THE TABLES: EXPLANATORY 11 



tion between the indices in the Tables and the actual 

 observations. 



PURPOSE OF THE TABLES. The Tables are intended 

 to be used for the following purposes: 



1. The determination of what are the normal pro- 

 portions between the weight, the trunk-length, and 

 the circumference of the chest. 



2. To gain evidence as to underfeeding or malnutri- 

 tion during different stages of adolescent or adult 

 life, as well as in various classes and occupations 

 of the population. 



3. For the study of the different aspects of physical 

 fitness as measured by vital capacity in its relation 

 to weight, trunk-length, and chest-circumference; 

 for the comparison of adolescents with adults, and of 

 the male sex with the female ; for the comparison of 

 different trades, occupations, and classes one with 

 another, referring all to a definite common standard. 



4. The application of these various measurements to 

 patients with organic disease e.g. pulmonary tu- 

 berculosis, as well as to persons with functional 

 disorders e.g. industrial fatigue, the fatigue of 

 aviators, and so on. 



To gain information on these various points, it is 

 obvious that the Tables must be used in the correct 

 manner. To ensure this, a detailed description of their 

 use, application, and limitations is now given. 



To FIND OUT IF THE WEIGHT is NORMAL. To ascer- 

 tain if the weight of an individual or group of individuals 

 is normal, proceed as follows: Having ascertained the 

 trunk-length and the chest-circumference, find first in 

 Table I or Table VII the weight corresponding to the 

 observed trunk-length, then look up the weight for the 

 observed chest-circumference in Table II or Table
