taught, the book is
valuable, or it may be perused with pleasure as well as profit by
any one having an interest in textile industries."--_Dundee
Courier._

"The book bears every mark of an extensive practical knowledge of
the subject in all its bearings, and supplies a real want in
technical literature. Chapters IX. and X., on the science of colour
mixing and colour matching respectively, are especially good, and
we do not remember to have seen the bearing of various kinds of
light, and of the changes from one kind of light to another on the
work of the colourist, so well treated elsewhere."--_Dyer and Calico
Printer._

"It is thoroughly practical, and contains much information which has
not hitherto appeared in book form. It is pleasing to note that the
practical part is not crowded out with purely 'practical recipes'. A
few typical examples are given, and the rest is left to the common
sense and judgment of the printer or works' chemist. Another
pleasing feature is the accounts given here and there of the
author's own researches on the subject. The work will be of interest
to printers of wool generally, and to those engaged in the dyeing of
this fibre."--_Journal of the Society of Dyers and Colourists._
