Density of the Blackfish Petrosal

Article metrics


THE mammalian petrosal is generally recognized by anatomists as the most compact of bones. The physical density of the various bones does not seem to have attracted much attention. The only data in the literature available to me are those of the "Smithsonian Physical Tables", where the density of bone is given as varying from 1·2 to 2·0 gm. per cubic centimetre.
