At two o'clock Peel arrived, and upon her informing him that John Russell had resigned, giving him the Minute to read, and requesting him to retake the Government, he immediately and without making any difficulties consented to do so, saying, however, that he would have supported John Russell if he had formed his Government. The Queen wrote to John Russell and told him what had passed, which he announced to us at dinner at Palmerston's. I never saw people so happy, as most, perhaps all of them, are to have got out of their engagement; even Lady Palmerston said she did not wish for the Foreign Office again. It was known yesterday that Howick was the cause of this sudden break-up, and what he had done, and there was a general disposition to blame him severely, but also to blame them for not having let him depart and gone on without him. If they had been really anxious to come in, and if they had had an entire confidence in Peel's intentions, they no doubt would have done so; but the Peers of the party, who were all of them opposed to taking office on Thursday, were still more decidedly against it when they found Howick was to leave them. They had counted upon him as their principal speaker in the House of Lords, and when they found that the whole burthen was to fall on them, and that they were very likely to have Howick against them instead of for them, urging impossible measures, they vehemently pressed John Russell to give it up; and this disinclination on the part of so many members of his Cabinet to face these difficulties determined him to resign. If Peel's engagement to support them had been more definite and positive, they would probably not have cared for Howick's secession; but, already dissatisfied with Peel, they were too happy to take the opportunity which Howick afforded them to draw back altogether. Peel's reserve was really then the cause of the failure, and I have a strong suspicion that he was reserved and abstained from pledging himself because he thought John Russell would very likely not be able to accomplish his task, that in case of failure the Government would fall back into his hands, and that he was resolved all the time to retake it if it was offered to him again. At all events he has shown his prudence, and it is very fortunate for him that he did not pledge himself to any particular course, and that he has kept himself at liberty to do exactly what he pleases. He is not the least pledged either for or against total repeal. The conversation I had with Sidney Herbert some nights ago gave me a suspicion that they were looking forward to the possibility, if not the probability, of their immediate resumption of office. I think, on the whole, Lord John had sufficient reason for giving it up, but that the world--that is, the Whig world--and those who desired his success, who cannot know what was passing in his green-room, will think he ought, after going so far, to have gone on to the end.
