in advance of the pcctincus, as fur as the symphysis. It soon 

 split into two slips, one of which was inserted tendinonsly 

 into the lower surface of the femur, slightly in advance of the 

 insertion of the pectineus^ while the other terminated (partly 

 fleshy, partly tendinous) at the iinier condyle, above and 

 covering the insertion of the superior factor of the semitendi- 

 nosus. 



2. took origin from the same portion of the pubic bone as 

 the preceding, lying between it and part of the origin of the 

 gracilis. It Avidens out gradually toward the insertion, which 

 is into nearly the whole length of the outer part of the inferior 

 surface of the femur, being coextensive with the origin of the 

 femoral portion of the biceps. 



A small muscle arising from the pubis, below the lowest 

 fibres of origin of the pectineus, was inserted into the inter- 

 trochanteric space on the inferior sm'face of the femm*. 



The quadriceps extensor did not present any peculiarities 

 worthy of note. 



The sartorius arose from strong fascia attached to the tendon 

 of the psoas parvus, and from Poupart's ligament, and was 

 inserted, above and slightly external to the gracilis, into the 

 tibia, close to the boundary of the articular sm-face of the bone. 

 Part of its terminal tendon appeared to be prolonged upwards 

 to the patella. A like inward displacement of the sartorius 

 from its usual origin has been described by Meckel (Vergleich. 

 Anat. iii. p. 614) and Prof, Macalister {lor. ci't. p. 64) as taking- 

 place in the A'i, by Krause* in the liabbit, by Prof. Hyrtl in 

 the Chlamydophore t, and by myself (Trans. Linn. Soc. 

 vol. xxvi. pp. 553, 592) in Dasypus and Orycteropus. 



The gracilis has a <-sliaped origin (left side) from the edge 

 of the OS pubis, and for about two-thirds of the ischio-pubic 

 bone, and is inserted by a broad tendon into the up[)er third of 

 the inner edge of the tibia, the upper terminal fibres covering 

 the strong internal lateral ligament. 



The semitendinosus took origin in two slips from the tuber 

 ischii. 



1. The superior, which vras fused witli the biceps at origin, 

 was inserted into the posterior part of the inner condyle of the 

 femur, just below the insertion of the adductor, and posterior 

 to the internal lateral ligament. 



2. The inferior rises just below the former, covered by the 

 most inferior fibres of origin of the gluteus maximus, and joins
