I have read a number of books on graphology, but until I came across this book I had never been greatly impressed by any signs of progress in the study. The present book, however, is both a valuable contribution to the subject and also an excellent presentation of the definite knowledge that has been acquired about it. Handwriting is as individual as speech—the author demonstrates, for instance, how completely impossible it is for one person to imitate even the simplest straight line made by another—and it is therefore certain that it must be the expression of the most distinctive elements of the personality. What no layman can well imagine is the quite extraordinary fineness of detail in handwriting that can be distinguished and studied.
