There are many varieties of feeling--as the feelings of
hunger, thirst, cold, hardness, etc. Many of these feelings are
excited by agents that act upon the exterior of the body, such as solid
substances of every kind, heat, and various chemical irritants. These
latter feelings are called _passions_.

Those passions which owe their existence chiefly to the state of the
brain, or to causes acting directly upon the brain, are called the moral
passion. They are grief, anger, love, etc. They consist of sentient
actions, which commence in the brain and extend to the nerves in the
region of the stomach, etc. But when the cause of the internal feeling
of passion is seated in some organ remote from the brain, as in the
stomach, genital organs, etc. , the sentient action which constitutes the
passion commences in the nerves of such organ and extends to the brain,
and the passion is called an _appetite, instinct, or desire_. Some
of these passions are natural, as hunger, thirst, the reproductive
instinct, the desire to urinate, etc. Others are gradually acquired by
habit A _hankering_ for stimulants, as spirits, opium and tobacco, is
one of these.

Such is the nature of things that our most vivid and agreeable
sensations cannot be excited under all circumstances, nor beyond a
certain extent under any circumstances, without giving rise in one
way or another to an amount of disagreeable consciousness or misery,
exceeding the amount of agreeable consciousness which attends such
ill-timed or excessive gratification. To excite agreeable sensations to
a degree not exceeding this certain extent is temperance; to excite
them beyond this extent is intemperance; not to excite them at all is
mortification or abstinence. This certain extent varies with different
individuals, according to their several circumstances, so that what
would be temperance in one person may be intemperance in another.

To be free from disagreeable consciousness is to be in a state which,
compared with a state of misery, is a happy state; yet absolute
happiness does not exist in the absence of misery, if it does, rocks are
happy. It consists, as aforesaid, in agreeable consciousness. That which
enables a person to excite or maintain agreeable consciousness is
not happiness; but the _idea_ of having such in one's possession is
agreeable, and of course is a portion of happiness. Health and wealth go
far in enabling a person to excite and maintain agreeable consciousness.
That which gives rise to agreeable consciousness is _good_, and we
desire it. If we use it intemperately, such use is bad, but the thing
itself is still good. Those acts (and intentions are acts of that part
of man which intends) of human beings which tend to the promotion of
happiness are good, but they are also called _virtuous_, to distinguish
them from other things of the same tendency. There is nothing for the
word _virtue_ to signify, but virtuous actions. Sin signifies nothing
but sinful actions, and sinful, wicked, vicious, or bad actions are
those which are productive of more misery than happiness.

When an individual gratifies any of his instincts in a _temperate_
degree, he adds an item to the sum total of human happiness, and causes
the amount of human happiness to exceed the amount of misery farther
than if he had not enjoyed himself, therefore it is virtuous, or, to
say the least, it is not vicious or sinful for him to do so. But it must
ever be remembered that this temperate degree depends on circumstances;
that one person's health, pecuniary circumstances, or social relation
may be such that it would cause more misery than happiness for him to do
an act which being done by a person under different circumstances would
cause more happiness than misery. Therefore, it would be right for the
latter to perform such act, but not for the former.

Again: owing to his _ignorance_, a man may not be able to gratify a
desire without causing misery (wherefore it would be wrong for him to
do it), but with knowledge of means to prevent this misery, he may so
gratify it that more pleasure than pain will be the result of the act,
in which case the act, to say the least, is justifiable. Now, therefore,
it is virtuous, nay, it is the _duty_, for him who has a knowledge of
such means, to convey it to those who have it not, for by so doing he
furthers the cause of human happiness.

Man by nature is endowed with the talent of devising means to remedy
or prevent the evils that are liable to arise from gratifying our
appetites; and it is as much the duty of the physician to inform
mankind of the means to prevent the evils that are liable to arise from
gratifying the productive instinct as it is to inform them how to keep
clear of the gout or dyspepsia. Let not the old ascetic say we ought
not to gratify our appetites any further than is necessary to maintain
health and to perpetuate the species. Mankind will not so abstain,
and if any means to prevent the evils that may arise from a farther
gratification can be devised, they _need not_. Heaven has not only given
us the capacity of greater enjoyment, but the talent of devising means
to prevent the evils that are liable to arise therefrom, and it becomes
us, "with thanksgiving," to make the most of them.




FRUITS OF PHILOSOPHY.




CHAPTER I. TO LIMIT AT WILL THE NUMBER OF THEIR OFFSPRING

Showing how desirable it is, both in a political and a social point
of view, for mankind to be able to limit at WILL THE NUMBER OF
THEIR OFFSPRING, WITHOUT SACRIFICING THE PLEASURE THAT ATTENDS THE
GRATIFICATION OF THE REPRODUCTIVE INSTINCT.

First. ---_In a political point of view_. --If population be not
restrained by some great physical calamity, such as we have reason to
hope will not hereafter be visited upon the children of men, or by some
_moral restraint_, the time will come when the earth cannot support
its inhabitants. Population unrestrained will double three times in a
century. Hence, computing the present population of the earth at 1,000
millions, there would be at the end of 100 years from the present time,
8,000 millions.

At the end of 200 years, 64,000 millions.

