Every case of tuberculosis comes from some other case of 
tuberculosis in either man or beast. 
There is no such thing as spontaneous generation of tuber¬ 
culosis. The germs causing the disease do not arise in that 
way. Every germ must come from a pre-existing germ, grown 
in a suitable medium, and must enter a suitable medium to pro¬ 
duce the disease in man or beast. 
Now, this man or beast may be a suitable medium for the 
disease, but if they never get any germs into their system they 
will never have tuberculosis. Then what must we do to prevent 
their taking the disease ? Why of course keep them away from 
the disease, and in this way keep the disease away from them. 
A large per cent, of the cases are caused by the inhalation of germs 
floating in the air, and which were thrown off by expectoration 
from human beings, discharges from the nostrils of animals, or 
from the bowels of both. 
These discharges are dried and float in the air, and are drawn 
into the lungs, or as in animals they are rubbed in troughs, 
posts, or other material to be licked up by the animal. 
But this is not the only way the disease can be contracted. 
Tuberculous meat and milk are responsible for a certain per 
cent, of these cases. 
Meat if properly cooked may be eaten with impunity, but 
we do not yet understand what is properly cooked tuberculous 
meat. A certain temperature may kill the bacilli but not the 
spores. So the safest way is not to eat it at all. In my judg¬ 
ment a large majority of bottle-fed children who die and are 
reported as marasmus, cholera-infantum and other wasting 
diseases, are nothing more than intestinal or meningeal tuber¬ 
culosis, caused by tuberculous milk. 
But there is another and very important side to this ques¬ 
tion, and one which our agricultural friends are especially in¬ 
terested in. 
The loss of cattle by this disease alone runs into millions 
of dollars. The property value of stock—those diseased—is 
hard to estimate, as no statistics to my knowledge have ever
