Paper Office and the MS. department of the British Museum. Although both
these great national depositories are in admirable order, it is to be
regretted that they are not all embraced in one collection, as much
trouble might then be spared to the historical student, who is now
obliged to pass frequently from the one place to the other, in order to,
find different portions of the same correspondence.

From the royal archives of Holland I have obtained many most important,
entirely unpublished documents, by the aid of which I have endeavoured to
verify, to illustrate, or sometimes to correct, the recitals of the elder
national chroniclers; and I have derived the greatest profit from the
invaluable series of Archives and Correspondence of the Orange-Nassau
Family, given to the world by M. Groen van Prinsterer. I desire to renew
to that distinguished gentleman, and to that eminent scholar M. Bakhuyzen
van den Brink, the expression of my gratitude for their constant kindness
and advice during my residence at the Hague. Nothing can exceed the
courtesy which has been extended to me in Holland, and I am deeply
grateful for the indulgence with which my efforts to illustrate the
history of the country have been received where that history is best
known.

I have also been much aided by the study of a portion of the Archives of
Simancas, the originals of which are in the Archives de l'Empire in
Paris, and which were most liberally laid before me through the kindness
of M. le Comte de La Borde.

I have, further; enjoyed an inestimable advantage in the perusal of the
whole correspondence between Philip II., his ministers, and governors,
relating to the affairs of the Netherlands, from the epoch at which this
work commences down to that monarch's death. Copies of this
correspondence have been carefully made from the originals at Simancas by
order of the Belgian Government, under the superintendence of the eminent
archivist M. Gachard, who has already published a synopsis or abridgment
of a portion of it in a French translation. The translation and
abridgment of so large a mass of papers, however, must necessarily occupy
many years, and it may be long, therefore, before the whole of the
correspondence--and particularly that portion of it relating to the epoch
occupied by these volumes sees the light. It was, therefore, of the
greatest importance for me to see the documents themselves unabridged
