“These volumes are the most popular of the series of Buckingham papers, not only from the nature of the matter, but from the closeness of the period to our own times.”--_Spectator._
“There is much in these volumes which deserves the perusal of all who desire an intimate acquaintance with the history of the period. The comments of well-informed men, like Lord Grenville, and Mr. T. Grenville, disclosing as they do the motives of individuals, the secret movements of parties, and the causes of public events, are of high value to the student, and exceedingly interesting to the general reader.”--_Daily News._
“These volumes are of great intrinsic and historical value. They give us a definite acquaintance with the actions, a valuable insight into the characters, of a succession of illustrious statesmen.”--_Critic._
“The original documents published in these volumes--penned by public men, who were themselves active participators in the events and scenes described--throw a great deal of very curious and very valuable light upon this period of our history. The private letters of such men as Lord Grenville, Mr. T. Grenville, Mr. Charles Wynn, Mr. Freemantle, Dr. Phillimore, and Mr. Plumer Ward, written in the absence of all restraint, necessarily possess a high interest even for the lightest and most careless reader; whilst, in an historical sense, as an authentic source from which future historians will be enabled to form their estimate of the characters of the leading men who flourished in the reign of the last George, they must be regarded as possessing an almost inestimable value. The more reserved communications, too, of such men as Lord Liverpool, the Duke of Wellington, the Marquis of Wellesley, Sir Henry Parnell, &c., will be received with great interest and thankfulness by every historiographer, whilst the lighter _billets_ of Sir Walter Scott and Mr. Henry Wynn will be welcome to every body. Taking this publication altogether, we must give the Duke of Buckingham great credit for the manner in which he has prepared and executed it, and at the same time return him our hearty thanks for the interesting and valuable information which he has unfolded to us from his family archives.”--_Observer._
