hydrochloric acid in the stomach, they do find too much or too little acid; but this merely means that an emotion has made the glands work overtime or has stopped their action for a little while. the functions of the body are so very, very old that there is little likelihood of permanent disturbance. =biliousness.= the stomach is not the only part of the body concerning which we lack proper confidence. next to it the liver is the most maligned organ in the whole body. although the liver is about as likely to be upset in its process of secreting bile as the ocean is likely to be lacking in salt, many an intelligent person labels every little disturbance "biliousness" and lays it at the door of his faithful, dependable liver. as a matter of fact, the liver is liable to injury from virtually but three sources--alcohol, bacterial infection, and cancer--and even a liver hardened by alcohol goes on secreting bile as usual. the patient dies of dropsy but not of "liver complaint." some people act as if they thought bile were a poison. on the contrary, it is a very useful digestant; it aids in keeping down the number of harmful bacteria and helps to carry the food from intestines to blood. every day the liver manufactures at least a pint of this important fluid. the body uses what it needs and stores the surplus for reserve in the gall-bladder. the flow is continuous and, despite all appearances to the contrary, there is no such thing as a torpid or an over-active liver. it is true that after a "bilious" person has vomited for a few minutes he is likely to throw up a certain amount of bile, which is supposed to have been lying in his stomach and causing the nausea. in fact, however, this bile is merely a part of the usual supply stored away in the gall-bladder. by the very act of retching, the bile is forced out of the bile channels into the stomach and thence up into the mouth. anybody can throw up bile at any time if he only tries hard enough. one of the favorite habits of certain people is the taking of calomel and salts. after such a dose they view with satisfaction the green character of the stools and conclude that they have rid themselves of a great amount of harmful matter. as a matter of fact, the greater part of the coloring in the stools is from the calomel itself, changed in the intestines from one salt of mercury to another. any excess bile is the result of the irritating action of the calomel on the intestinal wall, an irritation which makes the bowel hurry to cast out this foreign substance without waiting for the bile to be absorbed as usual. a patient once told me that he had bought medicine from a street fakir and by his direction had followed it with a dose of salts. he saved the bowel movement, washed it in a sieve, and discovered a great number of "gall-stones," which the medicine had so effectively washed from his system. he was much astonished when i told him that his gall-stones were merely pieces of soap. he did not know that everybody manufactures soap in his body every day, and that by taking an extra quantity of oil in the shape of the fakir's medicine and an extra quantity of potash in the salts, he had merely augmented a normal physiological process. the supposed action of calomel belongs to the same class of phenomena, and has no slightest effect on the liver or on real gall-stones, which are the precipitate of bile-salts in the gall-bladder, and which cannot be reached by any medicine. if the popular notions about biliousness are ill founded, what then causes the disturbances which undoubtedly do occur and which show themselves in attacks of nausea or sick headache? the answer can be given in a word of four letters; a coated tongue, a bilious attack and a sick headache are all the outcome of a mood. stocks have gone down or the wife is cranky or the neighbors are hateful. adrenalin and thyroid secretions are poured out as the result of emotion; digestion is stopped, circulation disturbed, and the whole apparatus thrown out of gear. =sick-headache.= sick-headache is primarily a circulatory disturbance; and although the disturbance may have been inaugurated by some chemical unbalance, the sum total of the force that makes a sick-headache is emotional. the emotion, of course, need not be conscious in order to be effective. if we picture the arteries all over the body as being supplied with, among other things, a wall of circular muscles, and then imagine messages of emotion being flashed to the nerves controlling this muscle wall, we may get an idea of what happens just before a sick-headache. some parts of the arteries contract too much and other parts relax. the arteries to the head tighten up at the extremities and become loose lower down. the force of the blood-stream against the constricted portion can hardly fail to cause pain. the sick part of the headache is merely a sympathetic strike of the nerves which control circulation and stomach. the moral of all this is plain. if a sick-headache is the result of an emotional spasm of the blood-vessels, the obvious cure is a change of the emotion. some people manage it by going to a party or a picnic, others by ignoring the symptoms and keeping on with their work. a woman physician whom i know was in the midst of a violent headache when called out on an obstetrical case. she felt sorry for herself, but went on the case. in the strenuous work which followed, she quite forgot the headache, which disappeared as if by magic. sometimes it happens that a headache recurs periodically or at regular intervals. it is easy to see that in such cases the exciting cause is fear and expectation. at some time in the past, headaches have occurred at an interval of, say, fourteen days; as the next fourteenth day approaches the sufferer says to himself: "it is about time for another headache. i am afraid it will come to-morrow," and of course it comes. one man told me that if he ate sunday-night supper he inevitably had a headache on monday morning. we were about to sit down to a simple sunday supper and he refused very positively to join us. i told him he could stay all night and that i would take care of him if the monday sickness appeared. he accepted my challenge but was unable to produce a headache. in fact, he felt so unusually flourishing the next morning that he insisted on frying the bacon for my entire family. that was the end of the monday headaches. =a few examples.= as sick-headache has always been considered a rather stubborn difficulty, not amenable to most forms of treatment, it may be well to cite a few cases which were helped by educational methods. a patient came home from a walk one day and announced that he was going to bed. when questioned, be said: "i am tired and i have a sick-headache. isn't it logical to go to bed?" to which i answered that it would be far more logical to put some food into his stomach and change the circulation than to lie in bed and think about his pain. this man was completely cured. i have had patients throw up one meal, and very rarely two, but i have never had to supply more than three meals at a time. the waste of food i consider amply justified by the benefit to the patient. there once came to me an elderly woman, the wife of a poor minister. she was suffering from attacks of nausea, which recurred every five to ten days with intense pain through the eyes, and with photo-phobia or fear of light. i found that she had by dint of heroic efforts raised a large and promising family on the salary of an itinerant minister--from four hundred to six hundred a year! all the time she had been feeling sorry for herself because her husband did not appreciate her. one day, after reading one of his letters which seemed to show an utter lack of appreciation of all that she was doing, she fell down in the field beside her plow, paralyzed. from that time on she had been more or less of an invalid, continually nursing her grudge and complaining that she ought not to have been made to bear so many children. after i had heard this plaint over and over for about a week, i said: "perhaps you ought not to have had that little daughter, the little ewe-lamb. maybe she was one too many." "oh, no," came the quick response. "i couldn't have spared _her_." then i went down the line of the fine stalwart sons. perhaps she could have spared john or tom or fred? finally she saw the whole matter in a different light,--saw herself as a queen among women, the mother of such a family. as to the husband, i tried to show her that she was not very clever to live with a man all those years without discovering that he was not likely to change. "you can't change him but you can change your reaction to him. if something keeps hurting your hand, you don't keep on being sore. you grow callous. isn't it about time you grew a moral callous, too?" i put her on the roof to sleep, on account of her fear of light. only once did she start a headache, which i quickly nipped in the bud by making her get up and dress. she had come to stay "three months or four,--if i get along well." at the end of four weeks she left, an apparently well woman. the last i heard of her she was stumping the state for temperance, the oldest of an automobile party of speakers, and the sturdiest physically. with the emotional grievance, disappeared also the physical effects in stomach and head. miss s., a very brilliant woman, ambitious to make the most of her life, had been shelved for twenty-five years because of violent sick-headaches which made it impossible for her to undertake any kind of work. she had not been able to read a half-hour a day without bringing on a terrible headache. i insisted on her reading, and very soon she was so deep in psychological literature that i had difficulty in making her go to bed at all. after learning the cause of her headaches and gaining greater emotional control, she succeeded so well in freeing herself from the old habit, that she now leads the busiest kind of useful life with only an occasional headache, perhaps once in six months. a certain minister suffered constantly from a dull pain in his head, besides having violent headaches every few days. he started in to have a bad spell the day after his arrival at my house. as i was going out of the door, he caught my sleeve. "doctor," he said, "would it be bad manners to run away?" "manners?" i answered. "they don't count, but morals, yes." he stayed--and that was his last bad headache. both chronic and periodic pains disappeared for good. one woman who had suffered from bad headaches for eighteen years lost them completely under a process of re-education. on the other hand, i have had patients who were not helped at all. the principles held good in their cases, but they were simply not able to lose the old habit of tightening up the body under emotion. =hysterical nausea.= sometimes nausea is merely the physical symbol of a subconscious moral disgust. we have already told the stories of "the woman with the nausea" (chapter v) and of mrs. y. (chapter vii). these cases are typical of many others. their bodies were perfectly normal, and when, through psycho-analysis and re-education, they were helped to make over their childish attitudes toward the sex-life, the nausea disappeared. =loss of appetite.= a nervous patient with a good appetite is "the exception that proves the rule." the neurotic is usually under weight and often complains that he feels satiated almost as soon as he begins to eat. loss of appetite may, of course, mean that the body is busy combating toxins in the blood, but in a nervous person it usually means a symbolic loss of appetite for something in life, a struggle of the personality against something for which he has "no stomach." psycho-analysis often reveals the source of the trouble, and a little bullying helps along the good work. by simply taking away a harmful means of expression, we may often force the subconscious mind to find a better language. summary since the stomach seems to be an organ which is much better fitted to care for food than to care for a depressing emotion or a false idea, it seems far more sensible to change our minds than to keep enlarging our list of eatables which are taboo. and since most indigestion is in very truth nothing more nor less than an emotional disturbance, worked up by fear, anger, discontent, worry, ignorance, suggestion, attention to bodily functions which are meant to be ignored, love of notice and the conversion of moral distress into physical distress, the best diet list which can be furnished to mr. everyman in search of health must read something like this: menu monday, tuesday, wednesday, thursday, friday, saturday, sunday a calm spirit plenty of good cheer a varied diet commonsense good cooking judicious neglect of symptoms forgetfulness of the digestive process a little accurate knowledge a determination to be like folks chapter xi _in which we relearn an old trick_ the bugaboo of constipation popular superstitions in line with the taboos connected with the taking of food are the ceremonials attendant upon its elimination. taking anxious thought about functions well established by nature is a feature of conversion-hysteria, the displacement of emotional desire from its psychic realm into symbolic physical expression. whatever other symptoms nervous people may manifest, they are almost sure to be troubled with chronic constipation. it is true that there are many constipated people who do not seem to be nervous and who resent being classed among the neurotics. everybody knows that the occasional individual who has difficulty in swallowing his food is nervous and that the, trouble lies not in the muscles of his throat but in the ideas of his mind. but very few people seem to realize that the more common individual who makes hard work of that other simple process--elimination of his intestinal waste matter--is suffering from the same kind of disturbance and giving way to a nervous trick. when all the facts are in, the constipated person will have hard work to clear himself of at least one count on the charge of nerves. =an oft-told tale.= sooner or later, then, the neurotic, whether he calls himself a neurotic or not, is very likely to begin worrying over his diet or his sedentary occupation. he imagines himself the victim of autointoxication, afflicted with paralysis of the colon or dearth of intestinal secretions. he leaves off eating white bread, berries, cheese, chocolate, and many another innocent food, and insists on a diet of bran-biscuit, flaxseed breakfast-foods, prunes, spinach, cream, and olive-oil with doses of mineral oil between meals. in all probability, he begins a course of massage or he starts to take extra long walks and to exercise night and morning, pulling his knees up to his chin and touching his fingers to his toes. when all these measures fail, he gives in to the morning enema or the nightly pill, in imminent danger of succumbing to a life-long habit. the truth about constipation =what the colon is for.= it is well, then to have a fair understanding of the structure and purpose of our intestinal machinery. contrary to general opinion, the intestines are not a dumping-ground but a digestive organ. after the food is partly digested in the stomach, it passes through a twenty-two foot tube (the small intestine) into a five-foot tube (the large intestine or colon) where digestion is completed, the nutriment is absorbed, and the waste matter is passed on and out through the rectum. as the food passes along the colon, pushed slowly ahead by the peristaltic wave, or rhythmic muscular contractions of the intestinal wall, it is seized upon by the four hundred varieties of friendly bacteria which inhabit the intestines of every healthy person, and is changed into a form which the body can assimilate. digestion in the stomach and small intestine is carried on by means of certain digestive juices, but in the large intestine it is the bacteria which do the work. without them we could not live. around the colon is a thick network of little blood vessels, all of which lead straight to the liver, the storehouse of the body. after the food is fully digested, it is passed through the thin intestinal wall into these tiny vessels and carried away to liver and muscles for storage or for immediate use. this process of absorption is carried on throughout the whole length of the colon. not until the very end of the intestine is reached is all the nutrition abstracted. the bowel-content can properly be called waste matter only after it has reached the rectum or pouch at the lower end of the colon. even then, this waste matter is not poison, but merely indigestible material which the body cannot handle. =food, not poison.= the colon is not a cesspool but a digestive and assimilating organ. its content is not poison but food. active elimination is important not so much because delay causes autointoxication or poisoning as because too large a mass is hard to manage and irritates the intestinal wall. the problem is not so much one of toxicology as of simple mechanics. if nature had put within the body five feet of tubing which could easily become a cesspool and a breeder of poison, it is not at all likely that she would have laid alongside an elaborate system of blood vessels leading not out to the kidneys but into the storehouse of the liver; and if civilized man's changed manner of living had so upset nature's plans as easily to transform his internal machinery into a chronic source of danger, we may be sure that he would long ago have gone the way of the unfit and succumbed to his own poisons. =possible invasions.= it is true that the intestinal tract, like the rest of the body, is open to attack by harmful bacteria. but in a great majority of cases, these enemy bacteria are either quickly destroyed by the beneficent microbes within or are immediately cast out as unfit. any germs irritating to the intestinal wall cause the mucous membrane to produce an unusual flow of mucus which washes away the offending bacteria in what we call a diarrhea.[52] [footnote 52: if the invading army proves obstinate and the diarrhea continues a day or so, it is wise to assist nature by a dose of castor-oil, which gives an additional insult to the intestinal wall, spurs it on to a desperate effort, and hastens the cleansing process. in severe cases the more promptly the castor-oil is administered the better. such emergency measures are very different from the habitual use of insulting drugs.] sometimes the wrong kind of bacteria do persist, causing anemia, rheumatism, sciatica, or neuritis. when these disorders are not the result of infection from teeth, tonsils, or other sources of poison, but are really caused by intestinal bacteria, i have found that a diet of buttermilk (lactic acid bacteria), with turnip-tops or spinach to supply the necessary mineral salts, often succeeds in planting the right bacteria and driving out the disturbing ones. these disorders are invasions from without, like tuberculosis or malaria, and are as likely to attack the person with easy bowel movements as the one with the most chronic constipation. =autointoxication.= a good deal of the talk about autointoxication is just talk. it sounds well and affords an easy explanation for all sorts of ills, but in a large majority of cases the diagnosis can hardly be substantiated. uninformed writers of newspaper articles on the care of the body, or purveyors of purgatives or apparatus for internal baths are fond of dilating on the "foulness of the colon" as a leading cause of disease. as a rule, they advise either a strict diet, some kind of cathartic, or an elaborate process of washing out the colon to clear the body of its terrible accumulation of poisons. =cathartics and enemas.= he who makes a practice of flushing out his intestinal tract with high enemas and internal baths is like a person who eats a good dinner and then proceeds to wash out his stomach. in the mistaken idea that he is making himself clean, he is washing what was never intended to be washed and robbing the body of the nutrition which it needs. and the man who persists in the pill habit is making a worse mistake, adding insult to injury and forcing the mucous membrane to toughen itself against such malicious attacks. =cathartics and operations.= even in emergencies, the use of purgatives as a routine measure is happily decreasing year by year. for many years i have deplored the use of purgatives before and after operations. that other practitioners are coming to the same conclusion is witnessed by a number of papers recently read in medical societies condemning purgation at the time of operation. among the most favorably received papers of the california medical societies have been one by emmet l. rixford, surgeon of the stanford university medical college, read before the southern california medical society at los angeles december 8, 1916, and one by w.d. alvarez at the california medical society, del monte, 1918,--both condemning the use of purgatives as a routine measure before operations. an article entitled the "use and abuse of cathartics" in the "journal of the american medical association" admirably summarizes the disadvantages of purgation at such a time.[53] [footnote 53: "1 danger of dissemination of infection throughout the peritoneal cavity, in case localized infection exists. "2 increased absorption of toxins and greater bacterial activity by reason of the fact that undigested food has been carried down into the colon to serve as pabulum for bacteria, and that liquid feces form a better culture medium than solid feces. "3 increased distention of the intestine with gas and fluid, when it should be empty.... "4 psychic and physical weakness produced by dehydration of the body, disturbance in the salt balance of the system, and the loss of sleep occasioned by the frequent purging during the night preceding the operation. as oliver wendell holmes says: 'if it were known that a prize fighter were to have a drastic purgative administered two or three days before a contest, no one will question that it would affect the betting on his side unfavorably. if this be true for a powerful man in perfect health, how much more true must it be of the sick man battling for life.' "5 increase in postoperative distress and danger: thirst, gas pains, and even ileus...."--_journal of american medical association_, vol. 73, no. 17, p. 1285, oct. 25. 1919.] four years ago i was called to a near-by city to see a former patient who two days before had had a minor operation,--removal of a cyst of the breast. she was dazed, almost in a state of surgical shock and very near collapse. i found that she had been put through the usual course of purgation before operation and starvation afterward, and i diagnosed her condition as a state bordering on acidosis, or lowering of the alkaline salts of the body. i ordered food at once. she rallied and recovered. a few months later this same woman had to undergo a much more serious operation for multiple fibroids of the uterus and removal of the appendix. this time i advised the surgeon against the use of any purgative, and he took my remarks so seriously that he did not even allow an enema to be given. this time the patient showed no signs of exhaustion and had very few gas pains. i firmly believe that the day will soon come when a patient under operation, or a patient after childbirth, will no longer be depleted by a weakening and dehydrating cathartic and by a period of starvation, at a time when he needs all the energy he can summon. =cathartics and childbirth.= the article referred to in the "journal of the american medical association" cites the experiences of dr. r. mcpherson of the lying-in hospital of new york, "who showed that the routine purgation after confinement is not only useless but harmful. of 322 women who were not purged, only three had fever (and one of them a mammary abscess); most of them had normal bowel movements and those who did not were given an enema every third day. of 322 women who were delivered by the same technique and the same operators but were purged in the usual routine manner, twenty-eight had some fever." this experience of one physician is corroborated by that of others who find that the more we tamper with the natural functions in time of stress the harder do we make the recuperative process. there are certainly times when catharsis is necessary but "one thing is certain, the day for routine purgation is past."[54] even in emergencies we need to know why we administer cathartics and in chronic cases we may be sure that they are always a mistake. [footnote 54: ibid, p. 1286.] ="an old trick."= before we make a practice of interfering with nature's processes, it is well to remember how old and stable those processes are. as long as there has been the taking in of food, there has been also the casting out of waste matter. the sea-anemone closes in on the little mollusk that floats against its waving petals, assimilates what it can and rejects the rest. in the long line from sea-anemone to man, this automatic process of elimination has gone on without a hitch, adapting itself with perfect success to the changing habits of the varying types of life. so old a process is not easily upset. and, be it noted, in the human body this automatic, involuntary process still goes on with very little trouble until it reaches a point in the body where man, the thinking animal, tries to control it by conscious thought. =a question of evacuation.= much of the misconception about constipation arises from the mistaken idea that this is a disorder of the whole intestine or at least of the whole colon. as a matter of fact, the trouble is almost wholly in the rectum. there is no trouble with the general traffic movement, but only with the unloading at the terminus. in my experience, the patient reports that he feels the fecal mass in the lower part of the rectum, but that he is unable to expel it. examination by finger or by x-ray reveals a mass in the rectal pouch. if there is a piling up of freight further back on the line, it is only because the unloading process has been delayed at the terminus. so long as the bowel-content is in the region of automatic control, there is very little likelihood of trouble. an occasional case of organic trouble--appendicitis, lead-colic, mechanical obstruction, new growths or spinal-cord disease--may cause a real blockade, but in ninety-nine cases out of every hundred there is little trouble so long as the involuntary muscles, working automatically under the direction of the subconscious mind, are in control. by slow or rapid stages, on time or behind time, the bowel-content reaches the upper part of the rectum and passes through a little valve into the lower pouch. here is where the trouble begins. =meddlesome interference.= in the natural state the little human, like the other animals, empties his bowel whenever the fecal mass enters the lower portion of the rectum. the presence of the mass in the rectum constitutes a call to stool which is responded to as unthinkingly as is the desire for air in the taking of a breath. but the tiny child soon has to learn to control some of his natural functions. at the lower end of the rectum there is a purse-string muscle called the _sphincter-ani_, an involuntary muscle which may with training be brought partly under voluntary control. under the demands of civilization, the baby learns to tighten up this muscle until the proper time for evacuation. then, if he be normal, he lets go, the muscles higher up contract and the bowel empties itself automatically, as it always did before civilization began. there is, however, a possibility of trouble whenever the conscious mind tries to assume control of functions which are meant to be automatic. under certain conditions necessary control becomes meddlesome interference. if the child for one reason or another takes too much interest in the function of elimination; if he likes too much the sense-gratification from stimulation of the rectal nerves and learns to increase this gratification by holding back the fecal mass; if he gets the idea that the function is "not nice" and takes the interest that one naturally feels in subjects that are taboo; or if he catches from his elders the suggestion that the bowel movement is a highly important process and that something disastrous is likely to happen unless it is successfully performed every day; then his very interest in the matter tends to interfere with automatic regulation, and to cause trouble. just as people often find it hard to let go the bladder muscle and urinate when in a hurry or under observation, and just as an apprehensive woman in childbirth tightens up the purse-string muscle of the womb, so the little child, or the grown up who catches the suggestion of difficulty in the bowel movement, loses the trick of letting go. instead of merely exercising control by temporarily inhibiting the function, he tries to carry through the process itself by voluntary control--and fails. constipation is a perfect example of the power of suggestion, and of the troublesome effect of a fear-idea in the realm of automatic functions. food and constipation since the waste matter from all foods finally reaches the rectum, and since constipation is merely a difficulty in the forces of expulsion, it is hard to see how any normal food in the quantities usually eaten could have the slightest effect on the problem. when we remember that it takes food from twelve to twenty-four hours to reach the rectum, and that it has during all that time been subjected to the action of the powerful chemicals of the digestive tract, it is hard to imagine a piece of cheese, of whatever variety, strong enough to stop the contraction of the muscles of the upper rectum or to tie the sphincter-muscle into a knot. it would be difficult to find a food which could pass without effect through twenty-seven feet of intestinal tubing only to become suddenly effective on the wall of the rectum. if the wrong kind of food is the cause of constipation, why does the rectum prove to be the most refractory portion of the tube? on what principle could a piece of chocolate inhibit the call to stool or contract the sphincter muscle? on the other hand, even if it should be conceded that constipation were the result of lack of lubricating secretions in the colon, how could two tablespoonfuls of mineral oil be a sufficient lubricant after being mixed with liquid and solid food through many feet of the intestinal tract? =an adaptable apparatus.= the lining of the intestines has plenty of secretions to take care of its function. it is as well adapted to the vicissitudes of life as are the other parts of the body. the muscular coat is no more liable to paralysis or spasm than are the voluntary muscles. as the skin adapts itself to all waters and all weathers, and as the lungs adjust themselves to varying air-pressures, so the intestinal wall makes ready adaptation to any common-sense demands, adjusting itself with ease to an athletic or a sedentary life, and to the normal variations of diet. what man has eaten throughout the centuries man may eat to-day. if you will but believe it, your intestines will make no more objection to white bread, blackberries, and cheese, along with all other ordinary articles of food, than the skin makes to varying kinds of water. naturally, the suggested idea that a food will constipate tends to carry itself out to fulfilment and to prevent the call to stool from rising to the level of consciousness; but the real force lies not in the food but in the suggestion. =the bran fad.= it is when we try to improve on the normal human diet that we really insult the body. he who leaves off eating nourishing white bread and takes to bran muffins is simply cheating his body. bran has a small food value, but the human body is not made to extract it. not only does bran fail to give us any nourishment itself, but it lessens the power of the intestines to care for other food.[55] the fad for bran is based on the well-known fact that we need a certain quantity of bulk in order to stimulate the intestinal wall to normal peristalsis. we do need bulk, but not more than we naturally get from a normal and varied diet including a reasonable amount of fruit and vegetables. [footnote 55: see an article entitled "bread and bran," _journal of american medical association_, july 5, 1919, p. 36.] it is true that the suggestion of the efficacy of bran, dates, spinach, or any other food is frequently quite sufficient to give relief, temporarily, just as massage, manipulation of the vertebrae, the surgeon's knife, or mineral oil may be enough to carry the conviction of power to a suggestible individual. but who wants to take his suggestions in such inconvenient forms as these? =change of water.= another popular superstition centers around drinking-waters. there are people who cannot move from one town to another, much less take an extensive trip, without a fit of constipation--or a box of pills. if they only knew it, there is no water on earth which could make a person constipated. a new water, full of unusual minerals, might hasten the bowel movement, but on what possible principle could it retard it? constipation has nothing to do with food or with water, but solicitous care about either can hardly fail to create the trouble which it tries to avoid. the cure =taking off the brakes.= since constipation is wholly due to the acceptance of a false suggestion, the only logical cure must be release from the power of that suggestion. "he is able as soon as he thinks he is able"; not that thought gives the power, but that the right thought releases the inhibition of the mistaken thought. as soon as the brakes are taken off, the internal machinery is quite able to make the wheels go round. the bowel will empty itself if we let it. the function of elimination is not a new trick learned with difficulty by the aged, but a trick as old and as elemental as life itself. like balancing on a bicycle, it may not be done by any voluntary muscular effort, but it just does itself when one learns how. once the sense of power comes, once the mind forgets to be doubtful or afraid, then the old automatic habit invariably reasserts itself. meddlesome interference may throw the mechanism out of gear, but fortunately it cannot strip the gears. constipation is an inhibition or restraint of function, but is never a loss of function. no one is too old, no one is too fixed in the bad habit to relearn the old trick. i have had a good many patients with chronic constipation, but i have never had one who failed to learn. real conviction speedily brings success, and in many cases success seems to outrun conviction. so efficient is nature if she has only half a chance! =some people who learned.= unless you are over ninety-two, do not despair. one old lady of that age, a sort of patient by proxy, was able to cure herself without even one consultation. her daughter had been a patient of mine and had been cured of the constipation with which she had been busy for many years. the mother, who believed her own bowel paralyzed, had been in the habit of lying on the bed and taking a copious enema every second day of her life. when, however, she heard of her daughter's cure, the bright old woman gave up her enemas and let her bowels do their own functioning. she stayed cured until her death at ninety-five. =a fifty-year habit.= another old lady was not quite so easily convinced. she ridiculed the idea that her son of fifty, who had been "constipated in his cradle" could be cured of his lifelong habit, but he was cured. as long as there is life and the light of reason, so long may nature's functions be reã«stablished. =the whole family.= nor is any one too young to learn. a tiny baby is easily taught. there came to me for two consultations a mother and her two babies, all three constipated. the four-year-old child, mentally deficient, had been fed on milk of magnesia from his infancy, and the four-months-old baby had been started on the same path. i explained to the mother the mechanism of elimination, told her to give up cathartics, and to set a regular time for herself and the baby, but was a little dubious about the mentally deficient four-year-old. however she soon reported that they had all three promptly acquired the new habit. four years later she told me that they had never had any more trouble. =a record history.= when miss h. first came to my house, she told a story that was almost incredible. she said that for many months she had been taking eight tablespoonfuls of mineral oil three times a day besides a cathartic at night, and an enema in the morning. no wonder she was a little dubious over such mild treatment as mine seemed to be! constipation was only one of this young woman's troubles. she could not sleep and was so fatigued that she believed herself at the end of her physical capital. when she first came to me she had tears in her eyes most of the time and used to confide to various people that she was sure she was a patient that i could not cure,--a very common belief among nervous invalids! she was sure that i did not understand her case, and that she could not get anything out of this kind of treatment. it was only a very short time, however, before her bowels were functioning like those of a normal person. she lost her insomnia and her fatigue and went away as well as ever. when she got back to her office, she found that her old position, which she had believed secure to her, had been given to another. she had to go out and hunt a new job and face conditions harder than she had had before, but she came through with flying colors. a short time ago miss h. came back to see me,--a happy, robust young woman, very different from the person i had first known. she assured me that she had never had any return of her old symptoms and that she was as well as a person could be. =living up to a suggestion.= mrs. t. had not had a natural movement of the bowels in twenty-five years. after the birth of a child, twenty-five years before, her physician had told her that her muscles had been so badly torn in labor that they could not carry through a natural movement. after that she had never gone a day without a pill or an enema. i explained to her that when any muscle of the rectum is injured in childbirth, it is the sphincter-ani, and that since this is the muscle whose contraction holds back the bowel content, its injury would tend to over-free evacuation rather than to constipation. she saw the point and within two or three days regained her old power of spontaneous evacuation. =practical steps.= the first step, then, in acquiring normal habits is the conviction of the integrity of our physical machines and a determination not to interfere by thought, or by physical meddling, with the elemental functions of our bodies. after this all-important step, there are a few practical suggestions which it is well to follow. most of them are nothing more than the common-sense habits of personal hygiene which are so obvious as to be almost axiomatic, but which are nevertheless often neglected: 1 eat three square meals a day. 2 drink when thirsty, having conveniently at hand the facilities for drinking. 3 heed the call to stool as you heed the call of hunger. when the stool passes the little valve between the upper and lower portions of the rectum, it gives the signal that the time for evacuation has come. if this signal is always heeded, it will automatically start the machinery that leads to evacuation. if it is persistently ignored because one is too busy, or because the mind is filled with the idea of disability, the call very soon fails to rise to the level of consciousness. the feces remain in the rectum, and the bad habit is begun. 4 choose a regular time and keep that appointment with yourself as regularly as possible. in all the activities of nature, there is a rhythm which it is well to observe. 5 take time to acquire the habit. do not be in a hurry. do not strain. no amount of effort will start the movement. just let it come of itself. 6 finally, should the unconscious suggestion of lack of power stubbornly remain in force, take a small enema on the third day. if the waste matter accumulates for three or more days, the bulk becomes so great that the circular muscles of the rectum are unable to handle it, just as the fingers cannot squeeze down to expel water from too large a mass of wet blankets. take only a small enema--never over a quart at a time--and expel the water immediately. one or two such measures will bring away the mass in the rectum. the material farther up still contains food elements and is not yet ready for expulsion. lessen the amount of water each time until no outside help is needed. once you get the right idea, all enemas will be superfluous. summary if you would have in a nutshell an epitome of the truth about constipation, indigestion, insomnia, and the other functional disturbances common to nervous folk, you can do, no better than to commit to memory and store away for future reference that choice limerick of the centipede, which so admirably sums up the whole matter of meddlesome interference: a centipede was happy quite until a frog in fun said, "pray, which leg comes after which?" this raised her mind to such a pitch, she lay distracted in the ditch, considering how to run. whoever tries to consider "which leg comes after which" in any line of physiological activity, is pretty sure to find himself in the ditch considering how to run. wherefore, remember the centipede! chapter xii _in which handicaps are dropped_ a woman's ills "the female of the species" if ever there was a man who wished himself a woman, he has hidden away the desire within the recesses of his own heart. but one does not have to wait long to hear a member of the female sex exclaim with evident emotion, "oh, dear, i wish i had been born a man!" it is probable that if these same women were given the chance to transform themselves overnight, they would hesitate long when it actually came to the point. the joys of being a woman are real joys. however, in too many cases these joys seem hardly to compensate for the discomforts of the feminine organism. it is the body that drags. painful menstrual periods, the dreaded "change of life," various "female troubles" with a number of pregnancies scattered along between, make some of the daughters of eve feel that they spend a good deal of their lives paying a penalty merely for being women. brought up to believe themselves heirs to a curse laid on the first woman, they accept their discomforts with resignation and try to make the best of a bad business. ="since the war."= nothing is quite the same since the war. among other things we have learned that many of our so-called handicaps were nothing but illusions,--base libels on the female body. under the stern necessity of war the women of the world discovered that they could stand up under jobs which have until now been considered quite beyond their powers. society girls, who were used to coddling themselves, found a new joy in hard and continuous work; middle-aged women, who were supposed to be at the time of life when little could be expected of them, quite forgot themselves in service. ambulance drivers, nurses, welfare workers, farmerettes, red-cross workers, street-car conductors and "bell-boys," revealed to themselves and to the world unsuspected powers of endurance in a woman's body. although some of the heavier occupations still seem to be "man's work," better fitted for a man's sturdier body, we know now that many of these disabilities were merely a matter of tradition and of faulty training. there still remains, however, a goodly number of women who are continuously or periodically below par because of some form of feminine disability. some of these women are suffering from real physical handicaps, but many of them need to be told that they are disabled not by reason of being women but by reason of being nervous women. ="nerves" again.= despite the organic disturbances which may beset the reproductive organs, and despite the havoc wrought by venereal diseases, it may be said with absolute assurance that the majority of feminine ills are the result neither of the natural frailty of the female body, nor even of man's infringement of the social law, but are the direct result of false suggestion and of false attitudes toward the facts of the reproductive life. the trouble is less a difficulty with the reproductive organs than a difficulty with the reproductive instinct. "something wrong" with the instinct is translated by the subconscious mind into "something wrong" with the related generative organs, and converted into a physical pain. that this relation has always been dimly felt is shown by the fact that the early greeks called nervous disorders _hysteria_, from the greek word for womb. it is only lately, however, that the blame has been put in the right place and the trouble traced to the _instinct_ rather than to the _organs_ of reproduction. =why women are nervous.= although women hold no monopoly, it must be conceded that they are particularly prone to "nerves." the reason is not hard to find. since the leading factor in a neurosis is a disturbance of the insistent instinct of reproduction, a disturbance usually based on repression, then any class of persons in whom the instinct is particularly repressed would, in the very nature of the case, be particularly liable to nervousness. no one who thoroughly knows human nature would attempt to deny that woman is as strongly endowed as man with the great urge toward the perpetuation of the race, or that she has had to repress the instinct more severely than has man. the man insists on knowing that the children he provides for are his own children. whatever the degree of his own fidelity, he must be sure that his wife is true to him. thus has grown up the insistence that, no matter what man does, woman, if she is to be counted respectable, shall control the urge of the instinct and live up to the requirements of continence set for her by society. unfortunately, however, there is more often blind repression than rational control. the measures taken to prevent a girl's becoming a tom-boy are measures of sex-repression quite as much as of sex-differentiation. over-reaction of sensitive little souls to lessons in modesty often causes distortion of normal sex-development. ignorance concerning the phenomena of life is commended as innocence, while it really implies a sex-curiosity which has been too severely repressed. the young woman blushes at thoughts of love, while the young man is filled with a sense of dignity. we smile at the picture of "miss philura's" confusion as she hesitatingly sends up to her creator a petition for the much-desired boon of a husband. but really, why shouldn't she want one? many a young woman, in order to deaden her senses to the unsuspected lure of the reproductive instinct by what is really an awkward attempt at _sublimation_, makes a fetish of dress and social position and considers only the marriage of convenience; or, on the other hand, she scorns men altogether and throws herself into a "career." young men are not so often taught to repress, but neither are they taught to swing their vital energies into altruistic channels through sublimation. since the woman of his class will not marry him until he has money, the young man too often satisfies his undirected instincts in a commercial way. the statistics of venereal diseases prove that here, as elsewhere, goods subject to barter are subject to contamination. in a late marriage, too often a contaminated body accompanies the material possessions which the standards of society have demanded of a husband. but the woman pays in still other coin for the repressions arising from faulty childhood training. unable to find expression for herself either in marriage or in devotion to work, because some old childish repression is still denying all outlet to her legitimate desire, she frequently falls into a neurosis; or if she escapes a real breakdown, she gives expression to unsatisfied longings in some isolated nervous symptoms which in many cases center about the organs of generation. there then results any one of the various functional disturbances which are only too often mistaken for organic disease. what is needed in cases like this is not a gynecologist nor a surgeon, but a psycho-pathologist--or perhaps only a grasp of the facts. let us look at the more common of these disturbances in order to gain an understanding of the situation. the menstrual period =potential motherhood.= among the normal phenomena of a woman's life is the recurring cycle of potential motherhood. every three or four weeks a new ovum or egg matures in the ovary and undergoes certain chemical changes, which send into the blood a substance called a hormone. this hormone is a messenger, stimulating the mucous membrane of the womb into making its velvet pile longer and softer, and its nutrient juices more abundant in readiness for the ovum. the same stimulus causes the whole organism to make ready for a new life. as in hunger, the chemistry of the body produces the muscle-tension that is felt as a craving for food, so this recurring chemical stimulus produces a definite craving in body and mind. this craving brings about an increased irritability or sensitiveness to stimuli which may result either in a joyous or a fretful mood. during sleep the social inhibitions are felt less distinctly and the sleeper dreams love-dreams woven from messages coming up from all the minute nerve-endings in the expectant reproductive organs. but if no germ-cell travels up the womb-canal and tube to meet and impregnate the ovum, the womb-lining rejects the egg as chemically unfit. all the furbishings are loosened from the walls and slowly cast out, constituting the menstrual flow. the phenomenon as a whole is a physiological function and should be accompanied by a sense of well-being and comfort as is the exercise of any other function, such as digestion or muscular activity. only too often, however, it is dreaded as an unmitigated disaster, a time for giving up work or fun and going to bed with a hot-water bottle until "the worst is over." let us see how this perversion comes about. =why menstruation is painful.= what sort of atmosphere is created for the young girl as she attains puberty? most girls get their first inkling of the menstrual period from the periodic "sick spells" of mother or sister. this knowledge comes without conscious thought and is a direct observation of the subconscious mind, which records impressions with the accuracy and completeness of a photographic plate. hearing the talk about a "sick-time" and observing the signs of "cramps" among older friends, the young girl's subconscious mind plays up to the suggestion and recoils with fear from the newly experienced sensations in the maturing organs of reproduction. this recoil of fear interferes with the circulation in the functioning organs, just as fear blanches the face or hinders digestion. there is several times as much blood in the stomach when it is full of food as there is between meals, but we do not for this reason fancy that we have a pain after each meal. there is more blood in the generative organs during their functioning, but this means pain only when fear ties up the circulation and causes undue congestion. fear acts further on the sturdy muscle of the womb, tying it up into just such knots as we feel in the esophagus when we say that we have a lump in the throat. it is safe to say that ninety-five cases of painful menstruation out of every hundred are caused by fear and by the expectation of pain. the cysts and tumors responsible for pain are so rare as to be fairly negligible, when compared with these other causes. dr. clelia duel mosher of stanford university has for many years carried on careful investigations among the students of the university. after describing in detail certain physical exercises which she has found of value, she continues: but more important even than this is an alteration of the morbid attitude of women themselves toward this function; and almost equally essential is a fundamental change in the habit of mind on our part as physicians; for do we not tend to translate too much, the whole of a woman's life into terms of menstruation? if every young girl were taught that menstruation is not normally a "bad time" and that pain or incapacity at that period is as discreditable and unnecessary as bad breath due to decaying teeth, we might almost look for a revolution in the physical life of women.... in my experience the traditional treatment of rest in bed, directing the attention solely to the sex-zone of the body, and the accepted theory that it is an inevitable illness while at the same time the mind is without occupation, produces a morbid attitude and favors the development and exaggeration of whatever symptoms there may be.[56] [footnote 56: clelia duel mosher: _health and the woman movement_, pp. 25, 26, 19.] =pre-menstrual discomfort.= if it be objected that women often feel badly for a day or two before the period begins, before they know that it is due, and that this feeling of discomfort could not be caused by fear and expectation, it is easy to reply that the subconscious mind knows perfectly what is happening within the body. the emotion of fear, working within the subconscious, is able to translate all the varying bodily sensations into feelings of distress without any knowledge on the part of the conscious mind. sometimes before the period begins, a girl feels blue and upset for a day or two, a sign that the instinct is getting discouraged. the whole body is saying, "get ready, get ready," but it has gotten ready many times before, and to no purpose. unsatisfied striving brings discouragement. what reaches consciousness is a feeling of pessimism and a general dissatisfaction with life as a whole. if, instead of giving in to the blues or going to bed and predicting a pain, the girl finds other outlets for her energy, she finds that after all, her instinct may be satisfied in indirect ways and that she has strangely come into a new supply of _vim_. =the purpose of the pain.= although suggestion is behind all nervous symptoms, there is a deeper reason for the disturbance. when an unhealthy suggestion is seized and acted upon, it is because some unsatisfied part of the personality sees in it a chance for accomplishing its own ends. the pre-menstrual period is the blooming-time, the mating-time, the springtime of the organism. that means eminently a time for coming into notice, that one's charms may attract the desired complement. but if the rightfully insistent instinctive desires are held in check by unnatural repressions and misapplied social restrictions, the starved instinct can obtain expression only by a concealment of purpose. the disguise assumed is often one of indifference or positive distaste for the allurements of the other sex. but, as we know, an instinctive desire will not be denied. in this case, the misguided instinct which has been given the suggestion that menstruation means illness, fits this conception into the scheme of things and obtains notice in a roundabout way by the attention given to the invalid. =the treatment.= to find that the symptom has a purpose rather than a cause gives the indication for the treatment. judicious neglect causes the symptom to cease by defeating its very purpose,--that of drawing attention to itself. the person who never mentions her discomfort, thinks about it as little as possible, and goes about her business as usual, is likely to find her trouble gone before she realizes it.[57] [footnote 57: violent exercise at this time is unwise, but continuing one's usual activity helps the circulation and keeps the mind from centering on the affected part. the physiological congestion is unduly intensified by standing; therefore all employments should afford facilities for the woman to sit at least part of the time while continuing work.] a little explanation gives the patient insight into the workings of her own mind, and usually causes the pain to disappear in short order. astonished, indeed, and filled with gratitude have been some of my young-women patients who had all their lives been unable to plan any work or social engagements for the time of this functioning. many of them were the worst kind of doubters when they were told that to go to bed and center their attention on the generative organs only made the muscles tighten up and the circulation congest. they could not conceive themselves up and around, pursuing their normal life during such a time. however, as they have found by experience that this point of view is not an optimistic dream, they have broken up the confidence-game which their subconscious had been playing on them, and have gone on their way rejoicing. there was one young girl, a doctor's daughter, who suffered continuously from pain in the abdomen, and from back-pain which increased so greatly at the time of the menses that she was in the habit of going to bed for several days, to be waited on with solicitous care by her family. in an attempt to cure the trouble she had undergone an operation to suspend the uterus, but the pain had continued as before. when she came to me, i explained to her that there was no physical difficulty and that her trouble was wholly nervous. i made her play tennis every day and she had just finished a game when her period came on. she stayed up for luncheon, went for a walk in the afternoon, ate her dinner with the family, and behaved like other people. her mother telephoned that evening and when i told her what her daughter had been doing, she gasped in astonishment. she had difficulty in believing that the new order was not miracle but simply the working out of natural law. since that time her daughter has had no more trouble. =the ounce of prevention.= if young girls had wiser counselors in their mothers and physicians, the misconception would never occur, and such an indirect outlet would not be needed; the organic sensations incident to puberty and the recurring menstrual period would have something of the significance of the annunciation to mary, bringing wonder and a sense of well-being. when your little daughter arrives at maturity, give her a joyous initiation into the noble order of women. she will welcome the new function as a badge of womanhood and as a harbinger of wonderful things to come. a girl of fifteen came under my care to be helped out of a mood of increasing depression and uneasiness. her glance was furtive, yet anxiously expectant. tears came unbidden as she sat alone or fingered the keys of the piano. tactful questioning elicited no response as to reasons for her unhappiness. opportunities for giving confidence were not accepted. at a chance moment our talk drifted to the subject of menstruation. "your periods are regular and easy; and do you know what they are for?" then i painted for her a picture of the preparations that are made throughout the whole organism, for the germ-cell that comes each month and has in it all the possibilities of a new little life. the result of this confidential talk may seem fanciful to any one but an eye-witness. we had only a week's association, but the depression ceased, the furtive look and deprecatory manner were replaced by a joyous buoyancy. in a few weeks the thin neck and awkward body rounded out into the symmetry which usually precedes the establishment of puberty, but which was delayed in this case until the unconscious conflict resolved itself. =in the large.= looked at from any angle, this subject is an important one. there are involved not only the physical comfort and convenience of the sufferers themselves, but also the economic prospects of women as a whole. if women are to demand equal opportunity and equal pay, they must be able to do equal work without periodic times of illness. when employers of women tell us that they regularly have to hire extra help because some of their workers lose time each month, we realize how great is the aggregate of economic waste, a waste which would assuredly be justified if the health of the country's womanhood were really involved, but which is inefficient and unnecessary when caused merely by ignorant tradition. "up to standard every day of every week," is a slogan quite within the range of possibility for all but the seriously ill. when reduced to their lowest terms, the inconveniences of this function are not great and are not too dear a price to pay for the possibilities of motherhood. the "change of life" =another phantom peril.= as the young girl is taught to fear the menstrual period, so the older woman is taught to dread the time when the periods shall cease. despite the general enlightenment of this day and age, the menopause or "change of life" is all too frequently feared as a "critical period" in a woman's life, a time of distressing physical sensations and even of danger to mental balance. as a matter of fact, the menopause is a physiological process which should be accomplished with as little mental and physical disturbance as accompanies the establishment of puberty. the same internal secretion is concerned in both. when the function of ovulation ceases the body has to find a new way to dispose of the internal secretion of the ovary. its presence in the blood is the cause of the sudden dilatation of the blood-vessels that is known as the "hot flash." the matter is altogether a problem of chemistry, with the necessity for a new adjustment among the glands of internal secretion. the body easily manages this if left to itself, but is greatly interfered with by the wrong suggestion and emotion. we have already seen how quickly emotion affects all secretions and how easily the adrenal and thyroid glands are influenced by fear. this is the root of the trouble in many cases of difficult "change." if an occasional body is not quite able to regulate the chemical readjustment, we may have to administer the glands of some other animal, but in the majority of cases, the body, unhampered by an extra burden of fear, is quite able to make its own adjustments. the hot flash passes in a moment, if not prolonged by emotion or if not converted into a habit by attention. one source of trouble in the menopause is that it comes at a time in a woman's life when she is likely to have too much leisure. in no way can a woman so easily handicap her body at this time as by stopping work and being afraid. those women who have to go on as usual find themselves past the change almost before they know it,--unless they consider themselves abused, and worry over the necessity for working through such a "critical time." =three rules.= here are a few pointers which have have been of help to a number of women: 1 remember that this is a physiological process and therefore abundantly safeguarded by nature. if you don't expect trouble you will not be likely to find it. 2 remember that the sweating and flushing are made worse by notice. 3 do everything in your power to keep from the public the knowledge that you are no longer a potential mother. if you are past forty, do not mop your face or gasp for breath or carry a fan to the theater! shun attention and fear, and you will be surprised at the ease with which the "change" is effected. =nature's last chance.= while we are on the subject of the middle-aged woman, it may be well to mention a phenomenon sometimes noticed in the early forties. often an "old maid" who has considered herself settled for life in her bachelor estate, suddenly takes to herself a husband. (i use the verb advisedly!) mothers who have thought their child-bearing days long past sometimes find themselves pregnant. "the child of her old age" is not an uncommon occurrence. unmarried women who have "kept straight" all their lives sometimes go down before temptation at this late time. there is a reason. it is as though nature were making a last desperate attempt to produce another life before it is too late, speeding up all the internal secretions and flashing insistent messages throughout the whole organism. it may help some woman who feels herself inexplicably impelled toward the male sex to know that she is not being "tempted by the devil" but merely driven by the insistent chemicals within her body. she is likely to rationalize and tell herself that it is too bad for a worth-while person like herself to leave no progeny behind her; or she may say, as one of my patients did when contemplating running away with another woman's husband,--that she could make that man so much happier than his wife did, and that she really owed it to him as well as to herself. when a woman knows what is the matter with her, it makes it easier to bide her time and wait for the demands of nature to subside. chemicals may not be so romantic as love, but neither are they so melodramatic! other troubles ="speaking of operations."= physicians are often called upon to diagnose some such vague symptom as pain in the abdomen, back and head; ache in the legs; constipation, or loss of appetite. since the patient is very insistent that something shall be done, the physician may be driven to operate, even when he has an uneasy feeling that the trouble is "merely nervous." sixty per cent. of the operations on women are necessitated by the results of gonorrheal infection. next in frequency up to recent date, have been operations for nervous symptoms which could in no way be reached by the knife. only too often a nerve-specialist hears the tale of an operation which was supposed to cure a certain pain but which left it worse rather than better. it is a pleasure to see some of these pains disappear under a little re-education, but one cannot help wishing that the re-education had come before the knife instead of after it. a skilled surgeon can cut almost anything out of a person's body, but he cannot cut out an instinct. it sometimes takes great skill to determine whether the trouble is an organic affection or a functional disturbance caused by the misdirected instinct of reproduction. often, however, the clinical pictures are so different as to leave no room for doubt, provided the diagnostician has his eyes open and is not over-persuaded by the importunity of the poor neurotic, who insists that the surgeon shall remove her appendix, her gall-bladder, her genital organs, and her tonsils, and who finally comes back that he may have a whack at the operation scar. =the bearing of children.= a number of years ago i became acquainted with a charming young married woman who had all her life recoiled with fear from the phenomena of sex. she had been afraid of menstruation and of marriage, and had at this time almost a phobia for pregnancy and childbirth. before long she came to me in terror, telling me that she had become pregnant. i explained to her that pregnancy is the time when most women are at their best, that the nausea which is often troublesome in the beginning is caused merely by a mixing of messages from the autonomic nerves, which refer new sensations in the womb to the more usual center of activity in the stomach; and that after the body has become accustomed to these sensations, most women experience a greater sense of well-being and peace than at any other time in life. we had a conversation or two on the subject and everything seemed to go well for a while. as it happened, this young woman and her husband came to call on me one afternoon just before the baby was expected. during the visit she began to show signs of being in labor. again she was in terror. again i explained the phenomena of labor, telling her that the womb-contractions are caused by the presence in the blood of a chemical secretion (hormone) which continues its good work as long as there is a state of confidence, but which sometimes stops under fear or apprehension. i explained that these womb-efforts are a peristaltic movement, a contraction of the upper muscles and a letting go of the purse-string muscle at the mouth of the womb, and that fear only tends to tie up this purse-string muscle, making a difficult process out of one which was intended by nature to be much more simple. she seemed to understand and to lose a good deal of her fright. about six o'clock the couple went home on the street car from the upper end of pasadena to the far end of los angeles. the next morning i had a jubilant telephone message from the happy father, announcing that the boy-baby had arrived at midnight and that, wonderful to relate, he had come without the mother's experiencing any pain whatever. i give this account for what it is worth, without of course contending that labor could always be as easy as this. it happened that this girl was a normal, healthy woman and that there were no complications of any kind in the process of childbirth. a right attitude of mind could not have corrected any physical difficulty, but it did seem to help her let go of her fear, which would of itself have caused long and painful labor. a patient once told me that when her first baby came, she happened to be out in the country where she had to call in a doctor whom she did not know. he was an uncouth sort of fellow who inspired fear rather than confidence. she soon found that labor stopped whenever he came into the room, and started again when he went out. she had the good sense to send him out and complete her labor with only the help of her mother. unfortunate is the obstetrician who does not know how to inspire a feeling of confidence in his patients. even childbirth may be mightily helped or hindered by the mother's state of mind. summary a woman's body has more stability than she knows. it is sometimes out of order, but it is more often misunderstood; usually it is an unobtrusive and satisfactory instrument, quite fit for its daily tasks. the average woman is really well put together. we hear about the ones who have difficulty, but not about the great majority who do not. we notice the few who are upset during the menopause, and forget all the others. to be comfortable and efficient most of the time is, after all, merely to be "like folks." the special functions which nature has been perfecting in a woman's body are as a rule, easily carried through unless complicated by false ideas or by fear. if the woman who has no organic difficulty but who still finds herself handicapped by her body, will cease being either resigned to her languishing lot or envious of her stalwart brothers; if instead she will set out to learn how to be efficient as a woman, she will find that many of her ills are not the blunders of an inefficient creator, but are home-made products, which quickly vanish in the light of understanding. chapter xiii _in which we lose our dread of night._ that interesting insomnia the fear of staying awake to sleep or not to sleep! that is the question. in all the world there is nothing to equal it in importance,--to the man with insomnia. his days are mere interludes between troubled nights spent in restless tossing to and fro and feverish worry over the weary day to come. his mind filled with ideas about the disastrous effects of insomnia, he imagines himself fast sliding down hill toward the grave or the insane-asylum. it is true that his conversation very often politely begins something like this: "good morning. did you sleep well last night?" but if we fail to respond by an equally polite "and i hope you had a good night?" he seems restless until he has somehow disillusioned us by stating the exact number of hours and minutes during which he was able to lose himself in slumber. we must not ridicule the man who doesn't sleep. we are all very much alike. if any one of us happens to lie awake for a night or two, he is likely to get into a panic, and if the spell should last a week, he begins looking up steamship agents and talking of voyages to southern seas. the fact is that most people are dreadfully afraid of insomnia. knowing the effects of a few nights of enforced wakefulness, and having had a little experience with the fagged feeling after a restless night, they believe themselves only logical when they fall into a panic over the prospect of persistent insomnia. =two kinds of wakefulness.= as a matter of fact, insomnia is a phantom peril. there is not the slightest danger from lying awake nights, provided one is not kept awake by some irritating physical stimulus. all fear of insomnia is based on ignorance of the difference between enforced wakefulness and deliberate wakefulness, or insomnia. the man who has acquired the habit may stay awake almost indefinitely without appreciable harm, but the one who is kept awake for a week by a pain, by a chemical poison from infection, or by the necessity for staying up on his job, may easily be in a state of exhaustion. even in cases of prolonged pain or over-exertion, the body tends to maintain its equilibrium by hastening its rate of repair and by falling asleep before the danger point is reached. it is almost impossible to impair permanently the tissue of the brain except in the presence of a chemical irritant. in case of infection we often have to give medicine to neutralize the effect of the poison or to resort to narcotics which make the brain cells less susceptible to irritation. but nervous insomnia is another story. a harmless habit =long-lived insomniacs.= a man of my acquaintance once said in all seriousness and with evident alarm: "i am following in the footsteps of my mother. she lived to be seventy years old and she had insomnia all her life." if this man had been preaching a sermon on the harmlessness of chronic insomnia, he could not have chosen a better text, but he seemed just as much concerned about himself as if his mother had died from the effects of three months' wakefulness. people can live healthy lives during twenty or thirty years of insomnia because chronic insomnia is nothing more or less than a habit, and "habit spells ease." the brain cells are not irritated by either internal or external stimuli; there is no effort to keep awake; virtually no energy is expended,--except in restless tossing and worry. if the body is kept still and emotion eliminated, fatigue products are washed away and the reserves are filled in with perfect ease. =thinking in circles.= habit means automatic, subconscious activity, with the least expenditure of energy and the least amount of fatigue. we have already noted the ease with which heart and diaphragm muscles carry on their work from the beginning of life to its end. anything relegated to the subconscious mind can be kept up almost indefinitely without tire, and to this subconscious type of activity belong the thoughts of a chronic insomniac. despite all assertions to the contrary, his conscious mind is not really awake. if he is questioned about the happenings of the night, he is likely to have been unaware of the most audible noises. the thoughts that run through his brain are not new, constructive, energy-consuming thoughts, but the same old thoughts that have been going around in circles for days and weeks at a time. it is true that a person sometimes chooses to wake up and do his constructive planning in the night. this kind of thought does bring fatigue, up to a certain point. after that the body hastens its rate of repair or automatically goes to sleep. activity of this kind is always a matter of choice. he who really prefers sleep will shut the drawers containing the day's business and leave them shut until morning. =day-dreaming at night.= however, the man who makes a practice of staying awake rarely does much real thinking. he lets the thoughts run through his mind as they will, builds air-castles of things he would like to do and can't, or other kinds of air-castles about the disastrous effects of his insomnia on the day that is to come; he worries over his health, or his finances, and grieves over his sorrows. he is really indulging himself, thinking the thoughts he likes most to think, and these consume but little energy. like a horse that knows the rounds, they can go jogging on indefinitely without guidance from the driver. what causes the fatigue =tossing and fretting.= the thing that tires is not the insomnia but the emotion over the insomnia. if people who fail to sleep are perpetually fagged out, it is not from loss of sleep, but from worry and tossing. often they spend a good deal of the night feeling sorry for themselves. they turn and toss, exclaiming with each turn: "why don't i sleep? how badly i shall feel to-morrow! what a night! what a night!" such a spree of emotionalism can hardly fail to tire, but it is not fair to blame the insomnia. he who makes up his mind to it can rest almost as well without sleep as with it, provided he keeps his mind calm and his body relaxed. "decent hygienic conditions" demand not necessarily eight hours of sleep but eight hours of quiet rest in bed. tossing about drives away sleep and uses up energy. i make it a rule that my patients shall not turn over more than four times during the night. this is more important than that they should sleep. to be sure, i do not stay awake to enforce the rule, but most people catch the idea very quickly and before they know it they are sleeping. how to go to sleep =ceasing to care.= the best way to learn to sleep is not to care whether you do or not. nothing could be better than dubois's advice: "don't look for sleep; it flies away like a pigeon when one pursues it."[58] attention to anything keeps the mind awake, and most of all, attention to sleep. more than one person has waked up to see whether or not he was going to sleep. we cannot, however, fool ourselves by merely pretending indifference. the only sensible way is to get the facts firmly fixed in our minds so that we actually realize that we do not need more sleep than our bodies take. as soon as it is realized that insomnia is really of no importance, it tends to disappear. [footnote 58: dubois: _psychic treatment of nervous disorders_, p. 339.] =catching the idea.= there came one day for consultation a very healthy-looking woman, a deaconess of the lutheran church. "doctor," she said, "i came to get relief from insomnia. for twenty years i have not slept more than one or two hours a night." "why do you want more?" i asked. "why, isn't it very unhealthy not to sleep?" she exclaimed in astonishment. "evidently not," i answered. this woman had tried every doctor she could think of, including the splendid s. weir mitchell. her insomnia had become a preoccupation with her, her chief thought in life. all i did was to explain to her that her body had been getting all the sleep it needed, and that neither body nor mind was in the least run down after twenty years of sleeplessness. "when you cease being interested in your insomnia, it will go away, although from a health standpoint it matters very little whether it does or not." we had two conversations on the subject, and a week later she came back to tell me that she was sleeping eight hours a night. one woman had had insomnia for thirty years. after i had explained to her that her body had adjusted itself to this way of living and that she need not try to get more sleep, she snored so loud all night and every night that the rest of the family began to complain! a certain banker proved very quick at catching the idea. he had been so troubled with insomnia and intense weakness that his doctors prescribed a six-months voyage in southern waters. knowing that my prescriptions involved a change in point of view rather than in scene, he came to me. although he had been getting only about half an hour's sleep a night, he went to sleep in his chair the first evening, and then went upstairs and slept all night. he resumed his duties at the bank, walking a mile and a half the first day and three miles the second. during the months following, he reported, "no more insomnia." =keeping account.= a bright young college graduate came to me for a number of ailments, chief among them being sleeplessness. she was also overcome by fatigue, having spent four months in bed. a four-mile walk in the caã±on and a few other such outings soon dispelled the fatigue, but the insomnia proved more obstinate. after she had been with me for a week or two, i took her aside one day for a little talk. "well?" i said as we sat down. then she began: "sunday night i was awake from half-past one to four, monday from twelve to one, tuesday from one to three, wednesday from two to four, thursday--" by this time she became aware of the quizzical expression on my face and began to be embarrassed. then she stopped and laughed. "well," she said, "i did not know that i was paying so much attention to my sleep." she was bright enough to see the point at once, gave up her preoccupation in the all-absorbing topic and promptly forgot to have any trouble with so natural a function as sleep. =making new associations.= examples like this show how natural is childlike slumber when once we take away the inhibitions of a hampering idea. age-old habits like sleep are not lost, but they may easily be interfered with by a little too much attention. when a person who can scarcely keep his eyes open all the evening is instantly wide awake as soon as his head touches the pillow, we may be sure that a part of his trouble comes from the wrong associations which he has built up with the thought of night. when a dear little old lady told me of her constant state of apprehension about going to bed, i said to her: "when i go to my room, the darkness says sleep. when i take off my clothes, the very act says sleep. when i put my head on the pillow, the pillow says sleep." she liked that and found herself able to sleep all night. the next evening she wanted another "sleeping-potion" but as i did not want her to become dependent on anybody's suggestion, i put my mouth up close to her ear and whispered, "abra ca dabra, dum, dum, dum." she laughed, but saw the point. after that she slept very well. she merely broke the habit by making a new kind of association with the thought of bed. nature did the rest. it seems hardly necessary to remark that drug-taking is the most inefficient way of handling the situation. everybody knows that narcotics are harmful to the delicate cells of the brain and that the dose has to be continuously increased in cases of chronic insomnia. if a person realizes that the drug is far more harmful than the insomnia itself, he is weak indeed to yield to temptation for the sake of a few nights of sleep. as the cause of insomnia is psychic, so the only logical cure is a new idea and a new attitude of mind. the purpose of insomnia like all nervous symptoms, insomnia is not an affliction but an indulgence. somehow, and in ways unknown to the conscious mind, it brings a certain amount of satisfaction to a part of the personality. no matter how unpleasant it may be, no matter how much we consciously fear it, something inside chooses to stay awake. started, as a rule, through suggestion or imitation, insomnia is sometimes kept up as a means of making ourselves seem important,--to ourselves and to others. it at least provides an excuse for thinking and talking about ourselves, and furnishes a certain feeling of distinction. if something within us craves attention, even staying awake may not be too dear a price to pay for that attention. strange to say, there are other times when the insomnia is chosen by the primitive subconscious mind with the idea of doing penance for supposed sins whose evil effects might possibly be avoided by this kind of expiation. analysis shows that motives like this are not so uncommon as might be supposed. in other cases insomnia is chosen for the chance it gives for phantasy-building. a person denied the right kind of outlet for his instincts may so enjoy the day-dreaming habit that he prolongs it into the night, really preferring it to sleep. such a state of affairs is not at all incompatible with an intense conscious desire to sleep and a real fear of insomnia. so strange may be the motives hidden away within the depths of the most prosaic individual! summary nervous insomnia is something which a part of us makes use of and another part fears. it is a mistake on both sides. although not in the least dangerous, the habit can hardly be considered a satisfactory form of amusement. nature has provided a better way to spend the night, a way to which she speedily brings us when we choose to let her do it. we do not have to ask for sleep as for a special boon which may be denied. we simply have to lie down in trust, expecting to be carried away like a child. if our expectation is not at once realized we can still trust, as with relaxed mind and body we lie in calm content, knowing that nature is, minute by minute, restoring us for another day. chapter xiv _in which we raise our thresholds_ feeling our feelings finely strung violins the young girl had been telling me about her symptoms. "you know, doctor," she said. "i am a very sensitive person. in fact, i have always been told that i am like a finely strung violin." there was pride in every tone of her voice,--pride and satisfaction over possessing an organization so superior to the common clay of the average person. it was a typical remark, and showed clearly that this girl belonged among the nervous folk. for the nervous person is not only over-sensitive, but he accepts his condition with a secret and half-conscious pride as a token of superiority. it seems that there are a good many kinds of sensitiveness. whether it is a good or bad possession depends entirely on what kind of things a person is sensitive to. if he is quick to take in a situation, easily impressed with the needs of others, open-doored to beauty and to the appeal of the spiritual, keenly alive to the humorous, even when the joke is on himself and the situation uncomfortable, then surely he has a right to be glad of his sensitiveness. but too often the word means something else. it means feeling, intensely, physical sensations of which most people are unaware, or reacting emotionally to situations which call for no such response. it means, in short, feeling our feelings and liking to feel them. there seems to be nothing particularly praiseworthy or desirable about this kind of sensitiveness. if this is what it means to be a "finely-wrought violin," it might even be better to be a bass drum which can stand a few poundings without ruin to its constitution. "but," says the sensitive person, "are we not born either violins or drums? is not heredity rather than choice to blame? and what can a person do about it?" these questions are so closely bound up with the problems of nervous symptoms of indigestion, fatigue, a woman's ills, hysterical pains and sensations, and with all the problems of emotional control, that we shall do well to look more carefully into this question of sensibility, which is really the question of the relation of the individual to his environment. selecting our sensations =reaction and over-reaction.= every organism, if it is to live, must be normally sensitive to its environment. it must possess the power of response to stimuli. as the sea-anemone curls up at touch, and as the tiny baby blinks at the light, so must every living thing be able to sense and to react to the presence of a dangerous or a friendly force. only by a certain degree of irritability can it survive in the struggle for existence. the five senses are simply different phases of the apparatus for receiving communications from the outside world. other parts of the machinery catch the manifold messages continually pouring into the brain from within our bodies themselves. these communications cannot be stopped nor can we prevent their impress on the cells of the brain and spinal cord, but we do have a good deal to say as to which ones shall be brought into the focus of attention and receive enough notice to become real, conscious sensations. =paying attention.= if a human being had to give conscious attention to every stimulus from the outer world and from his own body, to every signal which flashes itself along his sensory nerves to his brain, he would need a different kind of mind from his present efficient but limited apparatus. as it is, there is an admirable provision for taking care of the messages without overburdening consciousness. the stream of messages never stops, not even in sleep. but the conscious mind has its private secretary, the subconscious, to receive the messages and to answer them. during any five minutes of a walk down a city street a man has hundreds of visual images flashed upon the retina of the eye. his eye sees every little line in the faces of the passers-by, every detail of their clothing, the decorations on the buildings, the street signs overhead, the articles in the shop-windows, the paving of the sidewalks, the curbings and tracks which he crosses, and scores of other objects to most of which the man himself is oblivious. his ear hears every sound within hearing distance,--the honk of every horn, the clang of every bell, the voices of the people and the shuffle of feet. some part of his mind feels the press of his foot on the pavement, the rubbing of his heel on his stocking, the touch of his clothing all over his body, and all those so-called kinesthetic sensations,--sensations of motion and balance which keep him in equilibrium and on the move, to say nothing of the never-ending stream of messages from every cell of every muscle and tissue of his body. out of this constant rush of stimuli our man gives attention to only the smallest fraction. whatever is interesting to him, that he sees and hears and feels. all other sensations he passes by as indifferent. unless they come with extraordinary intensity, they do not get over into his consciousness at all. ="listening-in" on the subconscious.= the subconscious mind knows and needs to know what is happening in the farthermost cell of the body. it needs to know at any moment where the knees are, and the feet; otherwise the individual would fall in a heap whenever he forgot to watch his step. it needs to know just how much light is entering the eye, and how much blood is in the stomach. to this end it has a system of communication from every point in the body and this system is in constant operation. its messages never cease. but these messages were never meant to be in the focus of attention. they are meant only for the subconscious mind and are generally so low-toned as to be easily ignored unless one falls into the habit of listening for them. unless they are invested with a significance which does not belong to them, they will not emerge into consciousness as real sensations. =psychic thresholds.= boris sidis has given us a word which has proved very useful in this connection. the limit of sensitivity of a cell--the degree of irritability--he calls the stimulus-threshold.[59] as the wind must come in gusts to drive the rain in over a high doorsill, so must any stimulus--an idea or a sensation--come with sufficient force to get over the obstructions at the doorway of consciousness. these psychic thresholds do not maintain a constant level. they are raised or lowered at will by a hidden and automatic machinery, which is dependent entirely on the ideas already in consciousness, by the interest bestowed upon the newcomer. the intensity of the stimuli cannot be controlled, but the interest we feel in them and the welcome given them are very largely a matter of choice. [footnote 59: sidis: _foundations of normal and abnormal psychology_, chap. xxx.] each organism has a wide field of choice as to which ideas and which physical stimuli it shall welcome and which it shall shut out. we may raise our thresholds, build up a bulwark of indifference to a whole class of excitations, shut our mental doors, and pull down the shades; or we may lower the thresholds so that the slightest flicker of an idea or the smallest pin-prick of a sensation finds ready access to the center of attention. =thresholds and character.= there are certain thresholds made to shift frequently and easily. when one is hungry any food tastes good, for the threshold is low; but the food must be most tempting to be acceptable just after a hearty meal. on the other hand, a fairly constant threshold is maintained for many different kinds of stimuli. these stimuli are always bound together in groups, and make appeal depending upon the predominating interest. as anything pertaining to agriculture is noticed by a farmer, or any article of dress by a fashionable woman, so any stimulus coming from a "warm" group is welcomed, while any from a "cold" group is met by a high threshold. the kind of person one is depends on what kind of things are "warm" to him and what kind are "cold." the superman is one who has gained such conscious control of his psychic thresholds that he can raise and lower them at will in the interests of the social good. =thresholds and sensations.= the importance of these principles is obvious. the next chapter will show more of their influence on ideas and emotions; but for the present we will consider their lessons in the sphere of the physical. psychology speaks here in no uncertain terms to physiology. whoever becomes fascinated by the processes of his own body is bound to magnify the sensations from those processes, until the most insignificant message from the subconscious becomes a distressing and alarming symptom. the person whose mental ear is strained to catch every little creaking of his internal machinery can always hear some kind of rumble. if he deliberately lowers his thresholds to the whole class of stimuli pertaining to himself, there is small wonder that they sweep over the boundaries into consciousness with irresistible force. =the motives for sensitiveness.= sensitiveness is largely a matter of choice, but what determines choice? why is it that one person chooses altruism as the master threshold that determines the level of all the others, while another person who ought to be equally fine lowers his thresholds only to himself? what makes a person too interested in his own sensations and feelings? as usual there is a cause. the real cause back of most cases of chronic sensitiveness is an abnormal desire for attention. sometimes this love of attention arises from an under-developed instinct of self-assertion, or "inferiority complex." if there is a sense of inadequacy, a feeling of not being so important as other people, a person is quite likely to over-compensate by making himself seem important to himself and to others in the only way he knows. all unconsciously he develops an extreme sensitiveness which somehow heightens his self-regard by making him believe himself finely and delicately organized, and by securing the notice of his associates. or, again, the love of attention may be simply a sign of arrested development, a fixation of the narcissistic period of childhood which loves to look at itself and make the world look. or there may be lack of satisfaction of the normal adult love-life, a lack of the love and attention which the love-instinct naturally craves. if this instinct is not getting normal outlet, either directly through personal relationships or indirectly through a sublimated activity, what is more natural than that it should turn in on itself, dissociate its interest in other things and occupy itself with its own feelings, and at the same time secure the coveted attention through physical disability, with its necessity for special ministration? in any case there is likely to develop a general overreaction to all outside stimulation, a hypersensitiveness to some particular kind of stimulus, or a chronic hysterical pain which somehow serves the personality in ways unknown to itself. no one "feels his feelings" unless, despite all discomfort, he really enjoys them. a hard statement to accept perhaps, but one that is repeatedly proved by a specialist in "nerves"! determining causes =accidental association.= in many cases, the form which the sensitiveness takes is merely a matter of accident. often it is based on some small physical disability, as when a slight tendency to take cold is magnified into an intense fear of fresh air. sometimes a past fleeting pain which has become associated with the stream of thought of an emotional moment--what boris sidis calls the moment-consciousness--is perpetuated in consciousness in place of the repressed emotion. "in the determination of the pathology of hysteria, the accidental moment plays a much greater part than is generally recognized; if a painful affect--emotion--originates while eating but is repressed, it may produce nausea and vomiting and continue for months as an hysterical symptom."[60] [footnote 60: freud: _selected papers_, p. 2.] one of freud's patients, miss rosalie h----, found while taking singing-lessons that she often choked over notes of the middle register, although she took with ease notes higher and lower in the scale. it was revealed that this girl, who had a most unhappy home life, had, during a former period, often experienced this choking sensation from a painful emotion just before she went for her music lesson. some of the left-over sensations had remained during the singing, and as the middle notes happen to involve the same muscles as does a lump in one's throat, she had often found herself choking over these notes. later on, while living in a different city and in a wholly different environment, the physical sensations from her throat muscles, as they took these middle notes, brought back the associated sensations of choking,--without, however, uncovering the buried emotion.[61] many a painful hysterical affliction is based on just such mechanisms as these. as freud remarks, "the hysteric suffers mostly from reminiscences."[62] [footnote 61: ibid, p. 43.] [footnote 62: ibid, p. 5.] =subconscious symbolism.= sometimes, as we have seen, the form which a hypersensitiveness assumes is not determined by any physical sensation, either past or symbolism which acts out in the body the drama of the soul. =facing the facts.= whatever the motives and whatever the determining causes, hypersensibility is in any case a feeling of feelings which is not warranted by the present situation. hypersensitiveness is never anything but a makeshift kind of satisfaction. despite certain subconscious reasoning, it does not make one more important nor more beloved. neither does it furnish a real expression for that great creative love-instinct whose outlet, if it is to bring satisfaction, must be a real outlet into the external world. an understanding of the motives is helpful only when it makes clear that they are short-sighted motives and that the real desires back of them may be satisfied in better ways. some lowered thresholds as the public appetite for specific cases appears to be insatiable, we will give from real life some examples of low thresholds which were raised through re-education. one hesitates to write down these examples because when they are on paper they sound like advertisements of patent medicines. however, there is no magic in any of these cures, but only the working out of definite laws which may be used by other sufferers, if they only know. re-education through a knowledge of oneself and the laws at work really does remarkable things when it has a chance. ="danger-signals" without the danger.= there was the man who had queer feelings all over his body, especially in his head and stomach, and who considered these sensations as danger-signals warning him to stop. this man had worked up from messenger boy to a position next to the president in one of the transcontinental railroad systems. on the appearance of these "danger-signals" he had tried to resign but had been given a year's leave of absence instead. half the year had gone in rest-cure, but he was still afraid to eat or work, and believed himself "done for." after three weeks of re-education he saw that instead of having overdrawn his capital, he had in another sense overdrawn his sensations. he went away as fit as ever, finished his leave of absence doing hard labor on his farm, and then went back to even harder tasks, working for the government in the administration of the railroads during the war. he is still at work. =enjoying poor health.= there was the woman who had been an invalid for twenty years, doing little else during all that time than to feel her own feelings. because of the distressing sensations in her stomach, she had for a year taken nothing but liquid nourishment. she had queer feelings in her solar-plexus and indeed a general luxury of over-feeling. she could not leave her room nor have any visitors. she was the star invalid of the family, waited on by her two hard-working sisters who earned the living for them all. her sisters had inveigled her to my house under false pretenses, calling it a boarding-house and omitting to mention that i was a doctor, because "she guessed she knew more about her case than any doctor." for the first week i got in only one sentence a day,--just before i slipped out of the door after taking in her "liquid nourishment." but at the end of the week i announced that thereafter her meals would be served in the dining-room. when she found that there was to be no more liquid nourishment, she had to appear at the family table. after that it was only a short time before she was at home, cooking for her sisters. when she saw the role she had been unconsciously playing, she could hardly wish to go on with it. =feeling his legs.= mr. r. suffered from such severe and distressing pains in his legs that he believed himself on the verge of paralysis. he was also bothered by a chronic emotional state which made him look like a "weepy" woman. his eyes were always full of tears and his chin a-quiver, and he had, as he said, a perpetual lump in his throat. under re-education both lump and paralysis disappeared completely and mr. r. took his wife across the continent, driving his machine with his own hands--and feet. =a subconscious association.= mr. d.'s case admirably illustrates the return of symptoms through an unconscious association. he was a lawyer, prominent in public affairs of the middle west, who had been my patient for several weeks and who had gone home cured of many striking disabilities. before he came to me, he had given up his public work and was believed by all his associates to be afflicted with softening of the brain, and "out of the game" for good. from being one of the ablest men of his state, he had fallen into such a condition that he could neither read a letter nor write one. he could not stand the least sunshine on his head, and to walk half a mile was an impossibility. he was completely "down and out" and expected to be an invalid for the rest of his life. but these symptoms had one by one disappeared during his five-weeks stay with me. he had done good stiff work in the garden, carried a heavy sack of grapefruit a mile in the hot sun, and was generally his old self again. now he was back in the harness, hard at work as of old. suddenly, as he sat reading in his home one evening, all his old symptoms swept over him,--the pains in his head and legs, the pounding of the heart, the "all-gone" sensations as though he were going to die on the spot. he became almost completely dissociated, but through it all he clung to the idea which he had learned,--namely that this experience was not really physical as it seemed but was the result of some idea, and would pass. he did not tell any one of the attack, ignored it as much as possible, and waited. in a few minutes he was himself again. then he looked for the cause and realized that the article he was reading was one he had read several months previous, when suffering most severely from the whole train of symptoms. when the familiar words had again gone into his mind, they had pressed the button for the whole physiological experience which had once before been associated with them. this is the same mechanism as that involved in prince's case, miss beauchamp, who became completely dissociated at one time when a breeze swept across her face. when dr. prince looked for the cause, he found that once before she had experienced certain distressing emotions while a breeze was fanning her cheek. the recurrence of the physical stimulation had been sufficient to bring back in its entirety the former emotional complex. =another kind of association.= one of my women patients illustrates another kind of association-mechanism, based not on proximity in time but proximity of position in the body. this woman had complained for years of "bladder trouble" although no physical examination had been able to reveal any organic difficulty. she referred to a constant distress in the region of the bladder and was never without a certain red blanket which she wrapped around her every time she sat down. during psycho-analysis she recounted an experience of years before which she had never mentioned to anybody. during a professional consultation her physician, a married man, had suddenly seized her and exclaimed, "i love you! i love you!" in spite of herself, the woman felt a certain appeal, followed by a great sense of guilt. in the conflict between the physiological reflex and her moral repugnance, she had shunted out of consciousness the real sex-sensation and had replaced it with a sensation which had become associated in her subconscious mind with the original temptation. since the nerves from the genital region and from the bladder connect with the same segment of the spinal cord, she had unconsciously chosen to mix her messages, and to cling to the substitute sensation without being in the least conscious of the cause. as soon as she had described the scene to me and had discerned its connection with her symptoms, the bladder trouble disappeared. =afraid of the cold.= patients who are sensitive to cold are very numerous. mr. g.--he of the prunes and bran biscuits--was so afraid of a draft that he could detect the air current if a window was opened a few inches anywhere in a two-story house. he always wore two suits of underwear, but despite his precautions he had a swollen red throat much of the time. his prescription was a cold bath every morning, a source of delight to the other men patients, who made him stay in the water while they counted five. he was required to dress and live like other folks and of course his sensitiveness and his sore throat disappeared. dr. b----, when he came to me, was the most wrapped-up man i had ever met. he had on two suits of underwear, a sweater, a vest and suit coat, an overcoat, a bear-skin coat and a jaeger scarf--all in pasadena in may! besides this fear of cold, he was suffering from a hypersensitiveness of several other varieties. so sensitive was his skin that he had his clothes all made several sizes too big for him so that they would not make pressure. he was so aware of the muscles of the neck that he believed himself unable to hold up his head, and either propped it with his hands or leaned it against the back of a chair. he had been working on the eighth edition of his book, a scientific treatise of nation-wide importance, but his eyes were so sensitive that he could not possibly use them and had to keep them shaded from the glare. he was so conscious of the messages of fatigue that he was unable to walk at all, and he suffered from the usual trouble with constipation. all these symptoms of course belonged together and were the direct result of a wrong state of mind. when he had changed his mind, he took off his extra clothes, walked a mile and a half at the first try, gave up his constipation, and went back to work. later on i had a letter from him saying that his favorite seat was an overturned nail-keg in the garden and that he was thinking of sawing the backs off his chairs. miss y---had worn cotton in her ears for a year or two because she had once had an inflammation of the middle ear, and believed the membrane still sensitive to cold. there was miss e----, whose underwear always reached to her throat and wrists and who spent her time following the sun; and dr. i----, who never forgot her heavy sweater or her shawl over her knees, even in front of the fire. the procession of "cold ones" is almost endless, but always they find that their sensitiveness is of their own making and that it disappears when they choose to ignore it. =fear of light.= fear of cold is no more common than fear of light. nervous folk with half-shut eyes are very frequent indeed. from one woman i took at least seven pairs of dark glasses before she learned that her eye was made for light. a good example is furnished by a woman who was not a patient of mine at all, but merely the sister of a patient. after my patient had been cured of a number of distressing symptoms--pain in the spine, sore heels, a severe nervous cough, indigestion and other typical complaints,--she began to scheme to get her sister to come to me. this sister, the wife of a minister in the middle west, had a constant pain in her eyes, compelling her to hold them half-shut all the time. when she was approached about coming to me, she said indignantly, "if that doctor thinks that my trouble is nervous, she is much mistaken," and then proceeded to get well. once the subconscious mind gets the idea that its game is recognized, it is very apt to give it up, and it can do this without loss of time if it really wants to. =pain at the base of the brain.