" " 300 " 512,000 "

And so on, multiplying by eight for every additional hundred years.
So that in 500 years from the present time there would be thirty-two
thousand seven hundred and sixty eight times as many inhabitants as at
present. If the natural increase should go on without check for 1,500
years, one single pair would increase to more than _thirty-five thousand
one hundred and eighty-four_ times as many as the present population of
the whole earth!

Some check then there must be, or the time will come when millions will
be born but to suffer and to perish for the necessaries of life. To what
an inconceivable amount of human misery would such a state of things
give rise! And must we say that vice, war, pestilence and famine are
desirable to prevent it? Must the friends of temperance and domestic
happiness stay their efforts? Must peace societies excite to war
and bloodshed? Must the physician cease to investigate the nature
of contagion, and to search for the means of destroying its baneful
influence? Must he that becomes diseased be marked as a victim to die
for public good, without the privilege of making an effort to restore
him to health? And in case of a failure of crops in one part of the
world, must the other parts withhold the means of supporting life that
the far greater evil of excessive population throughout the world may be
prevented? Can there be no effectual moral restraint, attended with far
less human misery than such physical calamities as these? Most surely
there can. But what is it? Malthus, an English writer on the subject of
population, gives us none but celibacy to a late age. But how foolish
it is to suppose that men and women will become as monks and nuns during
the very holiday of their existence, and abjure during the fairest
years of life the nearest and dearest of social relations, to avert
a catastrophe which they and perhaps their children will not live to
witness. But, besides being ineffectual, or if effectual, requiring a
great sacrifice of enjoyment, this restraint is highly objectionable
on the score of its demoralizing tendency. It would give rise to a
frightful increase of prostitution, of intemperance and onanism, and
prove destructive to health and moral feelings. In spite of preaching,
human nature will ever remain the same; and that restraint which forbids
the gratification of the reproductive instinct will avail but little
with the mass of mankind. The checks to be hereafter mentioned are
the only moral restraints to population known to the writer that are
unattended with serious objections.

Besides starvation, with all its accompanying evils, overpopulation is
attended with other public evils, of which may be mentioned, ignorance
and slavery. Where the mass of the people must toil incessantly to
obtain support, they must remain ignorant; and where ignorance prevails,
tyranny reigns. *

* The scientific part of Malthus' Doctrine of Population is
not very clearly or correctly given in the above passages.
His great theory, now or generally held by the most eminent
political economists, is that the increase of population is
always powerfully checked in old countries by the difficulty
in increasing the supply of food; that the existing evils of
poverty and low wages are really at bottom caused by this
check, and are brought about by the pressure of population
on the soil, and the continual overstocking of the labor
markets with laborers; and hence that the only way in which
society can escape from poverty, with all its miseries, is
by putting a strong restraint on their natural powers of
multiplication. "It is not in the nature of things," he
says, "that any permanent and general improvement in the
condition of the poor can be effected without an increase in
the preventive checks to population. "--G. R.

Second--_In a social point of view_. --"Is it not notorious that the
families of the married often increase beyond which a regard for the
young beings coming into the world, and the happiness of those who give
them birth, would dictate. In how many instances does the hard-working
father, and more especially the mother, of a poor family remain slave
throughout their lives, tugging at the oar of incessant labor, toiling
to live, and living to toil; when, if their offspring had been limited
to two or three only, they might have enjoyed comfort and comparative
affluence? How often is the health of the mother, giving birth every
year to an infant--happy if it be not twins--and compelled to toil on,
even at those times when nature imperiously calls for some relief from
daily drudgery,--how often is the mother's comfort, health, nay, even
her life, thus sacrificed? Or if care and toil have weighed down the
spirit, and at length broken the health of the father; how often is
the widow left unable, with the most virtuous intentions, to save her
fatherless offspring from becoming degraded objects of charity, or
profligate votaries of vice!

"Nor is this all. Many women are so constituted that they cannot give
birth to healthy, sometimes not to living children. Is it desirable,
is it moral, that such women should become pregnant? Yet this is
continually the case. Others there are who ought never to become
parents; because, if they do, it is only to transmit to their offspring
grievous hereditary diseases, which render such offspring mere subjects
of misery throughout their sickly existence. Yet such women will not
lead a life of celibacy. They marry. They become parents, and the sum of
human misery is increased by their doing so. But it is folly to expect
that we can induce such persons to live the lives of Shakers. Nor is it
necessary; all that duty requires of them is to refrain from becoming
parents. Who can estimate the beneficial effect which a rational
moral restraint may thus have on the health and beauty and physical
improvement of our race throughout future generations? "

Let us now turn our attention to the case of unmarried youth.

"Almost all young persons, on reaching the age of maturity, desire to
marry. That heart must be very cold, or very isolated, that does not
find some object on which to bestow its affections. Thus, early marriage
would be almost universal did not prudential consideration interfere.
The young man thinks, 'I cannot marry yet; I cannot support a family.
I must make money first, and think of a matrimonial settlement
afterwards. '

"And so he goes to making money, fully and sincerely resolved in a few
years to share it with her whom he now loves. But passions are strong
and temptations great. Curiosity, perhaps, introduces him into the
company of those poor creatures whom society first reduces to a
dependence on the most miserable of mercenary trades, and then curses
for being what she has made them. There his health and moral feelings
are alike made shipwreck. The affections he had thought to treasure up
for their first object are chilled by dissipation and blunted by excess.
He scarcely retains a passion but avarice. Years pass on--years of
profligacy and speculation--and his wish is accomplished, his fortune is
made. Where now are the feelings and resolve of his youth?

