In presenting to the Public the fourth and concluding volume of this Correspondence, the Editors desire to acknowledge that they have been much indebted to Mr. Wright, editor of the Parliamentary History of England, &c., for the able assistance which he has afforded them during the progress of this work through the press. The extensive acquaintance with the annals of this country, which that gentleman possesses, added to an indefatigable spirit of research, peculiarly qualify him to furnish the requisite information, to illustrate its political history.
