"Mr. Paterson has little to say upon the experimental aspect or on its aesthetics, 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._ * * * * * =COLOUR MATCHING ON TEXTILES.= A Manual intended for the use of Students of Colour Chemistry, Dyeing and Textile Printing.
