 medial cutaneous branch of the femoral nerve. The saphenous nerve, 

 accompanied by the ramus saphenus of the arteria gemi siiprema^ will be 

 found under cover of the sartorius. They afterwards come to the surface 

 at its posterior border. The great saphenous vein ascends on the surface

 of the thigh (O.T. internal ctitaneous] courses distally along the posterior 

 border of the same muscle, and comes, to the surface a short distance 

 posterior to the saphenous nerve. Properly speaking, these structures 

 belong to the thigh and they have already been seen in the dissection of 

 its medial region (p. 198). When the boundaries of the fossa are thoroughly
