portal fissure, and a smaller right part passing out into the processus caudatus, or caudate lobe, 
which connects it (Fig. 716) with the under or visceral surface of the right lobe. 
The posterior surface of the Spigelian lobe is free ; it is placed vertically, and looks backwards 
and slightly inwards. The lobe has also another surface, which is hidden when in the body and 
in the hardened liver by the folding of the left lobe across it. By this folding there is formed a 
deep fissure (fissure of the ductus venosus), at the bottom of which will be found the remains of 
the ductus venosus. 
(5) The Gésophageal Groove is situated on the back of the left lobe, to the 
left of the upper end of the Spigelian lobe, but separated from it by the fissure of 
the ductus venosus (fossa ductus venosi), which on this aspect indicates the division 
between the right and left lobes. The groove leads down into the gastric impres-

Fic. 716.—THE LIVER FROM BELOW AND BEHIND, showing the whole of the visceral surface and the posterior 
area of the parietal surface. The portal fissure has been slightly opened up to show the vessels passing 
through it; the other fissures are represented in their natural condition—closed. In this liver, which 
was hardened in sifu, the impressions of the sacculations of the colon were distinctly visible at the colic 
impression. The round ligament and the remains of the ductus venosus are hidden in the depths of 
their fissures. 
sion on the visceral surface of the left lobe (Fig. 716), and, when in the body, lies 
in contact with the prominent right or anterior margin of the cesophageal orifice 
of the diaphragm (see p. 990 and Fig. 724), sometimes also with the cesophagus 
itself. 
The superior area of the parietal surface lies in contact with the roof of the abdomen ; it is 
convex on each side, and depressed near the middle line. The two convexities, of which the 
right is the more prominent, fit into the two cupole of the diaphragm ; whilst the central 
depression (depressio cardiaca) corresponds to the position of the heart. This area (with the 
exception of a small triangle at its posterior part, between the separating layers of the faleiform 
ligament) is completely covered by peritoneum, and on it the division of the liver into right and 
left lobes is indicated by the attachment of the falciform ligament. 
The anterior area of the parietal surface is triangular in shape, and after death is usually 
flattened, owing to the falling in of the anterior abdominal wall. In part it lies in contact with 
the diaphragm, which separates it from the rib-cartilages on each side, but at the subcostal
