46 NATURE-STUDY REVIEW [12:1— Jan., 1916 



Chemistry in the Home, Henry T. Weed, Manual Training 

 High School, Brooklyn, N. Y. 7 -+- 385 pages. 13.5 x 19 cm. 

 Cloth. 191 5. American Book Co. 



Chemistry books are written usually for advanced high school 

 students, but this text aims to meet the needs of those who elect 

 chemistry in the lower classes of their high school course. The 

 author has omitted much of the theory usually found in chemis- 

 tries, and has kept the language and the style of treatment simple 

 enough to suit younger minds. A large fund of information con- 

 cerning the chemistry of everyday things related to the home 

 and to industries is given in an interesting way. Each chapter 

 ends with helpful exercises and summaries. Formulas, equations 

 and valence are condensed into one chapter of fourteen pages. 

 The illustations and descriptions of processes, like salt making, 

 baking powders, oils, fats and soaps, textiles, dyes and dyeing, 

 sugars, starches, paper making, glass making, etc., are clear, 

 detailed and easily comprehensible to the young student. The 

 subject of foods, their preservation, relative cost and nutritive 

 value is treated in such a practical way that the student can apply 

 directly in the home the knowledge gained. Laundry chemistry 

 and the chemistry of cooking each receive a share of attention. 

 Such texts are in demand in present day teaching, for they awaken 

 the interest of boys and girls in the subject by a clear application 

 of principles to the home and community life.
