The agreement above set forth might lead us to suppose that practically no racial differences are connected with the facets, at least between the whites and some of the Indians; but this assumption is not borne out by a detailed study of these characters. The next table shows the more detailed observations on the number and character of these facets in the Munsee and in whites, and also with reference to sex and side. Here we notice, in the first place, that the frequency of two facets only is much higher in both groups in the females than in the males, while three facets are correspondingly more frequent in the males. But we observe further that the condition of three facets in which the anterior and median are separated by a wide notch is very much more frequent among the whites than among the Indians.

As to sides, differences between the right and left are irregular; if we combine the two series of Munsee and whites they almost disappear.
