ELEMENTARY APPLIED CHEMISTRY 



By LEWIS B. ALLYN, State Normal School, Westfield, Mass. 



, cloth, 127 pages, illustrated, 60 cents 



THIS book offers practical applications of chemistry to pres- 

 ent-day civic and industrial problems. The course is essentially 

 that conducted by the author in the Westfield State Normal 

 School, where a pure-food campaign has been made one of the 

 objects of the course. The widespread results shown in the 

 almost complete elimination of the sale of impure foods in 

 the city of Westfield are matters of national knowledge. 



Besides the work with food products, the book includes 

 exercises with water, textile fabrics, drugs, soils, and similar 

 materials. It gives a particularly complete analysis of each 

 subject and brings out clearly the practical relation which 

 chemistry bears to everyday matters. The order of presen- 

 tation differs radically from that of the usual textbook in 

 chemistry, the common elements, bases, and radicals being 

 taken up as they naturally occur. 



For supplementary use with any regular textbook " Elemen- 

 tary Applied Chemistry " is invaluable. Teachers of domestic 

 science will find the chapter on food values most important, 

 while for- boards of health, inspectors of milk, and all those inter- 

 ested in the pure-food problem, the book has a special function 

 in its valuable information and tests relating to their work.
