But the time when justice would be done was to come at last. Dr. Falconer visited first Amiens and then Abbeville, to examine the deposits and the flints and bones found in them. In January, 1859, and in 1860, other Englishmen of science followed his example; and excavations were made, under their direction, in the massive strata which rise, from the chalk forming their base, to a height of 108 feet above the level of the Somme. Their search was crowned with success, and they lost no blue in leaking known to the world the results they had obtained, and the convictions to which these results lead led.16 In 1859 Prestwich announced to the Royal Society of London that the flints found in the bed of the Somme were undoubtedly the work of the hand of plan, that they had been found in strata that lead not been disturbed, and that the men who cut these flints bad lived at a period prior to the time when our earth assumed its present configuration. Sir Charles Lyell, in his opening address at a session of the British Association, did not hesitate to support the conclusions of Prestwich. It was now the turn of Frenchmen of science to arrive at Abbeville. MM. Gaudry and Pouchet themselves extracted hatchets from the Quaternary deposits of the Somme.17 These facts were vouched for by the well-known authority, M. de Quatrefages, who had already constituted himself their advocate. All that was now needed was the test of a public discussion, and the meeting of the Anthropological Society of Paris supplied a suitable occasion. The question received long and searching scientific examination. All doubt was removed, and M. Isidore Geoffroy-Saint-Hilaire was the mouth-piece of an immense majority of his colleagues, when he declared that the objections to the great antiquity of the human race had all melted away. The conversion of men so illustrious was followed of course by that of the general public, and, more fortunate than many another, Boucher de Perthes bad the satisfaction before his death of seeing a new branch of knowledge founded on his discoveries, attain to a just and durable popularity in the scientific world.
