TUBERCULOUS COWS AND USE OF THEIR MILK. BS: 
flesh, and at the present time (May, 1900,) seems quite thin 
and shows the position of her ribs plainly. Previous to the 
fall of 1899, cow No. 1344 was not noticed to have any cough, 
but during the past winter she has coughed quite vigorously. 
The lame leg has been quite badly swollen about the stifle 
joint, and this lameness has caused her considerable inconve- 
nience in moving about. She was, however, less lame after 
warm weather came, and she was able to exercise freely in the 
yard. This cow was tested with tuberculin June 2-3, and 
December 1-2, 1899, and again March 19-20, 1900, but did 
not respond to any of these tests. 
PHYSICAL EXAMINATIONS. 
On May 8, 1898, and February 7, 1899, Prof. N. S. Mayo, 
the College Veterinarian, made physical examinations of the 
animals. ‘The report of these examinations were given in the 
article on the subject in the Report of the Station for 1898. 
They are repeated here for comparison with the report of the 
examination made by the same veterinarian, May 26, 1900. 
These reports are as follows: 
Report of the Veterinarian, May 8, 18g8.—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 
indications that they have tuberculosis. 
Of the four cows that ‘have responded to the test, No. 1337 presents no 
symptoms of tuberculosis. She is-in good flesh and looks well. Her tempera- 
ture was 102.2° 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° F., and respirations twelve per minute. 
Cow No. 1343 is rather fat. She is troubled with a chronic cough, and 
auscultation 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 Nos. 1337, 1341, and 1343 are pregnant. 
Cow No. 1344 is in good flesh. Temperature 101.8" F., and respirations 
fifteen per minute. Nothing abnormal could be detected upon a physical 
examination. 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 
symptom of a tubercular affection of the digestive tract. In No. 1343 the 
physical symptoms indicate tuberculosis of the lungs.
