In 1938, Ranald published his findings in his book, "How to Know People By Their Hands," even though he was concerned about giving too detailed a description of Hitler's palm.
Ranald feared that "others, finding signs similar to one or two of Hitler's in their own hands may assign to themselves the qualities which make Hitler what he is," he writes.
"For this reason, I wish again to emphasize that no single sign or set of signs can be read apart from the indications of the hand as a whole. It is only from the study of the totality of a hand that an accurate analysis can be made."
Ranald also studied the palms of Italian fascist leader Benito Mussolini, President Franklin D. Roosevelt, and Walt Disney.
Life Line
Hitler's line of life, which arches around his thumb, ends in a cross near the base of his hand. The cross signals a "violent end" to his life, according to Ranald.

Destiny Line
"This line marks the destiny of a man whose fate is out of his control," Ranald writes. Hitler's destiny line on his palm shows that he will serve "an awful, tragic role" in life.
"The destiny line, you will note, stretches unbroken and bare from its tragic beginning to its violent end," Ranald writes.

Underneath the Jupiter and Saturn fingers
The base of the Jupiter finger first shows that Hitler is a bully with "boundless ambition" that demands "blind submission from everyone," according to Ranald.
The base of the Saturn finger indicates "moodiness, wide swings from one emotional extreme to another [and] suicidal morbidity at one moment..." His fingers also show that he is delusional and obsessed with power.

Line of head
Hitler's line of head ends in the middle of his palm which indicates "some kind of weakness - functional or organic - of the brain," Ranald writes.

Heart line
Hitler's short and broken heart line shows that he is frustrated, bitter, and cruel. "The broken, distorted girdle of Venus above the line of heart accentuates the destructiveness and unnaturalness of this hand," Ranald writes.
