people of
Mongolian race, or those yellow peoples more or less related to them.

The literature of the kiss is extensive. So far, however, as that
literature is known to me, the following list includes everything that may
be profitably studied: Darwin, _The Expression of the Emotions_; Ling
Roth, "Salutations," _Journal of the Anthropological Institute_, November,
1889; K. Andree, "Nasengruss," _Ethnographische Parallelen_, second
series, 1889, pp. 223-227; Alfred Kirchhoff, "Vom Ursprung des Kuesses,"
_Deutsche Revue_, May, 1895; Lombroso, "L'Origine du Baiser," _Nouvelle
Revue_, 1897, p. 153; Paul d'Enjoy, "Le Baiser en Europe et en Chine,"
_Bulletin de la Societe d'Anthropologie_, Paris, 1897, fasc. 2. Professor
Nyrop's book, _The Kiss and its History_ (translated from the Danish by
W.F. Harvey), deals rather with the history of the kiss in civilization
and literature than with its biological origins and psychological
significance.

FOOTNOTES:

[196] E. Selous, _Bird Watching_, 1901, p. 191. This author adds: "It
seems probable indeed that the conferring a practical benefit of the kind
indicated may be the origin of the caress throughout nature."

[197] Tylor terms the kiss "the salute by tasting," and d'Enjoy defines it
as "a bite and a suction"; there seems, however, little evidence to show
that the kiss contains any gustatory element in the strict sense.

affection.

Swahili the kiss is practiced, but exclusively between married people and
with very young children. Velten believes they learned it from the Arabs.
