[Distribution of the labial red furrow patterns].

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.
