METABOLISM IN ANIMALS OF DIFFERENT SIZE 



119 



The results of Camerer and others on the amount of food taken by chil- 

 dren of different ages give exactly the same result. We give here only the 

 figures obtained by Camerer. 



In infancy., as was to be expected, the metabolism per kilogram of weight 

 proves to be much higher than in adult life; but calculated per unit of 

 surface of the body it is decidedly less than in children somewhat older 

 (cf. the following table). This is probably connected with the fact that 

 the new-born child sleeps most of the time and the tonus of its muscles is but 

 slightly developed.
