Haller says, " Hzec brachii vasa aliquando in vene sections pertusa, molestissima et diuturna lympha: prolluvia faeiunt, quale et ipse vidi." I have never seen any such flow of lymph from bleeding in the arm. When students of anatomy have happened to wound themselves, in dissecting the dead body, either on the little or ring finger, the red lines, which appeared in consequence of this, constantly took the course I have now mentioned. Mr. Hewson appears to have been less successful in his discoveries here than in the lower extremity,- which may account for lIal- ler's expression, " tenuis notitia." I have injected other absorbents, arising also from the palm of the hand, on the side towards the thumb, which ran on both sides of the flexor pahnaris muscle, and, at the bending of tliejoint between the arm and fore-arm, joined the plexus last described, but did not pass into any glands till they came to the axilla.

The superficial run with the cutaneous form two great deep-seated accompany the arteries. The cutaneous veins I have injected these with quicksilver, in the human subject, inside. There are other absorbents on the back of the hand, on the side next the little finger, which turning round with the ulnaris externzi, are inserted at last into a gland almost constantly to be found upon the anterior surface of the inner eontlyle of the humerus: from this gland a very large vas cf. fercns goes out, which almost immediately joins the bi'achial artery, and then splitting into two, accompanies it all the way to the axilla; and its to branches trunks in the arm; of these the basilic is the principal.
