Abstract
DURING a visit I made in July last to a respected friend at Dinnington, Northumberland, I observed a travelled boulder in the corner of his field, and, on closer inspection, found that it contained a number of ammonites, encrinites, and the detached portions of the stems of the stone lily, usually found in the Lias in the vicinity of Whitby. The composition of the boulder, which was about two feet in length, and of proportionate breadth and depth, was basaltic or trap, and had evidently taken up the fossils when in a state of fusion; some of the ammonites being compressed or disturbed. Upon inquiry, it appeared that my friend had sunk for a well, and came at the depth of about twelve feet upon the native freestone rock, upon which this boulder was found. Of course it must have been transported to its place of deposit by ice during the glacial period of our world's history, and then covered over by the subsequent boulder-clay; but from whence was it transported? From Yorkshire or the Hebrides?
