BULLETIN 66. 
look up the subject of the transmission of these germs from 
one animal to another, including man, we are at first sur¬ 
prised and then astounded at the seriousness of the con¬ 
ditions actually existing, and the grave possibilities which 
the tireless investigation by scientists may yet have in store 
for us. 
NOT CURABLE. 
Favorable climatic influence will often stay the progress 
of the disease for a time at least, but no climate or thera¬ 
peutical agent has ever been discovered which can in the 
true sense be called a cure. If ever anything is accomplished 
in either curing or preventing the disease it will most likely 
be in the direction of sero-therapeutics, but this is conjec¬ 
tural to say the least. 
RELATION OF BOVINE TO HUMAN TUBERCULOSIS. 
That tuberculosis is transmitted from one animal to 
another, and more especially from the cow to other domes¬ 
ticated animals, has been repeatedly proven so that it is 
considered a waste of time now to rehearse them. The 
whole subject is summarized by Dr. John Repp in an article 
read before the Iowa Tuberculosis Convention in this way: 
“ Enough has been done to prove beyond the peradventure 
of a doubt, that tuberculosis may be transmitted through 
the milk and the food structures of tuberculous animals, to 
the animals that consume these products or are inoculated 
with them, upon this all students of the subject agree. This 
much has been proven, but these facts do not decide the 
important question at issue, viz: whether or not tuberculosis 
is transmitted from animal to man, nor would they if they 
were multiplied ad infinitum, they only furnish a basis from 
which we may reason, for this purpose they are invaluable, 
as they establish the premise that the meat and milk of 
animals do, at times, contain living virulenttubercle-bacille.” 
If some of the incredulous will show the faith of their 
convictions by submitting themselves to a few “hypoes” of 
bovine bacillus-tuberculosis, or by voluntarily injecting a 
few of the same, it will supply the last link in the chain of 
evidence necessary to convict the cow of transmitting the 
disease through her milk and meat to her human bene¬ 
factors. 
As there is little probability of anyone offering in good 
faith to sacrifice themselves for the cause of science, let facts
