 Urinated and defecated between fifth and sixth food periods, resting about 

 15 minutes afterward. Nitrogen in urine per hour 6 h 45 m a. m. to 10 h 30 m 

 a. m., 0.33 gram; 10 h 30' n a. m. to Il h 50 m a, m., 0.25 gram. 



L. E. E., 8 h 44 m a. m. to 3 h 19 m p. m., May 15, 1911. 60.3 kilograms. 

 Quiet throughout experiment with occasional slight movements; asleep in last 

 two or three minutes of fourth food period. Defecated at 12 h 55 m p. m. 

 Nitrogen in urine per hour 8 a. m. to 10 h 05 m a. m., 0.61 gram; 10 h 05 m a. m. to 

 12 h 55 m p. m., 0.48 gram; 12 h 55 m p. m. to 3 h 30 m p. m., 0.30 gram. 



A. F. G., 8 h 38 m a. m. to 2 h 05 m p. m., May 20, 1911. 53.9 kilograms. Lay 

 down on couch at 8 a. m. after drinking a glass of water. Quiet in first and 

 second basal periods ; in first food period somewhat nervous and apprehensive. 

 In third food period, there seemed to be a leakage of air, but it was not located. 

 Nitrogen in urine per hour 6 h 30 m a. m. to 10 h 56 m a. m., 0.36 gram; 10 h 56 m 

 a. m. to 2 h 30 m p. m., 0.48 gram. 



C. H. H., 8*42 m a. m. to 2*25 m p. m., May 10, 1911. 55.5 kilograms. 

 Awake and quiet throughout experiment; much more wide awake in last 

 period than in preceding. Found it difficult to take full amount of sucrose. 

 Nitrogen in urine per hour 7 a. m. to 12 h 12 m p. m., 0.34 gram; 12 h 12 m p. m. to 

 2 h 40 m p. m. 0.68 gram. 



H. L. H., 8 h 31 m a. m. to 2*2 l m p. m., May 17, 1911. 59.9 kilograms. 

 Quiet and awake throughout experiment; in first basal period had difficulty 

 in breathing due to a cold; larger nosepieces were given him before second 

 basal period, which enabled him to breathe more easily, although nosepieces 

 gave him more or less discomfort owing to soreness of nostrils due to cold. 

 In second food period pulse rate high, probably due to fact that visitors were 

 expected. Nitrogen in urine per hour 10 h 52 ra a. m. to 2 h 52 m p. m., 0.43 gram. 



Professor C., 8 h 46 m a. m. to ll*35 m a. m., November 20, 1909. 83.0 kilo- 

 grams. First food period only 10 minutes long. Defecated at 10 h 15 m a. m. 

 Nitrogen in urine per hour 10 h 15 ra a. m. to Il h 35 m a. m., 0.79 gram. 



Professor C., 8 h 37 m a m. to 2*42 p. m., November 22, 1909. 83.0 kilo- 

 grams. First food period 10 minutes long; intermission between basal and 

 food periods, 3 hours and 51 minutes. During intermission went on roof of 

 laboratory; sat there from 9 h 45 m a. m. to Il h 15 m a. m., without coat and part of 

 time without vest; temperature of air 6.9 C.; a little rain; sugar and coffee 

 taken after exposure to cold. Time between return from roof and beginning 

 of first food period 2 hours and 10 minutes; lay on couch much of this time 

 and a series of three observations were made not included in this record. 

 Between first and second food periods and in third food period, nervous and 

 restless. Nitrogen in urine per hour 7 h 40 m a. m. to Il h 15 m a. m., 0.65 gram. 



A. J. 0., 9 h 07 m a. m. to ll*57 m a. m., December 29, 1914. 70.0 kilograms. 

 Length of periods irregular, ranging from 3 to 10 minutes. Nitrogen in urine 

 per hour, 8 a. m. to 12 h 20 m p. m., 0.69 gram. 



J. J. C., I h o3 m p. m. to 5*2S m p. m., November 22, 1910. 64.3 kilograms. 

 high-carbohydrate diet on preceding day. Quiet throughout basal periods, 

 very quiet in second basal period ; slept between second and third periods and 

 in third basal period was kept awake with difficulty. In third basal period, 

 lower lip dropped sufficiently to show the teeth; adhesive plaster was used 

 over mouth in succeeding periods. So sleepy in last basal and in all food 

 periods that constant attention of observer was required to keep him awake;
