contact with the granite in the Burn of Palnurej 

 a little way below Graigdews, yet the former evi- 

 dently rested on the granite, and not the granite 

 on it. 



I formerly found the middle granite district of 

 Galloway, to consist of a nearly uniform mass of 

 this rock ; the felspar in general of a greyish- 

 white colour, though in some varieties flesh-red, 

 the mica black or brownish-black, and the quartz 

 of the usual colour. No appearance of stratifica- 

 tion ; the highest m.ountain of the district, Cairns- 

 muir of Fleet, rising to the height of 1737 feet 

 above the sea level, and the whole district ten 

 miles long from north to south, by about four 

 broad from east to west. The strata of the stra- 

 tified rocks in the neighbourhood, I found not to 

 wrap themselves round the granite, or assume the 

 mantle-shape, but to run all in the same general 

 direction, viz. from north-east to south-west, and 

 to dip away from the granite on both the east and 

 the west side. I also, as before noticed, found, 

 that every where that I could obsi^we, except in 

 one place already mentioned, there intervenes be- 

 twixt the transition-rock and the granite, another 

 rock, consisting of felspar, quartz, and mica, in a 

 very compact form, and denominated by Profes- 

 sor Jameson, Compact or Fine-grained Gneiss. 

 This compact or fine-grained gneiss, is in some 

 places observable of a very great thickness. In 

 one place, I saw it at least a mile from the gra-
