Whenthe entire periosteum has separated from the shaft, it carries?with it minute portions of the surface of the bone. Each ofthese is covered on its external surface by the periosteiun, onits internal by a layer of. granulations, the result of theorganized matter which originally filled the Haversian canals ;the gradual enlargement and subsequent blending of whichultimately allowed their vascular contents to combiae, with thelayer of granulations just described, to form the separatingmedium between the dead shaft and its minute Kving miaute separated portions, after having advanced some-what in development, appear, when carelessly examined, particu-larly in dried specimens, to be situated in the substance of theperiosteum, and ha
