36 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. 



In addition to the papers already noticed, Nicol contributed me- 

 moirs to this Society upon the Few Red Sandstone of the N.W. of 

 Scotland (Quart. Journ. Geol. Soc. xiv. p. 167.), and upon the 

 ^ Parallel Roads of Glen Roy,'*' which he contended were essentially 

 marine in their origin. 



In literary and scientific labour Nicol was indefatigable. The 

 works we have referred to form but a small fraction of his multifa- 

 rious publications. His Geological Map of Scotland, published n 

 1858, was in every respect the best in its day. In addition to the 

 'Manual of Mineralogy,' he published a smaller work, the ' Elements,' 

 upon the same subject, which is now in its second edition ; and it 

 still forms the article " Mineralogy " in the ' Encyclopsedia Britan- 

 nica,' to which, as to many of the leading Magazines, he was a volu- 

 minous and valued contributor. 



His sturdy frame and indomitable strength of will bore him un- 

 harmed through countless geological journeys that would have over- 

 tasked the majority of men. His genial companionable nature gained 

 him the hearty lovo of his students and the undying affection of his 

 many friends. Ever of singleness and purity of purpose, he dis- 

 dained to swerve from what he felt to be the proper path, either in 

 the interest of authority or expediency ; but for those whom he could 

 aid by his friendship or example, his patience was inexhaustible and 

 his generosity unbounded. 



Sir Walter Calverley Trevelyan, Bart., M.A., E.S.A., E.R.S.E., 



E.G.S., &c., of Nettlecombe, Somerset, and Wallington, Newcastle- 

 on-Tyne, l^orthumberland, was the sixth Baronet of this line*, and 

 born in 1797. He was educated at Harrow, and early displayed a love 

 for Natural-history pursuits, especially Botany, his chosen school- 

 fellow being the late Mr. Eox Talbot (afterwards the chief discoverer 

 of photography). Erom Harrow Sir Walter went to University 

 College, Oxford, where he eagerly attended the lectures of the 

 Botanical and Geological Professors ; and after taking his M.A. 

 degree, he proceeded, in 1820, to Edinburgh to pursue further his 

 scientific studies. 



In 1817 he was elected a Fellow of this Society, and in 1827 he 

 read his first paper : — 



(1) " On a Whin-dyke in Cooper Colliery near Blithe, Northum- 

 berland" (Trans. Geol. Soc. 1829, vol. ii. pp. 405, 406 ; Proc. Geol. 

 Soc. 1834, vol. i. p. 23). 



His subsequent communications to this Society were as follows : — 



(2) "- Indications of recent Elevations in the Islands of Guernsey 

 and Jersey, and on the Coast of Jutland, and on some Tertiary Beds 

 near Porto d'Anzio" (Proc. Geol. Soc. vol. ii. 1838, pp. 577, 578). 



(3) " OnEractured Boulders found at Auchmithie near Arbroath" 

 (Quart. Journ. Geol. Soc. 1845, pp. 147, 148). 



(4) " On Scratched Surfaces of Rock near Mount Parnassus " (Proc. 

 Geol. Soc. 1846, vol. iv. p. 203).
