_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?
