This unique text should have an appeal to interns, residents and practitioners. Part one, on "The Diagnostic Survey," is designed to give the reader an idea of the probability factor in diagnosis. Unfortunately, this is not especially valuable in individual cases. Part two deals with the differential diagnosis of presenting symptoms as related to the various systems. Part three is an essay on physical diagnosis, while part four embodies common laboratory procedures. In part five, which constitutes one half the book, the diagnosis of various diseases according to systems of the body is dealt with. The book is replete with excellent photographs and drawings. There are many tabulations that make for easy reference.
