410 LIQUID PARTS OF ANIMALS. 



Berzelius analyzed bile in 1808, and gave the result in the se- 

 cond volume of his Animal Chemistry* According to this ana- 

 lysis, the constituents of the bile are as follows : 



Water, . . 908-4 



Biliary matter, . . 80-0 



Albumen, . ;. . 3-0 



Soda, . . tt *i". 4-1 



Phosphate of lime, . O'l 



Common salt, . . 3 -4 



Phosphates of soda and lime, . 1*0 



1000-0 f 



He afterwards made some corrections on his analysis, and in 

 his Traite de Chimie, (vii. 189), gives the constituents of bile as 

 follows : 



Water, . . . . 904-4 



Biliary matter, (including fat), lj;f ... . 80-0 



Mucus of gall-bladder, . . ; r , 3-0 



Extract of meat, common salt, and lactate of soda, .,^ f 7-4 

 Soda, .... 4-1 



Phosphates of soda and lime, trace of substance insoluble 1 , , 

 in alcohol, ;;> . . / 



1000-0 



It is obvious that the biliary matter of Berzelius and the pi- 

 cromel of Thenard constitute one and the same substance. 



Dr Prout analyzed the bile in the same way as Berzelius, and 

 obtained similar results. 



Tiedemann and Gmelin published their work on digestion in 

 1825. They made a great many experiments on ox-bile, and 

 likewise on the bile of other animals. From ox-bile they extract- 

 ed no fewer than twenty-three different substances, which they 

 distinguished by the following names : 



1. An odorous principle. 



2. Cholesterin or biliary tallow. 



3. Biliary resin. 



4. Biliary asparagin or taurin. 



5. Picromel. 



* Djurkemie, ii. 48. 



t Berzelius does not mention the animal whose bile this is an analysis of, I 

 presume it was ox-bile.
