et Correspondence” of the Orange Nassau family, edited by the learned and distinguished Groen van Prinsterer, have been my constant guides through the tortuous labyrinth of Spanish and Netherland politics.  The large and most interesting series of pamphlets known as “The Duncan Collection,” in the Royal Library at the Hague, has also afforded a great variety of details by which I have endeavoured to give color and interest to the narrative.  Besides these, and many other printed works, I have also had the advantage of perusing many manuscript histories, among which may be particularly mentioned the works of Pontua Payen, of Renom de France, and of Pasquier de la Barre; while the vast collection of unpublished documents in the Royal Archives of the Hague, of Brussels, and of Dresden, has furnished me with much new matter of great importance.  I venture to hope that many years of labour, a portion of them in the archives of those countries whose history forms the object of my study, will not have been entirely in vain; and that the lovers of human progress, the believers in the capacity of nations for self-government and self-improvement, and the admirers of disinterested human genius and virtue, may find encouragement for their views in the detailed history of an heroic people in its most eventful period, and in the life and death of the great man whose name and fame are identical with those of his country.

No apology is offered for this somewhat personal statement.  When an unknown writer asks the attention of the public upon an important theme, he is not only authorized, but required, to show, that by industry and earnestness he has entitled himself to a hearing.  The author too keenly feels that he has no further claims than these, and he therefore most diffidently asks for his work the indulgence of his readers.

I would take this opportunity of expressing my gratitude to Dr. Klemm, Hofrath and Chief Librarian at Dresden, and to Mr. Von Weber, Ministerial-rath and Head of the Royal Archives of Saxony, for the courtesy and kindness extended to me so uniformly during the course of my researches in that city.  I would also speak a word of sincere thanks to Mr. Campbell, Assistant Librarian at the Hague, for his numerous acts of friendship during the absence of, his chief, M. Holtrop.  To that most distinguished critic and historian, M. Bakhuyzen van den Brinck, Chief Archivist of the Netherlands, I am under deep obligations for advice, instruction, and constant kindness, during my residence at the Hague; and I would also signify my sense of the courtesy of Mr. Charter-Master de Schwane, and of the accuracy with which copies of MSS. in the archives were prepared for me by his care.  Finally, I would allude in the strongest language of gratitude and respect to M. Gachard, Archivist-General of Belgium, for his unwearied courtesy and manifold acts of kindness to me during my studies in the Royal Archives of Brussels.
