218 A BIOMETRIC STUDY OF BASAL METABOLISM IN MAN. 



In percentages of the theoretical heat-production they range from 4.5 

 to 20.1 lower than in men of the same weight, stature, and age. Thus 

 this series of measurements by another group of observers, whether 

 analyzed by the simple method of averages, as on page 204, or by the 

 special methods here employed, fully confirms the conclusions drawn 

 from our own data. 



We must however in this connection refer to certain considerations 

 to be taken up in the following chapter (p. 232). 



A discussion of the data on the metabolism of German men and 

 women recorded by Magnus-Levy and Falk is reserved for the following 

 chapter (page 232). 



TABLE 84. Deviations of metabolism of individual women from the masculine standard. 

 (Note the high proportion of cases in which metabolism is lower.) 



In the foregoing discussion comparisons have been made on the 

 basis of differences in the empirical and theoretical average metabolism 

 of individuals of various ages, statures, body-weights, body-surfaces, 

 of various statures and body-w T eights, and of various statures, weights, 

 and ages. As far as we know, these methods of comparison are free 

 from all objections and give conclusive results. They fail, however, 

 to give the distribution of the individual errors of predicting female 

 from male metabolism due to the sexual differentiation which has 

 been shown to exist. 



These errors we have seriated in a grouping of 75 calories range in 

 table 84. The entries in the first four frequency columns of this table 

 show the distribution of the deviations of the actual heat-productions 

 of our women from the values which would most probably be found if 

 they were men of like age, stature, body-weight, or body-surface area
