The change in the dentition of the Pig is represented by De Blain- 

 ville, ' Oste'ographie, Onguligrades, Sus, t. 8, and by Owen, ' Odont.' 

 554, t. 140. Buffon (Hist. Nat. v. 110) erroneously says that the 

 milk-teeth of the Pig are not changed and remain permanent. At 

 page 181 he quotes (Aristotle, Des Animaux, lib. 2. chap. 1) further 

 that the Pigs never loose any of their teeth. The crown of the 

 grinders are mauy-lobed, especially the hinder one, which is larger 

 than the rest.

 rarely deciduous); interniaxilla short ; diastema between the 

 cutting-teeth and grinders short ; canines thick, spreading out

bent up at the end ; premolars j^.
