Answer.—“It is exactly what I should expect to arise from a sense of suffocation.”
Question.—“Do you know in your reading of any case in which the symptoms of poisoning by strychnia commenced with beating of the bed clothes?”
Answer.—“There have been only about fifteen cases, and in none of those was the patient seized in bed. Beating of the bed clothes is a symptom which may be exhibited by a person suffering from a sense of suffocation, whether caused by strychnia or other causes. A case has been communicated to me by a friend, in which the patient shook as though with an ague.” [Answer objected to, but allowed as witness had been questioned as to the results of his reading.] “I have known of no case of poisoning by strychnia in which the patient screamed before he was seized. That is common in ordinary convulsions. In cases of poisoning by strychnia the patient screams when the spasms set in; the pain is very severe. I cannot refer to a case in which the patient has spoken freely after the paroxysms had commenced.”
Question.—“Can you refer me to any case in an authentic publication in which the access of the strychnia paroxysm has been delayed so long after the injection of the poison as in the case of Cook on Tuesday night?”
Answer.—“Yes; longer. In my book on Medical Jurisprudence, p. 185, 5th Edition, it is stated that in a case communicated to the Lancet, Aug. 31, 1850, by Mr. Bennett, a grain and a half of strychnia taken by mistake destroyed the life of a healthy female in an hour and a half. None of the symptoms appeared for an hour. There is a case in which the period which elapsed was two hours and a half. A grain and a half is a full, but not a very considerable, dose. In my book on Poisons there is no case in which the paroxysm commenced more than an hour and a half after the injection of the poison. That book is eight years old, and since 1848 cases have occurred. There is a mention of one in which three hours elapsed before the paroxysms occurred.”
Mr. Serjeant Shee then referred to the case, and called attention to the fact that the only statement as to time was that in three hours the patient lost his speech, and was seized with violent convulsions.[51]
Cross-examination continued.—“I know of no other fatal case in which the interval was so long. In that case there was disease of the brain. Referring to the Lancet, I find that in the case to which I referred, as communicated by Dr. Bennett, the strychnia was dissolved in cinnamon water. Being dissolved, one would have expected it to have a more speedy action. The time in which a patient would recover would depend entirely upon the dose of strychnia which had been taken. I do not remember any case in which a patient recovered in three or four hours, but such cases must have occurred. There is one mentioned in my book on Medical Jurisprudence. The patient had taken nux vomica, but its powers depend upon strychnia. In that case the violence of the paroxysms gradually subsided, and the next day, although feeble and exhausted, the patient was able to walk home. The time of the recovery is a point which is not usually stated by medical men. I cannot mention any case in which there was a repetition of the paroxysms after so long an interval as that from Monday to Tuesday night, which occurred in Cook’s case. I do not think that the attack on Tuesday night was the result of anything which had been administered to him on the Monday night. In the cases of four out of five rabbits the rigidity was continued at the time of death and after death. In the other the animal was flaccid at the time of death.”
Question.—“Are you acquainted with this opinion of Dr. Christison, that in these cases rigidity does not come on at the time of death, but comes on shortly afterwards?”
Answer.—“Dr. Christison speaks from his experience, and I from mine.”
Question.—“Did you hear that Dr. Bamford said that when he arrived he found the body of Cook quite straight in bed?”
