reality there cannot be the slightest doubt about the function of the nymphæ, as, in Hyrtl's phrase, "the naiads of the urinary source," and it can be demonstrated by the simplest experiment.[94] The nymphæ form the intermediate portal of the vagina, as the canal which conducts to the womb was in anatomy first termed (according to Hyrtl) by De Graaf.[95] It is a secreting, erectile, more or less sensitive canal lined by what is usually considered mucous membrane, though some have regarded it as integument of the same character as that of the external genitals; it certainly resembles such integument more than, for instance, the mucous membrane of the rectum. In the woman who has never had sexual intercourse and has been subjected to no manipulations or accidents affecting this region, the vagina is closed by a last and final gate of delicate membrane--scarcely admitting more than a slender finger--called the hymen. The poets called the hymen "fios virginitatis," the flower of virginity, whence the medico-legal term _defloratio_. Notwithstanding the great significance which has long been attached to the phenomena connected with it, the hymen was not accurately known until Vesalius, Fallopius, and Spigelius described and named it. It was, however, recognized by the Arab authors, Avicenna and Averroes. The early literature concerning it is summarized by Schurig, _Muliebria_, 1729, Section II, cap. V. The same author's _Parthenologia_ is devoted to the various ancient problems connected with the question of virginity. To say that this delicate piece of membrane is from the non-physical point of view a more important structure than any other part of the body is to convey but a feeble idea of the immense importance of the hymen in the eyes of the men of many past ages and even of our own times and among our own people.[96] For the uses of the feminine body, or for its beauty, there is no part which is more absolutely insignificant. But in human estimation it has acquired a spiritual value which has made it far more than a part of the body. It has taken the place of the soul, that whose presence gives all her worth and dignity, even her name, to the unmarried woman, her purity, her sexual desirability, her market value. Without it--though in all physical and mental respects she might remain the same person--she has sometimes been a mark for contempt, a worthless outcast.[97] So fragile a membrane scarcely possesses the reliability which should be possessed by a structure whose presence or absence has often meant so much. Its absence by no means necessarily signifies that a woman has had intercourse with a man. Its presence by no means signifies that she has never had such intercourse.
