_29th._--Professor Dugald Stewart, who has just arrived from Edinburgh, is to go with L. to Paris. Gaeta is taken, and Sr. Sidney has met with some check in the kingdom of Naples.[220] L. had a conversation alone with Mr. F., in which he opened himself freely. He said he wished to retire from office till he got better, and to have Ld. H., whom he had always destined ultimately to succeed him, appointed to fill his place _pro tempore_, adding that he had been thinking of this for some time, but that he had put it off in the hope of being able to sign the peace before he retired. He bid L. ‘open the matter to Ld. Grenville,’ and added that he ‘would talk further on the subject to Ld. Grenville in 8 or 10 days.’ In a conversation which L. had with Ld. Grenville some time ago, during which they talked of Mr. Fox’s situation and of the small prospect of any amendment in his health, Ld. Grenville said, ‘That he hoped his own conduct had been such as to satisfy Mr. Fox’s friends since the period of their being connected together, and if that disastrous calamity should happen, and most disastrous indeed would it be for the country, he trusted, they would have no reason to be dissatisfied with any future arrangements that might take place.’ Sheridan, who dined here to-day, begged to talk to me privately. He said that it was the wish of many of Fox’s friends, whenever the state of his health should make it impossible for him to attend to the duties of his office, that Ld. H. should be appointed his successor; that such an appointment would be regarded by them as a pledge that the Whig Party was still to be kept up, and its principles maintained; that the Prince was very eager to have them carried into effect; that he had spoken to Windham, who seemed to listen with satisfaction. That he, ‘from delicacy, spoke to me instead of to Ld. H., and begged I would communicate the substance of them to him,’ He told me that George Byng and the second-rate sort of politicians were very eager upon the subject. Cline, the surgeon, has seen Mr. Fox, and declares himself ready to perform the operation whenever the physicians shall judge it expedient, as he does not see any reason to think the result more formidable to Mr. F. than to any other person. [Sidenote: A SUCCESSOR TO FOX] Ld. Howick is full of plans for an Administration, in the event of Mr. Fox’s retirement, or worse. He takes for granted that neither the General or Ld. Fitzwilliam would choose to remain in office if F. were away. He would, in that case, make Whitbread Secretary at War, himself S. for the Home Department, Tom Grenville the Admiralty, Tierney the Board of Control, Ld. H., of course, the Foreign Office; and, said I, ‘Pray where do you put Lauderdale, ye first, greatest, and best lord?’
