Monday, May 2, 1859.
“My Dear Mary,—I have not been able to leave for town as I expected, in consequence of my medical aid being required in a case of illness. I shall, however, see you as soon as possible. Should anything unforeseen prevent my leaving for town before the 11th, I will send you a cheque for Smith’s money and extras. I will send £5. I am quite well, and hope you are the same, and that I shall find you so when I see you—which, I trust, will not be long first. Present my kind regards to the Smiths and old friends in the house. I heard from James the other day, who said he had called on you, but that you had gone out for a walk. With best love, believe me,
“Yours affectionately,
“Thomas Smethurst.”
The case not being, in the opinion of the Richmond magistrates, strong enough to justify his committal, the prisoner was discharged. On the following day, the 3rd of May, Miss Bankes died, a coroner’s inquest was held, and the result was the re-arrest of the prisoner, and his subsequent committal for wilful murder, for which he was put on his trial on the 7th of July.[171]
EVIDENCE OF MEDICAL ATTENDANTS.
Dr. Julius said:—
“He was called in on the 3rd of April to the deceased, who was represented to be suffering from vomiting and diarrhœa. The prisoner said he believed that her liver was overloaded with bile. The witness prescribed accordingly, but without any abatement of the symptoms. There was no appearance of bile in the evacuations after the third or fourth day that he saw her, yet the symptoms of diarrhœa and vomiting continued, with a burning sensation in the bowels and soreness of the mouth. She complained of a parching throat and a burning thirst. He could not account for any of these appearances from any natural disease, and began to entertain an opinion that something of an irritant character was being administered, and in consequence desired that his partner, Dr. Bird, should see her. Did not communicate his suspicions to Dr. Bird, who, taking the prisoner’s account of the symptoms, and knowing the witness’s prescriptions, adopted his mode of treatment, but with the same want of success. The medicines were varied, but the symptoms continued the same. On this the witness communicated his fears to Dr. Bird, and he on further observation agreed that the patient was suffering from some irritant, of the administration of which they knew nothing. During this period the prisoner always saw the medical attendants, and was always present in the room when they were with the patient, and recommended or dissuaded the use of various medicines. He displayed a considerable knowledge of medicine. On the 28th of April the patient was very ill, and she repeatedly said to Dr. Bird in the prisoner’s presence that she should like some one else to be called in. On the same day the prisoner (who had always expressed a desire that the best medical advice should be obtained) suggested that Dr. Todd should be called in. On Dr. Todd’s arrival, witness gave him an outline of the case and treatment, but did not say anything of the suspicions that had arisen in his mind. Subsequent to Dr. Todd’s attendance witness procured some of the evacuations, and in consequence of the examination of them, thought it his duty to communicate with the magistrates, and the prisoner was arrested, but released on his own recognizances. Witness was unable to ascribe the symptoms to any natural cause, but if small doses of some irritant poison were administered from time to time, it would have accounted for all the appearances that had exhibited themselves. Antimony and arsenic would be the character of poisons likely to produce such results. There was neither antimony nor arsenic in any of the medicines he prescribed for her. The prisoner told him that she was not in the family way. Dr. Todd had prescribed a pill containing a quarter of a grain of sulphate of copper and a quarter of a grain of opium, to which the prisoner objected, as the copper often produced symptoms of poisoning. On the Saturday the prisoner said this medicine had produced intense burning in the mouth and throat, constant vomiting, and fifteen bloody motions—that the burning was from the “mouth to the anus.” In my judgment it could not have produced these effects. The evacuation which I obtained was previous to her taking any of these pills, as they did not arrive until afterwards. When in prison Dr. Smethurst wrote to me three letters for the particulars of the medicines that had been given, which I answered. In the first he also wished to know what solutions of arsenic were kept in our surgery, and in the third letter ashed for the date of the prescription for antimony, which had never been prescribed. He also told me that she had been ill just a week—that previously she had been in very good health, able to take long walks, in fact out a good deal.”
On his cross-examination, Dr. Julius
“Admitted that Smethurst’s communications to him of the symptoms were made in the clearest and plainest manner, and tallied with his own observations—that twice he believed he saw the patient without the prisoner being present; that previous to the 15th of April the prisoner had suggested to the witness that Drs. Hills or Hassell should be called in, and a different treatment—one of a very sedative character, which the witness considered as too powerful, and, therefore, gave in a more diluted form; that witness had not, whilst in attendance on Miss Bankes, the slightest suspicion of her pregnancy, but that, if he had known of it, he should not have made any difference in his treatment, and now that he did know of it, it made no difference in his opinion as to the cause of her death. Whilst admitting that the delivery of a woman who had a first child at the age of forty-three would be very critical, he stated decidedly, as the result of his experience, that the period of pregnancy would be far less critical than in a younger woman. Vomiting was well-known to be an early—the earliest—sign of pregnancy, but diarrhœa was not; and though he had heard of a case in which it was accompanied with diarrhœa, he had not heard of one in which the diarrhœa would not yield to any ordinary treatment, and the life of the mother was only saved by the destruction of the fœtus.”[172]
On re-examination Dr. Julius stated that “vomiting in early pregnancy had nothing to do with the burning sensation in the mouth and throat; that the sickness of Miss Bankes was decidedly not of the same character as that of pregnancy, nor was the diarrhœa such as pregnant women sometimes suffer from.” Dr. Bird, and not the witness, prescribed bismuth, acetate of lead, and nitrate of silver.
