by the character of his studies, is better fitted to deal with words 
or with dreams than with things, and would shine much more in 
fanciful interpretations of myths than in the sober domains of 
Natural Science.

In few sciences is an annual record or general summary of 
work done so needful as in geology. So wide and so manifold 
is the subjedt, so closely blended with physics and chemistry 
upon one side and with biology upon the other, and so numerous 
are the organs in which matter of geological interest may first 
see the light, that without some journal like the one before us 
it is scarcely possible for the student to keep himself abreast of 
the current of discovery. We hope, therefore, that there may be 
no question as to the success of so necessary an undertaking. 
The information given is arranged under the following 
heads: — Stratigraphical and Descriptive Geology, Physical 
Geology, Applied and Economic Geology, Petrology, Mine- 
ralogy, Palaeontology, Maps and Sections, Miscellaneous and 
General. Most of these classes are again subdivided, and each 
such division is placed in the hands of a responsible sub-editor, 
To extradt even a tithe of the interesting matter contained in 
the work would be of course impossible, but we may, as speci- 
mens, lay a few fragments before our readers. G. Krefft, in his 
“ Remarks on Prof. Owen’s Arrangement of the Fossil Kanga- 
roos,” considers that the whole of the Australian marsupials, 
extindl and living, are descendants of an extindt animal com- 
prising the dental structure both of the carnivorous and herb- 
ivorous sections of the sub-order, and of which Thylacoleo was 
the last representative. 
O. C. Marsh, in a paper on a “ New Order of Eocene Mam- 
mals ” contained in the “ American Journal” (vol. ix., p. 221), 
gives an account of the Tillotherium, which combines the cha- 
racters of Carnivora, Ungulata, and Rodentia. This is another 
of those discoveries which so powerfully support the dodtrine of 
Evolution, presenting, as they do, characters in combination 
which have been since separated out and distributed among 
different animal groups. 
Riitimeyer’s work, “ Traces of Man in Swiss Interglacial De- 
posits ” (“ Verhand. Nat. Ges. Basel,” vi., 333 to 342), describes 
wooden rods, artificially sharpened, and remains of coarse wicker-
