is "Further Notes"[14] on that
subject, the same idea is prominent. All of these writers, with the
exception of Sir Thomas Browne (and excluding Dr. Tylor in so far as
regards some of his deductions), refer practically, though in varying
degrees, to the question discussed by Tyson; and in this respect I must
also cite my recent work on "The Ainos" (pp. 51-66). Of other writers
who have not probed quite so deeply, and who possibly may not recognise
the necessity for so doing, but who are realists nevertheless, the
following may be mentioned: M. Paul Monceaux, who, in the _Revue
Historique_ of October 1891, deals with the African dwarfs of ancient
and modern writers;[15] Professor Henri van Elven, the main theme of
whose forthcoming work, _Les Nains prehistoriques de l'Europe
Occidentale_, formed the subject of a paper recently read by him before
the _Societe d'Archeologie de Bruxelles;_ and MM. Grandgagnage and De
Reul, cited by Mr. C. Carter Blake, F.G.S., in connection with the
_Nutons_ of the Belgian bone-caves;[16] as also another writer of the
Low Countries, Van den Bergh ("xxx. and 313"), whom Mr. J. Dirks quotes
at p. 15 of his _Heidens of Egyptiers_, Utrecht, 1850. In Mr. W.G.
Black's charming book on Heligoland,[17] one passage (p. 72) recognises
that a certain Sylt tradition "is evidently one of those valuable
legends which illuminate dark pages of history. It clearly bears
testimony to the same small race having inhabited Friesland in times
which we trace in the caves of the Neolithic age, and of which the
Esquimaux are the only survivors." For many of the kindred traditions in
that locality, one cannot do better than refer to Mr. Christian Jensen's
_Zwergsagen aus Nordfriesland_, contributed to the _Zeitschrift des
Vereins fuer Volkskunde_ (Berlin, Heft 4, 1892).

[The foregoing pages were all in type before the appearance of Vol.
VIII. of the _Bibliotheque de Carabas_, which contains several
criticisms by Mr. Andrew Lang on my "Testimony of Tradition" and
"Underground Life." The already excessive length of this Introduction
prevents me from now referring more particularly to these observations,
as I should otherwise have done. In the meantime, however, I beg to
refer Mr. Lang to the present work, and to ask him whether he thinks the
statements there quoted substantiate his conception of the _Fir Sidhe_
as a deathless people, occupying some region "unknown of earth."
