El âddad (the biter) - The vulva which, when the member has got into it and is burning with passion, opens and shuts again upon the same fiercely. It is chiefly when the ejaculation is coming that the man feels the head of his member bitten by the mouth of the matrix. And certainly there is an attractive power in the same when it clings, yearning for sperm, to the gland, and draws it in as far as it can. If God in his power has decreed that the woman shall become pregnant the sperm gets concentrated in the matrix, where it is gradually vivified; but if, on the contrary, God does not permit the conception, the matrix expels the seed, which then runs over the vagina.

El meusass (the sucker) - This is a vagina which in its amorous heat in consequence of voluptuous toyings, or of long abstinence, begins to suck the member which has entered it so forcibly as to deprive it of all its sperm, dealing with it as a child drawing on the breast of the mother.

The poets have described it in the following verse:

She - the woman shows in turning up her robe
An object - the vulva - developed full and round,
In semblance like a cup turned upside down.
In placing thereupon your hand, you seem to feel
A well-formed bosom, springy, firm, and full.
In boring in your lance it gets well bitten,
And drawn in by a suction, as the breast is by a child.
And after having finished, if you wish to recommence,
You'll find it flaming hot as any furnace.

Like to a man extended on his chest, she - the vulva - fills the hand
Which has to be well stretched to cover it.
The place it occupies is standing forth
Like an unopened bud of the blossom of a plum tree.
Assuredly the smoothness of its skin
Is like the beardless cheek of adolescence;
Its conduit is but narrow,
The entrance to it is not easy,
And he who essays to get in
Feels as though he was butting against a coat of mail.
And at the introduction it emits a sound
Like to the tearing of a woven stuff.
The member having filled its cavity,
Receives the lively welcome of a bite,
Such as the nipple of the nurse receives
When placed between the nursling's lips for suction.
Its lips are burning,
Like a fire that is lighted,
And how sweet it is, this fire!
How delicious for me.

El harr (the hot one) - This is one of the most praiseworthy vulvas. Warmth is in fact very much esteemed in a vulva, and it may be said that the intensity of the enjoyment afforded by it is in proportion to the heat it develops.

Poets have praised it in the following verses:

The vulva possesses an intrinsic heat;
Shut in a solid heart (interior) and pent up breast (matrix).
Its fire communicates itself to him that enters it;
It equals in intensity the fire of love.
She is as tight as a well- fitting shoe,
Smaller than the circle of the apple of the eye.

More names might certainly be found applicable to the sexual organs of woman, but the number of those mentioned above appears to me ample. The principal object of this work is to collect together all the remarkable and attractive matters concerning coitus, so that he who is in trouble may find consolation in it, and the man to whom erection offers difficulties may be able to look into it for a remedy against his weakness. Wise physicians have written that people whose members have lost their strength, and are afflicted with impotence, should assiduously read books treating of coition, and study carefully the different kind of lovemaking, in order to recover their former vigour. A certain means of provoking erection is to look at animals in the act of coition. As it is not always everywhere possible to see animals whilst
