BOARD OF EXAMINERS.—The governor appoints a board of medical examiners of nine members, no one of whom can be a member of a college or university having a medical department, and two of whom must be homœopathic physicians (Act 1887, c. 9, s. 1). QUALIFICATION.—Persons commencing the practice of medicine and surgery in any of its branches must apply to the board for a license, and at the time and place designated by the board, or at a regular meeting, submit to an examination in anatomy, physiology, chemistry, histology, materia medica, therapeutics, preventive medicines, practice of medicine, surgery, obstetrics, diseases of women and children, of the nervous system, of the eye and ear, medical jurisprudence, and such other branches as the board deems advisable, and present evidence of having attended three courses of lectures of at least six months each; the examination must be scientific and practical, but of sufficient severity to test the candidate’s fitness to practise medicine and surgery. When desired, the examination may be conducted in the presence of the dean of any medical school or the president of any medical society of this State. After examination, the board must grant, with the consent of at least seven members, a license to practise medicine and surgery, which may be refused or revoked for unprofessional, dishonorable, or immoral conduct; and in case of refusal or revocation, the applicant may appeal to the governor (_ib._, s. 3).
