254 acute angle with the other." The angle made by this edge with the major axis of the flake is 38° in two specimens, and 31° in a third. In the second (fig. 10) both ends have been slanted off, and the

curved edge of the flake has been worn, while the straight one is sharp. The unworn edge has probably been inserted into a handle of some sort or another. Three of the first kind were met with, and one of the second.

A drill, or piercer, is represented in fig. 11, formed out of a small flint flake. It is of similar shape to those figured from the caves of Périgord in the 'Reliquiæ Aquitanicæ.' The manufacture of implements is proved to have gone on in the cave by the presence of large numbers of flakes and a few chipping- blocks.

The general facies of the whole collection of implements, and their association with the extinct mammalia in the cave-earth and breccia, prove them to be of Palæolithic age.
