The new acetabulum, formed in the foramen ovale, inwhich the head of the thigh-bone was contained, and inwhich it was so completely enclosed, that it became im-possible to remove it, unless a portion of the new socketwere broken away. It was lined by a ligamentous sub-stance, on which the head of the bone moved to a consi-derable extent I. The original acetabulum, situated above the level, and tothe outer side, of the new cavity.

The new acetabulum formed in the foramen ovale, a deepossific edge surrounding it; its internal surface is ex-tremely smooth. The ligament of the foramen ovale hasdisappeared, and ossific matter has been deposited in itsstead D. The thigh-bone removed, and the portion of the new acetabulum is shewn, which was obliged to be broken offto separate the thigh-bone from its new socket E. Head and neck of the thigh-bone; the former a little changed by absorption, and the latter by ossific deposit.
