Experiment 6. Guinea-pig inoculated on the gth July, 1894, with 

 part of a horny cutaneous growth from the right side of the head 

 (Case 6). The guinea-pig died on the 30th August, i. e. at the end of 

 fifty-seven days. Autopsy showed numerous granulations on the peri- 

 toneum, in the liver, spleen, and lungs. 



Experiment 7. On the 28th September, 1895, three fowls were 

 intra-peritoneally inoculated with experimental tuberculosis of the 

 parrot (Experiment 2). One was killed on the 24th November follow- 

 ing ; another on the 5th December ; the third on the 5th March, 1896. 

 No change whatever was found on post-mortem examination. 



To sum up, ten guinea-pigs inoculated with tuberculous material 

 obtained directly from the parrot, or having passed through other 

 guinea-pigs, died after periods varying between 23 and 144 days, that 

 is after an average period of sixty-seven days. In all, post-mortem 

 examination showed intense and generalised lesions. 



Of four rabbits inoculated under the same conditions only one died 

 spontaneously at the end of 378 days. The others were killed between 

 the 117th and the 359th day. In spite of this much longer survival, 

 which rendered the average period 226 days, we only found on post- 

 mortem examination a few discrete granulations on the peritoneum and 

 in the liver.
