mals are shown in bold faced type. Unless the rise in tem¬ 
perature was more than 2.5 degrees it was not considered 
proof of infection. It will be seen that of the nine animals 
tested five, or 56.6 per cent, reacted.

The second test, principally of the Shorthorn cattle was 
made January 12. The results are given in Table II. 
No. 1, Young Grannie; No. 2, Lee Noble; No. 3, 
Gildana; No. 6, Lelia Rose; No. 7, Gildana 2d, and No. 
11, Ambrosia, were cows which were injected during the first 
test. An interesting point and one which has been urged 
against the test is that the Jersey, Lelia Rose, and the 
Shorthorn, Ambrosia, which gave reactions at the first test 
on December 8, failed to react to this second injection of 
tuberculin. It merely illustrates the fact that an injection 
of tuberculin renders an animal immune to the test for some 
time after it has been made. 
The time between tests of the same animal should 
probably not be less than six months, and the results of a 
test should not be accepted unless it is known that the ani¬ 
mals have not been injected with tuberculin for at least six 
months time. Therefore we did not accept the failure to 
react at this second test as an indication of freedom from 
the disease and at the post mortem Ambrosia proved to be 
about as bad a case as could exist and the animal continue 
to live, although she appeared fairly well and thrifty. 
Counting out the animals tested December 8, including
