A descriptive and historical account of hydraulic and other machines for raising water, ancient and modern : with observations on various subjects connected with the mechanic arts: including the progressive development of the steam engine . No. ;6. No. 257. ,?526 Siphons used hy Chcmut;. [Book V. in operacion by the .ungs. Moreoer cocks and valves of metal are actedr>u )^ acids, and in sone la^es vVOild affect or destroy the olthe fluids No. 259. No. 260. No. 861. No. 1268. No. 2S shows how hot or corrosive liquids may be drawn off from awide mouthml bottle or jar. The short leg of a siphon is inserted thrcMJgh\he cork ; and also a small tube, through which the operator blows, andl)V the pressure of his breath forces the liquid through the siphon. No. 259 represents a siphon sometimes employed by cherni^ts. Whenused, the short leg is first placed in the fluid to be decanted, the flame of«i lamp or candle is then applied to the underside of the bulb ; the heatrarefies the air, and conseijuently drives out the greater part of it throughthe discharging orifice. The finger is applied to this orifice, and as the bulbbecomes cool the atmosphere drives up the liquid into the void and putsthe instrument in operation. No. 260 is a siphon by M. Collardeau. It is charged by pouring aquantity of the fluid to be decanted into the funnel ; the bent pipe attachedto which terminates near the top of the disc
