17-i ABNORMAL FEATURES IN THE PERITONEUM OF A RACCOON. 



(text-fig. 18, no. 15) by a peritoneal sheet (text-fig. 18, no. 16), 

 and to the posterior parietal peritoneum. On the surface of the 

 bare area (text-fig. 18, no. 30), the left ovarian vessels cross the 

 kidney (text-fig. 18, no. 31), and pierce the capsule on its outer 

 border to reach the ovary. 



Omental Adhesions. 



The great omentum filled the abdominal cavity, but it has been 

 shortened for descriptive purposes in text-fig. 18. When it was 

 gently raised, it was seen that delicate filiform bands connected 

 it to the abdominal viscera. These are indicated by Roman 

 numerals in text-fig. 18. Bands 1 and 2 were tight, but all the 

 others were loose. 



The band number 1 ran from the front of the great omentum 

 across the front of the stomach to the anterior surface of the 

 small omentum. Bands 2 and 7 ran from the free edge of 

 the omentum to the inner surface of the liver and the outer 

 border of the spleen respectively. Bands 3 and 6 ran from the 

 under surface of the great omentum ; the former ended in the 

 mesentery of the duodenum, and the latter on the left extremity 

 of the pancreas. Bands 4 and 5 gradually opened out on the 

 free edge of the great omentum ; the former terminated in 

 the mesentery of the ileum, and the latter on a nodule on the 

 apex of the urinary bladder (text-fig. 18, no. 17). On each side 

 of the bladder-wall a tortuous ridge, containing an artery, ran 

 down from the afore-mentioned nodule. 



These bands are probably the result of inflammation. 



Duodenal Bands. 



The outer surface of the duodenum is attached by bands to the 

 parietal peritoneum (text-fig. 18, no. 22), and the mesentery of 

 the descending colon (text-fig. 18, no. 20). Between the bands 

 and the duodenal mesentery is a pocket (text-fig. 18, no. 9).
