Noble was convicted on an indictment *3charging that he in Suwannee County, Florida, practiced dentistry and dental surgery in that he did do and perform dental work for a named person, and “had not at the time he performed said dental work * * obtained and had recorded a certificate from the Florida State Board of Dental Examiners, or any of its members, as required by the laws of said State, contrary to the form of the statute.” On writ of error it is contended that the statute requiring one who practices dentistry to have a certificate from the State Board, of Dental Examiners or one of its members, is unconstitutional; and that the indictment is defective. The statute is as follows: “Any person who shall practice dentistry or dental surgery in this State within the meaning of this Act without having first obtained and had re'corded a certificate from the Florida State Board of Dental Examiners, or its members, or who violates any of the provisions of this Act, the punishment for which he is not herein specifically provided for, shall be deemed guilty as a misdemeanor and upon conviction thereof shall be punished by a fine of not more than one thousand dollars or imprisonment in the county jail not more than twelve months, or by both such fine and imprisonment, in the discretion of the court. Sec. 10, Chap. 6192, Acts of 1911. See also Sec. 3618 Gen. Stats, of 1906.

It is argued that the statute violates the constitutional expression that “all men are equal before the law,” in that it makes it a crime to engage in the practice of dentistry before obtaining a certificate from a State board, and in that the statute permits regularly licensed physicians- to extract teeth. The organic declaration that “all men are equal before the law” may be regarded as a guarantee that all persons shall have equal consideration and protection of the law for the maintenance and security of *4the rights to which they are legally entitled. The exercise of the police power of the State necessarily involves appropriate discriminations; and the fundamental law only requires that such discriminations shall not be arbitrarily unjust or oppressive as they affect the rights of persons. .

The legislature may regulate some occupations and not regulate others, when private rights secured by the Constitution are not thereby invaded and the regulations that are provided operate with substantial fairness upon practically all persons similarly situated, so that the governmental authority be not arbitrarily exercised to injure the substantial rights of or to oppress any person. See Davis v. Florida Power Co., 64 Fla. 246, 60 South. Rep. 759. Legislative authority to regulate intrastate occupations is continuous and is subject to unlimited division of application when organic provisions are not violated. Classifications of persons in legislative regulations may be on any practical substantial basis that has relation to the subject regulated and that is not purely arbitrary and essentially unjust in its operation upon the rights of persons. See Butler v. Perry, and Dutton Phos. Co. v. Priest, decided at this term. If the organic declaration that “all men are equal before the law” is given the force of a guar antee of equal protection of the laws, it is not violated when a legislative regulation within the police power of the State is made applicable to all persons as a class who are similarly situated and conditioned with reference to the regulation, and the classification is not purely arbitrary. Ex parte Whitley, 144 Cal 167, 77 Pac. Rep. 879, 1 Ann. Cas. 13; Dent v. State of West Virginia, 129 U. S. 114, 9 Sup. Ct. Rep. 231. Whether the State has regulated other occupations is not material in determining the validity of this regulation. The statute is applicable to any per*5son who shall practice dentistry or dental surgery in this State, thus making it operate alike on all persons who shall engage in the particular occupation. It does not impose unusual or unnecessary restrictions upon lawful occupations, or prescribe arbitrarily unreasonable conditions. In permitting licensed physicians and surgeons to extract teeth the statute merely makes definite the classes of persons designed to be affected by its operation. There is no feature of an ex post facto law in the statutes here involved. See State v. Chapman, 69 N. J. L. 464, 55 Atl. Rep. 94; In re Thompson, 36 Wash. 377, 78 Pac. Rep. 899. No violation of the obligation of a contract between the accused and the State with reference to the practice of dentistry appears. It was not shown at the trial in defense of the criminal charge, that the accused was legally qualified to practice dentistry in this State before the enactment of the present law, and consequently was expressly not subject to the statute.

Evidence offered in support of a motion for a new trial, that the accused had for ten or twelve years been an actual practitioner of dentistry in this State, could not then be received to show and did not show that the accused was “legally qualified” to practice dentistry in this State.

The indictment alleges all the essentials of the statutory offense and is not so framed as to mislead the accused, or to embarass him in the preparation of his defense, or to expose him to another prosecution for the same offense, therefore it is not fatally or essentially defective. Secs. 3961-2 Gen. Stats, of 1906; Johnson v. State, 58 Fla. 68, 50 South. Rep. 529. It was not necessary for the indictment to charge that the accuse^ did not have a temporary certificate from a single member of the Board, since it is expressly charged that he’had not obtained and had re*6corded a certificate from the Board “or any of its members.”

In the motion for new trial it is. stated that the court erred in not asking certain questions of jurors; but as there is no basis for this in the bill of exceptions it cannot be considered here. Grounds of a motion for new trial are not self supporting. Smith v. State, 57 Fla. 24, 48 South. Rep. 744.

The contention that the statute is contrary to public policy is unavailing since the legislature declares the public policy of the State in enacting the statute. Courts do not consider the reasonableness of a statute when passing upon its validity, unless it is clear that such asserted unreasonableness violates the fundamental rights of the party complaining of it. In this case it is clear that no fundamental right of the accused has been violated by the operation of the statute or by the procedure resulting in his conviction.

The judgment is affirmed.
