^{page 288 note a} Since the publication of the report of this Paper in the Athenaeum, there has been some correspondence in that and other journals upon the question whether these implements were of human or natural origin, which called forth the following expression of opinion from Professor Eamsay, a thoroughly competent judge ia such a matter: “For more than twenty years, like others of my craft, I have daily handled stones, whether fashioned by nature or art, and the flint hatchets of Amiens and Abbeville seem o t me as clearly works of art as any Sheffield whittle.”-(Athæneum, July 16,1859.)

^{page 298 note a} Since the reading of this paper, Amiens and Abbeville have been visited by many geologists of note, and, among others, by Sir Charles Lyell, who, in his address to the Geological Section of the British Association, at their meeting in 1859 at Aberdeen, expressed himself as fully prepared to corroborate the observations of Mr. Prestwich. M. Gaudry, and M. Pouchet, of Eouen, on the part of the French Académie des Sciences, and the town of Eouen, have also made researches at Amiens, and have both been successful in discovering specimens of the implements in trenches made under their own personal superintendence.-(Comptes Rendus, tom. 49, No. 13, and Eeport of M. Pouchet.) See also the Address of Lord Wrottesley to the British Association, at Oxford, in 1860. Some few other facts that have come to my knowledge since this paper was read have been incorporated in the text.

From his account it seems to have been found with a skeleton of an elephant in the presence of Mr. Conyers.
