In addition to the splenic artery and veins whichenter the spleen at the hilum, there is a leash of vesselswhich enter the spleen through what Richards calls a sec-ondary hilum near the lower pole. These vessels are car-ried in a fold of peritoneum that is reflected on the surfaceof the splenic flexure of the colon. The capsule of the spleen is so firmly adherent to thesurface that attempts at separation would be attendedwith laceration of the pulp; therefore a subcapsular sple-nectomy is not feasible. A knowledge of the relationship of the spleen to thecontiguous structures is of practical moment. The supe-rior pole is in close relation with the diaphragm and the lUll. X. The relationship of the tail of the pancreas to the posterior aspect of the pedicle. PLATE XI
