SKELETOX. 



of which is inserted the tendon of the peroneus tertius, and into 

 the posterior part, the tendon of the peroneus secundus. The 

 base, also, has a triangular flat surface, sloping considerably 

 outwards, which articulates with the cuboides. On the inter- 

 nal side is the articular facet, whereby it joins the base of the 

 fourth rnetatarsal bon-e. The base is flattened below, rough, 

 and somewhat convex above. N 



The anterior extremity is more rounded than that of the other 

 metatarsal bones, but in other respects similar. The body is 

 prismatic ; being flat below, flat internally, and slightly rounded 

 externally. 



Of the Toes. 



The toes are five in number, and named numerically, by be- 

 ginning at the great one. They each are formed by three bones 

 called the phalanges, with the exception of the great toe, which 

 has but two of them. The phalanges are distinguished into first, 

 second, and third. In. these several respects the toes correspond 

 with the fingers. 



Of the First, or Great Toe. 



The first phalanx of the great toe is longer and much larger 

 than any other. Its base is large, and forms a deep concavity 

 for receiving the end of tke metatarsal bone. Its anterior ex- 

 tremity is formed into two small condyles, for being received 

 into the second phalanx. This bone is broad and strong, being 

 semicylindrical above, and flat below. 



The second phalanx corresponds in its appearance with the 

 third of the other toes, but is much larger than any of them. Its 

 base is broad and flat, and has two superficial cavities for the 

 condyles of the first phalanx. The anterior extremity is ex- 

 panded semicircularly, and converted into a very scabrous sur- 

 face, for the firmer attachment of the soft parts about it. The 

 body of this phalanx is constricted in the middle, rounded 

 above, and flat below. 



Connected with the great toe, are two small hemispherical 

 bones, lying upon the trochlea of its metatarsal bone, and im-
