“It is a complaint made by coroners, magistrates and judges, that medical gentlemen are often reluctant in the performance of the offices, required from them as citizens qualified by professional knowledge, to aid the execution of public justice. These offices, it must be confessed, are generally painful, always inconvenient, and occasionally an interruption to business of a nature not to be easily appreciated or compensated.” (Percival T. Medical Ethics or a Code of Institutes and Precepts adapted to the Professional Conduct of Physicians and Surgeons, Manchester, S. Russell, 1803.)
