Age changes in the pubic bone

Abstract

In the first contribution to this subject (7) I discussed a t some length the age changes occurring in the pubic bone of the male White after the eighteenth year.In that communication I explained that individuals of one human stock and sex were taken in order to obtain, so far as possible, a standard by which comparisons could be made with other stocks, with the female sex, and with Primates in general.The observations showed that there is a definite metamorphosis going on in the pubic bone throughout life, and that this metamorphosis has a fairly precise age-relationship which I summarized in the following manner:Age 18-19.Phase 1:-Typical adolescent ridge and furrow formation with no sign of margins and no ventral bevelling.for Part I see No. 3, VOL.
