Saw Madame de Lieven yesterday, who told me the story of the late business at St. Petersburg. The Sultan after the battle of Koniah applied to the Emperor of Russia for succour, who ordered twelve sail of the line and 30,000 men to go to the protection of Constantinople. At the same time General Mouravieff was sent to Constantinople, with orders to proceed to Alexandria and inform the Pacha that the Emperor could only look upon him as a rebel, that he would not suffer the Ottoman Empire to be overturned, and that if Ibrahim advanced 'il aurait affaire a l'Empereur de Russie.' Orders were accordingly sent to Ibrahim to suspend his operations, and Mouravieff returned to Constantinople. Upon the demand for succour by the Sultan, and the Emperor's compliance with it, notification was made to all the Courts, and instructions were given to the Russian commanders to retire as soon as the Sultan should have no further occasion for their aid. So satisfactory was this that Lord Grey expressed the greatest anxiety that the Russian armament should arrive in time to arrest the progress of the Egyptians. They did arrive--at least the fleet did--and dropped anchor under the Seraglio. At this juncture arrived Admiral Roussin in a ship of war, and as Ambassador of France. He immediately informed the Sultan that the interposition of Russia was superfluous, that he would undertake to conclude a treaty, and to answer for the acquiescence of the Pacha, and he sent a project one article of which was that the Russian fleet should instantly withdraw. To this proposition the Sultan acceded, and without waiting for the Pacha's confirmation he notified to the Russian Ambassador that he had no longer any wish for the presence of the Russian fleet, and they accordingly weighed anchor and sailed away. This is all that is known of the transaction, but Madame de Lieven was loud and vehement about the insolence of Roussin; she said the Emperor would demand 'une satisfaction eclatante'--'le rappel et le desaveu de l'amiral Roussin,' and that if this should be refused the Russian Ambassador would be ordered to quit Paris. She waits with great anxiety to see the end of the business, for on it appears to depend the question of peace or war with France. She said that the day before Namik went away intelligence of this event arrived, which Palmerston communicated to him. The Turk heard it very quietly, and then only said, 'Et ou etait l'Angleterre dans tout ceci?' [Page Head: PRECARIOUS STATE OF THE GOVERNMENT.]
