This small volume "Amenorrhea" consists chiefly of a compilation of one-paragraph abstracts of publications on the subject. To the student who is hoping to find a critical evaluation of the present state of knowledge on amenorrhea, this monograph is very disappointing. It certainly does not measure up to the high standard previously set for publications of the American Lecture Series. There is a short chapter entitled "War Amenorrhea," an unfortunate designation for a functional clinical state that may also occur in peace time. There is another brief chapter entitled "Russian Investigation." More than half of the book is devoted to treatment, which is, admittedly, a difficult subject to present, and one may well sympathize with the authors.
