Glanders. —Cultures are more sensitive to sarena in glan¬ 
ders than into tuberculosis. A 1-5000 solution is sufficient 
to kill the micro-organisms of glanders. I have sent to Ger¬ 
man and Russian institutes the result of these investigations, 
and have asked that similar experiments of control be made, 
and while waiting for a response I believe I am justified in 
saying that sarena is one of the most powerful of the antisep¬ 
tic preparations at our disposal as a disinfecting agent against 
communicable diseases. I have also made some experiments 
for the purpose of testing its properties upon putrefying solu¬ 
tion of organic matter. With a 1--1000 solution the breeding 
of cultures is impossible—an evident proof of the death of the 
bacteria of putrefaction. With a 1-5000 solution, twenty 
minutes’ application failed to destroy the bacterium germs, 
etc.; but it removed all bad smells. After two or three hours 
the power of growth in the bacteria is abolished, and the 
germs are destroyed. 
There is, in other words, a peculiar chemical decomposition 
which takes place in the solution, the nature of which 1 am at 
present unable to explain. Is it that the g owth of the micro¬ 
organisms is interfered with by an increase of their excretions ? 
Are they, as it were, suffocated in them? I believe that a 
molecular modification has taken place, but what ? Is it sim¬ 
ilar to that obtained with phenic acid ? All this requires more 
study and more experimentation, of the result of which I will 
at a later period inform you.

SURGICAL ANATOMY OF THE INGUINAL REGION IN THE 
HORSE. 
The first condition of success in the castration of cryptor- 
chids is a perfect knowledge of the direction to follow in the 
inguinal region in order to reach the testicle in ectopia. The 
most perfect asepsia would be powerless to insure success, if 
the hand of the operator should follow a wrong road during
