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.
