should be kept in a place of even temperature ; take temperature 
of horse for at least twenty-four hours before injection at intervals 
of two hours, to be sure no fever is present. Take the tempera¬ 
ture the last thing before injecting, and then watch the animal 
carefully,—and if he is affected you will soon observe colicky pains, 
large amount of faeces passed, no appetite and trembling all 
over ; in about eight hours temperature will begin to rise, 2 0 to 
5 0 above normal, generally highest towards midnight; look for 
the swelling; if the temperature stays elevated for about thirty- 
six hours and does not disappear before that the horse is without 
doubt infected with glanders. But if all these symptoms ap¬ 
pear and disappear inside of twenty-four hours the case is a little 
doubtful; so after four or five days inject again. Brutes’ mallein, 
from France, is used in half cubic centimetre doses, diluted 
with two cubic centimetres of distilled water. The paper was 
well discussed by Messrs. Rosekrans, S. S. Buckley, Zucker, 
Wescott and DuBois. Adjourned.

Mr. Mead read a paper on u Tuberculin as a Diagnostic 
Agent in Tuberculosis.” A11 English Royal commission defi¬ 
nitely proved in February, 1890, that the meat or milk of any 
eatable from tuberculous animals could transmit the disease to 
healthy human beings or animals ; carnivora and herbivora are 
liable to it, but the pig is especially subject. Infection through 
the digestive track is mostly due to improperly cooked meat or 
infected milk. The tuberculous material is seldom found in 
the meat, but generally in the internal organs, membranes, and 
glands. Where tuberculous material is found on the meat it 
is generally due to want of cleanliness in handling. The 
udder is a very common seat of these deposits, and the nodules 
can often be felt by external manipulation. Therefore, milk 
from such animals is very dangerous. Some think that a good 
deal of the meat from a tuberculous animal can be saved without 
danger of infection to the consumer, especially if the seat of dis¬ 
ease be in the lungs or mammary glands. Human doctors try 
to keep life in their patients by keeping the system in such a 
condition that it can feed the destruction as fast as it breaks 
down. But in our patients it is better to kill at once and so 
prevent its spread. It is often difficult to diagnose an obscure 
case of tuberculosis, and the diagnosis is not alway positive. 
Tuberculin as a diagnostic agent was first prepared and used by
