And between the two great _Labia_, appear the four Caruncles call’d _Myrtiformes_ from the resemblance they bear to _Mirtle-berries_. They are small fleshy Eminences surrounding the small Slit, made of the fleshy Wrinkles of the _Vagina_, which render the Passage so much the straighter. Their use is to heighten the mutual pleasure of Enjoyment, by clinging round and locking up the Yard; and to facilitate the egress of the Child by extension. They are reddish firm and high in Virgins, and join’d sideways to one another by small Membranes, which tie them together, and make them resemble a Rose-bud half blown: But in other Women they are separated by the entry of the Yard. The uniting of the Membranes of the _Carunculæ Myrtiformes_, straighten the Passage, and afford the true mark of _Virginity_, (if there be any such.) The pain of the first Adventure is owing to the forcing of the Passage through, and tearing off those small Membranes; and a Mans Inclinations being always heighten’d in the first Nights Enjoyment, the pain to the Female is encreas’d by his ardent struggles; her Virgin Sufferings augmenting with his affection: But in some Females the _Caruncles_ are rang’d in such a manner, that the Yard may enter without violence, so that there is no certain Evidence of a Maiden-head. Some _Anatomists_ mention a Membrane call’d _Hymen_, seated near the _Caruncles_ in the _Vagina_, which continues stretched over the Passage, ‘till the approach of a Man rends it; and that this _Hymen_ is a mark of _Virginity_; but this is more imaginary than proceeding from any Demonstration. The _Vagina_ is the neck of the Womb, a round Passage between the outer and inner Orifice, which receives the Yard like a Sheath. In Women that never bore Children, this Neck is about four Inches long, and an Inch and a half broad, but after Child-bearing, its capacity cannot be limited. It is nervous, and somewhat spungy, consisting of two Membranes; the Wrinkles of its inner Membrane empower it to prolong, dilate or contract, in order to fit the Yard, of any length or size, and to afford a Passage to the _Fœtus_. The Body and Neck of the Womb, make the Figure of a Bottle turn’d upside down, or rather a proud Flask.
