Preface To The Third Edition

The exigencies of practice and other engagements, as well as the enormous literature produced by numerous workers in dermatology in all civilized Countries, have rendered the preparation of this edition a long and arduous task, and the Second Edition has been out of print for the last three years.

It has been my earnest endeavor to bring the work up to date. Many of the articles have been entirely rewritten, and all have been thoroughly revised, and often in great part recast ; nevertheless the book has grown considerably, but as my aim has been to make it as clinically complete as possible, the < rowth has been almost entirely on this side. The original | ^n of the work has, however, been preserved, so that the student can without trouble at first confine his attention to the most important features of the commonest diseases, while he can use it as a work of reference as his practical knowledge increases (vide p. 31).

A few of the names of the diseases have been changed from the last edition, such as Dermatitis herpetiformis for Hydroa herpetiformis, Lichen acuminatus instead of Pityriasis rubra pilaris, etc.; but this has been almost entirely in the interests of uniformity of nomenclature, these being the names which have met with the most general acceptance. A very few other changes have been made for other reasons.

The following are among the new articles: Acrodermatitis perstans, Persistent balanitis, Cheilitis exfoliativa, Lichen annulatus, Erythema serpens and Erysipeloid, Erythema elevatum diutinum, " Gayle " in man, X-Ray dermatitis, Toxin Serum Eruptions, Bronzing of the Skin in Diabetes, Keratolysis exfoliativa congenita, Porokeratosis, Mai de Meleda, Lupus marginatus, Granuloma annulare, Granuloma inguinale tropicum, Granuloma pyogenicum, Sarcoid, Mortimer's Malady; Pseudo-xanthoma elasticum, Leukaemia and Pseudo-leukaemia cutis,

6 ' PREFACE TO THE THIRD EDITION.

Chloroma, Endothelioma capitis, Veld sore; Hydrocystoma, Milium congenitale, x\cne keratosa, Acne necrotisans, Acne agminata, Folliclis, Alopecia seborrhoica, Alopecia cicatrisata, Ulerythema ophryogenes, Folliculitis decalvans, Lentigo senilis, Blastomycosis hominis, etc. For most of the above long list, which is not complete, the articles have been short, but there have been many others, such as Erythema scarlatiniforme recidivans, Parakeratosis variegata (Lichen variegatus), etc., which had only a brief mention in the previous edition, but have now had, on account of our increased experience and knowledge of them, to be expanded into comparatively important articles.

With the view of helping my co-workers, numerous references have been given, especially choosing those which best opened up the literature of the subject. References to colored illustrations of most forms of skin diseases have also been given, largely, as is natural, to my own Atlas; but where the particular form of disease was not illustrated there, or where there was an especially good plate in another atlas or article, attention has been drawn to it, so that the reader may be enabled to help himself to realize the description in the text. With this object also a colored plate of the principal syphilids has been introduced, as their diagnosis can be made from a sample of the eruption, better than is the case in most non-specific eruptions where distribution, generally, plays so important a part. Two plates have also been given of the Ringworm Fungi in accordance with the most modern views.

In conclusion, I have to thank Mr. George Pernet, not only for assisting me in reading the proofs and other help while the book has been passing through the press, but for cordial and indefatigable assistance in sifting the literature of the subject, in preparing the microscopical sections for the new illustrations, and for writing the section in the Appendix on the Staining of Micro-organisms. My thanks are also due to Mr. Harold Wilson, B. Sc, Head Dispenser at University College Hospital, for reading the proofs of the formulary at the end, to prevent pharmaceutical errors being passed over.
