PERPETUAL MOTION. Mercurial wheel. A is the screwturning on its two pivots; B is a cistern to be filled above the level of the lower aperture of the screwwith mercury; D is a reservoir,which, when the screw isturned round, receives themercury which falls from thetop. A pipe conveys the mer-cury from the reservoir on tothe float-board, E, fixed atright angles to the center ofthe screw, and furnished atits circumference with ridges tointercept the mercury, the mo-mentum and weight of whichwill cause the float-board and screw to revolve, until, by the properinclination of the floats, the mercury falls into the receiver, E, fromwhence it again falls by its spout into the cistern, B, where the constantrevolution of the screw takes it up again as 376 PERPETUAL MOTION.
