devoted to "Structural Botany;" it contains many additions not found in 

 former editions — notably, the chapter on the "Adaptations of the Flower to 

 the Act of Fertilization." 



The second volume, by Professor Goodale, is also a complete botanical 

 work in itself, but treats specially of the Microscopic Structure, Development, 

 and Functions of Phsenogamous plants, their Physiology being treated in a 

 most efficient manner. Vols. III. and IV. are in preparation. The series v/ill 

 prove invaluable to the advanced botanical student. 



Handbook of Mosses, with an account of their Structure, 



Classification, Geographical Distribution, and Habitats. By James E. Bagnall, 

 A.L.S., Vice-Pres. of the Birmingham Natural History and Microscopical 

 Society, Post Svo, pp. vii. — 96. (London : Swan Sonnenschein and Co. 

 1886.) Price IS. 



A very handy and useful book for the young collector, nicely illustrated 

 with about 40 engravings. We cordially endorse the words of the author when 

 he says : — "Study Mosses; no objects are more readily found. And if you 

 desire a study which will present you with a constant supply of interesting 

 objects — whether you take the varieties of leaf form, or notice the elegant 

 designs of the little capsules ; . . . .if you desire a study which will tind 

 you employment the whole year round, let me advise you to study Mosses." 



A Course of Practical Instructions in Botany. By F. 



O. Bower, M.A., F.L.S., and Sydney H. Vines, M.A., D.Sc, F.L.S. With 

 a Preface by W. T. Thiselton Dyer, M.A., C.M.C, F.R.S., F.L.S. Part I., 

 Phanerogamse — Pteridophyta. Crown 8vo, pp. xi. — 226. (London : Mac- 

 millan and Co. 1885.) Price 6s. 



A valuable work for the practical botanist, dealing entirely with the prepa- 

 ration of the different tissues of plants and their examination under the micro- 

 scope. A list of the various staining media and chemical re-agents, with 

 directions for cutting and mounting sections ; followed by a study of the 

 Phanerogamge and Pteridophyta, in which the tissues and organs are carefully 

 and accurately described, with practical directions for their microscopical 

 examination. It also explains how to cultivate the Pteridophyta from the 

 spores. We can highly recommend this book. 



An Introduction to Practical Bacteriology, based upon 



the methods of Koch. By Edgar M. Crookshank, M.B.Lond., F.R.M.S., 

 etc.. Demonstrator of Physiology, King's Coll., London. (London: H. K. 

 Lewis. 1886.) 8vo, pp. xxii. — 249. Price 14s. 



This valuable work, which embodies the notes made by the author in 

 various laboratories, is intended to help the student beginning the study of 

 Bacteriology. The methods of pure cultivation of the Bacteria are very con- 

 cisely given. In Part I. we have a description of Apparatus, Materials, and 

 Re-agents employed in a Bacteriological Laboratory ; Microscopical Examina- 

 tion of Bacteria in Liquids ; Cultivations on Solid Media and in Tissues ; 

 Preparation and Staining of Tissue Sections ; Preparation of Nutrient Media 

 and Methods of Cultivation ; Experiments upon the Living Animal ; Examina- 

 tion of Animals Experimented upon ; and the Methods of Isolating Micro- 

 organisms from the Living and Dead subject. Part 11. is systematic and 

 descriptive, with special microscopical methods. The work is illustrated with 

 30 plates (many of them are beautifully coloured), and 42 wood engravings.
