system at the elbow. On the mesal aspect of the biceps it divides 

 into three or four vessels which freely anastomose with each other as 

 they continue along side of the brachial artery to their termination 

 in the single axillary gland. This lies on the mesal surface of the 

 distal end of the teres major muscle. From this gland usually only 

 one vessel leads the lymph to the tracheal trunk near where the latter 

 flows into the jugular vein. 



This system receives the lymph from the muscles and bones of 

 the entire limb except part of the foot. Most of the lymph from the 

 shoulder muscles enters the axillary gland, only a small part passing 

 to the cervical glands. 



Lymph System of the Pelvic Limb. 



The naain trunks of the superficial system arrange themselves in 

 two groups. One group composed usually of two vessels arises from 

 the dorsal aspect of the foot, turns to the outer side of the leg in 

 the distal region of the crus, whence it proceeds to the popliteal 

 gland lying in a bed of fat between the biceps femoris and semitend- 

 inosus muscles. From this gland, a single large vessel accompanying 

 the small saphenous vein, leads direct to the gluteal gland imbedded 

 in the fat mass lying at the root of the tail. The other group com- 

 posed of two or three vessels arising from the plantar portion of the 

 foot, accompanies the great saphenous vein to its junction with the 

 femoral vein along which it continues to the lumbar glands lying on 

 the lateral aspect of the origin of the femoral artery. 



Several quite large subcutaneous vessels lead the lymph from 

 the skin of the thigh to the large paired inguinal gland situated in 

 the fat mass of the inguinal region. Reighard and Jennings have 

 erred I think in stating that the inguinal glands are either very 

 small or not present in the cat as I have in all cases found two of 

 more than a centimetre in length. 



The superficial system of this limb collects the lymph from the 

 foot and from the skin of the entire limb. 



I found much difficulty in injecting the deep system of the pelvic 

 limb, although the largest vessel is nearly a millimetre in diameter. 

 Others have endeavored to demonstrate this system without much 

 success as may be seen by the following statement from Reighard 

 and Jennings ^) : "The pelvic limbs have perhaps a deep system of 

 lymphatics, accompanying the deep veins; if so they are not easily 

 demonstrable."
