72 From Matter to Man. 



vast energies which make their influence felt in 

 various ways: — Firstly, as magnetism at the poles. 

 Secondly, as gravitation, or the magnetic attraction 

 of all external or isolated bodies to the earth's surface. 

 Thirdly, as gases, water, and molten material ejected 

 to the surface through volcanoes, geysers, and burning 

 and boiling springs of all kinds. 



These energies, however, are more or less ephemeral, 

 for unless these vast subterranean fires be kept supplied 

 with new fuel, they will gradually die out, and the 

 earth losing much of its present energy, shall retire 

 to an even more insignificant position than it presently 

 occupies in the universe. 



Alive, therefore, as scientists now are to these 

 stupendous subterranean forces and the energies 

 which the law of the Correlation of Physical Forces 

 involves, the next great feat of our inventors shall 

 probably be to tap the earth's great store of elec- 

 tricity, and from thence draw energy enough to supply 

 all the manufactories of the world. 



We have now furnished the requisite proof that 

 every atom is a magnet, and that its fundamental 

 energy is magnetism. The inference from this basis 

 is astounding, for not only . does it involve the 

 magnetism of the earth as well as the magnetism 

 of all the constituents of the earth, but it establishes 

 beyond a doubt the magnetism of all the products 

 of tlie earth — mineral, vegetal, and animal. Every 

 crystal, plant, animal, and man is thus a magnet, 

 whose every energy — muscular, nervous, vital, or
