Fig. 2 shows that this relation also is approximately 

 linear *. It denotes that the squares of the number of

44 dispersion " electrons are proportional to the radii o£ the 

 spheres of action of the atoms diminished by a constant. 

 This constant is about 95/100 of the radius of the sphere of 

 action of helium at 0° C. 



Relation between the Number of Electrons 

 and the Critical Temperature. 



If the squares of the relative numbers of "dispersion" 

 electrons are plotted against the critical temperatures of the 

 gases, the four known points fall nearly on a straight line 



* For obvious mathematical reasons these relations cannot both be 

 exactly linear. But they exhibit the broad relationships of the constants 

 sufficiently well for the present.
