a course of rather more than i inch downwards and to the right, it 

 joins the cystic duct, and so gives rise to the common bile-duct. 

 The diameter of the hepatic duct is about \ inch. 



The gall - bladder is a reservoir for the bile. It is pyriform, 

 and is situated obliquely on the inferior surface of the right lobe, 

 where it occupies the cystic fossa, having the quadrate lobe on its 

 left side, and a large part of the right lobe on its right side. It 

 extends from the anterior border of the liver to near the portal 

 fissure, and presents a fundus, body, and neck. The fundus, 

 which is round, looks downwards, forwards, and to the right. It 

 occupies the cystic notch on the anterior border, and is in contact

with the anterior abdominal wall opposite the ninth right costal 

 cartilage, at the outer border of the right rectus abdominis muscle. 

 The body is directed upwards, backwards, and to the left. Its 

 inferior and lateral surfaces are free, but superiorly it is attached 

 by areolar tissue to the cystic fossa. It rests upon the right end 

 of the transverse colon and the first part of the fluodenum. The 

 neck describes two curves like the letter S, after which it is continued 

 into the cystic duct. The gall-bladder is usually covered by peri- 

 toneum, except on its upper surface. Sometimes, however, the 

 serous membrane entirely surrounds it and forms a ligamentous 

 fold above it, by which it is loosely and movably suspended
