SB6 MiNERALOGiCAL OBSERVATION^ 



found the granite. It is here, however, so much 

 covered up, that no junction can be seen. 



9. In a rivulet that descends from the moun- 

 tain, and falls into the Burn of Carnelloch, about 

 a quarter of a mile to the S. E. of the spot first 

 mentioned, we observed a bed of reddish felspar- 

 porphyry in the compact gneiss, at the least twen- 

 ty-five feet thick. I could not certainly deter- 

 mine its dip, the strata around it being so much 

 covered up. All these in the above-mentioned 

 mountain of Millyea, run in the direction N. N. E. 

 highly inclined, or nearly vertical. 



10. In this quarter, we could observe no other 

 junction of the granite with the stratified rocks y 

 but in the Burn of Carnelloch, one mile N. E. of 

 Loch Dee, is a bed of bluish felspar- porphyry in 

 the granite. The direction of this bed, is S. E., 

 and it appears to be nearly perpendicular. It is 

 traceable along the channel of the burn for more 

 than 400 yards, and is in some places 30 feet thick. 

 The boundary of the granite seems to run along 

 the west side of the Millyea, about half w^ay up 

 the hill. 



11. Proceeding onward in a southerly direction 

 towards Loch Dee, we saw no rock but granite, 

 till we came to the Cooran Lane, a considerable 

 stream, which, proceeding from the west, falls into 

 the Dee about half a m.ile after the latter has 

 left its source the Lake of Dee. Into this Cooran 

 Lane,, the before-mentioned Burn of Carnellocli