= of all nervous pains, that in the back of the neck is by all odds the most common. it is rare indeed to find a nervous patient without this complaint, and among supposedly well folk it is only too frequent. indeed, it almost seems that in some quarters such a pain stands as a badge of the fervor and zeal of one's work. but work is never responsible for this sense of discomfort. only an over-sensitiveness to feelings or a false emotionalism can produce a pain of this kind, unless it should happen to be caused by some poison circulating in the blood. the trouble is not with the nerves or with the spine, despite the fad about misplaced vertebrã¦. when a doctor examines a sensitive spine, marking the sore spots with a blue pencil, and a few minutes later repeats the process, he finds almost invariably that the spots have shifted. they are not true physical pains and they rarely remain long in the same place. pain in the spine and neck is an example of exaggerated sensibility or over-awareness. since all messages from every part of trunk and limb must go through the spinal cord, and since very many of them enter the cord in the region of the neck and shoulder blades, it is only natural that an over-feeling of these messages should be especially noticed in this zone. sometimes a false emotionalism adds to the discomfort by tensing the whole muscular system and making the messages more intense. when a social worker or a business man gets tense over his work or ties himself into knots over a committee meeting, he not only foolishly wastes his energy but makes his nerves carry messages that are more urgent than usual. then if he is on the look-out for sensations, he all the more easily becomes aware of the central station in the spine where the messages are received. by centering his attention on this station and tightening up his back-muscles, he increases this over-awareness and easily gets himself into the clutch of a vicious habit. sometimes a tenseness of the body is the result, not of a false attitude toward one's work, but of a lack of satisfaction in other directions. if the love-force is not getting what it wants, it may keep the body in a state of tension, with all the undesirable results of such tension. the person who keeps himself tense, whether because of his work or because of tension in other directions, has not really learned how to throw himself into his job and to forget himself, his emotions, and his body. =various pains.= tender spots may appear in almost any part of the body. there was the girl with the sore scalp, who was frequently so sensitive that she could not bear to have a single hair touched at its farthermost end, and who could not think of brushing her hair at such a time. there was the man whose wrists and ankles were so painful that the slightest touch was excruciating; the woman with the false sciatica; the man with the so-called appendicitis pains; and the man with the false neuritis, who always wore jersey coats several sizes too large. each one of these false pains was removed by the process of re-education. =low thresholds to fatigue.= mr. h. was habitually so overcome by fatigue that he could not make himself carry through the slightest piece of work, even when necessity demanded it. on sunday night, when there was no one else to milk the cow, he had had to stop in the middle of the process and go into the house to lie down. to carry the milk was impossible, so low were his thresholds to the slightest message of fatigue. it turned out that things were not going right in the reproductive life. his threshold was low in this direction, and it carried down with it all other thresholds. after a general revaluation of values, he found himself able to keep his thresholds at the normal level. a fine, efficient missionary from the orient had been so overcome with fatigue that he was forced to give up all work and return to this country. he had been with me for a while and was again ready to go to work. he came one day with a radiant face to bid me good-by. "why are you so joyous?" i asked. "because," he answered, "before i came home i was so fatigued that it used me up completely just to see the native servants pack our luggage. now we are taking back twice as much, and i not only packed it all myself but made the boxes with my own hands. no more fatigue for me!" a charming young girl who in many ways was an inspiration to all her associates fell into the habit of over-feeling her fatigue. "you know, doctor," she said, "that i give out too much of myself; everybody tells me so." that was just the trouble. everybody had told her so, and the suggestion had worked. it did not take her long to learn that in scattering abroad she was enriching herself, and that her "giving out" was not exhausting to her but rather the truest kind of self-expression. it is only when a "giving out" is accompanied by a "looking in" that it can ever deplete. the "see how much i am giving," and "how tired i shall be," attitude could hardly fail to exhaust, but a real self-expression and the fulfilment of a real desire to give are never anything else than exhilarating. there is something wrong with the minister who is used up after his sunday sermons. if his message and not himself is his real concern, he will have only a normal amount of fatigue, accompanied by a general sense of accomplishment and well-being, after he has fed his flock. to be sure, i have never been a minister, but i have had a goodly number among my patients and i speak from a fairly close acquaintance with their problems. =stopping our ears.= roosters seem to be a perpetual source of annoyance to the folk whose thresholds are not under proper control. but as roosters seem to be necessary to an egg-eating nation, it seems simpler to change the threshold than to abolish the roosters. there was one woman who complained especially about being disturbed by early-morning chanticleers. i explained that the crowing called for no action on her part, and that therefore she should not allow it to come into consciousness. "do you mean," she said, "that i could keep from hearing them?" as it happened, she was sitting under the clock, which had just struck seven. "did you hear the clock strike?" i asked. "no," she said; "did it strike?" this poor little woman, who suffered from a very painful back and other distressing symptoms, had been married at sixteen to a rouã© of forty; and, without experiencing any of the psychic feelings of sex, had been immediately plunged into the physical sex-relations. since sex is psycho-physical and since any attempt to separate the two elements is both desecrating and unsatisfactory; it is not surprising that misery, and finally divorce, had been her portion. another equally unpleasant experience had followed, and the poor woman in the strain and disappointment of her love-life, and in the lowering of the thresholds pertaining to this thwarted instinct, had unconsciously lowered the thresholds to all physical stimuli, until she was no longer master of herself in any line. when she saw the reason for her exaggerated reactions, she was able to gain control of herself, and to find outlet in other ways. too many persons fall into the way of being disturbed by noises which are no concern of theirs. as nurses learn to sleep through all sounds but the call of their own patients, so any one may learn to ignore all sounds but those which he needs to hear. connection with the outside world can be severed by a mental attitude in much the same way as this is accomplished by the physical effect of an anaesthetic. then the usual noises, those which the subconscious recognizes as without significance, will be without power to disturb. the well-known new york publisher who spent his last days on his private yacht, on which everything was rubber-heeled and velvet-cushioned, thought that he couldn't stand noises; but how much more fun he would have had, if some one had only told him about thresholds! summary there are two kinds of people in the world,--masters and puppets. there is the man in control of his thresholds, at leisure from himself and master of circumstance, free to use his energy in fruitful ways; and there is the over-sensitive soul, wondering where the barometer stands and whether people are going to be quiet, feeling his feelings and worrying because no one else feels them, forever wasting his energy in exaggerated reactions to normal situations. this "ticklish" person is not better equipped than his neighbor, but more poorly equipped. true adjustment to the environment requires the faculty of putting out from consciousness all stimuli that do not require conscious attention. the nervous person is lacking in this faculty, but he usually fails to realize that this lack places him in the class of defectives. a paralyzed man is a cripple because he cannot run with the crowd; a nervous individual is a cripple, but only because he thinks that to run with the crowd lacks distinction. something depends on the accident of birth, but far more depends on his own choice. understanding, judicious neglect of symptoms, whole-souled absorption in other interests, and a good look in the mirror, are sure to put him back in the running with a wholesome delight in being once more "like folks." chapter xv _in which we learn discrimination_ choosing our emotions liking the taste it was a summer evening by the seaside, and a group of us were sitting on the porch, having a sort of heart-to-heart talk about psychology,--which means, of course, that we were talking about ourselves. one by one the different members of the family spoke out the questions that had been troubling them, or brought up their various problems of character or of health. at length a splendid red cross nurse who had won medals for distinguished service in the early days of the war, broke out with the question: "doctor, how can i get rid of my terrible temper? sometimes it is very bad, and always it has been one of the trials of my life." she spoke earnestly and sincerely, but this was my answer: "you like your temper. something in you enjoys it, else you would give it up." her face was a study in astonishment. "i don't like it," she stammered; "always after i have had an outburst of anger i am in the depths of remorse. many a time i have cried my eyes out over this very thing." "and you like that, too," i answered. "you are having an emotional spree, indulging yourself first in one kind of emotion and then in another. if you really hated it as much as you say you do, you would never allow yourself the indulgence, much less speak of it afterward." her astonishment was still further increased when several of the group said they, too, had sensed her satisfaction with her moods. hard as it is to believe, we do choose our emotions. we like emotion as we do salt in our food, and too often we choose it because something in us likes the savor, and not because it leads to the character or the conduct that we know to be good. the power of choice whether we believe it or not, and whether we like it or not, the fact remains that we ourselves decide which of all the possible emotions we shall choose, or we decide not to press the button for any emotion at all. to a very large extent man, if he knows how and really wishes, may select the emotion which is suitable in that it leads to the right conduct, has a beneficial effect on the body, adapts him to his social environment, and makes him the kind of man he wants to be. =the test of feeling.= the psychologist to-day has a sure test of character. he says in substance: "tell me what you feel and i will tell you what you are. tell me what things you love, what things you fear, and what makes you angry and i will describe with a fair degree of accuracy your character, your conduct, and a good deal about the state of your physical health." since this test of emotion is fundamentally sound, it is not surprising that the nervous man is in a state of distress. indigestion, fatigue, over-sensibility, sound like problems in physiology, but we cannot go far in the discussion of any of them without coming face to face with the emotions as the real factors in the case. when we turn to the mental characteristics of nervous folk, we even more quickly find ourselves in the midst of an emotional disturbance. worried, fearful, anxious, self-pitying, excitable, or melancholy, the nervous person proves that whatever else a neurosis may be, it is, in essence, a riot of the emotions. there is small wonder that a riot at the heart of the empire should lead to insurrection in every province of the personality. it is only for the purpose of discussion that we can separate feeling from thinking and doing. every thought and every act has in it something of all three elements. an emotion is not an isolated phenomenon; it is bound up on the one hand with ideas and on the other with bodily states and conduct. whoever runs amuck in his emotions runs amuck in his whole being. the nervous invalid with his exhausted and sensitive body, his upset mind and irrational conduct is a living illustration of the central place of the emotions in the realm of the personality. but it is not the nervous person only who needs a better understanding of his emotional life. the well man also gets angry for childish reasons; he is prejudiced and envious, unhappy and suspicious for the very same reason as is the nervous man. since the working-capital of energy is limited to a definite amount, the control of the emotions becomes a central problem in any life,--a deciding factor in the output and the outcome, as well as in comfort and happiness by the way. nothing is harder for the average man to believe than this fact that he really has the power to choose his emotions. he has been dissatisfied with himself in his past reactions, and yet he has not known how to change them. his anger or his depression has appeared so undesirable to his best judgment and to his conscious reason that it has seemed to be not a part of himself at all but an invasion from without which has swept over him without his consent and quite beyond control. a house divided against itself most of the confusion comes from the fact that we know only a part of ourselves. what we do not consciously enjoy we believe we do not enjoy at all. what we do not consciously choose we believe to be beyond our power of choice,--the work of the evil one, or the natural depravity of human nature, perhaps; but certainly not anything of our choosing. the point is that a human being is so constituted that he can, without knowing it, entertain at the same time two diametrically opposite desires. the average person is not so unified as he believes, but is, in fact, "a house divided against itself." the words of the apostle paul express for most of us the truth about ourselves: "for what i would, that i do not; but what i hate that i do." what paul calls the law of his members warring against the law of his mind is simply what we call to-day the instinctive desires coming into conflict with our conscious ideal. =hidden desires.= although we choose our emotions, we choose in many cases in response to a buried part of ourselves of which we are wholly unaware, or only half-aware. when we do not like what we have chosen, it is because the conscious part of us is out of harmony with another part and that part is doing the choosing. if the emotions which we choose are not those that the whole of us--or at least the conscious--would desire, it is because we are choosing in response to hidden desires, and giving satisfaction to cravings which we have not recognized. repeated indulgence of such desires is responsible for the emotional habits which we are too likely to consider an inevitable part of our personality, inherited from ancestors who are not on hand to defend themselves. when we form the habit of being afraid of things that other people do not fear, or of being irritated or depressed, or of giving way to fits of temper, it is because these habit-reactions satisfy the inner cravings that in the circumstances can get satisfaction in no better way. these hidden desires are of several different kinds, when squarely looked at. some of the cravings are found to be childish, and so out of keeping with our real characters that we could not possibly hold on to them as conscious desires. others turn out to be so natural and so inevitable that we wonder how we could ever have imagined that they ought to be repressed. still others, legitimate in themselves, but denied because of outer circumstances, are found to be easily satisfied in indirect ways which bear no resemblance to their old unfortunate forms of outlet. when knowledge helps the way to get rid of an undesirable emotion is not by working at the emotion itself, but by realizing that this is merely an offshoot of a deeper root, hidden below the surface. the great point is to recognize this deeper root. =childish anger.= it helps to know that uncalled-for anger is a defense reaction--a sort of camouflage or smoke cloud which we throw out to hide from ourselves and others the fact that we are being worsted in an argument, or being shown up in an undesirable light. better than any amount of weeping over a hot temper is an understanding of the fact that when we fly into unseemly rage we are usually giving indulgence to a childhood desire to run away from unpleasant facts and to cover up our own faults. =enjoying the blues.= it helps to know that the easiest way to fight the blues is by realizing that they are a deliberate, if unconscious, attempt to gain the pity of ourselves and others. there seems to be in undeveloped human nature something that really enjoys being pitied, and if we cannot get the commiseration of other people, we can, without much trouble, work up a case of self-pity. most of us would have to acknowledge that we seldom find tears in our eyes except when our own woes are under consideration. "whatever else the blues accomplish, they certainly afford us a chance to submerge ourselves in a sea of self-engrossment."[63] [footnote 63: putnam: _human motives_.] =the chip on the shoulder.= it helps to know that irritability and over-sensitiveness are usually the result of tension from unsatisfied desires which must find some kind of outlet. if a person is secretly restive under the fact that he cannot have the kind of clothes he wants, cannot shine in society, or secure a college education or a large fortune,--all of which minister to our insistent and rarely satisfied instinct of self-assertion,--or if he is secretly yearning for the satisfaction of the marriage relation, or for the sense of completion in parenthood; then the tension from these unsatisfied desires shows itself in a hundred little everyday instances of lack of self-control. these mystify him and his friends, but they are understandable when the whole truth is known. =anxiety and fear.= nowhere is understanding more valuable than when we approach the subject of anxiety and fear. whenever a person falls into a state of abnormal fear, his friends and his physician spend a good deal of time in attempting to prove to him that there is no cause for apprehension, and in exhorting him to use his reason and give up his fear. but how can a person help himself when he is fighting in the dark? how can he free himself when the thing he thinks he fears is merely a symbol of what he really fears? the woman who was afraid she would choke her child had been several months in the hands of christian scientists, and had earnestly tried to replace fear with courage. but in the circumstances, and without further knowledge, this was as impossible as it is for a man to lift himself by his own boot-straps. she had no point of contact with her real fear, as the man has no leverage contact with the earth from which he wishes to lift himself. to be sure there are many cases in which an assumed cheerfulness and courage do have a mighty effect on the inner man. the forces of the personality are not set, but plastic, and are constantly acting and interacting upon one another. surface habits do influence the forces below the surface. william james's advice, "square your shoulders, speak in a major key, smile, and turn a compliment," is good for most occasions, but sometimes even a little understanding of the cause is far more effective. it helps to know that persistent anxiety, lacking obvious cause, is found to be the anxiety of the thwarted instinct of reproduction. when the sex-instinct is repeatedly stimulated and then checked it sets in motion some of the same glands that are activated in fear. what comes up into consciousness is therefore very naturally a fear or dread of impending disaster, very like the poignant anxiety that one feels when stepping up in the dark to a step that is not there. simultaneous with the fear lest these repressed desires should not be satisfied, there is an intense fear lest they should. the more insistent the repressed desire, and the more it seems likely to break through into consciousness, the keener the anguish of the ethical impulses. abnormal fear, however it may seem to be externalized, always implies at the bottom a fear of something within. there is no truth which is harder to believe on first hearing but which grows more compelling with further knowledge, than this truth that an exaggerated fear always implies a desire which somehow offends the total personality. when we observe the various distressing phobias, such as the common fear of contamination, a woman's fear to undress at night, a fear that the gas was not turned off, or that one's clothing is out of order; fear lest the exact truth has not been told, or that the uttermost farthing of one's obligations has not been met,--then we may know that there is something in the fear situation which either directly or symbolically refers to some hidden desire; a desire which the individual would not for the world acknowledge to himself, but which is too keen to be altogether repressed. the close connection between fear and desire is often shown in the unfounded fear of having committed a crime. both doctors and lawyers in their professional work occasionally come upon individuals who believe that they have committed some heinous crime of which they are really innocent, and who insist upon their guilt despite all evidence to the contrary. a quiet, gentle youth who at the age of twenty was under my medical care, is still not sure in his own whether he, at twelve years of age, was the burglar who broke into the village store and killed the owner. it is difficult for the normally self-satisfied individual to understand the appeal of heroics to a person whose starved instinct of self-assertion makes him choose to be known as a villain rather than not to be known at all. =breaking the spell.= when once we bring up into consciousness these hidden desires that manifest themselves in such troublesome ways, we find that we have robbed them of much of their power over our lives. sometimes, it is true, a detailed and thorough exploration by psycho-analysis is necessary, but in many cases it is sufficient just to know that there are underlying causes. to know these things is far from excusing ourselves because of them. even though emotions are determined by forces that are deep in the subconscious, we may still choose in opposition to those forces, if we but know that we can do so. the fact that some of the roots of our bad habits reach down into the subconscious is no excuse for not digging them up. as dr. putnam says, "it is the whole of us that acts, and we are as responsible for the supervision of the unseen as for the obvious factors that are at work. the moon may be only half illumined and half visible, but the invisible half goes on, none the less, exerting its full share of influence on the motion of the tides and earth."[64] [footnote 64: putnam: _freud's psychoanalytic method and its evolution_, p. 34.] the highest kind of choice there is no easier way to enliven any conversation than by dropping the remark that a human being always does what he wants to do. simple as the statement seems, it is quite enough to quicken the dullest table-talk and loosen the most reticent tongue. "i don't do what i want to do," says the college student. "i want to play tennis every afternoon; but what i do is to sit in a stuffy room and study." "i don't do what i want to do," says the mother of a family. "at night i want to sit down and read the latest magazine, but what i do is to darn stockings by the hour." nevertheless we shall see that, even in cases like these, each of us is acting in accordance with his strongest desire. there may be--there often is--a bitter conflict, but in the end the desire that is really stronger always conquers and works itself out into action. it is possible to imagine a situation in which a man would be physically unable to do what he wanted to do. bound by physical cords, held by prison walls, or weakened by illness, he might be actually unable to carry out his desires. but apart from physical restraint, it is hard to imagine a situation in real life in which a person does not actually do what he wants to do; that is, what _in the circumstances he wants to do_. this is simply saying in another way that we act in accordance with the emotion which is at the moment strongest. =will is choice.= just here we can imagine an earnest protest: "but why do you ignore the human will? why do you try to make man the creature of feeling? a high-grade man does--not what he wants to do but what he thinks he ought to do. in any person worthy of the adjective 'civilized' it is conscience, not desire, which is the motive power of his life." it is true: in the better kind of man the will is of central importance; but what is "will"? let us imagine a raw soldier in the trenches just before a charge into no-man's land. he is afraid, but the word of command comes, and instantly he is a new creature. his fear drops away and, energized by the lust of battle, he rushes forward, obviously driven by the stronger emotion. he goes ahead because he really wants to, and we say that he does not have to use his will. imagine another soldier in the same situation; with him fear seems uppermost. his knees shake and his legs want to carry him in the wrong direction, but he still goes forward. and he goes forward, not so much because there is no other possibility as because, in the circumstances, he really wants to. all his life, and especially during his military training, he has been filled with ideals of loyalty and courage. more than he fears the guns of the enemy or of his firing-squad does he fear the loss of his own self-respect and the respect of his comrades. greater than his "will to live" is his desire to play the man. there is conflict, and the desire which seems at the moment weaker is given the victory because it is reinforced by that other permanent desire to be a worthy man, brave, and dependable in a crisis. he goes forward, because in the circumstances, he really wants to, but in this case we say that he had to use his will. is it not apparent that will itself is choice,--the selection by the whole personality of the emotion and the action which best fit into its ideals? will is choice by the part of us which has ideals. mcdougall points out that will is the reinforcement of the weaker desire by the master desire to be a certain kind of a character.[65] [footnote 65: "the essential mark of volition is that the personality as a whole, or the central feature or nucleus of the personality, the man himself, is thrown upon the side of the weaker motive."--mcdougall: _introduction to social psychology_, p. 240.] each human being as he goes through life acquires a number of moral ideals and sentiments which he adopts as his own. they become linked with the instinct of self-assertion, which henceforth acts as the motive power behind them, and attempts to drive from the field any emotion which happens to conflict. men, like the lower animals, are ruled by desire, but, as g.a. coe says, "men mold themselves. they form desires not merely to have this or that object, but to be this or that kind of a man."[66] [footnote 66: coe: _psychology of religion_.] if a man be worthy of the name, he is not swayed by the emotion which happens for the moment to be strongest. he has the power to reinforce and make dominant those impulses which fit into the ideal he has built for himself. in other words, he has the power to choose between his desires, and this power depends largely upon the ideals which he has incorporated into his life by the complexes and sentiments which compose his personality. _ideas and ideals_. if emotion is the heart of humanity, ideas are its head. in our emphasis on emotion, we must not forget that as emotion controls action, so ideas control emotion. but ideas, of themselves, are not enough. everybody has seen weaklings who were full of pious platitudes. ideas do control life, but only when linked up with some strong emotion. no moral sentiment is strong enough to withstand an intense instinctive desire. if ideas are to be dynamic factors in a life, they must become ideals and be really desired. they must be backed up by the impulse of self-assertion, incorporated with the sentiment of self-regard, and so made a permanent part of the central personality. parents and teachers who try to "break a child's will" and to punish every evidence of independence and self-assertion little know that they are undermining the foundations of morality itself, and doing their utmost to leave the child at the mercy of his chance whims and emotions. there can be no strength of character without self-regard, and self-regard is built on the instinctive desire of self-assertion. =education and religion.= it is easy to see how important education is in this process of giving the right content to the self-regarding sentiment. the child trained to regard "temper" as a disgrace, self-pity as a vice, over-sensitiveness as a sign of selfishness, and all forms of exaggerated emotionalism as a token of weakness, has acquired a powerful weapon against temptation in later life. indulgence in any of these forms of gratification he will regard as unworthy and out of keeping with his personality. it is easy, too, to see how central a place a vital religious faith has in enriching and ennobling the ego-ideal, and in giving it driving-power. a force which makes a high ideal seem both imperative and possible of achievement could hardly fail to be a deciding factor. every student of human nature knows in how many countless lives the christian religion has made all the difference between mere good intentions and the power to realize those intentions; how many times it has furnished the motive power which nothing else seemed able to supply. moral sentiments which have been merely sentiments become, through the magic of a new faith, incorporated into conscience and endowed with new power. just here lies the value of any great love, or any intense devotion to a cause. as royce says: "to have a conscience, then, is to have a cause; to unify your life by means of an ideal determined by this cause, and to compare this ideal and the life."[67] [footnote 67: royce: _philosophy of loyalty_, p. 175.] =avoiding the strain.= it seems that a human being is to a large extent controlled by will, and that will is in itself the highest kind of choice. but too often will is crippled because it does not speak for the whole personality. knowledge helps a person to relate conscience with hitherto hidden parts of himself, to assert his will, and to choose only those emotions and outlets which the connected-up, the unified personality wants. sometimes, indeed, a little knowledge makes the exercise of the will power unnecessary. using will power is, after all, likely to be a strenuous business. it implies the presence of conflict, and the strain of defeating the desire which has to be denied.[68] why struggle to subdue emotional bad habits when a little insight dispels the desire back of them, and makes them melt away as if by magic? for example, why use our will to keep down fear or anger when a little understanding dissipates these emotions without effort? [footnote 68: freud: _introduction to psychoanalysis_, p. 42.] whatever we do with difficulty we are not doing well. when it requires effort to do our duty this means that a great part of us does not want to do it. when we get rid of our hidden resistances we work with ease. as a strong wind, applied in the right way, drives the ship without effort, just so the forces in our lives, if they are adjusted to one another, will without strain or stress easily and naturally work together to carry us in the direction we have chosen. when we get rid of blind conflicts, even the business of ruling our spirits becomes feasible. summary =various "sprees."= the human animal has a constitutional dislike for dullness and will seize upon almost any device which promises to lift him out of what he considers the monotony of daily grind. an elaborate essay might be written on the means which human beings have taken to create the sense of _aliveness_ which they so much crave. some of them--we call them savages--have found satisfactory certain wild orgies in primitive war-dances; others--we shall soon call them "out of date"--have found simpler a bottle of whisky or a glass of champagne; still others find a cold shower more invigorating, or a brisk walk or a good stiff job which sets them aglow with the sense of accomplishment. but there are always those who, for one reason or another, find most satisfactory of all a chronic emotional tippling, or a good old-fashioned emotional spree. persons who would be shocked at the idea of whisky or champagne allow themselves this other kind of indulgence without in the least knowing why. nor is the connection between alcoholism and emotionalism so far-fetched as it seems. psycho-analytic investigations have repeatedly revealed the fact that both are indulged in because they remove inhibitions, give vent to repressed desires, and bring a sense of life and power which has somehow been lost in the normal living. both kinds of spree are followed by the inevitable "morning after" with its proverbial headache, remorse, and vows of repentance but despite all this, both are clung to because the satisfaction they bring is too deep to be easily relinquished. whenever an emotion quite out of keeping with conscious desire is allowed to become habitual, we may know that it is being chosen by a part of the personality which needs to be uncovered and squarely faced. nervous symptoms and exaggerated emotionalism are alike evidence of the fact that the wrong part of us is doing the choosing and that the will needs to be enlightened on what is taking place in the outer edge of its domain. in the choice between emotionalism and equanimity, the selection of the former can only be in response to unrecognized desire. a nervous person is invariably an emotional person, and as a rule lays the blame for his condition upon past experiences. but experience is what happens to us _plus_ the way we take it. we cannot always ward off the blow, but we can decide upon our reaction. "even if the conduct of others has been the cause of our emotion, it is really we ourselves who have created it by the way in which we have reacted."[69] [footnote 69: dubois: _psychic treatment of nervous disorders_, p. 155.] one ship drives east, another drives west, while the self-same breezes blow; 'tis the set of the sail, and not the gale that bids them where to go. like the winds of the sea are the ways of fate, as we journey along through life; 'tis the set of the soul that decides the goal, and not the calm or the strife. rebecca r. williams. chapter xvi _in which we find new use for our steam_ finding vent in sublimation the re-direction of energy a child pent up on a rainy day is a troublesome child. his energy keeps piling up, but there is no opportunity for him to expend it. the nervous person is just such a pent-up child. a portion of his personality is developing steam which goes astray in its search for vent; this portion is found to be the psychic side of his sex-life. something has blocked the satisfactory achievement of instinctive ends and turned his interest in on himself. perhaps he does not come into complete psychic satisfaction of his love-life because his wife is out of sympathy or is held back by her own childish repressions. perhaps his love-instinct is baffled by finding itself thwarted in its purpose of creating children, restrained by the social ban and the desire for a luxurious standard of living. perhaps he is jealous of his chief, or of an older relative whose business stride he cannot equal. jung has pointed out how frequently introversion or turning in of the life-force is brought about by the painfulness of present reality and by the lack of the power of adaptation to things as they are. but this lack always has its roots in childhood. the woman who is shocked at the thought of sex is the little girl who reacted too strongly to early impressions. the man of forty who is disgruntled because he is not made manager of a business created by others is the little boy who was jealous of his father and wanted to usurp his place of power. the man who suffers from a sense of inferiority because his friend has a handsomer or more intellectual wife is the same little boy who strove with his father for possession of the mother, the most desired object in his childish environment. the measure of escape from these childish attitudes means the measure of success in life. fortunately for society, the average person achieves this success. the normal person in his childhood learned how to switch the energy of his primitive desires into channels approved by society. stored away in his subconscious, this acquired faculty carries him without conscious effort through all the necessary adjustments in maturity. the nervous person, less well equipped in childhood, may fortunately acquire the faculty in all its completeness, although at the cost of genuine effort and patient self-study. =sublimation the key word.= in the prevention and in the cure of nervous disorders there is one factor of central importance, and that factor is sublimation--or the freeing of sex-energy for socially useful, non-sexual ends. to sublimate is to find vent for oneself and to serve society as well; for sublimation opens up new channels for pent-up energy, utilizing all the surplus of the sex-instinct in substitute activities. when the dynamic of this impulse is turned outward, not inward, it proves to be one of man's greatest possessions, a valuable contribution of energy to creative activities and personal relationships of every kind. =the failure to sublimate.= a neurosis is nonconstructive use of one's surplus steam. the trouble with a nervous person is that his love-force is turned in on himself instead of out into the world of reality. this is what his friends mean when they say that he is self-absorbed; and this is what the psychologists mean when they say that a neurotic is introverted. a person, in so far as he is nervous, does not see other people at all--that is, he does not see them as real persons, but only as auditors who may be made to listen to the tale of his woes. his own problems loom so large that he becomes especially afflicted with what cabot calls "the sin of impersonality"; or to use president king's words, he lacks that "reverence for personality" which enables one to see people vividly as real persons and not as street-car conductors or servants or merely as members of one's family. to be sure, many a so-called normal individual is afflicted with this same kind of blindness; here as elsewhere the neurotic simply exaggerates. engrossed in his own mental conflicts and physical symptoms, he is likely to find his interest withdrawing more and more from other people and centering upon himself. =sublimation and religion.= we do not need psychology to tell us that engrossment in self is a disastrous condition. when the psycho-analyst says that the life-force must be turned out, not in, he is approaching from a new angle the truth as it is found in the gospel,--"thou shalt love the lord thy god with all thy heart," and "thy neighbor as thyself." religion provides the love-object in the creator; altruism provides it in the "neighbor." christianity and psychology agree that as soon as love ceases to be an outgoing force, just so soon does the individual become an incomplete and disrupted personality.[70] [footnote 70: for emphasis on religion as a means to sublimation, see freud, putnam, pfister, james, and dubois.] =carlyle's doctrine of work.= "produce! produce! produce!" life for a social being involves not only rich personal relationships, but absorbing, creative work. no nervous person is cured until he is willing to take and to keep a "man-size job." a good piece of work is not only the sign of a cure; it is the final step without which no cure is complete. =along nature's lines.= if the psychologist is asked what kind of task this is to be, he answers that each person must decide for himself his own life-work. an individual may not know why, but he does know that there are certain things which he most likes to do. sublimation is more readily accomplished if his energy is directed toward self-chosen interests. parents or teachers or physicians who try to force another person into any definite plan of action are making a grievous blunder. help may be given toward self-knowledge and the understanding of general principles, but advice should never be specific. taken in the large, it is found that men and women choose different ways of sublimation. man and woman differ in the psychic components of the sex-life even as they differ in the physical. sublimation to be successful must follow the lines laid down by nature. the urge of the average man is toward construction, domination, mastery. the urge of the average woman is toward mothering, protection, nurture. the masculine characteristics find ready sublimation in a career; the man builds bridges, digs canals, harnesses mountain streams, conquers pests, overcomes gravity, brings the ends of the earth together by "wireless" or by rail; he provides for the weak and the helpless--his own progeny--or, incarnated in the body of a hoover, he gives life to the children of the world. in woman, the dominant force is the nurturing instinct. child and man of her own come first, but when these are lacking, to paraphrase kipling, in default of closer ties, she is wedded to convictions; heaven help him who denies! only as a career opens up full vent for this nurturing instinct, will it provide satisfactory substitute in sublimation. its natural trend can be seen in the recent tidal wave of social legislation--for prohibition, child-labor laws, sanitation, recognition and control of venereal disease, acknowledgment of paternity to the illegitimate child. since the women of the day, in numbers up to the million, have been compelled to sacrifice both man and unformed babe to the grim juggernaut of war, this nurturing urge may press hard against many of the social and business barriers now impeding its flow. but if society understands and readjusts these barriers, making it possible for its citizens--women as well as men--to approximate the natural instinctive bent, it will not only save itself much unrest but will also go far toward preventing the spread of nervous invalidism. summary that which a nervous invalid most needs is a redirection of energy. since, in spite of appearances, there is never any real lack of energy, no time is needed for the making of strength, and a cure can take place just as soon as the inner forces allow the energy to flow out in the right direction. sometimes, indeed, an outer change may start the inner process. often the "work cure" does cure; occasionally the sudden necessity to earn one's living or to mother a little child frees the life-force from its old preoccupation and forces it into other channels. in most cases, however, the nervous invalid is suffering not from lack of opportunities for outside interest but from an inner inability to meet the opportunities which present themselves. the great change that has to be made is not in external conditions and habits but in the hidden corners of the mind; a change that can be accomplished only by self-knowledge and re-education. but if self-knowledge is the first step in any cure, so self-giving must be the final step. sooner or later in the life of every nervous invalid there comes a time when nothing will serve to unify his disorganized forces but steady and unswerving responsibility for a good stiff piece of work. happy for him that this is so and that he is living in a day when science no longer tells him to fold his hands and wait. glossary _autonomic nervous system:_ the vegetative nervous system which controls vital functions,--as digestion, respiration, circulation. _censor:_ a hypothetical faculty of the fore-conscious mind which resists the emergence into consciousness of questionable desires. _common path:_ in physiology, the final route over which response is made to physical stimulation;

with the diseases to which they are subject, and the remedies best adapted to their cure. to which is added a list of the medicines used in treating cattle. by robert jennings, v. s., professor of pathology and operative surgery in the veterinary college of philadelphia; late professor of veterinary medicine in the agricultural college of ohio; secretary of the american veterinary association of philadelphia; author of "the horse and his diseases," etc., etc. [illustration: with numerous illustrations.] philadelphia: john e. potter and company, 617 sansom street. entered according to act of congress, in the year 1864, by john e. potter, in the clerk's office of the district court of the united states, in and for the eastern district of pennsylvania. preface. a marked interest has of late years been manifested in our country relative to the subject of breeding and rearing domestic cattle. this has not been confined to the dairyman alone. the greater portion of intelligent agriculturists have perceived the necessity of paying more attention than was formerly devoted to the improvement and perfection of breeds for the uses of the table as well. in this respect, european cattle-raisers have long taken the precedence of our own. the gratifying favor with which the author's former publication, "the horse and his diseases," has been received by the public, has induced him to believe that a work, similar in spirit and general treatment, upon cattle, would not be without interest for the agricultural community. in this belief, the present treatise has been prepared. the author has availed himself of the labors of others in this connection; never, however, adopting results and conclusions, no matter how strongly endorsed, which have been contradicted by his own observation and experience. in a field like the one in question, assuredly, if anywhere, some degree of independent judgment will not be censured by those who are familiar with the sad consequences resulting from the attempted application of theories now universally exploded, but which in the day and generation of their originators were sanctioned and advocated by those who claimed to be magnates in this department. to the following works, especially, the author acknowledges himself indebted: american farmer's encyclopædia; stephens's book of the farm; flint's milch-cows and dairy farming; laurence on cattle; allen's domestic animals; youatt and martin on cattle; thomson's food of animals; allen's rural architecture; colman's practical agriculture and rural economy; goodale's breeding of domestic animals; and prof. gamgee's valuable contributions to veterinary science. particular attention is requested to the division of "diseases." under this head, as in his former work, the author has endeavored to detail the symptoms of the most common ailments of cattle in such a manner that every farmer and cattle-owner can at once understand them, and also to suggest such procurable remedies as a wide experience has proved to be most efficacious. a generous space has been devoted to the consideration of that fatal epidemic, now generally known as "pleuro-pneumonia," as it has manifested itself in europe and this country, in the belief that a matter of such vital importance to the stock-raiser ought to receive a complete exposition in a work like the present. as the author's personal experience in connection with the treatment of this peculiar disease has been, perhaps, as large and varied as that of any american practitioner, he is not without the hope that his views upon the matter may prove productive of some benefit to others. should the present volume prove as acceptable to those interested as did his former work, the author will be abundantly satisfied that he has not mistaken in this instance the wants of the public. contents. history and breeds of cattle, 13 the british ox, 15 american cattle, 21 the ayrshire, 23 the jersey, 30 the short-horns, 32 the dutch, 36 the hereford, 38 the north-devon, 41 native cattle, 43 natural history of cattle, 50 gestation, 51 formation of teeth, 51 points of a good cow, 57 the milk-mirror, 61 crossing and breeding, 77 pregnancy, 92 treatment before calving, 93 feeding and management, 97 soiling, 118 culture of grasses for fodder, 122 the barn, 146 milking, 155 raising of calves, 168 points of fat cattle, 183 driving and slaughtering, 188 diseases and their remedies, 205 abortion, 206 apoplexy, 215 black-water, 215 bronchitis, 216 consumption, 217 coryza, 217 cow-pox, 218 diarrhoea, 219 dysentery, 220 enteritis, 222 epizoötics, 224 epizoötic catarrh, 234 fardel, 236 foul in the foot, 237 garget, 237 gastro-enteritis, 238 hoose, 238 hoove, 239 hydatids, 240 inflammation of the bladder, 241 inflammation of the haw, 241 inflammation of the kidneys, 242 inflammation of the liver, 242 laryngitis, 243 lice, 244 mange, 244 murrain, 246 navel-ill, 247 obstructions in the oesophagus, 247 open joints, 248 parturition, 248 free martins, 251 cleansing, 253 inversion of the uterus, 253 phrenitis, 254 pleurisy, 255 pleuro-pneumonia, 256 pneumonia, 300 protrusion of the bladder, 302 puerperal fever, 302 quarter evil, 303 rabies, 304 red water, 305 rheumatism, 307 strangulation of the intestines, 308 thrush in the mouth, 308 tumors, 308 ulcers about the joints, 312 warbles, 313 worms, 315 worms in the bronchial tubes, 316 surgical operations, 316 castration, 316 tracheotomy, 319 spaying, 320 list of medicines used in treating cattle, 330 doses of various medicines, 336 illustrations. page a prize bull, 13 the well-fed beasts, 19 an ayrshire bull, 23 a short-horn bull, 33 a north devon steer, 41 draft oxen, 45 skeleton of the ox, 50 teeth at birth, 52 teeth at second week, 52 teeth at three weeks, 53 teeth at a month, 53 teeth at five to eight months, 53 ten months teeth, 53 twelve months teeth, 54 fifteen months teeth, 54 eighteen months teeth, 55 teeth at two years past, 55 teeth at three years past, 56 teeth at four years past, 56 teeth at five years past, 56 teeth at ten years past, 56 a good milch cow, 58 milk-mirror (a), 62 milk-mirror (b), 63 milk-mirror (c), 63 milk-mirror (d), 64 milk-mirror (e), 65 milk-mirror (f), 66 milk-mirror (g), 69 milk-mirror (h), 70 milk-mirror (k), 72 milk-mirror (l), 74 cow and calf, 77 ready for action, 83 a sprightly youth, 89 feeding, 97 the family pets, 102 buying cattle, 107 calling in the cattle, 112 "on the rampage", 117 patiently waiting, 123 a chance for a selection, 129 a west highland ox, 139 barn for thirty-four cows and three yoke of oxen, 150 transverse section, 152 room over the cow-room, 153 the preferable method, 159 maternal affection, 168 frolicksome, 177 points of cattle, 185 a frontispiece, 190 scotch mode of cutting up beef, 195 english mode of cutting up beef, 197 diseases and their remedies, 205 a chat on the road, 218 the mad bull, 230 an aberdeenshire polled bull, 244 taking an observation, 256 the twins, 268 a rural scene, 285 taking it easily, 299 home again, 313 [illustration] history and breeds it is quite certain that the ox has been domesticated and in the service of man from a very remote period. we are informed in the fourth chapter of genesis, that cattle were kept by the early descendants of adam; jubal, the son of lamech--who was probably born during the lifetime of adam--being styled the father of such as have cattle. the ox having been preserved by noah from the flood of waters, the original breed of our present cattle must have been in the neighborhood of mount ararat. from thence, dispersing over the face of the globe--altering by climate, by food, and by cultivation--originated the various breeds of modern ages. that the value of the ox tribe has been in all ages and climates highly appreciated, we have ample evidence. the natives of egypt, india, and hindostan, seem alike to have placed the cow amongst their deities; and, judging by her usefulness to all classes, no animal could perhaps have been selected whose value to mankind is greater. the traditions, indeed, of every celtic nation enroll the cow among the earliest productions, and represent it as a kind of divinity. in nearly all parts of the earth cattle are employed for their labor, for their milk, and for food. in southern africa they are as much the associates of the caffre as the horse is of the arab. they share his toils, and assist him in tending his herds. they are even trained to battle, in which they become fierce and courageous. in central africa the proudest ebony beauties are to be seen upon the backs of cattle. in all ages they have drawn the plough. in spain they still trample out the corn; in india they raise the water from the deepest wells to irrigate the thirsty soil of bengal. when cæsar invaded britain they constituted the chief riches of its inhabitants; and they still form no inconsiderable item in the estimate of that country's riches. the parent race of the ox is said to have been much larger than any of the present varieties. the urus, in his wild state at least, was an enormous and fierce animal, and ancient legends have thrown around him an air of mystery. in almost every part of the continent of europe and in every district of england, skulls, evidently belonging to cattle, have been found, far exceeding in bulk any now known. as the various breeds of cattle among us were introduced into this country from great britain, we propose, before going into the details of the leading american breeds, to glance somewhat briefly at the history of the british ox. in the earliest and most reliable accounts which we possess of the british isles--the commentaries of cæsar--we learn that the ancient britons possessed great numbers of cattle. no satisfactory description of these cattle occurs in any ancient author; but, with occasional exceptions, we know that they possessed no great bulk or beauty. cæsar tells us that the britons neglected tillage and lived on milk and flesh; and this account of the early inhabitants of the british isle is corroborated by other authors. it was such an occupation and mode of life as suited their state of society. the island was divided into many little sovereignties; no fixed property was secure; and that alone was valuable which could be hurried away at the threatened approach of the invader. many centuries after this, when--although one sovereign seemed to reign paramount over the whole of the kingdom--there continued to be endless contests among the feudal barons, and therefore that property alone continued to be valuable which could be secured within the walls of the castle, or driven beyond the assailant's reach--an immense stock of provisions was always stored up in the various fortresses, both for the vassals and the cattle; or it was contrived that the latter should be driven to the domains of some friendly baron, or concealed in some inland recess. when the government became more powerful and settled, and property of every kind was assured a proportionate degree of protection, as well as more equally divided, the plough came into use; agricultural productions were oftener cultivated, the reaping of which was sure after the labor of sowing. cattle were then comparatively neglected and for some centuries injuriously so. their numbers diminished, and their size also seems to have diminished; and it is only within the last century and a half that any serious and successful efforts have been made materially to improve them. in the comparatively roving and uncertain life which the earlier inhabitants led, their cattle would sometimes stray and be lost. the country was at that time overgrown with forests, and the beasts betook themselves to the recesses of these woods, and became wild and sometimes ferocious. they, by degrees, grew so numerous as to be dangerous to the inhabitants of the neighboring districts. one of the chronicles asserts that many of them harbored in the forests in the neighborhood of london. strange stories are told of some of them, and, doubtless, when irritated, they were fierce and dangerous enough. as, however, civilization advanced, and the forests became thinned and contracted, these animals were seen more rarely, and at length almost disappeared. a few of them, however, are still to be found in the parks of some of the leading english noblemen, who keep them for ornament and as curiosities. the color of this wild breed is invariably white, the muzzle being black; the whole of the inside of the ear, and about one-third of the outside, from the tips downward, red; horns white, with black tips, very fine, and bent upward; some of the bulls have a thin, upright mane, about an inch and a half or two inches long. the beef is finely marbled and of excellent flavor. at the first appearance of any person they set off in full gallop, and at the distance of about two hundred yards, make a wheel around and come boldly up again in a menacing manner; on a sudden they make a full stop at the distance of forty or fifty yards, looking wildly at the object of their surprise; but upon the least motion they all again turn round and fly off with equal speed, but not to the same distance, forming a shorter circle; and, again returning with a more threatening aspect than before, they approach probably within thirty yards, when they again make another stand, and then fly off; this they do several times, shortening their distance and advancing nearer and nearer, till they come within such short distance that most persons think it prudent to leave them. when the cows calve, they hide their calves for a week or ten days in some retired situation, and go and suckle them two or three times a day. if any persons come near the calves they clap their heads close to the ground to hide themselves--a proof of their native wildness. the dams allow no one to touch their young without attacking with impetuous ferocity. when one of the herd happens to be wounded, or has grown weak and feeble through age or sickness, the rest set on it and gore it to death. the breeds of cattle which are now found in great britain, are almost as various as the soil of the different districts or the fancies of the breeders. they have, however, been very conveniently classed according to the comparative size of the horns; the _long-horns_, originally from lancashire, and established through most of the midland counties; the _short-horns_, generally cultivated in the northern counties and in lincolnshire, and many of them found in every part of the kingdom where the farmer pays much attention to his dairy, or where a large supply of milk is desired; and the _middle-horns_, a distinct and valuable breed, inhabiting, principally, the north of devon, the east of sussex, herefordshire, and gloucestershire; and of diminished bulk and with somewhat different character, the cattle of the scottish and welsh mountains. the alderney, with its _crumpled horn_, is found on the southern coast; while the polled, or _hornless_, cattle prevail in suffolk, norfolk, and galloway, whence they were first derived. these leading breeds, however, have been intermingled in every possible way. they are found pure only in their native districts, or on the estate of some wealthy and spirited individuals. each county has its own mongrel breed, often difficult to be described, and not always to be traced--neglected enough, yet suited to the soil and the climate; and among small farmers, maintaining their station, in spite of attempts at improvements by the intermixture or the substitution of foreign varieties. much dispute has arisen as to the original breed of british cattle. the battle has been sharply fought between the advocates of the middle and of the long-horns. the short-horns and the polls are out of the lists; the latter, although it has existed in certain districts from time immemorial, being probably an accidental variety. the weight of argument appears at present to rest with the middle horns; the long-horns being evidently of irish extraction. [illustration: the well-fed beasts.] great britain has shared the fate of other nations, and oftener than they been overrun and subjugated by invaders. as the natives retreated they carried with them some portion of their property, consisting, in the remote and early times, principally of cattle. they drove along with them as many as they could, when they retired to the fortresses of north devon and cornwall, or the mountainous region of wales, or when they took refuge in the retirement of east sussex; and there, retaining all their prejudices, manners, and customs, were jealous of the preservation of that which reminded them of their native country before it yielded to a foreign yoke. in this way was preserved the ancient breed of british cattle. difference of climate produced some change, particularly in their bulk. the rich pasturage of sussex fattened the ox into its superior size and weight. the plentiful, but not so luxuriant, herbage of the north of devon produced a smaller and more active animal; while the privations of wales lessened the bulk and thickened the hide of the welsh stock. as for scotland, it set its invaders at defiance; or its inhabitants retreated for a while, and soon turned again on their pursuers. they were proud of their country, and of their cattle, their choicest possession; and there, also, the cattle were preserved, unmixed and undegenerated. thence it has resulted, that in devon, in sussex, in wales, and in scotland, the cattle have been the same from time immemorial; while in all the eastern coasts and through every district of england, the breed of cattle degenerated, or lost its original character; it consisted of animals brought from all the neighboring, and some remote districts, mingled in every possible variety, yet conforming to the soil and the climate. careful observations will establish the fact, that the cattle in devonshire, sussex, wales, and scotland are essentially the same. they are middle horned; not extraordinary milkers, and remarkable for the quality rather than the quantity of their milk; active at work, and with an unequalled aptitude to fatten. they have all the characters of the same breed, changed by soil, climate, and time, yet little changed by man. the color, even, may be almost traced, namely: the red of the devon, the sussex, and the hereford; and where only the black are now found, the recollection of the red prevails. as this volume is intended especially for the farmers of our own country, it is deemed unnecessary in this connection to present any thing additional under the present head, except the names of the prominent species of british cattle. these are, commencing with the middle horns, the north devon, the hereford, the sussex, the welsh (with the varieties of the pembrokeshire, the glamorganshire, the radnor black, the anglesea and some others); and the scotch with its chief varieties, the west highlanders, the north highlanders, the north eastern, the fife, the ayrshire, and the galloways. as to the long horns, which came originally from craven in yorkshire, it may be remarked that this breed has been rapidly disappearing of late, and has everywhere given place to better kinds. of this species there are--or perhaps were--two leading classes, the lancashire and the leicestershire improved. of the short horns, the leading breeds are the dutch, the holderness, the teeswater, the yorkshire, the durham, the northumberland, and some others. american cattle. the breeds of cattle which stock the farms of the united states are all derived from europe, and, with few exceptions, from great britain. the highest breeds at the present time are of comparatively recent origin, since the great improvements in breeding were only commenced at about the period of the american revolution. the old importations made by the early settlers, must consequently have been from comparatively inferior grades. in some sections of the union, and more particularly in new england, the primitive stock is thought to have undergone considerable improvement; whilst in many parts of the middle, and especially of the southern states, a greater or less depreciation has ensued. the prevailing stock in the eastern states is believed to be derived from the north devons, most of the excellent marks and qualities of which they possess. for this reason they are very highly esteemed, and have been frequently called the american devon. the most valuable working oxen are chiefly of this breed, which also contributes so largely to the best displays of beef found in the markets of boston, new york, and philadelphia. by means of this domestic stock, and the importations still extensively made of selections from the short horns, and others of the finest european breeds, the cattle, not only of new england, but of other sections, are rapidly improving, especially in the middle and western states. a brief sketch of the principal breeds of american cattle, as well as of the grades or common stock of the country, will be of service to the farmer in making an intelligent selection with reference to the special object of pursuit--whether it be the dairy, the production of beef, or the raising of cattle for work. in selecting any breed, regard should be had to the circumstances of the individual farmer and the object to be pursued. the cow most profitable for the milk dairy, may be very unprofitable in the butter and cheese dairy, as well as for the production of beef; while, for either of the latter objects, the cow which gave the largest quantity of milk might be very undesirable. a union and harmony of all good qualities must be secured, so far as possible. the farmer wants a cow that will milk well for some years; and then, when dry, fatten readily and sell to the butcher for the highest price. these qualities, often supposed to be utterly incompatible, will be found united in some breeds to a greater extent than in others; while some peculiarities of form have been found, by observation, to be better adapted to the production of milk and beef than others. it is proposed, therefore, to sketch the pure breeds now found in america. the ayrshire. [illustration: an ayrshire bull.] this breed is justly celebrated throughout great britain and this country for its excellent dairy qualities. though the most recent in their origin, they are pretty distinct from the scotch and english races. in color, the pure ayrshires are generally red and white, spotted or mottled, not roan like many of the short horns, but often presenting a bright contrast of colors. they are sometimes, though rarely, nearly or quite all red, and sometimes black and white; but the favorite color is red and white brightly contrasted; and, by some, strawberry-color is preferred. the head is small, fine and clean; the face long and narrow at the muzzle, with a sprightly, yet generally mild expression; eye small, smart and lively; the horns short, fine, and slightly twisted upward, set wide apart at the roots; the neck thin; body enlarging from fore to hind quarters; the back straight and narrow, but broad across the loin; joints rather loose and open; ribs rather flat; hind quarters rather thin; bone fine; tail long, fine, and bushy at the end; hair generally thin and soft; udder light color and capacious, extending well forward under the belly; teats of the cow of medium size, generally set regularly and wide apart; milk-veins prominent and well developed. the carcass of the pure bred ayrshire is light, particularly the fore quarters, which is considered by good judges as an index of great milking qualities; but the pelvis is capacious and wide over the hips. on the whole, the ayrshire is good looking, but wants some of the symmetry and aptitude to fatten which characterize the short horn, which is supposed to have contributed to build up this valuable breed on the basis of the original stock of the county of ayr, which extends along the eastern shore of the firth of clyde, in the southwestern part of scotland. the original stock of this country are described as of a diminutive size, ill fed, ill shaped, and yielding but a scanty return in milk. they were mostly of a black color, with large stripes of white along the chine and ridge of their backs, about the flanks, and on their faces. their horns were high and crooked, having deep ringlets at the root--the surest proof that they were but scantily fed; the chine of their backs stood up high and narrow; their sides were lank, short, and thin; their hides thick and adhering to the bones; their pile was coarse and open; and few of them gave more than six or eight quarts of milk a day when in their best condition, or weighed, when fat, more than from a hundred to a hundred and sixty pounds avoirdupois, rejecting offal. a wonderful change has since been made in the condition, aspect, and qualities of the ayrshire dairy stock. they are now almost double the size, and yield about four times the quantity of milk that the ayrshire cows formerly yielded. a large part of this improvement is due to better feeding and care, but much, no doubt, to judicious crossing. strange as it may seem, considering the modern origin of this breed, all that is certainly known touching it is, that about a century and a half ago there was no such breed as ayrshire in scotland. the question has therefore arisen, whether these cattle came entirely from a careful selection of the best native breed. if they did, it is a circumstance without a parallel in the history of agriculture. the native breed may indeed be ameliorated by careful selection; its value may be incalculably increased; some good qualities, some of its best qualities, may be developed for the first time; but yet there will be some resemblance to the original stock, and the more the animal is examined, the more clearly can be traced the characteristic points of the ancestor, although every one of them is improved. youatt estimates the daily yield of an ayrshire cow, for the first two or three months after calving, at five gallons a day, on an average; for the next three months, at three gallons; and for the next four months, at one gallon and a half. this would give eight hundred and fifty gallons as the annual average; but, allowing for some unproductive cows, he estimates the average of a dairy at six hundred gallons a year for each cow. three gallons and a half of the ayrshire cow's milk will yield one and a half pounds of butter. some have estimated the yield still higher. one of the four cows originally imported into this country by john p. cushing, esq., of massachusetts, gave in one year three thousand eight hundred and sixty-four quarts, beer measure, or about nine hundred and sixty-six gallons, at ten pounds the gallon; being an average of over ten and a half beer quarts a day for the entire year. the first cow of this breed, imported by the massachusetts society, for the promotion of agriculture, in 1837, yielded sixteen pounds of butter a week for several successive weeks, on grass feed only. it should be borne in mind, in this connection that the climate of new england is less favorable to the production of milk than that of england and scotland, and that no cow imported after arriving at maturity can be expected to yield as much, under the same circumstances, as one bred on the spot where the trial is made, and perfectly acclimated. on excellent authority, the most approved shape and marks of a good dairy cow are as follows: head small, long, and narrow toward the muzzle; horns small, clear, bent, and placed at considerable distance from each other; eyes not large, but brisk and lively; neck slender and long, tapering toward the head, with a little loose skin below; shoulders and fore quarters light and thin; hind quarters large and broad; back straight, and joints slack and open; carcass deep in the rib; tail small and long, reaching to the heels; legs small and short, with firm joints; udder square, but a little oblong, stretching forward, thin skinned and capacious, but not low hung; teats or paps small, pointing outward, and at a considerable distance from each other; milk-veins capacious and prominent; skin loose, thin, and soft like a glove; hair short, soft, and woolly; general figure, when in flesh, handsome and well proportioned. if this description of the ayrshire cow be correct, it will be seen that her head and neck are remarkably clean and fine, the latter swelling gradually toward the shoulders, both parts being unencumbered with superfluous flesh. the same general form extends backward, the fore quarters being, light the shoulders thin, and the carcass swelling out toward the hind quarters, so that when standing in front of her it has the form of a blunted wedge. such a structure indicates very fully developed digestive organs, which exert a powerful influence on all the functions of the body, and especially on the secretion of the milky glands, accompanied with milk-veins and udder partaking of the same character as the stomach and viscera, being large and capacious, while the external skin and interior walls of the milk-glands are thin and elastic, and all parts arranged in a manner especially adapted for the production of milk. a cow with these marks will generally be of a quiet and docile temper, which greatly increases her value. a cow that is of a quiet and contented disposition feeds at ease, is milked with ease, and yields more than one of an opposite temperament; while, after she is past her usefulness as a milker, she will easily take on fat, and make fine beef and a good quantity of tallow, because she feeds freely, and when dry the food which went to make milk is converted into fat and flesh. but there is no breed of cows with which gentle gentleness of treatment is so indispensable as with the ayrshire, on account of her naturally nervous temperament. if she receives other than kind and gentle treatment, she will often resent it with angry looks and gestures, and withhold her milk; and if such treatment is long continued, will dry up; but she willingly and easily yields it to the hand that fondles her, and all her looks and movements toward her friends are quiet and mild. the ayrshires in their native country are generally bred for the dairy, and for no other object; and the cows have justly obtained a world-wide reputation for this quality. the oxen are, however, very fair as working cattle, though they cannot be said to excel other breeds in this respect. the ayrshire steer maybe fed and turned at three years old; but for feeding purposes the ayrshires are greatly improved by a cross with the short horns, provided regard is had to the size of the animal. it is the opinion of good breeders that a high-bred short horn bull and a large-sized ayrshire cow will produce a calf which will come to maturity earlier, and attain greater weight, and sell for more money than a pure-bred ayrshire. this cross, with feeding from the start, may be sold fat at two or three years old, the improvement being most noticeable in the earlier maturity and size. in the cross with the short horn, the form ordinarily becomes more symmetrical, while there is, perhaps, little risk of lessening the milking qualities of the offspring, if sufficient regard is paid to the selection of the individual animals to breed from. it is thought by some that in the breeding of animals it is the male which gives the external form, or the bony and muscular system of the young, while the female imparts the respiratory organs, the circulation of the blood, the organs of secretion, and the like. if this principle be true, it follows that the milking qualities come chiefly from the mother, and that the bull cannot materially alter the conditions which determine the transmission of these qualities, especially when they are as strongly marked as they are in this breed. until, however, certain mooted questions connected with breeding are definitively settled, it is the safest plan, in breeding for the dairy, to adhere to the rule of selecting only animals whose progenitors on both sides have been distinguished for their milking qualities. it may be stated, in conclusion, that for purely dairy purposes the ayrshire cow deserves the first place. in consequence of her small, symmetrical, and compact body, combined with a well-formed chest and a capacious stomach, there is little waste, comparatively speaking, through the respiratory system; while at the same time there is very complete assimilation of the food, and thus she converts a very large proportion of her food into milk. so remarkable is this fact, that all dairy farmers who have any experience on the point, agree in stating that _an ayrshire cow generally gives a larger return of milk for the food consumed than a cow of any other breed_. the absolute quality may not be so great, but it is obtained at a less cost; and this is the point upon which the question of profit depends. the best milkers which have been known in this country were grade ayrshires, larger in size than the pure bloods, but still sufficiently high grades to give certain signs of their origin. this grade would seem to possess the advantage of combining, to some extent, the two qualities of milking and adaptation to beef; and this is no small recommendation of the stock to farmers situated as american farmers are, who wish for milk for some years and then to turn over to the butcher. the jersey. these cattle are now widely known in this country. many of them have been imported from an island of the same name in the british channel, near the coast of france, and they may now be considered, for all practical purposes, as fully acclimated. they were first introduced, upward of thirty years ago, from the channel islands, alderney, guernsey, and jersey. this race is supposed to have been originally derived from normandy, in the northern part of france. the cows have been long celebrated for the production of very rich milk and cream, but till within the last twenty-five or thirty years they were comparatively coarse, ugly, and ill-shaped. improvements have been very marked, but the form of the animal is still far from satisfying the eye. the head of the pure jersey is fine and tapering, the cheek small, the throat clean, the muzzle fine and encircled with a light stripe, the nostril high and open; the horns smooth, crumpled, but not very thick at the base, tapering and tipped with black; ears small and thin, deep orange color inside; eyes full and placid; neck straight and fine; chest broad and deep; barrel hoofed, broad and deep, well ribbed up; back straight from the withers to the hip, and from the top of the hip to the setting of the tail; tail fine, at right angles with the back, and hanging down to the hocks; skin thin, light color, and mellow, covered with fine soft hair; fore legs short, straight and fine below the knee, arm swelling and full above; hind quarters long and well filled; hind legs short and straight below the hocks, with bones rather fine, squarely placed, and not too close together; hoofs small; udder full in size, in line with the belly, extending well up behind; teats of medium size, squarely placed and wide apart, and milk-veins very prominent. the color is generally cream, dun, or yellow, with more or less of white, and the fine head and neck give the cows and heifers a fawn-like appearance, and make them objects of attraction in the park; but the hind quarters are often too narrow to work well, particularly to those who judge animals by the amount of fat which they carry. it should be borne in mind, however, that a good race of animals is not always the most beautiful, as that term is generally understood. beauty in stock has no invariable standard. in the estimation of some, it results mainly from fine forms, small bones, and close, compact frames; while others consider that structure the most perfect, and therefore the most beautiful, which is best adapted to the use for which it is destined. with such, beauty is relative. it is not the same in an animal designed for beef and in one designed for the dairy or for work. the beauty of a milch cow is the result of her good qualities. large milkers are very rarely cows that please the eye of any but a skillful judge. they are generally poor, since their food goes mainly to the production of milk, and because they are selected with less regard to form than to good milking qualities. the prevailing opinion as to the beauty of the jersey, is based on the general appearance of the cow when in milk--no experiments in feeding exclusively for beef having been made public, and no opportunity to form a correct judgment from actual observation having been furnished; and it must be confessed that the general appearance of the breed would amply justify the hasty conclusion. the bulls are usually very different in character and disposition from the cows, and are much inclined to become restive and cross at the age of two or three years, unless their treatment is uniformly gentle and firm. the jersey is to be regarded as a dairy breed, and that almost exclusively. it would not be sought for large dairies kept for the supply of milk to cities; for, though the quality would gratify the customer, the quantity would not satisfy the owner. the place of the jersey cow is rather in private establishments, where the supply of cream and butter is a sufficient object; or, in limited numbers, to add richness to the milk of large butter dairies. even one or two good jersey cows with a herd of fifteen or twenty, will make a great difference in the quality of the milk and butter of the whole establishment; and they would probably be profitable for this, if for no other object. the short horns. no breed of cattle has commanded more universal admiration during the last half century than the improved short horns, whose origin can be traced back for nearly a hundred years. according to the best authorities, the stock which formed the basis of improvement existed equally in yorkshire, lincolnshire, northumberland, and the adjoining counties; and the pre-eminence was accorded to durham, which gave its name to the race, from the more correct principles of breeding which seem to have obtained there. there is a dispute among the most eminent breeders as to how far it owes its origin to early importations from holland, whence many superior animals were brought for the purpose of improving the old long horned breed. a large race of cattle had existed for many years on the western shores of the continent of europe. as early as 1633, they were imported from denmark into new england in considerable numbers, and thus laid the foundation of a valuable stock in farming at a very early date in holland, and experience led to the greatest care in the choice and breeding of dairy stock. from these cattle many selections were made to cross over to the counties of york and durham. the prevailing color of the large dutch cattle was black and white, beautifully contrasted. [illustration: a short horn bull.] the cattle produced by these crosses a century ago were known by the name of "dutch." the cows selected for crossing with the early imported dutch bulls were generally long horned, large boned, coarse animals, a fair type of which was found in the old "holderness" breed of yorkshire--slow feeders, strong in the shoulder, defective in the fore quarter, and not very profitable to the butcher, their meat being coarse and uninviting. their milking qualities were good, surpassing those, probably, of the improved short horns. whatever may be the truth with regard to these crosses, and however far they proved effective in creating or laying the foundation of the modern improved short horns, the results of the efforts made in yorkshire and some of the adjoining counties were never so satisfactory to the best judges as those of the breeders along the tees, who selected animals with greater reference to fineness of bone and symmetry of form, and the animals they bred soon took the lead and excited great emulation in improvement. importations of short horns have been frequent and extensive into the united states within the last few years, and this famous breed is now pretty generally diffused over the country. the high-bred short horn is easily prepared for a show, and, as fat will cover faults, the temptation is often too great to be resisted; and hence it is not uncommon to see the finest animals rendered unfit for breeding purposes by over-feeding. the race is susceptible of breeding for the production of milk, as several families show, and great milkers have often been known among pure-bred animals; but it is more common to find it bred mainly for the butcher, and kept accordingly. it is, however, a well-known fact, that the dairies of london are stocked chiefly with short horns and yorkshires, or high grades between them, which, after being milked as long as profitable, feed equal, or nearly so, to pure-bred short horns. it has been said, by very good authority, that the short horns improve every breed with which they cross. the desirable characteristics of the short horn bull may be summed up, according to the judgment of the best breeders, as follows: he should have a short but fine head, very broad across the eyes, tapering to the nose, with a nostril full and prominent; the nose itself should be of a rich flesh color; eyes bright and mild; ears somewhat large and thin; horns slightly covered and rather flat, well set on; a long, broad, muscular neck; chest wide, deep, and projecting; shoulders fine, oblique, well formed into the chine; fore legs short, with upper arm large and powerful; barrel round, deep, well-ribbed horns; hips wide and level; back straight from the withers to the setting on of the tail, but short from hips to chine; skin soft and velvety to the touch; moderately thick hair, plentiful, soft, and mossy. the cow has the same points in the main, but her head is finer, longer, and more tapering; neck thinner and lighter, and shoulders more narrow across the chine. the astonishing precocity of the short horns, their remarkable aptitude to fatten, the perfection of their forms, and the fineness of their bony structure, give them an advantage over most other races when the object of breeding is for the shambles. no animal of any other breed can so rapidly transform the stock of any section around him as the improved short horn bull. it does not, however, follow that the high-bred short horns are unexceptionable, even for beef. the very exaggeration, so to speak, of the qualities which make them so valuable for the improvement of other and less perfect races, may become a fault when wanted for the table. the very rapidity with which they increase in size is thought by some to prevent their meat from ripening up sufficiently before being hurried off to the butcher. the disproportion of the fatty to the muscular flesh, found in this to a greater extent than in races coming more slowly to maturity, makes the meat of the thorough-bred short horn, in the estimation of some, less agreeable to the taste, and less profitable to the consumer; since the nitrogenous compounds, true sources of nutriment, are found in less quantity than in the meat of animals not so highly bred. in sections where the climate is moist, and the food abundant and rich, some families of the short horns may be valuable for the dairy; but they are most frequently bred exclusively for beef in this country, and in sections where they have attained the highest perfection of form and beauty, so little is thought of their milking qualities that they are often not milked at all, the calf being allowed to run with the dam. the dutch. this short horned race, in the opinion of many--as has been previously remarked--contributed largely, about a century ago, to build up the durham or teeswater stock. it has been bred with special reference to dairy qualities, and is eminently adapted to supply the wants of the dairy farmer. the cows of north holland not only give a large quantity, but also a very good quality, so that a yield of sixteen to twenty-five quarts, wine measure, at every milking, is not rare. the principles upon which the inhabitants of holland practise, in selecting a cow from which to breed, are as follows: she should have, they say, considerable size--not less than four and a half or five feet girth, with a length of body corresponding; legs proportionally short; a finely formed head, with a forehead or face somewhat concave; clear, large, mild and sparkling eyes, yet with no expression of wildness; tolerably large and stout ears, standing out from the head; fine, well curved horns; a rather short, than long, thick, broad neck, well set against the chest and withers; the front part of the breast and shoulders must be broad and fleshy; the low-hanging dewlap must be soft to the touch; the back and loins must be properly projected, somewhat broad, the bones not too sharp, but well covered with flesh; the animal should have long curved ribs, which form a broad breast bone; the body must be round and deep, but not sunken into a hanging belly; the rump must not be uneven, the hip-bones should not stand out too broad and spreading, but all the parts should be level and well filled up; a fine tail, set moderately high up and tolerably long, but slender, with a thick, bushy tuft of hair at the end, hanging down below the hocks; the legs must be short and low, but strong in the bony structure; the knees broad, with flexible joints; the muscles and sinews must be firm and sound, the hoofs broad and flat, and the position of the legs natural, not too close and crowded; the hide, covered with fine glossy hair, must be soft and mellow to the touch, and set loose upon the body. a large, rather long, white and loose udder, extending well back, with four long teats, serves also as a characteristic mark of a good milch cow. large and prominent milk-veins must extend from the navel back to the udder; the belly of a good milch cow should not be too deep and hanging. the color of the north dutch cattle is mostly variegated. cows with only one color are no favorites. red or black variegated, gray and blue variegated, roan, spotted and white variegated cows, are especially liked. the hereford. these cattle derive their name from a county in the western part of england. their general characteristics are a white face, sometimes mottled; white throat, the white generally extending back on the neck, and sometimes, though rarely, still further along on the back. the color of the rest of the body is red, generally dark, but sometimes light. eighty years ago the best hereford cattle were mottled or roan all over; and some of the best herds, down to a comparatively recent period, were either all mottled, or had the mottled or speckled face. the expression of the face is mild and lively; the forehead open, broad, and large; the eyes bright and full of vivacity; the horns glossy, slender and spreading; the head small, though larger than, and not quite so clear as, that of the devons; the lower jaw fine; neck long and slender; chest deep; breast-bone large, prominent, and very muscular; the shoulder-blade light; shoulder full and soft; brisket and loins large; hips well developed, and on a level with the chine; hind quarters long and well filled in; buttocks on a level with the back, neither falling off nor raised above the hind quarters; tail slender, well set on; hair fine and soft; body round and full; carcass deep and well formed, or cylindrical; bone small; thigh short and well made; legs short and straight, and slender below the knee; as handlers very excellent, especially mellow to the touch on the back, the shoulder, and along the sides, the skin being soft, flexible, of medium thickness, rolling on the neck and the hips; hair bright; face almost bare, which is characteristic of pure herefords. they belong to the middle horned division of the cattle of great britain, to which they are indigenous, and have been improved within the last century by careful selections. hereford oxen are excellent animals, less active but stronger than the devons, and very free and docile. the demand for herefords for beef prevents their being much used for work in their native county, and the farmers there generally use horses instead of oxen. it is generally conceded that the qualities in which herefords stand pre-eminent among the middle-sized breeds are in the production of oxen and their superiority of flesh. on these points there is little chance of their being excelled. it should, however, be borne in mind that the best oxen are not produced from the largest cows; nor is a superior quality of flesh, such as is considered very soft to the touch, with thin skin. it is the union of these two qualities which often characterizes the short horns; but hereford breeders--as a recent writer remarks--should endeavor to maintain a higher standard of excellence--that for which the best of the breed have always been esteemed--a moderately thick, mellow hide, with a well apportioned combination of softness with elasticity. a sufficiency of hair is also desirable, and if accompanied with a disposition to curl moderately, it is more in esteem; but that which has a harsh and wiry feel is objectionable. in point of symmetry and beauty of form, the well bred herefords may be classed with the improved short horns, though they arrive somewhat more slowly at maturity, and never attain such weight. like the improved short horns, they are chiefly bred for beef, and their beef is of the best quality in the english markets, commanding the highest price of any, except perhaps, the west highlanders. the short horn produces more beef at the same age than the hereford, but consumes more food in proportion. the herefords are far less generally spread over england than the improved short horns. they have seldom been bred for milk, as some families of the latter have; and it is not very unusual to find pure-bred cows incapable of supplying milk sufficient to nourish their calves. they have been imported to this country to some extent, and several fine herds exist in different sections; the earliest importations being those of henry clay, of kentucky, in 1817. the want of care and attention to the udder, soon after calving, especially if the cow be on luxuriant grass, often injures her milking properties exceedingly. the practice in the county of hereford has generally been to let the calves suckle from four to six months, and bull calves often run eight months with the cow. but their dairy qualities are perhaps as good as those of any cattle whose fattening properties have been so carefully developed; and, though it is probable that they could be bred for milk with proper care and attention, yet, as this change would be at the expense of other qualities equally valuable, it would evidently be wiser to resort to other stock for the dairy. the north devons. [illustration: a north devon steer.] this beautiful race of middle horned cattle dates further back than any well established breed among us. it goes generally under the simple name of devon; but the cattle of the southern part of the country, from which the race derives its name, differ somewhat from those of the northern, having a larger and coarser frame, and far less tendency to fatten though their dairy qualities are superior. the north devons are remarkable for hardihood, symmetry and beauty, and are generally bred for work and for beef, rather than for the dairy. the head is fine and well set on; the horns of medium length, generally curved; color usually bright blood-red, but sometimes inclining to yellow; skin thin and orange-yellow; hair of medium length, soft and silky, making the animals remarkable as handlers; muzzle of the nose white; eyes full and mild; ears yellowish, or orange-color inside, of moderate size; neck rather long, with little dewlap; shoulders oblique; legs small and straight, with feet in proportion; chest of good width; ribs round and expanded; loins of first-rate quality, long, wide, and fleshy; hips round, of medium width; rump level; tail full near the setting on, tapering to the tip; thighs of the bull and ox muscular and full, and high in the flank, though in the cow sometimes thought to be light; the size medium, generally called small. the proportion of meat on the valuable parts is greater, and the offal less, than on most other breeds, while it is well settled that they consume less food in its production. the devons are popular with the smithfield butchers, and their beef is well marbled or grained. as working oxen, the devons perhaps excel all other races in quickness, docility, beauty, and the ease with which they are matched. with a reasonable load, they are said to be equal to horses as walkers on the road, and when they are no longer wanted for work they fatten easily and turn well. as milkers, they do not excel--perhaps they may be said not to equal--the other breeds, and they have a reputation of being decidedly below the average. in their native country the general average of the dairy is one pound of butter a day during the summer. they are bred for beef and for work, and not for the dairy; and their yield of milk is small, though of a rich quality. several animals, however, of the celebrated patterson herd would have been remarkable as milkers even among good milking stock. still, the faults of the north devon cow, considered as a dairy animal, are too marked to be overlooked. the rotundity of form and compactness of frame, though they contribute to her remarkable beauty constitute an objection to her for this purpose: since it is generally admitted that the peculiarity of form which disposes an animal to take on fat is somewhat incompatible with good milking qualities. on this account, youatt--who is standard authority in such matters--says that for the dairy the north devon must be acknowledged to be inferior to several other breeds. the milk is good, and yields more than the average proportion of cream and butter; but it is deficient in quantity. he also maintains that its property as a milker could not be improved without producing a certain detriment to its grazing qualities. distinguished devon breeders themselves have come to the same conclusion upon this point. the improved north devon cow may be classed, in this respect, with the hereford, neither of which has well developed milk-vessels--a point of the utmost consequence to the practical dairyman. native cattle. the foregoing comprise the pure-bred races in america; for, though other and well-established breeds--like the galloways, the long horns, the spanish, and others--have, at times, been imported, and have had some influence on our american stock, yet they have not been kept distinct to such an extent as to become the prevailing stock of any particular section. a large proportion, however--by far the largest proportion, indeed--of the cattle known among us cannot be included under any of the races to which allusion has been made; and to the consideration of this class the present article is devoted. the term "breed"--as was set forth in the author's treatise, "the horse and his diseases"--when properly understood, applies only to animals of the same species, possessing, besides the general characteristics of that species, other characteristics peculiar to themselves, which they owe to the influence of soil, climate, nourishment, and the habits of life to which they are subjected, and which they transmit with certainty to their progeny. the characteristics of certain breeds or families are so well marked, that, if an individual supposed to belong to any one of them were to produce an offspring not possessing them, or possessing them only in part, with others not belonging to the breed, it would be just ground for suspecting a want of purity of bloods. in this view, no grade animals, and no animals destitute of fixed peculiarities or characteristics which they, share in common with all other animals of the class of which they are a type, and which they are capable of transmitting with certainty to their descendants, can be recognized by breeders as belonging to any one distinct race, breed, or family. the term "native" is applied to a vast majority of our american cattle, which, though born on the soil, and thus in one sense natives, do not constitute a breed, race, or family, as correctly understood by breeders. they do not possess characteristics peculiar to them all, which they transmit with any certainty to their offspring, either of form, size, color, milking or working properties. but, though an animal may be made up of a mixture of blood almost to impurity, it does not follow that, for specific purposes, it may not, as an individual animal, be one of the best of the species. indeed, for particular purposes, animals might be selected from among those commonly called "natives" in new england, and "scrubs" at the west and south, equal, and perhaps superior, to any among the races produced by the most skillful breeding. there can be no objection, therefore, to the use of the term "native," when it is understood as descriptive of no known breed, but only as applied to the common stock of a country, which does not constitute a breed. but perhaps the entire class of animals commonly called "natives" would be more accurately described as grades; since they are well known to have sprung from a great variety of cattle procured at different times and in different places on the continent of europe, in england, and in the spanish west indies, brought together without any regard to fixed principles of breeding, but only from individual convenience, and by accident. the first importations to this country were doubtless those taken to virginia previous to 1609, though the exact date of their arrival is not known. several cows were carried there from the west indies in 1610, and in the next year no less than one hundred arrived there from abroad. [illustration: draft oxen.] the earliest cattle imported into new england arrived in 1624. at the division of cattle which took place three years after, one or two are distinctly described as black, or black and white, others as brindle, showing that there was no uniformity of color. soon after this, a large number of cattle were brought over from england for the settlers at salem. these importations formed the original stock of massachusetts. in 1725, the first importation was made into new york from holland by the dutch west india company, and the foundation was then laid for an exceedingly valuable race of animals, which, subsequent importations from the same country, as well as from england, have greatly improved. the points and value of this race in its purity have been already adverted to under the head of the dutch cattle. in 1627, cattle were brought from sweden to the settlements on the delaware, by the swedish west india company. in 1631, 1632, and 1633, several importations were made into new hampshire by captain john mason who, with gorges, had procured the patent of large tracts of land in the vicinity of the piscataqua river, and who immediately formed settlements there. the object of mason was to carry on the manufacture of potash. for this purpose he employed the danes; and it was in his voyage to and from denmark that he procured many danish cattle and horses, which were subsequently scattered over that entire region, large numbers being driven to the vicinity of boston and sold. these danish cattle are described as large and coarse, of a yellow color; and it is supposed that they were procured by mason as being best capable of enduring the severity of the climate and the hardships to which they would be subjected. however this may have been, they very soon spread among the colonists of the massachusetts bay, and have undoubtedly left their marks on the stock of the new england and the middle states, which exist to some extent even to the present day, mixed in with an infinite multitude of crosses with the devons, the dutch cattle already alluded to, the black cattle of spain and wales, and the long horn and the short horn--most of which crosses were accidental, or due to local circumstances or individual convenience. many of these cattle, the descendants of such crosses, are of a very high order of merit; but to which particular cross this is due, it is impossible to say. they generally make hardy, strong, and docile oxen, easily broken to the yoke and quick to work, with a fair tendency to fatten when well fed; while the cows, though often ill-shaped, are sometimes remarkably good milkers, especially as regards the quantity which they give. indeed, it has been remarked by excellent judges of stock, that if they desired to select a dairy of cows for milk for sale, they would make their selection from cows commonly called native, in preference to pure-bred animals of any of the established breeds, and that they believed they should find such a dairy the most profitable. in color, the natives, made up as already indicated, are exceedingly various. the old denmarks, which to a considerable extent laid the foundation of the stock of maine and new hampshire, were light yellow. the dutch of new york and the middle states, were black and white; the spanish and welsh were generally black; the devons, which are supposed to have laid the foundation of the stock of some of the states, were red. crosses of the denmark with the spanish and welsh naturally made a dark brindle; crosses of the devon often made a lighter or yellowish brindle while the more recent importations of jerseys and short horns have generally produced a beautiful spotted progeny. the deep red has long been a favorite color in new england; but the prejudice in its favor is fast giving way to more variegated colors. among the earlier importations into this country were also several varieties of hornless cattle, which have been kept measurably distinct in some sections; or where they have been crossed with the common stock there has been a tendency to produce hornless grades. these are not unfrequently known as "buffalo cattle." they were, in many cases, supposed to belong to the galloway breed; or, which is more likely, to the suffolk dun, a variety of the galloway, and a far better milking stock than the galloways, from which, it sprung. these polled, or hornless cattle vary in color and qualities, but they are usually very good milkers when well kept, and many of them fatten well, and attain good weight. the hungarian cattle have also been imported, to some extent, into different parts of the country, and have been crossed upon the natives with some success. many other strains of blood from different breeds have also contributed to build up the common stock of the country of the present day; and there can be no question that its appearance and value have been largely improved during the last quarter of a century, nor that improvements are still in progress which will lead to satisfactory results in the future. but, though we already have an exceedingly valuable foundation for improvement, no one will pretend to deny that our cattle, as a whole, are susceptible of it in many respects. they possess neither the size, the symmetry, nor the early maturity of the short horns; they do not, as a general thing, possess the fineness of bone, the beauty of form and color, nor the activity of the devons or the herefords; they do not possess that uniform richness of milk, united with generous quality, of the ayrshires, nor the surpassing richness of milk of the jerseys: but, above all, they do not possess the power of transmitting the many good qualities which they often have to their offspring--which is the characteristic of all well established breeds. it is equally certain, in the opinion of many good judges, that the dairy stock of the country has not been materially improved in its intrinsic good qualities during the last thirty or forty years. this may not be true of certain sections, where the dairy has been made a special object of pursuit, and where the custom of raising the best male calves of the neighborhood, or those that came from the best dairy cows, and then of using only the best formed bulls, has long prevailed. although in this way some progress has, doubtless, been made, there are still room and need for more. more attention must be paid to correct principles of breeding before the satisfactory results which every farmer should strive to reach can be attained. having glanced generally at the leading breeds of cattle in great britain, and examined, more in detail, the various breeds in the united states, the next subject demanding attention is, the natural history of cattle.

