The distinction between this history and that of _philology_ or _erudition_ is less apparent but not less indubitable, always, be it well understood, in the sense explained, of a distinction that is not a separation. This warning should be understood in respect of other exclusions that we are about to effect, without our being obliged to repeat it at every step; for the connexion between history and philology is undeniable, not less than that between history and art, or history and practical life. But that does not prevent philology in itself being the collection, the rearrangement, the purification of material, and not history. Owing to this quality it forms a part rather of the history of culture than of that of thought. It would be impossible to disassociate it from the history of libraries, archives, museums, universities, seminaries, _écoles des chartes,_ academical and editorial enterprises, and from other institutions and proceedings of an entirely practical nature. Fueter has therefore been right in excluding from his theme in his recent work on the history of modern historiography[2] "the history of merely philological research and criticism." This has not prevented him from taking store where apposite of the school of Biondo or of that of Maurini, or of the perfecting of the method of seeking for the sources attained by the German school in the nineteenth century. The confusion and lack of development observable in the old and solid work of Wachler[3] is perhaps due to his having failed to make this distinction, to which recourse can also be had with advantage elsewhere. Wachler's work, entitled and conceived as "history of research and of the historical art from the Renaissance of letters in Europe onward," ended by assuming the appearance of a repertory or bibliographical catalogue.