'Like the dew on the mountain,
Like the foam on the river,
Like the bubbles on the fountain,
They are gone--and forever. '

"He is a man of pleasure, a man of the world. He laughs at the romance
of his youth, and marries a fortune. If gaudy equipage and gay parties
confer happiness, he is happy. But if these be only the sunshine on
the stormy sea below, he is a victim to that system of morality which
forbids a reputable connection until the period when provision has been
made for a large expected family. Had he married the first object of his
choice, and simply delayed becoming a father until his prospects seemed
to warrant it, how different might have been his lot. Until men and
women are absolved from the fear of becoming parents, except when they
themselves desire it, they will ever form mercenary and demoralizing
connections, and seek in dissipation the happiness they might have found
in domestic life.

"I know that this, however common, is not a universal case. Sometimes
the heavy responsibilities of a family are incurred at all risks; and
who shall say how often a life of unremitting toil and poverty is the
consequence. Sometimes, if even rarely, the young mind does hold its
first resolves. The youth plods through years of cold celibacy and
solitary anxiety, happy if, before the best hours of his life are gone
and its warmest feelings withered, he may return to claim the reward of
his forbearance and his industry. But even in this comparatively happy
case, shall we count for nothing the years of ascetic sacrifice at which
after happiness is purchased? The days of youth are not too many, nor
its affections too lasting. We may, indeed, if a great object require
it, sacrifice the one and mortify the other. But is this, in itself,
desirable? Does not wisdom tell us that such a sacrifice is a dead
loss--to the warm-hearted often a grievous one? Does not wisdom bid us
temperately enjoy the springtimes of life, 'while the evil day come not,
nor the years draw nigh, when we shall say we have no pleasure in them? '

"Let us say, then, if we will, that the youth who thus sacrifices the
present for the future, chooses wisely between the two evils, profligacy
and asceticism. This is true. But let us not imagine the lesser evil
to be good. It is _not_ good for man to be alone. It is for no man or
woman's happiness or benefit that they should be condemned to Shakerism.
It is a violence done to the feelings and an injury to the character.
A life of rigid celibacy, though infinitely preferable to a life of
dissipation, is yet fraught with many evils. Peevishness, restlessness,
vague longings and instability of character, are amongst the least of
these. The mind is unsettled, and the judgment warped. Even the very
instinct which is thus mortified assumes an undue importance, and
occupies a portion of the thoughts which does not of right or nature
belong to it, and which, during a life of satisfied affection, it would
not obtain. "

In many instances, the genital organs are rendered so irritable by the
repletion to which unnatural continency gives rise, and by the much
thinking caused by such repletion, as to induce a disease known to
medical men by the name of _Gonorrhoea Dormientium_. It consists in
an emission or discharge of the semen during sleep. This discharge is
immediately excited in most instances by a lascivious dream, but such
dream is caused by the repletion and irritability of the genital organs.
It is truly astonishing to what a degree of mental anguish the disease
gives rise in young men. They do not understand the nature, or rather,
the cause of it. They think it depends on a weakness--indeed, the
disease is often called a "seminal weakness"--and that the least
gratification in a natural way would but serve to increase it.
Their anxiety about it weakens the whole system. This weakness they
erroneously attribute to the discharges; they think themselves totally
disqualified for entering into or enjoying the married state. Finally,
the genital and mental organs act and react upon each other so
perniciously as to cause a degree of nervousness, debility, emaciation
and melancholy--in a word, wretchedness that sets description at
defiance. Nothing is so effectual in curing this diseased state of
a body and mind in young men as marriage. All restraint, fear and
solicitude should be removed.

"Inasmuch, then, as the scruples of incurring heavy responsibilities
deter from forming moral connections and encourage intemperance and
prostitution, the knowledge which enables man to limit the number of his
offspring would, in the present state of things, save much unhappi-ness
and prevent many crimes. Young persons sincerely attached to each other,
and who might wish to marry, should marry early, merely resolving not
to become parents until prudence permitted it. The young man, instead
of solitary toil and vulgar dissipation, would enjoy the society and the
assistance of her he has chosen as his companion; and the best years of
life, whose pleasures never return, would not be squandered in riot, nor
lost through mortification. "*

* The passages quoted are from Robert Dale Owen's "Moral
Physiology. "




CHAPTER II. ON GENERATION

I hold the following to be important and undeniable troths: That every
man has a natural right both to receive and convey a knowledge of all
the facts and discoveries of every art and science, excepting such only
as may be secured to some particular person or persons by copyright or
patent; that a physical truth in its general effect cannot be a moral
evil; that no fact in physics or in morals ought to be concealed from
the inquiring mind.

Some may make a misuse of knowledge, but that is their fault; and it is
not right that one person should be deprived of knowledge, of spirits,
of razors, or of anything else which is harmless in itself and may be
useful to him, because another may misuse it.

