230 A BIOMETRIC STUDY OF BASAL METABOLISM IN MAN. 



In constructing these tables the constant term of the equation and 

 the corrective term for body-weight are combined in table I for men 

 and table III for women. The corrective term for stature and age is 

 given in table II for men and table IV for women. These tables must be 

 used in conjunction only. Thus table I or III must not be used to esti- 

 mate the metabolism of an individual whose weight only is known. 

 Tables II or IV must not be used to estimate the metabolism of an 

 individual whose weight is unknown. 



The use of the tables presents no difficulty whatever. Three exam- 

 ples follow: 



Man 27 years Woman 22 years Woman 66 years 



old, 172 cm. in old, 160 cm. in old, 162 cm. in 



height, 77.2 htight, 77.2 height, 62.3

3. ILLUSTRATIONS OF PRACTICAL APPLICABILITY OF STANDARD 

 MULTIPLE PREDICTION TABLES OF BASAL METABOLISM. 



In a foregoing chapter (VII) the practical usefulness of the equa- 

 tions upon which these tables are based has been fully demonstrated in 

 their application to a specific problem, that of the sexual differentiation 

 in metabolic activity. It now remains to supply further illustrations 

 of their range of usefulness by applying them to certain cases in which 

 the individuals were measured by workers outside of the Nutrition 

 Laboratory, in which the individuals fall outside the range of age or 

 of physical form upon which the equations were based, or in which 

 the subjects were in a particular physiological or pathological state, 

 the influence of which upon metabolism is under investigation. 



ILLUSTRATION A. TESTS OF NORMALITY OF SERIES OF DETERMINATIONS. 



In applied calorimetry the need to be met is practically always the 

 same. One requires to know whether a special series of metabolism 

 measurements agrees with a larger series of determinations taken as a 

 standard. If the special series is made up of individuals characterized 

 by some specific condition, e.g., rationing, exercise, or disease, the 

 result of the comparison shows whether this specific peculiarity may 

 or may not be considered to have a determining influence on the basal 

 metabolism. Some special cases of this sort will be examined. 



As a first illustration of the practical usefulness of our multiple- 

 prediction equations, we may consider the agreement between certain 

 series of measurements by other observers and the standard which 

 has been based upon the Nutrition Laboratory experience. Take 

 first a series of young men and women studied by Palmer, Means, and 

 Gamble 8 and discussed in relation to the problem of the body-surface
