potent properties of the above, but. without the cocci of ery¬ 
sipelas. 
This serum the authors call cancer serum. The mode of 
preparation is as follows: A sheep that had been inoculated 
with cultures of erysipelas is bled ; the blood is caught in 
sterilized vessels. After a certain time the supernatant serum 
is taken up in pipettes and freed from the cocci of erysipelas 
by filtration through Chamberlain filters. This cold, steril¬ 
ized serum is filled into flasks holding io cc., antiseptically 
sealed and kept in a cool and dark place. 
With this serum the authors attempted a cure in a num¬ 
ber of more or less hopeless cases of cancer. Only in two 
cases, in which a secondary injection and suppuration in the 
cancer occurred, was the serum useless. In all other cases a 
noticeable improvement showed itself in a short time. The 
authors will not maintain that on the basis of their observa¬ 
tions they have found a cure for cancer. Above all, the ex¬ 
periments are only a few months old, so that the following 
weighty questions—Is the serum a specific against all cancers 
or only against certain ones ? What is the dose ? How often 
repeated ? Is not the remedy dangerous ?—cannot be defi¬ 
nitely answered. 
The authors never saw any dangerous effects, even after 
30 cc. had been injected, as high temperatures, etc. A long 
list of experiments must be made by the authors before these 
questions can be determined.— Thierarzt Woch.

BONY DEPOSITS IN THE INTESTINAL WALLS. 
Bony deposits in the intestinal walls are extraordinarily 
infrequent. Drouin describes a case in which such deposits 
were present in the walls of the large colon. The autopsy 
held upon a horse subject to colics, the last of which resulted 
in congestion of the gut, complicated by rupture of the same, 
showed that the colon, a short distance from the seat of rup¬ 
ture, was covered with hardened nodules whose size varied 
from a pin’s head to that of a finger nail. These nodules, 
imbedded in the mucous membrane, were easily dislodged 
upon the slightest pressure. The microscope showed that
