Francois Desgrais, officer, deposed that when he was given the king’s orders he arrested the marquise at Liege; that he found under her bed a box which he sealed; that the lady had demanded a paper which was in it, containing her confession, but he refused it; that on the road to Paris the marquise had told him that she believed it was Glazer who made the poisons for Sainte-Croix; that Sainte-Croix, who had made a rendezvous with her one day at the cross Saint-Honore, there showed her four little bottles, saying, “See what Glazer has sent me.”  She asked him for one, but Sainte-Croix said he would rather die than give it up.  He added that the archer Antoine Barbier had given him three letters written by the marquise to Theria; that in the first she had told him to come at once and snatch her from the hands of the soldiers; that in the second she said that the escort was only composed of eight persons, who could he worsted by five men; that in the third she said that if he could not save her from the men who were taking her away, he should at least approach the commissary, and killing his valet’s horse and two other horses in his carriage, then take the box, and burn it; otherwise she was lost.

Laviolette, an archer, deposed that on the evening of the arrest. the marquise had a long pin and tried to put it in her mouth; that he stopped her, and told her that she was very wicked; that he perceived that people said the truth and that she had poisoned all her family; to which she replied, that if she had, it was only through following bad advice, and that one could not always be good.

Antoine Barbier, an archer, said that the marquise at table took up a glass as though to drink, and tried to swallow a piece of it; that he prevented this, and she promised to make his fortune if only he would save her; that she wrote several letters to Theria; that during the whole journey she tried all she could to swallow pins, bits of glass, and earth; that she had proposed that he should cut Desgrais’ throat, and kill the commissary’s valet; that she had bidden him get the box and burn it, and bring a lighted torch to burn everything; that she had written to Penautier from the Conciergerie; that she gave him, the letter, and he pretended to deliver it.
