CHELONE MYDAS. 351 



with a sediment in which it could not pass the duct. The cystic duct 

 is larger, straight, and not very long, opening into the duodenum, about 

 two inches beyond the pylorus. There is a long hepatic duct from the 

 left side or end of the liver, which runs externally to the liver, between 

 it and the transverse pancreas, making in its passage several turns : it 

 joins the right hepatic duct, and the common trunk joins the cystic not 

 far from its entrance into the duodenum. There are no hepato-cystic 

 ducts 1 . 



The pancreas is similar to that of a fowl's, viz. it is divided into two ; 

 one running in the curve of the duodenum and stomach, and the other 

 in the contrary direction : the duct enters near the ducts of the liver. 



The spleen is a rounded body situated in the middle of the body 

 behind the upper part of the intestine at the root of the mesentery, 

 adhering to the pancreas ; very much like the kidney of a lion in shape, 

 having its veins passing on the outside 2 . The arteries are very small. 



The kidneys are situated at the lower part of the abdomen, covered 

 by other bodies, and smoothed over by the peritoneum, so as not to be 

 seen at first. They are flat on the anterior surface and a little rounded 

 behind ; are convoluted like a fowl's ; and have their vessels enter at 

 its anterior surface 3 . The ureter comes out at the anterior surface and 

 lower end of the kidney, and enters the bladder near its opening into 

 the rectum by a flattened protuberance. The bladder is an oblong body 

 and pretty loose 4 : the urethra, or opening, is large, and, as it were, of 

 no length. The urine is not very thick; but the bladder was lined 

 with a thick mucus, which made us suppose it to be urine, as there 

 was no other urine in the bladder. 



The Male Parts. — The testes are oblong bodies lying upon the kid- 

 neys, much in the same place with the ovaria. They are thick at their 

 anterior ends, and become smaller and smaller to their posterior parts, 

 and ending almost in a point. They adhere by a very narrow line, so 

 that they can be turned from one side to the other. In texture they 

 are extremely spongy or cellular, so as to be easily inflated by blowing 

 by a pipe into their substance. They are of a cream colour through 

 their whole substance 5 . "Where they adhere to the kidney, pass out 

 the ducts, which form the vasa deferentia. These proceed in a contorted 

 or convoluted manner along the surface of the kidney, adhering to it, 

 and pass into the union of the bladder and rectum, and open into the 

 upper part of what may be called the urethra, each by a prominent 

 nipple flattened from side to side 6 .
