Fig. 21. Cat. no. , P. M. Rabah. (Figure shows convex face.)
Flint — light — opaque. Patina ■— concave face, yellow brown — convex face, dendritic. 7 X
5X2 cm. Concave face — single cleavage surface with cone of percussion at A. Convex face —
several radial facets, so arranged that the greatest thickness of the implement comes at E.
Rough retouching occurs around the entire edge on the convex face. The imple-
ment is ovoid, with end D slightly pointed. Shallow notches worked on the concave
face occur at B and C.
Fig. 22. Cat. no. , P. M. Rabah. (Figure shows an edge.)
Flint — opaque. Patina — brown. 8 X 5.5 X 1.5 cm. Flaking on both faces longitudinal, with
a portion of the cortex remaining at one end.
End A has a surface nearly at right angles to the two faces, and two small notches,
probably for finger holds. The edge is but a little more sinuous than that of many other
specimens in the collection.
Fig. 23. Cat. no. , P. M. Rabah. (Figure shows concave face.)
Flint — light — very translucent. Patina — concave face, yellow brown, thickly mottled —
convex face, light yellow. 9X6X1 cm. Concave face ■— single cleavage plane with cone of per-
cussion at end A. Convex face — several longitudinal facets.
End A has had a flake removed at right angles to the two faces. The remainder of
the edge is carefully retouched, mainly on the concave face. At B is a well-worked
shallow notch, and at C, two small notches having a point between them. End D is
straight, and slightly oblique. The whole specimen is roughly rectangular.
Fig. 24. Cat. no. yf5-, P. M. Rabah. (Figure shows convex face.)
Flint -— light — opaque. Patina ■— concave face, yellow brown — convex face, dendritic. 9 X
5 X 1.5 cm. Concave face ■— portion of a single cleavage plane. Convex face — cleavage has followed
old fracture lines (incipient fractures).
The edges, except at A, are carefully retouched on the convex face. At E is a flat
facet nearly at right angles to the two faces. At B is a carefully worked notch, and at
C a projecting point. The end D is rounded. The notch at A seems to be due to a late
accident, and is therefore without significance. As a front scraper, the implement would
apparently be handled much more easily with the left hand than with the right.
Fig. 25. Cat. no. 7q5 , P. M. Rabah. (Figure shows convex face.)
Flint — light — translucent. Patina — concave face, yellow, somewhat mottled in spots —
convex face, dark dirty brown, mottled. Incrustation — calcareous in spots, on both faces. 14 X 7 X
2 cm. Concave face — single cleavage plane with cone of percussion at A. Convex face — either
old fracture surface, or else facets which have followed the lines of incipient fracture.
