the Committee a portion of the notes taken on that occasion, confi- 

 ning myself to such additional circumstances as have not appeared in 

 previous accounts. Of this species the latest anatomical description 

 is that which is given by Mr. Yarrell in the 4th volume of the ' Zoolo- 

 gicalJournal ' to the accuracy of which this dissection bore ample testi- 

 mony. 



" The disposition of the viscera of the abdomen was as follows. The 

 liver occupied the epigastric region and a part of both hypochondria : 

 the stomach lay transversely below the liver : two large transverse 

 folds of the colon stretched across the umbilical region : and iti the 

 lowest part of the abdomen the ccecum alone was visible. These viscera 

 were partially covered by a thin epiploon, in which was very little fat. 



"The oesophagus enters the stomach about one third from the left 

 extremity. The cuticular membrane is continued from it into the 

 stomach, for the extent of l 6 inches towards the left end, and for 

 7 inches towards the pylorus; the rest of the cavity had a smooth 

 or compact villous surface, with a few narrow but well defined rugae; 

 the villous coat became thicker and apparently more glandular towards 

 the pylorus. The pyloric end of the stomach had a tendinous lustre 

 on each side. The colour of the villous coat of the stomach was dif- 

 ferent from that of the duodenum. In this intestine the villous mem- 

 brane was raised in transverse folds or valvule conniventes for the 

 extent of 4 or 5 inches ; but the inner surface of the rest of the 

 small intestines was without any folds. The diameter of the small 

 intestines was 1 inch and a half, their length 45 feet. Near the 

 termination of the ilium there were some small ulcerations. The 

 mesenteric arteries form only a single series of arches in the mesentery 

 close to the intestine. The principal mass of the mesenteric glands 

 was situated at the termination of the ilium, and appeared to be dis- 

 eased, being hard and scirrhous, and containing gritty or calcareous 

 particles. The large intestines commenced by a capacious ccecum of 

 the form described and represented by Mr. Yarrell j after this the 

 colon forms the transverse folds before mentioned, which are connected 

 together; and then becomes free, or has a loose mesocolon; and it is 

 here that the faces appear to be first formed or separated. 



"The liver consists of four lobes, the two external being connected 

 by a transverse band passing along the under surface of the liver. The 

 largest lobe, the third from the right, had two deep notches, into the 

 left of which the coronary ligament and remains of the umbilical chord 

 passed. The gall-bladder is deficient, and the gall-duct emerges from 

 the transverse connecting band mentioned above ; it is about 2 lines 

 in diameter, and terminates in the duodenum '6 inches from the pylo~ 

 rus. From this point it was traced backwards for 7 inches without 

 varying its diameter. The pancreas extended from the spleen to the 

 duodenum, and measured 9 inches in length j at the duodenum a pro- 

 cess descended at a right angle in the process of the peritoneum con- 

 necting the duodenum to the ccecum, which process measured 5 inches 

 in length. The spleen is a flattened elongated body, measuring in 

 length 1 foot 8 inches, and in breadth 4 inches. 



" The kidneys were conglobate, 6 inches long, 3| inches broad :
