A. PLATE XXIV. 



We have here a series of two sorts of those Implements termed "Scrapers"*, 

 such as wholly occupy A. Plates VII., X., and XIX. and occur also in some of 

 the other A. Plates, being dressed portions of flakes, with either more or less 

 oblong or more or less ovate outline, and having either one or hoth ends neatly 

 dressed to a semicircular or elliptical edge. None on this Plate have had the 

 tang produced by sharp lateral fracture of the edges, like most of those in 

 A. Plate VII. Some " Scrapers " appear to have been used at one end or the 

 other ; but others have their ends unaffected by wear, whilst one or both of their 

 lateral edges have been much worn. See also pages 22, 35, 83, 85, &c. In this 

 Plate, figs. 1-9 have only one end broadly rounded with the usual solid edge, 

 the other end either tapering to a blunt point, or reduced to a narrow irregularly 

 rounded apex, its lateral edges having been chipped away towards the narrow 

 end more or less symmetrically. In either case the shape of the original flake 

 has frequently had an influence in determining the formation of these tapering, 

 acute-ovate, or pear-shaped Scrapers ; and a remnant of the bulb of percussion 

 is sometimes still present, especially in figs. 1, 2, 4, and 6, though of course not 

 visible on the surfaces (ridge-faces) shown in the Plate. All the specimens 

 figured here are more or less arched. 



It is impossible to make a distinct separation between the tapering and the 

 oblong forms : thus fig. 11 has, and figs. 5 and 12 probably have had, neatly 

 rounded solid edges at each end; and the unequal size of the ends in these 

 Double Scrapers alone separates them from the more symmetrically oblong 

 specimens. 



The Implements figured on this Plate show more or less the effects of weather- 

 ing, either in discoloration or glazing of the surface. 



Fig. 1. Dark-coloured spicular flint. Obliquely acute-ovate; slightly worn on 

 the oblique side and rounded end. 

 From Laugerie Basse. 



Fig. 2. Dark-grey spicular flint, retaining a portion of the crust of the narrow 

 end. High -backed and rough ; worn at the round end. 

 From Les Eyzies. 



* Also termed " Thumb-flints " by English archaeologists, who find analogous implements, both on the 

 surface and accompanying very old burials, in Yorkshire and elsewhere.
