The relics found in the interior of the sepulchral cave of Aurignac have led to a very remarkable inference, which shows how interesting and fertile are the studies which have been made by naturalists on the subject of the antiquity of man. The weapons, the trophies, the ornaments, and the joints of meat, placed by the side of the defunct--does not all this seem to establish the fact that a belief in a future life existed at an extraordinarily remote epoch? What could have been the use of these provisions for travelling, and these instruments of war, if the man who had disappeared from this world was not to live again in another? The great and supreme truth--that the whole being of man does not die with his material body is, therefore, innate in the human heart; since it is met with in the most remote ages, and even existed in the mental consciousness of the man of the stone age. An instinct of art also appears to have manifested itself in the human race at this extremely ancient date. Thus, one of the articles picked up in the sepulchral cave of Aurignac consisted of a canine tooth of a young cave-bear, perforated so as to allow of its being suspended in some way or other. Now this tooth is so carved that no one can help recognising in it a rough outline of some animal shape, the precise nature of which is difficult to determine, although it may, perhaps, be the head of a bird. It was, doubtless, an amulet or jewel belonging to one of the men interred in the cave, and was buried with him because he probably attached a great value to it. This object, therefore, shows us that some instincts of art existed in the men who hunted the great bear and mammoth.

The first six species are extinct; the others are still living:-- The great cave-bear (_Ursus spelæus_); the mammoth (_Elephas primigenius_); the rhinoceros (_Rhinoceros tichorhinus_); the great cave-lion (_Felis spelæa_); the cave-hyæna (_Hyæna spelæa_); the gigantic stag (_Megaceros hibernicus_); the bison, the reindeer, the stag, the horse, the ass, the roe, the wild boar, the fox, the wolf, the wild-cat, the badger, and the polecat.
