her modtts operandi, to explain the unknown by the known. 

 There was another point connected with the subject which the 

 lecturer glanced at, namely, the subject of geological time, 

 which he illustrated by shewing how that all these reefs in the 

 different oolitic rocks had been built by different species of 

 zoophytes, and as the life of individual species was of long 

 durtition, as proved by the zoophytes which construct the reefs 

 in the Gulf of Florida, so then the life of the species in the 

 Jurassic age, if they lived as long then as they do now, 

 justified the inference that the genesis of the oolites was a very 

 old and a very long story indeed. 



Dr. Weight exhibited a beautiful drawing in colour, by his 

 friend Mr. Beach, who had enlarged it from an illustration by 

 Professor Heek, shewing the ancient physical geography of the 

 land with its plants and animals in the Jurassic sea. 



Dr. Weight's paper was followed by one by Professor Dtee 

 on "Clayey Partings in the Cotteswolds." The observations 

 contained in this paper were directed to the composition 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. 



The third Field Meeting for the season was held at 



EADSTOCE, 



on Wednesday, 22nd of July. 



In the year 1872, the Club had visited that portion of the 

 Bristol Coal-field known as the Kingswood and Parkfield Col- 

 lieries, the physical conditions of which were explained, and their 

 relations to the Eadstock basin to the south made clear, by our 

 colleague Mr. Etheeidge, who contributed a valuable paper 

 on the subject to the published Transactions of the Club. It 

 only remained, in order to complete their survey of the entire 

 coal-field, that a visit should be paid by the Club to Eadstock, 

 which place was accordingly made the rendezvous on the day 

 and date above named.
