102 STORRS AGRICULTURAL EXPERIMENT STATION. 
The first test after the cows reached the Station was made 
by the College veterinarian, Dr. George A. Waterman, January 
20-27, 1897. This was three months after the animals were 
condemned by the Cattle Commissioners. All four of the 
cows responded clearly to the test. In addition to the neces- 
sary rise of temperature (two degrees above the maximum be- 
fore injection), to indicate the presence of the disease, cow No. 
1337 showed a roughness of the hair at 9.30 a. M., the 27th, 
and Nos. 1341, 1343, and 1344 each showed a decided chill be- 
tween 9.30 A. M. and 3 Pp. M. The next two tuberculin tests 
were made by the same veterinarian. Three months later, 
April 26th-27th, all four of the cows were injected, , "Atathat 
time cows Nos. 1341 and 1344 responded to the test, while the 
other two cows showed no apparent results. None of the cows 
manifested any signs of chill. The next test was made about 
four months later, July 3oth-31st. At that time none of the 
cows gave an appreciable rise of temperature, nor did they 
manifest any physical symptoms, such as chilling or roughness 
of the hair. Late in September it was thought desirable to re- 
peat the test, and as the College was temporarily without a 
veterinarian, the services of Dr. L. J. Storrs were engaged. 
No response either in rise of temperature or physical symptoms 
was observed. 
The tuberculin tests which were made in December, 1897, 
April, 1898, and December, 1898, were conducted by Dr. N. 
S. Mayo, the present College veterinarian. In these tests the 
temperatures before injection were taken every three hours 
throughout the day, but only the maxima and averages for 
the day are given in the table. In the test made December 
17-18, 1897, cow No. 1344 showed a marked rise of tempera- 
ture, while the other three showed no response. In the test 
made April 11-12, 1898, cow No. 1343 responded, while the 
other three cows did not. Cow No. 1344 showed a slight rise of 
temperature at 4, 6, and 8 p. M., the day after injection, but she 
was observed to be in heat at this time, a condition which would 
doubtless account for slight abnormal temperatures.
