matron is said greatly to resent the
intrusion of another male.[49]

In insects, as in the higher animals, and as in man, sexual
association takes many different forms. But obviously I must not
linger over these early types of love. My object is to bring forward
examples, which seem to me useful as preliminary studies to throw
light on the origin of sex-passion, and proving that the love-process
throughout the whole of life is identical. Those who are acquainted
with the work of Fabre, "The Insects' Homer," will have no difficulty
in accepting this. The studies he has given us of wonderful behaviour
of insects, their arts and crafts, their courtships and marriages,
their domestic and social relationships, opens up a new drama of
animal life.

[40] There are some who believe that the higher animals pass through a
state of embryonic hermaphroditism, but decisive proof of this is
wanting. In this connection the structural resemblance of the male and
female sexual organs should be noticed; in each sex there is a
complete but rudimentary set of parallels to the organs of the other
sex. This primitive and fundamental unity of the male and female sex
organs is very significant. Indeed, the whole question of
hermaphroditism is one of deep suggestion when these embryological
facts are brought into relation with the abnormalities which occur in
the expression of the sexual impulses. See _Evolution of Sex_, chapter
on "Hermaphroditism," pp. 65-80; also Bloch, _Sexual Life of Our
Times_, pp. 11-12, 551-554. Wieninger's _Sex and Character_, pp. 6, 7,
13, 45, is also interesting.

[41] A similar condition has been noted among butterflies, where, in
some cases, differences in the colouring of the wings on two sides has
been found to correspond to an internal co-existence of the male and
female sex-organs. It seems probable that this interesting phenomenon
of abnormal hermaphroditism is of much commoner occurrence than the
cases that have been recorded (_Evolution of Sex_, p. 67).
