 quartz and felspar, united by an argillo-calcareous cement, and the whole crossed by veins of calcareous spar which sometimes cut through the imbedded pebbles. It is very different from the breccia noticed §41. b, as occurring in the lower part of the north side of the Holly-Bush Hill; for in that, the fragments are united by a quartzose base.

§ 45. In the account which I have now laid before the Society of the unstratified rocks of the Malvern Hills, I have chiefly dwelt upon those found in the northern parts. It is there that the rocks are most exposed, and as I resided at Great Malvern, I had an opportunity of examining that end of the range with more leisure and attention than I could bestow on the more distant hills to the south.

Of the Stratified Rocks on the Western Side of the Malvern Hills.

§ 46. In describing these, I shall observe the same plan I have adopted in regard to the unstratified rocks, by beginning at the northern end of the range, and proceeding towards the south.

§ 47. The first stratified rock that is exposed in turning round the End-hill from Great Malvern, is a coarse-grained sandstone of a purplish-brown colour, composed of rounded and angular fragments of quartz and felspar, but chiefly of the former, few of them exceeding the size of a pea. This rock is loosely aggregated, particularly in those parts where the fragments are largest, as the ferro-argillaceous cement is in very small quantity, and even appears to be itself composed of minute grains. It occurs in strata seldom exceeding a foot in thickness, in a vertical position, and bearing N. and S.; a good section of them is exhibited in the side of the road. This sandstone is not however the nearest stratified rock to the Malvern
