Over the whole inclosure of these ancient camps worked flints and remains of pottery have been found--objects which are sufficient to testify to the former presence of primitive man. The enormous ramparts of these camps also tend to show that pre-historic man must have existed in comparatively numerous associations at the various spots where these works are found. If we were to enter into a detailed study of the vestiges of the polished-stone epoch existing in the other countries of Europe, we should be led into a repetition of much that we have already stated with regard to the districts now forming France and Belgium. Over a great portion of Europe we should find the same mode of life, the same manners and customs, and the same degree of nascent civilisation. From the scope, therefore, of our present work, we shall not make it our task to take each country into special consideration. We will content ourselves with stating that the caves of Old Castille in Spain, which were explored by M. Ed. Lartet, have furnished various relics of the reindeer and polished-stone epochs. Also in the provinces of Seville and Badajos, polished hatchets have been found, made for the most part of dioritic rocks. Numerous vestiges of the same epoch have, too, been discovered in various provinces of Italy. We give in fig. 128 the sketch of a very remarkable arrow-head found in the province of Civita-Nova (the former kingdom of Naples). It is provided with a short stem with lateral grooves, so as to facilitate the point being fitted into a wooden shaft. [Illustration: Fig. 128.--Flint Arrow-head, from Civita-Nova (Italy).] Elba, too, was surveyed by M. Raffaello Foresi, who found in this Mediterranean isle a large quantity of arrows, knives, saws, scrapers, &c., formed of flint, jasper, obsidian, and even rock crystal. There were also found in the Isle of Elba workshops for shaping flints. Great Britain, Wurtemburg, Hungary, Poland, and Russia all furnish us with specimens of polished stone instruments; but, for the reason which we stated above, it would be superfluous to dwell upon them. We shall now pass on to an examination of the type of the human race which existed among the northern nations of Europe during the polished-stone age. There is a cavern of Ariége which belongs to the polished-stone epoch, and has been explored by MM. Garrigou and Filhol--this is the cavern of _Lombrive_, or _des Echelles_; the latter name being given it because it is divided into two portions placed at such very different levels that the help of five long ladders is required in order to pass from one to the other. This cave has become interesting from the fact that it has furnished a large quantity of human bones, belonging to individuals of both sexes and every age; also two entire skulls, which M. Garrigou has presented to the Anthropological Society of Paris.
