common ; but is divided at the right end or slit for the passage of the 

 mesenteric vessels, so that it is both before and behind them. 



The liver is divided into four lobes, besides the lobulus Spigelii ; the 

 second from the left is by much the largest, and its lower edge is divided 

 into three by pretty deep notches : the gall-bladder lies in the right 

 notch, the umbilical cord in the left ; it is some way from the dia- 

 phragm. The gall-bladder is pretty long and small : the cystic duct is 

 very short, and pretty large ; only about three-eighths of an inch in 

 length : there are three hepato-cystic ducts which are very small, and 

 enter the bladder near its opening into the cystic, upon that side next 

 to the liver : there are three hepatic ducts, all of which enter or join 

 with the cystic at one part. The ductus communis is short, and enters 

 the duodenum about an inch from the pylorus ; it runs some way in the 

 coats of the intestine, and then communicates with the pancreatic duct, 

 and these two make or open into a little bag 1 , which has an opening into 

 the duodenum. 



The veins of the liver are very large ; so is the vena cava, especially 

 where they all unite between the diaphragm and liver (but whether I 

 was deceived or not I won't pretend to say 2 ) : however, it [the inferior 

 vena cava] is very small before it passes into the heart, for it will hardly 

 admit one's little finger. The inferior vena cava divides just at the 

 liver, and the emulgents are inserted into these two, viz. vena cava and 

 iliac vein. 



The spleen 5 is a good deal the shape of a dog's. 



The membranous or muscular parietes of the abdomen are attached 

 or inserted along the outside of the thigh and knee of the animal, then 

 across the head of the tibia, from thence quite across the pubis ; for the 

 knee is no lower than the pubis, so that the fore and inner part of the 

 thighs, with the knee, make part of the abdomen, and of course are 

 seen in its cavity upon each side of the pelvis, or upon the spine of the 

 iliac bones. 



The legs, from the knee to the heel, are attached to the sides of the 

 pubis, and are at equal distances from the ossa pubis ; so that those bones 

 are opposite to the middle of the legs. 



The Eye i . — The glandula lacrymalis is but very small, as we may 

 suppose that there is no occasion for tears ; but when the animal is upon 

 land, it is situated as in common. There is no puuetum lacrymale, and

 structure in the seal tribe. See Hunt. Prep. Xo. 805.]