The subject on generation is not only interesting as a branch of
science, but it is so connected with the happiness of mankind that it is
highly important in a practical point of view. Such, to be sure, is
the custom of the age, that it is not considered a proper subject to
investigate before a popular assembly, nor is it proper to attend the
calls of nature in a like place; yet they must and ought to be attended
to, for the good, the happiness of mankind require it; so, too, for like
reason, the subject of generation ought to be investigated until it be
rightly understood by all people, but at such opportunities as the
good sense of every individual will easily decide to be proper. This,
I presume to say, not simply upon the abstract principle that
all knowledge of Nature's workings is useful, and the want of it
disadvantageous, but from the known moral fact that ignorance of this
process has in many instances proved the cause of a lamentable "mishap,"
and more especially as it is essential to the attainment of the great
advantage, which it is the chief object of this work to bestow upon
mankind.

People generally, as it was the case with physicians until late years,
entertain a very erroneous idea of what takes place in the conception.
Agreeably to this idea the "check" which I consider far preferable
to any other, would not be effectual, as would be obvious to all.
Consequently, entertaining this idea, people would not have due
confidence in it. Hence, it is necessary to correct a long-held and
widely extended error. But this I cannot expect to do by simply saying
it is an error. Deeply rooted and hitherto undisputed opinions are not
so easily eradicated. If I would convince any one that the steps in one
of the most recondite processes of nature are not such as he has always
believed, it will greatly serve my purpose to show what these steps are.
I must first prepare him to be reasoned with, and then reason the
matter all over with him. I must point out the facts which disprove his
opinion, and show that my own is unattended with difficulties.

But what can be more obvious than that it is absolutely impossible
to explain any process or function of the animal economy, so as to be
understood, before the names of the organs which perform this function
have been defined, that is, before the organs themselves have been
described. Now it is well known to every anatomist, and indeed it may
be obvious to all, that in describing any organ or system of organs,
we must always begin with some external and known parts, and proceed
regularly, step by step, to the internal and unknown. As in arithmetic,
"everything must be understood as you go along. "*

* This is an Americanism, which appears to us to convey a
false idea. If it refers to the cases used as illustrations,
Dr. Knowlton is more sparing in his use of them than either
Dr. Bull or Dr. Chavasse. --Publishers' Note.

Fully to effect the objects of this work, it is, therefore, a matter of
necessity that I give an anatomical description of certain parts--even
external parts--which some, but imagine what I have just said, might
think it useless to mention. It is not to gratify the idle curiosity of
the light-minded that this book is written; it is for _utility_ in the
broad and truly philosophical sense of the term; nay, farther, it shall
with the exception of here and there a little spicing*, have confined
to _practical utility_. I shall, therefore, endeaver to treat of the
subject in this chapter so as to be understood, without giving any
description of the male organs of generation; though I hold it an
accomplishment for one be able to speak of those organs, as diseases
often put them under the necessity of doing, without being compelled use
low and vulgar language. But I must briefly describe the female organs;
in doing which I must, of course, speak as do other anatomists and
physiologists; and whoever objects to this will discover more
affectation and prudery than good sense and good will to mankind.

The adipose, or fatty matter, immediately over the share bone, forms
a considerable prominence in females, which, at the age of puberty, is
covered with hair, as in males. This prominence is called Mons Veneris.

The exterior orifice commences immediately below this. On each side of
this orifice is a prominence continued from the mons veneris, which
is largest above and gradually diminishes as it descends. These two
prominences are called the Labia Externa, or external lips. Near the
latter end of pregnancy they become somewhat enlarged and relaxed, so
that they sustain little or no injury during parturition. Just within
the upper or anterior commissure, formed by the junction of these lips,
a little round oblong body is situated. The body is called the clitoris.
Most of its length is bound down, as it were, pretty closely to the
bone; and it is of very variable size in different females. Instances
have occurred where it was so enlarged as to allow the female to have
venereal commerce with others; and in Paris this fact was once made a
public exhibition to the medical faculty. Women thus formed appear to
partake in their general form of the male character, and are called
hermaphrodites. The idea of human beings, called hermaphrodites, which
could be either father or mother, is, doubtless, erroneous. The clitoris
is analogous in its structure to the penis, and like it, is exquisitely
sensitive, being, as it is supposed, the principal seat of pleasure. It
is subject to erection or distension, like the penis, from like causes.

The skin which lines the internal surface of the external lips is folded
in such manner as to form two flat bodies, the exterior edges of which
are convex. They are called the nymphse. They extend downward, one on
each side, from the clitoris to near the middle of the external orifice,
somewhat diverging from each other. Their use is not very evident The
orifice of the urethra (the canal, short in females, which leads to the
bladder) is situated an inch or more farther inward than the clitoris,
and is a little protuberant.

Passing by the external lips, the clitoris, the nymphse and the orifice
of the urethra, we come to the membrane called the hymen. It is situated
just at, or a trifle behind the orifice of the urethra. It is stretched
across the passage, and were it a complete septum, it would close up the
anterior extremity of that portion of the passage which is called the
vagina. But the instances in which the septum or partition is complete
are very rare, there being, in almost all cases, an aperture either in
its center, or frequently in its anterior edge, giving the membrane the
form of a crescent Through this aperture passes the menstrual fluid.
Sometimes, however, this septum is complete, and the menstrual fluid
is retained month after month, until appearances and symptoms much
like those of pregnancy are produced, giving rise to perhaps unjust
suspicions. Such cases require the simple operation of dividing the
hymen. In many instances the hymen is very imperfect, insomuch that some
have doubted whether it is to be found in the generality of virgins.
Where it exists it is generally ruptured in the first intercourse of
the sexes, and the female is said to lose her virginity. In some
rare instances it is so very strong as not to be ruptured by such
intercourse, and the nature of the difficulty not being understood, the
husband has sued for a divorce. But everything may be put to rights by
a slight surgical operation. The parts here described are among those
called the external parts of generation.

