Note 537:7 — APPENDIX A.
Reading edition
The traveler, James Orton, found fossil bones of an extinct species of the horse, the mastodon, and other animals, near Punin, in South America, all of which had passed away before the arrival of the human species. This native American horse was succeeded, in after ages, by the countless herds descended from a few introduced with the Spanish colonists. (See the Andes and the Amazon, pp. 154, 155.)
