Bottyán, O.: The variations of the palatum with respect to sexual dimorphism I.

The rate of sexual dimorphism can be read from Figures 3 and 4 (similarly to the preceding Figs. 1, 2), and, with respect to age grouping, the increasing trend of the measurements up to the juvenile age group. The fluctuations of mean values as related to one another within the age groups older than the juvenile one in the given sex is not considered characteristic—in my opinion they are incidental as to cause.
