the teeth opposed to them, throughout the whole length of their con- 

 tinuous surfaces. The second, third, and fourth molars of the upper 

 jaw have each a small additional, but less elevated, point on the external 

 anterior angle, increasing somewhat in size from the second tooth back- 

 wards. On cutting through the palatine bones for the more complete 

 removal of the brain, the crown of another molar tooth was found on 

 each side, posterior to, and somewhat within the line of range of the 

 last exposed molar. This tooth is represented in the plate annexed, 

 and exhibits the fifth tubercle of yet increased magnitude. 



The skin having been taken off for preservation, the cartilage of the 

 septum narium was observed to be thick and strong, and the central 

 ridge of the cranium very much elevated. The ligamentum nuchcE con- 

 sisted of three strong cord-like portions, two of which passing, in a 

 parallel direction, from the elongated spinous process of the first 

 dorsal vertebra, were inserted together upon the extreme superior pos- 

 terior angle of the central ridge of the cranium, supporting the whole 

 length of the elevated crest and mane. The third portion of this strong 

 ligament passed beneath the other two, to be inserted into the most 

 elevated part of the elongated spinous process of the vertebra dentata. 



The anterior portion of the sternum projected forwards, keel- like in 

 form and rounded. The ribs were twenty in number on each side, 

 the lumbar vertebrae four. The tracheal cartilages were firm, but the 

 rings were incomplete throughout; the lungs consisted, on the right 

 side, of one large and one small lobe; on the left, of one large 

 and two small lobes, bearing evident marks of inflammation. 



The pericardium was loaded with fat, and appeared of unusual 

 thickness; the heart presented nothing remarkable, but the arteries 

 v^rere particularly thick and firm in their coats. 



The (Esophagus was narrow, the stomach a single cavity, and rather 

 small, measuring, when moderately distended with air, but eight inches 

 from right to left, and 15^ inches in circumference; the jsaneie* thick- 

 ened about the pylorus, but as it was considered dearable to preserve 

 this organ entire, its internal surface was not examined. The stomach 

 contained a loose mass of tow, hair, string, and shreds of cloth. 



The spleen vras narrow, thin in substance, and 12 inches in length. 



The liver was distinctly divided into four lobes, two of which, one
