REINKE'S DISCUSSIONS OF LICHENOLOGY.
It is thought advisable to give a review of Reinke's paper on lichenology, because this author is doubtless the most competent advocate of modern scientific lichenology. Although much of the author's discussion is based upon theory and the observations of others, yet the papers are of inestimable value to the special student, and we hope that they will be collected and issued in book form.
Meanwhile it is hoped that this review may be found useful by those English-speaking students who can not readily avail them selves of the original communications.
