Two mucous sacculi, about 1 inch in diameter and 1^ inch in depth, 

 are produced from the upper and back part of the pharynx into the 

 pterygoid fossae, on each side the basisphenoid. Between the mouths 

 of these saccuh there projects from the back part of the pharynx a 

 glandular prominence or caruncle, about 7 lines long by 5 lines broad. 

 At the lower and back part of the pharynx a third median sacculus 

 is developed, just below the ' constrictores pharyngis^ ; in this re- 

 markable structure the Wart-Hog resembles the Babyrussa*. The 

 oesophagus commences between this sacculus behind and two large 

 post-arytenoid sacculi in front, and is divided from both by a trans- 

 verse membranous ridge or wall. The long ligamentous crura of the 

 epiglottis are continued from the sides and back part of the post- 

 arytenoid sacculi to that cartilage, which is unusually distant from 

 the larynx. The convex border of the broad epiglottis projects into 

 the posterior nostril. The oesophagus descends behind the trachea to 

 the thorax, and in the posterior mediastinum it is suspended by a fold 

 of the pleura, about 1^ inch broad, which attaches the tube to the 

 descending aorta, after it has passed through the arch. 



The stomach is of small size and simple shape ; its length in a 

 straight line is 9 inches ; following its greater curvature 1 foot 

 7 inches ; the lesser curvature, or the distance from tbe cardia to the 

 pylorus, being only 3 inches. The left end extends about '6]; inches 

 beyond the cardia, and the right end projects about 2 inches to the 

 right of the pylorus. It presents the usual form of the simple sto- ' 

 raach, but the cardiac blind end is marked off by a slight constric- 

 tion, hardly, however, to the same degree as in the Common Hog ; 

 and far from presenting the complexity of the stomach in the Baby- 

 russa. The great omentum is continued from behind the great cur- 

 vature, and was folded or crumpled up behind and beneath the sto- 

 mach, enclosing the spleen, which was to the left and a little behind 

 the great end of the stomach. No part of the omentum was visible 

 when the abdominal cavity was exposed, and but little of the stomach 

 could be seen. Almost the only viscera that presented themselves 

 were the large spiral coils of the colon, closely united together by 

 mesocolic bands laden with fat, about an inch in breadth. The 

 caecum was in the left lumbar region. The stomach extended from 

 the left hypochondrium across the epigastric to the right hypochon- 

 driac regions. The liA^er extended from the right hypochondrium to 

 the left, but did not cover all the great end of the stomach. The 

 small intestines lay concealed behind the colon. 



The oesophagus, which is 2 inches in circumference at its termi- 

 nation in the stomach, opens nearer the posterior than the ante- 

 rior surface of the lesser curvature, 3^ inches from the left end, 

 which forms a prominence above the concavity leading to it from the 

 gullet. 



The oesophageal epithelium is continued a little way on the inner 

 surface of the stomach, forming a thin, narrow, oval patch, extend- 

 ing \\ inch to the left of the cardia, frds of an inch to the right and
