INGESTION OF CARBOHYDRATES. 205 



cooperation of Professor Otto Cohnheim, formerly of Heidelberg, who 

 kindly volunteered as a subject while he was a guest of the Nutrition 

 Laboratory in the fall of 1909. The details of the experiments with 

 Professor Cohnheim are given in tables 154 and 155. The details of 

 the whole series of respiration experiments following the ingestion of 

 carbohydrates are given in tables 126 to 168. Statistical data not 

 included in the tables are given in the following pages for a number 

 of the experiments. When no further data are available, no mention 

 is made of the experiment in the statistical text.

 Very quiet in first basal period, probably slept a little; marked tendency to 

 fall asleep in second period; in second, third, and sixth food periods, necessary 

 for observer to speak to the subject often to prevent his falling asleep; in last

 quiet in first basal period; asleep a few moments before end of third period; 

 somewhat restless in fourth basal period. Asleep a few moments in first 

 and third food periods, also slept during intermissions between second and 

 third food periods and between third and fourth food periods. Nitrogen in 

 urine per hour 7 h 40 m a. m. to Il h 08 ra a. m., 0.46 gram; Il h 08 m a. m. to 12 h 57 m 

 p. m., 0.53 gram; 12 h 57 m p. m. to 4 h 06 m p. m., 0.31 gram.

H. L. H., 8 h 40 m a. m. to 3 h 54 m p. m., May 24, 1911. 59.8 kilograms. 

 Very quiet and awake in basal periods; after taking dextrose, also very quiet 

 and awake; very warm in seventh food period and asked to have electric fan 

 set in motion. Nitrogen in urine per hour 7 h 35 m a. m. to Il h 30 m a. m., 0.53 

 gram; Il h 30 m a. m. to 3 h 20 m p. m., 0.44 gram. 



P. F. J., 8 h 46 m a. m. to 2 p. m., May 15, 1912. 56.8 kilograms. Consid- 

 erable movement between first and second food periods, also between third and 

 fourth food periods. Nitrogen in urine per hour 7 h 30 m a. m. to 2 h 05 m p. m., 

 0.49 gram. 



J. J. C., Il h 04 m a. m. to 2 h 24 m p. m., December 22, 1910. 64.7 kilograms. 

 High-carbohydrate diet on previous day. Sat down at 10 h 47 m a. m. in com- 

 fortable Morris chair, with foot-rest. Adhesive plaster used to secure perfect 

 closure of mouth. In first basal period wide awake, but more sleepy as experi- 

 ment continued; very sleepy in fourth basal period. After dextrose, awake 

 all of first period but inclined to be drowsy near end; drowsiness increased in 

 second food period; very sleepy in third food period; went to sleep in fourth 

 food period, while observer was talking to him; occasional slight movements 

 in sleep. Was cold at beginning of first food period and used blanket most of 

 experiment. Nitrogen in urine per hour 8 h 15 m a. m. to 2 h 33 m p. m., 0.44 gram. 



J. J. C., 9 h 05 m a. m. to 5 h 29 m p. m., December 28, 1910. 64.7 kilograms.- 

 High-carbohydrate diet preceding day. Wooden head-rest used in experiment. 

 Slept most of time in second and third basal periods, probably awake in last 

 basal period. Slept most of third, fourth, and fifth food periods; no attempt 

 made to keep him awake in fourth and fifth periods; probably awake in first 

 and sixth food periods; very wide awake in seventh food period. Some pain
