GASEOUS METABOLISM DURING REST.

formula of Meeh. The heat production per square meter of body- 

 surface per 24 hours for each of the subjects has been computed for 

 the days used in the previous comparison, i. e., October 1, November 

 24, and January 26, and recorded in table 130. With the heat pro- 

 duction per kilogram of body-weight there were a number of instances 

 in which there was no decrease as the experiment progressed and occa- 

 sionally even slight increases. When the values for heat production 

 at these periods are compared on the basis of per square meter of body- 

 surface, we find no increase except with Kon, whose heat production 

 increased from 836 to 846 calories. In one case, Vea, the decrease on 

 January 26 was small. The most marked decreases were noted between 

 October 1 and November 24, as would be expected, for the latter date 

 represents a period when the body-weight was practically at a mini- 

 mum. Between November 24 and January 26 there was relatively 

 little change in weight.

 ments) at different diet levels — Squad A; subjects post-absorptive and in lying position.

2 Minimum during sleep, after standard supper (700 calories) at restaurant from 6 to 12 hours 



before the experiment. Computed from values in table 131, for experiments on Sept. 



29-30, Nov. 24-25, and Jan. 26-27. 



When a comparison is made with the data in table 113 (see p. 493), 

 it is seen that the values in table 130 are not abnormal, although they 

 show a somewhat wide range from a minimum of 871 with Bro to a 

 maximum of 1,027 with Mon, a range of 156 calories. On November 

 24 we find all the values were perceptibly lowered, with no values 

 above 914 calories, this maximum value being for Mon. The minimum 

 value for this date, 759 calories, instead of being with Bro as on October
