Cross-examined by Mr. Grove.—“I did not see the patient during a severe attack. I have observed in animals that spasms are brought on by touch. That is a very marked symptom. The spasm is like a galvanic shock. The patient was not at all insensible during the time I saw her, and she was able to swallow, but I did not see her during a severe attack. After death we found the lungs very much congested. There was a small quantity of bloody serum found in the pericardium. The muscles of the whole body were dark and soft. There was a decided quantity of effusion in the brain. There was also a quantity of serum tinged with blood in the membranes of the spinal cord. The membranes of the spinal marrow were congested to a considerable extent. We opened the head first, and there was a good deal of blood flowing out. Part of the blood may have flowed from the heart. That might partially empty the heart, and would make it uncertain whether the heart was full or empty at the time of death. I have often examined the hearts of animals poisoned by strychnia. The right side of the heart is generally full. In some cases I think that the symptoms did not appear for an hour after the administration of the poison. I have made the experiments in conjunction with Mr. Nunneley. We have made experiments upon frogs, but they are different in many respects from warm-blooded animals. I have in almost all cases found the strychnia where it was known to have been administered. In one case it was doubtful. We were sure the strychnia had been administered in that case, but we doubted whether it had reached the stomach. There were appearances which might lead one to infer the presence of strychnia, but they were not satisfactory. I have detected strychnia in the stomach nearly two months after death, when decomposition has proceeded to a considerable extent.”
Re-examined by the Attorney-General.—“From half a grain to a grain has been administered to cats, rabbits, and dogs. From one to two grains is quite sufficient to kill a dog.”
Question.—“How does the strychnia act? Is it taken up by the absorbents, and carried into the system?”
Answer.—“I think it acts upon the nerves, but a part may be taken into the blood and act through the blood. We generally examined the stomach of the animals when the poison had been administered internally. Sometimes we examined the skin. The poison found in the stomach would be in excess of that absorbed into the system.”
Question.—“Are you then of opinion that, a portion of the poison being taken into the system and a portion being left in the stomach, the portion taken into the system would produce tetanic symptoms and death?”
Mr. Serjeant Shee objected to a question which suggested a theory.
The Attorney-General.—“What would be the operation of that portion of the poison which is taken into the system?”
Answer.—“It would destroy life.”
Mr. Baron Alderson.—“And yet leave an excess in the stomach?”
