per from floor; reported restless in last hour of fourth period; otherwise sit- 

 ting 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. 



A, W. W., 8 h %4 m a. ro. to 4 h 24 m p. m., March 27, 1907. 58 kilograms. 

 Drank water twice in first period, four times in second, once in third, and 

 four times in fourth period. Urinated about 7 h 15 m 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. 



/. /. C., 9 h 08 m a. m. to l*39 m 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 conven- 

 iently placed and by use of bent-glass tube in drinking. Urinated at 7 h 55 m 

 and Il h 30 m a. m., 12 h 03 m , 12 h 55 m , I h 20 ra , and I h 49 m p. m. Drank water three 

 times in each of the water-drinking periods. Asleep at 10 h 52 m 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., 8 h 55 m a. m. to 12 h 40 m p. m., January 12, 1911. 47.5 kilograms. 

 Slightly more active in water-drinking periods than in two basal periods. 

 Urinated at 7 h 15 m , 10 h 28 m , Il h 58 m a. m., 12 h 29 m , and 12 h 48 ra 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; respira- 

 tion rate, 15. 



J. J. C., 8 h o6 m a. m. to 12 h 41 m p. m., January 13, 1911. 64.9 kilograms. 

 At Il h 30 m 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. Uri- 

 nated at 7 h 50 m , 10 h 33 m , Il h 14 m , Il h 59 m a. m., 12 h 18 m , and 12 h 47 m 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 readjusted stetho- 

 scope. Basal periods : pulse rate, 61 ; respiration rate, 18. Water-drinking 

 periods: pulse rate, 58; respiration rate, 19.
