 From the Author's Preface to the Second Edition 



" Since the first edition of the present work was published, the num- 

 ber of important investigations on the structure. and development of 

 the Archegoniatae has been so great that it has been found necessary 

 to recast entirely certain portions of the work, this being especially 

 the case with the chapters dealing with the Eusporangiate Ferns. 

 The whole book, moreover, has been carefully revised, and a good 

 deal of new matter introduced, including two special chapters on the 

 geological history of the Archegoniates, and the significance of the 

 alternation of generations.

 " It seems to me that it will form an admirable handbook for uni- 

 versity work where one wishes in brief form a treatment of the sub- 

 ject to cover all phases of the subject. The illustrations are excellent, 

 and the matter is presented with the forcefulness which is character- 

 istic of its author." — G. F. Atkinson, Professor of Botany, Cornell 

 University.

 "Books of this kind are exceedingly useful, and there should be more 

 of them. . . . The book is full of interest and suggestion, and com- 

 mends itself not only to those who wish a reading knowledge of 

 botany, but also to teachers of botany." — Botanical Gazette.
