16 QUAD RUM AN A. 



broad surfaces as in the human, so that the vesicula? seminales may be 

 seen. 



The prostate gland is very like that of the human. The vesiculae 

 seminales are pretty large, are much like the human, and [their ducts] 

 enter like [those of] the human 1 . 



The muscles of the anus are like [those in] other brutes. 



[Albino Variety or a Macacus.] Bailey's Monkey, of 

 which I have a painting 2 . 



The caecum is loose and pendulous. The colon is attached to the 

 right side, just where it is going to make the transverse arch ; it then 

 goes across the body in very loose convolutions, and goes down the left 

 side without any attachment ; but on the mesocolon it is also thrown 

 into very large convolutions. The mesocolon is very long, which 

 admits of the colon varying its situation. The colon has three longitu- 

 dinal ligaments upon it. 



The epiploon is attached anteriorly to the spleen on the left, which is 

 rather lower down than common ; also to the great curve of the stomach, 

 to the beginning of the duodenum, to that part of the colon which is 

 fixed, and to a little part of the transverse areh : it then attaches itself 

 to the root of the mesocolon continued to the left side along the lower 

 edge of the pancreas near the spleen. 



The liver is principally on the right side, is divided into four lobes, 

 the three anterior making up the body of the liver, the posterior being 

 the lobulus Spigelii. Of the three anterior lobes, the left is the smallest 

 and thinnest. The right lobe is the next in size, and is thick ; the 

 middle lobe is the largest, into which passes the round ligament into a 

 pretty deep fissure. Upon the right edge of the third lobe is attached 

 the gall-bladder. 



The anterior mediastinum is a pretty broad membrane, so that the 

 heart is some way from the sternum. The lungs on the right side is 

 divided into three lobes, besides the lobe which passes between the heart 

 and diaphragm. The left lung is divided into two lobes. 



The tunica vaginalis testis communicates with the abdomen. 



The buttocks were covered with a bright red skin inclining to pink 

 or Modena, under which the tuberosities of the ischium are covered 

 with a great quantity of fat of a hardish texture, covering the bones 

 like a cushion, while the other parts are but lean.
