Mr. THOMAS NUNNELEY, examined by Mr. GROVE--I am a Fellow of the College of Surgeons, Professor of Surgery at the Leeds School of Medicine, and a member of several foreign and English scientific societies. I have been in practice between twenty and thirty years. I have seen cases of both traumatic and idiopathic tetanus. One of the four cases of idiopathic tetanus I have seen did not commence with the symptoms of lockjaw, nor did lockjaw occur sufficiently to prevent swallowing during the whole period of illness. I have been present during the evidence given here as to the symptoms of Mr. Cook. I had previously read the portions of the depositions as to the scientific and medical part of the case. Judging from the symptoms as described, and confining myself to the evidence as to the scientific part of the case, my opinion is that Mr. Cook died from some convulsive disease. I found that upon the difference of the symptoms described in the deposition and on the evidence before the Court. LORD CAMPBELL--This is not satisfactory; we cannot ask witnesses what faith they give to the evidence of the witnesses as contrasted with the depositions. This witness’s opinion ought to be founded on the _viva voce_ evidence of the witnesses given during the trial. Examination resumed--The previous state of health of Mr. Cook had some effect on my judgment. State your own grounds in your own way for that opinion?--If I take the evidence which has occurred in Court-- By LORD CAMPBELL--The evidence of the symptoms of John Parsons Cook as stated by the witnesses?--Not merely the symptoms, but the general state of health. But we have nothing to do with that. The witness should give his opinion on the symptoms described, and then state what influences the other facts may have had on his mind. By Mr. SERJEANT SHEE--Do you remember the accounts that were given of what was said or supposed to be syphilitic sores? The ATTORNEY-GENERAL--But there was no such thing said. Mr. BARON ALDERSON--Supposing a person had syphilitic sores, what would you say then? That is the proper way of putting it. LORD CAMPBELL--We must take it that medical men are not to be substituted for the jury. [Sidenote: T. Nunneley] Mr. JUSTICE CRESWELL--If I were to suggest a mode of meeting the thing it would be this--let the gentleman describe what he assumes to be the state of the deceased’s health at the time, then the Attorney-General may say he is not justified in assuming.
