have endeavored to present him with such an account of the state of
affairs, both before the accession, and at the demise of the Catholic
sovereigns, as might afford him the best points of view for surveying the
entire results of their reign.

How far I have succeeded in the execution of this plan, must be left to
the reader's candid judgment. Many errors he may be able to detect. Sure I
am, there can be no one more sensible of my deficiencies than myself;
although it was not till after practical experience, that I could fully
estimate the difficulty of obtaining anything like a faithful portraiture
of a distant age, amidst the shifting hues and perplexing cross lights of
historic testimony. From one class of errors my subject necessarily
exempts me; those founded on national or party feeling. I may have been
more open to another fault; that of too strong a bias in favor of my
principal actors; for characters, noble and interesting in themselves,
naturally beget a sort of partiality akin to friendship, in the
historian's mind, accustomed to the daily contemplation of them. Whatever
defects may be charged on the work, I can at least assure myself, that it
is an honest record of a reign important in itself, new to the reader in
an English dress, and resting on a solid basis of authentic materials,
such as probably could not be met with out of Spain, nor in it without
much difficulty.

I hope I shall be acquitted of egotism, although I add a few words
respecting the peculiar embarrassments I have encountered, in composing
these volumes. Soon after my arrangements were made, early in 1826, for
obtaining the necessary materials from Madrid, I was deprived of the use
of my eyes for all purposes of reading and writing, and had no prospect of
again recovering it. This was a serious obstacle to the prosecution of a
work requiring the perusal of a large mass of authorities, in various
