There was no one in England whose authority deserved to have more weight in overcoming incredulity in regard to the antiquity of the implements in question than that of Mr. Prestwich, since, besides having published a series of important memoirs on the tertiary formations of Europe, he had devoted many years specially to the study of the drift and its organic remains. His report, therefore, to the Royal Society, accompanied by a photograph showing the position of the flint tool in situ before it was removed from its matrix, not only satisfied many inquirers, but induced others to visit Abbeville and Amiens; and one of these, Mr. Flower, who accompanied Mr. Prestwich on his second excursion to St. Acheul, in June, 1859, succeeded, by digging into the bank of gravel, in disinterring, at the depth of twenty-two feet from the surface, a fine, symmetrically shaped weapon of an oval form, lying in and beneath strata which were observed by many witnesses to be perfectly undisturbed.
