many belong to the Stone period ; most of them appear to have 
been drilled with a metal tool having a hollow base, which 
would cut out a core, and not involve the extra labour of grinding 
away the entire substance of the stone. Nos. 7, 11, 13, 14, 18, 
and 21 in this Case, from Ireland, have probably been drilled 
in this manner, as well as No. 18, Case A 30, from France; 
Nos. 12, 15, and others, in Case A 39, from Denmark : most of 
the drilling in the American series. Cases A 50 and A 51, and 
in the large series of stone smoking-pipes from the mounds of 
Ohio, Cases C 34 to C 39, was effected, probably, with tools of 
bronze. 
Nos. 46, 47, and 48 are flint arrow-heads from Scotland.

Wales. 
No 37 is the cast of a sculptured drilled stone hammer; the 
original, which is unique, was presented to the Society of Anti- 
quaries of Scotland by the Rev. E. L. Barnwell. It was found 
about 1 840, in stubbing up a wood at Maysmote, near Corwen, 
Merioneth. 
Stone and Flint Hatchets and Implements from France 
ARE EXHIBITED IN CaSES A 28 TO A 30, AND D 15 TO 18. 
A 28. 
Nos. 2 and 20 are short flint hatchets, probably intended to 
be mounted in handles of stag's horn, or other material, in a 
similar way to the specimens from the Swiss lake-dwellings in 
Case A 31, and upon the top of Case H 8. Nos. 8 and 9 are 
nicely chipped flint implements ; No. 9 appears to have been 
intended for a gouge. 
A 29. 
Some very fine examples of flint hatchets are shown in this 
Case, such as Nos. 2 to 6 ; No. 2 exhibits a number of planes, 
caused by its having been rubbed on a flat surface. 
No. 14 is an unusual form of hatchet from France; it is almost 
Danish in type. 
A 30. 
The specimens in this Case are chiefly of greenstone, and 
are highly finished. No. 5 is a most elegant form of hatchet. 
Nos. 20 to 27 are classed as chisels. No. 28 is a portion of a 
hammer-stone. No. 9 is highly polished at both ends, but the 
intermediate part, around which the fastening to the handle was
