liver (1.010-1.012). We accordingly find that the amount of solids 

 is greater in the bladder-bile than in that which may be termed the 

 hepatic bile. 



Chemical Composition. The following analyses show the gen- 

 eral chemical composition of the bile in different animals, and also 

 illustrate the differences which exist between bladder-bile and 

 hepatic bile :

Analyses of the inorganic salts have given the following results, 

 which are taken from Jacobsen and Hoppe-Seyler, respectively.
