PROCEEDINGS OP SOCIETIES. 



GEOLOGICAL SOCIETY OF LONDON. 



Wednesday, Srd November, 1841. — The meetings recom- 

 menced this evening, R. J. Murchison, Esq. President, in 

 the chair. The following communication was read, viz. : 



A supplement to a paper, entitled ' A Synopsis of the 

 English Series of Stratified Rocks inferior to the Old Bed 

 Sandstone,' with additional remarks on the relations of the 

 Carboniferous Series and Old Red Sandstone of the British 

 Isles." By Professor Sedgwick. 



The author commences his paper by stating that his former 

 synopsis is now modified; 1. By the new classification of 

 the stratified rocks of Devon and Cornwall ; 2. By a larger 

 knowledge of fossils, derived from some of the groups 

 described ; and 3. By new observations made during the 

 past summer in the south of Ireland, the south-west of Scot- 

 land, and the north of England.
