DESCRIPTIONS OF THE PLATES STONE IMPLEMENTS. 39 



A. PLATE XII. 



Six roughly shaped specimens, in which an irregular cutting-edge has been 

 produced on some part of the margin by thinning it by bold parallel chippings on 

 one or both faces of the stone. Figs. 1, 2, and 4 are easily held in the hand, the 

 thick rough part against the palm ; and the curved edge is then exposed below 

 the closed fingers and thumb as a Scraper or Chopper : and in these specimens 

 that edge, as well as the other, bears some marks of use. The implements before 

 us are thus comparable in some respects with the larger " Choppers " described at 

 page 17. Figs. 3 and 6 have been roughly flattened and squared; the thinned 

 edge of the former (right-hand side of the figure) has been partly crushed by hard 

 knocks. Fig. 5 looks like the broad end of an axe-head. 



These were all found at the Moustier Cave, and have glazed surfaces. 



Fig. 1. An irregularly triangular piece of a rough, dark-grey, mottled flint-flake, 

 coarsely chipped on one face, so as to have a jagged cutting-edge on two 

 margins, both of which seem to have been somewhat worn by scraping or 

 cutting. A portion of the highest part of the ridge face has either been roughly 

 weathered, or, more probably, was so close to the original water-worn and 

 battered surface that it retains traces of its weathered condition. 



Fig. 2. A grey, mottled, somewhat heart-shaped flake, showing the " bulb of per- 

 cussion " on the inner face, at the obtuse projection ; trimmed on the convex 

 face by bold chipping so as to have a cutting-edge all round, except at the 

 thick corner where the "bulb" is. Both the curved and the straight edge 

 have been used. 



Fig. 3. A piece of translucent amber-coloured flint, retaining on one face the old 

 water-worn light-brown crust, and coarsely chipped all round on the other, so 

 as to have an irregular oblong shape with a rough angular edge, which is bruised 

 where thinnest (right-hand side of the figure). 



Fig. 4. Portion of a dark-grey mottled flint-flake (with Sponge-structure), retaining 

 part of the original, brown, worn crust, but otherwise so shaped by bold parallel 

 chipping as to have a roughly circular cutting-edge along two-thirds of its 

 circumference, the remainder forming a corner of two nearly straight solid 

 edges. The circular edge worn here and there by use.
