to be continued on the concave curvature of the duodenum as far as the 

 caecum. By its posterior border, the great omeiitum is spread around the 

 termination of the largo colon and the origin of the floating colon, where it is 

 confounded with the visceral peritoneum of these organs, as well as \vith the 

 parietal peritoneum. It results from this arrangement that the great omentum 

 forms behind the stomach, and in front of the adherent portion of the large 

 colon, a space that communicates with the great peritoneal cavity by a very 

 narrow opening, the foramen of Winslow. This aperture is included between 

 the vena port, posterior vena cava, anterior extremity of the pancreas, and 

 the lesser curvature of the stomach. To the left of the latter viscus, on the 

 external face of the great omentum, the spleen is suspended ; consequently, 

 that portion extending from the spleen to the ventriculus is named the 

 gastro-splenic omentum. 



The two layers composing the great omentum arc very thin for the 

 greater part of their extent, and include the blood vessels between them. 

 In emaciated animals these vessels are distinctly seen, owing to the trans- 

 parency of the membranes, and they give the omentum a lace-work appear- 

 ance; but in fat subjects they are concealed by the adipose tissue deposited 

 along their course, and which may accumulate in considerable quantity. 



In the sublumbar region, the parietal peritoneum forms several folds ; 

 these are : the hepatico-renal ligament, extending from the right lobe of the 

 liver to the anterior border of the right kidney; the Tujanu-nt <>/ tin- A//^/.s 

 SpigtJit, the mesentery proper, the colic mesentery ; lastly, the greatly de- 

 veloped lamina) surrounding the caecum and the second flexure of the colon, 

 which constitute the meso-ctecum and meso-colon.
