=Press Opinions.=

"This interesting volume has been kept from the pencil of the modern editor and reprinted in its entirety by the enterprising publishers of _The Pottery Gazette_ and other trade journals.... There is an excellent historical sketch of the origin and progress of the art of pottery which shows the intimate knowledge of classical as well as (the then) modern scientific literature possessed by the late Dr. Shaw; even the etymology of many of the Staffordshire place-names is given."--_Glasgow Herald._

"The historical sketch of the origin and progress of pottery is very interesting and instructive. The science of mixing is a problem of great importance, and the query how the natural products, alumina and silica can be compounded to form the best wares may be solved by the aid of chemistry instead of by guesses, as was formerly the case. This portion of the book may be most suggestive to the manufacturer, as also the chapters devoted to the subject of glazes, glasses and colours."--_Birmingham Post._

"Messrs. Scott, Greenwood & Co. are doing their best to place before the pottery trades some really good books, likely to aid the Staffordshire manufacturers, and their spirited enterprise is worthy of encouragement, for the utility of technical literature bearing upon the practical side of potting goes without saying.... They are to be congratulated on their enterprise in republishing it, and we can only hope that they will meet with the support they deserve. It seems to be a volume that is worth looking through by both manufacturers and operatives alike, and all local institutions, at any rate, should secure copies."--_Staffordshire Sentinel._

=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._

"This is a most welcome volume, and one for which we have long
waited in this country. For years we have been teaching design
applied to enamelling as well as to several other crafts, but we
have not risen to the scientific side of the question. Here is a
handbook dealing with the composition and making of enamels for
application to metals for the most part, but also for other allied
purposes. It is written in a thoroughly practical way [Transcribers
Note: Text source unreadable], and its author--Paul Randau--has made
its subject a very particular study. The [Transcribers Note: Text
source unreadable] almost all things which come from the German
chemical expert, is a model of good workmanship [Transcribers Note:
Text source unreadable] and arrangement, and no one who is in search
of a handbook to enamelling, [Transcribers Note: Text source
unreadable] whether he is a craftsman producing his beautiful
translucent colours on gold, silver and copper, or the hollow-ware
manufacturer making enamelled saucepans and kettles, can wish for a
more useful practical manual."--_Birmingham Gazette._

=Press Opinions.=

"It would be well if our English manufacturers would avail
themselves of this important addition to the extensive list of
German publications which, by the spread of technical information,
contribute in no small degree to the success, and sometimes to the
supremacy, of Germany in almost every branch of textile
manufacture."--_Manchester Courier._

"This is probably the most exhaustive book published in English on
the subject dealt with.... We have great confidence in recommending
the purchase of this book by all manufacturers of textile goods of
whatever kind, and are convinced that the concise and direct way in
which it is written, which has been admirably conserved by the
translator, renders it peculiarly adapted for the use of English
readers."--_Textile Recorder._

"A careful study of this book enables one to say with certainty
that it is a standard work on the subject. Its importance is
enhanced greatly by the probability that we have here, for the
first time in our own language, in one volume, a full, accurate,
and detailed account, by a practical expert, of the best technical
methods for the testing of textile materials, whether in the raw
state or in the more or less finished product."--_Glasgow Herald._

"The author has endeavoured to collect and arrange in systematic
form for the first time all the data relating to both physical and
chemical tests as used throughout the whole of the textile
industry, so that not only the commercial and textile chemist, who
has frequently to reply to questions on these matters, but also the
practical manufacturer of textiles and his subordinates, whether in
spinning, weaving, dyeing, and finishing, are catered for.... The
book is profusely illustrated, and the subjects of these
illustrations are clearly described."--_Textile Manufacturer._

=Press Opinions.=

"A long-felt want in the weaving industry has been supplied by the
issue of a cheap volume dealing with the subject."--_Belfast Evening
Telegraph._

"The work has been clearly translated from the German and published
with suitable illustrations.... The author has dealt very
practically with the subject."--_Bradford Daily Telegraph._

