(Aftеr stating the foregoing facts.) All of the grounds of demurrer are not set out for the reason that, under the view we take of this case, the ruling on the general demurrer is controlling. Neither is the entire act here set out, for it is only sections 1, 2, and 3 thereof which are under attack, and which the plaintiffs insist render the entire act unconstitutional and void.
Previous to the passage of the act now'under attack, the entire law relating to dental hygienists, their qualifications, examination, etc., was contained in the Code, § 84-1009. 'It is alleged in the petition thаt, acting under the authority of this Code section, the Board of Dental Examiners had adopted a rule which provided that, “On and after July 1, 1941, all applicants will be required to be graduates of a duly incorporated and accredited Dental Hygiene School of nоt less than 9 months’ course of instruction to be acceptable for examination. The Dental Hygiene diploma must be presented to the Board at the first session of the examination”.
Section 1 of the act now before us quotes the above-mentioned section of the Code, and specifically repeals it in its entirety.
Section 2 of the act, in substance, prohibits any person from practicing as a dental hygienist in Georgia “until such person has passed a written and a clinical examination conducted by the Boаrd of Dental Examiners of Georgia”; prescribes a, fee *54 for the examination, and provides that “The said Board of Dental Examiners shall issue licenses and license certificates as. dental hygienists to those persons who have passed said examination in a manner satisfactory to the said Board, which license-certificate shall be posted and displayed in the place in which, said hygienist is employed.”
Section 3 of the act is as follows: “That no person shall be-entitled to, or be issued, such license and license certificate as set out in Section 1 of this Act, unless such person shall be at least 19 years of age, of good moral character, and a graduate-of a school or college for dental hygienists recognized by the Board of Dental Examiners, which schоol conducts a course consisting of not less than one academic year for dental hygienists. Provided, however, that this section shall not apply to those persons, bona fide citizens of the State of Georgia, who, at the time of the passage of this Act are actually employed by, or who have within the past two years have been actually employed by, and performing the duties of a dental hygienist for, a licensed dentist, and who have been so employed and performing such duties for a period of two years preceding the-passage of this Act, and who, within two years from the passage of this Act, or until such time as a school or college for dental hygienists recognized by the Board of Dental Examiners is established in the State of Georgia, present themselves to the-Board of Dental Examiners for a practical examination, and who present to the said Board satisfactory evidence of meeting with the requirements of this proviso.”
Section 4 prohibits dental hygienists from engaging in the practice of dentistry, specifies the рarticular kind of work they may perform; and requires that their work be done only under the supervision of a licensed dentist.
It is insisted by counsel for the plaintiffs that because section 3 of the act provides “That no person shall be entitled to, or be issued, such license and license certificate as set out in section 1 of this act,” sections 1 and 3 of the act are “wholly irreconcilable, discriminatory, ambiguous and unenforcible,” and are “unintelligible, conflicting, and meaningless.” Should such construction be given to the act? It is true that to сonstrue literally that portion of section 3 which refers to section 1 *55 would be to render the act uncertain, ambiguous, and possibly “unintelligible, conflicting, and meaningless.” But 'such a construction of a legislative act is to be avoided if it is at all possible to do so. The сardinal' rule for the construction of statutes is to try to ascertain the intent of the legislature. By referring to the law as it existed prior to the passage of the act under consideration, and the rule adopted by the Board of Dental Examiners which limited those who сould apply for examination and licensing as dental hygienists to those persons only who were “graduates of a duly incorporated and accredited Dental Hygiene School of not less than 9 months’ course of instruction,” and requiring the'diploma from such schoоl to be presented to the board at the first session of the examination, and then to the provision of section 3 of said act, it is clear that one of the main purposes of the legislature in enacting the present law was to enlarge the class of pеrsons eligible to apply for examination and licensing as dental hygienists, by taking in not only graduates of schools as provided in the first portion of section 3, which conforms to the law and the rule of the board as they previously existed, but also those persons who are specified in the proviso of section 3, viz., “bona fide citizens of the State of Georgia, who, at the time of the passage of this Act are actually employed by, or who have within the past two years have been actually employed by, and performing thе duties of a dental hygienist for, a licensed dentist, and who have been so employed and performing such duties for a period of two years preceding the passage of this Act, and who, within two years from the passage of this Act, or until such time as a school or сollege for dental hygienists recognized by the Board of Dental Examiners is established in the State of Georgia, present themselves to the Board of Dental Examiners for a practical examination, and who present to the said Board satisfactory evidence of meeting with the requirements of this proviso.”
It is thus manifest that the reference in section 3 to section “1” of the act is purely a clerical error, and that the reference there is to that section of the act numbered 2, which is the first enacting clause, and not to the section numbered 1, which is a repealing clause of the former law only. To so construe the act would

prevent its nullification and give to it meaning and purpose, and this the court should do, for in

It is contended by counsel for the plaintiffs in error that the act under consideration is violative of the equal-protection and due-process clauses of the Federal and State Constitutions, as being discriminatory in that the act requires “college-trained applicants for license to take both a theoretical (written) examination and a practical (clinical) examination; whereas, applicants who had worked in a dentist’s office would only be required to take a practical (clinical) examination, without a written theoretical examination.” With this contention we do not agree. Section 2 of the act provides: “That no person shall practice as a dental hygienist in the State of Georgia until such person has passed a written and a clinical examination conducted by the Board of Dental Examiners of Georgia,” and that said board “shall issue licenses and license certifiсates as dental hygienists to those persons who have passed said examination in a manner satisfactory to the said Board.” The proviso of .section 3 of the act requires that the applicants under the terms thereof shall present themselves to the Bоard of Dental Examiners “for a practical examination,”
*57
and shall present to the board satisfactory evidence of meeting the other requirements of the proviso. Counsel insist that the term “written examination,” should be held to mean only a theoretical еxamination, and that the term “clinical examination” is synonymous with and means only a “practical examination.” This appears to be a strained construction of the act. Section, 2 is plain and unequivocal that no person shall practice as a dеntal hygienist in this State until such person has passed “a written and a clinical examination” in a manner satisfactory to the board. The requirements of the proviso of section 3, that applicants thereunder shall present themselves to the board for “a practical examination,” do not undertake directly or indirectly to modify or limit the requirements that all applicants shall pass a written and a clinical examination. The word “practical” is defined by Webster as “capable of applying knowledge or theory to practice.” A practical examination would thus cover both theory and practice, and comprehend both a theoretical and clinical examination, and section 2 requires all examinations to be written and clinical. As thus construed, the act is not violative of the equal-protection clauses of the State and Federal Constitutions as requiring one kind of examination for one class of applicants and a different kind of examination for another class, and it does not discriminate against eithеr class of applicants, but applies equally to all.

Nor is the act here under consideration violative of article 3, section 7, paragraph 8 of the Constitution of Georgia (Code, Ann., § 2-1908), providing that “No lаw shall pass which refers to more than one subject-matter, or contains matter different from what is expressed in the title thereof,” as contended by the plaintiffs, “in that the title in part reads, ‘to provide for the licensing of dental hygienists; to provide for examination of applicants for such licensing; to provide for the qualifications of applicants/ although the body of the act attempts to do the opposite of the things stated in the quoted portion of said title.” If this attack be sufficiently definite to raise any question fоr determination by this court

Under the foregoing rulings, the act under consideration was not subject to the attacks made thereon, and the petition as amended failed to state a cause of action. The trial court did not err in sustaining the general demurrer and in dismissing the petition and restraining order previously granted.
Judgment affirmed.
