REVIEW OF THE ARGUMENTS OF THE RELATION 
OF BOVINE TO HUMAN TUBERCULOSIS. 
BY GEORGE H. GLOVER. 
The recent test of the College herd with tuberculin and 
the consequent discovery of tuberculosis among cattle which 
were supposed to be in perfect health has led to some con¬ 
troversy; on the one hand by those who, because of their 
knowledge gained by actual observations and experiments, 
and who having been trained to think and reason to logical 
conclusions, are warranted in expressing themselves; and on 
the other hand bv those who are not so warranted. 
m/ 
One thing in particular, more than any other, has 
inspired the issuing of this bulletin, viz: The evidence every¬ 
where extant, that since the stand recently taken by Dr. 
Koch, there has settled upon the public a determined dis¬ 
position to belittle the whole matter and throw precaution¬ 
ary measures to the wind. We urge upon all the warning 
that the difference between human and bovine tuberculosis 
has not yet been settled finally, and that precautionary 
measures for preventing the spread of the disease by butter 
and milk cannot be safely abandoned. It is one of the mis¬ 
fortunes accompanying the deliverance of such an uncom¬ 
promising thesis as that by Dr. Koch that obscurantists of 
every dye make it responsible for conclusions which are 
not warranted by the facts in the case. It cannot be too 
strongly emphasized that even if it be proven that bovine 
tuberculosis is not communicable to the human race, the 
necessity for the most scrupulous cleanliness in the manage¬ 
ment of cows and their milk production is as great as ever. 
This incident coupled with the perfectly reliable information 
which we possess that a large percentage of the dairy cows 
in Colorado supplying milk to our towns and cities (especially 
the latter) are consumptive, and that it is yet far from 
proven that this disease is not communicable to human beings 
by the use of such milk; and further, lest the recent stand 
taken by Dr. Koch results in a criminal laxity or indiffer¬ 
ence: have together inspired the issuing of this bulletin. It 
is not claimed that we have made any new or startling dis¬ 
coveries : the work among the College herd, so far as it 
has gone, has in every instance corroborated our claims
