degradation, tlie gypsiferous marls being denuded throughout the 

 greater part of the centre of the basin, and but rarely exhibiting 

 caps of the compact paludina-limestone. On the southern, 

 eastern and south-western flanks of the basin, particularly near 

 Gaudix, there are vast accumulations of pebble beds, conglomerate, 

 &c., the exact r^ations of which to the marls and limestone the 

 author could not satisfactorily determine, owing to the obscurity of 

 the sections ; although he is of opinion that there are conglomerates 

 which in some places pass under the marls, whilst in others they 

 are decidedly overlying. 



The reading of the letter on the Basin of Alhama was deferred 

 until another evening.

The reading of a paper on the Geology of Weymouth, and the 

 adjacent parts of the coast of Dorsetshire, by the Rev. Dr. Buck- 

 land, and Henry Thomas De la Beche, Esq., begun at the last 

 Meeting, was concluded. 



The Authors take up the history of the Geology of the Coast of 

 Dorset at the point where Mr. Webster terminates, viz. at the 

 chalky promontory of White Nore, about eight miles E.N.E. of 

 Weymouth, and continue their account of the coast thence 

 westwards to the lias at Charmouth. The Memoir is accom- 

 panied by a map and many sections both of the cliff's and of the 

 adjacent inland district, including the space intermediate between 

 the escarpment of the chalk downs of Dorsetshire and the sea. The 

 authors divide this district into two compartments, viz. the Vale of 

 Weymouth and the Vale of Bredy. 



The structure of the Vale of Bredy is comparatively simple, being 

 chiefly composed of chalk, greensand, Kimmeridge clay, Oxford 

 oolite, forest marble, and inferior oolite, dipping for the most part 

 to the E. and N.E. and divided by thick beds of clay. 



The Valley of Weymouth is more complicated, comprehending 

 tertiary strata, chalk, greensand, Purbeck and Portland beds, Kim- 

 meridge
