HANDBOOK OF CHEMICAL TECHNOLOGY
By Rudolph Wagner, Professor of Technology
at the University of Wurtzburg. Translated,
with additions, by William Crookes, FRS
New York: D. Appleton & Co. The value oil
this book is attested by its great success, in
Europe, among those qualified to understand
how well Professor Wagner has done his work.
This translation is from the eighth German
edition, and the book has been translated into
French and some other languages. To those
who may need more complete definition of
terms, the character and aim of the work may
be suggested by the authors explanation:
MANS labor, considered from an economical
| point of view, is of a three-fod kind, being
| either productive, improving, or converting.
We distinguish likewise between the pro-
ductiOn obtained from the soil taken
in its widest sense, and between com
merce and manufacturing industry. The de-
partment Of labor, the object of which is to pre-
pare and render fit for use the raw materials
yielded by nature, is thai which, in a more
restricted sense, is called manufacturing indus
try, and the calculation of the methods by which
this object is attained, is called technology"
Technology is either mechanical or chemical,
although it is scarcely possible 10 draw a sharp
line of demarcation between the two branches
of this science; therefore we define chemical
technology best by designating it as that branch
of industrial science which treats of the pro-
cesses and methods by which the nature of raw
materials is usually altered" II there be any
person in this manufacturing section of the
al
importance of scientific knowledge and skill TO
the success of practical industry, he will do
well to study this book very carefully. No other
work with which we are acquainted treats of
chemical technology so extensively and
thoroughly, or with such fulness of scientific
knowledge. 1t discusses and explains all the
processes of every kind of manufactures, in
which "the nature of raw materials is usually
altered" 1t is arranged in eight divisions. The
first treats of everything relating to chemical
metalurgy; the second Diseases the crude ma
lerials and products of chemical industry; the
third explains the technology of glass, ceramic
ware, gypsum, lime aud mortar; the fourth
treats of vegetable fbres and their technical APP
plication; the fifth gives an account of animal
substances and their industrial application; the
sixth is on dyeing and calico printing; the sew
enth discusses the materials and apparatus for
producing artificial light; the eighth is devoted
to fuel and heating apparatus. The book is a
large octave, well printed, and abundantly sup
piled with pictorial illustrations. For sale by

The EUsTACE DIAMONDS; A Novel; By
Anthony 1rolloppe. New York: Harper and
Brothers, publishers. This novel fills an octave
volume of 351 two-column pages. 1t has the
usual characteristics of Anthony Troloppe's
novels, with rather more of the sensational ele-
ment, perhaps. The chief figure in the story is
an unprincipled woman, Lady Eustace, a
young widow who claimed the "Eustace Dia-
monds" as the gift OF her husband, while, on
the otter hand, they were claimed as an heirloom
of his family, which could not be given away
from the estate. How she intrigued, how the
diamonds were not stolen as was supposed, how
they were actually stolen, how abe involved her
sell in trouble by false swearing, how she dealt
and Jared with her lovers, aud how 1t Jared with
other interesting personages; all this is told as
Mr.. Trolloppe is accustomed TO tell stories, which
ind favor With novel readers. For sale by

Roberts BROTHERS, Boston, have issued
three handsome books for young readers, which
come to us put up in a very neat paper box.
They are from the pen of a popular writer of
such books, Mrs Robert 0'Reilly, and the titles
are as folowsj Doll World" 'Daisy's Com
panions," aud "Deborars Drawer" They are
all illustrated, well printed, and handsomely
bound; and each tells It's own story 10 fashion
which youthful readers, and some of their
elders, also, we presume, will find attractive.

"SogG LIFE FOR SUNDAY SCHOOLS. ETC"
is the title Of a collection OF music published by
Harper & Brothers. 1t was prepared by Philip
Phillips, and the pages are illustrated by selec-
lions from BuDyan's Pilgrims Progress, with
pictorial illustrations, by c. Gray Parker, which
is an attractive novelty The book seems to us
good one. Those interested in Sunday school
music, will, doubtless, examine it and judge for
| themselves.
