A STUDY OF THE INFLUENCE 



The marked increase in total solids in many of these experi- 

 ments, however, is not to be attributed, as it is in the case of 

 pure alcohol, entirely to the increased secretion ; it is rather 

 in part accounted for by the unabsorbed constituents of the 

 liquor employed. The following table, compiled from analyses 

 at hand, shows that a large portion of the total solids in the 

 gastric juices obtained may be derived from other sources than 

 the secretion itself :

E. Character of the Gastric Juice obtained by Stimulation 

 with Alcohol. The gastric juice obtained as a result of the 

 stimulating influence of alcohol and alcoholic liquors resembles 

 that ordinarily procured from gastric fistulae in its physical 

 characters ; it is a thin, colorless, or very faintly yellow fluid 

 containing occasional flocks of mucus in suspension. There 

 was no evidence of irritation or hyperaemia of the mucosa, and 

 all traces of blood were absent. After the doses used, the 

 gastric lining was of a pale or faintly pink color when removed 

 after bleeding the animal. When colored alcoholic liquors 

 were employed, the gastric contents retained the character- 

 istic coloring matter, the latter not being absorbed, while 

 the alcohol entirely disappeared. In chemical composition, 

 the gastric juice appeared somewhat more acid than that 

 ordinarily secreted. It likewise contained a larger amount of
