The Red Thumb Mark

The Red Thumb Mark is a Fiction Crime Story Book. The book may serve a useful purpose in drawing attention to certain popular misapprehensions on the subject of finger prints and their evidential value; misapprehensions the extent of which may be judged when we learn from the newspapers that several Continental commercial houses have actually substituted finger prints for signed initials. The facts and figures contained in Mr. Singleton's evidence, including the very liberal estimate of the population of the globe, are, of course, taken from Mr. Galton's great and important work on finger prints; to which the reader who is interested in the subject is referred for much curious and valuable information.
