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.
