REUNION - Frederick Douglass, in a letter to the "American Baptist," announces the arrival at Rochester of his lost brother, Perry and family. The letter concludes as follows: "The meeting with my brother, after nearly forty years' separation, in an event altogether too affecting for words to describe. How unutterable accursed is slavery, and how unspeakably joyful are the results of its overthrow! The search now being made and the happy reunions now taking place all over the South, after years of separation and sorrow, furnish a subject of the deepest paths."
