CALCULATION 



Weight from length of trunk = 64-98 kilos. 

 Weight from circumference of chest = 6445 kilos. 

 Averaging 64-98 + 64-45 -r- 2 = 64 7 kilos = weight calcu- 

 lated. 



Subtracting calculated from observed weight, 

 59-8 - 64-7 = -4-9 kilos. 

 -4-9 X 100 -f- 64-7 = -7-57%. 

 Therefore the person is 7-57% too light. 



The vital capacity calculated from weight will obviously be 

 too small on account of the person being under weight. 



Vital capacity from length of trunk = 4230 c.c. (Class A). 

 Vital capacity from circumference of chest = 4205 c.c. 

 (Class A). 



Averaging 4230 + 4205 -5- 2 = 4218 c.c. (Class A) = (vital 

 capacity calculated from length of trunk and circumference of 

 chest). 



Subtracting calculated from observed vital capacity, 

 4700 - 4218 = +482 c.c. 

 +482 X 100 -*- 4218 = +11-43% 



Therefore the person has 11-43% too great vital capacity for 

 Class A by length of trunk and circumference of chest. 



Example 9 



MALE, AGE 25 YEARS 



Weight of body = 69 - kilograms 



Length of trunk =887 centimetres 



Observations ~. , , , or _ 



Circumference of chest = 85'0 centimetres 



Vital capacity = 4200 cubic centimetres 



Weight from length of trunk = 61-65 kilos. 

 Weight from circumference of chest = 62-42 kilos. 

 Averaging 61-65 + 62-42 *- 2 = 62-0 kilos = weight calcu- 

 lated.
