Sun-Heat. 45 



Force: New tons "Higher and Still Un- 

 known Force" every one recognizes a cur- 

 rent constantly present, setting towards the 

 earth. That current is recognized as bring- 

 ing us our light and heat. But without a 

 retro-current, should we have a circuit com- 

 plete ? Should we have any of these phe- 

 nomena? 



Heat without Combustion. 



Neither in the battery nor near the bat- 

 tery do the phenomena manifest themselves. 

 Though the developer of light, heat, and 

 power, the battery itself is neither luminous, 

 hot, nor magnetic. "To explain the effects of 

 the sun, therefore, there is not the least rea- 

 son to infer that it is itself luminous, or even 

 warm. Potential action generated in a dark, 

 cold body, may produce great heat and light, 

 at a distance from the seat of activity ; and 

 what is thus wrought artificially in a small 

 way may surely be done naturally in a tre- 

 mendous fashion by the grand forces of the 



sun." 



Inter-currents. 



It is now well known that a number of 

 currents may pass in each direction, at the
