fibula. Each of the three tendons running to the digits has a 

 share in both tendons, and the ambiens tendon can be traced 

 splitting up to each. The tendons of the index and of the middle 

 finger are inserted to the base of the first phalanges of their digits. 

 The tendon of the fourth digit is inserted similarly, but in addition 

 has a tendinous slip running to the base of the second digit, taking 

 the place of the absent perforatus and perforans. 



Flexor longus hallucis. — This has two heads — one fleshy from 

 the lower face of the external condyle, with a tendinous slip from 

 the outer side of the intercondylar notch; one tendinous and 

 slight in common with the inner head of the flexor perforatus. 

 The whole muscle is very slender. The tendon passes through 

 the ankle-joint alongside that of the flexor communis, then crosses 

 over that, giving off to it a slip which is thick relatively to the 

 very slender tendon which runs to the base of the first phalanx of 

 the thumb. 



Flexor profundus. — This common deep plantar tendon arises 

 fleshy from the fibula and tibia, halfway down the tibial shaft, and 

 its tendon after receiving slip from the longus hallucis breaks up 

 into a branch, which runs to the base of the claw on digits II., III., 

 and IV. 



Popliteus. — There is only one popliteal running from its fleshy 

 origin from the head of the fibula to a fleshy insertion just under 

 the head of the tibia. 



In the ankle-cartilage the tendons of the perforated and per- 

 forating flexors are most superficial ; the tendon of the perforated 

 muscle of the third digit wraps round that of the fourth. The 

 tendon of the perforatus of the index is more deebly situated, and 

 the tendon of the longus hallucis passes through the cartilage of 

 the extreme outer side. 



Flexor brevis hallucis. — This is stronger than the longus hallucis. 

 It arises from the upper part of the shaft of the tarso-metatarsus 

 on the inner side. It is inserted at the base of the phalanx. 



Flexor brevis hallucis secundus. — This arises from the posterior 

 side of the greater part of the shaft of the tarsus metatarsus and 

 is inserted in common with the last. 



Flexor brevis indicis. — This is a short broad muscle lying in 

 between the diverging ends of the metatarsal shaft, and inserted 

 to the base of phalanx I. 



Adductor annidaris. — This is a large muscle arising from the 

 whole of the metatarsal shaft. 



Extensor hallucis. — A fleshy muscle from the middle quarter of 

 the metatarsal shaft to the middle of the first phalanx. 



Extensor hallucis secundus. — A short entirely muscular slip with 

 origin similar to the last, and insertion to the base of the first 

 phalanx. 



Abductor indicis. — This is a very short muscle from the meta- 

 tarsal shaft to the inner side of the basal phalanx. 



Extensor medii. — This is represented by a rudimentary patch of 

 muscle attached to the fascia covering the base of the first phalanx. 



Adductor annularis. — This long muscle arises down the upper
