 one-sixth of the native vegetation consists of ferns, Gymno- 

 gramme Sadlerioides and Acrostichium Helleri are figured in the 

 report. 



— Among the ever increasing number of books concerning the 

 out- door world, a prominent place must be given to a charming 

 little volume by Thomas Wentworth Higginson, entitled The 

 Procession of the Flowers and Kindred Papers.* In this book of 

 170 pages, the author has brought together six very felicitous 

 sketches of nature in New England, entitled "The Procession of 

 the Flowers," "April Days.'" "Water Lilies," "My Out-Door 

 Study," "The Life of Birds," and "A Moonglade." Those who 

 see the book will wish to read it, and those who read it will want 

 to own it. It is worthy a place in the library of every one who 

 loves nature. 



— Students of lichens in America have always been greatly 

 handicapped in their work for want of a proper treatise on the 

 subject. With the exception of Tuckerman's publication, now 

 considerably out of date, almost nothing has. been written upon 

 this class of plants. Lichenologists will be inclined to give a 

 cordial reception to the recently issued Text- book of Lichenology f 

 by Dr. Schneider, in which the subject has been very thoroughly 

 treated. The work is divided into two parts, the first dealing 

 with the history, general morphology and physiology of Lichens, 

 and the second with the classification and special morphology of 

 the plants. In the first part, symbiosis, reproduction growth, 

 mechanics, chemistry, etc. , of lichens is fully discussed, while 

 the second contains excellent keys to the families and genera. 

 Those who are studying the lichens will find this book invaluable. 

 In addition to 230 royal octavo pages of text, there are 76 full- 

 page plates illustrating all the genera.
