Parade on the square.
--At half past 4 o'clock this afternoon, Major Chambliss's (Winder and Jackson Hospitals) battalion will parade on Capitol Square. Included in the battalion is a company of negroes, commanded by Captain Grimes, who will also be present and go through the military evolutions. This is the first company of negro troops which have been raised in Virginia, and was organized about a month ago by Dr. Chambliss from the employees of the hospitals. The men were on the lines during the recent raid.
