BOVINE TUBERCULOSIS. 
TREATING ON THE DANGER FROM COW’S MILK, AND THE 
LEGISLATIVE CONTROL OF BOVINE TUBERCULOSIS.

While Dr. Peters, when he was Chief Inspector of Stock 
for New York State, in a report to the United States Veter¬ 
inary Medical Association in October, 1893, said: “In sus¬ 
picious cases when doubt is felt as to whether an animal is 
tuberculous or not, it is well worthy a trial; and in herds 
where a number of cases of tuberculosis are found, I believe 
it to be advisable to test the entire herd with it. I do not, 
however, believe it necessary or practical to go to every 
farm in the country and test with tuberculin every cow to be 
found ; but if it be inspected in the ordinary way and found 
to be healthy, I consider that sufficient.” 
From this it is evident that those best able to judge are 
not unanimous in their opinion as to the best methods to 
adopt. 
In discussing the question before the Legislative Commit- j 
tee the Cattle Commissioners referred to the measures so sue- 
cesslully adopted to suppress contagious pleuro-pneumonia in 
this State. Further, the Governor in his inaugural address 
referred to the success attending the adoption of these meas- 
ures, thereby leading to the supposition that as these meas¬ 
ures were so successful in combatting contagious pleuro¬ 
pneumonia, they would probably be equally successful in 
combatting bovine tuberculosis. 
Now, it seems to me that these two diseases are entirely 
different. Contagious pleuro-pneumonia is an extremely 
rapid and fatal disease. According to the special “ Report 
on Diseases of Cattle,” published by the Bureau of Animal 
Industry, the disease will develop in from three to six weeks 
after exposure, and often acute cases are fatal in from seven to 
twenty days after the animal is attacked. On an average 
40 per cent, (and according to some authorities 80 per cent.;
