and when he worked with negative oxygen,
In later experiments[33] he obtained 2.4 and 2.9, respectively, in place of the numbers given above, but in view of the unavoidable errors, he concluded that the two charges might be considered equal and approximately
. Thus he arrived at about the same value for
as that which was then current because of the kinetic theory estimates of
, the number of molecules in a cubic centimeter of a gas.
