 which the Meuse, the Moselle, and 

 some other rivers flow, 1 70 ; on rip- 

 ple marks and foottracks in the forest 

 marble near Castle Comb, 317. 



Sedgwick (Prof.), on some beds as- 

 sociated with the magnesian lime- 

 stone, and on some fossil fishes found 

 in them, 2 ; on the geological rela- 

 tions and internal structure of the 

 magnesian limestone ; and the lower

 series in their range through North- 

 amptonshire, Derbyshire, Yorkshire

 structure of the lake mountains of the

 the English coal-fields, 248 ; on the 

 carboniferous chain of the North of 

 England, 249 ; on the carboniferous 

 chain between Penigent and Kirkby 

 Stephen, SIS; on the deposits over- 

 lying the carboniferous series in the

Anniversary Address 1830, 187, — 

 notice of the members deceased 

 during the year 1829, Mr. Holme, 

 188; M. Vauquelin, 188; observa- 

 tions on the drainage of a coun- 

 try, 191 ; on the excavation of val- 

 leys, 191 ; on tertiary formations, 

 1 92 — 1 99; desiderata in English geo- 

 logy, 200 ; on the value of organic 



remains in practical geology, 204 ; 

 on the interruption of continuity in 

 England in the series between the 

 coal measures and the lias, 205; sup- 

 plied on the Continent, 206 ; obser- 

 vations on the error of connecting 

 natural phaenomena with the moral 

 destinies of man, 207 ; remarks on 

 Dr. Ure's new system of geology, 

 208 ; no evidences of returning cy- 

 cles of geological phaenomena, 211 ; 

 geology cannot rise to the rank of 

 an exact science, 212; it is connect-

 and the business of life, 212. 



Anniversary Address 1831, 281, — 

 remarks on metalliferous deposits and 

 veins of segregation, 283 ; on the 

 dislocations which affect the lake 

 mountains and on the mean bearing 

 of the principal mountain chains of 

 Great Britain, 284; on the changes 

 in the carboniferous deposits from 

 the Bristol Channel to the Tweed, 

 286 ; on the deposits of the Isle of 

 Wight above the London clay, 294 ; 

 on the value of organic remains, 295 • 

 on river courses, 296 ; on the original 

 fluidity of the earth, 298 ; on its 

 change of temperature, 298 ; re- 

 marks on Mr. HerschePs paper on 

 the astronomical causes which may in- 

 fluence geological phaanomena, 299; 

 primary modes of material action 

 immutable, 300 ; on volcanic forces, 

 301 ; geological phaenomena are not, 

 like celestial, dependent on a few 

 simple and unchangeable mechani- 

 cal elements, 301 ; remarks on Mr. 

 LyelPs first volume of the Principles 

 of Geology, 302, 311 ; on the degra- 

 dation of continents and the anta- 

 gonist powers, 303 ; existing physical 

 operations not the measure of inten- 

 sity of physical powers at all anterior 

 periods, 301, 304; organic remains 

 provethat the existing order of nature 

 is not the last of an uninterrupted 

 succession of mere physical events 

 derived from laws now in daily opera- 

 tion, 306; proofs of violation of con- 

 tinuity in the series of geological 

 formations, 306 ; on transported 

 blocks, 306; observations on M. Elie 

 de Beaumont's theory of mountain 

 chains, 307; on diluvial gravel, 312; 

 the historic deluge not proved by 

 geological phaenomena, but certain 

 geological phaenomena are capable 

 of accounting for vast inundations, 

 314 ; geology not opposed to moral 

 truth, 314 ; geology lends a great
