A description is given of POLL'S triangular coordinate system, and the advantages of this form of graphical representation of dermatoglyphics indicated. When the different populations of the world are plotted in POLL'S triangle, the advantages of FURUHATA'S index over DANKMEIJER's index become readily evident. Nevertheless neither of these indices nor the index of pattern intensity-by themselvesprovide adequate means of differentiating different population groups, or of determining their affinities.
