The author has departed from the beaten track of the usual text-book on sanitation and subjects are introduced which are of interest not only to health officials, but to the laymen, for example, the topics of milk and food supplies, car sanitation, etc. All the subjects considered are dealt with concisely and clearly, the limited scope of the work precluding any lengthy dissertations. The chapter on the cause and prevention of contagious and infectious diseases is excellent. The author's views are in consonance with those of advanced thinkers and practical sanitarians. This little work is commended.
