Following recording and the construction of models, the patterns of labial furrows obtained of one randomly subjects from Europids , Mongoloids, and Negroids were registered on the basis of various systems of classification. Typification was carried out with the help of a reflected light microscope (10-fold magnification). The mathematico -statistical evaluation of the material was made by contingency analysis. The distribution pattern of labial furrows observed in test persons of the mongolian-type population was found to be clearly differentiated from that seen in representatives of the european-type and negro-type population who showed resembling distribution patterns.

10 selected midfacial dimensions were measured on each of 711 skulls from 4 anthropologically different populations and tested for their usefulness for the characterization of populations. The palate height cannot be recommended as a distinctive feature because of its considerable variability within the single groups. According to the problems under study, sagittal, and transversal midfacial dimensions are suited for classification into groups.

4,497 maxillary teeth from 711 skulls were examined and measured. The diameters of the single teeth as well as the sums, quotients, and indices were subjected to statistical treatment using univariate procedures. Clear-cut differences among anthropologically different populations (Europoids, Negroids, Mongoloids, Melanesoids) were evidenced by the tooth dimensions. The indices are suited for revealing specific relationships among tooth groups.
