[Traces in marriage customs of the belief that women can be impregnated
by the sun.]

Even in the marriage customs of various races we may perhaps detect
traces of this belief that women can be impregnated by the sun. Thus
amongst the Chaco Indians of South America a newly married couple used
to sleep the first night on a mare's or bullock's skin with their heads
towards the west, "for the marriage is not considered ratified till the
rising sun shines on their feet the succeeding morning."[175] At old
Hindoo marriages the first ceremony was the "Impregnation-rite"
(_Garbh[=a]dh[=a]na_); during the previous day the bride was made to
look towards the sun or to be in some way exposed to its rays.[176]
Amongst the Turks of Siberia it was formerly the custom on the morning
after the marriage to lead the young couple out of the hut to greet the
rising sun. The same custom is said to be still practised in Iran and
Central Asia under a belief that the beams of the rising sun are the
surest means of impregnating the new bride.[177]

[Belief in the impregnation of women by the moon.]

And as some people think that women may be gotten with child by the sun,
so others imagine that they can conceive by the moon. According to the
Greenlanders the moon is a young man, and he "now and then comes down to
give their wives a visit and caress them; for which reason no woman dare
sleep lying upon her back, without she first spits upon her fingers and
rubs her belly with it. For the same reason the young maids are afraid
to stare long at the moon, imagining they may get a child by the
bargain."[178] Similarly Breton peasants are reported to believe that
women or girls who expose their persons to the moonlight may be
impregnated by it and give birth to monsters.[179]

Sec. 8. _Reasons for the Seclusion of Girls at Puberty_

[The reason for the seclusion of women at puberty is the dread of
menstruous blood.]

The motive for the restraints so commonly imposed on girls at puberty is
the deeply engrained dread which primitive man universally entertains of
menstruous blood. He fears it at all times but especially on its first
appearance; hence the restrictions under which women lie at their first
menstruation are usually more stringent than those which they have to
observe at any subsequent recurrence of the mysterious flow. Some
evidence of the fear and of the customs based on it has been cited in
