Note 4 — Chapter III
Reading edition
The Aryans are supposed to have originally occupied the country east of the Caspian Sea, though some authorities locate them north of it. The branches of this race are the Hindus, Persians, Greeks, Romans, Celts, Teutons, and Slavs. These branches are related in language and color, and the peoples that find their common origin in the Aryans represent a large part of the world's enterprise and progress.
