Forming a clear triangle, open at the base, with the Lines of Life and Head -
One of the most favorable indications to be found in the hand. Great aptitude for natural and often occult sciences.
Of course this supposes the three lines to be perfect; hence the excellent prognostic. (See Chapter on the Quad-rangle and Triangle.)
Forming a clear cross in both hands, with the Line of Mead on the Upper
Mount of Mars - Talent for the occult sciences.
This is still clearer when the line runs close to the Percussion. I explained this above.
Deep bars across the line - As many illnesses. Weak digestion. Business reverses. The deeper the bars, the more unfavorable the omen.
Malarial, even typhoid, fevers are often indicated in this wise.
Crosses near the line, but not on it -Serious changes in the subject's life.
To be verified on the Line of Fate, or the Sun, or both.
A cross toward the termination of the line, with a circle on the Line of Head - Blindness.
This is the sign I have met with most frequently when examining blind subjects' hands. More frequently yet, this cross is accompanied by a break of the Line of Head or the Line of Heart under the Mount of the Sun, the circle being absent.
A star close to the line inside the tri-angle - Blindness.
A star on the line - Sterility; childlessness; troubles connected with child-bearing. Especially so if it is found at the connection of the line with the Line of Head, with a Line of Life running close to the thumb. Also jaundice.
Besides the regular star at the connection of the Linos of Liver and Head. which indicates disorder in or malformation of the generative organs, there was found a deep dot at the bottom of the Mount of the Moon.
"The owner of these markings, although well conformed, suffered from an inactivity of the organs that prevented pregnancy. This dot by itself will indicate womb troubles or, in both sexes, disease of the kidneys.'1
A Line of Life encircling a very narrow Mount of Venus and with one conspicuous island. A Line of Liver starred it its connection with the Line of Head. A cross on the Mount of Saturn. A fair Mount of the Sun.
"Seen in the hand of a woman had been brought forth successively three children who died in birth. Finally, by dint of almost incredible care, she became the mother of a strong and healthy babe."
A star on the Line of Liver on the upper part of the Mount of the Moon - A jaundice of one month's duration. A black spot or dot instead of a star - A jaundice of six months' duration.
An island on the line, with the Line of Fate or the Line of the Sun broken or cut by a deep bar - Bankruptey.
With many islands and narrow, fluted nails - Consumption.
This is more usually revealed by the poor shape of the Line of Head, gonerally much islanded.
A large island at the start - Somnam-bulism.
In the right hand, a very-poor Heart Line and a Line of Liver islanded at the start, and going straight to the Mount of Mercury. In the left hand, a Line of Fate beginning with two islands forming an 8, and going straight up to the Mount of Saturn.
"Seen in a woman who was all her life a sleep-walker, and had been driven to using opium to free herself from nightmares. She was evidently tormented by an excess of astral fluid."
