then the numbers in the last columns should be constant for each 

 charging interval. This is not true, however, for the higher voltages

show a much greater percentage of residual formation than the lower 

 ones, as will be seen from the data of Table III. 



The residual throws from the condenser "Par. A" are expressed 

 in Table IV, for purposes of comparison, in terms of the total throw 

 which the charging voltage would have caused in the air condenser.
