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

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

 food-stuffs is thus practically complete by the time that the food 

 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 fistulae 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 



Ileum fistula .... 412 67-65 



Caecal fistula .... 80 94-34
