The medical register shall contain separate lists of the names and addresses of colonial and foreign practitioners, and the provisions of 21 and 22 Vict., c. 90, relating to persons registered and to the medical register, and to offences, shall apply in the case of colonial and foreign practitioners registered under this act so far as may be (_ib._, s. 14). Any registered practitioner on the list of colonial or foreign practitioners who is in possession of or obtains any recognized colonial or foreign medical diploma granted in a British possession or foreign country to which this act applies may cause a description of such diploma to be added to his name in the medical register (_ib._, s. 15). Any registered medical practitioner on the medical register by virtue of English, Scotch, or Irish qualifications, and in possession of a foreign degree in medicine, may cause a description of such foreign degree to be added to his name as an additional title in the medical register, provided he satisfy the general council that he obtained such degree after a proper examination and prior to the passage of this act (_ib._, s. 16). Her Majesty may from time to time, by order in the council, declare that this act be deemed to apply to any British possession or foreign country which in the opinion of Her Majesty affords the registered medical practitioners of the United Kingdom such privileges of practice in the said British possessions or foreign countries as to Her Majesty may seem just; and on and after the day named in such order such British possession or foreign country shall be deemed to be a British possession or foreign country to which this act applies. Her Majesty may also renew or revoke any such order, and upon such revocation such possession or foreign country shall cease to be a possession or country to which this act applies without prejudice to the right of any person whose name has already been entered on the register (_ib._, s. 17). Nothing in the Medical Act of 1858 shall prevent a person holding a medical diploma, entitling him to practise medicine or surgery in a British possession to which this act applies, from holding an appointment as a medical officer in any vessel registered in that possession (_ib._, s. 18). DEFAULT OF GENERAL COUNCIL.—In default of the general council to perform any duty, the privy council may notify their opinion to the general council, and on the failure of the general council to comply with any direction of the privy council, the privy council may themselves give effect to such direction, and for that purpose exercise any power vested in the general council, and of their own motion do anything which they are authorized to do in pursuance of a report or suggestion from the general council (_ib._, s. 19).
