 It offers six faces: a superior, an articular face, and in contact with tin- 

 calcaucus ; an inferior, also articular, responding to the principal and external 

 rudimentary metatursal bones; an internal, furnished with three facets for 

 contact with the scaphoid and great cuneiform, and crossed from before 

 to behind by a fissure, which forms with these two bones a vascular canal : 

 ;iu ('sternal, an anterior, and A posterior, covered with imprints. 



Scaphoid bone (the large cuneiform of Porcivall). Flattened above and 

 below, it is described as having two faces and a circumference. The faces, 

 both articular, are furrowed by a channel of insertion, and are distingniflhed 

 as superior and inferior. The first is concave, and responds to the, astra- 

 galus ; the second is convex and in contact with the two cuneiform bonus. 

 The circumference offers, outwardly, two small facets which are adapt 1 to 

 similar facets on the cuboid bone. For the remainder of its extent, it is 

 covered with imprints. 



Great Cuneiform bone (the middle cuneiform of Percivall). Flattened 

 above and below, and triangular in shape, this bone is much smaller than 

 the scaphoid, though resembling it in a striking manner. Its superior face 

 is in contact with the latter bone, and its inferior face articulates with tin- 

 middle and internal lateral metatorsal bones. Its external border is 

 provided with one or two facets to correspond with the cuboid bone ; and its 

 internal border also offers one, which is in contact with another on the small 

 cuneiform. Its anterior border is roughened throughout its extent.

Small Cuneiform bone. Situated at the inner side of the tarsus, this 

 bone, the smallest of any yet examined, is elongated from before to behind, 

 flattened on both sides, and wedged in between tho os scaphoides, the large 

 cuneiform bone, and the large and internal small rudimentary metatarsal 

 boms, with which it corn 'spends by four articular facets : a superior, two 

 inferior, and one internal. When this bone is in two portions, there are 

 then three cuneiforms, which may bo distinguished, as in Man, by naming 

 them first, second, an 1 tlilnl.
