Fig. 14. Cat. no. , P. M. Rabah. (Figure shows convex face. Cf. enlarged portion
of same face, fig. 124.)
Flint — light — transparent. Patina — strongly dendritic, especially on convex face — this patina
associated with considerable scaling due to exfoliation. 5.5 X 4.5 X 1.5 cm. Concave face — irregular
radial facets, with portion of cortex in the region of A. Convex face — longitudinally flaked, with some
radial flaking on edge.
The edge about B (dotted in the tracing) consists of flakings which show little patina
and no exfoliation pits. Their aretes are not rounded by sand blasting as are those on
the remainder of the face, but are sharp and fresh. They cut across the patina as if it
had been entirely formed before they were made. We seem to have here the tool of one
age, rejected or lost, picked up much later and refashioned. The edge of the speci-
men is sinuous and beveled, except on the portion near the top in the illustration. Here
there is a facet almost at right angles to the two surfaces, which, with the old nodular
surface remaining near A, may have served as a hand hold.
Fig. 15. Cat. no. 726, P. M. Rabah. (Figure shows convex face.)
Flint — light — transparent. Patina -— yellowish — dull — mottled in spots. 12X5X1 cm.
Concave face — single cleavage plane with the cone of percussion at end A. Convex face — several
radial facets.
The entire edge bears secondary chipping, sometimes on one face and sometimes
on the other, due apparently to use rather than to design. At B is a small notch beveled
from the convex face. At A, a notch has been formed by the removal of a flake at right
angles to the two faces. At C, a notch is beveled from the concave face. At D, there
is a stop-ridge which with notch C affords a good hand hold. Notches A and B do not
seem to be so placed that they could have served for such a purpose.
Fig. 16. Cat. no. 7^, P. M. Rabah. (Figure shows concave face.)
Flint — light — translucent. Patina — concave face, yellow brown — convex face, dark brown,
strongly mottled. Incrustation — calcareous in spots. 8 X 6.5 X 2 cm.
It has a discoidal form apparently due almost entirely to natural agencies. The
convex face is a single large cone of percussion with the point of the impact of the cleaving
force at B. The ripple marks on this seem to indicate that it is an old fracture plane
rather than one due to human workmanship. The concave face has many small pits,
unquestionably due to exfoliation. The main facets appear on close examination to be
due to the same cause. Thus the discoidal shape seems to be the result of natural forces.
The artificial chipping along the edges bears out this conclusion, as it is much less pati-
nated than either face, and lacks entirely the mottled incrustation. This artificial chip-
ping is confined to a retouching of the edges by the removal of small flakes. This occurs
