annular ligament, to be lost on the skin of the palm of the hand, and over the ball of the thumb. As the principal branch of the median nerve reaches the palm of the hand, I should have said, it spreads out flattened, and divides there into six branches — one muscular and five digital. The muscular branch goes to the ball of the thumb. The digital branches first send twigs to the lumbricales muscles, and then become thus distributed: two pass outward to supply the palmar sides or edges of the thumb; one goes to the radial side of the index or fore finger; one other divides into four, two of which go to supply the neighboring sides of the index and mid- dle fingers; while the other two go to supply the neighboring sides of the mid- dle and ring fingers; so that the outer side of the ring finger, together with the little finger, goes unsupplied from this source. As the digital nerves course along the inner lateral side or edge of the fingers, when opposite the base of the first phalanx each nerve gives off a dorsal branch, which runs along the border of the dorsum of the fingers. Then, very near the extremity of the finger, each digital nerve divides again into two, — a final palmar and a dorsal branch,—the former supplying the senti- ent fibres for the pulpy integuments of the balls and tips of the fingers, while the latter supplies the root of the nail, and the Nerves structures around and beneath it. No on the Front of the Forearm. 1. The Median Nerve. 2. Anterior Branch of the Musculo-Spi- ral, or Radial Nerve. 3. The Ulnar Nerve. 4. Division of the Median Nerve in the Palm to the Thumh, First, Sec- ond, and Radial Side of the Third Fingers. 5. Division of the Ulnar Nerve to the Ulnar Side of the Third, and to both sides of the Fourth Fingers.
