Press Opinions.

"The work has evidently been prepared with great care, and, as far as we can judge, should be very useful to the dyer and colourist."—Halifax Courier.

"The volume, which is clearly and popularly written, should prove of the utmost service to all who are concerned with the practical use of colours, whether as dyers or painters."—Scotsman.

"To the practical colourist, and also to technical students, Mr. Paterson's new work will be very welcome. We are often asked to recommend books on different subjects, and have no hesitation in advising the purchase of the present volume by dyers and calico printers, as containing a mass of most useful information at a nominal price."—Irish Textile Journal.

"Mr. Paterson's work not only clearly deals with the theory of colour, but supplies lucid directions for the practical application of the theory. His work will be found exceedingly helpful, not only to the practical colourist, but also to students in our textile colleges, by forming a useful complement to their class lectures. There are several exquisitely coloured plates and a large number of other illustrations of theory and practice in colour blending, and also a series of plates with specimens of dyed fabrics attached, in explication of the author's views."—Wakefield Express.

"Mr. Paterson has little to say upon the experimental aspect or on its æsthetics, but much upon the theory of colour, especially as it bears upon the question—an all-important one to dyers, calico printers and artists, who have to produce such a variety of shades and tints—of the admixture of one colour upon another.... The author is a dyer, and in his concluding chapters keeps well before him the special wants and requirements of dyers. He writes pleasantly and lucidly, and there is no difficulty in following him, although here and there a lapse into ambiguousness occurs. The book is well printed, generously supplied with coloured plates, very nicely if not brightly got up; and the dyed patterns at the end enhance the value of the book to the dyer."—Textile Mercury.

"For some time the proprietors of The Oil and Colourman's Journal have been engaged in the publication of a series of practical handbooks intended for the use of those interested in certain branches of technology, and the present volume is the latest addition to their list. The feature which the works have in common—and it is an all-important one in treatises of this sort—is their eminently practical character. The primary aim of the publishers is to provide scientific text-books which will be helpful to those who are either actively engaged in the practice of the arts in question, or who are studying with that immediate end in view.... Mr. Paterson speaks with that assured knowledge of an expert, and in the present volume, as in that which he has already contributed to the same series, he sets forth the true foundation of the art of colouring in a manner at once comprehensive and judicious.... For dyers, calico printers and colourists in general, whose desire it is to work with accuracy in their respective branches, the treatise will prove an invaluable guide-book, provided the principles and methods it describes are studied with intelligence and care. To this end, every encouragement has been given that well-chosen examples, carefully executed plates and diagrams, and an exhaustive index can supply."—Glasgow Herald.
