CONCLUSION 



1. Gastric juice in healthy normal individuals shows no 

 specific curve, but types of cur\'e can be found which are 

 named isosecretory and hypersecretory. 



2. The pathological significance arises when a curve 

 shows any marked deviation from the recognized standard. 



The most typical curves have been chosen from a group 

 of one hundred fifteen cases examined. It has not been my 

 purpose to offer a complete interpretation in this study of 

 acidity curves, so much as it has been my aim to show how 

 they serve as a means of aiding in diagnosis, and to repre- 

 sent some of the possibilities open for advanced study dur- 

 ing a "Liberal Arts Course."
