ANALYTICAL EVIDENCE.
Dr. Lees, M.D., of the Brixton Road, on the 18th of September made a post-mortem examination of the body in conjunction with a Dr. Lewis. They found no morbid appearances to indicate the cause of death—the limbs were somewhat rigid, the body fairly nourished, and the stomach showed no sign of irritant poison.
“It contained,” said the witness, “six ounces of a thin reddish fluid. I put the stomach and contents into a jar, and the viscera into another. I received the bottles from the constable and the paper of powder, and saw some pills at the inquest. Among the bottles was one of the larger ones, which appeared to have contained a few ounces of good sarsaparilla—it was empty and rinsed out. One bottle contained about two grains of dried powder, adhering to the bottle. I added to the bottle a few drachms of water, two drachms of spirits of wine, thirty drops of hydrochloric acid, and two grains of dried powder. My purpose up to that time was to test for strychnia, but it was frustrated. What I had done was not sufficient to enable me to form an opinion. I had previously analysed a portion of a two-ounce phial, containing half a drachm or thirty drops of a reddish brown fluid—half a spoonful. I first tested five drops, and obtained clear evidence of strychnia. I was enabled to separate from the rest a substance that yielded strychnia. I used three separate tests; the second time with ten drops, and obtained needle-shaped crystals. I showed the colour to Dr. Bernays. I did not test the bottle for any other purpose. I left the rest (five drops) in the bottle and corked it up. Half a grain of strychnia is a fatal dose. I have been in practice fourteen years, and am of opinion that if Mrs. Wilson’s description of the symptoms is correct, they were consistent with death from strychnia. They only resemble the disease known as idiopathic tetanus. If Mrs. Wilson’s description is correct, the symptoms were not consistent with anything I know except death by strychnia—it came on so rapidly. If strychnia were administered in solution, the symptoms would come on in a very few minutes. Strychnia occasionally produces irritation of the stomach. The symptoms of poisoning by it are the rapid occurrence of twitchings in the limbs and rigidity of the muscles of the limbs, usually commencing in the lower extremities; the sense of weight on the chest, the extension of the spasms to the muscles of the trunk, the arching back of the head, the intervals of consciousness, the absence of any great difficulty in swallowing, and death in six hours. Mr. Miller’s evidence is consistent with death from strychnia.”
The cross-examination was, as in Mrs. Wilson’s case, directed to the eliciting admissions in favour of the opinion, at first adopted by Mr. Miller, that the death was due to epilepsy.
“Leaving out the ‘arching’” (opisthotonos), said the witness, “I should hesitate to say she died of strychnia; it is a leading symptom, and also that the intellect was clear at intervals. Vomiting is not usual in epilepsy. It was eight days after death that I examined the body. There was then no rigidity beyond what I might expect in death. The lungs were congested, the heart flabby and decomposed, spongy from putrefaction, and containing a little coagulated blood. Taking the appearances of the whole post-mortem examination, there were no marked ones to account for death.”
Dr. A. J. Bernays, professor of chemistry at St. Thomas’s Hospital, to whom the bottles and powder found in the room, the jars with the stomach, intestines, and viscera, and a bottle supposed to contain vomit,[96] had been handed on the 28th of October, reported the results of his analysis of their contents.[97]
“In the organs (the lungs, heart, liver, kidneys, intestines, spleen, and blood) he found no poison of any kind. The stomach was inflamed, and there was a trace of strychnia, but of no other poison. In one bottle of medicine, opium, myrrh, but no strychnia, were found, and in another only peppermint and asafœtida. The powder was innocuous, consisting of old mustard and fenugreek. In one nearly empty bottle was found a distinct sediment of Prussian blue, one of the usual ingredients in ‘vermin powder.’ He was satisfied that what Dr. Lees showed him on a watch glass was strychnia; on testing, it was found to contain the 1000th part of a grain. On the 31st of October the inspector brought two packets labelled Battle’s Vermin Killer. Poison. Lincoln—a light blue powder, a threepenny and a sixpenny packet. The first consisted of fifteen grains, containing wheat flour, Prussian blue, and crystallised strychnia. The second packet, of the same composition as the first, weighed thirty grains. The amount of strychnia was—in the threepenny packet 10·69 per cent., in the sixpenny packet 10·06 per cent., corresponding to 1·6 grains in the smaller packet. On the 9th November a threepenny and sixpenny packet of Butler’s Gloucestershire Vermin and Insect Killer for killing rats and mice, &c., was received, marked poison. The weight of the two was fifty-six grains. It was a grey powder, containing flour, soot, and barium carbonate, but no strychnia; but another packet of the same contained flour, soot, strychnia, but no barium carbonate. These ‘vermin killers,’ if used at all, should never be made or sold except by the legitimate pharmaceutists of the country, and under proper precautions.”
Mr. Justice Denman.—“A very proper suggestion for the consideration of the legislature.”
Mr. Thomas Stephenson, M.D., lecturer in chemistry at Guy’s Hospital, agreed with Dr. Lees and Dr. Bernays, and had no doubt of the correctness of their experiments.
It was also proved by the prisoner’s brother-in-law that the prisoner was in the habit of taking sarsaparilla, and that whilst the prisoner lodged with him, the witness had been using Battle’s Vermin Killer, as he was troubled with mice in his room. This he had bought at a shop in the Vauxhall Road, but he did not recollect having any of it left, or of the prisoner using it in his room. The prisoner had left Mrs. Wilson a few hours after the woman’s death, saying he was going to telegraph down the line and would be absent till the evening. He did not return until about nine on the morning of the 11th, when he said his cousin would take the child, which Mrs. Wilson dressed and gave to him, and never saw it again until the 15th, when it was lying dead in a public-house at Battersea, having been found drowned in the river. He also promised Mrs. Wilson that he would attend the woman’s funeral, but did not, and told her on one occasion that he always had strychnia by him.
