Flint Knives. Flint being a very hard substance, which 

 naturally chips to a thin edge, it has from the earliest times been 

 used to form knives. These have assumed various forms, the 

 type mounted on card No. 16, being the most graceful form, 

 and displaying the most artistic finish. The makers of these 

 flints possessed the art of taking off a thin curved chip of flint 

 transversely across the rounded back of the knife-blade.

Oblong Shaped Flints — Knives and various. These specimens 

 show the bulb of percussion on the face, which is flat and 

 unchipped. On the back, or convex surface, they are chipped, 

 some elaborately, others less so. In many of these flints the 

 process of manufacture seems to be only partially completed. 

 Size, if inches to 4 inches long. 



No. 21, Flint Knife, like that represented by fig. 249, Evans's 

 " Stone Implements," but our specimen has not been finished. 

 No. 25, Flint Knife blade, oblong-oval in outline, and quite 

 symmetrical. One surface is flat and unchipped, the opposite 

 side is convex, rounded off to a sharp cutting edge, and most 

 delicately chipped. Length, z\, breadth, f inches. 



B412 to B441, on card 16. 

 Knife-bladed Flints, resembling the preceding — perfect in 

 form, and exquisitely chipped on the convex surface. The 

 margins curve symmetrically to a more or less acute point at 

 each extremity. Fig. 239 of Evans's " Stone Implements" 

 represents, but does not do full justice to this type. Size, if to 

 2| inches, f to 1^ inches broad. 



Arrow-heads. The use of the bow and arrow in war and the 

 chase has prevailed in very ancient times, and still continues 

 amongst many savage tribes, and the use of some kind of stone 

 for points of arrows seems to have been equally wide-spread and 

 enduring. On account of its hardness, some silicious material 

 has always been preferred ; even bottle glass is often made to 

 serve the same purpose. Excellent arrow-points are made of 

 obsidian, but the material always employed by the ancient
