     summary: The supposed economic necessity of slave labor led great men to defend slavery, and politics in the South became largely the defense of slavery against the aggression, real or fancied, of the free North. After one or two disastrous business experiences, such as fall to the lot of many great inventors, perhaps to test their perseverance, Watt associated himself with Matthew Boulton, a man of capital and of enterprise, owner of the Soho Engineering Works, near Birmingham.

     summary: He knew that the wire which carried an electric current was an electrified body, and still that all attempts had failed to make it excite in other wires a state similar to its own. In the autumn of 1831 he began to repeat the experiments with electric currents, which, up to that time, had produced no positive result.

     summary: Luca was recognised as one of the first sculptors of the day, and executed a number of great works in bronze and marble. The itch of writing is now so strong in us, we are so constantly writing or receiving letters, our appetite for them is so ravenous, that we wonder how people got on in the days when the postman was the exclusive messenger of the king, and when even majesty was so badly served that, as one old postmaster[D] wrote in self-exculpation of some delay, when placards are sent (to order the immediate forwarding of some state despatches) the constables many times be fayne to take the horses oute of plowes and cartes, wherein, he gravely adds, can be no extreme diligence.

     summary: At the bottom of the penstock is placed a turbine wheel fixed on a shaft, and to which shaft is connected an electric generator or other power machine. The introduction of the linotype and other modern machines into printing offices has without doubt many times reduced and displaced manual labour, and caused at those times at least temporary suffering among employees.

     summary: Of course there are many other places where poisonous gases are likely to be met with, such as gas-works, chemical-works, limeworks, and so on, where this apparatus may be kept with advantage, in case of accident. We now enter for a while the realm of organic chemistry, a branch of knowledge which is of supreme interest, since it covers the matters of which our own bodies are constructed, the foods which we eat and the beverages which we drink, besides a host of other things of great value to us.

     summary: This invention was a great boon to mankind, but not to Goodyear; for the jackals who lie in wait for great inventions eager to wrest unearned profit for themselves from the men who have truly earned it, made Goodyear's life miserable for many years. Though the typewriter is a very simple apparatus in both principle and construction, yet few machines stand out more clearly as great inventions.

     summary: Owing to the various kinds of skilled labor, numerous expensive tools, machinery, high rents for suitable manufacturing places necessary for the building of machinery, requiring the investment of large capital, and the devotion of a great deal of time for organization and supervision, many inventors find it convenient, even profitable, to have their machines built under contract by some established manufacturing concern which is properly equipped for that special kind of work. At present it would seem that many inventors have a special reason for deploring the decadence of the Eternal Brimstone-Doctrine, as punishment for wrong-doing, especially for the breaking of the Eighth and Tenth Commandments, as its modern substitute of Thou shalt not steal, less-than-necessary-for-lawyers'-fees-to-absolve-you-and-a-reasonable-margin-of-profit, manifestly is broad enough to include the stealing of inventive production.
