*unt." p. 83. Hermann finally gave it the generic name of Hy- 

 rax, which Illiger adopting, placed the animal itself in his Pro- 

 dromus, p. 95, as the link between the Cavies and the Bruta of 

 Linnaeus. In the Regne Animal, we discover this puzzling genus 

 forming together with the Rhinoceros one small group of the 

 Ungulata, with the observation that, " en les examinant bien 

 on trouve qu'^ la corne pr^s ce sont en quelque sorte de Rhino- 

 ceros en miniature." (vol. i. p. 240.) Hence it is allowable, I 

 conceive, to pass from the Glires to the Ungulata. 



When Dampier and Ray assigned the name of Sea Cow to 

 the Manati of the West Indies, they probably gave the hint of 

 that anatomical affinity to Ungulata, which has been followed up 

 and proved by subsequent zoologists. Accordingly, Linnaeus 

 went so far as to place the Manati among his Bruta. And 

 M. de Blainville, trusting entirely to the principle of division, 

 and ignorant of the maxim of variation, has said* that, " le 

 Lamantin appartient au groupe qui contient les Elephans dont 

 il n'est qu'une modification propre a vivre dans I'eau." Now, 

 though it is difficult to look at a Manati or Dugong, and call it 

 an Elephant, it is impossible to deny that it is a modification of 

 the Pachyderm form ; and therefore we cannot refuse our assent 

 to the accuracy of M. Cuvier in making the Herbivorous Ce- 

 tacea follow the Ungulata in the arrangement of the Regne 

 Animal. 



Arrived thus, then, among those enormous Mammalia, which 

 Nature points out to us as the direct medium of her transition 

 from the Quadruped form to that of Fish, we proceed in the 

 series of Mammalia to the genera Trichecus and Phoca. It is 

 true indeed, that M. Cuvier, from the artificial plan of the 

 Regne Anitnal, is obliged to deny this affinity, or at least to 

 make no mention of it in the work : but it has been noticed
