CONSTITUENTS OF THE UNIVERSE. 



by insulation, as a flow of water is by a dam. 

 That it is a real motion is proved by the fact 

 that what is called induction is only a portion 

 of the current that is not confined strictly to 

 the conductor, and which in turn may be 

 transmitted by a parallel conductor, in an 

 opposite direction, and that has no other 

 current. 



There seems to be no limit to the imaginary 

 wonders that are attributed to this simple and 

 convenient mode of motion by those would-be 

 philosophers who fail lo comprehend it. Some 

 of them claim that there is nothing else in the 

 whole universe. How absurd that claim 

 appears in view of the fact that when, for 

 instance, this motion is changed into other 

 movements like heat and light by a sufficient 

 resistance or obstruction in its path, it is no 

 longer regarded as electricity, even by the very 

 ones who make this ridiculous claim. When it 

 is electricity it is not heat, and when it is heat it 

 is not electricity; but in each and every case 

 it is only motion, differently manifested. 

 Neither heat, electricity nor both of them
