The coats of the intestines, the peritonaeum, the 

 glands of the mesentery, with the lacteals and tho- 

 racic duct, are similar to those parts in man. The 

 course and termination of the latter, are precisely 

 the same. 



The length of the small intestines, from Feet, inch, 



pylorus to coecum = 18 8 



The length of the colon, 5 5 



The length of rectum, i .0 3 



— — — 



Making the length of the whole intestines, = 24 4, 

 or upwards of nine times the length of the body of 

 the animal ; — a proportion fully greater than what 

 we find in man, even in persons of short stature *. 



The liver is a large viscus, situated as in man. 

 It differs, in a few respects, from the description of 

 Dr Tyson. The sulci, in our animal, are deeper 

 than in the human liver ; and, in this respect, more 

 nearly resemble those of the baboon. The sulcus, 

 which divides the right arid left lobes, penetrates 

 through two-thirds of the substance of this organ. 

 The lobulus Spigelii is very distinctly marked ; and 

 there is a very small heart-shaped lobule loosely at- 

 tached to the posterior part of the great fissure on 

 the concave side of the liver. The left lobe is pro- 

 portionally smaller than in man ; but the substance 



* It may not be improper to observe, that the measurements 

 were made by a string applied along the convex edge of the 

 intestines, after the mesentery was divided.
