A distinguished man should be as particular about his last words as he is about his last breath. He should write them out on a slip of paper and take the judgment of his friends on them. He should never leave such a thing to the last hour of his life, and trust to an intellectual spurt at the last moment to enable him to say something smart with his latest gasp and launch into eternity with grandeur.
