A new textbook of pathology is presented by Professor Duval and his associate in the denartment at Tulane University. The prefatory statement promises that it will stress the relationship between pathologic physiology and morbid anatomy, certainly a desirable approach and one too long delayed in almost all the standard textbooks. This promise is not fulfilled. If a pathophysiologic approach is attempted, it would seem desirable that some of the fundamentals underlying the objective manifestations of morbid anatomy would be discussed, so that the student might have some of his incessant "whys?" answered in a fashion that would satisfy his curiosity and permit a build-up for the more complex problems. Unfortunately there is nothing of this sort to be discovered.
If, in the opening chapter, proliferation is discussed, one might at least expect some mention of the physicochemical mechanisms that are involved and which have received such intensive investigation not only
