Our State Board of Health which has charge of tuberculosis 
in animals as well as in man, must take this matter up earnestly. 
A year ago this board was very apprehensive of evil results 
from the use of “tuberculin” as a means of diagnosis, and only 
reluctantly allowed me to use this agent in examinations I 
made for them, on the condition that I would personally bear 
all responsibility for untoward results. This I could afford to

and the pathogenic action of these on the tuberculous human 
consumer. Let our Health Board urge on the Legislature the 
necessity of providing means for the purification of our dairy 
herds, and municipal abattoirs where all animals destined for 
butcher meats will be scrutinized by professional government 
inspectors.

their triumphs to a body of mixed visitors in such a manner as 
to interest and instruct a reasonable proportion of the passing 
throng. 
Veterinary science in its broadest sense holds an unique 
place in science and art. On the one hand it holds a close 
relation to human medicine and becomes insensibly blended 
with it as a guardian to the health of man when considering the 
relation of animal to human diseases, while in the prevention 
and eradication ol diseases destructive to animal life it bears an 
important relation to economics, and, finally, although not
