The first, and one of the most painful of these our "modern instances," was very recently related to us by the son of him whose fortunes were changed, and finally his fate sealed, by the unheeded flitting of those few sands of time, and whose family are still sufferers from this apparent trifle. The momentous five minutes to which we allude were a portion of one of the most glorious periods that ever dial or hourglass marked--that in which the Trafalgar victory was won, and Nelson lost. Among the gallant fleet which on that day roused the echoes of the hills of Spain, was a certain cutter commanded by a young lieutenant, who, possessing no naval interest, hoped for advancement only from his own gallantry and good conduct; and little doubt was there that either would prove lacking in his case. Memories of the fair wife and dear babe whose fortunes were, in the expressive language of the East, "bound up in the bundle of his life," awoke every energy of his nature, and gave (for him) a double and inspiring meaning to that celebrated signal, the simple majesty of which still thrills the heart of all who owe homage to the name of our country--"England expects every man to do his duty." When the fight began, our young lieutenant did his duty gallantly; the "angel opportunity" was lacking for any very memorable achievement, but in that scene of unrivaled valor and exertion, the eye of the great commander marked the conduct of the gallant little cutter, and he noticed it to "Hardy." Had he lived, the fortune of the young officer would have been assured; but the life which then "set in bloody glory" bore with it the hopes of many a brave mariner "into the dim oblivion!"
