(3.) Any person who, on the appointed day, is a member representing an existing Irish constituency in the House of Commons shall, on giving his written assent to the Lord Lieutenant, become a member of the second order of the Irish Legislative Body as if he had been elected by the constituency which he was representing in the House of Commons. Each of the members for the city of Cork, on the said day, may elect for which of the divisions of that city he wishes to be deemed to have been elected. (4.) If any member does not give such written assent within _one month_ after the appointed day, his place shall be filled by election in the same manner and at the same time as if he had assented and vacated his office by death. (5.) If the same person is elected to both orders, he shall, within _seven days_ after the meeting of the Legislative Body, or if the Body is sitting at the time of the election, within _seven days_ after the election, elect in which order he will serve, and his membership of the other order shall be void and be filled by a fresh election. (6.) Notwithstanding anything in this Act, it shall be lawful for the Legislature of Ireland at any time to pass an Act enabling the Royal University of Ireland to return not more than two members to the second order of the Irish Legislative Body in addition to the number of members above mentioned. (7.) Notwithstanding anything in this Act, it shall be lawful for the Irish Legislature, after the first dissolution of the Legislative Body which occurs, to alter the constitution or election of the second order of that body, due regard being had in the distribution of members to the population of the constituencies; provided that no alteration shall be made in the number of such order. Clauses 12 to 20 are the Finance Clauses, which are dealt with at the end of this Appendix. _Police._ 21.

(_b._) The Royal Irish Constabulary shall, while that force subsists, continue and be subject as heretofore to the control of the Lord Lieutenant as representing Her Majesty. (_c._) The Irish Legislature may provide for the establishment and maintenance of a police force in counties and boroughs in Ireland under the control of local authorities, and arrangements may be made between the Treasury and the Irish Government for the establishment and maintenance of police reserves.
