The total number of radii in condition to be measured is 41, 19 male
and 22 female. Taking the paired bones in the males, we find that their
length is equal on the two sides, as was very nearly the case with the
humeri; in the females the right radius averages slightly longer than
the left, again as in the arm bones of this sex. The arms as a whole
were therefore of very nearly the same length on the two sides in the
males, but the right was generally slightly longer than the left in the
females, a condition which in all probability was connected with the
relatively greater use of the right hand and arm in the latter sex.
The percental relation between the length of the radius and that of
the humerus approximates 79 on both sides in the males and 78 in the
females. Indians of other localities show much the same condition, the
index approximating in the males 78 on both sides and in the females 77
on both sides. In whites the same index is only 73.6 in the males and
72.8 in the females; while the American negro gave to the writer 77.4
for the male and 76.8 for the female sex. This means that the forearm
in the Munsee and in Indians generally is relatively long; it is
decidedly longer in relation to the humerus than in the whites, and so
far as the Munsee are concerned it is even slightly longer than in the
average American negro; and in all the groups it is to a slight extent
relatively longer in the males than in the females.
In strength, curvature, and other features the Munsee radii show
nothing exceptional. In fact, this bone is of secondary importance in
the anthropology of modern races except in its relative proportions.
