the use of milk of tuberculous cows—a matter of more than usual interest in view of the attention which is being given to the general subject of tuberculosis and its transmission. Experiments in using the milk of tuberculous cows for feeding calves at the Storrs Station have been in progress for several years. During the first two years, when the cows had the disease only in its earliest stages, the young cattle which received their milk and ran with them constantly, exhibited no signs of the disease as far as could be detected by the tuberculin test or physical examination. But the result for the next year and a half was quite different. Five calves were fed the milk of these same cows, and all five responded to the tuberculin test and proved to be diseased. The physical condition of three of the cows indicated that during the last year the disease had progressed decidedly in them. While the results indicate that the danger from the spread of tuberculosis to other animals through the milk is not always as great as has been supposed, they suggest the exercise of greater precaution in excluding from use for supplying family milk all cows in which the disease is sufficiently advanced to be detected. Experiments at a number of places have shown that the milk of tuberculous cows may be pasteurized and safely used for raising calves, but precautions should be taken to insure confining its use to this purpose.
