Analyses of Ancient Alloys.

 be, in some measure, aided by the facts elicited from the foregoing

 ,, 2. A broken sword-blade, from Ireland. 

 „ 3. „ „ also found in Ireland. 



„ 4. A broken spear-head, from Ireland, presenting the only specimen of un- 

 alloyed copper examined. 

 „ 5. A celt, with a socket for the introduction of a wooden handle and an 

 eye, probably for the purpose of attaching a string. 

 Nos. 6 and 7. Celts, composed of a harder alloy, and without sockets. 

 No. 8. A celt, with socket and loop, found in Ireland, and made of a hard alloy. 

 This specimen appears to have been sharpened by grinding.
