from pulling the skin of an animal backwards and forwards ever 
the edge ; this polishing does not extend over the whole sur- 
face of the implements, but only to about three-fourths of an inch 
from the straight edge ; the curved part of the flint was probably 
inserted in a block of wood, and would thus be guarded from 
friction. No. lo shows this polishing very distinctly. 
C 26. 
Upon Tablets i to 3 are other examples of semi-lunar flint 
implements ; of these No. 3 is greatly polished from wear in the 
way previously mentioned. 
In Case C 25, upon Tablet i, are some semi-lunar flint imple- 
ments from Sweden. 
Upon Tablet 4 is the cast of a semi-lunar flint implement. 
Flint Knives and Daggers. 
Dr. Lindenschmit admits the difficulty in separating the 
Scandinavian flint daggers and knives from the flint spear-heads; 
he, however, points out that the thickness of the handles of 
many specimens would render it difficult to bind them to a shaft, 
and that they were probably used, as daggers or knives, in the 
hand. There is also a difficulty in separating the knives from 
the daggers, and, indeed, the distinction, if made, must be very 
arbitrary, depending mainly upon the relative size, with, in the 
case of some of the flint daggers, certain peculiarities in the 
handles. Daggers of flint have been classed as belonging to 
two types: — ist, the broad leaf-shaped; 2nd, those having 
raised ridges at the handle. These last do not appear to have 
been found in Great Britain, although they are not uncommon 
in the North of Germany and Scandinavia. Some flint knives 
have sharp edges at the sides for some distance from the point, 
but towards the butt end, the edges have been removed by 
grinding, apparently with the view of preventing the cutting of 
the string by which they were attached to the handle, or of 
rendering them more comfortable for use in the hand, 
C 26. 
Upon Tablets 5 to 1 1 are flint spear-heads. Upon Tablets 12 
to 16 are flint knives or daggers of the flat leaf-shaped type. 
Nos. 15 and i6 are fine specimens.
