*** OPINIONS OF THE PRESS.

"This appears to be a work for which there should be a large
demand on the part of mechanical engineers. It is no easy
matter to compile a book of this class, and the labour involved
is enormous, particularly when--as the author informs us--the
majority of the tables and diagrams have been specially prepared
for the work. The diagrams are exceptionally well executed, and
generally constructed on the method adopted in a previous work
by the same author.... The tables are very numerous, and deal
with a greater variety of subjects than will generally be found
in a work of this kind; they have evidently been compiled with
great care and are unusually complete. All the information given
appears to be well up to date.... It would be quite impossible
within the limits at our disposal to even enumerate all the
subjects treated; it should, however, be mentioned that the
author does not confine himself to a mere bald statement of
formulæ and laws, but in very many instances shows succinctly
how these are derived.... The latter part of the book is devoted
to diagrams relating to Boiler Construction, and to nineteen
beautifully-executed plates of working drawings of boilers and
their details. As samples of how such drawings should be got out,
they may be cordially recommended to the attention of all young,
and even some elderly, engineers.... Altogether the book is one
which every mechanical engineer may, with advantage to himself
add to his library."--_Industries._

"Mr. Foley is well fitted to compile such a work.... The diagrams
are a great feature of the work.... Regarding the whole work, it
may be very fairly stated that Mr. Foley has produced a volume
which will undoubtedly fulfil the desire of the author and become
indispensable to all mechanical engineers."--_Marine Engineer._

"We have carefully examined this work, and pronounce it
a most excellent reference book for the use of marine
engineers."--_Journal of American Society of Naval Engineers._

"A veritable monument of industry on the part of Mr. Foley, who
has succeeded in producing what is simply invaluable to the
engineering profession."--_Steamship._

use; they are of sufficient scope for most practical purposes,
and may be commended to engineers and users of steam."--_Iron._

engineer. Mr. Foley has compiled a very useful set of tables,
the information contained in which is frequently required by
engineers, coal consumers and users of steam."--_Iron and Coal
