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 cesophagus entered it at 3 inches 

 from its cardiac end. Its mucous coat exhibited beautifully minute 

 convolutedp/ifiiF, peihiips from the arrangement of the gastricglands. 

 The pyloiic 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 12 inches: the length of the small intes- 

 tines was 18 feet; Iheir circumference was uniform throughout, 

 2-i- inches. Tiie cacum was 2 inches long, and the šame in circum- 

 ference J its form being that vvhich is met vvith in the domestic Cat. 

 The length of the large intestines vvas 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 reaching nearly to the hepatic vessels. It con- 

 sisted of five lobes, the middle one of wbich vvas the largest ; this 

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

 seemed to perforate the substance of the viscus, its futidus appearing 

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

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

 convoluted as in the domestic Cat : the length of the neck, when 

 unravelled, vvas 2-į- inches. The bile entered the intestine at 4 inches 

 from the pyloms, in common vvith the pancreatic secretion. 



The pancreas vvas placed betvveen the layers of peritoneum vvhich 

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

 like form ; 22 inches in length j 1 inch in its greatest and -Iths 

 in its least breadth. 



The spleen vvas loosely attached to the cardiac extremity of the 

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

 part 3 inches in vvidth, at its narrovvest, 1 inch : its greatest thick- 

 ness vvas ^ inch. 



The 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, vvas seated in the middle of the chest upon the ster- 

 num. Themedium thickness of the muscidar parietės of the right ven- 

 tricle was ^ inch, of the left ventricle, |ths. There vvere no traces 

 of Eustachian valve, or of valve to the coronary vein. The vertce cav<e 

 vvere tvvo, one superior and one inferior. The primary branches of the 

 aorta vvere also tvvo. 



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

 than a semicircle and being completed behind by a membrane vvhich 

 had the appearance of being muscular. It divided inferiorly into 

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

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

 laryngis was scarcely perceptible.
