Traite de Zoologie Concrete. Par Yves Delage and 

 Edoard Herouard. Tome I., La Cellule et Les Protozoaires. Royal 8vo, 

 pp. XXX.— 584. (Paris : Librairie, C. Reinwald. 1897.) Price 25 francs. 



The authors have entitled this work Concrete Zoology in contradistinction 

 to those works which are concerned more generally with abstract theories. 



After an elaborate account of the structure of the cell, the Protozoa are 

 described with great minuteness and care. The volume is illustrated by 870 

 very beautiful figures in the text, the majority of which are printed in colours. 



We find also a Table of the Classification of the Protozoa ; a Classified 

 Bibliography of— I, The Cell ; 2, Protozoa in general ; 3, Rhizopods ; 4, Spo- 

 rozoa ; 5, Flagelles ; and 6, Cells ; an Index of Technical Terms ; and a 

 General Index of the Protozoa. 



Plants EuropvE^.. Tomus II., Fasc. i. Edited by Dr. 

 M. Giirke. 8vo, pp. 160. (Leipzic : Wilhelm Engelmann. London : Wil- 

 liams and Norgate. 1897.) 



Volume I. of this most useful work appeared seven years ago, but the 

 death of Dr. Richter, the then editor, rendered it very doubtful if this list of 

 European Plants would ever be completed. Dr. Giirke has, however, under- 

 taken to continue the work, which will be issued in parts at frequent intervals. 



The name of every plant is followed by a reference to the work in which it 

 is described, synonyms are given, and mention is made of the countries in 

 which the plants are found. 



Open-Air Studies in Botany : Sketches of British Wild 

 Flowers in their Homes. By R. Lloyd Praeger, B.A., B.E., M.R.I. A. 

 Illustrated by Drawings from Nature by S. Rosamond Praeger, and Photo- 

 graphs from Nature by R. Welch. 8vo, pp. xiii. — 266. (London: C. Griffin 

 and Co. 1897.) Price 7/6, plain; 8/6, gilt top. 



The chapters in this specially interesting book exhibit, by means of fami- 

 liar scenes in our own islands, glimpses of plant-life interpreted by the study of 

 actual scenes from nature ; for, as the author says, " thus only can we hope to 

 comprehend the life of a plant or of a plant-community, and appreciate the 

 conditions under which each species lives, and the adaptations by which each is 

 able to maintain its position in the plant- world and fulfil its proper functions. 

 There are 6 plates and 68 illustrations in the text. 



Among the Wild Flowers. By Rev. Henry Wood. Vol. I., 

 Spring; Vol. II., Summer. Cr. 8vo, pp. 250. (London : Swan, Sonnenschein, 

 and Co. 1897.) Price i/- each. 



The aim of the author of these two vols, of the "Young Collector" 

 series has been to give simple but accurate information respecting the principal 

 Natural Orders and Genera of our British Flora ; the method adopted being to 

 describe plants which were in bloom at the time, and to notice with these 

 other species and genera of the same Natural Order. There are a number of 

 good illustrations.
