I. — Note sur le terrain Devonien de la Bade de Brest. By 
Dr. Cn. Barrois. (Ann. de la Soc. Geol. du Nord, vol. iv. p. 59.) 
mHE Devonian strata of Britanny are found scattered liere and there 
L in tlie synclinal hollows of the Silurian beds, and have formed 
tbe subject of numerous papers by niany eminent. Frencli geologists. 
They consists of sandstones, grauwaclce, limestones, and schists, 
and are divided by the author into five sections, each cbaracterized 
by its distinct assemblage of fossils. M. Barrois carefully describes 
these several divisions and their contained fauna ; and discusses their 
probable equivalents in otlier regions. His views on this latter 
point will be best gathered froni the following table, which he has 
provisionally drawn up.

II. — The Geologt of the Northern Part of the English Lake

Geological Survey Map of England and Wales.] By J. Clifton 
Ward, F.G.S., etc. 8vo. pp. 132. (London. 1876.) 
T HIS Memoir, the first issued by the Geological Survey in de-

geology of the country around Keswick, including the lakes of 
Ullswater, Thurlmere, Derwentwater, Bassenthwaite, Crummock 
Water, Buttermere and Ennerdale. Mr. Ward commences with a 
brief account of the Physical Geograpliy, and then gives a general 
description of the rocks ; these embrace the Skiddaw Slate, the 
Volcanic Series of Borrowdale (Green Slates and Porphvries), the 
Basement Gonglomerate (offen called Upper Old Bed Sandstone), the 
Carboniferous Limestone, Glacial Deposits and Alluvium. Besides
