total heat. The actual differences and their probable errors appear in 

 table 32. The correlations are consistent throughout in indicating a 

 more intimate relation between body-weight and total heat-production 

 than between stature and total heat-production. Notwithstanding the 

 (statistically) few individuals considered, a number of the differences 

 may be looked upon as individually significant in comparison with 

 their probable errors.

The differences in correlation vary considerably from series to 

 series, ranging from 0.017 ==0. 108 in the 19 men of the second sup- 

 plementary series to 0.566 ==0.086 in the original women. We note, 

 however, that the probable error is so high in the case of the second 

 supplementary series of men that it can not really be asserted to differ 

 significantly from the other groups of men. The larger groups of men 

 show a difference of the order r wh r sh =0.19. In the women the differ- 

 ences are much larger because of the very low correlations between 

 stature and total heat-production. 



In the preceding section we considered the influence of age on the 

 correlation between body-weight and total heat-production. It now
