When the increase in conductivity obtained by separating 

 the plates is due to the genesis of new ions by the motion of 

 negative ions through the gas, the theory indicates that the 



™3 



ratios — , — , &c, should be equal. In most of the cases 



given in the above tables this condition is satisfied. When 

 the value of the electric force X is sufficiently large, other
