MACACUS NEMESTRINUS. 15 



that flat surface : it had a long vena cava inferior. The pericardium 

 does not adhere to the diaphragm : there are two arteries arising from 

 the curve of the aorta. 



The duodenum is not anywhere entirely covered as in the human, 

 where it passes behind the colon and mesentery ; for the colon is loose 

 everywhere, excepting that it is rather more bound at the transverse 

 arch than in the angle. The csecuni is rather longer than that of the 

 human ; there is no appendix caeci ; the colon [measured] one length 

 and a quarter [that] of the animal ; the small guts two lengths and a 

 half. I could not observe any valvulae conniventes. The liver is made 

 up of four lobes. The gall-bladder is attached to the third from the 

 right lobe, which is the largest. The left kidney was a little lower than 

 the right. The capsula renalis has much of the texture of that in 

 the human. 



The scrotum is not very large, and not so distinct from the other 

 skin and cellular membrane as it is in the human, so that when the 

 testicles are squeezed out it is pretty flat. The penis is something like 

 the human, but has a much longer preputium, more like that in brutes 1 , 

 for it is attached to the penis half-way down, so that the angle of re- 

 flection is about the middle of the penis ; and, when it is brought over 

 the glans in the flaccid state of the penis, all the skin of the penis is like- 

 wise brought over, so that the penis is entirely hid, as it were, in the 

 common skin. 



The testes, tunica propria testis, and the tunica vaginalis of the 

 spermatic chord, are all like those in the brute. On the right side it 

 seemed to be diseased, and there was a kind of hernia made by the 

 epiploon, and just above the tunica propria there was the septum as it 

 is called. But I suppose all this was from disease, as there Avas nothing 

 of this sort on the left side. 



The erectores penis are very large, and do not seem to take their 

 origin from the ischium, but from the body of the eras, and are inserted 

 into it again ; so that they are farther on the penis than common, and 

 between them is almost hid the urethra. The acceleratores seminis are 

 very strong, are not lost in the body of the penis, nor do they come so 

 far up as the erectores do, so that between the erectores is only the 

 urethra. The membranous part of the urethra is pretty long, because 

 the ossa pubis are broad, and the membranous part is plainly muscular. 

 Cowper's glands are very large, but I could not find their ducts. The 

 urinary bladder is more prominent than in the human ; there is a 

 pretty thin adhesion between the bladder and rectum, not by such
