    The two bodies of the uteri lie with their mesial surfaces in close apposition, surrounded by a common peritoneal layer, except anteriorly, where they are separate over a short part of their extent and connected by the common median portion of the lifiamenta lata (the ligamentum uterorum superius of Brass). The “ bodies ” alone of the uteri are visible when, after pulling aside the vaginal caeca, the organs are examined from the ventral aspect. They lie dorsal to the posterior portions of the vaginal caeca and are connected posteriorly with the latter by a low median peritoneal fold. Viewed from the dorsal aspect (Plate i., fig. 1) the uteri are seen throughout their extent. In fig. 1 it will be noticed that the groove betw^een the bodies of the uteri fades aw'ay at the commencement of the contracted necks which. except for a faint median line, appear to form externally a single I . tube about half the thickness of one of the uteri. The cavities ^ of the uterine necks are separated from each other posteriorly by a common partition w'all and each opens into a very short median vaginal cul-de-sac. The two cul de-sacs, also separated by a common partition wall, externally appear to form the direct con- tinuation of the uterine necks and are not in any way outwardly marked off from the latter. They form the extreme posterior end of the portion marked ut.n. in fig. 1. While the bodies of the uteri are only connected with the vaginal ca?ca by a low median fold, the uterine necks become closely united over their entire breadth with the dorsal surface of the latter. Posteriorly, how- ever, the c£eca rapidly decrease in size to pass directly over into the lateral vaginal canals, while the latter at the same time take a very slight outward bend, with the result that in this region the hinder sections of the uterine necks, together with the median vaginal cul-de-sacs, come to lie imbedded in the connective tissue enclosed between the upper ends of the lateral vaginal canals. r (X About on a level with the union of the uterine necks with the dorsal surface of the cjeca, the fundus of the bladder likewise becomes united with their ventral surface so that all three parts are here united into a single mass (Plate ii., fig. 3, var/.c., hi.). 4
