78 PROCEEDINGS OF THE ANATOMICAL AND ANTHROPOLOGICAL 



The slip is 2 inches long and f of an inch broad at its origin and 

 tapers to its insertion. It is flattened against the sheath of the vessels 

 and nerves, which lie external to it. Its upper border is about an 

 inch below the posterior circumflex and subscapular arteries. Its 

 inferior border is the same distance above the floor of the axilla. This 

 arch occurs in about seven subjects in 100, and is often inserted into 

 the pectoralis major or the fascia over the biceps.

Liver with Riedel's lobe. 



The right lobe of this liver is enlarged in its vertical extent, 

 measuring 8 inches in this direction. On the anterior surface of this 

 lobe there is a deep transverse groove about f of an inch above the 

 level of fundus of gall bladder.

Abnormal arrangement of arteries of arm and forearm (left). 



The ulnar artery originates about two inches below the commence- 

 ment of the brachial artery. It is in close relation with the brachial 

 artery, being separated from it only by the ulnar nerve. At the elbow 

 it crosses the brachial artery and becomes closely attached to the flexor 

 carpi radialis which had to be slightly cut to expose the artery. For 

 the rest of its course it is superficial to the flexor group of muscles 

 after emerging from the fibres of the flexor carpi radialis, passing 

 downwards and inwards to come into close relation with the ulnar 

 nerve at the pisiform bone. At its origin it is quite a quarter of an 

 inch in diameter and its upper part gives muscular branches to the 

 biceps and to the flexor carpi radialis. Its lower part gives off no 

 branches. 



In this forearm, too, the brachial artery at about an inch below
