Of 9 Congressmen, 3 Whigs are chosen, and in 6 districts no choice was effected. Hon. HORACE MANN, the Free Soil candidate, succeeded against both the opposing candidates. To the State Senate 13 Whigs and 27 of the Opposition were chosen; and to the House of Representatives 169 Whigs, 179 Opposition, and in 79 districts there was no choice. The vacancies were to be filled by an election on the 25th of November. A U.S. Senator from this State is also to be chosen, to succeed Hon. R.C. WINTHROP, who was appointed by the Governor to supply the vacancy caused by Mr. WEBSTER's resignation. No more elections for Members of Congress will be held in any of the States (except to fill vacancies) until after March 4th, 1851. The terms of 21 Senators expire on that day--of whom 8 are Whigs, and 13 Democrats. Judging from the State elections already held there will be 6 Whigs and 15 Democrats chosen to fill their places. The U.S. Senate will then stand thus: Holding over 18 Whigs 23 Democrats.

In reference to the contingency of the next presidential election devolving upon the House, for lack of a choice by the people, 9 of the above States would go Democratic, five of them Whig, and one (the State of New York), would have no vote, its delegation being equally divided. The delegations of the same States in the present Congress are as follows, viz., 7 Whig, 7 Democratic, and one (Iowa) equally divided.
