^ -^ from technicalities. Ihe following 



table of contents indicates, partially, the scope of the work : Introduction ; 



reproduction of ferns ; classification of our ferns ; analytical key, based on the 



fructification ; analytical key, based on the stalks ; ferns of the polypody family ; 



ferns of the curly grass family ; ferns of the flowering fern family ; ferns of the 



adder's-tongue family; fern photography; glossary; index. The analytical key 



based upon the stalks is an interesting piece of work and deserves to be tested 



by professional botanists in all parts of the country. The photographs of sori, 



most of which are taken at a magnification of 5i< diameters, are particularly 



excellent and will be valuable not only to the beginner who is learning to identify 



ferns, but also to the teacher who will find them excellent for demonstration. 



The book is intended to cover the same territory as Gray's " Manual," all the 



ferns being described and illustrated. 



The detailed directions for photographing ferns can hardly be condensed to 

 he limits of a review. It can only be mentioned that in photographing sori, at 

 camera with a bellows extension of twenty-four inches was used, and that the 

 focal length of the regular lens was reduced by slipping on over it a cheap 

 " copying and enlarging" lens, thus giving a magnification of about 5^^ diam- 

 eters. 



While the book is addressed to amateurs and is written in popular style, the 

 author's extensive knowledge of ferns in the field together with the peculiar key 

 and excellent illustrations — all of which are original — will make it useful to the 

 experienced botanist. c. j. c.

ture of the subject is organized and 



presented, but the work is not a mere compilation, since it embodies the views 

 and results gained by the authors in years of investigation in this line. It is 

 hoped that the book will be useful to those who desire a more intimate knowledge 

 of the morphology of the higher plants, and especially useful to those engaged in 

 research. The titles of the chapters are as follows : Introductory, the flower, 

 the microsporangium, the megasporangium, the female gametophyte, the male 

 gametophyte, fertilization, the endosperm, the embryo, classification, geographic 

 distribution of Angiosperms, fossil Angiosperms, phylogeny of Angiosperms, 

 comparative anatomy of the Gymnosperms and Pteridophytes, comparative anat- 

 omy of Angiosperms. The last two chapters were written by Prof. Jeffrey of 

 Harvard. c. j. c.
