FOOD INGESTION AND ENERGY TRANSFORMATIONS. 



TABLE 107. A. L. L., May 13, 1907. Sitting. (2-hour periods.) 

 Maltose-dextrose mixture: 



Amount, 299 grams; energy, 902 cals.; from carbohydrates, 100 p. ct. 

 Basal values (May 4, 1907): CO", 51 grams; Oz, 43 grams; heat, 1 158 cals. 



1 Heat eliminated corrected for change in body- weight, but not for change in body-temperature. 

 2 Sample included amount for about 2 hours preceding the taking of maltose-dextrose mixture. 



E. H. B., May 14, 1907. The subject was given 431 grams of the 

 maltose-dextrose mixture with an energy value of 1,301 calories. An 

 examination of table 108 shows the usual striking increase in the 

 carbon-dioxide production throughout the entire experiment. There 

 was also an increase in the oxygen consumption in the first period, with 

 practically no change in the subsequent periods, and an increase in the 

 heat production in the first three periods with a slight loss in the last 

 period. The evidence clearly points towards a distinct increase in 

 metabolism as a result of the ingestion of carbohydrate. 



TABLE 108. E. H. B., May 14, 1907. Sitting. (2-hour periods.) 



Maltose-dextrose mixture: 



Amount, 431 grams; energy, 1,301 cals.; from carbohydrates, 100 p. ct. Nitrogen in urine 



1.20 grams per 2 hours. 

 Basal values (March 7 and 13, 1907): CO 2 , 58 grams; O i( 48 grams; heat, 179 cals. 



'Subject took maltose-dextrose mixture in 30 minutes. 



2 Heat eliminated corrected for change in body-weight, but not for change in body- temperature. 



J. J. ., March 4, 1910. Following the ingestion of 145 grams of 

 maltose-dextrose mixture and the juice of one lemon, with a total 

 energy value of 440 calories, positivte increases were found for the
