The mail-steamer Britannia, which left Boston on the let instant,

arrived at Liverpool yesterday. The most important political news from the United States, is the report that either Mr. Mason of Virginia, or Mr. Charles Ingersoll of Phila- delphia, would be sent on the mission to this country. Some alarm had been excited by the recent movements of the Mormons; who' were constantly collecting arms and other munitions of war from all parts of the country where they have settlements, and depositing them in their "holy city" of Nanvoo; to which notable metropolis the disciples themselves were gathering as fast as they could. The Repeaters of Norfolk, in Virginia, had followed the example of their fellows at Baltimore, and dissolved their associations.

Pittsburgh had. again been the scene of a disastrous fire; which destroyed up- wards of 50 dwellings. The entire loss is estimated at 30,000 dollars, and BOUM 600 labourers were rendered houseless.

Intelligence that Texas had sought to obtain from Mexico an acknowledg- ment of her independence, through the medium of Mr. Elliot, who had gone to the Spanish American capital, and the publication of Senor Cuevas's address to the Mexican Congress upon the subject, had excited much surprise. The semi-offi- cial Union, of Washington, says that that movement to defeat annexation is too late.

The last accounts from California state that that country has declared its inde- pendence of the Mexican Government, and organized itself into a republic. We un- derstand that advices have also been received by the Government at Washington, confirming in every particular this interesting intelligence.—New York Heraftl
