THE SECRETION OF THE BILE. 



271 



QUANTITY OF BILE AND BILE-SOLIDS SECEETED BY THE DOG 

 (PER KGRM. OF THE BODY- WEIGHT IN 24 HOURS). 



It will be gathered from a study of the results exhibited in the 

 above table that the quantity of bile secreted by the dog is subject 

 to remarkable variations. In these experiments, for the most part, 

 the quantity of food consumed by the animal has been left out of 

 consideration. 



Some relation will probably be discovered to exist between the 

 amount of the solid matters of the bile and that of the products of 

 the tissue waste of the organism as a whole, but the observations 

 hitherto made have neither been directed, nor been adequate, to the 

 elucidation of such a relation. 



In the first 1 of the subjoined tables are exhibited 

 the average quantities of bile and bile-solids obtained 

 in the case of the dog, cat, sheep and rabbit, by 

 Bidder and Schmidt, and in that of the guinea-pig by 

 Friedlander and Barisch 2 . 



Heidenhain has expressed in a convenient tabular 

 form (see the second of the subjoined tables) the 

 results of calculations based upon existing data which
