Reinke's Discussions of Lichenology. 



By Albert Schneider. 



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.
