总结
死后，年龄为 46-92 岁的 24 名女性和 26 名男性从桡骨和无齿下颌骨中切除了 3-4 厘米长的横向节段。为了获得两种不同骨骼中矿物质的密度值，应用阿基米德原理确定了样本的比重。在个体内部，比重与年龄成反比变化（P<0.01）。在这方面，下颌骨和整个材料的半径之间也存在统计相关性（P <0.0l）。
summary
Transverse segments 3–4 cm long were excised post mortem from the radius and from the edentulous mandible in twenty-four females and twenty-six males, aged 46–92 years. In order to obtain a value for the density of the minerals in the two different bones, the specific gravities of the specimens were determined by application of Archimedes' principle. Intra-individually, the specific gravity was found to vary inversely with age (P <0.01). A statistical correlation was also found in this respect between the mandible and the radius in the material as a whole (P <0.0l).
