It is not, however, necessary to give a detailed list of authorities, which would be little more than a catalogue of the lives, letters, and memoirs of most of the important men of the time. Of these the number is constantly being augmented, and it is from them and the contemporary tracts, monographs, pamphlets, and fugitive writings that the details of the History must be drawn.
