'" The rectus arises by ajascia from tlie spinous processes of the 

 last three dorsal and two lumbar vertebrce, and muscular from the 

 lower half of the external part oi the dorsum z7?7andsacro-iliac «/>«- 

 physis; and, passing over the neck of the thigh-bone, is inserted 

 into the lower edge of the groove on the anterior part of the patella. 

 The tensor vagincejemoris arises by afoscia from the sacral vertehrcE, 

 passes over the cotyloid cavity and trochanter major, and turning to the 

 anterior part of the thigh is joined by another bead which arises im- 

 mediately anterior to the cotyloid cavity ; after this union they are 

 inserted into the Jascia of the thigh about halfway down. The gtu- 

 taus medius at its origin occupies that part of the dorsum which ex- 

 tends between the origin of the acetabulum and the ridge situated in 

 the centre, and passes downwards and is inserted into the trochanter 

 minor and the ridge which joins it. The glutaus minimus arises from 

 the whole of the dorsum ilii unoccupied by the other glut cd except 

 its crista, and is inserted into the anterior part of the trochanter 

 major. The glutaus maximus arises from the prominent ridge on the 

 OS ilium below the acetabulum; it passes on the posterior surface of 

 the thigh-bone; and when it has passed below the head of the tibia 

 it forms a round tendon and passes through a loop situated on the 

 external posterior part of the tibia ; continuing its course obliquely 

 downwards, it is inserted into the scabrous ridge on the posterior 

 surface of the tibia near its head. A muscle arises from the trans- 

 verse processes of all the caudal vertebrce except the last, goes for- 

 wards, and is attached to the postero-internal edge of the tibia just 

 below its head. Another muscle arises from the anterior part of the 

 last caudal veiiebrce, and is inserted into the external part of the 

 linea aspera after its bifurcation. The piriformis arises from the an- 

 terior oblique processes of the caudal vertebra, from the tip of the 

 ischium, and from the internal part of the os pubis ; the fibres con- 

 verge downwards, and are inserted into the intero-anterior ridge of 

 the tibia iust below the tubercle. The semitendinosus arises from 

 the ridge immediately anterior to the glut eeus maximus, and is inserted 

 immediately inferior to the bifurcation of the linea aspera on its ex- 

 ternal division. The gemini arise from the ischium immediately pos- 

 terior to its spine, and are inserted into the cavity posterior to the 

 trochanter major. A muscle arises from the ischium anterior to the 

 gemini, and is inserted into the intero-anterior ridge of the tibia, just 

 below the pyriformis. Of the triceps adductor femor is the first head 

 arises from the extero-inferior part of the pubis; the second head 

 arises immediately above the first ; and the third above the second, 

 and from the interosseous ligament which unites thepubis and ischium: 

 they join on the upper third of the thigh, and are attached to the linea 

 aspera on its internal side and division. The obturator internus arises 

 fleshy from the internal part of the jmbis, from part of the obturator 

 foramen, and from the ischium; it forms a tendon which passes through 

 the thyroid Jbramen, is tied down to the joint, and is inserted into 

 the anterior part of the great trochanter. A muscle arises from tho
