The Earth a Great Magnet.

Everything on tho earth and in the air above is permeated with the earth's magnetio foroe— it goes through your clothes, it pene-

tratos your bodies, it saturates your brains — it is a part of life itself. Gang, the illustrious £erraa.n astronomer, has computed (taking -is a unit of his measure a magnet, fourteen inches lone, one inch wide one fo'irth iuch ohick weighing one pound, mtide of the hardest steel and of the strongest magnetic foroe possiblo( the earthY magnet c force a^ eqnal to 8,464 000,000 000,000 000 000 fiu^h magnets. Tiie attiaeting or lifting power of such a magnet is about ten pounds, which would make the attraotive power of the earth 42,310,000,000,000,000,000 tons. If this magnetism were equally distributed throughout the mam at the earth, the magnetic intensity of eaoh oubio yard would be equal to six erf these magnets, or about sixty pounds attraotive force. Professor Mayer has shown that this magnetic influence, this invisible foros, is a power filling space to an unknown distance and radiating in the lines of magnetic forca very much as the rays of the sunlight, th« lines of the earth's magnetic force being from south to north, as indicated by the compass needle. — Horological Nnot.
