METABOLISM AS AFFECTED BY GROWTH.

points on the charts in one scatter-diagram and sketching a curve 

 indicating the general trend would obviously smooth the individual 

 differences, not only for the same child from day to day, but between 

 the children studied. This we have not done, but recognizing the 

 value of grouping all observations in a series of charts so as to present 

 the general trend of metabolism of a relatively large number of chil-

dren, and thus visualize the influence of sex, age, weight, and surface 

 on metabolism, we have gathered together not only the data from the 

 23 individual charts in figures 15 to 21, but also the isolated observa- 

 tions on a large number of children, mostly of the higher ages, and 

 plotted these values in several scatter- diagrams. In these diagrams 

 the caloric output is referred respectively to age, weight, and surface 

 area in a number of ways.
