Seven of the seven experimental cholera carriers fed on bile 

 were found positive from sixteen to thirty-five days after the 

 inoculation, while only three of the six control carriers were 

 found to harbor cholera vibrios during the same period of time. 



These experiments show clearly that the increased flow of bile 

 does not further the disappearance of the cholera vibrios from 

 the gall passages and from the intestine. On the contrary, it 

 seems strongly to indicate that the administration of bile, a 

 cholagog "par excellence," tends to prolong rather than to 

 shorten the duration of the state of cholera carrier.
