SOUND. 



Essential Character and Medium of Trans- 

 mission. 



SOUNDS are products of vito-magnetic con- 

 ditions and changes. They result from ac- 

 tion or force expended upon the vito-mag- 

 netic element of the atmosphere. If such 

 action or force be directly expended upon the 

 air, or, more accurately, upon this vito-mag- 

 netic constituent of the air, it is propagated 

 in accordance with the laws that govern the 

 transmission of the vito-magnetic or electri- 

 cal fluid through the air. If it be expended 

 upon a lengthened wire, then, as sound, it is 

 transmitted according to the laws of magnetic 

 transmission through wire. 



The recent experiments in connection with 

 the telephone have demonstrated the fact 

 that sound may be communicated through 

 hundreds of miles of space without occupy- 

 ing any appreciable length of time in this 

 respect being precisely like the ordinary ac- 

 tion of the magnetic current. It is most
