Comparing these values with those found in the use of method 25 

 the agreement is at once apparent.

It should be remembered, in comparing the results, that the values 

 obtained by method 25 would naturally be smaller than those found by 

 direct measurement, as in method 25 the current going through the 

 condensers was extremely small; there was therefore practically no 

 heating. 



The experiments that confirm the mathematical theory that the 

 absorption resistance could be treated as ordinary ohmic resistance were 

 performed with the two condensers, ^ Troy and ^ Elliott microfarad 

 condensers. These are next given. 



In these results it was necessary to take into account, in the calcula- 

 tion of the apparent value of R,, the last term of the equation, that is
