now, in anticipation of the references to peritoneal relations which necessarily follow 

 in the consideration of the organs, to point out that the parietal and visceral portions 

 of the serous membrane are continuous, the former investing the abdominal walls, 

 the latter the organs. The .peritoneal folds passing from a viscus to the body-wall 

 have received in many cases the name li^ameyits, although often such bands con- 

 tribute little support. The intestinal canal was originally attached to the abdominal 

 wall by a fold covering vessels and nerves named the mesentery, parts of which per-

sist as free folds, while others fuse with the abdominal walls. The term mesentery is 

 vaguely applied to that portion going to the jejuno-ileum, while other parts are distin- 

 guished by the name of the part of the intestine to which they are attached, as meso- 

 colon. The term omentimi is applied to folds attached to the stomach, as the gastro- 

 hepatic omeiitum. The peritoneal sac is entirely closed, except in the female at the 

 upper end of the oviduct, where the mucous membrane of the tube and the serous 

 lining are directly continuous. The opposed smooth walls of the peritoneal sac are
