the same rule holds good — the larger figures denoting the more healthy height or 

 nativity. 



The second of the two coluuuis chosen for illustration shows the relation of these 

 five conditions of life to disease proper as a whole, and is of far greater interest. It is 

 simply a summary of Chart XXIII placed in juxtaposition with other tabular sum- 

 maries for comparison. It shows by the numerals : — that the single men were healthier 

 than the married ; that the men of dark were healthier than those of light complexion ; 

 that the youngest men, exclusive of those under suitable age or deformed, were health- 

 iest ; and that disease increased steadily with increase of age. The same is true in 

 i-egard to height, except that those under sixty-one inches, as a class, w^ere not as healthy 

 as those two and four inches taller. Of all nativities, the Indians of the United States 

 were found most healthy, they being affected l)y but few of the diseases common among 

 civilized men ; and it may be proper to note here that the only diseases on account of 

 which any of them were rejected are syphilis, scrofula, diseases of the eye, and chronic 

 disease of the bones. 



It wnll be noticed that Mexico furnished a greater ratio of rejection than, any other 

 country, followed next in order by Germany, Poland, Holland, Spain, Hungary, France, 

 etc. As regards nativity, it will be observed that in all the charts the order of aiTange- 

 ment is in accordance with the greater or less prevalence .of the disease — the position 

 of each nativity in the list being determined by the ratio rejected — and the figures or 

 numerals of this table indicate the luimerical position of each nativity under each disease 

 or class of diseases. Sometliing remarkable is the close grouping and mean position of 

 the natives of English-speaking countries. In the list of twenty-four nativities, the 

 mean falls, of course, between 12 and 13, and we find England represented by the 

 number 12, and the United States (whites) by 13. Departing from the mean on either 

 side, we find Wales as number 11, and Scotland as number 14, while Ireland is num- 

 ber 10. Thus these five nativities are represented by the consecutive numbers 10, 11, 

 12, 13, and 11. It may be supposed that a greater number of men of these nativities 

 were examined, and that therefore they would naturally show a mean ratio of rejection, 

 because when the nmnber examined is small, the rejection of but a single man may 

 vary the ratio very much ; but the number of Germans examined was greater than the 

 number of Irishmen, the luimber of colored men exceeded the number of Enalishmen, 

 the British Americans' were in excessof the Scotchmen; and the Frenchmen, Norwegians, 

 Swiss, and Swedes, in each case outnumbered the Welchmen. 



Further study of this table will reveal many interesting features of the preceding 

 charts. 



CHARTS OF CLASS II. 



(XXV TO XXXIV, INCLUSIVE.) 



The charts of Class II, which are intended to show the relation of diseases to 

 occupation, so completely explain themselves that only a few general remarks, touching 

 the divisidiis adopted and some unexpected indications, are necessary. The division of 

 all. occupations into four groups or classes is of course a somewhat difficult matter,
