 digestive properties of gastric juice, it had occurred to him to 

 collect it by means of a cannula, a sort of silver tap which he 

 adapted to the stomach of live dogs. A Berlin surgeon, M 

 Dieffenbach, who was staying in Paris, expressed a wish to 

 see this application of a cannula to the stomach. M. Pelouze 

 the chemist, had a laboratory in the Eue Dauphine ; he offered 

 it to Claude Bernard. A stray dog was used as a subject for 

 the experiment and shut up in the yard of the house, where 

 Claude Bernard wished to keep a watch on him. But, as the 

 treatment in no wise hindered the dog from running about, the 

 door of the yard was hardly opened when he escaped, cannula 

 and all.
