PLANETS ARE ELECTRO-MAGNETS. 49 



is manifest from the calculations of the density of 

 the sun at only one fourth of the density of the 

 earth. Were our earth measured from the ex- 

 terior of the luminous coruscations of the aurora 

 above the atmosphere, its estimated density would 

 be similarly reduced. 



The uniform axial rotations of the planetary 

 bodies, by determining the regular circulation of 

 electric currents about each one of them, convert 

 them all into powerful electro-magnets, with the 

 consequent development of reciprocal action and 

 reaction between them all, denoted " the universal 

 attraction of gravitation." 



The swift orbital revolutions of the planets of 

 our system, and also those of countless worlds 

 revolving about other stellar suns, in rushing 

 through the electric ether produce continual vi- 

 brations, which impinge against the surfaces of all 

 portions of matter composing the material uni- 

 verse. The vibratory impulses being imparted 

 equally in opposite directions against all the ex- 

 ternal parts of bodies and molecules, neutralize 

 each other, and consequently molecules exist in an 

 electrostatic condition. By diminishing the vibra- 

 tory impulses against one side of a molecule, it is 

 ready to yield instantaneously to the predominant 

 impulses against the opposite side, with a quick 

 resultant movement resembling an " inherent 

 self-motive power" in lifeless molecules. This 

 explanation confirms the definition of molecules
