Text-Book of Biology. By H. G. Wells, B.Sc.Lond., F.Z.S. 

 With an Introduction by G. B. Howes, F.L.S., F.Z.S. Part I., Vertebrata. 

 Cr. 8vo, pp. X. — 149. (London : W. B. Clive and Co. 1892.) Price 6s. 6d. 



This little book — which is one of the Univ. Corr. Coll. Tutorial Series — 

 contains in a concise form a large amount of useful information, the subjects 

 treated being the Rabbit, Frog, Dog-Fish, and Amphioxus, followed by a 

 chapter on Development, Miscellaneous Questions, etc. We are disappointed 

 with the plates which are diagrammatic, the reference-letters being very indis- 

 tinct. The student, however, will find the book helpful. 



The Building of the British Isles : A Study in Geological 

 Evolution. By A. J. Jukes- Browne, B.A., F.G.S., etc. Second edition, 

 revised. Cr. 8vo, pp. xii. — 465. (London : George Bell and Sons. 1892.) 

 Price 7s. 6d. 



The aim of the book before us is the restoration of the physical and geo- 

 graphical conditions which prevailed in the British area during each of the great 

 periods of time which make up our geological sequence, the author's chief 

 object being to trace out the succession of physical and geographical changes 

 which have led up to the existing disposition of land and water in the north- 

 western portion of Europe. There are 15 plates, chiefly diagrammatic. 



Elementary Mathematical Astronomy, with Examples and 

 Examination Papers. By C. W. C. Barlow, M.A., B.Sc, and G. H. Bryan, 

 M.A. Cr. 8vo, pp. vi. — 442. (London: Clive & Co. 1893.) Price 6s. 6d. 



In the book before us— which is now in its second edition — the aim of the 

 authors has been to produce a book that shall take its stand between the popu- 

 lar and non-mathematical treatises, and those which involve high mathematics, 

 and to prove a suitable text-book for such examinations as those for B.A. and 

 B.Sc. of the University of London. The diagrams are clear and good. 



Zoology for Secondary Schools. By C. de Montmahon 

 and H. Beauregard ; translated by Wm. H. Greene, M.D. Cr. 8vo, pp. 368. 

 (Philadelphia: J. B. Lippincott and Co. 1893.) 



This book forms the basis of instruction upon the natural history of animals 

 in the secondary schools of France, and treats the subject in a manner found by 

 experience to excite most interest on the part of the pupil. The illustrations, 

 319 in number, form an important feature of the work, and are the best of the 

 kind we have seen. 



Handbook of Practical Botany. By E. Strasburger, edited 

 from the German by W. Hillhouse, M.A., F.L.S., etc. Third edition. 8vo, 

 pp. xxiv. — 425. (London: Swan Sonnenschein and Co. 1893.) Price 9s. 



A very desirable work for the microscopical botanist and all those who wish 

 to become acquainted with the elements of scientific structural botany. It is 

 divided into thirty chapters, leading the student on by easy stages. The first 

 assumes on the part of the worker entire ignorance as to the use of his instru- 

 ments. In the appendices are given an alphabetical list of plants used for 

 study ; an alphabetical list of reagents, and how to prepare and use them ; and 

 Notes on Methods and Selected Reagents. There are upwards of lOO very 

 clear and good illustrations.
