3). All examinations shall be in writing; the questions and answers, except in materia medica and therapeutics, must be such as can be answered in common by all schools of practice, and if the applicant intends to practise homœopathy or eclecticism, the member or members of the said board of those schools shall examine the said applicant in materia medica and therapeutics; if the examination is satisfactory, the board shall issue a license entitling the applicant to practise medicine. A license shall not be issued unless the applicant passes an examination satisfactory to all members of the board; the examination papers kept on file by the secretary of the board are _prima facie_ evidence of all matters therein contained; on refusal of the board to issue a license for failure on examination, the applicant may appeal to the governor, who may appoint a medical commission of review of three members, one from each school of medicine, who shall examine the examination papers of the applicant and from them determine whether a license should be issued, and their decision shall be final; if the said committee by unanimous vote reverse the determination of the board, the board shall issue a license; the expenses of the appeal are borne by the applicant (_ib._, s. 4). The board may, by unanimous vote, refuse or revoke a license for chronic and permanent inebriety, the practice of criminal abortion, conviction of a crime involving moral turpitude, or for publicly advertising special ability to treat or cure disease which, in the opinion of the said board, it is impossible to cure. In complaints for violating this section, the accused shall be furnished with a copy of the complaint and given a hearing before the said board in person or by attorney (_ib._, s. 5). A person receiving a license must file it, or a certified copy thereof, with the clerk of the county in which he resides; and in case of removal into another county he must procure from the said clerk a certified copy of the said license, and file it with the clerk in the county to which he shall remove (_ib._, s. 6).
