In case II (Fig. 2) the gall-bladder occupied its usual position. The 

 pancreatic bladder was about two-thirds the size of the gall-bladder. It 

 occupied a position caudal to the gall-bladder, with which it was loosely 

 united by connective tissue. The duct coming from the pancreatic 

 bladder passed obliquely over the ductus cysticus and the right branch 

 of the ductus hepaticus, and, after running parallel to the ductus chole- 

 dochus, joined the duodorsal division of the ductus paucreaticus 11.5 mm. 

 from its union with the splenic division. In size the liver and pancreas 

 were normal. The lobation of the liver was normal, except that the left 

 lateral lobe had a deep incision extending from the porta hepatis trans- 

 versely across it, nearly subdividing it into two portions.

Fig. 1. Diagrammatic outline of the liver and a portion of the pancreas and duodenum 

 in Case I. The liver has been turned cephalad. The pancreatic ducts and bladder are 

 represented in solid black; the gall-bladder and bile ducts in outline. Note that the 

 pancreatic bladder occupies the usual position of the gall-bladder, while the latter lies 

 caudal to it resting on the right median lobe of the liver. The two small ducts mentioned 

 in the text can be seen below the point of union between the pancreatic cystic duct and the 

 duodorsal division of the ductus pancreaticus.

 in Case II. The liver has been turned cephalad. Pancreatic bladder and ducts black ; gall- 

 bladder and ducts in outline. The gall-bladder in this case occupies its normal position. 



In case III the gall-bladder was the larger of the two and occupied 

 its normal position. The pancreatic bladder was half the size of the 

 gall-bladder and firmly attached to it by a strong sheet of connective 

 tissue. The course of the duct was as in case II. It joined the duo- 

 dorsal division of the ductus pancreaticus 7 mm. from its union with 

 the splenic division. Just before its union with the main duct of the 

 pancreas a few small ducts coming from the adjacent part of the pan- 

 creas joined it. The left lateral lobe of the liver was somewhat folded
