1 The experiments of Jan. 17, 18, and 19 were made following 1, 2, and 3 days, respectively, with carbohydrate- 
poor diet (100 grams carbohydrates per day). 
2 The experiments of Jan. 24, 25, and 26 were made following 1, 2, and 3 days, respectively, with carbohydrate- 
rich diet (ca. 400 grams carbohydrates per day). 
3 The experiments of Feb. 7, 8, and 9 were made following 1, 2, and 3 days, respectively, with carbohydrate- 
poor diet (100 grams per day). 
* The experiments of Feb. 14, 15, and 16 were made following 1, 2, and 3 days, respectively, with carbohydrate- 
rich diet (ca. 400 grams carbohydrates per day). 
6 The lying periods for Mar. 6, Mar. 29, and Apr. 16 were made with a somewhat modified apparatus. 
6 These respiration records are for the full period, from kymograph records. Records of the ventilation were 
also taken. 
7 The tightness of the system was tested. At the end of the third period the subject said he had a headache. 
figures shows, however, that these extreme variations are but rarely met with. 
Thus, values higher than 4 c.c. are recorded but twice and values less than 
3.49 c.c. are recorded but three times. To the writers it appears obvious, 
however, that it is practically impossible to obtain an average base-line in
