ANALYSES OF HUMAN BILE, 



[BOOK II. 



* The acids are here given. 



In these analyses the fact is brought out very distinctly that, in 

 the bile of man, glycocholic acid preponderates very greatly over 

 taurocholic acid, which may even be altogether absent (see Jacobsen's 

 analysis). The same fact results from the analyses made, by the most 

 competent observers, in the case of bladder bile. 



analyses of The following exhibit the method of analyses of 



bladder-bile in 5 samples of human bile (taken post mortem from the 

 the human gall-bladder) made by Hoppe-Seyler in 1872 1 . 



Mucin in 100 parts 1'29 



Other organic matters insoluble in alcohol 0*14 



Sodium taurocholate 0*87 



Sodium glykocholate 3'03 



Soaps 1-39 



Cholesterin 0'35 



Lecithin 0'53 



Fats 0-73 



Phosphate of iron 0'0166 



Ratio of sodium glykocholate to sodium taurocholate is as 3*4 : 1. 



Bile of the Dog. 



The following analyses made by Hoppe-Seyler 2 illustrate the 

 composition of the bile of the dog. In this animal the bile never 

 contains glykocholic acid.
