BASAL METABOLISM.

and the values in the "first period" commonly represent the values 

 obtained approximately in the period between 9 a. m. and 11 a.m. 

 Averages are given for each period and also for each experimental day. 

 The carbon-dioxide production and oxygen consumption are shown in 

 two significant figures and the heat production in three significant 

 figures. The weighings of the carbon-dioxide are accurate to the tenth 

 of a gram, but as there is always an uncertainty in determining the 

 residual amount of carbon dioxide in a chamber of so large a volume as
