^04 REVIEWS. 



This book, the first part only of Vol. 11. of Prof. Asa Gray's series of 

 Botanical Text- Books, is a valuable and interesting one to the advanced student 

 of Botany. Professor Goodale strongly insists upon the use of the Microscope 

 in botanical research, and gives many simple and clear directions for its use, 

 and for the preparation of the different tissues of plants for examination. The 

 minute structure and development of every part of the plant is clearly 

 explained, and well illustrated by no fewer than 141 capital engravings. 



The second part of this volume will deal with Vegetable Physiology, and 

 will be puljlished very shortly ; it will then form a volume that no earnest 

 botanical student should be without. 



The Microtomists Vade-Mecum. A Handbook of the 



Methods of Microscopic Anatomy. By Arthur Bolles Lee ; pp. XIV. — 424. 

 (London : J. and A, Churchill, 1885.) 



The aim of the Author of this useful work is to put into the hands of the 

 anatomist a concise, but complete account of all the methods of preparation 

 that have been recommended to the Microscopic Anatomist. We have first an 

 Introductory Chapter, with general instructions for preparing objects for 

 examination ; followed by chapters on Fixing Agents, Theory of Staining, 

 Hardening Agents, Theory of Embedding, with a word on Microtomes, etc. 

 etc. Both the Amateur and the Advanced Anotomist will find much valuable 

 information in this book. 



Histological Notes for the use of Medical Students. By 



W. Horscraft Walters, M.A., Demonstrator and Assistant Lecturer in 

 Physiology at the Owen's College, Manchester ; pp. VI. — 65. (Manchester : 

 J. E. Cornish ; London : vSmith, Elder, and Co., 1884.) 



A well written and unpretentious little volume. The instructions given 

 are an enlargement, although still in a very condensed form, of the Author's 

 " sheets " given to the students of the Practical Histology Class at the College. 

 They are very plainly and concisely written, and will doubtless be found of 

 great assistance to the Histological student. 



A Manual of Photography, intended as a Text-Book for 



Beginners, and a book of reference for Advanced Photographers. By M. 

 Carey Lea. Second edition, revised and enlarged ; pp. 439, 8.4. (P'hiladel- 

 phia, U.S.A. : Printed for the Author.) 



The work before us is one of the best Photographic Manuals which we 

 have seen, and one that every practical Photographer would do well to study. 

 It is divided into four portions ; the first gives a short and clear course of 

 instruction for beginners. In the subsequent parts the various subjects are 

 treated of in detail, e.g. : Part 11, treats of Photographic Optics and the 

 Theory of Perspective ; Part III. — Photographic Manipulations ; Part IV. — 

 Certain Theoretical Considerations as to the Action of Light on Chemical 

 Compounds, and the Action of various portions of the .Spectrum ; Part V, is 

 devoted to Photography in its Relation to Health, and also to Chemical 

 Manipulation. 



La Photographie Appliquee a l'Histoire Naturelle. 



Par M. Trutat ; pp. XIII.— 223. (Paris : Gauthier-Villars, 1884.) 



We have here very full and carefully written instructions for the produc- 

 tion of Photographs in every department of Natural History, Zoology, Botany,
