(4th column, 4th story from bottom) Charles Ingersoll has been arrested for treasonable or discouraging remarks, made at the Democratic meeting in Philadelphia on Saturday last. Mr. Ingersoll, in his speech, denounced President Lincoln and the Government in pretty strong terms, and accused them of disregarding the Constitution, and of being the most corrupt of any in the world. He also stated that our debt was heavier than that of any other nation, and one that had the least prospect of ever being paid.
