OF MOULIN-QUIGNOX. 607 



unworn. 3rd. The edges all round are sharp, fresh, and 

 unworn; or, if indented, the breaks are unequal, with crushed 

 fractures. 4th. The facets present more or less numerous, 

 broad and entire, residuary films, free from underlying ma- 

 trix. 5th. They are frequently finished by vertical blows on 

 the broad surface, to reduce some inconvenient salient in- 

 equality, leaving rude crushed fractures, which occasionally 

 present streaks of metallic iron. 6th. They are commonly 

 ruder in form, and an experienced eye will detect the differ- 

 ence ; but this indication is not to be relied on. 



The Flint-implements from Moulin-Quignon were of two 

 kinds. 1st. A few haches, and a corresponding number of 

 flakes, which were universally accepted as being unquestion- 

 ably genuine. The haches were rolled, highly weathered, and 

 uniformly deeply stained with iron ; polish vitreous ; facets 

 broad and shallow, without films ; ridges low and incon- 

 spicuous ; edges much worn and rounded. In short, they 

 presented more decided marks of age and rolling than most 

 of those found in the other localities of the Valley of the 

 Somme. The flakes were also tinged with iron, and equally 

 genuine and ancient in appearance. The majority of both 

 appear to have been got before the present year, and to have 

 been yielded by the ferruginous gravel. Not a single speci- 

 men of either, derived from the ' black seam,' was laid before 

 the Conference. 2nd. A large number of haches, without 

 the admixture, so far as I remember, of a single flake, and 

 all, when denuded of their matrix and well washed, present- 

 ing the most marked contrast to the genuine specimens from 

 the same locality. The English members of the Conference 

 produced about twenty, most of them procured within the 

 last three months, from the ' black seam ' or overlying 

 ferruginous gravel ; and a considerable or nearly equal number 

 was presented by the French members. When washed they 

 yielded the following characters : — Outline generally of the 

 spear-headed pattern ; a few oval or almond-shaped, and the 

 majority of them coarsely wrought, with a great sameness of 

 pattern, as if the production of one or two hands ; surface 

 with the dull appearance of a recent fracture, and without 

 glimmer, dendrites, incrustation, or patina of any sort ; 

 colour, even where greyish-white and porous, unaltered, and 

 substance perfectly free from ferruginous infiltration ; facets 

 conchoidal, with angular dividing ridges ; films numerous, 

 broad, and entire, without underlying matrix ; edges sharp, 

 continuous, not rolled, and either unindented, or where inter- 

 rupted showing recent angular fractures. Where a new frac- 

 ture was made before the Conference, the fresh surface differed 

 in no respect from that of the rest of the flint. Such at
