Examinations for a license are required to be given in at least four convenient places in this State at least four times annually in accordance with the regents’ rules, and exclusively in writing and in English. Each examination is conducted by a regents’ examiner who shall not be one of the medical examiners. At the close of each examination the regents’ examiner in charge is required to deliver the question and answer papers to the board selected by each candidate, or its duly authorized committee, and such board, without unnecessary delay, is required to examine and mark the answers and transmit to the regents an official report stating the standing of each candidate in each branch, his general average, and whether the board recommends that a license be granted. Such report must include the questions and answers and is filed in the public records of the university. If the candidate fails on a first examination, he may, after not less than six months’ further study, have a second examination without fee. If the failure is from illness or other cause satisfactory to the regents they may waive the requirement of six months’ study (_ib._, s. 147). On receiving from a State board an official report that the applicant has successfully passed the examinations and is recommended for license, the regents are required to issue to him, if in their judgment he is duly qualified therefor, a license to practise medicine. The contents and execution of the license are regulated in detail by the act. Applicants examined and licensed by other State examining boards registered by the regents as maintaining standards not lower than those provided by this article, and applicants who matriculated in a New York State medical school before June 5th, 1890, and who shall have received the degree of “M.D.” from a registered medical school before August 1st, 1895, may, without further examination, on the payment of ten dollars to the regents, and on submitting such evidence as they may require, receive from them an indorsement of their license or diploma conferring all the rights and privileges of a regents’ license issued after an examination. If any person whose registration is not legal because of some error, misunderstanding, or unintentional omission shall submit satisfactory proof that he had all the requirements provided by law at the time of his imperfect registration, and was entitled to be legally registered, he may, on the unanimous recommendation of a State board of medical examiners, receive from the regents under seal a certificate of the facts, which may be registered by any county clerk and shall make valid the previous imperfect registration. Before any license is issued, it must be numbered and recorded in a book in the regents’ office, and its number noted in the license. This record in all legal proceedings has the same weight as evidence that is given to a record of conveyances of land (_ib._, s. 148).
