time given represents the experimental period. The food was usually taken less than 

 half an hour before the beginning of the experiment. See tables 101 to 122 for details.

Unlike the experiments with sucrose, the maltose-dextrose experi- 

 ments did not show the highest increment with the largest amount, 

 as the greatest increase (28 per cent) was found with only 145 grams. 

 The first two experiments recorded with the maltose-dextrose mixture 

 are comparable in that the amounts of carbohydrate ingested are 

 approximately the same and show an average increment of 13 to 14 

 per cent. In one of these experiments, that with Dr. R., the maximum 

 effect was not observed until 4j to 6 hours after the food was taken. 

 As this subject was particularly satisfactory from the standpoint of 

 technique, we have no explanation for this long-delayed action in secur- 

 ing the maximum value. Two other experiments, which were made 

 with approximately 300 grams of the sugar mixture, do not give very
