E. DIGESTION AND ABSORPTION. 



As intimated in the introduction it is taken for granted 

 that by the time a medical school has found the conditions 

 propitious for the establishment of a laboratory of experi- 

 mental physiology, the whole province of chemical physiol- 

 ogy will have been occupied by the department of 

 chemistry as a legitimate growth of that department. 



The American laboratory of experimental physiology 

 will present, almost exclusively, the physical problems of 

 physiology. But even where such are the conditions it 

 may seem advisable to introduce into a course of lectures 

 or recitations on the physiology of digestion a series of 

 demonstrations. 



The following exercises in the chemistry of digestion 

 and the physics of absorption may be given either as dem- 

 onstrations or as laboratory exercises. 



This chapter is not intended as a substitute for any of 

 the excellent treatises now used in medical schools, but 

 rather as a supplement to them. 



It will be taken for granted that the student has had at 

 least one year of chemistry before he enters upon this 

 course. 



To give the course which is outlined one will need the 

 following appliances, apparatus and reagents.
