We have thus found experimentally a number of values of the resid- 

 ual charge which is formed in various charging times in various con- 

 densers. To get a rough but fairly correct insight into the behavior of 

 a condenser during the short charging intervals which have been used, 

 we may proceed as follows : Taking the experimental results in the 

 form of the residual charge, as expressed in percentage of " free charge," 

 we find the increments of residual charge corresponding to the incre- 

 ments of charging time. We measure off the various charging times 

 used in the experiment as abscissas, on any convenient scale. Then 

 we divide all the residual charge increments by their corresponding
