there were large glandulas maxillares. The tongue was a little above 3 inches 

 long, about -I inch broad ; it was rough, having several protuberances, whose 

 points looked inwards. The voice or noise it made, was a little growling. 



The abdomen or belly was divided from the tliorax, by a large, strong, fleshy 

 diaphragm; for the thorax near the throat was small, then gradually as it de- 

 scends it enlarges its capacity ; so that here, where the diaphragm was fastened, 

 its compass was very large ; which might be rendered the more so, because the 

 animal often hangs by its tail, by which the viscera in the abdomen must press 

 upon it. But that they might not too much, we shall see what provision na- 

 ture has made for it, by her great contrivance in suspending the intestines. 

 The ventricle or stomach somewhat resembled the usual make, inclining to that 

 of a half moon ; but the two orifices of the gula, and the pylorus, were both 

 placed so near each other, that they seemed to touch or meet ; and when the 

 stomach was opened, there was only a very slender isthmus, or wall, that parted 

 them. These orifices were not at the extremities of the stomach, as usual, but 

 inserted almost in the middle of the upper part, but more inclining towards 

 that which respects the duodenum. The stomach appeared but small, being 

 much contracted, for it had not eaten any thing for some days ; it measured 

 about 3i- inches in length, and about 2 inches in depth : the gula, which con- 

 veys the food into the stomach, consisted of strong muscular fibres, and was 

 about 9 inches in length: the pylorus, that carries out, seemed to have its 

 passage free and open, without that annular constriction of valve, as in most 

 other animals ; though here was observed a larger body of muscular fibres than 

 in the other intestines. 



I observed at one side a perforation or hole through, and round, about the 

 size of a pea. That it was occasioned by an ulcer there, I plainly perceived by 

 the lips or edges, which were not fresh, but had an ulcerated matter about 

 them ; and this was doubtless the occasion of the animal's death; for it had 

 fallen from its food, and had pined away for some time before, and by its uneasy 

 motion, made its keeper suspect it had swallowed something that stuck in its 

 throat, or injured its stomach. A like accident as this (a perforation of the 

 stomach) I have three times met with in dissecting human bodies. What ap- 

 pears to me most likely to be the cause of this perforation, is, that some of the 

 glands in the >tomach, such as Peyerus (De Glandulis Intestin.) and Dr. Grew 

 (Comparative Anatomy of Stomachs and Guts) describe in the intestines, being 

 become scrophulous or steatomatous, might imposthumate, and so corrode the 

 coats of the stomach, and cause a perforation. And I am the rather of tiiis opi- 

 nion, because in those instances I mentioned of human bodies, I found in other 

 places of the stomach these glands very large and steatomatous; though
