LATE AND ITPORTANT FROM TEXAS.We have received our regular files of Texas papers from the seat of government to the10ul», and from Galveston to the lilith ult.From tlie Austin C.ty Gazette we extract the ibHowinir :Arrival of Commissioners from Gen. Arista with propositions for an Armistice.—.1.5v the lion. C. Van Ness and Col. W.JG. Cooke, who arrived in town ftom San An-tonio a few days we learn that threeCommissioners or Agents from Gen. Arista to our government had arrived in that place and may be expected here to-day. 11 is generally believed that Gen. Arista proposes a suspension of hostilities, opening a direct trade between Texas and the Mexican provinces,he restraining all marauding parties on his side^jtrodkd Texas will do the same on their side, and a joint and mutual action against the hostile Indians. It is the true policy of this governmentto meet Mexico halfway whenever she does make us an offer of her hand, not only so shou Id shenot forget that, though she may have enacted the partot an unnatural parent, Texas is an offspring of Mexico, many of our citizens are of Mexican birth or Mexican extraction, and look up to that country as their fatherland. Whatever, in our situation, tends to peace, tends also to national happiness and prosperity —whatever leads to a definite or indefinite suspension of threatened hostility, will do much toward the rc-establishment of confidence throughout the whole extent of our western frontier, will encourage em gration, an 1 have a tendency to establish friendly feelings and relations between the inhabitants res .ding east and those residing west of the Rio Grande, and from this will flow, as a natural result, the removal of all those national prejudices which at present unfortunately existbetween the Anglo-American and the Mexican races.
