The Publishers have spared no exertion or
expense to make this compendium everything
that it purports to be. In order to effect this,
they engaged the services of OLIVER BYRNE,
celebrated in Europe as the author of large
number of the scientific works in the language
and already favorably known here as the au-
thor of the Dictionary of Mechanics and En-
gineering.
It has been the authors endeavor to make
the work eminently practical, and to condense
the most information into the least possible
space; and after careful examination, we
DO not hesitate TO say that it is, in our opinion,
infinitely superior to any Treatise of the kind
now in use, and one that should be in the
hands not only of the mechanic and working
man, but of every person desirous of much
Information, In small compass, on almost
every useful subject We find no long
columns of figures of no use except to en-
cumber the book, but in place of this, Tables
are used, as far as necessary, by which the
reader is taught how TO produce the necessa-
ry results himself
1t would far exceed our limits 20 give even
an idea of all it contains.
Many very useful things will be found in
it which are peolliarly the authors and not
TO be met with in any other treatise of the
kind. We can mention only few. In the
first place the work is embellished with three
Steel Engravings of Steam engines,-the Sta
tionary, Locomotive, and Ship Engine, in the
very best style of Engraving, all the parts of
which are accurately pointed out and explain
ed by numbers, so that any person perfectly
ignorant of their use would be able to learn
how to manage one.
ALSO,
An ALMANAC FOR ALL TIME, very USE
ful as well as curious arrangement, peculi-
iarly the authors.
A UNIVERSAL THERMOMETERS, showing the
sensible heat Of many substances according
to the three most approved thermometers
BY inspection the degrees of one. of these
thermometric scales are converted into de-
grees Of either of the others. This has been
got up at great expense, and is onl ly to be
found in this book
How Logsrithms are applied to facilitate
the calculations Of the Mechanic, Machinist,
and Engineer.
The most accurate Planetary Tables
Tonnage of Ships.
The Thickness of water Pipes Of Iron,
Cast Iron, Copper, Lead, &c.
Dilation of Solids by Heat
Wind and Windmills-presure of the wind
moving at given velocities
The Weights of different countries com.
pared.
Torsion, Twisting, and Cohesive powers
of Bodies.
Alloys and Compounds.
The Retardation of Railway Trains.
Mechanical Powers
Wheels, Drums, and Pullevs.
Gearing, and the Teeth of Wheels.
Dimensions Of Wheels in actual use,
Moduli of Elasticity, &c.
The Index to the book is very copious and
well arrangea, and to that we refer the read
er for further synopsis of its contents.
