NOTES ON TUBERCULOSIS.

many of which affect man and beast alike. In some of these 
diseases it is first necessary to control them in the lower animals 
before they can be controlled in man. In this work the two 
schools of medicine alone cannot succeed. The co-operation of 
the State legislature is deeded. The organization of an official 
body of scientific workers must be effected. Money must be 
provided for its use, for without the proper funds nothing can be 
done. The present Board of Health is not even allowed money 
with which to buy its postage stamps. How can the board be ex¬ 
pected to accomplish any good results under such circumstances? 
The most dangerous contagious disease that the veterinary 
and medical professions have to deal with at the present 
time is tuberculosis. I say it is the most dangerous of all 
the contagious diseases because it affects both man and beast 
alike, and because it is so frequently transmitted from the lower 
animals to man. 
This, until recently, has been one of the hardest diseases 
known to properly diagnose in all of its stages ; especially is 
this true in relation to the lower animals. It is hardly neces¬ 
sary to state here, however, that we now have a reliable and 
positive aid to the diagnosis of the disease in all of its stages, 
tuberculin , the modus operandi of which does not require a de¬ 
scription at this time, for the subject of my last essay is still 
fresh in your memory. For the introduction of this agent our 
thanks are due Dr. Koch, of Berlin. For the good results of 
its use in this country and the practical conclusions drawn from 
such, all or nearly all credit is due the veterinarians. As has 
frequently been stated, we now have a means at hand by which 
tuberculosis can be practically stamped out both among the 
human family and the lower animals. With this end in view, 
the veterinary and medical professions are working together, 
yet there is room for them to draw still closer together. They 
should mingle together in each other’s societies, thereby enabling 
them more effectually to co-operate' with each other. When 
this is done the importance of thorough and careful legislation 
for the suppression and control of contagious diseases will at
