broadly attached to the substance of the right lateral lobe. The lower 

 border of this elevation is slightly excavated to receive the corresponding

 united over this by hepatic tissue to the caudate. This liver is further 

 remarkable for the great tendency it has to subdivision, numerous fissures, 

 of varying sizes and depths, being developed along the margin of the 

 chief lobes. Their position and relative size will be better understood
