“ In personal appearance Halleck was rather below the medium height and well built: in walking he had a rather slow and shuffling gait, as if something afflicted his feet; a florid, bland and pleasant countenance; a bright gray eye; was remarkably pleasant and courteous in conversation, and, as a natural consequence, much beloved by all who had the pleasure of his acquaintance. But to that brilliancy in conversation which some of his admirers have been pleased to attribute to him in my opinion he could lay no claim. His library was sold at auction in New York on the evening of October 12, 1868. ”
