II00FED-MAM.MAL3 — CLASSIFICATION. 133 



make np my mind to separate these so-called Omnivora from the rest of the old Pachyderms. 

 But if I escape from Scylla (this difEculty), by reversing the order in which Owen has placed 

 the Artiodactyles, and putting the Ruminants at their head instead of the Hippopotamus, takino- 

 them in the order of Rimiinants, Hippopotamus, Rhinoceros, Elephant, Horse, I fall into Charvbdis 

 (another difficulty with the Horse), which ought not to be separated far from the Ruminants. 

 Owen escapes Charybdis by placing the Horse at the head of the Pachyderms, as above noticed 

 and the Ruminants at the end of the Artiodactyles, by which means he brings these two families 

 (Horses and Ruminants) together, but then the resiilt of doing so is that he separates the two 

 tribes of Pachyderms. I see no way of escape from this dilemma but by reverting to the old 

 arrangement, and keeping the Horse as a separate and distinct family of equal value to the 

 Ruminants. 



It is to be remembered that we are at the commencement of a new thread, and are not hampered 

 by the necessity of reconciling anything to the past. Between the Seals and the hoofed-mammals 

 there is an absolute break. We may therefore commence with what we please, and I have taken 

 that group which I think gives the best and most uninterrupted connexion with those which follow. 



The arrangement which I adopt is the following, viz.: — 



UnGULATA. 3. MULTUNGULA. 



1. MoNODACTYLA — (SoHdutiffula) KoTses, &c. 1. Palceot/icridce. 



2. Artiodactyla. 2. NesodontidUe. 



\. Ruminants — Camels — Oxen — Sheep — 3. TapiridcK. 



Antelopes — Cameleopards — Deer — 4. Nasicornia. 



Musk-Deer and Chevrotaius. 5. Prohoscidea. 



2. Anoplotheridce. 



3. NoiXrB.uniinants — Swine — Hippopotamus.
