On the excursion of the Geologists Association to Gower last Easter our Director, Mr. R. H. Tiddeman, showed us a series of examples of the celebrated raised beach, and a good deal of discussion arose as to its relation to the other recent deposits of the district. Into those questions I do not propose to enter on this occasion, but will accept, what all admitted, viz., that the beach is an old sea beach, that the platform upon which it rests is the work of the waves, and that it has been raised to its present position by earth-movement.
