Specimens to illustrate the brecciated conglomerates of the 

 Permian or lower Red sandstone series that occur at the 

 south end of the Malvern Hills at Howler's Heath, at in Itecess 41 

 Knightsford Bridge, on parts of the Abberley Hills, near 

 Enville, on the Clent and Lichey Hills, fyc. 



On the Abberley Hills at Woodbury, and behind Hun- 

 dred House, at Stagbury Hill, Warshil], and near Enville, 

 the same brecciated conglomerate forms part of the Permian 

 strata, in a long interrupted line. Also at Church Hill, six 

 miles north-west of Hundred House, there is an outlier of 

 breccia lying on coal-measures. It also occurs in beds 400 

 feet thick on the Clent and Bromsgrove Lickey Hills, at 

 Frankley beeches, and at Northfield, on the east side of the 

 south end of the South Staffordshire coal field. The frag- 

 ments that form this remarkable rock are all angular and 

 subangular. Some of them are from two to three feet in 

 diameter, and deserve the name of boulders. Many of them 

 are polished, and some are well scratched and striated. They 

 are invariably embedded in a red marly clay, and in all 

 cases they do not consist of fragments of the neighbouring 

 rocks, but chiefly agree in lithological character with the 

 Cambrian rocks of the Longmynd in Shropshire, the Llan- 

 deilo and Lingula slates and altered rocks, and the traps 

 and ashes of the same distant area, together with certain 

 Pentamerus or upper Llandovery limestones and conglo- 

 merates which contain peculiar green pebbles of Longmynd 

 rocks, and lie unconformably on the Longmynd Cambrian 

 rocks and the Llandeilo flags, between the Stiper Stones and 

 Chirbury. The pebbles and blocks therefore of the breccia 

 chiefly consist of felstone porphyry, greenstone porphyry, 

 greenstone amygdaloid, altered ribboned slate, black and 

 green slate, felspathic ash, quartz rock, quartz conglomerate, 

 purple and green Cambrian slate and coarse conglomerate, 

 grey grit, and sandy Pentamerus limestone. This limestone 

 often occurs in the Breccia (as at Northfield) in large angular 

 slabs, full of the peculiar assemblage of fossils that mark that
