PHASIANUS PICTUS. 295 



from them. This I could see plainly was the case in this kidney ; 

 therefore shoidd be ready to think it was so in all. 



In a guinea-cock, after carefully dissecting the ducts of the liver, 

 they appeared as follows : — the ductus hepaticus passes on by the right 

 side of the gall-bladder, adhering to it, to the intestine; the ductus 

 cysticus arises from a little pouch on that part of the bladder that 

 adheres to the liver : this pouch communicates with the bladder by a 

 small hole, and into this pouch enters the cyst-hepatic duct. Prom 

 this structure we see that there must be regurgitation even into the 

 cyst-hepatic, for the bile must come into this pouch, and then it can 

 either go on to the gut, as in the human, when it has got into the 

 ductus communis, or it may be thrown into the bladder ; so that here 

 is the same mechanism as in the human subject, or what answers the 

 same end; and besides this mechanism, there is what is called the 

 hepatic duct in the bird. 



I could see but one pancreatic duct, and that and the two biliary 

 ducts entered by one orifice only through the inner membrane, though 

 by distinct ones through the outer. The length of the bile-ducts was 

 about two inches. The caeca were very long, and rather wider than a 

 cock's. This animal died of a seeming disease in the head, for it began 

 to swell about the eyes. 



The Argus Pheasant [Phasianus Argus, Linn.] . 



The viscera of this pheasant are similar to those in the common fowl, 

 excepting that the duodenum is considerably longer. There is a crop ; 

 the gizzard is strong : the duodenum is long, passing down on the right 

 and then making a sweep towards the left : the jejunum and ileum are 

 loose intestines strung on the right and lower edge of the mesentery ; 

 and the ileum before its termination passes up behind the others, 

 towards the posterior surface of the root of the mesentery; being in 

 this passage attended by the two caeca one on each side, united to the 

 ileum by a narrow mesocaecum. At this part the intestine is attached 

 to the root of the mesentery, and to the back; and, where the two 

 caeca open into the gut, commences the rectum, at which part there is 

 a band ; the rectum passes down the back. The liver, spleen, and pan- 

 creas are as usual. 



The Golden Pheasant [Phasianus pictus, Linn.]. 



In the golden pheasant the ducts of the liver enter the duodenum at 

 the last turn ; the pancreatic duct enters at the same place. The intes-
