The most recent and elaborate commentator even calls him an "ethnologist."
Among the passengers on the second trip was the wellknown painter and ethnologist, George Catlin, who spent several weeks at Fort Pierre studying the manners and customs of the Indians.
One of the most obscure questions with which the ethnologist has to deal is that of the prehistoric remains which occur in different and widely separated parts of the oceanic region.
To me an ethnologist who speaks of Aryan race, Aryan blood, Aryan eyes and hair, is as great a sinner as a linguist who speaks of a dolichocephalic dictionary or a brachycephalic grammar."
