TUBERCULOSIS. 
261 
Unlike other large cities and even smaller ones Chicago has 
never agitated the matter and nothing has ever been done to 
better the condition of our milk supply. In this connection as 
members of this society the duties of the veterinarian are plain. 
It will fall to our lot to present, for your consideration and dis¬ 
cussion, sensible and practical methods of dairy inspection ; 
methods which will result in the most good and will work the 
least inconvenience and loss both to the consumers and pro¬ 
ducers of milk, and at the same time be the least expensive to 
the public. 
The task of purifying the enormous milk supply of Chicago 
would, on casual notice, seem an equally enormous and expen¬ 
sive undertaking, but that this is not the case is exemplified in 
the experience of other cities where the sale of tuberculous milk 
is actually controlled at very little public expense. Minne¬ 
apolis is probably the pioneer in this work and Chicago could 
do no better than profit by their experience. This I mention 
to show the feasibility of cutting off one channel by which the 
human body becomes infected with tuberculosis. 
Now a few words on the extermination of tuberculosis from 
the domestic animals, which is a more difficult proposition than 
regulating the milk supply. To attain this end is quite as diffi¬ 
cult as in the case of human tuberculosis with the possible ex¬ 
ception of the ground the veterinarian gains through the slaugh¬ 
ter infected subjects, which of course the human sanitarian 
can never enforce. It is, however, safe to predict that human 
tuberculosis will exist as long as bovine tuberculosis exists and 
vice versa , and that one can never be exterminated without the 
other. Taws must be enacted, appropriations must be obtained, 
sanitary and other measures branching in many directions must 
be adopted, the public must be educated as to their needs and 
their danger, and finally many points of vital importance must 
yet be decided by the researching contingent of the medical and 
veterinary professions. 
The slaughter of all diseased animals, the disinfection of 
their habitats, together with the establishment of strict quaran-
