Arms and Hands. With the exception of the excessive length as compared with the stature, anomalies in the arms are rare, but the hands show some interesting characteristics, which have already been described in the first chapter of Part I, an increase or decrease in the number of fingers and syndactylism or palmate fingers. Also the lines in the palm and those on the palmar surfaces of the finger-tips show deviations from the normal type resembling characteristics of apes.
Feet. Degenerates and more especially epileptics, frequently have flat or prehensile feet and an elongated big-toe with which, like the Japanese, they are able to grasp objects.
All these anomalies vary in number and degree according to whether the subject examined is a born criminal or a criminaloid, and according, also, to the special type of crime to which he is addicted. Thieves commonly show great mobility of the face and hands. Their eyes are small, shifty and obliquely placed, and glance rapidly from one object to another. The eyebrows are bushy and close together, the nose twisted or flattened, beard scanty, hair not particularly abundant, forehead small and receding, and the ears standing out from the head. Projecting ears are common also to sexual offenders, who have glittering eyes, delicate physiognomy excepting the jaws, which are strongly developed, thick lips, swollen eyelids, abundant hair, and hoarse voices. They are often slight in build and hump-backed, sometimes half impotent and half insane, with malformation of the nose and reproductive organs. They frequently suffer from hernia and goitre and commit their first offences at an advanced age.
The cinædus is distinguished by his feminine air. He wears his hair long and plaited, and even in prison his clothing seems to retain its feminine aspect. The genitals are frequently atrophied, the skin glabrous, and gynecomastia not uncommon.
The eyes of murderers are cold, glassy, immovable, and bloodshot, the nose aquiline, and always voluminous, the hair curly, abundant, and black. Strong jaws, long ears, broad cheek-bones, scanty beard, strongly developed canines, thin lips, frequent nystagmus and contractions on one side of the face, which bare the canines in a kind of menacing grin, are other characteristics of the assassin.
Forgers and swindlers wear a singular, stereotyped expression of amiability on their pale faces, which appear incapable of blushing and assume only a more pallid hue under the stress of any emotion. They have small eyes, twisted and large noses, become bald and grey-haired at an early age, and often possess faces of a feminine cast.
Sensibility
This external inspection of the criminal should be followed by a minute examination of his senses and sensibility.
