The London Gazette of last night contains despatches from Admiral

Dundas, dated, "Britannia, off Odessa, April 22,' together with copies of the reply of General Osten-Sacken to the demand for explanations ; of the letter of Captain Loring of the Furious, narrating the entree upon his flag of truce ; of the evidence of John Tate of the barque Princess, in proof of that narrative ; of the summons of the Admirals to surrender the shipping in the port; of the report of Captain Jones, who commanded the attack in the Sampson ; and a list of the killed and wounded. The facts they contain are embodied in the narrative under the head of " Turkey."

Two new points are noticeable in the despatch of Admiral Dundas. He , says, that "in addition to the fortress of Odessa, the Russians were la- bouring day and night in strengthening the moles and erecting formidable sea defences, and had also collected between twenty and thirty thousand men for the protection of this military depot, as well as for the security of vessels seeking shelter under the guns of the place." With respect to the French, he bears this testimony—" It is my pleasing duty to state, that between the two squadrons the greatest cordiality exists, and that the conduct of the French steam-frigates calls for my warmest praise."

Again we have no news of the Baltic fleet beyond this—that intelli- gence brought to the Admiral had caused him to order the fleet to leave Elfsnabben, and sail towards the Gulf of Finland, in order to prevent the junction of the Cronstadt with the Sweaborg squadrons, should such a movement be attempted; and that the French squadron had joined the British fleet.
