+A Treatise on the British Freshwater Algæ.+ By G. S. WEST, M.A., A.R.C.S., F.L.S., Lecturer in Botany in the University of Birmingham. Demy 8vo. With a frontispiece and 166 illustrations. 10_s._ 6_d._ _net_. _Nature._ Its aim is stated as “to give the student a concise account of the structure, habits and life-histories of Freshwater Algæ, and also to enable him to place within the prescribed limits of a genus any Algæ 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., Sc.D., Director of the Royal Botanic Gardens, Ceylon. _Third edition._ Crown 8vo. 10_s._ 6_d._ _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. _Athenæum._ The whole is well abreast of modern research, and a thoroughly business-like volume, lucid though compact. +Agriculture in the Tropics.+ An elementary Treatise. By J. C. WILLIS, M.A., Sc.D. Demy 8vo. With 25 plates. 7_s._ 6_d. net_. +Palæontology--Invertebrate.+ By HENRY WOODS, M.A., F.G.S., University Lecturer in Palæozoology. _Fourth edition._ Crown 8vo. With 151 illustrations. 6_s._ +Outlines of Vertebrate Palæontology for students of Zoology.+ By ARTHUR SMITH WOODWARD, M.A., F.R.S., Keeper of the Department of Geology in the British Museum. Demy 8vo. With 228 illustrations. 14_s._ _Athenæum._ The author is to be congratulated on having produced a work of exceptional value, dealing with a difficult subject in a thoroughly sound manner.
