Note 36 — DISSERTATION II. CONTINUED.
Reading edition
When a bone becomes carious, the periosteum is completely detached, and, therefore, it is felt to be rough by the probe. Its colour becomes first of a dull white, or dirty yellow, which it either preserves, or changes for the intermediate hues betwixt these and black. It is generally more porous than formerly, and lighter; but these qualities vary, from very slight degrees, to the appearance of a light coralline.
