(Fig. 666) running from before backward. This fissure also divides the under 

 surface into a right and left lobe. The left lobe is variable, and usually consti- 

 tutes one-sixth of the gland. Three more lobes are seen on the inferior and pos- 

 terior surfaces of the right 

 one. from before back- 

 ward, the ijuadrate, the 



or tubereulum 



, and Spigelian 



Surfaces. The upe- 



or phrenic surface is 

 convex, directed upward 

 and forward and covered 

 by peritoneum except for 

 the linear space between 

 the layers of the broad 

 ligament. It includes the 

 upper surface of the right 

 and left lobes, the former 

 being convex and the lat- 

 ter more flat. Between 

 and upon the two is a 

 shallow depression or 

 flattening corresponding 

 to the central tendon of 

 the diaphragm and to the 

 heart. 



This separation of 

 lobes continues below in 

 the attachment of the 

 falciform ligament and in-

 i'-'il or interl'ibular notch. 



To the right of the 

 notch is a concavity in- 

 truding upon this surface, 

 occupied by the fundus 

 of the gall-bladder, the 

 /// ' < > cah's. This 



whole surface is in rela- 

 tion to the under surface 

 of the diaphragm, and 

 below to a small extent 

 with the anterior abdom- ? I ^ ? 1 



inal wall. 



The inferior or visceral surface is uneven, concave, and directed backward, 

 downward, and to the left. It is in relation with the stomach, duodenum, the 

 hepatic flexure of the colon, the right kidney, and suprarenal capsule. This 

 surface, as we have seen, is divided into a right and left portion by the left 

 longitudinal fissure. It is invested by peritoneum of the greater sac. except 

 where the <rall-bladder is adherent to it, and at the transverse fissure or hilus 

 where the two layers of lesser omentum are attached. 



The u/td, r sur/.n-e of the left lobe is moulded over the cardia of the stomach. 

 Near the centre and right part of this surface a result of moulding is seen in a 

 large rounded tubercle, the tuber omentale, which fits into the concavity of the 

 lesser curvature of the stomach. The whole tubercle is made from the under sur- 

 face of the left lobe and the lower left corner of the Spigelian. It is in front of
