''Examination of Cows Used for Experiment—Twenty cows were used for the feeding experiments, and in not one of them did the most cirefiil macroscopic and microscopic search show any sign of tuberculosis of the udder except in one, and in this case a single giant cell, containing one bacillus, was found in one section, and no other indication of tuberculosis anywhere else in the udder. ''An exceedingly interesting piece of evidence as regards the hereditary nature of tuberculosis is found in the history of 19 calves born of the tuberculous cows with healthy udders. Ot these 19 calves, all killed within 6 days after })irth, not one showed any detectable evidence of tuberculosis, and a most careful search was made in all cases.
