It is optional for the council to admit to registration all such persons as are duly registered in the medical register of Great Britain, or otherwise authorized to practise medicine, surgery, and midwifery in the United Kingdom of Great Britain and Ireland, upon such terms as the council may deem expedient (_ib._, s. 23 [1]). Any person actually practising medicine, surgery, or midwifery, or any of them, in Ontario prior to January 1st, 1850, and who has attended one course of lectures at any recognized medical school, on such proof as the council may require, is entitled to register (_ib._, s. 23 [2]). Any person actually practising medicine, surgery, or midwifery according to the principles of homœopathy before January 1st, 1850, and for the six years preceding March 24th, 1874, in Ontario, may in the discretion of the representatives of the homœopathic system of medicine be registered (_ib._, s. 23 [3]). Any person who possesses any of the qualifications described in Schedule B, dated prior to July 23d, 1870, on the payment of the fee, is entitled to register on producing to the registrar the document conferring or evidencing his qualification or qualifications, or on transmitting by post to the registrar information of his name and address and evidence of the qualification or qualifications in respect whereof he wishes to be registered and of the time or times at which the same was or were attained. No one registered under the acts mentioned in sec. 3 is liable to pay for registration (_ib._, s. 24). Every person wishing to be registered, and not possessed before July 23d, 1870, of one of the qualifications in Schedule B, must present himself for examination as to his knowledge and skill for the efficient practice of his profession before the board of examiners mentioned in sec. 28, and upon passing the examination required and proving to the satisfaction of the board of examiners that he has complied with the rules and regulations of the council, and on payment of such fees as the council may establish, he shall be entitled to register and in virtue of his registration to practise medicine, surgery, and midwifery (_ib._, s. 25). When it appears that there has been established a central examining board similar to that constituted by this act, or an institution duly recognized by the legislature of any of the provinces of the Dominion of Canada as the sole examining body for the purpose of granting certificates of qualification, and wherein the curriculum is equal to that established in Ontario, the holder of such certificate shall, upon due proof, be entitled to registration by the council of Ontario if the same privilege is accorded by such examining board or institution to those holding certificates of Ontario (_ib._, s. 26).
