UNSUSPECTED POISONING BY MEAT AND MILK OF TUBERCULOUS ANIMALS. 663 
cept one or possibly two were found to be tuberculous, and 
nearly all the tuberculous animals showed a reaction to tuber¬ 
culin. 
Tuberculosis, but giving no well marked reaction, were Nos. 
52, 53 and 58; of these No. 52 had previous been declared 
tuberculous after the ordinary examination. 
No. 53 had only a small nodule, not of recent formation, in 
one lung, and may therefore be excused for not reacting. 
No. 69 was a healthy cow and showed no reaction, and Nos. 
68, 70 and 71 did not react and were found free from tubercu¬ 
losis. 
No. 72 reacted but no tuberculosis was found upon post¬ 
mortem examination. 
In the cases of Nos. 52 and 58 the reaction may have been 
tardy in making its appearance, as it sometimes is, and then 
spoiled by giving them cold water at the time they were 
allowed to drink, although unfortunately this argument applies 
to all those that did not react. 
In the case of No. 47 the tuberculin seems to have given 
her ease, and caused the temperature to decrease slightly.

UNSUSPEGTED POISONING BY MEAT AND MILK OF 
TUBERGULOUS ANIMALS. 
By Prof. J. Law, M.R.C.V.S., Ithaca, N. Y. 
A Paper Read before the N. Y. State Veterinary Medical Society. 
With an unaccountable shortness of vision, medical and 
veterinary sanitarians alike have never, up to the present hour, 
looked beyond the infection by the tubercle bacillus in estimat¬ 
ing the dangers to man of tuberculosis in our flocks and herds. 
We find accordingly that the question kept continually before 
the public is that of the presence or absence of tubercle bacillus 
in food products—meat, milk, butter or cheese—furnished by the 
diseased or suspected animal. The question of the presence 
or absence of ptomaines or other toxic elements which are