[illustration: teeth at birth.] the rings on the horns of a bull are either not seen until five, or they cannot be traced at all; while in the ox they do not appear till he is five years old, and then are often very indistinct. in addition to this, it is by no means an uncommon practice to file the horns, so as to make them smooth, and to give the animal the appearance of being much younger than it really is. this is, therefore, an exceedingly fallacious guide, and cannot be relied upon by any one with the degree of confidence desired. [illustration: second week.] the surest indication of the age in cattle, as in the horse, is given by the teeth. the calf, at birth, will usually have two incisor or front teeth--in some cases just appearing through the gums; in others, fully set, varying as the cow falls short of, or exceeds, her regular time of calving. if she overruns several days, the teeth will have set and attained considerable size, as appears in the cut representing teeth at birth. during the second week, a tooth will usually be added on each side, and the mouth will generally appear as in the next cut; and before the end of the third week, the animal will generally have six incisor teeth, as denoted in the cut representing teeth at the third week; and in a week from that time the full number of incisors will have appeared, as seen in the next cut. [illustration: three weeks.] [illustration: month.] [illustration: five to eight months.] [illustration: ten months.] [illustration: twelve months.] [illustration: fifteen months.] these teeth are temporary, and are often called milk-teeth. their edge is very sharp; and as the animal begins to live upon more solid food, this edge becomes worn, showing the bony part of the tooth beneath, and indicates with considerable precision the length of time they have been used. the centre, or oldest teeth show the marks of age first, and often become somewhat worn before the corner teeth appear. at eight weeks, the four inner teeth are nearly as sharp as before. they appear worn not so much on the outer edge or line of the tooth, as inside this line; but, after this, the edge begins gradually to lose its sharpness, and to present a more flattened surface; while the next outer teeth wear down like the four central ones; and at three months this wearing off is very apparent, till at four months all the incisor teeth appear worn, but the inner ones the most. now the teeth begin slowly to diminish in size by a kind of contraction, as well as wearing down, and the distance apart becomes more and more apparent. [illustration: eighteen months.] from the fifth to the eighth month, the inner teeth will usually appear as in the cut of the teeth at that time; and at ten months, this change shows more clearly, as represented in the next cut; and the spaces between them begin to show very plainly, till at a year old they ordinarily present the appearance of the following cut; and at the age of fifteen months, that shown in the next, where the corner teeth are not more than half the original size, and the centre ones still smaller. [illustration: two years past.] the permanent teeth are now rapidly growing, and preparing to take the place of the milk-teeth, which are gradually absorbed till they disappear, or are pushed out to give place to the two permanent central incisors, which at a year and a half will generally present the appearance indicated in the cut, which shows the internal structure of the lower jaw at this time, with the cells of the teeth, the two central ones protruding into the mouth, the next two pushing up, but not quite grown to the surface, with the third pair just perceptible. these changes require time; and at two years past the jaw will usually appear as in the cut, where four of the permanent central incisors are seen. after this, the other milk-teeth decrease rapidly, but are slow to disappear; and at three years old, the third pair of permanent teeth are but formed, as represented in the cut; and at four years the last pair of incisors will be up, as in the cut of that age; but the outside ones are not yet fully grown, and the beast can hardly be said to be full-mouthed till the age of five years. but before this age, or at the age of four years, the two inner pairs of permanent teeth are beginning to wear at the edges, as shown in the cut; while at five years old the whole set becomes somewhat worn down at the top, and on the two centre ones a darker line appears in the middle, along a line of harder bone, as appears in the appropriate cut. [illustration: three years past.] [illustration: four years past.] [illustration: five years past.] [illustration: ten years past.] now will come a year or two, and sometimes three, when the teeth do not so clearly indicate the exact age, and the judgment must be guided by the extent to which the dark middle lines are worn. this will depend somewhat upon the exposure and feeding of the animal; but at seven years these lines extend over all the teeth. at eight years, another change begins, which cannot be mistaken. a kind of absorption begins with the two central incisors--slow at first, but perceptible--and these two teeth become smaller than the rest, while the dark lines are worn into one in all but the corner teeth, till, at ten years, four of the central incisors have become smaller in size, with a smaller and fainter mark, as indicated in the proper cut. at eleven, the six inner teeth are smaller than the corner ones; and at twelve, all become smaller than they were, while the dark lines are nearly gone, except in the corner teeth, and the inner edge is worn to the gum. points of a good cow. after satisfaction is afforded touching the age of a cow, she should be examined with reference to her soundness of constitution. a good constitution is indicated by large lungs, which are found in a deep, broad, and prominent chest, broad and well-spread ribs, a respiration somewhat slow and regular, a good appetite, and if in milk a strong inclination to drink, which a large secretion of milk almost invariably stimulates. in such a cow the digestive organs are active and energetic, and they make an abundance of good blood, which in turn stimulates the activity of the nervous system, and furnishes the milky glands with the means of abundant secretion. such a cow, when dry, readily takes on fat. when activity of the milk-glands is found united with close ribs, small and feeble lungs, and a slow appetite, often attended by great thirst, the cow will generally possess only a weak and feeble constitution; and if the milk is plentiful, it will generally be of bad quality, while the animal, if she does not die of diseased lungs, will not readily take on fat, when dry and fed. [illustration: a good milch cow.] in order to have no superfluous flesh, the cow should have a small, clean, and rather long head, tapering toward the muzzle. a cow with a large, coarse head will seldom fatten readily, or give a large quantity of milk. a coarse head increases the proportion of weight of the least valuable parts, while it is a sure indication that the whole bony structure is too heavy. the mouth should be large and broad; the eye bright and sparkling, but of a peculiar placidness of expression, with no indication of wildness, but rather a mild and feminine look. these points will indicate gentleness of disposition. such cows seem to like to be milked, are fond of being caressed, and often return caresses. the horns should be small, short, tapering, yellowish, and glistening. the neck should be small, thin, and tapering toward the head, but thickening when it approaches the shoulder; the dewlaps small. the fore quarters should be rather small when compared with the hind quarters. the form of the barrel will be large, and each rib should project further than the preceding one, up to the loins. she should be well formed across the hips and in the rump. the spine or back-bone should be straight and long, rather loosely hung, or open along the middle part, the result of the distance between the dorsal vertebræ, which sometimes causes a slight depression, or sway back. by some good judges, this mark is regarded as of great importance, especially when the bones of the hind quarters are also rather loosely put together, leaving the rump of great width and the pelvis large, and the organs and milk-vessels lodged in the cavities largely developed. the skin over the rump should be loose and flexible. this point is of great importance; and as, when the cow is in low condition or very poor, it will appear somewhat harder and closer than it otherwise would, some practice and close observation are required to judge well of this mark. the skin, indeed, all over the body, should be soft and mellow to the touch, with soft and glossy hair. the tail, if thick at the setting on, should taper and be fine below. but the udder is of special importance. it should be large in proportion to the size of the animal, and the skin thin, with soft, loose folds extending well back, capable of great distension when filled, but shrinking to a small compass when entirely empty. it must be free from lumps in every part, and provided with four teats set well apart, and of medium size. nor is it less important to observe the milk-veins carefully. the principal ones under the belly should be large and prominent, and extend forward to the navel, losing themselves, apparently, in the very best milkers, in a large cavity in the flesh, into which the end of the finger can be inserted; but when the cow is not in full milk, the milk-vein, at other times very prominent, is not so distinctly traced; and hence, to judge of its size when the cow is dry, or nearly so, this vein may be pressed near its end, or at its entrance into the body, when it will immediately fill up to its full size. this vein does not convey the milk to the udder, as some suppose, but is the channel by which the blood returns; and its contents consist of the refuse of the secretion, or of what has not been taken up in forming milk. there are also veins in the udder, and the perineum, or the space above the udder, and between that and the buttocks, which it is of special importance to observe. these veins should be largely developed, and irregular or knotted, especially those of the udder. they are largest in great milkers. the knotted veins of the perineum, extending from above downwards in a winding line, are not readily seen in young heifers, and are very difficult to find in poor cows, or those of only a medium quality. they are easily found in very good milkers, and if not at first apparent, they are made so by pressing upon them at the base of the perineum, when they swell up and send the blood back toward the vulva. they form a kind of thick network under the skin of the perineum, raising it up somewhat, in some cases near the vulva, in others nearer down and closer to the udder. it is important to look for these veins, as they often form a very important guide, and by some they would be considered as furnishing the surest indications of the milking qualities of the cow. full development almost always shows an abundant secretion of milk; but they are far better developed after the cow has had two or three calves, when two or three years' milking has given full activity to the milky glands, and attracted a large flow of blood. the larger and more prominent these veins the better. it is needless to say that in observing them some regard should be had to the condition of the cow, the thickness of skin and fat by which they may be surrounded, and the general activity and food of the animal. food calculated to stimulate the greatest flow of milk will naturally increase these veins, and give them more than usual prominence. the milk-mirror. the discovery of m. guénon, of bordeaux, in france--a man of remarkable practical sagacity, and a close observer of stock--consisted in the connection between the milking qualities of the cow and certain external marks on the udder, and on the space above it, called the perineum, extending to the buttocks. to these marks he gave the name of milk-mirror, or escutcheon, which consists in certain perceptible spots rising up from the udder in different directions, forms and sizes, on which the hair grows upward, whilst the hair on other parts of the body grows downward. the reduction of these marks into a system, explaining the value of particular forms and sizes of the milk-mirror, belongs exclusively to guénon. [illustration: milk-mirror [a.]] he divided the milk-mirror into eight classes, and each class into eight orders, making in all no less than sixty-four divisions, which he afterward increased by subdivisions, thus rendering the whole system complicated in the extreme, especially as he professed to be able to judge with accuracy, by means of the milk-mirror, not only of the exact quantity a cow would give, but also of the quality of the milk, and of the length of time it would continue. he endeavored to prove too much, and was, as a matter of consequence, frequently at fault himself. despite the strictures which have been passed upon guénon's method of judging of cows, the best breeders and judges of stock concur in the opinion, as the result of their observations, that cows with the most perfectly developed milk-mirrors are, with rare exception, the best milkers of their breed; and that cows with small and slightly developed milk-mirrors are, in the majority of cases, bad milkers. there are, undoubtedly, cows with very small mirrors, which are, nevertheless, very fair in the yield of milk; and among those with middling quality of mirrors, instances of rather more than ordinary milkers often occur, while at the same time it is true that cases now and then are found where the very best marked and developed mirrors are found on very poor milkers. these apparent exceptions, however, are to be explained, in the large majority of cases, by causes outside of those which affect the appearance of the milk-mirror. it is, of course, impossible to estimate with mathematical accuracy either the quantity, quality, or duration of the milk, since it is affected by so many chance circumstances, which cannot always be known or estimated by even the most skillful judges; such, for example, as the food, the treatment, the temperament, accidental diseases, inflammation of the udder, premature calving, the climate and season, the manner in which she has been milked, and a thousand other things which interrupt or influence the flow of milk, without materially changing the size or shape of the milk-mirror. it has, indeed, been very justly observed that we often see cows equally well formed, with precisely the same milk-mirror, and kept in the same circumstances, yet giving neither equal quantities nor similar qualities of milk. nor could it be otherwise; since the action of the organs depends, not merely on their size and form, but, to a great extent, on the general condition of each individual. [illustration: milk-mirror [b.]] [illustration: milk-mirror [c.]] the different forms of milk-mirrors are represented by the shaded parts of cuts, lettered a, b, c, d; but it is necessary to premise that upon the cows themselves they are always partly concealed by the thighs, the udder, and the folds of the skin, which are not shown, and therefore they are not always so uniform in nature as they appear in the cuts. [illustration: milk-mirror [d.]] their size varies as the skin is more or less folded or stretched; while the cuts represent the skin as uniform or free from folds, but not stretched out. it is usually very easy to distinguish the milk-mirrors by the upward direction of the hair which forms them. they are sometimes marked by a line of bristly hair growing in the opposite direction, which surrounds them, forming a sort of outline by the upward and downward growing hair. yet, when the hair is very fine and short, mixed with longer hairs, and the skin much folded, and the udder voluminous and pressed by the thighs, it is necessary, in order to distinguish the part enclosed between the udder and the legs, and examine the full size of the mirrors, to observe them attentively, and to place the legs wide apart, and to smooth out the skin, in order to avoid the folds. the mirrors may also be observed by holding the back of the hand against the perineum, and drawing it from above downward, when the nails rubbing against the up-growing hair, make the parts covered by it very perceptible. as the hair of the milk-mirror has not the same direction as the hair which surrounds it, it may often be distinguished by a difference in the shade reflected by it. it is then sufficient to place it properly to the light in order to see the difference in shade, and to make out the part covered by the upward-growing hair. most frequently, however, the hair of the milk-mirror is thin and fine, and the color of the skin can easily be seen. if the eye alone is trusted, we shall often be deceived. [illustration: milk-mirror [e.]] in some countries cattle-dealers shave the back part of the cow. just after this operation the mirrors can neither be seen nor felt; but this inconvenience ceases in a few days. it may be added that the shaving--designed, as the dealers say, to beautify the cow--is generally intended simply to destroy the milk-mirror, and to deprive buyers of one means of judging of the milking qualities of the cows. it is unnecessary to add that the cows most carefully shaven are those which are badly marked, and that it is prudent to take it for granted that cows so shorn are bad milkers. milk-mirrors vary in position, extent, and the figure which they represent. they may be divided according to their position, into mirrors or escutcheons, properly so called, or into lower and upper tufts, or escutcheons. the latter are very small in comparison with the former, and are situated in close proximity to the vulva, as seen at 1, in cut e. they are very common on cows of bad milking races, but are very rarely seen on the best milch cows. they consist of one or two ovals, or small bands of up-growing hair, and serve to indicate the continuance of the flow of milk. the period is short, in proportion as the tufts are large. they must not be confounded with the escutcheon proper, which is often extended up to the vulva. they are separated from it by bands of hair, more or less large, as in cut marked f. [illustration: milk-mirror [f.]] milk-mirrors are sometimes symmetrical, and sometimes without symmetry. when there is a great difference in the extent of the two halves, it almost always happens that the teats on the side where the mirror is best developed give more milk than those of the opposite side. the left half of the mirror, it may be remarked, is almost always the largest; and so, when the perinean part is folded into a square, it is on this side of the body that it unfolds. of three thousand cows in denmark, but a single one was found, whose escutcheon varied even a little from this rule. the mirrors having a value in proportion to the space which they occupy, it is of great importance to attend to all the rows of down-growing hairs, which diminish the extent of surface, whether these tufts are in the midst of the mirror, or form indentations on its edges. these indentations, concealed in part by the folds of the skin, are sometimes seen with difficulty; but it is important to take them into account, since in a great many cows they materially lessen the size of the mirror. cows are often found, whose milk-mirrors at first sight appear very large, but which are only medium milkers; and it will usually be found that lateral indentations greatly diminish the surface of up-growing hair. many errors are committed in estimating the value of such cows, from a want of attention to the real extent of the mirror. all the interruptions in the surface of the mirror indicate a diminution in the quantity of the milk, with the exception, however, of small oval or elliptical plates which are found in the mirror, on the back part of the udders of the best cows, as represented in the cut already given, marked a. these ovals have a peculiar tint, which is occasioned by the downward direction of the hair which forms them. in the best cows these ovals exist with the lower mirrors very well developed, as represented in the cut just named. in short, it should be stated that, in order to determine the extent and significance of a mirror, it is necessary to consider the state of the perineum as to fat, and that of the fullness of the udder. in a fat cow, with an inflated udder, the mirror would appear larger than it really is; whilst in a lean cow, with a loose and wrinkled udder, it appears smaller. fat will cover faults--a fact to be borne in mind when selecting a cow. in bulls, the mirrors present the same peculiarities as in cows; but they are less varied in their form, and especially much less in size. in calves, the mirrors show the shapes which they are afterwards to have, only they are more contracted, because the parts which they cover are but slightly developed. they are easily seen after birth; but the hair which then covers them is long, coarse, and stiff; and when this hair falls off, the calf's mirror will resemble that of the cow, but will be of less size. with calves, however, it should be stated, in addition, that the milk-mirrors are more distinctly recognized on those from cows that are well kept, and that they will generally be fully developed at two years old. some changes take place in the course of years, but the outlines of the mirror appear prominent at the time of advanced pregnancy, or, in the case of cows giving milk, at the times when the udder is more distended with milk than at others. m. mayne, who has explained and simplified the method of m. guénon, divides cows, according to the quantity which they give, into four classes: first, the very good; second, the good; third, the medium; and fourth, the bad. in the first class he places cows, both parts of whose milk mirror, the mammary--the tuft situated on the udder, the legs and the thighs--and the perinean--that on the perineum, extending sometimes more or less out upon the thighs--are large, continuous, and uniform, covering at least a great part of the perineum, the udder, the inner surface of the thighs, and extending more or less out upon the legs, as in cut a, with no interruptions, or, if any, small ones, oval in form, and situated on the posterior face of the udder. [illustration: milk-mirror [g.]] such mirrors are found on most very good cows, but may also be found on cows which can scarcely be called good, and which should be ranked in the next class. but cows, whether having very well developed mirrors or not, may be reckoned as very good, and as giving as much milk as is to be expected from their size, food, and the hygienic circumstances in which they are kept, if they present the following characteristics: veins of the perineum large, as if swollen, and visible on the exterior--as in cut a--or which can easily be made to appear by pressing upon the base of the perineum; veins of the udder large and knotted; milk-veins large, often double, equal on both sides, and forming zig-zags, under the belly. to the signs furnished by the veins and by the mirror, may be added also the following marks: a uniform, very large, and yielding udder, shrinking much in milking, and covered with soft skin and fine hair; good constitution, full chest, regular appetite, and great propensity to drink. such cows rather incline to be poor than to be fat. the skin is soft and yielding; short, fine hair; small head; fine horns; bright, sparkling eye; mild expression; feminine look; with a fine neck. cows of this first class are very rare. they give, even when small in size, from ten to fourteen quarts of milk a day; and the largest sized from eighteen to twenty-six quarts a day, and even more. just after calving, if arrived at maturity and fed with good, wholesome, moist food in sufficient quantity and quality, adapted to promote the secretion of milk, they can give about a pint of milk for every ten ounces of hay, or its equivalent, which they eat. they continue in milk for a long period. the best never go dry, and may be milked even up to the time of calving, giving from eight to ten quarts of milk a day. but even the best cows often fall short of the quantity of milk which they are able to give, from being fed on food which is too dry, or not sufficiently varied, or not rich enough in nutritive qualities, or deficient in quantity. [illustration: milk-mirror [h.]] the second class is that of _good cows_; and to this belong the best commonly found in the market and among the cow-feeders of cities. they have the mammary part of the milk-mirror well developed, but the perinean part contracted, or wholly wanting, as in cut g; or both parts of the mirror are moderately developed, or slightly indented, as in cut h. cut e belongs also to this class, in the lower part; but it indicates a cow, which--as the upper mirror, 1, indicates--dries up sooner when again in calf. these marks, though often seen in many good cows, should be considered as certain only when the veins of the perineum form, under the skin, a kind of network, which, without being very apparent, may be felt by a pressure on them; when the milk-veins on the belly are well-developed, though less knotty and less prominent than in cows of the first class; in short, when the udder is well developed, and presents veins which are sufficiently numerous, though not very large. it is necessary here, as in the preceding class, to distrust cows in which the mirror is not accompanied by large veins. this remark applies especially to cows which have had several calves, and are in full milk. they are medium or bad, let the milk-mirror be what it may, if the veins of the belly are not large, and those of the udder apparent. the general characteristics which depend on form and constitution combine, less than in cows of the preceding class, the marks of good health and excellent constitution with those of a gentle and feminine look. small cows of this class give from seven to ten or eleven quarts of milk a day, and the largest from thirteen to seventeen quarts. they can be made to give three-fourths of a pint of milk, just after calving, for every ten ounces of hay consumed, if well cared for, and fed in a manner favorable to the secretion of milk. they hold out long in milk, when they have no upper mirrors or tufts. at seven or eight months in calf, they may give from five to eight quarts of milk a day. the third class consists of _middling cows_. when the milk-mirror really presents only the mammary or lower part slightly indicated or developed, and the perinean part contracted, narrow, and irregular--as in cut k--the cows are middling. the udder is slightly developed or hard, and shrinks very little after milking. the veins of the perineum are not apparent, and those which run along the lower side of the abdomen are small, straight, and sometimes unequal. in this case the mirror is not symmetrical, and the cow gives more milk on the side where the vein is the largest. [illustration: milk-mirror [k.]] these cows have large heads, and a thick, hard skin. being ordinarily in good condition, they are beautiful to look at, and seem to be well formed. many of them are nervous and restive, and not easily approached. cows of this class give, according to size, from three or four to ten quarts of milk. they very rarely give, even in the most favorable circumstances, half a pint of milk for every ten ounces of hay which they consume. the milk diminishes rapidly, and dries up wholly the fourth or fifth month in calf. the fourth class is composed of _bad cows_. as they are commonly in good condition, these cows are often the most beautiful of the herd and in the markets. they have fleshy thighs, thick and hard skin, a large and coarse neck and head, and horns large at the base. the udder is hard, small and fleshy, with a skin covered with long, rough hair. no veins are to be seen either on the perineum or the udder, while those of the belly are slightly developed, and the mirrors are ordinarily small, as in cut l. with these characteristics, cows give only a few quarts of milk a day, and dry up in a short time after calving. some of them can scarcely nourish their calves, even when they are properly cared for and well fed. sickly habits, chronic affections of the digestive organs, the chest, the womb, and the lacteal system, sometimes greatly affect the milk secretion, and cause cows troubled with them to fall from the first or second to the third, and sometimes to the fourth class. without pushing this method of judging of the good milking qualities of cows into the objectionable extreme to which it was carried by its originator, it may be safely asserted that the milk-mirror forms an important additional mark or point for distinguishing good milkers; and it may be laid down as a rule that, in the selection of milch cows, as well as in the choice of young animals for breeders, the milk-mirror should, by all means, be examined and considered; but that we should not limit or confine ourselves exclusively to it, and that other and long-known marks should be equally regarded. there are cases, however, where a knowledge and careful examination of the form and size of the mirror become of the highest importance. it is well known that certain signs or marks of great milkers are developed, only as the capacities of the animal herself are fully and completely developed by age. the milk-veins, for instance, are never so large and prominent in heifers and young cows as in old ones, and the same may be said of the udder, and of the veins of the udder and perineum; all of which it is of great importance to observe in the selection of milch cows. those signs, then, which in cows arrived at maturity are almost sufficient in themselves to warrant a conclusion as to their merits as milkers, are, to a great extent, wanting in younger animals, and altogether in calves, as to which there is often doubt whether they shall be raised; and here a knowledge of the form of the mirror is of immense advantage, since it gives, at the outset and before any expense is incurred, a somewhat reliable means of judging of the future milking capacities of the animal; or, if a male, of the probability of his transmitting milking qualities to his offspring. [illustration: milk-mirror [l.]] it will be seen, from an examination of the points of a good milch cow that, though the same marks which indicate the greatest milking qualities may not always indicate the greatest aptitude to fatten, yet that the signs which denote good fattening qualities are included among the signs favorable to the production of milk; such as soundness of constitution, marked by good organs of digestion and respiration fineness and mellowness of the skin and hair, quietness of disposition--which inclines the animal to rest and lie down while chewing the cud--and other marks which are relied on by graziers in selecting animals to fatten. in buying dairy stock the farmer generally finds it for his interest to select young heifers, as they give the promise of longer usefulness. but it is often the case that older cows are selected with the design of using them for the dairy for a limited period, and then feeding them for the butcher. in either case, it is advisable, as a rule, to choose animals in low or medium condition. the farmer cannot commonly afford to buy fat; it is more properly his business to make it, and to have it to sell. good and well-marked cows in poor condition will rapidly gain in flesh and products when removed to better pastures and higher keeping, and they cost less in the original purchase. it is, perhaps, superfluous to add that regard should be had to the quality of the pasturage and keeping which a cow has previously had, as compared with that to which she is to be subjected. the size of the animal should also be considered with reference to the fertility of the pastures into which she is to be put. small or medium-sized animals accommodate themselves to ordinary pastures far better than large ones. where a very large cow will do well, two small ones will usually do better; while the large animal might fail entirely where two small ones would do well. it is better to have the whole herd, so far as may be, uniform in size; for, if they vary greatly, some may get more than they need, and others will not have enough. this, however, cannot always be brought about. [illustration] crossing and breeding the raising of cattle has now become a source of profit in many sections,--to a greater extent, at least, than formerly--and it becomes a matter of great practical importance to our farmers to take the proper steps to improve them. indeed, the questions--what are the best breeds, and what are the best crosses, and how shall i improve my stock--are now asked almost daily; and their practical solution would add many thousand dollars to the aggregate wealth of the farmers of the country, if they would all study their own interests. the time is gradually passing away when the intelligent practical farmer will be willing to put his cows to any bull, simply because his services may be had for twenty-five cents; for, even if the progeny is to go to the butcher, the calf sired by a pure-bred bull--particularly of a race distinguished for fineness of bone, symmetry of form, and early maturity--will bring a much higher price at the same age than a calf sired by a scrub. blood has a money value, which will, sooner or later, be generally appreciated. the first and most important object of the farmer is to get the greatest return in money for his labor and his produce; and it is for his interest to obtain an animal--a calf, for example--that will yield the largest profit on the outlay. if a calf, for which the original outlay was five dollars, will bring at the same age and on the same keep more real net profit than another, the original outlay for which was not twenty-five cents, it is certainly for the farmer's interest to make the heavier original outlay and thus secure the superior animal. setting all fancy aside, it is merely a question of dollars and cents; but one thing is certain--and that is, that no farmer can afford to keep poor stock. it eats as much, and requires nearly the same amount of care and attention, as stock of the best quality; while it is equally certain that stock of ever so good a quality, whether grade, native, or thorough-bred, will be sure to deteriorate and sink to the level of poor stock by neglect and want of proper attention. how, then, is our stock to be improved? not, certainly, by that indiscriminate crossing, with a total disregard of all well-established principles, which has thus far marked our efforts with foreign stock, and which is one prominent reason why so little improvement has been made in our dairies; nor by leaving all the results to chance, when, by a careful and judicious selection, they may be within our own control. we want cattle for distinct purposes, as for milk, beef, or labor. in a large majority of cases--especially in the dairy districts, at least, comprising the eastern and middle states--the farmer cares more for the milking qualities of his cows, especially for the quantity they give, than for their fitness for grazing, or aptness to fatten. these latter points become more important in the western and some of the southern states, where much greater attention is paid to breeding and to feeding, and where comparatively slight attention is given to the productions of the dairy. a stock of cattle which would suit one farmer might be wholly unsuited to another, and in such particular case the breeder should have some special object in view, and select his animals with reference to it. there are, however, some well-defined general principles that apply to breeding everywhere, and which, in many cases, are not thoroughly understood. to these attention will now be directed. the first and most important of the laws to be considered in this connection is that of _similarity_. it is by virtue of this law that the peculiar characters, properties, and qualities of the parents--whether external or internal, good or bad, healthy or diseased--are transmitted to their offspring. this is one of the plainest and most certain of the laws of nature. the lesson which it teaches may be stated in five words:--breed only from the best. judicious selection is indispensable to success in breeding, and this should have regard to every particular--general appearance, length of limb, shape of carcass, development of chest; in cattle, to the size, shape, and position of the udder, thickness of skin, touch, length and texture of hair, docility, and all those points which go to make up the desirable animal. not only should care be exercised to avoid _structural defects_, but especially to secure freedom from _hereditary diseases_; as both defects and diseases appear to be more easily transmissible than desirable qualities. there is, oftentimes, no obvious peculiarity of structure or appearance which suggests the possession of diseases or defects which are transmissible; and for this reason, special care and continued acquaintance are requisite in order to be assured of their absence in breeding animals; but such a tendency, although invisible or inappreciable to careless observers, must still, judging from its effects, have as real and certain an existence as any peculiarity of form or color. in neat cattle, hereditary diseases do not usually show themselves at birth; and sometimes the tendency remains latent for many years, perhaps through one or two generations, and afterward breaks out with all its former severity. the diseases which are found hereditary in cattle are scrofula, consumption, dysentery, diarrhoea, rheumatism, and malignant tumors. as these animals are less exposed to the exciting causes of disease, and less liable to be overtasked or subjected to violent changes of temperature, or otherwise put in jeopardy, their diseases are not so numerous as those of the horse, and what they have are less violent, and generally of a chronic character. with regard to hereditary diseases, it is eminently true that "an ounce of prevention is worth a pound of cure." as a general and almost invariable rule, animals possessing either defects or a tendency to disease, should not be employed for breeding. if, however, for special reasons it seems desirable to breed from one which has some slight defect of symmetry, or a faint tendency to disease--although for the latter it is doubtful whether the possession of any good qualities can fully compensate--it should be mated with one which excels in every respect in which it is itself deficient, and on no account with one which is near of kin to it. there is another law, by which that of similarity is greatly modified--the law of _variation_ or divergence. all animals possess a certain flexibility or pliancy of organization, which renders them capable of change to a greater or less extent. when in a state of nature, variations are comparatively slow and infrequent; but when in a state of domestication they occur much oftener and to a much greater extent. the greater variability in the latter case is doubtless owing, in some measure, to our domestic productions' being reared under conditions of life not so uniform as, and different from, those to which the parent species was exposed in a state of nature. among what are usually reckoned the more active causes of variation may be named _climate_, _food_, and _habit_. animals in a cold climate are provided with a thicker covering of hair than in warmer ones. indeed, it is said that in some of the tropical provinces of south america, there are cattle which have an extremely rare and fine fur, in place of the ordinary pile of hair. the supply of food, whether abundant or scanty, is one of the most efficient causes of variation known to be within the control of man. a due consideration of the natural effects of climate and food is a point worthy the careful attention of the stock-husbandman. if the breeds employed be well adapted to the situation, and the capacity of the soil be such as to feed them fully, profit may be safely anticipated. animals are to be regarded as machines for converting herbage into money. the bestowal of food sufficient, both in amount and quality, to enable animals to develop all the excellencies inherent in them, and yield all the profit of which they are capable, is something quite distinct from undue forcing of pampering. the latter process may produce wonderful animals to look at, but neither useful nor profitable ones, and there is danger of thus producing a most undesirable variation, since in animals the process may be carried far enough to produce barrenness. instances are not wanting, particularly among the more recent improved short-horns, of impotency among the males and of barrenness among the females; and in some cases where the latter have borne calves, they have failed to secrete sufficient milk for their nourishment. impotency in bulls of various breeds has, in many instances, occurred from too high feeding, especially when connected with a lack of sufficient exercise. a working bull, though perhaps not so pleasing to the eye as a fat one, is a surer stock-getter; and his progeny is more likely to inherit full health and vigor. _habit_ has a decided influence toward producing variations. we find in domestic animals that use--or the demand created by habit--is met by a development or change in the organization adapted to the requirement. for instance, with cows in a state of nature, or where required only to suckle their young, the supply of milk is barely fitted to the requirement. if more is desired, and the milk is drawn completely and regularly, the yield is increased and continued longer. by keeping up the demand there is induced, in the next generation, a greater development of the secreting organs, and more milk is given. by continuing the practice, by furnishing the needful conditions of suitable food and the like, and by selecting in each generation those animals showing the greatest tendency toward milk, a breed specially adapted for the dairy may be established. it is just by this mode that the ayrshires have, within the past century, been brought to be what they are--a breed giving more good milk upon a certain amount of food than any other. [illustration: ready for action.] it is a fact too well established to be controverted, that the first male produces impressions upon subsequent progeny by other males. to what extent this principle holds, it is impossible to say. although the instances in which it is known to be of a very marked and obvious character may be comparatively few, yet there is ample reason to believe that, although in a majority of cases the effect may be less noticeable, it is not less real; and it therefore demands the special attention of breeders. the knowledge of this law furnishes a clue to the cause of many of the disappointments of which practical breeders often complain, and of many variations otherwise unaccountable, and it suggests particular caution as to the first male employed in the coupling of animals--a matter which has often been deemed of little consequence in regard to cattle, inasmuch as fewer heifers' first calves are reared, than those are which are borne subsequently. the phenomenon--or law, as it is sometimes called--of atavism, or _ancestral influence_, is one of considerable practical importance, and well deserves the careful attention of the breeder of farm stock. every one is aware that it is by no means unusual for a child to resemble its grandfather, or grandmother, or even some ancestor still more remote, more than it does either its own father or mother. the same occurrence is found among our domestic animals, and oftener in proportion as the breeds are crossed or mixed up. among our common stock of neat cattle, or natives--originating, as they did, from animals brought from england, scotland, denmark, france, and spain, each possessing different characteristics of form, color, and use, and bred, as our common stock has usually been, indiscriminately together, with no special object in view, with no attempt to obtain any particular type or form, or to secure adaptation for any particular purpose--frequent opportunities are afforded of witnessing the results of this law of hereditary transmission. so common, indeed, is its occurrence, that the remark is often made, that, however good a cow may be, there is no telling beforehand what sort of a calf she may have. the fact is sufficiently obvious, that certain peculiarities often lie dormant for a generation or two and then reappear in subsequent progeny. stockmen often speak of it as "breeding back," or "crying back." the lesson taught by this law is very plain. it shows the importance of seeking thorough-bred or well-bred animals; and by these terms are simply meant such as are descended from a line of ancestors in which for many generations the desirable forms, qualities, and characteristics have been _uniformly shown_. in such a case, even if ancestral influence does come in play, no material difference appears in the offspring, the ancestors being all essentially alike. from this standpoint we best perceive in what consists the money value of a good "pedigree." this is valuable, in proportion as it shows an animal to be descended, not only from such as are purely of its own race or breed, but also from such individuals of that breed as were specially noted for the excellencies for which that particular breed is esteemed. probably the most distinctly marked evidence of ancestral influence among us, is to be found in the ill-begotten, round-headed calves, not infrequently dropped by cows of the common mixed kind, which, if killed early, make very blue veal, and if allowed to grow up, become exceedingly profitless and unsatisfactory beasts; the heifers being often barren, the cows poor milkers, the oxen dull, mulish beasts, yielding flesh of very dark color, of ill flavor and destitute of fat. _the relative influence_ of the male and female parents upon the characteristics of progeny has long been a fruitful subject of discussion among breeders. it is found in experience that progeny sometimes resembles one parent more than the other--sometimes there is an apparent blending of the characteristics of both--sometimes a noticeable dissimilarity to either, though always more or less resemblance somewhere--and sometimes the impress of one may be seen upon a portion of the organization of the offspring, and that of the other parent upon another portion; yet we are not authorized from such discrepancies to conclude that it is a matter of chance; for all of nature's operations are conducted in accordance with fixed laws, whether we be able fully to discover them or not. the same causes always produce the same results. in this case, not less than in others, there are, beyond all doubt, certain fixed laws; and the varying results which we see are easily and sufficiently accounted for by the existence of conditions or modifying influences not fully open to our observation. it may be stated, on the whole--as a result of the varied investigations to which this question has given rise--that the evidence, both from observation and the testimony of the best practical breeders, goes to show that each parent usually contributes certain portions of the organization to the offspring, and that each has a modifying influence upon the other. facts also show that the same parent does not always contribute the same portions, but that the order is at times, and not rarely, reversed. where animals are of distinct species or breeds, transmission is usually found to be in harmony with the principle, that the male gives mostly the outward form and locomotive system, and the female chiefly the interior system, constitution and the like. where the parents are of the same breed, it appears that the proportions contributed by each are governed, in a large measure, by the condition of each in regard to age and vigor, or by virtue of individual potency or superiority of physical endowment. this potency or power of transmission, seems to be legitimately connected with high breeding, or the concentration of fixed qualities, obtained by continued descent for many generations from such only as possess in the highest degree the qualities desired. practically, the knowledge obtained dictates in a most emphatic manner that every stock-grower use his utmost endeavor to obtain the services of the best sires; that is, the best for the ends and purposes in view--that he depend chiefly on the sire for outward form and symmetry--and that he select dams best calculated to develop the good qualities of the male, depending chiefly upon these for freedom, from internal disease, for hardihood and constitution, and, generally, for all qualities dependent upon the vital or nutritive system. the neglect of the qualities of the dam, which is far too common--miserably old and inferior animals being often employed--cannot be too strongly censured. with regard to the laws which regulate the sex of the progeny very little is known. many and extensive observations have been made, without reaching any definite conclusion. nature seems to have provided that the number of each sex; produced, shall be nearly equal; but by what means this result is attained, has not as yet been discovered. it has long been a disputed point, whether the system of _breeding in-and-in_, or the opposite one of frequent crossing, has the greater tendency to improve the character of stock this term, in-and-in, is often very loosely used and as variously understood. some confine the phrase to the coupling of those of exactly the same blood, as brothers and sisters, while others include in it breeding from parents and offsprings; and others still employ it to embrace those of a more distant relationship. for the last, the term breeding-in, or close breeding, is generally deemed more suitable. the current opinion is decidedly against the practice of breeding from any near relatives; it being usually found that degeneracy follows, and often to a serious degree; but it is not proved that this degeneracy, although very common and even usual, is yet a necessary consequence. that ill effects follow, in a majority of cases, is not to be doubted; but this is easily and sufficiently accounted for upon quite other grounds. perhaps, however, the following propositions may be safely stated: that in general practice, with the grades and mixed animals common in the country, _close-breeding should be scrupulously avoided_ as highly detrimental. it is better _always_ to avoid breeding from near relatives whenever stock-getters of the same breed and of equal merit can be obtained which are not related. yet, where this is not possible, or where there is some desirable and clearly defined purpose in view--as the fixing and perpetuating of some valuable quality in a particular animal not common to the breed--and the breeder possesses the knowledge and skill needful to accomplish his purpose, and the animals are perfect in health and development, close breeding may be practised with advantage. the practice of _crossing_, like that of close breeding, has its strong and its weak side. judiciously practised, it offers a means of providing animals _for the butcher_, often superior to, and more profitable than, those of any pure breed. it is also admissible as the foundation of a systematic and well-considered attempt to establish a new breed. but when crossing is practised injudiciously and indiscriminately, and especially when so done for the purpose of procuring _breeding animals_, it is scarcely less objectionable than careless in-and-in breeding. [illustration: a sprightly youth.] the profitable style of breeding for the great majority of farmers to adopt, is neither to cross nor to breed from close affinities--except in rare instances, and for some specific and clearly understood purpose--but to _breed in the line_; that is, to select the breed or race best adapted to fulfil the requirement demanded, whether it be for the dairy, for labor, or for such combination of these as can be had without too great a sacrifice of the principal requisite, and then to procure a _pure-bred_ male of the kind determined upon, and breed him to the females of the herd; and if these be not such as are calculated to develop his qualities, endeavor by purchase or exchange to procure such as will. let the progeny of these be bred to another _pure-bred_ male of the same breed, but as distantly related to the first as may be. let this plan be faithfully pursued, and, although we cannot, without the intervention of well-bred females, procure stock purely of the kind desired, yet in several generations--if proper care be given to the selection of males, that each one be such as to retain and improve upon the points gained by his predecessor--the stock, for most practical purposes, will be as good as if thorough-bred. if this plan were generally adopted, and a system of letting or exchanging males established, the cost might be brought within the means of most persons, and the advantages which would accrue would be almost beyond belief. a brief summing-up of the foregoing principles may not be inappropriate here. the law of similarity teaches us to select animals for breeding which possess the desired forms and qualities in the greatest perfection and best combination. regard should be had, not only to the more obvious characteristics, but also to such hereditary traits and tendencies as may be hidden from cursory observation and demand careful and thorough investigation. from the hereditary nature of all characteristics, whether good or bad, we learn the importance of having all desirable qualities _thoroughly inbred_; or, in other words, so firmly in each generation that the next is warrantably certain to present nothing worse--that no ill results follow from breeding back to some inferior ancestor--that all undesirable traits or points be, so far as possible, _bred-out_. so important is this consideration, that, in practice, it is decidedly preferable to employ a male of ordinary external appearance--provided his ancestry be all which is desired--rather than a grade, or cross-bred animal, although the latter be greatly his superior in personal beauty. a knowledge of the law of variation teaches us to avoid, for breeding purposes, such animals as exhibit variations unfavorable to the purpose in view; to endeavor to perpetuate every real improvement gained; as well as to secure, as far as practicable, the conditions necessary to induce or continue any improvement, such as general treatment, food, climate, habits, and the like. where the parents do not possess the perfections desired, selections for coupling should be made with critical reference to correcting the faults or deficiencies of one by corresponding excellencies in the other. to correct defects, too much must not be attempted at once. pairing those very unlike oftener results in loss than gain. avoid all extremes, and endeavor by moderate degrees to attain the end desired. crossing, between different breeds, for the purpose of obtaining animals for the shambles, may be advantageously practised to a considerable extent, but not for the production of breeding animals. as a general rule, cross-bred males should not be employed for propagation, and cross-bred females should be served by thorough-bred males. in ordinary practice, breeding from near relatives is to be scrupulously avoided. for certain purposes, under certain conditions and circumstances, and in the hands of a skillful breeder, it may be practised with advantage--but not otherwise. in a large majority of cases--other things being equal--we may expect in progeny the outward form and general structure of the sire, together with the internal qualities, constitution, and nutritive system of the dam; each, however, modified by the other. particular care should always be taken that the male by which the dam first becomes pregnant is the best which can be obtained; also, that at the time of sexual congress both are in vigorous health. breeding animals should not be allowed to become fat, but always kept in thrifty condition; and such as are intended for the butcher should never be fat but once. in deciding with what breeds to stock a farm, endeavor to select those best adapted to its surface, climate, and degree of fertility; also, with reference to probable demand and proximity to markets. no expense incurred in procuring choice animals for propagation, no amount of skill in breeding, can supersede, or compensate for, a lack of liberal feeding and good treatment. the better the stock, the better care they deserve. pregnancy the symptoms of pregnancy in its early stage were formerly deemed exceedingly unsatisfactory. the period of being in season--which commonly lasts three or four days, and then ceases for a while, and returns in about three weeks--might entirely pass over; and, although it was then probable that conception had taken place, yet in a great many instances the hopes of the breeder were disappointed. it was not until between the third and fourth month, when the belly began to enlarge--or, in many cases, considerably later--and when the motions of the foetus might be seen, or, at all events, felt by pressing on the right flank, that the farmer could be assured that his cow was in calf. that greatest of improvements in veterinary practice, the application of the ear to the chest and belly of various animals, in order to detect by the different sounds--which after a short time, will be easily recognized--the state of the circulation through most of the organs, and consequently, the precise seat and degree of inflammation and danger, has now enabled the breeder to ascertain the existence of pregnancy at as early a stage as six or eight weeks. the beating of the heart of the calf may then be distinctly heard, twice, or more than twice, as frequent as that of the mother; and each pulsation will betray the singular double beating of the foetal heart. this will also be accompanied by the audible rushing of the blood through the vessels of the placenta. the ear should be applied to the right flank, beginning on the higher part of it, and gradually shifting downward and backward. these sounds will thus soon be heard, and cannot be mistaken. treatment before calving. little alteration needs to be made in the management of the cow for the first seven months of pregnancy; except that, as she has not only to yield milk for the profit of the farmer, but to nourish the growing foetus within, she should be well, yet not too luxuriantly, fed. the half-starved cow will not adequately discharge this double duty, nor provide sufficient nutriment for the calf when it has dropped; while the cow in high condition will be dangerously disposed to inflammation and fever, when, at the time of parturition, she is otherwise so susceptible of the power of every stimulus. if the season and the convenience of the farmer will allow, she will be better at pasture, at least for some hours each day than when confined altogether to the cow-house. at a somewhat uncertain period before she calves, there will be a new secretion of milk for the expected little one; and under the notion of somewhat recruiting her strength, in order better to enable her to discharge her new duty--but more from the uniform testimony of experience that there is danger of local inflammation, general fever, garget in the udder, and puerperal fever, if the new milk descends while the old milk continues to flow--it has been usual to let the cow _go dry_ for some period before parturition. farmers and breeders have been strangely divided as to the length of this period. it must be decided by circumstances. a cow in good condition may be milked for a much longer period than a poor one. her abundance of food renders a period of respite almost unnecessary; and all that needs to be taken care of, is that the old milk should be fairly gone before the new milk springs. in such a cow, while there is danger of inflammation from the sudden rush of new milk into a bag already occupied, there is almost always considerable danger of indurations and tumors in the teats from the habit of secretion being too long suspended. the emaciated and over-milked beast, however, must rest a while before she can again advantageously discharge the duties of a mother. if the period of pregnancy were of equal length at all times and in all cows, the one that has been well fed might be milked until within a fortnight or three weeks of parturition, while a holiday of two months should be granted to the poorer beast; but as there is much irregularity about the time of gestation, it may be prudent to take a month or five weeks, as the average period. the process of parturition is necessarily one that is accompanied with a great deal of febrile excitement; and, therefore, when it nearly approaches, not only should a little care be taken to lessen the quantity of food, and to remove that which is of a stimulating action, but a mild dose of physic, and a bleeding regulated by the condition of the animal, will be very proper precautionary measures. a moderately open state of the bowels is necessary at the period of parturition in the cow. during the whole time of pregnancy her enormous stomach sufficiently presses upon and confines the womb; and that pressure may be productive of injurious and fatal consequences, if at this period the rumen is suffered to be distended by innutritious food, or the manyplus takes on that hardened state to which it is occasionally subject. breeders have been sadly negligent in this respect. the springing of the udder, or the rapid enlargement of it from the renewed secretion of milk--the enlargement of the external parts of the bearing (the former, as has been said by some, in old cows, and the latter in young ones)--the appearance of a glaring discharge from the bearing--the evident dropping of the belly, with the appearance of leanness and narrowness between the shape and the udder--a degree of uneasiness and fidgetiness--moaning occasionally--accelerated respiration--all these symptoms will announce that the time of calving is not far off. the cow should be brought near home, and put in some quiet, sheltered place. in cold or stormy weather she should be housed. her uneasiness will rapidly increase--she will be continually getting up and lying down--her tail will begin to be elevated and the commencement of the labor-pains will soon be evident. in most cases the parturition will be natural and easy, and the less the cow is disturbed or meddled with, the better. she will do better without help than with it; but she should be watched, in order to see that no difficulty occurs which may require aid and attention. in cases of difficult parturition the aid of a skillful veterinary surgeon may be required. [illustration] feeding and management no branch of dairy farming can compare in importance with the management of cows. the highest success will depend upon it, whatever breed be selected, and whatever amount of care and attention be given to the points of the animals; for experience will show that very little milk comes out of the bag, that is not first put into the throat. it is poor economy, therefore, to attempt to keep too many cows for the amount of feed one has; for it will generally be found that one good cow well-bred and well fed will yield as much as two ordinary cows kept in the ordinary way; while a saving is effected both in labor and room required, and in the risks on the capital invested. if an argument for the larger number on poorer feed is urged on the ground of the additional manure--which is the only basis upon which it can be put--it is enough to say that it is a very expensive way of making manure. it is not too strong an assertion, that a proper regard to profit and economy would require many an american farmer to sell off nearly half of his cows, and to feed the whole of his hay and roots hitherto used into the remainder. an animal, to be fully fed and satisfied, requires a quantity of food in proportion to its live weight. no feed is complete that does not contain a sufficient amount of nutritive elements; hay, for example, being more nutritive than straw, and grains than roots. the food, too, must possess a bulk sufficient to fill up to a certain degree the organs of digestion of the stomach; and, to receive the full benefit of its food, the animal must be wholly satisfied--since, if the stomach is not sufficiently distended, the food cannot be properly digested, and of course many of the nutritive principles which it contains cannot be perfectly assimilated. an animal regularly fed eats till it is satisfied, and no more than is requisite. a part of the nutritive elements in hay and other forage plants is needed to keep an animal on its feet--that is, to keep up its condition--and if the nutrition of its food is insufficient for this, the weight decreases, and if it is more than sufficient the weight increases, or else this excess is consumed in the production of milk or in labor. about one sixtieth of their live weight in hay, or its equivalent, will keep horned cattle on their feet; but, in order to be completely nourished, they require about one thirtieth in dry substances, and four thirtieths in water, or other liquid contained in their food. the excess of nutritive food over and above what is necessary to sustain life will go, in milch cows, generally to the production of milk, or to the growth of the foetus, but not in all cows to an equal extent; the tendency to the secretion of milk being much more developed in some than in others. with regard, however, to the consumption of food in proportion to the live weight of the animal, it must be taken, in common with all general principles, with some qualifications. the proportion is probably not uniform as applied to all breeds indiscriminately, though it may be more so as applied to animals of the same breed. the idea of some celebrated stock-raisers has been that the quantity of food required depends much upon the shape of the barrel; and it is well known that an animal of a close, compact, well-rounded barrel, will consume less than one of an opposite make. the variations in the yield of milch cows are caused more by the variations in the nutritive elements of their food than by a change of the form in which it is given. a cow, kept through the winter on mere straw, will cease to give milk; and, when fed in spring on green forage, will give a fair quantity of milk. but she owes the cessation and restoration of the secretion, respectively, to the diminution and increase of her nourishment, and not at all to the change of form, or of outward substance in which the nutriment is administered. let cows receive through winter nearly as large a proportion of nutritive matter as is contained in the clover, lucerne, and fresh grass which they eat in summer, and, no matter in what precise substance or mixture that matter be contained, they will yield a winter's produce of milk quite as rich in caseine and butyraceous ingredients as the summer's produce, and far more ample in quantity than almost any dairyman with old-fashioned notions would imagine to be possible. the great practical error on this subject consists, not in giving wrong kinds of food, but in not so proportioning and preparing it as to render an average ration of it equally rich in the elements of nutrition, and especially in nitrogenous elements, as an average ration of the green and succulent food of summer. we keep too much stock for the quantity of good and nutritious food which we have for it; and the consequence is, that cows are, in nine cases out of ten, poorly wintered, and come out in the spring weakened, if not, indeed, positively diseased, and a long time is required to bring them into a condition to yield a generous quantity of milk. it is a hard struggle for a cow reduced in flesh and in blood to fill up the wasted system with the food which would otherwise have gone to the secretion of milk; but, if she is well fed, well housed, well littered, and well supplied with pure, fresh water, and with roots, or other _moist_ food, and properly treated to the luxury of a frequent carding, and constant kindness, she comes out ready to commence the manufacture of milk under favorable circumstances. _keep the cows constantly in good condition_, ought, therefore, to be the motto of every dairy farmer, posted up over the barn, and on and over the stalls, and over the milk-room, and repeated to the boys whenever there is danger of forgetting it. it is the great secret of success; and the difference between success and failure turns upon it. cows in milk require more food in proportion to their size and weight than either oxen or young cattle. in order to keep cows in milk well and economically, regularity is next in importance to a full supply of wholesome and nutritious food. the animal stomach is a very nice chronometer, and it is of the utmost importance to observe regular hours in feeding, cleaning, and milking. this is a point, also, in which very many farmers are at fault--feeding whenever it happens to be convenient. the cattle are thus kept in a restless condition, constantly expecting food when the keeper enters the barn; while, if regular hours are strictly adhered to, they know exactly when they are to be fed, and they rest quietly till the time arrives. if one goes into any well-regulated dairy establishment an hour before feeding, scarcely an animal will rise to its feet; while; if it happens to be the hour of feeding, the whole herd will be likely to rise and seize their food with an avidity and relish not to be mistaken. with respect to the exact nurture to be pursued, no rule could be prescribed which would apply to all cases; and each individual must be governed much by circumstances, both regarding the particular kinds of feed at different seasons of the year, and the system of feeding. it has been found--it may be stated--in the practice of the most successful dairymen, that, in order to encourage the largest secretion of milk in stalled cows, one of the best courses is, to feed in the morning, either at the time of milking--which is preferred by many--or immediately after, with cut feed, consisting of hay, oats, millet, or cornstalks, mixed with shorts, and indian linseed, or cotton-seed meal, thoroughly moistened with water. if in winter, hot or warm water is far better than cold. if given at milking-time, the cows will generally give down their milk more readily. the stalls and mangers should first be thoroughly cleansed. [illustration: the family pets.] roots and long hay may be given during the day; and at the evening milking, or directly after, another generous meal of cut feed, well moistened and mixed, as in the morning. no very concentrated food, like grains alone, or oil-cakes, should be fed early in the morning on an empty stomach, although it is sanctioned by the practice in the london milk-dairies. the processes of digestion go on best when the stomach is sufficiently distended; and for this purpose the bulk of food is almost as important as the nutritive qualities. the flavor of some roots, as cabbages and turnips, is more apt to be imparted to the flesh and milk when fed on an empty stomach than otherwise. after the cows have been milked and have finished their cut feed, they are carded and curried down, in well-managed dairies, and then either watered in the stall--which, in very cold or stormy weather, is far preferable--or turned out to water in the yard. while they are out, if they are let out at all, the stables are put in order; and, after tying them up, they are fed with long hay, and left to themselves till the next feeding time. this may consist of roots--such as cabbages, beets, carrots, or turnips sliced--or of potatoes, a peck, or--if the cows are very large--a half-bushel each, and cut feed again at the evening milking, as in the morning; after which, water in the stall, if possible. the less cows are exposed to the cold of winter, the better. they eat less, thrive better, and give more milk, when kept housed all the time, than when exposed to the cold. a case is on record, where a herd of cows, which had usually been supplied from troughs and pipes in the stalls, were, on account of an obstruction in the pipes, obliged to be turned out thrice a day to be watered in the yard. the quantity of milk instantly decreased, and in three days the diminution became very considerable. after the pipes were mended, and the cows again watered, as before, in their stalls, the flow of milk returned. this, however, must be governed much by the weather; for in very mild and warm days it may be judicious not only to let them out, but to allow them to remain out for a short time, for the purpose of exercise. any one can arrange the hour for the several processes named above, to suit himself; but, when once fixed, it should be rigidly and regularly followed. if the regular and full feeding be neglected for even a day, the yield of milk will immediately decline, and it will be very difficult to restore it. it may be safely asserted, as the result of many trials and long practice, that a larger flow of milk follows a complete system of regularity in this respect than from a higher feeding where this system is not adhered to. one prime object which the dairyman should keep constantly in view is, to maintain the animal in a sound and healthy condition. without this, no profit can be expected from a milch cow for any considerable length of time; and with a view to this, there should be an occasional change of food. but, in making changes, great care is requisite in order to supply the needful amount of nourishment, or the cow will fall off in flesh, and eventually in milk. it should, therefore, be remembered that the food consumed goes not alone to the secretion of milk, but also to the growth and maintenance of the bony structure, the flesh, the blood, the fat, the skin, and the hair, and in exhalations from the body. these parts of the body consist of different organic constituents. some are rich in nitrogen, as the fibrin of the blood and albumen; others destitute of it, as fat; some abound in inorganic salts, phosphate of lime, and salts of potash. to explain how the constant waste of these substances may be supplied, a celebrated chemist observes that the albumen, gluten, caseine, and other nitrogenized principles of food, supply the animal with the materials requisite for the formation of muscle and cartilage; they are, therefore, called flesh-forming principles. fats, or oily matters of the food, are used to lay on fat, or for the purpose of sustaining respiration. starch, sugar, gum, and a few other non-nitrogenized substances, consisting of carbon, oxygen, and hydrogen, supply the carbon given off in respiration, or they are used for the production of fat. phosphate of lime and magnesia in food principally furnish the animal with the materials of which the bony skeleton of its body consists. saline substances--chlorides of sodium and potassium, sulphate and phosphate of potash and soda, and some other mineral matters occurring in food--supply the blood, juice of flesh, and various animal juices, with the necessary mineral constituents. the healthy state of an animal can thus only be preserved by a mixed food; that is, food which contains all the proximate principles just noticed. starch or sugar alone cannot sustain the animal body, since neither of them furnishes the materials to build up the fleshy parts of the animal. when fed on substances in which an insufficient quantity of phosphates occurs, the animal will become weak, because it does not find any bone-producing principle in its food. due attention should, therefore, be paid by the feeder to the selection of food which contains all the kinds of matter required, nitrogenized as well as non-nitrogenized, and mineral substances; and these should be mixed together in the proportion which experience points out as best for the different kinds of animals, or the particular purpose for which they are kept. relative to the nutrition of cows for dairy purposes, milk may be regarded as a material for the manufacture of butter and cheese; and, according to the purpose for which the milk is intended to be employed, whether for the manufacture of butter or the production of cheese, the cow should be differently fed. butter contains carbon, oxygen, and hydrogen, and no nitrogen. cheese, on the contrary, is rich in nitrogen. food which contains much fatty matter, or substances which in the animal system are readily converted into fat, will tend to increase the proportion of cream in milk. on the other hand, the proportion of caseine or cheesy matter in milk is increased by the use of highly nitrogenized food. those, then, who desire much cream, or who produce cream for the manufacture of butter, select food likely to increase the proportion of butter in the milk. on the contrary, where the principal object is the production of milk rich in curd--that is, where cheese is the object of the farmer--clover, peas, bran-meal, and other plants which abound in legumine--a nitrogenized organic compound, almost identical in properties and composition with caseine, or the substance which forms the curd of milk--will be selected. and so the quality, as well as the quantity, of butter in the milk, depends on the kind of food consumed and on the general health of the animal. cows fed on turnips in the stall always produce butter inferior to that of cows living upon the fresh and aromatic grasses of the pastures. succulent food in which water abounds--the green grass of irrigated meadows, green clover, brewers' and distillers' refuse, and the like--increases the quantity, rather than the quality, of the milk; and by feeding these substances the milk-dairyman studies his own interest, and makes thin milk without diluting it with water--though, in the opinion of some, this may be no more legitimate than watering the milk. but, though the yield of milk may be increased by succulent or watery food, it should be given so as not to interfere with the health of the cow. food rich in starch, gum, or sugar, which are the respiratory elements, an excess of which goes to the production of fatty matters, increases the butter in milk. quietness promotes the secretion of fat in animals and increases the butter. cheese will be increased by food rich in albumen, such as the leguminous plants. [illustration: buying cattle.] the most natural, and of course the healthiest, food for milch cows in summer, is the green grass of the pastures; and when these fail from drought or over-stocking, the complement of nourishment may be made up with green clover, green oats, barley, millet, or corn-fodder and cabbage-leaves, or other succulent vegetables; and if these are wanting, the deficiency may be partly supplied with shorts, indian-meal, linseed or cotton-seed meal. green grass is more nutritious than hay, which always loses somewhat of its nutritive properties in curing; the amount of the loss depending chiefly on the mode of curing, and the length of exposure to sun and rain. but, apart from this, grass is more easily and completely digested than hay, though the digestion of the latter may be greatly aided by cutting and moistening, or steaming; and by this means it is rendered more readily available, and hence far better adapted to promote a large secretion of milk--a fact too often overlooked even by many intelligent farmers. in autumn, the best feed will be the grasses of the pastures, so far as they are available, green-corn fodder, cabbage, carrot, and turnip leaves, and an addition of meal or shorts. toward the middle of autumn, the cows fed in the pastures will require to be housed regularly at night, especially in the more northern latitudes, and put, in part at least, upon hay. but every farmer knows that it is not judicious to feed out the best part of his hay when his cattle are first put into the barn, and that he should not feed so well in the early part of winter that he cannot feed better as the winter advances. at the same time, it should always be borne in mind that the change from grass to a poor quality of hay or straw, for cows in milk, should not be too sudden. a poor quality of dry hay is far less palatable in the early part of winter, after the cows are taken from grass, than at a later period; and, if it is resorted to with milch cows, will invariably lead to a falling off in the milk, which no good feed can afterward wholly restore. it is desirable, therefore, for the farmer to know what can be used instead of his best english or upland meadow hay, and yet not suffer any greater loss in the flow of milk, or in condition, than is absolutely necessary. in some sections of the eastern states, the best quality of swale hay will be used; and the composition of that is as variable as possible, depending on the varieties of the grasses of which it was made, and the manner of curing. but, in other sections, many will find it necessary to use straw and other substitutes. taking good english or meadow hay as the standard of comparison, and calling that one, 4.79 times the weight of rye-straw, or 3.83 times the weight of oat-straw, contains the same amount of nutritive matter; that is, it would take 4.79 times as good rye-straw to produce the same result as good meadow hay. in winter, the best food for cows in milk will be good sweet meadow hay, a part of which should be cut and moistened with water--as all inferior hay or straw should be--with an addition of root-crops, such as turnips, carrots, parsnips, potatoes, mangold-wurtzel, with shorts, oil-cake, indian meal, or bean meal. it is the opinion of most successful dairymen that the feeding of moist food cannot be too highly recommended for cows in milk, especially to those who desire to obtain the largest quantity. hay cut and thoroughly moistened becomes more succulent and nutritive, and partakes more of the nature of green grass. as a substitute for the oil-cake, hitherto known as an exceedingly valuable article for feeding stock, there is probably nothing better than cotton-seed meal. this is an article whose economic value has been but recently made known, but which, from practical trials already made, has proved eminently successful as food for milch cows. chemists have decided that its composition is not inferior to that of the best flaxseed cake, and that in some respects its agricultural value surpasses that of any other kind of oil-cake. it has been remarked by chemists, in this connection, that the great value of linseed-cake, as an adjunct to hay, for fat cattle and milch cows, has been long recognized; and that it is undeniably traceable, in the main, to three ingredients of the seeds of the oil-yielding plants. the value of food depends upon the quantities of matters it contains which may be appropriated by the animal which consumes the food now, it is proved that the fat of animals is derived from the starch, gum, and sugar, and more directly and easily from the oil of the food. these four substances, then, are fat-formers. the muscles, nerves, and tendons of animals, the brine of their blood and the curd of their milk, are almost identical in composition with, and strongly similar in many of their properties to, matters found in all vegetables, but chiefly in such as form the most concentrated food. these blood (and muscle) formers are characterized by containing about fifteen and a half per cent. of nitrogen; and hence are called nitrogenous substances. they are, also, often designated as the albuminous bodies. the bony framework of the animal owes its solidity to phosphate of lime, and this substance must be furnished by the food. a perfect food must supply the animal with these three classes of bodies, and in proper proportions. the addition of a small quantity of a food, rich in oil and albuminous substances, to the ordinary kinds of feed, which contain a large quantity of vegetable fibre or woody matter, more or less indigestible, but, nevertheless, indispensable to the herbivorous animals, their digestive organs being adapted to a bulky food, has been found highly advantageous in practice. neither hay alone nor concentrated food alone gives the best results. a certain combination of the two presents the most advantages. some who have used cotton-seed cake have found difficulty in inducing cattle to eat it. by giving it at first in small doses, mixed with other palatable food, they soon learn to eat it with relish. cotton-seed cake is much richer in oils and albuminous matters than the linseed cake. a correspondingly less quantity will therefore be required. three pounds of this cotton-seed cake are equivalent to four of linseed cake of average quality. during the winter season, as has been already remarked, a frequent change of food is especially necessary, both as contributions to the general health of animals, and as a means of stimulating the digestive organs, and thus increasing the secretion of milk. a mixture used as cut feed and well moistened is now especially beneficial, since concentrated food, which would otherwise be given in small quantities, may be united with larger quantities of coarser and less nutritive food, and the complete assimilation of the whole be better secured. on this subject it has been sensibly observed that the most nutritious kinds of food produce little or no effect when they are not digested by the stomach, or if the digested food is not absorbed by the lymphatic vessels, and not assimilated by the various parts of the body. now, the normal functions of the digestive organs not only depend upon the composition of the food, but also on its volume. the volume or bulk of the food contributes to the healthy action of the digestive organs, by exercising a stimulating effect upon the nerves which govern them. thus the whole organization of ruminating animals necessitates the supply of bulky food, to keep the animal in good condition. feed sweet and nutritious food, therefore, frequently, regularly, and in small quantities, and change it often, and the best results may be confidently anticipated. if the cows are not in milk, but are to come in in the spring, the difference in feeding should be rather in the quantity than the quality, if the highest yield is to be expected from them during the coming season. the most common feeding is hay alone, and oftentimes very poor hay at that. the main point is to keep the animal in a healthy and thriving condition, and not to suffer her to fail in flesh; and with this object, some change and variety of food are highly important. [illustration: calling in the cattle.] toward the close of winter, a herd of cows will begin to come in, or approach their time of calving. care should then be taken not to feed too rich or stimulating food for the last week or two before this event, as it is often attended with ill consequences. a plenty of hay, a few potatoes or shorts, and pure water will suffice. in spring, the best feeding for dairy cows will be much the same as that for winter; the roots in store over winter, such as carrots, mangold wurtzel, turnips, and parsnips, furnishing very valuable aid in increasing the quantity and improving the quality of milk. toward the close of this season, and before the grass of pastures is sufficiently grown to make it judicious to turn out the cows, the best dairymen provide a supply of green fodder in the shape of winter rye, which, if cut while it is tender and succulent, and before it is half grown, will be greatly relished. unless cut young, however, its stalk soon becomes hard and unpalatable. all practical dairymen agree in saying that a warm and well-ventilated barn is indispensable to the promotion of the highest yield of milk in winter; and most agree that cows in milk should not be turned out, even to drink, in cold weather; all exposure to cold tending to lessen the yield of milk. in the london dairies, in which, of course, the cows are fed so as to produce the largest flow of milk, the treatment is as follows: the cows are kept at night in stalls. about three a. m. each has a half-bushel of grains. when milking is finished, each receives a bushel of turnips (or mangolds), and shortly afterward, one tenth of a truss of hay of the best quality. this feeding occurs before eight a. m., when the animals are turned into the yard. four hours after, they are again tied up in their stalls, and have another feed of grains. when the afternoon milking is over (about three p. m.), they are fed with a bushel of turnips, and after the lapse of an hour, hay is given them as before. this mode of feeding usually continues throughout the cool season, or from november to march. during the remaining months they are fed with grains, tares, and cabbages, and a proportion of rowen, or second-cut hay. they are supplied regularly until they are turned out to grass, when they pass the whole of the night in the field. the yield is about six hundred and fifty gallons a year for each cow. mr. harley--whose admirable dairy establishment was erected for the purpose of supplying the city of glasgow with a good quality of milk, and which has contributed more than any thing else to improve the quality of the milk furnished to all the principal cities of great britain--adopted the following system of feeding with the greatest profit: in the early part of the summer, young grass and green barley, the first cutting especially, mixed with a large proportion of old hay or straw, and a good quantity of salt to prevent swelling, were used. as summer advanced, less hay and straw were given, and as the grass approached ripeness, they were discontinued altogether; but young and wet clover was never given without an admixture of dry provender. when grass became scarce, young turnips and turnip leaves were steamed with hay, and formed a good substitute. as grass decreased, the turnips were increased, and at length became a complete substitute. as the season advanced, a large proportion of distillers' grains and wash was given with other food, but these were found to have a tendency to make the cattle grain-sick; and if this feeding were long-continued, the health of the cows became affected. boiled linseed and short-cut wheat straw mixed with the grains, were found to prevent the cows from turning sick. as spring approached, swedish turnips, when cheap, were substituted for yellow turnips. these two roots, steamed with hay and other mixtures, afforded safe food till grass was again in season. when any of the cows were surfeited, the food was withheld till the appetite returned, when a small quantity was given, and increased gradually to the full allowance. but the most elaborate and valuable experiments in the feeding and management of milch cows, are those made, not long since, by mr. t. horsfall, of england, and published in the journal of the royal agricultural society. his practice, though adapted more especially, perhaps, to his own section, is nevertheless of such general application and importance as to be worthy of attention. by his course of treatment he found that he could produce as much and as rich butter in winter as in summer. his first object was to afford a full supply of the elements of food adapted to the maintenance, and also to the produce of the animal; and this could not be effected by the ordinary food and methods of feeding, since it is impossible to induce a cow to consume a quantity of hay requisite to supply the waste of the system, and keep up, at the same time, a full yield of the best quality of milk. he used, to some extent, cabbages, kohl rabi, mangolds, shorts, and other substances, rich in the constituents of cheese and butter. "my food for milch cows," says he, "after having undergone various modifications, has for two seasons consisted of rape cake five pounds, and bran two pounds, for each cow, mixed with a sufficient quantity of bean-straw, oat-straw, and shells of oats, in equal proportions, to supply them three times a day with as much as they will eat. the whole of the materials are moistened and blended together, and, after being well steamed, are given to the animal in a warm state. the attendant is allowed one pound to one pound and a half per cow, according to circumstances, of bean-meal, which he is charged to give to each cow in proportion to the yield of milk; those in full milk getting each two pounds per day, others but little. it is dry, and mixed with the steamed food on its being dealt out separately. when this is eaten up, green food is given, consisting of cabbages, from october to december, kohl rabi till february, and mangold till grass time, with a view to nicety of flavor. i limit the quantity of green food to thirty or thirty-five pounds per day for each. after each feed, four pounds of meadow hay, or twelve pounds per day, is given to each cow. they are allowed water twice a day, to the extent which they will drink." bean-straw uncooked having been found to be hard and unpalatable, it was steamed to make it soft and pulpy, when it possessed an agreeable odor, and imparted its flavor to the whole mass. it was cut for this purpose just before ripening, but after the bean was fully grown, and in this state was found to possess nearly double the amount of albuminous matter, so valuable to milch cows, of good meadow or upland hay. bran or shorts is also vastly improved by steaming or soaking with hot water, when its nutriment is more readily assimilated. it contains about fourteen per cent. of albumen, and is rich in phosphoric acid. rape-cake was found to be exceedingly valuable. linseed and cotton-seed cake may probably be substituted for it in this country. mr. horsfall turned his cows in may into a rich pasture, housing them at night, and giving them a mess of the steamed mixture and some hay morning and night; and from june to october they had cut grass in the stall, besides what they got in the pasture, and two feeds of the steamed mixture a day. after the beginning of october the cows were kept housed. with such management his cows generally yielded from twelve to sixteen quarts of milk (wine measure) a day, for about eight months after calving, when they fell off in milk, but gained in flesh, up to calving-time. in this course of treatment the manure was far better than the average, and his pastures constantly improved. the average amount of butter from every sixteen quarts of milk was twenty-five ounces--a proportion far larger than the average. [illustration: "on the rampage."] how widely does this course of treatment differ from that of most farmers! the object with many seems to be, to see with how little food they can keep the cow alive. from a correct point of view, the milch cow should be regarded as an instrument of transformation. the question should be--with so much hay, so much grain, so many roots, how can the most milk, or butter, or cheese, be made? the conduct of a manufacturer who owned good machinery, and an abundance of raw material, and had the labor at hand, would be considered very senseless, if he hesitated to supply the material, and keep the machinery at work, at least so long as he could run it with profit. stimulate the appetite, then, and induce the cow to eat, by a frequent change of diet, not merely enough to supply the constant waste of her system, but enough and to spare, of a food adapted to the production of milk of the quality desired. soiling. of the advantages of soiling milch cows--that is, feeding exclusively in the barn--there are yet many conflicting opinions. as to its economy of land and feed there can be no question, it being generally admitted that a given number of animals may be abundantly fed on a less space; nor is there much question as to the increased quantity of milk yielded in stall feeding. its economy, in this country, turns rather upon the cost of labor and time; and the question raised by the dairyman is, whether it will pay--whether its advantages are sufficient to balance the extra expense of cutting and feeding, over and above cropping on the pasture. the importance of this subject has been strongly impressed upon the attention of farmers in many sections of the country, by a growing conviction that something must be done to improve the pastures, or that they must be abandoned altogether. thousands of acres of neglected pasture-land in the older states are so poor and worn out that from four to eight acres furnish but a miserable subsistence for a good-sized cow. no animal can flourish under such circumstances. the labor and exertion of feeding are too great, to say nothing of the vastly inferior quality of the grasses in such pastures, compared with those on more recently seeded lands. true economy would dictate that such pastures should either be allowed to run to wood, or be devoted to sheep-walks, or ploughed and improved. cows, to be able to yield well, must have plenty of food of a sweet and nutritious quality; and, unless they find it, they wander over a large space, if at liberty, and thus deprive themselves of rest. if a farmer or dairyman unfortunately owns such pastures, there can be no question that, as a matter of real economy, he had better resort to the soiling system for his milch cows; by which means he will largely increase his annual supply of good manure, and thus have the means of improving, and bringing his land to a higher state of cultivation. a very successful instance of this management occurs in the report of the visiting committee of an agricultural society in massachusetts, in which they say: "we have now in mind a farmer in this county who keeps seven or eight cows in the stable through the summer, and feeds them on green fodder, chiefly indian corn. we asked him his reasons for it. his answer was: 1. that he gets more milk than he can by any other method. 2. that he gets more manure, especially liquid manure. 3. that he saves it all, by keeping a supply of mud or mould under the stable, to be taken out and renewed as often as necessary. 4. that it is less troublesome than to drive his cows to pasture; that they are less vexed by flies, and have equally good health. 5. that his mowing land is every year growing more productive, without the expense of artificial manure.--he estimates that on an acre of good land twenty tons of green fodder may be raised. that which is dried is cut fine, and mixed with meal or shorts, and fed with profit. he believes that a reduced and worn-out farm--supposing the land to be naturally good--could be brought into prime order in five years, without any extra outlay of money for manure, by the use of green fodder in connection with the raising and keeping of pigs; not fattening them, but selling at the age of four or five months." he keeps most of his land in grass, improving its quality and productiveness by means of top-dressing, and putting money in his pocket--which is, after all, the true test both for theory and practice. another practical case on this point is that of a gentleman in the same state who had four cows, but not a rod of land on which to pasture them. they were, therefore, never out of the barn--or, at least, not out of the yard--and were fed with grass, regularly mown for them; with green indian corn and fodder, which had been sown broadcast for the purpose; and with about three pints of meal a day. their produce in butter was kept for thirteen weeks. two of them were but two years old, having calved the same spring. all the milk of one of them was taken by her calf for six weeks out of the thirteen, and some of the milk of the other was taken for family use, the quantity of which was not measured. these heifers could not, therefore, be estimated as equal to more than one cow in full milk. and yet from these cows no less than three hundred and eighty-nine pounds of butter were made in the thirteen weeks. another pound would have made an average of thirty pounds a week for the whole time. it appears from these and other similar instances of soiling, or stall-feeding in summer on green crops cut for the purpose, that the largely increased quantity of the yield fully compensates for the slightly deteriorated quality. and not only is the quantity yielded by each cow increased, but the same extent of land, under the same culture, will carry double or treble the number of ordinary pastures, and keep them in better condition. there is also a saving of manure. but with us the economy of soiling is the exception, and not the rule. in adopting this system of feeding, regularity is required as much as in any other, and a proper variety of food. a succession of green crops should be provided, as near as convenient to the stable. the first will naturally be winter rye, in the northern states, as that shoots up with great luxuriance. winter rape would probably be an exceedingly valuable addition to the plants usually cultivated for soiling in this country, in sections where it would withstand the severity of the winter. cabbages, kept in the cellar or pit, and transplanted early, will also come in here to advantage, and clover will very soon follow them; oats, millet, and green indian-corn, as the season advances; and, a little later still, perhaps, the chinese sugar-cane, which should not be cut till headed out. these plants, in addition to other cultivated grasses, will furnish an unfailing succession of succulent and tender fodder; while the addition of a little indian, linseed, or cotton-seed meal will be found economical. in the vicinity of large towns and cities, where the object is too often to feed for the largest quantity, without reference to quality, an article known as distillers' swill, or still-slop, is extensively used. this, if properly fed in limited quantities, in combination with other and more bulky food, may be a valuable article for the dairyman; but, if given--as it too often is--without the addition of other kinds of food, it soon affects the health and constitution of the animals fed on it. this swill contains a considerable quantity of water, some nitrogenous compounds, and some inorganic matter in the shape of phosphates and alkaline salts found in the different kinds of grain of which it is made up, as indian corn, wheat, barley, rye, and the like. where this forms the principal food of milch cows, the milk is of a very poor quality--blue in color, and requiring the addition of coloring substances to make it saleable. it contains, often, less than one per cent. of butter, and seldom over one and three-tenths or one and a half per cent.