JOHN WRIGHT AND CO., PRINTERS AND PUBLISHERS, BRISTOL. AUTHORS’ PREFACE. As it is evident in the numerous recent publications on Leprosy that our first work on the disease, which was published in Norwegian, is unknown to many investigators, and as there appear in their publications many statements, to our thinking, premature and founded on insufficient knowledge, we think it desirable to present a comprehensive statement of the result of our studies of this disease, so interesting in itself and so instructive in other directions. Since one of us has been for more than twenty years occupied in dealing with the disease, we hope to be able to lay before experts a thorough, complete and instructive demonstration, the more, as we do not base our views, as has been frequently and unfortunately done, on any single or scattered observations. TRANSLATOR’S PREFACE. In the translation of this little work I have, of course, made absolute accuracy of meaning my first aim. It presents the views of one who in his knowledge and experience of the disease is probably second to none. There are, of course, certain points on which there is much difference of opinion. For example, Hansen’s view, which is very widely held, of the position of the bacilli in the cells, is very strongly opposed by Unna. Then as to the occurrence of nodules on the palms and soles which Hansen denies, Unna remarks that it is quite exceptional, while Hillis seems to consider it by no means rare. The chapter on Treatment has been wholly re-written for this edition, and is practically a summary of the late Dr. Danielssen’s views. The photographs are a further addition to the original German edition. It has been pointed out to me that Dr. Hansen does not refer to the recent Indian Commission. His views on it may be found in the _Lancet_, of October, 1893. In conclusion, I have to thank my friends, Dr. Colcott Fox for a general reading of the proofs, and Drs. George Mackay and Stockman for their revision of those parts relating to the affections of the eye and to the drugs used in treatment. NORMAN WALKER. EDINBURGH, _May, 1895_.