Dr. Bird, who from service in the Crimea in 1855 had had great experience and opportunity of studying bowel complaints, confirmed the evidence of his partner.
“None of the symptoms were in his opinion reconcileable with any known disease, but were such as could be accounted for from the administration of small doses of antimony or arsenic. The prisoner, he said, told him, on one occasion, that the deceased had seen her sister, and that it had very much excited her, and in consequence witness told him that it would be better if she did not come again. On the 30th he told the prisoner that he wished to take away a portion of one of her evacuations, that it might be examined under the microscope to see if any purulent matter was in it, that we might judge if there was any ulceration of the bowels—that the prisoner poured out a portion into a tumbler, which he tied over with an old newspaper, and that the witness took it to his surgery, marked it No. 2, sealed it with his own seal, and preserved it intact until delivered to Dr. Taylor with the bottle No. 1 which Dr. Julius had obtained. A third portion of an evacuation was shown to him by the prisoner, which he put into a white jam-pot, and marked No. 3. He was downstairs at the moment Miss Bankes died, but saw her every minute or two before that. He gave an ample quantity of every ingredient used in his prescriptions so as to afford a sufficient opportunity for analyzation.”
On cross-examination, he described the various remedies he prescribed, none of which would account for the symptoms, and stated that he formed his opinion that it was a case of slow poisoning by an irritant, not only from what Dr. Julius and the prisoner told him, but from the vomitings, the motions, and the lady’s own account of her symptoms.
Mr. Caudle, the assistant of Messrs. Julius and Bird, described the medicines he compounded, and Dr. Buzzard detailed the transmission of the bottles of evacuations to Dr. Taylor.
POST-MORTEM EXAMINATION.
Mr. Barwell, Assistant-Surgeon of the Charing Cross Hospital, who, with Mr. Palmer, of Mortlake, made a post-mortem examination of the body on the 4th of May, said:—
“I found the back part of the body externally of a dark purple, being full of blood from the position in which the body lay: I gathered from that that the blood was more fluid, I should say, than usual. The arms were perfectly flexible; legs very rigid; feet bent downwards and turned in, and the muscles at their bottoms very rigid, indicating cramp or spasm in the lower extremities; the abdomen drawn in and the muscles tense and hard; the tongue rough, and the papillæ more elevated than usual. There were no signs of what I could call aphthœ; the face was much emaciated and of a dull earthy colour; lower lip drawn in under the upper teeth; front of the body generally of this dull earthy colour; brain perfectly healthy; nothing wrong about the lungs—they were healthy. I saw that the liver was firm, full-sized, rather large, but did not then cut into it. I examined the uterus, and found the common signs of pregnancy and a fœtus of somewhere between the fifth and seventh week; the heart and great vessels connected with it were perfectly healthy. I examined the liver subsequently; it was slightly fatty, rather fatty; the remainder hard. The liver when it becomes fatty is usually soft, but in this instance it was hard, and it was coloured in the usual manner—speckled. Gullet healthy, no signs of inflammation on it. The outside of the stomach, the smaller end, that nearer the intestine, was red; the larger end, that where the gullet enters, was of a dark colour; in the centre it was pale. On examining the inside of the stomach, the narrow part or small end was also red; at the larger end was a black patch of effused blood; near the small end the mucous membrane was congested, that is the other end from the black spot and near where the red was. The contents of the stomach were a brown mucus mixed with blood and some bile, I should say. There were no ulcers in the stomach, nor appearance of acute inflammation. On the outside of the intestine I noticed on the 4th of May (the first examination) that its commencement was very red, the small intestines generally were inflated and minutely injected with blood, and in certain spots they were roughened by lymph, the result of inflammation, and glued together at certain turns where this lymph or glutinous inflammation was effused; they were coherent together from that cause; that did not apply to the entire length of the intestines, only to a few parts, and chiefly quite the lower parts. Those are the external symptoms. Internally, the first part of the intestine (the duodenum) was inflamed for about three inches from its commencement, but the mucous membrane was quite firm, and there was no ulceration. From that point the rest of the mucous membrane was only slightly injected, not inflamed. In the next intestine, the jejunum, the mucous membrane was still firm; in places the vessels were injected with its own blood, but this only in spots. In the ilium, or lower intestine, there was much the same appearance at the commencement as in the last, except that approaching the lower part the injections increased very much, and at last, about 3 feet from its end, the mucous membrane was greatly altered; there was a deposit of lymph therein, and a thickening of the membrane; an ill-organized granular lymph; the membrane at the same time was roughened, and the glands, which are in the intestine there, were less visible than usual. This deposit of lymph did not begin in the glands, but went over the whole surface of the intestine, and concealed the glands instead of rendering them more prominent—instead of being deposited in the glands, was rather around them at first. This brings me to the cæcum. On its mucous membrane were many very large spots. The appearances within the cæcum indicated very serious disease indeed—inflammation, sloughing, ulceration, and suppuration. Those appearances diminished as I went lower down the intestines. When I reached the termination, the colon, there was still ulceration, but in a minor degree. In the rectum there were three ulcerations. I should also say that in the cæcum were black spots of effused blood, which were also found along the rest and in the rectum. I have heard the evidence given of the symptoms exhibited during life, and the treatment adopted. Taking those into consideration, and the post-mortem appearances, they are not reconcileable with any natural disease with which I am acquainted.”
