Excerpt from An Introduction to Qualitative Chemical Analysis This manual is designed to impart but little chemical truth directly. It aims rather to lead the student to gain that truth himself as nearly as possible at first hand and as a product of his own thinking. This he is enabled to do, without waste of time, guided as he is by the suggestions of the book and the constant prevision of the live teacher. The student is first thoroughly grounded in the fundamental ideas of chemistry before he goes on to use those ideas as tools in the practical work of qualitative analysis. If he gains a proper conception of the relation of the atom to the molecule, of valence; if he masters the principles of nomenclature and the chemical equation as set forth in chapters ii. and iii., he will certainly acquire his chemistry with facility and clearness. That it produces strong, accurate, enthusiastic, and independent students the author has demonstrated in his own classes through several years. For the sake of emphasizing what is expressed elsewhere, the author would insist upon regular recitations, at stated times, upon the laboratory work, in which there shall be full and searching discussion of the results obtained, of errors committed, how these errors have arisen and how controlled. Comparison of results obtained and informal discussion of the difficulties to be met with beget an interest and enthusiasm for the work which is invaluable. Moreover, a few experiments fully reported and discussed are of much greater value than many experiments with little time given to such discussion.
