CUTANEOUS REACTION IN LEPROSY. 327 



Pift)^ lepers were vaccinated with these extracts, a control vaccination 

 with the extract of skin from the cholera case being made in each 

 instance. In two or three cases there was a doubtful reaction, but 

 otherwise the vaccinations were in all respects like the controls. Further 

 attempts will be made to secure a more concentrated extract of the leprosy 

 bacilli. Owing to the low resistance of the tissues of lepers, it was not 

 thought advisable to use the ophthalmo-reaction until the cutaneous re- 

 action had been given a thorough trial. 



I wish to thank Doctor ISTewberne for the courtesies extended to me 

 at the San Lazaro Leper Hospital.
