of the thumb, (2) tributaries from the volar and dorsal aspects 

 of the forearm, (3) tributaries from the lateral and dorsal 

 aspects of the arm, (4) a tributary from the side of the shoulder, 

 and (5), immediately before it pierces the costo-coracoid 

 membrane, it is joined by the venae comites of the deltoid and 

 acromial branches of the thoraco-acromial artery. It is 

 accompanied by lymph vessels from the dorsum of the hand, 

 and the lateral and dorsal sides of the forearm and arm ; 

 those vessels terminate in the delto-pectoral lymph glands. 



Vena Basilica. The basilic vein commences at the ulnar 

 end of the dorsal venous arch of the hand. It receives the 

 dorsal digital vein from the ulnar side of the little finger and 

 then ascends on the ulnar part of the dorsal surface of the 

 forearm. Below the elbow it turns round the ulnar border 

 of the forearm and ascends to the groove along the medial 

 border of the biceps brachii. About 30 mm. above the 

 medial epicondyle it is joined by the median cubital vein, 

 then it continues proximally to the level of the middle of the 

 arm, where it pierces the deep fascia. After it has pierced 

 the deep fascia, it runs along the medial side of the brachial 

 artery to the lower border of the teres major, where it becomes 

 the axillary vein ; only the termination of this part of the 

 vein can be seen at present, the remainder will be dis- 

 played in a later dissection. The tributaries of the basilic 

 vein are (i) the ulnar dorsal digital vein of the little finger, 

 (2) tributaries from the volar and dorsal aspects of the fore- 

 arm, (3) the median cubital vein, (4) tributaries from the 

 medial and posterior parts of the arm. It is accompanied 

 by lymph vessels from the dorsum and palm of the hand 

 and the volar and dorsal aspects of the forearm. Some 

 of the accompanying lymph vessels end in the superficial 

 cubital glands, which lie proximal to the medial epicondyle. 

 Others pass directly to the brachial and the lateral axillary 

 glands. 



Vena Mediana Cubiti. The median cubital vein is a 

 large communicating vein which springs from the cephalic 

 vein about 25 mm. below the bend of the elbow, and 

 terminates in the basilic vein 30 mm. above the medial 

 epicondyle. As it crosses from the cephalic to the basilic 

 vein it receives tributaries from the volar aspect of the 

 forearm, it is separated from the distal part of the brachial 

 artery by a thickened portion of deep fascia called the
