EXPLANATION OF TABLES. XXVII 



one of which contains the number rejected for each disease, and the other the appro- 

 priate ratio. By following a State or district through five double pages, the compara- 

 tive prevalence of disease in relation to locality may be observed. 



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

 the number of recruits and substitutes, in any congi-essional district and in the State, 

 rejected under a subdivision of diseases; the "Grand total" exhibits similar results for 

 the class of diseases; and the "Grand total for all diseases," which is found at the foot 

 of each list of diseases, shows the number of men rejected in each district, and in the 

 State, for all diseases. 



A vertical column of totals accompanies each State, and shows the total number of 

 men rejected in the State for each disease; for each subdivision, and for each class, of 

 diseases; and, finally, on the last page of the series, the number rejected for all dis- 

 eases. On the exti-eme right of the page of the last series, commencing at page 559, 

 is the column of "Grand total." This exhibits the total number of men (irrespective 

 of States or districts) rejected for each disease; for each subdivision, and for each class 

 of diseases; and, finally, at the foot of the last page of the table, page 767, the number 

 rejected for all diseases. 



Ratios. — The ratios throughout Table No. 23 accompany the totals and show 

 their relation to the whole number examined, as announced at the head of each column. 



Example. — On page 638 it will be seen that, in the State of Maine, for example, 

 61 men were rejected on account of phthisis pulmonalis. The ratio of this number of 

 rejected men to the whole number examined is seen to be 8.572 in the thousand. The 

 congressional districts furnished them in the following proportion : 



First congressional district 6 i 



Second congressional disti'ict 24/ . 



Third congressional district 2V> I^^J^cted on account of 



Fourth congressional district 4i l'^**"«^' pulmonalis.

Fifth congressional district 6 '

If phthisis pulmonalis be followed to the last series of States, namely, to pages 

 758-9, it will be seen that the total number rejected on account of this disease was 

 1,000; and the i-elation of this number to the whole number examined, namely, 305,068, 

 is expressed by the ratio of 3.272. Subdivisions and classes of diseases are to be 

 traced through the series of States in the same manner. 



If, in the case of the State of Maine, the relation of the State to disease be the 

 subject of inquiry, the columns headed by that State must be followed through five 

 consecutive double pages. Opposite each disease, each subdivision of diseases, and 

 each class of diseases, will be found stated the number of men rejected, and in the con- 

 tiguous column the ratio per thousand to the whole number examined in each district and 

 for the State. At the foot of page 646 will he seen the total number of men rejected in 

 the State of Maine for all diseases, namely, 2,533. The ratio of this number to the
