Union document.
--The Nashville Patriot, of the 21st, publishes a long memorial written by Mrs. L. Virginia French, and signed by Mrs. Henry Clay, Mrs. Sigourney, Mrs. Terhune, ("Marion Harland,") Mrs. Rosa Vertner Johnson, and other distinguished ladies, which was written to be presented to the Tennessee Convention. It is an appeal for the Union, but as the Convention was not held, it was of course never presented.
