Nervous and mental diseases . ot, par-ticularly at the ball of the great toe, are likely to develop. The external division of the sciatic, the e^itemal popliteal or peronealnerve, occupies an exposed position (1) in the ham and (2) below theknee on the outside of the neck of the fibula.

The muscular fullness on the anterior and outeraspect of the leg is lost; the uncovered crest of the tibia is extremely prom-inent. A tendency to equinovarus is produced that is often rendered apermanent deformity by contracture in the calf-muscles. The outerhalf of the front of the leg and the dorsum of the foot are anesthetic. The inner division of the sciatic, the internal popliteal, is analogousto the median and ulnar in the upper extremity. It supplies all thecalf-muscles, the long flexors of the toes, and all the small muscles of. Fig. ns.—Paralysis of anterior crural; wasting ofright thigh. .1
