250 STORRS AGRICULTURAL EXPERIMENT STATION. 
1344 (10-12 pounds daily) during the past winter, and, in addi- 
tion, a small amount of dry grain feed and hay. It has made 
a rapid growth and appears vigorous and healthy. 
The following statement by the College Veterinarian is 
appended to this article in order to show the present condition 
of the cows as far asa physical examination will indicate, It 
was made May 8, 1808, while this Report is being printed: 
It is a fact well recognized, that bovine tuberculosis, unless well advanced, is 
one of the most difficult diseases to diagnose upon a physical examination. 
Of the seven animals examined four are the Devon cows that have been tested 
and found to respond at one time or another, three (A, B, and D) are young 
bulls that have been fed with the milk of the cows. The calves have not reacted 
to the tuberculin test and a careful physical examination fails to reveal any indi- 
cations that they have tuberculosis. 
Of the four cows that have responded to the test, No. 1337 presents no symp- 
toms of tuberculosis. She is in good flesh, and looks well. Her temperature 
was 102° F., respirations full and at the rate of twelve per minute. 
Cow No. 1341 is thinner in flesh than any of the others and seems to be 
affected -with a slight but chronic looseness of the bowels. Her temperature 
was 102.2” F., and respirations twelve per minute. 
Cow No. 1343 is rather fat. She is troubled with a chronic cough, and aus- 
cultation indicates that the anterior (cephalic) lobes of the lungs, especially the 
right, are tuberculous. Her temperature was 102.6° F., and respirations are 
twenty-two per minute. Cows No. 1337, 1341, and 1343 are pregnant. . 
Cow No. 1344 is in good flesh. Temperature ror.8° F., and respirations 
fifteen per minute. Nothing abnormal could be detected upon a physical exam- 
ination. No enlarged glands could be detected in any of the animals examined. 
Of the four cows that have at some time responded to the test, Nos. 1337 and 
1344 show no symptoms of the disease having developed. In No, 1341 the 
chronic looseness of the bowels may be considered as a suspicious symiptom of a 
tubercular affection of the digestive tract. In No, 1343 the physical symptoms 
indicate tuberculosis of the lungs. 
It must be remembered that all of these animals have had good care and 
attention and have not been exposed to conditions or circumstances that would 
cause the disease to develop.

DEDUCTIONS. 
Our definite knowledge of tuberculosis is of recent origin and 
is limited at the best. We know comparatively little regard- 
ing the conditions which favor its spread and development, 
either among animals or man. Most of all are we lacking in 
definite knowledge of the dangers of the disease to mankind 
from the bovine race. New experiments and new discoveries 
may so modify our views as to make present conclusions of
