Much of the present volume is, in a measure, the outcome of a thorough revision, remodelling and simplification of the various articles contributed by the author to Pepper's System of Medicine, Buck's Reference Handbook of the Medical Sciences, and Keating's Cyclopaedia of the Diseases of Children. Moreover, in the endeavor to present the subject as tersely and briefly as compatible with clear understanding, the several standard treatises on diseases of the skin by Tilbury Fox, Duhring, Hyde, Robinson, Anderson, and Crocker, have been freely consulted, that of the last-named author suggesting the pictorial presentation of the "Anatomy of the Skin." The space allotted to each disease has been based upon relative importance. As to treatment, the best and approved methods only--those which are founded upon the aggregate experience of dermatologists--are referred to. For general information a statistical table from the Transactions of the American Dermatological Association is appended. H.W.S. CONTENTS.
