Note B — SKETCH,

The notion of this huge stone being a boulder stone—perhaps from Norway, which was long believed, is now exploded. A friend at Keswick (Sept. 1853) writes me word that the Porphyritic greenstone of which it is composed, runs through many parts of the Lake district, in the immediate neighbourhood, and that this stone must have fallen from the cliff just above. My informant adds, that Mr. Wright, the well known guide, in company with a gentleman, measured the stone and the cavity whence it fell, and found them to correspond; though the cavity is now somewhat overgrown by grass, it is not difficult to perceive.
