DESCEIPTIONS OF THE PLATES STONE IMPLEMENTS. 37 



A. PLATE XI. 



Four lanceolate specimens, somewhat glazed ; three of them show, in crushed 

 and worn portions of their edges, evidences of "having been used. Fig. 4 is merely 

 a flake, with no modification of its edges. Figs. 1 and 3 also were flakes, but 

 have been dressed and used. Fig. 2 is almost symmetrical, chipped all over, 

 after the fashion of the many flint implements found in the gravel of the Somme 

 Valley and elsewhere : forms like the others, however, are not wanting in that 

 old gravel. 



Fig. 1. Roughly lanceolate flake of brown granular flint (Sponge-spicules, &c.), 

 truncate at the broad end, where the "bulb of percussion" and a large 

 conchoidal facet are well marked on the flat face, which is not shown in the 

 figure. The point at the other end has been broken off. Marks of use are 

 plain on the upper half of the left-hand edge of the figure, and also in the 

 hollows on either side of its upper end. 

 Le Moustier. 



Fig. 2. An acutely lanceolate implement of dark-grey flint, with Sponge-spicules, 

 &c., sharp at one end, roughly truncate at the other; more convex on one face 

 than on the other ; with the edges irregularly crenulate. Shaped by bold and 

 nearly parallel chipping, at a high angle, along the edges of one face. The 

 edge has some slight marks of use on either side of the point. 

 Laugerie Basse. 



Fig. 3. An acute-ovate implement, chipped out of a broad, mottled, grey flake, 

 having the " bulb " and roughly conchoidal face on the flat side (not figured). 

 Marks of use exist on the upper right-hand edge of the figure. The opposite 

 edge is less distinctly worn. The point is broken. 

 Le Moustier. 



Fig. 4. An amber-coloured, translucent, broad flake, with a largely conchoidal 

 under-face, struck off from a water-worn (battered and weathered) mass of flint, 

 that had been broadly facetted by former fractures. It has no artificial 

 chippings on the edges.
