guinea-pig under treatment the seat of inoculation in the flank showed 

 a large tuberculous ulcer. 



Of the survivors, those under treatment, equally with the controls, 

 gradually lost weight ; in no case where an ulcer had developed in the 

 flank after inoculation did it heal. 



All the guinea-pigs were killed on the 15th October, and all showed 

 tuberculous lesions. In many of those treated with small doses of 

 vanadine the lesions were only a little less numerous or less diffused 

 than in the others. 



MM. Laran and Hallion obtained very interesting results by treat- 

 ing guinea-pigs, rendered tuberculous by subcutaneous inoculation, 

 with very small hypodermic injections of vanadic acid. Under the 

 influence of these injections M. Laran has " often seen healing of 

 tuberculous ulcers in animals. In a guinea-pig thus inoculated and 

 treated by vanadic acid death was postponed for a year and a half. 

 M. Hallion, who studied the pulmonary lesions histologically, noted 

 "very marked fibrous transformation."