"The book, which contains a number of useful coloured diagrams,
should prove invaluable to the student, and its handy form will
enable it to become a companion more than some cumbrous work."
--_Cotton Factory Times._

"The book has been prepared with great care, and is most usefully
illustrated. It is a capital text-book for use in the weaving
schools or for self-instruction, while all engaged in the weaving
industry will find its suggestions helpful."--_Northern Daily
Telegraph._

"The various systems are treated in a careful manner; also the
different looms and their manufacture, as well as the whole
processes of the work. Yarn numbering according to various systems,
with conversion tables and numerous coloured diagrams, materially
assist to a clear comprehension of the subject."--_Northern Whig._

"The 'inside' managers of our textile mills in which the work is
complex or greatly varied, and where yarns of different materials
are in use, will find this work convenient for reference in case of
novelty or difficulty. We may also say the same in relation to the
textile student. Its description of the parts of the loom and their
functions will be of use to the latter, being of the most
elementary kind."--_Textile Mercury._

"The author attempts to fill a gap in weaving literature caused by
the neglect of many obscure points connected with the industry. A
short review is given of the power-loom as a whole, followed by a
description of the different parts of the machinery with their
advantages and defects.... The book is severely technical, but must
on that account be very valuable to the pupil who is determined to
master this industrial art."--_Cheshire County News._

"It is clear and concise, and gives just that knowledge in quality
and amount which any student of the weaving industry ought to
consider as a minimum necessary for his thorough comprehension of
his future profession. The handiness and variety of the information
comprised in Section III., dealing with the numbering and reeling
of yarns employed in the various systems in different countries,
struck us as particularly useful."--_North British Daily Mail._

"This work brings before weavers who are actually engaged in the
various branches of fabrics, as well as the technical student, the
different parts of the general run of power-looms in such a manner
that the parts of the loom and their bearing to each other can be
readily understood.... The work should prove of much value, as it
is in every sense practical, and is put before the reader in such a
clear manner that it can be easily understood."--_Textile Industries._

"The book under notice is intended as an instructor to those
engaged in power-loom weaving, and, judging by its compilation, the
author is a thorough master of the craft. It is not overloaded with
details, and he manages to compress in a book of some 150 pages all
that one can possibly wish to know about the different parts of the
machinery, whether of English or foreign make, and for whatever
kind of cloth required. A comprehensive summary is also included of
the various yarns and methods of numbering them, as well as a few
useful hints and a number of coloured diagrams for mandarin
weavings. The book is printed in bold, legible type, on good paper,
has a copious index, and is well and strongly
bound."--_Ashton-under-Lyne Herald._

"In dealing with the complicated parts of various classes of
power-looms, the writer, who is one of the professors at the Royal
Weaving School of Asch, brings to the work a thorough knowledge of
the subject, and, what is of great value, he has the gift of
communicating his knowledge in a way which is easily understood.
The smallest details of loom-setting are entered into, and a full
explanation of problems, which are a source of anxiety to many
engaged in overlooking, is given. Students will find the work an
admirable text-book, and all who are interested in weaving will see
in it a valuable addition to the literature on this subject.... The
book is in small compass, and is crowded with valuable
information."--_Bradford Observer._

calico printers and colour mixers, to whom we confidently recommend
it."--_Chemical Trade Journal._

"It is thoroughly practical, and gives in simple language the why
and wherefore of the many colour phenomena which perplex the dyer
and the colourist."--_Dyer and Calico Printer._

"We have found the book very interesting, and can recommend it to
all who wish to master the different aspects of colour theory, with
a view to a practical application of the knowledge so
gained."--_Chemist and Druggist._

"Mr. Hurst's _Handbook on the Theory of Colour_ will be found
extremely useful, not only to the art student, but also to the
craftsman, whose business it is to manipulate pigments and
dyes."--_Nottingham Daily Guardian._

=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._
