SAUNDERS’ MEDICAL HAND-ATLASES A SERIES OF BOOKS OFFERING A SATISFACTORY SUBSTITUTE FOR ACTUAL CLINICAL WORK SPECIAL OFFER A it is impossible to realize the beauty and cheap- ness of these atlases without an opportunity to ex- amine them, we make the following offer: Any one of these books will be sent to physicians, carriage prepaid, upon request. If you want the book, you have mere- ly to remit the price; if not, return the book by mail. A Descriptive Catalogue of all our Publications Sent on Request W. B. SAUNDERS COMPANY 925 Walnut Street Philadelphia LONDON: 9, Henrietta Street, Covent Garden 2 SAUNDERS’ MEDICAL HAND-ATLASES SAUNDERS’ MEDICAL HAND-ATLASES N planning this series of books arrangements were made with representative publishers in the chief medical centers of the world for the publication of translations of the atlases in thir- teen different languages, the lithographic plates for all being made in Germany, where work of this kind has been brought to the greatest perfection. The enormous ex- Moderate pense of making the plates being shared by Price the various publishers, the cost to each one was reduced approximately to one-tenth. Thus, by reason of their universal translation and reproduction, affording international distribution, the publishers have been enabled to secure for these atlases the best artistic and profes- sional talent, to produce them in the most elegant style, and yet to offer them at a price heretofore unapproached in cheapness. One of the most valuable features of these Substitute atlases is that they offer a ready and satis- for Clinical factory substitute for clinical observation. Observation Such observation, of course, is available only to the residents in large medical centers ; and even then the requisite variety is seen only after long years of routine hospital work. To those unable to attend important clinics these books will be absolutely indispensable, as presenting in a complete and convenient form the most accurate reproduc- tions of clinical work, interpreted by the most competent of clinical teachers. Adopted by As an indication of the great practical value U. S. Army of the atlases and of the immense favor with which they have been received, it should be noted that the Medical Department of the U. S. Army has adopted the ‘‘Atlas of Operative Surgery’ as its standard, and has ordered the book in large quantities for distribution to the various regi- ments and army posts.

JUST READY Preiswerk’s atlas will be found invaluable to the practicing dentist, for the numerous excellent lithographs make very easy of comprehension those pro- cedures that would be but imperfectly understood from description alone. The text, nevertheless, is unusually complete, and the translation into English has been done with great fidelity and smoothness. The editor, Dr. George W. Warren, has added much new matter. Hecker, Trumpp, and Abt on Children Atlas and Epitome of Diseases of Children. By Drs.‘R. Hecker and J. TRumpp, of Munich. Edited, with additions, by Isaac Ast, M.

READY SOON It is a recognized fact that the Germans lead the world in the treatment of children’s diseases, and this magnificent atlas fully maintains this’ reputation The lithographic plates are wonderfully accurate, and the accompanying text is particularly full on treatment. Dr. Isaac Abt, the editor, has greatly im- proved the work by the addition of all the latest methods of treatment and diagnosis. Each volume contains from 50 to 100 colored plates 4 SAUNDERS’ MEDICAL HAND-ATLASES Zuckerkandl and DaCosta’s Operative Surgery Second Edition, Revised and Greatly Enlarged Atlas and Epitome of Operative Surgery. By Dr. O. ZUCKERKANDL, of Vienna. Edited, with additions, by J. CHat- MERS DaCosta, M. D., Professor of the Principles of Surgery and Clinical Surgery, Jefferson Medical College, Philadelphia. With 4o colored plates, 278 text-cuts, and 410 pages of text. Cloth, $3.50 net. ADOPTED BY THE U. S. ARMY In this new edition the work has been brought precisely down to date. The revision has not been casual, but thorough and exhaustive, the entire text having been subjected to a careful scrutiny, and many improvements and additions made. A number of chapters have been practically rewritten, and of the newer operations, all those of special value have been described. The number of illustrations has also been materially increased. Sixteen valuable lithographic plates in colors and sixty-one text-figures have been added, thus greatly enhancing the value of the work. There is no doubt that the volume in its new edition will still maintain its leading position as a substitute for clinical instruction. OPINIONS OF THE MEDICAL PRESS Philadelphia Medical Journal “The names of Zuckerkandl and DaCosta, the fact that the book has been translated into 13 different languages, together with the knowledge that it is used in the United States Army and Navy, would be sufficient recommendation for most of us.”” Munchener Medicinische Wochenschrift “We know of no other work that combines such a wealth of beautiful illustrations with clearness and conciseness of language, that is so entirely abreast of the latest achievements and so useful both for the beginner and for one who wishes to increase his knowledge of operative surgery.” Each volume is edited, with additions, by a leading specialist SAUNDERS’ MEDICAL HAND-ATLASES 5 Helferich and Bloodgood’s Fractures and Dislocations Atlas and Epitome of Traumatic Fractures and Dis- locations.

SHOWING DEFORMITY, X-RAY SHADOW, AND TREATMENT This department of medicine being one in which, from lack of practical knowledge, much harm can be done, and in which in recent years great importance has obtained, a book, accurately portraying the anatomic rela- tions of the fractured parts, together with the diagnosis and treatment of the condition, becomes an absolute necessity. This present work fully meets all requirements. As complete a view as possible of each case has been presented, thus equipping the physician for the manifold appearances that he will meet with in practice. The illustrations show the visible external deformity, the X-ray shadow, the anatomic preparation, and the method of treatment. OPINIONS OF THE MEDICAL PRESS Medical News, New York “‘ This compact and exceedingly attractive little volume will be most welcome to all who are interested in the practical application of anatomy. The author and editor have made a most successful effort to arrange the illustrations that the interpretation of what they are intended to present is exceedingly easy.” Brooklyn Medical Journal “« There are few books published that better answer the uirements for illustration than this work of Professor Helferich. . . . Such a collection of illustrations must De the result of much labor and thought.” They are Satisfactory Substitutes for Clinical Observation 6 SAUNDERS’ MEDICAL HAND-ATLASES Sultan and Coley’s Abdominal Hernias Atlas and Epitome of Abdominal Hernias. By Privart- DOCENT Dr. GrorG SULTAN, of Géttingen. Edited, with addi- tions, by Witu1am B. Corey, M. D., Clinical Lecturer on Sur- gery, Columbia University (College of Physicians and Surgeons), New York. With rrg illustrations, 36 of them in colors, and 277 pages of text. Cloth, $3.00 net. DEALING WITH THE SURGICAL ASPECT This new atlas covers one of the most important subjects in the entire domain of medical teaching, since these hernias are not only exceedingly common, but the frequent occurrence of strangulation demands extraordi- narily quick and energetic surgical intervention. During the last decade the operative side of this subject has been steadily growing in importance, until now it is absolutely essential to have a book treating of its surgical aspect. This present atlas does this to an admirable degree. The illustrations are not only very numerous, but they excel, in the accuracy of the portrayal of the conditions represented, those of any other work upon abdominal hernias with which we are familiar. The work will be found a worthy exponent of our present knowledge of the subject of which it treats. PERSONAL AND PRESS OPINIONS Robert H. M. Dawbarn, M. D., Professor of Surgery and Surgical Anatomy, New York Polyclinic. “I have spent several interested hours over it to-day, and shall willingly recommend it to my classes at the Polyclinic College and elsewhere.” Boston Medical and Surgical Journal “ For the general practitioner and the surgeon it will be a very useful book for reference.
