IN THE NORTH-WEST HIGHLANDS OF SCOTLAND. 441 



to the difficult subject with which this paper deals must have 

 listened with genuine pleasure to the story of the solving of these 

 mysteries, which even a few years ago seemed almost to defy the 

 attempts of geologists. Persons who lived before the discovery of 

 " thrust-planes " might well be excused for not having read aright 

 the section at Craig-a-Knockan. It was to be hoped that in the great 

 future which was promised to British geology some attempt would 

 bo made to explain the dynamics of these phenomena. He ventured 

 to point out what seemed to him a discordance between certain 

 sections through the Ben More range and the generalized section 

 through Assynt. 



Mr. Peach explained that the apparent discrepancies alluded to 

 by Mr. Hudleston were due to a difference in the direction of the 

 sections and in the level of the datum-line. He thanked the Society 

 for the way in which the paper had been received, and in reply to Mr. 

 Teall assured him that they had thought about these things, but their 

 solution, he considered, must be left mainly to the microscopist. 



Mr. HoENE alluded to the value of Professor Lapworth's work, of 

 which they had the highest appreciation, seeiug that their conclusions 

 were practically identical. 



Dr. Geikie also expressed his satisfaction at the reception accorded 

 to the paper. Referring to a remark by Dr. Hicks, the survey of 

 the country had not yet got so far as Gairloch, where Dr. Hicks's 

 observations had been made. He was both ready and anxious to do 

 justice to the work of previous writers. Eef erring to the future 

 progress of the Survey, he held out hopes that another paper, 

 giving the results of the detailed study of the southern half of the 

 belt of great complication, might be presented to the Society ere long 

 in anticipation of the Survey Memoirs.
