teed and certified milk and excepting the milk which was 

 used for cooking and for commercial purposes, would be 

 pasteurized. They were convinced that what he had set 

 forth was the solution of the problem so far as New York 

 City was concerned. The conditions in New York City 

 were, of course, somewhat different from what they were 

 in smaller communities where the milk was derived from a 

 small area; but they felt convinced that under the conditions 

 existing in New York it was only in the way he had 

 described that a safe milk could be supplied. 



THE ADMINISTRATIVE CONTROL OF 

 THE MILK SUPPLY, WITH SPECIAL 

 REFERENCE TO TUBERCULOSIS. 



BY J. M. BEATTIE, M.D. 



Professor of Bacteriology in the University and Bacteriologist to the City of Liverpool. 



So much evidence has now been accumulated as to 

 the relation of a tuberculous milk supply to tuberculosis 

 in children, that it is not necessary to give more than 

 the merest outline of the statistical evidence in order to 

 convince even the most sceptical of the importance 

 and the gravity of the problem with which it is my 

 privilege to deal at this Congress. 



It is generally agreed that the tuberculous lesions 

 which are due to the bovine bacillus are more par- 

 ticularly those situated in the cervical glands and in 

 the intestines and mesenteric glands the former 

 infected by way of the tonsils and adenoids of the 

 nose and pharynx, the latter by the direct ingestion 

 of foods containing the bacillus of tuberculosis. 



It is somewhat difficult to get accurate statistics 

 on these points, but the following table of an analysis 

 of 1,042 cases of tuberculosis in adults and in children 

 by Park and his colleagues [i] is sufficient to show 

 the importance of the, bovine bacillus in producing 

 human disease :
