XII EXPLANATION OF TABLES. 



Construction. — Light complexion is associated Avith light liair, and eyes of blue or 

 gray color ; dark complexion, with dark hair, and black or hazel eyes. 

 Age is divided into 6 periods, as follows : 



Under 20 years. 

 20 years, and under 25 years. 

 25 years, and under 30 years. 

 30 years, and under 35 years. 

 35 years, and under 40 years. 

 40 years, and over. 



Stature, as in the preceding tables, is divided into eight degrees, which commence, 

 respectively, at pages 200, 202, 204, 206, 208, 210, 212, and 214. Each degree thus 

 occupies a double page. Under each of these degrees of stature will be found : 



1. The circumference of chest at expiration in six consecutive columns, denoting the 

 six degrees of girth described. 



2. Beneath each degree of girth of chest, four columns denoting the four degrees of 

 expansion of chest. 



In this manner is shown, under each variety of complexion, and at each period of 

 age, the number of men (of the height specified at the top of the page) at each degree 

 of circumference of chest at expiration ; and at each degree of circumference of chest 

 ft shown the number of men presenting each degree of expansion of chest. 



By adding the rate of expansion of chest to the giith of chest at expiration, the cir- 

 cumference at inspiration is obtained. 



Totals. — 1. Complexion. — The horizontal line of totals shows the number of men 

 of both varieties of complexion at each of the four degrees of expansion of chest — at each 

 of the six degrees of girth of chest — and (on the exti-eme right) at the height which 

 heads the page. The vertical lines of totals show the number of men of each variety 

 of complexion at each of tlie six degrees of girth of chest — and (on the extreme right) 

 at the height specified at the top of the page. The column of "Grand aggregate," on 

 page 215, shows the total number of men, irrespective of dimensions, of each variety 

 of complexion ; and the addition of these gives the whole number of the table, namely, 

 190,621 men. 



2. Age. — The horizontal line of totals shows the number of men of all ages at each 

 of the four degrees of expansion of chest — at each of the six degrees of girth of chest — 

 and (on the extreme right) at the height specified at the top of the page. The verti- 

 cal totals show the number of men of each period of age at each of the six degrees of 

 girth of chest — and (on the extreme right) at the height which heads the page. The 

 column of "Grand aggregate," on page 215, shows the total number of men, irrespec- 

 tive of dimensions, of each period of age ; and the addition of these gives the whole 

 number of the table, namely, 190,621 men. 



Ratios. — The ratios in every instance refer to the whole numljer of men of the 

 entire table, namely, 190,621 men. 



ExAiiPLE. — ^On page 201, it will be seen that there were 438 men of light complex- 

 ion who were " under 61 inches in height." The ratio of that number to the 190,621
