Therefore, the museum assemblage differs from natural ones in its greater number of blocked pore spaces, which will tend to lower the measured densities. For the larger and more porous parts, the wet weights and densities recorded in Appendix 1 are thus minimum esti- mates of these measures for naturally weathered bones. The original organic content of the hones. Aside from contributing to air entrapment in a bone, residual or- ganic matter probably does little to affect its overall weight and density. The density of cartilage is and tendon '(Currey, 1970:30). Other tissues have densities close to since they are composed primarily of water. A bone filled with water should have about the same weight as a bone filled with tissue, and after initial submergence, the two would have.
