and Koriaks ; then various Mongoloids of dark colour,
the Sioux, Dacotas, Pawnees, Natchez, Seminoles, fol-
lowed by the Algonquins, Hurons, Iroquois, Delawares,
and behind these, closing the procession, the peoples
of Athabasca, of Mackenzie, all of whom, pressing
forward to Florida and Mexico, drove towards the
extreme north the unhappy Esquimaux. This hypo-
thesis offers an ex;planation of the progress along the
Ohio and the Mississippi of the constructors of the
mounds or tumuli, and the successive immigrations of
the Guatemaltecs, Yucatecs, Othomis, Quiches, Mayas,
phichimecs, and Aztecs, gradually heaped up between
the Isthmus and Texas. But in South America the
marked differences of stature, colour, physiognomy,
and cranial capacity are a puzzle to the ethnologist.
The wisest course is merely to note the thick-set form
of the Brazilian savages, both the conquerors of ancient
times, Guaranis, Caribs, and Tupis, and the conquered
races, Botocudos and Tapuyas ; the middle height, the
aquiline nose, and retreating forehead of the Peruvians;
the tall stature of the Patagonians, and the miserable
character of the Fuegians, who sometimes eat an old
woman for want of something better, and who replied
to Darwin's question as to whether they preferred
their wife or their dog, that they preferred the dog
because he could catch the otter.