By the Court.—“What is the conclusion you have formed?”
Witness.—“That the symptoms and appearances together have resulted from some irritant, administered frequently during life.”
In his cross-examination, the earlier portion of which was occupied with questions to test the accuracy of the notes of his report, the witness explained that the hardness of the liver, which he observed, was not a stage of Cirrhosis, as he had at first written in his memoranda, “but a normal hardness, nothing extraordinary;” that the use of the term “hard” did not imply that the liver was diseased, but that the term “fatty” does.
Sergeant Ballantine.—“I think I understood you to convey that there were no signs of disease about the liver, except this fattiness?”
Witness.—“No signs at all except that. That is not a disease of a nature to affect the cæcum and the intestines in any way.”
By the Court.—“Is it in any way connected with diarrhœa and vomiting?”
Witness.—“No.”
Dr. Samuel Wilks, who had subsequently examined the intestines with Mr. Barwell, confirmed his statements as to their condition and that of the liver, and “should think Miss Bankes’ death was most probably to be attributed to an irritant.”
On cross-examination, he allowed that “severe dysentery produces great inflammation of the intestines, particularly of the larger; that inflammation, if continued, results in ulceration and destruction of the tissues; that the cæcum and rectum would be affected in that way by dysentery, and that dark spots of effused blood are also a consequence of severe dysentery.” His admission, however, rested on his reading, and not from his experience of cases of acute dysentery, as he had seen only “two cases, which they were obliged to call by that name, not being able to arrive at any other conclusion as to the cause of death.”
MEDICAL EXPERTS FOR THE PROSECUTION.
Dr. Todd, Physician to King’s College Hospital, was then called.
“Dr. Julius,” he said, “told him the nature of the case before he saw the deceased, but not his suspicions. When he saw her he noticed a peculiar expression of countenance—an expression of terror, as though she were under the influence of some one, and that was not in accordance with the appearance of a patient suffering under an ordinary disease. The abdomen was very hard—an indication of extensive inflammation in the stomach—and he was at once under the impression that she was suffering from some irritant poison. By witness’s desire an evacuation was obtained, and he directed Dr. Julius to make up the sulphate of copper and opium pills to allay irritation. He had never known any bad effect produced by these medicines, and did not think it could produce a burning sensation in the throat and stomach. If the disease had been diarrhœa, the medicines administered by Dr. Julius were the proper ones.”
Sergeant Ballantine.—“From all you have heard of this case, what in your opinion was the cause of this lady’s death?”
Dr. Todd.—“I believe that her death was caused by the administration of some irritant poison, such as arsenic, antimony, or corrosive sublimate. The only natural disease that would account for the symptoms is what would be called acute dysentery.”
On cross-examination, Dr. Todd said:—
“I have never known any case or cases of early pregnancy of a woman of about forty to forty-five years of age in which there has been violent vomiting, violent diarrhœa, and severe dysentery, which no ordinary medicines would stop, and in which the life of the mother has only been saved by the abortion of the fœtus. No such cases have come under my cognizance. I think it possible that excessive vomiting and great diarrhœa may be caused by the early stage of pregnancy, and symptoms somewhat allied to those under which this lady died; but I think it quite impossible that pregnancy alone, in an early stage, or in any stage, could, produce extensive ulceration of the bowels. I think, where it is a doubtful case, it is conclusive evidence against the theory that the symptoms were caused by early pregnancy that you found such extensive ulceration as existed in this case.”
