tooth), together with a few other species. The worked implements of ordinary stone were in considerable abundance, and consisted of hammers and throwing-missiles, the former being quartz pebbles, while the latter were roughly rounded from limestone rock. The flint industry was represented by nuclei, knives, scrapers, borers, and discs worked on both sides. Of bone and horn there were cut portions, supposed to have been used as anvils, while others were utilised as implements of some kind, and others were perforated with a round hole.
The deposits formed an upper and a lower stratum. The

latter consisted of a consolidated breccia of reindeer bones, worked flints, etc., and in it were found all the fragments of human jaws, but not in the same place. In the same stratum were also the larger and older flint implements, such as the oval coup-de-poing types. The upper was characterised by the preponderance of reindeer remains and industrial objects of bone and horn, said to belong to the Aurignacien epoch.
The upper fragment of a human jaw discovered at once showed that, in point of the straight chin and massiveness of structure, it could be paralleled with that of Naulette. According to Professors Siffre and Gaudry, to whom the fragment had been submitted, it belonged to a young subject from fourteen to eighteen years of age. The first and second molars were in their sockets, but-the third or wisdom tooth had not yet emerged from the alveolar border (see A in Fig. 43). A
