[THE reader is to understand this present paper, in its two sections of _The Vision_, &c., and _The Dream-Fugue_, as connected with a previous paper on _The English Mail-Coach_. The ultimate object was the Dream-Fugue, as an attempt to wrestle with the utmost efforts of music in dealing with a colossal form of impassioned horror. The Vision of Sudden Death contains the mail-coach incident, which did really occur, and did really suggest the variations of the Dream, here taken up by the Fugue, as well as other variations not now recorded. Confluent with these impressions, from the terrific experience on the Manchester and Glasgow mail, were other and more general impressions, derived from long familiarity with the English mail, as developed in the former paper; impressions, for instance, of animal beauty and power, of rapid motion, at that time unprecedented, of connection with the government and public business of a great nation, but, above all, of connection with the national victories at an unexampled crisis,--the mail being the privileged organ for publishing and dispersing all news of that kind. From this function of the mail, arises naturally the introduction of Waterloo into the fourth variation of the Fogue; for the mail itself having been carried into the dreams by the incident in the Vision, naturally all the accessory circumstances of pomp and grandeur investing this national carriage followed in the train of the principal image.] What is to be thought of sudden death? It is remarkable that, in different conditions of society it has been variously regarded as the consummation of an earthly career most fervently to be desired, and, on the other hand, as that consummation which is most of all to be deprecated. Cæsar the Dictator, at his last dinner party, (_coena_,) and the very evening before his assassination, being questioned as to the mode of death which, in _his_ opinion, might seem the most eligible, replied--"That which should be most sudden." On the other hand, the divine Litany of our English Church, when breathing forth supplications, as if in some representative character for the whole human race prostrate before God, places such a death in the very van of horrors. "From lightning and tempest; from plague, pestilence, and famine; from battle and murder, and from sudden death,--_Good Lord, deliver us_." Sudden death is here made to crown the climax in a grand ascent of calamities; it is the last of curses; and yet, by the noblest of Romans, it was treated as the first of blessings. In that difference, most readers will see little more than the difference between Christianity and Paganism. But there I hesitate. The Christian church may be right in its estimate of sudden death; and it is a natural feeling, though after all it may also be an infirm one, to wish for a quiet dismissal from life--as that which _seems_ most reconcilable with meditation, with penitential retrospects, and with the humilities of farewell prayer.