Dr. Buzzard, who had been a staff-surgeon in the Crimea, Dr. Copland, and Dr. Bowerbank, who had had great experience of acute dysentery in tropical climates, gave it as their opinion that the symptoms were not reconcileable with that disease, but were those of the presence of irritant poison. Dr. Babington, Physician to Queen Charlotte’s Lying-in Hospital, who had attended more than 2,000 women in their confinement, did not consider that the death was in any way attributable to the fact of her being in an incipient state of pregnancy. On cross-examination, whilst admitting that cases of violent vomiting and diarrhœa in early pregnancy are recorded, said that he did not remember any one of so severe a character as to endanger life; that he did not think that the lady’s advanced stage of life had anything to do with it; that it was a complication generally at a later period of pregnancy; and that a first pregnancy between 40 and 45 years of age was not more critical in the early stage. On re-examination, with reference to six cases of dysentery, in 1841, in which he had made post-mortem examinations, he said:—
“There was not the same amount of sloughing of the cæcum as in this case, nor destruction of the mucous membrane. The glands were in a different condition. In the dysentery cases, the glands were quite destroyed, and in three of the cases there was perforation of the intestine. The symptoms in all six were different to those in this case; there was no burning sensation of the throat.”
ANALYTICAL EVIDENCE.
Dr. Alfred Swaine Taylor.—“On the 1st of May,” said the witness, “Mr. Buzzard called on me, and brought me two bottles, which he said contained matters he wished me to examine. I took about two drachms from one of these bottles (No. 2), and having first examined the test and the vessel to be employed, and ascertained that they were pure, I then made the test, and discovered a metallic deposit on the copper wire, which, in my opinion, indicated the presence of arsenic or antimony; but I could not speak to the exact metal. I did not proceed further at that time, as I desired to have the authority of a magistrate. Bottle No. 2 was then resealed in my presence by Mr. Buzzard, and taken away by him with bottle No. 1. After he left, as I was told that it was necessary to do something to save the life of a living person, though it was Sunday, I proceeded with my experiment by boiling copper gauze in the remainder of the liquid in the tube, and on examining it with a microscope, saw appearances closely resembling metallic arsenic; and I then heated a portion of the gauze covered with metal in a tube, and obtained crystals of arsenic (wire gauze with the crystals on it produced). If you take the tube out, under the microscope the crystals are perfectly clear; in this little sediment, if you put it against a dark cloth, you will see a little ring of crystals—it is quite plain in the sun light. I subsequently applied the test of nitrate of silver and nitric acid to crystals obtained in the same way, and the result convinced me that they were composed of arsenic. Next day Dr. Buzzard brought back the bottles with the magistrate’s order. I then proceeded with the examination of both bottles, and the result perfectly satisfied me that I was correct in discovering arsenic in bottle 2. My calculation was that there must have been at least a quarter of a grain mixed with the four ounces of matter in bottle 2.[173] There was no trace of mercury, bismuth, or antimony, but I did discover the presence of copper by a subsequent test; but only such a trace of it as might be accounted for from the copper pill taken on the 29th. I examined the evacuation, and came to the conclusion that it was such as would pass from a person who had taken arsenic, and I immediately advised that the antidote for arsenic, hydrate of magnesia, should be administered. I subsequently examined the other bottle, and found that it did not contain any poison or any metallic matter whatever.
“On the 5th and 7th of May Inspector McIntyre brought me a portion of the viscera of a human being, which I subsequently submitted to chemical examination. The officer also gave me a number of bottles, and several pill boxes which I numbered, and subsequently some more. There were altogether twenty-eight; and on the 14th of May others which I also numbered. In none of the twenty-eight, omitting Nos. 5 and 21, did I discover anything at all necessary you should be acquainted with. I examined them for arsenic. I then examined the bottles containing the viscera:—first, the uterus, which I did not analyse, but agree with Mr. Barwell as to its impregnation; then the œsophagus, or gullet, in which there were indications of some cause of irritation, but no arsenic or antimony; then the stomach, containing yellowish fluid with blood, and found antimony in two distinct places in the small intestines; the middle portion of the small intestines contained the largest quantity, the other part was above and below; some was found above and below that and some in the cæcum; altogether the amount found in the stomach was very small. In one kidney and in the blood of the heart there were traces of antimony, and in the blood in the jar. I was assisted by Dr. Odling, and we came to the conclusion that the quantity did not exceed from a quarter to half a grain. I found the appearance of the stomach and cæcum such as Mr. Barwell has described. I then examined the medicines prescribed by Dr. Julius, and found them to contain the ingredients of which they were represented to be composed. I then examined bottle No. 5, and found it to contain 355 grains of chlorate of potash, and free from anything else. That bottle has been accidentally broken in half. I then examined another bottle, No. 21, which appeared to contain a clear watery liquid of a saline taste, and I tested a portion of the contents by Reintsch’s test, and upon first trying the copper it was entirely consumed.[174] I made a further examination which led me to conclude that there was arsenic in the solution, but it turned out that I was mistaken, and that it did not contain either arsenic or antimony, and that the arsenical appearances originally produced came from the copper gauze. By the destruction of the gauze the arsenic in it was set free, and this destroyed the effect of the experiment. The quantity of arsenic that I discovered, I should say, was less than half a grain. In the experiment I made with this bottle, the arsenic was deposited by myself. Dr. Odling also came to the same conclusion—that the bottle contained arsenic, and we both stated that fact in our examination before the magistrates and the coroner, but we were, of course, mistaken. We believed, no doubt, at the time, that the arsenic we found was in the bottle which contained chlorate of potash—a cooling mixture. I have used the same description of gauze for many years, and have never before found arsenic in it. I shall certainly continue to use it, but shall take care not to do so with chlorate of potass.”
