ANTIQUITY OF MAN.

by the ossified remnant of pulp and capsule. On one side of the crown (Plate III., c) a cavity has invaded the base of the enamel, in size and shape resembling that in the incisor. The crown of the premolar, p, has been still more worn; little of it is left above the fang; the worn surface is flat and polished, very feebly concave, becoming convex at the back border. The fang is solidified, as in the other two teeth.

In size these teeth, or what is left of them, equal the corresponding parts of the same teeth in the Australian ('Odontography,' plate cxix. fig. 2), and exceed that of the European figured in the same plate (fig. 3).

The condyle and tip of the coronoid process are broken off the portion of lower jaw (Plates II. &III. fig. 2). The angle of the jaw is rounded off, as usually seen in the edentulous jaw of aged individuals. The ridge on the inner surface beneath the place of the molar-sockets (Plate III. fig. 2) is well marked. The symphysis, s, does not project beyond the incisor-sockets. The prominences at the back part of the symphysis, for the attachment of the "genio-hyoglossus," the "genio-hyoideus," and the "digastricus" muscles, are distinct and well marked. The first form a pair, subcompressed, vertically extended, with an interval scooped out, as it were, between them. The subjacent pair of genio-hyoidean processes, of equal vertical extent, are narrower and closer together. From the more obtuse digastric rising extends a broad and shallow fossa; the rising itself supports a pair of ridges, smaller and more apart than those above. Behind the alveolar tract the rising portion of the mandible, to which some anthropotomists restrict the term "ramus," as contradistinguished
