A31214	Castelli, Benedetto, 1577 or 8-1643.	Of the mensuration of running waters an excellent piece written in Italian by Don Benedetto Castelli ... ; Englished from the third and best edition ; with the addition of a second book not before extant / by Thomas Salusbury.	1661.0		.xml	application/xml	52588	1182	49	And my doubt arose from my frequent observation of many Trenches and Channels , which carry water to turn Mills , in which Trenches , and Channels , the water being measured , was found pretty deep ; but if afterwards the same water was measured in the fall it made to turn the Wheel of the Mill , it was much lesse , not amounting often to the tenth part , nor sometimes to the twentieth , insomuch , that the same running water came to be one while more , another while less in measure , in divers parts of its Channel ; and for that reason this vulgar manner of measuring running Waters , as indeterminate and uncertain , was by me justly suspected , the measure being to be determinate , and the same . And to explain all more clearly with an example ; we suppose a Vessel filled with Water , as for instance a Butt , which is kept full , though still water runneth out , and the Water run out by two Taps equal of bignesse , one put in the bottom of the Vessel , and the other in the upper part ; it is manifest that in the time wherein from the upper part shall issue a determinate measure of water from the inferiour part there shall issue four , five , and many more of the same measures , according to the difference of the height of the Taps , and the distance of the upper Tap from the Superficies and level of the water of the Vessel : and all this will alwayes follow , though , as hath been said , the Taps be equal , and the water in discharging keep the said Taps alwayes full .	cache/A31214.xml	txt/A31214.txt
