The external sur-face of the spleen, incontact with the dia-phragm, IS describedas lying in contactwith the ninth, tenth,and eleventh internal surface,in its anterior por-tions, is in relation with the cardiac end of the stomach—behind,with the left crus of the diaphragm and the left supra-renal cap-sule; and below, with the tail of the pancreas. Its relations withthe stomach are liable to be disturbed by the movements of thatorgan. As to the margins of the spleen : at the top, where thesuspensory ligament is given off, it is blunt and rounded; thelower extremity is pointed, and normally lies over the junction.

The average dimensions of the spleen,in the adult, are : five inches in length, three or four in breadth,and from an inch to an inch and a half in thickness. Its weightis about seven ounces. The structures in the gastro-splenic omentum, venous andarterial, which go to form the pedicle in splenectomy are ofimportance. The splenic artery, the largest branch of thecoeliac axis, pursues a tortuous course behind the upper borderof the pancreas from the aorta to the spleen. In its course itgives off small bran