Serjeant Parry here called for the deposition of Dr. Taylor made before the magistrates, a portion of which was read. It stated that he had discovered arsenic in bottle No. 21, in which there was chlorate of potass; that the latter was a harmless saline mixture acting upon the kidneys, and that if poison had been given in it, its effect would probably be to carry off the noxious ingredient from the body very quickly, but that by repetition constantly of such a proceeding chronic inflammation would be created which would yield to no treatment, and would end in the death of the patient from exhaustion.
Dr. Taylor then continued:—
“At the time I gave this evidence I firmly believed that arsenic was contained in the mixture and that it had not come from my test, but had been placed there by some one. When before the coroner I expressed my opinion that the death was referable to antimony and arsenic. The finding of the arsenic in the bottle did not have any effect upon the opinion I subsequently formed with reference to the case. The moment I discovered the mistake I had made I informed Serjeant Ballantine. No arsenic was found in the body of deceased. I did not form my theory to account for the absence of arsenic from the tissues of the body, that it had been carried off by the chlorate of potass. It did not enter into my consideration beyond this, that it acts generally as a diuretic. After Dr. Odling and myself had given our evidence relative to finding the arsenic in the bottle of chlorate of potass, we thought it was possible there might be some mistake, and we made other experiments to satisfy ourselves. We made seventy-seven experiments with the same kind of gauze, and in seventy-six no arsenic was discovered: and the only instance in which it was found was in the evacuation in bottle 2.” The witness also said that he could not, after hearing the symptoms and the treatment of the deceased, attribute the death to any other cause than the administration of some irritant poison.
This witness was also cross-examined at considerable length as to the symptoms of slow poisoning by arsenic and by antimony, in which he agreed with the previous witnesses, adding to their evidence the fact of its operation in causing enlargement of the liver, and the deposit of fat in it. Hence the use of sulphide of antimony to fatten the geese used in Strasburg, in the manufacture of Perigord Pies. On the subject of dysentery he could not speak, having ceased to practise as a medical man, and confined his attention to analyses.
On re-examination, Dr. Taylor said that “the half grain of copper, given in the pill during life, would not by any action of any acid in the stomach account for the quantity of arsenic found in the evacuation; that he had examined and found no arsenic in the copper pills; and that though arsenic was found in the sulphate of copper taken from the surgery, there was not a quantity to be seen; there was no arsenic in the bismuth, and no antimony in the medicines. Arsenic is sometimes found in bismuth.”
Dr. Odling, Professor of Practical Chemistry at Guy’s Hospital, who had assisted Dr. Taylor in his experiments, 2ì”confirmed Dr. Taylor’s account in every respect, and expressed himself satisfied that there was antimony in the body of the deceased. He agreed also in attributing the death to the administration of some irritant poison, and did not know any natural disease that would account for the symptoms spoken of.”
William Thomas Brande, formerly Professor of Chemistry to the Royal Institution, and for fifty years engaged in the practice of chemistry, “had examined a portion of the liquid (the chlorate of potass), and come to the conclusion that it did not contain arsenic. Reinsch’s test for arsenic was reliable where chlorate of potass was not present.” “Our first object,” said the witness, on cross-examination, “was to get rid of the chlorate of potass, or to decompose it so as to render it inert, which we did; and we then examined the liquid in question, and found no arsenic in it.”
To the Court.—“I was not aware that Reinsch’s test would be inapplicable to such a compound, and if I had applied it, and the result appeared as it did to Drs. Taylor and Odling, I should have come to the same conclusion, that there was arsenic in the substance. The matter that has appeared since is to a certain extent new to the chemical world. We have always been aware of the presence of very minute quantities of arsenic in copper, but we have never considered it as interfering in any way until this particular case.”[175]
MEDICAL AND ANALYTICAL EVIDENCE FOR THE DEFENCE.
