insists very strongly upon the danger arising from the use of 

 tuberculous milk and flesh. He and others have inquired closely 

 into these subjects, and, especially in examination of milk of 

 tuberculous cows, they have found Koch's bacillus tuberculosis ; 

 and when tests have been made with these bacilli, tuberculosis 

 has resulted. With reference to tuberculous flesh I will intro- 

 duce here the following quotation in which he refers particularly 

 to this branch of the subject : — " There can be little doubt that 

 in those cases where the disease is localised to any one of the 

 viscera at the time of the death of the animal, there is little 

 danger to be anticipated frooi eating the well-cooked flesh from 

 other parts of that animal ; and if we could be absolutely 

 certain that the localisation was complete, all would be well." 

 Even in cases where the flesh is taken from animals in advanced 

 stages of tuberculous disease there would be a certain proportion 

 of cases in which no evil results would follow, and one observer 

 who made sixty-two experiments with such flesh boiled for ten 

 or fifteen minutes, found tliat only 35-5 per cent of the inoculated 

 animals became tuberculous. Even in cases of generalised 

 tuberculosis Nocard failed in thirty-nine out of forty cases to 

 transmit the disease by means of raw muscle-juice injected into 

 the peritoneal cavity of guinea pigs, but he- succeeded in the 

 fortieth. Other observers, however, have been more successful, 

 and in two rabbits I was able to produce tuberculosis by injec- 

 tion into the peritoneal cavity of the raw juice expressed from 

 the intercostal muscles of a tuberculous cow after all tubercu- 

 lous pleura had been carefully "stripped"; whilst the juice 

 taken from the muscle of the thigh injected into two other 

 rabbits was perfectly innocuous. The danger of infection by 

 the consumption of meat from tuberculous cows may have 

 been much exaggerated, but that there is a very appreciable 

 danger must most certainly not be lost sight of by our medical 

 officers of health, and the Veterinary Inspectors of the Board of 

 Agriculture. With reference to the danger which arises, 

 especially to young children, from the use of unboiled milk, the 

 same authority is equally explicit. The alimentary canal is an 

 important channel of infection. The evidence of this lies in 

 experiments which are regarded as satisfactory, and " in the 

 ulceration of the intestine that is so frequently met with in
