as soon as its source of vitality is cut off by the destruction of the membrane, the progress of gangrene is arrested, and the root becomes exposed to that gradual destruction only, which is effected, on the one hand, by the action of the absorbents of the alveolar periosteum, in contact with it; and on the other, by the agency of heat and moisture externally.
