Abstract:
:Angular and linear measurements of maxillary first molar occlusal polygons are given for young San (Bushmen), Sotho, Asiatic Indians, Whites, and Papago Indians. Angular and linear measurements are inseparably related. Much greater variation occurs in widths than in lengths. Maximum variation occurs between San and Papago. Papago maxillary first molars are separable from Old World molar samples in two of four angles and eight of 13 indices.
