“I knew Mrs. Hart, and went to see her at Salthill on the 26th September, 1843. She had a child of mine in her care. I was there from three to four months, in which time I saw Mr. Tawell there twice. On the 30th of September he came, and in ten minutes after, Mrs. Hart sent me out for a bottle of stout, which I got and gave to her. She took it into the room where he was. Shortly after she came out and sent me for a sheet of paper, leaving Mr. Tawell in the room with the stout. When I came back she said to me ‘I am so ill, I shall be obliged to tell my master to go; I am so sick, my head is so bad.’ She was very sick, and I helped her upstairs to bed. After she got upstairs she was sick again. She was in very good health when Tawell came. She said she only drank one glass of porter and felt sick directly afterwards. I went down again and saw eighteen sovereigns on the table, which I put into a drawer. There was some porter in the glasses and in the bottle. That in the glasses I threw away, and drank that in the bottle, and it did not make me ill. Mrs. Hart complained of being very giddy, but did not say anything about her throat.” ANALYTICAL EVIDENCE. _Mr. Cooper_, the Analytical Chemist and Lecturer on Medical Jurisprudence, was then called and examined by _Serjeant Byles_. “On the 3rd of January,” said the witness, “Messrs. Champneys, Norblad, and Pickering called on me with a carpet bag. The bag contained a bottle (ordinary one, such as olives are usually sold in) full or nearly so with the contents of the stomach; a portion of porter in an ordinary beer-bottle, on which was a paper label signifying that it contained Guinness’s beer; a glass tumbler, about half full of what appeared to be a mixture of beer and water; a part of a plum bun, and a phial containing a few drops (perhaps about half a drachm) of a nearly colourless fluid; a small piece of pink paper, such as is generally used by apothecaries for tying over the corks of medicine phials, and had apparently been used for such purpose; and the stomach and part of the intestines. The bottle which contained the contents of the stomach was tied over with a piece of bladder, and, I think, corked as well, but of the latter I am not certain; it was opened and smelt strongly of food in the progress of digestion, it had also the smell of beer. On the application of litmus paper to the surface of the contents it became red instantly, and so very red that I was disposed to consider that Mr. Norblad and the other gentlemen were right in their conjecture as to its containing oxalic acid. A portion was now taken out of this bottle and put into a porcelain evaporating basin, to which some distilled water was added, and stirred well together with a glass rod; the basin with its contents was then placed on the heated sand bath and kept stirring until it boiled, and even after it had boiled for some minutes.
