The subject of the following “Memoirs,” so far as regards the two points above mentioned, would seem to offer most favourable conditions for the pen of the biographer; nevertheless, the writer confesses that the very facility presented has caused difficulties to spring up in his way. Though utterly a novice in such work, an ardent longing has possessed him to write of one with whom he lived for twenty years on terms of the most intimate friendship, little, if at all, inferior in warmth to consanguineous affection. He has deemed it his duty, after duly weighing the many communications received from his friend in hours of confidential intercourse, and regarding them as illustrative not only of the life of the man himself, but in their wider sense as pertaining to contemporary history, and elucidating the opinions of the great statesmen and other notable individuals with whom the subject of this memoir was in daily intercourse—to show forth his life to the world, calling to aid personal memories of the events recorded, original documents in the writer’s own possession or those he could obtain from others, besides information given orally by friends.
That life, chequered even at the outset by struggle and adventure, devoted to incessant activity, and bound up, as it were, with all the stirring public events of the most active period of our age, being of necessity gathered from documents so voluminous as to constitute a veritable “_embarras de richesses_”—a plethora of material—the mere task of condensation and selection has proved a formidable one; whilst the arrangement of facts following closely on one another has presented at times considerable difficulty.
Other causes have stimulated the biographer in his work, inasmuch as he himself was not unconcerned in some of the more important and exciting events of the life which he records. The struggles of oppressed nationalities, the numerous revolutions and changes of dynasty, the intrigues of politicians throughout Europe, the face of which may be said to have been changed during the middle of this century, the varied events at home, and the vicissitudes of the country which his friend had adopted for his own, and for which he evinced unswerving affection and fidelity, have supplied matter which must be treated at some length in order to depict his life in its true light, and to represent adequately the motive power which prompted his ways and actions.
