PORTER, DARBY, and MILLER, are known to be Whigs. In the other two districts the result has not been ascertained. The change which this result indicates, is attributed to the course taken by Senator BENTON, in refusing to obey the instructions of the state legislature, and in denouncing them as connected with the scheme of disunion, which he charged upon certain southern politicians. This led to a division in his own party, which enabled the Whigs to elect a part, at least, of the Congressional delegation.--In North Carolina an election for governor, has resulted in the choice of Col. REID, Democrat, by 3000 majority. In the state senate the Democrats have four, and in the house they have 10 majority. This enables them to choose a democratic U.S. Senator in place of Mr. MANGUM, the present Whig incumbent.--In Indiana the election has given the Democrats control of the legislature and of the state convention for the revision of the constitution.--The authorities of Buffalo some weeks since, hearing that Lord Elgin, Governor of Canada, was about to visit their city, prepared for him a public reception. Circumstances prevented the fulfillment of the purpose, but the courtesy of the people of Buffalo was communicated by Lord Elgin to his government at home, and acknowledged by Earl Grey in a letter to our Department of State.

This interchange of courtesies is peculiarly creditable to both parties, and highly gratifying to both countries.--The Legislature of Wisconsin has enacted a law making it a penal offence for any owner or lessee of land to allow the Canada thistle to go to seed upon it.--The Board of Visitors appointed by the Government to attend the annual examination at West Point, have made their report, giving a detailed account of their observations, and concluding by expressing the opinion, that the Military Academy is one of the most useful and highly creditable in our country; that it has been mainly instrumental in forming the high character which our army now sustains before the civilized world, and that it is entitled to the confidence and fostering care of the Government.--Hon. HENRY CLAY has been spending the August weeks at Newport, R.I. He has received essential benefit from the sea-bathing and the relief from public care which his temporary residence there affords.--Commodore JACOB JONES, of the United States Navy, died at his residence in Philadelphia, on the 3d ult. He was in the 83d year of his age, and stood nearly at the head of the list of post captains, Commodores BARRON and STEWART only preceding him.
