172 METABOLISM AND GROWTH FROM BIRTH TO PUBERTY. 



found in our own results, has also been laid on the chart, although 

 here again it must be emphasized that this curve was drawn with 

 great difficulty and simply shows the general trend in a diagram, 

 with very wide dispersion of the various points. 



While comparison with figure 42 shows that few of these points lie 

 outside of the field of our observations, yet we should note that, with 

 the exception of one boy weighing about 6 kg., the points for the 

 children earlier studied lie above our sketched curve. Furthermore, 

 if a smoothed curve were laid through the earlier observations, it 

 would have approximately the same general trend as our own curve, 

 although at a higher level. % 



While our own data do not warrant the extension of our smoothed 

 curve beyond 42 kg., the data for certain heavier boys should here be 

 recorded. In the 1918 series of Du Bois, the values for four boys, all 

 weighing about 49 kg., are reported and are given in table 30. With 

 all four boys the surfaces were actually measured. 



TABLE 30. Values outside 

 weight range in figure 44 (Du 

 Bois). 



TABLE 31. Values outside heat range in figure 44 

 (Magnus-Levy and Falk) . 



Magnus-Levy and Falk report the heat production of three boys, 

 each with such a high value that it would be necessary to extend 

 our chart beyond permissible limits to include them, although they 

 weighed less than 21 kg. Table 31 shows the data for these three boys. 



It is clear that the points for 6 of the 7 boys would lie very con- 

 siderably above our line if projection beyond the 42-kg. level were 

 permissible. Since we believe that the projection would in all prob- 

 ability fall somewhat lower rather than continue on a level, all of 

 the 7 boys would be above the projected line, although the value for 

 the boy weighing 48.6 kg. studied by Du Bois would fall practically 

 on the line. 



With girls the number of earlier observations is extremely few, 

 hardly justifying special chart treatment. The values have been 

 plotted, but are not reproduced here. All of the values are con- 

 siderably above our smoothed curve. The earlier data for girls 

 are altogether too sparse to warrant even an attempt to lay on a 

 smoothed curve, so no comparisons with our general trend are 

 possible.
