Then, gentlemen, comes the more direct evidence that the prisoner at the bar, if you believe the witnesses, procured this very poison on the Monday and on the Tuesday—3 grains, I think, on the Monday, and 6 on the Tuesday. For what purpose was that obtained? The evidence of the witness who swears to the poison being obtained on the Monday is impeached, but no impeachment rests upon the evidence of the witness who swears to the poison being sold by him on the Tuesday to the prisoner at the bar. You have no account of that poison; what was the intention with which it was purchased, and what was the application of it, you are to infer. Then, gentlemen, it is impossible that you should not pay attention to the conduct of the prisoner at the bar, and there are some instances of his conduct which you will say whether they belong to what might be expected from an innocent or a guilty man. He was eager to have the body fastened down in the coffin. Then, with regard to the betting book, there is certainly evidence from which you may infer that he did get possession of the betting book, that he abstracted it and concealed it. Then, gentlemen, you must not omit his conduct in trying to bribe the postboy to overturn the carriage in which the jar was being conveyed, to be analysed in London, and from which evidence might be obtained of his guilt. Again, you find him tampering with the postmaster, and procuring from the postmaster the opening of a letter from Dr. Taylor, who had been examining the contents of the jar, to Mr. Gardner, the attorney employed upon the part of Mr. Stevens. And then, gentlemen, you have tampering with the coroner, and trying to induce him to procure a verdict from the coroner’s jury which would amount to an acquittal. These are serious matters for your consideration, but you, and you alone, will say what inference is to be drawn from them. If not answered, they certainly present a serious case for your consideration. It is for you to say whether the answer is satisfactory. Either you may be of opinion that the case on the part of the prosecution is insufficient, or you may be of opinion that the answer to it is satisfactory.

Then, gentlemen, that answer consists of two parts—first, of the medical evidence, and, secondly, of the evidence of facts. With regard to the medical evidence, I must say that there were examined on the part of the prisoner a number of gentlemen of high honour and solid integrity and proved scientific knowledge, who came here only to speak the truth and assist in the administration of justice. You may be of opinion that others came whose object was to procure an acquittal of the prisoner. Gentlemen, it is material, in the due administration of justice, that a witness should not be turned into an advocate, any more than an advocate should be turned into a witness. It is for you to say whether some of those who were called on the part of the prisoner did not belong to the category which I described as witnesses becoming advocates.

Gentlemen, the first witness on the part of the prisoner was Mr. Thomas Nunneley. (The learned judge read the evidence of Mr. Nunneley and the documents therein referred to.) You will recollect what he says, and you will form your opinion as to the weight that is to be given to it. He certainly seemed to me to give his evidence in a manner not quite becoming a witness in a Court of justice, but you will give all attention to the facts to which he refers in the evidence he gave. He differs very materially in his general opinion from several of the witnesses who were examined on the part of the prosecution. He speaks of there being an extraordinary rigidity of the body after death, when there has been a death of this description, with other symptoms, and he attaches considerable importance to the heart being empty, but you will say what weight ought to be attached to his opinion.

Lord Campbell

Mr. William Herapath is then called. (The examination-in-chief of Mr. Herapath was read.) He seems to differ from Mr. Nunneley with respect to the rigidity produced by this poison. Now, gentlemen, Mr. Herapath is a very skilful chemist, and I have no doubt he spoke sincerely what he thought, and what was his opinion? That when there has been death by strychnia, strychnia ought to be discovered; but it seems he intimated an opinion on this very case of Cook that there might have been strychnia, and that Dr. Taylor did not use the proper means to detect it. Now, the only evidence that we have in this case that there was not strychnia is the analysis by Dr. Taylor and Dr. Rees that they did not discover it. As I before pointed out to you, in two other cases in which there certainly had been poisoning by strychnia the result was the same—they could not discover it.

Then the next witness is Mr. Rogers. Now, this is a gentleman whom there seems no reason to doubt; there seems no reason to doubt the facts that he stated, and that he does sincerely entertain the opinion that he expresses; and, according to his evidence, where there has been strychnia mixed with impure matter, it may be expected that it would be detected by skilful experimentalists, and by using the proper tests. Then Dr. Letheby is called; he is the medical officer of health to the city of London and of the London Hospital. I doubt not that Dr. Letheby speaks sincerely, and according to his experience and opinion, but he does say truly that cases vary very much, and that there may be cases which he calls “exceptional,” alluding to the case of the lady at Romsey; and it may probably be the fair result that enough of this disease is not known to be aware of all its varieties, and that any peculiarity that may arise where there is strong probability of strychnia having been administered would not be anything like conclusive evidence to rebut that result.

Then Mr. Robert Gray is examined. Now, gentlemen, here you have a case of what is called idiopathic tetanus; but you are to say whether from this you can infer that the illness of Mr. Cook was idiopathic tetanus. The great weight of evidence seems to me to show that it was not idiopathic any more than traumatic tetanus; but that whatever form of disease it might be, it would not be idiopathic tetanus; and you will find that the symptoms vary most materially in their appearance from the case that is here detailed in the duration as well as the rest of the course of events.

Lord Campbell

The next witness that was called was Mr. Brown Ross. Now, gentlemen, I do not know for what purpose the case alluded to by Mr. Ross was brought before you, unless to lead to an inference that Mr. Cook’s was a case of tetanus of the same sort with this which is here described, because this was tetanus; and I suppose it was intended that you are to infer that Mr. Cook’s was of the same description; but whether you call it idiopathic or traumatic, it was a case of tetanus—was directly to be ascribed to wounds which were upon his body, and which are here described. No such wounds were upon the body of Mr. Cook; and other witnesses who were examined on the part of the defence say that this was not a case of tetanus at all; but then, even in this case that has been described, you see there were the symptoms so nearly approaching those of strychnia that strychnia was suspected, but there was no ground for it; and in the case described there was no ground for supposing strychnia could by possibility be the cause of death.
