Summarising the facts noted after inoculating members of the 

 Gallinacese with human tuberculosis, the results are as follows : 



Thirty-two fowls were inoculated with tuberculous material derived 

 directly from man, or having passed through other animals ; on post- 

 mortem examination five showed visceral granulations ; in all inocula- 

 tions tuberculosis had been produced, i. e. tuberculosis resulting from 

 human, and not from avian bacilli. Even though objection might be 

 made regarding the second series of experiments, no doubt seems 

 possible concerning the fowl in which the granulations proved inocu- 

 lable to the guinea-pig and to another fowl. In these cases the bacillus 

 had preserved its original characteristics, and the nature of the infection 

 appeared to us absolutely proved. 



Inoctdation with Bovine Tuhercidosis. — We were not content to 

 inoculate with human tuberculosis alone, but utilised tuberculous 

 material from different mammals, and particularly from animals of the 

 bovine species ; such a test appearing more important on account of 

 the doubts which have recently been thrown on the identity of 

 pulmonary tuberculosis in animals and human tuberculosis. Fowls 

 remained unaffected whilst the disease was transmitted to the rabbit, 

 guinea-pig, and cat.
