remains when it is reduced to calories per square meter of 

 body surface does not, however, warrant the conclusion that 

 metabolism is independent of bodily dimensions. 



To investigate this problem we have merely to group all 

 individuals according to some physical character and to deter 

 mine whether metabolism changes with variation in the mag 

 nitude of the selected physical dimension. For example, Fig.

of each individual on the horizontal and the vertical scales by 

 a dot. It will be seen at a glance that the metabolism of men 

 of any stature is highly variable. Nevertheless there is an 

 orderly trend in the swarm; there is a marked tendency for 

 taller men to show greater daily heat production. 



Such relationships may be represented in a different way. 

 Take another physical character for purposes of illustration. 

 One may determine the average daily heat production of indi-
