Tiger, Felis Tigris, Linn., which recently died at the Society's Gar- 

 dens, were read. 



The stomach was simple, 18 inches in length, and 13 in its 

 greatest circumference. It was seated in the left hypochondriac 

 and in the umbilical regions. The oesophagus entered it at 3 inches 

 from its cardiac end. Its mucous coat exhibited beautifully minute 

 convoluted p/iftP, perhnps from the arrangement of the gastric glands. 

 The pyloric valve was little distinct. 



The omentum was loaded with fat, and extended about two thirds 

 of the distance to the pubes. 



The duodenum was loosely attached by a broad mesentery, and 

 measured in length about 1 2 inches : the length of the small intes- 

 tines was 18 feet; their circumference was uniform throughout, 

 24- inches. Tlie caecum was 2 inches long, and the same in circum- 

 ference ; its form being that which is met with in the domestic Cat. 

 The length of the large intestines was 2 feet 10 inches ; their circum- 

 ference 4 inclies. The muscular coat of the intestines was thick 

 throughout their whole extent. 



The liver, when spread out, resembled in form a vine-leaf, being di-* 

 vided by deep fissures reacliing nearly to the hepatic vessels. It con- 

 sisted of five lobes, the middle one of which was the largest ; this 

 presented below a deep fissure lodging the gall-bladder, which 

 seemed to perforate the substance of the visciis, its fundus appearing 

 in a hole on the convex surface. The length of the gall-bladder was 

 3 inches ; its circumference 34- ; its shape pyriform ; and its neck 

 convoluted as in the domestic Cat -. the length of the neck, when 

 unravelled, was 2-i inches. The bile entered the intestine at 4 inches 

 from the pylorus, in common with the pancreatic secretion. 



The pancreas was placed between the layers of peritoneum which 

 formed the mesentery of the duodenum. It was of a long ribband- 

 like form ; 22 inches in length ; 1 inch in its greatest and -f^ths 

 in its least breadth. 



The spleen was loosely attached to the cardiac extremity of the 

 stomach ; of a flat, club-shaped form ; and measured at its broadest 

 part 3 inches in width, at its narrowest, 1 inch : its greatest thick- 

 ness was ^ inch. 



Tlie lungs consisted of four lobes on the right and three on the 

 left side. 



The heart, of a pyramidal shape, and measuring 5 inches in length 

 and 4 in breadth, was seated in the middle of the chest upon the ster- 

 num. The medium thickness of the muscular parietes of the right ven- 

 tricle was 4c inch, of the left ventricle, fths. There were no traces 

 of Eustachian valve, or of valve to the coronary vein. The vence cavee 

 were two, one superior and one inferior. The primary branches of the 

 aorta were also two. 



The trachea consisted of forty-five rings, each forming rather more 

 than a semicircle and being completed behind by a membrane which 

 had the appearance of being muscular. It divided inferiorly into 

 three branches, two of which passed to the right, and one to the left 

 lung. The vocal ligaments were little prominent, and the sacculus 

 laryngis was scarcely perceptible.
