CHAPTER IV. 



SUNLIGHT. 



Its Source and Nature. 



SUNLIGHT is one of the products of that 

 grand retro-action which is incessantly in 

 operation between sun and earth, and is, in 

 its intimate and essential nature, a vito-mag- 

 neticyfe^jf* (or so-called magnetic). Subtle, 

 and apparently intangible, manifesting itself 

 rather as a presence than a real substance, 

 it fills all the space between the sun and 

 earth which space may, with sufficient accu- 

 racy, be termed the solar cone or cone-space. 



Its Limits. 



Beyond the boundaries of the solar cone, 

 no light is. 



* This term is employed as being most exact and comprehensive, 

 as this fluid is now known to be the source of all life and all at- 

 tractions.
