240 OP THE PILE. 



men, resin, soda,* partly united with phosphoric, 

 sulphuric, and muriatic, acid, a small portion of phos- 

 phate of lime and iron, and a variable quantity of a 

 remarkable and peculiar yellow matter. + 



385. The composition of the bile varies greatly both 

 from the proportion of its parts, particularly of the 

 albuminous and resinous, differing under different cir- 

 cumstances, and also from the addition of other con- 

 stituents, during morbid states, especially of adipo- 

 cerous substances, which give origin to most biliary 

 calculi; for these consist either of it alone, or of it 

 combined with the yellow substance just mentioned. (B) 



386. The nature of the bile is not saponaceous and 

 capable of effecting a combination between water and 

 oils, as Boerhaave supposed, but which opinion the 

 excellent experiments of Schroder, % who was formerly 

 of this university, both confirmed and extended by 

 other physiologists, § have disproved. It even decom- 

 poses a combination of those substances. || 



387. The important and various use of the bile in 

 chylification is self-evident.
