Press Opinions.

"The book is worthy the attention of the trade."—Worcester Herald.

"The treatise is arranged with great care, and follows the processes described in a manner at once clear and convincing."—Glasgow Record.

"A most useful manual dealing in an intelligible and interesting manner with the colour printing of carpet yarns."—Kidderminster Times.

"An eminent expert himself, the author has evidently strained every effort in order to make his work the standard guide of its class."—Leicester Post.

"The book, which is admirably printed and illustrated, should fulfil the need of a practical guide in the colour printing of carpet yarns.—Nottingham Express.

"The subject is very exhaustively treated in all its branches.... The work, which is very well illustrated with designs, machines, and wool fibres, will be a useful addition to our textile literature."—Northern Whig.

"It gives an account of its subject which is both valuable and instructive in itself, and likely to be all the more welcome because books dealing with textile fabrics usually have little or nothing to say about this way of decorating them."—Scotsman.

"The work shows a thorough grasp of the leading characteristics as well as the minutiae of the industry, and gives a lucid description of its chief departments.... As a text-book in technical schools where this branch of industrial education is 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.
