TUBERCULOUS COWS AND USE OF THEIR MILK. 105 
fair flesh during the winter of 1896-7, and was dry about three 
months. She dropped a strong heifer calf on April sth. From 
birth till September 2oth the calf sucked its dam. During this 
time the cow seemed a little thin in flesh, although not notice- 
ably so considering her condition of milk. This cow gained 
in size and flesh during the winter of 1897-8. She was kept 
at pasture while dry, from the latter part of June until Sep- 
tember 15, 1898, at which time she dropped a strong, vig- 
orous heifer calf. The calf has sucked its dam from birth to 
the present writing (February, 1899). For the first two months 
after calving the cow seemed a little thin in flesh, but at the 
present time she isin good order. This cow has had no cough 
since she was brought to the Station, and has looked strong 
_and vigorous, eating well and appearing in good health at all 
‘times. 
Cow No. 1341. This cow was pregnant at the time she was 
brought to the Station in November, 1896. The exact time 
that she was due to calve could not be ascertained, but it was 
supposed that she would calve in March or April, 1897. She 
was dry for about two months, and dropped a dead calf March 
2, 1897. The foetus was well covered with hair, and appeared 
to be premature by about one month. A careful physical ex- 
amination of the calf, made by the College veterinarian, failed 
to show the presence of tuberculosis, and cultures made from 
several sections of the body failed to reveal the germs of tuber- 
culosis. The cow was quite thin in flesh for about three months 
aiter calving, but gained slightly during the following sum- 
mer. She was quite a heavy milker, and this fact may account 
in part for her thinness in flesh. During the winter of 1897-8 
she gained in flesh, and in April, 1898, appeared in fair physical 
condition. At times during the winter she had a chronic 
looseness of the bowels, but no cough was observed. This 
cow was dry from about the middle of June until the time of 
calving, August 11, 1898, and during this period she was kept 
at pasture. For about a month after calving she seemed to 
be running down in flesh, but soon began to gain, and by the 
time the cows were placed in their winter quarters she was in 
fair flesh. She has produced quite a heavy flow of milk ever 

since dropping her last calf. At the present time (February, 
1899) she seems to be a little thin in flesh, although no cough 
has been noticed. She continues to eat well, and appears in 
a fair state of health.
