MECHANISM OF NATURE 



Then because the changes wrought in matter by 

 electricity are not a displacement of ponderable 

 matter or cause an increase or decrease of mass, 

 therefore, electricity is in the last instance a dis- 

 placement of void matter. And because electricity 

 does not create force, there must be a displacement 

 of void matter pre-existing to any manifestation 

 of electricity. This displacement must now be 

 ever present and must in some manner be alternate 

 or there would be a general accumulation of mass. 

 Upon this displacement of void matter different 

 substances may take hold differently because of 

 their form, which constitutes their identity. Then 

 because finite substances cannot stop an infinite 

 current while yet they engage that current, there- 

 fore, they can only modify its velocity. 



PROPOSITION XXI. 



The transmission of light is effected through a dis- 

 placement of Primary Spheres of void matter, 

 which cannot loosely vibrate. 



Of all forces light seems to have the least rela- 

 tion to the mass of substances. In no known way 

 can light be determined in amount or intensity by 

 the weight or bulk of the substance which pro- 

 duces it, or upon which it acts. There is, there- 

 fore, no scientific unit of light, and the arbitrary 

 candlepower is the adopted standard. But sun- 

 light and artificial light are accompanied and, ac-
