The process by which the Anchitherium has been converted into Equus is one of specialisation, or of more and more complete deviation from what might be called the average form of an ungulate mammal.

If Dichobune has a fore-toed fore foot (though I am inclined to suspect that it resembles Cainotherium), it will be a better representative of the oldest forms of the Traguline series; but Dichobune occurs in the Middle Eocene, and is, in fact, the oldest known artiodactyle mammal.

Still more perplexing are the strange and interesting forms Toxodon, Macrauchenia, Typotherium, and a new Anoplotherioid mammal (Homalodotherhon) which Dr. Cunningham sent over to me some time ago from Patagonia.

A reverence for the bear appears to be common to all North American tribes, and is based not upon anything that the animal's body yields, but perhaps on the fact that it is the largest carnivorous mammal of the continent, the most difficult to kill and extremely keen in all its senses.
