EXPERIMENTS WITH TUBERCULOUS COWS. a BN 
SUMMARY OF RESULTS OF EXPERIMENTS WITH 
TUBERCULOUS COWS. 
BY CuS SRLS. 

In November of 1896 four Devon cows which had been 
condemned as tuberculous by the State Cattle Commissioners 
were brought to the Station for observation and experiment. 
When the herd of which these cattle were a part was first 
tested with tuberculin, in March, 1896, these particular ant- 
mals failed to respond to the test, although quite a number in 
the herd did respond, and were condemned and killed. On 
October 26 and 27, 1896, the balance of the herd was retested 
and the four animals which were later taken for purposes of 
experiment responded to the test. 
The following table gives the temperatures as obtained in 
October, 1896, in the tests made by the State Cattle Commis- 
sioners. ‘The official numbers given the cows at that time 
have been retained.

* Through the courtesy of the former Secretary of the State Cattle Commission we 
are able to publish the temperatures obtained in the tuberculin tests made prior to the 
arrival of the cows at the Station. These tests were made by Dr. L. J. Storrs.
