The flexor accessorius was well developed, and arose from 

 the under surface of the calcaneum, and, passing obliquely in- 

 wards across the plantar aspect of the tendon of the common 

 flexor, was inserted into it just posterior to its division into 

 digital slips. 



The peronei were three in number. They all arose from the 

 upper part of the fibula ; and their tendons passed through a 

 strong ligamentous pulley stretched between the external mal- 

 leolus and the calcaneum. 



The most anterior at origin (peroneus longus) took origin in 

 close company with the origin of the long extensor of the toes. 

 Its tendon lay outermost of the peroneal tendons, under the 

 ligamentous band, soon after leaving which it passed under a 

 second pulley situated on the fore part of the calcaneum, and, 

 running along the fibular side of the foot, passed into the sole 

 along the plantar aspect of the cuboid bone, and was finally 

 inserted into the fibular side of the scaphoid, on its plantar 

 aspect. This muscle was separated from the other peronei, at 

 origin, by the peroneal vessels and nerve. Its tendon did not 

 send any oftset to the fifth digit. 



The two other peronei were fused into one muscle ; but in the 

 ligamentous pulley the compound tendon divided into two un- 

 equal slips, the smaller of which passed to the side of the base 

 of the proximal phalanx of the fifth digit (peroneus tertius or 

 quinti digiti'?). The other, and by far the largest, slip termi- 

 nated at a tubercle on the base of the fifth metacarpal, broad- 

 ening out at its insertion (peroneus brevis). 



The tibialis anticus, a very well-developed muscle, arose 

 from the upper half of the tibia and from the middle third of 

 the fibula. Its very strong single tendon passed under the com- 

 mon annular ligament, to be inserted into the posterior and 

 inferior process of the ento-cuneiform bone, covering at inser- 

 tion a transverse ligament passing from this bone to the base 

 of the strigil bone. 



Meckel (Vergleich. Anat. p. 624) describes this muscle as 

 having two heads of origin, but states that the tendon termi- 

 nates at the rudimentary hallux. 



The extensor communis digitorum arose from the head of 

 the fibula, in company with the peroneus longus, and from 

 the adjacent part of the tibia. Its tendons passed under the 

 broad, common (annular) ligament, and then under a very 

 strong ligamentous bridge (proper to it alone) which is fastened 

 to a process from the anterior part of the astragalus. On the 

 dorsum of the foot it exjDanded into a web which was fastened 

 to the bases of the proximal phalanges of the toes, including 

 the rudimentary hallux, and was also, except in the case of
