42 New Theories of the Great Forces. 



It is a well-established fact that from the 

 equator to the poles a continuous magnetic 

 flood is ever in motion. 8 



In thus tracing the course of the magnetic 

 current from the sun to the equator, and 

 thence to the poles, a physical necessity, 

 made imperative by the inexorable law 01 

 conservation, indicates that a retro-current 

 from the earth back to the sun, must now 

 have part in the process. Should such be 

 the case, as all reason and philosophy affirm, 

 .we have a completed " Grand Magnetic 

 Circuit!' in' and through which all physica* 

 phenomena have their origin. But aside 

 from the logical necessity, we hold that there 

 are terrestrial phenomena, which, rightly in- 

 terpreted, point to just such a retro-acting 

 inter-communication. 



Old Phenomena, and new Interpretations. 



The phenomenon, the aurora borealis, or 

 polaris, has never been satisfactorily ex- 

 plained. It is acknowledged as purely mag- 

 netic in character, and to be due to the pas- 

 sage of currents upward from the earth. It
