Sr. Sidney Smith has taken the Isle of Capri, and the French have been worsted in several encounters in Calabria. Hopes are entertained that we shall be able to defend Sicily against the French, with the aid alone of the Sicilians. The Queen and Duke of Calabria, who are surrounded by persons suspected of being secretly in the French interest, are eager for carrying the war into Calabria. Great dissatisfaction at Ld. Yarmouth’s conduct, and another negotiator must go. Ld. Holland not being able to leave his uncle, Lauderdale, as the next best person, is to go. It is a sad mortification, as it has long been the darling hope of uncle and nephew; but it would be impossible to go, as Ld. H., besides being useful, is also one of the greatest comforts to Mr. Fox. Mr. F. so ill that none of the last transactions of the preceding three days have been communicated to him. _27th July._--Mr. Fox stronger, and in better spirits to-day, but there is no material change in his complaint. The news of the Russian Treaty, and the determination of sending Lauderdale to Paris, were communicated to him by Ld. Howick. Upon hearing that L. was to go to Paris, he exclaimed, ‘Why does not Holland go?’ Ld. Howick was perplexed, and stammered by way of excuse the ‘suddenness of the departure’; upon which Fox said, ‘Oh, I understand you!’ and immediately changed the subject. When he saw Ld. Holland about an hour afterwards, he began with saying, ‘So, young one, you won’t go to Paris’; on Ld. Holland’s answering that he preferred staying, as he thought he was a comfort to him, he caught his hand and said, with great emotion, ‘Yes, a comfort indeed,’ and was for several minutes quite overcome and shedding tears. This circumstance is the first event which has given him any apprehension about his own danger. [Sidenote: LORD YARMOUTH’S CONDUCT]