--while good, saleable milk should contain from three to five per cent. it will not coagulate, it is said, in less than five or six hours; while good milk will invariably coagulate in an hour or less, under the same conditions. its effect on the system of young children is, therefore, very destructive, causing diseases of various kinds, and, if continued, death. so pernicious have been the consequences resulting from the use of this "swill-milk," as it is called, in the largest city of this country, that the legislature of the state of new york, at a recent session (1861-2), interfered in behalf of the community by making the sale of the article a penal offence. culture of grasses for fodder. as has been already stated, the grasses in summer, and hay in winter, form the most natural and important food for milch cows; and, whatever other crops come in as additional, these will form the basis of all systems of feeding. the nutritive qualities of the grasses differ widely; and their value as feed for cows will depend, to a considerable extent, on the management of pastures and mowing-lands. some considerations bearing upon the subject of the proper cultivation of these leading articles of food are, therefore, proposed in this article. [illustration: patiently waiting.] if the turf of an old pasture is carefully examined, it will be found to contain a large variety of plants and grasses adapted for forage; some of them valuable for one purpose, and some for another. some of them, though possessing a lower percentage of nutritive constituents than others, are particularly esteemed for an early and luxuriant growth, furnishing sweet feed in early spring, before other grasses appear; some of them, for starting more rapidly than others, after having been eaten off by cattle, and, consequently, of great value as pasture grasses. most grasses will be found to be of a social character, and do best in a large mixture with other varieties. in forming a mixture for pasture grasses, the peculiar qualities of each species should, therefore, be regarded: as the time of flowering, the habits of growth, the soil and location on which it grows best, and other characteristics. among the grasses found on cultivated lands in this country, the following are considered as among the most valuable for ordinary farm cultivation; some of them being adapted to pastures, and others almost exclusively to mowing and the hay-crop: timothy, meadow foxtail, june or kentucky blue grass, fowl meadow, rough-stalked meadow, orchard grass, perennial rye grass, italian rye grass, redtop, english bent, meadow fescue, tall oat grass, sweet-scented vernal, hungarian grass, red clover, white or dutch clover, and some others. of these, the most valuable, all things considered, is timothy. it forms a large proportion of what is commonly called english, or in some sections meadow, hay, though it originated and was first cultivated in this country. it contains a large percentage of nutritive matter, in comparison with other agricultural grasses. it thrives best on moist, peaty, or loamy soils, of medium tenacity, and is not well suited to very light, sandy lands. on very moist soils, its root is almost always fibrous; while on dry and loamy ones it is bulbous. on soils of the former description, which it especially affects, its growth is rapid, and its yield of hay large, sometimes amounting to three or four tons the acre, depending much, of course, upon cultivation. but, though very valuable for hay, it is not adapted for pasture, as it will neither endure severe grazing, nor is its aftermath to be compared with that of meadow foxtail, and some of the other grasses. june grass, better known in some sections as kentucky blue grass, is very common in most sections of the country, especially on limestone lands, forming a large part of the turf, wherever it flourishes, and being held in universal esteem as a pasture grass. it starts early, but varies much in size and appearance, according to the soil; growing in some places with the utmost luxuriance, and forming the predominant grass; in others, yielding to the other species. if cut at the time of flowering, or a few days after, it makes a good and nutritious hay, though it is surpassed in nutritive qualities by several of the other grasses. it starts slowly after having been cut, especially if not cut very early. but its herbage is fine and uniform, and admirably adapted to lawns, growing well in almost all soils, though it does not endure very severe droughts. it withstands, however, the frosts of winter better than most other grasses. in kentucky--a section where it attains its highest perfection and luxuriance, ripening its seeds about the tenth of june--and in latitudes south of that, it sometimes continues green through the mild winters. it requires three or four years to become well set, after sowing, and it does not attain its highest yield as a pasture grass till the sod is even older than that. it is not, therefore, suited to alternate husbandry, where land usually remains in grass but two or three years before being ploughed up. in kentucky, it is sown any time in winter when the sun is on the ground, three or four quarts of seed being used to the acre. in spring the seeds germinate, when the sprouts are exceedingly fine and delicate. stock is not allowed on it the first year. the meadow foxtail is also an excellent pasture grass it somewhat resembles timothy, but is earlier, has a softer spike, and thrives on all soils except the dryest. its growth is rapid, and it is greatly relished by stock of all kinds. its stalks and leaves are too few and light for a field crop, and it shrinks too much in curing to be valuable for hay. it flourishes best in a rich, moist, and rather strong soil, sending up a luxuriant aftermath when cut or grazed off, which is much more valuable, both in quality and nutritive value, than the first crop. in all lands designed for permanent pasture, therefore, it should form a considerable part of a mixture. it will endure almost any amount of forcing, by liquid manures or irrigation. it requires three or four years, after soiling, to gain a firm footing in the soil. the seed is covered with the soft and woolly husks of the flower, and is consequently light; weighing but five pounds to the bushel, and containing seventy-six thousand seeds to the ounce. the orchard grass, or rough cocksfoot, for pastures, stands pre-eminent. this is a native of this country, and was introduced into england, from virginia, in 1764, since which time its cultivation has extended into every country of europe, where it is universally held in very high estimation. the fact of its being very palatable to stock of all kinds, its rapid growth, and the luxuriance of its aftermath, with its power of enduring the cropping of cattle, have given it a very high reputation, especially as a pasture grass. it blossoms earlier than timothy; when green, is equally relished by milch cows; requires to be fed closer, to prevent its forming tufts and growing up to seed, when it becomes hard and wiry, and loses much of its nutritive quality. as it blossoms about the same time, it forms an admirable mixture with red clover, either for permanent pasture or mowing. it resists drought, and is less exhausting to the soil than either rye grass or timothy. the seed weighs twelve pounds to the bushel, and when sown alone requires about two bushels to the acre. the rough-stalked meadow grass is somewhat less common than the june grass, but is considered equally valuable. it grows best on moist, sheltered meadows, where it flowers in june and july. it is readily distinguished from june grass by its having a rough sheath, while the latter has a smooth one, and by having a fibrous root, while the root of the other is creeping. it possesses very considerable nutritive qualities, and comes to perfection at a desirable time, and is exceedingly relished by cattle, horses and sheep. for suitable soils it should form a portion of a mixture of seeds, producing, in mixture with other grasses which serve to shelter it, a large yield of hay, far above the average of grass usually sown on a similar soil. it should be cut when the seed is formed. seven pounds of seed to the acre will make a good sward. the grass loses about seventy per cent. of its weight in drying. the nutritive qualities of its aftermath exceed very considerably those of the crop cut in the flower or in the seed. fowl meadow grass is another indigenous species, of great value for low and marshy grounds, where it flourishes best; and, if cut and properly cured, makes a sweet and nutritious hay, which, from its fineness, is eaten by cows without waste. according to sinclair--who experimented, with the aid of sir humphrey davy, to ascertain its comparative nutritive properties--it is superior in this respect to either meadow foxtail, orchard grass, or tall meadow oat grass; but it is probable that he somewhat overrates it. if allowed to stand till nearly ripe, it falls down, but sends up innumerable flowering stems from the joints, so that it continues green and luxuriant till late in the season. it thrives best in mixture with other grasses, and deserves a prominent place in all mixtures for rich, moist pastures, and low mowing-lands. rye grass has a far higher reputation abroad than in this country, and probably with reason; for it is better adapted to a wet and uncertain climate than to a dry and hot one. it varies exceedingly, depending much on soil and culture; but, when cut in the blossom to make into hay, it possesses very considerable nutritive power. if allowed to get too ripe, it is hard and wiry, and not relished by cows. the change from a juicy and nutritious plant to a woody fibre, containing but little soluble matter, is very rapid. properly managed, however, it is a tolerably good grass, though not to be compared to timothy, or orchard grass. redtop is a grass familiar to every farmer in the country. it is the herd's grass of pennsylvania, while in new york and new england it is known by a great variety of names and assumes a great variety of forms, according to the soil in which it grows. it is well adapted to almost every soil, though it seems to prefer a moist loam. it makes a profitable crop for spending, in the form of hay, though its yield is less than that of timothy. it is well suited to our permanent pastures, where it should be fed close, otherwise it becomes wiry and innutritious, and cattle refuse it. it stands the climate of the country as well as any other grass, and so forms a valuable part of any mixture for pastures and permanent mowing-lands; but it is, probably, rather over rated by us. english bent, known also by a number of other names, is largely cultivated in some sections. it closely resembles redtop, but may be distinguished from it by the roughness of the sheaths when the hand is drawn from above downward. it possesses about the same qualities as redtop. meadow fescue is one of the most common of the fescue grasses, and is said to be the randall grass of virginia. it is an excellent pasture grass, forming a very considerable portion of the turf of old pasture lands and fields; and is more extensively propagated and diffused from the fact that it ripens its seeds before most other grasses are cut, and sheds them to spring up and cover the ground. its long and tender leaves are much relished by cattle. it is rarely sown in this country, notwithstanding its great and acknowledged value as a pasture grass. if sown at all, it should be in mixture with other grasses, as orchard grass, and rye grass, or june grass. it is of much greater value at the time of flowering than when the seed is ripe. [illustration: a chance for a selection.] the tall oat grass is the ray grass of france. it furnishes a luxuriant supply of foliage, is valuable either for hay or for pasture, and has been especially recommended for soiling purposes, on account of its early and luxuriant growth. it is often found on the borders of fields and hedges, woods and pastures, and is sometimes very plenty in mowing-lands. after having been mown it shoots up a very thick aftermath, and, on this account, partly, is regarded of nearly equal excellence with the common foxtail. it grows spontaneously on deep, sandy soils, when once naturalized. it has been cultivated to a considerable extent in this country, and is esteemed by those who know it mainly for its early, rapid, and late growth, making it very well calculated as a permanent pasture grass. it will succeed on tenacious clover soil. the sweet-scented vernal grass is one of the earliest in spring and one of the latest in autumn; and this habit of growth is one of its chief excellencies, as it is neither a nutritious grass, nor very palatable to stock of any kind, nor does it yield a very good crop. it is very common in new england and all over the middle states, coming into old worn-out fields and moist pastures spontaneously, and along every roadside. it derives its name from its sweetness of odor when partially wilted or crushed in the hand, and it is this chiefly which gives the delicious fragrance to all new-mown bay. it is almost the only grass that possesses a strongly-marked aromatic odor, which is imparted to other grasses with which it is cured. its seed weighs eight pounds to the bushel. in mixtures for permanent pastures it may be of some value. hungarian grass, or millet, is an annual forage plant, introduced into france in 1815, and more recently into this country. it germinates readily, and withstands the drought remarkably, remaining green when other grasses are parched and dried up. it has numerous succulent leaves which furnish an abundance of sweet fodder, greatly relished by stock of all kinds. it attains its greatest luxuriance on soils of medium consistency and richness, but does very well on light and dry plains. red clover is an artificial grass of the leguminous family, and one of the most valuable cultivated plants for feeding to dairy cows. it flourishes best on tenacious soils and stiff loams. its growth is rapid, and a few months after sowing are sufficient to supply an abundant sweet and nutritious food. in the climate of new england, clover should be sown in the spring of the year, while most of the natural grasses do far better when sown in the fall. it is often sown with perfect success on the late snows of march or april, and soon finds its way down into the soil and takes a vigorous hold with its root. it is valuable not only as a forage plant, but as shading the ground, and thereby increasing its fertility. the introduction of clover among the cultivated plants of the farm has done more, perhaps, for modern agriculture than that of any other single plant. it is now considered indispensable in all good dairy districts. white clover, often called honeysuckle, is also widely diffused over this country, to which it is undoubtedly indigenous. as a mixture in all pasture grasses it holds a very high rank, as it is exceedingly sweet and nutritious, and relished by all kinds of stock. it grows most luxuriantly in moist grounds and moist seasons, but easily accommodates itself to a great variety of circumstances. with respect to the mixtures of grass-seeds most profitable for the dairy farmer, no universal rule can be given, as they depend very much upon the nature of the soil and the locality. the most important point to be observed, and the one as to which, probably, the greatest deficiency exists, is to use a large number of species, with smaller quantities of each than those most commonly used. this is nature's rule; for, in examining the turf of a rich old pasture, a large number of different species will be found growing together, while, if the turf of a field sown without two or three species is examined, a far less number of plants is found to the square foot, even after the sod is fairly set. in the opinion of the most competent judges, no improvement in grass culture is more important than this. as an instance of what he would consider an improvement on the ordinary mixtures for _permanent pastures_, mr. flint, in his "milch cows and dairy farming," suggests the following as likely to give satisfactory results, dependent, of course, to a considerable extent, on the nature and preparation of the soil: meadow foxtail, flowering in may and june, 2 pounds orchard grass, " " " " 6 " sweet-scented vernal, " " april and may, 1 " meadow fescue, " " may and june, 2 " redtop, " " june and july, 2 " june grass, " " may and june, 4 " italian rye grass, " " june, 4 " perennial do., " " " " 6 " timothy, " " june and july, 3 " rough-stalked meadow grass, " " 2 " perennial clover, flowering in june, 3 " white clover, " " may to september 5-40 " for mowing-lands the mixture would, of course, be somewhat changed. the meadow foxtail and sweet-scented vernal would be left out entirely, and some six or eight pounds added to the timothy and red clover. the proper time to lay down lands to grass in the latitude of new england is august or september, and no grain crop should be sown with the seed. stiff or clayey pastures should never be overstocked, but when fed pretty close the grasses are far sweeter and more nutritious than when they are allowed to grow up rank and coarse; and if, by a want of sufficient feeding, they get the start of the stock, and grow into rank tufts, they should be cut and removed, when a fresh grass will start up, similar to the aftermath of mowing-lands, which will be eaten with avidity. grasses for curing into hay should be cut either at the time of flowering, or just before, especially if designed for milch cows. they are then more succulent and juicy, and, if properly cured, form the sweetest food. grass cut in the blossom will make more milk than if allowed to stand later. cut a little before the blossoming; it will make more than when in blossom, and the cows prefer it, which is by no means an unimportant consideration, since their tastes should always be consulted. grass cut somewhat green, and properly cured, is next to fresh, green grass in palatable, nutritive qualities. every farmer knows the milk-producing properties of rowen, or second crop, which is generally cut before it ripens. no operation on the farm is of greater importance to the dairyman than the cutting of his grass and the manner of curing hay; and in this respect the practice over the country generally is susceptible of very marked improvement. the chief object is to preserve the sweetness and succulence of the grass in its natural state, so far as possible; and this object cannot be attained by exposing it too long to the scorching suns and drenching rains to which our climate is liable. as a general thing, farmers try to make their hay too much. as to the best modes of curing clover, the following, among others, is adopted by many successful farmers: what is mown in the morning is left in the swath, to be turned over early in the afternoon. at about four o'clock, or while it is still warm, it is put into small cocks with a fork, and, if the weather is favorable, it may be housed on the fourth or fifth day, the cocks being turned over on the morning of the day in which it is to be carted. by this method all the heads and leaves are saved, and these are more valuable than the stems. for new milch cows in winter scarcely any food is better. it will cause them to give as great a flow of milk as any hay, unless it be good rowen. indian corn makes an exceedingly valuable fodder, both as a means of carrying a herd of milch cows through our severe droughts of summer, and as an article for soiling cows kept in the stall. no dairy farmer will neglect to sow an extent in proportion to the number of cows which he keeps. the most common practice is, to sow in drills from two and a half to three feet apart, on land well tilled and thoroughly manured, making the drills from six to ten inches wide with the plough, manuring in the furrow, dropping the kernels about two inches apart, and covering with the hoe. in this mode of culture, the cultivator may be used between the rows when the corn is from six to twelve inches high, and, unless the ground is very weedy, no other after culture is needed. the first sowing usually takes place about the middle of may, and this is succeeded by other sowings, at intervals of a week or ten days, till july, in order to have a succession of green fodder; but, if it is designed to cut it up to cure for winter use, an early sowing is generally preferred, in order to be able to cure it in warm weather, in august or early in september. sown in this way, about three or four bushels of corn are required for an acre; since, if sown thickly, the fodder is better, the stalks smaller, and the waste less. the chief difficulty in curing corn cultivated for this purpose, and after the methods just spoken of, arises from the fact that it comes at a season when the weather is often colder, the days shorter, and the dews heavier, than when the curing of hay takes place. nor is the curing of corn cut up green so easy and simple as that of the drying of stalks of indian corn cut above the ear, as in the common practice of topping. the plant is then riper, less juicy, and cures more readily. the method sometimes adopted is to cut and tie into small bundles, after it is somewhat wilted, and then to stook upon the ground, where it is allowed to stand, subject to all the changes of weather, with only the protection of the stook itself. the stooks consist of bunches of stalks first bound into small bundles, and are made sufficiently large to prevent the wind from blowing them over. the arms are thrown around the tops to bring them as closely together as possible, when the tops are broken over or twisted together, or otherwise fastened, in order to make the stook "shed the rain" as well as possible. in this condition they remain out until they are sufficiently dried to be put in the barn. corn fodder is very excellent for young dairy stock. common millet is another very valuable crop for fodder in soiling, or to cure for winter use, but especially to feed out during the usual season of drought. many varieties of millet are cultivated in this country, the ground being prepared and treated as for oats. if designed to cut for green fodder, half a bushel of seed to the acre should be used; if to ripen seed, twelve quarts, sown broadcast, about the last of may or early in june. a moist loam or muck is the best soil adapted to millet; but very great crops have been grown on dry upland. it is very palatable and nutritious for milch cows, both green and when properly cured. the curing should be very much like that of clover, care being taken not to over-dry it. for fodder, either green or cured, it is cut before ripening. in this state all cattle eat it as readily as green corn, and a less extent will feed them. millet is worthy of a widely-extended cultivation, particularly on dairy farms. indian millet is another cultivated variety. rye, as a fodder plant, is chiefly valuable for its early growth in spring. it is usually sown in september or october--from the middle to the end of september being, perhaps, the most desirable time--on land previously cultivated and in good condition. if designed to ripen only, a bushel of seed is required to the acre, evenly sown; but, if intended for early fodder in spring, two or two and a half bushels of seed per acre should be used. on warm land the rye can be cut green the last of april or the first of may. care should be taken to cut early; since, if it is allowed to advance too far towards maturity, the stalk becomes hard and unpalatable to cows. oats are also sometimes used for soiling, or for feeding green, to eke out a scanty supply of pasture feed; and for this purpose they are valuable. they should be sown on well-tilled and well-manured land, about four bushels to the acre, towards the last of april or the first of may. if the whole crop is to be used as green fodder, five bushels of seed will not be too much for good, strong soil. they will be sufficiently grown to cut by the first of july, or in some sections earlier, depending upon the location. the chinese sugar-cane also may deserve attention as a fodder plant. experiments thus far made would seem to show that when properly cultivated, and cut at the right time, it is a palatable and nutritious plant, while many of the failures have been the result of too early cutting. for a fodder crop the drill culture is preferable, both on account of the larger yield obtained and because it is thus prevented from becoming too hard and stalky. of the root crops the potato is the first to be mentioned. this produces a large quantity of milk, though the quality is inferior. the market value of this root is, at times, too great to allow of feeding extensively with it, even in milk dairies, where it is most valuable as a food for cows; still, there are locations where it may be judicious to cultivate this root for dairy feed, and in all circumstances there is a certain portion of the crop of unmarketable size, which will be of value fed to milch cows or swine. it should be planted in april or may, but in many sections in june, on good mellow soil, first thoroughly plowed and harrowed, then furrowed three feet apart, and manured in the furrows with a mixture of ashes, plaster of paris, and salt. the seed may be dropped in the furrows, one foot apart, after the drill system--or in hills, two and a half or three feet apart--to be covered with the plough by simply turning the furrows back, after which the whole should be rolled with the field-roller, when it can be done. if the land is not already in good heart from continued cultivation, a few loads of barnyard manure may be spread, and plowed under, by the first plowing. used in this way it is far less liable to cause the rot, than when it is put in the hill. if a sufficient quantity of wood-ashes is not at hand, sifted coal-ashes will answer the purpose, and these are said to be valuable as a preventive of rot. in this way, one man, two boys, and a horse can plant from three to four acres a day on mellow land. by another method two acres a day on the sod have been planted. the manure is first spread upon the grass, and then a furrow made by a yoke of oxen and one man, another following after and dropping, a foot apart, along the outer edge of the furrow on the grass. by quick work, one hand can nearly keep up with the plow in dropping. when arrived at the end of the piece, a back furrow is turned up to the potatoes, and a good plowman will cover nearly all without difficulty. on the return furrow, the man or boy who dropped follows after, covering up any that may be left or displaced, and smoothing off the top of the back-furrows when necessary. potatoes thus planted have come out finely. the cost of cultivation in this mode, it must be evident, is but trifling, compared with the slower method of hand-planting. it requires a skillful ploughman, a quick, active lad, and a good yoke of oxen, and the extent of the work will depend somewhat upon the state of the turf. the nutritive equivalent for potatoes in a hundred pounds of good hay is 319 pounds; that is, it will take 3.19 pounds of potatoes to afford the same amount of nourishment as one pound of hay. the great value of roots is as a change or condiment calculated to keep the animal in a healthy condition. [illustration: a west highland ox.] the carrot is somewhat extensively fed, and is a valuable root for milch cows. this, like the potato, has been cultivated and improved from a wild plant. carrots require a deep, warm, mellow soil, thoroughly cultivated, but clean, and free from weed-seed. the difference between a very good profit and a loss on the crop depends much upon the use of land and manures perfectly free from foul seeds of any kind. ashes, guano, seaweed, ground bones, and other similar substances, or thoroughly-rotted and fermented compost, will answer the purpose. after plowing deep, and harrowing carefully, the seed should be planted with a seed-sower, in drills about eighteen inches apart, at the rate of four pounds to the acre, about the middle of may. the difference between sowing on the fifteenth of may and on the tenth of june in new england is said to be nearly one-third in the crop on an average of years. in weeding, a little wheel hoe is invaluable, as with it a large part of the labor of cultivation is saved. a skillful hand can run this hoe within a half an inch of the young plants without injury, and go over a large space in the course of a day, if the land was properly prepared in the first place. the american farmer should always plan to economize labor, which is the great item of expense upon a farm. by this is not meant that he should strive to shirk or avoid work, but that he should make the least amount of work accomplish the greatest and most profitable results. labor-saving machinery on the farm is applied, not to reduce the number of hours of labor, or to make the owner a man of leisure--who is, generally, the unhappiest man in the world--but to enable him to accomplish the greatest results in the same time that he would be compelled to obtain smaller ones. carrots will continue to grow and increase in size late into the fall. when ready to dig, plow around as near to the outside rows as possible, turning away the furrow from the row. then take out the carrots, pulling off the tops, and throw the carrots and tops into separate heaps on the plowed furrows. in this way a man and two boys can harvest and put into the cellar upwards of a hundred bushels a day. the turnip, and the swedish turnip, or ruta baga, are also largely cultivated as a field crop to feed to stock; and for this purpose almost numberless varieties are used, furnishing a great amount of succulent and nutritious food, late into winter, and, if well-kept, late into spring. the chief objection to the turnip is, that it taints the milk. this may be remedied--to a considerable extent, if not wholly--by the use of salt, or salt hay, and by feeding at the time of milking, or immediately after, or by steaming before feeding, or putting a small quantity of the solution of nitre into the pail, and milking upon it. turnips may be sown any time in june, in rich land, well mellowed by cultivation. very large crops are obtained, sown as late as the middle of july, or the first of august, on an inverted sod. the michigan, or double-mould-board plow leaves the land light, and in admirable condition to harrow, and drill in turnips. in one instance, a successful root-grower cut two tons of hay to the acre, on the twenty-third of june, and after it was removed from the land spread eight cords of rotten kelp to the acre, and plowed in; after which about three cords of fine old compost manure were used to the acre, which was sown with ruta baga seed, in drills, three feet apart, plants thinned to eight or ten inches in the drill. no after cultivation was required. on the fifteenth of november he harvested three hundred and seventy bushels of splendid roots to the acre, carefully measured off. the nutritive equivalent of swedish turnips as compared with good meadow hay is 676, taking hay as a standard at 100; that is, it would require 6.76 pounds of turnips to furnish the same nutriment as one pound of good hay; but fed in connection with other food--as hay, for example--perhaps five pounds of turnips would be about equal to one pound of hay. the english or round turnip is usually sown broadcast after some other crop, and large and valuable returns are often obtained. the swede is sown in drills. both of these varieties are used for the production of milk. the chief objection to the turnip crop is that it leaves many kinds of soil unfit for a succession of some other crops, like indian corn, for instance. in some sections, no amount of manuring appears to make corn do well after turnips or ruta bagas. the mangold wurtzel, a variety of the common beet, is often cultivated in this country with great success, and fed to cows with advantage, furnishing a succulent and nutritive food in winter and spring. the crop is somewhat uncertain. when it does well, an enormous yield is often obtained; but, not rarely, it proves a failure, and is not, on the whole, quite as reliable as the ruta baga, though a more valuable crop when the yield is good. it is cultivated like the common beet in moist, rich soils; three pounds of seed to the acre the leaves may be stripped off, towards fall, and fed out, without injury to the growth of the root. both mangolds and turnips should be cut with a root-cutter, before being fed out. the parsnip is a very sweet and nutritious article of fodder, and adds richness and flavor to the milk. it is worthy of extended culture in all parts of the country where dairy husbandry is pursued. it is a biennial, easily raised on deep, rich, well-cultivated and well-manured soils, often yielding enormous crops, and possessing the decided advantage of withstanding the severest winters. as an article of spring feeding, therefore, it is exceedingly valuable. sown in april or may, it attains a large growth before winter. then, if desirable, a part of the crop may be harvested for winter use, and the remainder left in the ground till the frost is out, in march or april, when they can be dug as wanted, and are exceedingly relished by milch cows and stock of all kinds. they make an admirable feed at the time of milking, and produce the richest cream, and the yellowest and finest-flavored butter, of any roots used among us. the best dairy farmers on the island of jersey often feed to their cows from thirty to thirty-five pounds of parsnips a day, in addition to hay or grass. both practical experiment and scientific analysis prove this root to be eminently adapted to dairy stock, where the richness of milk or fine-flavored butter is any object. for mere milk-dairies, it is not quite so valuable, probably, as the swedish turnip. the culture is similar to that of carrots, a rich, mellow, and deep loam being best; while it has a great advantage over the carrot in being more hardy, and rather less liable to injury from insects, and more nutritive. for feeding and fattening stock it is eminently adapted. to be sure of a crop, fresh seed must be had, as it cannot be depended on for more than one year. for this reason the largest and straightest roots should be allowed to stand for seed, which, as soon as nearly ripe, should be taken out and spread out to dry, and carefully kept for use. for field culture, the hollow-crowned parsnip is the best and most profitable; but on thin, shallow soils the turnip-rooted variety should be used. parsnips may be harvested like carrots, by plowing along the rows. let butter or cheese dairymen give this crop a fair and full trial, and watch its effect in the quality of the milk and butter. the kohl rabi is also cultivated to a considerable extent in this country for the purpose of feeding stock. it is supposed to be a hybrid between the cabbage and the turnip and is often called the cabbage-turnip, having the root of the former, with a turnip-like or bulbous stem. the special reason for its more extensive cultivation among us is its wonderful indifference to droughts, in which it seems to flourish best, and to bring forth the most luxuriant crops. it also withstands the frosts remarkably, being a hardy plant. it yields a somewhat richer quality of milk than the ordinary turnip, and the crop is generally admitted to be as abundant and profitable. very large crops of it have been produced by the ordinary turnip or cabbage cultivation. as in cabbage-culture, it is best to sow the seed in march or april, in a warm and well-enriched seed-bed; from which it is transplanted in may, and set out after the manner of cabbages in garden culture. it bears transplanting better than most other roots. insects injure it less than the turnip, dry weather favors it, and it keeps well through winter. for these reasons, it must be regarded as a valuable addition to our list of forage plants adapted to dairy farming. it grows well on stronger soils than the turnip requires. linseed meal is the ground cake of flaxseed after the oil is pressed out. it is very rich in fat-forming principles, and given to milch cows increases the quality of butter, and keeps them in condition. four or five pounds a day are sufficient for cows in milk, and this amount will effect a great saving in the cost of other food, and at the same time make a very rich milk. it is extensively manufactured in this country, and largely exported, but it is worthy of more general use here. it must not be fed in too large quantities to milch cows, for it would be liable to give too great a tendency to fat, and thus affect the quantity of the milk. cotton-seed meal is an article of comparatively recent introduction. it is obtained by pressing the seed of the cotton-plant, which extracts the oil, when the cake is crushed or ground into meal, which has been found to be a very valuable article for feeding stock. from analysis it is shown to be equal or superior to linseed meal. practical experiments only are needed to establish it. it can be procured in market at a reasonable price. the manures used in this country for the culture of the above named plants are mostly such as are made on the farm, consisting chiefly of barnyard composts of various kinds, with often a large admixture of peat-mud. there are few farms that do not contain substances, which, if properly husbanded, would add very greatly to the amount of manure ordinarily made. the best of the concentrated manures, which it is sometimes necessary to use, for want of time and labor to prepare enough upon the farm, is, unquestionably, peruvian guano. the results of this, when properly applied, are well known and reliable, which can hardly be said of any other artificial manure offered for the farmer's notice. the chief objection to depending upon manures made off the farm is, in the first place, their great expense; and in the second--which is equally important--the fact, that, though they may be made valuable, and produce at one time the best results, a want of care in the manufacture, or designed fraud, may make them almost worthless, with the impossibility of detecting the imposition, without a chemical analysis, till it becomes too late, and the crop is lost. it is, therefore, safest to rely mainly upon the home manufacture of manure. the extra expense of soiling cattle, saving and applying the liquid manure, and thus bringing the land to a higher state of cultivation, when it will be capable of keeping more stock and furnishing more manure, would offer a surer road to success than a constant outlay for concentrated fertilizers. the barn. the farm barn, next to the farm house, is the most important structure of the farm itself, in the northern and middle states; and even at the south and southwest, where barns are less used, they are of more importance in the economy of farm management than is generally understood. indeed, to the eyes of a person of taste, a farm or plantation appears incomplete, without good barn accommodations, as much as without good household appointments--and without them, no agricultural establishment can be complete in all its proper economy. the most _thorough_ barn structures, perhaps, to be seen in the united states, are those of the state of pennsylvania, built by the german farmers of the lower and central counties. they are large, and expensive in their construction; and, in a strictly economical point of view, are, perhaps, more costly than is required. yet, there is a substantial durability about them, that is exceedingly satisfactory, and, where the pecuniary ability of the farmer will admit, they may well furnish models for imitation. in the structure of the barn, and in its interior accommodation, much will depend upon the branches of agriculture to which the farm is devoted. a farm cultivated in grain chiefly requires but little room for stabling purposes. storage for grain in the sheaf, and granaries, will require its room; while a stock farm requires a barn with extensive hay storage, and stables for its cattle, horses, and sheep, in all climates which do not admit of such stocks living through the winter in the field, as is the case in the great grazing districts west of the alleghanies. again, there are wide districts of country where a mixed husbandry of grain and stock is pursued, which require barns and outbuildings accommodating both. it may be well here to remark that many designers of barns, sheds, and other outbuildings for the accommodation of farm stock, have indulged in fanciful arrangements for the comfort and convenience of animals, which are so complicated that when constructed, as they sometimes are, the practical, common-sense farmer will not use them; and by reason of the learning which is required for their use, they are altogether unsuitable for the treatment and use which they generally receive from those who have the daily care of the stock for which they are intended, and for the rough usage which they experience from the animals themselves. a very pretty and plausible arrangement of stabling, feeding, and all the other requirements of a barn establishment may be thus got up by an ingenious theorist at the fireside, which will work charmingly as he dilates upon its good qualities, untried; but, which, when subjected to experiment, will be utterly worthless for practical use. there can be no doubt that the simplest plan of construction, consistent with an economical expenditure of the material of food for the consumption of stock, is by far the most preferable. another item to be considered in this connection, is the comparative value of the stock, the forage fed to them, and the labor expended in feeding and taking care of them. to illustrate: suppose a farm to lie in the vicinity of a large town or city. its value is, perhaps, a hundred dollars an acre. the hay cut upon it is worth fifteen dollars a ton, at the barn, and straw and coarse grains in proportion, and hired labor ten or twelve dollars a month. consequently, the manager of this farm should use all the economy in his power, by the aid of cutting-boxes and other machinery, to make the least amount of forage supply the wants of his stock; and the internal economy of his barn should be arranged accordingly, since labor is his cheapest item, and food his dearest. therefore, any contrivance by which to work up his forage the closest--by way of machinery, or manual labor--so that it shall serve the purposes of keeping his stock, is true economy; and the making and saving of manures are items of the first importance. his buildings and their arrangements throughout should, for these reasons, be constructed in accordance with his practice. if, on the other hand, lands are cheap and productive, and labor comparatively dear, a different practice will prevail. the farmer will feed his hay from the mow without cutting. the straw will be stacked out, and the cattle turned to it, to pick what they like of it, and make their beds of the remainder; or, if it is housed, he will throw it into racks, and the stock may eat what they choose. to do this requires but one-third, or one-half of the labor which is required by the other mode, and the saving in this makes up, and perhaps more than makes up, for the increased quantity of forage consumed. again, climate may equally affect the mode of winter-feeding the stock. the winters may be mild. the hay may be stacked in the fields when gathered, or put into small barns built for hay storage alone; and the manure, scattered over the fields by the cattle, as they are fed from either of them, may be knocked to pieces with the dung-beetle, in the spring, or harrowed and bushed over the ground; and with the very small quantity of labor required in all this, such practice will be more economical than any other which can be adopted. in latitudes, however, in which it becomes necessary to stall-feed during several months of the year, barns are indispensable. these should be warm, and at the same time well ventilated. the barn should be arranged in a manner suitable to keeping hay and other fodder dry and sweet, and with reference to the comfort and health of the animals, and the economy of labor and manure. the size and finish will, of course, depend on the wants and means of the farmer or dairyman; but many little conveniences, it should not be forgotten, can be added at comparatively trifling cost. the accompanying cut of a barn is given merely as an illustration of a convenient arrangement for a medium-sized dairy, and not as being adapted to all circumstances or situations. this barn is supposed to stand upon a side-hill or an inclined surface, where it is easy to have a cellar, if desired; and the cattle-room, as shown in the cut, is in the second story, or directly over the cellar, the bottom of which should be somewhat dished, or lower in the middle than around the outer sides, and carefully paved, or laid in cement. [illustration: barn for thirty-four cows and three yoke of oxen.] on the outside is represented an open shed, _m_, for carts and wagons to remain under cover, thirty feet by fifteen, while _l l l l l l_ are bins for vegetables, to be filled through scuttles from the floor of the story above, and surrounded by solid walls. the area of this whole floor equals one hundred feet by fifty-seven. _k_, is an open space, nearly on a level with the cow-chamber, through the door _p_. _s_, stairs to the third story and to the cellar, _d d d_, passage next to the walls, five feet wide, and nine inches above the dung-pit. _e e e_, dung-pit, two feet wide, and seven inches below the floor where the cattle stand. the manure drops from this pit into the cellar below, five feet from the walls, and quite around the cellar. _c c c_, plank floor for cows, four feet six inches long. _b b b_, stalls for three yoke of oxen, on a platform five feet six inches long, _n n_, calf-pens, which may also be used for cows in calving. _r r_, feeding-troughs for calves. the feeding-boxes are made in the form of trays, with partitions between them. water comes in by a pipe, to cistern _a_. this cistern is regulated by a cock and ball, and the water flows by dotted lines, _o o o_, to the boxes; each box being connected by lead pipes well secured from frost, so that, if desired, each animal can be watered without leaving the stall, or water can be kept constantly before it. a scuttle, through which sweepings and refuse may be put into the cellar, is seen at _f_. _g_ is a bin receiving cut hay from the third story, or hay-room, _h h h h h h_, bins for grain-feed. _i_ is a tunnel to conduct manure or muck from the hay-floor to the cellar. _j j_, sliding-doors on wheels. the cows all face toward the open area in the centre. this cow-room may be furnished with a thermometer, clock, etc., and should always be well ventilated by sliding windows, which at the same time admit the light. the next cut is a transverse section of the same cow-room; _a_ being a walk behind the cows, five feet wide; _b_, dung-pit; _c_, cattle-stand; _d_, feeding-trough, with a bottom on a level with the platform where the cattle stand; _k_, open area, forty-three feet, by fifty-six. [illustration: transverse section.] the story above the cow-room--as represented in the next cut--is one hundred feet by forty-two; the bays for hay, ten on each side, being ten feet front and fifteen feet deep; and the open space, _p_, for the entrance of wagons, carts, etc., twelve feet wide. _b_, hay-scales. _c_, scale beam. _m m m m m m_, ladders reaching almost to the roof. _l l l_, etc., scuttle-holes for sending vegetables directly to the bins, _l l l_, etc., below. _a a b b_, rooms on the corners for storage. _d_, scuttles; four of which are used for straw, one for cut hay, and one for muck for the cellar. _n_ and the other small squares are eighteen-feet posts. _f_, passage to the tool-house, a room one hundred feet long by eighteen wide. _o_, stairs leading to the scaffold in the roof of the tool-house. _i i_, benches. _g_, floor. _h_, boxes for hoes, shovels, spades, picks, iron bars, old iron, etc. _j j j_, bins for fruit. _k_, scuttles to put apples into wagons, etc., in the shed below. one side of this tool-house may be used for plows and large implements, hay-rigging, harness, etc. proper ventilation of the cellar and the cow-room avoids the objection that the hay is liable to injury from noxious gases. [illustration: room over the cow-room.] the excellent manure-cellar beneath this barn extends only under the cow-room. it has a drive-way through doors on each side. no barn-cellar should be kept shut up tight, even in cold weather. the gases are constantly escaping from the manure, unless held by absorbents, which are liable not only to affect the health of the stock, but also to injure the quality of the hay. to prevent this, while securing the important advantages of a manure-cellar, the barn may be furnished with good-sized ventilators on the top, for every twenty-five feet of its length, and with wooden tubes leading from the cellar to the top. there should also be windows on different sides of the cellar to admit the free circulation of air. with these precautions, together with the use of absorbents in the shape of loam and muck, there will be no danger of rotting the timbers of the barn, or of risking the health of the cattle or the quality of the hay. the temperature at which the cow-room should be kept is somewhere from fifty to sixty degrees, fahrenheit. the practice and the opinions of successful dairymen differ somewhat on this point. too great heat would affect the health and appetite of the herd; while too low a temperature is equally objectionable, for various reasons. the most economical plan for room in tying cattle in their stalls, is to fasten the rope or chain, whichever is used--the wooden stanchion, or stanchel, as it is called, to open and shut, enclosing the animal by the neck, being objectionable--into a ring, which is secured by a strong staple into a post. this prevents the cattle from interfering with each other, while a partition effectually prevents any contact from the animals on each side of it, in the separate stalls. there is no greater benefit for cattle, after coming into winter-quarters, than a systematic regularity in every thing pertaining to them. every animal should have its own particular stall in the stable, where it should always be kept. the cattle should be fed and watered at certain fixed hours of the day, as near as may be. if let out of the stables for water, unless the weather is very pleasant--when they may be permitted to lie out for a short time--they should be immediately put back, and not allowed to range about with the outside cattle. they are more quiet and contented in their stables than elsewhere, and waste less food than if permitted to run out; besides being in every way more comfortable, if properly bedded and attended to, as every one will find upon trial. the habit which many farmers have, of turning their cattle out of the stables in the morning, in all weathers--letting them range about in a cold yard, hooking and annoying each other--is of no possible benefit, unless it be to rid them of the trouble of cleaning the stables, which pays more than twice its cost in the saving of manure. the outside cattle, which occupy the yard--if there are any--are all the better that the stabled ones do not interfere with them. they become habituated to their own quarters, as do the others, and all are better for being, respectively, in their proper places. milking. the manner of milking exerts a more powerful and lasting influence on the productiveness of the cow than most farmers are aware. that a slow and careless milker soon dries up the best of cows, every practical farmer and dairyman knows; but a careful examination of the beautiful structure of the udder will serve further to explain the proper mode of milking, in order to obtain and keep up the largest yield. the udder of a cow consists of four glands, disconnected from each other, but all contained within one bag or cellular membrane; and these glands are uniform in structure. each gland consists of three parts: the _glandular_, or secreting part, _tubular_ or conducting part, and the _teats_, or receptacle, or receiving part. the glandular forms by far the largest portion of the udder. it appears to the naked eye composed of a mass of yellowish grains; but under the microscope these grains are found to consist entirely of minute blood-vessels forming a compact plexus, or fold. these vessels secrete the milk from the blood. the milk is abstracted from the blood in the glandular part; the tubes receive and deposit it in the reservoir, or receptacle; and the sphincter at the end of the teat retains it there until it is wanted for use. this must not be understood, however, as asserting that all the milk drawn from the udder at one milking is contained in the receptacle. the milk, as it is secreted, is conveyed to the receptacle, and when that is full, the larger tubes begin to be filled, and next the smaller ones, until the whole become gorged. when this takes place, the secretion of the milk ceases, and absorption of the thinner or more watery part commences. now, as this absorption takes place more readily in the smaller or more distant tubes, it is invariably found that the milk from these, which comes last into the receptacle, is much thicker and richer than what was first drawn off. this milk has been significantly styled afterings, or strippings; and should this gorged state of the tubes be permitted to continue beyond a certain time, serious mischief will sometimes occur; the milk becomes too thick to flow through the tubes, and soon produces, first irritation, then inflammation, and lastly suppuration, and the function of the gland is materially impaired or altogether destroyed. hence the great importance of emptying these smaller tubes regularly and thoroughly, not merely to prevent the occurrence of disease, but actually to increase the quantity of milk; for, so long as the smaller tubes are kept free, milk is constantly forming; but whenever, as has already been mentioned, they become gorged, the secretion of milk ceases until they are emptied. the cow herself has no power over the sphincter at the end of her teat, so as to open it, and relieve the overcharged udder; neither has she any power of retaining the milk collected in the reservoirs when the spasm of the sphincter is overcome. thus is seen the necessity of drawing away the last drop of milk at every milking; and the better milker the cow, the more necessary this is. what has been said demonstrates, also, the impropriety of holding the milk in cows until the udder is distended much beyond its ordinary size, for the sake of showing its capacity for holding milk--a device to which many dealers in cows resort. thus much of the internal structure of the udder. its external form requires attention, because it indicates different properties. its form should be spheroidal, large, giving an idea of capaciousness; the bag should have a soft, fine skin, and the hind part upward toward the tail be loose and elastic. there should be fine, long hairs scattered plentifully over the surface, to keep it warm. the teats should not seem to be contracted, or funnel-shaped, at the inset with the bag. in the former state, teats are very apt to become corded, or spindled; and in the latter, too much milk will constantly be pressing on the lower tubes, or receptacle. they should drop naturally from the lower parts of the bag, being neither too short, small, or dumpy, or long, flabby, and thick, but, perhaps, about three inches in length, and so thick as just to fill the hand. they should hang as if all the quarters of the udder were equal in size, the front quarters projecting a little forward, and the hind ones a little more dependent. each quarter should contain about equal quantities of milk; though, in the belief of some, the hind quarters contain rather the most. largely developed milk-veins--as the subcutaneous veins along the under part of the abdomen are commonly called--are regarded as a source of milk. this is a popular error, for the milk-vein has no connection with the udder; yet, although the office of these is to convey the blood from the fore part of the chest and sides to the inguinal vein, yet a large milk-vein certainly indicates a strongly developed vascular system--one favorable to secretions generally, and to that of the milk among the rest. milking is performed in two ways, stripping and handling. _stripping_ consists in seizing the teat firmly near the root between the face of the thumb and the side of the fore-finger, the length of the teat passing through the other fingers, and in milking the hand passes down the entire length of the teat, causing the milk to flow out of its point in a forcible stream. the action is renewed by again quickly elevating the hand to the root of the teat. both hands are employed at the operation, each having hold of a different teat, and being moved alternately. the two nearest teats are commonly first milked, and then the two farthest. _handling_ is done by grasping the teat at its root with the fore-finger like a hoop, assisted by the thumb, which lies horizontally over the fore-finger, the rest being also seized by the other fingers. milk is drawn by pressing upon the entire length of the teat in alternate jerks with the entire palm of the hand. both hands being thus employed, are made to press alternately, but so quickly following each other that the alternate streams of milk sound to the ear like one forcible, continued stream. this continued stream is also produced by stripping. stripping, then, is performed by pressing and passing certain fingers along the teat; handling, by the whole hand doubled, or fist, pressing the teat steadily at one place. hence the origin of both names. [illustration: the preferable method.] of these two modes, handling is the preferable, since it is the more natural method--imitating, as it does, the suckling of the calf. when a calf takes a teat into its mouth, it makes the tongue and palate by which it seizes it, play upon the teat by alternate pressures or pulsations, while retaining the teat in the same position. it is thus obvious that handling is somewhat like sucking, whereas stripping is not at all like it. it is said that stripping is good for agitating the udder, the agitation of which is conducive to the withdrawal of a large quantity of milk; but there is nothing to prevent the agitation of the udder as much as the dairymaid pleases, while holding in the other mode. indeed, a more constant vibration could be kept up in that way by the vibrations of the arms than by stripping. stripping, by using an unconstrained pressure on two sides of the teat, is much more apt to press it unequally, than by grasping the whole teat in the palm of the hand; while the friction occasioned by passing the finger and thumb firmly over the outside of the teat, is more likely to cause heat and irritation in it than a steady and full grasp of the entire hand. to show that this friction causes an unpleasant feeling even to the dairymaid, she is obliged to lubricate the teat frequently with milk, and to wet it at first with water; whereas the other mode requires no such expedients. and as a further proof that stripping is a mode of milking which may give pain to the cow, it cannot be employed, when the teats are chapped, with so much ease to the cow as handling. the first requisite in the person that milks is, of course, the utmost _cleanliness_. without this, the milk is unendurable. the udder should, therefore, be carefully cleaned before the milking commences. milking should be done _fast_, to draw away the milk as quickly as possible, and it should be continued as long as there is a drop of milk to bring away. this is an issue which cannot be attended to in too particular a manner. if any milk is left, it is re-absorbed into the system, or else becomes caked, and diminishes the tendency to secrete a full quantity afterward. milking as dry as possible is especially necessary with young cows with their first calf; as the mode of milking and the length of time to which they can be made to hold out, will have very much to do with their milking qualities as long as they live. old milk left in the receptacle of the teat soon changes into a curdy state, and the caseous matter not being at once removed by the next milking, is apt to irritate the lining membrane of the teat during the operation, especially when the teat is forcibly rubbed down between the finger and thumb in stripping. the consequence of this repeated irritation is the thickening of the lining membrane, which at length becomes so hardened as to close up the orifice at the end of the teat. the hardened membrane may be easily felt from the outside of the teat, when the teat is said to be _corded_. after this the teat becomes _deaf_, as it is called, and no more milk can afterward be drawn from the quarter of the udder to which the corded teat is attached. the milking-pail is of various forms and of various materials. the dutch use brass ones, which are brilliantly scoured every time they are in use. tin pitchers are used in some places, while pails of wood in cooper-work are employed in others. a pail of oak, having thin staves bound together by bright iron hoops, with a handle formed by a stave projecting upward, is convenient for the purpose, and may be kept clean and sweet. one nine inches in diameter at the bottom, eleven inches at the top, and ten inches deep, with an upright handle or leg of five inches, has a capacious enough mouth to receive the milk as it descends; and a sufficient height, when standing on the edge of its bottom on the ground, to allow the dairymaid to grasp it firmly with her knees while sitting on a small three-legged stool. of course, such a pail cannot be milked full; but it should be large enough to contain all the milk which a single cow can give at a milking; because it is undesirable to rise from a cow before the milking is finished, or to exchange one dish for another while the milking is in progress. the cow being a sensitive and capricious creature, is, oftentimes so easily offended that if the maid rise from her before the milk is all withdrawn, the chances are that she will not again stand quietly at that milking; or, if the vessel used in milking is taken away and another substituted in its place, before the milking is finished, the probability is that she will _hold_ her milk--that is, not allow it to flow. this is a curious property which cows possess, of holding up or keeping back their milk. how it is effected has never been satisfactorily ascertained; but there is no doubt of the fact that when a cow becomes irritated, or frightened from any cause, she can withhold her milk. of course, all cows are not affected in the same degree; but, as a proof how sensitive cows generally are, it may be mentioned that very few will be milked so freely by a stranger the first time, as by one to whom they have been accustomed. there is one side of a cow which is usually called the _milking side_--that is the cow's left side--because, somehow custom has established the practice of milking her from that side. it may have been adopted for two reasons: one, because we are accustomed to approach all the larger domesticated animals by what we call the _near side_--that is, the animal's left side--as being the most convenient one for ourselves; and the other reason may have been, that, as most people are right-handed, and the common use of the right hand has made it the stronger, it is most conveniently employed in milking the hinder teats of the cow, which are often most difficult to reach on account of the position of the hind legs and the length of the hinder teats, or of the breadth of the hinder part of the udder. the near side is most commonly used in this country and in scotland; but in many parts of england the other side is preferred. whichever side is selected, that should uniformly be used, as cows are very sensitive to changes. in scotland it is a rare thing to see a cow milked by any other person than a woman, though men are very commonly employed at it in this country and in england. one never sees a man milking a cow without being impressed with the idea that he is usurping an office which does not become him; and the same thought seems to be conveyed in the terms usually applied to the person connected with cows--a dairy-_maid_ implying one who milks cows, as well as performs the other duties connected with the dairy--a dairy-_man_ meaning one who owns a dairy. there can be but little question that the charge of this branch of the dairy should generally be entrusted to women. they are more gentle and winning than men. the same person should milk the same cow regularly, and not change from one to another, unless there are special reasons for it. cows are easily rendered troublesome on being milked; and the kicks and knocks which they usually receive for their restlessness, only render them more fretful. if they cannot be overcome by kindness, thumps will never make them better. the truth is, restless habits are continued in them by the treatment which they receive at first, when, most probably, they have been dragooned into submission. their teats are tender at first; but an unfeeling, horny hand tugs at them at stripping, as if the animal had been accustomed to the operation for years. can the creature be otherwise than uneasy? and how can she escape the wincing but by flinging out her heels?--then hopples are placed on the hind fetlocks, to keep her heels down. the tail must then be held by some one, while the milking is going on; or the hair of its tuft be converted into a double cord, to tie the tail to the animal's leg. add to this the many threats and scoldings uttered by the milker, and one gets a not very exaggerated impression of the "breaking-in." some cows, no doubt, are very unaccomodating and provoking; but, nevertheless, nothing but a rational course toward them, administered with gentleness, will ever render them less so. there are cows which are troublesome to milk for a few times after calving, that become quite quiet for the remainder of the season; others will kick pertinaciously at the first milking. in this last case the safest plan--instead of hoppling, which only irritates--is for the dairymaid to thrust her head against the flank of the cow, and while standing on her feet, stretch her hands forward, get hold of the teats the best way she can, and send the milk on the ground; and in this position it is out of the power of the cow to hurt her. these ebullitions of feeling at the first milking after calving, arise either from feeling pain in a tender state of the teat, most probably from inflammation in the lining membrane of the receptacle; or they may arise from titillation of the skin of the udder and teat, which becomes the more sensible to the affection from a heat which is wearing off. at the age of two or three years the milking glands have not become fully developed, and their largest development will depend very greatly upon the management after the first calf. cows should have, therefore, the most milk-producing food; be treated with constant gentleness; never struck, or spoken harshly to, but coaxed and caressed; and in ninety-nine cases out of a hundred, they will grow up gentle and quiet. the hundredth had better be fatted and sent to the butcher. harshness is worse than useless. be the cause of irritation what it may, one thing is certain, that gentle discipline will overcome the most turbulent temper. nothing does so much to dry a cow up, especially a young cow, as the senseless treatment to which she is too often subjected. the longer the young cow, with her first and second calf, is made to hold out, the more surely will this habit be fixed upon her. stop milking her four months before the next calf, and it will be difficult to make her hold out to within four or six weeks of the time of calving afterward. induce her, if possible, by moist and succulent food, and by careful milking, to hold out even up to the time of calving, if you desire to milk her so long, and this habit will be likely to be fixed upon her for life. but do not expect to obtain the full yield of a cow the first year after calving. some of the very best cows are slow to develop their best qualities; and no cow reaches her prime till the age of five or six years. the extreme importance of care and attention to these points cannot be overestimated. the wild cows grazing on the plains of south america, are said to give not more than three or four quarts a day at the height of the flow; and many an owner of large herds in texas, it is said, has too little milk for family use, and sometimes receives his supply of butter from the new york market. there is, therefore, a constant tendency in milch cows to dry up; and it must be guarded against with special care, till the habit of yielding a large quantity, and yielding it long, becomes fixed in the young animal, when, with proper care, it may easily be kept up. cows, independently of their power to retain their milk in the udder, afford different degrees of pleasure in milking them, even in the quietest mood. some yield their milk in a copious flow, with the gentlest handling that can be given them; others require great exertion to draw the milk from them even in streams no larger than a thread. the udder of the former will be found to have a soft skin and short teats; that of the latter will have a thick skin, with long rough teats. the one feels like velvet; the other is no more pleasant to the touch than untanned leather. to induce quiet and persuade the animal to give down her milk freely, it is better that she should be fed at milking-time with cut feed, or roots, placed within her easy reach. if gentle and mild treatment is observed and persevered in, the operation of milking, as a general thing, appears to be a pleasure to the animal, as it undoubtedly is; but, if an opposite course is pursued--if at every restless movement, caused, perhaps, by pressing a sore teat, the animal is harshly spoken to--she will be likely to learn to kick as a habit, and it will be difficult to overcome it ever afterward. whatever may be the practice on other occasions, there can be no doubt that, for some weeks after calving, and in the height of the flow, cows ought, if possible, to be milked regularly three times a day--at early morning, noon, and night. every practical dairyman knows that cows thus milked give a larger quantity of milk than if milked only twice, though it may not be quite so rich; and in young cows, no doubt, it has a tendency to promote the development of the udder and milk-veins. a frequent milking stimulates an increased secretion, therefore, and ought never to be neglected in the milk-dairy, either in the case of young cows, or very large milkers, at the height of the flow, which will commonly be for two or three months after calving. there being a great difference in the quality as well as in the quantity of the milk of different cows, no dairyman should neglect to test the milk of each new addition to his dairy stock, whether it be an animal of his own raising or one brought from abroad. a lactometer--or instrument for testing the comparative richness of different species of milk--is very convenient for this purpose; but any one can set the milk of each cow separately at first, and give it a thorough trial, when the difference will be found to be great. economy will dictate that the cows least to the purpose should be disposed of, and their places supplied with better ones. the raising of calves. it has been found in practice that calves properly bred and raised on the farm have a far greater intrinsic value for that farm, other things being equal, than any that can be procured elsewhere; while on the manner in which they are raised will depend much of their future usefulness and profit. these considerations should have their proper weight in deciding whether a promising calf from a good cow and bull shall be kept, or sold to the butcher. but, rather than raise a calf at hap-hazard, and simply because its dam was celebrated as a milker, the judicious farmer will prefer to judge of the peculiar characteristics of the animal itself. this will often save the great and useless outlay which has sometimes been incurred in raising calves for dairy purposes, which a more careful examination would have rejected as unpromising. [illustration: maternal affection.] the method of judging stock which has been recommended in the previous pages is of practical utility here, and it is safer to rely upon it to some extent, particularly when other appearances concur, than to go on blindly. the milk-mirror on the calf is, indeed, small, but no smaller in proportion to its size than that of the cow; while its shape and form can generally be distinctly seen, particularly at the end of ten or twelve weeks. the development of the udder, and other peculiarities, will give some indication of the future capacities of the animal, and these should be carefully studied. if we except the manure of young stock, the calf is the first product of the cow, and as such demands our attention, whether it is to be raised or hurried off to the shambles. the practice adopted in raising calves differs widely in different sections of the country, being governed very much by local circumstances, as the vicinity of a milk-market, the value of milk for the dairy, the object of breeding, whether mainly for beef, for work, or for the dairy, etc.; but, in general, it may be said, that, within the range of thirty or forty miles of good veal-markets, which large towns furnish, comparatively few are raised at all. most of them are fattened and sold at ages varying from three to eight or ten weeks; and in milk-dairies still nearer large towns and cities they are often hurried off at one or two days, or, at most, a week old. in both of these cases, as long as the calf is kept it is generally allowed to suck the cow, and, as the treatment is very simple, there is nothing which particularly calls for remark, unless it be to condemn the practice entirely, upon the ground that there is a more profitable way of fattening calves for the butcher, and to say that allowing the calf to suck the cow at all is objectionable on the score of economy, except in cases where it is rendered necessary by the hard and swollen condition of the udder. if the calf is so soon to be taken away, it is better that the cow should not be suffered to become attached to it at all: since she is inclined to withhold her milk when it is removed, and thus a loss is sustained. the farmer will be governed by the question of profit, whatever course it is decided to adopt. in raising blood-stock, however, or in raising beef cattle, without any regard to economy of milk, the system of suckling the calves, or letting them run with the cow, may and will be adopted, since it is usually attended with somewhat less labor. the other course, which is regarded as the best where the calf is to be raised for the dairy, is to bring it up by hand. this is almost universally done in all countries where the raising of dairy cows is best understood--in switzerland, holland, some parts of germany, and england. it requires rather more care, on the whole; but it is decidedly preferable, since the calves cost less, as the food can be easily modified, and the growth is not checked, as is usually the case when the calf is taken off from the cow. allusion is here made, of course, to sections where the milk of the cow is of some account for the dairy, and where it is too valuable to be devoted entirely to nourishing the calf. in this case, as soon as the calf is dropped the cow is allowed to lick off the slimy moisture till it is dry, which she will generally do from instinct, or, if not, a slight sprinkling of salt over the body of the calf will immediately tempt her. the calf is left to suck once or twice, which it will do as soon as it is able to stand. it should, in all cases, be permitted to have the first milk which comes from the cow, which is of a turbid, yellowish color, unfit for any of the purposes of the dairy, but somewhat purgative and medicinal, and admirably and wisely designed by nature to free the bowels and intestines of the new-born animal from the mucous, excrementitious matter always existing in it after birth. too much of this new milk may, however, be hurtful even to the new-born calf, while it should never be given at all to older calves. the best course would seem to be--and such is in accordance with the experience of the most successful stock-raisers--to milk the cow dry immediately after the calf has sucked once, especially if the udder is painfully distended, which is often the case, and to leave the calf with the cow during one day, and after that to feed it by putting the fingers into its mouth, and gently bringing its muzzle down to the milk in a pail or trough when it will imbibe in sucking the fingers. no great difficulty will be experienced in teaching the calf to drink when taken so young, though some take to it much more readily than others. what the calf does not need should be given to the cow. some, however, prefer to milk immediately after calving; and, if the udder is overloaded, this may be the best course, though the better practice appears to be, to leave the cow as quietly to herself as possible for a few hours. the less she is disturbed, as a general thing, the better. the after-birth should be taken from her immediately after it is dropped. it is customary to give the cow, as soon as convenient after calving, some warm and stimulating drink--a little meal stirred into warm water, with a part of the first milk which comes from her, seasoned with a little salt. in many cases the calf is taken from the cow immediately; and before she has seen it, to a warm, dry pen out of her sight, and there rubbed till it is thoroughly dry; and then, when able to stand, fed with the new milk from the cow, which it should have three or four times a day, regularly, for the first fortnight, whatever course it is proposed to adopt afterwards. it is of the greatest importance to give the young calf a thrifty start. the milk, unless coming directly from the cow, should be warmed. some object to removing the calf from the cow in this way, on the ground of its apparent cruelty. but the objection to letting the calf suck the cow for several days, as they do, or indeed of leaving it with the cow for any length of time, is, that she invariably becomes attached to it, and frets and withholds her milk when it is at last taken from her. she probably suffers much more, after this attachment is once formed, at the removal of the object of it, than she does at its being taken at first out of her sight. the cow's memory is far more retentive than many suppose; and the loss and injury sustained by removing the calf after it has been allowed to suck her for a longer or shorter period are never known exactly, because it is not usually known how much milk the calf takes; but it is, without doubt, very considerable. if the udder is all right, there seems to be no good reason for leaving the calf with the cow for two or three days, if it is then to be taken away. the practice in holland is to remove the calf from its mother even before it has been licked, and to take it into a corner of the barn, or into another building, out of the cow's sight and hearing, put it on soft, dry straw, and rub it dry with some hay or straw, when its tongue and gums are slightly rubbed with salt, and the mucus and saliva removed from the nostrils and lips. after this has been done, the calf is made to drink the milk first taken as it comes from the mother. it is slightly diluted with water, if taken last from the udder; but, if the first of the milking, it is given just as it is. the calf is taught to drink in the same manner as in this country, by putting the fingers in its mouth, and bringing it down to the milk, and it soon gets so as to drink unaided. it is fed, at first, from four to six times a day, or even oftener; but soon only three times, at regular intervals. its food for two or three weeks is clear milk, as it comes warm and fresh from the cow. this is never omitted, as the milk during most of that time possesses certain qualities which are necessary to the calf, and which cannot be effectually supplied by any other food. in the third or fourth week the milk is skimmed, but warmed to the degree of fresh milk; though, as the calf grows a little older, the milk is given cold, while less care is taken to give it the milk of its own mother, that of other cows now answering equally well. in some places, calves are fed on buttermilk at the age of two weeks and after; but the change from new milk, fresh from the cow, is made gradually, some sweet skimmed milk and warm water being first added to it. at three weeks old, or thereabouts, the calf will begin to eat a little sweet, fine hay, and potatoes cut fine, and it very soon becomes accustomed to this food. many now begin to give linseed-meal mixed into hot water, to which is added some skim-milk or buttermilk; and others use a little bran cooked in hay-tea, made by chopping the hay fine and pouring on boiling-hot water, which is allowed to stand awhile on it. an egg is frequently broken into such a mixture. others still take pains at this age to have fresh linseed-cake, broken into pieces of the size of a pigeon's egg; putting one of these into the mouth after the meal of milk has been finished, and when it is eager to suck at any thing in its way. it will very soon learn to eat linseed-meal. a little sweet clover is put in its way at the age of about three weeks, and it will soon begin to eat that also. in this manner the feeding is continued from the fourth to the seventh week, the quantity of solid food being gradually increased. in the sixth or seventh week the milk is by degrees withheld, and water or buttermilk used instead; and soon after this, green food may be safely given, increasing it gradually with the hay to the age of ten or twelve weeks, when it will do to put them upon grass alone, if the season is favorable. a lot as near the house as possible, where they can be easily looked after and frequently visited, is the best. calves should be gradually accustomed to all changes; and even after having been turned out to pasture, they ought to be put under shelter if the weather is not dry and warm. the want of care and attention relative to these little details will be apparent sooner or later; while, if the farmer gives his personal attention to these matters, he will be fully paid in the rapid growth of his calves. it is especially necessary to see that the troughs from which they are fed, if troughs are used, are kept clean and sweet. but there are some--even among intelligent farmers--who make a practice of turning their calves out to pasture at the tender age of two or three weeks--and that, too, when they have sucked the cow up to that time--and allow them nothing in the shape of milk and tender care. this, certainly, is the poorest possible economy, to say nothing of the manifest cruelty of such treatment. the growth of the calf is checked, and the system receives a shock from so sudden a change, from which it cannot soon recover. the careful dutch breeders bring the calves either skimmed milk or buttermilk to drink several times a day after they are turned to grass, which is not till the age of ten or twelve weeks; and, if the weather is chilly, the milk is warmed for them. they put a trough generally under a covering, to which the calves may come and drink at regular times. thus, they are kept tame and docile. in the raising of calves, through all stages of their growth, great care should be taken neither to starve nor to over-feed. a calf should never be surfeited, and never be fed so highly that it cannot be fed more highly as it advances. the most important part is to keep it growing thriftily without getting too fat, if it is to be raised for the dairy. the calves in the dairy districts of scotland are fed on the milk, with seldom any admixture; and they are not permitted to suck their dams, but are taught to drink milk by the hand from a dish. they are generally fed on milk only for the first four, five, or six weeks, and are then allowed from two to two and a half quarts of new milk each meal, twice in the twenty-four hours. some never give them any other food when young except milk, lessening the quantity when the calf begins to eat grass or other food, which it generally does when about five weeks old, if grass can be had; and withdrawing it entirely about the seventh or eighth week of the calf's age. but, if the calf is reared in winter, or early in spring, before the grass rises, it must be supplied with at least some milk until it is eight or nine weeks old, as a calf will not so soon learn to eat hay or straw, nor fare so well on them alone as it will on pasture. some feed their calves reared for stock partly with meal mixed in the milk after the third or fourth week. others introduce gradually some new whey into the milk, first mixed with meal; and, when the calf gets older, they withdraw the milk, and feed it on whey and porridge. hay-tea, juices of peas and beans, or pea or bean-straw, linseed beaten into powder, treacle, etc., have all been sometimes used to advantage in feeding calves; but milk, when it can be spared, is, in the judgment of the scotch breeders, by far their most natural food. in galloway, and other pastoral districts, where the calves are allowed to suck, the people are so much wedded to their own customs as to argue that suckling is much more nutritious to the calves than any other mode of feeding. that it induces a greater secretion of saliva, which, by promoting digestion, accelerates the growth and fattening of the young animal, cannot be doubted; but the secretion of that fluid may likewise be promoted by placing an artificial teat in the mouth of the calf, and giving it the milk slowly, and at the natural temperature. in the dairy districts of scotland, the dairymaid puts one of her fingers into the mouth of the calf when it is fed, which serves the purpose of a teat, and will have nearly the same effect as the natural teat in inducing the secretion of saliva. if that, or an artificial teat of leather, be used, and the milk be given slowly before it is cold, the secretion of saliva may be promoted to all the extent that can be necessary; besides, secretion is not confined to the mere period of eating, but, as in the human body, the saliva is formed and part of it swallowed at all times. as part of the saliva is sometimes seen dropping from the mouths of the calves, it might be advisable not only to give them an artificial teat when fed, but to place, as is frequently done, a lump of chalk before them to lick, thus leading them to swallow the saliva. the chalk would so far supply the want of salt, of which cattle are often so improperly deprived, and it would also promote the formation of saliva. indeed, calves are very much disposed to lick and suck every thing which comes within their reach, which seems to be the way in which nature teaches them to supply their stomachs with saliva. [illustration: frolicksome.] but though sucking their dams may be most advantageous in that respect, yet it has also some disadvantages. the cow is always more injured than the calf is benefited by that mode of feeding. she becomes so fond of the calf that she does not, for a long time after, yield her milk freely to the dairyman. the calf does not when young draw off the milk completely, and when it is taken off by the hand, the cow withholds a part of her milk, and, whenever a cow's udder is not completely emptied every time she is milked, the lactic secretion--as before stated--is thereby diminished. feeding of calves by hand is also, in various respects, advantageous. instead of depending on the uncertain, or perhaps precarious supply of the dam, which may be more at first than the young animal can consume or digest, and at other times too little for its supply, its food can, by hand-feeding, be regulated to suit the age, appetite, and the purposes for which the calf is intended; other admixtures or substitutes can be introduced into the milk, and the quantity gradually increased or withdrawn at pleasure. this is highly necessary when the calves are reared for stock. the milk is in that case diminished, and other food introduced so gradually that the stomach of the young animal is not injured as it is when the food is too suddenly changed. and, in the case of feeding calves for the butcher, the quantity of milk is not limited to that of the dam--for no cow will allow a stranger-calf to suck her--but it can be increased, or the richest or poorest parts of the milk given at pleasure. such are, substantially, the views upon this subject which are entertained by the most judicious farmers in the first dairy districts of scotland. in those districts--where, probably, the feeding and management of calves are as well and as judiciously conducted as in any other part of great britain--the farmers' wives and daughters, or the female domestics, have the principal charge of young calves; and they are, doubtless, much better calculated for this duty than men, since they are more inclined to be gentle and patient. the utmost gentleness--as has been already remarked, in another connection--should always be observed in the treatment of all stock; but especially of milch cows, and calves designed for the dairy. persevering kindness and patience, will, almost invariably, overcome the most obstinate natures; while rough and ungentle handling will be repaid in a quiet kind of way, perhaps, by withholding the milk, which will always have a tendency to dry up the cow; or, what is nearly as bad, by kicking and other modes of revenge, which often contribute to the personal discomfort of the milker. the disposition of the cow is greatly modified, if not, indeed, wholly formed, by her treatment while young; and therefore it is best to handle calves as much as possible, and make pets of them, lead them with a halter, and caress them in various ways. calves managed in this way will always be docile, and suffer themselves to be approached and handled, both in the pasture and in the barn. with respect to the use of hay-tea--often used in this country, but more common abroad, where greater care and attention are usually bestowed upon the details of breeding--youatt says: "at the end of three or four days, or perhaps a week, or near a fortnight, after a calf has been dropped, and the first passages have been cleansed by allowing it to drink as much of the cow's milk as it feels inclined for, let the quantity usually allotted for a meal be mixed, consisting, for the first week, of three parts of milk and one part of hay-tea. _the only nourishing infusion of hay is that which is made from the best and sweetest hay, cut by a chaff-cutter into pieces about two inches long_, and put into an earthen vessel; over this, boiling water should be poured, and the whole allowed to stand for two hours, during which time it ought to be kept carefully closed. after the first week, the proportions of milk and hay-tea may be equal; then composed of two-thirds of hay-tea and one of milk; and at length, one-fourth part of milk will be sufficient. this food should be given to the calf in a lukewarm state _at least three, if not four times a day, in quantities averaging three quarts at a meal_, but gradually increasing to four quarts as the calf grows older. toward the end of the second month, beside the usual quantity given at each meal--composed of three parts of the infusion and one of milk--a small wisp or bundle of hay is to be laid before the calf, which will gradually come to eat it; but, if the weather is favorable, as in the month of may, the beast may be turned out to graze in a fine, sweet pasture, well sheltered from the wind and sun. this diet may be continued until toward the latter end of the third month, when, if the calf grazes heartily, each meal may be reduced to less than a quart of milk, with hay-water; or skimmed milk, or fresh buttermilk, may be substituted for new milk. at the expiration of the third month, the animal will hardly require to be fed by hand; though, if this should still be necessary, one quart of the infusion given daily--which, during the summer, need not be warmed--will suffice." the hay-tea should be made fresh every two days, as it soon loses its nutritious quality. this and other preparations are given, not because they are better than milk,--than which nothing is better adapted to fatten a calf, or promote its growth,--but simply to economize by providing the simplest and cheapest substitutes. experience shows that the first two or three calves are smaller than those which follow; and hence, unless they are pure-bred, and to be kept for the blood, they are not generally thought to be so desirable to raise for the dairy as the third or fourth, and those that come after, up to the age of nine or ten years. opinions upon this point, however, differ. according to the comparative experiments of a german agriculturist, cows which as calves had been allowed to suck their dams from two to four weeks, brought calves which weighed only from thirty-five to forty-eight pounds; while others, which as calves had been allowed to suck from five to eight weeks, brought calves which weighed from sixty to eighty pounds. it is difficult to see how there can be so great a difference, if, indeed, there be any; but it may be worthy of careful observation and experiment, and as such it is stated here. the increased size of the calf would be due to the increased size to which the cow would attain; and if as a calf she were allowed to run in the pasture with her dam for four or five months, taking all the milk she wanted, she would doubtless be kept growing on in a thriving condition. but taking a calf from the cow at four or even eight weeks must check its growth to some extent; and this may be avoided by feeding liberally, and bringing up by hand. after the calf is fully weaned, there is nothing very peculiar in the general management. a young animal will require for the first few months--say up to the age of six months--an average of five or six pounds daily of good hay, or its equivalent. at the age of six months, it will require from four and a half to five pounds; and at the end of the year, from three and a half or four pounds of good hay, or its equivalent, for every one hundred pounds of its live weight; or, in other words, about three and a half or four per cent. of its live weight. at two years old, it will require three and a half, and some months later, three per cent. of its live weight daily in good hay, or its equivalent. indian-corn fodder, either green or cured, forms an excellent and wholesome food at this age. the heifer should not be pampered, nor yet poorly fed or half starved, so as to receive a check in her growth. an abundant supply of good healthy dairy food and milk will do all that is necessary up to the time of her having her first calf--which should not ordinarily be till the age of three years, though some choose to allow them to come in at two, or a little over, on the ground that it early stimulates the secretion of milk, and that this will increase the milking propensity through life. this is undoubtedly the case, as a general rule; but greater injury is at the same time done by checking the growth, unless the heifer has been fed up to large size and full development from the start--in which case she may perhaps take the bull at fifteen or eighteen months without injury. even if a heifer comes in at two years, it is generally deemed desirable to let her run barren for the following year, which will promote her growth and more perfect development. the feeding which young stock often get is not such as is calculated to make good-sized or valuable cattle of them. they are often fed on the poorest of hay or straw through the winter, not infrequently left exposed to cold, unprotected and unhoused, and thus stinted in their growth. this is, surely, the very worst economy, or rather it is no economy at all. properly viewed, it is an extravagant wastefulness which no farmer can afford. no animal develops its good points under such treatment; and if the starving system is to be followed at all, it had better be after the age of two or three years, when the animal's constitution has attained the strength and vigor which may, possibly, enable it to resist ill treatment. to raise up first-rate milkers, it is absolutely necessary to feed on dairy food even when they are young. no matter how fine the breed is, if the calf is raised on poor, short feed, it will never be so good a milker as if raised on better keeping; and hence, in dairy districts, where calves are raised at all, they ought to be allowed the best pasture during the summer, and good, sweet and wholesome food during the winter. points of fat cattle. whatever theoretical objections may be raised against over-fed cattle, and great as may be the attempts to disparage the mountains of fat,--as highly-fed cattle are sometimes designated,--there is no doubt of the practical fact, that the best butcher cannot sell any thing but the best fatted beef; and of whatever age, size, or shape a half-fatted ox may be, he is never selected by judges as fit for human food. hence, a well-fatted animal always commands a better price per pound than one imperfectly fed, and the parts selected as the primest beef are precisely the parts which contain the largest deposits of fat. the rump, the crop, and the sirloin, the very favorite cuts,--which always command from twenty to twenty-five per cent. more than any other part of the ox,--are just those parts on which the largest quantities of fat are found; so that, instead of the taste and fashion of the age being against the excessive fattening of animals, the fact is, practically, exactly the reverse. where there is the most fat, there is the best lean; where there is the greatest amount of muscle, without its share of fat, that part is accounted inferior, and is used for a different purpose; in fact, so far from fat's being a disease, it is a condition of muscle, necessary to its utility as food,--a source of luxury to the rich, and of comfort to the poor, furnishing a nourishing and healthy diet for their families. fattening is a secretive power which grazing animals possess, enabling them to lay by a store of the superfluous food which they take for seasons of cold or scarcity. it collects round the angular bones of the animal, and gives the appearance of rotundity; hence the tendency to deposit fat is indicated, as has been stated, by a _roundness_ of form, as opposed to the _fatness_ of a milk-secreting animal. but its greatest use is, that it is a store of heat-producing aliment, laid up for seasons of scarcity and want. the food of animals, for the most part, may be said to consist of a saccharine, an oleaginous, and an albuminous principle. to the first belong all the starchy, saccharine, and gummy parts of the plants, which undergo changes in the digestive organs similar to fermentation before they can be assimilated in the system; by them also animal heat is sustained. in indolent animals, the oily parts of plants are deposited and laid up as fat; and, when vigor and strength fail, this is taken up and also used in breathing to supply the place of the consumed saccharine matter. the albuminous, or gelatinous principle of plants is mainly useful in forming muscle; while the ashes of plants, the unconsumable parts, are for the supply, mainly, of bone, hair, and horn, but also of muscle and of blood, and to supply the waste which continually goes on. now, there are several qualities which are essentially characteristic of a disposition to fatten. there have not, as yet, been any book-rules laid down, as in the case of m. guénon's indications of milking-cows; but there are, nevertheless, marks so definite and well understood, that they are comprehended and acted upon by every grazier, although they are by no means easy to describe. it is by skillful acumen that the grazier acquires his knowledge, and not by theoretical rules; observation, judgment, and experience, powerful perceptive faculties, and a keen and minute comparison and discrimination, are essential to his success. [illustration: points of cattle.] the first indication upon which he relies, is the _touch_. it is the absolute criterion of _quality_, which is supposed to be the keystone of perfection in all animals, whether for the pail or the butcher. the skin is so intimately connected with the internal organs, in all animals, that it is questionable whether even our schools of medicine might not make more use of it in a diagnosis of disease. of physiological tendencies in cattle, however, it is of the last and most vital importance. it must neither be thick, nor hard, nor adhere firmly to the muscles. if it is so, the animal is a hard grazer, a difficult and obstinate feeder--no skillful man will purchase it--such a creature must go to a novice, and even to him at a price so low as to tempt him to become a purchaser. on the other hand, the skin must not be thin, like paper, nor flaccid, nor loose in the hand, nor flabby. this is the opposite extreme, and is indicative of delicateness, bad, flabby flesh, and, possibly, of inaptitude to retain the fat. it must be _elastic_ and velvety, soft and pliable, presenting to the touch a gentle resistance, but so delicate as to give pleasure to the sensitive hand--a skin, in short, which seems at first to give an indentation from the pressure of the fingers, but which again rises to its place by a gentle elasticity. the _hair_ is of nearly as much importance as the skin. a hard skin will have straight and stiff hair; it will not have a curl, but be thinly and lankly distributed equally over the surface. a proper grazing animal will have a _mossy_ coat, not absolutely curled, but having a disposition to a graceful curl, a semifold, which presents a waving inequality; but as different from a close and straightly-laid coat, as it is from one standing off the animal at right angles, a strong symptom of disease. it will also, in a thriving animal, be licked here and there with its tongue, a proof that the skin is duly performing its functions. there must be, also, the full and goggle _eye_, bright and pressed outward by the fatty bed below; because, as this is a part where nature always provides fat, an animal capable of developing it to any considerable extent, will have its indications here, at least, when it exists in excess. so much for feeding qualities in the animal, and their conformations indicative of this kindly disposition. next come such formations of the animal itself as are favorable to the growth of fat, other things being equal. there must be _size_ where large weights are expected. christmas beef, for instance, is expected to be large as well as fat. the symbol of festivity should be capacious, as well as prime in quality. but it is so much a matter of choice and circumstance with the grazier, that profit alone will be his guide. the axiom will be, however, as a general rule, that the better the grazing soil the larger the animal may be; the poorer the soil, the smaller the animal. small animals are, unquestionably, much more easily fed, and they are well known by experienced men to be best adapted to second-rate feeding pastures. but, beyond this, there must be _breadth_ of carcass. this is indicative of fattening, perhaps, beyond all other qualifications. if rumps are favorite joints and produce the best price, it is best to have the animal which will grow the longest, the broadest, and the best rump; the same of crop, and the same of sirloin; and not only so, but breadth is essential to the consumption of that quantity of food which is necessary to the development of a large amount of fat in the animal. thus, a deep, wide chest, favorable for the respiratory and circulating functions, enables it to consume a large amount of food, to take up the sugary matter, and to deposit the fatty matter,--as then useless for respiration, but afterwards to be prized. a full level crop will be of the same physiological utility; while a broad and open framework at the hips will afford scope for the action of the liver and kidneys. there are other points, also, of much importance; the head must be small and fine; its special use is indicative of the quick fattening of the animal so constructed, and it is also indicative of the bones being small and the legs short. for constitutional powers, the beast should have his ribs extended well towards the thigh-bones or hips, so as to leave as little unprotected space as possible. there must be no angular, or abrupt points; all must be round, and broad, and parallel. any depression in the lean animal will give a deficient deposit of flesh and fat at that point, when sold to the butcher, and thus deteriorate its value; and hence the animal must be round and full. but either fancy, or accident, or skill--it is unnecessary to decide which--has associated _symmetry_ with quality and conformation, as a point of great importance in animals calculated for fattening; and there is no doubt that, to a certain extent, this is so. the beast must be a system of mathematical lines. to the advocate of symmetry, the setting-on of a tail will be a condemning fault; indeed the ridge of the back, like a straight line, with the outline of the belly exactly parallel, viewed from the side, and a depth and squareness when viewed from behind,--which remind us of a geometrical cube, rather than a vital economy,--may be said to be the indications of excellence in a fat ox. the points of excellence in such an animal are outlined under the subsequent head, as developed in the cutting up after slaughter. now, these qualities are inherent in some breeds; there may be cases and instances in all the superior breeds, and in most there may be failures. driving and slaughtering. it is necessary that cattle which have been disposed of to the dealer or butcher, or which are intended to be driven to market, should undergo a preparation for the journey. if they were immediately put to the road to travel, from feeding on grass or turnips, when their bowels are full of undigested vegetable matter, a scouring might ensue which would render them unfit to pursue their journey; and this complaint is the more likely to be brought on from the strong propensity which cattle have to take violent exercise upon feeling themselves at liberty after a long confinement. they in fact, become light-headed whenever they leave the barn or enclosure, so much so that they actually "frisk and race and leap," and their antics would be highly amusing, were it not for the apprehension that they may hurt themselves against some opposing object, as they seem to regard nothing before them. on being let out for the first time, cattle should be put for awhile into a larger court, or on a road well fenced with enclosures, and guarded by men, to romp about. two or three such allowances of liberty will render them quiet; and, in the mean time, to lighten their weight of carcass, they should have hay for a large proportion of their food. these precautions are absolutely necessary for cattle which have been confined in barns; otherwise, accidents may befall them on the road, where they will at once break loose. even at home serious accidents sometimes overtake them, such as the breaking down of a horn, casting off a hoof, spraining a tendon, bruising ribs, and heating the whole body violently; and, of course, when any such ill luck befalls, the animal affected must be left behind, and become a drawback upon the value of the rest, unless kept for some time longer. having the cattle prepared for travel, the drover takes the road very slowly for the first two days, not exceeding seven or eight miles a day. at night, in winter, they should be put into an open court, and supplied with hay, water, and a very few turnips; for, if roots are suddenly withdrawn from them,--since it is taken for granted that these have formed a staple portion of their food,--their bellies will become shrunken up into smaller dimensions--a state very much against favorable appearance in market. after the first two days they may proceed faster, say twelve or thirteen miles a day, if very fat; and fifteen, if moderately so. when the journey is long and the beasts get faint from travel, they should have corn to support them. in frosty weather, when the roads become very hard, they are apt to become shoulder-shaken, an effect of founder; and if sleet falls during the day, and becomes frozen upon them at night, they may become so chilled as to refuse food, and shrink rapidly away. cattle should, if possible, arrive the day before in the neighborhood of a distant market, and be supplied with a good feed of roots and hay, or grass, to make them look fresh and fill them up again; but if the market is at but short distance, they can travel to it early in the morning. [illustration: a frontispiece.] in driving cattle the drover should have no dog, which will only annoy them. he should walk either before or behind, as he sees them disposed to proceed too fast or to loiter upon the road; and in passing carriages, the leading ox, after a little experience, will make way for the rest to follow. on putting oxen on a ferry-boat the shipping of the first one only is attended with much trouble. a man on each side should take hold of a horn, or of a halter made of any piece of rope, should the beast be hornless, and two other men, one on each side, should push him up behind with a piece of rope held between them as a breeching, and conduct him along the plank into the boat; if it have low gunwales, a man will be required to remain beside him until one or two more of the cattle follow their companion, which they will most readily do. from neglecting this precaution in small ferry-boats, the first beast sometimes leaps into the water, when it becomes a difficult task to prevent some of the rest doing the same thing. whatever time a lot of cattle may take to go to a market, they should never be _overdriven_. there is great difference of management in this respect among drovers. some like to proceed upon the road quietly, slowly, but surely, and to reach the market in a placid, cool state. others, again, drive smartly along for some distance, and then rest to cool awhile, when the beasts will probably get chilled and have a staring coat when they reach their destination; while others like to enter the market with their beasts in an excited state, imagining that they then look gay; but distended nostrils, loose bowels, and reeking bodies are no recommendations to a purchaser. good judges are shy of purchasing cattle in a heated state, because they do not know how long they may have been in it; and to cover any risk, will give at least five dollars a head below what they would have offered for them in a cool state. some drovers have a habit of thumping at the hindmost beast of the lot with a stick while on the road. this is a censurable practice, as the flesh, where it is thumped, will bear a red mark after the animal has been slaughtered,--the mark receiving the appropriate name of _blood-burn_--and the flesh thus affected will not take on salt, and is apt to putrefy. a touch up on the shank, or any tendonous part, when correction is necessary, is all that is required; but the voice, in most cases, will answer as well. the flesh of overdriven cattle, when slaughtered, never becomes properly firm, and their tallow has a soft, melted appearance. a few large oxen in one lot look best in a market on a position rather above the eye of a spectator. when a large lot is nearly alike in size and appearance, they look best and most level on a flat piece of ground. very large fat oxen never look better than on ground on the same level with the spectator. an ox, to look well, should hold his head on a line with the body, with lively ears, clear eye, dewy nose, a well-licked hide, and should stand firmly on the ground on all his feet. these are all symptoms of high health and good condition. whenever an ox shifts his standing from one foot to another, he is _foot-sore_, and has been driven far. whenever his head hangs down and his eyes water, he feels ill at ease inwardly. when his coat stares, he has been overheated some time, and has got a subsequent _chill_. all these latter symptoms will be much aggravated in cattle that have been fed in a barn. cattle are made to fast before being slaughtered. the time they should stand depends upon their state on their arrival at the shambles. if they have been driven a considerable distance in a proper manner, the bowels will be in a tolerably empty state, so that twelve hours may suffice; but if they are full and just off their food, twenty-four hours will be required. beasts that have been overdriven, or much struck with sticks, or in any degree infuriated, should not be immediately slaughtered, but allowed to stand on dry food, such as hay, until the symptoms disappear. these precautions are absolutely necessary that the meat may be preserved in the best state. the mode of slaughtering cattle varies in different countries. in the great slaughter-houses at montmartre, in paris, they are slaughtered by bisecting the spinal cord of the cervical vertebræ; and this is accomplished by the driving of a sharp-pointed chisel between the second and third vertebræ, with a smart stroke of a mallet, while the animal is standing, when it drops, and death or insensibility instantly ensues, and the blood is let out immediately by opening the blood-vessels of the neck. the plan adopted in england is, first to bring the ox down on his knees, and place his under-jaw upon the ground by means of ropes fastened to his head and passed through an iron ring in the floor of the slaughterhouse. he is then stunned with a few blows from an iron axe made for the purpose, on the forehead, the bone of which is usually driven into the brain. the animal then falls upon his side, and the blood is let out by the neck. of the two modes, the french is apparently the less cruel, for some oxen require many blows to make them fall. some butchers, however, allege that the separation of the spinal cord, by producing a general nervous convulsion throughout the body, prevents the blood from flowing as rapidly and entirely out of it as when the ox is stunned in the forehead. the skin is then taken off to the knees, when the legs are disjointed, and also off the head. the carcass is then hung up by the tendons of the hough on a stretcher, by a block and tackle, worked by a small winch, which retains in place what rope it winds up by means of a wheel and ratchet. after the carcass has hung for twenty-four hours, it should be cut down by the back-bone, or chine, into two _sides_. this is done either with the saw, or chopper; the saw making the neatest job in the hands of an inexperienced butcher, though it is the most laborious; and with the chopper is the quickest, but by no means the neatest plan, especially in the hands of a careless workman. in london, the chine is equally divided between both sides; while in scotland, one side of a carcass of beef has a great deal more bone than the other, all the spinous processes of the vertebræ being left upon it. the bony is called the _lying_ side of the meat. in london, the divided processes in the fore-quarters are broken in the middle when warm, and chopped back with the flat side of the chopper, which has the effect of thickening the fore and middle ribs considerably when cut up. the london butcher also cuts the joints above the hind knee, and, by making some incisions with a sharp knife, cuts the tendons there, and drops the flesh of the hind-quarter on the flank and loins, which causes it to cut up thicker than in the scotch mode. in opening the hind-quarter he also cuts the aitch bone, or pelvis through the centre, which makes the rump look better. some butchers in the north of england score the fat of the _closing_ of the hind-quarter, which has the effect of making that part of both heifer and ox look like the udder of an old cow. there is far too much of this scoring practised in scotland, which prevents the pieces from retaining--which they should, as nearly as possible--their natural appearance. in cutting up a carcass of beef the london butcher displays great expertness; he not only discriminates between the qualities of its different parts, but can cut out any piece to gratify the taste of his customers. in this way he makes the best use of the carcass and realizes the largest value for it, while he gratifies the taste of every grade of customers. a figure of the scotch and english modes of cutting up a carcass of beef will at once show the difference; and upon being informed where the valuable pieces lie, an opinion can be formed as to whether the oxen the farmer is breeding or feeding possess the properties which will enable him to demand the highest price for them. [illustration: scotch mode of cutting up beef.] the sirloin is the principal roasting-piece, making a very handsome dish, and is a universal favorite. it consists of two portions, the scotch and english sides; the former is above the lumbar bones, and is somewhat hard in ill-fed cattle; the latter consists of the muscles under these bones, which are generally covered with fine fat, and are exceedingly tender. the better the beast is fed, the larger is the under muscle, better covered with fat, and more tender to eat. the hook-bone and the buttock are cut up for steaks, beefsteak pie, or minced collops, and both these, together with the sirloin, bring the highest price. the large round and the small round are both well known as excellent pieces for salting and boiling, and are eaten cold with great relish. the hough is peculiarly suited for boiling down for soup, having a large proportion of gelatinous matter. brown soup is the principal dish made of the hough, but its decoction forms an excellent _stock_ for various dishes, and will keep in a state of jelly for a considerable time. the thick and the thin flank are both admirable pieces for salting and boiling. the tail, insignificant as it may seem, makes a soup of a very fine flavor. hotel-keepers have a trick of seasoning brown soup or rather beef-tea, with a few joints of tail, and passing it off for genuine ox-tail soup. these are all the pieces which constitute the hind-quarter; and it will be seen that they are valuable both for roasting and boiling, not containing a single coarse piece. in the fore-quarter, is the spare rib, the six ribs of the back end of which make an excellent roast, and when taken from the side opposite to the _lying_ one, being free of the bones of the spine, it makes a large one; and it also makes excellent beefsteaks and beefsteak pie. the two runners and the nineholes make salting and boiling pieces; but, of these, the nineholes is much the best, as it consists of layers of fat and lean without any bone; whereas the fore parts of the runners have a piece of shoulder-blade in them, and every piece connected with that bone is more or less coarse-grained. the brisket eats very well boiled fresh in broth, and may be cooked and eaten with boiled greens or carrots. the shoulder-lyar is a coarse piece, and fit only for boiling fresh to make into broth or beef-tea. the nap, or shin, is analogous to the hough of the hind-leg, but not so rich and fine, there being much less gelatinous matter in it. the neck makes good broth; and the sticking-piece is a great favorite with some epicures, on account of the pieces of rich fat in it. it makes an excellent stew, as also sweet barley-broth, and the meat eats well when boiled in it. these are all the pieces of the fore-quarter; and it will be seen that they consist chiefly of boiling-pieces, and some of them none of the finest--the roasting-piece being confined to the six ribs of the spare rib, and the finest boiling-piece, corned, only to be found in the nineholes. [illustration: english mode of cutting up beef.] the loin is the principal roasting-piece; the rump is the favorite steak-piece; the aitch-bone, the favorite stew; the buttock, the thick flank, and the thin flank are all excellent boiling-pieces when corned; the hock and the shin make soup and afford stock for the various requirements of the culinary art; and the tail furnishes ox-tail soup--a favorite english luncheon. these are all the pieces of the hind-quarter, and they are valuable of their respective kinds. in the fore-quarter, the fore-rib, middle-rib, and chuckle-rib are all roasting-pieces, not alike good; but in removing the part of the shoulder-blade in the middle-rib, the spare-ribs below make a good broil or roast; the neck makes soup, being used fresh, boiled; the back end of the brisket is boiled, corned, or stewed; the leg-of-mutton piece is coarse, but is as frequently stewed as boiled; the shin is put to the same use as the shin and hock of the hind-quarter. on comparing the two modes of cutting-up, it will be observed that in the english there are more roasting-pieces than in the scotch, a large proportion of the fore-quarter being used in that way. the plan, too, of cutting the loin between the rump and aitch-bone in the hind-quarter, lays open the steak-pieces to better advantage than in the scotch bullock. extending the comparison from one part of the carcass to the other, in both methods, it will be seen that the most valuable pieces--the roasting--occupy its upper, and the less valuable--the boiling--its lower part. every beast, therefore, that lays on beef more upon the upper part of its body is more valuable than one that lays the same quantity of flesh on its lower parts. it is deemed unnecessary to enter into details as to the modes of cutting-up most in vogue in this country, as there is a needlessly great want of uniformity. of the qualities of beef obtained from the different breeds of cattle in england, there is no better meat than from the west highlanders for fineness of grain and cutting up into convenient pieces for family use. the galloways and angus, when fattened in english pastures, are great favorites in the london market. the short horns afford excellent steaks, being thick of flesh, and the slice deep, large and juicy, and their covered flanks and nineholes are always thick, juicy, and well-mixed. the herefords are somewhat similar to the short horns, and the devons, may, perhaps, be classed among the galloways and angus, while the welsh cannot be compared to the west highlanders. taking, then, the breeds of scotland as suppliers of good beef, they seem to be more valuable for the table than those of england. there are, perhaps, not sufficient data in existence to determine the true proportion of offal of all kinds to the beef of any given fat ox; but approximations have been made, which may serve the purpose until the matter is investigated by direct experiment, under various circumstances. the dead weight bears to the live weight a ratio varying between .571 and .605 to 1; and on applying one or the other multiplier to the cases of the live weight, a pretty correct approximation is reached. the tallow is supposed to be eight one-hundredths of the live weight; so that the multiplier is the decimal .08. the hide is supposed to be five one-hundredths of the live weight; so to obtain its weight, a multiplier, .05, is used. the other offals are supposed to be in a proportion of about one-fourth of the live weight; so that the multiplier, .28, is as near as can be proposed under existing experience. beef is the staple animal food of this country, and it is used in various states--fresh, salted, smoked, roasted, and boiled. when intended to be eaten fresh, the _ribs_ will keep the best, and with care will keep five or six days in summer, and in winter ten days. the middle of the _loin_ is the next best, and the _rump_ the next. the _round_ will not keep long, unless it is salted. the _brisket_ is the worst, and will not keep more than three days in summer, and in winter a week. in regard to the power of the stomach to digest beef, that which is eaten boiled with salt only, is digested in two hours and forty-five minutes. beef, fresh, lean, and rarely-roasted, and a beefsteak broiled, takes three hours to digest; that fresh, and dry-roasted, and boiled, eaten with mustard, is digested in three and a half hours. lean fresh beef fried, requires four hours, and old hard salted beef boiled, does not digest in less than four and a quarter hours. fresh beef-suet boiled takes five and a half hours. the usual mode of preserving beef is by salting; and, when intended to keep for a long time, such as for the use of shipping, it is always salted with brine; but for family use it should be salted only with good salt; for brine dispels the juice of meat, and saltpetre only serves to make the meat dry, and give it a disagreeable and unnatural red color. various experiments have been made in curing beef with salt otherwise than by hand-rubbing, and in a short space of time, and also to preserve it from putrefaction by other means than salt. some packers put meat in a copper which is rendered air-tight, and an air-pump then creates a vacuum within it, thereby extracting all the air out of the meat; then brine is pumped in by pressure, which, entering into every pore of the meat formerly occupied by the air, is said to place it in a state of preservation in a few minutes. the carcass of an ox was preserved, in france, for two years from putrefaction by injecting four pounds of saline mixture into the carotid artery. whether any such contrivance can be made available for family purposes, seems doubtful. cattle, when slaughtered, are useful to man in various other ways than by affording food from their flesh,--their offal of tallow, hides, and horns, forming extensive articles of commerce. of the _hide_, the characteristics of a good one for strong purposes are strength in its middle, or _butt_, as it called, and lightness in the edges, or _offal_. a bad hide is the opposite of this--thick in the edges and thin in the middle. a good hide has a firm texture; a bad one, loose and soft. a hide improves as the summer advances, and it continues to improve after the new coat of hair in autumn until november or december, when the coat gets rough from the coldness of the season, and the hide is then in its best state. it is surprising how a hide improves in thickness after the cold weather has set in. the sort of food does not seem to affect the quality of the hide; but the better it is, and the better cattle have been fed, and the longer they have been well fed, even from a calf, the better the hide. from what has been said of the effect of weather upon the hide, it seems a natural conclusion that a hide is better from an ox that has been fed in the open air, than from one that has been kept in the barn. dirt adhering to a hide injures it, particularly in stall-fed animals; and any thing that punctures a hide, such as warbles arising from certain insects, is also injurious. the best hides are obtained from the west highlanders. the short horns produce the thinnest hides, the aberdeenshire the next, and then the angus. of the same breed, the ox affords the strongest hide; but, as hides are applied to various uses, the cow's, provided it be large, may be as valuable as that of the ox. the bull's hide is the least valuable. hides are imported from russia and south america. hides, when deprived of their hair, are converted into _leather_ by an infusion of the astringent property of bark. the old plan of tanning used to occupy a long time; but, such was the value of the process, that the old tanners used to pride themselves upon producing a substantial article--which is more than can be said in many instances under modern improved modes, which hasten the process, much to the injury of the article produced. strong infusions of bark make leather brittle; one hundred pounds of skin, quickly tanned in a strong infusion, produce one hundred and thirty-seven pounds of leather; while a weak infusion produces only one hundred and seventeen and a half,--the additional nineteen and a half pounds serving only to deteriorate the leather, and causing it to contain much less textile animal solid. leather thus highly charged with tanning is so spongy as to allow moisture to pass readily through its pores, to the great discomfort and injury of those who wear shoes made of it. the proper mode of tanning lasts a year, or a year and a half, according to the quality of the leather wanted and the nature of the hides. a perfect leather can be recognized by its section, which should have a glistening marbled appearance, without any white streaks in the middle. the hair which is taken off hides in tanning, is employed to mix with plaster, and is often surreptitiously put into hair-mattresses. the principal substances of which _glue_ is made are the parings of ox and other thick hides, which form the strongest article and the refuse of the leather-dresser. both afford from forty-five to fifty-five per cent. of glue. the tendons, and many other offals of slaughter-houses, also afford materials, though of an inferior quality, for this purpose. the refuse of tanneries--such as the ears of oxen and calves--are better articles. animal skins also, in any form, uncombined with tannin, may be worked into glue. _ox-tallow_ is of great importance in the arts. candles and soap are made of it, and it enters largely into the dressing of leather and the use of machinery. large quantities are annually exported from russia. ox-tallow consists of seventy-six parts of stearine and twenty-four of oleine, out of one hundred parts. the _horns_ of oxen are used for many purposes. the horn consists of two parts: an outward horny case, and an inward conical-shaped substance, somewhat intermediate between indurated hair and bone, called the _fluid_ of the horn. these two parts are separated by means of a blow upon a block of wood. the horny exterior is then cut into three portions by means of a frame saw. the lowest of these, next the root of the horn, after undergoing several processes by which it is rendered flat, is made into combs. the middle of the horn, after having been flattened by heat, and its transparency improved by oil, is split into thin layers, and forms a substitute for glass in lanterns of the commonest kind. the tip of the horns is used by makers of knife-handles and of the tops of whips, and for other similar purposes. the interior, or core of the horn, is boiled down in water. a large quantity of fat rises to the surface; this is put aside, and sold to the makers of yellow soap. the itself is used as a kind of glue, and is purchased by the cloth-draper for stiffening. the bony substance remaining behind is then sent to the mill, and, after having been ground down, is sold to farmers for manure. besides these various purposes to which the different parts of the horn are applied, the clippings which arise in comb-making are sold to the farmer for manure, as well as the shavings which form the refuse of the lantern-makers. horn, as is well known, is easily rendered soft and pliant in warm water; and by this peculiarity and its property of adhering like glue, large plates of horn can be made by cementing together the edges of small pieces rendered flat by a peculiar process, as a substitute for glass. imitation of tortoise-shell can be given to horn by means of various metallic solutions. horn, also, when softened, can be imprinted with any pattern, by means of dies. [illustration] diseases and their remedies under this head it is proposed to notice such diseases as are most common among cattle, together with their symptoms, and to suggest such treatment of the same as has been found in the practice of the author, in the main, effective. he is aware that much more space might have been appropriated to this head, as has been the case in other treatises of this class; but he doubts the propriety of multiplying words about diseases which are of very rare occurrence, deeming it more fitting to leave such instances exclusively to the intelligent consideration of the reliable veterinary practitioner. for convenience of reference, the diseases here noticed have been arranged in alphabetical order; the whole concluding with information as to two or three operations which cannot be uninteresting to, or unprofitable for, the reader. abortion. the cow is, more than any other animal, subject to abortion, or slinking, which takes place at different periods of pregnancy, from half of the usual time to the seventh, or almost to the eighth month. the symptoms of the approach of abortion, unless the breeder is very much among his stock, are not often perceived; or, if perceived, they are concealed by the person in charge, lest he should be accused of neglect or improper treatment. the cow is somewhat off her feed--rumination ceases--she is listless and dull--the milk diminishes or dries up--the motions of the foetus become more feeble, and at length cease altogether--there is a slight degree of enlargement of the belly--there is a little staggering in her walk--when she is down she lies longer than usual, and when she gets up she stands for a longer time motionless. as the abortion approaches, a yellow or red glairy fluid runs from the vagina (this is a symptom, which rarely, or never, deceives) her breathing becomes laborious and slightly convulsive. the belly has for several days lost its natural rotundity, and has been evidently falling,--she begins to moan,--the pulse becomes small, wiry, and intermittent. at length labor comes on, and is often attended with much difficulty and danger. if the abortion has been caused by blows or violence, whether from brutality, or the animal's having been teased by other cows in season, or by oxen, the symptoms are more intense. the animal suddenly ceases to eat and to ruminate--is uneasy, paws the ground, rests her head on the manger while she is standing, and on her flank when she is lying down--hemorrhage frequently comes on from the uterus, or when this is not the case the mouth of that organ is spasmodically contracted. the throes come on, are distressingly violent, and continue until the womb is ruptured. if all these circumstances be not observed, still the labor is protracted and dangerous. abortion is sometimes singularly frequent in particular districts, or on particular farms, appearing to assume an epizoötic or epidemic form. this has been accounted for in various ways. some have imagined it to be contagious. it is, indeed, destructively propagated among the cows, but this is probably to be explained on a different principle from that of contagion. the cow is a considerably imaginative animal, and highly irritable during the period of pregnancy. in abortion, the foetus is often putrid before it is discharged; and the placenta, or after-birth, rarely or never follows it, but becomes decomposed, and, as it drops away in fragments, emits a peculiar and most noisome smell. this smell seems to be peculiarly annoying to the other cows: they sniff at it and then run bellowing about. some sympathetic influence is exercised on their uterine organs, and in a few days a greater or less number of those that had pastured together likewise abort. hence arises the rapidity with which the foetus is usually taken away and buried deeply, and far from the cows; and hence the more effectual preventive of smearing the parts of the cow with tar or stinking oils, in order to conceal or subdue the smell; and hence, too, the inefficacy, as a preventive, of removing her to a far-distant pasture. the pastures on which the blood or inflammatory fever is most prevalent are those on which the cows oftenest slink their calves. whatever can become a source of general excitation and fever is likely, during pregnancy, to produce inflammation of the womb; or whatever would, under other circumstances, excite inflammation of almost any organ, has at that time its injurious effect determined to this particular one. every farmer is aware of the injurious effect of the coarse, rank herbage of low, marshy, and woody countries, and he regards these districts as the chosen residence of red water; it may be added, that they are also the chosen residence of abortion. hard and mineral waters are justly considered as laying the foundation of many diseases among cattle, and of abortion among the rest. some careful observers have occasionally