It will be convenient, as in the previous trials, to report at this period the medical and analytical evidence offered on the part of the prisoner, subsequent to the address of Serjeant Parry. This was devoted to the following points: (1), the absence of some of the well-known symptoms in slow poisoning by arsenic or antimony, or by both; (2), the similarity of the symptoms in this case to those exhibited in cases of acute dysentery; (3), the occurrence of severe diarrhœa, with vomiting in the early stages of pregnancy; (4), that the non-discovery of either arsenic or antimony in the tissues of the body could not be due to its being given in, or with chlorate of potass; (5), the probability that both the arsenic and the antimony found in the evacuations and intestines might be due to the presence of arsenic in the bismuth, and of antimony in the grey powders administered as medicines. In support of these opinions four doctors and analysts, all belonging to what was known as the Grosvenor School of Medicine, were examined, two of whom (Dr. Richardson and Mr. Rodgers) had given evidence for Palmer at his trial, Dr. Richardson then suggesting that Cook’s symptoms were reconcileable with an attack of Angina pectoris, and Mr. Rodgers supporting the view that if strychnia had been given to Cook, it must have been discovered in his body by chemical analysis.
Dr. Richardson, after generally asserting that the symptoms in Miss Bankes’ case were not in the main reconcileable with either slow arsenical or antimonial poisoning, or both, enumerated the following as absent if it was a case of slow antimonial and arsenical poisoning:—
“1st, the inflammation of the conjunctival membrane of the eye; 2nd, soreness of the inner surface of the nostril; 3rd, a skin disease peculiar to arsenical poisoning; 4th, excoriation, amounting to absolute destruction, possibly, of the surface at the orifice of the mucous tracts, the mouth, the anus, the lips, and the vagina—and, lastly, and, in his opinion, the most important, the absence of the peculiar nervous symptoms which he should expect to find which characterise arsenical poisoning—frequent convulsions of a violent kind, in many cases; or in others, where the symptoms may be prolonged, tremor of the whole limbs, a suppressed convulsion in fact. Although he should not expect to find all these symptoms in a case of arsenical poisoning, he believed it to be quite impossible that a case of arsenical poisoning could exist from which they would all be absent.—The results of the post-mortem” he said, “were inconsistent with arsenical poisoning, because the inflammation that would establish it was most demonstrated in the part ordinarily most free in such poisoning—that, had it been a case of arsenical poisoning, arsenic must have been found in the tissues, and, had it been given in chlorate of potass, the whole of it would not have been eliminated. He based this opinion on an experiment he had lately made on a large dog, to which in sixteen days he had given 18 grains of arsenic and 365 of chlorate of potass, in small doses, two or three times a day, and then killed and examined and chemically analysed in conjunction with Dr. Thudichum and Dr. Webb, two of the witnesses for the defence. In this animal he found arsenic in the liver, lungs, and heart, a trace in the spleen and in the kidneys, but the greater part in the liver. He could venture to say that he found half a grain.”
The Judge.—“Give me leave to say, that the value of this experiment is nothing if you give a dog arsenic day by day for sixteen days, and then it is killed, and some arsenic is found left in it; is that all it proves?”
Witness.—“No; it was done to prove whether the chlorate would eliminate the arsenic as fast as it was given.”
The Judge.—“All that the experiment proves is, that chlorate of potass does not eliminate the whole of the arsenic, because it eliminated all but half a grain.”
The witness then went on to show, by experiments on two other dogs, that the administration of chlorate made no difference either as regards symptoms, pathology, or the chemical result. Speaking again of the sweating as one of the symptoms in antimonial poisoning absent in Miss Bankes’ case, he admitted that he had seen it only in one case, and that, where it had been given in excess, for a long time, and in large doses medicinally, and that in two other cases of acute poisoning by antimony there was no particular eruption, because, as he said, the attack was not long enough. Such was all the experience he had had in cases of slow poisoning. As to the effects of antimony on the liver, he could only speak from some experiments on animals in 1856-7, and that, in reality, he had no experience at all in slow poisoning, except from experiments on animals. Of dysentery, too, he knew very little; had seen two or three cases, but had never met with it in the early stage of pregnancy; he had met with one between the third and fourth month, but not between the fifth and seventh week. He had analysed the bismuth usually administered in medicine, and had found nearly half a grain of arsenic in an ounce, and, in a case in which 90 grains of that drug had been given at the rate of 5 grains three times a day—for dyspepsia—with Drs. Thudichum and Webb he found about the fiftieth of a grain of arsenic in the urine.
