is separated from it by the fossa for the ductus venosus. The groove leads down 

 into the gastric impression on the inferior surface of the left lobe (Fig. 938), and, 

 when in the body, lies in contact with the prominent right or anterior margin of 

 the oesophageal orifice of the diaphragm (see p. 1152 and Fig. 912), sometimes also 

 with the oesophagus itself. 



Facies Inferior. The inferior or visceral is an irregular, obliquely sloping 

 surface (Fig. 938), which looks downwards, posteriorly, and to the left, and rests 

 upon the stomach, lesser omenturn, intestines, and right kidney. The division 

 into right and left lobes is indicated on this surface by the left sagittal fossa, 

 which passes from the umbilical notch at the anterior border back to the porta 

 hepatis, and thence backwards as the fossa for the ductus venosus. 



The inferior surface of the left lobe is directed downwards and posteriorly, and

rests on the superior surface of the stomach, in front of the cardia ; also on the 

 lesser curvature with its attached lesser omentum. The part which rests upon 

 the anterior surface of the stomach is rendered concave by the pressure of that 

 organ (Fig. 938), and is known as the impressio gastrica ; whilst the portion to the 

 right of this, being free from the pressure of the stomach, projects backwards over 

 the lesser curvature against the lesser omentum in the form of a smooth rounded 



minence, and is known as the tuber omentale. 



The inferior surface of the right lobe may be divided into two portions by the 



e of the gall-bladder, which extends forwards in its fossa to the anterior sharp 

 margin of the liver (Fig. 936).

The quadrate lobe is of an oblong shape, the antero-posterior diameter being the greatest Its 

 " ce is generally concave, and is related to the pylorus and the adjacent parts of the stomach 

 duodenum, when the former is distended. When the stomach is empty, however, the
