passes on to its posterior wall. At this point its description was commenced. 

 The general relations of the greater and the lesser sac are also evident in fig. 905 

 showing the lines along which the parietal peritoneum is reflected from the pos- 

 terior abdominal wall as the visceral peritoneum, forming the various mesenteries 

 and covering the various abdominal organs.

The precise manner in which certain organs — such as the liver, the csecum, the duodenum, 

 and the kidneys — are invested by peritoneum is described in the accounts of those viscera. 

 To such accounts the reader is referred for a description of the many 'ligaments' (such as 

 those of the bladder and liver) which are formed by the peritoneum. 



The great omentum. — As is evident from its development, the great omentum 

 [omentum majus] is formed of four layers of peritoneum, though this is quite 

 impossible to demonstrate in an adult, the individual layers having become 

 adherent. 



The great omentum acts as an apron, protecting the intestines and providing
