the posterior edge 

 of the hver, called 

 the posterior notch, 

 whei'eby the liver is 

 adjusted to the verte- 

 bral column. The 

 anterior and poste- 

 rior notch divide the 

 liver into tico lobes, 

 the right of which is 

 much the larger and 

 thicker, and the left 

 terminates in a thin 

 cutting edge. 



The under surface 

 of the liver presents 

 a di^e^ fissure called umhilical or longitudinal, which reaches from 

 the anterior*^ to the posterior*'' notch, and contains the remains of 

 the umbilical vein, now the ligamentum teres, and the remains of the 

 ductus venosus. Sometimes this fissure is converted into a fora- 

 men,'' the right and left lobes being connected. At right angles to 

 this fissure, is another called the transverse fissure,^^ which contains 

 the portal vein, hepatic artery, and hepatic duct, bound together by 

 cellular tissue, which is called the capsule of Glisson. A deep de- 

 pression upon the under surface of the right lobe of the liver, paral- 

 lel with the longitudinal fissure, contains the gall-bladder ;*° that 

 portjon of the liver included between this depression and the lon- 

 gitudinal and transverse fissures is called the lohuhis quadratus^ or 

 quartus, from its shape. The lohuhis spigelii* is a small triangular 

 lobe at the posterior and inferior portion of the liver, and with the
