 paper was illustrated by some admirable diagrams, and by si)ecimens from the 

 cabinets of Dr. Bowerbank, N. T. Wetherell, Esq., and the author. 



NOTES AND QUERIES. 



Thickness of Chalk-strata around the Wealden Area. — The Editor 

 will be obliged by notes on the local thickness of the Chalk and Lower Greensand in 

 SuiTey, Kent, Sussex, and the contiguous counties ; as obtained by well-shikings 

 and other somces. 



Geological Topography. — " Sir, — Would it be worth the trouble to publish 

 a list of the to^vns of England, with their strata I send a specimen of what I 

 mean, as you will understand it better from that. — Tom's, &c. G. H. West, 

 Blackheath."

We think in a modified form such a list miglit prove very useful, especially 

 one of the chief towns with their prominent geological features, of those noted 

 for the occurrence of particular fossils, and of those where good sections of 

 particular rocks are to })e seen. If our readers and correspondents will supply 

 the information, we will revise, arrange, and print the matter thus accumu- 

 lated. — Ed. Geol. 



Shells in Pleistocene Deposit at Cambridge.—" Sir, — Would you in- 

 form me, through the medium of your valuable ' Notes and Queries,' if it be usual 

 for the dj-ift to contain shells of such fragile forais as those which I have inclosed 

 for your inspection ; and also whether these are freshwater or marine 1 Also, could 

 you tell me of any work of moderate price devoted exclusively to the drift forma- 

 tion ? The shells forwarded were found in the drift, about 10 or 12 feet below the 

 surface, in a thin layer of fine sand about 4 inches thick, resting upon a sort ef 

 clayey sand about 18 inches thick, which last also contained shells, but not in such 

 abundance as the other. — Yours, &c. A Beginner, Cambridge." — The deposit in 

 which the shells forwarded were found, we should consider to be a Pleistocene 

 freshwater deposit, and not drift. The species we recognise are : — 



Land and freshwater shells are by no means unusually found in such deposits, 

 which should be searched also for mammahan remains, the newer forms of which 

 may occur, though not the hippopotamus and older species. 



Cement for Chalk Fossils. — " Dear Sir, — Can you kindly give me the 

 receipt for making the ' diamond cement ' used in repairing chalk fossils ? — Yours
