TUBERCULOUS COWS AND USE OF THEIR MILK. 107 
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 
temperature was 102.20 F., respiration 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 tem- 
perature was 1020 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 101.80 F., and respira- 
tions 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 re- 
sponded to the test, Nos. 1337 and 1344 show no symptoms of the dis- 
ease 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 tuber- 
culosis 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. 
Report of the Veterinarian, Feb. 7, 1899. —Of the four Devon cows 
examined, No. 1337 does not seem to be in as thrifty condition as she 
ought to be, considering her care and feed. No. 1341 is not in as thrifty 
condition as No. 1337, and would probably be condemned as tuberculous 
on a physical examination. Nos. 1343 and 1344 are in excellent condi- 
tion, physically, both being rather fat, and are looking well. The only 
evidence of disease is found in No. 1343, her respirations not being as 
full ahd deep as they should be normally. No cough was noted in any 
of the animals.

FEEDING CALVES WITH THE MILK OF TUBERCULOUS COWS. 
Soon after the cows were brought to the Station, plans were 
made for feeding their milk to calves from healthy cows, and in 
some cases to their own offspring. These experiments have 
been continued for a little over two years. In some cases the 
calves have been allowed to suck their dams, while in others
