numerically higher constants than those obtained by the use of the 

 Meeh formula. 



These results have an obvious bearing upon the so-called Rubner's 

 or body-surface law, to be discussed in detail in Chapter VI. 



5. WEIGHT AND GASEOUS EXCHANGE. 



The correlation coefficients for body-weight and oxygen consump- 

 tion and for body-weight and carbon-dioxide excretion appear in table 

 24. For both gases the correlations are for the most part of a rather 

 high order of magnitude and, with certain exceptions to be discussed 

 in a moment, of a high degree of consistency. 



TABLE 24. Correlations between body-weight and gaseous exchange. 





Generally speaking, the correlations for both weight and oxygen 

 consumption and weight and carbon-dioxide production are of the order 

 r=0.75 in men that is to say of three-quarters of perfect inter- 

 dependence. This is also true in the original series of women. The 

 second series, of only 35 women, shows a much lower degree of inter- 

 dependence, with the result that the total women show a correlation 

 of the order r = 0.60. 



Among the men the small second supplementary series shows the 

 lowest relationship, measured by a coefficient of about the same order 

 as those found in the women. 



We shall consider the relative values of the correlations between 

 physical characters and oxygen consumption and carbon-dioxide pro- 

 duction, and the relative magnitudes of the correlations for weight 

 and gaseous exchange and stature and gaseous exchange after the
