Excerpt from The Elementary Principles of Chemistry
This book on elementary chemistry is based on the plan which, without essential modification, the writer has been following for thirteen years with his classes beginning the subject. Its inception was under the stimulating suggestion of the late Professor Josiah P. Cooke, of Harvard University, an early advocate of what has been called the quantitative method in teaching the subject even in elementary courses. The temerity of the writer in thus offering to his fellow-students and teachers the outcome of his personal experience is due to the hope, perhaps egotistic, that he may contribute, in howsoever small a measure, to making practicable and serviceable that which, he enthusiastically believes, is both scientifically and pedagogically an improvement on the older and still largely prevailing method.
In the preparation of the book two things have been assumed: first, that sufficient laboratory facilities are provided; and, second, that the teacher has information in the subject beyond that which the book itself supplies. The laboratory work by the student is made a large and essential part of the exposition, and it is generally assumed that he has performed the experiment illustrative of a topic before he gives attention to the fuller presentation of the same in the text.
