 upper part of the renal impression on the right side, as far as the 

 Spigelian lobe in the middle, and it includes the whole of the left 

 lobe except a small part to the left of the Spigelian lobe which lies 

 upon the oesophagus.

 narrow on the left. In the centre is a hollow for the spine, upon 

 which the Spigelian lobe lies, to the left of this is the depression for 

 the oesophagus, and to the right the inferior vena cava is partly 

 embedded in the liver. On the right of the cava, the surface is 

 rough between the layers of the coronary ligament where it was 

 adherent to the diaphragm ; and close to the vein is a small hollow
