288 Mr. Horner on the Mineralogy cf the Malvern Hills. 



§ 12. The stratified rocks which occupy the country to the west- 

 ward, rise in some places to a considerable height on the side of the 

 range ; the highest poin: where I found theai, was en the Hereford- 

 shire beacon, at about one third of the elevation of that hill. The 

 particular arrangement of these stratihed rocks I shall relate in a sab- 

 sequent part of this paper. 



§ 13. I have deposited in the collection 'of the Society, a series of 

 specimens illustrative of the mineralogy of the district I am now 

 describing. Among these, there are several which may at first sight 

 appear to be duplicates, but they all possess iha.'es of difference ; and 

 in a collection of the mineral productions of any particular district, it 

 is material that every variety should be contained, for by these grada- 

 tions the connection between rocks of very dissimilar appearances is 

 frequently made out. The specimens of the unstratified rocks are 

 chiefly from the northern part of the range where the rock is most 

 exposed. 



Of the tinstrat'ijied Roclis. 



§ 14. Although some of the rocks I shall describe under this head 

 have a slaty structure, and as such, were probably formed by succes- 

 sive deposition ; yet as they are of comparatively rare occurrence, and 

 when found, are only in irregular masses without any continued stra- 

 tification, I shall employ this term to distinguish the rocks that com- 

 pose the central part of the range, from the stratified rocks, which, as 

 I have already said, occasionally rise to a considerable height upon the 

 western side of it. 



§ 15. The most northern point where the unstratified rocks are 

 seen above the surface, is about a quarter of a mile in a direct line from
