92. The like effects will follow by weights placed upon a syringe instead of ye weight of water or quick silver. For example. Let A B C D be a syringe of 3 inches large having its [[image: drawing of a syringe A B C D with an opening at the top E, with plunger P N weighted by Q R pressing on the surface of liquid O L M thourgh shaft F G to plate H G I]] going out a hole of 4 inches in E ye sucker is F G, wch hath a plate H I below its handle to wch it is fastened that ye syringe may be kept streight, ye sucker being within, it had water from ye top of ye sucker L to E, M N, O P, are two sticks tied to ye body of ye syringe on wch are hanged by two cords on each two equall weights Q and R: I say if these two weights weigh 20 pound, ye spout will spout thrô E as heigh, as if a reservatory, wch had communication with ye hole E, and whose pipe wch contained ye water was equal in thickness to ye body of ye syringue A B C D, was heigh enough to contain 20 pound of water Now ye pipe being 3 inches large it will have nine inches surface, each of which weighs 6 1/8 ouncees; there is therefore 55 ounces or 3 pound 7 ounces upon each foot in height, and if ye reservatory was 6 feet it would be 20 pound 10 ounces: Therefore ye spout should go about 6 feet supposing ye rubbing of ye sucker to be but ye value of 10 ounces: So if the two weights were of 40 pound, they would spout ye water to near 12 feet; and if they were of 100 pound it would spout as if ye pipe was 30 foot heigh.
