    The psoadiliacus has an extensive insertion, tlie iliae portion being prolonged for some distanee on the shaft of the femur. The psoas factor is chiefly inserted into the lesser trochanter. The iliac portion is separated from the psoas parvus, just be- fore the latter becomes tendinous, by a nerve (the external cutaneous?). A few fibres from its external edge are pro- longed on to the rectus femoris, and blend with it. The psoas parvus (which is not represented in Cuvier’s plates) is inserted by a strong shining tendon into a small and sharp tubercle lying in advance of the root of the slightly convex inner face of the ilium and the junction of the os pubis with this bone. As the animal was so well ribbed home,” to use a veteri- nary expression, I could not examine the origins of the psoas parvus and psoadiliacus, a perfect skeleton being required for the museum of the College of Surgeons. The pectineus, a well-developed, fan-shaped muscle, arose from the superior edge of the iliac portion of the pubis, covered by the highest fibres of origin of the gracilis, and had a fleshy insertion into the inner side of the femur from below the lesser trochanter to a point just above.the inner condyle. The adductors seemed to be represented by two muscles. 1. arose from the rest of the anterior ramus of the os pubis, in advance of the pectineus, as far as the symphysis. It soon split into two slips, one of which was inserted tendinously 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 inner 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 widens 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 surface of the femur. 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 surface of the bone. Part of its tenninal tendon appeared to be prolonged upwards to tlic patella. A like inward dis])laccnient of tlic sartorius
