On forming Collections of Geological Specimens. 271 
Also, in consequence of some pecuniary assistance from Go- 
vernment, Mr. William Smith has begun to lay the result of his 
researches before the public*. This assistance has been given 
Mr. 8S. on condition that he arranged and placed his collection | 
of fossil shells, &c. in the British Museum, for the use of the 
public. He has already published several numbers of his “ Strata 
identified by organized Fossils,” containing engravings of the 
most characteristic shells of each stratum; and also the first part 
of his ‘* Stratigraphical System of Organized Fossils +,” refer- 
ring to the specimens in the British Museum. 
The latter work describes the principal shells found by him in 
the British series, from the uppermost down to the lias strata = 
and with this communication you will receive an alphabetical 
list of the places where these shells were found, with the num- 
ber of species from each place. The object of this list isto direct 
the attention of collectors to the places from whence specimens 
are most likely to be obtained; both to enable them to repeat 
the observations of preceding inquirers, and to extend their ob- 
servations to other places f. y X and Z, 
An Alphabetical List of the 263 Places which supplied Mr. W. 
Smith with the 1155 Specimens of Fossil Shells above the 
Lias Strata, that are deposited in the British Museum, and 
described in the first part of his ‘* Stratigraphical System.”

* It is to be regretted that Mr. S. had not encouragement sifficient to 
induce him to publish those works sooner, as we understand he has long 
been in possession of the materials; indeed they form the basis of his 
great work “ The Map of the Strata of England and Wales ;” and there- 
fore he must have been far adyanced in those mquiries when he began that 
arduous undertaking. 
+ We shall be better pleased with this work when it is furnished with 
copious index to both the shells and places, with the bearing and di- 
stance of each place from some principal town or village. Also a simple 
outline engraving of each shell would be very desirable. These additions 
would add much to the real value of the work, without materially increas- 
ing the expense,—an expense which might perhaps have been lessened in 
some other respects,
