Another fact, upon which M. Dupont has with justice insisted, adds to the probability arising from various considerations, of our being right in attributing to these quaternary men a kind of religion more or less analogous to Fetishism. In the Trou de Chaleux, a mammoth’s ulna was placed by the side of a hearth upon a slab of sandstone. Now the mammoth no longer existed in Belgium at the close of the age of the reindeer, and this bone must have been found in the alluvium of the preceding age. It had doubtless been the cause of an error which may be observed even at the present day, and had been looked upon as having belonged to a giant. The place of honour which was allotted to it in the dwelling of the troglodytes seems to intimate that it had become an object of veneration. IX. Very few remains of the two races of Furfooz and that of Grenelle, have been discovered in other quaternary deposits than those which have just been mentioned. The former are, however, represented in the basins of the Somme and the Aude; the latter has been met with at two or three points in the basin of the Seine. We have seen that it existed at Solutré, and the skull of Nagy-Sap in Hungary must probably be referred to it. These facts are sufficient to show that since the glacial epoch the races in question have occupied an extensive area. In the neolithic age, we find the mesaticephali of Furfooz extending from the Var and Hérault to Gibraltar; the sub-brachycephali are represented from Verdun to Boulogne-sur-mer, and to Camp-Long from Saint-Césaire; they intermingled with the ancient inhabitants of Cabeço d’Arruda in Portugal. The brachycephalic race of Grenelle, has, however, left the most distinct traces. It has been discovered in France in several dolmens, and in the Round Barrows in England. In Denmark it constitutes the brachycephalic type of Eschricht, and in Sweden forms a dozen of the total number of the skulls found in dolmens by Retzius and his successors. The intervention of these different races in the formation of existing races is equally evident. The exact demonstration of the fact is, however, often difficult. The crossing which took place between groups placed in such close contact with each other, more or less confused the types. Other brachycephalic types, amongst others the Celtic race, such as it has been described by M. Broca, came to add to the confusion. Nevertheless, when visiting the valley of the Lesse, several members of the Congress of prehistoric Anthropology recognised skulls and faces as bearing in the clearest manner, the distinctive marks of the local fossil races, and these traces are still more frequent in the rural population which supplies the markets of Antwerp.
