probably be to supply the part both of epiploon and mesentery in other animals, 

 as to lubricating the intestines. 



There were two distinct ventricles, contrary to the observation of the Royal 

 Academy at Paris The first, and in its natural situation the lower, was con- 

 siderably larger than the 2d, and uppermost muscular one ; besides, that it had 

 strong muscular fibres, both circular and longitudinal: the duodenum comes 

 immediately out of the ^d ventricle. 



Both ventricles were distended beyond their usual form, and filled up with so 

 large a quantity of food of different kinds, as stones, bones, sticks, grain, and 

 other food, that it was almost impossible for them to perform their ofiice of 

 digestion, which very likely was one of the chief causes of the animal's sick- 

 ness and death ; and indeed the contents of both seemed to have undergone 

 but little or no alteration. The epiploon partly covered the first ventricle, but 

 it was no ways proportionable to the size of the animal. 



The spleen was fastened, by a membrane, to the right side of the second 

 ventricle, and was very small, considering the size of the animal. 



The glands of the mesentery were hardly visible, but the veins and arteries 

 very conspicuous. 



The cascums were near 3 feet in length, the diameter 1 inch 8 lines; they 

 were fastened to the ileum, and not to the colon, as the gentlemen of the 

 Royal Academy assert. 



To their description of the kidneys there is nothing to add, except that the 

 two ureters lay upon their surface, as they do in other birds, and that their dif- 

 ferent branches, coming from all the parts of the kidney, of which the superior 

 was very conspicuous, entered the kidney about its middle, and formed there a 

 very large pelvis. 



The liver was in one cavity with the heart, of which it covered near one half: 

 it had no gall-bladder, and but one ductus bilarius, inserted into the duodenum, 

 about 1 inches below the pylorus, which seemed to have an immediate com- 

 munication with the vena porta;, because, by blowing into it, this latter was 

 also distended. The heart and liver were separated from the intestines by a 

 membranous diaphragm. Both heart and liver were suspended by one common 

 mediastinum, by tlie help of its several membranes, and 8 strong muscles on 

 each side, arising from the upper part of the ribs, going from thence over the 

 lungs, and ending in a very strong tendinous membrane, which is inserted into 

 the spina dorsi. 



The liquor, contained in the pericardium, was small in quantity, and per- 

 fectly transparent. 



The lungs lay under the diaphragm and its muscles, in a deep cavity, formed
