For the busy man whether practitioner or student, brevity is essential in the make-up of any text-book. So it has been the author's aim to present clearly and concisely the subject of dermatology. To this end an attempt has been made to arrange the general considerations and the special diseases in logical sequence, to properly emphasise the relative importance of symptomatology, aetiology, pathology, diagnosis and treatment, to present lucid and descriptive definitions, to relegate obsolete terms to their proper spheres, and to omit the many unnecessary and confusing foot-notes so characteristic of many scientific books. The subject of treatment is a broad one and is given extensive consideration not only as regards general principles in the introductory portion of the book but also from a specific standpoint under the description of the various disease entities.
