AGKICULTURAL CHEMISTRY— AGROTECHNY. 



Treatise on general and industrial inorganic chemistry, E. Molinari, trans. 

 by E. Feilmann {Philadelphia, 1012, 3. ed., rev. and enl., pp. XVI-\-704, pis. 3, 

 figs. 280). — The first part of this thh'd edition deals with general chemistry, 

 the second with the nonmetals, and the third with metals, with an appendix 

 which deals with the treatment of water for industrial purposes. The boolc is 

 plentifully illustrated with cuts and drawings, and discusses many subjects, 

 such as the fixation of atmospheric nitrogen, of interest to the agricultural 

 chemist. 



General and industrial organic chemistry, E. Molinari, trans, by T. II. Pope 

 {Philadelphia, 1913, 2. cd., rev. and enl., pp. XIX +770, figs. 506).— X number of 

 alterations have been made in this English edition, consisting chiefly in ampli- 

 fications of the statistical data referring to Great Britain and the United States. 

 The first part of the book deals with the general chemistry of organic com- 

 pounds, while the second portion considers the derivatives of methan and includes 

 the chemotechnical processes concerned in the petroleum industry, the manufac- 

 ture of alcohol and alcoholic beverages, the preparation of waxes, soap, and 

 sugar, the tartar industry, animal oils and fats, etc. The products belonging to 

 the cyclic compounds are also given consideration. 



Allen's commercial organic analysis, edited by II. Leffmann, W. A. Davis, 

 and S. S. Sadtler {Philadelphia, 4. ed., vols. 2, 1910, pp. X-\-o20, figs. U; 3, 

 1910, pp. X-\-635, figs. 25; 4, 1911, pp. VIII+466, figs. 7; 5, 1911, pp. IX-\-704, 

 figs. 8; 7, 1913, pp. IX-\-563, figs. 29; 8, 1913, pp. X+696, figs. 60).— This is a 

 new edition of this well-known work, the first and sixth volumes of which have 

 been previously noted (E. S. R., 22, p. 508; 27, p. 806). The topics dealt with 

 are as follows: Volume 2, fixed oils, fats and waxes, soap, glycerol, wool fat; 

 volume 3, hydrocarbons, asphalt, phenols, aromatic acids, modern explosives; 

 volume 4, resins, rubber, gutta-percha, essential oils; volume 5, tannins, dyes 

 and coloring matters, inks; volume 7, alkaloids, animal bases and acids, gluco- 

 sids, cj-anogen ; and volume 8, enzyms, proteins, milk, meat, hemoglobin, pro- 

 teoids, fibroids. 



Practical agricultural chemistry, S. J. M. Auld and D. R. Edwardes-Ker 

 (London, 1913, pp. XXIV +243, pis. 5, figs. 28).— This book is intended, accord- 

 ing to the preface, as an aid to those students working through courses of 

 instruction for the purpose of obtaining the bachelor of science degree of the 

 University of London, Quantitative analytical methods are introduced through- 

 out the work, largely as a means of intei^preting principles or expressing ideas 

 and not as an end in themselves. In the work prescribed a knowledge of the 

 more common qualitative and quantitative processes of general chemistry is 

 taken for granted.
