inferior, quadratus femoris, and the adductor magnus muscles; while it is covered in, first by the gluteus maximus, then for a space by the biceps, and all along by the semi-tendinosus and semi-membranosus. The first branches from it supply the ex- ternal condyle of the femur, and after this they pass on down to be distributed to the fibrous capsule, and to the synovial membrane of the outer side of the knee-joint. The lesser ischiatic nerve passes out of the pelvis through the great sacro-ischiatic foramen also, and near by the side of the great sciatic nerve. These more local and superficial nerves curve their branches both backward and for- ward, to be distributed in the neighborhood of the hip. It first supplies the gluteus maximus even to its upper border under the crest of the ilium, while other branches turn backwards about the coccyx, and others go still farther down on the back of the thigh and leg. The middle posterior cutaneous nerve is one branch of it, and curves around and over the tuber- osity of the ischium in company with the scro- tal branch, then passes downwards superficially along the middle posterior aspect of the thigh, to be distributed to the integument along in the popliteal region both to the sides and hack of the bend of the knee, and down as far as the middle of the calf of the leg. hfa. The popliteal nerve is the "continuation" of the great ischiatic, from that point where the ischiatic (sciatic) nerve divides, to the arch of the soleus, from whence, it is then called the the Popliteal Nerve, posterior tibial nerve.
