XV] II EXPLANATION OF TABLES. 



relation tho total number rejected of a suhdivwion bears to the whole niunber examined 

 of the height speciiied at the top of the column ; and the ratios accompanying the 

 "Grand total" show the relation which the total number of men of a class of diseases 

 bears to the whole number examined, with the same pro\aso as to height. 



The ratios Avhich accompany the column of "Total rejected," on the right of each 

 page of the series illustrating the last degree of stature, refer throughout to the aggre- 

 gate number of men examined, namely, 501,068. 



Example.— If, for the sake of illustration, it be desired to ascertain the facts set 

 forth in this table respecting phthisis pulmonalis, it will be seen, on page 409, under the 

 column of "Number rejected," that 29 men (under 61 inches in height) were rejected 

 on account of that disease. 



The ratio of this number to the whole number of men examined who were of the 

 same height is 7.740 per 1,000. If the 29 men be traced back through the column 

 representing girth of chest, the following is the result observed : 



Under 29 inches 6^

In like manner, the details concerning phthisis may be followed through the next 

 degi'ee of stature on the same page, and through the successive degrees on ])ages 414, 

 419, and 424. On the right of page 424 will be seen, under the heading of " Grand 

 total rejected," the number of men of all dimensions of chest and of all degrees of 

 stature who were rejected on account of phthisis, namely, 5,044. The ratio that num- 

 ber bears to the whole number of men examined, namely, 501,068, is stated on the 

 next column at 10.067 per 1,000. If the total number ho traced through all the 

 degrees of stature, the following will be seen to be the result: 



Under 61 inches in height 29 



61 inches, and under 63 inches 132 



63 inches, and under 65 inches 428 



65 inches, and under 67 inches 1, 083

71 inches, and under 73 inches 519 



73 inches, and over 121 



Total number rejected 5, 044 



Each of the foregoing totals which represents a degree of stature may be traced 

 back in its six divisions denoting the degrees of girth of chest.
