The success I met with in discovering the Druidical monuments in Derbyshire (which I had the honour to lay before the Society), induced me to make an excursion into Yorkshire, to examine some curious groups of rocks, seven miles from Ripley, on the road to Pateley Bridge, called Brimham rocks. They are indeed a most wonderful assemblage, scattered about the moor in groupes, which all together occupy a space of above forty acres. The extraordinary position of these rocks in a variety of directions must have been occasioned by some violent convulsion of nature; but at the same time it is evident, that art has not been wanting to make their situations still more wonderful.