The cross-examination of this witness was mainly occupied by questions about his evidence on Palmer’s trial, and in trying to elicit from him that these canine experiments had been made for the purposes of the present case. The latter he denied, but admitted that he had made them after reading the examinations before the magistrate and the coroner, and that though he did not communicate them to the prisoner, he talked about them so frequently to his colleagues at the Grosvenor School, that he was not surprised at being interviewed by the prisoner’s solicitor and asked to give evidence for his client. As to his evidence on Palmer’s trial, he maintained that he did not endorse the theory that Cook died of Angina pectoris; that he did not negative the idea of strychnia, but at last admitted that he could not deny that he went there to support the theory of Angina pectoris.[176] In the cases of the dogs his analysis was not quantitative: he was content with the fact that the arsenic was present. He negatived the idea that the ¼ of a grain of copper in the pill would produce a burning sensation from the mouth to the anus, but admitted that any irritant given for a long time would unquestionably produce that effect. The form of dysentery to which a lady with such a liver as Miss Bankes’ would be subject, would be subacute, not that arising from poison, but which is prolonged over a very considerable time: not chronic, but something between chronic and acute, but too severe to be strictly chronic; that would not harden the coats of the stomach; would produce a great deal of mischief in the bowels; would not thicken them, but probably lead to a deposit of false membrane: it would not harden them, but a false membrane would; if there was great congestion, the wall would be thicker. He had not acted as an accoucheur since 1854, but was of opinion that sickness accompanied by dysenteric diarrhœa, in the early stage of pregnancy, might have been the cause of all the appearances exhibited in this case. Diarrhœa was sometimes an incident of and caused by pregnancy; the opposite effect, constipation, was not more usual.
On re-examination, the witness qualified his admission as to the effect of the copper pill to this extent, that, “in a patient suffering from violent irritation, arising either from a natural or mechanical cause, sulphate of copper would have a tendency to increase that irritation; and he justified his reliance on the experiments on animals on their forming the great bulk of scientific knowledge in Europe on the subject of poisons and their operation on the human frame, and by the fact that the materials for forming a judgment of the effects of slow antimonial poisoning on the human subject were very bare,” and concluded by saying, that, “after his cross-examination, and his attention having been called to all the points deemed important, he still adhered to his opinion that the deceased lady might have died from natural causes.”
Dr. J. E. D. Rodgers, Professor of Chemistry in Knowle College, but for seventeen years at the Grosvenor School, agreed with Dr. Richardson that chlorate of potass would have no effect in eliminating arsenic or antimony from the human system; that the absence of arsenic or antimony from the tissues, and especially from the liver, would cause him to doubt whether the allegation of poisoning was correct, and that he did not think it possible to find it in the blood and not in the liver, “as the blood in the heart must be regarded as a sample of the whole 28 lbs. circulating in the system, and, if you find the poison in one small portion, you must find it wherever the blood flows.” He confirmed the amount of arsenic said to be in bismuth, and had found antimony in grey powder: should expect to find, in a case of slow poisoning, the symptoms spoken to by Dr. Richardson, and, if he did not find any arsenic in a body from which an evacuation containing one-sixth of a grain came, it would lead him to doubt whether the experiment had been correct.
Dr. J. L. W. Thudichum, Lecturer on Chemistry at the Grosvenor School, and a pupil of Liebig’s, attributed the death to what he called diphtheritic dysentery, of which he had seen two cases, and, on opening the body in one case, found the false membrane from which the disease takes its name. The only medical work in which he had seen this form of dysentery described was Rokitansky’s Morbid Anatomy.[177] It was not, however, at all necessary to find the false membrane, as it might be broken up and discharged, and hearing that shreddy matters were found in the evacuations, would confirm his view. He quite concurred with the previous witnesses as to the symptoms they would expect to find in a case of slow arsenical or antimonial poisoning. He had analysed grey powder and bismuth. In the former he found caustic and carbonate of lime, mercury partly oxidised, silica, with phosphate of iron, arsenic and antimony—more arsenic than antimony; in the bismuth he found both arsenic and antimony—more than a trace—enough to answer the test two or three times—an appreciable quantity. “I dare say,” he said, “there was half a grain in 20 grains. It is almost necessary, from the mode of its preparation, that it should contain arsenic.”
On cross-examination, the witness admitted that he had not made any quantitative analysis, because they were so laborious; had used in his experiment about one-sixteenth of 2 ounces of the grey powder, which he dissolved; neither the grey powder nor the bismuth had anything to do with the death of Miss Bankes, but the fact of bismuth containing arsenic might account for the traces in the evacuation, and if antimony was taken in a medicine it might account for the analysis, but this would depend upon the quantity in the medicine.
