Data from serial radiographs of 40 children were used to study the rates of total, diaphyseal and epiphyseal elongation of the bones of the hand from 3–13 years. Communality indices were calculated from complete correlation matrices for each sex. These indices tended to be lower for boys than girls. Communality indices for distal phalanges were lower than for the other bones and those for epiphyseal elongation were lower than those for total or diaphyseal elongation. Correlations between groups of bones in their rates of elongation were higher in rows of bones than in rays. There were statistically significant neighborhood effects and a slight tendency to marginal effects in the correlations between rates of elongation in rows of bones; neither of these effects was present in rays.
