in a bad physical condition when slaughtered in November, 
19Oo.

SUMMARY OF THE RESULTS OF FEEDING THE MILK OF THE 
COWS TO CALVES. 
During the larger part of the four years that these tubercu- 
lous cows were at the Station the milk of some or all of them 
was fed to calves. In some cases the calves fed were the off- 
spring of the tuberculous cows, while in other cases they were 
from cows which careful tests had indicated were free from 
the disease. In some cases the calves were allowed to associ- 
ate with and to suckle their dams, while in other cases they 
were separated from the cows and were fed from a pail.
