    lesser omentum in front of the portal vein and to the right of the hepatic artery (Fig. 1), to join the cystic duct at an acute angle. The ducts have an outer serous, a middle fibro- muscular, and an internal ]iiucous coat, the last being thrown into folds in the cystic duct, one of Avhich, larger than the rest, overhangs the entrance to the gall-bladder and acts as a sort of valve. These folds are usually described as being arranged in the form of a spiral, but this is not always well marked, and when distended the mucous lining of the ducts is free from ridges. The common bile duct, about three inches in length, has most important relations as it passes downwards and backwards to its termination, since it lies in front of the portal vein and to the right of the hepatic artery. Passing behind the first part of the duodenum, it continues downwards between the second part of the duodenum and the head of the pancreas, and before enterino- the intestine the duct runs obliquely for about three-quarters of an inch between its coats, forming an elevation beneath the mucous membrane, and becommg somewhat constricted before opening into the bowel, about four inches beyond the pylorus.
