published a second edition*, for one of the most convenient and 

 succinct views of the present state of our knowledge respecting them. 



A complete ac6ount of the deposits which appear on the coast of 

 Suffolk, and other parts of the eastern shores of England, especially 

 of that which has been denominated Crag, is still a desideratum 

 of importance in the history of our strata. The publications of Mr. 

 Robberds j- and Mr. R. C. Taylor J have given some information 

 of considerable value upon this tract : but a general account of it, 

 combining the local phsenomena with those of analogous deposits 

 in other quarters, is still to be wished for ; and from the connexion 

 of the facts which our eastern shores exhibit, with some of the 

 great questions touching the true theory of the diluvial accumula- 

 tions, an acquaintance with them is almost necessary to the removal 

 of some of the numerous difficulties which still attend that subject. 



Mr. Webster has announced a new work upon the Isle of Wight; 

 in which, under the simple form of a guide to that most interesting 

 island, he proposes to illustrate fully its Topography and Geology ; 

 particularly the relations of the strata immediately above the chalk. 



The true order of the beds between the chalk and the oolitic 

 series, which has been the subject of much recent inquiry and dis- 

 cussion, appears now to be generally recognized ; and considerable 

 light has been thrown upon that remarkable group, united princi- 

 pally by zoological relations (for, mineralogically, its members are 

 sufficiently distinct), which occurs between the lowest of the beds 

 denominated green-sand, and the oolite of Portland. The suc- 

 cession, though the beds are not continuous, has been shown to be 

 uniform throughout England, from Norfolk southwards, — and to be 

 the same in fact with that long since enounced, though with much 

 variation of nomenclature, by Mr. William Smith, in his Geological 

 Maps of the English Counties. 



A full and elaborate Catalogue of the Fossils of Sussex has been 

 contributed by Mr. Mantell ; whose labours as a Geologist, amidst 

 the duties of an arduous profession, have long been so useful to the 

 public, and so creditable to himself. — This valuable paper will be 

 published in the next portion of our Transactions. Mr. Martin of 

 Pulborough in Sussex, another member of the same profession, has 

 published a detached Memoir, the developement of a Paper read 

 here during the last session § ; which, besides an account of the strati- 

 fication in his own neighbourhood, contains much ingenious specu- 

 lation on the phaenomena which seem to have attended the elevation 

 of the tract beneath the chalk, within the denudation of Sussex, 

 Hampshire, Surrey, "and Kent.
