wall of the abdomen at the anterior border of the pancreas, thus 

 forming the transverse meso-colon. On reaching the anterior 

 border of the pancreas the two layers of the transverse meso-colon 

 take leave of each other, and form an ascending and a descend- 

 ing layer. The ascending layer passes upwards over the anterior 

 surface of the pancreas, the second part of the duodenum, and 

 the posterior portion of the under surface of the diaphragm.

from which it passes to the postero-inferior border of the liver, 

 thus forming the inferior layer of the coronary ligament. Having 

 covered Spigel's lobe, it arrives at the posterior li]> of the portal 

 fissure, where it is continuous with the posterior layer of the gastro- 

 hepatic omentum. 



The descending layer of the transverse meso-colon passes at first 

 backwards upon the inferioi surface of the pancreas, and then 

 downwards over the third part of the duodenum, at the lower 

 border of which it is conducted off to the jejunum and ileum by the
