From these results we see that even in highly compressed oxygen 
and, as regards to Ag, in the strongest fields, these A’s will be 
negligible. 
When we take into consideration that the contributions found in 
(23a) and (23c) are only the first terms in series of ascending powers 
of hv, ($4 the end) and that in our case Av, is about 4.7, then it 
is evidently quite possible that the further terms in that development 
will preponderate. Even then those terms might be almost negligible, 
but further the value of A that we should obtain by using those 
terms would show a still greater dependence on 7 than was the 
case with the values given in (24) (unless over a certain temperature 
interval a very special compensation might occur). Then it, would 
still less agree with a value of A that may be regarded as constant 
throughout a certain temperature region. 
Thus an explanation of the experimental deviation from Curie'’s 
law, based on the directing action of the electrostatic forces between 
the molecules seems to be excluded, unless the directing action 
occurring in the liquid state might preponderate to a special degree. 
In the following §§ will be shown, that this conclusion remains 
valid also when we suppose the magnetic dipolar axis to be per- 
pendicular ') to the quadrupolar axis.

moment in a fixed direction perpendicular to the quadrupolar aavs,

In Fig. 3 OQ, and OQ, again 
represent the directions of the qua- 
drupolar axes of the two molecules. 
The directions of the magnetic dipo- 
lar axes have now been indicated 
'-by OB, and OB,, fixed by the angles 
w, and w, (from O to 27) and

We shall now follow step by step 
the calculations of § 3, of the for- 
mulae given there we have only to 
change the following ones. We now 
have the coördinates:
