theirs, was fastened along the duodenum, inclining more towards the right 

 kidney than the left; but though very small in theirs, it was very large in ours. 

 The mesentery in ours, as in theirs, was filled with a very hard fat, which 

 inclosed and almost concealed all its vessels. The intestines in theirs were ^ 

 feet long, and all of one thickness, having nothing to distinguish them; but 

 in ours they were only 42 inches and a half. Theirs had no caecum, but we 

 found it in ours, at the upper end of the rectum. The bladder was very large; 

 the right kidney in ours, as in theirs, was a great deal higher than the left, and 

 covered with the lobes of the liver. The lungs in theirs had 5 lobes, 2 on the 

 right side and 2 on the left, and the 5th in the mediastinum, which was as thin 

 as a spider's web : but in ours there were 7 lobes, 3 on the right and 3 on the 

 left, and the 7 th in the middle. The heart in ours, as in theirs, resembled 

 that of a dog, having the right auricle exceedingly large, and as they found a 

 great deal of slimy matter hardened in the right ventricle, so we found in ours 

 a polypus. The musculus crotophiLes passing under the zygoma was in ours, 

 as in theirs, fastened there, being very fleshy, even to its insertion, made by 

 a very large tendon, which was inclosed between 2 pieces of flesh, much thicker 

 than those which are generally found in this place, and which are thought to 

 be put there to defend and strengthen the tendon of the muscle of the 

 temples. 



The tendons in the articulations of the fore feet were very large and strong. 

 In ours we observed 2 glands on each side of the anus, with a passage to each 

 of them, full of a greyish foetid matter. The orbita in ours, like theirs, was 

 not bony throughout, but it was supplied in the upper part by a cartilaginous 

 ligament, which joined the apophysis of the os frontis to that of the first bone 

 in the upper jaw. The bone which separates the cerebrum from the cerebel- 

 lum was like that in dogs. The dura mater in ours did not adhere to the 

 cranium, as in theirs. The sinuses of the os frontis in ours, as in theirs, was 

 full of matter, like a friable fat. The mammillares processus, in ours, as in 

 theirs, were very large. In the eye both of them agreed exactly, the globe not 

 exceeding 44- lines in diameter, the aperture of the lids being much larger, and 

 the pupilla being as large as the whole globe of the eye ; the crystalline contained 

 3 lines in breadth, and 1\ in thickness, and was more convex inwards than 

 outwards; this thickness of the crystalline made the two other humours to be 

 less in quantity. The choroides was all over of the same colour, viz. of a sqv^^ 

 brown red, without any tapetum, which is hardly ever wanting in the eyes of 

 other animals. 



I believe the academicians are misinformed, in saying that they carry their 

 tails erected, at least the tail of this was always trailing on the ground; neither