The internal organs of generation consist in the female of the Vagina,
the Uterus, the Ovaries and their appendages.

The Vagina is a membranous canal commencing at the hymen and extending
to the uterus. It is a little curved, and extends backward and upward
between the bladder, which lies before and above it, and that extreme
portion of the bowels called the rectum, which lies behind it. The
coat of membrane which lines the internal surface of the vagina forms a
number of transverse ridges.
These are to be found only in the lower
or anterior half of the vagina, and they do not extend all round the
vagina, but are situated on its anterior and posterior sides, while
their lateral sides are smooth. I mention these ridges because a
knowledge of them may lead to a more effectual use of one of the checks
to be made known hereafter.

The uterus or womb is also situated between the bladder and the rectum,
but above the vagina. Such is its shape that it has been compared to
a pear with a long neck. There is, of course, considerable difference
between the body and the neck, the first being twice as broad as the
last. Each of these parts is somewhat flattened. In subjects of mature
age, who have been pregnant, the whole of the uterus is about two inches
and a half in length, and more than an inch and a half in breadth at the
broadest part of the body. It is near an inch in thickness. The neck of
the uterus is situated downward, and may be said to be inserted into
the upper extremity of the vagina. It extends down into the vagina the
better part of an inch. In the uterus is a cavity which approaches the
triangular form, and from which a canal passes down through the neck of
the uterus into the vagina. This cavity is so small that its sides are
almost in contact So that the uterus is a thick, firm organ for so small
a one. Comparing the cavity of the uterus to a triangle, we say the
upper side or line of this triangle is transverse with respect to the
body, and the other two lines pass downward and inward, so that they
would form an angle below, did they not before they meet take a turn
more directly downward to form the canal just mentioned. In each of the
upper angles there is an orifice of such size as to admit of a hog's
bristle. These little orifices are the mouths of two tubes, called the
Fallopian tubes, of which more will be said presently. The canal which
passes through the neck of the uterus, connecting the cavity of
this organ with that of the vagina, is about a quarter of an inch in
diameter. It is different from other ducts, for it seems to be a part
of the cavity from which it extends, inasmuch as when the cavity of the
uterus is enlarged in the progress of pregnancy, this canal is gradually
converted into a part of that cavity.

The lower extremity of the neck of the uterus is irregularly convex and
tumid. The orifice of the canal in it is oval, and so situated that it
divides the convex surface of the lower extremity of the neck in two
portions, which are called the lips of the uterus. The anterior is
thicker than the posterior. The orifice itself is called _os tincæ_ or
_os uteri_, or in English, the mouth of the womb. When the parts are in
a weak, relaxed state, the mouth or neck of the uterus is quite low, and
in almost all oases it may be reached by a finger introduced into the
vagina, especially by a second person, who carries the hand behind.

The Ovaries are two bodies of a flattened or oval form, one of which is
situated on each side of the uterus at a little distance from it, and
about as high up as where the uterus becomes narrow to form its neck.
The longest diameter of the ovarium is about an inch. Each ovarium has a
firm coat of membrane. In those who have not been pregnant, it contains
from ten to twenty _vesicles_, which are little round bodies, formed of
a delicate membrane, and filled with a transparent fluid. Some of
these vesicles are situated so near the surface of the ovarium as to
be prominent on its surface. They are of different sizes, the largest
nearly a quarter of a inch in diameter. *

* The vesicles here mentioned are the so-called Graafian
vesicles, or ovisacs, each of which contains in its interior
a little ovum or egg. In the human female the ovum is
extremely minute, so as only to be visible with the aid of a
lens. The Graafian vesicles are not limited to a certain
small number, as was formerly thought, but continue to be
formed in the ovaries, and to discharge at intervals mature
ova during the whole of the fruitful period. --G. R.

In those in whom conception has ever taken place, some of these vesicles
are removed, and in their place a cicatrix or scar is formed which
continues through life. However, the number of cicatrices does not
always correspond with the number of conceptions. They often exceed
it, and are sometimes found where conception has not been known to take
place. The Fallopian Tubes are two canals four or five inches in length,
proceeding from the upper angles of the cavity of the uterus, in a
transverse direction in respect to the body. Having so proceeded
for some distance they turn downward toward the ovaries. At their
commencement in the uterus they are very small, but they enlarge as much
as they progress. The large ends, which hang loose, terminate in open
mouths, the margins of which consist of fimbriated processes, and nearly
touch the ovaria.

We are now prepared to treat of conception. Yet, as menstruation is
closely connected with it, and as a knowledge of many things concerning
menstruation may contribute much to the well-being of females, for
whom this work is at least as much designed as for males, I shall first
briefly treat of this subject.

