摘要：
Four factors controlling the dimensions and shapes of the cranial bones are distinguished: (1) Factor of homology, measured by correlations between corresponding lengths and indices of homologous bones. The mean correlation for lengths is 0.82, for indices 0.74. (2) Factor of size, measured by correlation of lengths on different bones on the same side, or on heterologous bones on opposite sides. The mean cor-relation is 0.18. (3) Factor of shape, measured by correlation between indices of bones. This is 0.04 lor noncontiguous and 0.07 for contiguous bones, showing that there is (4) a Factor of contiguity. The factor of homology thus is much the most important. The face is more symmetrical than the brain-case. The coefficient of variation over-corrects for size. The coeffcients of variation of absolute lengths are least in the sigittal, intermediate in the transverse, and greatest in the verti-cal direction, i.e., the laying down of a given bone of an individual skull does not proceed equally in all direc-tions. If further research shows that the characters of individual bones are racially differentiated, they will be more suited for use with the coefficient of racial likeness than the characters of the whole skull hitherto used.
