seat of all sciatic tenderness and pains. Next, we find a neu- ralgic point over the course of the middle posterior cutaneous nerve trunk, and also in the popliteal space where it is dis- tributed ; a neuralgic spot at the external condyle of the femur; a neuralgic spot over the course of the popliteal nerve, and another at its termination. Another neuralgic spot is found over the superficial trunk of the external saphenous nerve, on the middle calf of the leg, and along the outer border of the tendo-Achillis, and at the root of the little toe. Another neu- ralgic spot is some two inches below the knee joint, on the outer aspect of the leg, where the peroneal nerve I rank emerges to become superficial; and another spot at the outer ankle joint and heel, where it terminates. And finally, we find a neuralgic (and gouty ?) spot at the terminal twigs of the great sciatic nerve, through the anterior tibial, which we know is mostly on the big toe. Now, if we examine the anterior aspect of the lower limb, we find the first and most frequently neuralgic sj/ot imme- diately under PouparCs ligament, lOhere the femoral nerve trunk emerges, and there becomes superficial. So, indeed, is all the anterior and inner part of the thigh very prone to neuralgic pains, because the femoral or sacral nerve is superficial, and throws nearly all its ultimate ramification of nervelcts into the integument over this space from the groin to below the knee, but particularly over the inner condyle of the knee, over the middle of the sartorius and rectus femoris muscles, also just below the knee-pan. Next, we often find a neuralgic spot over the exit of the short saphenous nerve, along the inner border of the sartorius muscle ; then again over the long saphenous nerve, but more particularly at its termination along the inner ankle, and about the inner side of the great joint of the big toe. And finally, we find liable to neuralgia the spot of emergence of the cutaneous branch of the internal saphenous nerve, which is about the middle of the thigh, and where many other nerves also become superficial; and another spot might be mentioned, and that is, the ankle joint. This may be doubted by some, as pahis here are usually referred to sprain or rheumatism;
