CRQCODILIA. 339 



with the hepatic duct. These parts agree in every respect with the 

 same in some fowls, e. g., those that eat fish, especially with the fish- 

 hawk and eagle. 



The liver is large in proportion to the size of the animal ; it is pretty 

 uniformly concave below ; it is divided into two lobes, the right being 

 the larger ; this division is by the spine behind, and by the heart at 

 the fore and upper parts, so that almost the whole heart is sunk in the 

 upper convex surface of the liver ; but these two lobes are united by 

 the pericardium, above which adheres all round the surface of contact, 

 so that there is a capsula between the pericardium and liver, and the 

 tendinous membrane that covers the lower surface of the liver, but 

 there is a little continuation of the liver from the one lobe into the other, 

 just as in a fowl. 



The gall-bladder is fixed to the concave side of the right lobe, much 

 as in the human subject, but not so closely ; it is much of the shape of 

 that in the human, and is furrowed on the inside like a fowl's. The 

 hepatic duct, as it passes to the duodenum, sends a branch to the gall- 

 bladder ; it then goes to open, separately from the cystic, into the duo- 

 denum, but seems to be in conjunction with the pancreatic duct at its 

 insertion. The cystic duct arises from the lower end of the bladder, 

 is longer than the hepatic, is straight through its whole length, and 

 opens into the duodenum, by the entrance of the hepatic and pancreatic 

 ducts. 



There is an oblong dark body placed in the root of the mesentery ; 

 it is thicker at one end than at the other, is about two inches long, 

 and half an inch thick ; it has arteries running along one side of it, 

 and the veins seem to run principally on the outside. I imagine this 

 is analogous to the ' pancreas asselli,' viz. a lymphatic gland : it is a 

 good deal like the spleen of a bird, and as I could not find any ovaria, 

 I do not know but this may be them, but rather suspect it is not. The 

 crocodile, like the fowl, has no epiploon. 



The kidneys are very large, very nearly as large as in the human 

 body : they are situated on the pelvis something like those of birds ; 

 the upper end is largest and lies before the psoas muscles, and the lower 

 end passes into the sides of the pelvis. They are convoluted like the 

 brain, of a dark brown, in some places lighter ; are in contact with one 

 another, and have small bodies placed on the outer surface, as in the 

 kidneys of fowls L . Their ureters enter the sides of the anus, or the 

 rectum, after it has become valvular 2 . The ureters are as large as in the 

 human subject ; I should imagine that the urine was like that of birds,
