WILLIAM SMITH : HIS MAPS AND MEMOIRS 
Localities will be given in the succeeding part of the work ; and the 
characters of the Genera will be explained. Part II. ivhich completes 
the Work, will he speedily published." This Part II. however, never 
appeared. 
From the " Introduction " we leai'n that " This novel and inter- 
■esting description of near seven hundred species of Fossil Shells, Zoo- 
phites, and other organized Fossils, found in England and Wales, and 
collected in identification of the Strata, refers particularly to the 
specimens of a geological collection deposited in the British Museum. 
On the specimens, Koman capitals mark the genus, — ^the figures 1, 2, 
3, &c, refer to the species. — and the small letters, a, h, c, &c., to the 
localities or sites in the Strata." 
" This copious reference to the stratum which contains the Fossils, 
to the particular site therein whence obtained, and to the individual 
specimens in the collection, which is intended to be publicly exhibited 
in the British Museum, seemed to render figures of them unnecessary ; 
especially as reference is constantly made to another work of the 
Author's now publishing by Mr. Sowerby, which consists chiefly of 
engravings ; and as further reference is also made to the numerous 
figures of Sowerby 's Mineral Conchology." 
The "other work " referred to is " Strata identified by Organized 
Fossils," just described. 
Smith goes on to tell us, in his characteristic way, that " The 
virtuoso will therefore now enter upon the study and selection of Or- 
ganised Fossils with the twofold advantage of amusement and utility. 
The various component parts of the soil, and all the subterraneous 
productions of his estate become interesting objects of research ; the 
contents of quarries, pits, wells, and other excavations, hitherto thought 
unworthy of notice, will be scrupulously examined." And later : — 
"This particular branch of geology has already proved that a large 
portion of the earth once teemed with animation, and that the animals 
and plants thus finely preserved in the solid parts of the earth's interior, 
are so materially different from those now in existence, that they may 
be considered as a new creation, or rather as an undiscovered part of 
an old creation. They are chiefly submarine, and as they vary generally 
from the present inhabitants of the sea, so at separate periods of the 
earth's formation they vary as much from each other ; insomuch that 
each layer of these fossil organised bodies must be considered as a
