For the sake of comparison these data are contrasted in the 

 following table (see p. 99). 



These results afford tangible evidence of the stimulating 

 action of the liquors examined, as shown in the increased 

 volume of gastric contents, accompanied by increase in acidity. 

 That alcohol is an important factor in the production of these 

 phenomena seems certain. Contrast, for example, Experiment 

 XX with XXII, which differs only in the absence of the
