publisher, at an increased price, and with a considerable improve- 
ment in type, style, and general appearance. The articles have 
also been better than usual, and several deserve special notice. 
Undoubtedly the most important in the January number is the 
excellent paper by Mr. C. J. A. Meyer, ‘On the Correlation of the 
Cretaceous Rocks of the South-east and West of England,’ in which 
the author expresses the opinion that the various groups of strata 
occurring between the top of the “ chalk with flints,” and the base 
of the Atherfield clay, were all in turn “ deposited beneath the same 
ocean without serious break or intermission between them,” therefore 
he does not admit that there was a long lapse of time between the 
deposition of the Lower Greensand and that of the Gault. His 
views are very clearly illustrated by a most ingenious ideal section 
from Folkestone to iyme Regis; and he guards against the possi- 
bility of any misconstruction, by observing that “the strictly 
horizontal arrangement of the groups of strata shown in the section, 
though true for short distances, is therefore probably mcorrect for 
each and all of the groups, if traced throughout their utmost range, 
and must be regarded as merely an approximate arrangement ; 
it beg, probably, as true for sedimentary strata as for forms of 
life, that all origmated at some given point, and that, consequently, 
their lateral extension can seldom be represented by a horizontal 
line.” 
In the same number, Mr. Etheridge gives a notice of the 
important discovery of a number of Labyrinthodont Amphibia in 
the coal-measures of Jarrow Colliery, Kilkenny, and states that 
Professor Huxley has determined them to belong to five genera, 
at least four of which are new. There is also a description of an 
interesting Crustacean—being the first known British species of 
Aiiger,—by the editor, Mr. H. Woodward ; and a very readable 
article ‘On the Raised Beach of Cantyre,’ by Mr. Hull. 
In the February number, Mr. Binney endeavours to prove, in 
a paper on the ‘So-called Lower New Red Sandstones of Central 
Yorkshire,’ that the said rocks are not of Permian age, but belong 
to the Millstone-grit series. Professor Owen gives a description of 
a new Sauroid fish (Thlattodus suchoides) from the Kimmeridge 
Clay of Norfclk. Mr. Searles Wood, jun., commences an article 
‘On the Structure of the 'Thames Valley and of its contained 
Deposits ;’ and Mr. D. Mackintosh makes a grand onslaught on the 
“atmospheric denudation” theory, in a paper entitled ‘The Sea 
against Rain and Frost, or the Origin of Escarpments.’ The author 
of this last paper expresses himself vigorously, even perhaps dog- 
matically ; and says a great deal that is worth reading. He contends 
that the sea is not a levelling agent, that rain and frost are incapable 
of producing cliffs, that the débris under cliffs is of marine origin, 
the majority of the blocks and fragments found ais under
