1850 BRITISH ASSOCIA TION A T EDINBURGH 165 



by him into Merionethshire, across Cynicht, Moel 

 Wyn, and Aran Mowddwy, and was continued by 

 Aveline across Montgomeryshire. The plotting and 

 final drawing of his part of the section occupied 

 Ramsay's time in wet weather at Llanberis. The 

 section, engraved by J. W. Lowry, 1 is one of the most 

 striking in the whole series published by the Geolo- 

 gical Survey. The geological structure is portrayed 

 by Ramsay and Selwyn with a boldness and vigour, 

 and at the same time with an artistic feeling, which 

 had hardly been equalled in geological section-drawing. 



The meeting of the British Association at Edin- 

 burgh offered a brief but pleasant break in these 

 labours, as will be gathered from the following jottings. 



' \st August. Murchison in the chair of Section C. 

 Old Jameson 2 was there, and in the chair for a while. 

 He looked just like a baked mummy. I spoke twice. 

 We had some good papers ; Forbes's first-rate, and 

 Mr. Bryce 3 read a good paper as the mouthpiece of 

 the Glasgow Natural History Society. What a rough, 

 strong, clever -looking man Hugh Miller 4 is! My 

 mother was there with Jess, looking very happy and 

 venerable. 



' $rd. This has been a glorious day. Went down 

 to Granton at seven and embarked on board the Pharos 



1 An admirable engraver and accomplished mathematician, who engraved the 

 Sections of the Survey for many years. 



2 Robert Jameson, born 1774, died 1854; the venerable Professor of Natural 

 History in the University of Edinburgh. As mentioned previously (p. 155), he 

 had been a favourite pupil of Werner at Freiberg, and for many years was the 

 acknowledged leader of the Wernerian school in this country. 



3 James Bryce, born 1806, died 1877 ; one of the masters of the Glasgow 

 High School, and author of some geological papers and a little volume on the 

 geology of Arran and Clydesdale. 



4 Hugh Miller, born 1802, died 1856; originally a stonemason in the north 

 of Scotland, devoted his attention to the Old Red Sandstone of that region, and 

 afterwards wrote some excellent popular books on the fishes of that formation, 

 some of which he was the first to discover.
