Introduction. — The first notice of the district described in the 

 present paper was that published in 1800 by the late Professor 

 Jameson in his * Mineralogy of the Scottish Isles.' It is exceedingly 

 meagre, having been compiled from the notes of a brief excursion in 

 bad weather, and contains only a list of minerals found in the ascent 

 of Beinn na Cailleaich, with the mention of numerous basalt-veins 



* See vol. xiii. pp. 360 et seq. 



f The Sections figured on this Plate have been selected from the series of 

 sketches communicated by the author as illustrative of the Geology of Strath, 

 and now in the Society's Library. The un figured Sections will be referred to in 

 the paper.
