The ulnar extremity of the arcus venosus dorsalis is some- what less definite than the radial extremity, but is, nevertheless, to be regarded as forming the commencement of the V. basilica, inasmuch as we found this to be the case in 100 7o of the individuals examined by us, whilst further, the ulnar end of the arcus venosus dorsalis, was the main venous outlet in some 53 %• It is thus perfectly evident that the V. basilica is to be regarded as a direct continuation of the ulnar end of the arcus venosus dorsalis. In 47 7o we also found a large well marked vein (see Fig. 2) issuing from the ulnar end of the arcus venosus dorsalis, and passing obliquely proximally and radially across the dorsal surface of the wrist to terminate in the V. cephalica, whilst lastly the V. cephalica accessoria was also found to arise in the ulnar end of the arcus venosus dorsalis in about 28 7o. The pre-Basle description of the radial end of the arch terminating in the "superficial radial vein" we regard as inaccurate, inasmuch as we only found such a termination in 18 7o, ill all the remainder it was in the "median vein", that is, the V, cephalica of the Passing next to the volar sur- face of the palm we found a venous rete best marked on the thenar, hypothenar, and volar aspect of the wrist with its outlet, in 99 % the V. mediana antebrachii. Spalteholz speaks of the plexus passing proximally into the plexus of the forearm, but we only found such an arrangement in 1 7o of our 300 cases. The V. cephalica. The V, cephalica is to be defined as that vein, which commencing in the radial extremity of the arcus venosus dorsalis, winds round the radial border of the forearm, and passes proximally along the arm to the shoulder region.
