anterior or femoral nerve springs mostly from the lumbar plexus, we will review this first. This nerve is the largest branch from the lumbar plexus ; it emerges beneath Poupart's ligament into the thigh, just above the groin, where it is flattened, but imme- diately subdivides into a great number of branches, almost all of which are superficial. Of its first branches are the cutaneous nerves, two in number, which, after perforating the sar- torius muscle, and there giving filaments, pierce the fascia lata,, and are then dis- tributed to the integuments of the ante- rior inner aspect of the thigh, over its middle and lower part, even down to the inner side of the knee. The most super- ficial branch is the perforans, that comes out of the upper part of the sartorius, and there communicates with the genito-crural nerve, then divides into many branches, which supply the surface of the anterior and outer aspect of the limb as far as the patella. Another branch comes out of the fascia lata at the lower third of the thigh, and descends over the inner condyle of the knee joint, and curves for- ward around to the front of the knee, terminating just below the patella. Be- sides these, there is an important surface branch, derived from the muscular branch that supplies the vastus externus muscle, which is found radiated to the integ- uments over the outer side of the lower rte- ti- a view of the ,...„,. ,,., m, , , i FemoroCrural Nerve, show- third ot the thigh.
