MORPHOLOGY OF THE 



and left lateral lobes. The former aids in the formation of 

 the summit of the dome, and is in relation with the dia- 

 phram and Tvith the ventral abdominal wall. The left 

 lateral is a much larger lobe. It is in relation with the ven- 

 tral and lateral walls of the abdomen, while its caudal sm^- 

 face is closely apphed to the stomach. 



The right half of the hver comprises fom^ lobes and is 

 much less regular in shape. The right central and caudate 

 are the only lobes to be seen in a ventral ^iew. The former 

 is very extensive and forms the right half of the dome. Its 

 cephaUc surface is in relation with the diaphragm, its ventral 

 and lateral sm-faces with the abdominal waUs, and it is

partially subdivided by a deep fissure, in which the gaU 

 bladder is lodged. Its caudal smiace is in relation T^-ith the 

 pylorus, and with the junction of the first and second por- 

 tions of the duodenum. 



The right lateral is a smaU lobe, and one which varies 

 very much in size. 



It is wedged in between the right central and caudate 

 lobes, usually separated from each by a fissiu-e, and its dor- 

 sal sm-face is overlapped by the former and its ventral sur-
