CHAPTER III. 



INDIVIDUALS AND MEASUREMENTS CONSIDERED. 



In the first of the three sections into which this chapter is divided 

 we list up and briefly discuss the measurements (both physical and 

 physiological) considered in these pages. 



In the second section we catalogue the series of individuals with the 

 results of the measurements which have been made upon them. These 

 are the data upon which our constants are based. 



In the third section we apply certain criteria adapted to determining 

 the suitability for the purposes of the present study of the individuals 

 upon whom measurements have been made. 



1. MEASUREMENTS CONSIDERED. 



The following are the measurements which have been considered. 

 The symbol in parenthesis is the one used to designate the measurement 

 in the statistical formulas. A brief explanation of the method employed 

 in making the determination is given later. 



Stature (s), or height, in centimeters. 



Body-weight (w), in kilograms. 



Body-surface, or area, in square meters, as estimated by Lissauer formula (a/.). 



Body-surface, in square meters, as estimated by Meeh formula (a M }. 



Body-surface, in square meters, as estimated by Du Bois height-weight chart (a/>). 



Pulse-rate (p), in beats per minute. 



Carbon-dioxide output (c). Total in cubic centimeters per minute. 



Oxygen consumption (o). Total in cubic centimeters per minute. 



Carbon-dioxide production, in cubic centimeters per minute, per kilogram of body- 

 weight (c fc ). 



Oxygen consumption, in cubic centimeters per minute, per kilogram of body-weight 

 (0*). 



Body-temperature (i). 



Heat-production (h). Total heat-production (indirect calorimetry) per 24 hours in 

 calories. 



Heat-production per 24 hours per kilogram of body-weight (/it). 



Heat-production per 24 hours per square meter of body-surface according to Lissauer 

 formula (hi). 



Heat-production per 24 hours per square meter of body-surface estimated by Meeh 

 formula (hx). 



Heat-production per 24 hours per square meter of body-surface estimated by Du Bois 

 height-weight chart (h D ). 



The following are the details which seem essential to an understand- 

 ing of the measurements utilized. 



Stature. Stature, without shoes, was measured in adults by means 

 of a graduated vertical rod with an adjustable horizontal bar which 

 was lowered to the top of the head.
