Galera it is inserted very high up in front of pectineus and down as 
far as the middle third of the thigh. 
Qnadratus fenioris is very large and normal, 0*07. Gastrocnemius 
externus has a fabella, and is almost separate from the plantaris, the 
gastrocnemius internus has a fabella in Yiverra, butnone in Galera. The 
plantaris arises from the external fabella, and from the condyle above it, 
andishere onlyslightly joined to the gastrocnemius externus muscle, its 
tendon passes that of the gastrocnemius and is inserted into the plantar 
fascia. 
The sole us is quite separate, arising from the head of the fibula 
and is inserted into the upper part of the os calcis. 
The popliteus has a cartilaginous fabella, and is attached to one- 
third of the back of the tibia. 
Tibialis anticus is large, single, and inserted into the metatarsal 
bone of the hallux. 
Extensor digitorum communis is large, tendinous and femoral in 
its origin as usual, and inserted by four tendons into the four outer 
digits, the belly divides into two parts, of which one goes to the 
second, third, and half of the fourth digit, the other to half of the 
fourth and fifth, the two slips to the fourth unite on the dorsum of 
the foot. 
Extensor hallucis proprius is slender, and arises from the upper 
half of the margin of the fibula, and is inserted solely into the hallux. 
Peroneus longus sends a tendon to the posterior part of the floor of 
its own groove in the os calcis, and is inserted into the fifth and first 
metatarsal bones. 
Peroneus brevis is normal, and peroneus quinti is as usual, and 
quite separate in both. 
Tibialis posticus is fleshy, and mostly fibular and membranous in 
origin, it is inserted into the scaphoid bone ; in Galera it arises only 
from the heads of fibula and tibia. 
The flexor longus digitorum is as usual tibial, and the flexor 
hallucis fibular and much larger; the two tendons unite, and are 
inserted into the five toes ; there is a strong accessorius from the outer 
side of the calcaneum, and three lumbricales, none existing for the 
index. 
The muscles of the sole are flexor brevis hallucis from the entocu- 
neiform to the outer sesamoid, flexor brevis digitorum from the plan- 
taris tendon to the three middle toes, there is a perforated tendon for 
the little toe, but it does not arise from this muscle, and is only con - 
nected to the plantar fascia. 
Adductor hallucis is calcaneo-halluceal, adductor is from the 
meso- cuneiform, abductor and flexor brevis minimi digiti are as 
usual. 
The interossei muscles are as follows : — 
First plantar, an adductor indicis. 
Second plantar an adductor annularis. 
Third plantar, an adductor minimi digiti.
