The floats, when in motion, enter throughthe bottom of the tank, and rise up by their buoyancythrough the water; they then pass round the toppuUey, descend outside the tank, and, passing overthe bottom pulley, again enter the tank, and so cylindrical floats are used, as described, they arefij5:ed on the connecting links half a diameter ormore apart from each other. An absurd device isdescribed in this invention of 1865, for openingand closing the entering and exit valves of the chamber and the useof compressed air for operating 956. PERPETUAL MOTION. Mercurial displacement in acistern of water. A cistern fuU of water 4 feet deep. Let B be a wheel; freely suspended within it, letthere be four glass tubes 40 inches long,c, c, c, c, having large bulbs, holding, say,a pint, blown at the closed end. Fillthese tubes with mercury, fix on an In-dia-rubber bladder, that will hold apint, to each of them at the open end,and let them be attached round thew^heel, as in the figure. As the pres-sure of 40 inches of mercury will exceedthe atmospheric pressure, and also that of the four-feet column of water,when the India-rubber bottle is lowest, and the tube erect, as at D, themercury will fill it,
