several parts of the body, but these tests failed to show any 
sign of the disease or of *the tuberculosis germs. Cow No. 
1337 produced a vigorous heifer calf April 5, 1897. ‘This calf 
suckled its dam for about six months and was then placed in 
the College herd and reared for dairy purposes. All four cows 
gave a fair flow of milk from the time of calving until they 
went dry preparatory to calving again. During the second 
year (1898) that the cows were under observation Cow No. 
1337 remained in a good condition of flesh and appeared to be 
in vigorous health. She dropped a well developed calf in Sep- 
tember, 1898, which was allowed to suckle its dam for about a 
year. Cow No. 1341 produced a well developed calf in August, 
1898, and seemed to be in a good state of health throughout 
the following winter. Cow No. 1342 became quite fat during 
the early part of 1898. She dropped a rather small calf in 
August, 1898. This cow was considerably thinner than usual 
for three months after calving, but soon after that began to 
gain in flesh. Later in the fall of 1898 cow No. 1343 was 
noticed to have a persistent cough, which continued through- 
out the winter. Cow No. 1344 remained farrow during 1898, 
although she continued to give a good flow of milk. During 
the fall of 1898 she gained in flesh and appeared to be in a 
healthy, vigorous condition. 
During the year 1899 cow No. 1337 remained in a vigorous 
state of health, producing a healthy calf in December of that 
year. The calf appeared to be vigorous and strong at birth, 
but was soon after attacked by scours and died in a few days. 
Cow No. 1341 remained in a fair state of flesh and continued 
to give a good flow of milk till July, 1899. At that time, 
while being fed green oats and peas, she was attacked by 
scours and began to ‘‘run down”’ rapidly. She ceased giving 
milk for a short time, but when placed on dry feed began to. 
regain her flesh and milk flow. This cow remained in a fair 
state of health during the fall of 1899, although she had a 
somewhat irregular tendency to looseness of the bowels. Cow 
No. 1343 continued to givea fair flow of milk during the spring 
and summer of 1899, although she was not as fat as during 
1898. The cough which was first noticed late in the fall of 
1898 increased in severity during the following winter. Dur- 
ing the spring of 1899 she coughed badly after eating dry feed.
