Nature. Its aim is stated as "to give the student a concise account 

 of the structure, habits and life-histories of Freshwater Alga, and also 

 to enable him to place within the prescribed limits of a genus any Algtt 

 he may find in the freshwater of the British Islands." To do this within 

 the limits of an octavo volume of less than 400 pages, in which are 

 numerous illustrations, is a task possible of accomplishment only by one 

 very familiar with the subject and skilled in concise expression ; but that 

 it has been successfully done will, we think, be the verdict after testing the 

 book thoroughly. ... Prof. West's treatment of his subject is instructive and 

 stimulating. 



A Manual and Dictionary of the Flowering Plants 



and Ferns. By J. C. Willis, M.A., Director of the Royal Botanic 



Gardens, Ceylon. Second Editioji. Complete in one volume. Crown 



8vo. io.f. 6d. 



Field. Taking this handy volume and a local flora, the traveller or 



student may do an enormous amount of practical field work without any 



other botanical literature whatever. ...The result is a work that ought to be 



included in every library of botany and horticultui-e or agriculture, and it is 



certainly one that the nomadic botanist cannot afford to leave at home.... 



We have used the original edition of this work since its publication, and 



have found it to be one of the most useful and comprehensive works on 



plants ever produced. 



Athenanim. The whole is well abreast of modern research, and a 

 thoroughly business-like volume, lucid though compact. 



Guardian. To all who wish to embark on original research it is most 

 suggestive of fruitful lines of investigation.
