A mechanical or artificial hand in copy-book style, lightly and delicately traced.
Characteristic signature, connected and rapidly traced letters expressing great animation and mental activity.
A natural hand, letters vary in size, written with great spontaneity and expression.
A restrained hand, letters slowly and deliberately traced, indicating a slow intelligence and perception.
The above is a comparison of the students' and criminals' handwriting, the selections being made from the records of each class.
The tremor of feebleness is shown in this signature. This was written by a gentleman ninety-two years of age. Writing of one who is ill or feeble is usually characterized by a light stroke. The simulated tremor of a skilful penman is rarely successful in deceiving a trained eye.
This signature represents the tremor due to illiteracy. The tremors and angular features shown are by no means indicative of lack of power, but the power is misdirected.
The signature of Ivan Wilson, herewith given, will serve as an illustration of the tremor almost inseparable from forgery. The tremors of a simulating hand are never so numerous nor so fine as real tremors.
The first signature is the original. The second is a bungling traced forgery and the third is a forged freehand. Taken apart from one another they are clever enough to deceive, but studied together here the fraud and deception is readily apparent.
We give above a genuine signature with a forged tracing and a forged free-hand. You can readily detect the forgeries when these signatures are placed together and explained. It gives one points on how to study forged and disputed signatures.
We show herewith two enlarged finger-prints. These are taken from the index finger and are used in many cases instead of thumb-prints.
The above illustrations are fac-simile impressions of the dermal furrows of the right and left thumbs of four different persons. The left thumbs are in the top row, the right thumb being below. These are enlarged to bring out the distinctive points. You will note that no two are alike and it is absolutely impossible to forge or duplicate the thumb-print of any person.
"Thumb-prints Never Forged" on page 115.
Promiscuous thumb-prints taken at random, easily distinguishable in the original impression but not enlarged as in above illustration. A photographic reproduction showing the lines without enlargement almost impossible.
