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 
Surrey, Kent, Sussex, and the contiguous counties ; as obtained by well-sinkings 
and other sources. 
Geological Topoorapht. — " Sir, — Would it be worth the trouble to publish 
a list of the towns of England, with their strata ? — I send a specimen of what I 
mean, as you will understand it better from that. — Yours, &c. G. H. West, 
Blackheath."

We thulk in a modified form such a li.st might prove very useful, especially 
one of the chief towns with their prominent geological features, of those noted 
for the occurrence of particidar fossils, and of those where good sections of 
])articular rocks are to be seen. If our readers and con'espondents will supply 
the information, we will revise, aiTange, 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 drift to contain sheUs of such fragile forms as those which I have inclosed 
for your inspection ; and also whether these are freshwater or marine ? 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 diift, 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 manimahan 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
