Witness. "I do not swear to that."
Counsel. "What did she die of?"
Witness. "I don't swear what she died of."
Counsel. "I understood you to say that in your opinion the symptoms of morphine could not be sworn to with positiveness. Is that correct?"
Witness. "I don't think they can, with positiveness."
Counsel. "Do you wish to go out to the world as saying that you have never diagnosed a case of morphine poisoning excepting when you had an autopsy to exclude kidney disease?"
Witness. "I do not. I have not said so."
Counsel. "Then you have diagnosed a case on the symptoms alone, yes? or no? I want a categorical answer."
Witness (sparring). "I would refuse to answer that question categorically; the word 'diagnosed' is used with two different meanings. One has to make what is known as a 'working diagnosis' when he is called to a case, not a positive diagnosis."
Counsel. "When was your last case of opium or morphine poisoning?"
