"We take an exception!" said Mr. Bliss, and sat down.

"Now please answer the question," said Mr. Munson, addressing the witness.

"Under the hypothesis presented I should say that the minimum dose must have been three grains."

"That is to say, she must have had three grains, or more?"

"Yes, sir; three grains or more."

"What is a medicinal dose?"

"From a thirty-second of a grain to half a grain, though the latter would be unusual."

"Unusually large you mean?"

"Yes. It would be rarely given."

"Then would you say that three grains would be a lethal dose?"

"It would most probably prove fatal. One sixth of a grain has been known to produce death."

"One sixth of a grain has proven fatal, and, from what you found, you conclude that three grains had been given to this woman?"

"Yes, provided your hypothesis as to the time of administration is correct."

"Oh, we will prove the hypothesis."

"Then I should say that three grains had been administered."

"Three grains or more?"

"Yes, three grains or more."

"You may take the witness," said the a.s.sistant District Attorney, and Mr. Bliss at once began his cross-examination.

"Professor, as an expert toxicologist now, leaving a.n.a.lytical chemistry for awhile, you are familiar with the action of drugs in the human body during life, are you not?"

"Of poisonous drugs. Yes, sir."

"Of poisonous drugs of course. Of opium and its alkaloids especially, is what I mean?"

"Yes, sir. I have studied them minutely."

"Now then in regard to morphine. You said to his Honor, awhile ago, that this drug acts variably upon different individuals. Is it not true that it also acts differently upon the same individual at various times?"

"Yes, sir, that is true."

"And is its action affected by disease?"

"It might be!"

"Supposing that the drug were administered continuously, might it not occur, that instead of being absorbed, the morphine would be retained, stored up as it were, so that the quant.i.ty would acc.u.mulate?"

"Yes, the records contain reports of such cases."

"Well, now, suppose that a patient had some kidney trouble, such as Bright's disease, would not morphine be retained in this way?"

"I have never seen such a case."

"Never seen it! But you have read, or heard of such cases?"

"Yes, sir. That is the claim made by some authorities."

"By good authorities?"

"Yes. Good authorities."

"And these good authorities claim that morphine, administered to one who has Bright's disease, might acc.u.mulate until a poisonous dose were present?"

"Yes, sir!"

Thus was made plain the object of the line of cross-examination that had been followed with Dr. McDougal. It became evident that the defence meant to claim that if Mabel Sloane died from morphine it was because it had been stored up in her system, in consequence of the diseased kidneys. Satisfied with this admission from the prosecution's expert, Mr. Bliss yielded the witness, and he was re-examined by Mr.

Munson.

"Professor," said he, "supposing that in the case of this girl, morphine had been retained in the system, suddenly destroying life because a poisonous quant.i.ty had been thus acc.u.mulated, would you expect to find it, after death, in the stomach?"

"No, sir, I would not."

"How long a time would be required to eliminate it from that organ?"

"Ordinarily it should be eliminated from the system entirely within forty-eight hours. Certainly after that length of time, it should not appear in the stomach."

"And yet in this case you found morphine in the stomach?"

"Yes, sir."

"So that to be there, it must have been administered within two days, and could not have been there as a result of acc.u.mulation beyond that time?"

"I should say that the presence in the stomach proves that the administration must have occurred within two days."

Upon re-cross Mr. Bliss asked a few questions.

"On your original examination, Professor, you said that you found morphine in the intestines and in the stomach. Where did you find the greater quant.i.ty?"

"In the intestines!"

"If, because of kidney disease, morphine were retained in the system, where would you look for it after death?"
