PERPETUAL MOTION. The prevailing type. A wheelthat is furnished at equal distances around its circumference with levers, each of which carries a weight at its ex-tremity, and is movable upon a pin, sothat in one direction it can lie upon thecircumference, while at the opposite side,being carried along by its weight, it maybe forced to take the direction of a pro-longed radius. This granted, it will be seenthat when the wheel revolves in the direc-tion a, b, c, the weights. A, B, C, willdeviate from the center, and, acting withmore force, will carry along the wheel on this side. And since, inmeasure as it revolves, a new lever will turn up, it follows, it was said,that the wheel will continue to revolve in the same
