reaction of the contents was strongly alkaline, with no food particles, 

 and the material contained merely debris of cells, with small traces

 has reached the lower end of the small intestine. 



The following Table gives the total amounts obtained in a series 

 of experiments from the different fistulse after administration of 

 200 grm. of bread, and also the percentage amount of food-stuffs 

 which had been absorbed before the food had arrived at the level 



of the fistula in question : 



Total amounts obtained Absorbed 



from 200 grm. of bread per cent. 



Pyloric fistula .... 691 grm. 



Duodenal fistula. . . . 691,, 17-45 



Jejunal fistula .... 585 37-77
