[76] Type 1=horizontal or but slightly inclined; 2=moderate to medium obliquity; 3=pronounced obliquity; 4=deep saddle-shaped; 5=semilunar; 6=convex; 7=markedly concavo-convex.

[77] In two specimens (2 per cent) the form of the border was unclassifiable.

The data obtained in this particular on the Munsee and other Indian groups, as well as on a large series of whites, are given in the next table. It is very evident that racial and tribal differences of some importance exist in the shape of the border. Among the whites its most common form is type 2, or moderate to medium oblique, pronounced obliquity being infrequent; types 4 and 5 occur but rarely. In the Munsee there is a curious but doubtless local prevalence of the semilunar type 5, the next most frequent form being that of pronounced obliquity; and one-fourth of the cases show the saddle form or an approach to it. Among other Indians the conditions differ. The cliff-dwellers of southern Utah come, on the whole, near to the whites; among the Mexican Indians low borders prevail, while among the Northwest Coast tribes we find the opposite condition—high borders, with a relative frequency of the angular or saddle-shaped type (4 or near 4). It is an interesting fact that the last named form (4) is frequent and often highly developed in the Eskimo.

The question occurs as to how the form of the superior border differs in the two sexes and on the two sides, and the next table throws some light on these problems. It will be observed that among the Indians the differences between the males and the females are not striking, though there is a tendency toward greater obliquity of the border in the males. Among the whites, types 1 and 4 are more common in the females than in the males; type 2 occurs about the same number of times in the two sexes, while types 3 and 5 are more frequent in the males.
