=Zoogeography.= By F. E. Beddard, M.A., F.R.S. With Maps. 6_s._ _Daily Chronicle._ Although included in the series of Cambridge Natural Science Manuals, and therefore designed chiefly for students of biology, Mr Beddard deals with his subject in a clear and graphic way that should commend his book to the general reader interested in the question. His style, while never lacking dignity, avoids the dulness which too often accompanies that virtue. =Elementary Palæontology--Invertebrate.= By Henry Woods, M.A., F.G.S. With Illustrations. Crown 8vo. Second Edition. 6_s._ _Nature._ As an introduction to the study of palæontology Mr Woods's book is worthy of high praise. =Outlines of Vertebrate Palæontology= for the use of Students of Zoology. By A. S. Woodward, Assistant Keeper in the Department of Geology in the British Museum. Demy 8vo. 14_s._ _Athenæum._ Mr Woodward, in studying vertebrate fossils for the purpose of this volume, takes the biological view, and has designed his work primarily for the assistance of students of vertebrate morphology and zoology. Mindful, however, of the geological side of the subject, he has introduced a chapter on the succession of the vertebrate faunas, offering a brief but convenient summary of the distribution of vertebrate life throughout geologic time. The author is to be congratulated on having produced a work of exceptional value, dealing with a difficult subject in a thoroughly sound manner. =The Vertebrate Skeleton.= By S. H. Reynolds, M.A., Trinity College. Crown 8vo. 12_s._ 6_d._ _British Medical Journal._ A volume which will certainly take its place amongst the standard text-books of the day. BIOLOGICAL SERIES. =Practical Morbid Anatomy.= By H. D. Rolleston, M.D., F.R.C.P., Fellow of St John's College, Cambridge, Assistant Physician and Lecturer on Pathology, St George's Hospital, London, and A. A. Kanthack, M.D., M.R.C.P., Lecturer on Pathology, St Bartholomew's Hospital, London. Crown 8vo. 6_s._ _British Medical Journal._ This manual can in every sense be most highly recommended, and it should supply what has hitherto been a real want. =The Soluble Ferments and Fermentation.= By J. Reynolds Green, Sc.D., F.R.S., Professor of Botany to the Pharmaceutical Society of Great Britain. Demy 8vo. 12_s._ _Nature._ It is not necessary to recommend the perusal of the book, to all interested in the subject since it is indispensable to them, and we will merely conclude by congratulating the Cambridge University Press on having added to their admirable series of Natural Science Manuals an eminently successful work on so important and difficult a theme, and the author on having written a treatise cleverly conceived, industriously and ably worked out, and on the whole, well written.
