The Rev. William Liston, Bushbury Vicarage, Wolverhampton ; 

 the Rev. Alfred Deck, A.M., Royal Military College, Sandhurst ;

1. On the Structure of the South-West Highlands of Scotland. 

 By T. F. Jamieson, Esq. 

 (Communicated by Sir E. I. Murchison, V.P.Gr.S. &c.) 

 Contents. 



1. Introduction : general arrangement of the rocks of the district. 



2. The anticlinal axis, and character of the strata composing it. 



3. Succession of the older rocks in Bute. 



4. The geology of Knapdale. 



5. The relations of the rocks of Jura, &c, to those described. 



6. The greenstones of Knapdale ; metamorphic action ; metallic veins. 



7. Probable age of the rocks described. 



§ 1. The following paper is an attempt to throw some light upon 

 the relations of those rocks which figure in our geological maps as 

 the mica-schist, clay-slate, the chlorite-series, and quartz-rock of 

 the South-western Highlands, and the prolongations of which, ran- 

 ging 1ST.E. through the middle of Scotland, form so conspicuous a fea- 

 ture in the geology of that country. 



An examination of these, rocks, as displayed in Bute and Argyle- 

 shire, has led me to believe that from the quartz-rock of Jura to 

 the border of the Old Red Sandstone we have a conformable series
