Excerpt from Introduction to Chemistry
The success both of the German edition and the numerous translations of the author's Schule der Chemie was a very welcome confirmation of the utility of the educational principles which are emphasized in that book. On the other hand, on account of the conversational form in which the work was written, it is not well adapted for use as a textbook.
In the present instance the author has attempted to write a book which will be suitable to use as a text for beginning the study of chemistry, and yet it is based upon the same general principles as those adopted in the above-mentioned work. He has attempted to make it represent the sum of his wide experience in teaching.
The greatest difficulty to overcome lies in the very large amount of material available. Most elementary textbooks attempt to cover so much ground that a student frequently gets the idea that there is nothing more to learn, and this false impression interferes greatly with his further development. If a student actually gets such an impression, it must surely be because so many isolated facts have been showered upon him that he has had no time to learn how to analyze chemical phenomena thoughtfully. In this book, however, the author has tried to show from a few simple facts how it is possible, by carefully thinking over their causes and effects, to draw many wide and deep conclusions leading to new experiments and verifications, and he has thus sought to obtain, in elementary form, a practical introduction to scientific thought from chemical instruction. In this way the student does not get the impression that his knowledge of the subject is complete because he understands the book; but, rather, he will become more and more aware of the fact that far beyond the horizon which bounds his present view stretch fields that are open to him for further investigation.
