EXPLANATION OF TABLES. 



TABLE No. 2. 



Material. — Tlie men of wlioso iinrticulars this table is composed were colored 

 men born in the United States. Their nnmber is 25,828, and it inclndes not only pure 

 neg-roes, bnt nndattoes of every degree of hybridity. These men belonged to the 

 classes of recrnits, snbstitutes, drafted men, and enrolled men ; and their number 

 includes those rejected as avcU as those found fit for military service. The larger por- 

 tion of them were recruits, (volimtecrs.) 



The purpose of this table, and its construction, are identical Avith those of Table 

 No. 1, so that the explanations given Avith the latter apply with equal precision to this. 

 The ratios, which relate to the whole number of men examined, refer, of course, in this 

 table to 25,828 men instead of to 315,620, as in Table No. 1. 



TABLE No. 3. 



Material. — 501,068 men, of 24 different races or nativities, are represented in this 

 table. These men belonged to the classes of recruits, substitutes, drafted men, and 

 enrolled men ; and their number includes those rejected as well as those found fit for 

 military service. 



PuKPOSE. — The purpose of Table No. 3 is, like that of the two preceding tables, to 

 illustrate the relation borne to stature by girth of chest, and expansion of chest. There 

 is necessarily no relation to locality to be developed, race or nativity taking its place. 



Construction. — This is precisely like that of Tables No. 1 and No. 2, and exhibits 

 a series of eight tables which represent the eight degrees of stature. 



Totals. — As there are no subdivisions corresponding to the congressional districts of 

 the States of the Union, there are, in consequence, no horizontal lines of totals, excepting 

 one such at the end of each series, viz, at pages 168, 172, 176, 180, 184, 188, 192, and 

 196. This line of "totals," which corresponds to the lines marked " Grand totals for 

 United States" in the two preceding tables, displays the total number of mentor all 

 nativities, 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 vertical totals show the total number of men of each nativity, at each of the six 

 degrees of girth of chest — and (on the extreme right) at the height which heads the 

 page. 



The colunms of " Grand aggregate," which conmience at page 195, show the total 

 number of men {oj all dimensions) of each nativity. 



Ratios. — The ratios set underneath totals which refer to all nativities necessarily 

 relate to the whole number of 501,068 men. The ratios appertaining to totals oi the 

 details of any one nativity relate to the whole number of men examined of that nativity. 



The explanation of the ratios in Table No. 1 applies equally to the ratios of this 

 table. 



Example. — If the column headed "United States, White" lie selected as the illus- 

 tration, it will be seen, on page 167, that there were 1,674 men of that nativity who 

 were " under 61 inches in height." The ratio of that total to 315,620, being tliewhole
