between the rami of the ven. portae to the right lobe of the liver, 

 gives off art. cystica, which, with a branch above and below the 

 gall bladder, passes from neck to fundus. 



b. Ram. gastro-duodenalis, passes downwards between the commence- 

 ment of Duodenum and the head of the Pancreas, and from pylorus 

 along the great curvature between the layers of the great omentum. 

 Branches : 



1. Pancreatico-duodenalis, passes downwards on the pars descend, 

 duodeni, between it and Pancreas, gives off artt. pancreatic, dex- 

 trtB and duodenales, which anastomose with jejunales ofmesenter. 

 superior. 



2. Gastro-epiploica dextra, is that portion of ram. gastro-duodenal. 

 which passes along the great curvature, gives branches to the 

 anterior and posterior surface of the Stomach, and six to eight rr. 

 tpiploici, which descend between the laminae of the great omen- 

 tum. Anastomoses at the fundus ventriculi with coron. ventric. 

 sinistra. 



3. Lienalis, the splenic artery the largest branch of the coeliac passes 

 very tortuously along the superior border of the Pancreas (in a sulcus) to 

 the left, and enters the spleen at the hilus divided into (four to ten small, 

 or two principal) branches. Situation : behind the stomach. 

 Lateral branches : 



a. Artt. pancreaticee (four to six), tolerably large, to the left portion of 

 the Pancreas. 



b. Art. gastro-epiploica sinistra descends before the cduda pancreat., 

 behind the fundus of the stomach, passes to the left part of the great 

 curvature, and gives ascending branches into the left part of the great 

 omentum. 



c. Art. breves (two to six), arise from one or several terminal branches 

 close to the Spleen, and pass backwards to the fundus, as high up- 

 wards as the cardia of the Stomach. 



2. Mesenterica s. mesaraica superior (seven to eight inches long) supplies the 

 small intestines and the right half of the large. Or. : close (one inch) below 

 cceliaca. Course : between the laminae of the mesentery in the root, as far 

 downwards as the right iliac fossa, a little to the left and below curved ; it is 

 lost, becoming very small in the coecal region. 



Situation : at first behind Pancreas, between it and Aorta, then separated 

 from this by the boundary bet ween duodenum and jejunum, as it enters below 

 the Pancreas into the root of the mesentery. Branches for Pancreas; for the 

 small intestines from the left convex, for colon and ccecum from the right con- 

 cave side. 



1. Artt. intestinales (s. jejunales et ileai), ten to fifteen larger (eight to 

 twelve smaller) branches, which pass downwards and forwards for two 

 to three inches in length, then divide and unite in loops or arches with 

 one another. After a threefold division and junction, branches pass off
