range is Banked throughout on the western side by the old red sandstone, and 

 apparently by the same formation on the north-eastern side also, in the space 

 that intervenes between Much Marcle and Ledbury ; while on the north the 

 old red sandstone likewise appears, surrounding the isolated transition hill of 

 Shucknell. But in the eastern quarter, between the north-eastern foot of May 

 hill and Newent, a small coal-field reposes on the transition tract. On the 

 other hand, to the east of Ledbury we encounter a second range of the tran- 

 sition series, bearing the name of the Doghill chain, whose general course is 

 also toward the north, and which is supported on the east by the chain of 

 Malvern. 



On the south and east of the limits now described, the new red sandstone 

 formation universally prevails, commencing on the right bank of the Severn, 

 near Newnham, and consisting of beds of red friable sandstone and clay-marl ; 

 this supports lias limestone on its eastern confines, and is thence expanded 

 into the interior of the island. 



§ 32. Of the Malvern range, and the district adjacent to it, the valuable 

 description given by Mr. Horner in the first volume of the Geological Trans- 

 actions, may seem to render further observation superfluous. Hence I con- 

 fine myself to the remark, that the chain of Malvern — being found to consist of 

 syenitic granite, syenite, greenstone, and hornblende, with some indications 

 of gneiss and mica-slate, in which no organic remains have been observed, 

 might be held to be of primary origin ; if on the other hand the occasional 

 appearance in those rocks of calcareous spar, brown-spar, and sulphate of 

 barytes, both traversing them in the form of small veins and strings, and occur- 

 ring also disseminated, did not seem to indicate an affinity between this chain 

 and the transition series ; — since the latter, by which the chain is bounded on 

 the west, likewise contain slight veins and filaments, and interspersed portions, 

 of the same substances. (See Geol. Trans, vol. i. p. 281) — 311.) 



In the Doghill range, immediately to the east of Ledbury, and in the inter- 

 rupted ridges situate more eastward, the transition beds are disposed in repeated 

 undulations from east to west ; the ridges themselves affecting a northerly 

 and southerly extension, nearly parallel to the range of Malvern. But portions 

 of these ridges being also occasionally raised into protuberant knolls and 

 swells, the beds are found in some places dipping to all points of the com- 

 pass, either continuously, or partially abrupted. 



§ 33. 1 have not had an opportunity of fully developing the stratified struc- 

 ture of May hill, and its southern extension to Huntley hill and Nott's hill: 

 It is, however, quite analogous to that of the other portions of the transition
