THE PROS AND CONS OF VIVISECTION _All rights reserved_ [Illustration: "LA MORT." _By Bartholomé in Père Lachaise, Paris._ _Frontispiece._] THE PROS AND CONS OF VIVISECTION BY DR CHARLES RICHET PROFESSOR OF PHYSIOLOGY IN THE FACULTY OF MEDICINE PARIS WITH A PREFACE BY W. D. HALLIBURTON, M.D., LL.D., F.R.S. PROFESSOR OF PHYSIOLOGY, KING'S COLLEGE, LONDON LONDON DUCKWORTH & CO. 3 HENRIETTA STREET, COVENT GARDEN 1908 PREFACE To scientific readers, Professor Charles Richet needs no introduction, but to the public at large it may be necessary to mention that he is one of the best known of French physiologists. He has occupied for a good many years the Chair of Physiology in the Faculty of Medicine in Paris, and he has contributed greatly to the progress of the science to which he has devoted his life; some of his discoveries are alluded to with all modesty in the pages which follow. He is, moreover, a man of great erudition, and has been wisely selected to be the editor of a monumental work, _Le dictionnaire de physiologie_, which is issuing from the press to-day. Professor Richet has given particular attention to the study of the psychological side of physiology, and his views on pain will be read as coming from one who is specially fitted to deal with this and other mental phenomena. I therefore consider it a great honour that Professor Richet should have asked me to write a preface to his most interesting and convincing book on the Pros and Cons of Vivisection, and it is a great pleasure to me to commend its thoughtful perusal to all who are interested in the subject.