attributed abortion to disproportion in size between the male and the female. farmers were formerly too fond of selecting a great overgrown bull to serve their dairy or breeding cows, and many a heifer, or little cow, was seriously injured; and she either cast her calf, or was lost in parturition. the breeders of cattle in later years are beginning to act more wisely in this matter. cows that are degenerating into consumption are exceedingly subject to abortion. they are continually in heat; they rarely become pregnant, or if they do, a great proportion of them cast their calves. abortion, also, often follows a sudden change from poor to luxuriant food. cows that have been out, half-starved in the winter, when incautiously turned on rich pasture in the spring, are too apt to cast their calves from the undue general or local excitation that is set up. hence it is, that when this disposition to abort first appears in a herd, it is naturally in a cow that has been lately purchased. fright, from whatever cause, may produce this trouble. there are singular cases on record of whole herds of cows slinking their calves after having been terrified by an unusually violent thunder-storm. commerce with the bull soon after conception is also a frequent cause, as well as putrid smells--other than those already noticed--and the use of a diseased bull. besides these tangible causes of abortion, there is the mysterious agency of the atmosphere. there are certain seasons when abortion is strangely frequent, and fatal; while at other times it disappears in a manner for several successive years. the consequences of premature calving are frequently of a very serious nature; and even when the case is more favorable, the results are, nevertheless, very annoying. the animal very soon goes again to heat, but in a great many cases she fails to become pregnant; she almost invariably does so, if she is put to the bull during the first heat after abortion. if she should come in calf again during that season, it is very probable that at about the same period of gestation, or a little later, she will again abort: or that when she becomes in calf the following year, the same fatality will attend her. some say that this disposition to cast her young gradually ceases; that if she does miscarry, it is at a later and still later period of pregnancy; and that, in about three or four years, she may be depended upon as a tolerably safe breeder. he, however, would be sadly inattentive to his own interests who keeps a profitless beast so long. the calf very rarely lives, and in the majority of cases it is born dead or putrid. if there should appear to be any chance of saving it, it should be washed with warm water, carefully dried, and fed frequently with small quantities of new milk, mixed, according to the apparent weakness of the animal, either with raw eggs or good gruel; while the bowels should, if occasion requires, be opened by means of small doses of castor-oil. if any considerable period is to elapse before the natural time of pregnancy would have expired, it will usually be necessary to bring up the little animal entirely by hand. the treatment of abortion differs but little from that of parturition. if the farmer has once been tormented by this pest in his dairy, he should carefully watch the approaching symptoms of casting the calf, and as soon as he perceives them, should remove the animal from the pasture to a comfortable cow-house or shed. if the discharge be glairy, but not offensive, he may hope that the calf is not dead; he will be assured of this by the motion of the foetus, and then it is possible that the abortion may still be avoided. he should hasten to bleed her, and that copiously, in proportion to her age, size, condition, and the state of excitation in which he may find her; and he should give a dose of physic immediately after the bleeding. when the physic begins to operate, he should administer half a drachm of opium and half an ounce of sweet spirits of nitre. unless she is in a state of great debility, he should allow nothing but gruel, and she should be kept as quiet as possible. by these means he may occasionally allay the general or local irritation that precedes or causes the abortion, and the cow may yet go to her full time. should, however, the discharge be fetid, the conclusion will be that the foetus is dead, and must be got rid of, and that as speedily as possible. bleeding may even then be requisite if much fever exists; or, perhaps, if there is debility, some stimulating drink may not be out of place. in other respects the animal must be treated as if her usual time of pregnancy had been accomplished. much may be done in the way of preventing this habit of abortion among cows. _the foetus must be got rid of immediately._ it should be buried deep, and far from the cow-pasture. proper means should be taken to hasten the expulsion of the placenta. a dose of physic should be given; ergot of rye administered; the hand should be introduced, and an effort made, cautiously and gently, to detach the placenta; all violence, however, should be carefully avoided; for considerable and fatal hemorrhage may be speedily produced. the parts of the cow should be well washed with a solution of the chloride of lime, which should be injected up the vagina, and also given internally. in the mean time, and especially after the expulsion of the placenta, the cow-house should be well washed with the same solution. the cow, when beginning to recover, should be fattened and sold. this is the first and the grand step toward the prevention of abortion, and he is unwise who does not immediately adopt it. all other means are comparatively inefficient and worthless. should the owner be reluctant to part with her, two months, at least, should pass before she is permitted to return to her companions. prudence would probably dictate that she should never return to them, but be kept, if possible, on some distant part of the farm. abortion having once occurred among the herd, the breeding cows should be carefully watched. although they should be well fed, they should not be suffered to get into too high condition. unless they are decidedly poor and weak, they should be bled between the third and fourth months of pregnancy, and a mild dose of physic administered to each. if the pest continues to reappear, the owner should most carefully examine how far any of the causes of abortion that have been detected, may exist on his farm, and exert himself to thoroughly remove them. an interesting paper upon this subject may be found in the veterinary review, vol. 1., p. 434, communicated by prof. henry tanner, of queen's college, birmingham, england. as it suggests a theory as to the origin of this disease which is, to say the least, quite plausible, we transfer the article:-"i shall not go into any notice of the general subject of abortion, but rather restrict my remarks to a cause which is very much overlooked, and yet which is probably more influential than all other causes combined. i refer to the growth of ergotized grass-seeds in our pastures. "the action of ergot of rye (_secale cornutum_) upon the womb is well known as an excitant to powerful action, which usually terminates in the expulsion of the foetus. we have a similar disease appearing on the seeds of our grasses, but especially on the rye grass, and thus we have an ergot of the seeds of rye grass produced, possessing similar exciting powers upon the womb to those produced by the ergot of rye. "two conditions are necessary for the production of this ergot upon the seed of rye grass. the first is, the grass must be allowed to run to seed; and the second is, that the climate must be favorable for encouraging the development of the ergot. "in practice, we find that on land which has been fed on during the summer, unless it has been grazed with unusual care, much of the grass throws up seed-stalks and produces seed. in districts where the climate is humid and rain abundant, as well as in very wet seasons, these seeds become liable to the growth of this ergot. cattle appear to eat it with a relish, and the result is that abortion spreads rapidly through the herd. heifers and cows, which, up to the appearance of the ergot, have held in calf, are excited to cast their calves by consuming it in their food. the abortion having once commenced, we know that the peculiarly sensitive condition of the breeding animal will cause its extension, even where the original cause may not be in operation; but their combined action renders the loss far more serious. if we add to this the tendency which an animal receives from her first abortion, to repeat it when next in calf, we see how seriously the mischief becomes multiplied. "a somewhat extended observation, added to my own experience, has led me to the conviction that very much of the loss arising from abortion in our cows may be traced to the cause i have named. i feel assured the influence is even more extended than i have stated; for not only would the foetus be thrown off in its advanced stage, but also in its earlier growth, thus causing great trouble to breeders of high-bred stock, the repeated turning of cows to the bull, and at most irregular intervals. "the remedy differs in no respect from the ordinary mode of treatment, except that it compels a removal of the stock from the influence of the cause. much, however, may be done by way of prevention; and this i shall briefly notice. "it simply consists in keeping breeding cows and heifers upon land free from these seeds. grass which has been grazed during the summer, will very generally, in a humid climate, have some of this ergotized seed; but i have not observed it produced before the end of july, or early in august; and i doubt its existence, to any injurious degree, up to this time. we may, therefore, consider such ground safe up to this period. if the breeding stock are then removed to grass land which, having been mown for this operation is a guaranty against any seeds remaining, it will seldom, if ever, happen that any injury will result from the production of ergotized grass later in the season. "i will not venture to say that such will not appear in some cases where the grass has been cut early and has been followed by a rapid growth; but, at any rate, we have grazing land free from this excitant from july until september; and in the grass which has been mown late, i do not consider that there is the least fear of ergot's being again formed in that season. in this manner a farmer may keep grass land for his breeding stock entirely free from ergotized grass; and, consequently, so far as this cause is concerned, they will be free from abortion. how far young heifers may be prejudicially influenced, before they are used for breeding, by an excitement of the womb, appears to me to be a subject worthy of some attention on the part of the veterinary profession." apoplexy. this is a determination of blood to the head, causing pressure upon the brain. animals attacked with this disease are generally in a plethoric condition. the usual symptoms are _coma_ (a sleepy state), eyes protruding, respiration accelerated; finally, the animal falls, struggles, and dies. in such cases, bleeding should be resorted to at an early period; give in drink one pound of epsom-salts. black water. this is simply an exaggerated stage of the disease known as red water,--to which the reader is referred in its appropriate place,--the urine being darker in color in consequence of the admixture of venous blood. the symptoms are similar, though more acute. there is constipation at first, which is followed by diarrhoea, large quantities of blood passing away with the evacuations from the bowels; symptoms of abdominal pain are present; the loins become extremely tender; and the animal dies in a greatly prostrated condition. the treatment does not differ from that prescribed in case of red water. bronchitis. the trachea and bronchial tubes are frequently the seat of inflammation, especially in the spring of the year,--the symptoms of which are often confounded with those of other pulmonary diseases. this inflammation is frequently preceded by catarrhal affections; cough is often present for a long time before the more acute symptoms are observed. bronchitis occasionally makes its appearance in an epizoötic form. _symptoms._--a peculiarly anxious expression of the countenance will be observed; respiration laborious; a husky, wheezing, painful cough; on placing the ear to the windpipe a sonorous _râle_ is heard; symptomatic fever also prevails to a greater or less extent. _treatment._--counter-irritation should be early resorted to; strong mustard, mixed with equal parts of spirits of hartshorn and water, and made into a thin paste, should be applied all along the neck, over the windpipe, and to the sides, and should be well rubbed in; or, the tincture of cantharides, with ten drops of castor-oil to each ounce, applied in the same manner as the former, will be found equally effective. give internally ten drops of fleming's tincture of aconite every four hours, until five or six doses have been given; after which give one of the following powders twice a day: nitrate of potash, one ounce; barbadoes aloes, one ounce; jamaica ginger, half an ounce; pulverized-gentian root, one ounce; mix and divide into eight powders. if necessary a pound of salts may be given. consumption this affection--technically known as _phthisis pulmonalis_--is the termination of chronic disease of the lungs. these organs become filled with many little cysts, or sacks, containing a yellowish or yellowish-white fluid, which in time is hardened, producing a condition of the lungs known as tuberculous. these tubercles in turn undergo another change, becoming soft in the centre and gradually involving the whole of the hardened parts, which, uniting with adjoining ones, soon forms cysts of considerable size. these cysts are known as abscesses. no treatment will be of much service here. it is, therefore, better, if the animal is not too poor in flesh, to have it slaughtered. coryza in the spring, and late in the fall, catarrhal affections are quite common, occurring frequently in a epizoötic form. coryza, or nasal catarrh,--commonly called a cold in the head,--is not very common among cows. as its name implies, it is a local disease, confined to the lining membrane of the nose; and, consequently, the general system is not usually disturbed. _symptoms._--the animal will be observed to sneeze; the schneiderian membrane (membrane of the nose) is heightened in color; cough sometimes accompanies; there is also a muco-purulent discharge from the nose. neglect to attend to these early symptoms frequently occasions disease of a more serious nature; in fact, coryza may be regarded as the forerunner of all epizoötic pulmonary disorders. [illustration: a chat on the road.] _treatment._--the animal should be kept on a low diet for a few days; the nostrils occasionally steamed, and one of the following powders given night and morning, which, in most cases, will be all the medicine required: nitrate of potassa, one ounce; digitalis leaves pulverized and tartrate of antimony, of each one drachm; sulphate of copper, two drachms; mix, and divide into eight powders. should the disease prove obstinate, give for two or three days two ounces of epsom-salts at a dose, dissolved in water, three times a day. cow-pox. two varieties of sore teats occur in the cow, in the form of pustular eruptions. they first appear as small vesicles containing a purulent matter, and subsequently assume a scabby appearance, or small ulcers remain, which often prove troublesome to heal. this latter is the cow-pox, from which jenner derived the vaccine matter. _treatment._--foment the teats well with warm water and castile-soap; after which, wipe the bag dry, and dress with citrine ointment. the preparations of iodine have also been recommended, and they are very serviceable. diarrhoea. cattle are frequently subject to this disease, particularly in the spring of the year when the grass is young and soft. occasionally it assumes a very obstinate form in consequence of the imperfect secretion of gastric juice; the _fæces_ are thin, watery, and fetid, followed by very great prostration of the animal. the symptoms of diarrhoea are too well known to require any detailed description. _treatment._--if in a mild form, the diet should be low; give two ounces of epsom-salts, twice a day. in a more obstinate form, give two drachms of carbonate of soda in the food. oak-bark tea will be found very useful in these cases; or one of the following powders, twice a day, will be found very advantageous: pulverized opium and catechu, each one and a half ounces; prepared chalk, one drachm; to be given in the feed. calves are particularly subject to this disease, and it often proves fatal to them. it sometimes assumes an epizoötic form, when it is generally of a mild character. so long as the calf is lively and feeds well, the farmer should entertain no fear for him; but if he mopes about, refuses his food, ceases to ruminate, wastes in flesh, passes mucus and blood with the _fæces_, and exhibits symptoms of pain, the case is a dangerous one. in such an emergency, lose no time, but give two or three ounces of castor-oil with flour-gruel, or two ounces of salts at a dose, followed with small draughts of oak-bark tea; or give, twice a day, one of the following powders: pulverized catechu, opium, and jamaca ginger, of each half an ounce; prepared chalk, one ounce; mix, and divide into twelve powders. bran washes, green food, and flour-gruel should be given, with plenty of salt. dysentery this disease is very frequently confounded with the foregoing. a distinction, however, exists,--since inflammation appears in this disease, while it is absent in the former. in this affection, inflammation of the large intestines takes place, which is attended with diarrhoea. the _fæces_ are covered with blood; the animal rapidly becomes prostrated, and death frequently comes to his relief. youatt says: "it is, however, with dysentery that the practitioner is most loth to cope,--a disease that betrays thousands of cattle. this, also, may be either acute or chronic. its causes are too often buried in obscurity, and its premonitory symptoms are disregarded or unknown. there appears to be a strong predisposition in cattle to take on this disease. it seems to be the winding-up of many serious complaints, and the foundation of it is sometimes laid by those that appear to be of the most trifling nature. it is that in cattle which glanders and farcy are in the horse,--the breaking up of the constitution. "dysentery may be a symptom and concomitant of other diseases. it is one of the most fearful characteristics of murrain; it is the destructive accompaniment, or consequence, of phthisis. it is produced by the sudden disappearance of a cutaneous eruption; it follows the cessation of chronic hoose; it is the consequence of the natural or artificial suspension of every secretion. were any secretion to be particularly selected, the repression of which would produce dysentery, it would be that of the milk. how often does the farmer observe that no sooner does a milch cow cease her usual supply of milk than she begins to purge! there may not appear to be any thing else the matter with her; but she purges, and, in the majority of cases, that purging is fatal. "it may, sometimes, however, be traced to sufficient causes, exclusive of previous disease. unwholesome food--exposure to cold--neglect at the time of calving--low and marshy situations--the feeding in meadows that have been flooded, where it is peculiarly fatal--the grazing (according to mr. leigh, and our experience confirms his statement) upon the clays lying over the blue lias rock--the neighborhood of woods and of half-stagnant rivers--the continuation of unusually sultry weather--overwork, and all the causes of acute dysentery, may produce that of a chronic nature; an acute dysentery--neglected, or badly, or even most skillfully treated--may degenerate into an incurable chronic affection. half starve a cow, or over-feed her, milk her to exhaustion, or dry her milk too rapidly--and dysentery may follow. "the following will, probably, be the order of the symptoms, if they are carefully observed: there will be a little dullness or anxiety of countenance, the muzzle becoming short or contracted; a slight shrinking when the loins are pressed upon; the skin a little harsh and dry; the hair a little rough; there will be a slight degree of uneasiness and shivering that scarcely attracts attention; then--except it be the degeneracy of acute into chronic dysentery--constipation may be perceived. it will be to a certain extent, obstinate; the excrement will voided with pain; it will be dry, hard, and expelled in small quantities. in other cases, perhaps, purging will be present from the beginning; the animal will be tormented with _tenesmus_, or frequent desire to void its excrement, and that act attended by straining and pain, by soreness about the _anus_, and protrusion of the _rectum_, and sometimes by severe colicky spasms. in many cases, however, and in those of a chronic form, few of these distressing symptoms are observed, even at the commencement of the disease; but the animal voids her _fæces_ oftener than it is natural that she should, and they are more fluid than in a state of health; while at the same time she loses her appetite and spirits and condition, and is evidently wasting away." _treatment._--give one drachm of the extract of belladonna, three times a day, dissolved in water; or calomel and powdered opium, of each one drachm three times daily. as soon as the inflammatory stage passes by, give one of the following three times daily, in their gruel: nitrate of potash pulverized, gentian-root pulverized, of each one ounce; pulverized jamaica ginger, one half an ounce; pulverized caraway, or anise-seed, six drachms. a bottle of porter given once or twice a day, will be found of very great advantage. enteritis. this is an inflammation of the external or internal coat of the intestines, sometimes attended with violent purging, especially when it is confined to the internal coats. oxen in good condition are more subject to this disease than are cows. it most frequently occurs in dry, hot weather. it is sudden in its attacks, and often fatal in its termination. _symptoms._--the animal is dull, and not disposed to move about; the muzzle is dry, and the coat staring; the animal yields, on pressure of the _loins_; a weak, staggering gait, when forced to move; respiration hurried; pulse accelerated but small; eyes red, full and fiery; head protruding; mouth, ears, and horns hot; appetite bad; rumination ceases; the bowels become constipated; the animal moans continually, and froths at the mouth. these symptoms violently increase as the disease advances. the animal becomes more depressed and feeble, grinds his teeth, and appears half unconscious, and dies in convulsions. of the causes of this disease, youatt, who is almost the only authority we have upon this subject, says: "it seems occasionally to be epidemic; for several instances of it occur, of the same character, and in the same district. m. cruzel gives an illustration of this in his description of the disease that destroyed so many cattle, in the years 1826 to 1827, in the department _de la nievre_. out of two hundred and eighteen cattle belonging to three farmers, one hundred and thirteen were attacked by this disease, and eighty-three of them died. one farmer in a neighboring district had nineteen head of cattle, all of which sickened, but only three were lost. these were unusually hot summers. the upland pasture was burnt up, or what remained of it was rendered unusually stimulating; and the acrid plants of the marshes and low grounds acquired additional deleterious agency. "when isolated cases occur, they may generally be attributed to mismanagement. exposure to cold, or the drinking of cold water when overheated with work; too hard work in sultry weather; the use of water stagnant, impure, or containing any considerable quantity of metallic salts; the sudden revulsion of some cutaneous eruption; the crowding of animals into a confined place; too luxuriant and stimulating food generally; and the mildewed and unwholesome food on which cattle are too often kept, are fruitful sources of this complaint." _treatment._--in the early stage of the disease, give an active purge, and follow it with ten drops of fleming's tincture of aconite, four times daily, for two days; then give drachm doses of the extract of belladonna; give no food for twenty-four or forty-eight hours, according to circumstances. bleeding, if done early, is often beneficial. counter-irritants to the belly are also recommended; the best are mustard, hartshorn, and water, mixed together--or tincture of cantharides, with one drachm of croton-oil added to every ounce. epizoötics. diseases of this class have the same relation to the inferior animals that epidemic diseases have to man. of course, they assume a very pestilential character. scarcely a year passes away without diseases of this nature making their appearance in some parts of the world. they occur at all seasons of the year, but more generally prevail in the spring and fall. the period of their duration varies from months to years. they are, at times, mild in their attacks, and yield readily to proper treatment; at other times, they become painful pestilences, destroying every thing in their course. the causes are generally sought for in some peculiar condition of the atmosphere. the use of the milk and flesh of diseased cattle has frequently been productive of malignant diseases in the human family. silius italicus describes a fearful epizoötic, which first attacked the dog, then the feathered biped, then horses, and cattle, and, last of all, the human being. "on mules and dogs the infection first began, and, last, the vengeful arrows fixed in man." epizoötics, occurring in rats, cats, dogs, horses, and cattle, which were followed in the succeeding years by more fearful ones which attacked the human family, are numerously recorded. these scourges have appeared in all ages of the world; but, as time and space will not allow our entering upon an extended consideration of them,--however interesting they might be to the general reader,--we shall content ourselves by quoting, somewhat in brief, from the lectures of the late william youatt on these fatal maladies:-"in the year 801, and at the commencement of the reign of charlemagne, an epidemic disease devastated a great portion of his dominions. this was attributed to the villainy of the duke of benevento, who was said to have employed a great many persons in scattering an enchanted powder over the fields, which destroyed both the cattle and the food of the cattle. m. paulet seems inclined to give full credence to this, and says that history offers many proofs of this destructive and diabolical practice. he affirms that many persons were punished in germany, france, and, particularly, at toulouse, for the commission of this crime. several of the suspected agents of these atrocities were put to the torture and made full confession of their crime. "of the occurrence of these diseases from the year 800 to 1316,--an interval of mental darkness, and of horrors and calamities of every kind,--history records twenty cases, more or less destructive, and extending, with greater or less devastation, over france and germany, italy and england. of these twenty, four date their origin from an excessive moisture in the air, accompanied by almost continual rains, and flooding the country to a considerable extent. one was supposed to be the consequence of long-continued drought and excessive heat; one was traced to the influence of an eclipse of the sun; another, to a comet; and a fourth, to a most unusually stormy winter. the reader will have the kindness to remember that we are here expressing the opinions of the writers of the day, and by no means, our own belief of the matter. "of the four which trace their origin to extreme wet and its consequences, the first occurred in france, in 820, after a long continuance of rain; and it was equally fatal to men and cattle. the second, which was equally fatal to both, appeared in lorraine, in 889. the third broke out among the cavalry of the army of arnoul, in its passage over the alps, on its return to italy. the fourth pervaded the whole of england in 1125, and was equally fatal to the biped and the quadruped. "that which followed excessive heat and drought, was generally prevalent throughout europe, but especially so in germany. it attacked oxen, sheep, and pigs. it appeared in 994, and lasted six months. "the one which was attributed to the comet, and which principally attacked cattle, appeared in france in 943 almost every animal perished. "another, that was supposed to be connected with an eclipse of the sun, was prevalent throughout the greater part of germany, among men and animals, in 989. "the disease, which was the consequence of a cold and boisterous winter, was principally prevalent in france, in 887, and committed sad ravages among the herds of cattle and sheep. "of the twelve others, of which, authors do not indicate the cause, the first was in france, in 810, and principally among cattle. the second was also in france, in 850, and almost depopulated the country of cattle. the third, in 868, was common to all animals in france. the fourth, in 870, was in the same country, and caused severe loss among cattle. the fifth prevailed on the rhine and in germany, and destroyed an almost incalculable number of cattle. the sixth attacked the horses of the army of arnoul in lorraine, in 888. the seventh, in 940, destroyed a vast number of cattle in france, italy, and germany. the eighth and ninth were in france, in 941 and 942, and almost all the cattle in the country perished. the tenth pestilence broke out in england, in the year 1041, and frightful was its devastation among all animals, and, particularly, horned cattle. the eleventh also devastated our country, in 1103, and the ravages were dreadful. the twelfth was chiefly fatal in germany, and particularly in gueldres, in 1149. "these twenty pestilences occurred in the space of 506 years. five or six of them were most prevalent among cattle; two were almost confined to horses; twelve included, to a greater or less degree, almost every species of quadrupeds; and four extended to the human being. among these the ravages of eight were most destructive in france; as many in germany; and four in italy and england. "as far as we have hitherto proceeded, it will also appear that cattle are more subject to these diseases than any other species of domesticated animals, and that the pestilence is always most fearful among them. it is also evident that the maladies which proceed from cold or humidity are more frequent in the temperate and southern parts of europe than those which depend upon drought, or almost any other cause. "the malady lingers in different countries, in proportion to its want of power to accomplish at once all its devastation. "after this time, there are few satisfactory accounts of these diseases for more than five centuries. we only know that, occasionally suspending their ravages,--or, rather, visiting new districts when they had ceased to desolate others--they have continued to be objects of terror and instruments of devastation, even unto the present day; and it is only within a few years that they have been really understood, and have become, to a certain degree, manageable." in the united states, epizoötic diseases have been of frequent occurrence; but, owing to the want of properly qualified veterinary surgeons, they have not, until within a very recent period, been properly described or understood. the day however, is fast approaching when this void will be filled, and when epizoötic and other diseases will be correctly noted and recorded. the necessity for this must have been forcibly impressed upon the minds of the inhabitants of our country from the experience of the last ten or twelve years. respecting the late epizoötic among cattle in portage county, ohio, william pierce, v.s., of ravenna, thus describes the symptoms as they appeared, in a letter to the author: "a highly-colored appearance of the sclerotic coat of the eye, also of the _conjunctiva_ (a lining membrane of the eyelid) and the schneiderian membrane of the nose; a high animal heat about the head and horns; a highly inflammatory condition of the blood; contraction of all the abdominal viscera; hurried respiration; great prostration and nervous debility; lameness; followed by gangrene of the extremity of the tail, and the hind-feet; terminating in mortification and death." mr. pierce is convinced that these symptoms are produced by the continued use of the ergot, or spur of the june grass,--the effects being similar to those produced upon the human family by long-continued use of ergot of rye. this disease assumes both an acute and chronic form. the same gentleman also says: "ordinary observers, as well as those who claim to be scientific, have entertained very conflicting opinions as to its general character; some regarding it as epizoötic, others as contagious; some attributing it to atmospheric influence, others to foulings in the stable or yard. others, again, attribute it to freezing of the feet in winter. cattle-doctors in a majority of cases, fail to cure it. i have, however, by a simple course of treatment, effected many signal cures. some parties are so confident of the contagious character of the disease that they refuse to drive cattle along a road where it is known to exist. they even, oftentimes, wash their boots previous to entering their barnyards, after walking over the ground where such diseased cattle have been running. "caution is both proper and commendable. i do not, however, regard it as a contagious disease, nor can it be transmitted by inoculation. the calf is carried during the progress of the disease, and delivered in apparently good health. the milk of the cow appears to be unaffected and harmless. i call this disease _sphacial fever_, or _gangrenous fever_. [illustration: the mad bull.] "the ergot, or spur of the hay, is confined to the june grass, as far as my observation extends; owing, probably, to its early maturity. most other kinds of grass are cut before the seeds have matured sufficiently to produce the spur. i was suspicious of the foulness of the feed before i examined any hay, and have found the spur in the hay wherever the disease is found. "mr. sanford, of edinburgh, ohio, purchased one half of a mow of hay from mr. bassett, of randolph, which was removed to his farm in randolph, eight miles distant. of this hay, mr. sanford fed eleven cows some six or eight weeks. mr. bassett had been feeding the same to four cows. at about the same time, both heads began to show lameness. i visited mr. s. after he had lost six cows, and examined the remaining five, four of which were lame and the other showed symptoms of the disease. he had two other cows, one of which was loaned to a neighbor, and the other was fed upon different hay, for convenience. the loaned cow was returned about the first of march,--the two then running with the ailing ones until the 24th of april, when i saw them sound and in good health. "i then visited mr. bassett's stock, which i found infected with the same disease,--he having lost one, and the remaining three being lame, and much debilitated. the hoofs were sloughing off. some of the same hay remained in the snow, which, upon examination, exhibited an abundance of the spur. upon inquiry, i found that no such disease existed between the two farms, or in the neighborhood of either mr. s. or mr. b. the peculiarity of this circumstance at once swept away the last vestige of doubt from my mind. mr. e. chapman, of rootstown, accompanied me, and can vouch for the correctness of these statements. "he hooted at my opinions, asserting that he understood the disease, and that it was caused by the freezing of the feet. he has since, however, abandoned that idea, and honestly 'acknowledged the corn.' this ergot is regarded by some as a parasitic fungus, formed in other grains, an abundant vegeto-animal substance, and much disposed to putrefaction. we appear to be in the dark regarding its real composition. the little which has been written upon the subject, appears to be founded upon hypothesis, and that the most obscure. the articles to which i refer may differ in quality or property to a considerable extent, and we may forever remain in the dark, unless chemical investigation be instituted. "in this particular disease, there appears to be singularity in the symptoms through all its various stages, which is likely to originate in the peculiarity of the cause which produces them. the effects and symptoms arising from the continued use of the ergot of rye, as manifested in the human system, have been but briefly hinted at by authors, and, probably, some of them are only reasonable conjectures. all they say is, that it produces violent headache, spaculation in the extremities, and death. hitherto, its effects upon the inferior animal have been subjected to no investigation, and its peculiarity in the symptoms, differing from like phenomena by other causes, may yet be demonstrated. i am not alone in my opinion of this disease. i have taken counsel of those whose judgment cannot be questioned. whatever difference of opinion exists is attributable to a want of investigation, and it will continue to exist until this singular phenomenon is clearly accounted for. every opinion should be thoroughly criticized till facts are obtained. every man's opinion is sacred to himself, but we should yield to conviction. "two classes of this disease are exhibited: one, of irritation, and the other, of debility; one, an acute, the other, a chronic form. the point at which it assumes the chronic form is between congestion and gangrene. by close observation we can discover these to be different and higher degrees of the same disease. all subsequent degrees are dependent upon the first. "the first symptom, or degree, is, probably, an attack upon the systematic circulation, produced by a certain medicinal and deleterious property existing in the ergot, and communicated to the blood through the absorption of the tongue. this is more evident from the fact that the digestive organs retain their normal condition till the last stages of the chronic form. the blood in the first two stages is healthy, and the peculiar influence is only apparent in the subsequent stages; as evidenced by the fact that the muscles and general good appearance, as well as life itself, last longer than could be possible, if this deleterious influence were exhausted upon the digestive organs and the blood, in its first stages. and, as we suppose that fever and congestion constitute an attack upon the red blood, which is exhibited by hurried pulsation, we might rationally infer that the next degree would be gangrene of the globule, causing sloughing, the same as if it were carried to the muscles, or surface. this sloughing of the globule would be the same as if exhibited on any other part of the organization, for the fibrin is identical with muscle, as albumen is identical with the white of an egg; and since congestion is the forerunner of gangrene at the extremities, or on the surface, so fever and quick pulsation are the forerunners of congestion of the blood. gangrene cannot ensue without obstruction in the blood-vessels; and congestion cannot take place without obstruction in that which sustains the globule. as gangrene, then, is the first stage of decomposition of animal matter, so is congestion the first stage of decomposition of the globule; and as mortification is death in the organized body, so is congestion death in the organized globule. "it appears evident that this disease, in all its forms and degrees of intensity, seeks vent or release; in other words, nature conflicting with it, throws it off its track, or balance, and offers means of escape, or shows it a door by which it may make its exit. in the first stage of the disease, the dermoid (skin) tissues make the effort. in the inflammatory, the serous, and the congestive, the mucous gangrene seeks vent; if obtained, mortification is prevented; if not, mortification directly supervenes, and death terminates the case. "in the case to which i refer, observation confirms my opinion that absolute mortification without vent determines the gangrene of the blood, and is hardly curable; but that gangrene's finding vent determines it to be curable, and the recovery highly probable." epizoötic catarrh. catarrh frequently assumes an epizoötic form of a very virulent character, originating spontaneously and extending over a large section of country at or about the same time. a cold spring succeeding a mild winter, is peculiarly productive of malignant catarrh. this is one of the most distressing and fatal diseases to which cattle are subject. _symptoms._--the animal appears dull, and unwilling to move about, staggering when forced to do so; obstinate costiveness is usually one of the earliest symptoms, succeeded by diarrhoea, which is equally difficult of management; sometimes, however, diarrhoea is present from the first; the animal loses flesh rapidly; the coat is staring; appetite is lost; tumors form about the head, neck, back, and joints, which appear to be filled with air, and upon pressure cause a crepitating sound; saliva flows from the mouth, becoming very fetid as the disease progresses. the animal always dies of putrefaction. _treatment._--this disease should be treated early, or not at all. good nursing is very essential. when costiveness is present, give barbadoes aloes, one ounce; croton-oil, ten drops; mix together; or give one pint of linseed-oil, to which add from ten to twenty drops of castor-oil. if the bowels are not open in twenty-four hours, give four ounces of sulphate of magnesia every six hours until they are opened. follow this with tincture of aconite, ten drops in water, every four hours, until the fever has abated. bleeding has been recommended by some writers; but the author has failed to experience any benefit from resorting to it, but, on the contrary, has seen much injury result from the use--or, rather, the abuse--of the lancet. he is, indeed, inclined to attribute much of the fatality attending this disease to indiscriminate blood-letting. when much debility exists, the animal should be sustained by tonics and stimulants. one ounce of nitric ether and half an ounce of tincture of opium, given in a little water, will be found beneficial. it should be given twice a day. pulverized gentian-root, one ounce; jamaica ginger, half an ounce; pulverized cloves, half an ounce; mixed, and divided into four powders, one to be given at night and at morning; will be found useful, in place of the opium and ether. fardel. this disease is properly known by the name of clue-bound. the manyplus, or omasum (third stomach), frequently becomes so choked up with food that it is hard and dry, and the operation of the digestive organs is very seriously impaired. the animal eats voraciously, for a time, but stops suddenly and trembles; the countenance assumes a peculiarly haggard appearance; there is a wild expression of the eye; a foaming at the mouth; a tendency to pitch forward, and at times a falling head-foremost to the ground. occasionally, the symptoms are very active, speedily terminating in death. there are few diseases of a constitutional character in which the stomach is not, more or less, sympathetically involved. "toward the end of september, 1746, a great number of cows died at osterwich, in the principality of halberstadt. lieberkuhn, a celebrated physician,--there were no veterinary surgeons at that time,--was sent to examine into the nature of the disease, which was supposed to be one of the species of murrain that was then committing such ravages among the cattle in various parts of the continent. there were none of the tumors, or pestilential buboes, that, in an earlier or later period of the malady, usually accompanied and characterized murrain; but upon inspection of the dead bodies, considerable peritoneal inflammation was found; the first and second stomachs were filled with food, but the third stomach was the palpable seat of the disease; its leaves were black and gangrened. the mass contained between the leaves was black, dry, and so hard that it could scarcely be cut with a scalpel. it intercepted the passage of the food from the first two stomachs to the fourth; and this latter stomach was empty and much inflamed. neither the heart, nor the lungs, nor the intestines exhibited any trace of disease. twelve cows were opened, and the appearances were nearly the same in all of them." _treatment._--give one and a half pounds of epsom-salts, dissolved in three pints of water; or one quart of potash, three times daily, dissolved in water, will be found useful in this disease. foul in the foot. this is caused by hard or irritating substances making their way in between the claws of the foot, causing inflammation, and sometimes ulceration, in the parts. the pasterns swell, and the animal becomes lame. the foot should be thoroughly washed, and all foreign substances removed. a pledget of tow, saturated with tar and sprinkled with powdered sulphate of copper, should be inserted between the claws. this usually requires but one or two applications. garget. this is a hard, knotty condition of the udder, which sometimes follows calving, in consequence of the sudden distention of the bag with milk; and the inflammation which supervenes causes a congealed or coagulated condition of the milk to take place, of which, if neglected, suppuration and abscesses are the result. _treatment._--let the calf suck the dam as speedily as possible, and, if the hardness is not then removed, foment the udder with warm water; after which, wipe it dry, and apply to the entire surface melted lard as hot as the animal will bear. this is, generally, all that is required, the most obstinate cases yielding to it. if abscesses form, they should be lanced. gastro-enteritis. this disease--otherwise known as wood-evil, or moor-ill--arises from eating the buds of oak, young ash, and other trees, which are of a very highly stimulating or irritating character. as the intestinal canal is liable to inflammatory action from irritant substances admitted into it, animals are found to become diseased from eating too freely of these vegetable substances. _symptoms._--loss of appetite and suspended rumination; mouth hot; skin dry; pulse from sixty to seventy; swelling and pain of the belly; obstinate constipation; fæces hard and covered with blood; urine of a strong odor, highly colored, and voided with difficulty. _treatment._--the animal should be bled, and a strong purgative administered, followed by aconite and belladonna, as in enteritis. injections of castile-soap and water should be freely used; the application of the mustard, hartshorn, and water to the belly will also be found very beneficial. hoose. this disease--known also as catarrh--is occasionally the sequence of coryza, but more frequently it arises from an impure atmosphere; consequently, in cow-houses where animals are crowded together in numbers, it is most frequently found. scanty provender, and of an inferior quality, is among the exciting causes of hoose, producing, as it does, a debilitated state of the system, which, upon exposure of the animal to cold, or wet, hastens the disorder. some breeds of cattle are peculiarly liable to this disease, which, if not arrested in its early stage, runs on, involving the lungs, and frequently terminating in consumption. of all our domestic animals, neat cattle are most subject to pulmonary diseases. this is attributable to the neglect and exposure which are far too often their lot. butchers will testify that a large portion of all cattle slaughtered have abscesses and other diseases of the lungs. _symptoms._--loss of appetite; muzzle dry; coat rough, or staring; respiration quickened; horns hot; ears, nose, and legs cold; husky cough; pulse from sixty to seventy, small and thready; bowels frequently constipated. _treatment._--give one ounce of the following powders every six hours, until the bowels are opened: barbadoes aloes, one and half ounces; nitrate of potassa, half an ounce; ginger, six drachms; mix and divide into six powders. setons in the dewlap are often of great benefit. hoove. hoove, or blown, so common, and often so speedily fatal in cattle, is the result of fermentation in the _rumen_, or paunch, in consequence of the animal's having eaten large quantities of wet grass, luxuriant clover, turnips, etc. an accumulation of gas is the result of this fermentation, which greatly disturbs the haunch and left side of the belly, causing much pain to the animal, and frequently threatening suffocation. _treatment._--drench the animal with one ounce of spirits of hartshorn in one quart of water, the object being to neutralize the gas which is present in the rumen; or, two ounces of table salt dissolved in one quart of water will be found very effectual. if these do not speedily give relief, an active purge should be given. injections of soap and water should be freely used. if the case still proves obstinate, and the life of the animal is threatened, the paunch should be punctured. for this purpose, the trochar--an instrument specially adapted--should be used; but, in the absence of an instrument, an ordinary pocket-knife may be employed, taking care not to make a large opening. the proper point to operate is midway between the last rib and the prominent point of the hip-bone, about twelve inches from the centre of the back or loins. few cases have a fatal termination where this operation has been properly performed. hydatids. worms in the brain occasionally occur, causing great uneasiness to the animal and generally proving fatal. the symptoms are, loss of appetite; suspended rumination; a fevered condition of the system; horns and ears hot; respiration disturbed; coat staring, etc. no course of treatment will prove efficacious in this disease. pressure on the brain may occur from an accumulation of water, tumors, bruises, etc., in the cranial case. in either case, the same effects are produced as are observed in apoplexy. inflammation of the bladder. inflammation of the bladder generally accompanies inflammation of the kidneys, though it is sometimes found disconnected and alone. it is occasionally caused by calculous concretions in the bladder,--which should be removed,--causing very acute abdominal pain to the animal. she makes frequent efforts to stale, passing but a few drops of urine at a time. the pulse is full and rapid; mouth clammy; nose dry; eyes bloodshot; appetite lost; moaning, and walking with a staggering gait. _treatment._--inject into the bladder one quart of tepid water, and from one to two ounces of tincture of opium mixed together. give internally one of the following powders every hour until relieved; nitrate of potassa, one ounce; tartrate of antimony, and pulverized digitalis leaves, each one drachm; mix, and divide into six powders. mucilaginous draughts should be freely given. rupture of the bladder sometimes occurs, but there are no symptoms by which it may be known; and, if there were, no service could be rendered in the way of repairing the injury; the animal must die. inflammation of the haw. the ox, like the horse, has a membrane of semilunar form in the inner corner of the eye, which is capable of being thrown over the entire eyeball, for the purpose of cleansing the eye from any foreign substance which may get into it. this membrane is commonly called the haw, and is susceptible of attacks of inflammation, which cause it to swell, frequently even closing up the eye. _treatment._--give a dose of physic, and, if the animal is plethoric, extract a little blood from the vein on the same side as the affected eye. apply to the eye either of the following washes: tincture of opium, one ounce; rain-water, one pint; or, tincture of aconite, one drachm, to one pint of water. bathe two or three times a day. inflammation of the kidneys. this disease--sometimes called nephritis--occurs occasionally in cattle in consequence of their eating bad or unwholesome food, or of the abuse of diuretics, etc. the symptoms are very insidious in their approach. the loins are very tender upon pressure; the urine is voided in small quantities. as the disease advances, the symptoms become more marked and acute. the animal is dull, and feeds daintily; the evacuation of urine is attended with increased pain, and the urine is highly colored and bloody; the nose is dry; the horns, ears, and extremities are cold; respiration hurried; the pulse full, hard, and throbbing. _treatment._--give one pint of linseed-oil and ten drops of castor-oil, mixed together; follow this with small doses of salts once a day, for three or four days; give injections of water, one half a gallon to two ounces of tincture of arnica. mustard applications to the loins are also very useful. inflammation of the liver. diseases of the liver are of very common occurrence,--a fact with which all beef-butchers are familiar. perhaps no organ in the animal economy is so liable to disease. the obscurity of the symptoms and the good condition of the animal prevent its discovery, as a general thing, during its lifetime. when, however, the disease assumes an active form,--known as the yellows, jaundice, or inflammation of the liver,--the symptoms are more readily detected. _symptoms._--a yellowish color of the eye will be observed; skin, urine, etc., highly colored; soreness, on pressure, on the right side; loss of appetite; dullness; constipation of the bowels, etc. _treatment._--calomel is the most reliable medicine known to practitioners for diseases of the liver. its abuse, however, has brought it into disrepute. yet, as with ordinary care it may be advantageously used, we will prescribe it as that upon which the most dependence is to be placed, and in doing so, will endeavor to have it used safely. bleeding has been recommended: but the author has never found any benefit resulting. give epsom-salts, in doses of four ounces each, every night, with one scruple of calomel, until the animal is relieved. mustard and water should be frequently applied to the right side, and well rubbed in. laryngitis. this disease is of rare occurrence in cattle. in it, the mucous membrane lining the larynx is in a very irritable condition; the least pressure upon the parts affected causes intensely excruciating pain; the respiration becomes quick, painful, and laborious; the animal often appears to be hungry, yet does not eat much, in consequence of the pain occasioned by the act of swallowing. _treatment._--apply to the throat externally strong mustard, mixed, with equal parts of aqua ammonia and water, to a thin paste, every hour, until it produces an effect upon the skin; sponging the parts each time with warm water before applying the mustard. the animal should not be bled. give upon the tongue, or in drink, half-drachm doses of nitrate of potassa, every three or four hours, until relief is obtained. if suffocation threatens, the operation of tracheotomy is the only resort. [illustration: an aberdeenshire polled bull.] cloths saturated with cold water, wrapped around the neck so as to cover the larynx, frequently afford relief. a purgative will also be found useful. lice. cattle are very subject to lice, particularly when they are neglected, half-starved, and in poor condition. good care and good feeding--in connection with the treatment recommended in mange, to which the reader is referred--will comprise all that is requisite. mange. mange, or leprosy, is one of the most unpleasant and difficult diseases to manage of all the ailments to which cattle are subject requiring the nicest care and attention to render it easy of cure. an animal badly nursed will not, under the most skillful treatment, quickly recover. its causes are in the main, due to poor food, which produces a debilitated condition of the system, and in connection with a want of cleanliness, causes a development of the _acari_, or minute insects, exciting very great irritation upon the skin and causing the cow to rub herself against every object with which she comes in contact. the hair falls off; a scurfy appearance of the skin is perceptible; and the animal is poor in condition and in milk. the great trouble in treating this disease springs from its contagious character; for, no sooner is the animal, oftentimes, once free from the _acari_ than it comes in contact with some object against which it has previously been rubbing, when the _acari_ which were left upon that object are again brought in contact with the animal, and the disease is reproduced. if, immediately after the proper applications are made, the animal is removed to other quarters, and not allowed to return to the former ones for six or eight weeks, there is, generally speaking, but little trouble in treating the disease. take the animal upon a warm, sunny day, and with a scrubbing-brush cleanse the skin thoroughly with castile-soap and water; when dry, apply in the same manner the following mixture; white hellebore, one ounce; sulphur flower, three ounces; gas-water, one quart; mix all well together. one or two applications are, generally, all that will be required. give internally one of the following powders in the feed, night and morning: flowers of sulphur, two ounces; black antimony, one ounce; nitrate of potassa, one ounce; mix, and divide into eight powders. murrain. this is one of the most malignant diseases to which cattle are liable. fortunately, however, true murrain is comparatively rare in this great stock-raising country. the entire system seems to partake of the disease. the first indication of its approach is a feverish condition of the system, attended with a frequent and painful cough; the pulse is small, hard, and rapid. as the disease advances, the respiration becomes disturbed; the flanks heave; vesicular eruption is observed upon the teats, mouth, and feet; the horns are cold; the animal is sometimes lame; constipation and, sometimes, diarrhoea are accompanying symptoms; _fæces_ black and fetid; the eyes weep and become much swollen; great tenderness along the spine; a brown or bloody discharge from the nose and mouth; the animal moans incessantly, grinds his teeth, rarely lies down, but to get up again quickly; finally, the breath becomes very offensive; tumors make their appearance in various parts of the body, which, in favorable cases, suppurate, and discharge a fetid matter. _treatment._--give one fourth of a pound of epsom-salts, with one drachm of jamaica ginger, twice a day, for two or three days. a bottle of porter, twice a day, will be found serviceable. very little medicine is required internally in this disease, but much depends upon good nursing. external applications are chiefly to be depended upon. a solution of chloride of lime should be applied to the eruptions, or a solution of the chloride of zinc, twenty grains to an ounce of water; or, of sulphate of zinc, two drachms to a pint of water; or pulverized charcoal applied to the parts will be found useful. navel-ill. inflammation of the navel in calves occasionally occurs, causing redness, pain, and sudden swelling in the part affected. this disease, if not promptly attended to, speedily carries off the creature. _treatment._--foment the part well with warm hop-tea; after which, the application of a cloth, well saturated with lead-water and secured by bandages, should be applied. internally, doses of epsom-salts, of two ounces each, dissolved in half a pint of water, should be given until the bowels are acted upon. after the inflammation has subsided, to counteract the weakness which may follow, give a bottle of porter two or three times a day. obstructions in the oesophagus. choking in cattle is of common occurrence, in consequence of turnips, potatoes, carrots, or other hard substances, becoming lodged in the oesophagus, or gullet. these obstructions can sometimes be removed by careful manipulations with the hand; but, where this can not be accomplished, the flexible probang should be employed. this is a long india-rubber tube, with a whalebone stillet running through it, so as to stiffen it when in use. this instrument is passed down the animal's throat, and the offending substance is thus pushed down into the stomach. open joints. opening of the joint generally results from accidents, from puncturing with sharp substances, from kicks, blows, etc. these injuries cause considerable nervous irritation in the system, and sometimes cause lock-jaw and death. _treatment._--close up the wound as speedily as possible. the firing-iron will sometimes answer the purpose very well. the author depends more upon the application of collodion--as recommended in his work upon "the horse and his diseases" for the same trouble--than upon any other remedy. it requires care in its application, in order to make it adhere firmly. shoemakers'-wax, melted and applied, answers a very good purpose. parturition. in natural labor--as has been suggested in a former part of this work--the aid of man is rarely required in bringing away the calf. but it not infrequently happens that, from malformation or wrong presentation, our assistance is required in order to deliver the animal. the brute force, which has been far too often heretofore resorted to, should no longer be tolerated, since the lives of many valuable animals have been sacrificed by such treatment. very often, by gentle manipulation with the greased hand, the womb can be so dilated as to afford a comparatively easy exit for the _foetus_. if, however, the calf is presented wrong, it must be pushed back and placed in its proper position, if possible. in natural labor, the fore-legs, with the head lying between them, are presented; in which position--unless deformity, either in the _pelvis_ of the cow, or in the _foetus_, exists--the calf is passed with little difficulty, and without assistance. it sometimes happens that the head of the foetus is turned backward. when this happens, the attendant should at once strip himself to the waist, bathe his arms, and hands with a little sweet-oil, or lard, and introduce them into the _vagina_, placing a cord around both fore-feet, and then, pushing them back, search for the head, which is to be brought forward to its proper position. the feet are next to be brought up with it. no force should be used, except when the cow herself makes the effort to expel the calf; otherwise, more harm than good may be done. a case of this kind recently occurred in the author's practice, being the third within a year. the subject was a cow belonging to william hance, esq., of bordentown, new jersey. after she had been in labor for some twenty hours, he was called upon to see her. upon inquiry, he found that several persons had been trying, without success, to relieve her. she was very much prostrated, and would, doubtless, have died within two or three hours, had no relief been afforded. the legs of the _foetus_ protruded as far as the knees; the head was turned backward, and with the body, pressed firmly into the _vagina_, so that it was impossible to return it, or to bring the head forward. the operation of embryotomy was, therefore, at once performed, by cutting away the right shoulder, which enabled the operator, with the aid of his appropriate hooks, to bring the head forward, when the calf came away without further trouble,--the whole operation not requiring fifteen minutes. the _uterus_ was then washed out, and the animal placed in as comfortable a position as possible, and a stimulating draught given, composed of two ounces of nitric ether, one ounce of tincture of opium, and a half pint of water. this was followed with a few doses of fleming's tincture of aconite, ten drops in a little water, every few hours. in a few days the animal had entirely recovered. occasionally, the head comes first, or the head and one leg. in such cases, a cord should be slipped around the jaw and leg, and these then pushed back, so as to allow the other leg to be brought up. when this cannot be done, the _foetus_ can, in most cases, be removed in the original position. breech, side, back, and other presentations sometimes occur; in all of which instances, the _foetus_ must be turned in such a position that it can be brought away with as little trouble as possible. when this cannot be accomplished, the only resort is embryotomy, or cutting up of the _foetus_, which operation can only be safely performed by the qualified veterinary surgeon. since writing the above, another case has occurred in the author's practice. the cow--belonging to samuel barton, esq., near bordentown, new jersey--had been in labor some eighteen hours; upon an examination of the animal, the calf was found to be very much deformed, presenting backwards,--one of the hind-legs having been pulled off by the person or persons assisting her previous to the author's arrival. finding it impossible to deliver her in the usual way, embryotomy was in this instance employed. by this means, after taking out the intestines, lungs, etc., of the _foetus_, and cutting away its hind-quarters, the fore-parts were brought away. the head presented a singular appearance; the under jaw was so twisted as to bring the front teeth on the side of the face; the spinal column or back-bone, was turned twice around, resembling a spiral string; the front legs were over the back; the ribs were much contorted; the hind-parts were as much deformed; and, taken altogether, the deformity was the most singular which has been brought under the author's observation. free martins.--it has long been supposed by stockbreeders, that if a cow produce twins, one of which is a male and the other a female, the female is incapable of producing young, but that the male may be a useful animal for breeding purposes. many instances have occurred when the twin sister of a bull has never shown the least desire for the male. this indifference to sexual commerce arises, doubtless, from the animal's being but imperfectly developed in the organs of generation. this fact has been established by the investigations of mr. john hunter, who had three of these animals slaughtered for anatomical examination. the result is thus reported: "the external parts were rather smaller than is customary in the cow. the _vagina_ passed on, as in the cow, to the opening of the _urethra_, and then it began to contract into a small canal, which passed on into the division of the _uterus_ into the two horns; each horn passed along the edge of the broad ligament laterally toward the _ovaria_. "at the termination of these horns were placed both the ovaries and the testicles. both were nearly of the same size, which was about as large as a small nutmeg. to the _ovaria_, i could not find any fallopian tube. "to the testicles were _vasa deferentia_, but they were imperfect. the left one did not come near the testicle; the right one only came close to it, but did not terminate in the body called the _epididymis_. they were both pervious and opened into the _vagina_, near the opening of the _urethra_. "on the posterior surface of the bladder, or between the _uterus_ and the bladder, were the two bags, called _vesiculæ seminales_ in the male, but much smaller than they are in the bull. the ducts opened along with the _vasa deferentia_. this animal, then, had a mixture of all the parts, but all of them were imperfect." well-authenticated cases have, however, occurred where the female has bred, and the offspring proved to be good milkers. there are several instances on record of cows' giving birth to three, four, and even five calves at a time. there were on exhibition, in 1862, at bordentown, new jersey, three free martins, two sisters and a brother, which were beautiful animals. these were from a cow belonging to mr. joab mershon, residing on biles island, situated in the delaware river, a short distance above bordentown. they were calved november 1st, 1858, and were therefore nearly four years of age. they had never shown the least desire for copulation. their aggregate weight was 4300 pounds. we extract the following from the london veterinarian, for 1854:--"a cow, belonging to mr. john marshall, of repton, on wednesday last, gave birth to _five, live healthy calves_, all of which are, at the time i write, alive and vigorous, and have every appearance of continuing so. they are all nearly of a size, and are larger and stronger than could be supposed. four of them are bull-calves. "the dam is by no means a large one, is eleven years old, of a mongrel breed, and has never produced more than one offspring at any previous gestation. i saw her two days after she had calved, at which time she was ruminating, and did not manifest any unusual symptoms of exhaustion. i may mention that the first four calves presented naturally; the fifth was a breech-presentation." cleansing.--the _placenta_, or after-birth, by which the _foetus_ is nourished while in embryo, should be removed soon after calving. generally, it will come away without any assistance. this is what is called "cleansing after calving." when, however, it remains for some time, its function having been performed, it becomes a foreign body, exciting uterine contractions, and therefore injurious. the sooner, then, it is removed, the better for the animal as well as the owner. to accomplish this, the hand should be introduced, and, by pulling gently in various directions, it will soon yield and come away. should it be allowed to remain, it rapidly decomposes, producing a low, feverish condition of the system, which greatly interferes with the general health of the animal. inversion of the uterus.--the _uterus_ is sometimes turned inside out after calving. this is, generally, the result of debility, or severe labor. the _uterus_ should be replaced as carefully as possible with the hands, care being taken that no dirt, straw, or other foreign substance adheres to it. should it again be expelled, it would be advisable to quiet the system by the use of an anæsthetic, as chloroform, or--which is much safer--chloric ether. as soon as the animal is under the influence of this, the _uterus_ may be again replaced. the hind-quarters should be raised as high as possible, in order to favor its retention. the animal should have a little gruel and a bottle of porter given to her every five or six hours, and the _vulva_ should be bathed frequently with cold water. phrenitis. inflammation of the brain is one of those dreadful diseases to which all animals are liable. it is known to the farmer as frenzy, mad staggers, etc. the active symptoms are preceded by stupor; the animal stubbornly stands in one position; the eyes are full, red, and fiery; respiration rapid; delirium soon succeeds; the animal, bellowing, dashes wildly about, and seems bent on mischief, rushing madly at every object which comes in its way. the causes of this disease are overwork in warm weather, a plethoric condition of the system, and too stimulating food. prof. gamgee, of the edinburgh veterinary college, relates a case resulting from the presence within the external _meatus_ of a mass of concrete cerumen, or wax, which induced inflammation of the ear, extending to the brain. _treatment._--as this is attended with considerable risk, unless it is taken prior to the frenzied stage, bleeding almost to fainting should be resorted to, and followed by a brisk purge. take one ounce of barbadoes aloes, and ten to fifteen drops of croton-oil; mix the aloes with one pint of water and the oil, using the mixture as a drench. one pound of epsom-salts will answer the purpose very well, in cases where the aloes and oil cannot be readily obtained. application of bags of broken ice to the head, is very beneficial. spirits of turpentine, or mustard, together with spirits of hartshorn and water should be well rubbed in along the spine, from the neck to the tail. pleurisy. this is an inflammation of the _pleura_, or the serous membrane which lines the cavity of the chest, and which is deflected over the lungs. inflammation of this membrane rarely occurs in a pure form, but is more generally associated with inflammation of the tissue of the lungs. if this disease is not attended to at an early period, its usual termination is in hydrothorax, or dropsy of the chest. the same causes which produce inflammation of the lungs, of the bronchia, and of the other respiratory organs, produce also pleurisy. _symptoms._--the respiration is quick, short, and painful; pressure between the ribs produces much pain; a low, short, painful cough is present; the respiratory murmur is much diminished,--in fact, it is scarcely audible. this condition is rapidly followed by effusion, which may be detected from the dullness of the sounds, on applying the ear to the lower part of the lungs. the febrile symptoms disappear; the animal for a few days appears to improve, but soon becomes weak, languid, and often exhausted from the slightest exertion. _treatment._--the same treatment in the early stage is enjoined as in inflammatory pneumonia, which the reader will consult--counter-irritation and purgatives. bleeding never should be resorted to. when effusion takes place, it is necessary to puncture the sides with a trochar, and draw away the fluid, giving internally one of the following purges three times a day: rosin, eight ounces; saltpetre, two ounces, mix, and divide into eight powders. half-drachm doses of the iodide of potash, dissolved in water, to be given three times daily, will be found useful in this disease. pleuro-pneumonia. this disease, as its name implies, is an inflammatory condition of the lungs and the _pleura_, or the enveloping membrane of the lungs and the lining membrane of the chest. it is sometimes called contagious, infectious, and epizoötic pleuro-pneumonia,--contagious or infectious, from its supposed property of transmission from the diseased to the healthy animal. [illustration: taking an observation.] a contagious character the author is not ready to assign to it,--contagious, as he understands it, being strictly applicable to those diseases which depend upon actual contact with the poison that it may be communicated from one animal to another. this does not necessarily imply the actual touching of the animals themselves; for it may be communicated from the poison left in the trough, or other places where the diseased animal has been brought in contact with some object, as is often the case in glanders in the horse; the matter discharged from the nose, and left upon the manger, readily communicating that disease to healthy animals coming in contact with it. contagious diseases, therefore, travel very slowly, starting, as they do, at one point, and gradually spreading over a large district, or section of country. this disease is, however, regarded by the author as infectious; by which term is meant that it is capable of being communicated from the diseased to the healthy animal through the medium of the air, which has become contaminated by the exhalations of poisonous matter. the ability to inoculate other animals in this way is necessarily confined to a limited space, sometimes not extending more than a few yards. infectious diseases, accordingly, spread with more rapidity than contagious ones, and are, consequently, more to be dreaded; since we can avoid the one with comparatively little trouble, while the other often steals upon us when we regard ourselves as beyond its influence, carrying death and destruction in its course. the term by which this disease is known, is a misnomer. pleuro-pneumonia proper is neither a contagious, nor an infectious disease; hence, the denial of medical men that this so-called pleuro-pneumonia is a contagious, or infectious disease, has been the means of unnecessarily exposing many animals to its poisonous influence. in the _recuéil de médécine vétérinaire_, for 1833, will be found a very interesting description of this fatal malady. the author, m. lecoy, assistant professor at the veterinary school of lyons, france, says: "there are few districts in the _arrondissement_ of avesnes where more cattle are fattened than in that of soire-le-chateau. the farmers being unable to obtain a sufficient supply of cattle in the district, are obliged to purchase the greater part of them from other provinces; and they procure a great number for grazing from franche comté. the cattle of this country are very handsome; their forms are compact; they fatten rapidly; and they are a kind of cattle from which the grazer would derive most advantage, were it not that certain diseases absorb, by the loss of some of the animals, the profits of the rest of the herd. amongst the diseases which most frequently attack the cattle which are brought from the north, there is one very prevalent in some years, and which is the more to be dreaded as it is generally incurable; and the slaughter of the animal, before he is perceptibly wasted, is the only means by which the farmer can avoid losing the whole value of the beast. "this disease is chronic pleuro-pneumonia. the symptoms are scarcely recognizable at first, and often the beast is ill for a long time without its being perceived. he fattens well, and when he is slaughtered the owner is astonished to find scarcely half of the lungs capable of discharging the function of respiration. when, however, the ox has not sufficient strength of constitution to resist the ravages of disease, the first symptom which is observed is diminution, or irregularity of appetite. soon afterwards, a frequent, dry cough is heard, which becomes feeble and painful as the disease proceeds. the dorso-lumbar portion of the spine (loins) grows tender; the animal flinches when the part is pressed upon, and utters a peculiar groan, or grunt, which the graziers regard as decisive of the malady. "quickly after this, the movements of the flanks become irregular and accelerated, and the act of respiration is accompanied by a kind of balancing motion of the whole body. the sides of the chest become as tender as the loins, or more so; for the animal immediately throws himself down, if pressed upon with any force. the elbows become, in many subjects, more and more separated from the sides of the chest. the pulse is smaller than natural, and not considerably increased. the muzzle is hot and dry, alternately. the animal lies down as in a healthy state, but rumination is partially or entirely suspended. the _fæces_ are harder than they should be; the urine is of its natural color and quantity; the mouth is often dry; and the horns and ears retain their natural temperature. "this first stage of the disease sometimes continues during a month, or more, and then, if the animal is to recover, or at least, apparently so, the symptoms gradually disappear. first of all, the appetite returns, and the beast begins to acquire a little flesh. the proprietor should then make haste and get rid of him; for it is very rare that the malady, however it may be palliated for a while, does not reappear with greater intensity than before. "in most cases, the disease continues to pursue its course toward its termination without any remission,--every symptom gradually increasing in intensity. the respiration becomes more painful; the head is more extended; the eyes are brilliant; every expiration is accompanied with a grunt, and by a kind of puckering of the angles of the lips; the cough becomes smaller, more suppressed, and more painful; the tongue protrudes from the mouth, and a frothy mucus is abundantly discharged; the breath becomes offensive; a purulent fluid of a bloody color escapes from the nostrils; diarrhoea, profuse and fetid, succeeds to the constipation; the animal becomes rapidly weaker; he is a complete skeleton, and at length he dies. "examination after death discloses slight traces of inflammation in the intestines, discoloration of the liver, and a hard, dry substance contained in the manyplus. the lungs adhere to the sides and to the diaphragm by numerous bands, evidently old and very firm. the substance of the lungs often presents a reddish-gray hepatization throughout almost its whole extent. at other times, there are tubercles in almost every state of hardness, and in that of suppuration. the portion of the lungs that is not hepatized is red, and gorged with blood. besides the old adhesions, there are numerous ones of recent date. the pleura is not much reddened, but by its thickness in some points, its adhesion in others, and the effusion of a serous fluid, it proves how much and how long it has participated in the inflammatory action. the trachea and the bronchia are slightly red, and the right side of the head is gorged with blood. "in a subject in which, during life, i could scarcely feel the beating of the heart, i found the whole of the left lobe of the lungs adhering to the sides, and completely hepatized. in another, that had presented no sign of disease of the chest, and that for some days before his death vomited the little fodder which he could take, the whole of that portion of the oesophagus that passed through the chest was surrounded with dense false membranes, of a yellowish hue, ranging from light to dark, and being in some parts more than an inch in thickness, and adhering closely to the muscular membrane of the tube, without allowing any trace to be perceived of that portion of the mediastinal pleura on which this unnatural covering was fixed and developed. "the cattle purchased in franche comté are brought to avesnes at two periods of the year--in autumn and in the spring. those which are brought in autumn are much more subject to the disease than those which have arrived in the spring; and it almost always happens that the years in which it shows itself most generally are those in which the weather was most unfavorable while the cattle were on the road. the journey is performed by two different routes,--through lorraine and through champagne,--and the disease frequently appears in cattle that have arrived by one of these routes. the manner in which the beasts are treated, on their arrival, may contribute not a little to the development of the malady. these animals, which have been driven long distances in bad weather, and frequently half starved, arrived famished, and therefore the more fatigued, and some of them lame. calculating on their ravenous appetite, the graziers, instead of giving them wholesome food, make them consume the worst that the farm contains,--musty and mouldy fodder; and it is usually by the cough, which the eating of such food necessarily produces, that the disease is discovered and first developed. "is chronic pleuro-pneumonia contagious? the farmers believe that it is, and i am partly of their opinion. when an animal falls sick in the pasture, the others, after his removal, go and smell at the grass where he has lain, and which he has covered with his saliva, and, after that, new cases succeed to the first. it is true that this fact is not conclusive, since the disease also appears in a great number of animals that have been widely separated from each other. but i have myself seen three cases in which the cattle of the country, perfectly well before, have fallen ill, and died with the same symptoms, excepting that they have been more acute, after they have been kept with cattle affected with this disease. this circumstance inclines me to think that the disease is contagious; or, at least, that, in the progress of it, the breath infects the cow-house in which there are other animals already predisposed to the same disease. i am induced to believe that most of the serious internal diseases are communicated in this manner, and particularly those which affect the organs of respiration, when the animals are shut up in close, low, and badly-ventilated cow-houses." [_rec. de méd. vét. mai, 1833._] no malady can be more terrible and ruinous than this among dairy-stock; and its spread all over the country, together with its continuance with scarcely any abatement, must be attributed to the combination of various causes. the chief are: _first_, the very contagious or infectious nature of the disorder; _second_, inattention on the part of government to the importation and subsequent sale of diseased animals; and, _third_, the recklessness of purchasers of dairy or feeding cattle. this disease may be defined as an acute inflammation of the organs of the chest, with the development of a peculiar and characteristic poison, which is the active element of infection or contagion. it is a disease peculiar to the cattle tribe, notwithstanding occasional assertions regarding observations of the disease among horses, sheep, and other animals,--which pretended observations have not been well attested. the infectious, or contagious nature of this virulent malady is incontestibly substantiated by an overwhelming amount of evidence, which cannot be adduced at full length here, but which may be classified under the following heads: _first_, the constant spreading of the disease from countries in which it rages to others which, previously to the importation of diseased animals, had been perfectly free from it. this may be proved in the case of england, into which country it was carried in 1842, by affected animals from holland. twelve months after, it spread from england to scotland, by means of some cattle sold at all-hallow fair, and it was only twelve months afterward that cattle imported as far north as inverness took the disease there. lately, a cow taken from england to australia was observed to be diseased upon landing, and the evil results were limited to her owner's stock, who gave the alarm, and ensured an effectual remedy against a wider spread. besides, the recent importation of pleuro-pneumonia into the united states from holland appears to have awakened our agricultural press generally, and to have convinced them of the stubborn fact that our cattle have been decimated by a fearfully infectious, through probably preventable, plague. a letter from this country to an english author says: "its (pleuro-pneumonia's) contagious character seems to be settled beyond a doubt, though some of the v.s. practitioners deny it, which is almost as reasonable as it would be to deny any other well-authenticated historic fact. every case of the disease is traceable to one of two sources; either to mr. chenery's stock in belmont (near boston, massachusetts), into which the disease was introduced by his importation of four dutch cows from holland, which arrived here the 23d of last may; or else to one of the three calves which he sold to a farmer in north brookfield, massachusetts, last june." _2dly._ apart from the importation into countries, we have this certain proof--to which special attention was drawn several years ago--that cattle-dealers' farms, and public markets, constitute the busy centres of infection. most anxious and careful inquiries have established the proposition that in breeding-districts, where the proprietors of extensive dairies--as in dumfries, scotland, and other places--abstain from buying, except from their neighbors, who have never had diseases of the lungs amongst their stock, pleuro-pneumonia has not been seen. there is a wide district in the vicinity of abington, england, and in the parish of crawford, which has not been visited _by_ this plague, with the exception of two farms, into which market-cattle had been imported and thus brought the disease. _3dly._ in 1854 appeared a report of the researches on pleuro-pneumonia, by a scientific commission, instituted by the minister of agriculture in france. this very able pamphlet was edited by prof. bouley, of alfort, france. the members of the commission belonged to the most eminent veterinarians and agriculturists in france. magendie was president; regnal, secretary; besides rayer, the renowned comparative pathologist; yvart, the inspector-general of the imperial veterinary schools; renault, inspector of the imperial veterinary schools; delafond, director of alfort college; bouley, lassaigne, baudemont, doyére, manny de morny, and a few others representing the public. if such a commission were occasionally appointed in this country for similar purposes, how much light would be thrown on subjects of paramount importance to the agricultural community! conclusions arrived at by the commission are too important to be overlooked in this connection. the reader must peruse the report itself, if he needs to satisfy himself as to the care taken in conducting the investigations: but the foregoing names sufficiently attest the indisputable nature of the facts alluded to. in instituting its experiments, the commission had in view the solving of the following questions:-_1stly._ is the epizoötic pleuro-pneumonia of cattle susceptible of being transmitted from diseased to healthy animals by cohabitation? _2dly._ in the event of such contagion's existing, would all the animals become affected, or what proportion would resist the disease? _3dly._ amongst the animals attacked by the disease, how many recover, and under what circumstances? how many succumb? _4thly._ are there any animals of the ox species decidedly free from any susceptibility of being affected from the contagion of pleuro-pneumonia? _5thly._ do the animals, which have been once affected by a mild form of the disease, enjoy immunity from subsequent attacks? _6thly._ do the animals, which have once been affected by the disease in its active form, enjoy such immunity? to determine these questions, the commission submitted at different times to the influence of cohabitation with diseased animals forty-six perfectly healthy ones, chosen from districts in which they had never been exposed to a similar influence. of these forty-six animals, twenty were experimented on at pomeraye, two at charentonneau, thirteen at alfort, and eleven, in the fourth experiment, at charentonneau. of this number, twenty-one animals resisted the disease when first submitted to the influence of cohabitation, ten suffered slightly, and fifteen took the disease. of the fifteen affected, four died, and eleven recovered. consequently, the animals which apparently escaped the disease at the first trial amounted to 45.65 per cent., and those affected to 21.73 per cent. of these, 23.91 per cent. recovered, and 8.69 per cent. died. but the external appearances in some instances proved deceptive, and six of the eleven animals of the last experiment, which were regarded as having escaped free, were found, on being destroyed, to bear distinct evidence of having been affected. this, therefore, modifies the foregoing calculations, and the numbers should stand thus:-15 enjoy immunity, or 32.61 per cent. 10 indisposed, " 21.73 " 17 animals cured, " 36.95 " 4 dead, " 8.98 " of the forty-two animals which were exposed in the first experiments at pomeraye and charentonneau, and which escaped either without becoming affected, or recovering, eighteen were submitted to a second trial; and of these eighteen animals, five had, in the first experiment, suffered from the disease and had recovered; five had now become affected; and four had been indisposed. the four animals submitted to the influence of contagion a third time, had been affected on the occasion of the first trial. none of the eighteen animals contracted the disease during these renewed exposures to the influence of contagion. from the results of these experiments, the commission drew the following conclusions:-_1stly._ the epizoötic pleuro-pneumonia is susceptible of being transmitted from diseased to healthy animals by cohabitation. _2dly._ all the animals exposed do not take the disease; some suffer slightly, and others not at all. _3dly._ of the affected animals, some recover and others die. _4thly._ the animals, whether slightly or severely affected, possess an immunity against subsequent attacks. these are the general conclusions which the commission deemed themselves authorized to draw from their experiments. the absolute proportion of animals which become affected, or which escape the disease, or of those which die and which recover, as a general rule, cannot be deduced from the foregoing experiments, which, for such a purpose, are too limited. the commission simply state the numbers resulting from their experiments. from these it transpires that forty five of the animals became severely affected with pleuro-pneumonia, and twenty-one per cent. took the disease slightly, making the whole sixty-six per cent. which were more or less severely attacked. thirty-four per cent. remained free from any malady. the proportion of animals which re-acquired their wonted appearance of health amounted to eighty-three per cent., whereas seventeen per cent. died. many minor points might be insisted on, but it is sufficient here to say, that the most careful analysis of all facts has proved to practical veterinarians, as well as to experienced agriculturists, and must prove to all who will calmly and dispassionately consider the point, that pleuro-pneumonia is pre-eminently an infectious, or contagious disease. [illustration: the twins.] _symptoms._--from the time that an animal is exposed to the contagion to the first manifestation of symptoms, a certain period elapses. this is the period of incubation. it varies from a fortnight to forty days, or even several months. the first signs, proving that the animal has been seized, can scarcely be detected by any but a professional man; though, if a proprietor of cattle were extremely careful, and had pains-taking individuals about his stock, he would invariably notice a slight shiver as ushering in the disorder, which for several days, even after the shivering fit, would limit itself to slight interference in breathing, readily detected on auscultation. perhaps a cough might be noticed, and that the appetite and milk-secretion diminished. the animal becomes costive, and the shivering fits recur. the cough becomes more constant and oppressive; the pulse full and frequent, usually numbering about eighty per minute at first, and rising to upwards of one hundred. the temperature of the body rises, and all the symptoms of acute fever set in. a moan, or grunt, in the early part of the disease indicates a dangerous attack, and the _alae nasi_ (cartilages of the nose) rise spasmodically at each inspiration; the air rushes through the inflamed windpipe and bronchial tubes, so as to produce a loud, coarse respiratory murmur; and the spasmodic action of the abdominal muscles indicates the difficulty the animal also experiences in the act of expiration. pressure over the intercostal (between the ribs) spaces, and pressing on the spine, induce the pain so characteristic of pleurisy, and a deep moan not infrequently follows such an experiment. the eyes are bloodshot, mouth clammy, skin dry and tightly bound to the subcutaneous textures, and the urine is scanty and high-colored. upon auscultation, the characteristic dry, sonorous _râle_ of ordinary bronchitis may be detected along the windpipe, and in the bronchial tubes. a loud sound of this description is, not infrequently, detected at the anterior part of either side of the chest; whilst the respiratory murmur is entirely lost, posteriorly, from consolidation of the lungs. a decided leathery, frictional sound is detected over a considerable portion of the thoracic surface. as the disease advances, and gangrene, with the production of cavities in the lungs, ensues, loud, cavernous _râles_ are heard, which are more or less circumscribed, occasionally attended by a decided metallic noise. when one lobe of the lungs is alone affected, the morbid sounds are confined to one side, and on the healthy side the respiratory murmur is uniformly louder all over. by carefully auscultating diseased cows from day to day, interesting changes can be discovered during the animal's lifetime. frequently, the abnormal sounds indicate progressive destruction; but, at other times, portions of the lungs that have been totally impervious to air, become the seat of sibilant _râles_, and gradually, a healthy respiratory murmur proves that, by absorption of the materials which have been plugging the tissues of the lungs, resolution is fast advancing. some very remarkable cases of this description have been encountered in practice. unfortunately, we often find a rapid destruction of the tissues of the lungs, and speedy dissolution. in other instances, the general symptoms of hectic, or consumption, attend lingering cases, in which the temperature of the body becomes low, and the animal has a dainty appetite, or refuses all nourishment. it has a discharge from the eyes, and a fetid, sanious discharge from the nose. not infrequently, it coughs up disorganized lung-tissue and putrid pus. great prostration, and, indeed, typhus symptoms, set in. there is a fetid diarrhoea, and the animal sinks in the most emaciated state, often dying from suffocation, in consequence of the complete destruction of the respiratory structures. _post mortem_ appearances.--in acute cases, the cadaverous lesions chiefly consist in abundant false membranes in the trachea, or windpipe, and closure of the bronchial tubes by plastic lymph. the air-vesicles are completely plugged by this material, and very interesting specimens may be obtained by careful dissection, in the shape of casts of the bronchial tubes and air-vesicles, clustered together like bunches of grapes. on slicing the lungs in these cases, hepatization is observed, presenting a very peculiar appearance, which is, in a great measure, due to the arrangement of the lung-tissue in cattle. the pulmonary lobules are of a deep-red or brown color, perfectly consolidated, and intersected or separated, one from the other, by lighter streaks of yellowish-red lymph, occupying the interlobular, areolar tissue. in the more chronic cases, the diseased lobes and lobules are found partly separated from the more healthy structures. this occurs from gangrene, and putrefactive changes, or in some instances, from the ulcerative process, so constantly observed in the segregation of dead from living tissues. abscesses are not infrequently found in different parts of the lungs. sometimes circumscribed, at others connected with bronchial tubes, and not infrequently communicating with the pleural cavity. true empyema is not often seen; but, at all times, the adhesions between the costal and visceral pleura are extensive, and there is much effusion in the chest. in dressed carcasses of cows that have been slaughtered from pleuro-pneumonia, even though the disease has not been far advanced, it will be found that the butcher has carefully scraped the serous membrane off the inner surface of the ribs, as it would otherwise be impossible for him to give the pleura its healthy, smooth aspect, from the firm manner in which the abundant false membranes adhere to it. the diseased lungs sometimes attain inordinate weight. they have been known to weigh as much as sixty pounds. _treatment._--the veterinary profession is regarded by many who have sustained heavy losses from pleuro-pneumonia, as deeply ignorant, because its members cannot often cure the disease. persons forget that there are several epidemics which prove equally difficult to manage on the part of the physician, such as cholera, yellow fever, etc. the poison in these contagious, epizoötic diseases is so virulent that the animals may be regarded as dead from the moment they are attacked. its elimination from the system is impossible, and medicine cannot support an animal through its tardy, exhausting, and destructive process of clearing the system of so potent a virus. all antiphlogistic means have failed, such as blood-letting and the free use of evacuants. derivatives, in the form of mustard-poultices, or more active blisters, are attended with good results. stimulants have proved of the greatest service; and the late prof. tessona, of turin, strongly recommended, from the very onset of the disease, the administration of strong doses of quinine. maffei, of ferrara, states that he has obtained great benefit from the employment of ferruginous tonics and manganese in the very acute stage of the malady, supported by alcoholic stimulants. recently, the advantages resulting from the use of sulphate of iron, both as a preventive and curative, have been exhibited in france. it would appear that the most valuable depurative method of treatment yet resorted to is by the careful use of the roman bath. acting, like all other sudorifics in cases of fever and blood diseases, it carries off by the skin much of the poison, without unduly lowering the vital powers. _prevention._--the rules laid down in denmark, and indeed in many other places, appear the most natural for the prevention of the disease. if they could be carried out, the disease must necessarily be stopped; but there are practical and insuperable difficulties in the way of enforcing them. thus, a dr. warneke says, prevention consists in "the avoidance of contagion; the slaughter of infected beasts; the prohibition of keeping cattle by those whose cattle have been slaughtered, for a space of ten weeks after the last case occurring; the disinfection of stalls vacated by slaughtering; the closing of infected places to all passing of cattle; especial attention to the removal of the dung, and of the remains of the carcasses of slaughtered beasts; and, finally, undeviating severity of the law against violators." dr. williams, of hasselt, suggested and carried out, in 1851, the inoculation of the virus of pleuro-pneumonia, in order to induce a mild form of the disease in healthy animals, and prevent their decimation by the severe attacks due to contagion. he met with much encouragement, and perhaps more opposition. didot, corvini, ercolani, and many more accepted dr. williams's facts as incontestable, and wrote, advocating his method of checking the spread of so destructive a plague. the first able memoir which contested all that has been said in favor of inoculation, appeared in turin, and was written by dr. riviglio, a piedmontese veterinary surgeon. this was supported by the views of many others. prof. simonds wrote against the plan, and, in 1854, the french commission, whose report has been before mentioned, confirmed, in part, riviglio's views, though, from the incompleteness of the experiments, further trials were recommended. inoculation is performed as follows: a portion of diseased lung is chosen, and a bistoury or needle made to pierce it so as to become charged with the material consolidating the lung, and this is afterward plunged into any part, but, more particularly, toward the point of the tail. if operated severely, and higher up, great exudation occurs, which spreads upward, invades the areolar tissue round the rectum and other pelvic organs, and death soon puts an end to the animal's excruciating suffering. if the operation is properly performed with lymph that is not putrid, and the incisions are not made too deep, the results are limited to local exudation and swelling, general symptoms of fever, and gradual recovery. the most common occurrence is sloughing of the tail; and in london, at the present time, dairies are to be seen in which all the cows have short-tail stumps. dr. williams and others have gone too far in attempting to describe a particular corpuscle as existing in the lymph of pleuro-pneumonia. all animal poisons can be alone discovered from their effects. in structure and chemical constitution, there is no difference, and often the most potent poisons are simple fluids. the belgian commission, appointed to investigate the nature and influence of inoculation for pleuro-pneumonia, very justly expressed an opinion that dr. williams had not proved that a specific product, distinguished by anatomical characters, and appreciable by the microscope, existed in this disease. the all-important question, "is inoculation of service?" has to the satisfaction of most been solved. the belgian and french commissions, the observations of riviglio, simond, herring, and many others, prove that a certain degree of preservative influence is derived by the process of inoculation. it does not, however, arrest the progress of the disease. it certainly diminishes to some extent--though often very slightly so--the number of cases, and, particularly, of severe ones. this effect has been ascribed to a derivative action, independent of any specific influence, and, indeed, similar to that of introducing setons in the dewlap. in london, some dairymen have considerable faith in inoculation, though its effect is uncertain, and the manner of its working a mystery. the best counsel, in the premises, which can be given to the keeper of dairy stock is, to select his own animals from healthy herds, and strictly to avoid public markets. in many instances, a faithful observance of these injunctions has been sufficient to prevent the invasion of this terrible disease. [gamgee.] the existence of this disease in the united states was not generally known until the year 1859, when mr. chenery, of belmont, near boston, massachusetts, imported several cows from holland, which arrived in the early part of the spring of that year. some of the animals were sick when they arrived, but the true nature of the disease was not at that time suspected. several of them were so bad that they were carried in trucks to mr. chenery's barn. some two months passed away before the character of the disease was discovered. upon the facts becoming known, the citizens of massachusetts became panic-stricken, as the disease was rapidly spreading over that state. an extra session of the legislature was speedily convened, when a joint special committee was appointed, to adopt and carry out such measures as in their judgment seemed necessary for the extirpation of this monster, pleuro-pneumonia. the committee met in the hall of the house of representatives, thursday, may, 31, 1860, to receive evidence as to the contagious or infectious character of the disease, in order to determine concerning the necessity of legislative action. mr. walker, one of the commissioners appointed by the governor, made the following statement: "the disease was introduced into north brookfield from belmont. mr. curtis stoddard, a young man of north brookfield, went down, the very last of june, last year, and purchased three calves of mr. chenery, of belmont. he brought these calves up in the cars to brookfield. on their way from the depôt to his house, about five miles, one of the calves was observed to falter, and when he got to his house, it seemed to be sick, and in two or three days exhibited very great illness; so much so, that his father came along, and, thinking he could take better care of it, took the calf home. he took it to his own barn, in which there were about forty head of cattle; but it grew no better, and his son went up and brought it back again to his own house. in about ten days after that, it died. his father, who had had the calf nearly four days, in about a fortnight afterward observed that one of his oxen was sick, and it grew worse very fast and died. two weeks after, a second also sickened, and died. then a third was attacked and died, the interval growing wider from the attack of one animal to that of another, until he had lost eight oxen and cows. young stoddard lost no animal by the infection,--that is, no one died on his hands. prior to the appointment of this commission, about the first of november,--for reasons independent of this disease, which i don't suppose he then knew the nature of,--he sold off his stock. he sold off eleven heifers, or young animals, and retained nine of the most valuable himself; which shows that he did not then know any thing was the matter with them. "these nine were four oxen, and five young cattle. the four he took to his father's, three of the others to his uncle's, and the remaining two to his father-in-law's; distributing them all among his friends,--which furnishes another proof that he did not suppose he was doing any mischief. he disposed of his herd in that way. from this auction, these eleven animals went in different directions, and wherever they went, they scattered the infection. without a single failure the disease has followed those cattle; in one case, more than two hundred cattle having been infected by one which was sold at curtis stoddard's auction, when he was entirely ignorant of the disease. "when the commission was appointed, they went and examined his cattle, and were satisfied that they were diseased,--at least, some of them. they examined his father's herd, and found that they were very much diseased; and when we came to kill curtis stoddard's cattle, seven of the nine head were diseased. two were not condemned, because the law says, 'cattle not appearing to be diseased, shall be appraised.' nevertheless, it proved that these animals were diseased; so that his whole herd was affected. "in regard to leonard stoddard's cattle, he lost fourteen of his animals before the commissioners went to his place. they took eighteen more, all of which were diseased,--most of them very bad cases,--indeed, extreme cases. that left eight heads, which were not condemned, because not appearing to be diseased. here i remark, that when this disease is under the shoulder-blade, it cannot be detected by percussion. the physicians did not say that the animal was not diseased, but that they did not see sufficient evidence upon which to condemn. such animals were to be paid for, upon the ground of their not appearing to be diseased. nevertheless, it is proper to state that the remaining eight which were not condemned, were suspected to be diseased, and we told mr. stoddard that we had the impression that they were diseased, notwithstanding appearances. he said, 'there is a three-year-old animal that has never faltered at all. she has never manifested the slightest disease. if you will kill her, and she is diseased, i shall make up my mind that i have not a well animal in my stalls.' we killed the animal, and found her to be badly diseased. "thus, the first two herds were all infected by the disease; and in the last of curtis stoddard's oxen which we killed, we found a cyst in the lungs of each. one of these lungs is now in this building, never having been cut open, and medical men can see the cyst which it contains. i have said in what manner mr. curtis stoddard's cattle spread the infection. "in regard to mr. leonard stoddard's: in the first place, he kept six or eight oxen which he employed in teaming. he was drawing some lumber, and stopped over night, with his oxen, at mr. needham's. needham lost his whole herd. he lost eight or ten of them, and the rest were in a terrible condition. seven or eight more were condemned, and his whole herd was destroyed, in consequence of mr. stoddard's stopping with him over night. mr. stoddard sold an animal to mr. woodis of new braintree. he had twenty-three fine cows. it ruined his herd utterly. seven or eight animals died before the commissioners got there. mr. l. stoddard also sold a yoke of cattle to mr. olmstead, one of his neighbors, who had a very good herd. they stayed only five days in his hands, when they passed over to mr. doane. in these five days they had so infected his herd that it was one of the most severe instances of disease that we have had. one third were condemned, and another third were passed over as sound, whether they were so, or not. they did not appear to be diseased. the cattle that were passed from mr. stoddard through mr. olmstead to mr. doane, were loaned by mr. d. to go to a moving of a building from oakham to new braintree. they were put in with twenty-two yoke of cattle, and employed a day and a half. it has since been proved that the whole of these cattle took the contagion. they belonged to eleven different herds, and of course, each of these herds formed a focus from which the disease spread. now, in these two ways the disease has spread in different directions. "but, when the commissioners first commenced, they had no idea that the disease extended further than those herds in which there were animals sick. hence, their ideas and the ideas of those who petitioned for the law, did not extend at all to so large a number of herds as have since been proved to be diseased, because they only judged of those who manifested disease. as soon as we began in that circle, we found a second circle of infection, and another outside of that; and by that time it had branched off in various directions to various towns. it assumed such proportions that it was very evident that the commissioners had not the funds to perform the operations required by the law. the law confines the commissioners to one operation,--killing and burying. no discretionary power is given at all. the commissioners became entirely dissatisfied with that condition of things, because other measures besides merely killing and burying, are quite as necessary and important. when they arrived at that point and discovered to what extent the infection had spread, they stopped killing the herds, and i believe there has not been a herd killed for twenty days. "the policy was then changed to circumscribing the disease, by isolating the herds just as fast as possible and as surely as possible. a man's herd has been exposed. there is no other way than to go and examine it, and take the diseased animals away. then he knows the animals are diseased, and his neighbors know it. that has been the business of the commissioners for the last twenty days; and the facts that they have no discretionary power whatever, and that they were entirely circumscribed in their means, and that it was hard for the farmers to lose their stock and not be paid for it,--induced them to petition the governor, in connection with the board of agriculture, for the calling of a session of the legislature, to take measures for the extinction of the disease." in response to a question, "whether any animals that had once been affected, had afterward recovered?"--the same gentleman stated that instances had occurred where cattle had been sick twice, and had, apparently, fully recovered; they ruminated readily, and were gaining flesh. upon examination, however, they were pronounced diseased, and, when killed, both lungs were found in a hopeless case, very badly diseased. dr. george b. loring, another of the commissioners, stated that eight hundred and forty-two head of cattle had, at that time, been killed, and that, from a careful estimate, there still remained one thousand head, which should either be killed, or isolated for such a length of time as should establish the fact that they had no disease about them. twenty thousand dollars and upwards had already been appraised as the value of the cattle then killed. as to disinfecting measures, the farmers who had lost cattle were requested to whitewash their barns thoroughly, and some tons of a disinfecting powder were purchased for the advantage of the persons who wished to use it. an early application was advised, that the barns might be in readiness for hay the then coming season. the practice adopted by the commissioners was, to appraise the cattle whenever a herd was found which had been exposed, and a surgeon was appointed to pass judgment upon the number of diseased animals. after that judgment, the remaining animals that were pronounced sound were killed and passed to the credit of the owner, after an appraisement made by these persons. the fair market-prices were paid, averaging about thirty-three dollars a head. at the time of the meeting of the committee, some seventy cattle had died of the disease. an examination was made of some of the animals killed, and the following facts obtained:-case 1.--this cow had been sick for nineteen days; was feeble, without much appetite, with diarrhoea, cough, shortness of breathing, hair staring, etc. percussion dull over the whole of the left side of the chest; respiration weak. killed by authority. several gallons of serum were found in the left side of the chest; a thick, furzy deposit of lymph over all the _pleura-costalis_. this lymph was an inch in thickness, resembling the velvety part of tripe, and quite firm. there was a firm deposit of lymph in the whole left lung, but more especially at its base, with strong adhesions to the diaphragm and _pleura-costalis_ near the spine. the lung was hard and brittle, like liver, near its base. no pus. right lung and right side of chest healthy. case 2.--this cow was taken very sick, january 30th. in fourteen days, she began to get better. april 12th, she is gaining flesh, breathes well, hair healthy, gives ten quarts of milk a day, and in all other respects bids fair for a healthy animal hereafter, except a slight cough. percussion dull over base of the left lung, near the spine, and respiration feeble in the same regions. autopsy.--left lung strongly adherent to diaphragm and costal pleura; the long adhesions well smoothed off; _pleura-costalis_ shining and healthy. also, the surface of the lung, when there were no adhesions, sound and right; all the lung white, and free for the entrance of air, except the base, in which was a cyst containing a pint or two of pus. loose in this pus was a hard mass, as large as a two-quart measure, looking like marble; when cut through its centre, it appeared like the brittle, hardened lining in case 1. it appeared as though a piece of lung had been detached by suppuration and enclosed in an air-tight cyst, by which decomposition was prevented. the other lung and the chest were sound. it is to be inferred, as there were adhesions, that there had been pleurisy and deposit of lymph and serum, as in case 1, and that nature had commenced the cure by absorbing the serum from the chest, and the lymph from the free pleural surface, and smoothed off every thing to a good working condition. the lump in the cyst was brittle and irregular on its surface, as though it was dissolving in the pus. no good reason can be given why nature should not consummate the work which she had so wisely begun. case 3.--this cow had been sick fourteen days; was coughing and breathing badly; percussion dull over both chests and respiration feeble. killed. autopsy.--both chests filled with water; deposits of lymph over all the _pleura-costalis_, presenting the same velvety, furzy appearance as in case 1. both lungs were hardened at the base, and the left throughout its whole extent, and firmly adherent to diaphragm and costal pleura, near the spine. the right lung had nearly one-third of its substance in a condition for the entrance of air; but this portion, even, was so compressed with the water, that a few hours longer would have terminated the case fatally without state aid. this case had not proceeded far enough for the formation of the cyst or pus. in mr. needham's herd, about twenty-eight days intervened between the first and second case of disease, instead of about fourteen, as in mr. olmstead's. case 4.--a nice heifer, in fair condition, eating well, only having a slight cough. percussion dull over base of the left lung. autopsy.--base of left lung adherent to diaphragm and costal pleura; lung hardened. on cutting into base, found ulceration and a head of timothy grass, four or five inches long. animal in every other way well. case 5.--this cow was taken, january 1st, with a cough, difficulty of breathing, and the other symptoms of the disease, and continued sick till march 1st. on taking her out, april 12th, to be slaughtered, she capered, stuck up her tail, snuffed, and snorted, showing all the signs of feeling well and vigorous. autopsy.