Press Opinions.
"The book is one that is of value to every one connected with the colouring of paper."—Paper Trade Journal.
"The great feature of the volume is undoubtedly the series of actual patterns of dyed papers, 157 in all—twelve of which, made in England, have been added to the original German series. Detailed formulæ are given for the preparation of the pulp for each, and the tints of the samples practically form a key, by means of which the accuracy of the student's or practitioner's experiments can be tested.... On the whole the publication is one of distinct importance to the trade, and will no doubt speedily become a standard work of reference amongst papermakers, both in the 'lab.' and the office, as well as being an excellent text-book for the use of students in the increasing number of technical institutes in which papermaking is taught."—World's Paper Trade Review.

Press Opinions.
"Should prove of great service to all who are either engaged in or interested in the art of enamelling."—Jewellers and Watchmakers' Trade Advertiser.
"I must inform you that this is the best book ever I have come across on enamels, and it is worth double its cost."—J. Minchin, Jr., Porto, Portugal, 22nd July, 1900.
"This is a very useful and thoroughly practical treatise, and deals with every branch of the enameller's art. The manufacture of enamels of various colours and the methods of their application are described in detail. Besides the commoner enamelling processes, some of the more important special branches of the business, such as cloisonne work are dealt with. The work is well got up, and the illustrations of apparatus are well executed. The translator is evidently a man well acquainted both with the German language and the subject-matter of the book."—Invention.
