THE GREAT TRIANGLE AND THE QUADRANGLE  
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.)
