_By the Court._—“I saw nothing on the brain to indicate death by apoplexy. If a sudden emotion had caused death I don’t think I could have told that by the brain.” Mr. Pickering, who had been in practice as a surgeon for nine years, and was present when Mr. Champneys made the first incision through the integuments, said he then smelt the odour of prussic acid,[15] and confirmed the accounts of the previous witnesses of the experiments in Mr. Cooper’s laboratory. On _cross-examination_ he admitted that before they examined the body they were led to suppose that the death had been caused by poison, and that he had never seen a case of death from poisoning either by oxalic or prussic acid. Previous visits of Tawell to Mrs. Hart, were proved by _Kesiah Harding_, a washerwoman at Slough, in December, 1844, and particularly on the Monday week before her death, when he told the deceased that he wished her to be alone when he next came, and that he would come on the Tuesday or Saturday week. PURCHASE OF PRUSSIC ACID BY TAWELL. This was proved by _Henry Thomas_, shopman to a Mr. Hughes, a chemist in Bishopsgate Street, who said, “On the 1st of January, between twelve and two the prisoner came to the shop dressed in a great coat and usual quaker garb and asked for two drachms of Scheele’s Prussic Acid, bringing with him a ½oz. bottle with a regular label of Scheele’s Acid on it. As I could not get the stopper out, I gave it him in one of our own bottles. When about to put on a label, I believe the prisoner said “You need not,” but I would not swear it. He said he wanted it for an external application to varicose veins, paid 4_d._ for it, which was entered in the book now produced. Next day he came again between ten and two and asked for the same quantity, and, as he had broken our bottle, took it in the one he had originally brought. I had seen him frequently before and might have sold him prussic acid, but am not certain. He told me, three months before, that he had been a chemist and apothecary abroad. I do not remember his being in a hurry to catch the train and my being not able to get the stopper out. It is our practice to do it. We usually cover our bottles with leather. Attended at Aylesbury on the 13th of January, and recognised the prisoner the next morning in gaol.” The _cross-examination_ of this witness, who was evidently favourable to the prisoner and in communication with his solicitor, was directed to three points—the suitability of prussic acid to the disease in the legs from which the prisoner suffered; the effect of porter on the odour of prussic acid when mixed with it; and the amount that can be produced from apple-pips. “The prisoner,” said the witness, “told me he was suffering from varicose veins. I judged that he was, from the medicine I sold him. He rubbed his leg. The prescription now shown me would be a good external application for the ulceration produced by varicose veins.”
