'" Tlie rečius arises by ajascia frora the spinous processes of tlie 

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

 lovver halfof the external part of the dorsum ilii and sacro-iliac sym- 

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

 into the lovver edge of the groove on the anterior part of ihe patella. 

 The tensor vagina Jemoris arises by afoscia from the sacral vertebrcB, 

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

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

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

 inserted into ihe fascia of the thigh about halfvvay dovvn. 'Y\\e glu- 

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

 tends betvveen 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 vvhich joins it. The glutaus minimus arises from 

 the whole of the dorsum ilii unoccupied by the other glutaei except 

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

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

 os ilium belovv the acetabulum ; it passes on the posterior surface of 

 the thigh-bone ; and when it has passed belovv 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 obliąuely 

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

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

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

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

 belovv its head. Another musele arises from the anterior part of the 

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

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

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

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

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

 the tibia jūst belovv the tubercle. The semitendinosus arises from 

 the ridge immediately anterior to the glutceus 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 musele arises from the ischium anterior to the 

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

 belovv ihe pyriformis . Of the triceps adductorjemoris 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 interosseousligament vvhich unites t\\epubisaxičiischium: 

 theyjoin on theupper third ofthe thigh, and are attached to i\\Q linea 

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

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

 Jbramen, and from the ischium ; it forms a tendon vvhich passes through 

 the thyroid ybra/ne«, is tied dovvn to the joint, and is inserted into 

 the anterior part of the great trochanter, A musele arises from tho
