or JHUN, a large river of Asia, much taken notice of in ancient histories, but does not rise in the north of India, as most writers affirm; for, according to the best and latest maps made by those who have been upon the spot, it ran a course of about 260 miles from the Caspian sea to the lake Aral, whose dimensions have lately been discovered, and is but very lately known to the Europeans; but, as it passes through a desert country abounding with sands, the inhabitants so diverted its course, that the old channel can hardly be discovered.
