The rightthigh, four inches above pa-tella, 11 inches ; left thigh,10*^ inches. Right calf, atgreatest circumference, 8inches ; left calf, 8^ boy walks with a slightlywaddling gait and has greatdifficulty in climbing thestairs. He can raise toes slight-ly on the left side, less wellon the right side. Can raiseleft leg on tiptoe, but cannotdo this with the right leg. Inattempting to raise the wholebody on tiptoe, falls : Tactile sensationnormal as determined by cot-ton, pin test, and the writingof numbers on the skin. Tem-perature sense normal. Painsense exaggerated. Muscu-lar sense normal. Plantar re-flexes present and knee-jerk about normal. Slight lividityof legs, not so marked, however, as in the case of Fig. 85.(Same patient as in Fig. 86.) The electrical examination : In the upper extremities the faradic responsein the median and ulnar nerves was decidedly diminished. In the mediannerve first KCC with 13 MA; ACC not at 20 MA. Galvanic current: Inthe right leg no reactions could be obtained by excitation of the nerves withcurrents used. In the extensor hallucis longus the first KCC and ACC were PROGRESSIVE MUSCULAR ATROPHIES. 363 obtained with a current of 14 MA. The tibialis anticus did not respond tocurrents of 20 MA. The anterior thigh muscles and posterior thigh musclesrespond to strong currents of 16 MA, without reversal of formula. In theleft leg, the extensor hallucis, first KCC with 16 MA ; first ACC with 18MA. No contractions could be obtained by direct excitation of the tibialisanticus, with currents up to 20 MA; on excitation of the extensor digitorumcommunis there is a slight movementof the sma
