 mediastinal vein ending at beyond half of the length ; radial vein end- 

 ing at much beyond five-sixths of the length ; cubital vein ending near 

 the tip of the costal ; praebrachial vein forming a slightly acute angle at 

 the flexure, much curved inward near this, straight from thence to the
