on to a skim-milk diet, and was placed in the College herd, with 
the intention of raising the calf for dairy purposes. Calf C 
was tested with tuberculin July 30-31, September 27-28, 
and December 17-18, 1897. During the summer of 18098 the | 
calf was kept at pasture with other young stock, and made a 
vigorous growth. It was tested with tuberculin December 
22-23, 1898, but gave no response. It is now nearly two years 
old, and is a large, vigorous animal. 
Feeding calf D with milk of cow No. 1344. — This calf was 
dropped by a vigorous grade cow November 29, 1SO7 Mee 
dam was tested with tuberculin March 3-4, 1897, but gave no 
response to the test. The calf was first subjected to the tuber- 
culin test December 17-18, but gave no response, \G algae 
was again tested April 11-12, 1898, but did not respond. This 
calf had all the milk produced by cow No. 1344 (about 10-12 
pounds daily) from early in December, 1897, up to the present 
time (February, 1899). The last tuberculin test was made 
December 22-23, 1898, with no response. Thé animamias 
made a rapid growth and is a large, vigorous yearling at the 
present time. 
From the records just given of the feeding of these four 
animals, it will be seen that each consumed the milk of a sep- 
arate cow for periods varying from three months to a year and 
four months, and that in no case was there any sign of the 
disease having been contracted during these feeding periods. 
One animal (B) did respond to the tuberculin test nearly six 
months after the feeding period with milk was ended, but from 
the mild form in which the disease existed, and its location, it 
seems very doubtful if the disease was contracted through the 
milk. These tests point to the conclusion that the milk is not 
as dangerous a source of infection as has been commonly 
supposed. 
As has already been stated, three of the cows, Nos. 1337, 
1341, and 1343, produced calves in August and September, 
1898. All of the calves have been fed the milk of their dams 
since being dropped, down. to the present time (February, 
1899). 
Feeding calves E and F.— Calf E was a large heifer calf, 
dropped by cow No. 1341, August 11, 1808, and calf F was a 
bull calf, dropped by a grade cow in the College herd. This 
cow was supposed to be healthy, but within three months after
