side opposite the insertion of the pronator radii teres. There is also a low 

 division of the brachial below the bicipital tuberosity into three branches, viz. : 

 Radial, ulnar, and interosseous. The ulnar recurrent comes off immediately above 

 the division of the brachial.

Date of observation, 20th May, 1912.

Sex of subject, Male. 



Side or region of subject, Pancreatic-duodenal region. 



Number of subject, 1. 



Accessory Hepatic Artery arises from the sup. mesenteric A. in such a 

 position as might correspond to a normal pancreatic-duodenal inf. The latter 

 vessel is not found in this case. The main stem passes upwards and outwards 

 over the third portion of the duodenum, the head of the pancreas and its 

 uncinate process and next below the pylorus, passing behind the upper part 

 of the second portion of the duodenum. Gaining the free margin of the 

 lesser omentum, it runs between its folds on the right of the common bile-duct. 

 It reaches the liver substance by piercing the transverse h'ssure to the right 

 of the hepatic duct and in front of the portal vein, and is distributed mainly 

 to the right lobe of liver. 



Branches I. A set of small tortuous vessels passing up over the head of 

 the pancreas to anastomose with the pancreatic branches of 

 the gastro-duodenal. Other small twigs arborise on the 

 first part of duodenum and pylorus. 



II. A set of small branches passing down to anastomose with 

 twigs from the sup. mesenteric on the third and terminal 

 portions of the duodenum. 



III. Right gastro-epiploic arises from it and not from gastro- 

 duod. This reminds us of the termination of the right 

 gastro-epipl. vein in the sup. mesentric vein. 



IV. Cystic branch is given off near its termination and arborises 

 on the sup. surface of the gall-bladder, between it and 

 the liver.
