PERPETUAL MOTION. Therolling ring which did not roll. It consistsof a stand, A, two idler pulleys, C, betweenwhich a hollow cylindrical ring, suspendedin the manner shown, is expected to re-volve in the direction indicated by thearrow. The only difi&culty about it is thatit will not work, though it looked plausibleenough to the inventor. 935. PERPETUAL MOTION. Differential water wheel. Fromthis arrangement it follows that the portion of sponge No. 4 which is about to quit the water is pressed upon byNo. 5 float and spring, which, from actingvertically, is most efficient in squeezing thesponge dry; while that portion of the spongeon the point of entering the water is notcompressed at all from its correspondingfloat No. 8, not having yet reached theedge of the water. By these means, there-fore, it will be seen that the sponge alwaysrises in a dry state from the water on the ascending side, while itapproaches the water on the descending side in an uncompressed state,and open to
