IDENTICAL CHANGES 



It seems, then, that a translucent body can per- 

 mit the passage of Primary Spheres, in light trans- 

 mission, only in a zig-zag course, while a body that 

 is transparent allows the passage of Primary 

 Spheres in continuous columns, everywhere one 

 P. S. pushing two others, in a straight line 

 between the transmitting body and the re- 

 ceiving body. Undoubtedly it is the prevailing 

 opinion that light directly penetrates all transpar- 

 ent bodies, even solid, transparent bodies. And, it 

 is said, that even in the most solid bodies at the 

 lowest temperature the atoms are clear apart from 

 one another. And each atom is surrounded by 

 ether, and light is a very rapid vibration of that 

 ether. 



Let it be granted that this is the case. (Hypothe- 

 sis.) Then, because under this Hypothesis the 

 whole of all the ether is in uninterrupted contact 

 there is no solid background anywhere. 



And when a certain amount of ether moves in a 

 given direction, all the ether must move with it, 

 or at least all the ether in all the planes wherein 

 the movement originated. And a ray of light must, 

 under this Hypothesis, penetrate all things, and all 

 things alike; there is no solid background any- 

 where. It is then evident that this Hypothesis 

 cannot stand the requirements of individual reflec- 

 tion or transparency of bodies. 



All force is Universal force and every move- 

 ment is a Universal Movement ; and yet every sub- 

 stanch is an Identity, and every motion is an identi-
