jjart vvitli the other adductors is peculiar. Wilder found the pectlnem and three 

 adductors 25i"esent Init more intiniatel_y connected than in man. 



The anterior muscles of the leg, \\m peronel, those of the calf, present nothing note- 

 worthy. The plantaris is present and distinct, going partly to the tendo Achillis and 

 partly to the fascia at the inner side of the ankle. This muscle seems to be at least as 

 often wanting as present. An insertion much like tlie present one is described by 

 Humphry. 



Peroneus'longu-^ and hreoh are inserted respectively to the base of the first and 

 of the fifth metatarsals. Neither has an}' further insertion. 



Extensor hrevls is remarkable oidy for the fact that the first division sends an 

 additional insertion to the second phalanx of the great toe. 



The tibial and fibular flexors {flexor longus and flexor hallucis) are inserted as 

 follows: the former goes to the second, fourth, and fifth toes, the latter to the first, third, 

 and fourth. 



Flexor brevis is very small, arising in part from the os calcis. It divides into 

 three little tendons for the second, third, and fourth toes. It receives muscular fibers in 

 common with the lumbricales from the tendons of the long flexors which go to the third 

 and fourth toes. This muscular slip represents the flexor accessorius. 



Lumbricales are four in number. The first arises from the tendon of the tibial 

 flexor, the others from the tendons of tlie fibular flexor. 



The head of flexor brevis from the tendons is very confusingly mingled with the 

 lumbricales. 



Adductor hallucis transversus arises from nearly the whole length of the fourth 

 metatarsal and from the distal ends of the shafts of the second and third. 



Adductor obliquus is hardly separable from the preceding. It arises from the 

 sheath of the peroneus longus at the basis of the second and third metatarsals. 



Interossei pedix. There is a great complication of these muscles, there being five 

 or six both dorsal and plantar. The reason for this vague enumeration appears in the 

 description. 



Dorsals. First muscle from the first and second metatarsal bones to the tibial side 

 of the second toe. The second and third muscles arise each fr(nn two bones, and are 

 inserted into the two sides of the medius, thus placing the base line in this toe. The 

 fourth muscle is a very small one, placed on the dorsal aspect of the fourth metatarsal 

 and inserted on the tibial side of the phalanx. Tiie fifth and sixth muscles arise together 

 from the last two metata'"sals and are inserted into the .adjacent sides of the last two 

 toes. This might be called a single muscle with two insertions. 



Plantar interossei. The first is where it should be, on the fibular side of the second
