pounds (see under c). The same applies to group OH in COOH, 
C again being = 3,1 there. 
e. Some alcohols and amines.

For the amines the agreement is better than with respect to the 
values of hj; we should bear in mind that in consequence of V pz 
in the expression aj errors of pz are transferred to Waz for half 
the amount, passing to the full amount to bj. 
SUMMARY. 
If we summarize what. has been discussed above, it may therefore 
be said that also the values of Vax can be built up perfectly additively | 
from a few fundamental values. These fundamental values have 
been given at the head of this paragraph, and roughly it may be 
said that in the first series of the periodic system (H included) Va, 
is about = 38 (> 10-2); in the second series about 5; in the thire 
series 7, and in the fourth series 9. 
After this paper had been written we have seen that in the fourt 
series Sb—8,9 quite in agreement with I= 8,8, and NERO
