ON ELECTRO-DYNAMIC INDUCTION. 35 



before I had adopted the views given in this section, and since then I have 

 found (80) a more simple explanation of the alternation of the currents. 



93. In this number of my contributions, the phenomena exhibited by the 

 galvanic apparatus have alone been discussed. I have, however, made a series 

 of experiments on the induction from ordinary electricity, and the reaction of 

 soft iron on currents, and I think that the results of these can also be referred 

 to the simple principles adopted in this paper; but they require further exami- 

 nation before being submitted to the public.
