The antiquity of the inhabitants of Gaul is now pushed back by the learned far beyond the days of Cæsar. M. A. Thieullen, in two communications addressed to the _Société d'anthropologie_ at Paris (January and February, 1898), maintained that the chipped flint arrow-heads found at Chelles and Saint-Acheul, which have been considered as the earliest works of prehistoric man, are, in reality, in common with the polished stone hatchets of the Neolithic age, the products of an industry in a high state of development, the result of successive essays by numberless generations. In this theory he is supported by other scientists, among them the English geologist, Prestwich; and in this insistence upon the artistic quality of the chipped and polished flints and the prodigious number of rudimentary utensils which have preceded and accompanied them is found another argument in favor of the great antiquity of man and his existence in the tertiary period. The soil of Paris has furnished many of these superior flints, and the comparative state of civilization to which the locality early attained is further testified to by the discovery, in the early months of this year, 1898, by an enterprising proprietor on the edge of the forest of Fontainebleau, of the site of a prehistoric pottery on his grounds. This locality, opposite the village of Ecuelle, was already noted for the menhir, or prehistoric upright stone, standing on the right bank of the canal. The ancient potteries seem to have occupied a space about five hundred mètres in length and two hundred in width; at the depth of sixty-five or seventy centimètres below the surface there is found "a black sand, burned, beaten down, trodden, which gives forth a resonant sound when attacked by the pick-axe; this arises from the fact that it has been, through a long series of centuries, tormented by the incessant passage of men and the innumerable fires of the furnaces." From the specimens of pottery extracted from this sand, it is concluded that this manufactory had been maintained from the Neolithic age down to the Gallo-Roman period. In the little village of La Mouthe, in the department of the Dordogne, farther south, have been discovered within the last few years, in a cavern, very curious and not unskilful outline drawings on the rock, sometimes touched up with color, of now extinct animals,--the extreme age of these works of art being demonstrated by the fact that they are in many cases partially covered with stalactites. The learned scientists who have uncovered and photographed these incised drawings conclude, from their appearance and from the fragments of animals' bones found in the cavern, that they are the work of men of the Neolithic age and the Palæolithic, which preceded it. In short, there is every reason to believe, on the strength of all the testimony which modern science has wrested from the unwilling records of the past, that
