In a popular form the author gives an excellent resume of 

 the facts and theories in regard to the transformation of parts and 

 the abnormalities of structure occurring in nature and induced 

 bv cultivation.

(8vo., pp. ix -|- 253, Boston, Ginn & Co., 1890). 



This little book is a welcome addition to our available mate- 

 rial for teaching the general principles of Botany. It consists of 

 chapters on the structure of cells and tissues, followed immedi- 

 ately by others on the classification of plants, the primary sub- 

 divisions recognized being { 1 ) Protophytes, including Slime 

 Moulds, Schizophytes and Volvocinc:e; (2) Alg;e, grouped un- 

 der the Green, the Brown and the Red; (3) Fungi, including as 



K 



classes, riiycomycctes, UstillaginecX, Ascomycetes and Basidio- 

 mycctes; (4) Bryophytes ; (5) Pteridophytes and (6) Sperma* 

 phytes (why not Spermatophytes ?) Under this last group we 

 note one of the most valuable features of the book, viz., the de- 

 parture from the generally accepted arrangement of the angio- 

 spcrms, and the substitution therefor of modern ideas of classi- 

 fication. The difficulty in the use of the system here adopted 

 will be in the lack of floras arranged on a similar plan. Chapters 

 are devoted to the fertihzation of flowers and to histological 

 methods. The book is illustrated by one hundred and twenty-, 

 eight cuts, nearly all of them new, exhibiting the structure of all 

 the larger groups, and they are among the most valuable ele- 



ments of the volume.
