the road which winds round the End-Hill. The rock fouiid in this 

 place is of a dark green colour, of a loose texture, and is cctaposed 

 principally of steatite, with a little felspar and quartz. It is traversed 

 by a slender vein of granite, but as there is a very inconsiderable mass 

 of the rock exposed, I had not an opportunity of tracing the vein 

 but for a very short way. 



^ § 16. A great part of the End-Hill is composed of granite, parti- 

 cularly on the west side, where it contains veins of quartz in several 

 places. It occurs near the bottom of the hill on the south-east side, 

 and is also found in. very large masses on the opposite side of the 

 valley which separates the End-Hill from the North-Hill. In this 

 valley I found a loose black, composed of white felspar, grey quartz, 

 and greenish-black mica, with a little hornblende. In one part of the 

 specimen that 1 detached from the mass, these materials become more 

 minute, and assume somewhat of a slaty structure. Where this is 

 the case, the mica is more abundant. 



§ 17. In the same part of the End-hill, but at a higher elevation 

 than the granite, there is a rock which prevails very much throughout 

 the whole range. It is of a purplish-brown colour, with a fine close- 

 grained texture and an uneven fracture. It is composed of horn- 

 blende, felspar, and a little quartz ; sometimes contains a small 

 quantity of magnetic pyrites, and slender veins of compact epidote ; 

 in the fissures of it, crystallized sulphate of barytes and minute rhom- 

 boidal crystals of ferriferous carbonate of lime are also occasionally 

 met with : this rock would probably be arranged with the greenstones 

 in the classification of Werner. On the west side of the End-hill, 

 and in some part of the eastern side, a rock is met with, the charac- 

 ters of which correspond very nearly with those of sienite ; it is 

 composed of hornblende and felspar, with a few spangles of mica. 

 . § 18. On the northern side of the End-hill, a rock occurs
