The chief alteration made in the mode of publication will be perceived at once. Instead of printing the letters of the respective parties in separate volumes, it has now been deemed more judicious to collect them together and arrange them in the precise order of their respective dates, to the end that the references to events or sentiments constantly made on the one side or the other may be more readily gathered and understood. This will show more distinctly the true shape of familiar letters which properly belongs to them. It is not likely that either correspondent, in writing them, ever dreamed that they might ultimately be shown to the world, and perhaps transmitted to the latest posterity. May I be permitted to add an humble opinion that it is this feature in them which constitutes their chief attraction? CHARLES FRANCIS ADAMS. MEMOIR. The memorials of that generation by whose efforts the independence of the United States was achieved are in great abundance. There is hardly an event of importance, from the year 1765 to the date of the definitive treaty of peace with Great Britain, in September, 1783, which has not been recorded, either by the industry of actors upon the scene or by the indefatigable labors of a succeeding class of students. These persons have devoted themselves, with a highly commendable zeal, to the investigation of all particulars, even the most minute, that relate to this interesting period. The individuals called to appear most conspicuously in the Revolution have many of them left voluminous collections of papers, which, as time passes, find their way to the light by publication, and furnish important illustrations of the feelings and motives under which the contest was carried on. The actors are thus made to stand in bold relief before us. We not only see the public record, but the private commentary also; and these, taken in connection with the contemporaneous histories, all of which, however defective in philosophical analysis, are invaluable depositories of facts related by living witnesses, will serve to transmit to posterity the details for a narration in as complete a form as will in all probability ever be attained by the imperfect faculties of man.
