The wreck of the ship Reliance, stranded last fall at Matane, has been floated off and arrived here yesterday. We have not heard of any of the other wrecks below having been floated with the present spring-tides. The steamer North America left for Montreal on Sunday with Mr Lee's new ship Jemima in tow, where she is to load.

The Alliance will also leave for Montreal this afternoon, with Mr. Jeffery's new ship Euthorpe.

The bark Countess of Durham, Tuzo, arrived here on Sunday afternoon from Jeremy Island, where she wintered, having put in there last fall from stress of weather, on her way to Glasgow with a cargo of flour, wheat, &c.

The Steamship St. George, which left here on the 9^th instant, for the Traverse, to lay down the buoys, only returned yesterday morning. She was detained two or three days waiting for the ice to move out of the Saguenay before laying down the buoys: but it was still fast when she left that place on Sunday morning.

The St. George only saw one vessel bound up, below Green Island.

The bark Syria, Cox, from Liverpool for Montreal, with a general cargo, and about 299 passengers is detained at the Quarantine. Capt. Cox and one of his passengers arrived her on Saturday.

By this Morning's Mail.
The Albany Argus of the 11^th contains later news from Mexico. Jalapa & Perote have been occupied. Santa Anna was at Orizaba, a little mountain of that name, with about 1000 troops. Arrangements are in the course of completion for a naval expedition to the Southward, and a start will be made after the ports along the Southern coast have been secured. General Scott is said to have despatched a messenger to Mexico or to the point occupied by the Legislative junta.

General Worth continued to advance upon the capital.

A hurricane recently passed over Madison, Indiana, which prostrated several buildings, killed one man, and injured several others.

Some fifteen or sixteen houses were burned in Nashville, Tenn, on the 5^th inst.

Captain Doubleday, of the Mary, arrived this morning, spoke, on the 10^th instant, the brig Findon, of Poole, bound to Quebec, in long. 59, fast in the ice, with bow stove in and other damage. The Captain wanted no assistance, intending to put into the first port.

Launches.-Three more splendid new vessels were launched at St. Roch's yesterday morning; one by Messrs. G.H. Parke & Co., called the Riverdale; one by Mr. T.C. Lee, of 816 tons, called the Conrad, and the other by Mr. Thomas Oliver, called the Emperor.

Several packets arrived to-day: The Quebec, London, Iowa, Havre, Garrick, Montezuma and Liverpool.

The Atlas mentions the probable loss of the Boston packet ship Anglo-Saxon, Capt. Gordon, which left that port for Liverpool, on the 5^th instant, with about 90 passengers and a valuable cargo. The intelligence was brought to Boston by the British schr. Hope, Capt. Jaques, from Yarmouth, Nova Scotia, who reports a vessel answering exactly in description to the Anglo-Saxon, as being on shore at Duck Island, near Sable Harbour. The crew and passengers, a list of who is given, were all saved; but it was not known whether they had saved their personal property. In looking over the names, we find they are all natives of the United States, except one, a Mrs. Ellen McHugh of England.

The Ship Delia, Adey, arrived yesterday afternoon, brought up Captain Crosby and seven of the crew of the brig Hellespont, of Providence, from New York, bound to Cork, laden with grain, having been abandoned in a leaky state, in lat. 46, 21, long, 36, 37.

North Polar Expedition.-The plan of an overland expedition to the north pole, under the direction of Dr. Sir John Richardson, of Haslar Hospital, has been submitted by him to the Government, and approved of; and directions have been issued to commence providing the necessary supplies of stores and provisions for the party who are to form the members. Dr. Richardson accompanied Sir J. Franklin in his expedition to the north pole in 1819. The officers of Clarence-yard, Portsmouth, have been directed to furnish 300 rounds of beef, and 5000 lbs of lard, which will be made into pemmican cakes, as part of the provisions to be taken out. It is to be made under the immediate superintendence of Sir John Richardson.

