86 Reviews — Memoirs of the Geological Survey. 



found at March in Cambridgeshire is added. A description of the 

 Post-Glacial deposits and their organic remains, contains the observa- 

 tion that Felis spelcea and perhaps Eleplias primi genius are true 

 Post-Glacial species. The Lion has been found at Hornsea, associated 

 with the Irish Elk, Horse, and Bed-Deer, apparently in the ancient 

 deposits of the Mere. 



A chapter is devoted to the changes now in progress. The serious 

 loss of land along the coast-line within historic times is well known, 

 and this is clearly illustrated by diagrams or reproductions of charts 

 dating from 1684. Since this period the average rate of advance of 

 the sea has in places been about 1\ yards a year. In other places 

 land has been gained. 



A concluding chapter gives an account of the Economic Geology — 

 soils, brickmaking, etc., with some mention of the Humber Tunnel. 

 The Water-supply is also discussed, and details of a number of Well- 

 sections and Borings are given. An appendix contains a list of 

 works on Holderness. 



2. The Geology of Bridlington Bat. By J. B. Dakyns and 

 C. Fox-Strangways. 8vo. pp. 18. (London, 1885.) Price Is. 



THIS is a brief explanation of Quarter-sheet 94 N.E. of the Geo- 

 logical Survey Map. It includes an account of the Chalk, 

 Glacial and Post-Glacial Beds. Mr. Beid contributes the List of 

 Fossils from the Bridlington Crag. 



3. The Geology of the South-West Part of Lincolnshire, with 



Parts of Leicestershire and Nottinghamshire. By A. J. 

 Jukes-Browne, B.A., F.G.S. (Parts by W. H. Dalton, F.G.S.) 

 8vo. pp. 180. (London, 1885.) Price 4s. 



THIS is a description of the rocks embraced in the area of Sheet 

 70 of the Geological Survey Map. The area was chiefly 

 surveyed by the late Mr. W. H. Holloway, other portions being 

 mapped by Messrs. W. H. Penning, W. H. Dalton, and A. J. Jukes- 

 Browne. The rocks include the Upper Keuper Marls, the Bhastic 

 Beds, the Lias, the Oolites from the Northampton Sand to the 

 Kimmeridge Clay, and various Glacial and Post-Glacial deposits. 



Detailed descriptions of the strata are given, and the palasonto- 

 logical divisions, with lists of fossils, are duly noted. The junction 

 of the Lower with the Middle Lias is taken at the top of the clays 

 with Ammonites capricornits : so that a number of forms regarded as 

 Middle Lias in Dorsetshire are now placed in the Lower Lias. 

 This higher line was adopted by Prof. Judd in the Butlandshire 

 district, and hence it was desirable to continue it northwards. 

 Ammonites communis is noted from the Middle Lias, so that our 

 notions of the value of Ammonites as indices of zones are liable to 

 be shaken. It is remarked that the zones of Ammonites Humphries- 

 ianus and A. Parlnnsoni are altogether absent from Lincolnshire, unless 

 the former is represented by the upper portion of the Lincolnshire 

 Oolite. 



The Glacial deposits include representatives of the Chalky Boulder-
