INTRODUCTION
Medical Jurisprudence, Forensic Medicine, or Legal Medicine are terms for that science which teaches the application of the knowledge of all branches of medical and surgical science and art to the solution of every question connected with the conservation of the species and the administration of Justice. We find traces of this science in the Jewish law; among the Egyptians, according to Plutarch; and even among the Romans as early as the times of Numa Pompilius. Among German writers the term State Medicine includes both Medical Jurisprudence and Medical Police, Public Health, or Sanitary Science.
The special knowledge requisite to the Medical Jurist differs in many ways from that requisite for the art of healing the sick. The majority of medical students and practitioners may consider a simple exercise of common sense in the application of their general professional knowledge to the elucidation of problems of medico-legal import all that is requisite, and that no special training is necessary for the purpose. They may hope that it may never fall to their lot to be called upon to act in the capacity of medical jurists. It may occur, however, to any medical practitioner at any time of his professional career that his services be requisitioned by law for the purpose of elucidating problems of such a nature as will demand from him thought and judgment quite apart from those he exercises in the ordinary course of his medical and surgical practice. From such a requisition he has no escape; he cannot shift his responsibility to another, and it behoves him, therefore, to acquire a knowledge of Forensic Medicine, in order to guide him, when so called upon, to give such evidence as will enable a judge and jury to arrive at a just conclusion. The relations of all medical practitioners to the State are twofold—first, as healers of disease, and secondly, both as guardians of the innocent against unfounded criminal charges and aids towards the detection and punishment of crime.
