The affidavit of the applicant and holder of a diploma that he is the person therein named, and is the lawful possessor thereof, is necessary to verify the same, with such other testimony as the board may require. Diplomas and accompanying affidavits may be presented in person or by proxy. If a diploma is found genuine and in possession of the person to whom it was issued, the board, on payment of the fee to its secretary, must issue a certificate. If a diploma is found fraudulent or not lawfully in possession of the holder or owner, the person presenting it, or holding or claiming possession, is guilty of a misdemeanor, punishable with a fine of from $20 to $100 (_ib._, s. 3). The certificate must be recorded in the office of the county recorder in the county wherein the holder resides, within sixty days after its date. Should he remove from one county to another to practise medicine, surgery, or obstetrics, his certificate must be recorded in the county to which he removes. The recorder must indorse upon the certificate the date of record (_ib._, s. 4). Any one failing to pass is entitled to a second examination within twelve months without a fee; any applicant for examination, by notice in writing to the secretary of the board, is entitled to examination within three months from the time of notice, and the failure to give such opportunity entitles such applicant to practise without a certificate until the next regular meeting of the board. The board may issue certificates to persons who, upon application, present a certificate of having passed a satisfactory examination before any other State board of medical examiners, upon the payment of the fee provided in sec. 3 (_ib._, s. 6, as amended c. 66, Laws 1888, 22 Gen. Assembly). The board may refuse a certificate to a person who has been convicted of felony committed in the practice of his profession, or in connection therewith; or may revoke for like cause, or for palpable evidence of incompetency, and such refusal or revocation prohibits such person from practising medicine, surgery, or obstetrics, and can only be made with the affirmative vote of at least five physicians of the State board, in which must be included one or more members of the different schools of medicine represented in the said board; the standing of a legally chartered medical college from which a diploma may be presented must not be questioned except by a like vote (_ib._, s. 7).
