Dupont to be of the same age as the contents of the caves close by the Trou des Nutons and Trou Rosette, which have been inhabited by palæolithic savages. The following is the section (Fig. 69) which he gives of the deposits. Close to the river Lesse is the alluvium (No. 1), below which is a clay (No. 2), with angular blocks passing upwards under the rock shelter, and filling the cave. Under this is a stratum of loam (No. 3), resting on gravel (No. 4). Sixteen human skeletons were discovered in the sepulchral cavity (S), at the mouth of which was a large slab of rock (D), by which it was originally blocked up. A singular urn, with a round bottom and with the handles perforated for suspension, was found at the entrance, together with flint flakes, ornaments in fluorine, and eocene shells perforated for suspension. Outside, at the points H H, was an accumulation of broken bones, belonging to the lemming, tailless hare (Lagomys), beaver, wild cat, boar, horse, stag, urus, chamois, goat, and other animals, birds and fishes. From the occurrence of fragments belonging to two reindeer, it is considered by M. Dupont to belong to the reindeer age. The old hearth was close by, at F (Fig. 69).
