in its earlier stages. One object in view in the experiment was 
to study the effect of the milk of slightly diseased cows when 
fed to healthy calves.

* Through the courtesy of the former Secretary of the State Cattle Commission we 
are able to publish the temperatures obtained in the tuberculin tests made prior to 
the arrival of the cows at the Station. ‘These tests were made by. Dr..L,...J. Storrs: 
Care of the Cows, and Tuberculin Tests after they were taken 
wn charge by the Station.—When the cows were brought to the 
Station they were placed in high, light, and airy stables afford- 
ing about 1,500 cubic feet of air space per cow, although later 
three calves occupied the same stables with the cows. Adjoin- 
ing the stables was a yard about one-half acre in area, where 
the animals could exercise. In mild weather they occupied 
the yard most of the day. No special treatment for the dis- 
ease was attempted, but good care and feed were afforded at 
all times. Plans were made whereby the animals could be sub- 
jected to the tuberculin test from time to time. ‘These tests 
were made wide apart (from two to four months), with the 
thought that perhaps the animals would not be as likely to 
become immune* to the effects of the tuberculin, and thus 
later fail to respond. ‘The animals, however, failed to respond 
to later tests, although it is, perhaps, doubtful if this can be 

* By immune or immunity, as here used, is meant a supposed power of resistance 
by the animal to the ordinary effects of tuberculin, caused by repeated injections, so 
that no rise of temperature results.
