cms of the diaphragm, the vena azygos major vein, the thoracic 

 duct, and the junction of the splenic and superior mesenteric 

 veins to form the portal vein, near the upper border. To the 

 right is the second portion of the duodenum, which it over- 

 laps, and the common bile duct; to the left it passes behind 

 the fourth portion of the duodenum. 



The neck is about 1 inch long, flattened from before back-

The Body. In front the anterior surface is in relation with 

 the posterior inferior surface of the stomach, the lesser peri- 

 toneal sac intervening. The posterior surface is devoid of 

 peritoneum, and rests on the aorta, the left kidney and its 

 vessels, suprarenal gland, splenic vein, near its upper border, 

 the crura of the diaphragm, and the origin of the superior 

 mesenteric artery, the inferior mesenteric vein, as it passes 

 up to open into the splenic vein. Below the inferior surface 

 is the duodenojejunal fold, and to the left the splenic flexure 

 of the colon. The superior border is in relation with the celiac 

 axis, its hepatic branch to the right, and splenic artery on the
