All that is known of his embassy to Russia is, that he was completely bit by the Emperor Nicholas, and gave up the question of the 'Vixen;' still, by dint of being perpetually cried up by a particular party, and by doing well the little he has occasionally done in public, he has succeeded in making himself pass for a man of high pretensions and uncommon endowments, and in the present state of parties his arrival may be productive of important effects. [Page Head: IRRITATION OF THE RADICALS.] The Radicals, that is, the English ones, are extremely exasperated against the Government, and many of them are anxious to terminate the Whig reign, from which they think it vain to expect anything after John Russell's declaration, and to try their chance with the Tories: not that they expect to find the Tories squeezable, but they fancy that a Tory Government will fail, and, after its failure, that recourse must be had to them. The wiser heads of the party know that these notions are quite chimerical, and are for trusting to the chapter of accidents and letting the present Cabinet remain in. The consequence is, that there is great dissension and vast difference of opinion among them; they have no leader, and there is no individual who influences the determinations of the whole body. On the other side of the water, O'Connell has likewise threatened to insist upon ballot as the condition of his support to Government; but nobody pays any attention to his harangues or the menaces they contain, and his support may be pretty well depended on. But it would not be enough for Government that the English Radicals should abstain from going against them in a body, because so slender is the majority on which they can count, that if any considerable number were to oppose Government on some vital question, it would be sufficient to overthrow them. Of this they are aware, as well as of the probability of such defection, and the consequent precariousness of their situation, and many among them are beginning to be very tired and disgusted with such a tenure of office. It is difficult to believe that Melbourne would not be more so than anybody, if it were not that he is bound by every sentiment of duty, gratitude, and attachment to the Queen to retain the Government as long as he can with honour and safety, and to stretch a point even, to spare her the pain and mortification of changes that would be so painful to her. The Tories, who see the accumulating difficulties of the Government, and who are aware of the immense importance of letting it dissolve of itself, or be broken up by the defection and opposition of its own supporters, are disposed to be patient and moderate; that is, the more sagacious of them are; but they are always in danger of being prematurely urged on by the violence and impetuosity of their tail. Such is the state of parties at the present moment, and it would puzzle the most sagacious observer and most experienced actor in political life to predict
