TIMINS— MALVEEN HILLS. 



357 



XXIII. Fine-grained greyish rock, of the structure of sandstoue 

 with occasional thin lines of epidote, from a band in the HoUybush 

 Sandstone, on the east side of the eruptive rock, quarried on the 

 south-west side of Midsummer Hill : passing into felspar. 



XXIV. Felspathic portion of the same rock. 



XXY. Lava-bed, west of Castle Morton Common. Matrix of a 

 bluish colour ; cavities filled with epidote. G=2-617. This rock, in 

 its external characters, resembles the amygdaloidal greenstone of 

 Caer Caradoc, and that from the top of Lawley, Stafi'ordshire, 



XXYI. Greyish sandstone. From the hill overlooking Little Mal- 

 vern. 



III. Shales. 



Shales and schists do not properly belong to the subject of this 

 paper ; but some of them approximate so nearly in composition to 

 the beds of volcanic ash with which they are associated that it is 

 necessary to notice them. I therefore give here the result of the 

 analysis of the different kinds of shale found in the south and south- 

 west part of the chain.

XXYII. YeUow shale, east of Coal HiU. 



XXYIII. From the upper part of the bed of shale numbered 3 

 in Dr. Holl's section across the northern extremity of Coal HiU, loc. 

 cit. p. 89. 



XXIX. From the lower part of the same bed. 



XXX. Blue shale immediately above the lava boss, Y. YI. YIL, 

 south of the Eastnor Road, interstratified with black shales. The 

 divisional surfaces in the plane of the bedding are stained by hy- 

 drated peroxide of iron. 



XXXI. Black shale from the field near Fowlett's Farm. G=2-455. 



XXXII. Part of the same beds, in contact with lava, YIIL, by 

 which it has become bleached. G= 2-448. 



XXXIII. Smooth metamorphic schist, in thin beds, with steatitic 

 surface, interposed with rock at the north side of the quarry to the 

 south of the West Ragged Stone.
