_Lethargy_, in the depression of all parts of the body, and a predisposition on the part of the muscles to contract. _Delirium, finally_, in the impossibility of hoping to discern false from true sensations. We find, after this, that in analyzing the principal symptoms of hystero-demonomania, we easily note the characteristics of ordinary hysterical folly; we see that _it always attacks_ by preference the impressionable woman. She who is fantastic, superstitious, hungry for notoriety, full of emotions,—one who possesses to the highest degree the gift of assimilation and imitation,—the subject of nightmare, nocturnal terrors, palpitations of the heart; a woman fickle in sentiment, one passing easily from joy to sadness, from chastity to lubricity,—a woman, in a word, who is capable of all manner of deceit and simulation, a natural-born deceiver. The attacks of delirium among hystero-demonomaniacs have always a pronounced acute character; but, although violent and repeated, they are liable to disappear rapidly, and are often followed by relapse. These attacks of delirium are observed: 1. _Before the convulsive attacks_, under the form of melancholia or agitation, with hallucinations of sight and hearing. 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.
