p. 334) has some remarks on a somewhat similar tendency sometimes observed
in dogs and horses.

[192] Kistemaecker, as quoted by Bloch (_Beitraege, etc._, ii. p. 340),
alludes in this connection to the dark clothes of men and to the tendency
of women to wear lighter garments, to emphasize the white underlinen, to
cultivate pallor of the face, to use powder. "I am white and you are
brown; ergo, you must love me"; this affirmation, he states, may be found
in the depths of every woman's heart.

[194] In _Man and Woman_ (fourth edition, p. 65) I have referred to a
curious example of this tendency to opposition, which is of almost
worldwide extent. Among some people it is, or has been, the custom for the
women to stand during urination, and in these countries it is usually the
custom for the man to squat; in most countries the practices of the sexes
in this matter are opposed.

[195] It is sufficient to quote one example. At the end of the sixteenth
century it was a serious objection to the fashionable wife of an English
Brownist pastor in Amsterdam that she had "bodies [a bodice or corset]
tied to the petticoat with points [laces] as men do their doublets and
their hose, contrary to I Thess., v, 22, conferred with Deut. xxii, 5; and
I John ii, 16."

Summary of the Conclusions at Present Attainable in Regard to the Nature
of Beauty and its Relation to Sexual Selection.

The consideration of vision has led us into a region in which, more
definitely and precisely than is the case with any other sense, we can
observe and even hope to measure the operation of sexual selection in man.
In the conception of feminine beauty we possess an instrument of universal
extension by which it seems possible to measure the nature and extent of
such selection as exercised by men on women. This conception, with which
we set out, is, however, by no means so precise, so easily available for
the attainment of sound conclusions, as at first it may seem to be.

It is true that beauty is not, as some have supposed, a mere matter of
caprice. It rests in part on (1) an objective basis of aesthetic character
which holds all its variations together and leads to a remarkable
approximation among the ideals of feminine beauty cherished
