Unofficial mission to Europe.—Uneasy feeling with regard to France.—William Howard Russell’s Diary.

November 6th.–Instead of Mr. Everett and Mr. Johnson, Mr. Thurlow Weed and Bishop Hughes will pay a visit to Europe in the Federal interests. Notwithstanding the adulation of everything French, from the Emperor down to a Zouave’s gaiter, in the New York press there is an uneasy feeling respecting the intentions of France, founded on the notion that the Emperor is not very friendly to the Federalists, and would be little disposed to expose his subjects to privation and suffering from the scarcity of cotton and tobacco if, by intervention, he could avert such misfortunes. The inactivity of McClellan, which is not understood by the people, has created an under-current of unpopularity, to which his enemies are giving every possible strength, and some people are beginning to think the youthful Napoleon is only a Brummagem Bonaparte.
