CONSTITUENTS OF THE UNIVERSE. 



only one part in a million of parts ot the 

 same size, could accomplish much in vibrat- 

 ing the other nine hundred and ninety-nine 

 thousand, nine hundred and ninety-nint parts 

 qf a cubic inch. What then are we to think 

 of this assumption, when a cubic mile or more 

 than twenty-one trillion of cubic inches are to 

 be vibrated by such insignificant means? But 

 there is no vibration about it, and light is not 

 transmitted in that manner. The supposed 

 Ether would be an obstacle instead of an agent 

 or assistant for such a purpose. Light is a 

 radial motion, and not a mere vibration nor 

 the result of a vibration. In short a vibration 

 ig nothing more than a mere local or second- 

 ary movement, if indeed it is even that; and 

 the same may be said of the so-called Wave 

 Motion. Neither of them are primary move- 

 ments like the movements of heat and light. 

 Both heat and light are radial, or the motion 

 that they follow or from which they result is 

 radial. The only other motion is the curved 

 one, and it will be seen at a glance that this 

 motion is not at all appropriate for such pur- 

 pose. The movements of heat and light re-
