A Treatise on the British Freshwater Algae. By 



G. S. WEST, M.A., A.R.C.S., F.L.S., Lecturer in Botany in the 



University of Birmingham. Demy 8vo. IQS. 6d. net. 



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



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



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



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.

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 horticulture 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. 



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

 thoroughly business-like volume, lucid though compact.
