limbs of the sheet play important parts in the formation of 

 the mesentery and the ligamentum hepato-cavo-duodenale of 

 Klaatsch. 



The right limb is inserted into the floor of a groove. It passes 

 round the right border of the liver and separates into two layers 

 which pass along the sides of the vena cava inferior. One-half 

 covers the right abdominal wall, and the other covers the dorsal 

 abdominal Avail and can be traced into the common mesentery 

 (text-fig. 13, Gd and T>d). 



In the angle between the two limbs the vena cava inferior, 

 arched over by peritoneum, can be seen (text-fig. 13, A, a) running 

 to the diaphragm.

The common mesentery viewed from the right (A) and left (B). Lig. Sus., suspen- 

 sory ligament; C.B.D., common bile-duct; Pa., pancreas : Sp., spleen; Pi/., 

 the dorsal and ventral limbs and flexure of the pylorus ; the unmarked dotted 

 line is the line of fusion of the great omentum and mesentery. 



The left limb of the sheet is the true suspensory ligament. It 

 passes into the fissure between the left and right lobes of the 

 liver. It turns round the left hepatic margin, and is attached to 

 the posterior surface from the left border to the origin of the 

 common bile-duct. The lesser omentum fuses with it. It is con- 

 tinued as the common mesentery, and is combined therein with 

 part of the ligamentum hepato-cavo-duodenale. Between the
