Mr. Horner on the Mineralogy of the Malvern Hills. 293 



3. From Ron a. 



a. Compact epklote of a bright yellowish-green co'Our, forming 

 slender veins which traverse a rock princip illy conposed of flesh-red 

 felspar and a little grey quartz. It is very similar to that from lona, 

 except that this contains less quartz. 



b. A rock composed of hornblende and reddish felspar, together 

 with epidote, both as a constituent part and in veins passing through 

 the rock. 



These two specimens, and particularly the first, are nearly iden- 

 tical with some of the varieties from Malvern. 



c. Compact epidote in small threads passing through vitreous 

 quartz. 



Dr. Wollaston, who had the goodness to compare, at my request, 

 the above specimens from the Western Islands, with those I brought 

 from Malvern, has since found the epidote in similar circumstances, in 

 the Islands of Guernsey and Jersey ; and he has been so kind as 

 give me some of the specimens he collected. They are as follow : 



a. A granular rock, composed of yellowish-green compact 

 epidote and hornblende, in small grains. It is nearly the same as 

 that which I found on the northern face of the End-hill ; the only 

 difference Is, that this specimen from Guernsey contains a greater 

 proportion of epidote. 



b. This so exactly resembles the specimen a from Rona, that 

 they might be considered as portions of the same mass. 



c. Granite consisting of reddish felspar, white quartz and a 

 little greenish-black mica, including a mass of epidote crystallized in 

 slender divergent prisms. This specimen is from Jersey. 



§ 22. On the summit of the ridge w^hich connects the End-hill 

 with the North-hill, there is a rock almost wholly made up of horn-
