American Pocket Medical Dictionary EDITED BY W. A. NEWMAN DORLAND, A.M., M.D. \\\ ASSISTANT OBSTETRICIAN TO THE HOSPITAL OF THE UNIVERSITY OF PENNSYLVANIA; FELLOW OF THE AMERICAN ACADEMY OF MEDICINE, ETC. CONTAINING THE PRONUNCIATION AND DEFINITION OF OVER 26,000 OF THE TERMS USED IN MEDICINE AND THE KINDRED SCIENCES, ALONG WITH OVER 60 EXTENSIVE TABLES PHILADELPHIA W. B. SAUNDERS 925 Walnut Street 1898 Copyright, 1898, W. B. SAUNDERS. ELECTROTYPED BY WESTCOTT & THOMSON, PHILADA. PRESS OF W. B. SAUNDERS, PHIUADA. PREFACE. This small volume is the outcome of a need for a pocket dictionary which, though handy in size, should be so full and complete as to supply the wants of the practising physician no less than those of the student of medicine. It is not the editor’s intention to attempt to take the place of the larger dictionaries indispensable to a thorough understanding of the language of medicine, hut he has striven to develop the possibilities of the pocket lexicon to a degree not heretofore attained. The chief aim has been to make the selection of words as complete as possible. To this end the larger diction- aries have been freely used, and a systematic gleaning has been made through the latest medical literature, so that the vocabulary may be said to be strictly up to date. Of necessity the definitions of terms are brief, but the en- deavor has been to make them clear, adequate, and to the point. The order of arrangement of matter is strictly alpha- betical. In cases of a phrase, consisting of a noun and qualifying adjective, the definition will usually be found under the noun, under which all the phrases containing that noun have been grouped. Besides the ordinary dictionary words it has seemed desirable to insert a considerable amount of matter in tabular form. This matter, it is believed, will prove of value to students for memorizing in preparing for exam- inations, besides serving to group correlated facts in a convenient form for quick consultation.
