Tuberculin in Veterinary Medicine. —Several months 
have elapsed since the statement of Dr. Koch, relating- to the 
use of tuberculin in the treatment of tuberculous diseases, 
was made public ; and also the publication of the constitu¬ 
ents and preparation of the wonderful lymph. Since that 
time numerous experiments have been made, and article upon 
article has been written, either recommending the use of the 
new therapeutic discovery, or condemning it in the most se¬ 
vere manner. The time has probably not yet arrived to an¬ 
nounce, in a positive manner, what are the real advantages to 
be derived from the use of the lymph ; but it is very evident 
that a great deal of what was expected has failed to be real¬ 
ized. 
In one of our late considerations of the subject we ex¬ 
pressed our regrets that experiments had not been made on 
some of our large domestic animals, which, from the fact of 
their being commonly affected with tuberculosis, we thought 
would have been excellent subjects to test the value of the 
tuberculin.
