234 THE MICROSCOPE. 



Jg^etfiCXtJS, 



A Text-Book of Botany. By Julius Sachs, Professor of Botany in the Uni- 

 versity of Wiirzburg. With an Appendix by Sidney H. Vines, M. A., D. 

 Sc, F. L. S. Fellow and Lecturer of Christ's College, Cambridge. Second 

 edition. Pp. 980. 4.92 figures. MacMillan & Co., 112 Fourth Avenue, 

 New York. 1883. 



A new edition of this standard work will be warmly welcomed 

 by American botanists, for there is no other book its equal in its 

 own field. In fact, as a text-book of botany it stands preeminently 

 ahead, no other work even approaching it in its completeness. 



The first few pages have been entirely rewritten, and, that Book 

 I. might be more complete, an appendix has been added of twenty 

 pages. This appendix forms a valuable addition to the work. The 

 index covers eighteen three-columned pages, thus enabling the 

 reader to refer to any subject quickly and accurately. 



The illustrations have ever been a prominent feature of the 

 work. Nearly every one is original and the direct result of labori- 

 ous investigation. The engraving is done in the highest style of 

 the art. Before us then is a full, complete text-book of botany. It 

 is so complete, so superior, that words of faint praise detract from 

 rather than add to its true worth. To the botanist it is indispensa- 

 ble, and to the microscopist supremely valuable. 



A Manual of Chemical Analysis, as Applied to the Examination of Med- 

 icinal Chemicals. Third edition. Thoroughly revised and enlarged. By 

 Frederick Hoffmann, A. M., Ph. D., Public Analyst to the State of New 

 York; and Frederick B. Power, Ph. D., Professor of Analytical Chemistry 

 in the Philadelphia College of Pharmacy. Henry C. Lea's Son & Co. ■ 

 Philadelphia. 1883. Pp. 624. Figures 180. 



This work has been before the professions of medicine and 

 pharmacy so long that its true value and place can be easily 

 ascertained. It is certainly a safe guide for the detection of impuri- 

 ties and adulterations. The identity and quality of medicines and 

 of the substances used in their preparation are carefully considered. 



The illustrations of various crystals are very beautiful and, so 

 far as we have examined, very accurate. 



The present edition contains much new and original matter, 

 until now the work contains all the most approved methods for the 

 separation, identification and quantitative estimation of those chem- 

 ical poisons likely to be met with in forensic medicine. It is a "guide 

 to the quality and purity of the medical chemicals of commerce.
