or in tliose of the School of Mines or other public institutions,. and 
also notices of all the new researches on the metamorphism and 
modifications of rocks. The work is compiled with the same care 
as the previous volumes, and reflects much credit on the pains taken 
in rendering in a Condensed form the notices and abstracts so very 
useful and instructive ; for, witliout this aid, it would be impossible 
for any ordinary Student to become acquainted with the wide ränge 
of geological literature. The subjects are systematically arranged 
under lithological, historical, geographical, and dynamical geology, 
besides notices of general works on the subject. Some attention is 
also given to memoirs on economic geology, and a neatly-executed 
coloured map is given by M. Delesse. This map, designed M. Ae. 
Babinski, although on a small scale, shows in a simple and striking 
manner the agricultural resources of France, and the relative values 
of the dilferent districts, and the distribution of the vineyards, 
commons, and forests. J. M.

“ On the Geological Significance of the Boring at Messrs. 
Meux’s Brewery, London.” By Robert A. C. Godwin-Austen, 
F.RS., Y.P.G.S., etc. Read before the British Association at 
Plymouth (Section C.). 
The author commenced by pointing out that it was very generally 
known that tliis undertaking, after passing through a great thickness 
of Challc, met with a very insignificant representative of the sands 
wliich underlie the Chalk in the south-east of England, thence at once 
passed into strata which, by characteristic fossils, were identified as 
Palaeozoic, and of Upper Uevonian age. This was just as had been 
anticipated as to the absence of any portion of the Oolitic series there, 
and confirmed wliat many years since had been supposed to be the 
subterranean structure of the South of England ; indeed, it might 
fairly be stated that geologists generally have been of opinion that a 
band of Palmozoic rocks extended from Westphalia westwards, and 
passed somewhere beneath the Secondary formation of the south-east 
of England. The importance of determining the course of such 
Paheozoic band was, that along the wliole of the exposed part of its 
course, as from its extreme eastern place to near Yalenciennes, it 
had dependent on it on the north the productive Coal-measures of 
Westphalia, Belgium, and the North of France. From Valenciennes 
westwards the Coal-measures were not exposed at the surface, but 
were reached beneath the Chalk formation, and from the Underground 
workings the relations of the several members of the Palseozoic series 
were known to correspond exactly with those where the series were 
exposed, as was the case, also, where it was again seen at the sur- 
face in the Boulonnais, and at sundry other valleys of elevations 
along the axis of Artois. The wliole of the Coal-measures of Belgium 
and North of France must be understood as occupying a trough 
formed out of the older members of the great Palaeozoic series, and 
the explanation given of the preservation of this extended and
