of the latter passage. In the luniiaii subject it is sometimes found in the form of 

 a small muscular cord, or e})ithelial canal, near the cervix uteri or ui)i)er part ai the 

 vagina. According to some anatomists, its lower end is occasionally found as a 

 little tube opening into the side of the vulva near the urinary meatus, but it is 

 doubtful -whether the tube in question is more than a mucous duct, (c) The par- 

 ovarium, or paroophoron, a few scattered, imperfectly devehjjted tub\iles in the 

 neiglil)ourhood of the epoophoron, also representing traces of the \\'olfIian body. 

 They are usually seen as small wliitisli or yellowish grains in the infant, but are 

 rarely demonstrable in the adult. (//) The hydatid of Morgagni, a long iK'dicu- 

 lated vesicle of the size of a millet seed or pea, occasionally dcjiendent from the 

 fimbriae of the tuV)es, is believed to be a relic of the Wolfhan body, (e) Small 

 pedunculated cysts often found on the posterior layer of the broad ligament and 

 derived from the parovarium. (5) The uterine, ovarian, and funicular vessels, 

 anastomosing near the angle of the uterus; and the uterine plexus of nerves. (6j

A (juantity of loose adipose cellular tissue lying between the muscular and other 

 structures and the serous meml»rane, and in continuity with the subperitoneal 

 fascia of the pelvis. (7) Involuntary muscular fibres passing from the obturator 

 fascia to become attached to the sides of the uterus and vagina, en.sheatliing the 

 ves.sels and serving as a sup]jort to the uterus. They may be com])ared with the 

 fibro-muscular subperitoneal bands sui)porting the third stage of the duodenum, 

 the transverse colon and small intestines, and are essentially sustentacular in rela- 

 tion to the viscera and to their vessels and nerves. 



The posterior peritoneal or recto-uterine ligaments are two serous folds 

 which run I)a(kwards from the intraperitoneal iH.itioii of the cervix wXvx'x and vagina 

 to become continuous with the ])eritoneal investment of the secon<l stage of the 

 rectum. They form the lateral l)oundaries of the ])oueh of Douglas, and between 

 their layers lie muscular utero-sacral ligaments, comparalde t<t the expansion in 

 the broad ligaments, with l<>..se connective ti.->ue and a number of anastomosing 

 branches of the uterine and lueninrrlioidal vessels.
