31. — The Geology of the Country between Atherstone and 

 Charnwood Forest. By C. Fox-StranCxWAYs, F.G.S. With 

 Notes on Chaknwood Forest by Professor W. W. Watts, 

 M.A., F.G.S. 8vo ; pp. 102. (London : printed for H.M. 

 Stationery Office, 1900. Price 2s.) 

 f pmS Memoir, which has been written in explanation of the New 

 1 Series map, Sheet loo, contains a good deal of detailed 

 information of practical value respecting the northern part of the 

 Warwickshire Coalfield and the southern part of the Leicestershire 

 Coalfield. A number of records of borings and sinkings are given. 

 Professor Watts contributes a summary of the interesting observations 

 which he made while mapping in detail the old rocks of Charnwood 

 Forest. These he groups in the ' Charnian System,' whose position 

 in the great Pre-Cambrian sequence cannot at present be determined. 

 Among the other rocks dealt with by Mr. Strangways are the 

 tStockingford Shales (Cambrian), the Permian and Trias, the Glacial, 

 and more recent deposits. With the aid of Mr. Whitaker he con- 

 tributes a useful geological bibliography of Leicestershire.

1. "Additional Notes on the Drifts of the Baltic Coast of 

 -Germany." By Professor T. G. Bonney, D.Sc, LL.D., F.R.S., F.G.S., 

 and the Eev. E. Hill, M.A., F.G.S. 



The authors, prior to revisiting Riigen, examined sections of the 

 Drift to the west of Warnemiinde, with a view of comparing it with 

 that of the Cromer coast. Where the cliffs reach their greatest 

 elevation, two or three miles from that town, they are composed of 

 a stony clay, which occasionally becomes sandy. At intervals, 

 however, sand interbanded with clay occurs, filling what appear to 

 be small valleys in the Drift. A layer of grit and stones, occasionally 

 associated with a boulder, occurs once or twice between these sands 

 and clays. The valleys are excavated in the great mass of stony 

 clay which extends for four or five miles to the west of Warnemiinde; 

 and the synclinal slope of the layers and the contortion of the under- 

 lying bedded sands indicate that the mass filling them has been let 

 down as a whole, either by solution of the Chalk beneath the Drift 

 or by the melting of underlying ice. Of these two hypotheses the 

 authors view the latter with the more favour, but it also has its 

 difficulties. 



In Eiigen, Arkona was visited ; here Chalk occurs, apparently as 

 a sort of island in the Drift. At the well-known locality by the 

 lighthouse it seems to overlie a drift, but on closer examination the 

 latter appears more probably to have filled a cavity excavated in the 

 Chalk, this apparent inlier of Drift probably being only a remnant 

 of a much larger mass; therefore it is likel}' that this part of the