Menstruation. --When females arrive at the age of puberty they begin to
have a discharge once every month, by way of the vagina, of the color of
blood. This discharge is termed the menses. To have it is to menstruate.
The age at which menstruation commences varies with different
individuals, and also in different climates. The warmer the climate
the earlier it commences and ceases. In temperate climates it
generally commences at the age of fourteen or fifteen, and it ceases at
forty-four, or a little later. *

Whenever it commences the girl acquires a more womanly appearance. It
is a secretion of the uterus, or, in other words, the minute vessels
distributed to the inner coat of uterus, select as it were, from the
blood, and pour out in a gradual manner the materials of this fluid. It
has one of the properties, color, of blood, but it does not coagulate,
or separate into different parts like blood, and cannot properly be
called blood. **

* Dr. Chavasse, on p. 94 of his "Advice to a Wife"
published by W. H. Smith & Son gives instances of very
early menstruation and consequent fecundity. --Publishers'
note,

** "The menstrual discharge," says Dr. Kirkes, "consists of
blood effused from the inner surface of the uterus, and
mixed with mucus from the uterus, vagina, and the external
parts of the generative apparatus. Being diluted by this
admixture, the menstrual blood coagulates less perfectly
than ordinary blood; and the frequent acidity of the vaginal
mucus tends still further to diminish its coagulability. "--
Handbook of Physiology, 8th ed. , p. 727, 1874. --G. R.

When this discharge is in all respects regular, it amounts in most
females to six or eight ounces, and from two to four days' continuance.
During its continuance the women is said to be unwell, or out of order.
Various unpleasant feelings are liable to attend it; but when it is
attended with severe pain, as it not infrequently is, it becomes a
disease, and the woman is not likely to conceive until it is cured.
During the existence of the "turns," or "monthlies," as they are often
called, indigestible food, dancing in warm rooms, sudden exposure
to cold or wet, and mental agitations, should be avoided as much as
possible. The "turns" do not continue during pregnancy, nor nursing,
unless nursing be continued after the "turns" recommence. Some women, it
is true, are subject to a slight hemorrhage that sometimes occurs with
considerable regularity during pregnancy, and which has led them to
suppose they have their turns at such times; but it is not so; the
discharge at such times is real blood. *

The use of the menstrual discharge seems to be to prepare the uterine
system for conception. For females do not become pregnant before
they commence, nor after they cease having turns; nor while they are
suppressed by some disease, by cold or by nursing. Some credible women,
however, have said that they become pregnant while nursing, without
having had any turn since their last lying-in. It is believed that in
these oases they had some discharge, colorless, perhaps, which they did
not notice, but which answered the purposes of the common one. Women
are not nearly so likely to conceive during the week before a monthly
as during the week immediately after. * But although the use of this
secretion seems to be to prepare for conception, it is not to be
inferred that the reproductive instinct ceases at the "turn of life,"
or when the woman ceases to menstruate. On the contrary, it is said that
this passion often increases at this period, and continues in a greater
or less degree to an extreme age.

Conception. --The part performed by the male in the reproduction of the
species consists in exciting the organism of the female, and depositing
the semen in the vagina. Before I inquire what takes place in the
females I propose to speak of the semen.

This fluid, which is secreted by the testicles, may be said to possess
three kinds of properties, physical, chemical, physiological. Its
physical properties are known to every one--it is a thickish, nearly
opaque fluid, of a peculiar odor, saltish taste, etc. As to its chemical
properties, it is found by analysis to consist of 900 parts of water,
60 of animal muscilage, 10 of soda, 30 of phosphate of lime. Its
physiological property is that of exciting the female genital organs in
a peculiar manner.

When the semen is examined by microscope, there can be distinguished a
multitude of small animalculæ, which appear to have a rounded head and a
long tail. These animalculæ move with a certain degree of rapidity. They
appear to avoid the light and to delight in the shade. Leeuwenhoek, if
not the discoverer of the seminal animalculse, was the first who brought
the fact of their existence fully before the public. With respect to
their size, he remarked that ten thousand of them might exist in a space
not larger than a grain of sand. They have a definite figure, and are
obviously different from the animalculse found in any other fluid. *

* See Dr. Carpenter's "Animal Physiology," p. 558 (published
by H. G. Bonn); Nichol's "Human Physiology," pp. 253-255
(published by Trubner & Co. )--Publishers' note.

Leeuwenhoek believed them to be the beginnings of future animals--that
they are of different sexes, upon which depends the future sex of the
foetus. Be this as it may, it appears to be admitted on all hands that
the animalculæ are present in the semen of the various species of
male animals, and that they cannot be detected when either from age or
disease the animals are rendered sterile. "Hence," says Bostock, "we can
scarcely refuse our assent to the position that these animalculæ are
in some way or other instrumental to the production of the foetus. "
The secretion of the semen commences at the age of puberty. Before this
period the testicles secrete a viscid, transparent fluid, which has
never been analyzed, but which is doubtless essentially different from
semen. The revolution which the whole economy undergoes at this period,
such as the tone of the voice, and development of hairs, the beard, the
increase of the muscles and bones, etc. , is intimately connected with
the testicles and the secretion of this fluid. * "Eunuchs preserve the
same form as in childhood; their voice is effeminate, they have no
beard, their disposition is timid; and finally their physical and moral
character very nearly resembles that of females. Nevertheless, many of
them take delight in venereal intercourse, and give themselves up with
ardor to a connection which must always prove unfruitful. "**

The part performed by the female in the reproduction of the species is
far more complicated than that performed by the male. It consists, in
the first instance, in providing a substance which, in connection
with the male secretion, is to constitute the foetus; in furnishing a
suitable situation in which the foetus may be developed; in affording
due nourishment for its growth; in bringing it forth, and afterward
furnishing it with food especially adapted to the digestive organs of
the young animal. Some parts of this process are not well understood,
and such variety of hypotheses have been proposed to explain them that
Drelincourt, who lived in the latter part of the seventeenth century, is
said to have collected two hundred and sixty hypotheses of generation.

