the internal malleolus. The tubercle of the scaphoid is one 

 and one-fourth of an inch in front of the same point. On 

 the outer side of the foot the os calcis, cuboid, and base of 

 the fifth metatarsal bones can be felt. 



DISSECTION. 



Incision. (i) From the middle of Poupart's ligament down the front of 

 the thigh to below the patella. 



(2) Two short transverse cuts at the lower end of (i). 

 Remove the skin only, turning it off laterally as far as possible. 



The Superficial Fascia. Fig. 115. 



This fascia varies in thickness with the amount of adipose 

 tissue present. It is described as consisting of two layers, 

 the superficial and deep, but this distinction can be readily 

 made only in the upper third of the thigh. Within the 

 superficial fascia are contained the superficial vessels, nerves, 

 and lymphatics. 



The superficial layer of the fascia passes up over Pou- 

 part's ligament to become continuous with a similar layer of 

 the abdomen, behind with the fascia of the buttocks, and 

 below passes into that covering the leg. 



The deep layer is only demonstrated with ease in the 

 upper third of the thigh. It consists of a thickening of 

 the under surface of the superficial fascia and is attached 

 above to the crest of the ilium, Poupart's ligament, spine, 

 crest, and front of the pubes ; internally and externally it 

 blends with the fascia lata, centrally it covers over the 

 saphenous opening and is strongly attached to its outer and 

 lower margins and loosely to its inner margin, forming the 

 cribriform fascia. 



DISSECTION. 



Trace the superficial arteries, veins, and nerves. Locate the femoral lym- 

 phatics.
