The tests considered in this work were applied to 1812 samples of milk taken from 54 cows. The tests showed a much more frequent occurrence of abnormal milk than was expected.

The study herein reported deals with the occurrence of abnormal milk in the college dairy herd and a comparison of the results of various tests including the brom thymol blue test, the catalase test, the leucocyte count and the examination for long-chain streptococci.
