specimens, the normal individual being understood to be one with 
eight tentacle groups, eight genital bands, eight colleto-eystophores 
and four well-formed septa. The variations occur in the tentacle 
groups, the genital bands, and in the number and position of the 
colleto cystophores. In some cases there is an extra collecto-cystophore, 
which may be on the edge of the arm of the tentacle group, or within 
the margin the inner surface of the bell, or even outside the margin. A 
peculiar variation occurs in the collecto-cystophorus, themselves some 
of them sometimes bearing a small capitate tentacle. The variation in 
the genital bands may be due to an apparent splitting of a band or even 
to a fusion of one band with a ninth or supernumerary one. Two 
variations in the tentacle groups are interesting. In one individual 
figured there are seven perfectly normal groups, and one abnormal 
rather small group occupying a position within the margin upon the 
inner surface of the bell. Its normal position on the margin is occu- 
pied by a large colleto-cystophore with a capitate tentacle. In the 
other case there are likewise seven normal groups. The eighth is 
normally placed, but is small. Somewhat outside of it there arises 
a supernumerary arm bearing an apical group of tentacles and another 
or proximal group. On each margin of the arm is a colleto-cystophore, 
thus raising the number of these to ten. It may also be said that the 
eighth genital band corresponding to the abnormal tentacle group is 
double. 
The author adds that mutilated individuals may reproduce a part 
that is or is not Jike the original, and that in some cases these mutilated 
forms bears a close resemblance to others that are congenitally abnor- 
mal. This being the case, it may be said that his observations show that 
there is considerable room for experiment to determine why the repro- 
duced part is not like the original, and to what extent it may differ.

The Role of the Liver in the Anti-coagulating Action of 
Peptone.’—E. Gley and V. Pachon have performed certain experi- 
ments that not only demonstrate the correctness of the earlier conclu- 
sions of G. Fano, that the anti-coagulating action of peptone injected 
into the blood of an animal is indirect, but also localize the intermedi- 
ate agent. The experiments consisted in ligaturing the lymphatic 
vessels leaving the liver in a dog previously morphined and chloro- 
formed, and then at intervals drawing blood from the left carotid and 
from the sphenal vein.
