Philip, at eight, set off for Carlton House in his uniform, as he is to attend the Regent to a Review in Hyde Park at ten, at which hour we go to Mr Macdonald's to see it. Afterwards he will attend the Prince to the House of Lords, and at Night to a great Ball which the Members of White's Club give to the Royals. To-morrow they all go to Portsmouth where a Naval Review is expected, tho' it has been said that it cannot take place owing to many of the Ships having been sent for the Russian troops which are to pass thro' this country on their way home. From Portsmouth the Emperor and the Duchess of Oldenburg go away. The King of Prussia I understand remains some time longer. Ever since the Crowned Heads arrived, London has been mad, & as full again as ever I knew it. Where all the people are lodged I cannot imagine. The streets are full day and night watching the Royals, who see everything and therefore are always upon the move. The King of Prussia walked quietly into St George's Church yesterday and asked for the Duke of Devonshire's pew. They have all been at Oxford where the Prince was with them and was received with great applause. Since I began my letter I have been some hours at Mrs Macdonald's to see a Review in the Park where the Regent and the Crowned Heads attended. The day is beautiful and the scene was very fine, for there were thousands of spectators on foot, as horses and carriages were not admitted into the Park. I was not near enough to distinguish Philip & he has not yet returned.... I have been interrupted again. Philip is to go with the Prince to- morrow to Portsmouth which he likes the idea of extremely. He has been much entertained with the duty of to-day.... After all, the Regent did not go to the House of Lords and the Emperor does not leave London to-day, therefore Philip will have a little rest after the fatigues of yesterday, for he did not get home from the ball till between five and six, and is now asleep. To console London for the termination of such a round of dissipation, on July 1st White's Club gave a magnificent masquerade at Burlington House in honour of the Duke of Wellington, to which the Stanhopes went with their friends, the Kinnairds. Nearly two thousand persons were accommodated in the temporary room which was erected for supper, and the costumes were remarkable for their magnificence, save possibly that of Byron, who was clad, sombrely but effectively, in the dark flowing robes of a monk. A guest of gayer, if less dignified appearance, was Sir Lumley Skeffington, who, as usual, encountered the ill-fortune which seemed to dog his footsteps, for his red Guard's coat was mischievously torn from his shoulders by crazy Lady Caroline Lamb. [9] who hid it and left the discomforted beau in his waistcoat in the centre of the ballroom.
