Science by the publication of this text-book. It contains the methods adopted 

 in the Cavendish Laboratory for the practical determination of problems 

 relating to the principal Physical Sciences, together with a description of the 

 more important instruments used. It embraces practical work in Linear and 

 Map Measurement, Mechanics, Acoustics, Heat, Light, and Electricity; the 

 information imparted being quite distinct from that found in ordinary text- 

 books. 



Aids to the Analysis of Food and Drugs. By H. 



Aubrey Husband, M.B., CM., B.Sc, M.R.C.S., F.R.C.S. Edin. ; pp. 77. 

 (London: Bailliere, Tindall, and Cox.) 



We are told by the Author of this little pamphlet that it is especially 

 intended for the assistance of candidates for sanitary degrees. We must 

 confess that we doubt the utility of a small volume of this kind. If it be 

 intended to teach analytical chemistry, we fear it will fail in its object, as in 

 consequence of the condensed nature of the instructions given, the minute 

 details essential to a correct result being insured are necessarily omitted. 



The Microscope in Botany. A guide for the Microscopical 



Investigation of Vegetable vSubstances. From the German of Dr. Julius 

 Wilhelm Behrens. Translated and Edited by Rev. A. B. Harvey, A.M., 

 assisted by R. H. Ward, M.D,, F.R. M.S. Illustrated with thirteen plates 

 and fifty-three woodcuts; pp. XV. — 466. (Boston, U.S.A. : S. E. Cassino 

 and Co., 1885.) 



The very valuable work before us has engaged the constant attention of 

 the Author since 1880. Chapters I. and II. treat of the Microscope and its 

 Accessories, and chapter III. of the Preparation of Microscopic Objects ; 

 chapter IV. of Reagents ; chapter V. of Microscopical Investigation of 

 Vegetable Substances. In the compilation of this work the author has 

 attempted the utmost completeness. It deals with the anatomical constitution 

 of the cell and of plant tissue, and yet its enquiries relate far more to physio- 

 logical and biological processes and results, rather than to matters purely 

 anatomical and histological. 



The treatise occupies a field almost entirely to itself in the botanical 

 literature both of Germany and of the English-speaking world, and we trust 

 that its publication will stimulate investigations into the deeper problems of 

 plant-life. The American Editors have introduced some very valuable 

 additions into the text ; these are enclosed in brackets, and marked with the 

 initials of the respective editor. We consider this the most valuable work of 

 the kind that has come under our notice. It is beautifully printed on very 

 superior paper. 



The Preparation and Mounting of Microscopic Objects. 



By Thomas Davies, Edited by John Matthews, M.D., F.R.M.S. ; pp. VIII.— 

 214. (London : W. PI. Allen and Co.) 



This useful little book, now in its fourteenth thousand, is too well known 

 to need any description from us. 



Physiological Botany. Part I. Outlines of the Histology 



of Pha;nogamous Plants. By George Lincoln Goodale, A.M., M.D., Professor 

 of Botany in Ilavard University ; pp. VII. — 194. (New York : Ivison, 

 Blakeman, Taylor, and Co., 1885.)