--right lung firmly adherent to diaphragm and costal pleura, near the spine. base of lung hardened, containing a cyst with a large lump, of the size of a two-quart measure, floating in pus; outside of the lump was of a dirty yellow-white, irregular, brittle, and cheesy; the inside mottled, or divided into irregular squares; red like muscle, and breaking under the finger, like liver. costal pleura smooth, shining; adhesions where there was motion; card-like and polished; no serum; lung apparently performing its functions well, except for a short distance above the air-tight cyst, where it was still hardened. it would seem as though nature was intending to dissolve this lump, and carry it off by absorption. she knows how, and would have done it, in the opinion of the writer, had she been allowed sufficient time. case 6.--was taken december 18th, and was very sick; in three weeks she was well, except a cough, quite severe, and so continued till about the first of march, when she coughed harder and grew worse till seven days before she was killed, april 12th, when she brought forth a calf, and then commenced improving again. autopsy.--right lung adherent to diaphragm and costal pleura. at its base, was a flabby, fluctuating cyst. in cutting into it, the lump was found to be breaking up by decomposition, and scenting badly. every thing else normal. was not the cyst broken through by some accident, thus letting in the air, when she grew worse? would she not, probably, have overcome this disagreeable accident, and recovered, in spite of it? this cow's hair did not look well, as did that of those in which the cyst was air-tight; but still she was beginning to eat well again, and appeared in a tolerable way for recovery. case 7.--this heifer had coughed slightly for six weeks, but the owner said he thought no one going into his herd would notice that any thing was the matter with her. [illustration: a rural scene.] autopsy.--slight adhesions of lung to diaphragm. near these adhesions are small cysts, of the size of a walnut, containing pus and cheesy matter; about the cysts a little way the lung was hardened, say for half an inch. there were several cysts, and they appeared as though the inflammation attacked only the different lobes of the lungs, leaving others healthy between,--nature throwing out coagulable lymph around the diseased lobe, and forming thereby an air-tight cyst, cutting around the diseased lobe by suppuration, so that it could be carried off by absorption. in the herd to which this animal belonged, nine days after the first cow died, the second case occurred. first cow was sick five weeks. the time of incubation could not have been over six weeks,--probably not over three weeks. of these cows, one improved in eight weeks, the other in three weeks. case 8.--this cow had been sick three weeks. killed. autopsy.--large quantities of serum in left chest; lung adherent, and hardened at base. on cutting into the hardened lung, one side of the lump was found separated from the lung, with pus between the lines of separation, and the forming coat of the cyst outside of the pus; the other side of the lump was part and parcel of the hardened lung which had not yet had time to commence separation. the costal pleura was covered with organized lymph to the thickness of an inch, with the usual characteristics. the right chest contained a small quantity of serum, and had several small, hardened red spots in that lung, with some tender, weak adhesions; but most of the right lung was healthy. case 9.--sick four weeks. killed. autopsy.--right lung hardened at base; adherent to diaphragm and costal pleura; lump separated on one side only. cyst beginning to form, outside of separation; pus between cyst and lump, but in a very small quantity. these two cases settle the character of the lump, and the manner of the formation of the cyst; the lump being lung and lymph, cut out by suppuration,--the cyst being organized, smoothed off by suppuration, friction, etc. case 10.--killed. hair looked badly; but the cow, it was said, ate, and appeared well. this case, however, occurred in a herd, of which no reliable information, in detail, could be procured. autopsy.--base of lung hardened, adherent to diaphragm; containing a cyst, in which was a lump, of the size of a quart measure, but little pus. this lump had air-tubes running through it, which were not yet cut off by suppuration; and in one place, the cyst was perforated by a bronchial tube, letting in the external air to the lump, which was undergoing disorganization, and swelling badly. when cut into, it did not present the red, mottled, organized appearance of those cases with air-tight cysts. quite a number of other cases were examined, but these ten present all the different phases. one or two cases are needed of an early stage of the disease, to settle the point, whether, in all cases, the primary disease is lung fever, and the pleurisy a continuation, merely, of the primary disease; together with some six or eight cases, during five, six, seven, eight months from attack, and so on till entire, final recovery. some cases were sick almost a year since, and are now apparently quite well; perhaps all the lump and pus are not yet gone. many practitioners think that no severe case will ever recover, and some think that none ever get entirely well. others, however, can see no reason why, as a general rule, all single cases should not recover, and all double cases die. the disease was the most fatal in mr. chenery's (the original) herd, although it was the best-fed and the warmest-stabled. he attributed the fatality, in part, to a want of sufficient ventilation. the other herds, in which all the fatal cases occurred in two hours, consisted, originally, one of forty-eight head, of which thirteen died, or were killed, to prevent certain death; of twenty-three head, of which seven died; of twenty-two head, of which eight died; of twenty-two head, of which eight also died; and of twenty-one head, of which four died. a little less than thirty per cent., therefore, of these herds died. this estimate excludes the calves. most of the cows which had not calved before being attacked, lost their calves prematurely. the probable time of incubation, as deduced from those massachusetts cases, is from two to three weeks; of propagation, about the same time; the acute stage of the disease lasting about three weeks. the author's attention was first directed to this disease, upon its appearance in camden and gloucester counties, new jersey, in the year 1859, at about the same time it made its advent in massachusetts. the singularity of this coincidence inclined him for the time to regard the disease as an epizoötic--having its origin in some peculiar condition of the atmosphere--rather than as a contagious, or infectious disease, which position was at that time assumed by him. this opinion was strengthened by the fact, that no case occurring in new jersey could be traced to a massachusetts origin, in which state it was claimed that the disease never had existed in this country previous to its introduction there. it was, therefore, denied by the veterinary surgeons in the eastern states, that the disease in new jersey was the true european pleuro-pneumonia, but it was called by them the swill-milk disease of new york city, and it was assigned an origin in the distillery cow-houses in brooklyn and williamsburg. in 1860 it found its way across the delaware river into philadelphia, spreading very rapidly in all directions, particularly in the southern section of the county, known as the neck,--many of the dairymen losing from one third to one half of their herds by its devastating influence. in order to save themselves--in part, at least--from this heavy loss, many of them, upon the first indications of the malady, sent their animals to the butcher, to be slaughtered for beef. in 1861 the disease found its way into delaware, where its ravages were severely felt. so soon, however, as it became known that the disease was infectious or contagious, an effort was made to trace it to its starting-point; but, in consequence of the unwillingness of dairymen to communicate the fact that their herds were affected with pleuro-pneumonia, all efforts proved fruitless. in 1860 the disease found its way up the delaware to riverton, a short distance above the city of philadelphia. a cattle-dealer, named ward, turned some cattle into a lot, adjoining which several others were grazing. the residents of this place are chiefly the families of gentlemen doing business in the city, many of whom lost their favorite animals from this destructive malady. the first case occurring at this place, to which the author's attention was called, was a cow belonging to mr. d. parrish, which had been exposed by coming in contact with ward's cattle, had sickened, and died. an anxiety having been manifested to ascertain the cause of the death, the author made an examination of the animal, which, upon dissection, proved the disease to be a genuine case of the so-called pleuro-pneumonia. this examination was made august 20th, 1860, at the time of the massachusetts excitement. two cows, belonging to mr. rose, of the same place, had been exposed, and both had taken the disease. his attention having been called to them, he placed them under the author's treatment, and by the use of diffusible stimulants and tonics, one of these animals recovered, while the other was slaughtered for an examination, which revealed all the morbid conditions so characteristic of this disease. the next case was a cow belonging to mr. g. h. roach, of the same place, which had been grazing in a lot adjoining that of mr. parrish. this cow was killed in the presence of charles wood, v.s., of boston, mass., and arthur s. copeman, of utica, n. y., who was one of a committee appointed by the new york state agricultural society for the purpose of investigating the disease. both of these gentlemen having witnessed the disease in-all its forms, as it appeared in massachusetts, were the first to identify this case with those in that state. upon opening the cow, the left lung was found to be completely consolidated, and adhered to the left side, presenting the appearance usual in such cases. as she was with calf, the lungs of the foetus were examined, disclosing a beautiful state of red hepatization. the author's attention was next called to the herd of mr. lippincott, a farmer in the neighborhood, who had lost several cattle by the disease; but as he had been persuaded that treatment was useless, he abandoned the idea of attempting to save his stock in that way. from riverton it soon spread to burlington, some ten miles farther up the river, where it carried off large numbers of valuable cattle, and it continued in existence in that neighborhood for some time. the disease was not then confined to these localities alone, but has spread over a large extent of country,--and that, too, prior to its appearance in massachusetts, as will be shown by extracts from the following letters, published in the _country gentleman_:-"we have a disease among the cattle here, i will class it under these names,--congestion of the lungs, terminating with consumption, or dropsy of the chest. now, i have treated two cases; one five years since, as congestion,--and the first is still able to eat her allowance, and give a couple of pails of milk a day,--and the other, quite recently. the great terror of this disease is, that it is not taken in its first stages, which are the same in the cow as in the man--a difficulty in breathing, which, if not speedily relieved, terminates in consumption or dropsy. i have no doubt that consumption is contagious; but is that a reason why every one taken with congestion should be killed to check the spread of consumption? so i should reason, if i had pleuro-pneumonia in my drove of cattle. j. baldwin. "newark, n. j., june 11, 1860." "i notice that a good deal of alarm is felt in different parts of the country about what is called the cattle-disease. "from the diagnosis given in the papers, i have no doubt this is pleuro-pneumonia, with which i had some acquaintance a few years ago. if it is the same, my observation and experience may be of some service to those suffering now. "it was introduced into my stock, in the fall of 1853, by one of my own cows, which, in the spring of that year, i had sent down to my brother in brooklyn, to be used during the summer for milk. she was kept entirely isolated through out the summer, and in november was sent up by the boat. there were no other cattle on the boat at the time, nor could i learn that she had come in contact with any in passing through the streets on her way to the boat; and she certainly did not, after leaving it, until she mingled with her old companions, all of whom were then, and long afterward, perfectly well. after she had been home about two weeks, we noticed that her appetite failed, and her milk fell off: she seemed dull and stupid, stood with her head down, and manifested a considerable degree of languor. "soon her breathing became somewhat hurried, and with a decided catch in it; she ground her teeth; continued standing, or, if she lay down, it was only to jump up again instantly. her cough increased, and so, too, a purulent and, bloody discharge from her nostrils and mouth. the excrement was fetid, black, and hard. "in this case, we twice administered half a pound of epsom-salts, and afterward, a bottle of castor-oil. very little, but a temporary effect was produced by these doses. "the symptoms all increased in intensity; strength diminished; limbs drawn together; belly tucked up, etc.; until the eight day, when she partly lay, and partly fell down, and never rose again. "in a _post-mortem_ examination, the lungs were gorged with black, fetid blood; the substance of them thickened and pulpy. the pleura and diaphragm also showed a good deal of disease and some adhesion. this cow, on her arrival here, was put in her usual place in the stable, between others. she remained there for two or three days after she was taken sick, before we removed her to the hospital. "in about three weeks from the time she died, one and then the other of those standing on either side of her were attacked in the same way, and with but two days between. this, certainly, looks very much like contagion; but my attention had not before been called to this particular disease, and to suppose inflammation or congestion of the lungs contagious was so opposed to my preconceived notions, that i did not even then admit it; and these animals were suffered to remain with the others until their own comfort seemed to require the greater liberty of open pens. "one of them was early and copiously bled twice, while epsom-salts were administered, both by the stomach and with the injective-pump. the other we endeavored to keep nauseated with ipecacuanha, and the same time to keep her bowels open by cathartic medicine. all proved to be of no avail. they both died,--the one in ten, the other in thirteen days. before these died, however, others were taken sick. and thus, later, i had eight sick at one time. "the leading symptoms in all were the same, with minor differences; and so, too, was the appearance after death, on examination. "of all that were taken sick (sixteen) but two recovered; and they were among those we did the least for, after we had become discouraged about trying to cure them. in all the last cases we made no effort at all, but to keep them as comfortable as we could. in one case, the acute character of the disease changed to chronic, and the animal lived six or eight weeks, until the whole texture of the lungs had become destroyed. she had become much emaciated, and finally died with the ordinary consumption. "at the time the first case appeared, i had a herd of thirty-one animals, all valuable ayrshires, in fine condition and healthy. in all the first cases, i had a veterinary surgeon of considerable celebrity and experience, and every ordinary approved method of treatment was resorted to and persevered in. the last cases--as before intimated--we only strove to make comfortable. "after i had paid the third or fourth forfeit, i began to awake up to the idea that the disease was, in a high degree, contagious, whether i would have it so or not; and that my future security was in prevention, and not in remedy. i therefore separated all the remaining animals; in no instance having more than two together, and generally but one in a place. "all were removed from the infected stalls, and put into quarantine. isolated cases continued to occur after this for some weeks, but the spread of the disease was stayed; nor did a single case occur after this, which we did not think we traced directly to previous contact. "it is impossible to account for the first case of which i have spoken. but, as the cow in that case was put into a sale-stable in new york while waiting for the boat,--though there were no cattle then present,--yet i have supposed it not unlikely that diseased animals had been there, and had left the seeds of the disease. "but, account for this case as we may,--and i have no doubt it is sometimes spontaneous,--i feel convinced it is very highly contagious; and that the only safety to a herd into which it has been introduced, is in complete isolation,--and in this i feel as convinced that there is safety. my cattle were not suffered to return to the barnyard or to any part of the cattle-barns, except as invalids were sent to 'the hospital' to die, until late the next fall, _i.e._, the fall of 1854. in the mean time, the hay and straw had all been removed; the stables, stalls, cribs and all thoroughly scrubbed with ashes and water, fumigated, and white washed with quicklime. i have had no case since, and am persuaded i should have avoided most of those i had before, if i had reasonably admitted the evidence of my senses in the second and third cases. e. p. prentice. mount hope, june 14th, 1860." the author's experience with the disease, during the last year in new jersey, proves the efficacy of remedial agents when applied in the early stages of the disease. late in the spring of 1861, mr. j. e. hancock, of burlington county (residing near columbus, n. j.), purchased some cattle in the philadelphia market, which, after they were driven home, he turned in with his other stock. soon after this purchase, one of the animals sickened and died. this was in august; after which time mr. h. lost eight cows,--having, at the time of the death of the last animal, some five others sick with the same disorder. the author was called in, december 8th, 1861, and the five animals then placed under his treatment. on the 12th of december, in the same year, one of these cows, at his suggestion, was killed, which, upon the _post-mortem_ examination, beautifully illustrated the character of the disease. the right lung was comparatively healthy; the left one completely hepatized, or consolidated, and so enlarged as to fill up the left cavity of the chest to it's utmost capacity. this lung weighed thirty pounds. there was no effusion in the chest, but there was considerable adhesion of the _pleura-costalis_ and _pleura-pulmonalis_. all the other tissues appeared to be healthy. to the remaining animals, was administered the following: aqua ammonia, three drachms; nitric ether, one ounce; pulverized gentian-root, half an ounce; mixed with one quart of water, and drenched three times a day. the last thing at night was given a teaspoonful of phosphate of lime, mixed in a little feed, or in gruel. setons, or rowels, in the dewlap are also very beneficial. under this treatment they all did well. soon after the introduction of the disease into this herd, it found its way to the herd of william hancock, a brother of the former gentleman, who had an adjoining farm. in this herd one cow died, and the disease was found by the author developed in four more cows and two oxen, all of which--with a single exception--did well under the above treatment. the disease afterward showed itself in the herd of john pope, half a mile distant, who lost nine animals by it. thursday, december 19th, was selected for the purpose of making an examination of the hancock herds; but, after some ten or twelve animals had been examined and all pronounced tainted with the disease, the owners concluded to stop the investigation, expressing themselves dissatisfied with the result, as not one of the animals examined had shown any symptoms of disease. in order to convince them of the correctness of the diagnosis, a cow was selected and destroyed, which the hancocks believed to be in perfect health. upon opening the animal, several small patches of hepatized lung were brought into view. upon making a longitudinal section of the lump, as both were involved, they presented a red, speckled appearance. all the other tissues were healthy. the symptoms in these cases were quite different from any which had been previously seen in an experience of three years with the disease in and about philadelphia, inasmuch as they were not preceded by cough; in fact, cough did not appear in many of the animals at any time during the progress of the disease. the animals looked, ate, and milked well, previously to the development of the disease, so that the owners were thrown completely off their guard by these deceptive symptoms of health. knowing the uncertain character of this disease, and wishing to stay its ravages, a suggestion was made by the author as to the propriety of having the entire herd killed for beef. this was done the more readily, as the sale of the meat is legalized in europe, it being regarded as uninjured, and therefore wholesome meat. this suggestion was acted upon, and thus these two farms were rid of this dreadful scourge at one blow. mr. a. gaskill, of mount holly, n. j., purchased a cow from one of the hancocks, for his own family use, which was sent to mr. frank lippincott's to pasture and turned in with mr. l.'s own herd. soon after, this cow sickened and died. this was soon followed by the loss of six of mr. l.'s own cattle,--three oxen, two cows, and one steer. from this herd, it was communicated to the widow lippincott's, who occupied a neighboring farm; as also to mr. cleavenger's, who lost four animals; and to mr. smith's, who had, at one time, seven animals sick; and from cleavenger's to noaknuts, who lost two cows. some two or three cows, belonging to mr. logan, in the same neighborhood, got upon the road and broke into mr. lippincott's pasture, mixing with his herd. as soon as mr. logan was informed of the fact, he isolated these cows by enclosing them in a pen at some distance from his other cattle; but they managed to break out, and mingled with his other stock. it could scarcely be expected that his herd could escape the disease, considering the exposure to which they had been subjected. the disease manifested itself in the herds of several other farmers in the country, but space will not allow a more extended notice of the subject. the treatment which has been found most successful in this country is as follows, all of which has been tested by the author upon various occasions: in the acute, inflammatory stage of the disease, give ten drops of flemming's tincture of aconite in water, every four hours, until a change takes place; follow this with aqua ammonia, three drachms; nitric ether, one ounce; pulverized gentian-root, one half an ounce; water, one quart. drench three times a day, and give, late in the evening, a tablespoonful of phosphate of lime, in a little feed, or drench with gruel. put setons, or rowels in the dewlap, so as to have a dependent opening. this course has been found very advantageous. or, the following will be found quite satisfactory; nitrate of potash, two drachms; camphor, half a drachm; tartrate of antimony, half a drachm; mix, and give in a little gruel, night and morning. or, the following: glauber-salts, four ounces; water, one pint; give twice a day. a gill of cold-drawn castor-oil, added to the above, would be beneficial. continue until the bowels are freely opened. the following has also been found efficacious: sulphate of magnesia, eight ounces; nitrate of potash and pulverized jamaica ginger-root, of each one ounce. repeat as often as may be required. apply externally the following ointment to the sides; biniodide of mercury, four drachms; castor-oil, half an ounce; lard, four ounces; mix for use. preventive measures.--1st. the complete isolation of all herds in which the disease has made its appearance. 2d. such animals as show symptoms of the disease should be placed under proper treatment. 3d. in england, it is recommended that animals recovering from the disease should be fattened and slaughtered for beef, as they are not safe even after their apparent recovery. 4th. all animals beyond medical treatment should be killed and buried; recompense in part, at least, being made to the owners. 5th. no animal, healthy or diseased, should be allowed to run at large upon the public highway so long as the disease may exist in its neighborhood. [illustration: taking it easily.] the united action of all those interested would soon rid the country of a disease which has smitten all europe. the author takes this occasion to acknowledge the receipt of two very ably written articles upon this subject, which, in consequence of their length and the comparatively limited space allotted, he is reluctantly compelled to omit. one is from the pen of r. mcclure, v.s., and the other from isaiah michener, v.s. for the benefit his readers, however, he desires to make a single extract from the last-named communication, without being considered as endorsing the opinion advanced therein:-"i am inclined to favor the hypothesis that pleuro-pneumonia is produced by animalculæ, and that these enter the lungs by myriads, and thereby set up irritation and inflammation, which lead to all the phenomena and pathological conditions which are to be found upon dissection. this is my opinion of the cause of the malignant pleuro-pneumonia which has existed in the united states for the last seven years." after writing the foregoing, the author was informed that this disease had made its appearance in mr. logan's herd, already mentioned as exposed. he was called to visit the herd of mr. g. satterthwaite, who likewise lost two cows, and had two cows and a calf sick at the time of sending for him. pneumonia. there are two conditions of the lungs known as pneumonia,--one, the inflammatory, and the other, the congestive stage. the former may follow an attack of bronchitis, or it may have a spontaneous origin. the congestive is generally the result of cold suddenly applied to an overheated animal, causing a determination of blood to the lungs, which sometimes causes death by suffocation. _symptoms._--the disease is preceded by a shivering fit; dry skin; staring coat; clammy mouth; short cough; schneiderian membrane (of the nose) very much reddened; respiration hurried or laborious. in the congestive stage, upon applying the ear to the sides, no sound will be detected; while in the inflammatory stage, a crackling or crepitating sound will be distinctively heard. _treatment._--in the congestive stage, plenty of pure air will be necessary. bleed freely; and give in drench one pound of glauber-salts, with two drachms of jamaica ginger. nothing more will be required by way of treatment. in the inflammatory stage, bleeding should seldom be resorted to, except where the animal is in full condition. apply the following blister to the sides, well rubbed in: oil of turpentine, one ounce; croton-oil, twelve drops; aqua ammonia, half an ounce; linseed-oil, four ounces; mix all together. give internally one pound of salts in drench, and follow with one of the following powders every four hours: nitrate of potash, one ounce; tartrate of antimony and pulverized digitalis leaves, of each, one drachm; mix all together, and divide into eight powders. or the following may be given with equal advantage: nitrate of potash, one and a half ounces; nitrate of soda, six ounces; mix, and divide into six powders; one to be given in wash or gruel every six hours. protrusion of the bladder. this sometimes occurs during the throes in difficult cases of parturition in cows, and the aid of a skillful veterinary surgeon is requisite to replace the inverted bladder. puerperal fever. this disease--milk fever, or dropping after calving--rarely occurs until the animal has attained mature age. the first symptoms make their appearance in from one to five or six days after parturition. it appears to be a total suspension of nervous function, independent of inflammatory action, which is suddenly developed, and, in favorable cases, as suddenly disappears. it is called dropping after calving, from its following the parturient state. _symptoms._--tremor of hind legs; a staggering gait, which soon terminates in loss of power in the hind limbs; pulse rises to sixty or eighty per minute; milk diminishing in quantity as the disease progresses; the animal soon goes down, and is unable to rise, moans piteously; eyes set in the head; general stupor; and slow respiration. _treatment._--this disease, though generally regarded as a febrile disorder, will not yield to the general practice of taking blood, as a large majority of the cases so treated die. the bowels must be opened, but the veins never. give epsom-salts, one pound; jamaica ginger, two ounces; dissolve in warm water, one quart, and drench. the author usually gives with good effect, some five or six hours after the salts, two ounces of nitric ether and one ounce of tincture of opium, in half a pint of water. rub well in, along the back and loins, the following: strong mustard, three ounces; aqua ammonia and water, each one and a half ounces. some modifications in the treatment of this disease, as well as of most others, will be necessary under certain circumstances, which can only be determined by the veterinary practitioner. quarter evil. in some sections of the country, this disease--known by the other names of black quarter, and joint murrain--is quite common among young cattle, and is generally fatal in its termination. there is little or no warning of its approach. the first animals in a herd to be attacked are generally those in a full, plethoric condition. _symptoms._--the joints suddenly become swollen, and so painful as to produce severe lameness, particularly in the hind parts. general irritative fever exists in the system, attended with great tenderness of the loins; the head is poked out; eyes red and bulging; the roots of the horns, as well as the breath, are hot; the muzzle dry, and nostrils expanded; pulse rises to seventy or eighty, full and hard; respiration is hurried; the animal is constantly moaning, and appears to be unconscious of surrounding objects; the swelling of the limbs extends to the shoulder and haunch; the animal totters, falls and dies in from twelve to twenty-four hours. _treatment._--early bleeding is requisite here, to be followed by active purgatives; after which, give one of the following powders every half hour: nitrate of potassa, two ounces; tartrate of antimony and pulverized digitalis, of each one and a half drachms; mix, and divide into eight powders. these should not be renewed. cold linseed tea should be freely given. rabies. hydrophobia in cattle is the result of the bite of a rabid dog, from which bite no animal escapes. the effects produced by the wound made by the teeth of such an animal, after the virus is once absorbed into the circulation of the blood, are so poisonous that all treatment is useless. the proper remedies must be instantly applied to prevent this absorption, or the case is utterly hopeless. among men, nine out of every ten bitten by rabid dogs escape the terrible effects resulting from this dreadful disorder, without resorting to any applications to prevent it. it is a well-established fact, that men, when bitten by dogs, are generally wounded in some part protected by their clothing, which guards them from the deleterious effects of the saliva which covers the teeth, and which, at such times, is deadly poison. the teeth, in passing through the clothing, are wiped clean, so that the virus is not introduced into the blood; hence the comparatively few cases of rabies occurring in man. when, however, the wound is made upon an exposed surface, as the flesh of the hand, or of the face, this fatal disease is developed in spite of every precaution, unless such precautions are immediately taken. for this reason, cattle when bitten, do not escape the disease. _symptoms._--the animal separates itself from the rest of the herd, standing in a kind of stupor, with the eyes half-closed; respiration natural; pulse quickened; temperature of body and limbs natural; the slightest noise agitates, causing the eyes to glare and exciting bellowing; the bark of a dog produces the most violent effects; the animal foams at the mouth and staggers as it walks; if water is offered, the muzzle is plunged into it, but the victim cannot drink; in making the effort, the most fearful consequences are produced. the animal now seeks to do mischief,--and the quicker it is then destroyed, the better. _treatment._--this must be applied quickly, or not at all. the moment an animal is bitten, that moment the wound should be searched for, and when found, should be freely opened with a knife, and lunar caustic, caustic potash, or the permanganate of potash at once applied to all parts of the wound, care being taken not to suffer a single scratch to escape. this, if attended to in time, will save the animal. red water. this disease derives its name from the color of the urine voided in it. it is one of the most common complaints of horned cattle, and one of the most troublesome to manage. _symptoms._--respiration hurried; rumination ceases; a high degree of fever presented; the animal moans, arches the back, and strains in passing the urine, which is tinged with blood, or presents the appearance of pure blood. prof. gamgee, of the edinburgh veterinary college, says: "the cause is almost invariably feeding on turnips that have grown on damp, ill-drained land; and very often a change of diet stops the spread of this disease in the byre. other succulent food, grown under similar circumstances, may produce the same symptoms, tending to disturb the digestive organs and the blood-forming process. "in the course of my investigations as to the cause of various cattle-diseases, and of red water in particular. i have found that it is unknown on well-drained farms and in dairies where turnips are used only in a moderate degree. the lands of poor people furnish the roots most likely to induce this disorder; and i can confirm the statement of the late mr. cumming, of elton, who, in his very interesting essay upon this subject, says, particularly in reference to aberdeenshire, that it is 'a disease essentially attacking the poor man's cow; and to be seen and studied, requires a practice extending into the less favorably situated parts of the country. on large farms, where good stock is well kept, and in town dairies, where artificial food is used to supplement the supply of turnips, it is seldom now seen.' "_symptoms._--general derangement attracts the dairyman's attention, and, upon observing the urine which the animal has voided, it is seen to be of a red, or of a reddish brown, or claret color; sometimes transparent, at others clear. the color increases in depth; other secretions are checked; the animal becomes hide-bound, and the milk goes off. appetite and rumination are suspended; the pulse becomes extremely feeble and frequent, though--as in all debilitating, or anæmic, disorders--the heart's action is loud and strong, with a decided venous pulse, or apparent regurgitation, in the large veins of the neck. "in some cases, if even a small quantity of blood be withdrawn, the animal drops in a fainting state. in red water, the visible mucous membranes are blanched, and the extremities cold, indicating the languid state of the blood's circulation and the poverty of the blood itself. constipation is one of the most obstinate complications; and many veterinary surgeons--aware that, if the bowels can be acted on, the animal is cured--have employed purgatives in quantities far too large, inducing at times even death. occasionally, diarrhoea is one of the first, and not of the unfavorable, symptoms." _treatment._--give one pint of linseed-oil; clysters of soap and water should be freely used; and give plenty of linseed-tea to drink. when the urine is abundant, give one ounce of tincture of opium, with one drachm of powdered aloes, three times, at intervals of six or eight hours. rheumatism. this is a constitutional inflammatory affection of the joints, affecting the fibrous tissue and serous, or synovial membrane. it is caused by exposure to cold and wet; being quite common in low, marshy sections. _symptoms._--loss of appetite; upon forcing the animal to move, every joint seems stiffened; nose dry; coat staring; constipation is also an attendant symptom; the joints, one or more, become swollen and painful. this may be regarded as a metastic, or shifting disease; first one part, and then another, seems to be affected. _treatment._--mild purgatives should be used; one-half-ounce doses of colchicum-root pulverized will be found useful; one-ounce balls of pine-tar may also be given with advantage. as a local application, the author has found nothing to equal kerosene oil, one pint, to two ounces of aqua ammonia, well rubbed in, two or three times a day. strangulation of the intestines. this disease in cattle,--popularly styled knot, or gut-tie,--in consequence of the peculiar arrangement of the abdominal viscera, is of very rare occurrence. when, however, it does occur, the symptoms accompanying are those of inflammation of the intestines. no kind of treatment will be successful, and the poor brute must suffer until death comes to its relief. thrush in the mouth. aptha, or thrush in the mouth, is a vesicular disease of the mouth, sometimes occurring as an epizoötic. it is often mistaken for blain,--inflammation of the tongue, or black tongue,--and usually occurs in the winter, or early in the spring. it appears in the form of vesicles, or pustules all over the mouth, occasionally extending to the outside of the lips. these pustules break, discharging a thin, sanious fluid, leaving minute ulcers in their places. this disease yields readily to treatment, when it is properly applied. three ounces of epsom-salts, once a day for three or four days, should be given in drench; wash the mouth well with a solution of alum, tincture of myrrh, or vinegar and honey, and it will disappear in a few days. tumors. these enlargements so common in cattle, have been so admirably described, in the veterinarian for 1843, by john ralph, v.s.,--who has been so successful in the treatment of these morbid growths, that the benefit of his experience is here given. he says: "of all the accidental productions met with among cattle, with the exception of wens, a certain kind of indurated tumor, chiefly situated about the head and throat, has abounded most in my practice. "the affection often commences in one of the thyroid glands, which slowly but gradually increases in size, feels firm when grasped, and evinces very little tenderness. generally the attendant is alarmed by a snoring or wheezing noise emitted by the animal in respiration, before he is aware of the existence of any tumefaction. this continues to increase, embracing in its progress the adjacent cellular and muscular tissues, and frequently the submaxillary and parotid glands. it becomes firmly attached to the skin through which an opening is ultimately effected by the pressure of pus from the centre of the tumor. "the swelling often presents an irregular surface, and various centres of maturation exist; but the evacuations only effect a partial and temporary reduction of its bulk, in consequence of the continued extension of the morbid growth and ulcerative process which often proceed towards the pharynx, rendering respiration and deglutition still more difficult, until at length the animal sinks from atrophy or _phthisis pulmonalis_. "in the early part of my practice, having been frustrated in my attempts to establish healthy action in these ulcers, and referring to the works that i had on surgery for information, i concluded that they bore some resemblance to cancer in the human being, and determined to attempt extirpation. subsequently, numerous cases have occurred in which i have successfully carried that determination into effect. i have had some instances of failure, which failure always arose from some portion of the morbid growth having been left. "in the first stage, i have reason to believe that the tumor may be dispersed by the general and topical use of the iodurets. after the suppuration, i have tried them in vain. "as soon as the nature of the tumor is clearly developed, i generally attempt its removal, and, when most prominent by the side of the larynx, i proceed in the following manner:--having cast the beast, turned the occiput toward the ground, and bolstered it up with bundles of straw, i proceed to make an incision through it, if the skin is free, parallel with, and over, and between the trachea and _sterno-maxillaris_, extending it sufficiently forward into the inter-maxillary spaces. if i find it firmly attached to the apex of the tumor, i then enclose it in a curvilinear incision and proceed to detach the healthy skin to beyond the verge of the tumor. "its edges being held by an assistant, the knife is directed downwards through the subcutaneous parts, and all those that exhibit the slightest change from healthy structure are removed. "by tying any considerable blood-vessel before dividing it, and by using the handle of the scalpel and the fingers in detaching the portion of the parotid gland towards the ear the hemorrhage was always inconsiderable. "the wound is then treated in the ordinary way; except that detergents and even antiseptics are often needed to arouse healthy action, and the addition of some preparation of iodine is often made to the digestive. in directing the constitutional treatment, our chief aim must be to support the animal system with plenty of gruel until rumination is restored. "i need not note that the operation should be performed after the animal has fasted some hours. "as the success of the operation depends on an entire removal of the diseased parts, and as the submaxillary and parotid glands, with important branches of nerves and blood-vessels, are often enveloped therein, we must not hesitate to remove the former, nor to divide the latter. it has occasionally happened that a rupture has been made in the oesophagus, or pharynx, during the operation. in that case, a portion of the gruel with which the animal is drenched escapes for a few days; but i always found that the wound healed by granulation, without any particular attention. "the weight of these tumors varies from a few ounces to some pounds. one that i removed from a two-year-old galloway bullock, weighed six pounds and a quarter. a considerable portion of the skin that covered it was excised and included in the above weight. it comprehended one of the parotid glands, and i had to divide the trunk of the carotid artery and jugular vein. "this affection may be distinguished from parotiditis and other _phlegmasiæ_ by the action of constitutional disturbance, and heat, and tenderness, and by the lingering progress it makes. i was once called to a bull laboring under alarming dyspnoea that had gradually increased. no external enlargement was perceptible; but on introducing my hand into the mouth, a large polypus was found hanging from the _velum palati_ into the pharynx, greatly obstructing the elevation of the epiglottis and the passage of food. after performing tracheotomy, to prevent suffocation, i passed a ligature around its pedicle in the way suggested by the old anatomist, cheselden. "a section of one of these tumors mostly displays several abscesses, with matter varying in consistency and often very fetid, enclosed in what seems to me to be fibro-cartilaginous cysts, the exterior of which sometimes gradually disappears in the surrounding more vascular abnormal growth. osseous matter (i judge from the grating of the scalpel upon it) occasionally enters into the composition of the cysts. "i have treated this affection in cattle of the long-horned, short-horned, galloway, and highland breeds; and from the number of bulls in this class of patients, have reason to conclude that they are more liable to it than the female. "about twelve months ago, i examined the head of a cow, on the right facial region of which there existed an enormous tumor, extending from the eye to the lips, and which i mistook during life for a periosteal enlargement. on cutting into it, my mistake was evident. there was scarcely a trace of the original bones beneath the mass; even those forming the nasal sinuses on that side were replaced by a formation much resembling the cysts before alluded to, and full of abscesses. the progress of the disease was decisively marked in the inferior rim of the orbital cavity, where the osseous matter was being removed, and the morbid structure deposited." ulcers about the joints. occasionally, the joints assume a tumefied appearance, generally ulcerating, and causing painful wounds. _treatment._--the application of one part of alum to two parts of prepared chalk, powdered and sprinkled upon the parts, is usually all that is required. warbles. it has been a prevalent opinion among farmers, that warbles are so many evidences of the good condition of their cattle. it must, however, be borne in mind that the warbles are the _larvæ_ of the _oestrus bovis_, which is said to be the most beautiful variety of gad-fly. this fly, judging from the objects of its attack, must be particularly choice in its selection of animals upon which to deposit its eggs, as it rarely chooses those poor in flesh, or in an unhealthy condition. from this circumstance, probably, has arisen the opinion above-mentioned. [illustration: home again.] these warbles--or _larvæ_ of the _oestrus bovis_--so nearly resemble bots in the horse--or _larvæ oestrus equi_--that, were it not for their increased size, they might readily be mistaken the one for the other. there is, however, one other difference, and that is in the rings which encircle the body; those of the former being perfectly smooth, while those of the latter are prickly, and from one third to one half smaller. the author was called, in the year 1856, to see the prize cow, pet, belonging to james kelly, of cleveland, ohio, whose extraordinary yield of butter and milk had been reported in the _ohio farmer_, a short time previous to his visit. this animal was found by him in rather poor condition; the causes of which he could only trace to the existence of these worms, comfortably located, as they were, beneath the animal's hide, and forming small tumors all along the spinal column, each being surrounded by a considerable quantity of pus. a number of these were removed by means of a curved bistoury and a pair of forceps, since which time--as he has been informed--the animal has rapidly improved, regaining her former good condition. some may urge that this is an isolated case; but an examination of cattle for themselves, will convince them to the contrary. it may be added, that two other cows, belonging to the same gentleman, were also examined at the same time,--one of them being in good condition, and the other, out of condition. from the back of the latter several of these insects were removed, since which time she also has much improved. the former was entirely free from them. these cows were all kept in the same pasture, received the same care, and were fed on the same food, and at the same time; and as the removal of these larvæ has been productive of such beneficial results, have we not a right to infer that these insects are injurious? if we go further and examine, in the spring of the year, all cattle which are subject to them, instead of finding them in the fine condition which one would naturally expect,--considering the abundance of fresh young grass whose vigorous life they may incorporate into their own,--they are out of condition, and out of spirits, with a laggard eye, a rough coat, and, in some cases, a staggering gait, as though their strength had failed in consequence. how shall such attacks be prevented? during the months of august and september this gad-fly is busily engaged in depositing its eggs. some are of the opinion that they are placed on the hairs of the animal; others, that the skin is perforated, and the egg deposited in the opening, which would account for the apparent pain manifested by cattle at and after the time of such deposit. be this as it may, it is certain that the maggot works its way into the muscular fibre of the back, and depends upon the animal's blood for the nourishment which it receives. the author has been informed, by persons in whom he ought to have confidence, that the _free use of the card_, during the above-named months, is a specific protection against the attacks of the _oestrus bovis_. he repeats this information here, not without diffidence; since so large a majority of stock-owners evince, by their lack of familiarity with the practical use of this convenient and portable instrument, an utter disbelief in its reliability and value. worms. cattle are not so subject to worms proper as are the other domestic animals; nor, when these parasites do exist, is any injurious effect apparent, except it be in the case of young calves of a weakly constitution. worms are most commonly located in the small intestines, and cause there considerable irritation, and consequently, general emaciation, or at least a tendency to it. the cause, however, is easily removed by administering doses of sulphate of iron, one-half drachm each, in molasses once or twice a day. worms in the bronchial tubes. inflammation of the bronchial tubes is often caused by worms of the _strongylus_ species. upon examination after death, the bronchial passages are completely blocked-up by these hangers-on. _symptoms._--a rough, staring coat; hide-bound; painful cough; respiration hurried, etc. _treatment._--but little can be done by way of treatment in this disease. the administration of small doses of spirits of turpentine has, in some instances, proved successful. surgical operations. castration. the period most commonly selected for this operation is between the first and third months. the nearer it is to the expiration of the first month, the less danger attends the operation. some persons prepare the animal by the administration of a dose of physic; but others proceed at once to the operation when it best suits their convenience, or that of the farmer. care, however, should be taken that the young animal is in perfect health. the mode formerly practised was simple enough:--a piece of whip-cord was tied as tightly as possible around the scrotum. the supply of blood being thus completely cut off, the bag and its contents soon became livid and dead, and were suffered to hang, by some careless operators, until they dropped off, or they were cut off on the second or third day. it is now, however, the general practice to grasp the scrotum in the hand, between the testicles and the belly, and to make an incision in one side of it, near the bottom, of sufficient depth to penetrate through the inner covering of the testicle, and of sufficient length to admit of its escape. the testicle immediately bursts from its bag, and is seen hanging by its cord. the careless or brutal operator now firmly ties a piece of small string around the cord, and having thus stopped the circulation, cuts through the cord, half an inch below the ligature, and removes the testicle. he, however, who has any feeling for the poor animal on which he is operating, considers that the only use of the ligature is to compress the blood-vessels and prevent after-hemorrhage, and, therefore, saves a great deal of unnecessary torture by including them alone in the ligature, and afterwards dividing the rest of the cord. the other testicle is proceeded with in the same way and the operation is complete. the length of the cord should be so contrived that it will immediately retract, or be drawn back, into the scrotum, but not higher, while the ends of the string hang out through the wound. in the course of about a week, the strings will usually drop off, and the wounds will speedily heal. there will rarely be any occasion to make any application to the scrotum, except fomentation of it, if much swelling should ensue. a few, whose practice cannot be justified, seize the testicle as soon as it escapes from the bag, and, pulling violently, break the cord and tear it out. it is certain that when a blood-vessel is thus ruptured, it forcibly contracts, and very little bleeding follows; but if the cord breaks high up, and retracts into the belly, considerable inflammation has occasionally ensued, and the beast has been lost. the application of _torsion_--or the twisting of the arteries by a pair of forceps which will firmly grasp them--has, in a great degree, superseded every other mode of castration, both in the larger and the smaller domesticated animals. the spermatic artery is exposed, and seized with the forceps, which are then closed by a very simple mechanical contrivance; the vessel is drawn a little out from its surrounding tissue, the forceps are turned around seven or eight times, and the vessel liberated. it will be found to be perfectly closed; a small knot will have formed on its extremity; it will retract into the surrounding surface, and not a drop more of blood will flow from it; the cord may then be divided, and the bleeding from any little vessel arrested in the same way. neither the application of the hot iron, nor of the wooden clamps, whether with or without caustic, can be necessary in the castration of the calf. a new instrument was introduced in france, some few years since, for this purpose, called the _acraseur_,--so constructed as to throw a chain over the cord, which is wound up by means of a screw working upon the chain, and at the same time the cord is twisted off. no bleeding follows this method of operating. this instrument is constructed upon the same principle as the _acraseur_ for use in the human family, for the removal of hemorrhoids, etc., the dimensions of the two only varying. the advantages resulting from the use of this instrument over all other methods are, that the parts generally heal within a week,--the operation is not so painful to the animal,--it is less troublesome to the operator,--also to the owner of the animal,--and lastly, it is a safer and more scientific operation. its success in france soon gave it a reputation in england, and recently it has been introduced by the author into this country, and with the best results. contractors, hearing of the success attending this new mode of operating, have visited him from all parts of the country to witness its performance, and not one has returned without leaving an order for this instrument,--so well convinced have they been of its decided superiority over all other methods. tracheotomy. in consequence of the formation of tumors about the throat in cattle, from inflammation of the parotid gland, blain, etc., so characteristic of this species of animals, it sometimes becomes necessary to perform this operation in order to save their lives. it never fails to give instant relief. after the animal has been properly secured,--which is done by an assistant's holding the nose with one hand, and one of the horns with the other,--the operator draws the skin tight over the windpipe with the thumb and fingers of his left hand; then, with the scalpel in his right, cuts through the skin, making an incision about three inches long, dissecting up the skin on each side, which brings the _trachea_, or windpipe, in full view. he then cuts out a piece of the cartilaginous rings, about two inches long and about half an inch wide. this simple operation has saved the lives of very many valuable animals. the wound readily heals, and seldom leaves any perceptible blemish, if the work is properly performed. spaying. to secure a more uniform flow and a richer quality of milk, cows are sometimes spayed, or castrated. the milk of spayed cows is pretty uniform in quality; and this quality will be, on an average, a little more than before the operation was performed. in instances where the results of this operation have been carefully noted,--and the operation is rarely resorted to in this country, in comparison with the custom in france and other continental countries,--the quality of the milk has been greatly improved, the yield becoming regular for some years, and varying only in accordance with the difference in the succulence of the food. the proper time for spaying is about five or six weeks after calving, or at the time when the largest quantity of milk is given. there seems to be some advantages in spaying for milk and butter dairies, where attention is not paid to the raising of stock. the cows are more quiet, never being liable to returns of seasons of heat, which always more or less affect the milk, both in quantity and quality. they give milk nearly uniform in these respects, for several years, provided the food is uniformly succulent and nutritious. their milk is influenced like that of other cows, though to a less extent, by the quality and quantity of food; so that in winter, unless the animal is properly attended to, the yield will decrease somewhat, but will rise again as good feed returns. this uniformity for the milk-dairy is of immense advantage. besides, the cow, when old and inclined to dry up, takes on fat with greater rapidity, and produces a juicy and tender beef, superior, at the same age, to that of the ox. the following method of performing this operation is sanctioned by the practice of eminent veterinary surgeons in france:-having covered the eyes of the cow to be operated upon, she is placed against a wall, provided with five rings firmly fastened and placed as follows: the first corresponds to the top of the withers; the second, to the lower anterior part of the breast; the third is placed a little distance from the angle of the shoulder; the fourth is opposite to the anterior and superior part of the lower region; and the fifth, which is behind, answers to the under-part of the buttocks. a strong assistant is placed between the wall and the head of the animal, who firmly holds the left horn in his left hand, and with his right, the muzzle, which he elevates a little. this done, the end of a long and strong-plaited cord is passed, through the ring which corresponds to the lower part of the breast, and fastened; the free end of the cord is brought along the left flank, and through the ring which is below and in front of the withers. this is brought down along the breast behind the shoulder and the angle of the fore-leg in order to pass it through the third ring; then it must be passed around against the outer angle of the left hip, and fastened after having been drawn tightly to the posterior ring, by a simple bow-knot. the cow being thus firmly fixed to the wall, a cord is fastened by a slip-noose around her hocks, to keep them together in such a manner that she cannot kick the operator, the free end of the cord and the tail being held by an assistant. the cow thus secured cannot, during the operation, move forward, nor lie down, and the operator has all the ease desirable, and is protected from accident. the operator next--placed opposite to the animal's left flank, with his back turned a little toward the head of the animal--cuts off the hair which covers the hide in the middle of the flanks, at an equal distance between the back and hip, for the space of thirteen or fourteen centimetres in circumference (the french _centimetre_ is rather more than thirty-nine one hundredths of an inch); a convex bistoury is placed, opened, between his teeth, the edge out, the joints to the left; then, with both hands, he seizes the hide in the middle of the flank, and forms of it a wrinkle of the requisite elevation, running lengthwise of the body. the assistant seizes with his right hand the right side of this wrinkle; the operator takes the bistoury and cuts the wrinkle, at one stroke, through the middle; the wrinkle having been suffered to go down, a separation of the hide is presented, of sufficient length to admit the introduction of the hand; the edges of the hide are separated with the thumb and fore-finger of the left hand, and in like manner the abdominal muscles are cut through, for the distance of a centimetre from the lower extremity of the incision made in the hide,--the _iliac_ slightly obliquely, and the _lumbar_ across; a puncture of the peritoneum, at the upper extremity of the wound, is then made with the straight bistoury; the buttoned bistoury is then introduced, and moved obliquely from above to the lower part, up to the termination of the incision made in the abdominal muscles. the flank being opened, the right hand is introduced into the abdomen, and directed along the right side of the cavity of the pelvis, behind the paunch, and underneath the rectum, to the matrix; after the position of these viscera is ascertained, the organs of reproduction, or ovaries, are searched for, which are at the extremity of the matrix; when found, they are seized between the thumb and fore-finger, detached completely from the ligaments which keeps them in their place, and by a light pull, the cord and the vessels, the uterine or fallopian tube, are separated at their place of union with the ovarium, by means of the nails of the thumb and fore-finger, which present themselves at the point of touch, thus breaking the cord and bringing away the ovary. the hand is again introduced into the abdominal cavity, and the remaining ovaries brought away in like manner. a suture is then placed of three or four double threads, waxed at an equal distance, and at two centimetres, or a little less, from the lips of the wound, passing it through the divided tissues; a movement is made from the left hand with the piece of thread; having reached that point, a fastening is made with a double knot, the seam placed in the intervals of the thread from the right, and as the lips of the wound are approached, a fastening is effected by a simple knot, with a bow, care being taken not to close too tightly the lower part of the seam, in order to allow the suppuration, which may be established in the wound, to escape. the wound is then covered up with a pledget of lint, kept in its place by three or four threads passed through the stitches, and the operation is complete. it happens, sometimes, that in cutting the muscles before mentioned, one or two of the arteries are severed. should much blood escape, a ligature must be applied before opening the peritoneal sac; since, if this precaution is omitted, blood will escape into the abdomen, which may occasion the most serious consequences. for the first eight days succeeding, the animal should have a light diet, and a soothing, lukewarm draught; if the weather should be cold, cover with a woollen covering. she must be prevented from licking the wound, and from rubbing it against other bodies. the third day after the operation, bathe morning and evening about the wound with water of mallows lukewarm, or anoint it with a salve of hog's lard, and administer an emollient glyster during three or four days. eight days after the operation, take away the bandage, the lint, the fastenings, and the thread. the wound is at that time, as a general thing, completely cicatrized. should, however, some slight suppuration exist, a slight pressure must be used above the part where it is located, so as to cause the pus to leave, and if it continues more than five or six days, emollients must be supplied by alcolized water, or chloridized, especially in summer. the animal is then to be brought back gradually to her ordinary nourishment. in some cows, a swelling of the body is observable a short time after having been spayed, attributable to the introduction of cold air into the abdomen during the operation; but this derangement generally ceases within twenty-four hours. should the contrary occur, administer one or two sudorific draughts, such as wine, warm cider, or a half-glass of brandy, in a quart of warm water,--treatment which suffices in a short time to restore a healthy state of the belly,--the animal at the same time being protected by two coverings of wool. the only precaution, in the way of management, to be observed as a preparative for the operation is, that on the preceding evening not so copious a meal should be given. the operation should also be performed in the morning before the animal has fed, so that the operator may not find any obstacle from the primary digestive organs, especially the paunch, which, during its state of ordinary fullness, might prevent operating with facility. the advantages of spaying milch-cows are thus summed up by able french writers: first, rendering permanent the secretion of milk, and having a much greater quantity within the given time of every year; second, the quality of milk being improved; third, the uncertainty of, and the dangers incident to, breeding being, to a great extent, avoided; fourth, the increased disposition to fatten even when giving milk freely, or when, from excess of age or from accidental circumstances, the secretion of milk is otherwise checked; fifth, the very short time required to produce a marketable condition; and sixth, the meat of spayed cattle being of a quality superior to that of ordinary cattle. this operation would seem to have originated in this country. the london veterinary journal of 1834 contains the following, taken from the united states southern agriculturist:--"some years since, i passed a summer at natchez, and put up at a hotel there, kept by mr. thomas winn. during the time that i was there i noticed two remarkably fine cows, which were kept constantly in the stable, the servant who had charge of the horses, feeding them regularly three times a day with green guinea grass, cut with a sickle. these cows had so often attracted my attention, on account of the great beauty of their form, and deep red color, the large size of their bags, and the high condition in which they were kept, that i was at length induced to ask mr. winn to what breed of cattle they belonged, and his reasons for keeping them constantly in the stable in preference to allowing them to run in the pasture, where they could enjoy the benefit of air and exercise, and at the same time crop their own food, and thereby save the labor and trouble of feeding them? mr. winn, in reply to these inquiries, stated that the two cows which i so much admired were of the common stock of the country, and he believed, of spanish origin; but they were both spayed cows, and that they had given milk either two or three years. considering this a phenomenon (if not in nature at least in art), i made further inquiries of mr. winn, who politely entered into a very interesting detail, communicating facts which were as extraordinary as they were novel. mr. winn, by way of preface, observed that he, in former years, had been in the habit of reading english magazines, which contained accounts of the plowing-matches which were annually held in some of the southern counties of england, performed by cattle, and that he had noticed that the prizes were generally adjudged to the plowman who worked with spayed heifers; and although there was no connection between that subject and the facts which he should state, it was, nevertheless, the cause that first directed his mind into the train of thought and reasoning which finally induced him to make the experiments, which resulted in the discovery of the facts which he detailed, and which i will narrate as accurately as my memory will enable me to do it, after the lapse of more than twenty years. mr. winn's frequent reflections had (he said) led him to the belief "that if cows were spayed soon after calving, and while in a full flow of milk, they would continue to give milk for many years without intermission, or any diminution of quantity, except what would be caused by a change from green to dry, or less succulent food." to test this hypothesis, mr. winn caused a very good cow, then in full milk, to be spayed. the operation was performed about one month after the cow had produced her third calf; it was not attended with any severe pain, or much or long continued fever. the cow was apparently well in a few days, and very soon yielded her usual quantity of milk, and continued to give freely for several years without any intermission or diminution in quantity, except when the food was scarce and dry; but a full flow of milk always came back upon the return of a full supply of green food. this cow ran in the mississippi low grounds or swamp near natchez, got cast in deep mire, and was found dead. upon her death, mr. winn caused a second cow to be spayed. the operation was entirely successful. the cow gave milk constantly for several years, but in jumping a fence stuck a stake in her bag, that inflicted a severe wound, which obliged mr. winn to kill her. upon this second loss, mr. winn had two other cows spayed, and, to prevent the recurrence of injuries from similar causes with those which had occasioned him the loss of the first two spayed cows, he resolved to keep them always in the stable, or some safe enclosure, and to supply them regularly with green food, which that climate throughout the greater part of, if not all, the year enabled him to procure. the result, in regard to the last two spayed cows, was, as in the case of the first two, entirely satisfactory, and fully established, as mr. winn believed, the fact, that the spaying of cows, while in full milk, will cause them to continue to give milk during the residue of their lives, or until prevented by old age. when i saw the last two spayed cows it was, i believe, during the third year that they had constantly given milk after they were spayed. the character of mr. winn (now deceased) was highly respectable, and the most entire confidence could be reposed in the fidelity of his statements; and as regarded the facts which he communicated in relation to the several cows which he had spayed, numerous persons with whom i became acquainted, fully confirmed his statements." in november 1861, the author was called to perform this operation upon the short-horn galloway cow, josephine the second, belonging to henry ingersoll, esq., of this city. this cow was born may 8th, 1860. the morning was cold and cloudy. about ten o'clock the cow was cast, with the assistance of r. mcclure, v.s., after which she was placed under the influence of chloric ether. he then made an incision, about five inches in length, through the skin and walls of the abdomen, midway between the pelvis bone and the last rib on the left side, passing in his right hand, cutting away the ovaries from the fallopian tubes with the thumbnail. the opening on the side was then closed by means of the interrupted suture. the animal recovered from the influence of the anæsthetic in about fifteen minutes, when she was allowed to rise, and walk back to her stall. upon the morning of the second day succeeding the operation, the animal was visited and found to be in good spirits, apparently suffering very little pain or inconvenience from the operation, and the wound healing nicely. since that time, he has operated upon some twenty cows, all of which, with a single exception, have thus far proved satisfactory. several of these cows are under the direction of a committee from the philadelphia society for promoting agriculture, whose duty it is to have a daily record kept of each cow's yield of butter and milk, for one year from the time of spaying. their report will be perused by the agricultural community with much interest. the author's own experience will not justify him in speaking either in favor of, or against, this operation; as sufficient time has not as yet elapsed to satisfy him as to its relative advantages and disadvantages. he, however, regards the operation as comparatively safe. the french estimate the loss at about fifteen per cent., and the gain at thirty per cent. of those upon which he has operated, not a single animal died. a list of medicines used in treating cattle. the medicines used in the treatment of the diseases of cattle, are essentially the same as those in vogue for the diseases of the human being and the horse,--the only difference being in their combination and the quantities administered. absorbents.--medicines which destroy acidities in the stomach and bowels; such as chalk, magnesia, etc. alteratives.--medicines which restore the healthy functions of secretion, by gradually changing the morbid action in an impaired constitution. those in most common use are æthiops mineral, antimony, rosin, sulphur, etc., which form the principal ingredients in all condition-powders, and are chiefly useful in diseases of the skin, such as hide-bound, mange, surfeit, etc. alterative powder.--sulphur pulverized, one pound; black antimony, one half a pound; nitrate of potassa, four ounces; sulphate of iron, one half a pound; linseed meal, one pound; mix well; dose, one half an ounce, night and morning. antacids.--agents which neutralize, by their chemical action, acids in the stomach; as ammonia, carbonate of potassa, chalk, lime-water, magnesia, and soda. anthelmintics.--remedies used for the expulsion of worms from the stomach and intestines. these may act chemically or by their cathartic operation. the most reliable are æthiops mineral, nux vomica, preparations of mercury, wormwood, etc. anthelmintic powders.--nux vomica, in one half-drachm doses, two or three times daily, to an ox or cow; for calves, the dose must be diminished, according to age. antidotes.--medicines which neutralize the effects of poisons by a chemical union, forming an insoluble compound, or a mild, harmless one. alkaline solutions are antidotes for the mineral acids; as soap in solution, a simple remedy, and always at hand. lard, magnesia, and oil are antidotes for poisoning by arsenic; albumen,--in the form of the white of an egg,--milk, etc., for corrosive sublimate, and other mercurial preparations. antiseptics.--medicines which prevent putridity in animal substances, and arrest putrefaction, when already existing. these are used both externally and internally. the chief specifics of this class are the acids, alcohol, ammonia, asafoetida, camphor, charcoal, chloride of lime, cinchona, ether, and opium. antispasmodics.--medicines which exert their power in allaying inordinate motions or spasms in the system, arising from various causes, such as debility, worms, etc. those most generally in use are ammonia, asafoetida, camphor, cinchona, ether, lactacarium, mercury, and opium. antispasmodic draught.--tincture of opium, one ounce; nitric ether, two ounces; water, one-half pint. mix for drench; if repeated, it should be followed by a purgative, as soon as the spasms have subsided. or, use the following: sulphuric ether, one to two ounces; water, one-half pint mix for drench; repeat every hour, if necessary. aromatics.--medicines possessing a grateful, spicy scent, and an agreeable, pungent taste; as anise-seed, cardamoms, cinnamon, cloves, ginger, etc. they are principally used in combination with purgatives, stomachics, and tonics. astringents.--medicines which serve to diminish excessive discharges, as in diabetes, diarrhoea, etc. the principal agents of this class are the acids, alum, chalk, lime-water, opium, and the sulphate of copper, lead, iron, or zinc. astringent powder.--opium, one drachm; prepared chalk, half an ounce; jamaica ginger, six drachms. mix, and divide into four powders; one to be given every hour, in a little flour gruel. or, the following: opium, one drachm; catechu, two drachms; prepared chalk, one ounce. mix, and divide into four powders; to be given as before. cardiacs.--cordials--so termed, from their possessing warm and stimulating properties--given to invigorate the system. cathartics.--medicines--also known as purgatives--which cause free evacuations of the bowels. the only purgatives used by the author in his cattle practice, as a general rule, are aloes, cream of tartar, epsom-salts, lard and linseed-oil. these answer all the indications, where purgatives are useful; indeed, no better purgative for cattle can be found than epsom-salts, combined with a carminative or aromatic drug, such as ginger. caustics.--substances which burn or destroy parts, by combining with them and causing their disorganization; used to destroy unhealthy action, or morbid growths, such as foul ulcers, foul in the foot, warts, etc. the most powerful remedial of this class is actual cauterization with a red-hot iron; caustic potash, lunar caustic, nitrous and sulphuric acids, permanganate of potash, etc., are also used. cordials.--best brandy, three ounces; orange peel, one drachm; tepid water, one pint. mix all together, for one dose. or, this for a single dose: ale, one pint; jamaica ginger, two drachms. or, the following, also a single dose: allspice, three drachms; ginger, one drachm; caraway seeds, two drachms. demulcents.--mucilaginous medicaments, which have the power of diminishing the effects of stimulating substances upon the animal system. of this class, garden rue, or marsh-mallow, gum-arabic, and gum-tragacanth are the most useful. detergents.--agents which remove foulness from ulcers. detergent powder.--prepared chalk, two ounces; alum, one ounce. mix; to be sprinkled on the part, after washing with castile-soap and water. this powder is also an admirable application for foot-rot in sheep. diaphoretics.--agents which increase the natural discharge through the pores of the skin, and in some animals induce perspiration. digestives.--medicines which promote suppuration. digestive ointment.--mix together equal portions of spirits of turpentine and lard. or, mix together with a gentle heat the following: venetian turpentine, one ounce; lard, one ounce; pulverized sulphate of copper, two drachms. or this, mixed: rosin, two ounces; spirits of turpentine, one ounce; red precipitate, one-half an ounce; lard, two ounces. diuretics.--medicines that stimulate the action of the kidneys, and augment the secretion of urine. these are very useful in swellings of the legs, or body. take of nitrate of potash and rosin, each six drachms; mix, and divide in three powders; one to be given daily. or, the following: spirits of turpentine, half an ounce; castile-soap, one ounce; jamaica ginger, one drachm; opium, one drachm. mix: and divide in two balls; one to be given each day. emollients.--medicines which relax the lining tissues, allay irritation, and soften the parts involved,--generally of a mucilaginous, or oily character. lard, linseed meal, and marsh-mallows are chiefly used. lithontriptics.--medicines possessing the power of dissolving _calculi_, or stones in the urinary passages; composed principally, according to the researches of modern chemists, of lithic or uric acid. the preparation most successfully employed by the author in such cases is muriatic acid, in doses of from one to two drachms, in a pail of water, once or twice a day. narcotics.--medicines that stupefy, and produce sleep. belladonna, camphor, hyoscyamus and opium, are among the narcotics in common use. nauseants.--agents which cause loss of appetite, and produce the sensation of vomiting, without affecting it. for this purpose, aloes, tartrate of antimony, white hellebore, etc., are used. parturients.--agents which act upon the uterus. in cases of difficult parturition, or calving, resort is occasionally had to them. ergot of rye is the most powerful. refrigerants.--cooling applications, which reduce the temperature of the blood and body; as cold water, ether, lead-water, etc. rubefacients.--medicines which gently irritate the skin, producing redness on white surfaces. of this class, are aqua ammonia, creosote, mustard, turpentine, etc. sedatives.--agents which depress the vital energies, without destroying life; as aconite, digitalis, hellebore, hydrochloric acid, hyoscyamus, opium, and tartrate of antimony. tonics.--medicines which increase the action of the muscular system, giving strength and vigor to the animal. these are among the most useful remedies known to man, and are beneficial in all cases of debility, toning up the stomach, and improving the appetite and condition of the animal. tonic powder.--pulverized gentian-root, one ounce; jamaica ginger, one half an ounce; anise-seed, six drachms. mix, and divide in eight powders; one to be given night and morning. traumatics.--medicines which excite the healing process of wounds; as aloes, friar's balsam, myrrh, rosin, sulphate of copper or zinc, tar, etc. traumatic lotion.--mix tincture of aloes, one ounce; tincture of myrrh, two ounces. or, melt together, tar, one ounce; rosin, two ounces; lard, four ounces. or, mix sulphate of zinc, one drachm; rain-water, one half pint. or, use the following, the celebrated friar's balsam; benzoin, in powder, four ounces; balsam of peru, two ounces; socotrine aloes, one half ounce; rectified spirits, one quart. digest for ten or twelve days; then filter for use. doses of various remedies used in cattle practice. aconite.--[_monk's hood_;

'so frequent are such cases that observers have concluded that their prevalence must result from some specific cause, and, not unnaturally, attention has thus been directed to the various modes of management practised in relation to the horse's foot, to the manner of shoeing, and, in particular, to the way in which the foot is prepared for the shoe.' it must be remembered, however, that although harm in the forge may frequently arise from culpable roughness or carelessness, such is not necessarily always the case, and that quite as much injury may result from careful and conscientious workmanship when it is unfortunate enough to be based upon principles wrong in themselves to commence with. it so happens, too, that shoeing, in itself a necessary evil, may be responsible for injuries in the causation of which the smith can have played no part. take, for example, the ill effects following upon the animal's attendant allowing him to carry his shoes for too long a time. in this case the natural growth of the horn carries the heel of the shoe further beneath the foot than is safe for a correct bearing; in fact, anterior to the point of inflection of the wall. the shoe, at the same time, is greatly thinned from excessive wear. result, a sharp and easily-bended piece of iron situate immediately under the seat of corn. pressure or actual cutting of the sole is bound to occur, and the animal is lamed. again, apart from the question of negligence or otherwise on the part of the smith or the animal's attendant, it must be remembered that the nailing on to the foot of a plate of iron is not giving to the animal an easier means of progression. the reverse is the case. in place of the sucker-like face of the natural horn is substituted a smooth, and, with wear, highly-polished surface. slipping and sliding attempts to gain a foothold become frequent, and strains of the tendons and ligaments follow in their wake. as, however, this treatise is not intended to deal with the art of shoeing, the reader must be referred to other works for further information. in addition to fleming's, there may be mentioned, among others, hunting's 'art of horse shoeing,' and the very excellent volume of messrs. dollar and wheatley on the same subject. leaving the forge, we may next look to the nature of the animal's work, and the conditions under which he is kept, for active causes in the production of disorders of the foot. from the yielding softness of the pasture he is called to spend the bulk of his time upon the hard macadamized tracks of our country roads, or the still more hard and more dangerous asphalt pavings or granite sets of our towns. the former, with the bruises they will give the sole and frog from loose and scattered stones, and the latter, with the increased concussion they will entail on the limb, are active factors in the troubles with which we are about to deal. upon these unyielding surfaces the horse is called to carry slowly or rapidly, as the case may be, not only his own weight, but, in addition, is asked to labour at the hauling of heavy loads. the effects of concussion and heavy traction combined are bound primarily to find the feet, and such diseases as side-bones, ringbones, corns, and sand-cracks commence to make their appearance. again, as opposed to the comparative healthiness of the surroundings when at grass, consideration must be given to the chemical changes the foot is frequently subjected to when the animal is housed. only too often the bedding the animal has to stand upon for several hours of the twenty-four can only be fitly described as 'filthy in the extreme.' the ammoniacal exhalations from these collected body-discharges must, and do, have a prejudicial effect upon the nature of the horn, and, though slow in its progress, mischief is bound sooner or later to occur in the shape of a weakened and discharging frog, with its concomitant of contracted heels. lucky it is in such a case if canker does not follow on. observers, too, have chronicled the occurrence in horse's feet of disease resulting from the use of moss litter. tenderness in the foot is first noticeable, which tenderness is afterwards followed by a peculiar softening of the horn of the sole and the frog. what should be a dense, fairly resilient substance is transformed into a material affording a yielding sensation to the fingers not unlike that imparted by a soft indiarubber, and as easily sliced as cheese-rind. lastly, though the foot is extremely liable to suffer from the effects of extreme dryness or excessive humidity, especially with regard to the changes thus brought about in the nature of the horn, it is perforce exposed at all times to the varying condition of the roads upon which it must travel. the intense dryness of summer and the constant damp of winter, each in their turn take part in the deteriorating influences at work upon it. though this subject might be indefinitely prolonged, this brief résumé of the adverse circumstances to which the foot of the horse is exposed is sufficient to point out the extreme importance of its study to the veterinary surgeon. so long as the horse is used as a beast of burden so long will this branch of veterinary surgery offer a wide and remunerative field of labour. chapter ii regional anatomy considered from a zoological standpoint, the foot of the horse will include all those parts from the knee and hock downwards. for the purposes of this treatise, however, the word foot will be used in its more popular sense, and will refer solely to those portions of the digit contained within the hoof. when, in this chapter on regional anatomy, or elsewhere, the descriptive matter or the illustrations exceed that limit, it will be with the object of observing the relationship between the parts we are concerned with and adjoining structures. taking the limit we have set, and enumerating the parts within the hoof from within outwards, we find them as follows: a. the bones.--the lower portion of the second phalanx or os coronæ; the third phalanx, os pedis, or coffin bone; and the navicular or shuttle bone. b. the ligaments.--the ligaments binding the articulation. c. the tendons.--the terminal portions of the extensor pedis and the flexor perforans. d. the arteries. e. the veins. f. the nerves. g. the complementary apparatus of the os pedis. h. the keratogenous membrane. i. the hoof. a. the bones. the second phalanx, os coronæ, or small pastern bone.--this belongs to the class of small bones, in that it possesses no medullary canal. it is situated obliquely in the digit, running from above downwards and from behind to before, and articulating superiorly with the first phalanx or os suffraginis, and inferiorly with the third phalanx and the navicular bone. [illustration: fig. 1.--the bones of the phalanx. 1, the os suffraginis; 2, the os coronæ; 3, the os pedis; 4, the navicular bone, hidden by the wing of the os pedis, is in articulation in the position indicated by the barbed line.] [illustration: fig. 2.--second phalanx or os coronæ (anterior view). 1, anterior surface; 2, superior articulatory surface; 3, inferior articulatory surface; 4, pits for ligamentous attachment.] [illustration: fig. 3.--second phalanx or os coronæ (posterior view). 1, posterior surface; 2, gliding surface for passage of flexor perforans; 3, lower articulatory surface.] cubical in shape, it is flattened from before to behind, and may be described as possessing six surfaces: _an anterior surface_, covered with slight imprints; _a posterior surface_, provided above with a transversely elongated gliding surface for the passage of the flexor perforans; _two lateral surfaces_, each rough and perforated by foraminæ, and each bearing on its lower portion a thumb-like imprint for ligamentous attachment, and for the insertion of the bifid extremity of the perforatus tendon; _a superior surface_, bearing two shallow articular cavities, separated by an antero-posterior ridge, for the accommodation of the lower articulating surface of the first phalanx; _an inferior surface_, also articulatory, which in shape is obverse to the superior, bearing two unequal condyles, separated by an ill-defined antero-posterior groove, which surface articulates with the os pedis and the navicular bone. _development_.--the bone usually ossifies from one centre, but often there is a complementary nucleus for the upper surface. the third phalanx, os pedis, or coffin bone.--this also belongs to the class of short bones. it forms the termination of the digit, and, with the navicular bone, is included entirely within the hoof. for our examination it offers _three surfaces_, _two lateral angles_, and _three edges_. _the anterior or laminal surface_, following closely in contour the wall of the hoof, is markedly convex from side to side, nearly straight from above to below, and closely dotted with foraminæ of varying sizes. on each side of this surface is to be seen a distinct groove, the _preplantar groove_, or _preplantar fissure_, which, commencing behind, between the basilar and retrossal processes, runs horizontally forwards from the angles or wings of the bone, and terminates anteriorly in one of the larger foraminæ. as the name 'laminal' indicates, it is this surface which in the fresh state is covered by the sensitive laminæ. _the inferior or plantar surface_, hollowed in the form of a low arch, presents for our inspection two regions, an anterior and a posterior, divided by a well-marked line, the _semilunar crest_, which extends forward in the shape of a semicircle. the anterior region, as is the laminal surface, is covered with foraminæ; in this case more minute. in the recent state it is covered by the sensitive sole. the posterior region, lying immediately behind the semilunar crest, shows on each side of a median process a large foramen, the _plantar foramen_. from this foramen runs the _plantar groove_, a channel, bounded above by the superior edge, and below by the semilunar crest of the bone, which conducts the plantar arteries into the _semilunar sinus_, a well-marked cavity in the interior of the bone. _the superior or articular surface_ consists of two shallow depressions, divided by a slight median ridge. its posterior part shows a transversely elongated facet for articulation with the navicular bone. _the superior edge_, outlining the superior margin of the laminal surface, describes a curve, with the convexity of the curve forward. in the centre of the curve is a triangular process, the _pyramidal process_, which serves as the point of attachment of the extensor pedis. _the inferior edge_, the most extensive of the three, separates the laminal from the solar surface. it is semicircular in shape, sharp, and finely dentated, and is perforated by eight to ten large foraminæ. _the posterior edge_, very slightly concave, divides the small, transversely elongated facet of the superior surface from the posterior region of the inferior surface. _the lateral angles_ of the bone, also termed the _wings_, are two projections directed backwards. each is divided by a cleft into an upper, the _basilar process_, and a lower, the _retrossal process_. in old animals the posterior portion of the cleft separating the two processes gradually becomes filled in with bony deposit, thus transforming the cleft into a foramen, which gives passage to the preplantar artery. we may mention in passing that the lateral angles give attachment to the lateral fibro-cartilages, and that the lateral angles themselves in old horses become increased in size owing to ossification of portions of the adjacent lateral cartilages. _development_.--the os pedis ossifies from two centres, one of which is for the articular surface; but this epiphysis fuses with the rest of the bone before birth. [illustration: fig. 4.--third phalanx or os pedis (postero-lateral view). 1, anterior or laminal surface; 2, preplantar foramen; 3, preplantar groove; 4, basilar process of the wing; 5, retrossal process of the wing; 6, foramen caused by the ossifying together posteriorly of the basilar and retrossal processes.] [illustration: fig. 5.--third phalanx or os pedis (viewed from below). 1, plantar surface; 2, plantar foramen and plantar groove; 3, semilunar crest; 4, tendinous surface; 5, retrossal processes of the wings.] the navicular bone, shuttle bone, or small sesamoid.--placed behind the articulating point of the second and third phalanges, this small shuttle-shaped bone assists in the formation of the pedal articulation. it is elongated transversely, flattened from above to below, and narrow at its extremities. in it we see two surfaces, and two borders. _the superior or articular surface_ of the bone, which may easily be recognised by its smoothness, is moulded upon the lower articular surface of the second phalanx, being convex in its middle, and concave on either side. _the inferior or tendinous surface_ resembles the preceding in form, but is broader and less smooth. in the recent state it is covered with fibro-cartilage for the passage of the flexor perforans. _the anterior border_ possesses above a small transversely elongated facet for articulation with the os pedis, and below a more extensive grooved portion, perforated by numerous foraminæ, affording attachment to the interosseous ligaments of the articulation. _the posterior border_, thick in the middle, but thinner towards the extremities, is roughened for ligamentous attachment. _development_.--the bone ossifies from a single centre. b. the ligaments. the articulation of the first with the second phalanx, or the pastern joint.--adhering to the limit we have set, this articulation should not receive our attention. as, however, we shall in a later page be concerned with fractures of the os coronæ, which fractures may affect the articulation above mentioned, a brief note of its formation will not be out of place. it is an imperfect hinge-joint, permitting of extension and flexion, allowing the first phalanx to pivot on the second, and admitting of the performance of slight lateral movements. it is formed by the opposing of the inferior surface of the os suffraginis with the superior surface of the os coronæ. the articulating surface of the os coronæ is supplemented by the addition behind of a thick piece of _fibro-cartilage (the glenoid_) attached inferiorly to the posterior edge of the upper articulatory surface of the os coronæ, and superiorly by means of three fibrous slips on each side to the os suffraginis. the innermost of these three slips becomes attached to about the middle of the lateral edge of the suffraginis, and the remaining two, beneath the first, attach themselves to nearer the lower end of that bone. the posterior surface of the complementary cartilage forms a gliding surface for the passage of the perforans. [illustration: fig. 6.--the navicular bone (viewed from below). 1, inferior surface (smooth for the passage of the flexor perforans); 2, anterior edge of inferior surface; 3, posterior edge of inferior surface.] [illustration: fig. 7.--the navicular bone (viewed from above, the bone tilted posteriorly to show its anterior border). 1, superior articulatory surface; 2, anterior border (grooved portion of); 3, anterior border (articulatory portion of).] [illustration: fig. 8.--ligaments of the first and second interphalangeal articulations (viewed from the side). (after dollar and wheatley.) 1, outermost slip from the glenoidal fibro-cartilage; 2, lateral ligament of the first interphalangeal articulation; 3, prolongations of the lateral ligament of the first interphalangeal articulation attached to the end of the navicular bone to form the postero-lateral ligament of the pedal joint; 4, end of the navicular bone; 5, antero-lateral ligament of the pedal joint.] _the lateral ligaments_.--these are large and thick, an outer and an inner, running obliquely from above downwards and backwards. each is inserted superiorly into the lateral tubercle of the lower end of the first phalanx, and inferiorly to the side of the second phalanx, their most inferior fibres becoming finally fixed to the extremities of the navicular bone, where they form the postero-lateral ligaments of the pedal articulation. in front of the joint the extensor pedis plays the part of an additional ligament. _the synovial membrane_.--this is limited in front by the tendon of the extensor pedis, on each side by the lateral ligaments of the joint, and behind by the glenoid fibro-cartilage. at this point it is prolonged upwards as a pouch behind the lower extremity of the first phalanx. the articulation of the second phalanx with the third, the pedal, or the coffin joint.--this also is an imperfect hinge-joint, permitting only of flexion and extension, which movements are more restricted than in the previous articulation. three bones enter into its formation: the second phalanx, the third phalanx, and the navicular bone. the lower articulatory surface is formed by the third phalanx and the navicular bone combined. to effect this the navicular is closely and firmly attached to the third phalanx by an interosseous ligament. the two bones, as one, are then connected to the second phalanx by four lateral ligaments, an anterior and a posterior on each side. _the interosseous ligament_ consists of extremely short fibres running from the extensively grooved portion of the anterior surface of the navicular bone to become attached to the os pedis immediately behind its articular surface. _the antero-lateral ligaments_ are attached by their superior extremities to the lateral surfaces of the second phalanx, and by their inferior extremities into the depressions on either side of the pyramidal process of the os pedis. _the postero-lateral ligaments_.--as mentioned when describing the first interphalangeal articulation, these are in reality continuations of the lateral ligaments of that joint. running obliquely downwards and backwards from their point of attachment to the first phalanx they curve round the lower part of the side of the second phalanx and end on the extremities and posterior surface of the navicular bone. having reached that position, they send short attachments to the retrossal process of the os pedis and to the inner face of the lateral cartilage. [illustration: fig. 9.--ligaments of the first and second interphalangeal articulations (viewed from behind). (after dollar and wheatley.) 1, suspensory ligament; 2, innermost slip from complementary cartilage of pastern joint; 3, middle slip from complementary cartilage of pastern joint; 4, outermost slip from complementary cartilage of pastern joint; 5, glenoid or complementary cartilage of pastern joint; 6, postero-lateral ligaments of the pedal joint; 7, the navicular bone; 8, interosseous ligaments of the pedal joint; 9, semilunar crest of os pedis; 10, plantar surface of os pedis.] _synovial membrane_.--this extends below the facets uniting the navicular to the pedal bone, and offers for consideration two sacs. a large one posteriorly running up behind the second phalanx to nearly adjoin the sesamoidean bursæ, and a small one, a prolongation of the synovial membrane between the antero-lateral and postero-lateral ligaments of the same side. this latter is often distended, and on account of its close proximity to the seat of operation, is liable to be accidentally opened in excision of the lateral cartilage for quittor. c. the tendons in order to convey an intelligent understanding of the tendons it will be wise to briefly describe the course of their parent muscles from their commencement. the extensor pedis.--the extensor pedis arises from the lower extremity of the humerus in two distinct portions of unequal size, a muscular and a tendinous. these are succeeded by two tendons passing in common through a vertical groove at the lower end of the radius. lower in the limb these tendons separate, the outer and smaller joining the tendon of the extensor suffraginis, and the inner and main tendon continuing its course downwards. with the exception of the navicular, it is attached to all the bones of the foot, and is covered internally by the capsular ligaments of the joints over which it passes, those with which we are concerned being the pastern joint and the pedal joint. before its attachment to the os pedis it receives on each side of the middle of the first phalanx reinforcement in the shape of a strong band descending obliquely over the fetlock from the suspensory ligament. widening out in fanlike fashion, it is inserted into the pyramidal process of the os pedis. _action_.--the action of this muscle is to extend the third phalanx on the second, the second on the first, and the first on the metacarpus. it also assists in the extension of the foot on the forearm. [illustration: fig. 10.--the flexor tendons and extensor pedis. (after haübner.) 1, tendon of flexor perforans; 2, its supporting check-band from the posterior ligament of the carpus; 3, tendon of the flexor perforatus; 4, ring and sheath of the flexor perforatus; 5, widening out of the flexor perforatus to form the plantar aponeurosis; 6, suspensory ligament; 7, reinforcing band from the suspensory ligament to the extensor pedis; 8, the extensor pedis.] the flexor pedis perforatus, or the superficial flexor of the phalanges.--in common with the perforans, this muscle arises from the inner condyloid ridge of the humerus. it is reinforced at the lower end of the radius by the superior carpal ligament, passes through the carpal and metacarpo-phalangeal sheaths, and, arriving behind the fetlock, forms a ring for the passage of the flexor perforans. its termination is bifid, and it is inserted on either side to the lateral surface of the second phalanx. [illustration: fig. 11.--the flexor perforans and flexor perforatus tendons. the metacarpo-phalangeal sheath and the ring of the perforatus laid open posteriorly, and the cut edges reflected to show the passage of the perforans. 1, reflected cut edges of the perforatus ring and the metacarpo-phalangeal sheath; 2, the perforans tendon; 3, point of insertion of the perforans tendon into the semilunar crest of the os pedis (this widened and thickened extremity of the perforans is known as the plantar aponeurosis).] [illustration: fig. 12.--the flexor perforatus and flexor perforans tendons. the metacarpo-phalangeal sheath and the ring of the perforatus laid open posteriorly, and the cut edges reflected; the flexor perforans cut through at about the region of the sesamoids, and its inferior portion deflected. 1, superior end of severed perforans tendon; 2, inferior end of severed perforans tendon; 3, insertion of flexor perforans into semilunar crest of os pedis; 4, the cut and reflected edges of the metacarpo-phalangeal sheath and perforatus ring; 5, the bifid insertion of the flexor perforatus into the lateral surfaces of the os corona; 6, the capsular ligament of the pedal joint; 7, the navicular bone; 8, the posterior surface and glenoid fibro-cartilage of the os coronæ.] _action_.--this muscle flexes the second phalanx on the first, the first on the metacarpus, and the entire foot on the forearm. mechanically, it acts as a stay when the animal is standing by maintaining the metacarpo-phalangeal angle. [illustration: fig. 13.--median section of foot. _a_, os suffraginis; _b_, os coronæ; _c_, os pedis; _d_, navicular bone; _e_, tendon of the extensor pedis; _f_, insertion of the extensor pedis into

