blende, with a few spangles of mica and a little felspar. Near this, I 

 found granite, which may perhaps be a vein, as the mass is very 

 narrow, and the hornblende rock occurs on both sides of it ; but the 

 turf forms so close a covering, and leaves so very little of the rock 

 exposed, that the relation between the hornblende rock and the 

 granite cannot be determined. 



§ 23. The western side of this ridge is principally composed of 

 a rock of a reddish-brown colour, in which the chief ingredients are 

 quartz and felspar, together with mica and a little epidote : in some 

 of the fissures of it there are minute crystals of quartz and of felspar. 

 On this side of the ridge I also found granite, containing subordinate 

 portions of hornblende ; in some parts of the same mass, the horn- 

 blende becomes the prevailing ingredient, and the mica is wholly 

 w^anting; thus passing into sienite. It is of very small extent, and 

 the micaceous rock just mentioned occurs on both sides of it. 



§ 24. On the summit of the North-hill, a very small portion of 

 the rock is laid bare, and it is so much decomposed, that a gentle 

 blow of the hammer makes it break down into very small fragments. 

 I succeeded however in obtaining a fracture that shewed the compo- 

 sition of the stone, which is a mixture of hornblende and reddish 

 felspar in very small grains, similar to that noticed § 17 as occur- 

 ring on the south-e^ist side of the End-hill, and as prevailing very 

 generally throughout the range. 



§ 25. A considerable part of the north-eastern side of this hill, 

 is composed of granite. This I have already stated to be identical 

 with that on the opposite Side of the valley in the lower part of 

 the End-hill, § 16. This is the only place in the whole range, where 

 I found the arrangement of the rock-ma«ses exhibiting any signs of 

 stratification ; but the indications of it are so very indistinct, that I 

 hardly think the rock can h^ considered as stratified. If it is so,
