Hygiene. By J. Lane Notter, M.A., and R. H. Firth.

(Longmans.) —" We have endeavoured," say the authors in their preface, "to consider the general laws of health, the causes of disease and the means of combating them, in the simplest language, and by divesting them, where possible, of scientific technicalities, to make clear, even to non-scientific readers, those great natural laws and processes upon which our healthy life so much depends." " Hygiene," as Messrs. Netter and Firth point out, is a very wide subject ; to be treated adequately, it requires much scientific knowledge. So much will be seen from a bare enumeration of the main topics here handled,—Air, Water, Food, Seib, Sites and Buildings, Removal of Refuse and Excreta, Personal Hygiene, Infection and Disinfection, Parasites, Climate and Weather, Vital Statistics.—One of these points is treated with fullness in The Sanitary Arrangement of Dwelling-Houses, by A. J. Wallis-Taylor, C.E. (Crosby Lockwood and Son). An appendix gives the Public Health Acts of 1875 and 1891, and other useful matter.
