An Introduction to Nature Study. By Ernest Stenhousc, B.Sc. 

 London : Macmillan & Co. Trice 5s. 



" One of the most encouraging of recent educational movements is 

 the increasing importance attached, both in this country and abroad, 

 to what is called Nature Study. . . . The aim of Nature Study ... is 

 not primarily the acquisition of the facts of natural history ; it is rather 

 a training in the methods of open-eyed, close, and accurate observation, 

 e ipecially of familiar animals and plants, which shall teach the Student 

 to sir what he looks at, and to think about what he sees." 



This book has been written in the spirit of the above sentences 

 quoted from the preface. Part I. deals with Plant Life — seeds, how a 

 green plant feeds, the forms and duties of leavi s, buds and twigs, how 

 stems do their work, some common dowers, grasses, common forest 

 trees, fruits and seed dissemination, ferns and horsetails, and, lastly, 

 mosses, mushrooms, and moulds. Part II. takes up Animal Life. The 

 subjects include a sketch of the rabbit as a typical mammal, how a 

 rabbit lives, some other mammals (as the cat, dog, and sheep), the 

 pigeon as a typical bird, the development and education of the chick, 

 some familiar British birds, frogs and tadpoles, the habits and life- 

 histories of common insects, some crustaceans, mollusca, and worms ; 

 and, finally, a chapter on Field-Work, with a monthly nature 

 calendar. 



The book is a valuable one from its own standpoint, and one which 

 we recommend to those engaged in nature-study work. The short 

 chapter on Field-Work is excellent, and if we had space we would quote 

 it in extenso. We can, however, only advise our readers to take Mr. 

 Stenhouse's advice, and make a large map of the district they work 

 in, and record upon this the positions of all features of special local 

 interest, duplicating the map for flowers, trees, animals, archaeology, 

 geology, and so forth. The idea is a capital one, and the result could 

 not fail to be instructive and useful. 



A Treatise on Zoology. Edited by E. Ray Lancaster, F.R.S. 



Part I. Introduction and Protozoa. London : A. & C. Black. 



Price 15s. net. 

 This admirable volume comes at a time which is opportune for 

 many of our readers whose attention has been drawn to the Protozoa 

 by Mr. Forrest's articles on this group in our series on "British Field 

 Zoology." Those articles have had the effect of determining some 

 field naturalists to take up this part of zoology as a study, and they 

 now want a text-book which will take them much farther than it is the 

 object of this Journal to do. To these readers, and to others who are 

 already interested in the Protozoa, this book will be a great boon, and 

 we advise them to become possessed of it. 



This Part I. is written by Professors J. B. Farmer, E. A. Minchin, 

 S. J. Hickson, and Mr. J.J. Lister, and the mere enunciation of these 

 names is sufficient to guarantee the excellency of the matter. Each of 

 them has written on his special subject, Dr. Lister on the Foraminifera,
