1867.] TIMTNS MALYEEN HILLS. 36o 



LXII. Trap near the summit of the West Peak of the Ragged 

 Stone, dark bluish-grey uncrystallized epidote in the interstices. 

 G=2-862. 



LXIII. Trap from the same place, higher up, consisting of horn- 

 blende imperfectly crystallized, and some brown felspar of no distinct 

 cleavage. 



LXiy. Trap from a small dyke near the south end of Midsummer 

 Hill, greyish black, cryptocrystalline, contains pyril;es. G= 2-9368. 



LXY. Trap from a large dyke. Midsummer Hill. A confused 

 mixture of hornblende and a reddish felspar indistinctly crystallized. 

 G = 2-834. 



LXVI. Trap from a dyke crossing Swinyard Hill, greenish black, 

 imperfectly crystallized; hornblende, felspar, and pyrites. G = 

 2-979-3-198. 



LXYII. Trap from a dyke north of the Cave, Herefordshire 

 Beacon, from the east slope of the ridge, thirty or forty yards down 

 into the ravine dividing the eastern buttresses of the Beacon from 

 east to west. Hornblende ; felspar partly of a waxy and partly of 

 a vitreous lustre, allied to Labradorite; traces of epidote and 

 hematite. G= 2-855. 



LXYIII. From a mass of trap immediately south of the cave, on 

 the west side of the ridge. The fragment analyzed was taken from 

 the part of it which is in the wood ; it contains hornblende, labra- 

 dorite, glassy felspar, and garnet. Some parts of this mass of trap 

 contain, in addition to the above, hypersthene, some free quartz and 

 massive felspar, which, when freed from the protoxide of iron by 

 which it is stained, is greyish white. G=2-952. The specific 

 gravity of a portion taken higher up, near the footpath, =2-912. 



LXIX. Prom trap immediately below the cave, to the west of it ; 

 the specimen is from the narrow footpath passing under it. Soft, 

 greenish black, no distinct crystallization, contains a little haematite. 



LXX. Prom the east slope of the buttresses of the Herefordshire 

 Beacon, south of the deep ravine which divides the buttresses from 

 east to west, and overlooking a farmhouse at the extreme end of 

 Castle Morton Common. Hornblende, and brown and red felspar of 

 no distinct cleavage. 



LXXL Prom the same place. Both these specimens were taken 

 from a large irregular mass of crystalline rock, which in parts con- 

 tains epidote, massive and crystallized. The intrusive character of 

 the entire mass is doubtful. Some parts of the rock resemble the 

 "diorites" of the North HiU. It is possible that other substances 

 may have become included in the eruptive rock, and metamorphosed 

 with it. This specimen contains hornblende, labradorite, a little 

 glassy felspar, epidote, and haematite. G = 2-827-2-931, increased 

 by the local addition of epidote to 3-043-3-058, and in one spot to 

 3-292. 



LXXII. Greenish-black trap from a linear dyke on the east side 

 of a hill, near a tree, and north of the ravine above mentioned. 

 G=2-849-2-864. 



LXXIII. Greyish-black trap, containing small crystals of horn-
