Lectures on the operations of surgery : and on diseases and accidents requiring operations . gradually increases in size, and perhaps in-volves the gums of the adjoining teeth. Some of these swellingsare as hard as the gum ; some are soft and pulpy, and bleed on aslight touch ; and some, again, though very seldom, assume a malig-nant character. These tumours are generally of a benign nature,they are firm in their consistence, and, if thoroughly extirpated, arenot reproduced, but if any portion is left, they return. If the socketof the tooth, in which the disease commenced, is not taken away,and indeed the whole gum, the disease is sure to come back in afew months, following the analogy of tumours in other parts.
