 curve. The higher frequency current was derived from 

 the secondary windings of a small induction coil with the 

 usual asymmetric wave.

is verified by the observations of Stone, Leduc^ and others. 

 Leduc'^ has given a law connecting the relations between 

 electrode surface and electrical resistance which involves 

 the length of the periphery of the electrodes, and not their 

 area. It would seem more important to connect the resist- 

 ance directly with the area of contact. Measurements of
