memory of such readers as might not chance to be intimately
acquainted with the domestic history of the period under consideration,
I have, from the commencement of the work, designated the Duc de Sully
by the title which he ultimately attained, and by which he is
universally known, rather than confuse the mind of my readers by
allusions to M. de Bethune, M. de Rosny, and finally M. de Sully, when
each and all merely signified the same individual; and I feel persuaded
that this arrangement will be generally regarded as a judicious one,
inasmuch as it tends to lessen a difficulty already sufficiently great;
a fact which will be at once apparent on reference to the biographical
table at the head of each volume.

On the other hand I have, contrary to my previous system, but in justice
to myself, carefully, and even perhaps somewhat elaborately, multiplied
the footnotes, in order to give with precision the several authorities
whence I deduced my facts; and I must be excused should this caution
appear uselessly tedious or pedantic to the general reader, as I am
anxious on this occasion to escape the accusation which was once brought
against me when it was equally undeserved, of having "quoted at
secondhand," and even drawn my materials from "historical romances of
the time." It is, of course, easy to make assertions of this nature at
random; but when a writer feels that he or she has conscientiously
performed a duty voluntarily undertaken, it is painful to be misjudged;
especially when, as in the present instance, nearly three years have
been devoted to the work.

For the facsimile letters by which my volumes are enriched I am indebted
to the kindness of M. de la Plane, a member of the Institut Royal de
France, of whose extensive and valuable cabinet of ancient records they
now form a part; and by whom their publication was obligingly
authorized. The authenticity of these letters admits of no doubt, as it
is known that they originally formed a portion of the rich collection of
autographs in the possession of the Marechal de Bassompierre, to whom
they were severally addressed; and that at his death they were
transferred to the library of the Fathers of the Oratory at St. Magloire
in Paris; whence (it is believed at the Revolution) they fell into the
hands of a member of that celebrated society, Le Pere de Mevolhon,
formerly Canon and Vicar-General of the diocese of St. Omer, by whom
they were presented to M. de la Plane.
