Medical Embryology: Human Development, Normal and Abnormal , ed. 2, by Jan Langman, M.D., Ph.D. Baltimore: The Williams and Wilkins Company, 1969, 386 pp., $7.50

This book is the second edition of a compact and well written embryology text aimed primarily at the medical student. The broad acceptance of the first edition is evidenced by the translations into Spanish, French, Dutch, Portuguese, Italian, Japanese, Persian, and Korean. The second edition contains a new chapter on experimental embryology, as well as up-dating of the entire book. Compared with some of the older texts, this one is shorter, less expensive, and easier to read, and it dwells less on bizarre malformations—the "monsters" which seemed to fascinate some embryologists.
