PKOCEEDINGS OF THE GEOLOGICAL SOCIETY. 



with sheets of sections of the highest interest and value ; and to make 

 the work more complete, the results of a series of soundings care- 

 fully taken on most of the lakes by this indefatigable worker are 

 also given. 



In the years 1875 and 1876, and more recently, microscopical 

 examination of the rocks of the Lake District occupied much of 

 his time. Of papers on this subject I may here note one " On 

 the Granitic, Granitoid, and Associated Metamorphic Rocks of 

 the Lake District," the first part of which appeared in the Quart. 

 Journ. Geol. Soc. for 1875, and the second in the volume of the 

 same periodical for 1876. Another paper is entitled, " Notes on 

 the Comparative Microscopic Eock-Structure of some Ancient and 

 Modern Volcanic Eocks," and appeared in the Quart. Journ. Geol. 

 Soc. for 1875. Among his latest contributions to geological litera- 

 ture may be mentioned " Notes on the Geology of the Isle of Man," 

 which appeared in the Geological Magazine for January, 1880. The 

 following is by no means an exhaustive list of his productions : — 



1. In 1868, "Internal Fluidity of the Earth." Geol. Mag. v. 

 pp. 581, 582. 



2. In 1869, " Suggestions as to Geological Time." Geol. Mag. 

 vi. pp. 8-13. 



3. In 1869, " On Beds of supposed Eothliegende Age near 

 Knaresborough." Quart. Journ. Geol. Soc. xxv. pp. 291-297. 



4. In 1870, " On the Denudation of the Lake District." Geol. 

 Mag. vii. pp. 14-17. 



5. In 1871, "The Development of Land." Geol. Mag. viii. 

 pp. 11-15. 



6. In 1872, " On Sock-staining." Geol. Mag. ix. pp. 389-391. 



7. In 1873, " On the Scenery of the English Lake District, 

 geologically considered." Brighton, Proc. Nat. Hist. Soc. xx. 

 pp. 39-44. 



8. In 1873, "On Eock-fissuring." Geol. Mag. x. pp. 245-248. 



9. In 1873, "The Glaciation of the Northern Part of the Lake 

 District." Quart. Journ. Geol. Soc. xxix. pp. 422-441. 



10. In 1870, " Coral Eeefs and the Glacial Period." Quart. 

 Journ. Sci. iii. pp. 170-178. 



But the most characteristic side of his untiring energy, and 

 perhaps its most important one, was the zeal with which he worked 

 for the diffusion of scientific knowledge while in Cumberland. 

 Before leaving Yorkshire he had written a small elementary book 

 on Physics ; and one of the firstfruits of his educational activity 

 at Keswick was a similar work on Geology, composed of nine 

 lectures delivered in the first place before a school audience, and 

 secondly before the Keswick Literary Society. Being simple, 

 clear, and free from unnecessary technicalities, his lectures soon 

 became popular, and the lecturer himself acquired influence. 



As the originator and main support of the Cumberland As- 

 sociation for the Advancement of Literature and Science, and 

 of most of the local societies connected with it, he accomplished a 

 work which it may be hoped will not now be suffered to languish,
