Injuries and diseases of the jaws . eum of the College of Surgeons of England,has been especially investigated by ^Mr. Salter (Guys Hos-pital Reports, 1869), who believes that the outgrowthis due to hypertrophy and dilatation of a fang,and not, as was formerly supposed, to hypertrophy of thecementum.

The outer layer is composed ofcementum, or tooth-bone, and within this is a layer of truedentine, which is wanting below; and within this again is the nucleus of calcified tooth-pulp. This last is composed ofa confused mass of bone-structure and dentine-structure,arranged around and separating an elaborate vascular net-work of the same character as that of the dentinal pulp.
