BASAL METABOLISM OF NORMAL MEN AND WOMEN. 209 



For the sake of a further comparison on the basis of an age grouping 

 of the women we have used the metabolism calculated from the equa- 

 tion for the regression of heat-production on body-surface as estimated 

 by the Du Bois height-weight chart in the men. The comparison is 

 made in table 78. The results, which are represented graphically in 

 the uppermost figure, D, of diagram 27, fully confirm the preceding. 

 Without exception the groups of women show average values of 

 metabolism from 13 to 273 calories or from about 1 to 18 per cent lower 

 than values computed on the assumption that their heat-production is 

 identical with that of men of like weight, stature, and age. 



TABLE 78. Differences in the metabolism of men and women, women classified according to age. 



TABLE 79. Differences in the metabolism of men and women, women classified according to stature. 



The results of a comparison of the actual heat-production in the 

 women with that computed from stature in groups of women classified 

 with respect to stature are shown in table 79. With one single excep- 

 tion, that of the 6 subjects 152 to 154 cm. in height, the women of each 

 grade of stature show a smaller actual average metabolism than that 

 computed on the assumption that they were men of like stature. The 

 lower figure, A, in diagram 28, which represents these results brings
