34 The Cause of Life and Motion. 



as well as a stream of water. The light is no 

 doubt withheld by the perverted action of the 

 forces ensuing from the stream's movement, by 

 which the principle vibrations are caused to act 

 in a forward direction and convergent to the 

 stream, in a similar manner to what their action 

 would be on a moving body. 



SOUND. 



Sound is derived from the action of a body 

 upon certain active crystalline forms by which 

 they are temporarily changed and carried onward 

 In new forms continuously reproduced by the 

 Celestial forces. 



Sound crystals are comparatively large and 

 are not reflected well from polished even surfaces, 

 as such surfaces tend to scatter their component 

 elements. A good medium of reflection may be 

 had in a clean cut surface, having close and 

 minute indentations. 



If two musical keys or bars of steel of the -same 

 ilote should be placed in suitable positions at some 

 distance apart, and one of them should be made to 

 vibrate, the other would also vibrate; while a thjrd 

 bar of a different note, placed in some intermediate 

 position, would not be sensibly affected. The learned 

 scientist explains this by telling us that a certain series
