The posterior lower grinder has five groups of tubercles ; 

 that of the iippeY has six. The eight which precede" them 

 have each four groups rapged in pairs. The iburih on each 

 side has three groups ranged in a triangular form ; anc) ^the 

 three anterior, having their tubercles on a single line, ^r^ 

 almost sharp-edged; ,id-o io A'ycld biiJhlriJtri 3rji 1 



The anterior tooth fall? very edifly in pur European pi^s j 

 and I never found ii;,in the babirous'^a, the number of which; 

 should be six, but it is frequently five only, in consequence^ 

 of the casting of the anterior tp.Qtb : I found but six als» 

 in two peccaris. ;-i)r': .. ., notriyj.f; -jiU .mii r>'Mv.>.jU oJ 



The wild boaraf Ethiopia llaS'dnly,|brechteeth^ all cotp-j 

 posed of cylinders lied together like, the jvamins? of tho^e o^ 

 the elephant, and presenting circles at their, surface wherib, 

 they are filed down. They are very Uneqi>,al ; for the ]i\^t 

 has no less than twenty-three circles ranged in three lines..j 



Every species has its peculiar form of tusks ; but all the 

 tusks and all the grinders which I have pbserved, were siipi- 

 lar to those of the common wild boar. .- 



The extremities of the Sus genus have a great resemblance. 

 to those oF the ruminating animals. As it is most hkely 

 that the.;bones of the former may be;cpnfounded with thpse 

 of ' stags and sheep, it is with these last that we ought, to; 

 compare them. ' .. 



The shoulder blade, like that of the horse, has the spine 

 flattened in iVont, and more prominent in the upper third, 

 part, where it forms a hook bent backward. 



The great tuberosity of its humierus is very high, as in 

 the sheep ; but it becomes broader behind, and is followed 

 by a broad reentering arc. S ,% . '.' ,-: 



•: The cubitus is very broad ' ai)d 'distinct throughout its, 

 whole length ; the greatest part of it in the sheep is attached.. 

 In the stag it is at least itiu.ch more slender. 



The carpi have a close resemblance, with this diflference,' 

 that the trapezoidal bone is distinct in the Sz^i genus, where-; 

 as it is close in the ruminating animals; and the unciform 

 bone is narrower, whereas the os scaphoides is broader. 

 The differences in the femurs are almost incapable of de-. 

 scription in words ; but the tibia may be recognized be- 

 cause it is shorter ; its inferior head is square, and does not 

 decrease from back to front, and has no articulation for the 

 fibula. The chief ditlerence of the tarsus depends on the 

 small cuneiform bone, on the sole of the fifth toe, and on 

 ti)e OS scaphoides remaining distinct from the cuboides. As 

 to the metacarpi, the metatarsi, and the toes, they cannot 

 ke confounded.
