Note 43 — Chapter II
Reading edition
This expression has been used by different geographers in different senses; but I take it in its common acceptation, without reference to the more strictly physical view of Ritter and his followers in regard to Central Asia. See Prichard's Physical History of Mankind, vol. iv. p. 278, edit. 1844. At p. 92, Prichard makes the Himalaya the southern boundary of Central Asia.
