In considering this, the student must carefully observe whether this one line across the hand lies across the centre where the Head Line would naturally be, or whether it lies higher up towards the base of the fingers where the Heart Line is generally found.
If the former case, one may be sure that it is a question of head and mentality and very little heart; but if the latter, it is a question of more intensity of feeling emotion and affection than of mental intensity.
CROSSES AND SQUARES IN CONNECTION WITH THE LINE OF HEAD Small, sharply-defined crosses in any position just over or touching the Line of Head are generally signs of accidents to the Head itself.
_Under Jupiter_ (1, Plate VII.), they usually are brought about by blows caused generally by the subject's desire to rule and to be too dogmatic or tyrannical.
_Under Saturn_ (2, Plate VII.), crosses indicate injuries to the head from accidents by animals, blows by treachery, mine explosions, etc., and generally relate to accidents of a treacherous nature.
_Under the Mount of the Sun_ (3, Plate VII.), these crosses have been found to relate to accidents to the head from sudden falls, such as the subject striking his head by falling, concussion of the brain, etc.
_Under the Mount of Mercury_ (4, Plate VII.), these sharply defined crosses relate to injuries to the head due to accidents generally produced by scientific experiments or some hazardous business venture.
Small defined squares touching the Line of Head (5, Plate VII.), are in all cases signs of preservation, and they relate to the particular qualities of the Mount of the hand under which they are found.

(_See_ chapter on Mounts, page 140.) DOUBLE LINES OF HEAD Double Lines of Head (6-6, Plate VII.), are as rarely found as are cases of the single line right across the hand.

In all cases where the Double Line of Head stands out distinct and clear as two separate lines, the object will be found to have a dual mentality.

He is usually capable of an enormous amount of mental work and is of that class of people who carry out two separate mental lives with success.

It is often found with one line joined to the Line of Life and the other rising from the Mount of Jupiter; if such is the case, the interpretation would be that one side of the nature is extremely sensitive and cautious, while the other is self-confident with a great desire to rule or enforce its mental ideas on the world.
[Illustration: PLATE VII.
DOUBLE LINES OF HEAD, ALSO CROSSES AND SQUARES.] Although such a sign as the Double Line of Head gives a remarkable degree of mentality, yet I have always found it a more successful sign to find one clear Line of Head well marked on the hand than the two Lines of Head in any of their positions.
Another form of the Double Line of Head (7-7, Plate VII.), is one where the main line seems to separate about the middle of the hand, and where one branch goes across the hand and the other descends towards the Mount of the Moon.
