exhibit is infinitesimal. This latter point, however, is 

 immaterial so long as they furnish any evidence at all 

 of magnetic control ; it would obviously be extremely 

 inconvenient for all bodies to be equally magnetic 

 with iron ; besides, it would involve a virtual surrender 

 of each element's distinctive energy to that of iron. 

 Each element is master in its own domain and governs 

 with its own individual energy. 



We are now brought face to face with the following 

 facts : — All bodies belonging to the earth (including 

 meteorites) are amenable to the magnetism or attrac- 

 tion of the earth by falling to it. The property of a 

 magnet involves the manifestation of force more 

 intensely at its poles than at its equator or centre. 

 Thus, in sprinkling filings over a bar-magnet, the 

 particles adhere tenaciously to the poles, but weakly 

 at the equator or centre. Science reveals similar dis- 

 crimination by the earth, for it attracts all bodies with 

 greater intensity at the poles than at the equator ; 

 or, as Clerk Maxwell says, " The force of gravity at 

 the level of the sea increases from the equator to 

 the poles.* This fact demonstrates not only the 

 magnetism of the earth, but the, magnetic subjection 

 of all mundane bodies and constituents. For as all 

 substances and all elements sink their individual 

 energial differences into the attractive and repulsive 

 forces of the earth, the constituent particles or atoms 

 of all these substances, by exerting the same force 

 must also be magnets. In other words, all the atoms
