Functional Characteristics. These are of great importance. Hysterical subjects manifest special sensibility to the contact of certain metals such as magnetised iron, copper, and gold. Characteristic symptoms are the insensibility of the larynx or the sensation of a foreign body in it (globus hystericus), neuralgic pains, which disappear with extreme suddenness, reappearing often on the side opposite that where they were first felt, the prevalence of sensory and motor anomalies on one side (hemianæsthesia), the confusion of different colours (dyschromatopsia); greater sensibility in certain parts of the body, such as the ovary and the breasts, which when subjected to pressure give rise to neuropathic phenomena (hysterogenous points); a sense of pleasure in the presence of pain, the abolition of pharyngeal reflex action, the absence of the sensation of warmth in certain parts of the body and a tendency to the so-called attacks of "hysterics." These characteristics, which are closely allied, if not precisely similar to those of epilepsy, are preceded by a number of premonitory symptoms—hallucinations, sudden change of character, contractions, laryngeal spasms, strabismus, frequent spitting, inordinate laughter or yawning, cardiac palpitations, loss of strength, trembling, anæsthesia and (just before the attack,) pains in some fixed spot, generally in the head, ovary, or nape of the neck.

Psychology. The psychological manifestations of hysterical subjects are of still greater interest and importance.

They show, on the whole, a fair amount of intelligence, although little power of concentration. In disposition they are profoundly egotistical and so preoccupied with their own persons that they will do anything to arouse attention and obtain notoriety. They are exceedingly impressionable, therefore easily roused to anger and cruelty, and are prone to take sudden and unreasonable likes and dislikes. They are fickle and easily swayed. They take special delight in slandering others, and when unable to excite public notice by unfounded accusations, to which they resort as a means of revenge, they embitter the lives of those around them by continual quarrels and dissensions.

Susceptibility to Suggestion. Of still greater importance for the criminologist is the facility with which hysterical women are dominated by hypnotic suggestion. Their wills become entirely subordinated to that of the hypnotiser, by whose influence they can be induced to believe that they have changed their sex so that they forthwith adopt habits of the opposite sex, or to entertain idées fixes—strange, impulsive, or even criminal ideas. They are, in fact, obedient automatons when under hypnotic influence, but they cannot be prevailed upon to perform acts contrary to their nature, to commit crimes or reveal secrets entrusted to them, if they are naturally upright.

Variability. Mobility of mood is a still more salient characteristic of hysteria. The subject passes with extraordinary rapidity from laughter to tears "like children," says Richet, "who laugh immoderately before their tears are dry."

"For one hour," says Sydenham, "they will be irascible and discontented; the next, they are cheerful and follow their friends about with all the signs of the old attachment."

Their sensibility is affected by the most trifling causes. A word will grieve them like some real misfortune. Their impulses are not lacking in intellectual control, but are followed by action with excessive rapidity. Although of such changeable disposition, they are subject to fixed ideas, to which they cling with a kind of cataleptic intensity. A woman will be dumb or motionless for months, on the pretext that speech or motion would injure her. But this is the only form of constancy they exhibit, otherwise they are indolent by nature. Sometimes they will show activity for a few days only to relapse again into idleness.

Erotomania. This is almost a pathognomonical symptom and is shown in hallucinations and nightmares of an erotic character, preceded by epigastric aura. This erotomania is so impulsive that hysterical women frequently engage in a liaison, from a desire of adventure or of experiencing sudden emotions. The criminality of the hysterical is always connected with the sexual functions.

Of twenty-one women found guilty of slander, nine made false accusations of rape, four accused their husbands of sexual violence, and one of sodomy. Such accusations, when made by minors, are generally full of disgusting details, which would be repugnant to any adult.

Mendacity. Another peculiarity of hysterical women is the irresistible tendency to lie, which leads them to utter senseless falsehoods just for the pleasure of deceiving and making believe. They sham suicide and sickness or write anonymous letters full of inventions. Many, from motives of spite or vanity, accuse servants of dishonesty, in order to revel in their disgrace and imprisonment. The favourite calumny, however, is always an accusation of indecent behaviour, sometimes made against their fathers and brothers, but generally against a priest or medical man. The accusations, in most cases, are so strange and fantastic as to be quite unworthy of belief, but sometimes, unfortunately, they obtain credence. The commonest method adopted for spreading these calumnies is by means of anonymous letters. In one case, a young girl of twenty-five belonging to a distinguished family, pestered a respectable priest with love-letters and shortly afterwards accused him of seduction. Another girl of eighteen informed the Attorney for the State that she had frequently been the victim of immoral priests and accused one of her female cousins of complicity. According to her story, while praying at church, a certain Abbot R... took her into the sacristy and entreated her to elope with him to Spain. She refused indignantly, and hoping to soften her, he twice stabbed himself in her presence, whereat she fainted, and on recovering consciousness, found the priest at her feet, begging forgiveness. She further accused the same cousin of having taken her to a convent, where she was seduced by a priest, the nuns acting as accomplices. A subsequent medical examination proved that no seduction had taken place and that she was suffering from hysteria.