the os coronæ; _k_, its final insertion into the semilunar crest of os pedis; _a_, section of coronary cushion; _b_, section of plantar cushion; _c_, semilunar sinus of os pedis.] the flexor pedis perforans, or the deep flexor of the phalanges.--this muscle consists of three easily-divided portions: an ulnar, a humeral, and a radial, and has for points of origin the olecranon process of the ulna, the inner condyloid ridge of the humerus, and the posterior surface of the radius. these portions are continued by a common tendon which enters the carpal sheath with the tendon of the perforatus, and continues with it through the synovial sheath of the metacarpo-phalangeal region. like the last-named tendon, it receives a supporting check-band, in this case from the posterior ligament of the carpus. passing down between the suspensory ligament in front, and the perforatus tendon behind, it glides over the sesamoid pulley and passes through the ring formed by the perforatus. continuing its course, it passes between the bifurcating portions of the extremity of the perforatus, glides over the smooth posterior surface of the supplementary glenoid cartilage of the articulation of the first and second phalanges, plays over the inferior surface of the navicular bone, and finally becomes inserted into the semilunar crest of the os pedis. on reaching the posterior border of the navicular bone it widens out to form the plantar aponeurosis. in connection with the lower portion of this tendon must be noticed the navicular sheath. this is a synovial sheath lining the deep face of the tendon, and reflected on to the navicular bone and the interosseous ligament of the pedal joint. this will be of particular interest when we come to deal with cases of pricked foot from picked up nails. above, it is in connection with the synovial membrane of the pedal articulation and that of the metacarpo-phalangeal sheath. _action_.--the action of the perforans is to flex the third on the second, and the second on the first phalanx. the latter it flexes in turn on the metacarpus. it also assists in the flexion of the entire foot on the forearm, and in supporting the angle of the metacarpo-phalangeal articulation when the animal is standing. d. the arteries. so far as the arteries supplying the foot are concerned, we shall be interested in following up the distribution of the two digitals, which are the terminal branches of the large metacarpal. the large metacarpal, or collateral artery of the cannon.--this, the larger terminal branch of the posterior radial artery, needs brief mention, for the reason that we shall be afterwards concerned with it in the operation of neurectomy. its point of origin is the inside of the inferior extremity of the radius. descending in company with the flexor tendons, and passing behind the carpus and beneath the carpal sheath, it continues its descent, in company with the internal plantar nerve and the internal metacarpal vein, on the inner side of the flexor tendons until just above the fetlock. at this point it bifurcates into the digital arteries. from the carpus downwards the large metacarpal artery, the internal metacarpal vein, and the internal plantar nerve are in close relation with each other. the vein holds the anterior position. the artery is between the two, and has the nerve in close contact with it behind. the digital arteries, or collateral arteries of the digit.--these are of large volume, and carry the blood to the keratogenous apparatus of the foot. they separate from each other at an acute angle, and pass over the side of the fetlock, one to the inside, the other to the outside, to reach the internal face of the basilar process of the os pedis, where they bifurcate to form the _plantar_ and _preplantar_ arteries. in the whole of their course the digital arteries follow the flexor tendons, and are related in front to the digital vein, and behind to the posterior branch of the plantar nerve. this is the nerve implicated in the lower operation of neurectomy, and its relation to adjoining structures will be detailed under section f. of this chapter. during its course the digital artery gives off branches in the following positions: 1. _at the fetlock_ numerous branches to the metacarpo-phalangeal articulation, the sesamoid sheath, and the tendons. 2. _at the upper extremity of the first phalanx_ branches for the supply of the surrounding tissues, and for the tissues of the ergot. 3. _towards the middle of the third phalanx_, the _perpendicular_ artery of percival. this arises at a right angle from the main vessel, and immediately divides into two series of ramifications--an ascending and a descending. the ramifications of these series freely anastomose with corresponding vessels of the opposite side. 4. _at the superior border of the lateral cartilage_, the _artery of the plantar cushion_. this is directed obliquely downwards and backwards, under cover of the cartilage, and is distributed to the middle portion of the complementary apparatus of the os pedis, as well as to the villous tissue and the coronet. a branch of it is turned forwards to join with the coronary circle in forming the _circumflex artery of the coronet_. [illustration: fig. 14.--the arteries of the foot. the digital; 2, the perpendicular--(_a_) its ascending branch, (_b_) its descending branch; 3, circumflex artery of coronary cushion; 4, the preplantar (ungual) artery--this is seen issuing from the preplantar foramen, and distributing numerous ascending (_c_) and descending (_d_) branches (the latter concur in forming the circumflex artery of the toe); 5, the circumflex artery of the toe; 6, at the point marked (*) the terminal branch of the digital--namely, the plantar ungual--is hidden behind the lateral cartilage; 7, the lateral cartilage.] 5. _under the lateral cartilage_ two transverse branches, an anterior and a posterior, to form the _coronary circle_. the numerous ramifications of these branches anastomose both anteriorly and posteriorly with their corresponding branches of the artery of the opposite side. this circle closely embraces the os coronæ. among the larger branches given off from its anterior portion are two descending, one on each side of the extensor pedis, to assist in the formation of the _circumflex artery of the coronary cushion_. the formation of this last-named artery is completed posteriorly by the before-mentioned branch from the artery of the plantar cushion. the preplantar (ungual[a]) artery.--this, the smaller of the two terminal branches of the digital, is situated inside the basilar process of the os pedis. it turns round this to gain the fissure between the basilar and retrossal processes, and becomes lodged in the preplantar fissure. here it terminates in several divisions which bury themselves in the os pedis. before leaving the inner aspect of the pedal wing it supplies a deep branch to the heel and the villous tissue. gaining the outer aspect of the wing, it distributes a further backward branch, which passes behind the circumflex artery of the pedal bone, and, during its passage in the preplantar fissure, gives off ascending and descending branches, which ramify in the laminal tissue. the plantar (ungual[a]) artery.--this, the larger of the two terminals of the digital, may be looked upon as a continuation of the main vessel. running along the plantar groove, it gains the plantar foramen. here it enters the interior of the bone (the semilunar sinus) and anastomoses with the corresponding artery of the opposite side. the circle of vessels so formed is called the _plantar arch_ or the _semilunar anastomosis_. [footnote a: the epithet 'ungual' is added by chauveau to distinguish these arteries from the properly so-called plantar arteries--the terminal divisions of the posterior tibial artery.] from the semilunar anastomosis radiate two main groups of arterial branches, an ascending group and a descending one. the _ascending_ branches penetrate the substance of the os pedis, and emerge by the numerous foraminæ on its laminal surface. the _descending_ branches, larger in size, also penetrate the substance of the pedal bone, and emerge in turn from the foraminæ cribbling its outer surface--in this case the set of larger foraminæ opening on its inferior edge. having gained exit from the bone, their frequent anastomosis, right and left, with their fellows forms a large vessel following the contour of the inferior edge of the os pedis. this constitutes the _circumflex artery of the toe_. e. the veins. these commence at the foot with a series of plexuses, which may be described as forming (1) an internal or intra-osseous venous system, and (2) an external or extra-osseous venous system. 1. the intra-osseous venous system.--this is a venous system within the structure of, and occupying the semilunar sinus of the os pedis. it follows in every respect the arrangement of the arteries as before described in the same region. efferent vessels emerge from the plantar foraminæ, follow the plantar fissures, and ascend within the basilar processes of the os pedis. here they lie under shelter of the lateral cartilages, and assist in the formation of the deep layer of the coronary plexus of the extra-osseous system. 2. the extra-osseous venous system.--this may be regarded as a close-meshed network enveloping the whole of the foot. although a continuous system, it is best described by recognising in it three distinct parts: _(a) the solar plexus_. _(b) the podophyllous plexus_. _(c) the coronary plexus_. _(a) the solar plexus_.--the veins of this plexus discharge themselves in two directions: (1) _by a central canal_ or canals running along the bottom of the lateral lacunæ of the plantar cushion to gain the deep layer of the coronary plexus. (2) _by the circumflex or peripheral vein of the toe_, a canal formed by ramifications from the solar and the podophyllous plexuses, and following the direction of the artery of the same name. the circumflex vein terminates by forwarding branches to concur in the formation of the superficial coronary plexus. _(b) the podophyllous or laminal plexus_.--the podophyllous veins anastomose below with the circumflex vein of the solar plexus, and above with the veins of the coronary plexus. _(c) the coronary plexus_.--this proceeds from the podophyllous, the intra-osseous, and the solar networks, and consists of a _central_ and _two lateral parts_. the _central_ portion lies between the lateral cartilages and immediately under the coronary cushion. the _lateral portions_ are ramifications on both surfaces of the lateral cartilages. the ramifications on the lateral cartilages may be again distinguished as _superficial_ and _deep_. the superficial layer is distributed over the external face of the cartilage, forming thereon a dense network, and finally converges towards the superior limit of the plexus to form ten or twelve principal branches, which again unite to form two large vessels. these vessels, by their final fusion at the lower end of the first phalanx, constitute the digital vein. the deep layer is formed, as before described, by ascending branches from the posterior parts of the podophyllous and solar plexuses, and by branches from the intra-osseous system of the pedal bone. the veins of this deep layer finally drain into the two vessels proceeding from the superficial layer, which go to the formation of the digital vein. the digital veins--these arise from the network formed on the surfaces of the lateral cartilages, and ascend in front of the digital arteries to unite above the fetlock, where they form an arch between the deep flexor and the suspensory ligament. from this arch (named the _sesamoidean)_ proceed the metacarpal veins. the metacarpal veins.--three in number, they are distinguished as an _internal_ and an _external metacarpal_, and a _deep_ or _interosseous metacarpal_. as we shall be concerned with these in the higher operation of neurectomy, we may give them brief mention. the internal metacarpal vein, the largest of the three, has relations with the internal metacarpal artery and the internal plantar nerve. these relations were shortly discussed under the section devoted to the arteries, to which the reader may refer. the external metacarpal vein.--this ascends on the external side of the flexor tendons in company with the external plantar nerve. _the interosseous vein_.--this is an irregular vessel running up between the suspensory ligament and the posterior face of the large metacarpal bone. f. the nerves. the plantar nerves.--these are two in number, and are distinguished as internal and external. the internal plantar nerve lies behind and in close contact with the great metacarpal artery during that vessel's course down the region of the cannon. a point of interest is that it gives off at about the middle of the cannon a branch which bends obliquely downwards and behind the flexor tendons to join its fellow of the opposite side--namely, the external plantar. this it joins an inch or more above the bottom of the splint bone. measured in a straight line, this is about 2-1/2 inches below its point of origin. near the fetlock, at the level of the sesamoids, the internal plantar nerve ends in several digital branches. the external plantar nerve.--this holds a position to the outside of the metacarpal region, analogous to that of the internal plantar nerve on the inside of the limb, running down on the external edge of the flexor tendons. unlike the internal nerve, it is accompanied by a single vessel only, the external metacarpal vein, behind which it lies. at the level of the sesamoid bones it divides, as does the _internal_ nerve, into three main branches--the digital nerves. [illustration: fig. 15.--the veins and nerves of the foot. 1, the digital vein; 2, its main tributaries, draining the podophyllous plexus, and concurring to form the digital; 3. the digital artery (the main trunk only of this is shown, in order to show its relationship with the vein and nerve); 4, the plantar nerve, with its three branches--(_a_) the anterior digital, (_b_) the middle digital, (_c_) the posterior digital; 5, the podophyllous plexus; 6, superficial portion of the coronary plexus; 7, the peripheral or circumflex vein of the toe.] the digital nerves.--these are distinguished as anterior, middle, and posterior. _the anterior branch_ descends in front of the vein, distributing cutaneous branches to the front of the digit, and terminating in the coronary cushion. _the middle branch_ descends between the artery and the vein, and freely anastomoses with the two other branches. it terminates in the coronary cushion and the sensitive laminæ. _the posterior branch_.--this is the largest of the three, and may be regarded as the direct continuation of the plantar. at the fetlock it is placed immediately above the digital artery, but afterwards takes up a position directly behind that vessel. together with the digital artery it descends to near the basilar process of the os pedis. here it passes with the plantar artery into the interior of the os pedis, and continues its main branch, with the preplantar artery, in the fissure of the same name, to finally furnish supply to the os pedis and the sensitive laminæ. it is this nerve which is divided in the low operation of neurectomy. beyond the fact of this branch descending, in the region of the pastern, 1 inch behind the digital artery, a further point of interest presents itself to the surgeon, and one to which attention must be paid. this is the presence in close proximity to the nerve of the ligament of the pad (percival), or the ligament of the ergot (mcfadyean). this is a subcutaneous glistening cord originating in the ergot of the fetlock, passing in an oblique direction downwards and forwards, and crossing over on its way both the digital artery and the posterior branch of the digital nerve. in the foregoing description of the anatomy, we have taken the fore-limb as our guide. in the hind-limb, where they reach the foot, the counterparts of the tendons, arteries, veins, and nerves differ in no great essential from their fellows in the fore. they will therefore need no special mention. g. the complementary apparatus of the os pedis. this consists of two lateral pieces, the lateral cartilages or _fibro-cartilages_ of the pedal bone, united behind and below by the _plantar cushion_. 1. the lateral cartilages.--each is a flattened plate of cartilage, possessing two faces and four borders separated by four angles. the external face is convex, covered by a plexus of veins, and slightly overhangs the pedal bone. the internal face is concave, and covers in front the pedal articulation and the synovial sac, already mentioned as protruding between the anteroand postero-lateral ligaments of that joint. we have already remarked that this is a point of interest to be remembered in connection with the operation for quittor. below and behind, the internal face of the cartilage is united to the plantar cushion. [illustration: fig. 16.--external face of the outer lateral cartilage. 1, external face of cartilage--(_a_) its upper border, (_b_) its posterior border, (_c_) its anterior border, (_d_) its inferior border; 2, the os pedis; 3, wing of os pedis.] the upper border, sometimes convex, sometimes straight, is thin and bevelled, and may easily be felt in the living animal. it is this border that the digital vessels cross to gain the foot, and the border is often broken by a deep notch to accommodate them. the inferior border is attached in front to the basilar and retrossal processes, behind which it blends with the plantar cushion. the posterior border is oblique from before to behind, and above to below, and joins the preceding two. the anterior border is oblique in the same direction, and is intimately attached to the antero-lateral ligament of the pedal articulation. the cartilages of the fore-feet are thicker and more extensive than those of the hind. 2. the plantar cushion on fibro-fatty frog.--composed of a fibrous meshwork, in the interstices of which are lodged fine elastic and connective fibres and fat cells, this wedge-shaped body occupies the space between the two lateral cartilages, the extremity of the perforans tendon, and the horny frog. it offers for consideration an antero-superior and an infero-posterior face, a base, an apex, and two borders. the antero-superior face is in contact with the terminal expansion of the perforans tendon. the infero-posterior face is covered by the keratogenous membrane, and follows closely the shape of the horny frog, on whose inner surface it is moulded. it presents, therefore, at its centre a single conical prolongation, the _pyramidal body_, which is continued behind, as is the horny frog, in the shape of two lateral ridges divided by a median cleft. the _base_ of the cushion lies behind, and consists of two lateral masses, _the bulbs of the plantar cushion_. in front these are continuous with the ridges of the pyramidal body, while behind they become confounded with the lateral cartilages and the coronary cushion. the _apex_ is fixed into the plantar surface of the os pedis, in front of its semilunar ridge. the _borders_, right and left, are wider behind than before, and are in relation with the inner faces of the lateral cartilages. h. the keratogenous membrane. the keratogenous, or horn-producing membrane, is in reality an extension of the dermis of the digit. it covers the extremity of the digit as a sock covers the foot, spreading over the insertion of the extensor pedis, the lower half of the external face of the lateral cartilages, the bulbs of the plantar cushion, the pyramidal body, the anterior portion of the plantar surface of the os pedis, and over the anterior face of the same bone. in turn, as the human foot with its sock is covered by the boot, this is encased by the hoof, the formation of which we shall study later. to expose the membrane for study the hoof must be removed. this may be done in two ways. by roasting in a fire, and afterwards dragging off the horny structures with a pair of pincers, a knife having first been passed round the superior edge of the horny box. or by maceration in water for several days, when the hoof will become loosened by the process of decomposition, and may be easily removed by the hands. the latter method is less likely to injure the sensitive structures, and will expose them with a fresh appearance for observation. for purposes of description the keratogenous membrane is divided into three regions: 1. the coronary cushion. 2. the velvety tissue. 3. the podophyllous tissue, or the sensitive laminæ. 1. the coronary cushion. in the foot stripped of the hoof the coronary cushion is seen as a rounded structure overhanging the sensitive laminæ after the manner of a cornice. it extends from the inner to the outer bulbs of the plantar cushion, and is bounded above by the perioplic ring, and below by the laminæ. when _in situ_ it is accommodated by the _cutigeral groove_, a cavity produced by the bevelling out of the superior portion of the inner face of the wall of the hoof. its superior surface is covered by numerous elongated papillæ, set so closely as to give the appearance of the 'pile' of velvet. this is observed to the best advantage with the foot immersed in water. _the superior border_ of the cushion is bounded by the _perioplic ring_, the cells of which have as their function the secreting of the _periople_, a layer of thin horn to be noted afterwards as covering the external face of the wall. from the perioplic ring the cushion is separated by a narrow and shallow, though well-marked, groove. the inferior border is bounded by the sensitive laminæ. [illustration: fig. 17.--the keratogenous membrane (viewed from the side). (the hoof removed by maceration.) 1. the sensitive laminæ, or podophyllous tissue; 2, the coronary cushion; 3, the perioplic ring; 4, portion of plantar cushion; 5, groove separating perioplic ring from coronary cushion; 6. the sensitive sole.] the upper portions of the laminæ, those in contact with the cushion, are pale in contrast with the portions immediately below, and thus there is given the appearance of a white zone adjoining the inferior border of the cushion. widest at its centre, the cushion narrows towards its extremities, which, arriving at the bulbs of the plantar cushion, bend downwards into the lateral lacunæ of the pyramidal body, where they merge into the velvety tissue of the sole and frog. the papillæ of the coronary cushion secrete the horn tubules forming the wall, and the papillæ of the perioplic ring secrete the varnish-like veneer of thin horn covering the outside surface of the hoof. [illustration: fig. 18.--the keratogenous membrane (viewed from below). (the hoof removed by maceration.) 1, the sensitive sole; 2, the sensitive frog[a]--(a) its median lacuna, (6) its lateral lacuna; 3. v-shaped depression accommodating the toe-stay; 4, the sensitive laminæ which interleave with the horny laminæ of the bar.] [footnote a: the sensitive frog thinly invests the plantar cushion or fibre-fatty frog, the outline of which is here indicated.] 2. the velvety tissue.--this is the portion of the keratogenous membrane covering the plantar surface of the os pedis and the plantar cushion. to the irregularities of the latter body--its bulbs, pyramidal body, and its lacunæ--it is closely adapted. its surface may, therefore, be divided into _(a) the sensitive frog_, and _(b) the sensitive sole_. _(a) the sensitive frog_ is that part of the velvety tissue moulded on the lower surface of the plantar cushion. the shape of the plantar cushion has already been described as identical with that of the horny frog. it only remains to state that, like the coronary cushion, the surface of the sensitive frog is closely studded with papillæ. the cells clothing the papillæ are instrumental in forming the horny frog. _(b) the sensitive sole_.--as its name indicates, this is the portion of the keratogenous membrane that covers the plantar surface of the os pedis. it also is clothed with papillæ, which again give rise to the formation of that part of the horny box to which they are adapted--namely, the sole. 3. the podophyllous tissue, or sensitive laminæ.--this portion of the keratogenous membrane is spread over the anterior face and sides of the os pedis, limited above by the coronary cushion, and below by the inferior edge of the bone. it presents the appearance of fine longitudinal streaks, which, when closely examined with a needle, are found to consist of numerous fine leaves. these extend downwards from the lower border of the coronary cushion to the inferior margin of the os pedis. at this point each terminates in several large villous prolongations, which extend into the horny tubes at the circumference of the sole. at the point of the toe this membrane sometimes shows a v-shaped depression, into which fits a inverted v-shaped prominence on the inner surface of the wall at this point. the sensitive laminæ increase in width from above to below. their free margin is finely denticulated, while their sides are traversed from top to bottom by several folds (about sixty), which, examined microscopically, are seen to consist of secondary leaves, or _laminellæ_. examined on the foot, deprived of its horny covering, the sensitive laminæ are, the majority of them, in close contact with each other. in the normal state this is not so. the interstices between the leaves are then occupied by the horny leaves, to be afterwards described as existing on the inner surface of the wall. reaching and rounding the heels, the sensitive laminæ extend forward for a short distance, where they interleave with the horny laminæ of the bars. much discussion has centred round the point as to whether or no the cells of the sensitive laminæ take any share in the formation of the horn of the wall. this will be alluded to in a future chapter. i. the hoof. removed from the foot by maceration a well-shaped hoof is cylindro-conical in form, and appears to the ordinary observer to consist of a box or case cast in one single piece of horn. prolonged maceration, however, will show that the apparently single piece is divisible into three. these are known as (1) the wall, (2) the sole, and (3) the frog. in addition to these, we have also an appendage or circular continuation of the frog named (4) the periople, or coronary frog band. these various divisions we will study separately. 1. the wall is that portion of the hoof seen in front and laterally when the horse's foot is on the ground. posteriorly, instead of being continued round the heels to complete the circle, its extremities become suddenly inflected downwards, forwards, and inwards. these inflections can only be seen with the foot lifted from the floor, and form the so-called _bars_. it will be noticed, too, with the foot lifted, that the wall projects beyond the level of the other structures of the plantar surface, taking upon itself the bearing of the greatest part of the animal's weight. the horn of the wall, viewed immediately from the front, is known as the _toe_, which again is distinguished as _outside toe_ or _inside toe_, according as the horn to its inner or outer aspect is indicated. the remainder of the external face of the wall, that running back to the heels, is designated the _quarters_. in the middle region of the toe, the wall following the angle of the bones is greatly oblique. this obliquity decreases as the quarters are reached, until on reaching the heels the wall is nearly upright. [illustration: fig. 19.--the wall of the hoof. 1, the toe; 2, inner toe; 3, outside toe; 4, the quarter; 5, entigeral groove; 6, horny laminæ.] for observation the wall offers two faces, two borders, and two extremities. _the external face_ is convex from side to side, but straight from the upper to the lower border. examined closely, it is seen to be made up of closely-arranged parallel fibres running in a straight line from the upper to the lower border, and giving the surface of the foot a finely striated appearance. in addition to these lines, which are really the horn tubules, the external face is marked by a series of rings which run horizontally from heel to heel. these are due to varying influences of food, climate, and slight or severe disease. this will be noted again in a later page. in a young and healthy horse the whole of the external face of the wall is smooth and shining. this appearance is due to a thin layer of horn, secreted independently of the wall proper, termed the periople. [illustration: fig. 20.--internal features of the wall, frog, and sole (mesian section of hoof). 1, horny laminæ covering internal face of wall; 2, superior border of wall; 3, junction of wall with horny sole; 4, the cutigeral groove; 5, the horny sole; 6, the horny frog (that portion of it known as the 'frog-stay'); 7, inverted v-shaped ridge on wall and sole (known as the 'toe-stay'); 8, anterior face of wall; 9, inferior border of wall.] _the internal face_ of the wall, that adapted to the sensitive laminæ, is closely covered over its entire surface with white parallel leaves _(keraphyllæ_, or horn leaves, to distinguish them from the _podophyllæ_, or sensitive leaves). these keraphyllæ dovetail intimately with the sensitive laminæ, covering the os pedis. running along the superior portion of the inner face is the _cutigeral groove_. this cavity has been mentioned before as accommodating the coronary cushion, whose shape and general contour it closely follows, being widest and deepest in front, and gradually decreasing as it proceeds backwards. it is hollowed out at the expense of the wall, and shows on its surface numberless minute openings which receive the papillæ of the coronary cushion. at the bottom of the internal face, at the point where the toe joins the sole, will be noted the before-mentioned inverted v-shaped prominence. its position will be clearly understood when we say that it gives the appearance of having been forced there by the pressure of the toe-clip of the shoe. this will be noted again when dealing with the sole. _the inferior border_ of the wall offers little to note. it is that portion in contact with the ground, and subject to wear. a point of interest is its union with the sole. this will be noticed in a foot which has just been pared as a narrow white or faint yellow line on the inner or concave face of the wall at its lower portion. it marks the point where the horny leaves of the wall terminate and become locked with corresponding leaves of the circumference of the sole. _the superior border_ follows closely the line marked by the perioplic ring and the groove separating the latter from the coronary cushion. _the extremities_ of the wall are formed by the abruptly reflected portions of the wall at the heels. termed by some the 'inflexural nodes,' they are better known to us as the '_points of the heels_.' 2. the sole.--the sole is a thick plate of horn which, in conjunction with the bars and the frog, forms the floor of the foot. in shape it is irregularly crescentic, its posterior portion, that between the horns of the crescent, being deeply indented in a v-shaped manner to receive the frog. its upper surface is convex, its lower concave. it may be recognised as possessing two faces and two borders. _the superior or internal face_ is adapted to the sole of the os pedis. its highest point, therefore, is at the point of its v-shaped indentation. from this point it slopes in every direction downwards and outwards until near the circumference. here it curves up to form a kind of a groove in which is lodged the inferior edge of the os pedis. in the centre of its anterior portion--that is to say, at the toe--will be seen a small inverted v-shaped ridge, which is a direct continuation of the same shaped prominence before mentioned on the internal face of the wall. this fleming has termed the toe-stay, from a notion that it serves to maintain the position of the os pedis. the whole of the superior face of the sole is covered with numerous fine punctures which receive the papillæ of the sensitive sole. _the inferior face_ is more or less concave according to circumstances, its deepest part being at the point of the frog. sloping from this point to its circumference, it becomes suddenly flat just before joining the wall. its horn in appearance is flaky. [illustration: fig. 21.--inferior aspect of hoof. _a_ the inferior face of horny sole; _b_, inferior border of the wall; _c_, body or cushion of the frog; _d_, median lacuna of the frog; _e_, lateral lacuna of the frog; _f_, the bar; _g_, the quarter; _h_, the point of the frog; _i_ the heel.] _the external border_ or circumference is intimately dovetailed with the horny laminæ of the wall. at its circumference the sole, if unpared, is ordinarily as thick as the wall. this thickness is maintained for a short distance towards its centre, after which it becomes gradually more thin. _the internal border_ has the shape of an elongated v with the apex pointing forwards. it is much thinner than the external border, and, like it, is dovetailed into the horny laminæ of the inflections of the wall--namely, the bars. in front of the termination of the bars it is dovetailed into the sides and point of the frog. where unworn by contact with the ground, the horn of the sole is shed by a process of exfoliation. 3. the frog.--triangular or pyramidal in shape, the frog bears a close resemblance to the form of the plantar cushion, upon the lower surface of which body it is moulded. it offers for consideration two faces, two sides, a base, and a point or summit. [illustration: fig. 22.--hoof with the sensitive structures removed. 1, superior face of horny frog; 2, the frog-stay; 3, the lateral ridges of the frog's superior surface; 4, the horny laminæ at the inflections of the wall.] _the superior face_ is an exact cast of the lower surface of the plantar cushion. it shows in the centre, therefore, a triangular depression, with the base of the triangle directed backwards. posteriorly, the depression is continued as two lateral channels divided by a median ridge. the median ridge widens out as it passes backwards, forming the larger part of the posterior portion of the frog. this median ridge fits into the cleft of the plantar cushion. it serves to prevent displacement of the sensitive from the horny frog, and has been rather aptly termed the '_frog-stay_.' _the inferior surface_ is an exact reverse of the superior. the triangular depression of the superior surface is represented in the inferior surface by a triangular projection, and the ridge-like frog-stay of the upper surface is represented below by a median cleft, the _median lacuna_ of the frog. the triangular projection in front of the median lacuna is the body or cushion of the frog. it is continued backwards as two ridge-like branches, which, at the points of the heels, form acute angles with the bars. on the outer side of each lateral ridge is a fissure. these are known as the lateral lacunæ. _the sides_ of the frog are flat and slightly oblique. they are closely united to the bars and to the triangular indentation in the posterior border of the sole. _the base_ of the frog is formed by the extremities of its branches, which, becoming wider and more convex as they pass backwards, form two rounded, flexible, and elastic masses separated from each other by the median lacuna. these constitute the 'glomes' of the frog. they are continuous with the periople. _the point of the frog_ is situated, wedge-like, within the triangular notch in the posterior border of the sole. 4. the periople, or coronary frog band.--this is a continuation of the substance of the frog around the extreme upper surface of the hoof. it is widest at the heels over the bulbs or glomes of the frog, and gradually narrows as it reaches the front of the hoof. it is, in reality, a thin pellicle of semi-transparent horn secreted by the cells of the perioplic ring. when left untouched by the farrier's rasp it serves the purpose, by acting as a natural varnish, of protecting the horn of the wall from the effects of undue heat or moisture. chapter iii general physiological and anatomical observations the matter embraced by the heading of this chapter will offer for discussion many subjects of great interest to the veterinary surgeon. around some of them debate has for many years waxed more than keen. of the points in dispute, some of them may be regarded as satisfactorily settled, while others offer still further room for investigation. in this volume we can only hope to deal with them in brief, and must select such as appear to have the greatest bearing on the veterinarian's everyday practice. always prolific of heated discussion has been one question: 'are the horny laminæ secreted by the sensitive?' to answer this satisfactorily, it will be best to give a short account of the mode of production of the hoof in general. a. development of the hoof. starting with the statement that it is epidermal in origin, we will first consider the structure of the skin, and follow that with a brief description of the structure and mode of growth of the human nail, a short study of which will greatly assist us when we come to investigate the manner of growth of the horse's hoof. the skin is composed of two portions, the epidermis and the corium. the epidermis is a stratified epithelium. the superficial layers of the cells composing it are hard and horny, while the deeper layers are soft and protoplasmic. these latter form the so-called _retae mucosum_ of malpighi. [illustration: fig. 23.--vertical section of epidermis (human). (after ranvier) _a_, the horny layer of the epidermis; _b_, the rete mucosum; _a_, the columnar pigment-containing cells of the rete; _b_, the polyhedral cells; _c_, the stratum granulosum; _d_, the stratum lucidum; _e_, swollen horny cells; _f_ the stratum squamosum.] commencing from below and proceeding upwards, we find that the lowermost cells of the rete mucosum, those that are set immediately on the corium, are columnar in shape. in animals that have a coloured skin these cells contain pigment granules. directly superposed to these we find cells which in shape are polyhedral. above them, and forming the most superficial layer of the rete mucosum, is a series of flattened, granular-looking cells known as the _stratum granulosum_. immediately above the stratum granulosum the horny portion of the epidermis commences. in the human skin this is formed of three distinct layers. undermost a layer of clear compressed cells, the _stratum lucidum_. next above it a layer of swollen cells, the nuclei of which are indistinguishable. finally, a surface layer of thin, horny scales, the _stratum squamosum_, which become detached and thrown off in the form of scurf or dandruff. in the skin of the horse, except where it is thickest, these layers are not clearly defined. it is the malpighian layer of the epidermis that is most active in cell division. as they are formed the new cells push upwards those already there, and the latter in their progress to the surface undergo a chemical change in which their protoplasm is converted into horny material. this change, as we have already indicated, takes place above the stratum granulosum. in addition to its constant formation of cells to replace those cast off from the surface, the active proliferation of the elements of the malpighian layer is responsible for the development of the various appendages of the skin, the hairs with their sebaceous glands, the sweat glands, horny growths and the hoof, and, in the human subject, the nail. these occur as thickenings and down-growths of the epithelium into the corium. the epidermis is devoid of bloodvessels, but is provided with fine nerve fibrils which ramify between the cells of the rete mucosum. the corium is composed of dense connective tissue, the superficial layer of which bears minute papillæ. these project into the epidermis, which is moulded on them. for the most part the papillæ contain looped capillary vessels, rendering the superficial layer of the corium extremely vascular. why this must be a moment's reflection will show. the epidermis, as we have already said, is devoid of bloodvessels. it therefore depends entirely for its nourishment upon the indirect supply it receives from the vessels of the corium. the need for extreme vascularity of the corium is further explained when we call to mind the constant proliferation and casting off of the cells of the epidermis, the growth of the hairs, the production of the horn of the hoof, and the work performed by the numerous sweat and other glands. others of the papillæ contain nerves, ending here in tactile corpuscles, or continuing, as we have mentioned before, to ramify as fine fibrils in the rete mucosum of the epidermis. the hairs are growths of the epidermis extending downwards into the deeper part of the corium. each is developed in a small pit, the _hair follicle_, from the bottom of which it grows, the part lying within the follicle being known as the _root_. it is important to note their structure, as it will be seen later that they bear an extremely close relation to the horn of the hoof. under a high power of the microscope, and in optical section, the central portion of a hair is tube-like. in some cases the cavity of the tube is occupied by a dark looking substance formed of angular cells, and known as the _medulla_. the walls of the tube, or the main substance of the hair, is made up of a pigmented, _horny, fibrous material_. this fibrous structure is covered by a delicate layer of finely imbricated scales, and is termed the _hair cuticle_. the root of the hair, that portion within the follicle, has exactly the same formation save at its extreme end. here it becomes enlarged into a knob-like formation composed of soft, growing cells, which knob-like formation fits over a vascular papilla projecting up in the bottom of the follicle. we have already stated that the hairs are down-growths of the epidermis. it follows, therefore, that the hair follicles, really depressions or cul-de-sacs of the skin itself, are lined by epithelial cells and connective tissue. so closely does the epidermal portion of the follicle invest the hair root that it is often dragged out with it, and is known as the _root sheath_. this is made up of an outer layer of columnar cells (_the outer root sheath_) corresponding to the malpighian layer of the epidermis, and of an inner horny layer, next to the hair, corresponding to the more superficial layer of the epidermis, and known as the _inner root sheath_. the hair grows from the bottom of the follicle by a multiplication of the cells covering the papilla upon which its root is moulded. when a hair is cast off a new one is produced from the cells covering the papilla, or, in case of the death or degeneration of the original papilla, the new hair is produced from a second papilla formed in place of the first at the bottom of the follicle. [illustration: fig. 24.--section of skin with hair follicle and hair. _a_, the hair follicle; _b_, the hair root; _c_, the medulla; _d_, the hair cuticle; _e_, the outer root sheath; _f_, the inner root sheath; _g_, the papilla from which the hair is growing; _h_, a sebaceous gland; _i_, a sudoriferous gland.] the sebaceous glands are small saccular glands with their ducts opening into the mouths of the hair follicles. they furnish a natural lubricant to the hairs and the skin. the sudoriferous or sweat glands are composed of coiled tubes which lie in the deeper portion of the skin, and send up a corkscrew-like duct to open on the surface of the epidermis. they are numerous over the whole of the body. [illustration: fig. 25.--longitudinal section through nail and nail-bed of a human foetal finger.[a] _a_, the nail; _b_, the rete mucosum; _c_, the longitudinal ridges of the corium.] [footnote a: seeing that the section is a longitudinal one, it would appear from the way the ridges cut that they are running transversely beneath the nail. their extreme delicacy, however, prevents a single one showing itself along the length of the section, and their constant accidental cutting makes them _appear_ to run transversely (h.c.r.).] the human nails are thickenings of the lowermost layer of the horny portion of the epidermis, the stratum lucidum. they are developed over a modified portion of the corium known as the nail-bed. the horny substance of the nail is composed of clear horny cells, and rests immediately upon a malpighian layer similar to that found in the epidermis generally. instead of the papillæ present elsewhere in the skin, the corium of the nail-bed is marked by longitudinal ridges, a similar, though less distinct, arrangement to that found in the laminæ of the horse's foot. having thus paved the way, we are now in a better position to discuss our original question (are the horny laminæ secreted by the sensitive?), and better able to appreciate the work that has been done towards the elucidation of the problem. a most valuable contribution to this study is an article published in 1896 by professor mettam.[a] here the question is dealt with in a manner that must effectually silence all other views save such as are based upon similar methods of investigation--namely, histological examination of sections of equine hoofs in various stages of foetal development. [footnote a: the _veterinarian_, vol. lxix., p.1.] professor mettam commences by drawing attention to the error that has been made in this connection by studying the soft structures of the foot separated by ordinary putrefactive changes from the horny covering. "in this way," the writer points out, "a wholly erroneous idea has crept in as to the relation of the one to the other, and the two parts have been treated as two anatomical items, when, indeed, they are portions of one and the same thing. as an illustration, and one very much to the point at issue, the soft structures of the foot are to the horny covering what the corium of the skin and the rete malpighii are to the superficial portions of the epidermis. indeed, the point where solution of continuity occurs in macerating is along the line of the soft protoplasmic cells of the rete." in the foregoing description of the skin we have seen that the corium is not a _plane_ surface, but that it is studded by numerous papillary projections, and that these projections, with the depressions between them, are covered by the cells of the epidermis. the corium of the horse's foot, however, although possessed of papillæ in certain positions (as, for example, the papillæ of the coronary cushion, and those of the sensitive frog and sole), has also most pronounced ridges (laminæ) which run down the whole depth of the os pedis. each lamina again carries ridges (laminellæ) on its lateral aspects, giving a section of a lamina the appearance of being studded with papillæ. we have already pointed out the ridge-like formation of the human nail-bed, and noted that, with the exception that the secondary ridges are not so pronounced, it is an exact prototype of the laminal formation of the corium of the horse's foot. the distribution of the laminæ over the foot we have discussed in the chapter devoted to the grosser anatomy. in a macerated foot the sensitive laminæ of the corium interdigitate with the horny laminæ of the hoof; that is to say, there is no union between the two, for the simple reason that it has been destroyed; they simply interlock like the _unglued_ junction of a finely dovetailed piece of joinery. but no further, however, than the irregularities of the underneath surface of the epidermis of the skin can be said to interlock with the papillæ of the corium does interlocking of the horny and sensitive laminæ occur. it is only apparent. the horny laminæ are simply beautifully regular epidermal ingrowths cutting up the corium into minute leaf-like projections. in a macerated specimen, then, the exposed sensitive structures of the foot exhibit the corium as (1) the _coronary cushion_, fitting into the cutigeral groove; (2) the _sensitive laminæ_, clothing the outer surface of the terminal phalanx, and extending to the bars; (3) the _plantar cushion_, or sensitive frog; and (4) the _sensitive sole_. the main portion of the wall is developed from the numerous papillæ covering the corium of the coronary cushion. we have in this way numberless down-growing tubes of horn. professor mettam describes their formation in a singularly happy fashion: "let the human fingers represent the coronary papillæ, the tips of the fingers the summits of the papillæ, and the folds of skin passing from finger to finger in the metacarpo-phalangeal region the depressions between the papillæ. imagine that all have a continuous covering of a proliferating epithelium. then we shall have a more or less continuous column of cells growing from the tip of the finger or papilla (a hollow tube of cells gradually moving from off the surface of the finger or papilla like a cast), and similar casts are passing from off all the fingers or papillæ." from this description it will be noticed that each down-growing tube of horn bears a striking resemblance to the growth of a hair, described on p. 47. in fact, the horn tube may be regarded as what it really is, a modified hair. we next continue professor mettam's illustration, and note how the modified hairs or horn tubes become as it were matted together to form the hoof wall. the cells lining the depressions are also proliferating, and their progeny serve to cement together the hollow casts of the papillæ, thus giving the _inter_-tubular substance. we have thus produced hollow tubes, united together by cells, all arising from the rete malpighii of the coronary corium. section of the lower part of the horn tubes shows them to contain a cellular debris. thus, in all, in the horn of the wall we find a tubular, an intertubular, and intratubular substance. in fact, hairs matted together by intertubular material, and only differing from ordinary hairs in their development in that they arise, not from papillæ sunk in the corium, but from papillæ projecting from its surface. although this disposes of the wall proper, there still confronts us the question of the development of the horny laminæ. to accurately determine this point it is absolutely essential to examine, histologically, the feet from embryos. in the foot of any young ungulate in the early stages of intra-uterine life horizontal sections will show a covering of epidermis of varying thickness.[a] this may be only two or three cells thick, or may consist of several layers. lowermost we find the cells of the rete malpighii. as some criterion of the activity with which these are acting, it may be noted that with the ordinary stains their nuclei take the dye intensely. the cells of this layer rest upon a basement membrane separating the epidermis from the corium. at this stage _the corium has a perfectly plane surface_. [footnote a: equine foetus, seventy-seven days old.] [illustration: fig. 26.--section of foot of equine foetus, seventy-seven days old. the rete malpighii rests on a plane corium; the rent in the section is along the line of the cells of the rete (mettam).] [illustration: fig. 27.--section from foot of sheep embryo. it shows a pronounced epithelial ingrowth into the corium (mettam).] the next stage will demonstrate the first step in the formation of the sensitive laminæ.[a] the plain surface of the corium has now become broken up, and what is noticed is that the broken-up appearance is due to the epithelial cells irrupting and advancing _en échelon_ into its connective tissue. each point of the ingrowing lines of the _échelon_ has usually one cell further advanced into the corium than its neighbours, and may be termed the _apical cell_. the fine basement membrane separating epithelium from corium is still clearly evident. this epidermal irruption of the corium takes place at definite points right round the foot. it is extremely probable, however, that it commences first at the toe and spreads laterally. [footnote a: sheep embryo, exact age unknown.] as yet, these cellular ingrowths (which are destined to be the _horny_ laminæ, and cut up the corium into _sensitive_ laminæ) are free from irregularities or secondary laminæ. before these are to be observed other changes in connection with the ingrowths are to be noticed. [illustration: fig. 28.--section from calf embryo. the epithelial ingrowths hang down from the epidermis into the corium like the teeth of a comb (mettam).] the first is merely that of elongation of the epithelial processes into the connective tissue, until the rete malpighii gives one the impression that it has hanging to its underneath surface and into the corium a number of thorn-like processes. these extend all round the front of the foot, and even in great part behind. accompanying this elongation of the processes is a condensation of the epithelial cells immediately above the rete malpighii, with a partial or total loss of their nuclei. this is the first appearance of true horn, and its commencement is almost coincident with the first stages of ossification of the os pedis. [illustration: fig. 29.--section of an epithelial ingrowth from an equine foetus. it shows commencing secondary laminar ridges. in the centre are epithelial cells which are undergoing change into horny elements to form the horn core, or 'horny laminæ' (mettam).] with the appearance of horn comes difficulty of sectioning. the last specimen that professor mettam was able to satisfactorily cut upon the microtome was from a foetus between three and four months old. in this the secondary laminar ridges were clearly indicated, and the active layer of the rete malpighii could be traced without a break from one ingrowing epithelial process to the next, and around this, following all the irregularities of its outline, and covering the branches of the nascent laminæ. the laminæ mostly show this branching as if a number of different growing points had arisen, each to take on a function similar to the epithelial process as it at first appeared. in the centre of the processes a few nuclei may be observed, but they are scarce, and stain only faintly; they have arisen from the cells of the rete malpighii which have grown into the corium. in fact, the active cells are passing their daughters into the middle of the process, and these pass through similar stages as those derived from the ensheathing epidermis. in other words, the daughter cells of the constituents of the rete malpighii which have grown into the corium pass through a degeneration precisely similar to that undergone by cells shed at desquamation, or those which eventually give rise by their agglutination to a hair. this is the real origin of the horny laminæ, and the thickness of these is increased merely by an increase in the area covered by the cells of the rete malpighii--i.e., by the development of secondary laminar ridges. if a section from a foal at term be examined, the processes will be found far advanced into the corium, and, occupying the axis of each process, will be seen a horny plate, continuous with the horn of the wall. no line of demarcation can be observed between the horn so formed and the intertubular material of the wall. they merge into and blend with each other, with no indication of their different origins. the cells that have invaded the corium have thus _not lost their horn-forming function_. there has merely been an increase in the area for horn-producing cells. the horny processes are continuous with the hoof proper at the point where the epithelial ingrowth first commenced to invade the corium, and fuses here with the horn derived from the cells of the rete malpighii which have _not_ grown inwards, and which are found between the processes in the intact foot. from this it is clear that some considerable portion of the horn of the wall is derived from the cells of the rete malpighii covering the corium of the foot. it becomes even more clear when we remember the prompt appearance of horn in cases where a portion, or the whole, of the wall has been removed by operation or by accident (see reported cases in chapter vii.). the activity of the cells of the rete malpighii of the corium covering the remainder of the foot will be quite as necessary as the activity of the cells of the coronary papillæ which form the horn tubes themselves. 'for,' in professor mettam's own words, 'i am inclined to believe that much of the "white line" which is found uniting the wall of the hoof to the sole has been derived from the horn formed from the rete of the foot corium. this origin will explain the absence of pigment from this thin uniting "line," as it does from the horn lining the interior of the wall. the cells of the rete are free of colouring matter.' [illustration: fig. 30.--section through hoof and soft tissues of a foal at term. the horn of the wall is shown, and the horn-core ('horny laminæ') of the epithelial ingrowth. the latter has advanced far into the corium, and is now provided with abundant secondary laminar ridges (mettam).] from the matter here given us it is easy to understand how, in a macerated foot, the appearance is given of interlocking of the sensitive and horny laminæ. we see that the horny laminæ are ingrowths of the rete malpighii, ploughing into and excavating the corium into the shape of leaves--the sensitive laminæ. putrefactive changes simply break into two separate portions what originally was one whole, by destroying the cells along its weakest part. this part is the line of soft protoplasmic cells of the rete malpighii. thus the more resistant parts (the horn on the one hand, and the corium covering the foot on the other) are easily torn asunder. as a result of the evidence we have quoted, we are able to answer our original question in the affirmative. seeing that the horny and the sensitive laminæ are both portions of the same thing--namely, a modified skin, in which the epidermis is represented by the horny laminæ, and the corium by the sensitive--it is clear to see that the cells covering the inspreading horny laminæ are dependent for their growth and reproduction upon the cells with which they are in immediate contact--namely, those of the sensitive laminæ--and that therefore the sensitive laminæ are responsible for the growth of the horny. b. chemical properties and histology of horn. horn is a solid, tenacious, fibrous material, and its density in the hoof varies in different situations. it is softened by alkalies, such as caustic potash or soda and ammonia, the parts first attacked being the commissures, then the frog, and afterwards the sole and wall. strong acids, such as sulphuric acid and nitric acid, also dissolve it. the chemical composition of the hoof shows it to be a modification of albumin, its analysis yielding water, a large percentage of animal matter, and materials soluble and insoluble in water. the proportions of these, as existing in the various parts of the hoof, have been given by professor clement as follows: wall. sole. frog. water 16.12 36.0 42.0 fatty matter 0.95 0.25 0.50 matters soluble in water 1.04 1.50 1.50 insoluble salts 0.26 0.25 0.22 animal matter 81.63 62.0 55.78 horn appears to be identical with epidermis, hair, wool, feathers, and whalebone, in yielding 'keratin,' a substance intermediate between albumin and gelatine, and containing from 60 to 80 per cent. of sulphur. that horn is combustible everyone who has watched the fitting of a hot shoe knows. that it is a bad conductor of heat, the absence of bad after-effects on the foot testifies. [illustration: fig. 31.--perpendicular section of horn of wall.] in a previous page we have described the manner of growth of the horn tubules, and noted the direction they took in the wall; also, we have noticed the existence between them of an intertubular horn or cement. those who wish to give this subject further study will find an excellent series of articles by fleming in the _veterinarian_ for 1871. we shall content ourselves here with introducing one or two diagrams and photo-micrographs, and dealing with the histology very briefly. under the microscope the longitudinal striation of the wall is found to be due to the direction taken by the horn tubules. fig. 31 is a magnified perpendicular section of the wall. in it the parallel dark striæ are the horn tubules in longitudinal section. the lighter striæ represent the intertubular material. fig. 32 gives us the wall in horizontal section. to the left of this picture we find the horn tubules cut across, and standing out as so many concentrically ringed circles. in the centre of the figure are seen the horny laminæ, with their laminellæ, and the sensitive laminæ. the right portion of the figure pictures the corium. [illustration: fig. 32.--horizontal section of horn of wall.] fig. 33 is, again, a horizontal section, cut this time at the junction of the wall with the sole. to the left are seen, again, the horn tubules of the wall, and to the centre the horny laminæ. in this position, however, the structures interdigitating with the horny laminæ are not sensitive, but are themselves horny. as the diagram shows, they contain regularly arranged horn tubules cut across obliquely. it is this horn which forms the 'white line.' to the extreme right of the figure are seen the horn tubules of the sole. there remains now but to notice the arrangement of the horn tubules in the frog. the peculiar, indiarubber-like toughness of this organ is well known. histological examination gives a reason for this. [illustration: fig. 33.--horizontal section of horn through the junction of the wall with the sole. _a_, horn tubule of the wall; _b_, horn tubule of the sole; _c, d_, horny laminæ.] [illustration: fig. 34.--section of frog through corium and horn. the long finger-like projections of corium into epidermis are sections of the long papillæ from which the horn-tubes of the sole grow. in the stainable portion of the epidermis are to be clearly seen light and dark streaks pointing out the alternate strata-like arrangement of cells mentioned in the text (mettam).] the horn tubules of the frog are sinuous in their course. this is accounted for by the fact that in the horn of the frog there is a large amount of intertubular material, this having the effect of frequently turning the horn tubules from the straight. in addition to this, the intertubular material has a peculiar arrangement of the cells composing it. these are laid down in alternating striæ (1) of cells with their long axes longitudinal, and (2) of cells with their long axes horizontal. this is seen in fig. 34, between the long papillæ of the corium, where the lines of longitudinally arranged cells in horizontal section stand out darker than the adjoining strata in which their arrangement is horizontal. the tortuous direction of the horn tubules, and the almost interlocking nature of the alternating strata of the intertubular material, together combine to give the frog its characteristic toughness and resiliency. c. expansion and contraction of the hoof. among other questions productive of heated argument come those relating to expansion of the horse's hoof. in the past many observers have strenuously insisted on the fact that expansion and contraction regularly occur during progression. opposed to them have been others equally firm in the belief that neither took place. quite within recent times this question also has been settled once and for all by the experiments of a. lungwitz, of dresden. his conclusions were published in an article entitled 'changes in form of the hoof under the action of the body-weight.'[a] [footnote a: _journal of comparative pathology and therapeutics_, vol. iv., p. 191. the whole of the matter in this article, from which we have borrowed figs. 35 and 36, is too long for reproduction here. it forms, however, most instructive reading, and its careful perusal will well repay everyone interested in this most important question (h.c.r.).] in connection with this it is interesting to note how, all unconsciously, two separate observers were simultaneously arriving by almost identical means at an equally satisfactory answer to the question. prior to the publication of lungwitz's article on the subject, colonel f. smith, a.v.d., had arrived at similar conclusions by working on the same methods. [illustration: fig. 35. i. electric bell with dry element. a, under part, with box, for the dry element; 6, roller for winding up the conducting-wires; c, dry element, with screw-clamp for attachment of the conducting-wires; c', conducting-wire leading to the screw-clamp, with contact-spring in c', fig. 2, or to the wall in fig. 3; d, upper part, with bell; d', conducting-wire to the shoe d' in figs. 2 and 3; e, strap for slinging the apparatus around the body of the assistant or rider; f, connecting-wire between bell and dry element.] [illustration: fig. 35. ii. hoof shod with shoe provided with toe-piece and calkins; wall of the hoof covered with tinfoil. a, heel angle, with b, the contact-screws; c, screw-clamp, with contact-spring (isolated from the shoe); c' conducting-wire from the same; d, screw-clamp, with conducting-wire (d') screwed into the edge of the shoe; e, nails isolated by cutting a small window in the tinfoil.] [illustration: fig. 35. iii. hoof shod with plain shoe; horny wall covered with tinfoil. a, toe and heel angle, with b, the contact-screws; c, conducting-wire passing from the tinfoil on the wall; d, conducting-wire passing from the shoe; c', d', ends of the conducting-wires, which must be imagined connected with the ends c', d', passing from the apparatus.] it is unnecessary for our purpose here to minutely describe the exact _modus operandi_ of these two experimenters. briefly, the method of inquiry adopted in each case was the 'push and contact principle' of the ordinary electric bell, and the close attention which was paid to detail will be sufficiently gathered from figs. 35 and 36. [illustration: fig. 36. i. left fore-foot shod and mounted to recognise the sinking of the sole. _a_, iron plate covering the inner half of the horny sole; _b_, openings in the same, with screw-holes for the reception of the contact-screw _c_ (the part of the sole under the plate is covered with tinfoil, which at _d_ passes out under the outer branch of the shoe, and becomes connected with the tinfoil of the wall; in order to give the freshly applied tinfoil a better hold, copying-tacks are at _e_ passed through it into the horn, and one is similarly used to protect the tinfoil at the place where the contact-screw touches the latter); _f_, holes with screw thread for the fastening of the angle required to measure the movement of the wall, and also for the fastening of the conducting-wire, _g; h_, conducting-wire passing from the tinfoil; _i_, isolated nails.] [illustration: fig. 36. ii. bar-shoe with openings. _a_, near the inner margin and in the longitudinal bar; _b_, for the reception of the contact-screw _c; d_, openings for fastening the angle and the conducting-wires.] after numerous experiments with the depicted contact-screws, moved to the various positions indicated in the drawings, the following conclusions were arrived at: 1. behaviour of the coronary edge.--during uniform weighting of all four hoofs the coronary edge shows a tendency to contraction in the anterior and lateral regions of the hoof, and a tendency to expansion posteriorly. with heavy weighting of the hoof, which is shown by a backward inclination of the fetlock, contraction in the anterior and lateral regions is slight, but the expansion behind, in the region of the heels, is distinct, commencing gradually in front, becoming stronger, and diminishing again posteriorly. the coronary edge of the heels becomes slightly bulged outwards. the bulbs of the heels swell up and incline a little backwards and downwards. when the fetlock is raised the expansion of the coronary edge of the heels disappears from behind forwards, passing forwards like a fluid wave. in the lateral and anterior regions of the coronary edge the contraction disappears; and when the weight is thrown off the foot it passes into a gentle expansion of the coronary edge of the toe. during the opposite movement of the fetlock, that of sinking backwards, this change of form is executed in the converse manner. in short, the coronary edge resembles a closed elastic ring, which yields to pressure, even the most gentle, of the body-weight, in such a way that a bulging out of any one part is manifested by an inward movement of another part. in fig. 37, _b_, the dotted line represents the changes of form in comparatively well-formed and sound hoofs at the moment of strongest over-extension[a] of the fetlock-joint. [footnote a: the term 'over-extension,' as employed by lungwitz, is intended to indicate that position assumed by the fetlock-joint when the opposite foot is raised from the ground.] 2. behaviour of the solar edge.--under the action of the body-weight this is somewhat different from that of the coronary edge. anteriorly, and at the sides, as far as the wall forms an acute angle with the ground, the tendency to expansion exists, but the change of form first becomes measurable in the region where the lateral cartilages begin. quite posteriorly the expansion again diminishes. fig. 37, _a_, by the dotted line represents the expansion at the moment of over-extension of the fetlock-joint. this expansion is itself rather less than at the coronary edge, and it shows itself distinctly _only when the weighted hoof is exposed to a counter-pressure on the sole and frog_, no matter whether the counter-pressure is produced naturally or artificially. thus anything tending to the removal of the pressure from below, such as a decayed condition of the frog or excessive paring in the forge, will diminish the extent of expansion of the solar edge. contraction of the solar edge of the heels occurs at the moment of greatest over-extension of the fetlock-joint--that is, in a foot with pressure from below absent. on the face of it, this appears impossible. lungwitz, however, has perfectly demonstrated it; and, when dealing with the functions of the lateral cartilages in a later paragraph, we shall show reason for why it is but a simple and natural result of the foot dynamics. 3. behaviour of the sole.--the horny sole becomes flattened under the action of the body-weight. this is most distinct at the solar branches, and gradually shades off anteriorly and towards the circumference. as might be supposed, width of hoof and thickness of the solar horn exert an influence on the extent of this movement. the sinking of the horny sole is most marked in flat hoofs. d. the functions of the lateral cartilages.[a] [footnote a: extracted from a paper by j.a. gilruth, m.r.c.v.s., in the _veterinary record_, vol. v., p. 358.] we have just referred to contraction of the heels as taking the place of a normal expansion in those cases where ground frog-pressure was absent. we shall readily understand this when we bear in mind the anatomy of the parts concerned, especially that of the plantar cushion. this wedge-shaped structure we have already described as occupying the irregular space between the two lateral cartilages, the extremity of the perforans tendon, and the horny frog. now, when weight or pressure is exerted from above on to this organ, and the _frog is in contact with the ground below_, it is clear from the position the cushion occupies that, whatever change of form pressure from above will cause it to take, it must certainly be limited in various directions. [illustration: fig. 37. _a_, the dotted lines in this diagram represent the expansion of the solar edge of the hoof at the moment of over-extension of the fetlock-joint; _b_, the dotted line represents the change in form of the coronary edge under similar circumstances.] because of the shape of the cushion its change of form cannot be forwards (simultaneous pressure from above and below on to this wedge with its apex forwards must tend to give it a backward change of form). because of the pastern being horizontal, and aiding in the downward pressure, its change of form cannot be upwards. and because of the ground it cannot be downwards. it follows, therefore, that the movement must be backwards and outwards, being especially directed outwards because of its shape and the median lacuna in its posterior half--this latter, the lacuna, accommodating as it does the frog-stay, preventing the tendency to backward movement becoming excessive, and directing the change of form to the sides. where the greatest pressure is transmitted, then, is to the inner aspects of the flexible lateral cartilages. the coronary cushion being continuous with the plantar, the backward and outward movements of the latter will tend to pull upon and tighten the former, especially _in front_. this will account for the contraction noted by lungwitz in the _anterior half_ of the coronary edge of the hoof. remove the body-weight, and naturally the elastic nature of the lateral cartilages and the coronary and plantar cushions, with, in a less degree, that of the hoof, cause things to assume their normal position. repeat the weighting of the hoof, in this second case _without frog-pressure_, and we shall see at once that we have done away with one of the greatest factors in determining the outward and backward movements of the plantar cushion--namely, the pressure from below on its wedge-shaped mass. the movement of the plantar cushion will now be _downwards_ as well as backwards; and, seeing that it is attached to the inner aspect of each lateral cartilage, we shall expect these latter, by the downward movement of the plantar cushion, to be drawn _inwards_. this lungwitz has shown to occur. the chief function of the lateral cartilages, therefore, is to _receive the concussion engendered by locomotion_, which concussion is directed backwards and outwards by the pad-like plantar cushion. in addition to this, the lateral cartilages, together with the plantar and coronary cushions, _play the part of a valve to the whole of the veins of the foot_. it is in this way: we have only to refer to the chapter on anatomy to see that the whole of the foot is covered with a tissue of extreme vascularity. thus we find papillæ--the over the coronary cushion; enlarged and modified papillæ sensitive laminæ--covering the anterior face of the os pedis; and numberless papillæ again covering the sole. there can be no doubt that the quantity of fluid brought by the bloodvessels of these papillæ to the foot acts largely as a means of hydraulic protection to the soft structures.[a] in like manner as that delicate organ, the brain, is best protected by being floated upon the cerebro-spinal fluid and bloodvessels (which fluids transmit waves of concussion or pressure _through_ the organ without injury to the delicate cells forming it), so, in like manner, does the extreme vascularity of the foot protect the cells of its softer structures from the effects of pressure and concussion. [footnote a: the _veterinary record_, vol. iii., p. 518.] that this law of hydraulics may operate in the horse's foot to the best advantage, the veins must be provided with valves, and valves of no mean strength. these we know to be absent. it is here that the lateral cartilages and the elastic substances of the coronary and plantar cushions step in to supply the deficiency. at the time when weight is placed upon the foot (with, of course, a tendency to drive the blood upwards in the limb), and, therefore, the time when a valvular apparatus is needed to retain the fluid in the foot, we find the wanting conditions supplied by the pressure outwards of the plantar cushion compressing the large plexuses of veins on each side of the lateral cartilages, to which plexuses, it will be remembered, the bulk of the venous blood from the foot was directed. a more perfect valvular apparatus, automatic and powerful, it would be difficult to imagine. e. growth of the hoof. we will conclude this chapter with a few brief remarks on the growth of the hoof. that the rate of growth is slow is a well-known fact to every veterinarian, and it will serve for all practical purposes when we state that, roughly, the growth of the wall is about 1/4 inch per month. this rate is regular all round the coronet, from which it follows that the time taken for horn to grow from the coronary edge to the inferior margin will vary according as the toe, the quarters, or the heels are under consideration. as might naturally be expected, the rate of growth will depend on various influences. any stimulus to the secreting structures of the coronet, such as a blister, the application of the hot iron, or any other irritant, results in an increased growth. growth is favoured by moisture and by the animal going unshod, as witness the effects of turning out to grass. exercise, a state of good health, stimulating diets--in fact, anything tending to an increased circulation of healthy blood--all lead to increased production of horn. with the effects of bodily disease and of ill-formed legs and feet on the wear of the hoof, and the growth of horn, we shall be concerned in a future chapter. chapter iv method of examining the foot as a general rule, it may be taken that most diseases of the foot are comparatively easy of diagnosis. when, however, the condition is one which commences simply with an initial lameness, the greatest care will have to be exercised by the practitioner. what remarks follow here should rightly be confined to a treatise on lameness. this much, however, we may state: as compared with lameness arising from abnormal conditions in other parts of the limb, that emanating from abnormalities of the foot is easy of detection. with a case of lameness before him, concerning which he is in doubt, the practitioner remembers that a very large percentage may safely be referred to the foot, and, if wise, subjects the foot to a rigorous examination. much may be gathered by first putting the animal through his paces. when at a trot, notice the peculiarity of the 'drop,' whether any alteration in going on hard or soft ground, and watch for any special characteristic in gait. at the same time inquiry should be made as to the history of the case; its duration; whether pain, as evidenced by lameness, is constant or periodic; the effect of exercise on the lameness; and the length of time elapsed since the last shoeing. this failing to reveal adequate cause for the lameness in any higher part of the limb, one is led, by a process of negative deduction, to suspect the foot. if 'pointing' is a symptom, its manner is noticed. the foot is compared with the other for any deviation from the normal. in some cases the two fore or the two hind feet may differ in size. though this may not necessarily indicate disease, it may, nevertheless, be taken into account if the lameness is not easily referable to any other member. measurement with calipers will then be of help, and a pronounced increase in size, especially if marked in one position only, given due consideration. the hand is used upon each foot alternately to look for change of temperature, to detect the presence of growths small enough to escape the eye, and to discover evidence of painful spots along the coronet. at this stage the method of percussion recommends itself, and in many cases no more useful diagnostic agent is to be found than the ordinary hammer. as a preliminary, the foot of the sound limb should be always tapped first. this precaution will serve to bring to light what is frequently met with--the aversion nervous animals sometimes exhibit to this manner of manipulation of the hoof. unless this is done, the ordinary objection to interference is apt to be read as evidence of pain. no aversion to the method being shown, the suspected foot is gently tapped in various places round the wall, a keen look-out being kept for any manifestation of tenderness. this may vary from a slight resentment to each tap, indicated by a sudden lifting and setting down again of the foot, to a complete removal of the foot from the ground, and a characteristic pawing of the air that points out clearly enough the seat of pain. evidence of pain once given, the tapping is persisted in until, in some cases, the exact position of the tender spot is definitely located. failing evidence obtained from percussion, attention should next be given to the shoeing. we may add here that, even when difficulties have to be encountered in doing it, it is always a wise plan to have the shoe removed. the nails should be removed one by one, the course they have taken, their point of emergence on the wall, and the condition of their broken ends all being carefully noted as they are withdrawn. the removed shoe should next be examined as to the coarseness or fineness of its punching and the 'pitch' of its nail-holes, and close attention given to the shape of its bearing surface. from that we may pass to a consideration of the underneath surface of the foot. the drawing-knife should be run lightly over the whole of its surface, the first thing to be noticed being the point of entrance of the nails as compared with the coarseness or fineness of the punching, and the staining or otherwise of the horn immediately around. we may thus be guided towards mischief arising from tight nailing apart from actual prick of the foot. this done, more than usual care should be taken in following up any other small prick or dark spot that may show itself upon the white surface of the cleaned sole. in any case, a suspicious-looking speck should be followed up with the searcher until it is either cut out or is traced to the sensitive structures. while this is done, we should also have noticed the condition of the horn at the seat of corn; should have noticed the shape of the heels, contracted or otherwise; and the appearance of the frog, clean or discharging. a point to be remembered in making this exploratory paring of the foot is the peculiar consistency of the horn of the frog, and its tendency to hide the existence of punctures. in like manner, as a pin pierces a piece of indiarubber, and leaves no clearly visible trace of the hole it has made, so does a nail or other sharp object penetrate the frog, leaving but little to show for the mischief that has been done. after all, even though we may have fully decided the foot is at fault, our case of lameness may remain obscure so far as a cause is concerned. nothing remains, then, but to acknowledge the inability to discover it, to advocate poulticing, or some other expectant palliative measure, and to bring the case up for further examination at no distant date. where, though we may have suspected the foot, we have not been able to definitely assure ourselves that there the mischief is to be found, a further method of examination presents itself--namely, subcutaneous injections of cocaine along the course of the plantar nerves. the salt of cocaine used is the hydrochlorate, 2-1/2 grains for a pony, 4 grains for a medium-sized animal, and 6 grains for a large horse. a solution of this is made in boiled water (about 3 drams), and injected at the seat of the lower operation of neurectomy. it is advisable to first render aseptic the seat of operation, and to sterilize both the needle and the syringe by boiling. a suitable point to choose for the injection is exactly over the upper border of the lateral faces of the two sesamoids, the needle being introduced behind the cord formed by the nerve and accompanying vessels, and parallel with it. it is possible that the vein or the artery may be wounded, but such accident is of little importance. all that is necessary in that case is to partly withdraw the needle and again insert it. it is advisable to use a twitch. when the needle is in position, the injection should be made slowly, and at the same time the point of the needle should be made to describe a semicircular sweep, so as to spread the solution over as wide an area as is possible. anæsthesia ensues in from six to twenty minutes, and if the cause of the lameness is below the point of injection the animal moves sound. regarding this method of diagnosis, professor udriski of bucharest, after a series of trials, sums up as follows: 1. for the diagnosis of lameness cocaine injections are of very considerable value. 2. these injections should be made along the course of the nerves. 3. solutions heated to 40° or 50° c. produced quicker, deeper, and longer anæsthesia than equally strong cold solutions. 4. in the sale of horses cocaine injections conceal fraud. cocaine being an irritant, it must be remembered that after the anæsthesia the lameness is somewhat more marked than before. to the cocaine other practitioners add morphia in the following proportions: cocaine hydrochlorate 2-1/2 grains. morphia 1-1/2 " aqua destil 1-1/2 drams. as a diagnostic this mixture of the two is said to be far superior to either cocaine or morphia alone. in connection with this subject, professor hobday has published, among others, the following cases illustrating the practical value of this method of diagnosis:[a] [footnote a: the _journal of comparative pathology and therapeutics_ vol. viii., pp. 27, 43.] case i.--cab gelding. seat of lameness somewhat obscure; navicular disease suspected. injected 2 grains of cocaine in aqueous solution on either side of the limb, immediately over the metacarpal nerves. _five minutes_.--lameness perceptibly diminished. _ten minutes_.--lameness scarcely perceptible. case ii.--mare. obscure lameness; foot suspected. injected 30 minims of a 5 per cent. solution on either side of the leg just above the fetlock. _ten minutes_.--no lameness, thus proving that the seat of lameness was below the point of injection. case iii.--cab gelding, aged, free clinique; messrs. elme's and moffat's case. obscure lameness; foot suspected of navicular disease; very lame. injected 30 minims of a 5 per cent. solution of cocaine on either side of the leg over the metacarpal nerves. _six minutes_.--lameness perceptibly less; there was no response whatever on the inside of the leg to the prick of a pin. on the outside, which had not been injected so thoroughly, there was sensation, although not so much as in a healthy foot. _ten minutes_.--lameness had almost disappeared; so much so, that the opinion as to navicular disease was confirmed, and neurectomy was performed. immediately after this operation there was no lameness whatever. the same author also reports numerous cases among horses and cattle, dogs and cats, pointing out the toxic properties of the drug. the symptoms following an overdose are interesting enough to relate here, and i select the following case of professor hobday's as being fairly typical:[a] [footnote a: _loc. cit_.] case iv.--cart gelding. free clinique; navicular disease. injected subcutaneously over the metacarpal nerves on each side 6 grains of cocaine in aqueous solution. during the operation the animal manifested no signs of pain whatever, not even when the nerve was cut. this animal received altogether 12 grains of cocaine (3 grains were given on either side first, then fifteen minutes afterwards the same dose repeated). the effect was manifested on the system in ten minutes after the second injection by clonic spasms of the muscles of the limbs (the legs being involuntarily jerked backwards and forwards at intervals of about twenty seconds), which materially interfered with the performance of the operation. the animal was also continually moving the jaws, and was very sensitive to sounds, moving the ears backwards and forwards. this hyperæsthesia, as evinced by the movement of the ears, lasted for some considerable time after the animal had been allowed to get up. cocaine hydrochlorate solutions, if intended to be kept for any length of time, should have added to them when freshly made 1/200 part of boric acid in order to preserve them. even then they are liable to spoil, and should, for subcutaneous injection, be made up just before needed for use. chapter v general remarks on operations on the foot a. methods of restraint. many of the simple operations on the foot, such as the probing of a sinus, the paring out of corns, or the searching of pricks, may most suitably be performed with the animal's leg held by the operator as a smith holds it for shoeing. according to the temperament of the animal, even the operation for the removal of a portion of the sole, or the injection of sinuses with caustics, may be carried out with the animal simply twitched. when the operation is still a simple one, casting inconvenient or impossible, and the animal restive, the twitch must be supplemented by some other method. the most simple and one of the most effective is the blind, cap, or bluff (fig. 38). with it the most vicious animal or the most nervous is in many instances either cowed into submission or soothed into quietness. at the same time, more forcible means than the operator's own strength must be taken to hold the animal's foot from the ground. if the foot is a fore-foot, and the point desired to be operated on is to the outside, the pastern should be firmly lashed to the forearm by means of a thin, short cord, or a leather strap and buckle. much may then be done in the way of paring and probing that would otherwise be impossible. [illustration: fig. 38--the blind.] [illustration: fig. 39--the side-line.] if the foot is a hind one, one of the many methods of using what is termed by liautard, in his 'manual of operative veterinary surgery,' the plate-longe, must be adopted. this, in its most useful form, is a length of closely-woven cotton webbing, from about 2 to 2-1/2 inches wide, and from 5 to 6 yards long, provided with a small loop formed on one of its ends, and perhaps better known to english readers as a 'side-line.' if webbing be not available, a length of soft cotton rope, or a rope plaited and sold for the purpose, as fig. 39, will serve equally well. one of the most convenient methods of using the side-line for securing the hind-foot is depicted in figs. 40 and 41. [illustration: fig. 40.--the side-line adjusted preparatory to securing the near hind-foot.] [illustration: fig. 41.--the near hind-foot secured with the side-line.] here the side-line has formed upon it a loop sufficiently large to form a collar. this is placed round the animal's neck, the free end of the line run round the pastern of the desired foot, and the foot drawn forward, as in fig. 40. the loose end of the line is then twisted once or twice round the tight portion, and finally given to an assistant to hold (see fig. 41). the foot is thus held from the ground, and violent kicking movements prevented. where the operation is a major one, restraint of a distinctly more forcible nature becomes imperative. many of the more serious operations can most advantageously be performed with the patient secured in some form or other of stock or trevis, and the foot suitably fixed. it is not the good fortune of every veterinary surgeon, however, to be the lucky possessor of one of these useful aids to successful operating. perforce, he must fall back on casting with the hobbles (fig. 42). [illustration: fig. 42.--casting hobbles.] with the use of these we will assume our readers to be conversant, and will imagine the animal to be already cast. it remains, then, but to detail the most suitable means for firmly fixing the foot to be operated on. here the side-line is again brought into use. care should previously have been taken when casting to throw the animal so that the portion of the foot to be operated on, whether inside or outside, falls uppermost, and that the buckle of the hobble on that particular foot is placed so that it also is within easy reach when the animal is down. in the case we are illustrating the point of operation was the outside of the near hind coronet. we will, therefore, describe the mode of fixing the near hind-foot upon the cannon of the near fore-limb. [illustration: fig. 43.--photograph illustrating method of adjusting the side-line preparatory to fixing the hind-leg upon the fore.] the side-line is first adjusted as follows: it is fixed upon the cannon of the near hind-leg (a) by means of its small loop. from there it is passed under the forearm of the same limb, over the forearm, under the rope running from a to b; from there over and under the thigh, to be finally brought in front of the thigh, and below the portion of rope running from arm to thigh. the loose end of the side-line is then given to an assistant standing behind the animal's back, the buckle of the hobble restraining the foot unloosed, and strong but steady traction brought to bear from behind upon the line. the operator should now stand in front of the fore-limbs, and, by placing a hand on the rope passing round the arm, prevent the line from slipping below the knee. by this means the hind-limb is pulled forward until the foot projects beyond the cannon of the front-limb. when that position is reached, the operator grasps the hock firmly with one hand, and, directing the side-line to be slackened, gently slides downward the coils of rope round the arm and thigh until they encircle the cannons of both limbs. the cannon of the hind-limb is firmly lashed to the cannon of the fore, and the foot firmly and securely fixed in the best position for operating (see fig. 44). [illustration: fig. 44.--photograph showing the near hind-foot secured upon the cannon of the near fore-limb.] similarly, with the horse still on his off side, the off hind-limb may be fixed to the near fore, and the near fore and the off fore to the near hind. with the animal on his near side, we may fix the near hind and the off hind to the off fore, and the off fore and near fore to the near hind. the points to be remembered in fixing the limbs thus are: (1) the side-line should always commence upon the cannon of the limb to be operated on; (2) it should next pass under and over (or over and under, it is immaterial which) first the arm and then the thigh, or the thigh and the arm, as the case may be; (3) in every case, whether rounding the thigh and the arm from above or below, the piece of rope completing the round should always finish below that portion preceding it, so that traction upon it from behind the animal's back should tend to keep all portions of it from slipping below the knee and the hock. with the uppermost fore-limb secured to the hind-limb in the manner we have described, we have the underneath fore-limb suitably exposed for both the higher and lower operations of neurectomy. the position for this operation will be made better still if the lowermost limb (the one to be operated on) is removed from the hobbles and drawn forward by an assistant by means of a piece of rope fastened to the pastern. taking what we have described as a general guide, other modifications of thus securing the foot will suggest themselves to the operator to meet the special requirements of the case with which he is dealing. regarding the administration of chloroform, no description of the method is needed here, as it will be found fully detailed in most good works on general surgery. where great immobility is needed, it is one of the most valuable means of restraint we have. apart from that, its use in any serious operation is always to be advocated, if only on the score of humane consideration for the dumb animal helpless under our hands. b. instruments required. in addition to those required for operations on the softer structures--such as scalpels, forceps, artery forceps, directors, scissors, etc.--the surgery of the foot demands instruments specially adapted for dealing with the horn. a great deal will depend upon the operator as to whether these are few or many. the average man of resource will deem a smith's rasp and one or two strong drawing-knives amply sufficient, and on no account should they be omitted from the list of those ready to hand. [illustration: fig. 45.--the ordinary drawing-knife.] the ordinary smith's drawing-knife (fig. 45) is well known to almost everyone, and is well suited for much of the rougher part of the work. the careful following up of pricks, however, and some of the more special operations demanding removal of portions of the lateral cartilages call for instruments of a more delicate character and peculiar construction. these are to be found in the so-called sage-knife, and the modern (french) pattern of drawing-knife. [illustration: fig. 46. _a, b_, modern forms of drawing-knife; _c, d, e_, sage-knives.] the modern drawing-knife differs from the smith's instrument in being attached to a straight, instead of a curved, handle, and in usually being sharp on both edges instead of only on one. these are made in various sizes (fig. 46, _a, b_), and the blades flat, curved on the flat, or curved at an angle with the edges of the haft. the sage-knife, as its name indicates, is a knife with a lanceolate-shaped blade. these also may be obtained in varying forms and sizes (fig. 46, _c, d, e_). fig. 46, _c_, is a single-edged, right-handed sage-knife. fig. 46, _d_, is a left-handed instrument of the same type. the double-edged sage-knife is represented in fig. 46, _e_. [illustration: fig. 47.--symes's abscess-knife.] it may be mentioned too, in passing, that the ordinary symes's abscess-knife (fig. 47) is a most useful instrument when performing the operation of partial excision of the lateral cartilages, its peculiar shape lending itself admirably to the niceties of the operation. one or two good-shaped firing-irons will also be found useful. they will lighten the labour of tediously excavating grooves with the knife, where that procedure is necessary; and, used in certain positions to be afterwards described, will afford just that necessary degree of stimulus to the horn-secreting structures of the foot, which the use of the knife alone will not. the man in country practice will also be well advised in carrying to every foot case a compact outfit, such as that carried by the smith. this will consist of hammer and pincers, drawing-knife and buffer. much valuable time is then often saved which would otherwise be wasted in driving round for the nearest smith. there are other special operations requiring the use of specially-devised instruments for their successful carrying out. these we shall mention when we come to a consideration of the operations in which they are necessary. c. the application of dressings. one of the most common methods of applying a dressing to the foot is poulticing. usually resorted to on account of its warmth-retaining properties, the poultice may also be medicated. in fact, a poultice, strongly impregnated with perchloride of mercury or other powerful antiseptic, is a useful dressing in a case of a punctured foot, or a wise preliminary to an operation involving the wounding of the deeper structures. the poultice may consist of any material that serves to retain heat for the longest time. meal of any kind that contains a fair percentage of oil is suitable. crushed linseed, linseed and bran, or linseed-cake dust are among the best. to prepare it, all that is necessary is to partly fill a bucket with the material and pour upon it boiling water. the hot mass is emptied into a suitable bag, at the bottom of which it is wise to first place a thin layer of straw, in order to prevent the bag wearing through, and then secured round the foot. this is generally done by means of a piece of stout cord, or by straps and buckles fastened round the pastern and above the fetlock. an improved method of fastening has been devised by lieutenant-colonel nunn: 'a thin rope or stout piece of cord about 5 feet long is doubled in two, and a knot tied at the double end so as to form a loop about 5 or 6 inches long, this length depending on the size of the foot (as at a, fig. 48). the poultice or other dressing is applied to the foot, and the cloth wrapped round in the ordinary way, the loop of the cord being placed at the back of the pastern (as in a, fig. 49); the ends of the cord are passed round, one on the inside and the other on the outside, towards the front (as in b, fig. 49). these ends are then twined together down as far as the toe (see c in fig. 49). the foot is now lifted up, and the ends of the cord (cc, fig. 49), are passed through the loop a (as at d, fig. 49), and then drawn tight. the ends of the cord are now separated, and carried up to the coronet (as at ee, fig. 49), one on the outside, the other on the inside of the foot. they are then again twisted round each other once or twice (as at f, fig. 50), and are passed round the pastern once or twice on each side. they are now passed under the cord (e, fig. 49), and then reversed, so as to tighten up e, and are finally tied round the pastern in the usual manner. the arrangement of the cords on the sole is shown in fig. 51, which is a view from the posterior part. [illustration: figs. 48, 49, 50, 51.--illustrating lieutenant-colonel nunn's method of applying a poultice to the foot.] 'the advantages of this method of fastening have been found to be: (1) it does not chafe the skin; (2) if properly applied it has never been known to come undone; (3) it is the only way we know that a poultice can be satisfactorily applied to a mule's hind-foot; (4) horses can be exercised when the poultice is on the foot, which is almost impossible with the ordinary leather boot; (5) the sacking or canvas does not cut through so quickly.' [illustration: figs. 52, 53.--two forms of poultice-boot.] a further method of applying the poultice is by using one of the poultice-boots made for that purpose (see figs. 52 and 53). these have an objection. they are apt to be allowed to get extremely dirty, and so, by carrying infective matter from the foot of one animal to that of another, undo the good that the warmth of the poultice is bringing about. the advantage of the ordinary sacking or canvas is that it may be cast aside after the application of each poultice. where the boot is kept clean, however, it will save a great deal of time and trouble to the attendant. while on the subject of poulticing, it is well to remark that in many cases it may be more advantageous to supply the necessary warmth and moisture to the foot by keeping it immersed in a narrow tub of water maintained at the required temperature. by this means the warmth is carried further up the limb (sometimes an important point), and the water can more conveniently be medicated with whatever is required than can the poultice. in fact, it is the author's general practice, where the attendants can be induced to take the necessary pains, to always advise this latter method. [illustration: fig. 54.--swab for applying moisture to the foot.] where a dressing is relied upon by some practitioners on account of the warmth it gives, others, even in identical cases, will depend upon the effects of cold. this may be applied by means of what are called 'swabs.' in their simplest form swabs may consist only of hay-bands or several layers of thick bandage bound round the foot and coronet, and kept cool by having water constantly poured upon them. in many cases the form of swab depicted in fig. 54 will be found more convenient. when only one foot is required to be dressed, and a water-supply is available, by far the preferable method is to attach one end of a length of rubber tubing to the water-tap, and fasten the other just above the coronet, allowing the water to trickle slowly over the foot. in cases where a forced water-supply is unobtainable, and the case warrants the extra trouble, much may be done with a medium-sized cask of water placed somewhere over the animal, and the rubber tubing connected with that. where the dressing is desired to be kept applied to the sole and frog only, there is no method more satisfactory than the shoe with plates. [illustration: fig. 55.--the shoe with plates. _a_, the plates in position; _b_, the plates separated from the shoe.] [illustration: fig. 56.--the quittor syringe.] the plates are of metal, preferably of thin sheet iron or zinc, and are slipped between the upper surface of the shoe and the foot after the manner shown in fig. 55. the plates themselves are shaped as depicted in fig. 55, _a, b, c, a_ and _b_ curved to meet the outlines of the shoe, and _c_ shaped so as to wedge tightly over the posterior ends of the side plates, and between them and the shoe. a distinct advantage of the plate method of dressing is that a certain amount of pressure may be maintained on the sole and frog, a very important consideration in connection with some of the diseases with which we shall later deal. when dealing with sinuous wounds of the foot, another favourite mode of applying dressings is by means of the syringe, and no better instrument for all cases can be found than that known as a quittor syringe (fig. 56). a further mode of applying dressing, and one frequently practised in connection with the foot, is known as 'plugging.' this is almost sufficiently indicated by its name. it consists in rolling portions of the dressing into little cylinders, wrapped round with thin paper, and introduced into a sinus or other position where considered necessary. d. plantar neurectomy. as a last resort in the treatment of many diseases of the foot the operation of neurectomy is often advised. it will be wise, therefore, to insert a description of the operation here. _derivation of the word_.--for many years the operation was known simply as 'nerving' or 'unnerving,' and it was not until 1823, at the suggestion of dr. george pearson, that percival introduced the word _neurotomy_ to signify the operation with which we are now about to deal. the word neurotomy, however, used strictly, means the act or practice of dissection of nerves, and, when applied to the operation as practised to-day, describes only a step in the procedure. as the operation really consists in cutting down upon, and afterwards excising a portion of the nerve, the modern appellation of _neurectomy_--from the greek _neuron_, a nerve; and _tome_, a cutting, signifying the cutting out of a nerve or the portion of a nerve--is far more suitable. according as the nerve operated on is the plantar or the median, the operation is known as plantar or median neurectomy. _history of the operation_.--it is to two english veterinarians that we owe the introduction of the operation to the veterinary world. in 1819 professor sewell announced himself as the originator of neurotomy. this claim was disputed by moorcraft, who appears to have successfully shown himself to be the real person entitled to that honour, he having satisfactorily performed the operation on numerous animals for fully eighteen years prior to professor sewell's announcement. it appears that moorcraft left this country for india in 1808, having practised the operation in more or less obscurity for some six or seven years previous to that. after his departure neurectomy, as introduced by him, either died away in repute, or was not made by him sufficiently public to become a matter of general knowledge. to professor sewell, therefore, although not the actual originator of the operation, belongs the honour of making it public to the veterinary profession. in 1824, five years after sewell's introduction, we find it practised on the continent by girard. we gather, however, from the writings of percival and liautard, that both in this country and on the continent the operation was for several years largely in the stage of experiment. unsuitable subjects were operated on; the work afterwards given to the animal improperly adjusted to his altered condition; and the bad after-results of the operation almost ignored by some, and greatly exaggerated by others. in fact, some long time elapsed before veterinary surgeons allotted to the operation that measure of credit which the results following it warranted. _the object of the operation_ is to render the foot insensitive to pain, and to give to an otherwise incurably lame animal a further period of usefulness. after the operation, as time goes on, this object may become defeated by the reunion of the divided ends of the nerve. in that case, neurectomy must necessarily be performed again. _the operation_.--two forms of neurectomy are recognised--the high operation and the low. the low operation deals with the posterior digital branch of the plantar nerve, and the high operation with the plantar itself. it is the latter operation with which we shall deal first. in our opinion it is that most likely to be followed by satisfactory results. the area supplied by the posterior digital is mainly the posterior portion of the digit. thus, unless the cause of the lameness is diagnosed with certainty to be situated somewhere in the posterior region of the foot, section of the posterior digital alone will not give total insensibility to pain. added to that, we may remember this: below the point at which the digitals branch off from the plantar there is always more likelihood of the part we are attempting to render insensible being supplied by another and adventitious branch, or a branch that, as regards its direction, is abnormally distributed. as a last consideration, we may say that the higher operation is the easier to perform. percival, in his works on lameness, has some very sage remarks to make by way of a preliminary, and we cannot do better than quote them here. he says: 'to command success in neurectomy three considerations demand attention: '1. the subject must be fit and proper; in particular, the disease for which neurectomy is performed should be suitable in kind, seat, stage, etc. '2. the operation must be skilfully and effectually performed. '3. the use that is made of the patient afterwards should not exceed what his altered condition appears to have fitted him for. 'the veterinarian who is guided by considerations such as those will find that he has restored to work horses who would otherwise have been utterly useless. a plain and safe argument wherewith to meet the objections to neurectomy is simply to ask the question what the animal is worth, or to what useful purpose he can be put, that happens to be the subject of such an operation. 'if the horse can be shown to be still serviceable and valuable, then he is not a legitimate subject for the operation. the rule of procedure i have laid down is to operate on no other but the _incurably lame horse_; and whenever this has been attended to, not only has success been the more brilliant, but indemnification from blame or reproach has been assured.' _preparation of the subject_.--but little in the way of medicinal preparation is necessary. when the animal is a gross, heavy feeder, and carries a more than ordinary amount of cupboard, all that is needed is to withhold his usual allowance of food for some time prior to the operation, simply to avoid risk of rupture when casting. if considered advisable, a dose of physic may also be administered. to the seat of operation, however, careful attention should be given. on the day previous to the operation the hair should be closely removed with the clipping machines, and the skin thoroughly cleansed with warm water and soap. after this, a bandage soaked in a 4 per cent, watery solution of carbolic acid should be wrapped lightly round the limb, and allowed to remain in position until the animal is cast and ready for the operation the following morning. on removing the bandage prior to operating, the part should again be bathed with a cold 5 per cent. solution of carbolic acid and swabbed dry. attention to these details will serve to leave the wound in that favourable condition in which it heals nicely, and with the minimum amount of trouble. _preliminary steps_.--by some practitioners the operation is performed with the animal standing, local anæsthesia having been first obtained by the use of cocaine, or an ethyl chloride spray. there is no gainsaying the fact, however, that the operation of neurectomy is a painful one, and that, with most operators, success will be more fully guaranteed with the animal cast and the limb held in a suitable position by an assistant. the animal is thrown by the hobbles upon the side of the leg which is to be operated on. the cannon of the upper fore-limb is then fixed to the cannon of the upper hind, as described under the section of this chapter devoted to the methods of restraint, and the lower limb freed from the hobbles and drawn forward by an assistant by means of a stout piece of cord round the pastern. an alternative method of holding the limb is to bind both fore-legs together above the knee by means of the side-line run round a few times in the form of the figure 8, and then fastened off. as in the former method, the lower foot is then removed from the hobble, and again held forward by an assistant. by either method the inside of the limb is operated on first. [illustration: fig. 57.--the esmarch rubber bandage and tourniquet.] although it is not absolutely necessary, it is an advantage, especially to the inexperienced operator, to apply before operating an esmarch's bandage and tourniquet (fig. 57). this expels the greater part of the blood from the limb, and renders the operation comparatively bloodless. [illustration: fig. 58.--rubber tourniquet with wooden block.] the esmarch bandage is composed of solid rubber, and with it the limb is bandaged tightly from below upwards. on reaching the knee the tourniquet is stretched round the limb, fastened by means of its buckle and strap, and the bandage removed. those who feel they can dispense with the bandage use the tourniquet alone. for this purpose the form depicted in fig. 58, and the one in general use at the royal veterinary college, is more suitable, on account of its wooden block, which may be placed so as to press on the main artery of supply. [illustration: fig. 59. neurectomy bistoury.] _instruments required_.--these should be at hand in an earthenware or enamelled iron tray containing just sufficient of a 5 per cent. solution of carbolic acid to keep them covered. those that are necessary will be a sharp scalpel, or, if preferred, one of the many forms of bistoury devised for the purpose (see fig. 59), a pair of artery forceps, a needle ready threaded with silk or gut, one of the patterns of neurectomy needle (see fig. 60), and a pair of blunt-pointed scissors curved on the flat. it is also an advantage, when once the incision through the skin is made, to employ one of the forms of elastic, self-adjusting tenacula (see fig. 61) for keeping the edges of the wound apart while searching for the nerve. [illustration: fig. 60. neurectomy needle.] _incision through the skin_.--we remember that the plantar nerve of the inner side is in close relation with the internal metacarpal artery, and that both, in company with the internal metacarpal vein, run down the limb in close proximity with the inner border of the flexor tendons. also, we remember that the external plantar nerve has no attendant artery, although, like its fellow, it is to be found in close touch with the edge of the flexor tendons. bearing these landmarks in mind, we feel for the nerve in the hollow just above the fetlock-joint by noting the pulsations of the artery, and determining the edge of the flexor tendons. this done, a clean incision is made with the bistoury or the scalpel in the direction of the vessels. the incision should be made firmly and decisively, so that the skin may be cleanly penetrated with one clear cut. if judiciously made, little else in the shape of dissection will be needed. [illustration: fig. 61.--double tenaculum.] it is now that the double tenaculum (fig. 61) is applied. one clip is fixed to the anterior edge of the wound, and the other carried beneath the limb and made to grasp the posterior edge. if found desirable to keep the edges of the wound apart, and no tenaculum to hand, the same end may be accomplished by means of a needle and silk. in like manner as is the tenaculum, the silk is attached to one edge of the wound, carried under the limb, and firmly secured to the other. having made the incision, the wound should be wiped free from blood by means of a pledget of cotton-wool previously soaked in a carbolic acid solution and squeezed dry. at the bottom of the wound will now be seen the glistening white sheath, containing the vein, artery, and nerve. this should be picked up with the forceps, and a further incision made with the bistoury. care should be exercised in making this second incision, or the artery may accidentally be opened. if an ordinary scalpel is used, the lower end of the sheath should be picked up and the point of the scalpel inserted through it. with the cutting edge of the scalpel turned towards the opening of the wound, the sheath is then slit from below upwards. the second incision satisfactorily made, the wound is again wiped dry, and the nerve seen as a piece of white, curled string in the posterior portion of the wound. at this stage it is advisable to accurately ascertain whether what we have taken to be the nerve actually is it. this is done by taking it up with the forceps and giving it a sharp tweeze. a sudden struggle on the part of the patient will then leave no doubt in the operator's mind that it is the nerve he has interfered with. _section of the nerve_.--the neurectomy needle (fig. 60) is now taken, and, excluding the other structures, passed under the nerve. a piece of stout silk or ordinary string is then threaded through the eye of the needle, the needle withdrawn, and the silk left in position under the nerve. the silk is now tied in a loop, and the nerve by this means gently lifted from its bed. with the curved scissors or the scalpel it is severed as high up as is possible. the lower end of the severed nerve is then grasped firmly with the forceps, pulled downwards as far as possible, and then cut off. at least an inch of the nerve should be excised. the animal is then turned over, and the opposite side of the limb operated on in the same manner. the tourniquet is now removed, and the wound is examined for bleeding vessels. if the hæmorrhage is only slight, the wound should be merely dabbed gently with the antiseptic wool until it has stayed. a larger vessel may be taken up with the artery forceps and ligatured, or the hæmorrhage stopped by torsion. on no account, unless it it done to stay hæmorrhage that is otherwise uncontrollable, should the wound be sutured with blood in it. with the wound once dry and clean, it is well to insert three or four silk sutures, but care must be taken not to draw them too tightly. this done, the patient may be allowed to get up. _after-treatment_.--this is simple. over each wound is placed a pledget of antiseptic cotton-wool or tow, and the whole lightly covered with a bandage soaked in an antiseptic solution. for the first night the animal should be tied up short to the rack, and the following morning the bandages removed. a little boracic acid or iodoform, or a mixture of the two combined with starch (starch and boracic acid equal parts, iodoform 1 drachm to each ounce) should now be dusted over the wounds, the antiseptic pledgets renewed, and the bandage readjusted over all. at the end of three or four days the bandages may be dispensed with. all that is necessary now is an occasional dusting with an antiseptic powder, and, as far as possible, the restriction of movement. at the end of a week the sutures may be removed, and the animal turned into a loose box or out to pasture. e. median neurectomy. as a palliative for lameness when confined to the foot, one would imagine that the plantar operation would be all sufficient. there are operators, however, who state that the results following section of the median nerve have been such as to cause them to entirely abandon the lower operation in its favour. if only for that reason a brief mention of the operation must be made here. the operation was first performed in this country in october, 1895, the subject being one of the out-patients at the royal veterinary college free clinique. for five or six years following this date professor hobday performed the operation some several hundred times, and was certainly instrumental in bringing the operation into prominence. though so recently introduced here, it appears to have been practised for several years on the continent, originating in germany as early as 1867. in that country a first public account of it was published in 1885 by professor peters of berlin, while in france it was introduced by pellerin in 1892. in this operation a portion of the median nerve is excised on the inside of the elbow-joint just below the internal condyle of the humerus. here the nerve runs behind the artery, then crosses it, and descends in a slightly forward direction behind the ridge formed by the radius. the position of the limb most suitable for the operation is exactly that we have described as most convenient for the plantar excision. the animal is cast, preferably anæsthetized, and the limb removed from the hobbles, and held as far forward as is possible by an assistant with the side-line. professor hobday's description of the operation is as follows: 'a bold incision is made through the skin and aponcurotic portion of the pectoralis transversus and panniculus muscles, about 1 to 3 inches (depending on the size of the horse) below the internal condyle of the humerus, and immediately behind the ridge formed by the radius. this latter, and the nerve which can be felt passing over the elbow-joint, form the chief landmarks. the hæmorrhage which ensues is principally venous, and is easily controlled by the artery forceps. in some cases i have found it of advantage to put on a tourniquet below the seat of operation, but this is not always advisable, as it distends the radial artery. we now have exposed to view the glistening white fascia of the arm, which must be incised cautiously for about an inch. this will reveal the median nerve itself situated upon the red fibres of the flexor metacarpi internus muscle. if not fortunate enough to have cut immediately over the nerve, it can be readily felt with the finger between the belly of the flexor muscle and the radius.'[a] [footnote a: _journal of comparative pathology and therapeutics_, vol. ix., p. 181.] the nerve exposed, the remainder of the operation is exactly as that described in removing the portion of the nerve in the plantar operation. the wound is sutured and suitably dressed, and a fair amount of exercise afterwards allowed the patient. f. length of rest after neurectomy. this is placed by the majority of surgeons at about three weeks to a month. within that period no excessive exertion should be undergone by the patient. a certain amount of quiet exercise, however, is beneficial, facilitating the healing of the wounds, and accustoming the animal to the altered condition of his limb. g. sequelæ of neurectomy. these we shall relate collectively, making no distinction between those following excision of the plantar nerve and those succeeding section of the median. it must be remembered by the surgeon, however, that the unfortunate sequelæ we are now about to describe are likely to be far more grave when following section of the larger nerve. _liability of pricked foot going undetected_.--on account of the warning they convey to the surgeon, first place among the sequelæ of neurectomy must be given to accidents following loss of sensation. take, for example, punctured foot. in any case, in the sense of being unforeseen, it is accidental. in the neurectomized foot it becomes doubly accidental, in that not only is it unforeseen, but that it is for some time indiscoverable. with the foot deprived of sensation, a nail may be picked up, or a prick sustained at the forge, and no intimation given to the attendant until pus has underrun the horn, and broken out at the coronet. what follows, then, is that the hoof as a whole, or the greater part of it, sloughs off. no neurectomy should be undertaken unless this contingency has been allowed for. the owner should be advised of it by the surgeon, who should at the same time enjoin on his client the absolute necessity of giving to the neurectomized foot daily and careful attention. _loss of tone in the non-sensitive area_.--in addition to the mischief resulting from a wound going undetected, it must be remembered that the loss of tone resulting from the operation gives to every wound (however slight), in the region supplied by the removed nerve, a sluggish and troublesome character. difficult to deal with as wounds about the foot ordinarily are, they are rendered more so by a previous neurectomy. _gelatinous degeneration_. this is a condition liable to occur in cases where the operation has been too long deferred, and when considerable structural alteration has already taken place in the shape of diseased bone or tendon, more especially in navicular disease. it consists in a peculiar softening of the structures of the limb, accompanied with enlargement, due to swelling of the connective tissues, the enlargement and softening generally making itself first apparent by a soft, pulpy swelling in the hollow of the heel. from this onwards the enlargement increases, and lameness becomes excessive, the animal going more and more on his heels, until, finally, no portion of the solar surface of the foot comes to the ground at all. the case is hopeless, and destruction should be advised. _reported case_.--'the patient, a brown carriage gelding, was brought to the royal veterinary college infirmary in a cart on december 31, the only previous history obtainable being that it had suddenly fallen lame a month before. 'the symptoms presented were excessive lameness of the near fore-limb. on being trotted, the toe was elevated each time the foot reached the ground, progression being entirely on the heels. separation of the hoof for about 2 inches at the hinder part of the coronet; oedematous swelling from foot to knee, extending during the next three days to the elbow. great tenderness between the knee and the fetlock; below this no sensation whatever, as a pin was inserted in several places round the coronet without causing any symptoms of pain. on further examination, two unnerving scars were found. no treatment was adopted, and the horse was destroyed on january 6. 'on dissecting the leg, the following appearances presented themselves: 'the limb was very much enlarged, due to thickening of the connective tissue, the skin being removed only with difficulty. the tendons were soft and much thickened. a rupture of the skin at the coronet, just where the skin meets the wall of the foot. large extravasations of blood at the back of the tendons, situated in the lower half. _external_ nerve trunk had become reunited, at the point of junction there being a hard lump about the size of a walnut. _internal_ nerve trunk also had become reunited, and presented a thickened portion at the point of junction, but not so large as that of the outer side, and situated in the lower half of the tendon, about 2 inches higher than that on the external nerve. this nerve trunk was atrophied below the thickening, and had undergone gelatinous degeneration. judging from the scars on the skin, this side had evidently been unnerved a week or ten days previously to that on the outer side. the band stretching across the back of the perforatus, between the external and internal nerves, appeared on the inside to have become firmly fixed into the tendon. 'on removing the hoof, under the sole there appeared a large quantity of very foetid pus; the laminæ were very much inflamed in patches. there was an enormous thickening of connective tissues in the heel. on cutting longitudinally through the perforatus tendon, there was exposed a large blood-coloured mass, of a gelatinous appearance, situated on the perforatus tendon, the latter being very much thickened, and growing to the navicular bone. the underneath surface of the superior suspensory ligament was much thickened, and firmly adherent to the bone; at the posterior surface of the metacarpus there was a quantity of gelatinous substance. the anterior ligament of the fetlock-joint was thickened; the navicular bone was entire, but showed lesions of navicular disease, being ulcerated. section through the bone did not reveal anything further. it may be here remarked that the ulcerations were on either side of the central ridge, and not at all on the ridge itself. 'microscopic examination of the tissue joining the two ends of the nerve together revealed a few nerve fibres; the general appearance was that of granulation tissue, containing capillary vessels, which were fairly plentiful, and comparatively large in size.'[a] [footnote a: _veterinary record_, vol. iv., p. 386 (hobday)] _chronic oedema of the leg_.--in some cases there is a distinct swelling of the leg some time after the operation. this exposes the limb to the infliction of sores from striking with the opposite foot, with, of course, the difficulty in healing we have just described. _persistent pruritus_.--this annoying sequel occurs in the neurectomized limb, with or without gelatinous degeneration, and appears to be without a remedy. the itching in some cases is so intense as to lead the animal to constantly gnaw at the top of the foot. as one observer has remarked, the animal may begin literally biting pieces out of his limb. the result of the irritation and gnawing is fatal. great sloughing of the parts takes place, and the animal has eventually to be slaughtered. _fracture of the bones_.--the sudden loss of sensation in a foot may cause the animal to use violently the limb he has for months past been carefully nursing. it may be that the lameness for which the operation has been performed has been due to disease existing in the navicular bone, and extending, perhaps, to the os pedis. by the disease the bone has already been made brittle, its substance and ligamentous attachments perchance weakened and broken up by a slow-spreading caries, and rarefaction of the remaining bone substance rendered almost certain. in this instance, the free use of the foot, and the application to the diseased structures of an unwonted pressure immediately after the operation results in fracture. with the rupture of the structures we get the elevated toe and soft swelling in the heel, as described in gelatinous degeneration. treatment, of course, is out of the question. _neuroma_.--a further sequel is the appearance at the seat of the operation of what is termed an 'amputational neuroma.' this is a tumour-like growth occurring on the end of the divided nerve. it is composed of connective-tissue elements permeated by nerve fibres which have grown out from the axis-cylinders of the nerve stump. it may vary in size from a pea to a hazel-nut, and is frequently the cause of much pain. this must be cut down upon and cleanly removed, taking away at the same time as much of the nerve as is possible. _reunion of the divided nerve_.--we may say at once that 'reunion' in the popular sense of the word does not take place. at a varying period after section, however, we do get a return of sensation. this is brought about in the following manner: the axis-cylinder of the nerve, still in connection with the spinal cord, swells somewhat, and hypertrophies. the cells of this hypertrophied portion show a great tendency to proliferate and produce new nerve structure. this growing point splits, and gives rise to several fibrils, which are new axis-cylinders. these commence to grow towards the periphery, and, in so doing, grow through the cicatricial tissue that has formed at the seat of the operation. after passing through the cicatricial tissue (the amount of which tissue, of course, controls the length of time that insensibility remains), the growing axis-cylinders reach the degenerated portions of the nerve below the point of section. it is along the track of the old nerve that the new growths from the stump reproduce themselves. the fact of the new growths having to pass through the fibrous tissue of the cicatrix before they can gain the course of the old nerve, along which latter their progress of growth is comparatively easy, affords ample illustration that as large a portion as is possible of the nerve should be removed when operating, in order to convey insensibility for the longest time. after reunion, of course, nothing remains but to repeat the operation. _the existence of an adventitious nerve-supply_.--while not exactly a sequel of the operation, the fact that it is not discovered until after the operation has been performed warrants us in mentioning it here. it is not an uncommon thing in the lower operation to find that sensation and symptoms of lameness still persist after section of the nerve. in many cases this has been traced to the existence of an abnormal nerve branch. in the higher operation this is not so likely to be met with. that it may occur, however, is shown by the following interesting case related by harold sessions, f.r.c.v.s.:[a] [footnote a: _journal of comparative pathology and therapeutics_, vol. xii., p. 343.] 'in june of 1898 i saw a hunter suffering from navicular disease. after carefully examining the leg, i advised the owner to have the operation of neurectomy performed upon him. this he decided to do, and the horse was sent to me about the beginning of july. [illustration: fig. 62.--dissected external metacarpal nerve and branches. _a_, metacarpal; _b_, anterior plantar; _c_, extra branch (probably from the internal metacarpal), conveying sensation after division of the external metacarpal.] 'the operation was performed in the ordinary way, without any difficulty whatever. the wounds healed nicely, but the horse still continued to go lame. careful examination showed that there was still sensation on the outside of the foot. thinking that possibly there might be two external metacarpal nerves, the horse was again cast, the operation being performed slightly lower down. only the main branch of the external metacarpal nerve could be found. a piece of this was taken out, and the horse let up. on examination, sensation was still found in the posterior part of the outside of the foot. it was very evident that there was some abnormal distribution of the nerve, as sensation was still being conveyed to that part of the foot. 'as the horse was absolutely useless, and would have to be shot unless this piece of nerve could be found, he was again thrown, and after he had been anæsthetized i determined to follow the course of the nerve down, until i found where the accessory branch came from. this i found a little below the fetlock, about 1/2 inch below the point where the anterior plantar nerve is given off from the metacarpal nerve. it was about 1/2 inch below the spot where the anterior plantar nerve passes between the artery and vein of the foot, and it was somewhat difficult to get at it. 