PROCEEDINGS OP THE GEOLOGICAL SOCIETY. [Feb. 26, 



of the hill at the south-eastern end of the lake. Near its outlet into 

 Glen Spean, Loch Treig tapers to a narrow point, owing to the near 

 Fig. 1. — Outline-map of apart of Inverness-shire, showing the Glacial 

 Strice and the distribution of Moraine-matter on the Spean and 



3re. 



N.B. — The syenitic area, finely dotted in the map, is mainly after Macculloch. 

 The boundary of the syenite on the south side of the Spean is unknown 

 to me, and even that on the north side is in some parts conjectural. There 

 is much granite in the hill to the N.E. of Craig Dhu ; but it is of a different 

 character from the other. — T. F. J.
