may be considered typical of 

 the order of succession as 

 exhibited generally in the 

 Western Highlands, and 

 that a clear interpretation 

 of it, therefore, must have 

 an important bearing upon 

 many of the other areas ex- 

 amined by them. 



The section (fig. 1) which 

 I propose to describe is, like 

 the others, for the first part 

 along the north shores of 

 Loch Maree and the heights 

 of Kinloch Ewe, but is con- 

 tinued considerably further 

 to the east. Up to a certain 

 point, it will be seen that it 

 agrees very nearly with that 

 given by Sir R. Murchison 

 and Mr. Geikie ; but the 

 subsequent portion is very 

 differently interpreted. 



The gneiss (a) occurs on 

 both sides of the lake, and 

 in its general character it 

 resembles that in the neigh- 

 bourhoods of Gairloch and 

 Torridon. At some places, 

 as immediately to the west 

 of the Loch-Maree Hotel, it 

 is highly quartz ose ; but be- 

 tween this and Gairloch 

 dark grey gneiss and horn- 

 blende schists prevail. At 

 Gairloch, immediately under 

 the Cambrian conglomerate, 

 a pure mica-schist is found. 

 All these varieties may be 

 seen along the roadside, and 

 may be taken as typical, 

 partially at least, of most of 

 the series exhibited on the 

 north shores of Loch Maree, 

 from which our section is 

 taken. 



Resting unconformably on 

 the gneiss, which dips here 

 at a high angle and with 

 a N".W. strike, are the con- 

 glomerates and sandstones
