THE TABLES: EXPLANATORY 



THE annexed Tables give information regarding the 

 weight of the human body in its relationship to the length 

 of the trunk (i.e. the height sitting), the circumference

No data regarding the height standing are given, for 

 the reasons indicated in the Introduction. It will also 

 be seen that no reference is made to the age of the indi- 

 vidual, because, for the range of indices given, it has 

 been found that the question of age is of little or no 

 importance up to an age of about 50 years. 



To make proper use of the Tables, and to secure com- 

 parable results, it is essential that all measurements 

 should be taken uniformly and as nearly as possible in 

 the following manner: 



MEASUREMENTS 



WEIGHT. All the weights quoted are net weights of 

 the body without clothes. When it is found desirable to 

 weigh an individual wearing a garment, the weight of 

 the garment must be ascertained and deducted from the 

 observed total weight, so that the record of the actual 

 net weight without clothes is obtained. 



LENGTH OF THE TRUNK. The trunk length is taken 

 by means of the special measuring apparatus shown in 

 Fig. 1. It is taken with the subject sitting on the platform, 

 the following points being carefully observed: 



The subject places the backs of the fingers upon the 

 platform on which he sits, and, with the fingers pointing
