Thj^mol 1-3,500 applied for fifteen minutes had the unique effect 

 in some of the experiments of destroj'ing the amoebse while exercising 

 only a moderate effect on the cholera spirilla. 



There is no specific treatment for amoebic dysentery, but, if the 

 test-tube results detailed above are a fair index of the behavior of 

 the substances in the actual local treatment of the disease, the 

 clinician can add to his therapeutic armamentarium a few more 

 agents of a value equal or superior to quinine. Such a choice will 

 be appreciated by physicians practicing in the Tropics when they 

 encounter patients intolerant of quinine, or otherwise failing to 

 benefit by its local action.
