    A CONTRIBUTION TO THE MORPHOLOGY OF THE HUMAN URINOGENITAL TRACT. By D. Berry Hart, M.D., F.R.C.P. Edin., etc., Lecturer on Midwifery and Diseases of Women, School of the Eoyal Colleges, Edin- burgh, etc. (Plates XXXV, XXXVI.) In two previous communications I discussed the questions of the origin of the hymen and vagina. I there attempted to show that the lower ends of the Wolffian ducts enter into the formation of the former, and that the latter was Mullerian in origin only in its upper two-thirds, the lower third being formed by blended urinogenital sinus and Wolffian ducts. In following this line of inquiry more deeply it resolved itself into a much wider question—viz, the morphology of the human urinogenital tract, and this has occupied much of my spare time for the last five years. It soon became evident that what one required to investigate was really the early history and ultimate fate of the Wolffian body and its duct, as well as that of the Mullerian duct, and this led one back to the fundamental facts of de- velopment in relation to bladder and bowel. The result of this investigation will therefore be considered under the following heads :— I. The Development of the Urinogenital Organs, Rectum and External Genitals in the Human Fcetus up to the end of the first Month. The Development of the Permanent Kidney is not CONSIDERED. II. The Condition of these Organs at the 6th to 7th Week. III. The Changes at the 14th Week and at the 24th. IV. The Structure and Origin of the Adult Human Vagina. V, The Genital Tract in the Marsupialia. VI. The Analogues of the Human Male and Female Genital Tract.
