in its operation upon animals fed either with the milk or with 

 dairy produce derived from it. No doubt the largest part of the 

 tuberculosis which man obtains through his food is by means 

 of milk containing tuberculous matter." 



82. "Provided every part that is the seat of tuberculous 

 matter be avoided and destroyed, and, provided care be taken to 

 save from contamination by such matters the actual meat sub- 

 stance of a tuberculous animal, a great deal of meat from 

 animals afi'ected by tuberculosis may be eaten without risk by 

 the consumer." 



83. "Ordinary processes of cooking applied to meat which 

 has got contaminated on its surface are probably sufficient to 

 destroy the harmful quality. They would not avail to render 

 wholesome any piece of meat that contained tuberculous matter 

 in its deeper parts. The boiling of milk, even for a moment, 

 would probably be sufficient to remove the very dangerous 

 quality of tuberculous milk." 



39. " There is always a difficulty in making sure of th9 

 absence of tuberculous matter from any part of the carcase that 

 shows evidence of tubercle elsewhere." 



Dr. Sims Woodhead is reported to have stated that a man 

 might eat a sufficiently large quantity of tubercular meat con- 

 taining tubercle at one meal to induce tuberculosis. 



Bovine tubercular matter is much more virulent to animals 

 generally than human tubercular matter. 



Dr. Sydney Martin in a contribution to the " Journal of 

 State Medicine" says: — The parts of the body which are 

 affected by the disease after infection are very varied in indi- 

 vidual cases, and this variability, which in former times led to 

 great misconception as to the nature of the disease (which was 

 described as arising in the body, for example), led undoubtedly 

 to a delay to the acceptance of tuberculosis as an infective 

 disease. There are cases, for example, which are readily 

 explained, such as primary pulmonary tuberculosis, and primary 

 intestinal tuberculosis, in the former of which the infective 

 material is evidently inhaled, in the latter of which the material 

 is swallowed, and produces ulceration of the small intestine, 

 affecting secondarily the mesenteric glands. There are other 

 cases of tuberculosis which are not so easily explained. These
