Reviews—The Geological Survey of England and Wales, 275 
has been given of them. Some older rocks are exposed in the area, 
the Wenlock Beds and Lower Old Red Sandstone (associated with 
the Cheviot porphyrite), but they occupy small areas, and require but 
brief notice. 
The Carboniferous rocks are grouped as follows :— 
Upper Series. Calcareous Division. 
CO ae Carbonaceous Division (Scremerston Beds). 
Series Fell Sandstones. 
Lower Series. ) Tuedian Division, or | Cement-stone Beds & Roth- 
| Tweed Beds. bury Limestones. 
Lower Freestones. 
Basement Beds. 
The Basement Beds are probably on the horizon of strata else- 
where grouped as Upper Old Red Sandstone. They consist of 
conglomerates made up of porphyrite and Silurian greywacke. The 
overlying rocks are described in much detail, many sections being 
given to show the position of the principal beds of limestone, coal, 
etc. Separate chapters are devoted to the Faults, and to the 
Palzontology, the fossils having been identified chiefly by Messrs. 
G. Sharman and EH. T. Newton. Other chapters are devoted to the 
Jeneous rocks, to Glacial Phenomena, Post-Glacial deposits, and to 
the Physical History of the district. The Economic deposits, Springs, 
Mineral Waters, etc., are duly noticed, and in Appendices there is an 
account of the Bibliography, together with a Glossary of Local Terms, 
and Records of Borings and Sinkings.

In this Memoir accounts are given of the Upper Crag (which is 
rarely fossiliferous in the area), of Chillesford Clay, Pebbly Series, 
Glacial and Post-Glacial Drift, and Alluvium. The deposits which 
have attracted most attention are those included as Post-Glacial, the 
term being used to imply that the beds are newer than the Glacial 
Drifts of the district. These are the famous Hoxne deposits, which 
have yielded many Paleolithic implements. Their precise age with 
reference to the newer Glacial deposits of the north of England 
may be regarded as an open question: but Mr. Dalton remarks that 
“The mere presence of land and freshwater shells, bones, and plants 
would suffice to disprove this correlation with any part of the 
Glacial series, which is wholly of marine origin.” We presume he 
refers to the Glacial Drifts of Norfolk and Suffolk, but that they are 
wholly of marine origin is very far from being an accepted dogma. 
A number of records of well-sections conclude this work; these 
give accounts of the London Clay, Reading Beds, and Chalk, which 
are not exposed at the surface.

Although the area described in this Memoir is a small one (being 
less than 50 square miles), it is one of considerable interest to 
students of Pliocene Geology. The cliffs of Dunwich, Haston
