These axes were taken from theossiferous beds; one at four and a half metres, or nearly thirteen feet,and the other at nine metres, or about twenty-seven feet, below thesurface. The character of the soil and of the superposed layers ofcompact sand, free from any appearance of modern detritus, forbidsa supposition that they could ever have reached such a depth throughaccident since the formation of the bed itself, or by any infiltration from * Boucher de Perthes; p. 217-246. f Cuvier: Ossemens Fossiles. 360 GEOLOGY AND PALyEONTOLOGT, Section of the Gravel-Beds at Menchecourt.*Fia. * Modern, or rAlluvial. \ Diluvian, orClysmian ofBronqniart.

No doubt exists that those axes had lain inthe same position ever since the fossilized bones were there, or thatthey were brought thither by the same causes.
