Show 882 MR. ST. GEORGE MIVART ON THE [Dec. 6, arising from tbe front of the fibula. On the extensor surface of the leg this part is covered by the peroncus, and itself covers the popliteus. The muscle also takes origin from the tibial aspect of the fibula, from its summit down to the origin of the tibialis posticus. Passing downward it ended in the right foot of the specimen in a delicate tendon, which bifurcated for the first and second digits, and also gave off a very delicate tendon joining the long flexor tendon of the third digit. O n the left side there were two tendons, one bifurcating for the first and second digits, the other dividing into three for the three tibial digits. Flexor tertius digitorum (figs. 17, 20, 23, 24, & 29, F. D2). This muscle has three origins. The first is from the femur, above the peroneal condyle, just below the origin of the flexor longus digitorum. The second is from behind the summit of the fibula. The third is from behind the fibula lower down, just tibiad of the insertion of the ilio-peroneal. Suddenly contracting (like the flexor longus digitorum), it ends in a delicate tendon, which gives off two very delicate slips, one joining that tendon of the flexor longus digitorum which goes to the third digit, the other joining that tendon of the flexor longus which goes to the fourth digit. The tendon then continues on as the long flexor tendon of the fifth digit. Fig. 25. Front view of right leg. El & E2, Ee & E\ Es, E\ Extensores metatarsorum. F. H. Flexor hallucis. P. Peroneus. T. A.
