Geschichte der biologischen Theorien

Abstract

THE author of this scholarly work attaches great importance to the cultivation of the historical sense among biologists, believing that progress is impeded because there is relatively little of it, and one of the aims of his book is to stimulate a study of the history of the science. To this end it is admirably adapted. It is learned, but at the same time wisely selective; it is at once appreciative and critical; and it is written in a fresh, interesting way. We had the pleasure of welcoming the first volume, published four years ago, which dealt with ancient history, and we would congratulate the author again on the success with which he has accomplished a very difficult task in dealing with what has occurred in biology, or in biological aetiology, since the end of the eighteenth century. It seems to us, indeed, that the author has added to his strength since he completed the first part of his great \vork.
