 potential demands. 



In a general way, the relation between current strength and 

 time is represented in tig. 3, which is drawn from data obtained

in a chlorine determination. The anodic potential was held at 

 its maximum value by constant adjustment of the voltage, and 

 from time to time readings of the current strength were made. 

 It is seen that the current falls off very rapidly at first, but 

 much more slowly after the halogen concentration has become 

 low. This variation of the current strength with time depends
