course of the lymphatics, right up to the arm pit, and 

 that after suffering pretty severely from the disease for 

 several weeks a cure was effected. 



Another case is reported from South Africa, where 

 a man attempted to inoculate himself, but failed. 

 Personally I have conducted both the surgical treat- 

 ment and post-mortem examinations of several hundred 

 animals affected with the disease, under various con- 

 ditions, and have from time to time run considerable 

 risk of becoming inoculated, but have so far escaped 

 the disease. 



Busse in 1895 observed a saccharomyces analogous 

 to the cryptococcus of Rivolta in a sarcomatous growth 

 on the tibia of a woman, but the further investigation 

 of the case tends to prove that this was some other 

 organism. 



However, although to my knowledge there is no 

 authentic information forthcoming of a human being 

 ever becoming infected with the disease, and that 

 accidental inoculation appears to be unlikely, I think 

 that until something more definite is known about it 

 the risk of man contracting the disease is, although 

 remote, always to be carefully considered and guarded 

 against in dealing with this disease. 



Resistance of the Virus 



According to Rivolta and Micellone, it may be 

 destroyed in a few minutes at a temperature of 80^ C, 

 but that it resists the action of a 5 per cent, solution 

 of carbolic acid. My own experience is, that in the 

 treatment of the cases, carbolic acid is practically 

 useless, and that the only thing that can be relied on to 

 destroy the organism is perchloride of mercury, and of 

 this a solution of not less than i in 250 is recommended.
