No work of the kind in the world's literature can for a moment be compared to Pepys's _Diary_; but many circumstances must combine ere the existence of such a book is possible. It is characteristic of Pepys to be at once a very extraordinary and a very ordinary person. In one point of view he is the most perfect representative imaginable of the bourgeois type of humanity, worthy, sensible, indispensable, and at the same time dull, prosaic, and narrow-minded. Yet this solid citizen has a dash of the Gil Blas in him too; and his little rogueries and servilities appear the more amusing by contrast with the really estimable and respectable background of his character. These qualities combined make a perfect hero of autobiography; his ordinary qualities awaken a fellow-feeling for so characteristic a specimen of average humanity, and his deviations from the straight path communicate the piquancy of comedy, sometimes the exuberance of farce. Extraordinary he is too, for assuredly no one ever recorded his thoughts and actions with such absolute sincerity; or if anyone ever did, his thoughts and actions were not worthy of record. Those of Pepys, somehow, always seem worthy of being perpetuated. However trivial they may sometimes be, they are saved by the writer's admirable manner, and the contagious earnestness of his conviction that they are in truth of deep concern. The reader, moreover, is continually exercised by the problem whether his author is really aware of the display he is making of himself. If he is, he is a miracle of courage; if not, his obtuseness is equally extraordinary. The _Diary_, besides, is no less admirable as a delineation of the macrocosm than of the microcosm. It paints the official and private circles in which the author moved, the course of public affairs, the humours of social life, with no less truth and frankness than it reveals the author himself. It is by far the most valuable document extant for the understanding of the times; better than all the histories and all the comedies. It seems an unequalled piece of irony that the supreme piece of workmanship in its way and the most lucid mirror of its age should be the performance of an ordinary citizen who had not the least idea that he was doing anything remarkable; who expected celebrity, if he expected it at all, from his official tasks and scientific recreations; who shrouded his work in shorthand lest the world should profit by it; and who would have been dismayed beyond measure if he had foreseen that it would be published after his death. Many chances have conspired for its preservation; it is wonderful that the writer should not have destroyed it; beyond expectation that he should have bequeathed it to Magdalen College; fortunate, to say the least, that it should have been so well preserved there, and have attracted attention at last. We shall never be able to determine whether we have more reason to be thankful that it was
