AGRICTTLTURAL CHEMISTRY— AGEOTECHNY. 



Chemistry of agriculture, C. W. Stoudart {Philadelphia: Lea and Febiger, 

 1913, pp. VI-j-364, pi. 1, figs. 83). — This hook on general agricultural chemistry 

 is intended as a brief treatise, particularly for students, but sufficiently elemen- 

 tary for general reference. The contents are as follows: The plant: Germi- 

 nation of the seed, growth of the plant, plant compounds, and crops; factors 

 in plant growth : The air, the soil-organic matter, the soil-inorganic matter, 

 fertilizers, lime, farm manure, soil and fertilizer analysis, insecticides and 

 fungicides, and the gas engine ; the animal : The chemistry of animal physi- 

 ology, food and digestion, and milk and dairy products. 



The farmer as a manufacturer, A. T. Stuart ( Canada Expt. Farms Bill. 20 

 {1914), ^- ^G''-> PP- IG). — ^An outline in popular language of some basic principles 

 in agricultural chemistry. That the farmer is the world's real manufacturer 

 of proteins, fats, carbohydrates, and fiber for making clothes is pointed out. 

 The object of the bulletin is to present in a similar manner some illustrations 

 of the chemical processes which take place in vegetable and animal life and to 

 show how the farmer, through the agency of his ci'ops and stock, uses the raw 

 materials supplied by nature for the manufacture of his finished products. 



Dairy chemistry: A practical handbook for dairy chemists and others 

 having control of dairies, H. D. Richmond {London: C. Griffin cC- Co., Ltd., 

 191-i, 2. rci\ ed., pp. XI -{-434, figs. 49). — The second edition of this work, the 

 fii-st of which was issued in 1907. It is stated that the obsolete portions of 

 the text have been eliminated and replaced by more recent matter. 



Analytical chemistry. — I, Qualitative analysis, II, Quantitative analysis, 

 F. P. Tke^vdwell {Analytischc Chcmic. Lcipsic: F. Dcutickc, I, QuaUtativc 

 Analyse, 1914, 8. ed. rev. and enl., pp. XII+522, pis. 3, figs. 25; II, Quantitative 

 Analyse, 1913, 6. ed. rev. and oil., pp. IX-\-134, pi. 1, figs. ,?S).— Revised and 

 enlarged editions of this well-known work. 



The germplasm as a stereochemic system, E. T. Reichert {Sci. Anicr. Sup., 

 78 {1914), Kos. 2023, pp. 226, 227; 2024, pp. 242, 2.}3).— The thesis of this paper 

 is that every individual is a chemical entity that differs in characteristic par- 

 ticulars from every other. The subject is discussed in the light of the author's 

 researches, previously noted (E. S. R., 31, p. 804). 



The constituents of the leaves and stems of Daviesia latifolia, F. B. Power 

 and A. H. Salway {Jour. Chem. Sac. [London], 105 {1914), No. 617, pp. 767- 

 778). — "The material employcMl for this investigation consisted of the leaves 

 and stems of D. latifolia (natural order Leguminosie), which had been specially
