EXPLANATION OF TABLES. XXIII 



Example. — If phthisis pulnionahs be the disease selected for iUustration, the fol- 

 io-wing result is to be seen on page 461 : 

 Under 20 y eai's of age . 119 



All rejected on account of phthisis pul- 

 monalis. 



3,724 



Of the foregoing- list, those under 20 years of age were 119 in number, and the 

 proportion they bear to the whole number of men examined who were under 20 years 

 of age, namely, 58,952, is seen to be 2.019 in the thousand. 



The addition of the total number under each period of age, as shown at the foot 

 of page 465, gives the total number of men rejected of all ages and for all diseases, 

 namely, 122,616. It will be seen that this total number of rejected men bears to the 

 whole number examined, namely, 334,321 men, a ratio of 366.761 hi the thousand. 



TABLE No. 2 0. 



Material. — This table presents the results of the- examination of 334,321 men of 

 various nativities, and belonging to the four classes of recruits, substitutes, drafted 

 men, and enrolled men. Out of this body of men the number found fit for military 

 sei'vice was 211,705, being 633.239 in the thousand of the whole number examined. 



Purpose. — To show the occupation followed by these men at the time of their 

 enhsting or being drafted, and the proportion engaged in each occupation rejected for 

 the various forms of disease. 



Construction. — The list of diseases extends through five pages, and is repeated ten 

 times, making in all eleven tables. The occupations represented are seventy-six in num- 

 ber : seven of them form a table with the list of diseases in each of the first ten ; and six of 

 them in the last of the series. Under each heading is announced the total number of 

 men examined who were engaged in the occupation specified, and this is followed by 

 two columns, one containing the number of men rejected for each disease, and the 

 other the appropriate ratio. 



Totals. — The horizontal lines of totals are of three kinds: the "Total"' shows 

 the number of men of each occupation rejected in a subdivision of diseases; the 

 "Grand total" shows the number rejected in a class of diseases ; and the "Grand total 

 for all diseases," which is at the foot of each series, shows the number of men of each 

 occupation rejected on account of all diseases. 



Only one vertical column of totals is to be found in Table No. 20, and that is on 

 the exti'eme right of the pages of the last series, namely, from page 519 to page 523. 

 It shows the total number of men of all occupations rejected for each disease ; under 

 each subdi^^sion of diseases ; under each class of diseases ; and, finally, at tlie foot of 

 the last page (page 523) the number rejected on account of all diseases. The totals In 

 this vertical column correspond to additions of the totals on the horizontal lines, as in 

 all the tables.
