How to beget a male or female child; and of the Embryo and perfect Birth; and the fittest time for the copula.

When a young couple are married, they naturally desire children; and therefore adopt the means that nature has appointed to that end. But notwithstanding their endeavours they must know that the success of all depends on the blessing of the Gods: not only so, but the sex, whether male or female, is from their disposal also, though it cannot be denied, that secondary causes have influence therein, especially two. First, the general humour, which is brought by the arteria praeparantes to the testes, in form of blood, and there elaborated into seed, by the seminifical faculty residing in them. Secondly, the desire of coition, which fires the imagination with unusual fancies, and by the sight of brisk, charming beauty, may soon inflame the appetite. But if nature be enfeebled, some meats must be eaten as will conduce to afford such aliment as makes the seed abound, and restores the exhaustion of nature that the faculties may freely operate, and remove impediments obstructing the procreating of children. Then, since diet alters the evil state of the body to a better, those subject to barrenness must eat such meats as are juicy and nourish well, making the body lively and full of sap; of which faculty are all hot moist meats. For, according to Galen, seed is made of pure concocted and windy superfluity of blood, whence we may conclude, that there is a power in many things, to accumulate seed, and also to augment it; and other things of force to cause desire, as hen eggs, pheasants, woodcocks, gnat-snappers, blackbirds, thrushes, young pigeons, sparrows, partridges, capons, almonds, pine nuts, raisins, currants, strong wines taken sparingly, especially those made of the grapes of Italy. But erection is chiefly caused by scuraum, eringoes, cresses, crysmon, parsnips, artichokes, turnips, asparagus, candied ginger, acorns bruised to powder and drank in muscadel, scallion, sea shell fish, etc. But these must have time to perform their operation, and must be used for a considerable time, or you will reap but little benefit from them. The act of coition being over, let the woman repose herself on her right side, with her head lying low, and her body declining, that by sleeping in that posture, the cani, on the right side of the matrix, may prove the place of conception; for therein is the greatest generative heat, which is the chief procuring cause of male children, and rarely fails the expectations of those that experience it, especially if they do but keep warm, without much motion, leaning to the right, and drinking a little spirit of saffron and juice of hissop in a glass of Malaga or Alicant, when they lie down and arise, for a week.

For a female child, let the woman lie on her left side, strongly fancying a female in the time of procreation, drinking the decoction of female mercury four days from the first day of purgation; the male mercury having the like operation in case of a male; for this concoction purges the right and left side of the womb, opens the receptacles, and makes way for the seminary of generation. The best time to beget a female is, when the moon is in the wane, in Libra or Aquaries. Advicenne says, that when the menses are spent and the womb cleansed, which is commonly in five or seven days at most, if a man lie with his wife from the first day she is purged to the fifth, she will conceive a male; but from the fifth to the eighth a female; and from the eighth to the twelfth a male again: but after that perhaps neither distinctly, but both in an hermaphrodite. In a word, they that would be happy in the fruits of their labour, must observe to use copulation in due distance of time, not too often nor too seldom, for both are alike hurtful; and to use it immoderately weakens and wastes the spirits and spoils the seed. And this much for the first particular.

The second is to let the reader know how the child is formed in the womb, what accidents it is liable to there, and how nourished and brought forth. There are various opinions concerning this matter; therefore, I shall show what the learned say about it.

Man consists of an egg, which is impregnated in the testicles of the woman, by the more subtle parts of the man's seed; but the forming faculty and virtue in the seed is a divine gift, it being abundantly imbued with vital spirit, which gives sap and form to the embryo, so that all parts and bulk of the body, which is made up in a few months and gradually formed into the likely figure of a man, do consist in, and are adumbrated thereby (most sublimely expressed, Psalm cxxxix.: "I will praise Thee, O Lord, for I am fearfully and wonderfully made.")

Physicians have remarked four different times at which a man is framed and perfected in the womb; the first after coition, being perfectly formed in the week if no flux happens, which sometimes falls out through the slipperiness of the head of the matrix, that slips over like a rosebud that opens suddenly. The second time of forming is assigned when nature makes manifest mutation in the conception, so that all the substance seems congealed, flesh and blood, and happens twelve or fourteen days after copulation. And though this fleshy mass abounds with inflamed blood, yet it remains undistinguishable, without form, and may be called an embryo, and compared to seed sown in the ground, which, through heat and moisture, grows by degrees to a perfect form in plant or grain. The third time assigned to make up this fabric is when the principal parts show themselves plain; as the heart, whence proceed the arteries, the brain, from which the nerves, like small threads, run through the whole body; and the liver, which divides the chyle from the blood, brought to it by the vena porta. The two first are fountains of life, that nourish every part of the body, in framing which the faculty of the womb is bruised, from the conception of the eighth day of the first month. The fourth, and last, about the thirtieth day, the outward parts are seen nicely wrought, distinguished by joints, from which time it is no longer an embryo, but a perfect child.

Most males are perfect by the thirtieth day, but females seldom before the forty-second or forty-fifth day, because the heat of the womb is greater in producing the male than the female. And, for the same reason, a woman going with a male child quickens in three months, but going with a female, rarely under four, at which time its hair and nails come forth, and the child begins to stir, kick and move in the womb, and then the woman is troubled with a loathing for meat and a greedy longing for things contrary to nutriment, as coals, rubbish, chalk, etc., which desire often occasions abortion and miscarriage. Some women have been so extravagant as to long for hob nails, leather, horse-flesh, man's flesh, and other unnatural as well as unwholesome food, for want of which thing they have either miscarried or the child has continued dead in the womb for many days, to the imminent hazard of their lives. But I shall now proceed to show by what means the child is maintained in the womb, and what posture it there remains in.

The learned Hippocrates affirms that the child, as he is placed in the womb, has his hands on his knees, and his head bent to his feet, so that he lies round together, his hands upon his knees and his face between them, so that each eye touches each thumb, and his nose betwixt his knees. And of the same opinion in this matter was Bartholinus. Columbus is of opinion that the figure of the child in the womb is round, the right arm bowed, the fingers under the ear, and about the neck, the head bowed so that the chin touches the breast, the left arm bowed above both breast and face and propped up by the bending of the right elbow; the legs are lifted upwards, the right so much that the thigh touches the belly, the knee the navel, the heel touches the left buttock, and the foot is turned back and covers the secrets; the left thigh touches the belly, and the leg lifted up to the breast.
