these following observations. 1st. The guts were very much distended and 

 transparent, and through them appeared the faeces very liquid, accompanied 

 with no small quantity of wind; the end of the rectum was entirely closed like a 

 bladder, and sealed as it were hermetically, pendulous in the cavity, and not in 

 the least continued to a sphincter, of which there was no sign. 2dly, There 

 was no bladder to be found, nor uterus, nor any mark of what sex it was de- 

 signed for. 3dly, To supply the place of a bladder, both the ureters were in- 

 serted into the rectum within an inch or thereabouts of the end. 4thly, The 

 stomach was full, even to distension, of a hard substance, which being opened 

 was exactly the same to appearance with hard pressed curds. 5thly, The chyle 

 came freely enough out of the ductus Pecquetianus, where it was inserted into 

 the jugular, on the smallest pressure of the intestines. 6thly, I could not urge 

 the liquid or flatulent contents of the guts upwards within 1 inches of the 

 pylorus, though I pressed them till they broke, which hindered the inquiry 

 after a valve, that possibly might be there, to hinder the regress of any thing 

 to the stomach.
