TUBERCULOSIS. 
217 
In China, the people do not drink the milk of the cow, 
and they are free from phthisis. 
Thus the statistics go on, and where the exceptions arise 
the cause is always evident in the conditions that influence 
the breeds af cattle. 
Taking into consideration all the foregoing facts, there 
can be little doubt that the inbred species of the bovine race 
is the prime astiological factor of phthisis in the human race. 
They not only nurse the germ, and prevent its extinction, but 
sow it in the human race continually and abundantly. With¬ 
out their aid the germ would die, for of all germs known none 
have so hard a struggle for existence in the human kind as 
bacillus of tubercle, when we consider the comparatively few 
of the human race who are afflicted, and the immense number 
who are exposed to the infection and escape it. The cow is 
the only known animal that has transmitted tuberculosis to 
her offspring in inheritance. Alter looking through all the 
works at my command, and making inquiries of prominent 
doctors, I fail to find a well-authenticated case on record of a 
human foetus at term showing evidence of tuberculosis. At 
the congress for the study of tuberculosis, held in Paris, in 
July of the year 1888, it was stated, and generally accepted 
by the members, that a large portion of sufferers of phthisis 
acquired the disease through the ingestion of infected milk or 
meat. When we come to consider the transmission of the 
disease through the use of milk and the ingestion of diseased 
meat, we reach a point of vital importance to every man, 
woman, and child, and the conviction that the consumption 
of milk of phthisical cattle constitutes a veritable danger is 
daily gaining ground. 
Since holding my present position, as veterinary inspector 
for the Bureau of Animal Industry at Armour Packing Com¬ 
pany, 1 find upon post mortem that the udder is more often 
affected than any other organ of the body, and always in cows 
with fine, large udders, and those that look high bred. 
At this period it seems to be customarj 7 to rear children 
on cows’ milk. I therefore think it time that health depart¬ 
ments had a regular inspection of all dairies. We have a so-
