CIRCUMFERENCE OF CHEST. 



33 



If girth of chest bear a regular relation to height, and height be always deter- 

 mined by race, then it could hardly be anticipated that in this country the artificia] 

 divisions of States, with their restless, mobile population, would be likely to present 

 any evidence of a law in the matter. But if the arrangement by States be discarded, 

 and the whole of the series of the white natives of the United States be examined, a 

 very different result is obtained. Then it will be seen that the girth of the chest 

 increases as the height extends with a regularity that would almost admit of a calcu- 

 lation by arithmetical progression being substituted for the observed results. The 

 nativities presenting the largest number of observations have again been selected in 

 order to illustrate this condition.
