Excerpt from Hand-Book of Mineral Analysis
This collection of examples for practice in Chemical Analysis, is designed chiefly for the use of the laboratory. It is drawn up under the impression that it is easier for most minds to obtain a clear insight into general relations and laws by the study of special cases, than, inversely, to acquire a knowledge of individual cases by first directing the attention to general rules. An endeavour has been made to arrange the book in such a manner as still to leave enough to demand the reflection of the student and the explanations of the teacher; the latter also must point out the authority for the individual methods here given, if such information should at any time be required.
The Editor of the English Translation fully concurs with the views which have led the Author to the publication of this volume.
