THE GEOLOGICAL SOCIETY OF LONDON. 

 Vol. II. * 1833—1834. No. 33. 



Nov. 6. — I HE Society assembled this evening for the Session. 



John Ward, Esq. of Holwood, Bromley ; John F. South, Esq , 

 St. Thomas's-street, Southwark ; and Francis Walker, Esq. of 

 Southgate, Middlesex, were elected Fellows of this Society. 



A paper was first read " On a Band of Transition Limestone, and 

 on Granite Veins, appearing in the Greywacke Slate of Westmore- 

 land, near Shap Wells and Wastdale Head," by the Rev. Adam 

 Sedgwick, V.F.G.S., and Woodwardian Professor in the University 

 of Cambridge. 



The author began by stating, that his communication was a short 

 supplement to a former paper, in which he described the range of a 

 band of transition limestone from the south-western extremity of 

 Cumberland through a portion of Lancashire and Westmoreland. 

 He there had stated that this limestone was cut off by the Shap 

 granite, and did not reappear on the north side of it. During the 

 past summer, however, he ascertained, by the help of some new 

 artificial sections laid bare near Shap Wells, that the band of lime- 

 stone does reappear, nearly in its original line of direction; and that 

 it passes, along with the slate rocks, unconformably under the ter- 

 race of old red sandstone and mountain limestone. The phseno- 

 raena are noticed in detail : and a mineral spring is described as 

 rising among these beds, in near connexion with a protruded mass 

 of porphyry. 



The paper then describes some granite veins in the same neigh- 

 bourhood, which rise from the central granite near the farm called 

 Wastdale Head, and penetrate the grauwacke slate. Near the 

 junction of the granite and slate, the latter puts on tlie character of 

 the killas of Cornwall. The change extends to some distance, but 

 gradually disappears, and the slate then returns to its common 

 type, and contains organic remains. The author considers these 

 facts as proving (in this instance) the posterior origin of the granite, 

 and the protrusion of the granite veins into the preexisting slate 

 rocks. 



A. paper was then read entitled " A Notice respecting some 

 Points in the Section of the Coast near St. Leonard's and Hastings," 

 by William Henry Fitton, M.D., V.P.G.S. &c.
