Here are some from Montgeron, translated into English:

I give below the account derived from Carré de Montgeron, which is on every point confirmed by the pamphlet entitled: "Vains efforts des mélangistes." The two hostile parties unite in attesting the following facts, that are supported, moreover, by numerous certificates.
"It is a matter of daily experience" (I quote, now, from Montgeron), "that the convulsionaries are more or less relieved in proportion as the blows administered are more or less heavy. . . . It has been proved by innumerable witnesses that when they are violently struck in the pit of the stomach with an iron instrument (this is one of the secours they most ordinarily demand), the instrument buries itself in their body, sometimes appearing to penetrate as far as the spine; and the further it enters into the stomach, the more relief the convulsionary experiences.
"The author of Vains efforts says : 'Jeanne Mouler, a young woman of twenty-two or three years of age, having supported herself against the wall, one of the stoutest men seized a firedog, weighing, it was said, twenty-five or thirty pounds, and struck her powerful blows in the stomach. This operation was repeated on various occasions, and at one time more than a hundred blows were counted. Another day, having given her sixty, he tried the effect of similar blows on a wall, and it is stated that at the twenty-fifth blow, he made an opening in it.' . . . The fire-dog here in question weighs twenty-nine or thirty pounds. It was with this instrument that the convulsionary submitted to the most terrible blows in the very pit of the stomach. ... I declare that I am the man of whom the author speaks as the brother who tried on a wall the effect of blows similar to the ones he had just given to this convulsionary. ... It was in vain that I employed, throughout, all the strength I could exert to redouble the weight of my blows ; the convulsionary complained that they procured her no relief. She compelled me to give the fire-dog into the hands of a very large, strong man, standing among the spectators. This person did not spare her. Instructed by my experience, that the blows could not be too violent, he struck her with so much force in the pit of the stomach, as to shake the wall against which she was leaning. The convulsionary made him give her in succession the hundred blows she had at first demanded, counting for nothing the sixty received from me." . .
"'The exercise of the plank succeeded,' continues the author of Vains efforts. 'They placed upon the convulsionary, lying on the ground, a plank which entirely covered her; then, as many men mounted on this plank as it could hold. The convulsionary bore the weight of them all.' . . . More than twenty men have been seen gathered together on this plank, which was supported by the body of a young convulsionary. .... The body of this girl resisted the weight of more than three thousand, sometimes more than four thousand pounds— more than sufficient to crush an ox." . . .
"' The exercise of the stone (caillou) was not less perilous,' again remarks the author of Vains efforts. 'The convulsionary, lying on her back, a brother took a stone weighing twentytwo pounds, and with it inflicted repeated blows on her breast.' . . . It is to be observed that the person who struck her with this stone, placed himself on his knees at the side of the convulsionary, who was lying on the floor, that he raised the stone nearly as high as he could, that, after a few light trials, he precipitated it with all his strength upon the breast of the convulsionary, and gave her in succession a hundred similar blows. At each blow, the whole room shook." . . .....
"' The Salamander,' says the author of Vains efforts, ' cried: "Barley sugar!" This barley sugar was a stick thicker than the arm, sharp and pointed at one end. The convulsionary, in the centre of the chamber, curved her body in the form of a bow, and, balancing herself by her hands, rested on the point of the barley sugar; in this position, she cried out, 'Biscuit! Biscuit!' This was a stone weighing about fifty pounds. It was attached to a cord which passed through a pulley nailed to the ceiling of the room. Raised to the pulley, it was several times allowed to- fall on the stomach of the sister, her loins bearing all the time on the barley sugar.' . . . Neither the skin nor the flesh received the least injury, or suffered the slightest pain."
"A certain convulsionary receives, three time a week, the most terrible secours. Seated on the ground, the back against the wall, she induces those who come to witness her convulsions, to kick her in the stomach two thousand times in succession. . . . Extended on the ground, she causes herself to be violently struck with billets of wood on every part of the body. . . . Standing erect, her back against the wall, she takes a spit used in roasting meat, the strongest she can find; she places its point against the pit of her stomach, in the region of the short ribs; she then makes four, five, and six persons push against it, with all their strength, so that the spit bends perfectly crooked. . . . She sometimes puts the point of the spit to her throat or her forehead. ... In short, for the last two months, she has submitted every part of her body to sword thrusts. . . . Although her skin is indented by their points, and a slight red mark sometimes remains, yet the flesh is never cut." . . .
"Gabrielle caused the point of a certain rod to be put to her throat, just below the chin, and the point of a similar rod to be placed in the cavity at the back of her neck. Two persons, at the same time pushed against these two rods, with all their strength, repeating the operation several times in succession. But in vain did they try to make the points of the two rods penetrate beneath the skin—not the slightest puncture could be perceived. . . . Gabrielle, lying on her back, placed the edge of a shovel against her larynx, that is to say, exactly over the windpipe. She persuaded one of the spectators to exert himself to the utmost in pushing this shovel perpendicularly against her throat. . . . and she felt only an agreeable and salutary impression." . . .

In 1737 he was at the house of a Mme de Vieuxpoint where some thirty people, priests and laymen, were engaged in prayer with Jeanne Mouler. The police burst in. At first those present refused to give their names, but finally a list was made out and carried to Hérault. After two hours orders were received to convey twelve of the prisoners to the Bastille. "Milord Perth Comte de Drummont" was liberated this time, but two years later, on October 30th 1739, he was imprisoned. (See Nouvelles ecclésiastiques 1737, p.194-5

On that morning at six o'clock the police entered the country house of M. d'Angervillers at Lardy. Everyone was still in bed, but they arrested Gabrielle Mouler, Lord Drummond and three others, piled them on a cart and sent them to the Bastille. (Archives de la Bastille xv, p.33-40)
