From our own Correspondent

London, June 23, 1848.

Dear Douglass,ーEurope is no quieter. To begin at home. Mitchell’s conviction, as I before named, has been made the pretext for violent and tumultuous assemblies in many parts both of England and Ireland. They have however, been attended with the most insignificant results, except so far as they have had the effect of strengthening the hands of the executive. At present we are tolerably quiet. The parties of old and young Ireland are attempting to accomplish a fusion. There is, however, no probability of its being long successful. The O’Connells seem to have an intense objection to the physical force doctrines. Hume’s motion for reform was brought on in the House of Commons, on the night of the 20th. A lengthened debate was adjourned until Friday. Lord John, of course, opposed it, but promised moderate reform. The parliament has amply supported the conduct of our government in the late Spanish question; the consequence has been that the Spanish ambassador has left for Madrid; what will be the upshot of this, no one knows. The French appear almost as uneasy under the republic, as beneath their inglorious monarchy. (The rest of our Correspondent’s letter relating to France, is superseded by the more recent intelligence which will be found in another column.ーED.)

In Italy, many military operations have taken place. The Italian army has all along fought gallantly. Charles Albert has displayed personal courage, amounting to rashness. The Austrian army is in full, though slow retreat. Radetjski has behaved with great cruelty to the Venetian towns on his line of march. The lower provinces of the Austrian empire are in terrible confusion. The danger of their entire severance is hereby increasing. The old question of race, never entirely at rest, is being again mooted. A man of considerable intelligence, with whom I was recently conversingーone who, though a Frenchman by birth, has pretty well surmounted his old national prejudices, without acquiring fresh ones, (and to whom the many passages of a long and eventful career, have afforded numberless opportunities of examining the tendencies and aspirations of most nations of Christendom,) stated, that he considered it almost a certainty, that the Czar would not hesitate to take advantage of the decrepitude of Austria, by putting himself at the head of the whole Sclavonic nationsーthe latter, (including Bohemians, Hungarians, Wallachians, Moldavians, and the multitudinous confrerie,) are far more anxious to be altogether quit of the Germans, than to escape monarchical rule. Should this take place, his accession of power will be incalculable. The Germans have lost ground greatly in the Schleswig-Holstein affair. The Danes have the better cause, the better troops, and, best of all, the better feeling. The Swedes have proffered their assistance to their brother Scandinavians; a Russian Grand Duke has been eagerly welcomed at Copenhagen. In Prussia, the king is powerless; the people do almost what they will; and to say the truth, doing as they have recently done, does not do them much credit. The Assembly, profuse in promises, verbose in debate, is, in action, absolutely inert. All this need never have been. The King made a terrible mistake in deferring so long their Constitution.
