of one or two lines ye spouts do not go so heigh at ye same height of ye reservatory as those of 5 or 6 lines and yet they give water sensibly in proportion to their holes.  To know ye causes of these different effects we must consider that ye small globes are in proportion to ye great in a triple proportion of their diameters;  but they are retarded in their motion by ye air according to ye surfaces of their great circles, and they force this resistance of ye air according to ye difference of their weights as is explained above.  Whence it happens that if we fire a musket charged with bullets and small shot, ye bullets will go further than ye small shot, althô they go out of ye musket with ye same swiftnesses as we have explained.  Ye same thing extends to ye small and great passages, wch have ye same height of ye reservatory.  For althô at ye going out of ye passages they go near as swift one as ye other when they pass much air, ye small spouts are retarded from their going out to their greatest height more in proportion than ye gross spouts, and by consequence ye gross go heigher than ye small, but they give not more water in proportion, or but little more since it ought to be esteemed by ye swiftness wch ye spouts have at their first going out of ye passage, wch is near equall in both small and great passages.

  When there is a spout maintained by a sufficient quantity of water, and we pierce ye pipe of ye conduit with a hole equall to that of ye passage thrô wch ye water goeth out, we shall find ye diminution of ye first spout in ye manner.

   Let A B C D be a reservatory of 13 feet heigh above ye passage H of a hole of 6 lines, ye spout ought to be about 12 1/2 feet if ye conduit is 3 inches large.  There is made a hole in I of 6 lines whence goeth out ye water I L;  ye spout HM expends 4 inches of water by ye rules wch have been given;  and because there ought to go out near as much thrô ye hole I, ye conduit is too strait to give ye same height to two spouts equall to H M;  therefore as soon as we permit ye water I L to run, ye spout H M will diminish a little and because ye two holes H and I give near 8 inches and that ye water N O which furnisheth ye water of ye reservatory is but 4 inches by ye supposition, ye reservatory will be void by little and little if it is very spatious and very swift if it contains but half a muid or 100 pints.  It is therefore necessary that ye water descend in ye pipe till ye spout H M gives but 2 inches: for then ye hole I giving
