 SECT. XXIV. 



OF THE PANCREATIC JUICE. 



363. THE chyme, after passing the pylorus, under- 

 goes new and considerable changes in the duodenum* 

 a short but very remarkable portion of the intestines, 

 before the nutrient chyle is separated. To this end, 

 there are poured upon it various secreted fluids, the 

 most important of which are the bile and pancreatic 

 juice. 



364. Of these we shall treat separately, beginning 

 with the pancreatic fluid, because it is closely allied 

 both in nature and function to the saliva and gastric 

 juice already mentioned. 



365. Although it is with difficulty procured pure from 

 living and healthy animals, all observations made in 

 regard to it establish its close resemblance to the saliva. 

 At the present day, it would scarcely be worth while to 

 mention the erroneous hypotheses of F. Sylvius f and 

 his followers R. De Graaf, ^ F. Schuyl, and others, 

 respecting its supposed acrimony, long since ably re- 

 futed by the celebrated Pechlin,|| Swammerdam,* * and
