Miller—Distribution of the Bile Ducts of the Cat. 629 
cysticus. The duct from the caudate lobe joins the ductus 
cysticus, the same as in figure five. 
Fig. 7. Case 11. No ductus hepaticus dexter present. The ducts 
from the lobes of the right half of the liver are independent 
of each other; those coming from the right median and the 
cranial division of the caudate lobe join the ductus cysticus, 
while the duct from the caudal division of the right lateral 
lobe joins the ductus choledochus within the folds of the 
ligamentum hepatoduodenale. On the left side the duct 
from the caudate lobe joins the ductus choledochus and the 
ducts from the caudal portion of the left lateral lobe unite 
to form a single duct which passes through the caudate lobe 
and joins the ductus choledochus within the folds of the 
ligamentum hepatoduodenale. 
Fig. 8. Case 70. The ductus hepaticus dexter et sinister is present. 
The ductus cysticus joins the ductus hepaticus dexter some 
distance before it unites with the ductus hepaticus sinister. 
The duct coming from the caudal division of the right lat¬ 
eral lobe passes behind the ductus hepaticus dexter and 
joins the main duct coming from the left lateral lobe.
