VI. ExtraSi of a Vetter of' the Reverend Mr. W illiam Rice,, 
p/ Caerleon upn Usk, to Charles Williams Efqy 
giving an account of an ancient Roman Infcription late* 
ly found there. With fome Conjectures thereon^ hy the 
Reverend Dr. John Harris, S. T, P. and R, S. S. 
Sir, 
A Perfon laft Week being at Plow in a Clofe near 
the Bank of the River Usk, which the Ancients 
called Jfca, (which glides by us about a quarter of a 
Mile off, and in fight of this Town^ came thwart a 
Stone, and finding Letters thereon, took it up whole ; 
*tis about a Yard in length, and about three Quar- 
ters broad I went to the place, and took a true 
Copy thereof, which 1 here make bold to fend you. ^ 
There was underneath it fome feeming Oblong Square 
Sepulcher of Stones, rude in order. A little further 
in that Glofe, where that River wears out the Land, 
there was, fome time before, a large Earthen Pot taken 
out of the Bank by the River- fide, which had therein 
the Scull and Bones of fome Perfon, by fome thought 
to ber%kCbild , Murther’d j But I rather conjecture it a 4 
Roman iJrn.
