882 MR. ST. GEORGE MIVART ON THE [ Dee. 6, 
arising from the front of the fibula. On the extensor surface of the 
leg this part is covered by the peroneus, and itself covers the popli- 
teus. 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. On the left side there were two tendons, one bifur- 
cating 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. D*®). This 
muscle has three origins. The first is from the femur, above the 
peroneal condyle, just below the origin of the flexor longus digi- 
torum. The second is from behind the summit of the fibula. The 
third is from behind the fibula lower down, just tibiad of the inser- 
tion 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 digi- 
torum 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.
