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 British Daily 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.

Press Opinions.

"There can be no doubt that the publication will take a high place in the list of scientific text-books."—London Argus

"We can heartily recommend this volume to all interested in the subject of essential oils from the scientific or the commercial standpoint."—British and Colonial Druggist.

"Mr. Parry has done good service in carefully collecting and marshalling the results of the numerous researches published in various parts of the world."—Pharmaceutical Journal.

"At various times monographs have been printed by individual workers, but it may safely be said that Mr. Parry is the first in these latter days to deal with the subject in an adequate manner. 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 himself au fait with 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 Australian Brewers' Journal.
