There are no other poisons that I know of that produce convulsions of a tetanic character. The symptoms described which attended this gentleman’s death are not referable to idiopathic or traumatic tetanus. I have never seen a person die from the administration of strychnia, but I have seen a person suffer from the consequences of an overdose. There was the opisthotonos and there was the consciousness perfectly retained. There was also dilation of the pupils, a peculiar convulsion of the muscles of the trunk, and the limbs were stiffened out. Difficulty of breathing is common to both tetanus and to tetanic convulsions from strychnia. In the case of Mr. Cook, I think it is an important distinction that he seems to have been able to swallow sufficiently easy, and there was no rigidity of the muscles of the jaw which is characteristic of tetanus, of disease, or of wound. I think the symptoms in his case, judging from my own experience, were those of tetanus from strychnia. Cross-examined by Mr. GROVE--The proximate effect of tetanus, whether caused by idiopathic or traumatic tetanus, or strychnia, is probably the same on the nerves leading from the spine. The particular affection of the nerves is unknown. In the disorder of convulsions there are cases of very slight affection, others more serious, and so on. I adhere to the opinion given by me in my lectures on “Diseases of the Brain and Nervous System,” that the results of the administration of strychnine exactly imitate the convulsions of tetanus. It does not produce the exact phenomena of the disease in a clinical sense. I have no doubt the peculiar irritation of the nerves in tetanus is identical with the peculiar irritation of the nerves in strychnine poisoning. In traumatic tetanus I do not recollect any instance of the limbs being affected before the jaw. An examination of the spinal cord in tetanic affections shortly after death is of importance. If it were deferred as late as two months, there would be, to a certain extent, a fallacy. There are morbid appearances produced by wounds after death which sometimes simulate diseased conditions before death.
