Fighting Dirt : the World's Greatest Warfare. By Ernest Hood.

(G. G. Harrap. is. Ed.)—Mr. Hoed, who is a Head-Master at Southend, has written a " hygiene reader " of a distinctly novel kind, which ought, as the Master of Christ's says in a prefatory note, " to he in the hands of every teacher of children throughout the country." Mr. Hood represents clean living as a war for the defence of " Body-Fort," and works out his allegory with much vigour and ingenuity, taking illustra- tions from the Great War and weaving in the lessons of medical science concerning bacteria, foul air, flies, drink, and so forth. Ile points out incidentally that the medical officer of health can only do his best work if he has the confidence of his Council and the support of the rate- payers. His book will, we are sure, open the eyes of a good many future citizens to the importance of cavitation.
