Hitherto, no work suitable for general nse, treating of all these subjects
within the limits of a single volume, could be found; consequently the atten
tion thcy have received has not been at all proportionate to their importance.
It is believed that a book containing so mnch valuable information within so
small a compass, cannot fail to meet with a ready sale among all intelligent
persons, while Professional men, Physicians, Medical Students, Photograph-
ers, Telegraphers, Engineers, and Artisans generally, will find it specially
valuable, if not nearly indispensable, as a book of reference.
“ We strongly recommend this able treatise to our readers as the first
work ever published on the subject frse from perplexing technicalities. In
style it is pure, in deseription graphic, and its typographical appearance is
artistic. It is altogether a most excellent work.”—Rclectic Äfedical Journal.
“ It treats fully of Photography, Telegraphy, Steam Engines, and the
various applications of Electricity. In short, it is a carefully prepared
volume, abreast with the latest scientific discoveries and inventions. ’—Uartr
f/>rd Courant.
Plympton’s Blow-Pipe Analysis.
12mo. Cloth. $150.
THE BLOW-PIPE : A Guide to Its Use in the Determination
of Salts and Minerals. Compiled from various sources, by
George W. Plymptoit, C.E., A.M., Professor of Physical
Science in the Polytechnic Institute, Brooklyn, IST. Y.
“ This manual probably has no superior in the English language as a text-
book for beginners, or as a guide to the Student working without a teacher.
To the latter many illustrations of the Utensils and apparatus required in
using the blow-pipe, as well as the fully illustrated deseription of the blow-
pipe Haine, will be especially serviceable.’’—New York Teacher.
