The orificium vagina differsgreatly, both as to size and ap-pearance, in virgins, in womenaccustomed to sexual intercourse,and in those who have bornechildren. In virgins (vide Fig. 1) the an-terior extremity of the vagina ter-minates in a thin membrane, termed the hymen, which projects betweenthe labia minora.
