THE TABLES: EXPLANATORY 11 



in the non-metric system is that use of the decimal system 

 enables one to determine most easily the percentage 

 deviation 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 com- 

 parison 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 

 tuberculosis, 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.
