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 10h52m a. m. to 2h52m p. m., 0.43 gram.

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 Up 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; in spite of all efforts, went to sleep in last period.

Low-carbohydrate diet on preceding day. Very quiet in basal periods, most of time asleep; asleep at end of both first and second food periods; during third period adhesive plaster became loosened while subject was asleep; he doubtless inhaled air; in seventh period, slept most of time but was constantly awakened by observer. To prevent possible leakage of air during sleep, rubber bandage used around head and over upper lip in eighth and ninth food periods, but even with this device mouth apparently opened once in latter period; as bandage caused discomfort, it was removed and only the adhesive plaster alone used thereafter. Awake in last period. Nitrogen in urine per hour 8h25m a. m. to 4h40m p. m., 0.48 gram.

High-carbohydrate diet on preceding day. Wooden head-rest used. Subject slept between first and second basal periods and continued to be very sleepy, requiring entire attention of one observer to keep him awake. In first food period not so sleepy as previously, but observer spoke to him frequently to make sure that he was awake; slight activity in second food period; several movements in fourth food period; asleep most of fifth and sixth periods, although frequently awakened. In seventh and eighth periods fell asleep; when awakened made slight movements; in last period drew deep breath. Nitrogen in urine per hour 7h30m a. m. to 3h44m p. m., 0.39 gram.

Subject sat in chair. High-carbohydrate diet on preceding day. Some sleep between second and third basal periods; coughed once in third basal period with possibility of slight loss of air; left nosepiece loosened in fourth period; possible leak in left nosepiece in fourth food period; a number of deep breaths in fifth food period; very quiet in eighth and ninth periods, but no tendency toward sleep. Nitrogen in urine per hour 7h40m a. m. to 5h23m p. m., 0.20 gram.
