GEOLOGICAL SOCIETY. 



Jan. 3. At this Meeting was read " An Account of the Geo- 

 logical Structure of the Bahamas ; by the late Rev. J. Wright, 

 Rector of one of the parishes in Nassau ; transmitted to Pro- 

 fessor Buckland in compliance with the desire of Earl Ba- 

 thurst." From this account it seems that the Bahama Islands 

 are all of similar structure and appearance, composed of cal- 

 careous matter, and barren. Large caves are general, bearing 

 evident marks of having been excavated by the sea. 



Jan. 17. A Paper was read " On the Beds of Limestone and 

 Clay of the Iron-sand of Sussex. By Gideon Mantell, Esq., 

 M.G.S., and Charles Lyell, Esq. M.G.S." Mr. Mantell traces 

 the dii'ection of the calcareous beds connected with the iron- 

 sand formation in the county of Sussex, and enumerates their 

 several localities ; to which he subjoins drawings and descrip- 

 tions of some of the most remarkable fossils found in the lime- 

 stone of Tilgate Forest, pie then adds a letter addressed to 

 him by Mr. Lyell, containing an account of the strata in the 

 neighboui-hood of Horsham, with a section of the quarry of 

 Stammerham, and with remarks on the phaenomena presented 

 by the grooved and furrowed surfaces both of the calcareous 

 and sandstone beds of that country. 



A Notice was then read, accompanied with Specimens, by 

 C. Daubeny, M.D. F.R.S. and M.G.S. Professor of Che- 

 mistry at Oxford, illustrative of the Strata cut through in the 

 Seven Rakes Mine near Matlock, Derbyshire. 



After describing the qualities of the strata of limestone and 

 toadstone, their dimensions, and connexions with each other, 

 and the minerals which they contain, both in veins and regu- 

 larly disseminated through the mass ; Dr. Daubeny concludes 

 with general observations on the phaenomena which they pre- 

 sent. He considers that there would be great difficulty in 

 reconciling the facts there observed, with that theory which 

 refers to an igneous origin the formation of the toadstone. 



On the Vth of February, being the Anniversary of the So- 

 ciety, the following gentlemen were chosen as Officers and 

 Council for the year : 



President.— ^msiTm. Babington, M.D. F.R.S, 



Vice-Presidents. — Arthur Aikin, Esq. F.L.S.— John Bo- 

 stock, M.D. F.R. & L.S. — George Bellas Greenough, Esq, 

 F.R. & L.S.— William Haseldine Pepys, Esq. F.R.S.
