=Press Opinions.=

"This treatise will be welcomed by those interested in this
industry who have not secured the full advantage of a course of
scientific training."--_Chemical Trade Journal._

"In concise and lucid terms almost every ingredient used in paint
and colour manufacture is described, together with the methods of
testing their intrinsic and chemical value."--_Pontefract Express._

"Such a book of reference for paint, colour and varnish
manufacturers has long been needed, and in Mr. Hurst the publishers
have secured a compiler who is not only a well-known authority and
expert, but who has the gift of communicating his knowledge in a
concise and lucid form."--_Manchester Courier._
