Witness. "I can't remember which was the last."
Counsel (seeing an opening). "I don't want the name of the patient. Give me the date approximately, that is, the year—but under oath."
Witness. "I think the last was some years ago."
Counsel. "How many years ago?"
Witness (hesitating). "It may be eight or ten years ago."
Counsel. "Was it a case of death from morphine poisoning?"
Witness. "Yes, sir."
Counsel. "Was there an autopsy?"
Witness. "No, sir."
Counsel. "How did you know it was a death from morphine, if, as you said before, such symptoms cannot be distinguished?"
