ture to secure a
fruitful union when the female is in readiness, but not an indication
for constant or frequent use.

7. The time of sexual congress is always determined by the condition
and desires of the female.

An additional fact, as stated by physiologists, is that, under normal
conditions, the human female experiences sexual desire immediately
after menstruation more than at any other time. It has, indeed, been
claimed that at this period only does she experience the true sexual
instinct unless it is abnormally excited by disease or otherwise.

From these facts the following conclusions must evidently be drawn:--

1. The fact that in all animals but the human species the act can be
performed only when reproduction is possible, proves that in the animal
kingdom in general the sole object of the function is reproduction.
Whether man is an exception, must be determined from other
considerations.

2. The fact that the males of other animals besides man in which the
sexual organs are in a state of constant development do not exercise
those organs except for the purpose of reproduction, is proof of the
position that the constant development in man is not a warrant for their
constant use.

3. The general law that the reproductive act is performed only when
desired by the female, is sufficient ground for supposing that such
should be the case with the human species also.

The opinions of writers of note are given in the following quotations:--

"The approach of the sexes is, in its purest condition, the result of
a natural instinct, the end of which is the reproduction of the species.
Still, however, we are far from saying that this ultimate result is,
in any proportion of cases, the actual thought in the minds of the
parties engaged."

"The very lively solicitations which spring from the genital sense,
have no other end than to insure the perpetuity of the race."[12]

[Footnote 12: Dr. Gardner.]

"Observation fully confirms the views of inductive philosophy; for it
proves to us that coitus, exercised otherwise than under the
inspirations of honest instinct, is a cause of disease in both sexes,
and of danger to the social order."[13]

[Footnote 13: Mayer.]

"It is incredible that the act of bringing men into life, that act of
humanity, without contradiction of the most importance, should be the
one of which there should have been the least supposed necessity for
regulation, or which has been regulated the
