These experiments show that the distribution of cholera vi- 

 brios in the alimentary canal of experimental cholera carriers 

 fed on ox bile was more extensive, the elimination of cholera 

 vibrios in the faeces was more constant, and the cholera vibrios 

 were present in the alimentary canal in larger numbers than 

 in the case of the carriers that received no bile.
