THE GEOLOGIST. 
Phaneropleurine, and Coelacantli Crossopterygidse, and lie leaves tlie 
bearing of these unquestionable facts upon the great problems of zoo- 
logical theory to be developed by every one for himself. The craniofacial 
bones which Professor Huxley recognizes in the Devonian fishes are the 
Supraoccipital, Frontal, Ethmoid, Epiotic, Parietal, Squamosal, Post- 
frontal, Prefrontal, Supratemporal, Postorbital, Suborbital, Maxilla, Pre- 
maxilla, Hyomandibular, Os quadratum, Suprascapula, Operculum, Sub- 
Operculum, Jugular, Spiracular Ossicles, and Supratemporal Ossicles. 
Plates are given, executed in the first style of art by Mr. Joseph Dinkel, 
of Glyptolcemus Kinnairdi, PJianeropleuronAndersoni, which are described 
by Professor Huxley. Sir P. Egerton figures TristicJiopterus alatus, 
Acanthodes JPeachii, Acanthodes coriaceus, A.Mitclielli, Climatius scutiger, 
Diplacanthus gracilis, and Cheiracanthus laius. 
The importance of this communication on the palfeontological history of 
fishes must be manifest to all of our readers, and we hope that a Table, 
exhibiting the classification of Devonian fishes, showing the genera ranging 
throughout the difterent beds, and thus exhibiting at one view both the 
classificatory and geological aspects of the question, may be speedily 
given by the learned professor, whose work Ave have read with so much 
pleasure and instruction. 
Revue de Geologie pour VAnnee 1860. By MM. Delesse and Laugel. 
We cannot better explain the object and scope of this work than by 
quoting a portion of the preface. The authors say : — " Every day geology 
extends its empire ; in all civilized countries and their colonies, even in 
the most remote, facts are collected with ardour which may serve to ex- 
plain the history of the earth. It is characteristic of modern science, and 
this observation is especially applicable to the natural sciences, not to pro- 
gress simply by the efforts of some few men of genius, but likewise to re- 
ceive constant impulse by the co-operation of a crowd of observers, some- 
times as obscure as they are devoted. . . . Without a spirit in favour of any 
particular system, without preconceived opinions, we shall endeavour to 
present every year an impartial, faithful, and concise account of the geo- 
logical labours undertaken in every country. We ought to restrict our- 
selves within sufficiently narrow limits. If our work presents any omis- 
sion, we beg that it may not be imputed to any wish of our own ; if it 
contains any inaccuracies, we shall feel obliged by being informed of them. 
We shall receive with gratitude all communications that may enable us to 
improve a work, of which we do not wish to conceal from ourselves either 
the difficulties or imperfection." The well-known industry and ability of the 
authors should lead us to expect that this endeavour would be carried out 
in a satisfactory manner, and we may say with confidence that this Eeview 
for 1860 will be of great service to the students of geology. It must how- 
ever be borne in mind that the authors have chiefiy devoted their atten- 
tion to what has been done out of France, especially in England and Ger- 
many ; and that they do not pretend to give an account of the geological 
memoirs which appear in the widely circulated French publications.
