Archimedes’ Lever.

The famous Qreek philosopher, Archimedes was the author of the apothegm, *'‘Give me a lever loug enough and a prop strong enough and I will move the world.” The saying arose from his knowledge of the possible effects of machinery ; and, however much it might astonish a Greek of his day, would now be readily admitted to be as theoretically possible as it is practically impossible; for in the words of Dr. Arnott, 4 4 Archimedes would have required to move with the velocity of a cannon ball for millions of years to alter the position of the earth by a small part of an inch. This feat of Archimedes is, in mathematical truth, performed by every man who leaps from the ground, for he kicks the world away from him whenever he rises, and attracts it again when he falls.” , - A satirist says that tenors put oq more sirs than they sing,
