A Handbook of Hygiene. By A. M. Davies. (C. Griffin

and Co.) —A vast amount of information has been compressed into a small space by the author of this volume, assisted in no slight degree by the publishers, who have given all the help which the best of paper and typography could furnish. Nearly six hundred closely printed pages make a volume (bound in morocco) which weighs less than a pound, and can, for size, be conveniently carried in the pocket. We are not prepared to criticise in detail Mr. Davies's treatise, the value of which, as far as we have been able to examine and appreciate it, is undoubted. On the subject of the comparative merits of water and earth as vehicles for the re- moval of sewage, we are inclined to doubt. We are convinced that wherever it is in any way possible the earth is the better. It is the only hope of keeping our streams pure.
