On the 2nd of August the same two professors, aided by a third, M. Barruel, carried out a further examination of the body. Their testimony is highly technical. It is also rather revolting. I am conscious that, dealing, as I have had to, with so much arsenical poisoning (the favourite weapon of the woman murderer), a gastric odour has been unavoidable in many of my pages--perhaps too many. For that reason I shall refrain from quoting either in the original French or in translation more than a small part of the professors' report. I shall, however, make a lay shot on the evidence it supplies. Boursier's interior generally was in foul condition, which is not to be explained by any ingestion of arsenic, but which suggests chronic and morbid pituitousness. The marvel is that the man's digestion functioned at all. This insanitary condition, however, was taken by the professors, as it were, in their stride. They concentrated on some slight traces of intestinal inflammation. "One observed," their report went on, about the end of the ileum some grains of a whitish appearance and rather stubbornly attached. These grains, being removed, showed all the characteristics of white arsenic oxide. Put upon glowing charcoal they volatilized, giving off white smoke and a garlic odour. Treated with water, they dissolved, and the solution, when brought into contact with liquid hydrosulphuric acid, precipitated yellow sulphur of arsenic, particularly when one heated it and added a few drops of hydrochloric acid. These facts (including, I suppose, the conditions I have hinted at) allowed them to conclude (a) that the stomach showed traces of inflammation, and (b) that the intestinal canal yielded a quantity of arsenic oxide sufficient to have produced that inflammation and to have caused death. The question now was forward as to where the arsenic found in the body had come from. Inquiry established the fact that on the 15th of May, 1823--that is to say, several weeks before his death--Boursier had bought half a pound of arsenic for the purpose of destroying the rats in his shop cellars. In addition, he had bought prepared rat-poison. Only a part of those substances had been used. The remaining portions could not be found about the shop, nor could Mme Boursier make any suggestions for helping the search. She declared she had never seen any arsenic about the house at all. There was, however, sufficient gravity in the evidences on hand to justify a definite indictment of Mme Boursier and Nicolas Kostolo, the first of having poisoned her husband, and the second of being accessory to the deed. The pair were brought to trial on the 27th of November, 1823, before the Seine Assize Court, M. Hardouin presiding. The prosecution was conducted by the Avocat-General, M. de Broe. Maitre Couture defended Mme Boursier. Maitre Theo. Perrin appeared for Kostolo.
