called Lobulus Caudatus, and is lost gradually on the under 

 surface of the great lobe, by inclining to the right. 



The Lobulus Quartus, or Anonymus, is not by any means so 

 elevated as the last, but having a flattened surface, is placed in 

 front of the transvere fissure, between the fore end of the um- 

 bilical fissure and the gall-bladder; its posterior extremity is 

 the second porta of the Liver, and is just opposite to that fur- 

 nished by the Lobulus Spigelii. 



The liver, from being completely enveloped in peritoneum, 

 has a smooth glossy appearance. The reflections of this mem- 

 brane, from it to the parietes of the abdomen, form the liga- 

 ments, as they are called, which consist each of two lamina?. 

 The Falciform Ligament, or Suspensory, containing in its an- 

 terior margin the remains of the umbilical vein, now called 

 Ligamentum Teres, begins at the umbilicus, extends from it 

 along the linea alba and the middle line of the diaphragm, 

 and, as mentioned, is reflected to the upper surface of the liver, 

 from the anterior to the posterior margin. The Right Late- 

 ral Ligament is situated behind, and departs from the back 

 part of the diaphragm to the posterior margin of the right 

 lobe. The Left Lateral Ligament also goes from the back 

 part of the diaphragm, and is attached along the posterior 

 margin of the left lobe. Where the suspensory ligament in- 

 clines on each side into the lateral, it passes with so much ob- 

 liquity as to leave some portion of the posterior margin of the 

 liver uncovered by peritoneum ; the latter, where it describes 

 the periphery of this space, has been rather unnecessarily de- 

 signated as the Coronary Ligament. 



In addition to the peritoneal coat, the liver has another, con- 

 necting it with the peritoneum, and seeming to be only con- 

 densed cellular substance, which also penetrates into the sub- 

 stance of the gland, and holds its constituent parts together. 

 It is particularly well seen within the circle of the coronary 

 ligament. 



Of the Organization of the Liver. 



The glandular substance of the Liver is fragile and easily 

 lacerated; and consists of a congeries of spherical or polyhe- 

 drical grains, called acini from their resemblance to small ber-
