72 Bibliographical Notice. 
tail. Geinitz, Quenstedt, and others have given geologists general 
works on fossils; but they fail to be of use to the English geo- 
logist, for several reasons. Prof. Owen’s ‘ Paleontology’ is of too 
special a character. To help those, then, who wish to be acquainted 
with British Fossils and their chief peculiarities in character and 
distribution, Mr. Baily comes forward with a clear and useful guide, 
supplied with the latest information. 
For educational purposes this book is well adapted, being an aid 
both to teacher and student; and for the practical geologist it is 
a desirable vade mecum, reminding him of the typical fossils of every 
stage of strata, whether they are characteristic by peculiarity or by 
relative abundance. 
The work will consist mainly of lithographic plates, accompanied 
by “explanations” and “ descriptive remarks.” In each part, pub- 
lished at short intervals, there will be ten plates of figures; and by 
means of these “it is intended to present to the eye faithful copies 
of the usual and most important fossils found in or characterizing 
the various stratigraphical divisions into which fossiliferous rocks 
are arranged by the geologist, with a view to relieve the mind from 
the necessity of studying the whole series of extinct forms of organic 
life, now known as fossils, and so that the general aspect of each 
particular group may be seen at a glance, conveying, it is presumed, 
with the explanatory remarks, sufficient information for all ordinary 
purposes, and supplying an essential aid in the identification of 
strata.” 3 
We really believe that these plates will contain exact representa- 
tions of both the most remarkable and the most common of fossils 
(many from original specimens), knowing that the author has had a 
long experience as naturalist, draughtsman, and paleontologist ; and 
indeed this first set of the plates, with their explanations, fully illus- 
trate his talent and conscientious care. We must remark, however, 
that some of the plates are “‘ woolly” in appearance, and that the 
printer’s work might be better; nevertheless there are but very few 
real errata. 
The ‘descriptive remarks” in this first Part comprise:—l. A 
succinct note on Paleontological Geology. 2. A table of the Inver- 
tebrate portion of the animal kingdom,—imperfect, however, and 
very loosely put together. 3. A “table of the Fossiliferous or Strati- 
fied Rocks in the order of their superposition” (mainly after that in 
the Geological Survey Museum Catalogue), which is adapted for Eng- 
land and Wales only, except that the ‘“‘Cambrian” of Ireland is 
inserted—that of Scotland and the Laurentian strata of Scotland 
and the Lewis being omitted. 4. Notes on the assemblage of Fossils 
of the Cambrian rocks, giving scant credit to the crustacean Palwo- 
pyge, though in Plate 2 its head is figured as well as its tail. The 
Oldhamiz, however, are here well illustrated, some of their living 
analogues being neatly engraved on wood; and others might have 
been added, if the author had thought enough of filamentous Sea- 
weeds and of the Calciferous Alge or ‘“Corallines” (a name he 
misapplies to the Hydrozoa throughout); nor does he seem to have
