"It is evidently the result of prolonged research, and cannot but prove a valuable consulting work to those engaged in the industry."—Derby Mercury.

"The practical portion of the volume is the one which will especially commend itself, as that is the part of the subject which most readers would buy the book for."—Chemist andDruggist.

"This work just issued is a very valuable treatise on the manufacture of lake pigments of the coal-tar series principally. The plan adopted by the author in writing up the subject enables the manufacture to be very readily understood.... The general properties of lakes produced from artificial colours, washing, filtering and finishing, and matching and testing lake pigments are well and exhaustively described, so that no manufacturer or user of lake pigments can well afford to be without this work."—Chemical Trade Journal.

"This is undoubtedly a book which will occupy a very high place amongst technical works, and will prove of exceptional value to all whom it immediately concerns. We have no hesitation in recommending it as one of the best works of its class we have ever read. Mr. Jennison has set about his task with a lucid style, and with a complete mastery of his subject. .. We do not think students of the technical side of the paint and colour industry can possibly spend 7s. 6d. in a more profitable way than by buying this publication."—EasternMorning News.

Press Opinions."Though this excellent little work can appeal only to a limited class, the chemists in colour works, yet it will appeal to them very strongly indeed, for it will put them on the track of short, rapid, and yet approximately, accurate methods of testing the comparative value of competing samples of raw material used in paint and colour manufacture."—North BritishDaily Mail."This little text-book is intended to supplement the larger and more comprehensive works on the subject, and it embodies the result of Mr. Jones' experiments and experiences, extending over a long period. It gives, under separate headings, the principal ingredients and impurities found in the raw materials, and is a handy work of reference for ascertaining what is valuable or detrimental in the sample under examination."—Blackburn Times."There is no attempt at literary adornment nor straining after literary effect, but the lessons are imparted in simple and concise language. This is just what a text-book should be.... The treatise is certainly most useful, and bears internal evidence of being the results of actual work in a busy manufactory and not of ephemeral cramming in a technical school. The chapter arrangement is good, the index satisfactory, and the book is altogether one which the practical chemist should keep as accessible to his crucibles and filter paper."—Manchester Courier.

His book is well conceived and well written.... He is known to have sound practical experience in analytical methods, and he has apparently taken pains to make himselfau faitwith the commercial aspects of the subject."—Chemist and Druggist."Mr. Parry's reputation as a scientist is fully established, and we can therefore accept any work emanating from his pen as being of the greatest practical value. We have perused the work before us with much care, and are convinced that the contents will be found most serviceable and its publication most opportune.... He avoids unnecessary details, but includes everything that is essential to systematic treatment, while he attempts no more 'than to give an outline of the principles involved'.... We congratulate Mr. Parry on the scientific value of his work, and hope that if the progress of the colonies in the manufacture of essential oils and perfumes equals what we are justified in expecting, it will become an Australian handbook, everywhere appreciated."—The AustralianBrewers' Journal.

Many tests are given for glue in different stages of the progress of its manufacture, and the commercial value of a commodity so much in general use is exemplified by statistics and figures. It is certainly a valuable treatise upon an article for which very little literature in any form has previously been obtainable."—Carpenter and Builder."Books on the art of glue making are more than usually scarce, and users of that article, as well as those who may be tempted to embark in the industry, should therefore welcome this book by Dr. Samuel Rideal, a Fellow of the Institute of Chemistry, and a leading authority. In this book he has collected the more important facts connected with the manufacture of glue and allied products, and stated the experience he has gained in examining various commercial samples during the past ten years.... Dr. Rideal's book must be regarded as a valuable contribution to other technical literature, which manufacturers, merchants and users may study with profit."—British Trade Journal."This volume is the latest addition to the excellent series of special technical works for manufacturers and professional and commercial men issued by the well-known publishers ofThe Oil and Colourman's Journal.

Press Opinions."The language used is quite simple, and can be understood by any intelligent person engaged in the trades dealt with."—The Clarion."This is an appalling book. It shows that there is scarcely a trade or occupation that has not a risk or a danger attached to it."—Local Government Journal."Dr. Parry has not only pointed out the 'risks and dangers of various occupations': he has suggested means for their prevention. The work is primarily a practical one."—Colliery Manager."This is a most useful book which should be in the hands of all employers of labour, foremen, and intelligent workmen, and is one of great utility to sanitary inspectors, and even on occasion to medical men."—Health."The writer has succeeded in collecting a large amount of information, and though one could wish he had presented it in a rather more attractive style, he has certainly condensed it into a very small space."—Physician and Surgeon."The little book before us is one which will be found exceedingly useful to manufacturers and even factory inspectors.... No attempt is made to show how diseases when originated are to be cured, but, acting on the sound principle that prevention is better than cure, means are stated how to avoid the harm."—Bristol Mercury."The author has endeavoured to treat the question in simple rather than in technical language, and he has lucidly catalogued the most dangerous trades and their symptoms, and in each case specified the best methods of dealing with them.... To those for whom the volume is specially designed, Dr. Parry's treatise should be a useful handbook."—Sheffield Independent."A very useful manual for employers of labour, foremen, intelligent workmen, and, in spite of the author's modesty, for medical men. We have the peculiar risks and dangers of all the dangerous trades carefully described; the mode of action of various chemicals, etc., used in different industries given, with full directions how to minimise unavoidable risks."—Leeds Mercury."Most of the trades in the country are alluded to, and upon those that are dangerous the necessary attention is bestowed, and means are recommended whereby danger may be prevented or lessened. The author has evidently studied his subject with care, and has made full use of the experience of others who have had a larger insight into the industries of the country."—British Medical Journal."The work is well written and printed, and its verbiage such as to be comprehensible to the workman no less than to the master. The careful and general perusal of a work of this nature cannot but be attended by beneficial results of a far-reaching nature, and we therefore heartily recommend the book to our readers. Medical Officers of Health and Sanitary Inspectors especially should find the work of great interest."—Sanitary Record."It is written in simple language, and its instructions can be easily followed.... There are some employers, at any rate, who are more ignorant of, than indifferent to, the slow murder of their workpeople, and if the facts so succinctly set forth in this book were brought to their notice, and if the Trade Unions made it their business to insist on the observance of the better conditions Dr. Parry described, much might be done to lessen the workman's peril."—Weekly Times and Echo.
