HO EXAMPLES 



Therefore the person has 1-74% too little vital capacity for 

 Class A by weight. 



Vital capacity from length of trunk = 3210 c.c. 



Vital capacity from circumference of chest = 3155 c.c. 

 Averaging 3210 + 3155 -*- 2 = 3183 c.c. = (vital capacity 

 calculated from length of trunk and circumference of chest). 

 Subtracting calculated from observed vital capacity, 



3100 - 3183 = -83 c.c. 



-83 x 100-^-3183 = -2-61%. 



Therefore the person has 2-61% too little vital capacity for 

 Class A by length of trunk and circumference of chest. 



Example 4 



MALE, AGE 9 YEARS 



" Weight of body = 32-2 kilograms 



Length of trunk = 72-2 centimetres 



Observations \ ~. ,. ,. , _ ~ , . 



Circumference ot chest 67-0 centimetres 



Vital capacity = 2390 cubic centimetres 



CALCULATION 



Weight from length of trunk = 32-34 kilos. 

 Weight from circumference of chest 32-52 kilos. 

 Averaging 32-34 + 32-52 -*- 2 =32-4 kilos = weight cal- 

 culated. 



Subtracting calculated from observed weight, 

 32-2 - 32-4 = -0-2 kilos. 

 -0-2 x 100 -f- 32-4 = -0-62%. 

 Therefore the person is 0-62% too light. 



Vital capacity from weight = 2330 c.c. (Class B) = (vital 



capacity calculated from weight). 

 Subtracting calculated from observed vital capacity, 

 2390 - 2330 = +60 c.c. 

 +60 x 100 -*- 2330 H. +2-58%. 



Therefore the person has 2-58% too great vital capacity for 

 Class B by weight. 



Vital capacity from length of trunk = 2336 c.c. (Class B). 

 Vital capacity from circumference of chest = 2346 c.c. 

 (Class B).
