The Great Triangle is formed by the lines of Head, Life, and Health (Plate XXV.). The larger this triangle is, the better will be the health, for the reason that the Line of Health will be further removed from the Life Line. The views of life will also be broader and the field of action as it were less limited.

When the upper angle (made by the Head and Life Lines) is acute, the subject will be more nervous, timid, and sensitive.

THE QUADRANGLE

The Quadrangle, as its name implies, is that space lying between the Lines of Head and Heart. (Plate XXV.)

To be well marked, it should be even in shape and not narrow at either end.

When marked in this way it denotes balance of judgment, level-headedness in all things, and is a most excellent sign to have.

It represents man's disposition or mental attitude towards his fellow men. When extremely narrow it indicates narrowness of views and bigotry in regard to religion.

When excessively wide, it denotes a lack of judgment in all things and too much looseness of views for one's good.
