[Sexual dimorphism of correlations in crainometry].

The correlations of the 20 main cranial dimensions, in 2 series of 500 male and 500 female subjects are often higher in man than in the women. This result confirms Schreider's former statement. Through partial correlations, we keep constant the two main sexual characteristics of the skull (weight and volume) : the sexual differences of partial correlation are then in equal number in each sex, Schreider's hypothesis being thus confirmed : sexual dimorphism is partly genetical and related to sex.
