240 A BIOMETRIC STUDY OF BASAL METABOLISM IN MAN. 



The final difference column shows how much greater the excesses 

 are when the age term is ignored and the regression equation involv- 

 ing stature and weight only is used. 



We now turn to the problem of the metabolism rate at the other 

 extreme of the life cycle, and shall consider the metabolism of the 6 

 old men studied by Aub and Du Bois. 17 Table 96 contains the essen- 

 tial measurements and the comparison of the observed heat-production

 tion} standard when the age factor is considered and when it is ignored. 



in calories per 24 hours (indirect calorimetry) with the values predicted 

 by the use of our formula from the constants for body-weight, stature, 

 and age. 



The difference column shows that our formula has in all cases but 

 one predicted a lower metabolism for these subjects than that found 

 by actual observation. The difference between observation and 

 theory in these 5 cases is rather large, amounting to about 245 calories 

 per 24 hours. 



For comparison we may show the results of applying our equations 

 to the physical measurements of the old men and women studied by
