186 STORRS AGRICULTURAL EXPERIMENT STATION. 
The general conditions and results of this test were as fol- 
lows: ‘Three calves, while at pasture, were each fed the milk 
of a separate cow. Calf L, was fed the milk of a cow in a 
slightly diseased condition, and at the end of a feeding period 
of about four and one-half months, and again five months 
later, failed to respond to the tuberculin test. Calf M was fed 
the milk of a badly diseased cow, and at the end of a feeding 
period of four and one-half months failed to respond to the 
tuberculin test; but when examined two months later, after 
having died apparently from poisoning, did show a slightly 
tuberculous condition. Calf N was fed the milk of a badly 
diseased cow for a period of about four and one-half months, 
when it failed to respond to the tuberculin test, and did not 
respond to a similar test five months later. Calves L and N 
were sent to pasture when about one year old and appeared to 
be in a vigorous state of health. 
CONCLUSION. 
The results of these experiments with tuberculous cows and 
the use of thetr milk for feeding calves coincide with the general 
results of European observations, and indicate that the danger 
of the spread of tuberculosis through the milk of diseased animals 
zs not so great as has often been supposed. In the earlier stages 
of the disease, and when the udder ts not affected, the danger 
from the use of the milk appears to be limited. But when the 
udder ts affected, or when the disease ts so far advanced as to be 
indicated by outward signs or marked physical symptoms, the 
infectiousness of the milk ts increased, and the danger in using tt 
as food for man or animals ts greater. 
From what has been said, however, it is not to be understood 
that the farmer may neglect any case of tuberculosis tn his herd if 
zt zs not in the advanced stages, or tf the udder of the cow ts not af- 
fected. Asa matter of fact, it ts practically impossible for him to tell 
when any animal that reacts to tuberculin may acquire tubercu- 
losis of the udder. There ts danger enough in the fact that the 
cows may acgutre the disease from one another at all, no matter 
how likely or unlikely they may be to do so. Therefore, tf the 
farmers do not want their dairy industry menaced and perhaps
