The right and left humeri are of practically the same length in the 
males, while in the females the average of the left bones is slightly 
inferior to that of the right, as is usual in most Indian tribes and also 
among the white and other races. The equal length of the arm bones 
in the males indicates probably a lack of specialized occupation. 
The dimensions of the shaft of the humerus at the middle and their 
percental relation or index are interesting in several respects, as 
shown by the following data:

In the first place it will be seen that although the Munsee arm 
bones are practically of the same average length as those of the 
miscellaneous American whites, their strength in both sexes, and 
especially in the males, is greater in the whites. It will further be 
noted that the disproportion is especially pronounced in the thickness 
of the bone, the humerus of whites, both male and female, being the 
stouter, as a result of which the shaft index is decidedly higher in the 
whites than in the Indians—the Munsee humerus, in other words, is 
more platybrachic. Much the same distinction exists between the 
Munsee humeri and those of the American negro; while on the other 
hand it will be noted that in this respect there is close harmony 
between the Munsee and other Indians. 
Referring again to the table on page 53, and contrasting the bones 
of the two sides, it will be observed that the left humerus in both 
sexes is on the average weaker, though the difference is quite small; 
also that the shaft index in both sexes is larger on the left side. 
Exactly the same conditions have been observed by the writer on 
the several series of arm bones of whites and negroes, and also on 
other Indians, as are presented in preceding tables, which fact shows 
that we are dealing with no accidental phenomena. The difference 
in the index between the two sides is due exclusively to the relatively 
greater breadth (i. e., the antero-posterior diameter) of the right 
bone, the thickness of the humerus being very nearly the same on 
the two sides of the body.
