The upper incisors very small, placed vertically, a considerable space 

 existing between the two middle ones. The lower incisors long, very 

 narrow, projecting horizontally, and closely approximated. 



The stomach was simple, almost globular in form ; the oesophagus 

 entered far to the right, the cardiac orifice very nearly approaching 

 the pyloric, so that while the greater curvature measured 6^ inches, 

 the lesser was but f of an inch. The small intestines were wide, 

 46 inches in length. The caecum was nearly 5 inches long, wider 

 near its commencement than any part of the intestine, and slightly 

 sacculated, but tapering and becoming smooth towards the extremity. 

 The ileum entered thecolon at avery obtuse angle, andthere was scarcely 

 any difference in the calibre of these two parts of the intestine. The 

 colon was without sacculations and peculiar in form, being widest at 

 the upper end, then gradually contracting till it became narrower 

 than any part of the intestine, and dilating again into the rectum ; 

 and this appeared not to be the result of muscular contraction, as it 

 retained this form after macerating in water several days and then 

 inflating. The length of this part of the intestine, from the ileo-caecal 

 valve to the anus, was 18 inches. 



The liver presented three very distinct lobes : the left one was en- 

 tire ; the middle cleft into three by two fissures on its under surface, 

 in one of which (that most to the right) the gall-bladder was placed ; 

 the right lobe was entire, but on its under surface was placed the 

 lobulus Spigelii. 



The gall-bladder was pyriform ; the duct, 3 lines in length, join- 

 ing the hepatic duct, formed the common gall-duct, which was half 

 an inch long and entered the duodenum one inch from the pylorus. 



The spleen was long, narrow and flattened, half an inch wide at the 

 broadest part, and 2 J inches in length. 



The kidneys, simple, large and oval, were 1 inch long and 8 lines 

 broad; the right one situated nearly the whole length of the kidney 

 higher than the left. 



The penis was 3 inches in length, containing a bone 1 1 lines long. 

 The skin of the glans covered with minute spines or tubercles, which, 

 when examined microscopically, were found to be tooth-like bodies, 

 most having two points, some one, others three or more^ all directed 



backwards. '■'•/''/V^*!'"'"' "^"' "•' j 



The testes were oval, 8 lines long, 5 broad. '"•* 9/11 lA ,og ■'Mu^d 

 The vesiculse seminales consisted of two large simple culs-de-sac, 



7 lines in length. 



On opening the thorax the left lung was found to have two lobes, 



the right four. 

 ^ ; ' The heart presented nothing unusual. From the arch of the aorta 



two large vessels arose, the first giving rise to the innominate and left 



carotid ; the second being the left subclavian. 



On examining: the brachial and femoral arteries, no division into 



smaller trunks, forming a rete mirabile, as is observed in several 



animals belonging to this family, was discovered. The brachial artery 



perforated the humerus near its lower extremity. 



The tongue was long and narrow, 2^ inches long from the root of
