Abnormal Hepatic Artery. 



On isolating the contents of Glisson's capsule it was observed that there 

 were two arteries running along the free margin of the gastro-hepatic omen- 

 turn. One of these, the smaller, had the usual origin of the hepatic artery 

 from the coeliac axis, giving off in the neighbourhood of the pylorus the 

 gastro-duodenal artery. The continuation of the artery passed on between 

 the two layers of the gastro-hepatic omentum, and after dividing into two 

 entered the liver at the left extremity of the transverse fissure. 



The abnormal branch arose from the superior mesenteric, and crossing 

 over to the right behind the gastro-duodenal artery and behind the com- 

 mencement of the portal vein ran along between the layers of the gastro- 

 hepatic omentum in close relation with the common bile duct, and after 

 giving oft' a cystic branch to the gall bladder entered the right extremity of 

 the transverse fissure. It was several times larger than the normal artery.

Abnormal Tendon in Arm. 



There are present three abnormalities on the anterior surface of the 

 upper extremity. One of the abnormalities consists of a fibrous tendon 

 coming off the tendinous insertion of the pectoralis major, which running 

 across the anterior surface of the arm in an oblique direction is inserted in 

 the inner condyle of the humerus. In its path this fibrous tendon crosses 

 the middle of the biceps, the brachial artery, the median nerve, the basilic 

 vein and the inner vena comes. 



The second abnormality concerns the position of the median nerve with 

 the brachial artery. In a normal subject the median nerve lies at first to 

 the outside of the brachial vessel and then crosses the latter anteriorily. In 

 this case the median nerve lies to the outside of the brachial artery and 

 then runs obliquely to the brachial artery but on the posterior surface of 

 that artery.
