In the neighbourhood of Neufchatel, too, there is an enormous insulated mass of granite, which I am informed, has lately been visited by Mr. Playfair; it is as large as the celebrated foundation of the statue of Peter the Great, erected at Petersburgh, by Catherine II. which is composed of a boulder or detached block of granite, found in a bay of the gulf of Finland, whence it was transported to the Capital; its length was forty two feet, its breadth twenty seven feet, its height twenty one feet In the isle Arran, an immense block of granite is found upon the shore, not only three miles from the nearest granite rock, but having also a bay of the sea intervening; and several similar instances might be adduced, proving the great ravages that have been committed even upon so hard, and unyielding a body as granite.
