quadrate and right median lobes ventral to the gall bladder in such 

 a manner that the fundus of the gall bladder was hidden from view 

 and the gall bladder itself slightly constricted. The bile ducts followed 

 one of the common types in their distribution. 



Closely united with the gall bladder and situated to its left was 

 a second bladder of nearly the same size. This was connected with 

 a duct which crossed the ductus cysticus obliquely and followed along 

 the right side of the ductus choledochus until just before its entrance 

 into the duodenum; it then passed dorsal to the ductus choledochus 

 and joined the splenic division of the ductus pancreaticus 7 mm from 

 its union with the duodorsal division (Fig. 1). 



Comparing the present case with the five preceding cases, it will 

 be seen that the pancreatic bladder occupies a special depression to 

 the left of the gall bladder in the quadrate lobe; it is more closely 

 connected with the gall bladder than in the previous cases there being 

 only a very thin, double-walled septum between the two bladders. 



The course of the duct coming from the pancreatic bladder is 

 quite similar to the previous cases but it differs from all the others 

 in that it joins the splenic division of the ductus pancreaticus. In 

 one other case (that of Gage) part of the contents of the pancreatic 

 bladder was discharged into the splenic division, the remainder into 

 the ductus pancreaticus. 



It may be of interest to note that two of the three cases I have 

 previously reported came from the same farm house while the third 

 came from a neighboring house. In the present case there is little 

 probability of any relationship to the former, for it came from a place 

 many miles distant from the farm houses above mentioned.
