THE FOOT. 227 



The posterior face joins the os calcis, is triangular, and semi- 

 spiral. The anterior face is oblong, transversely, and is di- 

 vided by a slight vertical rising into two, for articulating with 

 the last two metatarsal bones. 



Of the Qunerforme Internum, (Premier Cuneiforme.) 



It is placed at the internal anterior extremity of the tarsus? 

 between the scaphoides and the first metatarsal bone, and may 

 be distinguished from the other cuneiforms by its greater size. 

 Its thickest part is below. 



The anterior face presents a long vertical convexity, which 

 joins the first metatarsal bone. The posterior face is not so 

 extensive, and is formed into a triangular concavity, having 

 the broadest part below, which joins the internal facet of the 

 scaphoides. The internal side is semi-cylindrical and rough; 

 it is marked, anteriorly, near its middle, by the tendon of the 

 tibialis anticus. The external side is somewhat concave, and 

 generally rough, and is marked just below its superior margin 

 by two articular facets, of which the anterior is the smaller, 

 and comes in contact with the second metatarsal bone; the 

 posterior, from its concave obliquity, gives a slope to the upper 

 margin of the bone, and is in contact with the cuneiforme me- 

 dium. 



Of the Cuneiforme Medium, (Second Cuneiforme.) 



The middle or second cuneiform bone is placed upon the 

 scaphoides, immediately on the outside of the cuneiforme in- 

 ternum. It may be distinguished by being the smallest bone of 

 the tarsus. Its figure resembles sufficiently well a wedge; the 

 base of which is above, and the edge below. 



Its posterior face is slightly concave where it joins the sca- 

 phoides; the anterior face is slightly convex, and articulates 

 with the second metatarsal bone. The internal face presents, 

 superiorly, an oblong, slightly convex, and oblique articular 

 facet, which touches the cuneiforme internum: what remains 

 of this side is rough, for the origin of Jigamentous fibres. The
