The city of Dublin has seldom presented a scene of more general joy than when the Prince of Wales opened the International Exhibition, on the 9th of May, 1865. The weather was superb, the loyal demonstrations in the streets were enthusiastic, and the great Hall where the opening ceremony took place, decorated with the flag of all nations, was densely crowded with the most distinguished assembly that Ireland could bring to welcome the heir of the throne, and the representative of the Queen. There were no disloyal feelings nor discordant sounds in the Palace that day. The Duke of Leinster, the Earl of Rosse, and the highest and most distinguished of the nobles of Ireland were there. The Lord Mayor and Corporation of the City appeared in their civic robes. The Mayors of Cork and Waterford and Londonderry walked together; and the Lord Mayors of London and York, and the Lord Provost of Edinburgh, with many official personages, joined in the procession. When His Royal Highness took his place in the chair of State, the orchestra, 1000 strong, performed the National Anthem, and 10,000 voices sent up their loyal cheers at its conclusion. The Duke of Leinster read the address of the Committee, to which the Prince replied:-- "My Lords and Gentlemen,--I thank you for your address.

The example of my lamented and beloved parent will, I trust, ever be present to my mind as a stimulus in the encouragement of every work tending to advance international prosperity, and to develope the powers and resources of our own country. The cultivation of the fine arts, in itself so powerful an auxiliary in the civilization and refinement of the human race, has been an important object in these Exhibitions, and seems already to have produced most satisfactory results. Believe me very sensible of your kind wishes on behalf of the Princess of Wales. Her regret at being unable to accompany me equals my own, and you may rely upon her anxiety to come among you, assured of the welcome she will receive." Then from the grand organ and choir rose the ever impressive music of the Hundredth Psalm, the most Catholic of all strains of praise and thanksgiving. At its close there was another address, giving an account of the origin and history of the Exhibition. A copy of the Catalogue, and the key of the building, having been presented to the Prince, the organ and orchestra pealed forth Handel's Coronation Anthem. Then came another address, presented by the Lord Mayor and the Corporation of Dublin, in their civic robes. This was read and handed to His Royal Highness, who thus replied:--
