7. Nature of Current during Slow Polarization. 



The electrical movement within the substance during slow 

 polarization may be a translation of free electrons, as in 

 metallic conduction, a transfer of charge, as in electrolysis, 

 or a separation of the internal charges of the molecule, so 

 that its electrical moment increases. 



In order to determine which of these occurs in the present
