associates have ably cooperated, by their united labors and sacrifices, to 
raise this lasting monument, worthy of their own fame and of Imperial 
liberality. As may be seen by the title, Mr. Murchison is the author of 
the first volume, which embraces the structural geol not only of the 
wide extended horizontal steppes of central Russi i, which Mr. 
Murchison has formed the ** Permean” system ; but also the complex hy- 
pogene rocks of the Uralian Mountains, stretching from north to south 
over 16° of latitude, and forming the eastern barrier of Europe. All 
this is drawn out in lucid detail and fully illustrated by excellent geolo- 
gical maps and sections. The pencil of Sir Roderick has also illustra- 
ted his eloquent text, by numerous lithotints of characteristic and pic 
turesque scenes. Within the space of a bibliographical notice no ade- 
quate idea can be given of even the general scope of this noble work. 
But we have in the present number,* given abstracts of some topics, 
and shall, as opportunity offers, continue to cite such passages as may 
be most interesting to our readers. ; 
The second volume, in French, by M. Verneuil and Count Keyser- 
ling, is entirely devoted to a description of the numerous paleozoic fos- 
sils, with the most admirable lithographic drawings of each species. A 
general ‘ coup d’eil’ of the paleozoic fauna of Russia is prefixed to this 
volume, the whole of which must be of the greatest moment and inter- 
est to American geologists, a large portion of whose domain so much 
resembles (in its paleontology) the steppes of Russia—both being mi 
in the peculiar forms of the Silurian era. 
The general interest in these volumes is much increased at the pres- 
ent moment, by the recent arrival in the United States of M. VERNEUIL, 
one of the authors, who will pass the summer in making a rapid recon- 
naissance of our ancient fossiliferous deposits. We feel assured that, 
wherever his researches may take him, he will find those whose famili: 
arity with our fossils will be equaled only by the satisfaction they will 
feel, in making known their results and displaying their collections to a 
distinguished savant, whose familiarity with paleozoic geology is at least — 
as great as that of any living authority. M. Verneuil, as acting presi- 
dent of the Geological Society of France, is virtually the representa- 
tive of European geology ; but we are sure that this official distinction 
is not necessary to secure him those useful and agreeable attentions, _ 
which his affability and manly frankness will so well repay.