Italy.-A most diabolical plot to murder the Pope has been discovered. It was first found out by the French ambassador, and he revealed the names of the conspirators to the Pope. Their intention was to assassinate him whilst giving audience to one of them who was, by lot, to be appointed to kill him. A Capuchin presented himself for an audience of the Pope. His Holiness requested his name; this he gave boldly, but before being admitted the Pope looked over the list of the conspirators and found the name of the Capuchin there. He immediately called for and concealed six carbineers, who, on the Capuchin's entrance seized him, and on searching him found he had a brace of loaded pistols and a poisoned dagger about his person. The Capuchin was conveyed to prison. Many arrests have taken place. This plot is no doubt a concoction.

Also-Tom Bowline, Indus, Richibueto, Countess of Mulgrave, Harvey, Camden, Asia, John Kerr, Chapmans, Symmety, Aberdeen, Feronia, Ajax, brig Mersey, and Britannia.

The U.S. sloop of war Jamestown, Capt. R.B. Forbes, loaned by the U.S. Government to the committee for the relief of the starving poor of Ireland and Scotland, and which sailed from Boston, March 28, returned on the 16^th instant.

The loss of the Boston packet ship Anglo Saxon is confirmed. When the passengers left the wreck they were unable to take anything with them but what they had on; and on returning to the wreck to get their baggage, they found nearly all completely saturated with sea water. The people in the vicinity had been on board, had broken open many of the trunks, valises, &c., and robbed them of their most valuable contents. The cargo, it is presumed, will be very badly damaged, and although a considerable part will be saved, probably not much will be realised from it.

The Hon. Mr. Baillie had arrived at St. John's N.B., and immediately proceeded to Halifax, N.S. As Capt. Robinson (Capt. Pipon's successor) of the Railroad and Boundary survey, was expected to arrive in the Steamer Caledonia, it is said that Mr. Baillie's mission is connected with the Boundary question, and there is reason to believe that the views of the Imperial Government upon that subject will soon be made known.

Sealers Arrived.-Total arrivals at St. John's N.F. 61 vessels, 219,950 seals. The Cumberland, Smart, belonging to Messrs. ? Tobin & Co. with 500 seals on board, got jammed in the ice in a gale of wind on the 10^th; finding that she leaked badly, Captain Smart bore away for a harbour, but the water gained on the crew so that she filled before reaching lad, and sank about 6 miles off Cape Bonavista-crew saved.--

Her Majesty's steamer Vesuvius, from Halifax, with specie for the Commissariat, has just come into port.

We understand that the English mail arrived Thursday, has brought instructions to the Collector at this Port, permitting, under certain regulations, Foreign vessels to go in Ballast to Montreal for the purpose of bringing down Corn, Maize, Grain, Flour, Meal, Rice, or Potatoes, consigned to any Port in the United Kingdom, there to be imported under the act 10 Victoria, Cap. 2, allowing until 1^st September, 1847, the importation of Corn, &c., into the United Kingdom from any country in foreign ships.

The new steamer John Munn, built last fall at the ship-yard of John Munn, Esq., for the "People's Line," leaves this port tonight on her first trip to Montreal. She is upwards of 30 feet longer than the Quebec, and is in every respect, both as regards model and internal arrangements, one of the finest boats that have yet appeared on our waters. (Note: an ad in the same paper lists the fare as 15s for Cabin and 5s for steerage.)

The weather is very cool here for the season: this morning at 7 o'clock the Thermometer did not range over 53. We have had no rain for upwards of a month: the country is already beginning to feel its want.

Loss of a Steamer.--Escape of Eighty Human Beings.--The General Steam Navigation Company's steam-ship Clarence arrived at the company's wharf, Poplar, yesterday afternoon, from Edinburgh. Commander Laker reports that about one o'clock on Friday morning, off Aldborough, he saw the screw steamer Experiment on fire.
