der and onto the upper surface ; thence it passes laterally to 

 the pelvic walls, and from the apex (surrounding the urachus) 

 to the abdominal wall, forming the false ligaments of the blad- 

 der. In the female these folds (of Douglas) pass from the rec- 

 tum to the uterus, enclosing the utero-sacral ligaments and 

 forming the pouch of Douglas between them ; thence the peri- 

 toneum runs over the back and fundus of the uterus, passes 

 in two folds, between which is the utero-vesical pouch, to the 

 bladder, and continues as in the male; from each side of the 

 uterus it runs to the pelvic wall in a wide fold (broad liga- 

 ment). [1100] 



Traced transversely, just above the iliac crest, after leaving 

 the anterior abdominal wall it runs on each side to the back, 

 and thence inward over the colon and across the Psoas, ureters, 

 and great vessels ; thence it runs forward around the small in- 

 testine and back again (mesentery) . Higher up, to the left, it 

 runs on the posterior wall behind the stomach and spleen to 

 the left kidney, covers the upper and outer part of this, and 

 runs forward (posterior layer of lieno-renal ligament) to the 

 spleen. Thence it runs around the spleen to the hilus and then 

 passes (anterior layer of gastro-splenic omentum) to the stom- 

 ach. [1101] 



Small Sac. This diverticulum begins in a narrow passage 

 (foramen of Winslow) just behind and below the portal fissure. 

 In front of the foramen is the free right border of the lesser 

 omentum, containing the portal vein, hepatic artery, and bile 

 duct ; behind it is the vena cava ; below it are the hepatic artery 

 and duodenum; and above it is the caudate lobe. [1102] 



The posterior layer runs, from the foramen, over the vena 

 cava and upward to form a cul-de-sac behind the Spigelian 

 lobe. To the left it runs over the pancreas, left kidney, and 

 suprarenal, passes thence (anterior layer of lieno-renal liga- 

 ment) to the spleen, where it covers the inner part of the gas- 

 tric surface, and then runs (posterior layer of gastro-splenic 

 omentum) to the stomach. From the anterior border of the
