COLOR AND ITS APPLICATIONS

Second Edition, Revised and Enlarged.

6 x 9, 150 illustrations, 4 color plates, 431 pages. $4.50

The object of this treatise is not only to discuss the many applications of color, but to establish a sound scientific basis for these applications. The book is authoritative, well illustrated, and contains many references and a wealth of new material. It was written by an investigator in the general field of color and is therefore not narrowly limited in scope. It fills a distinct gap that has existed on the book shelves.
