Mr. FRITH is, first and foremost, a humorist, and, in his humour, so like THACKERAY, and so unlike DICKENS, that it is no wonder, considering the consistent inconsistency of human nature, he should have loved the latter, and disliked the former. Yet, with all his aversion to THACKERAY, personally--and "all his works" too, apparently, as he hardly mentions them--he records something very remarkable about the Satirist of the Snobs which could not be guessed at from THACKERAY'S own letters, nor from the anecdotes told about him. And it is this; that THACKERAY could make, and on occasion did make an excellent after-dinner speech. At the Macready banquet with BULWER LYTTON and DICKENS present, Mr. FRITH tells us, "THACKERAY also spoke well and very humorously." And there are three other instances; so that THACKERAY, who has recounted his own failure at the Literary Fund dinner, and whose utter collapse at the Cornhill Magazine dinner is a matter of Literary history, was not always a mistake as an after-dinner speaker. The modesty exhibited by Mr. FRITH in this autobiography is an exhibition as novel and attractive as was FRITH'S other exhibition in Bond Street,--because few autobiographers possess so keen a sense of humour as to be able to laugh at themselves, and to be candid about their own foibles and follies. Indeed some persons may think, and indeed he inclines to this opinion himself, that he goes too far in his frankness when narrating the practical jokes of that unscrupulous and cruel _farçeur_ SOTHERN the actor, in some of which the autobiographer appears to have played a small, but not altogether unimportant part. In his way Mr. FRITH is as frank and open in his revelations as to his past career, as was Cardinal NEWMAN in his straightforward _Apologia pro suâ vitâ_. In fact in these SOTHERN latitudes--there was a great deal of latitude in that quarter--Mr. FRITH'S work is suggestive less of an autobiography than of a naughty-biography. He owns that he feels "humiliated and pained" at recounting THACKERAY'S rude jocularity towards himself, and from the apologetic tone with which he introduces some of SOTHERN'S caddish practical jokes, in which Mr. FRITH had no share, and of which he was not the victim, it may be inferred that he had already begun to feel "humiliated and pained" at having given so much space to such stories. How glad he must now be that he kept a "dear Diary," which has been an invaluable aid to his memory.
