METABOLISM AS AFFECTED BY GROWTH.

investigators on this basis. We have consequently plotted in figure 

 28 the values for boys obtained by other investigators. For purposes 

 of comparison we have laid on the smoothed curve from the chart in 

 figure 26, representing the general trend of the total metabolism of 

 boys as found by us. With the exception of one child under 6 kg. 

 of 'weight, all of the observations lie above the smoothed line. 

 Since our curve has been carried only to 42 kg., five of Du Bois's

boy scouts and one of Magnus-Levy and Falk's children are outside 

 of this range. If the curve were projected, one of these values 

 would lie approximately on the line, another somewhat below it, 

 and four considerably above it. The high values noted on the basis 

 of weight for the children studied by Magnus-Levy and Falk and by 

 Du Bois have been criticized, the Magnus-Levy and Falk values by 

 Harris and Benedict 1 and the Du Bois values in the historical section 

 of this monograph. (See page 19.) The fact that practically all 

 the values lie above the general trend found by us would imply again 

 that our curve represents more nearly the true basal value than any 

 curve that can be drawn from the earlier work, when the requirements 

 for basal conditions were apparently not so rigidly adhered to.
