METABOLISM EXPERIMENT No. 107. 



Subject, B. F. D., June 2, 1905. (Same subject as in 

 experiment No. 103.) 



This experiment was a continuation of the series made with this subject 

 to ascertain whether he would experience further toxic symptoms on remaining 

 in the calorimeter for gradually increasing periods of time. At about 1 o'clock 

 the subject ate dinner, consisting of fish, mashed potatoes, lettuce with vinegar 

 and sugar, bread and butter, and pudding with sugar sauce. After dinner he 

 entered the calorimeter, was weighed at l h 52 m p. m. and then sat quietly until 

 the beginning of the experiment at 2 h 44 m p. m. At the beginning of the first 

 period he went to the food aperture once and then sat down and read. At 

 the beginning of the second period (4 h 45 m p. m.) he rose from his chair, went 

 to the food aperture, and opened it twice. At 5 h 40 m p. m. the subject rose 

 from his chair, went to the food aperture, took out the material for his supper, 

 and then sat down and began eating. Soon afterwards he stood up again and 

 opened the food aperture. At 6 h 10 m p. m. he finished eating supper, and then 

 passed 160 grams of urine. At the beginning of the third period (6 h 45 m p. m.) , 

 he opened the food aperture twice. The experiment was finished at 8 h 45 m p. m. 

 The subject reported that he was rather sleepy at first, but became more awake 

 at 3 o'clock. No unfavorable symptoms were noticed. 



The subject's supper consisted of 483 grams of strawberries, 235 grams of 

 sandwich, 81 grams of sugar, and 466 grams of milk. The subject recorded 

 his own pulse-rate, the results being as follows : 2 h 45 m p. m., 65 ; 5 h 20 m p. m., 

 46 ; 5 h 52 m p. m., 45 ; 7 h 05 m p. m., 61 ; 8 h 32 m p. m., 65. The sublingual tem- 

 peratures were: at 2 h 45 m p. m., 97.9 P. ; 4 h 45 m p. m., 98.0 F. ; 6 h 45 m p. m., 

 98.0 F.; 8 h 45 m p. in., 98.0 F. The results obtained from the measurements 

 of the three 2-hour periods are given in table 44. 



METABOLISM EXPERIMENT No. 108. 



Subject, B. F. D., June 3, 1905. (Same subject as in 

 experiment No. 103.) 



This experiment was a continuation of the series with B. F. D. to determine 

 the nature of a toxicity which subsequently appeared to be due to mercurial 

 poisoning from the air in the respiration chamber entering from the ventilating 

 system. 



Breakfast consisted of 3 biscuits, fried potatoes, and about 350 c. c. of milk. 

 The subject entered the chamber and was weighed at 10 h 50 m a. m. and the 

 first period began at 12 b 45 m p. m. Immediately afterwards the subject rose 

 from his chair, went to the food aperture and sat down again. At l h 50 m p. m. 

 he went to the food aperture twice and then commenced eating. While eating, 

 he rose 3 times and stood for a few minutes, then sat down, and shortly after- 

 wards again rose and took milk from the food aperture. His lunch consisted 

 of 114 grams of sandwich, 75 grams of canned baked beans, 214 grams of
