BULLETIN 66. 
dangerous to man. It is to be devoutly hoped that this 
is so, as it would greatly simplify the problem of ridding 
both man and cattle of the worst disease with which either 
is afflicted. Meanwhile, we should not cease using judicious 
caution and our researches are doubly interesting. The 
evidence against bovine tuberculosis has been sufficient 
excuse for all the laws and regulations enforced against it. 
At the close of the British Congress on tuberculosis, 
before which Professor Koch delivered his paper, a series 
of resolutions were adopted, among which appears the 
following, as published in Science, Aug. 1901: 
“That in the opinion of this Congress and in the light of the work 
that has been presented at its sittings, medical officers of health should 
continue to use all the powers at their disposal and relax no effort to prevent 
the spread of tuberculosis by milk and meat.” 
“That in view of the doubts thrown on the identity of human and 
bovine tuberculosis it is expedient that the government be approached and 
requested to institute an immediate inquiry into this question which is of 
vital importance to the public health and of great consequence to the 
agricultural industry.” 
There were over 2,500 members at this Congress in¬ 
cluding many of the world’s foremost scientists. 
THE TUBERCULIN TEST. 
Within the past year the restrictions of this government 
on the importation of tuberculous cattle has given rise to 
vigorous protests on the part of men actuated by selfish 
interests. Our own people submitted to like restriction 
without complaint, but enforcing such regulations against 
Canadian cattle has given rise to what we believe are un¬ 
warranted attacks on the reliability of the tuberculin test 
which is used to determine whether or not cattle are tuber¬ 
culous. 
We think it unfortunate that some of our leading stock 
journals have published attacks on the test, which are calcu¬ 
lated to mislead the public in regard to its efficiency and 
value. The highest authorities state that tuberculin is per¬ 
fectly harmless to healthy cattle when properly administered 
as a test for tuberculosis. They are also agreed that it is a 
means of detecting the disease which is of great value and 
sufficiently accurate to be practically infallible. Because it 
gives fever to diseased animals or occasionally fails to pro¬ 
duce its effect on such advanced cases that the disease can 
be found by physical examination does not seem sufficient
