which is sufficiently blameable in any, but in Christians, who pretend to tread in their Saviour’s Steps, and to obey all his Commandments, is most exceedingly provoking.’ Though the Sin of Uncleanness be heinous in it self, as appears by what has been said, and is oftentimes attended with a train of Crimes, as Lying, Quarrelling, and others of a flagitious Nature, yet are many Persons so estrang’d to Religion, and even to rational Ethicks, as to be entirely supine and negligent in the suppressing of Impure Cogitations; and on the contrary entertain them with indulgence; so that by degrees, illimitable Passions are establish’d, and the tide of Impurity, at last grows so strong and rapid, that it is not to be repell’d; whence all manner of Evils succeed. Having Theologically discuss’d the several particulars relating to Self-pollution, and other Uncleanness: I come now to my last head, treating of _Generation_, and the sensitive Parts effecting it; but I would by no means have my Reader think, that I examine these particulars with a design to excite Persons to Lewdness, when my Intentions are only to shew the fineness and Beauty of the Parts, whereby will appear how easily they may be violated and impair’d by an unnatural use. [Illustration] _CHAP._ III. _A __DISSERTATION__ upon _Generation_; and of the _Parts_ administring thereunto._ I shall begin with the instruments of _Generation_ in Men. All the parts of _Generation_ merit the Title of noble Parts, as well as the Brain and the Heart; and some Authors give them the preference before the other Parts of the Body, upon this consideration, that they preserve the Species, and the others only keep up the Individuum. The Yard is call’d by Physicians the _Membrum Virile_, because it distinguishes a Man from a Woman: It is plac’d at the lower and external part of the _Abdomen_, and is fasten’d to the _Os Pubis_. This Situation is the more commodious, for that it does not annoy any other part in the time of enjoyment. It has a very peculiar Substance, containing several Vessels, Muscles, Nerves, Arteries, _&c._ Its Skin is finer than that of any other part, to give it a more exquisite sense. It has no Fat; for if it encreas’d in Flesh in proportion with the rest of the Body; it would not only be of too large a size, but become soft, unactive, and insensible; and would cloud the Sense necessary to excite the Passion. The Yard performs its motions by virtue of four Muscles; two for Erection, and two for Ejaculation. These last squeeze the seminal Vesicles, and convey the Seed into the _Urethra_, from whence it sallies out with great force: It is divided into its Body, and two Ends; as for its two extremities one of them is call’d the Glans, or head of the Yard; the other which is fastened to the Belly, is call’d the Root, and is surrounded with Hair, especially upon its upper part, which is call’d the _Pubis_.
