The physical differences are essentially those of the physiognomy. The head is neither narrow nor scaphoid, or even very high. The Indian face is more prominent and more sculptured; that of the Eskimo appears fuller, especially in the lower part, and flatter. Part of this is due to the bony structure, part to the differing amounts of fat. An eversion of the angles of the lower jaw, which is relatively frequent and sometimes excessive in the Eskimo male while almost absent in the Indian, may give the Eskimo face almost a square appearance. Take with this the seemingly somewhat low Eskimo forehead, the not very widely open and somewhat on the whole more slanting eye, and the characteristic Eskimo nose with its rather narrow and not prominent nasal bridge, the ridiculous monk-like cut of the hair (in the older males), the often rather full lips with, in the males, a tuft of sparse mustache above each corner of the mouth; add to all this a mostly smiling or ready-to-smile "full-moon" expression, and it would be impossible to take the subject for anything else than an Eskimo. The Indian's face is more set, less fat, in the males at least, less broad below, with seemingly a higher forehead, sensibly made-up hair, not seldom a bit more mustache, and a nose that generally is both broader and more prominent. But the differences are less marked in the women and still less so in the children, especially where similarly combed and clothed. And there are, particularly on the Yukon, not a few of both Indian and Eskimo who even an expert is at a loss where to class. They may be due to old mixtures; no new ones are taking place; but it seems that there may be present another important factor, that of a far-back related parentage. In the color of the skin and eyes, in the color and nature of the hair, there is no marked difference between the two peoples of the Yukon. In stature the Eskimos are slightly higher.
