We thank our correspondent C. W. L. for pointing out the resemblance between the little epigram entitled "_The Mistake Corrected_," in our last, and the "_Surprise_," in Little's poems, which he quotes. The resemblance is certainly strong, and it is quite probable that the former if not borrowed was at least suggested by the latter. We cannot agree however, that it is a "plagiarism," in the proper sense of that term; for we know too well the personal and literary character of the gentleman who presented us with the trifle referred to, to suspect him for a moment of so paltry a proceeding. We rather conclude therefore, that its resemblance to Moore's bagatelle, is either the result of casual coincidence,--or more probably, perhaps, of an accidental mistake of the product of memory for that of fancy; a kind of mistake which those who have read much are very liable to make. We assure our correspondent B. R. B. that we have carefully compared the lines published in our last with his manuscript, and find them to correspond _verbatim_. He wrongs us much if he thinks we would do him wilful injustice; and if one word has been substituted for another in the lines referred to, so as to change their sense, he must ascribe it to himself. We hope with this explanation he will excuse us from inserting his letter at full length. There is a great deal of feeling in many of the communications sent to the publisher by T. H. C., M.D.; but to our poor taste, there is not much _poetry_. We question whether the Doctor will not find the lancet and pill box of more profit in that warm region to which he has emigrated, than the offerings of his prolific muse. The poetical manufacture depends more upon the _quality_ than the _quantity_ of its fabrics, for success.
