The brecciated fragments consist of felstone, felspathic ash, green- 

 stone-porphyry with large crystals of felspar, greenstone, ribboned 

 slate, grey and purple grit, like that of the Longmynd, coarse con- 

 glomerate, and red micaceous stones like pieces of the Old Red Sand- 

 stone. Excepting this last, the assemblage of rocks, and even their 

 distinctive peculiarities (of ribboned slate, felspathic ash, &c. ), are 

 again characteristic of the Longmynd, and of the Lower Silurian 

 series west of the Stiper Stones. The breccia is from twenty-seven 

 to thirty-five miles distant from that country ; and the largest mass 

 observed in it may be about a foot in diameter. 



A remarkable outlier of breccia forms Church Hill, about six miles 

 west of Stagbury, nearly halfway between Stourport and the Titter- 

 stone Clee Hill. It is about three-quarters of a mile in diameter, 

 and rests unconformably on the Coal-measures, serving as a mark to 

 show that the breccia once extended many miles across the country 

 to the west, and that it has been since removed by denudation. 

 The included angular stones are fine altered sandstones, grey and 

 purple grits, red conglomerate (sometimes in masses of 2 and 3 feet 

 in diameter), greenstone and felspathic porphyries, felspathic ash, 

 grey and green slate, variegated and red marls, red felspathic por- 

 phyry, arenaceous limestone, and altered black sandstone. The 

 stones are unusually angular and broken, and the bright-red marly 

 base is larger in quantity than in most of the other localities. Most 

 of the stones possess the accustomed resemblance to the Cambrian 

 rocks and Llandeilo flags with their included igneous masses in 

 Shropshire and Montgomeryshire ; and the limestones, by their fossils, 

 belong undoubtedly to Caradoc of the Montgomeryshire type. 



Pi. few miles further south, this breccia again appears in two 

 places on the Abberley and Woodbury Hills. Both of these patches 

 rest unconformably on Upper Silurian shales and limestones ; and
