It is interesting to note that in the female Munsee tibia, type 1 is
decidedly frequent and much more common than in the males; type 3,
which is usually associated with considerably developed leg muscles,
is absent in the females; type 4 is relatively frequent in both sexes;
type 6 is wholly absent.
In the next table are shown for comparison the proportions of the
different types found by the author in different racial groups. For the
purpose of elucidating these data, both sexes are taken together. It
is seen that well-differentiated type 1 is most common in the Indians;
that type 2 is relatively scarce in the negro; type 3, most common in
the white (laboring class), was not met with in a pronounced form in
the negro; type 4 is decidedly more common in the Indian than in the
other two races; and type 6, absent in the Indians and rare in the
whites, is fairly frequent in the negro. These differences show that
the shape of the shaft of the tibia, as that of the femur, humerus, and
other bones, has a considerable racial significance, which, as our data
are increased, will doubtless become accentuated.
