A FEW OF THE MODERN BOOKS ON THE SUBJECT OF COLOR WHICH THE AUTHOR OF THIS WORK HAS FOUND MOST USEFUL _Bradley, Milton_, author of "Color in the Schoolroom" and "Color in the Kindergarden."—Elementary Color. With an Introduction by Henry Lafavour, Ph. D., Professor of Physics, Williams College. Milton Bradley and Co., Springfield, Mass. [1895]. Small 8vo., pp. [i]-iv, [1]-128; colored frontispiece ("miniature color charts made from the Bradley educational colored papers," showing 126 unnamed colors) and numerous figures in text. The present writer frankly and gratefully acknowledges that he has learned more, and learned it more easily, from this little book, which is a model of conciseness and perspicuity, than from careful study of more elaborate and authoritative works on the subject. It is therefore most heartily recommended to the student as a preliminary, at least, to the study of more technical works on color. _Bradley, Milton._—The Evolution of a Practical System of Color Education based on Spectrum Standards.
