PERPETUAL MOTION. The flotation problem. An up-right tank, through which passes a number of floats connected by aband of elastic rubber attached to their ends, leav-ing just enough space between them to secure actionon each side by the water. They are each of thesame weight as an equal bulk of water at the sur-face, therefore the upper one in the tank has nocomparative weight. The next lower one has aunit of upward force equal to the condensation ofits bulk of water, and so on, each adding a unit tothe upward tendency, until we come to the last, thepressure on which is altogether downward to theamount of the entire column of water; but wealready have a number of opposing upward forces,and when we look on the other side and see thethirteen active weights, it seems clear that therewill be a large surplus weight, over and above theopposing weight and the friction of the rollers and upper wheel. Theweights were to pass through an elastic cylinder at the 954. PERPETUAL MOTION. Liquid transfer. A wheel, eachof whose radii, A, B, contains a small channel through which there is a communication between the two bel-lows, C, D, one of which, C, is at theextremity of the radius, and the other,D, is nearer the center. The externalside of these bellows is loaded with aweight. It will be seen that on oneside (C, for example) the bellows far-thest from the center must open,and those nearest must close. A liquidhaving been poured into each radiusin sufficient quantity to fill its channeland one of the bellows, it is evidentthat on the side, C, such Hquor will be at the extremity, that is to say, inthe bellows that are ope
