BLECHINGTON, (Oxfordshire) 6 m. from Oxford, is the seat of the E. of Anglesey, in whose grounds there is dug a fort of grey marble-stone, of which his Lp. has several chimney-pieces and pavements: and of late, tables, tombstones, and mill- stones have been made of it for the oil-mills; but it is not fit for corn-mills, because in rainy weather it is apt to sweat, like other marbles. There is a good deal of this stone used at the E. of Clarendon's at Coventry, and the pillars of the porticos of St. John's-college at Oxford are built of it.
