The necks of the Teeth are closely invested and protected by the Gum, which is highly vascular, a vermillion substance, of a peculiar nature, protecting also the alveoli, or sockets of the Teeth, and capable of bearing extreme pressure, without injury to its circulation, or inducing that kind of inflammatory action, which takes place in other soft solids, when ex- posed to similar causes. 3rdly. The alveolar processes, which are of a yielding and elastic nature, are formed entirely for the reception of the Teeth, and, along with the Gum, are intended to pre- vent injury from concussion, which would otherwise arise. These processes, after
