A full and elaborate Catalogue oC tlie 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 honourable to himself.— This valuable paper will be 

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

 Pulborouo'h in Sussex, another member of the same profession, has 

 published" a detached Memoir, the developement of a paper read 

 here durin"- the last session* ; which, besides an account of the strati- 

 fication in his own neighbourhood, contains much ingenious specu- 

 lation on the pheenoraena which seem to have attended the elevation 

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

 Hampshire, Surrey, and Kent. 



The accessions to our knowledge respecting the oolitic series, 

 from the Portland strata down to the new red sandstone, have also 

 been considerable during the past year. Mr. Lonsdale, I am happy 

 to say, has presented us with an account of his researches on that 

 important tract in the centre of England, included between the 

 chalk near Calne and the vicinity of Bath; the maps relating to 

 which I had the pleasure of laying before you at the last Anni- 

 versary. This valuable work, one of the most accurate perhaps yet 

 produced in this country, mav be considered as a more advanced 

 stage of the inquiries respecting the oolitic tracts, begun so ably 

 by Mr. Smith, and continued in Mr. Conybeare's Outlines: and it 

 carries on the transverse section of England, from the vicinity of 

 Bristol ; which had already been illustrated by Mr. Conybeare and 

 Dr. Buckland, in their admirable Memoir published in the first part 

 of our Second Series. 



The work upon the Coast of Yorkshire, announced by Mr. Phillips 

 of the York Institution f, will throw light upon a still lower portion 

 of our Oolites, and elucidate especially that remarkable group of 

 strata which includes a series of coal-measures in connection with 

 the lower oolite. It is very much to be desired that all our 

 coasts were thus examined and distinctly represented; such illus- 

 tration being valuable, not only in topographical history, but as 

 affording the best evidence as to the succession of our strata, and 

 tlie greatest facility to the study of them, both by foreigners and 

 our own countrymen. 



The complex and important groups which intervene between t le 

 Oolites and the Transition rocks, have been illustrated during the 

 past year by l^rofessor Sedgwick,— separately in England, and con- 

 jointly with Mr. Murchison, in the Isle of Arran and the north ot 

 Scotland. , , 



Mr. Sedgwick's Memoir on the magnesian limestone, and tne 

 lower part of the new red sandstone, in tlie north of England, is 

 unquestionably one of the most valuable contributions we have 

 hitiierto received ; not only supplying a desideratum of the greatest
