Then the next thing that is said is that the heart in this case was empty. In the animals Mr. Nunneley and Dr. Letheby have operated upon I think the heart has been found full. I do not think that applies to all the cases; I think they make some exceptions; and, as I said at the outset, it is a remarkable fact connected with the history of this particular poison, that you never can rely upon the precise form or order which the symptoms before death and the appearances after it will assume. There are only certain great, leading, marked characteristic features--the collateral incidents are capable of infinite variety. We have here the main marked characteristic features, and we have, what is more, collateral incidents similar to the cases in which the administration of strychnia and the fact that death was caused by it are beyond the possibility of dispute. In the very evidence which has been adduced of two cases of poisoning, Mrs. Smyth’s and the Glasgow girl, in both the heart had been found contracted and emptied; and it is obvious to any one who reflects for a single moment that the question whether the heart shall be found congested or the lungs congested must depend upon the immediate cause of death, and we know that in cases of tetanus death may result from more than one cause. All the muscles of the body are subject to the exciting action of this powerful poison, but no one can tell in what order those muscles will be affected, or where the poisonous influence will put forth the fulness of its power. If it act upon the respiratory muscles, and arrest the play of the lungs, and with it the breathing of atmospheric air, the result will be that the heart will be left full; but if some spasm seizes on the heart, contracting it and expelling from it the blood that it contains, and so produces death, why the result will be that the heart will be found empty, and the other vessels gorged with blood. So that you have never perfect certainty as to how those symptoms will manifest themselves after death; but that is again put forward as if the fact of the heart having been found empty is a conclusive fact against death having in this case taken place from strychnia. Yet those men who came here to make those statements as witnesses under the sanction of scientific authority must have heard both those cases spoken to by the medical gentlemen who examined those two unfortunate patients after death, and who told us that in both cases the heart was found empty. That gets rid of that matter. And so again with regard to the congestion of the brain and other vessels the same observation applies. If instead of being killed by the action of the poison upon the respiratory muscles or by its action upon the heart, death is the result of a long series of paroxysms exhausting the vital power of the victim, then you expect to find the brain and other vessels congested by those series of convulsions and spasms. As death takes place from one or other of those
