the true Pisolite of Crickley HiU, is the equivalent of part 

 of the Dorsetshire Sands, while the grand Somersetshire 

 section of Ham Hill building-stone, is the equivalent of the 

 Supraliassie Sands of Gloucestershire. 



These views were discussed and commented upon by Dr. 

 Wright and Mr. Ethekidge, both of whom difPered from the 

 learned Professor as to his correlations and deductions. 



A second notice by Professor Buckman bore reference to some 

 curious old green glass bottles, with an heraldic stamp, probably 

 the armorial bearings of the family for which they were made. 



After dinner the Club adjourned to the Tolsey to hear the 



long and able paper by our Colleague and Yice-President, 



Mr. Lucy, on the Gravels of the Severn, Avon, and Evenlode 



Valleys, which forms so important a portion of the published 



" Transactions of the Club " for the present year. A work of 



which it is not too much to say that it will rank with the most 



masterly efforts which have hitherto been made to unravel the 



intricate problem of the successive agencies to which are due 



the accumulations of Erratics, Boulders, Drift, and Gravel 



scattered over the wide area, drained by the rivers above 



mentioned. There is no portion of British Geology more 



difficult of elucidation than the latest changes which have 



taken place in the physical history of Great Britain, dui'ing 



the Pre-Glacial, Glacial, and Post-Glacial periods. Mr. Lucy 



has had many industrious and able predecessors in this field 



of research, of whom it will suffice to name the late Hugh 



Strickland, Dr. Btjckland, Sir Eoderick Mtjrchison, the Eev. 



W. S. Symonds ; Messrs. Hull, Maw, Jones, Witchell, &c. ; 



but it has remained for our friend and colleague Mr. Lucy to 



amass the largest amount of carefully gathered facts over a 



wide area that has ever yet been accumulated; and it is only 



through the accumulation of such facts that truth can be 



arrived at, and sound conclusions drawn respecting the forces 



which have gone to fashion the present configuration of hill 



and valley which we see around us. With a view to the more 



exact understanding of his observed facts, Mr. Lucy has had 



constructed a very elaborate and beautiful Map of the district,
