quantity «,, in a= a, + 2a,, +a,, in which a, and a, now refer 
to the attractions between the homonymous atoms of e.g. two 
molecules HCI, is always == Wa,a, so that a becomes = Wa, + Wa)’, 
and therefore Ya = Ya, + Va,"). 
It is now clear that not the values of a, but those of “a must 
be found to be additive ©. 
Well, we shall prove in the following tables that the values of 
Va can be built up additively from the following fundamental 
values for Vaz X 10°.

As has already appeared from the table for the fundamental 
values of 5 and is now again confirmed, H belongs genetically to 
the series C. N, O etc, and does not stand separately somewhere 
above Li in the periodic system. The monatomic noble gases again 
form the continuation of the different series. The value of Ne seems 
a little too great that of H too small to us.

1) The relation a. = ad, will evidently have to hold for homogeneous 
mixtures of two substances 1 have always held to this relation of BerrHeot’s 
in different earlier papers. I am more than ever convinced, that everywhere where 
t 
a Vajda, has been found, association or molecular compounds occur. Whenever 
it is possible to eliminate these disturbing influences by calculation, a3 = Vajda 
will always be found back. 
2) WarpeNn and Swinne (Zeitschr. für physik. Ch. 82, 289 (1913)) cursorily 
mention the partial additivity of the “specific molecular cohesion’’, i.e. of @ or 
afs. They too — like Marnews — seek connection between the values of a and 
the sum of the effective valencies. On Maruews compare the paper following this.
