    Abductor minimi digiti arises from the annular ligament and pisiform bone. It is inserted into the sesamoid bone of the 5th digit to the ulnar side of flexor brevis digitorum. C. and L.—283, fig. 2; 284, figs. 2, 3, 4 (v). In 283, fig. 2, a small muscle (“abductor”—adductor?—“minimi digiti”) is shown internal to the short flexor of the toes. We have not found this. The palmar fascia consists of strong fibrous bands crossing in various directions, with large intermediate spaces filled with fat, especially between the digits. An exceedingly strong semi- circular band, concave towards the wrist, stretches across the heads of the metacarpal bones, and forms sheaths in the usual way for the flexor tendons. By dissection these sheaths can be resolved into a superficial or proper transverse ligament, and a deeper layer, which, when divided, presents on its deep surface two tendinous slips passing to be inserted into the base of the second phalanx on each side of the flexor tendon. This dis- position resembles the ordinary arrangement of the flexor sublimis. C. and L., 284, fig. 3. Lumbricales arise all together from the superficial surface of the flexor tendon, just above its division. They are four in number, of which the 1st and 2d (from the radial side) are respectively inserted into the bases of the 1st and 2d digits on the ulnar side. The 3d lumbrical is inserted into the deep side of the sheath of the flexor of the 3d digit, and is continuous with one of the lateral tendinous bands of the flexor sheath. The 4th lumbrical passes deeply between the 3d and 4th digits, and is connected with an aponeurosis from the extensor tendon. The 1st and 2d lumbricales appear to have a similar attachment on the extensor side of the manus. C. and L.—284, fig. 4. The 1st lumbrical is not seen in this drawing. Flexor brevis pollicis.—The only short muscle of the first digit. Arises by a pointed origin from the os magnum, and is inserted into the sesamoid bone on the head of the first metacarpal. This muscle corresponds most nearly with the inner head of flexor brevis pollicis. Not in C. and L. Flexor brevis minimi digiti consists of two slips, which arise
