The Periosteum.—Covering the surface of bone, except at the articular surface where it is covered with cartilage, is a membrane, the periosteum, which consists of two layers: an outer, fibrous, protective layer, and an inner, cellular, osteogenic layer. The outer layer consists principally of white fibrous tissue. The inner layer contains many more connective-tissue cells, which gradually be- come more closely aggregated as we proceed toward liie osseous surface; but there is no sharply defined line of demarcation between the,^^two periosteal Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Kaupp, Benjamin Franklyn, 1874-.
