Excerpt from ChemistryThe course given in this book is the result of experience. It should be completed in two years by a class (aged from 12 to 16 years) working for two hours per week.There is constant reiteration of fundamental facts and very little revision should be necessary if the examples are systematically set and exacted for home-work.The first chapter is intended for demonstration by the teacher. Much time Will be ultimately saved if it, is care fully explained.The Junior Chemistry papers of the Oxford and Cam bridge Examinations (especially those in Experimental Science), and of the College of Preceptors, the Board of Education and the Army Qualifying Examinations may be successfully taken after completing this course.The author is glad to record his gratitude to his colleague Mr W. R. Cooper for useful advice and assistance in reading through the proof-sheets. To his colleague Mr Lawrence Caldecott he would express his sincere thanks for preparing the examples and examination papers as well as for his untiring help and valuable suggestions.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
