56 New Theories of the Great Forces. 



New Light. 



More recent discoveries verify the presence 

 of this comparatively unappreciated constitu- 

 ent. 



The process of induction has ever been a 

 great mystery in electrical science. Magnetic 

 currents are known to act upon bodies in 

 close proximity without the intervention of a 

 spark, and to indue such bodies with mag- 

 netic force. This action, called induction, 

 has been supposed to be limited to short dis- 

 tances. This we believe to be erroneous. In 

 order that the inductive process take place, it 

 is only necessary to suppose some impulse to 

 be superinduced upon some pervading me- 

 dium. This medium we recognize in the 

 static vito-magnetic constituent of the atmos- 

 phere. Magnetic or electrical induction is 

 therefore nature's effort towards an equili- 

 brium. Newly-discovered phenomena show 

 that this process is carried on even at consid- 

 erable distances. To Prof. LOOMIS of New 

 Haven, Conn., we are indebted for experi- 

 ments which illustrate this fact. These ex- 

 periments show that magnetic communica- 

 tions may be made through ten miles of 

 space without the intervention of visible
