IDENTICAL CHANGES 



of force must come down to the universal unit of 

 force, namely, one Primary Sphere changed from 

 organization to void matter, and the corresponding 

 change of one Sphere from void matter to organ- 

 ized matter. 



Positive electricity will be generated in Glass and 

 negative electricity in sealing wax with the same 

 friction. Yet with either material both kinds are 

 produced simultaneously. Only in the case of one 

 the positive goes to the substance rubbed and the 

 negative to the substance used for rubbing, and in 

 the other the negative goes to the substance rubbed 

 and the positive to the substance used for rub- 

 bing. 



And this positive and this negative may be in a 

 manner stored up in separate bodies, and, there- 

 fore, it lies near at hand to attribute to electricity 

 a dual nature, to take for granted that electricity 

 is an inherent attribute of the atoms of all matter, 

 but is in ordinary satiated in the union of the two 

 kinds, and that electrical excitation is the result 

 of the separation of the two kinds, and electrical 

 energy the result of the reunion of the two kinds. 

 This is, in fact, the generally accepted theory of 

 electricity, and under it electrical science has made 

 wonderful progress and innumerable observations 

 have been made. But there seems under this the- 

 ory to be very little hope of further theoretical 

 advance, because any inherent attribute of either 

 matter or force is beyond the scope of human rea- 

 soning.
