"The book is well printed, and is a credit alike to author, printer
and publisher."--_Textile Mercury._

"It will be a valuable addition to the technical library of every
steam user's establishment." --_Machinery Market._

"Mr. Hurst has in this work supplied a practical treatise which
should prove of especial value to oil dealers, and also, though in
a less degree, to oil users."--_Textile Manufacturer._

"This is a clear and concise treatment of the method of
manufacturing and refining lubricating oils.... The book is one
which is well worthy the attention of readers who are users of
oil."--_Textile Recorder._

"We have no hesitation in saying that in our opinion this book
ought to be very useful to all those who are interested in oils,
whether as manufacturers or users of lubricants, or to those
chemists or engineers whose duty it may be to report upon the
suitability of the same for any particular class of
work."--_Engineer._

"The author is widely known and highly respected as an authority on
the chemistry of oils and the technics of lubrication, and it is
safe to say that no work of similar interest or equal value to the
general oil-selling and consuming public has heretofore appeared in
the English language."--_Drugs, Oils and Paints,_ U.S.A.

"This valuable and useful work, which is both scientific and
practical, has been written with a view of supplying those who deal
in and use oils, etc., for the purpose of lubrication, with some
information respecting the special properties of the various
products which cause these various oils to be of value as
lubricants."--_Industries and Iron._

"A mere glance at the table of contents is sufficient to show how
various are the conditions to which these materials have to be
applied, how much knowledge
