PREFACE.
A portion of the following pages originally appeared In
the columns of the American Chemist, under the title:
^'Schemes of Analyses execrtted in the School of Mines,
Cohimbia College." Numerous applications for copies in
book form have induced the author to publish the Schemes
under a more general title.
Since writing the articles the author has been called to
another sphere of labor, and the circumstances which led
to their compilation are explained in the following para-
graphs, quoted from the prefatory remarks accompanying
the original publication.
" The system of instruction in Quantitative Analytical
Chemistry, organized in the School of Mines, Columbia
College, by Dr. C. F. Chandler, has been developed by the
Assistants, who have had charge of the Laboratory for
Quantitative Analysis, Mr. Alexis A. Julien, Dr. Paul
Schweitzer, and the writer.
The practical examples and the methods of analysis were
originally selected by Prof. Chandler; the latter have been
modified by the Assistants, and from time to time they
have introduced new processes, conforming to the advances
made in this department of chemical science.