It ought to be known that women have conceived when the semen was merely
applied to the parts anterior to the hymen, as the internal surface
of the external lips, the nymphæ, etc. This is proved by the fact that
several cases of pregnancy have occurred when the hymen was entire. The
fact need not surprise us, for, agreeable to the theory of absorption,
we have to account for it only to suppose that some of the absorbent
vessels are situated anterior to the hymen--a supposition by no means
unreasonable.

There are two peculiarities of the human species respecting conception
which I will notice. First, unlike other animals they are liable, and
for what has been proved to the contrary, equally liable--to conceive
at all seasons of the year. Second, a woman rarely, if ever, conceives
until after having several sexual connections; nor does one connection
in fifty cause conception in the matrimonial state, where the husband
and wife live together uninterruptedly. Public women rarely conceive,
owing probably to a weakened state of the genital system, induced by too
frequent and promiscuous intercourse.

It is universally agreed, that some time after a fruitful connection,
a vesicle (two in case of twins) of one or the other ovary becomes so
enlarged that it bursts forth from the ovary and takes the name of
ovum, which is taken up, or rather received, as it bursts forth, by the
fimbriated extremity of the Fallopian tube, and is then conducted along
the tube into the uterus, to the inner surface of which it attaches
itself. *

* Since Dr. Knowlton's work was written, the very important
fact has been discovered that ova are periodically
discharged from the ovaries in the human female and other
animals, not in consequence of fruitful connection having
taken place, as was formerly believed, but quite
independently of intercourse with the male. Such a discharge
of ova occurs in the lower animals at the time of heat or
rut, and in women during menstruation. At each menstrual
period, a Graafian vesicle becomes enlarged, bursts, and
lets the ovum which it contains escape into the Fallopian
tube, along which it passes to the uterus. "It has long been
known," says Dr. Kirke, "that in the so-called oviparous
animals, the separation of ova from the ovary may take place
independently of impregnation by the male, or even of sexual
union. And it is now established that a like maturation and
discharge of ova, independently of coition, occurs in
Mammalia, the periods at which the matured ova are separated
from the ovaries and received into the Fallopian tubes being
indicated in the lower Mammalia by the phenomena of _heat_
or _rut_; in the human female by the phenomena of
_menstruation_. Sexual desire manifests itself in the human
female to a greater degree at these periods, and in the
female of mammiferous animals at no other time. If the union
of the sexes takes place, the ovum may be fecundated, and if
no union occur, it perishes. From what has been said it may
therefore be concluded that the two states, heat and
menstruation, are analogous, and that the essential
accompaniment of both is the maturation and extrusion of
ova. "--"Handbook of Physiology," page 724. --G. R.

Here it becomes developed into a full grown foetus, and is brought forth
about forty-two weeks from the time of conception by a process termed
parturition. But one grand question is, how the semen operates itself,
or any part thereof reaches the ovary, and if so, in what way it is
conveyed to them. It was long the opinion that the semen was ejected
into the uterus in the act of coition, and that it afterward, by some
unknown means, found its way into and along the Fallopian tubes to the
ovary. But there are several facts which weigh heavily against this
opinion, and some that entirely forbid it. In the first place, there are
several well attested instances in which impregnation took place while
the hymen remained entire, where the vagina terminated in the rectum,
where it was so contracted by a cicatrix as not to admit the penis. In
all these cases the semen could not have been lodged anywhere near
the mouth of the uterus, much less ejected into it. Secondly, it has
followed a connection where from some defect in the male organs, as the
urethra terminating some inches behind the end of the penis, and it is
clear that the semen could not have been injected into the uterus, nor
even near its mouth. Third, the neck of the unimpregnated uterus is so
narrow as merely to admit a probe, and is filled with a thick tenacious
fluid, which seemingly could not be forced away by any force which the
male organ possesses of ejecting the semen, even if the mouth of the
male urethra were in opposition with that of the uterus. But fourth, the
mouth of the uterus is by no means fixed. By various causes it is made
to assume various situations, and probably the mouth of the urethra
rarely comes in contact with it.

Fifth. "The tenacity of the male semen is such as renders its passage
through the small aperture in the neck of the uterus impossible, even by
a power of force much superior to that which we may rationally suppose
to reside in the male organs of generation. "

Sixth. "Harvey and DeGraaf dissected animals at almost every period
after coition for the express purpose of discovering the semen, but were
never able to detect the smallest vestige of it in the uterus in any one
instance. "*

* Dewees' Essay on Superfoetation. --Author's note.

Aware of the insurmountable objection to this view of the manner
in which the semen reaches the ovary, it has been supposed by some
physiologists that the semen is absorbed from the vagina into the great
circulating system, where it is mixed, of course, with the blood, and
goes the whole round of the circulation subject to the influence of
those causes which produce great changes in the latter fluid.