Dr. Cornelius Webb, Lecturer on Medical Jurisprudence and Toxicology at the Grosvenor School, and Physician to the Great Northern Hospital, said:—
“From all he had heard deposed to in court he was of opinion that the deceased died from natural causes that might be accounted for—that the fact of her being in an early state of pregnancy ought most decidedly to be taken into consideration; though he did not know of a case, he was of opinion, founded on practical experience and general knowledge, that severe vomiting and severe diarrhœa which would not yield to ordinary treatment may arise from an early state of pregnancy—that Miss Bankes died from dysentery, made worse by the condition of early pregnancy, and that a burning sensation in the mouth is consequent upon dysentery, and the diarrhœa and vomiting of pregnancy. All the symptoms in her case might arise from the vomiting and diarrhœa of pregnancy. The ulceration in the stomach, obliteration and partial destruction of the mucous membrane, the effusion of blood under it, and the dark patchy spots and ulcers and injection generally of the membrane might, as Dr. Wilkes said, arise from dysentery. If the deceased at one time had an affection of the womb, for which she used nitrate of silver (a pint bottle of this was found in her room), it would indicate ulceration of the neck of the womb; and if there had been such a condition of the womb an appreciable time before pregnancy, it might add to the irritation of pregnancy. Unless he found other symptoms, the vomiting, diarrhœa, sensation of the throat and the intestinal canal, accompanied by ulcerous appearances in parts of the body, would not, in his judgment, necessarily lead to the conclusion that she must be the subject of irritant poisoning—unless he found other symptoms, it would not enter his head. In a case of antimonial poisoning he should expect to find a clamminess and cold perspiration of the skin. In arsenical poisoning he should expect to find arsenic in the kidneys and the spleen, as well as the liver; should expect to find it in the liver first—it is the great criterion. And from the absence of these symptoms and appearances in this case, he was fortified in his opinion that she died from natural causes.”
The cross-examination of this witness was mainly directed to his assertion that, “in such a case as this, had he been called in at its early stage, notwithstanding he was told that she was not pregnant, and that her courses were in order, he should have examined the patient for pregnancy, especially if he found that the remedies were useless in stopping the vomiting and diarrhœa.”
“Dysentery,” he said, “was a most common disease, and in such a state as Miss Bankes was, the quarter-of-a-grain copper pill might increase the irritation. Diphtheritic dysentery was a form of idiopathic dysentery, that is, occurring without any particular poison—the Eastern form; there is a dysentery that arises from natural poison, just the same as fever. If I had been acquainted with all the symptoms I have heard described in court, I should not have dreamt of poison.”
Dr. G. F. Girdwood, who had delivered upwards of 3,000 women, strongly supported the view of the death being due to the effects of dysentery, combined with pregnancy. “Idiopathic dysentery would be its proper name—a special disease originating in itself, one single malady, one single suffering. He had had several cases of dysentery at early stages of pregnancy, one of them very severe, in fact, contemporaneous with it—he should say symptomatic of pregnancy: this would be much aggravated by a bilious temperament, and any affection of the liver.”
On cross-examination the witness explained that “in this country idiopathic dysentery assumed a less severe form than in warm climates—was what is called subacute or chronic, and that the state of the cæcum indicated a case of subacute, not of severe dysentery, of prolonged dysentery, and that it did not necessarily follow that such a case should commence with febrile symptoms.” On re-examination he stated, that “in early pregnancy the dysenteric motions have become bloody, the sign of dysentery which may come on immediately or not; in a day or two in acute dysentery, the result of neglected diarrhœa. Subacute dysentery is frequently the result of neglected diarrhœa, or chronic dysentery—you have acute, subacute, and chronic.”
Mr. James Edmunds, Surgeon to the Royal Maternity Charity, cited a case in his own practice of a woman of about forty years of age, who had been married ten or twelve years, and who in her pregnancy suffered from vomiting, purging, and severe pain in her abdomen, and who, from the post-mortem examination which he made, he was convinced died of dysentery, complicated by vomiting and irritability of the stomach attributable to pregnancy, and purging attributable to dysentery. “Purging,” he said, “was often a symptom at an early stage of pregnancy, and often of impending labour.”
On cross-examination, however, he admitted that when he first attended this woman, when the symptoms first began, she had been pregnant five or six months.
Dr. Tyler Smith, the last medical witness called for the defence, in practice for fifteen years as an accoucheur, said that
“He was acquainted with cases in which excessive vomiting in pregnancy had caused death—where it went on after pregnancy had commenced, sometimes during the whole period, but these were exceptional cases. It would require considerable skill to determine accurately the age of a fœtus, as you may have a case in which it may die and remain in utero without development, though no decomposition takes place. He had known one case in which there was a great amount of vomiting and some amount of purging, in which the friends of the lady could not be brought to believe that her husband was not poisoning her. These symptoms might become so violent as to be mistaken for a case of poisoning; the expression on the face in such cases was that of death by starvation.”
On cross-examination, he admitted that though he had seen cases of death in pregnancy from vomiting conjoined with purging, he believed the vomiting to be the great cause of death, and that ordinarily, if dysentery is excessive, abortion is produced. On re-examination, he said “that in the case of a woman of from forty to forty-five years of age, doses of irritant poison were more likely to procure abortion than idiopathic disease.” To a question by a juryman, he said, “any irritating medicine would tend to keep up dysentery.”
With the evidence of a dentist (Pedley) who had attended the prisoner about the middle of February last, and recommended the use of chlorate of potass for foulness of breath, the evidence for the defence was closed.
