Β. SAUNDERS COMPANY PHILADELPHIA THE previous edition of this book appeared in 1913. The present edition has been carefully revised throughout, so thoroughly, in fact, that it was nece ary to make entirely new plates for it. Several hundred new terms have been defined, and the text matter has been increased by 30 pages. During the past two years a multitude of new tests, both clinical and laboratory, have been published, with the result that the list of tests in the Dictionary has been greatly increased. This list has grown from ten pages in the original edition to nineteen pages in the present one. This is only a single instance of the constant and rapid increase in the terminology of medical science. The editor has had the benefit of the cod per at i on of a large number of friends of the Dictionary, and he desires to record here his deep obligation for such a istance. THe aim of the author of this work has been to produce, in a volume of convenient size, an up-to-date medical dictionary, sufficiently full for the varied tequirements of all cla es of medical men. Physicians and students have long felt the need of such a work. The book does not claim to be an encyclopedia: it is a dictionary, a concise and convenient word-book, aiming to furnish full definitions of the terms of medicine and kindred branches, and such collateral information as medical men generally would be likely to look for. The author has sought a middle course between the large, unwieldy lexicon and the abridged students’ dictionary, avoiding the disadvantages of each. Special attention has been given to the wording of definitions, with the intention of making them clear, concise, and yet sufficiently complete. Under the more important headings a considerable amount of collateral descriptive matter has been included. For instance, under each drug are given its composition, sources, properties, uses, and dose; under the more important diseases, an account of their etiology, symptoms, etc.; under the principal organs, a description of their structure and function. Besides the ordinary dictionary matter, it has seemed desirable to include a large amount of information arranged in tabular form. In addition to the usual anatomic and clinical tables, there will be found specially prepared tables of Tests, Stains and Staining Methods, Methods of Treatment, etc., which, it is believed, will prove of distinct value. In the arrangement of matter, convenience of consultation has been sought. To this end all phrases consisting of a noun and its qualifying word have been defined under the principal noun: thus, Lateral Sclerosis will be found under Sclerosis; Bas i facial Axis, under Axis; Bartholin’s Duct, under Duct, etc. The important features of pronunciation and derivation have received the most careful attention. The system used for expre ing the sounds is extremely simple, and yet it indicates with accuracy the exact pronunciation of the words. The illustrations of the book have been chosen for their practical value in aiding the text, rather than for their pictorial beauty, the intention being to show to the eye what could be only imperfectly described in words. A special effort has been made to produce a volume of attractive appearance and convenient size, such as a man would want to keep on his desk for constant reference. By the use of a large page with a compact but clear typography it has been po ible to furnish an unusually large amount of matter in a volume of handy size. χ Δ. Accommodation. Acetum. Anode.
