SCIENCE- AD VERTISEMENTS 



The Chemistry 

 of Everyday Things 



as taught in IVeed's Chemistry in the 

 Home, not only provides training in 

 scientific thinking, but gives the pupil 

 much valuable practical information. 



The book is intended for early use in the 

 high school by pupils who are not preparing 

 for college. Instead of devoting considerable 

 time to chemical theory this book is essen- 

 tially practical. Metals, Baking Powders, 

 Soaps, Foods, Textiles, Chemistry of Cook- 

 ing, Dyes and Dyeing suggest the usefulness 

 of this course.

For Students of 

 Analytical Chemistry 



Logarithmic Reduction Tables 



By CHARLES J. MOORE, Austin Teaching 

 Fellow in Advanced Analytical Chemistry, 

 Harvard University. 



Accurate tables covering gravimetric, 

 volumetric, and gas analysis. To famil- 

 iarize the student with logarithms as a 

 short cut to the solution of arithmetical 

 problems, the method of using each table 

 is fully explained. The material is ar- 

 ranged conveniently for the experienced 

 chemist, who will find the well-known ex- 

 planations so placed that they do not 

 interfere with a rapid use of the tables.
