With respect to the geological position of the Woolwich beds, 

 Mr. Morris is of opinion that they ought to be assigned to the lower 

 part of the London, as they occupy the same position, with reference 

 to the chalk, as the Bognor strata. 



3. The Bognor or lower arenaceous beds of the London clay are 

 then described, and the following list given of the localities at which 

 they have been noticed: Pegwell Bay (Lsle of Thanet): Heme Bay*, 

 Faversham, Hampstead wellf, Watford, Egham, Bray, Binfieldj, 

 Catsgrove quarry near Reading§, Alum Bay, Bognor^ and Stubbing- 

 ton. At all these localities the strata are considered by Mr. Morris 

 to be contemporaneous and to belong to the lower part of the London 

 clay, reposing in some instances immediatelyon the chalk. Their mine- 

 ral character is remarkably persistent, consisting of greyish green sands 

 with layers of pebbles, but sometimes passing into sandstone and 

 limestone. The fossils, which in some localities are numerous, agree 

 specifically with the well-known Bognor shells j those imbedded in the 

 sands being in good preservation but those in the rock chalky and 

 friable. From the position occupied by these beds Mr. Morris is in- 

 duced to consider them as the equivalents of the lower beds of Wool- 

 wich, Upnor, &c., and in support of this opinion alludes to the strata 

 of calcaire grossier which rest immediately upon chalk at Meudon. 



A Memoir on the Geology of Suffolk, by the Rev. W. B. Clarke, 

 F.G.S., was then commenced. 



February 1. — Jonathan Thompson, Esq., of St. Edmund's Hall, 

 Oxford, and of Temple Grove, East Sheen, Surrey, was elected a Fel- 

 low of this Society.
