This large muscle takes its origin almost exclusively from the glu- 

 teal fascia flowing over the great trochanter, and has only a few fibres 

 arising from the side of the femur ; and some fibres of the piriformis 



border.

This muscle has the usual origin, but is inserted subcentrally into 

 the patella, rather on the inner side ; it bears a close resemblance to one 

 of the sartorii in the Dog.

This muscle arises from the tuber ischii, as usual, with a few fibres, 

 forming the posterior border of the gl. max. from the first caudal ver- 

 tebra ; and is inserted by a tendon, 1 \ in. to 2^ in. long, into the upper 

 third of tibia, by fascia common to it and to gracilis.

 The biceps is blended, near its origin, with some fibres of the semi- 

 tendinosus, and is inserted into the fascia of the thigh immediately below
