"This little volume shows the general scheme used by Dr. Blackford in using color to determine character. It is not a text book, --that belongs in the author's extraordinary study course teaching people in detail the entire science, and how to use it, --but it is marvelously suggestive and illuminating. If it will only prove an alluring stepping stone for the reader toward the full comprehension and mastery of a science as essential as it is new, the volume will a thousand times repay him or her for the reading"--Preface.
