Lord Mount Charles came to me this morning and consulted me about resigning his seat at the Treasury. He hates it and is perplexed with all that has occurred between the Duke and Lord Anglesey. I advised him to resign, feeling as he does about it. He told me that he verily believed the King would go mad on the Catholic question, his violence was so great about it. He is very angry with him and his father for voting as they do, but they have agreed never to discuss the matter at all, and his mother never talks to the King about it. Whenever he does get on it there is no stopping him. Mount Charles attributes the King's obstinacy to his recollections of his father and the Duke of York and to the influence of the Duke of Cumberland. He says that 'his father would have laid his head on the block rather than yield, and that he is equally ready to lay his head there in the same cause.' He is furious with Lord Anglesey, but he will be very much afraid of him when he sees him. Mount Charles was in the room when Lord Anglesey took leave of the King on going to Ireland, and the King said, 'God bless you, Anglesey! I know you are a true Protestant.' Anglesey answered, 'Sir, I will not be considered either Protestant or Catholic; I go to Ireland determined to act impartially between them and without the least bias either one way or the other.' Lord Anglesey dined with Mount Charles the day before he went. The same morning he had been with the Duke and Peel to receive their last instructions, and he came to dinner in great delight with them, as they had told him they knew he would govern Ireland with justice and impartiality, and they would give him no instructions whatever. He showed me a letter from Mr. Harcourt Lees full of invectives against the Duke and lamentations at the recall, to show how the Protestants regretted him as well as the Catholics.
