is extensively covered with drift ; and a detailed account is given of

(4) The Water Supply of Suffolk from Underground Sources, 



WITH Records of Sinkings and Borings. By W. Whitaker, 

 B.A., F.R.S., with contributions by H. F. Parsons, M.D., 

 H. K. Mill, D.Sc, and J. C. Thresh, D.Sc. 8vo ; pp. 177, 

 with map. (1906. Price 3s. 6c?.) 



In this memoir Mr. Whitaker gives a general outline of the 

 water-bearing strata, and summarizes some points of special 

 geological interest in connection with the numerous records of 

 borings. Notable among these records is that of a boring at 

 Glemsford, which proved a thickness of 470 feet of Glacial Drift, 

 much to the perplexity of the well-borer, and of special interest to 

 the geologist as being the greatest recorded thickness of Glacial 

 Drift in Britain. Full details are given of the Stutton boring, 

 which was carried down to a depth of 1,525 feet, reaching Paleeozoic 

 rocks beneath the Gault. The records deal mostly with wells or 

 borings for water, and analyses of water are appended. Dr. Mill 

 contributes a map and statistics relating to the rainfall. 



(5) Water Supply of the East Riding of Yorkshire, from 



Underground Sources, with Records of Sinkings and 



Borings. By C. Fox-Strangways, F.G.S., with contributions 



by H. R. Mill, D.Sc. 8vo ; pp. 181, with map and 3 



illustrations. (Price 3s.) 



This memoir contains an outline of the geology of the East 



Riding and of portions of the Vales of York and Pickering, with 



especial reference to the water-bearing strata. It contains records of 



all known sinkings and borings in the area, together with analyses 



of waters, and a bibliography. There is also a section on the 



rainfall with a colour-printed map, by Dr. Mill. 



(6) Soils and Sub- Soils from a Sanitary Point of View. With 



especial reference to london and its neighbourhood. 



By Horace B. Woodward, F.R.S. 8vo; pp. 58, with 



18 illustrations and colour-printed map. Second edition. 



(Price Is. 6cZ.) 

 •The object of this work has been to supply information regarding 

 sites for houses and other questions involving the applications of 

 geology to sanitary science ; and it includes notes on sewage-farms 

 and cemeteries. In this second edition the chapter treating of water- 

 supply and drainage has been enlarged, with especial reference to the 

 residential areas within easy reach of the Metropolis. A new colour- 

 printed map on tlie scale of an inch to four miles is given in the 

 memoir. It includes Guildford, Sevenoaks, Chelmsford, and 

 Rickmansworth.
