The third edition of "Introduction to Dermatology" by the Suttons is characterized by many new photographs and the addition of descriptions of some forty diseases not included in the previous editions. Although the discussions of some of the diseases are short, descriptions of practically all the diseases of the skin and mucous membranes are included. A liberal amount of space is given to syphilis and its treatment. The only criticism that can be offered is with regard to more adequate discussion of the spinal fluid examinations in syphilitic patients. The book is highly recommended as a manual for the medical student and the general practitioner.
