Two conclusions are suggested from these tables. 1st. 

 With a given voltage the percentage cathode activity de- 

 pends on the quantity of ether vapor present. 2nd. There 

 is no evidence that with high potentials a value at all near 

 100 exists for the percentage cathode activity. This evidence 

 points to the conclusion that part of the rest atoms are initial- 

 ly charged and part uncharged, and that the relative amounts 

 of charged and uncharged rest atoms depend on the relative 

 quantities of ether and air.
