1. The rule is not strictly observed in the Coroner’s Court, wherein an enquiry, and not a trial between parties, is held. 2. Formally recorded dying declarations; the medical adviser often hears “the last whisper of life.” 3. Spontaneous and voluntary confessions are sometimes made to medical men. 4. Where the statement in question was part of the proceedings under investigation, thus: _a._ The complaints and natural expressions of a patient as to what he feels: his words aid in deciding the course of treatment. _b._ The natural expressions of a frightened person, who has not had time to concoct a lie: thus after personal injuries, indecent assault, or rape. VI. PRECAUTIONS TO BE OBSERVED UNDER SUSPICIOUS CIRCUMSTANCES; WHICH MAY TERMINATE IN THE CORONER’S COURT, AND NEED MEDICAL EVIDENCE. The primary duty of a medical man is to treat every patient _as a patient_. =1. Chronic or slow poisoning= (including alcoholic). _Cautions._ Try all possible preventive means before announcing the suspicion; do not move until your ground is quite sure: otherwise an action for defamation of character may result. The family medical man must not be misled by the suspicions of weak-minded or alcoholic patients; he must exclude every possibility of an accidental origin of the symptoms. He should know the several personalities of his patient’s families. The symptoms may appear during medical treatment: poison being substituted as “a lingering dram.” If convinced, by repeated examination of the patient’s food and excreta, by his symptoms, and by the conduct of the suspected person, that the influence of poison is at work, let it be understood by the patient’s friends that you are not satisfied with the progress made: suggest the possibility of an accidental poisoning. Do not, at present, associate any name as the culprit; suggest a consultation with a medical friend. Have the patient placed under the constant care of day and night nurses, who, although being instructed to administer personally all food and medicine, need not know at first your suspicions. If the line of defence is circumvented, or is impossible, have the victim removed to a nursing home, or to a hospital. Your suspicions, without mentioning any name, should be told _viva voce_ to the relatives of the poisoned person, to his solicitor, or to the suspect himself. If this course is futile, the name can be introduced in the information given to these persons, to the patient himself, or, finally, to a magistrate, or to the police. Should the victim die, the Coroner should be asked to order an expert toxicological examination of the body of the deceased. =2. Threatened suicide.= “There is a rule of life far higher than professional etiquette—a duty that every right-minded man owes his neighbour—to prevent the destruction of human life.”
