M. de Milliere, a gentleman of Maine, certified that, being present at the Exorcism of Sister Clara, and on his knees, the Devil asked him whether he was saying a De Profundis for his wife, which was the case. The Marquis de la Mothe, son of M. de Parabel, governor of Poitou, certified that sister Louise de Nogeret had disclosed his most secret faults in the presence of Father Tranquille, and of Madame de Neuillant, his aunt.

The same M. de la Mothe also asked an Exorcist to make Sister Clara, who was in the convent, come out, kneel down, and say an Ave Maria; she came after repeated commands, and obeyed.

Chevalier de Meré, who was present, asked the Devil on what day he had last confessed. The Devil answered Friday. The Chevalier acknowledged this to be correct; whereupon Sister Clara withdrew. But as he wished to try the Devil again, he begged the exorcist to make her return, and whispered some words to the Marquis and the Monk, for the nun to repeat. The exorcist refused, as the words were indecent. He changed them, therefore, into Pater, et Filius et Spiritus Sanctus! He whispered these words so low, that the exorcist could hardly hear them. The nun, who was in another room, came at the command of the Father, and addressing the Chevalier, first said the indecent words the monk had refused, and then repeated several times Gloria patri et filio et Spiritui Sancto. She was ordered to say the words exactly as she had been desired, but she said she would not.

The Bishop of Nîmes, being present at an exorcism by Father Surin, begged him to order something in difficult Latin; and the Demon thereupon performed what was wanted.

A Jesuit wishing to try what so many people stated they had experienced, gave an inward order to a demon who had been exorcised; and then immediately another. In the space of a second he gave five or six orders, which he countermanded one after another; and thus tormented the Devil, who was ordered to obey his intentions. The Demon repeated his commands aloud, beginning by the first, and adding, "But you wont," and when he had come to the last he said, "Now let's see whether we can do this."

"When it rained," says Father Surin, "the Devil used to place the Mother Superior under the water spout. As I knew this to be a habit of his, I commanded him mentally to bring her to me; whereupon she used to come and ask me: 'What do you want.'"

Another thing which struck the Exorcists, was the instantaneous answers they gave to the most difficult questions of Theology, as to grace, the vision of God, Angels, the Incarnation and similar subjects, always in the very terms used in the schools.

The corporal effect of possession is a proof which strikes the coarsest minds. It has this other advantage, that an example convinces a whole assembly.[11]

Now the nuns of Loudun gave these proofs daily. When the Exorcist gave some order to the Devil, the nuns suddenly passed from a state of quiet into the most terrible convulsions, and without the slightest increase of pulsation. They struck their chests and backs with their heads, as if they had had their neck broken, and with inconceivable rapidity; they twisted their arms at the joints of the shoulder, the elbow and the wrist two or three times round; lying on their stomachs they joined their palms of their hands to the soles of their feet; their faces became so frightful one could not bear to look at them; their eyes remained open without winking; their tongues issued suddenly from their mouths, horribly swollen, black, hard, and covered with pimples, and yet while in this state they spoke distinctly; they threw themselves back till their heads touched their feet, and walked in this position with wonderful rapidity, and for a long time. They uttered cries so horrible and so loud that nothing like it was ever heard before; they made use of expressions so indecent as to shame the most debauched of men, while their acts, both in exposing themselves and inviting lewd behaviour from those present, would have astonished the inmates of the lowest brothel in the country; they uttered maledictions against the three Divine Persons of the Trinity, oaths and blasphemous expressions so execrable, so unheard of, that they could not have suggested themselves to the human mind. They used to watch without rest, and fast five or six days at a time, or be tortured twice a day as we have described during several hours, without their health suffering; on the contrary, those that were somewhat delicate, appeared healthier than before their possession.

The Devil sometimes made them fall suddenly asleep: they fell to the ground and became so heavy, that the strongest man had great trouble in even moving their heads. Françoise Filestreau having her mouth closed, one could hear within her body different voices speaking at the same time, quarrelling, and discussing who should make her speak.
