Tlie President, in the absence of Professor Dyer, read a paper by 

 tliat gentleman on " Clayey Partings in tlae Cotswold Oolites." Tlie 

 observations contained in this paper were directed to the composi- 

 tion of the clay in these fissures, and a comparison was instituted 

 between the chemical constituents of the clay in question and that 

 found under somewhat similar conditions in the Bahama Islands. 



Mr. Moore said this was a physical and not a chemical question. 

 He had been engaged for many years in investigating the nature 

 and contents of these vertical fissures in the Cots wolds, and the 

 results of his inquiries, which had been interrupted by ill-health, 

 had proved of a very remarkable and unexpected character. He 

 found in these fissures evidence of both marine and freshwater 

 action. Of the former, in the presence of portions of a Cirripede 

 (PolUcipes) ; and of the latter in the presence of land and freshwater 

 shells, bog iron-ore, and bones and teeth of Arvicola in great 

 abundance. 



Mr. Etheridge quite concurred with Mr. Moore in the opinion 

 relative to the physical rather than the chemical origin and condi- 

 tion of the clays filling in the joints and fissures. He had with Mr. 

 Lucy carefully examined the condition of the clays in question and 

 the numerous pebbles found in them, and attributed them to the 

 time when the Cotswolds were under water. This was confirmed 

 by the remains of Pollicipes and other forms found by Mr. Moore in 

 the clay of the fissures. 



With the reading of this paper the day's excursion closed. —

1. " On the Gault of Folkestone." By E. G. H. Price, Esq., F.G.S. 

 The author divided the Gault into two great sections, Upper and 



Lower Gault, which he again subdivided into eleven well-defined 

 zones, mostly named after characteristic Ammonites. Each of these 

 zones or beds is numbered, commencing- with No. xi., the zone of 

 Ammonites interruptus, which bed forms the base of the Gault, re- 

 posing upon the Folkestone beds of the Upper Neocomian. 



He found the thickness of the deposit at Copt Point to be 99 feet 

 4 inches. 



He had collected as many as 228 species from the beds, including 

 the following new species : — Avellana pulchella, Natica ohliqua, and 

 Nucula De Bancei, which he described. 



The paper was accompanied by a table of species, setting forth the 

 various beds in M^hich the particular fossils have been met with. 



2. " On the Cretaceous Eocks of Beer Head and the adjacent 

 Cliff-sections ; and on the relative Horizons therein of the War- 

 minster and Blackdown Fossiliferous Deposits." By C. J. A. Meyer, 

 Esq., F.G.S. 



The author remarked that in advancing westward from the Isle 

 of Wight the Cretaceous rocks diminish steadily, although unequally,
