MOULIN QUIGNON  , a quarry near Abbeville, France, celebrated for the discovery in 1863 by Boucher de Perthes of a human jaw-bone believed to be referable to the Quaternary period . By his collection of flints Boucher de Perthes had been the first to attempt to establish the existence of man in remote ages; but it had been objected that if the flints were indeed the work of man, human remains would have been found in association with them . Considerable excitement therefore was created both in England and France by the " find " of bones at Moulin Quignon, and a commission of inquiry was appointed . The report was favourable to the genuineness of the relics, but latterly doubts have arisen as to whether they can be regarded as earlier than the Neolithic age .
