or Battle-aM found at Claremont * 153 
1 T ^th inch. Its greatest thickness is 1 ^th inch ; and its weight 
is about 1 lb. 14< oz. 
One of the most remarkable features in this axe, is the per- 
fection of its form, and the smoothness and polish of its surface. 
Upon examining it narrowly, however, the substance of the 
flint seems to have been torn up by the hard powder or stone 
that has been employed in giving it its final shape, and the ar- 
tist has not been able either to remove these imperfections of 
surface, or the short scratches which appear to have been pro- 
duced in the act of polishing. 
As long as antiquaries are at variance respecting the origin 
of the common Celts or battle-axes made of copper and tin, it 
would be needless to offer any conjecture respecting the history 
of the present one. If we suppose, however, what is the most 
probable opinion, that they were offensive weapons used by the 
Britons, Gauls, or Celts ; there can be little doubt that the pre- 
sent magnificent, and, we venture to say, unique specimen, has 
belonged to some of the Chiefs of these ancient people. 
We understand that a polished stone-axe was found in the 
Blue Mountains of Jamaica; and it is well known, that similar 
instruments made of Jade or Axestone, very hard and tough si- 
liceous minerals of a greenish colour, are used by the American 
Indians, and by the inhabitants of the different islands of the 
Pacific Ocean. 
Dr Pearson informs us that there are many stone implements 
of British and Celtic origin in the collection of Sir Joseph Banks, 
but he does not mention whether they are polished, or merely 
chipped into form like those which have been found in Den- 
mark and in the Shetland Islands. 
Such of our readers as may have seen any axes similar to the 
one now described, will oblige us by a communication on the 
subject.
