Another eye-witness writes to the Abbé Bignon a letter printed by Lebrun in his _Histoire critique_ cited above. "The following circumstance happened to me yesterday evening," he says: "M. le Procureur du Roi here, who, by the way, is one of the wisest and cleverest men in the country, sent for me at six o'clock, and had me conducted to the scene of the murder. We found there M. Grimaut, director of the customs, whom I knew to be a very upright man, and a young attorney named Besson, with whom I am not acquainted, but who M. le Procureur du Roi told me had the power of using the rod as well as M. Grimaut. We descended into the cellar where the murder had been committed, and where there were still traces of blood. Each time that M. Grimaut and the attorney passed the spot where the murder had been perpetrated, the rods they held in their hands began to turn, but ceased when they stepped beyond the spot. We tried experiments for more than an hour, as also with the bill, which M. le Procureur had brought along with him, and they were satisfactory. I observed several curious facts in the attorney. The rod in his hands was more violently moved than in those of M. Grimaut, and when I placed one of my fingers in each of his hands, whilst the rod turned, I felt the most extraordinary throbbings of the arteries in his palms. His pulse was at fever heat. He sweated profusely, and at intervals he was compelled to go into the court to obtain fresh air." The Sieur Pauthot, Dean of the College of Medicine at Lyons, gave his observations to the public as well. Some of them are as follows: "We began at the cellar in which the murder had been committed; into this the man with the rod (Aymar) shrank from entering, because he felt violent agitations which overcame him when he used the stick over the place where the corpses of those who had been assassinated had lain. On entering the cellar, the rod was put in my hands, and arranged by the master as most suitable for operation; I passed and repassed over the spot where the bodies had been found, but it remained immovable, and I felt no agitation. A lady of rank and merit, who was with us, took the rod after me; she felt it begin to move, and was internally agitated. Then the owner of the rod resumed it, and, passing over the same places, the stick rotated with such violence that it seemed easier to break than to stop it. The peasant then quitted our company to faint away, as was his wont after similar experiments. I followed him. He turned very pale and broke into a profuse perspiration, whilst for a quarter of an hour his pulse was violently troubled; indeed, the faintness was so considerable, that they were obliged to dash water in his face and give him water to drink in order to bring him round." He then describes experiments made over the bloody bill and others similar, which succeeded in the hands of Aymar and the lady, but failed when he attempted them himself. Pierre Garnier, physician of
