On the subject of the ovum the following works may be mentioned : 

 Martin Barry's Researches on Embryology, in Phil. Trans., 1838 and 1839 ; 

 Allen Thomson, Article "Ovum," in Cyclop, of Anat. and Phys. , where 

 also the literature will be found referred to ; Farre, " Uterus and Ap- 

 pendages," in the same ; Pniiger, Die Eierstocke der Saugethiere und des 

 Menschen, Leipzig, 1863; Schron, in Zeitsch. f. Wissenscb. Zoologie, vol. 

 xji. p. 409 ; Grohe, in Virchow's Archiv, vol. xxvi. p. 271 ; also in 

 Virchow's Archiv, vol. xxix. p. 450 ; Spiegelberg, in Virchow's Archiv,

The Fallopian tubes. These tubes, which may be considered as ducts 

 of the ovaries, or oviducts, and which serve to convey the ovum from 

 thence into the uterus, are inclosed in the free margin of the broad liga- 

 ments. They are between three and four inches in length. Their inner 

 or attached extremities, which proceed from the upper angles of the uterus, 

 are narrow and cord-like ; but they soon begin to enlarge, and pro- 

 ceeding outwards, one on each side, pursue an undulatory course, and at 

 length, having become gradually wider, they bend backwards and down- 

 wards towards the ovary, about an inch beyond which they terminate in 

 an expanded extremity, the margin of which is divided deeply into a 

 number of irregular processes named fimbrice ; one of these, somewhat 

 longer than the rest, is attached to the outer end of the corresponding 

 ovary. The wide and fringed end of the Fallopian tube, or rather trumpet, 

 as the term "tuba"' literally signifies, is turned downwards and towards 

 the ovary, and is named the fimbriated extremity (morsus diaboli). In 

 the midst of these fimbrise, which are arranged in a circle, the tube itself 

 opens by a round constricted orifice, ostium abdominale, placed at the

The uterus and upper part of the vagina have been laid open by removing the posterior 

 wall ; the Fallopian tube, round ligament, and ovarian ligament have been cut short and 

 the broad ligament removed on the left side ; u, the upper part of the uterus ; c, the 

 cervix opposite the os internum ; the triangular shape of the uterine cavity is shown and 

 the dilatation of the cervical cavity with the rugae termed arbor vitse ; v, upper part of the 

 vagina ; od, Fallopian tube or oviduct ; the narrow communication of its cavity with 

 that of the cornu of the uterus on each side is seen ; I, round ligament ; lo, ligament of 

 the ovary ; o, ovary ; i, wide outer part of the right Fallopian tube ; f i, its fimbriated 

 extremity ; po, parovarium ; h, one of tlie bydaiids frequently found connected with the 

 broad ligament.
