FOOTNOTES:

[1] Manuscripts of the whole work have, however, been procured, and are now being published on the Continent, but not in time to be available for this work. They will serve hereafter to correct, perhaps, some of the doubtful points of the history on which, from the scantiness of the material, I may have gone astray.
