The convulsive distortions of the Pythoness were but a feeble type of the phenomena of demonopathy, or the supposed possession of the middle ages. It was chiefly in convents, among the crowd of young girls and women, that these dreadful disorders were used to break out; but the visitation was not confined to convents, nor to the profession of any particular creed. Wherever religious excitation prevailed among the young and susceptible, especially when they happened to be brought together in considerable numbers, there the pest was attracted, as a fever or other malady would be attracted by a foul atmosphere. No patient in the magnetic coma ever exhibited such prodigies of endurance as thousands of the involuntary victims of these contagious manias. Who in any modern _seance_ has beheld a patient supported only on the protuberance of the stomach, with the head and limbs everted, and the arms raised in the air, and so remaining curved into the appearance of a fish on a stall, tied by the tail and gills, motionless for hours at a time? Or what rigidity of muscle in magnetic catalepsy has ever equalled that of a convulsionnaire, who would weary the strongest man, inflicting blows of a club, to the number of several thousands a day, on her stomach, while sustaining herself in an arc solely by the support of the head and the heels? Madame de Sazilli, who was exorcised in presence of the Duke of Orleans, at London, in 1631, "became, at the command of Pere Elisce, supple as a plate of lead. The exorcist plaited her limbs in various ways, before and behind, to this side and to that, in such sort that her head would sometimes almost touch the ground, her demon (say her malady) retaining her in each position immovably until she was put into the next. Next came the demon Sabulon, who rolled her through the chapel with horrible convulsions. Five or six times he carried her left foot up higher than her shoulder; all the while her eyes were fixed, wide open, without winking; after that he threw out her limbs till she touched the ground, with her legs extended straight on either side, and while in that posture, the exorcist compelled her to join her hands, and with the trunk of the body in an erect posture, to adore the holy sacrament." We seem to read the proceedings of an electro-biologist, rather than of a pastor of the church: but the parallel is not yet at an end. "The same nun," says Calmeil, "towards the close of her exorcism, executed a command which the Duke imparted secretly to her exorcist." Then follows this remarkable admission of the learned and cautious physiologist:—"On hundreds of occasions one might believe, in effect, that the Energumenes read the thoughts of the ecclesiastics who were charged with the combating of their demons. It is certain that these young women were endowed, during their excesses of hysteria or nervous exaltation, with a penetration of mind altogether unique." The children of the
