These two volumes are the third and fourth in the series of books prepared by Vignes on the illnesses that may occur during pregnancy. In volume III the author takes up diseases of the skin and in its seventeen chapters he discusses the entire field of dermatology that may be associated with gestation. Volume IV deals with the afflictions of the mucous membranes of the vagina and cervix. As was emphasized in the review of the first two volumes (The Journal, May 2, 1936, p. 1596) the books are encyclopedic in character. The author has thoroughly reviewed the world literature on the subjects he discusses and he summarizes it in excellent fashion. Large sections of each book are devoted to therapy; hence these books should prove to be of great practical value as well as indispensable sources of reference.
