involved in tuberculosis. In all the lunes were affected, but the 

 serous and mucous membranes, the lymphatic glands, the liver, spleen, 

 kidneys, and omentum were infected in different degrees. Conse- 

 quently, tjie transmissihility of this affection to animals being proved, 

 be insisted that its transmission to man was possible, a fact which 

 all pathologists now admit. 



TUBERCULOUS MILK. 



The recent investigations of Prof. Otto Bollinger, of the Univer- 

 sit}' of Munich, on the artificial production of tuberculosis as induced 

 by the consumption of diseased milk, have thrown additional light on 

 the subject. He claims that the milk of such animals has a pre- 

 eminently contagious influence and reproduces the disease in other 

 animals experimented on from that point of view. He believes also 

 that such milk, even when boiled^ still retains its injurious properties. 

 Further, he maintains that beyond doubt the tuberculosis of the 

 human subject, though not completely identical with that of the cow, 

 is yet strictl}' analogous to it. and that consequently the ivide preva- 

 lence of tuberculosis in the native herd, at least five per cent of 

 which are affected, is a standing danger to health of the communit3\ 



Seeing the enormous mortalit}' from consumption, more especially 

 in towns. Prof. Bollinger believes it to be of the utmost importance 

 to urge upon all classes, and particularly- upon farmers^ the absolute 

 necessity of taking eveiy possible means of stamping out the disease 

 among cattle. Meanwhile some measure of safety ma}' be secured 

 by the rigid exclusion of all diseased stock from town dairies, a 

 measure which forms a prominent feature in the programme of the 

 recently-established Associated Dairy at Munich, where all the cows 

 are constantly kept under skilled veterinary surveillance, and any 

 that may exhibit the least symptom of tuberculosis are at once 

 weeded out. 



There is eveiy reason, therefore, sa^'s Fleming, to prohibit the use 

 of milk from cows affected with tuberculosis, and especiall}' for in- 

 fants^ who mainly rel}" upon this fluid for their sustenance, and 

 whose powers of absorption are very active. Even if it did not 

 possess infective properties, its deficiency in nitrogenous elements, 

 fat and sugar, and the increased proportion of earthy salts, would 

 alone render it an objectionable article of diet. In fact, it has long 

 been known that it was liable to produce diarrhoea and debility in
