birds and of some few mammals. It has longitudinal bands along the 

 inner surface and is very thick-coated. Intestines about 4f lengths of 

 the animal, that is, somewhat shorter than in maturity; 4. 10^- long, 

 of large equable diameter, void of ccecum, and exhibiting on their inner 

 surface nor valves, nor folds, nor other retardatory processes, not even, 

 I think, a valvula coli to distinguish the small from the great intestine. 

 And, in fact, no such distinction has place, the intestinal canal being of 

 equal breadth throughout and similar aspect internally,* save the last 

 6 inches, which are wider, thicker-coated and furnished internally with 

 longitudinal bands, not unlike the post ventricle above noticed. 



Kidneys 1 inch long, elliptic and lobulated, there being 3-4 distinct 

 divisions of the body of the organ under the strong and uniform cortical 

 substance or cover. 



Soft anatomy. {Female.) The liver has 7 divisions in all ; the right 

 and left lobes about equal and bifid, but very unequally so ; the central 

 lobe, smaller and trifid. 



The elliptic gall-bladder is freely suspended between the larger 2 lo- 

 bules of the central lobe and discharges the bile into the intestine by a 

 large clear duct about 2 inches long, and which enters the intestine 

 about that distance from the stomach. The lungs have 4 chief divi- 

 sions, but 6 in all, the 2 latter being very subordinate. The spleen is 

 dark-coloured, tongue-shaped, and lies along the stomach longitudinally 

 and centrally on its outer arch. The pancreas, in form, structure, and 

 position as noted in the male, seems to discharge the pancreatic juice 

 into the intestine just below where the bile enters it. The intestines 

 are 4. 9|-, of one equable diameter of half an inch, and void of ccecum 

 or valves internally. The stomach is a large, membranous and simple 

 sack, showing something of muscularity without, but no folds or bands 

 of any sort within. I could not satisfactorily determine the form of the 

 uterus in this young subject. 



Hard anatomy. {Male.) Cervical vertebrae 7, dorsal and ribs 15, 

 lumbar 5, sacral 3, caudal 18.f Total 48. Carpal bones 7, metacar- 



* This remark refers to salient retardatory, and not to minute secretory, processes 

 (villi) characterising the inner surfaces of various intestines. 



t I have some doubt as to the number of sacral and caudal vertebrae, because the 

 former are not clearly distinguished from the proximate vertebrae by any of the 

 usual signs of anchylosis, depression, &c. The circumstances which have determined
