2. During convulsive attacks, in the period of passional attitudes, under the most varied forms, by gestures in co-ordination with the hallucinations observed by the mind of the patient; we often see such persons express the most opposite sentiments—piety, erotism, and terror.

3. After convulsive attacks, in the form of despair, shame, rage, sadness, with an abundant shedding of tears.

4. Without convulsive attacks; in that case, the delirium may occur at any period; it is masked hysteria, which has a very great analogy to masked epilepsy.

The delirium of these patients, en resume, has for essential characteristics, exaltation of the intelligence, peculiar fixity of ideas, perversion of the sentiments, absence of will power, tendency to erotism. In a number of observations on delirium among hysterical cases in a state of hypnotism recently published, patients have been noted who believed that they cohabited with cats and monkeys, while some had hallucinations of phantoms and assassins—visions that resulted from complex hallucinations and have a certain similarity to those of hystero-demonomania observed in the Middle Ages; and, if the demons did not actually play the principle role in these hallucinations, it is because the imagination had not the anterior nourishment and belief in supernaturalism and no faith in the sexual relations of demons with mankind.

It was in 1491, about the time Jeanne Pothiere was on trial, that it was noticed that young girls in religious communities were subject to an epidemic mental affection, which led its victims to declare that they had fallen into the power of evil spirits. This species of delirium betrayed itself to the eyes of its observers by a series of strange and extravagant acts. These patients at once pretended to be able to read the future and prophesy. (See Calmeil, work cited.)

Abusive religious practices, false ideas of the future life, a tendency to mysticism, the fear of Hell and the snares of the Devil, the development of hysterical neurosis, in one subject, into suggestion inherent to imitation; such was the succinct history of the epidemic of the nuns of Cambrai. Jeanne Pothiere, their companion, denounced by them, was condemned to perpetual imprisonment, for having cohabited “434 times” (so the nuns said) with a Demon, and having introduced the lustful devil into their before peaceful convent. For it could have been nothing less than a demon that chased the poor young nuns across the fields and assisted them to climb trees, where, suspended from the branches, they were inspired to divine hidden things, to foretell the future, and be the victims of convulsions.

Sixty years later, in 1550, there suddenly occurred a great number of hystero-demonomaniacal epidemics similar to that in the convent of Cambrai. The nuns of Uvertet, following a strict fast, were attacked by divers nervous disorders. During the night they heard groans, when they burst out in peals of hysterical laughter; following this manifestation, they claimed they were lifted out of their beds by a superior force; they had, at the same time, contractions in the muscles of the limbs and of the face. They attacked each other in wild frenzy, giving and taking furious blows; at other times they were found on the ground, as though “inanimate,” and to this species of lethargy succeeded a maniacal agitation of great violence. Like the nuns of Cambrai, they climbed trees and ran over the branches as agile as so many cats, descending head downwards with feet in the air. These manifestations were, of course, attributed to a compact with the Devil, and the officers of the law, acting on the accusations of these nuns, arrested a midwife residing in the neighborhood, on the charge of witchcraft (sorcery). It is needless to add that the midwife died soon after.

A neurosis almost similar occurred the same year among the nuns at Saint Brigette’s Convent. In their attacks these nuns imitated the cries of animals and the bleating of sheep. At chapel one after the other were taken with convulsive syncope, followed by suffocation and œsophageal spasms, which sometimes persisted for the space of several days and condemned the victims to an enforced fast. This epidemic commenced after an hysterical convulsion occurred in one of the younger nuns, who had entered the convent on account of disappointment in love. Convinced that this unfortunate creature had imported a devil into the religious community, she was banished to one of the prisons of the Church.

At about this same time another epidemic of hystero-demonomania broke out at the Convent of Kintorp, near Strasbourg. These nuns insisted that they were possessed. Convulsions and muscular contractions which followed these attacks, along with delirium, were attributed to epilepsy. Progressively, and as though by contagion, all the nuns were stricken. When the hysterical attack arrived they uttered howls, like animals, then assaulted each other violently, biting with their teeth and scratching with finger-nails. Among those having convulsions the muscles of the pharynx participated in the general spasmodic condition. The attack was announced by a fetid breath and a sensation of burning at the soles of the feet. One day some of the young sisters denounced the convent cook, Elise Kame, as a sorcerer, although she suffered like the others from convulsive hysteria. This accusation finished the poor girl, who, together with her mother, was committed alive to the flames. Their death, most naturally, did not relieve the convent of the disease; the nervous malady, on the contrary, spread around in the neighborhood of the institution, attacking married women and young girls, whose imaginations were overpowered by the recital of occurrences within the convent walls.

We must admit that at that period doctors confounded hysteria with epilepsy. Spasms of the larynx, muscular contractions that we of the present day can provoke experimentally, as well as other phenomena of hysterical convulsions in somnambulic phases of hypnotism, were considered at that period only the manifest signs of diabolical possession. As to the stinking breath, which revealed the presence of the Devil among the nuns, that is a frequent symptom in grave affections of the nervous system; it is often a prodroma of an attack or series of maniacal convulsions. We have found that this fetidity of breath coincides with the nauseating odor of sweat and urine, to which we attribute the same semeological value as that of the mouth.
