Table I contains the values of m, for the hydrogen atom 
calculated in the way described from the values of X for four 
liquids corresponding to the temperatures given in the table*. 
It will be seen that the values on the whole agree well with one 
another, the only serious deviation being shown by that obtained 
from ether. The mean value is 
1:56 x 10-* grm., 
which is very nearly equal to 1:61 x 10-“ grm., the value deduced 
by Rutherford from experiments on the a particle. 
Relations connecting Surface Tension with other Quantities. 
A number of relations have been found connecting the surface 
tension of a liquid with its internal heat of evaporation, co- 
efficient of compression, coefficient of expansion with rise of 
temperature, and other quantities. They should have as foun- 
* The values of L were obtained from a paper by Mills, in the Journ. of Phy- 
Chem. vol. yi. p. 405 (1904).
