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



" felspar.*" From this description, the epidote may be considered as 

 forming a constituent part of the mass, and it accords witli some of 

 the varieties I found on the Malvern-hills. But as the rock which 

 Saussure met with was in detached pieces, we cannot determine 

 whether they were not portions of a vein. 



§ 21. Since my attention has been directed to the subject, I have 

 ascertained that epidote occurs in Cumberland, and in the Islands of 

 lona and Rona, two of the Hebrides, in a state similar to some of 

 the varieties I found on the Malvern-hills. In examining some 

 specimens from those places in the collection of Mr. Greenough, I 

 found the following. 



1. From Cumberland. 



a. Crystallized epidote shooting through quartz, from Wallow 

 Crag near Keswick, very similar to what is found in the valley of 

 Chamouni. It is more distinctly crystallized than any I saw at 

 Malvern. The specimens are evidently portions of a vein. 



b. Epidote in a compact state, mixed with reddish felspar, form- 

 ing a vein in a schistose rock from the same place. 



2. From lona. 



Compact epidote disseminated in small veins, through a rock con- 

 sisting of red felspar and quartz.