'fig. 62 shows the exact size and distribution of the nerves. after the separation of the accessory branch, sensation was taken from the foot, and the horse went perfectly sound.' _stumbling_.--in addition to the sequelæ we have mentioned, it is urged against the operation of neurectomy that one of the first effects of depriving the foot of the sense of touch is a tendency on the part of the animal to stumble. from the cases we have seen we cannot regard this objection as a serious one. nevertheless, as veterinarians, with a knowledge of the physiology of the structures with which we are dealing, we must treat the objection with respect, for, after all, we are bound to allow that stumbling, and a bad form of it, would be but a natural sequence of the operation we have just performed. the real fact remains, however, that cases of stumbling, even immediately after the operation, are rare; and that even when they do occur, the animal seems easily able to accommodate himself to the altered condition, and as readily uses the comparatively inert mass at the end of his limb as he did previously the intact foot. h. advantages of the operation. from the prominence we have given to the unfortunate sequelæ of the operation it might possibly be inferred that, while not giving it our absolute condemnation, we regard neurectomy with a certain amount of distrust. that we may contradict any such false impression, we state here that in many cases the operation is the only measure which will offer relief from pain, and restore to work an otherwise useless animal. in support of that we will now quote the recognised advantages of the operation. that in many cases, when all other methods--surgical and medicinal--have failed, there is an immediate and total freedom from pain and lameness no one will deny. this, if it restores to active work an animal that would otherwise have had to have been cast aside, is ample justification for giving the operation, in spite of its many unfortunate terminations, a real place among the more highly favoured remedial measures to our hand. 'for _contracted hoofs_, viewing them in the light of idiopathic disease, or as being the immediate cause of the existing lameness in the uninflamed condition of the foot, and when consequential changes of its organism have taken place which bid defiance to therapeutic measures, _neurotomy_ is a _warrantable resource_' (percival). 'for _ringbone_ neurotomy has been practised with perfect success, after blistering and firing had both failed, notwithstanding the work the animal had to perform afterwards was of the most trying nature' (_ibid_.). for _navicular disease_, when that malady is diagnosed, the earlier neurectomy is performed the better. the greater work given to the diseased bursa and bone, and the return of the contracted heels to the normal, brought about by the greater freedom with which the foot is used, are claimed by many to effect a cure. writing of navicular disease, and mentioning his belief in the possibility of the diseased bone effecting its own repair after the operation, harold leeney, m.r.c.v.s., says: 'the expansion of the heel, and rapid development of the frog (in this and many other cases) immediately after the operation, has not, i venture to think, attracted so much attention as it deserves, and may have something to do with those cases which appear to be actually _cured_, not merely made to go sound by absence of pain.'[a] [footnote a: _veterinary record_, vol. xi., p. 297.] speaking of the median operation before a meeting of the central veterinary medical society, professor hobday says:[a] [footnote a: _veterinary record_, vol. xiii., p. 427.] 'for old-standing lamenesses, when due to splints, exostoses, chronically sprained, thickened, and painful perforans and perforatus tendons, or cases of that kind which cause pain by pressing on the adjacent nerve structures, after all other known methods have failed, median neurectomy is the operation which will be most likely to give the animal a new lease of life and usefulness.' 'of the _humanity and utility of neurectomy_ there can be no question whatever, and provided the cases are well selected, and the operation is efficiently performed, the advantages to be derived from it are most striking as well as enduring. but the disadvantages attending the loss of sensation in the foot have been brought forward on many occasions as an argument against neurectomy, and no one can deny that the foot with sensation is better than one without that faculty. but in a long experience of the operation i have never found these disadvantages outweigh the great advantages which have immediately followed it.'[a] [footnote a: _veterinary journal_, vol. ix., p. 178 (fleming).] beyond these, the direct advantages of neurectomy, are other and more indirect advantages which claim attention. the most astonishing among them is the fact noted by many writers of repute that exostoses (ringbones, side-bones, splints, etc.) rapidly diminish in size. this is vouched for by such well-known authorities as zundel and nocard. percival, too, mentions at some length the effect of the removal of pain on the oestral and generative functions, quoting a case of a brood cart-mare by reason of bony deposits being stayed from breeding for some years. two months after the operation she went to work, and moved sound, her altered condition leading her to breed several healthy foals. i. the use of the horse that has undergone neurectomy. no operation is of any considerable value to the veterinary surgeon unless he is able to show that after it he has left his patient workable. the alleviation of pain alone, commendable as it is from a humanitarian standpoint, is of no interest to the average owner of horse-flesh, unless with it he sees his animal capable of justifying his existence by the amount of labour performed. criticised in this way, is the operation of neurectomy justifiable? upon that point the opinions of many practitioners, even at the present day, differ. we have already partly answered the objections likely to be raised on this score by stating that the work afterwards allotted the animal should be fixed to suit his altered condition. it may be taken as a general rule that in all cases where the animal's usefulness depends upon his delicacy of touch, as, for example, animals used solely for hacking or hunting, his future usefulness in that special sphere of work will be done away with. percival himself, always a strong advocate for the operation, fully recognises this. 'does the neurotomized horse maintain the same step as before?' he asks. 'to this important question,' he replies, 'i unhesitatingly answer no; he does not. there can be no doubt but that the horse _feels_ the ground upon which he is treading, and that he regulates his action in consonance with such feeling, so as to render his step the least jarring and fatiguing to himself, and therefore the easiest and pleasantest to his rider.... such impressions'--those of touch--'being in the neurotomized subject, so far as regards the feeling of the foot, altogether wanting, a bold, fearless projection of the limb in action will be the consequence, followed by a putting down of the hoof flat upon the ground, as though it were a block, creating a sensation alike unpleasant both to horse and rider.' emphatic as percival is upon this point, there are, nevertheless, others who maintain with equal stoutness that the unnerved animal is positively as safe, if not safer, than the animal who has not been so treated. 'that the tactile sense in the horse's foot is useful, it would be idle to deny; but that it is absolutely essential, even to safe progression, no one who has paid attention to the results of plantar neurectomy will maintain. on several occasions for years i have hunted, hacked, and driven horses which have been deprived of sensation in their fore-feet, and never had an accident with them. their action has not been impaired by the operation; on the contrary, it has been vastly improved compared with what it had been previous to it. and my opinion has not been single in this respect, as many competent horsemen can give like evidence after long and severe trials of neurotomized horses. the opponents of neurotomy were, probably, not aware that there is in progression a _muscular_ as well as a _tactile sense_.' this latter contention is supported by numerous cases, reported at the time when the operation of neurectomy was at the heyday of its popularity. two i select from writings of a later period: _recorded cases_.--1. 'two of the finest among the many fine horses in the second life guards were so lame from navicular disease, when i joined the regiment, that they were unsafe and unsightly to ride, and were therefore entered on the list to be cast off and sold. one was so crippled that it could scarcely be moved out of its stable. peeling sorry at having to get rid of such good horses, and anxious to give another blow to the mistaken theory that unnerved animals were unsafe, i obtained the consent of my commanding officer, who patronizes practical conclusions, to perform neurotomy. this was carried out on both horses about eighteen months ago. within a fortnight they were at their duty, absolutely free from lameness, and with first-rate action, and one of them, from being troublesome and unsteady in the ranks--probably from the pain in its feet--had become quite steady and tractable. instead of being lame, blundering, and unsafe, both were sound, free in movement, and secure, and, the pain being abolished, they looked improved in condition. 'during the month of july the regiment attended the summer drills at aldershot, and five days every week for a month these horses carried a weight of about 22 stones each over the roughest and most dangerous ground, nearly always at a fast pace, and for four, five, or six hours each day; and yet they never fell or blundered, and the troopers who rode them had unbounded confidence in their sure-footedness. they returned to windsor, at the end of the month's severe test, as sound in their paces as when they left, and certainly now offer no indication whatever that they are less safe to ride than any other horse in the regiment. the effects of the relief from pain are also most marked, not only in the altered gait out of doors, but also in the stable.'[a] [footnote a: _veterinary journal, vol_. ix., p. 178 (george fleming, f.b.c.v.s.).] 2. 'some years ago i operated upon a valuable hunter, the property of a gentleman in kildare, the animal having shown unmistakable symptoms of navicular disease for some months previously, and which had been unsuccessfully combated by the milder forms of treatment for the disease without any benefit. although the horse went sound, the owner feared to ride him, and sent him to be sold in dublin, where he was disposed of for a small price, and i then lost sight of him. the following punchestown races, to my surprise, amongst a group of horses walking round the paddock previous to saddling for an important race, i recognised my old patient, bandaged, clothed, and trained, ready to take his part in the cross-country contest, and surrounded by a host of admirers willing to back him at any price. 'having satisfied myself that it was no other than the same animal, my first impulse was at once to find out the jockey who was to ride him, and warn him of his danger by telling him his mount was devoid of feeling in both fore-feet; but the saddling-bell had already rung, and in a few moments more the jockey emerged from the weighing-room and the next view of the horse was his tearing up the course in the preliminary, and "pulling double." i was sorry for the jockey if he felt as i did at that moment, for if he did i fear he and his horse would have parted company at the first fence, as i was certain there would be a smash before the end of the long and difficult three miles of the kildare hunt cup course. it was not until i saw him again in the front rank passing the stand, in the first round, that i breathed freely, and even then i felt very guilty, and, had he come to grief badly, i don't think i should ever have operated on another horse except in such a way as would have left unmistakable traces after it. '"the old horse wins!" screamed a thousand voices as the competitors safely cleared the last bank (now taken away for a gorse fence) the last time round, and from that moment the operation went up in my estimation a hundredfold, and i almost lost all interest in the finish (and it was a close one, with my patient a good third), resolving i would operate for the future on every animal, young and old, which showed symptoms of navicular disease. 'neither owner nor jockey knew the horse had been operated on, and he was soon after, on the strength of his performance, sold for a good price to come to england. it is idle to think that all cases are as successful as this was, as experience soon told me; but i consider that, in careful hands, the advantages well outweigh the disadvantages of the operation, and i have selected this instance merely as a practical example.'[a] [footnote a: _veterinary journal_, vol. iii., p. 254 (w. pallin, m.b.c.v.s.).] it is solely with the object of ventilating both sides of the question that we quote the last two cases. in our opinion, the colours in which the results of the operation are there painted are far too rosy. the practitioner who has before him the task of satisfying a client as to what will or what will not be the results of an operation he has suggested will do well to weigh each side of the argument carefully, and endeavour in his explanation to strike the happy mean. we hold, further, that the animal who has previously been accustomed to fast work, and to work entailing a large call upon the sense of touch when passing over rough and uneven ground, will be far more likely, in his neurectomized condition, to give satisfaction to his owner if put to a slower and a more suitable means of earning his living. chapter vi faulty conformation under this heading we shall deal with such formations of the feet as depart sufficiently from the normal to render them serious. faulty conformation may be either congenital or acquired, and acquired gradually as the result of slowly operating causes, or suddenly as the sequel to previous acute disease. whether congenital or acquired, serious in its nature or comparatively of no account, the veterinary surgeon will often find that the matter of conformation is one which will have a direct bearing on many of his 'foot' cases, and, furthermore, that it is one upon which he will often be called to give advice. a. weak heels. _definition_.--that condition of the wall in which, owing to the softness of the horn and the oblique direction of the horn fibres, the heels are unable properly to bear the body-weight, and, as a consequence, curve in beneath the sole. we give the condition first mention, not because of its greater importance, but for the reason that it is frequently the forerunner of the condition to be next described--namely, contracted feet. _symptoms_.--the extreme point of the heel is not affected unless the foot has been greatly neglected, and the condition allowed to develop. where, however, the foot has been uncared for, curving in of the wall takes place to an alarming degree, and the heels curl underneath the foot to such an extent as to grow over the sole and the bars. by the pressure they exert on the sole corns result, and the animal is lamed. _causes_.--in the main this defect is hereditary. it is seen commonly in connection with flat-foot, and where the horn of the wall is thin and shelly. _treatment_.--in the case of weak or 'turned in' heels no suitable bearing is offered for the shoe in the posterior half of the foot. any attempt to induce the heels to bear weight is immediately followed by their bending in. it follows from this that the best shoe to be used here is one in which the bearing is confined to the anterior half of the wall, the heels being relieved by being sufficiently pared. as might be expected, this bearing on the anterior half only of the foot is insufficient; pressure must be given the frog. this latter end is best gained by a bar shoe (fig. 68). with it the anterior portions of the wall, the whole of the bars, and the whole of the frog may be in contact, and the heels only so pared as to take no bearing at all. a few such shoeings sees the defect remedied. in every instance paring of the sole should be discouraged, as it serves but to increase the deformity. b. contracted foot. _(a)_ general contraction--contracted heels. _definition_. by the term contracted foot, otherwise known as hoof-bound, is indicated a condition in which the foot, more especially the posterior half of it, is, or becomes, narrower from side to side than is normal. it must be borne in mind, however, that certain breeds of horses have normally a foot which nearer approaches the oval than the circular in form, and that a narrow foot is not necessarily a contracted foot. the contraction may be bilateral when affecting both heels of the same foot and extending to the quarters, or unilateral when the inside or outside heel only is affected. in some cases contraction is confined to one foot, while in others it may be noticed equally bad in both. it is a matter of common knowledge that contraction is usually seen in the fore-feet, while the hind seldom or never suffer from it, a fact which, to our minds, seems difficult of adequate explanation. zundel explains this by stating that contraction is principally _observed_ in the fore-feet, by reason of the fact that when lameness arises from it alteration in action will more readily be detected in front than behind. percival, on the other hand, suggests that the greater expansive powers of the hind-foot, by reason of the impetus of its action, is able to overcome any influence operating towards contraction. it may be, however, that given a cause for contraction, such as the removal of the frog's counter-pressure with the ground by faulty shoeing or excessive paring, the fore-feet, by reason of their being called upon to bear the greater part of the body-weight, are the first to suffer. flat feet with weak heels are those most frequently affected, and, as we have already intimated, the condition may exist with or without other disease of the foot. depending upon its degree, contracted foot may vary from a simple abnormality, non-inflammatory and painless, to a condition in which it becomes a veritable disease, giving rise to a bad form of lameness, and bringing about a withered and sometimes discharging and cankerous affection of the frog. _symptoms_.--in its early stages contraction is difficult of detection, and where both feet are affected may for some time go unsuspected. with only one foot undergoing change, the early stages may the more readily be marked, for in this case comparison with the other and sound foot will at once reveal the alteration in shape. if lameness in the suspected foot is present, then any lingering doubt will be quickly dispelled. when far advanced, contraction offers signs that cannot well be missed. the converging of the heels narrows the v-shaped indentation in the sole for the reception of the frog. as a consequence of this, the frog itself becomes atrophied by reason of the _continual_ pressure exerted upon it by the ingrowing horn of the wall and the bars. the median and lateral lacunæ of this organ, from being fairly broad and open channels, become pressed into mere crack-like openings (see the commencing of this condition in fig. 80, and a badly wasted frog in fig. 74a). as the case goes on, the lateral branches of the frog entirely disappear, and all that is left of the organ is a remnant of its body or cushion, now wedged in tightly between the bars. following upon the disappearance of the frog, we find that the bars are in contact, or, in some cases, actually overlapping each other at their posterior extremities. at this stage, perhaps, the whole condition has become aggravated by a foul discharge from the place originally occupied by the frog, and the foot, especially in the region of the heels, has become hot and tender--really a form of local and subacute laminitis. the long-continued inflammation, although only of a low type, renders the horn of the hoof hard and dry, and only with difficulty will the ordinary foot instruments cut it. this in its turn leads to cracks and fissures in various places, but more especially in the bars and what is left of the frog. often, too, cracks will appear in the horn of the quarters, and a troublesome and incurable form of sand-crack results. an animal with contraction advanced as far as this, especially if confined to one foot, goes unmistakably lame. with both feet affected, he ordinarily starts out from the stable in a manner that is commonly called 'groggy.' in other words, the gait is uncertain, and feeling; and stumbling is frequent. anyone who has had the misfortune to drive an animal with feet in this condition knows full well that every little irregularity in the road at once makes itself felt to the feet, and that the animal, as time goes on, learns to carefully avoid any suspicious-looking group of stones he may see. to drive an animal like this is to keep one's self continually on tenter-hooks, for, sooner or later, the inevitable happens, and the animal comes down. up to now we have described the changes of form in the hoof as seen when the contracted foot is viewed from the solar surface. with those changes as evident as we have depicted them, there will be no difficulty in detecting the alterations in the form of the wall. in addition to a narrowing from side to side there will be noticed an abnormal straightness of the quarters, with a turning in, more or less sudden, of the heels. this effect is given in these cases by the smith maintaining the shoe of a length and width that should normally fit a foot of that particular animal's size and substance. this is probably done with the idea of deceiving anyone examining the solar surface. viewed from this position, the width of the shoe at the heels gives the impression that it is attached to a foot of normal breadth. this deception is heightened if at the same time has been practised the process of 'opening up the heels.' that expression indicates that the bars have been removed, and the lateral lacunæ of the frog made to continue the concavity of the sole. the arch of the latter is thus made to appear of much greater extent than it really is, and the heels, by reason of their being abruptly cut off when removing the bars, also convey the false impression of being wide apart. the practitioner unversed in the tricks of the forge will best guard against this by viewing the foot, while on the ground, from behind. from that position he will be able to detect the lowness of the quarters, and the projecting portion of the shoe, that the hoof, by reason of its sudden bending inwards, does not touch. the 'feeling' manner of the gait before alluded to, together with the disinclination to put the foot firmly and squarely forward, will sometimes lead the examiner to over-look the contraction, and diagnose his case as one of shoulder lameness. in many cases, too, such consequent conditions as 'thrushy frogs' and 'suppurating corns' are often treated with utter disregard of the contraction that has really brought them about. but above all, the disease most likely to be confounded with simple contraction is navicular disease. more than probable it is that many cases of so-called 'navicular' have in reality been nothing more than contraction brought about by one or other of the causes we shall afterwards enumerate--cases where a due attention to the prime cause of the mischief would, in all likelihood, have remedied the lameness. _changes in the internal structures_.--it follows as a matter of course that the changes we have described in the form of the hoof itself carry with them alterations in the bones and sensitive structures beneath it. the tissues, as a whole, become atrophied. the os pedis becomes deformed, loses its circular shape, and gradually becomes more or less oval in contour. at the same time, its structure becomes more compact, the cribriform appearance of its anterior and lateral faces more or less destroyed, and the few remaining openings apparently increased in size. this atrophy of the os pedis is best noted at the wings. in the plantar cushion the effects of the atrophy are noted in the smallness of the organ, in its becoming whiter in colour than normal, and more resistant to pressure. the coronary cushion is also affected in the same way, where the changes are noted most in its posterior portions. a further effect of the narrowing of the heels, and their consequent tendency to drop downwards, is the exertion of a continual pressure on the sensitive sole. in course of time, and especially in flat feet, this leads to the appearance of corns. the navicular bone and bursa and the tendon of the perforans also suffer from the effects of compression. the movement of the tendon is restricted, and arterial supply to the adjacent structures rendered deficient. the tissues of the bone and bursa are insufficiently nourished, and the secretion of synovia lessened. in this way it is conceivable that navicular disease may follow the condition of simple contracted heels. in common with the other structures, the lateral cartilages also suffer from the continual pressure. their blood-supply is lessened, their functions interfered with, and side-bones result. _causes_.--upon the causation of contraction a very great deal has been written, both by early veterinarians and by those of the present day. many and widely differing opinions have been advanced, but a careful résumé of only a few will lead one to certain fixed conclusions. we may consider the causes of contraction under two headings--predisposing and exciting. _predisposing causes of contraction_.--among these we will first mention heredity, although it is possible it should not be deemed of so great account as it is by some. that the shape of certain feet, especially those with low heels and abnormally sloping walls, predisposes to contraction no one will deny. so long, however, as the animal goes unshod, so long does the foot maintain a normal condition of the heels. in other words, it is not until the tendency to contraction already there is aggravated by careless shoeing and the effects of work that it operates to any noticeable extent. the degree of contraction will also be very largely governed by the amount of the development of the frog. with a frog of good size, low down, and taking part in the pressure of the foot on the ground, contraction will be prevented. on the other hand, an ill-developed frog, one wasted by long-continued and spreading thrush, or one robbed of its normal function by excessive paring in the forge, is a common starting-point of the condition we are considering. we have already referred to this in chapter iii., when considering the experiments of lungwitz in this connection. what we have to bear in mind in these experiments is that the application of a pad to the frog, in such a manner that effective ground-pressure is obtained, results always in a marked expansion of the heels, and that, with counter-pressure with the ground absent, expansion occurs to little or no extent. this is proof positive of the enormous part the frog plays in maintaining an open and elastic condition of the heels--a fact so insisted on by coleman. it is worthy of mention, however, that loss of the frog's function does not operate to nearly so serious an extent in horses with high, upright heels as in those with the heels low and excessively sloping. in illustrating this, mr. dollar, in his work on shoeing, mentions the case of a pair of trotting horses of similar age, size, and weight, each having weak fore-heels. in one case the hoofs were flat, in the other upright. the horse with the flat hoofs suffered from contraction, while the other did not. the reason appears to be that in the animal with upright hoofs the proportion of body-weight borne by the heels is considerably less than in those with the hoofs flat and sloping. certain conditions of the horn-producing membranes also predispose to contraction. for example, in horses reared on marshy soils, and afterwards transferred to standing in town stables, we find that a dry and brittle condition of the horn supervenes. this we may regard as a low form of laminitis, brought about by the heat of the material upon which the animal is standing, and the congestion of the feet engendered by his enforced standing for long periods in one position, as opposed to the more or less continuous exercise when at pasture. with the hoof in this condition it loses by evaporation the moisture that normally it should contain, and, as we might expect, a certain degree of contraction of its structure is the inevitable result. we thus see that contraction brought about in this way is not so much caused by the heat of the stable, as it is by the decreased ability of the horn to retain its own moisture. on the other hand, it cannot be denied that excessive warmth and dryness combined tend also to an undue abstraction of moisture, even from the horn of the healthy foot; and this explains in great measure how it is that lameness, as a rule, and especially that proceeding from contracted heels, is far more frequent and of greater intensity in the hot, dry months of summer, than in the cooler and more humid atmosphere of winter. it is interesting to note, too, that an alternation of humidity and dryness is far more liable to injure the quality of the horn and tend to its contraction than the long-continued effects of dryness alone. a common illustration of this is to be found in the effects of the ordinary poultice. everyone knows that when, after a few days' application, they are discontinued, we get as a result an abnormally dry and brittle state of the horn. this is doubtless due to the poultice removing the thin, varnish-like, and protective pellicle known as the periople, and thereby allowing the process of evaporation to act on the water normally contained in the hoof. _exciting causes of contraction_.--among these, first place must undoubtedly be given to shoeing. this does not necessarily imply shoeing more than ordinarily faulty, nor a faulty preparation of the foot, but shoeing as it is generally practised. no ordinary shoe, except a few devised for the purpose, such as the charlier or the tip, allows the frog to come in contact with the ground. this we take to be the main factor in the causation of contracted heels, especially with a predisposition already present in the foot itself. in the words of lungwitz: 'regarded from this point of view, there is no greater evil than shoeing. it abolishes the necessary counter-pressure, and thus interferes with expansion. bars, sole, and frog cannot perform the functions that naturally belong to them as they would do without the shoe.' in addition to the evil of the shoe itself, errors of practice in the forge contribute to the causation of contraction. taking first the preparation of the foot, we find that often the heels are lowered far too much, and the toe allowed to remain too long. this can have but one effect--that of throwing a greater proportion of the animal's weight upon the heels than properly they should bear, with, what we now know to be the consequence of that, a corresponding pushing inwards and downwards of the horn; in other words, contraction. excessive paring of the bars, to which we have already partly alluded, is also an active agent in bringing about an inward growth of the horn of the heels and quarters. the bar, or inflexion of the wall at the heel, by means of its close contact with the frog, communicates the outward movements of that organ to the wall of the hoof. with the bar removed, the outward movements of the frog under pressure are naturally rendered of no account, and a proper and intermittent expansion of the wall denied it. the same evil follows, though to a less extent, excessive paring of the sole. the shape of the bearing surface of the shoe is often to be blamed. where this is concave--'seated'--and the 'seating' is carried back to the heels, it is easy to see that, when weight is on the foot, there is an ever-present tendency for the bearing edge of the wall to slide down towards the inner edge of the shoe. this tendency, operating on both the inner and outer wall simultaneously, must strongly favour contraction. a further wrong practice is that of continuing the nailing too far towards the heels. in our opinion this is not now often met with. when it occurs its effect is, of course, to prevent those movements of expansion of the wall which we now know to be normal and most marked at the heels. it may be remarked of the build of the shoe, or of errors in the preparation of the foot, that neither are of much moment. neither are they. but when one stays to consider that errors of this description are practised not only once, but each time the horse goes to the forge, and that with some of them--those relating to the build of the shoe--the injury thereby brought about is inflicted not only once, but every day that particular shoe is worn, then it is not to be wondered at that, sooner or later, ill consequences more or less grave result. _prognosis_.--this will depend to a very large extent upon the conformation of the limb, and upon the previous duration of the contraction. contraction of long standing, where atrophy of the sub-lying, soft structures and the pedal bone may be expected, will prove obstinate to treatment. especially will this be so if the lateral cartilages have become ossified. neither may we look for much benefit from treatment if the contraction has occurred in animals with an oblique foot axis and flat hoofs. on the other hand, if the case is comparatively recent, if the limb is straight and the form of the hoof is upright, and if matters are uncomplicated by side-bones, or other serious alteration in the internal structures, then treatment may be rewarded with some measure of success. [illustration: fig. 63.--tip shoe. the dotted portions represent the length of the branches removed.] _treatment_.--the greater part of the treatment of contracted foot will almost suggest itself as a corollary of the causes we have enumerated. the normal width of the heels may be renewed, and development of the wasted frog brought about by one of three methods: 1. by restoring the pressure from below to the frog. 2. by the use of an expansion shoe. 3. by operative measures upon the horn of the wall. 1. _by restoring the pressure from below to the frog_. this may be accomplished as follows: _(a) by shoeing with tips_.--this method is advocated by percival, by a.a. holcombe, d.v.s., inspector. bureau of animal industry, u.s.a., by dollar in his work on horseshoeing, and by many others. though requiring more care than in fitting the ordinary shoe, the application of a tip is simple. in reality, the tip is just an ordinary shoe shortened by truncating the heels. before applying the tip, the horn of the wall at the toe should be shortened sufficiently to prevent any undue obliquity of the hoof, and the foot should be so prepared as to allow the heels of the tip to sink flush with the bearing edge of the wall behind it. when the foot does not allow of the removal of much horn at the toe, what is termed a 'thinned' tip is to be preferred. its shape is sufficiently shown by the accompanying figure (fig. 65). with the tip the posterior half of the foot is allowed to come into contact with the ground, and the object we are striving for--namely, frog pressure, and greater facilities for alternate expansion and contraction of the heels--is thus brought about. [illustration: fig. 64.--the tip shoe 'let in the foot.] [illustration: fig. 65.--the thinned tip.] _(b) by shoeing with the charlier_.--the results brought about by the use of a tip may be arrived at by the application of a charlier or preplantar shoe, or by a modified charlier or charlier tip. briefly described, a charlier is a shoe that allows the sole and the frog to come to the ground exactly as in the unshod foot. this is accomplished by running a groove round the inferior edge of the hoof by removing a portion of the bearing edge of the wall with a specially devised drawing-knife. into this groove is fitted a narrow and somewhat deep shoe, made, preferably, of a mixture of iron and steel, and forged in such a manner that its front or outer surface follows the outer slope of the wall. the charlier should have the inner edge of its upper surface very slightly bevelled, in order to prevent any pressure on the sensitive sole, and should be provided with from four to six nail-holes. these latter should be small in size and conical in shape. the nails themselves should be small, and have a conical head and neck, to fit into the nail-hole of the shoe. [illustration: fig. 66.--the special drawing-knife (fleming's) for preparing the foot for the charlier shoe.] the modified charlier, or charlier tip, perhaps the better of the two for the purpose we are describing, is really a shortened charlier, and bears the same relation to the charlier proper as the tip does to the ordinary shoe. it is let into the solar surface of the foot in exactly the same manner as its larger fellow, but it does not extend backwards beyond the commencement of the quarters. by its use greater opportunity for expansion is given to the heels than is done by the charlier with heels of full length. [illustration: fig. 67.--foot prepared for the charlier shoe.] we do not here intend to deal at any length with the arguments for and against the charlier as regards its adoption for general use. these will be found fully set out in any good work on shoeing. the point that it is correct in theory it would be idle to attempt to evade; but that it is generally practicable, or that it offers any very pronounced advantages, as compared with the disadvantages urged against it, over the shoes in ordinary use, the limited favour it has drawn to itself, since its introduction in 1865, seems sufficiently to deny. _(c) by the use of a bar shoe_.--where the frog is not excessively wasted benefit will be derived from the use of a bar shoe. [illustration: fig. 68.--bar shoe.] the transverse portion at the back, termed the 'bar,' and which gives the shoe its name, is instrumental in bringing about from below that counter-pressure on the frog that we now know to be so necessary a factor in remedying contraction. when the frog, by wasting or disease, is so deficient as to be unable to reach the 'bar,' this shoe must be supplemented by a leather or rubber sole. in the event of corn or sand-crack existing with the contraction, the shoe known as a 'three-quarter bar' is preferable (see fig. 103). the break here made in the contour of the shoe allows of dressing the corn, and, in the case of sand-crack, removes the bearing from that portion of the wall. _(d) by the use of a bar pad and a heelless or 'half' shoe_.--the bar pad consists of a shape of rubber composition firmly fixed to a leather foundation, which shape of rubber takes the place of the 'bar' of the bar shoe. [illustration: fig. 69.--rubber bar pad on leather.] [illustration: fig. 70.--the bar, pad applied with a half-shoe.] for habitual use in such cases as prove obstinate to treatment, or where a complete cure was never from the commencement expected, the bar pad is undoubtedly one of the most useful inventions to our hand. the animal's 'going' is improved, the tender frog is protected from injury by loose stones, and greater comfort given to both the horse and the driver. [illustration: fig. 71.--frog pad.] [illustration: fig. 72.--frog pad applied.] _(e) by the use of a frog pad and a shoe of ordinary shape_.--the shape of rubber on this pad is designed to cover the frog only. its shape and mode of application is sufficiently shown in the accompanying illustrations. _(f) by turning out to grass_.--where the expense of keep is no object, a return of contracted feet to the normal may be brought about by removing the shoes and turning the animal out to pasture, thus giving the feet the advantages to be derived from a more or less continuous operation of the normal movements of expansion and contraction. in this case the treatment must extend from three to four, or possibly six months. 2. _by the use of some form of expansion shoe_. [illustration: fig. 73.--smith's expansion shoe seen from its ground surface and from the side. _a_, the screw, with a fine-cut thread; _b_, nut which travels along it; _c_, a hollow thimble into which the screw passes at one end, the other being cut out v-shaped to catch into a slot (_d_) on the shoe; _e, e_, the grip[a] for the bars, the length and direction of which depend upon the shape of the foot; _f, f_, the counter-sunk rivets forming the hinge (_f_'); _g_, the counter-sunk rivet of the expanding piece.] [footnote a: the inventor of this shoe uses the word 'grip' to denote what, in describing other expansion shoes, we term the 'clip' (h.c.r.).] _(a) smith's_.--for many years past continental writers have been practising this method. so far as we know, however, lieutenant-colonel fred smith was the first english veterinarian to use a shoe of his own devising, and to report on its effects. this shoe we will, therefore, give first mention. the above figure, with its accompanying letterpress, sufficiently explains the nature of the shoe. in fitting the shoe, care must be taken to have the hinges (_f, f_) far enough back, or the shoe will have a tendency to spring at the heels, and the grips _(e, e)_, which catch on the bars, will have a difficulty in biting. this trouble will be avoided by having the hinges about 1-1/2 to 2 inches from the heels. after the shoe has been firmly nailed to the foot, the travelling nut _b_ is driven forward on the screw _a_ so as to cause the grips to just catch on the inside of the bars of the foot. according to the inventor, the amount of pressure to be exerted must be learned by experience, and he says: 'i screw up very gradually until i see the cleft of the frog just beginning to open. i now trot the horse up, and if he goes sound it is certain that the pressure i have exercised will not give rise to trouble. the animal is sent to work to assist in the expansion of the foot. on examining the shoe next day, the grip is found to be quite loose, the foot has enlarged, and the nut is turned once more until the grip on the bars is tightened, the horse being again trotted to ascertain that no injurious pressure is exerted. 'every day or two i repeat this process, making measurements in all cases before widening the heels. the increase in width of the foot which results is astonishing, 1/4 to 3/8 inch during the first week may be safely predicted, and in a month to six weeks it is impossible to recognise in the large healthy frog and wide heels, the shrivelled-up organ of a short time before.'[a] [footnote a: _journal of comparative pathology and therapeutics_, vol. v., p. 98.] it is pointed out by the writer of the above (and his observations, doubtless, apply to the use of all other expansion shoes in which the bars are gripped and forcibly expanded) that the whole secret of success lies in avoiding injurious pressure by exerting too great an expansion at one operation. after each manipulation of the expanding apparatus the horse should trot sound and the frog remain cool. should the foot become hot, and lameness supervene, then tension should at once be relaxed. _recorded cases of the use of the shoe_.--the inventor of the shoe relates two cases of contracted foot treated by these means in which the heels of one, after thirty-nine days' treatment, had increased in width to the extent of 1 inch, and the heels of the other, after twenty-four days', had enlarged 5/8 inch. of the first case he gives the drawings in fig. 74. a represents the foot before treatment; b the same foot after nine days' treatment, when the heels had widened 3/4 inch; and c the same foot at the end of the thirty-nine days' treatment, at which date the frog was an excellent-looking one, and the foot had increased an inch in width.[a] [footnote a: _journal of comparative pathology and therapeutics_, vol. v., p. 100] [illustration: fig. 74.--the changes in form of a contracted foot treated with smith's expansion shoe] in 1893, at a meeting of the midland counties veterinary medical association, the late mr. olver said he had applied this shoe to a valuable hunter that had gone so lame that he could scarcely put his foot to the ground. after a fortnight's application, and by the assistance of the double screw in the shoe, the heel was forced out. then the horse was put to work with the shoe on, and he had hunted the whole of the last season in a perfectly sound condition.[a] [footnote a: _veterinary record_, vol. vi., p. 143] f.d. mclaren, m.r.c.v.s., writes:[a] 'i resolved to try one of captain smith's shoes in a case where the hoof was badly contracted, and where the frog had entirely disappeared, there being also slight lameness. the roof rapidly expanded, and every other day the nut was moved on a bit to keep the cross-piece tight. i then had the cross-piece bent downwards a little _to prevent the nut pressing on the rapidly-growing frog_.[b] after another fortnight or so, i had a shoe made with clips resting against the inside of the bars,[c] and the next time he was shod these were also dispensed with. it is now a year ago since the animal recovered his frog, and he still has the largest frog in the stable, and the hoof shows no sign of contraction.' [footnote a: _ibid_., vol. vi., p. 183] [footnote b: the italics are mine (h.c.r.).] [footnote c: the expanding shoe itself was here evidently dispensed with, and an ordinary shoe with bar-clips used in its stead (h.c.r.).] _(b) de fay's_.--among other shoes of the expansion class may be mentioned that of de fay. like the preceding, it is a shoe with a flat bearing surface, and provided with bar-clips. it is, however, _un_ hinged. the requisite degree of periodic expansion is in this case arrived at by a forcible widening of the heels of the shoe, accomplished by bending the substance of which it is made, and for this purpose the instrument illustrated in fig. 75 is employed. the foot is first properly trimmed by levelling the heels and thinning the sole on each side of the frog. the shoe is then fixed by nails in the ordinary manner, taking care that the last nails come not too far back, and that the clips rest evenly and firmly on the inside of the bars. the dilator, hoof-spreader, or vice, as it is variously called, is then applied, its two jaws (_a_ and _b_) fitting against the inner edge of the shoe at the heels. careful note is taken of the width of the hoof as measured on the graduated scale (_e_, _e_), and the double screw (_g_, _h_) revolved by means of the wrench (k), until the opening of the jaws thus obtained registers an expansion of 1/12 to 1/8 inch. the dilatation is repeated at intervals of from eight to ten days, until, at the expiration of a month or six weeks, the amount of total expansion of the heels registers nearly an inch. that the method requires the greatest care may be gathered from the reports of continental writers. they state that frequently the pain and consequent lameness keep the patient confined to the stable for several days. numerous and but slightly differing forms of the dilator are on the market. as in principle they are all essentially the same, and are to be found illustrated in any reliable instrument catalogue, they need no description here. [illustration: fig. 75.--de fay's vice.] _(c) hartmann's_.--a further useful expansion shoe is that of hartmann's (fig. 76), in that it may be adapted for either unilateral or bilateral contraction. this shoe is also provided with bar-clips, and forcibly expanded at the heels by means of a dilator. the expansion is governed by saw-cuts through the inner margin of the shoe directed towards its outer margin, and running only partially through the inner half of the web (see fig. 76). according as the contraction is confined to the inner or outer heel, the saw-cuts, one or two in number, are placed to the inner or outer side of the toe-clip. when the contraction is bilateral, the saw-cuts, one or more in number, are placed on each side of the toe-clip. _(d) broué's_.--this is one of the forms of so-called 'slipper' shoes (see fig. 77). we have already indicated that the shape of the bearing surface of the ordinary shoe--by its 'seating' or sloping from outside to inside--is sometimes a cause of contraction. in the 'slipper' of broué this bearing is reversed, and the slope is from inside to outside. in the original form of this shoe the slope to the outside was continued completely round the shoe. experience taught that the strain this enforced upon the junction of the wall with the sole was injurious, and that the 'reversed seating,' if we may so term it, was best confined to the hinder portions of the shoe's branches. [illustration: fig. 76. this figure illustrates the principle of the hartmann expanding shoe. _a, a_, the clips to catch the inside of the bars; _b, c_, saw-cuts.] the amount of slope should not be excessive. if it is, too rapid and too forcible an expansion takes place, and pain and severe lameness results. dollar gives the requisite degree of incline by saying that the outer margin of the bearing surface of the shoe should be from 1/12 to 1/8 inch lower than the inner. in the case of the broué slipper, it is the animal's own weight that brings about the widening of the heels, the slope or outward incline of the slipper simply causing the inferior edge of the wall at the heels to spread itself outwards instead of sliding inwards on the bearing surface of the shoe. [illustration: fig. 77.--the slipper shoe of broué.] _(e) einsiedel's_.--like the 'slipper' of broué, the einsiedel shoe depends for its effects upon the slope of the bearing surface. it differs from the broué in being provided with a 'bar-clip.' this, in addition to gripping the bars like the bar-clips of other expanding shoes, also assists, under the body-weight, in expanding the heels by the pronounced slope given to its upper surface. the expanding force exerted by the body-weight falls thus, through the medium of the bar-clip, clip, _partly_ upon the bars, instead of, as in the broué, solely upon the wall. we say _partly_ advisedly, for, in addition to the slope upon the outer side of the bar-clips, the bearing surface of the heels of the shoe is _slightly_ sloped outwards also. the good office served by the bar-clip is the lessening of any tendency to strain upon the white line. [illustration: fig. 78.--the slipper and bar-clip shoe of einsiedel.] those we have described by no means exhaust the number of expansion shoes that have been devised. there are numerous others, many of which are composed of three-hinged portions, the two hindermost of which are gradually separated by a toothed arrangement of their inner margins and a travelling bar, the disadvantage of which is that it is liable to work loose. in the majority of this class of shoe the hinges are placed far forward, one on each side of the toe. they there become exposed to excessive wear. in fact, against the bulk of this form of shoe it may be urged that they cannot be worn by the animal at work, that they are expensive, difficult to make, and easily put out of order. 3. _by operations on the horn of the wall_. _(a) thinning the wall in the region of the quarters_.--this is best done by means of an ordinary farrier's rasp. the thinning should lessen gradually from the heel for 2-1/2 to 3 inches in a forward direction. that portion of the wall next to the coronary border, about 1/2 inch in breadth, should not be touched. at this point the thinning should commence, should be at its greatest, and lessen gradually downwards until at the inferior margin of the wall the normal thickness of horn is left. the animal is then shod with a bar shoe and the hoof bound with a bandage soaked in a mixture of tar and grease, in order to keep the thinned portion of the wall from cracking. in this condition the animal may remain at light labour. when possible, however, it is better to combine the thinning process thus described with turning out to grass. in this case the ordinary shoe is first removed, and the foot poulticed for twenty-four hours to render the horn soft. the foot is then prepared by slightly lowering the heels--leaving the frog untouched--and thinning the quarters in exactly the manner described above. after this is done, the animal is shod with an ordinary tip, a sharp cantharides blister applied to the coronet, and then turned out in a damp pasture. in this case the object of the tip is to throw the weight on to the heels and quarters. the thinned horn yields to the pressure thus applied, and a hoof with heels of a wider pattern commences to grow down from the coronet. two to three months' rest is necessary before the animal can again he put to work.[a] [footnote a: this is the treatment strongly advocated by a.a. holcombe, d.v.s., inspector, bureau of animal industry, u.s.a.] _(b) thinning the wall in the region of the toe_.--this is done with the idea that the tendency of the heels to expand under pressure of the body-weight is helped by the thinned portion at the toe allowing the heels to more readily open behind. seeing that in the case of toe sand-crack the converse is argued--that contraction of the heels readily takes place and forces the sand-crack wider open--it is doubtful whether this method is of any utility in treating contracted heels. _(c) grooving the wall vertically or horizontally, and shoeing with a bar shoe_.--marking the wall with a series of grooves, each running in a more or less vertical direction, was suggested to english veterinarians by smith's operation for side-bones. the manner of making the grooves, and the instruments necessary, will be found fully described in section c of chapter x. that the method is followed by satisfactory results the undermentioned case will show: 'a mare, which i have had in my possession since she was a foal, has always had contracted feet, which were also unnaturally small.... lately the mare has been going very "short," and at length her action was quite crippled. at times she was decidedly lame on the off fore-foot. at no time have i been able to detect any sign of structural disease. i thereupon concluded that the lameness was due to mechanical pressure on the sensitive structures, and i determined to try the effects of the above treatment. as this was my first experience of the process, i was careful to carry it out in all its details, as described by professor smith. after the bar shoes had been put on, the mare was very lame. i allowed her two days' rest, then commenced regular walking exercise, and she daily improved. after fourteen days there was no lameness, but still short action. i thereupon gave the mare another week's walking exercise, at the expiration of which i drove her a short turn of five miles, which she did quite well, and free from lameness. for three months i kept the saw-cuts open to the coronet, and continued the bar shoes, keeping the mare at exercise, and giving her occasionally a drive. she never liked the bar shoes, and i was glad when i could discontinue them, which i did in the fourth month. when shod with the usual shoes the complete success of the treatment was shown. i have now had her going with the ordinary shoes for the past two or three months, and the improvement in the shape of the feet is very marked; there is no lameness; the mare is free in movement, fast, and spirited, whereas previously she was quite the reverse, and almost unfit to drive.'[a] [footnote a: w.s. adams, m.r.c.v.s., _veterinary journal_, vol. xxx., p. 19.] this method, though but recently introduced to the english veterinary surgeon, is by no means new. according to zundel, it was recently made known on the continent by weber, but was previously known and mentioned by lagueriniere, brognier, and hurtrel d'arboval. when the grooving is in a horizontal direction, a single incision is sufficient. this is made 3/4 inch below the coronary margin of the wall, and parallel with it, extending from the point of the heel for 2 or 3 inches in a forward direction. as in the previous method, a bar shoe is applied, and the animal daily exercised. thus separated from the fixed and contracted portion of the wall below, the more elastic coronet under pressure of the body-weight commences to bulge. the bulging is of such an extent as to cause the new growing hoof from the top to considerably overhang the contracted portion below, and cure of the condition results from the newly-expanded wall above growing down in a normal direction. this consideration of contracted heels may be concluded by drawing attention to the advisability of always maintaining the horn of the wall in as soft and supple a condition as is natural by the application of suitable hoof dressings. a useful one for the purpose is that made with lard, to which has been added a small quantity of wax or turpentine. especially should a dressing like this be used when the hoof is inclined to be hard and brittle, and where tendency to contraction has already been noticed. the application of a hoof ointment is also particularly indicated where the foot is much exposed to dampness, where the animal is compelled to stand for long periods upon a dry bedding, or where the bedding is of a substance calculated to have a deleterious effect upon the horn. this, in conjunction with correct shoeing, will probably serve to avoid the necessity for more drastic measures at a later time. _(b)_ local or coronary contraction. _definition_.--contraction at the heels, confined to the horn immediately succeeding that occupied by the coronary cushion. really, the condition is but a somewhat arbitrary subdivision of contracted hoof, as we have just described it in general. for that reason we shall give it but very brief mention. _symptoms_.--in this case the horn of the heels, instead of running down in a straight line from the coronary margin to the bearing surface of the wall, presents a more or less distinct concavity (see fig. 79, _a_, _a_). as is the case with contraction considered as a whole, this deformity may affect one or both heels; and during its first appearance, which is after the first few shoeings, the animal may go distinctly lame. _causes_.--coronary contraction may occur in hoofs of normal shape immediately shoeing is commenced, and frog pressure with the ground removed. it is far more likely to ensue, however, if the hoof is flat, with the heels low, and the wall sloping. and with those predisposing circumstances it is that the horse goes lame, and not with the hoof of normal shape. seeing, then, that this condition is largely dependent upon the shape of the foot, we may, to some extent, regard it as hereditary. seeing further, however, that it only appears when shoeing is commenced, we may in a greater degree also regard it as acquired. the lesson, therefore, that this and other forms of contraction should teach us is the carefulness with which the shoeing should be superintended in a large stud, or in any case where the animal is of more than ordinary value. [illustration: fig. 79.--hoof with local or coronary contraction (as indicated at the points _a, a_).] the explanation of the restricted nature of this form of contraction is simple enough. we have only to refer to the lessons taught by the experiments of lungwitz, described in chapter iii., and the condition almost explains itself. we remember that, briefly, the coronary margin of the wall resembles a closed elastic ring, which yields and expands to local pressure, no matter how slight. we remember also that removal of the counter-pressure of the frog with the ground tended to contraction of the wall's solar edge when weight was applied. connect these two facts with the experience that this form of contraction more often than not occurs in hoofs with sloping heels, and we arrive at the following: 1. the excessive slope of the heels tends to throw a more than usual part of the body-weight upon the posterior portion of the coronary margin of the wall, with a consequent expansion of that part of the coronary margin implicated. 2. that the shoeing, in removing the counter-pressure of the frog with the ground, is at the same time tending to bring about contraction of the lower portions of the wall at the heels and quarters. 3. that this tendency to contraction will at first appear in the thinner portion of the area of wall named--namely, in that immediately below the bulging coronary margin. we thus get the appearance depicted in fig. 79--a contraction _(a, a)_ of the heels in the horn below the coronary margin, with the coronary margin itself bulging above, and a hoof of apparently normal width below. we say 'apparently' with a purpose, for, as actual measurements will show, the wall near the solar edge is really contracting, for reasons which we have just described connected with shoeing. its 'appearance' of normal width is accounted for thus: the contraction at _a, a_ is caused by the dragging inwards of the coronary cushion brought about by the sinking downwards of the plantar cushion, with which body it will be remembered the coronary cushion is continuous. with the constant dragging in and down of the coronary cushion there is given, to the horn-secreting papillæ, studding both the lower third of its outer face and its lowermost surface, a distinct 'cant' outwards. below the lowermost limit of the coronary cushion, then, by reason of the cant outwards of the coronary papillæ in the situations mentioned, the horn of the wall takes a more outward direction than normal, a fact which lessens in effect the contraction as a whole really going on. it is interesting, too, to note that by this outward cant of the wall below, and the bulging of the coronary margin above it, the contraction (_a, a_) is heightened in effect, and caused to appear greater than really it is. from what we have said it follows that contraction of the heels, excepting the extreme coronary margin, is existent generally, and not confined solely to _a, a_. we have, then, in this condition, as we indicated at the commencement, but a phase in the evolution of ordinary contracted heels, for, with the progress of the contraction already existing at _a, a_, and below those points, it is only fair to assume that with it falling in of the at present bulging coronary margin must sooner or later occur, that, though expanded when compared with the wall below it, it will be really contracted as compared with what it was once in that same foot. we may therefore conclude this section by remarking that factors tending to contraction of the heels in general are equally potent in the causation of contracted coronet alone. _treatment_.--exactly that described for contracted heels. bearing in mind that contracted coronary margin is but the onset of contracted heels, and that its first exciting cause is that of removal of the ground-pressure upon the frog, the most careful attention must be paid to the shoeing. the use of bar shoes, ordinary frog pads, or heelless shoes and bar pads, are especially indicated, together with abundant exercise. by these means the normal movements of expansion will be brought into play, and the condition quickly remedied. c. flat-foot. _definition_.--by this term is indicated a condition of the foot where the natural concavity of the sole is absent. _symptoms_.--in the flat-foot the inferior edge of the wall, the sole, and the frog, all lie more or less in the same plane. it is a condition observed far more frequently in fore than in hind limbs, and is seen in connection with low heels, more or less obliquity of the wall, and a tendency to contraction. the action of the animal with flat feet is heavy, a result partly of the build of the foot, and partly of the tenderness that soon comes on through the liability of the sole to constant bruising. [illustration: fig. 80. this figure represents the lower surface of a typical flat-foot. it illustrates, too, the commencement of a condition we referred to in section b of this chapter--namely, the compression of the frog by the ingrowing heels (b) and bars (a).] _causes_.--flat-foot is undoubtedly a congenital defect, and is seen commonly in horses of a heavy, lymphatic type, and especially in those bred and reared on low, marshy lands. it is thus a common condition of the fore-feet of the lincolnshire shire. as might be expected, a foot of this description is far more prone to suffer from the effects of shoeing than is the foot of normal shape, and regarded in this light shoeing may be looked upon as, if not an actual cause, certainly a means of aggravating the condition. directly the shoe--or at any rate the ordinary shoe--is applied, mischief commences. the frog is raised from the ground, and the whole of the weight thrown on to the wall. the heels, already weak and inclined to turn in, are unable to bear the strain. they _turn in_, and contraction commences. this 'turning in' of the heels is favoured by the undue obliquity of the wall. at the same time, the sole being archless, a certain amount of elasticity is lost. the weight is thrown more on to the heels, and the os pedis slightly descends, rendering the flatness of the sole even more marked than before. with the loss of elasticity of the sole concussion makes itself more felt. the animal is easily lamed, bruised sole becomes frequent, and corns sooner or later make their appearance. _treatment_.--flat-foot is incurable. all that can be done is to pay careful attention to the shoeing, and so prevent the condition from being aggravated. in trimming the foot the sole should not be touched; the frog, too, should be left alone, and the wall pared only so far as regards broken and jagged pieces. the most suitable shoe is one _moderately_ seated. if the seating is excessive, and bearing allowed only on the wall, there is a tendency for the wall to be pushed outwards, and for the sole to drop still further. on the other hand, if the seating is insufficient, or the web of the shoe too wide, and too great a bearing thus given to the sole, then we get, first, an undue pressure upon the last-named portion of the foot a bruise, and, finally, lameness. the correct bearing should take in the whole of the wall and the whole of the white line, and should _just impinge_ upon the sole. above all, the heels of the shoe should be of full length, otherwise, if the shoe is worn just a little too long, its heels are carried under the sole of the foot, and by pressure there produce a corn. if, with these precautions in shoeing flat-foot, tenderness still persists, a sole of leather or gutta-percha must be used with the shoe. d. pumiced-foot, dropped sole, or convex sole. _definition_.--this term is applied to the foot when the shape of the sole is comparable to the bottom of a saucer. when least marked it is really an aggravated form of flat-foot. _symptoms_.--in pumiced-foot the sole projects beyond the level of the wall. the obliquity of the latter is more marked than in the previous condition, and progression, to a large extent, takes place upon the heels. in addition to its deformity, the horn is greatly altered in quality, and, as the name 'pumice' indicates, is more or less porous in appearance, bulging, and brittle. _causes_.--as a general rule, it may be taken that pumiced-foot is a sequel of previous disease, although in its least pronounced form it may occur as the result of accidental or other causes, such as those described in the causation of flat-foot. occurring in its most marked form, there is no gainsaying the fact that pumiced-foot is a sequel of either acute or subacute laminitis. as we shall see when we come to study that disease, the dropping of the sole is brought about by distinct and easily-understood morbid processes affecting the sensitive structures. briefly, these morbid processes in laminitis may be described thus: the accumulated inflammatory exudate, and in some cases pus, weakens and destroys the union between the sensitive and insensitive laminæ. this separation, for reasons afterwards to be explained, is greatest in the region of the toe. the os pedis, loosened from its intimate attachment with the horny box, is dropped upon the sole, and the sole, unable to bear the weight, commences to bulge below. the altered character of the horn is accounted for by the inflammatory changes in the sensitive laminæ and the papillæ of the keratogenous membrane generally, for it follows as a matter of course that these tissues, themselves in a diseased condition, must naturally produce a horn of a greatly altered and inferior quality. when following the _subacute_ form of laminitis, the changes characterizing pumiced-foot are slow in making their appearance. the animal at first goes short, and the lameness thus indicated gradually becomes more severe, until the animal is no longer able to work. the feet become hot and dry, the hoof loses its circular form, and the growth of horn at the heels becomes excessive. at this stage the appearance of bulging at the sole begins to make itself seen. later, the outer surface of the wall becomes 'ringed' or 'ribbed,' the rings being somewhat closely approximated in the region of the toe, and the distance between them gradually widening towards the heels. the wall too, especially in the region of the toe, instead of running in a straight line from the coronary margin to the shoe, becomes concave. it is this change, together with the appearance of the rings, that indicates the loosening of the attachment of the os pedis to the wall, and its afterwards backward and downward direction (see fig. 124). [illustration: fig. 81.--hoof with the ribs or rings caused by chronic laminitis.] as a sequel of _acute_ laminitis, these changes make their appearance with more or less suddenness, and are generally complicated in that they owe their occurrence to the formation of pus within the horny box. _treatment_.--pumiced-foot is always a serious condition. the animal is useless for work upon hard roads or town pavings, and is of only limited utility for slow work upon soft lands. the more serious form, that following acute laminitis, and complicated by the presence of pus, we may regard as beyond hope of treatment. with the more simple form of the condition, we may do much to render greater the animal's usefulness. the same principles as were applied to the shoeing of flat feet will have to be observed here. trimming or paring of any kind, save 'straightening up' of the wall, must be severely discountenanced. a broad-webbed shoe, one that will give a certain amount of cover to the sole, is indicated. as in the treatment of flat-foot, however, direct pressure upon the sole must be avoided, and the shoe 'seated.' the 'seating,' however, should not commence from the absolute outer margin of the shoe's upper surface. a _flat_ bearing should be given to the wall and the white line, and the seating commenced at the sole. we have already remarked on the increased growth of horn at the heels. it is in this position, then, that will be found the greatest bearing surface for the shoe, and it is wise, in this case, to have the heels of the shoe kept flat. in other words, the 'seating' is not to be continued to the hindermost portion of the branches of the shoe. by this means there may be obtained at each heel a good solid bearing of from 2 to 3 inches, which would otherwise be lost. where the accompanying condition of the horn is bad enough to indicate it, a leather sole should be used, beneath which has been packed a compress of tow and grease, rendered more or less antiseptic by being mixed with tar. where the sole is exceedingly thin, and inclined to be easily wounded, and where the hoof, by its brittleness, has become chipped and ragged at the lower margin of the wall, it may perhaps be more advantageous to use, in place of the compress of tow, the _huflederkitt_ of rotten. this is a leather-like, dark brown paste. when warmed in hot water, or by itself, it becomes soft and plastic, and may readily be pressed to the lower surface of the foot, so as to fill in all little cracks and irregularities, and furnish a complete covering to the sole and frog, and to the bearing surface of the wall. when cold it hardens, without losing the shape given to it, into a hard, leather-like substance. treated in this way, the animal with pumiced feet may yet be capable of earning his living at light labour or upon a farm. e. 'ringed' or 'ribbed' hoof. _definition_.--a condition of the hoof in which the wall is marked by a series of well-defined ridges in the horn, each ridge running parallel with the coronary margin. they are known commonly as 'grass rings,' and may be easily distinguished from the more grave condition we have alluded to as following laminitis, by the mere fact that they do not, as do the laminitic rings, approximate each other in the region of the toe, but that they run round the foot, as we have already said, _parallel with each other_. [illustration: fig. 82.--hoof showing the rings in the horn brought about by physiological causes.] _causes_.--this condition is purely a physiological, and not a pathological one, and the words of its more common name, 'grass rings,' sufficiently indicate one of the most common causes. anything tending to an alternate increase and decrease in the secretion of horn from the coronet will bring it about. thus, in an animal at grass, with, according to the weather conditions, an alternate moistness and dryness of the pasture, with its consequent influence on the horn secretion, these rings nearly always appear. the effects of repeated blisters to the coronet make themselves apparent in the same way, and testify to the efficacy of blisters in this region in any case where an increased growth of horn is deemed necessary. from this it is clear that the condition depends primarily upon the amount and condition of the blood supplied to the coronary cushion. thus, fluctuations in temperature during a long-continued fever, or the effects of alternate heat and cold, or of healthy exercise alternated with comparative idleness, will each rib the foot in much the same manner. _treatment_.--the condition is so simple that we may almost regard it as normal. consequently, treatment of any kind is superfluous. where constitutional disturbance is exerting an influence upon either the quality or quantity of the blood directed to the part, then, of course, attention must be paid to the disease from which it is arising. f. the hoof with bad horn. (_a_) the brittle hoof. _definition_.--as the name indicates, we have in this condition an abnormally dry state of the horn. _symptoms_.--these are obvious. the horn is hard, and when cut by the farrier's tools gives the impression of being baked hard and stony, the natural polish of the external layer is wanting, and there is present, usually, a tendency to contracted heels. with the dryness is a liability to fracture, especially at points where the shoe is attached by the nails. as a consequence, the shoes are easily cast, leading to splits in the direction of the horn fibres. these run dangerously near the sensitive structures, giving rise in many cases to lameness. even where pronounced lameness is absent the action becomes short and 'groggy,' and the utmost care is required in the shoeing to keep the animal at work. _causes_.--to a very great extent the condition is hereditary, and is observed frequently in animals of the short, 'cobby' type. in ponies bred in the welsh and new forest droves the condition is not uncommon, especially in the smaller animals. animals who have had their feet much in water--as, for instance, those bred and reared on marshy soils--and afterwards transferred to the constant dryness of stable bedding, are also particularly liable to this condition. it is noticed, too, following the excessive use of unsuitable hoof-dressings, more especially in cases where coat after coat of the dressing is applied without occasionally removing the previous applications. _treatment_.--as a prophylactic, a good hoof-dressing is indicated. it should not consist solely of grease, but should have mixed with it either wax, turpentine, or tar. above all, careful shoeing should be insisted on, and the owner of an animal with feet such as these will be well advised if he is recommended to have the shoeing superintended by one well competent to direct it rightly. the foot should be trimmed but lightly, always remembering that in a foot of this description the horn, in addition to being brittle, is generally abnormally thin. jagged or partly broken pieces should be removed, and the bearing surface rendered as level as possible. the foot should be carefully examined before punching the nail-holes in the shoe, and the nail-holes afterwards placed so as to come opposite the soundest portions of horn. the nails themselves should be as thin as is consistent with durability, and should be driven as high up as possible. on the least sign of undue wear the shoes should be removed, never, as is too often done, allowing them to remain on so long that a portion breaks away. if, with the laudable idea of not interfering with the horn more than is possible, this is practised, the portion of the shoe breaking off is bound to tear away with it more or less of the brittle horn to which it is attached. where the breaks in the horn are so large as to prevent a level bearing for the shoe being obtained, the interstices should be filled up with one or other of the preparations made for this purpose. one of the most suitable is that discovered by m. defay. by its means sand-cracks or other fractures of the horn may be durably cemented up. 'even pieces of iron may be securely joined together by its means. the only precaution for its successful application is the careful removal of all grease by spirits of sal-ammoniac, sulphide of carbon, or ether. m. defay makes no secret of its composition, which is as follows: take 1 part of coarsely-powdered gum-ammoniac, and 2 parts of gutta-percha, in pieces the size of a hazel-nut. put them in a tin-lined vessel over a slow fire, and stir constantly until thoroughly mixed. before the thick, resinous mass gets cold mould it into sticks like sealing-wax. the cement will keep for years, and when required for use it is only necessary to cut off a sufficient quantity, and remelt it immediately before application. we have frequently used this cement for the repair of seriously broken hoofs. it is so tenacious that it will retain the nails by which the shoe is attached without tearing away from the hoof.'[a] [footnote a: _veterinary journal_, vol. iii., p.71.] failing this, the bearing surface may be made level, and fractures repaired by using the _huflederkitt_ described in the treatment of pumiced sole. (_b_) the spongy hoof. _definition_.--this is the opposite condition to the one we have just described, and is characterized by the soft and non-resistant qualities of the horn. _symptoms_.--spongy hoof is quite common in animals that have large, flat, and spreading feet--in fact, the two appear to run very much together. it is a common defect in animals reared in marshy districts, and of a heavy, lymphatic type. the lincolnshire shire, for instance, has often feet of this description, and, the causative factors being in this case long-continued, render the feet extremely predisposed to canker. the horn is distinctly soft to the knife, and has an appearance more or less greasy. animals with spongy feet are unfit for long journeys on hard roads. when compelled to travel thus, the feet become hot and tender, and lameness results. a mild form of laminitis, extending over a period of three or four days, often follows on this enforced travelling on a hard road, more especially in cases where the animal is 'heavy topped,' and the usual food of a highly stimulating nature. in fact, it has been the author's experience to meet with this condition several times in the case of shire stallions doing a long walk daily upon hard roads, with the weather hot and dry. _treatment_.--when a horse with spongy feet is shod for the first time, care must be taken to avoid excessive paring of the sole, for already the natural wear of the foot has been sufficient to keep the soft horn in a state of thinness. for the same reason hot fitting of the shoe must not be indulged in for too long a time. that common malpractice of the forge, 'opening up the heels,' must, in this case, be especially guarded against, or the excessive paring of the frog and partial removal of the bars that this operation consists in will lay the foot open to risk of contraction. to begin with, the heels are naturally weak, and, once the bars are removed, there is nothing to prevent them rapidly caving in towards the frog. even when carefully shod, a foot of this class is readily prone to contract directly the animal is brought into the stable, and the horn commences to dry to excess. an ordinary light shoe should be used, and the nails should be light and thin. they should be driven carefully home, and the 'clinching' made as tight and secure as possible. g. club-foot. _definition_.--under this name we indicate all cases in which the horn of the wall become straightened from above to below. it will, therefore, include all conformations varying from the so-called 'upright hoof,' in which the toe forms an angle of more than 60 degrees with the ground, to the badly 'clubbed' foot, in which the horn at the toe forms a right angle with the ground, or is even directed obliquely backwards and downwards, so that the coronary margin overhangs the solar edge of the wall. [illustration: fig. 83.--the club-foot.] _symptoms_.--even in its least pronounced form the condition is apparent at a glance, the alteration in the angle formed by the hoof with the ground striking the eye at once, and the heels, as compared with the toe, appearing much too high. when the condition is slight, the wall of the toe is about twice as high as that of the heels, while in the most marked form the toe and the heels may in height be nearly equal (see fig. 83). when congenital, but little interference with the action is noticed. such animals, by reason of their 'stiltiness,' are unfit for the saddle, but at ordinary work will perform their duties equally well with the animal of normal-shaped feet. when acquired as the result of overwork, of contracted tendons, or other causes, however, the gait becomes stumbling and uncertain. the body-weight is transferred from the heels to the anterior parts of the foot, and the shoe shows undue signs of wear at the toe. _causes_.--upright hoof is undoubtedly hereditary, and is even seen as a natural conformation in the feet of asses and mules. when hereditary in the horse, however, it is certainly a defect, and is associated commonly with an upright limb, and a short, upright pastern (see fig. 83). among other causes, we may enumerate sprains or wounds of the flexor tendons, or any disease of the limbs for a long time preventing extension of the fetlock-joint, such as sprains or injuries of the posterior ligaments of the limb, splints or ringbones so placed as to interfere with the movements of the flexor tendons, or, in the hind-limb, spavin, keeping for some months the fetlock in a state of flexion. in the very young animal the condition may be induced by an improper paring of the foot--cutting away too much at the toe, and allowing the heels to remain. _treatment_.--when the condition is congenital, no treatment at all is indicated. it might, in fact, be said that interference would tend rather to minimize than enhance the animal's usefulness; for, in this case, the club-shaped feet are in all probability due to faulty conformation above. in other words, the upright hoof is in this instance but a natural result of the animal's build, with which useful interference is impossible. where the upright hoof is a consequence of excessive paring of the toe, or insufficient removal of the heels, the condition may be remedied by directing attention to those particulars, and preventing their continuance. at the same time, a greater obliquity of the limb axis may be given by the use of a suitable shoe. the shoe indicated is a short one, with thin heels and a thick toe. in some cases the abnormality may be remedied by the use of a tip. whatever method is adopted, care must be taken not to attempt too positive a change in the direction of the limb at one operation. the process must be gradual. in cases where the abnormality has been brought about by wounds to the flexor tendons, the alteration in the direction of the limb is often so great as to produce 'knuckling over' of the fetlock. this, to a very great extent, may be remedied by the use of a shoe with calkins and an extended toe-piece (see fig. 84). [illustration: fig. 84.--the shoe with extended toe-piece and high calkins.] with this shoe a certain amount of forced exercise is advisable, and at intervals of about two weeks the calkins should be somewhat lowered, until the heels are brought as close to the ground as is possible. in giving directions for this shoe to be made the veterinary surgeon must, when referring to the length of the toe-piece, be guided entirely by the condition of the case. ordinarily, a suitable length is from 3 to 4 inches. it is necessary also to warn the owner that, by reason of the length projecting, the shoe is liable to be torn off. should the 'knuckling over' have become complicated by bony deposits round the seat of the original injury, then a favourable modification of the condition is not so likely to result. the benefit to be derived from the shoe with an extended toe-piece in a case of excessive knuckling is admirably shown in a brief report of a case, under the title of 'hooked foot,' in vol. xiv. of the _veterinary record_, p. 716: 'an eighteen months' old filly showed a deformity of the third phalanx, resulting in her walking with the front face of the hoof on the ground. the flexors were apparently all right, and the bending back seemed to be due to contraction of the ligaments of the joint and the sheath of the perforans. 'on the ground of absence of contraction of the flexors, or atrophy and paralysis of the extensors, the surgeon considered the lesion curable by simple orthopædic measures. by means of an elongated toe-piece to the shoe and calkins, which were shortened every fifteen days, the filly was completely cured in seventy days.' h. the crooked foot. (_a_) the foot with unequal sides. _definition_.--the foot thus affected has one side of the wall higher than the other. _symptoms_.--this deformity is the better recognised when the foot on the floor is viewed from behind. in addition to the difference between the height of the inner and outer heel is seen at once a deviation in the normal direction of the horn. that of the higher side is distinctly more upright than that of the lower, and runs from above downwards and inwards towards the axis of the foot, while the horn of the lower side maintains its normal direction of downwards and outwards. from what we have said before on contracted foot, this bending in of the wall of the upright side will at once be recognised as a form of contraction. it is, in fact, contraction confined to one-half of the foot only, and, as a result, the upright side of the crooked foot is prone to the troubles arising from that condition. corns are frequent, and atrophy of that half of the frog on the affected side supervenes. with the inflammatory changes accompanying these conditions we find the horn of the affected side deteriorating in quality. it becomes dry and brittle, and extremely liable to sand-crack. at the same time, thrush of the contracted frog begins to make its appearance. _causes_.--more often than not this condition is a result of the conformation of the limb. according as the build above inclines the animal to 'turned in' or 'turned out' toes, so shall we have feet with a wall crooked inwards or crooked outwards; and it may be mentioned here that the evil results inflicted on the foot by ill-shaped limbs above will make themselves the more readily noticed when the animal comes to be shod for any length of time. so long as a natural wear of the foot is allowed, so long does it accommodate itself to the form of limb above. so soon, however, as the shoe is applied, and a more or less equal (and in this case harmful) wear by that means insisted on, so soon does this abnormal change in the height and direction of the horn fibres begin to make itself seen. while arising in the majority of instances from faulty conformation of the limb, crooked feet may also be brought about by bad shoeing, or by unequal paring of the foot, and, in a few cases, from unequal wear of the foot in a state of nature. _treatment_.--although it may be taken as a rule that lowering of the higher wall, even if persisted in at every shoeing, will do nothing towards remedying the primary cause (viz., the evil conformation of the limb), yet it will serve to keep the condition within reasonable limits. in this case, while removing so much of the wall as is deemed necessary, care must be taken to leave uncut the sole and the bar. leaving these intact gives us two natural and very potent protections against the contraction already mentioned as impending. where, by reason of the thinness of the horn or other causes, sufficient paring to equalize the tread cannot be practised, then the same end may be arrived at by the use of special shoes. that branch of the shoe applied to the half of the foot with the lower wall should be thickened from above downwards. or, on the same branch, may be turned up a calkin of sufficient height for the purpose. of the two methods the first is preferable. in any case, whether depending upon paring, or upon the use of a special shoe, the animal should be sent to the forge quite often, for it is only by a well-directed, and therefore constant, application of the principles here laid down that improvement may be brought about. when marked contraction of one-half of the foot is present, it will be best treated with the expanding shoe of hartmann, already described in the section of this chapter dealing with contracted heels (see fig. 76). (_b_) the curved hoof. _definition_.--the hoof with the wall of one side convex, and that of the opposite side concave. fig. 85, showing the foot in section from side to side, gives an exact idea of this malformation. _causes_.--as was the case with the condition previously described, this abnormality finds its primary cause in an unequal distribution of weight due to vice of conformation in the limb above, causing one side of the hoof to be higher than the other. as a result of this, the wall that is inordinately increasing in height commences to bulge outwardly (fig. 85, _a_), while the opposite (fig. 85, _b_) becomes concave. the same state of affairs may be occasioned in the forge by leaving one side of the foot too high, and subjecting the other to excessive paring for several consecutive shoeings. _treatment_.--in the main this condition may be regarded as a long-standing and aggravated form of the foot with unequal sides. we may say at once, therefore, that it is not so easily remedied as that simpler defect; that, although identical principles will be followed in its treatment, cure must be a matter of some considerable time. [illustration: fig. 85.--section through a crooked foot. _a_, the higher and convex side of the wall; _b_, the lower and concave side of the wall] again, we must look to successive parings of the wall of the higher side to bring about a gradual return to the normal. at the same time, the tendency to contraction of that side is counteracted by shoeing wide, and, if necessary, giving to the upper surface of that branch of the shoe what we have termed elsewhere a 'reversed seating'--viz., an incline of its upper surface from within outwards. chapter vii diseases arising from faulty conformation a. sand-crack. _definition_.--a solution of continuity of the horn of the foot, occurring usually in the wall, and following the direction of the horn fibres. _classification_.--it is usual to classify sand-cracks according to-_(a) their position_.--_toe-crack_ when occurring in the middle line of the horn of the toe, and _quarter-crack_ when occurring in the horn of the quarters. sand-crack of the frog and sand-crack of the sole may also each be met with. they are, however, of rare occurrence, and are seldom serious enough to merit special attention. the toe-crack is met with more often in the hind-foot than in the fore, while the quarter-crack more often than not makes its appearance in the fore-foot, and is there, as a rule, confined to the inner side. the reasons for these positions being so affected we shall deal with when treating of the causes of sand-crack in general. it is interesting to note that the portions of wall known as inside and outside toe are seldom affected. _(b) their length_.--_complete_ when they extend from the coronary margin of the wall to its wearing edge; _incomplete_ when not so extensive. _(c) their severity_.--_simple_ when they occur in the horn only, and do not implicate the sensitive structures beneath; _complicated_ when deep enough to allow of laceration and subsequent inflammation of the keratogenous membrane. such complications may vary from a simple inflammation set up by laceration and irritation of the sensitive structures by particles of dirt and grit that have gained entrance through the crack, to other and more serious changes in the shape of the formation of pus, hæmorrhage from the laminal vessels, caries of the os pedis, or the development of a tumour-like growth of horn on the inner surface of the wall known as a keraphyllocele. _(d) their duration_.--_recent_ when newly formed; _old_ when of long standing. _(e) their starting-point_.--this last distinction we make ourselves, and, referring to cracks of the wall, term them _high_ when commencing from the coronary margin, _low_ when starting from the bearing surface. _causes_.--we have already classified sand-crack as a disease arising from faulty conformation. thus, in just so far as a predisposing build of body may be handed down from parent to offspring, we may regard sand-crack as hereditary. if we do so, however, we must afterwards make up our minds to sharply distinguish between the sand-crack plainly brought about by accidental cause, and that occurring as a result of hereditary evil conformation. with regard to the latter, we need hardly say that feet with abnormally brittle horn are extremely liable. but with this, as with many other affections of the feet, we shall find it necessary to consider several causes acting in cooperation. in this case, for instance, given the brittle horn, it becomes necessary to further look for exciting causes of its fracture. we will take conformation first. in the animal with turned-out toes a more than fair share of the body-weight is imposed on the horn of the inner quarter. here, then, three causes exert their influence together: the horn is brittle; the wall of the inner quarter is thinner than that of the outer; additional weight is imposed upon it. fracture results. take, again, the vice of contracted heels. here, in the first place, we have a variety of causes tending to bring about the contraction. with the contraction, and its consequent pressure upon the sensitive structures in the region of the quarters and the frog, has arisen a low type of inflammation. the horn of the part has become dry and brittle. the exciting cause of its fracture is found in an excessive day's work upon a hard, dry road, with, perhaps, a suddenly-imposed improper distribution of weight, due to treading upon a loose stone, or a succession of such evil transfers of weight due to travelling upon a road that is rough in its whole extent. in their turn, too, such defects of the feet as we have mentioned in the last chapter--as, for example, the foot with the pumiced horn, the foot with abnormally upright heels, or that which is upright on one side only, or crooked--each offers a condition which is predisposing to the formation of a sand-crack. in each case it wants but the uneven distribution of the body-weight, which, as a matter of fact, some of these conditions themselves give, to bring about a fracture. apart from the predisposition conferred by conformation, must be remembered the simpler predisposing causes leading to brittleness of the hoof. we refer to the after-effects of poulticing, the moving from pasture to stable, the emigration from a damp to a dry climate, or the alternate changes from damp to dry in a temperate region. each may have a deteriorating influence upon the horn, rendering it liable to the condition we are describing. excessive dampness alone, especially when the animal is called upon to labour at the drawing of heavy loads upon a rough road, is not infrequently a cause. in this case the wet, together with the constant friction of the sharp materials of which the road is made, serves to destroy the varnish-like periople. the wet gains access to the inner structures of the wall, the agglutination of the horn fibres is weakened, and fissures begin to appear. other causes of sand-crack are purely accidental. an animal at fast work over-reaches. the secretion of horn at the injured coronet is interfered with, a diminished supply at an isolated spot being the result. from this point grows down a fissure in the wall. an injury of the same character may also be sustained in various other ways--treads from other animals when working in pairs, accidental wounding with the stable-fork, blows of any kind, or a self-inflicted tread with the calkin of an opposite foot--each with the same result. so far as causation is concerned, toe-crack stands in a class almost by itself. it is met with nearly always in a heavy animal in the hind-foot, and is directly attributable to the force exerted in starting a heavy load. unskilful shoeing also plays a part in the causation of sand-crack. removal of the periople by excessive rasping of the wall is most certainly a predisposing cause. cracks, or their starting-points, may also be caused by using too wide a shoe, or by the use of nails too large in the shank. also, they may arise from unskilful fitting of the toe-clip, especially in the hind-foot of a heavy animal. it must be admitted, however, that the part shoeing plays in the causation of sand-crack is not a large one; far more depends upon the state of the horn and the animal's conformation than upon the exciting cause. so far, our observations on the causes of sand-crack have referred to that form occurring in the wall. sand-crack of the sole or frog we have already said is but seldom met with, and then it is always in connection with some exceptionally deteriorated quality of the horn, as in the case of badly pumiced feet, or occurs as a result of direct injury. extensive slit-like cuts in this region, when deep enough to lacerate the keratogenous membrane, are sometimes followed by the growth of a fissure in the horn, and what might almost be termed a permanent sand-crack results. such cuts may be occasioned by sharp flints, broken glass, or other sharp objects picked up on the road, or may result from the animal treading on the toe-clip of a partially cast shoe. _symptoms_.--in every case the fissure, or evidence of its commencement, is a diagnostic symptom. it is well to remember, however, that this may be easily overlooked, especially when the crack is one commencing at the coronary margin. the reason is this: sand-cracks in this position often commence in the wall proper, and not in the periople. they may, in fact, be first observed as a fine separation of the horn fibres immediately beneath the perioplic covering. a crack of this description may even show hæmorrhage, and have been in existence for some time, without the periople itself showing any lesion whatever. thus, unless lameness is present, or a more than specially keen search is directed to the parts in question, the sand-crack goes undiscovered, until of greater dimensions. further, the fissure may be hidden, either accidentally or of set purpose. it may be covered by the hair, filled in and covered over with mud, or intentionally concealed by being 'stopped' with an artificial horn, with wax, or with gutta-percha, or, as is more common, be hidden by the lavish application of a greasy hoof-dressing. in this latter connection it is well to warn the veterinary surgeon, especially the beginner, when examining for soundness, to be keenly critical before passing an animal who is presented with feet smothered with tar and grease or any other dressing. more especially should this warning be heeded when examining any of the heavier breeds of animal with an abundance of hair about the coronet. referring again to the search for the crack, it is well to know that with toe-crack the fissure is the more readily seen when the foot is lifted from the ground. with quarter-crack, on the other hand, the fissure is wider, and consequently the easier detected with the foot bearing weight. although commencing in the insidious manner we have described, the lesion is not thus often seen by the veterinary surgeon. usually, the animal with sand-crack is brought for his inspection when lameness has arisen from it. in this case the cause for the lameness will reveal itself in the crack, which is now too large to escape observation. the coronet is hot and tender to the touch, and a sensation of warmth is sometimes conveyed to the hand by the horn of the surrounding parts of the wall. it is hardly necessary to say that, with accompanying conditions such as these, the sand-crack is a _deep_ one. where the lameness is but slight, we may attribute it almost solely to the pain occasioned by the mere wounding of the keratogenous membrane, and to no very extensive inflammatory changes therein. by some authorities this is said to be due to the pinching of the sensitive structures between the edges of the fissure in the horny covering. in our opinion, however, pinching does not occur unless inflammatory exudation into the sensitive structures adjoining the crack has led to sufficient swelling to cause them to protrude. in other words, the movements of the horny box, communicating themselves to the structures beneath, and so occasioning movement in the wounded keratogenous membrane, are quite sufficient to give rise to the lameness without actual pinching of the structures implicated. the severity of the lameness will vary with the rapidity of the gait, and with the character of the road upon which the animal is made to travel. for instance, many animals in which the lameness is imperceptible at a walk become 'dead' lame at a fast trot. it is sufficiently explained when one remembers the greater movements of expansion and contraction of the posterior parts of the wall brought about by the increase in the rate of progression. the same animal, too, will go distinctly more lame upon a hard than upon a soft surface. in like manner the lameness from toe-crack also varies in degree with the rate of progression and the character of the travelling, though not to such a noticeable extent as in the lameness from quarter-crack. a greater variation may in this case be brought about by moving the animal on ascending and descending ground. descending an incline, with a more than ordinary share of the body-weight thus thrown upon the heels, the lameness is most marked. the reason would appear to be that the greater expansion of the wall of the heels thus brought about leads to a proportionate contraction of the wall at the toe, especially at the edges of the crack, thus causing undue pressure upon the exact spot of the wound in the sensitive structures. ascending--the weight in this case transferred from the posterior to the anterior portion of the foot--the expansion of the heels becomes a contraction, with a corresponding lessening of the contraction at the toe and a distinct decrease in the lameness. in the case of a deep but recent crack there is always more or less hæmorrhage. this favours risk of infection of the lesion with pus-forming organisms, and so leads to a more or less pronounced lameness, a degree of swelling, heat and tenderness in the coronet above, and a certain amount of surgical fever. the acute symptoms subdued, but the fissure still remaining, gives us the crack we have classified as 'old.' this may in every case be distinguished from a more recent lesion by the amount of thickening of the overhanging coronet, and the presence of an increased quantity of sub-coronary horn in the region immediately about the crack. the previous inflammatory changes in the adjoining sensitive structures have here led to an increased secretion of horn, and a greater or less deposition of inflammatory connective tissue in the wounded coronary cushion. sand-crack of the toe always follows the direction of the horn fibres. that of the quarter, however, may on occasion run a course that is somewhat zigzag, first following the direction of the horn fibres for a short distance, then travelling in a horizontal direction, and finally continuing its course again in a line with the horn fibres, commonly at a point posterior to that at which it commenced. in a quarter-crack that is old, and when contraction of the heels exists (which in this case it usually does), then will often be found overlapping of the edges of the crack. the expansion of the wall brought about when the body-weight is on the heels, cannot, by reason of the break in it, continue itself anterior to the crack. as a consequence, repeated expansion of the wall posterior to the crack, with the portions anterior to it in a state of enforced quiescence, leads in time to the posterior edge of the crack coming to lie over that of the anterior. _complications_.--the first complication likely to arise in a case of sand-crack is that attending simple laceration of the sensitive structures in a _deep_ lesion. with the laceration all the phenomena of a repairing inflammation make their appearance. as a result, there is more or less heat according to the degree of inflammatory hyperæmia, swelling according to the amount of inflammatory exudate, and pain according to the amount of pressure the two foregoing bring to bear on the nerves in the inflamed area. a second and more serious complication is the greater inflammation set up by the introduction into the crack of foreign substances. small portions of gravel and flint, both by the irritation set up by their friction and by the infection they carry in with the dirt surrounding them, are responsible for the mischief. when, from direct communication with the blood-stream, due to extensive hæmorrhage, bacteria from the outside gain entrance, this simple inflammation is further complicated by the formation of pus, or a limited gangrene of the keratogenous membrane. in cases of great severity the gangrene of the keratogenous membrane spreads until the deeper structures are involved. we then get a necrosis (in the case of toe-crack) of the extensor pedis, and sometimes caries of the os pedis. in like manner the necrotic changes occurring under these circumstances may invade the deeper structures in the region of quarter-crack. as a result of this, we may have the starting-point of suppurating corn, or necrosis of the lateral cartilage--in other words, cartilaginous quittor. commonly accompanying quarter-crack is the condition of contracted heels and atrophied frog. sometimes described as a complication of sand-crack, it appears to us more rational to rather regard the sand-crack as a result or complication of the vice of contraction. the overlapping of the edges of the crack before referred to occasionally gives rise to the condition known as false quittor. a probe or a director passed beneath the overhanging ledge of horn reveals sometimes a fissure of 1 inch or considerably more in depth, and quittor is diagnosed. a careful paring away of the overhanging horn, however, reveals the true state of affairs, and exposes to view the original cause of the mischief--a simple fissure in the wall. a serious complication--one fortunately met with but rarely--is that of keraphyllocele. this is a tumour-like growth of horn, varying in size from the thickness of an ordinary quill pen to that of one's middle finger, growing down from the coronary cushion, and attached to the inner side of the wall of the hoof. with this lameness is always present, and more or less deformity of the hoof results. this condition will be found described at greater length in chapter ix. _prognosis_.--in the case of sand-crack this should always be guarded. it may be taken as a general rule that cracks commencing from the coronary margin are more troublesome to deal with than those originating below. the reason is not far to seek. they here affect the wall just where the bevel in it for the accommodation of the coronary cushion has rendered it weakest. not only is it weakest, but being more resilient than the portions below it, it suffers more from the alternate movements of expansion and contraction of the foot than does the horn below. although in many cases a cure of the existing crack may be easily accomplished, regard should be paid to the possibility of its recurrence, either in the same position or elsewhere. really, in offering an opinion as to the future usefulness of an animal so affected, a greater attention should be directed to the animal's conformation than to the crack itself. where the vice of conformation giving rise to it (as, for example, contracted heels or upright hoof) gives hope of being remedied, then naturally it may be safely said that the liability to sand-crack goes with it. a like favourable prognosis may be given in the case of cracks occasioned by purely accidental causes. ordinarily, however, cracks once commenced tend rather to increase than decrease in size and severity. from being superficial and incomplete, they become complete and deep, with every unfavourable circumstance that an increase in size and depth brings with it. this much, however, may be promised to the owner. a simple crack, even though originating from the coronary margin, is, in the vast majority of cases, curable. under a rational treatment its increase in size may be prevented, and a sound wall caused to grow down from the coronet. _treatment_.--the principles governing the treatment of sand-crack are simple enough in themselves, if not always followed by success. 1. _preventive_. this, as a rule, does not suggest itself until a crack of greater or less extent has made its appearance. then, simultaneously with the treatment proper of the lesion, preventive measures should be adopted, to aid both in the healing of the fissure already present, and to ward off the occurrence of others that might be likely to form. the hoof, if abnormally brittle, should be regularly dressed with a suitable ointment (one containing glycerine for preference), and its horn kept as nearly as possible in a normal condition. when the condition of the horn predisposing to its fracture is brought about by excessive wet, then the appropriate preventive measures to be adopted suggest themselves. with regard to the lesion itself, we may term 'preventive treatment' all those measures having for their object the prevention of increase in the size of the crack. they are as follows: _(a) blistering the coronet_.--in a simple case, where the crack is superficial and close under the coronary margin of the wall, a sharp cantharides blister to the coronet immediately above it will have the desired effect. an increased secretion of horn is brought about, and by this simple means the crack prevented from becoming longer. very often this is all that is necessary. in fact, we may say here that, no matter what other treatment is adopted, the simultaneous application of a blister to the coronet is always beneficial. to derive full advantages therefrom, the blistering should be repeated several times at intervals of about a fortnight. _(b) clamping the crack_.--when the services of a skilled smith are at hand, one of the readiest methods of performing this is to draw the edges of the crack together with an ordinary horse-nail. on each side of the crack a small horizontal furrow is burned or cut into the wall, leaving the horn for about 1/4 inch on each side of the crack intact. this provides a groove for the ends of the clamping-nail to rest in, and brings them flush with the outer surface of the wall. the nail is then driven carefully home through the crack, and the pointed end grasped by the farrier's pincers. the edges of the crack are then drawn tightly together, and the nail firmly clenched. [illustration: fig. 86.--the sand-crack firing-iron.] 'the horse-nails are prepared in the ordinary way as for driving, with the exception that each is pointed on the reverse side, to prevent puncturing the sensitive structures. before being used the nails are put in a vice, and the head hammered to form a shoulder, to prevent their being driven too far into the wall, and breaking out the hold.'[a] [footnote a: _veterinarian_, vol. xlviii., p. 100.] before driving the nail some operators burn or bore a hole for it. opinion seems to differ as to whether this is at all necessary. a method of clamping which, on account of its simplicity, has become greatly popular, is that of vachette. for this operation is needed the outfit depicted in figs. 86 and 87. [illustration: fig. 87.--the sand-crack forceps and clamp.] with the special firing-iron (fig. 86) an indentation, sufficiently large to admit the points of the clamp (fig. 87), is made on each side of the crack. the clamp is then adjusted, and pressed home tight by means of the sand-crack forceps (fig. 87). according to the length of the crack, one, two, or three clamps may be necessary. another useful clamp, though far more complicated in its structure, is that of professor mcgill (fig. 88). [illustration: fig. 88.--mcgill's sand-crack clamp.] 'the object of this invention is to arrange on a spindle, which is screw-threaded at one end with a right-hand thread and at the other with a left-hand thread, two clips or clamps, free to travel on the thread, there being a nut between the two which can be turned by a spanner. the clips are placed on the hoof, one on each side of the sand-crack, the hoof being prepared to receive the instrument by filing a groove or notch for the clamps to fit into, and by turning the nut on the screw the clamps are brought towards each other, and the crack thus prevented from spreading.'[a] [footnote a: _veterinarian_, vol. lxi., p. 141.] still a further useful clamp is that of koster. this is considerably broader than the clamp of vachette, and its gripping edges are provided with teeth (see fig. 89). as with the clamp of vachette so with this, a groove is burned into the wall on each side of the crack for the accommodation of the jaws of the instrument, and the clamp itself pressed home by means of a special pair of forceps. this form of clamp holds well, and has the advantage of securing a wider area of horn than that of vachette or mcgill. [illustration: fig. 89.--koster's sand-crack clamp.] clamping by any method should be advised or undertaken only under certain conditions. the horn should be moderately strong, and the wall should be thick. this practically restricts the use of the clamp to cracks of the toe, and it is there, as a fact, they are found of most benefit. while burning the grooves for the clamp, and while tightening the clamp itself, the animal's foot should be on the ground and bearing weight at the heels, thus insuring the greatest possible approximation of the edges of the crack. with all methods of clamping an untoward result is sometimes the formation of a fresh crack at the point of insertion of the clamps. (c) _by the use of thin metal plates_.--these are of use when the horn of the wall is too thin to allow of clamping, and are therefore of especial use in cracks of the quarters. the plates are made so as to cover the greater part of the length of the lesion, and are fastened to the wall by two or more screws on either side of the crack. it is an advantage to slightly let the plate into the wall by means of fitting it hot. in a complicated crack the plate serves the further useful purpose of holding in position antiseptic pledgets, and so keeping the lesion free from dirt and grit. _(d) by various methods of bandaging the whole circumference of the wall_.--in our opinion this method of attempting to secure immobility of the crack, and so prevent its extension, is not often followed by success. the main objection to the method is that it subjects the whole of the wall to the same pressure, and does not restrict the operation to the point at which it is required. as in the case of the metal plate, however, this method has the advantage that antiseptic dressings may be kept in position in the case of a complicated crack. [illustration: fig. 90.--sand-crack belt.] the binding of the wall may be accomplished in two ways. the simpler of the two is to merely apply the sand-crack belt depicted in fig. 90. beneath this should be applied a compress of tar and tow or other material, and the whole tightened up and kept in position by means of the buckle and strap. this method of binding admits of after-tightening should it unfortunately work loose. the older method of binding the wall, and one now often practised by the smith, is to use a quantity of so-called 'tar-band' or other stout cord. with this the foot is neatly bound after the manner of a cricket-bat handle, and all movement of the crack apparently restricted. there is always a tendency, however, for such a dressing to work loose, and in the case of a complicated crack it has the disadvantage of permanently hiding from view the changes taking place in the discharge from the fissure. _(e) by wedging the crack_.--this is the exact opposite of clamping. whereas in clamping we obtain immobility of the crack by keeping it fixed in the position of greatest approximation of its edges, in wedging, the crack is rendered free from movement by maintaining it in that position where its edges are most widely separated. in this case the edges of the crack are pared smooth, the cavity thoroughly cleansed, and a wedge of hard wood firmly driven in so as to fit exactly the fissure. on the face of it it appears that this procedure would really tend to force open and so lengthen the crack, especially at its coronary extremity. what one should really remember, however, is that the crack _is not made wider_ than before, but that it is simply maintained in a position occurring with every contraction of the heels of the foot, when it is normally at its widest. movement of the edges is thereby stopped, the immediately surrounding structures are rested, and a new growth of horn, free from crack, induced to grow down from the coronet. this method of treatment only serves to emphasize the fact that, with a sand-crack once formed, it is the constant movement of the parts that tends most to keep it in existence, and not any particularly marked exertion of force. some practitioners, with the wedge, apply also a clamp, thus assuring additional firmness and solid
