 ending very near the tip of the costal ; praBbrachial vein forming an 

 obtuse angle at the flexure, very slightly curved inward from thence to

 of the length ; mediastinal vein ending before half the length ; radial 

 vein ending at a little beyond three-fourths of the length ; cubital vein 

 joining the costal near its tip ; praBbrachial vein forming an obtuse 

 angle at its flexure, near which it is slightly curved inward, and is
