INGESTION OF MIXED DIETS. 



319 



of 6 hours continued from 7 h 15 m a. m. to I h 15 m p. m.; the subject 

 was quiet throughout the whole period. 



The basal values used for comparison were obtained on April 19 to 

 20, 1906, and on April 6, 1906. The lengths of the first and third 

 periods of measurement do not correspond exactly to those of the food 

 experiment, but the values have been computed to the same basis. 

 The first fasting period contained less muscular activity than the 

 corresponding food period, as the subject ate no food and retired 

 12 minutes after the beginning of the period. 



An examination of the results given in table 244 shows that the heat 

 production in the 16 hours of the food experiment increased 281 calories 

 over that in 16 hours of fasting, representing a percentage increment 

 of approximately 25 per cent. Furthermore, in the last 6 hours of the 

 experiment there was a metabolism measurably above that of the 

 control period, showing a prolonged after-effect of the food ingestion. 



TABLE 244. A. L. L., April 6-7, 1906. 



Heavy supper (mixed diet): 



Amount, 1,273 grams; nitrogen, 8.87 grams; total energy, 2,442 cals. 



Fuel value: Total, 2,364 cals.; from protein, 10 p. ct.; from fat, 53 p. ct.; from carbohydrates, 

 37 p. ct. 



Subject retired at 9 h 12 m p. m. on night of April 19-20 and at lO^O 01 p. m. on April 6-7. Pre- 

 vious to these times there was the activity connected with weighing and the preparations for 

 retiring; on the night of April 6-7 subject went to the food aperture 3 times and opened it about 

 15 times. 



2 Computed to basis of 9 hours, i. e., to the duration of corresponding period with food. 



'Computed to basis of 6 hours. 



4 Subject finished eating about 1$ hours after the beginning of this period. 



H. R. D., April 10-11, 1906. The food taken in this experiment 

 was 37 grams dry cereal, 111 grams sweet chocolate, 95 grams peanut 

 butter, 233 grams baked beans, 76 grams apples, 307 grams milk, 

 409 grams cream, 67 grams whole- wheat bread, and 229 grams boiled
