No person practising physic or surgery, or both, prohibited by the above section from testifying in a professional capacity as a physician or surgeon, shall assume the title of doctor, physician, or surgeon by means of any abbreviation or by the use of any other word or words, letters of the alphabet of the English or any other language, or any device of whatsoever kind, printed, written, or painted, or exhibited in any advertisement, circular, handbill, letter, or other instrument, nor on any card, sign, door, or place whatsoever. PENALTY, EXCEPTIONS.—A violation of this act is a misdemeanor punishable with a fine of from $25 to $100, or imprisonment in a county jail from ten days to sixty days for each offence (s. 1, c. 256, 1881, as amended c. 40, 1882). On complaint in writing under oath before any magistrate or justice of the peace charging the commission of an offence against the provisions of this act in his county, it is the duty of the district attorney to prosecute the offender, and in all such prosecutions the burden of proof shall be upon the defendant to establish his right to use such title under the provisions of this act (_ib._, s. 2). Any person prohibited by sec. 1 from assuming the title of doctor, physician, or surgeon who shall practise or pretend to practise physic or surgery, or both, is not exempted from any, but is liable to all, of the legal penalties and liabilities of malpractice, and ignorance shall be no excuse for a failure to perform or for neglect or unskilfully performing or attempting to perform any of the duties required by law of practising physicians or surgeons. The act does not prevent students from practising under the direction of a qualified preceptor, nor women from practising midwifery, nor veterinarians from practising in their special department (_ib._, s. 3). WYOMING. QUALIFICATION.—No person can lawfully practise medicine, surgery, or obstetrics who has not received a medical education and diploma from some regularly chartered medical school having a _bona fide_ existence when the diploma was granted (R. S., 1887, s. 1,925). Every physician, surgeon, or obstetrician must file for record with the register of deeds of the county in which he is about to practise or where he practises, a copy of his diploma, exhibiting the original, or a certificate from the dean of the medical school of which he is a graduate certifying to his graduation (_ib._, s. 1,926). When filing a copy of his diploma or certificate of graduation, he must be identified as the person named in the paper about to be filed by the affidavit of two citizens of the county, or his affidavit taken before a notary public or commissioner of deeds for the State, which affidavit must be filed in the office of the register of deeds (_ib._, s. 1,927).
