one parallel and close to Poupart's ligament (the 

 horizontal series), the other parallel and close to the 

 long saphenous vein (the vertical series). The deep 

 set, about four in number, are placed along the femoral 

 vein, and occupy the crural canal. 



The inguinal glands receive the following lymphatics ; 



Superficial vessels of lower limb vertical set of 

 superficial glands. 



Superficial vessels of lower half of abdomen 

 middle glands, of horizontal set. 



Superficial vessels from outer surface of buttock = 

 external glands of horizontal set. 



From inner surface of buttock = internal glands 

 of horizontal set. (A few of these vessels go to the 

 vertical glands). 



Superficial vessels from external genitals = hori- 

 zontal glands, some few going to vertical set. 



Superficial vessels of perineum vertical set. 



Deep lymphatics of lower limb = deep set of glands. 



The lymphatics that accompany the obturator, 

 gluteal, and sciatic arteries, and the deep vessels of 

 the penis, pass to the pelvis and have no concern 

 with the inguinal glands. 



One of the deep glands lies in the crural canal 

 and upon the septum crurale. Being surrounded by 

 dense structures, it is apt to cause great distress when 

 inflamed, and great pain when the hip is moved. In 

 some cases, by reflex disturbance, it has produced 

 symptoms akin to those of strangulated hernia. Some 

 branches of the anterior crural nerve lie over the 

 " inguinal lymph glands, and Sir B. Brodie reports a case 

 in which these branches were stretched over two en- 

 larged glands, like strings of a violin over its bridge, 

 so that violent pain and convulsive movements were 

 set lip in the limb. 



Elephantiasis Arabum is more common in the 

 lower limb than in any other part, and leads to an
