Erxstrin considered the attractive action of the molecules as a whole, 
which was absorbed by the surrounding molecules. 
A glance at the values of Waz 
for CCl,, GeCl,, and SnCl, 
is 
already sufficient to convince us of the truth of what has heen 
said. They are namely almost equal, resp. = 20,0, 21,5, and 23,5, 
yielding for Cl the mean value 5,4, the same value as is also found 
from other compounds (e.g. Cl, itself). 
And the same thing is found for NH, and PH,, where Waz is 
found resp. =9,2 and 9,8, corresponding with H = 3,2 as mean 
value, also again the same value as is found for H in H,O and HC].

We see again at first sight that the values of Va, for carbon

proportional to the number
