THE LINE OF HEAD OR THE INDICATIONS OF THE MENTALITY The object of the following chapters is to give clear and unmistakable instruction on the lines and markings of the hands, both from the student's standpoint and from that of the general reader.

This is not usually the course adopted in books printed on this subject which have to appeal to a general public.
During my twenty-five years' professional experience in England, America, and other countries, I have carefully noted down the questions that are not answered in books published on this subject.

I have also recorded what are the difficulties that arise in the minds of those students who meet this, that, or the other mark or line and search in vain for some explanation as to its meanings.

I may add that there is not a single point on which I give information that has not been proved by me from probably thousands of cases that have come before me during my own professional experience.
As regards illustrations, I have endeavoured to make these of the simplest and clearest kind possible.

I have every confidence that if they are carefully studied, no student can fail to grasp this subject in a masterful manner, and that whoever acts upon the advice I give in these pages, cannot fail to become successful as an interpreter of this study.
In all my work I regard the Line of Head (page 11) or the Line of Mentality as the most important sign that can be found in the hand.
A Line of Head is like the needle in the compass, without a true knowledge of which it is impossible to grasp the "direction of the subject." I have seen more mistakes caused by a lack of grasp of this point than by anything else.
I have seen, for example, many students make the mistake of paying great attention to what looked like a good Line of Sun or Success, and, at the same time, not noticing a weak, badly formed Line of Head, which contradicted the promise of success given by the various lines.
