Urinated shortly before 7 o'clock (after enema); attempted to urinate near beginning of each period, urinating at 9h35m a. m., 12h46m, 2h32m, 3h34m, and 5h28m p. m.; unable to urinate at end of either first or second period; some pressure from urine; some sensation of fullness from water-drinking. Drank water in each period. Stooped over in third period to pick up rubber stopper from floor; reported restless in last hour of fourth period; otherwise sitting quietly in chair, reading much of time. Body-temperature: 37.34°, 37.30°, 37.26°, 37.41°, and 37.44° C. Pulse rate, 50; respiration rate, 18.

Drank water twice in first period, four times in second, once in third, and four times in fourth period. Urinated about 7h45m a. m. (after enema), three times in second, once in third, and twice in fourth period. Activity other than indicated was small; part of time reading. Body-temperature: 36.71°, 36.48°, 36.71°, 36.73°, and 36.73° C. Pulse rate, 57; respiration rate, 23.

J. J. C., 9h08ma. M. To Lh39m P. M., January 10, 1911. 63.4 Kilograms

In three basal periods went through motions of drinking water and urinating to equalize muscular activity throughout experiment; an effort was also made to minimize activity by having urine jars and drinking-water on table conveniently placed and by use of bent-glass tube in drinking. Urinated at 7h55m and llh30m a. m., 12h03m, 12h55m, lh20m, and lh49m p. m. Drank water three times in each of the water-drinking periods. Asleep at 10h52m a. m.; also slept in first water-drinking period. On evening of experimental day had slight tendency to diarrhea, probably due to excessive water drinking. Basal periods: pulse rate, 68; respiration rate, 17. Water-drinking periods: pulse rate, 70; respiration rate, 19.

T. M. C, 8h55m A. M. To 12h40m P. M., January 12, 1911. 47.5 Kilograms

Slightly more active in water-drinking periods than in two basal periods. Urinated at 7h45m, 10h28m, llh58m a. m., 12h29m, and 12h48m p. m. In each water-drinking period subject drank water three times. Basal periods: pulse rate, 69; respiration rate, 15. Water-drinking periods: pulse rate, 70; respiration rate, 15.

J. J. C, 8h56m A. M. To 12h41m P. M., January 13, 1911. 64.9 Kilograms

At llh30m p. m. on preceding day subject ate 5 tablespoonfuls chicken salad, 1 Vienna roll, 3 cupfuls coffee, 5 macaroons, 8 or 9 lady-fingers, one large dish sherbet and ice cream, one slice walnut cake. Activity due to water-drinking and urinating in last three periods simulated in two basal periods preceding. Water taken three times in each water-drinking period. Urinated at 7h50m, 10h33m, llh44m, llh59m a. m., 12h48m, and 12h47m p. m. In first basal period sat quietly reading; in second basal period slept about 8 minutes shortly after period began and fell asleep again near end of period. As pulse rate was indistinct in first water-drinking period, he read justed stethoscope. Basal periods: pulse rate, 61; respiration rate, 18. Water-drinking periods: pulse rate, 58; respiration rate, 19.
