METABOLISM IN SEVERE DIABETES. 



Respiration Experiment No. U2. 



Date, May 19, 1910. Body-weight without clothing, 39.3 kilos. 



A breakfast consisting of a dish of oatmeal, an egg, a piece of bacon, and a 

 cup of coffee was taken before the experiment. The day preceding was an 

 "oatmeal day," and as the subject usually felt considerably better on these 

 days, it seemed desirable to determine the respiratory quotient under such 

 circumstances. 



The subject arrived at the laboratory about 10 h 15 m a.m., lay down on the 

 couch at 10 h 30 m a. m., and the experiment began at 10 h 40 m a. m., continu- 

 ing for three periods of 10 to 11 minutes, with intermissions of 9 to 12 minutes. 

 The subject urinated before the experiment at 8 h 30 m a. m., and afterwards at 

 1 1 h 50 m a. m. The records of the experiment may be found in table 78.

2 Carbon dioxide eliminated per kilogram per minute.4.02 c.c; oxygen absorbed per kilogram per 



minute, 5.52 c.c. The urine collected between 8 30 m and ll' 1 50 m a.m. amounted to 323 c.c. 



and contained 1.20 gms. nitrogen and 15 gms. sugar. 



Respiration Experiment No. U3. 



Date, May 26, 1910. Body-weight without clothing, 41 .2 kilos. 



The subject came to the laboratory without breakfast about 8 h 30 m a. m., 

 and lay down upon the couch for 10 minutes before the experiment began at 

 8 h 44 m a. m. Three periods of about 10 minutes each were included in the 

 experiment, with intermissions of 10 to 12 minutes. The subject urinated at 

 7 a. m. before coming to the laboratory, and again at 9 h 45 m a. m. After the 

 experiment was over she was given a breakfast consisting of oatmeal with 

 cream, and boiled eggs. The records of the experiment are given in table 79.

'Carbon dioxide eliminated per kilogram per minute, 3.76 c.c; oxygen absorbed per kilogram per 

 minute, 4.95 c.c. The urine collected between 7 and 9 h 45 m a. m. amounted to 274 c.c. and 

 contained 0.64 gm. nitrogen and 2.8 gms. sugar. 



Respiration Experiment No. U4. 



Date, September 13, 1910. Body-weight without clothing, 44.2 kilos. 



This experiment followed a breakfast taken at 6 h 45 m a. m. consisting of 

 oatmeal and cream, small amounts of melon and bacon, and an egg. She 

 reached the laboratory at 10 h 45 m a. m., and almost immediately lay down
