_Coleridge's Christabel--The 3rd Part_ (Vol. viii., pp. 11, 12.).--MR. J. S. WARDEN asks if I am correct in stating the 3rd part of _Christabel_ to be the composition of Dr. Maginn. I can but "_give my authority_" in a reference to a sketch of Maginn's life, in a new and well-conducted periodical, _The Irish Quarterly Review_, which, in the number for September, 1852, after giving a most humorous account of a first interview between Blackwood and his wild Irish contributor, who had for more than a year been mystifying the editor by contributions under various signatures, proceeds thus:-- "A few days before the first interview with Blackwood, Maginn had sent in his famous 'Third part of Christabel.' It is only to be found in the Magazine; and as many of our readers must be unacquainted with the poem, we here subjoin it." {112} The poem follows, containing the lines which led to the first inquiry on this subject. It was having read the Memoir in _The Irish Quarterly_ which enabled me so promptly to remember where the lines were to be found; but I had long before heard, and never doubted, that the clever parody was composed by Dr. Maginn. A. B. R. Belmont. _Mitigation of Capital Punishment_ (Vol. viii., p. 42.).--I am sorry MR. GATTY takes the phrase "mythic accompaniments" as an imputation on himself. I did not intend it for one, having no doubt that he repeated the story as he heard it. In it were two statements of the highest decree of improbability. One I showed (Vol. v., p. 434.) to be contrary to penal, the other to forensic practice. One MR. GATTY found to have been only a report, the other to have occurred at a different place and under different circumstances. Had these been stated in the first version, I should not have disputed them. Whittington was thrice Lord Mayor of London--that is history, to which the prophecy of Bow-bells and the exportation of the cat are "mythic accompaniments." A word as to "disclosing only initials." I think you, as a means of authentification, should have the name and address of every correspondent. You have mine, and may give them to any one who pays me the compliment of asking; but I do not seek farther publicity. H. B. C. Oxford. _The Man with the Iron Mask_ (Vol. vii., pp. 234. 344.).--I think that Mr. James, in his _Life and Times of Louis XIV._, has, to say the least, shown strong grounds for doubting the theory which identifies this person with Mathioli; and since then several writers have been inclined to fall back, in the want of any more probable explanation, on the old idea that the captive was a twin brother of Louis. What has become of the letter from M. de St. Mars, said to have been discovered some years ago, confirming this last hypothesis? Has any such letter been published, and, if so, what is the opinion of its genuineness? J. S. WARDEN.
