Not illustrated. 1845 Excerpt: ...water, screwed on for receiving the air; to be replenished with water as it becomes empty. P. 242. Fig. 286. A section of a compound stopcock, which receives a fluid from either of the pipes A,, or, into a cavity which descends a little in the direction of the axis, and communicates with the pipe D, by means of one of the bores represented by dotted lines, according to the position into which the moveable cylinder is turned. P. 242. Fig. 287. Valves of different kinds; A the common clack valve; a double clack valve, consisting of two semicircular valves; a pyramidical valve, consisting of four triangular pieces; D a circular valve turning on an axis; E a steam valve of metal, sometimes called a T valve; F, a valve of oiled silk or bladder, supported by a grating, for air.

The cord is drawn up, and the wheel fa is caused to revolve, at a time observed by a stop watch; and its surface is graduated so as to number the revolutions of the fly. P. 243. Fig. 289. An apparatus for measuring a ship's way, resembling aptain Hamilton's.

The tube H serves as a gage, to measure the velocit...
