The next witness is Mr. John Bainbridge. The object of this witness’s evidence seems to be to induce you to believe that this was a case of epilepsy, and from the symptoms you will say whether you can come to that conclusion.
The next witness is Mr. Edward Steady. The case referred to by this witness seems to be a case of traumatic tetanus; and you will say, if it were idiopathic, whether the course of it in the slightest degree resembles the symptoms of Cook, the deceased.
The next witness is Dr. Robinson. Now, gentlemen, you have this respectable physician, who gives an account from which you are called to infer that Cook’s case was a case of epilepsy. He says he should only take it to be epilepsy in the absence of evidence of strychnia being administered. He says that all the symptoms described by Jones on the Tuesday night are consistent with strychnia; and, with regard to epilepsy, he says in no case where epilepsy had existed would it cause death without a loss of consciousness. Cook, you will remember, remained conscious to the last, and you will say whether, upon the evidence that is laid before you, there was or was not a bending of the body, which is characteristic of tetanus, and what the witnesses have described as being inconsistent with epilepsy.
The next witness is Dr. Richardson, who now brings in for the first time angina pectoris as a disease of which it may be presumed Cook died. Now, gentlemen, you have to attend to this case; the witness, who seems most highly respectable, says this case being detailed by him, the symptoms were consistent with strychnia, and that, if he had known as much of strychnia then as he does now, he would have made an analysis to see whether strychnia was in the body. The great question that I propounded for your consideration was whether Cook’s symptoms were consistent with strychnia, and, if they were not, then the conclusion would be in favour of the prisoner; but if they were consistent with strychnia, then you are not upon that alone to find a verdict of guilty against him; but you are to consider the other evidence and see whether the death arose from strychnia or not. Dr. Wrightson is recalled, and he says that, in his opinion, when strychnia is entirely absorbed in the system it is diffused equally throughout the entire system. Dr. Wrightson is a philosopher, and, as a man of science, he speaks with caution, and you have heard his evidence. He says that if the minimum dose were taken to destroy life, and then a long interval elapsed between the taking of the poison and death, the more complete would be the absorption, and the less chance there would be of finding it in the stomach.
