Underground Waters for Commercial Purposes, by F. L. Rector. 
New York : J. Wiley & Sons ; London : Chapman & Hall. 98 pp., 4s. 6d. 
net. This book is written for readers in America, where in 1911 there 
were 732 springs, with a combined output of 63,923,119 gallons of mineral 
waters, and we fear it will not appeal very much to the English public. 
It deals with springs, wells, properties of water, and its chemical, bac- 
teriological, and microscopical examination. Four and sixpence seems 
rather a lot for fewer than a hundred small pages, and the copy sent to 
us is bound upside down. 
The Petrol'gy of the Sedimentary Rocks, by F. H. Hatch and R. H. 
Rastall. London: G. Allen & Co., pp. xvi. +425, 7s. 6d. net. This is 
the second volume of the authors’ Textbook of Petrology, and deals 
with Deposition in general, Fragmental, Chemical and Organic Deposits, 
Metamorphism, Cementation and Metasomatism, and Weathering, and 
there is a useful appendix on the Systematic Examination of the loose 
detrital sediments, by T. Crook. Examples in illustration are drawn from 
various parts of this country and abroad. There are sixty illustrations 
of rock sections, etc., mostly British. 
Histcry of Geography, by J. Scott Keltie and 0. J. R. Howarth. 
London : Watts & Co., 154 pp., is. This remarkably cheap book should 
enable anyone interested to get a thorough and reliable record of the 
progress in geographical science. The position of one of the authors, 
as Secretary of the Royal Geographical Society, is a guarantee of accuracy. 
The volume deals with Greek and Roman Geography, the Dark Age, 
Portuguese Expansion, the hew World, Polar Exploration, James Cook, 
African Research, Methods of Mapping, etc. It is a wonderful record 
of a wonderful science, and should especially appeal to teachers.
