The elegant form of Nos. 8 and 9 may be noticed.

Flint and Stone Hatchets and Tools. 
No. 2 appears to have been narrowed towards the middle, as if 
to render its attachment to the handle more secure ; this speci- 
men, like many others in the collection, has been used as an 
adze, rather than as a hatchet. 
Many of the specimens in this Case are chisels. Nos. 23 and 
24 are flint picks. No. 28 is an unusually fine polished flint 
hatchet from Ireland, in which country objects of this class, 
made of flint, are rare. 
Flint proper, or chalk-flint, as distinguished from oolitic 
chert, is only found in a very few localities in Ireland, chiefly in 
the counties of Antrim, Down, and Derry; hence we learn 
without surprise that the great bulk of the specimens of that 
material have been procured from the province of Ulster."

Stone Tools and Implements. 
This Case contains a series of stone hammers, tools, and 
implements from Ireland. No. i is a stone for pounding corn. 
Nos. 3 to 18 are difl'erent varieties of hammer-stones, many of 
which show bruising from use. Nos. 17 and 18 were probably 
hafted by twisting a withe around them at the grooved part. 
Some country blacksmiths and platelayers on railways still haft 
their iron hammers in a similar manner. — See No. 34, Case C 42. 
Ancient examples of grooved stone axe-hammers from various 
parts of America are shown in Cases A 41, 42, 46, and 47, and 
No. 9, A 49. 
The hammer-stones Nos. 4 to 1 1 were held between the first 
finger and the thumb, at the places indicated by the depressions. 
Such hammers as 6 and 8 were probably used for flaking flint, 
the blow being delivered from the small end of the stone, as 
is evident from the bruising at that part. — See No. 6. Hammers 
of this form are exhibited from Yorkshire, and from France. 
In Nos. 12 to 16 the depression for holding is deepened into a 
hole ; such hammers, however, were probably still held in the 
hand, unmounted. 
In some hammer-stones more than two depressions exist ; 
thus in the Christy Collection there is a stone-pounder, or 
hammer-stone, from the Andaman Islands, with a series of 
depressi6ns for the fingers and thumb. An ancient hatchet with
