Plant Analysis. Qualitative and Quantitative. By G. Dragen- 

 dorff, Ph. D., Professor of Pharmacy in the University of Dorpat, 

 Eussia. Translated by Henry G. Greenish. Published by J. H. 

 Vail & Co., New York. 1884. pp, 280. Price, $2.75. 



This work includes the detection and estimation of the 

 active principles of plants. It includes the micro- as well as 

 the macro-chemical analysis, and embraces all the widely dis- 

 tributed vegetable substances, as well as some of the rarer ones. 

 There is a full table giving the percentage composition of the 

 constituents of plants, and also a table giving the percentage of 

 carbon. The author states that the methods for plant analysis 

 are at present so complete that in point of accuracy they are 

 fully equal to those used for the determination of mineral con- 

 stituents. In fact, he says that " the analysis of a plant can 

 often be made more complete than that of a mineral." The 

 work is complete and exhaustive. 

 The Century. 



The February number of this interesting journal reaches 

 the enormous number of 180,000 for the first edition. The main 

 article that will excite the interest of the reader is by General 

 Grant, on " The battle of Shiloh." The illustrations for this 

 article are superb, and show the triumphs of wood-engraving. 

 It is doubtful if a more interesting number of a popular journal 

 was ever issued. In proof of this it is sufficient to say that 

 within a week after the appearance of this enormous first edi- 

 tion, it was all sold ; and a second edition of 20,000 copies has 

 just come from their press.
