Press Opinion.

 put 'brains' into his work. The various classes of colouring matters are carefully described 

 .and the process by which the lakes are produced fully discussed." Northern Dailv Telegraph.

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, extend- 

 ng over a long period. It gives, under separate headings, the principal ingredients and im- 

 purities 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 as his crucibles and filter paper." Manchester 

 Courier.
