If we compare the industries, still very modest, with those of the present day, we shall be able to form for ourselves an approximate idea of what the race of Canstadt was when it occupied perhaps nearly the whole of Europe. With M. Lartet we see in the obsidian lances of New Caledonia, the flint heads of the lower alluvium of the Somme; the hatchet of certain Australians reminds us, as it did Sir Charles Lyell, of the Abbeville hatchet. It is with the latter and with the Bosjesmans, that I should be tempted to connect the Neanderthal man and his fellows. Like them, he seems to have most frequently led a wandering life. But few of his dwellings, or places of meeting, are known to us, such as the Naulette cavern. Nothing seems to indicate that he had places of burial such as we find later. Everything tends to show, moreover, that he lived entirely as a hunter, and there is nothing to justify us in supposing that he was acquainted with agriculture, which is carried to such a remarkable pitch by certain Melanesian negroes. IV. Judging from the geological distribution of the remains which have been met with up to the present time, the Canstadt race during the quaternary period principally occupied the basins of the Seine and the Rhine, and extended perhaps as far as Stängenäs in the Bohuslän; certainly as far as the Olmo in central Italy; as Brux in Bohemia; as the Pyrenees in France, and probably as far as Gibraltar. This race is not restricted in point of geological time. The attention roused by the strange characters of the Neanderthal cranium was the means of instituting widespread investigations, which have rapidly drawn this specimen from the isolation in which, at first, it seemed to be placed. B. Davis, Busk, Turner, King, Carter Blake, Pruner Bey, Vogt, Huxley and Hamy have been particularly successful in these investigations, and have brought to light relations which are now generally adopted. The result obtained from all these labours is that the Canstadt type, sometimes remarkably pure, and sometimes again more or less modified by crossings, is found in the dolmens and in the cemeteries of the Gallo-Roman period, in those of the Middle Ages, and in modern tombs from Scandinavia to Spain, from Portugal to Italy, and from Scotland and Ireland to the valley of the Danube, in the Crimea at Minsk, and as far as Orenbourg in Russia. This area of habitation comprises, we see, the entire space of time which has elapsed from the quaternary period to the present day, and the whole of Europe.
