SECOND LEFT METATARSAL, FIBULAE SURFACE OF BASE AND 



PART OF SHAFT. 



The outline of the proximal surface (Fig. 592) is usually irregu- 

 larly crescentic, with the concavity toward the fibular side. It is a 

 smooth articular surface, gently concave transversely, and successively 

 convex, concave, and convex from the plantar to the dorsal end. It 

 articulates with a crescentic facet on the tibial side of the distal sur- 

 face of the mesocuneiform.

Determination. If the bone be held with the base uppermost 

 and the plantar side toward the student, the base will incline to the 

 side to which the bone belongs. 



Muscular Attachment. The first dorsal interosseous is at- 

 tached to the tibial side of the shaft. 



THE THIRD METATARSAL BONE. 



General Description. The base is somewhat different from the 

 base of the third metatarsal. Its proximal surface (Fig. 592) is rudely
