condition of the so-called “Eiweiszsalze” then depends on the pro- 
perties of the anion or the cation *). 
In a later publication, however, he communicates that the opposed 
charges of cations and anions do not come into play here *); he 
does believe though in a relationship between the action and the 
valency of the cation, viz. that the antitoxic effect increases with the 
valency of the cation *). 
As regards uranium there is, however, no ground for attributing 
its effect to the valency of the cation, for, then there must be a 
quantitative difference in the doses of the bivalent uranylion and 
the quadrivalent urano-ion, which difference was not revealed in 
my experiments. Consequently if neither the charge nor the valency 
play any part here, the only conclusion to be drawn is that the 
uranium-atom must be present in the ion. 
This atom then has a property that determines its action in 
RINGer’s mixture. This action is antagonistic and stimulating. 
A special investigation also taught me that the other elements of 
this group of the periodical system do not act likewise. I hope soon 
to be able to point out a new element possessing the peculiar 
property of potassium, rubidium and uranium, discussed in this paper. 
Anatomy. — “The relation of the plis de passage of GraTIOLET to 
the ape fissure’. By Dr. D. J. Hersnorr Por. (Communicated 
by Prof. C. WINKLER). 
(Communicated in the meeting of April 28, 1916). 
In a previous publication *) which I wrote, I came amongst other 
things to the conclusion, that the apefissure is an inconstant furrow, 
and that, in case it should be formed, it only takes place after the 
other principal fissures have reached total development. Moreover 
I explained, that not only in the different monkey species the 
fissura simialis can be formed in different places, but also that in 
the same species, the spot, within certain limits, can change. 
For instance one finds in semnopitheei and macaci the m + m’ 
suleus (s. par. oce. lat.) at one time on the frontal face of the 
ape fissure, at another time on the back of it, what naturally
