 morphine was the cause of death. Their cross-examination of our witnesses was suggestive of death from natural causes: from heart disease, a brain tumor, apoplexy, epilepsy, uremia. In fact, the multiplicity of their defences was a great weakness. Gradually they were forced to abandon all but two possible causes of death,—that by morphine poisoning and that by uremic poisoning. This narrowed the issue down to the question, Was it a large dose of morphine that caused death, or was it a latent kidney disease that was superinduced and brought to light in the form of uremic coma by small doses of morphine, such as the one-sixth of a grain admittedly contained in the capsules Harris administered? In one case Harris was guilty; in the other he was innocent.

Helen Potts died in a profound coma. Was it the coma of morphine, or that of kidney disease? Many of the leading authorities in this city had given their convictions in favor of the morphine theory. In reply to those, the defence was able to call a number of young doctors, who have since made famous names for themselves, but who at the time were almost useless as witnesses with the jury because of their comparative inexperience. Mr. Jerome had, however, secured the services of one physician who, of all the others in the country, had perhaps apparently best qualified himself by his writings and thirty years of hospital experience to speak authoritatively upon the subject.
