CHART XXin. 



DISEASE. 



(Exclusive of" Conditions not necessarily associated with disease") 



The reason for excluding that class of conditions on account of which men were 

 found unfit for military service, but which cannot properly be considered as diseases, 

 is apparent. Chart XXIII, then, covers all causes of rejection which properly come 

 under the head of "Disease;" and its indications, proceeding as they do from such a 

 large number of observations, and including, all diseases, should, it would seem, be 

 looked upon as giving with truth the relation really existing between disease and the 

 various conditions of complexion, age, height, etc. 



Beginning with " Social condition," we find that the married men were more dis- 

 eased than the single, that is, a larger ratio was rejected ; but, as has been explained, 

 the married men were, as a rule, the older men ; and another division of the chart shows 

 that disease increases with age rapidly, and with remarkable regularity. It will be 

 noticed that, in regard to complexion, the "light" wei'e more affected than the " dark ;" 

 and this, as has been stated, is the rule. Men of the height " Gl and under 63 inches" 

 were found to be healthier than any others ; but those of the next division, " 63 and 

 under 65 inches," may be considered as almost equally so. This is largely, and perhaps 

 wholly, owing to the fact that they were, as a class, the younger men. The ratio of 

 rejection among those " undei- 61 inches" is unduly large, because many men who 

 were naturaUy of greater stature were, by reason of local injuries, etc., thrown, so to 

 speak, into this division. The division "No.tivity" will commend itself to careful 

 consideration. 



CHART XXIV. . 



CONDITIONS IN THEIR RELATION TO DISEASE. 



This chart, or rather table, is condensed from a number of the foregoing, and is 

 intended to show by numerals the i-elative position which each subdivision of each head 

 occupies in its relation to each disease or class of diseases. The larger numbei-s denote 

 the lesser prevalence of disease ; or, to simplify the matter, the larger numbers may be 

 considered as denoting greater health. A little careful study will enable the reader to 

 gather many interesting facts, which are shown more in detail in the foregoing charts, 

 and still more fully in Tables 16, 17, IS, and 19. 



As an example of the use of the table, let us take the two perpendicular columns 

 headed respectively "Conditions not necessarily associated with disease" and "All 

 diseases except ' conditions not necessarily,' etc." In the first of these, opposite " Mar- 

 ried," we find the figure 2, and opposite "Single" the figure 1. These indicate that 

 the married men were less affected by these " conditions," or were healthier, so far as they 

 are concerned. Under the head of age, we find the numbers running 1, 4, 6, /"), 3, 2, 

 which denotes that those under twenty years furnished the largest ratio of rejection, and 

 of course the smallest ratio of accepted men. In the divisions of heiglit and nativity,
