ileum. It is inferted into a cavity at the root of the 

 trochanter major. By its contraction it moves the 

 thigh a little upwards, and rolls it outwards. 



The gemini confifts of two portions, one of which 

 rifes from the outer furface of the fpine of the os if- 

 chium, tfre other from the tuberofity of the os ifchium 

 and pofterior facro-ifchiatic ligament. It is inferted 

 into the fame part of the trochanter major with the 

 pyriformis and obturator internus. This mufcle rolls 

 the thigh outwards, and confines the tendon of the ob- 

 turator internus.' 



The quadratus femoris arifes from the outfide of the 

 tuberofity of the os ifchium, is inferted ! into a ridge 

 which pafles from one trochanter to the other, and rolls 

 the thigh outwards. 



The mufcles feated on the thigh, and which move 

 the leg, confift of two on the infide, one on the outfide, 

 four before, and four behind. 



On the infide are, 



The fartorius, which arifes from the fuperior an- 

 terior fpinous procefs of the ileum* This long mufcle, 

 running downwards and a little inwards, is inferted 

 into the inner fide of the tibia. It draws the legs 

 obliquely inwards, fo as to bring the legs acrofs each 

 other, for which reafon it is called the fartorius, or the 

 taylor's mufcle. 



The gracilis arifes near the fymphyfis of the ofTa 

 pubis, and is inferted with the fartorius into the inner 

 part of the tibia. It afilfts the fortorius in bringing 

 the legs acrofs, and, when they are a little bent, to 

 concur in bending them further. 



On the outfide of the thigh is placed 



The tenfor vaginas femoris, which arifes from the 



external part of the anterior fuperior fpinous procels of 



the os ileum, It is inferted into the tendinous fafcia
