Epidemics, Plagues, and Fevers. By the Hon. Rollo Russell. (E.
Stanford.)—This volume is described by the author as "an epitome of existing knowledge concerning the nature and pre- vention of maladies commonly spoken of as 'preventable.' " He gives in alphabetical order an account of nearly thirty diseases, beginning with "cholera," and ending with "yellow-fever." All the information given has been gathered from the best sources and kept up to the latest date, and the whole collection will be found of considerable value. The book is intended, it should be explained, not for professional students, but for persons who may happen to be called upon, as members of sanitary committees, as school-managers or schoolmasters, or as employers of labour, to deal with the subject. Is it really established beyond doubt that no epidemic is communicated by the atmosphere ? Very remark- able facts have been stated about measles ; for instance, whole villages have been simultaneously prostrated by attacks.