To this hypothesis it may be objected, that while there is no direct
evidence in support of it, it is exceedingly unreasonable, inasmuch
as we can scarcely believe that the semen can go the whole round of
circulation, and then find its way to the ovary in such a pure unaltered
state as the experiments of Spallanzani prove it must be in, that it may
impregnate.

A third set of theorists have maintained that an imperceptible
something, which they have called _aura seminalis_, passes from the
semen lodged in the vagina to the ovary, and excites those actions which
are essential to the development of an ovum. Others, again, have told us
that it is all done by sympathy. That neither the semen nor any volatile
part of it finds its way to the ovary; but that the semen excites the
parts with which it is in contact in a peculiar manner, and by the law
of animal economy, termed sympathy, or consent of parts, a peculiar
action commences in the ovary, by which an ovum is developed.

To both these conjectures it may be objected that they have no other
foundation but the supposed necessity of adopting them, to account for
the effect of impregnation; and, further, they "make no provision for
the formation of mules; for the peculiarities of, and likeness to,
parents, and for the propagation of predisposition to disease, from
parent to child; for the production of mulattoes," etc.

A fifth, and to me far more satisfactory view of the subject than any
other, is that advanced by our distinguished countryman, Dr. Dewees, of
Philadelphia. It appears to harmonize with all known facts relating
to the conception and something from analogy may also be drawn in its
favor. It is this, that there is a set of absorbent vessels, leading
directly from the inner surface of the _labia externa_ and the vagina,
to the ovaries, the whole office of which vessels is to absorb the semen
and convey it to the ovaries. * I do not know that these vessels have
yet been fully discovered, but in a note on the sixteenth page of his
"Essays on Various Subjects," the doctor says: "The existence of these
vessels is now rendered almost certain, as Dr. Gartner, of Copenhagen,
has discovered a duct leading from the ovary to the vagina. "

* This view is not held at the present day. The commonly
received doctrine now is that the seminal fluid enters the
uterus, whether during the intercourse or after it, and
passes along the Fallopian tubes to the ovaries; and that
fecundation takes place at some point of this course, most
frequently in the tubes, but also at times in the ovary
itself, or even, perhaps, in the uterus. It is essentially
necessary for fecundation that the spermatozoa should come
into actual contact with the ovum. "That the spermatozoa
make their way toward the ovarium, and fecundate the ovum
either before it entirely quits the ovisac or very shortly
afterward," says Dr. Carpenter, "appears to be the general
rule in regard to the Mammalia; and their power of movement
must obviously be both vigorous and long continued to enable
them to traverse so great an extent of mucous membrane,
especially when it is remembered that they ascend in
opposition to the direction of the ciliary movement of the
epithelial cells and to the downward peristaltic action of
the Fallopian tubes. * * * There can be no doubt that it is
the contact of the spermatozoa with the ovum, and in the
changes which occur as the immediate consequence of that
contact, that the act of fecundation essentially consists. "
--"Principles of Human Physiology," 8th ed. , p. 961,1876. --G. R.

Another question of considerable moment relating to generation is from
which parent are the first rudiments of the foetus derived.

The earliest hypothesis with which we are acquainted, and which has
received the support of some of the most eminent of the moderns,
ascribes the original formation of the foetus to the combination of
particles of matter derived from each of the parents. This hypothesis
naturally presents itself to the mind as the obvious method of
explaining the necessity for the cooperation of the two sexes, and the
resemblance in external form, and even in mind and character, which the
offspring often bears to the male parent. "The principal objections,"
says Bostock, "to his hypothesis, independent of the want of any direct
proof of a female seminal fluid, are of two descriptions, those which
depend upon the supposed impossibility of unorganized matter forming
an organized being, and those which are derived from observations and
experiments of Haller and Spallanzani, which they brought forward in
support of their theory of pre-existent germs. "

In relation to these objections I remark, first those whose experience
has been with hale females, I suspect, can have no doubt but that the
female organism increases like that of the male, until an emission of
fluid of some kind or other takes place. But whether this secretion may
properly be called semen, whether any part of it unites with the male
semen in forming the rudiments of the foetus, is another question. For
my part I am inclined to the opinion that it does not. * I rather regard
it as the result of exalted excitation, analogous to the increased
secretion of other organs from increased stimulation; and if it may be
for any object or use, as it probably is, it is that of affording
nature a means of relieving herself; or, in other words, of quieting the
venereal passion. If this passion, being once roused, could not by some
means or other be calmed, it would command by far too great a portion of
our thoughts, and with many constitutions the individuals, whether male
or female, could not conduct themselves with due decorum. One fact which
leads me to think that the female secretion in the act of coition is not
essential to impregnation is, that many females have conceived, if their
unbiased testimony may be relied on, when they experienced no pleasure.
In these cases it is more than probable that there was no orgasm, nor
any secretion or emission of fluid on the part of the female.

* With regard to this secretion in the female, which has
nothing of a seminal character, Dr. Carpenter observes: "Its
admixture with the male semen has been supposed to have some
connection with impregnation; but no proof whatever has been
given that any such admixture is necessary. "--"Human
Physiology," p. 991. --G. R.

As to the objection of the supposed impossibility of unorganized matter
forming an organized being, I do not believe such a thing takes place,
even if we admit that "the original formation of the foetus is a
combination of particles of matter derived from each of the parents. "
What do, or rather what ought we to mean by organized matter?
