The last previous edition of this book was published in 1930. Unfortunately, even the present edition is not quite up to date, since the 1935 edition of New and Nonofficial Remedies served as its basis for drugs not included in the Pharmacopeia or in the National Formulary. Planned essentially as a medical guide for the hospital corpsmen of the Navy Medical Department, the work approximates a household medical work, with chapters on minor surgery and first aid, emergency dental treatment, nursing, hygiene, allergy, the venereal diseases, field sanitation, diets, pharmacy, chemistry, the control of hospitals and many other suggestions. There is valuable information on the use of x-rays, on laboratory procedures and technic, on chemical warfare and on medicolegal problems. Certainly the book must be exceedingly useful, particularly to those members of the Navy Service who are not in immediate contact with medical officers.
