SCIENCE-ADVERTISEMENTS 



The Chemistry 

 of Everyday Things 



as taught in Weed'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.
