The interrogatory was then directed to the death of Auguste Ballet. Castaing said that Auguste Ballet had left him all his fortune on account of a disagreement with his sister. Asked why, after Auguste's death, he had at first denied all knowledge of the will made in his favour and deposited by him with Malassis, he could give no satisfactory reason. Coming to the facts of the alleged poisoning of Auguste Ballet, the President asked Castaing why, shortly after the warm wine was brought up on the night of May 30, he went up to the room where one of the servants of the hotel was lying sick. Castaing replied that he was sent for by the wife of the hotel-keeper. This the woman denied; she said that she did not even know that he was a doctor. "According to the prosecution," said the judge, "you left the room in order to avoid drinking your share of the wine." Castaing said that he had drunk half a cupful of it. The judge reminded him that to one of the witnesses Castaing had said that he had drunk only a little. A ridiculous statement made by Castaing to explain the purchase of morphia and antimony in Paris on May 31 was brought up against him. Shortly after his arrest Castaing had said that the cats and dogs about the hotel had made such a noise on the night of May 30 that they had disturbed the rest of Auguste, who, in the early morning, had asked Castaing to get some poison to kill them. He had accordingly gone all the way, about ten miles, to Paris at four in the morning to purchase antimony and morphia to kill cats and dogs. All the people of the hotel denied that there had been any such disturbance on the night in question. Castaing now said that he had bought the poisons at Auguste's request, partly to kill the noisy cats and dogs, and partly for the purpose of their making experiments on animals. Asked why he had not given this second reason before, he said that as Auguste was not a medical man it would have been damaging to his reputation to divulge the fact of his wishing to make unauthorised experiments on animals. "Why go to Paris for the poison?" asked the judge, "there was a chemist a few yards from the hotel. And when in Paris, why go to two chemists?" To all these questions Castaing's answers were such as to lead the President to express a doubt as to whether they were likely to convince the jury. Castaing was obliged to admit that he had allowed, if not ordered, the evacuations of the sick man to be thrown away. He stated that he had thrown away the morphia and antimony, which he had bought in Paris, in the closets of the hotel, because, owing to the concatenation of circumstances, he thought that he would be suspected of murder. In reply to a question from one of the jury, Castaing said that he had mixed the acetate of morphia and tartar emetic together before reaching Saint Cloud, but why he had done so he could not explain.
