Everything is getting on very quietly in the House of Commons, and the Opposition are beginning to squabble among themselves, some wishing to create delay, and others not choosing to join in these tricks, when they know it is useless. The Duke came here the night before last, but I was not at home. He talked over the whole matter with his usual simplicity. The King, it seems, was highly pleased with the Winchelsea affair, and he said, 'I did not see the letter (which is probably a lie); if I had, I certainly should have thought it my duty to call your attention to it.' Somebody added that 'he would be wanting to fight a duel himself.' Sefton said, 'he will be sure to think he has fought one.' Hume gave the two Lords a lecture on the ground after the duel, and said he did not think there was a man in England who would have lifted his hand against the Duke. Very uncalled for, but the Duke's friends have less humility than he has, for Lord Winchelsea did not lift his hand against him. It is curious that the man who threw the bottle at Lord Wellesley in Dublin (and who is a Protestant fanatic) has been lurking constantly about the House of Lords, so much so that it was thought right to apprise Peel of it, and the police have been desired in consequence to keep a strict watch over him, and to take care that he does no mischief. The Duke after the duel sent Lord Melville to the Duke of Montrose with a message that his son-in-law had behaved very much like a gentleman. The women, particularly of course Lady Jersey, have been very ridiculous, affecting nervousness and fine feeling, though they never heard of the business till some hours after it was over. Mrs. Arbuthnot was not so foolish but made very light of it all, which was in better sense and better taste. M---- told me two days ago that, although he is more quiet, the King is not at all reconciled to the Catholic question. His Majesty was very much annoyed at his speech the other day, having always hoped that he was at heart too indifferent about it to take a decided line or express publicly a strong opinion. It is supposed that either Sugden or Alderson will be Solicitor-General. O'Connell has done himself great credit by his moderation in the Committee. Grattan wanted to move an amendment omitting the words by which O'Connell is excluded from taking his seat for Clare, when Rice and Duncannon begged him to withdraw it, and said they were charged with the expression of O'Connell's wish that his individual case should not be thought of, as he would not have it be any impediment to the success of the measure. This, of course, greatly annoys those who have inveighed against him, and who have always contended that he only wished for confusion, and would be very sorry to see the question settled.
