[[image:  Top image (4) of an angular J-shaped pipe I L M N (O omitted from the drawing but included in the text) P. Q P is a plate at to at the P end of the pipe with a small nozzle projecting upward. Just below P Q are the letters y, R (inside the pipe), Z.  Bottom image (5) is a conical nozzle C A B D with two openings I at dotted line A B and dotted line E Q.]] 

I afterwards ye end of ye conduit like ye crooked figure I L M N O P in ye 4th figure and in ye plate Q P I put a passage like to that of ye figure marked S, it was a little conical but it had an inner plate represented by E Q, of an inch or better and ye upper plate A I B was pierced in I at ye middle with a hole of 6 lines wch was made to ye end that there might be no rubbing but at ye side of ye plate E Q within for there could be but very little in E A and B Q:  but it succeeded very ill:  for ye spout went less heigh and scattered more than it did thrô a simple conical passage which might come from ye different motions of ye water, wch having passed through Q E did strike violently ye plate A B at ye side of its hole, and being reflected might hinder ye rest of ye water from going out straight.  Lastly I put a well polished plate in P Q in ye 4th figure pierced with a hole of 6 lines round and polished.  Then ye spout was very fine and was elevated to 32 foot the reservatory being at 35 foot 5 inches, whereas ye other spouts were elevated but to 27 or 28 foot which happens because ye water takes ye direction of its direction of its motion from R and that it comes but very little latterally from ye sides Y and Z, wch nevertheless contribute to ye direction of ye spout, ye plate being very smooth and all be equall on both sides and stoping equally ye laterall motion on both:  Now ye spout thrô that hole was elevated to 32 feet without being seperated except in falling, and was stopped very little at ye top when it went to 32 feet, and much less than by ye other passages.  I have seen a plate pierced with a hole of 4 lines and of 6 or 7 small ones round about, wch made a kind of sheaf whole spouts were very fine and transparent, and that of ye middle was elevated to 18 foot.

  The spouts are necessarily enlarged as they are elevated whereof ye reason is that they diminish a little their swiftness, and because it is ye same water wch by its viscosity is kept united together without being seperated, it is necessary that it passes more space in ye space where it goeth less swift according to ye proportion of ye swiftness to ye swiftness.

  For ye same reason ye water wch runs thrô a hole of 5 or 6 lines when it is in ye reservatory but at ye height of 3 or 4 inches goeth always scattering till it is reduced into drops, when ye stream of water is become very small:  for there ought to be but a certain quantity of water in all ye spaces wch it passes through in falling, which in equall times are one to another at a range of odd numbers;  whence we see that ye stream of water may come at ye last finer than a hair, but before it comes to that point it is seperated and divided into drops, wch always accelerate their motion till they have acquired their greatest swiftness.

  We must not regulate ye expense of ye water by ye height of ye spouts but by ye swiftness of its going out thrô ye passage.  Now in ye passages
