NATURAL HISTORY.

than is usually observed in othef 

 quadrupeds. 



The viscera of the abdomen ex- 

 hibited marks of the inflammation 

 I have mentioned. The stomachs 

 were distended with gns, and the 

 mucous membrane inflamed. The 

 ejjideniiis of the ruminating sto- 

 mach had already peeled oif, and 

 the intestines were nearly in the 

 Same state. There was no urine 

 in the bladder. The epiploons 

 exhibited nothm<j but very thin 

 membranous skins destitute of fat. 



The di>tribution and figure of 

 the stomachs were the same as 

 in the camel. The second was full 

 of vesicles, from which a serous 

 or aqueous fluid issued abundant- 

 ly. The paunch and the other two 

 stomachs did not differ in the in- 

 terior form of their cavities from 

 those of the camel. Tlie cellular 

 stomach was remarkable for the 

 internal arranjjement of the cells ; 

 they having apertures of communi- 

 cation furnished with membranous 

 valves, which no doubt may still 

 be discovered in the dried sto- 

 mach of the animal. The last 

 stomach is united to a portion of 

 intestine, which maybe considered 

 as the duodenum. This was con- 

 tinued in another intestine of equal 

 bulk, which, after forming an 

 arch in the circumference of the 

 abdomen, terminated in the left 

 lumbar region in a cul-de-sac ; 

 whence issued another intestinal 

 tube, very slender and smooth, 

 and forming ten or twelve concen- 

 tric circles in the space made by 

 the former. The circumvolutions 

 were attached to a common me- 

 sentery. This slender intestine af- 

 terward made a thousand circum- 

 Tolutions in the ahdomen, termi- 

 nating at length in another caecum 



without an appendage like the 

 former; whence issued a portion 

 of intestine of considerable hulk, 

 which, after forming two or three 

 curves in the manner of a colon, 

 terminated in the rectum. 



Thus it appe .rs, that the vicuna 

 has three sets of intestines, the first 

 and third large, and the middle 

 slender. 



] met with no worms in the in- 

 testines, the infinite windings and 

 intersections of which would ap- 

 pear favoiirahle to their formation. 



The liver, which I did not at 

 first perceive, was found deeply 

 concealed behind the stomach, and 

 attached by very clo>e membranous 

 ligaments to the crura of the dia- 

 phragm, and to the corresponding 

 dorsal vertebrce. It was of very 

 small bulk, of an oval figure, flat- 

 tened transversely, and exhibiting 

 two lobules at its anterior edge. It 

 was destitute of a gall bladder j 

 and the bile was taken diiectly 

 from the liver by a duct, that con- 

 veyed it into a portion of the duo- 

 denum. This duct and the vena 

 portae crossed each other. 



The spleen, which was likewise 

 very small, and of a rounded form, 

 was situate in the left lumi)ar re- 

 gion, contiguous to the kidney of 

 the same side. These two organs 

 were inclosed in one common du-» 

 plicature of the peritoneum. 



The lungs exhibited nothing re* 

 markable. They partook of the 

 general inflammation, and the 

 bronchiae were filled with a frothy 

 sanguineous fluid. The tiacheaand 

 larynx had the same figure and or-» 

 ganization as those of the camel. 



The heart, which was of a size 

 proportional to the animal, formed 

 almost a perfect cone; only its 

 point, which was very acute, curr-
